MARKETWATCH AGREES TO BE ACQUIRED BY

DOW JONES FOR $18 A SHARE

San Francisco, CA – November 14, 2004 – MarketWatch, Inc. (Nasdaq: MKTW), a leading provider of business news, financial information and analytical tools, today announced that it has signed a definitive agreement to be acquired by Dow Jones & Company, Inc. (NYSE: DJ). MarketWatch stockholders will be entitled to receive $18 per share in cash upon the closing of the acquisition. The transaction reflects an aggregate purchase price of approximately $519 million or $463 million net of MarketWatch’s $56 million in cash on hand. The acquisition is expected to close in the first quarter of 2005 and its’ completion is subject to customary closing conditions, including regulatory approval and approval of MarketWatch’s stockholders.

“Joining Dow Jones is a great next step for MarketWatch. Being part of one of the most respected media conglomerates in the world gives us a terrific platform to grow our business and compete with the largest media companies,” said Larry Kramer, Chairman and Chief Executive Officer of MarketWatch. “By combining Dow Jones’ legendary brands, infrastructure and valuable strategic alliances with MarketWatch’s award-winning newsroom and comprehensive suite of business and analytical tools, this transaction supports our mission to be the market leader in licensed and advertising supported financial news and information.”

“We welcome our new MarketWatch colleagues with great admiration for the success they have achieved and high anticipation of what we can achieve together to benefit our readers and our customers,” said Peter R. Kann, Chairman and Chief Executive Officer of Dow Jones & Company.”

Under the terms of the agreement, which was unanimously approved by the disinterested members of the Company’s Board of Directors, MarketWatch stockholders will receive a premium of approximately 7.2% based on the Company’s closing price on Friday, November 12, 2004 and approximately a 46.5% premium to the 60-day trailing average price of MarketWatch.

The agreement also provides for the payment of termination fees by each company in certain circumstances. No voting or stockholder support agreements were entered into in connection with this transaction. Further, in connection with the transaction, MarketWatch adopted a stockholder rights plan and information on this plan will be filed with the Securities and Exchange Commission. The adoption of the stockholder rights plan is not intended to preclude a superior offer for acquisition of MarketWatch, but rather to make it

difficult for any third party to interfere with any transaction approved by the MarketWatch Board of Directors. UBS Investment Bank is acting as financial advisor to MarketWatch on the transaction.
