     The marketing campaign "Call Stars" is geared to enhance baseball fans'
 awareness of XM's comprehensive coverage of Major League Baseball. XM airs
 every MLB game for every team from Opening Night to the World Series.
     Fans can visit the web site to send a
 customized voice message from the New York Yankees' Jeter, Boston Red Sox
 slugger Ortiz, or Hall-of-Fame-bound Ripken. When fans arrive at the site,
 they choose a ball player and enter a friend's name, favorite team,
 hobbies, and other details. Friends will receive the voice message on their
 phone, email or by AOL Instant Messenger.
     "Call Stars" offers the baseball fan a wide variety of choices for
 creating a personal message from Jeter, Ortiz, or Ripken. Messages from
 Ortiz are available in Spanish or English. This campaign marks the first
 time that this type of audio service has been available in Spanish.
     "With baseball season underway, XM is truly thrilled to provide fans an
 interactive way to get excited about the game," said Vernon Irvin, Chief
 Marketing Officer at XM. "This viral marketing campaign engages fans in a
 way that is fun and effective, and it provides XM an ideal platform to
 communicate directly to consumers."
     In addition to carrying the games, XM has the nation's only 24-hour
 talk radio channel dedicated to Major League Baseball, MLB Home Plate (XM
 Channel 175). The channel covers every aspect of the sport 365 days a year
 with call- in shows, round-the-clock news updates, specials, and classic
 games. Ripken, who will be inducted into the National Baseball Hall of Fame
 in July, hosts the XM show "Ripken Baseball" on MLB Home Plate with his
 brother and fellow major league veteran Billy Ripken.
     XM also offers Spanish play-by-play game coverage and baseball talk on
 the channel MLB En Espanol (XM Channel 174).
