<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">This prospectus relates to our distribution to holders
of our common stock, Series B Preferred Stock, Series C Preferred Stock and certain outstanding warrants, which we refer to as the Participating
Warrants, at no charge, non-transferable subscription rights to purchase units. Each unit, which we refer to as a Unit, consists of (i)
one share of Series D Convertible Preferred Stock, which we refer to as the Preferred Stock, and, based on the Estimated Conversion
Price (as defined below), (ii) 2,713 common stock purchase warrants expiring five years from the date of issuance, which we
refer to as the Class A Warrants, and (iii) 2,713 common stock purchase warrants expiring three years from the date of issuance,
which we refer to as the Class B Warrants and, together with the Class A Warrants, the Warrants. The actual number of Class
A Warrants included in each Unit will be calculated as the quotient obtained by dividing $1,000 by the Conversion Price. The actual number
of Class B Warrants included in each Unit will be calculated as the quotient obtained by dividing $1,000 by the Conversion Price.
Each share of Preferred Stock is convertible, at the option of the holder at any time, into a number of shares of our common stock equal
to the quotient of the stated value of the Preferred Stock ($1,000) divided by the Conversion Price (initially, the Conversion Price
will be equal to 90% of the lowest closing price for a share of our common stock as quoted on the Nasdaq Capital Market, during the five
(5) trading days prior to the expiration of the Subscription Period (including the last day of the Subscription Period). Each Warrant
will be exercisable for one share of our common stock at an exercise price per share equal to the Conversion Price. For purposes of this
preliminary prospectus, we have assumed an estimated Conversion Price of $0.36864 which is equal to 90% of the closing price of
our common stock on September 19, 2022 (the &ldquo;Estimated Conversion Price&rdquo;). As noted elsewhere in this prospectus,
the Estimated Conversion Price is subject to change when calculated on the expiration date of this offering.</P>

Stock, and Participating Warrants, will also receive subscription rights pursuant to the terms of those Series B Preferred Stock, Series
C Preferred Stock, and Participating Warrants.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">SINTX Technologies is a 25-year-old advanced materials
company formed in December 1996, that develops and commercializes advanced ceramics for biomedical, industrial, and antipathogenic
applications. We have grown from focusing primarily on the research, development and commercialization of medical devices manufactured
with silicon nitride to becoming an advanced ceramics company engaged in diverse fields, including biomedical, industrial and antipathogenic
applications. This diversification enables us to focus on our core competencies which are the manufacturing, research, and development
of products comprised from advanced ceramic materials for external partners. We seek to connect with new customers, partners and manufacturers
to help them realize the goal of leveraging our expertise in advanced ceramics to create new, innovative products across these sectors.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white"><B>Biomedical Applications:
</B>Since its inception, SINTX has been focused on medical grade silicon nitride. SINTX silicon nitride products are biocompatible,
bioactive, antipathogenic, and have shown superb bone affinity. Spinal implants made from SINTX silicon nitride have been successfully
implanted in humans since 2008 in the US, Europe, Brazil, and Taiwan. This established use, along with its inherent resistance to bacterial
adhesion and bone affinity &ndash; mean that it may also be suitable in other fusion device applications such as hip, knee
and dental implants. Bacterial infection of any biomaterial implants is always a concern. SINTX silicon nitride is inherently
resistant to bacterial colonization and biofilm formation, making it antibacterial. SINTX silicon nitride products can be polished
to a smooth and wear-resistant surface for articulating applications, such as bearings for hip and knee replacements.</P>
<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">&nbsp;</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">We
believe that silicon nitride has a superb combination of properties that make it suited for long-term human implantation. Other biomaterials
are based on bone grafts, metal alloys, and polymers- all of which have well-known practical limitations and disadvantages. 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 and viral infection, ease of diagnostic imaging, resistance to corrosion, and superior
strength and fracture resistance, among other advantages, all of which claims are validated in our large and growing inventory
of peer-reviewed, published literature reports. 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.</FONT></P>

Assessment and Transfer, Inc. (TA&amp;T). TA&amp;T is a nearly 40-year-old business, and TA&amp;T&rsquo;s mission is to transition advanced
materials and process technologies from a laboratory environment to commercial products and services. TA&amp;T has supplied ceramics
for use in several biomedical applications. These products were made via 3D printing and include components for surgical instruments
as well as conceptual and prototype dental implants.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white"><B>Industrial Applications:
</B>It is the belief of SINTX that its silicon nitride has the best combination of mechanical, thermal, and electrical
properties of any technical ceramic material. It is a high-performance technical ceramic with high strength, toughness, and hardness,
and is extremely resistant to thermal shock and impact. It is also an electrically insulating ceramic material. Typically, it is used
in applications where high load-bearing capacity, thermal stability, and wear resistance are required. The Company has obtained
AS9100D certification and ITAR registration to facilitate entry into the aerospace portion of this market.</P>

the ceramic armor market through the purchase of assets from B4C, LLC and a technology partnership with Precision Ceramics USA. SINTX
intends to develop and manufacture high-performance ceramics for personnel, aircraft, and vehicle armor including a 100% Boron Carbide
material for ultimate lightweight performance in ballistic applications, and a composite material made of Boron Carbide and Silicon Carbide
for exceptional multi-hit performance against ballistic threats. SINTX has signed a 10-year lease at a building near its
headquarters in Salt Lake City, UT to house development and manufacturing activities for SINTX Armor.</P>

Applications:</B> Today, there is a global need to improve protection against pathogens in everyday life. SINTX believes that by
incorporating its unique composition of silicon nitride antipathogenic powder into products such as face masks, filters, and wound care
devices, it is possible to manufacture surfaces that inactivate pathogens, thereby limiting the spread of infection and disease. The
discovery in 2020 that SINTX silicon nitride inactivates SARS-CoV-2, the virus which causes the disease COVID-19, has opened new
markets and applications for our material and we have refocused many of our resources on these opportunities.</FONT></P>

    expiration of the Subscription Period (including the last day of the Subscription Period), subject to adjustment (the &ldquo;Conversion

    is equal to 90% of the closing price of our common stock on September 19, 2022 (the &ldquo;Estimated Conversion Price&rdquo;).
    Based on the Estimated Conversion Price, the Preferred Stock included in the Units would be initially convertible into an aggregate
    of 27,130,000 shares of common stock. The actual number of shares that the Preferred Stock may be converted into will depend
    on the Conversion Price determined on the expiration date. Because the actual Conversion Price will be determined on the expiration
    date, rights holders will not know the Conversion Price, nor will they know the number of shares of common stock underlying the Preferred

Preferred Stock and, based on the Estimated Conversion Price, 5,426 warrants to purchase common stock, at a subscription price

convertible into shares of our common stock at a conversion price equal to the Conversion Price determined on the expiration date. Each
Class A Warrant entitles you to purchase one share of common stock at a per share exercise price equal to the Conversion Price,

one share of common stock at a per share exercise price equal to the Conversion Price, from the date of issuance through its expiration
three years after the date of issuance. The Preferred Stock do not generally have any voting rights and will not be certificated.
The shares of Preferred Stock and warrants that comprise each Unit are immediately separable and will be issued separately in this Rights

Each Subscription Right entitles the record holder to a Basic Subscription Right and an Over-Subscription Privilege. The Subscription

our prospects for the future, the terms of the Rights Offering, the information in this prospectus and the other considerations relevant

to buy shares of our common stock at a price greater than the prevailing market price. We cannot predict the effect, if any, that the
availability of shares for future sale represented by the Warrants issued in connection with the Rights Offering will have on the market
price of our common stock from time to time. Further, if a substantial number of Subscription Rights are exercised and the holders of
the shares received upon exercise of those Subscription Rights or the related Warrants choose to sell some or all of the shares underlying
the Subscription Rights or the related Warrants, the resulting sales could depress the market price of our common stock.</FONT></P>

convertible preferred stock convertible into an aggregate of 19,306 shares of common stock and warrants issued in May 2018 that are exercisable
for an aggregate of 310,585 shares of common stock. The Series B convertible preferred stock and May 2018 warrants contain full-ratchet
anti-dilution provisions which, subject to limited exceptions, would reduce the conversion price of the Series B preferred stock (and
increase the number of shares issuable under the Series B preferred stock) and reduce the exercise price of the May 2018 warrants in
the event that we in the future issue common stock, or securities convertible into or exercisable to purchase common stock, at a price
per share lower than the conversion price or exercise price then in effect. Our outstanding 26 shares of Series B preferred stock are,
prior to this offering, convertible into 19,306&nbsp;shares of Common Stock at a conversion price of $1.4814 per share. The May 2018
warrants currently are exercisable at an exercise price of $1.4814 per share. These full ratchet anti-dilution provisions will likely
be triggered by the issuance of the Preferred Stock and the Warrants in the Rights Offering.</FONT></P>

believe the distribution of the Subscription Rights in this Rights Offering should be a non-taxable distribution to holders of shares
of common stock, Series B Preferred Stock, Series C Preferred Stock, and holders of Participating Warrants, under Section 305(a) of the
Internal Revenue Code of 1986, as amended, or the Code. Please see the discussion under the heading &ldquo;Material U.S. Federal Income
Tax Consequences&rdquo; below. This position is not binding on the IRS, or the courts, however. If this Rights Offering is deemed to
be part of a &ldquo;disproportionate distribution&rdquo; under Section 305 of the Code, your receipt of Subscription Rights in this Rights
Offering may be treated as the receipt of a taxable distribution to you equal to the fair market value of the Subscription Rights.
Any such distribution would be treated as dividend income to the extent of our current and accumulated earnings and profits, if any,
with any excess being treated as a return of capital to the extent thereof and then as capital gain. Each holder of shares of common
stock or Preferred Stock and each holder of Participating Warrants is urged to consult his, her or its own tax advisor with respect
to the particular tax consequences of this Rights Offering.</FONT></P>

are distributing to the record holders of our common stock, Series B Preferred Stock, Series C Preferred Stock and Participating Warrants,
at no charge, non-transferable Subscription Rights to purchase one Unit at a subscription price of $1,000 per Unit. Each Basic Subscription
Right will entitle you to purchase one share of our preferred stock and, based on the Estimated Conversion Price, 5,426 Warrants.
Each share of Preferred Stock will be convertible at the option of the holder at any time, into the number of shares of our common stock
determined by dividing the $1,000 stated value per share of the Preferred Stock by the Conversion Price determined on the expiration
date. Based on the Estimated Conversion Price, the Preferred Stock included in the Units would be initially convertible into an aggregate
of 27,130,000 shares of common stock. The actual number of shares that the Preferred Stock may be converted into will depend on
the Conversion Price determined on the expiration date. Each Class A Warrant will be exercisable for one share of our common stock
at a per share exercise price equal to the Conversion Price from the date of issuance through the expiration five years from the date
of issuance. Each Class B Warrant will be exercisable for one share of our common stock at a per share exercise price equal to the
Conversion Price from the date of issuance through the expiration three years from the date of issuance. Based on the Estimated Conversion
Price, the Warrants included in the Units would be initially exercisable for an aggregate of 54,260,000 shares of common stock.
The actual number of shares that the Warrants may be exercised for will depend on the Conversion Price determined on the expiration date.
The actual number of Class A Warrants included in each Unit will be calculated as the quotient obtained by dividing $1,000 by the
Conversion Price. The actual number of Class B Warrants included in each Unit will be calculated as the quotient obtained by dividing
$1,000 by the Conversion Price. </FONT></P>

the authorities governing transactions such as this Rights Offering are complex and do not speak directly to the consequences of certain
aspects of this Rights Offering, including the inclusion of the right to purchase Warrants in the Subscription Rights (rather than the
right to purchase only shares of our Preferred Stock), the distribution of Subscription Rights to holders of Participating Warrants and
the effects of the Over-Subscription Privilege, we do not believe a U.S. holder&rsquo;s receipt of Subscription Rights pursuant to the
Rights Offering should be treated as a taxable distribution with respect to its existing shares of common stock, Series B Preferred Stock,
Series C Preferred Stock or Participating Warrants, as applicable, for U.S. federal income tax purposes. Section 305(a) of the Code generally
provides that the receipt by a stockholder, or a holder of rights to acquire stock, of a right to acquire stock or warrants is not included
in the taxable income of the stockholder; however, the general non-recognition rule in Section 305(a) of the Code is subject to exceptions
described in Section 305(b) of the Code, which include &ldquo;disproportionate distributions.&rdquo; A disproportionate distribution
is generally a distribution or a series of distributions, including deemed distributions, that has the effect of the receipt of cash
or other property by some stockholders (including holders of rights to acquire stock and holders of debt instruments convertible into
stock) and an increase in the proportionate interest of other stockholders (including holders of rights to acquire stock and holders
of debt instruments convertible into stock) in a corporation&rsquo;s assets or earnings and profits. <B>During the last 36 months, we
have not made any distributions of cash or property (other than stock or rights to acquire stock) with respect to: (i) our common stock

(other than stock or rights to acquire stock) with respect to: (i) our common stock or (ii) options or warrants to acquire our common
stock; however, there is no guarantee that we will not make such distributions in the future. In addition, we do not currently have any

position regarding the non-taxable treatment of the Subscription Right distribution is not binding on the IRS, or the courts. If this

cash or property (other than stock or rights to acquire stock) are made with respect to our common stock, options or warrants, because
the issuance of the Subscription Rights is a &ldquo;disproportionate distribution&rdquo; or otherwise, the fair market value of the Subscription
Rights would be taxable to U.S. holders of our common stock as a dividend to the extent of the U.S. holder&rsquo;s pro rata share of
our current and accumulated earnings and profits, if any, with any excess being treated as a return of capital to the extent thereof
and then as capital gain. <B>Although no assurance can be given, we anticipate that we will not have current and accumulated earnings

price of each Warrant that may be received upon exercise of a Subscription Right is not yet determinable. The tax authorities that apply
to warrants with an exercise price less than the fair market value of the underlying security which will be received upon exercise thereof
are complex and subject to differing interpretations. Accordingly, the tax treatment of the Warrants which may be received upon exercise
of a Subscription Right is uncertain. If the exercise price of a Warrant as of the date of receipt by a U.S. holder that exercises a
Subscription Right is substantially less than the fair market value of the underlying share of our common stock which may be received
upon exercise of such Warrant, the Warrant may be classified for U.S. federal income tax purposes as of the date of receipt by a U.S.
holder as a share of our common stock. If a Warrant is properly classified as a share of common stock for U.S. federal income tax purposes,
a U.S. holder will not be required to recognize income, gain or loss upon exercise of such Warrant and a U.S. holder&rsquo;s tax basis
in a share of our common stock will be equal to the sum of (1) the U.S. holder&rsquo;s tax basis in the Warrants exchanged therefor and
(2) the exercise price of such Warrants. A U.S. holder&rsquo;s holding period in the shares of our common stock received upon exercise
should generally include the holding period of such U.S. holder in the Warrants. For the U.S. federal income tax consequences of a sale
or other taxable disposition (other than by exercise), or distributions (including constructive distributions) paid on the Warrants if
they are properly classified as shares of our common stock for U.S. federal income tax purposes, see the discussions below under the

Warrants received upon exercise of a Subscription Right, we were to pay a taxable dividend to our stockholders and, in accordance with

the payment of a taxable dividend to a U.S. holder of the Warrants to the extent of our earnings and profits, notwithstanding the fact
that such holder will not receive a cash payment. If the exercise price is adjusted in certain other circumstances (or in certain circumstances,
there is a failure to make appropriate adjustments), or there is an adjustment to the number of common shares that will be issued on

foreign entities&rdquo; (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain
payments to non-compliant foreign financial institutions and certain other account holders. Non-U.S. holders typically will be required
to furnish certifications (generally on the applicable IRS Form W-8) or other documentation to provide the information required by FATCA
or to establish compliance with or an exemption from withholding under FATCA. FATCA withholding may apply where payments are made through
a non-U.S. intermediary that is not FATCA compliant, even where the non-U.S. holder satisfies the holder&rsquo;s own FATCA obligations.
Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA
may be subject to different rules.</FONT></P>

under FATCA also potentially applies to payments of gross proceeds from the sale or other disposition of our common stock. Proposed regulations,
however, would eliminate withholding under FATCA on such payments, and the U.S. Treasury Department has indicated that taxpayers may
rely on this aspect of the proposed regulations until final regulations are issued. Because we may not know the extent to which a distribution
is a dividend for U.S. federal income tax purposes at the time it is made, for purposes of these withholding rules we or the applicable
withholding agent may treat the entire distribution as a dividend. Prospective investors should consult their own tax advisors regarding
the potential application of these withholding provisions.</FONT></P>

common stock purchase warrants outstanding, which expire between December 2022 and February 2025. Each of these warrants entitles
the holder to purchase one share of common stock at prices ranging between $278,370 and $1.4814, as converted, per share, with a weighted
average exercise price of $6.07 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 amount 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 and reclassifications and consolidations. Certain 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.</P>

provisions of (1) Delaware law, (2) our Restated Certificate of Incorporation and (3) our Restated Bylaws discussed below could discourage
or make it more difficult to prevail in a proxy contest or effect other change in our management or the acquisition of control by a holder
of a substantial amount of our voting stock. It is possible that these provisions could make it more difficult to accomplish, or could
deter, transactions that stockholders may otherwise consider to be in their best interests or our best interests. These provisions are
intended to enhance the likelihood of continuity and stability in the composition of our board of directors and in the policies formulated
by the board of directors and to discourage certain types of transactions that may involve an actual or threatened change in control
of our company. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. These provisions also
are intended to discourage certain tactics that may be used in proxy fights. These provisions also may have the effect of preventing
changes in our management.</FONT></P>

Statutory Business Combinations Provision. </I>We are subject to the anti-takeover provisions of Section 203 of the Delaware General

with an &ldquo;interested stockholder&rdquo; for a period of three years after the date of the transaction in which the person became
an interested stockholder, unless the business combination is, or the transaction in which the person became an interested stockholder
was, approved in a prescribed manner or another prescribed exception applies. For purposes of Section 203, a &ldquo;business combination&rdquo;
is defined broadly to include a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholder,
and, subject to certain exceptions, an &ldquo;interested stockholder&rdquo; is a person who, together with his or her affiliates and
associates, owns (or within three years prior, did own) 15% or more of the corporation&rsquo;s voting stock.</FONT></P>

Board of Directors; Appointment of Directors to Fill Vacancies; Removal of Directors for Cause. </I>Our Restated Certificate of Incorporation

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 80% 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>

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

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

voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences of each series of preferred stock,
all to the fullest extent permissible under the Delaware General Corporation Law and subject to any limitations set forth in our certificate

applicable to such preferred stock is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred
stock, while providing desirable flexibility in connection with possible financings, acquisitions and other corporate purposes, could
have the effect of making it more difficult for a third-party to acquire, or could discourage a third-party from acquiring, a majority

connection with this Rights Offering, we have agreed to pay fees to Maxim Group LLC as dealer-manager an aggregate cash fee equal to
7.0% of the gross proceeds received by us directly from exercises of the Subscription Rights. We advanced $20,000 (the &ldquo;Advance&rdquo;)
to Maxim Group LLC as an advance against the expense allowance upon their engagement as dealer-manager and agreed to reimburse the reasonable
fees and expenses of the dealer-manager up to $100,000 (including the Advance). Any portion of the Advance not used for Maxim&rsquo;s
actual out-of-pocket expenses shall be promptly reimbursed to us. Additionally, we agreed to grant to Maxim (or its designated affiliates)
share purchase warrants (the &ldquo;Dealer Warrants&rdquo;) covering a number of shares of our common stock equal to 4.0% of the common
stock issuable upon exercise of the Preferred Stock sold in the Rights Offering. In the event that we engage Ascendiant Capital Markets,
LLC as a financial advisor in connection with the Offering, Maxim agrees that Ascendiant shall be entitled to 15% of the total fee earned
by Maxim under the dealer-management agreement and 15% of the Dealer Warrants issuable upon Closing (i.e., Maxim will receive 85% of
the cash fee and Dealer Warrants, and Ascendiant shall receive 15% of the cash fee and Dealer Warrants). The Dealer Warrants will be
non-exercisable for six (6) months after the date of the Closing and will expire five years after the commencement of sales of the offering.
The Dealer Warrants will be exercisable at a price equal to 110.0% of the conversion price of the Convertible Preferred. The Warrants
shall not be redeemable. The Dealer Warrants may not be sold, transferred, assigned, pledged or hypothecated or be the subject of
any hedging, short sale, derivative, put, or call transaction that would result in the effective economic disposition of the securities
for a period of 180 days beginning on the date of the commencement of sales of the offering, except that they may be assigned, in
whole or in part, to any officer or partner, registered person or affiliate of Maxim (or to Ascendiant) subject to the terms

as to which they could be indemnified. The Registrant also intends to enter into indemnification agreements with its future directors

The Company has duly and properly filed or caused to be filed with the U. S. Patent and Trademark Office (the &ldquo;<B>PTO</B>&rdquo;)
and applicable foreign and international patent authorities all patent applications owned by the Company, its Subsidiaries or Affiliates
(the &ldquo;<B>Company Patent Applications</B>&rdquo;). The product candidates described in the Registration Statement, any Preliminary
Prospectus and the Prospectus as under development by the Company fall within the scope of the claims of one or more patents or patent
applications owned by, or exclusively licensed to, the Company. The Company has complied in all material respects with the PTO&rsquo;s
duty of candor and disclosure for the Company Patent Applications and has made no material misrepresentation in the Company Patent Applications.
The Company Patent Applications disclose patentable subject matters, and the Company has not been notified of any inventorship challenges
nor has any interference been declared or provoked nor is any material fact known by the Company that would preclude the issuance of
patents with respect to the Company Patent Applications or would render such patents invalid or unenforceable. No third party possesses
rights to the Company&rsquo;s Intellectual Property Rights that, if exercised, could enable such party to develop products competitive
to those the Company intends to develop as described in the Prospectus.</FONT></P>

The Company possesses valid and current licenses, registrations, certificates, permits and other authorizations issued by the appropriate
foreign, federal, state or local regulatory authorities as necessary to conduct its respective businesses (collectively, the &ldquo;<B>Licensing

a Licensing Requirement would not have a Material Adverse Effect. The Company has not received any notice of proceedings relating to
the revocation or modification of, or noncompliance with, any such license, certificate, permit or authorization, which could result
in a Material Adverse Effect. No action, suit or proceeding, other than routine audits, by or before any court or Governmental Authority

any pending audit is reasonably likely to result in the removal, revocation, suspension or other termination of the Company&rsquo;s authority
to operate under the Licensing Requirements.</FONT></P>

The studies and tests conducted or sponsored by or on behalf of the Company (the &ldquo;<B>Studies and Tests</B>&rdquo;) that are described
or referred to in any Preliminary Prospectus, the Prospectus and the Registration Statement were and, if still pending, are being conducted
in accordance with experimental protocols, procedures and controls pursuant to accepted professional scientific standards and all Applicable
Laws and Authorizations; the descriptions of the results of such studies, tests and trials contained in any Preliminary Prospectus, the
Prospectus and the Registration Statement are accurate and complete in all material respects and fairly present the data derived from
such studies, tests and trials. The Company is not aware of any studies or tests, the results of which the Company believes reasonably
call into question the study or test described or referred to in any Preliminary Prospectus, the Prospectus and the Registration Statement
when viewed in the context in which such results are described. The Company has not received any notices or correspondence with the FDA,
the EMA, the ANVISA and the ADH or any foreign, state or local governmental body exercising comparable authority suggesting or requiring
a clinical hold, termination, suspension or material modification of the Studies and Tests and that such clinical hold, termination,
suspension or material modification would reasonably be expected to have a Material Adverse Effect, and, to the Company&rsquo;s knowledge
after reasonable investigation, there are no reasonable grounds for the same. The Company has obtained (or caused to be obtained) informed
consent by or on behalf of each human subject who participated in Studies and Tests. In using or disclosing patient information received
by the Company in connection with the Studies and Tests, the Company has complied in all material respects with all applicable laws and
regulatory rules, including, without limitation, the Health Insurance Portability and Accountability Act of 1996 and the rules and regulations
thereunder. To the Company&rsquo;s knowledge after reasonable investigation, none of the Studies and Tests involved any investigator
who has been disqualified as a clinical investigator or has been found by the FDA, EMA, ANVISA or ADH to have engaged in scientific misconduct
or debarred or excluded from participation in any governmental health care payment program. There has not been any violation of applicable
law or regulation by the Company in its product development efforts, submissions or reports to any regulatory authority that could reasonably
be expected to require investigation, corrective action or enforcement action, except where such violation would not, singly or in the
aggregate, result in a Material Adverse Effect.</FONT></P>

If any lawsuit, claim or proceeding is brought against any indemnified party in respect of which indemnification may be sought against
the indemnifying party pursuant to this Section 11, such indemnified party shall promptly notify the indemnifying party of the commencement
of such lawsuit, claim or proceeding; provided, however, that the failure so to notify the indemnifying party shall not relieve the indemnifying
party from any obligation or liability which it may have under this Section 11 except to the extent that it has been prejudiced in any
material respect by such failure and in any event shall not relieve the indemnifying party from any other obligation or liability which
it may have to such indemnified party otherwise than under this Section 11. In case any such lawsuit, claim or proceeding shall be brought
against any indemnified party and such indemnified party shall notify the indemnifying party of the commencement of such lawsuit, claim
or proceeding, the indemnifying party shall be entitled to participate in such lawsuit, claim or proceeding, and, after written notice
from the indemnifying party to such indemnified party, to assume the defense of such lawsuit, claim or proceeding with counsel of its
choice at its expense; provided, however, that such counsel shall be satisfactory to the indemnified party in the exercise of its reasonable
judgment. Notwithstanding the election of the indemnifying party to assume the defense of such lawsuit, claim or proceeding, such indemnified
party shall have the right to employ separate counsel and to participate in the defense of such lawsuit, claim or proceeding, and the
indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel (and shall pay such reasonable fees, costs
and expenses promptly after receipt of any invoice therefor) if: (i) the use of counsel chosen by the indemnifying party to represent
such indemnified party would present such counsel with a conflict of interest; (ii) the defendants in, or targets of, any such lawsuit,
claim or proceeding include both an indemnified party and the indemnifying party, and such indemnified party shall have reasonably concluded
that there may be legal defenses available to it or to other indemnified parties which are different from or in addition to those available
to the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf
of the indemnified party); (iii) the indemnifying party shall not have employed counsel satisfactory to such indemnified party, in the
exercise of such indemnified party&rsquo;s reasonable judgment, to represent such indemnified party within a reasonable time after notice
of the institution of any such lawsuit, claim or proceeding; or (iv) the indemnifying party shall authorize such indemnified party to
employ separate counsel at the expense of the indemnifying party. The foregoing indemnification commitments shall apply whether or not
the indemnified party is a formal party to any such lawsuit, claim or proceeding. The indemnifying party shall not be liable for any
settlement of any lawsuit, claim or proceeding effected without its consent (which consent will not be unreasonably withheld), but if
settled with such consent, the indemnifying party agrees, subject to the provisions of this Section 11, to indemnify the indemnified
party from and against any loss, damage or liability by reason of such settlement. The Company agrees to notify Maxim promptly, or cause
Maxim to be notified promptly, of the assertion of any lawsuit, claim or proceeding against the Company, any of its officers or directors
or any Person who controls any of the foregoing within the meaning of Section 20(a) of the Exchange Act, arising out of or relating the
Rights Offering. The Company further agrees that any settlement of a lawsuit, claim or proceeding against it arising out of Rights Offering

affiliates, and any officer, director, employee or agent of Maxim, and any Person controlling (within the meaning of Section 20(a) of

In order to provide for contribution in circumstances in which the indemnification provided for in this Section 11 for any reason held
to be unavailable from any indemnifying party or is insufficient to hold harmless a party indemnified thereunder, the Company, on the
one hand, and Maxim, on the other hand, shall contribute to the aggregate losses, claims, damages, liabilities and expenses of the nature
contemplated by such indemnification provision (including any investigation, legal and other expenses incurred in connection with, and
any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting in the case of losses, claims,
damages, liabilities and expenses suffered by the Company, any contribution received by the Company from Persons, other than Maxim, who
may also be liable for contribution, including Persons who control the Company within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act, officers of the Company who signed the Registration Statement and directors of the Company) as incurred
to which the Company and Maxim may be subject, in such proportions as is appropriate to reflect the relative benefits received by the
Company, on the one hand, and Maxim, on the other hand, from the Rights Offering or, if such allocation is not permitted by applicable
law, in such proportions as are appropriate to reflect not only the relative benefits referred to above but also the relative fault of
the Company, on the one hand, and Maxim, on the other hand, in connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the
Company, on the one hand, and Maxim, on the other hand, shall be deemed to be in the same proportion as: (x) the total proceeds from
the Rights Offering (net of the fees of the Dealer-Manager set forth in Section 6 hereof, but before deducting expenses) received by
the Company bears to (y) the respective fees of the Dealer-Manager set forth and allocated in Section 6 hereof actually received by the
Dealer-Manager. The relative fault of each of the Company, on the one hand, and Maxim, on the other hand, shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or Maxim (which consists solely and exclusively of the Dealer-Manager
Information) and the parties&rsquo; relative intent, knowledge, access to information and opportunity to correct or prevent such statement
or omission. The Company and the Dealer-Manager agree that it would not be just and equitable if contribution pursuant to this Section
11(f) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations
referred to above in this Section. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified
party and referred to above in this Section 11 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any judicial, regulatory
or other legal or governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged
untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 11: (i) no Dealer-Manager shall be required
to contribute any amount in excess of the fees actually received by such Dealer-Manager from the Company in connection with the Rights
Offering and (ii) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall
be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 11,
each Person controlling the Dealer-Manager within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall
have the same rights to contribution as such Dealer-Manager, and each Person, if any, who controls the Company within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, each officer of the Company who shall have signed the Registration
Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to clauses
(i) and (ii) of the immediately preceding sentence. Any party entitled to contribution will, promptly after receipt of notice of commencement
of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or
parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall
not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 11(f)
or otherwise.</FONT></P>

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; <U>provided</U>, <U>however</U>, 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 6(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>

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 6(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 6(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 Conversion Shares upon conversion of the shares of Preferred

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 6(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 6(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 6(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 (which may be via email) 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 Limitation</U>&rdquo; shall be 4.99% (or, upon election by a Holder prior to the
issuance of any shares of Preferred Stock, 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 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 6(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 6(d) shall continue to apply. Any such increase in the Beneficial Ownership Limitation will not be
effective until the 61<SUP>st</SUP> 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 6(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>

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 conversion of this Preferred Stock following such Fundamental Transaction.
The amount of any consideration to be received by a Holder in connection with a Fundamental Transaction shall be payable in 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 Corporation
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. To the extent necessary to effectuate the foregoing provisions, any successor to the Corporation or surviving
entity in such Fundamental Transaction shall file a new Certificate of Designation with the same terms and conditions and issue to the
Holders new preferred stock consistent with the foregoing provisions and evidencing the Holders&rsquo; right to convert such preferred
stock into Alternate Consideration. The Corporation shall cause any successor entity in a Fundamental Transaction in which the Corporation
is not the survivor (the &ldquo;<U>Successor Entity</U>&rdquo;) to assume in writing all of the obligations of the Corporation under
this Certificate of Designation and the other Transaction Documents in accordance with the provisions of this Section 7(d) pursuant to
written agreements prior to such Fundamental Transaction and shall, at the option of the holder of this Preferred Stock, deliver to the
Holder in exchange for this Preferred Stock a security of 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 from
and after the date of such Fundamental Transaction, the provisions of this Certificate of Designation and the other Transaction Documents
referring to the &ldquo;Corporation&rdquo; shall refer instead to the Successor Entity), and may exercise every right and power of the
Corporation and shall assume all of the obligations of the Corporation under this Certificate of Designation and the other Transaction
Documents with the same effect as if such Successor Entity had been named as the Corporation herein.</FONT></P>

was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common Stock

<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;Attribution Parties&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>

(which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii)
subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split)
outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification of shares of the Common Stock
any shares of capital stock of the Company (each, a &ldquo;<U>Share Combination Event</U>&rdquo;, and such date thereof, the &ldquo;<U>Share

be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the
denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable
upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged.
Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders
entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision,
combination or re-classification. If at any time and from time to time on or after the date of this Warrant there occurs any Share Combination
Event and the Event Market Price (as defined below) is less than the Exercise Price then in effect (after giving effect to the adjustment
in clause 3(a) above), then on the fifth (5th) Trading Day immediately following such Share Combination Event, the Exercise Price then
in effect on such fifth (5th) Trading Day (after giving effect to the adjustment in clause 3(a) above) shall be reduced (but in no event
increased) to the Event Market Price. For the avoidance of doubt, if the adjustment in the immediately preceding sentence would otherwise
result in an increase in the Exercise Price hereunder, no adjustment shall be made. &ldquo;<U>Event Market Price</U>&rdquo; means, with
respect to any Share Combination Event Date, the quotient determined by dividing (x) the sum of the VWAP of the shares of Common Stock
for each of the five (5) Trading Days following such Share Combination Event divided by (y) five (5). All such determinations shall be
appropriately adjusted for any stock dividend, stock split, stock combination, recapitalization or other similar transaction during such

<U>Calculation of Consideration Received</U>. If any Option and/or Convertible Security and/or Adjustment Right is issued in connection

Security&rdquo;, and such Option and/or Convertible Security and/or Adjustment Right, the &ldquo;Secondary Securities&rdquo; and together

if such Primary Security is an Option and/or Convertible Security, 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 Sections 3(b)(i) or 3(b)(ii) above and
(z) the lowest VWAP of the shares of Common Stock on any Trading Day during the five (5) Trading Day period (the &ldquo;<U>Adjustment
Period</U>&rdquo;) 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 principal Trading Market of the Common Stock on a Trading Day, such Trading Day
shall be the first Trading Day in such five Trading Day period and if this Warrant is exercised, on any given Exercise Date during any
such Adjustment Period, solely with respect to such portion of this Warrant converted on such applicable Exercise Date, such applicable
Adjustment Period shall be deemed to have ended on, and included, the Trading Day immediately prior to such Exercise Date). If any shares
of Common Stock, Options or Convertible Securities 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 Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received by
the Company will be the fair value of such consideration, except where such consideration consists of publicly traded securities, in
which case the amount of consideration received by the Company 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 Convertible
Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity,
the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving
entity as is <U>attributable</U> to such shares of Common Stock, Options or Convertible Securities (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>

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), purchase this Warrant from the Holder by paying to the Holder
an amount of cash equal to the Black Scholes Value (as defined below) of the remaining unexercised portion of this Warrant on the date
of the consummation of such Fundamental Transaction; <U>provided</U>, <U>however</U>, 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 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-Scholes Option Pricing Model obtained from the &ldquo;OV&rdquo; function on Bloomberg, L.P. (&ldquo;<U>Bloomberg</U>&rdquo;)
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 (determined utilizing a 365 day annualization factor) 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 greater of (i) the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration,
if any, being offered in such Fundamental Transaction and (ii) the greater of (x) the last VWAP immediately prior to the public announcement
of such Fundamental Transaction and (y) the last VWAP immediately prior to the consummation of 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 and (E) a zero cost of borrow. 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>

In addition to any other rights available to
the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance with 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;Attribution Parties&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>

(which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii)
subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split)
outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification of shares of the Common Stock
any shares of capital stock of the Company (each, a &ldquo;<U>Share Combination Event</U>&rdquo;, and such date thereof, the &ldquo;<U>Share
Combination Event Date</U>&rdquo;), then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall
be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the
denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable
upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged.
Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders
entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision,
combination or re-classification. If at any time and from time to time on or after the date of this Warrant there occurs any Share Combination
Event and the Event Market Price (as defined below) is less than the Exercise Price then in effect (after giving effect to the adjustment
in clause 3(a) above), then on the fifth (5th) Trading Day immediately following such Share Combination Event, the Exercise Price then
in effect on such fifth (5th) Trading Day (after giving effect to the adjustment in clause 3(a) above) shall be reduced (but in no event
increased) to the Event Market Price. For the avoidance of doubt, if the adjustment in the immediately preceding sentence would otherwise
result in an increase in the Exercise Price hereunder, no adjustment shall be made. &ldquo;<U>Event Market Price</U>&rdquo; means, with
respect to any Share Combination Event Date, the quotient determined by dividing (x) the sum of the VWAP of the shares of Common Stock
for each of the five (5) Trading Days following such Share Combination Event divided by (y) five (5). All such determinations shall be
appropriately adjusted for any stock dividend, stock split, stock combination, recapitalization or other similar transaction during such
period.</P>

security for each of the five (5) Trading Days immediately preceding the date of receipt. If any shares of Common Stock, Options or Convertible
Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity,
the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving
entity as is <U>attributable</U> to such shares of Common Stock, Options or Convertible Securities (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>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 Company), (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer,

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

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), purchase this Warrant from the Holder by paying to the Holder
an amount of cash equal to the Black Scholes Value (as defined below) of the remaining unexercised portion of this Warrant on the date
of the consummation of such Fundamental Transaction; <U>provided</U>, <U>however</U>, 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 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-Scholes Option Pricing Model obtained from the &ldquo;OV&rdquo; function on Bloomberg, L.P. (&ldquo;<U>Bloomberg</U>&rdquo;)
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 (determined utilizing a 365 day annualization factor) 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 greater of (i) the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration,
if any, being offered in such Fundamental Transaction and (ii) the greater of (x) the last VWAP immediately prior to the public announcement
of such Fundamental Transaction and (y) the last VWAP immediately prior to the consummation of 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 and (E) a zero cost of borrow. 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>

Upon the Warrant Agent&rsquo;s receipt, at or prior to the Close of Business on the Termination Date set forth in a Warrant, of the executed
Exercise Notice, accompanied by payment of the Exercise Price pursuant to Section 2(a) of the Warrant for the shares to be purchased
(other than in the case of a Cashless Exercise), an amount equal to any applicable tax, governmental charge or expense reimbursement
referred to in Section 6 in cash, or by certified check or bank draft payable to the order of the Company and, in the case of an exercise
of a Warrant in the form of a Warrant Certificate for all of the Warrant Shares represented thereby, the Warrant Certificate, the Warrant
Agent shall cause the Warrant Shares underlying such Warrant to be delivered to or upon the order of the Holder of such Warrant, registered
in such name or names as may be designated by such Holder, no later than the date that is two (2) Trading Days after the date of delivery
of the Exercise Notice (the &ldquo;<U>Warrant Share Delivery Date</U>&rdquo;). If the Company is then a participant in the DWAC system
of the Depositary and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale
of the Warrant Shares by Holder or (B) the Warrant is being exercised via Cashless Exercise, then the certificates for Warrant Shares
shall be transmitted by the Warrant Agent to the Holder by crediting the account of the Holder&rsquo;s broker with the Depositary through
its DWAC system. For the avoidance of doubt, if the Company becomes obligated to pay any amounts to any Holders pursuant to Section 2(d)(i)
or 2(d)(iv) of the Warrant, such obligation shall be solely that of the Company and not that of the Warrant Agent. Notwithstanding anything
else to the contrary in this Agreement, except in the case of a Cashless Exercise, if any Holder fails to duly deliver payment to the
Warrant Agent of an amount equal to the aggregate Exercise Price of the Warrant Shares to be purchased upon exercise of such Holder&rsquo;s
Warrant as set forth in Section 7(a) hereof, the Warrant Agent will not be obligated to deliver certificates representing any such Warrant
Shares (via DWAC or otherwise) until following receipt of such payment, and the applicable Warrant Share Delivery Date shall be deemed
extended by one day for each day (or part thereof) until such payment is delivered to the Warrant Agent.</FONT></P>

mail a notice thereof in writing to the Holders of the Warrant Certificates. However, failure to give any notice provided for in this
Section 17, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Warrant Agent or the
appointment of the successor Warrant Agent, as the case may be.</FONT></P>

personal check may take several business days to clear. Accordingly, if you wish to pay the subscription price by uncertified personal
check, then you should make payment sufficiently in advance of the Expiration Date to ensure its receipt and clearance by that time.
To avoid disappointment caused by a failure of your subscription due to your payment not clearing prior to the Expiration Date, SINTX
urges you to consider payment by means of certified or cashier&rsquo;s check, money order or wire transfer. It is highly recommended
that if you intend to pay the subscription price by personal check, then your subscription payment should be received by the subscription
agent well before the Expiration Date. If your personal check does not clear before the Expiration Date, then you will not receive any
units, and SINTX&rsquo;s only obligation will be to return your subscription payment, without interest or deduction.</FONT></P>

<B>Partial Exercises; Effect of Over- and Under-Payments</B>. If you exercise less than all of the subscription rights evidenced by your
subscription rights certificate, the subscription agent will issue to you a new subscription rights certificate evidencing the unexercised
subscription rights. However, if you choose to have a new subscription rights certificate sent to you, you may not receive any such new
subscription rights certificate in sufficient time to permit exercise of the subscription rights evidenced thereby. If you do not indicate
the number of units to be subscribed for on your subscription rights certificate, or if you indicate a number of units that does not
correspond with the aggregate subscription price payment you delivered, you will be deemed to have subscribed for the maximum number
of units that may be subscribed for, under both the basic subscription right and the over-subscription privilege, for the aggregate subscription
price you delivered. If the subscription agent does not apply your full subscription price payment to your purchase of units, then the
subscription agent will return the excess amount to you by mail, without interest or deduction, within 10 business days after the Expiration
Date. If you subscribe for fewer than all of the units represented by your subscription rights certificate, then the unexercised subscription

<B>Basic Subscription Right</B>. The shares of Series D Convertible Preferred Stock and warrants that are purchased pursuant to the valid
exercise of basic subscription rights to purchase units will be issued in book-entry, or uncertificated, form meaning that you will receive
a direct registration (DRS) account statement from our transfer agent reflecting ownership of these securities if you are a holder of
record of Common Stock, Series B Preferred, Series C Preferred, or of Participating Warrants. Based on 24,727,495 shares of common stock
outstanding as of August 31, 2022, 19,306 shares of common stock issuable upon conversion of 26 shares of Series B Preferred Stock, 33,753
shares of common stock issuable upon conversion of 50 shares of Series C Preferred Stock, and 1,11,729 shares of common stock issuable
upon exercise of Participating Warrants, we would grant subscription rights to acquire 25,896,283 units but will only accept subscriptions
for 10,000 units. Accordingly, sufficient units may not be available to honor your subscription in full. If exercises of basic subscription
rights exceed the number of units available in the Rights Offering, we will allocate the available units pro-rata among the record holders
exercising the basic subscription rights in proportion to the number of shares of Common Stock each of those record holders owned or
are deemed to hold on the record date, relative to the number of shares owned or deemed to be held on the record date by all record holders
exercising the basic subscription right. If this pro-rata allocation results in any record holders receiving a greater number of units
than the record holder subscribed for pursuant to the exercise of the basic subscription rights, then such record holder will be allocated
only that number of units for which the record holder subscribed, and the remaining units will be allocated among all other record holders
exercising their basic subscription rights on the same pro rata basis described above. The proration process will be repeated until all
units have been allocated. If for any reason the amount of units allocated to you is less than you have subscribed for, then the excess
funds held by the subscription agent on your behalf will be returned to you, without interest, as soon as practicable after the Rights
Offering has expired and all prorating calculations and reductions contemplated by the terms of the Rights Offering have been effected,
and we will have no further obligations to you. The subscription agent will arrange for the issuance of the Series D Convertible Preferred
Stock and warrants as soon as practicable after the expiration of the Rights Offering, payment for the units subscribed for has cleared,
and all prorating calculations and reductions contemplated by the terms of the Rights Offering have been effected. If you hold your shares
of Common Stock, Series B Preferred, Series C Preferred, or participating warrants in the name of a custodian bank, broker, dealer, or
other nominee, The Depository Trust Company (&ldquo;DTC&rdquo;) will credit your account with your nominee with the securities you purchased
in the Rights Offering.</FONT></P>

<B>Over-Subscription Privilege</B>. The shares of Series D Convertible Preferred Stock and warrants that are purchased pursuant to the

meaning that you will receive a DRS account statement from our transfer agent reflecting ownership of these securities if you are a holder
of record of Common Stock, Series B Preferred, Series C Preferred, or of Participating Warrants. If over-subscription privilege requests
for units exceed the remaining units available, the remaining units will be allocated pro-rata among holders who over-subscribe based
on the number of shares of Common Stock held as of the record date by all holders exercising the over-subscription privilege. If this
pro rata allocation results in any holder receiving a greater number of units than the holder subscribed for, then such holder will be
allocated only the number of units for which the holder oversubscribed, and the remaining units will be allocated among all holders exercising
the over-subscription privilege on the same pro rata basis described above. The proration process will be repeated until all units have
been allocated. The subscription agent will arrange for the issuance of the Series D Convertible Preferred Stock and warrants as soon
as practicable after the expiration of the Rights Offering, payment for the units subscribed for has cleared, and all prorating calculations
and reductions contemplated by the terms of the Rights Offering have been effected. If you hold your shares of Common Stock, Series B

<B>Special Provisions Relating to the Exercise of subscription rights through the Depository Trust Company</B>. In the case of subscription
rights that are held of record through DTC, exercises of the subscription rights may be effected by instructing DTC to transfer subscription
rights from the DTC account of such holder to the DTC account of the subscription agent, together with certification as to the aggregate
number of subscription rights exercised pursuant to the subscription right by each beneficial owner of subscription rights on whose behalf
such nominee is acting, and payment of the subscription price for each unit subscribed for. Banks, brokers and other nominee holders
of subscription rights who exercise the basic subscription right and the over-subscription privilege on behalf of beneficial owners of
subscription rights will be required to certify to the subscription agent and SINTX as to the aggregate number of subscription rights
that have been exercised, and the number of units that are being subscribed for pursuant to the over-subscription privilege, by each
beneficial owner of subscription rights (including such nominee itself) on whose behalf such nominee holder is acting. In the event such
certification is not delivered in respect of a subscription rights certificate, the subscription agent shall for all purposes (including
for purposes of any allocation in connection with the over-subscription privilege) be entitled to assume that such certificate is exercised
on behalf of a single beneficial owner.</FONT></P>

acquire 25,896,283 units but will only accept subscriptions for 10,000 units. Accordingly, sufficient units may not be available to honor
your subscription in full. If exercises of basic subscription rights exceed the number of units available in the Rights Offering, we
will allocate the available units pro-rata among the record holders exercising the basic subscription rights in proportion to the number
of shares of Common Stock each of those record holders owned or are deemed to hold on the record date, relative to the number of shares
owned or deemed to be held on the record date by all record holders exercising the basic subscription right. If this pro-rata allocation
results in any record holders receiving a greater number of units than the record holder subscribed for pursuant to the exercise of the
basic subscription rights, then such record holder will be allocated only that number of units for which the record holder subscribed,
and the remaining units will be allocated among all other record holders exercising their basic subscription rights on the same pro rata
basis described above. The proration process will be repeated until all units have been allocated. If for any reason the amount of units
allocated to you is less than you have subscribed for, then the excess funds held by the subscription agent on your behalf will be returned
to you, without interest, as soon as practicable after the Rights Offering has expired and all prorating calculations and reductions
contemplated by the terms of the Rights Offering have been effected, and we will have no further obligations to you.</FONT></P>

described in the Prospectus, each beneficial owner of shares of Common Stock, Series B Preferred Stock, Series C Preferred Stock, or
of Participating Warrants is entitled to one subscription right for every share of Common Stock owned or deemed owned by such beneficial
owner on the record date, evidenced by non-transferable subscription rights certificates registered in the record holder&rsquo;s name
or its nominee. Each subscription right entitles holder to purchase one unit at the subscription price, which we refer to as the basic
subscription right. Unless we otherwise agree in writing, a person or entity, together with related persons or entities, may not exercise
subscription rights (including over-subscription privileges) to purchase units that, when aggregated with their existing ownership, would
result in such person or entity, together with any related persons or entities, owning in excess of 19.99% of our issued and outstanding

shares of Series B Preferred Stock, 33,753 shares of common stock issuable upon conversion of 50 shares of Series C Preferred Stock,
and 1,115,729 shares of common stock issuable upon exercise of Participating Warrants, the Company would grant subscription rights to
acquire 25,896,283 units but will only accept subscriptions for 10,000 units. Accordingly, sufficient units may not be available to honor
your subscription in full. If exercises of basic subscription rights exceed the number of units available in the rights offering, we
will allocate the available units pro-rata among the record holders exercising the basic subscription rights in proportion to the number
of shares of Common Stock each of those record holders owned or are deemed to hold on the record date, relative to the number of shares
owned or deemed to be held on the record date by all record holders exercising the basic subscription right. If this pro-rata allocation
results in any record holders receiving a greater number of units than the record holder subscribed for pursuant to the exercise of the
basic subscription rights, then such record holder will be allocated only that number of units for which the record holder subscribed,
and the remaining units will be allocated among all other record holders exercising their basic subscription rights on the same pro rata
basis described above. The proration process will be repeated until all units have been allocated. If for any reason the amount of units
allocated to you is less than you have subscribed for, then the excess funds held by the subscription agent on your behalf will be returned
to you, without interest, as soon as practicable after the rights offering has expired and all prorating calculations and reductions
contemplated by the terms of the rights offering have been effected, and we will have no further obligations to you.</FONT></P>

on 24,727,495 shares of common stock outstanding as of August 31, 2022, 19,306 shares of common stock issuable upon conversion of 26
shares of Series B Preferred Stock, 33,753 shares of common stock issuable upon conversion of 50 shares of Series C Preferred Stock,
and 1,115,729 shares of common stock issuable upon exercise of Participating Warrants, the Company would grant subscription rights to
acquire 25,896,283 units but will only accept subscriptions for 10,000 units. Accordingly, sufficient units may not be available to honor
your subscription in full. If exercises of basic subscription rights exceed the number of units available in the Rights Offering, the
Company will allocate the available units pro-rata among the record holders exercising the basic subscription rights in proportion to
the number of shares of Common Stock each of those record holders owned or are deemed to hold on the record date, relative to the number
of shares owned or deemed to be held on the record date by all record holders exercising the basic subscription right. If this pro-rata
allocation results in any record holders receiving a greater number of units than the record holder subscribed for pursuant to the exercise
of the basic subscription rights, then such record holder will be allocated only that number of units for which the record holder subscribed,
and the remaining units will be allocated among all other record holders exercising their basic subscription rights on the same pro rata
basis described above. The proration process will be repeated until all units have been allocated. If for any reason the amount of units
allocated to you is less than you have subscribed for, then the excess funds held by the subscription agent on your behalf will be returned
to you, without interest, as soon as practicable after the Rights Offering has expired and all prorating calculations and reductions
contemplated by the terms of the Rights Offering have been effected, and the Company will have no further obligations to you.</FONT></P>

who fully exercise their basic subscription right will be entitled to subscribe for additional units that remain unsubscribed as a result
of any unexercised basic subscription right (the &ldquo;Over-Subscription Privilege&rdquo;). Subject to stock ownership limitations described
in the prospectus, if sufficient units are available, all Over-Subscription Privilege requests will be honored in full. If Over-Subscription
Privilege requests for units exceed the remaining units available, the remaining units will be allocated pro-rata among holders who over-subscribe
based on the number of shares of Common Stock owned or deemed to be owned or underlying the Series B Preferred Stock, Series C Preferred
Stock, or Participating Warrants held as of the record date by all holders exercising the Over-Subscription Privilege. If this pro rata
allocation results in any holder receiving a greater number of units than the holder subscribed for, then such holder will be allocated
only the number of units for which the holder oversubscribed, and the remaining units will be allocated among all holders exercising
the Over-Subscription Privilege on the same pro rata basis described above. The proration process will be repeated until all units have
