Not to add to the speculation, but if I was Wittenberg and I thought the stock price was going higher from here, I would exercise my stock options in a heartbeat. The stock price can't go down much farther (a few cents), but it could certainly shoot way up (several dollars) if good news were forthcoming.
Now that I think about it, if Wittenberg was convinced that the company was going bankrupt, why would he even exercise his stock options and pay the $2000 for the stock plus incur the added tax liability. Doesn't make much sense to me.
