They are set up on conditions, my guess is share price. The 10b5-1 plan was set up for personal reasons by Kim, and its existence is not necessarily a bad sign or a good sign. The plan existing and (if) they truly didnt execute, that shows Kim's high future expectations of KBLB.
Whether he is taking his salary and using it for KBLB........no idea, it would be a really good sign if this were the case as well, but not necessary.
