INTRODUCTION Welcome to the first issue of the MergerMe Newsletter, a publication designed to keep you up-to-date regarding our progress toward becoming the new Pentair! You can expect to see a few issues of the MergerMe Newsletter prior to Day 1. In addition to this newsletter and other periodic communications, the MergerMe microsite on our respective intranets (The Well and Synergy) is the central source for all merger-related information. On Day 1, there will not be dramatic changes for most aspects of your daily work at the new Pentair. This is to allow leaders and subject matter experts to fully understand the strengths and best practices of both legacy organizations. We will work towards SCadopting the best of both organizations and to create a better new Pentair together. Full integration will take time, and we will ask for your input, support, and feedback often along the journey. IN THIS ISSUE: Introduction 1 PIMS 1 Randy Hogan Visits Middle East 2 Case Studies 3 IST Update 4 Did You Know? 4 Top FAQ’S 4 MergerMe Reminder 4 PIMS DRIVES RESULTS AT PENTAIR PROVEN SUCCESS WITH PIMS You don’t have to spend much time at Pentair before you hear the acronym PIMS. The System Pentair Integrated Management drives performance improvement every day, providing the processes, methods and tools Pentair uses for continuous improvement. PIMS strengthens the company’s capabilities as a company and offers the opportunity to share best practices with each other around the globe. PIMS has four key components (1) the Rapid Growth Process (RGP) for accelerating organic growth; (2) new product development process for accelerating innovation, referred to as 3D; (3) Pentair Talent System for attracting and developing top talent; and (4) Lean Enterprise methodology for eliminating waste across the Pentair enterprise. Rapid Growth Process. RGP is Pentair’s process for driving sustainable, repeatable double-digit growth across the enterprise. The process starts with a strategic plan that outlines our growth vision for the business. Once the plan has been outlined, each business develops growth concepts that capitalize on the opportunities available with key customers, markets, geographies, or channels. RGP then offers a set of tools that take the concept through a series of rapid tests including Alpha, Beta and Launch phases. The Rapid Growth process is intended to allow a much faster reaction time and better deployment of resources by quickly identifying those ideas with great potential as well as eliminating those with critical flaws early in the process.

While the Rapid Growth Process works to develop growth concepts or business solutions, 3D works in concert to bring new products to market. The process includes three key phases. Starting with the Design phase, 3D incorporates Voice of the Customer throughout to assure that our developments have the greatest opportunity for market success. The second “D”, Develop, incorporates design for manufacturing and Six Sigma tools to control cost and error-proof development. Finally, the Deploy phase enables a look ahead to plan the successful rollout into the marketplace. Talent Management. Pentair’s growth vision requires that the company has a full pipeline of bright, dynamic and well trained individuals to help build the Pentair of the future. The talent management process is designed to select develop and retain the very best people in key industries . This structured approach which has been in place for several years assures that the company has the right human resources in place to support strategies for growth, technological innovation, and operating excellence. Lean Enterprise. The primary goal of Lean Enterprise is to eliminate waste and improve velocity across all of business processes. Though originally deployed in manufacturing, lean has shown tremendous potential to improve speed and reduce non value-added work . The goal of course, is providing value to our customers, and the Lean toolkit includes tools to do just that. With the key metrics of SQDCC (safety, quality, delivery, cost and cash), lean assures that we provide maximum benefit to all stakeholders including shareowners, customers, employees, and the communities in which the company operates. SPECIAL INTEREST: RANDY HOGAN VISITS TYCO GULF IN MIDDLE EAST Earlier this summer, Pentair Chairman and CEO Randy Hogan visited a number of Tyco Flow Control facilities around the world, including the Middle East, three Houston locations (Stafford valve manufacturing, Thermal Controls headquarters and Valves & Controls offices) and the Fasini and Vanessa facilities in Italy. On July 11 and 12, Hogan visited Tyco Flow Control’s Middle East manufacturing and sales operations. The Middle East is an exciting growth market centering on energy, specifically oil and gas, water, process along with major infrastructure projects. Hogan visited the Emirates Techno Casting (ETC) Foundry and Tyco Gulf Valve Operations located in Sharjah, United Arab Emirates. Hogan, an engineer by training, enjoyed spending time on the floor of the state of the art facility which manufactures valves and seeing the world class foundry. “The relationships Tyco Flow Control has with the energy sector create an exciting opportunity for the new Pentair,” said Hogan. “We’ll be able to start with true scale in the energy and water markets and I’m excited about being able to build the new Pentair using the strength of the Tyco Gulf.” In addition to touring the facility Hogan joined Tyco Flow employees at a Town Hall meeting. “We were quite excited about the potential of what we saw and were impressed by the TFC colleagues we had the opportunity to meet,” said Hogan. Tyco has been a long-established leader in the Middle East, with a strong presence that spans more than three decades. It has worked on some of the most important projects in the region and Tyco Flow Control has approximately 1,100 employees at Tyco Gulf. “The Tyco relationships Flow Control sector has with create the energy an exciting for the new opportunity Pentair.” – Randy Hogan, Chairman and CEO MERGERME: YOUR SOURCE FOR MERGER INFORMATION | AUGUST 2012 2

SNOW OR WATER: INNOVATION TO MEET CUSTOMER NEEDS Whether creating winter in the summer or making summer cooler, the new Pentair will be a global water, fluid process, thermal management and equipment protection company with industry-leading products and solutions. These case studies are just two examples of the innovation expertise and customer focus that each of the companies will bring to the new Pentair. CASE STUDY: TYCO FLOW CONTROL: SUMMER SNOW FOR UK ALPINE VILLAGE Turning summer into winter takes inventive thinking and the discipline to execute on a large scale. That’s why Alpine Ski Village chose a range of Tyco Flow Control’s Keystone valves and actuators. Certified to operate at temperatures as low as -15.5 degrees Celsius, the components are at the heart of the UK’s biggest indoor, real snow ski village. The products perform an important role in the operation of the blast coolers, which are positioned around the slopes of Alpine Ski Village. At night, when the ambient air temperature within the closed complex is lowered to -6 degrees C, a mixture of compressed air and chilled water is fired into the air, which then falls as snow. During the day when the centre is open, the temperature is maintained at around -1.5 degree C. Typical snow depth on the slopes is around 400mm. This £31m development will include the UK’s longest – and the world’s widest – real snow indoor ski slope (180 meters long and 100 meters wide at the base). It will also feature a climbing wall, a cresta-inspired luge run and a children’s winter wonderland. Key to building client confidence, the Tyco Flow Control team was able to document its products’ compatibility with low temperature operation. Something that a number of other potential suppliers were unable to do, Tyco Flow Control was able to provide this assurance as a matter of course. CASE STUDY: PENTAIR: ECO FRIENDLY SOLUTIONS FOR KEEPING COOL Pentair is committed to developing environmentally responsible products. As the global leader in pool and spa equipment, we deliver customer focused solutions that save energy, conserve water and reduce noise with our Eco Select line of pool products managed by Pentair’s Aquatic Systems global business unit. The Eco Select line includes many products with one thing in common: they all contribute to protecting our environment. The IntelliFlo and IntelliPro pool pumps reduce energy costs by up to 90 percent. Several innovations make this possible, including magnet motors (used in hybrid cars) and custom programming of functions to reduce speed. These pumps are also the quietest running pumps ever built. The many Eco products Select line with includes one contribute thing in common: to protecting they all our environment. Another product that provides a dramatic reduction in energy costs is the UltraTemp Heat Pump. It transfers heat from the atmosphere to the pool or spa, saving up to 80 percent in energy costs compared to other types of heaters. Automatic pool cleaners are also successful products in this line. The Kreepy Krauly Prowler robotic cleaner offers fast, eco-friendly cleaning and requires no installation, booster pump or hoses. Its auto-reverse feature helps prevent hang-ups near corners, steps and ladders. Among the many additional products in this line are LED pool and spa lights that last longer than traditional halogen or incandescent lights, minimizing replacement cost and disposal, and control systems that automate and synchronize equipment scheduling to offset rising utility costs. Also offered is the D.E. (Diatomaceous Earth) filter. It provides efficient water flow that allows the use of smaller pumps or lower pump speeds to minimize energy use. Whether it’s maintenance equipment, a filter, pump, heater, pool cleaner or light, every product in the line fulfills Pentair’s commitment to providing customers with environmentally sound products.
