Number of common stock issued description                 The number of common stock shares to be issued in a qualified event shall be equal to the amount due on the conversion date divided by the lesser of a capped conversion price (the “Capped Conversion Price”) and the qualified event price (the “Qualified Event Price”). The Capped Conversion Price is calculated as $50.0 million divided by the number of shares of common stock outstanding at such time on a fully diluted basis. The Qualified Event Price is the price per share determined by the qualified event. A qualified financing is a sale or series of sales of preferred stock where (i) at least 50 percent of counterparties are not existing shareholders, (ii) net proceeds to Syndeio are at least $35.0 million, and (iii) the stated or implied equity valuation of Syndeio is at least $80.0 million.
