The terms of the agreement are the terms of the offer.
Notice how UCC 2-207 operates in two stages. First, under 2-207(1), you decide whether an offer was accepted. Second, if you decide the offer was accepted, then under 2-207(2) you decide what the terms of the resulting agreement are.
Nothing you decide about what the terms are under 2-207(2) can change your decision that an offer was accepted under 2-207(1). It is a surprisingly common error to import 2-207(2) considerations into a 2-207(1) application.
