Golf Inc. manufactures golf balls. Jack orders 1,000 balls from Golf and promises to pay $4,000 two weeks after delivery. Golf Inc. delivers the balls and assigns its contract rights to First Bank for $3,500. Golf Inc. then declares bankruptcy. Assuming that Jack gives Golf Inc. a nonnegotiable note for $3,500 and Golf sells the note to the bank shortly after delivering the balls. May the bank collect the $3,500? Would the result be different if the note were negotiable? Explain.
