The Series A Convertible Preferred Stock will be entitled to dividends on an as-if-converted basis in the same form as any dividends actually paid on shares of the Company’s common stock or other securities. The initial conversion price of $2.00 is subject to appropriate adjustment in the event of a stock split, stock dividend, combination, reclassification or other recapitalization affecting the Company’s common stock. In addition, for a period ending on the earlier of one year from effective date of a resale registration Statement or the date on which there are no shares of Series A Convertible Preferred Stock outstanding, the conversion price is also subject to full ratchet anti-dilution protection in the event the Company issues securities at an effective price less than the initial conversion price, subject to certain exceptions.
