Explanation of Responses:

1. On June 17, 2020, the reporting person was granted 83,333 restricted share units ("RSUs"), vesting in three equal annual installments beginning on the first anniversary of the grant date. Each RSU represents a conditional right to receive a cash payment equal to the fair market value of one share of common stock of the Issuer (a "Common Share") or, at the Issuer's discretion, a number of Common Shares equal to the number of vested RSUs (or a combination of cash and Common Shares). One-third of the RSUs vested on June 17, 2021 and were converted into Common Stock on a one-to-one basis at the Issuer's discretion.
