[1] Each share of common stock is entitled to one vote per share on all matters submitted to a vote of the shareholders.
[2] Each share of class A common stock is entitled to 10 votes per share on all matters submitted to a vote of the shareholders. Each holder of class A common stock is entitled to convert, at any time, any and all of such shares into the same number of shares of common stock. Each share of class A common stock is converted automatically into common stock in the event that the beneficial or record ownership of such shares of class A common stock is transferred to any person, except to certain family members or affiliated persons deemed “permitted transferees” pursuant to the Company’s Restated Certificate of Incorporation as amended. The class A common stock is not publicly traded and consequently, there is currently no established public trading market for these shares.
