Tallan was formerly known as Business Data Services (BDS). Further enhancing CMGI's focus on the business-to-business arena, the company will be integrated with CMGI Solutions, CMGI's recently launched e-Business solutions provider. The combined cash and stock transaction is valued at approximately $920 million. The transaction, subject to regulatory approvals and customary closing conditions, is expected to be completed in May 2000. Following the close of the acquisition, CMGI Solutions will integrate Tallan's capabilities in electronic commerce development, including data warehousing, data mining, and online transaction processing systems, deepening CMGI Solutions' ability to provide end-to-end e-Business consulting and implementation services for Global 2000 companies. Tallan's current client base includes some of the nation's leading web retailers, manufacturers and services companies, including EMC, Barnes & Noble, Columbia House, Priceline, Ingram Micro, eToys, Pepsi, Wit Capital, CVS, and Talbots. At launch last December, CMGI Solutions had an annualized run rate of more than $14 million dollars and has experienced rapid growth in excess of 100% per quarter. The acquisition will grow CMGI Solutions' billable resources by 350%, enabling rapid time to market and deeper expertise in a variety of e-Business applications.

"The addition of Tallan provides CMGI Solutions with the full complement of talent to meet the significant and rapidly growing demand for its products and services," said David Wetherell, Chairman and CEO of CMGI. "Our partnerships with Compaq and others have presented us with the enviable position of having far more business than we can adequately take on. Tallan is a major step in the direction of alleviating this imbalance." "Competitively, CMGI Solutions has the added advantage of greater familiarity with the full array of products and services within the growing CMGI family," added Wetherell. "More and more, major e-Business customers want to combine one or more of these services and/or products with their own vertical online applications. We are also extremely pleased with the quantity and quality of Tallan's customer base, and we could not wish for a better way to fast-forward CMGI Solutions to being a leading source in the Web systems development and integration industry." "CMGI Solutions' vision is to be the single point of contact for Global 2000 companies seeking to unlock the business value of the Internet," said Ronald Spears, president and CEO of CMGI Solutions.
