The "Seller" receives preferred shares based upon a pre-arranged dollar amount, no matter how many commons it would take... Yes, shares that could be "converted to commons" at any time they wish & usually convert at between 85-95% of the average 5 days (although those "C" shares convert at 21.25% - talk about a deal for family!)
Not only that... but look at Swartz's deal.... Preferred D Shares, along with $50k worth of commons per year (figuring current pps that would be at least 125 million common shares! EVERY YEAR) on top of a $125k gauranteed salary, even if he was fired!
Yes, the preferred shares may hold things off for a little while on the big chunk of it, but it's worse for the common shareholder even more with every deal TS does!
