Filed by Minnesota Mining and Manufacturing Company Pursuant to Rule 425 under the Securities Act of 1933 Subject Company: Robinson Nugent, Inc. Commission File No: 000-09010 PHASE IA: INITIAL ANNOUNCEMENT 3M EXEC/REP REMARKS TO Robinson Nugent, Inc. EMPLOYEES AT GENERAL EMPLOYEE MEETINGS Thank you, (name) [Look at audience] and thank YOU for having us here. I'm John Woodworth, general manager of the 3M Interconnect Solutions Division, and I'm very excited about this announcement. Obviously, there are a number or things we can't discuss because of shareholder and regulatory approvals. But we wanted to talk to you as soon as we could, to let you know why we are so pleased to be moving forward with this transaction. We value your accomplishments. We see our corporate cultures as being complementary, in terms of innovation, and valuing people. We are confident that together, we will continue to build a very successful business in the electronic interconnect market. First, let me tell you a little bit about the 3M Interconnect Solutions Division. We provide interconnect devices primarily for telecommunications equipment, test and instrumentation equipment and other industrial and computing applications. Our products and services cover a wide range of copper and fiber connectors, cables, and cable/connector assemblies. Our customers include electronic equipment manufacturers, semiconductor manufacturers, electronic assemblers, and others in related industries. We also have a strong global distribution network. And we have one of the world's few power brand names. What attracted us to Robinson Nugent, Inc.? Let me set the stage. (Overhead: Winning 3M Strategies) We have four strategies that we think will help grow our business: 1. Provide innovative high performance interconnect solutions 2. Reach customer intimacy with industry leaders in the target segments 3. Broaden product offering through strategic alliances, JVs and acquisitions 4. Excel via industry leading service All of these apply to the potential acquisition of Robinson Nugent, Inc., but I want to focus on number three today. Before we initiated serious contact with acquisition candidates, we set these objectives: (Overhead Strategic Acquisition Objectives) 1. Accelerate profitable growth 2. Accelerate time-to-market 3. Grow our preferred vendor status 4. Infuse new product technology to our platform roadmap requirements 5. Improve our Interconnect Solutions skill sets. We feel Robinson Nugent, Inc. meets ALL of these objectives. (Overhead: Technology Platform Roadmap) [Chart comparing performance (speed in Gb/s) to time for various 3M product categories] Here's what our technology platform roadmap looks like. We're solid on the lower left end of this curve, and strong on the upper end of this, with heavy investments in fiber optics, for example. (Overhead: Roadmap w/ Robinson Nugent, Inc. Impact) [Chart comparing performance (speed in Gb/s) to time for various 3M product categories with arrows indicating products to be impacted by Robinson Nugent acquisition] Robinson Nugent, Inc. is strong and very complementary to 3M in these four areas. You can see how this illustrates the synergistic impact of Robinson Nugent, Inc. & 3M together. **[-TECHNOLOGY SYNERGY-]** 3M was interested in acquiring your company because the products are complementary as well. **[-PRODUDCT SYNERGY-]** You have solid products and technologies that we don't. You are solidly positioned with products in the marketplace, and that's something you should be very proud of. One example is your new, very high-speed hard metric platform backplane, which is among the fastest backplane interconnects on the markets. (Overhead: Product Platform Roadmap w/ circles) [Chart comparing performance (speed in Gb/s) to time for 3M and Robinson Nugent products] You can see by each of these ovals how our products fit together, and how little overlap there really is. 3M is green, Robinson Nugent, Inc. is red. Clearly, our two organizations are complementary. And you know about areas that we do not. 3M has historically focused on the wiremount side of the interconnect business. The backplane not only has market value in its own right, but it usually drives the design requirements for cable assemblies. So that's a synergy that is important for our success. We have recently moved into the fiber optics arena with a new interconnect that we are very excited about. This is an important technology that we bring to the party. As applications require more bandwidth and more people access the Internet more frequently and move increasingly larger chunks of data, fiber will solve the narrow bandwidth dilemma. So we see this as a big part of our future. With the high speed copper interconnects that you have -- which fit nicely into our strategy -- we can expand further into the telecommunications sector together. So let me state again, that, out of all the companies that are out there, when we looked at Robinson Nugent, Inc., we found: o complementary technologies o complementary products o and a synergistic customer base So we are enthusiastic at the prospect of working with you. You have a reputation for excellent products, which is well deserved, and an enviable culture of innovation. And we are excited about the prospects of joining forces with you, and successfully growing this business. What happens next? This transaction will be submitted for approval by government regulators and the shareholders of Robinson Nugent, Inc.. A proxy statement and prospectus will be prepared and mailed to shareholders of Robinson Nugent, Inc.. The proxy statement/prospectus contains important information about the transaction. The approval process can take at least eight weeks. Assuming all goes as we hope we will get together again then. Thank you again for your time. I'd like to turn it over to our Human Resources Manager, Elton Perry, now. Elton? ### PHASE IA -- POSSIBLE HR PRESENTATION OUTLINE FOR ROBINSON NUGENT, INC.

Here's what we're planning to do: We'll form an integration team, made up of Robinson Nugent, Inc. and 3M personnel.
