(1) The stock appreciation right was previously reported as covering 112,500 shares at an exercise price of $2.81 per share, but was adjusted, (i) effective as of December 2, 2002, in connection with the Issuer's 2002 rights offering and (ii) effective as of August 23, 2004, in connection with the rights offering by Liberty Media International, Inc. ("LMI") following it's spin off from the Issuer on June 7, 2004 (the "LMI Spin Off"). The stock appreciation right became exercisable as to 20% of the total number of shares on each January 1, beginning January 1, 1997.
(2) The method used for calculating the fair market value of the Issuer's Series A common stock for the purpose of this stock option was adjusted in connection with (i) the LMI Spin Off; (ii) the distribution of Series C common stock by Liberty Global, Inc. ("LGI") on September 6, 2005, following the merger of LMI and UnitedGlobalCom, Inc. into LGI on June 15, 2005; and (iii) the spin off of Discovery Holding Company from the Issuer on July 21, 2005, in order to take into account the economic effect of those transactions.
