As a result of the amendment of the Convertible Promissory Note and the completion of the Public Offering, each of BRPI and BRPLP were deemed to have disposed to the Issuer their respective portions of the derivate security represented by the Convertible Promissory Note in exchange for the issuance by the Issuer of a derivative security represented by the Convertible Promissory Note as amended to reflect the $0.75 conversion price, which security was immediately thereafter converted for the underlying shares of Issuer common stock.</footnote>
