Explanation of Responses:
(1) This Amendment is being filed to amend the Form 4 as originally filed on
May 17, 2002 to report additional purchases occurring after May 17, 2002.
Specifically, on May 23, 2002, Mr. Dodge purchased an aggregate of 50,000
shares of Class A Common Stock on the open market. These shares are in
addition to the 150,000 shares of Class A Common Stock purchased by Mr.
Dodge over the period May 3-17, 2002, which were previously reported on the
original filing of this Form 4 on May 17, 2002.
(2) The information set forth in column 5, "Amount of Securities Beneficially
Owned at End of Month" includes information, as of May 31, 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).
