Explanation of Responses:

1. Transaction represents a gift by the reporting person to the Sotirios Vahaviolos January 2023 2-Year Grantor Retained Annuity Trust (GRAT). Dr. Vahaviolos has retained an interest in the value of the original principal contribution to the GRAT and will receive annuity payments which may be in shares If the GRAT retains the shares. Any shares retained by the GRAT after annuity payments will be distributed to the beneficiaries of the GRAT upon its termination in two years. Dr. Vahaviolos' daughter, who does not reside with him, is the trustee for the GRAT and will hold sole power over the voting and disposition of the shares held by the GRAT. Dr. Vahaviolos and the GRAT trustee have agreed that the GRAT will be subject to the issuer's insider trading compliance policy regarding the shares held by the GRAT.

Remarks:

Dr. Vahaviolos has voluntarily elected to report this transaction on a Form 4 around the time of this gift transaction rather than wait until after the end of the year and report the transaction on a Form 5.
