QUESTION 3. An instrument reads as follows

$25,000 Mt. Pleasant MI February 14, 2008

I promise to pay to the order of Paste Jewelry Corp., $25,000 within 10 days after the sale of my three carat diamond ring. I pledge the sale proceeds to secure my obligation hereunder.

s/Robert Mack

Is the instrument negotiable?

What about the reference to the payment based on the sale of the ring?

What about the time for payment? Date certain?

Is this a negotiable promissory note?

Is it in writing?

Is the amount due certain or can be calculated based on the face of the instrument?

Is this Order paper?
