EMC Signs Definitive Agreement to Acquire Documentum
- -- An Overview from Frank Hauck, and Rules of Engagement for Sales and Service
- ------------------------------------------------------------------------------


              WHEN COMPLETED/CLOSED ACQUISITION WILL BROADEN EMC'S
               SOFTWARE OFFERINGS, IMPROVE FUNCTIONALITY FOR EMC
                AND DOCUMENTUM CUSTOMERS, ACCELERATE ABILITY TO
                 MANAGE CUSTOMER INFORMATION ACROSS ITS ENTIRE
                                   LIFECYCLE.


OVERVIEW

EMC and Documentum have signed a definitive agreement for EMC to acquire
Documentum in a stock transaction. The definitive agreement is a crucial step
in the acquisition process, which is expected to proceed for approximately 90
days. During this period and until any final closing of a deal, EMC and
Documentum remain totally separate entities, and each will continue to serve
its own customers, and act in the marketplace just as we do today. This means
EMC sales must remain 100% focused on selling EMC's complete automated
networked storage value proposition, and the new offerings you're learning
about in the July training sessions.

EMC is pursuing this acquisition for several key reasons:

o        IT SIGNIFICANTLY ENHANCES EMC'S ILM SOLUTIONS BY EXPANDING
         CAPABILITIES INTO ENTERPRISE CONTENT MANAGEMENT FOR UNSTRUCTURED DATA

o        It will give EMC a stronger software distribution capability through
         Documentum's direct and channel sales arms

o        It will accelerate EMC's continued evolution from a platform provider
         to a provider of complete solutions comprising hardware, software and
         services

EMC is committed to supporting all customers and products, and providing, as
necessary, smooth upgrade paths to customers for new functionality across EMC
and Documentum products. When completed/closed Documentum will be a division of
EMC, with sales, marketing and development functions. Certain EMC and
Documentum products will be brought together to share development resources and
to create integrated roadmaps for customers.


SALES ENGAGEMENT REQUIREMENTS

It is important to remember that the acquisition itself has not yet occurred.
It is expected to take some time to complete, and involves many steps including
approval by Documentum shareholders. As such, SALES BEHAVIOR MUST BE `BUSINESS
AS USUAL'. This means:

o        STAY 100% FOCUSED ON SELLING THE EMC VALUE PROPOSITION AND OUR
         AUTOMATED NETWORKED STORAGE OFFERINGS.

o        DO NOT POSITION DOCUMENTUM WITH CUSTOMERS, DOCUMENTUM SALES FORCE OR
         DOCUMENTUM'S CHANNEL PARTNERS AS ALREADY ACQUIRED BY EMC. Do not
         engage the Documentum sales team or Channel partners, or position
         Documentum products directly or indirectly, in any way differently
         than you have in the past.

o        CONTINUE TO SUPPORT OUR EXISTING PARTNERSHIP WITH DOCUMENTUM TO SERVE
         CUSTOMERS AND WIN DEALS. Documentum is part of the EMC Developer's
         program, and is also a Centera partner. Leverage these relationships
         and the integration work that's been done between our offerings to
         create strong value propositions for customers.

o        DO NOT MAKE COMMITMENTS ABOUT FUTURE DEVELOPMENT EFFORTS WITH
         DOCUMENTUM, or make claims about EMC plans to eliminate, strengthen or
         merge any product sets or organizations between the companies, in
         efforts to win business.

o        CONTINUE TO ENGAGE AND WORK WITH ALL EMC PARTNERS including those who
         may have offerings similar to Documentum's. We completely support
         customers need for choices and flexibility in their solutions.

o        DO NOT DISCUSS FUTURE EMPLOYMENT WITH EMC, REPORTING STRUCTURE, ETC
         WITH DOCUMENTUM EMPLOYEES, PARTNERS, CUSTOMERS These are confidential,
         to be determined areas during our integration planning stage

IMPORTANT QUESTIONS

QUESTION:      WHAT SHOULD I TELL MY CUSTOMER?

ANSWER:        EMC continues to set the pace in the storage industry, by making
               the investments that help deliver better value for our
               customers. Documentum's solutions give us a powerful new
               solution for enterprise content management. We'll continue to
               enhance functionality, giving customers more powerful and
               completely heterogenous capabilities moving forward, and
               protecting the investments they've already made.

QUESTION:      DOES THIS MEAN EMC WILL PHASE OUT OVERLAPPING PRODUCTS?

ANSWER:        No. EMC is committing to support all customers, and provide
               smooth upgrade paths and improved functionality for all
               customers. No customer will find themselves with a `dead end'
               solution.

QUESTION:      CAN EMC SALES START SELLING DOCUMENTUM PRODUCTS?

ANSWER:        No. EMC sales needs to stay 100% focused on selling our current
               products, services and solutions. Upon closing of the deal later
               in the year, Documentum is expected to be a division of EMC, and
               to continue to have direct and channel sales arms. Questions of
               channel conflict and sales compensation will be addressed as
               discussions continue to move forward.

QUESTION:      SHOULD EMC START COOPERATING MORE FULLY WITH DOCUMENTUM SALES
               TEAMS TODAY?

ANSWER:        Sales behavior needs to be `business as usual.' Continue to take
               advantage of the existing partner relationships with Documentum,
               but no additional activities should take place.

QUESTION:      DOES THIS ACTION SIGNAL ANY CHANGE IN EMC'S STRATEGY?

ANSWER:        EMC remains focused on becoming the ultimate information
               lifecycle management company. This acquisition accelerates our
               current directions in software and product mix, and also extends
               EMC's value proposition into the high-growth enterprise content
               management space. It broadens our ability to help customers
               maximize the value of their information, at the lowest possible
               cost, across its entire lifecycle, from creation to elimination.

QUESTION:      HOW WILL DOCUMENTUM'S SALES FORCE INTERACT WITH EMC'S SALES FORCE
               ESPECIALLY THE OPEN SOFTWARE SALES GROUP ?

ANSWER:        We plan to retain Documentum's sales and distribution efforts as
               an independent sales force to insure continued focus on these
               products and services. Over time, we will leverage this
               independent selling capability to additional Open Software
               products. EMC's sales force will bring in Documentum's sales to
               support an integrated solution involving EMC and Documentum's
               products.
