Explanation of Responses:

1. These securities are restricted stock units, each representing a contingent right to receive one share of common stock, par value $0.01 per share, of the issuer. These restricted stock units were granted under the issuer's equity incentive plan and will vest in three equal installments beginning on March 1, 2022.

2. These securities are performance-based restricted stock units for the performance period from January 1, 2019 to December 31, 2021 that were granted under the issuer's equity incentive plan on March 1, 2019. All of these performance-based restricted stock units vested as of December 31, 2021 upon certification by the issuer's compensation committee of the applicable performance conditions on February 21, 2022.

3. The issuer withheld shares of common stock that would have otherwise been issuable to the reporting person to satisfy the issuer's tax withholding obligations in connection with the vesting and settlement of the performance-based restricted stock units granted on March 1, 2019 and vested upon certification by the issuer's compensation committee on February 21, 2022. The number of shares of common stock withheld was determined based on the closing price per share of the issuer's common stock on February 28, 2022.

4. The issuer withheld shares of common stock that would have otherwise been issuable to the reporting person to satisfy the issuer's tax withholding obligations in connection with the vesting and settlement on March 1, 2022 of the third tranche of the time-based restricted stock units granted to the reporting person on March 1, 2020. The number of shares of common stock withheld was determined based on the closing price per share of the issuer's common stock on February 28, 2022.

5. The issuer withheld shares of common stock that would have otherwise been issuable to the reporting person to satisfy the issuer's tax withholding obligations in connection with the vesting and settlement on March 1, 2022 of the second tranche of the time-based restricted stock units granted to the reporting person on March 1, 2021. The number of shares of common stock withheld was determined based on the closing price per share of the issuer's common stock on February 28, 2022.

6.

The number of shares of common stock withheld was determined based on the closing price per share of the issuer's common stock on February 28, 2022.
