Explanation of Responses:

Id	Content
F1	Represents common units of limited partnership interest ("Common OP Units") in the Issuer. Each Common OP 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 common stock of Boston Properties, Inc. ("BXP"), the Issuer's sole general partner, except that BXP may at its election, acquire each Common OP Unit so presented for redemption for one share of common stock of BXP.
F2	2,000 of the Reporting Person's units of limited partnership interest ("LTIP Units") in the Issuer were converted into Common OP Units in the Issuer by the Reporting Person and the Common OP Units were redeemed for an equal number of shares of common stock of BXP, in accordance with the terms of the Issuer's Partnership Agreement.
F3	Represents LTIP Units in the Issuer issued as long term incentive compensation pursuant to BXP'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 the Issuer 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 common stock of BXP, except that BXP may, at its election, acquire each Common OP Unit so presented for one share of BXP's common stock. LTIP Units have no expiration date.
