Explanation of Responses:

( 1 )Represents restricted stock unit equivalents attributable to the June 11, 2019 determination by the Compensation Committee that the performance criteria for the period of April 29, 2018 through April 27, 2019 applicable to non-derivative performance units issued on August 7, 2018 had been satisfied. Subject to continued employment of the Reporting Person through April 24, 2021, the restricted stock unit equivalents will automatically convert into shares of common stock. Because the restricted stock unit equivalents are payable solely in shares of common stock, the award is being reported on Table I. ( 2 )Represents shares of common stock indirectly held by the Report Person's Employee Stock Ownership Plan (ESOP) account through April 25, 2020. ( 3 )Options are exercisable as follows: 33% on 7/1/2020, 33% on 7/1/2021 and 34% on 7/1/2022. ( 4 )Options are exercisable as follows: one-third vesting on 6/29/2019, one-third vesting on 6/29/2020, and the remaining one-third vesting on 6/29/2021.
