EXHIBIT A

IDENTITY AND ITEM 3 CLASSIFICATION OF A SUBSIDIARY OF
PARENT HOLDING COMPANIES


     This  Schedule  13G is being  filed by  American  Century  Companies,  Inc.
("ACC").  American Century Investment  Management,  Inc. ("ACIM"), an investment
advisor registered under Section 203 of the Investment  Advisors Act of 1940, is
a  wholly-owned  subsidiary of ACC. Mr. James E. Stowers,  Jr.,  controls ACC by
virtue of his beneficial ownership of a majority of the voting stock of ACC.

     As a result of its status as investment advisor to six investment companies
registered  under  Section  8 of the  Investment  Company  Act  and  to  several
institutional  investors,  ACIM is deemed to be the beneficial  owner of and has
the sole  authority to dispose of and vote certain  shares (the "Shares") of the
outstanding common stock of Applied Materials, Inc. (the "Issuer").

     ACC, as a result of its control of ACIM,  and Mr.  Stowers,  as a result of
his control of ACC, are also deemed to  beneficially  own all such shares deemed
to be  beneficially  owned  by ACIM.  Mr.  Stowers,  ACC and  ACIM all  disclaim
beneficial ownership of the Shares.

     The ownership of one investment  company client of ACIM,  American  Century
Mutual  Funds,  Inc.  ("ACMF"),  formerly  totalled  more  than 5% of a class of
securities of the Issuer.

     This  Schedule 13G is being filed by ACC on behalf of ACC,  ACIM,  ACMF and
Mr. Stowers.
