Rita has found an antique car she feels she just cannot live without, but she does not have enough money to pay for the car. Rita knows Rick, the owner of the car, pretty well, so Rita proposes a deal to him. Rita's elderly aunt Jolene has been ill for some time and is not expected to live much longer. Jolene has assured Rita for years that Rita will inherit a very large sum of money when Jolene dies. Rita offers to sign a promissory note to Rick for $500 over the asking price of the car, payable when Rita receives her inheritance. Rick agrees, because this gives him an extra $500, and Rita signs and dates the note. The note signed by Rita to Rick is:

a negotiable instrument, because Rita signed the note.

a negotiable instrument, because it is for a definite amount.

not a negotiable instrument, because the amount is not definitely stated.

not a negotiable instrument, because it is conditioned on Rita receiving an inheritance from her aunt in the future.
