SEATTLE & NEW YORK--(BUSINESS WIRE)--July 22, 2003

Tom Sperry Relocates to New York as President of Worldwide

Business Development to Expand Presence for Growing East Coast and

International Agency Clientele

Atlas DMT, an advertising technology provider and operating unit of aQuantive, Inc. (Nasdaq:AQNT), today announced two significant management changes: Ona Karasa will become chief operating officer, promoted from chief technology officer and senior vice president. Additionally, Tom Sperry will relocate to New York where he will become the company's president of worldwide business development.

"Since 2001, Atlas DMT has been providing the most effective third party ad serving and campaign management technology to agencies and advertisers, and both Tom and Ona have been essential to the rapid growth of the business," said aQuantive president Brian McAndrews. "In the relatively short time Ona has been with our company, she has showed exceptional leadership and an amazing understanding of the needs and direction of Atlas DMT and its customers. I look forward to watching her lead this business unit to the next level as its chief operating officer."

Sperry added, "Atlas DMT has had tremendous success in building a strong business and becoming a market leader in a very short period of time. Due to these accomplishments, I believe my presence in New York can even further accelerate our growth in the U.S. and worldwide. In addition, Atlas DMT is in incredible hands with Ona taking on the role as COO and leading the division. She will do a tremendous job and I look forward to working together with her to ensure the continued success of Atlas DMT."

The management changes come on the heels of Atlas DMT's continued domestic growth, successful break into the European market and the recent release of the Atlas Suite 4.0 -- the award-winning third party ad serving and campaign management platform that provides agencies with automated access to the metrics that will help translate online advertising campaigns -- now including rich media -- into results that matter most to marketers. With Sperry's move from Seattle to Atlas DMT's New York office, the company will strengthen its presence in the heart of the advertising agency market and can focus on expanding the burgeoning European market. According to a recent study by eMarketer, Inc., online advertising in Europe is projected to reach $3.77 billion by the end of 2003. Atlas DMT has already seen great success since the rollout of the Atlas Suite in the United Kingdom earlier this year, and is looking to tap into other International markets in the future.

"The European market has already proven to be an essential part of our business strategy," said Karasa. With Tom's presence in New York, we can utilize his industry experience, leadership and strong focus on management of customer relations to act as a bridge from the East coast to International markets, better positioning Atlas DMT to serve our many agency customers with multi-national offices."

Before joining Atlas DMT as chief technology officer and senior vice president of development and product services in 2002, Karasa was executive vice president and general manager of MSNBC.com, where she managed the day-to-day operations of MSNBC.com including sales, marketing, technology, finance and business partnerships. Prior to this, she served MSNBC.com as vice president of development and design, overseeing all technology groups and operations as well as the non-editorial components of the design team. Karasa has also held vice president of product development positions for Clarus Corporation, a supply-chain software company, and Atrieva, an Internet back-up software and service provider. She holds an M.A. from Bastyr University and a B.A. from Smith College in Massachusetts.

Since Atlas DMT rolled out as a separate business unit under the aQuantive corporate umbrella in 2001, Tom Sperry has led the technology division as president. For his contributions to the online advertising industry, Sperry was recently appointed chairman of the Interactive Advertising Bureau's Associate Member Board. In this role, he will lead the associate member companies working with the IAB on initiatives to improve the overall effectiveness of the interactive advertising industry.

From 1999 to 2001, Sperry served as Avenue A's senior vice president and general manager of client services. Previously, he was the managing partner of the Seattle branch of Bozell Worldwide, Inc., a marketing communications agency. As managing partner, he was responsible for direct and database marketing, brand management, and global customer relationship management strategies for Bozell, as well as such clients as Hewlett-Packard, The New York Times, and Bank of America. From 1994 to 1998, he was a co-owner and president of CF2GS, Inc., a marketing communications agency that was acquired by Bozell Worldwide, Inc.
