EMC Announces Plan to Acquire Document Sciences Corp. Leading Provider of Customer Communications Solutions

EMC Further Extends Its Enterprise Content Management Leadership and Vision with Best-in-Class Document Output Management (DOM)

HOPKINTON, Mass and CARLSBAD, Calif, Thursday, December 27, 2007 - 

EMC Corporation (NYSE: EMC), the world leader in information infrastructure solutions, and Document Sciences Corporation (NASDAQ: DOCX) today announced that they have signed a definitive agreement whereby EMC will acquire publicly-held Document Sciences Corporation in a cash transaction valued at approximately $85,000,000. Document Sciences Corporation is the market’s leading provider of document output management (DOM) software that facilitates highly personalized, multi-channel communications to customers, partners and suppliers. The acquisition complements and extends EMC’s position in the transactional content management (TCM) marketplace, the fastest-growing segment of enterprise content management.

The board of directors of Document Sciences Corporation approved the transaction with EMC based, in part, upon the recommendation of a special committee of the Document Sciences board of directors that was established to evaluate strategic alternatives. Under the terms of the agreement, Document Sciences Corporation stockholders will receive $14.75 in cash for each share of Document Sciences Corporation common stock. The acquisition is subject to customary closing conditions, including Document Sciences’ stockholder and regulatory approvals, and is expected to be completed in the first quarter of calendar year 2008. This transaction is not expected to have a material impact on EMC financial results in 2008.

Document Sciences’ xPression suite of document output management and customer communications solutions enables organizations to automate the creation and delivery of well-designed, highly personalized communications – from contracts, policies and high-volume relationship statements, to customized marketing collateral and correspondence. Leveraging xPression, Document Sciences’ customers benefit from increased customer loyalty; a single, standards-based solution that integrates with enterprise CRM, ECM and ERP systems; and dramatically improved design and implementation of business communications.

Mark Lewis, President, Content Management and Archiving Division at EMC commented, “Core to delivering high-value transactional content management (TCM) solutions is a complete suite of technology, including high-volume, content-rich task processing, sophisticated capture, business process management, records management and archiving, as well as automated document output management. The proposed acquisition of Document Sciences would make EMC the first to offer all of these major capabilities in an all-in-one, integrated suite. Building on our recent commitment to deliver end-to-end solutions to solve real-world business problems, Document Sciences provides a tremendous advantage in addressing transaction-intensive applications such as loan origination, new account enrollment, wealth management, brokerage and claims processing. This gives our customers a significant competitive edge to increase customer loyalty and maximize business performance.”

“We are pleased to enter into this transaction with EMC, which we believe provides our stockholders with an attractive value,” said Jack McGannon, president and CEO of Document Sciences. “Since our inception in 1991, our vision has been to empower organizations worldwide with dynamic content publishing solutions to realize productivity benefits, reduce costs, and increase competitiveness. Currently, more than 500 major organizations around the globe rely on Document Sciences solutions to automate the creation and delivery of highly-personalized customer communications across all channels, with more than 100 using our next-generation xPression suite for both high-volume and real-time interactive document generation. Today’s announcement with EMC enables us to take this vision one step further – providing us with the financial and technology resources of a proven leader in information management to further cement our market leadership.”

Upon completion of the acquisition, EMC intends to operate Document Sciences Corporation as a business unit within the EMC Content Management and Archiving division.
