Explanation of Responses:

1. 81,000 of the Reporting Person's limited partnership interest ("LTIP Units") in SL Green Operating Partnership, L.P. ("SLGOP"), of which the Issuer is the sole general partner, were converted into Class A Units of limited partnership interests in SLGOP ("Common Unit") and then were immediately converted into an equal number of shares of the Issuer's Common Stock.

2. Includes 1,196.80 shares of common stock purchased through the Issuer's Employee Stock Purchase Plan.

3. Represents the weighted average sale price. These shares were sold in multiple transactions at sale prices ranging from $50.26 to $50.98, inclusive. The reporting person undertakes to provide upon request by the U.S. Securities and Exchange Commission staff, the Issuer or a security holder of the Issuer, full information regarding the number of shares sold at each separate price.

4. Represents LTIP Units issued as long term incentive compensation pursuant to the Issuer's equity based compensatory programs. Conditioned upon minimum allocations to the capital account of the LTIP Units for federal income tax purposes, each LTIP Unit may be converted, at the election of the holder, into 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 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. The rights to convert LTIP Units into Common Units and redeem Common Units do not have expiration dates.
