Explanation of Responses:

1. Represents restricted stock units granted under the UniFirst Corporation Amended and Restated 2010 Stock Option and Incentive Plan (the "2010 Plan"). Such restricted stock units vest 60% on the third anniversary of the grant date, 20% on the fourth anniversary of the grant date and 20% on the fifth anniversary of the grant date.

2. Consists of 1,044 restricted stock units that vest 100% on December 20, 2022, 1,231 restricted stock units that vest 100% on October 22, 2023 and 969 restricted stock units that vest 60% on October 29, 2022, an additional 20% on October 29, 2023 and the remaining 20% on October 29, 2024 and 709 shares of Common Stock owned by the reporting person.

3. Represents shares owned by Michael Croatti's children. Michael Croatti disclaims beneficial ownership of these reported securities, except to the extent of his pecuniary interest therein, and this report shall not be deemed an admission that he is the beneficial owner of these securities for purposes of Section 16 or any other purpose.

4. This stock appreciation right, which was granted under the 2010 Plan, becomes 60% vested and exercisable on the third anniversary of the grant date (10/29/2022), an additional 20% vested and exercisable on the fourth anniversary of the grant date (10/29/2023) and an additional 20% vested and exercisable on the fifth anniversary of the grant date (10/29/2024). This stock appreciation right must be settled in stock at the time of exercise.

Remarks:

On October 30, 2019, the reporting person filed a Form 4 to report the grant of certain restricted stock units and a stock appreciation right (the "Form 4"). The Form 4 inadvertently reported incorrect vesting terms with respect to the restricted stock units and the stock appreciation right and an incorrect number of shares of Common Stock subject to the stock appreciation right. This Form 4/A is being filed to correct the vesting terms of the restricted stock units and stock appreciation right and to report the correct number of shares of Common Stock subject to the stock appreciation right.
