Delaware
Anti-Takeover Law


 


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, our 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 our 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 before 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/or bylaws provide that:


 


	 	●	our
    bylaws may be amended or repealed by our board of directors or our stockholders;
	 	●	our
    board of directors will be authorized to issue, without stockholder approval, preferred stock, the rights of which will be
    determined at the discretion of our board of directors and that, if issued, could operate as a “poison pill” to
    dilute the stock ownership of a potential hostile acquirer to prevent an acquisition that our board of directors does not
    approve;
	 	●	our
    stockholders do not have cumulative voting rights, and therefore our stockholders holding a majority of the shares of common
    stock outstanding will be able to elect all of our directors; and
	 	●	our
    stockholders must comply with advance notice provisions to bring business before or nominate directors for election at a stockholder
    meeting.


 


Stockholder
Rights Plan


 


On
November 19, 2002, our board of directors declared a dividend distribution of one Right (a “Right”) for each outstanding
share of common stock to stockholders of record at the close of business on November 29, 2002. On November 14, 2017, at the direction
of our board of directors, we amended and restated our Rights Agreement with American Stock Transfer & Trust Company, LLC,
as amended and restated, or the Rights Agreement. Each Right entitles the registered holder to purchase from us a unit consisting
of one one-hundredth of a share, or a Unit, of Series A Junior Participating Preferred Stock, par value $0.01 per share, or the
Series A Preferred Stock, at a Purchase Price of $21.00 per Unit, subject to adjustment. The description and terms of the Rights
are set forth in the Rights Agreement. The foregoing description of the Rights and the Rights Agreement are qualified in their
entire by reference to the disclosure in our Registration Statement on Form 8-A12B (No. 0-27072) and the Rights Agreement filed
therewith, filed with the SEC on November 14, 2017, with such filing and exhibit being herein incorporated by reference.


 


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, our 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 Delaware General Corporation Law and subject
to any limitations set forth in our certificate of incorporation. The purpose of authorizing our 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.
