2.        Conversion.

(a) The Lender shall have the option, at the Maturity Date, to convert the outstanding principal of this Note into fully-paid and non-assessable shares of Oragenics common stock at a price of two dollars and fifty cents ($2.50) per share for a total of twenty thousand(20,000) shares.
