World’s Most Comprehensive Portfolio of Information Storage Solutions Broadened to

Improve Customers’ Ability to Access, Manage And Protect Information

From Inception To Archive To Disposal


HOPKINTON, Mass. and MOUNTAIN VIEW, Calif. – July 8, 2003 – EMC Corporation and LEGATO Systems, Inc., today announced a definitive agreement for EMC to acquire LEGATO, in a stock transaction valued at approximately $1.3 billion, extending EMC’s technology and market leadership in storage software. The addition of LEGATO’s strengths in heterogeneous information protection and recovery, HSM (hierarchical storage management), automated availability, and email and content management will expand EMC’s market-leading portfolio of open storage software, making it easier for customers to access, manage and protect all of their information. This move underscores EMC’s commitment to open, heterogeneous storage management, expands EMC’s capabilities around information access and recovery, and deepens EMC’s unparalleled storage management expertise and customer service and support.


Joe Tucci, EMC’s President and CEO, said, “This combination is all about improving the access, management and protection of an organization’s core asset – information – through its complete lifecycle. We’re combining best-of-breed storage technology, two winning employee populations with similar reputations for customer focus, and two experienced management teams with highly complementary visions for the future of information management. This represents a significant win for both companies’ customers, employees, partners and stockholders, accelerating the evolution of EMC as the company that offers the most comprehensive, open and integrated information storage solutions.”


The acquisition will accelerate EMC’s ability to deliver the industry’s most complete information lifecycle management solutions, helping customers get the maximum value from their information at the lowest total cost at every point in the information lifecycle. Further, LEGATO’s software-focused sales expertise, extensive channel partner relationships, and strong service capabilities will complement EMC’s distribution strategy and enhance its ability to serve customers of all sizes around the globe.


David B. Wright, LEGATO’s Chairman and CEO said, “LEGATO’s current shareholders, employees, customers, and partners will see tremendous benefits from EMC’s extensive R&D resources, expertise in networked storage, global distribution and customer reach, and overall financial strength. We will now have additional resources to further accelerate the development and delivery of

solutions to the market in order to fulfill our mission of delivering the software and services that protect and manage customer’s information, assure the availability of their applications and provide immediate access to business-critical information. This begins the next chapter for LEGATO as we expand our capabilities and continue our legacy of innovation.”


Under terms of the agreement, LEGATO stockholders will receive 0.9 of a share of EMC common stock for each share of LEGATO common stock. Based upon the EMC closing stock price of $11.74 on July 7, 2003, the transaction is valued at approximately $1.3 billion. The acquisition is subject to customary closing conditions, including LEGATO’s stockholder and regulatory approvals, and is expected to be completed in the fourth quarter of calendar year 2003. When completed, EMC expects to take an expense charge in the quarter the transaction is closed for the value of LEGATO’s in-process research and development costs. EMC expects to report a net profit in each quarter in 2003 and expects the transaction to be slightly accretive to fully diluted earnings per share in 2004.


Upon completion of the acquisition, EMC intends to operate LEGATO as a software division of EMC headquartered in Mountain View, California, led by David B. Wright, LEGATO’s current Chairman and CEO.
