(the “common stock”).

Report on Form 10-K of which this Exhibit 4.14 is a part. We encourage you to read the Certificate of Incorporation and the Bylaws,
as well as the applicable provisions of the Delaware General Corporation Law (the “DGCL”), for additional information.


 


Authorized
Capital Stock


 


Our
authorized capital stock consists of 100,000,000 shares of common stock and 20,000,000 shares of preferred stock, par value $0.0001
per share (the “Preferred Stock”). As of December 31, 2019, 30,682,520 shares of our common stock were issued and
outstanding, all of which are fully paid and nonassessable, and no shares of our Preferred Stock were issued and outstanding.


 


Common
Stock


 


Voting
Rights


 


Holders
of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not
have cumulative voting rights. An election of directors by our stockholders will be determined by a plurality of the votes cast
by the stockholders entitled to vote on the election.


 


Dividend
Rights


 


Holders
of common stock are entitled to receive proportionately any dividends that may be declared by our Board of Directors, subject
to any preferential dividend rights of any series of preferred stock that we may designate and issue.


 


Liquidation
Rights


 


In
the event of our liquidation or dissolution, the holders of common stock are entitled to receive proportionately our net assets
available for distribution to stockholders after the payment of all debts and other liabilities and subject to the preferential
rights of any outstanding preferred stock.

Absence
of Other Rights


 


Holders
of our common stock have no preemptive, subscription, redemption, or conversion rights. The rights, preferences, and privileges
of holders of common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of
preferred stock that we may designate and issue.


 


Preferred
Stock


 


Under
our Certificate of Incorporation, our Board of Directors has the authority, without further action by stockholders, to designate
one or more series of preferred stock and to fix the voting powers, designations, preferences, limitations, restrictions, and
relative rights granted to or imposed upon the preferred stock, including dividend rights, conversion rights, voting rights, rights
and terms of redemption, liquidation preference, and sinking fund terms, any or all of which may be preferential to or greater
than the rights of the common stock.


 


The
authority possessed by our Board of Directors to issue preferred stock could potentially be used to discourage attempts by third
parties to obtain control of our company through a merger, tender offer, proxy contest, or otherwise by making such attempts more
difficult or more costly. Our Board of Directors may issue preferred stock with voting rights, conversion rights, and other rights
that, if exercised, could adversely affect the voting power of the holders of common stock.


 


Anti-Takeover
Effects of Our Certificate of Incorporation and Bylaws


 


Certain
provisions of our Certificate of Incorporation and Bylaws contain provisions that could have the effect of delaying or discouraging
another party from acquiring control of us. These provisions, which are summarized below, are expected to discourage certain types
of coercive takeover practices and inadequate takeover bids.


 


Our
Certificate of Incorporation and Bylaws include provisions that:


 


		●	authorize
                                         our Board of Directors to issue, without further action by the stockholders, up to 20,000,000
                                         shares of preferred stock in one or more series designated by the Board of Directors;
	 	 	 
		●	specify
                                         that meetings of our stockholders can be called only by our Board of Directors, or any
                                         officer instructed by the director to call the meeting;
	 	 	 
		●	provide
                                         that vacancies on our Board of Directors may be filled only by the vote of a majority
                                         of the remaining directors even though less than a quorum.

Delaware
Anti-Takeover Statute


 


We
are subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. In general, Section 203 prohibits
a publicly-held Delaware corporation such as Lixte from engaging in a “business combination” with an “interested
stockholder” for a period of three years following the date the person became an interested stockholder unless:


 


		●	prior
                                         to the date of the transaction, the board of directors of the corporation approved either
                                         the business combination or the transaction which 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 commenced, excluding for purposes
                                         of determining the voting stock outstanding, but not for determining the outstanding
                                         voting stock owned by the interested stockholder, (1) shares owned by persons who
                                         are directors and also officers of the corporation and (2) shares owned by 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
	 	 	 
		●	at
                                         or subsequent to the date of the transaction, the business combination is approved by
                                         the board of directors of the corporation and authorized at an annual or special meeting
                                         of stockholders, and not by written consent, by the affirmative vote of at least 66-2/3%
                                         of the outstanding voting stock which is not owned by the interested stockholder.



 


In
this context, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a
financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates
and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of
a corporation’s outstanding voting stock. We expect the existence of this provision to have an anti-takeover effect with
respect to transactions our Board of Directors does not approve in advance. We also anticipate that Section 203 may discourage
business combinations or other attempts that might result in a premium over the market price for the shares of common stock held
by our stockholders.
