SEATTLE, Washington . November 17, 2008 . EMC Corporation (NYSE:EMC), the world leader in information infrastructure solutions, today established Decho Corporation (www.decho.com), a new company focused on helping people protect, manage and enrich the ever-growing quantity of personal digital information in their lives, also known as an individual.s .digital echo.. Decho will be a combination of two formerly separate EMC businesses . Mozy, Inc. and Pi Corp. Decho will continue to offer consumers and businesses the top-rated MozyTM-branded online backup service (www.mozy.com), as well as introduce new cloud-based services for individuals over time.

The personal information once stored in albums, boxes and filing cabinets.such as financial records, personal documents, family photos and videos, portfolios of professional work, and correspondence.comprises each person.s digital echo. This information is increasingly scattered across different computers, digital devices and web sites. The quantity of personal digital information produced every year around the world is now measured in the hundreds of billions of gigabytes and is expected to continue to grow annually by almost 60 percent, according to analysts. Moreover, the lifespan of this information is beginning to be measured in decades, and it is ever more valuable and often irreplaceable.

The shift of personal information from physical to digital has not yet been accompanied by a parallel shift in the way this information is organized and preserved in digital form. Decho will help individuals take full control of their digital echo through a set of cloud-based services that will enable easy and full utilization, organization and enrichment of important personal information.

"There is an immense, untapped business opportunity as personal information management inevitably migrates into the cloud," said David Goulden, EMC Executive Vice President and Chief Financial Officer. "By bringing Mozy and Pi together to form Decho as a new subsidiary, we are creating a focused organization that can deliver on the promise of cloud-based personal information management and can help individuals everywhere preserve, manage and enrich the information most important to them."

Decho's initial service offering is the Mozy online backup service, the leading online backup service for both consumers and businesses. With over 900,000 users and over 25,000 business customers, Mozy safeguards over 10 petabytes (over ten million gigabytes) of customer information at its datacenters around the world. Mozy online back up offers the most comprehensive online backup solution on the market, and offers simple, automatic and secure online backup for both consumers and businesses, with support for laptops, desktops and servers running either Mac OS X or Windows.

Decho is wholly owned by EMC, which acquired Mozy, Inc. in October 2007 and Pi Corp. in February 2008. Pi was originally founded by Paul Maritz, who was named CEO of VMware earlier this year. The new company will maintain and grow its development and operations centers in Bangalore, Montreal, Seattle and Utah. The company will be headquartered in Seattle.

HOPKINTON, Mass., and SEATTLE, Wash. - Feb. 21, 2008 - EMC Corporation, the world leader in information infrastructure solutions, today announced it has signed a definitive agreement to acquire Seattle-based Pi Corporation, a privately-held developer of software and provider of services for personal information management. With approximately 100 engineers located in the U.S., Canada and India, Pi develops software and online services to enable individuals to control how they find, access, share and protect their increasing volumes of digital information. Pi is in the process of beta testing its first products.

Joe Tucci, EMC President, Chairman and CEO, said, "The proliferation of information in the hands of consumers, businesses and organizations of all sizes has brought about massive digital information growth on a scale never imagined. As the leading provider of information infrastructure, we are positioned to set a new standard for organizing, accessing and deriving value from this information. Pis technology is very complementary to our emerging cloud infrastructure strategy. Paul Maritz and his team will provide invaluable vision and leadership as we position EMC at the leading edge of cloud computing and personal information management."

Upon completion of the acquisition, Pi founder and CEO Paul Maritz, will join EMCs executive management team as President and General Manager of the newly formed Cloud Infrastructure and Services Division. Reporting to Joe Tucci, Maritz will continue to directly oversee development and operations for Pi, along with other key elements of EMCs cloud computing strategy, which include the EMC Fortress SaaS infrastructure, the Mozy online backup service and other upcoming EMC cloud infrastructure systems and software offerings under development. Pi will operate as an independent subsidiary of EMC and will continue expanding operations in its Seattle headquarters and other offices in Montreal, Canada, and Bangalore, India. Prior to founding Pi, Maritz spent 14 years working at Microsoft where he had broad development and marketing responsibilities and was a member of the Executive Committee that managed the overall company.

Maritz said, "By uniting the Pi team with a global technology leader like EMC, we'll be ideally positioned to realize our vision of allowing consumers and corporate information workers to create, repurpose, store, share and access personal information in novel ways, taking advantage of the ubiquity of computing power and a new interconnected world."

The acquisition of Pi will be an all-cash transaction and is expected to be completed in the first quarter of 2008. On a GAAP basis, EMC currently expects the acquisition of Pi will be dilutive by $.01 per diluted share in 2008. No further details of the transaction are being disclosed.
