For the balance due on the purchase of a tractor, Henry Brown executed and delivered to Jane Jones his promissory note containing the following language:

January 1, 2016, I promise to pay to the order of Jane Jones the sum of \($7,000\) to be paid only out of my checking account at the XYZ National Bank of Pinckard, Illinois, in two installments of \($3,500\) each, payable on May 1, 2016, and on July 1, 2016, provided that if I fail to pay the first installment on the due date, the entire sum shall become immediately due.

Is the note negotiable? Explain.
