(1) These shares were acquired pursuant to the Agreement and Plan of Merger (the "Merger Agreement") among the Issuer, Rexahn, Corp and the wholly-owned subsidiaries of the Issuer, whereby each share of Rexahn, Corp's common stock was converted into the right to receive five shares of the Issuer's common stock.
(2) These options were acquired pursuant to the Merger Agreement, whereby each outstanding option of Rexahn, Corp was converted into five options to purchase shares of Issuer common stock. Such new option is otherwise subject to the same terms of the original option, except that the exercise price per share of Issuer common stock under the Issuer option is equal to the exercise price per share of Rexahn, Corp common stock under the original option, divided by five (rounded up to the nearest hundredth of a cent; provided, however, that in no event is the exercise price per share of any Issuer common stock less than $.0001).
(3) The options vest and become exercisable as to 30% of the options on January 20, 2006; another 30% of the options on January 20, 2007; and the remaining 40% of the options on January 20, 2008.
