PROSPECTUS
 
                            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and not withdrawn prior to 5:00 p.m., New York City time, on         , 1998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may be withdrawn at any time prior to the Expiration Date.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."

  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."

                                understanding with any person to participate,

                                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.

                                neither the holder nor any such other person
                                has any arrangement or understanding with any

                                defined under Rule 405 of the Securities Act,

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

                                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
                                under its Subsidiary Guarantee are subordinated

                                Guarantor Senior Debt (as defined herein) to
                                substantially the same extent as the Notes are
                                subordinated to all existing and future Senior
                                Debt of the Company.

                                repurchase all or any part of each holder's
                                Notes at a repurchase price equal to 101% of

                                principal amount thereof, plus accrued and
                                unpaid interest to the repurchase date. There
                                can be no assurance that the Company will have
                                the financial resources necessary to purchase
                                the Notes upon a Change of Control or that such
                                repurchase will be permitted under the New
                                Credit Facilities. See "Description of Notes--
                                Covenants--Change of Control."
 
Certain Covenants.............  The Indenture will contain certain covenants
                                that, among other things, will limit the
                                ability of the Company and its subsidiaries to
                                incur additional indebtedness, pay dividends or
                                make other distributions, make investments,
                                dispose of assets, issue preferred stock of
                                subsidiaries, create certain liens securing
                                indebtedness, enter into sale and leaseback
                                transactions, enter into certain transactions
                                with affiliates, or enter into certain mergers
                                or consolidations or sell all or substantially
                                all of the Company's assets. See "Description
                                of Notes--Covenants."

- --------
(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
    "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 settlement of a legal judgment rendered against Koppers
    in connection with litigation brought against Koppers by Owens-Corning
    Fiberglas Corporation (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 $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, 1994, 1995
    and 1996, and for the nine months ended September 30, 1996 and 1997,
    respectively. Other income includes $3.0 million, $2.2 million and $3.2
    million of equity earnings in affiliates 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, respectively.
(3) Net income for 1994 includes loss on early extinguishment of debt of $1.8
    million.
(4) The Stockholders' Agreement (as defined herein) 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.
(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
    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. 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).

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, prospective
investors should consider carefully the following risk factors in evaluating
whether to tender their Old Notes for New Notes in the Exchange Offer.
 
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."

  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
<PAGE>
 
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".

(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

    the terms of covenants contained in its debt instruments, to redeem stock
    held by Management Investors upon termination of their employment with

(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).

 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.

  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.
 
 
                                      43
<PAGE>
 
  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.

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
 
                                      60
<PAGE>
 
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.
 
                                      61
<PAGE>
 
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

  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

                     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

subject to upward adjustment, which amount shall be increased by 50% of the
Company's cumulative consolidated net income on a quarterly basis plus 100% of
the proceeds from equity issuances; capital expenditures not to exceed $35
million annually plus up to 50% of the previous year's permitted capital
expenditures to the extent such amounts were not expended in such previous
year; ratio of total debt to consolidated EBITDA of 4.80 to 1.00 initially
decreasing to 3.50 to 1.00; interest coverage ratio of 2.25 to 1.00 initially
increasing to 3.00 to 1.00; consolidated debt service coverage ratio of 1.75
to 1.00 initially decreasing to 1.25 to 1.00 and consolidated current ratio at
the end of any fiscal year to be not less than 1.10 to 1.00.
 
  Events of Default. Events of Default under the New Credit Facilities include
non-payment of principal, interest, fees or other amounts when due; violation
of covenants; failure of any representation or warranty to be true in all
material respects; cross-default and cross-acceleration; Change in Control (as
defined in the New Credit Facilities); bankruptcy and insolvency events with
respect to the Company or a guarantor; material judgments; ERISA events; and
actual or asserted (by the Company or a guarantor) invalidity of any loan

                             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

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.

  "Consolidated Fixed Charge Ratio" means the ratio, on a pro forma basis, of
(i) the aggregate amount of EBITDA of any Person for the Reference Period
immediately prior to the Determination Date to (ii) the aggregate Consolidated
Fixed Charges of such Person during such Reference Period; provided that for
purposes of such computation, in calculating EBITDA and Consolidated Fixed

therefrom will be assumed to have occurred on the first day of the Reference
Period, (2) Asset Dispositions and

by the Notes and the Subsidiary Guarantees; (iii) Debt of Koppers Australia,

80% of accounts receivable (reduced as necessary to reflect the disposition of
any such accounts

Company's consolidated balance sheet for the immediately preceding fiscal
quarter for which financial statements are available; (v) Debt in respect of

Owned Subsidiary; (viii) Debt secured by Liens described in (x) and (xv) of
the definition of Permitted Liens in an aggregate amount not to exceed
$5,000,000 at any one time outstanding and refinancings thereof provided that
the amount of such Debt is not increased; (ix) Debt issued in exchange for, or
the proceeds of which are used to refinance, outstanding or committed Debt of
the Company or any of the Notes in an amount (or, if such new Debt, is issued
at a price less than the principal amount thereof, with an original issue
price) not to exceed the amount so exchanged or refinanced (plus accrued
interest, fees, expenses and other obligations related thereto), provided that
if the Debt to be exchanged or refinanced by its terms ranks subordinate in
right of payment to the Notes, (1) the Debt exchanged for, or the proceeds of
which are used to refinance, such Debt is also subordinate to the Notes (at
least to the extent and in the manner that the Debt to be exchanged or
refinanced is subordinate to the Notes) in right of payment to the Notes and
(2) no payments of principal of such Debt by way of sinking fund, mandatory
redemption, mandatory repurchase or otherwise (including defeasance) may be
made by the Company (including, without limitation, at the option of the
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
Debt pursuant to such provisions prior to the Company's repurchase of the
Notes required to be repurchased by the Company pursuant to the corresponding
provisions contained in the Indenture) at any time prior to the final
scheduled maturity date of the Notes; provided further, that (A) if any
scheduled mandatory principal payment of the Debt being exchanged for or
refinanced has a due date after December 1, 2007, the corresponding scheduled
mandatory payment of the Debt issued in exchange for, or to refinance such
Debt, will not have a due date on or prior to December 1, 2007, and (B) in no
event may Debt of the Company or a Subsidiary of the Company be refinanced by
means of Debt of any other Subsidiary of the Company pursuant to the covenant
described in this clause; (x) Debt under Currency Agreements and Interest Rate
Agreements; (xi) Debt of Hickson outstanding from time to time in an aggregate
principal amount not to exceed the Australian dollar-equivalent of $10,000,000
at the time such Debt is issued, to the extent such Debt could be incurred
pursuant to the following paragraph; (xii) Asset Dispositions in the form of
Receivables Transactions; (xiii) Guarantees of Debt under the New Credit
Facilities otherwise permitted under the Indenture; and (xiv) to the extent
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.
 
 Change of Control.
 
  Upon a Change of Control, each Holder of the Notes will have the right to
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
circumstances and relevant facts regarding such Change of Control (including
information with respect to pro forma historical income, cash flow and
capitalization after giving effect to such Change of Control); (3) the
repurchase date (which will be not earlier than 30 days or later than 60 days
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
purchased pursuant to a Change of Control Offer will be required to surrender
the Note, with the form entitled "Option of Holder to Elect Purchase" on the
reverse of the Note completed, to the paying agent at the address specified in
the notice prior to the close of business on the Repurchase Date; (7) that
holders will be entitled to withdraw their election if the paying agent
receives, not later than the close of business on the third Business Day (or
such shorter periods as may be required by applicable law) preceding the
Repurchase Date, a telegram, telex, facsimile transmission or letter setting
forth the name of the holder, the principal amount of Notes the holder
delivered for purchase, and a statement that such holder is withdrawing his
election to have such Notes purchased; and (8) that holders which elect to
have their Notes purchased only in part will be issued new Notes in a
principal amount equal to the unpurchased portion of the Notes surrendered.
 
  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
Trustee will promptly mail to the holders of Note so accepted payment in an
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
the Note surrendered. The Company will publicly announce the results of the
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

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

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)

(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
<PAGE>
 
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        , 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        , 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 on
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."

              FEDERAL INCOME TAX CONSEQUENCES OF OWNING NEW NOTES
 
U.S. HOLDERS
 
  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       199 , 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.

            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):

  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:

  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>

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:

 Incentive Plan
 
  The Company has established a Management Incentive Plan based on established
target award levels for each participant if certain Company performance and
individual goals are met. The charge to operating expense for this plan was
$2.2 million in 1994, $4.1 million in 1995, and $2.9 million in 1996. For
incentive related to 1995 and 1996 results, participating employees may elect
to receive up to 50% of their incentive compensation in voting common stock of
the Company.
 
 Employee Savings Plan

  The Company has an alternative minimum tax credit carryforward of
approximately $5 million. The credit has no expiration date.
 
9.EARNINGS PER SHARE
 
  Earnings per share have been computed on the basis of the average number of
common shares outstanding. Earnings per share assume that all granted warrants
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.

  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

interest rate of 6%; dividend yield of 2.7%; volatility factor of .18; and an
expected life of the option of 10 years.

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,
    including: (i) the acquisition by the Company of the 50% of Koppers
    Australia not owned by it; (ii) the repayment in full of the Company's
    existing bank credit facilities; and (iii) the redemption by the Company
    of a portion of the shares of Common Stock held by certain existing
    investors, including a portion of such shares held by the Management
    Investors. Financing for the Recapitalization will be provided by a new
    senior credit facility and by a contemporaneous offering of senior
    subordinated notes of the Company pursuant to Rule 144A.
 
(7) The Company's payment obligations under the 9 7/8% Senior Subordinated
    Notes Due 2007 (Senior Subordinated Notes) are fully and unconditionally
    guaranteed on a joint and several basis by Koppers Industries
    International Trade Corporation, Koppers Australia Pty. Ltd., Koppers
    Industries of Delaware, Inc. and Koppers Industries B.W., Inc.
    (collectively, the "Guarantor Subsidiaries"). The Senior Subordinated
    Notes have not been guaranteed by KHC Assurance, Inc., Tarconord A/S, and
    KSA Limited Partnership (collectively, the "Non-Guarantor Subsidiaries").
    In accordance with previous positions established by the Securities and
    Exchange Commission, the following summarized financial information
    illustrates separately the composition of the Guarantor Subsidiaries and
    the Non-Guarantor Subsidiaries. Separate complete financial statements of

                        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

                             30 JUNE 1996 AND 1997
 
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.

      NOTES TO AND FORMING PART OF THE FINANCIAL STATEMENTS--(CONTINUED)
 
 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:

                                       whichever is shorter.
</TABLE>
 
 g) Intangibles
 
  Goodwill
 
  Goodwill is amortised by the straight line method over the period during
which benefits are expected to be received. This is taken as being 20 years.
 
 h) Other non-current assets
 
  Expenditure carried forward
 
  Significant items of carry forward expenditure having a benefit or
relationship to more than one period are written off over the periods to which
such expenditure relates.

 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.

  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.

     4(B) of this Agreement.  No form of general solicitation or general
     advertising (as those terms are used in Regulation D under the Act) was
     used by the Company, any of the Subsidiary Guarantors or any of their
     representatives in connection with the offer and sale of any of the Notes
     or in connection with Exempt Resales, including, but not limited to,
     articles, notices or other communications published in any newspaper,
     magazine or similar medium or broadcast over television or radio, or any
     seminar or meeting whose attendees have been invited by any general
     solicitation or general advertising.

          (29) The execution and delivery of this Agreement, the other Operative
     Documents and the sale of the Notes, the Exchange Notes, and Subsidiary
     Guarantees to be purchased by the Eligible Purchasers will not involve any
     prohibited transaction within the meaning of Section 406(a) of ERISA or
     Section 4975(c)(1)(A)-(D) of the Code.  The representation made by the
     Company and each of the Subsidiary Guarantors in the preceding sentence is
     made in reliance upon and subject to the accuracy of, and compliance with,
     the representations and covenants made or deemed made by the Eligible
     Purchasers as set forth in the Offering Memorandum under the caption
     "Transfer Restrictions."

          (30) Each of the Preliminary Offering Memorandum and the Offering
     Memorandum, as of its date, and each amendment or supplement thereto, as of
     its date, contains the information specified in, and meets the requirements
     of, Rule 144A(d)(4) under the Act.

          (31) Since the date as of which information is given in the Offering
     Memorandum, except as otherwise expressly set forth therein, neither the
     Company nor any of its subsidiaries had any material liabilities or
     obligations, direct or contingent, that were not set forth in the Company's
     consolidated balance sheet as of September 30, 1997, or in the notes
     thereto.  Since the date as of which information is given in the Offering
     Memorandum and up to the Closing Date, except as otherwise expressly set
     forth in the Offering Memorandum, (a) none of the Company or its
     subsidiaries has (1) incurred any liabilities or obligations, direct or
     contingent, that are not in the ordinary course of business that would,
     either individually or in the aggregate, result in a Material Adverse
     Effect or (2) entered into any material transaction not in the ordinary
     course of business, (b) there has not been any
<PAGE>
 
                                      -21-

     event or development in respect of the business, development or financial
     condition of the Company or any of its subsidiaries that would, either
     individually or in the aggregate, result in a Material Adverse Effect, (c)
     there has been no dividend or distribution of any kind declared, paid, or
     made by either the Company or any of its subsidiaries on any class of its
     capital stock, and (d) there has not been any change in the long-term debt
     of the Company and its subsidiaries.

          (32) Neither the Company nor any of its subsidiaries (nor any agent
     acting on behalf of the Company or any of the Subsidiary Guarantors) has
     taken, and none of them will take, any action that might cause this
     Agreement or the issuance or sale of the Notes or Exchange Notes to violate
     Regulation G (12 C.F.R. Part 207), Regulation T (12 C.F.R. Part 220),
     Regulation U (12 C.F.R. Part 221) or Regulation X (12 C.F.R. Part 224) of
     the Board of Governors of the Federal Reserve System or analogous foreign
     laws and regulations, in each case as in effect, or as the same may
     hereafter be in effect, on the Closing Date.

          (33) The accountants who have certified the financial statements
     included as part of the Offering Memorandum are independent accountants
     within the meaning of the Act.  The historical financial statements of the
     Company comply as to form in all material respects with the requirements
     applicable to registration statements on Form S-1 under the Act and present
     fairly in all material respects the consolidated financial position and
     results of operations of the Company at the respective dates and for the
     respective periods indicated.  Such financial statements have been prepared
     in accordance with United States generally accepted accounting principles
     applied on a consistent basis throughout the periods presented (except as
     disclosed in the Offering Memorandum) and comply as to form with the rules
     and regulations promulgated under the Act.  The historical financial
     statements of Koppers Australia present fairly in all material respects the
     consolidated financial position and results of operations of Koppers
     Australia at the respective dates and for the respective periods indicated.
     Such financial statements have been prepared in accordance with United
     States generally accepted accounting principles applied on a consistent
     basis throughout the periods presented (except as disclosed in the Offering
     Memorandum) and comply as to form with the rules and regulations

                                      -22-

     prepared on a basis consistent with such historical statements, except for
     the pro forma adjustments specified therein, (ii) include all material
         --- -----                                                         
     adjustments to the historical financial statements required by Rule 11-02
     of Regulation S-X under the Exchange Act to reflect the transactions
     described in the Offering Memorandum and (iii) give effect to assumptions
     made on a reasonable basis and present fairly in all material respects the
     historical and proposed transactions contemplated by the Offering
     Memorandum, this Agreement, the Operative Documents and the other
     Transaction Documents.  All other financial and statistical information and
     data included in the Offering Memorandum (including, but not limited to,
     financial and statistical information contained in the Offering Memorandum
     under the headings "Offering Memorandum Summary -- Summary Historical and
     Pro Forma Consolidated Financial Information," "Capitalization," "Selected
     Historical Consolidated Financial Information" and "Management's Discussion
     and Analysis of Financial Condition and Results of Operations"), historical
     and pro forma, are accurately presented in all material respects and
         --- -----                                                       
     prepared on a basis consistent with the financial statements and the books
     and records of the Company and its subsidiaries.

          (34) None of the Company or the Subsidiary Guarantors is or, upon
     consummation of the Transactions, will be (A) "insolvent" as that term is
     defined in Section 101(32) of the United States Bankruptcy Code (the
                                                                         
     "Bankruptcy Code") (11 U.S.C. (S) 101(32)), Section 2 of the Uniform
     ----------------                                                    
     Fraudulent Transfer Act ("UFTA") or Section 2 of the Uniform Fraudulent
                               ----                                         
     Conveyance Act ("UFCA"), (B) an entity with "unreasonably small capital" as
                      ----                                                      
     that term is used in Section 548(a)(2)(ii) of the Bankruptcy Code or
     Section 5 of the UFCA, (C) engaged or about to engage in a business or
     transaction for which its remaining property is "unreasonably small" in
     relation to the business or transaction as that term is used in Section 4
     of the UFTA or (D) unable to pay its debts as they mature or become due,
     within the meaning of Section 548(a)(2)(B)(iii) of the Bankruptcy Code,
     Section 4 of the UFTA and Section 6 of the UFCA.  The Company and each of
     the Subsidiary Guarantors now owns and upon consummation of the
     Transactions will own assets having a value both at "fair valuation" and at
     "present fair saleable value" greater than the amount required to pay its
     "debts" as such terms are used in Section 2 of the UFTA and Section 2 of
     the UFCA.

          (35) Koppers Australia is not insolvent (within the meaning of section
     95A of the Australian Corporations Law)
<PAGE>
 
                                      -23-

     as at the date of this Agreement and there are reasonable grounds to expect
     that immediately following consummation of the transactions contemplated by
     this Agreement, and each other Transaction Document to which Koppers
     Australia is a party, Koppers Australia will not become insolvent.

          (36) Except as described in the section entitled "Certain
     Relationships and Related Transactions" in the Offering Memorandum, there
     are no contracts, agreements or understandings between the Company or any
     of the Subsidiary Guarantors and any other person other than the Initial
     Purchaser that would give rise to a valid claim against the Company, the
     Subsidiary Guarantors or the Initial Purchaser for a brokerage commission,
     finder's fee or like payment in connection with the issuance, purchase and
     sale of the Notes or Exchange Notes.

          (37) The statistical and market-related data included in the Offering
     Memorandum are based on or derived from sources that the Company and the
     Subsidiary Guarantors believe to be reliable and accurate and represent the
     Company's and the Subsidiary Guarantors' good faith estimates that are made
     on the basis of data derived from such sources.

          (38) No forward-looking statement (within the meaning of Section 27A
     of the Act and Section 21E of the Exchange Act) contained in the Offering
     Memorandum has been made or reaffirmed without a reasonable basis or has
     been disclosed other than in good faith.

          (39) There are no securities of the Company or any of the Subsidiary
     Guarantors registered under the Exchange Act, or listed on a national
     securities exchange or quoted in a U.S. automated interdealer quotation
     system, other than the 8 1/2s.

          (40) The Company shall cause Koppers Australia and each of the
     Australian Subsidiary Guarantors to sign this Agreement on or before the
     Closing Date.

          (41) Each certificate signed by any officer of the Company or any of
     the Subsidiary Guarantors and delivered to the Initial Purchaser or counsel
     for the Initial Purchaser pursuant to, or in connection with, this
     Agreement shall be deemed to be a representation and warranty by the
     Company or such Subsidiary Guarantor to the Initial Purchaser as to the
     matters covered by such certificate.
<PAGE>
 
                                      -24-

          The Company and each of the Subsidiary Guarantors acknowledges that
the Initial Purchaser and, for purposes of the opinions to be delivered to the
Initial Purchaser pursuant to Section 7 of this Agreement, the various law firms
acting as counsel to the Company and each of the Subsidiary Guarantors and
counsel to the Initial Purchaser will rely upon the accuracy and truth of the
foregoing representations and the Company and each Subsidiary Guarantor hereby
consents to such reliance.

          (B)  The Initial Purchaser represents, warrants and covenants to the
Company that it is a QIB with such knowledge and experience in financial and
business matters as are necessary in order to evaluate the merits and risks of
an investment in the securities.  The Initial Purchaser represents, warrants and
agrees with the Company that (i) it has not and will not solicit offers for, or
offer or sell, the Notes by any form of general solicitation or general
advertising (as those terms are used in Regulation D under the Act) or in any
manner involving a public offering within the meaning of Section 4(2) of the Act
and (ii) it has and will solicit offers for the Notes only from, and will offer
the Notes only to, (x) persons whom the Initial Purchaser reasonably believes to
be QIBs or, if any such person is buying for one or more institutional accounts
for which such person is acting as fiduciary or agent, only when such person has
represented to the Initial Purchaser that each such account is a QIB to whom
notice has been given that such sale or delivery is being made in reliance on
Rule 144A, and, in each case, in transactions under Rule 144A, or (y) persons
other than U.S. persons outside the U.S. in reliance on Regulation S.

          The Initial Purchaser represents and warrants that the source of funds
being used by it to acquire the Notes does not include the assets of any
"employee benefit plan" (within the meaning of Section 3 of ERISA) or any "plan"
(within the meaning of Section 4975 of the Code).

          The Initial Purchaser understands that the Company and, for purposes
of the opinion to be delivered to them pursuant to Section 7(f) hereof, counsel
to the Company will rely upon the accuracy and truth of the foregoing
representations, and the Initial Purchaser hereby consents to such reliance.

          5.   INDEMNIFICATION.  (a)  Each of the Company and the Subsidiary
Guarantors, on a joint and several basis, agrees to indemnify and hold harmless
the Initial Purchaser, each person, if any, who controls the Initial Purchaser
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act,
the agents, employees, officers and directors of the Initial
<PAGE>
 
                                      -25-

Purchaser and the agents, employees, officers and directors of any such
controlling person from and against any and all losses, liabilities, claims,
damages and expenses whatsoever (including but not limited to reasonable
attorneys' fees and any and all reasonable expenses whatsoever incurred in
investigating, preparing or defending against any litigation, commenced or
threatened, or any claim whatsoever, and any and all reasonable amounts paid in
settlement of any claim or litigation) to which they or any of them may become
subject under the Act, the Exchange Act or otherwise insofar as such losses,
liabilities, claims, damages or expenses (or actions in respect thereof) arise
out of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the Preliminary Offering Memorandum or the Offering
Memorandum, or in any supplement thereto or amendment thereof, or arise out of
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading;
                                                                             
provided, however, that the Company and the Subsidiary Guarantors will not be
- --------  -------                                                            
liable in any such case to the extent, but only to the extent, that any such
loss, liability, claim, damage or expense arises out of or is based upon any
such untrue statement or alleged untrue statement or omission or alleged
omission made therein in reliance upon and in conformity with written
information relating to the Initial Purchaser furnished to the Company by the
Initial Purchaser expressly for use therein.  This indemnity agreement will be
in addition to any liability that each of the Company and the Subsidiary
Guarantors may otherwise have, including, but not limited to, liability under
this Agreement.

          If any action is brought against the Initial Purchaser or any such
person in respect of which indemnity may be sought against the Company and the
Subsidiary Guarantors pursuant to the foregoing paragraph, the Initial Purchaser
or such person shall promptly notify the indemnifying party in writing of the
institution of such action and the indemnifying party shall assume the defense
of such action, including the employment of counsel reasonably satisfactory to
such indemnified party and payment of all fees and expenses, provided, however,
that the omission to so notify the indemnifying party shall not relieve the
indemnifying party from any liability which they may have to the Initial
Purchaser or any such person or otherwise.  The Initial Purchaser shall have the
right to employ its own counsel in any such case, but the fees and expenses of
such counsel shall be at the expense of the Initial Purchaser unless the
employment of such counsel shall have been authorized in writing by the
indemnifying party in connection with the defense of such action
<PAGE>
 
                                      -26-

or the indemnifying party shall not have employed counsel to have charge of the
defense of such action or such indemnified party or parties shall have
reasonably concluded that there may be defenses available to it or them which
are different from or additional to those available to the indemnifying party
(in which case the indemnifying party shall not have the right to direct the
defense of such action on behalf of the indemnified party or parties), in any of
which events such fees and expenses shall be borne by the indemnifying party and
paid as incurred (it being understood, however, that the indemnifying party
shall not be liable for the expenses of more than one separate counsel (together
with appropriate local counsel) in any one action or series of related actions
in the same jurisdiction representing the indemnified parties who are parties to
such action).  The indemnifying party shall not be liable for any settlement of
any such claim or action effected without its written consent but if settled
with the written consent of the indemnifying party, the indemnifying party
agrees to indemnify and hold harmless the Initial Purchaser and any such person
from and against any loss or liability by reason of such settlement.
Notwithstanding the foregoing sentence, if at any time an indemnified party
shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel as contemplated by the second sentence of this
paragraph, then the indemnifying party agrees that it shall be liable for any
settlement of any proceeding effected without its written consent if (i) such
settlement is entered into more than 60 business days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall
not have reimbursed the indemnified party in accordance with such request prior
to the date of such settlement and (iii) such indemnified party shall have given
the indemnifying party at least 30 days' prior notice of its intention to
settle.  No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened proceeding
in respect of which any indemnified party is or could have been a party and
indemnity could have been sought hereunder by such indemnified party, unless
such settlement includes an unconditional release of such indemnified party from
all liability on claims that are the subject matter of such proceeding.

          (b) The Initial Purchaser agrees to indemnify and hold harmless the
Company and the Subsidiary Guarantors, each person, if any, who controls the
Company within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, and each of its agents, employees, officers and directors and the
agents, employees, officers and directors of such controlling person from and
against any losses, liabilities, claims, damages and expenses
<PAGE>
 
                                      -27-

whatsoever (including but not limited to reasonable attorneys' fees and any and
all reasonable expenses whatsoever incurred in investigating, preparing or
defending against any litigation, commenced or threatened, or any claim
whatsoever and any and all reasonable amounts paid in settlement of any claim or
litigation) to which they or either of them may become subject under the Act,
the Exchange Act or otherwise insofar as such losses, liabilities, claims,
damages or expenses (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in the Preliminary Offering Memorandum or the Offering Memorandum, or
in any amendment thereof or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading, in each case to
the extent, but only to the extent, that any such loss, liability, claim, damage
or expense arises out of or is based upon any untrue statement or alleged untrue
statement or omission or alleged omission made therein in reliance upon and in
conformity with written information relating to the Initial Purchaser furnished
to the Company by the Initial Purchaser in writing expressly for use therein.
The Company and the Initial Purchaser acknowledge that the information set forth
in Section 8 is the only information furnished in writing by the Initial
Purchaser to the Company expressly for use in the Offering Memorandum.

          If any action is brought against the Company or the Subsidiary
Guarantors or any such person in respect of which indemnity may be sought
against the Initial Purchaser pursuant to the foregoing paragraph, the Company,
the Subsidiary Guarantors or such person shall promptly notify the Initial
Purchaser in writing of the institution of such action and the Initial Purchaser
shall assume the defense of such action, including the employment of counsel
reasonably satisfactory to such indemnified party and payment of all fees and
expenses, provided, however, that the omission to so notify the Initial
Purchaser shall not relieve the Initial Purchaser from any liability which they
may have to the Company, the Subsidiary Guarantors or any such person or
otherwise.  The Company, the Subsidiary Guarantors or such person shall have the
right to employ its own counsel in any such case, but the fees and expenses of
such counsel shall be at the expense of the Company or such person unless the
employment of such counsel shall have been authorized in writing by the Initial
Purchaser in connection with the defense of such action or the Initial Purchaser
shall not have employed counsel to have charge of the defense of such action or
such indemnified party or parties shall have reasonably concluded that there may
be
<PAGE>
 
                                      -28-

defenses available to it or them which are different from or additional to those
available to the Initial Purchaser (in which case the Initial Purchaser shall
not have the right to direct the defense of such action on behalf of the
indemnified party or parties, but the Initial Purchaser may employ counsel and
participate in the defense thereof but the fees and expenses of such counsel
shall be at the expense of the Initial Purchaser), in any of which events such
fees and expenses shall be borne by the Initial Purchaser and paid as incurred
(it being understood, however, that the Initial Purchaser shall not be liable
for the expenses of more than one separate counsel in any one action or series
of related actions in the same jurisdiction representing the indemnified parties
who are parties to such action).  Anything in this paragraph to the contrary
notwithstanding, the Initial Purchaser shall not be liable for any settlement of
any such claim or action effected without the written consent of the Initial
Purchaser but if settled with the written consent of the Initial Purchaser, the
Initial Purchaser agrees to indemnify and hold harmless the Company, the
Subsidiary Guarantors and any such person from and against any loss or liability
by reason of such settlement.  Notwithstanding the foregoing sentence, if at any
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel as contemplated
by the second sentence of this paragraph, then the indemnifying party agrees
that it shall be liable for any settlement of any proceeding effected without
its written consent if (i) such settlement is entered into more than 60 business
days after receipt by such indemnifying party of the aforesaid request, (ii)
such indemnifying party shall not have reimbursed the indemnified party in
accordance with such request prior to the date of such settlement and (iii) such
indemnified party shall have given the indemnifying party at least 30 days'
prior notice of its intention to settle.  No indemnifying party shall, without
the prior written consent of the indemnified party, effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such proceeding.

          6.   CONTRIBUTION.  In order to provide for contribution in
circumstances in which the indemnification provided for in Section 5 of this
Agreement is for any reason held to be unavailable from the indemnifying party,
or is insufficient to hold harmless a party indemnified under Section 5 of this
Agreement, the Company, the Subsidiary Guarantors and the
<PAGE>
 
                                      -29-

Initial Purchaser shall contribute to the amount paid or payable by such
indemnified party as a result of such aggregate losses, claims, damages,
liabilities and expenses of the nature contemplated by such indemnification
provision (including any investigation, legal and other expenses incurred in
connection with, and any amount paid in settlement of, any action or any claims
asserted) to which the Company and/or the Subsidiary Guarantors and the Initial
Purchaser may be subject (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Subsidiary Guarantors, on the
one hand, and the Initial Purchaser, on the other hand, from the Offering or,
(ii) if such allocation is not permitted by applicable law, in such proportion
as is appropriate to reflect not only the relative benefits referred to in
clause (i) above but also the relative fault of the Company and the Subsidiary
Guarantors, on the one hand, and the Initial Purchaser, on the other hand, in
connection with the statements or omissions that resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations.  The relative benefits received by the Company and the
Subsidiary Guarantors, on the one hand, and the Initial Purchaser, on the other
hand, shall be deemed to be in the same proportion as (x) the total proceeds
from the Offering (net of discounts and commissions but before deducting
expenses) received by the Company and the Subsidiary Guarantors and (y) the
total discounts and commissions received by the Initial Purchaser as set forth
in the table on the cover page of the Offering Memorandum.  The relative fault
of the Company and the Subsidiary Guarantors, on the one hand, and the Initial
Purchaser, on the other hand, shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company (and the Subsidiary Guarantors) or the Initial Purchaser
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission or alleged
statement or omission.

          The Company, the Subsidiary Guarantors and the Initial Purchaser agree
that it would not be just and equitable if contribution pursuant to this Section
6 were determined by pro rata allocation or by any other method of allocation
that does not take into account the equitable considerations referred to above.
Notwithstanding the provisions of this Section 6, (i) in no case shall the
Initial Purchaser be required to contribute any amount in excess of the amount
by which the total discount and commissions applicable to the Notes and Exchange
Notes pursuant to this Agreement exceeds the amount of any damages that the
<PAGE>
 
                                      -30-

Initial Purchaser have otherwise been required to pay by reason of any untrue or
alleged untrue statement or omission or alleged omission and (ii) no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation.  For purposes of this Section 6, each person,
if any, who controls the Initial Purchaser within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act shall have the same rights to
contribution as the Initial Purchaser, and each person, if any, who controls the

national emergency or war, the effect of which shall be, in the Initial
Purchaser's judgment, to make it inadvisable or impracticable to proceed with
the offering or delivery of the Notes on the terms and in the manner
contemplated in the Offering Memorandum or (vi) there shall have been such a
material adverse change in general economic, political or financial conditions

Section 10(b), or if the sale of the Notes provided for in this Agreement is not
consummated because any condition to the obligations of the Initial Purchaser
set forth in this Agreement is not satisfied or because of any refusal,
inability or failure on the part of either of the Company or any Subsidiary
Guarantor to perform any agreement in this Agreement or comply with any
provision of this Agreement, the Company and the Subsidiary Guarantors will,

   SECTION 2.02.  Execution and Authentication;
                  Aggregate Principal Amount.
                  -----------------------------

   Two Officers, or an Officer and an Assistant Secretary, shall sign, or one
Officer shall sign and one Officer or an Assistant Secretary (each of whom
shall, in each case, have been duly authorized by all requisite corporate
actions) shall attest to, the Notes for the Company by manual or facsimile
signature.  Each Subsidiary Guarantor shall execute the Guarantee in the manner
set forth in Section 11.09.

   If an Officer or Assistant Secretary whose signature is on a Note was an
Officer or Assistant Secretary at the time of such execution but no longer holds
that office or position  at the time the Trustee authenticates the Note, the
Note shall nevertheless be valid.

   A Note shall not be valid until an authorized signatory of the Trustee
manually signs the certificate of authentication on the Note.  The signature
shall be conclusive evidence that the Note has been authenticated under this
Indenture.

   The Trustee shall authenticate (i) Initial Notes for original issue in the
aggregate principal amount not to exceed $175,000,000 and (ii) Exchange Notes
from time to time only in exchange for a like principal amount of Initial Notes,
in each case upon a written order of the Company in the form of an Officers'
Certificate of the Company.  Each such written order shall specify the amount of
Notes to be authenticated and the date on which the Notes are to be
authenticated, whether the Notes are to be Initial Notes or Exchange Notes and
whether the Notes are to be issued as Physical Notes or Global Notes or such
other information as the Trustee may reasonably request.  In addition, with
respect to authentication pursuant to clause (ii) of the first sentence of this
paragraph, the first such written order from the Company shall be accompanied by
an Opinion of Counsel of the Company in a form reasonably satisfactory to the
Trustee to the effect that the issuance of the Exchange Notes does not give rise
to an Event of Default, complies with this Indenture and has been duly
authorized by the Company.  The aggregate principal amount of Notes outstanding
at any time may not exceed $175,000,000, except as provided in Section 2.07.

   The Trustee may appoint an authenticating agent (the "Authenticating Agent")
                                                         --------------------  
reasonably acceptable to the Company to authenticate Notes.  Unless otherwise
provided in the appointment, an Authenticating Agent may authenticate Notes
whenever the Trustee may do so.  Each reference in this Indenture to
authentication by the Trustee includes authentication by such Authenticating
Agent.  An Authenticating Agent has the same rights as an Agent to deal with the
Company and Affiliates of the Company.
<PAGE>
 
                                      -25-

in denominations of $1,000 and any integral multiple thereof.

   SECTION 2.03.  Registrar and Paying Agent.
                  -------------------------- 

   The Company shall maintain an office or agency (which shall be located in the
Borough of Manhattan in the City of New York, State of New York) where (a) Notes
may be presented or surrendered for registration of transfer or for exchange
                                                                            
("Registrar"), (b) Notes may be presented or surrendered for  payment ("Paying

Agent") and (c) notices and demands to or upon the Company in respect of the
- -----                                                                       
Notes and this Indenture may be served.  The Registrar shall keep a register of
the Notes and of their transfer and exchange.  The Company, upon prior written
notice to the Trustee, may have one or more co-Registrars and one or more
additional paying agents reasonably acceptable to the Trustee.  The term "Paying
Agent" includes any additional Paying Agent.  Neither the Company nor any
Affiliate of the Company may act as Paying Agent.

   The Company shall enter into an appropriate agency agreement with any Agent
not a party to this Indenture, which agreement shall incorporate the provisions
of the TIA and implement the provisions of this Indenture that relate to such
Agent.  The Company shall notify the Trustee, in advance, of the name and
address of any such Agent.  If the Company fails to maintain a Registrar or
Paying Agent, or fails to give the foregoing notice, the Trustee shall act as
such and shall be entitled to appropriate compensation in accordance with
Section 7.07.

   The Company initially appoints the Trustee as Registrar, Paying Agent and
agent for service of demands and notices in connection with the Notes, until
such time as the Trustee has resigned or a successor has been appointed.  The
Paying Agent or Registrar may resign upon 30 days prior written notice to the
Company.

   SECTION 2.04.  Paying Agent To Hold Assets in Trust.
                  ------------------------------------ 

   The Company shall require each Paying Agent other than the Trustee to agree
in writing that, subject to Articles Ten and Eleven, each Paying Agent shall
hold in trust for the benefit of the Holders or the Trustee all assets held by
the Paying Agent for the payment of principal of, or interest on, the Notes
(whether such assets have been distributed to it by the Company or any other
obligor on the Notes), and the Company and the Paying Agent shall notify the
Trustee in writing of any Default by the Company (or any other obligor on the
Notes) in making any such payment.  The Company at any time may require a Paying
Agent to distribute all assets held by it to the Trustee and account for any
assets disbursed and the Trustee may at any time during the continuance of any
payment Default, upon written request to a Paying Agent, require such Paying
Agent to distribute all assets held by it to the Trustee and to account for any
assets distributed.  Upon distribution to the Trustee of all assets that shall
have been delivered by the Company to the Paying Agent, the Paying Agent shall
have no further liability for such assets.

   SECTION 2.05.  Noteholder Lists.
                  ---------------- 

   The Trustee shall preserve in as current a form as is reasonably practicable
the most recent list available to it of the names and addresses of Noteholders.
If the Trustee is not the Registrar, the Company shall furnish or cause the
Registrar to furnish to the Trustee as of each Record Date and before each
related Interest Payment Date and at such other times as the Trustee may request
in writing a list as of such date and in such form as the Trustee may reasonably
require of the names and addresses of Noteholders, which list may be
conclusively relied upon by the Trustee.

   The registered Holder of any Note, as shown on the Noteholder list maintained
by the Registrar, shall be deemed and regarded as the absolute owner thereof for
all purposes, whether or not such Note is overdue, and payment of or on account
of any of the principal of or interest on such Note shall be made only to or
upon the order of the registered Holder thereof or his duly authorized attorney;
but such registration may be changed as herein expressly provided.  All such
payments shall be valid and effectual to satisfy and discharge the liability
upon such Note to the extent of the sum or sums so paid.  Neither the Company
nor the Trustee, nor any agent for either, shall be bound or otherwise obligated
by any notice or knowledge indicating that any Person other than the registered
Holder shown on the Noteholder list is the Holder of any Note except for a
formal change of registration by transfer or otherwise as provided herein.

   SECTION 2.06.  Transfer and Exchange.
                  --------------------- 

   Subject to the provisions of Sections 2.15 and 2.16, when Notes are presented
to the Registrar or a co-Registrar with a request to register the transfer of
such Notes or to exchange such Notes for an equal principal amount of Notes of
other authorized denominations, the Registrar or co-Registrar shall register the
transfer or make the exchange as requested if its requirements for such
transaction are met; provided, however, that the Notes presented or surrendered
for registration of transfer or exchange shall be duly endorsed or accompanied
by a written instrument of transfer in form satisfactory to the Company and the
Registrar or co-Registrar, duly executed by the Holder thereof or his attorney
duly authorized in writing.  To permit registrations of transfer and exchanges,
the Company shall issue and execute and the Trustee shall authenticate Notes at
the Registrar's or co-Registrar's request.  No service charge shall be made to a
Noteholder for any registration of transfer or exchange.  The Company may
require from such Noteholder payment of a sum sufficient to cover any transfer
tax or similar governmental charge payable in connection therewith (other than
any such transfer taxes or similar governmental charge payable upon exchanges or
transfers pursuant to Section 2.10, 3.06, 4.15, 4.16 or 9.06, in which event the
Company shall be responsible for the payment of such taxes).

   The Registrar or co-Registrar shall not be required to register the transfer
of or exchange of any Note (i) during a period beginning at the opening of
business 15 days before the mailing
<PAGE>
 
                                      -27-

of a notice of redemption of Notes and ending at the close of business on the
day of such mailing and (ii) selected for redemption in whole or in part
pursuant to Article Three, except the unredeemed portion of any Note being
redeemed in part.

   Any Holder of a Global Note shall, by acceptance of such Global Note, agree
that transfers of beneficial interests in such Global Note may be effected only
through a book entry system maintained by the Holder of such Global Note (or its
agent), and that ownership of a beneficial interest in the Note shall be
required to be reflected in a book entry.

   SECTION 2.07.  Replacement Notes.
                  ----------------- 

   If a mutilated Note is surrendered to the Trustee or if the Holder of a Note
claims that the Note has been lost, destroyed or wrongfully taken, the Company
shall issue and execute and the Trustee shall authenticate a replacement Note if
the Trustee's requirements are met.  If required by the Trustee or the Company,
such Holder must provide an affidavit of lost certificate and an indemnity bond
or other indemnity, sufficient in the judgment of both the Company and the
Trustee, to protect the Company, the Trustee or any Agent from any loss which
any of them may suffer if a Note is replaced.  The Company may charge such
Holder for its reasonable out-of-pocket expenses in replacing a Note, including
reasonable fees and expenses of the Trustee and counsel and the Trustee may
charge the Company for the Trustee's reasonable out-of-pocket expenses in
replacing such Note.  Every replacement Note shall constitute an additional
Obligation of the Company.

   SECTION 2.08.  Outstanding Notes.
                  ----------------- 

   Notes outstanding at any time are all the Notes that have been authenticated
by the Trustee except those cancelled by it, those delivered to it for
cancellation and those described in this Section as not outstanding.  Subject to
the provisions of Section 2.09, a Note does not cease to be outstanding because
the Company, any Subsidiary Guarantor or any of their respective Affiliates
holds the Note.

   If a Note is replaced pursuant to Section 2.07 (other than a mutilated Note
surrendered for replacement), it ceases to be outstanding unless the Trustee
receives proof satisfactory to it that the replaced Note is held by a bona fide
purchaser.  A mutilated Note ceases to be outstanding upon surrender of such
Note and replacement thereof pursuant to Section 2.07.

   If on a Redemption Date or the Maturity Date the Paying Agent holds U.S.
Legal Tender or U.S. Government Obligations sufficient to pay all of the
principal and interest due on the Notes payable on that date and is not
prohibited from paying such money to the Holders thereof pursuant to the  terms
of this Indenture, then on and after that date such Notes cease to be
outstanding and interest on them ceases to accrue.

   SECTION 2.09.  Treasury Notes.
                  -------------- 

   In determining whether the Holders of the required principal amount of Notes
have concurred in any direction, waiver, consent or notice, Notes owned by the
Company, any Subsidiary Guarantor or any of their respective Affiliates shall be
considered as though they are not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Notes which a Trust Officer of the Trustee
actually knows are so owned shall be so considered.  The Company shall notify
the Trustee, in writing, when it or any of its Affiliates repurchases or
otherwise acquires Notes, and of the aggregate principal amount of such Notes so
repurchased or otherwise acquired.

   SECTION 2.10.  Temporary Notes.
                  --------------- 

   Until definitive Notes are ready for delivery, the Company may prepare and
the Trustee shall authenticate temporary Notes upon receipt of a written order
of the Company in the form of an Officers' Certificate.  The Officers'
Certificate shall specify the amount of temporary Notes to be authenticated and
the date on which the temporary Notes are to be authenticated, and shall direct
the Trustee to authenticate such Notes and certify that all conditions precedent
to the issuance of such Notes contained herein have been complied with.
Temporary Notes shall be substantially in the form of definitive Notes but may
have variations that the Company and the Trustee consider appropriate for
temporary Notes.  Without unreasonable delay, the Company shall prepare and the
Trustee shall authenticate upon receipt of a written order of the Company
pursuant to Section 2.02 definitive Notes in exchange for temporary Notes.

   SECTION 2.11.  Cancellation.
                  ------------ 

   The Company at any time may deliver Notes to the Trustee for cancellation.
The Registrar and the Paying Agent shall forward to the Trustee any Notes
surrendered to them for transfer, exchange or payment.  The Trustee, or at the
direction of the Trustee, the Registrar or the Paying Agent, and no one else,
shall cancel and, at the written direction of the Company, shall (subject to the
record-retention requirements of the Exchange Act) dispose of all Notes
surrendered for registration of transfer, exchange, payment or  cancellation.
Subject to Section 2.07, the Company may not issue new Notes to replace Notes
that it has paid or delivered to the Trustee for cancellation.  If the Company
or any Subsidiary Guarantor shall acquire any of the Notes, such acquisition
shall not operate as a redemption or satisfaction of the Indebtedness
represented by such Notes unless and until the same are surrendered to the
Trustee for cancellation pursuant to this Section 2.11.

                                      -29-

   SECTION 2.12.  Defaulted Interest.
                  ------------------ 

   If the Company defaults in a payment of interest on the Notes, it shall pay
the defaulted interest, plus (to the extent lawful) any interest payable on the
defaulted interest to the Persons who are Holders on a subsequent special record
date, which date shall be the fifteenth day next preceding the date fixed by the
Company for the payment of defaulted interest or the next succeeding Business
Day if such date is not a Business Day.  At least 15 days before the subsequent
special record date, the Company shall mail to each Holder, with a copy to the
Trustee, a notice that states the subsequent special record date, the payment
date and the amount of defaulted interest, and interest payable on such
defaulted interest, if any, to be paid.

   SECTION 2.13.  CUSIP Number.
                  ------------ 

   The Company in issuing the Notes may use one or more "CUSIP" numbers, and if
so, the appropriate CUSIP number(s) shall be included in all notices of
redemption or exchange as a convenience to Holders; provided that any such
notice may state that no representation is made by the Trustee as to the
correctness or accuracy of any CUSIP number(s) printed in the notice or on the
Notes, and that reliance may be placed only on the other identification numbers
printed on the Notes.  The Company shall promptly notify the Trustee of any
change in the CUSIP number.

   SECTION 2.14.  Deposit of Moneys.
                  ----------------- 

   Prior to 10:00 a.m, New York City time, on each Interest Payment Date and on
the Maturity Date, the Company shall have deposited with the Paying Agent in
immediately available funds money sufficient to make cash payments, if any, due
on such Interest Payment Date or Maturity Date, as the case may be, in a timely
manner which permits the Paying Agent to remit payment to the Holders on such
Interest Payment Date or Maturity Date, as the case may be.

   SECTION 2.15.  Book-Entry Provisions for
                  Global Notes.
                  ---------------------------

   (a) Any Global Note initially shall (i) be registered in the name of the
Depository or the nominee of such Depository, (ii) be delivered to the Trustee
as custodian for such Depository and (iii) bear legends as set forth in Exhibit
B.

   Members of, or participants in, the Depository ("Agent Members") shall have
                                                    -------------             
no rights under this Indenture with respect to any Global Note held on their
behalf by the Depository, or the Trustee as its custodian, or under any Global
Note, and the Depository may be treated by the Company, the Trustee and any
agent of the Company or the Trustee as the absolute owner of the
<PAGE>
 
                                      -30-

herein shall prevent the Company, the Trustee or any agent of the Company or the

transferred to all beneficial owners in exchange for their beneficial interests
in a Global Note if (i) the Depository notifies the Company that it is unwilling

depositary is not appointed by the Company within 90 days of such notice or (ii)
an Event of Default has occurred and is continuing and the Registrar has
received a request from the Depository to issue Physical Notes.

   (c) In connection with any transfer or exchange of a portion of the
beneficial interest in a Global Note to beneficial owners pursuant to paragraph
(b), the Registrar shall (if one or more Physical Notes are to be issued)
reflect on its books and records the date and a decrease in the principal amount
of such Global Note in an amount equal to the principal amount of the beneficial
interest in such Global Note to be transferred, and the Company shall execute,
and the Trustee shall authenticate and deliver, one or more Physical Notes of
like tenor and amount.

   (d) In connection with the transfer of an entire Global Note to beneficial
owners pursuant to paragraph (b), such Global Note shall be deemed to be

the Trustee shall authenticate and deliver, to each beneficial owner identified
by the Depository in exchange for its beneficial interest in such Global Note,
an equal aggregate principal amount of Physical Notes of authorized
denominations.

   (e) Any Physical Note constituting a Restricted Security delivered in
exchange for an interest in a Global Note pursuant to paragraph (b) or (c)
shall, except as otherwise provided by paragraphs (a)(i)(x) and (c) of Section
2.16, bear the legend regarding transfer restrictions applicable to the Physical
Notes set forth in Exhibit A.

   (f) The Holder of any Global Note may grant proxies and otherwise authorize
any person, including Agent Members and persons that may hold interests through
Agent Members, to take any action which a Holder is entitled to take under this

     If the Company elects to redeem Notes pursuant to Paragraph Six of the
Notes, it shall notify both the Trustee and the Paying Agent in writing of the
Redemption Date and the principal amount of the Notes to be redeemed.

     The Company shall give each notice provided for in this Section 3.01 at
least 45 days before the Redemption Date (unless a shorter notice period shall
be satisfactory to the Trustee, as evidenced in a writing signed on behalf of
the Trustee), together with an Officers' Certificate and Opinion of Counsel
stating that such redemption shall comply with the conditions contained herein
and in the Notes.

     SECTION 3.02.      Selection of Notes To Be Redeemed.
                        --------------------------------- 

     If fewer than all of the Notes are to be redeemed, the Trustee shall select
the Notes to be redeemed on a pro rata basis, by lot or in such other fair and
appropriate manner chosen at the discretion of the Trustee and, if the Notes are
listed on any securities exchange, by a method that complies with the
requirements of such exchange; provided, however, that if partial redemption is
made with the net proceeds of one or more issuances of Common Stock (other than
Redeemable Stock) prior to December 1, 2000, selection of the Notes or portions
thereof for redemption shall be made by the Trustee only on a pro rata basis
unless such method is otherwise prohibited.  The Trustee shall make the
selection from the Notes outstanding and not previously called for redemption
and shall promptly notify the Company in writing of the Notes selected for
redemption and, in the case of any Note selected for partial redemption, the
principal amount thereof to be redeemed.  Notes in denominations of $1,000 may
be redeemed only in whole.  The Trustee may select for redemption portions
(equal to $1,000 or any integral multiple thereof) of the principal of Notes
that have denominations larger than $1,000.  Provisions of this Indenture that
apply to Notes called for redemption also apply to portions of Notes called for
redemption.

     SECTION 3.03.      Notice of Redemption.
                        -------------------- 

     At least 30 days but not more than 60 days before a Redemption Date, the
Company shall mail or cause to be mailed a notice of redemption by first class
mail, postage prepaid, to each Holder whose Notes are to be redeemed, with a
copy to the Trustee and any Paying Agent.

     Each notice for redemption shall identify the Notes to be redeemed and
shall state:

          (1)  the Redemption Date;

          (2) the Redemption Price and the amount of accrued interest, if any,
     to be paid;

          (3) the name and address of the Paying Agent;
<PAGE>
 
                                      -34-


          (4) the subparagraph of the Notes pursuant to which such redemption is
     being made;

          (5) that Notes called for redemption must be surrendered to the Paying
     Agent to collect the Redemption Price plus accrued interest, if any;

          (6) that, unless (a) the Company defaults in making the redemption
     payment or (b) such redemption payment is prohibited pursuant to Article
     Ten or Eleven or otherwise, interest on Notes called for redemption ceases
     to accrue on and after the Redemption Date, and the only remaining right of
     the Holders of such Notes is to receive payment of the Redemption Price
     plus accrued interest, if any, upon surrender to the Paying Agent of the
     Notes redeemed;

          (7) if any Note is being redeemed in part, the portion of the
     principal amount (equal to $1,000 or any integral multiple thereof) of such
     Note to be redeemed and that, on or after the Redemption Date, and upon
     surrender of such Note, a new Note or Notes in the aggregate principal
     amount equal to the unredeemed portion thereof will be issued; and

          (8) if fewer than all the Notes are to be redeemed, the identification
     of the particular Notes (or portion thereof) to be redeemed, as well as the
     aggregate principal amount of Notes to be redeemed and the aggregate
     principal amount of Notes to be outstanding after such partial redemption.

     SECTION 3.04.  Effect of Notice of Redemption.
                    ------------------------------ 

     Once notice of redemption is mailed in accordance with Section 3.03, Notes
called for redemption become due and payable on the Redemption Date and at the
Redemption Price plus accrued interest, if any.  Upon surrender to the Trustee
or Paying Agent, such Notes called for redemption, unless  prohibited pursuant
to Article Ten or Eleven or otherwise pursuant to this Indenture, shall be paid
at the Redemption Price (which shall include accrued interest thereon to the
Redemption Date), but installments of interest, the maturity of which is on or
prior to the Redemption Date, shall be payable to Holders of record at the close
of business on the relevant record dates referred to in the Notes.

     SECTION 3.05.  Deposit of Redemption Price.
                    --------------------------- 

     On or before the Redemption Date, the Company shall deposit with the Paying
Agent in immediately available funds U.S. Legal Tender sufficient to pay the
Redemption Price plus accrued interest, if any, of all Notes or portions thereof
to be redeemed on that  date.  The Paying Agent shall promptly return to the
Company any U.S. Legal Tender so deposited which is not required for that
purpose, except with respect to monies owed as obligations to the Trustee
pursuant to Article Seven.
<PAGE>
 
                                      -35-

     If the Company complies with the preceding paragraph and payment of the
Notes is not prohibited under Article Ten or Eleven or otherwise, then, unless
the Company defaults in the payment of such Redemption Price plus accrued
interest, if any, interest on the Notes to be redeemed will cease to accrue on
and after the applicable Redemption Date, whether or not such Notes are
presented for payment.

     SECTION 3.06.  Notes Redeemed in Part.
                    ---------------------- 

     Upon surrender of a Note that is to be redeemed in part, the Company shall

location, and any change in the location, of such office or agency.  If at any

cause to be done, at its own cost and expense, all things necessary to preserve
and keep in full force and effect its corporate existence and the corporate
existence of each of its Subsidiaries in accordance with the respective
organizational documents of each such Subsidiary and the material rights
(charter and statutory) of the Company and each such Subsidiary; provided,
however, that the Company shall not be required to preserve, with respect to

governmental charges (including withholding taxes and any penalties, interest
and additions to taxes) levied or imposed upon it or any of its  Subsidiaries or
its Properties or any of its Subsidiaries' Properties and (ii) all material
lawful claims for labor, materials and supplies that, if unpaid, might by law
become a Lien upon its Properties or any of its Subsidiaries' Properties,

have a material adverse effect on the business and financial condition of the
Company and its Subsidiaries, taken as a whole; provided, however, that the
Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability

wear and tear) and make all necessary repairs, renewals, replacements,

insurance) against loss or damage of the kinds that, in the good faith judgment
of the Company, are adequate and appropriate for the conduct of the business of
the Company and its Subsidiaries in a prudent manner, with reputable insurers or

the principal amount thereof, with an original issue price) not to exceed the
amount so exchanged or refinanced (plus accrued interest, fees, expenses and
other obligations related thereto); provided that if the Debt to be exchanged or
refinanced by its terms ranks subordinate in right of payment to the Notes, (1)
the Debt exchanged for, or the proceeds of which are used to refinance, such

that the Debt to be exchanged or refinanced is subordinate to the Notes) in

limitation, at the option of the 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 this Indenture, and such Debt provides that the Company will not
repurchase such Debt pursuant to such provisions prior to the Company's

     SECTION 4.13.  Limitation on Payment Restrictions
                    Affecting Subsidiaries.
                    --------------------------------------

     The Company shall not, and shall not permit any Subsidiary to, create,

Indenture (including without limitation the New Credit Facilities as in effect
on the Issue Date) 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,

less favorable to the Company than those in such agreement in effect on the date
of this 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

Subsidiary arising from a Receivables Transaction.  This section will not
prevent the Company from Incurring or suffering to exist any Lien which is

     SECTION 4.14.  Limitation on Additional Senior
                    Subordinated Indebtedness.
                    --------------------------------
<PAGE>
 
                                      -43-

     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.

     SECTION 4.15.  Limitation on Change of Control.
                    ------------------------------- 

     (a) Upon a Change of Control, each Holder of the Notes will have the right
to 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 (b) (the "Change of Control Offer").
                                                  -----------------------   

     (b) Within 30 days following any Change of Control, the Company shall 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 circumstances
                    --------------------------------                         
and relevant facts regarding such Change of Control (including information with
respect to pro forma historical income, cash flow and capitalization after
giving effect to such Change of Control); (3) the repurchase date (which will be
not earlier than 30 days or later than 60 days 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 purchased pursuant to a Change of Control
Offer will be required to surrender the Note, with the form entitled "Option of
Holder to Elect Purchase" on the reverse of the Note completed, to the paying
agent at the address specified in the notice prior to the close of business on
the Repurchase Date; (7) that holders will be entitled to withdraw their
election if the paying agent receives, not later than the close of business on
the third Business Day (or such shorter periods as may be required by applicable
law) preceding the Repurchase Date, a telegram, telex, facsimile transmission or
letter setting forth the name of the holder, the principal amount of Notes the
holder delivered for purchase, and a statement that such holder is withdrawing
his election to have such Notes purchased; and (8) that holders which elect to
have their Notes purchased only in part will be issued new Notes in a principal
amount equal to the unpurchased portion of the Notes surrendered.
<PAGE>
 
                                      -44-

     (c) On the Repurchase Date, the Company shall (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 Trustee will promptly
mail to the holders of Note so accepted payment in an 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 the Note surrendered. The
Company shall publicly announce the results of the Change of Control Offer on or
as soon as practicable after the Repurchase Date.

     (d) 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 (c), but in any event within 20 days following any Change of
Control, the Company shall (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 set forth above.  The Company must first comply
with 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 preceding sentence shall constitute an Event of Default pursuant to clause
(c) of Section 6.01 if not cured within 30 days after the notice required by
such clause.  Failure by the Company to make a Change of Control Offer when
required by this Indenture constitutes a default under this Indenture and, if
not cured within 30 days after notice, constitutes an Event of Default.

     (e) 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 the
Change of Control Offer and shall otherwise have consummated the Change of
Control Offer made to holders of the Notes.  The Company shall 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 this Indenture.

     (f) 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 shall comply with the requirements of
Rule 14e-1 as then in effect with respect to such repurchase.

     SECTION 4.16.  Limitation on Asset Dispositions.
                    -------------------------------- 

     (a) Except for any Asset Disposition permitted to be made as set forth in
Article Five, 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 shall not make, and shall 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 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 Sale 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 set forth in the following paragraph (b). 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 set forth 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 set forth 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
<PAGE>
 
                                      -46-

so affected may be retained by the applicable Subsidiary for so long as
such material adverse tax cost event would continue.

     (b) In the event Net Cash Proceeds are required to be applied to the
purchase of Notes as set forth in clause (iii) of the preceding paragraph (a),
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 over
subscription) set forth in this 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 this Indenture.  The Company will not be
required to make an Offer for Notes 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).

     (c)  (i)  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 shall 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 set forth
     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
     set forth in clause (iii) below.

     The notice shall also specify a purchase date not less than 30 days nor
more than 60 days after the date of such notice (the "Purchase Date") and shall
                                                      -------------            
include all instructions and materials necessary to enable each Holder to tender
notes pursuant to the Offer and shall contain information concerning the
business of the Company which the Company in good faith believes will enable
such Holders to make an informed decision, which at a minimum will include:  (A)
(1) the most recently filed annual report on Form 10-K (including audited
consolidated financial statements) of the Company, the most recent subsequently
filed quarterly report on Form 10-Q
<PAGE>
 
                                      -47-

and any current report on Form 8-K of the Company filed subsequent to such
quarterly report, other than current reports describing the Asset Dispositions
otherwise described in the offering materials or (2) corresponding successor
reports or reports otherwise required to be delivered to Holders if the Company
is not filing reports pursuant to the Exchange Act, (B) a description of
material developments in the Company's business subsequent to the date of the
latest of such reports, and (C) if material, appropriate pro forma financial
information.

     (ii)  Not later than the date upon which written notice of an Offer is
delivered to the Trustee as provided above, the Company shall deliver to the
Trustee an Officers' Certificate as to (A) the amount of the Offer (the "Offer
                                                                         -----
Amount"), (B) the allocation of the Net Cash Proceeds pursuant to which such
- ------                                                                      
Offer is being made and (C) the compliance of such allocation with the
provisions of Section 4.10(a).  Not later than one Business Day prior to the
Purchase Date, the Company shall also irrevocably deposit with the Trustee or
with a paying agent (or, if the Company is acting as its own paying agent,
segregate and hold in trust) in immediately available funds an amount equal to
the Offer Amount to be held for payment in accordance with the provisions of
this Section.  Upon the expiration of the period for which the Offer remains
open (the "Offer Period"), the Company shall deliver to the Trustee the Notes or
           ------------                                                         
portions thereof which have been properly tendered to and are to be accepted by
the Company.  The Trustee or a paying agent (if any) shall, on the Purchase
Date, mail or deliver payment to each tendering Holder in the amount of the
purchase price.  In the event that the aggregate purchase price of the Notes
delivered by the Company to the Trustee is Less than the Offer Amount, the
Trustee shall deliver the excess to the Company immediately after the expiration
of the Offer Period.

     (iii)  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.

     (iv)  At the time the Company delivers Notes to the Trustee which are to be
accepted for purchase, the Company will also deliver an Officers' Certificate
stating that such Notes are to be accepted by the Company pursuant to and in
accordance with the terms of this Section.  A Note shall be deemed to have been
accepted for purchase at the time the Trustee, directly or through an agent,
mails or delivers payment therefor to the surrendering Holder.
<PAGE>
 
                                      -48-

     (d) 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 set forth in clause (iii) of paragraph (a) of this
Section 4.16.

     (e) Whenever Net Cash Proceeds are received by the Company, and prior to
the allocation of such Net Cash Proceeds as set forth in this Section 4.16, such
Net Cash Proceeds will be set aside by the Company in a separate account pending
allocation.

     (f) The Company will comply with all applicable securities laws in
connection with any Offer, including Rule l4e-1 under the Exchange Act.

     SECTION 4.17.  Limitation on Issuance of
                    Subsidiary Preferred Stock.
                    -------------------------- 

     The Company shall 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 pursuant to Section 4.12 in an aggregate
principal amount equal to the aggregate liquidation value of such Preferred
Stock.

     SECTION 4.18.  Limitation on Liens.
                    ------------------- 

     The Company shall not, and shall 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
this 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 this 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.


     SECTION 4.19.  Limitation on Sale and Leaseback
                    Transactions.
                    --------------------------------------
<PAGE>
 
                                      -49-

     The Company shall not and shall 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 Section 4.12.

     SECTION 4.20.  Limitation on Guarantees of Debt
                    by Subsidiaries.
                    -------------------------------------

     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 shall cause such Subsidiary to concurrently Guarantee the Company's
Obligations under this 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 this Indenture (which
subordination will be substantially identical to the subordination provisions of
this 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 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
this Indenture being so Guaranteed.

     (a) The Company, in a single transaction or through a series of related
transactions, shall not consolidate with or merge with or into any other person,

laws of the United States, any state thereof or the District of Columbia,
and if other than the Company shall expressly assume, by a supplemental
indenture, all of the obligations of the Company under the Notes and this
Indenture; (ii) immediately after and giving effect to such transaction on a pro
forma basis and the assumption contemplated by clause (i) above and the
incurrence or anticipated incurrence of any Debt to be incurred in connection
therewith, the Surviving person could incur at least $1.00 of Debt pursuant to
the second paragraph of Section 4.12; (iii) immediately before and immediately
after and giving effect to such transaction and the assumption of the
obligations as set forth in clause (i) above and the incurrence or anticipated
incurrence of any Debt to be incurred in connection therewith, no Default or
Event of Default shall have occurred and be continuing; (iv) the Net Worth of
the Surviving person on a pro forma basis after giving effect to the transaction
is not less than the Net Worth of the Company immediately prior to such
transaction and (v) the Surviving person shall have delivered to the Trustee an
officers' certificate stating that such consolidation, merger, sale, assignment,
transfer, lease, conveyance or other disposition and, if a supplemental
indenture is required in connection with such transaction, such supplemental
indenture comply with this Article Five and that all conditions precedent herein
provided relating to such transaction have been satisfied.

     (b) For purposes of clause (a) above, the transfer (by lease, assignment,
sale or otherwise, in a single transaction or series of transactions) of all or
substantially all of the properties and assets of one or more Subsidiaries of
the Company the Capital Stock of which constitutes all or substantially all of
the properties and assets of the Company shall be deemed to be the transfer of
all or substantially all of the properties and assets of the Company.
Notwithstanding the foregoing clauses (a)(ii) and (a)(iii) of this Section 5.01,
(a) any Subsidiary of the Company may consolidate with, merge into or transfer
all or part of its properties and assets to the Company or a Subsidiary
Guarantor and (b) the Company may merge with an Affiliate incorporated
principally (as determined in good faith by the Board of Directors of the
Company and evidenced by a Board Resolution) for the purpose of reincorporating
the Company in another jurisdiction, and such transaction does not have as one
of its purposes the evasion of the foregoing limitations.

     SECTION 5.02.  Successor Corporation Substituted.
                    --------------------------------- 

     Upon any consolidation, combination or merger or any transfer of all or
substantially all of the assets of the Company in accordance with this Article
Five, the surviving entity shall succeed to, and be substituted for, and may
exercise every right and power of, the Company under this Indenture and the
Notes with the same effect as if such surviving entity had been
<PAGE>
 
                                      -51-

named as such, and thereafter the predecessor corporation shall be relieved of
all Obligations and covenants under this Indenture and the Notes.


                                  ARTICLE SIX

                              DEFAULT AND REMEDIES

     SECTION 6.01.  Events of Default.
                    ----------------- 

     An "Event of Default" occurs if any one or more of the following (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 (whether or not prohibited by the
     subordination provisions of this Indenture);

          (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 (whether or not prohibited by the subordination provisions of
     this Indenture);

          (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 this 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 this 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 Law
     now or hereafter in effect or seeking the appointment of a 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
<PAGE>
 
                                      -52-

     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 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
     Custodian (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
     this 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 holders of such indebtedness, then
     the Event of Default under this 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;
<PAGE>
 
                                      -53-

          (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; or

          (j) any Subsidiary Guarantee shall for any reason cease to be
          in full force and effect or be declared null and void or any
          responsible officer of the Company or any Subsidiary Guarantor denies
          that it has any further liability under any Subsidiary Guarantee or
          gives notice to such effect (other than by reason of the termination
          of this Indenture or the release of any such Subsidiary Guarantee in
          accordance with this Indenture).

     SECTION 6.02.  Acceleration.
                    ------------ 

     In the event of an Event of Default specified in Section 6.01, 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 this
Indenture, by notice in writing to the Company (and to the Trustee if given by
Noteholders) (an "Acceleration Notice"), 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) of Section
6.01 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 this Indenture.

     SECTION 6.03.  Other Remedies.
                    -------------- 

     If an Event of Default occurs and is continuing, the Trustee may pursue any
available remedy by proceeding at law or in equity to collect the payment of
principal of or interest on the Notes or to enforce the performance of any
provision of the Notes or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default.  No remedy
<PAGE>
 
                                      -54-

is exclusive of any other remedy. All available remedies are cumulative to the
extent permitted by law.


     SECTION 6.04.  Waiver of Past Defaults.
                    ----------------------- 

     Subject to Sections 2.09, 6.07 and 9.02, the Holders of a majority in
principal amount of the outstanding Notes by notice to the Trustee may waive an
existing Default or Event of Default and its consequences, except a Default in
the payment of principal of or interest on any Note as specified in clauses (a)
and (b) of Section 6.01.  When a Default or Event of Default is waived, it is
cured and ceases.

     SECTION 6.05.  Control by Majority.
                    ------------------- 

     Subject to Section 2.09, the Holders of a majority in 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 it, including, without limitation, any remedies provided for
in Section 6.03.  Subject to Section 7.01, however, the Trustee may refuse to
follow any direction that the Trustee reasonably believes conflicts with any law
or this Indenture, that the Trustee determines may be unduly prejudicial to the
rights of another Holder, or that may involve the Trustee in personal liability;
provided that the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction.

     SECTION 6.06.  Limitation on Suits.
                    ------------------- 

     A Holder may not pursue any remedy with respect to this Indenture or the
Notes unless:

          (1) the Holder gives to the Trustee written notice of a continuing
     Event of Default;

          (2) Holders of at least 25% in principal amount of the then
     outstanding Notes make a written request to the Trustee to pursue the
     remedy;

          (3) such Holder or Holders offer to the Trustee indemnity reasonably
     satisfactory to the Trustee against any loss, liability or expense to be
     incurred in compliance with such request;

          (4) the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer of satisfactory indemnity; and
<PAGE>
 
                                      -55-

          (5) during such 60-day period the Holders of a majority in principal
     amount of the outstanding Notes do not give the Trustee a direction which,
     in the opinion of the Trustee, is inconsistent with the request.

     The foregoing limitations shall not apply to a suit instituted by a Holder
for the enforcement of the payment of principal and premium, if any, or interest
on such Note on or after the respective due dates set forth in such Note
(including upon acceleration thereof); provided that upon institution of any
proceeding or exercise of any remedy, such Holders provide the Trustee with
prompt written notice thereof.

     A Holder may not use this Indenture to prejudice the rights of another
Holder or to obtain a preference or priority over such other Holder.

     SECTION 6.07.  Rights of Holders To Receive Payment.
                    ------------------------------------ 

     Notwithstanding any other provision of this Indenture, the right of any
Holder to receive payment of principal of and interest on a Note, on or after
the respective due dates expressed in such Note, or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

     SECTION 6.08.  Collection Suit by Trustee.
                    -------------------------- 

     If an Event of Default in payment of principal or interest specified in
clause (a) or (b) of Section 6.01 occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company,  any Subsidiary Guarantor, if any, or any other obligor on the Notes
for the whole amount of principal and accrued interest remaining unpaid,
together with interest on overdue principal and, to the extent that payment of
such interest is lawful, interest on overdue installments of interest, in each
case at the rate per annum borne by the Notes, and such further amount as shall
be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

     SECTION 6.09.  Trustee May File Proofs of Claim.
                    -------------------------------- 

     The Trustee may file such proofs of claim and other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, taxes,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders allowed in any judicial proceedings relating to the Company or any other
obligor upon the Notes, any of their respective creditors or any of their
respective property and shall be entitled and empowered to collect and receive
any monies or other property payable or deliverable on any such claims and to
distribute the same, and any Custodian in any such
<PAGE>
 
                                      -56-

judicial proceedings is hereby authorized by each Holder to make such payments
to the Trustee and, in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, taxes, disbursements and advances
of the Trustee, its agent and counsel, and any other amounts due the Trustee
under Section 7.07. The Company's payment obligations under this Section 6.09
shall be secured in accordance with the provisions of Section 7.07. Nothing
herein contained shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

     SECTION 6.10.  Priorities.
                    ---------- 

     If the Trustee collects any money or property pursuant to this Article Six,
it shall pay out the money in the following order:

          First:  to the Trustee for amounts due under Section 7.07;

          Second:  subject to Articles Ten and Eleven, to Holders for amounts
     due and unpaid on the Notes for interest and premium, ratably, without
     preference or priority of any kind, according to the amounts due and
     payable on the Notes for interest and premium, respectively;

          Third:  subject to Articles Ten and Eleven, to Holders for amounts due
     and unpaid on the Notes for principal, ratably without preference or
     priority of any kind, according to the amounts due and payable on the Notes
     for principal; and

          Fourth:  subject to Articles Ten and Eleven, to the Company, the
     Subsidiary Guarantors, if any, or any other obligor on the Notes, as their
     interests may appear, or as a court of competent jurisdiction may direct.

     The Trustee, upon prior notice to the Company, may fix a record date and
payment date for any payment to Holders pursuant to this Section 6.10.

     SECTION 6.11.  Undertaking for Costs.
                    --------------------- 

     In any suit for the enforcement of any right or remedy under this Indenture
or in any suit against the Trustee for any action taken or omitted by it as
Trustee, a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
<PAGE>
 
                                      -57-

against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant.  This Section 6.11
does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section
6.07, or a suit by a Holder or Holders of more than 10% in principal amount of
the outstanding Notes.


     SECTION 6.12.  Restoration of Rights and Remedies.
                    ---------------------------------- 

     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture or any Note and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case the Company, the
Trustee and the Holders shall, subject to any determination in such proceeding,
be restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

                                 ARTICLE SEVEN

                                    TRUSTEE

     SECTION 7.01.  Duties of Trustee.
                    ------------------

     (a) If an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture and
use the same degree of care and skill in its exercise thereof as a prudent
person would exercise or use under the circumstances in the conduct of his own
affairs.

     (b) Except during the continuance of an Event of Default:

          (1) The Trustee need perform only those duties as are specifically set
     forth in this Indenture and the TIA and no others and no covenants or
     obligations shall be implied in this Indenture against the Trustee.  To the
     extent of any conflict between the duties of the Trustee hereunder and
     under the TIA, the TIA shall control.

          (2) In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture.  However,
     in the case of any such certificate or opinion which by any provision
     hereof is specifically required to be furnished to the Trustee, the Trustee
     shall examine the certificates and opinions to determine whether or not
     they conform to the requirements of this Indenture.

     this Section 7.01.

     (d) No provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the performance

if it shall have reasonable grounds for believing that repayment of such funds
or adequate indemnity against such risk or liability is not reasonably assured
to it.

     (e) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b), (c) and (d) of this Section 7.01.

                    ----------------- 

     Subject to Section 7.01:

          (a) The Trustee may rely and shall be fully protected in acting or
     refraining from acting upon any document believed by it to be genuine and
     to have been signed or presented by the proper Person.  The Trustee need
     not investigate any fact or matter stated in the document.

          (b) Before the Trustee acts or refrains from acting, it may consult
     with counsel and may require an Officers' Certificate or an Opinion of
     Counsel, or both, which shall conform to Sections 12.04 and 12.05.  The
     Trustee shall not be liable for any action it
<PAGE>
 
                                      -59-

     takes or omits to take in good faith in reliance on such Officers'
     Certificate or Opinion of Counsel.

     appointed with due care.

          (e) The Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, notice, request, direction, consent, order, bond,
     debenture, or other paper or document, but the Trustee, in its discretion,
     may make such further inquiry or investigation into such facts or matters
     as it may see fit.

          (f) The Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request, order or
     direction of any of the Holders pursuant to the provisions of this
     Indenture, unless such Holders shall have offered to the Trustee security
     or indemnity reasonably satisfactory to the Trustee against the costs,
     expenses and liabilities which may be incurred by it in compliance with
     such request, order or direction.

          (g) The Trustee may consult with counsel and the advice or opinion of
     such counsel as to matters of law shall be full and complete authorization

     opinion of such counsel.

     notice of such Default or Event of Default shall have been given to the

     thereof.

     SECTION 7.03.  Individual Rights of Trustee.
                    ---------------------------- 

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Notes and may otherwise deal with the Company, any Subsidiary of the
Company, or their respective Affiliates with the same rights it would have if it
were not Trustee.  Any Agent may do the same with like rights.  However, the
Trustee must comply with Sections 7.10 and 7.11.
<PAGE>
 
                                      -60-

     SECTION 7.04.  Trustee's Disclaimer.
                    -------------------- 

     The Trustee makes no representation as to the validity or adequacy of this
Indenture or the Notes, and it shall not be accountable for the Company's use of
the proceeds from the Notes, and it shall not be responsible for any statement
of the Company in this Indenture or the Notes other than the Trustee's
certificate of authentication.

     SECTION 7.05.  Notice of Default.
                    ----------------- 

     If a Default or an Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to each Holder notice of the
uncured Default or Event of Default within 90 days after such Default or Event
of Default becomes known to the Trustee.  Except in the case of a Default or an
Event of Default in payment of principal of, or interest on, any Note, the
Trustee may withhold the notice if and so long as its Board of Directors, the
executive committee of its Board of Directors or a committee of its directors
and/or Trust Officers in good faith determines that withholding the notice is in
the interest of the Holders.

     SECTION 7.06.  Reports by Trustee to Holders.
                    ----------------------------- 

     Within 60 days after each December 31, the Trustee shall, to the extent
that any of the events described in TIA (S) 313(a) occurred within the previous
twelve months, but not otherwise, mail to each Holder a brief report dated as of
such date that complies with TIA (S) 313(a).  The Trustee also shall comply with
TIA (S)(S) 313(b) and (c).

     A copy of each report at the time of its mailing to Holders shall be mailed
to the Company and filed with the SEC and each stock exchange, if any, on which
the Notes are listed.

     The Company shall promptly notify the Trustee in writing if the Notes
become listed on any stock exchange and the Trustee shall comply with TIA (S)
313(d).

     SECTION 7.07.  Compensation and Indemnity.
                    -------------------------- 

     The Company and the Subsidiary Guarantors shall pay to the Trustee from
time to time reasonable compensation for its services.  The Trustee's
compensation shall not be limited by any law on compensation of a trustee of an
express trust.  The Company and the Subsidiary Guarantors shall reimburse the
Trustee upon request for all reasonable out-of-pocket expenses incurred or made
by it in connection with the performance of its duties under this Indenture.
Such expenses shall include the reasonable fees and expenses of the Trustee's
agents and counsel.
<PAGE>
 
                                      -61-

     The Company and the Subsidiary Guarantors shall indemnify the Trustee and
its agents, employees, officers, directors and shareholders for, and hold it
harmless against, any loss, liability or expense incurred by it except for such
actions to the extent caused by any negligence, bad faith or willful misconduct
on its part, arising out of or in connection with the administration of this
trust including the reasonable costs and expenses of defending itself against
any claim or liability in connection with the exercise or performance of any of
its rights, powers or duties hereunder. The Trustee shall notify the Company
promptly of any claim asserted against the Trustee for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company and the Subsidiary Guarantors of their obligations hereunder. At the
Trustee's sole discretion, the Company shall defend the claim and the Trustee
shall provide reasonable cooperation and may participate at the Company's
expense in the defense. Alternatively, the Trustee may at its option have
separate counsel of its own choosing and the Company shall pay the reasonable
fees and expenses of such counsel; provided that the Company will not be
required to pay such fees and expenses if it assumes the Trustee's defense,
there is no conflict of interest between the Company and the Trustee in
connection with such defense as reasonably determined by the Trustee and no
Default or Event of Default has occurred and is continuing. The Company need not
pay for any settlement made without its written consent, which consent shall not
be unreasonably withheld. The Company need not reimburse any expense or
indemnify against any loss or liability to the extent incurred by the Trustee
through its negligence, bad faith or willful misconduct.

     To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a lien prior to the Notes on all assets or money held or
collected by the Trustee, in its capacity as Trustee, except assets or money
held in trust to pay principal of or interest on particular Notes.

     When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(d) or (e) occurs, such expenses and the
compensation for such services are intended to constitute expenses of
administration under any Bankruptcy Law.

     The obligations of the Company under this Section 7.07 and any lien arising
hereunder shall survive the resignation or removal of the Trustee, the discharge
of the Company's Obligations pursuant to Article Eight or the termination of
this Indenture.

     SECTION 7.08.  Replacement of Trustee.
                    ---------------------- 

     The Trustee may resign by so notifying the Company in writing, such
resignation to be effective upon the appointment of a successor Trustee.  The
Holders of a majority in principal amount of the outstanding Notes may remove
the Trustee by so notifying the Company and the Trustee in writing and may
appoint a successor Trustee with the Company's consent which consent shall not
be unreasonably withheld.  The Company may remove the Trustee if:
<PAGE>
 
                                      -62-

          (1) the Trustee fails to comply with Section 7.10;

          (2) the Trustee is adjudged bankrupt or insolvent;

          (3) a receiver or other public officer takes charge of the Trustee or
     its property; or

          (4) the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company shall notify each Holder of such event
and shall promptly appoint a successor Trustee.  Within one year after the
successor Trustee takes office, the Holders of a majority in principal amount of
the Notes may appoint a successor Trustee to replace the successor Trustee
appointed by the Company.

     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company.  Immediately after that, the
retiring Trustee shall transfer all property held by it as Trustee to the
successor Trustee, subject to the lien provided in Section 7.07, the resignation
or removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture.  A successor Trustee shall mail notice of its succession to each
Holder.

     If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of at least 10% in principal amount of the outstanding Notes may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

     If the Trustee fails to comply with Section 7.10, any Holder may petition
any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee.

     Notwithstanding replacement of the Trustee pursuant to this Section 7.08,
the Company's obligations under Section 7.07 shall continue for the benefit of
the retiring Trustee.

     SECTION 7.09.  Successor Trustee by Merger, Etc.
                    -------------------------------- 

     If the Trustee consolidates with, merges or converts into, or transfers all
or substantially all of its corporate trust business to, another corporation or
national banking  association, the resulting, surviving or transferee
corporation without any further act shall, if such resulting, surviving or
transferee corporation is otherwise eligible hereunder, be the successor
Trustee; provided that such corporation shall be otherwise qualified and
eligible under this Article Seven.

TIA (S)(S) 310(a)(1), (2) and (5).  The Trustee (or, in the case of a
corporation included in a bank holding company system, the related bank holding
company) shall have a combined capital and surplus of at least $100 million as
set forth in its most recent published annual report of condition.  In addition,
if the Trustee is a corporation included in a bank holding company system, the
Trustee, independently of such bank holding company, shall meet the capital
requirements of TIA (S) 310(a)(2).  The Trustee shall comply with TIA (S)
310(b); provided, however, that there shall be excluded from the operation of
TIA (S) 310(b)(1) any indenture or indentures under which other securities, or
certificates of interest or participation in other securities, of the Company
are outstanding, if the requirements for such exclusion set forth in TIA (S)
310(b)(1) are met.

     SECTION 7.11.  Preferential Collection of Claims
                    Against Company.
                    ----------------------------------

     The Trustee shall comply with TIA (S) 311(a), excluding any creditor
relationship listed in TIA (S) 311(b).  A Trustee who has resigned or been
removed shall be subject to TIA (S) 311(a) to the extent indicated therein.

                    ---------------------------------------- 

     In connection with the satisfaction and discharge of this Indenture all
moneys then held by any paying agent under the provisions of this Indenture
shall, upon demand of the Company, be repaid to it or paid to the Trustee and
thereupon such paying agent shall be released from all further liability with
respect to such moneys.

     SECTION 8.06.  Return of Moneys Held by Trustee and Paying
                    Agent Unclaimed for Three Years.
                    -----------------------------------------------

     Any moneys deposited with or paid to the Trustee or any paying agent for
the payment of the principal of or interest on any Note and not applied but
remaining unclaimed for three years after the date upon which such principal or
interest shall have become due and payable, shall, upon the written request of
the Company and unless otherwise required by mandatory
<PAGE>
 
                                      -68-

provisions of applicable escheat or abandoned or unclaimed property law, be
repaid to the Company by the Trustee or such paying agent, and the holder of
such Note shall, unless otherwise required by mandatory provisions of applicable
escheat or abandoned or unclaimed property laws, thereafter look only to the
Company for any payment which such holder may be entitled to collect, and all
liability of the Trustee or any paying agent with respect to such moneys shall
thereupon cease.

     SECTION 8.07.  Reinstatement.
                    ------------- 

     If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or
U.S. Government Obligations in accordance with Article Eight by reason of any
legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's and each Subsidiary Guarantor's obligations under
this Indenture and the Notes shall be revived and reinstated as though no
deposit had occurred pursuant to Article Eight until such time as the Trustee or
Paying Agent is permitted to apply all such U.S. Legal Tender or U.S. Government
Obligations in accordance with Article Eight; provided that if the Company or
any Subsidiary Guarantor, as the case may be, has made any payment of interest
on or principal of any Notes because of the reinstatement of its obligations,
the Company or any Subsidiary Guarantor, as the case may be, shall be subrogated
to the rights of the Holders of such Notes to receive such payment from the U.S.
Legal Tender or U.S. Government Obligations held by the Trustee or Paying Agent.

                                  ARTICLE NINE

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS

     SECTION 9.01.  Without Consent of Holders.
                    -------------------------- 

     The Company, when authorized by a Board Resolution, and the Trustee,
together, may amend or supplement this Indenture, the Notes or any Guarantee
without notice to or consent of any Holder:

          (1) to cure any ambiguity, defect or inconsistency; provided that such
     amendment or supplement does not adversely affect the rights of any Holder;

          (2)  to comply with Article Five;

          (3) to provide for uncertificated Notes in addition to or in place of
     certificated Notes;
<PAGE>
 
                                      -69-

          (4) to comply with any requirements of the SEC in order to effect or
     maintain the qualification of this Indenture under the TIA; or

          (5) to make any change that would provide any additional benefit or
     rights to the Holders or that does not adversely affect the rights of any
     Holder;

provided that the Company has delivered to the Trustee an Opinion of Counsel and
an Officers' Certificate stating that such amendment or supplement complies with
the provisions of this Section 9.01.

     SECTION 9.02.  With Consent of Holders.
                    ----------------------- 

     Subject to Section 6.07, the Company, when authorized by a Board
Resolution, and the Trustee, together, with the written consent of the Holder or
Holders of at least a majority in aggregate principal amount of the outstanding
Notes, may amend or supplement this Indenture, the Notes or any Guarantee
without notice to any other Holders.  Subject to Section 6.07, the Holder or
Holders of a majority in aggregate principal amount of the outstanding Notes may
waive compliance by the Company with any provision of this Indenture or the
Notes without notice to any other Holder.  No amendment, supplement or waiver,
including a waiver pursuant to Section 6.04, shall, without the consent of each
Holder of each Note affected thereby:

          (1) change the principal amount of Notes whose Holders must consent to
     an amendment, supplement or waiver of any provision of this Indenture, the
     Notes or any Guarantee;

          (2) reduce the rate of or change or have the effect of extending the
     time for payment of interest, including defaulted interest, on any Notes;

          (3) reduce the principal amount of any Note;

          (4) extend the Maturity Date of any Note, or alter the redemption
     provisions contained in Article Three or in Paragraph 6 of the Notes or the
     repurchase provisions contained in Sections 4.15 and 4.16 in a manner
     adverse to any Holder (except that provisions affecting the requirement to
     repurchase the Notes following a Change of Control may be amended by the
     Company, the Trustee and the Holders of not less than 75% in aggregate
     principal amount of Notes then outstanding);

          (5) make any changes in provisions concerning waivers of Defaults or
     Events of Default by Holders of the Notes or the rights of Holders to
     recover the principal of, interest on, premium, if any, or redemption
     payment with respect to, any Note;
<PAGE>
 
                                      -70-

          (6) make the principal of, or the interest on, any Note payable with
     anything or in any manner other than as provided for in this Indenture and
     the Notes as in effect on the date hereof; or

          (7) make any change to the subordination provisions of this Indenture
     and the Note in a manner adverse to the Holders.

     It shall not be necessary for the consent of the Holders under this Section
to approve the particular form of any proposed amendment, supplement or waiver,
but it shall be sufficient if such consent approves the substance thereof.

     After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company shall mail to the Holders affected thereby a notice
briefly describing the amendment, supplement or waiver.  Any failure of the
Company to mail such notice, or any defect therein, shall not, however, in any
way impair or affect the validity of any such supplemental indenture.

     SECTION 9.03.  Effect on Senior Debt.
                    --------------------- 

     No amendment, supplement or waiver of this Indenture shall adversely affect
the rights of any holder of Senior Debt or Guarantor Senior Debt, if any
(including their rights under Article Ten or Eleven), without the consent of
such holder.

     SECTION 9.04.  Compliance with TIA.
                    ------------------- 

     Every amendment, waiver or supplement of this Indenture or the Notes shall
comply with the TIA as then in effect.

     SECTION 9.05.  Revocation and Effect of Consents.
                    --------------------------------- 

     Until an amendment, waiver or supplement becomes effective, a consent to it
by a Holder is a continuing consent  by the Holder and every subsequent Holder
of a Note or portion of a Note that evidences the same debt as the consenting
Holder's Note, even if notation of the consent is not made on any Note.  Subject
to the following paragraph, any such Holder or subsequent Holder may revoke the
consent as to such Holder's Note or portion of such Note by written notice to
the Trustee or the Company received before the date on which the Trustee
receives an Officers' Certificate certifying that the Holders of the requisite
principal amount of Notes have consented (and not theretofore revoked such
consent) to the amendment, supplement or waiver.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver, which
<PAGE>
 
                                      -71-

record date shall be at least 30 days prior to the first solicitation of such
consent.  If a record date is fixed, then notwithstanding the last sentence of
the immediately preceding paragraph, those Persons who were Holders at such
record date (or their duly designated proxies), and only those Persons, shall be
entitled to revoke any consent previously given, whether or not such Persons
continue to be Holders after such record date.  No such consent shall be valid
or effective for more than 90 days after such record date.

     After an amendment, supplement or waiver becomes effective, it shall bind
every Holder, unless it makes a change described in any of clauses (1) through
(7) of Section 9.02, in which case, the amendment, supplement or waiver shall
bind only each Holder of a Note who has consented to it and every subsequent
Holder of a Note or portion of a Note that evidences the same debt as the
consenting Holder's Note; provided that any such waiver shall not impair or
affect the right of any Holder to receive payment of principal of and interest
on a Note, on or after the respective due dates expressed in such Note, or to
bring suit for the enforcement of any such payment on or after such respective
dates without the consent of such Holder.

     SECTION 9.06.  Notation on or Exchange of Notes.
                    -------------------------------- 

     If an amendment, supplement or waiver changes the terms of a Note, the
Trustee may, at the written direction of the Company, require the Holder of the
Note to deliver it to the Trustee.  The Trustee at the written direction of the
Company may place an appropriate notation on the Note about the changed terms
and return it to the Holder.  Alternatively, if the Company or the Trustee so
determines, the Company in exchange for the Note shall issue and the Trustee
shall  authenticate a new Note that reflects the changed terms.  Any such
notation or exchange shall be made at the sole cost and expense of the Company.
Failure to make the appropriate notation or issue a new Note shall not affect
the validity and effect of such amendment, supplement or waiver.

     SECTION 9.07.  Trustee To Sign Amendments, Etc.
                    ------------------------------- 

     The Trustee shall execute any amendment, supplement or waiver authorized
pursuant to this Article Nine; provided that the Trustee may, but shall not be
obligated to, execute any such amendment, supplement or waiver which affects the
Trustee's own rights, duties or immunities under this Indenture.  The Trustee
shall be entitled to receive, if requested, an indemnity reasonably satisfactory
to it and to receive, and shall be fully protected in relying upon, an Opinion
of Counsel and an Officers' Certificate each stating that the execution of any
amendment, supplement or waiver authorized pursuant to this Article Nine is
authorized or permitted by this Indenture.  Such Opinion of Counsel shall not be
an expense of the Trustee.

                                 SUBORDINATION

     SECTION 10.01. Notes Subordinated to Senior Debt.
                    --------------------------------- 

     The Company covenants and agrees and the Trustee and each Holder of the
Notes, by its acceptance thereof, likewise covenants and agrees, that all Notes
shall be issued subject to the provisions of this Article Ten; and the Trustee
and each person holding any Note, whether upon original issue or upon transfer,
assignment or exchange thereof, accepts and agrees that the payment of all
Obligations on the Notes by the Company shall, to the extent and in the manner
herein set forth, be subordinated and junior in right of payment to the prior
payment in full in cash or Cash Equivalents of all Obligations on the Senior
Debt (including, for all purposes of this Article Ten, the cash
collateralization in full of all outstanding letters of credit constituting
Senior Debt); that the subordination is for the benefit of, and shall be
enforceable directly by, the holders of Senior Debt, and that each holder of
Senior Debt whether now outstanding or hereinafter created, incurred, assumed or
guaranteed shall be deemed to have acquired Senior Debt in reliance upon the
covenants and provisions contained in this Indenture and the Notes.


     SECTION 10.02. No Payment on Notes in Certain
                    Circumstances.
                    -----------------------------------

     (a) No direct or indirect payment (excluding any payment or distribution of
Permitted Junior Securities and excluding any payment (a "Defeasance Trust
                                                          ----------------

Trust") 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, a Change of Control Offer 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
 -----------------------
<PAGE>
 
                                      -73-

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
this 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.

     (b) In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee or any Holder when such payment is prohibited by Section
10.02(a), such payment shall be held in trust for the benefit of, and shall be
paid over or delivered to, the holders of Senior Debt (pro rata to such holders
on the basis of the respective amount of Senior Debt held by such holders) or
their respective Representatives, as their respective interests may appear.  The
Trustee shall be entitled to rely on information regarding amounts then due and
owing on the Senior Debt, if any, received from the holders of Senior Debt (or
their Representatives) or, if such information is not received from such holders
or their Representatives, from the Company and only amounts included in the
information provided to the Trustee shall be paid to the holders of Senior Debt.

     Nothing contained in this Article Ten shall limit the right of the Trustee
or the Holders of Notes to take any action to accelerate the maturity of the
Notes pursuant to Section 6.02 or to pursue any rights or remedies hereunder;
provided that all Senior Debt thereafter due or declared to be due shall first
be paid in full in cash or Cash Equivalents before the Holders are entitled to
receive any payment of any kind or character with respect to the Obligations on
the Notes.

     SECTION 10.03.  Payment Over of Proceeds Upon
                    Dissolution, Etc.
                    -------------------------------------

     (a) 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
Defeasance Trust Payment, 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 this 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 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.

     (b) To the extent any payment of Senior Debt (whether by or on behalf of
the Company, as proceeds of security or enforcement of any right of setoff or
otherwise) is declared to be fraudulent or preferential, set aside or required
to be paid to any receiver, trustee in

                                      -75-

bankruptcy, liquidating trustee, agent or other similar person under any
bankruptcy, insolvency, receivership, fraudulent conveyance or similar law,
then, if such payment is recovered by, or paid over to, such receiver, trustee
in bankruptcy, liquidating trustee, agent or other similar person, the Senior
Debt or part thereof originally intended to be satisfied shall be deemed to be
reinstated and outstanding as if such payment had not occurred.

     (c) In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, shall be received by any Holder when such payment or
distribution is prohibited by Section 10.03(a), such payment  or distribution
shall be held in trust for the benefit of, and shall be paid over or delivered
to, the holders of Senior Debt (pro rata to such holders on the basis of the
respective amount of Senior Debt held by such holders) or their respective
Representatives, or to the trustee or trustees under any indenture pursuant to
which any of such Senior Debt may have been issued, as their respective
interests may appear, for application to the payment of Senior Debt remaining
unpaid until all such Senior Debt has been paid in full in cash or Cash
Equivalents, after giving effect to any concurrent payment, distribution or
provision therefor to or for the holders of such Senior Debt.

     SECTION 10.04. Payments May Be Paid Prior to
                    Dissolution.
                    ------------------------------------

     Nothing contained in this Article Ten or elsewhere in this Indenture shall
prevent (i) the Company, except under the conditions set forth in Sections 10.02
and 10.03, from making payments at any time for the purpose of making payments
of principal of and interest on the Notes, or from depositing with the Trustee
any moneys for such payments, or (ii) in the absence of actual knowledge of the
Trustee that a given payment would be prohibited by Section 10.02 or 10.03, the
application by the Trustee of any moneys deposited with it for the purpose of
making such payments of principal of and interest on the Notes to the Holders
entitled thereto unless at least one Business Day prior to the date upon which
such payment would otherwise become due and payable, the Trustee shall have
received the written notice provided for in Section 10.02(a) or in Section 10.07
(provided that, notwithstanding the foregoing, such application shall otherwise
be subject to the provisions of the first sentence of Section 10.02(a) and
Section 10.03).  The Company shall give prompt written notice to the Trustee of
any dissolution, winding-up, liquidation or reorganization of the Company.

     SECTION 10.05. Subrogation.
                    ----------- 

     Subject to the payment in full in cash or Cash Equivalents of all Senior
Debt, the Holders of the Notes shall be subrogated to the rights of the holders
of Senior Debt to receive payments or distributions of cash, property or
securities of the Company applicable to the Senior Debt until the  Notes shall
be paid in full; and, for the purposes of such subrogation, no such payments or
<PAGE>
 
                                      -76-

distributions to the holders of the Senior Debt by or on behalf of the Company
or by or on behalf of the Holders by virtue of this Article Ten which otherwise
would have been made to the Holders shall, as between the Company and the
Holders of the Notes, be deemed to be a payment by the Company to or on account
of the Senior Debt, it being understood that the provisions of this Article Ten
are and are intended solely for the purpose of defining the relative rights of
the Holders of the Notes, on the one hand, and the holders of the Senior Debt,
on the other hand.

     If any payment or distribution to which the Holders would otherwise have
been entitled but for the provisions of this Article Ten shall have been
applied, pursuant to the provisions of this Article Ten, to the payment of
amounts payable under the Senior Debt, then the Holders shall be entitled to
receive from the holders of such Senior Debt any payments or distributions
received by such holders of Senior Debt in excess of the amount sufficient to
pay all amounts payable under or in respect of the Senior Debt in full in cash
or Cash Equivalents.

     SECTION 10.06. Obligations of the Company
                    Unconditional.
                    ------------------------------

     Nothing any contained in this Article Ten or elsewhere in this Indenture or
in the Notes is intended to or shall impair, as among the Company, its creditors
other than the holders of Senior Debt, and the Holders of the Notes, the
obligation of the Company, which is absolute and unconditional, to pay to the
Holders of the Notes the principal of and any interest on the Notes as and when
the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of the Holders of the Notes and
creditors of the Company other than the holders of the Senior Debt, nor shall
anything herein or therein prevent the Holder of any Note or the Trustee on its
behalf from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture, subject to the rights, if any, in respect of cash,
property or securities of the Company received upon the exercise of any such
remedy.

     SECTION 10.07. Notice to Trustee.
                    ----------------- 

     The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of  the Notes pursuant to the provisions of this Article Ten.
Regardless of anything to the contrary contained in this Article Ten or
elsewhere in this Indenture, the Trustee shall not be charged with knowledge of
the existence of any default or event of default with respect to any Senior Debt
or of any other facts which would prohibit the making of any payment to or by
the Trustee unless and until the Trustee shall have received notice in writing
from the Company, or from a holder of Senior Debt or a Representative therefor,
and, prior to the receipt of any such written notice, the Trustee shall be
entitled to assume (in the absence of actual knowledge to the contrary) that no
such facts exist.
<PAGE>
 
                                      -77-

     In the event that the Trustee determines in good faith that any evidence is
required with respect to the right of any person as a holder of Senior Debt to
participate in any payment or distribution pursuant to this Article Ten, the
Trustee may request such person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amounts of Senior Debt held by such
person, the extent to which such person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
person under this Article Ten and, if such evidence is not furnished, the
Trustee may defer any payment to such person pending judicial determination as
to the right of such person to receive such payment.

     SECTION 10.08. Reliance on Judicial Order or
                    Certificate of Liquidating Agent.
                    -------------------------------- 

     Upon any payment or distribution of assets of the Company referred to in
this Article Ten, the Trustee, subject to the provisions of Article Seven
hereof, and the Holders of the Notes shall be entitled to rely upon any order or
decree made by any court of competent jurisdiction in which bankruptcy,
dissolution, winding-up, liquidation or reorganization proceedings are pending,
or upon certificate of the receiver, trustee in bankruptcy, liquidating trustee,
agent or other person making such payment or distribution, delivered to the
Trustee or the holders of the Notes, for the purpose of ascertaining the Persons
entitled to participate in such distribution, the holders of the Senior Debt and
other Indebtedness of the Company, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article Ten.

     SECTION 10.09. Trustee's Relation to Senior Debt.
                    --------------------------------- 

     The Trustee and any agent of the Company or the Trustee shall be entitled
to all the rights set forth in this Article Ten with respect to any Senior Debt
which may at any time be held by it in its individual or any other capacity to
the same extent as any other holder of Senior Debt and nothing in this Indenture
shall deprive the Trustee or any such agent of any of its rights as such holder.

     With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article Ten, and no implied covenants or
obligations with respect to the holders of Senior Debt shall be read into this
Indenture against the Trustee.  The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Debt and shall not be liable to any such
holders if the Trustee shall pay over or distribute to or on behalf of Holders
or the Company or any other person money or assets to which any holders of
Senior Debt shall be entitled by virtue of this Article, except if such payment
is made as a result of willful misconduct or gross negligence of the Trustee.
<PAGE>
 
                                      -78-

     Whenever a distribution is to be made or a notice given to holders or
owners of Senior Debt, the distribution may be made and the notice given to
their Representatives, if any.

     SECTION 10.10. Subordination Rights Not Impaired by
                    Acts or Omissions of the Company or
                    Holders of Senior Debt.
                    ----------------------------------------

     No right of any present or future holders of any Senior Debt to enforce
subordination as provided herein shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the Company with the terms of this Indenture, regardless of any knowledge
thereof which any such holder may have or otherwise be charged with.

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee, without incurring responsibility to the
Trustee or the Holders of the Notes and without impairing or releasing the
subordination provided in this Article Ten or the  obligations hereunder of the
Holders of the Notes to the holders of the Senior Debt, do any one or more of
the following:  (i) change the manner, place or terms of payment or extend the
time of payment of, or renew or alter, Senior Debt, or otherwise amend or
supplement in any manner Senior Debt, or any instrument evidencing the same or
any agreement under which Senior Debt is outstanding; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Debt; (iii) release any Person liable in any manner for the
payment or collection of Senior Debt; and (iv) exercise or refrain from
exercising any rights against the Company and any other Person.

     SECTION 10.11. Noteholders Authorize Trustee To
                    Effectuate Subordination of Notes.
                    ----------------------------------

     Each Holder of Notes by its acceptance of them authorizes and expressly
directs the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate, as between the holders of Senior Debt and the Holders
of Notes, the subordination provided in this Article Ten, and appoints the
Trustee its attorney-in-fact for such purposes, including, in the event of any
dissolution, winding-up, liquidation or reorganization of the Company (whether
in bankruptcy, insolvency, receivership, reorganization or similar proceedings
or upon an assignment for the benefit of creditors or otherwise) tending towards
liquidation of the business as assets of the Company, the filing of a claim for
the unpaid balance of its or his Notes and accrued interest in the form required
in those proceedings.
<PAGE>
 
                                      -79-


     If the Trustee does not file a proper claim or proof of debt in the form
required in such proceeding prior to 30 days before the expiration of the time
to file such claim or claims, then the holders of the Senior Debt or their
Representative are or is hereby authorized to have the right to file and are or
is hereby authorized to file an appropriate claim for and on behalf of the
Holders of said Notes. Nothing herein contained shall be deemed to authorize the
Trustee or the holders of Senior Debt or their Representative to authorize or
consent to or accept or adopt on behalf of any Holders any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee or the holders of
Senior Debt or their Representative to vote in respect of the claim of any
Holder in any such proceeding.

     SECTION 10.12. This Article Ten Not To Prevent
                    Events of Default.
                    ------------------------------------

     The failure to make a payment on account of principal of or interest on the
Notes by reason of any provision of this Article Ten will not be construed as
preventing the occurrence of an Event of Default.

     SECTION 10.13. Trustee's Compensation Not Prejudiced.
                    ------------------------------------- 

     Nothing in this Article Ten will apply to amounts due to the Trustee
pursuant to other sections in this Indenture.

                                 ARTICLE ELEVEN

                                   GUARANTEES

     SECTION 11.01. Unconditional Guarantee.
                    ----------------------- 

     Each Subsidiary Guarantor hereby unconditionally, jointly and severally,
guarantees (such guarantee to be referred to herein as the "Guarantee") to each
                                                            ---------          
Holder of a Note authenticated and delivered by the Trustee and to the Trustee
and its successors and assigns, the Notes or the obligations of the Company
hereunder or thereunder, that:  (i) the principal of and interest on the Notes
will be promptly paid in full when due, subject to any applicable grace period,
whether at maturity, by acceleration or otherwise and interest on the overdue
principal, if any, and interest on any interest, to the extent lawful, of the
Notes and all other obligations of the Company to the Holders or the Trustee
hereunder or thereunder will be promptly paid in full, and the due and punctual
performance of all other obligations of the Company to the Holders or the
Trustee, all in accordance with the terms hereof and thereof; and (ii) in case
of any extension of time of payment or renewal of any Notes or of any such other
obligations, the same will be promptly
<PAGE>
 
                                      -80-

paid in full when due in accordance with the terms of the extension or renewal,
subject to any applicable grace period, whether at stated maturity, by
acceleration or otherwise, subject, however, in the case of clauses (i) and (ii)
above, to the limitations set forth in Section 11.05. Each Subsidiary Guarantor
hereby agrees that its Obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this
Indenture, the absence of any action to enforce the same, any waiver or consent
by any Holder of the Notes with respect to any provisions hereof or thereof, the
recovery of any judgment against the Company, any action to enforce the same or
any other circumstances which might otherwise constitute a legal or equitable
discharge or defense of a guarantor. Each Subsidiary Guarantor hereby waives
diligence, presentment, demand of payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and covenants that this Guarantee will not be discharged except by complete
performance of the obligations contained in the Notes, this Indenture and in
this Guarantee. If any Noteholder or the Trustee is required by any court or
otherwise to return to the Company, any Subsidiary Guarantor, or any custodian,
trustee, liquidator or other similar official acting in relation to the Company
or any Subsidiary Guarantor, any amount paid by the Company or any Subsidiary
Guarantor to the Trustee or such Noteholder, this Guarantee, to the extent
theretofore discharged, shall be reinstated in full force and effect as to such
amount only. Each Subsidiary Guarantor further agrees that, as between each
Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on the
other hand, (x) the maturity of the Obligations guaranteed hereby may be
accelerated as provided in Article Six for the purposes of this Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Obligations guaranteed hereby, and (y) in the
event of any acceleration of such obligations as provided in Article Six, such
Obligations (whether or not due and payable) shall forthwith become due and
payable by each Subsidiary Guarantor for the purpose of this Guarantee.

     SECTION 11.02. Subordination of Guarantee.
                    -------------------------- 

     Each Subsidiary Guarantor agrees, and each Holder by accepting a Guarantee
agrees, that all Obligations owed under and in respect of such Guarantees are
subordinated in right of payment, to the extent and in the manner provided in
this Article Eleven, to the prior indefeasible payment in full in cash or Cash
Equivalents, of all Guarantor Senior Debt of such Subsidiary Guarantor, and that
the subordination of the Guarantees pursuant to this Article Eleven is for the
benefit of all holders of all Guarantor Senior Debt of such Subsidiary
Guarantor, whether outstanding on the Issue Date or issued thereafter.

     SECTION 11.03. Severability.
                    ------------ 
<PAGE>
 
                                      -81-

     In case any provision of this Guarantee shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.


     SECTION 11.04.  Release of a Subsidiary Guarantor.
                     --------------------------------- 

     Upon (i) a defeasance of the Notes in accordance with the terms of Section
8.02 or 8.03, or (ii) subject to the requirements of Section 5.01, 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 Section 4.16 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 Section 4.16 and within the time
limits specified by Section 4.16, 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 this Indenture and the Notes.  Any Subsidiary
Guarantor not so released remains liable for the full amount of principal of and
interest on the Notes as provided in this Article Eleven.

     SECTION 11.05. Limitation of Subsidiary Guarantor's
                    Liability.
                    -------------------------------------------

     Each Subsidiary Guarantor and by its acceptance hereof each Holder hereby
confirms that it is the intention of all such parties that the guarantee by such
Subsidiary Guarantor pursuant to its Guarantee not constitute a fraudulent
transfer or conveyance for purposes of the Bankruptcy Law, the Uniform
Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar
Federal or state law.  To effectuate the foregoing intention, the Holders and
such Subsidiary Guarantor hereby irrevocably agree that the Obligations of such
Subsidiary Guarantor under its Guarantee shall be limited to the maximum amount
as will, 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 Guarantee or
pursuant to Section 11.07, result in the Obligations of such Subsidiary
Guarantor under its Guarantee not constituting such fraudulent transfer or
conveyance.

     SECTION 11.06. Subsidiary Guarantors May Consolidate,
                    Etc., on Certain Terms.
                    -------------------------------------------
<PAGE>
 
                                      -82-

     (a) Nothing contained in this Indenture or in any of the Notes shall
prevent any consolidation or merger of a Subsidiary Guarantor with or into the
Company or another Subsidiary Guarantor or shall prevent any sale or conveyance
of the assets of a Subsidiary Guarantor to the Company or another Subsidiary
Guarantor. Upon any such consolidation, merger, sale or conveyance, the
Guarantee given by such Subsidiary Guarantor shall no longer have any force or
effect.

     (b) Except as set forth in Article Four, nothing contained in this
Indenture or in any of the Notes shall prevent any consolidation or merger of a
Subsidiary Guarantor with or into a corporation or corporations other than the
Company or another Subsidiary Guarantor (whether or not affiliated with the
Subsidiary Guarantor), or successive consolidations or mergers in which a
Subsidiary Guarantor or its successor or successors shall be a party or parties,
or shall prevent any sale or conveyance of all or substantially all of the
assets of a Subsidiary Guarantor to a corporation other than the Company or
another Subsidiary Guarantor (whether or not affiliated with the Subsidiary
Guarantor); provided, however, that, subject to Sections 11.04 and 11.06(a),
either (x) the transaction is an Asset Disposition consummated in accordance
with Section 4.16, or (y) (i) immediately after such transaction, and giving
effect thereto, no Default or Event of Default shall have occurred as a result
of such transaction and be continuing, and (ii) each Subsidiary Guarantor hereby
covenants and agrees that, upon any such consolidation, merger, sale or
conveyance, the Guarantee of such Subsidiary Guarantor set forth in this Article
Eleven, and the due and punctual performance and observance of all of the
covenants and conditions of this Indenture to be performed by such Subsidiary
Guarantor, shall be expressly assumed (in the event that the Subsidiary
Guarantor is not the surviving corporation in such transaction), by supplemental
indenture satisfactory in form to the Trustee, executed and delivered to the
Trustee, together with an Officers' Certificate of the Company and an Opinion of
Counsel stating that the transaction and such supplemental indenture comply with
this Indenture, by the corporation formed by such consolidation, or into which
the Subsidiary Guarantor shall have merged, or by the corporation that shall
have acquired such property.  In the case of any such consolidation, merger,
sale or conveyance that is not an Asset Disposition consummated in accordance
with Section 4.16, upon the assumption by the successor corporation, by
supplemental indenture executed and delivered to the Trustee and satisfactory in
form to the Trustee of the due and punctual performance of all of the covenants
and conditions of this Indenture to be performed by the Subsidiary Guarantor,
such successor corporation shall succeed to and be substituted for the
Subsidiary Guarantor with the same effect as if it had been named herein as a
Subsidiary Guarantor.

     SECTION 11.07. Contribution.
                    ------------ 

     In order to provide for just and equitable contribution among the
Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the
event any payment or distribution is made by any Subsidiary Guarantor (a
                                                                        
"Funding Guarantor") under this Guarantee, such Funding
- ------------------                                                        
<PAGE>
 
                                      -83-



Guarantor shall be entitled to a contribution from all other Subsidiary
Guarantors in a pro rata amount based on the Adjusted Net Assets of each
Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages
and expenses incurred by that Funding Guarantor in discharging the Company's
obligations with respect to the Notes or any other Subsidiary Guarantor's
Obligations with respect to this Guarantee.

     SECTION 11.08. Waiver of Subrogation.
                    --------------------- 

     Each Subsidiary Guarantor hereby irrevocably waives any claim or other
rights which it may now or hereafter acquire against the Company that arise from
the existence, payment, performance or enforcement of such Subsidiary
Guarantor's Obligations under this Guarantee and this Indenture, including,
without limitation, any right of subrogation, reimbursement, exoneration,
indemnification, and any right to participate in any claim or remedy of any
Holder of Notes against the Company, whether or not such claim, remedy or right
arises in equity, or under contract, statute or common law, including, without
limitation, the right to take or receive from the Company, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or security on account of such claim or other rights.  If any amount
shall be paid to any Subsidiary Guarantor in violation of the preceding sentence
and the Notes shall not have been paid in full, such amount shall have been
deemed to have been paid to such Subsidiary Guarantor for the benefit of, and
held in trust for the benefit of, the Holders of the Notes, and shall forthwith
be paid to the Trustee for the benefit of such Holders to be credited and
applied upon the Notes, whether matured or unmatured, in accordance with the
terms of this Indenture.  Each Subsidiary Guarantor acknowledges that it will
receive direct and indirect benefits from the financing arrangements
contemplated by this Indenture and that the waiver set forth in this Section
11.08 is knowingly made in contemplation of such benefits.

     SECTION 11.09. Execution of Guarantee; Additional Subsidiary Guarantors.
                    -------------------------------------------------------- 

     (a) To evidence their guarantee to the Noteholders specified in Section
11.01, the Subsidiary Guarantors hereby agree to execute the Guarantee in
substantially the form of  Exhibit A recited to be endorsed on each Note ordered
to be authenticated and delivered by the Trustee.  Each Subsidiary Guarantor
hereby agrees that its Guarantee set forth in Section 11.01 shall remain in full
force and effect notwithstanding any failure to endorse on each Note a notation
of such Guarantee.  Each such Guarantee shall be signed on behalf of each
Subsidiary Guarantor by one Officer (each of whom shall, in each case, have been
duly authorized by all requisite corporate actions) prior to the authentication
of the Note on which it is endorsed, and the delivery of such Note by the
Trustee, after the authentication thereof hereunder, shall constitute due
delivery of such Guarantee on behalf of such Subsidiary Guarantor.  Such
signatures upon the Guarantee may be by manual or facsimile signature of such
officers and may be imprinted or otherwise reproduced on the Guarantee, and in
case any such officer who shall have signed the Guarantee shall cease to be such
officer before the Note on which such Guarantee
<PAGE>
 
                                      -84-

is endorsed shall have been authenticated and delivered by the Trustee or
disposed of by the Company, such Note nevertheless may be authenticated and
delivered or disposed of as though the person who signed the Guarantee had not
ceased to be such officer of the Subsidiary Guarantor.

     (b) The Company shall cause each Subsidiary required to issue a Subsidiary
Guarantee after the Issue Date 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 this Indenture and thereby
unconditionally guarantee all of the Company's Obligations under the Notes and
this 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 this Indenture.

     SECTION 11.10. No Payment on Guarantees in Certain
                    Circumstances.
                    ------------------------------------------

     (a) 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 any
Subsidiary Guarantor pursuant to its Guarantee 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, a Change of Control Offer 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 guaranteed by such Subsidiary Guarantor (which guarantee
constitutes Guarantor Senior Debt of such Subsidiary Guarantor), 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 "Guarantor 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
<PAGE>
 
                                      -85-

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 such Subsidiary Guarantor pursuant to its Guarantee 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 "Guarantor 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 this Indenture or the Notes to the contrary, (x) in
no event will a Guarantor Payment Blockage Period extend beyond 179 days from
the date the Guarantor Payment Blockage Notice in respect thereof was given, and
(y) not more than one Guarantor 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
Guarantor Payment Blockage Period with respect to the Designated Senior Debt
initiating such Guarantor Payment Blockage Period (to the extent the holder of
Designated Senior Debt, or trustee or agent, giving notice commencing such
Guarantor 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 Guarantor 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.

     (b) In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee or any Holder when such payment is prohibited by Section
11.10(a), such payment shall be held in trust for the benefit of, shall be paid
over or delivered to, the holders of Guarantor Senior Debt (pro rata to such
holders on the basis of the respective amount of Guarantor Senior Debt held by
such holders) or their respective Representatives, as their respective interests
may appear.  The Trustee shall be entitled to rely on information regarding
amounts then due and owing on  the Guarantor Senior Debt, if any, received from
the holders of Guarantor Senior Debt (or their Representatives) or, if such
information is not received from such holders or their Representatives, from
such Subsidiary Guarantor and only amounts included in the information provided
to the Trustee shall be paid to the holders of Guarantor Senior Debt.

     Nothing contained in this Article Eleven shall limit the right of the
Trustee or the Holders of Notes to take any action to accelerate the maturity of
the Notes pursuant to Section 6.02 or to pursue any rights or remedies
hereunder; provided that all Guarantor Senior Debt thereafter due or declared to
be due shall first be paid in full in cash or Cash Equivalents before the
Holders are entitled to receive any payment of any kind or character with
respect to the Obligations on the Notes or on account of any Subsidiary
Guarantor's Guarantee.

     SECTION 11.11. Payment Over of Proceeds Upon
                    Dissolution, Etc.
                    ------------------------------------
<PAGE>
 
                                      -86-

     (a) Upon any payment or distribution of assets or securities of any
Subsidiary Guarantor 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, upon any dissolution or winding-up
or total liquidation or reorganization of such Subsidiary Guarantor, whether
voluntary or involuntary or in bankruptcy, insolvency, receivership or other
proceedings, all Guarantor 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 such Subsidiary Guarantor of the principal
of or interest or liquidated damages on the Notes pursuant to its Guarantee, or
any payment by the such Subsidiary Guarantor to acquire any of the Notes for
cash, property or securities, or any distribution by such Subsidiary Guarantor
with respect to its Guarantee of 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, such Subsidiary Guarantor of the principal of or interest or
liquidated damages on the Notes pursuant to its Guarantee upon any such
dissolution or winding-up or total liquidation or reorganization, any payment or
distribution of assets or securities of such Subsidiary Guarantor 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 this Indenture, shall be
made by such Subsidiary Guarantor or by any receiver, trustee in bankruptcy,
liquidation trustee, agent or other Person making such payment or distribution,
directly to the holders of the Guarantor Senior Debt (pro rata to such holders
on the basis of the respective amounts of Guarantor 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 Guarantor 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 Guarantor Senior Debt. In the event that,
notwithstanding the foregoing, the Trustee or any holder of Notes receives any
payment or distribution of assets of such Subsidiary Guarantor of any kind,
whether in cash, property or securities, including, without limitation, by way
of set-off or otherwise, in respect of such Subsidiary Guarantor's Guarantee of
the Notes before all Guarantor Senior Debt of such Subsidiary Guarantor 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 Guarantor Senior Debt and will be
immediately paid on or delivered to the holders of Guarantor Senior Debt or
their representative or representatives to the extent necessary to make payment
in full in cash of all Guarantor Senior Debt remaining unpaid, after giving
effect to any concurrent or distribution, or provision therefor, to or for the
holders of Guarantor Senior Debt.

     (b) To the extent any payment of Guarantor Senior Debt (whether by or on

whether in cash, property or securities, shall be received by any Holder when
such payment or distribution is prohibited by Section 11.11(a), such payment or
distribution shall be held in trust for the benefit of, and shall be paid over
or delivered to, the holders of Guarantor Senior Debt (pro rata to such holders
on the basis of the respective amount of Guarantor Senior Debt held by such
holders) or their respective Representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Guarantor Senior Debt may have
been issued, as their respective interests may appear, for application to the

Senior Debt has been paid in full in cash or Cash Equivalents, after giving
effect to any concurrent payment, distribution or provision therefor to or for
the holders of such Guarantor  Senior Debt.

     SECTION 11.12. Payments May Be Paid Prior to
                    Dissolution.
                    ------------------------------------

     Nothing contained in this Article Eleven or elsewhere in this Indenture
shall prevent (i) any Subsidiary Guarantor, except under the conditions set
forth in Sections 11.10 and 11.11, from making payments at any time for the
purpose of making payments of principal of and interest on the Notes, or from
depositing with the Trustee any moneys for such payments, or (ii) in the absence
of actual knowledge by the Trustee that a given payment would be prohibited by
Section 11.10 or 11.11, the application by the Trustee of any moneys deposited
with it for the purpose of making such payments of principal of and interest on
the Notes to the Holders entitled thereto unless at least one Business Day prior
to the date upon which such payment would otherwise become due and payable, the
Trustee shall have received the written notice provided for in Section 11.10(a)
or in Section 11.15 (provided that, notwithstanding the foregoing, such
application shall otherwise be subject to the provisions of the first sentence
of Section 11.10(a) and Section 11.11).  Each Subsidiary Guarantor shall give
prompt written notice to the Trustee of any dissolution, winding-up, liquidation
or reorganization of any Subsidiary Guarantor.

holders of Guarantor Senior Debt to receive payments or distributions of cash,
property or securities of such Subsidiary Guarantor
<PAGE>
 
                                      -88-

applicable to the Guarantor Senior Debt of such Subsidiary Guarantor until the
Notes shall be paid in full; and, for the purposes of such subrogation, no such
payments or distributions to the holders of the Guarantor Senior Debt by or on
behalf of such Subsidiary Guarantor or by or on behalf of the Holders by virtue
of this Article Eleven which otherwise would have been made to the Holders
shall, as between the Subsidiary Guarantors and the Holders of the Notes, be
deemed to be a payment by such Subsidiary Guarantor to or on account of the
Guarantor Senior Debt, it being understood that the provisions of this Article
Eleven are and are intended solely for the purpose of defining the relative
rights of the Holders of the Notes, on the one hand, and the holders of the
Guarantor Senior Debt, on the other hand.

     If any payment or distribution to which the Holders would otherwise have
been entitled but for the provisions of this Article Eleven shall have been
applied, pursuant to the provisions of this Article Eleven, to the payment of
amounts payable under the Guarantor Senior Debt, then the Holders shall be
entitled to receive from the holders of such Guarantor Senior Debt any payments
or distributions received by such holders of Guarantor Senior Debt in excess of
the amount sufficient to pay all amounts payable under or in respect of the
Guarantor Senior Debt in full in cash or Cash Equivalents.

     SECTION 11.14. Obligations of Each Guarantor
                    Unconditional.
                    ---------------------------------

     Nothing contained in this Article Eleven or elsewhere in this Indenture or
in the Notes or the Guarantees is intended to or shall impair, as among any
Subsidiary Guarantor, its creditors other than the holders of Guarantor Senior
Debt, and the Holders of the Notes, the obligation of such Subsidiary Guarantor,
which is absolute and unconditional, to pay to the Holders of the Notes the
principal of and any interest on the Notes as and when the same shall become due
and payable in accordance with the terms of the Guarantees, or is intended to or
shall affect the relative rights of the Holders of the Notes and creditors of
any Subsidiary Guarantor other than the holders of Guarantor Senior Debt, nor
shall anything herein or therein prevent the Holder of any Note or the Trustee
on its behalf from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, in respect of
cash, property or securities of any Subsidiary Guarantor received upon the
exercise of any such remedy.

     SECTION 11.15. Notice to Trustee.
                    ----------------- 

     The Company or any Subsidiary Guarantor shall give prompt written notice to
the Trustee of any fact known to the Company or any such Subsidiary Guarantor
which would prohibit the making of any payment to or by the Trustee in respect
of the Guarantees pursuant to the provisions of this Article Eleven.  Regardless
of anything to the contrary contained in this Article Eleven or elsewhere in
this Indenture, the Trustee  shall not be charged with knowledge of the
<PAGE>
 
                                      -89-


existence of any default or event of default with respect to any Guarantor
Senior Debt or of any other facts which would prohibit the making of any payment
to or by the Trustee unless and until the Trustee shall have received notice in
writing from the Company or a Subsidiary Guarantor, or from a holder of
Guarantor Senior Debt or a Representative therefor, and, prior to the receipt of
any such written notice, the Trustee shall be entitled to assume (in the absence
of actual knowledge to the contrary) that no such facts exist.

     In the event that the Trustee determines in good faith that any evidence is
required with respect to the right of any person as a holder of Guarantor Senior
Debt to participate in any payment or distribution pursuant to this Article
Eleven, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amounts of Guarantor Senior
Debt held by such person, the extent to which such person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such person under this Article Eleven, and if such evidence is not
furnished the Trustee may defer any payment to such person pending judicial
determination as to the right of such person to receive such payment.

     SECTION 11.16. Reliance on Judicial Order or
                    Certificate of Liquidating Agent.
                    -------------------------------- 

     Upon any payment or distribution of assets of any Subsidiary Guarantor
referred to in this Article Eleven, the Trustee, subject to the provisions of
Article Seven hereof, and the Holders of the Notes shall be entitled to rely
upon any order or decree made by any court of competent jurisdiction in which
bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings
are pending, or upon certificate of the receiver, trustee in bankruptcy,
liquidating trustee, agent or other person making such payment or distribution,
delivered to the Trustee or the holders of the Notes, for the purpose of
ascertaining the persons entitled to participate in such distribution, the
holders of the Guarantor Senior Debt and other Indebtedness of such Subsidiary
Guarantor, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article
Eleven.

     SECTION 11.17. Trustee's Relation to Guarantor Senior Debt.
                    ------------------------------------------- 

     The Trustee and any agent of any Subsidiary Guarantor or the Trustee shall
be entitled to all the rights set forth in this Article Eleven with respect to
any Guarantor Senior Debt which may at any time be held by it in its individual
or any other capacity to the same extent as any other holder of Guarantor Senior
Debt and nothing in this Indenture shall deprive the Trustee or any such agent
of any of its rights as such holder.

     With respect to the holders of Guarantor Senior Debt, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article Eleven, and no implied covenants
or obligations with respect to the holders of Guarantor Senior
<PAGE>
 
                                      -90-

Debt shall be read into this Indenture against the Trustee. The Trustee shall
not be deemed to owe any fiduciary duty to the holders of Guarantor Senior Debt
and shall not be liable to any such holders if the Trustee shall pay over or
distribute to or on behalf of Holders or any such Subsidiary Guarantor or any
other person money or assets to which any holders of Guarantor Senior Debt shall
be entitled by virtue of this Article, except if such payment is made as a
result of willful misconduct or gross negligence of the Trustee.

     Whenever a distribution is to be made or a notice given to holders or
owners of Guarantor Senior Debt, the distribution may be made and the notice
given to their Representatives, if any.

     SECTION 11.18. Subordination Rights Not Impaired by Acts or
                    Omissions of a Subsidiary Guarantor or Holders
                    of Guarantor Senior Debt.
                    ---------------------------------------------------

     No right of any present or future holders of any Guarantor Senior Debt to
enforce subordination as provided herein shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of any
Subsidiary Guarantor or by any act or failure to act, in good faith, by any such
holder, or by any noncompliance by such Subsidiary Guarantor with the terms of
this Indenture, regardless of any knowledge thereof which any such holder may
have or otherwise be charged with.

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Guarantor Senior Debt may, at any time and from time to time, without
the consent of or notice to the Trustee, without incurring responsibility to the
Trustee or the Holders of the Notes and without impairing or releasing the
subordination provided in this Article Eleven or the obligations hereunder of
the Holders of the Notes to the holders of the Guarantor Senior Debt, do any one
or more of the following:  (i) change the manner, place or terms of payment or
extend the time of payment of, or renew or alter, Guarantor Senior Debt, or
otherwise amend or supplement in any manner Guarantor Senior Debt, or any
instrument evidencing the same or any agreement under which Guarantor Senior
Debt is outstanding; (ii) sell, exchange, release or otherwise deal with any
property pledged, mortgaged or otherwise securing Guarantor Senior Debt; (iii)
release any person liable in any manner for the payment or collection of
Guarantor Senior Debt; and (iv) exercise or refrain from exercising any rights
against such Subsidiary Guarantor and any other person.

     SECTION 11.19. Noteholders Authorize Trustee To Effectuate
                    Subordination of Guarantees.
                    ----------------------------------------------

     Each Holder of Notes by its acceptance of them authorizes and expressly
directs the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate, as between the holders of Guarantor Senior Debt and
the Holders of Notes, the subordination
<PAGE>
 
                                      -91-

provided in this Article Eleven, and appoints the Trustee its attorney-in-fact
for such purposes, including, in the event of any dissolution, winding-up,
liquidation or reorganization of any Subsidiary Guarantor (whether in
bankruptcy, insolvency, receivership, reorganization or similar proceedings or
upon an assignment for the benefit of creditors or otherwise) tending towards
liquidation of the business as assets of such Subsidiary Guarantor, the filing
of a claim for the unpaid balance of its or his Notes and accrued interest in
the form required in those proceedings.

     If the Trustee does not file a proper claim or proof of debt in the form
required in such proceeding prior to 30 days before the expiration of the time
to file such claim or claims, then the holders of the Guarantor Senior Debt or
their Representative are or is hereby authorized to have the right to file and
are or is hereby authorized to file an appropriate claim for and on behalf of
the Holders of said Notes.  Nothing herein contained shall be deemed to
authorize the Trustee or the holders of Guarantor Senior Debt or their
Representative to authorize or consent to or accept or adopt on behalf of any
Holders any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee or the holders of Guarantor Senior Debt or their Representative to vote
in respect of the claim of any Holder in any such proceeding.

                    Events of Default.
                    ---------------------------------------

     The failure to make a payment on account of principal of or interest on the
Notes by reason of any provision of this Article Eleven will not be construed as
preventing the occurrence of an Event of Default.

                    ------------------------------------- 

     Nothing in this Article Eleven will apply to amounts due to the Trustee
pursuant to other sections in this Indenture.

                    ----------------------------------------

     1.  Interest.  KOPPERS INDUSTRIES, INC., a Pennsylvania corporation (the
         --------                                                            
"Company"), promises to pay interest on the principal amount of this Note at the
rate per annum shown above.  Interest on the Notes will accrue from the most
recent date on which interest has been paid or, if no interest has been paid,
from December 1, 1997.  The Company will pay interest semi-annually in arrears
on each Interest Payment Date, commencing June 1, 1998.  Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

     The Company shall pay interest on overdue principal and on overdue
installments of interest from time to time on demand at the rate borne by the
Notes and on overdue installments of interest (without regard to any applicable
grace periods) to the extent lawful.

     2.  Method of Payment.  The Company shall pay interest on the Notes (except
         -----------------                                                      
defaulted interest) to the Persons who are the registered Holders at the close
of business on the Record Date immediately preceding the Interest Payment Date
even if the Notes are canceled on registration of transfer or registration of
exchange after such Record Date.  Holders must surrender Notes to a Paying Agent
to collect principal payments.  The Company shall pay principal and interest in
money of the United States that at the time of payment is legal tender for
payment of public and private debts ("U.S. Legal Tender").  However, the Company
may pay principal and interest by its check payable in such U.S. Legal Tender.
The Company may deliver any such interest payment to the Paying Agent or to a
Holder at the Holder's registered address.

     3.   Paying Agent and Registrar.  Initially, PNC Bank, National Association
          --------------------------                                            
(the "Trustee") will act as Paying Agent and Registrar.  The Company may change
any Paying Agent, Registrar or co-Registrar without notice to the Holders.

     4.  Indenture.  The Company issued the Notes under an Indenture, dated as
         ---------                                                            
of December 1, 1997 (the "Indenture"), between the Company and the Trustee.
Capitalized terms herein are used as defined in the Indenture unless otherwise
defined herein.  This Note is one of a duly authorized issue of Initial Notes of
the Company designated as its 9 7/8% Senior Subordinated Notes due 2007 (the
"Initial Notes").  The Notes include the Initial Notes and the Exchange Notes
issued in exchange for the Initial Notes pursuant to the Registration Rights
Agreement.  The Initial Notes and the Exchange Notes are treated as a single
class of securities under the Indenture.  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 (15 U.S. Code (S)(S) 77aaa-77bbbb) (the "TIA"), as
in effect on the date of the Indenture.  Notwithstanding anything to the
contrary herein, the Notes are subject to all such terms, and Holders of Notes
are referred to the Indenture and said Act for a statement of them.  The Notes
are general unsecured obligations of the Company limited in aggregate principal
amount to $175,000,000.  Under certain circumstances as provided for in Article
Eleven of the Indenture, the payment on each Note may be guaranteed on a senior
subordinated basis by the Subsidiary Guarantors.  Each Holder, by

                                     A.1-3
<PAGE>
 
accepting a Note, agrees to be bound by all of the terms and provisions of the
Indenture, as the same may be amended from time to time.

     5.   Subordination.  The Notes are subordinated in right of payment, in the
          -------------                                                         
manner and to the extent set forth in the Indenture, to the prior payment in
full in cash or Cash Equivalents of all Senior Debt of the Company, whether
outstanding on the date of the Indenture or thereafter created, incurred,
assumed or guaranteed.  The Guarantees in respect of the Notes will be
subordinated in right of payment, in the manner and to the extent set forth in
the Indenture, to the prior payment in full in cash or Cash Equivalents of all
Guarantor Senior Debt of each Subsidiary Guarantor, whether outstanding on the
date of the Indenture or thereafter created, incurred, assumed or guaranteed.
Each Holder by its acceptance hereof agrees to be bound by such provisions and
authorizes and expressly directs the Trustee, on its behalf, to take such action
as may be necessary or appropriate to effectuate the subordination provided for
in the Indenture and appoints the Trustee its attorney-in-fact for such
purposes.

     6.  Redemption Provisions.  Except as provided below, the Notes may not be
         ---------------------

     (a)  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 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:


          Year                   Redemption Price
          ----                   ----------------

          2002                       104.938%
          2003                       103.292%
          2004                       101.646%

plus accrued and unpaid interest, if any, to the date of such redemption.

          (b)  Notwithstanding the foregoing, 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 and that any such redemption occurs within 90 days following the
closing of any such offering.

                                     A.1-4
<PAGE>
 
          7.  Notice of Redemption.  Notice of redemption will be mailed at
              --------------------                                         
least 30 days but not more than 60 days before the Redemption Date.  Notes in
denominations larger than $1,000 may be redeemed in part.

          Except as set forth in the Indenture, if monies for the redemption of
the Notes called for redemption shall have been deposited with the Paying Agent
for redemption on such Redemption Date, then, unless the Company defaults in the
payment of such Redemption Price plus accrued interest, if any, the Notes called
for redemption will cease to bear interest from and after such Redemption Date
and the only right of the Holders of such Notes will be to receive payment of
the Redemption Price plus accrued interest, if any.

          8.  Offers to Purchase.  Section 4.15 of the Indenture provides that,
              ------------------                                               
upon a Change of Control, each holder will have the right, subject to certain
conditions set forth in the Indenture, to require the Company to repurchase such
holder's Notes at a price equal to 101% of the principal amount thereof plus
accrued interest to the date of repurchase.  Section 4.16 of the Indenture
provides that, after certain Asset Dispositions, and subject to further
limitations contained therein, the Company will make an offer to purchase
certain amounts of the Notes in accordance with the procedures set forth in the
Indenture.

          9.  Denominations; Transfer; Exchange.  The Notes are in registered
              ---------------------------------                              
form, without coupons, in denominations of $1,000 and integral multiples of
$1,000.  A Holder shall register the transfer of or exchange Notes in accordance
with the Indenture.  The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay certain
transfer taxes or similar governmental charges payable in connection therewith
as permitted by the Indenture.  The Registrar need not register the transfer of
or exchange of any Notes or portions thereof selected for redemption.

          10.  Persons Deemed Owners.  The registered Holder of a Note shall be
               ---------------------                                           
treated as the owner of it for all purposes.

          11.  Unclaimed Money.  If money for the payment of principal or
               ---------------                                           
interest remains unclaimed for three years, the Trustee and the Paying Agent
will pay the money back to the Company.  After that, all liability of the
Trustee and such Paying Agent with respect to such money shall cease.

          12.  Discharge Prior to Redemption or Maturity.  If the Company at any
               -----------------------------------------                        
time deposits with the Trustee U.S. Legal Tender or U.S. Government Obligations
sufficient to pay the principal of and interest on the Notes to redemption or
maturity and complies with the other provisions of the Indenture relating
thereto, the Company will be discharged from certain provisions of the Indenture
and the Notes (including certain covenants, but excluding its obligation to pay
the principal of and interest on the Notes).

          13.  Amendment; Supplement; Waiver.  Subject to certain exceptions,
               -----------------------------                                 
the Indenture, the Notes or the Guarantee, if any, may be amended or
supplemented with the written consent of the

                                     A.1-5
<PAGE>
 
Holders of at least a majority in aggregate principal amount of the Notes then
outstanding, and any existing Default or Event of Default or noncompliance with
any provision may be waived with the written consent of the Holders of a
majority in aggregate principal amount of the Notes then outstanding.  Without
notice to or consent of any Holder, the parties thereto may amend or supplement
the Indenture or the Notes to, among other things, cure any ambiguity, defect or
inconsistency, provide for uncertificated Notes in addition to or in place of
certificated Notes, or comply with Article Five of the Indenture or make any
other change that does not adversely affect in any material respect the rights
of any Holder of a Note.

          14.  Restrictive Covenants.  The Indenture imposes certain limitations
               ---------------------                                            
on the ability of the Company and its Subsidiaries to, among other things, incur
additional Debt or Liens, make payments in respect of its Capital Stock or
subordinated obligations, enter into transactions with Affiliates, create
dividend or other payment restrictions affecting Subsidiaries, incur Debt that
is, by its terms, subordinated or junior to any other Debt and senior to the
Notes, merge or consolidate with any other Person, sell, assign, transfer,
lease, convey or otherwise dispose of all or substantially all of its assets or
adopt a plan of liquidation and sell Capital Stock of a Subsidiary.  Such
limitations are subject to a number of important qualifications and exceptions.
The Company must annually and quarterly report to the Trustee on compliance with
such limitations.

          15.  Successors.  When a successor assumes, in accordance with the
               ----------                                                   
Indenture, all the obligations of its predecessor under the Notes and the
Indenture, the predecessor will be released from those obligations.

          16.  Defaults and Remedies.  If an Event of Default occurs and is
               ---------------------                                       
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of Notes then outstanding may declare all the Notes to be due and payable
in the manner, at the time and with the effect provided in the Indenture.
Holders of Notes may not enforce the Indenture or the Notes except as provided
in the Indenture.  The Trustee is  not obligated to enforce the Indenture or the
Notes unless it has received indemnity reasonably satisfactory to it.  The
Indenture permits, subject to certain limitations therein provided, Holders of a
majority in aggregate principal amount of the Notes then outstanding to direct
the Trustee in its exercise of any trust or power.  The Trustee may withhold
from Holders of Notes notice of any continuing Default or Event of Default
(except a Default in payment of principal or interest) if it determines that
withholding notice is in their interest.

               -----------------------------                                   
in its individual or any other capacity, may become the owner or pledgee of
Notes and may otherwise deal with the Company, its Subsidiaries or their
respective Affiliates as if it were not the Trustee.

          18.  No Recourse Against Others.  No stockholder, director, officer,
               --------------------------                                     
employee or incorporator, as such, of the Company shall have any liability for
any obligation of the Company under the Notes or the Indenture.  Each Holder of
a Note by accepting a Note waives and

                                     A.1-6

releases all such liability.  The waiver and release are part of the
consideration for the issuance of the Notes.

          19.  Authentication.  This Note shall not be valid until the Trustee

Note.

          20.  Governing Law.  The laws of the State of New York shall govern

this Note and the Indenture, without regard to principles of conflict of laws.

          21.  Abbreviations and Defined Terms.  Customary abbreviations may be

               -------------                                                  
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes as a convenience to the Holders of the

          23.  Indenture.  Each Holder, by accepting a Note, agrees to be bound
               ---------

                    9 7/8% Senior Subordinated Note due 2007

     1.  Interest.  KOPPERS INDUSTRIES, INC., a Pennsylvania corporation (the
         --------                                                            
"Company"), promises to pay interest on the principal amount of this Note at the
rate per annum shown above.  Interest on the Notes will accrue from the most
recent date on which interest has been paid or, if no interest has been paid,
from December 1, 1997.  The Company will pay interest semi-annually in arrears
on each Interest Payment Date, commencing June 1, 1998.  Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

     The Company shall pay interest on overdue principal and on overdue
installments of interest from time to time on demand at the rate borne by the
Notes and on overdue installments of interest (without regard to any applicable
grace periods) to the extent lawful.

     2.  Method of Payment.  The Company shall pay interest on the Notes (except
         -----------------                                                      
defaulted interest) to the Persons who are the registered Holders at the close
of business on the Record Date immediately preceding the Interest Payment Date
even if the Notes are canceled on registration of transfer or registration of
exchange after such Record Date.  Holders must surrender Notes to a Paying Agent
to collect principal payments.  The Company shall pay principal and interest in
money of the United States that at the time of payment is legal tender for
payment of public and private debts ("U.S. Legal Tender").  However, the Company
may pay principal and interest by its check payable in such U.S. Legal Tender.
The Company may deliver any such interest payment to the Paying Agent or to a
Holder at the Holder's registered address.

     3.   Paying Agent and Registrar.  Initially, PNC Bank, National Association
          --------------------------                                            
(the "Trustee") will act as Paying Agent and Registrar.  The Company may change
any Paying Agent, Registrar or co-Registrar without notice to the Holders.

     4.   Indenture.  The Company issued the Notes under an Indenture, dated as
          ---------                                                            
of December 1, 1997 (the "Indenture"), between the Company and the Trustee.
Capitalized terms herein are used as defined in the Indenture unless otherwise
defined herein.  This Note is one of a duly authorized issue of Exchange Notes
of the Company designated as its 9 7/8% Senior Subordinated Notes due 2007 (the
"Exchange Notes").  The Notes include the Initial Notes and the Exchange Notes
issued in exchange for the Initial Notes pursuant to the Registration Rights
Agreement.  The Initial Notes and the Exchange Notes are treated as a single
class of securities under the Indenture.  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 (15 U.S. Code (S)(S) 77aaa-77bbbb) (the "TIA"), as
in effect on the date of the Indenture.  Notwithstanding anything to the
contrary herein, the Notes are subject to all such terms, and Holders of Notes
are referred to the Indenture and said Act for a statement of them.  The Notes
are general unsecured obligations of the Company limited in aggregate principal
amount to $175,000,000.  Under certain circumstances as provided for in Article
Eleven of the Indenture, the payment on each Note may be guaranteed on a senior
subordinated basis by the Subsidiary Guarantors.  Each Holder, by


                                     A.2-2
<PAGE>
 
accepting a Note, agrees to be bound by all of the terms and provisions of the
Indenture, as the same may be amended from time to time.

     5.   Subordination.  The Notes are subordinated in right of payment, in the
          -------------                                                         
manner and to the extent set forth in the Indenture, to the prior payment in
full in cash or Cash Equivalents of all Senior Debt of the Company, whether
outstanding on the date of the Indenture or thereafter created, incurred,
assumed or guaranteed.  The Guarantees in respect of the Notes will be
subordinated in right of payment, in the manner and to the extent set forth in
the Indenture, to the prior payment in full in cash or Cash Equivalents of all
Guarantor Senior Debt of each Subsidiary Guarantor, whether outstanding on the
date of the Indenture or thereafter created, incurred, assumed or guaranteed.
Each Holder by its acceptance hereof agrees to be bound by such provisions and
authorizes and expressly directs the Trustee, on its behalf, to take such action
as may be necessary or appropriate to effectuate the subordination provided for
in the Indenture and appoints the Trustee its attorney-in-fact for such
purposes.

     6.  Redemption Provisions.  Except as provided below, the Notes may not be

denominations larger than $1,000 may be redeemed in part.

     Except as set forth in the Indenture, if monies for the redemption of the
Notes called for redemption shall have been deposited with the Paying Agent for
redemption on such Redemption Date, then, unless the Company defaults in the
payment of such Redemption Price plus accrued interest, if any, the Notes called
for redemption will cease to bear interest from and after such Redemption Date
and the only right of the Holders of such Notes will be to receive payment of
the Redemption Price plus accrued interest, if any.

     8.  Offers to Purchase.  Section 4.15 of the Indenture provides that, upon
         ------------------

conditions set forth in the Indenture, to require the Company to repurchase such
holder's Notes at a price equal to 101% of the principal amount thereof plus
accrued interest to the date of repurchase.  Section 4.16 of the Indenture

limitations contained therein, the Company will make an offer to purchase
certain amounts of the Notes in accordance with the procedures set forth in the
Indenture.

         ---------------------------------                                    
without coupons, in denominations of $1,000 and integral multiples of $1,000.  A
Holder shall register the transfer of or exchange Notes in accordance with the
Indenture.  The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay certain transfer
taxes or similar governmental charges payable in connection therewith as
permitted by the Indenture.  The Registrar need not register the transfer of or
exchange of any Notes or portions thereof selected for redemption.

     10.  Persons Deemed Owners.  The registered Holder of a Note shall be
          ---------------------                                           
treated as the owner of it for all purposes.

     11.  Unclaimed Money.  If money for the payment of principal or interest
          ---------------

money back to the Company.  After that, all liability of the Trustee and such
Paying Agent with respect to such money shall cease.

and the Notes (including certain covenants, but excluding its obligation to pay

     13.  Amendment; Supplement; Waiver.  Subject to certain exceptions, the
          -----------------------------                                     
Indenture, the Notes or the Guarantee, if any, may be amended or supplemented
with the written consent of the

                                     A.2-4
<PAGE>
 
Holders of at least a majority in aggregate principal amount of the Notes then
outstanding, and any existing Default or Event of Default or noncompliance with
any provision may be waived with the written consent of the Holders of a
majority in aggregate principal amount of the Notes then outstanding.  Without
notice to or consent of any Holder, the parties thereto may amend or supplement
the Indenture or the Notes to, among other things, cure any ambiguity, defect or
inconsistency, provide for uncertificated Notes in addition to or in place of
certificated Notes, or comply with Article Five of the Indenture or make any
other change that does not adversely affect in any material respect the rights
of any Holder of a Note.

          ---------------------

additional Debt or Liens, make payments in respect of its Capital Stock or
subordinated obligations, enter into transactions with Affiliates, create
dividend or other payment restrictions affecting Subsidiaries, incur additional
Debt that is by its terms subordinated or junior to any other Debt and senior to
the Notes, merge or consolidate with any other Person, sell, assign, transfer,
lease, convey or otherwise dispose of all or substantially all of its assets or

limitations are subject to a number of important qualifications and exceptions.

Indenture, the predecessor will be released from those obligations.

amount of Notes then outstanding may declare all the Notes to be due and payable

majority in aggregate principal amount of the Notes then outstanding to direct
the Trustee in its exercise of any trust or power.  The Trustee may withhold
from Holders of Notes notice of any continuing Default or Event of Default
(except a Default in payment of principal or interest) if it determines that
withholding notice is in their interest.

     17.  Trustee Dealings with Company.  The Trustee under the Indenture, in
          -----------------------------                                      
its individual or any other capacity, may become the owner or pledgee of Notes
and may otherwise deal with the Company, its Subsidiaries or their respective
Affiliates as if it were not the Trustee.

     18.  No Recourse Against Others.  No stockholder, director, officer,
          --------------------------                                     
employee or incorporator, as such, of the Company shall have any liability for
any obligation of the Company under the Notes or the Indenture.  Each Holder of
a Note by accepting a Note waives and


                                     A.2-5
<PAGE>
 
releases all such liability.  The waiver and release are part of the
consideration for the issuance of the Notes.

     19.  Authentication.  This Note shall not be valid until the Trustee or
          --------------

               9 7/8% Senior Subordinated
               Notes due 2007
               ----------------------------

Ladies and Gentlemen:

     We are delivering this letter in connection with a proposed purchase of 9
7/8% Senior Subordinated Notes due 2007 (the "Notes") of Koppers Industries,
Inc. (the "Company").

     We hereby confirm that:

          (i) we are an "accredited investor" within the meaning of Rule
     501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended
     (the "Securities Act"), or an entity in which all of the equity owners are
     accredited investors within the meaning of Rule 501(a)(1), (2), (3) or (7)
     under the Securities Act (an "Institutional Accredited Investor");

          (ii) any purchase of Notes by us will be for our own account or for
     the account of one or more other Institutional Accredited Investors;

          (iii)  in the event that we purchase any Notes, we will acquire Notes
     having a minimum purchase price of at least $100,000 for our own account
     and for each separate account for which we are acting;

          (iv) we have such knowledge and experience in financial and business
     matters that we are capable of evaluating the merits and risks of
     purchasing Notes;

          (v) we are not acquiring Notes with a view to any distribution thereof
     in a transaction that would violate the Securities Act or the securities
     laws of any State of the United States or any other applicable
     jurisdiction; provided that the disposition of our

                                      C-1
<PAGE>
 
     property and the property of any accounts for which we are acting as
     fiduciary shall remain at all times within our control; and

          (vi) we acknowledge that we have had access to such financial and
     other information, and have been afforded the opportunity to ask such
     questions of representatives of the Company and receive answers thereto, as
     we deem necessary in connection with our decision to purchase Notes.

     We understand that the Notes are being offered in a transaction not
involving any public offering within the meaning of the Securities Act and that
the Notes have not been registered under the Securities Act, and we agree, on
our own behalf and on behalf of each account for which we acquire any Notes,
that such Notes may be offered, resold, pledged or otherwise transferred only
(i) to a person whom we reasonably believe to be a qualified institutional buyer
(as defined in Rule 144A under the Securities Act), in a transaction meeting the
requirements of Rule 144A, in a transaction meeting the requirements of Rule
144, outside the United states in a transaction meeting the requirements of Rule
904 under the Securities Act, or in accordance with another exemption from the
registration requirements of the Securities Act (and based upon an opinion of
counsel if the Company so requests), (ii) to the Company or (iii) pursuant to an
effective registration statement, and, in each case, in accordance with any
applicable securities laws of any State of the United States or any other
applicable jurisdiction.  We understand that the registrar will not be required
to accept for registration of transfer any Notes, except upon presentation of
evidence satisfactory to the Company that the foregoing restrictions on transfer
have been complied with.  We further understand that the Notes purchased by us
will be in the form of definitive physical certificates and that such
certificates will bear a legend reflecting the substance of this paragraph.

     We acknowledge that you and others will rely upon our confirmation,
acknowledgments and agreements set forth herein, and we agree to notify you
promptly in writing if any of our representations or warranties herein ceases to
be accurate and complete.

or Commission policy, the Company and the Subsidiary Guarantors shall (i) cause
to be
<PAGE>
 
                                      -5-

filed with the Commission as soon as practicable on or prior to 45 days after
the Closing Date, a Registration Statement under the Act relating to the New

the Act, (C) cause all necessary filings in connection with the registration and
qualification of the New Notes to be made under the Blue Sky laws of such
jurisdictions as are necessary to permit Consummation of the Exchange Offer
(provided, however, that the Company and the Subsidiary Guarantors shall not be
obligated to qualify as foreign corporations in any jurisdiction in which they
are not so qualified or to take any action that would subject them to general
service of process or taxation in any jurisdiction where they are not so
subject, except service of process with respect to the offering and sale of the
Notes and Exchange Notes) and (D) upon the effectiveness of such Registration
Statement, commence the Exchange Offer and use their best efforts to issue on or
prior to 45 days after the Exchange Offer Effective Date, New Notes in exchange

on the appropriate form permitting registration of the New Notes to be offered
in exchange for the Transfer Restricted Securities and to permit resales of New
Notes held by Broker-Dealers as contemplated by Section 3(c) below.  If, after
such Exchange Offer Registration Statement initially is declared effective by
the Commission, the Exchange Offer or the issuance of New Notes under the
Exchange Offer or the resale of New Notes received by Broker-Dealers in the
Exchange Offer as contemplated by Section 3(c) below is inter fered with by any
stop order, injunction or other order or requirement of the Commission or any
other governmental agency or court, such Registration Statement shall be deemed
not to have become effective for purposes of this Agreement during the period
that such stop order, injunction or other similar order or requirement shall
remain in effect.

          (b) The Company shall cause the Exchange Offer Registration Statement
to be effective continuously and shall keep the Exchange Offer open for a period
of not less than the minimum period required under applicable federal and state
securities laws to Consummate the Exchange Offer; provided, however, that in no
                                                  --------  -------            
event shall such period be less than 20

                                      -6-

business days.  The Company and the Subsidiary Guarantors shall cause the
Exchange Offer to comply with all applicable federal and state securities laws.
The Company and the Subsidiary Guarantors shall only offer to exchange New Notes
for Old Notes in the Exchange Offer, and only the New Notes shall be registered
under the Exchange Offer Registration Statement.

          (c) The Company shall indicate in a "Plan of Distribution" section
contained in the Prospectus included in the Exchange Offer Registration
Statement that any Broker-Dealer that holds Old Notes that are Transfer
Restricted Securities and that were acquired for its own account as a result of
market-making activities or other trading activities (other than Transfer
Restricted Securities acquired directly from the Company), may exchange such Old
Notes pursuant to the Exchange Offer; provided, however, that such Broker-Dealer
                                      --------  -------                         
may be deemed to be an "underwriter" within the meaning of the Act and must,
therefore, deliver a prospectus meeting the requirements of the Act in
connection with any resales of the New Notes received by such Broker-Dealer in
the Exchange Offer.  Such "Plan of Distribution" section shall allow the use of
the Prospectus by all Persons subject to the prospectus delivery requirements of
the Act, including Participating Broker-Dealers, and shall also contain all
other information with respect to such resales by Broker-Dealers that the
Commission may require to permit such resales pursuant thereto, but such "Plan
of Distribution" shall not name any such Broker-Dealer or disclose the amount of
Notes held by any such Broker-Dealer except to the extent required by the
Commission as a result of a change in policy after the date of this Agreement.

          The Company and the Subsidiary Guarantors shall use their best efforts
to keep the Exchange Offer Registration Statement continuously effective,
supplemented and amended as required by the provisions of Section 6(c) below to
the extent necessary to ensure that it is available for resales of Notes
acquired by Broker-Dealers for their own accounts as a result of market-making
activities or other trading activities, and to ensure that it conforms with the
requirements of this Agreement, the Act and the policies, rules and regulations
of the Commission as announced from time to time.  The Company shall provide
sufficient copies of the latest version of such Prospectus to Broker-Dealers
promptly upon request at any time during such period in order to facilitate such

of liquidated damages of $.30 per week per $1,000 in principal amount of Notes
constituting Transfer Restricted Securities.  Notwithstanding the foregoing, the
Company and the Subsidiary Guarantors shall not be required to pay liquidated
damages to each Holder of Transfer Restricted Securities if the Registration
Default arises from the failure of the Company and the Subsidiary Guarantors to
file, or cause to become effective, a Shelf Registration Statement within the
time period required by Section 4 of this Agreement and such Registration
Default is by reason of the failure of the Holders to provide the information
regarding the Holder reasonably requested by the Company, the NASD or any other
regulatory agency having jurisdiction over any of the Holders at least 10
business days prior to such Registration Default.  All accrued liquidated
damages shall be paid by the Company and the Subsidiary Guarantors on each
Damages Payment Date to the Holders 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 relating to any particular Transfer Restricted
Securities, the accrual of liquidated damages with respect to such Transfer
Restricted Securities will cease.

          All obligations of the Company and the Subsidiary Guarantors set forth
in the preceding paragraph that are outstanding with respect to any Transfer
Restricted Security at the time such security ceases to be a Transfer Restricted
Security shall survive until such time as all such obligations with respect to
such Transfer Restricted Security shall have been satisfied in full.

          SECTION 6.  REGISTRATION PROCEDURES

          (a) Exchange Offer Registration Statement.  In connection with the
              -------------------------------------                         
Exchange Offer, the Company and the Subsidiary Guarantors shall comply with all
of the provisions of Section 6(c) below, shall use their best efforts to effect
such exchange to permit the sale of Transfer Restricted Securities being sold in
accordance with the intended method or methods of distribution thereof, and
shall comply with all of the following provisions:

             (i) If, due to a change in law or Commission policy after the date
     hereof, in the reasonable opinion of special counsel to the Company there
     is a question as to whether the Exchange Offer is permitted by applicable
     federal law or Commission policy, the Company hereby agrees to seek a no-
<PAGE>
 
                                      -10-

     action letter or other favorable decision from the Commission allowing the
     Company and the Subsidiary Guarantors to Consummate an Exchange Offer for
     such Old Notes.  The Company hereby agrees to pursue the issuance of such a
     no-action letter or favorable decision to the Commission staff level but
     shall not be required to take commercially unreasonable action to effect a
     change of Commission policy.  The Company hereby agrees, however, to (A)
     participate in telephonic conferences with the Commission, (B) deliver to
     the Commission an analysis prepared by special counsel to the Company
     setting forth the legal bases, if any, upon which such counsel has
     concluded that such an Exchange Offer should be permitted and (C)
     diligently pursue a resolution (which need not be favorable) by the
     Commission of such submission.  The Initial Purchaser shall be given prior
     notice of any action taken by the Company under this clause (i).

             (ii) As a condition to its participation in the Exchange Offer
     pursuant to the terms of this Agreement, each Holder of Transfer Restricted
     Securities shall furnish, upon the request of the Company, prior to the
     Consummation of the Exchange Offer, a written representation to the Company
     (which may be contained in the letter of transmittal contemplated by the
     Exchange Offer Registration Statement) to the effect that (A) it is not an
     affiliate of the Company or any of the Subsidiary Guarantors, (B) it is not
     engaged in, and does not intend to engage in, and has no arrangement or
     understanding with any person to participate in, a distribution of the New
     Notes to be issued in the Exchange Offer and (C) it is acquiring the New
     Notes in its ordinary course of business.  In addition, all such Holders of
     Transfer Restricted Securities shall otherwise cooperate in the Company's
     preparations for the Exchange Offer.

             (iii)  The Company, the Subsidiary Guarantors and the Initial
     Purchaser acknowledge that the staff of the Commission has taken the
     position that any broker-dealer that owns New Notes that were received by
     such broker-dealer for its own account in the Exchange Offer (a
                                                                    
     "Participating Broker-Dealer") may be deemed to be an "underwriter" within
     ----------------------------                                              
     the meaning of the Act and must deliver a prospectus meeting the
     requirements of the Act in connection with any resale of such New Notes
     (other than a resale of an unsold allotment resulting from the original
     offering of the Notes).

          The Company, the Subsidiary Guarantors and the Initial Purchaser also
     acknowledge that it is the Commission staff's
<PAGE>
 
                                      -11-

     position that if the Prospectus contained in the Exchange Offer
     Registration Statement includes a plan of distribution containing a
     statement to the above effect and the means by which Participating Broker-
     Dealers may resell the New Notes, without naming the Participating Broker-
     Dealers or specifying the amount of New Notes owned by them, such
     Prospectus may be delivered by Participating Broker-Dealers to satisfy
     their prospectus delivery obligations under the Act in connection with
     resales of New Notes for their own accounts, so long as the Prospectus
     otherwise meets the requirements of the Act.

          (b) Shelf Registration Statement.  In the event that a Shelf
              ----------------------------                            
Registration Statement is required by this Agreement, the Company and the
Subsidiary Guarantors shall comply with all the provisions of Section 6(c) of
this Agreement and shall use their best efforts to effect such registration to
permit the sale of the Transfer Restricted Securities being sold in accordance
with the intended method or methods of distribution of such Transfer Restricted
Securities and, in connection therewith, the Company and the Subsidiary
Guarantors will as expeditiously as possible prepare and file with the
Commission a Shelf Registration Statement relating to the registration on any
appropriate form under the Act, which form shall be available for the sale of
the Transfer Restricted Securities in accordance with the intended method or
methods of distribution of such Transfer Restricted Securities.

          (c) General Provisions.  In connection with any Registration Statement
              ------------------                                                
and any Prospectus required by this Agreement to permit the sale or resale of
Transfer Restricted Securities (including, without limitation, any Registration
Statement and the related Prospectus, to the extent that the same are required
to be available to permit resales of Notes by Broker-Dealers), the Company and
the Subsidiary Guarantors shall:

             (i) use their best efforts to keep such Registration Statement
     continuously effective for the applicable time period required hereunder
     and provide all requisite financial statements (including, if required by
     the Act or any regulation thereunder, financial statements of the
     Subsidiary Guarantors) for the period specified in Section 3 or 4 of this
     Agreement, as applicable; upon the occurrence of any event that would cause
     any such Registration Statement or the Prospectus contained therein (A) to
     contain a material misstatement or omission or (B) not to be effective and
     usable for resale of Transfer Restricted Securities during the period
     required by this Agreement, the
<PAGE>
 
                                      -12-

     Company shall promptly notify the Holders to suspend use of the Prospectus,
     and the Holders shall suspend use of the Prospectus, and such Holders shall
     not communicate non-public information to any third party, in violation of
     the securities laws, until the Company and the Subsidiary Guarantors have
     made an appropriate amendment to such Registration Statement, in the case
     of clause (A), correcting any such misstatement or omission, and, in the
     case of either clause (A) or (B), the Company and the Subsidiary Guarantors
     shall use their best efforts to cause such amendment to be declared
     effective and such Registration Statement and the related Prospectus to
     become usable for their intended purpose(s) as soon as practicable
     thereafter;

             (ii) prepare and file with the Commission such amendments and post-
     effective amendments to such Registration Statement as may be necessary to
     keep the Registration Statement effective for the applicable period set
     forth in Section 3 or 4 of this Agreement, as applicable, or such shorter
     period as will terminate when all Transfer Restricted Securities covered by
     such Registration Statement have been sold; cause the Prospectus to be
     supplemented by any required Prospectus supplement, and as so supplemented
     to be filed pursuant to Rule 424 under the Act during the applicable time
     period required hereunder and to comply fully with the applicable
     provisions of Rules 424 and 430A under the Act in a timely manner; and
     comply with the provisions of the Act and the Exchange Act with respect to
     the disposition of all Transfer Restricted Securities covered by such
     Registration Statement during such period in accordance with the intended
     method or methods of distribution by the sellers of such securities set
     forth in such Registration Statement as so amended or in such Prospectus as
     so supplemented;

             (iii)  advise the underwriter(s), if any, the Initial Purchaser,
     and, in the case of a Shelf Registration Statement, each of the selling
     Holders promptly and, if requested by such Persons, to confirm such advice
     in writing, (A) when the Prospectus or any prospectus supplement or post-
     effective amendment has been filed and, with respect to any Registration
     Statement or any post-effective amendment thereto, when the same has become
     effective, (B) of any request by the Commission for amendments to the
     Registration Statement or amendments or supplements to the Prospectus or
     for additional information relating to such Registration Statement or
     Prospectus,
<PAGE>
 
                                      -13-

     (C) of the issuance by the Commission of any stop order suspending the
     effectiveness of the Registration Statement under the Act or of the
     suspension by any state securities commission of the qualification of the
     Transfer Restricted Securities for offering or sale in any jurisdiction, or
     the initiation of any proceeding for any of the preceding purposes, (D) of
     the existence of any fact or the happening of any event that makes any
     statement of a material fact made in the Registration Statement, the
     Prospectus, any amendment or supplement to such Registration Statement or
     Prospectus, as the case may be, or any document incorporated by reference
     in such Registration Statement or Prospectus untrue in any material
     respect, or that requires the making of any additions to or changes in the
     Registration Statement or the Prospectus in order to make the statements in
     such Registration Statement or Prospectus not misleading and that in the
     case of the Prospectus, it will not contain any untrue statement of a
     material fact or omit to state any material fact required to be stated
     therein or necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading.  If at any time
     the Commission shall issue any stop order suspending the effectiveness of
     the Registration Statement, or any state securities commission or other
     regulatory authority shall issue an order suspending the qualification or
     exemption from qualification of the Transfer Restricted Securities under
     state securities or Blue Sky laws, the Company and the Subsidiary
     Guarantors shall use their best efforts to obtain the withdrawal or lifting
     of such order at the earliest possible time;

             (iv) furnish to each of the underwriter(s), if any, the Initial
     Purchaser and, in the case of a Shelf Registration Statement, each of the
     selling Holders before filing with the Commission, copies of any
     Registration Statement or any Prospectus included in such Registration
     Statement or Prospectus or any amendments or supplements to any such
     Registration Statement or Prospectus (including all documents incorporated
     by reference after the initial filing of such Registration Statement),
     which documents will be subject to the reasonable review of such
     underwriter(s), if any, the Initial Purchaser, and such Holders for a
     period of at least five business days, and the Company and the Subsidiary
     Guarantors will not file any such Registration Statement or Prospectus or
     any amendment or supplement to any such Registration Statement or
     Prospectus, as the case may be, (including all such documents incorporated
     by reference) to which any underwriter, Initial Purchaser or
<PAGE>
 
                                      -14-

     selling Holder shall reasonably object within five business days after the
     receipt of such Registration Statement or Prospectus.  A selling Holder or
     underwriter, if any, shall be deemed to have reasonably objected to such
     filing if such Registration Statement, Prospectus, amendment or supplement,
     as applicable, as proposed to be filed, contains a material misstatement or
     omission;

             (v) promptly prior to the filing of any document that is to be
     incorporated by reference into a Registration Statement or Prospectus, (a)
     provide copies of such document to the selling Holders and to the
     underwriter(s), if any, (b) make the Company's and the Subsidiary
     Guarantors' representatives available for discussion of such document and
     other customary due diligence matters; provided that such discussion and
                                            --------                         
     due diligence shall be coordinated on behalf of the selling Holders by one
     counsel designated by and on behalf of such selling Holders and (c) include
     such information in such document prior to the filing of such document as
     such selling Holders or underwriter(s), if any, may reasonably request;

             (vi) make available at reasonable times for inspection by the
     selling Holders, any underwriter participating in any disposition pursuant
     to such Registration Statement and any attorney or accountant retained by
     such selling Holders or any of the underwriter(s), if any, at the offices
     where normally kept, during reasonable business hours, all relevant
     financial and other records, pertinent corporate documents and properties
     of the Company and the Subsidiary Guarantors and cause the Company's and
     the Subsidiary Guarantors' officers, directors and employees to supply all
     information reasonably requested by any such Holder, underwriter, attorney
     or accountant in connection with such Registration Statement subsequent to
     the filing thereof and prior to its effectiveness; provided, however, that
                                                        --------  -------      
     such persons shall first agree in writing with the Company that any
     information that is reasonably and in good faith designated by the Company
     in writing as confidential at the time of delivery of such information
     shall be kept confidential by such persons, unless and to the extent that
     (i) disclosure of such information is required by court or administrative
     order or is necessary to respond to inquiries of regulatory authorities,
     (ii) disclosure of such information is required by law (including any
     disclosure requirements pursuant to federal securities laws in connection
     with the filing of the Shelf Registration Statement or the use of any
     Prospectus), (iii) such
<PAGE>
 
                                      -15-

     information becomes generally available to the public other than as a
     result of a disclosure or failure to safeguard such information by such
     person or (iv) such information becomes available to such person from a
     source other than the Company and its Subsidiaries and such source is not
     bound by a confidentiality agreement;

             (vii)  if requested by any selling Holders or the underwriter(s),
     if any, promptly incorporate in any Registration Statement or Prospectus,
     pursuant to a supplement or post-effective amendment if necessary, such
     information as such selling Holders and underwriter(s), if any, may
     reasonably request to have included therein, including, without limitation,
     information relating to the "Plan of Distribution" of the Transfer
     Restricted Securities, information with respect to the principal amount of
     Transfer Restricted Securities being sold to such underwriter(s), the
     purchase price being paid for Transfer Restricted Securities and any other
     terms of the offering of the Transfer Restricted Securities to be sold in
     such offering; and make all required filings of such Prospectus supplement
     or post-effective amendment as soon as practicable after the Company is
     notified of the matters to be incorporated in such Prospectus supplement or
     post-effective amendment; provided, however, that the Company shall not be
                               --------  -------                               
     required to take any action pursuant to this Section 6(c)(vii) that would,
     in the opinion of counsel for the Company, violate applicable law;

             (viii)  furnish to each underwriter, if any, the Initial Purchaser
     and upon request to the Company to a selling Holder without charge, at
     least one conformed copy of the Registration Statement, as first filed with
     the Commission, and of each amendment thereto, including, upon the request
     of such Person, all documents incorporated by reference therein and all
     exhibits to the extent requested (including exhibits incorporated therein
     by reference);

             (ix) deliver to each selling Holder, each of the underwriter(s), if
     any, and the Initial Purchaser, without charge, as many copies of the
     Prospectus (including each preliminary prospectus) and any amendment or
     supplement thereto as such Persons may reasonably request; the Company and
     the Subsidiary Guarantors hereby consent to the use of the Prospectus and
     any amendment or supplement to the Prospectus by each of the selling
     Holders and each of the underwriter(s), if any, in connection with the
     offering and the sale of the Transfer Restricted Securities in accordance
<PAGE>
 
                                      -16-

     with the terms thereof and with U.S. Federal securities laws and Blue Sky
     laws covered by the Prospectus or any amendment or supplement thereto;

             (x) enter into such agreements (including an underwriting agreement
     in form, scope and substance as is customary in underwritten offerings of
     securities of this type) and take all such other reasonable actions in
     connection therewith in order to expedite or facilitate the disposition of
     the Transfer Restricted Securities pursuant to any Registration Statement
     contemplated by this Agreement, all as may be reasonably requested by any
     Holder of Transfer Restricted Securities or the underwriter(s), if any, in
     connection with any sale or resale of Transfer Restricted Securities
     pursuant to any Registration Statement contemplated by this Agreement; and
     whether or not an underwriting agreement is entered into and whether or not
     the registration is an Underwritten Registration, the Company and the
     Subsidiary Guarantors shall (i) make such  representations and warranties
     to the Holders of such Transfer Restricted Securities and the underwriters,
     if any, with respect to the business of the Company and its Subsidiaries
     (including with respect to businesses or assets acquired or to be acquired
     by any of them), and the Shelf Registration Statement, Prospectus and
     documents, if any, incorporated or deemed to be incorporated by reference
     therein, in each case, in form, substance and scope as are customarily made
     by issuers to underwriters in underwritten offerings, and confirm the same
     if and when customarily requested; (ii) obtain opinions of counsel to the
     Company and the Subsidiary Guarantors and updates thereof (which counsel
     and opinions (in form, scope and substance) shall be reasonably
     satisfactory to the underwriters, if any, and special counsel to the
     Holders of the Transfer Restricted Securities being sold), addressed to
     each selling Holder of Transfer Restricted Securities and each of the
     underwriters, if any, covering the matters customarily covered in opinions
     requested in underwritten offerings and such other matters as may be
     reasonably requested by such underwriters, if any, and special counsel to
     Holders of Transfer Restricted Securities; (iii) use their best efforts to
     obtain customary "cold comfort" letters and updates thereof from the
     independent certified public accountants of the Company (and, if necessary,
     any other independent certified public accountants of any subsidiary of the
     Company or of any business acquired by the Company or any such subsidiary
     for which financial statements and financial data is, or is required to be,
     included in the Registration Statement),
<PAGE>
 
                                      -17-

     addressed (where reasonably possible) to each selling Holder of Transfer
     Restricted Securities and each of the underwriters, if any, such letters to
     be in customary form and covering matters of the type customarily covered
     in "cold comfort" letters in connection with underwritten offerings; (iv)
     if an underwriting agreement is entered into, the same shall contain
     indemnification provisions and procedures no less favorable to the selling
     Holders and the underwriters, if any, than those set forth in Section 8
     hereof (or such other provisions and procedures acceptable to Holders of a
     majority in aggregate principal amount of Transfer Restricted Securities
     covered by such Shelf Registration Statement and the underwriters, if any);
     and (v) deliver such documents and certificates as may be reasonably
     requested by the Holders of a majority in aggregate principal amount of the
     Transfer Restricted Securities being sold and the underwriters, if any, to
     evidence the continued validity of the representations and warranties made
     pursuant to clause (i) above and to evidence compliance with any customary
     conditions contained in the underwriting agreement or other agreement
     entered into by the Company.

          If at any time the representations and warranties of the Company and
the Subsidiary Guarantors contemplated in clause (A)(1) above cease to be true
and correct, the Company shall so advise the Initial Purchaser and the
underwriter(s), if any, and each selling Holder promptly and, if requested by
any of them, shall confirm such advice in writing;

             (xi) prior to any public offering of Transfer Restricted
     Securities, cooperate with and cause the Subsidiary Guarantors to cooperate
     with the selling Holders, the underwriter(s), if any, and their respective
     counsel in connection with the registration and qualification (or exemption
     from such registration or qualification) of the Transfer Restricted
     Securities for offer and sale under the securities or Blue Sky laws of such
     jurisdictions as the selling Holders and underwriter(s), if any, may
     reasonably request in writing and do any and all other acts or things
     necessary or advisable to enable the disposition in such jurisdictions of
     the Transfer Restricted Securities covered by the Registration Statement;
                                                                              
     provided, however, that neither the Company nor the Subsidiary Guarantors
     --------  -------                                                        
     shall be required to register or qualify as a foreign corporation where it
     is not now so qualified or to take any action that would subject it to the
     service of process or to taxation, other than as to matters and
     transactions relating to the
<PAGE>
 
                                      -18-

     Registration Statement, in any jurisdiction where it is not now so subject;

             (xii)  if a Shelf Registration is filed pursuant to Section 2(b),
     cooperate with the selling Holders of Registrable Securities and the
     managing Underwriters, if any, to facilitate the timely preparation and
     delivery of certificates representing Transfer Restricted Securities to be
     sold, which certificates shall not bear any restrictive legends and shall
     be in a form eligible for deposit with The Depository Trust Company; and
     enable such Transfer Restricted Securities to be in such denominations and
     registered in such names as the managing Underwriters, if any, or Holders
     may reasonably request;

             (xiii)  in connection with any sale or transfer of Transfer
     Restricted Securities that will result in such securities no longer being
     Transfer Restricted Securities, cooperate with and cause the Subsidiary
     Guarantors to cooperate with the selling Holders and the underwriter(s), if
     any, to facilitate the timely preparation and delivery of certificates
     representing Transfer Restricted Securities to be sold and not bearing any
     restrictive legends; and enable such Transfer Restricted Securities to be
     in such denominations and registered in such names as the Holders or the
     underwriter(s), if any, may request at least two business days prior to any
     sale of Transfer Restricted Securities made by such underwriter(s);

             (xiv)  use its best efforts to cause the Transfer Restricted
     Securities covered by the Registration Statement to be registered with or
     approved by such other governmental agencies or authorities as may be
     necessary to enable the seller or sellers of such Transfer Restricted
     Securities or the underwriter(s), if any, to consummate the disposition of
     such Transfer Restricted Securities, subject to the proviso contained in
     clause (xi) above;

             (xv) if any fact or event contemplated by Section 6(c)(iii)(D) of
     this Agreement shall exist or have occurred, prepare a supplement or post-
     effective amendment to the Registration Statement or related Prospectus or
     any document incorporated in such Registration Statement or Prospectus by
     reference or file any other required document so that, as thereafter
     delivered to the purchasers of Transfer Restricted Securities, the
     Registration Statement will not contain an untrue statement of a material
     fact or omit to state any material fact necessary to make the statements
<PAGE>
 
                                      -19-

     therein not misleading and the Prospectus will not contain an untrue
     statement of a material fact or omit to state any material fact required to
     be stated therein or necessary to make the statements contained therein, in
     the light of the circumstances under which they were made, not misleading;

             (xvi)  provide a CUSIP number for all Transfer Restricted
     Securities not later than the effective date of the Registration Statement
     and provide the Trustee under the Indenture with printed certificates for
     the Transfer Restricted Securities that are in a form eligible for deposit
     with The Depository Trust Company;

             (xvii)  cooperate and assist in any filings required to be made
     with the NASD and in the performance of any due diligence investigation by
     any underwriter (including any "qualified independent underwriter" that is
     required to be retained in accordance with the rules and regulations of the
     NASD);

             (xviii)  otherwise use its best efforts to comply with all
     applicable rules and regulations of the Commission in regards to any
     Registration Statement, and make generally available to its
     securityholders, as soon as practicable, a consolidated earning statement
     of the Company meeting the requirements of Rule 158 (which need not be
     audited) for the twelve-month period (A) commencing at the end of any
     fiscal quarter in which Transfer Restricted Securities are sold to
     underwriters in a firm commitment or reasonable best efforts Underwritten
     Offering or (B) if not sold to underwriters in such an offering, beginning
     with the first month of the Company's first fiscal quarter commencing after
     the effective date of the Registration Statement;

             (xix)  cause the Indenture to be qualified under the TIA not later
     than the effective date of the first Registration Statement required by
     this Agreement, and, in connection therewith, cooperate with the Trustee
     and the Holders to effect such changes to the Indenture, if any, as may be
     required for such Indenture to be so qualified in accordance with the terms
     of the TIA; and execute, and use its best efforts to cause the Trustee to
     execute, all customary documents that may be required to effect such
     changes and all other forms and documents required to be filed with the
     Commission to enable such Indenture to be so qualified in a timely manner.

          Each Holder agrees by acquisition of a Transfer Restricted Security
that, upon receipt of any notice from the Company of the existence of any fact
of the kind described in Section 6(c)(iii)(D) of this Agreement, such Holder
will forthwith discontinue disposition of Transfer Restricted Securities
pursuant to the applicable Registration Statement until such Holder's receipt of
the copies of the supplemented or amended Prospectus contemplated by Section
6(c)(xv) of this Agreement, or until it is advised in writing (the "Advice") by
                                                                    ------     
the Company that the use of the Prospectus may be resumed, and has received
copies of any additional or supplemental filings that are incorporated by
reference in the Prospectus.  If so directed by  the Company, each Holder will
deliver to the Company (at the Company's expense) all copies, other than
permanent file copies then in such Holder's possession, of the Prospectus
covering such Transfer Restricted Securities that was current at the time of
receipt of such notice.  In the event that the Company shall give any such
notice, the time period regarding the effectiveness of such Registration
Statement set forth in Section 3 or 4 of this Agreement, as applicable, shall be
extended by the number of days during the period from and including the date of
the giving of such notice pursuant to Section 6(c)(iii)(D) of this Agreement to
and including the date when each selling Holder covered by such Registration
Statement shall have received the copies of the supplemented or amended
Prospectus contemplated by Section 6(c)(xv) of this Agreement or shall have
received the Advice.

          SECTION 7.  REGISTRATION EXPENSES

          (a) All fees and expenses incident to the Company's and the Subsidiary
Guarantors' performance of or compliance with this Agreement will be borne by
the Company regardless of whether a Registration Statement becomes effective,
including without limitation: (i) all registration and filing fees and expenses

(including the expenses of any special audit and comfort letters required by or

          The Company and the Subsidiary Guarantors will, in any event, bear
their internal expenses (including, without limitation, all salaries and
expenses of their officers and employees performing legal or accounting duties),
the expenses of any annual audit and the fees and expenses of any Person,
including special experts, retained by them.

          SECTION 8.  INDEMNIFICATION

          (a) Each of the Company and the Subsidiary Guarantors, on a joint and
several basis, agrees to indemnify and hold harmless (i) the Initial Purchaser,
each Holder of Transfer Restricted Securities and each Participating Broker
Dealer, (ii) each person, if any, who controls any of the foregoing within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act (any of the
persons referred to in this clause (ii) being hereinafter referred to as a
                                                                          
"controlling person") and (iii) its agents, employees, officers and directors
- -------------------                                                          
and the agents, employees, officers and directors of any such controlling person
(collectively, the "Indemnified Persons") from and against any and all losses,
                    -------------------                                       
liabilities, claims, damages and expenses whatsoever (including but not limited
to reasonable attorneys' fees and any and all reasonable expenses whatsoever
incurred in investigating, preparing or defending against any litigation,
<PAGE>
 
                                      -22-

commenced or threatened, or any claim whatsoever, and any and all reasonable
amounts paid in settlement of any claim or litigation) to which they or any of
them may become subject under the Act, the Exchange Act or otherwise, insofar as
such losses, liabilities, claims, damages or expenses (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement or
Prospectus, or in any amendment thereof or supplement thereto, or arise out of
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading;
                                                                             
provided, however, that the Company and the Subsidiary Guarantors will not be
- --------  -------                                                            
liable in any such case to the extent, but only to the extent, that any such
loss, liability, claim, damage or expense arises out of or is based upon any
such untrue statement or alleged untrue statement or omission or alleged
omission made therein in reliance upon and in conformity with written
information furnished to the Company by or on behalf of any Indemnified Person
relating to such Indemnified Person expressly for use therein.  This indemnity
agreement will be in addition to any liability that the Company and the
Subsidiary Guarantors may otherwise have, including, but not limited to,
liability under this Agreement.

          If any action is brought against any Indemnified Persons or any such
person in respect of which indemnity may be sought against the Company and the
Subsidiary Guarantors pursuant to the foregoing paragraph, such Indemnified
Persons or such person shall promptly notify the indemnifying party in writing
of the institution of such action and the indemnifying party shall assume the
defense of such action, including the employment of counsel reasonably
satisfactory to such indemnified party and payment of all fees and expenses,
provided, however, except to the extent that the indemnifying party shall be
materially prejudiced thereby (through the forfeiture of substantive rights or
defenses), that the omission to so notify the indemnifying party shall not
relieve the indemnifying party from any liability which they may have to the
Indemnified Persons or any such person or otherwise.  Such Indemnified Persons
shall have the right to employ its own counsel in any such case, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Persons
unless the employment of such counsel shall have been authorized in writing by
the indemnifying party in connection with the defense of such action or the
indemnifying party shall not have employed counsel to have charge of the defense
of such action or such indemnified party or parties shall have reasonably
concluded that there may be defenses available to
<PAGE>
 
                                      -23-

it or them which are different from or additional to those available to the
indemnifying party (in which case the indemnifying party shall not have the
right to direct the defense of such action on behalf of the indemnified party or
parties), in any of which events such fees and expenses shall be borne by the
indemnifying party and paid as incurred (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (together with appropriate local counsel) in any one action or
series of related actions in the same jurisdiction representing the indemnified
parties who are parties to such action).  The indemnifying party shall not be
liable for any settlement of any such claim or action effected without its
written consent but if settled with the written consent of the indemnifying
party, the indemnifying party agrees to indemnify and hold harmless any
Indemnified Persons and any such person from and against any loss or liability
by reason of such settlement.  Notwithstanding the foregoing sentence, if at any
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel as contemplated
by the second sentence of this paragraph, then the indemnifying party agrees
that it shall be liable for any settlement of any proceeding effected without
its written consent if (i) such settlement is entered into more than 60 business
days after receipt by such indemnifying party of the aforesaid request, (ii)
such indemnifying party shall not have reimbursed the indemnified party in
accordance with such request prior to the date of such settlement and (iii) such
indemnified party shall have given the indemnifying party at least 30 days'
prior notice of its intention to settle.  No indemnifying party shall, without
the prior written consent of the indemnified party, effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such proceeding.

          (b) In connection with any Registration Statement pursuant to which a
Holder of Transfer Restricted Securities offers or sells Transfer Restricted
Securities, such Holder agrees, severally and not jointly, to indemnify and hold
harmless the Company and the Subsidiary Guarantors, their respective directors
and officers and any person controlling the Company or a Subsidiary Guarantor
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act, and each of their agents, employees, officers and directors and
the agents, employees, officers and directors of such controlling person from
<PAGE>
 
                                      -24-

and against any losses, liabilities, claims, damages and expenses whatsoever
(including but not limited to reasonable attorneys' fees and any and all
reasonable expenses whatsoever incurred in investigating, preparing or defending
against any litigation, commenced or threatened, or any claim whatsoever and any
and all reasonable amounts paid in settlement of any claim or litigation) to
which they or either of them may become subject under the Act, the Exchange Act
or otherwise insofar as such losses, liabilities, claims, damages or expenses
(or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement, or in any amendment thereof or supplement thereto, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, in each case to the extent, but only to the extent, that
any such loss, liability, claim, damage or expense arises out of or is based
upon any untrue statement or alleged untrue statement or omission or alleged
omission made therein in reliance upon and in conformity with written
information relating to such Holder furnished to the Company by such Holder
expressly for use in such Registration Statement.

          If any action is brought against the Company or the Subsidiary
Guarantors or any such person in respect of which indemnity may be sought
against any Holder of Transfer Restricted Securities pursuant to foregoing
paragraph, the Company, the Subsidiary Guarantors or such person shall promptly
notify such Holder in writing of the institution of such action and such Holder
shall assume the defense of such action, including the employment of counsel
reasonably satisfactory to such indemnified party and payment of all fees and
expenses, provided, however, except to the extent that the indemnifying party
shall be materially prejudiced thereby (through the forfeiture of substantive
rights or defenses), that the omission to so notify such Holder shall not
relieve such Holder from any liability which they may have to the Company, the
Subsidiary Guarantors or any such person or otherwise.  The Company, the
Subsidiary Guarantors or such person shall have the right to employ its own
counsel in any such case, but the fees and expenses of such counsel shall be at
the expense of the Company or such person unless the employment of such counsel
shall have been authorized in writing by such Holder of Transfer Restricted
Securities in connection with the defense of such action or such Holder shall
not have employed counsel to have charge of the defense of such action or such
indemnified party or parties shall have reasonably concluded that there may be
defenses available to it or them
<PAGE>
 
                                      -25-

which are different from or additional to those available to such Holder (in
which case such Holder shall not have the right to direct the defense of such
action on behalf of the indemnified party or parties, but such Holder may employ
counsel and participate in the defense thereof but the fees and expenses of such
counsel shall be at the expense of such Holder), in any of which events such
fees and expenses shall be borne by such Holder and paid as incurred (it being
understood, however, that such Holder shall not be liable for the expenses of
more than one separate counsel in any one action or series of related actions in
the same jurisdiction representing the indemnified parties who are parties to
such action).  Anything in this paragraph to the contrary notwithstanding, any
Holder of Transfer Restricted Securities shall not be liable for any settlement
of any such claim or action effected without the written consent of such Holder
but if settled with the written consent of such Holder, such Holder agrees to
indemnify and hold harmless the Company, the Subsidiary Guarantors and any such
person from and against any loss or liability by reason of such settlement.
Notwithstanding the foregoing sentence, if at any time an indemnified party
shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel as contemplated by the second sentence of this
paragraph, then the indemnifying party agrees that it shall be liable for any
settlement of any proceeding effected without its written consent if (i) such
settlement is entered into more than 60 business days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall
not have reimbursed the indemnifying party in accordance with such request prior
to the date of such settlement and (iii) such indemnified party shall have given
the indemnifying party at least 30 days' prior notice of its intention to
settle.  No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened proceeding
in respect of which any indemnified party is or could have been a party and
indemnity could have been sought hereunder by such indemnified party, unless
such settlement includes an unconditional release of such indemnified party from
all liability on claims that are the subject matter of such proceeding.

          (c) In order to provide for contribution in circumstances in which the
indemnification provided for in paragraphs (a) and (b) of this Section 8 is for
any reason held to be unavailable from the indemnifying party, or is
insufficient to hold harmless a party indemnified under this Section 8, the
Company, the Subsidiary Guarantors and the Indemnified Parties shall contribute
to the aggregate losses, claims, damages,
<PAGE>
 
                                      -26-

liabilities and expenses of the nature contemplated by such indemnification
provision (including any investigation, legal and other expenses incurred in
connection with, and any amount paid in settlement of, any action or any claims
asserted) to which the Company, and/or the Subsidiary Guarantors and the
Indemnified Parties may be subject, (i) in such proportion as is appropriate to
reflect the relative benefits received by the Company and the Subsidiary
Guarantors, on the one hand, and the Indemnified Parties, on the other hand,
from the offering of the Old Notes or, (ii) if such allocation is not permitted
by applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company and the Subsidiary Guarantors, on the one hand, and the Indemnified
Parties, on the other hand, in connection with the statements or omissions that
resulted in such losses, claims, damages, liabilities or expenses, as well as
any other relevant equitable considerations.  The relative  benefits received by
the Company and the Subsidiary Guarantors, on the one hand, and the Indemnified
Parties, on the other hand, shall be deemed to be in the same proportion as the
total proceeds from the offering of Old Notes (net of discounts but before
deducting expenses) received by the Company as set forth in the table on the
cover page of the Offering Memorandum bear to the total proceeds received by
such Holder with respect to its sale of Transfer Restricted Securities or New
Notes.  The relative fault of the Company and the Subsidiary Guarantors, on the
one hand, and the Indemnified Parties, on the other hand, shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company, the Subsidiary Guarantors or the
Indemnified Parties and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

          The Company, the Subsidiary Guarantors and the Initial Purchaser agree
that it would not be just and equitable if contribution pursuant to this
paragraph (c) of this Section 8 were determined by pro rata allocation or by any
other method of allocation that does not take into account the equitable
considerations referred to above.  Notwithstanding the provisions of paragraph
(c) of this Section 8, (i) in no case shall an Indemnified Party be required to
contribute any amount in excess of the amount by which the total received by
such Indemnified Party with respect to its sale of its Transfer Restricted
Securities or New Notes, as the case may be, exceeds the amount of any damages
that such Indemnified Party has otherwise been required to pay by reason of any
untrue or alleged untrue
<PAGE>
 
                                      -27-

statement or omission or alleged omission and (ii) no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  For purposes of this paragraph (c) of this
Section 8, each person, if any, who controls an Indemnified Party within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have
the same rights to contribution as such Indemnified Party, and each person, if
any, who controls the Company or the Subsidiary Guarantors within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act shall have the same
rights to contribution as the Company or the Subsidiary Guarantors, subject in
each case to clauses (i) and (ii) of this paragraph.  Any party entitled to
contribution will, promptly after receipt of notice of commencement of any
Action against such party in respect of which a claim for contribution may be
made against another party or parties under this paragraph 8(c), notify such
party or parties from whom contribution  may be sought, but, except to the
extent that the indemnifying party shall be materially prejudiced thereby
(through the forfeiture of substantive rights and defenses), the omission to so
notify such party or parties shall not relieve the party or parties from whom
contribution may be sought from any obligation it or they may have under this
paragraph (c) or otherwise.  No party shall be liable for contribution with
respect to any action or claim settled without its written consent; provided,
                                                                    -------- 
however, that such written consent was not unreasonably withheld.
- -------                                                          

SECTION 9.  RULE 144A

          The Company and the Subsidiary Guarantors shall use their best
efforts, for so long as any Transfer Restricted Securities remain outstanding,
to make available to any Holder or beneficial owner of Transfer Restricted
Securities in connection with any sale of such securities and any prospective
purchaser of such Transfer Restricted Securities from such Holder or beneficial
owner, the information required by Rule 144A(d)(4) under the Act in order to
permit resales of such Transfer Restricted Securities pursuant to Rule 144A.

SECTION 10.  PARTICIPATION IN UNDERWRITTEN REGISTRATIONS

          No Holder may participate in any Underwritten Registration under this
Agreement unless such Holder (a) agrees to sell such Holder's Transfer
Restricted Securities on the basis provided in any underwriting arrangements
approved by the Persons entitled under this Agreement to approve such
arrangements and (b) completes and executes all reasonable questionnaires,
powers
<PAGE>
 
                                      -28-

of attorneys, indemnities, underwriting agreements, lock-up letters and other
documents required under the terms of such underwriting arrangements.

SECTION 11.  SELECTION OF UNDERWRITERS

          The Holders of Transfer Restricted Securities covered by the Shelf
Registration Statement who desire to do so may sell such Transfer Restricted
Securities in an Underwritten Offering.  In any such Underwritten Offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be selected by the Holders of a majority in
aggregate principal amount of the Transfer Restricted Securities included in
such offering; provided, that such investment bankers and managers must be
               --------                                                   
reasonably satisfactory to the Company.

SECTION 12.  MISCELLANEOUS

          (a) Remedies.  Each Holder, in addition to being entitled to exercise
              --------                                                         
all rights provided in this Agreement, in the Indenture, the Purchase Agreement
or granted by law, including recovery of liquidated or other damages, will be
entitled to specific performance of its rights under this Agreement.  The
Company and the Subsidiary Guarantors agree that monetary damages would not be
adequate compensation for any loss incurred by reason of a breach by it of the
provisions of this Agreement and hereby agree to waive the defense in any Action
for specific performance that a remedy at law would be adequate.

          (b) No Inconsistent Agreements.  Each of the Company and the
              --------------------------                              
Subsidiary Guarantors will not on or after the date of this Agreement enter into
any agreement with respect to its securities that is inconsistent with the
rights granted to the Holders in this Agreement or otherwise conflicts with the
provisions of this Agreement.  The Company have not previously entered into any
agreement granting any registration rights with respect to its securities to any
Person.  The rights granted to the Holders under this Agreement do not in any
way conflict with and are not inconsistent with the rights granted to the
holders of the Company's securities under any agreement in effect on the date of
this Agreement.

          (c) Adjustments Affecting the Notes.  Without the written consent of
              -------------------------------                                 
the Holders of a majority in aggregate principal amount of outstanding Transfer
Restricted Notes, the Company and the Subsidiary Guarantors will not take any
action, or permit any change to occur, with respect to the Notes that
<PAGE>
 
                                      -29-

would materially and adversely affect the ability of the Holders to Consummate
any Exchange Offer.

          (d) Amendments and Waivers.  The provisions of this Agreement may not
              ----------------------                                           
be amended, modified or supplemented, and waivers or consents to or departures
from the provisions of this Agreement may not be given unless the Company has
obtained the written consent of Holders of a majority of the outstanding
principal amount of Transfer Restricted Securities.  Notwithstanding the
foregoing, a waiver or consent to departure from the provisions of this
Agreement that relates exclusively to the rights of Holders whose securities are
being sold or tendered pursuant to a Registration Statement and that does not
affect directly or indirectly the rights of other Holders whose securities are
not being sold or tendered pursuant to such Registration Statement may be given
by the Holders of a majority  of the outstanding principal amount of Transfer
Restricted Securities being so sold or tendered.

          (e) Notices.  All notices and other communications provided for or
              -------

shall have, independent effect, and compliance with any particular covenant,
term or provision shall not constitute compliance with any other covenants, term
or provision.

          1.03.      Accounting Principles.
                     --------------------- 

          (a)  Except as otherwise provided in this Agreement, all computations
and determinations as to accounting or financial matters and all financial
statements to be delivered pursuant to this Agreement shall be made and prepared
in accordance with GAAP (including principles of consolidation where
appropriate), and all accounting or financial terms shall have the meanings
assigned to such terms by GAAP.

          (b)  If any change in GAAP after the date of this Agreement is or
shall be required to be applied to transactions then or thereafter in existence,
and a violation of one or more provisions of this Agreement shall have occurred
or in the opinion of the Borrower would likely occur which would not have
occurred or be likely to occur if no change in accounting principles had taken
place,

            (i) The parties agree that such violation shall not be considered to
     constitute an Event of Default or a Potential Default for a period of
     ninety (90) days from the date the Borrower notifies the Administrative
     Agent of the application of this Section 1.03(b);

            (ii) The parties agree in such event to negotiate in good faith
     an amendment of this Agreement which shall approximate to the extent
     possible the economic effect of the original financial covenants after
     taking into account such change in GAAP; and

                                      -31-

            (iii)  If the parties are unable to negotiate such an amendment 
     within such ninety (90) day period, the Borrower shall have the option of
     (A) prepaying the Loans and cash collateralizing the Letters of Credit
     (pursuant to applicable provisions hereof) or (B) submitting the drafting
     of such an amendment to a firm of independent certified public accountants
     of nationally recognized standing acceptable to the parties, which shall
     complete its draft of such amendment within ninety (90) days of submission;
     if the Borrower and the Agents cannot agree, the firm shall be selected by
     binding arbitration in the City of Pittsburgh, Pennsylvania in accordance
     with the rules then and there obtaining of the American Arbitration
     Association. If the Borrower does not exercise either such option within
     said period, then as used in this Agreement "GAAP" shall mean generally
     accepted accounting principles in effect at the Relevant Date. The parties
     agree that if the Borrower elects the option in clause (B) above, until
     such firm has been selected and completes drafting such amendment, no such
     violation shall constitute an Event of Default or a Potential Default.

          (c)  If any change in GAAP after the date of this Agreement is
required to be applied to transactions or conditions then or thereafter in
existence, and the Agents shall assert that the effect of such change is or
shall likely be to distort materially the effect of any of the definitions of
financial terms in Article I or any of the covenants of the Borrower in Section
7.01 (the "Financial Maintenance Covenants"), so that the intended economic
effect of any of the Financial Maintenance Covenants will not in fact be
accomplished,

               (i) The Administrative Agent shall notify the Borrower of such
     assertion, specifying the change in GAAP which is objected to, and, until
     otherwise determined as provided below, the specified change in GAAP shall
     not be made by the Borrower in its financial statements for the purpose of
     applying the Financial Maintenance Covenants;

               (ii) The parties shall follow the procedures set forth in
     paragraph (ii) and the first sentence of paragraph (iii) of subsection (b)
     of this Section.  If the parties are unable to agree on an amendment as
     provided in said paragraph (ii) and if the Borrower does not exercise
     either option set forth in the first sentence of said paragraph (iii)
     within the specified period, then as used in this Agreement "GAAP" shall
     mean generally accepted accounting principles in effect at the Relevant
     Date, except that the specified change in GAAP which is objected to by the
     Agents shall not be made in applying the Financial Maintenance Covenants.
     The parties agree that if the Borrower elects the option in clause (B) of
     the first sentence of said paragraph (iii), until such independent firm has
     been selected and completes drafting such amendment, the specified change
     in GAAP shall not be made in applying the Financial Maintenance Covenants;
     and

            (d)  All expenses of compliance with this Section 1.03 shall be paid
by the Borrower.

            1.04.    Currency Equivalents Generally.
                     ------------------------------ 

          For all purposes of any Loan or Letter of Credit (or the making or
issuance thereof) pursuant to this Agreement (but not for purposes of the
preparation of any financial statements delivered pursuant hereto), the
equivalent in Australian Dollars (the "Australian Dollar Equivalent") of an
amount in U.S. Dollars, and the equivalent in U.S. Dollars (the "U.S. Dollar
Equivalent") of an amount in Australian Dollars or other currency, shall be
determined at the Spot Rate; provided that the U.S. Dollar Equivalent of an
amount denominated in U.S. Dollars shall be such amount.  For purposes of
determining compliance with any restriction determined by reference to a U.S.
Dollar amount in this Agreement (other than to the extent relating to any Loan
or Letter of Credit (or the making or issuance thereof) under this Agreement),
the U.S. Dollar Equivalent amount of transactions occurring prior to the date of
determination shall be calculated based on the Spot Rate on the date of
determination; provided that such restriction shall nonetheless be deemed not
violated if the U.S. Dollar Equivalent amount of such transactions based on the
Spot Rate in effect on the respective dates of such transactions would have been
in compliance with the applicable restriction.

each of the Term Loan A Facility, the Term Loan B Facility and the Revolving
Credit Facility at any given time shall be equal to the amount set forth in
Annex A (or in any Commitment and Loan Transfer Supplement) as its "Term Loan A
Committed Amount," "Term Loan B Committed Amount" or "Revolving Credit Committed
Amount," as the case may be, as any such amounts may have been reduced pursuant
to Section 2.05(b) at such time, and subject to transfer as provided in Section
10.12.  The Committed Amount of each Bank with respect to the Loans shall at all
times be in the Proportion set forth opposite the name of each such Bank in
Annex A (or in any Commitment and Loan Transfer Supplement) as its "Term Loan A
Proportion," "Term Loan B Proportion" or "Revolving Credit Proportion," as the
case may be.

conditions and relying upon the representations and warranties herein set forth,
each Bank with a Revolving Credit Committed Amount, severally and not jointly,
agrees (each such agreement being herein called a "Revolving Credit Commitment")
to make loans to the Borrower (the "Revolving Credit Loans") and to otherwise
extend credit to the Borrower in the form of deemed participations in the
Australian Term Loan Letter of Credit, Australian Revolving Loan Letter of
Credit, Standby or Trade Letters of Credit, or as otherwise contemplated by
Article III hereof, at any time or from time to time on or after the Closing
Date and to but not including the Revolving Credit Expiration Date.  A Bank
shall have no obligation to make any Revolving Credit Loan to the extent that
(A) the aggregate of all Revolving Credit Loans of such Bank which are
outstanding plus the aggregate of all Letter of Credit Participating Interests
of such Bank in outstanding Standby or Trade Letters of Credit exceed such
Bank's Pro Rata Share (based on such Bank's Revolving Credit Proportion) of
$80,000,000 plus the amount of any Letter of Credit Participating Interests in
any Letter of Credit Unreimbursed Draw in respect of the Australian Term Loan
Letter of Credit and the Australian Revolving Loan Letter of Credit; or (B) such
Bank's Revolving Credit Exposure at any time would exceed such Bank's Revolving
Credit Committed Amount at such time.  Further, the Banks shall have no

Expiration Date.  To the extent not due and payable earlier as provided herein,
Revolving Credit Loans shall be due and payable on the Revolving Credit

     Borrower (the "Term Loan A Facility Term Loans") at any time or from time
     to time on or after the Closing Date and to but not including the Term Loan
     A Commitment Expiration Date.  A Bank shall have no obligation to make any
     Term Loan A Facility Term Loan to the extent that the sum of such Bank's
     Pro Rata share of the aggregate principal amount of Term Loan A Facility
     Term Loans would at any time exceed such Bank's Term Loan A Committed
     Amount less such Bank's Pro Rata share of all repayments, prepayments and
     Scheduled Amortization Payments applied to the Term Loan A Facility.  Each

     Loans following any repayment, prepayment or Scheduled Amortization Payment

     Borrower (the "Term Loan B Facility Term Loans") on the Closing Date in an
     aggregate principal amount equal to such Bank's Pro Rata share of the
     aggregate principal amount of the Term Loan B Facility.  Such agreement
     shall terminate on the Closing Date to the extent that the Term Loan B
     Facility Term Loans have not been made.  To the extent not due and payable
     earlier as provided herein, Term Loan B Facility Term Loans shall be due
     and payable on the Term Loan B Expiration Date.  The Borrower may not
     reborrow Term Loan B Facility Term Loans following any repayment,
     prepayment or Scheduled Amortization Payment with respect thereto.

     declining Bank's prepayment share shall be applied Pro Rata (as provided
     above) to the Term Loan A Facility and the Australian Term Loan Facility,

         (E)  The Borrower shall pay in respect of the Term Loan A Facility, the
     Term Loan B Facility and, to the extent provided in the next succeeding
     sentence, the Revolving Credit Facility, and shall cause KAP to pay,
     subject to the next succeeding sentence, in respect of the Australian Term
     Loan Facility, each Scheduled Amortization Payment until all Term Loans,
     borrowings under the Australian Term Loan Facility and Letter of Credit
     Unreimbursed Draws in respect of the Australian Term Loan Letter of Credit
     are paid in full, in the amounts and at the times specified in the
     definition of Scheduled Amortization Payment to the extent that prepayments
     have not previously been applied to such Scheduled Amortization Payments
     pursuant to the terms hereof; provided that any Scheduled Amortization
     Payment in respect of the Australian Term Loan Facility shall be net of the
     amount of any reduction in the Letter of Credit Undrawn Availability of the
     Australian Term Loan Letter of Credit attributable to a reduction in the
     Australian Term Loan Interest Reserve related to a Scheduled Amortization
     Payment under the Australian Term Loan Facility.  Any Scheduled
     Amortization Payment in respect of the Australian Term Loan Facility shall
     be applied Pro Rata (treating the Australian Term Loan Facing Bank as a
     Bank having a Proportion equal to the amount outstanding under the
     Australian Term Loan Facility) towards amounts outstanding under the
     Australian Term Loan Facility and amounts outstanding under the Revolving
     Credit Facility in respect of, and only to the extent of, Letter of Credit
     Participating Interests in any Letter of Credit Unreimbursed Draw under the
     Australian Term Loan Letter of Credit.  The Committed Amount of each Bank
     with respect to the Term Loan A Facility, the Term Loan B Facility or the

                                      -40-

     Revolving Credit Facility, as the case may be, shall be Pro Rata
     automatically and permanently reduced to the extent of any payment applied
     to such facility under this Section and the Revolving Credit Committed
     Amount of each Bank shall also be Pro Rata automatically and permanently
     reduced as provided in Section 3.01(b)(i).

         (ii) Revolving Facility.  (A)  As provided in the next succeeding
              ------------------                                          
     sentence, the Borrower shall prepay Swingline Loans and Revolving Credit
     Loans and shall provide cash collateral with respect to outstanding Letter
     of Credit Exposure to the extent that the aggregate Revolving Credit
     Exposure exceeds the aggregate Revolving Credit Committed Amounts.

         Such excess amount shall be applied first to the principal of Swingline
     Loans, then to the principal of the Revolving Credit Loans, then to
     outstanding Letter of Credit Unreimbursed Draws, and the balance shall be
     deposited into the Letter of Credit Collateral Account.

         The Borrower shall cause KAP to pay all amounts owing in respect of
     KAP's obligations under the Australian Revolving Loan Facility, including
     repayment of all outstanding borrowings thereunder, on or prior to the
     Revolving Credit Expiration date.

         (B)  The Borrower shall prepay or repay any Letter of Credit
     Participating Interests in any Letter of Credit Unreimbursed Draw under the
     Australian Term Loan Letter of Credit in accordance with Sections
     2.05(c)(i)(D), 2.05(c)(i)(E) and 2.08(c) of this Agreement.

         2.06. Interest Rates.
               -------------- 

         (a)  Optional Bases of Borrowing.  The unpaid principal amount of the
              ---------------------------                                     
Loans shall bear interest for each day until due on one or more bases selected
by the Borrower from among the interest rate Options set forth below, it being
understood that, subject to the provisions of this Agreement, including but not
limited to Section 3.11 hereof as to Swingline Loans, and so long as the
aggregate number of Funding Segments of the Euro-Rate Portion of the Loans at
any time shall not exceed twelve, the Borrower may select different Options to
apply simultaneously to different Portions of the Loans and may select different
Funding Segments to apply simultaneously to different parts of the Euro-Rate
Portion of the Loans:

         (i) Base Rate Option:  A rate per annum (computed on the basis of a
             ----------------                                               
     year of 365 or 366 days, as the case may be, and actual days elapsed) for
     each day equal to the Base Rate for such day plus the Applicable Margin for
     such day, such interest
<PAGE>
 
                                      -41-

     rate to change automatically from time to time effective as of the
     effective date of each change in the Base Rate.  "Base Rate," as used
     herein, shall mean, for any day, the greater of (A) the Prime Rate for such
     day and (B) 1/2% over the Federal Funds Effective Rate for such day, such
     interest rate to change automatically from time to time effective as of the
     effective date of each change in the Prime Rate or Federal Funds Effective
     Rate.  "Prime Rate," as used herein, shall mean the interest rate per annum
     announced from time to time by the Administrative Agent as its prime rate,
     such rate to change automatically effective as of the effectiveness of each
     announced change in such prime rate.  The Prime Rate may be greater or less
     than the interest rates charged by the Administrative Agent (in its
     capacity as a lender) to other borrowers and is not solely based or
     dependent upon the interest rate which the Administrative Agent (in such
     capacity) may charge any particular borrower or class of borrowers.
     "Federal Funds Effective Rate," as used herein, shall mean, for any day,
     the rate per annum (rounded upward to the nearest 1/100 of 1%) announced by
     the Federal Reserve Bank of New York (or any successor) as being the
     weighted average of the rates on overnight Federal funds transactions
     arranged by Federal funds brokers on the previous trading day, as computed
     and announced by such Federal Reserve Bank (or any successor) in
     substantially the same manner as such Federal Reserve Bank computes and
     announces the weighted average it refers to as the "Federal Funds Effective
     Rate" as of the date of this Agreement; provided that if such Federal
     Reserve Bank (or its successor) does not announce such rate for any day,
     the "Federal Funds Effective Rate" for such day shall be the average rate
     determined in good faith by the Administrative Agent (which determination
     shall be conclusive absent manifest error) that it was charged for its
     Federal funds transactions on such previous trading day.

            (ii) Euro-Rate Option:  A rate per annum (based on a year of 360
                 ----------------                                           
     days and actual days elapsed) for each day equal to the Euro-Rate for such
     day plus the Applicable Margin.  "Euro-Rate," as used herein, shall mean,
     for any day, for each Funding Segment of the Euro-Rate Portion
     corresponding to a proposed or existing Euro-Rate Funding Period, the rate
     per annum determined by the Administrative Agent by dividing (the resulting
     quotient to be rounded upward to the nearest 1/100 of 1%) (A) the rate of
     interest (which shall be the same for each day in such Euro-Rate Funding
     Period) determined in good faith by the Administrative Agent (which
     determination shall be conclusive absent manifest error) to be the average
     of the rates per annum for deposits in Dollars offered to major money
     center banks in the London interbank market at approximately 11:00 a.m.,
     London time, two (2) London Business Days prior to the first day of such
     Euro-Rate Funding Period for delivery on the first day of such Euro-Rate
     Funding Period in amounts comparable to such Funding Segment and having
     maturities comparable to such Euro-Rate Funding Period by (B) a number
     equal to 1.00 minus the Euro-Rate Reserve Percentage.
<PAGE>
 
                                      -42-

     The "Euro-Rate" may also be expressed by the following formula:

                     [average of the rates offered to major money
                     center banks in the London interbank market]
      Euro-Rate =    determined by the Administrative Agent per subsection (A) ]
                     ----------------------------------------------------------
                     [1.00 - Euro-Rate Reserve Percentage        ]

     The "Euro-Rate Reserve Percentage" for any day shall mean the maximum
     effective percentage (expressed as a decimal fraction, rounded upward to
     the nearest 1/100 of 1%), as determined in good faith by the Administrative
     Agent (which determination shall be conclusive absent manifest error),
     which is in effect on such day as prescribed by the Board of Governors of
     the Federal Reserve System (or any successor) for determining the reserve
     requirements (including supplemental, marginal and emergency reserve
     requirements) with respect to eurocurrency funding (currently referred to
     as "Eurocurrency liabilities") of a member bank in such System.  The Euro-
     Rate shall be adjusted automatically as of the effective date of each
     change in the Euro-Rate Reserve Percentage.  The Euro-Rate shall be
     calculated in accordance with the foregoing whether or not any Bank is
     actually required to hold reserves in connection with its eurocurrency
     funding or, if it is required to hold reserves, is required to hold
     reserves at the "Euro-Rate Reserve Percentage" as herein defined.  The
     Administrative Agent shall give promptly notice to the Borrower and to the
     Banks of the Euro-Rate so determined or adjusted, which determination or
     adjustment, if made in good faith, shall be conclusive absent manifest
     error.

            (iii)  As-Offered Rate Option:  A rate per annum (computed on the
                   ----------------------                                    
     basis of a year of 365 or 366 days, as the case may be, and actual days
     elapsed) equal to the As-Offered Rate for such day plus the Applicable
     Margin.  "As-Offered Rate," as used herein, shall mean, for any day, for
     each Funding Segment of the As-Offered Rate Portion corresponding to a
     proposed or existing As-Offered Rate Funding Period, a rate per annum
     offered by the Swingline Bank in its sole discretion to Borrower from time
     to time.

Notwithstanding the foregoing, Term Loan A Facility Term Loans and Revolving
Credit Loans may be made only at the Base Rate Option and the Euro-Rate Option,
Term Loan B Facility Term Loans may be made only at the Euro-Rate Option and
Swingline Loans may be made only at the Base Rate Option and the As-Offered Rate
Option.

          "Applicable Margin" is based on the applicable Pricing Level and shall
mean for each Option the rate per annum set forth below:

provided, that through the first day of the calendar month following the first
determination of the Performance Ratio, the Applicable Margin shall equal (i)
175 basis points in respect of Euro-Rate based and As-Offered Rate based Loans
which are Term Loan A Facility Term Loans and Revolving Credit Loans (including
Swingline Loans), (ii) 225 basis points in respect of Euro-Rate based Loans
which are Term Loan B Facility Term Loans and (iii) 75 basis points in respect
of Base Rate based Loans.  Together with each delivery of financial statements
pursuant to Section 6.01(a) or 6.01(b), the Borrower shall deliver a
certificate, duly completed and signed by the Treasurer, Controller or Chief
Financial Officer of Borrower, setting forth the calculation of the Performance
Ratio, as supported by the
<PAGE>
 
                                      -44-

accompanying financial statements, stating the Pricing Level applicable to such
Performance Ratio and calculating the U.S. Dollar Equivalent of the Revolving
Credit Exposure.  Except as expressly set forth herein, any change in the
applicable Pricing Level shall be effective as of the first day of the calendar
month following the month in which the applicable financial statements and
certificate are received by the Administrative Agent.

          (c)  Funding Periods.  Any time the Borrower shall select, convert to
               ---------------                                                 
or renew the Euro-Rate Option or the As-Offered Rate Option to apply to any part
of the Loans, the Borrower shall specify, with respect to the Euro-Rate Option,
one or more periods of one, two, three or six months (the "Euro-Rate Funding
Periods"), and, with respect to the As-Offered Rate Option, one or more periods
of days (the "As-Offered Rate Funding Period") during which such Option shall
apply; provided, that:

          (i)   Each Euro-Rate Funding Period shall begin on a London Business
     Day, and the duration of each Euro-Rate Funding Period shall be determined
     in accordance with the definition of the term "month" herein;

          (ii)  The Borrower may not select a Euro-Rate Funding Period or an
     As-Offered Rate Funding Period that would end after the Revolving Credit
     Expiration Date, the Term Loan A Expiration Date or the Term Loan B
     Expiration Date, as the case may be;

          (iii) The Borrower shall, in selecting any Euro-Rate Funding Period
     or any As-Offered Rate Funding Period, allow for foreseeable mandatory
     prepayment of the Loans; and

          (iv)  The Borrower may not select an As-Offered Rate Funding Period
     longer than 30 days.

          (d)  Transactional Amounts.  Subject to Section 3.11 hereto as to
               ---------------------                                       
Swingline Loans, every selection of, conversion from, conversion to, or renewal
of, an interest rate Option, and every payment or prepayment of any Loans
(except pursuant to Section 2.05(c)) shall be in a principal amount such that,
after giving effect thereto, the aggregate principal amount of each Portion
shall be equal to $1,000,000 or an integral multiple thereof.

          (e)  Interest After Maturity.  After the principal amount of the Base
               -----------------------                                         
Rate Portion of any Loan shall have become due (by acceleration or otherwise),
such Portion shall bear interest for each day until paid (before and after
judgment) at a rate per annum (based on a year of 365 or 366 days, as the case
may be) which shall be 2% above the then current Base Rate Option, such interest
rate to change automatically from time to time effective as of the effective
date of each change in the Base Rate.  After the principal amount of any Euro-
<PAGE>
 
                                      -45-

Rate Portion or any As-Offered Rate Portion of any Loan shall have become due
(by acceleration or otherwise), such Portion shall bear interest for each day
until paid (before and after judgment) (i) until the end of the then current
Euro-Rate Funding Period or As-Offered Rate Funding Period, as the case may be,
at a rate per annum 2% above the rate otherwise applicable to such Loan and (ii)
thereafter in accordance with the previous sentence.

          (f)  Euro-Rate Unascertainable; Impracticability.  If
               -------------------------------------------     

          (i) on any date on which a Euro-Rate would otherwise be set the
     Administrative Agent (in the case of (A) or (B) below) or any Bank (in the
     case of (C) below) shall have in good faith determined (which determination
     shall be conclusive) that:

                (A) adequate and reasonable means do not exist for ascertaining
          such Euro-Rate, or

                (B) a contingency has occurred which materially and adversely
          affects the interbank Eurodollar market, or

                (C) the effective cost to such Bank of funding a proposed
          Funding Segment of the Euro-Rate Portion from a Corresponding Source
          of Funds shall exceed the Euro-Rate applicable to such Funding
          Segment, or

          (ii) at any time any Bank shall have determined in good faith (which
     determination shall be conclusive) that the making, maintenance or funding
     of any part of the Euro-Rate Portion has been made impracticable or
     unlawful by compliance by such Bank or a Notional Euro-Rate Funding Office
     in good faith with any Law or guideline or interpretation or administration
     thereof by any Official Body charged with the interpretation or
     administration thereof or with any request or directive of any such
     Official Body (whether or not having the force of law);

then, and in any such event, the Administrative Agent or such Bank (the
"Affected Party"), as the case may be, may notify the Borrower of such
determination (and any Bank giving such notice shall so notify the
Administrative Agent).  Upon such date as shall be specified in such notice
(which shall not be earlier than one (1) Business Day following the date such
notice is given), the obligation of the Banks or the Affected Party to allow the
Borrower to select, convert to or renew the Euro-Rate Option shall be suspended
until the Administrative Agent or such Affected Party, as the case may be, shall
have later notified the Borrower (and any Affected Party giving such notice
shall so notify the Administrative Agent) of the Administrative Agent's or such
Affected Party's determination in good faith (which determination shall be
conclusive) that the circumstance giving rise to such previous
<PAGE>
 
                                      -46-

determination no longer exists.  If any Affected Party notifies the Borrower of
a determination under subsection (ii) of this Section 2.06(f), the Euro-Rate
Portion of the Loans of such Affected Party shall automatically be converted to
the Base Rate Option as of the date specified in such notice (and accrued
interest thereon shall be due and payable on such date).

          If at the time the Administrative Agent or any Bank makes a
determination under subsection (i) or (ii) of this Section 2.06(f) the Borrower
has previously notified the Administrative Agent that it wishes to select,
convert to or renew the Euro-Rate Option with respect to any proposed Loan, but
such Loan has not yet been made, such notification shall be deemed to provide
for selection of, conversion to or renewal of the Base Rate Option instead of
the Euro-Rate Option with respect to such Loan or, in the case of a
determination by a Bank, the Loan of such Bank.

          2.07.  Conversion or Renewal of Interest
               Rate Options.
               ---------------------------------

          (a)  Conversion or Renewal.  Subject to Section 3.11 hereof as to
               ---------------------                                       
Swingline Loans, and subject to the provisions of Section 2.11(b), the Borrower
may convert any part of its Loans from any interest rate Option or Options to
any other interest rate Option or Options and may renew the Euro-Rate Option as
to any Funding Segment of the Euro-Rate Portion:

          (i) At any time with respect to conversion from the Base Rate
     Option; or

          (ii) At the expiration of any Euro-Rate Funding Period with respect
     to conversions from or renewals of the Euro-Rate Option, as to the Funding
     Segment corresponding to such expiring Euro-Rate Funding Period.

          Whenever the Borrower desires to convert or renew any interest rate
Option or Options, the Borrower shall provide to the Administrative Agent
Standard Notice setting forth the following information:

          (w)  The date, which shall be a Business Day, on which the proposed
     conversion or renewal is to be made;

          (x)  The principal amounts selected in accordance with Section 2.06(d)
     of the Base Rate Portion and each Funding Segment of the Euro-Rate Portion
     to be converted from or renewed;
<PAGE>
 
                                      -47-

          (y)  The interest rate Option or Options selected in accordance with
     Section 2.06(a) and the principal amounts selected in accordance with
     Section 2.06(d) of the Base Rate Portion and each Funding Segment of the
     Euro-Rate Portion to be converted to; and

          (z)  With respect to each Funding Segment to be converted to or
     renewed, the Euro-Rate Funding Period selected in accordance with Section
     2.06(d) to apply to such Funding Segment.

Standard Notice having been so provided, after the date specified in such
Standard Notice, interest shall be calculated upon the principal amount of the
Loans as so converted or renewed.  Interest on the principal amount of any part
of Loans converted or renewed shall be due and payable on the conversion or
renewal date.

          (b)  Failure to Convert or Renew.  Absent due notice from the Borrower
               ---------------------------                                      
of conversion or renewal in the circumstance described in Section 2.07(a)(ii),
any part of the Euro-Rate Portion for which such notice is not received shall be
converted automatically to the Base Rate Option on the last day of the expiring
Euro-Rate Funding Period.

          2.08.  Payments and Prepayments.
                 ------------------------ 

          (a)  The Borrower shall have the right at its option to prepay the
Loans in whole or part without premium or penalty (but subject to the provisions
of Section 2.11(b)):

          (i) At any time with respect to any part of the Base Rate Portion; or

          (ii) At the expiration of any Euro-Rate Funding Period or any As-
     Offered Rate Funding Period with respect to prepayment of the Euro-Rate
     Portion or the As-Offered Rate Portion, as the case may be, with respect to
     any part of the Funding Segment corresponding to such expiring Euro-Rate
     Funding Period or As-Offered Rate Funding Period, as the case may be.

          If at any time the aggregate Revolving Credit Exposure shall exceed
the aggregate Revolving Credit Committed Amounts, the Borrower shall immediately
prepay a principal amount of Revolving Credit Loans as provided in Section
2.05(c)(ii).

          (b)  Subject to Section 3.11 hereto as to Swingline Loans, whenever
the Borrower desires or is required to prepay any part of the Loans, it shall
provide Standard Notice to the Administrative Agent setting forth the following
information:
<PAGE>
 
                                      -48-

            (i)   The date, which shall be a Business Day, on which the proposed
     prepayment is to be made;

            (ii)  The principal amounts selected in accordance with Section
     2.06(d) of the Base Rate Portion and each part of each Funding Segment of
     the Euro-Rate Portion to be prepaid;

            (iii) The total principal amount of such prepayment, selected in
     accordance with Section 2.06(d), which shall be the sum of the principal
     amounts of the Loans to be prepaid; and

            (iv)  The amount of such prepayment to be applied to the Term Loans
     (including amounts outstanding under the Australian Term Loan Facility) and
     the amount of such prepayment to be applied to Revolving Credit Loans.

Standard Notice having been so provided, on the date specified in such Standard
Notice the principal amounts of the Base Rate Portion and each part of the Euro-
Rate Portion specified in such notice, together with interest on such principal
amounts to such date, shall be due and payable.

          (c)  Prepayments to be applied to Term Loans pursuant to this Section
2.08 shall be applied Pro Rata (treating the Australian Term Loan Facing Bank as
a Bank having a Proportion equal to the amount outstanding under the Australian
Term Loan Facility) towards amounts outstanding under the Term Loan A Facility,
the Term Loan B Facility and the Australian Term Loan Facility based on the
aggregate principal amount outstanding thereunder and towards the Revolving
Credit Facility in respect of, and only to the extent of, amounts outstanding
thereunder due to any Letter of Credit Participating Interests in any Letter of
Credit Unreimbursed Draw under the Australian Term Loan Letter of Credit,
provided that a Bank entitled to receive a prepayment in respect of a Term Loan
B Facility Term Loan may decline such prepayment, in which case such declining
Bank's prepayment share shall be applied Pro Rata (as provided above) to the
Term Loan A Facility and the Australian Term Loan Facility, up to the full
amount outstanding thereunder and to the Revolving Credit Facility up to, and
only to the extent of, amounts outstanding thereunder due to any Letter of
Credit Participating Interests in any Letter of Credit Unreimbursed Draw under
the Australian Term Loan Letter of Credit.  Any application under this Section
2.08(c) shall be applied pro rata towards the remaining Scheduled Amortization
Payments under the Term Loan A Facility, the Term Loan B Facility and/or the
Australian Term Loan Facility, as the case may be.  The Committed Amount of each
Bank with respect to the Term Loan A Facility, the Term Loan B Facility or the
Revolving Credit Facility, as the case may be, shall be Pro Rata automatically
and permanently reduced to the extent of any payment applied to such facility
under this Section and the Revolving Credit Committed Amount of each Bank
<PAGE>
 
                                      -49-

shall also be Pro Rata automatically and permanently reduced as provided in
Section 3.01(b)(i).

          2.09.  Interest Payment Dates.
                 ---------------------- 

          Interest on the Base Rate Portion shall be due and payable on each
March 31, June 30, September 30 and December 31.  Interest on each Funding
Segment of the As-Offered Rate Portion shall be due and payable on the last day
of the corresponding As-Offered Rate Funding Period.  Interest on any Funding
Segment of the Euro-Rate Portion shall be due and payable on the last day of the
corresponding Euro-Rate Funding Period and, if such Euro-Rate Funding Period is
longer than three months, also every third month during such Euro-Rate Funding
Period.  After maturity of any part of the Loans (by acceleration or otherwise),
interest on such part shall be due and payable on demand.

          2.10.  Pro Rata Treatment and Payments.
                 ------------------------------- 

          Each borrowing from the Banks, each conversion or renewal of any
interest rate Option and each payment or prepayment to the Banks (except as
otherwise specifically provided herein, including with respect to borrowings in
respect of the Swingline Loans) shall be made Pro Rata (which, in the case of
prepayments of Term Loans, shall treat the Australian Term Loan Facing Bank as a
Bank having a Proportion equal to the amount outstanding under the Australian
Term Loan Facility) and from and to each Bank on the same date. All payments and
prepayments to be made in respect of principal, interest, fees or other amounts
due from the Borrower hereunder or under any Related Document (other than the
Australian Credit Facilities) shall be payable at 12:00 Noon, Pittsburgh time,
on the day when due without presentment, demand, protest or notice of any kind,
all of which are hereby expressly waived, and a cause of action therefor shall
immediately accrue. Except for payments under Section 2.11, 2.12 or 10.06 or in
respect of the Australian Credit Facilities, such payments shall be made to the
Administrative Agent at its Office in Dollars in funds immediately available at
such Office without setoff, counterclaim or other deduction of any nature, and
payments under Section 2.11, 2.12 or 10.06 shall be made to the applicable Bank,
Issuing Bank or the Swingline Bank at such domestic account as it may specify to
the Borrower from time to time in funds immediately available at such account.
Any payment received by the Administrative Agent or any Bank, any Issuing Bank
or the Swingline Bank after 12:00 noon, Pittsburgh time, on any day shall be
deemed to have been received on the next succeeding Business Day. The
Administrative Agent shall distribute to the Banks, the Issuing Banks or the
Swingline Bank, as the case may be, all such payments received by the
Administrative Agent for their respective accounts as promptly as practicable
after receipt by the Administrative Agent. To the extent permitted by law, after
there shall have become due (by acceleration or otherwise) interest, fees or any
other amounts due from
<PAGE>
 
                                      -50-

the Borrower hereunder or under any of the Related Documents (other than the
Australian Credit Facilities) (excluding overdue principal, which shall bear
interest as described in Section 2.06(e), but including interest payable under
this Section 2.10), such amounts shall bear interest for each day until paid
(before and after judgment), payable on demand, at a rate per annum (based on a
year of 365 or 366 days, as the case may be, and actual days elapsed) 2% above
the then current Base Rate Option, such interest rate to change automatically
from time to time effective as of the effective date of each change in the Base
Rate. To the extent permitted by law, interest accrued on any amount which has
become due hereunder or under any Related Document (other than the Australian
Credit Facilities) shall compound on a day-by-day basis, and hence shall be
added daily to the overdue amount to which such interest relates.

          All payments and prepayments, including Scheduled Amortization
Payments, required to be made hereunder in respect of borrowings under the
Australian Credit Facilities shall be payable as provided in the Australian
Credit Facilities, on the day when due without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived.  Such payments, to
the extent not determined in Australian Dollars, shall be in the amount of the
Australian Dollar Equivalent, and shall be made by KAP to both the Australian
Term Loan Facing Bank or the Australian Revolving Loan Facing Bank, as the case
may be, as provided in the Australian Credit Facilities in immediately available
Australian Dollar funds without setoff, counterclaim or other deduction of any
nature.

          2.11.  Additional Compensation in Certain Circumstances.
                 ------------------------------------------------ 

          (a)  Increased Costs or Reduced Return Resulting from Taxes, Reserves,
               -----------------------------------------------------------------
Capital Adequacy Requirements, Expenses, Etc.  If any Law or guideline or
- --------------------------------------------                             
interpretation or application thereof by any Official Body charged with the
interpretation or administration thereof or compliance with any request or
directive of any Official Body (whether or not having the force of law) now
existing or hereafter adopted:

            (i) subjects any Bank Party or any Notional Euro-Rate Funding Office
     to any tax or changes the basis of taxation with respect to this Agreement,
     the Notes, the Loans, the Letters of Credit, the Letter of Credit
     Participating Interests or the Swingline Loan Participating Interests, or
     payments by the Borrower of principal, interest, fees or other amounts due
     from the Borrower hereunder or under the Related Documents (except for
     taxes on the overall net income of such Bank Party or such Notional Euro-
     Rate Funding Office imposed by the jurisdiction in which such Bank Party's
     principal office or Notional Euro-Rate Funding Office is located),

            (ii) imposes, modifies or deems applicable any reserve, special
     deposit, insurance assessment or similar requirement against credits or
     commitments to extend credit extended by, assets (funded or contingent) of,
     deposits with or for the account
<PAGE>
 
                                      -51-

     of, or other acquisitions of funds by, such Bank Party or any Notional
     Euro-Rate Funding Office (other than requirements expressly included herein
     in the determination of the Euro-Rate hereunder),

            (iii)  imposes, modifies or deems applicable any capital adequacy or
     similar requirement (A) against assets (funded or contingent) of, or
     credits or commitments to extend credit extended by, any Bank Party or any
     Notional Euro-Rate Funding Office, or (B) otherwise applicable to the
     obligations of any Bank Party or any Notional Euro-Rate Funding Office
     under this Agreement, or

            (iv) imposes upon any Bank Party or any Notional Euro-Rate Office
     any other condition or expense with respect to this Agreement or the
     Related Documents or its making, maintenance or funding of any Loan, Letter
     of Credit, Letter of Credit Participating Interest or Swingline Loan
     Participating Interest, or any security therefor,

and the result of any of the foregoing is to increase the cost to, reduce the
income receivable by, or impose any expense (including loss of margin) upon any
Bank Party or any Notional Euro-Rate Funding Office or, in the case of clause
(iii), any person controlling a Bank Party, with respect to this Agreement, the
Related Documents or the making, maintenance or funding of any Loan, Letter of
Credit or Letter of Credit Participating Interest or Swingline Loan
Participating Interest (or, in the case of any capital adequacy or similar
requirement, to have the effect of reducing the rate of return on such Bank
Party's or controlling person's capital, taking into consideration such Bank
Party's or controlling person's policies with respect to capital adequacy) by an
amount which such Bank Party deems to be material (such Bank Party being deemed
for this purpose to have made, maintained or funded each Funding Segment of the
Euro-Rate Portion from a Corresponding Source of Funds), such Bank Party may
from time to time notify the Borrower of the occurrence of any such event and
the amount determined in good faith (using any averaging and attribution method)
by such Bank Party (which determination shall be conclusive) to be necessary to
compensate such Bank Party or such Notional Euro-Rate Funding Office for such
increase, reduction or imposition.  Such amount shall be due and payable by the
Borrower to such Bank Party ten (10) Business Days after such notice is given by
such Bank Party to the Borrower.  If requested by the Borrower, such Bank Party
shall deliver to the Borrower a certificate, which certificate shall be
conclusive absent manifest error, as to the amount due and payable under this
Section 2.11(a) from time to time and the method of calculating such amount.

          (b)  Indemnity.  In addition to the compensation required by
               ---------                                              
subsection (a) of this Section 2.11, the Borrower shall indemnify each Bank
against any loss or expense 
<PAGE>
 
                                      -52-

(including loss of margin) which such Bank has sustained or incurred as a
consequence of any:

            (i)   payment or prepayment or conversion of any Funding Segment of
     any Euro-Rate Portion or any As-Offered Rate Portion on a day other than
     the last day of the corresponding Euro-Rate Funding Period or As-Offered
     Rate Funding Period, as the case may be (whether or not such payment,
     prepayment or conversion is mandatory or automatic and whether or not such
     payment, prepayment or conversion is then due),

            (ii)  attempt by the Borrower to revoke (expressly, by later
     inconsistent notices or otherwise) in whole or in part any notice stated
     herein to be irrevocable (a Bank having in its sole discretion the options
     (A) to give effect to such attempted revocation and obtain indemnity under
     this Section 2.11(b) or (B) to treat such attempted revocation as having no
     force or effect, as if never made), or

            (iii) default by the Borrower in the performance or observance of
     any covenant or condition contained in this Agreement or any Related
     Document, including any failure of the Borrower to pay when due (by
     acceleration or otherwise) any principal, interest, fee or any other amount
     due hereunder or under any Related Document.

If the Bank sustains or incurs any such loss or expense, it may from time to
time notify the Borrower of the amount determined in good faith by such Bank
(which determination shall be conclusive) to be necessary to indemnify such Bank
for such loss or expense (each Bank being deemed for this purpose to have made,
maintained or funded each Euro-Rate Portion from a Corresponding Source of
Funds).  Such amount shall be due and payable by the Borrower to such Bank ten
(10) Business Days after such notice is given (and any Bank giving any such
notice shall notify the Administrative Agent of the amount so demanded).  If
requested by the Borrower, such Bank shall deliver to the Borrower a
certificate, which certificate shall be conclusive absent manifest error, as to
the amount due and payable under this Section 2.11(b) from time to time and the
method of calculating such amount.

         2.12. Taxes.
               ----- 

         (a)  Payments Net of Taxes.  All payments made by the Borrower under
              ---------------------                                          
this Agreement or any Related Document shall be made free and clear of, and
without reduction or withholding for or on account of, any present or future
income, stamp, documentary, excise or other taxes, levies, imposts, duties,
charges, fee, deductions or withholdings, now or hereafter imposed, levied,
collected, withheld or assessed by any Official Body, and all liabilities with
respect thereto, excluding;
<PAGE>
 
                                      -53-

            (i)   in the case of each Bank Party, income or franchise taxes
     imposed on such Bank Party by the jurisdiction under the laws of which such
     Bank Party is organized or any political subdivision or taxing authority
     thereof or therein or as a result of a connection between such Bank Party
     and any jurisdiction other than a connection resulting solely from this
     Agreement and the transactions contemplated hereby,

            (ii)  in the case of each Bank Party, income or franchise taxes
     imposed by any jurisdiction in which such Bank Party's lending offices
     which make or book Loans or issue Letters of Credit are located or any
     political subdivision or taxing authority thereof or therein, and

            (iii) any taxes payable solely as a result of the failure of a Bank
     described in Section 10.12(g) to timely deliver the forms described therein
     to the extent required thereby, other than if such failure is due to a
     change in law occurring after the date on which a form originally was
     required to be provided or if no such form is required

(all such non-excluded taxes, levies, imposts, deductions, charges or
withholdings being hereinafter called "Taxes").  If any Taxes are required to be
withheld or deducted from any amounts payable to any Bank Party under this
Agreement or any Related Document, the Borrower shall pay the relevant amount of
such Taxes and the amounts so payable to such Bank Party shall be increased to
the extent necessary to yield to such Bank Party (after payment of all Taxes)
interest or any such other amounts payable hereunder at the rates or in the
amounts specified in this Agreement and the Related Documents.  Whenever any
Taxes are paid by the Borrower with respect to payments made in connection with
this Agreement or any Related Document, as promptly as possible thereafter, the
Borrower shall send to the Administrative Agent for its own account or for the
account of such other Bank Party, as the case may be, a certified copy of an
original official receipt received by the Borrower showing payment thereof.

         (b)  Indemnity.  The Borrower hereby indemnifies each Bank Party for
              ---------                                                      
the full amount of all Taxes attributable to or arising from payments by or on
behalf of the Borrower to such Bank Party hereunder or under any of the Related
Documents, any Taxes paid by such Bank Party, and any present or future claims,
liabilities or losses with respect to or resulting from any omission to pay or
delay in paying any Taxes (including any incremental Taxes, interest or
penalties which may become payable by such Bank Party as a result of any failure
to pay such Taxes).  Such indemnification shall be made within five (5) Business
Days from the date such Bank Party makes written demand therefor.

         2.13. Funding by Branch, Subsidiary or Affiliate.
               ------------------------------------------ 
<PAGE>
 
                                      -54-

         (a)  Notional Funding.  Each Bank shall have the right from time to
              ----------------                                              
time, prospectively or retrospectively, without notice to the Borrower, to deem
any branch, subsidiary or affiliate of such Bank to have made, maintained or
funded any part of the Euro-Rate Portion at any time; provided, however, that
such Bank shall not have such right if such transfer would cause an event or
condition described in Section 2.06(f)(ii) or increase compensation payable by
the Borrower under Section 2.11(a). Any branch, subsidiary or affiliate so
deemed shall be known as a "Notional Euro-Rate Funding Office." Such Bank shall
deem any part of the Euro-Rate Portion or the funding therefor to have been
transferred to a different Notional Euro-Rate Funding Office if such transfer
would avoid or cure an event or condition described in Section 2.06(f)(ii) or
would lessen compensation payable by the Borrower under Section 2.11(a), and if
such Bank determines in its sole discretion that such transfer would be
practicable and would not have a material adverse effect on the affected part of
the Euro-Rate Portion, such Bank or any Notional Euro-Rate Funding Office (it
being assumed for purposes of such determination that each part of the Euro-Rate
Portion is actually made or maintained by or funded through the corresponding
Notional Euro-Rate Funding Office). Notional Euro-Rate Funding Offices may be
selected by such Bank without regard to such Bank's actual methods of making,
maintaining or funding the Euro-Rate Portion or any sources of funding actually
used by or available to such Bank.

         (b)  Actual Funding.  Each Bank shall have the right from time to time
              --------------                                                   
to make or maintain any part of the Euro-Rate Portion by arranging for a branch,
subsidiary or affiliate of such Bank to make or maintain such part of the Euro-
Rate Portion; provided, however, that such Bank shall not have such right if
such transfer would cause an event or condition described in Section 2.06(f)(ii)
or increase compensation payable by the Borrower under Section 2.11(a).  Such
Bank shall have the right to (i) hold any applicable Note payable to its order
for the benefit and account of such branch, subsidiary or affiliate or (ii)
request the Borrower to issue one or more promissory notes in the principal
amount of such part of the Euro-Rate Portion in substantially the form of
Exhibit A-1, Exhibit A-2, Exhibit A-3 or Exhibit B, as the case may be, with the
blanks appropriately filled, payable to such branch, subsidiary or affiliate and
with appropriate changes reflecting that the holder thereof is not obligated to
make any additional Loans to the Borrower.  The Borrower agrees to comply
promptly with any request under subsection (ii) of this Section 2.13(b).  If any
Bank causes a branch, subsidiary or affiliate to make or maintain any part of
the Euro-Rate Portion hereunder, all terms and conditions of this Agreement
shall, except where the context clearly requires otherwise, be applicable to
such part of the Euro-Rate Portion and to any Note payable to the order of such
branch, subsidiary or affiliate to the same extent as if such part of the Euro-
Rate Portion were made or maintained and such note were a Note payable to such
Bank's order.

         2.14. Currency Exchange Fluctuations.
               ------------------------------ 
<PAGE>
 
                                      -55-

         (a)  The Borrower will implement and maintain internal controls, and
shall cause KAP to implement and maintain internal controls, to monitor the
borrowings and repayments of Loans by the Borrower and borrowings and interest
reserves under the Australian Credit Facilities by KAP and the issuance of and
drawings under Letters of Credit, with the object of preventing any request for
the making of a Loan or the issuance of a Letter of Credit that would result in
the aggregate Revolving Credit Exposure of the Banks being in excess of the
aggregate Revolving Credit Commitments then in effect and of promptly
identifying and remedying any circumstance where, by reason of changes in
exchange rates, the aggregate Revolving Credit Exposure of the Banks exceeds the
aggregate Revolving Credit Commitments then in effect.

         (b)  If on any Computation Date the Administrative Agent shall have
determined that the U.S. Dollar Equivalent of the aggregate Revolving Credit
Exposure of the Banks exceeds the aggregate Revolving Credit Commitments due to
a change in currency exchange rates between the U.S. Dollar and the Australian
Dollar, then the Administrative Agent shall give notice to the Borrower that a
prepayment in the amount of such excess (or, if no Revolving Credit Loans are
outstanding, that the provision of cash collateral for outstanding Letters of
Credit in the amount of such excess) is required under Section 2.05(c)(ii)
within 5 Business Days unless, during such period, whether by currency
fluctuation or otherwise, such excess shall have been eliminated in its
entirety.

                                  ARTICLE III.

                               THE SUBFACILITIES
                               -----------------

         3.01. Letters of Credit.
               ----------------- 

         (a)  Generally.  Subject to the terms and conditions of this Agreement,
              ---------                                                         
and relying upon the representations and warranties herein set forth and upon
the agreements of the Banks set forth in Sections 3.04 and 3.05, the Standby and
Trade LC Issuing Bank agrees to issue for the account of the Borrower standby
letters of credit and documentary or import (trade) letters of credit as
provided in this Article III (each such letter of credit, as amended, modified
or supplemented from time to time, a "Standby or Trade Letter of Credit" and
collectively the "Standby or Trade Letters of Credit"); provided that, on the
date of the issuance of any Standby or Trade Letter of Credit, and after giving
effect to such issuance, the aggregate Revolving Credit Exposure shall not
exceed the aggregate Revolving Credit Commitments at such time; and provided,
further, that the aggregate Letter of Credit Exposure at any time outstanding
shall not exceed $20,000,000 plus the U.S. Dollar Equivalent of the Letter of
Credit Exposure of the Australian Term Loan Letter of Credit and the Australian
Revolving Loan Letter of Credit.  Each Standby or Trade Letter of Credit
<PAGE>
 
                                      -56-

shall (a) be for a purpose which is in the ordinary course of the Borrower's
business; (b) be in favor of such beneficiary or beneficiaries as the Borrower
shall specify and as shall be approved by the Standby or Trade LC Issuing Bank
in its reasonable discretion; (c) be denominated in Dollars; and (d) have an
expiration date no later than, (x) in the case of standby letters of credit, two
years after its date of issuance, and (y) in the case of documentary or import
(trade) letters of credit, 180 days after its date of issuance, provided that no
Standby or Trade Letter of Credit shall have an expiration date which is later
than five days prior to the Revolving Credit Expiration Date; provided, further,
that, on the fifth day prior to the Revolving Credit Expiration Date, the
Borrower shall provide for the termination and cancellation, in a manner
satisfactory to the Banks, of each then outstanding Standby or Trade Letter of
Credit.

            (b)  Australian Letters of Credit.
                 ---------------------------- 

            (i) Australian Term Loan Letter of Credit.  On the Closing Date the
                -------------------------------------                          
     Australian LC Issuing Bank will issue to the Australian Term Loan Facing
     Bank for the account of the Borrower an A$ denominated letter of credit
     with an initial Letter of Credit Undrawn Availability equal to the
     Australian Dollar Equivalent of $40,000,000, substantially in the Form of
     Exhibit I-1 hereto (the "Australian Term Loan Letter of Credit").  The
     Australian Term Loan Letter of Credit shall expressly provide that such
     Letter of Credit may only be drawn upon (x) in the event of a default in

     Amount of each Bank shall be Pro Rata automatically and permanently
     reduced, by the U.S. Dollar Equivalent of each A$ denominated amount
     received by the Australian Term Loan Facing Bank in respect of any
     repayment, prepayment or Scheduled Amortization Payment applied to

     Letter of Credit Undrawn Availability equal to the Australian Dollar
     Equivalent of $10,000,000 substantially in the Form of Exhibit I-2 hereto
     (the "Australian Revolving Loan Letter of Credit"). The Australian
     Revolving Loan Letter of Credit shall expressly provide that such Letter of
     Credit may only be drawn upon (x) in the event of a default in the payment
     of principal or interest under the Australian Revolving Loan Facility or
     (y) upon the occurrence of an event described in Section 8.01(p) or (q)
     with respect to KAP in the lesser of the amount of principal and interest
     then due to the Australian Revolving Loan Facing Bank or the Letter of
     Credit Undrawn Availability of the Australian Revolving Loan Letter of
     Credit. The stated amount with respect to, and the Letter of Credit Undrawn
     Availability of, the Australian Revolving Loan Letter of Credit may be
     permanently reduced by the Borrower as provided in the Australian Revolving
     Loan Facility, in which case the Revolving Credit Committed Amount of each
     Bank shall be Pro Rata automatically and permanently reduced by the U.S.
     Dollar Equivalent of the A$ denominated amount of such reduction. The
     Australian Revolving Loan Letter of Credit shall (a) be for the purpose of

              -------------------------------

respective Issuing Bank, for the sole account of such Issuing Bank, such other
issuance, administration, maintenance, amendment, drawing and negotiation fees
as may be customarily charged by such Issuing Bank from time to time in
connection with letters of credit issued by it.

         3.03. Procedure for Issuance and Amendment of
               Letters of Credit.
               ------------------------------------------

         (a)  Procedure for Issuance.  The Borrower may from time to time
              ----------------------                                     
request the Standby and Trade LC Issuing Bank to issue a Standby or Trade Letter
of Credit by delivering to the Standby and Trade LC Issuing Bank at such
location as the Standby and Trade LC Issuing Bank may from time to time
designate, with a copy to the Administrative Agent, at least three (3) Business
Days prior to the proposed Standby or Trade Letter of
<PAGE>
 
                                      -59-

Credit issuance date (or on such shorter notice as the Standby and Trade LC
Issuing Bank may approve in its discretion), an application, in such form as may
from time to time be approved by the Standby and Trade LC Issuing Bank (the
"Letter of Credit Application"), completed to the satisfaction of the Standby
and Trade LC Issuing Bank, together with such other certificates, documents and
other papers and information as the Standby and Trade LC Issuing Bank may
reasonably request. Upon receipt of any Letter of Credit Application, the
Standby and Trade LC Issuing Bank will process such Letter of Credit
Application, and the other certificates, documents and other papers and
information delivered to it in connection therewith, in accordance with its
customary procedures and, unless it has been notified by the Administrative
Agent by the Standby and Trade LC Issuing Bank's close of business on the
Business Day preceding the proposed Standby or Trade Letter of Credit issuance
date that any condition thereto has not been satisfied, issue such Standby or
Trade Letter of Credit by delivering the original thereof to the beneficiary and
furnishing a copy thereof to the Borrower and the Administrative Agent (and the
Administrative Agent shall upon request promptly furnish copies thereof to the
Banks).

         (b)  Extension and Increase.  (i)  The Borrower may from time to time
              ----------------------                                          
request the Standby and Trade LC Issuing Bank to extend the expiration date of
an outstanding Standby or Trade Letter of Credit or increase the Letter of
Credit Undrawn Availability thereunder.  Such extension or increase shall for
all purposes hereof (including Section 5.02) be treated as though the Borrower
had requested issuance of a new Standby or Trade Letter of Credit pursuant to
Section 3.03(a); provided that the Standby or Trade LC Issuing Bank may, if it
so elects, issue an amendment to the particular Standby or Trade Letter of
Credit in question providing for such extension or increase in lieu of issuing a
new Standby or Trade Letter of Credit in substitution for the outstanding
Standby or Trade Letter of Credit.

         (ii) The Borrower may request the Australian LC Issuing Bank to
increase the Letter of Credit Undrawn Availability of the Australian Revolving
Loan Letter of Credit by the Australian Dollar Equivalent of $10,000,000 on the
date of any such increase.  Such increase shall for all purposes hereof
(including Section 5.02) be treated as though the Borrower had requested the
issuance of a new Letter of Credit. The Australian LC Issuing Bank may, if it so
elects, issue an amendment to the Australian Revolving Loan Letter of Credit
providing for such increase in lieu of issuing a new Australian Revolving Loan
Letter of Credit in substitution for the outstanding Australian Revolving Loan
Letter of Credit.

         At least three (3) Business Days prior to the date upon which the
Borrower shall desire to increase the Letter of Credit Undrawn Availability of
the Australian Revolving Loan Letter of Credit, the Borrower shall deliver to
the Australian LC Issuing Bank at such location as the Australian LC Issuing
Bank may from time to time designate, with a copy to the Administrative Agent,
an application, in such form as may from time to time be approved by the
Australian LC Issuing Bank, completed to the satisfaction of the Australian
<PAGE>
 
                                      -60-

LC Issuing Bank, together with such other certificates, documents and other
papers and information as the Australian LC Issuing Bank may reasonably request.
Upon receipt of the aforementioned application, the Australian LC Issuing Bank
will process such application, and the other certificates, documents and other
papers and information delivered to it in connection therewith, in accordance
with its customary procedures and, unless it has been notified by the
Administrative Agent by the Australian LC Issuing Bank's close of business on
the Business Day preceding the proposed increase in the Letter of Credit Undrawn
Availability of the Australian Revolving Loan Letter of Credit that any
condition thereto has not been satisfied, increase the Letter of Credit Undrawn
Availability of the Australian Revolving Loan Letter of Credit consistent with
the Borrower's request by either issuing an amendment to the Australian
Revolving Loan Letter of Credit providing for such increase or by issuing a new
Australian Revolving Loan Letter of Credit in substitution for the outstanding
Australian Revolving Loan Letter of Credit, delivering the original amendment or
new Australian Revolving Loan Letter of Credit, as the case may be, to the
beneficiary and furnishing a copy thereof to the Borrower and the Administrative
Agent (and the Administrative Agent shall upon request promptly furnish copies
thereof to the Banks).

         (c)  Limitations on Issuance and Extension.  (i)  As between the
              -------------------------------------                      
Borrower and the Standby and Trade LC Issuing Bank, the issuance or extension of
any Standby or Trade Letter of Credit (including any deemed issuance pursuant to
Section 3.10 or arising from any increase or extension of any outstanding
Standby or Trade Letter of Credit pursuant to Section 3.03(b)) is within the
reasonable discretion of the Standby and Trade LC Issuing Bank.

         (ii)  As between the Standby and Trade LC Issuing Bank and the other
Bank Parties, the Standby and Trade LC Issuing Bank shall be justified and fully
protected in issuing any Standby or Trade Letter of Credit (including any deemed
issuance pursuant to Section 3.10 or arising from any increase or extension of
any outstanding Standby or Trade Letter of Credit pursuant to Section 3.03(b))
absent notice from the Administrative Agent as provided in Section 3.03(a), in
each case notwithstanding any subsequent notices to the Standby and Trade LC
Issuing Bank, any knowledge of an Event of Default or Potential Default, any
knowledge of failure of any condition specified in Section 5.02 to be satisfied,
any other knowledge of the Standby and Trade LC Issuing Bank, or any other
event, condition or circumstance whatsoever.

         (iii) As between the Administrative Agent and the Banks, the
Administrative Agent shall have no obligation to direct the Standby and Trade LC
Issuing Bank pursuant to Section 3.03(a) not to issue any Standby or Trade
Letter of Credit unless the Administrative Agent shall have received from the
Required Banks, at least two (2) Business Days before the date of such proposed
issuance, an unrevoked written notice that any condition precedent set forth in
Section 5.02 will not be satisfied on such date and expressly requesting that
the
<PAGE>
 
                                      -61-

Administrative Agent direct the Standby and Trade LC Issuing Bank not to issue
such Standby or Trade Letter of Credit. Unless the Administrative Agent has
received such notice, the Administrative Agent shall be justified and fully
protected, as against the Banks, in failing to direct the Standby and Trade LC
Issuing Bank not to issue such Standby or Trade Letter of Credit,
notwithstanding any subsequent notices to the Administrative Agent, any
knowledge of an Event of Default or Potential Default, any knowledge of failure
of any condition specified in Section 5.02 to be satisfied, any other knowledge
of the Administrative Agent, or any other event, condition or circumstance
whatsoever.

         (d)  Amendments.  At the request of the Borrower from time to time, and
              ----------                                                        
subject to satisfaction of such conditions as an Issuing Bank may require, such
Issuing Bank may amend, modify or supplement Letters of Credit, or waive
compliance with any condition of issuance or payment, without the consent of,
and without liability to, the Administrative Agent or any Bank; provided that,
notwithstanding the foregoing, an Issuing Bank shall not issue any Letter of
Credit as to which it has received a notice from the Administrative Agent as
contemplated by Section 3.03(a); and provided, further, that any amendment,
modification or supplement that extends the expiration date or increases the
amount available to be drawn under any outstanding Standby or Trade Letter of
Credit shall be subject to Section 3.03(b).

         3.04. Letter of Credit Participating Interests.
               ---------------------------------------- 

         In the case of each Letter of Credit, effective as of the date of the
issuance thereof (including any deemed issuance pursuant to Section 3.10 or
arising from any increase or extension of any outstanding Letter of Credit
pursuant to Section 3.03(b)), each Issuing Bank automatically shall be deemed,
irrevocably and unconditionally, to have sold, assigned, transferred and
conveyed to each Bank, and each Bank automatically shall be deemed, irrevocably
and unconditionally, to have purchased, acquired, accepted and assumed from each
Issuing Bank, without recourse to, or representation or warranty by, any such
Issuing Bank, an undivided interest in a proportion equal to such Bank's
Revolving Credit Proportion, in all of such Issuing Bank's rights and
obligations in, to or under such Letter of Credit, the related Letter of Credit
Reimbursement Obligations and all collateral, guarantees and other rights from
time to time directly or indirectly securing the foregoing (such interest of
each Bank being referred to herein as a "Letter of Credit Participating
Interest").  Other than Letter of Credit Reimbursement Obligations and Letter of
Credit commissions, amounts payable pursuant to Section 3.02(a) from time to
time under or in connection with a Letter of Credit shall be for the sole
account of the Issuing Bank issuing such Letter of Credit.  On the date that any
Purchasing Bank becomes a party to this Agreement in accordance with Section
10.12, Letter of Credit Participating Interests in any outstanding Letters of
Credit held by the Bank from which such Purchasing Bank acquired its interest
hereunder shall be proportionately reallotted between such Purchasing Bank and
such transferor Bank (and, to the extent such transferor Bank is the Issuing
Bank, the Purchasing Bank shall be deemed to
<PAGE>
 
                                      -62-

have acquired a Letter of Credit Participating Interest from such transferor
Bank to such extent). Except as contemplated by the immediately preceding
sentence, neither the Letter of Credit Participating Interest of any Bank
hereunder nor its obligations under this Article III may be assigned or
transferred without the written consent of the Issuing Bank of the underlying
Letter or Letters of Credit. Each Bank hereby expressly and unconditionally
agrees that its obligation to participate in each Letter of Credit issued
hereunder and its obligation to make the payments specified in Section 3.05
shall be absolute, irrevocable and unconditional, and shall not be affected by
any event, condition or circumstance whatsoever. The failure of any Bank to make
any such payment shall not relieve any Bank of its funding obligation hereunder
on the date due, but no Bank shall be responsible for the failure of any other
Bank to meet its funding obligations hereunder.

         3.05. Payments.
               -------- 

         (a)  Reimbursement of Issuing Banks.  The Borrower agrees (i) to
              ------------------------------                             
reimburse each Issuing Bank, forthwith upon its demand, by making payment to the
Administrative Agent for the account of such Issuing Bank in accordance with
Section 2.10, on the date and in the amount of each payment made by such Issuing
Bank under any Letter of Credit, without notice, protest or demand, all of which
are expressly waived, and a cause of action therefor shall immediately accrue,
and (ii) to pay to the Administrative Agent for the account of such Issuing Bank
interest on any Letter of Credit Unreimbursed Draw for each day from the date of
such payment until demand at a fluctuating rate per annum equal to the then
current Base Rate Option applicable to Revolving Credit Loans and from the date
of demand until reimbursement in full thereof (before and after judgment) at a
fluctuating rate per annum equal to 2% above the then current Base Rate Option
applicable to Revolving Credit Loans, in each case such interest to change
automatically from time to time effective as of the effective date of each
change in the Base Rate.

         (b)  Agreement of Banks.  In the event that an Issuing Bank makes a
              ------------------                                            
payment under any Letter of Credit and is not reimbursed in full therefor
forthwith upon demand of such Issuing Bank (or if any reimbursed amount is
required to be returned by such Issuing Bank), such Issuing Bank shall promptly
notify the Administrative Agent thereof (which notice may be by telephone), and
the Administrative Agent shall forthwith notify each Bank (which notice may be
by telephone promptly confirmed in writing) thereof.  No later than the
Administrative Agent's close of business at its Office on the date such notice
is given, each such Bank will pay to the Administrative Agent, for the account
of such Issuing Bank, in immediately available funds, an amount equal to such
Bank's Pro Rata share of the respective Letter of Credit Unreimbursed Draw.  If
and to the extent that any Bank fails to make such payment to the Administrative
Agent for the account of such Issuing Bank on such date, such Bank shall pay
such amount, on demand, together with interest, for such Issuing Bank's account,
for each day from and including the date of such Issuing Bank's payment to
<PAGE>
 
                                      -63-

and including the date of payment to such Issuing Bank (before and after
judgment) at the following rates per annum: (i) for each day from and including
the date of such payment by such Issuing Bank to and including the second
Business Day thereafter, at the Federal Funds Effective Rate for such day, and
(ii) for each day thereafter, at the rate applicable to Letter of Credit
Unreimbursed Draws under Section 3.05(a) for such day.

         (c)  Receipt of Payment.  Whenever, at any time, after an Issuing Bank
              ------------------                                               
has made payment under a Letter of Credit and has received from any Bank such
Bank's Pro Rata share of the Letter of Credit Unreimbursed Draw with respect
thereto, such Issuing Bank receives any payment or makes any application of
funds on account of such Letter of Credit Unreimbursed Draw, such Issuing Bank
will pay to the Administrative Agent, for the account of such Bank, such Bank's
Pro Rata share of such payment or application.

         (d)  Rescission.  If any amount received by an Issuing Bank on account
              ----------                                                       
of any Letter of Credit Reimbursement Obligation shall be avoided, rescinded or
otherwise returned or paid over by such Issuing Bank for any reason at any time,
whether before or after the termination of this Agreement (or such Issuing Bank
believes in good faith that such avoidance, rescission, return or payment is
required, whether or not such matter has been adjudicated), each Bank will,
promptly upon notice from the Administrative Agent or such Issuing Bank, pay
over to the Administrative Agent, for the account of such Issuing Bank, such
Bank's Pro Rata share of such amount (to the extent such amount was therefore
paid to such Bank hereunder), together with its Pro Rata share of any interest
or penalties payable with respect thereto.

         (e)  Equalization.  If any Bank receives any payment or makes any
              ------------                                                
application on account of its Letter of Credit Participating Interest in a
Letter of Credit, such Bank shall forthwith pay over to the Issuing Bank of such
Letter of Credit in Dollars and in like kind of funds received or applied by it
the amount in excess of such Bank's ratable share of the amount so received or
applied.

         3.06. Further Assurances.
               ------------------ 

         The Borrower hereby agrees from time to time to do and perform any and
all acts and to execute any and all other or further instruments reasonably
requested by each Issuing Bank more fully to effect the purposes of this
Agreement and the issuance of the Letters of Credit hereunder.

         3.07. Obligations Absolute.

<PAGE>
 
                                      -64-

         The payment obligations of the Borrower under Section 3.05 shall be
unconditional and irrevocable and shall be paid strictly in accordance with the
terms of this Agreement under all circumstances, including the following
circumstances:

         (a)  any lack of validity or enforceability of this Agreement, any
     Letter of Credit, any other Related Document or any other documents,
     instruments or agreements evidencing or otherwise relating to any
     obligation of the Borrower secured or supported by any Letter of Credit;

         (b)  the existence of any claim, set-off, defense or other right which
     the Borrower or any other person may have at any time against any
     beneficiary or any transferee of any Letter of Credit (or any persons for
     whom any such beneficiary or any such transferee may be acting), the
     Issuing Bank of such Letter of Credit or any other Bank Party, or any other
     person, whether in connection with this Agreement, the transactions
     contemplated hereby or any unrelated transaction;

         (c)  any draft, certificate, statement or other document presented
     under any Letter of Credit proving to be forged, fraudulent, invalid or
     insufficient in any respect, or any statement therein being untrue or
     inaccurate in any respect;

         (d)  payment by an Issuing Bank under any Letter of Credit issued by
     such Issuing Bank against presentation of a draft or certificate which does
     not comply with the terms of such Letter of Credit, or payment by an
     Issuing Bank under any Letter of Credit issued by such Issuing Bank in any
     other circumstances in which any condition to payment is not met, except
     payment resulting solely from the gross negligence or willful misconduct of
     any such Issuing Bank, as finally determined by a court of competent
     jurisdiction; or

         (e)  any other event, condition, circumstance or happening whatsoever,
     whether or not similar to any of the foregoing.

         3.08. Certain Provisions Relating to the Issuing Banks;
               Additional Provisions Regarding Letters of Credit.

liable for any action taken or omitted to be taken by it under or in connection

and holds each Issuing Bank harmless from and against any and all claims,
damages, losses, liabilities, costs, expenses, actions, judgments and suits of
any kind or nature whatsoever (including reasonable attorneys' fees and
expenses) (collectively "Claims") that may at any time be imposed on, incurred
by or asserted against such Issuing Bank in its capacity as such as a result of,
or arising out of, or in any way relating to or by reason of or in connection
with this Agreement or any Related Document, any transaction contemplated hereby
or thereby, or any transaction secured or financed, in whole or in part,
directly or indirectly, with any Letter of Credit or the proceeds thereof,
except to the extent, but only to the extent, any such Claims are caused by such
Issuing Bank's gross negligence or willful misconduct, as finally determined by
a court of competent jurisdiction.  Each Bank agrees to reimburse and indemnify
each Issuing Bank for and against any and all Claims required to be reimbursed
by the Borrower pursuant to the immediately preceding sentence but not so

         3.09. Cash Collateral for Letters of Credit.
               ------------------------------------- 

         (a)  Letter of Credit Collateral Account.  If required, the Collateral
              -----------------------------------                              
Agent shall maintain in its own name at its Office a deposit account (the
"Letter of Credit Collateral Account"), which shall bear interest (added to the
deposit balance) in accordance with the Collateral Agent's ordinary practices
for deposit accounts of like size and nature, over which the Collateral Agent
shall have sole dominion and control, and the Borrower shall have no right to
withdraw any funds deposited therein.  The Collateral Agent shall deposit into
the Letter of Credit Collateral Account such funds as this Agreement or any
Related Document requires to be paid therein.  As security for the payment of
all Obligations, the Borrower hereby grants, conveys, assigns, pledges,
transfers to the Collateral Agent, and creates in the Collateral Agent's favor,
a continuing Lien on and security interest in, the Letter of Credit Collateral
Account, all amounts from time to time on deposit therein, all proceeds of the
conversion, voluntary or involuntary, thereof into cash, instruments, securities
or other property, and all other proceeds thereof.  The Borrower hereby
represents, warrants, covenants and agrees that such Lien shall at all times be
valid and perfected, prior to all other Liens, and the Borrower shall take or
cause to be taken all such actions and execute and deliver all such instruments
and documents as may be necessary or, in the Collateral Agent's reasonable
judgment, desirable to perfect or protect such Lien.  The Borrower shall not
create or suffer to exist any Lien on any amount or investment held in the
Letter of Credit Collateral Account other than the Lien in favor of the
Collateral Agent granted under this Section.

         (b)  Cash Collateral for Letter of Credit Exposure in Certain
              --------------------------------------------------------
Circumstances.  To the extent that this Agreement or any Related Document
- -------------                                                            
requires a payment, prepayment or other application of funds to be made with
respect to the Revolving Credit Loans or Swingline Loans, such provision shall
be construed as follows:  after payment in full by the Borrower of the
outstanding Swingline Loans, the outstanding Revolving Credit Loans, and the
outstanding Letter of Credit Unreimbursed Draws, then, to the extent of the
excess, if any, of the aggregate Letter of Credit Exposure at such time over the
balance in the Letter of Credit Collateral Account, an amount equal to
the remainder of the amount so required to be paid by the Borrower shall
immediately be paid by the Borrower to the Collateral Agent for deposit in the
Letter of Credit Collateral Account. In addition, the Borrower agrees that,
without limitation of the foregoing or of any other provisions of this Agreement
or the Related Documents requiring collateral for the Letters of Credit or other
Obligations in whole or in part, and without limitation of other rights or
remedies under this Agreement or the Related Documents or at law or in equity,
if all the Revolving Credit Loans become due and payable pursuant to Section
8.02 hereof, the Borrower shall immediately pay to the Collateral Agent, for
deposit in the Letter of Credit Collateral Account, an amount equal to
<PAGE>
 
                                      -67-

the excess, if any, of the aggregate Letter of Credit Exposure at such time over
the balance in the Letter of Credit Collateral Account.

         (c)  Application of Funds.  The Collateral Agent shall apply funds in
              --------------------                                            
the Letter of Credit Collateral Account:  (i) on account of Letter of Credit
Reimbursement Obligations as and when the same become due and payable if and to
the extent that the Borrower fails directly to pay the same, and (ii) if no
Letter of Credit Reimbursement Obligations are due and payable, no Letters of
Credit are outstanding and the balance of the Letter of Credit Collateral
Account exceeds the aggregate Letter of Credit Exposure, the excess shall be
applied on account of the other Obligations.  If all Obligations (other than
Obligations constituting contingent obligations under indemnification provisions
which survive indefinitely, so long as no unsatisfied claim has been made under
any such indemnification provision) have been indefeasibly paid in full in cash,
all Commitments have terminated and all Letters of Credit have expired, promptly
following demand by the Borrower, the Collateral Agent shall release to the
Borrower all remaining funds in the Letter of Credit Collateral Account.

         (d)  Survival of Provisions.  The provisions of this Section 3.09 shall
              ----------------------                                            
continue in full force and effect from and after the date hereof until the
obligation of each Issuing Bank to issue Letters of Credit has expired or has
been terminated, all Letters of Credit have expired or have been terminated and
all Letter of Credit Reimbursement Obligations have been indefeasibly paid in
full in cash.

         3.10. Certain Letters of Credit Outstanding as of Closing Date.
               -------------------------------------------------------- 

         Notwithstanding anything to the contrary set forth herein, the Borrower
shall be deemed to have requested the Standby and Trade LC Issuing Bank to issue
on the Closing Date, and the Standby and Trade LC Issuing Bank shall be deemed
to have issued on such date, the letters of credit set forth on Schedule 3.10,
without further action on the part of the Borrower or the Standby and Trade LC
Issuing Bank (and, without limitation of the foregoing, the Borrower shall not
be required to pay any commission pursuant to Section 3.02(a) or any issuance
fee pursuant to Section 3.02(b) in connection with any such deemed issuance).
From and after such deemed issuance, all such letters of credit shall be deemed
to be Standby or Trade Letters of Credit issued and outstanding hereunder for
all purposes hereof.

Swingline Bank shall not make any Swingline Loan to the extent that the
aggregate amount of Swingline Loans outstanding would exceed the Swingline
Current Availability most recently notified to it, as more fully provided in
Section 3.12(a) hereof.

         (b)  Nature of Credit.  Within the limits of time and amount set forth
              ----------------

amount equal to the Swingline Subfacility Amount.

         (d)  Maturity.  To the extent not due and payable earlier, the
              --------

         3.12. Limitations on the Making of Swingline Loans.
               -------------------------------------------- 

         (a)  Swingline Current Availability.  The Administrative Agent shall
              ------------------------------                                 
calculate the Swingline Current Availability each time there is a change in the
aggregate outstanding principal amount of the Revolving Credit Loans, the
aggregate Letter of Credit Exposure or the Revolving Credit Committed Amounts.
The "Swingline Current Availability" at any time shall be equal to the lesser of

            (i) the Swingline Subfacility Amount, or

            (ii) the amount equal to (A) the sum of the Revolving Credit
     Committed Amounts of the Banks at such time, minus (B) the sum of the
     aggregate principal amount of Revolving Credit Loans and the aggregate
     Letter of Credit Exposure at such time.

Each time the Swingline Current Availability changes, the Administrative Agent
shall promptly notify the Swingline Bank (by telephone promptly confirmed in
writing) of such fact, stating the new Swingline Current Availability.  From and
after the second Business Day after receiving such notice from the
Administrative Agent, the Swingline Bank shall not make any Swingline Loan to
the extent that the aggregate principal amount of Swingline Loans would exceed
the Swingline Current Availability so notified to the Swingline Bank.

         (b)  Rights of the Parties.  As between the Borrower, on the one hand,
              ---------------------                                            
and the Swingline Bank and the other Bank Parties, on the other hand, the making
of any Swingline Loan is within the discretion of the Swingline Bank.  As
between the Swingline Bank, on the one hand, and the other Bank Parties, on the
other hand, the Swingline Bank shall not make any Swingline Loan outside the
limitations of time and amount set forth in Section 3.11 hereof, and shall not
make any Swingline Loan if the Swingline Bank shall have received, at least two
Business Days before making such Swingline Loan, from the Required Banks an
unrevoked written notice that any condition precedent set forth in Section 5.02
will not be satisfied and expressly requesting that the Swingline Bank cease to
make Swingline Loans.  Absent such notice, the Swingline Bank shall be justified
and fully protected, as against the Administrative Agent and the Banks, in
making Swingline Loans, notwithstanding any knowledge of an Event of Default or
Potential Default, any knowledge of failure of any condition specified in
Section 5.02 hereof to be satisfied, any other knowledge of the Swingline Bank,
or any other event, condition or circumstance whatever.

         3.13.  Swingline Loan Participating Interests.
                -------------------------------------- 

         (a)  Generally.  At the discretion of the Swingline Bank at any time,
              ---------                                                       
on one Business Day's notice to each Bank, the Swingline Bank may require each
other Bank to purchase, acquire, accept and assume from the Swingline Bank,
without recourse to, or representation or warranty by, the Swingline Bank, an
undivided interest, in a proportion equal to such Bank's Pro Rata share, in all
of the Swingline Bank's rights and obligations in, to or under the outstanding
Swingline Loans, together with accrued and unpaid interest thereon, and all
collateral, guarantees and other rights from time to time directly or indirectly
securing the foregoing (such interest of each Bank being referred to herein as a
"Swingline Loan Participating Interest").  On the date that any Purchasing Bank
becomes a party to this Agreement in accordance with Section 10.12 hereof,
Swingline Loan Participating Interests in any outstanding Swingline Loans held
by the Bank from which such Purchasing Bank acquired its interest hereunder
shall be proportionately reallotted between such Purchasing Bank and such
transferor Bank.

         (b)  Obligations Absolute.  Notwithstanding any other provision hereof,
              --------------------                                              
each Bank hereby agrees that its obligation to participate in each Swingline
Loan issued in accordance herewith, and its obligation to make the payments
specified in Section 3.05 hereof, are each absolute, irrevocable and
unconditional and shall not be affected by any event, condition or circumstance
whatever.  The failure of any Bank to make any such payment shall not relieve
any other Bank of its funding obligation hereunder on the date due, but no Bank
shall be responsible for the failure of any other Bank to meet its funding
obligations hereunder.

         (c)  Payment by Banks on Account of Swingline Loans.  If the Swingline
              ----------------------------------------------                   
Bank desires to sell Swingline Loan Participants Interests to the Banks, the
Swingline Bank will promptly notify the Administrative Agent thereof (which
notice may be by telephone), and the Administrative Agent shall forthwith notify
each Bank (which notice may be by telephone promptly confirmed in writing)
thereof.  No later than the Administrative Agent's close of business on the date
such notice is given by the Administrative Agent, each such Bank will pay to the
Administrative Agent, for the account of the Swingline Bank, in immediately
available funds, an amount equal to such Bank's Pro Rata share of the
outstanding principal amount of the Swingline Loans and accrued and unpaid
interest thereon.  If and to the extent that any Bank fails to make such payment
to the Swingline Bank on such date, such Bank shall pay such amount on demand,
together with interest, for the Swingline Bank's own account, for each day from
and including the date of the Swingline Bank's payment to and including the date
of repayment to the Swingline Bank (before and after judgment) at the following
rates per annum:  (x) for each day from and including the date of such payment
by the Swingline Bank to and including the second Business Day thereafter, at
the Federal
<PAGE>
 
                                      -71-

Funds Effective Rate for such day, and (y) for each day thereafter, at the rate
applicable to the Swingline Loans for such day.

         (d)  Distributions to Participants.  If, at any time, after the
              -----------------------------                             
Swingline Bank has made a Swingline Loan and has received from any Bank such
Bank's share of such Swingline Loan, and the Swingline Bank receives any payment
or makes any application of funds on account of such Swingline Loan, the
Swingline Bank will pay to the Administrative Agent, for the account of such
Bank, such Bank's Pro Rata share of such payment.

         (e)  Rescission.  If any amount received by the Swingline Bank on
              ----------                                                  
account of any Swingline Loan or interest thereon shall be avoided, rescinded or
otherwise returned or paid over by the Swingline Bank for any reason at any
time, whether before or after the termination of this Agreement (or the
Swingline Bank believes in good faith that such avoidance, rescission, return or
payment is required, whether or not such matter has been adjudicated), each such
Bank will, promptly upon notice from the Administrative Agent or the Swingline
Bank, pay over to the Administrative Agent for the account of the Swingline Bank
its Pro Rata share of such amount, together with its Pro Rata share of any
interest or penalties payable with respect thereto.

         (f)  Equalization.  If any Bank receives any payment or makes any
              ------------                                                
application on account of its Swingline Loan Participating Interest, such Bank
shall forthwith pay over to the Swingline Bank in Dollars and in like kind of
funds received or applied by it the amount in excess of such Bank's ratable
share of the amount so received or applied.

         3.14. Certain Provisions Relating to the Swingline Bank.

or other communication is made in a manner permitted or required by this
Agreement or any Related Document) purportedly made by or on behalf of the
proper party or parties, and the Swingline Bank shall not have any duty to
verify the identity or authority of any person giving such notice or other
communication.  The Swingline Bank may consult with legal counsel (including 
in-house counsel for the Swingline Bank or in-house or other counsel, for the
Borrower), independent public accountants and any other experts selected by it
from time to time, and the Swingline Bank shall not be liable for any action
taken or omitted to be taken in good faith in accordance with the advice of such
counsel, accountants or experts.  Whenever the Swingline Bank shall deem it
necessary or desirable that a matter be proved or established with respect to
the Borrower or any Bank Party, such matter may be established by a certificate
of the Borrower or such other Bank Party, as the case may be, and the Swingline
Bank may conclusively rely upon such certificate.

         (c)  Indemnification of Swingline Bank.  The Borrower hereby
              ---------------------------------                      
indemnifies and holds the Swingline Bank harmless from and against any and all
claims, damages, losses, liabilities, expenses, actions, judgments and suits of
any kind or nature whatsoever (including reasonable attorneys' fees and

jurisdiction.  Each Bank agrees to reimburse and indemnify the Swingline Bank
for and against any and all Swingline Bank Claims required to be reimbursed by
the Borrower pursuant to the immediately preceding sentence but not so
reimbursed.

         4.05. Absence of Conflicts.
               -------------------- 

         Except as set forth on Schedule 4.05, neither the execution and

transactions herein or therein contemplated nor performance of or compliance
with the terms and conditions hereof or thereof will (a) violate or conflict

properties may be subject or bound, the consequences of which has,
<PAGE>
 
                                      -75-

or would reasonably be expected to have, a Material Adverse Effect, or to result
in any liability of any Bank Party, or (c) result in the creation or imposition
of any Lien upon any property of the Borrower, any of the Borrower's
Subsidiaries, KAP or any of KAP's Subsidiaries (other than the Unrestricted
Subsidiaries), except for any Lien created by or pursuant to the Security
Documents.

         4.06. Financial Statements.
               -------------------- 

         (a)  The Borrower has heretofore furnished or caused to be furnished to
the Banks audited financial statements of the Borrower and its Consolidated
Subsidiaries and of KAP and its Consolidated Subsidiaries (including the
Unrestricted Subsidiaries) for each of the three years in the period ended
December 31, 1996, and unaudited financial statements of the Borrower and its
Consolidated Subsidiaries and of KAP and its Consolidated Subsidiaries
(including the Unrestricted Subsidiaries) for the fiscal quarters ending March
31, 1997, June 30, 1997 and September 30, 1997, in each case including balance
sheets and the related statements of income.  The Borrower has also heretofore
furnished or caused to be furnished to the Banks unaudited interim combined
(where available, and where not, uncombined) consolidated and consolidating
financial statements of the Borrower and KAP for each fiscal month and quarterly
period ended subsequent to June 30, 1997 as to which such financial statements
are available.  Such financial statements present fairly the financial condition
of Borrower and its Consolidated Subsidiaries and KAP and its Consolidated
Subsidiaries (including the Unrestricted Subsidiaries) as of the end of such
periods and the results of its operations for such periods, all in conformity
with GAAP (or in the case of KAP and its Consolidated Subsidiaries (including
the Unrestricted Subsidiaries), in conformity with Australian generally accepted
accounting principals in effect at the date of this Agreement consistently
applied).  Except as disclosed in the financial statements referred to herein or
on Schedule 4.06, as of the date hereof, both before and after giving effect to
the Transaction, none of the Borrower, its Subsidiaries, KAP or its Subsidiaries
has any contingent liabilities (including liabilities for taxes), unusual
forward or long-term commitments or unrealized or anticipated losses from
unfavorable commitments which have, or would reasonably be expected to have, a
Material Adverse Effect.

         (b)  The Borrower has also furnished to the Banks a pro forma
consolidated balance sheet as of September 30, 1997 of the Borrower and its
Consolidated Subsidiaries (including KAP and its Consolidated Subsidiaries)
giving effect to the Transaction.  Such pro forma balance sheet presents fairly
the financial condition of the Borrower and its Consolidated Subsidiaries
(including KAP and its Consolidated Subsidiaries) on a pro forma basis and were
prepared in accordance with GAAP to the extent such principles can be applied on
a pro forma basis.
<PAGE>
 
                                      -76-

         (c)  The Borrower has also furnished to the Banks projected financial
statements for the Borrower and its Consolidated Subsidiaries (including KAP and
its Consolidated Subsidiaries) for each of the seven fiscal years following the
Closing Date, demonstrating the projected consolidated financial condition,
results of operations and cash flows of the Borrower and its Consolidated
Subsidiaries (including KAP and its Consolidated Subsidiaries) for such periods,
after giving effect to the Transaction. Such projections are accompanied by a
written statement of the assumptions and estimates underlying such projections.
Such projections, assumptions and estimates were made on a reasonable basis and
in good faith, and nothing has come to the attention of the Borrower which would
lead either to believe that such projections will not be attained or exceeded.

         4.07. No Event of Default; Compliance with Instruments.
               ------------------------------------------------ 

         No event has occurred and is continuing and no condition exists which

any of KAP's Subsidiaries is in violation of (a) its articles of incorporation
or bylaws (or other comparable constituent documents) or (b) any agreement or
instrument to which it is a party or by which it or any of its respective
properties may be subject or bound, the consequences of which has, or would
reasonably be expected to have, a Material Adverse Effect.

         4.08. Litigation.
               ---------- 

         Except as set forth in the financial statements referred to in Section
4.06 or as set forth on Schedule 4.08, there is no pending or (to the Borrower's
knowledge after due inquiry) threatened proceeding by or before any Official
Body against or affecting the Borrower, any of the Borrower's Subsidiaries, KAP
or any of KAP's Subsidiaries (a) seeking to challenge, prevent or declare
illegal any of the transactions contemplated by the Transaction, this Agreement
or the Related Documents, or (b) as to which there is a reasonable probability
of it being adversely decided and, if adversely decided, which would reasonably
be expected to have a Material Adverse Effect.

         4.09. Subsidiaries.
               ------------ 

         Schedule 4.09 sets forth, upon the consummation of the Transaction, the
authorized capitalization of the Borrower and each of its Subsidiaries, the
number of shares of each class of capital stock of each thereof issued and
outstanding and the number and percentage of outstanding shares of each such
class of capital stock owned by the Borrower or any of its Subsidiaries.  Upon
consummation of the Transaction the outstanding shares of the Borrower and each
of its Subsidiaries (other than the Unrestricted Subsidiaries) will have been
duly authorized and validly issued and are fully paid and nonassessable.  Upon

the Unrestricted Subsidiaries) each will own beneficially and of record and have

clear of any Lien. Except as set forth on Schedule 4.09, upon consummation of
the Transaction, there will be no options, warrants, calls, subscriptions,
conversion rights, exchange rights, preemptive rights or other rights,
agreements or arrangements (contingent or other) which may in any circumstances
now or hereafter obligate the Borrower or any of its Subsidiaries (other than
the Unrestricted Subsidiaries) to issue any shares of its capital stock or any
other securities. Upon consummation of the Transaction, the Borrower will have
no Significant Subsidiaries other than KAP and none of the Unrestricted
Subsidiaries (other than Koppers Hickson and its Subsidiaries, collectively)
will be Significant Subsidiaries with respect to KAP.

available to the Banks for each Plan and fairly presents the funding status of
each Plan.  There has been no material deterioration in any Plan's funding

date hereof a list of (a) all Australian superannuation  plans to which KAP or

Unrestricted Subsidiaries). The Borrower, the Borrower's Subsidiaries, KAP and
KAP's Subsidiaries (other than the Unrestricted Subsidiaries) each has good and
marketable title to all real property purported to be owned by it and good and

expected to have, a Material Adverse Effect, and the Borrower's, the Borrower's
Subsidiaries', KAP's and KAP's Subsidiaries' (other than the Unrestricted
Subsidiaries) use thereof conforms in all material respects to all Laws

               --------- 

         Except as stated on Schedule 4.12, none of the Borrower, any of the
Borrower's Subsidiaries, KAP or any of KAP's Subsidiaries (other than the

reserves and provisions for taxes on the books of the Borrower, each of the
Borrower's Subsidiaries, KAP and each of KAP's Subsidiaries for all open years
and for its current fiscal period are adequate in accordance with GAAP. None of
the Borrower, any of the Borrower's Subsidiaries, KAP or any of KAP's
Subsidiaries (other than the Unrestricted Subsidiaries) knows of any proposed

          5.02.  Conditions to All Extensions of Credit.
                 -------------------------------------- 

          The agreement of each Bank Party to make any Loan or issue any Letter
of Credit on any date (including the Closing Date) is subject to the
satisfaction of the following conditions precedent as of the date such Loan is
made or Letter of Credit is issued (or deemed to be issued):

          (a)  Notice.  In the case of any Loan, appropriate Standard Notice
               ------                                                       
shall have been given by the Borrower before such date as provided in Section
2.04.

          (b)  Representations and Warranties.  Each of the representations and
               ------------------------------                                  
warranties made by the Borrower and each Guarantor in or pursuant to this
Agreement or the Related Documents shall be true and correct in all material
respects on and as of such date as if made on and as of such date (in the case
of the Loans to be made or Letters of Credit to be issued on the Closing Date,
after giving effect to the Transaction).

          (c)  No Default.  No Event of Default or Potential Default shall have
               ----------                                                      
occurred and be continuing on such date or after giving effect to the Loan to be
made or Letter of Credit to be issued on such date (in the case of the Loans to
be made or Letters of Credit to be issued on the Closing Date, after giving
effect to the Transaction).

          (d)  No Violations of Law.  Neither the making nor use of any Loan or
               --------------------                                            
Letter of Credit (or the proceeds of any thereof) shall cause any Bank Party to
be in violation of any Law.

          Each Request by the Borrower that a Loan be made or Letter of Credit
be issued shall constitute a representation and warranty by the Borrower as of
the date of such
<PAGE>
 
                                      -95-

request that the conditions contained in this subsection 5.02 have been
satisfied. Failure of the Administrative Agent, an Issuing Bank or the Swingline
Bank, as the case may be, to receive notice from the Borrower to the contrary
before such Loan is made or Letter of Credit is issued shall constitute a
further representation and warranty by the Borrower that the conditions referred
to in this Section 5.02 have been satisfied as of the date such Loan is made or
such Letter of Credit is issued.

          5.03.  Additional Conditions to Issuances of Letters of Credit.

forth in Sections 3.01 and 3.03.

position for such fiscal quarter, in conformity with GAAP (other than with
respect to any Managing Directors' Reports) applied in a manner consistent with
that of the most recent audited financial statements furnished to the Banks,
subject to normal and recurring year-end audit adjustments.  Simultaneously with
the delivery to the Administrative Agent of the financial statements required by
this Section 6.01(b), the Borrower shall also furnish to the Administrative

          (c)  maintain in effect all such workers' compensation, disability
     benefits and similar insurance as may be required under the laws of any

maintain or cause to be maintained in full force and effect all patents, patent
applications, trademarks, service marks and applications therefor, trade names,

          (b)  on or prior to the date when due, all lawful claims of
     materialmen, mechanics, carriers, warehousemen, landlords and other like
     persons which, if unpaid, might result in the creation of a Lien upon any
     such property; and

          (c)  on or prior to the date when due, all other lawful claims which,
     if unpaid, might result in the creation of a Lien upon any such property
     (other than Permitted Liens) or which, if unpaid, might give rise to a
     claim entitled to priority over general creditors of the Borrower or such
     Subsidiary in a case under Title 11 (Bankruptcy) of the United States Code,
     as amended, or in any insolvency proceeding or dissolution or winding-up
     involving the Borrower or such Subsidiary;

provided that, unless and until foreclosure, distraint, levy, sale or similar
proceedings shall have been commenced, the Borrower or such Subsidiary need not
pay or discharge any such tax, assessment, charge, levy, claim or current
liability so long as the validity thereof is contested in good faith and by
appropriate proceedings diligently conducted, and so long as such reserves or
other appropriate provisions as may be required by GAAP shall have been made
therefor, and so long as such failure to pay or discharge does not have, and
would not reasonably be expected to have, a Material Adverse Effect.  The
Borrower shall promptly notify the Administrative Agent in writing if it or any
of its Subsidiaries learns of any material proposed additional assessment or
basis for any material assessment for additional taxes (whether or not reserved
against).

                 ---------------------

omissions, conditions or circumstances which result or may result in "Pre-
Closing Environmental Claims" or "Pre-Closing Environmental Cleanup Liability"
as defined in the Acquisition Agreement, the Borrower shall use all reasonable
efforts to prevent the deposit, emission, discharge or release by Borrower of
any Hazardous Substances on its properties, unless such deposit, emission,
discharge or release is authorized by, and in full compliance with (including by
the giving of all necessary financial assurances) a duly issued permit, license,

Substances and to provide for post-closure care of the same; (iii) to undertake
any cleanup or remediation of areas on any of its properties in or on which
Hazardous Substances were or are generated, handled, stored, treated or disposed
of; or (iv) otherwise required by any Official Body as a condition of the

arising from or relating to acts, omissions, conditions or circumstances covered
under Article VII of the Acquisition Agreement; provided that the Borrower shall
not be liable for any such liability, obligation, loss or damage to the extent

                 ------------------------- 

          In the event that any person becomes a Significant Subsidiary,
directly or indirectly, of the Borrower after the Closing Date (each such
Significant Subsidiary referred to herein as an "Additional Credit Party" and
collectively as the "Additional Credit Parties"), then, promptly after such
person becomes a Significant Subsidiary of the Borrower, the Borrower shall
notify the Administrative Agent and the Collateral Agent and shall cause such
Significant Subsidiary to execute and deliver all such agreements, guarantees,
pledges, assignments, documents and certificates (including any amendments to
the Related Documents) as the Administrative Agent or the Collateral Agent may
request and do such
<PAGE>
 
                                     -107-

other acts and things as the Administrative Agent or the Collateral Agent may
request in order to have such Significant Subsidiary guarantee the Obligations
and grant to the Collateral Agent ratably on behalf of the Banks, a duly
perfected Lien (subject to no Liens other than Permitted Liens and Liens
expressly permitted by the applicable Security Documents) on all real property
and personal property of such Significant Subsidiary and effect fully the
purposes of this Agreement and the other Related Documents and to provide for
payment of the Obligations in accordance with the terms of this Agreement and
the other Related Documents. Without limiting the generality of the foregoing,
in such event, such Additional Credit Party shall execute and deliver to the
Administrative Agent or the Collateral Agent, as appropriate, all Security
Documents as the Administrative Agent or the Collateral Agent may deem necessary
or appropriate to grant the Collateral Agent a security interest in all property
of such Additional Credit Party that would have constituted Collateral if such
Significant Subsidiary were a Credit Party on the Closing Date. For the purposes
of this Section 6.14, KAP Investments Inc. will be deemed to become a
Significant Subsidiary (and shall no longer be an Unrestricted Subsidiary) on
May 31, 1998 unless the Borrower shall have acquired and retired to treasury all
capital stock of the Borrower owned by KAP Investments Inc. prior to such date.

          6.15.  Certain Post-Closing Deliveries.

real properties of the Borrower listed on Schedule 4.11 that are not subject to
a Mortgage to deliver lien waiver and collateral access agreements, in form and
substance reasonably satisfactory to the Administrative Agent and the Collateral
Agent, and (ii) deliver or cause to be delivered to the Collateral Agent within
30 days following the Closing Date effective title insurance policies with
respect to Mortgages for which the Borrower has provided written evidence to the
Collateral Agent that Borrower has requested a title insurance commitment prior
to the date of this Agreement but for which the title company has not produced a
title insurance commitment as of the Closing Date.

          7.02.  Liens.
                 ----- 

          The Borrower shall not, and shall not permit any of its Consolidated

          (c)  Deposits or pledges to secure workers' compensation, unemployment
     insurance or other social security obligations, or in connection with or to

     pledges or deposits of like nature, all in the ordinary course of business;

          (d)  Zoning restrictions, easements, minor restrictions on the use of
     real property, minor irregularities in title thereto and other minor Liens
     that do not secure the payment of money or the performance of an obligation

     property or asset to, or materially impair its use in the business of, the
     Borrower or such Subsidiary;

            (i)   such Lien is created before or substantially simultaneously
     with the purchase of such property in the ordinary course of business of
     the Borrower or such Subsidiary (or is a Lien securing successor
     obligations incurred to extend or refinance predecessor obligations allowed
     under this Section 7.02(f); provided that in each case the successor
     obligation is an obligation of the same person subject to the predecessor
     obligation, is not greater than (and is not otherwise on terms less
     advantageous than) the predecessor obligation, and the Lien securing the
     successor obligation does not extend to any property other than that
     subject to the Lien securing the predecessor obligation);

            (ii)  such Lien is confined solely to the property so purchased,
     improvements thereto and proceeds thereof;
<PAGE>
 
                                     -110-

            (iii) the aggregate amount secured by all such Liens on any
     particular property at the time purchased by the Borrower or such
     Subsidiary, as the case may be, does not exceed the lesser of the purchase
     price of such property or the fair market value of such property at the
     time of purchase thereof ("purchase price" for this purpose including the
     amount secured by each such Lien thereon whether or not assumed); and

            (iv)  the obligation secured by such Lien is Indebtedness permitted
     under Section 7.03(h) or Indebtedness incurred by KAP or any of its
     Consolidated Subsidiaries in connection with the purchase of goods in the
     ordinary course of business;

Currency Agreements.

          Notwithstanding the foregoing, "Permitted Lien" shall in no event
include any Lien imposed by, or required to be granted pursuant to, ERISA, the

do any of the foregoing, except for the following ("Permitted Indebtedness"):

     customary trade terms and arising out of transactions (other than
     borrowings) in the ordinary course of business;

such branch, subsidiary or affiliate or such Participant, including all funds in
all deposit accounts (whether time or demand, general or special, provisionally
credited or finally credited, or otherwise) now or hereafter maintained by the
Borrower with such Bank Party or such branch, subsidiary or affiliate or such
Participant.  Such right shall be absolute and unconditional and, without
limitation, shall exist whether or not such Bank Party or such branch,
subsidiary or affiliate or such Participant shall have given notice or made any
demand hereunder or under any Related Document or under any participation,
whether or not such debt owing to or funds held for the account of the Borrower
is or are contingent or absolute or matured or unmatured, whether or not any
amounts owing to any Participant with respect to any participation are matured
or unmatured, whether or not any such branch, subsidiary or affiliate or
Participant is in privity with or is a creditor of the Borrower, and regardless
of the existence or adequacy of any collateral, guaranty or any other security,
right or remedy available to any Bank Party or Participant.  Such right shall
exist regardless of the currency in which is expressed such debt owing to or
such funds held for the account of the Borrower, and if such debt is or such
funds are expressed in a currency (the "Set-off Currency") other than the
currency payable hereunder (the "Contractual Currency"), for purposes of
effecting set-off the rate of exchange used shall be that at which in accordance
with normal banking procedures such Bank Party or such branch, subsidiary or
affiliate or such Participant could
<PAGE>
 
                                     -130-

purchase the Contractual Currency with the Set-off Currency on the Business Day
following such set-off.  The Borrower hereby consents to and confirms the
foregoing arrangements and confirms each Bank Party's rights, and each branch's
subsidiary's and affiliate's rights, and each Participant's rights, of banker's
lien and set-off.  The rights provided by this Section are in addition to all
other rights of set-off and banker's lien and all other rights and remedies
which any Bank Party (or any branch, subsidiary or affiliate or any Participant)
may otherwise have under this Agreement, any Related Document, at law, in equity
or otherwise, and nothing in this Agreement or in any of the Related Documents
shall be deemed to be a waiver or prohibition of or restriction on any Bank
Party's rights, or any branch's, subsidiary's or affiliate's rights, or any
Participant's rights, of banker's lien or set-off.

          8.04.  Application of Proceeds.
                 ----------------------- 

          Any amount received by any Bank Party, whether as the result of any
voluntary payment or prepayment, upon the exercise of any right of set-off or
banker's lien, by counterclaim, or by any other source, shall be applied against
the Obligations as follows:

          (a)  first, to payment in full of all fees, indemnities and other
     amounts due to the Agents in their respective capacities as such;

          (b)  second, to payment in full of all fees, indemnities and other
     amounts due to the Issuing Banks and the Swingline Bank in their capacities
     as such, other than principal of or interest on Swingline Loans and Letter
     of Credit Reimbursement Obligations, ratably amongst the Issuing Banks and
     the Swingline Bank in proportion to the respective amounts described in
     this clause "second" due to them;

          (c)  third, to payment in full of all fees (other than fees in respect
     of Letters of Credit pursuant to Section 3.02(a)) and expenses due
     hereunder or under any of the Related Documents and not paid pursuant to
     clause (a) or (b) above;

          (d)  fourth, to payment in full of all interest then due on
     outstanding Loans and Letter of Credit Unreimbursed Draws and Swingline
     Loans and to payment in full of all fees in respect of Letters of Credit
     pursuant to Section 3.02(a);

          (e)  fifth, to payment in full of all principal of outstanding Loans,
     Letter of Credit Unreimbursed Draws and Swingline Loans, ratably among the
     Banks, the Issuing Banks and the Swingline Bank in proportion to the
     respective amounts described in this clause "fifth" due to them;

          (f)  sixth, to funding of the Letter of Credit Collateral Account in
     accordance with the provisions hereof;
<PAGE>
 
                                     -131-

          (g)  seventh, to payment in full of any and all other amounts due 
     hereunder or under any of the Related Documents in respect of the
     Commitments, the Loans, the Letters of Credit or otherwise; and

          (h)  thereafter, to the Borrower or as otherwise required by Law.

          8.05.  Equalization Among Bank Parties and Participants.
                 ------------------------------------------------ 

          The Bank Parties and the Participants hereby agree among themselves
that, if any Bank Party or Participant shall receive (whether by voluntary
payment, realization upon security, set-off or from any other source) any amount
on account of any part of the Obligations which is in excess of the share
thereof to which such Bank Party or Participant is entitled pursuant to the
terms of this Agreement, then the Bank Party or Participant receiving such
excess amount shall notify the other Bank Parties and Participants which may be
entitled to a share thereof and the Administrative Agent of such receipt, and
equitable adjustment will be made in the manner stated in this Section so that,
in effect, all such excess amounts are shared Pro Rata among the Bank Parties
and Participants.  The Bank Party or Participant receiving any such excess
amount shall purchase (which it shall be deemed to have done simultaneously with
the receipt of such excess amount) for cash from the other Bank Parties and
Participants, as the case may be, an interest in the Obligations owing to each
other Bank Party or Participant in such amount as shall result in a Pro Rata
participation by all Bank Parties and Participants in such excess amount (and to
the extent of any such sharing, the Bank Party or Participant receiving such
interest shall be deemed to be a Participant); provided, however, that if all or
any portion of such excess amount shall thereafter be recovered from the Bank
Party or Participant making such purchase, such purchase shall be rescinded and
the purchase price restored to the extent of such recovery, together with
interest or other amounts, if any, required by Law (including court order) to be
paid by such Bank Party or Participant, as the case may be.


                                  ARTICLE IX.

                                  THE AGENTS
                                  ----------

          9.01.  Appointment.
                 ----------- 

          The Bank Parties hereby irrevocably appoint SBC Warburg Dillon Read
Inc. to act as their Arranger and Syndication Agent, Mellon Bank, N.A. to act as
their Administrative Agent and Collateral Agent and Swiss Bank Corporation to
act as their Documentation Agent hereunder and under the Related Documents as
herein specified.  Each Bank Party hereby irrevocably authorizes the Agents to
take such action on its behalf under the provisions of this Agreement and the
Related Documents, and to exercise such powers and to perform such
<PAGE>
 
                                     -132-

duties hereunder and thereunder, as are specifically delegated to or required of
the Agents by the terms hereof or thereof, together with such powers as are
reasonably incidental thereto.  Each of the Agents hereby agrees to act in its
respective capacities on behalf of the Bank Parties on the terms and conditions
set forth in this Agreement and the Related Documents.  Each Bank Party hereby
irrevocably authorizes the Agents to execute and deliver each of the Related
Documents as an Agent and to accept delivery of such of the other Related
Documents as may not require execution by the Agents.  Each Bank Party hereby
agrees that the rights and remedies granted to the Agents hereunder and under
the Related Documents shall be exercised exclusively by the Agents, and that no
Bank Party shall have any right individually to exercise any such right or
remedy, except to the extent, if any, expressly provided herein or therein.

          9.02.  Delegation of Duties.
                 -------------------- 

          Each of the Agents may perform any of its duties hereunder or under
the Related Documents by or through agents or employees.  None of the Agents
shall be responsible for the negligence or misconduct of any agents selected by
it with reasonable care.  Each of the Agents may consult with legal counsel
(including counsel for such Agent or in-house or other counsel for the
Borrower), independent public accountants and any other experts selected by it
from time to time, and any such Agent shall not be liable to the Bank Parties
for any action taken or omitted to be taken in good faith by it in accordance
with the advice of such counsel, accountants or experts.

          9.03.  Nature of Duties; Independent Credit Investigation.
                 -------------------------------------------------- 

          (a)  The Agents shall have no duties or responsibilities except those
expressly set forth in this Agreement or the Related Documents, and no implied
duties or responsibilities on the part of the Agents shall be read into this
Agreement or any Related Document or shall otherwise exist.  The duties and
responsibilities of each of the Agents under this Agreement and the Related
Documents shall be mechanical and administrative in nature; the Agents shall not
by reason of this Agreement or any of the Related Documents have a fiduciary
relationship in respect of any Bank Party; and nothing in this Agreement or any
Related Document, expressed or implied, is intended to or shall be so construed
as to impose upon any of the Agents any obligations in respect of this Agreement
or any Related Document except as expressly set forth herein or therein.

          (b)  The Agents are and shall be solely the agents of the Bank
Parties.  The Agents do not assume, and shall not at any time be deemed to have,
any relationship of agency or trust with or for, or any other duty or
responsibility to, the Borrower or any person other than the Bank Parties.  The
provisions of this Article IX are for the benefit of the Bank
<PAGE>
 
                                     -133-

Parties (and the other persons named in Section 9.06), and the Borrower shall
not have any rights under any of the provisions of this Article IX.

          (c)  Each Bank Party expressly acknowledges (i) that the Agents have
not made any representation or warranty to it, and that no act by the Agents
heretofore or hereafter taken, including any review of the affairs of the Credit
Parties, shall be deemed to constitute any representation or warranty by the
Agents to any Bank Party; (ii) that, independently and without reliance upon the
Agents, and based upon such documents and information as it has deemed
appropriate, it has made its own independent investigation of the financial
condition and affairs, and its own appraisal of the creditworthiness, of the
Credit Parties, and its own credit and legal analysis and decision to enter into
this Agreement and the Related Documents; (iii) that, independently and without
reliance upon the Agents, and based upon such documents and information as it
shall deem appropriate at the time, it will continue to make its own decisions
to take or not take action under or in connection with this Agreement or the
Related Documents; and (iv) that the Agents have and shall have no duty or
responsibility, either initially or on a continuing basis, to provide it with
any credit or other information, except as otherwise expressly provided herein,
whether coming into their possession before the making of any Loans or issuance
of any Letters of Credit hereunder or at any time or times hereafter.

          9.04.  Actions in Discretion of Agents; Instructions
                 from Banks.
                 ---------------------------------------------

          Each of the Agents agrees, upon the written request of the Required
Banks, to take any action of the type specified as being within such Agent's
rights, powers or discretion herein or in the Related Documents; provided,
however, that such Agent shall be under no obligation to take any action
hereunder or under any Related Document if such Agent believes in good faith
that taking such action may conflict with any Law or any provision of this
Agreement or any Related Document or may require such Agent to qualify to do
business in any jurisdiction where it is not then so qualified.  In the absence
of a request by the Required Banks, each of the Agents shall have authority (but
under no circumstances shall be obligated), in its sole discretion, to take or
not to take any such action, unless this Agreement or the Related Documents
specifically require the consent of the Required Banks, in which case such Agent
shall not take such action absent such direction or consent.  Any action taken
or failure to act pursuant to such instructions or discretion shall be binding
on all the Bank Parties.  No Bank Party shall have any right of action against
any of the Agents, and none of the Agents shall have any liability to any person
as a result of (a) acting or refraining from acting in accordance with the
directions of the Required Banks, (b) refraining from acting in the absence of
instructions to act from the Required Banks, whether or not such Agent has
discretionary power to take such action, or (c) taking discretionary action it
is authorized to take under this Section 9.04, subject to the provisions of
Section 9.05.

          9.05.  Exculpatory Provisions.
                 ---------------------- 

          (a)  None of the Agents nor any of their respective directors,
officers, employees or agents shall be liable to any of the Agents or any Bank
Party for any action taken or omitted to be taken by it hereunder or under any
of the Related Documents or in connection herewith or therewith, unless caused
by its own gross negligence or willful misconduct, as finally determined by a
court of competent jurisdiction.

          (b)  In performing its functions and duties hereunder or under the
Related Documents on behalf of the Bank Parties, each Agent shall exercise the
same care which it would exercise in dealing with loans for its own account, but
it shall not be responsible in any manner to any of the Bank Parties for (i) the
execution, delivery, effectiveness, enforceability, genuineness, validity or
adequacy of this Agreement or any of the Related Documents, (ii) any recital,
representation, warranty, document, certificate, report or statement herein or
therein or made or furnished under or in connection with this Agreement or any
Related Document, (iii) any failure of the Borrower or any other person to
perform any of their respective obligations under this Agreement or any of the
Related Documents, (iv) the existence, validity, enforceability, perfection,
recordation, priority, adequacy or value, now or hereafter, of any Lien or other
direct or indirect security afforded or purported to be afforded by any of the
Security Documents or otherwise from time to time, or (v) caring for,
protecting, insuring, or paying any taxes, charges or assessments with respect
to, any Collateral.

          (c)  None of the Agents shall be under any obligation to ascertain,
inquire or give any notice relating to (i) the performance or observance of any
of the terms or conditions of this Agreement or any of the Related Documents on
the part of the Borrower or any other person, (ii) the business, operations,
condition (financial or otherwise) or prospects of the Borrower or any other
person, or (ii) except to the extent set forth in Section 9.05(e), the existence
of any Event of Default or Potential Default.

          (d)  None of the Agents shall be under any obligation to any of the
Bank Parties, either initially or on a continuing basis, to provide any Bank
Party with any notices, reports or information of any nature, whether in its
possession presently or hereafter, except for such notices, reports and other
information expressly required by this Agreement or any of the Related Documents
to be furnished by such Agent to such Bank Party.

          (e)  None of the Agents shall be under any obligation to any of the
Bank Parties, either initially or on a continuous basis, to ascertain the
existence or possible existence of any Event of Default or Potential Default and
none of the Agents shall be deemed to have knowledge of the occurrence of an
Event of Default or Potential Default unless a required payment by the Borrower
to such Agent has not been made or such Agent
<PAGE>
 
                                     -135-

has received notice from another Bank Party or the Borrower specifying such
Event of Default or Potential Default and stating that such notice is a "Notice
of Default."  In the event that the Administrative Agent fails to so receive any
such payment or receives any such notice, the Administrative Agent shall give
prompt notice thereof to the other Bank Parties.

          9.06.  Reimbursement and Indemnification.
                 --------------------------------- 

          Each Bank severally agrees to reimburse and indemnify each of the
Agents in their respective capacities as such and each of their respective
directors, officers, employees and agents (to the extent not reimbursed by the
Borrower), Pro Rata for all Proportions, for and against any and all
liabilities, obligations, losses (other than any losses resulting from a failure
by the Administrative Agent to receive from the Borrower any amount owing
pursuant to Section 9.13), damages, penalties, actions, judgment, suits, costs,
expenses or disbursements of any kind or nature whatsoever (including the fees
and disbursements of counsel for each of the Agents or such other person in
connection with any investigative, administrative or judicial proceeding
commenced or threatened, whether or not such Agent or such other person shall be
designated a party thereto) which may at any time be imposed on, incurred by or
asserted against each Agent, in its capacity as such, or such other person as a
result of, or arising out of, or in any way related to or by reason of, this
Agreement or the Related Documents, any transaction from time to time
contemplated hereby or thereby, or any transaction financed in whole or in part
or directly or indirectly with any Loans or Letters of Credit (or the proceeds
of any thereof); provided, that no Bank shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements to the extent that they result from an Agent's
or such other person's gross negligence or willful misconduct, as finally
determined by a court of competent jurisdiction.

          9.07.  Administration by the Agents.
                 ---------------------------- 

          (a)  Each of the Agents shall be entitled to rely upon any writing,
facsimile transmission, telegram, telex or teletype message, resolution, notice,
consent, certificate, letter, cablegram, statement, order or other document or
conversation by telephone or otherwise (whether or not such communication is
made in a manner permitted or required by this Agreement or any Related
Document) believed by it to be genuine and correct and to have been signed, sent
or made by the proper party or parties, and each of the Agents shall have no
duty to verify the identify or authority of any person giving any such
communication.  Each of the Agents may conclusively rely upon the truth of the
statements and the correctness of the opinions expressed in any certificates or
opinions furnished to such Agent in accordance with the requirements of this
Agreement or any of the Related Documents.  Whenever an Agent shall deem it
necessary or desirable that a matter be proved or established with respect to
the Borrower, any of its Subsidiaries or any other Bank Party, such matter may
be
<PAGE>
 
                                     -136-

established by a certificate of the Borrower or such other Bank Party, as the
case may be, and such Agent may conclusively rely upon such certificate (unless
other evidence with respect to such matter is specifically prescribed in this
Agreement or any of the Related Documents).  Each of the Agents may fail or
refuse to take any action unless it shall be indemnified to its satisfaction
from time to time against any and all amounts, liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature which may be imposed on, incurred by or asserted against
such Agent by reason of taking or continuing to take any such action.

          9.08.  The Agents in Their Respective Individual Capacities.
                 ---------------------------------------------------- 

          Each of the Agents shall have the same rights and powers hereunder and
under the Related Documents as any other Bank Party and may exercise the same as
though it were not an Agent, and the terms "Banks," "Bank Parties" or "holders
of Notes" shall, unless the context hereof otherwise indicates, include any of
the Agents in their individual capacities.  Except as otherwise provided herein,
each of the Agents and its affiliates may, without liability to account, make
loans to, accept deposits from, acquire debt or equity interests in, act as
trustee under indentures of, and generally engage in any other kind of business
with, the Borrower and its Subsidiaries and their respective stockholders and
affiliates as though it were not acting as an Agent.

          9.09.  Holders of Notes.
                 ---------------- 

          Each of the Agents may deem and treat any Bank payee of any Note as
the owner of such Note for all purposes hereof, unless and until a Transfer
Supplement with respect to the assignment or transfer thereof shall have been
filed with the Agents in accordance with Section 10.12.  Any request, authority,
direction or consent of any person who at the time of making such request or
giving such authority, direction or consent was a Bank shall be conclusive and
binding on any present or subsequent holder, transferee or assignee of such Note
or of any Note or Notes issued in exchange therefor.

          9.10.  Successor Agents.
                 ---------------- 

          (a)  Any of the Agents may resign at any time by giving ten (10) days'
prior written notice thereof to the other Bank Parties and the Borrower, such
resignation to be effective on the date specified in such notice, and on such
date, the resigning Agent shall be automatically discharged from its duties
under this Agreement and the Related Documents without requirement of any
further action by such resigning Agent.  Any of the Agents may be removed at any
time by the Required Banks, giving ten (10) days' prior written notice thereof
to the Agent, the other Bank Parties and the Borrower, such removal to be
effective
<PAGE>
 
                                     -137-

on the date specified in such notice and, on such date, the removed Agent shall
be automatically discharged from its duties under this Agreement and the Related
Documents without requirement of any further action by such removed Agent, the
other Bank Parties or the Borrower. Upon any such resignation or removal of an
Agent, the Required Banks shall have the right to appoint a successor Agent;
provided, however, that, so long as no Event of Default or Potential Default
hereunder shall have occurred and be continuing, any such appointment of a
successor Agent shall be subject to the prior written consent of the Borrower
not to be unreasonably withheld. If no successor Agent shall have been appointed
and accepted such appointment within ten (10) days after the resigning Agent's
notice of resignation or removed Agent's notice of removal, then the resigning
or removed Agent, on behalf of the other Bank Parties may, but shall not be
obligated to, appoint a successor Agent, which shall be either a Bank or a
commercial bank organized under the laws of the United States of America or any
state thereof and have a combined capital and surplus of at least
$1,000,000,000; provided, however, that so long as no Event of Default or
Potential Default shall have occurred and be continuing or shall exist, any such
appointment of a successor Agent shall be subject to the prior consent of the
Borrower not to be unreasonably withheld. Upon the appointment of a successor
Agent and acceptance by such successor Agent of its appointment, such successor
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the former Agent in its capacity as such, without
further act, deed or conveyance. Upon the effective date of resignation or
removal of an Agent, such Agent shall be discharged from its duties as such
under this Agreement and the Related Documents, but the provisions of this
Agreement and the Related Documents shall inure to its benefit as to any actions
taken or omitted by it while it was Agent. If and for so long as no successor
Agent shall have been appointed, then any notice or other communication required
or permitted to be given by such Agent shall be sufficiently given if given by
the Required Banks, all notices or other communications required or permitted to
be given to such Agent shall be given to each other Bank Party, all payments to
be made to such Agent shall be made directly to the Bank Party for whose account
such payment is required to be made, and any and all interests granted to such
Agent for the benefit of the Bank Parties under any of the Security Documents
shall be deemed to have been granted to the other Bank Parties.

          (b)  Notwithstanding any other provision of this Agreement or the
Related Documents to the contrary, none of the Agents nor any of their
respective directors, officers, employees or agents shall be liable to any other
Bank Party for any action taken or omitted to be taken by it under or in
connection with this Section 9.10.

          9.11.  Additional Agents.
                 ----------------- 

          If any of the Agents shall from time to time deem it necessary or
advisable, for its own protection in the performance of its duties hereunder or
in the interest of the other
<PAGE>
 
                                     -138-

Bank Parties, such Agent and the Borrower shall execute and deliver a
supplemental agreement and all other instruments and agreements necessary or
advisable, in the opinion of such Agent, to constitute another commercial bank
or trust company, or one or more other persons approved by such Agent, to act as
co-Agent or agent with respect to any part of the Collateral, with such powers
of such Agent as may be provided in such supplemental agreement, and to vest in
such bank, trust company or persons as such co-Agent or separate agent, as the
case may be, any properties, rights, powers, privileges or duties of such Agent
under this Agreement or the Related Documents.

          9.12.  Calculations.
                 ------------ 

          In the absence of gross negligence or willful misconduct, none of the
Agents shall be liable for any error in computing the amount payable to any Bank
Party, whether in respect of the Loans, Letters of Credit, fees or any other
amounts due to the Bank Parties under this Agreement or the Related Documents.
In the event an error in computing any amount payable to any Bank Party is made,
such Agent, the Borrower and each affected Bank Party shall, forthwith upon
discovery of such error, make such adjustments as shall be required to correct
such error, and interest on such adjusted amount will accrue as set forth in
Section 9.14.

          9.13.  Administrative Agent's Fee.
                 -------------------------- 

          The Borrower agrees to pay to the Administrative Agent as
consideration for its services as Administrative Agent hereunder such fees as
are set forth in a separate letter agreement between the Administrative Agent
and the Borrower.

          9.14.  Funding by Administrative Agent.
                 ------------------------------- 

          Unless the Administrative Agent shall have been notified in writing by
any Bank not later than the close of business on the day before the day on which
any Loan is requested by the Borrower to be made that such Bank will not make
its Pro Rata share of such Loan available, the Administrative Agent may assume
that such Bank will make its Pro Rata share of such Loan available, and in
reliance upon such assumption the Administrative Agent may (but in no
circumstances shall be required to) make available to the Borrower a
corresponding amount.  If and to the extent that any Bank fails to make such
amount available to the Administrative Agent on such date, such Bank shall pay
such amount on demand (or, if such Bank fails to pay such amount on demand, the
Borrower shall pay such amount on demand), together with interest, for the
Administrative Agent's own account, for each day from and including the date of
the Administrative Agent's payment to and including the date of repayment to the
Administrative Agent (before and after judgment) at the following rates per
annum:  (x) for each day from and including the date of such payment by
<PAGE>
 
                                     -139-

the Administrative Agent to and including the second Business Day thereafter, at
the Federal Funds Effective Rate of such day, and (y) for each day thereafter,
at the rate applicable to such Loans for such day. All payments to the agent
under this Section shall be made to the Administrative Agent at its Office in
Dollars in funds immediately available at such Office, without set-off,
withholding, counterclaim or other deduction of any nature.

due performance of the obligations of the Borrower hereunder or thereunder may
be given, with the consent of all or certain of the Bank Parties as follows:

           (i)   Any amendment, waiver or consent which would

                 (A) increase the Committed Amount of any Bank over the amount
          thereof then in effect, or extend the Revolving Credit Expiration Date
          or change any Scheduled Amortization Payment; or

     Revolving Credit Commitments then outstanding; and
 
           (ii)  Any amendment, waiver or consent which would extend the time
     for payment of or reduce the amount of any fee due and owing to any Bank
     party shall require the written consent of each Bank Party affected
     thereby; and

           (iii) Any other amendment or waiver of or consent to departure from
     the due performance by the Borrower of any covenant, representation,
     warranty or other term or provision hereof or of any of the Related
     Documents shall require the written consent of the Required Banks, except
     that no amendment to Article III may be made (and the rights, interests or
     obligations of the Issuing Banks and the Swingline Bank may not otherwise
     be changed), in the case of Sections 3.01 through 3.10, without the consent
     of the Issuing Banks and, in the case of Sections 3.11 through 3.14,
     without the consent of the Swingline Bank, and no amendment to Article IX
     may be made (and the rights, interests or obligations of any Agent may not
     otherwise be changed) without the consent of the Agent affected;

provided, however, that no agreement, waiver or consent may be made which would

     (w) release any Guarantor from its obligations pursuant to its Guarantee;
<PAGE>
 
                                     -141-

acting) may execute waivers or consents, each of which shall be effective to
bind all the Bank Parties.

          (c)  In the case of any waiver or consent relating to any provision
hereof or of the Related Documents, the parties shall be restored to their
positions authorized by such waiver or consent and their rights thereunder, and
any Potential Default or Event of Default so waived or consented to shall be
deemed to be cured and not continuing; but no such waiver or consent shall
extend to any other obligation or any subsequent or other Potential Default or
Event of Default or impair any right consequent thereon.

          (d)  Any such agreement, waiver or consent must be in writing and
shall be effective only to the extent specifically set forth in such writing.

          10.04.  No Implied Waiver; Cumulative Remedies.
                  -------------------------------------- 

          No course of dealing and no delay or failure of any of the Agents or
any other Bank Party in exercising any right, power or privilege under this
Agreement or any of the Related Documents shall affect any other or future
exercise thereof or the exercise of any other right, power or privilege; nor
shall any single or partial exercise of any such right, power or privilege or
any abandonment or discontinuance of steps to enforce such a right, power or
privilege preclude any further exercise thereof or of any other right, power or
privilege.  The rights and remedies of each of the Agents and the other Bank
Parties under the Agreement and the Related Documents are cumulative and are not
exclusive of any rights or remedies which the Agents or any other Bank Party
would otherwise have.

          10.06.  Expenses; Taxes; Attorneys' Fees.
                  --------------------------------

out-of-pocket costs and expenses, including fees and expenses of counsel,
including local counsel, auditors, and all other professional, accounting,

and the Related Documents (including the Commitment Letter) and the initial
syndication thereof (other than the fees of Reed Smith Shaw McClay LLP incurred
by Mellon Bank, N.A. in connection with the initial negotiation, preparation,

entered into or
<PAGE>
 
                                     -143-

granted) to or with respect to this Agreement or any of the Related Documents,

under this Agreement or any of the Related Documents, including (A) the

Agreement and the Related Documents.

          (b)  The Borrower hereby indemnifies the Bank Parties, their
respective affiliates, and the directors, officers, employees and agents of each
thereof, and the other banks and financial institutions which may be offered the
opportunity to participate in the financing contemplated by this Agreement, and
their respective affiliates, directors, officers, employees and agents, and each
of them (collectively, the "Indemnified Parties"), and agrees to hold each of
them harmless from and against any and all losses, claims, damages, expenses or
liabilities incurred by any of them or to which any of them may become subject,
insofar as such losses, claims, damages, expenses or liabilities (or actions,
suits or proceedings, including any inquiry or investigation or claims in
respect thereof) arise out of, result from, or in any way relate to, this
Agreement, any of the Related Documents, any transactions from time to time
contemplated hereby or thereby, or any transaction financed or secured in whole
or in part, directly or indirectly, with the proceeds of any Loan or any Letter
of Credit or the proceeds of any thereof (whether or not any Indemnified Party
is a party to any action or proceeding out of which any such losses, claims,
damages, expenses or liabilities arise), and to reimburse the Indemnified
Parties, upon demand, for any legal or other expenses incurred by any thereof in
or in connection with investigating, preparing to defend, defending or otherwise
participating in any such claim, action or proceeding relating to any such loss,
claim, damage or liability, except any such losses, liabilities, claims, damages
or expenses incurred by reason of the gross negligence or willful misconduct of
the person seeking such indemnification, as finally determined by a court of
competent jurisdiction.  If and to the extent that the foregoing obligations of
the Borrower under this Section 10.06(b), or any other indemnification
obligation of the Borrower hereunder or under any Related Document, shall be
unenforceable for any reason, the Borrower hereby agrees to make the maximum
contribution to the payment and satisfaction of such obligations which is
permissible under applicable Law.

          (c)  The Borrower agrees to pay all stamp, document, transfer,
recording, filing, registration, search, sales and excise taxes or fees and all
other similar impositions now or hereafter determined by any Bank Party to be
payable in connection with this Agreement or any of the Related Documents or any
other documents, instruments or transactions pursuant to
<PAGE>
 
                                     -144-

or in connection herewith or therewith and the Borrower agrees to save each Bank
Party harmless from and against any and all present or future claims,
liabilities or losses with respect to or resulting from any omission to pay or
delay in paying any such taxes, fees or impositions.

          10.07.  Limitation on Payments; Severability.
                  ------------------------------------ 

          (a)  Limitation on Payments.  The parties hereto intend to conform to
               ----------------------                                          
all applicable laws in effect from time to time limiting the maximum rate of
interest that may be charged or collected.  Accordingly, notwithstanding any
other provision hereto or of any Related Document, the Borrower shall not be
required to make any payment to or for the account of any Bank Party, and each
Bank Party shall refund any payment made by the Borrower, to the extent that
such requirement or such failure to refund would violate or conflict with the
nonwaivable provisions of any applicable Law limiting the maximum amount of
interest which may be charged or collected by such Bank Party.

          (b)  Severability.  The provisions of this Agreement are intended to
               ------------                                                   
be severable.  If any provision of this Agreement shall be held invalid or
unenforceable in whole or in part in any jurisdiction, such provision shall, as
to such jurisdiction, be ineffective to the extent of such invalidity or
unenforceability without in any manner affecting the validity or enforceability
thereof in any other jurisdiction or the remaining provisions hereof in any
jurisdiction.

          10.08.  Government Law; Submission to Jurisdiction; Waiver
                  of Jury Trial; Limitation of Liability.

     ANY CLAIM THAT ANY SUCH RELATED LITIGATION HAS BEEN BROUGHT IN AN
     INCONVENIENT FORUM, AND WAIVES ANY RIGHT TO OBJECT, WITH RESPECT TO ANY
     RELATED LITIGATION BROUGHT IN ANY SUCH COURT, THAT SUCH COURT DOES NOT HAVE
     JURISDICTION OVER THE BORROWER;

            (iii) CONSENTS AND AGREES TO SERVICE OF ANY SUMMONS, COMPLAINT OR
     OTHER LEGAL PROCESS IN ANY RELATED LITIGATION BY REGISTERED OR CERTIFIED
     U.S. MAIL, POSTAGE PREPAID, TO THE BORROWER AT THE ADDRESS FOR NOTICES
     DESCRIBED IN SECTION 10.05, AND CONSENTS AND AGREES THAT SUCH SERVICE SHALL

     MANNER PERMITTED BY LAW); AND

            (iv)  WAIVES THE RIGHT TO TRIAL BY JURY IN ANY RELATED LITIGATION.

          (c)  LIMITATION OF LIABILITY.  TO THE FULLEST EXTENT PERMITTED BY LAW,

HEREWITH OR THEREWITH (WHETHER FOR BREACH OF CONTRACT, TORT OR ON ANY OTHER
THEORY OF LIABILITY).  THE BORROWER HEREBY WAIVES, RELEASES AND AGREES NOT TO

ARISES HEREAFTER AND WHETHER OR NOT SUCH CLAIM IS KNOWN OR SUSPECTED TO EXIST IN
ITS FAVOR.

          10.09.  Prior Understanding.
                  ------------------- 

          This Agreement and the Related Documents supersede all prior and
contemporaneous understandings and agreements, whether written or oral, among
the parties hereto relating to the transactions provided for herein and therein,
including the Commitment Letter, except for (a) the obligation of the Borrower
to pay the underwriting fee as set forth in the Underwriting Fee Letter
constituting part of the Commitment Letter, and (b) the obligation of the
Borrower to pay the arrangement fee as set forth in the Arrangement Fee Letter
which is a part of the Commitment Letter.

          10.10.  Duration; Survival.
                  ------------------ 

          All representations and warranties of the Borrower contained herein
and in the Related Documents or made in connection herewith or therewith shall
survive the making of and shall not be waived by the execution and delivery of
this Agreement or any of the Related Documents, any investigation by or
knowledge of any Bank Party, the making of any Loan, the issuance (including any
deemed issuance pursuant to Section 3.10 or arising from any increase or
extension of any outstanding Letter of Credit pursuant to Section 3.03(b)) of
any Letter of Credit or any other event or condition whatsoever.  All covenants
and agreements of the Borrower contained herein or in any Related Document shall
continue in full force and effect from and after the date hereof until all
Commitments have terminated, all Letters of Credit have expired or have been
terminated and all other Obligations have been indefeasibly paid in full in
cash.  Without limitation, it is understood that all obligations of the Borrower
to make payments to or indemnify the Bank Parties (including obligations arising
under Sections 2.11, 2.12 and 10.06) shall survive the payment in full of all
other Obligations, termination of the Borrower's right to borrow hereunder and
all other events and conditions whatsoever.  In addition, all obligations of
each Bank to make payments to or indemnify the Agents, the Issuing Banks or the
Swingline Bank and persons related to the Agents, the Issuing Banks or the
Swingline Bank (including but not limited to obligations arising under Sections
2.11, 2.12, 3.08(c), 3.14(c) and 10.06) shall survive the payment in full by the
Borrower of all other Obligations, termination of the Borrower's right to borrow

          10.11.  Counterparts.
                  ------------ 

          This Agreement may be executed in any number of counterparts and by
the different parties hereto on separate counterparts, each of which, when so
executed, shall be deemed an original, but all such counterparts together shall
constitute but one and the same instrument.

          10.12.  Successors and Assigns; Participations; Assignments.
                  --------------------------------------------------- 

          (a)  Successors and Assigns.  This Agreement shall be binding upon and
               ----------------------                                           
inure to the benefit of the Borrower, the Bank Parties and their respective
successors and assigns, except that the Borrower may not assign or transfer any
of its rights hereunder without the prior written consent of all the Bank
Parties, and any purported assignment without such consent shall be void, and
except that, to the fullest extent permitted by Law, a Bank Party may not
voluntarily assign or transfer any of its rights hereunder except in accordance
with the other provisions of this Section 10.12, and any other purported
voluntary assignment or transfer shall be void; provided that this Agreement
shall inure to the benefit of successors to the Bank parties by operation of Law
or resulting from an involuntary assignment or transfer (including the
appointment of a receiver, conservator, trustee or like person) and any
successor by merger or consolidation. Except to the extent otherwise required by
the context of this Agreement, the word "Bank" or "Bank Party" where used in
this Agreement shall mean and include any holder of any Note originally issued
to any Bank hereunder, and each such holder of a Note shall be bound by and have
the benefits of this Agreement the same as if such holder had been a signatory
hereto.

          (b)  Participations.  Any Bank may, in the ordinary course of its
               --------------                                              
business and in accordance with applicable Law, at any time sell to one or more
additional banks or financial institutions ("Participants") participating
interests in all or a portion of any Loan or Letter of Credit Reimbursement
Obligation owing to such Bank, any Note, Letter of Credit Participating Interest
or Swingline Participating Interest held by such Bank, any Commitment of such
Bank or any other interest of such Bank hereunder.  In the event of any such
sale by a Bank of participating interests to a Participant, such Bank's
obligations under this Agreement to the other parties to this Agreement and the
Related Documents shall remain unchanged, such Bank shall remain solely
responsible for the performance thereof, such Bank shall remain the holder of
any such Note for all purposes of this Agreement and the Related Documents, and
the other parties hereto shall continue to deal solely and directly with such
Bank in connection with such Bank's rights and obligations under this Agreement
and the Related Documents.  The Borrower hereby consents to and confirms the
foregoing arrangements and hereby confirms each Bank's right without notice to
or consent of the Borrower to create or dispose of participations in the
Obligations as contemplated by this Section 10.12(b) (whether such
participations are in the form of partial or complete assignments of such Bank
Party's rights hereunder or under the Related Documents, creation of a debtor-
creditor or trustee-beneficiary relationship between such Bank Party and such
Participants or otherwise).  The Borrower also agrees that each Participant
shall be entitled to the benefits of Sections 2.06(f), 2.11, 2.12, 2.13 and 9.06
with respect to its participation in the Commitments and the Loans and Letter of
Credit Reimbursement Obligations outstanding from time to time; provided that no
Participant shall be entitled to receive any greater amount pursuant to such
Sections than the transferor Bank would have been entitled to receive in
<PAGE>
 
                                     -148-

respect of the amount of the participation transferred by such transferor Bank
to such Participant had no such transfer occurred. A Bank may agree with any
Participant not to consent to any amendment to or waiver under this Agreement
which would require the written consent of 100% of the Banks without the consent
of such Participant, but a Bank may not agree with a Participant not to consent
to any other amendment or waiver under this Agreement.

          (c)  Sales to Purchasing Banks.  Any Bank may, in the ordinary course
               -------------------------                                       
of its commercial banking business and in accordance with applicable Law, at any
time assign to any other Bank, any affiliate of itself or of any Bank which is
wholly owned by a common parent corporation or, subject to the limitations set
forth in the proviso to this sentence, to one or more additional banks or
financial institutions (collectively "Purchasing Banks") all or any portion of
its rights and obligations under this Agreement and the Related Documents
pursuant to a Commitment and Loan Transfer Supplement, executed by such
Purchasing Bank, such transferor Bank (and, in the case of a Purchasing Bank
that is not then a Bank, by the Borrower, the Issuing Banks and the Agents), and
delivered to the Administrative Agent for its acceptance and recording in the
Register hereinafter referred to as hereinafter provided); provided, however,
that (i) the Commitment purchased by any such Purchasing Bank which is not then
a Bank shall be equal to or greater than $5,000,000 unless such Purchasing Bank
is acquiring 100% of the Commitment of such transferor Bank, (ii) the transferor
Bank which has transferred part of its Commitment constituting less than such
Bank's full Commitment to any such Purchasing Bank which is not then a Bank
shall retain a Commitment, after giving effect to such sale, equal to or greater
than $5,000,000, and (iii) a transfer to any Purchasing Bank which is not then a
Bank shall be made only with the consent of the Borrower and the Agents and, in
the case of the transfer of a Bank's rights under this Agreement appurtenant to
the Revolving Credit Facility, the Issuing Banks and the Swingline Bank (which
in each case shall not be unreasonably withheld).  Upon such execution,
delivery, acceptance and recording, from and after the Transfer Effective Date
(determined pursuant to such Commitment and Loan Transfer Supplement), (x) the
Purchasing Bank thereunder shall be a party hereto and, to the extent provided
in such Commitment and Loan Transfer Supplement, have the rights and obligations
of a Bank hereunder with Commitments as set forth therein, and (y) the
transferor Bank thereunder shall, to the extent provided in such Commitment and
Loan Transfer Supplement, be released from its obligations under this Agreement
(and, in the case of a Commitment and Loan Transfer Supplement covering all or
the remaining portion of a transferor Bank's rights and obligations under this
Agreement, such transferor Bank shall cease to be a party hereto; provided,
however, that the provisions of this Agreement and the Related Documents shall
continue to inure to its benefit as to any actions taken or omitted by it while
it was a Bank).  Such Commitment and Loan Transfer Supplement shall be deemed to
amend this Agreement to the extent, and only to the extent, necessary to reflect
the addition of such Purchasing Bank and the resulting adjustment of Commitment

portion of the rights and obligations of such transferor Bank under this
Agreement and the Related Documents.  On or prior to the Transfer Effective
Date, the Borrower, at its own expense, shall execute and deliver to the
Administrative Agent in exchange for the surrendered Note or Notes of a
transferor Bank a new Note or Notes to the order of such Purchasing Bank in
amounts equal to the Commitment assumed by it pursuant to such Commitment and
Loan Transfer Supplement and, if the transferor Bank has retained a Commitment
hereunder, a new Note or Notes to the order of the transferor Bank in amounts
equal to the Commitment retained by it hereunder.  Such new Note or Notes shall
be dated the same dates as the Note or Notes surrendered and shall otherwise be
in the form of the Notes replaced thereby.  The Notes surrendered by the
transferor Bank shall be returned by the Administrative Agent to the Borrower
marked "exchanged".

          (d)  The Register.  The Administrative Agent shall maintain at its
               ------------                                                 
office a copy of each Commitment and Loan Transfer Supplement delivered to it
and a register (the "Register") for the recordation of the names and addresses
of the Banks and the Commitment of, and principal amount of the Obligations
owing to, each Bank from time to time.  The entries in the Register shall be
conclusive and binding for all purposes, in the absence of manifest error, and
the Borrower and the Bank Parties may treat each person whose name is recorded
in the Register as a Bank for all purposes of this Agreement.  The Register
shall be available for inspection by the Borrower or any Bank at any reasonable
time and from time to time upon reasonable prior notice.  Upon its receipt of a
Commitment and Loan Transfer Supplement executed by a transferor Bank and a
Purchasing Bank (and, in the case of a Purchasing Bank that is not then a Bank
or an affiliate thereof, by the Borrower and the Agents) together with the Note
or Notes subject to such transfer and payment by the Purchasing Bank to the
Administrative Agent of a registration and processing fee of $3,500 (which shall
be solely for the account of the Administrative Agent), and the Administrative
Agent shall (i) promptly accept such Commitment Transfer Supplement and (ii) on
the Transfer Effective Date determined pursuant thereto record the information
contained therein in the Register and give notice of such acceptance and
recordation to the other Bank Parties and the Borrower.

          (e)  Agreements of Transferor Bank and Purchasing Bank.  By executing
               -------------------------------------------------               
and delivering a Commitment and Loan Transfer Supplement, the transferor Bank
and the Purchasing Bank confirm to and agree with each other and the other
parties hereto as follows:  (i) other than as expressly provided in such
Commitment and Loan Transfer Supplement, the transferor Bank makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or with respect to the execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement or any of the Related
Documents or any other instrument or document furnished pursuant hereto and
thereto; (ii) the transferor Banks makes no representation or warranty and
assumes no responsibility with respect to the financial

                                     -150-

condition of the Credit Parties or the performance or observance by the Credit
Parties of any of its obligations under this Agreement or any of the Related
Documents or other instruments or documents furnished pursuant hereto or
thereto; (iii) the Purchasing Bank confirms that it has received a copy of this
Agreement and such other documents and information as it has deemed appropriate
to make its own credit analysis and decision to enter into such Commitment and
Loan Transfer Supplement; (iv) the Purchasing Bank will, independently and
without reliance upon the Administrative Agent, the transferor Bank or any other
Bank Party, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own decisions in taking or not
taking action under this Agreement and the Related Documents; (v) the Purchasing
Bank agrees that it will perform in accordance with their terms all of the
obligations which by the terms of this Agreement and the Related Documents are
required to be performed by it as a Bank; (vi) the Purchasing Bank agrees that
such Commitment and Loan Transfer Supplement is taken by it without recourse to
the transferor Bank.

          (f)  Financial and Other Information.  The Borrower hereby authorizes
               -------------------------------                                 
each Bank to disclose to any prospective Participant or Purchasing Bank (each a
"Transferee") or any potential Transferee any and all financial and other
information in such Bank's possession concerning the Borrower and its
Subsidiaries and Affiliates which has been or may be delivered to such Bank by
or on behalf of the Borrower pursuant to this Agreement or any of the Related
Documents or which has been or may be delivered to such Bank by or on behalf of
the Borrower in connection with such Bank's credit evaluation of the Borrower
and its Subsidiaries and Affiliates prior to becoming a party to this Agreement.
At the request of any Bank, the Borrower, at the Borrower's expense, shall
provide to each prospective Transferee the conformed copies of documents
referred to in Section 6(c) of the form of Transfer Supplement.

          (g)  Taxes.  Each Bank which is incorporated or organized under the
               -----                                                         
laws of any jurisdiction other than the United States or any state thereof
agrees that, on or prior to the date any payment is due to be made to it
hereunder or under any Related Document, it will furnish to the Borrower and the
Administrative Agent two valid, duly completed copies of (i) United States
Internal Revenue Service Form 4224 or 1001, or (ii) in the case of a Bank that
is not a "bank" within the meaning of Section 881(c)(3)(A) of the Code and
cannot deliver IRS Form 4224 or 1001, IRS Form W-8 and a certificate confirming
that such Bank is not a "Bank" for purposes of Section 881(c)(3)(A), or any
successor applicable form, as the case may be, certifying that such Bank is
entitled to a complete exemption from U.S. withholding tax with respect to (x)
in the case of clause (i) above, all payments, and (y) in the case of clause
(ii) above, payments of interest, to be made under this Agreement and the
Related Documents.  Each Bank which so delivers to the Borrower and the
Administrative Agent an Internal Revenue Service Form 1001, 4224 or W-8, or a
successor applicable form, agrees to deliver to the Borrower and the
Administrative Agent two further copies of the said
<PAGE>
 
                                     -151-

Internal Revenue Service Form 1001, 4224 or W-8 or a successor applicable form,
or other manner of certification, as the case may be, on or before the date that
any such form expires or becomes obsolete or otherwise is required to be
resubmitted as a condition to obtaining an exemption from withholding tax, or
after the occurrence of any event requiring a change in the most recent form
previously delivered by it, and such extensions or renewals thereof as may
reasonably be requested by the Borrower or the Administrative Agent, certifying
that such Bank is entitled to a complete exemption from or reduction in United
States withholding tax with respect to payments under this Agreement or any
Related Document, unless in any such cases an event (including any change in
law) has occurred prior to the date on which any such delivery would otherwise
be required which renders all such forms inapplicable or which would prevent
such Bank from duly completing and delivering any such form with respect to it
and such Bank advises the Borrower and the Administrative Agent that it is not
capable of delivering any such form or certificate, in which case such Bank
shall not be required or have any obligation to deliver any such form or
certificate. In addition, if at any time the Borrower believes that payments to
any Bank (foreign or domestic) may be subject to U.S. backup withholding tax,
such Bank shall, at the Borrower's reasonable request from time to time, if such
Bank is legally able to do so, provide the Borrower with evidence establishing
an exemption from U.S. backup withholding tax.

          (h)  Assignments to Federal Reserve Bank.  Any Bank may at any time
               -----------------------------------                           
assign all or any portion of its rights under this Agreement, including any
Obligation owing to it and any Note held by it, to a Federal Reserve Bank.  No
such assignment shall relieve the transferor Bank from any of its obligations
hereunder.

          10.13.  Replacement of Bank.
                  ------------------- 

          If at any time the all-in interest cost to the Borrower including any
increased costs imposed on the Borrower pursuant to Section 2.11(a) being paid
to any Bank becomes greater than 125% of the amount determined by multiplying
(a) the aggregate all-in interest cost to the Borrower (including such increased
costs) being paid to all of the Banks times (b) the Commitment Proportion of
such Bank, the Borrower may at its option replace such Bank with another
commercial lending institution by giving notice to the Bank Parties stating that
the Borrower wishes to replace such Bank and giving the name of the replacement
commercial lending institution, which replacement institution shall be
satisfactory to the remaining Bank Parties in their reasonable discretion.  Any
such replacement shall not be deemed to be a prepayment for any purpose hereof,
except that the Borrower shall pay to the Bank being replaced any payment
required to be made pursuant to Section 2.11(b) as if such replacement
constituted a prepayment.

          If a dispute or controversy arises under or in connection with this
Agreement, the parties agree first to try in good faith to settle the dispute or
controversy.  Any party may initiate the negotiation process by written notice
to the others, identifying the dispute or controversy and the desire for
negotiation.  If the parties have not resolved the dispute or controversy by
direct negotiations within thirty (30) days of such notice, any party may
initiate arbitration as herein provided.  All disputes or controversies arising
under or in connection with this Agreement which are not resolved by negotiation
shall be decided by arbitration before a single arbitrator selected by agreement
of the parties, and judgment upon the award or decision of the arbitrator may be
entered and enforced in any court of competent jurisdiction.  It is specifically
intended by the parties that any equitable relief granted by an arbitrator may
be enforced in any court of competent jurisdiction.  The forum of such
arbitration shall be in Pittsburgh, Pennsylvania to the exclusion of all other
jurisdictions.  In the event that the parties cannot agree upon the selection of
an arbitrator, the parties agree that the American Arbitration Association in
Pittsburgh, Pennsylvania will select the arbitrator.

          Arbitration Process.  The arbitrator shall decide the dispute or
          -------------------                                             
controversy in accordance with the following procedures:

          Within ten (10) days of the selection of an arbitrator, each party
shall submit to the arbitrator its written position (the "Initial Submission"),
                                                                               
provided that neither memorandum of position shall exceed 10 pages, double

spaced, plus such other documentary evidence as the parties deem necessary.

          Within ten (10) days of the delivery of the Initial Submission, each
party may submit to the arbitrator and the other party a reply memorandum (the
"Reply Submission"), provided that neither reply memorandum shall exceed 5
                     --------                                             
pages, double spaced.  In connection with the Reply Submission, neither of the
parties may submit (and the arbitrator may not accept) any additional
documentation (including affidavits).

          Within ten (10) days of the expiration of the period for the delivery
of the Reply Submission, the arbitrator, if he or she deems it necessary or
advisable, may call a hearing which may be by telephone conference (the
"Hearing").  At any Hearing, the arbitrator may ask representatives and counsel
for the parties' questions with respect to the issue to be decided and positions
of the parties.  In connection with the Hearing, neither of the parties may
offer (and the arbitrator may not accept) any testimony or additional
documentation (including affidavits).

          Within seven (7) days after the later to occur, if such is to occur,
of (a) the Hearing or (b) the Reply Submission, the arbitrator shall render his
or her position.

          The arbitrator shall promptly notify the parties in writing of the
decision, together with the amount of any dispute resolution costs arising with
respect thereto (the "Notice of Decision").  The Notice of Decision need not
contain an explanation of the decision or grounds therefor.

          The decision of the arbitrator shall be final, binding and not subject
to appeal.

          All dispute resolution costs, which shall include any fee for the
arbitrator for services rendered, shall be borne equally by the parties.  Each
party is to pay its own counsel fees and expenses.

  Each share of the former Series B Junior Convertible Preferred Stock was
assumed to have been converted into Non-Voting Common Stock. Common stock
equivalents include stock options granted to management, and stock warrants
granted to certain lenders prior to their exercise in 1995. Each stock option
awarded to management gives the holder the right to purchase an equivalent
amount of common stock at the listed exercise price and becomes exercisable in
increments of one third per year over a total vesting period of three years
from the date of grant. During 1995 all of the remaining stock warrants were
exercised in exchange for 2,399,850 shares of non-voting common stock for
$1.11 each, 61,650 of which were subsequently repurchased and retired. Net
income available to common stockholders prior to 1995 is net of dividends
accrued on the Series A Exchangeable Preferred Stock.

                            ARTICLES OF ASSOCIATION
                         PNC BANK, NATIONAL ASSOCIATION
                (Amended and Restated as of September 15, 1997)

          FIRST:  The title of this Association shall be "PNC Bank, National
Association."

          SECOND:  The main office of the Association shall be in the City of
Pittsburgh, Allegheny County, Pennsylvania.  The general business of the
Association shall be conducted at its main office and its branches.

          THIRD:  The Board of Directors of the Association shall consist of not
fewer than five (5) nor more than twenty-five (25) persons, the exact number of
Directors within such minimum and maximum limits to be fixed and determined from
time to time by a resolution of a majority of the full Board of Directors or by
resolution of the shareholders at any annual or special meeting thereof. Each
Director shall own such minimum qualifying equity interest in the ultimate
parent bank holding company of the Association as shall be required from time to
time by applicable law or regulation.  Unless otherwise provided by the laws of
the United States, any vacancy in the Board of Directors for any reason,
including an increase in the number thereof, may be filled by action of the
Board of Directors, within the limits then specified by law.

          A majority of the Board of Directors then in office shall be necessary
to constitute a quorum for the transaction of business at any meeting of the
Board.

          FOURTH:  The annual meeting of the shareholders for the election of
Directors and the transaction of whatever other business may be brought before
said meeting shall be held at the main office or such other place as the Board
of Directors may designate, on the day of each year specified therefor in the
By-Laws, but if no election is held on that day, it may be held on any
subsequent day according to the provisions of law; and all elections shall be
held according to such lawful regulations as may be prescribed by the Board of
Directors.  Any action which may be taken at a meeting of the shareholders of
the Association may be taken without a meeting if a consent in writing setting
forth the action so taken is signed by all the shareholders who would be
entitled to vote at a meeting for such purpose.
<PAGE>
 
          Terms of Directors, including Directors selected to fill vacancies,
shall expire at the regular meeting of shareholders at which Directors are
elected, unless a Director resigns or is removed from office prior to the date
of such meeting.

          Despite the expiration of a Director's term, the Director shall
continue to serve until his or her successor is elected and qualifies or until
there is a decrease in the number of Directors and his or her position is
eliminated.

          A Director may resign at any time by delivering written notice to the
Board of Directors, its Chairman, or to the Association's Secretary, which
resignation shall be effective when the notice is delivered unless the notice
specifies a later effective date.

          FIFTH: The amount of the authorized capital stock of the Association
shall be Two Hundred Eighteen Million Nine Hundred Eighteen Thousand, Five
Hundred and Seventy Dollars ($218,918,570), divided into 6,735,956 shares of
common stock of the par value of Thirty-Two Dollars and Fifty Cents ($32.50)
each, but said capital stock may be increased or decreased from time to time in
accordance with the provisions of the laws of the United States.

          No holder of shares of the capital stock of any class of the
Association shall have any preemptive or preferential right of subscription to
any shares of any class of stock of the Association, whether now or hereafter
authorized, or to any obligations convertible into stock of the Association,
issued or sold, nor any right of subscription to any thereof other than such, if
any, as the Board of Directors, in its discretion, may from time to time
determine and at such price as the Board of Directors may from time to time fix.

          The Association, at any time and from time to time, may authorize and
issue debt obligations, whether or not subordinated, without the approval of the
shareholders.

          SIXTH: The Board of Directors shall appoint one of its members
President of the Association who shall be Chairman of the Board; but the Board
of Directors may appoint a Director, in lieu of the President, to be Chairman of
the Board, who shall perform such duties as may be designated by the Board of
Directors.  The Board of Directors shall have the power to appoint one or more
Vice Presidents of various ranks; to appoint a Cashier, a Secretary, and such
other officers and employees

                                      -6-
<PAGE>
 
as may be required or deemed advisable to transact the business of the
Association; to fix the salaries to be paid such officers and employees; to
dismiss at its pleasure such officers and employees and to appoint others to
take their place.

          The business and affairs of the Association shall be managed by or
under the direction of the Board of Directors.  The Board of Directors shall
have the power to define the duties of officers and employees of the Association
and to require adequate bonds from them for the faithful performance of their
duties; to make all By-Laws and adopt all resolutions that may be lawful for the
general regulation of the business of the Association and the management of its
affairs, including but not limited to, the manner of election or appointment of
Directors, officers, or employees and the appointment of judges of election, and
generally to do and perform all acts that may be lawful for a Board of Directors
to do and perform.  Notwithstanding any provision of this or any other Article,
the Board of Directors may delegate to the management of the Association such
authorities and powers as the Board of Directors deems advisable from time to
time, to the fullest extent permitted by applicable laws, regulations, and safe
and sound banking practices.

          SEVENTH: (a) Subject to any prohibitions or limitations set forth in
sections (b) and (g) of this Article or the Association's By-Laws, the
Association may indemnify or reimburse any Director, officer, or employee for,
or advance amounts in payment of, any expenses actually and reasonably incurred
in any threatened, pending or completed action or proceeding, whether civil,
criminal, administrative, or investigative, to which such individual was or is a
party or a potential party by reason of his or her performance of official
duties on behalf of or at the request of the Association.  Such duties shall
specifically include, but not be limited to, service performed at the request of
the Association as a representative of a domestic or foreign corporation for
profit or not-for-profit, partnership, joint venture, trust or other enterprise.
For purposes of this Article, "expenses" shall include, but not be limited to,
attorneys' fees and costs, judgments, fines, taxes, penalties, and amounts paid
or to be paid in settlement.

          (b)   Notwithstanding any provision of this Article or the
Association's By-Laws, the following prohibitions and limitations shall apply:
(i) No indemnification

                                      -7-
<PAGE>
 
shall be made in any case where the act or failure to act giving rise to the
claim for indemnification is determined by a court of competent jurisdiction to
have constituted willful misconduct or recklessness; (ii) No indemnification
shall be made for any expenses incurred in an administrative proceeding or civil
action instituted by a federal banking agency which proceeding or action results
in a final order or settlement pursuant to which the Director, officer or
employee is assessed a civil money penalty; removed from office or prohibited
from participating in the conduct of the Association's affairs; or is required
to cease and desist from or take any affirmative action described in Section
8(b) of the Federal Deposit Insurance Act with respect to the Association; (iii)
The Association may advance expenses to a Director, officer or employee in
connection with an action or proceeding under 12 U.S.C. (S)(S)164 or 1818 only
if the Board of Directors has first made such determinations and findings and
otherwise satisfied such procedural requirements, if any, as may be specified by
rule, regulation, advice, or guidance issued by a federal banking agency having
jurisdiction over the Association; (iv) Any advance of expenses must be subject
to a written and legally binding agreement which specifies, at a minimum, that
reimbursement to the Association of expenses advanced (including expenses
already paid) shall be required if and to the extent that: (a) the expenses are
not covered by any insurance policy or fidelity bond purchased by the
Association or its holding company; (b) the Board of Directors finds that the
Director, officer, or employee willfully misrepresented factors relevant to the
Board's decision to advance expenses; or (c) for any other reason the expenses
advanced subsequently become prohibited indemnification payments, as defined in
12 C.F.R. (S)359.1(1); and (v) No indemnification shall be made with respect to
amounts provided for by any compromise settlement unless such settlement shall
have been approved by a court of competent jurisdiction, or the holders of
record of a majority of the outstanding shares of the Association, or the Board
of Directors, acting by vote of Directors not parties to the same or
substantially the same action, or proceeding, constituting a majority of the
whole number of Directors.

          (c)  The Association may provide for the payment of reasonable
premiums for insurance policies or fidelity bonds covering the payment of
expenses and the liabilities

                                      -8-
<PAGE>
 
of its Directors, officers, and employees, provided that no such insurance or
fidelity bond coverage may be purchased for a final order assessing any judgment
or civil money penalty against such individuals in an administrative proceeding
or civil action commenced by a federal banking agency.

          (d)  Any amendment or repeal of this Article, or the adoption of any
other provision of the Articles of Association or By-Laws which has the effect
of increasing the liability of the Association's Directors, officers, and
employees shall operate prospectively only and shall not affect any action
taken, or any failure to act, prior to the adoption of such amendment, repeal or
other provisions.

          (e)  The Board of Directors may adopt By-Law provisions consistent
with this Article and may limit the classes of individuals to whom this Article
shall apply.  In the event of any inconsistency or conflict between this Article
and such By-Law provisions, this Article shall control; provided, that a By-Law
provision limiting the classes of individuals to whom this Article shall apply
shall not be deemed to be such an inconsistency or conflict.

          (f)  The rights of indemnification or reimbursement provided for in
this Article shall not be exclusive of other rights, if any, to which such
Directors, officers, or employees, or their personal representatives, may be
entitled as a matter of Pennsylvania law.

          (g)  Notwithstanding any other provision of this Article or the
Association's By-Laws, the Association shall not make or agree to make any
prohibited indemnification payment, as defined in 12 C.F.R. (S)359.1(1).

          EIGHTH:  The Board of Directors shall have the power, without the
approval of the shareholders, to change the location of the main office to any
other place within the limits of the City of Pittsburgh, Allegheny County,
Pennsylvania, and to establish or change the location of any branch or branches
of the Association subject to the approval of the Comptroller of the Currency.

          NINTH:  The corporate existence of the Association shall continue
until terminated in accordance with the laws of the United States.

          TENTH:  The Board of Directors of the Association, or any three (3) or
more shareholders owning, in the aggregate, not less than ten (10%) percent of
the stock of the Association, may call

                                      -9-
<PAGE>
 
a special meeting of the shareholders at any time.  Unless otherwise provided by
the laws of the United States or duly waived, a notice of the time, place, and
purpose of every annual and every special meeting of the shareholders shall be
given by first-class mail, postage prepaid, mailed at least ten (10) days prior
to the date of such meeting to each shareholder of record at his address as
shown upon the books of the Association.

          ELEVENTH:  These Articles of Association may be amended at any regular
or special meeting of the shareholders by the affirmative vote of the holders of
a majority of the stock of this Association, unless the vote of the holders of a
greater amount of stock is required by law, and in that case by the vote of the
holders of such greater amount.

          TWELFTH:  Honorary or advisory directors, without voting power or
power of final decision in matters concerning the business of the Association,
may be appointed by resolution of a majority of the full Board of Directors, or
by resolution of shareholders at any annual or special meeting. Honorary or
advisory directors shall not be counted to determine the number of Directors of
the Association or the presence of a quorum in connection with any Board action
and shall not be required to own a qualifying equity interest. Honorary or
advisory directors may be appointed to one or more advisory boards of directors
of the Association, to serve upon such terms and conditions as may be specified
by the Board of Directors, or the Association's By-Laws.

  DELIVERY OF THIS INSTRUMENT TO AN ADDRESS OTHER THAN AS SET FORTH ABOVE, OR

NOT CONSTITUTE A VALID DELIVERY.
 
  The undersigned acknowledges that he or she has received and reviewed the
Prospectus, dated      , 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

   DUE 2007 OF KOPPERS INDUSTRIES, INC., WHICH HAVE NOT BEEN SO REGISTERED.
 
  1. DELIVERY OF THIS LETTER AND NOTES; GUARANTEED DELIVERY PROCEDURES. This
letter is to be completed by Holders of Old Notes either if certificates are
to be forwarded herewith or if tenders are to be made pursuant to the
procedures for delivery by book-entry transfer set forth in "The Exchange
Offer--Book-Entry Transfer" section of the Prospectus and an Agent's Message
is not delivered. Certificates for all physically tendered Old Notes, or a
Book-Entry Confirmation, as the case may be, as well as a properly completed
and duly executed Letter (or manually signed facsimile hereof) and any other
documents required by this Letter, must be received by the Exchange Agent at
the address set forth herein on or prior to the Expiration Date, or the
tendering holder must comply with the guaranteed delivery procedures set forth
below. Old Notes tendered hereby must be in denominations of a principal
amount of $1,000 and any integral multiple thereof. 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 that such Participant has
received and agrees to be bound by this Letter and that the Company may
enforce this Letter against such Participant.
 
  Holders whose certificates for Old Notes are not immediately available or
who cannot deliver their certificates and all other required documents to the
Exchange Agent on or prior to the Expiration Date, or who cannot complete the
procedure for book-entry transfer on a timely basis, may tender their Old
Notes pursuant to the guaranteed delivery procedures set forth in "The
Exchange Offer--Guaranteed Delivery Procedures" section of the Prospectus.
Pursuant to such procedures, (i) such tender must be 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 must receive from such Eligible
Institution a properly completed and duly executed Letter (or a facsimile
thereof or Agent's Message in lieu 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 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
Letter 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 all
other documents required by this Letter, are deposited by the Eligible
Institution within three NYSE trading days after the date of execution of the
Notice of Guaranteed Delivery.
 
  The method of delivery of this Letter, the Old Notes and all other required
documents is at the election and risk of the tendering Holders, but the
delivery will be deemed made only when actually received or confirmed by the
Exchange Agent. If Old Notes are sent by mail, it is suggested that the
mailing be by registered mail, properly insured, with return receipt
requested, and made sufficiently in advance of the Expiration Date to permit
delivery to the Exchange Agent prior to 5:00 p.m. New York City time, on the
Expiration Date.
 
  See "The Exchange Offer" section of the Prospectus.

the person named must also be indicated. Holders tendering Old Notes by book-

  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

  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

                           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.
