At the conclusion of the verbal negotiations, Big Buyer signs and sends this memo: "This is to confirm the purchase by Big Buyer of 1.5 million dollars of widgets, to be delivered at our Dayton facility no later than Dec 10, 2015, shipping cost to be paid by the seller." Under the UCC, is this contract enforceable?

1.) Clearly enforceable because enough specific terms are included

2.)Not enforceable because one key term required by the Code is lacking

3.) No because it is not a formal document, witnessed by two parties

4.) None of the above
