The shares reported as disposed of were relinquished by the Reporting Person and cancelled by the Issuer in exchange for the Issuer's agreement to pay federal and state tax withholding obligations of the Reporting Person resulting from the vesting of restricted stock units ("RSUs"). The Reporting Person did not sell or otherwise dispose of any of the shares reported on this Form 4 for any reason other than to cover required taxes.

2. The Reporting Person serves as a co-trustee of the trust.

3. The Reporting Person serves as the trustee of the trust.

4. The Reporting Person's spouse serves as the trustee of the trust.

5. The shares are held by the Reporting Person's spouse.

7. 50% of the RSUs vest on each of March 7, 2024 and March 7, 2025, so long as the Reporting Person continues to provide services to the Issuer or any of its subsidiaries on each vesting date as provided in the Plan or the RSU Agreement. Shares of the Issuer's common stock will be delivered to the Reporting Person upon vesting. The RSUs have no expiration date.
