are a materials company focused on developing, manufacturing and selling silicon nitride ceramics that are used in medical implants
and in a variety of industrial devices. At present, we commercialize silicon nitride in the spine implant market. We believe that
our versatile silicon nitride manufacturing expertise positions us favorably to introduce new and innovative devices in
the medical and non-medical fields. We also believe that we are the first and only company to commercialize silicon nitride medical
implants.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0.1in; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">We
have received 510(k) regulatory clearance in the United States, a CE mark in Europe, ANVISA approval in Brazil , and ARTG and
Prostheses approvals in Australia for a number of our devices that are designed for spinal fusion surgery. To date, more than
33,000 of our silicon nitride devices have been implanted into patients, with a 10-year successful track record. In March 2018,
we received clearance from the United States Food and Drug Administration, or FDA, to market a modified novel composite spinal
fusion device that combines porous and solid silicon nitride, and is comparable to our commercially-available Valeo&reg;C cervical
implants. </FONT></P>

believe that silicon nitride has a superb combination of properties that make it ideally suited for human implantation. Other
biomaterials are based on bone grafts, metal alloys, and polymers- all of which have practical limitations. In contrast, silicon
nitride has a legacy of success in the most demanding and extreme industrial environments. As a human implant material, silicon
nitride offers bone ingrowth, resistance to bacterial infection, resistance to corrosion, superior strength and fracture resistance,
and ease of diagnostic imaging, among other advantages.</FONT></P>

market and sell our Valeo brand of silicon nitride implants to surgeons and hospitals in the United States and to selected markets
in Europe and South America through more than 50 independent sales distributors who are supported by an in-house sales and marketing
management team. These implants are designed for use in cervical (neck) and thoracolumbar (lower back) spine surgery. In 2016,
we entered into a 10-year exclusive distribution agreement with Shandong Weigao Orthopaedic Device Company Limited (&ldquo;Weigao&rdquo;)
to sell Amedica-branded silicon nitride spinal fusion devices within the People&rsquo;s Republic of China (&ldquo;China&rdquo;).
Weigao, a large orthopedic company, has expertise in acquiring Chinese Food and Drug Administration (&ldquo;CFDA&rdquo;) approval
of medical devices, and will assist us in obtaining regulatory approval. Weigao has committed to minimum purchase requirements
totaling 225,000 implants in the first six years following CFDA clearance. We are also working with other partners in Japan to
obtain regulatory approval for silicon nitride in that country. China and Japan are relevant because historically, ceramic implants
are more familiar to, and more readily accepted by surgeons outside the United States, i.e., in Asia and Europe.</FONT></P>

addition to silicon nitride, we also sell metal-based products in the United States that provide surgeons and hospitals with a
complete package for spinal surgery. These metal products are designed to address spinal deformity and degenerative conditions.
Although these metal products have accounted for approximately 53% and 48% of our product revenues for each of the years
ended December 31, 2017 and 2016 , respectively, we remain focused on developing and promoting silicon nitride, and
driving its adoption through a scientifically-intense, data-driven strategy.</FONT></P>

addition to direct sales, we have targeted original equipment manufacturer (&ldquo;OEM&rdquo;) and private label partnerships
in order to accelerate adoption of silicon nitride, both in the spinal space, and also in future markets such as hip and knee
replacements, dental, extremities, trauma, and sports medicine. Existing biomaterials, based on plastics, metals, and bone grafts
have well-recognized limitations that we believe are addressed by silicon nitride, and we are uniquely positioned to convert existing,
successful implant designs made by other companies into silicon nitride. We believe OEM and private label partnerships will allow
us to work with a variety of partners, accelerate the adoption of silicon nitride, and realize incremental revenue at improved
operating margins, when compared to the cost-intensive direct sales model.</FONT></P>

current corporate strategy includes the possibility of entering into additional collaborative arrangements with third parties

strategy, we continue to seek to identify opportunities and, if possible, secure a transaction or transactions relating to our
business, including, but not limited to, partnering or other collaborative agreements, a sale of the Company or of assets and/or
other strategic arrangements. There can be no assurance that the exploration of strategic alternatives will result in any agreements

to successfully execute a strategic transaction we may be unable to continue as a going concern.</FONT></FONT> </P>

report from our independent registered public accounting firm for the year ended December 31, 2017 includes an explanatory paragraph
stating that our recurring losses from operations raises substantial doubt about our ability to continue as a going concern. If
we are unable to obtain sufficient additional funding, including through this offering, our business, prospects, financial condition
and results of operations will be materially and adversely affected and we may be unable to continue as a going concern. In addition,
we are continuing to identify strategic opportunities and, if possible, secure a transaction or transactions relating to our business,
including, but not limited to, partnering or other collaborative agreements, a sale of the Company or of assets and/or other strategic
arrangements. Even if we are able to obtain sufficient additional funding through this offering, we may not be able to continue
to operate successfully without entering into a strategic transaction. There can be no assurance that the exploration of strategic
alternatives will result in any agreements or transactions, or that, if completed, any agreements or transactions will be successful
or on attractive terms. Moreover, our current capital structure may make it difficult to consummate a strategic transaction.</FONT> </P>

doubt about our ability to continue as a going concern. If we seek additional financing to fund our business activities in the

outstanding to purchase a total of 1,563,430 shares of our Common Stock, all of which expire between August 2018 and March 2023.
Each of these warrants entitles the holder to purchase one share of Common Stock at prices ranging from $2.00 to $9,279.00 per
common share, with a weighted average exercise price of $9.04 per share. Certain of these warrants have a net exercise provision
under which its holder may, in lieu of payment of the exercise price in cash, surrender the warrant and receive a net number of
shares based on the fair market value of our Common Stock at the time of exercise of the warrant after deduction of the aggregate
exercise price. Each of these warrants also contains provisions for the adjustment of the exercise price and the aggregate number
of shares issuable upon the exercise of the warrant in the event of dividends, share splits, reorganizations, reclassifications
and consolidations. 70,426 of these warrants contain a provision requiring a reduction to the exercise price in the event we
issue Common Stock, or securities convertible into or exercisable for Common Stock, at a price per share lower than the warrant
exercise price, which provision will be triggered by this offering. </P>

LLC (&ldquo;North Stadium&rdquo;), a company owned and controlled by the Company&rsquo;s Chief Executive Officer and Chairman
of the Board, Dr. Sonny Bal. In connection with the North Stadium Loan, the Company issued to North Stadium a Secured Promissory
Note in the amount of $2.5 million (the &ldquo;North Stadium Note&rdquo;). The North Stadium Note bears interest at the rate of
10% per annum, requires the Company to make monthly interest only payments for a period of 12 months, and principal and any unpaid
accrued interest are due and payable 12 months from the effective date of the North Stadium Note, July 28, 2017. The North Stadium
Note is secured by substantially all of the assets of the Company pursuant to a security agreement between the Company and North
Stadium dated July 28, 2017, and is junior to other previously existing security interests in such assets. The North Stadium Note

the North Stadium Warrant and receive a net number of shares of Common Stock based on the fair market value of our Common Stock

Board of Directors; Appointment of Directors to Fill Vacancies; Removal of Directors for Cause. </I>Our restated certificate of
incorporation provides that our board of directors will be divided into three classes as nearly equal in number as possible. Each
year the stockholders will elect the members of one of the three classes to a three-year term of office. All directors elected
to our classified board of directors will serve until the election and qualification of their respective successors or their earlier
resignation or removal. The board of directors is authorized to create new directorships and to fill any positions so created
and is permitted to specify the class to which any new position is assigned. The person filling any of these positions would serve
for the term applicable to that class. The board of directors (or its remaining members, even if less than a quorum) is also empowered
to fill vacancies on the board of directors occurring for any reason for the remainder of the term of the class of directors in
which the vacancy occurred. Members of the board of directors may only be removed for cause and only by the affirmative vote of
holders of at least 75% of our outstanding voting stock. These provisions are likely to increase the time required for stockholders
to change the composition of the board of directors. For example, in general, at least two annual meetings will be necessary for
stockholders to effect a change in a majority of the members of the board of directors.</FONT></P>

that is not approved by our board of directors.</FONT></P>

the stockholder must first have given timely notice of the proposal in writing to our Secretary. For an annual meeting, a stockholder&rsquo;s
notice generally must be delivered not less than 90 days nor more than 120 days prior to the anniversary of the mailing date of
the proxy statement for the previous year&rsquo;s annual meeting. For a special meeting, the notice must generally be delivered
no less than 60 days nor more than 90 days prior to the special meeting or ten days following the day on which public announcement
of the meeting is first made. Detailed requirements as to the form of the notice and information required in the notice are specified
in our restated bylaws. If it is determined that business was not properly brought before a meeting in accordance with our bylaw

also required for any amendment to, or repeal of, our restated bylaws by the stockholders. Our restated bylaws may be amended

would not permit the transfer of basis in the redeemed shares of the Series B Preferred Stock to the remaining shares held (directly
or indirectly) by the redeemed U.S. holder. Instead, the unrecovered basis in our Series B Preferred Stock would be treated as
a deferred loss to be recognized when certain conditions are satisfied. These proposed Treasury regulations would be effective
for transactions that occur after the date the regulations are published as final Treasury regulations. There can, however, be
no assurance as to whether, when, and in what particular form such proposed Treasury regulations will ultimately be finalized.
If a redemption of shares is not treated as a distribution taxable as a dividend, it will be treated as a taxable sale or exchange
in the manner described under the heading &ldquo;U.S. Holders&mdash;Gain on Sale, Exchange or Other Taxable Disposition.&rdquo;</FONT></FONT> </P>

871(m) of the Code requires withholding (up to 30%, depending on whether a treaty applies) on certain financial instruments to
the extent that the payments or deemed payments on the financial instruments are contingent upon or determined by reference to
U.S.-source dividends. Under U.S. Treasury regulations promulgated under Section 871(m), certain payments or deemed payments to
non-U.S. holders with respect to certain equity-linked instruments (&ldquo;specified ELIs&rdquo;) that reference U.S. stocks may
be treated as dividend equivalents (&ldquo;dividend equivalents&rdquo;) that are subject to U.S. withholding tax at a rate of
30% (or lower treaty rate). Under these U.S. Treasury Regulations, withholding may be required even in the absence of any actual
dividend related payment or adjustment made pursuant to the terms of the instrument. The regulations as originally adopted were
to be effective for all covered contracts and instruments issued on or after January 1, 2017, but the IRS has extended such date
to apply to all covered contracts and instruments issued on or after January 1, 2019. If withholding is required, we (or the applicable
paying agent) would be entitled to withhold such taxes without being required to pay any additional amounts with respect to amounts
so withheld. Non-U.S. Holders should consult with their tax advisors regarding the application of Section 871(m) and the regulations
thereunder in respect of their acquisition and ownership of the Series B Preferred Stock and the Warrants.</FONT></FONT> </P>

commonly known as the Foreign Account Tax Compliance Act, or FATCA, and guidance issued thereunder may impose withholding taxes
on certain types of payments made to &ldquo;foreign financial institutions&rdquo; (as specifically defined) and certain other
non-U.S. entities (including financial intermediaries). Under FATCA, failure to comply with certification, information reporting
and other specified requirements could result in withholding tax being imposed on payments of dividends and sales proceeds of
any property of a type which can produce U.S. source dividends to foreign intermediaries and certain non-U.S. holders. FATCA imposes
a 30% withholding tax on dividends or gross proceeds from the sale or other disposition of the shares of our Series B Preferred
Stock and the shares of our Common Stock issuable on conversion of such Series B Preferred Stock paid to a foreign financial institution
or to a non-financial foreign entity, unless (i) the foreign financial institution undertakes certain diligence and reporting
obligations, (ii) the non-financial foreign entity either certifies it does not have any &ldquo;substantial United States owners&rdquo;
as specifically defined in FATCA or furnishes identifying information regarding each substantial United States owner or (iii)
the foreign financial institution or the non-financial foreign entity qualifies for an exemption from the withholding tax. We
intend to treat the Warrants as also subject to FATCA. If the payee is a foreign financial institution, in the absence of any
applicable exemption, it must enter into an agreement with the United States Treasury requiring, among other things, that it undertake
to identify accounts held by certain United States persons or United States-owned foreign entities, annually report certain information
about such accounts, and withhold 30% on &ldquo;withholdable payments&rdquo; (as specifically defined) made to certain account
holders. An intergovernmental agreement between the United States and the foreign entity&rsquo;s jurisdiction may modify these
requirements. Under certain transition rules, any obligation to withhold under FATCA with respect to payments of dividends on
the Series B Preferred Stock and the Common Stock is currently in effect, but with respect to the gross proceeds of a sale or
other disposition of the Series B Preferred Stock, the Warrants or the Common Stock the obligation to withhold under FATCA will
not begin until January 1, 2019. Prospective investors should consult their tax advisors regarding the implications of FATCA with
respect to an investment in the Series B Preferred Stock and related Warrants.</FONT></FONT> </P>

to employees pursuant to the Company&rsquo;s employee stock purchase plans or pursuant to the conversion and/or exercise of Common
Stock Equivalents outstanding as of the date of the most recently filed periodic report under the Exchange Act. No Person has
any right of first refusal, preemptive right, right of participation, or any similar right to participate in the transactions
contemplated by the Transaction Documents, except such Persons as are participating in the transactions contemplated by the Transaction
Documents or who have waived such rights on or prior to the date hereof as set forth on Schedule 3.1(e) of the Disclosure Schedules.
Except as a result of the purchase and sale of the Securities, there are no outstanding options, warrants, scrip rights to subscribe

or exchangeable for, or giving any Person any right to subscribe for or acquire, any shares of Common Stock, or contracts, commitments,
understandings or arrangements by which the Company or any Subsidiary is or may become bound to issue additional shares of Common
Stock or Common Stock Equivalents. Except as set forth on Schedule 3.1(h) of the Disclosure Schedules, the issuance and sale of
the Securities will not obligate the Company to issue shares of Common Stock or other securities to any Person (other than the
Underwriters) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange
or reset price under any of such securities. All of the outstanding shares of capital stock of the Company are duly authorized,
validly issued, fully paid and nonassessable, have been issued in compliance with all federal and state securities laws, and none
of such outstanding shares was issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities.
The authorized shares of the Company conform in all material respects to all statements relating thereto contained in the Registration
Statement and the Prospectus. The offers and sales of the Company&rsquo;s securities were at all relevant times either registered
under the Securities Act and the applicable state securities or Blue Sky laws or, based in part on the representations and warranties
of the purchasers, exempt from such registration requirements. No further approval or authorization of any stockholder, the Board
of Directors or others is required for the issuance and sale of the Securities. There are no stockholders agreements, voting agreements

shorter period as the Company was required by law or regulation to file such material) (the foregoing materials, including the
exhibits thereto and documents incorporated by reference therein, together with the Prospectus and any Prospectus Supplement,
being collectively referred to herein as the &ldquo;<U>SEC Reports</U>&rdquo;) on a timely basis or has received a valid extension
of such time of filing any such SEC Reports prior to the expiration of any such extension. As of their respective dates, the
SEC Reports complied in all material respects with the requirements of the Securities Act and the Exchange Act, as applicable,
and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which
they were made, not misleading. The consolidated financial statements of the Company and its consolidated Subsidiaries included
in the SEC Reports, the Registration Statement, the Preliminary Prospectus and the Prospectus comply in all material respects
with applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the
time of filing. Such financial statements have been prepared in accordance with United States generally accepted accounting principles
applied on a consistent basis during the periods involved (&ldquo;<U>GAAP</U>&rdquo;), except as may be otherwise specified in
such financial statements or the notes thereto and except that unaudited financial statements may not contain all footnotes required
by GAAP, and fairly present in all material respects the financial position of the Company and its consolidated Subsidiaries as
of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of
unaudited statements, to normal, immaterial, year-end audit adjustments. The agreements and documents described in the Registration

thereof contained therein and there are no agreements or other documents required by the Securities Act and the rules and regulations
thereunder to be described in the Registration Statement, the Preliminary Prospectus, the Prospectus or the SEC Reports or to
be filed with the Commission as exhibits to the Registration Statement, that have not been so described or filed. Each agreement
or other instrument (however characterized or described) to which the Company is a party or by which it is or may be bound or
affected and (i) that is referred to in the Registration Statement, the Prospectus or the SEC Reports, or (ii) is material to
the Company&rsquo;s business, has been duly authorized and validly executed by the Company, is in full force and effect in all
material respects and is enforceable against the Company and, to the Company&rsquo;s knowledge, the other parties thereto, in
accordance with its terms, except (x) as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar
laws affecting creditors&rsquo; rights generally, (y) as enforceability of any indemnification or contribution provision may be
limited under the federal and state securities laws, and (z) that the remedy of specific performance and injunctive and other
forms of equitable relief may be subject to the equitable defenses and to the discretion of the court before which any proceeding
therefore may be brought. None of such agreements or instruments has been assigned by the Company, and neither the Company nor,
to the best of the Company&rsquo;s knowledge, any other party is in default thereunder and, to the best of the Company&rsquo;s
knowledge, no event has occurred that, with the lapse of time or the giving of notice, or both, would constitute a default thereunder.
To the best of the Company&rsquo;s knowledge, performance by the Company of the material provisions of such agreements or instruments
will not result in a violation of any existing applicable law, rule, regulation, judgment, order or decree of any governmental
agency or court, domestic or foreign, having jurisdiction over the Company or any of its assets or businesses, including, without

the amount that will be required to be paid on or in respect of the Company&rsquo;s existing debts and other liabilities (including
known contingent liabilities) as they mature, (ii) the Company&rsquo;s assets do not constitute unreasonably small capital to
carry on its business as now conducted and as proposed to be conducted including its capital needs taking into account the particular
capital requirements of the business conducted by the Company, consolidated and projected capital requirements and capital availability
thereof, and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate
all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in
respect of its liabilities when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability
to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt).
The Company has no knowledge of any facts or circumstances which lead it to believe that it will file for reorganization or liquidation

The Company is not a party to an &ldquo;employee benefit plan,&rdquo; as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended (&ldquo;<U>ERISA</U>&rdquo;), which: (i) is subject to any provision of ERISA and (ii) is or
was at any time maintained, administered or contributed to by the Company or any of its ERISA Affiliates (as defined hereafter).
These plans are referred to collectively herein as the &ldquo;Employee Plans.&rdquo; An &ldquo;<U>ERISA Affiliate</U>&rdquo; of
any person or entity means any other person or entity which, together with that person or entity, could be treated as a single
employer under Section 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986, as amended (the &ldquo;<U>Code</U>&rdquo;).
Each Employee Plan has been maintained in material compliance with its terms and the requirements of applicable law. No Employee
Plan is subject to Title IV of ERISA. The Registration Statement, Preliminary Prospectus and the Prospectus identify each employment,
severance or other similar agreement, arrangement or policy and each material plan or arrangement required to be disclosed pursuant
to the Rules and Regulations providing for insurance coverage (including any self-insured arrangements), workers&rsquo; compensation,
disability benefits, severance benefits, supplemental unemployment benefits, vacation benefits or retirement benefits, or deferred
compensation, profit-sharing, bonuses, stock options, stock appreciation rights or other forms of incentive compensation, or post-retirement
insurance, compensation or benefits, which: (i) is not an Employee Plan; (ii) is entered into, maintained or contributed to, as
the case may be, by the Company or any of its ERISA Affiliates; and (iii) covers any officer or director or former officer or
director of the Company or any of its ERISA Affiliates. These agreements, arrangements, policies or plans are referred to collectively
as &ldquo;<U>Benefit Arrangements</U>.&rdquo; Each Benefit Arrangement has been maintained in material compliance with its terms
and with the requirements of applicable law. Except as disclosed in the Registration Statement, Preliminary Prospectus and the
Prospectus, there is no liability in respect of post-retirement health and medical benefits for retired employees of the Company
or any of its ERISA Affiliates, other than medical benefits required to be continued under applicable law. No &ldquo;prohibited
transaction&rdquo; (as defined in either Section 406 of ERISA or Section 4975 of the Code) has occurred with respect to any Employee
Plan; and each Employee Plan that is intended to be qualified under Section 401(a) of the Code is so qualified, and nothing has
occurred, whether by action or by failure to act, which could cause the loss of such qualification.</FONT></FONT></P>

have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the
expense of such Underwriter, such Selected Dealer or Controlling Person unless (i) the employment of such counsel at the expense

Preferred Stock owned subsequent to the conversion at issue and the date on which such conversion is to be effected, which

respect to which the Preferred Stock has been converted, irrespective of the date such Conversion Shares are credited to the
Holder&rsquo;s Depository Trust Company account or the date of delivery of the certificates evidencing such Conversion
Shares, as the case may be. A beneficial owner of shares of Preferred Stock held in electronic form through a broker, bank or
other nominee may submit an informational Notice of Conversion to the Corporation via facsimile or email and upon the
Corporation&rsquo;s receipt or deemed receipt of such notice, such beneficial owner shall be deemed to have become the holder
of record of the Conversion Shares for all corporate purposes. No ink-original Notice of Conversion shall be required, nor

error. To effect conversions of shares of Preferred Stock, a Holder shall not be required to surrender the certificate(s)
representing the shares of Preferred Stock to the Corporation unless all of the shares of Preferred Stock represented thereby
are so converted, in which case such Holder shall deliver the certificate representing such shares of Preferred Stock

Corporation, in electronic form, the number of shares of Preferred Stock being converted. Such converted Series B Preferred
Stock shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may thereafter
take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of
shares of Series B Preferred Stock accordingly.</FONT></P>

<U>Obligation Absolute; Partial Liquidated Damages</U>. The Corporation&rsquo;s obligation to issue and deliver the Conversion
Shares upon conversion of Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of
any action or inaction by a Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery
of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination,
or any breach or alleged breach by such Holder or any other Person of any obligation to the Corporation or any violation or alleged
violation of law by such Holder or any other person, and irrespective of any other circumstance which might otherwise limit such
obligation of the Corporation to such Holder in connection with the issuance of such Conversion Shares; provided, however, that
such delivery shall not operate as a waiver by the Corporation of any such action that the Corporation may have against such Holder.
In the event a Holder shall elect to convert any or all of the Stated Value of its Preferred Stock, the Corporation may not refuse
conversion based on any claim that such Holder or anyone associated or affiliated with such Holder has been engaged in any violation
of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and/or enjoining
conversion of all or part of the Preferred Stock of such Holder shall have been sought and obtained, and the Corporation posts
a surety bond for the benefit of such Holder in the amount of 150% of the Stated Value of Preferred Stock which is subject to
the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the underlying dispute and
the proceeds of which shall be payable to such Holder to the extent it obtains judgment. In the absence of such injunction, the
Corporation shall issue Conversion Shares and, if applicable, cash, upon a properly noticed conversion. If the Corporation fails
to deliver to a Holder such Conversion Shares pursuant to Section 5(c)(i) by the Share Delivery Date applicable to such conversion,
the Corporation shall pay to such Holder, in cash, as liquidated damages and not as a penalty, for each $5,000 of Stated Value
of Preferred Stock being converted, $50 per Trading Day (increasing to $100 per Trading Day on the third Trading Day and increasing
to $200 per Trading Day on the sixth Trading Day after such damages begin to accrue) for each Trading Day after the Share Delivery
Date until such Conversion Shares are delivered or Holder rescinds such conversion. Nothing herein shall limit a Holder&rsquo;s
right to pursue actual damages for the Corporation&rsquo;s failure to deliver Conversion Shares within the period specified herein
and such Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit a Holder
from seeking to enforce damages pursuant to any other Section hereof or under applicable law.</FONT></P>

<U>Compensation for Buy-In on Failure to Timely Deliver Conversion Shares Upon Conversion</U>. In addition to any other rights
available to the Holder, if the Corporation fails for any reason to deliver to a Holder the applicable Conversion Shares by the
Share Delivery Date pursuant to Section 5(c)(i), and if after such Share Delivery Date such Holder is required by its brokerage
firm to purchase (in an open market transaction or otherwise), or the Holder&rsquo;s brokerage firm otherwise purchases, shares
of Common Stock to deliver in satisfaction of a sale by such Holder of the Conversion Shares which such Holder was entitled to
receive upon the conversion relating to such Share Delivery Date (a &ldquo;<U>Buy-In</U>&rdquo;), then the Corporation shall (A)
pay in cash to such Holder (in addition to any other remedies available to or elected by such Holder) the amount, if any, by which
(x) such Holder&rsquo;s total purchase price (including any brokerage commissions) for the Common Stock so purchased exceeds (y)
the product of (1) the aggregate number of shares of Common Stock that such Holder was entitled to receive from the conversion
at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed
(including any brokerage commissions) and (B) at the option of such Holder, either reissue (if surrendered) the shares of Preferred
Stock equal to the number of shares of Preferred Stock submitted for conversion (in which case, such conversion shall be deemed
rescinded) or deliver to such Holder the number of shares of Common Stock that would have been issued if the Corporation had timely
complied with its delivery requirements under Section 5(c)(i). For example, if a Holder purchases shares of Common Stock having
a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Preferred Stock with
respect to which the actual sale price of the Conversion Shares (including any brokerage commissions) giving rise to such purchase
obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Corporation shall be required to
pay such Holder $1,000. The Holder shall provide the Corporation written notice indicating the amounts payable to such Holder
in respect of the Buy-In and, upon request of the Corporation, evidence of the amount of such loss. Nothing herein shall limit
a Holder&rsquo;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 Corporation&rsquo;s failure to timely deliver the

<U>Beneficial Ownership Limitation</U>. The Corporation shall not effect any conversion of the Preferred Stock, and a Holder shall
not have the right to convert any portion of the Preferred Stock, to the extent that, after giving effect to the conversion set
forth on the applicable Notice of Conversion, such Holder (together with such Holder&rsquo;s Affiliates, and any Persons acting
as a group together with such Holder or any of such Holder&rsquo;s Affiliates (such Persons, &ldquo;<U>Attribution Parties</U>&rdquo;))
would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence,
the number of shares of Common Stock beneficially owned by such Holder and its Affiliates and Attribution Parties shall include
the number of shares of Common Stock issuable upon conversion of the Preferred Stock with respect to which such determination
is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion of the remaining,
unconverted Stated Value of Preferred Stock beneficially owned by such Holder or any of its Affiliates or Attribution Parties
and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Corporation subject to
a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, the Preferred
Stock or the Warrants) beneficially owned by such Holder or any of its Affiliates or Attribution Parties. Except as set forth
in the preceding sentence, for purposes of this Section 5(d), beneficial ownership shall be calculated in accordance with Section
13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation contained in
this Section 5(d) applies, the determination of whether the Preferred Stock is convertible (in relation to other securities owned
by such Holder together with any Affiliates and Attribution Parties) and of how many shares of Preferred Stock are convertible
shall be in the sole discretion of such Holder, and the submission of a Notice of Conversion shall be deemed to be such Holder&rsquo;s
determination of whether the shares of Preferred Stock may be converted (in relation to other securities owned by such Holder
together with any Affiliates and Attribution Parties) and how many shares of the Preferred Stock are convertible, in each case
subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, each Holder will be deemed to represent
to the Corporation each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions
set forth in this paragraph and the Corporation shall have no obligation to verify or confirm the accuracy of such determination.
In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d)
of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 5(d), in determining the
number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as stated
in the most recent of the following: (i) the Corporation&rsquo;s most recent periodic or annual report filed with the Commission,
as the case may be, (ii) a more recent public announcement by the Corporation or (iii) a more recent written notice by the Corporation
or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder,
the Corporation shall within two Trading Days confirm orally and in writing to such Holder the number of shares of Common Stock
then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the
conversion or exercise of securities of the Corporation, including the Preferred Stock, by such Holder or its Affiliates or Attribution
Parties since the date as of which such number of outstanding shares of Common Stock was reported. The &ldquo;<U>Beneficial Ownership

of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock
issuable upon conversion of Preferred Stock held by the applicable Holder. A Holder, upon notice to the Corporation, may increase
or decrease the Beneficial Ownership Limitation provisions of this Section 5(d) applicable to its Preferred Stock provided that
the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock upon conversion of this Preferred Stock held by the Holder and the
provisions of this Section 5(d) shall continue to apply. Any such increase in the Beneficial Ownership Limitation will not be
effective until the 61st day after such notice is delivered to the Corporation and shall only apply to such Holder and no other
Holder. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with
the terms of this Section 5(d) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the
intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly
give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of Preferred Stock.</FONT></P>

<U>Calculation of Consideration Received</U>. If any Option and/or Common Stock Equivalent and/or Adjustment Right is issued in
connection with the issuance or sale or deemed issuance or sale of any other securities of the Corporation (as determined by the
Holder, the &ldquo;<U>Primary Security</U>&rdquo;, and such Option and/or Common Stock Equivalent and/or Adjustment Right, the
&ldquo;<U>Secondary Securities</U>&rdquo; and together with the Primary Security, each a &ldquo;<U>Unit</U>&rdquo;), together
comprising one integrated transaction, the aggregate consideration per share of Common Stock with respect to such Primary Security
shall be deemed to be the lower of (x) the purchase price of such Unit, (y) if such Primary Security is an Option and/or Common
Stock Equivalent, the lowest price per share for which one share of Common Stock is at any time issuable upon the exercise or
conversion of the Primary Security in accordance with Section 6(b)(i) or 6(b)(ii) above and (z) the lowest VWAP of the Common
Stock on any Trading Day during the four Trading Day period immediately following the public announcement of such Dilutive Issuance
(for the avoidance of doubt, if such public announcement is released prior to the opening of the Trading Market on a Trading Day,
such Trading Day shall be the first Trading Day in such four Trading Day period). If any shares of Common Stock, Options or Common
Stock Equivalents are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will
be deemed to be the net amount of consideration received by the Corporation therefor. If any shares of Common Stock, Options or
Common Stock Equivalents are issued or sold for a consideration other than cash, the amount of such consideration received by
the Corporation will be the fair value of such consideration, except where such consideration consists of publicly traded securities,
in which case the amount of consideration received by the Corporation for such securities will be the arithmetic average of the
VWAPs of such security for each of the five (5) Trading Days immediately preceding the date of receipt. If any shares of Common
Stock, Options or Common Stock Equivalents are issued to the owners of the non-surviving entity in connection with any merger
in which the Corporation is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of
such portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options
or Common Stock Equivalents (as the case may be). The fair value of any consideration other than cash or publicly traded securities
will be determined jointly by the Corporation and the Holder. If such parties are unable to reach agreement within ten (10) days
after the occurrence of an event requiring valuation (the &ldquo;<U>Valuation Event</U>&rdquo;), the fair value of such consideration
will be determined within five (5) Trading Days after the tenth (10th) day following such Valuation Event by an independent, reputable
appraiser jointly selected by the Corporation and the Holder. The determination of such appraiser shall be final and binding upon
all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Corporation.</FONT></P>

the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Preferred Stock which
is convertible for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent
to the shares of Common Stock acquirable and receivable upon conversion of this Preferred Stock (without regard to any limitations
on the conversion of this Preferred Stock) prior to such Fundamental Transaction, and with a conversion price which applies the
conversion price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common
Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital
stock and such conversion price being for the purpose of protecting the economic value of this Preferred Stock immediately prior
to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder.
Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that

as <U>Exhibit A</U> (the &ldquo;<U>Exercise Notice</U>&rdquo;), of the Holder&rsquo;s election to exercise this Warrant. The Holder
shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Partial exercises of this Warrant
resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering

of the Exercise Delivery Documents, the Holder shall be deemed for all corporate purposes to have become the holder of record
of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the certificates
evidencing such Warrant Shares. If this Warrant is submitted in connection with any exercise and the number of Warrant Shares
represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise,
then the Company shall as soon as practicable and in no event later than three Business Days after any exercise and at its own
expense, issue a new Warrant (in accordance with Section 6) representing the right to purchase the number of Warrant Shares purchasable
immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to which this Warrant is

exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder&rsquo;s Affiliates, and any other
persons acting as a group together with the Holder or any of the Holder&rsquo;s Affiliates), would beneficially own in excess
of the Beneficial Ownership Limitation, as defined below. For purposes of the foregoing sentence, the number of shares of Common
Stock beneficially owned by the Holder and its Affiliates shall include the number of shares of Common Stock issuable upon exercise
of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common Stock
which would be issuable upon (i) exercise of the remaining, non-exercised portion of this Warrant beneficially owned by the Holder
or any of its Affiliates and (ii) exercise or conversion of the unexercised or non-converted portion of any other securities of
the Company (including without limitation any other Common Stock Equivalents) subject to a limitation on conversion or exercise
analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates. Except as set forth in
the preceding sentence, for purposes of this paragraph (d), beneficial ownership shall be calculated in accordance with Section
13(d) of the Exchange Act, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation
is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be
filed in accordance therewith. To the extent that the limitation contained in this paragraph applies, the determination of whether
this Warrant is exercisable (in relation to other securities owned by the Holder together with any affiliates) and of which portion
of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall
be deemed to be the Holder&rsquo;s determination of whether this Warrant is exercisable (in relation to other securities owned
by the Holder together with any Affiliates) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial
Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination.</FONT></P>

purposes of this paragraph, in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of
outstanding shares of Common Stock as reflected in (A) the Company&rsquo;s most recent periodic or annual report filed with the
Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by the
Company or its transfer agent setting forth the number of shares of Common Stock outstanding. Upon the request of a Holder, the
Company shall within two Trading Days confirm to the Holder the number of shares of Common Stock then outstanding. In any case,
the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities
of the Company, including this Warrant, by the Holder or its affiliates since the date as of which such number of outstanding
shares of Common Stock was reported. The &ldquo;<U>Beneficial Ownership Limitation</U>&rdquo; shall be 4.99% of the number of
shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon
exercise of this Warrant. The limitations contained in this paragraph shall apply to a successor Holder of this Warrant. The Company
covenants that this Warrant is outstanding, the Company will reserve from its authorized and unissued Common Stock a number of
shares, free from preemptive rights, equal to three times the number of shares that is actually issuable upon full exercise of
the Warrant (based on the Exercise Price in effect at that time). Notwithstanding anything in this Warrant to the contrary, and
in addition to the beneficial ownership limitations provided herein, the total number of shares of Common Stock that may be issued
under this Warrant and that certain Promissory Note dated January 30, 2018 in the principal amount of $840,000 (the &ldquo;Note&rdquo;),
shall be limited to 19.99% of the Company&rsquo;s outstanding shares of Common Stock as of the date hereof (the &ldquo;Exchange
Cap&rdquo;), unless stockholder approval is obtained to issue more than the Exchange Cap. The Exchange Cap shall be appropriately
adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction.</FONT></P>

the provisions of Section 2(d)(i) above pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such
date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder&rsquo;s brokerage
firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which
the Holder anticipated receiving upon such exercise (a &ldquo;<U>Buy-In</U>&rdquo;), then the Company shall (A) pay in cash to
the Holder the amount, if any, by which (x) the Holder&rsquo;s total purchase price (including brokerage commissions, if any)
for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that
the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell
order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion
of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall
be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company
timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having
a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate
sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company
shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable
to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall
limit a Holder&rsquo;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&rsquo;s failure to timely deliver shares
of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.</FONT></P>

<U>Holder&rsquo;s Exercise Limitations</U>. The Company shall not effect any exercise of this Warrant, and a Holder shall not
have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect
to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder&rsquo;s
Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder&rsquo;s Affiliates (such Persons,
&ldquo;<U>Attribution Parties</U>&rdquo;)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined
below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its
Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with
respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable
upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates
or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the
Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on conversion or exercise
analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties.
Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in
accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged
by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of
the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent
that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation
to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant
is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be
the Holder&rsquo;s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together
with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each case subject to the
Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination.
In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d)
of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(e), in determining the
number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected
in (A) the Company&rsquo;s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent
public announcement by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the
number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading
Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number
of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the
Company, including this Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number
of outstanding shares of Common Stock was reported. The &ldquo;<U>Beneficial Ownership Limitation</U>&rdquo; shall be 4.99% (or,
upon election by a Holder prior to the issuance of any Warrants, 9.99%) of the number of shares of the Common Stock outstanding
immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The Holder,
upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided
that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions
of this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until
the 61<SUP>st</SUP> day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and
implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or
any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained
or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained
in this paragraph shall apply to a successor holder of this Warrant.</FONT></P>

<U>Fundamental Transaction</U>. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in

offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell,

Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making
or party to, such stock or share purchase agreement or other business combination) (each a &ldquo;<U>Fundamental Transaction</U>&rdquo;),
then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would
have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the
Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant), the number of shares of Common Stock
of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration
(the &ldquo;<U>Alternate Consideration</U>&rdquo;) receivable as a result of such Fundamental Transaction by a holder of the number
of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard
to any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination of the
Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise
Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the
Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon
any exercise of this Warrant following such Fundamental Transaction. Notwithstanding anything to the contrary, in the event of
a Fundamental Transaction other than one in which a Successor Entity (as defined below) that is a publicly traded corporation
whose stock is quoted or listed on a Trading Market assumes this Warrant such that the Warrant shall be exercisable for the publicly
traded common stock of such Successor Entity and only if such Fundamental Transaction is within the Company&rsquo;s control, the
Company or any Successor Entity shall, at the Holder&rsquo;s option, exercisable at any time concurrently with, or within 30 days
after, the consummation of the Fundamental Transaction, purchase this Warrant from the Holder by paying to the Holder an amount
of cash equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date of the consummation
of such Fundamental Transaction; <U>provided</U>, <U>however</U>, if the Fundamental Transaction is not within the Company&rsquo;s
control, including not approved by the Company&rsquo;s Board of Directors, Holder shall have the option to require the Company
or any Successor Entity to purchase its Warrant for the Black Scholes Value of the unexercised portion of this Warrant as of the
date of consummation of such Fundamental Transaction using the same type or form of consideration (and in the same proportion)
that is being offered and paid to the holders of Common Stock of the Company in connection with the Fundamental Transaction, whether
that consideration be in the form of cash, stock or any combination thereof, or whether the holders of Common Stock are given
the choice to receive from among alternative forms of consideration in connection with the Fundamental Transaction. Any cash payment
will be made by wire transfer of immediately available funds within five Business Days of the Holder&rsquo;s election (or, if
later, on the effective date of the Fundamental Transaction). &ldquo;<U>Black Scholes Value</U>&rdquo; means the value of this
Warrant based on the Black and Scholes Option Pricing Model obtained from the &ldquo;OV&rdquo; function on Bloomberg determined
as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest
rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the
applicable Fundamental Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and the 100
day volatility obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement
of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the sum of the
price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental
Transaction and (D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental
Transaction and the Termination Date. The Company shall cause any successor entity in a Fundamental Transaction in which the Company
is not the survivor (the &ldquo;<U>Successor Entity</U>&rdquo;) to assume in writing all of the obligations of the Company under
this Warrant and the other Transaction Documents in accordance with the provisions of this Section 3(e) pursuant to written agreements
prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant
a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant
which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent
to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the
exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder
to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental
Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being
for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction),
and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction,
the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction,
the provisions of this Warrant and the other Transaction Documents referring to the &ldquo;Company&rdquo; shall refer instead
to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the
Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been named
as the Company herein. For the avoidance of doubt, if, at any time while this Warrant is outstanding, a Fundamental Transaction
occurs, pursuant to the terms of this Section 5(e), the Holder shall not be entitled to receive more than one of (i) the consideration
receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant
is exercisable immediately prior to such Fundamental Transaction, (ii) an amount of cash equal to the Black Scholes Value of the
remaining unconverted portion of this Warrant on the date of the consummation of such Fundamental Transaction, or (iii) the assumption
by the Successor Entity of all of the obligations of the Company under this Warrant and the other Transaction Documents and the
option to receive a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance
to this Warrant.</FONT></P>

date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder&rsquo;s brokerage
firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which
the Holder anticipated receiving upon such exercise (a &ldquo;<U>Buy-In</U>&rdquo;), then the Company shall (A) pay in cash to
the Holder the amount, if any, by which (x) the Holder&rsquo;s total purchase price (including brokerage commissions, if any)
for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that
the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell
order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion
of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall
be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company
timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having
a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate
sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company
shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable
to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall

<U>Holder&rsquo;s Exercise Limitations</U>. The Company shall not effect any exercise of this Warrant, and the Holder shall not
have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect
to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder&rsquo;s
Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder&rsquo;s Affiliates (such Persons,
&ldquo;<U>Attribution Parties</U>&rdquo;)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined
below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its
Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with
respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable
upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates
or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the
Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on conversion or exercise
analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties.
Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in
accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged
by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of
the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent
that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation
to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant
is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be
the Holder&rsquo;s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together
with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each case subject to the
Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination.
In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d)
of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(e), in determining the
number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected
in (A) the Company&rsquo;s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent
public announcement by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the
number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading
Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number
of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the
Company, including this Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number
of outstanding shares of Common Stock was reported. The &ldquo;<U>Beneficial Ownership Limitation</U>&rdquo; shall be 4.99% (or,
upon election by a Holder prior to the issuance of any Warrants, 9.99%) of the number of shares of the Common Stock outstanding
immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The Holder,
upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided
that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions
of this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until
the 61<SUP>st</SUP> day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and
implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or
any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained
or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained
in this paragraph shall apply to a successor holder of this Warrant.</FONT></P>

<U>Calculation of Consideration Received</U>. If any Option and/or Common Stock Equivalent and/or Adjustment Right is issued in
connection with the issuance or sale or deemed issuance or sale of any other securities of the Company (as determined by the Holder,
the &ldquo;<U>Primary Security</U>&rdquo;, and such Option and/or Common Stock Equivalent and/or Adjustment Right, the &ldquo;<U>Secondary
Securities</U>&rdquo; and together with the Primary Security, each a &ldquo;<U>Unit</U>&rdquo;), together comprising one integrated
transaction, the aggregate consideration per share of Common Stock with respect to such Primary Security shall be deemed to be
the lower of (x) the purchase price of such Unit, (y) if such Primary Security is an Option and/or Common Stock Equivalent, the
lowest price per share for which one share of Common Stock is at any time issuable upon the exercise or conversion of the Primary
Security in accordance with Section 3(b)(i) or 3(b)(ii) above and (z) the lowest VWAP of the Common Stock on any Trading Day during
the four Trading Day period immediately following the public announcement of such Dilutive Issuance (for the avoidance of doubt,
if such public announcement is released prior to the opening of the Trading Market on a Trading Day, such Trading Day shall be
the first Trading Day in such four Trading Day period). If any shares of Common Stock, Options or Common Stock Equivalents are
issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net
amount of consideration received by the Company therefor. If any shares of Common Stock, Options or Common Stock Equivalents are
issued or sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair
value of such consideration, except where such consideration consists of publicly traded securities, in which case the amount
of consideration received by the Company for such securities will be the arithmetic average of the VWAPs of such security for
each of the five (5) Trading Days immediately preceding the date of receipt. If any shares of Common Stock, Options or Common
Stock Equivalents are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the
surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and
business of the non-surviving entity as is attributable to such shares of Common Stock, Options or Common Stock Equivalents (as
the case may be). The fair value of any consideration other than cash or publicly traded securities will be determined jointly
by the Company and the Holder. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event
requiring valuation (the &ldquo;<U>Valuation Event</U>&rdquo;), the fair value of such consideration will be determined within
five (5) Trading Days after the tenth (10th) day following such Valuation Event by an independent, reputable appraiser jointly
selected by the Company and the Holder. The determination of such appraiser shall be final and binding upon all parties absent
manifest error and the fees and expenses of such appraiser shall be borne by the Company.</FONT></P>

<U>Holder&rsquo;s Right of Alternative Exercise Price</U>. In addition to and not in limitation of the other provisions of this
Section 3, if the Company in any manner issues or sells or enters into any agreement to issue or sell, any Common Stock, Options

<U>Fundamental Transaction</U>. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in
one or more related transactions effects any merger or consolidation of the Company with or into another Person (other than a
transaction solely to change the domicile of the Corporation), (ii) the Company, directly or indirectly, effects any sale, lease,
license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of
related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or
another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares
for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv)
the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization
of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged
for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions consummates
a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization,
spin-off or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than
50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons
making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement
or other business combination) (each a &ldquo;<U>Fundamental Transaction</U>&rdquo;), then, upon any subsequent exercise of this
Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately
prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section
2(e) on the exercise of this Warrant), the number of shares of Common Stock of the successor or acquiring corporation or of the
Company, if it is the surviving corporation, and any additional consideration (the &ldquo;<U>Alternate Consideration</U>&rdquo;)
receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant
is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise
of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to
apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in
a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common
Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder
shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such
Fundamental Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction, the Company or any
Successor Entity (as defined below) shall, at the Holder&rsquo;s option, exercisable at any time concurrently with, or within
30 days after, the consummation of the Fundamental Transaction (or, if later, the date of the public announcement of the applicable
Fundamental Transaction) (other than a Fundamental Transaction which was not approved by the Board of Directors, as to which this
right shall not apply), purchase this Warrant from the Holder by paying to the Holder an amount of cash equal to the Black Scholes
Value of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction; provided,
however, that, if the Fundamental Transaction is not within the Company&rsquo;s control, including not approved by the Company&rsquo;s
Board of Directors, Holder shall only be entitled to receive from the Company or any Successor Entity, as of the date of consummation
of such Fundamental Transaction, the same type or form of consideration (and in the same proportion), at the Black Scholes Value
(as defined below) of the unexercised portion of this Warrant, that is being offered and paid to the holders of Common Stock of
the Company in connection with the Fundamental Transaction, whether that consideration be in the form of cash, stock or any combination
thereof, or whether the holders of Common Stock are given the choice to receive from among alternative forms of consideration
in connection with the Fundamental Transaction. &ldquo;<U>Black Scholes Value</U>&rdquo; means the value of this Warrant based
on the Black and Scholes Option Pricing Model obtained from the &ldquo;OV&rdquo; function on Bloomberg determined as of the day
of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding
to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable Fundamental
Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and the 100 day volatility obtained
from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement of the applicable Fundamental
Transaction, (C) the underlying price per share used in such calculation shall be the sum of the price per share being offered
in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental Transaction and (D) a
remaining option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction
and the Termination Date. The payment of the Black Scholes Value will be made by wire transfer of immediately available funds
within five Business Days of the Holder&rsquo;s election (or, if later, on the effective date of the Fundamental Transaction).
The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the &ldquo;<U>Successor
Entity</U>&rdquo;) to assume in writing all of the obligations of the Company under this Warrant in accordance with the provisions
of this Section 3(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by
the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver
to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such
Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this
Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an
exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative
value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such
number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant
immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance
to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted
for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant referring to the &ldquo;Company&rdquo;
shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the
obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein.</FONT></P>

the principal sum of up to $840,000.00 (the &ldquo;Principal Amount&rdquo;), together with interest at the rate of eight percent
(8%) per annum (with the understanding that the initial six months of such interest of each tranche funded shall be guaranteed),
at maturity or upon acceleration or otherwise, as set forth herein (the &ldquo;Note&rdquo;). The consideration to the Borrower
for this Note is up to $750,000.00 (the &ldquo;Consideration&rdquo;) in United States currency, due to the prorated original issuance
discount of up to $75,000.00 (the &ldquo;OID&rdquo;). The Holder shall pay $500,000.00 of the Consideration (the &ldquo;First

At the closing of the First Tranche, the outstanding principal amount under this Note shall be $565,000.00, consisting of the
First Tranche, plus the prorated portion of the OID (as defined herein) and a $15,000.00 credit for the Holder&rsquo;s transactional

may choose in its sole discretion. The maturity date for each tranche funded shall be six (6) months from the effective date of
each payment (the &ldquo;Maturity Date&rdquo;), and is the date upon which the principal sum, as well as any accrued and unpaid
interest and other fees for each tranche, shall be due and payable. This Note may not be repaid in whole or in part except as
otherwise explicitly set forth herein. Any amount of principal or interest on this Note, which is not paid by the Maturity Date,
shall bear interest at the rate of the lesser of (i) eighteen percent (18%) per annum or (ii) the maximum amount allowed by law,
from the due date thereof until the same is paid (&ldquo;Default Interest&rdquo;). Interest shall commence accruing on the date
that the Note is fully paid and shall be computed on the basis of a 365-day year and the actual number of days elapsed. All payments
due hereunder (to the extent not converted into the Borrower&rsquo;s common stock (the &ldquo;Common Stock&rdquo;) in accordance
with the terms hereof) shall be made in lawful money of the United States of America. All payments shall be made at such address
as the Holder shall hereafter give to the Borrower by written notice made in accordance with the provisions of this Note. Whenever
any amount expressed to be due by the terms of this Note is due on any day which is not a business day, the same shall instead
be due on the next succeeding day which is a business day and, in the case of any interest payment date which is not the date
on which this Note is paid in full, the extension of the due date thereof shall not be taken into account for purposes of determining
the amount of interest due on such date. As used in this Note, the term &ldquo;business day&rdquo; shall mean any day other than

the occurrence of any Event of Default, the Holder shall have the right at any time to convert all or any part of the Default
Amount into fully paid and non-assessable shares of Common Stock of the Borrower at a price per share equal to 70% multiplied
by the lowest VWAP of the common stock during the twenty (20) Trading Day (as defined herein) period ending, in Holder&rsquo;s
sole discretion on each conversion, on either (i) the last complete Trading Day prior to the conversion date (each a &ldquo;Conversion
Date&rdquo;) or (ii) the Conversion Date (subject to adjustment as provided in this Note) (the &ldquo;Conversion Price&rdquo;).
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 the Notes 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 shares of Common Stock 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 outstanding shares of Common Stock. For purposes of the proviso to 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 &ldquo;Exchange Act&rdquo;), and Regulations 13D-G thereunder, except as otherwise provided in clause (1)
of such proviso. &ldquo;Trading Day&rdquo; shall mean any day on which the Common Stock is tradable for any period on the principal
securities exchange or other securities market on which the Common Stock is then being traded. All expenses incurred by Holder
for the issuance and clearing of the Common Stock into which this Note is convertible into shall immediately and automatically
be added to the balance of the Note at such time as the expenses are incurred by Holder. If, at any time when the Note is issued
and outstanding, the Borrower issues or sells, or is deemed to have issued or sold, any shares of Common Stock for a consideration
per share less than the Conversion Price in effect on the date of such issuance (or deemed issuance) of such shares of Common
Stock (a &ldquo;Dilutive Issuance&rdquo;), then the Holder shall have the right, in Holder&rsquo;s sole discretion on each conversion
after such Dilutive Issuance, to utilize the price per share of the Dilutive Issuance as the Conversion Price for such conversion.
The Borrower is required at all times to have authorized and reserved three times the number of shares that is actually issuable
upon full conversion of the Note (based on the Conversion Price of the Note as if an Event of Default under the Note has occurred,
even if an Event of Default has not occurred) (the &ldquo;Reserved Amount&rdquo;). Upon receipt by the Borrower from the Holder
of a facsimile transmission or e-mail (or other reasonable means of communication) of a notice of conversion in the form attached
hereto as Exhibit A (the &ldquo;Notice of Conversion&rdquo;), the Borrower shall issue and deliver or cause to be issued and delivered
to or upon the order of the Holder the Common Stock issuable upon such conversion within two (2) business days after such receipt
(the &ldquo;Deadline&rdquo;). Without in any way limiting the Holder&rsquo;s right to pursue other remedies, including actual
damages and/or equitable relief, the parties agree that if delivery of the Common Stock issuable upon conversion of this Note
is not delivered by the Deadline, the Borrower shall pay to the Holder $3,000 per day in cash, for each day beyond the Deadline
that the Borrower fails to deliver such Common Stock. Until such time as the shares of Common Stock issuable upon conversion of
this Note have been registered under the Act or otherwise may be sold pursuant to Rule 144 or other available exemption, the Common
Stock issuable upon conversion of this Note shall bear a restrictive legend in form, substance, and scope customary for such legends.
Notwithstanding anything in this Note to the contrary, and in addition to the beneficial ownership limitations provided herein,
the total number of shares of Common Stock that may be issued under this Note and that certain Common Stock Purchase Warrant issued
to Holder by Borrower on or about the date hereof for the initial amount of 68,257 shares of Common Stock (the &ldquo;Warrant&rdquo;),
shall be limited to 19.99% of the Borrower&rsquo;s outstanding shares of Common Stock as of the date hereof (the &ldquo;Exchange
Cap&rdquo;), unless stockholder approval is obtained to issue more than the Exchange Cap. The Exchange Cap shall be appropriately
adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction.</FONT></P>

does enter into, or makes any issuance of Common Stock related to a 3(a)(9) Transaction while this Note is outstanding, a liquidated
damages charge of 25% of the outstanding principal balance of this Note, but not less than $15,000, will be assessed and will

but not limited to the issuance of new promissory notes or of a replacement promissory note), or Section 3(a)(10) Transaction
(as defined herein), in which any 3rd party has the right to convert monies owed to that 3rd party (or receive shares pursuant
to a settlement or otherwise) at a discount to market greater than the Conversion Price in effect at that time (prior to all other
applicable adjustments in the Note), then the Conversion Price shall be adjusted at the option of the Holder to such greater discount

shall give written notice to the Holder, with the adjusted Conversion Price and/or adjusted look back period (each adjustment
that is applicable due to the triggering event), within one (1) business day of an event that requires any adjustment described
in the two immediately preceding sentences, and the Holder shall have the sole discretion in determining whether to utilize the
adjusted term pursuant to this section. So long as this Note is outstanding, if any security of the Borrower contains any term
more favorable to the holder of such security or with a term in favor of the holder of such security that was not similarly provided
to the Holder in this Note, then the Borrower shall notify the Holder of such additional or more favorable term and such term,
at Holder&rsquo;s option, shall become a part of the transaction documents with the Holder. The foregoing provision shall not
be applicable to securities issued or to be issued by the Borrower pursuant to the terms of the Senior Secured Convertible Promissory
Notes issued to MEF I, LP and Anson Investments Masterfund LP, each dated January 3, 2018.</FONT></P>

without the requirement for the Company to be in compliance with the current public information required under Rule 144 and without
volume or manner-of-sale restrictions or (c) following the six (6) month anniversary of (I) the issuance date of a New Warrant

month anniversary set forth above and the one (1) year anniversary of the issuance date of any New Warrants, the Company shall
promptly provide notice to the Holder and the Holder undertakes not to sell such New Warrant Shares pursuant to Rule 144 until
the Company notifies the Holder that it has regained compliance with the Current Public Information Requirement; and <U>provided</U>,
<U>further</U>, that if a delegending is in effect solely as the result of the effectiveness of a registration statement covering
the resale of any New Warrant Shares, the Holder undertakes not to sell any such New Warrant Shares if the Holder is notified
or otherwise becomes aware that such registration statement has been withdrawn or suspended, contains a material misstatement
or omission or has become stale. The Holder agrees with the Company that the Holder will sell or transfer any New Warrants or
New Warrant Shares pursuant to either the registration requirements of the Securities Act, including any applicable prospectus
delivery requirements, or an exemption therefrom, and that if such securities are sold pursuant to a registration statement, they
will be sold in compliance with the plan of distribution set forth therein, and acknowledges that the removal of the restrictive
legend from certificates representing any such securities as set forth in this Section 3.2 or otherwise is predicated upon the
Company&rsquo;s reliance upon this understanding.</FONT></P>
