                                    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. In addition, TIAA, as the parent of two registered investment
advisers, may be deemed to have indirect voting or investment discretion over
124,420 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"), as well as the TIAA-CREF Asset Management Commingled
Funds Trust I ("TCAM Funds")--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, VA-1 and TCAM 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.
