Exhibit
4.6


 


DESCRIPTION
OF THE REGISTRANT’S SECURITIES REGISTERED PURSUANT

TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934


 


The
following is a description of our common stock and preferred stock as set forth in our certificate of incorporation and bylaws,
each of which are incorporated by reference as an exhibit to the Annual Report on Form 10-K to which this Exhibit 4.6 is a part.
This summary does not purport to be complete and is qualified in its entirety by the full text of our aforementioned certificate
of incorporation and bylaws and by applicable law.


 


Our
authorized capital stock consists of 500,000,000 shares of common stock, par value $0.0001 per share and 10,000,000 shares of
Preferred Stock, par value $0.0001 per share.


 


The
additional shares of our authorized stock available for issuance might be issued at times and under circumstances so as to have
a dilutive effect on earnings per share and on the equity ownership of the holders of our common stock. The ability of our board
of directors to issue additional shares of stock could enhance the board’s ability to negotiate on behalf of the stockholders
in a takeover situation but could also be used by the board to make a change-in-control more difficult, thereby denying stockholders
the potential to sell their shares at a premium and entrenching current management. The following description is a summary of
the material provisions of our capital stock. You should refer to our amended and restated certificate of incorporation and by-laws,
both of which are on file with the SEC as exhibits to previous SEC filings, for additional information. The summary below is qualified
by provisions of applicable law.


 


Common
Stock


 


Voting.
The holders of our common stock are entitled to one vote for each share held of record on all matters on which the holders are
entitled to vote (or consent to).


 


Dividends.
The holders of our common stock are entitled to receive, ratably, dividends only if, when and as declared by our board of
directors out of funds legally available therefor and after provision is made for each class of capital stock having preference
over the common stock (including the common stock).


 


Liquidation
Rights. In the event of our liquidation, dissolution or winding-up, the holders of our common stock are entitled to share,
ratably, in all assets remaining available for distribution after payment of all liabilities and after provision is made for each
class of capital stock having preference over the common stock (including the common stock).


 


Conversion
Rights. The holders of our common stock have no conversion rights.


 


Preemptive
and Similar Rights. The holders of our common stock have no preemptive or similar rights.

our common stock are fully-paid and nonassessable.

Preferred
Stock


 


We
are authorized to issue up to 10,000,000 shares of preferred stock, par value $0.0001 per share, (of which 1,600,000 shares have
been designated as Series A Preferred Stock) with such designations, rights, and preferences as may be determined from time to
time by our board of directors. Accordingly, our board of directors is empowered, without stockholder approval, to issue preferred
stock with dividend, liquidation, conversion, voting, or other rights that could adversely affect the voting power or other rights
of the holders of our common stock. The issuance of preferred stock could have the effect of restricting dividends on our common
stock, diluting the voting power of our common stock, impairing the liquidation rights of our common stock, or delaying or preventing
a change in control of our company, all without further action by our stockholders.


 




    	 



    	 



    




 


Our
board of directors has the authority, within the limitations and restrictions prescribed by law and without stockholder approval,
to provide by resolution for the issuance of shares of preferred stock, and to fix the rights, preferences, privileges and restrictions
thereof, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preference and the number
of shares constituting any series of the designation of such series, by delivering an appropriate certificate of amendment to
our amended and restated certificate of incorporation to the Delaware Secretary of State pursuant to the Delaware General Corporation
Law (the “DGCL”). The issuance of preferred stock could have the effect of decreasing the market price of the common
stock, impeding or delaying a possible takeover and adversely affecting the voting and other rights of the holders of our common
stock.


 


If
we offer a specific series of preferred stock under this prospectus, we will describe the terms of the preferred stock in the
prospectus supplement for such offering and will file a copy of the certificate establishing the terms of the preferred stock
with the SEC. To the extent required, this description will include:

each case, as to distributions of assets upon our liquidation, dissolution or winding up whether voluntarily or involuntarily.


 


Dividends.
Holders of the Series B Preferred are entitled to receive dividends payable as follows: (i) a number of shares of common stock
equal to 10% of the shares of common stock underlying the Series B Preferred then held by such holder on the 12 month anniversary
of the COD Effective Date, (ii) a number of shares of common stock equal to 15% of the shares of common stock underlying the Series
B Preferred then held by such holder on the 24-month anniversary of the COD Effective Date and (iii) a number of shares of common
stock equal to 20% of the shares of common stock underlying the Series B Preferred then held by such holder on the 36-month anniversary
of the COD Effective Date. In the event a purchaser in this offering no longer holds Series B Preferred as of the 12-month anniversary,
the 24-month anniversary or the 36 month anniversary, such purchaser will not be entitled to receive any dividends on such anniversary
date.


 


Optional
Conversion. Each share of Series B Preferred is convertible into shares of our common stock at any time at the option of the
holder at a conversion price $0.50 per share (subject to adjustment for reverse splits, stock combinations and similar changes
as provided in the certificate of designation). Holders of Series B Preferred are prohibited from converting Series B Preferred
into shares of our common stock if, as a result of such conversion, the holder, together with its affiliates, would beneficially
own more than 4.99% (or upon the election by a holder prior to the issuance of any shares of Series B Preferred, 9.99%) of the
total number of shares of our common stock then issued and outstanding. Dividends will not accrue and will not be paid following
optional conversion.

price of $0.50 per share upon the earlier of (i) the first FDA approval of one of our product candidates, (ii) the 36-month anniversary
of the COD Effective Date or (iii) the consent to conversion by holders of at least 50.1% of the outstanding shares of Series
B Preferred. In the event the Series B Preferred automatically converts into common stock prior to the 36 month anniversary of
the COD Effective Date, the holder on the date of such conversion shall also be entitled to receive those dividends which would
have been payable after the conversion date, as if the shares of Series B Preferred had remained unconverted and outstanding through
the 36 month anniversary of the COD Effective Date. Such dividend amount shall be payable as set forth above in shares of common
stock upon such automatic conversion.


 


Liquidation
Preference. In the event of a liquidation, dissolution or winding-up of our company, whether voluntary or involuntary, the
proceeds and/or assets of our company remaining after giving effect to such transaction, and the payment of all of our debts and
liabilities will be distributed first to the holders of our Series A Preferred Stock and thereafter to the holders of Series B
Preferred and then to stockholders of common stock (including the holders of our Series A Preferred Stock and Series B Preferred
on an “as converted” basis) on a pro rata basis.

holders of Series B Preferred will have no voting rights. However, we may not, without the consent of holders of a majority of
the outstanding shares of Series B Preferred, alter or change adversely the powers, preferences or rights given to the Series
B Preferred, increase the number of authorized shares of Series B Preferred, or enter into any agreement with respect to the foregoing.

Anti-takeover
Effects of Delaware Law and of our Amended and Restated Certificate of Incorporation


 


The
following paragraphs summarize certain provisions of the DGCL and our amended and restated certificate of incorporation that may
have the effect of discouraging an acquisition of Matinas. The summary does not purport to be complete and is subject to and qualified
in its entirety by reference to the DGCL and our amended and restated certificate of incorporation and by-laws, copies of which
are on file with the SEC. Please refer to “Additional Information” below for directions on obtaining these documents.


 


Section
203 of the Delaware General Corporation Law


 


We
are subject to Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in any
business combination with any interested stockholder for a period of three years after the date that such stockholder became an
interested stockholder, with the following exceptions:


 


	●	before
    such date, the board of directors of the corporation approved either the business combination or the transaction that resulted
    in the stockholder becoming an interested stockholder;
	●	upon
    completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder
    owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes
    of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those
    shares owned (i) by persons who are directors and also officers and (ii) employee stock plans in which employee participants
    do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or
    exchange offer; or
	●	on
    or after such date, the business combination is approved by the board of directors and authorized at an annual or special
    meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting
    stock that is not owned by the interested stockholder.


 


In
general, Section 203 defines business combination to include the following:


 


	●	any
    merger or consolidation involving the corporation and the interested stockholder;
	●	any
    sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;
	●	subject
    to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation
    to the interested stockholder;
	●	any
    transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class
    or series of the corporation beneficially owned by the interested stockholder; or
	●	the
    receipt by the interested stockholder of the benefit of any loss, advances, guarantees, pledges or other financial benefits
    by or through the corporation.


 


In
general, Section 203 defines an “interested stockholder” as an entity or person who, together with the person’s
affiliates and associates, beneficially owns, or within three years prior to the time of determination of interested stockholder
status did own, 15% or more of the outstanding voting stock of the corporation.


 


Certificate
of Incorporation and Bylaws


 


Our
certificate of incorporation and bylaws contain provisions that could have the effect of discouraging potential acquisition proposals
or tender offers or delaying or preventing a change of control of our company. These provisions are as follows: 


 


	●	they
    provide that special meetings of stockholders may be called only by the board of directors, President or our Chairman of the
    board of directors, or at the request in writing by stockholders of record owning at least fifty (50%) percent of the issued
    and outstanding voting shares of common stock;
	●	they
    do not include a provision for cumulative voting in the election of directors. Under cumulative voting, a minority stockholder
    holding a sufficient number of shares may be able to ensure the election of one or more directors. The absence of cumulative
    voting may have the effect of limiting the ability of minority stockholders to effect changes in our board of directors; and
	●	they
    allow us to issue “blank check” preferred stock, the terms of which may be established and shares of which may
    be issued without stockholder approval.


 


Potential
Effects of Authorized but Unissued Stock


 


We
have shares of common stock and preferred stock available for future issuance without stockholder approval. We may utilize these
additional shares for a variety of corporate purposes, including future public offerings to raise additional capital, to facilitate
corporate acquisitions or payment as a dividend on the capital stock.


 


The
existence of unissued and unreserved common stock and preferred stock may enable our board of directors to issue shares to persons
friendly to current management or to issue preferred stock with terms that could render more difficult or discourage a third-party
attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise, thereby protecting the continuity
of our management. In addition, the board of directors has the discretion to determine designations, rights, preferences, privileges
and restrictions, including 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 DGCL and subject to any limitations set forth
in our amended and restated certificate of incorporation. The purpose of authorizing the board of directors to issue preferred
stock and to determine the rights and preferences 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 of our outstanding voting stock.
