Warrants to purchase 511,094 shares of Class A Common Stock have not been included for the three months ended July 31, 2019. There were no warrants issued during the three months ended July 31, 2018.

There were no restricted shares excluded for the three months ended July 31, 2019 and July 31, 2018.
