Common Stock
Voting rights. The common stock is entitled to one vote per share on any matter that is submitted to a vote of our stockholders. Our Certificate of Incorporation does not provide for cumulative voting for the election of directors. Our Certificate of Incorporation establishes a classified board of directors that is divided into three classes with staggered three-year terms. Only the directors in one class will be subject to election by a plurality of the votes cast at each annual meeting of our stockholders, with the directors in the other classes continuing for the remainder of their respective three-year terms. The affirmative vote of holders of at least 662∕3% of the voting power of all of the then outstanding shares of capital stock, voting as a single class, will be required to amend certain provisions of our Certificate of Incorporation, including provisions relating to amending our Bylaws, the classified structure of our board of directors, the size of our board of directors, removal of directors, director liability, vacancies on our board of directors, special meetings, stockholder notices, actions by written consent, competition and corporate opportunities, business combinations with interested stockholders and exclusive jurisdiction. Generally, all matters to be voted on by stockholders must be approved by a majority of votes cast affirmatively or negatively on a matter by stockholders (or, in the case of election of directors, by a plurality), voting together as a single class. Except as otherwise provided by law, amendments to the Certificate of Incorporation must be approved by a majority or, in some cases, a super-majority of the combined voting power of all shares entitled to vote, voting together as a single class.
Dividend rights. Subject to the rights and preferences of any holders of any outstanding series of preferred stock that we may designate and issue in the future, the holders of our common stock are entitled to receive proportionately any dividends as may be declared by our board of directors.
Liquidation rights. On our liquidation, dissolution, or winding-up, the holders of common stock will be 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 prior rights of any outstanding preferred stock.
No Preemptive or Similar Rights. The holders of our shares of common stock are not entitled to preemptive rights, and are not subject to conversion, redemption or sinking fund provisions.
Preferred Stock
Under our Certificate of Incorporation, our board of directors may, without further action by our stockholders, fix the rights, preferences, privileges and restrictions of up to an aggregate of 50,000,000 shares of preferred stock in one or more series and authorize their issuance. These rights, preferences and
