Mr. Connolly will also be paid an amount equal to $1,704,281, representing the approximate value of his unvested long-term equity incentive awards, that were due to vest in February 2024. Of that amount, $888,769 will be paid upon the Release Effective Date and the remainder will be paid during the seventh month following the Separation Date. In addition, Mr. Connolly will be paid an amount equal to $228,750, representing the value of his 2023 short-term incentive payment, at target and pro-rated for a period of six (6) months, which shall be made in one lump sum payment within thirty (30) days of the Release Effective Date.
