Explanation of Responses:

1. Conditioned upon minimum allocations to the capital accounts of the LTIP Units for federal income tax purposes, each vested LTIP Unit may be converted, at the election of the holder, into a Class A Unit of limited partnership interest in SL Green Operating Partnership, L.P. (a "Common Unit"). Each Common 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 Unit so presented for one share of Common Stock. LTIP Units are generally not convertible without the consent of the Issuer until three years from the date of the grant. The rights to convert LTIP Units into Common Units and redeem Common Units do not have expiration dates.

2. Reflects forfeiture of 65,066 LTIP Units previously issued pursuant to the SL Green Realty Corp. 2014 Long-Term Outperformance Plan (the "2014 Plan") due to the fact that the performance-based vesting criteria under the 2014 Plan were not satisfied.

3. Represents 56,000 LTIP Units granted in connection with the automatic one year extension of the term of the employment agreement between the reporting person and the Issuer dated November 8, 2013, as amended.

4. The LTIP Units will vest on December 31, 2018, subject to continued employment.
