(See note below) (b) Percent of Class: 8.7% (c) Number of shares as to which such person has: (i) sole power to vote or to direct the vote Not Applicable (ii) shared power to vote or to direct the vote 1,196,688 (See note below) (iii) sole power to dispose or to direct the disposition of Not Applicable (iv) shared power to dispose or to direct the disposition of 1,196,688 (See note below) Note: All of the indicated shares of Common Stock are issuable upon conversion of CD Radio Inc. 5% Delayed Convertible Preferred Stock (the "5% Preferred"). The beneficial ownership of shares of Common Stock listed above represents an estimate of the number of shares of Common Stock issuable upon the conversion of shares of 5% Preferred beneficially owned, assuming a conversion date of August 29, 1997 and all dividends on shares of the 5% Preferred are added to its liquidation preference. The number of shares of Common Stock issuable upon conversion of the shares of the 5% Preferred would equal such liquidation preference ($25 plus any accrued but unpaid dividends) of the shares being converted plus any other cash payments due to the holder thereof divided by the then-effective conversion price applicable to the Common Stock (the "Conversion Price"). The Conversion Price, as of any date up to and including November 15, 1997, is determined in accordance with a formula based on market prices of the Common Stock or actual prices at which the converting holder sold the Common Stock, in either case multiplied by an amount equal to 1 minus a percentage that increases from 14.375% (at this date) monthly to 27.875% (after November 15, 1997). The actual number of shares of Common Stock issuable upon conversion of the 5% Preferred beneficially owned by the reporting person (and reported herein) is subject to change and could be materially less or more than the amount reported herein, depending upon factors which cannot be predicted at this time, including among others, application of the conversion provisions based on market prices prevailing at the actual date of conversion and whether dividends on shares of 5% Preferred are paid in cash or added to its liquidation preference.
