I have a look at the contract to see what extras they want from my time not covered by normal work hours. Treat it like an options contract: if they want to option my future time, for example expecting me to do things (or not do things) after I leave their employment, they should pay for that up front. The only thing I'd point out is that you should be sure you're willing to walk away from the opportunity they're offering you, before you push too hard. You need to be okay with them saying no to your terms.
