                       EMC COMPLETES ACQUISITION OF VMware

Hopkinton, Mass., January 9, 2004 - EMC Corporation (NYSE:EMC), the world leader
in information storage and management, today announced it has completed the
acquisition of Palo Alto-based VMware, Inc., a rapidly growing, privately held
software company specializing in Intel-based virtual computing software. Under
the terms of the definitive agreement announced on December 15, 2003, EMC
acquired VMware in a cash transaction with a final value of approximately $625
million.

         VMware will play a key role in EMC's strategy to help customers lower
their costs and simplify their operations by deploying virtualization
technologies across their heterogeneous IT infrastructure to create a single
pool of available storage and computing resources. VMware's leadership in server
virtualization, together with EMC's innovation in storage virtualization, will
serve as a strong foundation for next-generation information lifecycle
management solutions.

         EMC will operate VMware as a separate software subsidiary of EMC,
headquartered in Palo Alto, California, and led by Diane Greene, VMware's former
President and CEO. The VMware name, brand and products will all be maintained,
and VMware employees will remain focused on developing, selling and servicing
VMware's products and solutions.
