            IDENTIFICATION AND CLASSIFICATION OF MEMBERS OF THE GROUP


College Retirement Equities Fund - IV
TIAA Separate Account VA-1 - IV
TIAA-CREF Mutual Funds - IV
TIAA-CREF Institutional Mutual Funds - IV
TIAA-CREF Life Funds - IV

The College  Retirement  Equities Fund,  TIAA Separate  Account VA-1,  TIAA-CREF
Mutual Funds, TIAA-CREF Institutional Mutual Funds and TIAA-CREF Life Funds (the
"Reporting  Persons") are filing as a group because CREF's  investment  adviser,
TIAA-CREF Investment Management, LLC, is affiliated and employs some of the same
investment personnel as Teachers Advisors, Inc., the investment adviser for TIAA
Separate Account  VA-1,TIAA-CREF  Mutual Funds,  TIAA-CREF  Institutional Mutual
Funds and TIAA-CREF Life Funds.  However,  because separate investment decisions
are made  with  respect  to the  respective  portfolio  holdings  of each of the
Reporting Persons and there is no oral or written agreement or arrangement among
the  Reporting  Persons  with respect to  acquisition,  voting,  disposition  or
otherwise  of their  securities,  each  Reporting  Person  disclaims  beneficial
ownership of the others'  securities  holdings and disclaims its membership in a
group  with the other  Reporting  Person,  where the  purpose of the group is to
acquire control of or influence management of the issuer.
