Also remember you can always treat agreements as negotiations. Tell them you don't agree to that part and cross it out and see what their response is.

(For the record that's always worked for me in employment contracts where the first offer has been some ridiculously broad non-compete. I've always has some variation of "Oh yeah - that's just HRs standard boilerplate, obviously we don't mean to have that apply to _you_ - just cross it out and I'll initial and sign it without that clause...")
