Their purchases are a show of good faith.
Martin 20K
Pascoe 35K
Rusty Ray 5K
However, I too would have liked to have seen more shares purchased. These appear to be Martin's first shares! Pascoe, I am sure, will get stock as payment or bonus.
For the money the Greek (obviously no disrespect) on the board gets as CEO of Regulus, it baffles me why he is on a program to routinely sell in small chunks the 100K shares he got for agreeing to become a board member.
I imagine Damaj is a pretty unhappy camper. Just before "his" dilution in Feb 2012 he had $8M worth of stock. Now he has just half that.
