RE: RE: warrants (expiration date)A key bit of data missing from your chart is the fact that the "B" and "C" warrants convert at 10 warrants per share of stock.
The "A" warrant converts at 1 to 1.
I think the "A"s are far superior to the others, and actually prefer them to the shares at this point.
Here is a pretty good chart for warrants:
