Restated Certificate of Incorporation, a copy of which is filed herewith as Exhibit 3.1 (the &#147;<I>Charter</I>&#148;), holders of Common Stock are entitled to receive ratably dividends out of funds legally available, if and when declared from
time to time by our Board of Directors. The Company has never paid any cash dividends on its Common Stock and the Company&#146;s Board of Directors does not anticipate that it will pay cash dividends in the foreseeable future. The future payment of
dividends, if any, on the Company&#146;s Common Stock is within the discretion of the Board of Directors and will depend upon earnings, capital requirements, financial condition and other relevant factors. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Holders of Common Stock are entitled to one vote for each share held on each matter to be voted on by stockholders. There is no cumulative
voting in the election of directors. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In the event of liquidation, dissolution or winding up of the affairs of the Company, holders of

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The holders of Common Stock have no preemptive or conversion rights and are not subject to further calls or assessments. There are no
redemption or sinking fund provisions applicable to the Common Stock. The rights of the holders of the Common Stock are subject to any rights that may be fixed for holders of preferred stock, if any. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The rights of the holders of Common Stock are delineated, in part, in our Amended and Restated Bylaws, a copy of which are filed herewith as
Exhibit 3.2 (the &#147;<I>Bylaws</I>&#148;). Pursuant to our Charter, the Board of Directors has the right to adopt, amend or repeal bylaws without a vote of the stockholders. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Stockholders wishing to bring forward proposals or director nominees for consideration at any meeting of stockholders must comply with the
notice requirements set forth in the Bylaws. Pursuant to the Bylaws, special meetings of stockholders may only be called by the Board of Directors, and only those matters set forth in the related notice of special meeting may be considered and acted
upon at such a meeting. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Preferred Stock </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Under the Charter, our Board of Directors, without further action by our stockholders, currently has the authority to issue up to 5,000,000
shares of Preferred Stock and to fix the rights (including voting rights), preferences and privileges of these &#147;blank check&#148; preferred shares. The Preferred Stock may have rights, preferences and privileges, including dividend, liquidation
and other economic rights, that are senior to the Common Stock. As a result, the designation of a series of Preferred Stock with preferential rights could negatively affect the rights (and value) of the Common Stock, and such diminution in rights
could be effected without a vote of the holders of the Common Stock. Furthermore, the issuance of Preferred Stock could make it more difficult for a third party to acquire a majority of our outstanding Common Stock or control of the Company. </P>
