registered investment company, and may be deemed to be a beneficial owner of
453,586 shares of Issuer's common stock owned by CREF. Teachers Advisors, Inc.
("Advisors") is the investment adviser to three registered investment companies,
TIAA-CREF Funds ("Mutual 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"), and may be deemed to be a beneficial
owner of 80,000 shares of Issuer's common stock owned by the Mutual Funds, Life
Funds and VA-1. Investment Management and Advisors are reporting their combined
holdings for the purpose of administrative convenience. These shares were

holdings and each disclaims that it is a member of a "group" with the other.
