                            KOPPERS INDUSTRIES, INC.
 
        OFFER TO EXCHANGE ITS 9 7/8% SENIOR SUBORDINATED NOTES DUE 2007,
              WHICH HAVE BEEN REGISTERED UNDER THE SECURITIES ACT,
   FOR ITS 9 7/8% SENIOR SUBORDINATED NOTES DUE 2007, WHICH HAVE NOT BEEN SO
                                  REGISTERED.
                                 -------------
  THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON        ,
                             1998, UNLESS EXTENDED
                                 -------------
 
  Koppers Industries, Inc. and all of its subsidiaries (the "Company" or
"Koppers"), a Pennsylvania corporation, hereby offers, upon the terms and
subject to the conditions set forth in this Prospectus and the accompanying
Letter of Transmittal (which together constitute the "Exchange Offer"), to
exchange up to $175,000,000 aggregate principal amount of its new 9 7/8% Senior
Subordinated Notes due 2007 (the "New Notes"), which have been registered under
the Securities Act of 1933, as amended (the "Securities Act"), for a like
principal amount of its outstanding 9 7/8% Senior Subordinated Notes due 2007
(the "Old Notes"), which have not been so registered. The terms of the New
Notes are identical in all material respects to the Old Notes, except for
certain transfer restrictions relating to the Old Notes. The New Notes will
evidence the same indebtedness as the Old Notes and will be issued pursuant to,
and entitled to the benefits of, the same Indenture that governs the Old Notes
(the "Indenture"). As used herein, the term "Notes" means the Old Notes and the
New Notes, treated as a single class.
 
  The Company will accept for exchange any and all Old Notes validly tendered
and not withdrawn prior to 5:00 p.m., New York City time, on         , 1998
unless extended (as, so extended, the "Expiration Date"). Tenders of Old Notes
may be withdrawn at any time prior to the Expiration Date. The Exchange Offer
is not conditioned upon any minimum principal amount of Old Notes being
tendered for exchange pursuant to the Exchange Offer. The Exchange Offer is
subject to certain other customary conditions. See "The Exchange Offer."
 
  The Notes are redeemable at the option of the Company, in whole or in part,
at any time on or after December 1, 2002. The New Notes will be, and the Old
Notes currently are, unsecured obligations of the Company ranking pari passu
with all other unsecured and subordinated indebtedness of the Company.
 
  The holder of each Old Note accepted for exchange will receive a New Note
having a principal amount equal to that of the surrendered Old Note. The New
Notes will bear interest from the most recent date to which interest has been
paid on the Old Notes or, if no interest has been paid on the Old Notes, from
December 1, 1997. Old Notes accepted for exchange will cease to accrue interest
from and after the date of consummation of the Exchange Offer. Holders of Old
Notes accepted for exchange will not receive any payment in respect of accrued
interest on such Old Notes. Old Notes not tendered or not accepted for exchange
will continue to accrue interest from and after the date of consummation of the
Exchange Offer.
 
  The Old Notes were issued and sold on December 1, 1997 in a transaction
exempt from the registration requirements of the Securities Act and may not be
offered or sold in the United States unless so registered or pursuant to an
applicable exemption under the Securities Act. The New Notes are being offered
hereunder in order to satisfy certain obligations of the Company contained in
the Registration Rights Agreement (as defined). Based on interpretations by the
staff of the Securities and Exchange Commission (the "Commission") as set forth
in no-action letters issued to third parties, the Company believes that New
Notes issued pursuant to the Exchange Offer in exchange for Old Notes may be
offered for resale, resold and otherwise transferred by any holder thereof
(other than a holder that is an "affiliate" of the Company within the meaning
of Rule 405 under the Securities Act), without compliance with the registration
and prospectus delivery provisions of the Securities Act, provided that such
New Notes are acquired in the ordinary course of such holder's business and
such holder has no arrangement or understanding with any person to participate
in a distribution of such New Notes. However, the Company has not sought a no-
action letter with respect to the Exchange Offer and there can be no assurance
that the staff of the Commission would make a similar determination with
respect to the Exchange Offer. Each holder of Old Notes, other than a broker-
dealer, must acknowledge that it is not engaged in, and does not intend to
engage or participate in, a distribution of New Notes and has no arrangement or
understanding to participate in a distribution of New Notes. Each broker-dealer
that receives New Notes for its own account pursuant to the Exchange Offer must
acknowledge that it will deliver a prospectus in connection with any resale of
such New Notes. The Letter of Transmittal states that by so acknowledging and
by delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act. This Prospectus,
as it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of New Notes received in exchange for
Old Notes acquired by such broker-dealer as a result of market-making
activities or other trading activities. The Company has agreed that, ending on
the close of business on the 180th day following the Expiration Date (as
defined herein), it will make this Prospectus available to any broker-dealer
for use in connection with any such resale. See "Plan of Distribution."
 
  The Company will not receive any proceeds from the Exchange Offer. The
Company will pay all the expenses incident to the Exchange Offer. Tenders of
Old Notes pursuant to the Exchange Offer may be withdrawn at any time prior to
the Expiration Date. In the event the Company terminates the Exchange Offer and
does not accept for exchange any Old Notes, the Company will promptly return
the Old Notes to the holders thereof. See "The Exchange Offer."
 
  SEE "RISK FACTORS" WHICH BEGINS ON PAGE 16 OF THIS PROSPECTUS, FOR A
DESCRIPTION OF CERTAIN RISKS TO BE CONSIDERED BY HOLDERS WHO TENDER THEIR OLD
NOTES IN THIS EXCHANGE OFFER.
                                 -------------
 
THESE  SECURITIES HAVE NOT BEEN APPROVED  OR DISAPPROVED BY THE SECURITIES  AND
 EXCHANGE  COMMISSION   OR  ANY  STATE  SECURITIES  COMMISSION  NOR   HAS  THE
  SECURITIES  AND  EXCHANGE COMMISSION  OR  ANY STATE  SECURITIES  COMMISSION
   PASSED   UPON  THE  ACCURACY   OR  ADEQUACY   OF  THIS   PROSPECTUS.  ANY
    REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                          ENFORCEABILITY OF JUDGMENTS
 
  Koppers Australia, one of the Subsidiary Guarantors (as defined herein), is
a company limited by shares incorporated under the laws of certain States and
territories of the Commonwealth of Australia. Many of the directors and
executive officers of Koppers Australia (and certain of the experts named in
this Prospectus) are citizens or residents of jurisdictions other than the
United States. All or a substantial portion of the assets of such directors,
executive officers and experts residing outside of the United States and all
of the assets of Koppers Australia are or may be located outside of the United
States, primarily in Australia. As a result, it may not be possible to effect
service of process on such directors and executive officers, such experts or
on Koppers Australia in the United States or to enforce, collect or realize
upon, in the United States courts, judgments against such persons obtained in
United States courts and predicated upon civil liability under United States
securities laws. Koppers has been advised by their special Australian counsel,
Baker & McKenzie, that there is doubt as to the enforceability of civil
liabilities under United States securities laws in actions originating in
federal and state courts in Australia. Baker & McKenzie has also advised
Koppers, however, that subject to certain conditions, exceptions and time
limitations, Australian courts will enforce foreign (including United States)
judgments for liquidated amounts in civil matters, including (although there
is no express authority relating thereto) judgments for such amounts rendered
in civil actions under United States securities laws. Such counsel has further
advised Koppers that an Australian court may allow the enforcement of a
judgment to be effected in United States dollars if such court is satisfied
that this best expresses the relevant loss of a plaintiff, although no opinion
is expressed as to whether or not enforcement of any judgment against Koppers
Australia would be effected in any currency other than Australian dollars and,
if in Australian dollars, the date of determination of the applicable exchange
rate from United States dollars to Australian dollars. Koppers Australia has
appointed CT Corporation System as its agent for service of process in any
suit, action or proceeding with respect to, the Indenture, the Notes and the
Subsidiary Guarantees, brought under federal or state securities laws or
otherwise in any federal or state court located in the Borough of Manhattan,
The City of New York, State of New York, and have submitted to such
jurisdiction. CT Corporation System has agreed to accept such appointment
until one year from the date of issuance of the Notes and has agreed to
continue to serve in such capacity thereafter, provided that Koppers Australia
pays an annual renewal fee.

                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information, including the financial statements and notes thereto, appearing
elsewhere in this Prospectus. Unless otherwise noted herein, the information
contained in this Prospectus assumes the consummation of the Koppers Australia
Acquisition (as defined herein), which occurred on December 1, 1997 and
pursuant to which Koppers Australia Pty. Limited became a wholly-owned
subsidiary of Koppers Industries, Inc. Except where otherwise indicated,
"Koppers" means Koppers Industries, Inc. and all of its subsidiaries, and the
"Company" refers to Koppers and Koppers Australia (as defined herein). Except
where otherwise indicated, all conversions from Australian dollars to U.S.
dollars are performed using the conversion rate in effect on October 10, 1997,
which was $0.735.
 
                                  THE COMPANY
 
GENERAL
 
  The Company is a leading integrated producer of carbon compounds and treated
wood products for use in a variety of markets including the chemical, railroad,
aluminum and steel industries. The "Koppers" name has been associated with the
carbon compounds and wood treating businesses for over 70 years, and the
Company has a leading position in most of its markets. The Company operates 22
facilities in the United States and 14 in the South Pacific (primarily
Australia and New Zealand), and maintains indirect ownership interests in an
additional facility in the United States through its domestic joint venture KSA
(as defined herein) and in five facilities overseas through its joint venture
Tarconord A/S ("Tarconord"). On a pro forma basis the Company recorded net
sales and Adjusted EBITDA (as defined herein) of $717.6 million and $95.8
million, respectively, for the twelve months ended September 30, 1997. For the
same period, the Company's businesses, Carbon Materials & Chemicals, Railroad &
Utility Products, Coke Products and Koppers Australia Pty. Limited and its
subsidiaries ("Koppers Australia"), accounted for 34%, 35%, 14% and 17% of pro
forma net sales, respectively.
 
  Through its Carbon Materials & Chemicals division, Koppers is the largest
coal tar processor in North America. Koppers' Carbon Materials & Chemicals
division processes coal tar into a variety of intermediate products, including
carbon pitch, phthalic anhydride ("PAA") and creosote, which are basic
materials necessary in the production of aluminum, polyester resins and
plasticizers, and the pressure treatment of wood, respectively. Koppers'
Railroad & Utility Products division is the largest supplier of treated wood
products, such as railroad crossties and utility poles, to United States
railroads and the electric and telephone utility industries. Koppers' Coke
Products division converts coal into coke for sale to integrated steel
producers and foundries that use coke in the production of iron and steel.
 
  Products and services provided by Koppers Australia are similar to those
provided by Koppers. Koppers Australia is Australia's largest manufacturer of
carbon pitch, wood preservatives and treated wood products and it markets these
products, as well as carbon black, in Australia, New Zealand and other Pacific
Rim nations. Koppers Australia is the only coal tar distiller in Australia,
providing it with a significant competitive advantage in serving the Australian
aluminum smelting industry.
 
BUSINESS STRATEGY
 
  The Company's strategy includes: (i) improving productivity; (ii)
implementing additional cost reduction initiatives; (iii) developing, marketing
and selling new products; and (iv) broadening its customer base in new and
existing markets. The Company is currently developing improved pitches for the
aluminum industry, specialty coal tar pitches to be used in electrode carbon
markets and additional downstream applications for naphthalene in the super-
plasticizer and other specialty chemical markets.

COMPETITIVE STRENGTHS
 
  Strong Customer Relationships--The "Koppers" name has been associated with
quality and reliability since the 1920s. The Company's reputation has enabled
it to include among its customers numerous companies preeminent in their
respective markets, including Aluminum Company of America ("Alcoa"), CSX
Transportation, Inc. ("CSX"), LTV Steel Company, Inc. ("LTV") and UCAR Carbon
Company Inc. ("UCAR"). In order to enhance these relationships, the Company has
in place programs to ensure quality and customer satisfaction. In addition, the
Company's facilities are strategically located to service its customers'
requirements.
 
  Broad Product Line--The Company sells a wide variety of products to a diverse
customer base, including steel producers, aluminum smelters, railroads,
utilities, rubber tire producers, wood treaters, producers of polyester resins,
paints, coatings and plasticizers, the roofing industry and pavement sealer
manufacturers. The Company's broad product line and customer base allow it to
reduce its exposure to any one market segment.
 
  Long Term Sales Contracts--Historically, the Company has sought to reduce its
exposure to the cyclicality of its customers' businesses and general economic
conditions by securing commitments for a large portion of its planned
production through annual and multi-year contracts. In each of the last five
years, the Company has been able to secure over 50% of the following year's
sales through such contracts.
 
  Global Presence--The Company, along with its joint venture in Denmark,
Tarconord, serves the North American, European, Asian and Australian markets
with carbon materials and chemical products. The Company works closely with
Tarconord on marketing strategy, raw material sourcing and technology sharing.
The Company and Tarconord have completed several acquisitions and have entered
into marketing agreements enabling the Company to expand its presence into new
and emerging markets, including the United Kingdom, Middle East, South Africa,
People's Republic of China and other Pacific Rim nations.
 
  Diversified Supply Base--The Company believes that its ability to source
high-quality coal tar, wood and coal from multiple suppliers provides it with a
significant competitive advantage in meeting customer requirements in a timely
and economically advantageous manner. In addition, the Company believes its
ability to source coal tar globally is critical to obtaining the quality of
coal tar needed to satisfy its global customers' needs.
 
  Vertical Integration--The Company's ability to utilize, in its manufacturing
processes, products produced in its Carbon Materials & Chemicals and Coke
Products divisions provides the Company with significant cost savings. The
Company also believes it has a significant cost advantage over its competitors
as a result of its ability to use internally generated naphthalene as a primary
feedstock in the production of PAA. All of the Company's domestic competitors
currently use orthoxylene, which is generally a higher-cost feedstock than
naphthalene, in the production of PAA. Creosote, a major by-product of the coal
tar distillation process, is used as a raw material in the treatment of wood by
the Company's Railroad & Utility Products division.
 
  Tax Credits--The Company's coke facility located in Monessen, Pennsylvania
(the "Monessen Facility") qualifies for a tax credit based on its production of
coke as a non-conventional fuel source and the sale thereof to unrelated third
parties. The credit is available through December 31, 2002 and, based on
current production levels at the Monessen Facility, could provide up to a
maximum $10.2 million of tax credits annually, unadjusted for inflation and
assuming full production at the Monessen Facility, until the credit expires.
Use of the tax credits is limited to the availability of taxable income. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Results of Operations." The Company may monetize all or some
portion of these tax credits.
 
  The Company's principal executive offices are located at 436 Seventh Avenue,
Pittsburgh, Pennsylvania 15219-1800, and its telephone number is (412) 227-
2001.

                              RECENT DEVELOPMENTS
 
SARATOGA INVESTMENT
 
  On October 15, 1997, KAP Investments, Inc. (a wholly-owned subsidiary of
Koppers Australia) and the Management Investors (as defined herein)
(collectively, the "Offeree Stockholders") acquired from Cornerstone-Spectrum,
Inc. (an affiliate of Beazer East, Inc. and Hanson PLC) its voting and non-
voting shares of common stock of Koppers Industries, Inc. ("Common Stock"). The
Offeree Stockholders utilized $52.5 million of financing from Koppers, Saratoga
Partners III, L.P. ("Saratoga") and Saratoga Koppers Funding, Inc. ("Saratoga
Koppers"). Koppers loaned the Offeree Stockholders $17.0 million, and Saratoga
and Saratoga Koppers loaned the Offeree Stockholders $35.5 million. In exchange
for forgiveness of the loans provided by Koppers, Saratoga and Saratoga
Koppers, the Offeree Stockholders subsequently transferred 1,350,820 non-voting
shares of Common Stock to Koppers and 464,180 non-voting shares of Common Stock
and 2,117,952 voting shares of Common Stock to Saratoga and Saratoga Koppers
(the "Saratoga Investment"). On December 1, 1997, Saratoga exchanged the shares
of Common Stock it acquired in the Saratoga Investment for shares of a new
series of senior convertible preferred stock of Koppers Industries, Inc., which
entitles Saratoga to elect a majority of the Board of Directors of Koppers
Industries, Inc. (the "Board of Directors") and to exercise a majority of the
voting power over all outstanding stock of Koppers Industries, Inc. with
respect to all other matters subject to a stockholder vote. See "Management--
Stockholders' Agreement; New Stockholders' Agreement" and "Certain
Transactions."
   
RECAPITALIZATION     
   
  The Company sold the Old Notes on December 1, 1997 and established with Swiss
Bank Corporation, Stamford Branch and Mellon Bank, N.A. a total of $135.0
million of senior term loan facilities and a $140.0 million senior revolving
credit facility ($40.0 million and $20.0 million of which was reserved for use
in connection with a term loan and a revolving credit facility, respectively,
of Koppers Australia) (the "New Credit Facilities"). The proceeds from the New
Credit Facilities and the sale of the Old Notes have been and are being used to
complete the following transactions: (i) the acquisition of The Broken Hill
Proprietary Company Limited's ("Broken Hill's") 50% interest in Koppers
Australia; (ii) the repayment of all of the 8 1/2% Senior Notes of Koppers
Industries, Inc. due February 1, 2004 (the "8 1/2's") tendered pursuant to a
tender offer and consent solicitation which was commenced October 20, 1997 and
which expired as of 12:00 midnight, New York City time on November 28, 1997
(the "Tender Offer"); (iii) the repayment of the outstanding indebtedness of
approximately $88.1 million under the Company's term loan and revolving credit
facilities (the "Bank Debt Refinancing"); (iv) the redemption of 1,813,200
shares of non-voting Common Stock owned by APT Holdings Corporation, an
affiliate of Mellon Bank, N.A. for $22.9 million; (v) the redemption, at $17.00
per share, of up to 25% of the shares of Common Stock owned by the current
officers of Koppers and Clayton A. Sweeney (a member of the Board of Directors)
and the redemption of up to 100% of the shares of Common Stock owned by any
other Management Investor within sixty (60) days of the consummation of the
offering and the compliance with any applicable securities laws, at the
election of such individuals, in an aggregate amount not exceeding $15.0
million; (vi) the redemption of 436,508 non-voting shares of Common Stock from
Saratoga Koppers; and (vii) the payment of related fees and expenses. The New
Credit Facilities, the sale of the Old Notes and the above transactions are
collectively referred to herein as the "Recapitalization."

                                exception therefrom, must comply with the
                                registration and prospectus delivery
                                requirements of the Securities Act in
                                connection with any resale transaction. Failure
                                to comply with such requirements in such
                                instance may result in such holder incurring
                                liability under the Securities Act for which
                                the holder is not indemnified by the Company.
 
   
Expiration Date...............  5:00 p.m., New York City time, on February 23,
                                1998, unless the Exchange Offer is extended, in
                                which case the term "Expiration Date" means the
                                latest date and time to which the Exchange
                                Offer is extended.     
 
Accrued Interest on the New
Notes  and the Old Notes......  Each New Note will bear interest from its
                                issuance date. Holders of Old Notes that are
                                accepted for exchange will receive accrued
                                interest thereon to, but not including, the
                                issuance date of the New Notes. Such interest
                                will be paid with the first interest payment on
                                the New Notes. Interest on the Old Notes
                                accepted for exchange will cease to accrue upon
                                issuance of the New Notes.

Offer.........................  The Exchange Offer is subject to certain
                                customary conditions, which may be waived by

                                Conditions."

                                facsimile thereof, in accordance with the
                                instructions contained herein and therein, and

                                Transmittal, or such facsimile, together with
                                the Old Notes and any other required

                                defined) at the address set forth herein. By
                                executing the Letter of Transmittal, each
                                holder will represent to the Company that,
                                among other things, the New Notes acquired
                                pursuant to the Exchange Offer are being
                                obtained in the ordinary course of business of

                                whether or not such person is the holder, that
                                neither the holder nor any such other person
                                has any arrangement or understanding with any
                                person to participate in the distribution of
                                such New Notes and that neither the holder nor
                                any such other person is an "affiliate," as
                                defined under Rule 405 of the Securities Act,
                                of the Company. See "The Exchange Offer--
                                Purpose and Effect of the Exchange Offer" and
                                "--Procedures for Tendering."
 
Untendered Old Notes..........  Following the consummation of the Exchange
                                Offer, holders of Old Notes eligible to
                                participate in the Exchange Offer but who do
                                not tender their Old Notes will not have any
                                further exchange rights and such Old Notes will
                                continue to be subject to certain restrictions
                                on transfer. Accordingly, the liquidity of the
                                market for such Old Notes could be adversely
                                affected.

                                Act or pursuant to another exemption under the
                                Securities Act, (iii) outside the United States
                                to a foreign person pursuant to the
                                requirements of Rule 904 under the Securities
                                Act or (iv) pursuant to an effective

                                resales of the Old Notes held by any such
                                holders.

                                therefore, will not bear legends restricting
                                their transfer and (ii) the holders of New

                                entitled to the benefits of the Indenture. See

Maturity Date.................  December 1, 2007.
 
Subordination.................  The Notes will be general unsecured obligations
                                of the Company, subordinated in right of
                                payment to all existing and future Senior Debt
                                of the Company, including the New Credit
                                Facilities. In addition, the Notes will be
                                effectively subordinated to all secured
                                obligations to the extent of the assets
                                securing such obligations, including under the
                                New Credit Facilities. At September 30, 1997 on
                                a pro forma basis after giving effect to the
                                Saratoga Investment and the Recapitalization,
                                Koppers would have had $177.4 million of Senior
                                Debt outstanding, all of which would have been
                                secured. The Indenture permits Koppers to incur
                                additional indebtedness, including Senior Debt,
                                subject to certain limitations. See

                                subsidiaries, Koppers Australia, and
                                substantially all of the significant wholly-
                                owned subsidiaries of Koppers Australia and
                                each subsidiary that in the future guarantees
                                the New Credit Facilities (collectively, the
                                "Subsidiary Guarantors"). The Subsidiary
                                Guarantees are joint and several, general
                                unsecured obligations of the Subsidiary
                                Guarantors. The Subsidiary Guarantors
                                guaranteed all obligations of the Company under
                                the New Credit Facilities, and each Subsidiary

(1) Operating profit for 1994 reflects $2.5 million of severance charges.
    Operating profit for the nine months ended September 30, 1996 reflects $7.4
    million of plant closing charges and $2.6 million of severance charges.
    Operating profit for the year ended December 31, 1996 actual and pro forma
    and for the twelve months ended September 30, 1997 pro forma includes an
    additional $5.4 million of capacity rationalization charges. See

    to limitations under the terms of covenants contained in its debt
    instruments, to redeem stock held by Management Investors upon termination
    of their employment with Koppers.     
(5) "EBITDA" is as defined in the Indenture. See "Description of Notes." EBITDA
    is presented not as an alternative measure of operating results or cash
    flow from operations (as determined in accordance with generally accepted
    accounting principles), but rather to provide additional information
    related to the debt servicing ability of the Company. The Company's
    definition of EBITDA may not be comparable to other companies' definitions
    of EBITDA. Amortization of deferred financing fees is included in the
    Company's financial statements in depreciation and amortization and
    amounted to $0.8 million, $0.9 million, $0.7 million, $0.5 million and $0.5
    million for fiscal years 1994, 1995 and 1996 and for the nine month periods
    ended September 30, 1996 and 1997, respectively. Amortization of deferred
    financing fees for the year ended December 31, 1996 pro forma, the nine
    months ended September 30, 1997 pro forma and the twelve month period ended
    September 30, 1997 pro forma amounted to $1.5 million, $1.1 million and
    $1.5 million, respectively.
(6) "Adjusted EBITDA" is defined as EBITDA plus the cash portion of non-
    recurring charges. The non-recurring charges include the following: 1994--
    $2.5 million of severance charges; 1996--$15.5 million of restructuring
    charges and $12.6 million of litigation charges for the year ended December
    31, actual and pro forma; $10.1 million of restructuring charges and $10.1
    million of litigation charges for the nine months ended September 30; and
    1997--$1.4 million write-off of costs related to an Initial Public Offering
    (the "IPO") for the nine months ended September 30, actual and pro forma;
    $5.4 million of restructuring charges, $2.5 million of litigation charges
    and $1.4 million write-off of IPO costs for the twelve months ended
    September 30 pro forma. Adjusted EBITDA is presented not as an alternative
    measure of operating results or cash flow from operations (as determined in
    accordance with generally accepted accounting principles), but rather to
    provide additional information related to the debt servicing ability of the
    Company.

(7) The 1994 results reflect a $1.4 million reduction in depreciation expense
    for change in estimate of useful lives of certain assets effective July 1,
    1994. See Note 1 of the Notes to Consolidated Financial Statements of the
    Company.
(8) Acquisitions and related capital expenditures for 1995 include

    expenditures for fiscal year 1996 and the nine month period ended September

    of a coal tar distillation facility in Clairton, Pennsylvania. Acquisitions
    and related capital expenditures for all pro forma periods include $65
    million related to the Koppers Australia Acquisition.
(9) For purposes of calculating the ratio of earnings to fixed charges (i)
    earnings consist of income before taxes, extraordinary items and cumulative
    effects of accounting changes plus fixed charges and (ii) fixed charges
    consist of interest expense incurred excluding amortization of deferred
    financing costs, and 41% of rental payments under operating leases (an
    amount estimated by management to be the interest portion of such rentals).

SUBSTANTIAL LEVERAGE; ABILITY TO SERVICE DEBT
 
  The Company is highly leveraged and has significant debt service
requirements. At September 30, 1997, on a pro forma basis after giving effect
to the Saratoga Investment and the Recapitalization, the Company would have
had $352.4 million of long-term debt outstanding, $177.4 million of which
would have been secured. It is anticipated that under the New Credit
Facilities, the Company will have scheduled principal payments aggregating
$11.0 million, $16.0 million and $21.0 million for the years 1998, 1999 and
2000, respectively, increasing to a maximum of $45.0 million in 2003. For the
nine months ended September 30, 1997, on a pro forma basis, the Company's
earnings to fixed charges coverage ratio would have been 1.68 to 1.
 
  The degree to which the Company is leveraged will have important
consequences to holders of the Notes, including: (i) the ability of the
Company to obtain additional financing, whether for working capital, capital
expenditures, or other purposes, may be impaired; (ii) a substantial portion
of the Company's cash flow from operations will be required for debt service,
thereby reducing funds available to the Company for its operations; (iii) the
Company will be substantially more leveraged than certain of its competitors,
which might place the Company at a competitive disadvantage; (iv) the
Company's flexibility in planning for or reacting to changes in market
conditions may be limited; (v) the Company may be more vulnerable upon a
downturn in its business; and (vi) to the extent that the Company incurs any
indebtedness at variable rates, including under the New Credit Facilities, the
Company will be vulnerable to increases in interest rates.
 
  Based on current operations (assuming the Company does not incur any
material liabilities not presently known to the Company (including any such
environmental liabilities)), the Company expects that it will be able to meet
the debt service requirements on its indebtedness, meet its working capital
needs and fund its capital expenditures and other operating expenses out of
cash flow from operations and available borrowings under the New Credit
Facilities. However, there can be no assurance that the Company's business
will generate cash flow at levels sufficient to meet these requirements. If
the Company is unable to generate sufficient cash flow from operations to
service its debt obligations and to meet other cash requirements, it may be
required to sell assets, reduce capital expenditures, refinance all or a
portion of its existing debt (including the Notes) or obtain additional
financing. There can be no assurance that any such asset sales or refinancing
would be possible or that any additional financing would be available, if at
all, on terms acceptable to the Company. The Company's ability to meet its
debt service obligations will be dependent upon its future performance which,
in turn, will be subject to future economic conditions and to financial,
business and other factors, many of which are beyond the Company's control.
 
SUBORDINATION OF NOTES AND SUBSIDIARY GUARANTEES
 
  The payment of principal of and interest on, and any premium or other
amounts owing in respect of, the Notes is subordinated to the prior payment in
full of all existing and future Senior Debt of the Company, including all
amounts owing or guaranteed under the New Credit Facilities. The Subsidiary
Guarantees are similarly subordinated to Guarantor Senior Debt. Consequently,
in the event of a bankruptcy, liquidation, dissolution, reorganization or
similar proceeding with respect to the Company or a Subsidiary Guarantor,
assets of the Company or such Subsidiary Guarantor will be available to pay
obligations on the Notes or Subsidiary Guarantees only after all Senior Debt
of the Company or Guarantor Senior Debt, as applicable, has been paid in full,
and there can be no assurance that there will be sufficient assets to pay
amounts due on any or all of the Notes. In addition, neither the Company nor
any Subsidiary Guarantor may pay principal, premium, interest or other amounts
on account of the Notes or any Subsidiary Guarantee in the event of a payment
default in respect
 
                                      16
<PAGE>
 
of Designated Senior Debt (as defined herein) unless such amount has been paid
in full or the default has been cured or waived. In addition, in respect of
certain Designated Senior Debt and unless certain other conditions are
satisfied, neither the Company nor any Subsidiary Guarantor may make any
payment on account of the Notes for a designated period of time. See
"Description of Notes--Subordination." At September 30, 1997, after giving pro
forma effect to the Saratoga Investment and the Recapitalization, the Company
would have had $177.4 million of Senior Debt and/or Guarantor Senior Debt
outstanding. See "Description of Notes--Ranking."
 
FRAUDULENT CONVEYANCE STATUTES
 
  The incurrence of indebtedness (such as the Notes), and the use of the
proceeds thereof in connection with the Koppers Australia Acquisition, the APT
Holdings Corporation redemption, the Saratoga Koppers redemption and the
Management Redemption Offer (as defined herein), is subject to review under
relevant federal and state fraudulent conveyance and similar statutes in a
bankruptcy or reorganization case or a lawsuit by or on behalf of creditors of
the Company. Under these statutes, if a court were to find that obligations
(such as the Notes) were incurred with the intent of hindering, delaying or
defrauding present or future creditors, that the Company received less than a
reasonable equivalent value of fair consideration for those obligations or
that the Company contemplated insolvency with a design to prefer one or more
creditors to the exclusion, in whole or in part, of other creditors and, at
the time of incurrence of the obligations, the obligor (i) was insolvent or
rendered insolvent by reason thereof, (ii) was engaged or was about to engage
in a business or transaction for which its remaining unencumbered assets
constituted unreasonable small capital or (iii) intended to or believed that
it would incur debts beyond its ability to pay such debts as they matured or
became due, such court could void the Company's obligations under the Notes,
subordinate the Notes to other indebtedness of the Company or take other
action detrimental to the holders of the Notes. Some courts have held that an
obligor's purchase of its own capital stock does not constitute reasonably
equivalent value or fair consideration for indebtedness incurred to finance
that purchase.
 
  To the extent that the Subsidiary Guarantee of any Subsidiary Guarantor is
avoided as a fraudulent conveyance or found unenforceable for any other
reason, holders of the Notes would cease to have any claim in respect of such
Subsidiary Guarantor. However, under U.S. law under certain circumstances,
claims may be subordinated and, in such event, the claims of the holders of
the Notes against such Subsidiary Guarantor would be subject to the prior
payment of all liabilities and preferred stock claims, if any, of such
Subsidiary Guarantor. There can be no assurance that, after providing for all
prior claims and preferred stock interests, if any, there would be sufficient
assets to satisfy the claims of the holders of the Notes relating to any
voided portion of the Subsidiary Guarantee of such Subsidiary Guarantor.
 
  In addition, various statutes have been enacted and various principles have
been developed in Australia under common law and equitable doctrines for the
benefit of creditors. Under Australian law, a guarantee given by a company may
be set aside on a number of grounds. For example, a guarantee may be
unenforceable against a guarantor if (i) the rules permitting a liquidator to
successfully claim and void the guarantee are applicable (as described below)
or (ii) the guarantor itself did not receive a sufficient commercial benefit
in order to justify such guarantor providing the guarantee. Issues as to
unenforceability of a guarantee by reason of insufficient corporate benefit
may arise where a company in a corporate group, such as Koppers Australia,
provides a guarantee in relation to the obligations of another member of the
corporate group. The question of what constitutes a sufficient benefit is a
fact-based qualitative inquiry, to be made for each guarantor individually as
a separate legal entity, which weighs several considerations, including
circumstances pertaining to (i) the nature of the relationship between the
group companies, (ii) the nature and present value of the benefit and the
burden of the obligations that will flow to each party to the transaction and
(iii) the knowledge of the directors of each guarantor as to the decisions
made by such guarantor. Each of the Subsidiary Guarantors will represent and
warrant in the Indenture, for the benefit of the holders of the Notes, that
its obligations have been undertaken in good faith and for the purpose of or
in connection with the conduct of its business and for its commercial benefit,
which is commensurate with the obligations undertaken by it. However, such
representations and warranties may not be determinative of the matter if it
were to be considered by a court. Under Australian law, it is possible that
 
                                      17
<PAGE>
 
in a proceeding to enforce the Subsidiary Guarantees, each Subsidiary
Guarantee will be analyzed differently and produce different results.
 
  Under Australian law, if an order to wind up were to be made against Koppers
Australia and a liquidator appointed for Koppers Australia, such liquidator
would have the power to investigate the validity of past transactions and may
seek various court orders, including orders to avoid certain transactions
entered into prior to the winding-up of Koppers Australia and for the
repayment of money. Under Australian Corporations Law, a transaction may be
voided at the claim of a liquidator if it was entered into during various time
periods prior to the filing of an application for a winding-up of a company,
ranging from six months to ten years, depending upon the character of the
transaction. There can be no assurance that one or more of the Subsidiary
Guarantees will not be avoided and that holders of the Notes will not be left
with a claim solely against Koppers Industries, Inc.
 
  The measure of insolvency for purposes of a fraudulent conveyance claim will
vary depending upon the law of the jurisdiction being applied. Generally,
however, a company will be considered insolvent at a particular time if the
sum of its debts at that time is greater than the fair value of its assets or
if the fair salable value of its assets at that time is less than the amount
that would be required to pay its probable liability on its existing debts as
they become absolute and mature.
 
  On the basis of its historical financial information, its recent operating
history as discussed in "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and other factors, the Company believes
that, after giving effect to the Saratoga Investment and the Recapitalization,
the Company will be (i) neither insolvent nor rendered insolvent by the
incurrence of indebtedness in connection with the Saratoga Investment and the
Recapitalization, (ii) in possession of sufficient capital to run its business
effectively and (iii) incurring debts within its ability to pay as the same
mature or become due. There can be no assurance, however, as to whether a
court would concur with such beliefs.
 
RESTRICTIONS IMPOSED BY CERTAIN COVENANTS
 
  The New Credit Facilities and the Indenture contain a number of significant
covenants that, among other things, restrict the ability of the Company to
dispose of assets, incur additional indebtedness, incur liens on property or
assets, repay other indebtedness, pay dividends, enter into certain
investments or transactions, repurchase or redeem capital stock, engage in
mergers or consolidations, or engage in certain transactions with subsidiaries
and affiliates and otherwise restrict corporate activities. There can be no
assurance that such restrictions will not adversely affect the Company's
ability to finance its future operations or capital needs or engage in other
business activities that may be in the interest of the Company. In addition,
the New Credit Facilities also require the Company to maintain compliance with
certain financial ratios. The ability of the Company to comply with such
ratios may be affected by events beyond the Company's control. A breach of any
of these covenants or the inability of the Company to comply with the required
financial ratios could result in a default under the New Credit Facilities. If
any such default occurs, the lenders under the New Credit Facilities could
elect to declare all borrowings outstanding under the New Credit Facilities,
together with accrued interest and other fees, to be due and payable. If the
Company were unable to repay any such borrowings when due, the lenders under
the New Credit Facilities could proceed against their collateral. If the
indebtedness under the New Credit Facilities or the Notes were to be
accelerated, there can be no assurance that the assets of the Company would be
sufficient to repay such indebtedness in full. Any such default may have a
material adverse effect on the Company's financial condition and results of
operations. See "Description of New Credit Facilities" and "Description of
Notes."
 
CONTROL OF THE COMPANY
   
  Under the Stockholders' Agreement, Saratoga has the right to elect a
majority of the Board of Directors. Consequently, Saratoga will have the
ability to control the election of the Board of Directors and the outcome of
other issues submitted to the stockholders for approval. See "Principal
Stockholders."     
 
                                      18

CYCLICALITY OF MARKETS
 
  The Company's products are sold primarily in mature markets which
historically have been cyclical. The principal consumers of the Company's
pitch, the most significant product of its Carbon Materials & Chemicals
division, are United States primary aluminum smelters. Although the aluminum
industry has experienced growth on a long-term basis, it generally is cyclical
in nature and experiences fluctuations in production levels. There may be
cyclical periods of weak demand which could result in decreased United States'
primary aluminum production. Sales of the Company's products have historically
been affected adversely by weakness in the global demand for aluminum.
 
  Principal products utilizing the Company's PAA include flexible vinyl used
mainly in the automobile industry. Therefore, fluctuations in domestic and
international automobile production affect the demand for PAA.
 
  The principal customers for the Company's coke are United States integrated
steel producers, whose consumption of coke has been cyclical in the past and
may be so in the future. The prices at which the Company will be able to sell
its coke in the future will be greatly affected by the demand for coke from
the iron and steel industries and the supply of coke from the United States
integrated steel producers' own coke production and from foreign sources.
 
DEPENDENCE ON MAJOR CUSTOMERS
 
  For the year ended December 31, 1996, the Company's top five customers
accounted for approximately 25% of the Company's net sales. During this
period, the Company's two largest customers, CSX and LTV, accounted for
approximately 5% and 9% of the Company's total net sales, respectively. The
permanent loss of, or a significant decrease in the level of purchases by, one
or more of the Company's major customers could have a material adverse effect
on the Company's results of operations.
 
PRICE AND AVAILABILITY OF RAW MATERIALS
 
  An inability of the Company to source quality raw materials in a timely
fashion and pass through price increases to its customers could have a
material adverse impact on the Company's financial condition and results of
operations. The primary raw material used by the Carbon Materials & Chemicals
division is coal tar, a by-product of coke production. Following the Clean Air
Act Amendments of 1990 (the "Clean Air Act Amendments") and other
environmental regulations, there have been significant reductions in United
States coking capacity. Due to potential additional reductions in United
States and Australian coking capacity, future coal tar availability is a
concern for the Company. A shortage in the supply of domestic coal tar could
require the Company to increase imports of coal tar and carbon pitch, as well
as the use of petroleum substitutes to meet future carbon pitch demand; such
actions could have a material adverse effect on the Company's financial
condition and results of operations.
 
  The availability and cost of softwood and hardwood lumber are critical
elements in the Company's 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 the
Company accordingly has 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. There
can be no assurance that the Company will be able to source wood raw materials
at economical prices in the future.
 
  In the Coke Products division, 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 supply, could have a
material adverse effect on the Company.
 
 
                                      19
<PAGE>
 
COMPETITION
 
  The markets that the Company serves are highly competitive. Selling price is
the most significant competitive factor in the markets for the Company's
principal products. In addition, some of the purchasers of the Company's 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 United States suppliers. There can be no assurances that competitive
pressures on the price of the Company's products will not materially and
adversely affect its business, results of operations, cash flow and financial
condition. Certain competitors of the Company have greater financial resources
and larger capitalization than the Company and, as a result, may be better
able to withstand volatile market conditions and price competition.
 
ENVIRONMENTAL MATTERS
 
  Like companies involved in similar environmentally sensitive businesses, the
Company's operations and properties are subject to extensive federal, state,
local and foreign environmental laws and regulations, including those
concerning, 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 emissions of substances into the
air or otherwise relating to environmental protection and various health and
safety matters (collectively, "Environmental Laws"). The Clean Air Act and
Clean Water Act, each as amended, impose stringent standards on air emissions
and water discharges, respectively. Under the Resource Conservation and
Recovery Act, as amended ("RCRA"), a facility that treats, stores or disposes
of hazardous waste on-site may be liable for corrective action costs, and a
facility that holds a RCRA permit may have to incur costs relating to the
closure of certain "hazardous" or "solid" waste management units. Under the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980,
as amended ("CERCLA") and similar state laws, an owner or operator of property
at which releases of hazardous substances have occurred may be liable for
investigation and remediation of any resulting contamination and related
natural resource damages. In addition, under CERCLA, the generator of
hazardous substances may be strictly, and jointly and severally liable for any
required investigation or remediation at third-party disposal sites and
related natural resource damages. The Environmental Laws are subject to
frequent amendment. The sanction for failure to comply with such Environmental
Laws can include significant civil penalties, criminal penalties, injunctive
relief and denial or loss of, or imposition of significant restrictions on,
environmental permits. In addition, the Company could be subject to suit by
third parties in connection with violations of or liability under
Environmental Laws.
 
  In March 1996, Jefferson County, Alabama ("Jefferson County") issued a
notice of violation in connection with various alleged violations of air
pollution control regulations regarding emissions from coke oven batteries at
Koppers' coke facility located in Woodward, Alabama ("the Woodward Coke
Facility"). In February 1997, the United States Environmental Protection
Agency ("US-EPA") issued a notice of violation covering the same issues.
Thereafter, Koppers discovered that certain benzene abatement equipment at
this Facility had not been operational for several months. Koppers and
Jefferson County have negotiated a settlement agreement which includes both
the original Jefferson County notice of violation and the self-reported
benzene abatement violation, and requires Koppers to pay a civil penalty in
the amount of $450,000, which sum has been paid. There can be no assurance
that the settlement with Jefferson County will deter the US-EPA from pursuing
its notice of violation. Following a preliminary investigation of the Woodward
Coke Facility, Koppers also discovered that certain environmental reports and
records required under the Clean Water Act contained incomplete and inaccurate
information and that certain environmental reports and certifications were not
filed when required. Corrected reports have been submitted to Jefferson
County, the State of Alabama and the US-EPA. In June 1997, during a routine
environmental compliance audit of the Logansport Wood Treating Facility, it
was discovered that certain records and reports required under the Clean Water
Act contained incomplete and inaccurate information. Corrected reports have
been submitted to the local municipality, the State of Louisiana and the US-
EPA. Although no notice of violation has been issued in conjunction with this
issue, it is likely that such a notice will be issued and substantial
penalties sought by the regulatory authorities. On April 25, 1997, Koppers was
served with notices of violation by the Pennsylvania Department of
Environmental Protection ("Pa-DEP")
 
                                      20
<PAGE>
 
which alleged that Koppers was in violation of a Pa-DEP plan approval for the
Monessen Facility regarding nitrogen oxide emissions and failed to conduct
timely emission testing on Monessen Facility boilers. Koppers could be subject
to significant liability in connection with each of these matters, including
injunctive relief, substantial civil and criminal penalties and the risk of
third-party lawsuits. Resolution of these and other pending compliance matters
could have a negative effect on the business, financial condition, cash flow
and results of operations of the Company.
 
  For each of the last three fiscal years, the Company's average capital
expenditures and operating expenses for environmental matters, including
depreciation, amounted to approximately $7.0 million and $16.0 million,
respectively. The Company believes that environmental operating costs will not
change materially from those incurred during the past three years. The Company
currently estimates that capital expenditures in connection with matters
relating to environmental control will be approximately $3.8 million and $6.9
million for 1997 and 1998, respectively. Because Environmental Laws have
historically become increasingly more stringent, costs and expenses relating
to environmental control and compliance may increase in the future. Also,
Koppers may have to incur additional capital expenditures and compliance costs
(which it is unable to estimate at this time) in connection with the
resolution of the aforementioned notices of violations. As such, there can be
no assurance that costs of compliance with existing and future Environmental
Laws will not exceed current estimates and will not have a material adverse
effect on the Company's business, financial condition, cash flow and results
of operations.
 
  Under the terms of the asset purchase agreement between Koppers Industries,
Inc. and Koppers Company, Inc. (now known as Beazer East, Inc.) at the
formation of Koppers in 1988 (the "Asset Purchase Agreement"), Beazer East,
Inc. ("Beazer East") assumed the liability for and indemnified Koppers against
(among other things) cleanup 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's performance
of the Indemnity is unconditionally guaranteed by Beazer Limited (the "Beazer
Guarantee"). Contamination identified at sites owned and/or operated by
Koppers is being investigated and remediated under CERCLA, RCRA or state
cleanup programs. Currently, at the sites acquired from Beazer East (which
include all of the CERCLA sites and all but one of the RCRA sites),
substantially all investigation and remediation activities are being conducted
and paid for by Beazer East pursuant to the terms of the Indemnity, however,
there can be no assurance that Beazer East and Beazer Limited will continue to
meet their obligations. In the event they do not, Koppers may be required to
pay such costs which are believed to have averaged approximately $13 million
per year for the last three years. In addition, the government and other third
parties have the right under applicable Environmental Laws to seek relief
directly from Koppers for any and all such costs and liabilities. The
requirements to pay such costs and assume such liabilities without
reimbursement would have a material adverse affect on the business, financial
condition, cash flow and results of operations of the Company. Furthermore, if
Koppers were required to record a contingent liability in respect of
environmental matters covered by the Indemnity on its balance sheets, the
result could be that the Company would have significant negative net worth.
 
  The Indemnity does not afford Koppers indemnification against environmental
costs and liabilities relating to activities or conditions occurring or
arising after the closing of the acquisition of assets from Beazer East under
the Asset Purchase Agreement (the "Asset Closing"), nor is the Indemnity
applicable to liabilities arising in connection with post-closing
acquisitions. At the Clairton facility, the Somerville facility and the
Monessen Facility (each of which Koppers acquired subsequent to the
acquisition of the Beazer East sites), investigations and remediations are
being performed. All applicable indemnification obligations are being honored
at the Clairton and Somerville facilities, and Koppers believes that the
sellers (or their predecessors) at both of these facilities will continue to
conduct and finance most activities directly. Although the Company is not
aware of any reason why such environmental indemnification obligations will
not be performed, if Koppers were required to pay costs associated with these
two sites, it could have a material adverse effect on the Company's business,
financial condition, cash flow and results of operations. At the Monessen
Facility, Koppers has entered into a consent order and agreement (the
"Monessen Consent Order") with Pa-DEP pursuant to which Koppers' liabilities
for environmental cleanup have been capped at $550,000 for matters identified
pursuant to the
 
                                      21
<PAGE>
 
Monessen Consent Order. Although an environmental indemnification was provided
to Koppers by the seller of that facility, the Company does not expect that
such obligations will be honored. If contamination at the Monessen Facility
should be discovered which is not identified pursuant to the Monessen Consent
Order or if the US-EPA should require cleanup above the $550,000 "cap"
contained therein, costs associated with such events could have a material
adverse effect on the Company's business, financial position, cash flow and
results of operations. See "Business--Environmental Matters."
 
ROOFING CLAIMS
 
  From time to time, the Company is placed on notice of claims and/or suits
arising out of the commercial roofing businesses of the Company. Certain of
such claims are tendered to Beazer East pursuant to the Indemnity. Other such
claims are defended and, where appropriate, settled by the Company. Koppers
maintains a built-up roofing reserve for such claims. As of September 30,
1997, the built-up roofing reserve balance was approximately $4.6 million. The
Company also has comprehensive general liability insurance which includes a
self-insured retention, and also has excess coverage. When appropriate,
insurance carriers are notified of roofing claims. Typically, such claims fall
within the Company's self-insured retention. To the extent that any roofing
claim may exceed the Company's self-insured retention, coverage will depend
upon the specifics of the claim. Depending upon the amount of future claims,
such claims could have a material adverse effect on the Company's business,
financial condition, cash flow and results of operations.
 
LABOR RELATIONS
 
  As of August 31, 1997, approximately 1,400 of the Company's 2,244 employees
were represented by seventeen different labor unions and covered under 29
separate labor contracts. Labor negotiations are conducted on a plant-by-plant
basis and approximately one-fourth of the outstanding contracts are
renegotiated in any one year. Although the Company believes that it generally
enjoys satisfactory relations with its unions, there can be no assurance that
new agreements will be reached without union action or on terms satisfactory
to the Company. A material work stoppage could adversely affect the Company's
results of operations.
 
  In the last five years, the Company has had three work stoppages due to
strikes at its Follansbee (West Virginia), Somerville (Texas) and Galesburg
(Illinois) facilities. The Follansbee strike occurred in November 1993 and the
Somerville and Galesburg strikes occurred in March 1996. In each instance, the
Company was able to continue operation of the respective facilities at
approximately 85% of capacity and to reach agreement with each of the unions
on terms satisfactory to the Company. There can be no assurance that the
Company will be able to continue operating facilities in the event of further
work stoppages or union disputes in the future.
 
SEASONALITY; EFFECTS OF WEATHER
 
  Koppers' quarterly operating results fluctuate due to a variety of factors
that are outside Koppers' control, including inclement weather conditions,
which in the past have affected negatively Koppers' operating results.
Operations at several of Koppers' facilities have been halted for short
periods of time during the winter months. Moreover, demand for many of
Koppers' products declines during periods of inclement weather. As a result of
the foregoing, Koppers' anticipates that it may experience material
fluctuations in quarterly results of operations. Over the last five years, the
first, second, third and fourth quarters have averaged 19%, 28%, 29% and 24%,
respectively, of annual Adjusted EBITDA.
 
FOREIGN OPERATIONS
 
  The Company, both directly and through Tarconord, has operations in seven
foreign countries and sells its products in 13 foreign countries. In both
fiscal 1996 and for the nine months ended September 30, 1997, net sales from
the Company's products sold abroad accounted for approximately 20% of its
total net sales. Risks inherent in foreign operations include changes in
social, political and economic conditions. Changes in currency exchange rates
may affect the relative prices at which the Company and foreign competitors
purchase and sell their products in the same market. The Company does not
routinely hedge its exposure to foreign currency
 
                                      22
<PAGE>
 
exchange rate changes. The Company is also exposed to risks associated with
changes in the laws and policies that govern foreign investments in countries
where it has operations as well as, to a lesser extent, changes in United
States laws and regulations relating to foreign trade and investment. While
such changes in laws, regulations and conditions to date have not had a
material adverse effect on the Company's business or financial condition,
there can be no assurance as to the future effect of any such changes.
 
CHANGE OF CONTROL
 
  Upon a Change of Control, the holders of the Notes have the right to require
the Company to offer to purchase all of the outstanding Notes at 101% of the
principal amount thereof, plus accrued and unpaid interest to the date of
purchase. There can be no assurance that the Company will have sufficient
funds available or will be permitted by its other debt agreements to purchase
the Notes upon the occurrence of a Change of Control. In addition, a Change of
Control may require the Company to offer to purchase other outstanding
indebtedness and may cause a default under the New Credit Facilities. The
inability to purchase all of the tendered Notes would constitute an Event of
Default (as defined herein) under the Indenture. See "Description of Notes--
Change of Control."
 
LACK OF ESTABLISHED MARKET FOR THE NOTES
 
  Prior to the Exchange Offer, there has not been any public market for the
Old Notes. The Old Notes have not been registered under the Securities Act and
will be subject to restrictions on transferability to the extent that they are
not exchanged for the New Notes by holders who are entitled to participate in
the Exchange Offer. The holders of Old Notes (other than any such holder that
is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act) who are not eligible to participate in the Exchange Offer are
entitled to certain registration rights, and the Company is required to file a
Shelf Registration Statement with respect to such Old Notes. The New Notes
will constitute a new issue of securities with no established trading market.
The Company does not intend to list the New Notes on any securities exchange
or to seek their admission to trading in any automated quotation system. The
Initial Purchaser has advised the Company that they currently intend to make a
market in the New Notes, but they are not obligated to do so and may
discontinue such market-making at any time without notice. In addition, such
market-making activity will be subject to the limits imposed by the Securities
Act and the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
and may be limited during the Exchange Offer and the pendency of any Shelf
Registration Statement. Accordingly, no assurance can be given that an active
public or other market will develop for the New Notes or as to the liquidity
of the trading market for the New Notes. If a trading market does not develop
or is not maintained, holders of the New Notes may experience difficulty in
reselling the New Notes or may be unable to sell them at all. If a market for
the New Notes develops, any such market may be discontinued at any time.
 
  If a public trading market develops for the New Notes, future trading prices
of the New Notes will depend on many factors, including, among other things,
prevailing interest rates, the Company's operating results and the market for
similar securities. Depending on prevailing interest rates, the market for
similar securities and other factors, including the financial condition of the
Company, the New Notes may trade at a discount from their principal amount.
 
FAILURE TO FOLLOW EXCHANGE OFFER PROCEDURES; CONSEQUENCES OF FAILURE TO
EXCHANGE
 
  Issuance of the New Notes in exchange for the Old Notes pursuant to the
Exchange Offer will be made only after a timely receipt by the Company of such
Old Notes, a properly completed and duly executed Letter of Transmittal and
all other required documents. Therefore, holders of the Old Notes desiring to
tender such Old Notes in exchange for New Notes should allow sufficient time
to ensure timely delivery. The Company is under no duty to give notification
of defects or irregularities with respect to the tenders of Old Notes for
exchange. Old Notes that are not tendered or are tendered but not accepted
will, following the consummation of the Exchange Offer, continue to be subject
to the existing restrictions upon transfer thereof and, upon consummation
 
                                      23

of the Exchange Offer, certain registration rights under the Registration
Rights Agreement will terminate. In addition, any holder of Old Notes who
tenders in the Exchange Offer for the purpose of participating in a
distribution of the New Notes may be deemed to have received restricted
securities and, if so, will be required to comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale transactions. Each holder of the Old Notes (other than certain
specified holders) who wishes to exchange the Old Notes for New Notes in the
Exchange Offer will be required to represent in the Letter of Transmittal that
(i) it is not an affiliate of the Company, (ii) the New Notes to be received
by it are being acquired in the ordinary course of its business and (iii) at
the time of commencement of the Exchange Offer, it has no arrangement with any
person to participate in the distribution (within the meaning of the
Securities Act) of the New Notes. Each Participating Broker-Dealer that
receives New Notes for its own account in exchange for Old Notes, where such
Old Notes were acquired by such Participating Broker-Dealer as a result of
market-making activities or other trading activities, must acknowledge that it
will deliver a prospectus in connection with any resale of such New Notes. See
"Plan of Distribution." To the extent that Old Notes are tendered and accepted
in the Exchange Offer, the trading market for untendered and tendered but
unaccepted Old Notes could be adversely affected. See "The Exchange Offer."
 
                                COMPANY HISTORY
 
  The original predecessor to Koppers Company, Inc. was formed in 1912 by a
metallurgist named Heinrich Koppers to design and build coke ovens (Koppers
Company, Inc. and its predecessors are collectively referred to as "Old
Koppers"). Old Koppers gradually expanded into related industries including
coal, gas, chemicals, wood treating, building products, metals and road
materials. Koppers Australia was formed in 1967 as a joint venture between Old
Koppers and Broken Hill. In June 1988, BNS Acquisitions, Inc., a wholly-owned
indirect subsidiary of Beazer PLC (now known as Beazer Limited) acquired Old
Koppers with the intent of retaining the road materials business and selling
the remaining businesses. Koppers was formed in October 1988 by management,
Beazer, Inc. and Koppers Australia to facilitate the acquisition of certain
assets of Old Koppers, including an equity interest in Koppers Australia, for
a purchase price of approximately $227 million. In 1995, the Company acquired
the Somerville, Texas crosstie treating facility ($9.8 million) and the
Monessen Facility ($25.2 million including $20.2 million of refurbishment
costs). In 1996, the Company acquired the Clairton, Pennsylvania tar
distillation facility for approximately $40.0 million cash and the assumption
of certain liabilities.
 
                                 TRANSACTIONS
   
  On October 15, 1997, the Offeree Stockholders acquired from Cornerstone-
Spectrum, Inc. its voting and non-voting shares of Common Stock in exchange
for $52.5 million of financing obtained from Koppers, Saratoga and Saratoga
Koppers. Koppers loaned the Offeree Stockholders $17.0 million, and Saratoga
and Saratoga Koppers loaned the Offeree Stockholders $35.5 million. In
exchange for forgiveness of the loan provided by Koppers, Saratoga and
Saratoga Koppers, the Offeree Stockholders subsequently transferred 1,350,820
non-voting shares of Common Stock to Koppers and 464,180 non-voting shares of
Common Stock and 2,117,952 voting shares of Common Stock to Saratoga and
Saratoga Koppers in the Saratoga Investment. On December 1, 1997, Saratoga
exchanged the shares of Common Stock it acquired in the Saratoga Investment
for shares of a new series of convertible preferred stock of Koppers
Industries, Inc. which entitles Saratoga to elect a majority of the Board of
Directors and to exercise a majority of the voting power over all outstanding
stock of Koppers Industries, Inc. with respect to all other matters subject to
a stockholder vote. See "Management--Stockholders' Agreement" and "Certain
Relationships and Related Transactions."     
 
  Pursuant to a separate Offer to Purchase and Consent Solicitation dated
October 20, 1997, Koppers offered to repurchase all of its outstanding 8 1/2's
in the Tender Offer at a price per $1,000 principal amount of the 8 1/2's
equal to (i) the present value on the payment date of $1,042.50 (the amount
payable on February 1, 1999, which is the first date on which the 8 1/2's are
redeemable) determined on the basis of a yield to such date (the "Tender
 
                                      24
<PAGE>
 
Offer Yield") equal to the sum of (x) the yield on the 5 7/8% U.S. Treasury
Note due January 31, 1999 (CUSIP: 9128272F8) (the "Reference Treasury
Security") as of 2:00 p.m., New York City time, on the second business day
immediately preceding the scheduled expiration date of the Tender Offer (the
"Price Determination Date"), plus (y) 50 basis points, minus (ii) $10.00
(collectively, the "Tender Offer Consideration"). Each tendering holder
received accrued and unpaid interest up to, but not including, the payment
date. The yield on the Reference Treasury Security as of 5:00 p.m., New York
City time, on November 13, 1997 was 5.70%. Accordingly, if such yield was
determined to be the yield on the Reference Treasury Security on the Price
Determination Date and December 1, 1997 was the payment date, the Tender Offer
Yield, the Tender Offer Consideration and the total consideration (i.e., the
Tender Offer Consideration plus the consent payment described below) per
$1,000 principal amount of the 8 1/2's would be 6.20%, $1,055.60 and
$1,065.60, respectively.
 
  In connection with the Tender Offer, Koppers obtained consents from the
tendering holders of the 8 1/2's to certain proposed amendments to the
Indenture relating to the 8 1/2's, which eliminated substantially all of the
restrictive covenants and certain events of default contained in such
Indenture. Holders of the 8 1/2's who timely consented to such amendments also
received a consent payment equal to $10.00 per $1,000 principal amount.
   
  The Tender Offer expired at 12:00 midnight, New York City time on November
28, 1997. The Company purchased $98,906,000 of the 8 1/2's in the Tender
Offer, and may repurchase 8 1/2's in the future in open market transactions,
privately negotiated purchases or otherwise, and a portion of the term loan
under the New Credit Facilities will remain initially undrawn but will be
available for such purpose. There can be no assurance, however, that the
Company will make any such repurchases at any time in the future.     
   
  Koppers has acquired Broken Hill's 50% interest in Koppers Australia (the
"Koppers Australia Acquisition"). Koppers owned the other 50% interest in
Koppers Australia, which operates businesses similar to Koppers and is the
largest Australian manufacturer and exporter of coal-tar derived products such
as carbon pitch for aluminum smelting; carbon black for tire production; and
naphthalene for use in the manufacture of plasticizers, resins and dye-making.
Koppers Australia, with operating revenue of $134.0 million in the fiscal year
ending June 30, 1997 (based on average month-end exchange rates), is also the
largest Australian producer of wood preservatives and treated timber. The
purchase price for the Koppers Australia acquisition was approximately $65.0
million.     
 
  The Company will utilize up to $15.0 million of the net proceeds available
under the New Credit Facilities or from the Offering to redeem shares of
Common Stock held by eligible Management Investors at a price of $17.00 per
share (the "Management Redemption Offer"). The Management Redemption Offer
will be open for a period of 60 days following consummation of the Offering
and the compliance with any applicable securities laws. In addition, the
Company's eight officers and Clayton A. Sweeney (a member of the Board of
Directors) will not be entitled to redeem more than 25% of the shares of
Common Stock held by them individually. Simultaneously with the Management
Redemption Offer, shares of Common Stock will be available for purchase by
Management Investors and certain employees of the Company at a price of $14.00
per share, but Management Investors redeeming shares pursuant to the
Management Redemption Offer will be prohibited from simultaneously purchasing
shares of Common Stock, whether in connection with the Management Redemption
Offer, upon the exercise of options, or otherwise.
 
  As part of the Recapitalization, the Company repaid indebtedness of
approximately $88.1 million under the Company's then current term loan and
revolving credit facilities. In addition, Koppers has entered into an
agreement with APT Holdings Corporation, an affiliate of Mellon Bank, N.A., to
redeem 1,813,200 shares of the non-voting Common Stock for $22.9 million, one-
half of which was redeemed on December 1, 1997 and the remaining shares to be
redeemed in January of 1998.
 
  Also as part of the Recapitalization, the Company redeemed 436,508 non-
voting shares of Common Stock from Saratoga Koppers and paid fees and expenses
related to the Saratoga Investment.

                                USE OF PROCEEDS
 
  The Company will not receive any proceeds from the Exchange Offer. The net
proceeds from the sale of the Old Notes, combined with net proceeds from the
New Credit Facilities, have been and are being applied to complete the
following transactions: (i) acquisition of Broken Hill's 50% interest in
Koppers Australia, which occurred on December 1, 1997; (ii) the repayment of
all of the 8 1/2's tendered pursuant to the Offer to Purchase and Consent
Solicitation dated October 20, 1997; (iii) the repayment of the outstanding
indebtedness under the Company's then current term loan and revolving credit
facilities; (iv) the redemption of 1,813,200 shares of non-voting Common Stock
owned by APT Holdings Corporation, an affiliate of Mellon Bank, N.A.; (v) the
redemption, at $17.00 per share, of up to 25% of the shares of Common Stock
owned by the current officers of Koppers and Clayton A. Sweeney and the
redemption of up to 100% of the shares of Common Stock owned by any other
Management Investor within sixty (60) days of the consummation of the Offering
and the compliance with any applicable securities laws, at the election of
such individuals, in an aggregate amount not exceeding $15.0 million; (vi) the
redemption of 436,508 non-voting shares of Common Stock from Saratoga Koppers;
and (vii) the payment of related fees and expenses. See "Transactions".

(1) Operating profit for 1994 reflects $2.5 million of severance charges.
    Operating profit for the nine months ended September 30, 1996 reflects
    $7.4 million of plant closing charges and $2.6 million of severance
    charges. Operating profit for the year ended December 31, 1996 includes an
    additional $5.4 million of capacity rationalization charges. See
    "Management's Discussion and Analysis of Financial Condition and Results
    of Operations."
 
(2) Other expense for the year ended December 31, 1996 includes a $10.1
    million charge related to the OCF Settlement and a $2.5 million legal
    settlement to CSX. Other expense for the nine months ended September 30,
    1996 does not include the CSX settlement. Other income includes $4.7
    million, $4.6 million, $5.3 million, $9.2 million, $9.6 million, $6.4
    million and $4.7 million of equity earnings in affiliates for the years
    ended December 31, 1992, 1993, 1994, 1995 and 1996, and for the nine
    months ended September 30, 1996 and 1997, respectively.

(3) Net income for 1993 includes effects of SFAS No. 106, "Employers'
    Accounting for Postretirement Benefits Other Than Pensions" of ($5.2)
    million net of tax, and SFAS No. 109, "Accounting for Income Taxes" of
    ($0.5) million net of tax. See Notes 7 and 8 of the Notes to Consolidated
    Financial Statements of Koppers. Net income for 1994 includes
    extraordinary loss on early extinguishment of debt of $1.8 million.
 
(4) On February 10, 1994 Koppers issued the 8 1/2's.
   
(5) The Stockholders' Agreement requires Koppers, subject to limitations under
    the terms of covenants contained in its debt instruments, to redeem stock
    held by Management Investors upon termination of their employment with
    Koppers.     
 
(6) EBITDA is as defined in the Indenture. See "Description of Notes." EBITDA
    is presented not as an alternative measure of operating results or cash
    flow from operations (as determined in accordance with generally accepted
    accounting principles), but rather to provide additional information
    related to the debt servicing ability of the Company. The Company's
    definition of EBITDA may not be comparable to other companies' definitions
    of EBITDA. Amortization of deferred financing fees is included in Koppers'
    financial statements in depreciation and amortization and amounts to $1.5
    million, $1.1 million, $0.8 million, $0.9 million, $0.7 million, $0.5
    million and $0.5 million for fiscal years 1992, 1993, 1994, 1995 and 1996
    and for the nine months ended September 30, 1996 and 1997, respectively.
 
(7) Adjusted EBITDA is defined as EBITDA plus the cash portion of non-
    recurring charges. The non-recurring charges include the following: 1994--
    $2.5 million of severance charges; 1996--$15.5 million of restructuring
    charges and $12.6 million of litigation charges for the year ended
    December 31; $10.1 million of restructuring charges and $10.1 million of
    litigation charges for the nine months ended September 30; and 1997--$1.4
    million write-off of costs related to the IPO for the nine months ended
    September 30. Adjusted EBITDA is presented not as an alternative measure
    of operating results or cash flow from operations (as determined in
    accordance with generally accepted accounting principles), but rather to
    provide additional information related to the debt servicing ability of
    the Company.
 
(8) The 1994 results reflect a $1.4 million reduction in depreciation expense
    for change in estimate of useful lives of certain assets effective July 1,
    1994. See Note 1 of the Notes to Consolidated Financial Statements of
    Koppers.
 
(9) Acquisitions and related capital expenditures for 1995 include
    approximately $35 million related to the acquisition and modernization of
    the Monessen Facility and the acquisition of a wood crosstie treating
    facility in Somerville, Texas; acquisitions and related capital
    expenditures for fiscal year 1996 and the nine-month period ended
    September 30, 1996 each include approximately $40 million related to the
    acquisition of a coal tar distillation facility in Clairton, Pennsylvania.
 
(10) For purposes of calculating the ratio of earnings to fixed charges (i)
     earnings consist of income before taxes, extraordinary items and
     cumulative effects of accounting changes plus fixed charges and (ii)
     fixed charges consist of interest expense incurred excluding amortization
     of deferred financing costs, and 41% of rental payments under operating
     leases (an amount estimated by management to be the interest portion of
     such rentals).

NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS
FOR THE YEAR ENDED DECEMBER 31, 1996

    Koppers Australia acquisition using the straight-line method over a 20
    year period.

(D) To reflect the additional amortization of debt issuance costs over the
    average lives of the related new debt, net of the prior debt issuance
    costs.
 
(E) To record incremental interest expense associated with the
    Recapitalization. The interest expense on the Notes is computed at an

    definitions of EBITDA. Amortization of deferred financing fees is included
    in the Company's financial statements in depreciation and amortization and

 Comparison of Results of Operations for the Nine Months Ended September 30,
1997 and 1996.
 
  NET SALES. Net sales for the nine months ended September 30, 1997 were 2.0%
higher than the same period in 1996. Net sales for Carbon Materials &
Chemicals increased by 4.0% due primarily to sales from the Clairton,
Pennsylvania facility acquired in April, 1996 coupled with increases in
volumes and prices for PAA of 17.6% and 6.9%, respectively. The increase in
net sales of 5.2% for Railroad & Utility Products was due to higher railroad
crosstie revenues, which more than offset a 2.9% reduction in sales volumes
for utility poles. Net sales for Coke Products decreased by 9.8% due to lower
production and shipments primarily as the result of capacity rationalization
at the Woodward, Alabama coke facility ("Woodward Coke Facility").

  GROSS PROFIT AFTER DEPRECIATION. As a percent of net sales, gross profit
after depreciation decreased to 11.8% for the nine months ended September 30,
1997 from 11.9% for the same period last year. Gross margin for Carbon
Materials & Chemicals increased to 18.1% from 16.2% in the prior year
primarily as the result of increases in volumes and pricing of PAA in 1997 as
noted above. Gross margin for Railroad & Utility Products increased to 11.7%
from 10.9% in the prior year primarily as the result of higher revenues for
railroad crossties. Gross margin for Coke Products decreased to (2.6%) from
5.3% due to higher unit costs incurred as the result of reduced production at
the Woodward Coke Facility, coupled with costs associated with unusual returns
and credits issued to customers.
 
  DEPRECIATION AND AMORTIZATION. The increase in depreciation and amortization
for the nine months ended September 30, 1997 as compared to the prior year was
due primarily to the acquisition of the Clairton tar distillation facility in
April 1996 and the Company's ongoing capital expenditures program.
 
  SELLING, GENERAL AND ADMINISTRATIVE EXPENSE. Selling, general and
administrative expense for the nine months ended September 30, 1997 amounted
to 4.8% of net sales, which was consistent with the prior year period, as
lower expenses for legal and consulting services were offset by increases in
employee benefits in 1997.
 
  EQUITY IN EARNINGS OF AFFILIATES. Equity earnings for the nine months ended
September 30, 1997 were $1.7 million lower than the prior year period
primarily as a result of lower earnings from Koppers Australia. The lower
earnings were due to higher maintenance and repair expenses and a stronger
U.S. currency rate in 1997.
 
  OTHER EXPENSE. Other expense for the nine months ended September 30, 1997
consisted of the write-off of $1.4 million of deferred expenses related to the
IPO which was withdrawn in the second quarter. Other expense for the prior-
year period consisted of a litigation charge related to the OCF Settlement.
See Note 11 of the Notes to Consolidated Financial Statements of Koppers.
 
  INCOME TAXES. The effective income tax rate for the nine months ended
September 30, 1997 was 3.1% as compared to (8.1%) in the prior-year period due
to lower income in 1996 as the result of the OCF Settlement and restructuring
charges coupled with the utilization of energy tax credits from the Monessen
Facility. The credit is based on its production of coke as a non-conventional
fuel source and the sale thereof to unrelated third parties. The credit is
available through December 31, 2002 and, based on current production levels at
the Monessen Facility, could provide up to a maximum $10.2 million of tax
credits annually, unadjusted for inflation and assuming full production at the
Monessen Facility, until the credit expires. Use of the tax credits is limited
to the availability of taxable income.
 
  NET INCOME. Net income for the nine months ended September 30, 1997 as
compared to the prior year increased by $16.6 million due primarily to
litigation and restructuring charges taken in 1996.
 
 Comparison of Results of Operations for the Years Ended December 31, 1996 and
1995.
 
  NET SALES. Net sales for the year ended December 31, 1996 were 11.9% higher
than the same period in 1995, due primarily to the effect of acquisitions in
the Carbon Materials & Chemicals and Coke Products businesses. Net sales for
Carbon Materials & Chemicals increased by 21.2% due primarily to sales of
approximately $44 million from the Clairton facility acquired April 1, 1996.
The effect of the acquisition was offset to some extent by a net reduction in
PAA sales due to a 31.9% reduction in average PAA prices. Net sales for
Railroad & Utility Products decreased by 3.3% due to a 12.2% reduction in
sales volumes for utility poles as a result of public utility deregulation and
its impact on maintenance programs and due to disruptions in shipments as a
result of severe weather conditions in the first quarter of 1996. Net sales
for Coke Products increased by 36.5% due primarily to sales of approximately
$44 million from the Monessen Facility in its first full year of operation.
This increase was offset to some extent by a 10.6% reduction in sales at the
Woodward Coke Facility resulting primarily from suspensions of shipments to
U.S. Steel Group, a unit of USX Corporation, (due to an explosion at one of
their blast furnaces) and McLouth Steel Products Corp. (due to its filing of a
bankruptcy
 
                                      38
<PAGE>
 
petition and its cessation of business) in 1996, as well as reduced production
in the first quarter of 1996 as a result of severe weather conditions.
 
  GROSS PROFIT AFTER DEPRECIATION. As a percent of net sales, gross profit
after depreciation decreased to 12.0% for the year ended December 31, 1996
from 12.8% for the prior year. Gross margin decreased to 17.0% from 18.0% for
Carbon Materials & Chemicals and to 10.9% from 12.4% for Railroad & Utility
Products, while gross margin for Coke Products increased to 4.6% from 2.5%.
The decrease for Carbon Materials & Chemicals was due to a 31.9% reduction in
PAA prices, which more than offset the positive margin effect of the Clairton
acquisition. The decrease in gross profit for Railroad & Utility Products was
due to higher unit costs for utility poles as a result of a 12.2% decline in
sales volumes and $0.6 million of costs associated with labor disruptions and
increased operating expenses as a result of severe winter weather in the first
quarter of 1996. The increase for Coke Products was due primarily to higher
coke prices of 2.8% coupled with higher volumes of 33.2%, as an increase in
volumes due to a full twelve months of operations at the Monessen Facility was
partially offset by volume reductions at the Woodward Coke Facility.
 
  DEPRECIATION AND AMORTIZATION. The increase in depreciation and amortization
for 1996 as compared to the prior year was due primarily to the acquisition of
the Clairton tar distillation facility in April 1996, and the Monessen
Facility which started production in November 1995.
 
  SELLING, GENERAL AND ADMINISTRATIVE EXPENSE. Selling, general and
administrative expense for 1996 decreased to 4.7% of net sales from 5.3% of
net sales in the prior year, primarily due to a reduction in management
incentive accruals.
 
  RESTRUCTURING CHARGES. Restructuring charges were comprised of plant closing
charges of $7.4 million, capacity rationalization charges of $5.4 million and
severance charges of $2.6 million. Plant closing charges included $6.5 million
for the Houston carbon materials facility and $0.9 million for the Carrollton,
Ohio refractory materials facility. The plant closing charges consisted
primarily of write-downs of property and equipment, environmental remediation
and severance costs. Capacity rationalization charges of $5.4 million at the
Woodward Coke Facility primarily include property and equipment write-downs.
Severance charges totaling $2.6 million were incurred as a result of workforce
reductions of approximately 90 salaried employees at various field locations
and at corporate headquarters.
 
  EQUITY IN EARNINGS OF AFFILIATES. Equity in earnings of affiliates increased
to $9.6 million for 1996 from $9.2 million in the prior year as higher
earnings from Koppers Australia and KSA (as defined herein) were partially
offset by lower earnings from Tarconord as a result of weaker European market
conditions.
 
  LITIGATION CHARGES. Litigation charges for 1996 consisted of a $10.1 million
charge related to the OCF Settlement and a $2.5 million legal settlement
payment to CSX.
 
  INTEREST EXPENSE. Interest expense increased $1.6 million for 1996 compared
to the prior year primarily as a result of the additional $40.0 million in
indebtedness to finance the acquisition of the Clairton facility.
 
  INCOME TAXES. The effective income tax rate for 1996 was a benefit of
(77.1)% as compared to an effective rate of 29.0% in the prior year as a
result of lower pretax earnings in 1996 coupled with the utilization of a 1996
energy tax credit for the Monessen Facility.
 
  NET INCOME. Net income for 1996 as compared to the prior year decreased by
$10.3 million primarily as a result of $15.5 million of restructuring charges
and $12.6 million of litigation charges. These charges were offset in part by
lower tax expense of $16.1 million in 1996 as compared to the prior year.
Earnings from the recently acquired Monessen Facility and the Clairton
facility were offset by lower PAA prices and the suspension of coke shipments
to U.S. Steel Group and McLouth Steel Products Corp. for the reasons
indicated.

 Comparison of Results of Operations for the Years Ended December 31, 1995 and
1994.
 
  NET SALES. Net sales for the year ended December 31, 1995, were 10.3% higher
than the corresponding period in 1994, as net sales of Carbon Materials &
Chemicals increased by 20.0%, net sales of Railroad & Utility Products
increased by 3.6%, and net sales of Coke Products increased by 10.7%. The
increase in net sales of Carbon Materials & Chemicals for 1995 primarily
reflected a 52.7% increase in PAA prices and a 13.0% increase in carbon pitch
volumes. The increase in net sales of Railroad & Utility Products for 1995
reflected higher sales volumes of 10.7% for railroad crossties primarily as a
result of sales from the newly acquired Somerville facility, offset by a 13.9%
decline in volumes for utility poles. Prices for railroad crossties decreased
2.2%, while pricing for utility poles increased 9.3% in 1995 compared to the
prior year. The increase in net sales of Coke Products was due to a 6.4%
increase in coke prices, as well as a 6.1% increase in coke volumes primarily
due to shipments of coke in November and December from the newly acquired
Monessen Facility.
 
  GROSS PROFIT AFTER DEPRECIATION. As a percent of net sales, gross profit
after depreciation increased to 12.8% in 1995 from 10.8% in 1994. The increase
in Carbon Materials & Chemicals gross margin to 18.0% from 14.9%, coupled with
an increase in Railroad & Utility Products gross margin to 12.4% from 9.8%,
more than offset a decrease in gross margin for Coke Products to 2.5% from
5.9% as compared to the prior year. The increase in gross margin for Carbon
Materials & Chemicals was primarily a result of a 52.7% increase in selling
prices for PAA. This increase was partially offset by a $1.8 million provision
for the effect of a coal tar spill at a Carbon Materials & Chemicals facility.
The increase in Railroad & Utility Products gross margin was primarily a
result of lower raw materials costs coupled with lower freight costs from
logistics improvements and an increase in selling prices for utility poles.
The decrease in Coke Products gross margin for 1995 was primarily a result of
$5.5 million of start-up expenses, which were not capitalized, at the Monessen
Facility in 1995. Excluding the start-up expenses, gross margin would have
increased to 9.4% of net sales, reflecting a 6.4% price increase for coke.
 
  DEPRECIATION AND AMORTIZATION. The increase in depreciation and amortization
in 1995 compared to the prior year was primarily due to approximately $0.8
million of depreciation related to the acquisition of the Somerville facility.
 
  SELLING, GENERAL AND ADMINISTRATIVE EXPENSE. Selling, general and
administrative expense for 1995 increased to 5.3% of sales from 5.1% of sales
in 1994, primarily due to increased management incentive accruals in 1995.
 
  RESTRUCTURING CHARGES. Restructuring charges for 1994 included $2.5 million
related to a voluntary severance plan initiated as part of a general corporate
restructuring. The total charge reflected salaries and benefits for 55
participating employees.
 
  EQUITY IN EARNINGS OF AFFILIATES. Equity in earnings of affiliates increased
to $9.2 million in 1995 from $5.3 million in 1994, primarily as a result of
stronger carbon pitch and chemicals markets in Australia and Europe.
 
  INTEREST EXPENSE. Interest expense for 1995 increased by $1.4 million as a
result of higher average debt levels due to acquisitions coupled with slightly
higher interest rates.
 
  INCOME TAXES. The effective income tax rate for 1995 increased to 29.0% from
28.0% in 1994. The difference between the effective rates and the statutory
rate was primarily a result of earnings in foreign equity affiliates not taxed
in the United States. Income taxes on equity earnings in foreign affiliates
are limited to the amount of cash dividends received.
 
  NET INCOME. Net income for 1995 increased 140.6% compared to net income from
the prior year, due in part to a $1.8 million extraordinary charge for early
extinguishment of debt in 1994, and also as a result of a higher level of
business activity and generally favorable market conditions in 1995 as
detailed in the discussions of sales and gross profit for the businesses.

LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's liquidity needs are primarily for debt service and capital
maintenance. The Company believes that its cash flows from operations and
available borrowings under its bank credit facilities will be sufficient to
fund its anticipated liquidity requirements for the next twelve months. In the
event that the foregoing sources are not sufficient to fund the Company's
expenditures and service its indebtedness, the Company would be required to
raise additional funds.
 
  As of September 30, 1997 on a pro forma basis after giving effect to the
Saratoga Investment and the Recapitalization, the Company would have had $80.0
million of revolving credit availability under the New Credit Facilities for
working capital purposes, subject to restrictions imposed under the Indenture
related to the Notes offered hereby. As of September 30, 1997, $8.5 million of
commitments were utilized by outstanding standby letters of credit.
 
  Cash provided by operating activities totaled $35.6 million for the nine
months ended September 30, 1997, compared to $31.7 million for the same period
last year, as higher earnings and lower working capital requirements in 1997
(excluding legal settlement reserves) were offset to some extent by cash
expenses in 1997 related to 1996 restructuring charges.
 
  Capital expenditures for Koppers were $13.0 million for the nine months
ended September 30, 1997 versus $16.1 million (excluding acquisitions) for the
same period last year, with the decrease in 1997 due primarily to significant
1996 capital improvements at the Stickney PAA plant and the Monessen Facility.
In April 1996, Koppers purchased the coal chemical business of Aristech
Chemical Corporation ("Aristech") located in Clairton, Pennsylvania for
approximately $40.0 million cash and the assumption of certain liabilities.
See Note 3 of the Notes to Consolidated Financial Statements of Koppers.
 
  For the years ended December 31, 1997 and 1998 the Company anticipates
capital expenditures of $26.8 million and $26.3 million, respectively. These
amounts include environmental capital expenditures of $3.8 million and $6.9
million for 1997 and 1998, respectively, with the remaining portions for
capital maintenance and improvements.
 
  Financing activities utilized $24.2 million in cash for the nine months
ended September 30, 1997 compared to providing $21.9 million for the same
period last year. Cash used in 1997 included approximately $20.1 million of
debt repayment; cash supplied by financing activities in 1996 was largely the
result of the $35.0 million term loan for the Clairton acquisition coupled
with a net increase of $15.5 million in the revolving credit facility, used in
part to provide for a $12.0 million term loan repayment and a $12.3 million
purchase of non-voting Common Stock of the Company. See Note 5 of the Notes to
Consolidated Financial Statements of Koppers.
   
  The Company will not receive any proceeds from the Exchange Offer. The net
proceeds from the sale of the Old Notes, combined with net proceeds from the
New Credit Facilities, have been and are being applied to complete the
following transactions: (i) the acquisition of Broken Hill's 50% interest in
Koppers Australia, which occurred on December 1, 1997; (ii) the repayment of
all of the 8 1/2's tendered pursuant to the Offer to Purchase and Consent
Solicitation dated October 20, 1997; (iii) the repayment of the outstanding
indebtedness under the Company's then current term loan and revolving credit
facilities; (iv) the redemption of 1,813,200 shares of non-voting Common Stock
owned by APT Holdings Corporation, an affiliate of Mellon Bank, N.A.; (v) the
redemption, at $17.00 per share, of up to 25% of the shares of Common Stock
owned by the current officers of Koppers and Clayton A. Sweeney and the
redemption of up to 100% of the shares of Common Stock owned by any other
Management Investor within sixty (60) days of the consummation of the offering
and the compliance with any applicable securities laws, at the election of
such individuals, in an aggregate amount not exceeding $15.0 million; (vi) the
redemption of 436,508 non-voting shares of Common Stock from Saratoga Koppers;
and (vii) the payment of related fees and expenses.     
 
 
                                      41

  Restructuring Charges. Restructuring charges for 1996 consisted of $11.4
million and $4.1 million of cash and non-cash charges, respectively. At
September 30, 1997, $6.8 million of the total cash charges had been expended.
 
  Seasonality; Effects of Weather. The Company's quarterly operating results
fluctuate due to a variety of factors that are outside Koppers' control,
including inclement weather conditions, which in the past have affected
operating results. Operations at several of Koppers' facilities have been
halted for short periods of time during the winter months. Moreover, demand
for many of Koppers' products declines during periods of inclement weather. As
a result of the foregoing, the Company anticipates that it may experience
material fluctuations in quarterly operating results.
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
  In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings Per Share," which is required to be adopted on December 31,
1997. At that time, the Company will be required to change the method
currently used to compute earnings per share and to restate all prior periods.
Under the new requirements for calculating primary earnings per share, the
dilutive effect of stock options will be excluded. The impact of Statement 128
on the calculation of earnings per share for the nine months ended September
30, 1997 and September 30, 1996 is not expected to be material.
 
  Additionally, the following statements have been issued during 1997 and are
effective for fiscal years beginning after December 15, 1997:
 
  Statement No. 129, "Disclosure of Information about Capital Structure",
requires additional disclosures about an entity's capital structure.
 
  Statement No. 130, "Reporting Comprehensive Income", requires enterprises to
classify items of comprehensive income by their nature in a financial
statement and display the accumulated balance of other comprehensive income
separately from retained earnings and additional paid-in-capital.
 
  Statement No. 131, "Disclosure about Segments of an Enterprise and Related
Information" changes the way companies report segment information in annual
reports and in interim financial statements.
 
  The Company does not expect the effect of adoption of Statements No. 129,
130 or 131 to be material.
 
ENVIRONMENTAL MATTERS
 
  Like companies involved in similar environmentally sensitive businesses, the
Company's operations and properties are subject to extensive Environmental
Laws. The Clean Air Act and Clean Water Act, each as amended, impose stringent
standards on air emissions and water discharges, respectively. Under RCRA, a
facility that treats, stores or disposes of hazardous waste on-site may be
liable for corrective action costs, and a facility that holds a RCRA permit
may have to incur costs relating to the closure of certain "hazardous" or
"solid" waste management units. Under CERCLA and similar state laws, an owner
or operator of property at which releases of hazardous substances have
occurred may be liable for investigation and remediation of any resulting
contamination and related natural resource damages. In addition, under CERCLA,
the generator of hazardous substances may be strictly, and jointly and
severally liable for any required investigation or remediation at third-party
disposal sites and related natural resource damages. The Environmental Laws
are subject to frequent amendment. The sanction for failure to comply with
such Environmental Laws can include significant civil penalties, criminal
penalties, injunctive relief and denial or loss of, or imposition of
significant restrictions on, environmental permits. In addition, the Company
could be subject to suit by third parties in connection with violations of or
liability under Environmental Laws.
 
  In March 1996, Jefferson County issued a notice of violation in connection
with various alleged violations of air pollution control regulations regarding
emissions from coke oven batteries at the Woodward Coke Facility. In February
1997, the US-EPA issued a notice of violation covering the same issues.
Thereafter, Koppers
 
                                      42
<PAGE>
 
discovered that certain benzene abatement equipment at this facility had not
been operational for several months. Koppers and Jefferson County have
negotiated a settlement agreement which includes both the original Jefferson
County notice of violation and the self-reported benzene abatement violation,
and requires Koppers to pay a civil penalty in the amount of $450,000, which
sum has been paid. There can be no assurance that the settlement with
Jefferson County will deter the US-EPA from pursuing its notice of violation.
Following a preliminary investigation of the Woodward Coke Facility, Koppers
also discovered that certain environmental reports and records required under
the Clean Water Act contained incomplete and inaccurate information and that
certain environmental reports and certifications were not filed when required.
Corrected reports have been submitted to Jefferson County, the State of
Alabama and the US-EPA. In June 1997, during a routine environmental
compliance audit of the Logansport Wood Treating Facility, it was discovered
that certain records and reports required under the Clean Water Act contained
incomplete and inaccurate information. Corrected reports have been submitted
to the local municipality, the State of Louisiana and the US-EPA. Although no
notice of violation has been issued in conjunction with this issue, it is
likely that such a notice will be issued and substantial penalties sought by
the regulatory authorities. On April 25, 1997, Koppers was served with notices
of violation by Pa-DEP which alleged that Koppers was in violation of a Pa-DEP
plan approval for the Monessen Facility regarding nitrogen oxide emissions and
failed to conduct timely emission-monitoring testing on Monessen Facility
boilers. Koppers could be subject to significant liability in connection with
each of these matters, including injunctive relief, substantial civil and
criminal penalties and the risk of third-party lawsuits. Resolution of these
and other pending compliance matters could have a material adverse effect on
the business, financial condition, cash flow and results of operations of the
Company.
 
  For each of the last three fiscal years, the Company's average capital
expenditures and operating expenses for environmental matters, including
depreciation, amounted to approximately $7.0 million and $16.0 million,
respectively. The Company believes that environmental operating costs as a
percentage of total operating costs will not change materially from those
incurred during the past three years. The Company currently estimates that
capital expenditures in connection with matters relating to environmental
control will be approximately $3.8 million and $6.9 million for 1997 and 1998,
respectively. Because Environmental Laws have historically become
increasingly more stringent, costs and expenses relating to environmental
control and compliance may increase in the future. Also, Koppers may have to
incur additional capital expenditures and compliance costs (which it is unable
to estimate at this time) in connection with the resolution of the
aforementioned notices of violations. As such, there can be no assurance that
costs of compliance with existing and future Environmental Laws will not
exceed current estimates and will not have a material adverse effect on the
Company's business, financial condition, cash flow and results of operations.
 
  Under the terms of the Asset Purchase Agreement between Koppers Industries,
Inc. and Old Koppers (now known as Beazer East, Inc.) at the formation of the
Company in 1988, Beazer East assumed the liability for and indemnified Koppers
against (among other things) cleanup liabilities for contamination occurring
prior to the purchase date at sites acquired from Beazer East, and third-party
claims arising from such contamination in the Indemnity. Beazer East's
performance of the Indemnity is unconditionally guaranteed by Beazer Limited
under the Beazer Guarantee. Contamination identified at sites owned and/or
operated by Koppers is being investigated and remediated under CERCLA, RCRA or
state cleanup programs. Currently, at the sites acquired from Beazer East
(which include all of the CERCLA sites and all but one of the RCRA sites),
substantially all investigation and remediation activities are being conducted
and paid for by Beazer East pursuant to the terms of the Indemnity; however,
there can be no assurance that Beazer East and Beazer Limited will continue to
meet their obligations. In the event they do not, Koppers may be required to
pay such costs which are believed to have averaged approximately $13.0 million
per year for the last three years. In addition, the government and other third
parties have the right under applicable Environmental Laws to seek relief
directly from Koppers for any and all such costs and liabilities. The
requirements to pay such costs and assume such liabilities without
reimbursement would have a material adverse affect on the business, financial
condition, cash flow and results of operations of the Company. Furthermore, if
Koppers were required to record a contingent liability in respect of
environmental matters covered by the Indemnity on its balance sheets, the
result could be that the Company would have significant negative net worth.

  The Indemnity does not afford Koppers indemnification against environmental
costs and liabilities relating to activities or conditions occurring or
arising 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 post-closing acquisitions. At the Clairton
facility, the Somerville facility and the Monessen Facility (each of which
Koppers acquired subsequent to the acquisition of the Beazer East sites),
investigations and remediations are being performed. All applicable
indemnification obligations are being honored at the Clairton and Somerville
facilities and Koppers believes that the sellers (or their predecessors) at
both of these facilities will continue to conduct and finance most activities
directly. Although the Company is not aware of any reason why such
environmental indemnification obligations will not be performed, if Koppers
were required to pay costs associated with these two sites, it could have a
material adverse effect on the Company's business, financial condition, cash
flow and results of operations. At the Monessen Facility, Koppers has entered
into the Monessen Consent Order with Pa-DEP pursuant to which the Koppers'
liabilities for environmental cleanup have been capped at $550,000 for matters
identified pursuant to the Monessen Consent Order. Although an environmental
indemnification was provided to Koppers by the seller of that facility, the
Company does not expect that such obligations will be honored. If
contamination at the Monessen Facility should be discovered which is not
identified pursuant to the Monessen Consent Order or if the US-EPA should
require cleanup above the $550,000 "cap" contained therein, costs associated
with such events could have a material adverse effect on the Company's
business, financial position, cash flow and results of operations. See
"Business--Environmental Matters."
 
OTHER MATTERS
 
  As a result of an internal investigation, the Company discovered in March
1997 that certain reports relating to the moisture of coke contained
incomplete and inaccurate information. Because of these discrepancies, certain
customers who purchased the coke were overbilled. Upon discovery of the
overbilling, refunds were made available to all the affected customers.
 
  For a fee, the Company treats waste water produced by Beazer East during
Beazer East's remediation of certain of the Company's facilities. Beazer East
performs these remediation activities pursuant to the Indemnity. During the
summer of 1997, Beazer East challenged the amounts of the charges for waste
water treatment services at the Florence and Follansbee facilities. Beazer
East alleged they had been overcharged by approximately $2.2 million at
Florence and by approximately $3.1 million at Follansbee. The Company has
contested these allegations and believes that if an overcharge occurred, the
amount of the overcharge is less than Beazer East has alleged.
 
  Due to the advanced ages of the coke oven batteries, ongoing environmental
compliance issues and significant capital expenditure requirements, all of
which have combined to reduce productive capacity and increase per unit costs,
the Company's Board of Directors has authorized the Company to close the
Woodward Coke Facility in early 1998. This will result in a charge to earnings
in the fourth quarter of 1997 of approximately $38.5 million, $9.4 million of
which will be cash charges primarily for dismantling and severance costs.
Sales and gross profit (loss) at the Woodward Coke Facility for the twelve
months ended September 30, 1997 amounted to $58.1 million and ($6.1) million,
respectively. Capital expenditures and depreciation for the twelve months
ended September 30, 1997 amounted to $3.4 million and $4.4 million,
respectively.
 
  The Feather River, California Utility & Construction Products facility
("Feather River") includes both a wood treating and now-dormant wood-fired
cogeneration facility. The Company has found it difficult to compete in the
California utility pole market due to Feather River's limited treatment
capabilities, a shrinking product demand and the high cost of raw materials.
The Company has recently been notified that a targeted customer for Feather
River will not take product in 1998, which will impact the forward-looking
profitability of this facility. The Company is currently conducting an
analysis to determine the feasibility of continuing to operate this facility;
this analysis is expected to be completed by the end of 1997. The current
carrying value of assets at this
 
                                      44
<PAGE>
 
facility is approximately $4.3 million. The Feather River cogeneration
facility has been dormant for three years while the Company explored potential
opportunities for developing a treated wood burning and disposal facility. The
Company has been unable to locate a customer for this process, and expects to
make a decision regarding the future of the facility by the end of 1997. In
the event that a decision is made to close the cogeneration facility, this
could result in a charge to earnings in the fourth quarter of approximately
$1.9 million, which includes a $1.6 million early contract termination fee
with the local utility.

                                   BUSINESS
 
  The Company is a leading integrated producer of carbon compounds and treated
wood products for use in a variety of markets including the chemical,
railroad, aluminum and steel industries. The "Koppers" name has been
associated with the carbon compounds and wood treating businesses for over 70
years and the Company has a leading position in most of its markets. The
Company operates 22 facilities in the United States and 14 in the South
Pacific (primarily in Australia and New Zealand), and maintains indirect
ownership interests in an additional facility in the United States through its
domestic joint venture KSA (as defined herein) and in five facilities overseas
through Tarconord. The Company recorded net sales and Adjusted EBITDA of
$717.6 million and $95.8 million, respectively, for the twelve months ended
September 30, 1997. For the same periods, the Company's businesses, Carbon
Materials & Chemicals, Railroad & Utility Products, Coke Products and Koppers
Australia, accounted for 34%, 35%, 14% and 17% of pro forma net sales,
respectively.
 
  Through its Carbon Materials & Chemicals division, Koppers is the largest
coal tar processor in North America. Koppers' Carbon Materials & Chemicals
division processes coal tar into a variety of intermediate products, including
carbon pitch, PAA and creosote, which are basic materials necessary in the
production of aluminum, polyester resins and plasticizers, and the pressure
treatment of wood, respectively. Koppers' Railroad & Utility Products division
is the largest supplier of treated wood products, such as railroad crossties
and utility poles, to United States railroads and the electric and telephone
utility industries. Koppers' Coke Products division converts coal into coke
for sale to integrated steel producers and foundries that use coke in the
production of iron and steel.
 
  Products and services provided by Koppers Australia are similar to those
provided by Koppers. Koppers Australia is Australia's largest manufacturer of
carbon pitch, wood preservatives and treated wood products and it markets
these products, as well as carbon black, in Australia, New Zealand and other
Pacific Rim nations. Koppers Australia is the only coal tar distiller in
Australia, providing it with a significant competitive advantage in serving
the Australian aluminum smelting industry.
 
BUSINESS STRATEGY
 
  The Company's strategy includes: (i) improving productivity; (ii)
implementing additional cost reduction initiatives; (iii) developing,
marketing and selling new products; and (iv) broadening its customer base in
new and existing markets.
 
  In the Carbon Material & Chemicals division, the Company is currently
developing improved pitches for the aluminum industry, specialty coal tar
pitches to be used in electrode carbon markets and additional downstream
applications for naphthalene in the super-plasticizer and other specialty
chemical markets. The Company's strategy in the railroad industry is to be the
largest volume supplier of high quality treated wood products, track
maintenance and construction products and services. The Company will continue
to review opportunities to increase capacity at several of its treating
facilities and to expand services offered to railroad customers, such as
plant-assembled track sections, freight car cleaning and used tie disposal. In
Australia, New Zealand and the Far East, the Company intends to expand its
access to coal tar feedstocks and soft pitches with a focus on China and other
emerging markets.
 
COMPETITIVE STRENGTHS
 
  Strong Customer Relationships--The Company's reputation has enabled it to
include among its customers numerous companies preeminent in their respective
markets, including Alcoa, CSX, LTV and UCAR. In order to enhance these
relationships, the Company has in place programs to ensure quality and
customer satisfaction. In addition, the Company's facilities are strategically
located to service its customers' requirements.
 
 
                                      46
<PAGE>
 
  Broad Product Line--The Company sells a wide variety of products to a
diverse customer base, including steel producers, aluminum smelters,
railroads, utilities, rubber tire producers, wood treaters, producers of
polyester resins, paints, coatings and plasticizers, the roofing industry and
pavement sealer manufacturers. The Company's broad product line and customer
base allow it to reduce its exposure to any one market segment.
 
  Long-Term Sales Contracts--Historically, the Company has sought to reduce
its exposure to the cyclicality of its customers' businesses and general
economic conditions by securing commitments for a large portion of its planned
production through annual and multi-year contracts. In each of the last five
years, the Company has been able to secure over 50% of the following year's
sales through such contracts.
 
  Global Presence--The Company, along with its joint venture in Denmark,
Tarconord, serves the North American, European, Asian and Australian markets
with carbon materials and chemical products. The Company works closely with
Tarconord on marketing strategy, raw material sourcing and technology sharing.
The Company and Tarconord have completed several acquisitions and have entered
into marketing agreements enabling the Company to expand its presence into new
and emerging markets, including the United Kingdom, People's Republic of China
and other Pacific Rim nations.
 
  Diversified Supply Base--The Company believes that its ability to source
high-quality coal tar, wood and coal from multiple suppliers provides it with
a significant competitive advantage in meeting customer requirements in a
timely and economically advantageous manner. In addition, the Company believes
its ability to source coal tar globally is critical to obtaining the quality
of coal tar needed to satisfy its global customers' needs.
 
  Vertical Integration--The Company's ability to utilize, in its manufacturing
processes, products produced in its Carbon Materials & Chemicals and Coke
Products divisions provides the Company with significant cost savings. The
Company also believes it has a significant cost advantage over its competitors
as a result of its ability to use internally generated naphthalene as a
primary feedstock in the production of PAA. All of the Company's domestic
competitors currently use orthoxylene, which is generally a higher-cost
feedstock than naphthalene, in the production of PAA. Another example of
vertical integration is that creosote, a major by-product of the coal tar
distillation process, is used as a raw material in the treatment of wood by
the Company's Railroad & Utility Products division.
 
  Tax Credits--The Monessen Facility qualifies for a tax credit based on its
production of coke as a non-conventional fuel source and the sale thereof to
unrelated third parties. The credit is available through December 31, 2002
and, based on current production levels at the Monessen Facility, could
provide up to $10.2 million of tax credits annually, unadjusted for inflation
and assuming full production at the Monessen Facility, until the credit
expires. Use of the tax credits is limited to the availability of taxable
income. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Results of Operations." The Company may monetize all or
some portion of these tax credits.
 
INDUSTRY OVERVIEW
 
 CARBON MATERIALS & CHEMICALS
 
  The coal tar distillation business involves the conversion of coal tar, a
by-product of the transformation of coal into coke, 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%), creosote
oils (approximately 30%) and chemical oils (approximately 20%). The most
critical element in producing high quality tar products is the ability to
obtain and blend multiple coal tars, with various specifications, from several
sources in order to achieve the consistent properties desired by the customer.
 
  The aluminum industry is the largest user of carbon pitch, which acts as a
binding material for the anodes used in the electrolysis process required in
aluminum smelting. Because all coal tar products are produced in
 
                                      47
<PAGE>
 
relatively fixed proportion to carbon pitch, the level of carbon pitch
consumption generally determines the level of production of other coal tar
products. The commercial carbon industry, the second largest user of carbon
pitch, uses carbon pitch to produce electrodes and other specialty carbon
products for the steel industry. Management estimates that the United States
aluminum and specialty carbon markets consumed approximately 600,000 tons of
carbon pitch in 1996.
 
  Creosote is used in the wood preservation industry as a preservative for
railroad crossties and lumber, utility poles and pilings. Approximately two-
thirds of the total United States market requirements are used for railroad
construction and maintenance, with the remainder used primarily for utility
poles and pilings. To the extent that creosote cannot be sold for use in
treating wood products, distillate oils are sold into the carbon black market
rather than being blended to creosote specifications. Management estimates
that the North American wood treating industry used approximately 620 million
pounds of creosote in 1996. The Carbon Materials & Chemicals division sold
approximately 283 million pounds of creosote in 1996, 34% of which was sold to
the Railroad & Utility Products division. An additional 36% of Koppers'
creosote production was sold to three Class 1 railroad customers, all of which
take delivery of the creosote at Koppers' wood treating facilities.
 
  Chemical oils resulting from the distillation of coal tars are further
refined into naphthalene, which is the primary feedstock used by the Company
for the production of PAA. The primary markets for PAA are in the production
of flexible vinyl, polyester resin and alkyd resin. Roofing pitch and refined
tars are also produced in smaller quantities and are sold into the commercial
roofing and pavement sealer markets, respectively.
 
  Because of the Clean Air Act Amendments and other Environmental Laws, future
coal tar availability from United States coke production is expected to
decline. Management believes that the Company's ability to source coal tar and
carbon pitch from overseas markets, as well as its research of petroleum
feedstocks, will assist in securing an uninterrupted supply of coal tar. See
"Risk Factors."
 
 RAILROAD & UTILITY PRODUCTS
 
 Railroad Products & Services
 
  The major product of Railroad Products & Services is pressure-treated wood
crossties. Treated crossties are used in railroad track maintenance programs.
Approximately 15 million crossties are replaced by railroads every year.
United States Class 1 railroads (defined as the nine largest railroad systems
in the United States) maintain approximately 177,000 miles of track, estimated
to contain 540 million crossties. In addition to crossties, the division also
offers services to the railroads, such as assembling 39-foot track panel
sections, pre-plating ties, cleaning debris from cars, and disposing of
discarded ties in an environmentally safe manner.
 
  Historically, investment trends in track maintenance by railroads have been
linked to general economic conditions in the country. During recessions, the
railroads have typically deferred track maintenance until economic conditions
improve. Demand has been relatively stable since 1993. Recently, several of
the major Class 1 railroads have merged. Management believes these mergers
will not have an adverse effect on the future demand for crossties.
 
  Hardwoods, such as oak and other species, are the major raw materials in
wood crossties. Hardwood prices, which account for approximately 60% of a
finished tie'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. Creosote, the preservative used to treat
crossties, accounts for approximately 10% of the finished tie's cost.
 
  Hardwood lumber is procured by the division from hundreds of small sawmills
throughout the northeastern, midwestern, and southern areas of the country.
The ties are shipped via rail car or trucked directly to one of the
 
                                      48
<PAGE>
 
division's thirteen treating plants, all of which are on line with a major
railroad. The ties are either air-stacked for a period of six to twelve months
or artificially dried by a process called boultonizing. Once dried, the ties
are pressure treated with creosote, a product of Koppers' Carbon Materials &
Chemicals division.
 
  The Class 1 railroads have demonstrated a desire to outsource their non-core
business activities. This desire, coupled with Koppers' long-standing
relationships with the Class 1 railroads, has positioned the Company for a new
growth opportunity. The Company is now offering new services to the railroads
at a cost lower than the railroads' internal cost, and the Company believes
that there is an opportunity for future growth in such related areas.
 
 Utility & Construction Products
 
  The Utility & Construction Products division treats utility poles and timber
piling for sale to electric utilities, telephone companies and the
construction industry. These products are produced from pine or fir trees. The
trees are cut to length and shipped to peeling locations at one of the
Company's seven treating facilities or a third party's site. The poles are
then either dried in kilns or put directly into treating cylinders
(autoclaves) and steam conditioned before treatment. Kiln drying and steam
conditioning are processes that remove the water from the wood before
treatment. The applicable preservative is then injected into the wood under
pressure, after which a vacuum is used to remove any excess chemical.
 
  Over the last two years, overall pole demand has dropped as utilities have
reduced non-essential spending in anticipation of competitive pressure arising
from deregulation. It is expected that deregulation will affect both new and
replacement pole installation markets for the next several years.
 
  Pricing of raw materials has been significantly impacted over the last five
years due to a shortage of supply. Douglas fir availability has been affected
by logging restrictions on public land, resulting in increased demand for
southern yellow pine. According to Southern Pressure Treaters Association
statistics, pole prices have gone up over 65% during the last five years.
 
 COKE PRODUCTS
 
  Coke is a carbon and fuel source required in the manufacture of steel and
iron. 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 the case of the Company, operate independently
and are known as "merchant producers."
 
  Coke is consumed in three markets: steel mill blast furnaces, foundries and
other industrial operations. There are two basic types of coke which are
produced: furnace coke and foundry coke. Furnace coke, which is produced from
different coal blends and requires different heating periods than foundry
coke, is generally formed in smaller pieces than foundry coke and is used in
blast furnaces to make steel by acting as a reducing agent for the iron ore.
Foundry coke generally has higher prices and is used predominantly by
automobile and pipe manufacturers in the metal-forming process. Imports are a
relatively small factor in the foundry coke market because of difficulties in
shipping and limited sources of high-quality imports, but imports of furnace
coke have become more significant over the past three years.
 
  Coal is transformed into coke by a process beginning with the pulverizing,
blending and mixing of various types of coal to produce coke with the
appropriate chemical and physical specifications. The coal mixture is baked
approximately 18 hours for furnace coke and 28 hours for foundry coke at
temperatures reaching 2,000 degrees fahrenheit and is subsequently quenched
and screened in accordance with contract specifications before being loaded
for shipment. Volatile constituents, including gases, chemicals and coke-oven
tar, are extracted and sold for a variety of industrial uses, with a portion
of the gas being returned to the coking chambers as heating fuel.
 
                                      49
<PAGE>
 
  The quality of coke is determined by its chemical and physical properties. A
high percentage of fixed carbon and low levels of sulfur, ash, and other
volatile matter are essential to the effectiveness of coke in the iron and
steel manufacturing processes. The most important physical properties of coke
are its ability to withstand breakage and its resistance to abrasion during
handling and use in blast furnaces and foundries.
 
  Domestic coke production capacity has decreased over the last ten years due
to high capital costs for coke oven maintenance and rebuilding, high operating
costs and expenditures resulting from new environmental compliance standards.
As a result of the decrease in coke industry capacity, industry operating rates
have improved significantly over the past decade and the Company believes most
domestic coke producers operated at or near their effective capacities in 1996.
Several of the large integrated steel companies have shut down or announced
plans to close their coke batteries, reducing domestic capacity. The reduction
of United States coke production capacity is expected to continue. Integrated
steel producers are employing various methods to displace a portion of the coke
use in steel production to reduce their reliance on existing suppliers and
decrease raw materials costs. In some cases, companies have been successful in
replacing a portion of their demand for coke with pulverized-coal-injection
technology.
 
MANUFACTURING PROCESSES
 
  The Company's operations are, to a substantial extent, vertically integrated
and employ a variety of processes as illustrated in the following flow diagram:




                            [Diagram appears here]

 

                                       50
<PAGE>
 
CARBON MATERIALS & CHEMICALS
 
  The Company's Carbon Materials & Chemicals division manufactures three
principal products: carbon pitch, PAA and creosote. These products, used in
the production of aluminum, steel, flexible vinyl, polyester resins and the
treatment of wood, respectively, are produced through the distillation of coal
tar, a by-product of the transformation of coal into coke. The Company
believes that, together with Tarconord, it is one of the two largest producers
of carbon pitch in the world. The Carbon Materials & Chemicals division's
profitability is impacted by its cost to purchase coal tar in relation to its
prices realized for carbon pitch, creosote and PAA. The Company has five
operating facilities in the United States strategically located to provide
access to coal tar and to facilitate better service to its customers with a
consistent supply of high-quality products. For 1996, sales of carbon pitch,
PAA and creosote (to outside customers only) accounted for approximately 43%,
21% and 10% of the Carbon Materials & Chemicals division's net sales,
respectively. Other significant products include roofing pitches and related
products (11%), refined tar (4%), and other chemical and tar products (8%).
 
  The Company believes it has a strategic advantage over its competitors based
on its ability to access coal tar from many United States and foreign
suppliers and subsequently blend such coal tars to produce carbon pitch with
the consistent quality important in manufacturing quality anodes for the
aluminum industry. The Company's four coal tar distillation facilities and one
carbon pitch melting facility give it the ability to offer customers multiple
sourcing and consistent supply of high quality products. In anticipation of
potential shutdowns of United States coke capacity, the Company has secured
coal tar supply through long-term contracts and acquisitions. The Company also
benefits from its ability to use a carbon pitch by-product, naphthalene, as a
low-cost feedstock for PAA production and from its ability to sell a large
portion of its creosote production internally to the Railroad & Utility
Products business.
 
                                      51
<PAGE>
 
  The following flow diagram illustrates the manufacturing processes in the
Carbon Materials & Chemicals division and shows the approximate percentage
yield for each gallon of coal tar distilled:

                            [Diagram appears here]
 
 
  Koppers' sales volume of carbon pitch increased from 263,000 tons in 1993 to
364,000 tons in 1996, an increase of 38% due to improved aluminum market
conditions and the acquisition of the Clairton facility in April 1996. Overall,
pricing has trended moderately upward from 1993 through September 30, 1997.
Over 75% of Koppers' carbon pitch is sold to the aluminum industry under long-
term contracts ranging from three to seven years. Demand for carbon pitch has
fluctuated historically with United States' production of primary aluminum.
There are currently no known viable substitutes for carbon pitch in the
production of carbon anodes. The Carbon Materials & Chemicals division's two
largest customers represented approximately 20% of the division's net sales for
1996. The Company's three main competitors in North America in the production
of carbon pitch are AlliedSignal, Inc., VFT Canada, and Reilly Industries, Inc.
 
  On a worldwide basis, naphthalene and orthoxylene, a petroleum derivative,
can both be used in the manufacturing of PAA and are considered to be
interchangeable. In the United States, however, the Company is the only PAA
producer capable of utilizing both orthoxylene and naphthalene in its
manufacturing process, with naphthalene being a generally lower cost feedstock.
Koppers' price realizations and profit margins for PAA have
 
                                       52
<PAGE>
 
historically fluctuated with the price of orthoxylene and its relationship to
Koppers' cost to produce naphthalene. Although the price of orthoxylene was
relatively stable prior to 1994, due to increased demand, the price of
orthoxylene increased from $0.14 per pound in March 1994 to $0.38 per pound in
May 1995. As a result, PAA prices increased by approximately 101% during that
period, providing Koppers with a significant cost advantage over its
competition and a temporary expansion of margins. In 1996, however, the
average price for orthoxylene declined to approximately $0.16 per pound,
resulting in a corresponding decline in PAA prices and margins. At September
30, 1997, orthoxylene prices were $0.19 per pound. Koppers' cost to produce
naphthalene and PAA is primarily driven by its cost to procure coal tar.
Koppers' four principal PAA competitors, Exxon Chemical Company, Aristech,
BASF Corporation and Stepan Company, can use only orthoxylene in the
production of PAA.
 
  Approximately 34% of Koppers' creosote production is sold to the Railroad &
Utility Products division. An additional 30% is sold to three Class 1 railroad
customers, all of which take delivery of the creosote at one of Koppers' wood
treating facilities. Over the last eight years, the Railroad & Utility
Products division purchased all of its requirements of creosote from the
Carbon Materials & Chemicals division, providing it with a competitive
advantage. Koppers is the only competitor in this market that is integrated in
this fashion. The remainder of its creosote materials are sold to railroads,
to other wood treaters or into the carbon black market as a component in the
manufacture of rubber tires. Principal competitors in the creosote market are
AlliedSignal, Inc. and Reilly Industries, Inc.
 
  Coal tar is purchased from a number of outside sources as well as Koppers'
Woodward Coke Facility and Monessen Facility. Primary suppliers are Bethlehem
Steel Corporation, LTV, USX Corporation and Wheeling-Pittsburgh Steel
Corporation. The Woodward Coke Facility currently provides approximately 3% of
Koppers' coal tar, and the Monessen Facility provides approximately 2%. On an
annual basis, Koppers distills approximately 150 million gallons of coal tar
representing approximately 76% of designed capacity. Other Carbon Materials &
Chemicals products include roofing pitch, used in the construction of built-up
roofing systems, and refined tars, sold to manufacturers of pavement sealers
for driveways and parking lots.
 
  Koppers Australia and Tarconord are major regional producers of carbon pitch
and related products and are strategically important to the Company because
they enable the Company to access global markets for its carbon pitch and
related products.
 
RAILROAD & UTILITY PRODUCTS
 
  The Company believes it is the largest supplier of treated wood crossties
and poles in the world. The Company markets these products almost exclusively
to the railroad and public utility markets, primarily in the United States and
Australia. The Railroad & Utility Products division's profitability is
primarily influenced by the demand for railroad products and services by Class
1 railroads, demand for transmission and distribution poles by electric
utilities and its cost to procure wood. Historically, sales of railroad
products and services have represented approximately two-thirds of the
Railroad & Utility Products division's net sales. Railroad products include
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 pilings used in
industrial foundations, beach housing, docks and piers. The Railroad & Utility
Products division operates 15 wood treating plants and 13 pole distribution
yards located throughout the United States, and the Company also has one used
crosstie burning cogeneration plant. The Company's network of plants is
strategically located near timber supplies to enable it to access raw
materials and service customers effectively. In addition, Koppers' crosstie
treating plants abut railroad customers' track lines, and its pole
distribution yards are located near Koppers' utility customers in the
northeast and midwest regions of the United States.
 
 Railroad Products & Services
 
  The Railroad Products & Services business supplies treated crossties and
other products and services to the United States railroad industry. Koppers
has an estimated 47% share of the United States market for treated wood
 
                                      53
<PAGE>
 
products sold to the railroad industry. The Railroad Products & Services
division's largest customer base is the Class 1 railroad market which buys 84%
of all crossties produced in the United States. Koppers is also expanding key
relationships with the approximately 500 short-line and regional rail lines.
The railroad crosstie market is a mature market with approximately 15.2
million replacement crossties purchased per year. The demand for crossties is
only partially affected by economic conditions and has been relatively stable
since 1993. In 1996, Koppers treated approximately 6.3 million crossties for
its Class 1 railroad customers. The Company currently has contracts with eight
of the nine United States Class 1 railroads and has enjoyed long-standing
relationships, some of more than 50 years, with this important customer base.
These relationships, coupled with a growing interest on the part of railroads
to outsource non-core activities, have enabled the Company to position itself
for growth by offering new services to railroads at a cost lower than the
railroads' internal cost. Such new services include assembling 39-foot track
sections and affixing fastening devices at the treating plant rather than
field locations; removing debris from railroad freight cars; and disposing of
discarded ties in an environmentally safe manner in high temperature boilers.
In 1996, approximately 8% of Railroad Products & Services' net sales were
derived from these types of services to railroads. The Company intends to
capitalize on its relationships with railroads by expanding its current
service offerings, including track panels, car cleaning and railroad tie
disposal that fit with its strategic plan.
 
  Koppers' top-10 railroad accounts, which comprised approximately 53% of
Railroad & Utility Products net sales for 1996, are serviced through long-term
contracts ranging from one to twelve years on a requirements basis. CSX
accounted for 15% of Railroad & Utility Products net sales for 1996 and has a
five-year treating agreement with the Company, expiring in December 2001,
which calls for a minimum treating volume of 1.8 million crossties annually.
Koppers' sales to the railroad industry are coordinated through its office in
Pittsburgh, Pennsylvania. The Company's principal competitor in the railroad
products market is Kerr-McGee Chemical Corp.
 
  Hardwood lumber accounts for approximately 60% of a finished crosstie's
cost. The Company obtains its hardwood supply from hundreds of small sawmills
throughout the northeastern, midwestern and southern areas of the United
States. Hardwood prices fluctuate with demand from competing hardwood lumber
markets such as flooring and pallets. In 1993, the price of hardwood increased
significantly, which resulted in a temporary reduction of the Company's
margins. The wood is taken by either truck or rail from Company-operated
collection points directly into its treating plants, where it is pressure
treated with creosote, a product of the Carbon Materials & Chemicals division.
Over the last eight years, the Railroad & Utility Products division purchased
all of its creosote requirements from the Carbon Materials & Chemicals
division. In addition, several railroads procure their own raw materials and
ship them into the Company's plants for treating services. Historically, over
three-fourths of the Company's net sales to railroads have been based on
annual or multi-year contracts.
 
  The Company believes that the threat of substitution for the wood crosstie
is low due to the higher cost of alternative materials. Concrete ties,
however, have been identified by the railroads as a feasible alternative to
wood crossties in limited circumstances. In 1991, the Company acquired a 50%
partnership interest in KSA, a concrete crosstie manufacturing facility in
Portsmouth, Ohio, in order to take advantage of this growth opportunity. In
1996, an estimated 1.1 million concrete crossties, or 7% of total tie
insertions, were installed by Class 1 railroads. The Company believes that
concrete ties will continue to command approximately this level of market
share. This facility produced approximately 150,000 concrete crossties in
1996, or 12% of the U.S. estimated concrete tie market. While the cost of
material and installation of a concrete tie is much higher than that of a wood
tie, the average life of wood and concrete ties are similar, although concrete
generally performs better in high weight bearing, high traffic areas and is
attractive to railroads for these purposes.
 
 Utility & Construction Products
 
  Koppers believes it is the largest domestic producer of treated wood pole
products. The Company's strategy is to maintain its position as the industry
leader in the supply of utility poles, offering the highest quality products
and services, while continuing to cut costs.
 
                                      54
<PAGE>
 
  Utility poles are produced mainly from softwoods such as pine and fir, which
have been subject to steady price increases in recent years due primarily to
increased demand for softwood materials in the paper and construction
industries. The majority of the softwood used for poles is purchased from
large timber owners and individual landowners and shipped to one of the
Company's pole-peeling facilities. While crossties are treated exclusively
with creosote, the Company treats poles with a variety of preservatives
including pentachlorophenol ("Penta"), chromated copper arsenate ("CCA") and
creosote.
 
  The market for utility pole products is characterized by a large number of
smaller, highly competitive producers selling into a price-sensitive industry.
The utility pole market is highly fragmented with over 300 investor-owned
electric and telephone utilities and 1,800 smaller local utilities and Rural
Electric Associations ("REAs"). Approximately 2.4 million poles are purchased
annually. In 1996 and 1997, the Company has seen its utility pole volumes
decrease due to industry deregulation and its impact on maintenance programs.
The Company expects demand for utility poles to remain at lower levels for the
next several years.
 
  In 1996, pole products accounted for approximately 31% of Railroad & Utility
Products net sales. Koppers' sales to its ten largest pole customers accounted
for approximately 8% of Railroad & Utility Products net sales for 1996.
Principal competitors in the utility products market are McFarland Cascade,
North Pacific Lumber and Atlantic Wood Industries Inc. There are few barriers
to entry in the utility products market, estimated by the Company to consist
of mostly regional, wood treating companies which typically operate small to
medium size plants and serve local clients.
 
COKE PRODUCTS
 
  The Company operates the Woodward Coke Facility and the Monessen Facility,
which have an aggregate annual coking capacity of approximately 800,000 tons.
For 1996, furnace coke comprised approximately 78% of total Coke Products net
sales, foundry coke 9%, other coke 8%, and by-products the remaining 5%.
 
  The Company's Woodward Coke Facility produces furnace and foundry coke as
well as coal tar and other related chemicals. The Woodward Coke Facility
consists of 138 ovens arranged in three batteries and has an annual production
capacity of approximately 450,000 tons. All ovens have a capacity of
approximately eleven to twelve tons of coal per charge. One hundred of the
ovens were built in 1979 and 38 in 1970.
 
  Due to the advanced ages of the coke oven batteries, ongoing environmental
compliance issues and significant capital expenditure requirements, all of
which have combined to reduce productive capacity and increase per unit costs,
the Company's Board of Directors has authorized the Company to close the
Woodward Coke Facility in early 1998. This will result in a charge to earnings
in the fourth quarter of 1997 of approximately $38.5 million, $9.4 million of
which will be cash charges primarily for dismantling and severance costs.
 
  Sales and gross profit at the Woodward Coke Facility for the twelve months
ended September 30, 1997 amounted to $58.1 million and ($6.1) million,
respectively. Capital expenditures and depreciation for the twelve months
ended September 30, 1997 amounted to $3.4 million and $4.4 million,
respectively.
 
  Koppers has made capital expenditures of approximately $25 million to
modernize the Monessen Facility since its purchase in 1995 for $5.0 million.
The Monessen Facility was restarted in late 1995 and reached full production
in April 1996. The plant consists of two batteries with a total of 56 ovens
and has a total capacity of approximately 350,000 tons of coke per year. All
of the ovens were rebuilt in 1980 and 1981, which, together with recent
improvements, makes the Monessen Facility one of the most modern coking
facilities in the United States. The Monessen Facility is self-sufficient in
all its energy needs other than electricity. The Monessen Facility qualifies
for a tax credit based on its production of coke as a non-conventional fuel
and the sale thereof to unrelated third parties. The tax credit generated per
ton of coke is tied to a per-barrel of oil equivalent
 
                                      55
<PAGE>
 
determined on a BTU basis and adjusted annually for inflation. In 1996, the
approximate value of this tax credit per ton of coke was $26.00. The credit is
available through December 31, 2002 and provided a tax benefit to Koppers of
approximately $7.0 million in 1996 and could provide up to $10.2 million per
year thereafter, unadjusted for inflation and assuming the availability of
taxable income and full production at the Monessen Facility. The Company may
monetize some or all of these tax credits. The spot market price for furnace
coke at September 30, 1997 was $107.00 per ton.
 
  Koppers has a contract with LTV covering production at the Monessen
Facility. The contract is a seven-year contract through 2002 and is for
240,000 tons per year, plus or minus 10% at LTV's option, at prices subject to
periodic adjustments. In 1998, the Company expects LTV to take close to 100%
of the Monessen Facility's production capacity.
 
  Due to unanticipated disruptions in United States coke consumption during
1996, along with the increasing availability of lower-priced imported coke,
the current market for coke remains relatively soft, and management believes
that currently there are significant excess inventories of coke in the United
States. In the future, the Company anticipates that additional domestic coking
facilities, including portions of its own facilities, may be idled due to the
costs associated with more stringent environmental compliance standards.
 
KOPPERS AUSTRALIA
 
  Koppers Australia is a wholly owned subsidiary of the Company and is
Australia's largest manufacturer of carbon pitch, wood preservatives and
treated wood products, and markets these products, as well as carbon black, in
Australia, New Zealand and other Pacific Rim nations. Koppers Australia is the
only coal tar distiller in Australia, providing it with a significant
competitive advantage in serving the Australian aluminum smelting industry.
Products and services provided by Koppers Australia's coal tar division are
similar to those provided by the Company's Carbon Materials & Chemicals
division, with the exception that Koppers Australia does not have PAA
production capabilities (see "Business--Carbon Materials & Chemicals").
 
  Operations in coal tar processing, chemically treated wood products, and
carbon black together accounted for 36%, 20% and 21% of Koppers Australia's
net sales respectively, in 1996. Koppers Australia also has a 51% interest in
a wood preservative chemicals company, Koppers-Hickson, which accounts for the
remaining 23% of net sales. Koppers Australia has operations in seven
countries, enjoys sizable market shares in each of its businesses and is well-
positioned to take advantage of anticipated growth in the aluminum industries
in Australia, China and Southeast Asia. Koppers Australia has entered into a
marketing agreement with a carbon pitch producer located in the People's
Republic of China to export carbon pitch from China to world markets. The wood
preservation operations of Koppers Australia are generally pole-related and
are similar to those of the Company's Railroad & Utility Products division.
Koppers Australia is the Australian pole market leader, with an estimated 50%
market share.
 
  In 1995, Koppers Australia purchased the remaining 49% of Continental Carbon
Australia Pty. Ltd., a major Australian carbon black producer, making it a
wholly-owned entity and thus allowing Koppers Australia to take full advantage
of significant growth potential in the Asian carbon black market. Koppers-
Hickson has exclusive rights to marketing, production and distribution of wood
preservatives (primarily copper chrome arsenate) developed by Hickson
International PLC throughout the Australian, South Pacific and East Asian
regions.

EQUITY INVESTMENTS AND RELATED PARTIES
 
 Tarconord
 
  Tarconord, located in Nyborg, Denmark, produces and markets carbon pitch,
naphthalene and related products for the European and Middle Eastern markets.
The Company's 50% partner in Tarconord is Tarco A/S, a road paving and
industrial piping company also located in Denmark. Tarconord's strategy is to
grow through acquisitions as opportunities arise, expand access to secure
long-term coal tar supplies, and gain additional market share.
 
  Tarconord markets its primary product, carbon pitch, to aluminum producers
in Norway, the Netherlands, the states of the former Soviet Union and northern
Germany. Coal tar supplies are primarily purchased from steel producers in
Scandinavia, Poland, the states of the former Soviet Union and Germany.
Tarconord has a strategic location with respect to its largest customer
country, Norway, where liquid pitch shipments move directly by ship from
Tarconord's tar distillation facility at Nyborg to Norwegian smelters located
at deep water sites.
 
  Tarconord helps to position the Company as not only one of the two largest
carbon pitch suppliers in the world, but also as the only such supplier
operating on four continents. Management believes that this global presence
represents a significant competitive advantage in serving multinational and
domestic aluminum manufacturers.
 
  The Company and Tarconord form what has informally and collectively come to
be known as the "Koppers Group" in the world-wide business of tar distillation
and in the production of carbon pitch and accompanying by-products. The
Koppers Group meets regularly and cooperates actively in the sharing of
technology and operating experience, reviewing research and development
projects, sourcing raw materials and determining marketing strategy. The
Company believes that, together with Tarconord, it has a 21% world market
share in carbon pitch, excluding the People's Republic of China and the states
of the former Soviet Union and Eastern Europe (for which data is not
available).
 
  On August 2, 1996, Tarconord acquired 100% of the capital stock of Bitmac, a
United Kingdom company engaged in tar distillation which has had long-term
access to the coal tar generated by British Steel Corporation. Bitmac operates
four plants in the United Kingdom and its sales for its fiscal year ended
March 31, 1996 were approximately $60 million. The Company believes that this
acquisition will more than double Tarconord's capacity and sales and
strengthen its strategic position as a supplier to European aluminum smelters.
 
 Domestic Joint Venture: KSA
 
  KSA Limited Partnership ("KSA"), located in Portsmouth, Ohio, produces
concrete crossties, a complementary product to the Company's treated wood
crosstie business.
 
                                      57
<PAGE>
 
  Other interests are held by Sherman International Corp. (24%), Abetong
America, Inc. (24%) and Sherman Abetong, Inc. (2%). KSA was formed to
construct, own and operate a concrete railroad crosstie manufacturing facility
located in Portsmouth, Ohio. KSA's major customer is CSX, which has a contract
with the joint venture for 1.0 million concrete ties, approximately 0.75
million of which have been supplied since the start-up of operations in 1992.
It has also expanded its product offerings to include concrete turnouts, used
in rail traffic switching, and used crosstie rehabilitation.
 
  The following table presents total sales, equity in earnings and dividends
received with respect to each of the Company's joint ventures for fiscal years

RESEARCH AND DEVELOPMENT
 
  As of September 30, 1997, the Company had ten full-time employees engaged in
research and development and technical service activities. The Company's
research efforts are directed toward further development and utilization of
products and technology regarding products developed from coal tar and
technical service efforts to promote further use of creosote. The Company
believes the research and technical efforts currently expended in these areas
are adequate to maintain a leadership position in the technology related to
these products. Expenditures for research and development for fiscal 1994,
1995 and 1996 were $0.9 million, $0.9 million and $1.0 million, respectively.
 
TECHNOLOGY AND LICENSING
 
  In 1988, Koppers acquired certain assets from Old Koppers 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 the Company, as it represents longstanding,
high-quality products. Included in the patents that were acquired by Koppers
were patents for refuse burners, pitch quality controls (both in tar plants
and aluminum plants), wood preservatives and additives, and tar refining.
 
ENVIRONMENTAL MATTERS
 
  Like companies involved in similar environmentally sensitive businesses, the
Company's operations and properties are subject to extensive Environmental
Laws. The Clean Air Act and Clean Water Act, each as amended, impose stringent
standards on air emissions and water discharges, respectively. Under RCRA, a
facility that treats, stores or disposes of hazardous waste on-site may be
liable for corrective action costs, and a facility that holds a RCRA permit
may have to incur costs relating to the closure of certain "hazardous" or
"solid" waste management units. Under CERCLA and similar state laws, an owner
or operator of property at which
 
                                      58
<PAGE>
 
releases of hazardous substances have occurred may be liable for investigation
and remediation of any resulting contamination and related natural resource
damages. In addition, under CERCLA, the generator of hazardous substances may
be strictly, and jointly and severally liable for any required investigation
or remediation at third-party disposal sites and related natural resource
damages. The Environmental Laws are subject to frequent amendment. The
sanction for failure to comply with such Environmental Laws can include
significant civil penalties, criminal penalties, injunctive relief and denial
or loss of, or imposition of significant restrictions on, environmental
permits. In addition, the Company could be subject to suit by third parties in
connection with violations of or liability under Environmental Laws.
 
  Jefferson County issued a notice of violation in March 1996 in connection
with various alleged violations of Jefferson County's air pollution control
regulations for emissions from coke oven batteries at Koppers' Woodward Coke
Facility during the period May 26, 1992 through March 1, 1996. On February 14,
1997, the US-EPA issued a notice of violation covering the same issues as were
raised in the Jefferson County notice of violation. Thereafter, Koppers
discovered that certain benzene abatement equipment at the its Woodward Coke
Facility had not been operational for several months. Following a preliminary
investigation, Koppers also discovered that certain environmental reports and
records contained incomplete and inaccurate information and that certain
environmental reports and certifications were not filed when required. Koppers
has notified Jefferson County, the State of Alabama and the US-EPA of these
irregularities, and the environmental reporting status of the Woodward Coke
Facility has been brought up to date by Koppers. Counsel and independent
investigators have been retained to conduct a complete and thorough
investigation. While the benzene abatement equipment has been returned to
service, Koppers could be subject to significant liability in connection with
these matters, including civil and criminal penalties and the risk of third-
party lawsuits. Koppers and Jefferson County have negotiated a settlement
agreement, pursuant to which Koppers might be required to install monitoring
and control equipment and institute operational changes. In addition, Koppers
has permanently shut down Batteries 4A, 4B and 5 at the Woodward Coke
Facility. The settlement agreement includes both the original Jefferson County
notice of violation and the self-reported benzene abatement violations. The
settlement agreement, in addition to the items listed above, also required
Koppers to pay a civil penalty in the amount of $450,000 to Jefferson County,
which sum has been paid. There can be no assurance that the settlement with
Jefferson County will deter the US-EPA from pursuing its notice of violation
and that the US-EPA will not seek additional actions or penalties that could
have a material adverse effect on the business, financial condition, cash flow
and results of operations of the Company.
 
  During the investigation of the Woodward Coke Facility described above, it
was also discovered that certain environmental records and reports relating to
discharges of treated process water and treated storm water contained
incomplete and inaccurate information. Corrected reports have been submitted
to the State of Alabama and the US-EPA. While no notice of violation has been
issued in conjunction with this issue, it is believed likely that a notice of
violation will be issued and substantial penalties may be sought by the State
of Alabama or the US-EPA.
 
  Koppers was served with a notice of violation from Pa-DEP, which alleged
Koppers was not in compliance with a plan approval issued by Pa-DEP for the
Monessen Facility. The notice alleges that the Monessen Facility is emitting
more nitrogen oxides than is allowed by the plan approval. Koppers also
received a notice of violation in connection with a failure to conduct timely
emission testing on the boilers at the Monessen Facility. Koppers has
installed additional equipment and modified existing equipment to improve the
quality of boiler emissions. Resolution of these matters could have a material
adverse effect on the business, financial condition, cash flow and results of
operations of the Company. Koppers has submitted an amended plan approval
application to Pa-DEP that provides for limitations on the operation of the
two boilers at the Monessen Facility. Pa-DEP is currently reviewing this
application. As a result of the failure to meet the original nitrogen oxide
emission limitations, it is expected that Pa-DEP will propose a civil penalty
in an amount of approximately $100,000. However, there can be no assurance
that a higher penalty will not be sought.
 
  On June 12, 1996, Pa-DEP issued a notice of violation in connection with an
alleged noncompliance with the terms of a consent agreement between Koppers
and Pa-DEP regarding liability for environmental conditions
 
                                      59
<PAGE>
 
existing at the time Koppers purchased the Monessen Facility ("Consent
Agreement"). The notice of violation alleged that Koppers had not implemented
the corrective actions required under the Consent Agreement in a timely
fashion. Pa-DEP has calculated that a stipulated penalty in the amount of
$261,000 may be requested under the Consent Agreement for the alleged untimely
actions. Koppers has completed the implementation of the corrective actions at
issue and is in the process of conducting settlement negotiations with Pa-DEP
to agree upon the amount of the stipulated penalty to be assessed in
connection with this matter.
 
  In June 1997, during a routine environmental compliance audit of the
Logansport Wood Treating Facility, it was discovered that certain records and
reports relating to discharges of treated process water contained incomplete
and inaccurate information. Corrected reports have been submitted to the local
municipality, the State of Louisiana and the US-EPA. While no notice of
violation has been issued in conjunction with this issue, it is likely that a
notice of violation will be issued and substantial penalties will be sought by
the local municipality, the State of Louisiana or the US-EPA.
 
  For each of the last three fiscal years, the Company's average capital
expenditures and operating expenses for environmental matters, including
depreciation, amounted to approximately $7.0 million and $16.0 million,
respectively. The Company believes that environmental operating costs will not
change materially from those incurred during the past three years. The Company
currently estimates that capital expenditures in connection with matters
relating to environmental control will be approximately $3.8 million and $6.9
million for 1997 and 1998, respectively. Because Environmental Laws have
historically become increasingly more stringent, costs and expenses relating
to environmental control and compliance may increase in the future. Also,
Koppers may have to incur additional capital expenditures and compliance costs
(which it is unable to estimate at this time) in connection with the
resolution of the aforementioned notices of violations. As such, there can be
no assurance that costs of compliance with existing and future Environmental
Laws will not exceed current estimates and will not have a material adverse
effect on the business, financial condition, cash flow and results of
operations of the Company.
 
  Under the terms of the Asset Purchase Agreement between Koppers and Old
Koppers (now known as Beazer East, Inc.) at the formation of Koppers in 1988,
Beazer East assumed the liability for and indemnified Koppers against (among
other things) cleanup liabilities for contamination occurring prior to the
purchase date at sites acquired from Beazer East, and third-party claims
arising from such contamination under the Indemnity. Beazer East's performance
of the Indemnity is unconditionally guaranteed by Beazer Limited under the
Beazer Guarantee. The obligations of Beazer Limited under the Beazer Guarantee
may be enforced directly against Beazer Limited without notice of default to
Beazer East and without making any demand on, obtaining any judgment or order
or commencing any legal proceeding against, or taking any other action against
Beazer East. However, if such indemnification was not available for any
reason, including the inability of Beazer East and/or Beazer Limited to make
such indemnification payments, and if Koppers were required to pay such costs,
it could have a material adverse effect on the business, financial condition,
cash flow and results of operations of the Company. Furthermore, if Koppers
were required to record a contingent liability in respect of environmental
matters covered by the Indemnity on its balance sheets, the result could be
that Koppers would have significant negative net worth.
 
  Five of the sites owned and/or operated by Koppers are listed on the
National Priorities List ("NPL") promulgated under CERCLA. These sites are the
Feather River Wood Treating Facility, Gainesville Wood Treating Facility,
Galesburg Wood Treating Facility, Florence Wood Treating Facility, and
Follansbee Tar Facility. In addition, many of Koppers' sites are or have been
operated under RCRA permits, and RCRA remedial and closure activities are
being conducted on several such sites. Currently, at the properties acquired
from Beazer East (which include all of the NPL sites and all but one of the
RCRA-permitted sites), substantially all investigative, cleanup and closure
activities are being conducted and paid for by Beazer East pursuant to the
terms of the Indemnity. The Indemnity provides that, with certain limited
exceptions, Beazer East will be responsible for and will indemnify Koppers
against any liability, damage, loss, cost, expense and any related fine or
penalty, including liabilities for personal injury to employees resulting from
exposure to toxic or hazardous substances, arising under any federal, state or
local Environmental Law in connection with any

condition or activity at the sites purchased or leased in connection with the
acquisition from Beazer East existing on or prior to the Asset Closing,
provided that, within twelve years after the Asset Closing (December 29, 2000)
Beazer East either receives a claim asserted by Koppers or a third party or
receives specific and particularized notice of a condition or activity that
may give rise to a claim and such a claim is at any time actually brought.
However, claims related to hazardous substances that were both generated at
facilities owned or operated prior to the Asset Closing and disposed of at
third-party locations before the date of the Asset Closing do not have to be
asserted or identified before the twelfth anniversary. Also, Beazer East
indemnifies Koppers for ninety percent (90%) of claims in excess of $100,000
in any year that are related to disposal of contaminated soil generated as a
result of a voluntary decision by Koppers. In regard to personal injury
environmental claims asserted by an employee alleging exposure to toxic
substances in the workplace, such claims are allocated between Beazer East and
Koppers according to how many months the employee making the claim worked for
each entity.
 
  Costs and liabilities associated with investigative, cleanup and closure
activities at the NPL sites and RCRA-permitted facilities acquired from Beazer
East are expected to be significant. While Beazer East has retained and
accepted responsibility for investigative, cleanup and closure activities
relating to pre-Asset Closing contamination at such properties (including
being the signatory on several consent agreements relating to such sites) and
has paid, to date, for substantially all such investigative, remedial and
closure costs, the government has the right under applicable Environmental
Laws to seek relief directly from Koppers for any and all such pre-Asset
Closing obligations and liabilities at or on sites owned or operated by
Koppers. Although Beazer East and Beazer Limited have performed their
respective obligations since 1989, there can be no assurances that Beazer East
and Beazer Limited will continue to meet their obligations under the Indemnity
and the Beazer Guarantee, respectively. Since 1991, Beazer East and Beazer
Limited have been wholly-owned indirect subsidiaries of Hanson PLC. Hanson PLC
recently reorganized by spinning-off its chemicals, tobacco and energy
subsidiaries. However, Koppers has not received information indicating that
this spin-off will adversely affect the ability of Beazer East and Beazer
Limited to meet their obligations under the Indemnity and the Beazer
Guarantee, respectively.
 
  Beazer East is actively fulfilling its obligations to conduct investigative,
cleanup and closure programs at the properties which Koppers acquired from
Beazer East in accordance with the requirements of regulatory authorities. The
Indemnity is not applicable to sites acquired since the formation of Koppers,
for which separate indemnifications have been negotiated where appropriate.
 
  Beazer East and Beazer Limited are indirect subsidiaries of Hanson PLC. The
largest and smallest group in which the result of these companies are
consolidated is that headed by Hanson PLC. Beazer East is an operating company
which had revenues of approximately $600 million for each of the last three
fiscal years ended September 28, 1996 and had total assets of $1.7 billion as
of September 28, 1996. The Beazer East unaudited consolidated balance sheet at
September 28, 1996 reflects negative net worth of $64 million (including an
intercompany liability of $1.4 billion). This negative net worth is in large
measure the result of the adoption of SFAS 121, which resulted in pre-tax
charges for asset write-downs of $4.4 billion during fiscal year 1996.
Furthermore, Beazer East had a negative cash flow from operations in the
fiscal year ended September 28, 1996 and required funding from other Hanson
subsidiaries to meet its obligations. According to the Directors' Report and
draft accounts for the year ended September 30, 1996, Beazer Limited is a
holding company. While the unaudited balance sheet of September 30, 1996
expects to show a negative shareholder funds balance of (Pounds)10.4mn, the
accounts are prepared under the going concern concept because a fellow
subsidiary undertaking provides financial support to enable Beazer Limited to
meet its liabilities as they fall due. The Company has been informed that
Beazer East and Beazer Limited will remain wholly-owned indirect subsidiaries
of Hanson PLC. Management believes that Beazer East and Beazer Limited will
continue to fulfill their obligations as they have for the last eight years.
 
  In the event that Beazer East and Beazer Limited do not continue to fulfill
their commitments under the Indemnity and the Beazer Guarantee, Koppers may be
required to pay costs covered by the Indemnity.

Koppers has been informed by Beazer East that for the last three years,
amounts paid by Beazer East under the Indemnity have averaged approximately
$13.0 million per year. The requirement to pay such costs without
reimbursement would have a material adverse effect on the business, financial
condition, cash flow and results of operations of the Company. Furthermore, if
Koppers were required to record a contingent liability regarding environmental
matters covered by the Indemnity on its balance sheets, the result could be
that Koppers would have significant negative net worth.
 
  In addition, Beazer East has defended and is presently defending certain
toxic tort actions arising from the pre-Asset Closing operation of assets
which the Company acquired from Beazer East. These tort actions were not
assumed by Koppers under the Asset Purchase Agreement and are within the scope
of the Indemnity.
 
  As a result of a lawsuit among CSX, Beazer East and the Company, CSX has
assumed Beazer East's obligations under the Indemnity in connection with
Koppers' facility located in Green Spring, West Virginia. There can be no
assurance that CSX will perform its obligations and if Koppers were required
to pay such costs, it could have a material adverse effect on the business,
financial condition, cash flow and results of operations of the Company.
 
  The Indemnity does not afford Koppers indemnification against environmental
costs and liabilities relating to activities or conditions occurring or
arising after the Asset Closing, nor does the Indemnity cover liabilities
arising in connection with post-Asset Closing acquisitions.
 
  In the summer of 1997, Koppers evaluated the environmental liabilities
related to the manufacturing sites associated with the Asset Closing. The
evaluation was based on a report prepared by an independent consultant, which
utilized site-specific public information to the extent available, as
supplemented by (among other things) its technical knowledge and expertise,
published resources regarding costing of remediation techniques and specified
technical cost and regulatory assumptions. The evaluation and report estimated
that approximately $111.1 million would be expended at these sites for
environmental remediation during the period of 1998 to 2042. Koppers estimates
that approximately $92.9 million of this amount is covered under the
Indemnity, that it is responsible for $135,000, and that identified third
parties are responsible for the remaining $18.1 million. There can be no
assurance, however, that the actual liabilities associated with the
investigation, cleanup and closure of these sites will not exceed this
estimate. The factors that could affect the continuing validity of the
estimate include: new information about the contamination at the sites that is
contrary to previous assumptions, new interpretations of existing
Environmental Laws, new and more stringent Environmental Laws, and more
vigorous enforcement policies of regulatory authorities. Further, in the event
that Beazer East does not fulfill it commitments under the Indemnity or the
identified third parties do not fulfill their commitments, Koppers may be
required to pay costs that would have a material adverse effect on the
business, financial condition, cash flow and results of operation of the
Company.
 
  Koppers is aware of environmental contamination at the Monessen Facility,
which was purchased by Koppers after the Asset Closing (which site was not
previously owned by Beazer East and is thus not subject to the Indemnity).
Koppers has entered into the Monessen Consent Order with Pa-DEP in connection
with this site pursuant to which Koppers' liabilities for environmental
cleanup have been capped at $550,000 for environmental problems which have
been identified pursuant to the Monessen Consent Order.
 
  Koppers purchased a wood treating facility located in Somerville, Texas from
Atchison, Topeka & Santa Fe Railway Company ("Santa Fe") in March 1995. At the
time of the purchase there were several existing environmental issues at the
facility. Santa Fe retained responsibility for remediating and monitoring all
closed solid waste units and surface impoundments at the facility that were in
existence at the time of the sale. Santa Fe indemnified Koppers for all
violations of Environmental Laws or releases of hazardous substances or
petroleum products that occurred before the sale. In addition, for the first
twelve years following the sale, Santa Fe is obligated to indemnify Koppers
for costs that exceed a specified annual cap ($50,000) when such costs arise
from a construction project that Koppers voluntarily initiates and also arise
from complying with Environmental Laws governing containment, disposal or
monitoring of hazardous substances at the site.

  Koppers purchased a tar refinery located in Clairton, PA from Aristech in
April 1996. This tar refinery is located within the boundaries of a coke
facility owned and operated by U.S. Steel Group. U.S. Steel Group had sold the
tar refinery to Aristech in 1986. At the time of the purchase there were
several existing environmental issues at the tar refinery. When USX sold the
tar refinery to Aristech, it provided Aristech with a broad indemnity for
environmental contamination that predated the 1986 sale of the tar refinery to
Aristech. When Koppers purchased the tar refinery from Aristech, it assumed
Aristech's obligations and gained Aristech's protections under the USX
indemnity agreement. The principal obligation is that Koppers must pay for ten
percent (10%) of the environmental remediation costs incurred by USX in
implementing a consent decree concerning the tar refinery and USX's
surrounding coke facility, up to a maximum combined payment by both Koppers
and Aristech of $500,000. Prior to Koppers' purchase of the tar refinery,
Aristech had made payments of approximately $175,000 under the USX indemnity
agreement. To date, Koppers has not made any payments under this indemnity
provision. As part of the agreement with Aristech, Koppers agreed to indemnify
Aristech for environmental claims arising from operations at the tar refinery.
However, the requirement for Koppers to indemnity Aristech has several
exceptions, including but not limited to: claims for which USX will provide
indemnification, personal injury claims arising from a pre-sale chemical
release, and any incident listed on a schedule to the asset purchase
agreement.
 
  At the Clairton facility, the Somerville facility and the Monessen Facility
(all of which Koppers acquired subsequent to the acquisition of the Beazer
East properties), remedial actions are being performed in accordance with
applicable regulations and all indemnification obligations are being honored
at the Clairton and Somerville facilities. The Company believes that the
sellers (or their predecessors) at both of these sites will conduct and
finance most investigative and cleanup activities directly. Although the
Company is not aware of any reason why such indemnification obligations will
not be performed, if Koppers were required to pay costs associated with
environmental contamination at these two sites, it could have a material
adverse effect on the business, financial condition, cash flow and results of
operations of the Company. The Monessen Facility was purchased pursuant to a
bankruptcy sale. Although an environmental indemnification was provided by the
seller of that facility to Koppers, Koppers does not expect that such
indemnification obligations will be honored. If contamination at the Monessen
Facility should be discovered which has not been identified pursuant to the
Monessen Consent Order, or if the US-EPA should require cleanup above the
$550,000 "cap" contained in the Monessen Consent Order, the costs associated
with such events could have a material adverse effect on Koppers' business,
financial position, cash flow and results of operations.
 
  Koppers has made other asset acquisitions that involved purchase of real
property. While environmental indemnifications were obtained as part of the
transactions, the limited financial resources of the selling parties makes
fulfillment of these indemnifications unlikely. Material pre-purchase
environmental conditions identified during the due diligence leading up to
these acquisitions were addressed either before the purchase or immediately
afterwards.
 
  From time to time, Koppers is served with notices of violation and requests
for information relating to environmental compliance matters at the various
facilities it owns and operates. In November 1996, Koppers received an
information request from US-EPA in regard to water discharges from its
facilities. Subsequent to this initial request, Koppers has received two
additional information requests from US-EPA. The initial request and the first
supplemental request have been answered. The second supplemental request is in
the process of being answered. While the US-EPA has not issued a notice of
violation in connection with these requests, there can be no assurance that
civil penalties or the requirement to expend capital resources will not arise.
 
  In September 1996, Koppers was served with a notice of violation from the
Illinois Environmental Protection Agency ("IEPA") relating to 16 releases of
hazardous materials which occurred at or from its facility located in
Stickney, Illinois between January 24, 1990 and May 3, 1996. Koppers has
entered into negotiations with the IEPA to investigate four of the releases
which had the potential to cause groundwater or off-site contamination.
Although Koppers believes that all such releases were remediated when they
occurred, there can be no assurances that the IEPA will not require additional
action in connection with this matter.
 
 
                                      63
<PAGE>
 
  In addition to the environmental issues discussed above, Koppers has
received or expects to receive notices of violations and requests for
information at its Monessen Facility and the Follansbee, Gainesville and
Stickney facilities that relate to matters which Koppers does not believe will
have a material impact on the business, financial condition, cash flow, and
results of operation of the Company.
 
  On occasion, Koppers Australia has been served with notices relating to
environmental compliance issues arising in connection with its operations.
Koppers Australia was served with a notice by the Tasmanian Department of
Environment and Land Management ("DELM") which alleged that the Longford,
Tasmania facility was not in compliance with certain water discharge
requirements. Koppers Australia is currently in negotiations with the DELM
with respect to this issue. In addition, historic operations conducted at the
Koppers Australia facilities have resulted in identified and potential soil
and groundwater contamination of varying degrees. The Trentham, Victoria
facility is listed on the Victorian Register of Contaminated Sites. The
Rockhampton and Takura, Queensland facilities are listed on the Queensland
Register of Contaminated Sites as "probable sites". In addition, Koppers
Australia has identified various levels of groundwater contamination at the
Mayfield, New South Wales and Bunbury, Western Australia facilities. Although
the relevant regulatory authorities have not required the investigation or
remediation of these or other Koppers Australia facilities to date, these
authorities may require such work if Koppers Australia does not undertake such
activities itself. Costs associated with these activities may be material and
there can be no assurance that such costs will not have a material adverse
effect on the business, financial condition, cash flow and results of
operations of the Company.
 
EMPLOYEES AND EMPLOYEE RELATIONS
 
  As of August 31, 1997, the Company employed 601 salaried employees and 1,643
hourly employees. Listed below is a breakdown of employees by business

  Of the Company's 2,244 employees, approximately 1,400 are represented by 17
different unions and covered under 29 separate labor contracts. The United
Steelworkers of America, covering workers at six facilities, accounts for the
largest membership with more than 500 employees. Another significant
affiliation is the Oil, Chemical, and Atomic Workers Union, with approximately
300 employees at four facilities. Labor negotiations are conducted on a plant-
by-plant basis and approximately one-fourth of the outstanding contracts are
renegotiated in any one year.
 
  In the last five years, the Company has had three work stoppages due to
strikes at its Follansbee, Somerville and Galesburg facilities. The Follansbee
strike occurred in November 1993 and the Somerville and Galesburg strikes
occurred in March 1996. In each instance, the Company was able to continue
operation of the respective facilities at approximately 85% of capacity and to
reach agreement with each of the unions on terms satisfactory to the Company.
There can be no assurance that the Company would be able to continue operating
facilities in the event of further work stoppages or union disputes in the
future.
 
LEGAL PROCEEDINGS
 
  Jefferson County issued a notice of violation on March 11, 1996 in
connection with various alleged violations of Jefferson County's air pollution
control rules and regulations for emissions from coke oven batteries
 
                                      64
<PAGE>
 
at Koppers' Woodward Coke Facility. On February 14, 1997, the US-EPA sent a
notice of violation to Koppers that covered the same issues identified in the
Jefferson County notice of violation. Koppers has entered into a settlement
agreement with Jefferson County; however, there can be no assurance that the
US-EPA will not seek additional actions or penalties that could have a
material adverse effect on the business, financial condition, cash flow and
results of operations of the Company. See "Business--Environmental Matters."
 
  Koppers was served with a notice of violation from the Pennsylvania
Department of Environmental Protection ("Pa-DEP"), which alleged Koppers was
not in compliance with a plan approval issued by Pa-DEP for the Monessen
Facility. The notice alleges that the Monessen Facility is emitting more
nitrogen oxides than is allowed by the plan approval. Koppers also received a
notice of violation in connection with a failure to conduct timely emission
monitoring testing on the boilers at the facility. Koppers has installed
additional equipment and modified existing equipment to improve the quality of
boiler emissions. Resolution of these matters could have a negative effect on
the business, financial condition, cash flow and results of operations of the
Company. Koppers has submitted an amended plan approval application to Pa-DEP
that provides for limitations on the operation of the two boilers at the
Monessen Facility. Pa-DEP is currently reviewing this application. As a result
of the failure to meet the original nitrogen oxide emission limitations, it is
expected that Pa-DEP will propose a civil penalty in an amount of
approximately $100,000. See "Business--Environmental Matters."
 
  On June 12, 1996, Pa-DEP issued a notice of violation in connection with an
alleged noncompliance with the terms of a Consent Agreement between the
Company and Pa-DEP regarding liability for environmental conditions existing
at the time Koppers purchased the Monessen Facility. The notice of violation
alleged that Koppers had not implemented the corrective actions required under
the Consent Agreement in a timely fashion. Pa-DEP has calculated that a
stipulated penalty in the amount of $261,000 may be requested under the
Consent Agreement for the alleged untimely actions. Koppers has completed the
implementation of the corrective actions at issue and is in the process of
conducting settlement negotiations with Pa-DEP to agree upon the amount of the
stipulated penalty to be assessed in connection with this matter. See
"Business--Environmental Matters."
 
  The Company is involved in various other proceedings relating to
environmental laws and regulations. See "Business--Environmental Matters."
 
  The Company is involved in various other proceedings incidental to the
ordinary conduct of its business. The Company believes that none of these
other proceedings will have a material adverse effect on the business,
financial condition, cash flow and results of operations of the Company.
 
PROPERTIES
 
  The principal fixed assets of the Company consist of its production,
treatment, and storage facilities and its transportation and plant vehicles.
Its numerous production facilities consist of five Carbon Materials &
Chemicals facilities, 15 wood treating facilities, 14 facilities in the South
Pacific and the Woodward Coke and Monessen Facilities. See "--Carbon Materials
& Chemicals," "--Railroad & Utility Products" and "--Coke Products." As of
December 31, 1996, vehicles and equipment represented approximately 40% of the
Company's total assets, as reflected in its consolidated balance sheet. The
following chart sets forth information regarding the Company's facilities:

                     DESCRIPTION OF NEW CREDIT FACILITIES
 
  Koppers has established New Credit Facilities of $275.0 million aggregate
principal amount with Swiss Bank Corporation, Stamford Branch and Mellon Bank,
N.A. The New Credit Facilities will be syndicated among several lenders who
will be parties thereto (collectively, the "Lenders"), with SBC Warburg Dillon
Read Inc. as arranger and syndication agent, Swiss Bank Corporation, Stamford
Branch, as documentation agent, and Mellon Bank, N.A., as administrative agent
(the "Administrative Agent") (the Administrative Agent together with the other
agents, the "Agents"). The following is a summary description of the principal
terms of the New Credit Facilities. The description set forth below does not
purport to be complete and is qualified in its entirety by reference to the
agreements setting forth the principal terms and conditions of the New Credit
Facilities, which are available upon request from Koppers.
 
  Structure. The New Credit Facilities consist of (a) a Term Loan A Facility
in an aggregate principal amount of $70 million, (b) a Term Loan B Facility in
an aggregate principal amount of $65 million and (c) a Revolving Credit
Facility for up to $140 million, including (i) up to $20 million of such
amount being available as a standby or trade letter of credit sub-facility;
(ii) $10 million of such amount being available as a swing-line sub-facility
and (iii) up to $40 million and $20 million of such amount being exclusively
reserved for use in connection with the Australian Term Letter of Credit and
the Australian Revolving Letter of Credit described below, respectively.
 
 
                                      75
<PAGE>
 
  National Australia Bank, Limited provided an Australian dollar ("A$")
denominated term loan to Koppers Australia and certain of its subsidiaries who
are Subsidiary Guarantors in an aggregate principal amount equivalent to US$40
million. As credit support for such term loan, an A$ denominated letter of
credit (the "Australian Term Letter of Credit") was issued under the Revolving
Credit Facility to such Australian lender in the amount of A$59,303,187.55.
Commonwealth Bank of Australia provided an A$ denominated revolving loan
facility for the benefit of Koppers Australia and certain of its subsidiaries
who are Subsidiary Guarantors with availability of up to the equivalent of
US$10 million. As credit support for such Australian revolving facility, an A$
denominated letter of credit (the "Australian Revolving Letter of Credit") was
issued under the Revolving Credit Facility to such Australian lender in the
amount of A$14,825,796.89. To the extent that currency fluctuations cause the
face amount of the Australian Term Letter of Credit or the Australian
Revolving Letter of Credit to exceed on a US$ equivalent basis their
respective subfacility limits, availability will be correspondingly reduced
under the Revolving Credit Facility.
 
  Availability. Loans under the Term Loan A Facility are available in multiple
draws for up to 364 days from the date on which the other transactions were
consummated and all other conditions to closing were met (the "Closing Date")
for use as follows: on the Closing Date, to provide a portion of the proceeds
necessary to consummate the Recapitalization and to pay related fees and
expenses, and after the Closing Date, to repurchase Senior Notes not tendered
in the Tender Offer or to repurchase shares of the Company's common stock
owned by management or the redemption of shares of Common Stock held by APT
Holdings Corporation if consummated after the Closing Date. Loans under the
Term Loan B Facility and the Australian term loan were drawn on the Closing
Date to provide a portion of the proceeds necessary to consummate the
Recapitalization and to pay related fees and expenses. The Revolving Credit
Facility and the Australian revolving facility are available at any time
during the six-year period following the Closing Date subject to the
fulfillment of certain conditions precedent including the absence of a default
under the New Credit Facilities.
 
  Security; Guarantee. The Company's obligations under the New Credit
Facilities are guaranteed by any subsidiary which guarantees indebtedness
represented by the Notes, Koppers Australia, any subsidiary of the Company
which owns Capital Stock of Koppers Australia and each subsequently acquired
or organized significant subsidiary of the Company, subject to certain
exceptions. The New Credit Facilities and the guarantees thereof are secured
by a perfected first priority lien on, and pledge of, all of the capital stock
and intercompany notes of each of the direct and indirect subsidiaries of the
Company on the Closing Date or thereafter created or acquired and a perfected
first priority security interest in all substantial tangible and intangible
assets and proceeds of the foregoing of the Company and the guarantors subject
to certain permitted liens.
 
  Interest; Maturity. Borrowings under the Term Loan A Facility, the Revolving
Credit Facility and the Australian facilities bear interest, payable
quarterly, at a rate per annum equal to: (i) LIBOR (or in the case of the
Australian facilities, the Bank Swap Reference Rate) plus an applicable margin
or (ii) the Administrative Agent's prime rate (the "base rate") plus an
applicable margin. Borrowings under the Term Loan B Facility bear interest,
payable quarterly, at a rate per annum equal to LIBOR plus an applicable
margin. The initial applicable margin is 1.75% per annum for LIBOR loans and
Bank Swap Reference Rate loans, as the case may be, under the Term Loan A
Facility and the Revolving Credit Facility (including the Australian Term
Letter of Credit and the Australian Revolving Letter of Credit), 2.25% per
annum for loans under the Term Loan B Facility and .75% per annum for base
rate loans, which may only be made under the Term Loan A Facility and the
Revolving Credit Facility (other than the Australian Term Letter of Credit and
the Australian Revolving Letter of Credit). The applicable margins may
increase to as high as 2.0% per annum or reduce ultimately to as low as .75%
per annum in the case of LIBOR loans and Bank Swap Reference Rate loans, as
the case may be, under the Term Loan A Facility and the Revolving Credit
Facility (including the Australian Term Letter of Credit and the Australian
Revolving Letter of Credit), increase to as high as 2.5% per annum or reduce
to as low as 1.75% per annum in the case of loans under the Term Loan B
Facility and increase to as high as 1.0% per annum or reduce to as low as 0.0%
per annum in the case of base rate loans, in each case based upon improved
credit measures. The Term Loan A Facility and the Australian term loan will
mature on the date which is six years
 
                                      76
<PAGE>
 
after the Closing Date, and the Term Loan B Facility will mature on the date
which is seven years after the Closing Date. Amounts outstanding under the
Term Loan Facilities will amortize on a semi-annual basis beginning at the end
of the second full fiscal quarter after the Closing Date. Aggregate principal
payments will be $11.0 million, $16.0 million and $21.0 million for the years
1998, 1999 and 2000, respectively, increasing to a maximum of $45.0 million in
2003.
 
  Fees. The Company will be required to pay the lenders, on a quarterly basis,
a commitment fee initially equal to .375% per annum (which may be increased or
reduced based upon credit measures) on the undrawn portion of the Revolving
Credit Facility and a commitment fee initially equal to .375% per annum on the
undrawn portion of the Term Loan A Facility. The Company is also obligated to
pay: (i) a per annum letter of credit fee equal to the applicable margin for
LIBOR based loans on the aggregate amount of outstanding letters of credit,
including the Australian Term Letter of Credit and the Australian Revolving
Letter of Credit; provided the Australian Revolving Letter of Credit fee will
be based on the daily average outstanding amount of loans under the Australian
revolving facility; (ii) a facing fee for the letter of credit issuing bank;
and (iii) agent, arrangement and other similar fees.
 
  Prepayments. The Term Loan Facilities are required to be prepaid with (a)
100% of the net proceeds (including casualty insurance proceeds) of asset
sales and other asset dispositions for proceeds in excess of a certain
threshold to be mutually agreed (subject to customary exceptions for
inventory, used or obsolete equipment, etc. and to an exclusion for a
specified amount of reinvestments of such proceeds in agreed categories of
assets), (b) 100% of the net proceeds of the issuance or incurrence of debt or
of any sale and lease-back for proceeds in excess of a certain threshold to be
mutually agreed, and (c) 50% of the net proceeds from any issuance of equity
securities in any public offering or private placement or from any capital
contribution (other than net proceeds received upon exercise of employee stock
options, the sale of shares pursuant to the Koppers Industries, Inc. Employee
Stock Purchase Plan and the Koppers Industries, Inc. Stock Redemption and
Purchase Plan, or the resale of shares to Management Investors).
 
  Covenants. The New Credit Facilities contain a number of covenants
including, among other things, limitation on liens; limitation on indebtedness
and guarantees; limitation on loans and investments; limitations on dividends
and stock repurchases to specified amounts; limitation on optional payments
and modification of certain indebtedness; limitation on leases; limitation on
fundamental changes; limitation on disposition of assets and stock and

                             DESCRIPTION OF NOTES
 
  The New Notes, like the Old Notes, will be issued pursuant to the Indenture,
dated December 1, 1997, between the Company and PNC Bank, National Association
(the "Trustee"). The terms of the Notes include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act
of 1939 (the "Trust Indenture Act"). The terms of the New Notes are
substantially identical to the Old Notes in all material respects (including
interest rate and maturity), except that (i) the New Notes will not be subject
to the restrictions on transfer (other than with respect to holders that are
broker-dealers, persons who participated in the distribution of the Old Notes
or affiliates) and (ii) the Registration Rights Agreement covenants regarding
registration and the related Liquidated Damages (other than those that have
accrued and were not paid) with respect to Registration Defaults will have
been deemed satisfied. The Notes are subject to all such terms, and holders of
Notes are referred to the Indenture and the Trust Indenture Act for a
statement thereof. The following summaries of certain provisions of the
Indenture do not purport to be complete and are subject to, and are qualified
in their entirety by reference to, all the provisions of the Indenture,
including the definitions of certain terms therein. Wherever particular
Sections or defined terms of the Indenture not otherwise defined herein are
referred to, such Sections or defined terms shall be incorporated herein by
reference. A copy of the form of Indenture will be made available to any
prospective purchaser of the Notes upon request to the Company.
 
GENERAL
 
  The Notes mature on December 1, 2007. The Notes are limited to $175,000,000
in aggregate principal amount. Each Note bears interest at the rate per annum
shown on the front cover of this Prospectus from December 1, 1997, or from the
most recent date to which interest has been paid or provided for, payable
semi-annually (to Holders of record at the close of business on May 15 or
November 15 immediately preceding such interest payment date) on June 1 and
December 1 of each year, commencing June 1, 1998.
 
  The Notes are issued only in fully registered form, without interest
coupons, and in denominations of $1,000 of principal amount and any integral
multiple thereof. No service charge will be made to a Holder for any
registration of transfer, exchange or redemption of Notes, but the Company may
require payment sufficient to cover any transfer tax or other similar
governmental charge payable in connection therewith.
 
RANKING
 
  The Notes are general unsecured obligations of the Company and rank junior
to, and are subordinated in right of payment to, all existing and future
Senior Debt of the Company, pari passu in right of payment with all senior
subordinated Debt of the Company (except as to secured Debt) and senior in
right of payment to all Subordinated Debt of the Company. In addition, the
Notes are effectively subordinated to all secured obligations to the extent of
the assets securing such obligations. At September 30, 1997, on a pro forma
basis after giving effect to the Saratoga Investment and the Recapitalization,
the Company would have had $175,000,000 Senior Debt outstanding, all of which
would have been secured. All Debt incurred under the New Credit Facilities
will be Senior Debt of the Company and will be secured by substantially all of
the assets of the Company.
 
  Except as described in "Change of Control," the Indenture does not contain
any provision that would provide protection to the holders of the Notes
against a sudden and dramatic decline in credit quality resulting from a
takeover, recapitalization or similar restructuring of the Company. If a
Change of Control were to occur, there can be no assurance that the Company
would have adequate funds to repurchase the Notes as required by the Indenture
and/or that the lenders under the New Credit Facilities will permit such
repurchase. See "--Covenants--Change of Control" and "Description of New
Credit Facilities--Events of Default."
 
OPTIONAL REDEMPTION
 
  The Notes are redeemable, at the Company's option, in whole or in part, at
any time on or after December 1, 2002 and prior to maturity, upon not less
than 30 nor more than 60 days' prior notice mailed by first class
 
                                      78

mail to each Holder's last address as it appears in the registry books, at the
following redemption prices (expressed as percentages of the principal amount)
if redeemed during the 12-month period beginning December 1, of the years
indicated:

plus accrued and unpaid interest, if any, to the date of such redemption.
 
  In addition, at any time prior to December 1, 2000, the Company may, at its
option, redeem up to 35% of the aggregate principal amount of Notes with the
net proceeds of one or more issuances of Common Stock (other than Redeemable
Stock) at a redemption price (expressed as a percentage of principal amount)
of 109.875% plus accrued interest, if any, to the date of such redemption;
provided that at least $100,000,000 aggregate principal amount of Notes would
remain outstanding after giving effect to any such redemption.
 
  In the case of any partial redemption, selection of the Notes for redemption
will be made by the Trustee in such manner as it will deem appropriate and
fair; provided, however, that no Note of $1,000 in original principal amount
or less will be redeemed in part.
 
SUBORDINATION OF THE NOTES
 
  The payment of the principal of and interest or liquidated damages on the
Notes is subordinated in right of payment, to the extent and in the manner
provided in the Indenture, to the prior payment in full in cash of all Senior
Debt, which shall include, for all purposes described in this "Subordination
of the Notes" heading, the cash collateralization in full of all outstanding
letters of credit constituting Senior Debt.
 
  Upon any payment or distribution of assets or securities of the Company of
any kind or character, whether in cash, property or securities (excluding any
payment or distribution of Permitted Junior Securities and excluding any
payment (a "Defeasance Trust Payment") from the trust described under
"Defeasance" (a "Defeasance Trust")), upon any dissolution or winding-up or
total liquidation or reorganization of the Company, whether voluntary or
involuntary or in bankruptcy, insolvency, receivership or other proceedings,
all Senior Debt shall first be paid in full in cash before the Holders of the
Notes or the Trustee on behalf of such Holders shall be entitled to receive
any payment by the Company of the principal of or interest or liquidated
damages on the Notes, or any payment by the Company to acquire any of the
Notes for cash, property or securities, or any distribution by the Company
with respect to the Notes of any cash, property or securities (excluding any
payment or distribution of Permitted Junior Securities and excluding any
Defeasance Trust Payment). Before any payment may be made by, or on behalf of,
the Company of the principal of or interest or liquidated damages on the Notes
upon any such dissolution or winding-up or total liquidation or
reorganization, any payment or distribution of assets or securities of the
Company of any kind or character, whether in cash, property or securities
(excluding any payment or distribution of Permitted Junior Securities and
excluding any Defeasance Trust Payment), to which the Holders of the Notes or
the Trustee on their behalf would be entitled, but for the subordination
provisions of the Indenture, shall be made by the Company or by any receiver,
trustee in bankruptcy, liquidation trustee, agent or other Person making such
payment or distribution, directly to the holders of the Senior Debt (pro rata
to such holders on the basis of the respective amounts of Senior Debt held by
such holders) or their representatives or to the trustee or trustees or agent
or agents under any agreement or indenture pursuant to which any of such
Senior Debt may have been issued, as their respective interests may appear, to
the extent necessary to pay all such Senior Debt in full in cash after giving
effect to any prior or concurrent payment, distribution or provision therefor
to or for the holders of such Senior Debt. In the event that, notwithstanding
the foregoing, the Trustee or any holder of Notes receives any payment or
distribution of assets of the Company of any kind, whether in cash, property
or securities, including, without limitation, by way of set-off or otherwise,
in respect
 
                                      79
<PAGE>
 
of the Notes before all Senior Debt of the Company is paid in full in cash,
then such payment or distribution will be held by the recipient in trust for
the benefit of holders of Senior Debt and will be immediately paid on or
delivered to the holders of Senior Debt or their representative or
representatives to the extent necessary to make payment in full in cash of all
Senior Debt remaining unpaid, after giving effect to any concurrent or
distribution, or provision therefor, to or for the holders of Senior Debt.
 
  No direct or indirect payment (excluding any payment or distribution of
Permitted Junior Securities and excluding any Defeasance Trust Payment but
including the establishment of a Defeasance Trust) by or on behalf of the
Company of principal of or interest or liquidated damages on the Notes, or for
or on account of the purchase, redemption or other acquisition of the Notes by
or on behalf of the Company, whether pursuant to the terms of the Notes, upon
acceleration, pursuant to an Offer (as defined herein), a Change of Control
Offer (as defined herein) or otherwise, will be made (including, without
limitation, by way of set-off) if, at the time of such payment, there exists a
default in the payment of all or any portion of the obligations on any
Designated Senior Debt, whether at maturity, on account of mandatory
redemption or prepayment, acceleration or otherwise, and such default shall
not have been cured or waived or the benefits of this sentence waived by or on
behalf of the holders of such Designated Senior Debt. In addition, during the
continuance of any non-payment event of default with respect to any Designated
Senior Debt pursuant to which the maturity thereof may be immediately
accelerated, and upon receipt by the Trustee of written notice (a "Payment
Blockage Notice") from the holder or holders of such Designated Senior Debt or
the trustee or agent acting on behalf of the holders of such Designated Senior
Debt, then, unless and until such event of default has been cured or waived or
has ceased to exist or such Designated Senior Debt has been discharged or
repaid in full in cash or the benefits of these provisions have been waived by
the holders of such Designated Senior Debt, no direct or indirect payment
(excluding any payment or distribution of Permitted Junior Securities and
excluding any Defeasance Trust Payment but including the establishment of the
Defeasance Trust) will be made (including, without limitation, by way of set-
off) by or on behalf of the Company of principal of or interest or liquidated
damages on the Notes, or for or on account of the purchase, redemption or
other acquisition of the Notes by or on behalf of the Company, to such
Holders, during a period (a "Payment Blockage Period") commencing on the date
of receipt of such notice by the Trustee and ending 179 days thereafter.
Notwithstanding anything in the subordination provisions of the Indenture or
the Notes to the contrary, (x) in no event will a Payment Blockage Period
extend beyond 179 days from the date the Payment Blockage Notice in respect
thereof was given, and (y) not more than one Payment Blockage Period may be
commenced with respect to the Notes during any period of 360 consecutive days.
No event of default that existed or was continuing on the date of commencement
of any Payment Blockage Period with respect to the Designated Senior Debt
initiating such Payment Blockage Period (to the extent the holder of
Designated Senior Debt, or trustee or agent, giving notice commencing such
Payment Blockage Period had knowledge of such existing or continuing event of
default) may be, or be made, the basis for the commencement of any other
Payment Blockage Period by the holder or holders of such Designated Senior
Debt or the trustee or agent acting on behalf of such Designated Senior Debt
whether or not within a period of 360 consecutive days, unless such event of
default has been cured or waived for a period of not less than 90 consecutive
days.
 
  The failure to make any payment or distribution for or on account of the
Notes by reason of the provisions of the Indenture described under this
"Subordination of the Notes" heading will not be construed as preventing the
occurrence of any Event of Default in respect of the Notes. See "Events of
Default" below.
 
  By reason of the subordination provisions described above, in the event of
insolvency of the Company, funds which would otherwise be payable to Holders
of the Notes will be paid to the holders of Senior Debt to the extent
necessary to pay the Senior Debt in full in cash, and the Company may be
unable to meet fully its obligations with respect to the Notes.
 
  At the time of issuance of the Old Notes, loans outstanding under the New
Credit Facilities were the only outstanding Senior Debt. Subject to the
restrictions set forth in the Indenture, in the future the Company may issue
additional Senior Debt to refinance existing Debt or for other corporate
purposes.

GUARANTEES OF THE NOTES
 
  The Indenture provides that each of the Subsidiary Guarantors will
unconditionally guarantee on a joint and several, senior subordinated basis
all of the Company's obligations under the Notes, including its obligations to
pay principal and interest with respect to the Notes. The Subsidiary
Guarantors also guaranteed all obligations of the Company under the New Credit
Facilities, and each Subsidiary Guarantor granted a security interest in
substantially all its assets to secure the obligations under the New Credit
Facilities.
 
  The obligations of each Subsidiary Guarantor are limited to the maximum
amount which, after giving effect to all other contingent and fixed
liabilities of such Subsidiary Guarantor and after giving effect to any
collections from or payments made by or on behalf of any other Subsidiary
Guarantor in respect of the obligations of such other Subsidiary Guarantor
under its Subsidiary Guarantee or pursuant to its contribution obligations
under the Indenture, will result in the obligations of such Subsidiary
Guarantor under its Subsidiary Guarantee not constituting a fraudulent
conveyance or fraudulent transfer under Federal or state law. Each Subsidiary
Guarantor that makes a payment or distribution under a Subsidiary Guarantee
shall be entitled to a contribution from each other Subsidiary Guarantor in a
pro rata amount, based on the net assets of each Subsidiary Guarantor
determined in accordance with GAAP. Except as provided in "--Covenants" below,
the Company is not restricted from selling or otherwise disposing of any of
the equity interests of the Subsidiary Guarantors.
 
  The Indenture provides that each of the Company's Subsidiaries formed or
acquired after the date of issuance of the Notes that provides a Guarantee
under the New Credit Facilities will be required to be a Subsidiary Guarantor.
The Company will cause each Subsidiary required to issue a Subsidiary
Guarantee after the date of issuance of the Notes to (i) execute and deliver
to the Trustee a supplemental indenture in form reasonably satisfactory to the
Trustee pursuant to which such Subsidiary shall become a party to the
Indenture and thereby unconditionally guarantee all of the Company's
Obligations under the Notes and the Indenture on the terms set forth therein
and (ii) deliver to the Trustee an opinion of counsel that such supplemental
indenture has been duly authorized, executed and delivered by such Subsidiary
and constitutes a legal, valid, binding and enforceable obligation of such
Subsidiary (which opinion may be subject to customary assumptions and
qualifications). Thereafter, such Subsidiary shall (unless released in
accordance with the terms of this Indenture) be a Subsidiary Guarantor for all
purposes of the Indenture.
 
  The Indenture provides that if the Notes thereunder are defeased in
accordance with the terms of the Indenture, or if, subject to the requirements
of the first paragraph under "Consolidation, Merger and Sale of Assets," all
or substantially all of the assets of any Subsidiary Guarantor or all of the
equity interests of any Subsidiary Guarantor are sold (including by issuance
or otherwise) by the Company in a transaction constituting an Asset
Disposition, and if (x) the Net Cash Proceeds from such Asset Disposition are
used in accordance with the covenant described under "--Covenants--Limitation
on Asset Disposition" or (y) the Company delivers to the Trustee an Officers'
Certificate to the effect that the Net Cash Proceeds from such Asset
Disposition shall be used in accordance with the covenant described under "--
Covenants--Limitation on Asset Disposition" and within the time limits
specified by such covenant, then such Subsidiary Guarantor (in the event of a
sale or other disposition of all of the equity interests of such Subsidiary
Guarantor) or the corporation acquiring such assets (in the event of a sale or
other disposition of all or substantially all of the assets of such Subsidiary
Guarantor) shall be released and discharged of its Subsidiary Guarantee
obligations in respect of the Indenture and the Notes.
 
  The Subsidiary Guarantees are joint and several, general unsecured
obligations of the Subsidiary Guarantors. The respective obligations of each
Subsidiary Guarantor under its Subsidiary Guarantee are subordinated and
junior in right of payment to the prior payment in full of all existing and
future Guarantor Senior Debt of such Subsidiary Guarantor, as the case may be,
to substantially the same extent as the Notes are subordinated to all existing
and future Senior Debt of the Company. No separate financial statements of any
of the Subsidiary Guarantors are presented herein, except for Koppers
Australia, as management believes that such financial statements would not
provide any additional meaningful information.

holder thereof, other than an option given to a holder pursuant to an "asset
sale" or "change of control" covenant which is no more favorable to the
holders of such Debt than the corresponding provisions contained in the
Indenture, and such Debt provides that the Company will not repurchase such

Notes required to be repurchased by the Company pursuant to the corresponding
provisions contained in the Indenture) at any time prior to the final

not otherwise provided for in clauses (i) through (xiii) above, Debt of the
Company in an aggregate outstanding principal amount not to exceed $5,000,000
at any one time outstanding.
 
  Notwithstanding the provisions set forth in the preceding paragraph, the
Company and the Subsidiary Guarantors may Incur Debt, including Acquisition
Debt, if on the Determination Date and after giving effect to the Incurrence
of such Debt and the application of the proceeds therefrom, the Consolidated
Fixed Charge Ratio for the Reference Period immediately preceding the
Determination Date is greater than 2.0 to 1.
 
 Limitation on Guarantees of Debt by Subsidiaries.
 
  The Indenture provides that in the event that any Subsidiary, directly or
indirectly, Guarantees any Debt of the Company under the New Credit Facilities
(the "Other Debt"), the Company will cause such Subsidiary to concurrently
Guarantee the Company's Obligations under the Indenture and the Notes to the
same extent that such Subsidiary Guaranteed the Company's Obligations under
the Other Debt (including waiver of subrogation, if any); provided, however,
that if such Other Debt is (i) Senior Debt, such Subsidiary Guarantee will be
subordinated in right of payment to all Guarantor Senior Debt (which will
include such Guarantee of such Other Debt) pursuant to the subordination
provisions of the Indenture (which subordination will be substantially
identical to the subordination provisions of the Indenture applicable to the
Notes), (ii) Debt which is not Senior Debt or Subordinated Debt, such
Subsidiary Guarantee will be pari passu in right of payment with the Guarantee
of the Other Debt, or (iii) Subordinated Debt, such Subsidiary Guarantee will
be senior in right of payment to
 
                                      93
<PAGE>
 
the Guarantee of the Other Debt (which Guarantee of such Subordinated Debt
will provide that such Guarantee is subordinated to the Subsidiary Guarantee
to the same extent and in the same manner as the Notes are subordinated to
Senior Debt); provided, further, however, that each Subsidiary issuing a
Subsidiary Guarantee will be automatically and unconditionally released and
discharged from its obligations under such Subsidiary Guarantee upon the
release or discharge of the Guarantee of the Other Debt that resulted in the
Company's obligations under the Notes and the Indenture being so Guaranteed.
The Company will cause each Subsidiary required to issue a Subsidiary
Guarantee after the date of issuance of the Notes to make certain deliveries,
and such deliveries will have the effects, described above under "Guarantees
of the Notes."
 
 Limitation on Layering.
 
  The Company shall not, directly or indirectly, Incur any Debt that by its
terms would expressly rank senior in right of payment to the Notes and
expressly rank subordinate in right of payment to any other Debt of the
Company.
 
  The Company shall not permit any Subsidiary Guarantor to, and no Subsidiary
Guarantor shall, directly or indirectly, Incur any Debt that by its terms
would expressly rank senior in right of payment to the Subsidiary Guarantee of
such Subsidiary Guarantor and expressly rank subordinate in right of payment
to any Guarantor Senior Debt of such Subsidiary Guarantor.
 
 Limitations on Restricted Payments.
 
  Under the terms of the Indenture, the Company will not, and will not permit
any of its Subsidiaries to, directly or indirectly, make any Restricted
Payment unless (a) at the time of such Restricted Payment or after giving
effect thereto, no Event of Default, and no event that through the passage of
time or the giving of notice, or both, would become an Event of Default, will
have occurred and be continuing, (b) after giving effect thereto, the Company
could Incur at least $1.00 of Debt pursuant to the provisions described in the
second paragraph under "Limitations on Debt" and (c) after giving effect
thereto, the aggregate amount of all Restricted Payments
made by the Company and its Subsidiaries after the date of issuance of the
Notes will not exceed the sum (without duplication) of: (i) 50% of
Consolidated Net Income of the Company accrued for the period (taken as one
accounting period) commencing with January 1, 1998, and ending with the first
full fiscal quarter ended immediately prior to the date of such calculation;
provided that if Consolidated Net Income for such period is less than zero,
then minus 100% of the amount of such loss; plus (ii) 50% of that portion of
the net after tax cash proceeds from the sale, transfer, carryover, lease or
other disposition of the Monessen Facility that is directly attributable to
the Monessen Section 29 Tax Credits; plus (iii) the aggregate net cash
proceeds received by the Company from the issuance or sale (other than to a
Subsidiary) of its Capital Stock (other than Redeemable Stock) after the date
of issuance of the Notes (including Capital Stock (other than Redeemable
Stock) issued upon conversion of, or in exchange for, securities other than
its Capital Stock), and warrants and other rights to purchase (not including
any such warrants or rights to purchase which are redeemable at the option of
the holder thereof) its Capital Stock (other than Redeemable Stock); plus (iv)
$5,000,000. Notwithstanding the foregoing, the Company may make payment of a
dividend or other distribution on account of its shares of Capital Stock
within 90 days of the declaration thereof if such declaration was permitted
under the provisions described in this paragraph.
 
 Limitations on Asset Disposition.
 
  Under the terms of the Indenture, except for any Asset Disposition permitted
to be made as described in "Consolidation, Merger and Sale of Assets," if the
aggregate fair market value of all Asset Dispositions (as determined in good
faith by the Board of Directors as of the time of each Asset Disposition)
during any consecutive twelve-month period will exceed $5,000,000 the Company
will not make, and will not permit any of its Subsidiaries to make, any Asset
Disposition unless (i) the Company (or the Subsidiary, as the case may be)
receives consideration at the time of each such Asset Disposition at least
equal to the fair market value of the
 
                                      94
<PAGE>
 
shares or assets sold or otherwise disposed of (as determined in good faith by
the Board of Directors if the Asset Disposition involves shares or assets
having a fair market value of more than $10,000,000); (ii) not less than 80%
of the consideration received by the Company (or such Subsidiary, as the case
may be) is in the form of cash (other than in the case of a full or partial
disposition of the Monessen Facility for the purpose of effecting the sale of
all or a portion of the Monessen Section 29 Tax Credits), provided that any
note or other obligation received by the Company (or such Subsidiary, as the
case may be) that is immediately converted into cash will be deemed to be cash
for purposes of clause (ii); and (iii) the Net Cash Proceeds from such Asset
Dispositions are applied, (A) within twelve months of the date of the receipt
of the Net Cash Proceeds, (1) to the reinvestment in the business or
businesses of the Company or any of its Subsidiaries; provided, that this
clause (1) shall not be applicable in the case of Net Cash Proceeds from any
Asset Disposition in the form of a Receivables Transaction or (2) to the
extent such Net Cash Proceeds are not actually applied, or cannot be applied,
in accordance with clause (1), or, if after being so applied there remain Net
Cash Proceeds, to repay Senior Debt or Guarantor Senior Debt (other than the
Notes and Debt owed by the Company to a Subsidiary of the Company or by a
Subsidiary of the Company to the Company or another Subsidiary) (including
interest thereon and fees, expenses and other obligations related thereto) and
in connection with any such payment, any related loan commitment, standby
facility or the like will be reduced in an amount equal to the principal
amount so repaid, and (B) to the extent that such Net Cash Proceeds are not
actually applied in accordance with clause (A), or, if after being so applied
there remain Net Cash Proceeds, to make an Offer to purchase the Notes as
described in the following paragraph. Notwithstanding the foregoing, to the
extent that any or all of the Net Cash Proceeds of any Asset Disposition are
prohibited or delayed by applicable non-United States law from being
repatriated to the United States, the portion of such Net Cash Proceeds so
affected will not be required to be applied as described in this clause (other
than to repay Debt of the Subsidiary making such Asset Disposition as
contemplated by clause (A)) at the time provided above but may be retained by
the applicable Subsidiary for so long, but only so long as the applicable
local law will not permit repatriation to the United States and once such
repatriation of any of such affected Net Cash Proceeds is permitted under the
applicable local law, such repatriation will be immediately effected and such
repatriated Net Cash Proceeds will be applied in the manner described in this
section; provided that to the extent that the Company has determined in good
faith that repatriation of any or all of the Net Cash Proceeds of any such
Asset Disposition would have a material adverse tax cost consequence, the Net
Cash Proceeds so affected may be retained by the applicable Subsidiary for so
long as such material adverse tax cost event would continue.
 
  In the event Net Cash Proceeds are required to be applied to the purchase of
Notes as described in clause (iii) of the preceding paragraph, the Company
will be required to purchase Notes tendered pursuant to a tender offer by the
Company for the Notes (the "Offer") at a purchase price of 100% of the
principal amount of the Notes plus accrued interest to the purchase date in
accordance with the procedures (including prorating in the event of
oversubscription) described in the Indenture. If the aggregate purchase price
of Notes tendered pursuant to the Offer is less than the Net Cash Proceeds
allotted to the purchase of the Notes, the Company may utilize such Net Cash
Proceeds for any purpose otherwise permitted under the Indenture. The Company
will not be required to make an Offer for Notes as described in this section
if the Net Cash Proceeds available therefor are less than $5,000,000 (which
lesser amounts not applied to an offer will be carried forward and cumulated
for each 36 consecutive month period for purposes of determining whether an
Offer is required with respect to the Net Cash Proceeds from any subsequent
Asset Disposition).
 
  Within 30 days after the date on which Net Cash Proceeds that are required
to be applied to an Offer exceed $5,000,000, the Company will be obligated to
deliver to the Trustee and the Trustee will send by first-class mail to each
Holder a written notice stating that: (1) such Holder may elect to have his
Notes purchased by the Company either in whole or in part (subject to
prorating as hereinafter described in the event the Offer is oversubscribed)
in multiples of $1,000 principal amount, at the applicable purchase price; (2)
any Note not tendered or accepted for payment will continue to accrue
interest; (3) any Note accepted for payment pursuant to the Offer will cease
to accrue interest after the purchase date; and (4) Holders will be entitled
to withdraw their election in the manner described in the following paragraph.
The notice will also specify a purchase date not less than 30 days nor more
than 60 days after the date of such notice and will contain information
concerning the
 
                                      95
<PAGE>
 
business of the Company which the Company in good faith believes will enable
such Holders to make an informed decision.
 
  Holders electing to have a Note purchased will be required to surrender the
Note, with an appropriate form duly completed, to the Trustee at the address
specified in the notice at least one Business Day prior to the Purchase Date.
Holders will be entitled to withdraw this election if the Trustee or paying
agent (if any) receives not later than the close of business on the Business
Day prior to the Purchase Date a telegram, telex, facsimile transmission, or
letter setting forth the name of the Holder and a statement that such Holder
is withdrawing his election to have all or a portion of his Notes purchased.
If at the expiration of the Offer Period the aggregate principal amount of
Notes surrendered by Holders exceeds the Offer Amount, the Company will select
the Notes to be purchased on a pro rata basis (with such adjustments as may be
deemed appropriate by the Company so that only Notes in denominations of
$1,000 or integral multiples thereof, will be purchased). Holders whose Notes
are purchased only in part will be issued new Notes equal in principal amount
to the unpurchased portion of the Notes surrendered.
 
  In the event the Company is unable to purchase Notes from Holders in an
Offer because such purchase is prohibited by any provision of applicable law,
the Company need not make an Offer. The Company will then be obligated to use
such Net Cash Proceeds as described in clause (iii) of the first paragraph of
this section.
 
  Whenever Net Cash Proceeds are received by the Company, and prior to the
allocation of such Net Cash Proceeds as described in this section, such Net
Cash Proceeds will be set aside by the Company in a separate account pending
allocation.
 
 Limitations on Dividends and Other Payment Restrictions Affecting
Subsidiaries.
 
  Under the terms of the Indenture, the Company will not, and will not permit
any Subsidiary to, create, assume or otherwise cause or suffer to exist or to
become effective any consensual encumbrance or restriction on the ability of
any Subsidiary to (a) pay dividends or make any other distributions on its
Capital Stock; (b) make payments in respect of any Debt owed to the Company or
any of the Company's Subsidiaries; (c) make loans or advances to the Company
or any of the Company's Subsidiaries; or (d) transfer any of its property to
the Company or any of the Company's Subsidiaries other than (i) encumbrances
and restrictions included (1) in the Indenture or (2) in any agreement in
effect on the date of the Indenture (including, without limitation, the New
Credit Facility) or (3) in any partial or total initial or successive
refinancing, refunding or replacement of any agreement referred to in clause
(2), provided that any encumbrances or restrictions in any such refinancing,
refunding, replacement, amendment, modification or supplement are not
materially less favorable to the Company than those in such agreement in
effect on the date of the Indenture; (ii) customary provisions contained in
agreements with respect to Liens applicable to the assets subject to such
Liens; (iii) encumbrances or restrictions binding upon any Person at the time
such Person becomes a Subsidiary of the Company, provided that such
encumbrances or restrictions were not incurred in anticipation of such Person
becoming a Subsidiary of the Company or (iv) restrictions applicable to a
Receivables Subsidiary arising from a Receivables Transaction. Nothing
described in this section will prevent the Company from Incurring or suffering
to exist any Lien which is permitted as described in "Limitations on Liens."
 
 Limitations on Issuance of Subsidiary Preferred Stock.
 
  Under the terms of the Indenture, the Company will not permit any of its
Subsidiaries to issue any Preferred Stock (other than to the Company or a
Wholly-Owned Subsidiary) or permit any Person (other than the Company or a
Wholly-Owned Subsidiary) to own or hold any interest in any Preferred Stock of
any such Subsidiary unless the Subsidiary would be permitted to Incur Debt as
described in "Limitations on Debt" in an aggregate principal amount equal to
the aggregate liquidation value of such Preferred Stock.
 
 
                                      96
<PAGE>
 
 Limitations on Liens.
 
  The Company will not, and will not cause or permit any Subsidiary to,
directly or indirectly, Incur or suffer to exist any Liens of any kind against
or upon any of their respective properties or assets now owned or hereafter
acquired, or any proceeds therefrom or any income or profits therefrom, to
secure any Debt unless contemporaneously therewith effective provision is
made, in the case of the Company, to secure the Notes and all other amounts
due under the Indenture, and in the case of a Subsidiary which is a Subsidiary
Guarantor, to secure such Subsidiary Guarantor's Subsidiary Guarantee and all
other amounts due under the Indenture, equally and ratably with such Debt (or,
in the event that such Debt is subordinated in right of payment to the Notes
or such Subsidiary Guarantee, prior to such Debt) with a Lien on the same
properties and assets securing such Debt for so long as such Debt is secured
by such Lien, except for (i) Liens securing any Senior Debt or any Guarantor
Senior Debt, (ii) Liens securing Debt of a Subsidiary which is not required to
be a Subsidiary Guarantor and (iii) Permitted Liens.
 
 Limitations on Sale and Leaseback Transactions.
 
  The Company will not and will not permit any Subsidiary to enter into any
Sale and Leaseback Transaction with respect to any assets (whether now owned
or hereafter acquired) unless (i) the net proceeds of the sale or transfer of
the property to be leased are at least equal to the fair market value (as
determined by the Board of Directors of the Company) of such assets (other
than in the case of a Sale and Leaseback Transaction entered into in
connection with an Approved Government Financing) and (ii) the Company could
incur the Attributable Debt in respect of such Sale and Leaseback Transaction
in compliance with the covenant described under "Limitation on Debt."
 
 Transactions with Affiliates.
 
  Neither the Company nor any of its Subsidiaries will directly or indirectly
enter into any transaction (including, without limitation, the sale, purchase
or lease of any assets or properties or the rendering of any services) with
any Affiliate of the Company or direct or indirect holder of 5% or more of any
class of Capital Stock of the Company or any such Affiliate (other than a
Wholly-Owned Subsidiary of the Company) except for transactions made in good
faith the terms of which are fair and reasonable to the Company or such
Subsidiary, as the case may be, and are at least as favorable as the terms
which could be obtained by the Company or such Subsidiary, as the case may be,
in a comparable transaction made on an arm's length basis with Persons who are
not such a holder or Affiliate; provided that any such transaction will be
conclusively deemed to be on terms which are fair and reasonable to the
Company or any of its Subsidiaries and on terms which are at least as
favorable as the terms which could be obtained on an arm's length basis with
Persons who are not such a holder or Affiliate if such transaction is approved
by a majority of the Company's disinterested directors and; provided further
that with respect to any transaction or series of related transactions the
aggregate amount of which is in excess of $10,000,000, in addition to approval
of its board of directors, the Company will obtain a written opinion of an
Independent Financial Advisor stating that the terms of such transaction are
fair to the Company or its Subsidiary, as the case may be, from a financial
point of view. The covenant described in this paragraph will not apply to (a)
the payment of reasonable and customary regular fees to directors of the
Company, (b) any Permitted Payment and any Restricted Payment not otherwise
prohibited by the Indenture or (c) transactions between a Receivables
Subsidiary and any Person as part of a Receivables Transaction, but only to
the extent such transactions are solely in connection with the Receivables
Transaction.

require that the Company repurchase such Holder's Notes at a repurchase price
in cash equal to 101% of the principal amount thereof plus accrued and unpaid
interest, if any, to the date of repurchase, in accordance with the terms
contemplated in the following paragraph (the "Change of Control Offer").
 
 
                                      97
<PAGE>
 
  Within 30 days following any Change of Control, the Company will mail a
notice to each Holder with a copy to the Trustee stating: (1) that a Change of
Control has occurred and that such Holder has the right to require the Company
to repurchase such Holder's Notes at a repurchase price in cash equal to 101%
of the principal amount the plus accrued and unpaid interest, if any, to the
date of repurchase (the "Change of Control Purchase Price"); (2) the

from the date such notice is mailed) (the "Repurchase Date"); (4) that any
Note not tendered will continue to accrue interest; (5) that any Note accepted
for payment pursuant to the Change of Control Offer will cease to accrue
interest after the Repurchase Date, (6) that holders electing to have a Note

have their Notes purchased only in part will be issued new Notes in a

  On the Repurchase Date, the Company will (i) accept for payment Notes or
portions thereof tendered pursuant to the Change of Control Offer, (ii)
deposit with the Trustee money sufficient to pay the purchase price of all
Notes or portions thereof so tendered and (iii) deliver or cause to be
delivered to the Trustee Notes so accepted together with an officers'
certificate stating the Notes or portions thereof tendered to the Company. The

amount equal to the purchase price, and prompt authenticate and mail to such
holders a new Note in a principal amount equal to any unpurchased portion of

Change of Control Offer on or as soon as practicable after the Repurchase
Date.
 
  The Indenture will require that if the New Credit Facilities are in effect,
or any amounts are owing thereunder or in respect thereof, at the time of the
occurrence of a Change of Control, prior to the mailing of the notice to
holders described in the preceding paragraph, but in any event within 20 days
following any Change of Control, the Company covenants to (i) repay in full
all obligations under or in respect of the New Credit Facilities or offer to
repay in full all obligations under or in respect of the New Credit Facilities
and repay the obligations under or in respect of the New Credit Facilities of
each lender who has accepted such offer or (ii) obtain the requisite consent
under the New Credit Facilities to permit the repurchase of the Notes as
described above. The
Company must first comply with the covenant described in the preceding
sentence before it shall be required to purchase Notes in the event of a
Change of Control; provided that the Company's failure to comply with the
covenant described in the preceding sentence constitutes an Event of Default
described in clause (c) under "Events of Default" below if not cured within 30
days after the notice required by such clause. As a result of the foregoing, a
holder of the Notes may not be able to compel the Company to purchase the
Notes unless the Company is able at the time to refinance all of the
obligations under or in respect of the New Credit Facilities or obtain
requisite consents under the New Credit Facilities. Failure by the Company to
make a Change of Control Offer when required by the Indenture constitutes a
default under the Indenture and, if not cured within 30 days after notice,
constitutes an Event of Default.
 
  The Indenture will require that (A) if the Company or any Subsidiary thereof
has issued any outstanding (i) Debt that is subordinated in right of payment
to the Notes or (ii) Preferred Stock, and the Company or such Subsidiary is
required to make a change of control offer or to make a distribution with
respect to such subordinated Debt or Preferred Stock in the event of a change
of control, the Company will not consummate any such offer or distribution
with respect to such subordinated Debt or Preferred Stock until such time as
the Company will have paid the Change of Control Purchase Price in full to the
holders of Notes that have accepted
 
                                      98
<PAGE>
 
the Change of Control Offer and shall otherwise have consummated the Change of
Control Offer made to holders of the Notes and (B) the Company will not issue
Debt that is subordinated in right of payment to the Notes or Preferred Stock
with change of control provisions requiring the payment of such Debt or
Preferred Stock prior to the payment of the Notes in the event of a Change in
Control under the Indenture.
 
  In the event that a Change of Control occurs and the holders of Notes
exercise their right to require the Company to repurchase Notes, if such
repurchase constitutes a "tender offer" for purposes of Rule 14e-1 under the
Exchange Act at that time, the Company will comply with the requirements of
Rule 14e-1 as then in effect with respect to such repurchase.
 
 Reports.
 
  Whether or not required by the rules and regulations of the Securities and
Exchange Commission (the "Commission"), so long as any Notes are outstanding,
the Company will file with the Commission, to the extent such filings are
accepted by the Commission, and will furnish to the holders of Notes all
quarterly and annual reports and other information, documents and reports that
would be required to be filed with the Commission pursuant to Section 13 of
the Exchange Act if the Company were required to file under such section. In
addition, the Company will make such information available to prospective
purchasers of the Notes who request it in writing.
 
EVENTS OF DEFAULT
 
  In case one or more of the following Events of Default (whatever the reason
for such Event of Default and whether it will be voluntary or involuntary or
be effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or
governmental body) will have occurred and be continuing: (a) default in the
payment of any installment of interest upon any of the Notes as and when the
same will become due and payable, and continuance of such default for a period
of 30 days; (b) default in the payment of all or any part of the principal on
any of the Notes as and when the same will become due and payable either at
maturity, upon any redemption, upon mandatory repurchase, by declaration or
otherwise; or (c) failure on the part of the Company duly to observe or
perform any other of the covenants or agreements on the part of the Company in
the Notes or in the Indenture contained for a period of 60 days after the date
on which written notice specifying such failure, stating that such notice is a
"Notice of Default" under the Indenture and demanding that the Company remedy
the same, will have been given by registered or certified mail, return receipt
requested, to the Company by the Trustee, or to the Company and the Trustee by
the holders of at least 25% in aggregate principal amount of the Notes at the
time outstanding; (d) an involuntary case or other proceeding shall be
commenced against the Company or any of its Subsidiaries seeking liquidation,
reorganization or other relief with respect to it or its debts under any
bankruptcy, insolvency or other similar law now or hereafter in effect or
seeking the appointment of a trustee, receiver, liquidator, custodian or other
similar official of it or any substantial part of its property, and such
involuntary case or other proceeding shall remain undismissed and unstayed for
a period of 60 days; or an order for relief shall be entered against the
Company or any of its Subsidiaries under the federal bankruptcy laws as now or
hereafter in effect; (e) the Company or any of its Subsidiaries will commence
a voluntary case under any applicable bankruptcy, insolvency or other similar
law now or hereafter in effect, or consent to the entry of an order for relief
in an involuntary case under any such law, or consent to the appointment or
taking possession by a receiver, liquidator, assignee, custodian, trustee,
sequestrator (or similar official) of the Company or any of its Subsidiaries
or for any substantial part of its property, or make any general assignment
for the benefit of creditors; (f) an event of default, as defined in any
indenture or instrument evidencing or under which the Company or any
Subsidiary has at the date of the Indenture or will hereafter have outstanding
at least $10,000,000 aggregate principal amount of Debt, will have occurred
and be continuing and such Debt will have been accelerated so that the same
will be or become due and payable prior to the date on which the same would
otherwise have become due and payable, and such acceleration will not be
rescinded or annulled within 30 days after such acceleration, provided that if
such event of default under such indenture or instrument will be remedied or
cured by the Company or waived by the
 
                                      99
<PAGE>
 
holders of such indebtedness, then the Event of Default under the Indenture by
reason thereof will be deemed likewise to have been thereupon remedied, cured
or waived without further action upon the part of either the Trustee or any of
the Noteholders; (g) any final judgment or order (not covered by insurance)
for the payment of money in excess of $10,000,000 in the aggregate for all
such final judgments or orders (treating any deductibles, self-insurance or
retention as not so covered) will be rendered against the Company or any
Subsidiary and will not be discharged, and there will be any period of 30
consecutive days following entry of the final judgment or order that causes
the aggregate amount for all such final judgments or orders outstanding
against all such Persons to exceed $10,000,000 during which a stay of
enforcement of such final judgment or order, by reason of a pending appeal or
otherwise, will not be in effect; (h) the Company and/or one or more of its
Subsidiaries fails to make (A) at the final (but not any interim) fixed
maturity of any issue of Debt a principal payment of $10,000,000 or more or
(B) at the final (but not any interim) fixed maturity of more than one issue
of such Debt principal payments aggregating $10,000,000 or more and, in the
case of clause (A), such defaulted payment will not have been made, waived or
extended within 30 days of the payment default and, in the case of clause (B),
all such defaulted payments will not have been made, waived or extended within
30 days of the payment default that causes the amount described in clause (B)
to exceed $10,000,000; (i) the nonpayment of any two or more items of Debt
that would constitute at the time of such nonpayments, but for the individual
amounts of such Debt, an Event of Default under clause (f) or clause (h)
above, or both, and which items of Debt aggregate $10,000,000 or more; (j) any
Subsidiary Guarantee shall for any reason cease to be in full force and
effect; then, and in each and every such case, unless the principal of all of
the Notes will have already become due and payable, either the Trustee or the
holders of not less than 25% in aggregate principal amount of the Notes then
outstanding under the Indenture, by notice in writing to the Company (and to
the Trustee if given by Noteholders), may declare the entire principal of all
the Notes and the interest accrued thereon, to be due and payable immediately,
and upon any such declaration the same will become immediately due and
payable; provided that, if an Event of Default specified in clause (d) or (e)
above occurs with respect to the Company, all unpaid principal of and accrued
interest on the Notes then outstanding will become and be immediately due and
payable, without any declaration, presentment, demand, protest, notice or
other act on the part of the Trustee or any Holder. Such acceleration may be
annulled and past defaults (other than the non-payment of the principal of the
Notes which will have become due otherwise than by acceleration) may be waived
by the holders of a majority in aggregate principal amount of the Notes then
outstanding, by written notice to the Company and to the Trustee, upon the
conditions provided in the Indenture. For information as to the waiver of
defaults, see "Modification and Waiver."
 
  The Indenture will require that the Company furnish to the Trustee on or
before 90 days after the end of the Company's fiscal year and on or before 45
days after the end of each of the first, second and third fiscal quarters in
each year a brief certificate from the principal executive, financial or
accounting officer of the Company as to his or her knowledge of the Company's
compliance with all conditions and covenants under the Indenture (such
compliance to be determined without regard to any period of grace or
requirement of notice provided under the Indenture).
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
  The terms of Indenture and the Notes will not prevent any consolidation of
the Company with, or merger of the Company into, any other corporation or
corporations (whether or not affiliated with the Company), or successive
consolidations or mergers to which the Company or its successor or successors
will be a party or parties, nor will it prevent any sale, lease or conveyance
of all or substantially all of the property of the Company as an entirety or
substantially as an entirety to any Person; provided that: (a) the Company
will be the continuing Person, or the Person (if other than the Company)
formed by such consolidation or into which the Company is merged or to which
properties and assets of the Company are transferred will be a solvent
corporation organized and existing under the laws of the United States or any
State thereof or the District of Columbia and will expressly assume in writing
all the obligations of the Company under the Notes, (b) immediately before and
immediately after giving effect to such transaction no Event of Default or
event or condition which through the giving of notice or lapse of time or both
would become an Event of Default will have occurred and be continuing,
 
                                      100
<PAGE>
 
(c) the Net Worth of the Company or the surviving entity, as the case may be,
on a pro forma basis after giving effect to such transaction is not less than
the Net Worth of the Company immediately prior to such transaction, and (d)
immediately after giving effect to such transaction on a pro forma basis, the
Company or the surviving entity would be able to incur at least $1.00 of Debt
pursuant to the provisions described in the second paragraph under
"Limitations on Debt." However, the foregoing will not prohibit a transaction,
the principal purpose of which is (as determined in good faith by the Board of
Directors of the Company and evidenced by the resolution thereof) to change
the state of incorporation of the Company, and such transaction does not have
as one of its purposes the evasion of the foregoing limitations.
 
DEFEASANCE
 
 Defeasance and Discharge of Indenture.
 
  Under the terms of the Indenture, the Company will be deemed to have paid
and discharged the entire indebtedness on all the outstanding Notes on the
123rd day after the irrevocable deposit referred to in subparagraph (A) below,
and the provisions of the Indenture, as it relates to such outstanding Notes,
will no longer be in effect (except as to: (a) rights of registration of
transfer and exchange, and the Company's right of optional redemption, (b)
substitution of apparently mutilated, defaced, destroyed, lost or stolen
Notes, (c) the rights of Holders to receive payments of principal thereof and
interest thereon, (d) the rights, obligations and immunities of the Trustee
under the Indenture and (e) the rights of the Noteholders as beneficiaries
with respect to the property so deposited with the Trustee payable to all or
any of them) if (A) with reference to this provision the Company has deposited
or caused to be irrevocably deposited with the Trustee (or another trustee
satisfying the requirements of the Indenture) and conveyed all right, title
and interest for the benefit of the Holders, under the terms of an irrevocable
trust agreement in form and substance satisfactory to the Trustee, as trust
funds in trust solely for the benefit of the Noteholders, (i) cash in an
amount, or (ii) U.S. Government Obligations maturing as to principal and
interest at such times and in such amounts as will insure the availability of
cash in an amount, or (iii) a combination thereof, sufficient, in the opinion
of a nationally recognized firm of independent public accountants expressed in
a written certification thereof delivered to the Trustee, to pay and
discharge, without consideration of reinvestment of such interest and after
payment of all federal, state and local taxes or other charges payable by the
Trustee with respect to such trust fund, the principal of and each installment
of interest on the outstanding Notes at the maturity date or the redemption
date (provided, that in the case of redemption, if such Notes are to be
redeemed prior to the maturity thereof, notice of such redemption shall have
been given as provided in the Indenture or provision satisfactory to the
Trustee shall have been made for giving such Notice) of such principal or
installment of interest, on the day on which such payments are due and payable
in accordance with the terms of the Indenture and the Notes; provided, that
the Trustee or paying agent will have been irrevocably instructed to apply
such money or the proceeds of such U.S. Government Obligations to the
payment of said principal and interest with respect to the Notes; (B) such
deposit will not cause the Trustee to have a conflicting interest for purposes
of the Trust Indenture Act, as amended; (C) such deposit will not result in a
breach or violation of, or constitute a default under, the Indenture or any
other agreement or instrument to which the Company is a party or by which it
is bound; (D) immediately after giving effect to such deposit on a pro forma
basis, no Event of Default, or event that after the giving of notice or lapse
of time or both would become an Event of Default, will have occurred and be
continuing on the date of such deposit or during the period ending on the
123rd day after such date; (E) the Company has delivered to the Trustee (i)
either (x) a ruling directed to the Trustee received from the Internal Revenue
Service to the effect that the Holders of the Notes will not recognize income,
gain or loss for Federal income tax purposes as a result of the Company's
exercise of its option described in this paragraph and will be subject to
Federal income tax on the same amount and in the same manner and at the same
times as would have been the case if such option had not been exercised, or
(y) an Opinion of Counsel to the same effect as the ruling described in clause
(x), and (ii) an Opinion of Counsel to the effect that (x) the trust funds
will not be subject to any rights of holders of Senior Debt, including,
without limitation, those arising under the Indenture and (y) the creation of
the defeasance trust will not violate the Investment Company Act of 1940; (F)
the Company has paid or caused to be paid all sums then payable by the Company
under the Indenture and under the Notes; and (G) the Company has delivered to
the Trustee an
 
                                      101
<PAGE>
 
Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent provided for relating to the defeasance contemplated by
this provision have been complied with.
 
 Defeasance of Certain Obligations.
 
  The Company may omit to comply with the terms, provisions or conditions
described in "Covenants" and clauses (c) and (d) in "Consolidation, Merger and
Sale of Assets" if (a) with reference to the provision described herein, the
Company has deposited or caused to be irrevocably deposited with the Trustee
(or another trustee satisfying the requirements of the Indenture) and conveyed
all right, title and interest for the benefit of the Noteholders, under the
terms of an irrevocable trust agreement in form and substance satisfactory to
the Trustee, as trust funds in trust solely for the benefit of the
Noteholders, (i) cash in an amount, or (ii) U.S. Government Obligations
maturing as to principal and interest at such times and in such amounts as
will insure the availability of cash in an amount, or (iii) a combination
thereof, sufficient, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay and discharge, without consideration of
reinvestment of such interest and after payment of all federal, state and
local taxes or other charges payable by the Trustee with respect to such trust
fund, the principal of and each installment of interest on the outstanding
Notes on the maturity date or the redemption date (provided, that in the case
of redemption, if such Notes are to be redeemed prior to the maturity thereof,
notice of such redemption shall have been given as provided in the Indenture
or provision satisfactory to the Trustee shall have been made for giving such
Notice) of such principal or installment of interest on the day on which such
payments are due and payable in accordance with the terms of the Indenture and
of such Notes; provided, that the Trustee or paying agent will have been
irrevocably instructed to apply such money or the proceeds of such U.S.
Government Obligations to the payment of said principal and interest with
respect to the Notes; (b) such deposit will not cause the Trustee to have a
conflicting interest for purposes of the Trust Indenture Act, as amended; (c)
such deposit will not result in a breach or violation of, or constitute a
default under, the Indenture or any other agreement or instrument to which the
Company is a party or by which it is bound; (d) immediately after giving
effect to such deposit on a pro forma basis, no Event of Default or event
which with notice or lapse of time or both would become an Event of Default
will have occurred and be continuing on the date of such deposit; (e) the
Company has delivered to the Trustee an Opinion of Counsel to the effect that
(i) the Holders of the Notes will not recognize income, gain or loss for
Federal income tax purposes as a result of the Company's exercise of its
option described herein and will be subject to Federal income tax on the same
amount and in the same manner and at the same times as would have been the
case if such option had not been exercised, (ii) Holders of the Notes will
have a valid and perfected first priority security interest in the trust funds
and (iii) the creation of the defeasance trust will not violate the Investment
Company Act of 1940; (f) the Company has paid or caused to be paid all sums
then payable by the Company under the Indenture and under the Notes; and (g)
the Company has delivered to the
Trustee an Officers' Certificate and an Opinion of Counsel, each stating that
all conditions precedent herein described have been complied with.
 
MODIFICATION AND WAIVER
 
  Modifications, waivers and amendments of the Indenture may be made by the
Company and the Trustee with the consent of the Holders of not less than a
majority in aggregate principal amount of the outstanding Notes; provided that
no such modification, waiver or amendment will (a) extend the final maturity
of any Note, or reduce the principal amount thereof, or reduce the rate or
extend the time of payment of interest thereon, or alter the provisions with
respect to redemption or mandatory repurchase thereof (other than those
relating to a Change of Control), or impair or affect the right of any
Noteholder to institute suit for the payment thereof without the consent of
the holder of each Note so affected, or (b) reduce the aforesaid percentage of
Notes, the consent of the holders of which is required for any such
supplemental indenture or (c) modify the subordination provisions of the
Indenture in a manner adverse to the Noteholders, without the consent of the
holders of all Notes then outstanding; and provided, further, that no such
modification, waiver or amendment will make any change in the provisions
described above under the caption "Change of Control" or in the obligations of
the Company to make a Change of Control Offer or the definitions related
thereto that could adversely affect the
 
                                      102
<PAGE>
 
rights of any holder of the Notes without the consent of the holders of not
less than 75% in aggregate principal amount of the outstanding Notes.
 
CONCERNING THE TRUSTEE
 
  The Indenture will provide that, except during the continuance of an Event
of Default, the Trustee will perform only such duties as are specifically set
forth in the Indenture. If an Event of Default has occurred and is continuing,
the Trustee will exercise such rights and powers vested in it under the
Indenture and use the same degree of care and skill in its exercise as a
prudent person would exercise under the circumstances in the conduct of such
person's own affairs.
 
  The Indenture and provisions of the Trust Indenture Act of 1939 contain
limitations on the rights of the Trustee, should it become a creditor of the
Company, to obtain payment of claims in certain cases or to realize on certain
property received by it in respect of any such claims as security or
otherwise. The Trustee is permitted to engage in other transactions; provided,
however, that if it acquires any conflicting interest (as defined in Section
310(b) of the Trust Indenture Act of 1939), it must eliminate such conflict or
resign.
 
  The Holders of at least a majority in aggregate principal amount of the
outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or the Indenture, that may involve the
Trustee in personal liability, or that the Trustee determines in good faith
may be unduly prejudicial to the rights of Holders not joining in the giving
of such direction. A Holder may not pursue any remedy with respect to the
Indenture unless such holder previously will have given to the Trustee written
notice of default and of the continuance thereof, and unless also the holders
of not less than 25% in aggregate principal amount of the Notes then
outstanding will have made written request upon the Trustee to institute such
action or proceedings in its own name as trustee under the Indenture and will
have offered to the Trustee such reasonable indemnity as it may require
against the costs, expenses and liabilities to be incurred therein or thereby
and the Trustee for 60 days after its receipt of such notice, request and
offer of indemnity will have failed to institute any such action or
proceedings and no direction inconsistent with such written request will have
been given to the Trustee.
 
DELIVERY AND FORM OF SECURITIES
 
 Book-Entry, Delivery and Form
 
  Except as set forth herein, the New Notes will initially be issued in the
form of one or more registered notes in global form (the "New Global Note" and
together with the global notes representing the Old Notes, the "Global Note").
The New Global Note will be deposited on the Exchange Date with, or on behalf
of, the Depositary and registered in the name of Cede & Co., as nominee of the
Depositary (such nominee being referred to herein as the "Global Note
Holder"). The Depositary will maintain the Notes in denominations of $1,000
and integral multiples thereof through its book-entry facilities.
 
  The Depositary is a limited-purpose trust company that was created to hold
securities for its participating organizations (collectively, the
"Participants" or the "Depositary's Participants") and to facilitate the
clearance and settlement of transactions in such securities between
Participants through electronic book-entry changes in accounts of its
Participants. The Depositary's Participants include securities brokers and
dealers (including the Initial Purchaser), banks and trust companies, clearing
corporations and certain other organizations. Access to the Depositary's
system is also available to other entities such as banks, brokers, dealers and
trust companies (collectively, the "Indirect Participants" or the
"Depositary's Indirect Participants") that clear through or maintain a
custodial relationship with a Participant, either directly or indirectly.
Persons who are not Participants may beneficially own securities held by or on
behalf of the Depositary only through the Depositary's Participants or the
Depositary's Indirect Participants.
 
 
                                      103
<PAGE>
 
  The Company expects that pursuant to procedures established by the
Depositary (i) upon deposit of the Global Note, the Depositary will credit the
accounts of Participants designated by the Initial Purchaser with portions of
the principal amount of the Global Note and (ii) ownership of the Notes will
be shown on, and the transfer of ownership thereof will be effected only
through, records maintained by the Depositary (with respect to the interests
of the Depositary's Participants), the Depositary's Participants and the
Depositary's Indirect Participants.
 
  The laws of some states require that certain persons take physical delivery
in definitive form of securities that they own. Consequently, the ability to
transfer the Notes will be limited to such extent. For certain other
restrictions on the transferability of the Notes, see "Transfer Restrictions."
 
  So long as the Global Note Holder is the registered owner of any Notes, the
Global Note Holder will be considered the sole Holder of outstanding Notes
under the Indenture. Except as provided below, owners of Notes will not be
entitled to have Notes registered in their names and will not be considered
the owners or Holders thereof under the Indenture for any purpose, including
with respect to the giving of any directions, instructions or approvals to the
Trustee thereunder. Neither the Company nor the Trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of Notes by the Depositary, or for maintaining,
supervising or reviewing any records of the Depositary relating to such Notes.
 
  Payments in respect of the principal of and interest and liquidated damages
on any Notes registered in the name of a Global Note Holder on the applicable
record date will be payable by the Trustee to or at the direction of such
Global Note Holder in its capacity as the registered Holder under the
Indenture. Under the terms of the Indenture, the Company and the Trustee may
treat the persons in whose names any Notes, including the Global Notes, are
registered as the owners thereof for the purpose of receiving such payments
and for any and all other purposes whatsoever. Consequently, neither of the
Company or the Trustee has or will have any responsibility or liability for
the payment of such amounts to beneficial owners of Notes (including
principal, interest and liquidated damages). The Company believes, however,
that it is currently the policy of the Depositary to immediately credit the
accounts of the relevant Participants with such payments, in amounts
proportionate to their respective beneficial interests in the relevant
security as shown on the records of the Depositary. Payments by the
Depositary's Participants and the Depositary's Indirect Participants to the
beneficial owners of Notes will be governed by standing instructions and
customary practice and will be the responsibility of the Depositary's
Participants or the Depositary's Indirect Participants.
 
  Subject to certain conditions, any person having a beneficial interest in a
Global Note may, upon request to the Trustee, exchange such beneficial
interest for Notes in definitive form. Upon any such issuance, the Trustee is
required to register such Notes in the name of, and cause the same to be
delivered to, such person or persons (or the nominee of any thereof). Such
Notes would be issued in fully registered form and would be subject to the
legal requirements described herein under the caption "Transfer Restrictions."
In addition, if (i) the Company
notifies the Trustee in writing that the Depositary is no longer willing or
able to act as a depositary and the Company is unable to locate a qualified
successor within 90 days or (ii) the Company, at its option, notifies the
Trustee in writing that it elects to cause the issuance of Notes in definitive
form under the Indenture, then, upon surrender by the relevant Global Note
Holder of its Global Note, Notes in such form will be issued to each person
that such Global Note Holder and the Depositary identifies as being the
beneficial owner of the related Notes.
 
  Neither the Company nor the Trustee will be liable for any delay by the
Global Note Holder or the Depositary in identifying the beneficial owners of
Notes and the Company and the Trustee may conclusively rely on, and will be
protected in relying on, instructions from the Global Note Holder or the
Depositary for all purposes.
 
  The Indenture requires that payments in respect of the Notes represented by
the Global Note (including principal, interest and liquidated damages) be made
in same-day funds. The Notes are expected to be eligible to trade in the
PORTAL Market and to trade in the Depositary's Same-Day Funds Settlement
System, and any permitted secondary market trading activity in the Notes will,
therefore, be required by the Depositary to be settled in same-day funds.

REGISTRATION RIGHTS; LIQUIDATED DAMAGES
   
  The Company and the Initial Purchaser entered into a Registration Rights
Agreement dated as of December 1, 1997. Pursuant to the Registration Rights
Agreement, the Company agreed to file with the Commission an Exchange Offer
Registration Statement with respect to the New Notes. Upon the effectiveness
of the Exchange Offer Registration Statement, the Company will offer, pursuant
to the Exchange Offer, to the Holders of Transfer Restricted Securities who
are able to make certain representations the opportunity to exchange their
Transfer Restricted Securities for New Notes. If (i) the Company is not
required to file the Exchange Offer Registration Statement because the
Exchange Offer is not permitted by applicable law or Commission policy or (ii)
any Holder of Transfer Restricted Securities notifies the Company within 20
days of the commencement of the Exchange Offer that (a) it is prohibited by
law or Commission policy from participating in the Exchange Offer or (b) it
may not resell the New Notes acquired by it in the Exchange Offer to the
public without delivering a prospectus and the prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales or (c) it is a broker-dealer and holds Notes acquired directly from
the Company or an affiliate of the Company, the Company will file with the
Commission a Shelf Registration Statement to cover resales of the Notes by the
Holders thereof who satisfy certain conditions relating to the provision of
information in connection with the Shelf Registration Statement. The Company
will use its best efforts to cause the applicable registration statement to be
declared effective as promptly as possible by the Commission. For purposes of
the foregoing, "Transfer Restricted Securities" means each Note or New Note
until (i) the date on which such Note or New Note has been exchanged by a
person other than a broker-dealer for a New Note in the Exchange Offer, (ii)
following the exchange by a broker-dealer in the Exchange Offer of a Note for
a New Note, the date on which such New Note is sold to a purchaser who
receives from such broker-dealer on or prior to the date of such sale a copy
of the prospectus contained in the Exchange Offer Registration Statement,
(iii) the date on which such Note has been effectively registered under the
Securities Act and disposed of in accordance with the Shelf Registration
Statement or (iv) the date on which such Note or New Note is distributed to
the public pursuant to Rule 144 under the Act.     
 
  The Registration Rights Agreement provides that (i) the Company will file an
Exchange Offer Registration Statement with the Commission on or prior to 45
days after the Issue Date, (ii) the Company will use its best efforts to have
the Exchange Offer Registration Statement declared effective by the Commission
on or prior to 90 days after the Issue Date, (iii) unless the Exchange Offer
would not be permitted by a policy of the Commission, the Company will
commence the Exchange Offer and will use its best efforts to issue on or prior
to 45 days after the date on which the Exchange Offer Registration Statement
is declared effective by the Commission (the "Exchange Offer Effective Date")
New Notes in exchange for all Notes tendered prior thereto in the Exchange
Offer and (iv) if obligated to file the Shelf Registration Statement, the
Company will use its best efforts to file the Shelf Registration Statement
with the Commission on or prior to 45 days after such obligation arises and to
cause the Shelf Registration Statement to be declared effective by the
Commission on or prior to 90 days after such obligation arises. If (a) the
Company fails to file within 45 days, or cause to become effective within 90
days, the Exchange Offer Registration Statement or (b) the Company is
obligated to file the Shelf Registration Statement and such Shelf Registration
Statement is not filed within 45 days, or declared effective within 90 days,
of the date on which the Company became so obligated or (c) the Company fails
to consummate the Exchange Offer within 45 days of the Exchange Offer
Effective Date or (d) the Shelf Registration Statement or the Exchange Offer
Registration Statement is declared effective but thereafter ceases to be
effective or usable in connection with resales of Transfer Restricted
Securities during the periods specified in the Registration Rights Agreement
(each such event referred to in clauses (a) through (d) above a "Registration
Default"), then the Company will pay liquidated damages ("Liquidated Damages")
to each Holder of Transfer Restricted Securities, during the first 90-day
period immediately following the occurrence of such Registration Default in an
amount equal to $.05 per week per $1,000 principal amount of Notes
constituting Transfer Restricted Securities held by such Holder. The amount of
the Liquidated Damages will increase an additional $.05 per week per $1,000
principal amount constituting Transfer Restricted Securities for each
subsequent 90-day period until the applicable Registration Default has been
cured, up to a maximum amount of Liquidated Damages of $.30 per week per
$1,000 principal amount of Notes constituting Transfer Restricted
 
                                      105

Securities. All accrued Liquidated Damages will be paid by the Company on each
Damages Payment Date to the Global Note Holder by wire transfer of immediately
available funds or by federal funds check and to the Holders of certificated
securities by mailing a check to such Holders' registered addresses. Following
the cure of all Registration Defaults, the accrual of Liquidated Damages will
cease.
 
  Holders of the Notes will be required to make certain representations to the
Company (as described in the Registration Rights Agreement) in order to
participate in the Exchange Offer and will be required to deliver information
to be used in connection with the Shelf Registration Statement within the time
periods set forth in the Registration Rights Agreement in order to have their
Senior Notes included in the Shelf Registration Statement and benefit from the
provisions regarding Liquidated Damages set forth above.
 
                              THE EXCHANGE OFFER
 
TERMS OF THE EXCHANGE OFFER; PERIOD FOR TENDERING OLD NOTES
   
  Upon the terms and subject to the conditions set forth in this Prospectus
and in the accompanying Letter of Transmittal (which together constitute the
Exchange Offer), the Company will accept for exchange Old Notes that are
properly tendered on or prior to the Expiration Date and not withdrawn as
permitted below. As used herein, the term "Expiration Date" means 5:00 p.m.,
New York City time, on February 23, 1998; provided, however, that if the
Company, in its sole discretion, has extended the period of time during which
the Exchange Offer is open, the term "Expiration Date" means the latest time
and date to which the Exchange Offer is extended.     
   
  As of the date of this Prospectus, $175,000,000 aggregate principal amount
of Old Notes is outstanding. This Prospectus, together with the Letter of
Transmittal, is first being sent on or about January 23, 1998, to all holders
of Old Notes known to the Company. The Company's obligation to accept Old
Notes for exchange pursuant to the Exchange Offer is subject to certain
customary conditions as set forth below under "--Certain Conditions to the
Exchange Offer."     
 
  The Company expressly reserves the right, at any time and from time to time,
to extend the period of time during which the Exchange Offer is open, and
thereby to delay acceptance for exchange of any Old Notes, by giving oral or
written notice of such extension to the holders of the Old Notes as described
below. During any such extension, all Old Notes previously tendered will
remain subject to the Exchange Offer and may be accepted for exchange by the
Company. Any Old Notes not accepted for exchange for any reason will be
returned without expense to the tendering holders thereof as promptly as
practicable after the expiration or termination of the Exchange Offer.
 
  Old Notes tendered in the Exchange Offer must be in denominations of $1,000
or any integral multiple thereof.
 
  The Company expressly reserves the right to amend or terminate the Exchange
Offer, and not to accept for exchange any Old Notes not theretofore accepted
for exchange, upon the occurrence of any of the conditions to the Exchange
Offer specified below under "--Certain Conditions to the Exchange Offer." The
Company will give oral or written notice of any extension, amendment, non-
acceptance or termination to the holders of the Old Notes as promptly as
practicable, such notice in the case of any extension to be issued by means of
a press release or other public announcement no later than 9:00 a.m., New York
City time, on the next business day after the previously scheduled Expiration
Date.
 
PROCEDURES FOR TENDERING OLD NOTES
 
  Only a registered holder of Old Notes may tender such Old Notes in the
Exchange Offer. The tender to the Company of Old Notes by a holder thereof as
set forth below and the acceptance thereof by the Company will
 
                                      106
<PAGE>
 
   
constitute a binding agreement between the tendering holder and the Company
upon the terms and subject to the conditions set forth in this Prospectus and
in the accompanying Letter of Transmittal. Except as set forth below, a holder
who wishes to tender Old Notes for exchange pursuant to the Exchange Offer
must transmit either (i) a properly completed and duly executed Letter of
Transmittal, including all other documents required by such Letter of
Transmittal, to PNC Bank, National Association (the "Exchange Agent") at one
of the addresses set forth below under "Exchange Agent," or (ii) if such Old
Notes are tendered pursuant to the procedures for book-entry transfer set
forth below, a holder tendering Old Notes may transmit an Agent's Message
(defined herein) to the Exchange Agent in lieu of the Letter of Transmittal,
in either case on or prior to the Expiration Date. In addition, either (i)
certificates for such Old Notes must be received by the Exchange Agent along
with the Letter of Transmittal, (ii) a timely confirmation of a book-entry
transfer (a "Book-Entry Confirmation") of such Old Notes, if such procedure is
available, into the Exchange Agent's account at The Depository Trust Company
("DTC" or the "Book-Entry Transfer Facility") pursuant to the procedure for
book-entry transfer described below, along with the Letter of Transmittal or
an Agent's Message, as the case may be, must be received by the Exchange Agent
prior to the Expiration Date, or (iii) the holder must comply with the
guaranteed delivery procedures described below. The term "Agent's Message"
means a message, transmitted to the Book-Entry Transfer Facility and received
by the Exchange Agent and forming a part of the Book-Entry Confirmation, which
states that the Book-Entry Transfer Facility has received an express
acknowledgement from the tendering Participant (defined herein) that such
Participant has received and agrees to be bound by the Letter of Transmittal
and that the Company may enforce the Letter of Transmittal against such
Participant.     
 
  THE METHOD OF DELIVERY OF OLD NOTES, LETTERS OF TRANSMITTAL OR AGENT'S
MESSAGE AND ALL OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE
HOLDERS. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL,
PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY. NO LETTERS OF
TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO THE COMPANY.
 
  Any beneficial owner of Old Notes whose Old Notes are registered in the name
of a broker, dealer, commercial bank, trust company, or other nominee and who
wishes to tender such Old Notes in the Exchange Offer should contact the
registered holder promptly and instruct such registered holder to tender on
such beneficial owner's behalf. If such beneficial owner wishes to tender on
its own behalf, such owner must, prior to completing and executing the Letter
of Transmittal and delivering such beneficial owner's Old Notes, either make
appropriate arrangements to register ownership of such Old Notes in such
beneficial owner's name or obtain a properly completely bond power from the
registered holder. The transfer of registered ownership may take considerable
time.
 
  Signatures on a Letter of Transmittal or a notice of withdrawal described
below (see "--Withdrawal Rights"), as the case may be, must be guaranteed
(see"--Guaranteed Delivery Procedures") unless the Old Notes surrendered for
exchange pursuant thereto are tendered (i) by a registered holder of those Old
Notes who has not completed the box entitled "Special Issuance Instructions"
or "Special Delivery Instructions" on the Letter of Transmittal or (ii) for
the account of an Eligible Institution (as defined below). In the event that
signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, are required to be guaranteed, such guaranties must be by a financial
institution (including most banks, savings and loan associations and brokerage
houses) that is a participant in the Securities Transfer Agents Medallion
Program, the New York Stock Exchange Medallion Program or the Stock Exchanges
Medallion Program (collectively, "Eligible Institutions"). If Old Notes are
registered in the name of a person other than a signer of the Letter of
Transmittal, the Old Notes surrendered for exchange must be endorsed by or be
accompanied by a written instrument or instruments of transfer or exchange in
satisfactory form as determined by the Company in its sole discretion, duly
executed by the registered holder exactly as the name or names of the
registered holder or holders appear on the Old Notes with the signature
thereon guaranteed by an Eligible Institution.
 
  All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of Old Notes tendered for exchange will be determined
by the Company in its sole discretion, which determination shall be
 
                                      107
<PAGE>
 
final and binding. The Company reserves the absolute right to reject any and
all tenders of any particular Old Notes not properly tendered or not to accept
any particular Old Notes not properly tendered or the acceptance of which
might, in the judgment of the Company or its counsel, be unlawful. The Company
also reserves the absolute right to waive any defects or irregularities or
conditions of the Exchange Offer as to any particular Old Notes either before
or after the Expiration Date (including the right to waive the ineligibility
of any holder who seeks to tender Old Notes in the Exchange Offer). The
interpretation by the Company of the terms and conditions of the Exchange
Offer as to any particular Old Notes either before or after the Expiration
Date (including the Letter of Transmittal and the instructions thereto) shall
be final and binding on all parties. Unless waived, any defects or
irregularities in connection with tenders of Old Notes for exchange must be
cured within such reasonable period of time as the Company shall determine.
None of the Company, the Exchange Agent or any other person shall be under any
duty to give notification of any defect or irregularity with respect to any
tender of Old Notes for exchange, nor shall any of them incur any liability
for failure to give such notification.
 
  If the Letter of Transmittal or any Old Notes or powers of attorney are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and, unless waived by
the Company, proper evidence satisfactory to the Company of their authority to
so act must be submitted with the Letter of Transmittal.
 
  By tendering Old Notes for exchange, each holder will represent to the
Company that, among other things, the New Notes acquired pursuant to the
Exchange Offer are being acquired in the ordinary course of business of the
person receiving such New Notes, whether or not such person is the holder, and
that neither the holder nor such other person has any arrangement or
understanding with any person to engage or participate in a distribution of
the New Notes. If any holder or any such other person is an "affiliate", as
defined under Rule 405 of the Securities Act, of the Company or is engaged in
or intends to engage in, or has an arrangement or understanding with any
person to participate in, a distribution of such New Notes to be acquired
pursuant to the Exchange Offer, such holder or any such other person (i) may
not rely on the applicable interpretation of the staff of the Commission and
(ii) must comply with the registration and prospectus delivery requirements of
the Securities Act in connection with any resale transaction. Each broker-
dealer that receives New Notes for its own account in exchange for Old Notes,
where such Old Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities, must acknowledge that it
will deliver a prospectus in connection with any resale of such New Notes. See
"Plan of Distribution." The Letter of Transmittal states that by so
acknowledging and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the
Securities Act.
 
ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTE
 
  Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
the Company will accept, promptly after the Expiration Date, all Old Notes
properly tendered and will issue the New Notes promptly after acceptance of
the Old Notes. See "--Certain Conditions to the Exchange Offer" below. For
purposes of the Exchange Offer, the Company will be deemed to have accepted
properly tendered Old Notes for exchange when, as and if the Company has given
oral or written notice thereof to the Exchange Agent.
 
  For each Old Note accepted for exchange, the holder of such Old Note will
receive as set forth below under "Description of the New Notes--Book-Entry;
Delivery and Form" a New Note having a principal amount equal to that of the
surrendered Old Note. Registered holders of New Notes on the relevant record
date for the first interest payment date following the consummation of the
Exchange Offer will receive interest accruing from the most recent date to
which interest has been paid on the Old Notes or, if no interest has been paid
on the Old Notes, from December 1, 1997. Old Notes accepted for exchange will
cease to accrue interest from and after the date of consummation of the
Exchange Offer. Accordingly, holders whose Old Notes are accepted for exchange
will not receive any payment in respect of accrued interest on such Old Notes
otherwise payable on any interest payment date for which the record date
occurs on or after consummation of the Exchange Offer. Old Notes not tendered
or not accepted for exchange will continue to accrue interest from and after
the date of consummation of the Exchange Offer.
 
                                      108
<PAGE>
 
  In all cases, issuance of New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of certificates for such Old Notes or a timely Book-
Entry Confirmation of such Old Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility, a properly completed and duly executed Letter of
Transmittal and all other required documents or, in the case of a Book-Entry
Confirmation, an Agent's Message in lieu thereof. If any tendered Old Notes
are not accepted for any reason set forth in the terms and conditions of the
Exchange Offer or if Old Notes are submitted for a greater principal amount
than the holder desires to exchange, such unaccepted or non-exchanged Old
Notes will be returned without expense to the tendering holder thereof (or, in
the case of Old Notes tendered by book-entry transfer into the Exchange
Agent's account at the Book-Entry Transfer Facility pursuant to the book-entry
procedures described below, such non-exchanged Old Notes will be credited to
an account maintained with such Book-Entry Transfer Facility) as promptly as
practicable after the expiration or termination of the Exchange Offer.
 
BOOK-ENTRY TRANSFER
 
  The Exchange Agent will make a request to establish an account with respect
to the Old Notes at the Book-Entry Transfer Facility for purposes of the
Exchange Offer within two business days after the date of this Prospectus, and
any financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of Old Notes by causing the
Book-Entry Transfer Facility to transfer such Old Notes into the Exchange
Agent's account at the Book-Entry Transfer Facility in accordance with such
Book-Entry Transfer Facility's procedures for transfer. However, although
delivery of Old Notes may be effected through book-entry transfer at the Book-
Entry Transfer Facility, the Letter of Transmittal or a facsimile thereof,
with any required signature guarantees, or an Agent's Message in lieu of a
Letter of Transmittal, and any other required documents, must in any case, be
transmitted to and received by the Exchange Agent at the addresses set forth
below under "--Exchange Agent" on or prior to the Expiration Date or the
guaranteed delivery procedures described below must be complied with.
 
GUARANTEED DELIVERY PROCEDURES
 
  If a registered holder of the Old Notes desires to tender such Old Notes and
the Old Notes are not immediately available, or time will not permit such
holder's Old Notes or other required documents to reach the Exchange Agent
before the Expiration Date, or the procedure for book-entry transfer cannot be
completed on a timely basis, a tender may be effected if (i) the tender is
made through an Eligible Institution, (ii) on or prior to 5:00 p.m., New York
City time, on the Expiration Date, the Exchange Agent receives from such
Eligible Institution a properly completed and duly executed Letter of
Transmittal (or a facsimile thereof) and Notice of Guaranteed Delivery,
substantially in the form provided by the Company (by telegram, telex,
facsimile transmission, mail or hand delivery), setting forth the name and
address of the holder of the Old Notes and the amount of Old Notes tendered,
stating that the tender is being made thereby and guaranteeing that within
three New York Stock Exchange ("NYSE") trading days after the date of
execution of the Notice of Guaranteed Delivery, the certificates for all
physically tendered Old Notes, in proper form for transfer, or a Book-Entry
Confirmation, as the case may be, and any other documents required by the
Letter of Transmittal will be deposited by the Eligible Institution with the
Exchange Agent, and (iii) the certificates for all physically tendered Old
Notes, in proper form for transfer, or a Book-Entry Confirmation, as the case
may be, and any other documents required by the Letter of Transmittal will be
deposited by the Eligible Institution within three NYSE trading days after the
date of execution of the Notice of Guaranteed Delivery.
 
WITHDRAWAL RIGHTS
 
  Tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New
York City time, on the Expiration Date. For a withdrawal to be effective, a
written notice of withdrawal must be received by the Exchange Agent at one of
the addresses set forth below under "--Exchange Agent." Any such notice of
withdrawal must specify the name of the person having tendered the Old Notes
to be withdrawn, identify the
 
                                      109
<PAGE>
 
Old Notes to be withdrawn (including the principal amount of such Old Notes),
and (where certificates for Old Notes have been transmitted) specify the name
in which such Old Notes are registered, if different from that of the
withdrawing holder. If certificates for Old Notes have been delivered or
otherwise identified to the Exchange Agent, then prior to the release of such
certificates the withdrawing holder must also submit the serial numbers of the
particular certificates to be withdrawn and a signed notice of withdrawal,
with signatures guaranteed by an Eligible Institution unless such holder is an
Eligible Institution in which case such guarantee will not be required. If Old
Notes have been tendered pursuant to the procedure for book-entry transfer
described above, any notice of withdrawal must specify the name and number of
the account at the Book-Entry Transfer Facility to be credited with the
withdrawn Old Notes and otherwise comply with the procedures of such facility.
All questions as to the validity, form and eligibility (including time of
receipt) of such notices will be determined by the Company, whose
determination will be final and binding on all parties. Any Old Notes so
withdrawn will be deemed not to have been validly tendered for exchange for
purposes of the Exchange Offer. Any Old Notes which have been tendered for
exchange but which are not exchanged for any reason will be returned to the
holder thereof without cost to such holder (or, in the case of Old Notes
tendered by book-entry transfer into the Exchange Agent's account at the Book-
Entry Transfer Facility pursuant to the book-entry transfer procedures
described above, such Old Notes will be credited to an account maintained with
such Book-Entry Transfer Facility for the Old Notes) as soon as practicable
after withdrawal, rejection of tender or termination of the Exchange Offer.
Properly withdrawn Old Notes may be retendered by following one of the
procedures described under "--Procedures for Tendering Old Notes" above at any
time on or prior to the Expiration Date.
 
CERTAIN CONDITIONS TO THE EXCHANGE OFFER
 
  Notwithstanding any other provisions of the Exchange Offer, and subject to
its obligations pursuant to the Registration Rights Agreement, the Company
shall not be required to accept for exchange, or to issue New Notes in
exchange for, any Old Notes, and may terminate or amend the Exchange Offer,
if, at any time before the acceptance of such New Notes for exchange, any of
the following events shall occur:
 
    (i) any injunction, order or decree shall have been issued by any court
  or any governmental agency that would prohibit, prevent or otherwise
  materially impair the ability of the Company to proceed with the Exchange
  Offer; or
 
    (ii) the Exchange Offer will violate any applicable law or any applicable
  interpretation of the staff of the Commission.
 
  The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company in whole or in part at any time and from time to time
in its sole discretion. The failure by the Company at any time to exercise any
of the foregoing rights shall not be deemed a waiver of any such right and
such right shall be deemed an ongoing right which may be asserted at any time
and from time to time.
 
  In addition, the Company will not accept for exchange any Old Notes
tendered, and no New Notes will be issued in exchange for any such Old Notes,
if at such time any stop order is threatened by the Commission or in effect
with respect to the Registration Statement of which this Prospectus is a part
or with respect to the qualification of the Indenture under the Trust
Indenture Act of 1939, as amended.
 
  The Exchange Offer is not conditioned on any minimum principal amount of Old
Notes being tendered for exchange.

  DELIVERY OF THE LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET FORTH
ABOVE OR TRANSMISSION OF INSTRUCTIONS VIA FACSIMILE OTHER THAN AS SET FORTH
ABOVE DOES NOT CONSTITUTE A VALID DELIVERY OF SUCH LETTER OF TRANSMITTAL.
 
FEES AND EXPENSES
 
  The Company will not make any payment to brokers, dealers, or other
soliciting acceptances of the Exchange Offer.
 
  The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Company.
 
TRANSFER TAXES
 
  Holders who tender their Old Notes for exchange will not be obligated to pay
any transfer taxes in connection therewith, except that holders who instruct
the Company to register New Notes in the name of, or request that Old Notes
not tendered or not accepted in the Exchange Offer be returned to, a person
other than the registered tendering holder will be responsible for the payment
of any applicable transfer taxes thereon.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
  Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to the provisions
in the Indenture regarding transfer and exchange of the Old Notes and the
restrictions on transfer of such Old Notes as set forth in the legend thereon
as a consequence of the issuance of the Old Notes pursuant to exemptions from,
or in transactions not subject to, the registration requirements of the
Securities Act. In general, the Old Notes may not be offered or sold, unless
registered under the Securities Act. The Company does not currently anticipate
that it will register Old Notes under the Securities Act. Based on
interpretations by the staff of the Commission, as set forth in no-action
letters issued to third parties, the Company believes that New Notes issued
pursuant to the Exchange Offer in exchange for Old Notes may be offered for
resale, resold or otherwise transferred by a holder thereof (other than a
holder that is an "affiliate" of the Company within the meaning of Rule 405
under the Securities Act) without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Notes are
 
                                      111
<PAGE>
 
acquired in the ordinary course of such holder's business and such holder,
other than a broker-dealer, has no arrangement or understanding with any
person to engage or participate in a distribution of such New Notes. However,
the Commission has not considered the Exchange Offer in the context of a no-
action letter request by the Company and there can be no assurance that the
staff of the Commission would make a similar determination with respect to the
Exchange Offer as in such other circumstances. Each holder, other than a
broker-dealer, must acknowledge that it is not engaged in, and does not intend
to engage in, a distribution of such New Notes and has no arrangement or
understanding to participate in a distribution of New Notes. If any holder is
an affiliate of the Company or is engaged in or intends to engage in or has
any arrangement or understanding with respect to the distribution of the New
Notes to be acquired pursuant to the Exchange Offer, such holder (i) may not
rely on the applicable interpretations of the staff of the Commission and (ii)
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction. Each broker-dealer
that receives New Notes for its own account in exchange for Old Notes pursuant
to the Exchange Offer must acknowledge that such Old Notes were acquired by
such broker-dealer as a result of market-making activities or other trading
activities and that it will deliver a prospectus in connection with any resale
of such New Notes. The Letter of Transmittal states that by so acknowledging
and by delivering a prospectus, a broker-dealer will not be deemed to admit
that it is an "underwriter" within the meaning of the Securities Act. This
Prospectus, as it may be amended or supplemented from time to time, may be
used by a broker-dealer in connection with resales of New Notes received in
exchange for Old Notes where such Old Notes were acquired by such broker-
dealer as a result of market-making activities or other trading activities.
The Company has agreed that, for a period of 180 days after the Expiration
Date, it will make this Prospectus available to any broker-dealer for use in
connection with any such resale. See "Plan of Distribution."

  Payments of Interest. The Old Notes were not issued with original issue
discount. As a result, payments of interest on a New Note generally will be
taxable to a U.S. Holder as ordinary interest income at the time such payments
are accrued or are received, in accordance with the U.S. Holder's regular
method of tax accounting.
 
  Market Discount. A Note will be considered to bear "market discount" if the
U.S. Holder's tax basis for the Note is less than the principal amount of the
Note by more than a de minimis amount.
 
  Under the market discount rules, a U.S. Holder will be required to treat any
partial principal payment on, or any gain realized on the sale, exchange,
retirement or other disposition of, a Note as ordinary income to the extent of
the lesser of (i) the amount of such payment or realized gain or (ii) the
market discount which has not previously been included in income and is
treated as having accrued on such New Note at the time of such payment or
disposition. Market discount will be considered to accrue on a straight-line
basis during the period from the date of acquisition to the maturity date of
the Note, unless the U.S. Holder elects to accrue market discount on the basis
of semiannual compounding.
 
  A U.S. Holder may be required to defer the deduction of all or a portion of
the interest paid or accrued on any indebtedness incurred or maintained to
purchase or carry a New Note with market discount until the maturity of the
New Note or certain earlier dispositions. A. U.S. Holder may elect to include
market discount in income currently as it accrues, in which case the rules
described above regarding the treatment as ordinary income of gain upon the
disposition of the Note and upon the receipt of certain cash payments and
regarding the deferral of interest deductions will not apply. Persons
considering making this election should consult their tax advisors.
 
  Premium. If a U.S. Holder's initial tax basis in any Note is greater than
the principal amount of the Note, the Note will be considered to have
"amortizable bond premium" equal in amount to such excess. A U.S. Holder may
elect to amortize such premium using a constant yield method over the
remaining term of the New Note and may offset interest otherwise required to
be included in respect of the New Note during any taxable year by the
amortized amount of such excess for the taxable year. Any election to amortize
bond premium applies to all taxable debt instruments acquired by the U.S.
Holder on or after the first day of the first taxable year to which such
election applies and may be revoked only with the consent of the IRS.
   
  Disposition of a Note. Except as discussed above, upon the sale, exchange or
retirement of a New Note, a U.S. Holder generally will recognize taxable gain
or loss equal to the difference between the amount realized on the sale,
exchange or retirement (other than amounts representing accrued and unpaid
interest) and such U.S. Holder's adjusted tax basis in the New Note. A U.S.
Holder's adjusted tax basis in a New Note generally will equal such U.S.
Holder's initial investment in the Note increased by any accrued market
discount that the U.S. Holder has included in income and decreased by the
amount of any amortizable bond premium taken with respect to such Note. Such
gain or loss generally will taxed at preferential tax rates if the Note has
been held for more than eighteen months.     
 
NON-U.S. HOLDERS
 
  A non-U.S. Holder will not be subject to United States federal income taxes
on payments of principal, premium (if any) or interest (including original
issue discount, if any) on a New Note, unless such non-U.S. Holder is a direct
or indirect 10% or greater shareholder of the Company or a controlled foreign
corporation related to the Company. To qualify for the exemption from
taxation, the last United States payor in the chain of payment prior to
payment to a non-U.S. Holder (the "Withholding Agent") must have received in
the year in
which a payment of interest or principal occurs, or in either of the two
preceding calendar years, a statement that (i) is signed by the beneficial
owner of the New Note under penalties of perjury, (ii) certifies that such
owner is not a U.S. Holder and (iii) provides the name and address of the
beneficial owner. The statement may be made
 
                                      113
<PAGE>
 
on an IRS Form W-8 or a substantially similar form, and the beneficial owner
must inform the Withholding Agent of any change in the information on the
statement within 30 days of such change. If a New Note is held through a
securities clearing organization or certain other financial institutions, the
organization or institution may provide a signed statement to the Withholding
Agent. However, in such case, the signed statement must be accompanied by a
copy of the IRS Form W-8 or the substitute form provided by the beneficial
owner to the organization or institution.
 
  Generally, a non-U.S. Holder will not be subject to federal income taxes on
any amount which constitutes capital gain upon retirement or disposition of a
New Note, provided the gain is not effectively connected with the conduct of a
trade or business in the United States by the non-U.S. Holder. Certain other
exceptions may be applicable, and a non-U.S. Holder should consult its tax
advisor in this regard.
 
  The New Notes will not be includible in the estate of a non-U.S. Holder
unless the individual is a direct or indirect 10% or greater shareholder of
the Company or, at the time of such individual's death, payments in respect of
the New Notes would have been effectively connected with the conduct by such
individual of a trade or business in the United States.
 
BACKUP WITHHOLDING; INFORMATION REPORTING
 
  Backup withholding of United States federal income tax at a rate of 31% may
apply to payments made in respect of the New Notes to registered owners who
are not "exempt recipients" and who fail to provide certain identifying
information (such as the registered owner's taxpayer identification number) in
the required manner. Generally, individuals are not exempt recipients, whereas
corporations and certain other entities generally are exempt recipients.
Payments made in respect of the New Notes to a U.S. Holder must be reported to
the IRS, unless the U.S. Holder is an exempt recipient or establishes an
exemption. Compliance with the identification procedures described in the
preceding section would establish an exemption from backup withholding for
those non-U.S. Holders who are not exempt recipients.
 
  In addition, upon the sale of a New Note to (or through) a broker, the
broker must withhold 31% of the entire purchase price, unless either (i) the
broker determines that the seller is a corporation or other exempt recipient
or (ii) the seller provides, in the required manner, certain identifying
information and, in the case of a non-U.S. Holder, certifies that such seller
is a non-U.S. Holder (and certain other conditions are met). Such a sale must
also be reported by the broker to the IRS unless either (a) the broker
determines that the seller is an exempt recipient or (b) the seller certifies
its non-U.S. status (and certain other conditions are met). Certification of
the registered owner's non-U.S. status would be made normally on an IRS Form
W-8 under penalties of perjury, although in certain cases it may be possible
to submit other documentary evidence.
 
  Any amounts withheld under the backup withholding rules from a payment to a
beneficial owner would be allowed as a refund or a credit against such
beneficial owner's United States federal income tax provided the required
information is furnished to the IRS.

                             PLAN OF DISTRIBUTION
   
  Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of New Notes received in exchange for Old Notes where
such Old Notes were acquired by such broker-dealer as a result of market-
making activities or other trading activities. The Company has agreed that,
starting on the Expiration Date and ending on the close of business on the
180th day following the Expiration Date, it will make this Prospectus, as
amended or supplemented, available to any broker-dealer for use in connection
with any such resale. In addition, until August 22, 1998, all dealers
effecting transactions in the New Notes may be required to deliver a
prospectus.     
 
  The Company will not receive any proceeds from any sale of New Notes by
broker-dealers. New Notes received by broker-dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions
through the writing of options on the New Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at
prices related to such prevailing market prices or at negotiated prices. Any
such resale may be made directly to purchasers or to or through brokers or
dealers who may receive compensation in the form of commissions or concessions
from any such broker-dealer and/or the purchasers of any such New Notes. Any
broker-dealer that resells New Notes that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such New Notes may be deemed to be an
"underwriter" within the meaning of the Act and any profit of any such resale
of New Notes and any commissions or concessions received by any such persons
may be deemed to be underwriting compensation under the Securities Act. The
Letter of Transmittal states that, by acknowledging that it will deliver and
by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act.
   
  For a period of 180 days after the Expiration Date, the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such
documents in the Letter of Transmittal. Additional copies of this Prospectus,
the Letter of Transmittal and other related documents may be obtained upon
request to the Exchange Agent at (412) 762-3666. The Company has agreed to pay
all expenses incident to the Exchange Offer (including the expenses of any one
special counsel for the holders of the Notes) other than commissions or
concessions of any brokers or dealers and will indemnify the holders of the
Notes participating in the Exchange Offer (including any broker-dealers)
against certain liabilities, including liabilities under the Securities Act.
    
                                 LEGAL MATTERS
 
  Certain legal matters in connection with the New Notes will be passed upon
on behalf of the Company by Dickie, McCamey & Chilcote, P.C., Pittsburgh,
Pennsylvania. Clayton A. Sweeney is both a shareholder and Director in the
firm and a Director of the Company.

                        REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors
Koppers Industries, Inc.
 
  We have audited the accompanying consolidated balance sheet of Koppers
Industries, Inc. at December 31, 1995 and 1996, and the related consolidated
statements of operations, stockholders' equity and cash flows for each of the
three years in the period ended December 31, 1996. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. 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 Industries, Inc. at December 31, 1995 and 1996, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1996, in conformity with
generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.SIGNIFICANT ACCOUNTING POLICIES
 
 Organization
 
  Koppers Industries, Inc. (the "Company") is an integrated producer of carbon
compounds and treated wood products for use in a variety of industrial
applications. The Company's Carbon Materials & Chemicals division is a
supplier of carbon pitch, which is used primarily by the aluminum industry as
a binder in the manufacture of anodes. Carbon Materials & Chemicals also
produces several by-products, including creosote, a chemical preservative used
to pressure treat wood for the railroad and utility markets; phthalic
anhydride, used in the production of plasticizers and polyester resins; and
roofing pitch, or bitumen, used in the manufacture of built-up roofing
systems. The Company's Railroad & Utility Products division treats railroad
crossties, utility poles and pilings with preservatives for various uses. The
Company's Coke Products division produces foundry and furnace coke for sale to
steel mill blast furnaces and foundries, and coke by-products, including coal
tars, gases, oils and chemicals for sale to other industrial operations.
 
 Basis of Financial Statements
 
  The consolidated financial statements include the accounts of the Company
and all majority-owned subsidiaries. All significant intercompany transactions
have been eliminated.
 
  The Company's investments in 20% to 50% owned companies in which it has the
ability to exercise significant influence over operating and financial
policies are accounted for on the equity method. Accordingly, the Company's
share of the earnings of these companies is included in consolidated net
income.
 
 Use of Estimates
 
  The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
 Inventories
 
  Carbon Materials & Chemicals and Railroad & Utility Products inventories are
valued at the lower of cost, utilizing the last-in, first-out ("LIFO") basis,
or market. Market represents replacement cost for raw materials and net
realizable value for work in process and finished goods. Carbon Materials &
Chemicals and Railroad & Utility Products inventories constituted
approximately 90% of total first-in, first-out ("FIFO") inventory value at
December 31, 1996.
 
 Revenue Recognition
 
  The Company recognizes revenue from product sales at the time of shipment.
 
 Investments
 
  Following is a combined financial summary of the equity investments of the
Company for their respective years ended 1994, 1995 and 1996. The fiscal year
end for Koppers Australia Pty. Limited is June 30 and, accordingly, the equity
numbers reflected in the table will not equal the amounts shown in the
financial statements.

</TABLE>
 
  The Company is guarantor on KSA debt in the amount of $1.9 million at
December 31, 1996.
 
 Depreciation and Amortization
 
  Buildings, machinery, and equipment are recorded at purchased cost and
depreciated over their estimated useful lives (5 to 20 years) using the
straight-line method.
 
  Effective July 1, 1994 the Company extended the estimated useful lives of
certain fixed assets to conform to the Company's actual experience with fixed
asset lives. This change resulted in a reduction to depreciation expense for
1994 of approximately $1.35 million.

                           KOPPERS INDUSTRIES, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 Accrued Insurance
 
  The Company is self-insured for property, casualty and workers' compensation
insurance up to various stop loss coverages. Losses are accrued based upon the
Company's estimates of the aggregate liability for claims incurred using
certain actuarial assumptions followed in the insurance industry and based on
Company experience.
 
 Research and Development
 
  Research and development costs, which are included in selling, general and
administrative expenses, amounted to $0.9 million for both 1994 and 1995, and
$1.0 million for 1996.
 
 Reclassification
 
  Certain amounts in the prior years' consolidated financial statements have
been reclassified to conform to the current year presentation. Such
reclassification had no effect on net income.
 
 Impact of Recently Issued Accounting Standards
 
  In March 1995 the Financial Accounting Standards Board issued Statement No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of," which requires impairment losses to be recorded on
long-lived assets used in operations when indicators of impairment are present
and the undiscounted cash flows estimated to be generated by those assets are
less than the assets' carrying amount. Statement 121 also addresses the
accounting for long-lived assets that are expected to be disposed of. The
Company adopted Statement 121 in the first quarter of 1996 and the effect of
adoption was not material.
 
2.RESTRUCTURING CHARGES
 
 
  The restructuring charges of $15.5 million for 1996 include $6.5 million for
the closing of a tar distillation facility in Houston, Texas; $0.9 million
related to the closing of a refractory materials facility in Carrollton, Ohio;
$5.4 million related to the idling of part of the coke operations at the
Company's Woodward, Alabama coke facility; and $2.6 million for severance
charges unrelated to the closing of these facilities; and $0.1 million for
other.
 
  The total restructuring charges consist of the following cash and non-cash
charges (in millions):
 
<TABLE>
<S>                                                                         <C>

   Dismantling and tank cleaning........................................... $3.6
   Severance............................................................... $3.3

  At December 31, 1996 approximately $0.5 million of the total cash charges
had been expended with the remainder to be expended in 1997.

  Results for 1994 included a $2.5 million expense related to a voluntary
severance plan initiated by the Company as part of a general corporate
restructuring. The total charge reflected salaries and benefits for 55
participating employees.
 
3.ACQUISITIONS
 
  In March 1995, the Company acquired a wood treating plant and certain assets
located in Somerville, Texas for $9.8 million. In April 1995, the Company
acquired a coke plant and certain assets located in Monessen, Pennsylvania for
$5 million. The Somerville plant began production in April 1995, and the
Monessen plant began production in November 1995. Both were accounted for as
purchases, and results of operations have been included since the dates of
acquisition. The pro forma effect of these acquisitions on the 1994 and 1995
results of the Company is not material.
 
  On April 1, 1996, the Company purchased a tar distillation plant and certain
assets located in Clairton, Pennsylvania for a cash purchase price of
approximately $40 million and the assumption of approximately $8 million of
liabilities, primarily for employee benefits, tank cleaning and dismantling of
idle equipment. The acquisition was accounted for as a purchase and,
accordingly, operating results of this business subsequent to the date of
acquisition are included in the Company's consolidated financial statements.
The excess purchase price over fair value of the net tangible assets acquired
was approximately $12 million and has been recorded as goodwill which is being
amortized on a straight-line basis over 25 years.
 
  The following table represents the pro forma results of the Company as if
the Clairton acquisition had taken place on January 1, 1995:

</TABLE>
 
  In March 1996 the Company's existing credit agreement with Mellon Bank,
N.A., as agent, along with a syndicate of other lenders, was amended (the
"Amended and Restated Credit Agreement") to increase the revolving credit
facility (the "Revolving Credit Facility") to $100 million from $75 million,
which includes letters of credit subject to an aggregate sublimit of $15
million. Proceeds from this facility were used to repay the remaining $10
million term loan which had originated in February 1994. A new term loan was
also established in the amount of $35 million for the purchase of the tar
distillation plant and certain other assets from Aristech Chemical Corporation
(the "Clairton Term Loan"), with repayments of $17.5 million due for both 2000
and 2001.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The Revolving Credit Facility provides for revolving credit loans up to $100
million, based upon a percentage of accounts receivable and inventory, until
March 18, 2001. Commitment fees ranging from 0.2% to 0.375% per annum on the
unborrowed amounts are required. The notes provide for interest at variable
rates. At December 31, 1996, the effective interest rate on the Revolving
Credit Facility was 6.9%, and the average rates during the years ended
December 31, 1995 and 1996 were 8.5% and 6.9%, respectively.
 
  In March 1995 the Company entered into a standby term loan agreement (as
amended in March 1996, the "Amended Somerville/Monessen Loan Agreement") to
finance the acquisitions and improvements of the Monessen coke plant and the
Somerville wood treating plant. The agreement provided for a $14 million term
loan for the Monessen plant and an $11 million term loan for the Somerville
plant. The balance on the loan requires repayments of $7 million in 1997, $9
million in 1998, and $5 million in 1999.
 
  The term loans under the Amended Somerville/Monessen Loan Agreement provide
for interest at variable rates. At December 31, 1996 the effective rate on the
term loans was 6.3%. The average rates on the term loans for the years ended
December 31, 1995 and 1996 were 9.3% and 6.8%, respectively.
 
  Substantially all of the Company's current assets (including accounts
receivable and inventories), as well as the fixed assets of Carbon Materials &
Chemicals, are pledged as collateral for the credit facilities established
under the Amended and Restated Credit Agreement, the Amended
Somerville/Monessen Loan Agreement and the Clairton Term Loan (collectively,
the "Bank Credit Facilities").
 
  The Bank Credit Facilities contain certain covenants which limit capital
expenditures by the Company and restrict its ability to incur additional
indebtedness, create liens on its assets, enter into leases, and make
investments or acquisitions. In addition, such covenants give rise to events
of default upon the failure by the Company to meet certain financial ratios.
While in the past the Company has been able to obtain waivers from these
covenants to complete acquisitions and consents to exclude certain items from
the calculation of such ratios in order to avoid such events of default, there
can be no assurance that such waivers or consents will be obtained in the
future and therefore these restrictive covenants may limit the ability of the
Company to expand through acquisitions and may give rise to events of default
on the Bank Credit Facilities and adversely affect the Company's liquidity.
 
  On February 10, 1994 the Company issued $110 million of 8.5% Senior Notes
maturing in 2004, with semiannual interest payments to the Note holders due
every February 1 and August 1.
 
  At December 31, 1996 the aggregate debt maturities for the next five years
are as follows:
 
<TABLE>
<S>                                                                  <C>

2001................................................................  60,500,000
</TABLE>
 
  The prepayment of debt on February 10, 1994 resulted in an extraordinary
loss of $1.8 million on a net-of-tax basis, comprised of write-offs of $1.9
million of original issue discount and $1.5 million of deferred financing
costs, net of a reduction of $1.6 million in put warrant liability. Deferred
financing costs associated with the refinancing totaled $5.3 million and are
being amortized over the life of the related debt.
 
  Deferred financing costs (net of accumulated amortization of $0.8 million at
December 31, 1994, $1.6 million at December 31, 1995 and $2.4 million at
December 31, 1996) were $4.8 million, $4.3 million and $4.4 million, at
December 31, 1994, 1995 and 1996, respectively, and are included in other
assets.
 
  At December 31, 1996, the Company had $8.5 million of standby letters of
credit outstanding, with terms ranging from one to two years.

5.STOCK ACTIVITY
 
  In March 1996, Cornerstone-Spectrum, Inc. exercised its option to convert
all of the Series B Convertible Preferred Stock into 2,340,000 shares of non-
voting common stock of the Company. Subsequent to the exercise, the Company
purchased and retired 1,050,000 shares of non-voting common stock of the
Company in equal amounts from Cornerstone-Spectrum, Inc. and APT Holdings
Corporation, a wholly owned subsidiary of Mellon Bank Corporation, the parent
of Mellon Bank, N.A. The effect of the purchase on stockholders' equity was to
decrease retained earnings and capital in excess of par value by $1.9 million
and $10.3 million, respectively.
 
  Warrants held by lenders to purchase 2,399,850 shares of non-voting common
stock in connection with previous debt financings of the Company were
exercised during 1995 for $1.11 each. The Company repurchased and retired
61,650 of these shares for $0.4 million. The effect of the exercise of the
remaining 2,338,200 warrants resulted in a reduction to put warrant liability
of $2.6 million and a reduction in equity warrants of $0.9 million. Total
stockholders' equity was increased by $5.2 million as a result of the exercise
of warrants. There were no warrants outstanding at December 31, 1996.
 
  All outstanding Series A preferred shares were redeemed in the amount of
$53.5 million in February 1994 by the Company, using a portion of the proceeds
from the Refinancing. In 1994 prior to the redemption the Company accrued
additional Series A dividends of $0.9 million.
 
  In prior years the Company recorded payments to a subsidiary Koppers
Australia KAP Investments, Inc. ("KAP") as the Series A Exchangeable Preferred
Stock held by KAP as paid-in-kind dividends. A portion of these payments
represented an additional investment by the Company in KAP, as opposed to a
dividend which would have been eliminated under equity accounting.
Accordingly, in connection with the redemption of the Series A Exchangeable
Preferred Stock in February 1994, the investment in KAP was increased by $3.75
million, with a related increase to retained earnings. The effect on earnings
available to common stock and earnings per common share over the period from
1988 through the redemption date in 1994 is not material in any individual
year.
 
  Treasury stock includes 1,125,000 shares held by KAP to reflect the
Company's 50% equity interest therein.
 
6.COMMON STOCK SUBJECT TO REDEMPTION
 
  The Company has a Stockholders' Agreement (the "Stockholders' Agreement") in
place which requires the Company, subject to cash payment limitations under
the terms of existing debt covenants, to redeem certain shares of common stock
owned by members of management upon a "termination event" relative to a
management employee. A termination event is defined as retirement, death,
disability, termination or resignation. At December 31, 1995 and 1996 the
maximum redemptions which would have been required under the Stockholders'
Agreement were $23.7 million and $24.0 million, respectively. The value of
shares subject to redemption under the terms of the Stockholders' Agreement is
segregated from other common stock on the face of the balance sheet. There
were approximately 2.0 million and 1.7 million shares of voting common stock
at December 31, 1995 and 1996, respectively, subject to the provisions of this
Stockholders' Agreement. The Stockholders' Agreement expires on December 28,
1998, or upon an initial public offering (IPO) of common stock in which more
than 35% of the post-IPO voting common stock is sold, whichever is earlier.
 
  The aggregate redemption amounts under the Agreement for the next three
years based on termination events which have already occurred are as follows:

  In determining the projected benefit obligation for funded status purposes,
discount rates of 7.25% and 7.5% were used for December 31, 1995 and 1996,
respectively. In 1995 and 1996, the assumed increase in future compensation
was 4% for salaried employees and 3.5% for hourly employees. The long-term
rate of return on plan assets is assumed to be 9% annually. Plan assets
consist of common stock, fixed income securities and short-term investments.
The Company funds the plans currently based on ERISA requirements. The change
in the discount rate in 1996 decreased the accumulated benefit obligation by
approximately $1.4 million. The net increase in the accumulated benefit
obligation reflects the additional liabilities assumed by the Company as the
result of acquisitions.
 
 Postretirement Benefits
 
  The Company sponsors a defined postretirement benefit plan to provide
medical and life insurance benefits to employees who retire after attaining
the required years of service with the Company, including their spouses.
Medical benefits are provided through a comprehensive indemnity plan and
community-rated health maintenance organizations.

  Currently, the Company pays a portion of the cost of such plans, but
reserves the right to modify cost-sharing provisions in the future. Life
insurance benefits are based primarily on the employee's compensation and are
also partially paid for by retiree contributions, which vary based upon
coverage chosen by the retiree.
 
  In determining the accumulated postretirement benefit obligation at December
31, 1995 and 1996, the Company used discount rates of 7.25% and 7.5%,
respectively. Inflation factors for the different types of medical costs were
assumed to range from 8.0% to 10.6% for 1997 and to decrease gradually to 6.7%
per year within 11 years.
 
  The following summarizes the Company's accrued obligation:

and options were exercised with proceeds used to repurchase shares of common
stock at average market value. Shares held by KAP have been reduced to reflect
the Company's 50% ownership interest therein.
 
  For purposes of determining earnings per share, all Series B Junior
Convertible Preferred Stock is assumed to have been converted into non-voting
Common Stock.

10.STOCK OPTIONS
 
  The Company grants stock options for a fixed number of shares to employees
with an exercise price equal to the fair value of the shares at the date of
grant. The Company accounts for stock option grants in accordance with
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" and, accordingly, recognizes no compensation expense for stock
option grants.

  The pro forma effect on net income and earnings per share for 1995 and 1996
of the fair value method required by Statement No. 123, "Accounting for Stock-
Based Compensation" is immaterial. The fair value for these options was
estimated at the date of grant using a Black-Scholes option pricing model with
the following weighted-average assumptions for 1995 and 1996: risk-free
interest rate of 6%; dividend yield of 2.7%; volatility factor of .18; and an
expected life of the option of 10 years.
 
  As of December 31, 1996, the Company's Board of Directors has awarded
options to purchase a total of 802,800 shares of Voting Common Stock to
certain key executives, at various exercise prices. All options granted have
10 year terms and vest and become fully exercisable at the end of three years
of continued employment.

11. COMMITMENTS AND CONTINGENCIES
 
 Environmental Indemnity and Guarantee
 
  The facilities of the Company are subject to a number of federal, state and
local laws and regulations governing, among other things, 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.
These laws and regulations are subject to frequent amendment. The Company
expects to incur substantial costs for ongoing compliance with such laws and
regulations. In addition, it is possible that the Company may face third-party
claims for cleanup or for injuries resulting from contamination. Under the
terms of the asset purchase agreement among the management investors, Beazer,
Inc. and Koppers Australia at the formation of the Company in 1988 (the "Asset
Purchase Agreement") Beazer East, Inc. ("Beazer East") assumed the liability
for and indemnified the Company against cleanup liabilities for past
contamination occurring prior to the purchase date at properties acquired from
Beazer East, as well as third-party claims arising from such past
contamination (the "Indemnity"). Beazer Limited unconditionally guaranteed
Beazer East's performance of the indemnity pursuant to a guarantee (the
"Guarantee"). However, if such indemnification was not available for any
reason, including the inability of Beazer East and/or Beazer Limited to make
such indemnification payments, the Company may not have sufficient resources
to meet such liabilities.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  Beazer East has adhered to the terms of the indemnity agreement and is
actively fulfilling its obligations to conduct investigative and remedial
programs at the properties which the Company acquired from Beazer East in
accordance with the requirements of regulatory authorities. The Indemnity is
not applicable to sites acquired since the formation of the Company, for which
separate indemnifications have been negotiated where appropriate. At the
properties which the Company acquired subsequent to the acquisition of the
Beazer East properties, all remedial actions are being performed in accordance
with applicable regulations and all indemnification obligations are being
honored.
 
  Beazer East and Beazer Limited are indirect subsidiaries of Hanson PLC. The
largest and smallest group in which the results of these companies are
consolidated is that headed by Hanson PLC. Beazer East is an operating company
which had revenues of approximately $600 million for each of the last three
fiscal years ended September 28, 1996 and had total assets of $1.7 billion as
of September 28, 1996. The Beazer East unaudited consolidated balance sheet at
September 28, 1996 reflects negative net worth of $64 million (including an
intercompany liability of $1.4 billion). This negative net worth is in large
measure the result of the adoption of SFAS 121 which resulted in pre-tax
charges for asset write downs of $4.4 billion during fiscal year 1996.
Furthermore, Beazer East had a negative cash flow from operations in the
fiscal year ended September 28, 1996 and required funding from other Hanson
subsidiaries to meet its obligations. According to the Directors' Report and
draft accounts for the year ended September 30, 1996 Beazer Limited is a
holding company. While the balance sheet at September 30, 1996 expects to show
a negative shareholder funds balance of (Pounds)10.4bn, the accounts are
prepared under the going concern concept because a fellow subsidiary
undertaking provides financial support to enable Beazer Limited to meets its
liabilities as they fall due. The Company has been informed that Beazer East
and Beazer Limited will remain wholly-owned indirect subsidiaries of Hanson
PLC. Management believes that Beazer East and Beazer Limited will continue to
fulfill their obligations as they have for the last 8 years.
 
  In the event that Beazer East and Beazer Limited do not continue to fulfill
their commitment under the Indemnity and the Guarantee, the Company may be
required to pay costs covered by the Indemnity. The Company has been informed
by Beazer East that for the last three years amounts paid by Beazer East under
the Indemnity have averaged approximately $13 million per year. The
requirement to pay such costs without reimbursement would have a material
adverse effect on the business, financial condition and results of operations
of the Company. Furthermore, if the Company were required to record a
contingent liability in respect of matters covered by the Indemnity on its
balance sheet the result could be that the Company would have significant
negative net worth.
 
  In addition, Beazer East is presently defending certain toxic tort actions
arising from the pre-Closing operation of assets which the Company acquired
from Beazer East. These tort actions were not assumed by the Company under the
Asset Purchase Agreement and, in any event, are within the scope of the
Indemnity.
 
 Other Environmental Matters
 
  The Jefferson County Department of Health ("Jefferson County") issued a
notice of violation in March 1996 in connection with various alleged
violations of Jefferson County's air pollution control regulations for
emissions from coke oven batteries at the Company's Woodward, Alabama coke
facility (the "Woodward Facility") during the period May 26, 1992 through
March 1, 1996. The Company and Jefferson County are currently negotiating a
settlement agreement, pursuant to which the Company might be required to
install monitoring and control equipment and institute operational changes.
The present draft of the settlement agreement also proposes that the Company
pay a civil penalty in the amount of $300,000, although the Company has not
agreed to such amount. In addition, the Company has decided that it will
permanently shut down Batteries No. 4A and No. 4B and idle one-half of Battery
No. 5 at the Woodward Facility, resulting in a loss of

approximately one-third of the production capacity. Recently, the United
States Environmental Protection Agency ("EPA") sent a notice of violation to
the Company covering the same issues that are being addressed in the
settlement agreement negotiations. There can be no assurance that the
resolution of this matter, including additional actions or penalties that
might be required by the EPA, if any, will not have a material adverse effect
on the business, financial condition and results of operations of the Company.
 
  The Company recently discovered that certain benzene abatement equipment at
the Company's Woodward Facility has not been operational for several months.
Following a preliminary investigation the Company also discovered that certain
reports and records contained incomplete and inaccurate information and that
certain reports and certifications were not filed when required. The Company
has notified Jefferson County, the State of Alabama and the EPA of the
environmental irregularities. Counsel and independent investigators have been
retained to conduct a complete and thorough investigation. While the Company
believes that the costs to repair such equipment will not exceed $300,000, the
Company could be subject to significant liability in connection with these
matters, including fines and civil and criminal penalties and the risk of
third party litigation and there can be no assurances that the resolution of
these matters will not have a material adverse effect on the business,
financial condition and results of operations of the Company.
 
  The Pennsylvania Department of Environmental Protection ("PADEP") recently
issued a notice of violation alleging that the boilers at the Monessen
Facility are emitting greater quantities of nitrogen oxides than allowed under
a plan approved by PADEP. The Company is currently installing additional
equipment, modifying existing equipment and investigating additional methods
to improve boiler performance. If these measures are not successful, the
Company may have to install post-combustion control equipment. Resolution of
the matter could have a negative effect on the business, financial condition
and results of operations of the Company.
 
 Litigation Settlements
 
  The Company settled litigation with CSX Transportation, Inc. ("CSX") related
to a Complaint served by CSX on May 24, 1996 which alleged that the Company
failed to fulfill environmental obligations under two contracts executed by
CSX and the Company's predecessor in 1988 and performed by the Company. The
Complaint also sought reimbursement of any damages incurred in connection with
a 1992 lawsuit filed by Beazer East against CSX in which Beazer East sought
contribution for environmental cleanup at certain facilities including some
presently owned by the Company. The settlement agreement requires the Company
to pay certain amounts in each of the next five years. The Company has
recorded a $2.5 million charge to pretax earnings in the fourth quarter of
1996 as a result of the agreement.
 
  On October 4, 1996 the Company settled litigation with Owens-Corning
Fiberglas Corporation ("OCF") which involved matters which occurred before the
Company came into existence. The case went to trial in early 1996 and, in
April 1996 resulted in a jury verdict against the Company for $10.3 million
plus legal fees and claims for pre-trial and post-trial interest. The Company
entered into a confidential settlement with OCF under which the Company paid
$12.7 million, in settlement of all claims. The charge to earnings for 1996
for the settlement and related legal fees was $10.2 million, as $3 million had
been provided for previously.
 
 Rents
 
  Rent expense for 1994, 1995 and 1996 was $10.3 million, $11.1 million and
$13.5 million, respectively. Commitments during the next five years under
operating leases approximate $14 million per year.

             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
(1) The Management's Discussion and Analysis of Financial Condition and
    Results of Operations ("MD&A") which is contained in this Prospectus
    contains additional information on the results of operations and the
    financial position of the Company. Those comments should be read in
    conjunction with these notes. The Company's audited financial statements
    for the years ended December 31, 1994, 1995, and 1996 include additional
    information about the Company, its operations, and its financial position,
    and should be read in conjunction with this quarterly financial
    information.
 
(2) The results for the interim periods are not necessarily indicative of the
    results to be expected for the full fiscal year.
 
(3) In the opinion of management, all adjustments (consisting of normal
    recurring accruals) considered necessary for a fair presentation have been
    included.
 
(4) On October 15, 1997 certain members of the group of management investors
    of the Company (the "Management Investors"), along with KAP Investments,
    Inc., ("KAP") a wholly-owned subsidiary of Koppers Australia Pty. Limited,
    the Company's 50% joint venture in Australia ("Koppers Australia")
    purchased 2,117,952 shares of voting Common Stock and 1,815,000 shares of
    non-voting common stock from Cornerstone-Spectrum, Inc. ("Cornerstone")
    for $52.5 million. The purchase of shares was an exercise of a right of
    first refusal granted to existing shareholders in the Company's
    stockholders' agreement which was part of the formation of the Company in
    1988 (the "Stockholders' Agreement"). As a result of the sale of shares by
    Cornerstone, and in accordance with the terms of the Stockholder'
    Agreement, the Cornerstone director, Brian C. Beazer, tendered his
    resignation from the Board of Directors of the Company. The Management
    Investors and Koppers Australia intend to use the shares to repay certain
    loans obtained to finance the transaction.
 
(5) On October 8, 1997 the Company announced that it had entered into a
    definitive agreement with the Broken Hill Proprietary Company Limited
    located in Melbourne, Australia ("Broken Hill") to acquire its 50%
    interest in Koppers Australia, which will result in Koppers Australia
    being a wholly-owned subsidiary of the Company. The purchase, with an
    estimated purchase price of $65 million, is expected to be completed in
    the fourth quarter of 1997.
 
(6) The Company has issued a cash tender offer and consent solicitation
    relating to all of the Company's $110 million 8 1/2% Senior Notes due 2004
    (the "Notes"). The tender offer is part of the Company's overall plan of
    recapitalization (the "Recapitalization"). At the expiration of the tender
    offer the remaining steps of the Recapitalization will be completed,

                        REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors of KOPPERS AUSTRALIA PTY. LIMITED
 
  We audited the accompanying consolidated balance sheets of Koppers Australia
Pty. Limited as of June 30, 1996 and June 30, 1997, and the related
consolidated statements of profit and loss and cash flows for the two years
ended June 30, 1997. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards in the 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 Australia Pty. Limited at June 30, 1996 and 1997 and the
consolidated results of their operations and their cash flows for the years
ended June 30, 1996 and 1997 in conformity with generally accepted accounting
principles in the United States.
 
  As discussed in Note 1 to the financial statements, in fiscal 1997, the
Company changed its method of accounting for investments in associates.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 a) Basis of accounting
 
  The financial statements are general purpose financial statements which have
been made out in accordance with the requirements of the Corporations Law
which include disclosures required by Schedule 5 and applicable Accounting
Standards and other mandatory professional reporting requirements (Urgent
Issues Group Consensus Views).
 
  The accounting policies adopted are consistent with those of the previous
year except as outlined below.
 
  In accordance with ASC Class Order 97/0798, the directors have elected to
adopt the provisions of Proposed Revised Accounting Standard AASB1016
Accounting for Investments in Associates. The effect is that investments in
associates are brought to account using the equity method of accounting under
which the carrying amount of the investment is increased or decreased to
recognise the investor's share of the post-acquisition profits or losses and
other changes in net assets of the associate. The investor's share of the
post-acquisition profits or losses of the associate is included in the
consolidated profit or loss account of the investor.
 
  Investments in associates were previously brought to account at cost. (Refer
Note 12)
 
 b) Foreign currencies
 
  Translation of foreign currency transactions
 
  Transactions in foreign currencies of entities within the economic entity
are converted to local currency at the rate of exchange ruling at the date of
the transaction.
 
  Amounts payable to and by the entities within the economic entity that are
outstanding at the balance date and are denominated in foreign currencies have
been converted to local currency using rates of exchange ruling at the end of
the financial year.
 
  Except for certain specific hedges and hedges of foreign currency
operations, all resulting exchange differences arising on settlement or
restatement are brought to account in determining the profit or loss for the
financial year, and transaction costs, premiums and discounts on forward
currency contracts are deferred and amortized over the life of the contract.
 
  Specific hedges
 
  Where a purchase or sale is specifically hedged, exchange gains or losses on
the hedging transaction arising up to the date of purchase or sale and costs,
premiums and discounts relative to the hedging transaction are included with
the purchase or sale. Exchange gains and losses arising on the hedge
transaction after that date are taken to the profit and loss account.
 
  Hedges of foreign operations
 
  Exchange gains and losses on transactions hedging investments in foreign
operations are taken to the foreign currency translation reserve on
consolidation.
 
  Translation of accounts of overseas operations
 
  All overseas operations are deemed self-sustaining as each is financially
and operationally independent of Koppers Australia Pty. Limited. The accounts
of overseas operations are translated using the current rate method and any
exchange differences are taken directly to the foreign currency translation
reserve.
 
 c) Cash
 
  For the purposes of the statement of cash flows, cash includes cash on hand
and in banks, and money market investments readily convertible to cash within
two working days, net of outstanding bank overdrafts.

 d) Inventories
 
  Inventories are valued at the lower of cost and net realisable value.
 
  Costs incurred in bringing each product to its present location and
condition are accounted for as follows:
 
  *  Raw materials--purchase cost on a first-in-first-out basis; and
 
  *  Finished goods and work-in-progress--cost of direct material and labour
     and a proportion of manufacturing overheads based on operating capacity.
 
 e) Recoverable amount
 
  Non-current assets are not revalued to an amount above their recoverable
amount, and where carrying values exceed this recoverable amount assets are
written down. In determining recoverable amount the expected net cash flows
have not been discounted to their present value.
 
 f) Property, plant and equipment
 
  Cost and valuation
 
  Items of property, plant and equipment comprising a class of non-current
assets are revalued at the same date on a consistent basis. Assets under
construction are brought to account at cost.
 
  Where assets have been revalued, the potential effect of the capital gains
tax on disposal has not been taken into account in the determination of the
revalued carrying amount.
 
  Depreciation
 
  Depreciation is provided on a straight line basis on all property, plant and
equipment, other than freehold land.
 
  Major depreciation periods are:

which benefits are expected to be received. This is taken as being 20 years.

  Significant items of carry forward expenditure having a benefit or
relationship to more than one period are written off over the periods to which

 Superannuation Commitments
 
  All employees are entitled to varying levels of benefits on retirement,
disability or death. The superannuation plan provides defined benefits based
on years of service and final average salary. Employees contribute to the
plans at various percentages of their wages and salaries. Up until the year
ended 30 June 1994, the economic entity did not contribute to the plan.
Commencing this year, the economic entity has contributed to the plan amounts
advised by the plan manager. These contributions are not of a systematic and
long-term nature as the plan has sufficient funds to satisfy all benefits
vested under the plan as at 30 June 1997.
 
  Details of the superannuation fund as extracted from the fund's most recent
annual report (31 August 1996) are as follows:

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Sections 1741 and 1742 of the BCL provide that a business corporation shall
have the power to indemnify any person who was or is a party, or is threatened
to be made a party, to any proceeding, whether civil, criminal, administrative
or investigative, by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation, or is or was servicing at the
request of the corporation as a director, officer, employee or agent of
another corporation or other enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably believed to be in, or not opposed to, the best interests of the
corporation, and, with respect to any criminal proceeding, had no reasonable
cause to believe his conduct was unlawful. In the case of an action by or in
the right of the corporation, such indemnification is limited to expenses
(including attorneys' fees) actually and reasonably incurred by such person in
connection with the defense or settlement of such action, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person has been adjudged to be liable to the corporation unless,
and only to the extent that, a court determines upon application that, despite
the adjudication of liability but in view of all the circumstances, such
person is fairly and reasonably entitled to indemnity for the expenses that
the court deems proper.
 
  BCL Section 1744 provides that, unless ordered by a court, any
indemnification referred to above shall be made by the corporation only as
authorized in the specific case upon a determination that indemnification is
proper in the circumstances because the indemnitee has met the applicable
standard of conduct. Such determination shall be made:
 
  (1) by the Board of Directors by a majority vote of a quorum consisting of
      directors who were not parties to the proceeding; or
 
  (2) if such a quorum is not obtainable, or if obtainable and a majority
      vote of a quorum of disinterested directors so directs, by independent
      legal counsel in a written opinion; or
 
  (3) by the shareholders.
 
  Notwithstanding of the above, BCL Section 1743 provides that to the extent
that a director, officer, employee or agent of a business corporation is
successful on the merits or otherwise in defense of any proceeding referred to
above, or in defense of any claim, issue or matter therein, such person shall
be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection therewith.
 
  BCL Section 1745 provides that expenses (including attorney's fees) incurred
by an officer, director, employee or agent of a business corporation in
defending any proceeding may be paid by the corporation in advance of the
final deposition of the proceeding upon receipt of an undertaking to repay the
amount advanced if it is ultimately determined that the indemnitee is not
entitled to be indemnified by the corporation.
 
  BCL Section 1746 provides that the indemnification and advancement of
expenses provided by, or granted pursuant to, the foregoing provisions are not
exclusive of any other rights to which a person seeking indemnification may be
entitled under any bylaw, agreement, vote of shareholders or directors or
otherwise, and that indemnification may be granted under any bylaw, agreement,
vote of shareholders or disinterested directors or otherwise for any action
taken or any failure to take any action whether or not the corporation would
have the power to indemnify the person under any other provision of law and
whether or not the indemnified liability arises or arose form any action by or
in the right of the corporation, provided, however, that no indemnification is
determined by a court to have constituted willful misconduct or recklessness.

  BCL Section 1747 permits a Pennsylvania business corporation to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of
the corporation as a director, officer, employee or agent of another
corporation or other enterprise, against any liability asserted against such
person and incurred by him in any such capacity, or arising out of his status
as such, whether or not the corporation would have the power to indemnify the
person against such liability under the provisions described above.
 
  The Registrant's Articles of Incorporation and Bylaws provide for (i)
indemnification of directors, officers, employees and agents of the registrant
and its subsidiaries and (ii) the elimination of a director's liability for
monetary damages, to the maximum extent permitted by the BCL. The Registrant
also maintains directors' and officers' liability insurance covering its
directors and officers with respect to liabilities, including liabilities
under the Securities Act of 1933, as amended, which they may incur in
connection with their serving as such.

     (i) Report of independent auditor on financial statement schedule.
 
     (ii) Schedule II
 
  All other schedules for which provision is made in the applicable accounting
regulations of the Securities and Exchange Commission are not required under
the related instructions or are inapplicable, and therefore have been omitted.
 
ITEM 22. UNDERTAKINGS.
 
  The Registrant hereby undertakes that
 
  (a) (1) For purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part of
this exchange offer in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this exchange offer as
of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new exchange offer relating to the securities offered
therein and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
  (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted for directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.

Dear Ladies and Gentlemen:


     We have examined a copy of the Registration Statement on Form S-4 (No. 
333-43153) (the "Registration Statement"), filed by Koppers Industries, Inc. 
(the "Company") with the Securities and Exchange Commission (the "Commission") 
on December 22, 1997, relating to the registration pursuant to the provisions of
the Securities Act of 1933, as amended (the "Act"), of up to $175,000,000 
principal amount of 9 7/8% Notes due 2007 (the "New Notes"). The New Notes, 
which upon the effectiveness of the Registration Statement will be registered 
under the Act, will be issued in exchange for a like principal amount of the 
Company's outstanding 9 7/8% Notes due 2007 (the "Old Notes"), which are not 
registered under the Act. The terms of the New Notes have been established 
pursuant to authorizing resolutions (the "Authorizing Resolutions") adopted by 
the Pricing Committee of the Board of Directors of the Company on November 19, 
1997, and are identical in all material respects to the Old Notes, except for 
certain transfer restrictions relating to the Old Notes. The New Notes will be 
issued pursuant to the Authorizing Resolutions and an Indenture (the 
"Indenture") dated as of December 1, 1997, between the Company and PNC Bank, 
National Association. In rendering this opinion, we have reviewed such documents
and made such investigations as we have deemed appropriate.


     Based on the foregoing, and subject to the qualifications stated herein, we
are of the opinion that:


     The New Notes have been duly authorized for issuance and, when duly 
executed, authenticated, registered, issued and delivered in exchange for Old 
Notes of a like principal amount, in accordance with the terms of the Indenture 
and the Authorizing Resolutions and as contemplated by the Registration 
Statement, will constitute valid and binding obligations of the Company, 
enforceable against the Company in accordance with their terms and entitled to 
the benefits of the Indenture and the Authorizing Resolutions, subject to 
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent 
conveyance and similar laws affecting creditors' rights and remedies generally 
and subject to general principles of equity.

     We are members of the bar of the Commonwealth of Pennsylvania and do not
purport to be experts in, or to express any opinion concerning, the laws of any
jurisdiction other than the law of the Commonwealth of Pennsylvania and the
federal laws of the United States of America.

     Neither this opinion nor any part hereof may be delivered to, used or

Koppers Industries, Inc.
436 Seventh Avenue
Pittsburgh, PA 15219

Ladies and Gentlemen:


     We have acted as counsel for Koppers Industries, Inc., a Pennsylvania 
corporation (the "Company"), in connection with the Registration Statement on 
Form S-4 (the "Registration Statement") filed by the Company with the Securities
and Exchange Commission (the "Commission") under the Securities Act of 1933, as 
amended (the "Securities Act"), relating to the issuance by the Company of 
$175,000,000 aggregate principal amount of its 9 7/8% Senior Subordinated Notes 
due 2007 (the "Exchange Notes"). The Exchange Notes are to be offered by the 
Company in exchange (the "Exchange") for $175,000,000 aggregate principal amount
of its outstanding 9 7/8% Senior Subordinated Notes due 2007 (the "Notes"). The 
Notes have been, and the Exchange Notes will be, issued under an Indenture dated
as of December 1, 1997 (the "Indenture") between the Company and PNC Bank, 
National Association as Trustee (the "Trustee").

     We have examined the Registration Statement and the Indenture which has 
been filed with the Commission as an Exhibit to the Registration Statement. In 
addition, we have examined, and have relied upon as to matters of fact, the 
originals or copies, certified or otherwise identified to our satisfaction, of 
such corporate records, agreements, documents and other instruments and such 
certificates or comparable documents of public officials and of officers and 
representatives of the Company, and have made such other and further 
investigations, as we have deemed relevant and necessary as a basis for the 
opinion hereinafter set forth.

     In such examination, we have assumed the genuineness of all signatures, the
legal capacity of natural persons, the authenticity of all documents submitted
to us as originals and the conformity to original documents of all documents
submitted to us as certified or photostatic copies, and the authenticity of the
originals of such latter documents.

     Based upon the foregoing, and subject to the qualifications and limitations
stated herein, we hereby confirm our opinion set forth in the Prospectus
included in the Registration Statement under the caption "Federal Income Tax
Consequences of Owning New Notes."

     We are members of the Bar of the Commonwealth of Pennsylvania and we do not
express any opinion herein concerning any law other than the Federal law of the
United States.

     We hereby consent to the use of this opinion as an Exhibit to the
Registration Statement and to the reference to our firm under the captions
"Federal Income Tax Consequences of Owning New Notes" and "Legal Matters" in the
prospectus included therein.

                                         
                                         Very truly yours,
                                         
                                         /s/ Dickie, McCamey & Chilcote, P.C.

  The undersigned acknowledges that he or she has received and reviewed the
Prospectus, dated January 23, 1998 (the "Prospectus"), of Koppers Industries,
Inc., a Pennsylvania corporation (the "Company"), and this Letter of
Transmittal (the "Letter") which together constitute the Company's offer (the
"Exchange Offer") to exchange up to $175,000,000 aggregate principal amount of
the Company's 9 7/8% Senior Subordinated Notes Due 2007 (the "New Notes"),
which have been registered under the Securities Act of 1933, as amended (the
"Securities Act"), for a like principal amount of the Company's issued and
outstanding 9 7/8% Senior Subordinated Notes Due 2007 (the "Old Notes"), which
have not been so registered.     
 
  For each Old Note accepted for exchange, the registered holder of such Old
Note (collectively with all other registered holders of Old Notes, the
"Holders") will receive a New Note having a principal amount equal to that of
the surrendered Old Note. Registered holders of New Notes on the relevant
record date for the first interest payment date following the consummation of
the Exchange Offer will receive interest accruing from the most recent date to
which interest has been paid on the Old Notes or, if no interest has been paid
on the Old Notes, from December 1, 1997. Old Notes accepted for exchange will
cease to accrue interest from and after the date of consummation of the
Exchange Offer. Accordingly, Holders whose Old Notes are accepted for exchange
will not receive any payment in respect of accrued interest on such Old Notes
otherwise payable on any interest payment date, the record date for which
occurs on or after consummation of the Exchange Offer.
 
  This Letter is to be completed by a Holder of Old Notes either if
certificates are to be forwarded herewith or if a tender of certificates for
Old Notes, if available, is to be made by book-entry transfer to the account
maintained by the Exchange Agent at The Depository Trust Company (the "Book-
Entry Transfer Facility") pursuant to the procedures set forth in "The
Exchange Offer--Book-Entry Transfer" section of the Prospectus and an Agent's
Message (as defined herein) is not delivered. Holders of Old Notes whose
certificates are not immediately available, or who are unable to deliver their
certificates or confirmation of the book-entry tender of their Old Notes into
the Exchange Agent's account at the Book-Entry Transfer Facility (a "Book-
Entry Confirmation") and all other documents required by this Letter to the
Exchange Agent on or prior to the Expiration Date, must tender their Old Notes
according to the guaranteed delivery procedures set forth in "The Exchange
Offer--Guaranteed Delivery Prospectus" section of the Prospectus. See
Instruction 1. Delivery of documents to the Book-Entry Transfer Facility does
not constitute delivery to the Exchange Agent.
 
   THE UNDERSIGNED HAS COMPLETED THE APPROPRIATE BOXES BELOW AND SIGNED THIS
 LETTER TO INDICATE THE ACTION THE UNDERSIGNED DESIRES TO TAKE WITH RESPECT TO
                              THE EXCHANGE OFFER.
 
<PAGE>
 
              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY
 
Ladies and Gentlemen:
 
  Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the aggregate principal amount of
Old Notes indicated below. Subject to, and effective upon, the acceptance for
exchange of the Old Notes tendered hereby, the undersigned hereby sells,
assigns and transfers to, or upon the order of, the Company all right, title
and interest in and to such Old Notes as are being tendered hereby.
 
  The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Old Notes
tendered hereby and that the Company will acquire good and unencumbered title
thereto, free and clear of all liens, restrictions, charges and encumbrances
and not subject to any adverse claim when the same are accepted by the
Company. The undersigned hereby further represents that any New Notes acquired
in exchange for Old Notes tendered hereby will have been acquired in the
ordinary course of business of the person receiving such New Notes, whether or
not such person is the undersigned, that neither the Holder of such Old Notes
nor any such other person has an arrangement or understanding with any person
to participate in the distribution of such New Notes and that neither the
Holder of such Old Notes nor any such other person is an "affiliate" (as
defined in Rule 405 under the Securities Act) of the Company.
 
  The undersigned also acknowledges that this Exchange Offer is being made in
reliance on interpretations by the staff of the Securities and Exchange
Commission (the "SEC"), as set forth in no-action letters issued to third
parties, that the New Notes issued pursuant to the Exchange Offer in exchange
for the Old Notes may be offered for resale, resold and otherwise transferred
by a Holder thereof (other than a Holder that is an "affiliate" of the Company
within the meaning of Rule 405 under the Securities Act) without compliance
with the registration and prospectus delivery provisions of the Securities
Act, provided that such New Notes are acquired in the ordinary course of such
Holder's business and such Holder has no arrangement with any person to
participate in a distribution of such New Notes. However, the SEC has not
considered the Exchange Offer in the context of a no-action letter and there
can be no assurance that the staff of the SEC would make a similar
determination with respect to the Exchange Offer as in other circumstances. If
the undersigned is not a broker-dealer, the undersigned represents that it is
not engaged in, and does not intend to engage in, a distribution of New Notes
and has no arrangement or understanding to participate in a distribution of
New Notes. If any Holder is an affiliate of the Company, is engaged in or
intends to engage in, or has any arrangement or understanding with any person
to participate in, a distribution of the New Notes to be acquired pursuant to
the Exchange Offer, such Holder could not rely on the applicable
interpretations of the staff of the SEC and must comply with the registration
and prospectus delivery requirements of the Securities Act in connection with
any resale transaction. If the undersigned is a broker-dealer that will
receive New Notes for its own account in exchange for Old Notes that were
acquired as a result of market-making activities or other trading activities,
it acknowledges that it will deliver a prospectus meeting the requirements of
the Securities Act in connection with any resale of such New Notes. However,
by so acknowledging and by delivering a prospectus, the undersigned will not
be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act.
 
  The undersigned will, upon request, execute and deliver any additional
documents deemed by the Company to be necessary or desirable to complete the
sale, assignment and transfer of the Old Notes tendered hereby. All authority
conferred or agreed to be conferred in this Letter and every obligation of the
undersigned hereunder shall be binding upon the successors, assigns, heirs,
executors, administrators, trustees in bankruptcy and legal representatives of
the undersigned and shall not be affected by, and shall survive, the death or
incapacity of the undesigned. This tender may be withdrawn only in accordance
with the procedures set forth in "The Exchange Offer--Withdrawal Rights"
section of the Prospectus.
 
  Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" herein, please issue the New Notes (and, if applicable,
substitute certificates representing Old Notes for any Old Notes not
exchanged) in the name of the undersigned or, in the case of a book-entry
delivery of Old Notes, please credit

exchanged) to the undersigned at the address shown in the box herein entitled

substantially in the form provided by the Company (by telegram, telex,
facsimile transmission, mail or hand delivery), setting forth the name and
address of the Holder of Old Notes and the amount of Old Notes tendered
stating that the tender is being made thereby and guaranteeing that within
three New York Stock Exchange ("NYSE") trading days after the date of
execution of the Notice of Guaranteed Delivery, the certificates for all
physically tendered Old Notes, in proper form for transfer, or a Book-Entry
Confirmation, as the case may be, and any other documents required by this

  The method of delivery of this Letter, the Old Notes and all other required

  If any tendered Old Notes are owned of record by two or more joint owners,
all of such owners must sign this Letter.

specified herein and tendered hereby, no endorsements of certificates or
separate bond powers are required. If however, the New Notes are to be issued,
or any untendered Old Notes are to be reissued, to a person other than the
Holder, then endorsements of any certificates transmitted hereby or separate
bond powers are required. Signatures on such certificate(s) must be guaranteed
by an Eligible Institution.
 
  If this Letter is signed by a person other than the Holder or Holders of any
certificate(s) specified herein, such certificate(s) must be endorsed

signatures on such certificate(s) must be guaranteed by an Eligible
Institution.

executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and, unless waived by the Company,
proper evidence satisfactory to the Company of their authority to so act must
be submitted.

evidencing Old Notes not exchanged are to be issued or sent, if different from
the name or address of the person signing this Letter. In the case of issuance
in a different name, the employer identification or social security number of
the person named must also be indicated. Holders tendering Old Notes by book-
entry transfer may request that Old Notes not exchanged be credited to such
account maintained at the Book-Entry Transfer Facility as such Holder may
designate hereon. If no such instructions are given, such Old Notes not
exchanged will be returned to the name and address of the person signing this
Letter.

  5. TRANSFER TAXES. The Company will pay all transfer taxes, if any,
applicable to the transfer of Old Notes to it or its order pursuant to the
Exchange Offer. If, however, New Notes and/or substitute Old Notes not
exchanged are to be delivered to, or are to be registered or issued in the
name of, any person other than the Holder of the Old Notes tendered hereby, or
if tendered Old Notes are registered in the name of any person other than the
person signing this Letter, or if a transfer tax is imposed for any reason
other than the transfer of Old Notes to the Company or its order pursuant to
the Exchange Offer, the amount of any such transfer taxes (whether imposed on
the Holder or any other persons) will be payable by the tendering Holder. If
satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted herewith, the amount of such transfer taxes will be billed to such
tendering Holder and the Exchange Agent will retain possession of an amount of
New Notes with a face amount equal to the amount of such transfer taxes due by
such tendering Holder pending receipt by the Exchange Agent of the amount of
such taxes.
 
  Except as provided in this Instruction 5, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes specified in this Letter.
 
  6. WAIVER OF CONDITIONS. The Company reserves the absolute right to waive
satisfaction of any or all conditions enumerated in the Prospectus.
 
  7. NO CONDITIONAL TENDERS. No alternative, conditional, irregular or
contingent tenders will be accepted. All tendering Holders of Old Notes, by
execution of this Letter, shall waive any right to receive notice of the
acceptance of their Old Notes for exchange.
 
  Although the Company intends to notify Holders of defects or irregularities
with respect to tenders of Old Notes, neither the Company, the Exchange Agent
nor any other person shall incur any liability for failure to give any such
notice.
 
  8. MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES. Any Holder whose Old
Notes have been mutilated, lost, stolen or destroyed should contact the
Exchange Agent at the address indicated above for further instructions.
 
  9. WITHDRAWAL OF TENDERS. Tenders of Old Notes may be withdrawn at any time
prior to 5:00 p.m., New York City time, on the Expiration Date.
 
  For a withdrawal of a tender of Old Notes to be effective, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth above prior to 5:00 p.m., New York City time,
on the Expiration Date. Any such notice of withdrawal must (i) specify the
name of the person having deposited the Old Notes to be withdrawn (the
"Depositor"), (ii) identify the Old Notes to be withdrawn (including the
certificate number or numbers and principal amount of such Old Notes), (iii)
be signed by the Holder in the same manner as the original signature on this
Letter (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the trustee under the Indenture
register the transfer of such Old Notes into the name of the person
withdrawing the tender and (iv) specify the name in which any such Old Notes
are to be registered, if different from that of the Depositor. All questions
as to the validity, form and eligibility (including time of receipt) of such
notices will be determined by the Company, whose determination shall be final
and binding on all parties. Any Old Notes so withdrawn will be deemed not to
have been validly tendered for exchange for purposes of the Exchange Offer.
Any Old Notes that have been tendered for exchange but which are not exchanged
for any reason will be returned to the Holder thereof without cost to such
Holder as soon as practicable after withdrawal, rejection of tender or
termination of the Exchange Offer. Properly withdrawn Old Notes may be
retendered by following the procedures described above at any time on or prior
to 5:00 p.m., New York City time, on the Expiration Date.

  11. INCORPORATION OF LETTER OF TRANSMITTAL. This Letter shall be deemed to

Book-Entry Transfer Facility's ATOP procedures by any Participant on behalf of

                           IMPORTANT TAX INFORMATION
 
  Under current federal income tax law, a holder of New Notes is required to
provide the Company (as payor) with such holder's correct taxpayer
identification number ("TIN") on Substitute Form W-9 or otherwise establish a
basis for exemption from backup withholding to prevent backup withholding on
any New Notes delivered pursuant to the Exchange Offer and any payments
received in respect of the New Notes. If a holder of New Notes is an
individual, the TIN is such holder's social security number. If the Company is
not provided with the correct taxpayer identification number, a holder of New
Notes may be subject to a $50 penalty imposed by the Internal Revenue Service.
Accordingly, each prospective holder of New Notes to be issued pursuant to
Special Issuance Instructions should complete the attached Substitute Form W-
9. The Substitute Form W-9 need not be completed if the box entitled "Special
Issuance Instructions" has not been completed.
 
  Certain holders of New Notes (including, among others, all corporations and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements. Exempt prospective holders of New Notes should
indicate their exempt status on Substitute Form W-9. A foreign individual may
qualify as an exempt recipient by submitting to the Company, through the
Exchange Agent, a properly completed Internal Revenue Service Form W-8 (which
the Exchange Agent will provide upon request) signed under penalty of perjury,
attesting to the holder's exempt status. See the Enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions.
 
  If backup withholding applies, the Company is required to withhold 31% of
any payment made to the holder of New Notes or other payee. Backup withholding
is not an additional federal income tax. Rather, the federal income tax
liability of persons subject to backup withholding will be reduced by the
amount of tax withheld. If withholding results in an overpayment of taxes, a
refund may be obtained from the Internal Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
  To prevent backup withholding on any New Notes delivered pursuant to the
Exchange Offer and any payments received in respect of the New Notes, each
prospective holder of New Notes to be issued pursuant to Special Issuance
Instructions should provide the Company, through the Exchange Agent, with
either: (i) such prospective holder's correct TIN by completing the form
below, certifying that the TIN provided on Substitute Form W-9 is correct (or
that such prospective holder is awaiting a TIN) and that (A) such prospective
holder has not been notified by the Internal Revenue Service that he or she is
subject to backup withholding as a result of a failure to report all interest
or dividends or (B) the Internal Revenue Service has notified such prospective
holder that he or she is no longer subject to backup withholding; or (ii) an
adequate basis for exemption.
 
WHAT NUMBER TO GIVE THE EXCHANGE AGENT
 
  The prospective holder of New Notes to be issued pursuant to Special
Issuance Instructions is required to give the Exchange Agent the TIN (e.g.,
social security number or employer identification number) of the prospective
record owner of the New Notes. If the New Notes will be held in more than one
name or are not held in the name of the actual owner, consult the enclosed
Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9 for additional guidance regarding which number to report.
