                                    EXHIBIT A


ITEM 5.  OWNERSHIP.

Teachers Insurance and Annuity Association of America ("TIAA") held shares of
Issuer's common stock for the benefit of TIAA Real Estate Account, a separate
account of TIAA. TIAA no longer holds the Issuer's common stock. In addition,
TIAA, as the parent of two registered investment advisers, may be deemed to have
indirect voting or investment discretion over 190,262 shares of Issuer's common
stock that are beneficially owned by five registered investment
companies--College Retirement Equities Fund ("CREF), TIAA-CREF Mutual Funds
("Mutual Funds"), TIAA-CREF Institutional Mutual Funds ("Institutional Funds"),
TIAA-CREF Life Funds ("Life Funds") and TIAA Separate Account VA-1
("VA-1")--whose investment advisers are TIAA-CREF Investment Management, LLC (in
the case of CREF) and Teachers Advisors, Inc.(in the case of Mutual Funds,
Institutional Funds, Life Funds, and VA-1), both of which are wholly owned
subsidiaries 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.
