Explanation of Responses:

( 1 )Represents restricted stock units "RSUs" which will vest in three equal annual installments beginning on the first anniversary of March 26, 2020. ( 2 )In addition to the RSUs described in footnote 1, the Company also granted 107,143 performance-based RSUs that become subject to vesting based upon the Company's actual Adjusted EBITDA for 2020 relative to an Adjusted EBITDA goal. If a minimum Adjusted EBITDA target is not met, no RSUs will become subject to vesting. If the vesting thresholds are met, and depending upon the threshold, a minimum of 40%, and a maximum of 160%, of the RSUs subject to the award will become subject to vesting. After the number of RSUs that may become subject to vesting is determined, such number of RSUs will vest in three annual installments beginning on the first anniversary of March 26, 2020. These restricted stock units will not be included in the total of column 5 until vesting. ( 3 )Represents 5,000 shares of Common Stock and 71,429 restricted stock units that are subject to forfeiture and vesting.

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