A portion of that purchase price was reflected in a $1,750,000 Amended and Restated Secured Subordinated Promissory Note ("New Note") (the principal amount of which was reduced to $1,700,000 by reason of a subsequent transfer by AM to WT of rights in certain products), and in a $1,550,000 Secured Promissory Note ("Secured Note" and collectively with the New Note, the "Notes").
