Discount proposed rate for a 10 yr lease over a 5 yr

[Ben S.]

I have a large warehouse space that a company is looking at.  They sent an RFP for rates for a 5, 7, and 10 year lease.  It is a well known international company and I would love the security of having a 10 year lease signed with them, but am not sure how much that is worth to me.  Is there another way to put the proposal together to make the 10 year option more appealing to them other than decreasing the rent$/sf?
