From what I have read in other filings, there seemed to be a 60-day window from Jan to March that these were filled. That's just the impression I get from the language used in a couple of their filings in February, nothing really concrete. I don't know if that information is spelled out anywhere specifically though, I have searched and couldn't find it. There was/were at least 2 entities holding convertible warrants, one of which is Millenium Capital, and another is Midmark.
