Overview

Nalco Holding Company is the global leader in water, energy, air and process technologies and services that deliver savings for customers and improve the
environment. Our principal executive offices are located at 1601 West Diehl Road, Naperville, Illinois, 60563.

On August 31, 2003, Nalco
Holdings LLC, our subsidiary and a company formed by The Blackstone Group, Apollo Management, L.P. and GS Capital Partners (the Sponsors), entered into a stock purchase agreement pursuant to which it agreed to purchase all of the
outstanding shares of capital stock of Ondeo Nalco Company (which is now known as Nalco Company) and the Nalco International SAS Subsidiaries, which had been operated as a single business unit, from subsidiaries of Suez S.A. (Suez or
Seller). The Transactions closed on November 4, 2003. In this report, we refer to this acquisition as the Acquisition, and the term Transactions means, collectively, the Acquisition and the related financings
to fund the Acquisition.

All references in this report to Nalco,  the Company, we, our, and
us mean, unless the context indicates otherwise, (1) Nalco Holding Company and its subsidiaries and affiliates on a consolidated basis, (2) the Predecessor, and (3) the Successor. In addition, when the context so requires,
we use the term Predecessor to refer to the historical operations of the Predecessor prior to the Acquisition and Successor to refer to our historical operations following the Acquisition.

Our programs and services are used in water treatment applications to prevent corrosion, contamination and the buildup of harmful deposits and in production
processes to enhance process efficiency, extend asset life, improve our customers end products, and enhance air quality. We also help our customers reduce energy, water and other natural resource consumption, minimizing environmental releases
while improving their bottom line. Together our comprehensive solutions contribute to the sustainable development of customer operations.

Through our sales, service, research and marketing teams of more than 7,000 technically trained professionals, we serve nearly 50,000 customer locations in a broad range of end markets, including aerospace, chemical, pharmaceutical,
petroleum, steel, power, food and beverage, medium and light manufacturing, marine and pulp and papermaking industries as well as institutions such as hospitals, universities and hotels. We focus on providing our customers with sustainable,
technologically advanced, engineered solutions and services.

We have an established global presence with more than 11,500 employees working
in more than 150 countries, supported by a comprehensive network of manufacturing facilities, sales offices and research centers. This global presence provides a competitive advantage by enabling us to offer a high level of service to our local,
regional and multinational customers.

Our Competitive Strengths

Our Company has benefited from the following competitive strengths:

Leading Market
Positions.    We are the #1 provider of water treatment services to industrial and institutional end markets. We are also a leading provider of integrated water treatment and process

improvement services, maintaining the #1 position in the petroleum and petrochemical markets and a #3 position in the pulp and paper market. We believe that our leading positions across our
primary markets provide a competitive advantage in retaining existing business and competing for new business. Broader water markets, including additional industrial water application types and the full scope of municipal and agricultural water
markets, are estimated by various sources to be several hundred billion dollars in total size.

Diverse Customers and Industries
Served.    We provide products and services to nearly 50,000 customer locations around the world, a reduced number from just a few years ago in part due to the impact of the economic recession on customer facility
closures, but largely due to Nalco actions to turn over or sell large numbers of low-dollar accounts to distributors, agents or other channels to market.

In 2009, no single customer accounted for more than 4% of our net sales. Our business is also diversified geographically. In 2009, 48% of our net sales were to customer destinations in North America, 26%
in Europe, Africa and the Middle East, 10% in Latin America and 16% in the Asia/Pacific region. We believe this diversification helps to lessen the impact of volatility from any one customer, industry or geographic area.

Global Reach.    We have a direct sales and marketing presence in more than 150 countries across six continents. This
enables us to provide a high level of service to local, regional and multinational customers. We believe our global presence offers us a competitive advantage to meet the global needs of our multinational customers, which are increasingly seeking
single-source suppliers. This positions us to extend our reach to higher growth markets. Our geographic diversity also mitigates the potential impact of volatility in any individual country or region. In 2009, we derived approximately $2,228
million, or 59% of our net sales, from customer destinations outside the United States.

World Class Sales
Team.    Through the expertise of our more than 7,000 sales engineers and service technicians, we provide our customers with relevant industry knowledge and experience in order to solve technically challenging and dynamic
problems. Our team of experts has significant experience, with more than 40% of our approximately 2,000-person North American sales team having more than ten years of service with our Company. We believe this contributes significantly to the number
and strength of relationships with our customers. We also invest heavily in recruiting and continuously training our sales professionals. For example, new hires spend more than half of their first year on training. Sales and marketing expense was
$880.2 million, $972.4 million, and $915.1 million for the years 2009, 2008 and 2007, respectively. Of those amounts, approximately 90% represented the cost of our sales force and related expenses during these time periods.

Integrated Technology, Sales and Service.    We combine on-site service, innovative technology and engineering excellence
to create value for our customers. Our technical sales professionals identify problems and opportunities at the customers plant and our research teams then work to develop effective solutions to these needs, often working jointly with our
customers. Many of our customers specify our formulations into their processes and products. This approach has led to over 4,700 unique formulations, the development of more than 1,800 active patents worldwide and a high degree of customer loyalty.

Stable and Significant Cash Flow Generation.    We have produced consistent cash flows and maintained high
margins over a sustained period of time. We attribute this to (1) the diversity of our revenues, (2) the service nature of our business, (3) the high value we offer our customers, including through patented technology, (4) the
strength of our customer relationships, (5) our limited dependency on any single raw material and (6) our low capital expenditures relative to our net sales.

Deep Management Team.    Our senior management team consists of professionals with significant experience within our Company and the water treatment and industrial
process improvement industry. J. Erik Fyrwald, a veteran of 28 years with E.I. du Pont de Nemours and Company, most recently as Group Vice President of its Agriculture and Nutrition Division, joined Nalco in 2008 as our Chairman,

President and Chief Executive Officer. Bradley J. Bell, former Chief Financial Officer of Rohm and Haas Company, is our Executive Vice President and Chief Financial Officer. Our Energy Services
and European divisions are led by Steve M. Taylor and David Johnson, respectively, both long-time Nalco veterans. Additionally, established industry veterans who joined the Company in 2008, David E. Flitman and Eric G. Melin, lead our Water and
Process Services and Asia/Pacific divisions, respectively.

Our Business Strategy

We have established a recently modified six-part business strategy designed to focus internal resources on the issues and opportunities with the greatest
opportunity to improve our performance for many years to come.

1.Improve Safety.

Given our exposure to critical processes through a wide range of industrial applications, we put a strong focus on our ability to ensure
that we maintain the safety of our customers and our employees. In 2009, we maintained our Total Recordable Incident Rate at top quartile levels, recording 0.56 incidents per 100 workers while making significant gains in reducing total and severe
vehicle accident rates. Improving our safety performance remains a critical objective of senior management.

2.Generate Focused, Profitable Growth.

We have historically experienced sales
growth in excess of industrial production growth in our core markets. We are now pursuing a strategy designed to double our sales growth rate to a 6- to 8-percent range as a run rate by the end of 2011 from a historic growth rate of 3 to 4 percent
that was calculated as excluding price increases designed to only offset higher raw material costs. The key elements of our sales growth strategy are:



| |  |  | Pursue High-Growth Geographies.    We intend to continue to focus on high-growth markets and segments, implementing a
BRIC+ strategy that prioritizes resources  particularly hiring and training sales engineers  to areas with the greatest growth potential. Over the long term, we believe Brazil, Russia, India and China are among the countries
offering the highest growth potential. Modernization in those markets is expected to drive water treatment growth at a rate faster than industrial production. China and India were our top growth priorities in 2009, and we added 180 employees in
those countries last year. The + part of the BRIC+ strategy is focused on markets with emerging or expanding oil and gas production, refining and petrochemical operations, including the Caspian, Middle East and West Africa. During 2009,
Steve Taylor, President of Energy Services, relocated to Dubai to help drive success in these regions.

| |  |  | Maintain Technological Leadership.    We invest to develop new technologies and products through a focused commitment
to technology, research and development. The evolution of our existing products and the development of new technologies have historically allowed us to sustain and enhance the profitability of our business and further penetrate our target markets,
including our existing customer base. For example, over the past 15 years we have developed several generations of our TRASAR automated feed and control technology for cooling water treatment programs. We launched the latest generation of this
technology, our 3D TRASAR cooling water program, in 2004. In 2007, we extended our reach with this platform by introducing 3D TRASAR Technology for Reverse Osmosis membrane control. In 2009, we further expanded on this breakthrough technology
concept by introducing 3D TRASAR Technology for Boilers and the Nalco Corrosion Stress Monitor for pre-boiler corrosion control in many industrial markets. Our engineers will continue to work closely with our customers in an effort to identify
new product opportunities, jointly develop new technologies and accelerate penetration of this important automation offering.

| |  |  | Pursue High-Growth Industry Segments.While we have shown the ability to exceed market growth rates even in many
mature markets through innovative technology and advanced engineering, monitoring and control services, we believe that selecting the right industries on
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | which to focus resources helps us exceed underlying market growth rates. In the late 1990s, we decided to disproportionately invest in research, development and training resources to support fast
growth in the deepwater oil production industry. As a result, we continue to exceed our average market share in our overall Energy Services business capture in deepwater and ultra-deepwater (UDW) sectors. In addition to substantial investments in
internally developed technology, we continue to pursue technology ventures and acquisitions that expand the expertise we can bring to customers in growing segments. During 2008, we acquired TIORCO, Inc. to add reservoir-engineering expertise to our
enhanced oil recovery offering, and GL OneSource to expand our natural gas production maximization offering. We also bought Data Mobility Systems to expand our engineered modeling capabilities to optimize performance of various customer processes
and Veranum Tempus Engenharia to expand our indoor climate control capabilities. In 2009, we purchased Crossbow Water, expanding our capabilities in water pre-treatment technologies and services in the Midwest region of the United States.

| |  |  | Build Upon Our Customer Base.    We seek to strengthen our position with our existing customer base as well as pursue
new customers by continuing to serve as the leading global provider of fully integrated water treatment services and industrial process solutions, while building an air quality control platform. An essential element of our strategy is to continue
integrating our sales and technical staff into our customers daily operations and process planning. Historically, this strategy has allowed us to expand our service and product offerings with existing customers and has led to the development
of new technologies. We continually seek to add value for our customers by identifying those services, products and equipment that will enhance their profitability through reduced costs, improved yields and decreased capital spending 
generally with substantial environmental benefits that include water use reduction, improved water quality, energy efficiency, waste reductions and air quality improvements.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Benefit from our Global Resource Advantage.    As one of a small number of companies that can provide turnkey water
management solutions on a global basis, we seek to leverage our relationships with multinational companies by servicing them globally. We expect to benefit significantly as larger customers further consolidate their supplier base and increase their
reliance on full service providers, such as our Company.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

3.Increase Sales
Time.

With more than 7,000 sales engineers and services technicians spread around the world, we must be vigilant in ensuring
that our sales teams spend as much of their time as possible in front of customers identifying new performance improvement opportunities, creating solutions and selling new business. During 2009, we launched a Commercial Excellence project designed
to free up sales engineers to focus on the best service and sales initiatives  in large part by reducing the amount of time spent on administrative tasks and in non-value-added travel. We began implementation of this project in some parts of
the Company in 2009 and will extend this effort fully  with improved performance metrics to ensure that gains are lasting  during 2010.

4.Continue to Reduce Costs.

Our ongoing comprehensive cost productivity plan
yielded savings in 2009 of $122 million, surpassing our increased annual goal of $100 million in savings. In addition, we gained $38 million of one-time expense reductions to address tight economic conditions. These one-time cost savings are largely
expected to return to our operating expenses and costs of goods sold in 2010. Through work process redesign and other cost control initiatives, we achieved average annual savings of $84 million over the five years prior to 2009, during which our
historic annual target was $75 million. We expect our cost reduction plan to achieve sustainable efficiencies using our Nalco Seven Steps process improvement methodology and the best of several other productivity improvement approaches. Our
productivity improvement programs include focus on individual spending accountability, team- or department-based efficiency improvements, and mid-sized and larger transformational process improvements. All of these efforts

target greater efficiencies in our sales, marketing, service, supply chain and corporate functions globally. We pay particular attention to ensuring that internal efficiency efforts are developed
with a clear focus on improving customer service levels.

5.Generate Cash Flow.

We believe that there are significant opportunities to generate cash flow. We believe that the capital expenditures required to maintain
our business are low relative to our sales, particularly compared to companies in the chemical industry. We generally expect capital expenditures at or near $120 to $170 million annually, with spending at the higher end of that range occurring if
tied to specific customer contracts. In 2010, we expect to spend $140 to $170 million on capital expenditures, as we make up for projects delayed in 2009 and as we increase sales growth rates. In 2008 and 2009, net capital expenditures were $133.1
million and $102.2 million, respectively. Working capital management remains a source of opportunity for our Company, although significant progress was made in 2009. While management has historically focused on particular components of working
capital, the large increase in raw material costs and commensurate price increases achieved to cover these costs had substantially driven up working capital requirements during the 2004 to 2008 timeframe. Through a new integrated business management
approach, combined with improved Sales and Operations Planning processes, we began to reduce inventories meaningfully, taking 15 days out of Days Investment in Inventory in 2009 alone. During 2009, we also substantially reduced Days Sales
Outstanding to levels last seen at year end prior to 2003. During the year ended December 31, 2009, we used cash flow from operations of $593.8 million for capital expenditures, a small acquisition, common stock dividends, and meaningful debt
payments.

6.Strengthen our Future.

Several elements of our operations are critical to our long-term success, including training and developing our people, developing broader recognition of our
global brand, increasing customer satisfaction through a broader and more thorough implementation of our Six Service Standards approach to customer service management, and development of ever-increasing value from our technology pipeline. All of
these issues attract substantial and ongoing senior leadership attention.

empty PORTA-FEED unit back for cleaning and re-use. Since the introduction of the PORTA-FEED program in 1985, we have eliminated the disposal of over four million chemical drums.

We also understand that it is crucial to all businesses to have the power to monitor and control their chemical treatment programs on an on-going basis in
an efficient and easy-to-use manner. We have developed equipment that works with our innovative TRASAR and 3D TRASAR technology to provide real-time, on-line monitoring of actual chemical levels in a system. Through our TRASAR system, we chemically
bar-code treatment molecules with a fluorescent tracer that reacts to specific light wavelengths. Once in the system, the tracer is optically excited and detected. Our equipment monitors the level of chemicals and continuously makes
automatic adjustments as necessary through chemical injection systems linked to the TRASAR or 3D TRASAR controller. By preventing overfeeding and underfeeding, and eliminating the unnecessary application of chemicals, this real-time, on-line
monitoring capability saves water and energy as well as improves efficiency, reliability and productivity.

We offer integrated UltraTreat
systems that include industrial reverse osmosis systems, water softening equipment, multi-media and carbon filtration and high efficiency filters.

Joint Ventures

During our history, we have entered into general partnerships or joint ventures for limited scope business
opportunities. We have a joint venture with Siemens Water Technologies Inc., Treated Water Outsourcing, to pursue process water treatment outsourcing projects and to supply standard water treatment equipment packages with our chemicals and service
offerings. In June 2004, we entered into a joint venture with Katayama Chemical, Inc., or KCI, for the marketing and sale of our water treatment and process chemicals in Japan. KCI is a leading participant in these markets in Japan and the venture
permits the combination of our broad product portfolio with KCIs strong market presence. This joint venture does not include manufacturing, research and administrative resources, which are provided to the joint venture by the parents. In 2008
we formed a joint venture with Stepan Company operating under the TIORCO brand to globally market custom engineered chemical solutions for increased production of crude oil and gas from existing fields. The joint venture is equally owned and
controlled by Nalco and Stepan. The two partners will capture most of the value generation directly. Additionally, we maintain longstanding partnerships in Saudi Arabia, relating to base-water treatment, and in Spain, relating to oil-free emulsion
polymers.

We will continue to evaluate the potential for partnerships and joint ventures that can assist us in increasing our geographic,
technological and product reach. For example, we continue to evaluate partnerships that will expand our offerings to our middle market customers and that will permit us a more significant local identity in certain Asian countries.

Competition

Water management and process
improvement service companies compete on the basis of their demonstrated value, technical expertise, chemical formulations, consulting services, detection equipment, monitoring services, and dosing and metering equipment. In general, the markets in
which our Company competes are led by a few large companies, with the rest of the market served by smaller entities focusing on more limited geographic regions.

The market for water treatment chemicals is highly fragmented, but is led by our Company. The remainder of the market is comprised of mainly regional and local players, with GE Water Technologies, the
Ashland Hercules Water Technologies business of Ashland Inc., Danaher Corporations ChemTreat business, and Kurita Water Industries Ltd. present in two or more regions. Regional service providers tend to be modestly sized and focus either on a
limited geographic region or a smaller subset of products and services. Collectively, local players have the largest share of the market, but are individually much smaller and tend to focus on servicing local businesses typically requiring less
sophisticated applications.

The largest participants in the energy services sector are our Company, the Baker Petrolite Division of
Baker Hughes Corporation, GE Water Technologies and Champion Technologies, Inc. The remainder of the market consists of smaller, regional niche companies focused on limited geographic areas.

The market for specialty and water treatment chemicals used in the pulp and paper industry is fragmented. The top suppliers of water treatment services to
the pulp and paper industry are our Company, the Ashland Hercules Water Technologies business of Ashland Inc., Kemira Oyj, Akzo Nobel N.V.s EKA Chemicals AB and BASF AGs Paper Chemicals business. The remainder of the market is comprised
of smaller, regional participants.

Research and Development

We benefit from a high quality research and development effort consisting of more than 560 personnel worldwide, more than 250 of whom have Ph.D.s, dedicated to developing new technology and providing
support. Our laboratories, which are located in the United States, the Netherlands, China and Singapore, are involved in the research and development of chemical products and in providing technical support, including chemical analyses of water and
process samples. Research and development spending was $74.6 million, $73.5 million and $65.8 million and for the years ended December 31, 2009, 2008 and 2007, respectively. In recent years, we have received numerous research and development
awards, including a United States Presidential Green Chemistry Achievement Award in 2008 for our 3D TRASAR technology for cooling water.

We
believe that continued research and development activities are critical to maintaining our leadership position within the industry and will provide us with a competitive advantage as we seek additional business with new and existing customers.

Intellectual Property

We
own or have licenses to use a large number of patents relating to a large number of products and processes. We currently have nearly 550 patents in the United States and more than 1,800 worldwide with remaining durations ranging from less than one
year to 20 years. The average remaining duration is approximately 10 years. We also have nearly 300 registered U.S. trademarks covering our products. Our rights under such patents and licenses and trademarks are of significant importance in the
operation of the business. Patents related to our TRASAR and 3D TRASAR technology and trademarks related to Nalco Company, 3D TRASAR and BrightWater are considered material to our business. U.S. and foreign patents protect aspects of our key TRASAR
and 3D TRASAR technology until at least 2024. The Nalco Company, 3D TRASAR and BrightWater trademarks are registered or applied for in all of our key markets, and we anticipate maintaining them indefinitely. We believe that no other patent,
trademark or license is material to our business.

Raw Materials

We purchase more than 7,000 raw materials, with the largest single raw material representing less than 1% of sales, or less than 3% of raw material purchases. The principal raw materials purchased by us
are ordinarily available in adequate quantities from several sources of supply in the United States and foreign countries. While single raw material purchases are not significant to us, we do purchase similar categories of products in many cases.
Four categories of raw material purchases each represented more than 10% of our total North American purchases in a recent analysis: Organics; Monomers; Polymers; and Solvents, Oils and Alcohols. Our raw material purchases also include a variety of
amines, surfactants, biocides, inorganics, salts, packages, bases, defoamers, fatty acids and phosphonates, among many other types of materials. For the years ended December 31, 2009, 2008 and 2007, we purchased direct materials valued at $881
million, $1,265 million and $1,126 million, respectively. In addition to lower costs of materials and reduced sales, inventory reductions contributed to the decline in direct material purchases in 2009. Joint ventures consolidated by us made direct
material purchases valued at $76 million, $88 million and $80 million in the years ended December 31, 2009, 2008 and 2007, respectively.

Employees

As of December 31, 2009, we had approximately 11,590 employees, of whom approximately 4,655 were employed in North America, approximately 2,780 were employed in Europe, the Middle East and Africa,
approximately 1,650 were employed in Latin America and approximately 2,505 were employed in the Pacific region. We consider relations with our employees to be good.

Environmental Matters

Governmental provisions regulating the discharge of materials into
the environment or otherwise relating to the protection of the environment, have had, and will continue to have, an effect on us and on our operations. Under some environmental laws, we may be jointly and severally liable for the costs of
environmental contamination on or emanating from our properties and at off-site locations where we disposed or arranged for the disposal or treatment of regulated materials, and may also incur liability for damages to natural resources. We have made
and continue to make expenditures for projects relating to the environment. We are currently identified as a potentially responsible party at certain contaminated waste disposal sites. We do not anticipate that these matters will result in material
liabilities; however, there can be no assurance that discovery of previously unknown conditions or other circumstances will not require significant expenditures by us.

We do not believe that compliance with individual environmental protection laws and regulations will have a material effect upon our capital expenditures, earnings or competitive position, although there
can be no assurance to that effect. However, increased air and water environmental enforcement in developing countries, implementation of greenhouse gas controls in various regions of the world and requirements on industry to improve environmental
performance through the European Unions Integrated Pollution Prevention and Control directive all are supportive of Nalcos environmental performance improvement/sustainable development business approach. Agency delays in issuing proposed
revisions to the Clean Air Interstate Rule and Clean Air Mercury Rule have temporarily reduced customer interest in the air protection offerings of Nalco Mobotec.

Our capital expenditures for environmental control facilities during 2009 and future periods are not presently expected to be material to us. We believe that any liability that may result from the
resolution of environmental matters for which sufficient information is available to support cost estimates will not have a material adverse effect on our financial position or results of operations. However, we cannot predict the effect on our
financial position of expenditures for aspects of certain matters for which there is insufficient information. In addition, we cannot predict the effect of compliance with environmental laws and regulations with respect to unknown environmental
matters or future environmental requirements on our financial position, results of operations, liquidity or cash flow.

We have been named as
a defendant in multi-party lawsuits based on our claimed involvement in the supply of allegedly hazardous materials. The plaintiffs seek damages for alleged personal injury or the potential of personal injury resulting from exposure to various
chemicals. These matters have had de minimis impact on our business historically, and we do not anticipate that these matters present any material risk to our business or competitive position in the future. Notwithstanding our past
experience, we cannot predict with certainty the outcome of any such tort claims or the involvement we might have in such matters in the future.

We are also subject to a variety of regulations relating to the production and handling of our products, as well as the conduct and condition of our production facilities. We do not believe that these regulatory requirements will have a
material effect on capital expenditures, earnings or competitive position. Chemical registration regulations in the European Union, referred to as REACH, will result in additional costs to us and our competitors. These costs are presently not
anticipated to materially impact earnings or our competitive position and we have developed a program to meet the regulations.

|ITEM 1A. | RISK FACTORS
|-------- | ------------

If we are unable to
respond to the changing needs of a particular industry and to anticipate, respond to or utilize changing technologies and develop new offerings, it could become more difficult for us to respond to our customers needs and cause us to be less
competitive.

We have historically been able to maintain our market positions and margins through continuous innovation of products and
development of new offerings to create value for our customers. Recent innovations and developments that we have relied on include our 3D TRASAR system for controlling and monitoring chemical feed. We may not be successful in continuing to make
similar innovations in the future. Our future operating results will depend to a significant extent on our ability to continue to introduce new products and applications and to develop new offerings that offer distinct value for our customers. Many
of our products may be affected by rapid technological change and new product introductions and enhancements. We expect to continue to enhance our existing products and identify, develop and manufacture new products with improved capabilities and
make improvements in our productivity in order to maintain our competitive position. We intend to devote sizeable resources to the development of new technologically advanced products and systems and to continue to devote a substantial amount of
expenditures to the research and development functions of our business. However, we cannot assure you that:



| |  |  | we will be successful in developing new products or systems or bringing them to market in a timely manner;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | products or technologies developed by others will not render our offerings obsolete or non-competitive;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | the market will accept our innovations;
| | - |  | ---------------------------------------



| |  |  | our competitors will not be able to produce our core non-patented products at a lower cost;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | we will have sufficient resources to research and develop all promising new technologies and products; or
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | significant research and development efforts and expenditures for products will ultimately prove successful.
| | - |  | ------------------------------------------------------------------------------------------------------------

Our ability to anticipate, respond to and utilize changing technologies is crucial because we compete with many companies in each of the markets in which we
operate. For example, we compete with hundreds of companies in the water treatment chemicals market, including our largest global water treatment competitor, GE Water Technologies. Our ability to compete effectively is based on a number of
considerations, such as product and service innovation, product and service quality, distribution capability and price. Moreover, water treatment for industrial customers depends on the particular needs of the industry. For example, the paper
industry requires a specific water quality for bleaching paper; certain industrial boilers require demineralized water; the pharmaceuticals industry requires ultra pure water for processing; and, in the case of municipal services, water treatment
includes clarification for re-use, sludge dewatering and membrane ultra filtration. We may not have sufficient financial resources to respond to the changing needs of a particular industry and to continue to make investments in our business, which
could cause us to become less competitive.

Our substantial leverage could harm our business by limiting our available cash and our
access to additional capital.

As of December 31, 2009, our total consolidated indebtedness was $2,944.1 million and we had $231.6
million of borrowing capacity available under our revolving credit facility, which reflects no outstanding borrowings and reduced availability as a result of $18.4 million in outstanding letters of credit.

##### Table of Contents

Our high degree of leverage could have important consequences for you, including the following:



| |  |  | It may limit our and our subsidiaries ability to obtain additional financing for working capital, capital expenditures, product development, debt
service requirements, acquisitions and general corporate or other purposes on favorable terms or at all;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A substantial portion of our subsidiaries cash flows from operations must be dedicated to the payment of principal and interest on their and our
indebtedness and thus will not be available for other purposes, including operations, capital expenditures and future business opportunities;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | It may limit our ability to adjust to changing market conditions and place us at a competitive disadvantage compared to those of our competitors that
are less highly-leveraged;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | It may restrict our ability to make strategic acquisitions or cause us to make non-strategic divestitures; and
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | We may be more vulnerable than a less leveraged company to a downturn in general economic conditions or in our business, or we may be unable to carry
out capital spending that is important to our growth.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

At December 31, 2009, we had $1,224.1 million of variable rate
debt. A 1% increase in the average interest rate would increase future interest expense by approximately $12.2 million per year.

Despite our current leverage, we may still be able to substantially increase our indebtedness. This could further exacerbate the risks that we and our subsidiaries face.

We and our subsidiaries may be able to substantially increase our indebtedness in the future. The terms of the indentures governing our subsidiaries
notes do not fully prohibit our subsidiaries or us from doing so. Nalco Companys revolving credit facility provides commitments of up to $250.0 million, of which $231.6 million would have been available for future borrowings as of
December 31, 2009, due to $18.4 million in outstanding letters of credit. If new debt is added to our current debt levels, the related risks that we and our subsidiaries now face could intensify.

Our subsidiaries debt agreements contain restrictions that limit our flexibility in operating our business.

Nalco Companys senior credit agreement and the indentures governing our subsidiaries existing notes contain a number of significant covenants
that, among other things, restrict our or our subsidiaries ability to:



| |  |  | incur additional indebtedness;
| | - |  | ------------------------------



| |  |  | pay dividends on or make other distributions or repurchase certain capital stock;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | make certain investments;
| | - |  | -------------------------



| |  |  | enter into certain types of transactions with our affiliates;
| | - |  | -------------------------------------------------------------



| |  |  | pay dividends or other payments by restricted subsidiaries;
| | - |  | -----------------------------------------------------------



| |  |  | use assets as security in other transactions; and
| | - |  | -------------------------------------------------



| |  |  | sell certain assets or merge with or into other companies.
| | - |  | ----------------------------------------------------------

In addition, under the senior credit agreement, Nalco Holdings LLC is required to satisfy and maintain specified financial ratios and tests. Events beyond our control may affect its ability to comply with
those provisions and Nalco Holdings LLC may not be able to meet those ratios and tests. The breach of any of these covenants would result in a default under the senior credit agreement and the lenders could elect to declare all amounts borrowed
under the senior credit agreement, together with accrued interest, to be due and payable and could proceed against the collateral securing that indebtedness.

##### Table of Contents

The terms of Nalco Companys senior credit agreement limit Nalco Holdings LLC and its
subsidiaries from paying dividends or otherwise transferring their assets to us.

Our operations are conducted through our subsidiaries
and our ability to make payments on any obligations we may have is dependent on the earnings and the distribution of funds from our subsidiaries. However, the terms of Nalco Companys senior credit agreement limit the amount of dividends and
other transfers by Nalco Holdings LLC and its subsidiaries to us.

We could suffer material claims arising from the supply of products
and services.

We assume contractual and tort risks as a natural result of providing sophisticated services and products to our
customers. Broadly speaking, this includes risk of product liability claims (negligence and strict liability), contract claims, professional liability claims or other tort claims, including Legionella exposure. The types of damage that might
be claimed include property damage, personal injury or economic losses. Although we take reasonable steps to limit exposure to these types of claims and mitigate losses should a claim occur, the nature of our business raises the potential of this
risk.

The effects of the recent global economic crisis may impact our business, operating results or financial condition.

The recent global economic crisis has caused a general tightening in the credit markets, lower levels of liquidity, increases in the rates of
default and bankruptcy, and extreme volatility in credit, equity and fixed income markets. These macroeconomic developments could negatively affect our business, operating results or financial condition in a number of ways, including impairments of
goodwill and other intangible and tangible assets. When general economic conditions deteriorate, we may suffer reductions in our sales and profitability. In addition, the financial stability of our customers and suppliers may be compromised, which
could result in additional bad debts for us or non-performance by suppliers. We may also find it more costly or difficult to obtain financing to fund operations or investment opportunities, or to refinance our debt in the future.

Our significant non-U.S. operations expose us to global economic and political changes that could impact our profitability.

We have significant operations outside the United States, including joint ventures and other alliances. We conduct business in approximately 150 countries
and, in 2009, approximately 55% of our net sales originated outside the United States and some of our business is conducted in politically unstable countries. There are inherent risks in our international operations, including:



| |  |  | exchange controls and currency restrictions;
| | - |  | --------------------------------------------



| |  |  | currency fluctuations and devaluations;
| | - |  | ---------------------------------------



| |  |  | tariffs and trade barriers;
| | - |  | ---------------------------



| |  |  | export duties and quotas;
| | - |  | -------------------------



| |  |  | changes in local economic conditions;
| | - |  | -------------------------------------



| |  |  | changes in laws and regulations;
| | - |  | --------------------------------



| |  |  | difficulties in managing international operations and the burden of complying with foreign laws;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | exposure to possible expropriation or other government actions;
| | - |  | ---------------------------------------------------------------



| |  |  | restrictions on our ability to repatriate dividends from our subsidiaries;
| | - |  | --------------------------------------------------------------------------



| |  |  | unsettled political conditions and possible terrorist attacks against American interests; and
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | countries whose governments have been hostile to U.S.-based businesses.
| | - |  | -----------------------------------------------------------------------

Our international operations also expose us to different local political and business risks and challenges. For example, in certain countries we are faced
with periodic political issues that could result in currency

risks or the risk that we are required to include local ownership or management in our businesses. Also, because of uncertainties regarding the interpretation and application of laws and
regulations and the enforceability of intellectual property and contract rights, we face risks in some countries that our intellectual property rights and contract rights would not be enforced by local governments. We are also periodically faced
with the risk of economic uncertainty, which has impacted our business in these countries. Other risks in international business also include difficulties in staffing and managing local operations, including our obligations to design local solutions
to manage credit risk to local customers and distributors.

Our overall success as a global business depends, in part, upon our ability to
succeed in differing economic, social and political conditions. We may not continue to succeed in developing and implementing policies and strategies that are effective in each location where we do business, which could negatively affect our
profitability.

Environmental, safety and production and product regulations or concerns could subject us to liability for fines or
damages, require us to modify our operations and increase our manufacturing and delivery costs.

We are subject to the requirements of
environmental and occupational safety and health laws and regulations in the United States and other countries. These include obligations to investigate and clean up environmental contamination on or from properties or at off-site locations where we
are identified as a responsible party. For example, we are currently identified as a potentially responsible party at certain waste management sites.

We have also been named as a defendant in multi-party and individual lawsuits based on claims of exposure to hazardous materials and claims that our products are defective or dangerous. We have also been named as a defendant in lawsuits
where our products have not caused injuries, but the claimants wish to be monitored for potential future injuries. We cannot predict with certainty the outcome of any such tort claims or the involvement we or our products might have in such matters
in the future and there can be no assurance that the discovery of previously unknown conditions will not require significant expenditures. In each of these chemical exposure cases, our insurance carriers have accepted the claims on our behalf (with
or without reservation) and our financial exposure should be limited to the amount of our deductible; however, we cannot predict the number of claims that we may have to defend in the future and we may not be able to continue to maintain such
insurance.

We have made and will continue to make capital and other expenditures to comply with environmental requirements. Although we
believe we are in material compliance with environmental law requirements, we may not have been and will not at all times be in complete compliance with all of these requirements, and may incur material costs, including fines or damages, or
liabilities in connection with these requirements in excess of amounts we have reserved. In addition, these requirements are complex, change frequently and have tended to become more stringent over time. In the future, we may discover previously
unknown contamination that could subject us to additional expense and liability. In addition, future requirements could be more onerous than current requirements.

The activities at our production facilities are subject to a variety of federal, state, local and foreign laws and regulations (production regulations). Similarly, the solid, air and liquid
waste streams produced from our production facilities are subject to a variety of regulations (waste regulations) and many of our products and the handling of our products are governmentally regulated or registered (product
regulations). Each of the production, waste and product regulations is subject to expansion or enhancement. Any new or tightened regulations could lead to increases in the direct and indirect costs we incur in manufacturing and delivering
products to our customers. For example, the European Commission has imposed new chemical registration requirements on the manufacturers and users of all chemicals, not just those which are considered to be harmful or hazardous. Such regulations,
referred to as REACH, will cause all chemical companies to incur additional costs to conduct their businesses in

European Commission countries. Similarly, the need for certain of our products and services is dependent upon  or triggered by  governmental regulation, and changes in such regulation
could impact our sales of these products or services. In addition to an increase in costs in manufacturing and delivering products, a change in production regulations or product regulations could result in interruptions to our business and
potentially cause economic or consequential losses should we be unable to meet the demands of our customers for products.

We may not be
able to achieve all of our expected cost savings.

For the years 2004 through 2008, our average annual cost savings were $84 million,
during which our historic annual target was $75 million. In 2009, we achieved cost savings of $122 million, which was well above our increased annual goal of $100 million. A variety of risks could cause us not to achieve the benefits of our expected
cost savings, including, among others, the following:



| |  |  | higher than expected severance costs related to staff reductions;
| | - |  | -----------------------------------------------------------------



| |  |  | higher than expected retention costs for employees that will be retained;
| | - |  | -------------------------------------------------------------------------



| |  |  | delays in the anticipated timing of activities related to our cost-saving plan, including the reduction of inefficiencies in our administrative and
overhead functions; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | other unexpected costs associated with operating the business.
| | - |  | --------------------------------------------------------------

We have experienced in the past, and could again experience in the future, difficulties in securing the supply of certain raw materials we and our competitors need to manufacture some of our
products, and we have also been impacted by significant increases in raw material costs.

In 2004 and 2005, certain of the raw
materials used by us and other chemical companies faced supply limitation. If these limitations occur again in the future, we risk shortfalls in our sales and the potential of claims from our customers if we are unable to fully meet contractual
requirements.

Also, limitations on raw materials and rising prices for underlying materials have resulted in the past, and could result in
the future, in price increases for raw materials we purchase. In the past, our margins have been impacted by such raw materials price increases, and our margins could be similarly impacted in the future if we are unable to pass any future raw
material price increases through to our customers.

Our pension plans are currently underfunded and we may have to make significant cash
payments to the plans, reducing the cash available for our business.

We sponsor various pension plans worldwide that are underfunded
and require significant cash payments. For example, in 2008 and 2009, we contributed $86.2 million and $72.9 million, respectively, to our pension plans. We expect to contribute approximately $68 million to our pension plans in 2010. If the
performance of the assets in our pension plans does not meet our expectations, or if other actuarial assumptions are modified, our contributions could be even higher than we expect. If our cash flow from operations is insufficient to fund our
worldwide pension liability, we may be forced to reduce or delay capital expenditures, seek additional capital or seek to restructure or refinance our indebtedness.

As of December 31, 2009, our worldwide pension plans were underfunded by $418.7 million (based on the actuarial assumptions used for financial reporting purposes). Our U.S. pension plans are subject
to the Employee Retirement Income Security Act of 1974, or ERISA. Under ERISA, the Pension Benefit Guaranty Corporation, or PBGC, has the authority to terminate an underfunded pension plan under certain circumstances. In the event our U.S. pension
plans are terminated for any reason while the plans are underfunded, we will incur a liability to the PBGC that may be equal to the entire amount of the underfunding.

We have recorded a significant amount of goodwill and other identifiable intangible assets, and we may never realize the full value of our intangible assets.

We have recorded a significant amount of goodwill and other identifiable intangible assets, including customer relationships, trademarks and developed
technologies. Goodwill and other net identifiable

intangible assets were approximately $2.9 billion as of December 31, 2009, or approximately 58% of our total assets. Goodwill, which represents the excess of cost over the fair value of the
net assets of the businesses acquired, was $1.8 billion as of December 31, 2009, or 36% of our total assets. Goodwill and net identifiable intangible assets are recorded at fair value on the date of acquisition and, in accordance with
authoritative guidance issued by the Financial Accounting Standards Board, will be reviewed at least annually for impairment. Impairment may result from, among other things, deterioration in our performance, adverse market conditions, adverse
changes in applicable laws or regulations, including changes that restrict the activities of or affect the products and services sold by our business, and a variety of other factors. We recognized a $544.2 million goodwill impairment charge in 2008,
reducing the goodwill balance of our Paper Services reporting unit to zero. Some of the products and services we sell to our customers are dependent upon laws and regulations, and changes to such laws or regulations could impact the demand for our
products and services. The amount of any quantified impairment must be expensed immediately as a charge to results of operations. Depending on future circumstances, it is possible that we may never realize the full value of our intangible assets.
Any future determination of impairment of a significant portion of goodwill or other identifiable intangible assets would have an adverse effect on our financial condition and results of operations.

Our future success will depend in part on our ability to protect our intellectual property rights, and our inability to enforce these rights could
permit others to offer products competitive with ours, which could reduce our ability to maintain our market position and maintain our margins.

We rely on the patent, trademark, copyright and trade secret laws of the United States and other countries to protect our intellectual property rights. However, we may be unable to prevent third parties from using our intellectual property
without authorization, and we face risks in some countries that our intellectual property rights and contract rights would not be enforced by local governments. The use of our intellectual property by others could reduce any competitive advantage we
have developed or otherwise harm our business. If we had to litigate to protect these rights, any proceedings could be costly, and we may not prevail.

We have obtained and applied for several U.S. and foreign trademark registrations, and will continue to evaluate the registration of additional service marks and trademarks, as appropriate. Our pending applications may not be approved by
the applicable governmental authorities and, even if the applications are approved, third parties may seek to oppose or otherwise challenge these registrations. A failure to obtain trademark registrations in the United States and in other countries
could limit our ability to protect our trademarks and impede our marketing efforts in those jurisdictions.

We may be subject to
information technology system failures, network disruptions and breaches in data security.

We rely to a large extent upon
sophisticated information technology systems and infrastructure. The size and complexity of our computer systems make them potentially vulnerable to breakdown, malicious intrusion and random attack. Likewise, data privacy breaches by employees and
others with permitted access to our systems may pose a risk that sensitive data may be exposed to unauthorized persons or to the public. While we have invested heavily in protection of data and information technology, there can be no assurance that
our efforts will prevent breakdowns or breaches in our systems that could adversely affect our business.

The market price of our common
stock may be volatile, which could cause the value of your investment to decline.

Securities markets worldwide experience significant
price and volume fluctuations. This market volatility, as well as general economic, market or potential conditions, could reduce the market price of our common stock in spite of our operating performance. In addition, our operating results could be
below the expectations of securities analysts and investors, and in response, the market price of our common stock could decrease significantly.

Provisions in our amended and restated certificate of incorporation and bylaws and Delaware law may
discourage a takeover attempt.

Provisions contained in our amended and restated certificate of incorporation and bylaws and Delaware
law could make it more difficult for a third party to acquire us, even if doing so might be beneficial to our stockholders. Provisions of our amended and restated certificate of incorporation and bylaws impose various procedural and other
requirements, which could make it more difficult for stockholders to effect certain corporate actions. For example, our amended and restated certificate of incorporation authorizes our Board of Directors to determine the rights, preferences,
privileges and restrictions of unissued series of preferred stock, without any vote or action by our stockholders. Thus, our Board of Directors can authorize and issue shares of preferred stock with voting or conversion rights that could adversely
affect the voting or other rights of holders of our common stock. These rights may have the effect of delaying or deterring a change of control of our company. In addition, a change of control of our company may be delayed or deterred as a result of
our having three classes of directors. Additionally, Section 203 of the Delaware General Corporation Law provides that, subject to specified exceptions, a Delaware corporation shall not engage in business combinations with any entity that
acquires enough shares of our common stock without the consent of our Board of Directors to be considered an interested stockholder under Delaware law for a three-year period following the time that the stockholder became an interested
stockholder. These provisions could limit the price that certain investors might be willing to pay in the future for shares of our common stock.



|ITEM 1B. | UNRESOLVED STAFF COMMENTS
|-------- | -------------------------

We have
received no written comments regarding our periodic or current reports from the staff of the Securities and Exchange Commission that were issued 180 days or more preceding the end of our 2009 fiscal year and that remain unresolved.



|ITEM 2. | PROPERTIES
|------- | ----------

Our principal administrative
offices and research center are located in Naperville, Illinois. These facilities are leased. We maintain administrative and research facilities in Sugar Land, Texas and Leiden, Netherlands, both of which we own, and in Singapore and Shanghai,
China, both of which we lease. We position our manufacturing locations and warehouses in a manner to permit ready access to our customers. We operate 16 plants in North America, 6 plants in Latin America, 10 plants in Europe and the Middle East and
13 plants in the Asia/Pacific region. We own all of our major manufacturing facilities and we also have a network of small leased sales offices in the United States and, to a lesser extent, in other parts of the world.



|ITEM 3. | LEGAL PROCEEDINGS
|------- | -----------------

Various claims,
lawsuits and administrative proceedings are pending or threatened against us and our subsidiaries, arising from the ordinary course of business with respect to commercial, contract, intellectual property, product liability, employee, environmental
and other matters. Historically, we have not faced any litigation matters or series of litigation matters that have had a material adverse impact on our business. In addition, we do not believe that there is any pending or reasonably predictable
litigation, either individually or in the aggregate, that is likely to have a material adverse effect on our financial condition, results of operations, liquidity or cash flow. However, we cannot predict with certainty the outcome of any litigation
or the potential for future litigation.

Our common stock is traded on the New York Stock Exchange (ticker symbol NLC). As of February 8, 2010, the number of holders of record of our common
stock was approximately 48,100.

High and low sales prices per share of our common stock for each quarter during 2009 and 2008 were as
follows:

The closing sales price on
December 31, 2009 was $25.51.

Our Board of Directors instituted a quarterly cash dividend by declaring a dividend of $0.035 per share of
common stock in the quarter ended March 31, 2007 and in each succeeding quarter. Nalco Holding Company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. However, the terms of Nalco Companys senior credit agreement limit the amount of dividends and other transfers by Nalco Holdings LLC and its subsidiaries to Nalco Holding Company.
As a result, Nalco Holding Company is limited in its ability to pay dividends on its common stock.

On July 31, 2007, our Board of
Directors authorized a $300 million share repurchase program, and gave our management discretion in determining the conditions under which shares may be purchased from time to time. We intend to repurchase all shares under this authorization in open
market transactions. There is no set timetable for share repurchases, and the program has no stated expiration date. There were no repurchases of any of the Companys common stock by or on behalf of the Company during the fourth quarter 2009.

|(4) | Net earnings (loss) per share attributable to Nalco Holding Company common shareholders is calculated by dividing net earnings (loss) attributable to Nalco Holding
Company by the weighted average shares outstanding.

|(5) | EBITDA, a measure used by management to measure operating performance, is defined as net earnings plus interest, taxes, depreciation and amortization. EBITDA is
reconciled to net earnings (loss) in the following table. We believe EBITDA is useful to the investors because it is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in our industry.
EBITDA is not a recognized term under U.S. GAAP and does not purport to be an alternative to net earnings (loss) attributable to Nalco Holding Company as an indicator of operating performance or to cash flows from operating activities as a measure
of liquidity. Because not all companies use identical calculations, this presentation of EBITDA may not be comparable to other similarly titled measures of other companies. Additionally, EBITDA is not intended to be a measure of cash flow for
managements discretionary use, as it does not consider certain cash requirements such as interest payments, tax payments and debt service requirements. The amounts shown for EBITDA as presented herein differ from the amounts calculated under
the definition of EBITDA used in our debt instruments. The definition of EBITDA used in our debt instruments is further adjusted for certain cash and non-cash charges and is used to determine compliance with financial covenants and our ability to
engage in certain activities such as incurring additional debt and making certain payments.

There may be other factors that may cause our actual results to differ materially from the forward-looking
statements.

All forward-looking statements attributable to us or persons acting on our behalf apply only as of the date of this Annual Report

Use of Non-GAAP Financial Measures

Direct contribution, EBITDA, Adjusted EBITDA, Adjusted Effective Tax Rate, Adjusted Earnings Per Share and Free Cash Flow are measures used by management to
evaluate operating performance.

Direct contribution is defined as net sales, less cost of product sold, selling and service expenses,
marketing expenses, and research expenses. EBITDA is defined as net earnings attributable to Nalco Holding Company plus interest, taxes, depreciation and amortization. Adjusted EBITDA is defined as EBITDA further adjusted for restructuring expenses
and certain unusual items. Adjusted Effective Tax Rate is defined as the income tax provision, excluding the tax expense (benefit) of specified transactions, divided by earnings (loss) before income taxes, excluding the earnings (loss) before income
taxes attributable to those specified transactions. Adjusted Earnings Per Share is defined as diluted net earnings per share attributable to Nalco Holding Company common shareholders, adjusted for the per-share impact of restructuring expenses,
which fluctuate significantly from year to year, and other specified transactions that are unusual in nature. Free Cash Flow is defined as net cash provided by operating activities, less capital expenditures and net earnings attributable to
noncontrolling interests.

Direct contribution provides investors with the measurement used by our management to evaluate the performance of
our segments. We believe EBITDA is useful to the investors because it is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in our industry. We believe Adjusted EBITDA, Adjusted Effective
Tax Rate and Adjusted Earnings Per Share are useful for investors to fully understand our operating performance. We believe Free Cash Flow provides investors with a measure of our ability to generate cash for the optimization of our capital
structure.

Direct contribution, EBITDA, Adjusted EBITDA and Free Cash Flow are not recognized terms under U.S. GAAP and do not purport to be
alternatives to net earnings as an indicator of operating performance or to cash flows from operating activities as a measure of liquidity. Adjusted Effective Tax Rate and Adjusted Earnings Per Share also are not recognized terms under U.S. GAAP.
Adjusted Effective Tax Rate does not purport to be an alternative to the actual effective tax rate as a measure of the relationship between the income tax provision and earnings (loss) before income taxes, and Adjusted Earnings Per Share does not
purport to be an alternative to diluted earnings per share as a measure of operating performance. Direct contribution is reconciled to consolidated earnings before income taxes in Note 22 of our consolidated financial statements included in
Item 8 of this Annual Report. The most direct comparable GAAP financial measures of each other non-GAAP financial measure, as well as the reconciliation between each other non-GAAP financial measure and the GAAP financial measure, are presented
in the discussions of the non-GAAP financial measures below. Because not all companies use identical calculations, our measures may not be comparable to other similarly titled measures of other companies.

Critical Accounting Policies and Estimates

Revenue Recognition

Revenue from sales of products, including chemicals and equipment, is recognized at the time:
(1) persuasive evidence of an arrangement exists, (2) ownership and all risks of loss have been



31



---

##### Table of Contents

transferred to the buyer, which is generally upon shipment, (3) the price is fixed and determinable, and (4) collectibility is reasonably assured. Revenue from services is recognized
when the services are provided to the customer.

Significant estimates used in recognizing revenues include (1) the delay between the
time that chemicals/equipment are shipped and when they are received by customers and title transfers and (2) the amount of credit memos to be issued in subsequent periods.

We provide our chemical and equipment offerings to our customers using various commercial arrangements, but the following are most commonly used:

Ship-and-bill arrangements.    Following the receipt of a purchase order from the customer, we invoice the customer at the time
that the chemicals/equipment are shipped, based on agreed pricing and the volume of chemicals shipped or units of equipment shipped. At the end of each period, for those shipments where title to the product and the risks of loss and rewards of
ownership do not transfer until the product has been received by the customer, adjustments to revenues and cost of product sold are made to account for the delay between the time that the chemicals/equipment are shipped and when they are received by
the customer. Our sales policy does not provide for general rights of return and does not contain customer acceptance clauses.

Usage with
level billing arrangements.At the beginning of the contractual relationship, we prepare an estimate of the chemicals that will be used by the customer. As agreed with the customer, a fixed amount is invoiced monthly based
on this estimate. At the end of each quarter, we reconcile the actual amount of chemicals used by the customer and bill the customer for products actually used during that period. Revenue is recognized to reflect actual usage. For any products not
consumed in the customers operations in a particular period, we retain ownership of such products on a consigned basis and do not recognize any revenue.

Fixed-fee arrangements.    At the beginning of the contractual relationship, we prepare an estimate of the chemicals that will be used by the customer during the contractual
period, which is usually twelve months. A fixed amount is automatically invoiced to the customer on a periodic basis, typically monthly. We retain ownership, on a consigned basis, of any inventory at the customer site that is not consumed in the
customers operations in a particular period. Revenue is recognized on a ratable basis over the contractual period, which is generally consistent with the customers usage of the chemicals.

Under these arrangements, as part of the sales cycle for our chemical programs, our technical and sales representatives may visit our customers
facilities to develop and monitor the chemical programs. Typically, there is no contractual obligation for these visits, or any penalty for not visiting the customer sites. During these visits, our employees perform routine testing activities to
ensure that our chemical products functionalities are having the desired effect on the customers equipment (e.g., boilers, chillers and water treatment plants). In the majority of instances, our customers perform the on-going application
of the chemicals. At the same time, the sales representatives investigate and determine whether the customers have needs for additional applications from Nalco. We consider our technical and sales representatives activities in this regard to
be an integral and inherent part of our selling process and not a separate deliverable for revenue recognition purposes.

Some of our
customers, however, look to us for our technical expertise only, without the purchase of chemicals/equipment. We offer specialized services designed to assess, control, and reduce risk from water-borne pathogens such as Legionella, and we
provide other technical and analytical services.

We invoice for our services using various commercial arrangements, but the following
arrangements are the most common:

Perform-and-bill arrangements.    Revenue is recognized in the same period that
the related service is performed, based on the agreed pricing, which can be either a price per hour or a fixed fee.



32

##### Table of Contents

Fixed-fee arrangements.At the beginning of the contractual relationship, we
estimate the saleable service that will be performed during a given period, usually twelve months. A fixed amount is automatically invoiced to the customer on a periodic basis, which may be monthly, quarterly, or annually, either in arrears or in
advance of the services provided. Because an unspecified number of similar acts are performed within a fixed period of performance, revenue is recognized ratably over the period of performance.

Time and material arrangements.The fee with the customer is structured on a time and material basis, and revenue is
recognized in the same period that the work is completed.

In certain arrangements, which are usually reserved for our largest customers, we
provide some combination or all of the following deliverables: (1) chemicals, (2) equipment and (3) on-site technical expertise. In these arrangements, we usually remain the owner of any equipment at the customer site. At the end of
the contractual relationship, the equipment is either recovered or sold to the customer or a competitor. Additionally, our representatives may have a regular presence at a customers facility, which is provided under a contract. Over time, the
representatives have gained a true expertise in the particular production/water treatment process at the customers facility, and are able to selectively apply our specific chemical programs given the customer environment (water quality,
equipment type, etc.). The regular presence of the representative permits us to closely track the results of the program and to make modifications to the program as necessary for the highest efficiency.

The following two types of commercial arrangements are the most commonly used for the sale of multiple deliverables:

Production-based arrangements.    Our billing is based on a customers production-based formula (e.g., dollars per ton of
paper produced) within certain technical parameters. We use a combination of our service chemicals, on-site technical expertise and equipment to satisfy the customer requirement. The chemicals and equipment used and on-site technical expertise
required are highly correlated with the customers production. Revenue is recognized monthly based on the production-based formula.

Usage-based arrangements.    For these arrangements, we invoice according to the consumption of chemicals by the customer. The agreed price by kilogram or pound of chemical consumed also includes the availability
of on-site expertise and the use of equipment to satisfy the customer requirement. Revenue is recognized monthly based on the usage-based formula.

For all of our commercial arrangements, we also record estimated reserves for anticipated non-collectible accounts and for product returns and other credits at the time revenue is recognized.

Impairment of Long-Lived Assets Other Than Intangibles

Property, plant, and equipment held for use is grouped for impairment testing at the lowest level for which there is identifiable cash flows. Impairment testing of an asset group occurs whenever events or
changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Such circumstances may include, for example, a significant decrease in the market price of a long-lived asset grouping, a significant adverse change in
the manner in which the asset grouping is being used or in its physical condition, a history of operating or cash flow losses associated with the use of the asset grouping, or changes in the expected useful life of the long-lived assets.

If such circumstances are determined to exist, an estimate of undiscounted future cash flows produced by that asset group is compared to the carrying
value to determine whether impairment exists. If an asset group is determined to be impaired, the loss is measured based on the difference between the asset groups fair value and its carrying value. The asset groups fair value is based
on quoted market prices in active markets, if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including a discounted value of estimated future cash flows. Assets to be
disposed of by sale are reported at the lower of carrying amount or fair value less cost to sell.

##### Table of Contents

The assumptions underlying cash flow projections represent managements best estimate at the time of
the impairment review. Factors that management must estimate include industry and market conditions, sales volume and prices, costs to produce, inflation, etc. Changes in key assumptions or actual conditions that differ from estimates could result
in an impairment charge. We use reasonable and supportable assumptions when performing impairment reviews and cannot predict the occurrence of future events and circumstances that could result in impairment charges.

As of December 31, 2009, we had not identified any significant asset groups that had expected undiscounted future cash flows that were not
substantially in excess of the carrying values, other than certain long-lived assets held and used that were written down to their estimated fair value during 2009, which resulted in an impairment loss of $20.2 million.

PORTA-FEED stainless steel containers, utilized to ship chemicals, represent approximately 6.9% of our property, plant and equipment and are managed
globally to optimize the delivery of chemicals to customer and company sites around the world. Due to their high mobility, there is a risk that PORTA-FEED units could be damaged or lost in transit. We perform continuous cycle counts of our
PORTA-FEED units and when such counts are inconsistent with our tracking system, we investigate the discrepancy in order to locate the container. If the PORTA-FEED unit is not found, we write off the asset immediately.

We capitalize qualifying costs incurred in the acquisition and development of software for internal use, including the costs of the software, materials,
consultants, interest and payroll and payroll-related costs for employees dedicated to the development. We must use our judgment in determining whether the direct costs of materials and services consumed in developing or obtaining internal-use
computer software and an employees time and travel expenses directly associated with developing software are recoverable and should be capitalized. We base our determination on the nature and the extent of the activity that the employee is
performing.

Goodwill and Other Intangible Assets

The carrying values of goodwill and other intangible assets with indefinite lives are reviewed for possible impairment annually on the first day of our fourth quarter, October 1, or when events or
changes in business circumstances indicate that the carrying value may not be recoverable. The carrying values of intangible assets with finite lives are reviewed for possible impairment when events or changes in business circumstances indicate that
the carrying value may not be recoverable.

We have defined our reportable segments as our reporting units for our goodwill impairment
testing. We use a two-step process to test goodwill for impairment. First, the reporting units fair value is compared to its carrying value. Fair value is estimated using the market approach, as well as the income approach, based on discounted
cash flow projections. If a reporting units carrying amount exceeds its fair value, an indication exists that the reporting units goodwill may be impaired, and the second step of the impairment test would be performed. The second step of
the goodwill impairment test is used to measure the amount of the impairment loss, if any. In the second step, the implied fair value of the reporting units goodwill is determined by allocating the reporting units fair value to all of
its identifiable assets and liabilities other than goodwill in a manner similar to a purchase price allocation. The implied fair value of the goodwill that results from the application of this second step is then compared to the carrying amount of
the goodwill and an impairment charge would be recorded for the difference if the carrying value exceeds the implied fair value of the goodwill.

We test the carrying value of other intangible assets with indefinite lives by comparing the fair value of the intangible assets to the carrying value. Fair value is estimated using a relief of royalty approach, a discounted cash flow
methodology, using market-based royalty rates.

The estimates and assumptions we use are consistent with the business plans and estimates we
use to manage operations and to make acquisition and divestiture decisions. The use of different assumptions

##### Table of Contents

could impact whether an impairment charge is required and, if so, the amount of such impairment. Future outcomes may also differ. If we fail to achieve estimated volume and pricing targets,
experience unfavorable market conditions or achieve results that differ from our estimates, then revenue and cost forecasts may not be achieved, and we may be required to recognize impairment charges.

We performed our annual impairment test as of October 1, 2009. Because the goodwill of our Paper Services reporting unit was written down to zero in 2008,
it was not necessary to include it in our annual impairment test for 2009. However, we did estimate its fair value in order to compare the aggregate fair value of all of our reporting units to our market capitalization as of October 1, 2009. The
fair value of our reporting units was estimated based on a discounted projection of cash flows. The rates used in determining discounted cash flows for each of our reporting units was a rate corresponding to our cost of capital, adjusted for risk
where appropriate. In determining estimated future cash flows, current and future levels of income were considered that reflected business trends and market conditions.

The aggregate fair value of our reporting units as determined in the first step of our annual impairment test was reconciled to our market capitalization as of October 1, 2009. The aggregate fair value of
our reporting units was 44% higher than our market capitalization, which represented an implied control premium. We believe this implied control premium is reasonable in light of market and economic conditions.

Critical assumptions used in estimating the fair value of our Water Services and Energy Services reporting units for the impairment test included the
discount rate and the terminal growth rate for each unit. The following table summarizes those assumptions:



|                |  |               |   |  |                     |  
|--------------- |  | ------------- | - |  | ------------------- | -
|                |  | Discount Rate |   |  | TerminalGrowth Rate |  
|Water Services  |  | 10.0          | % |  | 3.0                 | %
|Energy Services |  | 10.0          | % |  | 3.0                 | %

The results of the first step
of our 2009 annual impairment test indicated that the fair values of our reporting units exceeded their carrying values. The following table presents the amount of headroom (the percentage difference between each reporting units fair value and
carrying value) of our Water Services and Energy Services reporting units as of the date of our annual impairment test, October 1, 2009:



|                |  |              |  
|--------------- |  | ------------ | -
|                |  | Headroom (1) |  
|Water Services  |  | 84           | %
|Energy Services |  | 169          | %





|(1) | Headroom = (fair value  carrying value) / carrying value, expressed as a percentage.

test:

Pensions

Accounting for pensions involves the selection of a discount rate and an expected rate of return that we apply to a market-related value of plan assets. This methodology generally reduces the volatility
of pension expense that would have otherwise resulted from changes in the value of the pension plan assets and pension liability discount rates. The discount rate used to determine the present value of our future U.S. pension obligations is based on
a yield curve constructed from a portfolio of high quality corporate debt securities with various maturities. Each years expected future benefit payments are discounted to their present value at the appropriate yield curve rate, thereby
generating the overall discount rate for U.S. pension obligations. The discount rates for our foreign pension plans are selected by reference to high quality corporate bond rates in those countries that have developed corporate bond markets. In
those countries where developed corporate bond markets do not exist, the discount rates are selected by reference to local government bond rates with a premium added to reflect the additional risk for corporate bonds.

The assets in the principal domestic pension plan are diversified across equity and fixed income investments. The investment portfolio has target
allocations of approximately 49% equity, 32% fixed income and 19% alternative investments such as hedge funds and private equity. Other assets such as real estate may be used judiciously to enhance portfolio returns and diversification.

The expected long-term rate of return on plan assets is established using historical market data for each asset class as well as the
target allocation. Historical markets are analyzed and long-term historical relationships between equity and fixed income investments are preserved consistent with the widely accepted capital market principle that assets with higher
volatility will generate a greater return over the long run. Active management is employed in most asset classes, which also contributes to the return assumption. The total weighted-average return on each asset class supports our long-term
expected rate of return assumption.

We review our long-term rate of return assumptions annually. While we believe our assumptions of future
returns are reasonable and appropriate, significant differences in our actual experience or significant changes in our assumptions may materially affect our pension obligations and our future pension expense. The expected long-term rate of return is
applied to a calculated value of plan assets, which recognizes changes in the fair value of plan assets in a systematic manner over five years in determining pension expense.

For the year ended December 31, 2009, we recognized consolidated pension expense, including settlements, of approximately $47 million. We expect pension expense, including forecasted settlements, to
decrease to about $21 million in 2010. Holding all other factors constant, an increase/decrease in the discount rate used to measure plan liabilities of one quarter of a percentage-point would decrease/increase 2010 pension expense and the benefit
obligation by approximately $2 million and $40 million, respectively. Also, holding all other factors constant, an increase/decrease in the expected long-term rate of return of one quarter of a percentage-point would decrease/increase 2010 pension
expense by approximately $1 million.

Other Postretirement Benefits

Accounting for other postretirement benefits requires the selection of a discount rate and health care cost trend rates used to value benefit obligations.
The discount rate used to determine the present value of our future postretirement benefit obligations other than pensions is based on a yield curve constructed from a portfolio of high quality corporate debt securities with various maturities. Each
years expected future benefit payments are discounted to their present value at the appropriate yield curve rate, thereby generating the overall discount rate for our other postretirement benefit obligations. We develop our estimate of the
health care cost trend rates through review of our recent health care cost trend experience and discussions with our actuary regarding the experience of similar companies.

For the year ended December 31, 2009, we recognized consolidated other postretirement benefit expense of approximately $6 million, and we expect it to be approximately $11 million in 2010. Holding

all other factors constant, an increase/decrease in the discount rate used to measure plan liabilities of one quarter of a percentage-point would decrease/increase 2010 other postretirement
benefit expense by less than $1 million. See Note 14 of our consolidated financial statements included in Item 8 of this Annual Report for details of the impact of a one-percentage-point change in assumed health care cost trend rates on other
postretirement benefit expense and the postretirement benefit obligation.

Income Taxes

We estimate our income tax expense in each of the jurisdictions in which we operate in accordance with authoritative guidance issued by the Financial
Accounting Standards Board (FASB). This results in our recording deferred tax assets and liabilities in the consolidated balance sheet to recognize the temporary differences caused by the timing of recognition of income and expense for financial
statement and tax purposes. Valuation allowances are recorded based on the realizability of the deferred tax assets. Relevant factors to determine the realizability of the assets include future taxable income, the expected timing of the reversal of
temporary differences, tax planning strategies and the expiration dates of the various tax attributes. Valuation allowances are established for those assets that are determined to be more likely than not to expire without benefit, or for which
income of the proper character is not anticipated.

The effect of a valuation allowance for a deferred tax asset that is expected to originate
in the current year is included in the annual effective tax rate for the year. The effect of a change in the beginning-of-the-year balance of a valuation allowance resulting from a change in judgment about the realizability of the related deferred
tax asset in future years is recognized in the interim period in which the change occurs.

The tax positions we take are based on our
interpretations of tax laws and regulations in the applicable federal, state and international jurisdictions. We believe that our tax returns properly reflect the tax consequences of our operations, and that our reserves for tax contingencies are
appropriate and sufficient for the positions taken. However, these positions are subject to audit and review by the tax authorities, which may result in future taxes, interest and penalties. Because of the uncertainty of the final outcome of these
examinations, we have reserved for potential reductions of tax benefits (including related interest and penalties) for amounts that do not meet the more-likely-than-not thresholds for recognition and measurement as required by authoritative guidance
issued by the FASB. The tax reserves are reevaluated throughout the year, taking into account new legislation, regulations, case law and audit results.

Environmental

Our business and operations are subject to extensive environmental
laws and regulations governing, among other things, air emissions, wastewater discharges, the use and handling of hazardous substances, waste disposal and the investigation and remediation of soil and groundwater contamination. As with other
companies engaged in similar manufacturing activities and providing similar services, some risk of environmental liability is inherent in our operations.

We have been named as a potentially responsible party, or PRP, by the Environmental Protection Agency or state enforcement agencies at seven waste sites where some financial contribution is or may be
required. These agencies have also identified many other parties who may be responsible for clean up costs at the waste disposal sites. Our financial contribution to remediate these sites is expected to be minor. There has been no significant
financial impact on us up to the present, nor is it anticipated that there will be in the future, as a result of these matters. We have made and will continue to make provisions for these costs if our liability becomes probable and when costs can be
reasonably estimated.

We have also been named as a defendant in a number of lawsuits alleging personal injury due to exposure to hazardous
substances, including multi-party lawsuits alleging personal injury in connection with our products and services. While we do not believe that based upon present information that any of these suits will be material to us, there can be no assurance
that these environmental matters could not have, either individually or in the aggregate, a material adverse effect on our future financial condition or results of operations.

##### Table of Contents

Historically, our expenditures relating to environmental compliance and clean up activities have not been
significant. The environmental reserves represent our current estimate of our proportional clean up costs and are based upon negotiation and agreement with enforcement agencies, our previous experience with respect to clean up activities, detailed
review of known conditions, and information about other PRPs. The reserves are not reduced by any possible recoveries from insurance companies or other PRPs not specifically identified. Although given the evolving nature of environmental
regulations, we cannot determine whether or not a material effect on future operations is reasonably likely to occur, we believe that the recorded reserve levels are appropriate estimates of the potential liability. Although settlements will require
future cash outlays, it is not expected that such outlays will materially impact our liquidity position, although there can be no assurance that such impacts could not occur.

Executive Level Overview

Nalco delivered strong performance in 2009 against the top
priorities we established at the beginning of the year, particularly given the very difficult business economy.



| |  |  | We made continued improvement in safety, maintaining top quartile status in our Total Recordable Incident Rate.
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | We significantly exceeded our goal of $100 million in cost savings and efficiency improvements, by delivering $122 million of ongoing productivity
gains and an additional $38 million of one-time savings. Nearly two-thirds of these savings were realized in cost of product sold, which contributed to the gross profit margin for 2009 increasing to 45.6% from the 43.5% for 2008.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We focused on profitable growth opportunities by shifting our employee base to markets such as China and India, and by strengthening our executive
leadership capability in growth markets. We continued to expand the capabilities of our key technologies, such as 3D TRASAR, and we began to implement a Commercial Excellence project that is aimed at gaining market share by improving sales alignment
with customer needs.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We substantially increased our cash flow by strengthening operating discipline, as we significantly reduced our days of inventory and receivables and
extended payables.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We strengthened our future by expanding our research and development centers, commercializing new technologies, developing a comprehensive industrial
water treatment strategy to broaden and differentiate our offerings in the industrial water market, and developing our brand as a sustainable solutions provider through extensive media coverage.

Net sales for the year ended December 31, 2009 declined 11.1% to $3,746.8 million from $4,212.4 million in 2008 due to weakness in paper markets,
depressed natural gas drilling activity, and extended shutdowns and permanent closures amongst customers in the mining, manufacturing and primary metals markets. Organic sales, defined as nominal, or actual, sales less the impacts of changes in
foreign currency translation rates and acquisitions and divestitures, decreased 6.9%.

Diluted earnings per share was 44 cents in 2009,
compared to a goodwill-impairment-driven diluted loss per share of $2.44 in 2008. Adjusted Earnings Per Share, which excludes the after-tax impacts of restructuring expenses and other specified transactions that are unusual in nature, was 92 cents
in 2009, compared to $1.24 in 2008. Adjusted Earnings Per Share is reconciled to the diluted earnings (loss) per share as follows:

EBITDA was $569.1 million and $155.8 million
for the years 2009 and 2008, respectively. Adjusted EBITDA, which adjusts EBITDA for restructuring expenses and certain other unusual items, decreased 5.2% to $658.8 million in 2009 from the $695.3 million for 2008. The decrease was mostly due to
unfavorable changes in foreign currency translation rates. Net earnings (loss) attributable to Nalco Holding Company is reconciled to EBITDA and Adjusted EBITDA as follows:

Among the items that contributed to such strong results in 2009 were focused efforts and resulting improvements in our
management of working capital, as evidenced by:



| |  |  | A reduction in accounts receivable days sales outstanding to 64 days from 71 days.
| | - |  | ----------------------------------------------------------------------------------



| |  |  | A reduction in days investment in inventory to 55 days from 70 days.
| | - |  | --------------------------------------------------------------------



| |  |  | An increase in accounts payable days outstanding to 54 days from 47 days.
| | - |  | -------------------------------------------------------------------------

The significant Free Cash flow generated during 2009 was mostly used to pay down more than $300 million of debt, and our performance was instrumental in our
ability to undertake refinancings that moved a significant portion of nearer-term maturities to 2016 and beyond.

Other significant items
included in our 2009 financial results are the following:



| |  |  | We incurred $47.8 million in restructuring expenses compared to $33.4 million in 2008, as we continuously redesign and optimize business and work
processes. The 2009 amount includes $20.2 million of non-cash asset impairment charges associated with plant closings, as we move to a more optimal manufacturing footprint.

2010 Outlook

We are stepping up our growth efforts as we see the beginning of an economic recovery that should create increased demand for our expertise in creating an efficient, recyclable and reliable source of clean industrial water. Also, as energy
costs continue to rise, our energy production and efficiency expertise has increased value to energy customers pursuing natural resources and industrial customers concerned with efficient use of energy and cost control. Against this backdrop of
growing demand and our proven ability to strengthen our capabilities, even in a tumultuous business environment such as 2009, our priorities in 2010 will start, as always, with safety, and will continue the focus on activities that improve our top
and bottom line results.



| |  |  | First, continue to improve our safety performance.
| | - |  | --------------------------------------------------



| |  |  | Second, generate focused, profitable growth by pursuing high-growth geographies and industry segments, maintaining technological leadership, building
upon our existing customer base, and benefiting from our global resource advantage.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Third, increase the amount of time that our sales teams spend in front of customers identifying new performance improvement opportunities, creating
solutions and selling new business, while reducing time spent on administrative tasks and low-value activities.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Fourth, continue to achieve improvements in productivity, with a goal of at least $100 million in cost savings and efficiency gains.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Fifth, generate Free Cash Flow of more than $100 million, recognizing that returning to growth will require more working capital dollars and capital
investment.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Sixth, continue to strengthen our future, by training and developing our employees, strengthening our technology leadership through continued
market-focused innovation, building the Nalco brand, and increasing customer loyalty through a broader and more thorough implementation of our Six Service Standards approach to customer service management.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We are optimistic about the success we can achieve in 2010 in a slowly recovering economy, because of our demonstrated capabilities in creating value for
our customers and the increased customer emphasis on water, energy and air issues that drive our clean technology business.

Results of
Operations

Year Ended December 31, 2009 Compared to the Year Ended December 31, 2008

Consolidated

Net
sales for the year ended December 31, 2009 were $3,746.8 million, a decrease of 11.1% from the $4,212.4 million reported for the year ended December 31, 2008. On an organic basis, which excludes the impacts of changes in foreign
currency translation rates and acquisitions and divestitures, net sales declined 6.9% as a result of the weak global economic environment. Changes in foreign currency translation rates accounted for a 3.4% drop in our sales, and the 2008 divestiture
of our Finishing Technologies surface treatment business accounted for the majority of the remaining 0.8% sales decline. Nominal, or actual, sales were lower in every region, with Europe, Africa and Middle East down 16.8%, and North America,
Asia/Pacific and Latin America down 11.3%, 4.6%, and 3.6% respectively. On an organic basis, Latin America grew 5.2%, but North America reported an organic decline of 9.6%, Europe, Africa and Middle East was down 9.1%, and Asia/Pacific was lower by
2.2%.

Gross profit, defined as the difference between net sales and cost of product sold, of $1,709.8 million for the year
ended December 31, 2009 dropped $124.3 million, or 6.8%, from the $1,834.1 million for 2008.

##### Table of Contents

On an organic basis, gross profit decreased by 2.4%, driven by the 6.9% organic sales decline; however, the decline was successfully tempered by cost savings and process efficiencies. As a
result, the gross profit margin improved by 2.1 percentage points to 45.6% in 2009 compared to 43.5% in 2008.

Selling, administrative,
and research expenses for the year ended December 31, 2009 of $1,210.2 million decreased $39.8 million, or 3.2%, from the $1,250.0 million for the year ended December 31, 2008. Organically, selling, administrative, and research
expenses increased by $10.4 million, or 0.8%. Lower selling expenses, reflecting cost reductions and efficiencies achieved, were offset by higher administrative costs resulting from a settlement charge of $21.4 million for the principal U.S. pension
plan, consulting costs to assist us with certain elements of our productivity initiatives, higher incentive plan expenses, and software asset write-offs.

Amortization of intangible assets was $47.9 million and $56.8 million for the year ended December 31, 2009 and 2008, respectively. The decrease was attributable to lower amortization of
customer relationships, which are amortized using an accelerated method that declines over time.

Restructuring expenseswere
$47.8 million and $33.4 million for the year ended December 31, 2009 and 2008, respectively. In addition to employee severance and related costs associated with the continuing redesign and optimization of business and work processes, the 2009
amount also includes $20.2 million of asset impairment charges associated with planned plant closings to move to a more optimal manufacturing footprint.

Gain on divestiture of $38.1 million in 2008 resulted from the sale of our Finishing Technologies surface treatment business to Chemetall Corp., a subsidiary of Rockwood Holdings.

Impairment of goodwill of $544.2 million in 2008 represents the write off of all goodwill previously allocated to Paper
Services at the time of the Acquisition in 2003. The impairment resulted from a sharp deterioration in conditions within the paper industry and the general economy in late 2008.

Other income (expense), net was a net expense of $ 17.6 million and $17.4 million for the year ended December 31, 2009 and 2008, respectively. A $12.6 million favorable change in
foreign currency transaction gains and losses and other favorable period-over-period changes were offset by a $20.5 million loss on extinguishment of debt in 2009.

Net interest expense, defined as the combination of interest income and interest expense, of $250.6 million for the year ended December 31, 2009 was comparable to the $250.5 million
reported for the year ended December 31, 2008. The impacts of slightly lower average debt levels compared to the year-ago period and lower interest expense on our euro-denominated debt due to translation rate changes were offset by higher
interest expense on our senior discount notes.

The tax provision for 2009 resulted in a 50.0% effective income tax rate,
significantly higher than the U.S. federal statutory tax rate of 35%. This mostly resulted from an increase in valuation allowances of $29.0 million during 2009, which added 21.4 percentage-points to the effective income tax rate. The valuation
allowances were recorded for deferred tax assets that are not likely to be realized, and were due to losses in specific jurisdictions and reduced ability to utilize certain tax loss carryforwards. Restructuring expenses, primarily in Europe, were a
significant cause of the losses.

Our 2009 effective tax rate was favorably impacted by 4.0 percentage-points because we reduced our deferred
tax liabilities for future U.S. state income taxes, primarily due to favorable law changes in key states related to apportioning of income.

The tax provision for 2008 resulted in tax expense on a pretax loss primarily because of two transactions that resulted in expensing goodwill for book purposes that had very little tax basis. The larger of the two transactions was the
impairment of $544.2 million of goodwill that only had $93.7 million of tax basis. As a result, pretax income was reduced by $544.2 million, while the tax provision was only reduced $35.6 million. The second transaction was the sale of the Finishing
Technologies surface treatment business, which resulted in $28.3 million of goodwill being expensed with only $1.6 million of tax benefit. The overall Finishing Technologies sale resulted in $38.1 million of pretax gain and $23.2 million of tax
expense.

We believe excluding these two items from
the actual effective tax rate provides a better basis for comparison to other periods.

During 2008, our U.S. tax position changed such that
we are now able to credit rather than deduct certain foreign taxes. The ability to credit removes nearly all of the incremental tax cost of repatriating dividends to the U.S. from our foreign subsidiaries. The ability to credit also reduces our
expense related to most withholding taxes incurred by the U.S. parent company. The 2008 tax benefit of being able to credit foreign taxes was to release $35.4 million of valuation allowance related to prior year credits, and to further reduce 2008
expense by $29.4 million related to 2008 withholding taxes and foreign dividends, and other foreign taxes.

We assessed the realizability of
the foreign tax credit carryforwards by considering historical trends and future projections of U.S. taxable income, including temporary differences. Our historical U.S. GAAP income includes significant expenses that are not deductible for U.S. tax
purposes, including the 2008 impairment charge, which accelerates the use of the carryforwards on our tax returns. Utilization of the foreign tax credits is dependent upon future U.S. taxable income with the appropriate attributes. The U.S. income
expectations were evaluated along with the expiration dates of the carryforwards, and we concluded that recognition of the tax benefits was appropriate.

Also during 2008, we provided valuation allowances on deferred tax assets in the U.K., primarily related to tax loss carryforwards and future pension obligations. The tax impact was to increase 2008 tax
expense by $20.4 million.

Both 2009 and 2008 were also impacted by foreign taxes provided at other than the 35% U.S. statutory rate, U.S.
state income taxes, nondeductible expense and other permanent differences. See Note 10 of our consolidated financial statements included in Item 8 of this Annual Report for an analysis of the difference between the U.S. statutory federal tax
rate and the effective income tax rate.

Net earnings attributable to noncontrolling interests declined by $0.6 million to $7.4
million for the year ended December 31, 2009 from $8.0 million in 2008, mainly as the result of a decrease in earnings in our Nalco Mobotec Air Protection Technology business.

##### Table of Contents

Water Services reported sales of $1,662.4 million for the year ended December 31, 2009, a 13.4%
decrease from the year ended December 31, 2008. On an organic basis, sales declined 7.7%, with some of the most significant decreases reported by the mining, manufacturing, and metals business. Geographically, every region reported lower sales,
although Latin America ended the year with a 2.8% organic increase over 2008. The 1.7% decrease in sales from acquisitions/divestitures was attributable to the divestiture of our Finishing Technologies surface treatment business in September 2008,
partly offset by the Crossbow acquisition in March 2009.

Paper Services reported sales of $666.0 million for the year ended December 31,
2009, a 14.4% decrease from the $778.0 million reported for 2008. Organic revenues declined 11.8% due to continued weakness in the market across all regions, except Latin America, where sales grew 4.6%.

Energy Services reported sales of $1,418.4 million for the year ended December 31, 2009, a 6.4% decline from the $1,515.4 million for the
year-ago-period. Organically, sales decreased 3.5%, which was mostly attributable to our Adomite business in North America, due to the slowdown in drilling rig activity during 2009. The decline in Adomite revenues was partly offset by organic growth
in the Upstream Oilfield business, with improvements reported by all regions except North America, which reported slightly lower organic sales from 2008.

Direct contribution of Water
Services was $322.4 million for the year ended December 31, 2009, a decrease of 13.1% from the $370.8 million reported for the year-ago period. Organically, direct contribution deceased 7.1%, as the impact of lower sales volumes more than
offset productivity savings and cost controls. The 1.8% decrease in direct contribution from acquisitions/divestitures was mostly attributable to the September 2008 sale of the Finishing Technologies surface treatment business.

Paper Services reported direct contribution of $117.7 million for the year ended December 31, 2009, a 15.5% improvement over the direct contribution of
$101.9 million reported for the year ended December 31, 2008. Organically, direct contribution grew 19.7%, reflecting the positive results of organizational changes, productivity savings and cost controls, which more than offset the organic
sales decrease. As a result, direct contribution as a percent of sales rose to 17.7% in 2009 from 13.1% in 2008.

Energy Services reported
direct contribution of $314.9 million for the year ended December 31, 2009, comparable to the $315.5 million reported for 2008. On an organic basis, direct contribution rose 3.4%, despite the 3.5% organic sales decline, as a result of cost
controls and productivity savings. Direct contribution as a percent of sales increased to 22.2% in 2009 from 20.8% in 2008.

Year Ended
December 31, 2008 Compared to the Year Ended December 31, 2007

Consolidated

Net sales for the year ended December 31, 2008, exceeding $4.0 billion for the first time, were $4,212.4 million, an increase of 7.7% over
the $3,912.5 million reported for the year ended December 31, 2007. On an organic basis, which excludes the impacts of changes in foreign currency translation rates and acquisitions and divestitures, net sales were up 7.8%. Every geographic
region reported organic growth, including Europe, where previous sales declines reversed, and Asia/Pacific, where the economic downturn was experienced first and more severely than other regions.

Gross profit, defined as the difference between net sales and cost of product sold, of
$1,834.1 million for the year ended December 31, 2008 rose $74.4 million, or 4.2%, over the $1,759.7 million for 2007. On an organic basis, gross profit increased by 3.6%. Contributing to the improvement were the impacts of higher sales volumes
and cost savings, which were partly offset by higher product and freight costs. A $12.3 million business interruption insurance settlement from the 2005 U.S. Gulf hurricanes that we received in 2007 also benefited that year. Gross profit margin for
the year ended December 31, 2008 declined to 43.5% compared to 45.0% for the year ended December 31, 2007, mostly as the result of increases in direct material and freight costs of $170.5 million that were not fully offset by $159.2
million of price increases.

Selling, administrative, and research expenses for the year ended December 31, 2008 of
$1,250.0 million increased $43.9 million, or 3.6%, from $1,206.1 million for the year ended December 31, 2007. Organically, selling, administrative, and research expenses grew by $17.0 million, or 1.4%. The greatest portion of this increase was
attributable to selling expense, as a result of our higher salaries, employee incentives, employee benefits, training, travel, and outside services, as we invested in the hiring and training of our sales force in growth markets. Administrative
expenses actually declined by $26.1 million on an organic basis, partly because 2007 expenses included $12.0 million of compensation cost for a grant of nonvested common stock as part of an agreement with our former Chairman and Chief Executive
Officer, Dr. William H. Joyce, who retired effective December 30, 2007. In addition, outside consulting costs related to our work process redesign and legal entity restructuring initiatives were significantly higher in 2007.

Amortization of intangible assets was $56.8 million and $62.1 million for the year ended December 31, 2008 and 2007,
respectively. The decrease was attributable to lower amortization of customer relationships, which are amortized using an accelerated method that declines over time.

Restructuring expenses, representing mostly employee severance and related costs associated with the continuing redesign and optimization of business and work processes, were $33.4 million
and $15.3 million for the year ended December 31, 2008 and 2007, respectively. The increase was mainly the result of a reduction in force of more than 400 positions begun during the fourth quarter of 2008 as part of an organizational
realignment.

Gain on divestitureof $38.1 million in 2008 resulted from the sale of our Finishing Technologies surface
treatment business to Chemetall Corp., a subsidiary of Rockwood Holdings.

Impairment of goodwillof $544.2 million in 2008
represents the write off of all goodwill previously allocated to Paper Services at the time of the Acquisition in 2003. The impairment resulted from a sharp deterioration in conditions within the paper industry and the general economy in late 2008.

Other income (expense), net was a net expense of $17.4 million and $4.8 million for the year ended December 31, 2008 and
2007, respectively. The $12.6 million increase was mainly attributable to an unfavorable change in foreign currency transaction gains and losses of $9.6 million.

Net interest expense, defined as the combination of interest income and interest expense, of $250.5 million for the year ended December 31, 2008 decreased by $14.4 million from the
$264.9 million reported for the year ended December 31, 2007. Translation rate changes due to the weaker U.S. dollar versus the euro increased interest expense by $3.6 million, and accretion of our senior discount notes was $3.2 million higher
than in 2007. However, lower interest rates on our variable rate debt and slightly lower average debt levels compared to 2007 more than offset these increases.

The tax provision for 2008 resulted in tax expense on a pretax loss primarily because of two transactions that resulted in expensing goodwill for book purposes that had very little tax
basis. The larger of the two transactions was the impairment of $544.2 million of goodwill that only had $93.7 million of tax basis. As a result, pretax income was reduced by $544.2 million, while the tax provision was only reduced $35.6 million.
The second transaction was the sale of the Finishing Technologies surface treatment business, which resulted in $28.3 million of goodwill being expensed with only $1.6 million of tax benefit. The overall Finishing Technologies sale resulted in $38.1
million of pretax gain and $23.2 million of tax expense.

We believe excluding these two items from
the actual effective tax rate provides a better basis for comparison to other periods. The Adjusted Effective Tax Rate of 29.6% compares to the 2007 rate of 33.6%. In 2007, the effective tax varied from the U.S. federal statutory rate of 35%
primarily due to incremental U.S. federal income taxes on dividends received from non-U.S. subsidiaries, foreign taxes provided at other than the 35% U.S. statutory rate, U.S. state income taxes, nondeductible expenses and other permanent
differences between income and expense for financial statement and tax purposes. Except as described below, these differences also apply to 2008.

During 2008, our U.S. tax position changed such that we are now able to credit rather than deduct certain foreign taxes. The ability to credit removes nearly all of the incremental tax cost of repatriating dividends to the U.S. from our
foreign subsidiaries. The ability to credit also reduces our expense related to most withholding taxes incurred by the U.S. parent company. The 2008 tax benefit of being able to credit foreign taxes was to release $35.4 million of valuation
allowance related to prior year credits, and to further reduce 2008 expense by $29.4 million related to 2008 withholding taxes and foreign dividends, and other foreign taxes.

We assessed the realizability of the foreign tax credit carryforwards by considering historical trends and future projections of U.S. taxable income, including temporary differences. Our historical U.S.
GAAP income includes significant expenses that are not deductible for U.S. tax purposes, including the impairment charge in 2008, which accelerates the use of the carryforwards on our tax returns. Utilization of the foreign tax credits is dependent
upon future U.S. taxable income with the appropriate attributes. The U.S. income expectations were evaluated along with the expiration dates of the carryforwards, and we concluded that recognition of the tax benefits was appropriate.

Also during 2008, we provided valuation allowances on deferred tax assets in the U.K., primarily related to tax loss carryforwards and future pension
obligations. The tax impact was to increase 2008 tax expense by $20.4 million.

Net earnings attributable to noncontrolling
interests remained relatively flat, declining by $0.2 million to $8.0 million for the year ended December 31, 2008.

Water Services reported sales
of $1,919.0 million for the year ended December 31, 2008, a 4.0% increase over the year ended December 31, 2007. On an organic basis, sales rose 5.4% and more than offset the loss of $79.5 million in revenues earned in 2007 by our waste
coal agglomeration (synfuel) business that ended with a December 31, 2007 tax code expiration.

Direct contribution of Water
Services was $370.8 million for the year ended December 31, 2008, an increase of 0.6% from the $368.6 million reported for 2007 which included the synfuel business. Organically, direct contribution improved 4.8%, as a result of the 5.4% organic
increase in sales. Gross earnings as a percent of sales were unchanged from 2007 at 47.8% during a year of rapid product and freight cost increases, and total operating expenses were up 4.0% organically.

Paper Services reported direct contribution of $101.9 million for the year ended December 31, 2008, a 19.8% decline from the direct contribution of
$127.1 million reported for the year ended December 31, 2007. Organically, direct contribution was down 21.5%, as improvements in Latin America sales and profitability were more than offset by declines in other regions. Operating expenses were
up down 1.2% organically.

Energy Services reported direct contribution of $315.5 million for the year ended December 31, 2008, an 11.4%
increase over the $283.1 million reported for 2007. On an organic basis, direct contribution rose 10.8%. Higher sales volumes drove this growth, but higher product costs reduced gross earnings to 42.2% of sales from 44.8% in 2007. Investments in
additional manpower contributed to increased compensation costs that drove operating expenses up 8.5% organically, with related increases in travel and outside services.

Liquidity and Capital Resources

Operating
activities.    Historically, our main source of liquidity has been our solid cash flow generated by operating activities. For the year ended December 31, 2009, cash provided by operating activities was $593.8
million, an increase of $310.7 million over 2008. The improvement was mostly the result of lower inventory and accounts receivable levels, which resulted in favorable changes from 2008 of $209.9 million and $151.7 million, respectively.

For the year ended December 31, 2008, cash provided by operating activities was $283.1 million, a decrease of $40.3 million from 2007. The decline
was mostly the result of higher inventory levels, which utilized $92.8 million of cash in 2008. A $37.4 million favorable change from 2007 in cash used for accounts receivable offset part of the higher cash usage for inventories.

Investing activities.Net property additions of $102.2 million accounted for most of the $135.8
million of cash used for investing activities during the year ended December 31, 2009. The remainder was mostly attributable to $27.6 million of cash used for business acquisitions. We acquired the assets and business of Crossbow Water for
$22.1 million in March 2009, and we paid $5.5 million of contingent consideration related to acquisitions made prior to 2009.

##### Table of Contents

Cash used for investing activities was $95.4 million for the year ended December 31, 2008, which was
mostly attributable to net property additions of $133.1 million and business purchases of $21.7 million. Partly offsetting these uses of cash was $74.1 million of net proceeds from the sale of the Finishing Technologies business in September 2008.

Cash used for investing activities was $141.7 million for the year ended December 31, 2007, most of which was attributable to net
property additions of $114.6 million. Of the remainder, $27.9 million relates to net cash used to acquire an 87.5% interest in Nalco Mobotec.

Financing activities.    Net cash used to decrease borrowings of $307.0 million accounted for more than three-fourths of the $398.6 million of net cash used for financing activities for the year
ended December 31, 2009. We repaid $0.7 billion of term loans and nearly $1.0 billion of senior notes that were due to mature in 2010 and 2011, respectively, using cash from operations and the proceeds from new term loan borrowings of $1.0
billion and a new senior notes issue of $0.5 billion. Most of the new term loan borrowings become due in 2016, and the new senior notes mature in 2017. Operating cash was also used to repay $98.0 million of borrowings under an accounts receivable
securitization facility. Other significant financing cash outflows during 2009 included $54.7 million to issue the new debt, a $9.2 million premium to redeem a portion of the 2011 senior notes, and common stock dividends of $19.3 million.

Net cash used for financing activities was $232.9 million for the year ended December 31, 2008. Share repurchases of $103.3 million,
common stock dividends of $19.7 million, a net reduction in long-term debt borrowings of $36.8 million, and a $65.8 million net reduction in short-term debt accounted for most of that amount.

Net cash used for financing activities totaled $105.3 million for the year ended December 31, 2007, which was mostly attributable to share repurchases
of $108.0 million, common stock dividends of $15.1 million, term loan repayments of $48.3 million and a $12.8 million reduction in bank overdrafts. These uses were partially offset by $50.0 million borrowed short-term against our revolving credit
facility and a $34.0 million increase in our securitized accounts receivable facility.

Upon the expiration of our $100 million receivables
facility in June 2007, we entered into a new three-year receivables facility that provides up to $160 million in funding.

On July 31,
2007, our Board of Directors authorized a $300 million share repurchase program, and gave our management discretion in determining the conditions under which shares may be purchased from time to time. The program has no stated expiration date. Under
the program, we repurchased 4.6 million of our common shares at a cost of $108.0 million in 2007 and 4.9 million shares at a cost of $103.3 million in 2008, with the last purchase made on November 11, 2008.

Our liquidity requirements are significant, primarily due to debt service requirements as well as research and development and capital investment. Our
primary source of liquidity will continue to be cash flow generated from operations, but we also have availability under a $250 million revolving credit facility and a $160 million receivables facility that matures in June 2010, in each case subject
to certain conditions. We believe that our financial position and financing structure will provide flexibility in worldwide financing activities and permit us to respond to changing conditions in credit markets.

On May 13, 2009, Nalco Company, an indirect subsidiary of Nalco Holding Company, entered into new senior secured credit facilities (the New
Senior Secured Credit Facilities) consisting of a revolving credit facility expiring in May 2014 (the New Revolving Credit Facility) and a $750.0 million term loan facility expiring in May 2016 (the New Term Loan
B). The New Revolving Credit Facility provides for borrowings of up to $250.0 million and replaced the former $250.0 million revolving credit facility that would have otherwise expired on November 4, 2009. The U.S. dollar equivalent of
$150.0 million under the New Revolving Credit Facility can be used, subject to certain collateral obligations, for borrowings by Nalco Company and certain non-U.S. subsidiaries in euros, pounds sterling and other currencies to be agreed. At
December 31, 2009, no borrowings were outstanding under the New Revolving Credit Facility.

Also on May 13, 2009, Nalco Company issued $500.0 million aggregate principal
amount of 81/4% senior unsecured notes (the
Notes). The Notes were issued at a discount of $10.7 million. The Notes mature on May 15, 2017, with interest payable semi-annually on May 15 and November 15 of each year, commencing on November 15, 2009. The Notes do
not have required principal payments prior to maturity. Each of the direct and indirect subsidiaries of Nalco Holdings LLC and Nalco Company that guarantees its obligations under the New Senior Secured Credit Facilities guarantees the Notes.

The terms of the New Senior Secured Credit Facilities also allowed us to make future additional term loan borrowings of
up to $250.0 million on terms to be agreed with future lenders. On November 25, 2009, we entered into Amendment No. 1 (the Amendment) to the New Senior Secured Credit Facilities, which increased the amount of future additional
term loan borrowings from $250.0 million to $550.0 million. The Amendment required that after giving effect to the incurrence of any such additional term loans and the application of the proceeds of such term loans to redeem our 73/4% senior notes due 2011, no more than $200.0 million of the 73/4% senior notes due 2011 could remain outstanding. The
Amendment also permitted us to use up to $200.0 million of our cash to redeem our 73/4% senior notes due 2011 for a period of 180 days from the date of the Amendment, which was done.

On December 7, 2009, Nalco Company entered into a Joinder Agreement to the New Senior Secured Credit Facilities that provided for an additional $300.0 million term loan credit facility expiring in
May 2016 (the Term Loan C). We borrowed the full amount of Term Loan C on December 7, 2009, at a discount of $27.0 million, or 9.00%, of such new term loan.

Borrowings under the New Revolving Credit Facility, New Term Loan B and Term Loan C bear interest at a floating base rate plus an applicable margin. The applicable margin for borrowings under the New
Revolving Credit Facility ranges from 2.00% to 3.00% with respect to base rate borrowings and 3.00% to 4.00% with respect to LIBOR or Eurocurrency borrowings depending on our leverage ratio as defined by the revolving credit agreement. The initial
margin for the New Revolving Credit Facility is 2.50% with respect to base rate borrowings and 3.50% with respect to LIBOR or Eurocurrency borrowings. The applicable margin for borrowings under New Term Loan B is 2.50% with respect to base rate
borrowings and 3.50% with respect to LIBOR or Eurocurrency borrowings, with a base rate floor of 4.00% and a LIBOR or Eurocurrency floor of 3.00%. The applicable margin for borrowings under Term Loan C is 0.75% with respect to base rate borrowings
and 1.75% with respect to LIBOR or Eurocurrency borrowings.

New Term Loan B and Term Loan C are subject to amortization at 1% of the initial
principal amount per annum, payable quarterly. The remaining principal amount of the term loans is due on May 13, 2016.

The New Senior
Secured Credit Facilities are unconditionally guaranteed by Nalco Company, Nalco Holdings LLC (the direct parent company of Nalco Company), and certain domestic subsidiaries of Nalco Holdings LLC. The repayment of these facilities is secured by
substantially all the assets of Nalco Company and the guarantors, including, but not limited to, a pledge of their capital stock and 65% of the capital stock of each non-U.S. subsidiary owned by the guarantors.

The New Senior Secured Credit Facilities and Notes contain a number of covenants that, among other things, restrict, subject to certain exceptions, our
ability to sell assets; incur additional indebtedness or issue preferred stock; repay other indebtedness; pay dividends and distributions or repurchase certain capital stock; create liens on assets; make investments, loans or advances; make
acquisitions, mergers or consolidations; enter into sale and leaseback transactions; engage in certain transactions with affiliates; amend certain material agreements governing our indebtedness; change our business; and enter into hedging
agreements. In addition, the New Senior Secured Credit Facilities and Notes require Nalco Company to maintain the following financial covenants: a maximum total leverage ratio, a senior secured leverage ratio, a minimum interest coverage ratio and a
maximum capital expenditures limitation. We were in compliance with all covenants at December 31, 2009.

Net proceeds from New Term Loan B and the Notes were used to repay the remaining $15.0 million balance of
the existing term loan A maturing on November 4, 2009, to repay $720.0 million of the existing term loan B maturing on November 4, 2010, and to redeem $475.0 million aggregate principal amount of senior notes due November 2011. Available
cash and net proceeds from Term Loan C were used to redeem 200.0 million aggregate principal amount of senior notes due November 2011 and the remaining $190.0 million aggregate principal amount of senior notes due November 2011. We refer
to these transactions, the issuance of the Notes, and our entry into the New Revolving Credit Facility, New Term Loan B and Term Loan C, collectively, as the Refinancing.

As a result of the Refinancing, we incurred a $20.5 million loss on extinguishment of debt, which is included in other income (expense), net. The loss was comprised of $10.4 million of accelerated
amortization of deferred financing costs related to the existing term loans and senior notes, a $9.2 million premium paid to redeem the $475.0 million of existing senior notes, and $0.9 million of other related charges.

In connection with the Refinancing, we recorded deferred financing costs of $54.7 million related to the New Revolving Credit Facility, New Term Loan B,
Term Loan C and the Notes, which will be amortized over their respective terms.

Senior credit facilities.    Our
senior credit facilities that were entered into in November 2003 initially included a revolving credit facility expiring on November 4, 2009, a $300.0 million term loan A facility (including an 88.0 million tranche) maturing on
November 4, 2009 and a $1,300.0 million term loan B facility maturing on November 4, 2010.

At December 31, 2009, the
outstanding balance of the term loan B facility was $167.0 million. Borrowings under the term loan B facility bear interest at a floating base rate plus an applicable margin of 0.75% with respect to base rate borrowings and 1.75% with respect to
LIBOR or Eurocurrency borrowings.

The senior credit facilities that were entered into in November 2003 contain a number of covenants that,
among other things, require Nalco Company to maintain the following financial covenants: a maximum total leverage ratio, a minimum interest coverage ratio and a maximum capital expenditures limitation. We were in compliance with all covenants at
December 31, 2009.

Senior discount notes, senior notes and senior subordinated
notes.    In November 2003, Nalco Company issued $665.0 million aggregate principal amount of 73/4% U.S. dollar-denominated senior notes due 2011, 200.0 million aggregate principal amount of 73/4% euro-denominated senior notes due 2011, $465.0 million aggregate
principal amount of 87/8% U.S. dollar-denominated
senior subordinated notes due 2013 and 200.0 million aggregate principal amount of 9% euro-denominated senior subordinated notes due 2013. As part of the Refinancing, Nalco Company redeemed the $665.0 million aggregate principal amount of
73/4% U.S. dollar-denominated senior notes due 2011
and the 200.0 million aggregate principal amount of 73/4% euro-denominated senior notes due 2011.

In January 2004,
our subsidiaries, Nalco Finance Holdings LLC and Nalco Finance Holdings Inc., issued $694.0 million aggregate principal amount at maturity of 9.0% senior discount notes due 2014. In December 2004, Nalco Finance Holdings LLC and Nalco Finance
Holdings Inc. redeemed a portion of the senior discount notes using proceeds from the initial public offering of common stock of Nalco Holding Company.

After the partial redemption, the aggregate principal amount at maturity of the notes declined to $460.8 million. Prior to February 1, 2009, interest accrued on the notes in the form of an increase
in the accreted value of such notes. The accreted value of each note increased from the date of issuance until February 1, 2009 at a rate of 9.0% per annum, reflecting the accrual of non-cash interest, such that the accreted value equals
the principal amount at maturity of $460.8 million. Cash interest payments on the notes became due and payable beginning in August 2009.

The indentures governing the senior subordinated notes and the senior discount notes limit our ability and
the ability of our restricted subsidiaries to:



| |  |  | incur additional indebtedness;
| | - |  | ------------------------------



| |  |  | pay dividends on or make other distributions or repurchase certain capital stock;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | make certain investments;

| |  |  | use assets as security in other transactions; and
| | - |  | -------------------------------------------------



| |  |  | sell certain assets or merge with or into other companies.
| | - |  | ----------------------------------------------------------

Subject to certain exceptions, the indentures governing the senior subordinated notes and the senior discount notes permit our restricted subsidiaries and us to incur additional indebtedness, including
secured indebtedness.

Local lines of credit.    Certain of our non-U.S. subsidiaries have lines of credit to
support local requirements. As of December 31, 2009, the aggregate outstanding balance under these local lines of credit was approximately $52.7 million. Certain of these lines of credit are equally and ratably secured with obligations under
our senior credit facilities.

Receivables facility.    Nalco Company entered into a three-year receivables
facility on June 22, 2007 that provides up to $160 million in funding from a commercial paper conduit sponsored by Bank of America, N.A., one of the lenders under Nalco Companys senior credit facilities, based on availability of eligible
receivables and satisfaction of other customary conditions.

Availability of funding under the receivables facility in a given month depends
primarily upon the outstanding trade accounts receivable balance at the end of the previous month. Aggregate availability is determined by using a formula that reduces the gross receivables balance by factors that take into account historical
default and dilution rates, excessive concentrations and average days outstanding and the costs of the facility. As of December 31, 2009, we had no outstanding borrowings under this facility, although there was $121.0 million of available
funding based on the amount of receivables eligible for financing as of November 30, 2009.

This facility is treated as a general
financing agreement resulting in the borrowings and related receivables being shown as liabilities and assets, respectively, on our consolidated balance sheet and the costs associated with the receivables facility being recorded as interest expense.

Our contractual obligations and commitments over the next several years are significant. Our primary source of liquidity will continue to be cash flow
generated from operations. In the period January 1, 2007 through December 31, 2009, our cumulative cash flow from operations was $1,200.3 million. We have availability under a $250 million revolving credit facility to assist us, if
required, in meeting our working capital needs and other contractual obligations. This multi-year revolving credit facility matures in May 2014. If our cash flow from operations is insufficient to fund our debt service and other obligations, we may
be forced to reduce or delay capital expenditures, seek additional capital or seek to restructure or refinance our indebtedness. At December 31, 2009, we had $231.6 million of borrowing capacity available under our revolving credit facility,
which reflects no outstanding borrowings and reduced availability as a result of $18.4 million in outstanding letters of credit.

We believe
that cash flow generated from operations and our borrowing capacity will be adequate to meet our obligations and business requirements. Our ability to fund these items and to reduce debt may be affected by general economic, financial, competitive,
legislative and regulatory factors, and the cost of litigation claims, among other things.

Recent Accounting Pronouncements

In September 2006, the FASB issued authoritative guidance for fair value measurements, which defines fair value, establishes a framework for measuring fair
value, and expands disclosures about fair value measurements in the financial statements. In February 2008, the FASB issued authoritative guidance that delayed by one year the effective date for applying the guidance for fair value measurements to
nonfinancial assets and nonfinancial liabilities measured at fair value on a nonrecurring basis. We adopted the authoritative guidance for fair value measurements for our nonfinancial assets and nonfinancial liabilities measured on a nonrecurring
basis effective January 1, 2009, which did not have a material impact on our financial statements.

In December 2007, the FASB revised
the authoritative guidance for business combinations. The guidance retains the underlying concepts of earlier authoritative guidance in that all business combinations are required to be accounted for under the acquisition method of accounting, but
changes the method of applying the acquisition method in a number of significant aspects. We adopted the revised authoritative guidance effective January 1, 2009, which did not have a material impact on our financial statements.

In December 2007, the FASB issued authoritative guidance that amends earlier guidance for consolidation procedures for consistency with the requirements of
the revised authoritative guidance for business combinations. The guidance also requires noncontrolling interests to be separately presented as a component of equity in the consolidated balance sheet and the amount of net earnings attributable to
noncontrolling interests to be included in consolidated net earnings on the face of the income statement. We adopted the accounting provisions of the guidance on a prospective basis effective January 1, 2009. In addition, we adopted the
presentation and disclosure requirements of the guidance on a retrospective basis in the first quarter of 2009.

In March 2008, the FASB
issued authoritative guidance that amends and expands the disclosure requirements of earlier guidance with regard to derivatives and hedging activities. We adopted the guidance effective January 1, 2009. See Note 17 of our consolidated
financial statements included in Item 8 of this Annual Report.

In December 2008, the FASB issued authoritative guidance to require
additional disclosures about assets held in an employers pension and other postretirement benefit plans. The guidance is effective for fiscal years ending after December 15, 2009. The additional disclosures are included in Note 14 of our
consolidated financial statements included in Item 8 of this Annual Report. Adoption of this guidance did not have an impact on our financial position, results of operations or cash flows.

##### Table of Contents

In April 2009, the FASB issued additional authoritative guidance about (1) measuring the fair value of
financial instruments when the markets become inactive and quoted prices may reflect distressed transactions, and (2) recording impairment charges on investments in debt instruments. We adopted the guidance in the second quarter of 2009,
which did not have a material impact on our financial statements.

In May 2009, the FASB issued authoritative guidance that establishes
general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. We adopted the guidance in the second quarter of 2009, which did not
have an impact on our financial statements.

In June 2009, the FASB issued authoritative guidance that eliminates the qualifying special
purpose entity concept, changes the requirements for derecognizing financial assets and requires enhanced disclosures about transfers of financial assets. The guidance also revises earlier guidance for determining whether an entity is a variable
interest entity, requires a new approach for determining who should consolidate a variable interest entity, changes when it is necessary to reassess who should consolidate a variable interest entity, and requires enhanced disclosures related to an
enterprises involvement in variable interest entities. The guidance is effective for the first annual reporting period that begins after November 15, 2009. We are currently evaluating the effects that the guidance may have on our
financial statements.

In June 2009, the FASB issued authoritative guidance that provides for the FASB Accounting Standards Codification (the
Codification) to become the single official source of authoritative, nongovernmental U.S. generally accepted accounting principles (GAAP). The Codification did not change GAAP but reorganizes the literature. The guidance was
effective for interim and annual periods ending after September 15, 2009, and we adopted the guidance in our financial statements for the third quarter of 2009. Adoption of this guidance did not have an impact on our financial position, results
of operations or cash flows.

In August 2009, the FASB issued authoritative guidance on measuring the fair value of liabilities. The guidance
clarifies that in circumstances in which a quoted price in an active market for the identical liability is not available, an entity is required to use one or more of the following valuation techniques to measure fair value: (1) the quoted price
of the identical liability when traded as an asset, (2) quoted prices of similar liabilities or similar liabilities when traded as assets, and (3) an income approach, such as a present value technique, or a market approach, such as a
technique that is based on the amount at the measurement date that the entity would pay to transfer the identical liability or would receive to enter into the identical liability. The guidance was effective for the first interim or annual reporting
period beginning after its issuance (our fourth quarter of 2009). Adoption of the guidance did not have a material impact on our financial statements.

In October 2009, the FASB issued authoritative guidance that amends earlier guidance addressing the accounting for contractual arrangements in which an entity provides multiple products or services (deliverables) to a customer. The
amendments address the unit of accounting for arrangements involving multiple deliverables and how arrangement consideration should be allocated to the separate units of accounting, when applicable, by establishing a selling price hierarchy for
determining the selling price of a deliverable. The selling price used for each deliverable will be based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated
selling price if neither vendor-specific nor third-party evidence is available. The amendments also require that arrangement consideration be allocated at the inception of an arrangement to all deliverables using the relative selling price method.
The guidance is effective for fiscal years beginning on or after June 15, 2010, with earlier application permitted. We are currently evaluating the effects that the guidance may have on our financial statements.

In October 2009, the FASB issued authoritative guidance that amends earlier guidance for revenue arrangements that include both tangible products and
software elements. Tangible products containing software components and nonsoftware components that function together to deliver the tangible

products essential functionality are no longer within the scope of guidance for recognizing revenue from the sale of software, but would be accounted for in accordance with other
authoritative guidance. The guidance is effective for fiscal years beginning on or after June 15, 2010, with earlier application permitted. We are currently evaluating the effects that the guidance may have on our financial statements.



|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

We are subject to inherent risks attributed to operating in a global economy. We may utilize derivative financial instruments as necessary to manage foreign currency exchange rate risks. We manage foreign
currency exchange risk arising from financial activities pursuant to our corporate guidelines. Forward contracts and, occasionally, swaps and options are utilized to protect these cash flows from adverse movements in exchange rates, and we account
for these instruments by marking them to market at each balance sheet date. We may also employ hedge accounting as permitted by authoritative guidance issued by the FASB.In addition, we use certain foreign currency debt as a hedge of the
foreign currency exposure of a portion of our net investment in foreign operations.

Upon issuance, we designated the
200.0 million aggregate principal amount of 73/4% senior notes due 2011, the 200.0 million aggregate principal amount of 9% senior subordinated notes due 2013, and an 88.0 million term loan as a hedge of our net investment in subsidiary companies whose assets,
liabilities, and operations are measured using the euro as their functional currency. Because of the high degree of effectiveness between the hedging instruments and the exposure being hedged, fluctuations in the value of the euro-denominated debt
due to exchange rate changes are offset by changes in the net investment. Accordingly, changes in the value of the euro-denominated debt are recognized in foreign currency translation adjustment, a component of accumulated other comprehensive
income, to offset changes in the value of our net investment in subsidiary companies whose financial statements are measured using the euro as their functional currency. The carrying value of euro-denominated debt designated as a net investment
hedge was $287.7 million at December 31, 2009.

We formally assess, on a quarterly basis, whether the euro-denominated debt is
effective at offsetting changes in the value of the underlying exposure. For the year ended December 31, 2009, we recorded a $22.4 million non-cash pretax loss in the accumulated foreign currency translation adjustment account related to this
hedge. No hedge ineffectiveness was recorded in income.

We also manage operational (transactional) foreign currency risk, particularly in
emerging markets, by closely managing both pricing and raw material sourcing. Risks associated with foreign exchange translation exposures are not hedged.

We have exposure to fluctuations in foreign currency exchange rates. Based on our derivative foreign currency instruments outstanding at December 31, 2009 and 2008, a 10% strengthening or weakening
in the value of the U.S. dollar relative to the currencies in which those derivative foreign currency instruments are denominated would result in a gain or loss in fair values of less than $5.8 million and $2.7 million for the respective year.

At December 31, 2009, we had $1,224.1 million of variable rate debt. A 1% increase in the average interest rate would increase future
interest expense by approximately $12.2 million per year.

Our sensitivity analysis of the effects of the changes in interest rates and
foreign currency exchange rates do not reflect the effect of such changes on the related hedged transactions or on other operating transactions. The analysis also does not factor in a potential change in the level of variable rate borrowings or
derivative instruments outstanding that could take place if these hypothetical conditions prevailed.

We are exposed to credit loss in the
event of nonperformance by the other party to the derivative financial instruments. We limit this exposure by entering into agreements directly with a number of major financial institutions that meet our credit standards and that are expected to
satisfy fully their obligations under the contracts. We view derivative financial instruments as a risk management tool and do not use them for speculative or trading purposes.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of Nalco Holding Company

We have audited the accompanying consolidated balance sheets of Nalco Holding Company and subsidiaries as of December 31, 2009 and 2008, and the related consolidated statements of operations, equity,
and cash flows for each of the three years in the period ended December 31, 2009. Our audits also included the financial statement schedules listed in the Index at Item 15(a)(2). These financial statements and schedules are the
responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements and schedules based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Nalco Holding
Company and subsidiaries at December 31, 2009 and 2008, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2009, in conformity with U.S. generally accepted
accounting principles. Also, in our opinion, the related financial statement schedules, when considered in relation to the basic financial statements taken as a whole, present fairly in all material respects the information set forth therein.

As described in Note 2 to the consolidated financial statements, effective January 1, 2009, the Company adopted new rules regarding the
accounting, presentation and disclosure requirements for noncontrolling interests.

We also have audited, in accordance with the standards of
the Public Company Accounting Oversight Board (United States), Nalco Holding Company and subsidiaries internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control  Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2010 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of Nalco Holding Company

We have audited Nalco Holding Company and subsidiaries internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control  Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Nalco Holding Company and subsidiaries management is responsible for maintaining effective internal control over financial reporting,
and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Managements Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the
companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material
respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that,
in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject
to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Nalco Holding Company and Subsidiaries

Notes to Consolidated Financial Statements

(dollars in millions, except per share amounts)

December 31, 2009

1.    Description of Business and Change in Ownership

Description of Business

We are engaged in
the worldwide manufacture and sale of highly specialized service chemical programs. This includes production and service related to the sale and application of chemicals and technology used in water treatment, pollution control, energy conservation,
oil production and refining, steelmaking, papermaking, mining, and other industrial processes.

Change in Ownership

On November 4, 2003, Nalco Holding Companys indirect subsidiary, Nalco Holdings LLC (the Buyer), a newly formed entity controlled by
affiliates of The Blackstone Group, L.P., Apollo Management, L.P., and The Goldman Sachs Group, Inc. (collectively, the Sponsors), pursuant to a Stock Purchase Agreement (as amended, the Stock Purchase Agreement) with Suez
S.A. (Suez) and certain of its affiliates, acquired the net assets of Ondeo Nalco Group (as defined below) for $4,127.1 million, including direct costs of the acquisition of $125.6 million, excluding assumed debt of $30.2 million, and
subject to certain closing and post-closing adjustments (the Acquisition).

The Ondeo Nalco Group (the Predecessor)
included Ondeo Nalco Company and subsidiaries (ONC) and certain subsidiaries of Nalco International SAS (NIS) plus Calgon Europe Limited (UK), owned by Degremont (a former related party). Ondeo Industrial Solutions North
America, a subsidiary of ONC, was excluded from the Predecessor, as the Buyer did not acquire it.

2.    Summary of
Significant Accounting Policies

Basis of Presentation

All intercompany balances and transactions are eliminated. Investments in companies or partnerships in which we do not have control, but have the ability to exercise significant influence over operating
and financial policies, are reported using the equity method.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make
estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates.

Reclassifications

Certain reclassifications have been made to the consolidated statements of operations for the years ended December 31, 2008 and 2007 to conform to the
current year presentation.

These reclassifications had no effect on net earnings reported for any period.

Foreign Currency Translation

Local
currencies are the functional currencies for most foreign operations. Their balance sheets and income statements are translated at current and average exchange rates, respectively, with any resulting translation adjustments included in the currency
translation adjustment account in shareholders equity.

2.    Summary of Significant Accounting Policies (continued)



The financial statements of any foreign subsidiaries that operate in highly inflationary environments are translated using a combination of current, average, and historical exchange rates, with
the resulting translation impact included in results of operations. Exchange adjustments resulting from transactions executed in different currencies are included in other income (expense), net in the statements of operations.

Concentration of Credit Risk

Credit risk
represents the accounting loss that would be recognized at the reporting date if counterparties failed to perform as contracted. We believe the likelihood of incurring material losses due to concentration of credit risk is remote. The principal
financial instruments subject to credit risk are as follows:

Cash and Cash Equivalents

A formal policy exists of placing these instruments in investment grade companies and institutions and limiting the size of an investment with any single
entity.

Accounts Receivable

A large number of customers in diverse industries and geographies, as well as the practice of establishing reasonable credit lines, limits credit risk. The allowance for doubtful accounts is adequate to cover potential credit risk losses.

Foreign Exchange Contracts and Derivatives

Formal policies exist, which establish credit limits and investment grade credit criteria of A or better for all counterparties.

Cash and Cash Equivalents

Cash and cash equivalents include all cash balances and highly
liquid investments with original maturities of three months or less.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are carried at their face amounts less an allowance for doubtful accounts. On a periodic basis, we evaluate our
accounts receivable and establish the allowance for doubtful accounts based on a combination of specific customer circumstances and credit conditions and based on a history of write-offs and collections. Our policy is generally to not charge
interest on trade receivables after the invoice becomes past due. A receivable is considered past due if payments have not been received within agreed upon invoice terms. Write-offs are recorded at the time a customer receivable is deemed
uncollectible.

Inventory Valuation

Inventories are valued at the lower of cost or market. Approximately 64% of the inventories at both December 31, 2009 and 2008 are valued using the average cost or first-in, first-out (FIFO) method. The remaining inventories are valued
using the last-in, first-out (LIFO) method. Reported inventory amounts would have been $9.7 million and $30.5 million higher at December 31, 2009 and 2008, respectively, if the FIFO method of accounting had been used for all inventories.

The LIFO method is used only in the United States. Most of the countries outside of the United States where we have subsidiaries do not
permit the use of the LIFO method. In those countries where its use is permitted, we have not adopted the LIFO method of inventory valuation because the value of the inventories in those countries is not significant.

Goodwill and Other Intangible Assets

We assess the recoverability of goodwill and other intangible assets with indefinite lives annually or whenever events or changes in circumstances indicate
that the carrying amount of the asset may not be fully recoverable.

We have defined our operating segments as our reporting units. We use a
two-step process to test goodwill for impairment. First, the reporting units fair value is compared to its carrying value. Fair value is estimated using a discounted cash flow approach. If a reporting units carrying amount exceeds its
fair value, an indication exists that the reporting units goodwill may be impaired, and the second step of the impairment test would be performed, which is used to measure the amount of the impairment loss, if any. In the second step, the
implied fair value of the reporting units goodwill is determined by allocating the reporting units fair value to all of its assets and liabilities other than goodwill in a manner similar to a purchase price allocation. The implied fair
value of the goodwill that results from the application of this second step is then compared to the carrying amount of the goodwill and an impairment charge would be recorded for the difference if the carrying value exceeds the implied fair value of
the goodwill.

We test the carrying value of other intangible assets with indefinite lives by comparing the fair value of the intangible
assets to the carrying value. Fair value is estimated using a relief of royalty approach, a discounted cash flow methodology.

We amortize
most customer relationship intangibles using a declining-balance method over an estimated useful life of 16 years to reflect the pattern in which the economic benefits of that asset are realized. This amortization method considers the expected rate
of customer attrition, which was based on historical attrition data that was also used in estimating the fair value of the customer relationship intangible acquired.

The straight-line method is used for all other assets subject to amortization. Patents and developed technology are primarily being amortized over an estimated useful life of 10 years.

Deferred Financing Costs

Deferred
financing costs are incurred to obtain long-term financing and are amortized using the effective interest method over the term of the related debt. The amortization of deferred financing costs, which is classified in interest expense in the
statement of operations, was $7.7 million, $9.7 million and $10.1 million for the years ended December 31, 2009, 2008 and 2007, respectively.

Asset Retirement Obligations

The fair value of a liability for an asset retirement obligation is recognized in the period in
which it is incurred. The liability is adjusted to its present value in subsequent periods as accretion expense is recorded. The corresponding asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset and
depreciated over the assets useful life.

The liability for asset retirement obligations was $14.7 million and $4.8 million at
December 31, 2009 and 2008, respectively, for remediation and demolition activities at certain manufacturing sites where legal obligations associated with the retirement of tangible long-lived assets exist and potential settlement dates can be
determined. The liability for other asset retirement obligations cannot currently be measured as the retirement dates are not yet determinable. We will recognize the liability when sufficient information exists to estimate potential settlement
dates. The increase in the liability during 2009 was mostly due to additional obligations recognized and revisions in estimated cash flows required to settle certain obligations.

Income Taxes

Income taxes are recognized during the period in which transactions enter
into the determination of financial statement income, with deferred income taxes being provided for the tax effect of temporary differences between the carrying amount of assets and liabilities and their tax bases.



65

##### Table of Contents

2.    Summary of Significant Accounting Policies (continued)



Deferred income taxes are provided on the undistributed earnings of foreign subsidiaries except to the
extent such earnings are considered to be permanently reinvested in the subsidiary. In cases where available foreign tax credits will not offset income taxes, appropriate provisions are included in the consolidated statement of operations.

Valuation allowances are determined based on the realizability of the deferred tax assets. Relevant factors to determine the realizability of
the assets include future taxable income, the expected timing of the reversal of temporary differences, tax planning strategies and the expiration dates of the various tax attributes. Valuation allowances are established for those assets that are
determined to be more likely than not to expire without benefit, or for which income of the proper character is not anticipated.

The effect
of a valuation allowance for a deferred tax asset that is expected to originate in the current year is included in the annual effective tax rate for the year. The effect of a change in the beginning-of-the-year balance of a valuation allowance
resulting from a change in judgment about the realizability of the related deferred tax asset in future years is recognized in the interim period in which the change occurs.

We record liabilities for income tax uncertainties in accordance with the recognition and measurement criteria prescribed in authoritative guidance issued by the Financial Accounting Standards Board
(FASB). The tax benefits and related reserves are measured throughout the year, taking into account new legislation, regulations, case law and audit results. We recognize income tax-related interest and penalties within the income tax
provision.

Derivative Instruments

Derivatives are recognized as either assets or liabilities in the balance sheets at fair value.

Revenue Recognition

Revenue from sales of products, including amounts billed to customers for shipping and handling costs, is recognized at the time:
(1) persuasive evidence of an arrangement exists, (2) ownership and all risks of loss have been transferred to the buyer, which is generally upon shipment, (3) the price is fixed and determinable, and (4) collectibility is
reasonably assured. Revenue from services is recognized when the services are provided to the customer.

Cost of Product Sold

Cost of product sold includes the cost of inventory (materials and conversion costs) sold to customers, shipping and handling costs, and
certain warehousing costs. It also includes inbound freight charges, purchasing and receiving costs, packaging, quality assurance costs, internal transfer costs, and other costs of our distribution network. It also includes supply chain
administration, safety, health and environmental administration, and the costs of labor for services provided, whether as saleable services or as part of a multiple deliverables arrangement.

Selling, Administrative and Research Expenses

Selling expenses, which include the cost of our sales force and marketing staff and their related expenses, were $880.2 million, $972.4 million and $915.1 million for the years ended December 31, 2009, 2008 and 2007, respectively.

Administrative expenses primarily represent the cost of support functions, including information technology, finance, human resources and
legal, as well as expenses for support facilities, executive management and management incentive plans. Administrative expenses were $255.4 million, $204.1 million and $225.2 million for the years ended December 31, 2009, 2008 and 2007,
respectively.

Research and development expenses represent the cost of our research and development personnel and their related expenses,
including research facilities in the United States, the Netherlands and Singapore.

Research and development expenses, totaled $74.6 million, $73.5 million and $65.8 million for the years ended December 31, 2009, 2008 and 2007, respectively. Research and development costs
are charged to expense as incurred.

Recent Accounting Pronouncements

In September 2006, the FASB issued authoritative guidance for fair value measurements, which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value
measurements in the financial statements. In February 2008, the FASB issued authoritative guidance that delayed by one year the effective date for applying the guidance for fair value measurements to nonfinancial assets and nonfinancial liabilities
measured at fair value on a nonrecurring basis. We adopted the authoritative guidance for fair value measurements for our nonfinancial assets and nonfinancial liabilities measured on a nonrecurring basis effective January 1, 2009, which did not
have a material impact on our financial statements.

In December 2007, the FASB revised the authoritative guidance for business combinations.
The guidance retains the underlying concepts of earlier authoritative guidance in that all business combinations are required to be accounted for under the acquisition method of accounting, but changes the method of applying the acquisition method
in a number of significant aspects. We adopted the revised authoritative guidance effective January 1, 2009, which did not have a material impact on our financial statements.

In December 2007, the FASB issued authoritative guidance that amends earlier guidance for consolidation procedures for consistency with the requirements of the revised authoritative guidance for business
combinations. The guidance also requires noncontrolling interests to be separately presented as a component of equity in the consolidated balance sheet and the amount of net earnings attributable to noncontrolling interests to be included in
consolidated net earnings on the face of the income statement. We adopted the accounting provisions of the guidance on a prospective basis effective January 1, 2009. In addition, we adopted the presentation and disclosure requirements of the
guidance on a retrospective basis in the first quarter of 2009.

In March 2008, the FASB issued authoritative guidance that amends and expands
the disclosure requirements of earlier guidance with regard to derivatives and hedging activities. We adopted the guidance effective January 1, 2009. See Note 17.

In December 2008, the FASB issued authoritative guidance to require additional disclosures about assets held in an employers pension and other postretirement benefit plans. The guidance is effective
for fiscal years ending after December 15, 2009. The additional disclosures are included in Note 14. Adoption of this guidance did not have an impact on our financial position, results of operations or cash flows.

In April 2009, the FASB issued additional authoritative guidance about (1) measuring the fair value of financial instruments when the markets become
inactive and quoted prices may reflect distressed transactions, and (2) recording impairment charges on investments in debt instruments. We adopted the guidance in the second quarter of 2009, which did not have a material impact on our
financial statements.

In May 2009, the FASB issued authoritative guidance that establishes general standards of accounting for and disclosure
of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. We adopted the guidance in the second quarter of 2009, which did not have an impact on our financial statements.

In June 2009, the FASB issued authoritative guidance that eliminates the qualifying special purpose entity concept, changes the requirements
for derecognizing financial assets and requires enhanced disclosures about transfers of financial assets. The guidance also revises earlier guidance for determining whether an entity is a variable interest entity, requires a new approach for
determining who should consolidate a variable interest entity, changes when it is necessary to reassess who should consolidate a

variable interest entity, and requires enhanced disclosures related to an enterprises involvement in variable interest entities. The guidance is effective for the first annual
reporting period that begins after November 15, 2009. We are currently evaluating the effects that the guidance may have on our financial statements.

In June 2009, the FASB issued authoritative guidance that provides for the FASB Accounting Standards Codification (the Codification) to become the single official source of authoritative,
nongovernmental U.S. generally accepted accounting principles (GAAP). The Codification did not change GAAP but reorganizes the literature. The guidance was effective for interim and annual periods ending after September 15, 2009, and
we adopted the guidance in our financial statements for the third quarter of 2009. Adoption of this guidance did not have an impact on our financial position, results of operations or cash flows.

In August 2009, the FASB issued authoritative guidance on measuring the fair value of liabilities. The guidance clarifies that in circumstances in which a
quoted price in an active market for the identical liability is not available, an entity is required to use one or more of the following valuation techniques to measure fair value: (1) the quoted price of the identical liability when traded as
an asset, (2) quoted prices of similar liabilities or similar liabilities when traded as assets, and (3) an income approach, such as a present value technique, or a market approach, such as a technique that is based on the amount at the
measurement date that the entity would pay to transfer the identical liability or would receive to enter into the identical liability. The guidance was effective for the first interim or annual reporting period beginning after its issuance (our
fourth quarter of 2009). Adoption of the guidance did not have a material impact on our financial statements.

In October 2009, the FASB
issued authoritative guidance that amends earlier guidance addressing the accounting for contractual arrangements in which an entity provides multiple products or services (deliverables) to a customer. The amendments address the unit of accounting
for arrangements involving multiple deliverables and how arrangement consideration should be allocated to the separate units of accounting, when applicable, by establishing a selling price hierarchy for determining the selling price of a
deliverable. The selling price used for each deliverable will be based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither
vendor-specific nor third-party evidence is available. The amendments also require that arrangement consideration be allocated at the inception of an arrangement to all deliverables using the relative selling price method. The guidance is effective
for fiscal years beginning on or after June 15, 2010, with earlier application permitted. We are currently evaluating the effects that the guidance may have on our financial statements.

In October 2009, the FASB issued authoritative guidance that amends earlier guidance for revenue arrangements that include both tangible products and
software elements. Tangible products containing software components and nonsoftware components that function together to deliver the tangible products essential functionality are no longer within the scope of guidance for recognizing revenue
from the sale of software, but would be accounted for in accordance with other authoritative guidance. The guidance is effective for fiscal years beginning on or after June 15, 2010, with earlier application permitted. We are currently
evaluating the effects that the guidance may have on our financial statements.

3.    Acquisitions and Divestitures

In March 2009, we acquired the assets of Crossbow Water, a regional high-purity water and water pre-treatment company, for $22.1 million. The purchase
agreement provides for up to $21.0 million of additional contingent consideration based upon the achievement of specified revenue targets. The purchase price, including the estimated fair value of the additional contingent consideration, exceeded
the fair value of the net tangible assets acquired by $30.3 million, which was allocated to goodwill and other intangible assets.

During
2008, we purchased 100% of the outstanding shares of TIORCO, Inc., a company engaged in the enhanced oil recovery business, for $8.5 million, net of cash acquired. The purchase agreement included a provision for two contingent payments. The first
payment of $3.1 million was paid during 2008, and the second payment, which was paid in 2009, was $4.8 million. Both payments were accounted for as additional purchase price. The purchase price, including the contingent payments, exceeded the fair
value of the net tangible assets acquired by $15.8 million, which was allocated to goodwill and other intangible assets.

In August 2008, we
purchased the assets of G&L Soap Injection Enterprise, LLC and Six Degrees, LLC, companies engaged in the business of treating gas and oil wells, for $7.0 million. The purchase price exceeded the fair value of the net tangible assets acquired by
$6.3 million, which was allocated to goodwill and other intangible assets. The purchase agreement included a provision for three contingent payments totaling $2.0 million that are earned if certain targets are achieved in the years 2009, 2010 and
2011. The 2009 target was achieved, and a payment of $0.7 million was made in 2009, which was accounted for as additional purchase price.

Other small business acquisitions were made during 2008 for a combined purchase price of $3.1 million, net of cash acquired. The purchase price exceeded the fair value of the net tangible assets acquired by $2.1 million, which was allocated
to goodwill.

In September 2008, we completed the sale of our Finishing Technologies surface treatment business to Chemetall Corp., a
subsidiary of Rockwood Holdings, Inc. Proceeds from the sale were $74.1 million, net of selling and other cash expenses of $0.9 million, and resulted in a gain of $38.1 million before income taxes. A plant in Jackson, Michigan, dedicated to the
Finishing Technologies business, was included in the sale, along with dedicated Finishing Technologies sales, service, marketing, research and supply chain employees. The sale also included products, goodwill, customer relationships and other
related assets. The Finishing Technologies business was not presented as a discontinued operation because its operations and cash flows were not clearly distinguished from the rest of the entity. On an after-tax basis, the transaction increased
diluted earnings per share by 11 cents for the year ended December 31, 2008.

On December 10, 2007 (the Effective Date),
we purchased an 87.5% interest in Mobotec USA, Inc. (Mobotec), a leading provider of combustion optimization and emission reduction capabilities, including engineering, equipment and chemistry for industrial and utility boilers. We
accounted for the acquisition as a purchase, and the results of Mobotecs operations were included in our consolidated financial statements from the date of acquisition. The purchase price was $27.9 million, net of $6.4 million of cash
acquired. The purchase price is subject to certain adjustments as defined by the share purchase agreement. The purchase price exceeded the fair value of the net tangible assets acquired by $39.1 million, which was allocated to goodwill and other
intangible assets.

Concurrent with the purchase of the 87.5% interest in Mobotec, we entered into an agreement with the minority shareholder
that provides us with two options to purchase the remaining shares of Mobotec. Each option provides us with the right to purchase 50% of the remaining shares of Mobotec. The first option and second option can be exercised no earlier than two years
and four years, respectively, after the Effective Date. Both options expire five years after the Effective Date. The exercise price for each option is based on Mobotecs EBITDA, as defined in the agreement, for the four calendar quarters that
precede the exercise date. The agreement also provides the minority shareholder with two options to sell the remaining shares of Mobotec to us, with terms identical to our purchase options.

The pro forma impact as if the aforementioned acquisitions had occurred at the beginning of the respective years is not significant.

4.    Securitization of Accounts Receivable

We have an accounts receivable securitization facility with a commercial paper conduit sponsored by one of the lenders under our senior credit facilities
that provides up to $160.0 million in funding, based on availability of eligible receivables and satisfaction of other customary conditions, and which expires in June 2010.

Under the facility, Nalco Company (the Seller), a wholly owned indirect subsidiary of the Company, transfers all eligible trade accounts receivable (the Receivables) to a bankruptcy-remote, wholly owned,
special purpose limited liability company (the Transferor). Pursuant to a Receivables Transfer Agreement, the Transferor then transfers an undivided interest in the Receivables to the commercial paper conduit or the related bank sponsor (the
Transferees) in exchange for cash.

The financing fee charged by the Transferees under the facility is based on the amount funded and the
conduits cost of funds for issuing commercial paper plus a margin that varies based on the leverage ratio as calculated under our senior credit facilities. The Transferees also charge a facility fee, which varies based on the same ratio, on
102% of the total funding commitment under the facility. Nalco Company services, administers and collects the Receivables, for which it receives a monthly servicing fee of 1% per annum of the average daily outstanding balance of Receivables.

Availability of funding under the facility depends primarily upon the outstanding Receivables balance from time to time. The facility may be
terminated for, among other reasons, material breaches of representations and warranties, bankruptcies of the Seller or the Transferor, a judgment or order for the payment of money rendered against the Transferor, cross-defaults to our other debt,
or breach of specified financial covenants. We are currently in compliance with these covenants.

The facility is accounted for as a secured
borrowing, resulting in the funding and related Receivables being shown as liabilities and assets, respectively, on our consolidated balance sheet and the costs associated with the facility being recorded as interest expense. We had no outstanding
borrowings at December 31, 2009 and $98.0 million of outstanding borrowings at December 31, 2008 under the facility.

We performed our annual impairment test during the fourth quarter 2009 and 2008. As a result of a significant decline in our
stock price in the fourth quarter 2008 and a sharp deterioration in conditions within the paper industry and the general economy during that quarter, our impairment test indicated the potential for impairment in our Paper Services reporting unit. We
performed the second step of the goodwill impairment test and determined that an impairment of goodwill existed. Accordingly, we recorded a non-cash goodwill impairment charge of $544.2 million in the fourth quarter 2008, reducing the goodwill
balance of our Paper Services reporting unit to zero.

8.    Contribution Agreement With Profit-Sharing Trust and Reimbursement Agreement with Suez

The
Predecessor previously had an Employee Stock Ownership Plan (ESOP), which gave most U.S. employees an additional opportunity to share in the ownership of the Predecessors stock. Preferred shares were allocated to eligible employees
based on a percentage of pretax earnings.

At the inception of the ESOP, the Predecessor and a trustee entered into a trust agreement,
constituting the ESOP Trust, to fund benefits under the Predecessors ESOP. As part of its acquisition of Nalco Chemical Company in November 1999, Suez purchased from the trustee all of the issued and outstanding Series B ESOP Convertible
Preferred Stock at a price of $1,060 per share. The trustee credited proceeds from the sale of allocated shares to participants accounts. Under the terms of an agreement (the Contribution Agreement), the Predecessor and the ESOP
trustee agreed that the trustee would use proceeds from the sale of shares held in the loan suspense account to repay the outstanding principal and accrued interest on the ESOP loans. It was also agreed that all proceeds remaining after the
repayment of the loans and accrued interest would be allocated to participants accounts. In return, the Predecessor agreed to make contributions to the Profit Sharing, Investment and Pay Deferral Plan Trust (the Trust) on or before
December 31, 2010, having a present value equal to $124.6 million, the outstanding principal and accrued interest paid on the ESOP loans. The plan was amended effective January 1, 2003 to also permit matching contributions under the
Companys 401(k) plan to count as contributions to the Trust. The Contribution Agreement provides for specified minimum annual contributions to be made to the Trust, with interest accruing on the outstanding contribution balance at an annual
rate of 8.5% compounded monthly. The contribution commitment becomes due and payable in its entirety if one or more events that are specified in the Contribution Agreement occur.

Pursuant to the Stock Purchase Agreement, we entered into an agreement (the Reimbursement Agreement) with Suez on November 4, 2003, whereby Suez shall reimburse us for all contributions
we make to the Trust in order to satisfy our obligations under the Contribution Agreement. As part of the allocation of the Acquisition purchase price, we recorded a receivable from Suez of $112.7 million, equivalent to our recorded liability to the
Trust, and recorded a $115.0 million unearned employee profit sharing asset, which was being amortized to reflect profit sharing and 401(k) matching contribution expenses in the period earned by employees. Interest accretes on the Suez receivable at
the same rate that it accretes on our obligation to the Trust. The receivable does not have specific due dates, but under the terms of the Reimbursement Agreement, Suez is required to reimburse us immediately after we make any contributions to the
Trust. The receivable is not secured by any Suez asset. However, under the terms of a sublease agreement with Leo Holding Company (Leo), a subsidiary of Suez, whereby we sublease our corporate headquarters and research facility from Leo,
if Suez fails to pay any of the payments it is required to make under the Reimbursement Agreement, we have the right to set off such overdue amounts against the rent due under the sublease agreement (see Note 13). Conversely, under the terms of the
Reimbursement Agreement, if we fail to pay when due any sublease rent (as defined in the sublease agreement), Suez shall have the right to reduce its reimbursement obligations to us pursuant to the Reimbursement Agreement by an amount equal to such
shortfall.

The unamortized unearned employee profit sharing asset of $22.1 million as of December 31, 2008 was fully amortized in 2009,
and an additional $7.4 million of profit sharing and 401(k) matching contribution

Agreement with Suez (continued)



expenses were accrued in the period. The receivable from Suez and the payable to the Trust were $14.6 million and $23.0 million, respectively, at December 31, 2009. Because Suez has been
reimbursing us for all payments that we have made toward satisfying our obligations under the Contribution Agreement, expenses related to the Contribution Agreement had been non-cash in nature. Because our profit sharing and 401(k) matching
contribution expenses for 2009 exceeded the remaining Contribution Agreement obligations, those excess expenses and future years expenses will require the use of cash.

Contributions to the Trust, profit sharing and 401(k) matching contribution expenses, and expenses recorded related to the Contribution Agreement are as follows:

9.    Property, Plant, and Equipment

Property, plant, and equipment (including major improvements) are recorded at cost. Depreciation of buildings and equipment is calculated
over their estimated useful lives generally using the straight-line method. We classify depreciation expense in our consolidated statements of operations as cost of product sold or selling, administrative and research expenses consistent with the
utilization of the underlying assets. Total depreciation expense for the years ended December 31, 2009, 2008 and 2007 was $142.3 million, $136.6 million and $132.3 million, respectively.

The estimated useful lives of the major classes of depreciable assets are as follows: buildings  33 to 40 years; software  5 years; equipment
 3 to 15 years.

Property, plant, and equipment consist of the following:

These deferred tax assets and liabilities are classified in the balance sheet based on the balance sheet
classification of the related assets and liabilities.

Nalco Holding Company and its subsidiaries file income tax returns in the U.S. federal
jurisdiction, various states and foreign jurisdictions, as required. With few exceptions, we are no longer subject to U.S. federal, state and local, or foreign income tax examinations by tax authorities for periods prior to 2004. To the extent that
we are subject to additional tax assessments greater than $150,000 that relate to tax periods before November 4, 2003, we are indemnified by our former shareholder, Suez, and therefore have recorded a receivable for the related indemnity claim.

Authoritative guidance issued by the FASB clarifies the accounting for uncertainty in income taxes recognized in an enterprises

As of December 31, 2009, full recognition of the $8.7 million of tax benefits not previously recognized would have
resulted in a reduction of the Suez receivable of $1.9 million and a favorable impact to the income tax provision of $6.8 million.

No provision has been made for United States or foreign income taxes related to approximately $368.8 million of
undistributed earnings of foreign subsidiaries at December 31, 2009, as we consider these earnings to be permanently reinvested. It is not practicable to estimate the additional income taxes and applicable withholding tax that would be payable
on the remittance of such undistributed earnings.

At the end of 2007, we were carrying forward United States federal net operating losses of
approximately $144.9 million ($50.7 million tax effect) expiring between 2024 and 2027. These losses were partly the result of deducting rather than crediting certain foreign taxes. The additional tax benefit of crediting the foreign taxes was
reported in our balance sheet at December 31, 2007 as a deferred tax asset of $35.4 million, offset by a full valuation allowance. Because of a change in our U.S. tax position in 2008, we have amended the previous U.S. tax returns to realize
the tax benefits of crediting foreign taxes and have credited foreign taxes in 2008 and 2009. Conversion of the previous foreign tax deductions to credits reduced the net operating loss carryforward, and the remaining federal net operating loss
carryforward was fully consumed in 2008. Our balance sheet continues to report state and local tax loss carryforwards.

The U.S. foreign tax
credit carryforward has increased to $73.6 million. The credits have a ten-year carryforward period, and will expire between 2015 and 2020 if not utilized. We assessed the realizability of the foreign tax credit carryforwards by considering
historical trends and future projections of U.S. taxable income, including temporary differences. Our historical U.S. GAAP income includes significant expenses that are not deductible for U.S. tax purposes, including the 2008 goodwill impairment
charge, which accelerates the use of the carryforwards on our tax returns. Utilization of the foreign tax credits is dependent upon future U.S. taxable income with the appropriate attributes. The U.S. income expectations were evaluated along with
the expiration dates of the carryforwards, and we concluded that recognition of the tax benefits was appropriate.

We have approximately $92.6
million ($25.9 million tax effect) of U.K. capital loss carryforwards that do not expire. The losses can only be used to offset future capital gains in the U.K. A full valuation allowance has been established on these deferred tax assets.

We also have other net deferred tax assets in the U.K. of approximately $125.1 million ($35.0 million tax effect), including ordinary tax
loss carryforwards of $52.8 million ($14.8 million tax effect) that do not expire. A full valuation allowance has been established on these deferred tax assets.

We have a net operating loss carryforward in Brazil of approximately $15.3 million ($5.2 million tax effect) that does not expire. A full valuation allowance has been established, as we do not foresee
future taxable income to utilize the carryforward in this entity.

We have net deferred tax assets in The Netherlands of approximately $76.1 million ($19.4 million tax
effect). This includes net operating loss carryforwards of approximately $55.0 million ($14.0 million tax effect) that will expire between 2013 and 2019 if not utilized. A valuation allowance has been established on $63.1 million ($16.1 million tax
effect) in part because of constraints on the utilization of the losses to shelter future income. In addition, projections of future income of the appropriate character are not sufficient to realize the benefits within a relevant period.

We have net deferred tax assets in France of $17.9 million ($6.1 million tax effect), including net operating losses that do not expire. A full valuation
allowance has been established on these deferred tax assets.

We have valuation allowances on certain other foreign net deferred tax assets,
including net operating loss carryforwards, with approximately $6.9 million tax effect.

The weighted-average interest rate on short-term debt was 2.80% and

2009 Refinancing

On May 13, 2009, Nalco Company, an indirect subsidiary of Nalco Holding Company, entered into new senior secured credit facilities (the New Senior
Secured Credit Facilities) consisting of a revolving credit facility expiring in May 2014 (the New Revolving Credit Facility) and a $750.0 million term loan facility expiring in May 2016 (the New Term Loan B). The
New Revolving Credit Facility provides for borrowings of up to $250.0 million and replaced the former $250.0 million revolving credit facility that would have otherwise expired on November 4, 2009. The U.S. dollar equivalent of $150.0 million
under

the New Revolving Credit Facility can be used, subject to certain collateral obligations, for borrowings by Nalco Company and certain non-U.S. subsidiaries in euros, pounds sterling and other
currencies to be agreed. The New Revolving Credit Facility also includes borrowing capacity available for letters of credit.

The terms of the
New Senior Secured Credit Facilities also allowed us to make future additional term loan borrowings of up to $250.0 million on terms to be agreed with future lenders. On November 25, 2009, we entered into Amendment No. 1 (the
Amendment) to the New Senior Secured Credit Facilities, which increased the amount of future additional term loan borrowings from $250.0 million to $550.0 million. The Amendment required that after giving effect to the incurrence of any
such additional term loans and the application of the proceeds of such term loans to redeem our 7.75% senior notes due 2011, no more than $200.0 million of the 7.75% senior notes due 2011 could remain outstanding. The Amendment also permitted us to
use up to $200.0 million of our cash to redeem our 7.75% senior notes due 2011 for a period of 180 days from the date of the Amendment, which was done.

On December 7, 2009, Nalco Company entered into a Joinder Agreement to the New Senior Secured Credit Facilities that provided for an additional $300.0 million term loan credit facility expiring in
May 2016 (the Term Loan C). We borrowed the full amount of Term Loan C on December 7, 2009, at a discount of $27.0 million, or 9.00%, of such new term loan.

Borrowings under the New Revolving Credit Facility, New Term Loan B and Term Loan C bear interest at a floating base rate plus an applicable margin. The applicable margin for borrowings under the New
Revolving Credit Facility ranges from 2.00% to 3.00% with respect to base rate borrowings and 3.00% to 4.00% with respect to LIBOR or Eurocurrency borrowings depending on our leverage ratio as defined by the revolving credit agreement. The initial
margin for the New Revolving Credit Facility is 2.50% with respect to base rate borrowings and 3.50% with respect to LIBOR or Eurocurrency borrowings. The applicable margin for borrowings under New Term Loan B is 2.50% with respect to base rate
borrowings and 3.50% with respect to LIBOR or Eurocurrency borrowings, with a base rate floor of 4.00% and a LIBOR or Eurocurrency floor of 3.00%. The applicable margin for borrowings under Term Loan C is 0.75% with respect to base rate borrowings
and 1.75% with respect to LIBOR or Eurocurrency borrowings.

Interest is generally due quarterly in arrears, and is also due upon expiration
of any particular loan. In addition, there is an annual loan commitment fee of 0.50% on the unused portion of the New Revolving Credit Facility. We are also required to pay a participation fee in respect of the undrawn portion of the letters of
credit, at a rate per annum equal to the applicable margin for LIBOR or Eurocurrency borrowings under the New Revolving Credit Facility, a fronting fee at a rate of 0.25% per annum of the daily average amount, as well as customary letter of
credit fees. As of December 31, 2009, we had $18.4 million in outstanding letters of credit, none of which had been drawn against.

New
Term Loan B and Term Loan C are subject to amortization at 1% of the initial principal amount per annum, payable quarterly. The remaining principal amount of New Term Loan B and Term Loan C is due on May 13, 2016.

The New Senior Secured Credit Facilities are unconditionally guaranteed by Nalco Company, Nalco Holdings LLC (the direct parent company of Nalco Company),
and certain domestic subsidiaries of Nalco Holdings LLC. The repayment of these facilities is secured by substantially all the assets of Nalco Company and the guarantors, including, but not limited to, a pledge of their capital stock and 65% of the
capital stock of each non-U.S. subsidiary owned by the guarantors.

At December 31, 2009, the weighted-average interest rate on borrowings under the New Senior Secured
Credit Facilities was 5.21%. Amounts outstanding, as well as the base rates and applicable margins, at December 31, 2009 were as follows:

Also on May 13, 2009,
Nalco Company issued $500.0 million aggregate principal amount of 8.25% senior unsecured notes (the Notes). The Notes were issued at a discount of $10.7 million. The Notes mature on May 15, 2017, with interest payable semi-annually
on May 15 and November 15 of each year. The Notes do not have required principal payments prior to maturity. Each of the direct and indirect subsidiaries of Nalco Holdings LLC and Nalco Company that guarantees its obligations under the New
Senior Secured Credit Facilities guarantees the Notes.

At its option, Nalco Company has the right to redeem some or all of the Notes
beginning May 15, 2013, at the redemption prices set forth below (expressed as a percentage principal amount), plus accrued interest, if any, if redeemed during the twelve-month period commencing on May 15 of the years set forth below:

Nalco Company also has the
right to redeem some or all of the Notes prior to May 15, 2013, at a price equal to the principal amount of the notes, plus a specified make-whole premium.

Net proceeds from New Term Loan B and the Notes were used to repay the remaining $15.0 million balance of the existing term loan A maturing on November 4, 2009, to repay $720.0 million of the
existing term loan B maturing on November 4, 2010, and to redeem $475.0 million aggregate principal amount of senior notes due November 2011. Available cash and net proceeds from Term Loan C were used to redeem 200.0 million
aggregate principal amount of senior notes due November 2011 and the remaining $190.0 million aggregate principal amount of senior notes due November 2011. We refer to these transactions, the issuance of the Notes, and our entry into the New
Revolving Credit Facility, New Term Loan B and Term Loan C, collectively, as the Refinancing.

As a result of the Refinancing, we
incurred a $20.5 million loss on extinguishment of debt, which is included in other income (expense), net. The loss was comprised of $10.4 million of accelerated amortization of deferred financing costs related to the existing term loans and senior
notes, a $9.2 million premium paid to redeem the $475.0 million of existing senior notes, and $0.9 million of other related charges.

In
connection with the Refinancing, we recorded deferred financing costs of $54.7 million related to the New Revolving Credit Facility, New Term Loan B, Term Loan C and the Notes, which will be amortized over their respective terms using the effective
interest method.

2003 Senior Secured Credit Facilities

On November 4, 2003, Nalco Company entered into senior secured credit facilities that included a $250.0 million revolving credit facility expiring in November 2009, a $200.0 million term loan A, a
88.0 million

term loan A, and a $1,300.0 million term loan B. Nalco Holdings LLC, Nalco Company, and certain domestic subsidiaries of Nalco Holdings LLC unconditionally guarantee the senior secured credit
facilities. The repayment of these facilities is secured by substantially all the assets of Nalco Company and the guarantors, including, but not limited to, a pledge of their capital stock and 65% of the capital stock of each non-U.S. subsidiary
owned by the guarantors.

As part of the Refinancing, the New Revolving Credit Facility replaced the $250.0 million revolving facility that
would have expired in November 2009, and we repaid the remaining $15.0 million balance of term loan A and $720.0 million of term loan B.

Borrowings under the term loan B facility bear interest at a floating base rate plus an applicable margin of 0.75% with respect to base rate borrowings and 1.75% with respect to LIBOR or Eurocurrency borrowings.

The weighted-average interest rate on borrowings under the 2003 senior secured credit facilities was 2.06% at December 31, 2009. Amounts outstanding,
as well as the base rates and applicable margins, at December 31, 2009 and December 31, 2008 were as follows:

Senior Notes, Senior
Subordinated Notes and Senior Discount Notes

On November 4, 2003, Nalco Company issued senior notes and senior subordinated notes.
The senior notes were issued in the principal amount of $665.0 million and 200.0 million and an interest rate of 7.75%. The senior subordinated notes were issued in the principal amount of $465.0 million and 200.0 million and
interest rates of 8.875% and 9.00%, respectively. Interest is payable semi-annually on May 15 and November 15. The notes do not have required principal payments prior to maturity. The indirect subsidiaries of Nalco Holding Company and the
direct and indirect subsidiaries of Nalco Company that guarantee Nalco Companys obligations under the New Senior Secured Credit Facilities and the senior secured credit facilities guarantee the notes.

As part of the Refinancing, Nalco Company redeemed the $665.0 million and 200.0 million senior notes due 2011.

At its option, Nalco Company has the right to redeem some or all of the senior subordinated notes, beginning November 15, 2009, at the redemption
prices set forth below (expressed as percentages of principal amount), plus accrued interest, if any, if redeemed during the twelve-month period commencing on November 15 of the years set forth below:

In January 2004, Nalco Holding
Companys 100%-owned subsidiaries, Nalco Finance Holdings LLC and Nalco Finance Holdings Inc. (together, the Issuers), issued $694.0 million aggregate principal amount at maturity of 9.00% senior discount notes due 2014. In December
2004, the Issuers redeemed a portion of the senior discount notes using proceeds from the initial public offering of common stock of Nalco Holding Company.

11.    Debt (continued)



After the partial redemption, the aggregate principal amount at maturity of the notes declined to $460.8
million. Prior to February 1, 2009, interest accrued on the notes in the form of an increase in the accreted value of such notes. The accreted value of each note increased from the date of issuance until February 1, 2009, at a rate of
9.00% per annum, reflecting the accrual of non-cash interest, such that the accreted value equaled the principal amount at maturity of $460.8 million. Cash interest payments on the notes became due and payable beginning in August 2009.

Nalco Holding Company and the Issuers do not generate any revenue, and Nalco Finance Holdings Inc. was incorporated solely to accommodate the
issuance of the senior discount notes by Nalco Finance Holdings LLC. All of Nalco Holding Companys consolidated assets are owned, and all of its consolidated net sales are earned, by its direct and indirect subsidiaries. As of
December 31, 2009, Nalco Holding Companys subsidiaries had $603.8 million of restricted net assets.

The terms of the New Senior
Secured Credit Facilities and the 2003 senior credit facilities of Nalco Company limit the amount of dividends and other transfers by Nalco Holdings LLC and its subsidiaries to the Issuers or Nalco Holding Company. Further, the terms of the
indentures governing the Notes and senior subordinated notes of Nalco Company significantly restrict Nalco Company and the Issuers other subsidiaries from paying dividends or otherwise transferring assets to the Issuers or Nalco Holding
Company. The ability of Nalco Company to make such payments is governed by a formula based on its consolidated net income, as well as meeting certain other conditions. Notwithstanding such restrictions, such indentures permit an aggregate of $50.0
million of such payments to be made whether or not there is availability under the formula or the conditions to its use are met.

Covenants

The New Senior Secured Credit Facilities, the 2003 senior secured credit facilities, the Notes, the senior discount notes, and the senior
subordinated notes contain a number of covenants that, among other things, restrict, subject to certain exceptions, our ability to sell assets; incur additional indebtedness or issue preferred stock; repay other indebtedness; pay dividends and
distributions or repurchase certain capital stock; create liens on assets; make investments, loans or advances; make acquisitions, mergers or consolidations; enter into sale and leaseback transactions; engage in certain transactions with affiliates;
amend certain material agreements governing our indebtedness; change our business; and enter into hedging agreements. In addition, we must maintain financial covenants, including a maximum total leverage ratio, a minimum interest coverage ratio, and
a maximum capital expenditure limitation. The New Senior Secured Credit Facilities and the Notes also include a maximum total leverage ratio. We were in compliance with all covenants at December 31, 2009.

The following table presents the projected annual maturities of long-term debt for years after 2009:



|                        |  |   |        
|----------------------- |  | - | -------
|Year ending December 31 |  |   |        
|2010                    |  | $ | 177.5  
|2011                    |  |   | 10.6   
|2012                    |  |   | 10.6   
|2013                    |  |   | 763.3  
|2014                    |  |   | 471.5  
|Thereafter              |  |   | 1,493.7
|                        |  |   |        
|                        |  | $ | 2,927.2
|                        |  |   |        

The $35.4 million difference between the total projected annual
maturities of long-term debt of $2,927.2 million and the carrying value of $2,891.8 million is mostly attributable to the $26.7 million discount on Term Loan C and the $9.8 million discount on the Notes. Partly offsetting that difference is the $1.1
million unamortized premium attributable to the senior discount notes.

12.    Leases

We lease administrative, research, manufacturing, and warehouse facilities and data processing and other equipment under non-cancelable leases that expire at various dates through 2027. Rent expense
totaled $44.4 million, $43.1 million and $39.4 million for the years ended December 31, 2009, 2008 and 2007, respectively.

Future
minimum rental payments for operating leases related to facilities, with initial or remaining terms greater than one year, are as follows:



|                        |  |   |      
|----------------------- |  | - | -----
|Year ending December 31 |  |   |      
|2010                    |  | $ | 35.2 
|2011                    |  |   | 47.0 
|2012                    |  |   | 21.2 
|2013                    |  |   | 17.3 
|2014                    |  |   | 15.6 
|Thereafter              |  |   | 143.6
|                        |  |   |      
|                        |  | $ | 279.9
|                        |  |   |      

The amounts in the table above include future minimum rental payments
for our corporate headquarters and research facility of $17.1 million in 2010, $35.1 million in 2011, $12.7 million in 2012, $12.7 million in 2013, $12.7 million in 2014, and $112.0 million from 2015 through 2023.

13.    Sale-Leaseback Transaction

In December 2002, the Predecessor entered into an agreement whereby it sold and leased back its corporate headquarters and research facility in Naperville, IL. As a result of the sale, the Predecessor
received proceeds of $144.8 million, net of $5.2 million of transaction costs. The related lease was for an initial term of 25 years, and required the Predecessor to make total minimum payments of $264.2 million over the initial lease term. The
lease agreement provided for two fixed rate renewal periods of 5 years each and two fair value renewal periods of 5 years each.

The
Predecessors payment obligations, along with certain other items under the lease agreement, were fully guaranteed by Suez. Because of the guarantee, the Predecessor was precluded from accounting for this transaction as a sale and leaseback of
the property and instead accounted for it as a financing, with an effective interest rate of 5.5%. The Predecessor provided a cross guarantee to Suez of any payments made by Suez under its guarantee.

Under the terms of an agreement executed November 4, 2003 between Leo Holding Company (Leo), a subsidiary of Suez, and us, we assigned our rights and
obligations under the lease agreement to Leo. Simultaneously, Suez was released from its guarantee, and we entered into an agreement with Leo whereby we sublease our corporate headquarters and research facility from Leo. The terms of the sublease
agreement are generally identical to those of the lease agreement that was assigned to Leo. As a result of these transactions, the leased property, the remaining obligation under the lease assigned to Leo, and the related deferred income taxes were
removed from our balance sheet as part of the allocation of the Acquisition purchase price. We account for the sublease as an operating lease.

On November 4, 2003, we entered into a Reimbursement Agreement with Suez whereby Suez shall reimburse us for all contributions we make to the Profit Sharing, Investment and Pay Deferral Plan Trust (see Note 8). All remaining
contributions for which Suez will be required to reimburse us will be made in 2010. Under the terms of the sublease agreement, if Suez fails to pay any of the payments required to be made under the Reimbursement Agreement, we shall have the right to
set off such overdue amounts against the rent due under the sublease agreement.

14.    Pension and Other Postretirement Benefit Plans

We have several noncontributory, defined benefit pension plans covering most employees in the U.S. and those with certain foreign subsidiaries. We also
provide a supplementary, nonqualified, unfunded plan for U.S. employees whose pension benefits exceed ERISA limitations. In addition, we have defined benefit postretirement plans that provide medical, dental, and life insurance benefits for
substantially all U.S. retirees and eligible dependents. We retain the right to change or terminate these benefits.

At the end of 2002, the
domestic pension plan was amended such that beginning January 2003, pension benefits no longer accrue for those participants in the pension plan hired or rehired after October 1999 and for those participants hired before November 1999, but with less
than five years of vesting service at the end of 2002. However, these participants continued to earn vesting service. For those participants hired before November 1999 and with more than five years of vesting service, the pension plan was amended to
reduce future benefit accruals and to increase the reduction factors for early retirement.

Also during 2002, eligibility for participation in
the defined benefit postretirement medical and dental plans was changed from age 55 with at least ten years of service to age 55 with at least ten years of service after age 45. Also, employees with less than five years of service at the end of 2003
will only be provided access to coverage at retirement; we will not contribute to the cost of the coverage. The plans were also amended such that retirees and their dependents are required to pay 50% of plan costs in 2005 and beyond.

In 2009, the domestic pension plan was amended such that effective January 1, 2010, participants will no longer earn service credit. The defined
benefit pension plan in the U.K. was similarly amended. The net periodic pension cost for those plans will no longer have a service component.

The following tables detail the changes in the funded status of defined benefit pension and other postretirement benefit plans:

14.    Pension and Other Postretirement Benefit Plans (continued)



The principal U.S. defined benefit pension plan provides terminating participants with an option to
receive their pension benefits in the form of lump sum payments. Authoritative guidance for pension accounting requires settlement accounting if lump sum payments exceed the sum of the service and interest cost components of net periodic pension
cost of the plan for the fiscal year. During 2009, a number of terminating participants received lump sum benefit payments, and the settlement accounting requirement was triggered, resulting in a $21.4 million settlement loss attributable to the
principal U.S. pension plan in 2009.

Net other postretirement benefit expense was comprised of:

pension plans were as follows:

The assets in the principal
domestic pension plan are invested to obtain a reasonable long-term rate of return at an acceptable level of investment risk. Risk tolerance is established through careful consideration of plan liabilities, plan funded status, and corporate
financial condition. Investment risk is measured and monitored on an ongoing basis through periodic investment portfolio reviews, liability measurements and asset/liability studies. A similar approach to assessing investment risk and obtaining
reasonable investment returns is employed for the foreign pension plans.

The assets in the principal domestic pension plan are diversified
across equity, fixed income and alternative investments such as hedge funds and private equity. The investment portfolio has target allocations of approximately 49% equity, 32% fixed income and 19% alternative investments. Other assets such as real
estate may be used judiciously to enhance portfolio returns and diversification. The foreign pension plans have comparable asset allocation to the principal domestic plan, with some variances for local practices.

The expected long-term rate of return is established using historical market data for each asset class as well as the target allocation. Historical markets
are analyzed and long-term historical relationships between equity and fixed income investments are preserved consistent with the widely accepted capital market principle that assets with higher volatility will generate a greater return over the
long run. Active management is employed in most asset classes, which also contributes to the return assumption. The total weighted-average return on each asset class supports the long-term expected rate of return assumption.

15.    Equity
Compensation Plans

The Nalco Holding Company 2004 Stock Incentive Plan (the Plan) was adopted to aid us in recruiting and
retaining key employees, directors and consultants and to motivate them to exert their best efforts on our behalf. The Plan, which permits the grant of stock options, stock appreciation rights, restricted stock and other stock-based awards for up to
7.5 million shares of common stock, is administered by the Compensation Committee of the Board of Directors. The Compensation Committee may delegate its duties and powers in whole or in part as it determines.

In connection with his employment as our President and Chief Executive Officer in 2008, J. Erik Fyrwald was granted 200,000 shares of restricted stock and
190,000 stock options outside the Plan. Of the restricted stock awards, 100,000 shares vest on each of the third and fourth anniversaries after the grant date. Of the stock option awards, which have a contractual term of ten years, 75,000 options
vest on each of the third and fourth anniversaries after the grant date. The remaining 40,000 options vest ratably beginning on December 31, 2008, and on December 31 of the following three years.

Stock option awards granted under the Plan have a contractual term of ten years, and usually vest ratably over four years after the grant date. The exercise
price of option awards is equal to the market price of Nalco Holding Company common stock on the date granted.

The fair value of option awards was estimated using the Black-Scholes option-pricing model and the
following assumptions:



|                        |  |       |   |  |                |  |      |  
|----------------------- |  | ----- | - |  | -------------- |  | ---- | -
|                        |  | 2009  |   |  | 2008           |  | 2007 |  
|Expected life (years)   |  | 6.25  |   |  | 6.125  6.75   |  | 6.25 |  
|Risk-free interest rate |  | 2.55  | % |  | 2.83%  3.42%  |  | 4.69 | %
|Expected volatility     |  | 58.68 | % |  | 38.34% 55.63% |  | 25.5 | %
|Expected dividend yield |  | 1.17  | % |  | 0.61%  0.98%  |  | 0.58 | %

Because Nalco Holding Company
has been a public company only since November 2004, there is limited historical data on the volatility of its common stock. As a result, the expected volatility of the option awards was estimated using an implied volatility from traded options on
Nalco Holding Company common stock. Since historical information concerning option exercise behavior by our employees is very limited and such information is not readily available from a peer group of companies, the expected life was estimated using
the simplified method permitted by Staff Accounting Bulletin Nos. 107 and 110 issued by the SEC.

The following table summarizes
the status of option awards as of December 31, 2009, and changes during the year then ended:

The weighted-average grant-date fair value of options granted during
2009, 2008 and 2007 was $6.16, $8.20 and $8.15, respectively.

Restricted stock awards are granted to non-management directors and certain key
employees. Awards granted to non-management directors vest approximately two years after the grant date. Awards granted to key employees vest over periods ranging from approximately one to five years following the grant date. The fair value of
restricted stock awards is determined based on the market price of Nalco Holding Company common stock on the date of grant. The weighted-average grant-date fair value of restricted stock awards granted during 2009, 2008 and 2007 was $12.49, $21.15
and $25.53, respectively.

15.    Equity Compensation Plans (continued)



We recognize compensation expense related to option and restricted stock awards on a straight-line basis
over the vesting periods. As of December 31, 2009, there was $12.5 million of total unrecognized compensation cost related to nonvested option and restricted stock awards. We expect to recognize that cost over a weighted-average period of 2.1
years. The fair value of restricted stock awards that vested during 2009, 2008 and 2007 was $0.4 million, $0.9 million and $0.9 million, respectively. The total intrinsic value of options exercised during 2009 and 2008 was $0.5 million in each year.
Cash received from the exercise of stock options was $0.6 million and $0.4 million in 2009 and 2008, respectively. No option awards were exercised in 2007.

Performance share awards provide for the issuance of common stock to certain key employees if specified performance targets are achieved. For most performance share awards, the number of common shares
that will be issued is dependent upon vesting and actual performance of the Company relative to certain financial targets approved by our Board of Directors, and could range from 0% to 150% of the performance shares granted. For certain performance
share awards, the number of shares that will be issued could range from 0% to 200% of the performance shares granted. The performance shares vest approximately three years following the grant date. The fair value of performance share grants is
determined based on the market price of Nalco Holding Company common stock on the date of grant, and the amount of compensation expense recognized reflects estimated forfeiture rates and managements assessment of the probability that
performance goals will be achieved. We recognize compensation expense related to performance share grants ratably over the vesting periods.

The following table summarizes the status of performance share awards as of December 31, 2009, and changes during the year then ended:

There was $6.9 million of total unrecognized compensation cost related to performance share awards as of
December 31, 2009, which we expect to recognize over a weighted-average period of 1.9 years. The fair value of performance share awards that vested during 2009, 2008 and 2007 was $2.1 million, $1.0 million and $1.1 million, respectively.

During 2004, Nalco LLC, wholly owned by the Sponsors and our direct parent company at the time, established the Nalco LLC 2004 Unit Plan (the
Unit Plan) for purposes of (i) attracting and retaining exceptional officers and other key employees, non-employee directors and consultants and (ii) enabling such individuals to acquire an equity interest in Nalco LLC and to
participate in its and our long-term growth and financial success.

During 2004, Nalco LLC granted certain of our officers and key employees
rights to purchase a designated number of one or more classes of equity interests (Units) in Nalco LLC. Those officers and key employees who elected to purchase such Units did so at the Units fair value, discounted for any vesting
provisions, as determined by a valuation consultant, since Nalco LLC is a private company and there is no public market for its shares.

The
Units subject to the Unit Plan included class A, class B, class C, and class D Units. The class A Units were fully vested at the time of purchase by an employee and have economic characteristics that are similar to those of shares of common stock in
a private corporation. The class B, class C, and class D Units were subject to vesting provisions, meaning that in order for such Units to be entitled to

distributions or other benefits, an employee would have to continue to provide services for a certain period of time. The Unit Plan was modified in 2006 to reduce the vesting period for class C
and class D Units and to eliminate provisions that accelerated the vesting of those Units if specified EBITDA performance targets were achieved. The modifications did not result in incremental compensation expense.

Though Nalco LLC established the Unit Plan, we account for the Unit Plan since its economic substance is substantially the same for our employees and us.
There has been no unrecognized compensation cost related to the Unit Plan since December 31, 2008.

Compensation cost charged to earnings
for all equity compensation plans discussed above was $11.1 million, $5.9 million and $3.5 million for 2009, 2008 and 2007, respectively. The total income tax benefit recognized in the consolidated statement of operations was $4.2 million, $2.2
million and $1.3 million for 2009, 2008 and 2007, respectively.

We also recognized non-cash charges to earnings of $0.6 million during 2008
that resulted from modifying the terms of some Unit Plan awards for certain exiting employees. Most of these charges have been reported as part of restructuring expenses in the consolidated statement of operations. Due to the tax attributes of the
Unit Plan, no tax benefit was recognized for the expense that resulted from modifying the terms of the awards.

In November 2007, it was
announced that Dr. William H. Joyce, our Chairman and Chief Executive Officer, had stated his intention to retire on December 30, 2007. At the same time, it was also announced that we had entered into an amended Employment and
Consulting Agreement with Dr. Joyce concerning his remaining service as CEO through the remainder of 2007, his consulting services through March 2008, and certain compensation matters. As part of the agreement, Dr. Joyce received a grant
of nonvested common stock valued at $12.0 million. Vesting of the stock is subject to certain performance and other conditions. During 2008, 349,677 shares vested at a fair value of $5.6 million. No vesting occurred in 2009.

Because Dr. Joyce was not required to provide substantive services to us subsequent to 2007 and vesting of the stock was considered probable at the
time, we charged the entire $12.0 million of compensation expense to earnings and recognized an income tax benefit of $4.6 million in 2007. Also, because the grant included a provision requiring cash settlement in the event of the death of
Dr. Joyce, the $12.0 million was classified with other liabilities in the balance sheet until such time that cash settlement was no longer possible. We reclassified $8.0 million from other liabilities to additional paid-in capital during 2008
for that portion of the grant no longer subject to cash settlement. During 2009, $4.0 million of compensation cost related to 2009 performance was reversed once it was determined that targeted performance criteria would not be achieved. At
December 31, 2009, there is no unrecognized compensation cost associated with this grant.

In November 2004, a warrant to purchase, for $0.01 per share, up to 6,191,854 shares of Nalco Holding Company common stock
was issued as part of a dividend to Nalco LLC, our sole stockholder on the record date of the dividend. The warrant enabled Nalco LLC to deliver shares to members of our management who had the right to put, or sell, their vested class B, class C and
class D Units to Nalco LLC. Subject to limited exceptions, the warrant became exercisable upon the occurrence of the same specified events applicable to the vesting of the Nalco LLC class B Units, class C Units and class D Units (except that there
was no service requirement comparable to that applicable to the individual holders of the class B, class C and class D Units). At December 31, 2008, Nalco LLC could repurchase up to 1,414,399 shares of Nalco Holding Company common stock under
the warrant. Nalco LLC exercised warrants to acquire 625,299 shares of common stock during the year ended December 31, 2009, and agreed to terminate and waive all of its remaining rights under the warrant. Accordingly, the warrant for the
remaining 789,100 shares was cancelled. Nalco LLC exercised warrants to acquire 2,126,650 and 1,265,806 shares of Nalco Holding Company common stock during 2008 and 2007, respectively.

On July 31, 2007, our Board of Directors authorized a $300 million share repurchase program, and gave our management discretion in determining the conditions under which shares may be purchased from
time to time. The program has no stated expiration date. We repurchased 4,947,443 shares at a cost of $103.3 million during 2008 and 4,588,500 shares at a cost of $108.0 million during 2007.

17.    Financial Instruments

We use derivative instruments to manage our foreign exchange and energy cost exposures. All derivative instruments are recognized in the consolidated balance sheets at fair value. Changes in the fair value of derivatives that are not
designated as hedges are recognized in earnings as they occur. If the derivative instruments are designated as hedges, depending on their nature, the effective portions of changes in their fair values are either offset in earnings against the
changes in the fair values of the items being hedged, or reflected initially as a separate component of equity and subsequently recognized in earnings when the hedged items are recognized in earnings. The ineffective portions of changes in the fair
values of derivative instruments designated as hedges are immediately recognized in earnings.

Counterparties to derivative financial instruments expose us to credit-related losses in the event of
nonperformance, but we do not expect any counterparties to fail to meet their obligations given their high credit ratings.

Net Investment
Hedges

We have used euro-denominated senior notes, senior subordinated notes and term loan borrowings as a hedge of our net investment in
subsidiary companies whose assets, liabilities, and operations are measured using the euro as their functional currency. Because of the high degree of effectiveness between the hedging instruments and the exposure being hedged, fluctuations in the
value of the euro-denominated debt due to exchange rate changes are offset by changes in the net investment. Accordingly, changes in the value of the euro-denominated debt are recognized in foreign currency translation adjustment, a component of
accumulated other comprehensive income, to offset changes in the value of our net investment in subsidiary companies whose financial statements are measured using the euro as their functional currency.

The carrying value of euro-denominated debt designated as a net investment hedge was $287.7 million at December 31, 2009. Gains and losses from the net
investment hedge reported as a component of other comprehensive income in the foreign currency translation adjustment account were as follows:

We formally assess, on a quarterly basis, whether the euro-denominated debt is effective at offsetting changes in the value
of the underlying exposure. No hedge ineffectiveness was recorded in earnings during 2009, 2008 and 2007.

Cash Flow Hedges

We use derivative instruments such as foreign exchange forward contracts to hedge the variability of the cash flows from certain forecasted royalty
payments due to changes in foreign exchange rates, and we use commodity forward contracts to manage our exposure to fluctuations in the cost of natural gas used in our business. These instruments are designated as cash flow hedges, with changes in
their fair values included in other comprehensive income to the extent the hedges are effective. Amounts included in accumulated other comprehensive income are reclassified into earnings in the same period during which the hedged transaction is
recognized in earnings. Changes in fair value representing hedge ineffectiveness are recognized in current earnings. No derivative instruments were designated as cash flow hedges at December 31, 2009, and no cash flow hedges were discontinued
during 2009, 2008 and 2007.

Fair Value Hedges

For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item attributable to the hedged
risk, are recognized in current earnings. No derivative instruments were designated as a fair value hedge at December 31, 2009.

Derivatives Not Designated as Hedging Instruments

We use foreign currency contracts to offset the impact of exchange rate
changes on recognized assets and liabilities denominated in non-functional currencies, including intercompany receivables and payables.

18.    Fair Value of Financial Instruments

Authoritative guidance issued by the FASB defines fair value as the price that would be received for an asset or paid to transfer a liability in an orderly
transaction between market participants on the measurement date. The guidance establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels:

Level 1  Quoted prices in active markets that are accessible at the measurement date for identical assets and liabilities. The fair
value hierarchy gives the highest priority to Level 1 inputs.

Level 2  Observable inputs other than quoted prices in
active markets.

Level 3  Unobservable inputs for which there is little or no market data available. The fair value
hierarchy gives the lowest priority to Level 3 inputs.

The fair value of financial assets and liabilities measured at fair value on a
recurring basis was as follows:

Foreign exchange forward contracts are valued using quoted forward
foreign exchange prices at the reporting date. Natural gas forward contracts are valued using NYMEX futures prices for natural gas at the reporting date.

The carrying values of cash and cash equivalents, trade accounts receivable, accounts payable and short-term debt approximate their fair values at December 31, 2009 and 2008, because of the
short-term maturities and nature of these balances.

The estimated fair value of long-term debt at December 31, 2009 and 2008 was
$2,769.7 million and $2,773.9 million, respectively, and the related carrying value was $2,714.3 million and $3,129.6 million, respectively. The fair value of our senior notes, senior subordinated notes and senior discount notes was estimated based
on their quoted market prices. The carrying value of amounts outstanding under our senior secured credit facilities is considered to approximate fair value because interest accrues at rates that fluctuate with interest rate trends. The carrying
value of other long-term debt outstanding also approximates fair value due to the variable nature of their interest rates.

19.    Restructuring Expenses

We continuously redesign and optimize our business and work processes, and
restructure our organization accordingly. During the year ended December 31, 2009, plans were approved to set a lower cost base through restructuring actions, primarily in Europe. As a result, we recognized $47.8 million of restructuring costs
in 2009, which included $27.1 million in charges for employee severance and related

costs, reflecting a reduction in force of more than 300 positions. In addition, certain long-lived assets held and used were written down to their estimated fair value, resulting in an impairment
loss of $20.2 million. The fair value of the assets was measured using a combination of market participant inputs and internal cash flow estimates (i.e., Level 3 in the fair value hierarchy established by authoritative guidance issued by the FASB
for fair value measurements). We also recognized $0.5 million of losses on assets disposed of as part of our restructuring activities.

Restructuring expenses, representing mostly employee severance and related costs, were $33.4 million and $15.3 million for the years ended December 31, 2008 and 2007, respectively. The increase in restructuring expenses in 2008 was
mainly the result of a reduction in force of more than 400 positions as part of an organizational realignment.

Restructuring accruals of
$29.5 million and $28.2 million as of December 31, 2009 and 2008, respectively, were included in other current liabilities on the consolidated balance sheet. All restructuring-related payments in 2009, 2008 and 2007 were funded with cash from
operations, and we expect that future payments also will be funded with cash from operations. The following table summarizes the activity for the restructuring charges discussed above and the related accrual:

21.    Earnings Per Share

Basic earnings per share is computed by dividing net earnings attributable to Nalco Holding Company common shareholders by the weighted-average number of
common shares outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance
of common stock.

Basic and diluted earnings per share were calculated as follows:

There were 0.5 million shares, 2.4 million shares and
0.1 million shares potentially issuable under share-based compensation plans at December 31, 2009, 2008 and 2007, respectively, that were excluded from our diluted earnings per share computation, as the effect of including such shares
would be anti-dilutive.

22.    Segment Information

We provide integrated water treatment and process improvement services for industrial and institutional applications, using technologically advanced solutions, combining chemical products and equipment,
and consistent, reliable on-site service and expertise.

These solutions and services enable our customers to improve production yields, lower
manufacturing costs, extend asset lives and maintain environmental standards at costs that represent a small share of their overall production expense.

We operate three reportable segments:

Water Services  This segment serves the
global water treatment and process chemical needs of the industrial, institutional, and municipal markets.

Paper Services This segment serves the process chemicals and water treatment needs of the global pulp and paper industry.

Energy
Services This segment serves the process chemicals and water treatment needs of the global petroleum and petrochemical industries in both upstream and downstream applications.

In 2009, our Industrial and Institutional Services segment was renamed Water Services. We also began reporting Other segment results related to the Water
Services, Paper Services and Energy Services segments with those segments. This former segment included an Integrated Channels group, supply chain activities, standard cost variances, and certain other operating expenses. In addition, we
discontinued the assessment of an internal non-GAAP capital charge to each segment. Amounts for prior periods have been restated to conform with these changes.

We evaluate the performance of our segments based on direct contribution, which is defined
as net sales, less cost of products sold, selling and service expenses, marketing expenses, and research expenses directly attributable to each segment. There are no intersegment revenues.

Administrative expenses primarily represent the cost of support functions, including information technology, finance, human
resources and legal, as well as expenses for support facilities, executive management and management incentive plans.

We have a single supply
chain function that serves all the reportable segments. As such, asset and capital expenditure information by reportable segment has not been reported and is not available, since we do not produce such information internally. In addition, although
depreciation expense is a component of each reportable segments direct contribution, it is not discretely identifiable.

Net sales by geographic area were determined based on origin of sale.
Geographic data on long-lived assets is based on physical location of those assets. There were no sales from a single foreign country or customer that were material to our consolidated net sales.

23.    Contingencies and Litigation

Various claims, lawsuits and administrative proceedings are pending or threatened against us, arising from the ordinary course of business with respect to commercial, contract, intellectual property,
product liability, employee, environmental and other matters. Historically, these matters have not had a material impact on our consolidated financial position. However, we cannot predict the outcome of any litigation or the potential for future
litigation.

We have been named as a potentially responsible party (PRP) by the Environmental Protection Agency or state enforcement agencies
at seven waste sites where some financial contribution is or may be required. These agencies have also identified many other parties who may be responsible for clean up costs at these waste disposal sites. We are also remediating a small ground
contamination that we discovered at our plant in Pilar, Argentina. Our financial contribution to remediate these sites is not expected to be material. There has been no significant financial impact on us up to the present, nor is it anticipated that
there will be in the future, as a result of these matters. We have made and will continue to make provisions for these costs if our liability becomes probable and when costs can be reasonably estimated.

Our undiscounted reserves for known environmental clean up costs were $2.2 million at December 31, 2009. These environmental reserves represent our
current estimate of our proportional clean-up costs and are based upon negotiation and agreement with enforcement agencies, our previous experience with respect to clean-up activities, a detailed review by us of known conditions, and information
about other PRPs. They are not reduced by any possible recoveries from insurance companies or other PRPs not specifically identified. Although we cannot determine whether or not a material effect on future operations is reasonably likely to occur,
given the evolving nature of environmental regulations, we believe that the recorded reserve levels are appropriate estimates of the potential liability. Although settlement will require future cash outlays, it is not expected that such outlays will
materially impact our liquidity position.

defective or hazardous materials and the claimed presence of hazardous substances at our plants. We have also been named as a defendant in lawsuits where our products have not caused injuries, but the claimants seek amounts so they might be
monitored in the future for potential injuries arising from our products. The plaintiffs in these cases seek damages for alleged personal injury or potential injury resulting from exposure to our products or other chemicals. These matters have had a
de minimis impact on our business historically, and we do not anticipate these matters will present any material risk to our business in the future. Notwithstanding, we cannot predict the outcome of any such lawsuits or the involvement we
might have in these matters in the future.

In the ordinary course of our business, we are also a party to a number of lawsuits and are
subject to various claims relating to trademarks, employee matters, contracts, customer claims, negligence, transactions, chemicals and other matters, the outcome of which, in our opinion, should not have a material effect on our consolidated
financial position.

However, we cannot predict the outcome of any litigation or the potential for future litigation. Were an unfavorable
ruling to occur, there exists the possibility of a material adverse impact on the results of operations for the period in which the ruling occurs. We maintain accruals where the outcome of the matter is probable and can be reasonably estimated.

25.    Subsequent Event

Effective January 1, 2010, Venezuelas economy is considered to be highly inflationary under U.S. generally accepted accounting principles, since it has experienced a rate of general inflation in excess of 100% over the last
three-year period. Accordingly, all gains and losses resulting from the remeasurement of our financial statements are required to be recorded directly in the statement of operations. On January 8, 2010, the Venezuelan government announced the
devaluation of the bolivar fuerte and the establishment of a two-tier exchange structure of 4.30 per U.S. dollar for non-essential items and 2.60 per U.S. dollar for food, medical supplies and other national priorities.

As a result, we expect to record a charge in the first quarter of 2010 in connection with the remeasurement of our balance sheet accounts to reflect the
devaluation. If calculated at the exchange rate for non-essential items of 4.30 bolivares fuertes per U.S. dollar, the exchange loss is expected to be approximately $21 million. To the extent that our imports are classified as essential, this impact
could be reduced.

Note to Condensed Financial Statements

December 31, 2009

1.    Basis of Presentation

Under the terms of agreements governing indebtedness of certain subsidiaries of Nalco Holding Company (the Company), such subsidiaries are significantly restricted from making dividend
payments, loans or advances to the Company. These restrictions have resulted in the restricted net assets (as defined in Rule 4-08(e)(3) of Regulation S-X) of the Companys subsidiaries exceeding 25% of the consolidated net assets of the
Company and its subsidiaries.

The financial statements for Nalco Holding Company (Parent Company Only) summarize the results of operations
and cash flows for the years ended December 31, 2009, 2008 and 2007, and the financial position as of December 31, 2009 and 2008. In these statements, the Companys investment in subsidiaries is stated at cost plus equity in
undistributed earnings of subsidiaries since the date of acquisition, November 4, 2003. The Companys share of net income of its unconsolidated subsidiaries is included in consolidated income using the equity method. The Nalco Holding
Company parent-company-only financial statements should be read in conjunction with the consolidated financial statements of Nalco Holding Company and subsidiaries.
