(1)   Stripped SQUARZ can be created from SQUARZ and re-created into SQUARZ.
 
(2)   The notes may be sold as a unit with the SQUARZ of which they are a component or sold separately after they have been separated from such SQUARZ.
 
(3)   Assumes that all of the warrants underlying the SQUARZ and Stripped SQUARZ of the selling securityholder are exercised for class A common stock at a ratio of 0.1116 share of class A common stock per warrant; excludes fractional shares of class A common stock and shares of class B common stock that are issuable in lieu of fractional shares of class A common stock.
 
(4)   Assumes that all of the warrants underlying the SQUARZ and Stripped SQUARZ of the selling securityholder are exercised for class B common stock at a ratio of 3.3480 shares of class B common stock per warrant or exercised for class A common stock at a ratio of 0.1116 share of class A common stock per warrant and converted into 30 shares of class B common stock per share of class A common stock; excludes fractional shares of class B common stock.
 
(5)   Calculated pursuant to Rule 13d-3(d)(i) under the Exchange Act based on 1,303,059 shares of class A common stock and 6,959,311 shares of class B common stock outstanding as of April 30, 2003. In calculating the percentage with respect to each selling securityholder, we treated as outstanding the shares of common stock issuable upon exercise of all of the warrants underlying the SQUARZ and Stripped SQUARZ held by such selling securityholder but did not assume the exercise of any warrant by any other holder of SQUARZ or Stripped SQUARZ. Because each share of class A common stock is convertible into 30 shares of class B common stock, we treated each share of class A common stock as equivalent to 30 shares of class B common stock. Percentage for each selling securityholder reflects not only the shares of our common stock issuable to such selling securityholder upon the exercise of the warrants underlying such selling securityholder’s SQUARZ or Stripped SQUARZ but also other shares of our common stock that such selling securityholder has informed us that it beneficially owns.
