F2: Represents units of limited partnership interest in BPLP issued 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.

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 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 the Issuer's common stock. Common OP Units have no expiration date.
