(1)   Assumes that any other holders of Notes, or any future transferees, pledges, donees or successors of or from any such other holders of Notes, do not beneficially own any Class A common stock other than the Class A common stock issuable upon conversion of the Notes at the initial conversion rate.
 
(2)   Assumes conversion of all of the holder’s Notes at a conversion price of approximately $25.9680 per share of Class A common stock. However, this conversion price will be subject to adjustment as described in the Prospectus under “Description of Notes — Conversion Rights.” As a result, the number of shares of Class A common stock issuable upon conversion of the Notes may increase or decrease in the future.
 
(3)   Calculated based on Rule 13d-3(d)(1)(i) of the Exchange Act using 17,317,145 shares of Class A common stock outstanding as of May 31, 2002. In calculating this amount, we treated as outstanding the number of shares of Class A common stock issuable upon conversion of all of that particular holder’s Notes. However, we did not assume the conversion of any other holder’s Notes.
