(2) The information set forth in column 5, "Amount of Securities Beneficially Owned at End of Month" includes information, as of May 17, 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). /s/ Steven B.
