Richardson, Texas (March 26, 2007) — KnowledgeBase Marketing, a Wunderman company and leading provider of direct marketing services, has acquired a 51 percent interest in DATACORE Marketing. Kansas City-based DATACORE Marketing is a marketing services company with a track record of working closely with clients to develop marketing solutions that drive sales and improve marketing program ROI. Founded in 1992 by Jeff Yowell, DATACORE has amassed an impressive list of Fortune 500 companies that attest to its ability to provide a measurable return on investment for the client's marketing expenditure.

DATACORE's services combine marketing strategy, data management, program management, and reporting and analytics into an integrated marketing solution. Its business model is unique in that it combines strategic marketing, data and fulfillment services traditionally not found with a single provider. DATACORE's ability to vary the scope of its services to meet specific client needs has allowed it to compete successfully against larger competitors who lack the flexible, variable and scalable technology services of DATACORE's solutions.

"The DATACORE transaction perfectly complements KnowledgeBase Marketing's business. We have long recognized the value of helping our clients manage all activities in the marketing continuum and we, like DATACORE, are passionate about delivering measurable ROI to our clients," said Gary S. Laben, president and CEO of KnowledgeBase Marketing. "The DATACORE Marketing relationship extends our capabilities by enabling us to help clients fill the gaps in their marketing execution while managing their operational costs more effectively."

Together, KnowledgeBase Marketing and DATACORE offer the nation's marketers a powerful and expanded set of marketing services that enable them to manage their marketing activities from strategy to execution. The combination of the two companies' services and capabilities into one offering gives the clients of each company access to a deeper and broader product set. KnowledgeBase Marketing's expertise in implementing sophisticated marketing infrastructures is complemented by DATACORE's established capabilities in helping customers strategically utilize their data assets and executing support activities. This new relationship also makes the combined services available to both business-to-consumer and business-to-business marketers.

"Joining forces with KnowledgeBase Marketing allows us to present our clients with a broader range of data marketing services, such as superior data resources and advanced database marketing and analytics capabilities," said Jeff Yowell, president and CEO of DATACORE Marketing. "Additionally, we are confident our services will add value for KnowledgeBase clients. Together, we bring an end-to-end range of services to our clients. I am very excited about the opportunities that lie ahead for our clients, for us and for the entire WPP family."

Now part of KnowledgeBase Marketing, DATACORE management and staff will remain in their current positions and continue to operate from their headquarters in the Kansas City area. Jeff Yowell, president and CEO of DATACORE, will maintain 49 percent equity interest in the business and will continue to be actively involved in running the business going forward. KnowledgeBase Marketing has the option to acquire the remaining ownership in future transactions.

Frontier Partners, a division of Frontier Investment Banking Corporation, represented the management of DATACORE in this transaction.
