  <P>The stock options that were accelerated are all held by non-executive officers
  of the Company. Stock options awarded to the current executive officers of the
  Company on February 11, 2003 and February 10, 2004, which aggregated 754,000 and
  557,000, respectively, were not accelerated. All other terms and conditions of
  the February 11, 2003 and February 10, 2004 stock option grants are unchanged.
  No other Tribune Company stock option grants are affected. </P>
  
  <P>The accelerated vesting of these stock options is one of several actions the
  Company has recently taken to reduce stock-based compensation expense that will
  be recorded in future years with the adoption of Statement of Financial Accounting
  Standards No. 123R. Over the last two years, the Company has reduced the number
  of stock options granted by approximately 45%. The Company also reduced the
  option term from 10 to 8 years for both the 2004 and 2005 option grants
  and eliminated the replacement option feature from those grants. </P>
