Background to the Transaction

On March 13, 2006, The McClatchy Company announced a definitive agreement under which McClatchy will acquire Knight-Ridder, Inc. Knight Ridder publishes 32 daily newspapers in 29 U.S. markets, with a circulation of 3.4 million daily and 4.5 million Sunday. Knight Ridder has websites in all of its markets and a variety of investments in internet and technology companies, publishes a growing portfolio of targeted publications and maintains investments in two newsprint companies. Knight Ridder’s internet operation develops and manages the company’s online properties. It is the founder and operator of Real Cities (www.RealCities.com), the largest national network of city and regional websites in more than 110 U.S. markets.

As part of that announcement, McClatchy said it planned to sell 11 of the acquired newspapers that do not fit with the company’s longstanding operating strategies and acquisition criteria, and to sell the St. Paul Pioneer Press due to anticipated anti-trust concerns involving McClatchy’s (Minneapolis) Star Tribune.

After McClatchy’s planned divestitures and the close of the Knight Ridder acquisition, The McClatchy Company will become the nation’s second-largest newspaper company measured by daily circulation (approximately 3.2 million), with 32 daily newspapers and approximately 50 non-dailies. The expanded McClatchy will own leading newspapers in many of the fastest-growing markets nationwide, with an enhanced portfolio of Internet assets. The transaction is subject to customary terms and conditions, including approval by the Knight Ridder shareholders and is expected to close this summer.

On April 26, 2006, the McClatchy Company announced a definitive agreement with MediaNews Group, Inc. (MediaNews) and The Hearst Corporation (Hearst) under which the companies will pay McClatchy $1.0 billion in cash to acquire four newspapers. MediaNews will purchase two northern California papers, the San Jose Mercury News and Contra Costa Times, and Hearst will acquire the Monterey (CA) Herald, and the St. Paul Pioneer Press in St. Paul, Minnesota.

On May 23, 2006, McClatchy announced a definitive agreement to sell Philadelphia Newspapers, Inc. (PNI) to Philadelphia Media Holdings LLC (PMH) in a transaction valued at $562 million. The purchase covers the Philadelphia Inquirer and Philadelphia Daily News, both daily newspapers, and related media assets including philly.com.

On June 7, 2006, McClatchy entered into separate definitive agreements to sell the Akron Beacon Journal to Sound Publishing Holdings, Inc., The News-Sentinel, a 75% stake in the Fort Wayne Joint Operating Agency and certain publications and web sites related to the newspaper to Ogden Newspapers, the Duluth News Tribune and the Grand Forks Herald to Forum Communications Company and the (Aberdeen) American News to Schurz Communications, Inc.
