As per the Prodigy Web site, there are 17.7 Million Purchase Warrants as of April 14, 2011. Also as of that date, Prodigy had $10 Million in working capital.
I don't believe there is any hold period on the warrants once they are converted to shares. I already exercised my warrants and, although I am keeping them, there is no reason why I could not sell them if I choose.
