Explanation of Responses:
(1) This Form 4 is being filed to report Mr. Dodge's purchase of an aggregate
of 250,000 shares of Class A Common Stock on the open market on March 1,
2002.
(2) The information set forth in column 5, "Amount of Securities Beneficially
Owned at End of Month" includes information, as of March 1, 2002, only with
respect to Mr. Dodge's beneficial ownership of Class A Common Stock. It
does not include information about Mr. Dodge's beneficial ownership of
shares of Class B Common Stock (which are convertible into Class A Common
Stock on a one-for-one basis) and stock options to purchase Class A and
Class B Common Stock because Mr. Dodge had no reportable transactions in
these other classes of securities during the period for which this report
is filed.
(3) Mr. Dodge disclaims any beneficial ownership in shares owned by the trusts
or his spouse.
** Intentional misstatements or omissions of facts constitute Federal Criminal
Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
