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, including 27 manufacturing facilities located in the United States, Australia, China, the United Kingdom and Denmark. For the twelve months ended December 31, 2007, we had net sales
of $1,327.9 million and net income of $74.9 million.



We operate two
principal businesses: Carbon Materials & Chemicals and Railroad & Utility Products. Through our Carbon Materials & Chemicals business (64 percent of 2007 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 (36 percent of 2007 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.



Our operations are, to a substantial extent, vertically integrated and employ a variety of processes, as illustrated in the following flow diagram:

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) 97/8percent 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 senior secured 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



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.



We believe that demand for aluminum and railroad track maintenance substantially drive the growth in our two principal businesses. Through our leading market
positions and global presence, we believe we are uniquely well-positioned to capitalize on favorable trends within our end-markets. According to the November 2007 CRU International Report, worldwide aluminum production increased 13 percent to
38 million metric tons in 2007 and was expected to grow by eleven percent in 2008 and six percent in 2009. Carbon pitch requirements for the aluminum industry were four million metric tons in 2007 and are expected to grow as a function of
growth in aluminum production.



The railroad crosstie business is
benefiting and will likely continue to benefit from positive general economic conditions in the railroad industry and from expected increases in spending on both new track and existing track maintenance. The Railway Tie Association (RTA)
estimates that approximately 19.5 million wood crossties for Class 1 railroads were purchased in the United States and Canada in 2007 and approximately 19.6 million wood crossties are projected to be purchased in 2008.



Carbon Materials & Chemicals



Our Carbon Materials & Chemicals business manufactures six principal
products: (a) carbon pitch, used in the production of aluminum and steel; (b) phthalic anhydride, used in the production of

##### Table of Contents

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; (e) naphthalene, used primarily as a surfactant in the production of concrete; and (f) furnace coke, used in steel and iron production. Carbon pitch, phthalic anhydride,
creosote (and carbon black feedstock) and naphthalene are produced through the distillation of coal tar, a by-product of the transformation of coal into coke. 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. For 2007, 2006 and 2005, 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 as well as from our Monessen facility. 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. For example, we declared force majeure in July 2006 with respect to certain North American customer contracts as a result of an extended strike and reduced coke production at certain suppliers, which resulted in a
shortage of raw materials needed to fulfill customer commitments. We subsequently declared an end to the force majeure declaration in December 2006.



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 officer 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

##### Table of Contents

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.



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 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 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 33 percent of our total creosote production was sold internally
in 2007. Our wood treating plants in the United States and our carbon black facility in Australia purchase substantially all of their creosote 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 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. In 2007 we completed a capital project to expand our capacity at our carbon black facility by approximately 40 percent. Coal tar based carbon black is used in the manufacture of rubber tires as well as other specialty applications.



Furnace Coke



We produce furnace coke at one plant in the United States using coal as the primary
raw material. Sales terms are negotiated by a centralized sales department in the United States, and all coke is currently sold to one customer under a three-year sales contract which expires December 31, 2009. The contract also has certain
renewal provisions beyond the three year term.



Furnace coke is a carbon
and fuel source required in the manufacturing of steel. Coal, the primary raw material, is carbonized in oxygen-free ovens to obtain the finished product. Coke manufacturers are either an integrated part of a steel company or, as in our case,
operate independently and are known as merchant producers.



Our coke business consists of one production facility located in Monessen, Pennsylvania, which produces furnace coke. The plant consists of two batteries with a total of 56 ovens and has a total capacity of approximately 360,000 tons of
furnace coke per year. All of the ovens were rebuilt in 1980 and 1981, which, together with recent improvements, makes our Monessen facility one of the most modern coking facilities in the United States.



Other Products



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



Seasonality



Demand for certain products may decline during winter months due to weather conditions. As a result, operating results may vary from
quarter to quarter depending on the severity of weather conditions and other variables affecting our products.



Acquisitions & Expansions



Reilly Acquisition. On April 28, 2006, we acquired certain assets of Reilly Industries, Inc.s (Reilly) carbon materials business. The
purchased assets consist primarily of inventories, customer sales contracts, raw material supply contracts, rail car leases and a non-compete agreement. We have integrated the additional tar distillation production at our existing facilities in the
U.S. Net sales from the date of acquisition to December 31, 2006 totaled $55.8 million.



China Expansion.In November 2007, Tangshan Koppers Kailuan Carbon Chemical Company Limited (TKK) was established which will construct and operate a new tar distillation facility in the Hebei Province near
the Jintang 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 2008. In December 2007, we announced the approval of 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. The expansion is expected to be operational in late 2008.

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, 2007, 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 13 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
21.2 million replacement crossties (both wood and non-wood) purchased during 2007. 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. These relationships have been further strengthened recently due to our ability to absorb additional treating volumes into our existing infrastructure. 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.



Historically, investment trends in track maintenance by
domestic railroads have been linked to general economic conditions in the country. During recessions, the railroads have typically deferred track maintenance until economic conditions improve. Recently, the Class 1 railroads have increased their
spending on track maintenance, which has caused an increase in demand for railroad crossties. Management believes this increase in demand will continue for the near term.



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.

##### Table of Contents

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 eleven 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 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 1991, we acquired a 50 percent-owned partnership interest in KSA Limited Partnership, a concrete crosstie
manufacturing facility in Portsmouth, Ohio, in order to take advantage of this growth opportunity. In 2007, an estimated 1.5 million concrete crossties were installed by Class 1 railroads, representing approximately ten 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 and installation of a concrete crosstie is much higher than that of a wood crosstie, 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 and fir 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 2007, 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 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 Lehigh Cement Company. KSA Limited Partnership also provides concrete turnouts, used in rail traffic switching, and used crosstie rehabilitation.

##### Table of Contents

TKK was established in November 2007 and will construct and operate a new tar distillation facility in the Hebei
Province near the Jintang Port. The Company holds a 30 percent investment in TKK which is expected to commence production in late 2008.



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.
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 for 2007, 2006 and 2005 were $2.8 million,
$2.5 million and $2.8 million, 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.



Segment
Information



Please see Note 10, 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, Canada, the United Kingdom, Scandinavia and Australia, our remaining sales and income are generated from operations in developing regions, such as China.



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, 2007 and 2006 were approximately $12.5 million and $5.6 million, respectively, which include provisions primarily for
environmental fines and soil remediation. For the last three years, our annual capital expenditures in connection with environmental control facilities averaged approximately $4.4 million, and annual operating expenses for environmental matters,
excluding depreciation, averaged approximately $11.2 million. Management estimates that capital expenditures in connection with matters relating to environmental control facilities will be approximately $13.7 million for 2008. 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 20 of the Notes to Consolidated Financial Statements, Commitments and Contingent Liabilities.



Employees and Employee Relations



As of December 31, 2007, we had 627 salaried employees and 1,300 non-salaried employees. Listed below is a breakdown of employees

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



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. Additionally, some of the purchasers of our coke are capable of supplying a portion of their needs from their own
coke production as well as from suppliers outside the United States who are able to import coke into the United States and sell it at prices competitive with those of U.S. suppliers. 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.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The principal customers for our coke are U.S. integrated steel producers. The prices at which we will be able to sell our coke in the future will be greatly affected by the
demand for coke from the steel industry and the supply of coke from the U.S. integrated steel producers own coke production and from foreign sources.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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 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, 2007, our top ten customers accounted for approximately 50 percent of our net sales. During this period, our two largest customers each accounted for



14



---

##### Table of Contents

approximately ten percent and eight percent, respectively, of our total net sales. Additionally, an integrated steel company representing approximately five percent of
total net sales is the only customer for our furnace coke, with a contract to take 100 percent of our coke production through 2009. 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.



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, several of which we own or lease, to deliver raw materials to our facilities and finished goods to 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 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.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We experienced a shortage of coal tar that caused us to declare force majuere with respect to our North American carbon materials customers from July 2006 through
December 2006. The events which caused the shortage were beyond our control and may experience similar shortages of coal tar in the future.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In certain circumstances coal tar may also be used as an alternative to fuel. Recent increases in energy prices have resulted in higher coal tar costs which we attempt to
pass through to our customers. If these costs cannot be passed through, 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.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Metallurgical coal is the primary raw material used in the production of coke. An increase in the price of metallurgical coal, or a prolonged interruption in its supply,
could increase our operating expenses.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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, 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, 2007 and December 31, 2006 were $12.5 million and $5.6
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 $4.4
million, and annual operating expenses for environmental matters, excluding depreciation, averaged approximately $11.2 million. Management estimates that capital expenditures in connection with matters relating to environmental control facilities
will be approximately $13.7 million for 2008. 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 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 20 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 assumed the liability for and indemnified us against (among other things) certain clean-up liabilities for contamination occurring prior to the purchase date at sites acquired from Beazer East and
third-party claims arising from such contamination (the Indemnity). Beazer East and Beazer Limited 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



17



---

##### Table of Contents

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. Koppers Inc. and Beazer East are currently 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 additional 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 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 roofing and 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, 2007, net sales from our products sold by Koppers Europe ApS and
Koppers Australia Pty Ltd. (Koppers Australia) accounted for approximately 34 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



18



---

##### Table of Contents

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 and improve our market position. 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 facility. In April 2006, in the first Grenada case to be tried, a jury returned a verdict against us of 20 percent of $845,000, which was
subsequently reduced to 20 percent of $785,000, for compensatory damages and no liability for punitive damages. We have appealed the judgment but the appellate court has not yet ruled on our appeal. Although we intend to vigorously defend the
remaining Grenada and other similar claims against us, an unfavorable verdict or other resolution of these or any future claims against us could have a material affect on our business, financial condition, cash flows and results of operations. A
further description of the material claims against us is included in Note 20 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 Acquisition. Beazer East and
Beazer Limited, pursuant to the Guarantee, may not continue to meet their obligations. 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.

##### Table of Contents

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.



Governmental investigations include the New Zealand Commerce Commission (the NZCC) claim with respect to competitive practices in the New Zealand wood
preservative industry. This claim was filed against a number of corporate and individual defendants, including certain subsidiaries of Koppers Arch Investments Pty Limited (Koppers Arch). Until July 5, 2007, we had a 51 percent
ownership interest in Koppers Arch. On that date, we sold our 51 percent interest in Koppers Arch to Arch Chemicals, Inc. In February 2006, Koppers Arch entered into a Cooperation Agreement with the NZCC and paid a fine of $2.6 million. Koppers Arch
also entered into a cooperation agreement with the Australian Competition and Consumer Commission.



In January 2007, Timtech Chemicals Limited (Timtech) filed a Statement of Claim in the High Court of New Zealand against a number of corporate and
individual defendants, including KANZ, KAI, Koppers Australia and a number of other corporate and individual defendants. The Statement of Claim alleges various causes of action against the defendants including claims related to breaches of the New
Zealand Commerce Act of 1986. Timtech is seeking damages against all defendants in the amount of $3.9 million plus exemplary damages and pre-judgment interest in an unspecified amount. In connection with the sale of our 51 percent interest in
Koppers Arch Investments Pty, we provided an indemnity to the Ach Chemicals, Inc. for our share of liabilities, if any, arising from certain litigation and claims including the Timtech litigation and claims arising from the New Zealand Commerce
Commission and the Australian Competition and Consumer Commission investigations.



Although the Timtech case will be vigorously defended, an unfavorable resolution of this matter may have a material adverse effect on our business, financial condition, cash flows and results of operations. It is possible that other civil
claims could be filed against us arising from alleged breaches of New Zealand and Australian competition laws. Such other claims, if filed and resolved unfavorably, could have a material adverse effect on our business, financial condition, cash
flows and results of operations.



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 20 different labor unions and are covered under numerous labor contracts. The United
Steelworkers of America currently represent approximately 550 of our employees at eight of our facilities and, therefore, represent the largest number of our unionized employees. Labor contracts that expire in 2008 cover approximately 25 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.

##### Table of Contents

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, 2007, our benefit obligation under our defined benefit pension plans exceeded the fair value of plan assets by approximately $27.1 million.
The underfunding was caused, in part, by fluctuations in the financial markets that have caused the valuation of the assets in our defined benefit pension plans to be lower than anticipated. Our obligations for other post-retirement benefit
obligations are unfunded. During the years ended December 31, 2007 and December 31, 2006, we contributed $13.5 million and $14.6 million, respectively, to our post-retirement benefit plans. 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, 2007, we
and our subsidiaries had approximately $270.8 million of indebtedness (excluding trade payables and intercompany indebtedness), consisting primarily of our Senior Secured Notes and $43.6 million of indebtedness under our senior secured credit
facility.



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 senior secured 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 senior secured 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 future 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 senior
secured 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.

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 2007, 2006 and 2005 the Company paid cash dividends of $14.7
million, $16.6 million and $16.0 million, respectively.



|ITEM 6. | SELECTED FINANCIAL DATA

Obligations. Previously, we had not been recognizing amounts related to asset retirement obligations. Under the new accounting method, we now recognize asset retirement obligations in the period in which they are incurred if a reasonable
estimate of a fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset.

|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 will construct and operate a new tar distillation facility in the Hebei Province near the Jintang
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 2008. In December 2007, we announced the approval of 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. The expansion is expected to become operational in late 2008.



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 earnings
per share and our financial statements have been accordingly restated. Koppers Arch was a manufacturer of timber presentation chemicals.



In April 2006 we acquired certain assets of Reilly Industries, Inc.s (Reilly) carbon materials business. The purchased assets consist primarily of
inventories, customer sales contracts, raw material supply contracts, rail car leases, pitch melting assets and a non-compete agreement. We have integrated the additional tar distillation production into our existing facilities in the U.S.



Outlook



Trend Overview



Our businesses and results of operations are impacted by various competitive and other factors including (i) raw materials pricing and availability, in
particular the amount and quality of coal tar available in global markets, which could be negatively impacted by the relative increase in the value of coal tar as a fuel source as a result of higher energy prices; (ii) competitive conditions in
global carbon pitch markets; and (iii) low margins in the utility pole business.

##### Table of Contents

Raw material prices have increased over the past several years, including our primary feedstocks: coal tar, coal
and lumber. 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, such as those occurring during 2007 and 2006, have resulted in margin dilution because only the increased cost is passed on to the customer. We believe that the global restructuring of the CM&C business has
stabilized with respect to the North American and European markets, and that future expansion of the aluminum (and carbon pitch) markets will be primarily in Asian and Middle Eastern countries. We expect to expand into these markets to the extent
that the economics justify such expansion. 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 to reduce market share if warranted. Conditions in the U.S. economy may have an impact on the demand for certain products, particularly coal tar chemicals, which are used in various applications related to consumer products and
the housing industry. Net sales over the past several years have been significantly impacted by favorable foreign exchange rates in Australia, Denmark, China and the United Kingdom. In the event this trend reverses, net sales could decline if
volumes do not increase.



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 it may experience material fluctuations in quarterly operating results. Historically, our operating results can
be 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., 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. With respect to other products, furnace coke realized higher
pricing totaling one percent as compared to the prior year. Changes in foreign exchange rates between the U.S. dollar and Australian and European currencies resulted in higher sales of five 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:

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 $162.1 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
$0.2 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 Koppers Holdings Inc.s initial public offering. The proceeds from the offering were used to redeem $101.7 million of the 9 7/8percent 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 $21.1 million higher when compared to the prior year period due primarily to the increase in pretax income of $65.6 million. Our effective income tax rate for the
year ended December 31, 2007 was 31.1 percent as compared to the prior year period of 29.3 percent. The increase in the effective tax rate is due primarily to the smaller impact (in proportion to pretax book income) from the non-conventional
fuel tax credit in the current year period. This effect was partially offset by a favorable impact from the mix of earnings between the U.S. and Australia and the ability to claim the domestic production activities deduction in the current year
period.



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 $82.4 million due primarily to improved prices for carbon pitch, refined tar, creosote, and furnace coke of $49.2 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 11.5 percent from 9.2 percent between periods reflecting an increase in pricing for carbon
materials, creosote, furnace coke 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. Excluding these amounts, the operating profit as a percentage of net sales increased to 13.1 percent in 2007 from 9.7 percent.

black feedstock totaling $15.4 million. In addition, changes in foreign exchange rates contributed $17.1 million of increased sales. Operating profit as a percentage
of net sales increased to 13.3 percent from 11.9 percent between periods reflecting an increase in pricing for carbon pitch, naphthalene and carbon black feedstock due primarily to higher raw material costs.



European CM&C sales increased $46.2 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.



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.

Net sales for CM&C
increased by 20 percent, due primarily to $55.8 million of net sales from the Reilly acquisition as well as pricing increases for carbon pitch of $23.1 million, phthalic anhydride of $12.1 million, naphthalene of $11.1 million, and carbon black
feedstock of $8.6 million. These increases were partially offset by lower carbon pitch volumes of $6.4 million and lower naphthalene volumes of $6.9 million. The price increase for carbon pitch was due primarily to higher raw material

costs, and the phthalic anhydride and carbon black feedstock prices were favorably impacted by higher oil prices. The price increase for phthalic anhydride was due
primarily to higher costs for orthoxylene, which is a petroleum based feedstock used by all domestic competitors, but which is supplemented in our domestic operations by the use of internally produced naphthalene. Additionally, the impact of foreign
exchange rates increased sales by $4.5 million, freight costs in the U.S. increased by $3.3 million (due primarily to the force majeure declaration in 2006), and the increase in sales from a full year of the Lambson acquisition amounted to
$6.8 million. Lambson Speciality Chemicals Limited was acquired in the second quarter of 2005.



Net sales for R&UP increased four percent due primarily to increases in volumes and prices for railroad crossties of $4.9 million and $5.0 million, respectively. Additionally, volumes and prices for crosstie treating
services experienced an increase of $3.2 million and $5.0 million, respectively. Lower volumes for utility distribution poles of $7.8 million were largely offset by increased prices of $7.9 million. The increase in prices for railroad crossties was
due primarily to higher raw material prices, the increase in volumes for crossties and crosstie treating services was due to the exit from the business of a major competitor, and the reduction in volumes for utility poles was the result of targeting
higher margin business.



Operating profit for CM&C increased
primarily due to higher sales and synergies derived from the Reilly acquisition as operating profit as a percentage of net sales increased by 0.4 percent.



Operating profit for R&UPdecreased primarily due to its 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 in 2005.



Depreciation and amortization for 2006 increased compared to the prior year due primarily to additional amortization as a result of the Reilly acquisition.



Selling, general and administrative expense increased by $7.6
million as compared to the prior period primarily due to $3.0 million for the buyout of the Saratoga advisory services contract and $2.8 million of additional charges related to a pension curtailment and a deferred compensation plan in 2006.



Interest expense increased $8.5 million due primarily to $14.4
million of call premiums, write-off of deferred financing costs and consent fees related to Koppers Holdings Inc.s initial public offering in February 2006, which more than offset a reduction in interest expense related to the repayment of
$101.7 million of the Senior Secured Notes from the proceeds of the initial public offering.



Income taxes for the year ended December 31, 2006 were $3.1 million lower when compared to the prior year period due primarily to the tax benefit of non-conventional fuel tax credits recorded in 2006. Our
effective income tax rate for the year ended December 31, 2006 was 29.3 percent as compared to the prior year effective income tax rate of 38.7 percent. Our effective income tax rate decreased due primarily to the effect of a benefit recorded
for non-conventional fuel tax credits in the current year period and a non-deductible penalty in New Zealand in the prior year period, which was partially offset by greater tax expense in China (caused by a partial phase-out of a tax holiday there)
in the current year period and greater U.S. tax expense on a larger amount of repatriated earnings in the current year period.

North American CM&C
sales increased by 19 percent due primarily to $55.8 million of sales from the Reilly acquisition, $3.3 million of higher freight costs, and price increases (driven primarily by higher raw material costs) of $18.3 million for carbon pitch and
phthalic anhydride, partially offset by volume reductions of $21.0 million for carbon pitch, refined tar, naphthalene, and roofing products. Operating profit as a percentage of net sales increased to 9.2 percent from 7.7 percent between periods due
primarily to higher prices for phthalic anhydride and the synergies realized from the Reilly acquisition, which more than offset $1.5 million of allocated expense for the buyout of the Saratoga advisory services contract.



Australasian CM&C sales increased by 18 percent due primarily to $21.0
million of price increases for carbon pitch, carbon black, carbon black feedstock, and naphthalene. Operating profit as a percentage of net sales decreased to 11.9 percent from 14.4 percent between periods primarily due to $1.2 million of legal and
environmental charges, significantly higher raw material costs, and lower volumes of naphthalene.



European CM&C sales increased by 24 percent due primarily to $6.8 million of increased sales from a full year of the Lambson acquisition, $4.2 million of
favorable foreign exchange rate impact, and $21.9 million of price increases for carbon pitch, carbon black feedstock and naphthalene. Operating profit as a percentage of net sales increased to 5.9 percent from 5.2 percent between periods primarily
due to higher prices for carbon black feedstock and naphthalene.



Cash Flow



Net cash provided by operating activities was $65.7 million

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 its financial obligations, including payments of principal, interest and other amounts on the Koppers Holdings 97/8 percent Senior Discount Notes due 2014 (the Senior Discount Notes). The terms of Koppers Inc.s senior secured 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 senior secured 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 senior secured credit facility requires compliance with all financial covenants and availability of at least $15.0 million under the revolving credit facility after giving effect to any proposed dividend.

availability under the senior secured credit facility would restrict Koppers Inc.s ability to pay dividends. As of December 31, 2007, dividends available to
be declared based on covenant restrictions under the Senior Secured Notes amounted to $133.6 million.



Liquidity



The Koppers Inc. senior secured credit facility agreement, as amended, provides for a revolving credit facility of up to $125.0 million and term loans of $31.6
million at variable rates. The senior secured credit facility expires in December 2009. Amounts outstanding under the senior secured credit agreement are secured by a first priority lien on substantially all of Koppers Inc.s assets, including
the assets of certain significant subsidiaries. Revolving credit availability is calculated based on receivables and inventory as well as the attainment of certain financial ratios. The revolving credit facility contains certain covenants that limit
capital expenditures by Koppers Inc. and restrict our ability to incur additional indebtedness, create liens on our 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, 2007, we had $94.3 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, 2007,
$18.7 million of commitments were utilized by outstanding letters of credit. In addition, as of December 31, 2007, we had outstanding term loans of $31.6 million under the credit facility.



The following table summarizes Koppers estimated liquidity as of December 31, 2007
(dollars in millions):



|                                                      |  |   |

Our estimated liquidity was
$85.6 million at December 31, 2006. The increase in estimated liquidity from that date is due primarily to an increase in availability under our senior secured credit facility.



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. We believe that our cash flow from operations
and available borrowings under the senior secured 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 Koppers Arch for the three years ended December 31, 2007 have not been restated in the consolidated statement of cash flows. Excluding cash proceeds from the sale of Koppers Arch, net cash outflows of Koppers
Arch totaled $(1.1) million, $(0.7) million and $(0.5) million for the years ended December 31, 2007, 2006 and 2005, respectively. 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.

|--- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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 $4.2 million in 2008. 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 17 of the Consolidated Financial Statements.



In 2008, we expect
to retire from service one of our owned vessels used to transport carbon material products and raw materials. In connection with this retirement, we may be liable to fund the severance benefits for certain members of the vessels crew, who are
not our employees, under a contractual arrangement with the vessels operator. There are a number of uncertainties regarding our obligation to fund such benefits and the extent of the liability, if any, under the contractual arrangement. In
connection with the owned vessels retirement, we expect to enter into a time charter in 2008 to lease a replacement vessel for a term of up to seven years (including renewal periods). The incremental contractual obligation with respect to the
replacement vessel is approximately $5.0 million per year.

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, shall not be less than 1.05 to 1.0. The fixed charge
coverage ratio at December 31, 2007 was 2.65 to 1.0.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The total leverage ratio, calculated as of the end of each fiscal quarter for the four fiscal quarters then ended, shall not exceed the ratios set forth below for the periods
as specified in the table below. The total leverage ratio at December 31, 2007 was 1.77 to 1.0.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|Fiscal Quarters Ended                 |  | Ratio     
|August 15, 2005 through June 30, 2008 |  | 5.0 to 1.0
|June 30, 2008 and thereafter          |  | 4.5 to 1.0



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



At December 31, 2007, Koppers Inc. had $218.3 million outstanding of Senior Secured Notes (excluding adjustment for related interest rate swap). The Senior
Secured Notes include customary covenants that restrict, among other things, the 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

##### Table of Contents

subsidiaries as of December 31, 2007 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, 2007:

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, 2007. 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, 2007 (there 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 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., Koppers Delaware, Inc., Koppers Redemption, Inc., 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, 2007, 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 is 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, 2007 would have to increase 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



Non-Conventional Fuel Tax Credits



We earn non-conventional fuel tax credits as a result of the production and sale of
coke and coke gas at our facility in Monessen, Pennsylvania. Until December 2006, federal tax law contained a phase-out provision that reduced or eliminated the non-conventional fuel tax credit if the reference



41

##### Table of Contents

price of oil was within (or exceeded) a phase-out range. The application of the phase-out provision, however, was revised to no longer apply to facilities
producing coke or coke gas otherwise eligible for the credit by the Tax Relief and Health Care Act of 2006, which was passed by Congress and signed into law by the President in December 2006. The recognition of non-conventional fuel tax credits
reduced our income tax expense by $5.3 million in 2007 and $5.2 million in 2006.



Under current tax law, the non-conventional fuel tax credit is now part of the general business credit. As such, to the extent the credits are not used in the tax year they are generated, the credits may be carried back one year and carried
forward 20 years. The non-conventional fuel tax credit provisions of the Internal Revenue Code applicable to products produced at our coke facility expire at the end of 2009.



Interest Rate Swap



In January 2004, Koppers Inc. entered into an interest rate swap agreement for $50 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 97/8 percent 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, 2007, 2006 and 2005 was to increase (decrease) interest expense by $0.5 million, $0.3 million and $(0.5) million, respectively. The fair value of the swap agreement
at December 31, 2007 was a liability of approximately $0.5 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, 2007, 2006 and 2005, exchange rate fluctuations resulted in an increase (decrease) to comprehensive income of $11.0
million, $10.3 million and $(8.3) 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 $0.4 million, $(0.8) million and $0.3 million for the years ended December 31, 2007, 2006 and 2005, 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



42



---

##### Table of Contents

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 (excluding
furnace coke) 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 51 percent of the FIFO inventory value at
December 31, 2007 and 2006.



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. 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, 2007 our balance sheet included $62.9 million of deferred tax assets. We have determined
that a valuation allowance of $7.1 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



43



---

##### Table of Contents

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, 2007 and 2006. 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 a liability
of $0.5 million at December 31, 2007.



At December 31, 2007 we
had $168.4 million of fixed rate debt and $102.9 million of variable rate debt, and at December 31, 2006, we had $168.4 million of fixed rate debt and $156.0 million of variable rate debt (for both years, including the swap). Our ratio of
variable rate debt to fixed rate debt at December 31, 2007, including the interest rate swap referred to above, was approximately 38 percent, reflecting a decrease in the ratio from 48 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, 2007 and
2006 would have increased the unrealized fair market value of the fixed rate debt by approximately $10.1 million in both years. The earnings and cash flows for the next year assuming a one percentage point increase in interest rates would decrease
approximately $1.0 million, holding other variables constant. With respect to the interest rate swap, a ten percent decrease in interest rates at December 31, 2007 would have decreased the unrealized fair market value of the interest rate swap
by approximately $0.9 million to an asset of $0.4 million. A ten percent increase in interest rates at December 31, 2007 would have increased the unrealized fair market value of the interest rate swap by approximately $0.9 million to a
liability of $1.4 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, 2007 and 2006, would be reductions of approximately $2.5 million and $1.7 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, 2007. 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, 2007.

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, 2007 and 2006,
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, 2007. 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. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis for our opinion.



In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Koppers Inc. and subsidiaries at December 31, 2007 and 2006, and the
consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2007, 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 4 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).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).

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, carbon black
feedstock and furnace coke. 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 is used in the production of rubber tires. Furnace coke is used in the production of steel.



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, 2007. 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 senior
secured 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 revolving 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 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 loss in stockholders equity. Currency
translation gains released to income totaled $2.8 million in 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 $0.4 million, $(0.8) million and $0.3 million for the years ended December 31, 2007, 2006 and 2005, 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. 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, 2007, 2006 and 2005 amounted to $111.1 million, $113.0 million and $100.9 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 2007, $2.5 million in 2006 and $2.8 million in 2005.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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.



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 $0.2 million and $0.3 million as of December 31, 2007 and 2006, respectively.



InventoriesInventories are carried at lower of cost or
market on a worldwide basis. In the U.S., inventory cost (excluding furnace coke and 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 51 percent of the FIFO
inventory value at December 31, 2007 and 2006.



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 2007 and 2006 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 2007 and 2006, the Company reversed $1.7 million and $1.5 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, 2007 and 2006 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, 2007 was an increase in interest expense of approximately $0.5 million and for the year ended
December 31, 2006 was an increase in interest expense of approximately $0.3 million. 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, 2007 and 2006 was a liability of $0.5 million and $2.4 million, respectively, 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.



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, 2007 and 2006:



|                                                               |  |                       |      |   |      |   |      |

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 8. Employees of Koppers Inc. participate in these plans
and receive common stock of Koppers Holdings Inc. On January 1, 2006, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 123 (Revised 2004), Share-Based Payments(SFAS 123(R)). SFAS
123(R) requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement as compensation cost based on the grant date fair value of the award. The Company has elected the modified
prospective application for adoption and the prior period financial statements have not been restated. In accordance with SFAS 123(R), the Company recognizes stock-based compensation cost for its employees that participate in the plan. Upon vesting
of the stock award and issuance of the shares by Koppers Holdings Inc., the Company records a capital contribution from Koppers Holdings Inc.



ReclassificationsCertain amounts in the prior years consolidated financial statements have been reclassified to conform to the
current year presentation, including the reclassification of $6.1 million from accounts receivable to other current assets for 2006.



3.    New Accounting Guidance



In December 2007, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standard No. 160, Noncontrolling
Interests in Consolidated Financial Statements (SFAS 160). 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

##### Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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. We are currently evaluating the impact of adopting SFAS 160 on our financial statements.



In February 2007, the FASB issued SFAS 159, The Fair Value Option for Financial Assets and Financial Liabilities. SFAS 159 allows companies to elect to
measure many financial assets and financial liabilities at fair value (the fair value option). The election is made on an instrument-by-instrument basis and is irrevocable. If the fair value option is elected for an instrument, SFAS 159
specifies that all subsequent changes in fair value for that instrument must be reported in earnings. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company has elected not to adopt the provisions of SFAS 159.



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-financial assets and liabilities. The adoption of SFAS 157 is not expected to have a material impact on the Company.



4.    Accounting Changes



In July 2006, the FASB issued FASB Interpretation No. 48, Accounting for
Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109 (FIN 48). FIN 48 prescribes a comprehensive model for how a company should recognize, measure, present and disclose in its financial statements uncertain
tax positions that a company has taken or expects to take on a tax return. The Company adopted FIN 48 effective January 1, 2007 and no impact to opening retained deficit occurred as a result of adoption.



In June 2006, the FASBs Emerging Issues Task Force (the EITF) issued
EITF 06-2, Accounting for Sabbatical Leave and Other Similar Benefits Pursuant to FASB Statement No. 43. EITF 06-2 requires accrual of sabbatical leave or other similar compensated absences over the requisite service period of the
employee. The Company adopted EITF 06-2 effective January 1, 2007 and recorded an increase to opening retained deficit of $0.1 million.



In October 2006, the FASB issued SFAS 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 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 underfunded status. The
accounting standard also requires that the postretirement projected benefit obligation measurement date be December 31 for all plans. The Company adopted the funded status recognition provisions of SFAS 158 effective December 31, 2006 and
recorded a charge to accumulated other comprehensive income of $7.0 million, net of tax. 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.

5.    Business Dispositions and Plant Closures



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

Business Dispositions and Due Diligence Costs



In June 2006, the
Company sold its specialty track products business and related assets located at the Companys facility in Alorton, Illinois for cash of $1.9 million. The Company recorded a loss on disposal, before tax, of $1.6 million which was recorded as a
component of cost of sales. Sales contributed by the business unit for the year ended December 31, 2006 and December 31, 2005 were $3.2 million and $8.1 million, respectively. Operating profit (loss), excluding the loss on disposal,
for the year ended December 31, 2006 and December 31, 2005 was $(0.6) million and $0.2 million, respectively.



In April 2006 the Company announced the cessation of operations at its wood treating facility in Superior, Wisconsin. The plant had reported revenues of
approximately $9.3 million in 2005. The majority of the sales and production were transferred to two of the Companys other existing wood treating facilities. The Company accrued $0.2 million of severance charges in 2006 related to the
termination of approximately 20 employees. Previously, the Company incurred an asset impairment charge of $0.6 million related to this facility in the fourth quarter of 2005.



During 2005 the Company incurred charges of $0.8 million related to the closure of the Companys wood treating facility in
Montgomery, Alabama in September 2005. Of this amount, $0.3 million was for impairment, $0.3 million was for accelerated depreciation of fixed assets and $0.2 million was for severance charges. Additional costs related to the closure of the
Montgomery facility totaled $0.9 million in 2006.



The Company has also
closed other facilities in recent years, including its wood products plants in Thornton, Australia in 2006 and Hume, Australia in 2005. In the course of preparing the underlying land at both locations for sale during 2007 and 2006, soil and
groundwater contamination was discovered while performing environmental assessments. Total environmental charges related to the Hume and Thornton properties were $2.1 million and $1.2 million for the year ended December 31, 2007 and 2006,
respectively.

Reilly Acquisition



On April 28, 2006 the Company acquired certain assets of Reilly Industries, Inc.s (Reilly) carbon materials business. The purchased assets
consist primarily of inventories, customer sales contracts, raw material supply contracts, rail car leases, pitch melting assets and a non-compete agreement. The Company has integrated the additional tar distillation production at its existing
facilities in the U.S. Results of operations for the year ended December 31, 2006, included the business acquired from Reilly from the date of acquisition. Net sales from the date of acquisition to December 31, 2006 totaled $55.8 million.



The aggregate purchase price was $45.1 million which was primarily
funded by a $40.0 million term loan with an existing bank group and cash. The aggregate purchase price also includes $0.2 million of transaction costs. The following table is a summary of the allocated purchase price to estimated fair values of the
assets acquired and liabilities assumed at the date of acquisition. Independent appraisals were obtained to determine the fair value of the identifiable intangible assets subject to amortization.

Lambson acquisition



In the second quarter of 2005, the Companys subsidiary located in the United Kingdom purchased the specialty chemical business
and certain related assets of Lambson Speciality Chemicals Limited (Lambson). The purchase price was approximately $10.6 million plus contingent consideration based on earnings of the business for two years subsequent to the acquisition.
The purchased assets consist primarily of certain assets related to production (excluding land) totaling $6.3 million and customer contracts and a non-compete agreement totaling $4.9 million. Additionally, approximately $0.6 million of liabilities
were assumed. The customer contracts and non-compete agreement are being amortized over a five-year and a three-year period, respectively. In 2007, the Company reversed $1.0 million of contingent purchase price consideration and reduced the cost
basis of property, plant and equipment by $0.6 million and intangible assets by $0.4 million.

8.    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.



On March 22, 2007, the Koppers Holdings Inc. board of directors granted 33,877 restricted stock units and 69,800 performance
stock units to certain employee participants (collectively, the stock units). The restricted stock units will vest ratably in March 2008, 2009 and 2010, assuming continued employment by the participant. For certain participants who
currently have unvested restricted stock units from a prior grant, vesting of the March 2007 restricted stock award will occur at the end of a three-year service period. The performance stock units will vest upon the attainment of the applicable
performance objective at the end of a three-year measurement period ending on December 31, 2009. The applicable performance objective is based upon a three-year cumulative value creation calculation commencing January 1, 2007. 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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 of Koppers Holdings Inc. 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 of Koppers Holdings Inc.



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 Koppers Holdings Inc. common stock on the date of grant.



The following table shows a summary of the performance stock units as of December 31, 2007:

On May 8, 2007 (the
grant date), Koppers Holdings Inc. granted 60,200 nonqualified stock options to certain employee participants which vest and become exercisable upon the completion of a three-year service period commencing on the grant date. The stock
options have a term of 10 years. In the event of termination of employment, all unvested stock options shall terminate and cease to be outstanding, except to the extent specifically authorized by the plan administrator. 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:

The dividend yield is based on Koppers Holdings Inc.s current and prospective dividend rate which
calculates a continuous dividend yield based upon the market price of the underlying common stock. The expected life in years is based on the simplified method permitted under Securities and Exchange Commission Staff Accounting Bulletin No. 107
which 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 Koppers Holdings Inc. 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. At December 31, 2007 consolidated retained earnings of the Company included approximately $45.6 million of undistributed earnings
from these investments.



Non-conventional Fuel Tax Credits



The Company earns non-conventional fuel tax credits as a result of the
production and sale of coke and coke gas at its 95 percent-owned facility in Monessen, Pennsylvania. Until December 2006,

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



federal tax law contained a phase-out provision that reduced or eliminated the non-conventional fuel tax credit if the reference price of oil was within (or exceeded)
a phase-out range. The application of the phase-out provision, however, was revised to no longer apply to facilities producing coke or coke gas otherwise eligible for the credit by the Tax Relief and Health Care Act of 2006, which was passed by
Congress and signed into law by the President in December 2006. This revision applied to coke or coke gas produced and sold after December 31, 2005, allowing the Company to earn tax credits for the entire 2006 year without having the credits be
subject to the phase-out. The Company recognized non-conventional fuel tax credits of $5.3 million and $5.2 million in 2007 and 2006, respectively.



Under current tax law, the non-conventional fuel tax credit is now part of the general business credit. As such, to the extent the credits are not used in the tax
year they are generated, the credits may be carried back one year and carried forward 20 years. The non-conventional fuel tax credit provisions of the Internal Revenue Code applicable to products produced at our coke facility expire at the end of
2009.



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, 2007, 2006 and 2005 were approximately $0.6 million, $0.3
million and $1.0 million, respectively. The tax holiday will expire on January 1, 2009.



Chinas government approved significant tax reform in 2007. Under this new law, Chinas dual tax system for domestic enterprises and foreign investment enterprises was effectively replaced by a unified system.
Transition rules under Chinas new tax law permit the Companys 60 percent-owned joint venture to effectively utilize the tax benefits that remain under its tax holiday through 2008.



Taxes Excluded from Net Income



The amount of income tax provision included in comprehensive income but excluded from
net income relating to adjustments to reflect the unfunded status of employee post-retirement benefit plans is $5.0 million and $0.1 million in 2007 and 2006, respectively, and to reflect minimum pension liabilities for 2005 was $1.7 million.



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 for 2007 and 2006 was $1.2 million and $0.4 million, respectively.



Deferred Tax Assets and Liabilities



Deferred income taxes reflect the net tax effects of temporary differences between the
carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

The Company adopted the provisions of FIN 48, Accounting for Uncertainty in Income Taxes, on
January 1, 2007. 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, 2007, the total amount of unrecognized tax benefits that, if
recognized, would affect the effective tax rate, was approximately $2.3 million. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

The Company recognizes interest
expense and any related penalties from uncertain tax positions in income tax expense. For each year ended December 31, 2007, 2006 and 2005, the Company recognized less than $0.1 million in interest and penalties. As of December 31,
2007 and 2006, the Company had accrued approximately $0.4 million and $0.4 million, respectively, for interest and penalties.



10.    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, carbon
black feedstock and furnace coke. 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 is used in the production of rubber tires. Furnace coke is used in the production of steel.



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.

Senior Secured Revolving Credit Facility & Term Loans



The Koppers Inc. senior secured credit facility agreement, as amended, provides for a
revolving credit facility of up to $125.0 million and term loans of $31.6 million at variable rates. The loans are secured by a first priority lien on substantially all of Koppers Inc.s assets, including the assets of certain significant
subsidiaries. Revolving credit availability is calculated based on receivables and inventory as well as the attainment of certain financial ratios. 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, 2007, the Company
had $94.3 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, 2007, $18.7 million of commitments were utilized by
outstanding letters of credit. In addition, as of December 31, 2007, the Company had outstanding term loans of $31.6 million under the credit facility.



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.



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 long-term liabilities and 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, 2007 and December 31, 2006, the impact of the interest rate swap decreased the carrying value of the Senior Secured Notes by $0.5 million and $2.4
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.

17.    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 two 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.



In November 2006, the Companys board of directors approved a freeze of the Companys U.S. qualified and corresponding non-qualified defined benefit
pension plans for salaried employees. Effective December 31, 2006, salaried employees no longer accrue additional years of service or recognize future increases in compensation under the existing defined benefit pension plans 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 the fourth quarter of 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. On August 8, 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 $3.6 million, $1.7 million and $1.6
million for the years ended December 31, 2007, 2006 and 2005, 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 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.

for pension plans and $1.2 million for other benefit plans.



Projected Benefit Payments



Benefit payments for
pension benefits, which are primarily funded by the pension plan assets, and other benefits, which are funded by general corporate assets and reflecting future expected service as appropriate, are expected to be paid 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.



The weighted average asset allocation for the Companys pension plans at
December 31 by asset category is as follows:

Health Care Cost Trend
Rates



The 2007 initial health care cost trend rate is assumed
to be twelve 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 this plan was $7.2 million in 2007, $4.9 million in 2006 and $5.4 million in 2005.



18.    Common Stock and Senior Convertible Preferred Stock



There was one share of Koppers Inc. outstanding at December 31, 2006, 2005 and
2004.



Receivable from Director for Purchase of Common Stock



In October 1999, a Director of the Company purchased 220,065
shares of common stock of the Company for $0.9 million. Of this amount, 140,467 of the shares were financed through an interest-free loan from the Company in the amount of $0.6 million due in 2009. This receivable is separately classified in
stockholders equity. In the event that the Director no longer serves on the board of directors, the loan must be repaid.

Cash and short-term investmentsThe carrying amount approximates fair value because of the short maturity of those instruments.



Investments and other assetsRepresents the broker-quoted cash surrender
value on universal life insurance policies.



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.



20.    Commitments and Contingent Liabilities



The Company and its subsidiaries are involved in litigation and various proceedings relating to environmental laws and regulations and antitrust, toxic tort,
product liability and other matters. Certain of these matters are discussed below. The ultimate resolution of these contingencies could, individually or in the aggregate, be material to the consolidated financial statements.



Legal Proceedings



Litigation.    In January 2007, Timtech Chemicals
Limited (Timtech) filed a Statement of Claim in the High Court of New Zealand against a number of corporate and individual defendants, including Koppers Arch Wood Protection (NZ) Limited, Koppers Arch Investments Pty. Limited, Koppers
Australia Pty Limited and a number of other corporate and individual defendants. The Statement of Claim alleges various causes of action against the defendants including claims related to breaches of the New Zealand Commerce Act of 1986. Timtech is
seeking damages against all defendants in the amount of $3.9 million plus exemplary damages and pre-judgment interest in an unspecified amount.

Until July 5, 2007, Koppers Arch Wood Protection (NZ) Limited was a majority-owned subsidiary of Koppers Arch Investments Pty Limited, which was an Australian
joint venture 51 percent of which was owned by World-Wide Ventures Corporation (an indirect subsidiary of the Company) and 49 percent of which was owned by Hickson Nederland BV, an affiliate of Arch Chemicals, Inc. Koppers Arch Wood Protection (NZ)
Limited manufactured and marketed wood preservative products throughout New Zealand. The Company sold its 51 percent interest in Koppers Arch Investments Pty. Limited and its subsidiaries on July 5, 2007 (see Note 5) to Arch Chemicals, Inc. and
has provided an indemnity to the buyer for its share of liabilities, if any, arising from certain litigation and claims including the Timtech litigation and claims arising from the New Zealand Commerce Commission and the Australian Competition and
Consumer Commission investigations.



Although the case will be vigorously
defended, 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. It is possible that other civil claims could be filed against the
Company arising from alleged breaches of New Zealand and Australian competition laws. Such other claims, if filed and resolved unfavorably, could have a material adverse effect on the business, financial condition, cash flows and results of
operations of the Company.



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 93 plaintiffs in 50 cases pending as of December 31, 2007 as compared to 72 plaintiffs in 36 cases as of December 31, 2006. As of December 31, 2007, there are a total of 43
cases filed in state court in Pennsylvania, one case each filed in state courts in California, Tennessee, Oregon and Texas, two cases each filed in an Indiana state court and one case filed in the United States District Court for the Eastern
District of Tennessee.



The plaintiffs in all 50 pending cases seek to
recover compensatory damages, while plaintiffs in 40 cases also seek to recover punitive damages. The plaintiffs in the 43 cases filed in Pennsylvania state court seek unspecified damages in excess of the courts minimum arbitration
jurisdictional limit of $25,000. The plaintiffs in the two cases filed in Indiana state court and the one case filed in the United States District Court for the Eastern District of Tennessee also seek unspecified damages. The plaintiffs in the
California state court case seek damages in excess of $2.0 million, while the plaintiff in the Oregon state court 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
plaintiffs in one Texas state court case seek damages that are not in excess of $10.0 million. The plaintiffs in the remaining Texas state court case have agreed to dismiss their claims against Koppers Inc. pending execution of final settlement and
release documents.



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 lawsuits in which the plaintiffs allege exposure to benzene, benzene
containing products and other products, including oils and solvents sold by Koppers Inc. There are 72 plaintiffs in 10 cases pending as of December 31, 2007 as compared to 65 plaintiffs in 13 cases as of December 31, 2006. Most of these
cases also involve numerous other defendants in addition to Koppers Inc. 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 three sets of state court cases in Texas involving approximately 150 plaintiffs who allegedly have 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) and property damage resulting from toxic contamination from exposure to wood preservative chemicals used at the Somerville, Texas wood treatment plant. Koppers Inc. acquired the plant in 1995. The plant was operated at this
site under different ownership from 1905 to 1995.



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. Koppers Inc. was served with two of the cases in September 2006 and October 2006. Koppers Inc. was joined in the third case (which
already had been pending against the BNSF) in May 2007. The September 2006 case was most recently amended in May, 2007 and identified approximately 44 plaintiffs (five of whom have claims against only the BNSF under the Federal Employees Liability
Act). In December, 2007, these plaintiffs had their claims severed into 29 separate lawsuits, 24 of which remain pending against Koppers Inc. The October 2006 case was amended in April, 2007 and identifies a total of 10 plaintiffs, four of whom have
claims against only the BNSF. The third case, which is the only one of the three cases filed in Tarrant County, Texas, identifies a total of 93 plaintiffs, of whom 92 are intervenors. Discovery is proceeding in these cases.



Koppers Inc. was named as a defendant in a putative class action lawsuit which sought
the establishment of a medical monitoring program and the costs of periodic health screening and diagnostic testing for a class of approximately 7,500 people who have lived or currently live in Somerville, but who have not experienced any diseases.
The case was filed in the United States District Court for the Western District of Pennsylvania in October 2007. Plaintiffs allege that they have been exposed to harmful levels of various toxic chemicals from the Somerville wood treatment plant.
Plaintiffs sought unspecified damages, equitable relief, attorneys fees and costs. In November 2007, the plaintiffs voluntarily dismissed the case.



An additional complaint was filed in the District Court of Burleson County, Texas in October 2007. The complaint is a putative class action filed on behalf of
current and former residents of Somerville, Texas who live or lived within a one mile radius of the Somerville wood treatment plant. Plaintiffs estimate the putative class to number in excess of 2,500 people. Koppers Inc. and the Burlington Northern
Santa Fe Railway Company are defendants. The complaint seeks certification of a class action, compensatory damages in an unspecified amount, relocation expenses, injunctive relief,

punitive damages in an unspecified amount, the costs of developing a notice plan to notify members of the putative class and attorneys fees. The complaints
contain counts relating to private nuisance, trespass, negligence, negligence per se and gross negligence arising from alleged emissions of toxic chemicals from the Somerville plant. Plaintiffs also filed an application for a temporary injunction
seeking, among other things, temporary injunctive relief from alleged further releases of chemicals from the Somerville plant, the temporary relocation of all class members and reimbursement for certain personal and relocation expenses. On
October 26, 2007, Koppers Inc. removed this case from the District Court of Burleson County, Texas, to the United States District Court for the Western District of Texas, Austin Division. On January 31, 2008, the Court dismissed the case
without prejudice.



Koppers Inc. has been named as a defendant in a
lawsuit filed in the Circuit Court of Cook County, Illinois, by approximately 150 current and former residents of Somerville who claim that they have developed personal injuries, illnesses and wrongful deaths as a result of exposure to chemicals and
contaminants which they allege have emanated from the Somerville plant. Plaintiffs assert claims for negligence, trespass and willful and wanton conduct against the BNSF and Koppers Inc., and claims for negligence and strict products liability
against several manufacturers and suppliers of a wood preservative to the plant. Plaintiffs seek compensatory damages in excess of the courts jurisdictional limit and unspecified punitive damages and costs. On December 6, 2007, Koppers
Inc. filed a notice of removal removing this case from the Circuit Court of Cook County, Illinois, to the United States District Court for the Northern District of Illinois, Eastern Division. On January 4, 2008, plaintiffs filed a motion to
remand the case to state court. The parties are awaiting the United States District Courts ruling on plaintiffs motion to remand.



Koppers Inc. also has been named as a defendant in six cases that were filed on December 27, 2007, in
the 21stand 335thJudicial Districts in Burleson County, Texas. These cases
collectively name approximately 544 plaintiffs. The personal injury claims primarily are restatements of claims that had been previously asserted in a case filed in the United States District Court for the Western District of Texas, Austin Division
which was voluntarily dismissed in November 2006. Compensatory and punitive damages have been requested in this newly filed complaint.



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. Other than for cases in which a verdict has been rendered (see GrenadaFederal Court Cases below), the Company has not provided a reserve for these lawsuits because, at this time, it cannot

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 the 12 plaintiffs whose claims were not dismissed are still pending. The 12 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 court ordered that the claims of the 12 remaining Beck plaintiffs must be tried separately.



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. The Company accrued Koppers Inc.s portion of the verdict in the first quarter of 2006. Koppers Inc.
has appealed the judgment entered against it to the United States Court of Appeals for the Fifth Circuit. Oral arguments were held before the Court of Appeals on January 28, 2008. The Court of Appeals has not issued its decision on the appeal.
The remaining 11 trials have been stayed pending the appeal by Koppers Inc. of the judgment entered in the first case.



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 12 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. Until the resolution of the
motions to dismiss, discovery in the four non-Grenada County cases will remain stayed.

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, 43 have been dismissed to date. Motions for summary judgment on
behalf of defendants based on the Mississippi statute of limitations have been filed in 40 of the remaining cases. Motions to dismiss are pending in 11 additional cases for want of prosecution or failure to comply with court
orders. Discovery is proceeding in the remaining 21 cases in the Grenada County litigation.

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. Expense for 2005 consisted of $2.6 million for
estimated penalties and costs related to the NZCC antitrust litigation. Cash expenditures in 2005 related to the settlement of a breach of contract case related to the sale of vineyard trellises by a subsidiary of Koppers Australia.



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

KOPPERS INC.



NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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 unconditionally guaranteed Beazer Easts
performance of the Indemnity pursuant to a guarantee (the Guarantee). Beazer Limited became a wholly owned indirect subsidiary of Hanson PLC in 1991. In 1998, Hanson PLC 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. In 2007, Hanson PLC was acquired by 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.



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



86

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Resource Conservation and Recovery Act (RCRA)), substantially 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 $13.4 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 are currently in discussions 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 its having
significant additional negative net worth.



Domestic Environmental
Matters.    Koppers Inc. was named as a potentially responsible party (a PRP) at a CERCLA Superfund site in Amelia, Louisiana in May 2007. A PRP group has been formed; however, the Companys cost
sharing responsibility, if any, has not been determined. Koppers Inc. was named as a PRP at a CERCLA Superfund site in Calvert City, Kentucky in November 2006 and has subsequently joined the PRP group. The Companys cost sharing responsibility
as a member of the PRP group is currently calculated at less than two percent, but is subject to adjustment based on a final allocation agreement to be negotiated among the PRPs. The Company has provided a reserve for these and other CERCLA
sites totaling $0.2 million as of December 31, 2007.



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 results of the site investigation
were received in the fourth quarter of 2006 and were reviewed with IEPA in July 2007. The Company and Beazer East have agreed to enter into the Illinois Voluntary Remediation Program in relation to the owned portion of this site. Remediation on a
leased portion of this site is still under discussion. The Company and Beazer East have engaged consultants to assist the Company in preparing a remediation strategy and an estimate of potential costs. The Company has provided a reserve for this
matter totaling $1.6 million as of December 31, 2007.



In October
1996, Koppers Inc. received a Clean Water Act (CWA) information request from the EPA. This information request asked for comprehensive information on discharge permits, applications for discharge permits, discharge monitoring reports and the
analytical data in support of the reports and applications. The EPA alleged that Koppers Inc. violated various provisions of the CWA. Koppers Inc. subsequently entered into a Consent Decree and agreed, among other things, to a $2.9 million

settlement payment. In 2005, Koppers Inc. filed to terminate the Consent Decree at which time the EPA informed Koppers Inc. that it will seek civil penalties for any
CWA violations from 2001 to 2005 concurrent with the termination of the Consent Decree. Koppers Inc. and the EPA have agreed to a settlement of $0.5 million for such civil penalties and the Company has provided a reserve for the amount of the
settlement.



In August 2005, Koppers Inc. received a CWA information
request from Region 4 of the EPA. Region 4 encompasses six of Koppers Inc.s facilities, of which four are currently operating. This information request asked for comprehensive information on discharge permits, applications for discharge
permits, discharge monitoring reports and the analytical data in support of the reports and applications as well as engineering studies and a limited number of specific inspection records. Koppers Inc. subsequently provided the EPA with certain
information to assist it in its review. In December 2006, Koppers Inc. received information from Region 4 regarding alleged violations by Koppers Inc. The Company will settle this matter in connection with the CWA information request discussed
above.



In May 2007, Koppers Inc. received a separate information request
from Region 4 of the EPA on all releases of hazardous materials from its facilities in Region 4 for a five-year period. Koppers Inc. has provided the requested information.



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, have provided a reserve of $1.6 million as of December 31, 2007. The consent order
will likely provide for stipulated penalties for any additional exceedances that occur between the date of the execution of the consent order and the date of completion of such improvements.



In June 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 is expected to
expire in January 2009. A failure on the Companys part to comply with the terms of the compliance agreement could lead to significant costs and sanctions, including the potential for suspension or debarment from government contracts. A
suspension or debarment from government contracts would have a material adverse effect on the Companys business, financial condition, cash flows and results of operations.



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 $1.9 million and the owner of the adjacent
property will contribute $5.9 million toward remediation of the property. Subject to the approval of a remediation action plan by

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



local environmental authorities, 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 property will transfer to the Company. The Company has reserved its expected total remediation costs of $1.9 million at December 31, 2007.



Other Australian environmental matters include soil and groundwater
remediation at two former wood products facilities in Australia which are being prepared for marketing and 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 $0.7 million and $2.2 million. The Company is currently working with local environmental authorities to determine the preferred
method of remediation.



With respect to the second facility in Thornton,
Australia, an environmental assessment was completed in the second quarter of 2007 which indicated areas of soil contamination which the Company may remediate in preparation for sale. The estimated soil remediation costs range between $1.7 million
and $3.4 million. The Company has reserved approximately $2.7 million for remediation costs at these sites which represents its best estimate of groundwater and remaining soil remediation.



Soil and groundwater contamination has been detected at the Companys facility in
Kurnell, Australia. Contaminated soil has been delineated and options for treatment or disposal are being reviewed. Contamination in shallow groundwater has been delineated and will be addressed through enhanced natural attenuation. The Company has
reserved $0.5 million for remediation at this 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Expense for 2005 included estimated soil remediation costs at the Companys tar distillation facility in
Newcastle, Australia and estimated settlement costs at the Clairton, Pennsylvania and Stickney, Illinois coal tar plants. Additional expenses related to waste disposal and remediation costs at plants in Australia and the United Kingdom were offset
by the reversal to profit of reserves in our Danish operations as the result of the completion of a waste disposal project.



Contingent Liabilities



In 2008, the Company expects to retire from service an owned vessel used to transport carbon material products and raw materials. In connection with this
retirement, the Company may be liable to fund the severance benefits for certain members of the vessels crew, who are not employees, under a contractual arrangement with the vessels operator. There are a number of uncertainties regarding
the obligation to fund such benefits and the extent of the liability, if any, under the contractual arrangement.



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.



21. Related Party Transactions



Schnader Harrison Segal & Lewis LLP provided counsel to the Company during
2007 and 2006. Clayton A. Sweeney, a Director and shareholder of the Company, is also counsel to Schnader Harrison Segal & Lewis LLP. During 2007 and 2006, the Company paid a total of $0.1 million each year in legal fees to this firm.



The Company had entered into a consulting agreement in 1999 with Robert
Cizik, a Director and shareholder of the Company, that 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 at a price of $4.27 per share.
Mr. Cizik purchased these shares in October 1999 by signing a promissory note to the Company for $0.6 million. The note, which is 70 percent collateralized by the value of the related shares and 30 percent by Mr. Ciziks personal
assets, is due in 2009, or immediately in the event Mr. Cizik is no longer Non-Executive Chairman of the board of directors. The shares were initially restricted, with a vesting period of five years; at December 31, 2003 all of the shares
were vested. Mr. Cizik has the right to require the Company to redeem the 140,467 shares at any time at the lower of cost or current fair market value; however, the disposition or transfer of the shares requires the related loan to be repaid
immediately.



On December 7, 2005, the board of directors of Koppers
Inc. (with Mr. Cizik abstaining) voted to authorize the termination of the Consulting Agreement. On December 23, 2005, Koppers Inc. and Mr. Cizik executed an agreement to terminate the Consulting Agreement, effective January 1,
2006. In connection with such termination, the Company and its subsidiary agreed to pay Mr. Cizik the sum of $0.6 million on December 31, 2005 and Mr. Cizik agreed to continue to serve as a director for at least two years.
Mr. Cizik will also remain as Non-Executive Chairman of Koppers Inc., but he will receive no additional compensation for such services. The termination of the Consulting Agreement will not affect the terms of Mr. Ciziks interest-free
loan or his stock ownership.



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 Koppers Holdings Inc.s initial public offering, and an affiliate of Saratoga Partners was paid a financial advisory services termination fee of $3.0 million in 2006.



22. 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.
