Explanation of Responses:

( 1 )Each Performance Restricted Stock Unit ("PSU") represents a contingent right to receive one (1) share of Issuer's common stock. ( 2 )On January 28, 2022, the Reporting Person filed a Form 4 which inadvertently omitted to report in Table II certain PSUs acquired upon determination by the Board of Directors of the Issuer that the performance conditions were met with respect to PSUs granted to the Reporting Person on March 12, 2020. The shares vest on January 26, 2023, subject to the Reporting Person continuing as a service provider through such date. The Reporting Person is amending the January 28, 2022 Form 4 to include this information in Table II.

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