The calculation of the foregoing percentage was based on 84,479,464 shares of the Issuer’s Common Stock outstanding as of February 28, 2019, as per the Issuer’s Form 10-K/A dated March 20, 2019.

Accordingly, after the Merger was completed, the reporting persons no longer beneficially owned any shares of the Issuer’s Common Stock.
