General

Rockwood is a global developer, manufacturer and marketer of technologically advanced, high value-added specialty chemicals and advanced materials used for industrial and commercial purposes. Rockwood was incorporated in Delaware in September 2000 in connection with an acquisition of certain specialty chemical businesses from Laporte plc (“Laporte”) on November 20, 2000 (the “KKR Acquisition”). On July 31, 2004, we acquired the specialty chemicals and advanced materials businesses of Dynamit Nobel (the “Dynamit Nobel Acquisition”). See Note 3, “Acquisitions” for further detail. Through this acquisition, we have created a further diversified portfolio of distinct specialty chemicals and advanced materials businesses, combining two companies with similar service-driven cultures focused on high margins; expertise in inorganic chemistry; stable profitability; growth platforms; and proven management teams. In addition, we believe the Dynamit Nobel Acquisition bolsters our leading competitive positions by enhancing our ability to develop innovative products and solutions for our customers, expanding our technological knowledge and further reducing our exposure to any particular raw material or end-use market. Rockwood is controlled by affiliates of Kohlberg Kravis Roberts & Co. L.P. (“KKR”).

Our products consist primarily of inorganic chemicals and solutions and engineered materials. They are often customized to meet the complex needs of our customers and to enhance the value and performance of their end products by improving performance, providing essential product attributes, lowering costs or making them more environmentally friendly. We generally compete in niche markets in a wide range of end-use markets, including construction, life sciences (including pharmaceutical and medical markets), electronics and telecommunications, metal treatment and general industrial and consumer products markets. No single end-use market accounted for more than 18% of our 2005 net sales.

We have a number of high growth businesses, which are complemented by a diverse portfolio of businesses that historically have generated stable revenues. Our margins, strong cash flow generation, capital discipline and ongoing productivity improvements provide us with a platform to capitalize on market growth opportunities.

We operate globally, manufacturing our products in over 100 manufacturing facilities in 25 countries and selling our products and providing our services to more than 60,000 customers, including some of the world’s preeminent companies. We believe our products are generally critical to our customers’ products’ performance, but account for a small percentage of the total cost of their products. No single customer accounted for more than 2% of our 2005 net sales. For a geographic description of the origin of our net sales and location of our long-lived assets, see Note 4, “Segment Information.”

On August 22, 2005, the Company completed an initial public offering (“IPO”) of 23,469,387 shares of its common stock, which included 3,061,224 shares issued and sold as a result of the underwriters’ exercise of the over-allotment option. See Note 2, “Initial Public Offering,” for further detail.

Following the Dynamit Nobel Acquisition, we operate our business through the following seven business segments: (1) Performance Additives; (2) Specialty Compounds; (3) Electronics; (4) Specialty Chemicals; (5) Titanium Dioxide Pigments; (6) Advanced Ceramics; and (7) Groupe Novasep. The following table sets forth for each of our seven segments net sales of such segment, and the percentage of our net sales for the year ended December 31, 2005, as well as our principal products and our principal end-use markets. For financial information about each segment, see Note 4, “Segment Information.”

Diverse Customer and End-Use Market Base. We operate a diverse portfolio of distinct specialty chemicals and advanced materials businesses. We have more than 60,000 customers worldwide that cover a wide variety of industries and geographic areas. Of our 2005 net sales, 51% were shipments to Europe, 33% to North America and 16% to the rest of the world. No customer accounted for more than 2% of such net sales, and our top ten customers represented only approximately 11% of such net sales. Our largest end-use market represented approximately 18% of such net sales. The following chart provides a breakdown of our 2005 net sales by end-use markets:

5

Within these end-use markets, there is further diversification by sector, product and region. For example, within the construction end-use market, our Performance Additives segment companies provide materials for new construction as well as companies that focus on remodeling and renovation. In addition, we serve construction materials clients in both the residential and commercial sectors located in North America, Europe and Asia. Within the life sciences end-use market, we serve a number of sectors, including: the medical applications sector through our Specialty Compounds and Advanced Ceramics segments; the pharmaceutical intermediates and active ingredients sector through our Groupe Novasep segment; and the pharmaceutical ingredients sector through our Specialty Chemicals segment.

Operating Segments

The following describes each of our operating segments, as well as the principal products or principal divisions within each segment.

Performance Additives (22% of 2005 net sales)

Our Performance Additives segment consists of business lines, which develop and manufacture a range of specialty chemicals that are used in industrial and consumer products and processes to enhance performance or create unique characteristics. This segment manufactures and markets products that are based on a focused research and development effort and a strong technology base. Our Performance Additives segment generated net sales of $680.7 million, $630.9 million, and $477.3 million, on an actual basis, for the years ended December 31, 2005, 2004 and 2003, respectively. See Note 4, “Segment Information,” for additional financial information regarding our Performance Additives segment.

Color Pigments and Services

Our Color Pigments and Services business line is a global producer of synthetic iron oxide and other inorganic pigments in a wide range of yellow, red, orange, blue, black or blended shades, and serves the construction, paints and coatings, plastics, and specialty application markets with powder, granular and liquid grades. Color Pigments and Services focuses on developing and manufacturing high value-added inorganic pigments. The business also offers a number of unique pigment dispensing systems. Color Pigments and Services generates sales from construction applications, which include colorings for concrete products such as paving stones, bricks, concrete blocks, roofing tiles, ready mix, stucco and mortar; for paints and coatings as well as colorants for plastics, paper and rubber; and for specialty applications including security inks, toners for printers and copiers, catalysts and cosmetics.

Our Color Pigments and Services business line has been driven by product innovation, our brand names and our customer and technical service, including customer-specific color blending. We expect this segment to benefit from the growing trend towards the use of color in concrete paving stones and other home remodeling fueled in part by increased exposure at “do-it-yourself” home centers.

An important component of Color Pigments and Services’ product innovation has been our granulated pigment, Granufin, which, when used in conjunction with our Granumat dispensing system, offers significant advantages to customers over traditional pigment systems in the coloring of manufactured concrete products, such as ease of handling and consistency in coloring. We believe that Granumat is the leading granulated pigment dispensing system worldwide and is a result of Color Pigments and Services’ research and development focus on process and delivery systems for its products. In addition, in May 2000 we commercialized our Chameleon dispensing system, which electronically controls the delivery of pigments into ready-mix concrete when used with our liquid pigment product line.

6

In March 2003, we acquired the assets of Southern Color Company, Inc. and its affiliates, which expanded our Color Pigments and Services product portfolio into the brick and decorative market segments and provided us with access to the packaged mortar tolling business. In addition, in March 2003, Color Pigments and Services purchased a majority interest in a manufacturer of iron oxide pigments in China. The joint venture manufactures and dry blends pigments and provides us with a continuing source of pigments, as well as an important platform to expand Color Pigments and Services’ commercial activities inside the Asia Pacific region. In June 2003, Color Pigments and Services entered into an agreement pursuant to which an affiliate of W.R. Grace & Co., which sells admixtures and fibers, distributes our liquid pigments and Chameleon dispensing systems to ready-mix and precast producers in the concrete industry. We believe our combined efforts will provide ready mix and precast customers with added value in the form of colored ready mix concrete.

In September 2004, we acquired the assets of the pigments and dispersions business of Johnson Matthey Plc., which included facilities located in Kidsgrove and Sudbury, United Kingdom, and Braeside, Australia for approximately $50.0 million. The pigments and dispersions business produces transparent iron oxide pigments and dispersions, color concentrates and complex inorganic color pigments used in the surface and wood coatings, plastics, building materials and print ink markets. In addition, during 2004 we acquired the assets of a producer of liquid pigments, which included a facility in King of Prussia, Pennsylvania.

Principal Products

Construction Color Pigments and Services. We develop and manufacture principally iron oxide pigments for manufacturers of construction products for use in the coloring of concrete products, including paving stones, bricks, concrete blocks, roofing tiles, stucco and mortar. Color Pigments and Services’ major U.S. brand is Davis Colors and its key products include Granufin/Granumat, Hydrotint, Mix-Ready and Chameleon. Granufin is a unique, dry, micro-granulated pigment that combines the flow characteristics of a liquid with the storage and handling advantages of a powder. The Granumat dispensing system offers a variety of configurations and features designed to accommodate the varying requirements and budgets of concrete product manufacturers. Granufin pigments and the Granumat system improve product handling and color consistency for our customers. The granulation technology used in Granufin is patented until 2007 in the United States. Our Chameleon system, which works in combination with our liquid pigments, automatically weighs, blends and conveys colors into a ready-mix truck using a standard personal computer and custom-developed Windows-based software.

Paints, Coatings and Colorants. We also develop and manufacture colored pigments for the paints, coatings, plastics, paper and rubber end-use markets including the brands Ferroxide, Trans-oxide and Colourplex. We produce a wide variety of pigments for these markets that include synthetic iron oxides, corrosion inhibitor pigments, complex inorganic color pigments and process natural pigments such as burnt umbers and siennas. The largest application for these products is colorant used in architectural, industrial and special purpose paints and coatings. Color, ease of dispersion and chemical stability are the primary characteristics of our products, which can be used in a wide variety of both solvent and water-borne systems. We believe that a number of Color Pigments and Services’ products are considered industry standards in the markets in which we compete, such as our Mapico yellow pigment for architectural and industrial applications and our heat stable tans, which can tolerate applications requiring high temperature processing, such as plastic compounding and roofing granules.

Specialties. Our iron oxide pigments are also used in a wide variety of specialty applications such as toner for large printers and copiers, security inks used to print bank notes, catalysts for styrene production and cosmetics. Each of these markets requires specialized pigments with unique properties, which are often as important as the coloring characteristics. For example, printer toners require specific magnetic properties whereas pigments used in cosmetics require color and purity.

Competition

We believe that there are a significant number of producers of iron oxide pigments across the globe at both the pigment synthesis and finishing levels with whom we compete. We believe these producers include Lanxess Corporation, Elementis plc, Cathay Pigments, Interstar, Yipin Pigments as well as other producers in the United States, Europe, Japan and China. Competition in this growing segment is based on customer service, product attributes, such as product form and quality, and price. Product quality is critical in the higher end of the business on which Color Pigments and Services focuses as inconsistent product quality can have an adverse impact on the color consistency of the end-product.

7

Customers

Color Pigments and Services’ key customers include Engelhard Corporation, Oldcastle (CRH plc), Pavestone Company, The Sherwin-Williams Company, Degussa, Unilock Ltd. and Xerox Corporation, each of which has been our customer for at least ten years. Color Pigments and Services’ customer base is highly fragmented.

Timber Treatment Chemicals

Our Timber Treatment Chemicals business line is a manufacturer of wood protection products primarily in North America. Wood protection products enhance the performance of wood by increasing its longevity through protection from decay and fungal or insect attack. Our specialty timber chemicals also add water repellency, fire retardancy and other properties to wood products. Timber Treatment Chemicals’ products include wood protection products based on our alkaline copper quaternary, or ACQ technology, which was awarded the Environmental Protection Agency (“EPA”) Presidential Green Chemistry Challenge Award in 2002, and chromated copper arsenate, or CCA. Other products include Clearwood, our wood protection product for wood windows and doors, as well as a range of specialty additives with fire retardant, water repellent or moldicide properties. Applications include wood protection products used for decking, fencing, playground equipment, garden furniture, house construction materials, utility poles, and other wood constructions.

Timber Treatment Chemicals also manufactures inorganic chemicals such as nitrates and chlorides for various industrial applications, including chemicals that are added to concrete as curing accelerants and corrosion inhibitors, chemicals that are used for odor control in water treatment, galvanizing fluxes, micronutrients, pesticides, and catalysts used in the manufacture of textile resins.

Many of our Timber Treatment products are registered pesticides and subject to extensive regulation. In February 2002, the EPA announced a voluntary decision by CCA manufacturers, including our subsidiary, to amend their registrations for CCA to limit use of CCA-treated lumber in most residential settings. In the culmination of that process, in March 2003, the EPA amended the registrations for CCA prohibiting CCA treatment of wood, effective December 31, 2003, for use in most residential settings, including play structures, decks, picnic tables, landscaping timbers, residential fencing, patios, walkways and boardwalks. Similar initiatives were enacted in Canada by the Pest Management Regulatory Agency, which imposed similar limitations on the use of CCA-treated wood. The EPA is currently conducting a risk assessment of CCA-treated wood and results are expected in June 2006. In addition, in June 2001, special interest groups petitioned the Consumer Products Safety Commission, to ban and recall all CCA-treated wood in playground equipment and refund consumers the cost of the CCA-treated wood playground equipment that they purchased. In November 2003, the Consumer Products Safety Commission denied the petition. The use of ACQ has increased following the industry-wide voluntary transition to non-arsenic chrome-based wood protection products discussed above.

Likewise, in Japan, the use of arsenic-based chemicals, such as those used in the manufacture of CCA wood protection products, is restricted through legislation limiting the levels of arsenic allowed in rainwater runoff from outdoor wood product storage areas. Due in part to the effect of this legislation, we have been able to attain a significant portion of the Japanese timber treatment chemicals market through our ACQ product line. Various types of restrictive legislation, which would further affect the ability to use arsenic-based chemicals are currently being proposed in various jurisdictions in the United States, Canada and Australia. In European Union markets, restrictions were enacted in mid-2004.

We believe that Timber Treatment Chemicals is a leading provider in North America of new generation alternative timber treatment chemicals, such as ACQ, which does not contain chrome, arsenic or any other chemicals classified as “hazardous” by the EPA. We developed this technology to produce ACQ pursuant to a license agreement with Domtar Inc. and through the acquisition of the Kemwood business from Kemira OY. We have further developed this technology and created our own proprietary line of ACQ products under the brand names Preserve and Preserve Plus. As a result, in February 2001, we signed a licensing agreement with Osmose, Inc., another major producer of timber treatment chemicals, to license our proprietary ACQ technology to Osmose. Our ACQ technology is patent protected in the United States through mid-2007.

In addition, Timber Treatment Chemicals provides a broad range of technical expertise and services to its customers. In particular, Timber Treatment Chemicals works closely with its customers to assist them in reducing the total cost of their manufacturing process, by supplying timber treatment chemicals as well as treatment equipment, along with technical support.

Principal Products

We develop and manufacture a broad range of wood protection products, fire retardant and specialty chemicals for use in residential and industrial wood applications. In addition, we provide treatment equipment, which facilitates the handling and treatment of wood and chemicals and we provide comprehensive technical support services to our customers. Timber Treatment Chemicals’ key brands include Preserve, Preserve Plus, Ultrawood, SupaTimber, D-Blaze and Clearwood.

8

We also develop and manufacture inorganic metallic chemicals for certain specialty markets. These include zinc chloride-based products, other chlorides, and a range of nitrates and other chemicals. Some of these products are manufactured using by-products from other large chemical companies.

Competition

We believe that Timber Treatment Chemicals was one of the leading manufacturers of wood protection products in North America in 2005, along with Arch Chemicals, Inc. and Osmose, Inc. BASF Group, Kurt Obermeier GmbH & Co. KG and Weyl GmbH are other competitors, particularly in Europe. Competition for wood protection products is mainly based on price, customer support services, innovative technology and product range. In the inorganic chemicals market, we operate in niche areas, and therefore have few overall competitors. Competition in the inorganic chemicals market is mainly based on quality, customer support services and price.

Customers

Timber Treatment Chemicals sells its products primarily to wood processors who pressure-treat wood. Major customers include Georgia Pacific, Aljoma Lumber, Inc., BB&S Treated Lumber of New England, Coos Bay Lumber Company, Culpeper Wood Preservers, Inc., Koshii Preserving Co. Ltd., Jeld-Wen, Inc., and Sunbelt Forest Products Corporation. Customers of our inorganic chemicals product line include Degussa AG, Rohm and Haas Company, Nalco Company and W.R. Grace & Co. Most of these companies have been our customers for at least ten years.

Clay-based Additives

Our Clay-based Additives business line is a developer and manufacturer of specialty clay-based rheological additives. These additives are used in a wide variety of products and applications to modify viscosity, thickness and flow characteristics, keep solids in suspension, maintain levels of coloration with a lower amount of pigment, and collect suspended solids into larger particles. End-products in which these additives are used include industrial and architectural coatings, oilfield drilling fluids and carbonless copy paper. The principal end-uses for Clay-based Additives’ products are paints, inks and paper-making, household care products, oilfield fluids and other end-uses.

During the last several years, this business line has developed a number of new value-added products and applications. One of Clay-based Additives’ recently developed applications is the use of our Laponite synthetic clay as a retention aid in the paper-making process. In addition, we are currently developing new products, including anti-static coatings for paper and variants of Laponite to replace current types of thickeners in personal care products. Other products recently introduced by Clay-based Additives include Garamite, a cost-effective and easy-to-use thickener which provides low volatile organic compounds capability compared to traditional additives used in the manufacture of fiberglass composites; and Cloisite, used in the manufacture of nanocomposite plastics, which are specially engineered composite materials exhibiting superior mechanical, barrier and fire resistant properties compared to traditional plastics and which result in lighter plastic end products. In 2001, our Clay-based Additives business working with General Motors introduced the first commercial exterior automotive application of a new lightweight nanocomposite material based on Cloisite nanoclay on the step assist of the GMC Safari and Chevrolet AstroVan. Although sales of these nanocomposite materials were minimal in 2004 and 2005, we continue to explore additional applications for this product with GM and other strategic partners.

In December 2005, we completed an acquisition of the rheological additives and carbonless developers businesses of Sud Chemie AG, which included the Tixogel organoclays, Optiflo associative thickeners and Optigel activated clay product lines, as well as production facilities in Mooseburg, Bavaria, Germany and Louisville, Kentucky. We also purchased Sud Chemie’s Copisil clay product line, which is used in the manufacture of carbonless paper. This acquisition complements our existing businesses and allows us to better serve our customers with a broader product line, enhanced technical resources and increased production capability. See Note 3, “Acquisitions,” for further detail.

Principal Products

Coatings and Inks. We offer a comprehensive line of additives which modify the viscosity, flow and suspension properties of coatings and inks, including Claytone for the manufacture of special purpose coatings, such as bridge, marine and maintenance paints, and architectural coatings, and Laponite for the manufacture of automotive coatings. Our Garamite additives are used in the manufacture of high solids, low volatile organic compounds epoxy coatings for industrial applications.

Paper-Making. We serve the paper industry with a product line that includes bentonite retention aids, which are used in the paper-making process to reduce fiber losses and aid in water drainage from the sheet, and an additive, which provides fade-resistant color for carbonless copy paper. We also produce a form of Laponite which is used in the production of clear, flexible and moisture-resistant films and coatings with conductive, anti-static and anti-sticking properties, that are used in the manufacture of specialty photographic and anti-static papers, ink jet papers and anti-static packaging.

In addition, Laponite also has functional properties that improve the performance of a wide range of consumer products, such as personal care products, creams, lotions, cosmetics and hard surface household cleaning products for the kitchen and bathroom.

Oilfield. We offer a line of Claytone organoclays, which are a type of specially treated clays, for use in diesel and synthetic oilfield drilling fluids, which help to control viscosity and flow properties. These additives also help to suspend the cuttings in the fluid, so that they can be expelled from the well efficiently. We recently introduced a Garamite additive for use in deep well drilling that requires higher performance.

Other. We developed the Cloisite range of clays for the manufacture of nanocomposite plastics. Although Cloisite has not yet been released for large-scale commercial sale, we have entered into a joint development agreement in the United States with General Motors Corporation in connection with our efforts to develop nanoclays for automotive components, such as external trim and facia. In January 2004, General Motors adopted this technology for the body side molding on the 2004 Chevrolet Impala. Cloisite clays are also being evaluated in a wide range of rubber-based formulations for industrial applications. In addition, our Garamite range of clays is used in the manufacture of fiberglass composites.

Specialty Compounds (7% of 2005 net sales)

Our Specialty Compounds segment develops and manufactures thermoplastic materials possessing specialized characteristics, such as fire and smoke retardance, reduced weight or barrier properties, which are tailored to the specific needs of each intended end-product. These products are grouped into six key end-product areas: wire and cable, consumer performance products, medical applications, automotive components, regulated packaging and footwear. Our Specialty Compounds segment had net sales of $237.5 million, $200.4 million and $176.4 million, on an actual basis, for the years ended December 31, 2005, 2004 and 2003, respectively. See Note 4, “Segment Information,” for additional financial information regarding our Specialty Compounds segment.

Our Specialty Compounds segment focuses on sales of high margin products and operates as a global specialty performance plastic compounding business. We developed and commercialized SmokeGuard, our specialty compound for use in high-end data and video communication wire and cable, which must meet stringent fire retardant and low smoke generation standards. We also developed a compound for beverage closure seals and caps. This compound prevents ozone from attacking the seal and does not affect the taste of water and carbonated beverages, therefore significantly increasing the shelf life of these beverages. We also focus on thermoplastic elastomer, or TPE, compounds in our consumer performance and automotive products areas. In addition to our product offerings, we provide strong, comprehensive customer service and technical expertise by developing innovative products to satisfy our customers’ unique needs.

We intend to invest in next generation plastic compounding technologies. For example, in 2003, Specialty Compounds entered into a joint development agreement with E.I. duPont de Nemours and Company to create, manufacture and commercialize new Smokeguard® compounds based on Teflon® technologies to further raise the safety and performance standards for a variety of wire and cable compounds. Specialty Compounds is also working closely with our Clay-Additives business to create a patented composite material that exhibits superior flame retardancy for wire and cable jacketing and sheathing.

Principal Products

Wire and Cable Compounds. We develop and manufacture low-smoke vinyl alloys, such as SmokeGuard, which are used in high-end data and video communication, fiber optic and fire alarm wire and cable; halogen-free plastics, such as Sentra, which are used in industrial, aerospace, shipboard or oil rig cables as well as in communication cables; and a variety of TPE compounds, such as Garaflex, which are used in flexible cords, tray cables, booster cables, welding cables and automotive wiring. We believe that there is significant growth potential for the wire and cable product line in Europe as a result of the evolution of a common market standard with higher specifications for wire and cable compounds. Unlike in North America, European wire and cable standards dictating certain safety specifications such as fire and smoke resistance have not yet been enacted.

Fine Chemicals

Our Fine Chemicals business line consists of our lithium, special metals, metal sulfides and rubber chemicals product lines. We believe that our Fine Chemicals business line is the leading global producer of basic and specialty lithium compounds and chemicals and advanced metal-based specialty chemicals.

Fine Chemicals develops and manufactures a broad range of basic lithium compounds, including lithium carbonate, lithium hydroxide, lithium nitrate, lithium chloride, and value added lithium reagents, including butyllithium and lithium aluminum hydride. Lithium is a key component in products and processes used in a variety of applications and industries, which range from lithium batteries, high performance greases, thermoplastic elastomers for car tires, rubber soles and plastic bottles to intermediates in the pharmaceutical industry. In our Fine Chemicals business, we operate our lithium business along the following four business divisions reflecting its core end-markets: (1) Specialities/Life Sciences; (2) Base Chemicals; (3) Elastomers; and (4) Electronics.

Lithium carbonate can be resold or used as a primary raw material for more specialized forms of lithium-based materials. We have developed an integrated, low cost manufacturing capability based on a range of proprietary technologies and advanced equipment, including brine processing technology and aqueous chemistry for a broad variety of lithium salts. In addition to developing and supplying lithium compounds, we provide technical service, including training of customers’ employees, for handling reactive lithium products. We also offer our customers recycling services for lithium containing by-products resulting from synthesis with organolithium products, lithium metal and other reagents. Product quality is critical in the life sciences, elastomers and electronics industries. We believe that these services and our ability to handle highly reactive compounds in large quantities serve to build customer loyalty. In Lithium, we plan to continue to focus on the development of new products and applications. Over the last 20 years, the use of lithium products has grown substantially in a variety of applications, such as life sciences and electronics, largely as a result of innovation and product development. Currently, we are in the process of developing lithium compounds for several near- to medium-term, new and potentially high growth products for applications such as fuel cells, batteries for electric vehicles or lithium-aluminum alloys.

Fine Chemicals also develops and manufactures advanced metal-based specialty chemicals along two business divisions based on its principal product groups: (1) Metal Sulfides, which develops and manufactures natural and synthetic metal sulfides used in brake pads and clutch facings and cutting and grinding wheels and (2) Special Metals, which develops and manufactures cesium products for the chemical and pharmaceutical industries and zirconium, barium and titanium products for various applications including airbags. Fine Chemicals is the only commercial producer of certain metal compounds, which are used for X-ray image intensifiers and displays for digital X-ray technology. Fine Chemicals also sells accelerators for the rubber industry.

In our metal-based specialty chemicals business, we are well positioned in the field of metal sulfides and special metals, offering a broad range of products and fully integrated production processes, as a result of which we are a single source supplier for many of our customers. Fine Chemicals benefits from a long-standing expertise in handling, processing and developing new specialty metal products. Fluctuations in purity grades of the products can lead to significant losses in customers’ production processes. Fine Chemicals has a reputation among its customers for consistently producing highly customized, quality products. We have had strong sales growth over the past three fiscal years in our metal-based specialty chemicals business, driven by the shift towards synthetic sulfides in brake pads. Currently, we are a major supplier of synthetic metal sulfides for use in brake pads. In addition, we hold several key patents, which, we believe, gives us a competitive advantage in the fast growing synthetic metal sulfides market. In order to further strengthen our competitive position in the metal-based specialty chemicals market, we are focused on the production of new variations of synthetic metal sulfides, and new cesium products for organic synthesis. We also continually monitor our customers’ industries for potential new applications for our products and often achieve a sole supplier position by being the first to offer our products to potential new customers. In addition, we plan to expand our business by penetrating growth areas such as the United States and Asia.

We believe that demand for synthetic metal sulfides will increase further in the future as a result of the continuing substitution of asbestos-based friction linings, transition from naturally occurring sulfides to synthetic sulfides worldwide and the transition from drum to disk brakes in Asia and the Americas. We also believe that the market for cesium compounds will grow as a result of new applications being developed in the chemicals industry, the pharmaceutical industry, the defense industry and for use as catalysts. As a result of our competitive strengths as a supplier of cesium products for established markets, we believe we are well positioned to take advantage of this market trend.

Our Titanium Dioxide Pigments segment, which we acquired in the Dynamit Nobel Acquisition and operates under the Sachtleben brand name, is a leading producer of high quality chemical products with a unique range of small inorganic particles that add significant value to customers’ products and reduce the cost of customers’ production processes. Titanium Dioxide Pigments comprises three business lines: (1) Titanium Dioxide; (2) Functional Additives; and (3) Water Chemistry. Our Titanium Dioxide Pigments segment generated net sales of $430.5 million for the year ended December 31, 2005. Actual sales for the five months ended December 31, 2004 were $175.7 million. This segment generated net sales of $422.0 million on a pro forma basis for the year ended December 31, 2004, or 14% of our 2004 pro forma sales. Prior to the Dynamit Nobel Acquisition, the Titanium Dioxide Pigments segment generated net sales of $381.8 million for the year ended December 31, 2003. See Note 4, “Segment Information,” for additional financial information regarding our Titanium Dioxide Pigments segment.

Titanium Dioxide

Our Titanium Dioxide business line is a leading producer of specialty grade titanium dioxide (“TiO2”), serving a wide variety of customers in the synthetic fibers, plastics, paints, coatings, life sciences, cosmetics, pharmaceuticals and paper industries. TiO2 is a fine white powder that derives its value from its unparalleled whitening strength and opacifying ability, which is commonly referred to as hiding power. Our Titanium Dioxide business line’s principal products include TiO2 in anatase grade, TiO2 in rutile grade and titanium specialties. This business line also provides recycling services for sulfuric waste acid.

There are two ways of producing TiO2: the sulfate process and the chloride process. The chloride process permits production of only rutile TiO2 and is primarily suited for large volume production of standard TiO2 grades. The sulfate process is capable of producing both the rutile and anatase grade of TiO2. Approximately 58% of the globally installed TiO2 capacity uses the chloride process with the remaining using the sulfate process. Unlike rutile grades, anatase grades can only be made through the sulfate process. We employ the sulfate process for TiO2 production and thus, the output from approximately 58% of the globally installed TiO2 production capacity does not compete with our anatase products.

We believe that we have a competitive advantage in fiber anatase production and special sophisticated anatase applications based on our strong technological capabilities, long-term customer relationships and extensive test runs with regular monitoring of product and process parameters. Although it represents a negligible part of the fiber material cost, TiO2 application know-how and a longstanding application track record of homogeneous anatase crystals, both of which avoid production interruptions and excessive wear or breakdown of our customers’ equipment are critical to our customers. For over thirty years, we have worked closely with fiber producers on the optimization of their product and processes and as a result we have built up a significant wealth of customer-problem solution know-how. We intend to grow our Titanium Dioxide business line by focusing the rutile business on selected markets and applications and further developing our titanium specialties business. We expect this segment to benefit from sales of newly introduced nano-particle titanium dioxide pigments that are used to provide ultraviolet light protection for plastics and coatings.

Principal Products

TiO2 in Anatase Grade. We develop and manufacture high quality anatase TiO2 pigments. These pigments are sold primarily to the global synthetic fiber industry, as well as paper, food and pharmaceutical industries. Our anatase pigments, sold under the brand name Hombitan®, are the leading global selling TiO2 product for applications in the synthetic fiber industry.

TiO2 in Rutile Grade. We develop and manufacture rutile TiO2 pigments, which are mainly used in special applications such as selected coatings, paints, plastics and laminated paper production processes. In this product area, we are geographically focused on the European market. Rutile-based TiO2 pigments generally possess performance characteristics different from anatase-based pigments. Rutile-based pigments significantly improve the weatherability and durability of polymer products by providing protection against yellowing and preventing embrittlement of the material. Our rutile grades are state of the art products and are used in applications with high technical requirements.

Titanium Specialties. Our titanium specialties products primarily include “nano-particles”, which are exceptionally fine-particled, transparent and easy-to-use pigment formulations that are used across a large and diverse range of applications in small volumes. For example, the specialty grade TiO2 products are used as UV-absorbers in sun protection cosmetics. In addition, the new nano-particles form the basis for innovative wood-protection products and innovative color variations, by the paints and coatings industry. Other uses include catalysts, gas cleansing, photocatalysts and intermediates for special ceramics.

Recycling Services. We operate a waste acid recycling plant in Europe in our production facility in Duisburg, Germany. The sulfuric waste acid, which results from the production of TiO2, is recycled and used in the production process. This service is also offered to other TiO2 manufacturers in Europe, and we have a long-term contract with one of our competitors to provide this service.

Zinc-based Additives. We believe we are also a leading producer of pure zinc sulfide pigments, mainly used in glass fiber reinforced plastic parts and coatings and a leading supplier of Lithopone, a white zinc sulfide pigment, which is used in plastics and coatings. Lithopone is manufactured by our Huali Sachtleben joint venture in Guangzhou, China.

Competition

Key competitors for barium-based additives include Solvay S.A., Gruppo Chimico Dalton S.p.A., Sakai Chemical Industry Co., Ltd. and Chinese barium-producers. Key competitors for zinc-based additives include Chinese lithopone producers. Competition in the functional additives market is primarily based on application know-how, brand recognition, product quality and, to a certain extent, price.

Customers

Functional Additives’ customers include duPont de Nemours, Ampacet Corporation, BASF Group, Akzo Nobel Coatings and A. Schulman Plastics.

Water Chemistry

We believe that our Water Chemistry business line is a leading manufacturer of polyaluminium chloride, or PAC, and polyaluminium nitrate-based flocculants. Flocculants are added to water to improve its purity before, during and after its use in industrial, commercial and municipal applications. PAC flocculants are widely used in public, industrial and swimming pool water treatment and as a process agent in the paper industry.

We believe we have achieved a strong market position in Europe due to our comprehensive customer service arrangements, well-established brand names, competitive cost structure and innovative products. Customers in this market increasingly prefer full service offers, which include supply of water treatment chemicals together with services. Given this market trend, we believe that our ability to provide full services will help us maintain our market position. We also believe that demand for PAC flocculants will increase as a result of increased demand from the paper industry and moderate growth in public water treatment.

19

Competition

We believe that our Water Chemistry business line competes in a €190.0 million niche market for inorganic flocculants in Europe. The relevant market is characterized by production overcapacity and is geographically constrained to an approximately 300 mile radius around the production plant because the delivered product contains 80% to 90% water. Key competitors of this business line include Kemira, Feralco, TotalFina Elf and Israel Chemical Ltd./Giulini. Competition in the water chemistry market is primarily based on customer service, brand recognition and location.

Customers

Water Chemistry’s customers include Sappi Limited, Akzo Nobel, Brenntag AG, LEIPA Georg Leinfelder GmbH, and Stora Enso oyj.

Advanced Ceramics (12% of 2005 net sales)

Our Advanced Ceramics segment was acquired in the Dynamit Nobel Acquisition and operates under the CeramTec brand name. We believe it is a leading global producer of high-performance advanced ceramics materials and products. Advanced Ceramics serves four principal end-markets: (1) medical; (2) electronics; (3) industrial; and (4) automotive, with strong market positions in various niche markets such as medical products, cutting tools and mechanical applications. Our Advanced Ceramics segment generated net sales of $369.6 million for the year ended December 31, 2005. Actual net sales for the five month period ended December 31, 2004 were $146.3 million. This segment generated net sales on a pro forma basis of $349.5 million or 12% of our 2004 pro forma net sales for the year ended December 31, 2004. Prior to the Dynamit Nobel Acquisition, the Advanced Ceramics segment generated net sales of $286.0 million for the year ended December 31, 2003. See Note 4, “Segment Information,” for additional financial information regarding our Advanced Ceramics segment.

The global ceramics market comprises products and components based on inorganic, non-metallic, microcrystalline materials that are manufactured at high temperatures. The global ceramics market can be divided into traditional ceramics, such as bricks, tiles and white ware, and high-performance ceramics, which are ceramic materials and products optimized for special purposes. High performance ceramics have superior physical, electrical, chemical or biological properties as compared to traditional ceramics and competing materials, like metals or plastics. Accordingly, they have increasingly replaced plastics and metals as key engineering materials. We compete in the high-performance ceramics segment of the market, offering a wide range of high-performance ceramics products from sealing discs for sanitary fittings to ceramic components for hip joint prostheses. These products serve the market’s needs for materials that are light, strong, corrosion-resistant and capable of performing in high-temperature environments.

High-performance ceramics materials include ceramic powders, ceramic additives, structural ceramics and functional ceramics. Ceramic powders and ceramic additives are inputs to the manufacturing processes of structural and functional ceramics. Structural ceramics, also called engineering ceramics, take advantage of the mechanical properties such as hardness and wear-resistance to produce load-bearing or engineered components. Due to their resistance to corrosion and heat properties, structural ceramics are also used to perform under special chemical conditions or at high temperatures. We believe that we are one of the leading suppliers in the structural ceramics market. Functional ceramics, also referred to as electronic ceramics, focus on the unique electrical and magnetic properties of ceramics. Ceramic applications in electronic components, such as integrated circuit packages, capacitors and transformers, account for the majority of today’s high-performance ceramic materials. We believe that increasing demand for electronic components will continue to offer significant growth opportunities for high-performance ceramics, such as piezo ceramics. As a leading supplier of electronic ceramics materials, we believe we are well positioned to take advantage of these growth opportunities.

We believe that we have achieved success in the Advanced Ceramics segment as a result of our focus on selected segments of the high-performance ceramics market and our close customer relationships. Almost all of Advanced Ceramics’ products are made to order, taking into account specific customer requirements. In many cases, our engineers work in close cooperation with our customers during the design and development phase of new products to ensure highest quality and customer satisfaction. Through its extensive experience, Advanced Ceramics has gained detailed expertise and know-how in the applications areas it is active in.

Principal Products

Medical. We currently serve the medical applications market with two product groups: ceramic components for hip joint prostheses, such as ball heads and inserts; and ceramic glove formers for high-quality latex gloves. The ceramic components for hip joint prostheses are supplied to orthopedic implant manufacturers in the United States and Europe. Besides their high wear-resistance and good friction behavior, high-performance ceramics are biologically inert, making them one of the few materials that are durable and stable enough to withstand the corrosive effects of bodily fluids. As a result, high-performance ceramics are increasingly becoming more common for medical applications, such as for repair and replacement of hips, knees and other human body parts.

We expect the global market for hip implants to grow by approximately 8% per year over the next ten years, with the largest portion of the growth captured by the emerging markets in Asia, Eastern Europe and South America. We believe that ceramic-on-ceramic hip implants benefit from additional substitution effects as young people and more active elderly people are better suited to use ceramic implants, given their numerous attractive properties. Currently, the penetration rate for ceramic-on-ceramic hip-implants in Europe is significantly higher than in North America because the first FDA approval for ceramic-on-ceramic hip joint prostheses systems was granted only in 2003. However, given the relative superior performance and positive early acceptance levels in the United States, we expect the market for ceramic-on-ceramic hip joint prostheses systems to grow significantly in future years. We believe we are well positioned to take advantage of the growing market as we are currently the only manufacturer of ceramic-on-ceramic hip implant components used in FDA-approved hip joint prostheses systems in the United States to date. Given the difficulties and time involved in obtaining an FDA approval, we believe that we will be the sole supplier in the intermediate term. We also enjoy strong relationships with the largest U.S. and European orthopedics implant manufacturers. In order to expand capacity and complement our existing medical production facility in Plochingen, Germany, we have built a new factory at our site in Marktredwitz, Germany. This factory exclusively produces medical ceramics and allows us to serve the volumes required by the growing global market. We are also expanding our focus to possible new applications in knee joint and intervertebral disc replacements.

20

Electronics. We develop and manufacture substrates, electrical resistor cores and ceramic tapes as carriers for electronic circuits. Substrates are ceramic plates with electrical, thermal and mechanical properties that serve as carriers in electronic applications. These highly specialized products are used in a wide range of industries, such as automotive, consumer electronics, aeronautics and telecommunications industries. The demand for these products is driven, in large part, by the activity levels of the semiconductor market. We believe that the recovery of the semiconductor market, as well as a positive substitution effect for ceramic applications, will increase the demand for our products.

Cutting Tools. We develop and manufacture products used in cutting tools, tools and tooling systems. Ceramic material properties such as high melting points, excellent hardness and good wear resistance make ceramics an excellent high-speed cutting tool material. We enjoy a strong market position as a supplier of ceramic cutting tools, tools and tooling systems for high speed processing in the automotive, metalworking and mechanical engineering industries, with automotive OEMs being our main customers. The longer life and faster cutting speeds possible with ceramic tools allow customers to save costs by increasing their throughput and reducing the downtimes for replacing the cutting tools.

Mechanical Applications and Systems. We also develop and manufacture high performance ceramic components that are used in mechanical applications and systems. Key product groups in mechanical systems include cutting blades, drawing and forming tools, drawing cones and capstans, guide elements, precision parts, preforms and friction discs. Mechanical systems include products used in the sanitary fittings and automotive supplier industries in areas where fluids are pumped, compressed or stirred such as bushings, face seal rings, pump components and valve shims and discs. We primarily supply the general industrial machinery, metalworking, automotive and textile industries with a large number of products customized to the customer requirements.

Our customers are currently located mainly in Germany and other parts of Europe. However, we plan to expand our geographic reach. For example, we opened a new plant in China and plan to grow over the next five years by further penetrating the rapidly growing Asian market.

Other products. We also produce various products in other smaller niche markets. Some of these products are used for applications in certain niche markets with limited growth potential, such as electrical/thermal and ceramic metal connections. Other products, such as piezo ceramic components, are used for applications in certain niche markets with growth potential the next few years, primarily in the automotive sector.

Competition

Advanced Ceramics’ key competitors are Kyocera Corporation, CoorsTek, Inc., Saint Gobain, The Morgan Crucible Company plc and NGK Ceramics Europe S.A. However, each of these competitors has either a different geographical focus or product strategy with respect to small niche applications. Competition in the high performance ceramics market is primarily based on product quality, product specifications and customer service.

Customers

Advanced Ceramics’ key customers include Robert Bosch GmbH, Stryker Corporation, EPCOS AG, Texas Instruments Incorporated, Siemens AG, De Puy Orthodics, MC and Vishay Europe GmbH.

Groupe Novasep (12% of 2005 net sales)

We acquired our Groupe Novasep (previously known as Custom Synthesis) segment in the Dynamit Nobel Acquisition. On December 31, 2004, we completed a combination of the three business lines of this segment that were acquired from Dynamit Nobel (Dynamit Nobel Special Chemistry, Finorga and Rohner) with Groupe Novasep SAS (which consisted of four businesses: Novasep, Applexion, Orelis and Seripharm). Groupe Novasep specializes in innovative production of active pharmaceutical ingredients from biotechnological or chemical processes, focuses on developing new purification solutions and processes and the design, installation and on site qualification of these innovative purification processes and specializes in large-scale chromatography, continuous chromatography processes (VARICOL®), ion exchange and membranes.

21

As a result of the combination, we own approximately 79% of the combined company and Groupe Novasep SAS’ management owns the remaining 21%. We believe this combination strengthens this segment by joining together Groupe Novasep SAS proprietary separation technologies with our capabilities of developing and manufacturing advanced intermediates and active ingredients for the pharmaceutical and performance chemical industries. We believe the capabilities of new Groupe Novasep will enhance our ability to meet our customers’ demands for higher purity levels, cost efficient solutions, strict regulatory and operational controls, and shorter times to market.

As a result of the combination, our Groupe Novasep segment consists of two divisions: (1) Novasep Synthesis; and (2) Novasep Process, each of which has a specific technology focus. These two divisions serve customers across the entire life cycle of a pharmaceutical product. Our Novasep Synthesis business line focuses on the custom manufacturing of complex molecules through multi-step synthesis and is comprised of four units:

•                  Dynamit Nobel Special Chemistry, which specializes in scale-up and commercial production of hazardous chemistry with special expertise in azide chemistry;

•                  Finorga, which focuses on chiral technologies, such as asymmetric synthesis and multi-column chromatography, or MCC;

•                  Rohner, which offers a range of multi-step synthesis products, including transition metal catalysis, or TMC (In March 2006, we sold Rohner AG, see Note 17, “Impairment Charges,” for further details); and

•                  Seripharm, which specializes in the production of high-potent active pharmaceutical ingredients.

Our Novasep Process business line specializes in the development and optimization of purification processes, as well as the design, installation and on-site qualification of the customized purification systems in the pharmaceuticals and bio-chemical industries. This business line is comprised of the following units:

•                  Novasep, which offers the development, design and installation of purification equipment and systems for molecules; and

•                  Applexion and Orelis, which offer separation solutions to purify molecules from natural biological sources.

Our Groupe Novasep segment generated net sales of $379.1 million for the year ended December 31, 2005. Actual net sales for the five months ended December 31, 2004 were $101.0 million. This segment generated net sales on a pro forma basis of $338.6 million or 12% of our 2004 pro forma net sales for the year ended December 31, 2004. Prior to the Dynamit Nobel Acquisition and not including Groupe Novasep, the Custom Synthesis segment generated net sales of $268.4 million for the year ended December 31, 2003. See Note 4, “Segment Information,” to our audited consolidated financial statements for additional financial information regarding our Groupe Novasep segment.

Novasep Synthesis

Modern drugs require multiple steps of production to create the end product. These steps often involve highly complex chemical reactions. While pharmaceutical companies have the technical capability to carry out certain of these manufacturing steps in-house, they also use custom synthesis manufacturers to provide additional production capacity as well as creative chemical solutions to reduce the production cost of the intermediates, reduce time to market, and hence the overall cost of the end drug. Typically, pharmaceutical companies will contract for a certain annual volume of one or more production steps for a particular drug based on their expectations for demand for the end-product. Therefore, custom synthesis manufacturers play a critical partnership role for their pharmaceutical customers.

The intermediates used to produce modern drugs can be characterized by where they lie in the multi-step manufacturing process. Basic commodity intermediates are used in the early steps of the manufacturing process. These intermediates tend to require simple chemistry, have a low unit cost and can be provided by a large number of custom synthesis manufacturers. Barriers to entry for this market segment are low, and competition is primarily based on price. As a result, an increasing proportion of commodity intermediates are manufactured by Asian companies, particularly in India and China, as these companies have a significant labor and overhead cost advantage over North American and European companies. The later stages of the drug manufacturing process involve greater complexity in the chemical reactions necessary to produce the intermediates and a higher level of customization. A much smaller number of custom synthesis manufacturers have the expertise and available production facilities to offer the requisite level of service and volume to the customers. The manufacturing process for advanced intermediates and active pharmaceutical ingredients used in pharmaceutical products approved by the FDA or other applicable foreign regulatory agencies are also subject to the FDA’s current Good Manufacturing Practice and similar requirements by foreign regulatory agencies. These requirements create additional barriers to entry. Unit prices and barriers to entry are, therefore, much higher in this segment of the market. Groupe Novasep is active in this segment of the market.

22

We have a strong research and development team, and six facilities operated by us have implemented standards intended to meet current Good Manufacturing Practice requirements. Five have been inspected by the FDA and found to be in compliance with current Good Manufacturing Practice requirements. We have also developed strong customer relationships based on our research and development, rapid response to customers, consistent product quality and reliability of supply. Custom synthesis manufacturers tend to have close relationships with their pharmaceutical customers because specific manufacturing and related confidentiality requirements, which are common in the pharmaceutical industry, make substitution by alternative products and suppliers difficult. Some of our products are thus supplied to customers on a long-term basis or are produced for patented drugs whose patent expiration is not due for several years and where we act as a key supplier of intermediates. Leveraging our strong technological capabilities and customer relationships, we are currently developing a broad and diversified project pipeline across a number of customers, including advanced intermediates for potential new drugs. We are also focused on continued technological innovation. For example, we are currently introducing or using cutting edge technologies such as diborane chemistry at Dynamit Nobel Special Chemistry, MCC facilities at Finorga and TMC at Rohner.

Currently, Europe has the highest commercial significance for our Groupe Novasep segment. However, we believe growth opportunities exist in North America, particularly the United States. Though half of the production capacity for custom synthesis is installed in Europe, the majority of demand originates in North America. We intend to leverage our existing client base in the United States and significant supply relationship with one leading U.S. pharmaceutical company to further penetrate the North American market.

Principal Business Lines

Novasep Synthesis consists of the following four business lines:

Dynamit Nobel Special Chemistry, or DNSC. DNSC is a global market leader in hazardous chemistry, focusing on key technologies such as azide, carbon disulfide and diborane chemistries. The majority of compounds manufactured by DNSC is produced for pharmaceutical companies, with the remainder for agrochemicals and other industrial applications. DNSC offers a unique portfolio of core technologies based on hazardous starting materials, including explosive compounds, shock and friction sensitive compounds, highly inflammable gases and liquids, as well as toxic materials. DNSC’s strength is in azide chemistry, which is used to synthesize intermediates of final molecules that have anti-inflammatory, anti-bacterial and blood pressure reducing characteristics. Azide chemistry requires extremely high safety standards, state-of-the art purpose built infrastructure and trained employees. Few companies in Europe and the United States have the capabilities and permits to handle azide chemistry. Hazardous chemistry frequently offers a short and efficient synthetic route for the manufacturing of active pharmaceutical ingredients and advanced intermediates. Pharmaceutical companies are usually neither equipped nor licensed to handle hazardous chemistry in-house. DNSC benefits from its know-how, safety standards, permits and its reputation as a reliable supplier to the pharmaceutical industry.

Finorga. Finorga specializes in custom manufacturing of new chemical compounds and active pharmaceutical ingredients, involving complex and sophisticated chemical reactions used in multi-step synthesis. Finorga’s products are primarily aimed at the pharmaceutical industry, but also include selective fine chemicals for fast growing electronic industry applications, such as liquid crystals. Finorga offers a broad service platform, including quality control, regulatory support, research and development, process transfer, pilot and large-scale production. Finorga is contributing to the production of one of the top ten drugs worldwide.

Finorga differentiates itself from its competitors through its focus on sophisticated “chiral synthesis” technologies, which includes asymmetric synthesis and continuous chromatography. Chiral pharmaceutical compounds typically have two chiral forms, each of which can have different potency and side effects on a patient. Pharmaceutical companies are increasingly focused on isolating and producing the more effective chiral form of the compound, or the “enantiomerically pure” drug. We believe approximately 75% of drugs in the current industry pipeline fall into this category. However, the process of isolating the required chiral form during drug manufacturing requires highly complex chemistry and in the separation and purification of the enantiomers. Finorga is one of only a few companies worldwide to offer VARICOL® chiral separation, which is a highly effective and cost efficient way to separate and purify enantiomers. Finorga’s technologies also include TMC, which includes asymmetric hydrogenation and metal catalyzed C-C coupling. TMC refers to a technology platform that enables a highly selective and efficient transformation of specific functional groups of very complex molecules. Asymmetric hydrogenation is a technology that enables a synthesis of molecules with a high degree of purity cost-effectively. Metal catalyzed C-C coupling is a technology that helps build important core structures.

Rohner. Rohner produces chemicals on a custom synthesis and toll manufacturing basis. Rohner manufactures advanced intermediates and active pharmaceutical ingredients (“API’s”) for the pharmaceutical industry. As previously announced, the board of directors approved the Company’s plan to substantially downsize our manufacturing operations at the Rohner facility located in Pratteln, Switzerland and we have accordingly recorded impairment charges of $44.7 million in 2005 (See Note 17, “Impairment Charges,” for further detail). Rohner AG was sold in March 2006.

23

Seripharm. Seripharm is a former subsidiary of Aventis specializing in the production of high-potent (especially cytotoxic) active pharmaceutical ingredients. Seripharm also develops new high potent active pharmaceutical ingredients for pharmaceutical companies using our purification technologies.

Novasep Process

Novasep Process specializes in the development and optimization of purification processes as well as the design, installation, and on-site qualification of these customized purification systems in the pharmaceutical and bio-chemical industries. Novasep Process offers a broad range of proprietary technologies for industrial purification including preparative chromatography, large-scale chromatography, continuous chromatography processes (VARICOL®), ion exchange, crystallization and membranes. Novasep Process employs its full portfolio of purification technologies to address customers growing demand for customized purification solutions throughout their new product development process.

Principal Business Lines

Novasep Process consists of the following business lines:

Novasep. Novasep offers innovative solutions to pharmaceutical companies to assist them with the purification of molecules. Novasep’s core technologies are large-scale preparative high-pressure chromatography (batch or continuous) and crystallization. Novasep also assists pharmaceutical companies in developing second generation processes able to produce existing active pharmaceutical ingredients under better technical and economic conditions and in designing, installing and qualifying tailor made purification systems.

Applexion and Orelis. Applexion and Orelis offer separation solutions to purify molecules from natural biological sources. The key technologies include low-pressure chromatography (normally in continuous mode), ion-exchange, continuous crystallization and membranes (organic or mineral). Key markets addressed by these divisions are the sugar and sweetener industries and the production of bulk enzymes and antibiotics.

Competition

Competition in the market in which our Groupe Novasep segment competes is based on technological capabilities and know-how across a broad range of synthesis technologies, consistent product quality, reliability of supply and ability to meet customers’ production demands on a timely basis. Depending on the relevant technology, the main competitors are: Aerojet Fine Chemicals, Avecia Limited, Degussa, DSM N.V., Isochem, Lanxess, Lonza Group Ltd., Omnichem, Orgamol S.A. and PPG Sipsy.

Competition in our separation technologies is based on technological capabilities, consistent product quality, reliability of supply and ability to meet customers’ production demands on a timely basis. Some competitors include Bayer Technology Services, GE Healthcare and Millipore Corporation.

Customers

Groupe Novasep has a concentrated customer base. In this segment, our customers include some of the largest and most successful pharmaceutical companies, including Altana Pharma AG, Bristol-Myers Squibb Company, Novartis Pharma AG and Pfizer.

Raw Materials

We purchase raw materials and chemical intermediates from a large number of third parties. We have a broad raw material base, with the cost of no single raw material representing more than 2% of our cost of products sold in 2005. Raw materials constituted approximately 49% of our 2005 cost of products sold. The table below lists the ten most significant raw materials in 2005 and the principal products for which the materials were used.

24

Titanium-bearing slag, our largest raw material (in terms of dollars), is the most important raw material used in the production of specialty grade titanium dioxide in our Titanium Dioxide business line of our Titanium Dioxide Pigments segment. We purchase Titanium-bearing slag primarily from two suppliers under long-term contracts with fixed terms, one of which expires at the end of 2006.

As a result of the conversion from CCA to ACQ, in 2005 our principal raw materials for our Timber Treatment Chemical business in our Performance Additives segment has shifted from chromic acid to quaternary amines, solvents and copper. In our Timber Treatment Chemical business, we predominately source quaternary amines under a contract that expires in late 2008, with automatic annual renewals subject to termination by either party. We source solvents (monoethanolamine) used in our Timber Treatment Chemical business from two suppliers under contracts that expire in December 2006 (subject to automatic annual renewals except where terminated by either party) and December 2008. Prices under our solvent and quaternary amine contracts are tied to the ethylene price index and the natural gas index. We source copper, which is a commodity, from several sources. Prices for our copper purchases are tied to market conditions.

Historically, we have received iron oxide, from multiple sources and have not experienced any significant supply shortages. Iron oxide is primarily sourced from our plants in the United States, Italy and China, as well as from third parties in India and China.

PVC resin is a commodity product and its pricing is directly related to the price of ethylene and chlorine, as well as PVC industry operating rates and energy prices.

In our Clay-based Additives business line of our Performance Additives segment, quaternary amine is sourced under a long-term contract, which expires in late 2008 and is subject to quarterly adjustment for the price of tallow, the base component of quaternary amine.

In our Specialty Compounds segment, we use AOM to promote fire retardancy in certain wire and cable products. AOM is supplied under a contract with a fixed price that expires in December  2007. Some of the plasticizers we use in our Specialty Compounds segment are generic and considered a commodity product, while others are specific and considered a specialty product. Our supply contracts for plasticizers do not specify a fixed price, and most of them contain market price and discount adjustments.

Lithium brine is a primary raw material source for all lithium chemicals and is found in only a small number of locations, including most significantly for us, the Atacama Desert in Chile. We have a long-term contract with the Chilean government to mine lithium brine in the Atacama Desert in Chile, which we believe provides a secure long-term access to lithium. We experienced severe weather in early 2006 at our lithium ponds in Chile. As a result, we may experience shortages in lithium as a raw material.

Major requirements for our key raw materials and energy are typically satisfied pursuant to contractual agreements and medium- or long-term relationships with suppliers. We are not generally dependent on any one supplier for a major part of our raw materials requirements, but certain important raw materials are obtained from a few major suppliers. In general, where we have limited sources of raw materials, we have developed contingency plans to minimize the effect of any interruption or reduction in supply, such as sourcing from different facilities and multiple suppliers and utilizing alternative formulations.

Temporary shortages of raw materials may occasionally occur and cause temporary price increases. In recent years, these shortages have not resulted in unavailability of raw materials. However, the continuing availability and price of raw materials are affected by unscheduled plant interruptions occurring during periods of high demand, domestic and world market and political conditions, as well as the direct or indirect effect of governmental regulations. During periods of high demand, our raw materials are subject to significant price fluctuations, and, in the past, such fluctuations have had an adverse impact on the results of operations of our business. The impact of any future raw material shortages on our business as a whole or in specific geographic regions cannot be accurately predicted.

25

Intellectual Property

Our business is dependent to a large extent on our intellectual property rights, including patents and other intellectual property, trademarks and trade secrets. We believe that our intellectual property rights play an important role in maintaining our competitive position in a number of the markets we serve. We rely on technological know-how and formulation and application expertise in many of our manufacturing processes in order to develop and maintain our market positions. Where appropriate, we protect our new technology, applications and manufacturing processes by seeking patent protection. We have more than 2,000 patents and patent applications in key strategic markets worldwide, reflecting our commitment to invest in technology and covering many aspects of our products and processes for making those products. We also own and register in multiple jurisdictions numerous trade names and marks applicable to our business and products, which we believe are important to our business. In addition, we have entered into agreements, pursuant to which we license intellectual property from third parties for use in our business and we license certain intellectual property to third parties. For example, we developed the technology to produce ACQ pursuant to an exclusive license agreement with the right to sublicense from Domtar Inc. Under the term of the license, our Timber Treatment chemicals business of our Performance Additives segment pays a royalty to Domtar based upon the percent of net sales less certain costs. The license agreement expires in May 2007 in connection with the expiration of the patent and may be terminated by either party upon a material breach of the other party and the failure to cure. We also develop intellectual property with third parties as discussed below in “Research and Development.”

Research and Development

We are committed to further investing in our asset base and research effort. Our research and development costs were approximately 2% of our net sales in 2005. We incur certain expenses related to modifications and improvements in current products. In addition, we believe we allocate our research and development resources selectively based on the need and requirements for each business line to develop innovative products. Research and development costs are charged to expense, as incurred. Such costs were $60.8 million for the year ended December 31, 2005. For historic Rockwood businesses, such costs were $10.1 million and $8.7 million for the years ended December 31, 2004 and 2003, respectively, and such costs for the Dynamit Nobel businesses were $35.6 million and $32.4 million for the years ended December 31, 2004 and 2003, respectively.

The objective of our research and development effort is to develop innovative chemistries and technologies with applications relevant within targeted key markets. Research and development efforts are generally focused on both process development, which is the stage at which products move from development to manufacturing, and new product development. Each business line, however, also has selected long-term strategic projects with the aim to develop new competencies and technologies.

Each of our business lines manages its own research and development effort and has separate research and development facilities dedicated to its specific area. However, where technologically applicable, advances and findings are shared between business lines to foster greater cross-fertilization of ideas and applications.

In certain cases, we conduct research and development efforts with third parties, including universities, customers and other entities. We endeavor to obtain ownership of or license on terms favorable to us the intellectual property developed with a third party.

Seasonality

There is a seasonal effect on a portion of our sales due to the end-use of some of our products. In our pool and spa chemicals operations in our Water Treatment Chemicals business line of our Performance Additives segment, it is industry standard practice to offer significantly extended payment terms to customers prepared to purchase their spring and early summer requirements in the fourth quarter of the previous year. Following this pattern, the fourth quarter customarily includes large sales and shipments although the associated cash payments are not received until the second quarter of the following year. In addition, our Color Pigments and Services and Timber Treatment Chemicals business lines of our Performance Additives segment show some seasonality related to the outdoor construction market. As such, the first quarter has historically been the quarter where we experience the lowest sales. Also, along with the accounts receivable build in the first quarter discussed above, during this quarter we typically build inventory for the pool and spa business, as well as our construction related businesses, in anticipation of increased sales during the spring and summer months. Thus, the first quarter is usually the quarter with the highest working capital requirements for us. Other than these seasonal trends in certain end-use markets, our overall results of operations tend to show few seasonal effects.

International Operations

The following table presents net sales based on geographic area (attributed based on seller’s location):

The increase in net sales in 2005 and 2004 is primarily due to the acquisitions made in 2004 (see Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” for further detail).

The following table presents our long-lived assets located in the regions indicated:

Sales and Marketing

We sell our products and services globally. We generally sell our products and services primarily by using our direct sales forces, although we also sell through distributors in certain of our business lines, such as Color Pigments and Services, Clay-based Additives and Water Treatment Chemicals of our Performance Additives segment and Electronic Chemicals business line of our Electronics segment or by using third party sales representatives. Each of our direct sales forces is responsible for marketing only one of our business lines, and is administered pursuant to policies established by the management of that business line. Within each business line, these direct sales forces are organized based on geographic regions, end-use applications or sub-business divisions within the business line. As of December 31, 2005, our in-house sales forces consisted of 1,556 personnel worldwide.

Our direct sales forces interact with our customers to provide both purchasing advice and technical assistance. In general, our sales forces arrange and coordinate contact between our customers and our research and development or technical personnel to provide quality control and new product solutions. In certain of our businesses, such as the Surface Treatment and Fine Chemicals business lines of our Specialty Chemicals segment, most sales managers have a chemical engineering background with advanced degrees and significant technical experience in applying our products, and they play a critical role in developing client relationships and acquiring new clients. Our close interaction with our customers and tailored solutions have allowed us to develop and maintain strong customer relationships as well as focus our sales efforts on those customers who we believe will provide us with higher profit margins in recognition of our superior products, service and technical support.

Sales in each of our business lines are generally made on a purchase order basis. However, longer-term arrangements have been established with certain key customers.

Our marketing strategy is generally aimed at working directly with customers to gauge the success of our products, evaluate the need for improvements in product and process technology, and identify opportunities to develop new product solutions for our customers and their end-use markets. We also use media activities and lectures and participate in tradeshows as part of our sales and marketing effort.

We are subject to extensive environmental, health and safety laws in the United States, the European Union and elsewhere at the international, national, state and local levels. Many of these laws impose requirements relating to clean-up of contamination, and impose liability in the event of damage to human beings, natural resources or property, and provide for substantial fines, injunctions and potential criminal sanctions for violations. Our products, including the raw materials we handle, are also subject to rigorous industrial hygiene regulations and investigation. The nature of our operations exposes us to risks of liability for breaches of these laws and regulations as a result of the production, storage, transportation and sale of materials that can cause contamination or personal injury when released into the environment. Environmental laws are subject to change and have tended to become stricter over time. Such changes in environmental laws, or the enactment of new environmental laws, could result in materially increased capital, operating and compliance costs.

Safety, Health and Environmental Systems

We are committed to achieving and maintaining compliance with all applicable safety, health and environmental (“SHE”) legal requirements, and our subsidiaries have developed policies and management systems that are intended to identify the SHE legal requirements applicable to our operations, enhance compliance with such requirements, ensure the safety of our employees, contractors, community neighbors and customers and minimize the production and emission of wastes and other pollutants. Although SHE legal requirements are constantly changing, these SHE management systems are designed to assist us in meeting our compliance goals and minimizing overall risk to us.

SHE Capital Expenditures

We may incur future costs for capital improvements and general compliance under SHE laws. For the year December 31, 2005, our capital expenditures for SHE matters totaled approximately $32.8 million, excluding costs to maintain and repair pollution control equipment. For 2006, we estimate capital expenditures for compliance with SHE laws to be at similar levels; however, because capital expenditures for these matters are subject to changes in existing and new SHE laws, we cannot provide assurance that our recent expenditures will be indicative of future amounts required to comply with these laws.

Regulatory Developments

In October 2003, the European Commission adopted a proposal for a new European Union (“EU”) framework for chemicals known as the Registration, Evaluation and Authorization of Chemicals, or REACH which will significantly expand the European Union’s regulation of chemicals. As currently proposed, REACH would include requirements that certain manufacturers and importers of chemicals register those chemicals, perform health and environmental risk analyses of those chemicals, and in certain instances, obtain authorizations for the use of the chemicals. As a specialty chemicals company, it is possible that we are the only manufacturer of one or more substances to be regulated under REACH and thus could potentially bear the full cost of compliance with REACH for some or all of our products. We estimate we have over 400 products that might be subject to REACH, which is scheduled to become an EU directive in early 2007; compliance with REACH will be required starting in 2008.

Under the European Union Integrated Pollution Prevention and Control Directive (“IPPC”), European Union member governments are to adopt rules and implement a cross-media (air, water and waste) environmental permitting program for individual facilities. IPPC requires a consistent application of Best Available Techniques, or BAT, throughout the European Union. Generally, by 2007, facilities located within the European Union must be operating consistent with BAT. While the EU countries are at varying stages in their respective implementation of the IPPC permit program, we have submitted all necessary IPPC permit applications required to date, and in some cases received completed permits from the applicable government agency. We expect to submit all other IPPC applications and related documents on a timely basis as the various countries implement the IPPC permit program. Although we do not know with certainty what each IPPC permit will require, we believe, based upon our experience with the permits received to date, that the costs of compliance with the IPPC permit program will not be material to our results of operations, financial position or liquidity.

The Kyoto Protocol is an amendment to an international treaty on global warming. The Protocol establishes significant emission reduction targets for six gases considered to have global warming potential, referred to as greenhouse gases. The Protocol was adopted in 1997 and became effective in February 2005 in over 140 countries that have ratified it. The EU, including Germany and other countries where we have interests, ratified the Kyoto Protocol in 2002. By ratifying, the EU, and its member states’ agreed to enact regulation that reduces the emission of greenhouse gases or engage in a trading system covering carbon dioxide emissions by January 1, 2005. Such a system became effective at the start of 2005. The new regulation directly affects our power plants at the Duisburg and Langelsheim sites in Germany, as well as the power plant being operated by a third party on one of our sites. Rockwood and such third party may be required to purchase carbon dioxide credits, which could result in increased operating costs, or may be required to develop additional cost-effective methods to reduce carbon dioxide emissions, which could result in increased capital expenditures. The new regulation indirectly affects our other operations in the EU, which may experience higher energy costs from

28

third party providers. We continue to evaluate options in order to comply with the Protocol, however, we do not expect this to have a material impact on our cash flow or results of operations.

Remediation Liabilities

Environmental laws have a significant effect on the nature and scope of any clean-up of contamination at current and former operating facilities, the costs of transportation and storage of chemicals and finished products and the costs of the storage and disposal of wastes. In addition, “Superfund” statutes in the United States as well as statutes in other jurisdictions impose strict, joint and several liability for clean-up costs on the entities that generated waste and/or arranged for its disposal at contaminated third party sites, as well as the past and present owners and operators of contaminated sites. All responsible parties may be required to bear some or all clean-up costs regardless of fault, legality of the original disposal or ownership of the disposal site.

Environmental contamination is known to exist at certain of our present and former facilities, including our facilities located in Turin, Italy; St. Fromond, St. Cheron and Sens, France; Hainhaussen, Troisdorf, Schlebusch, Stadeln, Duisburg, Plochingen, Marktredwitz, Ronnenberg-Empelde and Langelsheim, Germany; Oss, The Netherlands; Kidsgrove, Sudbury and Barrow, U.K.; Boksburg East, South Africa; Pratteln, Switzerland and in the United States, in Valdosta, Georgia, Beltsville, Maryland, Harrisburg, North Carolina, Laurens, South Carolina, Silver Peak, Nevada and La Mirada, California. Soil contamination is also known to exist at our facilities at Freeport, Texas, Chasse-sur-Rhone, France, Sudbury, U.K. and Sumperk in Czech Republic; however, no further regulatory remedial actions are currently required for these facilities and any liabilities arising from such contamination is covered by indemnity obligations or the previous owners of these facilities with the exception of Freeport. We are currently operating groundwater remediation systems at its Hainhaussen, Pratteln, Valdosta, and Silver Peak facilities. We also operate ground water remediation systems at its Schlebusch, Plochingen, Marktredwitz, Stadeln, Troisdorf, and Laurens facilities, for which prior owners or insurers have assumed responsibility. We have recently completed a soil remediation project at the Company’s facility in St. Cheron and are currently awaiting regulatory approval. We also continue to monitor groundwater at the Beltsville facility, which was previously the subject of a soil removal action. Groundwater is also monitored at the St. Fromond and Barrow facilities due to prior spills and at the Harrisburg facility due to a landfill closure. We are also required to monitor groundwater quality at our facility at Mourenx, France. We believe that additional environmental studies, and possibly environmental remediations, will be required at the Pratteln and Harrisburg facilities. We are also in the process of determining appropriate remedial actions with the regulatory authorities at the following locations: Duisburg, Langelsheim, Troisdorf, Turin and La Mirada. Furthermore, as a result of facility closings, divestitures and offsite disposal activities such as a former disposal site in Laurel, Maryland, we are responsible for the following other matters: contamination beneath divested portions of the manufacturing facility in Troisdorf; contamination at a closed Specialty Chemicals facility in Houston, Texas, contamination at a former Specialty Chemicals facility in Sunbright, Virginia, contribution towards the clean-up of three industrial landfills in the Basel, Switzerland area, groundwater remediation at Stadeln and former sites operated by Dynamit Nobel’s previously divested explosives business. We are also a de minimis participant in several Superfund matters.

Although we cannot provide assurances in this regard, we do not believe that these issues will have a material adverse effect on its business or financial condition, but may have a material adverse effect on the results of operations or cash flows in any given quarterly or annual reporting period. Nonetheless, the discovery of contamination arising from present or historical industrial operations at some of our and our predecessor’s former and present properties and/or at sites the Company and its predecessor disposed wastes could expose us to cleanup obligations and other damages in the future.

Government Enforcement Proceedings and Civil Litigation

During the course of our business, we may receive notices of violation, enforcement and other complaints from regulatory agencies alleging non-compliance with applicable SHE law. Currently, we are party to a consent order with the Metropolitan Sewer District (“MSD”) in Saint Louis, Missouri to reduce ammonia concentrations in wastewater discharge to a city treatment plant. MSD’s new National Pollution Discharge Elimination System (“NPDES”) permit will require us to reduce the facility’s ammonia discharge by an average of 50% by December 31, 2008. We are evaluating various options to reduce the amount of ammonia discharged. Although we will be required to make capital expenditures in connection with this matter, we do not believe that this issue will have a material adverse effect on our business or financial condition.

Environmental Indemnities

Pursuant to the environmental deed entered into in connection with the KKR Acquisition, Degussa, as successor to Laporte, is required to indemnify us and our subsidiaries for certain environmental matters that relate to the business as conducted prior to the closing of the KKR Acquisition. The environmental deed provides that Degussa will indemnify us and our subsidiaries for claims for which notice is given within a period of two years for breaches of representations and warranties, which expired in 2002, and five years, which expired in September 2005, for claims related to the contamination of our properties or our subsidiaries’ properties (inclusive of contamination which leaks or escapes from our properties or our subsidiaries’ properties). These indemnity obligations are subject to a minimum per matter loss of $0.2 million and are further subject to a $5.0 million deductible for the indemnity to be available. In addition, the environmental deed provides that Degussa will indemnify us and our subsidiaries for claims relating to properties that were formerly owned, occupied or used as of November 20, 2000, as well as properties owned by third parties (inclusive of disposal of waste and certain other identified issues prior to November 20, 2000). The environmental deed provides that in this instance, Degussa will be responsible for reasonable costs and expenses incurred.

29

In addition, pursuant to the sale and purchase agreement entered into in connection with the Dynamit Nobel Acquisition, mg technologies ag (now known as GEA Group) and its subsidiary, MG North America Holdings Inc., are required to indemnify us and our subsidiaries for 50% of the excess amount of losses over the amount of the related reserves (in the case of known claims) and 50% of claims (in the case of unknown claims) related to the contamination of our or our subsidiaries’ properties, if notified within ten years. If mg technologies and MG North America Holdings’ responsibility for contamination matters cannot be proven, a sliding scale reduces the percentage further for each year during the five-year period from year six to ten. mg technologies and MG North America Holdings are also obligated to indemnify us for 85% of claims related to legacy site matters, such as environmental matters relating to properties or businesses owned or operated by Dynamit Nobel prior to, but not on, the closing of Dynamit Nobel Acquisition, if notified within ten years. In addition, mg technologies and MG North America Holdings are obligated to indemnify us for 50% of the excess amount of losses over the amount of the related reserves for operational compliance matters, if notified by December 31, 2006, and 50% of the excess amount of losses over the amount of the related reserves (in the case of known claims) and 50% of claims (in the case of unknown claims) related to certain environmental damage claims unknown at the time of the closing of the Dynamit Nobel Acquisition, if notified within ten years. All of these indemnity obligations are subject to different minimum per-claim thresholds depending on whether the matter was disclosed or not, and on the subject matter, ranging between €100,000 and €750,000 ($117,960 and $884,700 using the December 31, 2005 exchange rate of €1.00=$1.1796) depending on the type of claim. The indemnity obligations are further subject to certain deductibles, exclusions and limitations. Furthermore, mg technologies and MG North America Holdings are obligated to indemnify us for certain environmental risks arising from certain “shared site” structures for a duration of ten years. This indemnity obligation is not subject to the percentages, de minimis exclusions, deductibles and thresholds described above, and it is not subject to most of the general limitations.

In the event we seek indemnity under any of these agreements or through other means, there can be no assurance that mg technologies, MG North America Holdings, Degussa or any other party who may have obligations to indemnify us will adhere to their obligations and we may have to resort to legal action to enforce our rights under the indemnities. In addition, we may be required to make indemnity payments in connection with certain environmental matters. However, we do not believe that resolution of the known environmental matters subject to indemnification obligations owed to us will have a material adverse effect on our business or financial condition, but may have a material adverse effect on the results of operations or cash flow in any quarterly or annual reporting period.

Environmental Reserves

We have established financial reserves relating to anticipated environmental cleanup obligations, site reclamation and remediation and closure costs. Liabilities are recorded when potential liabilities are either known or believed to be probable and can be reasonably estimated. Our liability estimates are based upon available facts, existing technology, past experience and, in some instances where the remediation costs are being paid directly by our insurers, insurance recoveries, and are generated by several means, including state-mandated schedules, environmental consultants and internal experts, depending on the circumstances. On a consolidated basis, we have accrued approximately $44.8 million and $51.9 million for known environmental liabilities as of December 31, 2005 and 2004, respectively, all of which are classified as other non-current liabilities on our consolidated balance sheets for such periods. The decrease in 2005 is primarily attributable to the impact of foreign exchange rates. Included in the $44.8 million as of December 31, 2005 is €6.5 million ($7.6 million using the December 31, 2005 exchange rate of €1.00=$1.1796) that is discounted using a 5.0% discount rate (undiscounted amount equals $11.7 million), and €1.9 million ($2.2 million) that is discounted using a 5.5% discount rate (undiscounted amount equals $2.9 million). Included in the $51.9 million as of December 31, 2004 is €6.5 million ($8.8 million using the December 31, 2005 exchange rate of €1.00=$1.3593) that is discounted using a 5.0% discount rate (undiscounted amount equals $13.5 million), and €2.4 million ($3.3 million) that is discounted using a 5.5% discount rate (undiscounted amount equals $5.2 million). In certain cases, our remediation liabilities are payable over periods of up to 30 years. At December 31, 2005, the environmental reserve related to the Rohner facility within our Groupe Novasep segment was $10.5 million. As we announced, Rohner AG was sold in March 2006 (see Note 17, “Impairment Charges,” for further detail).

We believe these accruals are adequate based on currently available information. We may incur losses in excess of the amounts accrued, however, based on currently available information we do not believe the additional amount of potential losses would have a material effect on the Company’s results of operations, cash flows or financial condition, but may have a material effect on the results of operations or cash flow in any given quarterly or annual reporting period. We are unable to estimate the amount or range of any potential incremental charges should facts and circumstances change and may in the future revise our estimates based on new information becoming available.

We are obligated to undertake soil remediation at two of our facilities in Europe in the event manufacturing operations are discontinued there at some future date. In addition, in the event that manufacturing operations are discontinued at any of our other facilities with known contamination, regulatory authorities may impose more stringent requirements on us including soil remediation. We do not contemplate any such action occurring in the foreseeable future, as these facilities’ remaining lives are indefinite. Given the

30

indeterminate useful life of these facilities and the corresponding indeterminate settlement date of any soil remediation obligations we do not have sufficient information to estimate a range of potential settlement dates for the obligations. Consequently, we cannot employ a present value technique to estimate fair value and, accordingly, we have not accrued for any environmental related costs to remediate soil at these facilities.

We believe these environmental matters will not have a material adverse effect on our business or financial condition. However, these matters may have a material adverse effect on our results of operations or cash flows in any given quarterly or annual reporting period.

FDA Regulation

Our Groupe Novasep, Advanced Ceramics and to a lesser extent, our Specialty Chemicals segments are also subject to regulation by the FDA with respect to certain products we produce, including pharmaceutical intermediates, active pharmaceutical ingredients and ceramic-on-ceramic ball head and liner components used in hip joint prostheses systems. Foreign, state, local and other authorities also may regulate us and our products. Regulatory agencies have established requirements that apply to the design, manufacture and marketing of pharmaceutical and medical device products. We sell our pharmaceutical intermediates, active pharmaceutical ingredients and ceramic-on-ceramic components to other companies that also may be regulated by such authorities.

Premarket Approval. While we are not required to seek FDA approvals for our pharmaceutical intermediates and active pharmaceutical ingredients, the customers to whom we supply such products may be subject to FDA approval requirements prior to testing a new drug on humans as well as marketing a new drug for commercial use in the United States. Our customers with FDA approval for the finished drug may also be required to obtain FDA approval of design, manufacturing or labeling changes to the pharmaceutical intermediates and active pharmaceutical ingredients used in their finished products.

Medical devices also are subject to extensive regulation by the FDA prior to commercial distribution in the United States, including premarket approval, or PMA, which is required for devices deemed to pose the greatest risk and certain other devices. Our Advanced Ceramics segment currently supplies ceramic-on-ceramic ball head and liner components to manufacturers for incorporation into their total hip prostheses systems, which are subject to the FDA’s PMA requirements. In addition, our Advanced Ceramics business or our customers who have obtained PMA approval may be required to obtain FDA approval for changes to the design, manufacturing or labeling of our ceramic-on-ceramic ball head and liner components. Also, other medical devices, which our Advanced Ceramics segment seeks to produce in the future, such as knee replacement products, would likely require FDA approval.

Compliance Requirements. Once on the market, drug manufacturers, the suppliers of drug intermediates, and medical device manufacturers are subject to numerous post-market regulations. For our pharmaceutical intermediates business within our Groupe Novasep segment, we are required to comply with the FDA’s current Good Manufacturing Practices, which cover all facets of drug manufacturing and distribution including: organization and personnel; buildings and facilities; equipment; control of components and drug product containers and closures; production and process controls; packaging and labeling control; holding and distribution; laboratory controls; recordkeeping and reporting; and returned and salvaged drug products.

Finished device manufacturers such as our customers who manufacture hip prostheses systems are subject to the FDA’s Quality System Regulation, or QSR, which requires quality assurance practices and procedures that address, among other things: management responsibility, audits and training; design controls; purchasing controls; identification and traceability of components; production and process controls; acceptance activities; handling of nonconforming product; the initiation of corrective and preventive actions; labeling and packaging controls; handling, storage and distribution of products; and complaint handling and record keeping. The FDA does not directly require component suppliers of finished medical devices to comply with the QSR. However, because our ceramic-on-ceramic ball head and liner components are critical elements of hip joint prostheses systems, our customers may require us to comply with some or all of the QSR. Moreover, the FDA may in the future take the position that the types of components that we supply meet the definition of a finished device and are thus subject to the QSR. Our current contracts with our customers of ceramic-on-ceramic ball head and liner components require us to comply or assist our customers in complying with various FDA regulatory requirements.

The FDA’s inspectional authority extends to both component suppliers and pharmaceutical intermediates manufacturers. Pursuant to this authority, the FDA has the ability to conduct inspections at our facilities at which we manufacture our pharmaceutical intermediates or ceramic-on-ceramic ball head and liner components.

If we or our customers violate FDA or other governmental regulatory requirements during either the pre- or post-marketing stages, there may be various adverse consequences. For example, in the United States, the FDA has the authority to impose: fines, injunctions, and civil penalties; recall or seizure of products; operating or import restrictions, partial suspension or total shutdown of production; the FDA’s delay in granting approval or refusal to grant approval of new products; or withdrawal of the submission or the approved product from the market.

Employees

As of December 31, 2005, we had 10,774 employees, with 72% located in Europe, 19% in the United States and the remaining 9% located in the rest of the world. Of our employees, approximately 3,109, or 29%, are subject to either collective bargaining agreements or other similar arrangements.

We observe local customs, legislation and practice in labor relations and, where applicable, in negotiating collective bargaining agreements. Management believes that its relations with employees and their representatives are good. We have not suffered any material work stoppages or strikes in our worldwide operations in the last five years.

Item 1A. Risk Factors.

You should carefully consider these risk factors in evaluating our business. In addition to the following risks, there may also be risks that we do not yet know of or that we currently think are immaterial that may also affect our business. If any of the following risks occur, our business, results of operations, cash flows or financial condition could be adversely affected.

Substantial Leverage—Our available cash and access to additional capital may be limited by our substantial leverage.

We are highly leveraged and have significant debt service obligations. As of December 31, 2005, we had $2,843.8 million of indebtedness outstanding and total stockholders’ equity of $834.7 million. This high level of indebtedness could have important negative consequences to us and you, including:

•                  we may have difficulty obtaining financing in the future for working capital, capital expenditures, acquisitions or other purposes;

•                  we will need to use a substantial portion of our available cash flow to pay interest and principal on our debt, which will reduce the amount of money available to finance our operations and other business activities;

•                  some of our debt, including borrowings under the senior secured credit facilities, will have variable rates of interest, which will expose us to the risk of increased interest rates;

•                  our debt level increases our vulnerability to general economic downturns and adverse industry conditions;

•                  our debt level could limit our flexibility in planning for, or reacting to, changes in our business and in our industry in general;

•                  our substantial amount of debt and the amount we need to pay to service our debt obligations could place us at a competitive disadvantage compared to our competitors that have less debt; and

•                  our failure to comply with the financial and other restrictive covenants in our debt instruments which, among other things, require us to maintain specified financial ratios and limit our ability to incur debt and sell assets, could result in an event of default that, if not cured or waived, could cause our lenders to terminate commitments under our debt agreements, declare all amounts, including accrued interest, due and payable, and enforce their rights in respect of collateral.

Our cash interest expense for the year ended December 31, 2005 was $203.2 million. At December 31, 2005, we had $1,754.8 million of variable rate debt. After including the notional amounts of variable to fixed interest rate swaps, the variable amount was $471.4 million. A 1% increase in the average interest rate would increase future interest expense by approximately $4.7 million per year. Our debt service for 2006 is expected to be $297.0 million. See Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Liquidity and Capital Resources,” “Liquidity,” “Contractual Obligations” for years beyond 2006.

32

Additional Borrowings Available—Despite our substantial leverage, we and our subsidiaries will be able to incur more indebtedness. This could further exacerbate the risks described above, including our ability to service our indebtedness.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. Although our indirect, wholly-owned subsidiary, Rockwood Specialties Group, Inc.’s (“Group” or “Group’s”) senior secured credit facilities and the indentures governing the 2011 Notes and the 2014 Notes contain restrictions on the incurrence of additional indebtedness, such restrictions are subject to a number of qualifications and exceptions, and under certain circumstances indebtedness incurred in compliance with such restrictions could be substantial. As of December 31, 2005, the revolving credit facility under the senior secured credit facilities provided for additional borrowings of up to $196.0 million, after giving effect to $24.0 million of letters of credit issued on our behalf and outstanding borrowings of $30.0 million under the revolving credit facility. In addition, the term loans and the availability under the revolving credit facility under the senior secured credit facilities may be increased by up to $250.0 million in aggregate, subject to certain exemptions and provided that Group procures lender commitments for such increase. To the extent new debt is added to our debt levels, the substantial leverage risks described above would increase.

Restrictive Covenants in Our Debt Instruments—Our debt instruments contain a number of restrictive covenants which may limit our ability to finance future operations or capital needs or engage in other business activities that may be in our interest.

Group’s senior secured credit agreement and indentures governing the 2011 Notes and 2014 Notes impose, and the terms of any future indebtedness may impose, operating and other restrictions on us. Such restrictions will affect, and in many respects limit or prohibit, among other things, our ability to take certain actions. In addition, Group’s senior secured credit facilities also require us to achieve certain financial and operating results and maintain compliance with specified financial ratios. Our ability to comply with these ratios may be affected by events beyond our control. The restrictions and financial covenants contained in Group’s senior secured credit agreement and indentures governing the 2011 Notes and 2014 Notes could adversely affect our ability to finance our operations, acquisitions, investments or strategic plans or other capital needs or to engage in other business activities that would be in our interest.

A breach of any of these covenants or our inability to comply with the required financial ratios could result in a default under the senior secured credit facilities and/or the indentures. If an event of default occurs under the senior secured credit facilities, which includes an event of default under the indentures governing the 2011 Notes and 2014 Notes, the lenders could elect to:

•                  declare all borrowings outstanding, together with accrued and unpaid interest, to be immediately due and payable;

•                  require us to apply all of our available cash to repay the borrowings; or

•                  prevent us from making debt service payments on the 2011 Notes and 2014 Notes;

any of which would result in an event of default under the 2011 Notes and 2014 Notes. The lenders will also have the right in these circumstances to terminate any commitments they have to provide further financing. If we were unable to repay or otherwise refinance these borrowings when due, our lenders could sell the collateral securing the senior secured credit facilities, which constitutes substantially all of our and our subsidiaries’ assets.

Risks Associated with Acquisitions—We may not be able to successfully integrate acquisitions we may make in the future.

The process of combining acquisitions or combinations with Rockwood involves risks. We may face difficulty completing the integration of the new operations, technologies, products and services of acquisitions or combinations, and may incur unanticipated expenses related to those integrations. The difficulties of combining operations may be magnified by integrating personnel with differing business backgrounds and corporate cultures. Failure to successfully manage and integrate acquisitions with our existing operations could lead to the potential loss of customers of the acquired business, the potential loss of employees who may be vital to the new operations, the potential loss of business opportunities or other adverse consequences that could affect our financial condition and results of operations. Even if integration occurs successfully, failure of any future acquisition to achieve levels of anticipated sales growth, profitability or productivity comparable with those achieved by our existing operations, or otherwise not perform as expected, may adversely impact our financial condition and results of operations.

Limited Relevance of Financial Information—Our historical and pro forma financial information may not be representative of our results as a combined company.

The pro forma financial information presented in 2004 is based on certain assumptions regarding the integration of Dynamit Nobel that we believe are reasonable. Our assumptions may prove to be inaccurate over time. Accordingly, the historical and pro forma financial information included herein may not reflect what our results of operations and financial condition would have been had we been a combined entity during the periods presented, or what our results of operations and financial condition will be in the future.

33

Net Loss—We have a history of losses and may experience losses in the future and we cannot be certain that our net operating loss carryforwards will continue to be available to offset our tax liability.

We have incurred net losses in the past and we may incur net losses in the future. We incurred net losses of $216.1 million and $91.7 million in 2004 and 2003, respectively.

We may not achieve profitability in the future and we may not generate cash flow sufficient to meet debt service obligations and other capital requirements, such as working capital and maintenance capital expenditures.

As of December 31, 2005, we had deferred tax assets of $166.2 million related to worldwide net operating loss carryforwards for which we had valuation allowances of $58.4 million and an additional valuation allowance of $18.7 million for deferred tax assets. If our operating performance deteriorates in the future in certain tax jurisdictions, we may be unable to realize these net operating loss carryforwards and we may be required to record an additional valuation allowance.

Currency Fluctuations—Because a significant portion of our operations is conducted in foreign currencies, fluctuations in currency exchange rates may adversely impact our financial condition and results of operations and may affect the comparability of our results between financial periods.

Our operations are conducted by subsidiaries in many countries. The results of their operations and financial condition are reported in the local currency and then translated into U.S. dollars at the applicable exchange rates for inclusion in our consolidated financial statements. The exchange rates between some of these currencies and the dollar in recent years have fluctuated significantly and may continue to do so in the future. As a result of the Dynamit Nobel Acquisition, a significantly larger portion of our net sales and cost of products sold is now denominated in euros. Approximately 53% of our 2005 net sales were derived from subsidiaries whose local currency is the euro. This increases the impact of the fluctuation of the euro against the U.S. dollar.

Furthermore, because a portion of our debt is denominated in euros, which as of December 31, 2005 equaled an aggregate of €962.4 million ($1,135.2 million based on the December 31, 2005 exchange rate of €1.00 = $1.1796), we are subject to fluctuation in the exchange rate between the U.S. dollar and the euro. For example, the dollar-euro noon buying rate announced by the Federal Reserve Bank of New York increased from $1.00 = €1.065 on December 31, 2000 to $1.00 = €0.8477 on December 31, 2005. Being subject to this currency fluctuation may have an adverse effect on the carrying value of our debt and may also affect the comparability of our results of operations between financial periods. As of December 31, 2005, a weakening or strengthening of the euro against the U.S. dollar by $0.01 would decrease or increase, respectively, by $9.6 million the U.S. dollar equivalent of our total euro-denominated debt of €962.4 million. In addition, because our financial statements are reported in U.S. dollars, the translation effect of such fluctuations has in the past significantly impacted, and may in the future, significantly impact the carrying value of our debt and results of operations and may affect the comparability of our results between financial periods. We also incur currency transaction risk whenever we enter into either a purchase or sale transaction using a currency other than the local currency of the transacting entity.

We may not be able to effectively manage our currency translation and/or transaction risks and volatility in currency exchange rates may have a material adverse effect on the carrying value of our debt and results of operations.

Regulation of Our Raw Materials, Products and Facilities—Our business could be adversely affected by regulation to which our raw materials, products and facilities are subject.

Some of the raw materials we handle, and our products and facilities, are subject to government regulation. These regulations affect the manufacturing processes, uses and applications of our products.

In addition, some of our subsidiaries’ products contain raw materials, such as arsenic pentoxide, carbon disulfide, lithium carbonate, tetrahydrofuran, copper, chromic acid, silica, zinc chromate and lead, that are deemed hazardous materials in certain situations. The use of these materials is regulated and some of these regulations require product registrations, which also are subject to renewal and potential revocation. These regulations may affect our ability to market certain chemicals we produce.

There is also a risk that other key raw materials or one or more of our products may be found to have, or be recharacterized as having, a toxicological or health-related impact on the environment or on our customers or employees. If such a discovery or recharacterization occurs, the relevant materials, chemicals or products, including products of our customers incorporating our materials or chemicals, may be recalled or banned or we may incur increased costs in order to comply with new regulatory requirements. Change in regulations, or their interpretation, may also affect the marketability of certain of our products.

Manufacturing Hazards—Hazards associated with chemical manufacturing could adversely affect our results of operations.

Due to the nature of our business, we are exposed to the hazards associated with chemical manufacturing and the related storage and transportation of raw materials, products and wastes in our manufacturing facilities or our distribution centers, such as fires, explosions and accidents. These hazards could lead to an interruption or suspension of operations and have an adverse effect on the productivity and profitability of a particular manufacturing facility or on our company as a whole. Other hazards include:

34

•                  piping and storage tank leaks and ruptures;

•                  mechanical failure;

•                  employee exposure to hazardous substances;

•                  chemical spills and other discharges or releases of toxic or hazardous substances or gases; and

•                  inclement weather and natural disasters.

These hazards may cause personal injury and loss of life, damage to property and contamination of the environment, which could lead to government fines or work stoppage injunctions and lawsuits by injured persons. For example, our subsidiaries had been named as defendants in a wrongful death suit filed by the family of an employee who was fatally injured in an accident in our Clay-based Additives facility in Gonzales, Texas. While we are unable to predict the outcome of this case and other such cases, if determined adversely to us, we may not have adequate insurance to cover such claims and, if not, we may not have sufficient cash flow to pay for such claims. Such outcomes could adversely affect our customer goodwill, cash flow and results of operations.

Raw Materials—Fluctuations in costs of our raw materials or, our access to supplies of our raw materials could adversely affect our results of operations.

Although no single raw material represented more than 2% of our cost of products sold in 2005, raw material costs generally account for a high percentage of our total costs of products sold. In 2005, raw materials constituted approximately 49% of our cost of products sold. We generally purchase raw materials based on supply agreements linked to market prices and therefore our results of operations are subject to short-term fluctuations in raw materials prices. These fluctuations limit our ability to accurately forecast future raw material costs and hence our profitability.

Many of the raw materials we use are commodities, and the price of each can fluctuate widely for a variety of reasons, including changes in availability, major capacity additions or reductions or significant facility operating problems. Historically, there have been some price increases we have not been able to pass through to our customers. This trend may continue in the future.

In addition, titanium-bearing slag used in our Titanium Dioxide Pigments segment is our largest raw material (in terms of dollars) and is sourced primarily from one supplier in Canada. If our supplier is unable to meet its obligations under our present supply agreement or we are unable to enter into new supply arrangements on competitive terms when our existing short-term supply arrangements expire, we may be forced to pay higher prices to obtain these necessary raw materials. Furthermore, certain of our raw materials, such as cesium and lithium salts, are sourced from countries where political, economic and social conditions may be subject to instability. In addition, one of our raw materials, lithium brine, requires a period of gestation before it can be used to produce lithium compounds. We experienced severe weather in early 2006 at our lithium ponds in Chile. As a result, we may experience shortages in lithium as a raw material. In the event there is an increase in market demand for lithium products, we may not be able to respond to such market demand on a timely basis. Any interruption of supply or any price increase of raw materials could result in our inability to meet demand for our products, loss of customer goodwill and higher costs of producing our products.

Energy Costs—Fluctuations in energy costs could have an adverse effect on our results of operations.

Energy purchases in 2005 constituted approximately 5% of Rockwood’s cost of products sold. Although energy costs increased in 2005, there was not a material change from the prior year in the percentage of our energy purchases to cost of products sold. Fluctuations in the price of energy limit our ability to accurately forecast future energy costs and consequently our profitability. For example, in 2004, natural gas prices were volatile in North America and continued to increase in 2005, due in part to global political conditions and extreme weather conditions, including Hurricanes Katrina and Rita. In contrast, natural gas prices in Europe, where our Titanium Dioxide Pigments segment is located, have historically been relatively stable. Rising energy costs may also increase our raw material costs. If energy prices fluctuate significantly, our business, in particular, our Titanium Dioxide segment, or results of operations may be adversely affected. In addition, rising energy costs also negatively impact our customers and the demand for our products. These risks will be heightened if our customers or production facilities are in locations experiencing severe energy shortages.

Environmental, Health and Safety Regulation—Compliance with extensive environmental, health and safety laws could require material expenditures or changes in our operations.

Our operations are subject to extensive environmental, health and safety laws and regulations at national, international and local levels in numerous jurisdictions. In addition, our production facilities and a number of our distribution centers require operating permits that are subject to renewal and, in some circumstances, revocation. The nature of the chemicals industry exposes us to risks of liability under these laws and regulations due to the production, storage, transportation, disposal and sale of chemicals and materials that can cause contamination or personal injury if released into the environment. In 2005, our capital expenditures for safety, health and environmental matters were approximately $32.8 million. For 2006, we estimate capital expenditures for compliance with SHE laws to be at similar levels; however, because capital expenditures for these matters are subject to changes in and new SHE laws, we cannot provide assurance that our recent expenditures will be indicative of future amounts to comply with these laws. We may be materially impacted in the future by the Registration, Evaluation and Authorization of Chemicals, or REACH, program proposed by the European Union, which is scheduled to require compliance beginning in 2008.

35

Compliance with environmental laws generally increases the costs of registration/approval requirements, the costs of transportation and storage of raw materials and finished products, as well as the costs of the storage and disposal of wastes, and could have a material adverse effect on our results of operations. We may incur substantial costs, including fines, damages, criminal or civil sanctions and remediation costs, or experience interruptions in our operations, for violations arising under these laws or permit requirements. Furthermore, environmental laws are subject to change and have tended to become stricter over time. Such changes in environmental laws or their interpretation, or the enactment of new environmental laws, could result in materially increased capital expenditures and compliance costs.

In addition, the discovery of contamination arising from historical industrial operations at some of our former and present properties has exposed us, and in the future may continue to expose us, to cleanup obligations and other damages. For example, soil and groundwater contamination is known to exist at several of our facilities, including some that we acquired in the Dynamit Nobel Acquisition. At December 31, 2005, we had approximately $44.8 million in reserves for estimated environmental liabilities, of which approximately $38.7 million is for estimated liabilities related to environmental matters in connection with the Dynamit Nobel Acquisition.

Under the sale and purchase agreement, mg technologies ag is required to indemnify us for certain environmental matters, subject to certain limitations. However, mg technologies ag may not adhere to its indemnity obligations to us and the indemnity may not adequately cover any related environmental matters, and we may have to institute proceedings to pursue recovery for such matters. Such legal proceedings may be costly and may require a substantial amount of management attention. See Item 1, “Business,” “Safety, Health and Environmental Matters.”

Environmental Indemnities—We may be subject to environmental indemnity claims relating to properties we have divested.

The discovery of contamination arising from properties that we have divested may expose us to indemnity obligations under the sale agreements with the buyers of such properties or cleanup obligations and other damages under applicable environmental laws. For example, we have obligations to indemnify the buyers of the former explosives business and automotive ignition systems business of Dynamit Nobel for certain environmental matters. Under such sale agreements, these indemnities are not limited as to amount. Furthermore, we have an obligation to indemnify the buyer of our former manufacturing sites at Troisdorf, Germany, for which we have reserved approximately $12.6 million as of December 31, 2005, and Greenville, South Carolina where there has been a discovery of groundwater and soil contamination. We may not have adequate insurance coverage or cash flows to make such indemnity payments. Such payments may be costly and may adversely affect our financial condition and results of operations.

Product Liability—Due to the nature of our business and products, we may be liable for damages arising out of product liability claims.

The sale of our products involves the risk of product liability claims. For example, some of the chemicals or substances that are used in our businesses, such as arsenic pentoxide, have been alleged to represent potentially significant health and safety concerns. Class action suits had been filed in Louisiana, Florida and Arkansas, for example, naming one of our subsidiaries and a number of competitors of our Timber Treatment Chemicals business line in our Performance Additives segment, as well as treaters and retailers, as defendants. In addition, our subsidiary has been named as a defendant in personal injury suits in several jurisdictions with retailers and treaters named as other defendants. Furthermore, there are other similar suits, including putative class actions, pending against retailers, treaters and other formulators to which we may be eventually named as a defendant. These suits allege, among other things, product liability claims in connection with the use of timber products treated with CCA, which utilizes arsenic pentoxide as a raw material. In addition, a subsidiary in our Advanced Ceramics segment has been named as a defendant in several product liability lawsuits in Europe relating to broken artificial hip joints, which allege negligent manufacturing by our subsidiary of ceramic components used in the production of artificial hip joints. Further, a subsidiary in our Specialty Chemicals segment has been named as a defendant in several lawsuits in the United States regarding exposure to solvents and other chemicals contained in some of our products. We are unable to estimate our exposure, if any, to these lawsuits at this time.

We may be subject to future claims with regard to these suits or others like them and we may not be able to avoid significant product liability exposure. A successful product liability claim or series of claims against us for which we are not otherwise indemnified or insured could materially increase our operating costs or prevent such operating subsidiary from satisfying its financial obligations. For example, for policies renewed on or after November 2002, our insurers excluded CCA from our insurance coverage under our general liability policies. We may not have sufficient cash flow from operations or assets to pay a judgment resulting from a product liability claim, if any, for which there is no or inadequate insurance coverage. Any such judgment could materially increase our operating costs or prevent such operating subsidiary from satisfying its financial obligations.

36

Product Liability—Due to the nature of our business and products, we may be liable for damages arising out of certain indemnity claims.

We may be subject to indemnity claims for product liability lawsuits relating to products we have sold. For example, our Timber Treatment Chemicals business has entered into indemnity agreements with various customers who purchased CCA-based wood protection products. Pursuant to those agreements, one of our subsidiaries agreed to defend and hold harmless those customers for certain causes of action, based on domestic mammalian, and in some cases, human toxicity, caused by our CCA-based wood protection products, subject to certain conditions. Our Timber Treatment Chemicals business, and several of our customers were named as defendants in several suits, including putative class actions, relating to CCA-based wood protection products. Our Timber Treatment Chemicals business has received and may in the future receive claims for indemnity from customers in connection with litigation relating to CCA-based wood protection products and may be required to pay indemnity claims under such agreements to one or more of its customers. If our Timber Treatment Chemicals business is required to pay one or more indemnity claims, insurance or indemnity arrangements from Degussa (the successor to Laporte, from which the specialty chemicals business lines that formed Rockwood in the KKR Acquisition were acquired) may not cover such claims and, if not, our subsidiary may not have sufficient free cash flow to pay such claims. We are unable to estimate our exposure, if any, to these claims and lawsuits at this time.

In addition, our Specialty Chemicals segment’s subsidiary that formerly manufactured insulating glass sealants has been named as a defendant in several product liability lawsuits relating to alleged negligent manufacturing of these sealants. Pursuant to the sale and purchase agreement with respect to the divested business, one of our Specialty Chemicals’ subsidiaries may be required to pay indemnity claims for a limited number of years. If such subsidiary is required to pay indemnity claims, our insurance may not cover such claims and, if not, our subsidiary may not have sufficient cash flow to pay such claims. One or more of these claims could adversely affect our financial condition or results of operations.

Cyclicality—Downturns in cyclical industries and general economic conditions could adversely affect our profitability.

Our products are used in certain industries that are cyclical in nature, such as the automotive, data and communications and electronics industries. In addition, sales to the construction market are driven by trends in commercial and residential construction, housing starts and trends in residential repair and remodeling. Downturns in one or more of these industries could severely reduce demand for our products. For example, the telecommunications market has experienced a similar downturn, which affected the results of operations of our Specialty Compounds segment, and in recent years the semiconductor market experienced a severe downturn, which affected the results of operations of our Electronics segment in prior years.

In addition, downturns in general economic conditions, whether in a particular region or globally, could reduce demand for our products. An economic downturn in one or more of the markets or geographic regions in which we sell our products may result in a decline in our net sales.

Pharmaceutical Industry—We may not be able to renew our contracts with Groupe Novasep’s pharmaceutical customers due to their manufacturing strategy, which may adversely affect our results of operations.

Net sales of pharmaceutical intermediates or active ingredients by our Groupe Novasep segment, which accounted for the majority of our 2005 Groupe Novasep net sales of $379.1 million, may be adversely impacted by the manufacturing strategy of our customers in the pharmaceutical industry. Pharmaceutical companies may establish back-up production facilities through a second supplier or manufacture these intermediates on their own if they have hazardous chemical production expertise in-house or are willing to make capital investments. Consequently, while we typically enter into long-term, requirement-based supply contracts with our pharmaceutical customers, we may not be able to renew these contracts upon expiration.

FDA Regulation—Some of our manufacturing processes and facilities, pharmaceutical customers and medical device customers are subject to regulation by the FDA or similar foreign agencies. These requirements could adversely affect our results of operations.

The manufacturing processes and facilities of our Novasep Synthesis business line of our Groupe Novasep segment, which specializes in commercial production of pharmaceutical intermediates, are subject to regulatory requirements of the FDA, including current Good Manufacturing Practice regulations or other applicable foreign regulatory agencies such as the central European agency for medicines. In addition, certain lithium compounds manufactured by our Fine Chemicals business line of our Specialty Chemicals segment are also subject to FDA regulation. Furthermore, the manufacture and supply of ceramic-on-ceramic ball head and liner components for hip joint prostheses systems by our Advanced Ceramics segment may also be subject to the FDA’s Quality System Regulation, which imposes current Good Manufacturing Practice requirements on the manufacture of medical devices.

37

Pharmaceutical customers of our Groupe Novasep segment to whom we supply our pharmaceutical intermediates and medical device customers of our Advanced Ceramics segment to whom we supply our ceramic-on-ceramic ball head and liner components are subject to FDA regulation, including premarket approval of their products and post market compliance requirements. The FDA may take three years or longer to grant premarket approval, if at all. Once approved, our customers’ pharmaceutical products and total hip prostheses systems may be withdrawn from the market either voluntarily by our customers or as a result of the FDA’s or a foreign equivalent’s withdrawal of marketing approval or removal of such products for a number of reasons including safety, current Good Manufacturing Practice or Quality System Regulation problems with our products or our customers’ final products. These factors relating to our customers in the pharmaceutical industry and medical devices industry could significantly limit our net sales generated by our Groupe Novasep segment and Advanced Ceramics segment, respectively, and may have a material adverse effect on our financial condition and results of operations.

Regulatory requirements of the FDA are complex. Any failure to comply with them could subject us and/or our customers to fines, injunctions, civil penalties, lawsuits, recall or seizure of products, total or partial suspension of production, denial of government approvals, withdrawal of marketing approvals and criminal prosecution. Any of these actions could adversely impact our net sales, undermine goodwill established with our customers, damage commercial prospects for our products and materially adversely affect our results of operations.

Competition—Our industry is highly competitive. The end-use markets in which we compete are also highly competitive. This competition may adversely affect our results of operations.

We face significant competition from major international producers as well as smaller regional competitors. Our most significant competitors include major chemicals and materials manufacturers and diversified companies, a number of which have revenues and capital resources exceeding ours.

In addition, within the end-use markets in which we compete, competition between products is intense. Substitute products also exist for many of our products. Therefore, we face substantial risk that certain events, such as new product development by our competitors, changing customer needs, production advances for competing products, price changes in raw materials, our failure to secure patents or the expiration of patents, could result in declining demand for our products as our customers switch to substitute products or undertake manufacturing of such products on their own. If we are unable to develop and produce or market our products to effectively compete against our competitors, our results of operations may materially suffer.

We believe that our customers are increasingly looking for strong, long-term relationships with a few key suppliers that help them improve product performance, reduce costs, or support new product development. To satisfy these growing customer requirements, our competitors have been consolidating within product lines through mergers and acquisitions. We may also need to invest and spend more on research and development and marketing costs to strengthen existing customer relationships, as well as attract new customers. As a result, our substantial debt level could limit our flexibility to react to these industry trends and our ability to remain competitive.

Product Innovation—If we are not able to continue our technological innovation and successful commercial introduction of new products, our profitability could be adversely affected.

Our industries and the end-use markets into which we sell our products experience periodic technological change and product improvement. Manufacturers periodically introduce new generations of products or require new technological capacity to develop customized products. Our future growth will depend on our ability to gauge the direction of the commercial and technological progress in all key end-use markets and upon our ability to fund and successfully develop, manufacture and market products in such changing end-use markets. We will have to continue to identify, develop and market innovative products on a timely basis to replace or enhance existing products in order to maintain our profit margins and our competitive position. We may not be successful in developing new products and/or technology, either alone or with third parties, or licensing intellectual property rights from third parties on a commercially competitive basis. Our new products may not be accepted by our customers. If we fail to keep pace with the evolving technological innovations in our end-use markets on a competitive basis, our business, financial condition and results of operations could be adversely affected.

Dependence on Intellectual Property—If our intellectual property were copied by competitors, or if they were to develop similar intellectual property independently, our results of operations could be negatively affected.

Our success depends to a significant degree upon our ability to protect and preserve our intellectual property rights, which rights we own or use pursuant to licenses granted to us by third parties. The confidentiality and patent assignment agreements we enter into with most of our key employees and third parties to protect the confidentiality, ownership and use of intellectual property may be breached, may not be enforceable, or may provide for joint ownership or ownership by a third party. In addition, we may not have adequate remedies for a breach by the other party, which could adversely affect our intellectual property rights.

38

The use of our intellectual property rights or intellectual property similar to ours by others or our failure to protect such rights could reduce or eliminate any competitive advantage we have developed, adversely affecting our net sales. If we must sue to protect, defend or enforce our intellectual property rights, any suits or proceedings could result in significant costs and diversion of company resources and management attention, and we may not prevail in such action. In addition, when our patents expire, competitors or new market entrants may manufacture products substantially similar to our products previously protected by a patent. For example, our patent in ACQ technology expires in mid-2007.

We conduct research and development activities with third parties and license certain intellectual property rights from third parties and we plan to continue to do so in the future. For example, in our Timber Treatment Chemicals business, we developed the technology to produce ACQ pursuant to a license agreement with Domtar Inc. and through the acquisition of the Kemwood business from Kemira OY. We endeavor to license or otherwise obtain intellectual property rights on terms favorable to us. However, we may not be able to license or otherwise obtain intellectual property rights on such terms or at all. Our inability to license or otherwise obtain such intellectual property rights could have a material adverse effect on our ability to create a competitive advantage and create innovative solutions for our customers, which will adversely affect our net sales and our relationships with our customers.

The steps we take to protect our intellectual property may not provide us with any competitive advantage and may be challenged by third parties. We have been and currently are subject to oppositions of our patents and trademarks by third parties before regulatory bodies in certain jurisdictions. Our failure to defend these patents or registered trademarks may limit our ability to protect the intellectual property rights that these applications were intended to cover. In addition, a failure to obtain and defend our trademark registrations may impede our marketing and branding efforts and competitive position. A failure to protect our intellectual property rights could have a material adverse effect on demand for our products and our net sales.

Risk of Intellectual Property Litigation—Our products or processes may infringe the intellectual property rights of others, which may cause us to pay unexpected litigation costs or damages or prevent us from selling our products.

Although it is our intention to avoid infringing or otherwise violating the intellectual property rights of others, our processes and products may infringe or otherwise violate the intellectual property rights of others. We may be subject to legal proceedings and claims, including claims of alleged infringement by us or our licensees of the patents, trademarks and other intellectual property rights of third parties. Intellectual property litigation is expensive and time-consuming, regardless of the merits of any claim, and could divert our management’s attention from operating our businesses.

If we were to discover or be notified that our processes or products potentially infringe or otherwise violate the intellectual property rights of others, we may need to obtain licenses from these parties or substantially re-engineer our products and processes in order to avoid infringement. We might not be able to obtain the necessary licenses on acceptable terms, or at all, or be able to re-engineer our products successfully. Moreover, if we are sued for infringement and lose the suit, we could be required to pay substantial damages and/or be enjoined from using or selling the infringing products or technology. Any of the foregoing could cause us to incur significant costs and prevent us from selling our products.

International Operations—As a global business, we are exposed to local business risks in different countries which could have a material adverse effect on our financial condition or results of operations and the value of our common stock.

We have significant operations in many countries, including manufacturing facilities, research and development facilities, sales personnel and customer support operations. Currently, we operate, or others operate on our behalf, facilities in countries such as Brazil, Chile, China, Czech Republic, Malaysia, Poland, Portugal, Singapore, South Africa, South Korea, Taiwan and Turkey. Of our total net sales in 2005 of $3,121.2 million, approximately 67% were generated by shipments to countries outside North America. Our operations are affected directly and indirectly by global regulatory, economic and political conditions, including:

•                  new and different legal and regulatory requirements in local jurisdictions;

•                  managing and obtaining support and distribution for local operations;

•                  increased costs of, and availability of, transportation or shipping;

•                  credit risk and financial conditions of local customers and distributors;

•                  potential difficulties in protecting intellectual property;

•                  risk of nationalization of private enterprises by foreign governments;

•                  potential imposition of restrictions on investments;

•                  potentially adverse tax consequences, including imposition or increase of withholding and other taxes on remittances and other payments by subsidiaries;

39

•                  capital controls; and

•                  local political, economic and social conditions, including the possibility of hyperinflationary conditions and political instability in certain countries.

In addition, our facilities may be targets of terrorist activities that could result in full or partial disruption of the activities of such facilities.

Furthermore, our subsidiaries are subject to the export controls and economic embargo rules and regulations of the United States, violations of which may carry substantial penalties. These regulations limit the ability of our subsidiaries to market, sell, distribute or otherwise transfer their products or technology to prohibited countries or persons. Failure to comply with these regulations could subject our subsidiaries to fines, enforcement actions and/or have an adverse affect on our reputation and the value of our common stock.

We may not succeed in developing and implementing policies and strategies to counter the foregoing factors effectively in each location where we do business. Our failure to do so could limit our ability to sell products, compete or receive payments for products sold in such locations.

Retention of Key Personnel—If we lose certain key personnel or are unable to hire additional qualified personnel, we may not be able to execute our business strategy.

Our success depends, in part, upon the continued services of our highly skilled personnel involved in management, research, production, sales and distribution, and, in particular, upon the efforts and abilities of our executive officers and key employees. Although we believe that we are adequately staffed in key positions and that we will be successful in retaining key personnel, we may not be able to retain such personnel on acceptable terms or at all. Furthermore, if we lose the service of any executive officers or key employees, we may not be able to execute our business strategy. We do not have key-person life insurance covering any of our employees.

Relations with Employees—We are subject to stringent labor and employment laws in certain jurisdictions in which we operate, and our relationship with our employees could deteriorate, which could adversely impact our operations.

A majority of our full-time employees are employed outside the United States, particularly in Germany where many of our Dynamit Nobel businesses are located. In certain jurisdictions where we operate, particularly in Germany, labor and employment laws are relatively stringent and, in many cases, grant significant job protection to certain employees, including rights on termination of employment. In addition, in certain countries where we operate, including Germany, our employees are members of unions or are represented by a works council as required by law. We are often required to consult and seek the consent or advice of these unions and/or respective works’ councils. These regulations and laws coupled with the requirement to consult with the relevant unions or works’ councils could significantly limit our flexibility in managing costs and responding to market changes.

Furthermore, with respect to our employees that are subject to collective bargaining arrangements or similar arrangements (approximately 29% of our full-time employees as of December 31, 2005), we may not be able to negotiate labor agreements on satisfactory terms and actions by our employees may disrupt our business. If these workers were to engage in a strike, work stoppage or other slowdown, we could experience a significant disruption of our operations and/or higher ongoing labor costs. In addition, if our other employees were to become unionized, we could experience a significant disruption of our operations and/or higher ongoing labor costs.

40

Tax Liabilities—If mg technologies ag or Degussa UK Holdings, Ltd. fail to satisfy their contractual obligations, we may be subject to increased tax exposure resulting from pre-acquisition periods.

Under the terms of the certain purchase agreements, third party sellers have agreed to substantially indemnify us for tax liabilities pertaining to the pre-acquisition periods. To the extent such companies fail to indemnify or satisfy their obligations, or if any amount is not covered by the terms of the indemnity, we would be required to record an adjustment to goodwill to satisfy any such liabilities and could be negatively impacted in future periods through incremental outlays of cash tax.

Anticipated Capital Expenditures—Our required capital expenditures may exceed our estimates.

Our capital expenditures, excluding capital leases, for the year ended December 31, 2005 were $199.2 million, which consisted of expenditures to maintain and improve existing equipment and substantial investments in new equipment. For 2006, we expect capital expenditures to be comparable to 2005. Future capital expenditures may be significantly higher, depending on the investment requirements of each of our business lines. Future capital expenditures may also vary substantially if we are required to undertake certain actions to compete with new technologies in our industry. We may not have the capital necessary to undertake these capital investments. If we are unable to do so, we may not be able to effectively compete in some of our markets.

Control—A conflict may arise between our interests and those of KKR.

Affiliates of KKR own approximately 50.9% of our common stock on an undiluted basis. In addition, representatives of KKR occupy four of the nine seats on our board of directors. As a result, affiliates of KKR have substantial influence over our decisions to enter into any corporate transaction and have the ability to prevent any transaction that requires the approval of the stockholders regardless of whether or not other stockholders believe that any such transactions are in their own best interests. Additionally, KKR is in the business of making investments in companies and may from time to time acquire and hold interests in businesses that compete directly or indirectly with us. They may also pursue acquisition opportunities that may be complementary to our business, and as a result, those acquisition opportunities may not be available to us. So long as affiliates of KKR continue to hold a majority of our outstanding common stock, they will be entitled to nominate a majority of our board of directors, and will have the ability to control the vote in any election of directors even though KKR does not currently occupy a majority of the seats on our board of directors. See Item 12, “Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters” and Item 13, “Certain Relationships and Related Transactions.”

We are a “controlled company” within the meaning of the New York Stock Exchange rules and, as a result, will qualify for, and intend to rely on, exemptions from certain corporate governance requirements.

Affiliates of KKR continue to control a majority of our outstanding common stock. As a result, we are a “controlled company” within the meaning of the New York Stock Exchange corporate governance standards. Under the New York Stock Exchange rules, a company of which more than 50% of the voting power is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain New York Stock Exchange corporate governance requirements, including:

•                  the requirement that a majority of the board of directors consist of independent directors;

•                  the requirement that we have a nominating/corporate governance committee that is composed entirely of independent directors;

•                  the requirement that we have a compensation committee that is composed entirely of independent directors; and

•                  the requirement for an annual performance evaluation of the nominating/corporate governance and compensation committees.

We utilize these exemptions, and as a result, we do not have a majority of independent directors and our nominating/corporate governance and compensation committees do not consist entirely of independent directors. Accordingly, you do not have the same protections afforded to stockholders of companies that are subject to all of the New York Stock Exchange corporate governance requirements.

Effectiveness of Internal Controls - If we are unable to implement the requirements of Section 404 in a timely manner or if we conclude our internal controls are not effective in other areas, we may be subject to sanctions or investigation by regulatory authorities and incur additional compliance costs and the financial markets may react negatively.

We are currently performing the system and process evaluation of our internal controls over financial reporting in order to allow management to report on, and our independent auditors to attest to, our internal controls over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act of 2002, which we refer to as Section 404. The requirements of Section 404 will initially apply to us in connection with our annual report on Form 10-K for the year ended December 31, 2006. In connection with our preliminary evaluation, we have identified areas of internal controls that may need improvement, such as internal controls related to the segregation of duties at certain smaller locations, system access and user security profiles, operating policies and procedures and in each case particularly with respect to newly acquired businesses. We have begun the testing necessary to permit the management certification and auditor attestation required to comply with Section 404 in 2006. As we complete the evaluation and testing required by Section 404, we may identify conditions that may be categorized as significant deficiencies or material weaknesses in the future.

41

If we are not able to implement the requirements of Section 404 in a timely manner, management will not be able to certify as to the effectiveness of our internal control over financial reporting and we may be subject to sanctions or investigation by regulatory authorities, such as the SEC.

Item 2. Properties.

We are an international business, serving customers worldwide. To service our customers efficiently, we maintain over 100 manufacturing facilities in 25 countries around the world with a strategy of global, regional and local manufacturing to optimize our service offering and minimize production cost to our customers.

We are dedicated to maintaining updated and technologically advanced manufacturing facilities. To that end, we made capital expenditures, excluding capital leases, of $199.2 million, $112.8 million and $34.3 million, for the periods ended December 31, 2005, 2004 and 2003, respectively, to expand, upgrade and maintain our manufacturing capabilities. Rockwood’s capital expenditures in 2005 consisted primarily of replacements of worn, obsolete or damaged equipment as well as investments in new equipment, mostly for our Advanced Ceramics, Specialty Chemicals and Groupe Novasep segments. Capital expenditures in our Advanced Ceramics segment primarily related to expanding our medical products production facility. In our Specialty Chemicals segment, we made a significant investment in connection with Lithium production. Capital expenditures also consisted of expansion of current Good Manufacturing Practice production lines and new equipment relating to multi-column chromatography in our Groupe Novasep segment. The 2004 amount includes the capital expenditures during the five months of operations for the Dynamit Nobel businesses, including Advanced Ceramics’ major expansion at its Marktredwitz, Germany facility related to hip replacement products. The 2003 amount only includes the historic Rockwood businesses. During this three-year period, we constructed new plants for our Timber Treatment Chemicals business line of our Performance Additives segment in Harrisburg, North Carolina, and for our wafer reclaim business line of our Electronics segment in Prescott, Arizona and upgraded our wafer reclaim facility and operations in Greasque, France. For the year ended December 31, 2003 and the years ended September 30, 2002 and 2001, the Dynamit Nobel businesses made capital expenditures of $122.0 million, $112.0 million and $125.1 million, respectively, which included expansion of our current Good Manufacturing Practice production lines and new equipment relating to multi-column chromatography in our Groupe Novasep segment, expansion of our titanium dioxide capacity for our Titanium Dioxide Pigments segment and capacity expansion for our Advanced Ceramics segment. We believe that our plants and facilities are maintained in good condition and are adequate for our present and currently expected future needs.

Item 3. Legal Proceedings.

We are involved in legal proceedings from time to time in the ordinary course of our business, including with respect to product liability, intellectual property and environmental matters. In addition, we may be required to make indemnity payments in connection with certain product liability and environmental claims. See Item 1, “Business,” and Item 1A, “Risk Factors,” “Environmental Indemnities—We may be subject to environmental indemnity claims relating to properties we have divested”; “Product Liability—Due to the nature of our business and products, we may be liable for damages arising out of product liability claims”; and “Product Liability—Due to the nature of our business and products, we may be liable for damages arising out of certain indemnity claims.” However, we do not believe that there is any other individual, governmental, legal proceeding or arbitration that is likely to have a material adverse effect on our business, results of operations, cash flows or financial condition.

Market Information; Holders; and Dividends

The Company’s common stock is traded on the New York Stock Exchange under the ticker symbol ROC. As of March 21, 2006, there were 114 holders of record of the Company’s common stock.

High and low sales prices for the Company’s common stock from August 17, 2005, the date it began trading, through the third quarter ended September 30, 2005, were $20.37 and $17.55, respectively.

Rockwood Holdings, Inc.’s operations are conducted through its subsidiaries and its ability to make payments on any obligations it may have is dependent on the earnings and the distribution of funds from its subsidiaries. As a result, we are dependent upon cash dividends and distributions and other transfers from our subsidiaries to make dividend payments on our common stock. The amounts available to us to pay cash dividends are restricted by our subsidiaries’ debt agreements. Under Group’s senior secured credit facilities and indentures governing the 2011 notes and 2014 notes, Group is generally restricted from making dividends or other distributions to us. Any decision to declare and pay dividends in the future will be made at the discretion of our board of directors and will depend on, among other things, our results of operations, cash requirements, financial condition, contractual restrictions and other factors that our board of directors may deem relevant (see further discussion in liquidity section of Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”).

There were no repurchases of any of the Company’s common stock by or on behalf of the Company during the fourth quarter of 2005 and no sales of unregistered equity securities by the Company during the fiscal year ended December 31, 2005.
