| | <footnote id="F2"> The RSUs, awarded as part of the Issuer's 2023-2025 Long Term Incentive Program, vest in three (3) equal annual installments on September 6, 2023, 2024 and 2025. </footnote> |

| | <footnote id="F4"> The PSUs, awarded as part of the Issuer's 2023-2025 Long Term Incentive Program, are subject to both performance and time vesting requirements. The number of PSUs reported represents the target number of PSUs. The number of PSUs that vest, if any, may vary from 0% to 200% of the target number reported, and is based on goals for the Issuer's compound annual total shareholder return over the three-year period from September 7, 2022 through September 6, 2025. The time vesting requirement will be satisfied on September 6, 2025. </footnote> |
