Commission Junction Launches in Germany; Performance Marketing Provider Strengthens European Presence and Offers Localized Version of Its Global Network Service.

SANTA BARBARA, Calif. -- ValueClick, Inc.'s (Nasdaq:VCLK) Commission Junction, a provider of advanced online performance marketing solutions, today announced the expansion of its operations into Germany. The launch of Commission Junction Germany will strengthen Commission Junction's European presence and demonstrates the continued success of ValueClick's European expansion strategy. The new Commission Junction operation becomes ValueClick's fourth business line in Germany, joining its established media business, the recently launched comparison shopping site, Pricerunner.com and the Mediaplex adserving business.

Commission Junction's expansion into Germany enables clients in both the US and Europe to leverage new global opportunities by easily and effectively engaging in international performance marketing relationships. As part of its entry into the German market, Commission Junction has launched a German language interface for its global network, CJ Marketplace, that provides local advertisers and publishers with the capability to work in their native language and currency. The localization of the CJ Marketplace eliminates traditional barriers to global trade and provides clients across diverse geographic markets with access to worldwide relationships regardless of national borders.

The European online retail market, which is forecasted to grow 42 percent from 2004 to 2005 to more than 57 billion Euros (Forrester Research, March 2004), has strong growth potential for Commission Junction. Following its successful launch in the UK in 2001, Commission Junction is well positioned to succeed in Germany -- Europe's largest economy. Supported by a local client services team, Commission Junction has already successfully penetrated the German market with new advertisers Citibank, Expedia, T-Mobile and Swarovski.

"Our German service launch marks the latest step in our ongoing efforts to increase strategic partnership opportunities and drive superior results for our advertisers and publishers," said Jeff Pullen, executive vice president of operations for ValueClick. "The talent of our experienced German team combined with the exceptional reach of the industry's largest affiliate network offers Commission Junction clients a unique international advantage."
