8. Shareholders’ Equity

Common Stock

Holders of Common Stock are entitled to one vote per share on all matters to be voted on by shareholders and do not have cumulative voting rights.  Subject to preferences of any Preferred Stock, the holders of Common Stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by the Board of Directors out of funds legally available for that purpose.  The Company does not expect to pay dividends in the foreseeable future.  In the event of liquidation, dissolution or winding up of the Company, holders of Common Stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of any Preferred Stock then outstanding.  The Common Stock has no preemptive or conversion rights or other subscription rights.  There are no redemption or sinking fund provisions applicable to the Common Stock.  All outstanding shares of Common Stock are fully paid and non-assessable.
