ITEM 8.01. OTHER EVENTS.

On June 24, 2005, pursuant to authorization by the Governance and Compensation Committee of the Tribune Company Board of Directors, the Company accelerated the vesting of certain stock options as follows:


*Date of Grant*	Total Options Accelerated	*Grant Price*	*New Vest Date*
February 11, 2003	2,352,700	$45.90	June 24, 2005
February 10, 2004	2,355,375	$52.05	June 24, 2005

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.

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.
