        <footnote id="F1">Reporting Person has elected to defer payment of Board retainer and fees pursuant to the Issuer's deferred compensation arrangement for directors. Deferred amounts (including any cash dividends credited during the previous quarter) are deemed invested quarterly in the number of Phantom Common Stock Units equal to the number of shares of Class A and Class B Common Stock that such amounts would have purchased when converted.  Phantom Common Stock Units are paid out after the Director's retirement from the Board and are settled in cash.</footnote>
