Nan read the note that Tom had just given her. She was doing some home repair for Tom. The note represented the $10,000 that Nan and Tom agreed upon for all of the work. The note read as follows:

I, Tom Drum, hereby promise to pay to the order of Nan Hardy ten thousand dollars ($10,000). This sum is contingent upon my ability to receive a loan in the same amount from West Bank International. I give this negotiable instrument as the full payment for Nan Hardy's repairs to my home.

Is this note negotiable? Discuss why or why not.
