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
      February 28, 2002.

(2)   The information set forth in column 5, "Amount of Securities Beneficially
      Owned at End of Month" includes information, as of February 28, 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.
