I agree totally with what Nick (pinnies4me) has said here re the lease.  I see it all the time when i put expensive security systems into peoples leased premises.
They spend ALOT of money fitting out the shop/commercial premises and have a lease which would cause me to have no sleep at night. 

Many times I have told people to get a 5 year lease with a 5 year option if possible, without bodgy owner exit clauses, BEFORE spending $300 grand fitting the place out. AND even then, you will end up losing the entire $300 grand u have put into fixtures when the owner doesnt extend your lease past 5 yrs if you dont take a 5 year option.

Many times, I have told people to just walk away before they blow everything they have ever earnt and saved. BUT SOME PEOPLE REFUSE TO LISTEN. Its a shame this guy spent all that money, and 5 minutes after he finishs his dream building/business, he gets kicked to the kerb. He shld have got a better solicitor, and a better lease. Shame.
