LONDON, UK, 4 November 2004 - Commission Junction, a division of ValueClick, Inc. (Nasdaq: VCLK), today announced the successful expansion of its operations into Germany. The launch of Commission Junction Deutschland will strengthen Commission Junction's European presence and demonstrates the continued success of ValueClick's European expansion strategy. Commission Junction, a provider of online performance marketing solutions, 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.

Following their success in the UK and the US, Commission Junction is well positioned to succeed in Germany - Europe's largest economy. Commission Junction's solutions help marketers increase online leads and sales by facilitating strategic relationships between advertisers and publishers through an open marketplace. Commission Junction's global network offers marketers the simplicity of having one account to monitor and measure all of their online international relationships. Supported by a German language interface and local client services team, Commission Junction has already successfully penetrated the German market with new advertisers Citibank, Expedia, T-Mobile and Swarovski.

"Commission Junction is a leading global affiliate marketing company, and we are very excited by its prospects in one of Europe's strongest markets," said Carl White, ValueClick's European Managing Director. "We have an experienced and talented team in Germany and the early advertiser and publisher feedback has been fantastic."
