Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) On March 15, 2006, Mr. Fuller entered into a Variable Prepaid Forward transaction with Credit Suisse First Boston Capital LLC relating to 480,000 shares of Class B Common Stock, which contract expires on 12/24/2008, and for which Mr. Fuller received net proceeds of $12,511,958.
(2) Under the terms of the contract, Mr. Fuller has agreed to deliver shares of Class B Common Stock (which are immediately convertible into shares of Class A Common Stock on a one-for-one basis) or shares of Class A Common Stock on the expiration date of the contract (or on an earlier date if the contract is terminated early) as follows: (i) if the Final Price is less than or equal to the Floor Price ($30.1000 per share), 480,000 shares; (ii) if the Final Price is less than or equal to the Cap Price ($37.6250 per share), but greater than the Floor Price, then a number of shares equal to 480,000 times the Floor Price divided by the Final Price; (iii) if the Final Price is greater than the Cap Price, then a number of shares equal to 480,000 shares multiplied by a fraction, the numerator of which is the sum of the Floor Price and the difference between the Final Price and the Cap Price, and the denominator of which is the Final Price.
(3) In connection with the contract, Mr. Fuller has pledged 480,000 shares of Class B common stock to secure his obligation under the contract. Under the contract, in lieu of delivery of shares, Mr. Fuller may, at his option, settle the contract by delivery of cash.
