The grant of the restricted stock units was previously reported in a Form 4 filed on May 31, 2018. ( 2 )On December 18, 2018, the Issuer issued 35,190 shares of common stock to the Reporting Persons in connection with the Issuer's exercise of an option under a Preferred Stock Option Agreement dated May 29, 2018. The Issuer previously reported this Preferred Stock Option Agreement in Table II on a Form 4 filed on May 31, 2018. Pursuant to the exercise of this option and the closing of the transactions thereunder on December 18, 2018, the Issuer acquired all 35,189,669 shares of preferred stock owned by the Reporting Persons in exchange for 35,190 shares of common stock. The common stock issued upon exercise were restricted shares. The option expired on April 30, 2020. As consideration for Reporting Persons' grant of the option, the Issuer also paid them $5,000. The sale of the preferred stock by the Reporting Persons and the issuance of common stock to the Reporting Persons upon exercise of the option by the Issuer, are transactions exempt from Section 16(b) of the Exchange Act.
