Explanation of Responses:
1. Represents common units of limited partnership interest in Boston Properties Limited Partnership ("BPLP"), of which the Issuer is the general partner ("Common OP Units"). Each Common OP Unit may be presented for redemption, at the election of the holder, for cash equal to the fair market value of a share of the Issuer's common stock, except that the Issuer may, at its election, acquire each Common OP Unit so presented for redemption for one share of common stock. Common OP Units have no expiration date.
2. Represents units of limited partnership interest in BPLP issued as long term incentive compensation ("LTIP Units") pursuant to the Issuer's equity based incentive programs. Conditioned upon minimum allocations to the capital accounts of the LTIP Units for federal income tax purposes, each LTIP Unit may be converted, at the election of BPLP or the holder, into a Common OP Unit. Each Common OP Unit acquired upon conversion of an LTIP Unit may be presented for redemption, at the election of the holder, for cash equal to the then fair market value of a share of the Issuer's common stock, except that the Issuer may, at its election, acquire each Common OP Unit so presented for one share of the Issuer's common stock. LTIP Units have no expiration date.
3. Includes 6,217 vested LTIP Units, 3,432 LTIP Units that will vest on January 15, 2024, 462 LTIP Units that will vest on February 3, 2024, 2,821 LTIP Units that will vest on January 15, 2025, 5,244 LTIP Units that will vest on January 15, 2026, and 4,471 LTIP Units that will vest on January 15, 2027. Also includes 1,943 LTIP Units granted pursuant to the Issuer's 2021 Multi-Year Long-Term Incentive Program (the "2021 Program") and may be earned based on the achievement of certain performance criteria based on the Issuer's total shareholder return over a three-year performance period ending on February 1, 2024 and 1,581 LTIP Units granted pursuant to the Issuer's 2022 Multi-Year Long-Term Incentive Program (the "2022 Program") and may be earned based on the achievement of certain performance criteria based on the Issuer's total shareholder return over a three-year performance period ending on January 31, 2025.
4. Any LTIP Units earned pursuant to the 2021 Program and the 2022 Program will vest in full on February 1, 2024 and January 31, 2025, respectively, with each earned LTIP Unit and Common OP Unit acquired upon conversion of such LTIP Unit subject to an additional post-vesting holding period pursuant to which such LTIP Unit and Common OP Unit generally may not be transferred, and the redemption right associated with the Common OP Unit may not be exercised, until one year after the vesting date.
