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 BXP, 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 BXP's common stock.

Footnote F2

23,981 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 BXP's common stock, in accordance with the terms of the Issuer's Partnership Agreement.
