Well the terms are that you are licensing the software and if you breach the terms I would assume that the license is invalidated. However in reality they will never know although you know you are infringing their copyright. I generally hate non open source software licenses but this area of the terms doesn't seem overly unreasonable to me as they are offering a discount from the normal price for individuals but without extending it to the (usually) less price sensitive companies.
