Entegris’ products and systems are used to purify, protect and transport critical materials used in the semiconductor and microelectronics manufacturing processes, and in doing so help increase productivity and enhance yields. These products include: wafer carriers and shippers that protect the semiconductor wafer from contamination and breakage; filtration products that purify process gases and liquids, as well as the ambient environment; liquid systems, components and containers that dispense, control or transport process fluids; and shippers and trays for protecting and transporting devices and disk drive components. Entegris primarily sells direct, and its customer base includes virtually every maker of semiconductor devices, wafers and semiconductor fabrication equipment, as well as manufacturers of electronics such as disk drive components and flat panel displays. WHAT IS MATERIALS INTEGRITY MANAGEMENT? Materials integrity management is the process of purifying, protecting and transporting critical materials as they go through manufacturing and become high-technology products. Entegris delivers these critical materials as pure or purer than when manufactured. SOLVING THE CONTAMINATION CHALLENGES THAT ENABLE THE NEXT GENERATION OF ELECTRONICS As the semiconductor industry moves down the technology roadmap to produce smaller and more powerful devices, the need for Entegris’ materials integrity management products and services increases. Whether it is the lithography, wet etch and clean, or CMP process, contamination issues at the 65 nanometer and 45 nanometer technology generations are becoming more difficult to solve than ever before, and have a greater impact on semiconductor production yields. Today, contamination is measured and controlled on a molecular and nano level. To help enable tomorrow’s electronics, Entegris is on the forefront of providing comprehensive microcontam- ination control solutions to the semiconductor and microelectronics industries in North America, Europe, Asia and Japan. FISCAL 2006 SALES BY REGION Sales from Continuing Operations: $678.7 million North America 29% Europe 16% Asia 33% Japan 22% 57543_Letter_1-4.qxp 3/23/07 4:16 PM Page 1 A LETTER TO OUR SHAREHOLDERS This was the first full year of the new, combined Entegris operating as one company, following the 2005 merger of Mykrolis and Entegris. The integration process was demand- ing, yet ultimately successful. As a team, we integrated both predecessor companies on time, on budget and in a way that enabled our customers to continue operating with the knowl- edge that their tools, fabs and processes would be supported by dedicated and well-trained professionals. We also exceeded our initial estimates of annual integration savings, to more than $20 million. All in all, 2006 was a good year for Entegris. Sales from con- tinuing operations increased 15 percent from the prior year on a comparable, pro forma basis. Reflecting cost controls and the impact from the integration savings, modified SG&A expenses as a percentage of revenue declined in each quarter of 2006 – from 26.2 percent in the first quarter to 21.7 percent in the fourth. Operating income, excluding amortization and integration costs, was $111.2 million, or 16.3 percent of sales. Entegris also generated operating cash flow of nearly $100 million during 2006, all of which was applied to an acceler- ated $100 million stock repurchase program. We also continued to make strategic investments in new prod- uct and technology development – spending $39 million for that purpose in 2006. By year-end, we had begun to see the fruits of this investment. Most exciting are the new products – such as our LiquidLensTM ultrapure water systems for use in immersion lithography and, more recently, our Clarilite Certified products, services and systems for controlling reticle haze – that are providing critical contamination control solu- tions for our global customers. Our suite of Clarilite solutions, in particular, leverages the combined strengths gained from the merger. No other company in the world is as focused on contamina- tion control in semiconductor and advanced electronics production environments as Entegris. Moreover, many more products are in development and will fuel our future growth as they are introduced into the market in 2007 and beyond. During the first half of 2006, we successfully met the pressing demands of integration, a buoyant semiconductor equipment market and the need to get closer to our customers, while also reducing costs by shifting some production and infrastructure to Asia. Along with this success came some challenges. Certain manufacturing inefficiencies impacted our margins in the third and fourth quarters. Through our proactive efforts, however, we identified and addressed these inefficiencies, strengthened our operational processes and organization and entered 2007 with increased strength and confidence. ALIGNING OUR INTERESTS In the current business environment there is intense focus on management compensation. Consequently, I believe it is important to summarize how the senior leadership team at Entegris will be compensated for 2007. Our short-term variable compensation is heavily based on two factors – the company’s profits as a percentage of revenue and our relative revenue growth as measured against that of twenty peer and customer companies. Our long-term compensation is heavily dependent on return on invested capital. In short, how well we perform for you, our shareholders, is directly tied to how we’re compen- sated – which further aligns our interests and yours. The semiconductor and electronics industry environment in which we operate is one of the most scrutinized on the planet. Ratios, margins and capacity utilization are analyzed and reanalyzed as portents of changes in industry momentum. At Entegris, we harbor no illusions about our ability to impact these macro-industry factors. At the same time, it is apparent to us that – due to a variety of possi- ble factors, from consolidation in the equipment and device-making indus- try to the increasing role of global foundries – demand fluctuation over the recent past has exhibited some- what muted cycles compared to earlier periods. As a company, we are convinced of the following simple fact: the value of our company is best expressed as the present value of future cash flows. With this comes a commitment to maximizing our return on invested capital as well as growth. GOALS FOR 2007 This brief letter is accompanied by others from incoming chief financial officer Greg Graves, chief operating officer Jean- Marc Pandraud and chief administrative officer Bertrand Loy. Together, they will highlight the 2006 financial and opera- tional aspects of Entegris and their goals for 2007. These goals revolve around three pillars – Teamwork, Execution and Strategy – and can be summarized as follows: • Achieve our target revenue from new products and further streamline our new product development process • Leverage our manufacturing operations and increase efficiencies • Move even closer to our customers in both technology and physical proximity • Utilize our financial position to increase shareholder returns • Continue to nurture and develop our talent With 2007 already well under way, I am pleased with the start we have made toward achieving these goals and look forward to reporting to you on our progress next year. I’d like to close this letter with special thanks to the nearly 3,000 Entegris employees. We as a company are the sum of the capabilities, focus, energy and drive of many dedicated people around the world. We also owe thanks to our cus- tomers around the world for relying on us to solve their microcontamination control needs. Finally, we’d like to thank you, our shareholders, for your ongoing interest and support. We look forward to continuing to deliver value to you in this and future years. Sincerely, Gideon Argov President and Chief Executive Officer 57543_Letter_1-4.qxp 3/22/07 2:22 PM Page 2 Dear Shareholder: In my letter to you last year, I said that 2006 would be a year of building bridges for Entegris. Now, with 2007 well under way, I’m pleased to report that we accom- plished that goal – successfully uniting two organizations and reaching out to customers across the globe. For 2006, our revenue growth reflected the strong performance of the side of our business driven by capital spending, which accounted for 41 percent of the company’s total sales. Sales of such capital-driven products as our gas microcontamination and liquid systems grew faster than the overall rate of market growth. The unit-driven side of our busi- ness, which represented 59 percent of sales this year, is linked to production levels and factory utilization rates in the semiconductor industry. Sales of these products, such as our liquid filters and data storage shipping products, were robust. Geographically, sales in Asia, Japan and Europe were strong, while sales in North America were flat. While the year’s second half didn’t live up to the bullish predictions of some industry analysts, our sec- ond-half revenues exceeded the year’s first half. So 2006 was a year of building; in 2007 we expect to reap the benefits of that building through a seamless interaction between our Global Supply Chain (GSC), Entegris’ business units and our global regions. The business units and regions form our customer-facing organization, and GSC (comprising Entegris’ manufac- turing, quality and logistics functions) provide the supporting infrastructure to the organization. With this model, we’ll continue to optimize that infrastructure dur- ing the year to deliver superior value to our customers. In addition, to ensure the long-term success of Entegris, we are developing our leaders and managers so that they will perform extremely well in an environment that’s conducive to building a successful company over the long term. We’ve empowered our leaders to act like entrepreneurs – taking responsibility for the perform- ance of their businesses, while at the same time leveraging the resources of the company’s overall technology portfolio. In 2007, we intend and expect to achieve our targeted financial results in both revenue and profitability, and to focus on maximizing our return on invested capital. One goal is to grow our revenue faster than our peers, and to that end we have instituted business-unit plans geared toward achieving $40 million in revenue from new products in 2007. Each of our businesses will use a streamlined new product development process that will bring greater financial and strategic discipline to our operations. In the marketplace, the capital investment by our cus- tomers in lithography equipment is expected to outgrow the industry. At 193 nanometer wavelengths, airborne molecular contamination is a significant industry chal- lenge affecting both optics and photochemical resists. Customers are realizing that contamination issues are extremely costly both in terms of quality and productiv- ity – and are turning to Entegris for solutions such as our new Clarilite Certified systems specifically designed to eliminate reticle haze. In 2008 and beyond, Entegris will continue to pursue opportunities that help us extend our leadership in bringing innovative solutions to the semiconductor industry and in solving micro and molecular contamina- tion issues. Those opportunities will come through a mix of acquisition, partnership and organic development. Our strategy calls for us to take a twofold approach to business development. The first is to develop a core expertise relating to a specific component or consum- able, and to establish a leading cost position through operational efficiency and scale. We call that “owning the box,” and prime examples include our leadership in wafer carriers and shippers. The second is to develop a core expertise around a specific application or process step such as CMP, photolithography and wet etch and clean applications, and then to deliver the right set of components to address that application more effectively than the competition. We call that “surrounding the step.” We believe this approach brings us closer to the customer and enables us to leverage our knowledge in materials science and separations technology. Our business unit technology roadmaps are geared toward one or both of these strategies, and are closely aligned with the needs of key customers in our industry. We believe this gives us an excellent platform to trans- late our technology and market leadership into clear product differentiation, higher margins and improved market share that ultimately lead to greater share- holder value. We’re confident that by both “owning the box” and “surrounding the step” we can expect to achieve much on your behalf in 2007 and beyond. Sincerely yours, Jean-Marc Pandraud Executive Vice President and Chief Operating Officer 57543_Letter_1-4.qxp 3/22/07 2:22 PM Page 3 Dear Shareholder: In 2006, Entegris delivered solid financial performance and return to our shareholders. Our sales of $678.7 mil- lion from continuing operations grew 15 percent from the prior year on a pro forma basis adjusted for the calen- dar year change. Earnings per diluted share were $0.46 on GAAP basis and $0.63 on a non-GAAP basis adjusted for merger-related and other restructuring costs. The company’s operating margin was 16.3 percent of sales, on an adjusted non-GAAP basis. This demon- strates our ability to control operating expenses and the favorable effect of the merger-related cost syner- gies, which offset the impact of some manufacturing inefficiencies on gross margins in the third and fourth quarters. For all of fiscal 2006, Entegris generated $96 million in cash from operations, and completed a $100 million accelerated stock buyback. We ended the year in an excellent financial position with $275 million in cash, cash equivalents and short-term investments and virtu- ally no long-term debt. As is often the case, there’s a story behind the numbers. Fiscal 2006 was centered on completing the merger integration process while meeting customer demand during an industry ramp in the first half of the year. From a financial perspective, we achieved several key goals including: • Integrating the merged Entegris and Mykrolis – combining two ERP information systems into a single unified platform • Selling our discontinued operations, in February 2006 • Streamlining our physical infrastructure through facility consolidations Moving from 2006 to 2007, our focus has shifted from integration to optimization. From a financial stand- point, this means achieving three key goals: First, we will work to find new and better ways to lever- age the financial and management reporting systems that drive our decision making. Second, finance will play an active role in helping to optimize our manufacturing cost structure and also ensuring that we achieve maximum operating leverage from our global infrastructure. Third, we plan to use our balance sheet and cash flows to continue to build shareholder value – the $100 million stock buyback we implemented in 2006 and the remaining $50 million repurchase authorization being representative examples. I am pleased and excited to serve as the new CFO of Entegris. We are the market leader in products that are indispensable to our customers, and are well-positioned to capitalize on major changes in our industry in ways that foster profitable growth. I thank CFO John Villas, who is leaving the company after 23 years of outstand- ing service, for his many contributions and for making the CFO transition a smooth one. Sincerely, • Implementing an effective planning process for the combined organization Greg Graves Senior Vice President and Chief Financial Officer We experienced manufacturing challenges at certain North American facilities that impacted gross margins. As the incoming CFO, I was part of a team that under- took an in-depth review during the fourth quarter of each of our manufacturing facilities. We took several aggressive corrective actions, such as implementing improved procedures and check points, that we believe will minimize the likelihood of such issues going forward. We intend to continue to make regular reviews a key priority to leverage the strengths of our manufacturing operations. 57543_Letter_1-4.qxp 3/22/07 2:22 PM Page 4 Dear Shareholder: A key goal of Entegris’ operations is to manage and optimize the flow of raw materials, work-in-process and finished goods between our many locations and our trading partners (both suppliers and customers). Another is to manage and optimize information, cash and process/work flow. Operational excellence in these areas provides the foundation upon which Entegris’ success depends. From an operations standpoint, 2006 proved to be an exceptionally busy year, as we completed a sig- nificant range of merger-related projects while managing the com- plexities associated with an upturn in demand. By the end of 2006, we had: • Reduced our manufacturing footprint by 25 percent, moving several significant product lines in the process • Improved the company’s quality metrics • Re-launched Lean/Six Sigma initiatives • Started redeploying manufacturing assets to Asia, including closing a facility in Germany and opening one in Malaysia • Rolled out a common global ERP platform • Improved delivery performance to our customers While there were challenges, we were encouraged by the way Entegris responded to them. During the second half of the year, we identified a number of internal inef- ficiencies and dealt with them in a very proactive and deliberate way. With these efforts, we believe we are well on our way to greater operational excellence. Significant new technologies, made real and supported by superior operational performance, are the key to consistently being ahead of the competition. Thomas Edison once said, “Genius is one percent inspiration, and 99 percent perspiration.” Perspiration is our ability to consistently execute and deliver on our objectives, week after week, month after month, and deliver supe- rior returns to our shareholders. This will continue to be our main focus in 2007. As we plan for the future, the Entegris team will focus on the basic tenets of operational excellence: • Emphasizing quality in everything we do • Leading the Lean/Six Sigma way • Simplifying and strengthening our core processes and better integrating them with those of our trading partners • Establishing the critical metrics by which we want to measure our progress and promote accountability To reach these goals, we will continue to invest in our people, as no team and no individual can ever acquire too much skill and knowledge. To compete and thrive as a global corporation, we need to embrace the fast- paced technological changes that are sweeping our industry and capitalize on them. A prime example is our adoption of Lean/Six Sigma at all levels of the company. We believe it will provide our teams with tools and mindsets to efficiently face up to the many challenges and demands of the semiconductor industry and of globalization. Another important strategic initiative revolves around outsourcing more components of our supply chain to improve flexibility and increase our ability to handle the volatility of semiconductor demand cycles. By focusing on our core manufacturing capabilities, we will increase our agility and overall return on invested capital through gained efficiencies. Lastly, the semiconductor industry has long been driven by the fast growth of the Asian markets. Today, more than 55 percent of Entegris’ revenues are generated in the Asia Pacific region, and that’s conservative given that many of the tools built by U.S. and European OEM businesses will ultimately be used in Asia. But 70 per- cent of Entegris’ manufacturing capacity is U.S.-based. Over the next three years, one of our main goals is to rebalance this ratio, and we anticipate that ultimately no more than 50 percent of our manufacturing assets will be in North America. As a global organization, we will best achieve our operational and financial objec- tives if we think and plan centrally, manufacture our products regionally and support our customers locally. To that end, we will transform Entegris to more closely match the changing market landscape. I believe that the challenge facing many organizations is not the lack of well-thought-out strategies, but the lack of disciplined execution. As a company, we deliv- ered on the merger-related goals that we set; going forward, we will adhere to the principles and strategies above, and deliver superior operational and financial performance. Our team looks forward to the challenge and to establishing a foundation upon which Entegris will deliver the highest possible customer and share- holder value.

SIGNIFICANT DEVELOPMENTS The Company was incorporated in Delaware in June 2005 in connection with a strategic merger of equals transaction between Entegris, Inc., a Minnesota corporation (Entegris Minnesota), and Mykrolis Corporation, a Delaware corporation (Mykrolis). Effective August 6, 2005, Entegris Minnesota and Mykrolis were each merged into the Company with the Company as the surviving corporation to carry on the combined businesses. For more information concerning the history of our predecessor companies see “Our History” below. 1 On December 13, 2005, the Company’s board of directors approved a change in fiscal year end from a 52-week or 53-week fiscal year period ending on the last Saturday of August to December 31. As a result of this change, during 2005 the Company had a four-month transition period following the end of its prior fiscal year, running from August 28, 2005, through December 31, 2005. As a result, the financial periods presented in the Company’s consolidated financial statements appearing starting at page F-1 below cover the following periods: (i) the year ended December 31, 2006 covering the twelve months ended December 31, 2006; (ii) the four-month transition period covering the four months ended December 31, 2005; (iii) the year ended August 27, 2005 covering the twelve months ended August 27, 2005; and (iv) the year ended August 28, 2004 covering the twelve months ended August 28, 2004. Certain financial data included in the following discussion of the Company’s business is shown for twelve-month periods ended December 31, 2006, 2005 and 2004 and is presented on a pro forma combined basis. On August 21, 2006, the Company’s Board of Directors authorized a share repurchase program of up to $150 million over the succeeding 12 to 18 months. In connection with this share repurchase program the Company entered into an Accelerated Share Repurchase Agreement (ASRA) and a Collared Accelerated Share Repurchase Agreement (CASRA) with Goldman, Sachs & Co. (GS) effective August 30, 2006. Under the ASRA the Company acquired 4,677,268 shares of common stock on September 5, 2006 from GS for $50.0 million. The transaction was accounted for as a share retirement resulting in a reduction of common stock, paid-in capital and retained earnings. Under the CASRA, the Company paid GS $50.0 million for a prepaid forward contract to repurchase the Company’s common stock and received an initial minimum delivery of common stock of 2,976,444 shares on September 5, 2006. The Company received an additional 1,226,456 shares of common stock on October 6, 2006. The CASRA transaction was accounted for as a share retirement resulting in a reduction of common stock, paid-in capital and retained earnings. INDUSTRY BACKGROUND Semiconductors, or integrated circuits, are the building blocks of today’s electronics and the backbone of the information age. The market for semiconductors has grown significantly over the past decade. This trend is expected to continue due to increased internet usage and the continuing demand for applications in data processing, wireless communications, broadband infrastructure, personal computers, handheld electronic devices and other consumer electronics. The semiconductor materials industry is comprised of a wide variety of materials and consumables that are used throughout the semiconductor production process. The extensive and complex process of turning bare silicon wafers into finished integrated circuits is dependent upon a variety of materials used repeatedly throughout the manufacturing process, such as silicon, chemicals, gases and metals. The handling and purification of these materials during the integrated circuit manufacturing process requires the use of a variety of products, such as wafer shippers, wafer transport and process carriers, liquid and gas filters and purifiers, fluid and gas handling components and integrated circuit trays. Semiconductor unit volume is the primary driver of the demand for certain of these materials and products because they are used or consumed throughout the production process and many are replenished or replaced on a regular basis. Demand for other products such as wafer transport and process carriers and equipment products are driven primarily by capacity expansion. The manufacture of semiconductors is a highly complex process that consists of two principal segments: front-end processes and back-end processes. The front-end process begins with the delivery of raw silicon wafers from wafer manufacturers to semiconductor manufacturers and requires hundreds of highly complex and sensitive manufacturing steps, during which a variety of materials, including chemicals and gases, are introduced. We offer products for each of the primary front-end process steps which are listed below as well as our traditional businesses that provide products to transport in-process wafers between each of these steps. Deposition. Deposition refers to placing layers of insulating or conductive materials on a wafer surface in thin films that make up the circuit elements of semiconductor devices. The two main deposition processes are 2 physical vapor deposition, where a thin film is deposited on a wafer surface in a low-pressure gas environment, and chemical vapor deposition, where a thin film is deposited on a wafer surface using a gas medium and a chemical bonding process. In addition, electro-plating technology is utilized for the deposition of low resistance conductive materials such as copper. The control of uniformity and thickness of these films through filtration and purification of the fluids and materials used during the process is critical to the performance of the semiconductor circuit and, consequently, the manufacturing yield. Chemical Mechanical Planarization (CMP). CMP flattens, or planarizes, the topography of the film surface to permit the patterning of small features on the resulting smooth surface by the photolithography process. Semiconductor manufacturers need our filtration and purification systems to maintain acceptable manufacturing yields through the chemical mechanical planarization process by filtering the liquid slurries, which are solutions containing abrasive particles in a chemical mixture, to remove oversized particles and contaminants that can cause defects on a wafer’s surface while not affecting the functioning of the abrasive particles in the liquid slurries. In addition, manufacturers use our consumable PVA roller brushes to clean the wafer after completion of the CMP process to prepare the wafer for subsequent operations. Photolithography. Photolithography is the process step that defines the patterns of the circuits to be built on the chip. Before photolithography, a wafer is pre-coated with photoresist, a light sensitive film composed of ultra- high purity chemicals in liquid form. The photoresist is exposed to specific forms of radiation, such as ultraviolet light, electrons or x-rays, to form patterns which eventually become the circuitry on the chip. This process is repeated many times, using different patterns and interconnects between layers to form the complex, multi-layer circuitry on a semiconductor chip. As device geometries decrease and wafer sizes increase, it is even more critical that these photoresists are dispensed on to the chip with accurate thickness and uniformity, as well as with low levels of contamination, and that the process gases are free of micro-contamination so that manufacturers can achieve acceptable yields in the manufacturing process. Our liquid filtration and liquid dispense systems play a critical role in assuring the pure, accurate and uniform dispense of photoresists on to the wafer. In addition, our gas micro-contamination systems eliminate airborne amine contaminants that can disrupt effective photolithography processes. Etch and Resist Strip. Etch is the process of selectively removing precise areas of thin films that have been deposited on the surface of a wafer. The hardened photoresist protects the remaining material that makes up the circuits. During etch, specific areas of the film not covered by photoresist are removed to leave a desired circuit pattern. Similarly, resist strip is a process of removing the photoresist material from the wafer after the desired pattern has been placed on the wafer. Emerging advanced etch and resist strip applications require precisely controlled gas chemistries and flow rates in order to achieve precise etch and resist strip characteristics. Our gas filters and purifiers help assure the purity of these process gas streams. Wet Cleaning. Ultra-high purity chemicals and photoresists of precise composition are used to clean the wafers, to pattern circuit images and to remove photoresists after etch. Before processes such as photoresist coating, thin film deposition, ion implantation, diffusion and oxidation, and after processes, such as ion implantation and etch, the photoresists must be stripped off, and the wafer cleaned in multiple steps of chemical processes. To maintain manufacturing yields and avoid defective products, these chemicals must be maintained at very high purity levels without the presence of foreign material such as particles, ions or organic contaminants. Our liquid filters and purifiers are used to assure the purity of these chemicals. Our wafer and reticle carriers are high purity “mini-environments” which carry wafers between each of the above process steps protecting them from damage and contamination during these transport operations. Our fluid handling components assure the delivery of pure liquid chemicals to each of these process steps. Front end wafer processing can involve hundreds of steps and take several weeks. As a result, a batch of 25 fully processed wafers, the maximum number of wafers that can be transported in one of our products, can be worth several million dollars. Since significant value is added to the wafer during each successive manufacturing step, it is essential that the wafer be handled carefully and precisely to minimize damage. Thus, in the case of wafer 3 carriers, precise wafer positioning, highly reliable and predictable cassette interface dimensions and advanced materials are crucial. The failure to prevent damage to wafers can severely impact integrated circuit performance, render an integrated circuit inoperable or disrupt manufacturing operations. Our material integrity management products enable semiconductor manufacturers to: minimize contamination (semiconductor processing is now so sensitive that ionic contamination in certain processing chemicals is measured in parts per trillion); protect semiconductor devices from electrostatic discharge and shock; avoid process interruptions; prevent damage or abrasion to wafers and materials during automated processing caused by contact with other materials or equipment; prevent damage due to abrasion or vibration of work-in-process and finished goods during transportation to and from customer and supplier facilities; and eliminate the dangers associated with handling toxic chemicals. Once the front-end manufacturing process is completed, finished wafers are transferred to back-end manufacturers or assemblers. The back-end semiconductor manufacturing process consists of test, assembly and packaging of finished wafers into integrated circuits. Our traditional microenvironment products, such as wafer shippers, wafer and reticle carriers and integrated circuit trays, facilitate the storage, transport, processing and protection of wafers through these front-end and back-end manufacturing steps. Semiconductor manufacturing has become increasingly complex in recent years as new technologies have been introduced to enhance device performance and as larger wafer sizes have been introduced to increase production efficiencies. This increasing complexity of semiconductor devices has resulted in a number of challenges including the need for more complex, higher-precision liquid and gas delivery, measurement, control and purification systems and subsystems in the front-end manufacturing processes and to improve time-to-market, reduce manufacturing costs, improve production quality and enhance product reliability and long-term service and support. To address these challenges, semiconductor equipment companies and device manufacturers are outsourcing the design and manufacture of liquid delivery, measurement, control and purification systems, subsystems, components, and consumables to us and to other well-established subsystem and component companies that have worldwide presence and leading technologies. The design and performance of those liquid delivery systems, subsystems, components and consumables are critical to the front-end semiconductor manufacturing process because they directly affect cost of ownership and manufacturing yields. We continually seek opportunities to work with our customers to address these challenges. Also in response to these challenges and to achieve continued productivity gains, semiconductor manufacturers have become increasingly focused on materials integrity management solutions that enable them to safely store, handle, process and transport critical materials throughout the manufacturing process to minimize the potential for damage or degradation to their materials and to protect their investment in processed wafers. The need for efficient and reliable materials integrity management is particularly important as new materials are introduced and as 300 mm semiconductor wafer manufacturing becomes a more prevalent manufacturing technology. Processing 300 mm wafers, currently the largest wafer size in a manufacturing environment, is more costly and more complex because of the larger size of these wafers. In addition, new materials and circuit shrinkage create new contamination and material compatibility risks, rendering 300 mm wafers more vulnerable to damage or contamination. These trends will present new and increasingly difficult shipping, transport, process and storage challenges. We seek to bring our advanced polymer manufacturing and advanced tool design capabilities to bear on these challenges to provide our customers with innovative materials integrity management solutions. A key emerging market is the outsourced fab services market, which consists of logistics management, spares and refurbishment, consumables and information technology. The market for outsource services remains largely untapped, as currently these activities are performed primarily by the owners of fabs. A rapidly growing segment within this market is materials integrity management services, which includes sub-micron cleaning and certified re-use and recycling of materials management products. As the materials integrity management market continues to grow, we believe that there is an increasing need for more effective and efficient application of solutions through dedicated, outsourced service offerings. 4 Many of the processes used to manufacture semiconductors are also used to manufacture flat panel displays, magnetic and optical storage devices and fiber optic cables for telecommunications, resulting in the need for similar filtration, purification, control and measurement capabilities. We seek to leverage our products and expertise in serving semiconductor applications to address these important market opportunities. OUR BUSINESS STRATEGY Our objective is to be a global leader providing innovative materials integrity management solutions to the semiconductor and ancillary markets. We intend to build upon our position as a worldwide developer, manufacturer and supplier of liquid delivery systems, components and consumables used by semiconductor and other electronic device manufacturers to grow our business in these and other high value-added manufacturing process markets. Our strategy includes the following key elements: Comprehensive and Diverse Product Offerings. The semiconductor manufacturing industry is driven by rapid technological changes and intense competition. We believe that semiconductor manufacturers are seeking process control suppliers who can provide a broad range of reliable, flexible and cost effective products, as well as the technological and application design expertise necessary to deliver effective solutions. Our comprehensive product offering enables us to meet a broad range of customer needs and provide a single source of flexible product offerings for semiconductor device and capital equipment manufacturers as they seek to consolidate their supplier relationships to a smaller select group. In addition, we believe manufacturers of semiconductor tools are looking to their suppliers for subsystems that provide more integrated functionality and seamlessly communicate with other equipment. We believe our offering of consumables and equipment, as well as our ability to integrate them, allows us to provide advanced subsystems. Diversified Revenue Stream. We target a diversified revenue stream by balancing our sales of wafer transport and process carriers as well as component and subsystem equipment products with sales of our unit driven and consumable products. Our unit driven and consumable products provide a relatively more stable and recurring source of revenue in an otherwise cyclical industry. Our capital expense driven products, which are generally dependent upon such factors as the construction and expansion of semiconductor manufacturing facilities and the retrofitting and renovation of existing semiconductor facilities, position us to benefit from increases in capital spending that is typically more subject to the volatility of industry cycles. Technology Leadership. With the emergence of smaller and more powerful semiconductor devices, and the deployment of new materials and processes to produce them, we believe there is a need for greater materials integrity management within the semiconductor fabrication process. We seek to extend our technology by developing advanced products that address more stringent requirements for greater purification, protection and transport of high value added materials and for contamination control, fluid delivery and monitoring, and system integration. We have continuously improved our products as our customers’ needs have evolved. For example: we have developed proprietary materials blends, for use in our wafer handling product family which address the contamination concerns of advanced semiconductor processing below 100 nanometers; we have also developed a next generation 300 mm front opening unified pod utilizing those materials targeting the needs of 65 nm production; and we have expanded upon our proprietary two-stage dispense technology with integrated filtration for photoresist delivery, where the photoresist is filtered through one pump and precisely dispensed through a second pump at a different flow rate to reduce defects on wafers. Strong Customer Base. We have established ongoing relationships with many leading original equipment manufacturers and materials suppliers in our key markets. These industry relationships have provided us with the opportunity for significant collaboration with our customers at the product design stage which has facilitated our ability to introduce new products and applications that meet our customers’ needs. For example, we work with our key customers at the pre-design and design stage to identify and respond to their requests for current and future generations of products. We target opportunities to offer new technologies in emerging applications, such as copper plating, chemical mechanical planarization, wet- dry cleaning systems and photolithography. We believe that our large customer base will continue to be an important source of new product development ideas. 5 Global Presence. We have established a global infrastructure of design, manufacturing, distribution, service and support facilities to meet the needs of our customers. In addition, we may expand our global infrastructure, either through acquisition or internal development, to accommodate increased demand or we may consolidate inefficient operations to optimize our manufacturing and other capabilities. For example, we have established sales and service offices in China in anticipation of a growing semiconductor manufacturing base in that region. As semiconductor and other electronic device manufacturers have become increasingly global, they have required that suppliers offer comprehensive local repair and customer support services. We realigned our regional structure in September 2006, transferring customer support and logistics to local regions in an effort to enhance our global customer contact and awareness. We maintain our customer relationships through a combination of direct sales and support personnel and selected independent sales representatives and distributors in North America, Asia, Europe and the Middle East. Ancillary Markets. We plan to leverage our accumulated expertise in the semiconductor industry by developing products for applications that employ similar production processes that utilize materials integrity management, high purity fluids and integrated dispense system technologies. Our products are used in manufacturing processes outside of the semiconductor industry, including the manufacturing of flat panel displays, fuel cell components, high-purity chemicals, photoresists, solar cells, gas lasers, optical and magnetic storage devices and fiber optic cables. We plan to continue to identify and develop products that address materials integrity management and advanced materials processing applications where fluid management plays a critical role. We believe that by utilizing our technology to provide manufacturing solutions across multiple industries we are able to increase the total available market for our products and reduce, to an extent, our exposure to the cyclicality of any particular market. Strategic Acquisitions, Partnerships and Related Transactions. We plan to pursue strategic acquisitions and business partnerships that enable us to address gaps in our product offerings, secure new customers, diversify into complementary product markets or broaden our technological capabilities and product offerings. As the dynamics of the markets that we serve shift, we will re-evaluate the ability of our existing businesses to provide value added solutions to those markets in a manner that contributes to achieving our objectives; in the event that we conclude that a business is not able to do this, we expect to restructure or replace that business. Our decision to divest three product lines in late 2005 and early 2006 was made pursuant to this strategy. Finally, we are continuously evaluating opportunities for strategic alliances and joint development efforts with key customers and other industry leaders. OUR PRODUCTS Our product portfolio includes four major categories of products: microenvironment products, liquid microcontamination control products, liquid subsystem products and gas micro-contamination products. These product categories fall into two major product classes: unit driven and consumable products, and capital spending driven products. Liquid micro-contamination control products are primarily unit driven and consumable products. Microenvironment products, liquid subsystem products and gas micro-contamination products include both unit-driven and consumable products as well as capital spending driven products. Unit driven and consumable products, including service revenue, accounted for approximately 59%, 60% and 56% of our net sales for calendar years 2006, 2005 and 2004, respectively, and capital expense driven products accounted for approximately 41%, 40% and 44% of our net sales for the calendar years 2006, 2005, and 2004, respectively. There follows a detailed description of each of these four categories of products: Microenvironment Products Our microenvironment products preserve the integrity of wafers, reticles and electronic components at various stages of transport, processing and storage. Our microenvironment products fall into two sub-categories, wafer handling and finished electronic component products. 6 WAFER HANDLING PRODUCTS. We believe that we are a leading provider of critical shipping products that preserve the integrity of raw silicon wafers as they are transported from wafer manufacturers to semiconductor manufacturers. We lead the market with our extensive, high volume line of Ultrapak ® and Crystalpak ® products which are supplied to wafer manufacturers in a full range of sizes covering 100, 125, 150 and 200 mm wafers. We also offer a full-pitch front opening shipping box or FOSB for the transportation and automated interface of 300 mm wafers. We offer a complete shipping system, including both wafer shipping containers as well as secondary packaging that provide another level of protection for wafers. We believe that we are a market leader in wafer handling products. We offer a wide variety of products that hold and position wafers as they travel between each piece of equipment used in the automated manufacturing process. These specialized carriers provide precise wafer positioning, wafer protection and highly reliable and predictable cassette interfaces in automated fabs. Semiconductor manufacturers rely on our products to improve yields by protecting wafers from abrasion, degradation and contamination during the manufacturing process. We provide standard and customized products that meet the full spectrum of industry standards and customers’ wafer handling needs including FOUPs, wafer transport and process carriers, SMIF pods and work-in-process boxes. To meet our customers’ varying wafer processing and transport needs, we offer wafer carriers in a variety of materials and in sizes ranging from 100 mm through 300 mm. We believe we are the only global provider currently offering outsourcing programs for wafer and device transportation and protection for both wafer manufacturing and wafer handling products. Our Wafercare ®, and DeviceCare SM services include product cleaning, certified re-use services for shipping products, on-site and off-site product maintenance and optimization, and end-of-life recycling for our wafer, device and disk-handling products. Re-use services can be customized depending on the customers needs to provide product cleaning, logistics, recovery, certification and supply solutions for our products. FINISHED ELECTRONIC COMPONENT PRODUCTS. Rapidly changing packaging strategies for semiconductor applications are creating new materials management challenges for back-end manufacturers. We offer chip and matrix trays as well as carriers for bare die handling and integrated circuits. Our materials management products are compatible with industry standards and available in a wide range of sizes with various feature sets. Our standard trays offer dimensional stability and permanent electrostatic discharge protection. Our trays also offer a number of features including custom designs to minimize die movement and contact; shelves and pedestals to minimize direct die contact, special pocket features to handle various surface finishes to eliminate die sticking; and other features for automated or manual die placement and removal. In addition, we support our product line with a full range of accessories to address specific needs such as static control, cleaning, chip washing and other related materials management requirements. To better address this market, we have established ictray.com, a website which allows new and existing customers to select from our full range of standard and custom integrated circuit trays. Like the semiconductor industry, the data storage market continues to face new challenges and deploy new technologies at an accelerating rate. We provide materials management products and solutions to manage two critical sectors of this industry: magnetic disks and the read/write heads used to read and write today’s higher density disks. Because both of these hard disk drive components are instrumental in the transition to more powerful storage solutions, we offer products that carefully protect and maintain the integrity of these components during their processing, storage and shipment. Our product offerings for magnetic hard disk drives include process carriers, boxes, packages, tools and shippers for aluminum and other disk substrates. Our optical hard disk drive products include stamper cases, process carriers, boxes and glass master carriers. Our read/write head products include transport trays, carriers, handles, boxes, individual disk substrate packages and accessories. 7 Liquid Micro-contamination Control Products Liquid processing occurs during multiple manufacturing steps including photolithography, deposition, planarization and surface etching and cleaning. The fluids that are used include various mixtures of acids, bases, solvents, slurries and photochemicals, which in turn are used over a broad range of operating conditions, including temperatures from 5 degrees Celsius up to 180 degrees Celsius. The design and performance of our liquid filtration and purification products are critical to the semiconductor manufacturing process because they directly affect the cost of ownership and manufacturing yield. Specially designed proprietary filters remove sub-micron sized particles and bubbles from the different fluid streams that are used in the manufacturing process. Some of our filters are constructed with ultra-high molecular weight polyethylene flat sheet membranes that offer improved bubble clearance and gel removal, either of which can cause defects in the wafers if not removed. Our low hold-up volume disposable filters, with flat sheet membranes, use our Connectology ™ technology to allow filter changes in less than a minute, significantly faster than conventional filters, to reduce the amount of expensive chemicals lost each time a filter is changed and to minimize operator exposure to hazardous solvents and vapors during changeout. We also offer a line of consumable PVA roller brush products to clean the wafer following the chemical mechanical planarization process. Our unique Planacore ™ PVA roller brush is molded on the core to allow easy installation that reduces tool downtime and a dimensionally stable product that provides consistent wafer to wafer cleaning performance. Liquid Systems CHEMICAL DELIVERY PRODUCTS. Chemicals spend most of their time in contact with fluid storage and management distribution systems, so it is critical for fluid storage and handling components to resist these chemicals and avoid contributing contaminants to the fluid stream. We offer chemical delivery products that allow the consistent and safe delivery of sophisticated chemicals from the chemical manufacturer to the point-of-use in the semiconductor fab. Most of these products are made from perfluoroalkoxy or PFA, a fluoropolymer resin widely used in the industry because of its high purity and inertness to chemicals. The innovative design and reliable performance of our products and systems under the most stringent of process conditions has made us a recognized leader in high purity fluid transfer products and systems. Both semiconductor manufacturers and semiconductor OEMs use our chemical delivery products and systems. Our comprehensive product line provides our customers with a single source provider for their chemical storage and management needs throughout the manufacturing process. Our chemical delivery products include valves, fittings, tubing, pipe, chemical containers and custom fabricated products for high purity chemical applications. LIQUID DELIVERY AND CONTROL SYSTEMS. Our proprietary photochemical filtration and dispense systems integrate our patented two-stage, filter device and valve control technologies. We believe that we offer the microelectronics industry the only dispense systems with integrated filtration capability and that our proprietary patented two-stage technology has a significant advantage over conventional single-stage technology. Our two-stage technology permits the filtering and dispense functions to operate independently so that filtering and dispensing of photochemicals can occur at different rates, reducing the differential pressure across the filter, conserving expensive photochemicals and resulting in reduced defects in wafers. As described above, we offer a line of proprietary filters specifically designed to efficiently connect with these systems. Our patented digital valve control technology improves chemical uniformity on wafers and improves ease of optimized system operation. In addition, our integrated high precision liquid dispense systems enable uniform application of photoresists for the spin-coating process where uniformity is measured in units of Angstroms, a tiny fraction of the thickness of a human hair. We offer a wide variety of measurement and control products for high purity and corrosive applications. For electronic measurement and control of liquids, we provide a complete line of pressure and flow measurement and control products as well as all-plastic capacitance sensors for leak detection, valve position, chemical level and other measurements. We also offer a complete line of sight tube-style flowmeters and mechanical gauge pressure measurement products. 8 Gas Micro-Contamination Products Our Wafergard®, ChamberGard™ and Waferpure® particle and molecular filtration products purify the gas entering the process chamber in order to eliminate system and wafer problems due to particulate, atmospheric and chemical contaminants. These filters are able to retain all particles 0.003 microns and larger. Our metal filters, such as stainless steel and nickel filters, reduce outgassing and improve corrosion resistance. Our Waferpure® and Aeronex Gatekeeper® purifiers chemically react with and absorb volatile contaminants, such as oxygen and water, to prevent contamination and our ChamberGard™ vent diffusers reduce particle contamination and processing cycle times. We offer a wide variety of gas purification products to meet the stringent requirements of semiconductor processing. Our Aeronex Gas Purification Systems contain dual resin beds providing a continuous supply of purified gas without process interruption. These gas purification systems are capable of handling higher flow rates and longer duty cycles than cartridge purifiers. Our Extraction products include filter housings and hybrid media chemical air filters which purify air entering exposure tool and process tool enclosures and remove airborne molecular contaminants. In addition to the above four product categories, we have undertaken an initiative to transfer our advanced polymer knowledge into the fuel cell market, where the properties of highly engineered polymers can be used in various products and manufacturing processes. Worldwide Applications Development and Field Support Capabilities We provide strong technical support to our customers through local service groups and engineers consisting of field applications engineers, technical service groups, applications development groups and training capabilities. Our field applications engineers, located in the United States and in approximately ten other countries, work directly with our customers on product qualification and process improvement in their facilities. In addition, in response to customer needs for local technical service and fast turn-around time, we maintain regional applications laboratories. Our applications laboratories maintain process equipment that simulate customers’ applications and industry test standards and provide product evaluation, technical support and complaint resolution for our customers. OUR CUSTOMERS AND MARKETS Our major customer groups include integrated circuit device manufacturers, original equipment manufacturers that provide equipment to integrated circuit device manufacturers, gas and chemical manufacturing companies and manufacturers of high precision electronics. Our most significant customers based on sales in fiscal 2006 include industry leaders, such as AMD, Dainippon Screen Manufacturing Co., Freescale Semiconductor, IBM, Komag, Inc., Samsung America Inc., Seagate Technology, Siltronic AG, SUMCO Oregon Corp., Taiwan Semiconductor Manufacturing Co. Ltd., and UMC Group. We also sell our products to flat panel display original equipment manufacturers, materials suppliers and end-users. The major manufacturers for flat panel displays and flat panel display equipment are concentrated in Japan, Korea and other parts of Asia. In calendar years 2006, 2005 and 2004, net sales to our top ten customers accounted for approximately 28%, 32% and 33%, respectively, of our net sales. During those same periods no single customer accounted for more than 10% of our net sales and international net sales represented approximately 71%, 71% and 71%, respectively, of our net sales. Over 3,000 customers purchased products from us during 2006. We may enter into supply agreements with our customers to govern the conduct of business between us and our customers, including the manufacture of our products. These agreements generally have a term of one to three years but these agreements do not contain any long-term purchase commitments. Instead, we work closely with our customers to develop non-binding forecasts of the future volume of orders. However, customers may cancel their orders, change production quantities from forecasted volumes or delay production for a number of reasons beyond our control. 9 SALES AND MARKETING We sell our products worldwide primarily through our own direct sales force located in offices in all major semiconductor markets, as well as through independent distributors elsewhere. As of December 31, 2006, our sales and marketing force consisted of approximately 450 employees worldwide. Our direct sales force is supplemented by independent sales representatives and agents. Our marketing efforts focus on our “push/pull” marketing strategy in order to maximize our selling opportunities. We work with original equipment manufacturers to persuade them to design tools that require our products and we create end user “pull” demand by persuading semiconductor manufacturers to specify our products. Our industry relationships have provided us with the opportunity for significant collaboration with our customers at the product design stage that has facilitated our ability to introduce new products and applications that meet our customers’ needs. In addition, we are constantly identifying for our customers the variety of analytical, purification and process control challenges which may be addressed by our products. Further, we adapt our products and technologies to resolve process control issues identified by our customers. Our sales representatives provide our customers with worldwide support and information about our products. We believe that our technical support services are important to our marketing efforts. These services include assisting in defining a customer’s needs, evaluating alternative products, designing a specific system to perform the desired separation, training users and assisting customers in compliance with relevant government regulations. In addition, we maintain a network of service centers located in the United States and in key international markets to support our products. COMPETITION The market for our products is highly competitive. While price is an important factor, we compete primarily on the basis of the following factors: • • • • • historical customer relationships; technical expertise; product quality and performance; total cost of ownership; customer service and support; • • • • breadth of product line; breadth of geographic presence; advanced manufacturing capabilities; and after-sales service. We believe that we compete favorably with respect to all of the factors listed above, but we cannot assure you that we will continue to do so. We believe that our key competitive strengths include our broad product line, the low total cost of ownership of our products, our ability to provide our customers with quick order fulfillment and our technical expertise. However, our competitive position varies depending on the market segment and specific product areas within these segments. While we have longstanding relationships with a number of semiconductor and other electronic device manufacturers, we also face significant competition from companies that have longstanding relationships with other semiconductor and electronic device manufacturers and, as a result, have been able to have their products specified by those customers for use in manufacturers’ fabrication facilities. In the markets for our consumable products, we believe that our differentiated membrane and materials integrity management technologies, strong supply chain capabilities, which allow us to provide our customers with quick order fulfillment, and technical expertise, which enables us to develop membranes to meet specific customer needs and assist our customers in improving the functionality of our membranes for particular applications, allow us to compete favorably. In these markets our competitors compete against us on the basis of price, as well as alternative membrane technology having different functionality, manufacturing capabilities and breadth of geographic presence. 10 The market for our products is highly fragmented, and we compete with a number of different companies. Our microenvironment product lines face competition largely on a product-by-product basis. We have historically faced competition from companies such as Miraial (formerly Kakizaki), Dainichi and Shin-Etsu Polymer. These companies compete with us primarily in 200 mm and 300 mm applications. Our liquid systems products also face worldwide competition from companies such as Saint-Gobain, Parker, Gemu and Iwaki Co., Ltd. In finished electronic components products, we compete with companies such as ITW/Camtex, Peak International and 3M and with regional suppliers. Our liquid micro-contamination control products compete with product offerings from a wide range of companies including both large companies such as Pall Corporation as well as small Asian filter manufacturers. In gas micro-contamination products we compete with companies such as SAES Puregas and Mott Metallurgical Corporation. Some of our competitors are larger and have greater resources than we do. In some cases, our competitors are smaller than us, but well-established in specific product niches. However, we believe that none of our competitors competes with us across all of our product offerings and that, within the markets that we serve, we offer a broader line of products, make use of a wider range of process control technologies and address a broader range of applications than any single competitor. RESEARCH AND DEVELOPMENT Our aggregate research and development expenses in calendar years 2006, 2005 and 2004 were $ 38.8 million, $36.3 million and $38.5 million, respectively. As of February 1, 2007, we had approximately 230 employees in engineering, research and development. We have followed a practice of supplementing our internal research and development efforts by licensing technology from unaffiliated third parties and/or acquiring distribution rights with respect thereto when we believe it is in our long-term interests to do so. To meet the global needs of our customers, we have research and development capabilities in Chaska, MN and Billerica, MA, as well as in Japan and Malaysia. Our research and development efforts are directed toward developing and improving our technology platforms for semiconductor and advanced processing applications and identifying and developing products for new applications for which fluid management plays a critical role. We use sophisticated methodologies to research, develop and characterize our materials and products. Our materials technology lab is equipped to analyze the physical, rheological, thermal, chemical and compositional nature of the polymers we use. Our materials lab includes standard and advanced polymer analysis equipment such as inductively coupled plasma mass spectrometry (ICP/MS), inductively coupled plasma atomic emission spectrometry (ICP/AES), fourier transform infrared spectroscopy (FTIR) and automated thermal desorption gas chromatography/mass spectrometry (ATD-GC/MS). This advanced analysis equipment allows us to detect contaminants in materials that could harm the semiconductor manufacturing process to levels as low as parts per billion, and in many cases parts per trillion. Our capabilities to test and characterize our materials and products are focused on continuously reducing risks and threats to the integrity of the critical materials that our customers use in their manufacturing processes. We expect that technology and product research and development will continue to represent an important element in our ability to develop and characterize our materials and products. Key elements of our research and development expenditures over the past three years have included the development of new product platforms to meet the manufacturing needs for 90 and 65 nanometer semiconductor devices. Driven by the proliferation of new materials and chemicals in the manufacturing processes and increased needs for tighter process control for 300mm wafers, investments were made for new contamination control products in the area of copper interconnects, deep ultra-violet (DUV) photolithography; and chemical and gas management technologies for advanced wafer cleans, deposition and etch equipment. Additional investments were made in the area of advanced process control, monitoring and diagnostics capabilities for future generations of semiconductor manufacturing processes. Our employees also work closely with our customers’ development personnel. These relationships help us identify and define future technical needs on which to focus our research and development efforts. In addition, we participate in Semiconductor Equipment and Materials International (SEMI), a consortium of semiconductor equipment suppliers. We also support research at academic and other institutions targeted at advances in materials science and semiconductor process development. 11 MANUFACTURING Our customers rely on our products to assure the integrity of the critical materials used in their manufacturing processes by providing dimensional precision and stability, cleanliness and consistent performance. Our ability to meet our customers’ expectations, combined with our substantial investments in worldwide manufacturing capacity, position us to respond to the increasing materials integrity management demands of the microelectronics industry and other industries that require similar levels of materials integrity. To meet our customer needs worldwide, we have established an extensive global manufacturing network with manufacturing facilities in the United States, Japan and Malaysia. Because we work in an industry where contamination control is paramount, we maintain Class 100 to Class 10,000 cleanrooms for manufacturing and assembly. We believe that our worldwide manufacturing operations and our advanced manufacturing capabilities are important competitive advantages. Our advanced manufacturing capabilities include: • • • • • Injection Molding. Our manufacturing expertise is based on our long experience with injection molding. Using molds produced from computer-aided processes, our manufacturing technicians utilize specialized injection molding equipment and operate within specific protocols and procedures established to consistently produce precision products. Extrusion. Extrusion is accomplished through the use of heat and force from a screw to melt solid polymer pellets in a cylinder and then forcing the resulting melt through a die to produce tubing and pipe. We have established contamination free on-line laser marking and measurement techniques to properly identify products during the extrusion process and ensure consistency in overall dimension and wall thickness. In addition, we use extrusion technology to extrude a polymer mix into flat sheet and hollow fiber membranes. Blow Molding. Blow molding consists of the use of heat and force from a screw to melt solid polymer pellets in a cylinder and then forcing the melt through a die to create a hollow tube. The molten tube is clamped in a mold and expanded with pressurized gas until it takes the shape of the mold. We utilize advanced three-layer processing to manufacture 55 gallon drums, leading to cost savings while simultaneously assuring durability, strength and purity. Rotational Molding. Rotational molding is accomplished by the placing of a solid polymer powder in a mold, placing the mold in an oven and rotating the mold on two axes so that the melting polymer coats the entire surface of the mold. This forms a part in the shape of the mold upon cooling. We use rotational molding in manufacturing containers up to 5,000 liters. Compression Molding. In compression molding, thermoset polymers are processed. Today, we use this manufacturing process primarily for manufacturing bipolar plates and end-plates for the fuel cell market. We use the same expertise as in injection molding to assure a consistently produced precision product. • Membrane Casting. We cast membrane by extruding a polymer into flat sheet or hollow fiber format that is passed through a chamber with controlled atmospheric conditions to control the development of voids or pores in the membrane. Once cast, the membrane is subjected to solvent extraction and annealing steps. The various properties of the membranes that we offer are developed during subsequent process steps. • Cartridge Manufacturing. We fabricate the membrane we manufacture as well as membranes manufactured by others into finished filtration cartridges in a variety of configurations. The fabrication process involves membrane processing into pleated and other configurations around a central core and enclosing it in framework of end caps and protective screening for use in fabricated cartridge housings. We also manufacture filter cartridges that are integrated into their own housings and incorporate our patented Connectology™ quick connect technology. • Machining. Machining consists of the use of computer-controlled equipment to create shapes, such as valve bodies, out of solid polymer blocks or rods. Our computerized machining capabilities enable speed and repeatability in volume manufacturing of our machined products, particularly products utilized in chemical delivery applications. 12 • • Assembly. We have established protocols, flow charts, work instructions and quality assurance procedures to assure proper assembly of component parts. The extensive use of robotics throughout our facilities reduces labor costs, diminishes the possibility of contamination and assures process consistency. Tool Making. We employ approximately 60 tool development and tool making related staff at locations in the United States and Malaysia. Our toolmakers produce the majority of the tools we use throughout the world. We have made significant investments in systems and equipment to create innovative products and tool designs. Our computer-aided design (CAD) equipment allows us to develop three-dimensional electronic models of desired customer products to guide design and tool-making activities. Our CAD equipment also aids in the rapid prototyping of products. We also use computer-automated engineering in the context of mold flow analysis. Beginning with a three- dimensional CAD model, mold flow analysis is used to visualize and simulate how our molds will fill. The mold flow analysis techniques cut the time needed to bring a new product to market because of the reduced need for sampling and development. Also, our CAD equipment can create a virtual part with specific geometries, which drives subsequent tool design, tool manufacturing, mold flow analysis and performance simulation. In conjunction with our three-dimensional product designs, we use finite element analysis software to simulate the application of a variety of forces or pressures to observe what will happen during product use. This analysis helps us anticipate forces that affect our products under various conditions. The program also assists our product designers by measuring anticipated stresses against known material strengths and establishing proper margins of safety. PATENTS AND OTHER INTELLECTUAL PROPERTY RIGHTS We rely on a combination of patent, copyright, trademark and trade secret laws and license agreements to establish and protect our proprietary rights. As of February 1, 2007 our patent portfolio included 323 current U.S. patents, 627 current foreign patents, including counterparts to U.S. filings, 141 pending U.S. patent applications, 62 pending filings under the Patent Cooperation Treaty not yet nationalized and 824 pending foreign patent applications. While we believe that patents may be important for aspects of our business, we believe that our success also depends more upon close customer contact, innovation, technological expertise, responsiveness and worldwide distribution. Additionally, while our patented technology may delay or deter a competitor in offering a competing product, we do not believe that our patent portfolio functions as a barrier to entry for any of our competitors. In addition, while we license and will continue to license technology used in the manufacture and distribution of products from third parties, except as described below, these licenses are not currently related to any of our core product technology. In connection with the separation of Mykrolis from Millipore Corporation, Mykrolis was granted licenses to certain Millipore technology. Our use of Millipore’s technology is governed by the agreements governing the separation of Mykrolis from Millipore which prohibit our use of Millipore’s technology in fields of use outside of the microelectronics industry. In general, where, at the time of the separation, technology was used both by Millipore in the manufacture of its products and by us in the manufacture of our products, Millipore retained ownership of the technology and granted us a license to use the technology limited to fields of use in the microelectronics industry. These restrictions could limit our ability to expand our business into markets outside the microelectronics industry, which could limit our growth. We require each of our employees, including our executive officers, to enter into standard agreements pursuant to which the employee agrees to keep confidential all of our proprietary information and to assign to us all inventions made while employed by us. The patent position of any manufacturer, including us, is subject to uncertainties and may involve complex legal and factual issues. Litigation is currently necessary and will likely be necessary in the future to enforce our 13 patents and other intellectual property rights or to defend ourselves against claims of infringement or invalidity. The steps that we have taken in seeking patents and other intellectual property protections may prove inadequate to deter misappropriation of our technology and information. In addition, our competitors may independently develop technologies that are substantially equivalent or superior to our technology. GOVERNMENTAL REGULATION Our operations are subject to federal, state and local regulatory requirements relating to environmental, waste management and health and safety matters, including measures relating to the release, use, storage, treatment, transportation, discharge, disposal and remediation of contaminants, hazardous substances and wastes, as well as practices and procedures applicable to the construction and operation of our plants. There can be no assurance that we will not incur material costs and liabilities or that our past or future operations will not result in exposure to injury or claims of injury by employees or the public. Although some risk of costs and liabilities related to these matters is inherent in our business, as with many similar businesses, we believe that our business is operated in substantial compliance with applicable regulations. However, new, modified or more stringent requirements or enforcement policies could be adopted, which could adversely affect us. While we expect that capital expenditures will be necessary to assure that any new manufacturing facility is in compliance with environmental and health and safety laws, we do not expect these expenditures to be material. Otherwise, we are not presently aware of any facts or circumstances that would cause us to incur significant liabilities in the future related to environmental, health and safety law compliance. EMPLOYEES As of February 1, 2007, we had approximately 3,000 full-time employees, including approximately 230 in engineering, research and development and approximately 450 in sales and marketing as well as approximately 325 temporary employees. Given the variability of business cycles in the semiconductor industry and the quick response time required by our customers, it is critical that we be able to quickly adjust the size of our production staff to maximize efficiency. Therefore, we use skilled temporary labor as required. None of our employees are represented by a labor union or covered by a collective bargaining agreement other than statutorily mandated programs in European countries. INFORMATION ABOUT OUR OPERATING SEGMENT The Company operates in one reportable business segment that develops, manufactures and sells consumables and capital equipment products to semiconductor manufacturing companies and other companies using similar manufacturing processes, as well as OEM suppliers to those companies. In calendar years 2006, 2005 and 2004 approximately 71%, 71% and 71%, respectively, of our net sales were made to customers outside North America. Industry and geographic segment information is discussed in Note 20 to the Entegris, Inc. Consolidated Financial Statements (the “Financial Statements”) included in response to Item 8 below, which Note is hereby incorporated herein by reference. OTHER INFORMATION On July 27, 2005, our Board of Directors adopted a shareholder rights plan (the “Rights Plan”) pursuant to which Entegris declared a dividend on August 8, 2005 to its shareholders of record on that date of one preferred share purchase right (a “Right”) for each share of Entegris common stock owned on August 8, 2005. Each Right entitles the holder to purchase one-hundredth of a share of a series of preferred stock at an exercise price of $50, subject to adjustment as provided in the Rights Plan. The Rights Plan is designed to protect Entegris’ shareholders from attempts by others to acquire Entegris on terms or by using tactics that could deny all shareholders the opportunity to realize the full value of their investment. The Rights are attached to the shares of our common stock until certain triggering events specified in the Rights Agreement occur, including, unless 14 approved by our board of directors, an acquisition by a person or group of specified levels of beneficial ownership of our common stock or a tender offer for our common stock. Upon the occurrence of any of these triggering events, the Rights authorize the holders to purchase shares of our common stock at the then-current exercise price having a value equal to twice the exercise price. The Rights are redeemable by us for $0.01 and will expire on August 8, 2015. One of the events which will trigger the Rights is the acquisition, or commencement of a tender offer, by a person (an Acquiring Person, as defined in the shareholder rights plan), other than Entegris or any of our subsidiaries or employee benefit plans, of 15% or more of the outstanding shares of our common stock. An Acquiring Person may not exercise a Right. Entegris’ products are made from a wide variety of raw materials which are generally available in quantity from alternate sources of supply. However, certain materials included in the Company’s products are obtained from a single source or a limited group of suppliers. Although the Company seeks to reduce dependence on those sole and limited source suppliers, the partial or complete loss of these sources could have at least a temporary adverse effect on the Company’s results of operations. Furthermore, a significant increase in the price of one or more of these components could adversely affect the Company’s results of operations. OUR HISTORY Effective August 6, 2005 Entegris, Inc., a Minnesota corporation, and Mykrolis Corporation, a Delaware corporation, completed a strategic merger of equals transaction, pursuant to which they were each merged into the Company to carry on the combined businesses. Pursuant to this merger each stockholder of Entegris Minnesota received one share of Entegris for each Entegris Minnesota share held and each Mykrolis stockholder received 1.39 shares of Entegris for each Mykrolis share held. Our board of directors is comprised of five directors from Entegris Minnesota and five directors from Mykrolis. Our management team is drawn from both Mykrolis and Entegris Minnesota. Our executive offices are located at 3500 Lyman Boulevard, Chaska, Minnesota 55318, and our telephone number is (952) 556-3131. Unless the context otherwise requires, the terms “Entegris”, “we”, “our”, or the “Company” mean Entegris, Inc., a Delaware corporation, and its subsidiaries; the term “Mykrolis” means Mykrolis Corporation and its subsidiaries when referring to periods prior to August 6, 2005; “Entegris Minnesota” means Entegris, Inc., a Minnesota corporation and its subsidiaries other than Entegris when referring to periods prior to August 6, 2005; and the term “Merger” refers to the transactions effected on August 6, 2005 in which Entegris Minnesota merged into Entegris, followed by the merger of Mykrolis into Entegris. We were incorporated in Delaware in June 2005 under the name Eagle DE, Inc. as a wholly owned subsidiary of Entegris Minnesota. Effective August 6, 2005 Entegris Minnesota merged into us in a reincorporation merger of which we were the surviving corporation. Immediately following that merger, Mykrolis merged into us and our name was changed to Entegris, Inc. Our stock is traded on the NASDAQ under the symbol “ENTG”. Entegris Minnesota was incorporated in June 1999 to effect the business combination of Fluoroware, Inc., which began operating in 1966, and EMPAK, Inc., which began operating in 1980. On July 10, 2000 Entegris Minnesota completed an initial public offering of approximately 19% of the total shares of the Company’s common stock outstanding. Mykrolis was organized as a Delaware corporation on October 16, 2000 under the name Millipore MicroElectronics, Inc. in connection with the spin-off by Millipore Corporation of its microelectronics business unit. On March 31, 2001, Millipore effected the separation of the Mykrolis business from Millipore’s business by transferring to Mykrolis substantially all of the assets and liabilities associated with its microelectronics business. On August 9, 2001 Mykrolis completed an initial public offering of approximately 18% of the total shares of the Company’s common stock outstanding. On February 27, 2002, Millipore completed the spin-off of Mykrolis by distributing to its stockholders the 82% of the Mykrolis common stock that it held following the Mykrolis initial public offering. 15 EXECUTIVE OFFICERS The following is a list, as of December 31, 2006, of our Executive Officers.

Risks Relating to our Business and Industry The semiconductor industry has historically been highly cyclical, and industry downturns reduce revenue and profits. Our business depends on the purchasing patterns of semiconductor manufacturers, which, in turn, depend on the current and anticipated demand for semiconductors and products utilizing semiconductors. The semiconductor industry has historically been highly cyclical with periodic downturns, which often have resulted in decreased expenditures by semiconductor manufacturers. While over the past twelve quarters this cyclicality has moderated somewhat, there can be no assurance that the semiconductor industry will not return to the high cyclicality of the past. Even this somewhat moderated cyclicality could cause our operating results to decline significantly from one period to the next. Furthermore, even in periods of reduced demand, we must continue to maintain a satisfactory level of research and development expenditures and continue to invest in our infrastructure. At the same time, we have to manage our operations to be able to respond to significant increases in demand. In addition, because we typically do not have significant backlog, changes in order patterns have a more immediate impact on our revenues. We expect the semiconductor industry to continue to be cyclical. Any future downturns will reduce revenue and possibly increase pricing pressure, affecting both gross margin and net income. Such fluctuations in our results could cause our share price to decline substantially. We believe that period-to-period comparisons of our results of operations may not be meaningful, and you should not rely upon them as indicators of our future performance. The semiconductor industry is subject to rapid demand shifts which are difficult to predict. As a result, our inability to meet demand in response to these rapid shifts may cause a reduction in our market share. Our ability to increase sales of our products, particularly our capital equipment products, depends in part upon our ability to ramp up the use of our manufacturing capacity for such products in a timely manner and to mobilize our supply chain. In order to meet the demands of our customers, we may be required to ramp up our manufacturing capacity in as little as a few months. If we are unable to expand our manufacturing capacity on a timely basis or manage such expansion effectively, our customers could seek such products from other suppliers, and our market share could be reduced. Because demand shifts in the semiconductor industry are rapid and difficult to foresee, we may not be able to increase capacity quickly enough to respond to such an increase in demand. Our annual and quarterly operating results are subject to fluctuations as a result of rapid demand shifts and our insignificant level of backlog and if we fail to meet the expectations of securities analysts or investors, the market price of our securities may decrease significantly. Our sales and profitability can vary significantly from quarter to quarter and year to year. Because our expense levels are relatively fixed in the short-term, an unanticipated decline in revenue in a particular quarter could disproportionately affect our net income in that quarter. In addition, we make a substantial portion of our shipments shortly after we receive the order, and therefore we operate with a relatively modest level of backlog. As a consequence of the just-in-time nature of shipments and the modest level of backlog, our results of operations may decline quickly and significantly in response to changes in order patterns or rapid decreases in demand for our products. We anticipate that fluctuations in operating results will continue in the future. Such fluctuations in our results could cause us to fail to meet the expectations of securities analysts or investors, which could cause the market price of our securities to decline substantially. We believe that period-to-period comparisons of our results of operations may not be meaningful, and you should not rely upon them as indicators of our future performance. 18 We may not be able to accurately forecast demand for our products. As noted above, we typically operate our business on a just-in-time shipment basis with a modest level of backlog and we order supplies and plan production based on internal forecasts of demand. Due to these factors, we have, in the past, and may again in the future, fail to accurately forecast demand for our products, in terms of both volume and specific products for which there will be demand. This has led to, and may in the future lead to, delays in product shipments, disappointment of customer expectations, or, alternatively, an increased risk of excess inventory and of inventory obsolescence. If we fail to accurately forecast demand for our products, our business, financial condition and operating results could be materially and adversely affected. Semiconductor industry up-cycles may not reach historic levels but instead may reflect a lower rate of long-term growth, similar to the electronics industry. Notwithstanding the severe and prolonged downturn in the semiconductor industry and the related reduction in manufacturing operations during the period 2001 to 2003, there may still be excess manufacturing capacity. In addition, there is no new high opportunity application to drive growth in the semiconductor industry, as was the case in 1998 with telecommunications and internet applications. Accordingly, some analysts have predicted that the semiconductor industry may experience lower growth rates during a recovery cycle than has historically been the case and that its longer-term performance may reflect this lower growth rate, which would be similar to the growth rate of the electronics industry. If we are unable to maintain our technological expertise in design and manufacturing processes, we will not be able to successfully compete. The microelectronics industry is subject to rapid technological change, changing customer requirements and frequent new product introductions. Because of this, the life cycle of our products is difficult to determine. We believe that our future success will depend upon our ability to develop and provide products that meet the changing needs of our customers, including the transition from the use of 200 millimeter wafers to 300 millimeter wafers, the shrinking of integrated circuit line-widths and the use of new classes of materials, such as copper, titanium nitride and organic and inorganic dielectric materials, which are materials that have either a low or high resistance to the flow of electricity. This requires that we successfully anticipate and respond to technological changes in manufacturing processes in a cost-effective and timely manner. Any inability to develop the technical specifications for any of our new products or enhancements to our existing products or to manufacture and ship these products or enhancements in volume in a timely manner could harm our business prospects and significantly reduce our sales. In addition, if new products have reliability or quality problems, we may experience reduced orders, higher manufacturing costs, delays in acceptance and payment, additional service and warranty expense and damage to our reputation. Because our sales are concentrated on a small number of key customers, our revenue and profitability may materially decline if one or more of our key customers do not continue to purchase our existing and new products in significant quantities. We depend and expect to continue to depend on a limited number of customers for a large portion of our business, and changes in several customers’ orders could have had a significant impact on our operating results. If any one of our key customers decides to purchase significantly less from us or to terminate its relationship with us, our revenue and profitability may decline significantly. We could also lose our key customers or significant sales to our key customers because of factors beyond our control, such as a significant disruption in our customers’ businesses generally or in a specific product line. These customers may stop incorporating our products into their products with limited notice to us and suffer little or no penalty for doing so. In addition, if any of our customers merge, we may experience lower overall sales from the merged companies. Because one of our strategies has been to develop long-term relationships with a few key customers in the product areas in which we focus and because we have a long product design and development cycle for most of our products and prospective customers typically require lengthy product qualification periods prior to placing volume orders, we may be unable to replace these customers quickly or at all. 19 Because we are subject to order and shipment uncertainties and many of our costs are fixed, any significant changes, cancellations or deferrals of orders or shipments could cause our revenue and profitability to decline or fluctuate. As is typical in the microelectronics industry, we do not usually obtain long-term purchase orders or commitments from our customers. Instead, we work closely with our customers to develop non-binding forecasts of the future volume of orders. Customers may cancel their orders, change production quantities from forecasted volumes or delay production for reasons beyond our control. Order cancellations or deferrals could cause us to hold inventory for longer than anticipated, which could reduce our profitability, restrict our ability to fund our operations and cause us to incur unanticipated reductions or delays in our revenue. Our customers often change their orders multiple times between initial order and delivery. Such changes usually relate to quantities or delivery dates, but sometimes relate to the specifications of the products we are supplying. If a customer does not timely pay for these products, we could incur significant charges against our income. In addition, our profitability may be affected by the generally fixed nature of our costs. Because a substantial portion of our costs is fixed, we may experience deterioration in gross margins when volumes decline. From time to time, we make capital investments in anticipation of future business opportunities. If we are unable to obtain the anticipated business, our revenue and profitability may decline. Competition from existing or new companies in the microelectronics industry could cause us to experience downward pressure on prices, fewer customer orders, reduced margins, the inability to take advantage of new business opportunities and the loss of market share. We operate in a highly competitive industry. We compete against many domestic and foreign companies that have substantially greater manufacturing, financial, research and development and marketing resources than we do. In addition, some of our competitors may have more developed relationships with our existing customers than we do, which may enable them to have their products specified for use more frequently by these customers. We also face competition from the manufacturing operations of our current and potential customers, who continually evaluate the benefits of internal manufacturing versus outsourcing. As more original equipment manufacturers dispose of their manufacturing operations and increase the outsourcing of their products to liquid and gas delivery system and other component companies, we may face increasing competitive pressures to grow our business in order to maintain our market share. If we are unable to maintain our competitive position, we could experience downward pressure on prices, fewer customer orders, reduced margins, the inability to take advantage of new business opportunities and a loss of market share. Competition in the semiconductor and data storage materials integrity management fields could intensify, which may limit our ability to maintain and increase our market share and raise prices. We face substantial competition from a number of companies, some of which have greater financial, marketing, manufacturing and technical resources. Larger providers of materials integrity management solutions and products could emerge, with potentially broader product lines. Larger competitors could spend more time and resources on research and development, which could give those competitors an advantage in meeting customer demand. We expect that existing and new competitors will improve the design of their existing products and will introduce new products with enhanced performance characteristics. The introduction of new products or more efficient production of existing products by our competitors could diminish our market share and increase pricing pressure on our products. Further, customers continue to demand lower prices, shorter delivery times and enhanced product capability. If we do not respond adequately to such pressures, we could lose customers or orders. If we are unable to compete successfully, we could experience pricing pressures, reduced gross margins and order cancellations. Lack of market acceptance of our 300 mm shipper products as well as our other products could harm our operating results. The growing trend toward the use of 300 mm wafers has contributed to the increasing complexity of the semiconductor manufacturing process. The greater diameter of these wafers requires higher tooling costs and 20 presents more complex handling, storage and transportation challenges. We have made substantial investments to complete a full line of 300 mm wafer shipping products, but there is no guarantee that our customers will adopt our 300 mm wafer shipping product lines as they convert existing 200 mm wafer fabrication facilities to 300 mm wafer fabrication, or build new 300 mm wafer fabrication facilities and sales of our shipping products for these applications would be minimal and we might not recover our development costs. Semiconductor and other electronic device manufacturers may direct semiconductor capital equipment manufacturers to use a specified supplier’s product in their equipment. Accordingly, our success depends in part on our ability to have semiconductor and other electronic device manufacturers specify that our products be used at their fabrication facilities. Some of our competitors may have more developed relationships with semiconductor and other electronic device manufacturers, which enable them to have their products specified for use in manufacturers’ fabrication facilities. We may acquire other businesses, form joint ventures or divest businesses that could negatively affect our profitability, increase our debt and dilute your ownership of our company. As part of our business strategy, we have, and we expect to continue to address gaps in our product offerings, diversify into complementary product markets or pursue additional technology and customers through acquisitions, joint ventures or other types of collaborations. We also expect to adjust our portfolio of businesses to meet our ongoing strategic objectives. As a result, we may enter markets in which we have no or limited prior experience and may encounter difficulties in divesting businesses that no longer meet our objectives. Competition for acquiring attractive businesses in our industry is substantial. In executing this part of our business strategy, we may experience difficulty in identifying suitable acquisition candidates or in completing selected transactions at appropriate valuations. Alternatively, we may be required to undertake multiple transactions at the same time in order to take advantage of acquisition opportunities that do arise; this could strain our ability to effectively execute and integrate these transactions. We intend to pay for these acquisitions with cash and/or our common stock which could impair our liquidity and dilute your ownership of our company. Further, we may not be able to successfully integrate any acquisitions that we do make into our existing business operations and we could assume unknown or contingent liabilities or experience negative effects on our reported results of operations from dilutive results from operations and/or from future potential impairment of acquired assets including goodwill related to future acquisitions. We may experience difficulties in operating in foreign countries or over significant geographical distances and in retaining key employees or customers of an acquired business, and our management’s attention could be diverted from other business issues. We may not identify or complete these transactions in a timely manner, on a cost effective basis or at all, and we may not realize the benefits of any acquisition or joint venture. Manufacturing Risks Our dependence on single and limited source suppliers could affect our ability to manufacture our products. We rely on single or limited source suppliers for some plastic polymers that are critical to the manufacturing of our products. At times, we have experienced a limited supply of certain polymers as well as the need to substitute polymers, resulting in delays, increased costs and the risks associated with qualifying new polymers with our customers. An industry-wide increase in demand for these polymers could affect the ability of our suppliers to provide sufficient quantities to us. If we are unable to obtain an adequate quantity of such supplies, our manufacturing operations may be interrupted. In addition, suppliers may discontinue production of polymers specified in certain of our products, requiring us in some instances to certify an alternative with our customers. If we are unable to obtain an adequate quantity of such supplies for any of the above reasons, our manufacturing operations may be affected. Obtaining alternative sources would likely result in increased costs and shipping delays, which could decrease profitability and damage our relationships with current and potential customers. 21 Prices for polymers can vary widely. In the current high oil price environment, some suppliers have added and may continue to add surcharges to the prices of the polymers we purchase. While, we have long-term arrangements with certain key suppliers of polymers that fixes our price for purchases up to specified quantities, if our polymer requirements exceed the quantities specified, we could be exposed to higher material costs. If the cost of polymers increases and we are unable to correspondingly increase the sales price of our products, our profit margins will decline. Our production processes are becoming increasingly complex, and our production could be disrupted if we are unable to avoid manufacturing difficulties. Our manufacturing processes are complex and require the use of expensive and technologically sophisticated equipment and materials. These processes are frequently modified to improve manufacturing yields and product quality. We have on occasion experienced manufacturing difficulties, such as temporary shortages of raw materials and occasional critical equipment breakdowns that have delayed deliveries to customers. A number of our product lines are manufactured at only one or two facilities, and any disruption could impact our sales until another facility could commence or expand production of such products. Our manufacturing operations are subject to numerous risks, including the introduction of impurities in the manufacturing process and other manufacturing difficulties that may not be well understood for an extended period of time that could lower manufacturing yields and make our products unmarketable; the costs and demands of managing and coordinating geographically diverse manufacturing facilities; and the disruption of production in one or more facilities as a result of a slowdown or shutdown in another facility. We could experience these or other manufacturing difficulties, which might result in a loss of customers and exposure to product liability claims. We may lose sales if we are unable to timely procure, repair or replace capital equipment necessary to manufacture many of our products. If our existing equipment fails, or we are unable to obtain new equipment quickly enough to satisfy any increased demand for our products, we may lose sales to competitors. In particular, we do not maintain duplicate tools for most of our important products. Fixing or replacing complex tools is time consuming, and we may not be able to replace a damaged tool in time to meet customer requirements. In addition, from time to time we may upgrade or add new manufacturing equipment which may require substantial lead times to build and qualify. Delays in building and qualifying new equipment could result in a disruption of our manufacturing processes and prevent us from meeting our customers’ requirements so that they would seek other suppliers. We incur significant cash outlays over long-term periods in order to research, develop, manufacture and market new products, which may never reach market or may have limited market acceptance. We make significant cash expenditures to research, develop and market new products. For example, in calendar year 2006 we incurred $38.8 million of engineering, research and development expense. Similarly, we incurred $36.3 million of research and development expense in calendar 2005 and $38.5 million in calendar 2004. The development period for a product can be as long as five years. Following development, it may take an additional two to three years for the sales of that product to reach a substantial level. We cannot be certain of the success of a new product. A product concept may never progress beyond the development stage or may only achieve limited acceptance in the marketplace. If this occurs, we do not receive a direct return on our expenditures and may not even realize any indirect benefits. Additionally, capacity expansion may be necessary in order to manufacture a new product. If sales levels do not increase to offset the additional fixed operating expenses associated with any such expansion, our revenue and profitability could decline and our prospects could be harmed. 22 We are subject to a variety of environmental laws which could cause us to incur significant expenses. In addition to other regulatory requirements affecting our business, we are subject to a variety of federal, state, local and foreign regulatory requirements relating to the use, disposal, clean-up of, and human exposure to, hazardous chemicals. We generate and handle materials that are considered hazardous waste under applicable law. If we fail to comply with any present or future regulations, we could be subject to future liabilities or the suspension of production. In addition, compliance with these or future laws could restrict our ability to expand our facilities or build new facilities or require us to acquire costly equipment, incur other significant expenses or modify our manufacturing processes. We are continually evaluating our manufacturing operations within our plants in order to achieve efficiencies and gross margin improvements. If we are unable to successfully manage transfers or realignments of our manufacturing operations, our ability to deliver product to our customers could be disrupted and our business, financial condition and results of operations could be adversely affected. In order to enhance the efficiency and cost effectiveness of our manufacturing operations we expect to move several product lines from one of our plants to another and to consolidate manufacturing operations in our plants. Our product lines involve technically complex manufacturing processes that require considerable expertise to operate. If we are unable to effect these transfers, realignments and consolidations in a systematic manner within established schedules or if we are unable to successfully operate relocated manufacturing processes in the destination plant, production may be disrupted and we may not be able to deliver these products to meet customer orders in a timely manner, which could harm our business. Loss of our key personnel could hurt our business because of their experience in the microelectronics industry and their technological expertise. Similarly, our inability to attract and retain new qualified personnel could inhibit our ability to operate and grow our business successfully. We depend on the services of our key senior executives and other technological experts because of their experience in the microelectronics industry and their technical expertise. The loss of the services of one or several of our key employees or an inability to attract, train and retain qualified and skilled employees, specifically research and development and engineering personnel, could result in the loss of customers or otherwise inhibit our ability to operate and grow our business successfully. In the past, during the extended downturn in the semiconductor industry our predecessor companies have had to impose salary reductions on senior employees and freeze or eliminate merit increases in an effort to maintain its financial position. Similarly, changes in accounting rules requiring fair value accounting for stock options will make it more expensive to provide our employees with equity incentives, which may require us to reduce the level of equity compensation. These actions may have an adverse effect on employee loyalty and may make it more difficult for us to attract and retain key personnel. If we are unable to protect our intellectual property rights, our business and prospects could be harmed. Our future success and competitive position depend in part upon our ability to obtain and maintain proprietary technology used in our principal product families. We rely, in part, on patent, trade secret and trademark law to protect that technology. We routinely enter into confidentiality agreements with our employees. However, there can be no assurance that these agreements will not be breached, that we will have adequate remedies for any breach or that our confidential and proprietary information and technology will not be independently developed by or become otherwise known to third parties. We have obtained a number of patents relating to our products and have filed applications for additional patents. We cannot assure you that any of our pending patent applications will be approved, that we will develop additional proprietary technology that is patentable, that any patents owned by or issued to us will provide us with competitive advantages or that these patents will not be challenged by third parties. Patent filings by third parties, whether made before or after the date of our filings, could render our intellectual property less valuable. Competitors may misappropriate our intellectual property, and disputes as to ownership of intellectual property may arise. In addition, if we do not obtain sufficient 23 international protection for our intellectual property, our competitiveness in international markets could be significantly impaired, which would limit our growth and future revenue. Furthermore, there can be no assurance that third parties will not design around our patents. Protection of our intellectual property rights has and may continue to result in costly litigation. We may from time to time be required to institute litigation in order to enforce our patents, copyrights or other intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. Such litigation could result in substantial costs and diversion of resources and could negatively affect our sales, profitability and prospects regardless of whether we are able to successfully enforce our rights. For example, as described in Item 3. “Legal Proceedings” below we are engaged in multiple patent litigations with Pall Corporation. We intend to prosecute and defend these cases vigorously and expect that these lawsuits will continue for extended periods of time and that we will incur substantial costs in pursuing them. In addition it may become necessary for us to initiate other costly patent litigation against this or other competitors in order to protect and/or perfect our intellectual property rights. If we infringe on the proprietary technology of others, our business and prospects could be harmed. Our commercial success will depend, in part, on our ability to avoid infringing or misappropriating any patents or other proprietary rights owned by third parties. If we are found to infringe or misappropriate a third party’s patent or other proprietary rights, we could be required to pay damages to such third party, alter our products or processes, obtain a license from the third party or cease activities utilizing such proprietary rights, including making or selling products utilizing such proprietary rights. If we are required to obtain a license from a third party, there can be no assurance that we will be able to do so on commercially favorable terms, if at all. International Risks We conduct a significant amount of our sales activity and manufacturing efforts outside the United States, which subjects us to additional business risks and may cause our profitability to decline due to increased costs. Sales to customers outside the United States accounted for approximately 71% of our net sales in each of calendar 2006, 2005 and 2004. We anticipate that international sales will continue to account for a majority of our net sales. In addition, a number of our key domestic customers derive a significant portion of their revenues from sales in international markets. We also manufacture a significant portion of our products outside the United States and are dependent on international suppliers for many of our parts. We intend to continue to pursue opportunities in both sales and manufacturing internationally. Our international operations are subject to a number of risks and potential costs that could adversely affect our revenue and profitability, including: • • • • • unexpected changes in regulatory requirements that could impose additional costs on our operations or limit our ability to operate our business; greater difficulty in collecting our accounts receivable and longer payment cycles than is typical in domestic operations; changes in labor conditions and difficulties in staffing and managing foreign operations; liability for foreign taxes assessed at rates higher than those applicable to our domestic operations; and political and economic instability. In the past, we have incurred costs or experienced disruptions due to the factors described above and expect to do so in the future. For example, our operations in Asia, and particularly Korea, Taiwan and Japan, have been negatively impacted in the past as a result of regional economic instability. In addition, Taiwan and Korea account for a growing portion of the world’s semiconductor manufacturing. There are currently strained relations 24 between China and Taiwan and there are continuing tensions between North Korea, and South Korea, Japan and the United States. Any adverse developments in those relations could significantly disrupt the worldwide production of semiconductors, which would lead to reduced sales of our products. Fluctuations in the value of the U.S. dollar in relation to other currencies may lead to lower net income or may cause us to raise prices, which could result in reduced net sales. Foreign currency exchange rate fluctuations could have an adverse effect on our net sales and results of operations. Unfavorable foreign currency fluctuations against the U.S. dollar could require us to increase prices to foreign customers, which could result in lower net sales by us to such customers. Alternatively, if we do not adjust the prices for our products in response to unfavorable foreign currency fluctuations, our profitability could decline. In addition, sales made by our foreign subsidiaries usually will be denominated in the currency of the country in which these products are sold, and the currency we receive in payment for such sales could be less valuable at the time of receipt versus the time of sale as a result of foreign currency exchange rate fluctuations. We may have exposure to income tax rate fluctuations as well as to additional tax liabilities, which would impact our financial position. As a corporation with operations in the United States as well as in numerous countries abroad, we are subject to income taxes in the United States as well as in various foreign jurisdictions. Our effective tax rate is subject to fluctuation as the income tax rates for each year will be determined by the following factors, among others: • The mix of profits and/or losses earned by us and our subsidiaries in various foreign tax jurisdictions with a broad range of income tax rates; • Our ability to utilize recorded deferred tax assets as well as tax holiday provisions available to us in certain jurisdictions; • Changes in contingencies related to taxes, interest or penalties resulting from tax audits; and • Changes in tax laws or the interpretation of such laws. Changes in the mix of these items and other items could cause our effective tax rate to fluctuate between periods, which could have a material adverse effect on our financial position. Significant judgment is required in determining our provision for income taxes and other tax liabilities. Although we believe that our tax estimates are reasonable, we cannot assure you that the final determination of tax audits or tax disputes will not be different from what is reflected in our historical income tax provisions and accruals. An increased concentration of wafer manufacturing in Japan could result in lower sales of our wafer shipper products. A large percentage of the world’s 300 mm wafer manufacturing currently takes place in Japan. Our market share in Japan is currently lower than in other regions we serve. If we are not able to successfully operate our manufacturing capability and increase market share in Japan, we might not be able to maintain our global market share in wafer shipper products, especially if 300 mm wafer manufacturing in Japan increases. Terrorist attacks, such as the attacks that occurred in New York and Washington, D.C. on September 11, 2001, and other acts of violence or war may affect the markets in which we operate and hurt our profitability. Terrorist attacks may negatively affect our operations and your investment. There can be no assurance that there will not be further terrorist attacks against the United States or United States businesses. These attacks or armed conflicts may directly impact our physical facilities or those of our suppliers or customers. Our primary facilities include headquarters, research and development and manufacturing facilities in the United States, sales, research and development and manufacturing facilities in Japan and Malaysia, and sales and service facilities in Europe 25 and Asia. Also these attacks have disrupted the global insurance and reinsurance industries with the result that we may not be able to obtain insurance at historical terms and levels for our facilities. Furthermore, these attacks may make travel and the transportation of our supplies and products more difficult and more expensive and may ultimately affect the sales of our products in the United States and overseas. As a result of terrorism the United States may enter into additional armed conflicts, which could have a further impact on our domestic and international sales, our supply chain, our production capacity and our ability to deliver products to our customers. The consequences of these armed conflicts and instability are unpredictable and we may not be able to foresee events that could have an adverse effect on our business and your investment. Risks Related to the Securities Markets and Ownership of our Securities Because of the past volatility of the stock price of Entegris Minnesota and Mykrolis, the price of our common stock in the future may likewise be volatile so that the ability to trade our common shares may be adversely affected and our ability to raise capital through future equity financing may be reduced. The stock prices of both of our predecessor companies have been volatile in the past and the price of our common stock may be volatile in the future. For example: in fiscal year 2006, the closing price of our stock on the NASDAQ National Market ranged from a low of $8.45 to a high $11.92. The trading price of our common shares is subject to wide fluctuations in response to various factors, some of which are beyond our control, including factors discussed elsewhere in this report and including the following: the failure to meet the published expectations of securities analysts; changes in financial estimates by securities analysts; press releases or announcements by, or changes in market values of, comparable companies; volatility in the markets for high technology stocks, general stock market price and volume fluctuations, which are particularly common among securities of high technology companies; stock market price and volume fluctuations attributable to inconsistent trading volume levels; additions or departures of key personnel; and involvement in or adverse results from litigation. These market fluctuations may cause the trading price of our common stock to decrease. Recently enacted changes in the securities laws and regulations are likely to increase our costs. The Sarbanes-Oxley Act of 2002 has required changes in some of our corporate governance, securities disclosure and compliance practices. In response to the requirements of that Act, the Securities and Exchange Commission and the NASDAQ have promulgated new rules and listing standards covering a variety of subjects. Compliance with these new rules and listing standards has increased our legal and financial and accounting costs, and we expect these increased costs to continue indefinitely. We also expect these developments to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be forced to accept reduced coverage or incur substantially higher costs to obtain coverage. Likewise, these developments may make it more difficult for us to attract and retain qualified members of our board of directors, particularly independent directors, or qualified executive officers. If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results. As a result, current and potential stockholders could lose confidence in our financial reporting, which would harm our business and the trading price of our stock. Effective internal controls are necessary for us to provide reliable financial reports. If we cannot provide reliable financial reports, our business and operating results could be harmed. We have in the past discovered, and may in the future discover, areas of our internal controls that need improvement. For example, during the fiscal 2005 year-end audit, a material weakness in internal control over financial reporting was identified; specifically we did not have effective policies and procedures, or personnel with sufficient knowledge of accounting for compensation related matters in purchase accounting transactions, to ensure that such transactions were accounted for in accordance with generally accepted accounting principles. This material weakness represented 26 more than a remote likelihood that a material misstatement of the Company’s annual or interim financial statements would not have been prevented or detected. The impact of this adjustment did not require the restatement of any of our financial statements. Remediation actions with respect to this material weakness have been completed. In 2006, management conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this evaluation, management concluded that the Company’s internal control over financial reporting was not effective due to the material weakness related to our accounting for income taxes. A material weakness in internal control over financial reporting is a significant deficiency, or combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. The Company plans to conduct remediation efforts throughout 2007 to address this material weakness. Any failure to implement and maintain the improvements in the controls over our financial reporting, or difficulties encountered in the implementation of these improvements in our controls, could cause us to fail to meet our reporting obligations. Any failure to improve our internal controls to address the identified material weakness could also cause investors to lose confidence in our reported financial information, which could have a negative impact on the trading price of our stock. There can be no assurance that we will not discover material weaknesses in our internal control over financial reporting in the future. Changes to financial accounting standards may affect our reported results of operations and could result in a decrease in the value of your shares. With the commencement of effectiveness of the requirement that employee stock option and employee stock purchase plan shares should be treated as a compensation expense using the fair value method, we will incur significant compensation charges and our results of operations could be adversely affected. Provisions in our charter documents, Delaware law and our shareholder rights plan may delay or prevent an acquisition of us, which could decrease the value of your shares. Our certificate of incorporation and By-Laws, Delaware law and our shareholder rights plan contain provisions that could make it harder for a third party to acquire us without the consent of our board of directors. These provisions include limitations on actions by our stockholders by written consent. In addition, our board of directors has the right to issue preferred stock without stockholder approval, which could be used to dilute the stock ownership of a potential hostile acquirer. Our shareholder rights plan will permit our stockholders to purchase shares of our common stock at a 50% discount upon the occurrence of specified events, including the acquisition by anyone of 15% or more of our common stock, unless such event is approved by our board of directors. Delaware law also imposes restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock. Although we believe these provisions provide for an opportunity to receive a higher bid by requiring potential acquirers to negotiate with our board of directors, these provisions apply even if the offer may be considered beneficial by stockholders. If a change of control or change in management is delayed or prevented, the market price of our common stock could suffer. Your percentage ownership in us may be diluted by future issuances of capital stock, which could reduce your influence over matters on which stockholders vote. Subject to applicable NASDAQ standards, our board of directors has the authority, without action or vote of our stockholders, to issue all or any part of our authorized but unissued shares. Issuances of common stock or the exercise of employee and director stock options would dilute your percentage ownership interest, which will have the effect of reducing your influence over matters on which our stockholders vote. In addition, we may issue substantial quantities of our common stock in order to effect acquisitions which will also dilute your ownership interest. If the issuances are made at prices that reflect a discount from the then current trading price of our common stock, your interest in the book value of our common stock might be diluted. 27 Item 1B.

We lease approximately 4,200 square feet of manufacturing space in Millipore’s facility located at 80 Ashby Road, Bedford, MA pursuant to an Amended and Restated Membrane Manufacturing and Supply Agreement that expires December 31, 2010. We also lease approximately 21,000 square feet of research and development and manufacturing space in two buildings located in San Diego, California, which was assumed pursuant to the Mykrolis acquisition of Aeronex, Inc. in 2004. Approximately 31,000 square feet of office, research and development and manufacturing space located in Franklin, MA was assumed pursuant to the Mykrolis acquisition of Extraction Systems, Inc. in 2005. The leases for this space run for a term of approximately two years. We maintain a worldwide network of sales, service, repair and cleaning centers in the United States, Germany, France, Japan, Taiwan, Singapore, China (Shanghai) and Korea. Leases for our facilities expire between October 2008 and March 2014. We currently expect to be able to extend the terms of expiring leases or to find suitable replacement facilities on reasonable terms. We believe that our facilities are well-maintained and, except as described above, suitable for their respective operations. Except for approximately 15,000 square feet in our Billerica facility and 90,000 square feet in our Kulim, Malaysia facility, all of our facilities are fully utilized. Item 3. Legal Proceedings. The following discussion provides information regarding certain litigation to which the Company was a party that were pending as of December 31, 2006. As previously disclosed, on March 3, 2003 the Company’s predecessor, Mykrolis Corporation, filed a lawsuit against Pall Corporation in the United States District Court for the District of Massachusetts alleging infringement of two of the Company’s U.S. patents by certain fluid separation systems and related assemblies used in photolithography applications manufactured and sold by the defendant. The Company’s lawsuit also sought a preliminary injunction preventing the defendant from the manufacture, use, sale, offer for sale or importation into the U.S. of any infringing product. On April 30, 2004, the Court issued a preliminary injunction against Pall Corporation and ordered Pall to immediately stop making, using, selling, or offering to sell within the U.S., or importing into the U.S., its PhotoKleen EZD-2 Filter Assembly products or “any colorable imitation” of those products. On January 18, 2005, the Court issued an order holding Pall Corporation in contempt of court 28 for the violation of the preliminary injunction and ordering Pall to disgorge all profits earned from the sale of its PhotoKleen EZD-2 Filter Assembly products and colorable imitations thereof from the date the preliminary injunction was issued through January 12, 2005. In addition, Pall was also ordered to reimburse Mykrolis for certain of its attorney’s fees associated with the contempt and related proceedings. The Court’s order also dissolved the preliminary injunction, effective January 12, 2005, based on certain prior art cited by Pall which it alleged raised questions as to the validity of the patents in suit. On February 17, 2005, the Company filed notice of appeal to the U.S. Circuit Court of Appeals for the Federal Circuit appealing the portion of the Court’s order that dissolved the preliminary injunction and Pall filed a notice of appeal to that court with respect to the finding of contempt and the award of attorneys’ fees; these cross appeals are pending. On April 6, 2006 the Company filed a lawsuit against Pall Corporation in the United States District Court for the District of Massachusetts alleging infringement of the Company’s newly issued U.S. patent No. 7,021,667 by certain filter assembly products used in photolithography applications that are manufactured and sold by the defendant. The Company’s lawsuit also seeks a preliminary injunction preventing the defendant from the manufacture, use, sale, offer for sale or importation into the U.S. of the infringing products. On October 23, 2006 the Company’s motion for preliminary injunction was argued before the court; a decision on this motion is pending. On August 23, 2006 the Company filed a lawsuit against Pall Corporation in the United States District Court for the District of Massachusetts alleging infringement of the Company’s newly issued U.S. patent No. 7,037,424 by certain fluid separation modules and related separation apparatus, including the product known as the EZD-3 Filter Assembly, used in photolithography applications that are manufactured and sold by the defendant. It is believed that the EZD-3 Filter Assembly was introduced into the market by the defendant in response to the action brought by the Company in March of 2003 as described above. This case is currently in the preliminary stages. As previously disclosed, on December 16, 2005 Pall Corporation filed suit against the Company in U.S. District Court for the Eastern District of New York alleging patent infringement. Specifically, the suit alleges infringement of two of plaintiff’s patents by certain of the Company’s filtration products. Both products and their predecessor products have been on the market for a number of years and one is covered by patents held by the Company. The Company intends to vigorously defend this suit and believes that it will ultimately prevail. This case is currently in the discovery stage. Item 4. Submission of Matters to a Vote of Security Holders. None. 29 PART II Item 5. Market for Entegris’ Common Stock, Related Stockholder Matters and Issuer Purchases of Equity Securities. Entegris’ Common Stock, $0.01 par value, trades on the NASDAQ National Market System (NMS) under the symbol “ENTG”; prior to the Merger, Entegris Minnesota’s shares traded on the NMS under the same symbol. The following table sets forth the highest and lowest sale prices of the Company shares during fiscal 2006 and during the four month Transition Period and the highest and lowest sale process of Entegris Minnesota shares at the close of each day, as reported by the NASDAQ-NMS, for the fiscal periods indicated. As of February 6, 2007 there were 881 shareholders of record.

The Company currently intends to retain all available earnings for use in its business or for share repurchase programs and does not anticipate paying any cash dividends in the foreseeable future. On July 27, 2005 the Entegris Board of Directors declared a dividend of one preferred share purchase right for each share of Entegris Common Stock outstanding to shareholders of record on August 8, 2005, payable on August 8, 2005. For a description of the Share Rights Plan see “Other Information” in Item 1 above. Each right entitles the holder to purchase one-hundredth of a preferred share of Entegris at a price of $50. 30 Comparative Stock Performance The following graph compares the cumulative total shareholder return on the common stock of Entegris Minnesota and the Company from August 26, 2001 through December 31, 2006 with cumulative total return of (1) The NASDAQ Composite Index, (2) The Philadelphia Semiconductor Index and (3) a self-constructed peer group of companies. The peer group companies are: ATMI, Inc., Advanced Energy Industries, Inc., Brooks Automation, Inc., Electro Scientific Industries, Inc., FSI International, Inc., MKS Instruments, Inc. and Photronics, Inc. Prior to fiscal 2006 Helix Technology Corporation and prior to fiscal 2005, Nortem Technology N.V. (formerly Metron Technology N.V.) and DuPont Photomasks, Inc. had been included in this peer group; however, they have been removed due to the fact that they were acquired by other companies during the Company’s year ended August 27, 2005 and are no longer U.S. public reporting companies. Since consolidation has rendered the above peer group a small sample, the Company intends to drop this peer group from the comparison next year and to substitute the Philadelphia Semiconductor Index. The graph assumes $100 was invested at the close of trading August 26, 2001 in Entegris, Inc. common stock, the NASDAQ Composite Index the Philadelphia Semiconductor Index and the peer group index listed above and that all dividends are reinvested.

Includes 4,677,268 shares received on September 5, 2006 pursuant to the ASRA and 2,976,444 shares received on September 5, 2006 pursuant to the CASRA. (2) (3) Based on an average purchase price of $10.6900 per share for shares received pursuant to the ASRA, calculated as of September 5, 2006. The Company’s per share purchase price pursuant to the ASRA may be adjusted as of September 4, 2007, based on the volume-weighted average trading price of the stock through that date. (4) Based on an average purchase price $11.8965 for all shares received pursuant to the CASRA as of October 6, 2006. The Company may receive additional shares pursuant to the CASRA at no additional cost depending on movements in the market price of the Company’s common stock through September 4, 2007. (5) The Company made initial payments totaling $100,000,000 to Goldman Sachs under the ASRA and the CASRA. The Company has not repurchased any of its own shares except for those shares acquired pursuant to the ASRA and CASRA and currently has $50,000,000 remaining available for repurchases pursuant to the plan. The total purchase price under the ASRA is subject to adjustment as of September 4, 2007 as described in footnote (3) above. The $50,000,000 reserve for future repurchases may be used to make any additional payments to Goldman Sachs required under the ASRA (described in footnote (3) above) or to repurchase additional shares pursuant to an SEC Rule 10b5-1 Plan to be established by the Company.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. You should read the following discussion and analysis of the Company’s consolidated financial condition and results of operations with the consolidated financial statements and the accompanying notes to the consolidated financial statements included elsewhere in this document. This discussion contains forward-looking statements that involve numerous risks and uncertainties, including, but not limited to, those described in the “FACTORS AND UNCERTAINTIES THAT MAY AFFECT FUTURE RESULTS” section of this Item 7. Our actual results may differ materially from those contained in any forward-looking statements. Overview This overview is not a complete discussion of our financial condition, changes in financial condition and results of operations; it is intended merely to facilitate an understanding of the most salient aspects of our financial 34 condition and operating performance and to provide a context for the discussion that follows. The detailed discussion and analysis that follows must be read in its entirety in order to fully understand our financial condition and results of operations. Entegris, Inc. is a leading provider of materials integrity management products and services that purify, protect and transport the critical materials used in key technology-driven industries. Entegris derives most of its revenue from the sale of products and services to the semiconductor and data storage industries. The Company’s customers consist primarily of semiconductor manufacturers, semiconductor equipment and materials suppliers, and hard disk manufacturers which are served through direct sales efforts, as well as sales and distribution relationships, in North America, Asia, Europe and the Middle East. Effective August 6, 2005 Entegris, Inc., a Minnesota corporation, and Mykrolis Corporation, a Delaware corporation, completed a strategic merger of equals transaction, pursuant to which they were each merged into a new Delaware corporation named Entegris, Inc. to carry on the combined businesses. The transaction was accounted for as an acquisition of Mykrolis by Entegris. With the merger with Mykrolis Corporation, the Company added liquid and gas filters, liquid delivery systems, components and consumables used to precisely measure, deliver, control and purify the process liquids, gases and chemicals that are used in the semiconductor manufacturing process to our materials integrity management product offerings. After the merger with Mykrolis, the Company offers a diverse product portfolio which includes more than 13,000 standard and customized products that we believe provide the most comprehensive offering of materials integrity management products and services to the microelectronics industry. Certain of these products are unit driven and consumable products that rely on the level of semiconductor manufacturing activity to drive growth while others rely on expansion of manufacturing capacity to drive growth. The Company’s unit driven and consumable product class includes wafer shippers, disk shipping containers and test assembly and packaging products, membrane based liquid filters and housings, metal based gas filters and resin based gas purifiers, as well as PVA roller brushes for use in post CMP cleaning applications. The Company’s capital expense driven products include its process carriers that protect the integrity of in-process wafers, components, systems and subsystems that use electro-mechanical, pressure differential and related technologies, to permit semiconductor and other electronics manufacturers to monitor and control the flow and condition of process liquids used in these manufacturing processes. On December 13, 2005, the Company’s board of directors approved a change in fiscal year end from a 52-week or 53-week fiscal year period ending on the last Saturday of August to December 31, effective as of December 31, 2005. As a result, the financial periods presented and discussed in this Annual Report on Form 10-K will be defined as follows: (i) year ended December 31, 2006 representing the twelve months ended December 31, 2006; (ii) four-month transition period ended December 31, 2005 representing the four months ended December 31, 2005; (iii) year ended August 27, 2005 representing the twelve months ended August 27, 2005; and (iv) year ended August 28, 2004 representing the twelve months ended August 28, 2004 Key operating factors Key factors, which management believes have the largest impact on the overall results of operations of Entegris, Inc. include: • Level of sales Since a large portion of the Company’s product costs (excepting raw materials, purchased components and direct labor) are largely fixed in the short/medium term, an increase or decrease in sales affects gross profits and overall profitability significantly. Also, increases or decreases in sales and operating profitability affects certain costs such as incentive compensation, commissions and donations, all of which are highly variable in nature. • Variable margin on sales The Company’s variable margin on sales is determined by selling prices and the cost of manufacturing and raw materials. This is also affected by a number of factors, which include the Company’s sale mix, purchase prices of raw material (especially resin and purchased components), competition, both domestic and international, direct labor costs, and the efficiency of the Company’s production operations, among others. 35 • Fixed cost structure The Company’s fixed cost structure is significant. Increases or decreases in sales have a large impact on profitability. There are a number of large fixed or semi-fixed cost components, which include salaries, indirect labor, and benefits, and depreciation and amortization. It is not possible to vary these costs easily in the short term as volumes fluctuate. Thus changes in sales volumes can affect the usage and productivity of these cost components and can have a large effect on the Company’s results of operations. Overall Summary of Financial Results for the Year Ended December 31, 2006 For the year ended December 31, 2006 (2006), net sales were $678.7 million, up $235.9 million, or 53.3%, from sales reported for the year ended December 31, 2005 (2005). The increase was principally driven by the benefit of a full year of sales from Mykrolis operations, acquired on August 6, 2005, with incremental sales of approximately $192.0 million. The sales comparison is adversely affected by approximately $4.5 million due to the year-over-year currency fluctuations, principally related to the Japanese yen, versus the U.S. dollar. Reflecting the year-over-year sales increase, the Company reported higher gross profit and improved gross margins. The Company’s gross margin in 2006 was 45.1% versus 36.4% a year earlier. The absence of a $23.8 million incremental cost of sales charge recorded in 2005 associated with the fair market value write-up of inventory acquired in the merger with Mykrolis accounts for about two-thirds of the year-over-year improvement in 2006. The Company’s selling, general and administrative (SG&A) expenses increased $32.2 million in 2006. The increase in SG&A costs primarily reflects the addition of SG&A expenses associated with Mykrolis’ infrastructure offset by lower SG&A expenses in 2006 related to the completion of merger-related integration activities when compared to 2005, as well as the benefit of cost containment measures initiated during the latter half of 2006. The Company reported income from continuing operations of $62.4 million for 2006 compared to a loss of $5.1 million for 2005. Income from continuing operations increased due to the higher sales and gross profit levels, and lower levels of merger-related integration expenses. During 2006, the Company generated cash of $95.9 million from operations as the cash generated by the Company’s net earnings and non-cash charges exceeded the effect of working capital changes (increases in accounts receivable and inventory along with decreases in accounts payable and accrued liabilities). Cash, cash equivalents and short-term investments were $275.0 million at December 31, 2006 compared with $274.4 million at December 31, 2005. Critical Accounting Policies Management’s discussion and analysis of financial condition and results of operations are based upon the Company’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these consolidated financial statements requires the Company to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. At each balance sheet date, management evaluates its estimates, including, but not limited to, those related to accounts receivable, warranty and sales return obligations, inventories, long-lived assets, and income taxes. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. The critical accounting policies affected most significantly by estimates, assumptions and judgments used in the preparation of the Company’s consolidated financial statements are discussed below. Net Sales The Company’s net sales consist of revenue from sales of products net of trade discounts and allowances. Revenue for product sales is recognized upon delivery, when title and risk of loss have been transferred to the customer; collectibility is reasonably assured, and pricing is fixed or determinable. In most transactions, the Company has no obligations to its customers after the date products are shipped other than 36 pursuant to warranty obligations. In the event that significant post- shipment obligations or uncertainties exist such as customer acceptance, revenue recognition is deferred as appropriate until such obligations are fulfilled or the uncertainties are resolved. Accounts Receivable-Related Valuation Accounts The Company maintains allowances for doubtful accounts and for sales returns and allowances. Significant management judgments and estimates must be made and used in connection with establishing these valuation accounts. Material differences could result in the amount and timing of the Company’s results of operations for any period if we made different judgments or utilized different estimates. In addition, actual results could be different from the Company’s current estimates, possibly resulting in increased future charges to earnings. The Company provides an allowance for doubtful accounts for all individual receivables judged to be unlikely for collection. For all other accounts receivable, the Company records an allowance for doubtful accounts based on a combination of factors. Specifically, management analyzes the age of receivable balances, historical bad debts write-off experience, industry and geographic concentrations of customers, general customer creditworthiness and current economic trends when determining its allowance for doubtful accounts. The Company’s allowance for doubtful accounts was $0.8 million and $1.4 million at December 31, 2006 and December 31, 2005, respectively. An allowance for sales returns and allowances is established based on historical trends and current trends in product returns. At December 31, 2006 and December 31, 2005, the Company’s reserve for sales returns and allowances was $1.8 million and $0.9 million, respectively. Inventory Valuation The Company uses certain estimates and judgments to properly value inventory. In general, the Company’s inventories are recorded at the lower of manufacturing cost or market value. Each quarter, the Company evaluates its ending inventories for obsolescence and excess quantities. This evaluation includes analyses of inventory levels, historical write-off trends, expected product lives, sales levels by product and projections of future sales demand. Inventories that are considered obsolete are written off or a valuation allowance is recorded to establish a new carrying value for the identified items. In addition, valuation allowances are established for inventory quantities in excess of forecasted demand. Inventory valuation allowances were $10.2 million at December 31, 2006 compared to $8.1 million at December 31, 2005. The Company’s inventories comprise materials and products subject to technological obsolescence, which are sold in highly competitive industries. If future demand or market conditions are less favorable than current analyses, additional inventory write-downs or valuation allowances may be required and would be reflected in cost of sales in the period the revision is made. Impairment of Long-Lived Assets The Company routinely considers whether indicators of impairment of its property and equipment assets, particularly its molding equipment, are present. If such indicators are present, it is determined whether the sum of the estimated undiscounted cash flows attributable to the assets in question is less than their carrying value. If less, an impairment loss is recognized based on the excess of the carrying amount of the assets over their respective fair values. Fair value is determined by discounting estimated future cash flows, appraisals or other methods deemed appropriate. If the assets determined to be impaired are to be held and used, the Company recognizes an impairment charge to the extent the present value of anticipated net cash flows attributable to the assets are less than the assets’ carrying value. The fair value of the assets then becomes the assets’ new carrying value, which we depreciate over the remaining estimated useful life of the assets. The Company tests goodwill for impairment on an annual basis. The Company assesses the impairment of amortizable intangible assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors considered important which could trigger an impairment review, and potentially an impairment charge, include the following: • significant underperformance relative to historical or projected future operating results; 37 • • • significant changes in the manner of use of the acquired assets or the Company’s overall business strategy; significant negative industry or economic trends; and significant decline in the Company’s stock price for a sustained period changing the Company’s market capitalization relative to its net book value; Income Taxes In the preparation of the Company’s consolidated financial statements, management is required to estimate income taxes in each of the jurisdictions in which the Company operates. This process involves estimating actual current tax exposures together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in the Company’s consolidated balance sheet. The Company intends to continue to reinvest its undistributed international earnings in its international operations; therefore, no U.S. tax has been recorded to cover the repatriation of such undistributed earnings. The Company has significant amounts of deferred tax assets. Management reviews its deferred tax assets for recoverability on a quarterly basis and assesses the need for valuation allowances. These deferred tax assets are evaluated by considering historical levels of income, estimates of future taxable income streams and the impact of tax planning strategies. A valuation allowance is recorded to reduce deferred tax assets when it is determined that it is more likely than not that the Company would not be able to realize all or part of its deferred tax assets. The Company carried a valuation allowance of $0.7 million and $2.2 million against its deferred tax assets at December 31, 2006 and December 31, 2005, respectively, in connection with a portion of a capital loss carryforward related to the Company’s discontinued operations that more likely than not will not be realized. The change in the valuation allowance resulted from the resolution of a matter with respect to the characterization of certain gains and losses. Warranty Claims Accrual The Company records a liability for estimated warranty claims. The amount of the accrual is based on historical claims data by product group and other factors. Claims could be materially different from actual results for a variety of reasons, including a change in product failure rates and service delivery costs incurred in correcting a product failure, manufacturing changes that could impact product quality, or as yet unrecognized defects in products sold. At December 31, 2006 and December 31, 2005, the Company’s accrual for estimated future warranty costs was $2.0 million and $2.1 million, respectively. Business Acquisitions The Company accounts for acquired businesses using the purchase method of accounting which requires that the assets acquired and liabilities assumed be recorded at the date of acquisition at their respective fair values. The judgments made in determining the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact net income. Accordingly, for significant items, the Company typically obtains assistance from independent valuation specialists. There are several methods that can be used to determine the fair value of assets acquired and liabilities assumed. For intangible assets, the Company normally utilizes the “income method.” This method starts with a forecast of all of the expected future net cash flows. These cash flows are then adjusted to present value by applying an appropriate discount rate that reflects the risk factors associated with the cash flow streams. Some of the more significant estimates and assumptions inherent in the income method or other methods include the projected future cash flows (including timing) and the discount rate reflecting the risks inherent in the future cash flows. Determining the useful life of an intangible asset also requires judgment. For example, different types of intangible assets will have different useful lives and certain assets may even be considered to have indefinite useful lives. All of these judgments and estimates can significantly impact net income. 38 Results of Operations Twelve months ended December 31, 2006 compared to twelve months ended December 31, 2005 (Unaudited) The following table sets forth the results of operations and the relationship between various components of operations, stated as a percent of net sales, for the years ended December 31, 2006 and December 31, 2005.

The increase in net sales reflects the inclusion of sales from the former Mykrolis operations for the full year in 2006 versus only the five-month period from August 6, 2005 through December 31, 2005 for the prior period. Such incremental sales totaled $192.0 million and accounted for approximately 80% of the year–over-year increase. Net sales for fiscal 2006 included unfavorable foreign currency effects, principally related to the Japanese yen, versus the U.S. dollar in the amount of $4.5 million. On a geographic basis, total sales to North America were 27%, Asia Pacific 33%, Europe 15% and Japan 25% in 2006. Demand drivers for the Company’s business primarily are comprised of semiconductor fab utilization and production (unit-driven) as well as capital spending for new or upgraded semiconductor fabrication facilities (capital-driven). The Company analyzes sales of its products by these two key drivers. Sales of unit driven products represented 59% of sales and capital-driven products represented 41% of total sales in 2006. This compares to a unit driven to capital driven ratio of 60:40 for the year ended December 31, 2005. Sales of unit-driven products grew in 2006 as semiconductor fab utilization rates remained strong and stable. Unit-driven products have average lives of less than 18 months or need to be replaced based on usage levels. These products include liquid filters used in the photolithography, CMP and wet, etch and clean processes, and in wafer shippers, used to ship raw wafers, particularly at wafer sizes of 150mm and below, as well as in chip trays and data storage components used to ship 65mm and 95mm disk drives. Demand for liquid filters remained relatively stable for most of these semiconductor applications, but sales of these products to non-semiconductor customers declined modestly. Sales of wafer shippers increased modestly due to higher sales of 200mm wafer shipper products. Sales of disk shippers for data storage products were also higher, as the market for 95mm devices remained strong. 39 Year over year sales of capital driven products generally improved in 2006, reflecting strong sales during the first half of the year and a decline during the second half of 2006 reflecting a general slowing of the industry, particularly in North America. Capital driven products include wafer process carriers, gas micro contamination control systems, used in the deployment of advanced photolithography processes, fluid handling systems including dispense pumps used in the photolithography process, and integrated liquid flow controllers used in various processes around the fab. Sales of liquid systems grew during the first half of the year, but declined later in 2006 reflecting a general slowing in the industry. Wafer transport products, such as 300mm FOUP products, also reflected slower capital spending, particularly at some North American customers. Sales of gas microcontamination control products reached the all-time high in 2006, reflecting the market acceptance of the Company’s gas purification systems and liquid lens system used on advanced lithography steppers. Sequentially, sales for the fourth quarter of 2006 were 1% lower than the third quarter of 2006 due to lower sales of capital-driven products. Unit-driven sales remained stable reflecting flat levels of wafer starts and semiconductor production. This was in contrast to significantly lower sales of capital-driven products due in part to softening in demand, particularly from North American customers. Gross profit Gross profit for the year ended December 31, 2006 increased by $144.9 million to $306.1 million, an increase of 89.8% from the $161.3 million for the comparable 2005 period. The gross margin percentage for 2006 was 45.1% versus 36.4% for the comparable 2005 period. The gross profit and gross margin improvements for the year ended December 31,2006 compared to the same period a year ago were mainly due to the addition of the former Mykrolis operations, particularly the inclusion of sales of gas micro contamination and liquid micro contamination product lines as these products typically carry higher gross margins than the Company’s other products. The Company also benefited from improved sales levels resulting in improved utilization of its manufacturing facilities. Prices for raw materials were relatively stable sequentially and compared to the year-ago period. Gross profit in 2006 was reduced by costs of $2.8 million incurred in connection with the consolidation of manufacturing facilities in the U.S., Germany and Japan. Offsetting these charges to 2006 gross profit was a gain of $0.7 million on the sale of a facility recognized during the second quarter of 2006. Gross profit in the third and fourth quarters of 2006 was lower than the strong levels achieved earlier in the year due to manufacturing inefficiencies experienced at a North American plant in the third quarter and expenses incurred in the fourth quarter in connection with a comprehensive worldwide review of the Company’s manufacturing operations to identify and resolve manufacturing inefficiencies. Gross profit in 2005 was significantly affected by the inclusion of $23.8 million in incremental cost of sales charge associated with the fair market value write-up of inventory acquired in the merger with Mykrolis. The inventory write-up was recorded as part of the purchase price allocation and was charged to cost of sales over inventory turns of the acquired inventory during the third and fourth quarters of 2005. Also during 2005, the Company incurred costs of $8.4 million associated with the realignment of manufacturing facilities in the U.S., Germany and Japan and its production and administrative activities, including $3.7 million in accelerated depreciation and impairment charges associated with assets sold or in connection with realignment activities. Selling, general and administrative expenses Selling, general and administrative (SG&A) expenses of $189.8 million for 2006 increased $32.2 million, or 20.4% as compared to $157.6 million in the comparable period a year ago. SG&A expenses, as a percent of net sales, fell to 28.0% from 35.6% a year earlier. The lower SG&A costs as a percent of net sales reflects the benefit of cost reductions associated with the merging of the two entities. The year-over-year increase in SG&A costs reflect the addition of SG&A expenses associated with Mykrolis’ infrastructure as well as increased amortization of intangibles of $7.4 million. Costs of $12.1 million were 40 incurred by the Company in connection with the integration and realignment activities associated with the Mykrolis merger compared to $23.4 million in 2005. The costs included in the latter category generally relate to expenses incurred to integrate Mykrolis’ operations and systems into the Company’s pre-existing operations and systems. These costs include, but are not limited to, the integration of information systems, employee benefits and compensation, accounting/finance, tax, treasury, risk management, compliance, administrative services, sales and marketing and other functions and includes severance and retention costs. SG&A costs fell during the second half 2006 as cost containment measures were put in place in the face of slowing sales and as integration activities were completed. Engineering, research and development expenses Engineering, research and development (ER&D) expenses rose by $12.6 million, or 47.9%, to $38.8 million in fiscal 2006 as compared to $26.2 million for the year ended December 31, 2005. The increases mainly reflect the inclusion of ER&D expenses associated with former Mykrolis operations. ER&D expenses as a percent of net sales were 5.7% compared to 5.9% a year ago. The Company continues to focus on supporting current product lines, and developing new products and manufacturing technologies. Interest income, net Net interest income was $9.2 million in fiscal 2006 compared to $4.5 million in the year-ago period. The increases reflect the considerably higher rates of interest available on the Company’s investments in short-term debt securities as well as the higher average net invested balance compared to the year-ago period, associated in part with the cash and short-term investments acquired in the Mykrolis merger. Income tax expense The Company recorded income tax expense of $26.5 million in fiscal 2006 compared to an income tax benefit of $10.9 million for the comparable period a year ago. The effective tax rate was 30.0% in fiscal 2006 compared with a 68.8% rate a year earlier. The Company’s 2006 tax rate was lower than statutory rates due to the benefits associated with export activities and a tax holiday in Malaysia whereby as a result of employment commitments and capital investments made by the Company, income from certain manufacturing activities in Malaysia was exempt from tax with tax benefits in 2006 in the amount of $2.8 million. In 2005, the Company benefited from a tax holiday in Malaysia whereby as a result of employment and R&D expenditure commitments made by the Company, income from certain manufacturing activities in Malaysia was exempt from tax with tax benefits of $1.0 million. Discontinued operations The Company’s businesses classified as discontinued operations recorded nominal losses before income taxes for fiscal 2006. The year-to-date results of income from discontinued operations included a tax benefit of $1.6 million recorded in the first quarter of 2006 related to the change in the deferred tax asset valuation allowance resulting from the resolution of a matter with respect to the characterization of certain gains and losses. Net income The Company recorded net income of $63.5 million, or $0.46 per diluted share, in fiscal 2006, compared to a net loss of $15.5 million, or $0.16 per diluted share, in the comparable 2005 period. Income from continuing operations for fiscal 2006 was $62.4 million, or $0.45 per diluted share, compared to a net loss of $5.1 million, or $0.05 per diluted share, in the year ago period. 41 Four Months Ended December 31, 2005 Compared To Four Months Ended December 31, 2004 (Unaudited) The following table sets forth the results of operations and the relationship between various components of operations, stated as a percent of net sales, for the four months ended December 31, 2005 and December 31, 2004. The Company’s historical financial data were derived from its consolidated financial statements and related notes included elsewhere in this annual report.

Sales from Mykrolis operations totaled $89.6 million, accounting for slightly more than the overall period-over-period increase. Sales were adversely affected by approximately $3.5 million due to the weakening of international currencies versus the U.S. dollar, most notably in Japan. On a geographic basis, total regional sales to North America were 31%, Asia Pacific 33%, Europe 14% and Japan 22%. Industry indicators during the 2005 period were largely positive. Semiconductor device makers and foundries reported continued high fab utilization rates, both at the advanced technology nodes and for NAND flash and other memory devices. Capital spending was also generally favorable. These trends were reflected across unit-driven products. In particular, sales of liquid filtration and purification products, which represent almost half of unit-driven sales, improved over the comparable period a year ago. Strength in Japan and North America was offset by relative weakness in Europe, whose order trends typically trail those in other geographies. Sales of wafer shippers rose during the period, driven by demand for product for 200mm and below. Other unit- driven products were mixed. Strong sales of gas microcontamination filters and purifiers, which are used on a broad spectrum of gas and vacuum based tools, offset lower sales of shippers for data storage devices and matrix trays for finished electronic products. Among capital-driven products, sales of 300mm wafer carriers improved over the comparable period a year earlier. Sales of these products are primarily driven by the timing of new fab construction, and as such, demand can be variable from period to period. Sales of liquid systems products were also higher than a year ago. Gross profit Gross profit in the four months ended December 31, 2005 increased by $21.4 million to $70.0 million, an increase of 44% from the $48.6 million reported in the four months ended December 31, 2004. The gross margin percentage for the four months ended December 31, 2005, was 34.6 % versus 41.3% in the comparable period of 2004. 42 The gross margin percentage figure for the four months ended December 31, 2005, was significantly below the figure for the same period in the prior year for a number of reasons. The main factor was the $17.8 million incremental cost of sales charge associated with the fair market value write-up of inventory acquired in the merger with Mykrolis. The inventory write-up was recorded as part of the purchase price allocation and was charged to cost of sales over inventory turns of the acquired inventory and was fully expensed by the end of the quarter ended November 26, 2005. Costs of $4.8 million associated with the consolidation of manufacturing facilities in the U.S., Germany and Japan also reduced gross profit. Although price increases for resins recently began to moderate, on a year-over-year basis, the Company’s gross margin was lower due to higher material costs for certain products. Selling, general and administrative expenses Selling, general and administrative (SG&A) expenses increased $45.9 million, or 144%, to $77.8 million in the four months ended December 31, 2005, up from $31.9 million in the comparable four-month period a year earlier. Due to the magnitude of the increase, SG&A expenses, as a percent of net sales, rose to 38.5% from 27.1% a year earlier. The increase in SG&A costs reflects the addition of SG&A expenses of $31.0 million associated with Mykrolis’ infrastructure and increased amortization of intangibles of $4.7 million as well as costs of $11.3 million incurred by the Company in connection with the integration activities associated with the Mykrolis merger. The costs included in this category generally relate to expenses incurred to integrate Mykrolis’ operations and systems into the Company’s pre-existing operations and systems. These costs include, but are not limited to, the integration of information systems, employee benefits and compensation, accounting/finance, tax, treasury, risk management, compliance, administrative services, sales and marketing and other functions and includes severance and retention costs. The year-over-year increase also includes incremental share-based compensation expense of $9.6 million. Engineering, research and development expenses Engineering, research and development (ER&D) expenses were $13.9 million in the four months ended December 31, 2005, up 122% from $6.3 million in the four months ended December 31, 2004. ER&D expenses, as a percent of net sales, increased to 6.9% from 5.3%, reflecting the inclusion of Mykrolis ER&D expenses. The Company continued to focus on the support of current product lines, and the development of new products and manufacturing technologies. Interest income, net Net interest income of $2.4 million in the four months ended December 31, 2005 compared to $0.5 million in the same four-month period a year ago. The increase reflects the higher rates of interest available on the Company’s investments in short-term debt securities as well as the higher average net invested balance compared to the year-ago period, associated in part with the investment funds acquired in the Mykrolis merger. Income tax expense The Company recorded an income tax benefit of $9.0 million in the four months ended December 31, 2005 compared to income tax expense of $3.0 million in the four months ended December 31, 2004. The effective tax rate was (46.5)% in the 2005 period, compared to 28.2% in the 2004 period. During in the four months ended December 31, 2005, the Company recorded a tax benefit $1.1 million, plus interest, related to the refund of certain Minnesota corporate income taxes previously paid for fiscal years 2000 and 2001 based upon recent court rulings. In both periods, the Company’s effective tax rate benefited from a tax benefit associated with export activities and a tax credit associated with research and development (R&D) activities. In addition, the Company benefited from a tax holiday in Malaysia whereby as a result of employment and R&D expenditure commitments made by the Company, income from certain manufacturing activities in Malaysia was exempt from tax with tax benefits in the four months ended December 31, 2005 in the amount of $0.2 million. Income tax expense in the four months ended December 31, 2004 also included a $0.5 million tax benefit that was recorded in connection with the resolution of a U.S. Federal income tax refund claim made by the Company. Discontinued operations The Company’s businesses classified as discontinued operations recorded a net loss of $8.0 million, net of tax, in the four months ended December 31, 2005. The results included impairment charges of $6.7 million, net of tax, associated with write-downs of long-lived assets to fair value less cost to sell. These product lines were sold in late calendar 2005 and the first quarter of calendar 2006. 43 Net (loss) income The Company recorded a net loss of $18.3 million, or $0.14 per diluted share, in the four- month period ended December 31, 2005 compared to net income of $6.6 million, or $0.09 per diluted share, in the four-month period ended December 31, 2004. The loss from continuing operations for the 2005 four-month period was $10.3 million, or $0.08 per share, compared to net income of $7.6 million, or $0.10 per share, in the 2004 four-month period. Fiscal 2005 Compared to Fiscal 2004 The following table sets forth the relationship between various components of operations, stated as a percent of net sales, for the years ended August 27, 2005 (fiscal 2005) and August 28, 2004 (fiscal 2004).

The slight increase reflected improvement in certain product lines and the impact of the merger with Mykrolis which closed on August 6, 2005, three weeks prior to the end of the Company’s fiscal year. Approximately two-thirds of the sales increase for 2005 was associated with the Mykrolis merger. The semiconductor market generated about 75% of the Company’s overall sales for fiscal 2005, compared to about 77% in fiscal 2004. Exclusive of the Mykrolis sales recorded late in fiscal 2005, sales of semiconductor products decreased by 3% from fiscal 2004 to 2005. Both unit-driven product lines such as wafer shippers, and test, assembly and packaging products and capital-spending driven products, such as wafer and reticle carrier products and fluid handling products saw slight sales declines. During fiscal 2005, the Company’s data storage products increased by 32% as customers experienced significant increased demand for a wide range of consumer driven electronic products. The increase in sales was particularly driven by results in the first three quarters of the fiscal year with sales moderating in the fourth quarter of the fiscal 2005. Sales of services rose 30% from fiscal 2004. The increase reflects growth from a service facility acquired in France in the third quarter of fiscal 2004 along with increased sales of equipment used to clean wafer shippers, disk carriers and other shipping products. During fiscal 2005 sales in all geographies increased with the highest increase in the Asia-Pacific region. The fiscal 2005 regional sales breakdown, as a percentage of total sales, was as follows: North America 37%, Asia- Pacific 32%, Europe 16% and Japan 15%. 44 Gross profit Gross profit in fiscal 2005 decreased by 7.1% to $139.6 million, compared to $150.3 million in fiscal 2004. As a percentage of net sales, the fiscal 2005 gross margin was 39.0%, compared to 44.6% in 2004. The reductions in the fiscal 2005 gross margin percentage figures were primarily the result of higher resin prices, estimated at slightly over 100 basis points; a change in product mix to some relatively lower margin wafer process products, the fourth quarter $5.9 million reduction in gross profit associated with the write-up of inventory to fair value in connection with the Merger with Mykrolis and costs of $3.6 million associated with consolidation of manufacturing facilities, mainly incurred in the fourth quarter. Selling, general and administrative expenses (SG&A) SG&A expenses increased $18.3 million, or 19.6%, to $111.6 million in fiscal 2005, up from $93.3 million in fiscal 2004. SG&A costs, as a percent of net sales, increased to 31.2% from 27.7%. This increase mainly reflects costs of $12.1 incurred by the Company in connection with the merger with Mykrolis and includes severance and retention costs and costs associated with integration of the two operations as well the additional SG&A expenses recorded by Mykrolis after the date of the Merger. Engineering, research and development expenses (ER&D) ER&D expenses were essentially flat in 2005 at $18.5 million compared to $18.8 million in 2004. Due to the slight decrease in ER&D expenses and the Company’s higher net sales, such costs as a percent of net sales, decreased to 5.2% from 5.6%. The Company’s ER&D efforts continued to focus on the support or extension of current product lines, and the development of new products and manufacturing technologies. Operating profit Operating profit, stated as a percent of net sales, was 2.6% for fiscal 2005, compared to 11.3% in fiscal 2004. The decline in fiscal 2005 was mainly due to lower gross profit and higher SG&A expenses as described above. Interest income, net The Company reported net interest income was $2.5 million in fiscal 2005 as compared with $0.3 million in fiscal 2004. The increases reflect higher average net invested balances and higher rates of interest available on the Company’s investment in debt securities, when compared to a year ago. In addition, interest income in the third quarter of fiscal 2005 included $0.2 million related to interest on a tax refund received during the period. Other (income) expense, net Other income was $2.1 million in fiscal 2005 compared to $1.1 million in fiscal 2004. Other income in fiscal 2005 included gains of $2.9 million associated with the sale of about 1.1 million shares of Nortem N.V. common stock as described in Note 6 to the Company’s consolidated financials statements. Other income in fiscal 2004 included gains of $1.1 million associated with the sale of an aggregate 512,800 shares of Nortem N.V. common stock made periodically over the course of fiscal 2004. The Company also recorded foreign currency remeasurement losses of $0.9 million in fiscal 2005 compared to foreign currency remeasurement losses of $0.2 million in fiscal 2004. Income tax (benefit) expense The Company recorded an income tax expense of $1.1 million in fiscal 2005 compared to income tax expense of $12.5 million for fiscal 2004. The effective tax rate for fiscal 2005 was 7.7% compared to 31.6 % in fiscal 2004. The Company’s effective tax rate in fiscal 2005 is lower than the statutory federal rate of 35% in the United States due to a tax benefit associated with export activities, a tax benefit from the Company’s investment in tax exempt securities, a tax credit associated with research and development (R&D) activities, and a benefit of $1.4 million from the resolution of tax contingencies. In addition, the Company benefited from a tax holiday in Malaysia whereby as a result of employment and R&D expenditure commitments made by the Company, income from certain manufacturing activities in Malaysia was exempt from tax with tax benefits in fiscal 2005 in the amount of $1.0 million compared to $0.7 million in fiscal 2004. The Company’s effective tax rate in fiscal 2004 was lower than the statutory federal rate of 35% in the United States due to lower taxes on foreign operations, a tax benefit associated with export activities, and a tax credit associated with R&D activities. 45 Quarterly Results of Operations The following table presents selected data from the Company’s consolidated statements of operations for the eight quarters and four-month transition period ended December 31, 2006.

Our quarterly results of operations have been, and will likely continue to be, subject to significant fluctuations due to a variety of factors, a number of which are beyond the Company’s control. Liquidity and Capital Resources The Company has historically financed its operations and capital requirements through cash flow from operating activities, long-term loans, lease financing and borrowings under domestic and international short-term lines of credit. In August 2005, the company financed its merger with Mykrolis Corporation through the issuance of common stock and stock options. Operating activities Net cash flow provided by operating activities totaled $95.9 million in for the year ended December 31, 2006. Cash flow primarily related to non-cash charges, including depreciation and amortization of $43.7 million, and share-based compensation expense of $14.8 million. Offsetting these items was the impact of changes in operating assets and liabilities, most notably receivables and inventory increases and a decrease in accounts payable. 46 Net cash flow provided by operating activities totaled $23.4 million in the four months ended December 31, 2005. The Company’s net loss from continuing operations of $10.3 million was offset by various noncash charges, including depreciation and amortization of $14.0 million, the incremental cost of sales charge of $17.8 million associated with the write-up of inventory and share-based compensation expense of $11.1 million. Operating cash flow was only nominally affected by the impact of changes in working capital accounts. Working capital stood at $449.7 million at December 31, 2006, including $154.8 million in cash and cash equivalents, and short-term investments of $120.2 million. During 2006, accounts receivable, net of foreign currency translation adjustments, increased by $16.4 million, reflecting the increase in net sales levels. The Company’s days sales outstanding stood at 70 days compared to 69 days at the beginning of the year. Inventories rose by $23.2 million from December 31, 2005 due to a general increase in production activity associated with higher order and sales levels, and increases in inventories at various locations worldwide related to a change in distribution model and in order to improve customer delivery times. The increase was also due to inventory builds to support the Company’s manufacturing facility consolidations. Investing activities Net cash flow used in investing activities totaled $16.5 million in the twelve months ended December 31, 2006. Acquisition of property and equipment totaled $30.0 million, primarily for additions of manufacturing equipment, tooling and information systems, and the expansion of the Company’s Kulim, Malayisia facility in anticipation of moving the manufacture of certain products to Kulim, as well as expanding engineering and applications support capabilities there. The Company currently expects total capital expenditures of approximately $35 million for calendar 2007. Proceeds of $3.9 million from the sale of various property and equipment were recorded in the twelve months ended December 31, 2006. During the year ended December 31, 2006, short term investments in the amount of $11.2 million, net of purchases, matured. Short-term investments stood at $120.2 million at December 31, 2006. Net cash used in investing activities totaled $13.1 million for the four months ended December 31, 2005. Acquisition of property and equipment of $10.3 million, primarily for additions of manufacturing, computer and laboratory equipment. Financing activities Net cash used in financing activities totaled $80.0 million during fiscal 2006. The Company made payments of $3.1 million on borrowings. No proceeds from new borrowings were received during the current year. The Company received proceeds of $20.0 million in connection with common shares issued under the Company’s stock option and employee stock purchase plans. On August 21, 2006 the Company’s Board of Directors authorized a share repurchase program of up to $150 million over the succeeding 12 to 18 months. In connection with the share repurchase program the Company entered into an accelerated share repurchase agreement (ASRA) and a collared accelerated share repurchase agreement (CASRA) with Goldman, Sachs & Co. (GS) on August 30, 2006. Under the ASRA, which was effective as of August 30, 2006, the Company acquired 4,677,268 shares of common stock on September 5, 2006 from GS for $50.0 million. The transaction was accounted for as a share retirement with common stock, paid-in capital and retained earnings reduced by $47 thousand, $28.2 million, and $21.7 million, respectively. Under the CASRA, the Company paid $50.0 million for a prepaid forward contract, which was effective August 30, 2006, to repurchase the Company’s common stock. The Company received deliveries of common stock of 3.0 million shares and 1.2 million shares on September 5, 2006 and October 6, 2006, respectively. The transaction was accounted for as a share retirement with common stock, paid-in capital and retained earnings reduced by $42 thousand, $25.2 million, and $19.8 million, respectively. $5.0 million of the $50.0 million payment is reflected as a prepaid forward contract for share repurchase in shareholders’ equity, which will be credited as the Company receives additional shares under the CASRA. 47 Under both the accelerated share repurchase (ASRA) and the collared accelerated share repurchase agreements (CASRA), GS may repurchase an equivalent number of shares in the open market through September 4, 2007. At that date, the Company’s price under the ASRA will be adjusted up or down based on the volume-weighted average price of the stock during this period. Such adjustment may be settled in cash or stock at the Company’s discretion. The Company may also receive additional shares pursuant to the CASRA, depending on movements in the market price of the Company’s common stock. The Company financed the ASRA and CASRA with its available cash equivalents and short-term investments. Cash used in financing activities totaled $15.4 million for the four month transition period ended December 31, 2005. Principal payments on short-term borrowings and long-term debt were $22.9 million. Proceeds from borrowings of $3.5 million and proceeds from the issuance of common stock of $3.8 million partially offset this cash outflow. As of December 31, 2006, the Company’s sources of available funds comprised $154.8 million in cash and cash equivalents, $120.2 million in short-term investments, as well as funds available under various credit facilities. Entegris has an unsecured revolving credit agreement with one domestic commercial bank with aggregate borrowing capacity of $10 million, with no borrowings outstanding at December 31, 2006 and lines of credit with three international banks that provide for borrowings of currencies for the Company’s overseas subsidiaries, equivalent to an aggregate of approximately $4.8 million. There were no borrowings outstanding on these lines of credit at December 31, 2006. The Company’s unsecured revolving credit agreement, which expires in May 2008, allows for aggregate borrowings of up to $10.0 million with interest at Eurodollar rates plus 0.875%. Under the unsecured revolving credit agreement, the Company is prohibited from paying cash dividends. The Company is also subject to, and is in compliance with, certain financial covenants including a leverage ratio of funded debt to EBITDA (as defined therein) of not more than 2.25 to 1.00. In addition, the Company must maintain a calculated consolidated tangible net worth, which, as of December 31, 2006, was $294.0 million, while also maintaining consolidated aggregate amounts of cash and cash equivalents (which under the agreement may also include auction rate securities classified as short-term investments) of not less than $75.0 million. At December 31, 2006, the Company’s shareholders’ equity stood at $1,016.0 million, up slightly from $1,012.8 million at the beginning of the year. This change reflects the Company’s net earnings of $63.5 million, the proceeds of $20.0 million received in connection with shares issued under the Company’s stock option and stock purchase plans, and the increase in additional paid-in capital of $14.8 million associated with the recording of share-based compensation expense, offset in part by the $100.0 million repurchase of the Company’s common stock. The Company believes that its cash and cash equivalents, short-term investments, cash flow from operations and available credit facilities will be sufficient to meet its working capital and investment requirements for the next 12 months. However, future growth, including potential acquisitions, may require the Company to raise capital through additional equity or debt financing. There can be no assurance that any such financing would be available on commercially acceptable terms. 48 The following table summarizes the maturities of the Company’s significant financial obligations: (In thousands) Total 2007 2008 2009 2010 2011 Thereafter Maturity by fiscal year Contractual obligations related to off-balance sheet arrangements: Operating leases . . . . . . . . . . . . . . . . . . . . . .

The Company’s interest-bearing cash equivalents and short-term investments, and long-term debt and short-term borrowings are subject to interest rate fluctuations. Most of its long-term debt at December 31, 2006 carries fixed rates of interest. The Company’s cash equivalents and short-term investments are debt instruments with maturities of 24 months or less. A 100 basis point change in interest rates would potentially increase or decrease annual net income by approximately $1.7 million annually. The cash flows and earnings of the Company’s foreign-based operations are subject to fluctuations in foreign exchange rates. The Company occasionally uses derivative financial instruments to manage the foreign currency exchange rate risks associated with its foreign-based operations. At December 31, 2006, the Company was party to forward contracts to deliver Japanese yen, Taiwanese dollars, Euros, Korean won, Malaysia ringgits, and Singapore dollars with notional values of approximately $10.0 million, $18.7 million, $16.0 million, $2.0 million, $8.0 million and $3.6 million, respectively. A hypothetical 10% change in the foreign currency exchange rates would potentially result in exchange gains or losses that would increase or decrease net income by approximately $3.4 million. Impact of Inflation The Company’s consolidated financial statements are prepared on a historical cost basis, which does not completely account for the effects of inflation. Material and labor expenses are the Company’s primary costs. The cost of certain materials, including polymers and stainless steel, were flat compared to one year ago due to increased production capacity of suppliers and relatively stable oil prices. Entegris expects the cost of these materials to increase in the upcoming fiscal year due to tightening of production capacity of its suppliers and a projected increase in oil prices. Labor costs, including taxes and fringe benefits rose slightly in fiscal 2006 and moderate increases also can be reasonably anticipated for fiscal 2007. The Company’s products are sold under contractual arrangements with our large customers and at current market prices to other customers. Consequently, the Company can adjust its selling prices, to the extent allowed by competition and contractual arrangements, to reflect cost increases caused by inflation. However, many of these cost increases may not be recoverable. 49 FACTORS AND UNCERTAINTIES THAT MAY AFFECT FUTURE RESULTS The matters discussed in this Annual Report on Form 10-K include forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.

Item 7a. Quantitative and Qualitative Disclosures about Market Risk. The information required by this item can be found under the subcaption “Quantitative and Qualitative Disclosure About Market Risks” of “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7. Item 8. Financial Statements and Supplementary Data. The information called for by this item is set forth in the Consolidated Financial Statements and Schedule covered by the Report of Independent Registered Public Accounting Firm at the end of this report. Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure. This item is not applicable. Item 9A. Controls and Procedures. (a) EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES Management evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act), as of December 31, 2006, the end of the fiscal period covered by this report on Form 10-K. The Securities and Exchange Commission, or SEC, rules define the term “disclosure controls and procedures” to mean a company’s controls and other procedures that are designed to ensure that information required to be disclosed in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time period specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in its reports filed under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of the effectiveness of our disclosure controls and procedures by our management team with the participation of the Chief Executive Officer and the Chief Financial Officer, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were not effective as of such date because of the existence of a material weakness in our internal control over financial reporting related to our accounting for income taxes as described below. 50 (b) MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act). Internal control over financial reporting is designed to provide reasonable assurance that records are maintained, in reasonable detail, that assets are safeguarded and transactions are properly recorded and executed in accordance with management’s authorization. Management conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this evaluation, management concluded that the Company’s internal control over financial reporting was not effective due to the material weakness related to our accounting for income taxes as described below. A material weakness in internal control over financial reporting is a significant deficiency, or combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. Management identified the following material weakness in our internal control over financial reporting as of December 31, 2006: Our policies and procedures did not provide for effective oversight and review of our accounting for income taxes. Specifically, our policies and procedures did not include adequate management review of various income tax calculations, reconciliations and related supporting documentation to ensure that our accounting for income taxes, including accounting for income taxes associated with acquisitions made by the Company, was in accordance with generally accepted accounting principles. This control deficiency resulted in errors in the Company’s interim and annual consolidated financial statements and more than a remote likelihood that a material misstatement in the Company’s annual or interim consolidated financial statements would not be prevented or detected. Management’s assessment of the effectiveness of our internal control over financial reporting as of December 31, 2006, has been audited by KPMG LLP, an independent registered public accounting firm. Their report appears on page F-3 of this Annual Report on Form 10-K. (c) CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING There was no change in the Company’s internal control over financial reporting during the most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, internal controls over financial reporting. (d) MANAGEMENT’S REMEDIATION PLANS The Company plans to conduct significant remediation efforts throughout 2007 with the goal to remediate this material weakness prior to December 31, 2007. Although we are still discussing and finalizing the specifics of these plans, they currently include the following: • Hiring additional tax personnel and providing additional training for select tax personnel; • Redesigning and implementing new review and approval procedures and processes associated with all income tax provision workpapers and the consolidated income tax reconciliation schedules; • Increasing the oversight by our accounting department of income tax reconciliations. (e) INHERENT LIMITATIONS ON THE EFFECTIVENESS OF INTERNAL CONTROL Because of its inherent limitations, internal control over financial reporting can provide only reasonable assurance and may not prevent or detect misstatements. Further, because of changes in conditions, the effectiveness of internal control over financial reporting may vary over time. Item 9B. Other Information. None. 51 PART III Item 10.

F-10 F-1 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Shareholders Entegris, Inc.: We have audited the accompanying consolidated balance sheets of Entegris, Inc. and subsidiaries as of December 31, 2006 and 2005, and the related consolidated statements of operations, shareholders’ equity and comprehensive income (loss), and cash flows for the year ended December 31, 2006, the four-month period ended December 31, 2005, and the years ended August 27, 2005 and August 28, 2004. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Entegris, Inc. and subsidiaries as of December 31, 2006 and December 31, 2005, and the results of their operations and their cash flows for the year ended December 31, 2006, the four-month period ended December 31, 2005 and for the years ended August 27, 2005 and August 28, 2004, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Entegris, Inc.’s internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 16, 2007, expressed an unqualified opinion on management’s assessment of, and an adverse opinion on the effective operation of, internal control over financial reporting. /s/ KPMG LLP Minneapolis, Minnesota March 16, 2007 F-2 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Shareholders Entegris, Inc.: We have audited management’s assessment, included in the accompanying Management’s Report On Internal Control Over Financial Reporting (Item 9A(b)), that Entegris, Inc. did not maintain effective internal control over financial reporting as of December 31, 2006 because of the effect of the material weakness identified in management’s assessment, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Entegris, Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. A material weakness is a control deficiency, or combination of control deficiencies, that result in more than a remote likelihood that a material weakness of the annual or interim financial statements will be prevented or detected. The following material weakness has been identified and included in management’s assessment as of December 31, 2006: The Company’s policies and procedures did not provide for effective oversight and review of the accounting for income taxes. Specifically, the Company’s policies and procedures did not include adequate management review of various income tax calculations, reconciliations and related supporting documentation to ensure that the Company’s accounting for income taxes, including accounting for income taxes associated with acquisitions made by the Company, was in accordance with generally accepted accounting principles. This control deficiency resulted in errors in the Company’s interim and annual consolidated financial statements and more than a remote likelihood that a material misstatement in the Company’s annual or interim consolidated financial statements would not be prevented or detected. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Entegris, Inc. as of December 31, 2006 and 2005, and the related consolidated statements of operations, shareholders’ equity and comprehensive income (loss), and cash flows for the year ended December 31, 2006, the four-month F-3 period ended December 31, 2005 and the years ended August 27, 2005 and August 28, 2004. This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2006 consolidated financial statements, and this report does not affect our report dated March 16, 2007, which expressed an unqualified opinion on those consolidated financial statements. In our opinion, management’s assessment that Entegris, Inc. did not maintain effective internal control over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Also, in our opinion, because of the effect of the material weakness described above on the achievement of the objectives of the control criteria, Entegris, Inc. has not maintained effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). /s/ KPMG LLP Minneapolis, Minnesota March 16, 2007 F-4 ENTEGRIS, INC.

F-9 ENTEGRIS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations and Principles of Consolidation Entegris is a worldwide developer, manufacturer and supplier of materials integrity management solutions to the microelectronics industry in general and to the semiconductor and data storage markets in particular. The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. Intercompany profits, transactions and balances have been eliminated in consolidation. The Company was incorporated in Delaware in June 2005 under the name Eagle DE, Inc. (Eagle DE) as a wholly owned subsidiary of Entegris, Inc., a Minnesota corporation (Entegris Minnesota). Effective August 6, 2005, Entegris Minnesota and Mykrolis Corporation, a Delaware corporation, completed a strategic merger of equals transaction, pursuant to which they were each merged into the Company to carry on the combined businesses. Pursuant to the merger the Company’s name was changed to Entegris, Inc. The stock-for-stock transaction was accounted for under the purchase method of accounting as an acquisition of Mykrolis by the Company. Fiscal Year On December 13, 2005, the Company’s Board of Directors approved a change in fiscal year end from a 52-week or 53-week fiscal year period ending on the last Saturday of August to a fiscal year ending December 31. The Company’s new fiscal quarters consist of 13 week periods that end on Saturday. The Company’s fiscal quarters in 2006 ended on April 1, 2006, July 1, 2006, September 30, 2006 and December 31, 2006. As a result, the financial periods presented and discussed are as follows: (i) the year ended December 31, 2006 represents the twelve months ended December 31, 2006; (ii) the four-month transition period represents the four months ended December 31, 2005; (iii) the year ended August 27, 2005 represents the twelve months ended August 27, 2005; and (iv) the year ended August 28, 2004 represents the twelve months ended August 28, 2004. Basis of Presentation Certain amounts reported in previous years have been reclassified to conform to the current year’s presentation. These classifications had no effect on the amounts, total assets, net income, shareholders’ equity or cash flow from operations of the Company. Cash Flow Statement Revisions In accordance with Statement of Financial Accounting Standard (“SFAS”) No. 95, “Statement of Cash Flows,” the net cash flows from operating and investing activities reported in the Consolidated Statements of Cash Flows have been revised to separately disclose the net cash flows attributable to the operating and investing activities of discontinued operations. There were no cash flows attributable to financing activities of discontinued operations. The Company’s Consolidated Statements of Cash Flow for prior fiscal years previously reported the combined cash flows attributable to operating and investing activities of discontinued operations as a single amount. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, particularly receivables, inventories, accrued expenses and income taxes, and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Stock-based Compensation In December 2004, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standard (“SFAS”) No. 123R, Share-Based Payment. SFAS No. 123R is a revision of FASB Statement No. 123, “Accounting for Stock-Based Compensation,” and supersedes Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” and amends SFAS No. 95, “Statement of Cash Flows,” and its related implementation guidance. SFAS No. 123R focuses primarily on accounting for transactions in which an entity obtains employee services through share-based payment transactions. SFAS No. 123R requires a public entity to measure the cost of employee services received in F-10 exchange for the award of equity instruments based on the fair value of the award at the date of grant. The cost is to be recognized over the period during which an employee is required to provide services in exchange for the award. SFAS No. 123R also requires the benefit of tax deductions in excess of recognized compensation expense to be reported as a financing cash flow, rather than as an operating cash flow as prescribed under previous accounting rules. This requirement reduces net operating cash flows and increases net financing cash flows in periods subsequent to adoption. Total cash flows remain unchanged from those reported under previous accounting rules. Effective August 28, 2005, the Company adopted the provisions of SFAS No. 123R using the modified prospective method. Results of operations for prior annual periods have not been restated to reflect recognition of stock-based compensation expense. Upon adoption of SFAS No. 123R, the Company applied an estimated forfeiture rate to unvested awards. Previously, the Company recorded forfeitures as incurred. Prior to the adoption of SFAS No. 123R, the Company followed the intrinsic value method in accordance with APB 25 to account for its employee stock options and employee share purchase plan. Accordingly, no compensation expense was recognized for share purchase rights granted in connection with the issuance of stock options under the Company’s employee stock option plan or employee stock purchase plan; however, compensation expense was recognized in connection with the issuance of restricted stock awards. The adoption of SFAS No. 123R primarily resulted in a change in the Company’s method of recognizing stock-based compensation and estimating forfeitures for unvested awards. See Note 17 to the Consolidated Financial Statements for additional information on stock-based compensation. Cash, Cash Equivalents and Short-term Investments Cash and cash equivalents include cash on hand and highly liquid debt securities with original maturities of three months or less, which are valued at cost. Debt securities with original maturities greater than three months and remaining maturities of less than one year are classified and accounted for as available for sale and are recorded at fair value, and are classified as short-term investments. Inventories Inventories are stated at the lower of cost or market. Cost is determined by the first-in, first-out (FIFO) method. Property, Plant, and Equipment Property, plant and equipment are carried at cost and are depreciated principally on the straight-line method over the estimated useful lives of the assets. When assets are retired or disposed of, the cost and related accumulated depreciation are removed from the accounts, and gains or losses are recognized in the same period. Maintenance and repairs are expensed as incurred; significant additions and improvements are capitalized. Property, plant and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group of asset(s) may not be recoverable based on estimated future undiscounted cash flows. The amount of impairment, if any, is measured as the difference between the net book value and the estimated fair value of the asset(s). Investments The Company’s nonmarketable investments are accounted for under either the cost or equity method of accounting, as appropriate. All equity investments are periodically reviewed to determine if declines, if any, in fair value below cost basis are other-than-temporary. Significant and sustained decreases in quoted market prices and a series of historical and projected operating losses by investees are considered in the review. If the decline in fair value is determined to be other-than-temporary, an impairment loss is recorded and the investment written down to a new cost basis. Fair Value of Financial Instruments The carrying value of cash equivalents, short-term investments, accounts receivable, accounts payable and short-term debt approximates fair value due to the short maturity of those instruments. The fair value of long-term debt was estimated using discounted cash flows based on market interest rates for similar instruments and approximated its carrying value at December 31, 2006. Goodwill and Other Intangible Assets Goodwill is the excess of the purchase price over the fair value of net assets of acquired businesses. The Company does not amortize goodwill, but tests for impairment at least F-11 annually. Other amortizable intangible assets include, among other items, patents, unpatented and other developed technology and customer-based intangibles, and are amortized using the straight-line method over their respective estimated useful lives of 3 to 10 years. The Company reviews intangible assets for impairment if changes in circumstances or the occurrence of events suggest the remaining value is not recoverable. Derivative Financial Instruments SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, requires the Company to record derivatives as assets or liabilities on the balance sheet and to measure such instruments at fair value. Changes in fair value of derivatives are recorded each period in current results of operations or other comprehensive income, depending on whether the derivative is designated as part of a hedge transaction. The Company periodically enters into forward foreign currency contracts to reduce exposures relating to rate changes in certain foreign currencies. Certain exposures to credit losses related to counterparty nonperformance exist. However, the Company does not anticipate nonperformance by the counterparties since they are large, well-established financial institutions. None of these derivatives is accounted for as a hedge transaction under the provisions of SFAS No. 133. Accordingly, changes in the fair value of forward foreign currency contracts are recorded as a component of net income. The fair values of the Company’s derivative financial instruments are based on prices quoted by financial institutions for these instruments. The Company was a party to forward foreign currency contracts with notional amounts of $58.3 million and $12.8 million at December 31, 2006 and December 31, 2005, respectively. Foreign Currency Translation Assets and liabilities of foreign subsidiaries are translated from foreign currencies into U.S. dollars at period-end exchange rates. Income statement amounts are translated at the weighted average exchange rates for the year. Gains and losses resulting from foreign currency transactions are included in other income, net in the consolidated statements of operations. Revenue Recognition/Concentration of Risk Revenue and the related cost of sales are generally recognized upon shipment of the products. Revenue for product sales is recognized upon delivery, when title and risk of loss have been transferred to the customer; collectibility is reasonably assured, and pricing is fixed or determinable. For certain customized precision cleaning equipment sales with installation and customer acceptance provisions, which constituted less than 1% of sales, revenue is recognized upon fulfillment of such provisions. The Company provides for estimated returns and warranty obligations when the revenue is recorded. The Company sells its products throughout the world primarily to companies in the microelectronics industry. The Company performs continuing credit evaluations of its customers and generally does not require collateral. Letters of credit may be required from its customers in certain circumstances. The Company maintains an allowance for doubtful accounts which management believes is adequate to cover losses on trade receivables. Certain materials included in the Company’s products are obtained from a single source or a limited group of suppliers. Although the Company seeks to reduce dependence on those sole and limited source suppliers, the partial or complete loss of these sources could have at least a temporary adverse effect on the Company’s results of operations. Furthermore, a significant increase in the price of one or more of these components could adversely affect the Company’s results of operations. Income Taxes Deferred income taxes are provided in amounts sufficient to give effect to temporary differences between financial and tax reporting. The Company accounts for tax credits as reductions of income tax expense in the year in which such credits are allowable for tax purposes. The Company utilizes the asset and liability method for computing its deferred income taxes. Under the asset and liability method, deferred tax assets and liabilities are based on the temporary difference between the financial statement and tax basis of assets and liabilities and the enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. F-12 The Company intends to continue to reinvest its undistributed international earnings in its international operations; therefore, no U.S. tax expense has been recorded to cover the repatriation of such undistributed earnings. Comprehensive Income (Loss) Comprehensive income (loss) represents the change in shareholders’ equity resulting from other than shareholder investments and distributions. The Company’s foreign currency translation adjustments, unrealized gains and losses on marketable securities and minimum pension liability adjustments are included in accumulated other comprehensive income (loss). Comprehensive income (loss) and the components of accumulated other comprehensive income (loss) are presented in the accompanying consolidated statements of shareholders’ equity and comprehensive income (loss). Recent Accounting Pronouncements In July 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109 (FIN No. 48). FIN No. 48 is effective for the Company as of January 1, 2007. FIN No. 48 defines the threshold for recognizing the benefits of tax positions in the financial statements as “more-likely-than-not” to be sustained upon examination. The interpretation also provides guidance on the de-recognition, measurement and classification of income tax uncertainties, along with any related interest and penalties. FIN No. 48 also requires expanded disclosure at the end of each annual reporting period including a tabular reconciliation of unrecognized tax benefits. In accordance with FIN No. 48, the Company will report the difference between the net amount of assets and liabilities recognized in the statement of financial position prior to and after the application of FIN No. 48 as a cumulative effect adjustment to the January 1, 2007 balance of retained earnings. The adoption of FIN No. 48 is currently not expected to have a material effect on the Company’s consolidated financial statements. In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (SFAS No. 157). This statement provides a single definition of fair value, a framework for measuring fair value and expanded disclosures concerning fair value. Previously, different definitions of fair value were contained in various accounting pronouncements creating inconsistencies in measurement and disclosures. SFAS No. 157 applies under those previously issued pronouncements that prescribe fair value as the relevant measure of value, except SFAS No. 123(R) and related interpretations and pronouncements that require or permit measurement similar to fair value, but are not intended to measure fair value. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The Company has not yet determined the impact on its consolidated financial statements, if any, of adopting the provisions of SFAS No. 157. In September 2006, the FASB issued SFAS No. 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans—an amendment of FASB Statements No. 87, 88, 106 and 132(R) (SFAS No. 158). This statement requires balance sheet recognition of the overfunded or underfunded status of pension and postretirement benefit plans. Under SFAS No. 158, actuarial gains and losses, prior service costs or credits, and any remaining transition assets or obligations that have not been recognized under previous accounting standards must be recognized in accumulated other comprehensive income (loss), net of tax effects, until they are amortized as a component of net periodic benefit cost. In addition, the measurement date (the date at which plan assets and the benefit obligation are measured) is required to be the Company’s fiscal year end. The Company adopted the recognition provisions of SFAS No. 158 effective December 31, 2006. See Note 18 to the consolidated financial statements. The adoption of SFAS No. 158 did not have a material impact on the Company’s consolidated results of operations. In September 2006, the Securities and Exchange Commission (SEC) issued Staff Accounting Bulletin (SAB) No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements. SAB No. 108 provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement. The SEC staff believes that registrants should quantify errors using both a balance sheet and an income statement approach and evaluate whether either approach results in quantifying a misstatement that, when all relevant quantitative F-13 and qualitative factors are considered, is material. SAB No. 108 is effective as of the end of fiscal years ending after November 15, 2006. The adoption of SAB No. 108 did not have a material impact on the Company’s consolidated financial statements. (2) ACQUISITIONS AND DIVESTITURES Acquisition of Mykrolis Corporation On August 6, 2005, Entegris merged with Mykrolis Corporation (Mykrolis) in a transaction accounted for as an acquisition for a purchase price of approximately $645.0 million, which included Entegris common stock and vested share awards, as well as transaction costs. Mykrolis was a worldwide developer, manufacturer and supplier of liquid and gas delivery systems, components and consumables used to precisely measure, deliver, control and purify the process liquids, gases and chemicals that are used in the semiconductor manufacturing process. Its products were also used to manufacture a range of other products, such as flat panel displays, high purity chemicals, photoresists, solar cells, gas lasers, optical and magnetic storage devices and fiber optic cables. Mykrolis sold its products worldwide through a direct sales force and through distributors in selected regions. The acquisition was made to expand the Company’s global network, expand its product offering base and enhance the leverage of its manufacturing and administrative functions. The fair value of Entegris equity securities was derived using an average market price per share of Entegris common stock of $9.94, which was based on Entegris’ average stock price for the period two days before through two days after the terms of the acquisition were agreed to and announced on March 21, 2005, net of registration costs associated with the issued securities. Under the terms of the merger agreement, each outstanding share of Mykrolis common stock was exchanged for 1.39 shares of Entegris common stock in a tax-free transaction. Accordingly, no amount of goodwill is expected to be deductible for tax purposes. The acquisition was accounted for as a purchase business combination. Under the purchase method of accounting, the assets acquired and liabilities assumed from Mykrolis are recorded at the date of acquisition, at their respective fair values. The consolidated financial statements and reported results of operations of Entegris issued after completion of the acquisition reflect these values. The Company’s consolidated financial statements include the net assets and results of operations from August 6, 2005, the date of acquisition.

Developed technology represents the technical processes, intellectual property, and institutional understanding that were acquired from Mykrolis with respect to products, compounds and/or processes for which development had been completed. The fair value of identifiable intangible assets was determined using the “income approach” on a project-by-project basis. This method starts with a forecast of expected future net cash flows. These net cash flow projections do not anticipate any revenue or cost synergies. These cash flows are then adjusted to present value by applying an appropriate discount rate that reflects the risk factors associated with the cash flow streams, some of which are more certain than others. The valuations were based on the information that was available as of the acquisition date and the expectations and assumptions that have been deemed reasonable by the Company’s management. No assurance can be given, however, that the underlying assumptions or events associated with such assets will occur as projected. For these reasons, among others, the actual results may vary from the projected results. (d) The increase to fair value for acquired benefit plans was $1.1 million for pension benefit obligations. The fair value of the pension obligations, determined in consultation with independent actuarial specialists, includes assumptions relating to economic factors such as interest rates of high quality fixed income investments, demographic factors such as salary growth projections and other data, such as expected employee terminations. The underlying assets of the plans were measured using market rates as of the acquisition date. (e) The decrease for net assets to be sold is based on fair value less cost to sell at disposal. On September 12, 2005 the Company announced that it would divest the gas delivery (GD) product line included in the Mykrolis acquisition. The assessment and formulation of a plan to exit the GD business began in the period leading up to the date of consummation. This divestiture was completed in February 2006. The GD product line includes mass flow controllers, pressure controllers and vacuum gauges that are used by customers in manufacturing operations to measure and control process gas flow rates and to control and monitor pressure and vacuum levels during the manufacturing process. As part of the purchase accounting allocation for Mykrolis, the $13.1 million fair value of the assets of the GD business was classified as an asset held for sale. F-16 (f) Gives effect to the estimated tax effects of the acquisition. (g) In accordance with the requirements of SFAS No. 142, Goodwill and Other Intangible Assets (SFAS No.142), the goodwill associated with the merger will not be amortized. None of the goodwill is deductible for tax purposes. The goodwill recorded in connection with the acquisition is expected to be realized through the benefits of cost-saving synergies associated with the leveraging of the Company’s manufacturing and administrative functions as well as the enhancement of sales and marketing through the company’s expanded global network and product offerings. Pro Forma Results The following unaudited pro forma financial information presents the combined results of operations of the Company as if the acquisition of Mykrolis had occurred as of the beginning of the years presented. The unaudited pro forma financial information is not necessarily indicative of what the Company’s consolidated results of operations actually would have been had the acquisition occurred at the beginning of each year. In addition, the unaudited pro forma financial information does not attempt to project the future results of operations of the combined company.

The elimination of transactions between Entegris and Mykrolis, which upon completion of the merger would be considered intercompany. This reflects the elimination of inter-company sales and associated intercompany profit. Incremental amortization and depreciation expense of approximately $6.6 million and $7.3 million in 2005 and 2004, respectively, related to the estimated fair value of identifiable intangible assets and property, plant and equipment from the purchase price allocation. Identifiable intangible assets are being amortized over their estimated useful lives over a range of 3 to 9 years and property, plant and equipment is being depreciated over the estimated useful lives of the underlying assets. The pro forma data includes the results of operations for Entegris, Inc. for the twelve months ended August 27, 2005 and August 28, 2004 for 2005 and 2004, respectively, while the results of operations for Mykrolis are included for the twelve-month period ended July 2, 2005 and July 3, 2004, respectively. The above pro forma results have been reclassified to segregate the operating results of discontinued operations. The unaudited pro forma financial information above for the year ended August 28, 2004 excludes the purchase accounting impact of the incremental charge of $23.8 million reported in cost of sales for the sale of acquired inventory that was written up to fair value. F-17 Prior year acquisition In May 2004, the Company completed the acquisition of a precision parts cleaning business located in Montpellier, France in a cash transaction for total consideration of $4.5 million, of which $0.9 million was paid in 2005. The transaction was made to expand the geographic reach of Entegris’ materials integrity management services. Identifiable intangible assets and goodwill of approximately $0.8 million and $1.2 million, respectively, were recorded in connection with the transaction. The fiscal 2004 transaction was accounted for by the purchase method. Accordingly, the Company’s consolidated financial statements include the net assets and results of operations from the date of the acquisition. Divestitures and Discontinued Operations On September 12, 2005, the Company announced that it would divest its gas delivery, life science and tape and reel product lines. The gas delivery products included mass flow controllers, pressure controllers and vacuum gauges that are used by customers in manufacturing operations to measure and control process gas flow rates and to control and monitor pressure and vacuum levels during the semiconductor manufacturing process. The life sciences products included stainless steel clean in place systems for life sciences applications. Tape and reel products included the Stream™ product line, which is a packaging system designed to protect and transport microelectronic components, while enabling the high-speed automated placement of the components onto printed circuit boards used for electronics. The assets and liabilities of the life sciences product line and the assets of the tape and reel product line were sold in December 2005 for net proceeds of $0.8 million and $1.0 million, respectively. The Company closed the sale of the gas delivery assets in February 2006. After adjustments for severance, sublease payments and other closing costs, the net proceeds of the sale totaled $13.1 million. As part of the purchase accounting allocation of the acquisition of Mykrolis, the fair value of the assets of the gas delivery product line were classified as assets held for sale as of the date of the August 6, 2005 acquisition. Accordingly, the Company adjusted its purchase price allocation related to the assets of the gas delivery product line and did not recognize a gain or loss from the sale. The consolidated financial statements have been reclassified to segregate as discontinued operations the assets and liabilities, and operating results of, the product lines divested for all periods presented. The summary of operating results from discontinued operations is as follows: (In thousands) Year ended December 31, 2006 Four months ended December 31, 2005 Year ended August 27, 2005 Year ended August 28, 2004 Net sales . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $3,403 $15,473 $ 9,066 $ 9,610 Loss from discontinued operations, before income taxes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The after-tax earnings of discontinued operations in the year ended December 31, 2006 included a tax benefit of $1.6 million associated with a decrease in the company’s deferred tax asset valuation allowance resulting from the resolution of a matter with respect to the characterization of certain gains and losses. Assets of discontinued operations and other assets held for sale shown in the Consolidated Balance Sheet as of December 31, 2005 include the net assets of the gas delivery business carried at $13.6 million, and a building unrelated to the above product lines held for sale carried at $1.1 million. This building was sold in the second quarter of 2006 for net proceeds of $1.8 million, resulting in a pre-tax gain of $0.7 million which was recorded as a reduction of cost of sales. At December 31, 2006, that account included a building located in Germany held for sale carried at $2.2 million.

The Company recorded asset impairment write-offs on molds and equipment due to abandonment of approximately $1.5 million, $3.0 million, $3.3 million, and $1.3 million for the fiscal year ended December 31, 2006, the four months ended December 31, 2005, and the fiscal year ended August 27, 2005 and August 28, 2004, respectively. In the four months ended December 31, 2005, $0.5 million of the impairments were included in selling, general and administrative expenses and in the fiscal year ended August 28, 2004, $0.4 million of the impairments were included in engineering, research and development expenses; all other impairment losses are included in cost of sales. F-19 (6) INVESTMENTS Equity Investments During 2004, the Company recorded other income of $1.1 million on the sale of an aggregate 0.5 million shares of common stock of Nortem N.V. (formerly Metron Technology N.V.), a publicly traded security for total proceeds of $5.0 million. On August 16, 2004, Nortem announced that it had entered into an agreement with Applied Materials, Inc. (Applied), pursuant to which Applied would acquire the business assets of Nortem. On December 14, 2004, Nortem completed its sale to Applied of the outstanding shares of Nortem’s worldwide operating subsidiaries and substantially all of the other assets held at the Nortem level. Immediately following the closing, Nortem entered into liquidation. Subsequently, Nortem paid two liquidation distributions to shareholders of record in the amount of $4.77 per Nortem share for each of the remaining 1.1 million shares owned by the Company. Accordingly, based on the Company’s carrying value of $2.00 per share and the $5.0 million cash distribution, the Company recorded a pre-tax gain of approximately $2.9 million that was reflected as other income in the year ended August 27, 2005. In addition, as a result of the liquidation activities of Nortem, Nortem ceased to be an affiliate of the Company as of February 2005. Accordingly, the Company no longer classifies its trade receivable due from Nortem separately in its consolidated balance sheet, nor have sales after that date been categorized as sales to affiliates. Sales to Nortem under previous distribution agreements classified as sales to affiliates were $14.7 million and $32.2 million in the years ended August 27, 2005 and August 28, 2004, respectively. At December 31, 2006, the Company held equity investments totaling $7.7 million in certain privately held companies accounted for under either the cost or equity method of accounting, as appropriate.

The decrease mainly reflected adjustments to the purchase price allocation of the Mykrolis acquisition completed in August 2005. The Mykrolis purchase price had been preliminarily allocated based on estimates of the fair values of assets acquired and liabilities assumed as of August 6, 2005. The final valuation of net assets was completed in 2006.

There were no borrowings outstanding under this commitment at December 31, 2006 and December 31, 2005. Under the unsecured revolving credit agreement, the Company is prohibited from paying cash dividends. The Company is also subject to, and is in compliance with, certain financial covenants including a debt to earnings leverage ratio of funded debt to EBITDA (as defined therein) of not more than 2.25 to 1.00. In addition, the Company must maintain a calculated consolidated tangible net worth, which, as of December 31, 2006, was $294 million, while also maintaining consolidated aggregate amounts of cash and cash equivalents (which under the agreement may also include auction rate securities and variable rate demand notes classified as short-term investments) of not less than $75 million. The Company has entered into unsecured line of credit agreements, which expire at various dates, with three international commercial banks, which provide for aggregate borrowings of 250 thousand euros, 10.0 million Malaysia ringgits and 200 million Japanese yen for its foreign subsidiaries, which is equivalent to $4.8 million as of December 31, 2006. Interest rates for these facilities are based on a factor of the banks’ reference rates. Borrowings outstanding under international line of credit agreements at December 31, 2006 and December 31, 2005, were none and $2.3 million, respectively. (12) LEASE COMMITMENTS As of December 31, 2006, the Company was obligated under noncancellable operating lease agreements for certain sales offices, manufacturing, vehicle, information technology equipment and warehouse space.

F-23 (13) RESTRUCTURING COSTS On November 29, 2005, the Company announced that during 2006 it would close its manufacturing plant located in Bad Rappenau, Germany and relocate the production of products made in that facility to other existing manufacturing plants located in the United States and Asia. In addition, the Company is moving its Bad Rappenau administrative center to Dresden, Germany. In connection with these actions, the Company expects estimated charges of $7.4 million for employee severance and retention costs (generally over the employees’ required remaining term of service) and asset impairment and accelerated depreciation. Severance and retention costs, mainly classified as selling, general and administrative expense, totaled $4.4 million and $0.6 for the year ended December 31, 2006 and four months ended December 31, 2005, respectively. Other costs of $1.2 million and $1.1 million, related to fixed asset write-offs and accelerated depreciation classified in cost of sales, were also recorded in for the year ended December 31, 2006 and four months ended December 31, 2005, respectively. In addition, the Company’s facility in Bad Rappenau became available for sale during the third quarter of 2006 and is classified in other assets held for sale as of December 31, 2006 at a carrying value of $2.2 million. For the year ended December 31, 2006 and four months ended December 31, 2005, the accrued liabilities, provisions and payments associated with the employee severance and retention costs of the Bad Rappenau restructuring activity were as follows: (In thousands) Year ended December 31,2006 Four months ended December 31, 2005 Accrued liabilities at beginning of period . . . . . . . . . . . . . . . . . .

F-25 As a result of commitments made by the Company related to investment in tangible property and equipment (approximately $43 million by December 31, 2008), the establishment of a research and development center in 2006 and certain employment commitments through 2010, income from certain manufacturing activities in Malaysia is exempt from tax for years up through 2015. The income tax benefits attributable to the tax status of these subsidiaries are estimated to be $2.4 million (2 cents per diluted share), $0.4 million (zero cents per diluted share), $1.0 million (1 cent per diluted share), and $0.7 million (1 cent per diluted share) for the year ended December 31, 2006, four months ended December 31, 2005 and years ended August 27, 2005 and August 28, 2004, respectively. $2.8 million, $0.1 million, $0.8 million and $2.0 million was added to additional paid-in capital in accordance with FAS No. 123R or APB No. 25 reflecting tax differences relating to employee stock option and restricted stock award transactions for the year ended December 31, 2006, four months ended December 31, 2005 and years ended August 27, 2005 and August 28, 2004, respectively.

No U.S. tax has been provided on such earnings. If they were remitted to the Company, applicable U.S. federal and foreign withholding taxes would be partially offset by available foreign tax credits. At December 31, 2006, the Company had federal net operating loss carryforwards of approximately $37.6 million which begin to expire in 2020, state operating loss carryforwards of approximately $ 2.8 million, which begin to expire in 2009, foreign tax credit carryforwards of approximately $2.8 million which begin to expire in 2010, alternative minimum tax credit carryforwards of approximately $0.9 million and research tax credit carryforwards of approximately $ 2.3 million which begin to expire in 2009. F-26 The Company established a valuation allowance of $2.2 million during the four months ended December 31, 2005 with respect to capital loss carryovers, of which $1.5 million reversed in 2006. Realization of the remaining deferred tax assets is dependent on generating sufficient future taxable income and on the future reversal of taxable temporary differences. Although realization is not assured, based on projected earnings, the Company believes it is more likely than not that the benefit of these deferred assets will be realized. (17) SHAREHOLDERS’ EQUITY Share Repurchase Program On August 21, 2006, the Company’s Board of Directors authorized a share repurchase program of up to $150 million over the succeeding 12 to 18 months. In connection with the share repurchase program the Company entered into an Accelerated Share Repurchase Agreement (ASRA) and a Collared Accelerated Share Repurchase Agreement (CASRA) with Goldman, Sachs & Co. (GS) on August 30, 2006. Under the ASRA, which was effective as of August 30, 2006, the Company acquired 4.7 million shares of common stock on September 5, 2006 from GS for $50.0 million, which was paid on September 5, 2006. The transaction was accounted for as a share retirement with common stock, paid-in capital and retained earnings reduced by $47 thousand, $28.2 million, and $21.7 million, respectively. Under the CASRA, the Company paid $50.0 million for a prepaid forward contract, which was effective August 30, 2006, to repurchase the Company’s common stock. The Company received deliveries of common stock of 3.0 million shares and 1.2 million shares on September 5, 2006 and October 6, 2006, respectively. The transaction was accounted for as a share retirement with common stock, paid-in capital and retained earnings reduced by $42 thousand, $25.2 million, and $19.8 million, respectively. $5.0 million of the $50.0 million payment is reflected as a prepaid forward contract for share repurchase in shareholders’ equity, which will be credited as the Company receives additional shares under the CASRA. Under both the ASRA and the CASRA, GS may repurchase an equivalent number of shares in the open market through September 4, 2007. At that date, the Company’s price under the ASRA will be adjusted up or down based on the volume-weighted average price of the stock during this period. Such adjustment may be settled in cash or stock at the Company’s discretion. The Company may receive additional shares pursuant to the CASRA, depending on movements in the market price of the Company’s common stock. The Company financed the ASRA and CASRA with its available cash equivalents and short-term investments. Share-based Compensation Expense Effective August 28, 2005, the Company adopted Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment, (SFAS 123(R)) which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors including employee stock options and employee stock purchases related to the Employee Stock Purchase Plan (employee stock purchases) to be based on estimated fair values. SFAS 123(R) supersedes the Company’s previous accounting under Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB 25). In March 2005, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 107 (SAB 107) relating to SFAS 123(R). The Company has applied the provisions of SAB 107 in its adoption of SFAS 123(R). The Company adopted SFAS 123(R) using the modified prospective transition method, which requires the application of the accounting standard as of August 28, 2005. In accordance with the modified prospective transition method, the Company’s Consolidated Financial Statements for prior periods were not restated to reflect, and did not include, the impact of SFAS 123(R). Share-based compensation expense recorded under SFAS 123(R) for the year ended December 31, 2006 and four months ended December 31, 2005 was $14.8 million and $11.1 million, respectively. Share-based compensation expense of $5.5 million and $1.2 million, respectively, for the years ended August 27, 2005 and August 28, 2004 was mainly related to restricted stock grants that the Company had been recognizing under previous accounting standards. F-27 SFAS 123(R) requires companies to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in the Company’s Consolidated Statement of Operations. Prior to the adoption of SFAS 123(R), the Company accounted for share-based awards to employees and directors using the intrinsic value method in accordance with APB 25 as allowed under Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation (SFAS 123). Under the intrinsic value method, no share-based compensation expense had been recognized in the Company’s Consolidated Statement of Operations, other than as related to restricted stock grants, because the exercise price of the Company’s stock options granted to employees and directors equaled the fair market value of the underlying stock at the date of grant. Share-based compensation expense recognized for periods after the adoption of SFAS 123(R) is based on the value of the portion of share-based payment awards that is ultimately expected to vest during the period. Share- based compensation expense recognized in the Company’s Consolidated Statement of Operations for the year ended December 31, 2006 and four months ended December 31, 2005 includes compensation expense for share- based payment awards granted prior to, but not yet vested as of August 27, 2005 based on the grant date fair value estimated in accordance with the pro forma provisions of SFAS 123. Share-based payment awards in the form of restricted stock awards for 1.1 million shares were granted to employees during the year ended December 31, 2006, with no shares granted during the four months ended December 31, 2005. Share-based payment awards in the form of stock awards subject to performance conditions for up to 0.9 million shares were also granted to certain employees during the year ended December 31, 2006, with no performance shares granted during the four months ended December 31, 2005. Compensation expense is based on the grant date fair value estimated in accordance with the provisions of SFAS 123(R). In conjunction with the adoption of SFAS 123(R), the Company changed its method of attributing the value of share-based compensation to expense from the accelerated multiple-option approach to the straight-line single option method. Compensation expense for all share-based payment awards granted on or prior to August 27, 2005 will continue to be recognized using the accelerated multiple-option approach, while compensation expense for all share-based payment awards granted subsequent to August 27, 2005 will be recognized using the straight- line single-option method. Because share-based compensation expense recognized in the Consolidated Statement of Operations for the year ended December 31, 2006 and four months ended December 31, 2005 is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. SFAS 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. In the Company’s pro forma information required under SFAS 123 for the periods through August 27, 2005, the Company accounted for forfeitures as they occurred. There were stock option awards of 1.1 million shares and 1.0 million shares, respectively, in the years ended August 27, 2005 and August 28, 2004. Restricted stock awards of 1.9 million and 0.2 million shares were made to employees in the years ended August 27, 2005 and August 28, 2004. Prior to August 28, 2005, the Company used the Black-Scholes option-pricing model (Black-Scholes model) for the Company’s pro forma information required under SFAS 123. The Company’s determination of fair value of share-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to the Company’s expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors and forfeitures. On November 10, 2005, the Financial Accounting Standards Board (FASB) issued FASB Staff Position No. FAS 123(R)- 3, Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards (FSP 123(R)-3). An entity could take up to one year from the effective date of FSP 123(R)-3 to evaluate its available transition alternatives and make its one-time election. The Company adopted the alternative transition method provided in the FASB Staff Position for calculating the tax effects of share-based compensation pursuant to SFAS 123(R). The alternative transition method includes simplified methods to establish the beginning balance F-28 of the additional paid-in capital pool (APIC pool) related to the tax effects of employee share-based compensation, and to determine the subsequent impact on the APIC pool and Consolidated Statements of Cash Flows of the tax effects of employee share-based compensation awards that are outstanding upon adoption of SFAS 123(R). Employee Stock Purchase Plan The Company has the Entegris, Inc. Employee Stock Purchase Plan (ESPP). A total of 4.0 million common shares are reserved for issuance under the ESPP. The ESPP allows employees to elect, at six-month intervals, to contribute up to 10% of their compensation, subject to certain limitations, to purchase shares of common stock at the lower of 85% of the fair market value on the first day or last day of each six-month period. The Company treats the ESPP as a compensatory plan under SFAS 123(R). As of December 31, 2006, 1.1 million shares had been issued under the ESPP. At December 31, 2006, 2.9 million shares remained available for issuance under the ESPP. Employees purchased 0.2 million, none, 0.2 million and 0.2 million, shares at a weighted-average price of $8.06, none, $8.34, and $10.34 during the year ended December 31, 2006, four months ended December 31, 2005 and years ended August 27, 2005 and August 24, 2004, respectively. Employee Stock Option Plans As of December 31, 2006, the Company had five stock incentive plans: the Entegris, Inc. 1999 Long-Term Incentive and Stock Option Plan (the 1999 Plan), the Entegris, Inc. Outside Directors’ Option Plan (the Directors’ Plan) and three former Mykrolis stock option plans assumed by the Company on August 10, 2005: The 2001 Equity Incentive Plan (the 2001 Plan), the 2003 Employment Inducement and Acquisition Stock Option Plan (the Employment Inducement Plan) and the 2001 Non-Employee Director Stock Option Plan (the 2001 Directors Plan). At present, the Company intends to issue new common shares upon the exercise of stock options under each of these plans. The plans are described in more detail below. 1999 Plan: The 1999 Plan provides for the issuance of share-based awards to selected employees, directors, and other persons (including both individuals and entities) who provide services to the Company or its affiliates. Under the 1999 Plan, the Board of Directors determines the number of shares for which each option is granted, the rate at which each option is exercisable and whether restrictions will be imposed on the shares subject to the awards. The term of options issued under the 1999 Plan has been ten years, generally exercisable ratably in 25% increments over the 48 months following grant, with exercise prices equal to 100% of the fair market value of the Company’s common stock on the date of grant. The Directors’ Plan and the 2001 Directors Plan: The Directors’ Plan provides for the grant to each outside director of an option to purchase 15,000 shares on the date the individual becomes a director and for the annual grant to each outside director, at the choice of the Directors’ Plan administrator (defined as the Board of Directors or a committee of the Board), of either an option to purchase 9,000 shares, or a restricted stock award of up to 3,000 shares. Options are exercisable six months subsequent to the date of grant. Under the Directors’ Plan, the term of options shall be ten years and the exercise price for shares shall not be less than 100% of the fair market value of the common stock on the date of grant of such option. The 2001 Directors Plan provides for the grant to each newly elected eligible director of options to purchase 15,000 shares of common stock on the date of his or her first election and for the annual grant of options to purchase 10,000 shares of common stock for each subsequent year of service as a director. The exercise price of the stock options may not be less than the fair market value of the stock at the date of grant. On August 10, 2005 the Company’s Board of Directors determined that the equity compensation paid to non-employee directors would be an aggregate of 10,000 shares of restricted stock per annum, inclusive of the amounts specified in the above described plans. 2001 Plan: The 2001 Plan provides for the issuance of share-based awards to selected employees, directors, and other persons (including both individuals and entities) who provide services to the Company or its affiliates. The 2001 Plan has a term of ten years. Under the 2001 Plan, the Board of Directors determines the term of each option, option price, number of shares for which each option is granted, whether restrictions will be imposed on the shares subject to options, and the rate at which each option is exercisable. The exercise price for incentive F-29 stock options may not be less than the fair market value per share of the underlying common stock on the date granted (110% of fair market value in the case of holders of more than 10% of the voting stock of the Company). The 2001 Plan contains an “evergreen” provision, which increases the number of shares in the pool of options available for grant annually by 1% of the number of shares of common stock outstanding on the date of the Annual Meeting of Stockholders or such lesser amount determined by the Board of Directors. Under NASDAQ rules new grants and awards under the 2001 Plan may only be made to employees and directors of the Company who were employees or directors of Mykrolis prior to the merger or who were hired by the Company subsequent to the merger. Employment Inducement Plan: The Employment Inducement Plan is a non-shareholder approved plan that provides for the issuance of stock options and other share-based awards to newly-hired employees and to employees of companies acquired by the Company. The Employment Inducement Plan has a term of ten years. Options granted under the Employment Inducement Plan have a maximum term of ten years and an exercise price equal to the fair market value of the Company’s common stock on the date of grant. The Board of Directors determines other terms of option grants including, number of shares, restrictions and the vesting period. The number of reserved shares under the Employment Inducement Plan automatically increases annually by 0.25% of the number of shares of common stock outstanding on the date of the Annual Meeting of Stockholders unless otherwise determined by the Board of Directors. Millipore Plan In addition to the Company’s plans, certain employees of the Company who were employees of Mykrolis were granted stock options under a predecessor’s share-based compensation plan. The Millipore 1999 Stock Incentive Plan (the Millipore Plan) provided for the issuance of stock options and restricted stock to key employees as incentive compensation. The exercise price of a stock option was equal to the fair market value of Millipore’s common stock on the date the option was granted and its term was generally ten years and vested over four years. Options granted to the Company’s employees under the Millipore Plan in the past were converted into options to acquire Mykrolis common stock pursuant to the spin-off of Mykrolis by Millipore, and then were converted into options to acquire the Company’s common stock pursuant to the merger with Mykrolis. General Option Information Option activity for the 1999 Plan and the Directors’ Plan for the year ended December 31, 2006, four months ended December 31, 2005 and years ended August 27, 2005 and August 28, 2004 are summarized as follows: Year ended December 31, 2006 Four months ended December 31, 2005 Year ended August 27, 2005 Year ended August 28, 2004 Weighted average exercise price Number of shares Weighted average exercise price Number of shares Weighted average exercise price Number of shares Weighted average exercise price Number of shares 8,501 — (1,925) (193) $ 7.35 — 5.56 11.35 8,826 — (231) (94) $ 7.30 — 4.23 10.43 8,268 1,125 (415) (152) $7.05 8.39 4.49 9.23 8,080 1,012 (657) (167) $ 6.28 12.32 5.27 8.77 (Shares in thousands) Options outstanding, beginning of period . . . . . . . . . . . .

For all plans, the total pretax intrinsic value of stock options exercised during the year ended December 31, 2006 and four months ended December 31, 2005 was $14.2 million and $4.0 million, respectively. The aggregate intrinsic value in the preceding tables represent the total pretax intrinsic value, based on the Company’s closing stock price of $10.82 at December 31, 2006, which theoretically could have been received by the option holders had all option holders exercised their options as of that date was $35.6 million and $34.4 million, respectively for options outstanding and options exercisable. The total number of in-the-money options exercisable as of December 31, 2006 was 10.2 million. During the year ended December 31, 2006 and year ended August 27, 2005, certain existing stock option grants were modified in connection with the execution of various severance and separation agreements. Under the agreements, the terms of unvested and vested stock option grants were modified with no future service required by the affected individuals. Accordingly, under the measurement principles of SFAS No. 123(R ) and APB No. 25, incremental share-based compensation expense of $0.4 million and $1.0 million, respectively, was recognized for the value of the modified stock option grants at the date of the agreements’ execution. During the year ended December 31, 2006, four months ended December 31, 2005 and years ended August 27, 2005 and August 28, 2004, the Company received cash from the exercise of stock options totaling $18.5 million, $3.8 million, $3.4 million and $2.8 million, respectively. During the year ended December 31, 2006, four months ended December 31, 2005 and years ended August 27, 2005 and August 28, 2004, the Company received cash of $1.5 million, none, $1.5 million and $1.6 million, respectively, in employee contributions to the Entegris, Inc. Employee Stock Purchase Plan. There was no excess tax benefit recorded for the tax deductions related to stock options and restricted stock awards during the year ended December 31, 2006 or the four months ended December 31, 2006. Restricted Stock Awards Restricted stock awards are awards of common stock that are subject to restrictions on transfer and to a risk of forfeiture if the awardee leaves the Company’s employ prior to the lapse of the restrictions. The value of such stock is determined using the market price on the grant date. Compensation expense is recorded over the applicable restricted stock vesting periods. In conjunction with the adoption of SFAS 123(R), the Company changed its method of attributing the value of share-based compensation to expense from the accelerated multiple-option approach to the straight-line single option method. Accordingly, compensation expense for restricted stock awards granted on or prior to August 27, 2005 are recorded using the accelerated multiple-option approach, while compensation expense for restricted stock awards granted subsequent to August 27, 2005 are recognized using the straight-line single-option method. A summary of the Company’s restricted stock activity for the year ended December 31, 2006, four months ended December 31, 2005 and years ended August 27, 2005 and August 28, 2004 is presented in the following table: (Shares in thousands) Year ended December 31, 2006 Four months ended December 31, 2005 Year ended August 27, 2005 Year ended August 28, 2004 Weighted average grant date fair value Number of shares Weighted average grant date fair value Number of shares Weighted average grant date fair value Number of shares Weighted average grant date fair value Number of shares Unvested, beginning of period . . . . . . . . . . . . . . . . . . .

As of December 31, 2006 total compensation cost related to nonvested stock options and restricted stock awards not yet recognized was $12.2 million that is expected to be recognized over the next 14.6 months on a weighted- average basis. These figures exclude restricted stock awards for which performance criteria have yet to be determined and, accordingly, grant dates for those awards have not been established. During the year ended December 31, 2006, Entegris, Inc. awarded performance stock to be issued upon the achievement of performance conditions (Performance Shares) under the Company’s stock incentive plans to certain officers and other key employees. Up to 0.9 million shares, 25% of which are available each of the next four years, will become vested if, and to the extent that, financial performance criteria for fiscal years 2006 through 2009 are achieved. The number of performance shares earned in a given year may vary based on the level of achievement of financial performance objectives for that year. If the Company’s performance for a year fails to achieve the specified performance threshold, then the performance shares allocated to that year are forfeited. Each annual tranche will have its own service period beginning at the date (the grant date) at which the Board of Directors establishes the annual performance targets for the applicable year. Once earned, Performance Shares are fully vested with no restrictions. Compensation expense to be recorded in connection with the Performance Shares will be based on the grant date fair value of the Company’s common stock. Awards of Performance Shares are expensed over the service period based on an evaluation of the probability of achieving the performance objectives. Certain unvested restricted shares of Mykrolis common stock issued in connection with restricted stock awards made prior to the merger with the Company were exchanged for unvested restricted shares of the Company’s common stock, with the number of shares adjusted for the exchange ratio of 1.39. Accordingly, 0.3 million restricted Mykrolis shares were exchanged for 0.4 million restricted shares of the Company’s common stock. The intrinsic value of $2.5 million associated with the unvested restricted stock was recorded as deferred compensation as part of the purchase price allocation for the Mykrolis acquisition. This balance is being charged to earnings over the remaining vesting periods that extend to 2009. Valuation and Expense Information under SFAS 123(R) The following table summarizes share-based compensation expense related to employee stock options, restricted stock awards and grants under the employee stock purchase plan under SFAS 123(R) for the year ended December 31, 2006 and four months ended December 31, 2005 that was allocated as follows: (In thousands) Year ended December 31, 2006 Four months ended December 31, 2005 Cost of sales . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

After consideration of various alternatives, the Committee approved the accelerated and full vesting of all unvested outstanding employee stock options with exercise prices above $9.21 issued prior to October 1, `2004. The effect of the vesting acceleration was the recognition of incremental additional stock-based employee compensation of approximately $4.8 million in the first quarter of the year ended August 28, 2005 in the Company’s pro forma disclosure above. This previously deferred stock-based employee compensation expense amount would otherwise in part have been recognized in the Company’s consolidated statements of operations in future periods after the adoption of SFAS No. 123R on August 28, 2005. The fair value of options granted and the option component of the employee purchase plan shares were estimated at the date of grant using the Black-Scholes option pricing model and the following assumptions: Option plans Year ended August 27, 2005 Year ended August 28, 2004 Expected dividend yield . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Shareholder Rights Plan On July 27, 2005, the Company’s Board of Directors adopted a shareholder rights plan (the “Rights Plan”) pursuant to which Entegris declared a dividend on August 8, 2005 to its shareholders of record on that date of one preferred share purchase right (a “Right”) for each share of Entegris common stock owned on August 8, 2005. Each Right entitles the holder to purchase one-hundredth of a share of a series of preferred stock at an exercise price of $50, subject to adjustment as provided in the Rights Plan. The Rights Plan is designed to protect Entegris’ shareholders from attempts by others to acquire Entegris on terms or by using tactics that could deny all shareholders the opportunity to realize the full value of their investment. The Rights are attached to the shares of the Company’s common stock until certain triggering events specified in the Rights Agreement occur, including, unless approved by the Company’s board of directors, an acquisition by a person or group of specified levels of beneficial ownership of Entegris common stock or a tender offer for Entegris common stock. Upon the occurrence of any of these triggering events, the Rights authorize the holders to purchase shares of the Company’s common stock at the then-current exercise price having a value equal to twice the exercise price. The Rights are redeemable by the Company for $0.01 and will expire on August 8, 2015. One of the events which will trigger the Rights is the acquisition, or commencement of a tender offer, by a person (an Acquiring Person, as defined in the shareholder rights plan), other than Entegris or any of its subsidiaries or employee benefit plans, of 15% or more of the outstanding shares of the Company’s common stock. An Acquiring Person may not exercise a Right. (18) BENEFIT PLANS 401(k) Plan The Company maintains the Entegris, Inc. 401(k) Savings and Profit Sharing Plan (the 401(k) Plan) that qualifies as a deferred salary arrangement under Section 401(k) of the Internal Revenue Code. Under the Plan, eligible employees may defer a portion of their pretax wages, up to the Internal Revenue Service annual contribution limit. Entegris matches 100% of employees’ contributions on the first 3% of eligible wages and 50% of employees’ contributions on the next 2% of eligible wages, or a maximum match of 4% of the employee’s eligible wages. In addition to the matching contribution, the Company’s board of directors may, at its discretion, declare a profit sharing contribution as a percentage of eligible wages based on the company’s worldwide operating results. The employer profit sharing and matching contribution expense under the Plans was $5.8 million, $0.7 million, $4.6 million and $3.9 million in the fiscal year ended December 31, 2006, the four months ended December 31, 2005, and the fiscal years ended August 27, 2005 and August 28, 2004, respectively. Supplemental Savings and Retirement Plan The Company has Supplemental Savings and Retirement Plan (the “Supplemental Plan”) that was assumed in the Mykrolis acquisition. Under the Supplemental Plan, certain senior executives are allowed certain salary deferral benefits that would otherwise be lost by reason of restrictions imposed by the Internal Revenue Code limiting the amount of compensation which may be deferred under tax-qualified plans. A liability of $3.2 million and $2.6 million at December 31, 2006 and December 31, 2005, respectively, related to these rights is included in the consolidated balance sheets under the caption “Other liabilities”. The Company recorded expense of $0.5 million and $0.3 million in the year ended December 31, 2006 and the four months ended December 31, 2005, respectively. The Company recorded no expense in connection with the Supplemental Plan in the years ended August 27, 2005 and August 28, 2004. Defined Benefit Plans. The Company assumed the obligations under defined benefit pension plans in its merger with Myrkolis on August 6, 2005. The employees of the Company’s subsidiaries in Japan and Taiwan are covered in defined benefit pension plans. The Company uses a December 31 measurement date for its pension plans. F-35 Effective December 31, 2006, the Company adopted SFAS No. 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans. Under SFAS No. 158, the Company is required to recognize the overfunded or underfunded status of its defined benefit pension plans as an asset or liability in its consolidated balance sheets and to recognize changes in that funded status in the year in which the changes occur through comprehensive income. SFAS No. 158 also requires the measurement of the funded status of a plan as of the date of its year-end consolidated balance sheet. The Company’s existing policy was to measure the funded status of it plans as of the balance sheet date; accordingly, the new measurement date requirements of SFAS No. 158 will have no impact.

F-37 Plan Assets At December 31, 2006, the majority of the Company’s pension plan assets are invested in a Japanese insurance company’s guaranteed-return fixed income securities. There is interest rate risk associated with the valuation of these investments. The long-term rate of return on Japanese pension plan assets was developed through an analysis of historical returns and the fund’s current guaranteed return rate. Estimates of future returns are based on a continuation of the existing guaranteed rate of return. The remaining portion of the Company’s plan assets are deposited in Central Trust of China in the form of cash, where Central Trust of China is the assigned funding vehicle for the statutory retirement benefit. Cash Flows The Company expects to contribute $0.4 million to its defined benefit pension plans during fiscal 2007.

The effect of the inclusion of stock options and unvested restricted common stock for the four- month period ended December 31, 2005 would have been anti-dilutive.

In the fiscal year ended December 31, 2006, the four months ended December 31, 2005, and the fiscal years ended August 27, 2005 and August 28, 2004, net sales to the Company’s top ten customers accounted for approximately 28%, 32%, 37%, and 36%, respectively, of the Company’s net sales. F-39 (21) COMMITMENTS AND CONTINGENT LIABILITIES The following discussion provides information regarding certain litigation to which the Company was a party that were pending as of December 31, 2006. As previously disclosed, on March 3, 2003 the Company’s predecessor, Mykrolis Corporation, filed a lawsuit against Pall Corporation in the United States District Court for the District of Massachusetts alleging infringement of two of the Company’s U.S. patents by certain fluid separation systems and related assemblies used in photolithography applications manufactured and sold by the defendant. The Company’s lawsuit also sought a preliminary injunction preventing the defendant from the manufacture, use, sale, offer for sale or importation into the U.S. of any infringing product. On April 30, 2004, the Court issued a preliminary injunction against Pall Corporation and ordered Pall to immediately stop making, using, selling, or offering to sell within the U.S., or importing into the U.S., its PhotoKleen EZD-2 Filter Assembly products or “any colorable imitation” of those products. On January 18, 2005, the Court issued an order holding Pall Corporation in contempt of court for the violation of the preliminary injunction and ordering Pall to disgorge all profits earned from the sale of its PhotoKleen EZD-2 Filter Assembly products and colorable imitations thereof from the date the preliminary injunction was issued through January 12, 2005. In addition, Pall was also ordered to reimburse Mykrolis for certain of its attorney’s fees associated with the contempt and related proceedings. The Court’s order also dissolved the preliminary injunction, effective January 12, 2005, based on certain prior art cited by Pall which it alleged raised questions as to the validity of the patents in suit. On February 17, 2005, the Company filed notice of appeal to the U.S. Circuit Court of Appeals for the Federal Circuit appealing the portion of the Court’s order that dissolved the preliminary injunction and Pall filed a notice of appeal to that court with respect to the finding of contempt and the award of attorneys’ fees; these cross appeals are pending. On April 6, 2006 the Company filed a lawsuit against Pall Corporation in the United States District Court for the District of Massachusetts alleging infringement of the Company’s newly issued U.S. patent No. 7,021,667 by certain filter assembly products used in photolithography applications that are manufactured and sold by the defendant. The Company’s lawsuit also seeks a preliminary injunction preventing the defendant from the manufacture, use, sale, offer for sale or importation into the U.S. of the infringing products. On October 23, 2006 the Company’s motion for preliminary injunction was argued before the court; a decision on this motion is pending. On August 23, 2006 the Company filed a lawsuit against Pall Corporation in the United States District Court for the District of Massachusetts alleging infringement of the Company’s newly issued U.S. patent No. 7,037,4247 by certain fluid separation modules and related separation apparatus, including the product known as the EZD-3 Filter assembly, used in photolithography applications that are manufactured and sold by the defendant. It is believed that the EZD-3 Filter assembly was introduced into the market by the defendant in response to the action brought by the Company in March of 2003 as described above. This case is currently in the preliminary stages. As previously disclosed, on December 16, 2005 Pall Corporation filed suit against the Company in U.S. District Court for the Eastern District of New York alleging patent infringement. Specifically, the suit alleges infringement of two of plaintiff’s patents by certain of the Company’s filtration products. Both products and their predecessor products have been on the market for a number of years and one is covered by patents held by the Company. The Company intends to vigorously defend this suit and believes that it will ultimately prevail. This case is currently in the discovery stage. In addition, from time to time, the Company is a party to various legal proceedings arising in the ordinary course of our business.
