Explanation of Responses:

(1)  On April 3, 2003, a grantor retained annuity trust (the “GRAT”) distributed to the reporting person, as an annuity payment, an aggregate of 15,488,310 shares of Series B Common Stock (representing $157,748,434 in market value based on the average of the high and the low sale price of such shares on April 3, 2003).  The transfer of Series B Common Stock by the GRAT to the reporting person may be deemed to be a change in the form of beneficial ownership of the transferred shares.  (2)  Pursuant to a call agreement between the Issuer and the reporting person and his spouse, the Issuer has the right, under certain circumstances, to acquire Series B Common Stock owned by the reporting person and his spouse and their permitted transferees.  The shares transferred from the GRAT to the reporting person are subject to such right, as are the shares that remain in each GRAT.  (3)  The reporting person disclaims beneficial ownership of these shares, which are owned by his spouse.
