I would have grave concerns in signing this document! Preventing you from working within 100 miles for 2 years after leaving? Are they indicating that you would have to move town just to live and work in the event that you should leave as you could not reasonably commute that distance every day? I wouldn't say that any employeris within their rights to force those kind of demands. If they were to relocate you permanently anywhere, they should be consulting with all / any affected employees.
Are they implying they effectively own you?
If this is serious, I would be seeking legal advice before putting pen to paper. These clauses, if true, are laughable in my opinion.
