                                    EXHIBIT A


ITEM 5.  OWNERSHIP.

Teachers Insurance and Annuity Association of America ("TIAA") presently holds
49,900 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 two
registered investment advisers, may be deemed to have indirect voting or
investment discretion over 183,035 shares of Issuer's common stock that are
beneficially owned by five registered investment companies--College Retirement
Equities Fund ("CREF"), TIAA-CREF Institutional Mutual Funds ("Institutional
Funds"), TIAA-CREF Mutual Funds ("Mutual Funds"), TIAA Separate Account VA-1
("VA-1") and TIAA-CREF Life Funds ("Life Funds"),--whose investment advisers are
TIAA-CREF Investment Management, LLC (in the case of CREF) and Teachers
Advisors, Inc. (in the case of Institutional Funds, Mutual Funds, VA-1, and Life
Funds), 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.
