I think you'll shout about 'insider dealing' in any case anyway. Leaving this unsettled doesn't seem to me as big a deal as it is to you. There may well be a difference in whether the term should be 2 years or 4 years and believe it or not the BoD have other things going on and maybe settling that point has just not been a high priority to them as it is to you conspiracy theorists.
I'm not a lawyer nor a corporate governance specialist but I don't buy that it's as simple as she can cut herself a $4M check any time she wants to. That sounds like nonsense because it would be shocking lack of fiscal control if that were the case where she would be writing a check in that amount to herself. Just the sort of thing that would be yet another cause for you to squawk.
