Chazzle is correct. The directors and key execs are required to be listed on the form. It isn't an indication that they bought. if they bought, it would be disclosed on a different form. Also correct that 21 different people participated to create the $1.89 million that was disclosed as gross proceeds.
Riz - you could call Paulson and ask to participate. This offering was disclosed recently. I think they are selling 1 share with .75 warrants as a "unit."
Each "unit" has a price. It is probably in the last 10q, but I haven't looked it up. Likely around 25 cents. Shares and warrants will not be registered.
