Adams, by fraudulent representations, induced Barton to purchase one hundred shares of the capital stock of the Evermore Oil Company. The shares were worthless. Barton executed and delivered to Adams a negotiable promissory note for $5,000, dated May 5, in full payment for the shares, due six months after date. On May 20, Adams indorsed and sold the note to Cooper for $4,800. On October 21, Barton, having learned that Cooper now held the note, notified Cooper of the fraud and stated he would not pay the note. On December 1, Cooper negotiated the note to Davis who, while not a party, had full knowledge of the fraud perpetrated on Barton. Upon refusal of Barton to pay the note, Davis sues Barton for $5,000. Is Davis a holder in due course or does he have the rights of a holder in due course? Explain.
