     This Schedule 13G is being filed by Twentieth Century Companies, Inc.
("TCC").  Investors Research Corporation ("IRC"), an investment advisor
registered under Section 203 of the Investment Advisors Act of 1940, is a

companies registered under Section 8 of the Investment Company Act and to
several institutional investors, IRC is deemed to be the beneficial owner of
shares of stock held by such clients.

     TCC, as a result of its control of IRC, and Mr. Stowers, as a result of
his control of TCC, are also deemed to beneficially own all such shares deemed
to be beneficially owned by IRC.  Mr. Stowers, TCC and IRC all disclaim
