The "unit" sales included warrants worth 3/4 shares so the 85 million shares also include 61 million convertible at $.25. These private investors have significant incentive to sell fast and pocket nice profit with very little risk. The "unit" sales now represents 146 million shares which is close to tapping the amount available. They are also paying management in shares adding to the count.
They also need the shares to payoff Fife's vulture fund payments, keep paying Samsung and eventually the rest of the Amarex debt that might be due. Lots of debt overhang and they can't do a S-3 secondary (while under SEC investigation) so have to keep doing private placements a very attractive discounts like this one (almost 40% discount including Paulson's 13% commission).
