When a company is in significant financial distress and its options have been rendered worthless, there is a high incentive for very senior management to leave the company. That is basically the WORST thing that can happen to a company that is already in trouble.
Structuring packages for senior executives to stay through troubled times is very, very standard. I won't comment on how rich those packages were. Maybe there were too much, I dunno. I'm not going to analyze each one and compare to industry averages. The point remains, however, that companies in trouble need to incentivize management to stay.
