331,200 shares of Issuer's common stock for the benefit of TIAA Real Estate
Account, a separate account of TIAA. In addition, TIAA, as the parent of a

investment discretion over 620,910 shares of Issuer's common stock that are
beneficially owned by two registered investment companies--TIAA-CREF
Institutional Mutual Funds ("Institutional Funds") and TIAA-CREF Life Funds
("Life Funds"), as well as the TIAA-CREF Asset Management Commingled Funds Trust
I ("TCAM Funds")--whose investment adviser is Teachers Advisors, Inc., a wholly
owned subsidiary of TIAA. TIAA is reporting the combined holdings of these
entities for the purpose of administrative convenience. These shares were
acquired in the ordinary course of business, and not with the purpose or effect
of changing or influencing control of the Issuer. The filing of this statement
should not be construed as an admission that TIAA is, for the purposes of
Sections 13 or 16 of the Securities Exchange Act of 1934, the beneficial owner
of these shares.
