Under the terms of the Merger Agreement, at the closing of the Acquisition, the Issuer issued to the former stockholders of Private Aceragen shares of Common Stock and shares of its Series Z Non-Voting Convertible Preferred Stock, par value $0.01 per share (the “Series Z Preferred Stock”), which was a newly designated convertible series of preferred stock, each share of which was convertible into 1,000 shares of Common Stock. Additionally, under the terms of the Merger Agreement, all issued and outstanding warrants to purchase shares of Private Aceragen’s capital stock were assumed by the Issuer and converted into warrants to purchase shares of Common Stock and Series Z Preferred Stock on substantively the same terms and conditions that applied to such warrants immediately prior to the Acquisition. Pursuant to the Merger Agreement, and in exchange for the outstanding Private Aceragen warrants held by NovaQuest, NovaQuest received a warrant to purchase (i) 1,343,547 shares of Common Stock and (ii) 14,115 shares of Series Z Preferred Stock.
