Explanation of Responses:

( 1 )The shares reported include 2,765 shares of restricted stock subject to vesting conditions. ( 2 )On the Transaction Date, the Reporting Person exercised option shares and sold a certain number of those exercised shares to cover the tax liability flowing from those exercises, and held the remaining shares. ( 3 )The Performance-Based Stock Option was granted pursuant to the Issuer's Restated Employee Equity Incentive Plan ("EEIP") on January 1, 2018. The extent to which the options were exercisable was dependent upon the Company achieving certain compounded annual growth rate targets based on net revenue growth in Fiscal Year 2019 over Fiscal Year 2017. The determination that these options vested was made by the Compensation Committee in February 2020. Thereafter, the options become exercisable in three equal installments on March 1, 2020; January 1, 2021; and January 1, 2022. ( 4 )The Service-Based Stock Option was granted pursuant to the Issuer's EEIP on February 23, 2016. The option is scheduled to vest in five equal installments on February 23 in each of the years 2019-2023, provided that the Reporting Person remains employed by the Company on the applicable vesting dates.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
