PART I

ITEM 1. BUSINESS

General

Please note that, unless otherwise indicated or the context
requires otherwise, when we use the terms we, the Company, our or us, we mean Koppers Inc., formerly known as Koppers Industries, Inc., and its subsidiaries on a consolidated basis.

We are a leading integrated global provider of carbon compounds and commercial wood treatment products. Our products are used in a variety of niche applications in a diverse range
of end-markets, including the aluminum, railroad, specialty chemical, utility, rubber and steel industries. We serve our customers through a comprehensive global manufacturing and distribution network, with manufacturing facilities located in the
United States, Australia, China, the United Kingdom and Denmark. For the twelve months ended December 31, 2008, we had net sales of $1,364.8 million and net income of $150.9 million.

We operate two principal businesses: Carbon Materials & Chemicals and Railroad & Utility Products. Through our Carbon Materials & Chemicals business (65 percent of 2008 net sales), we believe we are
the largest distiller of coal tar in North

America, Australia, the United Kingdom and Scandinavia. We process coal tar into a variety of products, including carbon pitch,
creosote and phthalic anhydride, which are critical intermediate materials in the production of aluminum, the pressure treatment of wood and the production of plasticizers and specialty chemicals, respectively. Through our Railroad &
Utility Products business (35 percent of 2008 net sales), we are the largest North American supplier of railroad crossties. Our other commercial wood treatment products include utility poles for the electric and telephone utility industries.

We were formed in October 1988 as Koppers Industries, Inc. under the laws of the Commonwealth of Pennsylvania by management, Beazer, Inc. and KAP
Investments, Inc. (KAP, a subsidiary of Koppers Australia Pty. Limited) (Koppers Australia) to facilitate the acquisition of certain assets of Koppers Company, Inc. in a management-led leveraged buyout that closed on
December 29, 1988 (the Acquisition). Koppers Company, Inc., now known as Beazer East, Inc. (Beazer East had been acquired in June 1988 by BNS Acquisitions, Inc., a wholly owned indirect subsidiary of Beazer PLC, now
known as Beazer Limited (Beazer Limited).

Subsidiary of Koppers Holdings Inc.

On November 12, 2004, Koppers Holdings Inc. (Koppers Holdings, formerly KI Holdings) was incorporated. On
November 18, 2004, all of our common and preferred stock was converted into shares of common and preferred stock of Koppers Holdings and Koppers Holdings issued and sold $203.0 million aggregate principal amount at maturity ($125.5 million
gross proceeds) 97/8 percent Senior Discount Notes due 2014 (the Senior
Discount Notes). The Senior Discount Notes are not a direct obligation of Koppers Inc. Koppers Holdings has no direct operations and no significant assets other than our stock. It depends on dividends from the earnings of us and our
subsidiaries to generate the funds necessary to meet its financial obligations, including payments of principal, interest, and other amounts on the Senior Discount Notes. The terms of our revolving credit facility prohibit us from paying dividends
and otherwise transferring assets except for certain limited dividends. Further, the terms of the indenture governing our Senior Secured Notes (as described herein) significantly restrict us from paying dividends and otherwise transferring assets to
Koppers Holdings.

Industry Overview

Carbon Materials & Chemicals

Our Carbon Materials & Chemicals business manufactures five principal products: (a) carbon pitch, used in the production of aluminum and steel;
(b) phthalic anhydride, used in the production of plasticizers and polyester resins; (c) creosote and carbon black feedstock, used in the treatment of wood or as a feedstock in the production of carbon black; (d) carbon black, used in
the manufacture of rubber tires; and (e) naphthalene, used primarily as a surfactant in the production of concrete. Carbon pitch, phthalic anhydride, creosote (and carbon black feedstock) and naphthalene are produced through the distillation of
coal tar. Coal tar is a by-product generated through the processing of coal into coke for use in steel and iron manufacturing. We produce and distribute a variety of intermediate chemical products derived from the coal tar distillation process,
including the co-products of the distillation process. During the distillation process, heat and vacuum are utilized to separate coal tar into three primary components: carbon pitch (approximately 50 percent), creosote oils (approximately 30
percent) and chemical oils (approximately 20 percent). Because all coal tar products are produced in relatively fixed proportion to carbon pitch, the level of carbon pitch consumption generally determines the level of production of other coal tar
products.

Koppers Inc.2008 Annual Report



The Carbon Materials & Chemicals business profitability is impacted by the cost of purchasing coal tar in relation to its prices realized for carbon pitch, phthalic anhydride, creosote, and naphthalene. We have
three tar distillation facilities in the United States, one in Australia, one in China, one in Denmark and two in the United Kingdom, strategically located to provide access to coal tar and to facilitate better service to our customers with a
consistent supply of high-quality products. In 2009, we will add a second tar distillation facility in China through a 30 percent-owned company. One of our customers, Alcoa, Inc., represents greater than ten percent of our consolidated sales. For
2008, 2007 and 2006, respectively, principal products comprised the following net sales for Carbon Materials & Chemicals:

We believe we have a strategic advantage over our competitors based on our ability to access coal tar from many global
suppliers and subsequently blend such coal tars to produce carbon pitch with the consistent quality important in the manufacturing of quality anodes for the aluminum industry. Our eight coal tar distillation facilities (four of which have port
access) and five carbon pitch terminals give us the ability to offer customers multiple sourcing and a consistent supply of high quality products. In anticipation of potential reductions of U.S. coke capacity, we have secured coal tar supply through
long-term contracts.

Coal tar is purchased from a number of outside sources. Primary suppliers are United States Steel Corporation, Mittal Steel USA, Tangshan
Iron & Steel Co., Ltd., EES Coke Battery, LLC, Novolipetsk Steel, AK Steel Corporation, China Steel Chemical Corporation, Bluescope Steel (AIS) Pty. Limited, OneSteel Manufacturing Pty. Ltd., Corus Group and Mountain States Carbon LLC.

Management believes that our ability to source coal tar and carbon pitch from overseas markets through our foreign operations, as well as our research of petroleum
feedstocks, will assist in securing an uninterrupted supply of carbon pitch feedstocks. However, we may experience shortages of coal tar due to unforeseen circumstances.

Our Carbon Materials & Chemicals business manufactures its primary products and sells them directly to our customers through long-term contracts and purchase orders negotiated by our regional sales personnel and coordinated through
our global marketing group in the United States. We maintain inventories at our plant locations and do not factor our inventories or receivables to third parties.

Coal tar
distillation involves the conversion of coal tar into a variety of intermediate chemical products in processes beginning with distillation. During the distillation process, heat and vacuum are utilized to separate coal tar into three primary
components: carbon pitch (approximately 50 percent), creosote oils (approximately 30 percent) and chemical oils (approximately 20 percent). The below diagram shows the distillation streams derived from coal tar distillation and the primary markets
and products that we sell to:

LOGO

Carbon Pitch

On a global basis, we produce carbon
pitch through the tar distillation process. Sales terms are negotiated by centralized sales departments in the United States, Australia and Europe and are generally evidenced by long-term sales contracts and purchase orders which are coordinated
through our global marketing group at corporate headquarters.

Over 90 percent of our carbon pitch is sold to the aluminum industry, typically under long-term
contracts ranging from three to five years. Many of these long-term contracts have provisions for periodic pricing reviews. Demand for carbon pitch generally fluctuates with production of primary aluminum. Because all coal tar products are produced
in relatively fixed proportion to carbon pitch, the level of carbon pitch consumption generally determines the level of production of other coal tar products. The commercial carbon industry, the second largest user of carbon pitch, uses carbon pitch
to produce electrodes and other specialty carbon products for the steel industry. There are currently no known viable substitutes for carbon pitch in the production of carbon anodes used in the aluminum production process.

Koppers Inc.2008 Annual Report



We have several global competitors in the carbon pitch market, primarily in Europe and Asia. We believe we are the largest producer of carbon pitch for the aluminum industry. Competitive factors in the carbon pitch market
include price, quality, service, and security of supply. We believe we have a competitive advantage based on our global presence and long-term raw material supply contracts.

Naphthalene & Phthalic Anhydride

Chemical oils are further processed to produce naphthalene. In Australia, China and Europe, naphthalene is sold
into the industrial sulfonate market for use as dispersants or in the concrete additive and gypsum board markets. Additional end-uses include oil field additives, agricultural emulsifiers, synthetic tanning agents and dyestuffs.

In the United States, we use naphthalene as a feedstock in the manufacture of phthalic anhydride. We manufacture phthalic anhydride using both naphthalene and externally-sourced
orthoxylene, which is a petroleum derivative. The primary markets for phthalic anhydride are in the production of plasticizers, unsaturated polyester resins and alkyd resins. Sales terms for phthalic anhydride are negotiated by a centralized sales
department in the United States and are generally evidenced by long-term sales contracts and purchase orders.

On a global basis, naphthalene and orthoxylene are both
used as feedstock for the production of phthalic anhydride. However, we are the only North American phthalic anhydride producer capable of utilizing both orthoxylene and naphthalene for this production. Our ability to utilize naphthalene as a
by-product of coal tar distillation gives us a stable supply of feedstock. We believe that our ability to utilize our internally produced naphthalene ordinarily gives us a lower-cost feedstock for the production of phthalic anhydride because
historically our cost to produce naphthalene has been lower than our cost to purchase orthoxylene. We have two primary competitors in the North American phthalic anhydride merchant market.

Creosote & Carbon Black Feedstock

We produce creosote as a co-product of the tar
distillation process. Sales terms for external creosote sales are negotiated by centralized sales departments in the United States, Australia and Europe and are generally evidenced by long-term sales contracts and purchase orders.

In the United States, creosote is used as a commercial wood treatment chemical to preserve railroad crossties and lumber, utility poles and piling. The majority of our domestically
produced creosote is sold to our Railroad & Utility Products business. In Australia, China and Europe, creosote is sold into the carbon black market for use as a feedstock in the production of carbon black. In Australia, the majority of
creosote generated at our tar distillation facility is sold to our carbon black facility. In Europe and China creosote is sold to wood treaters as well as various carbon black producers.

Globally, approximately one-third of our total creosote production was sold internally in 2008. Our wood treating plants in the United States and our carbon black facility in Australia purchase substantially all of their
creosote and carbon black feedstock from our tar distillation plants. We believe we are the only major competitor in these markets that is integrated in this fashion. The remainder of our creosote and carbon black feedstock is sold to railroads,
other wood treaters and carbon black manufacturers. We have several competitors in the creosote market.

Carbon Black

We manufacture carbon black at our plant in Australia using both petroleum oil and coal tar based feedstocks, which are subjected to heat and rapid cooling within a reactor. Coal
tar based carbon black is used in the manufacture of rubber tires as well as other specialty applications.

Other Products

Other products include the sale of refined tars, benzole and specialty chemicals.

Acquisitions
and Dispositions

In October 2008, we sold our 95 percent interest in Koppers Monessen Partners LP (Monessen) to ArcelorMittal S.A. Monessen is a
metallurgical furnace coke facility. In July 2007, we sold our 51 percent interest in Koppers Arch Investments Pty Limited and its subsidiaries (Koppers Arch) to Arch Chemicals Inc. Koppers Arch is a manufacturer of timber
preservation chemicals. Monessen and Koppers Arch were part of our Carbon Materials & Chemicals business segment.

In November 2007,
Tangshan Koppers Kailuan Carbon Chemical Company Limited (TKK) was established which is constructing and will operate a new tar distillation facility in the Hebei Province near the Jingtang Port with a distillation capacity of 300,000
metric tons. We hold a 30 percent investment in TKK which is expected to commence production in the second quarter of 2009. In November 2008, we completed a capacity expansion of our existing 60 percent-owned tar distillation plant in Tangshan,
China from 150,000 metric tons to 200,000 metric tons.

Railroad & Utility Products

We market commercial wood treatment products primarily to the railroad and public utility markets in the United States and Australia. The Railroad & Utility Products business profitability is influenced by the
demand for railroad products by Class 1 railroads, demand for transmission and distribution poles by electric and telephone utilities and its cost to procure wood. For the year ended December 31, 2008, sales of railroad products and services
represented approximately 80 percent of the Railroad & Utility Products business net sales. Railroad products include procuring and treating items such as crossties, switch ties and various types of lumber used for railroad bridges
and crossings. Utility products include transmission and distribution poles for electric and telephone utilities and piling used in industrial foundations, beach housing, docks and piers. The Railroad & Utility Products business operates 15
wood treating plants, one co-generation facility and 12 pole distribution yards located throughout the United States and Australia. Our network of plants is strategically located near timber supplies to enable us to access raw materials and service
customers effectively. In addition, our crosstie treating plants typically abut railroad customers track lines, and our pole distribution yards are typically located near our utility customers.

Our Railroad & Utility Products business manufactures its primary products and sells them directly to our customers through long-term contracts and purchase orders
negotiated by our regional sales personnel and coordinated through our marketing group at corporate headquarters. We maintain inventories at our plant locations and procurement yards and do not factor our inventories or receivables to third parties.

The Railroad & Utility Products business largest customer base is the North American Class 1 railroad market, which buys approximately 80 percent of
all crossties produced in the United States and Canada. We have also been expanding key relationships with some of the approximately 550 short-line and regional rail lines. The railroad crosstie market is a mature market with approximately
21.5 million replacement crossties (both wood and non-wood) purchased during 2008. We currently supply all seven of the North American Class 1 railroads and have contracts with six of the seven North American Class 1 railroads. We have enjoyed
long-standing relationships with this important customer base. We intend to focus on capitalizing on our relationships with railroads by offering an expanded list of complementary product offerings that the railroads may be interested in outsourcing
to us.

We believe we are the largest supplier of railroad crossties in North America. Competitive factors in the railroad crosstie market include price, quality,
service and security of supply. We believe we have a competitive advantage due to our national network of treating plants and direct access to our major customers rail lines, which provide for security of supply and logistics advantages for
our customers.

Hardwoods, such as oak and other species, are the major raw materials in wood crossties. Hardwood prices, which account for approximately 60 percent
of a finished crossties cost, fluctuate with the demand from competing hardwood lumber markets, such as oak flooring, pallets and other specialty lumber products. Normally, raw material price fluctuations are passed through to the customer
according to the terms of the applicable contract. Weather conditions can be a factor in the supply of raw material, as unusually wet conditions may make it difficult to harvest timber.

In the United States, hardwood lumber is procured by us from hundreds of small sawmills throughout the northeastern, midwestern and southern areas of the country. The crossties are shipped via rail car or trucked directly to
one of our ten crosstie treating plants, all of which are on line with a major railroad. The crossties are either air-stacked for a period of six to twelve months or artificially dried by a process called boultonizing. Once dried, the crossties are
pressure treated with creosote, a product of our Carbon Materials & Chemicals business.

Our sales to the railroad industry are coordinated through our
office in Pittsburgh, Pennsylvania, and are primarily from long-term contracts from one to seven years on a minimum requirements basis. There are several principal regional competitors in this North American market.

We believe that the threat of substitution for the wood crosstie is low due to the higher cost of alternative materials. Concrete crossties, however, have been identified by the
railroads as a feasible alternative to wood crossties in limited circumstances. In

Koppers Inc.2008 Annual Report



1991, we acquired a 50 percent interest in KSA Limited Partnership, a concrete crosstie manufacturing facility in Portsmouth, Ohio, in order to take advantage of this
growth opportunity. In 2008, an estimated 1.0 million concrete crossties were installed by Class 1 railroads, representing approximately five percent of total Class 1 crosstie insertions. We believe that concrete crossties will continue to
command approximately this level of market share. While the cost of material has moderated, the cost of installation of a concrete crosstie remains higher than that of a wood crosstie and the average lives of wood and concrete crossties are similar.

Demand for railroad crossties may decline during winter months due to inclement weather conditions which make it difficult to install railroad crossties. As a
result, operating results may vary from quarter to quarter depending on the severity of weather conditions and other variables affecting our products.

Utility poles
are produced mainly from softwoods such as pine in the United States and from hardwoods of the eucalyptus species in Australia. Most of these poles are purchased from large timber owners and individual landowners and shipped to one of our
pole-peeling facilities. While crossties are treated exclusively with creosote, we treat poles with a variety of preservatives, including pentachlorophenol, copper chrome arsenates and creosote.

In the United States the market for utility pole products is characterized by a large number of small, highly competitive producers selling into a price-sensitive industry. The
utility pole market is highly fragmented domestically, with over 200 investor-owned electric and telephone utilities and 2,900 smaller municipal utilities and rural electric associations. In recent years we have seen our utility pole volumes
decrease due to industry deregulation, its impact on maintenance programs, and overcapacity in the pole treating business. We expect demand for utility poles to remain at low levels. In Australia, in addition to utility poles, we market smaller
poles to the agricultural, landscape and vineyard markets.

During 2008, sales of pole products accounted for approximately 20 percent of Railroad & Utility
Products net sales. We have eight principal competitors in the U.S. utility products market. There are few barriers to entry in the utility products market, which consists primarily of regional wood treating companies operating small to
medium-size plants and serving local markets.

Equity Investments

KSA Limited
Partnership, located in Portsmouth, Ohio, produces concrete crossties, a complementary product to our wood treatment crosstie business. We own 50 percent of KSA, with the other 50 percent owned by subsidiaries of Heidelberg Cement AG. KSA Limited
Partnership also provides concrete turnouts, used in rail traffic switching, and used crosstie rehabilitation.

TKK was established in November 2007 and is
constructing and will operate a new tar distillation facility in the Hebei Province near the Jingtang Port. The Company holds a 30 percent investment in TKK which is expected to commence production in the second quarter of 2009.

Research and Development

Our research efforts are directed toward new product development
regarding alternate uses for coal tar and technical service efforts to promote the use of creosote and vacuum-distilled carbon pitch. We believe the research and technical efforts provided in these areas are adequate to maintain a leadership
position in the technology related to these products. Expenditures for research and development were $2.8 million, $2.8 million and $2.5 million, for the years ended December 31, 2008, 2007 and 2006, respectively.

Technology and Licensing

In 1988, we acquired certain assets from Koppers Company, Inc.,
including the patents, patent applications, trademarks, copyrights, transferable licenses, inventories, trade secrets and proprietary processes used in the businesses acquired. The most important trademark acquired was the name Koppers.
The association of the name with the chemical, building, wood preservation and coke industries is beneficial to our company, as it represents long-standing, high quality products. As long as we continue to use the name Koppers and comply
with applicable registration requirements, our right to use the name Koppers should continue without expiration. The expiration of other intellectual property rights is not expected to materially affect our business.

Backlog

Generally, Koppers does not manufacture its products against a backlog of orders.
Inventory and production levels are typically driven by expectations of future demand based on contractual obligations.

the severity of weather conditions and other variables affecting our products.

Segment Information

Please see Note 9, Segment Information, under Item 8 of this Form 10-K for financial information relating to business segments.

Non-U.S. Operations

Koppers has a significant investment in non-U.S. operations. Therefore, we are subject to certain risks that are inherent to foreign
operations, including political and economic conditions in international markets and fluctuations in foreign exchange rates. While a significant majority of our sales and income is generated by operations in the United States, the United Kingdom,
Denmark and Australia, our remaining sales and income are generated from operations in developing regions, such as China and the Middle East.

Environmental Matters

Our operations and properties are subject to extensive federal, state, local and foreign environmental laws and regulations relating to protection of the environment
and human health and safety, including those concerning the treatment, storage and disposal of wastes, the investigation and remediation of contaminated soil and groundwater, the discharge of effluents into waterways, the emission of substances into
the air, as well as various health and safety matters. Environmental laws and regulations are subject to frequent amendment and have historically become more stringent. We have incurred and could incur in the future significant costs as the result
of our failure to comply with, and liabilities under, environmental laws and regulations, including cleanup costs, civil and criminal penalties, injunctive relief and denial or loss of, or imposition of significant restrictions on, environmental
permits. In addition, we have been and could in the future be subject to suit by private parties in connection with alleged violations of, or liabilities under, environmental laws and regulations.

We accrue for environmental liabilities when a determination can be made that they are probable and reasonably estimable. Total environmental reserves at December 31, 2008 and
2007 were $11.7 million and $12.5 million, respectively, which include provisions primarily for environmental fines and remediation. For the last three years, our annual capital expenditures in connection with environmental control facilities
averaged approximately $6.0 million and annual operating expenses for environmental matters, excluding depreciation, averaged approximately $12.8 million. Management estimates that capital expenditures in connection with matters relating to
environmental control facilities will be approximately $10.2 million for 2009. We believe that we will have continuing significant expenditures associated with compliance with environmental laws and regulations and, to the extent not covered by
insurance or available recoveries under third-party indemnification arrangements, for present and future remediation efforts at plant sites and third-party waste sites and other liabilities associated with environmental matters. There can be no
assurance that these expenditures will not exceed current estimates and will not have a material adverse effect on our business, financial condition, cash flow and results of operations. See Note 19 of the Notes to Consolidated Financial Statements,
Commitments and Contingent Liabilities.

Employees and Employee Relations

As of December 31, 2008, we had 604 salaried employees and 1,143 non-salaried employees. Listed below is a breakdown of employees by our businesses, including administration.

ITEM 1A. RISK FACTORS

You should
carefully consider the risks described below before investing in our publicly traded securities. The risks described below are not the only ones facing us. Our business is also subject to the risks that affect many other companies, such as
competition, technological obsolescence, labor relations, general economic conditions, geopolitical events and international operations. Additional risks not currently known to us or that we currently believe are immaterial may also impair our
business operations and our liquidity.

Risks Relating to Our Business

Conditions in the global economy and global capital markets may adversely affect our results of operations, financial condition and cash flows.

Starting in
2008 and continuing in 2009, the U.S and global economy have undergone a sudden, sharp economic downturn. Global credit and capital markets have experienced unprecedented volatility and disruption, and business credit and liquidity have tightened in
much of the world. Consumer confidence and spending are down significantly and the rates of unemployment and underemployment are increasing. As a result of current economic conditions, including turmoil and uncertainty in the capital markets, credit
markets have tightened significantly such that the ability to obtain new capital has become more challenging and more expensive. Several large financial institutions have either recently failed or been dependent on the assistance of the U.S. federal
government to continue to operate as a going concern. It is difficult to determine the breadth and duration of the economic and financial market problems and the many ways in which they may affect our suppliers, customers and business in general.
Nonetheless, continuation or further worsening of these difficult financial and macroeconomic conditions could have a significant adverse effect on our sales, profitability and results of operations. Our business and operating results for 2008 were
affected by these global economic issues, and we expect that trend to continue in 2009. Many of our customers have experienced (and will likely continue to experience) deterioration of their business. They may experience cash flow shortages and may
have difficulty obtaining financing. As a result, our customers may delay or cancel plans to purchase our products and may not be able to fulfill their payment obligations to us in a timely fashion. Our suppliers may be experiencing similar
conditions which could impact their ability to supply us with raw materials and otherwise fulfill their obligations to us. If the global economic recession continues for an extended period or deteriorates significantly, there could be a material
adverse effect to our results of operations, financial condition and cash flows.

In addition, we rely on our $300.0 million revolving credit agreement with a
consortium of banks to provide us with liquidity to meet our working capital needs. At December 31, 2008, we had $283.0 million of available borrowing capacity under this arrangement. Our ability to fund our liquidity needs and working capital
requirements could be impacted in the event that disruptions in the credit markets result in the banks being unable to lend to us under our revolving credit agreement.

Global economic issues could prevent us from accurately forecasting demand for our products which could have a material effect on our results of operations and our financial condition.

Adverse global economic issues, market instability and volatile commodity price fluctuations make it increasingly difficult for us, our customers and our suppliers to accurately
forecast future product demands, which could cause us to procure raw materials in excess of end-product demand. This could cause a material increase to our inventory carrying costs and result in significant inventory lower of cost or market charges.

We may be required
to recognize impairment charges for our long-lived assets.

At December 31, 2008, the net carrying value of long-lived assets (property, plant and equipment,
goodwill and other intangible assets) totaled approximately $229.6 million. In accordance with generally accepted accounting principles, we periodically assess these assets to determine if they are impaired. Significant negative industry or economic
trends, disruptions to our business, unexpected significant changes or planned changes in use of the assets, divestitures and market capitalization declines may result in impairments to goodwill and other long-lived assets. Future impairment charges
could significantly affect our results of operations in the periods recognized. Impairment charges would also reduce our stockholders equity and could affect compliance with the covenants in our debt agreements.

We may not be able to compete successfully in any or all of the industry segments in which we operate.

The markets in which we operate are highly competitive, and this competition could harm our business, results of operations, cash flow and financial condition. If we are unable to respond successfully to changing competitive conditions, the
demand for our products could be affected. We believe that the most significant competitive factor for our products is selling price. Some of our competitors have greater financial resources and larger capitalization than we do.

Demand for our products is cyclical and we may experience prolonged depressed market conditions for our products.

Our products are sold primarily in mature markets which historically have been cyclical, such as the aluminum, specialty chemical and utility industries.



| | ¡ |  | The principal consumers of our carbon pitch are primary aluminum smelters. Although the aluminum industry has experienced growth on a long-term basis, there may be cyclical
periods of weak demand which could result in decreased primary aluminum production. Our pitch sales have historically declined during such cyclical periods of weak global demand for aluminum.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ¡ |  | The principal use of our phthalic anhydride is in the manufacture of plasticizers and flexible vinyl, which are used mainly in the housing and automobile industries.
Therefore, a decline in remodeling and construction or global automobile production could reduce the demand for phthalic anhydride.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ¡ |  | Over the last several years, utility pole demand has declined as utilities in the United States and Australia have reduced spending due to competitive pressures arising from
deregulation. Deregulation may continue to negatively affect both the new and replacement pole installation markets.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We are currently experiencing
significant volatility linked to global economic issues that we more fully discuss in Managements Discussion and Analysis of Financial Condition and Results of Operations.

We are dependent on major customers for a significant portion of our net sales, and the loss of one or more of our major customers could result in a significant reduction in our profitability.

For the year ended December 31, 2008, our top ten customers accounted for approximately 50 percent of our net sales. During this period, our two largest customers each
accounted for ten percent and eight percent, respectively, of our total net sales. The permanent loss of, or a significant decrease in the level of purchases by, one or more of our major customers could result in a significant reduction in our
profitability.

Our largest customer has significantly reduced their purchases of carbon pitch starting in the fourth quarter of 2008. We believe that this reduction
is linked to global economic issues that we more fully discuss in Managements Discussion and Analysis of Financial Condition and Results of Operations.

Fluctuations in the price, quality and availability of our primary raw materials could reduce our profitability.

Our operations depend on an adequate supply
of quality raw materials being available on a timely basis. The loss of a key source of supply or a delay in shipments could cause a significant increase in our operating expenses. For example, our operations are highly dependent on a relatively
small number of freight transportation services. We are also dependent on utilizing specialized ocean-going transport vessels that we lease to deliver raw materials to our facilities and finished goods to



12

##### Table of Contents

Koppers Inc.2008 Annual Report



our customers. Interruptions in such freight services could impair our ability to receive raw materials and ship finished products in a timely manner. We are also
exposed to price and quality risks associated with raw material purchases. Such risks include the following:



| | ¡ |  | The primary raw material used by our Carbon Materials & Chemicals business is coal tar, a by-product of furnace coke production. A shortage in the supply of domestic
coal tar or a reduction in the quality of coal tar could require us to increase coal tar and carbon pitch imports, as well as the use of petroleum substitutes to meet future carbon pitch demand. This could cause a significant increase in our
operating expenses if we are unable to pass these costs on to our customers.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Currently, we are experiencing reduced receipts of
coal tar as furnace coke producers have significantly reduced the production of furnace coke due to global economic issues that we more fully discuss in Managements Discussion and Analysis of Financial Condition and Results of Operations.



| | ¡ |  | In certain circumstances coal tar may also be used as an alternative to fuel. In the past, increases in energy prices have resulted in higher coal tar costs which we have
attempted to pass through to our customers. If these increased costs cannot be passed through to our customers, it could result in margin reductions for our coal tar-based products.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ¡ |  | The availability and cost of softwood and hardwood lumber are critical elements in our production of pole products and railroad crossties, respectively. The supply of trees
of acceptable size for the production of utility poles has decreased in recent years in relation to the demand, and we have been required to pay a higher price for these materials. Historically, the supply and cost of hardwood for railroad crossties
have also been subject to availability and price pressures. We may not be able to source wood raw materials at economical prices in the future.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ¡ |  | Our price realizations and profit margins for phthalic anhydride have historically fluctuated with the price of orthoxylene and its relationship to our cost to produce
naphthalene; however, during periods of excess supplies of phthalic anhydride, margins may be reduced despite high levels for orthoxylene prices.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If the costs of raw materials increase significantly and we are unable to offset the increased costs with higher selling prices, our profitability will decline.

Our products may be rendered obsolete or less attractive by changes in regulatory, legislative or industry requirements.

Changes in regulatory, legislative
or industry requirements may render certain of our products obsolete or less attractive. Our ability to anticipate changes in these requirements, especially changes in regulatory standards, will be a significant factor in our ability to remain
competitive. We may not be able to comply in the future with new regulatory, legislative and/or industrial standards that may be necessary for us to remain competitive and certain of our products may, as a result, become obsolete or less attractive
to our customers.

The development of new technologies or changes in our customers products could reduce the demand for our products.

Our products are used for a variety of applications by our customers. Changes in our customers products or processes may enable our customers to reduce consumption of the
products we produce or make our products unnecessary. Customers may also find alternative materials or processes that no longer require our products. For example, in 2000 our largest carbon pitch customer announced that it was actively pursuing
alternative anode technology that would eliminate the need for carbon pitch as an anode binder. The potential development and implementation of this new technology could seriously impair our ability to profitably market carbon pitch and related
co-products. A substantial portion of our carbon pitch is sold to the aluminum industry under long-term contracts typically ranging from three to five years. If a new technology were developed that replaced the need for carbon pitch in the
production of carbon anodes, it is possible that these contracts would not be renewed in the future.

Hazards associated with chemical manufacturing may cause
suspensions or interruptions of our operations.

Due to the nature of our business, we are exposed to the hazards associated with chemical manufacturing and the
related storage and transportation of raw materials, products and wastes in our manufacturing facilities or our distribution centers,



13



---

##### Table of Contents



such as fires, explosions and accidents that could lead to an interruption or suspension of operations. Any disruption could reduce
the productivity and profitability of a particular manufacturing facility or of our company as a whole. Other hazards include the following:



| | ¡ |  | piping and storage tank leaks and ruptures;
| | - |  | -------------------------------------------



| | ¡ |  | mechanical failure;
| | - |  | -------------------



| | ¡ |  | exposure to hazardous substances; and
| | - |  | -------------------------------------



| | ¡ |  | chemical spills and other discharges or releases of toxic or hazardous substances or gases.
| | - |  | -------------------------------------------------------------------------------------------

These hazards, among others, may cause personal injury and loss of life, damage to property and contamination of the environment, which could lead to government fines or work stoppage injunctions, cleanup costs and lawsuits by
injured persons. While we are unable to predict the outcome of such matters, if determined adversely to us, we may not have adequate insurance to cover related costs or liabilities and, if not, we may not have sufficient cash flow to pay for such
costs or liabilities. Such outcomes could harm our customer goodwill and reduce our profitability.

We are subject to extensive environmental laws and regulations
and may incur significant costs as a result of continued compliance with, violations of or liabilities under environmental laws and regulations.

Like other companies
involved in environmentally sensitive businesses, our operations and properties are subject to extensive federal, state, local and foreign environmental laws and regulations, including those concerning the following, among other things:



| | ¡ |  | the treatment, storage and disposal of wastes;
| | - |  | ----------------------------------------------



| | ¡ |  | the investigation and remediation of contaminated soil and groundwater;
| | - |  | -----------------------------------------------------------------------



| | ¡ |  | the discharge of effluents into waterways;
| | - |  | ------------------------------------------



| | ¡ |  | the emission of substances into the air;
| | - |  | ----------------------------------------



| | ¡ |  | the marketing, sale, use and registration of our chemical products, such as creosote; and
| | - |  | -----------------------------------------------------------------------------------------



| | ¡ |  | other matters relating to environmental protection and various health and safety matters.
| | - |  | -----------------------------------------------------------------------------------------

We have incurred, and expect to continue to incur, significant costs to comply with environmental laws and as a result of remedial obligations. We could incur significant costs, including cleanup costs, fines, civil and
criminal sanctions and claims by third parties for property damage and personal injury, as a result of violations of or liabilities under environmental laws and regulations. We accrue for environmental liabilities when a determination can be made
that they are probable and reasonably estimable. Total environmental reserves at December 31, 2008 and December 31, 2007 were $11.7 million and $12.5 million, respectively, which include provisions primarily for environmental fines and
remediation. For the last three fiscal years, our annual capital expenditures in connection with environmental control facilities averaged approximately $6.0 million, and annual operating expenses for environmental matters, excluding depreciation,
averaged approximately $12.8 million. Management estimates that capital expenditures in connection with matters relating to environmental control facilities will be approximately $10.2 million for 2009. Contamination has been identified and is being
investigated and remediated at many of our sites by us or other parties.

Actual costs and liabilities to us may exceed forecasted amounts. Moreover, currently
unknown environmental issues, such as the discovery of additional contamination or the imposition of additional sampling or cleanup obligations with respect to our sites or third party sites, may result in significant additional costs, and
potentially significant expenditures could be required in order to comply with future changes to environmental laws and regulations or the interpretation or enforcement thereof. We also are involved in various litigation and proceedings relating to
environmental matters and toxic tort claims which are described in detail in Note 19 of the consolidated financial statements.

Beazer East and Beazer Limited may
not continue to meet their obligations to indemnify us.

Under the terms of the asset purchase agreement between us and Koppers Company, Inc. (now known as Beazer
East, Inc.) upon the formation of Koppers Inc. in 1988, subject to certain limitations, Beazer East and Beazer Limited assumed the liability for and indemnified us against (among other things) certain clean-up liabilities for contamination occurring
prior to the



14

##### Table of Contents

Koppers Inc.2008 Annual Report



purchase date at sites acquired from Beazer East and third-party claims arising from such contamination (the Indemnity). Beazer East and Beazer Limited
(which are indirect subsidiaries of Heidelberg Cement AG) may not continue to meet their obligations. In addition, Beazer East could in the future choose to challenge its obligations under the Indemnity or our satisfaction of the conditions to
indemnification imposed on us thereunder. In addition, the government and other third parties also have the right under applicable environmental laws to seek relief directly from us for any and all such costs and liabilities. In July 2004, we
entered into an agreement with Beazer East to amend the December 29, 1988 asset purchase agreement to provide, among other things, for the continued tender of pre-closing environmental liabilities to Beazer East under the Indemnity through July
2019. As consideration for the agreement, we agreed to pay Beazer East a total of $7.0 million in four installments over three years and to share toxic tort litigation defense costs arising from any sites acquired from Beazer East. Qualified
expenditures under the Indemnity are not subject to a monetary limit.

The Indemnity provides for the resolution of issues between Koppers Inc. and Beazer East by an
arbitrator on an expedited basis upon the request of either party. The arbitrator could be asked, among other things, to make a determination regarding the allocation of environmental responsibilities between Koppers Inc. and Beazer East.
Arbitration decisions under the Indemnity are final and binding on the parties. Periodically, issues have arisen between Koppers Inc. and Beazer East and/or other indemnitors that have been resolved without arbitration. From time to time, Koppers
Inc. and Beazer East have engaged in discussions that involve, among other things, the allocation of environmental costs related to certain operating and closed facilities.

Without reimbursement under the Indemnity, the obligation to pay the costs and assume the liabilities relating to these matters would have a significant impact on our net income. Furthermore, without reimbursement, we could be required to
record a contingent liability on our balance sheets with respect to environmental matters covered by the Indemnity, which could result in our having significant negative net worth. Finally, the Indemnity does not afford us indemnification against
environmental costs and liabilities attributable to acts or omissions occurring after the closing of the acquisition of assets from Beazer East under the asset purchase agreement, nor is the Indemnity applicable to liabilities arising in connection
with other acquisitions by us after that closing.

The insurance that we maintain may not fully cover all potential exposures.

We maintain property, casualty, general liability and workers compensation insurance, but such insurance may not cover all risks associated with the hazards of our business
and is subject to limitations, including deductibles and maximum liabilities covered. We may incur losses beyond the limits, or outside the coverage, of our insurance policies, including liabilities for environmental compliance and remediation. In
addition, from time to time, various types of insurance for companies in our industry have not been available on commercially acceptable terms or, in some cases, have not been available at all. In the future, we may not be able to obtain coverage at
current levels, and our premiums may increase significantly on coverage that we maintain.

Adverse weather conditions may reduce our operating results.

Our quarterly operating results fluctuate due to a variety of factors that are outside our control, including inclement weather conditions, which in the past have caused a
decline in our operating results. For example, adverse weather conditions have at times negatively impacted our supply chain as wet conditions impacted logging operations, reducing our ability to procure crossties. In addition, adverse weather
conditions have had a negative impact on our customers in the pavement sealer businesses, resulting in a negative impact on our sales of these products. Moreover, demand for many of our products declines during periods of inclement weather.

We are subject to risks inherent in foreign operations, including changes in social, political and economic conditions.

We have operations in the United States, Australia, China and Europe, and sell our products in many foreign countries. For the year ended December 31, 2008, net sales from
products sold by our foreign subsidiaries accounted for approximately 38 percent of our total net sales. Like other global companies, we are exposed to market risks relating to fluctuations in interest rates and foreign currency exchange rates. Our
international revenues could be reduced by currency fluctuations or devaluations. Changes in currency exchange rates could lower our reported revenues and could require us to reduce our prices to remain competitive in foreign markets, which could
also reduce our profitability. We have not historically hedged our financial statement exposure and, as a result, we could incur unanticipated losses. We are also subject to potentially increasing transportation and shipping costs associated with
international operations.

Furthermore, we are
also exposed to risks associated with changes in the laws and policies governing foreign investments in countries where we have operations as well as, to a lesser extent, changes in U.S. laws and regulations relating to foreign trade and investment.

Our strategy to selectively pursue complementary acquisitions may present unforeseen integration obstacles or costs.

Our business strategy includes the potential acquisition of businesses and entering into joint ventures and other business combinations that we expect would complement and expand
our existing products and the markets where we sell our products. We may not be able to successfully identify suitable acquisition or joint venture opportunities or complete any particular acquisition, combination, joint venture or other transaction
on acceptable terms. We cannot predict the timing and success of our efforts to acquire any particular business and integrate the acquired business into our existing operations. Also, efforts to acquire other businesses or the implementation of
other elements of this business strategy may divert managerial resources away from our business operations. In addition, our ability to engage in strategic acquisitions may depend on our ability to raise substantial capital and we may not be able to
raise the funds necessary to implement our acquisition strategy on terms satisfactory to us, if at all. Our failure to identify suitable acquisition or joint venture opportunities may restrict our ability to grow our business. In addition, we may
not be able to successfully integrate businesses that we acquire in the future, which could lead to increased operating costs, a failure to realize anticipated operating synergies, or both.

Litigation against us could be costly and time-consuming to defend, and due to the nature of our business and products, we may be liable for damages arising out of our acts or
omissions, which may have a material adverse affect on us.

We produce chemicals that require appropriate procedures and care to be used in handling them or using
them to manufacture other products. As a result of the nature of some of the products we use and produce, we may face product liability, toxic tort and other claims relating to incidents involving the handling, storage and use of and exposure to our
products.

For example, we are a defendant in a significant number of lawsuits in which the plaintiffs claim they have suffered a variety of illnesses (including
cancer) and/or property damage as a result of exposure to coal tar pitch, benzene, wood treatment chemicals and other chemicals, including certain cases in state and federal court relating to our Grenada, Mississippi and Somerville, Texas
facilities. A further description of the material claims against us is included in Note 19 of the consolidated financial statements.

We are indemnified for certain
product liability exposures under the Indemnity with Beazer East related to products sold prior to the closing of the acquisition of assets from Beazer East. Beazer East and Beazer Limited may not continue to meet their obligations under the
Indemnity. In addition, Beazer East could choose to challenge its obligations under the Indemnity or our satisfaction of the conditions to indemnification imposed on us thereunder.

If for any reason (including disputed coverage or financial incapability) one or more of such parties fail to perform their obligations and we are held liable for or otherwise required to pay all or part of such liabilities
without reimbursement, the imposition of such liabilities on us could have a material adverse effect on our business, financial condition, cash flows and results of operations. Furthermore, we could be required to record a contingent liability on
our balance sheets with respect to such matters, which could result in us having significant additional negative net worth.

In addition to the above, we are
regularly subject to legal proceedings and claims that arise in the ordinary course of business, such as workers compensation claims, governmental investigations, employment disputes, and customer and supplier disputes arising out of the
conduct of our business. Litigation could result in substantial costs and may divert managements attention and resources away from the day-to-day operation of our business.

Labor disputes could disrupt our operations and divert the attention of our management and may cause a decline in our production and a reduction in our profitability.

Of our employees, approximately 65 percent are represented by approximately 15 different labor unions and are covered under numerous labor agreements. The United Steelworkers of
America currently represent approximately 350 of our employees at six of our facilities and, therefore, represent the largest number of our unionized employees. The four labor agreements that expire in 2009 cover approximately 16 percent of our
total workforce. We may not be able to reach new agreements without union

action or on terms satisfactory to us. Any future labor disputes with any such unions could result in strikes or other labor protests, which could disrupt our
operations and divert the attention of our management from operating our business. If we were to experience a strike or work stoppage, it may be difficult for us to find a sufficient number of employees with the necessary skills to replace these
employees. Any such labor disputes could cause a decline in our production and a reduction in our profitability.

Our post-retirement obligations are currently
underfunded. We expect to make significant cash payments to our pension and other post-retirement plans, which will reduce the cash available for our business.

As of
December 31, 2008, our benefit obligation under our defined benefit pension plans exceeded the fair value of plan assets by approximately $63.5 million. Our pension asset funding to total pension obligation ratio was 64 percent as of
December 31, 2008. The underfunding was caused, in large part, by fluctuations in the financial markets that have caused the value of the assets in our defined benefit pension plans to be significantly lower than anticipated. For example, our
pension assets declined in value by $43.0 million during 2008. In addition, our obligations for other post-retirement benefit obligations are unfunded and total $13.6 million at December 31, 2008.

During the years ended December 31, 2008 and December 31, 2007, we contributed $3.3 million and $13.5 million, respectively, to our post-retirement benefit plans. In
2009, we estimate that mandatory funding obligations will be approximately $3 million for all of our post-retirement plans. With respect to our U.S. defined benefit pension plan which is our largest plan, we have no mandatory funding obligation in
2009. However, we estimate that mandatory funding for this plan will be approximately $20 million in 2010 and $30 million in 2011 unless legislative relief is granted.

Management expects that any future obligations under our post-retirement benefit plans that are not currently funded will be funded from our future cash flow from operations. If our contributions to our post-retirement benefit plans are
insufficient to fund the post-retirement benefit plans adequately to cover our future obligations, the performance of the assets in our pension plans does not meet our expectations or other actuarial assumptions or mandatory funding laws are
modified, our contributions to our post-retirement benefit plans could be materially higher than we expect, thus reducing the cash available for our business.

We
have a substantial amount of indebtedness, which could harm our ability to operate our business, remain in compliance with debt covenants, make payments on our debt and pay dividends.

As of December 31, 2008, we and our subsidiaries had approximately $188.3 million of indebtedness (excluding trade payables and intercompany indebtedness), consisting primarily of our Senior Secured Notes.

The degree to which we are leveraged could have important consequences, including the following:



| | ¡ |  | our ability to satisfy our obligations under our debt could be affected and any failure to comply with the requirements, including financial and other restrictive covenants,
of any of our debt agreements could result in an event of default under the agreements governing such indebtedness;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ¡ |  | a substantial portion of our cash flow from operations will be required to make interest and principal payments and may not be available for operations, working capital,
capital expenditures, expansion, acquisitions or general corporate or other purposes;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ¡ |  | our ability to obtain additional financing in the future may be impaired;
| | - |  | -------------------------------------------------------------------------



| | ¡ |  | we may be more highly leveraged than our competitors, which may place us at a competitive disadvantage;
| | - |  | -------------------------------------------------------------------------------------------------------



| | ¡ |  | our flexibility in planning for, or reacting to, changes in our business and industry may be limited;
| | - |  | -----------------------------------------------------------------------------------------------------



| | ¡ |  | our degree of leverage may make us more vulnerable in the event of a downturn in our business, our industry or the economy in general; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| | ¡ |  | our ability to pay dividends to our shareholders may be impaired.
| | - |  | -----------------------------------------------------------------

Furthermore, we and our subsidiaries may be able to incur substantial additional indebtedness in the future. If we incur additional indebtedness, the magnitude of the risks associated with our substantial leverage, including our ability to
service our debt, would increase.

##### Table of Contents



Restrictions in our
debt agreements could limit our growth and our ability to respond to changing conditions and, in the event of a default, all of these borrowings become immediately due and payable.

Koppers Inc.s revolving credit facility and the indentures governing our Senior Secured Notes contain a number of significant covenants in addition to covenants restricting the incurrence of additional debt. Among other
things these covenants limit our ability to



| | ¡ |  | incur or guarantee additional debt and issue certain types of preferred stock;
| | - |  | ------------------------------------------------------------------------------



| | ¡ |  | pay dividends on our capital stock or redeem, repurchase or retire our capital stock or subordinated debt;
| | - |  | ----------------------------------------------------------------------------------------------------------



| | ¡ |  | make investments;
| | - |  | -----------------



| | ¡ |  | create liens on our assets;
| | - |  | ---------------------------



| | ¡ |  | enter into sale and leaseback transactions;
| | - |  | -------------------------------------------



| | ¡ |  | sell assets;
| | - |  | ------------



| | ¡ |  | engage in transactions with our affiliates;
| | - |  | -------------------------------------------



| | ¡ |  | create restrictions on the ability of our restricted subsidiaries to pay dividends or make other payments to us;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| | ¡ |  | consolidate, merge or transfer all or substantially all of our assets and the assets of our subsidiaries; and
| | - |  | -------------------------------------------------------------------------------------------------------------



| | ¡ |  | transfer or issue shares of stock of subsidiaries.
| | - |  | --------------------------------------------------

In addition, Koppers
Inc.s revolving credit facility contains other and more restrictive covenants. Additionally, it requires us to maintain certain financial ratios and satisfy certain financial condition tests and require us to take action to reduce our debt or
take some other action to comply with them.

These restrictions could limit our ability to obtain future financings, make needed capital expenditures, withstand a
downturn in our business or the economy in general or otherwise conduct necessary corporate activities. We may also be prevented from taking advantage of business opportunities that arise because of the limitations that the restrictive covenants
under Koppers Inc.s revolving credit facility and the indentures governing our Senior Secured Notes impose on us.

A breach of any of these covenants would
result in a default under the applicable debt agreement. A default, if not waived, could result in acceleration of the debt outstanding under that agreement and in a default with respect to, and acceleration of, the debt outstanding under our other
debt agreements and the indentures governing our Senior Secured Notes. The accelerated debt would become immediately due and payable. If that should occur, we may not be able to pay all such debt or to borrow sufficient funds to refinance it. This
would result in a significant interruption in our business operations, which would negatively impact the market price of our common stock. Even if new financing were then available, it may not be on terms that are acceptable to us.

We may incur significant charges in the event we close all or part of a manufacturing plant or facility.

We periodically assess our manufacturing operations in order to manufacture and distribute our products in the most efficient manner. Based on our assessments, we may make capital improvements to modernize certain units, move manufacturing
or distribution capabilities from one plant or facility to another plant or facility, discontinue manufacturing or distributing certain products or close all or part of a manufacturing plant or facility.

We depend on our senior management team and the loss of any member could adversely affect our operations.

Our success is dependent on the management, experience and leadership skills of our senior management team. Our senior management team has an average of over 20 years of industry experience. The loss of any of these individuals
or an inability to attract, retain and maintain additional personnel with similar industry experience could prevent us from implementing our business strategy. We cannot assure you that we will be able to retain our existing senior management
personnel or to attract additional qualified personnel when needed.

PART II

ITEM 5. MARKET FOR THE REGISTRANTS COMMON EQUITY, RELATED STOCKHOLDER MATTERS
AND ISSUER PURCHASES OF EQUITY SECURITIES

In November 2004, all of our common and preferred stock was converted on a one-for-one basis for shares of common and
preferred stock of Koppers Holdings Inc., our parent, which was incorporated in November 2004. As a result, Koppers Holdings is our sole shareholder, and therefore there is no public trading market for our common stock.

As further described in Item 7, Managements Discussion and Analysis of Financial Condition and Results of Operations, we are restricted in our ability to
declare and pay dividends to our parent, Koppers Holdings Inc. In 2008, 2007 and 2006 the Company paid cash dividends of $38.4 million, $14.7 million and $16.6 million, respectively.

Koppers Inc.2008 Annual Report



ITEM 7. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

We are a leading integrated global provider of carbon compounds and
commercial wood treatment products. Our products are used in a variety of niche applications in a diverse range of end-markets, including the aluminum, railroad, specialty chemical, utility, rubber and steel industries. We serve our customers
through a comprehensive global manufacturing and distribution network, which includes manufacturing facilities located in the United States, Australia, China, the United Kingdom and Denmark.

We operate two principal businesses: Carbon Materials & Chemicals (CM&C) and Railroad & Utility Products (R&UP). We
believe that our CM&C business is the largest distiller of coal tar in North America, Australia, the United Kingdom and Scandinavia. We process coal tar into a variety of products, including carbon pitch, creosote and phthalic anhydride, which
are critical intermediate materials in the production of aluminum, the pressure treatment of wood and the production of plasticizers and specialty chemicals, respectively. We believe that our R&UP business is the largest North American supplier
of railroad crossties. Our other commercial wood treatment products include the provision of utility poles to the electric and telephone utility industries.

Our
CM&C business has entered into a number of strategic transactions during the last two years to expand and focus on its core business related to coal tar distillation and derived products. In November 2007, Tangshan Koppers Kailuan Carbon
Chemical Company Limited (TKK) was established which is constructing and will operate a new tar distillation facility in the Hebei Province near the Jingtang Port with a distillation capacity of 300,000 metric tons. We hold a 30 percent
investment in TKK which is expected to commence production in the second quarter of 2009. In November 2008, we completed a project to expand the capacity of our existing 60-percent owned tar distillation plant in Tangshan, China from 150,000 metric
tons to 200,000 metric tons.

On October 1, 2008, we sold our 95 percent interest in Koppers Monessen Partners LP (Monessen) to ArcelorMittal S.A.
for cash of $160.0 million plus working capital of $10.4 million. Net cash proceeds, after deduction for the limited partner interest, taxes and transaction costs, were approximately $100.0 million. The Company recognized an after-tax gain of $85.9
million. Monessen is a metallurgical furnace coke facility. Effective as of the end of the second quarter of 2008, Monessen was classified as a discontinued operation in the Companys statement of operations and its assets and liabilities were
reclassified as held for sale in the balance sheet. Accordingly our financial statements have been restated for prior periods.

In July 2007, we sold
our 51 percent interest in Koppers Arch Investments Pty Limited and its subsidiaries (Koppers Arch) to Arch Chemicals Inc. for net cash proceeds of $14.3 million and recognized a gain from the sale, net of tax, of $6.7 million. Effective
as of this date, Koppers Arch was classified as a discontinued operation in our statement of operations and our financial statements have been accordingly restated. Koppers Arch was a manufacturer of timber preservation chemicals.

Monessen and Koppers Arch were part of our Carbon Materials & Chemicals business segment.

Outlook

Trend Overview

Our businesses and results of operations
are impacted by various competitive and other factors including (i) the impact of global economic conditions on demand for our products both in the United States and overseas; (ii) raw materials pricing and availability, in particular the
amount and quality of coal tar available in global markets, which could be negatively impacted by reductions in steel production; (iii) volatility in oil prices, which impacts selling prices and margins for certain of our products including
carbon black feedstocks and phthalic anhydride; (iv) competitive conditions in global carbon pitch markets; (v) low margins in the utility pole business; and (vi) changes in foreign exchange rates.

Our businesses and results of operations have been impacted by the downturn in the global economy in late 2008 and we expect that these negative trends will continue in 2009.
Certain key end markets have experienced significant global reductions in demand that will negatively impact the demand for our products. In late 2008 and continuing into 2009 we have seen



23



---

##### Table of Contents



significant reductions in global production of aluminum, steel, rubber, concrete, plastics and paints, among others, that represent
markets in which our products are consumed. We are watching these markets very closely and believe that there will be uncertainty regarding the levels of production going forward. Due to the nature of our end markets, we could see some level of
demand improvement as government stimulus is introduced.

In recent months we have seen the temporary idling or closure of several aluminum smelters. We expect the
trend of closing or reducing production at higher cost smelters to continue as newer, more cost effective smelters come on line in regions with lower cost energy, particularly in the Middle East. As an example we have seen specific closures in North
America and Europe that will negatively impact volumes in those geographic areas; at this time we can not predict if or when these idled smelters will return to production. However, we believe we are well positioned to supply the new Middle Eastern
smelters due to our capacity expansions in China.

We expect to produce lower volumes in 2009 in many of our products which will impact the capacity utilization at
our facilities. Lower throughput volumes combined with increasing pressure for price reductions has led us to review our capacity utilization and has resulted in production cutbacks at certain facilities, which will result in lower margins. If these
trends continue, we may temporarily idle or permanently close facilities. Utility pole markets are expected to continue to remain competitive with resulting low margins. We will continue to review underperforming assets and rationalize capacity as
necessary to remain competitive in this market and will reduce market share if warranted.

Several of our products, particularly carbon black feedstocks and phthalic
anhydride, have end market pricing that is linked to benchmark oil indices. During the past few years we have benefited in terms of revenues and profitability from the higher pricing for these products as the cost of coal tar has not increased
proportionally with oil. However, when the price of oil declined in late 2008 we saw significant price and profit declines for these products that we expect will continue in 2009.

The availability of a key raw material, coal tar, is linked to levels of metallurgical coke production. As the global steel industry has reduced production of steel and metallurgical coke the volumes of coal tar by-product were
also reduced. Our ability to obtain coal tar and the price we are able to negotiate have a significant impact on the level of profitability of our business. Most notably we have continued to see price increases in North America for coal tar due to
lower availability and the pricing terms in our purchasing contracts. Many of our sales contracts include provisions that allow for price increases based on increases in the price of raw materials, which has allowed us to generally maintain profit
dollars in our core businesses. However, significant increases in raw material costs will result in margin dilution because only the increased cost of the raw material is passed on to the customer.

The North American railroad market has experienced better stability than our other end markets in recent months; however, continued negative economic trends could impact the demand
for crossties from the short line railroads as well as the Class 1 railroads. Additionally, lumber availability and pricing were negatively impacted in 2008 by weather conditions as well as the depressed markets for furniture and hardwood flooring
caused by the dramatic decline in the U.S. housing market. While weather conditions are difficult to predict, it is likely that housing will remain depressed during 2009 and may result in continued difficulties related to cost and availability for
crossties.

Net sales over the past several years have been significantly impacted by favorable foreign exchange rates in Australia, Great Britain, Europe, Denmark
and China. In late 2008 and continuing into 2009 we saw those trends begin to reverse. Exchange rates for currencies in Australia, Great Britain, Europe, Denmark, and to a lesser extent, China, have changed significantly and will negatively impact
sales and profits in 2009 compared to 2008. In addition, we expect continued volatility in these exchange rates that could impact our ability to accurately predict future levels of sales and profits.

Seasonality and Effects of Weather on Operations

Our quarterly operating results
fluctuate due to a variety of factors that are outside of our control, including inclement weather conditions, which in the past have affected operating results. Operations at several facilities have been halted for short periods of time during the
winter months. Moreover, demand for some of our products declines during periods of inclement weather. As a result of the foregoing, we anticipate that we may experience material fluctuations in quarterly operating results. Historically, our
operating results have been significantly lower in the fourth and first calendar quarters as compared to the second and third calendar quarters. We expect this seasonality trend to continue in future periods.

Carbon materials
prices increased in the U.S. and China as customer prices were increased in response to substantially higher raw material costs. An increase in carbon materials sales volume was realized primarily in Australia and Europe totaling three percent and
was partially offset by decreases in China of one percent.

Distillate pricing improved due to price increases in carbon black feedstock prices in Europe and creosote
prices in the U.S. totaling three percent. The increase in carbon black feedstock pricing is consistent with higher average worldwide oil prices during the year. The increase in distillate sales volume is due primarily to increased creosote sales in
the U.S. totaling one percent.

For coal tar chemicals, increases in phthalic anhydride prices of one percent were partially offset by lower naphthalene prices in
Europe. The decrease in coal tar chemicals volumes is due primarily to lower phthalic anhydride volumes of one percent. With respect to other products, carbon black volumes, freight, specialty chemicals and other carbon products increased five
percent as compared to the prior year and were partially offset by lower commercial roofing sales. Carbon black prices experienced an increase of one percent as compared to the prior year.

In the fourth quarter of 2008, we began to experience negative pricing and volume trends due to lower commodity prices and global economic issues for most of the products listed
above. We expect these trends to impact sales volumes and margins into 2009.

R&UP net salesdecreased by $6.7 million or one percent due to the following
changes in volume and pricing:

|(a) | Includes treated and untreated railroad crossties.

|(b) | Includes sales from treatment services only (TSO).
|--- | ----------------------------------------------------

|(c) | Includes transmission poles, pilings, creosote, freight and other treated and untreated lumber products.
|--- | --------------------------------------------------------------------------------------------------------

Sales were negatively impacted by volume decreases of untreated railroad crossties totaling four percent for the year ended December 31, 2008 due to capital purchasing reductions by the Class 1 railroads and reduced raw
material availability due to weather and a weak timber market. Treated railroad crossties pricing increased by one percent for the year ended December 31, 2008 as raw material price increases were passed on to customers. The price increase in
other products is due primarily to higher creosote prices and transmission pole prices totaling two percent. The lower volumes in other products is due primarily to lower sales of untreated lumber products.

Cost of sales as a percentage of net sales was 84 percent for the year ended December 31, 2008 as compared to 82 percent for the year ended December 31, 2007.
Overall, cost of sales increased by $111.1 million when compared to the prior year period due primarily to higher raw material costs.

Depreciation and
amortization for the year ended December 31, 2008 was $0.5 million higher when compared to the prior year period and included an impairment charge of $3.7 million related to our glycerine refining plant in the United Kingdom.

Selling, general and administrative expenses for the year ended December 31, 2008 were $7.3 million lower when compared to the prior year period due primarily to due
diligence costs of $6.8 million incurred in 2007 related to a potential acquisition which was not consummated.

Interest expense for the year ended
December 31, 2008 was $6.7 million lower when compared to the prior year period due primarily to lower average borrowings on revolving credit facilities and term debt. Lower average borrowings resulted from debt reductions funded by cash flows
from operations and the net proceeds from the sale of Monessen in October 2008.

Income taxes for the year ended December 31, 2008 were $13.2 million
higher when compared to the prior year period due primarily to the increase in pretax income of $12.4 million and estimated taxes on unremitted European earnings for 2008. For the year ended December 31, 2007, all European earnings were
considered to be permanently reinvested and did not attract U.S. taxation. Our effective income tax rate for the year ended December 31, 2008 was 44.2 percent as compared to the prior year period of 36.2 percent. The increase in the effective
tax rate is due primarily to the U.S. taxation of European earnings in 2008.

Gain on sale of Monessenfor the year ended December 31, 2008 represents the
gain, net of tax expense, from the sale of our 95 percent interest in Monessen to ArcelorMittal S.A. on October 1, 2008. Effective as of this date, Monessen was classified as a discontinued operation in our statement of operations.

North American CM&C sales increased by $40.8 million due primarily to higher prices for carbon pitch, creosote and
phthalic anhydride totaling $43.0 million and higher volumes of creosote and refined tar totaling $10.4 million. Lower volumes of phthalic anhydride of $10.9 million partially offset these increases. Operating profit as a percentage of net sales
increased to 14.1 percent from 12.2 percent for the prior period.

European CM&C sales increased by $33.1 million due primarily to higher volumes of carbon
pitch, benzole and specialty chemicals totaling $14.2 million and higher prices for carbon black feedstock and benzole totaling $18.0 million. Operating profit as a percentage of net sales increased to 9.9 percent from 6.7 percent as a result of
higher carbon pitch volumes and higher pricing for carbon black feedstock as a result of higher average petroleum prices.

Australian CM&C sales increased
by $34.8 million due primarily to higher volumes for carbon pitch and carbon black which totaled $18.2 million. The increase in volume for carbon black is a result of the plant expansion project at the Companys carbon black plant becoming
fully operational. Increases in carbon black prices contributed higher sales of $11.2 million. Operating profit as a percentage of net sales was 15.6 percent for the as compared to 14.2 percent for the prior period.

Chinese CM&C sales increased by $7.5 million due primarily to higher volumes of carbon pitch and other products, principally distillates, totaling $10.9 million,
partially offset by lower carbon pitch volumes of $5.5 million. Currency exchange rate changes contributed $6.3 million to increased sales. Operating profit as a percentage of net sales was breakeven as compared to 9.5 percent for the prior period.
The decrease in operating margin is due primarily to inventory lower of cost of market writedowns and investment in sales and administrative functions in China.

CM&C operating profit margins for all geographical regions have trended downward in the fourth quarter of 2008 as the impact of the global economic recession reduced margins. This trend is expected to continue into 2009.

Railroad & Utility Products operating profit for the twelve months ended December 31, 2008 decreased by $18.8 million as compared to the prior
period primarily as a result of lower sales of untreated railroad crossties and TSO crossties and lower operating profit margins. Operating profit as a percentage of net sales decreased to 5.1 percent from 8.9 percent between periods due to lower
production and procurement levels for railroad crossties and the increased operating costs due to a boiler outage at one of the Companys wood treatment plants and the unplanned outage of an electricity cogeneration unit at another of the
Companys wood treatment plants.

Carbon materials
prices increased in the U.S., Europe and Australasia as customer prices have been renegotiated in response to substantially higher raw material costs. The increase in carbon materials sales volume is due partially to the acquisition of certain
imported carbon pitch supply contracts from Reilly Industries Inc. (Reilly acquisition) in April 2006 in addition to acquired domestic sales contracts related to the Reilly acquisition. These acquired import and domestic contracts
resulted in a total sales volume increase for the year ended December 31, 2007 of four percent.

Overall, distillate pricing was flat for the year ended
December 31, 2007 as increases in creosote prices in the U.S. were largely responsible for the total price increase of one percent. The increase in distillate sales volume is due primarily to higher European carbon black feedstock sales and
higher U.S. creosote sales of two percent in total.

For coal tar chemicals, increases in worldwide naphthalene prices and U.S. phthalic anhydride prices resulted in
a sales increase totaling one percent. Volume increases from naphthalene sales contributed to an increase of two percent. Changes in foreign exchange rates between the U.S. dollar and Australian and European currencies resulted in higher sales of
six percent across all product lines.

R&UP net sales increased by $45.9 million or 11 percent due to the following changes in volume and pricing:

Koppers Inc.2008 Annual Report



Sales price increases of treated railroad crossties totaled two percent for the year ended December 31, 2007. Volume increases in treated railroad crossties of one percent were offset by volume decreases in untreated
railroad crossties of the same percentage. The price increase in other products is due primarily to higher creosote prices totaling four percent. Higher raw material costs contributed to the pricing increases realized in treated railroad crossties
and creosote.

Cost of sales as a percentage of net sales was 82 percent for the year ended December 31, 2007 as compared to 84 percent for the year ended
December 31, 2006. Overall, cost of sales increased by $155.5 million when compared to the prior year period due primarily to higher raw material volumes from the Reilly acquisition, higher raw material costs and foreign exchange.

Depreciation and amortization for the year ended December 31, 2007 was $0.1 million lower when compared to the prior year period.

Selling, general and administrative expenses for the year ended December 31, 2007 were $9.0 million higher when compared to the prior year period due primarily to due
diligence costs of $6.8 million related to a potential acquisition which was not consummated. Other increases related to management incentive programs, stock-based compensation programs, and investment in sales and administrative functions in China.
Partially offsetting this increase was a one-time expense totaling $3.0 million for the termination of the Saratoga Partners III, L.P. (Saratoga) advisory services contract recognized in the year ended December 31, 2006.

Interest expense for the year ended December 31, 2007 was $16.8 million lower when compared to the prior year
period due primarily to costs incurred in the year ended December 31, 2006 related to our initial public offering. The proceeds from the offering were used to redeem $101.7 million of the 97/8percent Senior Secured Notes due 2013 (the Senior Secured Notes) which resulted in expenses totaling $14.4 million for call premiums, bond consent fees and the
write-off of deferred financing costs.

Income taxes for the year ended December 31, 2007 were $20.4 million higher when compared to the prior
year period due primarily to the increase in pretax income of $63.6 million. Our effective income tax rate for the year ended December 31, 2007 was 36.2 percent as compared to the prior year period of 44.1 percent. The decrease in the
effective tax rate is due primarily to the smaller impact (in proportion to pretax book income) from foreign earnings and permanent items.

Gain on sale of Koppers
Archfor the year ended December 31, 2007 represents the gain, net of tax expense, from the sale of our 51 percent interest in Koppers Arch to Arch Chemicals on July 5, 2007. Effective as of this date, Koppers Arch was classified as a
discontinued operation in our statement of operations.

North American CM&C sales increased $73.9 million due primarily to improved prices for carbon pitch, refined tar
and creosote of $39.5 million. In addition, incremental volumes of carbon pitch, refined tar and creosote sales related to sales contracts assumed in the Reilly acquisition contributed increased sales of $23.0 million. Operating profit as a
percentage of net sales increased to 12.2 percent from 9.9 percent between periods reflecting an increase in pricing for carbon materials, creosote and phthalic anhydride due primarily to higher raw material costs and realized operating efficiencies
related to the Reilly acquisition. Operating profit for 2007 and 2006 includes charges of $6.8 million and $1.5 million related to due diligence fees and the termination fee for the Saratoga advisory services contract, respectively.

European CM&C sales increased $45.7 million due primarily to higher prices for naphthalene and carbon pitch totaling $14.2 million and higher volumes of naphthalene and
carbon black feedstock totaling $9.7 million. In addition, changes in foreign exchange rates contributed $17.5 million of increased sales. Operating profit as a percentage of net sales increased slightly to 6.7 percent from 5.9 percent between
periods.

Australian and Chinese CM&C sales increased a combined $36.6 million due primarily to higher prices for carbon pitch and naphthalene totaling
$9.2 million and higher volumes for carbon pitch, naphthalene and carbon black feedstock totaling $15.4 million. In addition, changes in foreign exchange rates contributed $17.1 million of increased sales. Combined operating profit as a percentage
of net sales increased to 12.6 percent from 10.5 percent between periods reflecting an increase in pricing for carbon pitch, naphthalene and carbon black feedstock due primarily to higher raw material costs.

Railroad & Utility Products operating profit for the year ended December 31, 2007 increased by $18.9 million as compared to the prior period. Operating profit
as a percentage of net sales increased to 8.9 percent from 5.5 percent between periods due to higher prices for treated railroad crossties, crosstie treatment services, distribution poles and creosote in addition to the mix impact of higher volumes
of treated railroad crossties. Operating profit was also negatively impacted for the year ended December 31, 2006 by R&UPs share of the Saratoga advisory services contract buyout expense of $1.5 million in addition to the loss on the
sale of our specialty trackwork business and other plant closure costs totaling $1.9 million.

Cash Flow

Net cash provided by operating activities was $51.9 million for the year ended December 31, 2008 as compared to net cash provided by operating activities of $65.7
million for the year ended December 31, 2007. Net cash provided by operating activities for 2008 includes income taxes paid in connection with the Monessen transaction of approximately $50.0 million. Excluding this amount, net cash flow from
operating activities increased by approximately $36 million between periods due to improved working capital and lower interest payments.

Koppers Inc.2008 Annual Report



Net cash provided by operating activities was $65.7 million for the year ended December 31, 2007 as compared to net cash provided by operating activities of $30.7 million for the year ended December 31, 2006. The cash
flow for the prior period included payments associated with the initial public offering totaling $14.2 million for call premiums on the Senior Secured Notes, bond consent fees and the buyout of the Saratoga advisory services contract in addition to
the payment of a legal settlement totaling $2.6 million. Excluding these amounts, net cash flow from operating activities increased by $18.2 million between periods due to improved net income partially offset by increased working capital
requirements.

Net cash provided by investing activities was $120.7 million for the year ended December 31, 2008 as compared to net cash used in investing
activities of $16.5 million for the year ended December 31, 2007. Net cash proceeds from divestitures and asset sales primarily represent the net cash proceeds from the sale of Monessen. Increased capital spending in 2008 primarily related to
our plant expansion in China and increased environmental improvement spending at our U.S. wood treating plants. Acquisition expenditures in 2008 of $2.9 million relate to capital contributions to Tangshan Koppers Kailuan Carbon Chemical Company
Limited, our 30 percent-owned coal tar distillation joint venture in China.

Net cash used in investing activities was $16.5 million for the year ended
December 31, 2007 as compared to $71.2 million for the year ended December 31, 2006 which included $45.1 million for the Reilly acquisition. Acquisition expenditures in 2007 of $4.1 million relate to deferred purchase price payments for
Lambson Speciality Chemicals Limited, which was acquired in 2006 and capital contributions to Tangshan Koppers Kailuan Carbon Chemical Company Limited, our 30 percent-owned coal tar distillation joint venture in China. Net cash proceeds from
divestitures and asset sales of $11.9 million in 2007 primarily represents the cash proceeds, net of cash transferred to the acquirer, of Koppers Arch.

Net cash
used in financing activities was $123.0 million for the year ended December 31, 2008 as compared to net cash used in financing activities of $58.3 million for the year ended December 31, 2007. Net repayments of debt totaled $83.3
million in the year ended December 31, 2008, as a result of higher cash provided from the sale of Monessen and from operating activities (after adjustment for the cash taxes paid on Monessen).

Net cash used by financing activities was $58.3 million for the year ended December 31, 2007 as compared to net cash provided by financing activities of $36.6 million for the
year ended December 31, 2006. The cash flow for the prior period included capital contributions by Koppers Holdings of $110.1 million partially offset by the redemption of the Senior Secured Notes of $101.7 million. Additionally, term loan
borrowings of $50.0 million under Koppers Inc.s senior secured credit facility were used to provide for the Reilly acquisition. Net repayments of debt totaled $44.8 million in the year ended December 31, 2007, as a result of higher cash
provided by operating activities and the proceeds from the sale of Koppers Arch.

Dividends paidwere $38.4 million in the year ended December 31, 2008 as
compared to dividends paid of $14.7 million for the year ended December 31, 2007. Dividends paid in the year ended December 31, 2008 primarily reflect a dividend paid to Koppers Holdings to repurchase common stock under its common stock
repurchase program.

On February 4, 2009, the board of directors of Koppers Inc declared a quarterly dividend of 22 cents per common share of Koppers
Holdings common stock, payable on April 1, 2009 to Koppers Holdings.

Liquidity and Capital Resources

Restrictions on Dividends to Koppers Holdings

Koppers Holdings, the parent company of Koppers Inc., depends on the dividends from the earnings of Koppers Inc. and its subsidiaries to generate the funds necessary to meet our financial obligations, including payments of
principal, interest and other amounts on the 97/8 percent Senior Discount
Notes due 2014 (the Senior Discount Notes). The terms of Koppers Inc.s revolving credit facility as well as the terms of the indenture governing the Senior Secured Notes significantly restrict Koppers Inc. from paying dividends and
otherwise transferring assets to Koppers Holdings. The amount of permitted dividends under both debt facilities is governed by a formula based on 50 percent of consolidated net income, among other things. Cash equity contributions from the sale of
Koppers Holdings common stock increase the amount available for dividends. At the time of the payment of the dividend, no event of default shall have occurred or be continuing under the indenture or the revolving credit facility.

Under the indenture relating to the Senior Secured Notes, Koppers Inc. must have an EBITDA (as defined in the indenture) to consolidated interest expense ratio of at least 2.0
to 1.0. Additionally, the revolving credit facility requires compliance with all

financial covenants and availability of at least $35.0 million and leverage ratio less than 2.0 times under the revolving credit
facility after giving effect to any proposed dividend. Significant reductions in net income, or increases to indebtedness affecting compliance with financial covenants or availability under the revolving credit facility would restrict Koppers
Inc.s ability to pay dividends. As of December 31, 2008, dividends available to be declared based on covenant restrictions under the Senior Secured Notes amounted to $124.8 million.

Liquidity

The Koppers Inc. revolving credit facility agreement, as amended and restated,
provides for a revolving credit facility of up to $300.0 million at variable rates. The revolving credit facility replaced the Senior Secured Revolving Credit Facility on October 31, 2008. Borrowings under the revolving credit facility are
secured by a first priority lien on substantially all of Koppers Inc.s assets, including the assets of certain significant subsidiaries. The credit facility contains certain covenants that limit capital expenditures by Koppers Inc. and
restrict its ability to incur additional indebtedness, create liens on its assets, enter into leases, pay dividends and make investments or acquisitions. In addition, such covenants give rise to events of default upon the failure by Koppers Inc. to
meet certain financial ratios.

As of December 31, 2008, the Company had $283.0 million of unused revolving credit availability for working capital purposes
after restrictions by various debt covenants and certain letter of credit commitments. As of December 31, 2008, $17.0 million of commitments were utilized by outstanding letters of credit.

The following table summarizes Koppers estimated liquidity as of December 31, 2008 (dollars in millions):

|                                                 |  |   |      

Our estimated liquidity was $116.2 million at December 31, 2007. The increase in estimated liquidity from that date is
due primarily to an increase in availability under the new revolving credit facility and the increase in cash as a result of the Monessen transaction.

Our need for
cash in the next twelve months relates primarily to contractual obligations which include debt service, purchase commitments and operating leases, as well as for working capital, capital maintenance programs and mandatory defined benefit plan
funding. We may also use cash to pursue potential strategic acquisitions. Capital expenditures in 2009, excluding acquisitions, are expected to total approximately $23 million. We believe that our cash flow from operations and available borrowings
under the revolving credit facility will be sufficient to fund our anticipated liquidity requirements for at least the next twelve months. In the event that the foregoing sources are not sufficient to fund our expenditures and service our
indebtedness, we would be required to raise additional funds.

Cash Flows from Discontinued Operations

The cash flows related to Monessen and Koppers Arch for the three years ended December 31, 2008 have not been restated in the consolidated statement of cash flows. Excluding
cash proceeds from the sales of Monessen and Koppers Arch, the net cash inflows (outflows) of discontinued operations totaled $0.7 million, $(1.9) million and $(0.4) million for the years ended December 31, 2008, 2007 and 2006, respectively.

With respect to the Monessen sale, in February 2009 the acquirer filed a notice of objection in connection with the determination of certain assumed liabilities and
has requested an adjustment to the purchase price of approximately $2.0 million. Based upon the nature of the objections cited by the acquirer, at this time, we do not believe that the purchase price should be adjusted by a material amount and
accordingly, we have not provided for any adjustment to the purchase price as of December 31, 2008.

In connection with the sale of our 51 percent interest in
Koppers Arch, we have provided an indemnity to the buyer for our share of liabilities, if any, arising from certain litigation and claims existing at July 5, 2007. Our financial exposure pursuant to this indemnity is capped at a monetary limit
and is subject to time limitations.

obligations as of December 31, 2008. The table is based upon available information and certain assumptions we believe to be reasonable.

expect to be able to hedge the purchases with sales at those future prices.

Pension and other employee benefit plan funding obligations (for
defined benefit plans) are not included in the table above. We expect defined benefit plan contributions to total approximately $3 million in 2009. Although asset values in our pension plan trusts declined significantly in 2008, under current law we
do not expect to be required to make mandatory contributions in 2009 to our U.S. qualified defined benefit plan, our largest defined benefit plan. However, without legislative relief, we estimate that mandatory funding for this plan will be
approximately $20 million in 2010 and $30 million in 2011. Estimated funding obligations are determined by asset performance, workforce and retiree demographics, tax and employment laws and other actuarial assumptions which may change the annual
funding obligations. The funded status of our defined benefit plans is disclosed in Note 16 of the Consolidated Financial Statements.

Schedule of Certain Other
Commercial Commitments

The following table details our projected payments for other significant commercial commitments as of December 31, 2008. The table is

Debt Covenants

The covenants that
affect availability of the revolving credit facility and which may restrict the ability of Koppers Inc. to pay dividends include the following financial ratios:



| | ¡ |  | The fixed charge coverage ratio, calculated as of the end of each fiscal quarter for the four fiscal quarters then ended, is not permitted to be less than 1.10. The fixed
charge coverage ratio at December 31, 2008 was 3.2.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ¡ |  | The leverage ratio, calculated as of the end of each fiscal quarter for the four fiscal quarters then ended, is not permitted to exceed 2.75. The leverage ratio at
December 31, 2008 was 0.84.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ¡ |  | The domestic interest coverage ratio, calculated as of the end of each fiscal quarter for the four fiscal quarters then ended, is not permitted to be less than 3.0. The
domestic interest coverage ratio at December 31, 2008 was 6.7.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We are currently in compliance with all covenants in the credit agreement
governing the revolving credit facility.

At December 31, 2008, Koppers Inc. had $185.9 million outstanding of Senior Secured Notes (excluding adjustment for a
related interest rate swap). The Senior Secured Notes include customary covenants that restrict, among other things, our ability

to incur additional debt, pay dividends or make certain other restricted payments, incur liens, merge or sell all or substantially
all of the assets or enter into various transactions with affiliates. We are currently in compliance with all covenants in the indentures governing the Senior Secured Notes.

Subsidiary Pledges

The terms of the Senior Secured Notes provide that the collateral securing the Senior Secured Notes will never include the
securities of any subsidiary to the extent the par value, book value as carried by us or the market value of the securities (the Applicable Value) is equal to or greater than 20 percent of the aggregate principal amount of the Senior
Secured Notes outstanding (the Collateral Threshold). Rule 3-16 of Regulation S-X under the Securities Act of 1933 requires the presentation of a subsidiarys stand-alone, audited financial statements if the subsidiarys
capital stock secures an issuers notes and the par value, book value or market value of the securities equals or exceeds the Collateral Threshold. The indenture governing the Senior Secured Notes and the security documents provide that the
collateral will never include the capital stock of any subsidiary to the extent the Applicable Value of the securities is equal to or greater than the Collateral Threshold. As a result, Koppers will not be required to present separate financial
statements of any of its subsidiaries under Rule 3-16.

As a result of the provisions in the indenture and security documents relating to subsidiary securities,
holders of the Senior Secured Notes may at any time in the future lose a portion of their security interest in the securities of any of our other subsidiaries if the Applicable Value of that stock were to become equal to or greater than the
Collateral Threshold. As stated above, Applicable Value is defined as the greatest of book value, par value and market value of a subsidiarys securities. Currently, all of the capital stock of all of our domestic subsidiaries other than
World-Wide Ventures Corp., Koppers Australia Holding Company Pty Ltd., Koppers Australia Pty Ltd., Koppers Delaware, Inc., and all of our subsidiaries other than 35 percent of the voting capital stock of Koppers Europe ApS constitute collateral for
the Senior Secured Notes.

We have based our determination of which subsidiarys capital stock currently constitutes collateral upon the book value, par value
and estimated market value of the capital stock of each of its subsidiaries as of December 31, 2008 and the operations of these subsidiaries since that date. The Applicable Value for the capital stock of each of our subsidiaries is the greater
of the book value and estimated market value, as the value of each subsidiarys capital stock is nominal and therefore has not impacted our calculation of Applicable Value. The Net Fair Value and Net Book Value calculations each include an
allocation of corporate debt to the subsidiaries. Set forth in the table below is the Applicable Value of each subsidiarys capital stock as of December 31, 2008:

Based upon the
foregoing, the Applicable Value of the capital stock of Worldwide Ventures Corp., Koppers Australia Holding Company Pty Ltd., Koppers Australia Pty Ltd., Koppers Delaware, Inc. and Koppers Europe ApS exceeded the Collateral Threshold of $43.7
million as of December 31, 2008. Further, we believe that, based upon the significant differences between the Applicable Value of the capital stock of Worldwide Ventures Corp., Koppers Australia Holding Company Pty Ltd., Koppers Australia Pty
Ltd., Koppers Delaware, Inc., Koppers Europe ApS and the Collateral Threshold as of December 31, 2008 (there

Koppers Inc.2008 Annual Report



have been no significant changes in the operations of Worldwide Ventures Corp., Koppers Australia Holding Company Pty Ltd., Koppers Australia Pty Ltd., Koppers
Delaware, Inc. and Koppers Europe ApS since that date), we have determined that the Applicable Value of the capital stock of Worldwide Ventures Corp., Koppers Australia Holding Company Pty Ltd., Koppers Australia Pty Ltd., Koppers Delaware, Inc. and
Koppers Europe ApS currently exceed the Collateral Threshold. As a result, the pledges of capital stock of Worldwide Ventures Corp., Koppers Australia Holding Company Pty Ltd., Koppers Australia Pty Ltd., Koppers Delaware, Inc. and Koppers Europe
ApS are automatically reduced to the extent that the Applicable Value exceeds the Collateral Threshold.

In respect of Koppers Assurance, Inc., Koppers Delaware,
Inc., Koppers Concrete Products, Inc. and Concrete Partners, Inc., the Applicable Value of their common stock was based upon book value. Book value of a subsidiarys capital stock is calculated as of each preceding period end and represents the
original purchase price of the subsidiarys capital stock plus any income earned less any losses and any transfers of assets.

In respect of World-Wide Ventures
Corp., Koppers Australia Holding Company Pty Ltd., Koppers Australia Pty Ltd. and Koppers Europe ApS, the Applicable Value of their common stock was based upon estimated market value. We have calculated the estimated market value of our
subsidiaries capital stock by determining the earnings before interest, taxes, depreciation and amortization, or EBITDA, of each subsidiary for the twelve months ended December 31, 2008, and multiplying this EBITDA by a multiple used by
Koppers Holdings for the initial public offering price in February 2006, based on the fact that the value of Koppers Holdings shares were based upon the performance of its wholly owned subsidiary, Koppers Inc. The Company determined that using
this multiple continues to be a reasonable and appropriate means for determining fair value of our subsidiaries capital stock.

As described above, we have used
EBITDA of each of our subsidiaries solely for purposes of determining the estimated market value of the capital stock to determine whether that capital stock is included in the collateral. EBITDA is not a recognized financial measure under U.S. GAAP
and does not purport to be an alternative to operating income as an indicator of operating performance or to cash flows from operating activities as a measure of liquidity. Additionally, EBITDA has limitations as an analytical tool and should not be
considered in isolation or as a substitute for analysis of our consolidated results as reported under U.S. GAAP. Because not all companies use identical calculations, the presentation of EBITDA also may not be comparable to other similarly titled
measures of other companies. An evaluation should be made of the adjustments and the reasons we consider them appropriate for analysis for determining estimated market value of the capital stock of our subsidiaries.

A change in the Applicable Value of the capital stock of any of our subsidiaries could result in a subsidiarys capital stock that was previously excluded from collateral
becoming part of the collateral or a subsidiarys capital stock that was previously included in collateral being excluded. The following table reflects the amount by which the Applicable Value of each subsidiarys capital stock as of
December 31, 2008 would have to change in order for a portion of that subsidiarys capital stock to no longer constitute collateral or, in the case of World-Wide Ventures Corp., Koppers Australia Holding Company Pty. Ltd., Koppers
Australia Pty Ltd., Koppers Delaware, Inc., and Koppers Europe ApS would have to decrease in order for the capital stock of each of World-Wide Ventures Corp., Koppers Australia Holding Company Pty Ltd., Koppers Australia Pty Ltd., Koppers Delaware,
Inc., and Koppers Europe ApS that is currently not collateral to become collateral:

Other Matters

Interest Rate Swap

In January 2004, Koppers Inc. entered into an interest rate swap agreement for $50.0 million of the Senior Secured Notes in order to protect a portion of the debt against changes in fair value due to changes in the benchmark interest rate.
The agreement is designed to receive fixed 97/8percent and pay floating six-month LIBOR rates plus a spread of 5.395 percent with semiannual settlements through October 2013. Changes in
the fair value of the interest rate swap are expected to offset changes in the fair value of the Senior Secured Notes. The impact on the years ended December 31, 2008, 2007 and 2006 was to increase (decrease) interest expense by $(0.3) million,
$0.5 million and $0.3 million, respectively. The fair value of the swap agreement at December 31, 2008 was an asset of approximately $1.9 million.

Foreign Operations and Foreign Currency Transactions

We are subject to foreign currency translation fluctuations due to our foreign operations. For
the years ended December 31, 2008, 2007 and 2006, exchange rate fluctuations resulted in an increase (decrease) to comprehensive income of $(29.1) million, $11.0 million and $10.3 million, respectively. Foreign currency transaction gains
and losses result from transactions denominated in a currency which is different from the currency used by the entity to prepare its financial statements. Foreign currency transaction gains (losses) were $1.8 million, $0.4 million and $(0.8)
million for the years ended December 31, 2008, 2007 and 2006, respectively.

Recently Issued Accounting Guidance

The information related to recently-issued accounting guidance set forth in Note 3 to the consolidated financial statements is hereby incorporated by reference.

Critical Accounting Policies

The preparation of financial statements in conformity with
generally accepted accounting principles in the United States requires management to use judgment in making estimates and assumptions that affect the reported amounts of revenues and expenses, assets and liabilities, and the disclosure of contingent
liabilities. The following accounting policies are based on, among other things, judgments and assumptions made by management that include inherent risks and uncertainties. Our managements estimates are based on the relevant information
available at the end of each period.

Revenue Recognition. We recognize revenue from product sales at the time of shipment or when title passes to
the customer. We recognize revenue related to the procurement of certain untreated railroad crossties upon transfer of title, which occurs upon delivery to our plant and acceptance by the customer. Service revenue, consisting primarily of wood
treating services, is recognized at the time the service is provided. Our recognition of revenue with respect to untreated crossties meets all the recognition criteria of the Securities and Exchange Commissions Staff Accounting Bulletin Topic
13A3, including transfer of title and risk of ownership, the existence of fixed purchase commitments and delivery schedules established by the customer and the completion of all performance obligations by us.

Accounts Receivable. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments.
In circumstances where we become aware of a specific customers inability to meet its financial obligations, a specific reserve for bad debts is recorded against amounts due. If the financial conditions of our customers were to deteriorate,
resulting in an impairment of their ability to make payments, additional allowances may be required.

Inventories. In the United States, CM&C
and R&UP inventories are valued at the lower of cost, utilizing the last-in, first-out (LIFO) basis, or market. Inventories outside the United States are valued at the lower of cost, utilizing the first-in, first-out basis
(FIFO), or market. Market represents replacement cost for raw materials and net realizable value for work in process and finished goods. LIFO inventories constituted approximately 63 percent and 53 percent of the FIFO inventory value at
December 31, 2008 and 2007, respectively.

Long-Lived Assets. Our management periodically evaluates the net realizable value of long-lived
assets, including property, plant and equipment, based on a number of factors including operating results, projected future cash flows and business plans.

##### Table of Contents

Koppers Inc.2008 Annual Report



We record long-lived assets at the lower of cost or fair value, with fair value based on assumptions concerning the amount and timing of estimated future cash flows.
Since judgment is involved in determining the fair value of fixed assets, there is a risk that the carrying value of our long-lived assets may be overstated.

Goodwill. Goodwill is not amortized but is assessed for impairment at least on an annual basis. In making this assessment, management relies on various factors, including operating results, estimated future cash flows,
and business plans. There are inherent uncertainties related to these factors and in our managements judgment in applying them to the analysis of goodwill impairment. Because managements judgment is involved in performing goodwill
impairment analyses, there is risk that the carrying value of goodwill is overstated.

Goodwill valuations are performed using an average of actual and projected
operating results of the relevant reporting units. Changes in economic and operating conditions impacting these assumptions could result in goodwill impairments in future periods. Additionally, disruptions to our business such as prolonged
recessionary periods or unexpected significant declines in operating results of the relevant reporting units could result in charges for goodwill and other asset impairments in future periods.

Deferred Tax Assets. At December 31, 2008 our balance sheet included $62.3 million of deferred tax assets. We have determined that a valuation allowance of
$4.2 million is required for these deferred tax assets, based on future earnings projections. To the extent that we encounter unexpected difficulties in market conditions, adverse changes in regulations affecting our businesses and operations,
adverse outcomes in legal and environmental matters, or any other unfavorable conditions, the projections for future taxable income may be overstated and we may be required to record an increase in the valuation allowance related to these deferred
tax assets which could have a material adverse effect on income in the future.

Accrued Insurance. We are insured for property, casualty and
workers compensation insurance up to various stop loss amounts after meeting required retention levels. Losses are accrued based upon estimates of the liability for the related retentions for claims incurred using certain actuarial assumptions
followed in the insurance industry and based on our experience. In the event we incur a significant number of losses beyond the coverage retention limits, additional expense beyond the actuarial projections would be required.

Asset Retirement Obligations. We measure asset retirement obligations based upon the applicable accounting guidance, using certain assumptions including
estimates regarding the recovery of residues in storage tanks. In the event that operational or regulatory issues vary from our estimates, we could incur additional significant charges to income and increases in cash expenditures related to the
disposal of those residues.

Pension and Postretirement Benefits. Accounting for pensions and other postretirement benefits involves estimating the
cost of benefits to be provided far into the future and allocating that cost over the time period each employee works. This calculation requires extensive use of assumptions regarding inflation, investment returns, mortality, medical costs, employee
turnover and discount rates. In determining the expected return on plan assets assumptions, we evaluate long-term actual return information, the mix of investments that comprise plan assets and estimates of future investment returns. In selecting
rates for current and long-term health care assumptions, we take into consideration a number of factors including our actual health care cost increases, the design of our benefit programs, the characteristics of our active and retiree populations
and expectations of inflation rates. Because these items require our managements judgment, the related liabilities currently recorded by us could be lower or higher than amounts ultimately required to be paid.

Litigation & Contingencies. We record liabilities related to legal matters when an adverse outcome is probable and reasonably estimable. To the
extent we anticipate favorable outcomes to these matters which ultimately result in adverse outcomes, we could incur material adverse impacts on earnings and cash flows. Because such matters require significant judgments on the part of management,
the recorded liabilities could be lower than what is ultimately required.

Environmental Liabilities. We are subject to federal, state,
local and foreign laws and regulations and potential liabilities relating to the protection of the environment and human health and safety, including, among other things, the cleanup of contaminated sites, the treatment, storage and disposal of
wastes, the discharge of effluent into waterways, the emission of substances into the air and various health and safety matters. We expect to incur substantial costs for ongoing compliance with such laws and regulations. We may also incur costs as a
result of governmental or third-party claims, or otherwise incur costs, relating to cleanup of, or for injuries resulting from, contamination at sites associated with past and present operations. We accrue for environmental liabilities when a
determination can be made that they are probable and reasonably estimable.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Like other global companies, we are exposed
to market risks relating to fluctuations in interest rates and foreign currency exchange rates. The objective of our financial risk management is to minimize the negative impact of interest rate and foreign exchange rate fluctuations on our
earnings, cash flows and equity.

To manage the interest rate risks, we use a combination of fixed and variable rate debt. This reduces the impact of short-term
fluctuations in interest rates. To manage foreign currency exchange rate risks, we enter into foreign currency debt instruments that are held by our foreign subsidiaries. This reduces the impact of fluctuating currencies on net income and equity. We
also use forward exchange contracts to hedge firm commitments up to twelve months and all such contracts are marked to market with the recognition of a gain or loss at each reporting period.

The following analyses present the sensitivity of the market value, earnings and cash flows of our financial instruments and foreign operations to hypothetical changes in interest
and exchange rates as if these changes occurred at December 31, 2008 and 2007. The range of changes chosen for these analyses reflects our view of changes which are reasonably possible over a one-year period. Market values are the present
values of projected future cash flows based on the interest rate and exchange rate assumptions. These forward-looking statements are selective in nature and only address the potential impacts from financial instruments and foreign operations. They
do not include other potential effects that could impact our business as a result of these changes.

Interest Rate and Debt Sensitivity
Analysis. Our exposure to market risk for changes in interest rates relates primarily to our debt obligations. We have both fixed and variable rate debt to manage interest rate risk and to minimize borrowing costs. In January 2004, we
also entered into an interest rate swap arrangement with respect to notional $50.0 million of the Senior Secured Notes. (See Managements Discussion and Analysis of Financial Condition and Results of Operations  Liquidity and
Capital Resources.) The fair market value of the interest rate swap was an asset of $1.9 million at December 31, 2008.

At December 31, 2008 we had
$136.4 million of fixed rate debt and $50.0 million of variable rate debt, and at December 31, 2007, we had $168.4 million of fixed rate debt and $102.9 million of variable rate debt (for both years, including the swap). Our ratio of variable
rate debt to fixed rate debt at December 31, 2008, including the interest rate swap referred to above, was approximately 28 percent, reflecting a decrease in the ratio from 38 percent in the previous period due to the decrease in variable rate
borrowings under our senior secured credit facility. For fixed rate debt, interest rate changes affect the fair market value but do not impact earnings or cash flows. For variable rate debt, interest rate changes generally do not affect the fair
market value but do impact future earnings and cash flows, assuming other factors are held constant.

Holding other variables constant (such as debt levels and
foreign exchange rates), a one percentage point decrease in interest rates at December 31, 2008 and 2007 would have increased the unrealized fair market value of the fixed rate debt by approximately $8.1 million and $10.1 million, respectively.
The earnings and cash flows for the next year assuming a one percentage point increase in interest rates would decrease approximately $0.5 million, holding other variables constant. With respect to the interest rate swap, a ten percent decrease in
interest rates at December 31, 2008 would have increased the unrealized fair market value of the interest rate swap by approximately $0.2 million to an asset of $2.1 million. A ten percent increase in interest rates at December 31, 2008
would have decreased the unrealized fair market value of the interest rate swap by approximately $0.2 million to an asset of $1.7 million.

Exchange Rate
Sensitivity Analysis. Our exchange rate exposures result primarily from our investment and ongoing operations in Australia, Denmark and the United Kingdom. Holding other variables constant, if there were a ten percent reduction in all
relevant exchange rates, the effect on our earnings, based on actual earnings from foreign operations for the years ended December 31, 2008 and 2007, would be reductions of approximately $3.7 million and $2.5 million, respectively.

MANAGEMENTS REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Koppers Inc. is responsible for establishing and maintaining adequate internal control over financial reporting. 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 reporting purposes in accordance with accounting principles generally accepted in the United
States of America.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Management has assessed
the effectiveness of Koppers Inc.s internal control over financial reporting as of December 31, 2008. In making this assessment, management has utilized the criteria set forth by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO) in Internal Control-Integrated Framework. Management concluded that based on its assessment, Koppers Inc.s internal control over financial reporting was effective as of December 31, 2008.

This annual report does not include an attestation report of Koppers Inc.s registered public accounting firm regarding internal control over financial reporting.
Managements report was not subject to attestation by Koppers Inc.s registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit Koppers Inc. to provide only managements report
in this annual report.

Koppers Inc.2008 Annual Report



REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholder of Koppers Inc.:

We have audited the accompanying consolidated balance sheets of Koppers Inc. and subsidiaries as of December 31, 2008 and 2007, and the related consolidated
statements of operations, comprehensive income, stockholders equity, and cash flows for each of the three years in the period ended December 31, 2008. Our audits also included the financial statement schedule listed in the Index at
Item 15(a). These financial statements and schedule are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements and schedule 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. We were not engaged to perform an audit of the Companys internal control over financial reporting. Our audits included consideration
of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purposes of expressing an opinion on the effectiveness of the Companys internal control over
financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant
estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In
our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Koppers Inc. and subsidiaries at December 31, 2008 and 2007, and the consolidated results of
their operations and their cash flows for each of the three years in the period ended December 31, 2008, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when
considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects, the information set forth therein.

As discussed
in Note 16 to the consolidated financial statements, effective December 31, 2006, Koppers Inc. and subsidiaries adopted the funded status recognition provisions of Statement of Financial Accounting Standards No. 158, Employers
Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87,88,106 and 132(R).As discussed in Notes 8 and 16, respectively, to the consolidated financial statements, effective
January 1, 2007, Koppers Inc. and subsidiaries adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109 and the measurement date provisions of Statement of
Financial Accounting Standards No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87,88,106 and 132(R).

KOPPERS INC.

NOTES TO
CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business

Business
description  Koppers Inc. (the Company) is a global integrated producer of carbon compounds and treated wood products for use in a variety of markets including the aluminum, railroad, specialty chemical, utility, rubber, and
steel industries. The Companys business is managed as two business segments, Carbon Materials & Chemicals and Railroad & Utility Products.

The Companys Carbon Materials & Chemicals segment is primarily a supplier of carbon pitch, phthalic anhydride, creosote, carbon black and carbon black feedstock. Carbon pitch is used primarily by the aluminum industry as a
binder in the manufacture of anodes. Phthalic anhydride is used in the manufacture of plasticizers, unsaturated polyester resins, alkyd resins and dye making. Creosote is used in the protection of timber products against insects, fungal decay and
weathering. Carbon black and carbon black feedstock are used in the production of rubber tires.

The Companys Railroad & Utility Products segment
provides various products and services to railroads, including crossties (both wood and concrete), track panels and switch pre-assemblies and disposal services. The segment also supplies treated wood poles to electric and telephone utilities and
provides products to, and performs various wood treating services for construction and other commercial applications.

Wholly-owned subsidiary of Koppers Holdings
Inc. Koppers Holdings Inc., formerly known as KI Holdings Inc., was incorporated on November 12, 2004. On November 18, 2004, all of the common and preferred stock of Koppers Inc. was converted into shares of common and preferred
stock of Koppers Holdings Inc. (Koppers Holdings). Koppers Holdings and Koppers Inc. are separate and distinct legal entities. Koppers Holdings has no direct operations and no significant assets other than the stock of Koppers Inc. as of
December 31, 2008. It depends on the dividends from the earnings of Koppers Inc. and its subsidiaries to generate the funds necessary to meet its financial obligations, including payments of principal, interest, and other amounts on the Koppers
Holdings Senior Discount Notes due 2014. The terms of Koppers Inc.s revolving credit facility prohibit Koppers Inc. from paying dividends and otherwise transferring assets except for certain limited dividends. Further, the terms of the
indenture governing the Koppers Inc.s Senior Secured Notes significantly restrict Koppers Inc. from paying dividends and otherwise transferring assets to Koppers Holdings.

Initial public offering of Koppers Holdings  Koppers Holdings completed an initial public offering (IPO) on February 6, 2006, resulting in the issuance of 8,700,000 additional common shares at a
price of $14.00 per share, and the conversion of 2,288,481 shares of preferred stock into 9,107,926 shares of common stock. Of such converted shares, 2,800,000 were sold by the Koppers Holdings shareholders in connection with the IPO and the related
over-allotment option. Koppers Holdings received approximately $111.1 million of net proceeds (after $10.7 million of expenses) from the issuance and sale of 8,700,000 shares, which proceeds were used to redeem $101.7 million principal amount of the
Senior Secured Notes due 2013 (the Senior Secured Notes) and pay a related call premium of $10.1 million. The Company wrote off $3.2 million of deferred financing costs related to the buyback of the notes and incurred $1.1 million of
bond consent fees. The call premium, write-off of deferred financing costs, and consent fees were recorded as interest expense. The Company also incurred $3.0 million for the termination of the Saratoga Partners III, L.P. (Saratoga)
advisory services contract, which was recorded in selling, general and administrative expense. A post-IPO dividend to Koppers Holdings of $7.0 million, the consent fees and the Saratoga termination fee were financed through borrowings under the
senior secured credit agreement.

2. Summary of Significant Accounting Policies

Principles of consolidation  The consolidated financial statements include the accounts of the Company and all majority-owned subsidiaries for which the Company is deemed to exercise control over its operations. All significant
intercompany transactions have been eliminated. The Companys investments in 20 percent to 50 percent-owned companies in which it has the ability to exercise significant influence over operating and financial policies are accounted for using
the equity method of accounting. Accordingly, the Companys share of the earnings of these companies is included in the accompanying consolidated statement of operations.

Use of estimates  Accounting principles generally accepted in the U.S. require management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of
contingencies on the date of the financial



46

Koppers Inc.2008 Annual Report



statements as well as the reported amounts of revenues and expenses during the reporting period. Estimates have been prepared on the basis of the most current and best
available information and actual results could differ materially from these estimates.

Foreign currency translation  For consolidated entities outside
of the U.S. that prepare financial statements in currencies other than the U.S. dollar, results of operations and cash flows are translated at average exchange rates during the period, and asset and liabilities are generally translated at
end-of-period exchange rates. Cumulative translation adjustments are included as a separate component of accumulated other comprehensive income (loss) in stockholders equity. Currency translation gains released to income totaled $2.8 million
for the year ended December 31, 2007 and related to the sale of Koppers Arch Investments Pty Limited and its subsidiaries.

Foreign currency transaction gains
and losses result from transactions denominated in a currency which is different than the currency used by the entity to prepare its financial statements. Foreign currency transaction gains (losses) were $1.8 million, $0.4 million and $(0.8) million
for the years ended December 31, 2008, 2007 and 2006, respectively.

Revenue recognition The Company recognizes revenue when the risks and rewards
of ownership and title to the product have transferred to the customer. Revenue recognition generally occurs at the point of shipment; however in certain circumstances as shipping terms dictate, revenue is recognized at the point of destination.
Shipping and handling costs are included as a component of cost of sales.

The Company recognizes revenue related to the procurement of certain untreated railroad
crossties upon transfer of title to the customer, which occurs upon delivery to the Companys plant and acceptance by the customer. Service revenue, consisting primarily of wood treating services, is recognized at the time the service is
provided. Payment on sales of untreated railroad crossties and wood treating services are generally due within 30 days of the invoice date. The Companys recognition of revenue with respect to untreated crossties meets all the recognition
criteria of SEC Staff Accounting Bulletin Topic 13.A.3., including transfer of title and risk of ownership, the existence of fixed purchase commitments and delivery schedules established by the customer, and the completion of all performance
obligations by the Company. Revenue recognized for untreated crosstie sales for the years ended December 31, 2008, 2007 and 2006 amounted to $98.9 million, $111.1 million and $113.0 million, respectively.

Research & development Research and development costs are expensed as incurred and are included in selling, general and administrative expenses. These costs
totaled $2.8 million in 2008, $2.8 million in 2007 and $2.5 million in 2006.

Cash and cash equivalents  Cash and cash equivalents include cash on hand
and on deposit and investments in highly liquid investments with an original maturity of 90 days or less.

Restricted cash  Restricted cash includes cash
that is required to be held on deposit by a bank and is not available for immediate withdrawal.

Accounts receivable The Company maintains allowances
for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. In circumstances where the Company becomes aware of a specific customers inability to meet its financial obligations to
Koppers, a specific reserve for bad debts is recorded against amounts due. If the financial condition of the Companys customers were to deteriorate, resulting in an inability to make payments, additional allowances may be required. The
allowance for doubtful accounts was $0.5 million and $0.2 million as of December 31, 2008 and 2007, respectively.

Inventories Inventories are
carried at lower of cost or market on a worldwide basis. In the U.S., inventory cost (excluding miscellaneous types of inventory) is determined primarily utilizing the last-in, first-out (LIFO) basis. Inventory cost outside the U.S. is
determined utilizing the first-in, first-out (FIFO) basis. Market represents replacement cost for raw materials and net realizable value for work in process and finished goods. LIFO inventories constituted approximately 63 percent and 53
percent of the FIFO inventory value at December 31, 2008 and 2007, respectively.

Property, plant & equipment Property, plant and
equipment are recorded at purchased cost and include improvements which significantly increase capacities or extend useful lives of existing plant and equipment. Depreciation expense is calculated by applying the straight-line method over estimated
useful lives. Estimated useful lives for buildings generally range from 10 to 20 years and depreciable lives for machinery and equipment generally range from 3 to 10 years. Net gains and losses related to asset disposals are recognized in earnings
in the period in which the disposal occurs. Routine repairs, replacements and maintenance are expensed as incurred.

The Company
periodically evaluates whether current facts and circumstances indicate that the carrying value of its depreciable long-lived assets may not be recoverable. If an asset, or logical grouping of assets, is determined to be impaired, the asset is
written down to its fair value using discounted future cash flows and, if available, quoted market prices.

Goodwill & other intangible assets Goodwill and other purchased intangible assets are included in the identifiable assets of the business segment to which they have been assigned. The Company performs impairment tests annually for goodwill, and more often as circumstances
require. When it is determined that impairment has occurred, an appropriate charge to earnings is recorded. The Company performed its annual impairment test in the fourth quarters of 2008 and 2007 and determined there was no impairment of goodwill.

Identifiable intangible assets, other than goodwill, are recorded at cost. Identifiable intangible assets that do not have indefinite lives are amortized on a
straight-line basis over their estimated useful lives.

Deferred income taxes  Deferred tax assets and liabilities are recognized for future tax
consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The effect on deferred tax assets and liabilities of a change in tax laws is recognized in
earnings in the period the new laws are enacted. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely than not that such assets will be realized. Deferred tax liabilities have not been
recognized for the undistributed earnings of certain foreign subsidiaries because management intends to permanently reinvest such earnings in foreign operations.

Insurance The Company is self-insured for property, casualty and workers compensation exposures up to various stop-loss coverage amounts. Losses are accrued based upon the Companys estimates of the liability for
the related deductibles of claims incurred. Such estimates utilize actuarial methods based on various assumptions, which include but are not limited to, the Companys historical loss experience and projected loss development factors. In 2008
and 2007, the Company reversed $2.0 million and $1.7 million, respectively, of insurance loss reserves as a result of favorable loss trends related to self-insured claims. Such reversals increased operating profit in both periods. Insurance loss
reserves accrued at December 31, 2008 and 2007 totaled $11.9 million at both dates.

Derivative financial instruments The Company uses forward
exchange contracts to hedge exposure to currency exchange rate changes on transactions and other commitments denominated in a foreign currency. Contracts are generally written on a short-term basis and are not held for trading or speculative
purposes. The Company recognizes the fair value of the forward contracts as an asset or liability at each reporting date. Because the Company has not elected to designate the forward exchange contracts for hedge accounting treatment, changes in the
fair value of the forward exchange contracts are recognized immediately in earnings.

During 2004, the Company entered into an interest rate swap agreement to convert
the fixed rate on a portion ($50.0 million) of the Senior Secured Notes to a floating rate based on six-month LIBOR rates plus a specified spread. The swap agreement matures in October 2013 and requires semiannual cash settlements of interest paid
or received. The differential between the interest paid or interest received from semi-annual settlements are recorded as an adjustment to interest expense. The effect of the swap for the year ended December 31, 2008 was a decrease in interest
expense of approximately $0.3 million and for the years ended December 31, 2007 and 2006 was an increase in interest expense of approximately $0.5 million and $0.3 million, respectively. The swap hedges the Companys exposure related to
changes in interest rates on the fair value of the Companys fixed rate debt. The swap is accounted for as a fair value hedge and has been determined to have no ineffectiveness as the critical terms of the swap are aligned with the hedged item.
Any changes in the fair value of the swap are offset by an equal and opposite change in the fair value of the hedged item, therefore there is no net impact on reported earnings. Accordingly, the principal amount of the Senior Secured Notes subject
to the interest rate swap is adjusted to fair value. The fair value of the swap agreement at December 31, 2008 was an asset of $1.9 million which is recorded in other assets in the balance sheet. The fair value of the swap agreement at
December 31, 2007 was a liability of $0.5 million which is recorded in other long-term liabilities in the balance sheet.

Asset retirement obligations
 Asset retirement obligations are initially recorded at fair value and are capitalized as part of the cost of the related long-lived asset when sufficient information is available to estimate fair value. The capitalized costs are
subsequently charged to depreciation expense over the estimated useful life of the related long-lived asset. The fair value of the obligation is determined by calculating the discounted value of expected future cash flows and accretion expense is
recorded each month to ultimately increase this obligation to full value.

Koppers Inc.2008 Annual Report



The Company recognizes asset retirement obligations for the removal and disposal of residues; dismantling of certain tanks required by governmental authorities; cleaning and dismantling costs for owned rail cars; and
cleaning costs for leased rail cars and barges.

Litigation & contingencies  Amounts associated with litigation and contingencies are accrued
when management, after taking into consideration the facts and circumstances of each matter including any settlement offers, has determined that it is probable that a liability has been incurred and the amount of loss can be reasonably estimated.

Environmental liabilities The Company accrues for remediation costs and penalties when the responsibility to remediate is probable and the amount of
related cost is reasonably estimable. If only a range of potential liability can be estimated and no amount within the range is more probable than another, the accrual is recorded at the low end of that range. Remediation liabilities are discounted
if the amount and timing of the cash disbursements are readily determinable.

Deferred revenue from extended product warranty liabilities The Company
defers revenues associated with extended product warranty liabilities based on historical loss experience and sales of extended warranties on certain products. The following table describes changes to the Companys deferred revenue at
December 31, 2008 and 2007:



|                                                                 |  |      |      |   |      |   |      |

Stock-based compensation Koppers Holdings Inc, the parent company of Koppers Inc. has sponsored various
stock-based employee compensation plans which are described more fully in Note 7. Employees of Koppers Inc. participate in these plans and receive common stock of Koppers Holdings Inc. The Company records compensation cost over the vesting
period for share-based payments to employees at an amount equivalent to the grant date fair value of the stock award. No compensation cost is recognized for any stock awards that are forfeited in the event the recipient fails to meet the vesting
requirements.

Reclassifications Certain amounts in the prior years consolidated financial statements have been reclassified to conform to the
current year presentation, including the reclassification of restricted cash from cash and cash equivalents of $3.1 million at December 31, 2007 and 2006.

3. New Accounting Guidance

In December 2007 the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting
Standard (SFAS) No. 160, Noncontrolling Interests in Consolidated Financial Statements. SFAS 160 changes the classification of noncontrolling, or minority, interests on the balance sheet and the accounting for and reporting
of transactions between the reporting entity and holders of such noncontrolling interests. Under the new standard, noncontrolling interests are considered equity and are to be reported as an element of stockholders equity rather than within
the mezzanine or liability sections of the balance sheet. In addition, the current practice of reporting minority interest expense or benefit also will change. Under the new standard, net income will encompass the total income before minority
interest expense or benefit. The income statement will include separate disclosure of the attribution of income between controlling and noncontrolling interests. Increases and decreases in the noncontrolling ownership interest amount are to be
accounted for as equity transactions. SFAS 160 is effective for fiscal years beginning after December 15, 2008 and earlier application is prohibited.

4. Accounting
Changes

In September 2006, the FASB issued SFAS 157, Fair Value Measurements. SFAS 157 defines fair value, establishes a framework for measuring fair value
and expands disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007 for financial assets and liabilities, and for fiscal years beginning after November 15, 2008 for other
non-recurring non-financial assets and liabilities. The Company adopted SFAS 157 as of January 1, 2008, with the exception of the application of the statement to non-recurring nonfinancial assets and nonfinancial liabilities. Non-recurring
nonfinancial assets and nonfinancial liabilities for which we have not applied the provisions of SFAS 157 include those measured at fair value in goodwill impairment testing, indefinite lived intangible assets measured at fair value for impairment
testing, asset retirement obligations initially measured at fair value, and those initially measured at fair value in a business combination.

SFAS 157 establishes a
valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets
or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full
term of the financial instrument. Level 3 inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value. A financial asset or liabilitys classification within the hierarchy is determined based
on the lowest level input that is significant to the fair value measurement.

At December 31, 2008, the Company had an interest rate swap valued at $1.9 million
and cash surrender values on insurance policies totaling $1.3 million. Both assets are classified as Level 2 in the valuation hierarchy and are measured from quotes and values received from financial institutions.

5. Business Dispositions and Plant Closures

Sale of Koppers Monessen Partners LP

On October 1, 2008, Koppers Inc. and a limited partner sold Koppers Monessen Partners LP (Monessen) to ArcelorMittal S.A. for cash of $160.0 million
plus working capital of $10.4 million. Net cash proceeds, after deduction for the limited partner interest, taxes and transaction costs, were approximately $100.0 million. The Company recognized an after-tax gain of $85.9 million. Monessen is a
metallurgical furnace coke facility that was 95 percent-owned by Koppers Inc. (which served as the general partner) and five percent owned by a limited partner. Effective as of the end of the second quarter of 2008, Monessen was classified as a
discontinued operation in the Companys statement of operations and its assets and liabilities were reclassified as held for sale in the balance sheet. Accordingly, the Companys financial statements have been restated for
prior periods. Monessen was part of the Carbon Materials & Chemicals business segment.

In February 2009, the acquirer filed a notice of objection in
connection with the determination of certain assumed liabilities and has requested an adjustment to the purchase price of approximately $2.0 million. Based upon the nature of the objections cited by the acquirer, at this time, the Company does not
believe that the purchase price should be adjusted and accordingly, no adjustment to the purchase price has been provided as of December 31, 2008.

Sale of
Koppers Arch

On July 5, 2007, the Company sold its 51 percent interest in Koppers Arch Investments Pty Limited and its subsidiaries (Koppers
Arch) to Arch Chemicals Inc. for net cash proceeds of $14.3 million and recognized a gain from the sale, net of tax, of $6.7 million. Effective as of this date, Koppers Arch was classified as a discontinued operation in the Companys
statement of operations and the Companys financial statements have been accordingly restated. Koppers Arch was part of the Carbon Materials & Chemicals business segment.

Net sales and operating profit from discontinued operations for the three years ended December 31, 2008 consist of the following amounts:

7. Stock-based Compensation

In
December 2005, the Koppers Holdings Inc. board of directors and shareholders adopted the 2005 Long-Term Incentive Plan (the LTIP). The LTIP provides for the grant to eligible persons of stock options, stock appreciation rights,
restricted stock, restricted stock units, performance shares, performance awards, dividend equivalents and other stock-based awards, which we refer to collectively as the awards. Employees of Koppers Inc. participate in the LTIP. Restricted stock
units were also granted under a 2004 Restricted Stock Unit Plan which vested ratably over five years. All restricted stock units issued under this plan have vested by December 31, 2008.

Under the LTIP, the Koppers Holdings Inc. board of directors granted restricted stock units and performance stock units to certain employee participants (collectively, the stock units) in 2007 and 2008. With respect
to the 2007 grant, the restricted stock units will vest ratably each year over a period of three years for most participants, assuming continued employment. With respect to the 2008 grant, the restricted stock units will vest on the third
anniversary of the grant date, assuming continued employment by the participant. The performance stock units granted in both years will vest upon the attainment of the applicable performance objective at the end of a three-year measurement period.
The applicable performance objective is based

upon a three-year cumulative value creation calculation commencing on the first day of each grant year. The number of performance
stock units granted represents the target award and participants have the ability to earn between zero and 150 percent of the target award based upon actual performance. If minimum performance criteria are not achieved, no performance stock units
will vest.

Dividends declared on Koppers Holdings Inc.s common stock during the restriction period of the stock units are credited at equivalent value as
additional stock units and become payable as additional common shares upon vesting. In the event of termination of employment, other than retirement, death or disability, any nonvested stock units are forfeited, including additional stock units
credited from dividends. In the event of termination of employment due to retirement, death or disability, pro-rata vesting of the stock units over the service period will result. There are special vesting provisions for the stock units related to a
change in control.

In accordance with accounting standards, compensation expense for nonvested stock units is recorded over the vesting period based on the fair
value at the date of grant. The fair value of stock units is the market price of the underlying common stock on the date of grant.

The following table shows a
summary of the performance stock units as of December 31, 2008:

Also under the LTIP, the Koppers Holdings Inc. board of directors in 2008 and 2007 awarded nonqualified stock options to
certain employee participants which vest and become exercisable upon the completion of a three-year service period commencing on the third anniversary of the grant date. The stock options have a term of 10 years. There are special vesting provisions
for the stock options related to a change in control.

In accordance with accounting standards, compensation expense for unvested stock options is recorded over the
vesting period based on the fair value at the date of grant. The fair value of stock options on the date of grant is calculated using the Black-Scholes-Merton model and the assumptions listed below:

calculates the

average of the weighted vesting term and the contractual term of the option. This method was selected due to the lack of historical exercise data with respect to the
Company. Expected volatility is based on the historical volatility of Koppers Holdings Inc.s common stock and the historical volatility of certain other similar public companies. The risk-free interest rate is based on U.S. Treasury bill rates
for the expected life of the option.

The Company has not provided any U.S. tax on undistributed earnings of foreign subsidiaries or joint ventures that are
reinvested indefinitely. For the year ended December 31, 2008, the Company provided deferred tax on current year unremitted earnings of its European subsidiaries. At December 31, 2008 consolidated retained earnings of the Company included
approximately $44 million of undistributed earnings from these investments.

Koppers China Tax Holiday

As a result of being a Foreign Investment Enterprise in the manufacturing sector, the Companys 60 percent-owned joint venture in China is entitled to an income tax holiday
under which it is exempted from corporate income tax for its first two profit making years (after deducting losses incurred in previous years), and is entitled to a 50 percent reduction in the corporate tax for the succeeding three years. The effect
of the tax holiday on the Companys net income for the years ended December 31, 2008, 2007 and 2006 was approximately $0.4 million, $0.6 million and $0.3 million, respectively. The tax holiday expired on January 1, 2009.

Taxes Excluded from Net Income

The amount of income tax provision (benefit) included
in comprehensive income but excluded from net income relating to adjustments to reflect the unfunded status of employee post-retirement benefit plans is $(19.6) million, $5.0 million and $0.1 million for the years ended December 31, 2008, 2007
and 2006, respectively.

The amount of income tax benefit included in stockholders equity but excluded from net income relating to the expense for restricted
stock and employee stock options recognized differently for financial and tax reporting purposes was $0.8 million, $1.2 million and $0.4 million for the years ended December 31, 2008, 2007 and 2006, respectively.

Uncertain Tax Positions

The Company or one of its subsidiaries files income tax returns in U.S. federal jurisdiction, individual U.S.
state jurisdictions and non-U.S. jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2003.

The Company adopted the provisions of FIN 48, Accounting for Uncertainty in Income Taxes, on January 1, 2008. As a result of the adoption of FIN 48, the Company did not
recognize a material change in the liability for unrecognized tax benefits. As of December 31, 2008, the total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate, was approximately $3.2 million. A
reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

9. Segment Information

The Company has two reportable operating segments: Carbon Materials & Chemicals and Railroad & Utility
Products. The Companys reportable segments are business units that offer different products. The reportable segments are each managed separately because they manufacture and distribute distinct products with different production processes. The
business units have been aggregated into two reportable segments since management believes the long-term financial performance of these business units is affected by similar economic conditions.

The Companys Carbon Materials & Chemicals segment is primarily a supplier of carbon pitch, phthalic anhydride, creosote, carbon black and carbon black feedstock.
Carbon pitch is used primarily by the aluminum industry as a binder in the manufacture of anodes. Phthalic anhydride is used in the manufacture of plasticizers, unsaturated polyester resins, alkyd resins and dye making. Creosote is used in the
protection of timber products against insects, fungal decay and weathering. Carbon black and carbon black feedstock are used in the production of rubber tires.

The
Companys Railroad & Utility Products segment provides various products and services to railroads, including crossties (both wood and concrete), track panels and switch pre-assemblies and disposal services. The segment also supplies
treated wood poles to electric and telephone utilities and provides products to, and performs various wood treating services for construction and other commercial applications.

The Company evaluates performance and determines resource allocations based on a number of factors, the primary measure being operating profit or loss from operations. Operating profit does not include equity in earnings of
affiliates, other income, interest expense or income taxes. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies. Intersegment transactions are eliminated in
consolidation.

Revolving Credit Facility

The
Koppers Inc. revolving credit facility agreement, as amended and restated, provides for a revolving credit facility of up to $300.0 million at variable rates. The revolving credit facility replaced the Senior Secured Revolving Credit Facility on
October 31, 2008. Borrowings under the revolving credit facility are secured by a first priority lien on substantially all of Koppers Inc.s assets, including the assets of certain significant subsidiaries. The credit facility contains
certain covenants that limit capital expenditures by Koppers Inc. and restrict its ability to incur additional indebtedness, create liens on its assets, enter into leases, pay dividends and make investments or acquisitions. In addition, such
covenants give rise to events of default upon the failure by Koppers Inc. to meet certain financial ratios.

As of December 31, 2008, the Company had $283.0
million of unused revolving credit availability for working capital purposes after restrictions from certain letter of credit commitments. As of December 31, 2008, $13.6 million of commitments were utilized by outstanding letters of credit.

Senior Secured Notes

The 97/8percent Senior Secured Notes due 2013 (the Senior Secured Notes) are guaranteed, jointly and severally, on a
senior secured basis by certain of the Companys subsidiaries. Interest is payable semiannually in arrears on April 15 and October 15 of each year. The Senior Secured Notes and subsidiary guarantees are senior obligations of Koppers
Inc. and its subsidiary

guarantors, respectively, and are secured by a second priority lien on and security interest in substantially all of the assets owned by Koppers Inc. and its
subsidiary guarantors that secure Koppers Inc.s obligations under its senior secured credit facilities. On or after October 15, 2008, the Company is entitled to redeem all or a portion of the Senior Secured Notes at a redemption price of
104.938 percent of principal value, declining annually in ratable amounts until the redemption price is equivalent to the principal value.

In 2008, the Company
repurchased Senior Secured Notes with a face value of $32.5 million. The Senior Secured Notes were repurchased at a discount to face value and accordingly, the Company realized a gain of $2.1 million which was recorded as a reduction to interest
expense.

The Company has a notional $50.0 million interest rate swap to convert a portion of the Senior Secured Notes from fixed-interest rate debt to
floating-interest rate debt. Accordingly, the interest rate swap is reflected at fair value in other assets at December 31, 2008 and in other long-term liabilities at December 31, 2007. The Senior Secured Notes subject to the notional amount of the
interest rate swap is reflected at fair value at each balance sheet date. At December 31, 2008 and December 31, 2007, the impact of the interest rate swap increased (decreased) the carrying value of the Senior Secured Notes by $1.9 million
and $(0.5) million, respectively.

The indentures governing the Senior Secured Notes include customary covenants that restrict, among other things, the ability of
Koppers Inc. and its subsidiaries to incur additional debt, pay dividends or make certain other restricted payments, incur liens, merge or sell all or substantially all of the assets of Koppers Inc. or its subsidiaries or enter into various
transactions with affiliates.

Guarantees

The Companys 60-percent
owed subsidiary in China has issued a guarantee of $17.9 million in support of the Companys 30-percent investment in Tangshan Koppers Kailuan Carbon Chemical Company Limited (TKK). The guarantee relates to bank debt incurred by TKK
and expires in 2013.

Operating lease expense for 2008, 2007 and 2006 was $39.0 million, $31.1 million and $26.1 million, respectively.

16. Pensions and Post-retirement Benefit Plans

The Company and its subsidiaries
maintain a number of defined benefit and defined contribution plans to provide retirement benefits for employees in the U.S., as well as employees outside the U.S. These plans are maintained and contributions are made in accordance with the Employee
Retirement Income Security Act of 1974 (ERISA), local statutory law or as determined by the board of directors. The defined benefit pension plans generally provide benefits based upon years of service and compensation. Pension plans are
funded except for three domestic non-qualified defined benefit pension plans for certain key executives. The defined contribution plans generally provide retirement assets to employee participants based upon employer and employee contributions to
the participants individual investment account. The Company also provides retiree medical insurance coverage to certain U.S. employees and a life insurance benefit to most U.S. employees.

Effective December 31, 2006, salaried employees of the Companys U.S. qualified and corresponding non-qualified defined benefit pension plans no longer accrue additional
years of service or recognize future increases in compensation for benefit purposes. As a result of the freeze of one of the non-qualified pension plans, the Company incurred a pension curtailment loss of $1.7 million in 2006. In addition, the
Company has recently negotiated soft freezes with respect to a number of hourly defined benefit pension plans. Such negotiated agreements preclude new employees from entering the defined benefit pension plans.

In lieu of the reduction in benefits under the qualified defined benefit plan for U.S. salaried employees, the Company provides, based on age and years of service, a uniform
employer contribution of at least three percent and up to a maximum of nine percent of compensation to the salaried employees defined contribution plan. The Company also matches contributions by salaried employees at an amount equal to 50
percent of the first six percent of compensation contributed by the salaried employee. In 2007, the Companys board of directors approved the establishment of a supplemental benefit plan to restore employer non-elective contributions lost to
certain participants in the Companys defined contribution plan under U.S. tax law. This supplemental benefit plan is considered a defined-benefit pension plan under applicable accounting guidance.

With respect to U.S. hourly employees who are not eligible to participate in an hourly defined benefit pension plan, the Company provides a uniform employer contribution of three
percent of compensation to the hourly employees defined contribution plan. The Company also matches contributions by hourly employees at an amount equal to 100 percent of the first one percent and 50 percent on the next two percent of
compensation contributed by the hourly employee.

Expense related to our defined contribution plans, including the uniform employer contribution described above,
totaled $4.7 million, $3.6 million and $1.7 million for the years ended December 31, 2008, 2007 and 2006, respectively.

Effective December 31, 2006, the
Company adopted SFAS No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R) (SFAS 158). SFAS 158 requires a company to
recognize in its balance sheet an asset for a defined benefit postretirement plans overfunded status or a liability for a plans unfunded status. SFAS 158 does not change the amount of net periodic benefit expense otherwise included in
net income under existing accounting standards. The adoption of SFAS 158 resulted in an additional recognized net postretirement

Koppers Inc.2008 Annual Report



liability of $10.4 million. The impact of adoption was reflected as an adjustment to the ending balance of accumulated other comprehensive income and totaled $7.0
million, net of tax of $3.4 million. The Company adopted the measurement date provisions of SFAS 158 effective January 1, 2007 for its one pension plan with a measurement date other than December 31. The impact of the adoption of the
measurement date provisions resulted in an increase to opening retained deficit of $0.1 million on January 1, 2007.

Net periodic pension costs for 2008, 2007
and 2006 were as follows:

Basis for the Selection of the Long-Term Rate of Return on Assets

The long-term rate of return on assets assumption was determined by using the plans asset allocation as described in the plans investment policy and modeling a
distribution of compound average returns over a 20-year time horizon. The model uses asset class return, variance, and correlation assumptions to produce the expected return. The return assumptions used forward looking gross returns influenced by
the current bond yields, corporate bond spreads and equity risk premiums based on current market conditions.

In general, the long-term rate of return is the sum of
the portion of total assets in each asset class multiplied by the expected return for that class, adjusted for expected expenses to be paid from the assets. To develop the expected long-term rate of return on assets assumption, the Company
considered the historical returns and the future expectations for returns for each asset class, as well as the target asset allocation of the pension portfolio. This resulted in the selection of the 7.82 percent long-term rate of return on assets
assumption.

Investment Strategy

The Companys investment strategy
for its pension plans is to manage the plans on a going-concern basis. Current investment policy is to achieve a high return on assets, subject to a prudent level of portfolio risk, for the purpose of enhancing the security of benefits for
participants. For U.S. pension plans, this policy currently targets a 75 percent allocation to equity securities and a 25 percent allocation to debt securities. For non-U.S. pension plans, various asset allocation strategies weighted toward equity
and debt securities are in place.

Health Care Cost Trend Rates

The
2008 initial health care cost trend rate is assumed to be ten percent and is assumed to decrease gradually to five percent in 2014 and remain at that level thereafter. The assumed health care cost trend rate has a significant effect on the amounts
reported for other postretirement benefit liability. A one-percentage-point change in the assumed health care cost trend rate would have the following effects:

Incentive Plan

The Company has
established management incentive plans based on established target award levels for each participant if certain Company performance and individual goals are met. The charge to operating expense for these plans was $4.7 million in 2008, $6.7 million
in 2007 and $4.9 million in 2006.

Long-term debt  The fair value of the Companys long-term debt is estimated based on the quoted market prices for the same or similar issues or on the current rates offered to the Company for debt of the same
remaining maturities. The fair values of the revolving credit facilities and term loans approximate carrying value due to the variable rate nature of these instruments.

Investments and other long-term liabilities  The Company entered into an interest rate swap agreement to convert notional amounts of $50.0 million of fixed-interest rate debt, the Senior Secured Notes, to floating-interest rate
debt. This interest rate swap is further described in Note 2.

19. Commitments and Contingent Liabilities

The Company and its subsidiaries are involved in litigation and various proceedings relating to environmental laws and regulations and toxic tort, product liability and other
matters. Certain of these matters are discussed below. The ultimate resolution of these contingencies is subject to significant uncertainty and should the company fail to prevail in any of these legal matters or should several of these legal matters
be resolved against the Company in the same reporting period, these legal matters could, individually or in the aggregate, be material to the consolidated financial statements.

Legal Proceedings

Product Liability Cases. Koppers Inc., along with other defendants, is currently a defendant in lawsuits
filed in a variety of states in which the plaintiffs claim they suffered a variety of illnesses (including cancer) as a result of exposure to coal tar pitch sold by the defendants. There are 99 plaintiffs in 55 cases pending as of December 31,
2008 as compared to 97 plaintiffs in 52 cases at December 31, 2007. As of December 31, 2008, there are a total of 50 cases pending in state court in Pennsylvania, one case each pending in state courts in Tennessee, Washington and Illinois,
two cases pending in an Indiana state court and one case pending in the United States District Court for the District of Oregon.

The plaintiffs in all 56 pending
cases seek to recover compensatory damages, while plaintiffs in 44 cases also seek to recover punitive damages. The plaintiffs in the 50 cases filed in Pennsylvania state court seek unspecified damages in excess of the courts minimum
arbitration jurisdictional limit. The plaintiffs in the two cases filed in Indiana state court and the one case filed in Washington state court also seek unspecified damages. The plaintiff in the Oregon case seeks damages in excess of $1.8 million.
The plaintiffs in the Tennessee state court case each seek damages of $15.0 million. The plaintiff in the Illinois state court seeks compensatory damages in excess of $50,000.

The other defendants in these lawsuits vary from case to case and include companies such as Beazer East, Inc., United States Steel Corporation, Honeywell International Inc., Vertellus Specialties Inc., Dow Chemical Company,
Rust-Oleum Corporation, UCAR Carbon Company, Inc., Exxon Mobil Corporation, Chemtura Corporation, SGL Carbon Corporation, Alcoa, Inc., and PPG Industries, Inc. Discovery is proceeding in these cases. The Company has not provided a reserve for
these lawsuits because, at this time, the Company cannot reasonably determine the probability of a loss, and the amount of loss, if any, cannot be reasonably estimated. Although Koppers Inc. is vigorously defending these cases, an unfavorable
resolution of these matters may have a material adverse effect on the Companys business, financial condition, cash flows and results of operations.

Koppers
Inc. is currently a defendant in several products liability lawsuits in which the plaintiffs allege exposure to products or constituents of products sold by Koppers, including benzene, oils, solvents, pentachlorophenol and creosote. There are eleven
plaintiffs in four cases pending as of December 31, 2008 as compared to 72 plaintiffs in ten cases at December 31, 2007. Most of these cases also involve numerous other defendants in addition to Koppers Inc. The plaintiffs in one of these
cases seek compensatory damages in an unspecified amount in excess of the courts minimum jurisdictional limit. The plaintiffs in the other cases seek to recover compensatory and punitive damages in an unspecified amount in excess of the
courts minimum jurisdictional limit. The Company has not provided a reserve for these lawsuits because, at this time, the Company cannot reasonably determine the probability of loss, and the amount of loss, if any, cannot be reasonably
estimated.

Somerville Cases. Koppers Inc. is currently defending five sets of state court cases in Texas (Antu, Baade, Davis,
Hensen and Moses) involving approximately 150 plaintiffs who allegedly have worked or resided in Somerville, Texas, where Koppers Inc. has operated a wood treatment plant since 1995. Koppers has been named, but not served, in another case
(Asselin) that has 11 more plaintiffs who allegedly worked or resided in Somerville, Texas. These cases are pending in Burleson County, Texas and in Tarrant County, Texas. The Burlington Northern Santa Fe Railway Company (the
BNSF) has also been named as a defendant in these cases. The complaints allege that plaintiffs have suffered personal injuries (including death, in some cases)

##### Table of Contents



resulting from exposure to wood preservative chemicals used at the Somerville, Texas wood treatment plant. The complaints in the
Baade, Moses, Davis and Asselin cases additionally allege that plaintiffs have suffered property damage.

The complaints seek to recover various damages
for each plaintiff, including compensatory and punitive damages within the jurisdictional limits of the court for, among other things, bodily injuries, pain and mental anguish, emotional distress, medical monitoring, medical expenses, diminished
earning capacity, permanent disability, physical impairment and/or disfigurement, loss of companionship and society, loss of consortium, devaluation of property, loss of use and enjoyment of personal property, loss of use and enjoyment of real
property, property damage, property remediation costs, funeral and burial expenses and lost wages.

There are a total of 44 plaintiffs (six of whom have claims
pending against only the BNSF) in the Moses cases. These plaintiffs seek compensatory and punitive damages in an unspecified amount in excess of the courts minimum jurisdictional limit for alleged personal injuries and property damages.
There are a total of 10 plaintiffs in the Antucase, four of whom have claims pending against only the BNSF. These plaintiffs also seek compensatory and punitive damages in an unspecified amount in excess of the courts minimum
jurisdictional limit. The plaintiffs in the Hensen case seek compensatory and punitive damages in excess of $75,000 each. The Hensen case identifies a total of 93 plaintiffs, one of whom has a claim pending against only the BNSF. The
Daviscase involves one plaintiff who seeks compensatory and punitive damages in an unspecified amount in excess of the courts minimum jurisdictional limit.

The Company has not provided a reserve for these matters because, at this time, it cannot reasonably determine the probability of a loss, and the amount of loss, if any, cannot be reasonably estimated. Although Koppers Inc. is vigorously
defending these cases, an unfavorable resolution of these matters may have a material adverse effect on the Companys business, financial condition, cash flows and results of operations.

Grenada  All Cases. Koppers Inc., together with various co-defendants (including Beazer East), has been named as a defendant in toxic tort
lawsuits in state court in Mississippi (see Grenada  State Court Cases below) and in federal court in Mississippi (see Grenada  Federal Court Cases below) arising from the operation of the Grenada facility. The
complaints allege that plaintiffs were exposed to harmful levels of various toxic chemicals, including creosote, pentachlorophenol, polycyclic aromatic hydrocarbons and dioxin, as a result of soil, surface water and groundwater contamination and air
emissions from the Grenada facility and, in some cases, from an adjacent manufacturing facility operated by Heatcraft, Inc. Based on the experience of Koppers Inc. in defending previous toxic tort cases, the Company does not believe that the damages
sought by the plaintiffs in the state and federal court cases are supported by the facts of the cases. The Company has not provided a reserve for these lawsuits because, at this time, it cannot reasonably determine the probability of a loss, and the
amount of loss, if any, cannot be reasonably estimated. Although Koppers Inc. intends to vigorously defend these cases, there can be no assurance that an unfavorable resolution of these matters will not have a material adverse effect on the
Companys business, financial condition, cash flows and results of operations. See Environmental and Other Liabilities Retained or Assumed by Others for additional information.

Grenada  Federal Court Cases.

Beck Case The
complaint in this case was originally filed by approximately 110 plaintiffs. Pursuant to an order granting defendants motion to sever, the court dismissed the claims of 98 plaintiffs in the Beck case without prejudice to their right to re-file
their complaints. In December 2005, 94 of the 98 plaintiffs in the Beck case whose claims were dismissed re-filed their complaints. The plaintiffs in the 94 cases that were re-filed seek compensatory damages from the defendants of at least $5.0
million for each of eight counts and punitive damages of at least $10.0 million for each of three counts (in addition to damages in an unspecified amount for alleged trespass and nuisance). No discovery orders have been issued with respect to the 94
additional cases. The claims of 11 of the 12 plaintiffs whose claims were not dismissed are still pending. The 11 remaining plaintiffs seek compensatory damages from the defendants in an unspecified amount and punitive damages of $20.0 million for
each of four counts.

The first of these trials commenced on April 17, 2006, and the jury returned a verdict of 20 percent of $845,000 against Koppers Inc. for
compensatory damages and no liability for punitive damages. Subsequent to the verdict, the court reduced the compensatory damages judgment by $60,000 to $785,000. Koppers Inc. appealed the judgment entered against it to the United States Court of
Appeals for the Fifth Circuit. The Court of Appeals granted a reversal of the district courts judgment on June 30, 2008. The plaintiff filed a petition for rehearing with the United States Court of Appeals and on October 23, 2008,
the

Koppers Inc.2008 Annual Report



Court of Appeals denied plaintiffs petition for rehearing. In February 2009 the district court denied plaintiffs motion to consolidate three of the
remaining 11 cases for trial. A discovery schedule has been set for the next case that will go to trial.

Ellis Case  There are approximately 1,180
plaintiffs in this case. Each plaintiff seeks compensatory damages from the defendants of at least $5.0 million for each of seven counts and punitive damages of at least $10.0 million for each of three counts (in addition to damages for an
unspecified amount for trespass and nuisance). The Ellis complaint also requests injunctive relief. These cases have been stayed pending the completion of the trials for the remaining 11 plaintiffs in the Beck case.

Grenada  State Court Cases. The state court cases were brought on behalf of approximately 214 plaintiffs in five counties in Mississippi. Each plaintiff
seeks compensatory damages from the defendants of at least $5.0 million for each of up to eight counts and punitive damages of at least $10.0 million for each of three counts. Certain plaintiffs also seek damages for alleged trespass and private
nuisance in unspecified amounts together with injunctive relief. The Mississippi Supreme Court ordered that the plaintiffs in the pending state court cases filed in counties other than Grenada County (approximately 110 cases) be severed and
transferred to Grenada County. Plaintiffs counsel attempted to transfer ten such cases to Grenada County but all ten cases were dismissed by the Court. Motions to dismiss the remaining plaintiffs in the four non-Grenada County cases are
pending. In February 2009, the court in Washington County entered an order granting plaintiffs 30 days from January 30, 2009 to show good cause why the cases pending in Washington County should not be dismissed.

With respect to the state court case that was originally filed in Grenada County, the court granted the defendants motion to sever the claims of these plaintiffs for improper
joinder. These plaintiffs then filed 104 individual complaints in Grenada County. Of these, 40 have been dismissed to date. On August 28, 2008, the Circuit Court of Grenada County granted summary judgment in favor of the Company in 39 cases and
the Plaintiffs filed motions to reconsider the summary judgment orders. The motions to reconsider were denied by the Circuit Court in November 2009. The Circuit Court also granted motions to dismiss for want of prosecution in three cases (two of
which also had pending motions for summary judgment). Plaintiffs filed notices of appeal with the Mississippi Supreme Court in these cases. The Mississippi Supreme Court has not yet ruled on plaintiffs appeal. The Company filed motions to
dismiss, or in the alternative, for summary judgment with regard to the remaining 18 cases in Grenada County. On February 12, 2009, the court granted summary judgment in favor of the Company in these 18 cases. The deadline for plaintiffs to
appeal this summary judgment order has not yet expired.

Discontinued Operations. The Company sold its 51 percent interest in Koppers Arch on July 5,
2007 (see Note 5) to Arch Chemicals, Inc. and has provided an indemnity to Arch Chemicals for the Companys share of liabilities, if any, arising from certain types of obligations and claims that arose prior to the Companys sale of its
interest in Koppers Arch. Koppers Inc. has received three notices from Arch Chemicals asserting claims for indemnification under the share purchase agreement. The first notice relates to environmental issues related to the condition of certain
property associated with the Auckland, New Zealand operations of Koppers Arch Wood Protection (NZ) Limited. Reserving all rights, Koppers has agreed to participate in the payment of attorneys fees and related expenses relating to this matter
until further notice. The two other notices relate to legal actions that have been filed in the High Court of New Zealand Auckland Registry against a third party and against Arch Wood Protection (NZ) Limited by a competitor of Arch Wood Protection
(NZ) Limited. The competitor/plaintiff alleges, among other things, claims of defamation, injurious falsehood, conspiracy and violation of the New Zealand Fair Trading Act. Reserving all rights, Koppers has agreed to participate in the payment of
attorneys fees and related expenses relating to these matters until further notice. The plaintiff seeks damages of approximately $10.8 million. The Company has not provided a reserve for these matters because, at this time, it cannot
reasonably determine the probability of a loss, and the amount of loss, if any, cannot be reasonably estimated. An unfavorable resolution of these matters may have a material adverse effect on the Companys business, financial condition, cash
flows and results of operations.

Other Matters. In January 2009, the Company received questionnaire from the India Ministry of Commerce and Industry inquiring
about the Companys sales of carbon black into the Indian market. The Association of Carbon Black Manufacturers contend that carbon black manufacturers in China, Russia, Iran, Australia, Malaysia and Thailand are dumping carbon black into the
Indian market and they are seeking the imposition of dumping duties on a retrospective basis. The Company is currently preparing a response to the questionnaire.

Reversal of reserves in 2008 primarily relates to the reversal of the Grenada federal court verdict that was reversed by an
appeals court. Expense accruals and cash expenditures in 2007 primarily relate to the New Zealand Commerce Commission (NZCC) matter and the business divestiture relates to Koppers Arch (Note 5). Expense for 2006 consists primarily of the
amount of the verdict rendered against Koppers Inc. in May 2006 related to the Grenada litigation and other costs related to the NZCC matter. Cash expenditures for 2006 consisted of the Companys penalty related to the NZCC matter.

Environmental and Other Litigation Matters

The Company is subject to federal, state, local
and foreign laws and regulations and potential liabilities relating to the protection of the environment and human health and safety including, among other things, the cleanup of contaminated sites, the treatment, storage and disposal of wastes, the
discharge of effluent into waterways, the emission of substances into the air and various health and safety matters. The Companys subsidiaries expect to incur substantial costs for ongoing compliance with such laws and regulations. The
Companys subsidiaries may also face governmental or third-party claims, or otherwise incur costs, relating to cleanup of, or for injuries resulting from, contamination at sites associated with past and present operations. The Company accrues
for environmental liabilities when a determination can be made that they are probable and reasonably estimable.

Environmental and Other Liabilities Retained or
Assumed by Others. The Company has agreements with former owners of certain of its operating locations under which the former owners retained, assumed and/or agreed to indemnify the Company against certain environmental and other
liabilities. The most significant of these agreements was entered into at Koppers Inc.s formation on December 29, 1988 (the Acquisition). Under the related asset purchase agreement between the Company and Beazer East, subject
to certain limitations, Beazer East retained the responsibility for and agreed to indemnify the Company against certain liabilities, damages, losses and costs, including, with certain limited exceptions, liabilities under and costs to comply with
environmental laws to the extent attributable to acts or omissions occurring prior to the Acquisition and liabilities related to products sold by Beazer East prior to the Acquisition (the Indemnity). Beazer Limited, the parent company of
Beazer East, unconditionally guaranteed Beazer Easts performance of the Indemnity pursuant to a guarantee (the Guarantee). In 1998, the parent company of Beazer East purchased an insurance policy under which the funding and risk of
certain environmental and other liabilities relating to the former Koppers Company, Inc. operations of Beazer East (which includes locations purchased from Beazer East by the Company) are underwritten by Centre Solutions (a member of the Zurich
Group) and Swiss Re. Beazer East is a wholly-owned indirect subsidiary of Heidelberg Cement AG.

The Indemnity provides different mechanisms, subject to certain
limitations, by which Beazer East is obligated to indemnify Koppers Inc. with regard to certain environmental, product and other liabilities and imposes certain conditions on Koppers Inc. before receiving such indemnification, including, in some
cases, certain limitations regarding the time period as to which claims for indemnification can be brought. In July 2004, Koppers Inc. and Beazer East agreed to amend the environmental indemnification provisions of the December 29, 1988 asset
purchase agreement to extend the indemnification period for pre-closing environmental liabilities through July 2019. As consideration for the amendment, Koppers Inc. paid Beazer East a total of $7.0 million and agreed to share toxic tort litigation
defense costs arising from any sites acquired from Beazer East. The July 2004 amendment did not change the provisions of the Indemnity with respect to indemnification for non-environmental claims, such as product liability claims, which claims may
continue to be asserted after July 2019.

Koppers Inc.2008 Annual Report



Qualified expenditures under the Indemnity are not subject to a monetary limit. Qualified expenditures under the Indemnity include (i) environmental cleanup liabilities required by third parties, such as investigation,
remediation and closure costs, relating to pre-December 29, 1988, or Pre-Closing, acts or omissions of Beazer East or its predecessors; (ii) environmental claims by third parties for personal injuries, property damages and natural
resources damages relating to Pre-Closing acts or omissions of Beazer East or its predecessors; (iii) punitive damages for the acts or omissions of Beazer East and its predecessors without regard to the date of the alleged conduct and
(iv) product liability claims for products sold by Beazer East or its predecessors without regard to the date of the alleged conduct. If the third party claims described in sections (i) and (ii) above are not made by July 2019, Beazer
East will not be required to pay the costs arising from such claims under the Indemnity. However, with respect to any such claims which are made by July 2019, Beazer East will continue to be responsible for such claims under the Indemnity beyond
July 2019. The Indemnity provides for the resolution of issues between Koppers Inc. and Beazer East by an arbitrator on an expedited basis upon the request of either party. The arbitrator could be asked, among other things, to make a determination
regarding the allocation of environmental responsibilities between Koppers Inc. and Beazer East. Arbitration decisions under the Indemnity are final and binding on the parties.

Contamination has been identified at most of the Companys manufacturing and other sites. Three sites currently owned and operated by the Company in the United States are listed on the National Priorities List promulgated
under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (CERCLA). Currently, at the properties acquired from Beazer East (which include all of the National Priorities List sites and all but one
of the sites permitted under the Resource Conservation and Recovery Act (RCRA)), a significant portion of all investigative, cleanup and closure activities are being conducted and paid for by Beazer East pursuant to the terms of the
Indemnity. In addition, other of the Companys sites are or have been operated under RCRA and various other environmental permits, and remedial and closure activities are being conducted at some of these sites.

To date, the parties that retained, assumed and/or agreed to indemnify the Company against the liabilities referred to above, including Beazer East, have performed their
obligations in all material respects. The Company believes that, for the last three years, amounts paid by Beazer East as a result of its environmental remediation obligations under the Indemnity have averaged in total approximately $11.7 million
per year. Periodically, issues have arisen between Koppers Inc. and Beazer East and/or other indemnitors that have been resolved without arbitration. Koppers Inc. and Beazer East engage in discussions from time to time that involve, among other
things, the allocation of environmental costs related to certain operating and closed facilities.

If for any reason (including disputed coverage or financial
incapability) one or more of such parties fail to perform their obligations and the Company is held liable for or otherwise required to pay all or part of such liabilities without reimbursement, the imposition of such liabilities on the Company
could have a material adverse effect on its business, financial condition, cash flows and results of operations. Furthermore, the Company could be required to record a contingent liability on its balance sheets with respect to such matters, which
could result in a negative adjustment to the Companys net worth.

Domestic Environmental Matters. Koppers Inc. is named as a potentially
responsible party (a PRP) at two CERCLA Superfund sites and believes it is a minor participant in each of the sites. The Company has provided a reserve for CERCLA sites totaling $0.2 million as of December 31, 2008.

The Company has been named as a PRP at a third site, the Portland Harbor CERCLA site located on the Willamette River in Oregon. The Company has replied to an EPA Information
request and is participating in discussions with existing PRP members to formulate an appropriate allocation methodology and execute a formal PRP agreement. The Company currently operates a coal tar pitch terminal near the site. The current estimate
for past costs incurred in the remedial investigation/feasibility study is $100 million. Separate from the EPA activities, a natural resources damages assessment is being conducted by a local trustee group. The Company has not provided a reserve for
this matter because, at this time, it cannot reasonably determine the probability of a loss, and the amount of loss, if any, cannot be reasonably estimated. An unfavorable resolution of this matter may have a material adverse effect on the
Companys business, financial condition, cash flows and results of operations.

The Illinois Environmental Protection Agency (the IEPA) has requested
that Koppers Inc. conduct a voluntary investigation of soil and groundwater at its Stickney, Illinois carbon materials and chemicals facility. The IEPA advised Koppers Inc. that it made such request as a result of a reported release of oil-like
material from Koppers Inc.s property into an adjacent river canal. Koppers Inc. conducted such investigation in cooperation with Beazer East. The Company and Beazer East have engaged consultants to assist the Company in preparing a remediation
strategy and an estimate of potential costs and has submitted a plan to conduct the remediation on this site. The Company has provided a reserve for this matter totaling $1.6 million as of December 31, 2008.

In August 2005, the
Pennsylvania Department of Environment Protection (the PADEP) proposed a fine related to alleged water discharge exceedances from a storm water sewer pipe at the Companys tar distillation facility in Clairton, Pennsylvania. In
December 2006, the Company reached a preliminary settlement of the fine with the PADEP for $0.5 million, subject to the execution of a consent order that the Company is currently negotiating with the PADEP. Accordingly, the Company has reserved the
amount of the settlement. The Company also proposed to undertake certain engineering and capital improvements to address this matter. In December 2007, the Company agreed to contribute the capital improvements, primarily a new sewer line, to the
city of Clairton and accordingly, has provided a reserve of $1.6 million as of December 31, 2008.

In September 2007, Koppers Inc. and the EPAs Office of
Suspension and Disbarment reached an agreement to an 18-month extension to Koppers Inc.s compliance agreement related to violations at Koppers Inc.s Woodward Coke facility prior to its closure in January 1998. The extended compliance
agreement expired in January 2009.

Australian Environmental Matters. Soil and groundwater contamination has been detected at certain of the Companys
Australian facilities. At the Companys tar distillation facility in Newcastle, New South Wales, Australia, soil contamination from an abandoned underground coal tar pipeline and other groundwater contamination has been detected at a property
adjacent to the facility. In December 2006 the Company and the owner of the adjacent property reached an agreement in principle pursuant to which the Company will contribute $1.4 million and the owner of the adjacent property will contribute $4.6
million toward remediation of the property. Subject to the approval of a remediation action plan by local environmental authorities, the agreement in principle provides that the Company will assume responsibility for the management of the
remediation effort and will indemnify the current owner for any remediation costs in excess of its agreed contribution. At the completion of the remediation, the agreement in principle provides that the property will transfer to the Company. The
Company has reserved its expected total remediation costs of $1.4 million at December 31, 2008.

Other Australian environmental matters include soil and
groundwater remediation at two former wood products facilities in Australia which are being prepared for future sale. With respect to the first facility in Hume, Australia, the soil remediation is substantially complete. In the fourth quarter of
2006, a Phase II environmental assessment was completed that indicated estimated groundwater remediation costs of between $0.5 million and $1.7 million. No remediation work has commenced to date. With respect to the second facility in Thornton,
Australia, a draft remediation action plan has been developed to address contaminated soil and groundwater contamination. The Company has reserved approximately $3.1 million for remediation costs at these sites which represents its best estimate of
groundwater and remaining soil remediation.

Expense for 2008 consisted primarily of accruals related to the Thornton site. Expense for 2007 consisted primarily of
accruals for estimated remediation costs at the Stickney, Illinois and Clairton, Pennsylvania tar distillation plants, closed facilities remediation in the U.S. and Australia, estimated remediation costs at the Newcastle tar distillation facility
and soil remediation at a site in Australia. Expense for 2006 primarily included accruals for soil and groundwater remediation at the Companys former wood products facility in Hume, Australia, estimated settlement costs related to the
Companys Clairton facility, CWA assessments, waste material disposal at certain Koppers Arch facilities in Australia and New Zealand and soil disposal costs at the Companys facility in Port Clarence, UK. Reversals of reserves for 2006
primarily included estimated settlement costs related to the Companys Clairton facility.

Koppers Inc.2008 Annual Report



Contingent Liabilities

In the third quarter of 2008, the Company retired from service an owned vessel used to transport carbon
materials products and raw materials. In connection with this retirement and under a contractual arrangement with the vessels operator, the Company and the vessels operator reached an agreement to share in the cost of severance benefits
the vessels operator owes to its employees. In December 2008 the Company paid approximately $1.0 million in connection with the agreement and was released from any future obligation that the vessels operator has to its employees.

20. Related Party Transactions

Schnader Harrison Segal & Lewis LLP
provided counsel to the Company during 2008 and 2007. Clayton A. Sweeney, a Director and shareholder of the Company, is also of counsel to Schnader Harrison Segal & Lewis LLP. In both 2008 and 2007, the Company paid a total of $0.1 million
in legal fees to this firm.

The Company had entered into a consulting agreement in 1999 with Robert Cizik who was a director of the Company at that time. The
consulting agreement included a provision which provided for a $0.6 million interest-free loan from the Company for the purchase of 140,467 shares of restricted common stock. The loan was repaid in May 2008 concurrent with Mr. Ciziks
retirement from the Board of Directors.

The Company had an advisory and consulting agreement with Saratoga pursuant to which the Company paid a management fee of
$150,000 per quarter to Saratoga in lieu of Directors fees to the Saratoga Director. In addition, Saratoga provided the Company with financial advisory services in connection with significant business transactions. For such services, the
Company paid Saratoga compensation comparable to compensation paid for such services by similarly situated companies. During 2006 the Company paid Saratoga $0.3 million related to management fees. The advisory services agreement was terminated in
February 2006 in conjunction with the completion of the Companys initial public offering, and an affiliate of Saratoga Partners was paid a financial advisory services termination fee of $3.0 million in 2006.

21. Financial Information for Subsidiary Guarantors

The Companys payment obligations under the 97/8percent Senior Secured Notes due 2013 (the Senior
Secured Notes) are fully and unconditionally guaranteed on a joint and several basis by Koppers (the parent) subsidiaries Koppers Australia Pty. Limited, and Koppers Industries of Delaware, Inc. (collectively, the Guarantor
Subsidiaries). The Notes have not been guaranteed by Koppers Assurance, Inc., Koppers Europe, Koppers Arch Investments Pty Ltd, KSA Limited Partnership, or Koppers China (collectively, the Non-Guarantor Subsidiaries). The principal
elimination entries eliminate investments in subsidiaries and intercompany balances and transactions.
