So far you've gotten some great advice in the other comments: Don't agree to sleazy terms, get a lawyer involved, etc. But in addition to all that, here is another point I didn't see mentioned so far. After working for yourself for 5 years, (or perhaps more) do you really want to take a corporate job? Speaking for myself, after working for myself for a lengthy period of time, I'm quite sure I don't want to have a "9-5" ever again. I've turned down a number of job offers over the years, and I have no regrets. If the deal is all cash, paid in full at closing, then it doesn't matter (too much) if you get fired on day 2. You can go right back out there and start another company.
