I respectfully disagree. If Mark’s purchase was out of greed he could easily pick up a phone and pen make his purchase known to SEC and have 30% more shares at market prices.
To exercise these warrants he is choosing to put money in the companies coffers before his warrants expire.

This move is clearly showing confidence to shareholders at a substantial extra cost to him, as walterc suggests

The only downside is a bit of share dilution.
