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.
