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

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

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

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

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

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

current corporate strategy includes the possibility of entering into additional collaborative arrangements with third parties
to expand and improve the commercialization of all our products, including our silicon nitride ceramics. Consistent with this
strategy, we continue to seek to identify opportunities and, if possible, secure a transaction or transactions relating to our
business, including, but not limited to, partnering or other collaborative agreements, a sale of the Company or of assets and/or
other strategic arrangements. There can be no assurance that the exploration of strategic alternatives will result in any agreements

of March 27, 2018, there were warrants outstanding to purchase a total of 1,563,430 shares of our Common Stock, all of which expire
between August 2018 and March 2023. Each of these warrants entitles the holder to purchase one share of Common Stock at prices
ranging from $2.00 to $9,279.00 per common share, with a weighted average exercise price of $9.04 per share. Certain of these
warrants have a net exercise provision under which its holder may, in lieu of payment of the exercise price in cash, surrender
the warrant and receive a net number of shares based on the fair market value of our Common Stock at the time of exercise of the
warrant after deduction of the aggregate exercise price. Each of these warrants also contains provisions for the adjustment of
the exercise price and the aggregate number of shares issuable upon the exercise of the warrant in the event of dividends, share
splits, reorganizations, reclassifications and consolidations. 70,426 of these warrants contain a provision requiring a reduction
to the exercise price in the event we issue Common Stock, or securities convertible into or exercisable for Common Stock, at a
price per share lower than the warrant exercise price, which provision will be triggered by this offering.</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">As
compensation paid in connection with the consummation of two private placements in 2014, the Company issued two warrants to Westlake
Securities LLC (the &ldquo;2014 Westlake Warrants&rdquo;). The first 2014 Westlake Warrant was issued September 17, 2014, and
the second 2014 Westlake Warrant was issued November 12, 2014. The 2014 Westlake Warrants are each exercisable for five years
after the date of issuance. As a result of the Company&rsquo;s reverse stock splits the first 2014 Westlake Warrant is exercisable
for 278 shares of Common Stock as of the date of this prospectus at an exercise price of $154.80 per share, and the second 2014
Westlake Warrant is exercisable for 833 shares of Common Stock as of the date of this prospectus at an exercise price of $225.00
per share. The 2014 Westlake Warrants have a net exercise provision under which the holder may, in lieu of payment of the exercise
price in cash, surrender the warrant and receive a net number of shares of Common Stock 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 the 2014 Westlake
Warrants contains provisions for the adjustment of the exercise price and the aggregate number of shares of Common Stock issuable
upon the exercise of the warrant in the event of dividends, share splits, reorganizations, reclassifications and consolidations.
These 2014 Westlake Warrants are attached as Exhibits 4.15 and 4.16 to the registration statement of which this prospectus is
a part and are incorporated herein by reference.</FONT></P>

August 30, 2013 and September 20, 2013, the Company issued and sold a total of 94.8 units, with each unit consisting of 50,000
shares of Series F convertible preferred stock and a warrant to acquire 25,000 shares of Common Stock at an exercise price of
$1.00 per share, to 45 accredited investors at $100,000 per unit for an aggregate purchase price of $9,480,000. The purchase of
these units resulted in the issuance of warrants to purchase 2,370,000 shares of Common Stock. These warrants are exercisable
until five years from the date of issuance. As a result of the reverse stock splits which occurred in February 2013, January 2015
and November 2017, since these warrants were issued and certain subsequent issuances of securities below the original exercise
price of this warrant, these warrants are exercisable for 512 shares of Common Stock as of the date of this prospectus, at an
exercise price of $2.00 per share. 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. These warrants also have a net exercise provision under which the holder may, in lieu of payment of the exercise
price in cash, surrender the warrant and receive a net number of shares of Common Stock 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 of Common Stock issuable upon

is no authority directly addressing the treatment, for U.S. federal income tax purposes, of securities with terms substantially

purchase price for each Unit must be allocated between the underlying Series B Preferred Stock and Warrants in proportion to their

foregoing treatment of the Units and a holder&rsquo;s purchase price allocation are not binding on the IRS or the courts. Because

certain limited circumstances, a U.S. holder may be permitted to undertake a cashless exercise of Warrants into shares of our
Common Stock. The U.S. federal income tax treatment of a cashless exercise of Warrants into shares of Common Stock is unclear,
and the tax consequences of a cashless exercise could differ from the consequences upon the exercise of a Warrant described in
the preceding paragraph. A cashless exercise may be tax-free, either because the exercise is a non-recognition event or because
the exercise is treated as a recapitalization for U.S. federal income tax purposes. It is also possible that a cashless exercise
could be treated as a taxable exchange in which a U.S. holder would recognize gain or loss. If the cashless exercise is treated
as a taxable exchange, the exchanging holder would recognize capital gain or loss in an amount equal to the difference between
the fair market value of the Common Stock received and the U.S. holder&rsquo;s tax basis in the Warrants exercised.</FONT></P>

respect to a redemption of our Series B Preferred Stock that is treated as a distribution with respect to our shares, which is

would not permit the transfer of basis in the redeemed shares of the Series B Preferred Stock to the remaining shares held (directly
or indirectly) by the redeemed U.S. holder. Instead, the unrecovered basis in our Series B Preferred Stock would be treated as
a deferred loss to be recognized when certain conditions are satisfied. These proposed Treasury regulations would be effective
for transactions that occur after the date the regulations are published as final Treasury regulations. There can, however, be

U.S. federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United

871(m) of the Code requires withholding (up to 30%, depending on whether a treaty applies) on certain financial instruments to

be treated as dividend equivalents (&ldquo;dividend equivalents&rdquo;) that are subject to U.S. withholding tax at a rate of
30% (or lower treaty rate). Under these U.S. Treasury Regulations, withholding may be required even in the absence of any actual
dividend related payment or adjustment made pursuant to the terms of the instrument. The regulations as originally adopted were
to be effective for all covered contracts and instruments issued on or after January 1, 2017, but the IRS has extended such date
to apply to all covered contracts and instruments issued on or after January 1, 2019. If withholding is required, we (or the applicable

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

Each Notice of Conversion shall specify the number of shares of Preferred Stock to be converted, the number of shares of Preferred

the Corporation unless all of the shares of Preferred Stock represented thereby are so converted, in which case such Holder shall

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

of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination,

obligation of the Corporation to such Holder in connection with the issuance of such Conversion Shares; provided, however, that
such delivery shall not operate as a waiver by the Corporation of any such action that the Corporation may have against such Holder.
In the event a Holder shall elect to convert any or all of the Stated Value of its Preferred Stock, the Corporation may not refuse
conversion based on any claim that such Holder or anyone associated or affiliated with such Holder has been engaged in any violation
of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and/or enjoining
conversion of all or part of the Preferred Stock of such Holder shall have been sought and obtained, and the Corporation posts
a surety bond for the benefit of such Holder in the amount of 150% of the Stated Value of Preferred Stock which is subject to
the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the underlying dispute and
the proceeds of which shall be payable to such Holder to the extent it obtains judgment. In the absence of such injunction, the
Corporation shall issue Conversion Shares and, if applicable, cash, upon a properly noticed conversion. If the Corporation fails
to deliver to a Holder such Conversion Shares pursuant to Section 5(c)(i) by the Share Delivery Date applicable to such conversion,
the Corporation shall pay to such Holder, in cash, as liquidated damages and not as a penalty, for each $5,000 of Stated Value

to $200 per Trading Day on the sixth Trading Day after such damages begin to accrue) for each Trading Day after the Share Delivery

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

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

Stock equal to the number of shares of Preferred Stock submitted for conversion (in which case, such conversion shall be deemed
rescinded) or deliver to such Holder the number of shares of Common Stock that would have been issued if the Corporation had timely
complied with its delivery requirements under Section 5(c)(i). For example, if a Holder purchases shares of Common Stock having
a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Preferred Stock with
respect to which the actual sale price of the Conversion Shares (including any brokerage commissions) giving rise to such purchase
obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Corporation shall be required to
pay such Holder $1,000. The Holder shall provide the Corporation written notice indicating the amounts payable to such Holder
in respect of the Buy-In and, upon request of the Corporation, evidence of the amount of such loss. Nothing herein shall limit
a Holder&rsquo;s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation,

the number of shares of Common Stock beneficially owned by such Holder and its Affiliates and Attribution Parties shall include
the number of shares of Common Stock issuable upon conversion of the Preferred Stock with respect to which such determination
is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion of the remaining,
unconverted Stated Value of Preferred Stock beneficially owned by such Holder or any of its Affiliates or Attribution Parties
and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Corporation subject to
a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, the Preferred
Stock or the Warrants) beneficially owned by such Holder or any of its Affiliates or Attribution Parties. Except as set forth
in the preceding sentence, for purposes of this Section 5(d), beneficial ownership shall be calculated in accordance with Section
13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation contained in
this Section 5(d) applies, the determination of whether the Preferred Stock is convertible (in relation to other securities owned
by such Holder together with any Affiliates and Attribution Parties) and of how many shares of Preferred Stock are convertible
shall be in the sole discretion of such Holder, and the submission of a Notice of Conversion shall be deemed to be such Holder&rsquo;s
determination of whether the shares of Preferred Stock may be converted (in relation to other securities owned by such Holder
together with any Affiliates and Attribution Parties) and how many shares of the Preferred Stock are convertible, in each case
subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, each Holder will be deemed to represent
to the Corporation each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions
set forth in this paragraph and the Corporation shall have no obligation to verify or confirm the accuracy of such determination.
In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d)
of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 5(d), in determining the
number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as stated
in the most recent of the following: (i) the Corporation&rsquo;s most recent periodic or annual report filed with the Commission,
as the case may be, (ii) a more recent public announcement by the Corporation or (iii) a more recent written notice by the Corporation
or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder,
the Corporation shall within two Trading Days confirm orally and in writing to such Holder the number of shares of Common Stock
then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the
conversion or exercise of securities of the Corporation, including the Preferred Stock, by such Holder or its Affiliates or Attribution
Parties since the date as of which such number of outstanding shares of Common Stock was reported. The &ldquo;<U>Beneficial Ownership
Limitation</U>&rdquo; shall be 4.99% (or upon the election by a Holder prior to the issuance of any shares of Preferred Stock)
of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock
issuable upon conversion of Preferred Stock held by the applicable Holder. A Holder, upon notice to the Corporation, may increase
or decrease the Beneficial Ownership Limitation provisions of this Section 5(d) applicable to its Preferred Stock provided that
the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock upon conversion of this Preferred Stock held by the Holder and the
provisions of this Section 5(d) shall continue to apply. Any such increase in the Beneficial Ownership Limitation will not be
effective until the 61st day after such notice is delivered to the Corporation and shall only apply to such Holder and no other
Holder. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with
the terms of this Section 5(d) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the
intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly
give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of Preferred Stock.</FONT></P>

<U>Calculation of Consideration Received</U>. If any Option and/or Common Stock Equivalent and/or Adjustment Right is issued in

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

on the conversion of this Preferred Stock), the number of shares of Common Stock of the successor or acquiring corporation or
of the Corporation, 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 Preferred
Stock is convertible immediately prior to such Fundamental Transaction (without regard to any limitation in Section 5(d) on the
conversion of this Preferred Stock). For purposes of any such conversion, the determination of the Conversion 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 Corporation shall apportion the Conversion 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 conversion of this Preferred
Stock following such 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, the Underwriting Agreement and the
Warrants in accordance with the provisions of this Section 6(d) 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 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, the Underwriting Agreement
and the Warrants 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,
the Underwriting Agreement and the Warrants with the same effect as if such Successor Entity had been named as the Corporation
herein.</FONT></P>

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

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

<U>Holder&rsquo;s Right of Alternative Exercise Price</U>. In addition to and not in limitation of the other provisions of this

<U>Subsequent Rights Offerings</U>. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company
grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata
to the record holders of any class of shares of Common Stock (the &ldquo;<U>Purchase Rights</U>&rdquo;), then the Holder will
be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could
have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without
regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before
the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the

Rights (provided, however, to the extent that the Holder&rsquo;s right to participate in any such Purchase Right would result
in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase
Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent)

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