Actually, most lease agreements in major shopping centres have these clauses..
I know two main ones that have used the clause to get tenants out..
the first clause is they can move your shop anywhere in the complex.. so one day you are near the main entrance.. next you knwo you have to relocate to the shop near the bins
the second is.. your lease might be for 5 years and you can not get out.. by they only have to give you 6 weeks..
look at the melbourne eye.. no lease had a break out if the eye was removed.. so they all pay huge rent.. and no attraction..
