But it's the first time I'm asked to sign one of these things and some of the things I'd be agreeing to doesn't even sound like it's in english. I don't want to inadvertently sign over any side project I was working on in that time or IP for the industry I was working in or even future IP as some of it seems to be worded without time constraints. But take all that with a grain of salt, no legal background.
The sale of the business is predicated on all former employees signing the deed.
