Liscense question

I read the license agreement and I am confused. If I buy a license to TGEA, say indie considering I make nothing right now, does it or does it not allow me and others in my "company" to use it. For instance if I am in a club with about 5 programmers does that mean we would have to buy 5 licenses to the engine in order to use it? I understand not distributing it, but they can't even use it?
