Aprimo Acquires Doubleclick's Enterprise Marketing Solutions Business Unit
Press Release

Purchase of SmartPath and Ensemble Increases Customer Base and Accelerates Strategic Growth for Enterprise Marketing Management Leader; Deal Enables DoubleClick to Sharpen its Focus on Online Marketing

INDIANAPOLIS (June 14, 2005)—– Aprimo, Incorporated, the global leader in Enterprise Marketing Management (EMM), today announced its acquisition of the enterprise marketing solutions (EMS) business unit of DoubleClick Inc. (NASDAQ: DCLK), the leading provider of solutions for marketers, advertising agencies and web publishers. The DoubleClick EMS business includes its marketing software products, SmartPath and Ensemble.

With this announcement, Aprimo extends its leading position as the number one supplier of Marketing Resource Management (MRM) software, and strengthens its standing as a top-tier supplier of high-volume business-to-consumer and business-to-business campaign management software. Aprimo’s flagship product, Aprimo Marketing™, was recently positioned in the “Leader” quadrant of Gartner’s MRM Magic Quadrant report.

This acquisition increases Aprimo’s customer base by 70, strengthens its presence in strategic industry verticals such as pharmaceuticals/life sciences, retail, and telecommunications, and complements its leadership position in the financial services, technology, media/entertainment and manufacturing sectors.

“Aprimo’s acquisition of the DoubleClick EMS business makes perfect sense,” said Bill Godfrey, president and CEO of Aprimo. “Folding these brands into the Aprimo Marketing portfolio consolidates our leadership position in the industry and immediately benefits customers and partners who want a financially strong and visionary provider of a fully integrated marketing software platform.”

In addition to SmartPath and Ensemble customers gaining access to Aprimo’s highly regarded global product support, deployment and hosting capabilities, all customers will benefit from the influx of intellectual property and technology that Aprimo will obtain as a result of this transaction. Aprimo is committed to supporting DoubleClick’s existing EMS customers, and the two companies will partner to support Data Management and DARTmail customers that are also EMS customers, including the planned integration of the products.

“The acquisition of the EMS business unit by Aprimo provides SmartPath and Ensemble customers a definitive roadmap for the future with the leading EMM provider,” said David Rosenblatt, president of DoubleClick. “Although DoubleClick believes there is enormous potential for the EMS business, this deal gives us the opportunity to return to our roots by focusing our entire technology business on online marketing, and it ensures our EMS customers will benefit from the corresponding focus that Aprimo has on Enterprise Marketing Management.”

DoubleClick recently announced that it signed a definitive agreement to be acquired by an affiliate of the private equity firms of Hellman and Friedman LLC and JMI Equity. The sale of the EMS business unit is separate from that transaction, which is expected to be completed in the third quarter of 2005.

Aprimo corporate headquarters will remain in Indianapolis. With the acquisition, the company will increase its global workforce to 175 employees. International headquarters will remain in the U.K.
