 EMC ANNOUNCES FRAMEWORK FOR DATA GENERAL INTEGRATION, APPOINTS KEY EXECUTIVES

HOPKINTON, Mass. - October 18, 1999 - EMC Corporation, the world's leading
provider of intelligent enterprise storage systems, software and services,
today announced the framework for a rapid integration of the newly acquired
Data General Corporation. EMC's acquisition of Data General was completed
October 12.

         Michael C. Ruettgers, EMC President and CEO, named two senior EMC
executives to lead the transition:

         FRANK M. HAUCK has been named Senior Vice President and DG
Integration Leader, responsible for overseeing the swift and efficient
integration of Data General's worldwide operations. Hauck is a nine-year
EMC veteran who has held a series of senior management positions in EMC's
customer service organization, most recently as Senior Vice President,
Global Customer Service. Joseph F. Walton succeeds Hauck as EMC's Senior
Vice President, Global Customer Service.

         ROBERT M. DUTKOWSKY has been named President of Data General, a
division of EMC that will operate as an independent unit and be responsible
for developing, manufacturing, marketing, selling, and servicing the AViiON
line of server products. Dutkowsky joined EMC in 1997 and has spent the
past two years as Executive Vice President, Markets & Channels, responsible
for EMC's worldwide sales, marketing and services operations. His extensive
industry background includes 20 years at International Business Machines
Corporation in a number of roles, including Vice President of Worldwide
Sales and Marketing for IBM's RS/6000 business. Ruettgers will assume
Dutkowsky's prior EMC duties on an acting basis.

         EMC also announced that Ronald L. Skates, former Data General
President and CEO, will assist during the transition and will retire from
the company shortly thereafter.

         "The acquisition of Data General enhances EMC's future prospects
in several important ways," said Ruettgers. "We are gaining an expanded
market opportunity, leadership midrange storage, network-attached storage
and high-end server technology, a large and loyal customer base, and a
talented workforce to help support our rapidly growing worldwide needs.
With the appointment of two of our most experienced senior executives, we
look forward to executing a clean and swift transition and realizing the
full potential of the opportunities before us."

EMC CLARIION: LEADERSHIP MIDRANGE STORAGE

The CLARiiON storage business will be integrated into EMC, under Hauck's
direction, bringing the world's best midrange storage technology to a far
larger global customer base through EMC's industry-leading sales and
service organizations. The midrange storage market opportunity was
estimated to be $10 billion in 1998. CLARiiON systems already have a large
presence in this market, with more than 100,000 units installed worldwide.

         "Many customers like the idea of a single strategic storage
partner as the foundation for their information infrastructure," said
Ruettgers. "The CLARiiON products complement our high-end Symmetrix
Enterprise Storage systems and software, enable us to strengthen our
presence outside the data center, and extend the reach of EMC technology to
all of our customers' online information needs. Information-intensive
businesses can now be even more confident and secure in this: If it's
online, chances are it's on EMC."

DATA GENERAL AVIION: LEADERSHIP HIGH-END NT SERVERS

EMC's Data General division will focus on profitable growth opportunities
for high-end Windows NT systems and NT consolidation opportunities,
leveraging Data General's NUMA technology in the fastest-growing segments
of the server market. The division also will continue to support the
roadmap of DG/UX and the worldwide installed base of Data General Unix
customers.

         "We see outstanding potential for the AViiON server business,"
said Dutkowsky. "Just as EMC pioneered the concept of storage
consolidation, there is a clear opportunity to make Data General the world
leader in the high-end NT server consolidation market. As Microsoft rolls
out Windows 2000 with its high-end features, Data General can play a
leading role in meeting customer needs with its NUMA technology,
pre-packaged `In-a-Box' solutions, and other major advancements now under
development." According to International Data Corporation, Data General was
the market leader in high-end NT servers in 1998, with the leading market
share position in both the $25,000-$250,000 and $100,000-$250,000 price
segments.

         Dutkowsky continued, "By re-focusing Data General on selected
growth segments, further leveraging its NUMA and DG/UX technologies, and
extending AViiON's leadership position in delivering a scalable, total
computing solution in the high-end NT server arena, we believe we can turn
Data General into a vibrant, profitable business unit."

         Ruettgers concluded, "EMC has a strong, results-oriented culture
driven by speed, time-to-market and a sense of urgency in everything we do.
These values will be at the forefront of our integration process as we
evaluate the opportunities for synergy and efficiency."
