PROSPECTUS     
 
                       NAVISTAR INTERNATIONAL CORPORATION
 
 OFFER TO EXCHANGE ITS SERIES B 7% SENIOR NOTES DUE 2003 FOR ANY AND ALL OF ITS
  OUTSTANDING 7% SENIOR NOTES DUE 2003 AND TO EXCHANGE ITS SERIES B 8% SENIOR
    SUBORDINATED NOTES DUE 2008 FOR ANY AND ALL OF ITS OUTSTANDING 8% SENIOR
                          SUBORDINATED NOTES DUE 2008.
   
THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON APRIL 6,
1998, UNLESS EXTENDED.     
 
  Navistar International Corporation, a Delaware corporation ( the "NIC"),
hereby offers (the "Exchange Offer"), upon the terms and conditions set forth
in this Prospectus (the "Prospectus") and the accompanying Letter of
Transmittal (the "Letter of Transmittal"), to exchange: (i) $1,000 principal
amount of its Series B 7% Senior Notes due 2003 (the "Senior Exchange Notes"),
which will have been registered under the Securities Act of 1933, as amended
(the "Securities Act"), pursuant to a Registration Statement of which this
Prospectus is a part, for each $1,000 principal amount of its outstanding 7%
Senior Notes due 2003 (the "Old Senior Notes"), of which $100,000,000 principal
amount is outstanding; and (ii) $1,000 principal amount of its Series B 8%
Senior Subordinated Notes due 2008 (the "Senior Subordinated Exchange Notes"
and, together with the Senior Exchange Notes, the "Exchange Notes"), which will
have been registered under the Securities Act pursuant to a Registration
Statement of which this Prospectus is a part, for each $1,000 principal amount
of its outstanding 8% Senior Subordinated Notes due 2008 (the "Old Senior
Subordinated Notes" and, together with the Old Senior Notes, the "Old Notes"),
of which $250,000,000 principal amount is outstanding. The form and terms of
the Exchange Notes are the same as the form and term of the Old Notes (which
they replace) except that (i) the Exchange Notes will bear a Series B
designation and a different CUSIP Number from the Old Notes, (ii) will have
been registered under the Securities Act and, therefore, will not bear legends
restricting its transfer thereof, and (iii) will not contain certain provisions
relating to an increase in the interest rate which were included in the terms
of the Old Notes in certain circumstances relating to the timing of the
Exchange Offer. The Senior Exchange Notes will evidence the same debt as the
Old Senior Notes (which they replace) and will be issued under and be entitled
to the benefits of the Indenture governing the Old Senior Notes dated February
4, 1998 (the "Senior Notes Indenture") among NIC and Harris Trust and Savings
Bank, as trustee (the "Senior Notes Trustee"). The Senior Subordinated Exchange
Notes will evidence the same debt as the Old Senior Subordinated Notes (which
they replace) and will be issued under and entitled to the benefits of the
Indenture governing the Old Senior Subordinated Notes dated February 4, 1998
(the "Senior Subordinated Notes Indenture" and, together with the Senior Notes
Indenture, the "Indentures") among NIC and the Harris Trust and Savings Bank,
as trustee (the "Senior Subordinated Notes Trustee" and together with the
Senior Notes Trustee, the "Trustees" and individually each a "Trustee"). See
"The Exchange Offer" and "Description of the Notes."
 
  The Old Senior Notes and Senior Exchange Notes are sometimes collectively
referred to herein as the "Senior Notes," the Old Senior Subordinated Notes and
the Senior Subordinated Exchange Notes are sometimes collectively referred to
herein as the "Senior Subordinated Notes" and the Senior Notes and Senior
Subordinated Notes are sometimes collectively referred to herein as the
"Notes."
   
  NIC 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 April 6, 1998, unless
extended by NIC in its sole discretion (the "Expiration Date"). In order to
extend the Exchange Offer, NIC will notify the Exchange Agent of any extension
by oral or writte     n notice and will mail to the registered holders,
including the holders who previously tendered their Old
 
                                        (Cover page continued on following page)
 
                                  ----------
 
  SEE "RISK FACTORS" BEGINNING ON PAGE 20 FOR A DESCRIPTION OF CERTAIN RISKS TO
BE CONSIDERED BY HOLDERS WHO TENDER THEIR OLD NOTES IN THE EXCHANGE OFFER.
 
THESE  SECURITIES HAVE NOT BEEN APPROVED  OR DISAPPROVED BY THE SECURITIES  AND
 EXCHANGE  COMMISSION   OR  ANY  STATE  SECURITIES  COMMISSION  NOR   HAS  THE
  COMMISSION OR ANY  STATE SECURITIES COMMISSION PASSED UPON  THE ACCURACY OR
   ADEQUACY OF  THIS PROSPECTUS.  ANY  REPRESENTATION TO  THE CONTRARY  IS A
    CRIMINAL OFFENSE.

Notes, an announcement thereof, each prior to 9:00 a.m. New York City time, on
the next business day after the previously scheduled Expiration Date. Tenders
of Old Notes may be withdrawn at any time prior to 5:00 p.m. on the Expiration
Date. The Exchange Offer is subject to certain customary conditions. See "The
Exchange Offer."
 
  The Old Notes were sold by NIC on February 4, 1998 to the respective Initial
Purchasers (as defined) in transactions not registered under the Securities
Act in reliance upon an exemption under the Securities Act (the "Initial
Offerings"). The Initial Purchasers subsequently placed the Old Notes with (i)
qualified institutional buyers in reliance upon Rule 144A under the Securities
Act and (ii) qualified buyers outside the United States in reliance upon
Regulation S under the Securities Act. Accordingly, the Old Notes may not be
reoffered, resold or otherwise transferred in the United States unless
registered under the Securities Act or unless an applicable exemption from the
registration requirements of the Securities Act is available. The Exchange
Notes are being offered hereunder in order to satisfy the obligations of NIC
under the Registration Rights Agreements entered into by NIC and the
respective Initial Purchasers in connection with the Initial Offerings (the
"Registration Rights Agreements"). See "The Exchange Offer."
 
  The Senior Notes are not redeemable at the option of NIC prior to maturity.
The Senior Subordinated Notes are redeemable, in whole or in part, at the
option of NIC at any time on or after February 1, 2003 at the redemption
prices set forth herein, together with accrued and unpaid interest, if any, to
the date of redemption. In addition, prior to February 1, 2001, NIC may, at
its option, redeem up to 35% of the original principal amount of the Senior
Subordinated Notes at 108.0% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the applicable redemption date, with the net cash
proceeds of one or more Public Equity Offerings (as defined). Upon the
occurrence of a Change of Control (as defined), each holder of Notes may
require NIC to purchase all or a portion of such holder's Notes at a purchase
price equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest, if any, to the date of purchase.
 
  The Senior Notes are unsecured senior obligations of NIC, ranking pari passu
in right of payment with all existing and future unsubordinated Indebtedness
of NIC, and rank senior in right of payment to all existing and future
subordinated Indebtedness (as defined) of NIC, including the Senior
Subordinated Notes. The Senior Subordinated Notes are unsecured senior
subordinated obligations of NIC, ranking subordinate in right of payment to
all existing and future Senior Indebtedness (as defined) of NIC, including the
Senior Notes, and ranking pari passu in right of payment with all existing and
future senior subordinated Indebtedness of NIC and senior in right of payment
in all existing and future subordinated Indebtedness of NIC. As of October 31,
1997, after giving pro forma effect to the Initial Offerings and the
application of the net proceeds therefrom, NIC would have had $350 million of
total Indebtedness outstanding, of which $250 million would have been
subordinated Indebtedness and $100 million would have ranked senior in right
of payment of the Senior Subordinated Notes. In addition, the Senior Notes and
Senior Subordinated Notes are effectively subordinated to all existing and
future liabilities of the subsidiaries of NIC. As of October 31, 1997, after
giving pro forma effect to the Initial Offerings and the application of the
net proceeds therefrom, the amount of liabilities of such subsidiaries
(including trade payables) would have been approximately $4,431 million. See
"Description of the Notes."
 
  Based upon an interpretation by the staff of the Securities and Exchange
Commission (the "Commission") set forth in certain no-action letters issued to
third parties, NIC believes that the Exchange Notes issued pursuant to the
Exchange Offer in exchange for the Old Notes may be offered for resale, resold
and otherwise transferred by any holder thereof (other than any such holder
that is an "affiliate" of NIC within the meaning of Rule 405 under the
Securities Act) without compliance with the registration and prospectus
delivery requirements of the Securities Act, provided that such Exchange 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 the
distribution of such Exchange Notes. See "The Exchange Offer--Resale of the
Exchange Notes." Holders of Old Notes wishing to accept the Exchange Offer
must represent to NIC, as required by the Registration Rights Agreements, that
such conditions have been met. Each broker-dealer (a "Participating Broker-
Dealer") that receives Exchange Notes for its own account pursuant to the
Exchange Offer must acknowledge that it will deliver a prospectus in
 
                                       2
<PAGE>
 
(Continued from cover page)
connection with any resale of such Exchange Notes. The Letter of Transmittal
states that by so acknowledging and by delivering a prospectus, a
participating 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
Participating Broker-Dealer in connection with resales of Exchange Notes
received 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. NIC has agreed that, for a period of 180 days after the
Expiration Date, it will make this Prospectus available to any Participating
Broker-Dealer for use in connection with any such resale (provided that the
Company receive notice from such Participating Broker-Dealer within 30 days
after the consummation of the Exchange Offer of his status as a Participating
Broker-Dealer). See "Plan of Distribution."
 
  NIC will not receive any proceeds from the Exchange Offer. NIC has agreed to
bear the expenses of the Exchange Offer which are estimated to be
approximately $300,000. No underwriter is being used in connection with the
Exchange Offer.
 
  There has not previously been any public market for the Old Notes or the
Exchange Notes. NIC does not intend to list the Exchange Notes on any
securities exchange or to seek approval for quotation through any automated
quotation system. There can be no assurance that an active market for the
Exchange Notes will develop. See "Risk Factors--Absence of a Public Market
Could Adversely Affect the Value of Exchange Notes." Moreover, 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.
 
  The Exchange Notes will be available initially only in book-entry form.
Except as described under "Description of the Notes--Book-Entry; Delivery and
Form," NIC expects that the Exchange Notes issued pursuant to the Exchange
Offer will be represented by a Global Note (as defined), which will be
deposited with, or on behalf of, The Depository Trust Company (the
"Depository") and registered in its name or in the name of Cede & Co., its
nominee. Beneficial interests in the Global Note representing the Exchange
Notes will be shown on, and transfers thereof will be effected through,
records maintained by the Depository and its participants. After the initial
issuance of the Global Note, Notes in certificated form will be issued in
exchange for the Global Note only under limited circumstances as set forth in
the Indenture. See "Description of the Notes--Book-Entry; Delivery and Form."
                 
              The date of this Prospectus is March 5, 1998.

such engines in the 160-300 horsepower range. In fiscal 1997, the Company's
manufacturing operations had revenues of $6,147 million and EBITDA (as defined)
of $268 million.
 
  Navistar markets its truck products and service parts through the largest
retail organization in North America specializing in medium and heavy trucks,
which at October 31, 1997, included 992 dealers and retail outlets. Service and
customer support are also supplied at these locations. In the United States and
Canada, Navistar operates seven regional parts distribution centers which allow
24-hour availability and same day shipment of parts most frequently requested
by dealers and customers. To better serve the growing Mexican market, the
Company established a Mexican distribution network in 1996 and began
construction of a new truck assembly facility located near Monterrey, Mexico in
1997. Through Navistar Financial Corporation ("NFC"), the Company provides
wholesale, retail and, to a lesser extent, lease financing in the United States
for sales of new and used trucks sold by the Company and Navistar's dealers.
NFC also finances wholesale accounts and selected retail accounts receivable of
the Company.
 
COMPETITIVE STRENGTHS
 
  The Company believes its key competitive strengths include the following:
 
  Leading Market Position. The Company has been the leader in the combined
market share for Class 5 through 8 trucks, including school buses, in the
United States and Canada in each of its last 17 fiscal years. In fiscal 1997,
the Company's combined market share of the Class 5 through 8 truck market was
28.6%, a 1.1 percentage point increase in market share from the previous year.
For each of the last five fiscal years, the Company has been the leader in the
medium truck and school bus markets. In addition, the Company believes that it
is the largest supplier of replacement parts to the heavy and medium truck and
bus aftermarkets.
 
  Commitment to Customer Satisfaction. In order to achieve high customer
satisfaction, the Company maintains the largest retail organization in North
America specializing in medium and heavy trucks. In addition, the Company
operates seven regional parts distribution centers in the United States and
Canada, enabling it to offer 24-hour availability and same day shipment of the
parts most frequently requested by customers. In 1997,

Navistar was ranked number one for the third consecutive year by the annual
American Truck Dealers ("ATD") Attitude Survey, which evaluates OEMs on quality
and performance issues related to products, parts, policies and service.
 
  Largest Supplier of Mid-Range Diesel Engines. The Company is the leading
supplier of mid-range diesel engines in the 160-300 horsepower range and is
currently the exclusive supplier of diesel engines to The Ford Motor Company
("Ford") for use in its diesel-powered light trucks and vans. On October 29,
1997, the Company finalized its agreement with Ford to supply newly-designed,
advanced technology engines through the year 2012 for use in Ford's F-series
pickup trucks and Econoline vans. This 10-year agreement is scheduled to become
effective beginning with model year 2003 and will replace the Company's current
agreement with Ford, which will expire after model year 2002. The Company has
been supplying diesel engines to Ford since 1982.
 
TRUCK STRATEGY
 
  In fiscal 1997, the Company continued to implement its five-point truck
strategy, which the Company adopted in fiscal 1996 in order to improve
operating performance and increase profitability. Specifically, this strategy
is designed to enable Transportation's truck division to achieve its part in
Navistar's goal of generating an average 17.5% after tax return on equity over
a business cycle. The principal components of this strategy as well as recent
achievements in its implementation include:
 
  . Reduce Product Complexity. The Company believes that it can increase
    manufacturing efficiency and improve product quality by reducing the
    complexity of its product offerings. Historically, thousands of options
    and a separate chassis design were offered for each truck model
    manufactured by Transportation, which led to significant manufacturing
    inefficiencies. In 1996, Transportation introduced a new ordering program
    known as Diamond Spec(TM) for its premium conventional heavy duty trucks.
    Under this program, Transportation rationalized the number of possible
    option combinations by developing pre-packaged option groups which are
    arranged under 11 categories (i.e., engine, chassis, electrical system)
    based upon the most popular preferences of its customers. Transportation
    also combined the chassis for three models offered in this premium
    conventional product category into one chassis. In 1997, Transportation
    expanded its Diamond Spec(TM) ordering system and completed a successful
    pilot program in 11 key markets for its medium trucks. This
    standardization of option and chassis groups is expected to lead to
    significant operating cost savings from increased manufacturing
    efficiency and to better pricing for purchased components. In addition,
    Transportation believes that this program will result in an overall
    improvement in product quality and shorter and more reliable delivery
    times.
 
  . Focus Manufacturing Facilities. The Company believes that it can achieve
    significant improvements in manufacturing efficiency by focusing each of
    its principal truck manufacturing facilities on producing a single type
    of truck model. In order to sharpen the Company's focus on serving its
    customers and markets, the Company recently announced a reorganization of
    its truck group into six distinct businesses. The new organization will
    consist of four vehicle centers--heavy truck, severe service truck,
    medium truck and school bus, and two business centers--parts and
    international. In fiscal 1996, Transportation transferred the production
    of its stripped chassis from its Springfield, Ohio facility to its
    Conway, Arkansas facility, in order to achieve efficiencies in the
    production of medium duty trucks. Similarly, the Company established a
    joint venture, SST Truck Company, which will focus on the production of
    the highly-complex Paystar(R) severe service trucks, thereby permitting
    Transportation's Chatham, Ontario facility to concentrate on
    manufacturing premium conventional heavy duty trucks.
 
  . Emphasize Product Development. The Company believes that each of its
    current truck models equals or exceeds those of its competitors in terms
    of satisfying its customers' needs. Nevertheless, the Company intends to
    continue to enhance and expand its current product offerings in an effort
    to provide trucks that better satisfy its customers' changing demands. In
    fiscal 1997, Navistar's Board of Directors approved funding for its next
    generation truck program (the "NGT Program"). Pursuant to the NGT
    Program, the

   Company expects to make $350 million in capital expenditures and spend
   $300 million in development costs over the next six years to develop and
   manufacture a full line of world-class medium trucks, school buses and
   regular conventional heavy trucks. These new models will offer enhanced
   driver comfort, operating efficiency, overall appearance, quality and
   performance. The design and development phases of the NGT Program are
   currently underway and the Company expects the first new vehicles to be
   available in mid-2001, with additional new vehicles to follow
   approximately every six months through 2003. In 1997, Transportation also
   introduced the International(R) 9100 conventional truck to replace the
   International(R) 8200 conventional truck and made significant improvements
   to its premium conventional models. Further model improvements are
   expected to be introduced for Transportation's premium conventional heavy
   duty truck models in fiscal 1998.
 
  . Expand International Operations. The Company believes that there are
    significant opportunities to increase sales of both trucks and engines in
    Mexico and in other selected export markets. In 1997, the Company
    captured approximately 11.5% of the Mexican truck market after
    establishing a dealer network and a parts distribution center and
    arranging for production at a contract manufacturer in 1996. The
    Company's dealer network in Mexico was expanded from 23 to 38 locations
    in 1997. The Company is currently constructing an assembly facility
    located near Monterrey, Mexico. This medium duty and heavy duty truck
    facility is anticipated to cost approximately $167 million and to begin
    production by late 1998. Its capacity will be 65 units per shift. The
    Company believes that its Mexican operations will enable it to expand
    into other Latin American countries, particularly as a result of the
    favorable and cost effective trade agreements between Mexico and other
    Latin American countries. The Company has also recently established a
    presence in Brazil by forming a Brazilian subsidiary and signing an
    agreement with a Brazilian equipment manufacturer to assemble commercial
    trucks. The Company expects that production of its trucks in Brazil will
    begin in late 1998.
 
  . Establish Competitive Wage, Benefit and Productivity Levels.
    Transportation expects to achieve significant productivity gains as a
    result of favorable changes in job classifications, work rules and
    training. In August 1997, Transportation's collective bargaining
    agreement with the United Automobile, Aerospace & Agricultural Implement
    Workers of America (the "UAW") was extended through October 1, 2002. This
    contract contains significant changes from the prior agreement, enabling
    the Company to better focus its assembly plants, simplify current product
    lines, invest in new product development and
   achieve more competitive wage, benefit and productivity levels. This new
   agreement enabled the Company to reinstate its NGT Program and continue to
   implement its five-point truck strategy. In 1996, Transportation signed a
   new three-year collective bargaining agreement with the Canadian Auto
   Workers (the "CAW").
 
  The Company's principal executive office is located at 455 North Cityfront
Plaza Drive, Chicago, Illinois 60611, and its telephone number is (312) 836-
2000.

Untendered Old Notes............ Following the consummation of the
                                 Exchange Offer, holders of Old Notes
                                 eligible to participate but who do not
                                 tender their Old Notes will not have any

                                 Accordingly, the liquidity of the market
                                 for such Old Notes could be adversely

                                 of the Exchange Offer. The Company has
                                 agreed to maintain the effectiveness of
                                 the Shelf Registration Statement for,

Special Procedures for           Any beneficial owner whose Old Notes are
 Beneficial Owners.............. registered in the name of a broker,
                                 dealer, commercial bank, trust company or
                                 other nominee and who wishes to tender
                                 should contact such registered holder
                                 promptly and instruct such registered
                                 holder to tender on such beneficial
                                 owner's behalf. If such beneficial owner
                                 wishes to tender on such owner's own
                                 behalf, such owner must, prior to

                                 holder. The transfer of registered
                                 ownership may take considerable time. The
                                 Company will keep the Exchange Offer open
                                 for not less than 20 business days in

                                 outstanding, of which $100 million would

Change of Control............... Upon the occurrence of a Change of
                                 Control, each holder of Senior Notes and
                                 the Senior Subordinated Notes may require
                                 NIC to purchase all or a portion of such
                                 holder's Senior Notes or Senior
                                 Subordinated Notes, as the case may be, at
                                 a purchase price equal to 101% of the
                                 aggregate principal amount thereof, plus
                                 accrued and unpaid interest, if any, to
                                 the date of purchase. See "Description of
                                 the Notes--Change of Control."
 
Certain Covenants............... The Indentures contain certain covenants
                                 that, among other things, limit the
                                 ability of NIC and its Restricted
                                 Subsidiaries (as defined) to incur
                                 additional indebtedness, pay dividends or
                                 make certain other restricted payments,
                                 engage in transactions with affiliates,
                                 incur liens and engage in asset sales. The
                                 Indentures also restrict the ability of
                                 NIC and its Restricted Subsidiaries to
                                 consolidate or merge with, or transfer all
                                 or substantially all of their assets to,
                                 another person. However, these limitations
                                 are subject to a number of important
                                 qualifications and exceptions. See
                                 "Description of the Notes--Certain
                                 Covenants."
 
                                 After the Senior Notes have been assigned
                                 an Investment Grade (as defined) rating,
                                 NIC and its Restricted Subsidiaries will
                                 no longer be subject to the provisions of
                                 certain of the covenants listed above. See
                                 "Description of the Notes--Certain
                                 Covenants--Relating Only to the Senior
                                 Notes--Application of Fall Away
                                 Covenants."

  Unexercised employee stock options to purchase shares of Navistar Common
  Stock were not included in the diluted shares outstanding when the options'
  exercise prices were greater than the average market price of Navistar
  Common Stock during the respective periods. Additionally, the diluted
  calculation excludes the effects of the conversion of the Series G
  Preferred Stock as such conversion would produce anti-dilutive results. The
  dilutive effect of options outstanding and the conversion of Series D
  Preferred Stock were not included in 1993 diluted shares as such inclusion
  would produce anti-dilutive results. Basic and diluted loss of discontinued
  operations per common share in 1994 was $0.27. Basic and diluted loss from
  the cumulative effect of changes in accounting policy per common share in
  1993 was $6.56. In January of 1998, the Company repurchased approximately
  3.2 million shares of its Class B Common Stock from the Supplemental Trust.
  For the fiscal year ended October 31, 1997, after giving pro forma effect
  to the Initial Offerings and the application of the net proceeds therefrom,
  as if each had occurred as of the beginning of fiscal 1997 basic and
  diluted income of continuing operations per common share and basic and
  diluted net income per common share would have each been $1.93 and $1.92,
  respectively.

(1) Gives pro forma effect to the Initial Offerings and the application of the
    net proceeds therefrom as if each had occurred as of the beginning of
    fiscal 1997. Pro forma adjustments include: (i) a net increase in interest
    expense of $20 million; (ii) a corresponding reduction in cost of products
    sold and other expense of an aggregate $6 million due to lower profit-
    sharing expense; (iii) a corresponding decrease in income tax expense of $5
    million; and (iv) the elimination of dividends paid on the Series G
    Convertible Cumulative Preferred Stock of $29 million. The pro forma
    information does not purport to represent what the Company's results of
    operations actually would have been if the Initial Offerings had actually
    occurred as of such dates or what such results will be for any future
    periods.
(2) The Company contributed approximately 25.6 million of shares of its Class B
    Common Stock valued at $509 million to the Supplemental Trust in 1993.
(3) The 1994 loss of discontinued operations resulted from a $20 million after
    tax charge for environmental liabilities at production facilities of two
    formerly owned businesses, Wisconsin Steel and Solar Turbine, Inc.
(4) In the third quarter of 1993, the Company adopted SFAS 106 and SFAS 109,
    retroactive to November 1, 1992.
(5) Gives effect to the sale of the Old Notes in the Initial Offerings and the
    application of the net proceeds therefrom as if each had occurred on
    October 31, 1997. See "Capitalization."
(6) EBITDA represents income from manufacturing operations before the
    cumulative effect of changes in accounting policy, interest expense, taxes
    on income and depreciation and amortization expense. The Company believes
    EBITDA provides additional information for measuring its ability to
    generate funds for liquidity and capital requirements. This information is
    presented as a supplement to the other data provided because it provides
    information which the Company believes is useful for additional analysis.
    EBITDA should not be considered in isolation or as a substitute for net
    income, cash flows from operating activities and other consolidated
    operations or cash flow statement data prepared in accordance with
    generally accepted accounting principles or as a measure of the Company's
    profitability or liquidity.
(7) For the purpose of this ratio, total debt was calculated in the pro forma
    column by giving effect to the sale of the Old Notes in the Initial
    Offerings and the application of the net proceeds therefrom as if each had
    occurred on October 31, 1997.

                                 RISK FACTORS
 
  Holders of the Old Notes should carefully consider the following factors in
addition to the other information contained in this Prospectus. This
Prospectus contains forward-looking statements that involve risks and
uncertainties. Actual results could differ materially from those discussed
herein. Factors that could cause or contribute to such differences include,
but are not limited to, those identified below as well as those discussed
elsewhere in this Prospectus.
 
MARKET AND GENERAL ECONOMIC CONDITIONS
 
  Navistar's ability to be profitable depends in part on the varying
conditions in the medium and heavy truck, mid-range diesel engine and service
parts markets. See "Business." The truck markets in which the Company competes
are subject to considerable volatility. Such markets move in response to
cycles in the overall business environment and are particularly sensitive to
the industrial sector, which generates a significant portion of the freight
tonnage hauled. Truck and engine demand also depend on general economic
conditions, interest rate levels and fuel costs.
 
COMPETITION
 
  The North American truck market, in which Navistar competes, is highly
competitive. Navistar's major domestic competitors include PACCAR, Ford and
General Motors, as well as foreign-controlled domestic manufacturers, such as
Freightliner, Mack and Volvo GM. In addition, well-capitalized manufacturers
from Japan (Hino, Isuzu, Nissan, Mitsubishi) are attempting to increase their
North American sales levels. The intensity of this competition, which is
expected to continue, results in price discounting and margin pressures
throughout the industry and adversely affects Navistar's ability to increase
or maintain vehicle prices. Many of Navistar's competitors have greater
financial resources, which may place Navistar at a competitive disadvantage in
responding to substantial industry changes, such as changes in governmental
regulations that require major additional capital expenditures. In addition,
certain of Navistar's competitors may have lower overall labor costs.
 
FUTURE CAPITAL REQUIREMENTS
 
  Navistar has announced plans for approximately $350 million in capital
spending over the next six years for the NGT Program. Capital expenditures for
fiscal 1998 are expected to be approximately $370 million, of which $25
million is to be spent for the NGT Program. Additional capital expenditures
are planned for the completion of the truck assembly facility in Mexico,
increased manufacturing capacity at the Indianapolis engine plant,
commencement of truck operations in Brazil and improvements to existing
facilities and products. Navistar's investment in the NGT Program will also
include $300 million in development expense over the next six years, of which
approximately $50 million is planned for 1998.
 
  The Company will be required to make substantial cash expenditures over the
next several years to implement its NGT Program and to meet its other capital
expenditure and development objectives. Historically, Navistar has relied on
cash balances and cash provided by operations to meet its funding
requirements. The amount of cash generated by Navistar's business varies with
industry volumes in the medium and heavy truck markets. No assurance can be
given that Navistar will have the cash balances necessary to implement its NGT
Program and to meet its other capital requirements or that financing will be
available or, if available, that it will be available on satisfactory terms.
The future availability of financing will depend on many factors, including
Navistar's earnings, credit ratings, the outlook for truck industry demand and
the capital resources of financial institutions. If adequate funds are not
available, the Company may be required to cut back or discontinue the NGT
Program or other product development or capital improvement programs. See
"Management's Discussion and Analysis of Results of Operations and Financial
Condition--Liquidity and Capital Resources" and
"--Business Environment."
 
  From and after July 1, 1998, the Settlement Agreement in respect of
Navistar's postretirement healthcare and life insurance benefits (the
"Settlement Agreement") gives the Supplemental Trust established thereunder
 
                                      20
<PAGE>
 
the exclusive right, subject to certain limited exceptions, to conduct public
offerings of Common Stock for a period of 5 years (the "Window Period"),
subject to earlier termination at such time as the Supplemental Trust has
received net proceeds of $500 million from qualifying sales of Common Stock.
During this period, Navistar will be prohibited from conducting public
offerings of equity securities for working capital or other purposes unless
the Supplemental Committee (as defined) under the Supplemental Trust otherwise
consents. To date, the Company believes that the Supplemental Trust has
received approximately $78 million in net proceeds from qualifying sales of
Common Stock. See "--Potential Influence of Supplemental Trust."
 
RELIANCE ON MAJOR CUSTOMER
 
  Ford accounted for approximately 14% of the Company's revenues during fiscal
1997 and fiscal 1996 and approximately 12% for fiscal 1995. Although the
Company has contracts with Ford that continue through 2012, such contracts
provide for supplying Ford's requirements for particular models, rather than
for manufacturing a specific quantity of products. The loss of Ford as a
customer or a significant decrease in demand for the models or a group of
related models that utilize the Company's products could have a material
adverse effect on the Company.
 
HOLDING COMPANY STRUCTURE
 
  NIC, the issuer of the Notes, is a holding company with no significant
business operations other than (i) holding the capital stock of Transportation
and Navistar International Corporation Mexico S.A. de C.V. ("Navimex"), other
subsidiaries and joint venture interests and (ii) advancing funds to, and
receiving funds from, its direct and indirect subsidiaries. In repaying its
indebtedness, including the Notes, NIC must rely on dividends and other
payments made to it by Transportation and its other direct and indirect
subsidiaries. In addition, the Indentures governing the Notes will allow the
Company the ability to make substantial investments (including, without
limitation, contributions of assets) in joint ventures.
 
  The holders of the Notes have no direct claims against the assets of NIC's
subsidiaries. The ability of NIC's subsidiaries to make payments to NIC will
be affected by the obligations of such subsidiaries to their creditors. Claims
of holders of indebtedness of NIC, including the Notes, against the cash flow
and assets of NIC's subsidiaries will be effectively subordinated to claims of
such creditors. In addition, the rights of the holders of the Notes to
participate in the assets of any subsidiary of NIC upon such subsidiary's
liquidation or recapitalization will be subject to the prior claims of such
subsidiary's creditors. As of October 31, 1997, after giving pro forma effect
to the Initial Offerings and the application of the net proceeds therefrom,
the direct and indirect subsidiaries of NIC would have had approximately
$4,431 million of liabilities (including trade payables). The ability of NIC's
subsidiaries to make payments to NIC will also be subject to, among other
things, applicable state corporate laws and contractual restrictions. State
corporate laws applicable to NIC's subsidiaries generally prohibit the payment
of dividends by any given subsidiary unless such subsidiary has capital
surplus or net profits in the current or immediately preceding year. In
addition, the payment of dividends by NFC is limited by the terms of several
of its financings. See "Description of Other Financing Arrangements."
 
SUBORDINATION OF THE SENIOR SUBORDINATED NOTES
 
  The payment on the principal of, premium, if any, and interest on the Senior
Subordinated Notes will be subordinate in right of payment to the prior
payment in full of all Senior Indebtedness of NIC, including the Senior Notes,
whether outstanding at the date of the indenture in respect of the Senior
Subordinated Notes or thereafter incurred. As of October 31, 1997, after
giving pro forma effect to the Initial Offerings and the application of the
net proceeds therefrom, NIC would have had $100 million in Senior Indebtedness
outstanding, all of which would rank senior to the Senior Subordinated Notes,
and no indebtedness which would be subordinated to the Senior Subordinated
Notes. Additional Senior Indebtedness can be incurred by NIC from time to
time, subject to certain restrictions. In the event of a default in the
payment or prepayment of the principal of, premium, if any, or interest on any
Senior Indebtedness of NIC, NIC is prohibited from making any payment with
respect to the principal of, premium, if any, or interest on the Senior
Subordinated Notes unless and until
 
                                      21
<PAGE>
 
such default has been cured or waived or all Senior Indebtedness of NIC has
been discharged or paid in full. In addition, the Senior Subordinated Notes
will be effectively subordinated to all existing and future liabilities of the
subsidiaries of NIC. As of October 31, 1997, after giving pro forma effect to
the Initial Offerings and the application of the net proceeds therefrom, the
amount of such liabilities (including trade payables) would have been
approximately $4,431 million. See "--Holding Company Structure."
 
  In addition, upon any payment or distribution of NIC's assets to its
creditors upon any dissolution, winding-up, liquidation, reorganization,
bankruptcy, insolvency, receivership or other proceedings relating to NIC,
whether voluntary or involuntary, the holders of Senior Indebtedness of NIC
will be entitled to receive payment in full of all amounts due thereon before
the holders of the Senior Subordinated Notes will be entitled to receive any
payment with respect to the principal of, premium, if any, or interest on the
Senior Subordinated Notes. By reason of such subordination, in the event of
the insolvency of NIC, holders of the Senior Subordinated Notes may receive
less, ratably, than holders of Senior Indebtedness of NIC and other creditors
of NIC, or may recover nothing. See "Description of the Notes--Subordination
of Senior Subordinated Notes; Ranking."
 
IMPACT OF GOVERNMENT REGULATION
 
  Truck and engine manufacturers continue to face increasing governmental
regulation of their products, especially in the areas of environment and
safety. As a diesel engine manufacturer, Navistar has incurred research and
tooling costs to redesign its engine product lines to meet the United States
Environmental Protection Agency ("U.S. EPA") and California Air Resources
Board ("CARB") emission standards effective for the 1998 model year. In
addition, Navistar expects to continue to incur research, design and tooling
costs to: (i) achieve further reductions in ozone-causing exhaust emissions by
2004 in accordance with the voluntary agreement entered into by Navistar,
along with other engine manufacturers, with the U.S. EPA and CARB and (ii)
satisfy the 1998 Clean Fuel Fleet Vehicle requirements and California's
emission standards in 2002 for engines used in medium-size vehicles. Navistar
expects that its diesel engines will be able to meet all of these standards
within the required time frames.
 
  Truck manufacturers are also subject to various noise standards imposed by
federal, state and local regulations, and to the National Traffic and Motor
Vehicle Safety Act and Federal Motor Vehicle Safety Standards promulgated by
the National Highway Traffic Safety Administration. Navistar believes it is in
compliance with such standards.
 
  Complying with such laws and regulations has added and will continue to add
to the cost of Navistar's products, and increases the capital-intensive nature
of Navistar's business. If the present level of price competition continues,
it may become increasingly difficult for manufacturers of engines and trucks
to recover these costs and, accordingly, lower margins may result. See
"Business--Impact of Government Regulation."
 
PENSION AND POSTRETIREMENT HEALTH CARE OBLIGATIONS
 
  Navistar has significant underfunded pension obligations. At October 31,
1997, the accumulated benefit obligation of Navistar's underfunded pension
plans was approximately $445 million, compared to $607 million at October 31,
1996. In November 1997, Navistar contributed $100 million to the hourly
pension plan. Navistar's long-term objective is to fund its entire accumulated
pension benefit obligation over the next 5 to 8 years with funds that are
principally generated by operations.
 
  In the event Navistar's pension plans were terminated for any reason and
plan assets were insufficient to meet guaranteed liabilities, the Pension
Benefit Guaranty Corporation ("PBGC") may have a right to take over these
plans as their administrator and trustee. In this event, the actual present
value of guaranteed pension liabilities may be determined in a manner
different from that used by Navistar to determine its unfunded vested pension
liability. Subject to certain limitations, the PBGC would have a claim against
Navistar to the extent that plan assets were not sufficient to meet the
actuarial present value of guaranteed liabilities.
 
  In addition to providing pension benefits, Navistar provides health care and
life insurance for a majority of its retired employees and their spouses and
certain dependents and will provide retiree health care and life
 
                                      22
<PAGE>
 
insurance benefits for most of its existing employees hired before July 1,
1993. In 1993, a trust was established to partially fund this post-retirement
health care liability (the "Base Trust"). In November 1997, Navistar
contributed $200 million to the Base Trust satisfying the balance of its $500
million prefunding obligation, although Navistar will remain obligated to make
future contributions to the Base Trust on a pay-as-you-go basis. These
benefits are provided as part of the Settlement Agreement.
 
POTENTIAL INFLUENCE OF SUPPLEMENTAL TRUST
 
  In July 1993, Navistar restructured its postretirement health care and life
insurance benefits pursuant to the Settlement Agreement that resolved
litigation between Navistar and a class of its employees, retirees and
collective bargaining organizations, including the UAW, as lead class
plaintiff. The Settlement Agreement provides, among other things, that
Navistar establish a Supplemental Benefit Trust (the "Supplemental Trust") for
the purpose of funding certain retiree and health benefits under a
Supplemental Benefit Program. The Supplemental Trust currently holds
approximately 19.9 million shares of Navistar's non-voting Class B Common
Stock. On July 1, 1998, the non-voting Class B Common Stock held by the
Supplemental Trust will convert into voting Common Stock, which is the same
class of stock held by Navistar's other shareowners. Based upon the 49.2
million shares of Common Stock currently outstanding, the Supplemental Trust
would hold approximately 29% of Navistar's voting stock upon conversion. As a
result of such stock ownership, it is likely that the Supplemental Trust will
be able to have a significant influence over those matters submitted to a vote
of Navistar's shareowners, including the election of directors and approval of
certain significant corporate transactions, following such conversion. A
committee of five members acts as administrator of the Supplemental Benefit
Program (the "Supplemental Committee") and as such has the power to direct the
voting of the Common Stock held by the Supplemental Trust. Two of the members
of the Supplemental Committee are designees of the UAW, one is a retired
management employee and two are independent from either Navistar or the UAW.
In addition, the Settlement Agreement provides for the addition of three seats
to Navistar's Board of Directors, one of which is elected by the UAW and two
of which are elected by the Supplemental Committee on behalf of the
Supplemental Trust. Navistar's Board of Directors is currently comprised of 14
persons.
 
RISK OF LOSS OF TAX BENEFITS
 
  If, as a result of any transaction involving Navistar's equity securities,
an "ownership change" occurs for federal income tax purposes, the Company's
ability to use its substantial net operating losses (the "NOLs") to offset
taxable income, and thereby reduce Navistar's tax liability, would be severely
limited, requiring an adjustment to Navistar's deferred tax asset reflected in
its Statement of Financial Condition. The Settlement Agreement requires that
Navistar not sell or acquire Common Stock or other securities or take other
actions if to do so would put Navistar at risk of an "ownership change" or
would limit the ability of the Supplemental Trust to sell on or after July 1,
1998 Common Stock up to an amount equal to $500 million less proceeds from
prior sales of Common Stock (which amount is currently approximately $372
million) without putting Navistar's NOLs at risk. The Company believes, based
on the information currently available to it, that the redemption of the
Series G Convertible Cumulative Preferred Stock should not, by itself, put the
Company at risk of an "ownership change" or restrict the ability of the
Supplemental Trust to sell up to an additional $372 million of stock. See
"Management's Discussion and Analysis of Results of Operations and Financial
Condition--Income Taxes" for a discussion of the Company's NOLs.
 
  As part of the Settlement Agreement, a provision (the "Prohibited Transfer
Provision") was added to NIC's Certificate of Incorporation to protect against
certain transfers of equity securities which could cause an "ownership
change." Although the Prohibited Transfer Provision is intended to prevent
transfers which could cause an "ownership change," Navistar may not be able to
prevent every transaction that could cause an "ownership change." By its
terms, the Prohibited Transfer Provision will expire on June 30, 2001.
 
ABSENCE OF A PUBLIC MARKET COULD ADVERSELY AFFECT THE VALUE OF EXCHANGE NOTES
 
  The Old Notes were issued to, and the Company believes are currently owned
by, a relatively small number of beneficial owners. Prior to the Exchange
Offer, there has not been any public market for the Old Notes. The
 
                                      23
<PAGE>
 
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 Exchange Notes by holders who are entitled to participate in
this 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 Exchange
Notes will constitute a new issue of securities with no established trading
market. The Company does not intend to list the Exchange Notes on any national
securities exchange or seek the admission thereof to trading in the National
Association of Securities Dealers Automated Quotation System. The Initial
Purchasers have advised the Company that they currently intend to make a
market in the Exchange Notes, but they are not obligated to do so and may
discontinue such market making at any time. In addition, such market making
activity will be subject to the limits imposed by the Securities Act and the
Exchange Act and may be limited during the Exchange Offer and the pendency of
the Shelf Registration Statement. Accordingly, no assurance can be given that
an active public or other market will develop for the Exchange Notes or as to
the liquidity of the trading market for the Exchange Notes. If a trading
market does not develop or is not maintained, holders of the Exchange Notes
may experience difficulty in reselling the Exchange Notes or may be unable to
sell them at all. If a market for the Exchange Notes develops, any such market
may be discontinued at any time.
 
  If a public trading market develops for the Exchange Notes, future trading
prices of such securities will depend on many factors including, among other
things, prevailing interest rates, the Company's results of operations and
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 Exchange Notes may trade at a discount from
their principal amount.
 
FAILURE TO FOLLOW EXCHANGE OFFER PROCEDURES COULD ADVERSELY AFFECT HOLDERS
 
  Issuance of the Exchange 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 or
Agent's Message and all other required documents. Therefore, holders of the
Old Notes desiring to tender such Old Notes in exchange for Exchange 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 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 Exchange 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 transaction. Each broker-dealer that receives
Exchange 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 Exchange 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."

                                USE OF PROCEEDS
 
  This Exchange Offer is intended to satisfy certain of the Company's
obligations under the Purchase Agreements and the Registration Rights
Agreements. The Company will not receive any cash proceeds from the issuance
of the Exchange Notes offered hereby. In consideration for issuing the
Exchange Notes contemplated in this Prospectus, the Company will receive Old
Notes in like principal amount, the form and terms of which are the same as
the form and terms of the Exchange Notes (which replace the Old Notes), except
as otherwise described herein.
 
  The net proceeds from the sale of the Old Senior Notes (after deducting the
discounts to the Initial Purchasers and the expenses in connection with such
offering) were approximately $98 million. The Company has used or expects to
use such net proceeds as follows: (i) approximately $47 million will be used
to repay the 9% Sinking Fund Debentures due June 15, 2004 of Transportation
(the "9% Debentures"), including all accrued and unpaid interest thereon; and
(ii) approximately $27 million has been used to repay the 8% Secured Note due
August 15, 2002 of Transportation (the "8% Note"), including all accrued and
unpaid interest thereon. Any remaining proceeds will be for general corporate
purposes, including working capital.
 
  The net proceeds from the sale of the Old Senior Subordinated Notes (after
deducting discounts to the Initial Purchasers and the expenses in connection
with such offering) were approximately $244 million, which will be used to
redeem NIC's Series G Convertible Cumulative Preferred Stock (the "Series G
Preferred") and to pay accumulated and unpaid dividends thereon.
 
  The Company intends to repay the 9% Debentures and redeem the Series G
Preferred as soon as practical after completion of the Initial Offerings.
Pending such uses outlined above, the Company will invest such net proceeds
from the Initial Offerings in short-term, investment grade, interest-bearing
securities.

                                CAPITALIZATION
 
  The following table sets forth the historical capitalization of the Company
as of October 31, 1997 and as adjusted to give effect to the sale of the Old
Notes in the Initial Offerings and the application of the net proceeds
therefrom. The Old Notes surrendered in exchange for Exchange Notes will be
retired and canceled and cannot be reissued. Accordingly, issuance of the
Exchange Notes will not result in any increase or decrease in the indebtedness
of the Company. As such, no effect has been given to the Exchange Offer in the
following capitalization table. See "Use of Proceeds."

(1) In November 1997, Navistar contributed $100 million to the hourly pension
    plan and $200 million to the Base Trust. These contributions were funded
    from existing cash balances.
(2) In January 1998, the Company repurchased approximately 3.2 million shares
    of its Class B Common Stock from the Supplemental Trust. The purchase
    price of approximately $83 million was funded from existing cash balances.
(3) In November 1997, the Company's Mexican subsidiary established a $125
    million credit facility to be used to fund the development of the
    Company's Mexican operations. As of December 31, 1997, an aggregate of $35
    million of borrowings was outstanding under such facility. All of such
    subsidiary's indebtedness under such facility is guaranteed on a senior
    basis by NIC.

(2) The Company contributed approximately 25.6 million shares of its Class B
    Common Stock valued at $513 million to the Supplemental Trust in 1993.
(3) The 1994 loss of discontinued operations resulted from a $20 million after

    expense amortization and the portion of rental expense deemed
    representative of an interest factor by the sum of interest expense, debt
    expense amortization and the portion of rental expense deemed
    representative of the interest factor. Earnings were insufficient to cover
    fixed charges by approximately $441 million in fiscal 1993. For the fiscal
    year ended October 31, 1997, after giving pro forma effect to the Initial
    Offerings and the application of the net proceeds therefrom, as if each
    had occurred as of the beginning of fiscal 1997, the Company's ratio of

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS
                     OF OPERATIONS AND FINANCIAL CONDITION
 
  The following discussion and analysis should be read in conjunction with the
Company's Financial Statements and notes thereto included elsewhere in this
Prospectus. Certain statements under this caption constitute "forward-looking
statements" under Section 27A of the Securities Act and involve risks and
uncertainties. The Company's actual results may differ significantly from the
results discussed in such forward-looking statements. Factors that might cause
such a difference include, but are not limited to, those discussed under the
captions "Risk Factors" and "Business Environment."
 
GENERAL
 
  NIC is a holding company and its principal operating subsidiary is
Transportation. The Company's manufacturing operations are engaged in the
manufacture and marketing of Class 5 through 8 trucks, including school buses,
mid-range diesel engines and service parts primarily in the United States and
Canada. These products are also sold to distributors in selected export
markets. The financial services operations of the Company provide wholesale,
retail and lease financing, and commercial physical damage and liability
insurance coverage to the Company's dealers and retail customers and to the
general public through an independent insurance agency system.
 
  The discussion and analysis reviews the operating and financial results, and
liquidity and capital resources of manufacturing operations and financial
services operations. Manufacturing operations include the financial results of
the financial services operations included on a one-line basis under the
equity method of accounting. Financial services operations include NFC, its
domestic insurance subsidiary as well as the Company's foreign finance and
insurance companies. See Note 1 to the Financial Statements.
 
BUSINESS ENVIRONMENT
 
  Sales of Class 5 through 8 trucks are cyclical, with demand affected by such
economic factors as industrial production, construction, demand for consumer
durable goods, interest rates and the earnings and cash flow of dealers and
customers. Reflecting the stability of the general economy, demand for new
trucks remained strong during 1997. An improvement in the number of new truck
orders has increased the Company's order backlog to 45,300 units at October
31, 1997 from 20,900 units at October 31, 1996. Retail deliveries in 1998
continue to be highly dependent on the rate at which new truck orders are
received. The Company will evaluate order receipts and backlog throughout the
year and will balance production with demand as appropriate.
 
  The Company currently projects 1998 United States and Canadian Class 8 heavy
truck demand to be 195,000 units, a slight decrease from 1997. Class 5, 6 and
7 medium truck demand, excluding school buses, is forecast at 116,000 units,
slightly lower than in 1997. Demand for school buses is expected to decrease
8% in 1998 to 30,500 units. Mid-range diesel engine shipments by the Company
to original equipment manufacturers in 1998 are expected to be 215,700 units,
17% higher than in 1997. The Company's service parts sales are projected to
grow 9% to approximately $875 million.
 
  The Supplemental Trust, which was created in 1993 for the benefit of the
Company's current and future retirees and administered by a five person trust
committee, owned all of the outstanding Class B Common Stock at October 31,
1997, which represented approximately one-third of the Company's outstanding
Common Stock. The Class B Common Stock has restricted voting rights and
transfer provisions but, on July 1, 1998, will convert into Common Stock with
full voting rights and no transfer restrictions.
 
  During August 1997, the Company's current master contract with the UAW was
extended through October 1, 2002. This contract allows the Company to focus
its assembly plants, simplify current product lines, invest in new product
development, and achieve more competitive wage, benefit and productivity
levels.
 
                                      29

  During 1997, the Company entered into a ten-year agreement, effective with
model year 2003, to supply newly designed, advanced technology engines through
the year 2012 to Ford for use in its diesel-powered light trucks and vans. The
Company's current engine agreement with Ford was extended through model year
2002.
 
  The Company is currently considering an internal corporate reorganization,
whereby, among other things, Transportation's engine and service parts
operations and NFC would become direct subsidiaries of NIC.
 
RESULTS OF OPERATIONS
 
  The Company reported net income of $150 million for 1997, or $1.65 per
common share, reflecting higher sales of manufactured products. Net income was
$65 million, or $0.49 per common share, in 1996 and $164 million, or $1.83 per
common share, in 1995. Net income in 1996 included a one-time $35 million
pretax charge for costs related to the termination of the NGT Program. In
August 1997, the Company and the UAW reached agreement on a master contract
extension that enabled the Company to reinstate this program. The remaining
accrual for the 1996 charge at the time of the announcement was not material.
 
  The Company's manufacturing operations reported income before income taxes
of $164 million in 1997 compared with pretax income of $22 million in 1996 and
$200 million in 1995. The increase in 1997 reflects higher sales of trucks and
diesel engines as well as the effects of improved pricing and various cost
improvement initiatives. The decrease in 1996 from 1995 reflects a decline in
demand for trucks as well as the charge for termination of the Company's NGT
Program.
 
  The Company's financial services operations had income before income taxes
of $78 million, $83 million and $62 million in 1997, 1996 and 1995,
respectively.
 
  NFC's pretax income in 1997 was $75 million, a 7% decrease from $81 million
in 1996. The change is primarily a result of lower income on sales of retail
receivables and a decline in wholesale financing activity. The reduced gains
on sales resulted from lower margins on retail notes reflecting higher market
interest rates prior to the date of sale. NFC's pretax income increased $22
million in 1996 from the $59 million reported in 1995 primarily due to higher
income on sales of retail notes and an increased volume of wholesale
financing.
 
  Earnings from the foreign finance and insurance subsidiaries were $3
million, $2 million and $3 million in 1997, 1996 and 1995, respectively.
 
  SALES AND REVENUES. Industry retail sales of Class 5 through 8 trucks
totaled 347,400 units in 1997, a 2% increase from the 341,200 units sold in
1996, but 9% lower than the 380,600 units sold in 1995. Class 8 heavy truck
sales totaled 196,800 units, comparable to the 195,400 units sold in 1996 but
a decrease of 14% from the 228,800 units sold in 1995. Industry sales of Class
5, 6 and 7 medium trucks, including school buses, totaled 150,600 units in
1997, a 3% increase from 1996 when 145,800 units were sold, and comparable to
the 151,800 units sold in 1995. Industry sales of school buses, which
accounted for 22% of the medium truck market, increased slightly from 1996 to
33,200 units.
 
  Sales and revenues of $6,371 million in 1997 were 11% higher than the $5,754
million reported in 1996 and comparable to the $6,342 million reported in
1995. Sales of trucks, mid-range diesel engines and service parts totaled
$6,147 million in 1997, 12% above the $5,508 million reported for 1996 and
comparable to the $6,125 million reported in 1995.
 
  The Company maintained its position as sales leader in the combined United
States and Canadian Class 5 through 8 truck market in 1997 with a 28.6% market
share, an increase from the 27.5% share in 1996 and the 26.7% share in 1995.
(Sources: American Automobile Manufacturer's Association, the United States
Motor Vehicle Manufacturer's Association and R. L. Polk & Company.) In 1997,
the Company's share of the Class 8 heavy truck market increased to 18.6% from
17.1% in 1996 and 18.4% in 1995.
 
  Shipments of mid-range diesel engines by the Company to other OEMs during
1997 were a record 184,000 units, a 13% increase from 1996 and a 19%
improvement over 1995. Higher shipments to Ford to meet consumer demand for
the light trucks and vans which use this engine was the primary reason for the
increase.
 
                                      30
<PAGE>
 
  Service parts sales of $806 million in 1997 increased from the $760 million
reported in 1996 and were 10% higher than the $730 million reported in 1995 as
a result of dealer and national account volume growth.
 
  Finance and insurance revenue for 1997 was $174 million, 12% lower than the
$197 million reported in 1996 primarily as a result of a decline in wholesale
financing activity. Revenues from financial services operations increased 18%
between 1996 and 1995 primarily as a result of higher income on sales of
retail notes.
 
  COSTS AND EXPENSES. Manufacturing gross margin was 14.2% of sales in 1997,
compared with 12.5% in 1996 and 13.8% in 1995. The increase in gross margin is
primarily due to lower production costs and improved pricing offset by a
provision for employee profit sharing. Factors which contributed to the change
in gross margin between 1996 and 1995 included lower sales volumes, more
competitive pricing and the costs of terminating the NGT Program.
 
  Engineering and research expense was $124 million in 1997, $129 million in
1996 and $113 million in 1995, reflecting continuing investment in new truck
and engine products as well as improvements to existing products.
 
  Marketing and administrative expense was $365 million in 1997 compared with
$319 million in 1996 and $307 million in 1995. The change between 1997 and
1996 is the result of higher sales and distribution costs, and an increase in
the provision for payment to employees as provided by the Company's
performance incentive programs. The $12 million increase in the expense
between 1996 and 1995 reflects investment in the implementation of the
Company's strategy to reduce costs and complexity in its manufacturing
processes.
 
  Interest expense decreased to $74 million in 1997 from $83 million in 1996
and $87 million in 1995. The decreases in 1997 and 1996 were the result of
lower wholesale note funding requirements and declining interest rates.
 
  Finance service charges on sold receivables were $23 million in 1997, 4%
lower than in 1996 and 21% lower than in 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Cash flow is generated from the manufacture and sale of trucks, mid-range
diesel engines and service parts as well as product financing and insurance
coverage provided to Transportation's dealers and retail customers by the
financial services operations.
 
  Historically, funds to finance Transportation's products are obtained from a
combination of commercial paper, short- and long-term bank borrowings, medium-
and long-term debt issues, sales of finance receivables and equity capital.
NFC's current debt ratings have made bank borrowings and sales of finance
receivables the most economic sources of cash. Insurance operations are funded
through internal operations.
 
  Total cash, cash equivalents and marketable securities of the Company
amounted to $965 million at October 31, 1997, $881 million at October 31, 1996
and $1,040 million at October 31, 1995.
 
  Cash provided by operations during 1997 totaled $380 million, primarily from
net income of $150 million, $82 million of noncash deferred income taxes, $59
million of other noncash items, principally depreciation, and a net change in
operating assets and liabilities of $89 million. Income tax expense for 1997
was $92 million, of which $10 million was cash payments to federal and certain
state and local governments, while the remaining $82 million of federal and
other taxes reduced the deferred tax asset.
 
  The net change in operating assets and liabilities of $89 million includes a
$195 million increase in receivables, reflecting continued strong demand for
the Company's products, offset by a $288 million increase in accounts payable
as a result of increased production in the fourth quarter.
 
 
                                      31
<PAGE>
 
  Investment programs included a net decrease in marketable securities, as
sales of securities exceeded purchases by $45 million. During 1997, the
purchase of $970 million of retail notes and lease receivables was funded with
$958 million in proceeds from the sale of receivables and principal
collections of $94 million. Other investment activities used $42 million for
an increase in property and equipment leased to others and $172 million to
fund capital expenditures. Capital expenditures included $82 million for
construction of a truck assembly facility in Mexico, $42 million to increase
mid-range diesel engine capacity and additional funds for truck product
improvements.
 
  Financing activities used cash to pay $29 million in dividends on the Series
G Preferred shares, $46 million for principal payments on long-term debt, and
$285 million to reduce notes and debt outstanding under the bank revolving
credit facility and asset-backed and other commercial paper programs offset by
an increase of $209 million in long-term debt.
 
  During 1997 and 1996, NFC supplied 94% of the wholesale financing of new
trucks sold to Transportation's dealers compared with 93% in 1995. NFC's share
of the retail financing of new trucks sold in the United States decreased to
13% in 1997 from 16% in 1996 and 14% in 1995 due to the highly competitive
commercial financing market.
 
  The sale of finance receivables is a significant source of funding for the
financial services operations. During 1997, 1996 and 1995, NFC sold $987
million, $985 million and $740 million, respectively, of retail notes through
Navistar Financial Retail Receivables Corporation ("NFRRC"), a wholly owned
subsidiary. The net proceeds from these sales were used for general working
capital purposes. In November 1997, NFC sold an additional $500 million of
retail notes through NFRRC.
 
  NFRRC has filed registration statements with the SEC which provide for the
issuance of up to $5,000 million of asset-backed securities. At October 31,
1997, the remaining shelf registration available to NFRRC for issuance of
asset-backed securities was $1,473 million. See Note 8 to the Financial
Statements.
 
  NFC has a $925 million contractually committed bank revolving credit
facility and a $400 million asset-backed commercial paper program supported by
a bank liquidity facility which mature in March 2001. NFC also utilizes a $600
million revolving wholesale note trust that provides for the continuous sale
of eligible wholesale notes on a daily basis. The trust is comprised of two
$100 million tranches of investor certificates maturing serially from 1998 to
1999, and two $200 million tranches maturing in 2003 and 2004. At October 31,
1997, the remaining shelf registration available for issuance of investor
certificates was $200 million.
 
  At October 31, 1997, available funding under NFC's amended and restated
credit facility (the "Credit Agreement") and the asset-backed commercial paper
facility (the "ABCP Program") was $532 million and $14 million, respectively,
of which $141 million was used to back short-term debt at October 31, 1997.
 
  The Company finances capital expenditures principally through internally
generated cash. Capital leasing is used to fund selected projects based on
economic and operating factors. The Company had outstanding capital
commitments of $137 million at October 31, 1997 primarily for increased
manufacturing capacity at the Indianapolis engine plant and construction of a
truck assembly facility in Mexico.
 
  The Company has announced plans for approximately $350 million in capital
spending over the next six years for the NGT Program. Capital expenditures for
1998 are expected to be approximately double the current year's level.
Approximately $25 million is to be spent in 1998 for the NGT Program.
Additional capital expenditures are planned for the completion of the truck
assembly facility in Mexico, increased manufacturing capacity at the
Indianapolis engine plant, commencement of truck operations in Brazil and
improvements to existing facilities and products. The Company's investment in
the NGT Program will also include $300 million in development expense over the
next six years, of which approximately $50 million is planned for 1998.
 
  In November 1997, the Company contributed $200 million to the Retiree Health
Care Base Plan Trust and contributed $100 million to the hourly pension plan.

  NFC's maximum exposure under all receivable sale recourse provisions at
October 31, 1997 was $246 million; however, management believes that the
allowance for credit losses on sold receivables is adequate.
 
  At October 31, 1997, the Canadian operating subsidiary was contingently
liable for retail customers' contracts and leases financed by a third party.
The Company is subject to maximum recourse of $261 million on retail contracts
and $13 million on retail leases. In addition, as of October 31, 1997, the
Company is contingently liable for approximately $49 million for various
guarantees and buyback programs; however, based on historical loss trends, the
Company's exposure is not considered material.
 
  The Canadian operating subsidiary, NFC and certain other subsidiaries
included in financial services operations are parties to agreements which
result in the restriction of amounts which can be distributed to
Transportation in the form of dividends, loans or advances. At October 31,
1997, the maximum amount of dividends which were available for distribution
under the most restrictive covenants was $62 million.
 
  The Company and Transportation are obligated under certain agreements with
public and private lenders of NFC to maintain the subsidiary's income before
interest expense and income taxes at not less than 125% of its total interest
expense. No income maintenance payments were required for the three years
ended October 31, 1997. See "Business--Certain Arrangements with NFC."
 
  During November 1997, the Company arranged financing for $125 million of
funds denominated in U.S. dollars and Mexican pesos to be used for development
of the Company's Mexican operations.
 
  Management continues to evaluate current and forecasted cash flow as a basis
for financing operating requirements, capital expenditures and anticipated
payments of preferred dividends. Management believes that collections on the
outstanding receivables portfolios as well as funds available from various
funding sources will permit the financial services operations to meet the
financing requirements of the Company's dealers and customers.
 
ENVIRONMENTAL MATTERS
 
  In the fourth quarter of 1994, Transportation recorded a $20 million charge,
net of $13 million of income taxes, as a loss of discontinued operations
related to environmental liabilities at production facilities of two formerly
owned businesses, Wisconsin Steel and Solar Turbine, Inc. Included in the
charge was an anticipated $11 million payment to the Economic Development
Administration, a division of the U.S. Department of Commerce, in settlement
of commercial and environmental disputes related to the Wisconsin Steel
property. In 1997, the U.S. Department of Justice and Transportation approved
the final consent decree related to the Wisconsin Steel property and the
Company paid $11 million to the Economic Development Administration.
 
  The Company has been named a potentially responsible party ("PRP"), in
conjunction with other parties, in a number of cases arising under an
environmental protection law known as the Superfund law. These cases involve
sites which allegedly have received wastes from current or former Company
locations. Based on information available to the Company, which in most cases
consists of data related to quantities and characteristics of material
generated at or shipped to each site as well as cost estimates from PRPs
and/or federal or state regulatory agencies for the cleanup of these sites, a
reasonable estimate is calculated of the Company's share, if any, of the
probable costs and is provided for in the financial statements. These
obligations generally are recognized no later than completion of the remedial
feasibility study and are not discounted to their present value. The Company
reviews its accruals on a regular basis and believes that, based on these
calculations, its share of the potential additional costs for the cleanup of
each site will not have a material effect on the Company's financial results.
 
DERIVATIVE FINANCIAL INSTRUMENTS
 
  As disclosed in Notes 1 and 10 to the Financial Statements, the Company uses
derivative financial instruments to transfer or reduce the risks of foreign
exchange and interest rate volatility, and potentially increase the return on
invested funds. Company policy does not allow the use of derivatives for
speculative purposes.
 
                                      33
<PAGE>
 
  The Company's manufacturing operations, as conditions warrant, hedge foreign
exchange exposure on the purchase of parts and materials from foreign
countries and its exposure from sales of manufactured products in other
countries. Contracted purchases of commodities for manufacturing may be hedged
up to one year. The manufacturing operations had no foreign exchange exposure
at October 31, 1997.
 
  NFC uses interest rate caps, interest rate swaps and forward interest rate
contracts when needed to convert floating rate funds to fixed and vice versa
to match its asset portfolio. NFC also uses forward interest rate contracts to
manage its exposure to fluctuations in funding costs from the anticipated
securitization and sale of retail notes. During 1997, NFC entered into $500
million of interest rate hedge agreements in anticipation of the November 1997
sale of retail receivables. These hedge agreements were closed in conjunction
with the pricing of the sale, and the loss at October 31, 1997, which was not
material, was deferred and reduced the gain recognized on the sale of
receivables in November 1997.
 
  Both manufacturing operations and NFC purchase collateralized mortgage
obligations that have relatively stable cash flow patterns in relation to
interest rate changes.
 
YEAR 2000
 
  The Company has made and will make certain investments in its software
systems and applications to ensure that the Company is Year 2000 compliant.
The financial impact to the Company has not been and is not anticipated to be
material to its financial position or results of operations.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
  In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings Per Share." This
statement specifies the computation, presentation and disclosure requirements
for earnings per share and is effective for financial statements issued for
periods ending after December 15, 1997. The standard is not expected to have a
material effect on the Company's net income per common share computation.
 
  In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income"
("SFAS 130"), and Statement of Financial Accounting Standards No. 131,
"Disclosures about Segments of an Enterprise and Related Information" ("SFAS
131"). SFAS 130 establishes standards for reporting and display of
comprehensive income and its components. SFAS 131 establishes standards for
reporting information about operating segments, and related disclosures about
products and services, geographic areas and major customers. These statements
are effective for fiscal years beginning after December 15, 1997. These
standards expand or modify disclosures and, accordingly, will have no impact
on the Company's reported financial position, results of operations and cash
flows. The Company is assessing the impact of SFAS 131 on its reported
segments.
 
  In February 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 132, "Employers' Disclosures about
Pensions and Other Postretirement Benefits." This statement revises standards
for disclosures about pension and other postretirement benefit plans and is
effective for fiscal years beginning after December 15, 1997. This standard
expands or modifies disclosure and, accordingly will have no impact on the
Company's reported financial position, results of operations and cash flows.
 
INCOME TAXES
 
  The Statement of Financial Condition at October 31, 1997 and 1996 includes a
deferred tax asset of $934 million and $1,030 million, respectively, net of
valuation allowances of $309 million related to future tax benefits. The
deferred tax assets are net of valuation allowances since it is more likely
than not that some portion of the deferred tax asset may not be realized in
the future.
 
  The deferred tax asset includes the tax benefits associated with cumulative
tax losses of $1,808 million and temporary differences, which represent the
cumulative expense of $1,413 million recorded in the Statement of Income that
has not been deducted on the Company's tax returns. The valuation allowance at
October 31, 1997 assumes that it is more likely than not that approximately
$815 million of cumulative tax losses will not be realized before their
expiration date. Realization of the net deferred tax asset is dependent on the
generation of approximately $2,500 million of future taxable income, of which
an average of approximately $75 million would
 
                                      34
<PAGE>
 
need to be generated annually for the 14-year period 1998 through 2011. The
remaining taxable income, which represents the realization of tax benefits
associated with temporary differences, does not need to be generated until
subsequent to 2011. Until the Company has utilized its significant NOL
carryforwards, the cash payment of federal income taxes will be minimal. See
Note 3 to the Financial Statements.
 
  Extensive analysis is performed to determine the amount of the deferred tax
asset. Such analysis is based on the premise that the Company is and will
continue to be a going concern and that it is more likely than not that
deferred tax benefits will be realized through the generation of future
taxable income. Management reviews all available evidence, both positive and
negative, to assess the long-term earnings potential of the Company using a
number of alternatives to evaluate financial results in economic cycles at
various industry volume conditions based upon the Company's current operating
structure. Other factors considered are the Company's 17-consecutive-year
leadership in the combined market share of Class 5 through 8 trucks and
recognition as a worldwide leading producer of mid-range diesel engines. The
projected availability of taxable income to realize the tax benefit from net
operating loss carryforwards and the reversal of temporary differences before
expiration of these benefits are also considered. The valuation allowance may
be adjusted in the future as a result of changes in business and industry
conditions, operating structure, Company strategies or other significant
transactions. Management believes that, with the combination of available tax
planning strategies and the maintenance of significant market share, earnings
are achievable in order to realize the net deferred tax asset of $934 million.
 
  Reconciliation of the Company's income before income taxes for financial
statement purposes to United States taxable income for the years ended October
31 is as follows:

  The Company contributed approximately $215 million to its hourly and
salaried pension plans in fiscal 1997. The timing of these contributions
allowed for their deduction on the Company's 1996 tax return, which resulted
in a tax loss of $178 million as compared to the $37 million of taxable income
previously reported.

                                   BUSINESS
 
  Navistar, through its wholly owned subsidiary Transportation, operates in
two principal industry segments: manufacturing and financial services.
Manufacturing operations are responsible for the manufacture and marketing of
medium and heavy trucks, including school buses, mid-range diesel engines and
service parts primarily in the United States and Canada as well as in selected
export markets. Based on assets and revenues, manufacturing operations
represent the majority of the Company's business activities. The financial
services operations consist of NFC, its domestic insurance subsidiary and the
Company's foreign finance and insurance subsidiaries. NFC's primary business
is the retail and wholesale financing of products sold by the manufacturing
operations and its dealers within the United States and the providing of
commercial physical damage and liability insurance to the manufacturing
operations' dealers and retail customers and to the general public through an
independent insurance agency system. Industry segment data for 1997, 1996 and
1995 is summarized in Note 14 to the Financial Statements, which is included
elsewhere in this Prospectus.
 
THE MEDIUM AND HEAVY TRUCK INDUSTRY
 
  The market in which Navistar competes is subject to considerable volatility
as it moves in response to cycles in the overall business environment and is
particularly sensitive to the industrial sector which generates a significant
portion of the freight tonnage hauled. Government regulation has impacted and
will continue to impact trucking operations and efficiency and the
specifications of equipment.
 
  The following table shows industry retail deliveries in the combined United
States and Canadian markets for the five years ended October 31, in thousands
of units:

Automobile Manufacturers Associations ("AAMA") in the United States and
Canada, and other sources.
 
  The Class 5 through 8 truck market in the United States and Canada is highly
competitive. Major domestic competitors include PACCAR, Ford and General
Motors, as well as foreign-controlled domestic manufacturers, such as
Freightliner, Mack and Volvo GM. In addition, manufacturers from Japan (Hino,
Isuzu, Nissan and Mitsubishi) are competing in the United States and Canadian
markets. The intensity of this competition results in price discounting and
margin pressures throughout the industry. In addition to the influence of
price, market position is driven by product quality, engineering, styling,
utility and distribution.
 
TRANSPORTATION MARKET SHARE
 
  Transportation delivered 99,500 Class 5 through 8 trucks, including school
buses, in the United States and Canada in fiscal 1997, a 6% increase from the
94,000 units delivered in 1996. Navistar's combined share of the Class 5
through 8 truck market was 28.6% in 1997 and 27.5% in 1996. Transportation has
been the leader in combined market share for Class 5 through 8 trucks,
including school buses, in the United States and Canada in each of its last 17
fiscal years based on data obtained from the AAMA, the United States Motor
Vehicle Manufacturers Association and R.L. Polk & Company.

COMPETITIVE STRENGTHS
 
  The Company believes that its key competitive strengths include the
following:
 
  Leading Market Position. The Company has been the leader in the combined
market share for Class 5 through 8 trucks, including school buses, in the
United States and Canada in each of its last 17 fiscal years. In fiscal 1997,
the Company's combined market share of the Class 5 through 8 truck market was
28.6%, a 1.1 percentage point increase in market share from the previous year.
For each of the last five fiscal years, the Company has been the leader in the
medium truck and school bus markets. In addition, the Company believes that it
is the largest supplier of replacement parts to the heavy and medium truck and
bus aftermarkets.
 
  Commitment to Customer Satisfaction. In order to achieve high customer
satisfaction, the Company maintains the largest retail organization in North
America specializing in medium and heavy trucks. In addition, the Company
operates seven regional parts distribution centers in the United States and
Canada, enabling it to offer 24-hour availability and same day shipment of the
parts most frequently requested by customers. In 1997, Navistar was ranked
number one for the third consecutive year by the annual ATD Attitude Survey,
which evaluates OEMs on quality and performance issues related to products,
parts, policies and service.
 
  Largest Supplier of Mid-Range Diesel Engines. The Company is the leading
supplier of mid-range diesel engines in the 160-300 horsepower range and is
currently the exclusive supplier of diesel engines to Ford for use in its
diesel-powered light trucks and vans. On October 29, 1997, the Company
finalized its agreement with Ford to supply newly-designed, advanced
technology engines through the year 2012 for use in Ford's F-series pickup
trucks and Econoline vans. This 10-year agreement is scheduled to become
effective beginning with model year 2003 and will replace the Company's
current agreement with Ford, which will expire after model year 2002. The
Company has been supplying diesel engines to Ford since 1982.
 
TRUCK STRATEGY
 
  In fiscal 1997, the Company continued to implement its five-point truck
strategy, which the Company adopted in fiscal 1996 in order to improve
operating performance and increase profitability. Specifically, this strategy
is designed to enable Transportation's truck division to achieve its part in
Navistar's goal of generating an average 17.5% after tax return on equity over
a business cycle. The principal components of this strategy as well as recent
achievements in its implementation include:
 
  . Reduce Product Complexity. The Company believes that it can increase
    manufacturing efficiency and improve product quality by reducing the
    complexity of its product offerings. Historically, thousands of options
    and a separate chassis design were offered for each truck model
    manufactured by Transportation, which led to significant manufacturing
    inefficiencies. In 1996, Transportation introduced a new ordering program
    known as Diamond Spec(TM) for its premium conventional heavy duty trucks.
    Under this program, Transportation rationalized the number of possible
    option combinations by developing pre-packaged option groups which are
    arranged under 11 categories (i.e., engine, chassis, electrical system)
    based upon the most popular preferences of its customers. Transportation
    also combined the chassis for three models offered in this premium
    conventional product category into one chassis. In 1997, Transportation
    expanded its Diamond Spec(TM) ordering system and completed a successful
    pilot program in 11 key markets for its medium trucks. This
    standardization of option and chassis groups is expected to lead to
    significant operating cost savings from increased manufacturing
    efficiency and to better pricing for purchased components. In addition,
    Transportation believes that this program will result in an overall
    improvement in product quality and shorter and more reliable delivery
    times.
 
  . Focus Manufacturing Facilities. The Company believes that it can achieve
    significant improvements in manufacturing efficiency by focusing each of
    its principal truck manufacturing facilities on producing a single type
    of truck model. In order to sharpen the Company's focus on serving its
    customers and markets, the Company recently announced a reorganization of
    its truck group into six distinct businesses. The new organization will
    consist of four vehicle centers--heavy truck, severe service truck,
    medium truck and school bus, and two business centers--parts and
    international. In fiscal 1996, Transportation transferred the production
    of its stripped chassis from its Springfield, Ohio facility to its
    Conway, Arkansas facility, in order to achieve efficiencies in the
    production of medium duty trucks. Similarly, the Company established a
    joint venture, SST Truck Company, which will focus on the production of
    the
 
                                      37
<PAGE>
 
   highly-complex Paystar(R) severe service trucks, thereby permitting
   Transportation's Chatham, Ontario facility to concentrate on
   manufacturing premium conventional heavy duty trucks.
 
  . Emphasize Product Development. The Company believes that each of its
    current truck models equals or exceeds those of its competitors in terms
    of satisfying its customers' needs. Nevertheless, the Company intends to
    continue to enhance and expand its current product offerings in an effort
    to provide trucks that better satisfy its customers' changing demands. In
    fiscal 1997, Navistar's Board of Directors approved funding for the NGT
    Program. Pursuant to the NGT Program, the Company expects to invest $350
    million in capital and spend $300 million in development costs over the
    next six years to develop and manufacture a full line of world-class
    medium trucks, school buses and regular conventional heavy trucks, which
    will offer enhanced driver comfort, operating efficiency, overall
    appearance, quality and performance. The design and development phases of
    the NGT Program are currently underway and the Company expects the first
    new vehicles to be available in mid-2001, with additional new vehicles to
    follow approximately every six months through 2003. In 1997,
    Transportation also introduced the International 9100 conventional truck
    to replace its 8200 heavy duty regular conventional truck and made
    significant improvements to its premium conventional models. Further
    model improvements are expected to be introduced for Transportation's
    premium conventional heavy duty truck models in fiscal 1998.
 
  . Expand International Operations. The Company believes that there are
    significant opportunities to increase sales of both trucks and engines in
    Mexico and in other selected export markets. In 1997, the Company
    captured approximately 11.5% of the Mexican truck market after
    establishing a dealer network and a parts distribution center and
    arranging for production at a contract manufacturer in 1996. The
    Company's dealer network in Mexico was expanded from 23 to 38 locations
    in 1997. The Company is currently constructing an assembly facility
    located near Monterrey, Mexico. This medium duty and heavy duty truck
    facility is anticipated to cost approximately $167 million and to begin
    production by late-1998. Its capacity will be 65 units per shift. The
    Company believes that its Mexican operations will enable it to expand
    into other Latin American countries, particularly as a result of the
    favorable and cost effective trade agreements between Mexico and other
    Latin American countries. The Company has also recently established a
    presence in Brazil by forming a Brazilian subsidiary and signing an
    agreement with a Brazilian equipment manufacturer to assemble commercial
    trucks. The Company expects that production of its trucks in Brazil will
    begin in late 1998.
 
  . Establish Competitive Wage, Benefit and Productivity Levels.
    Transportation expects to achieve significant productivity gains as a
    result of favorable changes in job classifications, work rules and
    training. In August 1997, Transportation's collective bargaining
    agreement with the UAW was extended through October 1, 2002. This
    contract contains significant changes from the prior agreement, enabling
    the Company to better focus its assembly plants, simplify current product
    lines, invest in new product development and achieve more competitive
    wage, benefit and productivity levels. This new agreement enabled the
    Company to reinstate its NGT Program and continue to implement its five-
    point truck strategy. In 1996, Transportation signed a new three-year
    collective bargaining agreement with the CAW.

  Transportation manufactures a full line of products in the common carrier,
private carrier, government/service, leasing, construction, energy/petroleum
and student transportation markets. Transportation offers diesel-powered
trucks and buses because of their improved fuel economy, ease of
serviceability and greater durability over gasoline-powered vehicles.
Transportation's Class 8 heavy trucks generally use diesel engines purchased
from outside suppliers while Class 5, 6 and 7 medium trucks are powered by a
proprietary line of mid-range diesel engines manufactured by Transportation.
Based upon information published by R.L. Polk & Company, diesel-powered Class
5, 6 and 7 medium truck shipments represented 87% of all medium truck
shipments for fiscal year 1997 in the United States and Canada.
 
  Transportation's truck and bus manufacturing operations in the United States
and Canada consist principally of the assembly of components manufactured by
its suppliers, although Transportation produces its own mid-range diesel truck
engines, sheet metal components (including cabs) and miscellaneous other
parts. During 1997, the Company announced plans for approximately $350 million
in capital spending and $300 million in development expense over the next six
years for development of its next generation truck.
 
ENGINE AND FOUNDRY
 
  Transportation builds diesel engines for use in its Class 5, 6 and 7 medium
trucks, school buses, selected Class 8 heavy truck models and for sale to
original equipment manufacturers in the United States and Canada.
Transportation also sells engines for industrial, agricultural and marine
applications. Transportation is the leading supplier of mid-range diesel
engines in the 160-300 horsepower range according to data supplied by Power
Systems Research of Minneapolis, Minnesota.
 
  Transportation has an agreement to supply its 7.3 liter (7.3L)
electronically controlled diesel engine to Ford through the year 2002 for use
in all of Ford's diesel-powered light trucks and vans. Sales of this engine to
Ford currently account for approximately 87% of Transportation's 7.3L sales.
Shipments of engines to all original equipment manufacturers totaled a record
184,000 units in 1997, an increase of 13% from the 163,200 units shipped in
1996. During 1997, Transportation entered into a ten-year agreement, effective
with model year 2003, to supply Ford with a 7.3L replacement product for use
in its diesel-powered light trucks and vans.
 
SERVICE PARTS
 
  In the United States and Canada, Transportation operates seven regional
parts distribution centers, which allows it to offer 24-hour availability and
same day shipment of the parts most frequently requested by customers. The
Company also operates a parts distribution center in Mexico.
 
  Transportation's service parts program is vital to the maintenance of the
relationship with its customers and dealers. The sale of replacement parts
does not represent a separate and distinct business of Transportation.
Transportation's truck group makes decisions about the pricing of trucks and
replacement parts based upon a variety of factors which integrally link the
pricing and sale of replacement parts with the sale of medium and heavy
trucks, including school buses. The acceptable price for dealers and fleet
truck sales is determined by not only looking at the market price of the
individual trucks themselves, but also by analyzing the amount of future
replacement parts that will be purchased from Transportation over the truck's
life cycle and the total expected profit contribution, including future
replacement parts, expected to be realized on each sale. Accordingly, the
pricing of trucks and replacement parts is not independently determined.
 
MARKETING AND DISTRIBUTION
 
  Transportation's truck products are distributed in virtually all key markets
in the United States and Canada. Transportation's truck distribution and
service network in these countries was composed of 954, 957 and 958 dealers
and retail outlets at October 31, 1997, 1996 and 1995, respectively. Included
in these totals were 514, 504 and 490 secondary and associate locations at
October 31, 1997, 1996 and 1995, respectively. The Company also has a dealer
network in Mexico composed of 38 and 23 dealer locations at October 31, 1997
and 1996, respectively.
 
                                      39
<PAGE>
 
  Retail dealer activity is supported by five regional operations in the
United States and general offices in Canada and Mexico. Transportation has a
national account sales group, responsible for 99 major national account
customers. Transportation's network of 16 Used Truck Centers in the United
States provides trade-in support to the Company's dealers and national
accounts group, and markets all makes and models of reconditioned used trucks
to owner-operators and fleet buyers. Trucks, components and service parts are
exported for wholesale and retail sale to more than 70 countries around the
world.
 
FINANCIAL SERVICES
 
  NFC is a financial services organization that provides wholesale, retail and
lease financing of new and used trucks sold by Transportation and its dealers
in the United States. NFC also finances wholesale accounts and selected retail
accounts receivable of Transportation. Sales of new products (including
trailers) of other manufacturers are also financed regardless of whether
designed or customarily sold for use with Transportation's truck products.
During 1997 and 1996, NFC provided wholesale financing for 94% of the new
truck units sold by Transportation to its dealers and distributors in the
United States and retail and lease financing for 13% and 16%, respectively, of
all new truck units sold or leased by Transportation to retail customers.
 
  NFC's wholly owned domestic insurance subsidiary, Harco National Insurance
Company, provides commercial physical damage and liability insurance coverage
to Transportation's dealers and retail customers, and to the general public
through an independent insurance agency system.
 
  Harbour Assurance Company of Bermuda Limited offers a variety of programs to
the Company, including general liability insurance, ocean cargo coverage for
shipments to and from foreign distributors, and reinsurance coverage for
various Transportation policies.
 
IMPORTANT SUPPORTING OPERATIONS
 
  Navistar International Corporation Canada has an agreement with a subsidiary
of General Electric Capital Canada, Inc. to provide financing for Canadian
dealers and customers.
 
RESEARCH AND DEVELOPMENT
 
  Research and development activities, which are directed toward the
introduction of new products and improvements of existing products and
processes used in their manufacture, totaled $92 million, $101 million, and
$91 million for 1997, 1996 and 1995, respectively.
 
BACKLOG
 
  The backlog of unfilled truck orders (subject to cancellation or return in
certain events) at October 31, 1997, 1996 and 1995 was $2,360 million, $1,254
million and $2,581 million, respectively.
 
  Although the backlog of unfilled orders is one of many indicators of market
demand, other factors such as changes in production rates, available capacity,
new product introductions and competitive pricing actions may affect point-in-
time comparisons.
 
EMPLOYEES
 
  The Company employed 16,168, 14,187 and 16,079 individuals at October 31,
1997, 1996 and 1995, respectively.
 
LABOR RELATIONS
 
  At October 31, 1997, the UAW represented 8,079 of the Company's active
employees in the United States, and the CAW represented 2,142 of the Company's
active employees in Canada. Other unions represented 955 of
 
                                      40
<PAGE>
 
the Company's active employees in the United States and Canada. The Company
entered into a collective bargaining agreement with the UAW in 1995, which
would have expired on October 1, 1998. During August 1997, the Company's
collective bargaining agreement with the UAW was extended through October 1,
2002. This contract allows the Company to focus its assembly plants, simplify
current product lines, invest in new product development, and achieve more
competitive wage, benefit and productivity levels. In addition, the Company
entered into a collective bargaining agreement with the CAW in 1996, which
expires on October 24, 1999.
 
PATENTS AND TRADEMARKS
 
  Transportation continuously obtains patents on its inventions and, thus,
owns a significant patent portfolio. Additionally, many of the components
which Transportation purchases for its products are protected by patents that
are owned or controlled by the component manufacturer. Transportation has
licenses under third-party patents relating to its products and their
manufacture, and Transportation grants licenses under its patents. The
royalties paid or received under these licenses are not significant. No
particular patent or group of patents is considered by Transportation to be
essential to its business as a whole.
 
  Like all businesses which offer well-known products or services,
Transportation's primary trademarks are an important part of its worldwide
sales and marketing efforts, and provide instant identification of its
products and services in the marketplace. To support these efforts,
Transportation maintains, or has pending, registrations of its primary
trademarks in those countries in which it does business or expects to do
business.
 
RAW MATERIALS AND ENERGY SUPPLIES
 
  Transportation purchases raw materials, parts and components from numerous
outside suppliers but relies upon some suppliers for a substantial number of
components for its truck and engine products. A majority of Transportation's
requirements for raw materials and supplies is filled by single-source
suppliers.
 
  The impact of an interruption in supply will vary by commodity. Some parts
are generic to the industry while others are of a proprietary design requiring
unique tooling which would require time to recreate. However, the Company's
exposure to a disruption in production as a result of an interruption of raw
materials and supplies is no greater than the industry as a whole. In order to
remedy any losses resulting from an interruption in supply, the Company
maintains contingent business interruption insurance for storms, fire and
water damage.
 
  While the Company believes that it has adequate assurances of continued
supply, the inability of a supplier to deliver could have an adverse effect on
production at certain of the Company's manufacturing locations.
 
IMPACT OF GOVERNMENT REGULATION
 
  Truck and engine manufacturers continue to face increasing governmental
regulation of their products, especially in the areas of environment and
safety. The Company believes its products comply with all applicable
environmental and safety regulations.
 
  As a diesel engine manufacturer, the Company has incurred research and
tooling costs to redesign its engine product lines to meet the U.S. EPA and
CARB emission standards effective for the 1998 model year. In addition to the
1998 standards, the Company, along with other engine manufacturers, has signed
a voluntary agreement with U.S. EPA and CARB to achieve new reductions in
ozone-causing exhaust emissions by 2004 (the "Statement of Principles"). In
October 1997, as a result of the Statement of Principles, the U.S. EPA issued
a final rule defining heavy-duty emission requirements for the 2004 model
year. The Company will also provide engines that satisfy 1998 Clean Fuel Fleet
Vehicle requirements and must also satisfy California's emission standards in
2002 for engines used in medium-size vehicles (which includes vehicles up to
14,000 lbs. Gross Vehicle Weight Rating). The Company expects that its diesel
engines will be able to meet all of these standards within the required time
frame. For model year 1998, the U.S. EPA has issued conditional certification
of conformance for all electronically-controlled diesel engines while it
investigates whether these engines fully
 
                                      41
<PAGE>
 
comply with regulations concerning nitrogen oxide emissions. In particular,
the U.S. EPA is focusing on whether certain electronics strategies used to
maintain fuel economy have an adverse impact on nitrogen oxide emissions.
Navistar believes the diesel engines manufactured by it are in compliance with
all applicable U.S. EPA standards and is cooperating with the U.S. EPA's
investigation. It is possible that the U.S. EPA investigation could result in
some buyers deferring their purchases of trucks pending the outcome of the
investigation, and that future U.S. EPA action could impact the fuel economy
of trucks.
 
  Effective with the 1998 model year, Canada's emission standards mirror those
of the U.S. EPA and require the sale of low-sulfur diesel fuel effective
October 1, 1997. Mexico has adopted the U.S. heavy diesel engine emission
standards as of the 1994 model year but has conditioned compliance on the
availability of low-sulfur diesel fuel.
 
  Truck manufacturers are also subject to various noise standards imposed by
federal, state and local regulations. The engine is one of a truck's primary
noise sources, and the Company, therefore, works closely with original
equipment manufacturers to develop strategies to reduce engine noise. The
Company is also subject to the National Traffic and Motor Vehicle Safety Act
("Safety Act") and Federal Motor Vehicle Safety Standards ("Safety Standards")
promulgated by the National Highway Traffic Safety Administration. The Company
believes it is in compliance with the Safety Act and the Safety Standards.
 
  Expenditures to comply with various environmental regulations relating to
the control of air, water and land pollution at production facilities and to
control noise levels and emissions from Transportation's products have not
been material except for two sites formerly owned by the Company, Wisconsin
Steel in Chicago, Illinois, and Solar Turbine in San Diego, California. In
1994, Transportation recorded a $20 million after-tax charge as a loss of
discontinued operations for environmental liabilities and cleanup cost at
these two sites. It is not expected that the costs of compliance with
foreseeable environmental requirements will have a material effect on the
Company's financial position or operating results.
 
PROPERTIES
 
  In the United States and Canada, Transportation owns and operates eight
manufacturing and assembly operations, which contain approximately nine
million square feet of floor space. Four facilities manufacture and assemble
trucks, two plants manufacture diesel engines and two locations produce gray
iron castings. The Company also manufactures trucks at a facility owned and
operated through a joint venture in the U.S. and is constructing a truck
assembly facility in Mexico. In addition, Transportation owns or leases other
significant properties in the United States and Canada including vehicle and
parts distribution centers, sales offices, an engineering center and its
headquarters in Chicago.
 
  Transportation's principal research and engineering facilities are located
in Fort Wayne, Indiana, and Melrose Park, Illinois. In addition, certain
research is conducted at its manufacturing plants.
 
  All of Transportation's plants are being utilized and have been maintained
adequately, are in good operating condition and are suitable for its current
needs through productive utilization of the facilities. These facilities,
together with planned capital expenditures, are expected to meet
Transportation's manufacturing needs in the foreseeable future.
 
  A majority of the activity of the financial services operations is conducted
from its leased headquarters in Rolling Meadows, Illinois. The financial
services operations also lease six other office locations in the United
States.
 
LEGAL PROCEEDINGS
 
  The Company and its subsidiaries are subject to various claims arising in
the ordinary course of business, and are parties to various legal proceedings
which constitute ordinary routine litigation incidental to the business of the
Company and its subsidiaries. In the opinion of the Company's management, none
of these proceedings or claims are material to the business or the financial
condition of the Company.

CERTAIN ARRANGEMENTS WITH NFC
 
 Master Intercompany Agreement
 
  The operating relationship between Transportation and NFC is governed by the
terms of a master intercompany agreement dated as of April 26, 1993 and as
amended on September 30, 1996 (the "Master Intercompany Agreement"). The
Master Intercompany Agreement requires, among other things, that
Transportation, with limited exceptions, offer NFC all wholesale and retail
notes and installment sales contracts which Transportation acquires in the
regular course of its business from sales of trucks and related equipment to
Transportation's dealers and customers. Such offers must be on terms which
will (together with charges made to others for financing services) afford
reasonable compensation for the financing services rendered by NFC to
Transportation and Transportation's dealers with respect to the sale of
Transportation's products and used goods. NFC in turn has agreed, to the
extent that it is able to finance such purchases, that it will purchase all
such receivables without recourse.
 
  Pursuant to the Master Intercompany Agreement, NFC also purchases
Transportation's wholesale accounts receivable from Transportation's dealers
arising out of Transportation's sales of goods (primarily parts) and services
to such dealers. NFC receives compensation from Transportation in the form of
a floating rate service charge for financing these accounts.
 
  The Master Intercompany Agreement also provides that NFC will purchase
retail accounts receivable from Transportation that arise out of
Transportation's sales to retail customers. NFC receives a floating rate
service charge from Transportation for financing these accounts.
 
 Tax Allocation Agreement
 
  Pursuant to the tax allocation agreement effective October 1, 1981, as
subsequently amended and supplemented (the "Tax Allocation Agreement"), NFC is
required to pay to Transportation an amount equal to the amount NFC and its
subsidiaries would pay with respect to federal corporate income taxes if NFC
and its subsidiaries filed federal tax returns on a consolidated basis as an
affiliated group of corporations, notwithstanding the fact that the affiliated
group of corporations including Navistar and its subsidiaries may not have any
federal tax liability. The Tax Allocation Agreement contains similar
provisions regarding state income taxes for states that permit the filing of
consolidated returns.
 
 Side Agreement
 
  The Amended and Restated Parent's Side Agreement dated as of November 8,
1994, between NIC and Transportation (the "Side Agreement") requires either
Transportation or NIC to hold and own 100% of the outstanding voting stock of
NFC (other than shares held by directors of NFC as qualifying shares). The
Side Agreement also requires Transportation not to permit NFC's consolidated
income before income taxes, interest expense and dividends on preferred stock
to be less than 125% of NFC's consolidated interest expense and dividends on
preferred stock for any period of four fiscal quarters immediately preceding
the date of measurement.

                  DESCRIPTION OF OTHER FINANCING ARRANGEMENTS
 
MEXICO CREDIT AGREEMENT
 
  In November 1997, NIC and Navimex entered into a credit agreement (the
"Mexico Credit Agreement") with a group of banks. The commitment of the Mexico
Credit Agreement is $125 million, including $65 million in a U.S. dollar
tranche and the equivalent of $60 million in Mexican pesos for a peso tranche.
The facility is a multiple drawdown term credit facility, the proceeds of
which are to be used for the construction of the Company's new assembly
facility near Monterrey, Mexico. The maturity date of the Mexico Credit
Agreement is December 2002. Borrowings under the Mexico Credit Agreement are
secured by all of the assets of Navimex and are guaranteed by NIC.
 
  All amounts borrowed under the commitment are to be drawn pro-rata between
the U.S. dollar tranche and the peso tranche. With respect to all U.S. dollar
loans, Navimex has elected a fixed interest rate of 6 1/8% plus a margin based
on NIC's long-term credit rating. The interest rate on peso loans is based on
the Interbank Interest Equilibrium Rate calculated by the Banco de Mexico,
plus a margin based on NIC's long-term credit rating.
 
  The Mexico Credit Agreement includes a number of restrictive covenants,
which require NIC to maintain (i) a consolidated net worth (which includes
certain amounts of subordinated indebtedness) of at least $850 million plus
50% of positive net earnings for each fiscal year commencing with fiscal year
1997 plus 50% of the net cash proceeds to NIC of any primary sales of capital
stock, (ii) a cash flow coverage ratio of at least 1.25 to 1, and (iii) a
minimum cash reserve equal to 75% at fiscal year end and 50% at any other time
of the aggregate outstanding amount of all loans under the Mexico Credit
Agreement. In addition, NIC's total consolidated debt to the sum of its total
consolidated debt plus its consolidated net worth may not exceed certain
prescribed ratios.
 
  The Mexico Credit Agreement also limits the amount of investments that NIC
and Navimex can make and the amount of debt each can incur, subject to certain
limited exceptions, and contains a negative pledge which prevents NIC and
Navimex from incurring or suffering to exist liens on its assets, except in
certain limited circumstances. The Mexico Credit Agreement also contains
covenants regarding reporting, insurance, conduct of business, maintenance of
existence and compliance with laws and customary events of default.
 
NFC BANK CREDIT AGREEMENT
 
  NFC has a $925 million Credit Agreement which matures in March 2001. Under
the terms of the Credit Agreement, NFC may (i) lend up to $100 million to
Transportation, secured by Transportation's service parts and new and used
truck inventories; and (ii) receive up to $50 million of credit in its asset
base calculation for Mexican retail and wholesale receivables funded by NFC.
Amounts outstanding under the Credit Agreement are secured by all the assets
of NFC, including a pledge of all of the stock of each of NFC's subsidiaries.
 
  Three interest rate options are available for borrowings under the Credit
Agreement: (i) Base Rate Loans, tied to the higher of the prime rate or the
sum of 1/2 of 1% plus the Federal Funds rate; (ii) CD Loans, based on the
prevailing Certificate of Deposit rate; and (iii) Euro-Dollar Loans, based on
the London interbank offered rate ("LIBOR"), in each case plus a margin based
on NFC's long-term credit rating.
 
  The Credit Agreement includes a number of restrictive covenants. For
example, NFC is required to maintain (i) a consolidated tangible net worth of
at least $175 million and (ii) consolidated interest expense, preferred stock
dividends and consolidated income before income taxes that is at least 125% of
its fixed charges (consisting of consolidated interest expense and preferred
stock dividends). In addition, NFC's total consolidated debt to consolidated
tangible net worth may not exceed 7 to 1. NFC may not transfer its accounts
receivable or prepay subordinated debt below $100 million, except in
accordance with the terms contained in the Credit Agreement.
 
  In addition, the Credit Agreement requires NFC to hold all of the
outstanding stock of each of its subsidiaries. The Credit Agreement requires
that NFC perform all of its obligations under the Master Intercompany
Agreement, not consent to amendments or modifications thereof which would be
materially
 
                                      45
<PAGE>
 
adverse to NFC (except in certain limited circumstances) and enforce the
Master Intercompany Agreement against Transportation in accordance with its
terms. NFC is prohibited from engaging in transactions with affiliates (except
in certain limited circumstances) that are not in the ordinary course of
business and on an arm's-length basis. The Credit Agreement also requires that
NFC maintain adequate loan loss reserves and its current dealer guideline
program. The Credit Agreement also contains additional covenants and events of
default that are customary to this type of financing.
 
SECURITIZATION PROGRAMS
 
  NFC presently utilizes securitizations to fund a substantial portion of its
acquisitions of wholesale notes and retail notes (together with lease
receivables, the "receivables"). NFC relies upon the securitization market,
which provides it with funding at rates offered to companies with investment
grade ratings. NFC anticipates continuing to utilize securitizations to fund
its acquisitions of wholesale notes and retail notes.
 
 Wholesale Notes Securitizations
 
  Since 1990, NFC has securitized its wholesale notes. On a daily basis, NFC
sells all newly arising wholesale notes, except those which are ineligible and
those which exceed a dealer concentration level which is set by NFC (subject
to a contractual maximum), to Navistar Financial Securities Corporation
("NFSC"), a wholly owned special purpose subsidiary of NFC. NFSC in turn sells
the wholesale notes to a trust, which effectively reinvests collections on
outstanding trust receivables in such newly originated wholesale notes. NFSC
retains an interest in the trust, a portion of which is subordinated to the
investor certificates. At October 31, 1997, NFSC's retained interest in the
trust constituted $120 million, of which $100 million was subordinated to
claims of investor certificateholders.
 
 Retail Notes Securitizations
 
  Since 1993, NFC has securitized a significant portion of its retail loans.
Approximately twice a year, NFC sells a pool of retail loans, certain monies
due or received thereunder, security interests in the vehicles and equipment
financed thereby and certain other property (collectively, the "Property") to
NFRRC, a wholly owned special purpose subsidiary of NFC. Immediately
thereafter, NFRRC transfers such Property to a trust formed specifically for
such transactions in exchange for either asset-backed notes or certificates
issued by such trust. NFC retains the option under certain circumstances to
repurchase the remaining pool of retail loans of any trust once monies due and
payable thereunder constitute 10% or less of aggregate amount due and payable
under such retail loans when initially purchased by the trust. NFRRC retains a
residual interest in each trust.
 
  As of October 31, 1997, trusts formed by NFRRC have issued an aggregate
principal amount of approximately $3,776 million of asset-backed securities.
Each class of asset-backed securities may have a different interest rate. At
October 31, 1997, asset-backed securities from seven securitized transactions
originated by NFRRC remained outstanding and had a remaining aggregate
principal balance of approximately $1,367 million.
 
 Asset-Backed Commercial Paper Program
 
  NFC and Truck Retail Instalment Paper Corp. ("TRIP"), a wholly owned
subsidiary of NFC, established NFC Asset Trust (the "ABCP Trust") in late 1994
for the purpose of issuing asset-backed commercial paper. As a condition to
issuance, all commercial paper must be rated at least "A-1" by Standard &
Poor's Ratings Group and "P-1" by Moody's. NFC currently may issue up to $400
million in face amount of commercial paper under the ABCP Program. The ABCP
Trust has also issued approximately $14 million of subordinated certificates.
At October 31, 1997, the ABCP Trust had outstanding commercial paper of $388
million.
 
  NFC currently uses the ABCP Program to warehouse its retail loans pending a
permanent securitization of such loans as described above. To support the
commercial paper program, NFC has arranged a liquidity facility
 
                                      46
<PAGE>
 
with a syndicate of banks. Loans under the liquidity facility are available
either to repay maturing commercial paper if sufficient funds are not
otherwise available or to fund loans to TRIP. The lenders provide liquidity,
not credit support, for the ABCP Trust. The lenders' commitments under the
liquidity facility terminate in March 2001.
 
SALE-LEASEBACKS
 
  During 1997, NFC entered into sale-leaseback agreements involving vehicles
subject to retail finance and operating leases with end users. The agreements
grant to the purchasers a security interest in the underlying end user leases.
The aggregate value of the leased vehicles was approximately $105 million. NFC
may effect additional sale-leasebacks in the future.
 
1998 AND 2002 NOTES
 
  NFC's 8 7/8% Senior Subordinated Notes due 1998 (the "1998 Notes") were
issued pursuant to an indenture, dated as of November 15, 1993, between NFC
and First Trust, N.A. (as successor to Continental Bank, National
Association), as Trustee (the "1998 Notes Indenture"). NFC's 9.0% Senior
Subordinated Notes due 2002 (the "2002 Notes" and together with the 1998
Notes, the "NFC Notes") were issued pursuant to an indenture, dated as of May
30, 1997, between NFC and The Fuji Bank & Trust Company, as Trustee (the "2002
Notes Indenture"). The 1998 Notes and the 2002 Notes are each limited to $100
million aggregate principal amount and mature on November 15, 1998 and June 1,
2002, respectively. The NFC Notes are not redeemable by NFC prior to maturity
and are not subject to any mandatory sinking fund payments.
 
  The 1998 Notes Indenture and the 2002 Notes Indenture contain certain
covenants that, among other things, limit the ability of NFC or any of its
subsidiaries to maintain or incur indebtedness, create liens, enter into
certain transactions with affiliates, or consummate certain merger,
consolidation or asset sale transactions. In addition, NFC is required to
maintain a Consolidated Fixed Charge Coverage Ratio of at least 1.25 to 1.0
(as of the end of any fiscal quarter) under the 1998 Notes Indenture, provided
that such ratio will be reduced to 1.10 to 1.0 for any fiscal quarter in which
the 1998 Notes are rated investment grade. These covenants are subject to
certain exceptions and qualifications.
 
  The NFC Notes are general obligations of NFC and are subordinated to all
senior indebtedness of NFC (as defined in the 1998 Notes Indenture or the 2002
Notes Indenture, as applicable). The NFC Notes rank pari passu with all senior
subordinated indebtedness of NFC and rank senior to subordinated indebtedness
of NFC. As a result of the restrictive covenants contained in the 1998 Notes
Indenture and the 2002 Notes Indenture and pursuant to the Credit Agreement,
holders of the NFC Notes are secured, subject to the subordination provisions
contained in such Indenture, equally and ratably with the holders of the
Senior Indebtedness of NFC, by a lien on substantially all of the assets of
NFC. Such lien and security interest is subject to release without prior
notice to, or the consent of, the holders of the 1998 Notes or the 2002 Notes
Indenture, as the case may be.
 
  Upon a Change of Control Triggering Event (as defined in the 1998 Notes
Indenture and the 2002 Notes Indenture), NFC will, subject to certain
conditions, make an offer to purchase all outstanding NFC Notes at a purchase
price of 101% of the principal amount thereof plus accrued and unpaid interest
to the redemption date. The Credit Agreement imposes certain limitations on
the purchase of the NFC Notes upon a Change of Control Triggering Event.

                              THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
  The Old Notes were originally sold by the Company on February 4, 1998 to the
Initial Purchasers pursuant to the Purchase Agreements. The Initial Purchasers
subsequently placed the Old Notes with (i) qualified institutional buyers in
reliance on Rule 144A under the Securities Act and (ii) qualified buyers
outside the United States in reliance upon Registration S under the Securities
Act. As a condition of the Purchase Agreements, the Company entered into the
Registration Rights Agreements with the Initial Purchasers pursuant to which
the Company has agreed, for the benefit of the holders of the Old Notes, at
the Company's cost, to use its best efforts to (i) file the Exchange Offer
Registration Statement within 60 days after the date of the original issue of
the Old Notes (the "Issue Date") with the Commission with respect to the
Exchange Offer for the Exchange Notes, (ii) use its best efforts to cause the
Exchange Offer Registration Statement to be declared effective under the
Securities Act within 150 days after the Issue Date and (iii) unless the
Exchange Offer would not be permitted by applicable law or Commission policy,
commence the Exchange Offer and use its best efforts to issue the Exchange
Notes on or prior to 180 days after the Issue Date. Upon the Exchange Offer
Registration Statement being declared effective, the Company will offer the
Exchange Notes in exchange for surrender of the Old Notes. The Company will
keep the Exchange Offer open for not less than 20 business days (or longer if
required by applicable law) after the date on which notice of the Exchange
Offer is mailed to the holders of the Old Notes. For each Old Note surrendered
to the Company pursuant to the Exchange Offer, the holder of such Old Note
will receive an Exchange Note having a principal amount equal to that of the
surrendered Old Note. Interest on each Old Note will accrue from the last
interest payment date on which interest was paid on the Old Note surrendered
in exchange therefor or, if no interest has been paid on such Old Note, from
the date of its original issue. Interest on each Exchange Note will accrue
from the date of its original issue.
 
  Under existing interpretations of the staff of the Commission contained in
several no-action letters to third parties, the Exchange Notes will in general
be freely tradeable after the Exchange Offer without further registration
under the Securities Act. However, any purchaser of Old Notes who is an
"affiliate" of the Company or who intends to participate in the Exchange Offer
for the purpose of distributing the Exchange Notes (i) will not be able to
rely on the interpretation of the staff of the Commission, (ii) will not be
able to tender its Old Notes in the Exchange Offer and (iii) must comply with
the registration and prospectus delivery requirements of the Securities Act in
connection with any sale or transfer of the Exchange Notes, unless such sale
or transfer is made pursuant to an exemption from such requirements.
 
  As contemplated by these no-action letters and the Registration Rights
Agreements, each holder accepting the Exchange Offer is required to represent
to the Company in the Letter of Transmittal or Agent's Message that (i) the
Exchange Notes are to be acquired by the holder or the person receiving such
Exchange Notes, whether or not such person is the holder, in the ordinary
course of business, (ii) the holder or any such other person (other than a
broker-dealer referred to in the next sentence) is not engaging and does not
intend to engage, in distribution of the Exchange Notes, (iii) the holder or
any such other person has no arrangement or understanding with any person to
participate in the distribution of the Exchange Notes, (iv) neither the holder
nor any such other person is an "affiliate" of the Company within the meaning
of Rule 405 under the Securities Act and (v) the holder or any such other
person acknowledges that if such holder or any other person participates in
the Exchange Offer for the purpose of distributing the Exchange Notes it must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale of the Exchange Notes and cannot
rely on those no-action letters. As indicated above, each Participating
Broker-Dealer that receives an Exchange Note for its own account in exchange
for Old Notes must acknowledge that it (i) acquired the Old Notes for its own
account as a result of market-making activities or other trading activities,
(ii) has not entered into any arrangement or understanding with the Company or
any "affiliate" of the Company (within the meaning of Rule 405 under the
Securities Act) to distribute the Exchange Notes to be received in the
Exchange Offer and (iii) will deliver a prospectus meeting the requirements of
the Securities Act in connection with any resale of such Exchange Notes. For a
description of the procedures for resales by Participant Broker-Dealers, see
"Plan of Distribution."
 
                                      48

  In the event that changes in the law or the applicable interpretations of
the staff of the Commission do not permit the Company to effect such an
Exchange Offer, or if for any other reason the Exchange Offer is not
consummated within 180 days of the Issue Date, the Company will (i) file the
Shelf Registration Statement covering resales of the Old Notes; (ii) use its
reasonable best efforts to cause the Shelf Registration Statement to be
declared effective under the Securities Act and (iii) use its reasonable best
efforts to keep effective the Shelf Registration Statement until two years
after the Issue Date. The Company will, in the event of the filing of the
Shelf Registration Statement, provide to each applicable holder of the Old
Notes copies of the prospectus which is a part of the Shelf Registration
Statement, notify each such holder when the Shelf Registration Statement has
become effective and take certain other actions as are required to permit
unrestricted resale of the Old Notes. A holder of the Old Notes that sells
such Old Notes pursuant to the Shelf Registration Statements generally will be
required to be named as a selling security holder in the related prospectus
and to deliver a prospectus to purchasers, will be subject to certain of the
civil liability provisions under the Securities Act in connection with such
sales and will be bound by the provisions of the Registration Rights
Agreements which are applicable to such a holder (including certain
indemnification obligations). In addition, each holder of the Old Notes will
be required to deliver information to be used in connection with the Shelf
Registration Statement and to provide comments on the Shelf Registration
Statement within the time periods set forth in the Registration Rights
Agreement in order to have its Old Notes included in the Shelf Registration
Statement and to benefit from the provisions set forth in the following
paragraph.
 
  The Registration Rights Agreements provide that (i) the Company will file an
Exchange Offer Registration Statement with the Commission on or prior to 60
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 150 days after the Issue Date, (iii) unless the Exchange Offer
would not be permitted by applicable law or Commission policy, the Company
will commence the Exchange Offer and use its best efforts to issue the
Exchange Note on or prior to 180 days after the Issue Date 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 in a
timely fashion. If (a) the Company fails to file any of the Registration
Statements required by the Registration Rights Agreements or before the date
specified for such filing, (b) any of such Registration Statements is not
declared effective by the Commission on or prior to the date specified for
such effectiveness, or (c) the Company fails to consummate the Exchange Offer
on or prior to the date specified for such consummation, 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 period
specified in the Registration Rights Agreements (each such event referred to
in clauses (a) through (d) above a "Registration Default"), the sole remedy
available to holders of the Old Notes will be the immediate assessment of
Additional Interest as follows: the per annum interest rate on the Old Notes
will increase by 0.25% and the per annum interest rate will increase by an
additional 0.25% for each subsequent 90-day period during which the
Registration Default remains uncured, up to a maximum additional interest rate
of 1.0% per annum. All Additional Interest will be payable to holders of the
Old Notes in cash on each February 1 and August 1, commencing with the first
such date occurring after any such Additional Interest commences to accrue,
until such Registration Default is cured. After the date on which such
Registration Default is cured, the interest rate on the Old Notes will revert
to the original rate per annum.
 
  Holders of Old Notes will be required to make certain representations to the
Company (as described in the Registration Rights Agreements) 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 and to provide
comments on the Shelf Registration Statement within the time periods set forth
in the Registration Rights Agreements in order to have its Old Notes included
in the Shelf Registration Statement and benefit from the provisions regarding
Additional Interest set forth above.
 
  The summary herein of certain provisions of the Registration Rights
Agreements does not purport to be complete and is subject to, and is qualified
in its entirety by, all the provisions of the Registration Rights Agreements,
a copy of which is filed as an exhibit to the Exchange Offer Registration
Statement of which this Prospectus is a part.
 
                                      49
<PAGE>
 
  Following the consummation of the Exchange Offer, holders of the Old Notes
who were eligible to participate in the Exchange Offer but who did not tender
its Old Notes will not have any further registration rights and such Old Notes
will continue to be subject to certain restrictions on transfer. Accordingly,
the liquidity of the market for such Old Notes could be adversely affected.
 
TERMS OF THE EXCHANGE OFFER
 
  Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Old
Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City

of Exchange Notes in exchange for each $1,000 principal amount of outstanding
Old Notes accepted in the Exchange Offer. Holders may tender some or all of
its Old Notes pursuant to the Exchange Offer. However, Old Notes may be
tendered only in integral multiples of $1,000.
 
  The form and terms of the Exchange Notes are the same as the form and terms
of the Old Notes except that (i) the Exchange Notes bear a Series B
designation and a different CUSIP Number from the Old Notes, (ii) the Exchange
Notes have been registered under the Securities Act and hence will not bear
legends restricting the transfer thereof and (iii) the holders of the Exchange
Notes will not be entitled to certain rights under the Registration Rights
Agreements, including the provisions providing for an increase in the interest
rate on the Old Notes in certain circumstances relating to the timing of the
Exchange Offer, all of which rights will terminate when the Exchange Offer is
terminated. The Exchange Notes will evidence the same debt as the Old Notes
and will be entitled to the benefits of the Indentures.
   
  As of the date of this Prospectus, $100,000,000 aggregate principal amount
of Old Senior Notes and $250,000,000 aggregate principal amount of Old Senior
Subordinated Notes were outstanding. The Company has fixed the close of
business on March 4, 1998 as the record date for the Exchange Offer for
purposes of determining the persons to whom this Prospectus and the Letter of
Transmittal will be mailed initially.     
 
  Holders of Old Notes do not have any appraisal or dissenters' rights under
the General Corporation Law of Delaware, or the Indentures in connection with
the Exchange Offer. The Company intends to conduct the Exchange Offer in
accordance with the applicable requirements of the Exchange Act and the rules
and regulations of the Commission thereunder.
 
  The Company shall be deemed to have accepted validly tendered Old Notes
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
for the purpose of receiving the Exchange Notes from the Company.
 
  If any tendered Old Notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, the certificates for any such unaccepted Old Notes will be
returned, without expense, to the tendering holder thereof as promptly as
practicable after the Expiration Date.
 
  Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the
Letter of Transmittal, transfer taxes with respect to the exchange of Old
Notes pursuant to the Exchange Offer. The Company will pay all charges and
expenses, other than transfer taxes in certain circumstances, in connection
with the Exchange Offer. See "--Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
   
  The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
April 6 1998, unless the Company, in its sole discretion, extends the Exchange
Offer, in which case the term "Expiration Date" shall mean the latest date and
time to which the Exchange Offer is extended.     
 
  In order to extend the Exchange Offer, the Company will notify the Exchange
Agent of any extension by oral or written notice and will mail to the
registered holders an announcement thereof, each prior to 9:00 a.m., New York
City time, on the next business day after the previously scheduled expiration
date.
 
                                      50

  The Company reserves the right, in its sole discretion, (i) to delay
accepting any Old Notes, to extend the Exchange Offer or to terminate the
Exchange Offer if any of the conditions set forth below under "--Conditions"
shall not have been satisfied, by giving oral or written notice of such delay,
extension or termination to the Exchange Agent or (ii) to amend the terms of
the Exchange Offer in any manner. Any such delay in acceptance, extension,
termination or amendment will be followed as promptly as practicable by oral
or written notice thereof to the registered holders.
 
INTEREST ON THE EXCHANGE NOTES
 
  The Exchange Notes will bear interest from their date of issuance. Holders
of Old Notes that are accepted for exchange will receive, in cash, accrued
interest thereon to, but not including, the date of issuance of the Exchange
Notes. Such interest will be paid with the first interest payment on the
Exchange Notes on August 1, 1998. Interest on the Old Notes accepted for
exchange will cease to accrue upon issuance of the Exchange Notes.
 
  Interest on the Exchange Notes is payable semi-annually on each February 1
and August 1, commencing on August 1, 1998.
 
PROCEDURES FOR TENDERING
 
  Only a holder of Old Notes may tender such Old Notes in the Exchange Offer.
To tender in the Exchange Offer, a holder must complete, sign and date the
Letter of Transmittal, or a facsimile thereof, have the signatures thereon
guaranteed if required by the Letter of Transmittal or transmit an Agent's
Message in connection with a book-entry transfer, and mail or otherwise
deliver such Letter of Transmittal or such facsimile, together with the Old
Notes and any other required documents, to the Exchange Agent prior to 5:00
p.m., New York City time, on the Expiration Date. To be tendered effectively,
the Old Notes, Letter of Transmittal or an Agent's Message and other required
documents must be completed and received by the Exchange Agent at the address
set forth below under "Exchange Agent" prior to 5:00 p.m., New York City time,
on the Expiration Date. Delivery of the Old Notes may be made by book-entry
transfer in accordance with the procedures described below. Confirmation of
such book-entry transfer must be received by the Exchange Agent prior to the
Expiration Date.
 
  The term "Agent's Message" means a message transmitted by a book-entry
transfer facility to, and received by, the Exchange Agent forming a part of a
confirmation of a book-entry, which states that such book-entry transfer
facility has received an express acknowledgment from the participant in such
book-entry transfer facility tendering the Old Notes that such participant has
received and agrees: (i) to participate in the Automated Tender Option Program
("ATOP"); (ii) to be bound by the terms of the Letter of Transmittal; and
(iii) that the Company may enforce such agreement against such participant.
 
  By executing the Letter of Transmittal, each holder will make to the Company
the representations set forth above in the third paragraph under the heading
"--Purpose and Effect of the Exchange Offer."
 
  The tender by a holder and the acceptance thereof by the Company will
constitute agreement between such holder and the Company in accordance with
the terms and subject to the conditions set forth herein and in the Letter of
Transmittal or Agent's Message.
 
  THE METHOD OF DELIVERY OF OLD NOTES AND THE LETTER OF TRANSMITTAL OR AGENT'S
MESSAGE AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE
ELECTION AND SOLE RISK OF THE HOLDER. AS AN ALTERNATIVE TO DELIVERY BY MAIL,
HOLDERS MAY WISH TO CONSIDER OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT
BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE
SENT TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS,
COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS
FOR SUCH HOLDERS.
 
                                      51
<PAGE>
 
  Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to
tender should contact the registered holder promptly and instruct such
registered holder to tender on such beneficial owner's behalf. See
"Instructions to Registered Holder and/or Book-Entry Transfer Facility
Participant from Beneficial Owner" included with the Letter of Transmittal.
 
  Signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by an Eligible Institution (as defined below)
unless the Old Notes tendered pursuant thereto are tendered (i) by a
registered holder who has not completed the box entitled "Special Registration
Instructions" or "Special Delivery Instructions" on the Letter of Transmittal
or (ii) for the account of an Eligible Institution. 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 guarantee must be by a member firm
of the Medallion System (an "Eligible Institution").
 
  If the Letter of Transmittal is signed by a person other than the registered
holder of any Old Notes listed therein, such Old Notes must be endorsed or
accompanied by a properly completed bond power, signed by such registered
holder as such registered holder's name appears on such Old Notes with the
signature thereon guaranteed by an Eligible Institution.
 
  If the Letter of Transmittal or any Old Notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, offices of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and evidence satisfactory to the
Company of its authority to so act must be submitted with the Letter of
Transmittal.
 
  The Company understands that the Exchange Agent will make a request promptly
after the date of this Prospectus to establish accounts with respect to the
Old Notes at the book-entry transfer facility, The Depository Trust Company
(the "Book-Entry Transfer Facility"), for the purpose of facilitating the
Exchange Offer, and subject to the establishment thereof, any financial
institution that is a participant in the Book-Entry Transfer Facility's system
may make book-entry delivery of Old Notes by causing such Book-Entry Transfer
Facility to transfer such Old Notes into the Exchange Agent's account with
respect to the Old Notes in accordance with the Book-Entry Transfer Facility's
procedures for such transfer. Although delivery of the Old Notes may be
effected through book-entry transfer into the Exchange Agent's account at the
Book-Entry Transfer Facility, unless an Agent's Message is received by the
Exchange Agent in compliance with ATOP, an appropriate Letter of Transmittal
properly completed and duly executed with any required signature guarantee and
all other required documents must in each case be transmitted to and received
or confirmed by the Exchange Agent at its address set forth below on or prior
to the Expiration Date, or, if the guaranteed delivery procedures described
below are complied with, within the time period provided under such
procedures. Delivery of documents to the Book-Entry Transfer Facility does not
constitute delivery to the Exchange Agent.
 
  All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Old Notes and withdrawal of tendered Old
Notes will be determined by the Company in its sole discretion, which
determination will be final and binding. The Company reserves the absolute
right to reject any and all Old Notes not properly tendered or any Old Notes
the Company's acceptance of which would, in the opinion of counsel for the
Company, be unlawful. The Company also reserves the right in its sole
discretion to waive any defects, irregularities or conditions of tender as to
particular Old Notes. The Company's interpretation of the terms and conditions
of the Exchange Offer (including the instructions in the Letter of
Transmittal) will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders of Old Notes must be
cured within such time as the Company shall determine. 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 such notification. Tenders of
Old Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived. Any Old Notes received by the
Exchange Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering holders, unless otherwise provided in the Letter of
Transmittal, as soon as practicable following the Expiration Date.

GUARANTEED DELIVERY PROCEDURES
 
  Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available, (ii) who cannot deliver their Old Notes, the Letter of
Transmittal or any other required documents to the Exchange Agent or (iii) who
cannot complete the procedures for book-entry transfer, prior to the
Expiration Date, may effect a tender if:
 
    (a) the tender is made through an Eligible Institution;
 
    (b) prior to the Expiration Date, the Exchange Agent receives from such
  Eligible Institution a properly completed and duly executed Notice of
  Guaranteed Delivery (by facsimile transmission, mail or hand delivery)
  setting forth the name and address of the holder, the certificate number(s)
  of such Old Notes and the principal amount of Old Notes tendered, stating
  that the tender is being made thereby and guaranteeing that, within five
  New York Stock Exchange trading days after the Expiration Date, the Letter
  of Transmittal (or facsimile thereof) together with the certificate(s)
  representing the Old Notes (or a confirmation of book-entry transfer of
  such Old Notes into the Exchange Agent's account at the Book-Entry Transfer
  Facility), and any other documents required by the Letter of Transmittal
  will be deposited by the Eligible Institution with the Exchange Agent; and
 
    (c) such properly completed and executed Letter of Transmittal (of
  facsimile thereof), as well as the certificate(s) representing all tendered
  Old Notes in proper form for transfer (or a confirmation of book-entry
  transfer of such Old Notes into the Exchange Agent's account at the Book-
  Entry Transfer Facility), and all other documents required by the Letter of
  Transmittal are received by the Exchange Agent upon five New York Stock
  Exchange trading days after the Expiration Date.
 
  Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Old Notes according to the guaranteed
delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
  Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the Expiration Date.
 
  To withdraw a tender of Old Notes in the Exchange Offer, a telegram, telex,
letter or facsimile transmission notice of withdrawal must be received by the
Exchange Agent at its address set forth herein 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(s) and principal amount of such Old Notes, or, in the case
of Old Notes transferred by book-entry transfer, the name and number of the
account at the Book-Entry Transfer Facility to be credited), (iii) be signed
by the holder in the same manner as the original signature on the Letter of
Transmittal by which such Old Notes were tendered (including any required
signature guarantees) or be accompanied by documents of transfer sufficient to
have the Trustee with respect to the Old Notes 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 purposes of
the Exchange Offer and no Exchange Notes will be issued with respect thereto
unless the Old Notes so withdrawn are validly retendered. Any Old Notes which
have been tendered but which are not accepted for exchange 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 one of the procedures
described above under "--Procedures for Tendering" at any time prior to the
Expiration Date.

before the acceptance of such Old Notes, if:
 
    (a) any action or proceeding is instituted or threatened in any court or
  by or before any governmental agency with respect to the Exchange Offer

  DELIVERY TO AN ADDRESS OTHER THAN SET FORTH ABOVE WILL NOT CONSTITUTE A
VALID DELIVERY.
 
FEES AND EXPENSES
 
  The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, telecopy, telephone or in person by officers and
regular employees of the Company and its affiliates.
 
  The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers, or others
soliciting acceptances of the Exchange Offer. The Company, however, will pay
the Exchange Agent reasonable and customary fees for its services and will
reimburse it for its reasonable out-of pocket expenses in connection

                                      54
<PAGE>
 
  The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Company. Such expenses include fees and expenses of the
Exchange Agent and Trustee, accounting and legal fees and printing costs,
among others.
 
ACCOUNTING TREATMENT
 
  The Exchange Notes will be recorded at the same carrying value as the Old
Notes, which is face value, as reflected in the Company's accounting records
on the date of exchange. Accordingly, no gain or loss for accounting purposes
will be recognized by the Company. The expenses of the Exchange Offer will be
expensed over the term of the Exchange Notes.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
  The Old Notes that are not exchanged for Exchange Notes pursuant to the
Exchange Offer will remain restricted securities. Accordingly, such Old Notes
may be resold only (i) to the Company (upon redemption thereof or otherwise),
(ii) so long as the Old Notes are eligible for resale pursuant to Rule 144A,
to a person inside the United States whom the seller reasonably believes is a
qualified institutional buyer within the meaning of Rule 144A under the
Securities Act in a transaction meeting the requirements of Rule 144A, in
accordance with Rule 144 under the Securities Act, or pursuant to another
exemption from the registration requirements of the Securities Act (and based
upon an opinion of counsel reasonably acceptable to the Company), (iii)
outside the United States to a foreign person in a transaction meeting the
requirements of Rule 904 under the Securities Act, or (iv) pursuant to an
effective registration statement under the Securities Act, in each case in
accordance with any applicable securities laws of any state of the United
States.
 
RESALE OF THE EXCHANGE NOTES
 
  With respect to resales of Exchange Notes, based on interpretations by the
staff of the Commission set forth in no-action letters issued to third
parties, the Company believes that a holder or other person who receives
Exchange Notes, whether or not such person is the holder (other than a person
that is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act) who receives Exchange Notes in exchange for Old Notes in the
ordinary course of business and who is not participating, does not intend to
participate, and has no arrangement or understanding with any person to
participate, in the distribution of the Exchange Notes, will be allowed to
resell the Exchange Notes to the public without further registration under the
Securities Act and without delivering to the purchasers of the Exchange Notes
a prospectus that satisfies the requirements of Section 10 of the Securities
Act. However, if any holder acquires Exchange Notes in the Exchange Offer for
the purpose of distributing or participating in a distribution of the Exchange
Notes, such holder cannot rely on the position of the staff of the Commission
enunciated in such no-action letters or any similar interpretive letters, and
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction, unless an exemption
from registration is otherwise available. Further, each Participating Broker-
Dealer that receives Exchange 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 Exchange Notes.
 
  As contemplated by these no-action letters and the Registration Rights
Agreements, each holder accepting the Exchange Offer is required to represent
to the Company in the Letter of Transmittal that (i) the Exchange Notes are to
be acquired by the holder or the person receiving such Exchange Notes, whether
or not such person is the holder, in the ordinary course of business, (ii) the
holder or any such other person (other than a broker-dealer referred to in the
next sentence) is not engaging and does not intend to engage, in the
distribution of the Exchange Notes, (iii) the holder or any such other person
has no arrangement or understanding with any person to participate in the
distribution of the Exchange Notes, (iv) neither the holder nor any such other
person is an "affiliate" of the Company within the meaning of Rule 405 under
the Securities Act, and (v) the holder or any such other person acknowledges
that if such holder or other person participates in the Exchange Offer for the
 
                                      55
<PAGE>
 
purpose of distributing the Exchange Notes it must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale of the Exchange Notes and cannot rely on those no-
action letters. As indicated above, each Participating Broker-Dealer that
receives Exchange Notes for its own account in exchange for Old Notes must
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Notes. For a description of the procedures for such resales by
Participating Broker-Dealers, see "Plan of Distribution."

                           DESCRIPTION OF THE NOTES
 
GENERAL
 
  The Senior Exchange Notes will be issued under the Senior Notes Indenture.
The Senior Subordinated Exchange Notes will be issued under the Senior
Subordinated Notes Indenture. The Exchange Notes are subject to all such
terms, and Holders of Exchange Notes are referred to the Indentures and the
Trust Indenture Act for a statement thereof. The form and terms of the
Exchange Notes are the same as the form and terms of the Old Notes (which they
replace) except that (i) the Exchange Notes bear a Series B designation and a
different CUSIP Number from the Old Notes, (ii) the Exchange Notes have been
registered under the Securities Act and, therefore, will not bear legends
restricting the transfer thereof, and (iii) the holders of Exchange Notes will
not be entitled to certain rights under the Registration Rights Agreement,
including the provisions providing for an increase in the interest rate on the
Old Notes in certain circumstances relating to the timing of the Exchange
Offer, which rights will terminate when the Exchange Offer is consummated. A
copy of the Indentures and the Registration Rights Agreements described below
have been filed as exhibits to the Exchange Offer Registration Statement of
which this Prospectus forms a part.
 
  The following summary of certain provisions of the Indentures and the
Registration Rights Agreements does not purport to be complete and is
qualified in its entirety by reference to the Indentures and the Registration
Rights Agreements, including the definitions therein of certain terms used
below. The definitions of certain terms used in the following summary are set
forth below under "--Certain Definitions" or are otherwise defined in the
Indentures. Any reference to a "Trustee" means the Senior Note Trustee or the
Senior Subordinated Note Trustee, as the context may require. Unless otherwise
specifically indicated, all references in this section to the "Company" are to
NIC and not to any of its subsidiaries. The Old Senior Notes and Senior
Exchange Notes are sometimes collectively referred to herein as the "Senior
Notes," the Old Senior Subordinated Notes and the Senior Subordinated Exchange
Notes are sometimes collectively referred to herein as the "Senior
Subordinated Notes" and the Senior Notes and Senior Subordinated Notes are
sometimes collectively referred to herein as the "Notes."
 
  The Senior Notes are general unsecured obligations of the Company, limited
to $100 million aggregate principal amount, and rank pari passu in right of
payment with all existing and future unsubordinated Indebtedness of the
Company and senior in right of payment to all existing and future subordinated
Indebtedness of the Company. The Senior Notes are effectively subordinated to
all secured Indebtedness of the Company, if any. The Senior Notes mature on
February 1, 2003 and bear interest at the rate per annum of 7%. Interest will
be payable semiannually (to holders of record of Senior Notes at the close of
business on the January 15 or July 15 immediately preceding the interest
payment date) on February 1 and August 1 of each year, respectively,
commencing August 1, 1998. Interest will be computed on the basis of a 360-day
year comprised of twelve 30-day months.
 
  The Senior Subordinated Notes are general unsecured obligations of the
Company, limited to $250 million aggregate principal amount, and are
subordinated in right of payment to all existing and future Senior
Indebtedness of the Company. The Senior Subordinated Notes mature on February
1, 2008 and bear interest at the rate per annum of 8%. Interest will be
payable semiannually (to holders of record of Senior Subordinated Notes at the
close of business on the January 15 or July 15 immediately preceding the
interest payment date) on February 1 and August 1 of each year, respectively,
commencing August 1, 1998. Interest will be computed on the basis of a 360-day
year comprised of twelve 30-day months.
 
  The Notes will not have the benefit of any sinking fund.
 
OPTIONAL REDEMPTION
 
  On or after February 1, 2003, the Senior Subordinated Notes may be redeemed
at any time, in whole or in part, at the option of the Company, on not less
than 20 days' nor more than 60 days' notice, at the redemption

      2006 and thereafter............................................   100.00%
</TABLE>
 
  In addition, prior to February 1, 2001, the Company may, at its option
redeem up to 35% of the principal amount of the Senior Subordinated Notes
originally issued with the net cash proceeds received by the Company from one
or more public offerings of Common Stock of the Company made after the Issue
Date, at a redemption price (expressed as a percentage of the principal
amount) of 108.0% of the principal amount thereof, plus accrued and unpaid
interest to the date fixed for redemption; provided that at least $162.5
million in aggregate principal amount of the Senior Subordinated Notes remains
outstanding immediately after any such redemption (excluding any Notes owned
by the Company or any of its Affiliates). Notice of redemption pursuant to
this paragraph must be mailed to Holders of Senior Subordinated Notes not
later than 60 days following the consummation of such public offering.
 
  Selection of Senior Subordinated Notes for any redemption shall be made by
the Trustee under the Senior Subordinated Note Indenture in accordance with
the rules of any national securities exchange on which the Senior Subordinated
Notes may be listed or if the Senior Subordinated Notes are not so listed, pro
rata or by lot or in such other manner as the Senior Subordinated Note Trustee
shall deem appropriate and fair. Senior Subordinated Notes in denominations
larger than $1,000 may be redeemed in part but only in integral multiples of
$1,000. Notice of redemption will be mailed at least 20 days but not more than
60 days before the redemption date to each Holder of Senior Subordinated Notes
to be redeemed at his or her registered address. On and after the redemption
date, interest will cease to accrue on Senior Subordinated Notes or portions
thereof called for redemption.
 
SUBORDINATION OF SENIOR SUBORDINATED NOTES; RANKING
 
  The Company's obligations with respect to the payment of the principal of,
premium, if any, and interest on, and all other obligations in respect of,
each and all of the Senior Subordinated Notes shall be subordinated in right
of payment, to the extent and in the manner provided in the Senior
Subordinated Note Indenture, to the prior payment in full in cash of all
Senior Indebtedness of the Company.
 
  In the event of (i) any insolvency or bankruptcy case or proceeding, (ii)
any receivership, liquidation, dissolution or other winding up of the Company,
whether voluntary or involuntary and whether or not involving insolvency or
bankruptcy or (iii) any assignment for the benefit of the creditors or any
other marshaling of assets and liabilities of the Company, then and in any
such event specified in (i), (ii) or (iii) above, the holders of Senior
Indebtedness shall be entitled to receive payment in full in cash of all
amounts due or to become due on or in respect of all Senior Indebtedness
before the Holders of the Senior Subordinated Notes are entitled to receive
any Note Payment (as defined below), and in any such event any Note Payment to
which the Holders of the Senior Subordinated Notes or the Senior Subordinated
Note Trustee on their behalf would be entitled, but for the subordination
provisions of the Senior Subordinated Note Indenture, shall be made by the
Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent
or other Person making such payment or distribution, directly to the holders
of the Senior Indebtedness (pro rata to such holders on the basis of the
respective amounts of Senior Indebtedness held by such holders) or their
respective trustee, agent or other representative under any agreement or
indenture pursuant to which any such Senior Indebtedness may have been issued,
as their respective interests may appear, to the extent necessary to pay all
such Senior Indebtedness in full, in cash, after giving effect to any
concurrent payment, distribution or provision therefor to or for the holders
of such Senior Indebtedness.
 
                                      58
<PAGE>
 
  In the event that, notwithstanding the foregoing provision prohibiting such
Note Payment, any Note Payment shall be received by the Senior Subordinated
Note Trustee or any Holder of Senior Subordinated Notes at a time when such
Note Payment is prohibited as described in the preceding paragraph and before
all obligations in respect of Senior Indebtedness are paid in full in cash,
such Note Payment shall be received and held in trust for the benefit of, and
shall be paid over or delivered to, the holders of Senior Indebtedness (pro
rata to such holders on the basis of the respective amounts of Senior
Indebtedness held by such holders) or their respective trustee, agent or other
representative under any agreement or indenture pursuant to which any of such
Senior Indebtedness may have been issued, as their respective interests may
appear, for application to the payment of Senior Indebtedness remaining unpaid
until all such Senior Indebtedness has been paid in full in cash after giving
effect to any concurrent payment, distribution or provision therefor to or for
the account of the holders of such Senior Indebtedness.
 
  No direct or indirect payment, deposit or distribution of any kind or
character, whether in cash, property or securities (including any payment made
to Holders of the Senior Subordinated Notes under the terms of Indebtedness
subordinated to the Senior Subordinated Notes, but excluding any payment or
distribution of Permitted Junior Securities) by or on behalf of the Company of
principal of, premium, if any, or interest on, or any other obligation in
respect of, the Senior Subordinated Notes whether pursuant to the terms of the
Senior Subordinated Notes, upon acceleration, by way of repurchase,
redemption, defeasance or otherwise (all such payments, deposits or
distributions being referred to herein, individually and collectively, as a
"Note Payment"), shall be made if, at the time of such Note Payment, there
exists a default (a "Payment Default") in the payment when due of all or any
portion of the obligations under or in respect of any Designated Senior
Indebtedness, whether at maturity, on account of mandatory redemption or
prepayment, acceleration or otherwise, and such Payment Default shall not have
been cured or waived. In addition, during the continuance of any default or
event of default (other than a Payment Default) with respect to any Designated
Senior Indebtedness pursuant to which the maturity thereof may be accelerated
immediately without the giving of any notice (except such notice as may be
required to effect such acceleration) or the expiration of any applicable
grace periods, no Note Payment may be made by or on behalf of the Company for
a period (a "Payment Blockage Period") commencing upon the receipt by the
Company and the Senior Subordinated Note Trustee of written notice of such
default or event of default from the holder or holders of such Designated
Senior Indebtedness or any trustee, agent or other representative acting on
behalf of the holder or holders of such Designated Senior Indebtedness
specifying an election to effect a Payment Blockage Period (a "Payment
Blockage Notice") and ending 179 days thereafter (or earlier if such Payment
Blockage Period is terminated (i) by written notice to the Senior Subordinated
Note Trustee and the Company from the holder or holders of such Designated
Senior Indebtedness or any trustee, agent or other representative acting on
behalf of the holder or holders of such Designated Senior Indebtedness, (ii)
by discharge or repayment in full in cash of such Designated Senior
Indebtedness or (iii) because the default or event of default giving rise to
such Payment Blockage Notice has been cured, waived or ceased to exist).
Subject to the provisions of the first sentence of this paragraph, the Company
may resume payments on the Senior Subordinated Notes after such Payment
Blockage Period.
 
  Not more than one Payment Blockage Period may be commenced with respect to
the Senior Subordinated Notes during any period of 360 consecutive days,
unless at least 180 consecutive days shall have elapsed during which time no
payment blockage was in effect. No default or event of default that existed or
was continuing on the date of commencement of any Payment Blockage Period with
respect to the Designated Senior Indebtedness initiating such Payment Blockage
Period 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
Indebtedness or any trustee, agent or other representative acting on behalf of
the holder or holders of such Designated Senior Indebtedness, whether or not
within a period of 360 consecutive days, unless such default or event of
default has been cured or waived for a period of not less than 90 consecutive
days.
 
  In the event that, notwithstanding the foregoing, any Note Payment shall be
received by the Senior Subordinated Note Trustee or any Holder when such Note
Payment is prohibited by the second preceding paragraph, such payment shall be
held in trust for the benefit of, and shall be paid over or delivered to, the
holders of Designated Senior Indebtedness or any trustee, agent or other
representative under any agreement or
 
                                      59
<PAGE>
 
indenture pursuant to which any such Designated Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that, upon notice from the Senior Subordinated Note Trustee to the holders of
Designated Senior Indebtedness that such prohibited Note Payment has been
made, the holders of the Designated Senior Indebtedness (or their trustee,
agent or other representative) notify the Senior Subordinated Note Trustee in
writing of the amounts then due and owing on the Designated Senior
Indebtedness, if any, and only the amount specified in such notice to the
Senior Subordinated Note Trustee shall be paid to or for the account of the
holders of Designated Senior Indebtedness.
 
  The failure to make any payment or distribution for or on account of the
Senior Subordinated Notes by reason of the provisions of the Senior
Subordinated Note Indenture described under this section will not be construed
as preventing the occurrence of an Event of Default described in clause (a),
(b) or (c) of the first paragraph under "--Events of Default."
 
  If the Company fails to make any payment on the Senior Subordinated Notes
when due or within any applicable grace period, whether or not such failure is
on account of the subordination provisions referred to above, such failure
would constitute an Event of Default under the Senior Subordinated Note
Indenture and would enable the Holders to accelerate the maturity of the
Senior Subordinated Notes. See "--Events of Default."
 
  By reason of such subordination, in the event of liquidation or insolvency,
creditors of the Company who are not holders of Senior Indebtedness of the
Company (other than the Holders of the Senior Subordinated Notes or other
equally subordinated obligations) may recover less, ratably, than the holders
of Senior Indebtedness of the Company and may recover more, ratably, than the
Holders of the Senior Subordinated Notes.
 
  At October 31, 1997, on a pro forma basis after giving effect to the Initial
Offerings, the Company would have had approximately $100.0 million of
Indebtedness outstanding which would constitute Senior Indebtedness of the
Company. In addition, the Senior Notes will constitute Senior Indebtedness for
purposes of the Senior Subordinated Note Indenture. Although the Senior
Subordinated Note Indenture will restrict, but not prohibit, the incurrence of
Senior Indebtedness of the Company and other Indebtedness by the Company and
its Subsidiaries, the incurrence of significant amounts of additional
Indebtedness could have an adverse impact on the Company's ability to service
its Indebtedness, including the Senior Subordinated Notes. Moreover, the
Senior Subordinated Note Indenture does not impose any limitation on the
incurrence by the Company or by any Subsidiary of the Company of liabilities
that are not Indebtedness under the Senior Subordinated Note Indenture.
 
  At October 31, 1997, on a pro forma basis after giving effect to the Initial
Offerings, there would have been no Indebtedness of the Company outstanding
which would rank pari passu with the Senior Subordinated Notes and no
Indebtedness outstanding that would rank subordinated to the Senior
Subordinated Notes.
 
  The Notes are effectively subordinated to all existing and future
liabilities (including liabilities owed to trade creditors) of the
Subsidiaries of the Company to the extent of the assets of each Subsidiary of
the Company. Any right of the Company to participate in any distribution of
the assets of its Subsidiaries upon the liquidation, reorganization or
insolvency thereof (and the consequent right of the Holders to benefit from
those assets) will be subject to the claims of creditors (including trade
creditors) of such Subsidiary, except to the extent that claims of the Company
itself as a creditor of such Subsidiary may be recognized, in which case the
claims of the Company would still be subordinate to any security interest in
the assets of such Subsidiary and any Indebtedness of such Subsidiary senior
to that held by the Company.
 
  At the date of this Prospectus, the Notes would be solely the obligation of
the Company, and no Subsidiary of the Company would be obligated to the
Holders or obligated or required to pay any amounts due pursuant to the Notes
or make funds available therefor in the form of dividends or advances to the
Company. At October 31, 1997, on a pro forma basis after giving effect to the
Initial Offerings, the Subsidiaries of the Company had other liabilities under
generally accepted accounting principles (including trade payables) to third
parties of approximately $4,431 million. Such Indebtedness includes various
obligations not reported in the capitalization of the Company, primarily
current liabilities (other than short-term debt).

CERTAIN COVENANTS
 
 Relating Only to the Senior Notes
 
  APPLICATION OF FALL AWAY COVENANTS. After the Senior Notes have been
assigned an Investment Grade rating by both Rating Agencies, the Company will
no longer be subject to the agreements and covenants contained in "Limitation
on Incurrence of Indebtedness," "Limitation on Certain Asset Dispositions,"
"Limitation on Restricted Payments," "Limitation on Preferred Stock of
Restricted Subsidiaries," "Limitation on Transactions with Affiliates,"
"Limitation on Payment Restrictions Affecting Restricted Subsidiaries,"
clauses (i)(A) and (iii) of the first paragraph of "Limitation on
Sale/Leaseback Transactions" and clause (ii) of the first paragraph of
"Merger, Consolidation, Etc." as therein; provided, such provisions shall no
longer have application for any purpose of the Senior Note Indenture.
 
  LIMITATION ON LIENS. The Company will not, and will not cause or permit any
of its Restricted Subsidiaries to, create, incur, assume or suffer to exist
any Liens upon any of their respective properties or assets (including,
without limitation, any asset in the form of the right to receive payments,
fees or other consideration or benefits) whether owned on the Issue Date or
acquired after the Issue Date, other than (i) Liens granted by the Company on
property or assets of the Company securing Indebtedness of the Company that is
permitted by the Senior Note Indenture and that is pari passu with the Senior
Notes; provided, that the Senior Notes are secured on an equal and ratable
basis with such Liens; (ii) Liens granted by the Company on property or assets
of the Company securing Indebtedness of the Company that is permitted by the
Senior Note Indenture and that is subordinated to the Senior Notes, provided
that the Senior Notes are secured by Liens ranking prior to such Liens; (iii)
Permitted Liens; (iv) Liens in respect of Acquired Indebtedness permitted by
the Senior Note Indenture; provided, that the Liens in respect of such
Acquired Indebtedness secured such Acquired Indebtedness at the time of the
incurrence of such Acquired Indebtedness and such Liens and the Acquired
Indebtedness were not incurred by the Company or by the Person being acquired
or from whom the assets were acquired in connection with, or in anticipation
of, the incurrence of such Acquired Indebtedness by the Company, and provided,
further that such Liens in respect of such Acquired Indebtedness do not extend
to or cover any property or assets of the Company or of any Restricted
Subsidiary of the Company other than the property or assets that secured the
Acquired Indebtedness prior to the time such Indebtedness became Acquired
Indebtedness of the Company; (v) Liens granted in connection with any
Qualified Securitization Transaction; (vi) Liens arising from claims of

unless: (i) the Company or the Restricted Subsidiary, as the case may be,
receives consideration for such Asset Disposition at least equal to the fair
market value of the assets sold or disposed of (as determined in good faith by
the Company); (ii) not less than 75% of the consideration for the disposition
consists of cash or readily marketable cash equivalents or the assumption of
Indebtedness (other than non-recourse Indebtedness or any Indebtedness
subordinated to the Senior Notes, in the case of the Senior Note Indenture, or
the Senior Subordinated Notes, in the case of the Senior Subordinated Note
Indenture) of the Company or such Restricted Subsidiary or other obligations
relating to such assets (and release of the Company or such Restricted
Subsidiary from all liability on the Indebtedness or other obligations
assumed); and (iii) all Net Available Proceeds, less any amounts invested or
committed to be invested within 360 days of such Asset Disposition in assets
related to the business of the Company (including capital expenditures or the
Capital Stock of another Person (other than the Company or any Person that is
a Restricted Subsidiary of the Company immediately prior to such investment);
provided, that immediately after giving effect to any such investment (and not
prior thereto) such Person shall be a Restricted Subsidiary of the Company),
are applied, on or prior to the 360th day after such Asset Disposition (unless
and to the extent that the Company shall determine to make an Offer to
Purchase), either to (A) the permanent reduction and prepayment of any
Indebtedness of the Company (other than Indebtedness which is expressly
subordinate to the applicable issue of Notes) then outstanding (including a
permanent reduction of commitments in respect thereof) or (B) the permanent
reduction and repayment of any Indebtedness of any Restricted Subsidiary of
the Company then outstanding (including a permanent reduction of commitments
in respect thereof). The 361st day after such Asset Disposition shall be
deemed to be the "Asset Sale Offer Trigger Date," and the amount of Net
Available Proceeds from Asset Dispositions otherwise subject to the preceding
provisions not so applied or as to which the Company has determined not to so
apply shall be referred to as the "Unutilized Net Available Proceeds." Within
fifteen days after the Asset Sale Offer Trigger Date, the Company shall make
an Offer to Purchase the outstanding applicable issue of Notes at a purchase
price in cash equal to 100% of their principal amount plus any accrued and
unpaid interest thereon to the Purchase Date. Notwithstanding the foregoing,
the Company may defer making any Offer to Purchase outstanding Notes until
there are aggregate Unutilized Net Available Proceeds equal to or in excess of
$25.0 million (at which time, the entire Unutilized Net Available Proceeds,
and not just the amount in excess of $25.0 million, shall be applied as
required pursuant to this paragraph). Pending application of the Unutilized
Net Available Proceeds pursuant to this covenant, such Unutilized Net
Available Proceeds shall be invested in Permitted Investments of the types
described in clauses (i), (ii) and (iii) of the definition of "Permitted
Investments."

  If any Indebtedness of the Company or any of its Restricted Subsidiaries
ranking pari passu with the Senior Notes or the Senior Subordinated Notes , as
the case may be, requires that prepayment of, or an offer to prepay, such
Indebtedness be made with any Net Available Proceeds, the Company may apply
such Net Available Proceeds pro rata (based on the aggregate principal amount
of the Senior Notes or the Senior Subordinated Notes, as the case may be, then
outstanding and the aggregate principal amount (or accreted value, if less) of
all such other Indebtedness then outstanding) to the making of an Offer to
Purchase the Senior Notes and the Senior Subordinated Notes in accordance with
the foregoing provisions and the prepayment or the offer to prepay such pari
passu Indebtedness. Any remaining Net Available Proceeds following the
completion of the required Offer to Purchase may be used by the Company for
any other purpose (subject to the other provisions of the Indentures) and the
amount of Net Available Proceeds then required to be otherwise applied in
accordance with this covenant shall be reset to zero, subject to any
subsequent Asset Disposition. These provisions will not apply to a transaction
consummated in compliance with the provisions of the Indentures described
under "--Merger, Consolidation, Etc." below.
 
  Notwithstanding the foregoing, the provisions of this covenant shall not
apply to any Sale/Leaseback Transaction with respect to the purchase of
tooling and related manufacturing equipment in the ordinary course of business
consistent with past practices.
 
  In the event that the Company makes an Offer to Purchase the Notes, the
Company shall comply with any applicable securities laws and regulations,
including any applicable requirements of Section 14(e) of, and Rule 14e-1
under, the Exchange Act and any violation of the provisions of the Indentures
relating to such Offer to Purchase occurring as a result of such compliance
shall not be deemed an Event of Default or an event that with the passing of
time or giving of notice, or both, would constitute an Event of Default.
 
  The subordination provisions relating to the Senior Subordinated Notes and
the "Limitation on Restricted Payments" covenant in the Senior Note Indenture
will prohibit the Company from repurchasing any tendered Senior Subordinated
Notes upon an Asset Disposition unless and until all of the tendered Senior
Notes are first repurchased. In addition, the Company's ability to repurchase
Senior Notes and Senior Subordinated Notes may be limited by other then-
existing borrowing agreements of the Company and its Restricted Subsidiaries.
There can be no assurance that the Company will be able to obtain such a
consent or a waiver of such limitations. See "--Subordination of Senior
Subordination Notes; Ranking" and "--Certain Covenants--Relating to all
Notes--Limitation on Restricted Payments".
 
  After the Senior Notes have been assigned an Investment Grade rating by both
Rating Agencies, and notwithstanding that the Senior Notes may later cease to
have an Investment Grade rating, the Company will not be subject to the
provisions of this covenant with respect to the Senior Note Indenture;
provided, that no Default has occurred and is continuing at the time the
Senior Notes have been assigned such rating.
 
  LIMITATION ON SALE/LEASEBACK TRANSACTIONS. The Company shall not, and shall
not cause or permit any Restricted Subsidiary to, enter into any
Sale/Leaseback Transaction with respect to any property unless (i) the Company
or such Restricted Subsidiary would be entitled to (A) incur Indebtedness in
an amount equal to the Attributable Indebtedness with respect to such
Sale/Leaseback Transaction pursuant to clause (i) of "--Limitation on
Incurrence of Indebtedness" and (B) create a Lien on such property securing
such Attributable Indebtedness without securing the Senior Notes pursuant to
"--Relating Only to the Senior Notes--Limitation on Liens" and the Senior
Subordinated Notes pursuant to "--Relating Only to the Senior Subordinated
Notes --Limitation on Liens," (ii) the net proceeds received by the Company or
any Restricted Subsidiary in connection with such Sale/Leaseback Transaction
are at least equal to the fair value (as determined by the Board of Directors)
of such property and (iii) the Company applies the proceeds of such
transaction in compliance with "--Limitation on Certain Asset Dispositions."
Notwithstanding the foregoing, the provisions of this covenant shall not
prohibit the Company or any Restricted Subsidiary from entering into any
Sale/Leaseback Transaction with respect to the purchase of tooling and related
manufacturing equipment in the ordinary course of business consistent with
past practices.

Company will not, and will not cause or permit any of its Restricted
Subsidiaries to, directly or indirectly, create or suffer to exist or allow to
become effective any consensual encumbrance or restriction of any kind on the
ability of any such Restricted Subsidiary to (i) pay dividends, in cash or
otherwise, or make other payments or distributions on its Capital Stock or any
other equity interest or participation in, or measured by, its profits, owned
by the Company or by any Restricted Subsidiary of the Company, or make
payments on any Indebtedness owed to the Company or to any Restricted
Subsidiary of the Company; (ii) make loans or advances to the Company or to
any Restricted Subsidiary of the Company; or (iii) transfer any of their
respective property or assets to the Company or to any Restricted Subsidiary
of the Company, except for such encumbrances or restrictions existing under or
by reason of (A) applicable law or regulations; (B) customary provisions
restricting subletting or assignment of any lease governing a leasehold
interest of any Restricted Subsidiary of the Company; (C) Indebtedness or any
other contractual requirements (including pursuant to any corporate governance
documents in the nature of a charter or by-laws) of a Securitization
Subsidiary arising in connection with a Qualified Securitization Transaction,
provided, that any such encumbrances and restrictions apply only to such
Securitization Subsidiary; (D) any agreement in effect on the Issue Date as
any such agreement is in effect on such date; (E) any agreement relating to
any Indebtedness incurred by such Restricted Subsidiary prior to the date on
which such Restricted Subsidiary became a Subsidiary of the Company and
outstanding on such date and not incurred in anticipation or contemplation of
becoming a Subsidiary of the Company, provided, such encumbrance or
restriction shall not apply to any assets of the Company or its Restricted
Subsidiaries other than such Restricted Subsidiary; and (F) the Indentures.
 
  After the Senior Notes have been assigned an Investment Grade rating by both
Rating Agencies, and notwithstanding that the Senior Notes may later cease to
have an Investment Grade rating, the Company will not be subject to the
provisions of this covenant with respect to the Senior Note Indenture;
provided, that no Default has occurred and is continuing at the time the
Senior Notes have been assigned such rating.
 
  LIMITATION ON TRANSACTIONS WITH AFFILIATES. The Company will not, and will
not cause or permit any of its Restricted Subsidiaries to (a) sell, lease,
transfer or otherwise dispose of any of its property or assets to, (b)
purchase any property or assets from, (c) make any Investment in, or (d) enter
into or amend or extend any contract, agreement or understanding with or for
the benefit of, any Affiliate of the Company or of any Subsidiary (an
"Affiliate Transaction"), other than Affiliate Transactions that are on terms
that are fair and reasonable to the Company or such Restricted Subsidiary of
the Company and that are no less favorable to the Company or such Restricted
Subsidiary of the Company than those that could be obtained in a comparable
arm's length transaction by the Company or such Restricted Subsidiary of the
Company from an unaffiliated party; provided, that if the Company or any
Restricted Subsidiary of the Company enters into an Affiliate Transaction or
series of Affiliate Transactions involving or having an aggregate value of
more than $20.0 million, a majority of the disinterested members of the Board
of Directors of the Company or a committee thereof shall, prior to the
consummation of such Affiliate Transaction, have determined (as evidenced by a
resolution thereof) that such Affiliate Transaction meets the foregoing
standard. The foregoing restrictions shall not apply to (a) any transaction
between Restricted Subsidiaries of the Company, or between the Company and any
Restricted Subsidiary of the Company if such transaction is not otherwise
prohibited by the terms of the Indentures, (b) transactions entered into
pursuant to the terms of the Master Intercompany Agreement and the Tax
Allocation Agreement, (c) transactions entered into in the ordinary course of
business, (d) Qualified Securitization Transactions, (e) reasonable fees and
compensation paid to and advances of expenses to and indemnity provided on
behalf of officers, directors, employees or consultants of the Company or any
Subsidiary as determined in good faith by the Company's Board of Directors or
senior management; (f) any agreement as in effect as of the Issue Date or any
amendment thereto or any transaction contemplated thereby (including pursuant
to any
 
                                      68
<PAGE>
 
amendment thereto) or in any replacement agreement thereto so long as any such
management or replacement agreement is not more disadvantageous to the Holders
in any material respect than the original agreement as in effect on the Issue
Date; (g) Restricted Payments permitted by the Indenture; (h) loans or
advances to employees or consultants in the ordinary course of business and
consistent with past practices in an aggregate amount outstanding at any time
not to exceed $10.0 million; (i) joint venture partners or purchasers or
sellers of goods or services, in each case in the ordinary course of business
(including, without limitation, pursuant to joint venture agreements) and
otherwise in compliance with the terms of the Indenture which are fair to the
Company or its Restricted Subsidiaries, in the reasonable determination of the
senior management of the Company, or are on terms at least as favorable as
might reasonably have been obtained at such time from an unaffiliated party;
and (j) any employment or compensation arrangement entered into by the Company
or any of its Restricted Subsidiaries in the ordinary course of business that
is not otherwise prohibited by the Indenture.
 
  After the Senior Notes have been assigned an Investment Grade rating by both
Rating Agencies, and notwithstanding that the Senior Notes may later cease to
have an Investment Grade rating, the Company will not be subject to the
provisions of this covenant with respect to the Senior Note Indenture;
provided, that no Default has occurred and is continuing at the time the
Senior Notes have been assigned such rating.
 
  LIMITATION ON GUARANTEES BY RESTRICTED SUBSIDIARIES. The Company shall not
cause or permit any of its Restricted Subsidiaries, directly or indirectly, to
guarantee the payment of any Indebtedness of the Company unless such
Restricted Subsidiary of the Company simultaneously executes and delivers a
supplemental indenture to each of the Indentures providing for the guarantee
of payment of the Senior Notes and the Senior Subordinated Notes (each a
"Subsidiary Guarantee") by such Restricted Subsidiary of the Company (a
"Subsidiary Guarantor"); provided, any guarantee by a Subsidiary Guarantor of
such other Indebtedness (A) (1) (X) is unsecured or (Y) is secured and (I) in
the case of any such guarantee of Senior Indebtedness of the Company, the
Subsidiary Guarantee with respect to the Senior Subordinated Note Indenture is
secured equally and ratably with any Liens securing such guarantee, subject to
the provisions set forth under "--Subordination of the Senior Subordinated
Notes; Ranking" above, (II) in the case of any such guarantee of Indebtedness
of the Company ranking pari passu with the Senior Notes or the Senior
Subordinated Notes, as the case may be, the relevant Subsidiary Guarantees are
secured equally and ratably with any Liens securing such guarantee and (III)
in the case of any such guarantee of Indebtedness of the Company subordinated
to the Senior Notes or the Senior Subordinated Notes, as the case may be, the
relevant Subsidiary Guarantees are secured on a basis ranking prior to the
Liens securing such guarantee and (2) (X) in the case of any such guarantee of
Indebtedness of the Company subordinated or junior to the Senior Notes or the
Senior Subordinated Notes, as the case may be (whether pursuant to its terms
or by operation of law), such guarantee is subordinated pursuant to a written
agreement to the relevant Subsidiary Guarantees at least to the same extent
and in the same manner as such other Indebtedness is subordinated to the
Senior Notes or the Senior Subordinated Notes, as the case may be, or (Y) (I)
in the case of any such guarantee of Senior Indebtedness of the Company
incurred in accordance with the Senior Subordinated Note Indenture, the
relevant Subsidiary Guarantee with respect to the Senior Subordinated Note
Indenture is subordinated to Guarantor Senior Indebtedness of such Subsidiary
Guarantor to the same extent and in the same manner as the Senior Subordinated
Notes are subordinated to Senior Indebtedness of the Company or (II) the
relevant Subsidiary Guarantees are not subordinated or junior to any
Indebtedness of such Subsidiary Guarantor; and (B) such Subsidiary Guarantor
waives, and agrees it will not in any manner whatsoever claim or take the
benefit or advantage of, any rights of reimbursement, indemnity or subrogation
or any other rights against the Company or any other Subsidiary of the Company
as a result of any payment by it under such Subsidiary Guarantees.
Notwithstanding the foregoing, any Subsidiary Guarantee shall provide by its
terms that it shall be automatically and unconditionally released and
discharged upon either (A) the unconditional release or discharge of such
Subsidiary Guarantor's guarantees of all other Indebtedness of the Company
(other than a release resulting from payment under such Subsidiary Guarantor's
guarantees) or (B) any sale, exchange or transfer, to any Person not an
Affiliate of the Company, of all (but not less than all) of the Capital Stock
of such Subsidiary Guarantor, or all or substantially all of the assets of
such Subsidiary Guarantor, pursuant to a transaction which is in compliance
with all of the terms of the relevant Indenture.
 
                                      69

  CHANGE OF CONTROL. Upon the occurrence of a Change of Control (the date of
each such occurrence being the "Change of Control Date"), the Company will
notify the Holders in writing of such occurrence and will commence an Offer to
Purchase (the "Change of Control Offer") all Senior Notes and Senior
Subordinated Notes then outstanding, in each case, at a purchase price equal
to 101% of the principal amount thereof, plus accrued and unpaid interest, if
any, to the Purchase Date. Notice of a Change of Control will be mailed by the
Company to the Holders not more than 30 days after any Change of Control Date.
 
  None of the provisions relating to a purchase upon a Change of Control are
waivable by the Board of Directors of the Company. The Company could, in the
future, enter into certain transactions, including certain recapitalizations
of the Company, that would not constitute a Change of Control with respect to
the Change of Control purchase feature of the Senior Notes and Senior
Subordinated Notes, but would increase the amount of Indebtedness outstanding
at such time. If a Change of Control were to occur, there can be no assurance
that the Company would have sufficient funds to pay the redemption price for
all Notes that the Company is required to redeem. In the event that the
Company were required to purchase outstanding Notes pursuant to a Change of
Control Offer, the Company expects that it would need to seek third-party
financing to the extent it does not have available funds to meet its purchase
obligations. However, there can be no assurance that the Company would be able
to obtain such financing.
 
  With respect to the disposition of property or assets, the phrase "all or
substantially all" as used in the Indentures (including as set forth under "--
Merger, Consolidation, Etc." below) varies according to the facts and
circumstances of the subject transaction, has no clearly established meaning
under New York law (which governs the Indentures) and is subject to judicial
interpretation. Accordingly, in certain circumstances there may be a degree of
uncertainty in ascertaining whether a particular transaction would involve a
disposition of "all or substantially all" of the property or assets of a
Person and therefore it may be unclear as to whether a Change of Control has
occurred and whether the Holders are subject to a Change of Control Offer.
 
  The subordination provisions relating to the Senior Subordinated Notes and
the "Limitation on Restricted Payments" covenant in the Senior Note Indenture
will prohibit the Company from repurchasing any tendered Senior Subordinated
Notes upon a Change of Control unless and until all of the tendered Senior
Notes are first repurchased. In addition, the Company's ability to repurchase
Senior Notes and Senior Subordinated Notes may be limited by other then-
existing borrowing agreements of the Company and its Subsidiaries. There can
be no assurance that the Company will be able to obtain such a consent or a
waiver of such limitations. See "--Subordination of Senior Subordination
Notes; Ranking" and "--Certain Covenants--Relating to all Notes--Limitation on
Restricted Payments".
 
  If an offer is made to redeem Senior Notes and Senior Subordinated Notes as
a result of a Change of Control, the Company will comply with all tender offer
rules under state and Federal securities laws, including, but not limited to,
Section 14(e) under the Exchange Act and Rule 14e-1 thereunder, to the extent
applicable to such offer.
 
  The Change of Control redemption feature of the Senior Notes and the Senior
Subordinated Notes may in certain circumstances make more difficult or
discourage a takeover of the Company and, thus, the removal of incumbent
management.
 
  REPORTS. So long as any Note is outstanding, the Company will file with the
Commission and, within 15 days after it files them with the Commission, file
with the Trustees and mail or cause the Trustees to mail to the Holders at
their addresses as set forth in the registers of the Notes, copies of the
annual reports and of the information, documents and other reports which the
Company is required to file with the Commission pursuant to Section 13 or
15(d) of the Exchange Act or which the Company would be required to file with
the Commission if the Company then had a class of securities registered under
the Exchange Act. In addition, the Company shall cause its annual report to
stockholders and any quarterly or other financial reports furnished to its
stockholders generally to be filed with the Trustees and mailed, no later than
the date such materials are mailed or made available to the Company's
stockholders, to the Holders at their addresses as set forth in the registers
of Notes.

  MERGER, CONSOLIDATION, ETC. The Company will not, in a single transaction or
series of related transactions, consolidate or merge with or into, or sell,
assign, transfer, lease, convey or otherwise dispose of (and the Company will
not cause or permit any of its Restricted Subsidiaries to sell, assign,
transfer, lease, convey or otherwise dispose of) all or substantially all of
the Company's and its Restricted Subsidiaries' assets (determined on a
consolidated basis for the Company and its Restricted Subsidiaries) to any
Person or adopt a Plan of Liquidation unless: (i) either (1) the Company shall
be the surviving or continuing corporation or (2) the Person (if other than
the Company) formed by such consolidation or into which the Company is merged
or the Person which acquires by conveyance, transfer or lease the properties
and assets of the Company and its Restricted Subsidiaries substantially as an
entirety or in the case of a Plan of Liquidation, or Person to which assets of
the Company and its Restricted Subsidiaries have been transferred (x) shall be
a corporation, limited liability company or partnership organized and validly
existing under the laws of the United States or any State thereof or the
District of Columbia and (y) shall expressly assume, by supplemental indenture
(in form and substance satisfactory to each Trustee), executed and delivered
to each Trustee, the due and punctual payment of the principal of, and
premium, if any, and interest on all of the Notes and the performance of every
covenant of the Notes and the Indentures on the part of the Company to be
performed or observed; (ii) immediately after giving effect to such
transaction and the assumption contemplated by clause (i)(2)(y) above
(including giving effect to any Indebtedness and Acquired Indebtedness
incurred or anticipated to be incurred in connection with or in respect of
such transaction), the Company (in the case of clause (1) of the foregoing
clause (i)) or such Person (in the case of clause (2) thereof) could incur at
least $1.00 of additional Indebtedness pursuant to clause (i) of "--Limitation
on Incurrence of Indebtedness"; (iii) immediately before and after giving
effect to such transaction and the assumption contemplated by clause (i)(2)(y)
above (including giving effect to any Indebtedness and Acquired Indebtedness
incurred or anticipated to be incurred in connection with or in respect of the
transaction) no Default and no Event of Default shall have occurred or be
continuing (subject, in the case of the Senior Notes, to the applicability of
the covenant described under "Certain Covenants--Relating Only to the Senior
Notes--Application of Fall Away Covenants"); and (iv) the Company or such
Person shall have delivered to the Trustees (A) an Officers' Certificate and
an Opinion of Counsel, each stating that such consolidation, merger,
conveyance, transfer or lease or Plan of Liquidation and, if a supplemental
indenture is required in connection with such transaction, such supplemental
indenture, comply with this provision of the applicable Indenture and that all
conditions precedent in the applicable Indenture relating to such transaction
have been satisfied and (B) a certificate from the Company's independent
certified public accountants stating that the Company has made the
calculations required by clause (ii) above in accordance with the terms of the
applicable Indenture. Notwithstanding the foregoing, (x) a Restricted
Subsidiary of the Company may consolidate with, or merge with or into, or
sell, assign, transfer, lease, convey or otherwise dispose of all or
substantially all of its assets to, the Company or another Restricted
Subsidiary of the Company without complying with clause (ii) of the above, (y)
a series of transactions involving the sale of Receivables or interests
therein by a Securitization Subsidiary in connection with a Qualified
Securitization Transaction shall not be deemed to be the sale of all or
substantially all of the Company's assets to the extent such transactions are
consummated in the ordinary course of business and (z) the provisions of
clause (i) above shall not prohibit the Company or any Restricted Subsidiary
from selling, assigning, transferring, leasing, conveying or otherwise
disposing of all or substantially all of its assets to a Permitted Joint
Venture in a transaction entered into in compliance with "Certain Covenants--
Relating to All the Notes--Limitation on Restricted Payments."
 
  For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of transactions) of all or
substantially all of the properties or assets of one or more Restricted
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.
 
  Upon any such consolidation, merger, conveyance, lease or transfer in
accordance with the foregoing, the successor Person formed by such
consolidation or into which the Company is merged or to which such conveyance,
lease or transfer is made will succeed to, and be substituted for, and may
exercise every right and power of, the Company under the Indentures with the
same effect as if such successor had been named as the
 
                                      71
<PAGE>
 
Company therein, and thereafter (except in the case of a sale, assignment,
transfer, lease, conveyance or other disposition) the predecessor corporation
will be relieved of all further obligations and covenants under the Indentures
and the Notes.
 
EVENTS OF DEFAULT
 
  The following are Events of Default under the Indentures:
 
    (a) default in the payment of principal of, or premium, if any, on any
  Senior Note or Senior Subordinated Note, as the case may be, when due at
  maturity, upon repurchase, upon acceleration or otherwise, including,
  without limitation, failure of the Company to repurchase any Senior Note or
  Senior Subordinated Note, as the case may be, on the date required
  following a Change of Control (whether or not, in the case of the Senior
  Subordinated Notes, any such payment is prohibited by the provisions
  described under "--Subordination of Senior Subordinated Notes; Ranking"
  above); or
 
    (b) default in the payment of any installment of interest on any Senior
  Note or Senior Subordinated Note, as the case may be, when due and
  continuance of such Default for 30 days or more (whether or not, in the
  case of the Senior Subordinated Notes, such payment is prohibited by the
  provisions described under "--Subordination of Senior Subordinated Notes;
  Ranking" above); or
 
    (c) failure to observe, perform or comply with any of the provisions
  described under "Certain Covenants--Relating to all Notes--Merger,
  Consolidation, Etc." above; or
 
    (d) default (other than a default set forth in clauses (a), (b) and (c)
  above) in the performance of, or breach of, any other covenant or warranty
  of the Company or of any Restricted Subsidiary in the Senior Note Indenture
  or the Senior Subordinated Note Indenture, as the case may be, or in the
  Notes and failure to remedy such default or breach within a period of 30
  days after written notice from the relevant Trustee or the Holders of at
  least 25% in aggregate principal amount of the then outstanding Senior
  Notes or Senior Subordinated Notes, as the case may be; or
 
    (e) default under any mortgage, indenture or instrument under which there
  may be issued or by which there may be secured or evidenced any
  Indebtedness for money borrowed by the Company or any Subsidiary of the
  Company (or the payment of which is guaranteed by the Company or any
  Restricted Subsidiary of the Company), which default results in the
  acceleration of such Indebtedness prior to its express maturity and the
  principal amount of any such Indebtedness, together with the principal
  amount of any other such Indebtedness the maturity of which has been so
  accelerated, aggregates $20.0 million or more and such acceleration has not
  been rescinded or annulled or such Indebtedness discharged in full within
  30 days; or
 
    (f) the entry by a court of competent jurisdiction of one or more
  judgments, orders or decrees against the Company or any Subsidiary of the
  Company or any of their respective property or assets in an aggregate
  amount in excess of $20.0 million, which judgments, orders or decrees have
  not been vacated, discharged, satisfied or stayed pending appeal within 30
  days from the entry thereof and with respect to which legal enforcement
  proceedings have been commenced; or
 
    (g) certain events of bankruptcy, insolvency or reorganization involving
  the Company or any Material Subsidiary of the Company.
 
  If an Event of Default (other than an Event of Default specified in clause
(g) above involving the Company) occurs and is continuing, then and in every
such case the Senior Note Trustee or the Senior Subordinated Note Trustee or
the Holders of not less than 25% in aggregate principal amount of the then
outstanding Senior Notes or Senior Subordinated Notes may, and the relevant
Trustee shall upon the request of Holders of not less than 25% in aggregate
principal amount of the Senior Notes or Senior Subordinated Notes then
outstanding, declare the unpaid principal of, premium, if any, and accrued and
unpaid interest on all the Senior Notes or Senior Subordinated Notes, as the
case may be, then outstanding to be due and payable, by a notice in writing to
the Company (and to the relevant Trustee, if given by Holders) and upon such
declaration such principal amount, premium, if any, and accrued and unpaid
interest will become immediately due and payable, notwithstanding
 
                                      72
<PAGE>
 
anything contained in the relevant Indenture or the Notes to the contrary, but
subject to the provisions limiting payment described in "--Subordination of
Senior Subordinated Notes; Ranking" above. If an Event of Default specified in
clause (g) above involving the Company occurs, all unpaid principal of, and
premium, if any, and accrued and unpaid interest on the Senior Notes and the
Senior Subordinated Notes then outstanding will ipso facto become due and
payable, subject to the prior payment in full of all Senior Indebtedness of
the Company, without any declaration or other act on the part of any Trustee
or any Holder.
 
  No Holder of any Note may enforce either Indenture or the Notes except as
provided in the relevant Indenture. Subject to the provisions of the relevant
Indenture relating to the duties of the Trustee, with respect to each such
Indenture the Trustee is under no obligation to exercise any of its rights or
powers under such Indenture at the request, order or direction of any of the
Holders, unless such Holders have offered to such Trustee reasonable
indemnity. Subject to all provisions of the Indentures and applicable law, the
Holders of a majority in aggregate principal amount of the then outstanding
Senior Notes and Senior Subordinated Notes, as the case may be, have the right
to direct the time, method and place of conducting any proceeding for any
remedy available to the relevant Trustee or exercising any trust or power
conferred on the relevant Trustee. The Trustee may withhold from the relevant
Holders notice of any continuing Default or Event of Default (except a Default
or Event of Default in the payment of principal of or premium, if any, or
interest on the Senior Notes or Senior Subordinated Notes, as the case may be,
or that resulted from the failure of the Company to comply with the provisions
of "--Certain Covenants--Relating to all Notes--Change of Control" or "--
Merger, Consolidation, Etc." above) if it determines that withholding notice
is in their interest. The Holders of a majority in aggregate principal amount
of the Senior Notes then outstanding by notice to the Senior Note Trustee may
rescind an acceleration of such Senior Notes and its consequences if all
existing Events of Default (other than the nonpayment of principal of and
premium, if any, and interest on the Senior Notes which has become due solely
by virtue of such acceleration) have been cured or waived and if the
rescission would not conflict with any judgment or decree. The Holders of a
majority in aggregate principal amount of the Senior Subordinated Notes then
outstanding by notice to the Senior Subordinated Note Indenture Trustee may
rescind an acceleration of such Senior Subordinated Notes and its consequences
if all existing Events of Default (other than the non-payment of principal of
and premium, if any, and interest on the Senior Subordinated Notes which has
become due solely by virtue of such acceleration) have been cured or waived
and if the rescission would not conflict with any judgment or decree. No such
rescission shall affect any subsequent Default or impair any right consequent
thereto.
 
  The Holders of a majority in aggregate principal amount of the Senior Notes
then outstanding may, on behalf of the Holders of all the Senior Notes, waive
any past Default or Event of Default under the Senior Note Indenture and its
consequences, except a Default in the payment of principal of or premium, if
any, or interest on the Senior Notes or in respect of a covenant or provision
of the Senior Note Indenture which cannot be modified or amended without the
consent of all Holders. The Holders of a majority in aggregate principal
amount of the Senior Subordinated Notes then outstanding may on behalf of the
Holders of all the Senior Subordinated Notes, waive any past Default or Event
of Default under the Senior Subordinated Note Indenture and its consequences,
except a Default in the payment of principal of or premium, if any, or
interest on, the Senior Subordinated Notes or in respect of a covenant or
provision of the Senior Subordinated Note Indenture which cannot be modified
or amended without the consent of all Holders.
 
  Under each Indenture, two executive officers of the Company are required to
provide a certificate to the relevant Trustee promptly upon any such officer
obtaining knowledge of any Default or Event of Default (provided that such
officers shall provide such certification at least annually whether or not
they know of any Default or Event of Default) that has occurred and, if
applicable, describe such Default or Event of Default and the status thereof.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
  From time to time, the Company, when authorized by a resolution of its Board
of Directors, and the relevant Trustee, may, without the consent of the
Holders, amend, waive or supplement either Indenture and the Notes
 
                                      73
<PAGE>
 
issued thereunder for certain specified purposes, including, among other
things, curing ambiguities, defects or inconsistencies, qualifying, or
maintaining the qualification of, the relevant Indenture under the TIA, or
making any change that does not adversely affect the rights of any Holder;
provided that the Company has delivered to the relevant Trustee an opinion of
counsel stating that such change does not adversely affect the rights of any
Holder. Other amendments and modifications of an Indenture and the Notes
issued thereunder may be made by the Company, and the relevant Trustee with
the consent of the Holders of not less than a majority of the aggregate
principal amount of the Notes issued under such Indenture then outstanding;
provided that no such amendment or modification may, without the consent of
the Holder of each outstanding Senior Note or Senior Subordinated Note, as the
case may be, affected thereby: (a) change the maturity of the principal of or
any installment of interest on any such Senior Note or Senior Subordinated
Note or alter the optional redemption or repurchase provisions of any such
Senior Note or Senior Subordinated Note or such Indenture in a manner adverse
to the Holders of such Senior Notes or Senior Subordinated Notes, as the case
may be, (b) reduce the principal amount of (or the premium) of any such Senior
Note or Senior Subordinated Note, as the case may be, (c) reduce the rate of
or extend the time for payment of interest on any such Senior Note or Senior
Subordinated Note, as the case may be, (d) change the place or currency of
payment of principal of (or premium) or interest on any such Senior Note or
Senior Subordinated Note, as the case may be, (e) modify any provisions of
such Indenture relating to the waiver of past defaults (other than to add
sections of such Indenture or such Senior Notes or Senior Subordinated Notes
subject thereto or the right of the Holders of Senior Notes and the Senior
Subordinated Notes, as the case may be, outstanding thereunder to institute
suit for the enforcement of any payment on or with respect to any such Senior
Note or Senior Subordinated Note or the modification and amendment of such
Indenture and such Senior Notes or Senior Subordinated Notes (other than to
add sections of such Indenture or such Notes which may not be amended,
supplemented or waived without the consent of each Holder herein affected),
(f) reduce the percentage of the principal amount of outstanding Senior Notes
and Senior Subordinated Notes, as the case may be, necessary for amendment to
or waiver of compliance with any provision of the applicable Indenture or the
Senior Notes and Senior Subordinated Notes, as the case may be, outstanding
thereunder or for waiver of any Default in respect thereof, (g) waive a
default in the payment of principal of, interest on, or redemption payment
with respect to, such Senior Note or Senior Subordinated Note (except a
rescission of acceleration of the relevant Notes by the Holders thereof as
provided in such Indenture and a waiver of the payment default that resulted
from such acceleration), (h) in the case of the Senior Subordinated Note
Indenture, modify the ranking or priority of the Senior Subordinated Notes or
modify the definition of Senior Indebtedness or amend or modify the
subordination provisions of the Senior Subordinated Note Indenture in any
manner adverse to the Holders of Senior Subordinated Notes, (i) in the case of
the Senior Note Indenture, modify the ranking or priority of the Senior Notes,
or (j) modify the provisions relating to any Offer to Purchase required under
the covenants described under "--Certain Covenants--Relating to all the
Notes--Limitation on Certain Asset Dispositions" or "--Certain Covenants--
Relating to all the Notes--Change of Control" in a manner materially adverse
to the Holders of Senior Notes and Senior Subordinated Notes affected thereby.
 
  No amendment or modification of the Senior Subordinated Indenture or the
Senior Subordinated Notes may adversely affect the rights of the holders of
Senior Indebtedness of the Company unless the holders of such Senior
Indebtedness consent to such amendment or modification.
 
DEFEASANCE OR COVENANT DEFEASANCE OF INDENTURES
 
  The Company may, at its option and at any time, terminate the obligations of
the Company with respect to either the Senior Notes or the Senior Subordinated
Notes ("defeasance"). Such defeasance means that the Company shall be deemed
to have paid and discharged the entire Indebtedness represented by the
outstanding Notes so defeased, except for (i) the rights of holders of
outstanding Notes to receive payment in respect of the principal of, premium,
if any, and interest on such Notes when such payments are due, (ii) the
Company's obligations to issue temporary Notes, register the transfer or
exchange of any Notes, replace mutilated, destroyed, lost or stolen Notes and

<PAGE>
 
certain covenants that are set forth in the Indentures, some of which are
described under "--Certain Covenants" above, and any omission to comply with
such obligations shall not constitute a Default or an Event of Default with
respect to the Notes so defeased ("covenant defeasance").
 
  In order to exercise either defeasance or covenant defeasance, (i) the
Company must irrevocably deposit with the relevant Trustee, in trust, for the
benefit of the holders of the Notes to be defeased, cash in United States
dollars, U.S. Government Obligations, or a combination thereof, in such
amounts as will be sufficient, in the opinion of a nationally recognized firm
of independent public accountants, to pay the principal of, premium, if any,
and interest on the outstanding Notes to be defeased to redemption or
maturity; (ii) the Company shall have delivered to the Trustee an opinion of
counsel to the effect that the holders of the outstanding Notes to be defeased
will not recognize income, gain or loss for Federal income tax purposes as a
result of such defeasance or covenant defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if the act of such defeasance or covenant
defeasance had not occurred (in the case of defeasance, such opinion must
refer to and be based upon a ruling of the Internal Revenue Service or a
change in applicable Federal income tax laws); (iii) no Default or Event of
Default under the relevant Indenture shall have occurred and be continuing
immediately after giving effect to such deposit; (iv) such defeasance or
covenant defeasance shall not cause the relevant Trustee to have a conflicting
interest with respect to any securities of the Company; (v) such defeasance or
covenant defeasance shall not result in a breach or violation of, or
constitute a default under, any material agreement or instrument to which the
Company is a party or by which it is bound; (vi) the Company shall have
delivered to the relevant Trustee an opinion of counsel to the effect that (A)
in the case of the Senior Subordinated Notes, the trust funds will not be
subject to any rights of holders of Senior Indebtedness of the Company,
including, without limitation, those arising under the Senior Subordinated
Indenture and (B) after the 91st day following the deposit, the trust funds
will not be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally; and
(vii) the Company shall have delivered to the relevant Trustee an officers'
certificate and an opinion of counsel, each stating that all conditions
precedent under the relevant Indenture to either defeasance or covenant
defeasance, as the case may be, have been complied with. Notwithstanding the
foregoing, the Opinion of Counsel required by clause (ii) above need not be
delivered if at such time all outstanding Senior Notes or Senior Subordinated
Notes, as the case may be, have been irrevocably called for redemption.
 
SATISFACTION AND DISCHARGE
 
  An Indenture will be discharged and will cease to be of further effect
(except as to surviving rights or registration of transfer or exchange of the
Notes issued thereunder, as expressly provided for in such Indenture) as to
all outstanding Notes issued thereunder when (i) either (a) all the Notes
issued thereunder theretofore authenticated and delivered (except lost, stolen
or destroyed Notes issued thereunder which have been replaced or paid and
Notes issued thereunder for whose payment money has theretofore been deposited
in trust or segregated and held in trust by the Company and thereafter repaid
to the Company or discharged from such trust) have been delivered to the
relevant Trustee for cancellation or (b) all Notes issued thereunder not
theretofore delivered to the relevant Trustee for cancellation have become due
and payable and the Company has irrevocably deposited or caused to be
deposited with the relevant Trustee funds in an amount sufficient to pay and
discharge the entire Indebtedness on the Notes issued thereunder not
theretofore delivered to the relevant Trustee for cancellation, for principal
of, premium, if any, and interest on the Notes issued thereunder to the date
of deposit together with irrevocable instructions from the Company directing
the relevant Trustee to apply such funds to the payment thereof at maturity;
(ii) the Company has paid all other sums payable under such Indenture by the
Company; and (iii) the Company has delivered to the relevant Trustee an
officers' certificate and an opinion of counsel stating that all conditions
precedent under such Indenture relating to the satisfaction and discharge of
such Indenture have been complied with.
 
GOVERNING LAW
 
  The Indentures and the Notes will be governed by, and construed in
accordance with, the laws of the State of New York but without giving effect
to applicable principles of conflicts of law to the extent that the
application of the law of another jurisdiction would be required thereby.
 
                                      75
<PAGE>
 
THE TRUSTEES
 
  The Indentures will provide that, except during the continuance of an Event
of Default, the Trustees will perform only such duties as are specifically set
forth in the Indentures. During the existence of an Event of Default, the
relevant Trustee will exercise such rights and powers vested in it by such
Indenture, and use the same degree of care and skill in its exercise as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.
 
  The Indentures and the provisions of the TIA contain certain limitations on
the rights of the Trustees, should it become a creditor of the Company, to
obtain payments of claims in certain cases or to realize on certain property
received in respect of any such claim as security or otherwise. Subject to the
TIA, the Trustees will be permitted to engage in other transactions, provided
that if any Trustee acquires any conflicting interest as described in the TIA,
it must eliminate such conflict or resign.
 
BOOK-ENTRY; DELIVERY AND FORM
 
  The certificates representing the Exchange Notes will be issued in fully
registered form without interest coupons.
 
 The Global Notes
 
  Each of the Senior Exchange Notes and the Senior Subordinated Exchange Notes
issued in the Exchange Offer will initially be represented by a single,
permanent global Note in definitive, fully registered form without interest
coupons (the "Global Notes"). Upon the issuance of the Global Notes, the
Depositary or its custodian will credit, on its internal system, the
respective principal amount of the individual beneficial interests represented
by such Global Note to the accounts of persons who have accounts with such
Depositary. Ownership of beneficial interests in a Global Note will be limited
to persons who have accounts with the Depositary ("participants") or persons
who hold interests through participants. Ownership of beneficial interests in
a Global Note will be shown on, and the transfer of that ownership will be
effected only through, records maintained by the Depositary or its nominee
(with respect to interests of participants) and the records of participants
(with respect to interests of persons other than participants).
 
  So long as the Depositary, or its nominee, is the registered holder of a
Global Note, the Depositary or such nominee, as the case may be, will be
considered the sole owner or holder of the Notes represented by such Global
Note for all purposes under the Indenture and the Notes. No beneficial owner
of an interest in a Global Note will be able to transfer that interest except
in accordance with the procedures provided for under the Depositary's
applicable procedures.
 
  Payments of the principal of, and interest on, the Global Notes will be made
to the Depositary or its nominee, as the case may be, as the registered owner
thereof. None of the Company, the Trustee or any Paying Agent will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the Global Notes
or for maintaining, supervising or reviewing any records relating to such,
beneficial ownership interests.
 
  The Company expects that the Depositary or its nominee, upon receipt of any
payment of principal or interest in respect of a Global Note will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of such Global Note as
shown on the records of the Depositary or its nominee. The Company also
expects that payments by participants to owners of beneficial interests in
such Global Note held through such participants will be governed by standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers registered in the name of nominees for such
customers. Such payments will he the responsibility of such participants.
Transfers between participants in the Depositary will be effected in the
ordinary way in accordance with the Depositary rules and will be settled in
same-day funds.
 
                                      76
<PAGE>
 
  The Depositary has advised the Company that it will take any action
permitted to be taken by a holder of Notes (including the presentation of
Notes for exchange as described below) only at the direction of one or more
participants to whose accounts an interest in the Global Notes is credited and
only in respect of such portion of the aggregate principal amount of Notes as
to which such participant or participants has or have given such direction.
 
  The Depositary has advised the Company as follows: The Depositary is a
limited purpose trust company organized under the laws of the State of New
York, a "banking organization" within the meaning of New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the Uniform Commercial Code and a "Clearing Agency" registered
pursuant to the provisions of Section 17A of the Exchange Act. The Depositary
was created to hold securities for its participants and facilitate the
clearance and settlement of securities transactions between participants
through electronic book-entry changes in accounts of its participants, thereby
eliminating the need for physical movement of certificates. Participants
include securities brokers and dealers, banks, trust companies and clearing
corporations and certain other organizations. Indirect access to the
Depositary system is available to others such as banks, brokers, dealers and
trust companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly ("indirect participants").
 
  Although the Depositary has agreed to the foregoing procedures in order to
facilitate transfers of interests in the Global Notes among participants of
the Depositary it is under no obligation to perform or continue to perform
such procedures, and such procedures may be discontinued at any time. Neither
the Company nor the Trustee will have any responsibility for the performance
by the Depositary or its respective participants or indirect participants of
its respective obligations under the rules and procedures governing its
operations.
 
 Certificated Notes
 
  Global Notes may not be transferred as or exchanged for physical
certificates in registered form without coupons (the "Certificated Notes")
except (i) if the Depositary notifies the Company that it is unwilling or
unable to continue to act as depositary with respect to the Global Notes or
ceases to be a clearing agency registered under the Exchange Act and, in
either case, a successor depositary registered as a clearing agency under the
Exchange Act is not appointed by the Company within 120 days, (ii) at any time
if the Company in its sole discretion determines that the Global Notes (in
whole but not in part) should be exchanged for Certificated Notes or (iii) if
the owner of an interest in the Global Notes requests such Certificated Notes,
following an Event of Default under the Indenture, in a writing delivered
through the Depositary to the Trustee.

(including, without limitation, those related to the adoption of new
accounting standards) realized by the referent Person or any of its Restricted
Subsidiaries during the period for which such determination is made; (v)

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a discussion of certain material United States federal
income tax consequences of the acquisition, ownership and disposition of the
Notes. Unless otherwise stated, this discussion is limited to the tax
consequences to those persons who are original beneficial owners of the Notes
and who hold such Notes as capital assets ("Holders"). This discussion does
not address specific tax consequences that may be relevant to particular
persons (including, for example, financial institutions, broker-dealers,
insurance companies, tax-exempt organizations, estates, trusts, and persons in
special situations, such as those who hold Notes as part of a straddle, hedge,
conversion transaction, or other integrated investment). This discussion also
does not address the tax consequences to Non-U.S. Holders (as defined below)
that are subject to U.S. federal income tax on a net basis on income realized
with respect to a Note because such income is effectively connected with the
conduct of a U.S. trade or business. This discussion does not address the tax
consequences to persons that have a functional currency other than the U.S.
dollar. In addition, this discussion does not address U.S. federal alternative
minimum tax consequences or any aspect of state, local or foreign taxation.
This discussion is based upon the Internal Revenue Code of 1986, as amended
(the "Code"), the Treasury Department regulations promulgated thereunder, and
administrative and judicial interpretations thereof, all as of the date hereof
and all of which are subject to change, possibly on a retroactive basis.
 
  HOLDERS OF THE NOTES ARE URGED TO CONSULT THEIR TAX ADVISORS CONCERNING THE
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO THEM OF ACQUIRING, OWNING AND
DISPOSING OF THE NOTES, AS WELL AS THE APPLICATION OF STATE, LOCAL AND FOREIGN
INCOME AND OTHER TAX LAWS.
 
U.S. FEDERAL INCOME TAXATION OF U.S. HOLDERS
 
 Payments of Interest
 
  In general, interest on a Note will be taxable to a beneficial owner who or
which is, (i) a citizen or resident of the United States; (ii) a corporation
created or organized under the laws of the United States or any State thereof
(including the District of Columbia); or (iii) a person otherwise subject to
U.S. federal income taxation on its worldwide income (a "U.S. Holder") as
ordinary income at the time it is (actually or constructively) received or
accrued, depending on such holder's method of accounting for U.S. federal
income tax purposes.
 
 Disposition of Notes
 
  Upon the sale, exchange, redemption, retirement at maturity or other
disposition of a Note, a U.S. Holder generally will recognize taxable gain or
loss equal to the difference between (i) the sum of cash plus the fair market
value of all other property received on such disposition (except to the extent
such cash or property is attributable to accrued but unpaid interest, which
will be taxable as ordinary income); and (ii) such holder's adjusted tax basis
in the Note. A U.S. Holder's adjusted tax basis in a Note generally will equal
the cost of the Note to such holder, less any principal payments received by
such holder.
 
  Gain or loss recognized on the disposition of a Note generally will be
capital gain or loss. The net amount of such capital gain recognized by an
individual U.S. Holder will be subject to tax at a maximum rate of (i) 28%, if
the Note is held for more than 12 months but not more than 18 months, and (ii)
20%, if the Note is held for more than 18 months.
 
 Exchange Offer
 
  The exchange of Old Notes for Exchange Notes pursuant to the Exchange Offer
will not be treated as an "exchange" for U.S. federal income tax purposes
because the Exchange Notes will not be considered to differ materially in kind
or extent from the Old Notes. As a result, there will be no U.S. federal
income tax consequences to beneficial owners exchanging the Old Notes for the
Exchange Notes pursuant to the Exchange
 
                                      92
<PAGE>
 
Offer. The Company is obligated to pay additional interest to the beneficial
owners of Old Notes under certain circumstances. The Company believes that any
such payments of interest should be treated as subject to an "incidental
contingency" for purposes of the original issue discount rules because the
potential amount of any such interest payments, if required to be made, is
expected to be insignificant relative to the total expected amount of
remaining payments on the Old Notes, and accordingly, if such interest
payments are required to be made, such interest should be taxable to
beneficial owners in the manner described under "Certain Federal Income Tax
Considerations--U.S. Federal Income Taxation of U.S. Holders--Payments of
Interest." It is possible, however, that the Internal Revenue Service ("IRS")
may take a different position, in which case the timing and amount of such
income may be different.
 
U.S. FEDERAL INCOME TAXATION OF NON-U.S. HOLDERS
 
  Under present U.S. federal income tax law and subject to the discussion of
backup withholding below:
 
    (i) payments of principal and interest on the Notes by the Company or any
  agent of the Company to any beneficial owner of a Note that is not a U.S.
  Holder (a "Non-U.S. Holder") generally will not be subject to U.S. federal
  withholding tax, provided that in the case of interest (a) (1) the Non-U.S.
  Holder does not actually or constructively own 10 percent or more of the
  total combined voting power of all classes of stock of the Company entitled
  to vote, (2) the Non-U.S. Holder is not a controlled foreign corporation
  that is related to the Company through stock ownership, (3) the Non-U.S.
  Holder is not a bank described in Section 881(c)(3)(A) of the Code, and (4)
  either (A) the beneficial owner of the Notes certifies to the Company or
  its agent on IRS Form W-8 (or a suitable substitute form), under penalties
  of perjury, that it is not a "U.S. person" (as defined in the Code) and
  provides its name and address, or (B) a securities clearing organization,
  bank or other financial institution that holds customers' securities in the
  ordinary course of its trade or business (a "financial institution") and
  holds the Notes on behalf of the beneficial owner who certifies to the
  Company or its agent under penalties of perjury that such statement has
  been received from the beneficial owner by it or by a financial institution
  between it and the beneficial owner and furnishes the payor with a copy
  thereof (the "Portfolio Interest Exemption") or (b) the Non-U.S. Holder is
  entitled to the benefits of an income tax treaty under which interest on
  the Notes is exempt from U.S. federal withholding tax and provides a
  properly executed IRS Form 1001 claiming the exemption (a "Treaty
  Exemption");
 
    (ii) a Non-U.S. Holder generally will not be subject to U.S. federal
  withholding tax on gain realized on the sale, exchange or other disposition
  of a Note unless (a) the Non-U.S. Holder is an individual who is present in
  the United States for a period or periods aggregating 183 or more days in
  the taxable year of the disposition and certain other conditions are met or
  (b) the Non-U.S. Holder is subject to tax pursuant to the provisions of
  U.S. tax law applicable to certain U.S. expatriates; and
 
    (iii) the exchange of Notes for Exchange Notes pursuant to the Exchange
  Offer will not be treated as an "exchange" for U.S. federal income tax
  purposes because the Exchange Notes will not be considered to differ
  materially in kind or extent from the Notes. As a result, there will be no
  U.S. federal income tax consequences to beneficial owners exchanging the
  Notes for the Exchange Notes pursuant to the Exchange Offer.
 
  The United States Treasury Department recently adopted final regulations
governing federal withholding taxes, information reporting and backup
withholding rules ("Final Regulations") which are generally effective for
payments after December 31, 1998, subject to certain transition rules.
 
  In general, the Final Regulations continue to require that Form W-8 be
furnished to establish eligibility for the Portfolio Interest Exemption;
however, Form W-8 may in some circumstances require additional information not
required on current Form W-8.
 
  The Final Regulations generally require Non-U.S. Holders to execute Form W-
8, rather than Form 1001, to establish eligibility for a Treaty Exemption. For
any periods during which the Notes are not "actively traded," a
 
                                      93
<PAGE>
 
Non-U.S. Holder may be required, in order to claim a Treaty Exemption, to (a)
furnish a valid United States federal taxpayer identification number and (b)
furnish proof of the holder's foreign residency (by furnishing an Internal
Revenue Service certification based on (i) a certification from the
appropriate tax official in the foreign country, or (ii) appropriate
documentary evidence).
 
  Under the Final Regulations, certification on Form W-8 for purposes of the
Portfolio Interest Exemption or a Treaty Exemption will generally remain valid
for 3 years, at which time a new Form W-8 may be required to be executed. In
certain cases, the Final Regulations provide alternative forms of
documentation for purposes of the Portfolio Interest Exemption or a Treaty
Exemption, for example, where the Notes are held by certain foreign
partnerships or certain foreign intermediaries.
 
  EACH NON-U.S. HOLDER SHOULD CONSULT THE HOLDER'S TAX ADVISOR AS TO THE
APPLICATION OF THE FINAL REGULATIONS AND THE PROCEDURES THEREUNDER FOR
ESTABLISHING FOREIGN STATUS FOR PURPOSES OF THE PORTFOLIO INTEREST EXEMPTION
OR A TREATY EXEMPTION.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
  For each calendar year in which the Notes are outstanding, the Company is
required to provide the IRS with certain information, including the beneficial
owner's name, address and taxpayer identification number, the aggregate amount
of interest paid to that beneficial owner during the calendar year and the
amount of tax withheld, if any. This obligation, however, does not apply with
respect to certain payments to U.S. Holders, including corporations, tax-
exempt organizations, qualified pension and profit sharing, trusts and
individual retirement accounts, provided that such holders establish
entitlement to an exemption.
 
  In the event that a U.S. Holder subject to the reporting requirements
described above fails to supply its correct taxpayer identification number in
the manner required by applicable law or underreports its tax liability, the
Company, its agents or paying agents or a broker may be required to "backup"
withhold at a rate of 31% with respect to payments in respect of interest,
principal (and premium, if any) and gross proceeds from dispositions of Notes.
This backup withholding is not an additional tax and may be credited against
the U.S. Holder's U.S. federal income tax liability, provided that the
required information is furnished to the IRS.
 
  Under current Treasury regulations, backup withholding and information
reporting will not apply to payments made by the Company or any agent thereof
(in its capacity as such) to a Non-U.S. Holder of a Note if such holder has
provided the required certification that it is not a U.S. person as set forth
in clause (a)(4) in paragraph (i) under "Certain Federal Income Tax
Considerations--U.S. Federal Income Taxation of Non-U.S. Holders," or has
otherwise established an exemption (provided that neither the Company nor its
agent has actual knowledge that the holder is a U.S. person or that the
conditions of any exemption are not in fact satisfied).
 
  Payment of the proceeds from the sale of a Note to or through a foreign
office of a broker will not be subject to information reporting or backup
withholding. However, if such broker is a U.S. person, a controlled foreign
corporation for U.S. federal income tax purposes or a foreign person 50
percent or more of whose gross income from all sources for the three-year
period ending with the close of its taxable year preceding the payment was
effectively connected with a U.S. trade or business, information reporting may
apply to such payments. Payment of the proceeds from a sale of a Note to or
through the U.S. office of a broker will be subject to information reporting
and backup withholding unless the holder or beneficial owner certifies as to
its taxpayer identification number or otherwise establishes an exemption from
information reporting and backup withholding.
 
  Under the Final Regulations (described above under "Certain Federal Income
Tax Consequences--U.S. Federal Income Taxation of Non-U.S. Holders"),
generally effective for payments after December 31, 1998, information
reporting and backup withholding will not be required if the Non-U.S. Holder
has (i) furnished documentation establishing eligibility for the Portfolio
Interest Exemption or a Treaty Exemption (provided that, in the case of a sale
of a Note by an individual, Form W-8 (or any substitute) includes a
certification that the individual has not been, and does not intend to be,
present in the United States for 183 days or more days for the
 
                                      94
<PAGE>
 
relevant period) or (ii) otherwise establishes an exemption. Certain
additional rules may apply where the Notes are held through a custodian,
nominee, broker, foreign partnership or foreign intermediary.
 
  EACH NON-U.S. HOLDER SHOULD CONSULT THE HOLDER'S TAX ADVISOR AS TO THE
APPLICATION OF THE FINAL REGULATIONS AND THE PROCEDURES THEREUNDER FOR
ESTABLISHING FOREIGN STATUS FOR PURPOSES OF INFORMATION REPORTING AND BACKUP
WITHHOLDING.

                             PLAN OF DISTRIBUTION
 
  Each Participating Broker-Dealer that receives Exchange 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 Exchange Notes. This
Prospectus, as it may be amended or supplemented from time to time, may be
used by a Participating Broker-Dealer in connection with resales of Exchange
Notes received in exchange for Old Notes where such Old Notes were acquired 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, as amended or supplemented, available to any
Participating Broker-Dealer for use in connection with any such resale
(provided that the Company receive notice from such Participating Broker-
Dealer within 30 days after the consummation of the Exchange Offer of his
status as a Participating Broker-Dealer).
 
  The Company will not receive any proceeds from any sales of the Exchange
Notes by Participating Broker Dealers. Exchange Notes received by
Participating 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 Exchange 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 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 Participating Broker-
Dealer and/or the purchasers of any such Exchange Notes. Any Participating
Broker-Dealer that resells the Exchange 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 Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of Exchange 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 Participating 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 (subject to receiving
notice as set forth above), the Company will promptly send additional copies
of this Prospectus and any amendment or supplement to this Prospectus to any
Participating Broker-Dealer that requests such documents in the Letter of
Transmittal.
 
  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 Exchange Notes by holders who are entitled to participate in
this 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 Exchange
Notes will constitute a new issue of securities with no established trading
market. The Company does not intend to list the Exchange Notes on any national
securities exchange or to seek the admission thereof to trading in the
National Association of Securities Dealers Automated Quotation System. In
addition, such market making activity will be subject to the limits imposed by
the Securities Act and the Exchange Act and may be limited during the Exchange
Offer and the pendency of the Shelf Registration Statements. Accordingly, no
assurance can be given that an active public or other market will develop for
the Exchange Notes or as to the liquidity of the trading market for the
Exchange Notes. If a trading market does not develop or is not maintained,
holders of the Exchange Notes may experience difficulty in reselling the
Exchange Notes or may be unable to sell them at all. If a market for the
Exchange Notes develops, any such market may be discontinued at any time.
 
                                 LEGAL MATTERS
 
  Certain legal matters with regard to the validity of the Exchange Notes will
be passed upon for the Company by Kirkland & Ellis (a partnership including
professional corporations), Chicago, Illinois.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The Registrant is incorporated under the laws of the State of Delaware.
Section 145 of the General Corporation Law of the State of Delaware provides
that a Delaware corporation may indemnify any persons who are, or are
threatened to be made, parties to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of such corporation), by reason of
the fact that such person is or was an officer, director, employee or agent of
such corporation, or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation or enterprise. The
indemnity may include expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with such action, suit or proceedings, provided such person
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the corporation's best interests and, with respect to any criminal
action or proceedings, had no reasonable cause to believe that his conduct was
illegal. A Delaware corporation may also indemnify any persons who are, or are
threatened to be made, a party to any threatened, pending or completed action
or suit by or in the right of the corporation by reason of the fact that such
person was a director, officer, employee or agent of such corporation, or is
or was serving at the request of such corporation as a director, officer,
employee or agent of another corporation or enterprise. The indemnity may
include expenses (including attorneys' fees) actually and reasonably incurred
by such person in connection with the defense or settlement of such action or
suit, provided such person acted in good faith and in a manner he reasonably
believed to be in or not opposed to the corporation's best interests except
that no indemnification is permitted without judicial approval if the officer
or director is adjudged to be liable to the corporation. To the extent that an
officer or director is successful on the merits or otherwise in the defense of
any action referred to above, the corporation must indemnify him against the
expenses which such officer or director has actually and reasonably incurred
in connection with such defense.
 
  Under Article Ninth of the Registrant's Restated Certificate of
Incorporation and Article XII of its By-Laws, as amended, the Registrant shall
indemnify any person who was or is made a party or is threatened to be made
party to or is otherwise involved in any action, suit or proceedings, whether
civil, criminal, administrative or investigative, by reason of the fact that
he or she is or was a director or officer of the Registrant (including any
predecessor corporation of the Registrant), or is or was serving at the
request of the Registrant as a director, officer, employee or agent of another
corporation or of a partnership, joint venture, trust or other enterprise,
including service with respect to employee benefit plans, against all
expenses, liability and loss (including attorneys' fees, judgments, fines,
ERISA excise taxes or penalties and amounts paid in settlement) reasonably
incurred or suffered by such person in connection therewith to the fullest
extent authorized by the General Corporation Law of the State of Delaware.
Such right of indemnification shall be a contract right and shall not be
exclusive of any other right which such directors, officers or representatives
may have or hereafter acquire under any statute, the Registrant's Restated
Certificate of Incorporation, the Registrant's By-Laws, agreement, vote of
stockholders or disinterested directors or otherwise.
 
  In addition, Section 102 of the General Corporation Law of the State of
Delaware allows a corporation to eliminate the personal liability of a
director of a corporation to the corporation or to any of its stockholders for
monetary damages for a breach of fiduciary duty as a director, except in the
case where the director (i) breaches his duty of loyalty, (ii) fails to act in
good faith, engages in intentional misconduct or knowingly violates a law,
(iii) authorized the payment of a dividend or approves a stock repurchase in
violation of the General Corporation Law of the State of Delaware or (iv)
obtains an improper personal benefit. Article Eighth of the Registrant's
Restated Certificate of Incorporation includes a provision which eliminates
directors' personal liability to the full extent permitted under the General
Corporation Law of the State of Delaware.
 
  The Registrant maintains a policy of directors and officers liability
insurance covering certain liabilities incurred by its directors and officers
in connection with the performance of their duties.

ITEM 22. UNDERTAKINGS.
 
  (a) The undersigned Registrant hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this registration statement:
 
      (i) To include any prospectus required by Section10(a)(3) of the
    Securities Act of 1933;
 
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the registration statement;
 
                                     II-2
<PAGE>
 
      (iii) To include any material information with respect ot the plan of
    distribution not previously disclosed in the registration statement or
    any material change to such information in the registration statement;
 
    provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
  information required to be included in a post-effective amendment by those
  paragraphs is contained in periodic reports filed with or furnished to the
  Commission by the registrant pursuant to Section 13 or Section 15(d) of the
  Securities Exchange Act of 1934 that are incorporated by reference in the
  registration statement.
 
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be the
  initial bona fide offering thereof.
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.
 
  (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be the initial bona fide offering
thereof.
 
  (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to 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 Securities
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
Securities Act and will be governed by the final adjudication of such issue.
 
  (d) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.
 
  (e) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

such specified Person or (b) such acquisition by the specified Person.

          "Additional Interest" shall have the meaning set forth in the

                                THE SECURITIES

          SECTION 2.1  Form and Dating.

          (a)  Global Securities.  Securities offered and sold to QIBs in
reliance on Rule 144A shall be issued initially substantially in the form of
Exhibit A hereto in the name of Cede & Co. as nominee of DTC, duly executed by
the Company and authenticated by the Trustee as hereinafter provided.  Any such
Security shall be referred to herein as the "144A Global Security."  Securities
offered and sold in reliance on Regulation S shall be issued initially
substantially in the form of Exhibit A hereto in the name of Cede & Co. as
nominee of DTC, duly executed by the Company and authenticated by the Trustee as
hereinafter provided.  Any such Security shall be referred to herein as the
"Regulation S Global Security."  Unrestricted Global Securities shall be issued
initially in accordance with Sections 2.6(b)(iv), 2.6(c)(ii) and 2.6(e) in the
name of Cede & Co. as nominee of DTC, duly executed by the Company and
authenticated by the Trustee as hereinafter provided.  The aggregate principal
amount of each of the Global Security may from time to time be increased or
decreased by adjustments made on the records of the Trustee as hereinafter
provided.

          Each Global Security shall represent such of the outstanding
Securities as shall be specified therein and each shall provide that it shall
represent the aggregate principal amount of outstanding Securities from time to
time endorsed thereon and that the aggregate principal amount of outstanding
Securities represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges, redemptions and transfers of interests
therein in accordance with the terms of this Indenture.  Any change in the
aggregate principal amount of a Global Security to reflect the amount of any
increase or decrease in the principal amount of outstanding Securities
represented thereby shall be made by the Trustee in accordance with reasonable
instructions given by the Holder thereof as required by Section 2.6 hereof and
shall be conclusively reflected on the books and records of the Trustee.

          Upon the issuance of the Global Security to DTC, DTC shall credit, on
its internal book-entry registration and transfer system, its Participant's
accounts with the respective interests owned by such Participants.  Interests in
the Global Securities shall be limited to Participants, including Euroclear and
Cedel, and indirect Participants.

          The Participants shall not have any rights either under this
Indenture or under any Global Security with respect to such Global Security held
on their behalf by DTC, 
<PAGE>
 
                                      -29-

and DTC may be treated by the Company, the Trustee and any agent of the Company
or the Trustee as the absolute owner of such Global Securities for the purpose
of receiving payment of or on account of the principal of and, subject to the
provisions of this Indenture, interest and Additional Interest, if any, on the
Global Securities and for all other purposes. Notwithstanding the foregoing,
nothing herein shall prevent the Company, the Trustee or any agent of the
Company or the Trustee from giving effect to any written certification, proxy or
other authorization furnished by DTC or impair, as between DTC and its
Participants, the operation of customary practices of DTC governing the exercise
of the rights of an owner of a beneficial interest in any Global Security.

          The provisions of the "Operating Procedures of the Euroclear System"
and "Terms and Conditions Governing Use of Euroclear" and the "General Terms and
Conditions of Cedel Bank" and "Customer Handbook" of Cedel, as in effect from
time to time, shall be applicable to interests in the Regulation S Global
Security that are held by the Participants through Euroclear or Cedel.

          (b)  Physical Securities.  Securities issued substantially in the form
of Exhibit A hereto, in certificated form and in the names of the purchasers
thereof (or their nominees), duly executed by the Company and authenticated by
the Trustee as hereinafter provided shall be referred to herein as the "Physical
Securities."  Except as provided in Section 2.6(a) owners of beneficial
interests in the Global Securities will not be entitled to receive Physical
Securities.

          (c)  Securities.  The provisions of the form of Securities contained
in Exhibit A hereto are incorporated herein by reference.  The Securities and
the Trustee's Certificates of Authentication shall be substantially in the form
of Exhibit A hereto.  The Securities may have notations, legends or endorsements
required by law, stock exchange rule or usage and provided to the Trustee in
writing by the Company.  The Company shall approve the form of the Securities
and any notation, legend or endorsement on them.  If required, the Securities
may bear the appropriate legend regarding original issue discount for federal
income tax purposes.  Each Security shall be dated the date of its
authentication.  The terms and provisions contained in the Securities shall
constitute, and are hereby expressly made, a part of this Indenture.

          SECTION 2.2  Execution and Authentication.

          Two Officers of the Company shall sign the Securities for the Company
by manual or facsimile signature.

          If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless.
<PAGE>
 
                                      -30-

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

          The Trustee shall authenticate (i) Initial Notes for issue on the
Issue Date in the aggregate principal amount of $100,000,000, (ii) Private
Exchange Securities from time to time only in exchange for a like principal
amount of Initial Securities and (iii) Unrestricted Securities from time to time
only in exchange for a like principal amount of Initial Securities, in each case
upon a written order signed by an Officer of the Company.  The order shall be
based upon a Board Resolution of the Company and shall specify the amount of
Securities to be authenticated and the date on which the original issue of
Securities is to be authenticated.  The order shall also provide instructions
concerning registration, legends, if any, pursuant to Section 2.6(f), amounts
for each Holder and delivery.  The aggregate principal amount of Securities
outstanding at any time may not exceed $100,000,000 except as provided in
Section 2.7.  The Securities shall be issued only in registered form, without
coupons and only in denominations of $1,000 and any integral multiple thereof.

          SECTION 2.3  Registrar and Paying Agent.

          The Company shall maintain an office or agency where Securities may be
presented for registration of transfer or for exchange ("Registrar") and an
office or agency where Securities may be presented for payment ("Paying Agent").
The Company may have one or more additional paying agents.  The term "Paying
Agent" includes any additional paying agent.

          The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture.  The agreement shall implement the
provisions of this Indenture that relate to such Agent and shall, if required,
incorporate the provisions of the TIA.  The Company shall notify the Trustee in
writing of the name and address of any such Agent.  If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation in accordance with the provisions of
Section 7.7.

          The Company initially appoints the Trustee as Registrar and Paying
Agent.  The Company shall give written notice to the Trustee in the event that
the Company decides to act as Registrar.

          The Company shall require each Paying Agent to agree in writing to
hold in trust for the benefit of Securityholders or the Trustee all money held
by the Paying Agent for the payment of principal of or interest on the
Securities (whether such money has been paid to it by the Company or any other
obligor on the Securities), and the Company and the Paying Agent shall each
notify the Trustee of any default by the Company (or any other obligor on the
Securities) in making any such payment.  The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee and account for any
funds 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 pay all money held by it to the Trustee and to account for any funds
disbursed.  Upon making such payment the Paying Agent shall have no further
liability for the money delivered to the Trustee.

          SECTION 2.5  Securityholder 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
Securityholders.  If the Trustee is not the Registrar, the Company shall furnish
to the Trustee at least five Business Days before each Interest Payment Date and
at such other times as the Trustee may request in writing a list in such form
and as of such date as the Trustee may reasonably require of the names and
addresses of Securityholders.

          SECTION 2.6  Transfer and Exchange.

          (a)  Transfer and Exchange of Global Securities.  Transfer of the
Global Securities shall be by delivery.  Global Securities may not be
transferred as or exchanged for Physical Securities except (i) if DTC notifies
the Company that it is unwilling or unable to continue to act as depositary with
respect to the Global Securities or ceases to be a clearing agency registered
under the Exchange Act and, in either case, a successor depositary registered as
a clearing agency under the Exchange Act is not appointed by the Company within
120 days, (ii) at any time if the Company in its sole discretion determines that
the Global Securities (in whole but not in part) should be exchanged for
Physical Securities or (iii) if the owner of an interest in the Global
Securities requests such Physical Securities, following an Event of Default
under this Indenture, in a writing delivered through DTC to the Trustee.

          Upon the occurrence of any of the events specified in the previous
paragraph, Physical Securities shall be issued in such names as DTC shall
instruct the Trustee and the Trustee shall cause the aggregate principal amount
of the applicable Global Security to be reduced accordingly and direct DTC to
make a corresponding reduction in its book-

entry system. The Company shall execute and the Trustee shall authenticate and
deliver to the Person designated in such instructions a Physical Security in the
appropriate principal amount. The Trustee shall deliver such Physical Securities
to the Persons in whose names such Securities are so registered. Physical
Securities issued in exchange for an Initial Global Security pursuant to this
Section 2.6 (a) shall bear the Securities Act Legend and shall be subject to all
restrictions on transfer contained therein. Global Securities may also be
exchanged or replaced, in whole or in part, as provided in Sections 2.7 and 2.8.
Every Security authenticated and delivered in exchange for, or in lieu of, a
Global Security or any portion thereof, pursuant to Section 2.7 or 2.8, shall be
authenticated and delivered in the form of, and shall be, a Global Security. A
Global Security may not be exchanged for another Security other than as provided
in this Section 2.6(a).

          (b)  Transfer and Exchange of Interests in Global Securities.  The
transfer and exchange of interests in Global Securities shall be effected
through DTC, in accordance with this Indenture and the procedures of DTC
therefor.  Interests in Initial Global Securities shall be subject to
restrictions on transfer comparable to those set forth herein to the extent
required by the Securities Act.  The Trustee shall have no obligation to
ascertain DTC's compliance with any such restrictions on transfer.  Transfers of
interests in Global Securities shall also require compliance with subparagraph
(i) below, as well as one or more of the other following subparagraphs as
applicable:

          (i)    All Transfers and Exchanges of Interests in Global Securities.
     In connection with all transfers and exchanges of interests in Global
     Securities (other than transfers of interests in a Global Security to
     Persons who take delivery thereof in the form of an interest in the same
     Global Security), the transferor of such interest must deliver to the
     Registrar (1) instructions given in accordance with the Applicable
     Procedures from a Participant or an indirect Participant directing DTC to
     credit or cause to be credited an interest in the specified Global Security
     in an amount equal to the interest to be transferred or exchanged, (2) a
     written order given in accordance with the Applicable Procedures containing
     information regarding the Participant account to be credited with such
     increase and (3) instructions given by the Holder of the Global Security to
     effect the transfer referred to in (1) and (2) above.

          (ii)   Transfer of Interests in the Same Initial Global Security.
     Interests in any Initial Global Security may be transferred to Persons who
     take delivery thereof in the form of an interest in the same Initial Global
     Security in accordance with the transfer restrictions set forth in Section
     2.6(f) hereof.  It shall be the sole responsibility of the selling
     beneficial owner to deliver these transfer documents, if any are required,
     to the Company and the Trustee shall have no responsibility or duty to
     collect the transfer documentation set forth in Section 2.6(f).

          (iii)  Transfer of Interests to Another Initial Global Security.
     Interests in any Initial Global Security may be transferred to Persons who
     take delivery thereof in the form of an interest in another Initial Global
     Security if the Registrar receives the following:

                 (A) if the transferee will take delivery in the form of an
          interest in the 144A Global Security, then the transferor must deliver
          a certificate in the form of Exhibit D hereto, including the
          certifications in item 1 thereof; or

                 (B) if the transferee will take delivery in the form of an

          deliver a certificate in the form of Exhibit D hereto, including the
          certifications in item 2 thereof.

          (iv)   Transfer and Exchange of Interests in Initial Global Security
     for Interests in an Unrestricted Global Security. Interests in any Initial
     Global Security may be exchanged by the holder thereof for an interest in
     the Unrestricted Global Security or transferred to a Person who takes
     delivery thereof in the form of an interest in the Unrestricted Global
     Security if:

                 (A) such exchange or transfer is effected pursuant to the
          Exchange Registration Statement in accordance with the Registration
          Rights Agreement and the Company delivers an Officers' Certificate to
          the Trustee stating that such Exchange Registration Statement has
          become effective and directing the Trustee to effect the exchange or
          transfer on the terms set forth therein;

                 (B) any such transfer is effected pursuant to the Shelf

          Agreement and the Company delivers an Officers' Certificate to the
          Trustee stating that such Shelf Registration Statement has become
          effective and directing the Trustee to effect the exchange or transfer
          on the terms set forth therein; or

                 (C) the Registrar receives the following:

                     (1) if the holder of such an interest in an Initial Global
               Security proposes to exchange it for an interest in the
               Unrestricted Global Security, a certificate from such Holder in
               the form of Exhibit E hereto, including the certifications in
               item 1(a) thereof;

                     (2) if the holder of such an interest in an Initial Global
               Security proposes to transfer it to a Person who shall take
               delivery
<PAGE>
 
                                      -34-

               thereof in the form of an interest in an Unrestricted Global
               Security, a certificate in the form of Exhibit D hereto,
               including the certification in item 4 thereof; and

               on transfer contained herein and in Section 2.6(f) hereof are not
               required in order to maintain compliance with the Securities Act.

     when an Unrestricted Global Security has not yet been issued, the Company
     shall issue and, upon receipt of an authentication order in accordance with
     Section 2.2, the Trustee shall authenticate one or more Unrestricted Global
     Securities in an aggregate principal amount equal to the principal amount
     of interests in the Initial Global Securities transferred pursuant to
     paragraph (B) above, provided the Company has made appropriate arrangements
     with DTC prior to delivery of such an authentication order to the Trustee.

             (v)    Notation by the Trustee of Transfer of Interests Among
     Global Securities. Upon satisfaction of the requirements for transfer of
     interests in Global Securities pursuant to clauses (iii) or (iv) above, the
     Trustee shall reduce or cause to be reduced the aggregate principal amount
     of the relevant Global Security from which the interests are being
     transferred, and increase or cause to be increased the aggregate principal
     amount of the Global Security to which the interests are being transferred,
     in each case, by the principal amount so transferred and shall direct DTC
     to make corresponding adjustments in its book-entry system. No transfer of
     interests of a Global Security shall be effected until, and any transferee
     pursuant thereto shall succeed to the rights of a holder of such interests
     only when, the Registrar has made appropriate adjustments to the applicable
     Global Security in accordance with this paragraph.

          (c)  Transfer or Exchange of Physical Securities for Interests in a
Global Security.

               (i)  If any Holder of Physical Securities required to contain
     the Securities Act Legend proposes to exchange such Securities for an
     interest in a Global Security or to transfer such Physical Securities to a
     Person who takes delivery thereof in the form of an interest in a Global
     Security, then, upon receipt by the Registrar of the following
     documentation (all of which may initially be submitted by facsimile,

     originals):

                    (A) if the Holder of such Physical Registered Securities
          proposes to exchange such Securities for an interest in an Initial
          Global Security, a certificate from such Holder in the form of Exhibit
          E hereto, including the certifications in item 2 thereof;

                    (C) if such Physical Securities are being transferred to a
          Non-U.S. Person (as defined in Regulation S) in an offshore
          transaction in accordance with Rule 904 under the Securities Act, a
          certificate to the effect set forth in Exhibit D hereto, including the

     above, the 144A Global Security, in the case of clause (C) above, the
     Regulation S Global Security, and direct DTC to make a corresponding
     increase in its book-entry system.

             (ii)   A Holder of Physical Securities required to contain the
     Securities Act Legend may exchange such Securities for an interest in the
     Unrestricted Global Security or transfer such Restricted Physical
     Securities to a Person who takes delivery thereof in the form of an
     interest in the Unrestricted Global Security only:

                    (A) if such exchange or transfer is effected pursuant to the
          Exchange Registration Statement in accordance with the Registration
          Rights Agreement and the Company delivers an Officers' Certificate to
          the Trustee stating that such Exchange Registration Statement has
          become effective and directing the Trustee to effect the exchange or
          transfer on the terms set forth therein;

                                      -36-

               (C) upon receipt by the Registrar of the following documentation
          (all of which may be submitted by facsimile):

                       (1) if the Holder of such Physical Securities proposes to
               exchange such Securities for an interest in the Unrestricted
               Global Security, a certificate from such Holder in the form of
               Exhibit E hereto, including the certifications in item 1(b)
               thereof;

                       (2) the Holder of such Registered Securities proposes to
               transfer such Securities to a Person who shall take delivery
               thereof in the form of an interest in the Unrestricted Global
               Security, a certificate in the form of Exhibit D hereto,
               including the certifications in item 4 thereof; and

                       (3) in each such case set forth in this paragraph (C), an
               Opinion of Counsel in form reasonably acceptable to the Company,
               to the effect that such exchange or transfer is in compliance
               with the Securities Act and that the restrictions on transfer
               contained herein and in Section 2.6(f) hereof are not required in
               order to maintain compliance with the Securities Act.

     If any such transfer is effected pursuant to paragraph (B) above at a time
     when an Unrestricted Global Security has not yet been issued, the Company
     shall issue and, upon receipt of an authentication order in accordance with
     Section 2.2, the Trustee shall authenticate (i) one or more Unrestricted
     Global Securities in an aggregate principal amount equal to the principal
     amount of Physical Securities transferred pursuant to paragraph (B) above.

          (d)  Transfer and Exchange of Physical Securities.

               (i)    Transfer of a Physical Security to Another Physical
     Security. Following the occurrence of one or more of the events specified
     in Section 2.6(a), a Physical Security may be transferred to Persons who
     take delivery thereof in the form of another Physical Security if the
     Registrar receives the following:

                      (A) if the transfer is being effected pursuant to and in
          accordance with Rule 144A, then the transferor must deliver a
          certificate in the form of Exhibit D hereto, including the
          certifications in item 3(a) thereof; or
<PAGE>
 
                                      -37-

               (B) if the transfer is being effected pursuant to and in
          accordance with Regulation S, then the transferor must deliver a
          certificate in the form of Exhibit D hereto, including the
          certifications in item 3(b) thereof.

          (ii)   Transfer and Exchange of Restricted Physical Security for
     Physical Security Which Does Not Bear the Securities Act Legend.  Following
     the occurrence of one or more of the events specified in Section 2.6(a) and
     the receipt by the Trustee of an Officers' Certificate stating that such
     events have occurred, a Restricted Physical Security may be exchanged by
     the Holder thereof for a Physical Security or transferred to a Person who
     takes delivery thereof in the form of a Physical Security which does not
     bear the Securities Act Legend if:

                 (A) such exchange or transfer is effected pursuant to the
          Exchange Registration Statement in accordance with the Registration
          Rights Agreement and the receipt by the Trustee of an Officers'
          Certificate stating that such events have occurred;

                 (B) any such transfer is effected pursuant to the Shelf
          Registration Statement in accordance with the Registration Rights
          Agreement and the receipt by the Trustee of an Officers' Certificate
          stating that such events have occurred; or

                 (C)  the Registrar receives a certificate from such Holder in
          the form of Exhibit E hereto, including the certifications in item
          1(c) thereof and an Opinion of Counsel in form reasonably acceptable
          to the Company, to the effect that such exchange or transfer is in
          compliance with the Securities Act and, that the restrictions on
          transfer contained herein and in Section 2.6(f) hereof are not
          required in order to maintain compliance with the Securities Act.

          (iii)  Exchange of Physical Securities.  When Physical Securities are
     presented by a Holder to the Registrar with a request to register the
     exchange of such Physical Securities for an equal principal amount of
     Physical Securities of other authorized denominations, the Registrar shall
     make the exchange as requested only if the Physical Securities are endorsed
     or accompanied by a written instrument of transfer in form satisfactory to
     the Registrar duly executed by such Holder or by his attorney duly
     authorized in writing and shall be issued only in the name of such Holder
     or its nominee and the transfer documentation required in Section
     2.6(d)(ii). The Physical Securities issued in exchange for Physical
     Securities shall bear the Securities Act Legend and shall be subject to all
     restrictions on transfer contained herein in each case to the same extent
     as the Physical Securities so exchanged.
<PAGE>
 
                                      -38-

          (iv)   Return of Physical Securities.  In the event of a transfer
     pursuant to clauses (i) or (ii) above and the Holder thereof as delivered
     certificates representing an aggregate principal amount of Securities in
     excess of that to be transferred, the Company shall execute and the Trustee
     shall authenticate and deliver to the Holder of such Security without
     service charge, a new Physical Security or Securities of any authorized
     denomination requested by the Holder, in an aggregate principal amount
     equal to the portion of the Security not so transferred.

          (e)  Exchange Offer.  Upon the occurrence of the Exchange Offer (as
defined in the Registration Rights Agreement) in accordance with the
Registration Rights Agreement, the Company shall issue and, upon receipt of an
Officers' Certificate stating that the Exchange Registration Statement has
become effective and that the Exchange Offer has occurred and an authentication
order in accordance with Section 2.2, the Trustee shall authenticate one or more
Unrestricted Global Securities in an aggregate principal amount equal to the
principal amount of the interests in the Initial Global Securities and
Restricted Physical Securities tendered for acceptance by persons participating
therein.  Concurrently with the issuance of such Securities, the Trustee shall
cause the aggregate principal amount of the applicable Initial Global Securities
to be reduced accordingly and direct DTC to make a corresponding reduction in
its book-entry system.  The Trustee shall cancel any Restricted Physical
Certificates in accordance with Section 2.9 hereof.

          In the case that one or more of the events specified in Section 2.6(a)
have occurred, upon the occurrence of such Exchange Offer, the Company shall
issue and, upon receipt of an authentication order in accordance with Section
2.2, the Trustee shall authenticate Unrestricted Physical Securities in an
aggregate principal amount equal to the principal amount of the Restricted
Physical Securities tendered for acceptance by persons participating therein.

          (f)  Legends.

          Each Initial Global Security and each Restricted Physical Security
shall bear the legend (the "Securities Act Legend") in substantially the
following form:

          "THIS NOTE (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A
     TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES

     FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED
     BY RULE 144A THEREUNDER."

          "THE HOLDER OF THIS NOTE AGREES FOR THE BENEFIT OF THE
     COMPANY THAT (A) THIS NOTE MAY BE OFFERED, RESOLD, PLEDGED OR
     OTHERWISE TRANSFERRED ONLY (I) INSIDE THE UNITED STATES TO A
     PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED
     INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES
     ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (II)

     NOTIFY ANY PURCHASER OF THIS NOTE FROM IT OF THE RESALE
     RESTRICTIONS REFERRED TO IN (A) ABOVE."

          (g)  Global Security Legend.  Each Global Security shall bear a legend
in substantially the following form:

          "UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR
     SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE
     TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITORY TRUST COMPANY, A
     NEW YORK CORPORATION ("DTC"), TO A NOMINEE OF DTC, OR BY ANY SUCH
     NOMINEE OF DTC, OR BY DTC TO A SUCCESSOR DEPOSITARY OR A NOMINEE
     OF SUCH SUCCESSOR DEPOSITARY. UNLESS THIS CERTIFICATE IS
     PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF DTC TO THE COMPANY
     OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT,
     AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE &
     CO. OR SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED
     REPRESENTATIVE OF DTC (AND ANY PAYMENT HEREON IS MADE TO CEDE &

     HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

          TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO
     TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF CEDE & CO. OR
     TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS
     OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS
     MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN SECTION 2.6
     OF THE INDENTURE."

          (h)  Cancellation and/or Adjustment of Global Securities.  At such
time as all interests in the Global Securities have been exchanged for Physical
Securities, all Global Securities shall be returned to or retained and canceled
by the Trustee in accordance with Section 2.9 hereof.  At any time prior to such
cancellation, if any interest in a Global Security is exchanged for an interest
in another Global Security or for Physical Securities, the principal amount of
Securities represented by such Global Security shall be reduced accordingly and
all such changes to such Global Security shall be reflected on the books and
records of the Trustee, by the Trustee to reflect such reduction.

          (i)    General Provisions Relating to All Transfers and Exchanges.

                 (i)    To permit registrations of transfers and exchanges, the
     Company shall execute and the Trustee shall authenticate Global Securities
     and Physical Securities upon a written order signed by an Officer of the
     Company or at the Registrar's request.

                 (ii)   No service charge shall be made to a Holder for any
     registration of transfer or exchange, but the Company may require payment
     of a sum sufficient to cover any stamp or transfer tax or similar
     governmental charge payable in connection therewith (other than any such
     stamp or transfer taxes or similar governmental charge payable upon
     exchange or transfer pursuant to Sections 2.8 and 4.11 hereof).

                 (iii)  All Global Securities and Physical Securities issued
     upon any registration of transfer or exchange of Global Securities or
     Physical Securities shall be the valid obligations of the Company,
     evidencing the same debt, and entitled to the same benefits under this
     Indenture, as the Global Securities or Physical Securities surrendered upon
     such registration of transfer or exchange.
<PAGE>
 
                                      -41-

                 (iv)   The Company shall not be required (A) to issue, to
     register the transfer of or to exchange Securities during a period
     beginning at the opening of business 15 days before the day of any
     selection of Securities for redemption and ending at the close of business
     on the day of selection, (B) to register the transfer of or to exchange any
     Security so selected for redemption in whole or in part, except the
     unredeemed portion of any Security being redeemed in part or (C) to
     register the transfer of or to exchange a Security between a record date
     and the next succeeding Interest Payment Date.

                 (v)    Prior to due presentment for the registration of a
     transfer of any Security, the Trustee, any Agent and the Company may deem
     and treat the Person in whose name any Security is registered as the
     absolute owner of such Security for the purpose of receiving payment of
     principal of and interest on such Securities and for all other purposes,
     and none of the Trustee, any Agent or the Company shall be affected by
     notice to the contrary.

          Notwithstanding anything herein to the contrary, as to any
certification or certificate delivered to the Registrar pursuant to this Section
2.6, the Registrar's duties shall be limited to confirming that any such
certification or certificate delivered to it is in the form of Exhibit D or E
attached hereto.  The Registrar shall not be responsible for confirming the
truth or accuracy of any representations made in any such certification or
certificate.

          SECTION 2.7  Replacement Securities.

          If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

          If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be reasonably required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company or the Trustee that such Security has been acquired by
a bona fide purchaser, the Company shall execute and upon its request the
Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or
stolen Security, a new Security of like tenor and principal amount, having
endorsed thereon and bearing a number not contemporaneously outstanding.

          Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that 
<PAGE>
 
                                     -42-

may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee) connected therewith.

          Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

          SECTION 2.8  Temporary Securities.

          Pending the preparation of definitive Securities, the Company may
execute and, upon Company Order, the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued, and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

          If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 10.2, without charge to
the Holder.  Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities of
authorized denominations and like tenor.  Until so exchanged the temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities.

          SECTION 2.9  Cancellation.

          All Securities surrendered for payment, redemption or registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly canceled by it.  The Company
may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Securities so delivered shall be
promptly canceled by the Trustee. No Securities shall be authenticated in 
<PAGE>
 
                                     -43-

lieu of or in exchange for any Securities canceled as provided in this Section,
except as expressly permitted by this Indenture. All canceled Securities held by
the Trustee shall be destroyed by the Trustee and upon the Company's written
request, the Trustee shall deliver a certificate of destruction to the Company.

          SECTION 2.10  Defaulted Interest.

          Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

             (1) The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Securities (or their respective
     Predecessor Securities) are registered at the close of business on a date
     for the payment of such Defaulted Interest (herein called a "Special Record
     Date"), which shall be fixed in the following manner.  The Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each Security and the date of the proposed payment, and at
     the same time the Company shall deposit with the Trustee an amount of money
     equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this clause provided. Thereupon the Company
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which shall be not more than 15 days prior to the date of the proposed
     payment. The Company shall promptly notify the Trustee of such Special
     Record Date and, in the name and at the expense of the Company, the Trustee
     shall cause notice of the proposed payment of such Defaulted Interest and
     the Special Record Date therefor to be mailed, first-class postage prepaid,
     to each Holder at his address as it appears in the Security Register, not
     less than five Business Days prior to such Special Record Date. Notice of
     the proposed payment of such Defaulted Interest and the Special Record Date
     therefor having been so mailed, such Defaulted Interest shall be paid not
     later than the fifteenth day after such Special Record Date to the Persons
     in whose names the Securities (or their respective Predecessor Securities)
     are registered at the close of business on such Special Record Date.

             (2) The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Securities may be listed, and upon such
     notice as may be re-
<PAGE>
 
                                     -44-

     quired by such exchange, if, after notice given by the Company to the
     Trustee of the proposed payment pursuant to this clause, such manner of
     payments shall be deemed practicable by the Trustee.

          SECTION 2.11  CUSIP or CINS Number.

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

          SECTION 2.12  Payments of Interest.

          (a)  The Holder of a Physical Security at the close of business on the
Regular Record Date with respect to any Interest Payment Date shall be entitled
to receive the interest and Additional Interest, if any, payable on such
Interest Payment Date notwithstanding any transfer or exchange of such Physical
Security subsequent to the regular record date and prior to such Interest
Payment Date, except if and to the extent the Company shall default in the
payment of the interest or Additional Interest due on such Interest Payment
Date, in which case such Defaulted Interest and Additional Interest, if any,
shall be paid in accordance with Section 2.10; provided that, in the event of an

          SECTION 4.1  Payment of Securities.

          The Company shall pay the principal of and interest on the Securities
on the dates and in the manner provided in the Securities and this Indenture.

          An installment of principal or interest shall be considered paid on
the date due if the Trustee or Paying Agent (other than the Company or any
Subsidiary of the Company or any Affiliate of any thereof) holds on such date by
12:00 noon, New York City time, immediately available funds designated for and
sufficient to pay such installment.

          The Company shall pay interest on overdue principal and on overdue
installments of interest, in each case at the rate per annum specified in the
Securities, to the extent lawful.

          SECTION 4.2  Maintenance of Office or Agency.

          The Company shall maintain in the Borough of Manhattan, the City of
New York, an office or agency, where Securities may be surrendered for
registration of transfer or exchange or for presentation for payment and where
notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or
agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
address of the Trustee set forth in Section 10.2.
<PAGE>
 
                                     -46-

          The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations,
provided that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York, for such purposes.  The Company will give
prompt written notice to the Trustee of any such designation or rescission and
of any change in the location of any such other office or agency.

          The Company hereby initially designates the offices of the Trustee as
set forth in Section 10.2 as an agency of the Company in accordance with Section
2.3.

          SECTION 4.3  Corporate Existence.

          Subject to Article V hereof, the Company shall do or cause to be done,
at its own cost and expense, all things necessary to and will cause each of its
Subsidiaries to, preserve and keep in full force and effect the corporate
existence and rights (charter and statutory), licenses and/or franchises of the
Company and each of its Subsidiaries, provided that the Company shall not be
required to preserve any such right, license or franchise, or the corporate
existence of any of its Subsidiaries, if in the reasonable and good faith
judgment of the Board of Directors of the Company (i) such preservation or
existence is not desirable in the conduct of business of the Company or such
Subsidiary and (ii) the loss of such right, license or franchise or the
dissolution of such Subsidiary is not adverse in any material respect to the
Holders or to the Company or the ability of the Company to satisfy its
obligations hereunder.

          SECTION 4.4  Payment of Taxes and Other Claims.

          The Company shall and shall cause each of its Subsidiaries to pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all material taxes, assessments and governmental charges levied
or imposed upon its or its Subsidiaries' income, profits or property and (b) all
material lawful claims for labor, materials and supplies which, if unpaid, might
by law become a Lien upon its property or the property of any of its
Subsidiaries, provided 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 or validity is being contested in good faith
by appropriate negotiations or proceedings promptly instituted and diligently
conducted and for which disputed amounts adequate reserves (in the reasonable
and good faith judgment of the Board of Directors of the Company) have been
made.

          SECTION 4.5  Maintenance of Properties; Insurance; Books and Records;

          (a)  The Company shall, and shall cause each of its Subsidiaries to,
at all times cause all properties used or useful in the conduct of its business
to be maintained and kept in good condition, repair and working order
(reasonable wear and tear excepted) and supplied with all necessary equipment,
and shall cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereto, provided that nothing in this Section 4.5
shall prevent the Company or any Subsidiary from discontinuing the operation or
maintenance of any of such properties, or disposing of any of them, if such
discontinuance or disposal is (i) in the ordinary course of business, (ii) in
the reasonable and good faith judgment of the Board of Directors of the Company
or the Subsidiary concerned, as the case may be, desirable in the conduct of the
business of the Company or such Subsidiary, as the case may be, or (iii)
otherwise permitted by this Indenture.

          (b)  The Company shall, and shall cause each of its Subsidiaries to
maintain with financially sound and reputable insurers such insurance (including
appropriate self insurance) as may be required by law and such other insurance,
to such extent and against such hazards and liabilities consistent with practice
on the Issue Date, as the Company in its reasonable and good faith judgment
determines is required, taking into account its business and financial
condition.

          (c)  The Company shall, and shall cause each of its Subsidiaries to,
keep proper books of record and account, in which full and correct entries shall
be made of all business and financial transactions of the Company and each
Subsidiary of the Company and reflect on its financial statements adequate
accruals and appropriations to reserves, all in accordance with generally
accepted accounting principles consistently applied to the Company and its
Subsidiaries taken as a whole.

          (d)  The Company shall and shall cause each of its Subsidiaries to
comply with all statutes, laws, ordinances, or government rules and regulations
to which it is subject, non-compliance with which would materially adversely
affect the business, earnings, properties, assets or financial condition of the
Company and its Subsidiaries taken as a whole.

          SECTION 4.6  Compliance Certificates.

          (a)  The Company shall deliver to the Trustee, within 120 days after

the supervision of the signing Officers with a 
<PAGE>
 
                                     -48-

fulfilled its obligations under this Indenture and the Securities, and (ii)
that, to the knowledge of such Officer, no Default or Event of Default has
occurred (or, if a Default or Event of Default shall have occurred, describing
all such Defaults or Events of Default of which such Officer may have knowledge,
their status and what action the Company is taking or proposes to take with
respect thereto). The first certificate to be delivered pursuant to this Section
4.6(a) shall be for the first Fiscal Year of the Company ending after the Issue
Date.

          (b)  So long as not contrary to the then current recommendations of
the American Institute of Certified Public Accountants, the Company shall cause
its independent public accountants to deliver to the Trustee within 120 days
after the end of each Fiscal Year a written statement by such accountants
stating (A) that their audit examination has included a review of the relevant
provisions of this Indenture and the Securities as they relate to accounting
matters, and (B) whether, in connection with their audit examination, any
Default or Event of Default has come to their attention and if such a Default or
Event of Default has come to their attention, specifying the nature and period
of existence thereof, provided that, without any restriction as to the scope of
the audit examination, such independent certified public accountants shall not
be liable by reason of any failure to obtain knowledge of any such Default or
Event of Default that would not be disclosed in the course of an audit
examination conducted in accordance with generally accepted auditing standards.

          (c)  The Company will, so long as any of the Securities are
outstanding, deliver to the Trustee, promptly after any Officer becoming aware
of (i) any Default, Event of Default or default in the performance of any
covenant, agreement or condition contained in the Securities or this Indenture
or (ii) any event of default under any other Indebtedness referred to in Section
6.1(a)(v), an Officers' Certificate specifying such Default, Event of Default,
default or event of default and what action the Company is taking or proposes to
take with respect thereto.

          SECTION 4.7  Reports.

          So long as any security is outstanding, the Company will file with the
Commission and, within 15 days after it files them with the Commission, file
with the Trustees and mail or cause the Trustees to mail to the Holders at their
addresses as set forth in the register of the Securities copies of the annual
reports and of the information, documents and other reports which the Company is
required to file with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act or which the Company would be required to file with the Commission

In addition, the Company shall cause its annual report to stockholders and any
quarterly or other financial reports furnished to its stockholders generally to

available to the Company's stockholders, to the Holders at their addresses as
set forth in the register of Securities.

          After the Securities have been assigned an Investment Grade rating by
both Rating Agencies, the Company will no longer be subject to Sections 4.9,

     required to be paid in connection with such refunding pursuant to the terms
     of the Indebtedness refunded or the amount of any premium reasonably
     determined by the Company as necessary to accomplish such refunding by

     subordinate in right of payment to the Securities, such refunding
     Indebtedness is subordinate in right of payment to the Securities on terms

          The Company and each Subsidiary Guarantor covenants (to the extent
that it may lawfully do so) that it will not at any time insist upon, plead, or
in any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law or any usury law or other law that would prohibit or forgive the
Company or such Subsidiary Guarantor from paying all or any portion of the
principal of or interest on the Securities as contemplated herein or in the
Securities, wherever enacted, now or at any time hereafter in force, or that may
affect the covenants or the performance of this Indenture; and (to the extent
that it may lawfully do so) the Company and each Subsidiary Guarantor hereby
expressly waives all benefit or advantage of any such law, and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

any Subsidiary (an "Affiliate Transaction"), other than Affiliate Transactions
that are on terms that are fair and reasonable to the Company or such Restricted

of the Company from an unaffiliated party; provided, that if the Company or any
Restricted Subsidiary of the Company enters into an Affiliate Transaction or
series of Affiliate Transactions involving or having an aggregate value of more

pany's Board of Directors or senior management; (f) any agreement as in effect

ordinary course of business (including, without limitation, pursuant to joint
venture agreements) and otherwise in compliance with the terms of this Indenture
which are fair to the Company or its Restricted Subsidiaries, in the reasonable
determination of the senior management of the Company, or are on terms at least
as favorable as might reasonably have been obtained at such time from an
unaffiliated party; and (j) any employment or compensation arrangement entered
into by the Company or any of its Restricted Subsidiaries in the ordinary course
of business that is not otherwise prohibited by the Indenture.

          After the Securities have been assigned an Investment Grade rating by
both Rating Agencies, and notwithstanding that the Securities may later cease to
have an Investment Grade rating, the Company will not be subject to the
provisions of this Section 4.12; provided, that no Default has occurred and is
continuing at the time the Securities have been assigned such rating.

          SECTION 4.13  Limitation on Liens.

          The Company will not, and will not cause or permit any of its

anticipation of, the incurrence of such Acquired

                                     -56-

Indebtedness by the Company, and provided, further that such Liens in respect of
such Acquired Indebtedness do not extend to or cover any property or assets of

          SECTION 4.14  Limitation on Payment Restrictions Affecting Restricted
                        Subsidiaries.

          The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create or suffer to exist or
allow to become effective any consensual encumbrance or restriction of any kind
on the ability of any such Restricted Subsidiary to (i) pay dividends, in cash
or otherwise, or make other payments or distributions on its Capital Stock or

          After the Securities have been assigned an Investment Grade rating by
both Rating Agencies, and notwithstanding that the Securities may later cease to
have an Investment Grade rating, the Company will not be subject to the
provisions of this Section 4.14; provided, that no Default has occurred and is
continuing at the time the Securities have been assigned such rating.

          SECTION 4.15  Limitation on Guarantees by Restricted Subsidiaries.

          The Company shall not cause or permit any of its Restricted
Subsidiaries, directly or indirectly, to guarantee the payment of any
Indebtedness of the Company unless such Restricted Subsidiary of the Company
simultaneously executes and delivers a supplemental indenture (the substantive
provisions of which are in Exhibit B hereto) to this Indenture providing for the
guarantee of payment of the Securities (a "Subsidiary Guarantee") by such
Restricted Subsidiary of the Company (a "Subsidiary Guarantor"); provided, any
guarantee by a Subsidiary Guarantor of such other Indebtedness (A) (1) (X) is
unsecured or (Y) is secured and (I) in the case of any such guarantee of
Indebtedness of the Company ranking pari passu with the Securities, the
Subsidiary Guarantee is secured equally and ratably with any Liens securing such
guarantee and (II) in the case of any such guarantee of Indebtedness of the
Company subordinated to the Securities, the Subsidiary Guarantee is secured on a
basis ranking prior to the Liens securing such guarantee and (2) (X) in the case
of any such guarantee of Indebtedness of the Company subordinated or junior to
the Securities (whether pursuant to its terms or by operation of law), such
guarantee is subordinated pursuant to a written agreement to the Subsidiary
Guarantee at least to the same extent and in the same manner as such other
Indebtedness is subordinated to the Securities, or (Y) the Subsidiary Guarantee
is not subordinated or junior to any Indebtedness of such Subsidiary Guarantor;
and (B) such Subsidiary Guarantor waives, and agrees it will not in any manner
whatsoever claim or take the benefit or advantage of, any rights of
reimbursement, indemnity or subrogation or any other rights against the Company
or any other Subsidiary of the Company as a result of any payment by it under
such Subsidiary Guarantees.  Notwithstanding the foregoing, any Subsidiary
Guarantee shall provide by its terms that it shall be automatically and
unconditionally released and discharged upon either (A) the unconditional
release or discharge of such Subsidiary Guarantor's guarantees of all other
Indebtedness of the Company (other than a release resulting from payment under
such Subsidiary Guarantor's guarantees) or (B) any sale, exchange or transfer,
to any Person not an Affiliate of the Company, of all (but not less than all) of
the Capital Stock of such Subsidiary Guarantor, or all or substantially all of
the assets of such Subsidiary Guarantor, pursuant to a transaction which is in
compliance with all of the terms of this Indenture.

          The supplemental indenture shall supplement this Indenture by, among
other things, creating an additional Article XI applicable to such Subsidiary
Guarantor and any other Subsidiary Guarantors in the form set forth in Exhibit B
hereto and, in connection 
<PAGE>
 
                                     -58-

with the execution and delivery of the supplemental indenture, such Subsidiary
Guarantor shall execute and deliver a Guarantee substantially in the form of
Exhibit C hereto. Such Article XI shall not become effective until the
provisions of Section 12.2 have been complied with.

          Notwithstanding the foregoing, any Subsidiary Guarantee will be
subject to release under the conditions described in Section 11.4 of Exhibit B
hereto.

          SECTION 4.16  [Reserved]

          SECTION 4.17  Limitation on Preferred Stock of Restricted
                        Subsidiaries.

          The Indentures will provide that the Company will not cause or permit
any of its Restricted Subsidiaries to issue any Preferred Stock other than to
the Company or to another Restricted Subsidiary.

          After the Securities have been assigned an Investment Grade rating by
both Rating Agencies, and notwithstanding that the Securities may later cease to
have an Investment Grade rating, the Company will not be subject to the
provisions of this Section 4.17; provided, that no Default has occurred and is
continuing at the time the Securities have been assigned such rating.

          SECTION 4.18  Limitation on Restricted Payments.

          The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to directly or indirectly, (i) declare or pay any
dividend, or make any distribution of any kind or character (whether in cash,
property or securities), in respect of any class of its Capital Stock or to the
holders thereof in their capacity as stockholders, excluding any (x) dividend or
distributions payable solely in shares of its Qualified Capital Stock or in
options, warrants or other rights to acquire its Qualified Capital Stock or (y)
in the case of any Restricted Subsidiary of the Company, dividends or
distributions payable to the Company or a Restricted Subsidiary of the Company;
(ii) purchase, redeem, or otherwise acquire or retire for value shares of
Capital Stock of the Company or a Restricted Subsidiary of the Company, any
securities convertible or exchangeable into shares of Capital Stock of the
Company or a Restricted Subsidiary of the Company or any options, warrants or
rights to purchase or acquire shares of Capital Stock of the Company or a
Restricted Subsidiary of the Company, excluding any such shares of Capital
Stock, options, warrants, rights or securities which are owned by the Company or
a Restricted Subsidiary of the Company; (iii) make any Investment (other than a
Permitted Investment) in, or payment on a guarantee of any obligation of, any
Person; or (iv) redeem, defease, repurchase, retire or 
<PAGE>
 
                                     -59-

otherwise acquire or retire for value, prior to any scheduled maturity,
repayment or sinking fund payment, Indebtedness which is subordinate in right of
payment to the Securities (each of the transactions described in clauses (i)
through (iv) (other than any exception to any such clause) being a "Restricted
Payment") if at the time thereof:

          (1)  an Event of Default, or an event that with the passing of time or
     giving of notice, or both, would constitute an Event of Default, shall have
     occurred and be continuing, or

          (2)  upon giving effect to such Restricted Payment, the Company could
     not incur at least $1.00 of additional Indebtedness pursuant to the terms
     of this Indenture described in clause (i) of Section 4.9, or

          (3)  upon giving effect to such Restricted Payment, the aggregate of
     all Restricted Payments made on or after the Issue Date exceeds the sum
     (without duplication) of: (a) 50% of cumulative Consolidated Net Income of
     the Company (or, in the case cumulative Consolidated Net Income of the
     Company shall be negative, less 100% of such deficit) for the period
     (treated as an accounting period) from the Issue Date through the last day
     of the Company's most recently ended fiscal quarter for which financial
     statements are available, plus (b) 100% of the aggregate net cash proceeds
     received after the Issue Date, including the fair market value of readily
     marketable securities from the issuance of Qualified Capital Stock of the
     Company and warrants, rights or options on Qualified Capital Stock of the
     Company (other than in respect of any such issuance to a Subsidiary of the
     Company) and the principal amount of Indebtedness of the Company or a
     Subsidiary of the Company that has been converted into or exchanged for
     Qualified Capital Stock of the Company which Indebtedness was incurred
     after the Issue Date; plus (c) in the case of the disposition or repayment
     of any Investment constituting a Restricted Payment made after the Issue
     Date, an amount equal to the lesser of the return of capital with respect
     to such Investment and the cost of such Investment, in either case, less
     the cost of the disposition of such Investment; provided, that at the time
     any such Investment is made the Company delivers to the Trustee a
     resolution of the Board of Directors of the Company to the effect that, for
     purposes of this Section 4.18, such Investment constitutes a Restricted
     Payment made after the Issue Date; plus (d) an amount equal to the sum of
     (i) the net reduction in Investments in Unrestricted Subsidiaries resulting
     from the receipt of dividends, repayments of loans or advances or other
     transfers of assets or proceeds from the disposition of Capital Stock or
     other distributions or payments, in each case to the Company or any
     Restricted Subsidiary from, or with respect to, interests in Unrestricted
     Subsidiaries, and (ii) the portion (proportionate to the Company's equity
     interest in such Subsidiary) of the fair market value of the net assets of
     an Unrestricted Subsidiary at the time such Unrestricted Subsidiary is
     designated a 
<PAGE>
 
                                     -60-

     Restricted Subsidiary; provided, that the foregoing sum shall not exceed,
     in the case of any Unrestricted Subsidiary, the amount of Investments
     previously made (and treated as a Restricted Payment) by the Company or any
     Restricted Subsidiary in such Unrestricted Subsidiary subsequent to the
     Issue Date; plus (e) $25.0 million. For purposes of determining the amount
     expended for Restricted Payments under this clause (3), property other than
     cash shall be valued at its fair market value.

          Notwithstanding the foregoing, the provisions set forth in the
immediately preceding paragraph will not prohibit (i) any dividend on any class
of Capital Stock of the Company or any of its Restricted Subsidiaries paid
within 60 days after the declaration thereof if, on the date when the dividend
was declared, the Company or any of its Restricted Subsidiaries, as the case may
be, could have paid such dividend in accordance with the provisions of this
Indenture, (ii) the renewal, extension, refunding or refinancing of any
Indebtedness otherwise permitted pursuant to the terms of this Indenture

into Qualified Capital Stock of the Company, (iv) any Restricted Payments,
including loans or other advances made pursuant to any employee benefit plans
(including plans for the benefit of directors) or employment agreements or other
compensation arrangements, in each case as approved by the Board of Directors of
the Company in its good faith judgment, (v) so long as no Default or Event of
Default has occurred and is continuing, any Investment made with the proceeds of
a substantially concurrent sale of Qualified Capital Stock of the Company;
provided, that the proceeds of such sale of Qualified Capital Stock shall not be
(and have not been) included in clause (3) of the preceding paragraph, (vi) the
redemption, repurchase, retirement or other acquisition of any Capital Stock of
the Company in exchange for or out of the net cash proceeds of the substantially
concurrent sale (other than to a Restricted Subsidiary of the Company) of
Qualified Capital Stock of the Company; provided, that the proceeds of such sale
of Capital Stock shall not be (and have not been) included in clause (3) of the
preceding paragraph, (vii) so long as no Event of Default has occurred and is
continuing, the redemption, repurchase, retirement or other acquisition of any
Subordinated Indebtedness of the Company in exchange for or out of the net cash
proceeds of the substantially concurrent sale (other than to a Subsidiary of the
Company) of Qualified Capital Stock of the Company; provided, that the proceeds
of such sale of Qualified Capital Stock shall not be (and have not been)
included in clause (3) of the preceding paragraph, (viii) the purchase of Senior
Subordinated Notes pursuant to an Offer to Purchase required by Section 4.19 or
Section 4.11 of the Senior Subordinated Note Indenture; provided, that no such
purchase shall be permitted until all Securities validly tendered pursuant to

purchased by the Company, (ix) the redemption, retirement or repurchase of the
Company's outstanding Series G Convertible Preferred Stock out of the net
proceeds of the Offerings, (x) Investments in Navistar Financial Corporation

Agreement, (xi) the declaration and payment of dividends to holders of any class
of Preferred Stock issued after the Issue Date; provided, that at the time of
the issuance of such Preferred Stock, the Company, after giving pro forma effect
to such issuance, would have been able to incur at least $1.00 of additional
Indebtedness pursuant to the terms of the Indentures described in clause (i) of
Section 4.9; (xii) so long as no Event of Default has occurred and is
continuing, any purchase or redemption or other retirement for value of Capital
Stock of the Company required pursuant to any shareholders agreement, management
agreement or employee stock option agreement in accordance with the provisions
of any such arrangement in an amount not to exceed $10.0 million in the
aggregate; (xiii) repurchases of Capital Stock deemed to occur upon the exercise
of stock options if such Capital Stock represents a portion of the exercise
price thereof; (xiv) payments not to exceed $500,000 per annum in the aggregate
to enable the Company to make payments to holders of its Capital Stock in lieu
of issuance of fractional shares of its Capital Stock; (xv) so long as no Event
of Default has occurred and is continuing, the repurchase of any shares of Class
B Common Stock or Common Stock held by the Supplemental Trust; (xvi) so long as
no Event of Default has occurred and is continuing, the redemption of any stock
purchase rights under a rights plan in an aggregate amount not to exceed $1.0
million; and (xvii) so long as no Event of Default has occurred and is

Restricted Subsidiaries as Unrestricted Subsidiaries; provided, that after
giving pro forma effect to such Investment, the Company could incur at least
$1.00 of additional Indebtedness pursuant to the terms of this Indenture
described in clause (i) of Section 4.9. Each Restricted Payment described in
clauses (i), (iv), (x), (xii) and (xv) of the previous sentence shall be taken
into account (and the Restricted Payments described in the remaining clauses
shall not be taken into account) for purposes of computing the aggregate amount
of all Restricted Payments made pursuant to clause (3) of the preceding
paragraph.

          After the Securities have been assigned an Investment Grade rating by
both Rating Agencies, and notwithstanding that the Securities may later cease to
have an Investment Grade rating, the Company will not be subject to the
provisions of this Section 4.18; provided, that no Default has occurred and is
continuing at the time the Securities have been assigned such rating.

          SECTION 4.19  Limitation on Certain Asset Dispositions.

          The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, make one or more Asset
Dispositions unless:  (i) the Company or the Restricted Subsidiary, as the case
may be, receives consideration for such Asset Disposition at least equal to the
fair market value of the assets sold or disposed of (as determined in good faith
by the Company); (ii) not less than 75% of the consideration for the disposition
consists of cash or readily marketable cash equivalents or the assumption of
<PAGE>
 
                                      -62-

Indebtedness (other than non-recourse Indebtedness or any Indebtedness
subordinated to the Securities) of the Company or such Restricted Subsidiary or
other obligations relating to such assets (and release of the Company or such
Restricted Subsidiary from all liability on the Indebtedness or other
obligations assumed); and (iii) all Net Available Proceeds, less any amounts
invested or committed to be invested within 360 days of such Asset Disposition
in assets related to the business of the Company (including capital expenditures
or the Capital Stock of another Person (other than the Company or any Person
that is a Restricted Subsidiary of the Company immediately prior to such
investment); provided, that immediately after giving effect to any such
investment (and not prior thereto) such Person shall be a Restricted Subsidiary
of the Company), are applied, on or prior to the 360th day after such Asset
Disposition (unless and to the extent that the Company shall determine to make
an Offer to Purchase), either to (A) the permanent reduction and prepayment of
any Indebtedness of the Company (other than Indebtedness which is expressly
subordinate to the applicable issue of Notes) then outstanding (including a
permanent reduction of commitments in respect thereof) or (B) the permanent
reduction and repayment of any Indebtedness of any Restricted Subsidiary of the
Company then outstanding (including a permanent reduction of commitments in
respect thereof).  The 361st day after such Asset Disposition shall be deemed to
be the "Asset Sale Offer Trigger Date," and the amount of Net Available Proceeds
from Asset Dispositions otherwise subject to the preceding provisions not so
applied or as to which the Company has determined not to so apply shall be
referred to as the "Unutilized Net Available Proceeds." Within fifteen days
after the Asset Sale Offer Trigger Date, the Company shall make an Offer to
Purchase the outstanding applicable issue of Securities at a purchase price in
cash equal to 100% of their principal amount plus any accrued and unpaid
interest thereon to the Purchase Date.  Notwithstanding the foregoing, the
Company may defer making any Offer to Purchase outstanding Securities until
there are aggregate Unutilized Net Available Proceeds equal to or in excess of
$25.0 million (at which time, the entire Unutilized Net Available Proceeds, and
not just the amount in excess of $25.0 million, shall be applied as required
pursuant to this paragraph).  Pending application of the Unutilized Net
Available Proceeds pursuant to this covenant, such Unutilized Net Available
Proceeds shall be invested in Permitted Investments of the types described in
clauses (i), (ii) and (iii) of the definition of "Permitted Investments."

          If any Indebtedness of the Company or any of its Restricted
Subsidiaries ranking pari passu with the Securities requires that prepayment of,
or an offer to prepay, such Indebtedness be made with any Net Available
Proceeds, the Company may apply such Net Available Proceeds pro rata (based on
the aggregate principal amount of the Securities then outstanding and the
aggregate principal amount (or accreted value, if less) of all such other
Indebtedness then outstanding) to the making of an Offer to Purchase the
Securities in accordance with the foregoing provisions and the prepayment or the
offer to prepay such pari passu Indebtedness.  Any remaining Net Available
Proceeds following the completion 
<PAGE>
 
                                      -63-

of the required Offer to Purchase may be used by the Company for any other
purpose (subject to the other provisions of the Indentures) and the amount of
Net Available Proceeds then required to be otherwise applied in accordance with
this covenant shall be reset to zero, subject to any subsequent Asset
Disposition. These provisions will not apply to a transaction consummated in
compliance with Article V.

          Notwithstanding the foregoing, the provisions of this covenant shall
not apply to any Sale/Leaseback Transaction with respect to the purchase of
tooling and related manufacturing equipment in the ordinary course of business
consistent with past practices.

          In the event that the Company makes an Offer to Purchase the
Securities, the Company shall comply with any applicable securities laws and
regulations, including any applicable requirements of Section 14(e) of, and Rule
14e-1 under, the Exchange Act and any violation of the provisions of this
Indenture relating to such Offer to Purchase occurring as a result of such
compliance shall not be deemed an Event of Default or an event that with the
passing of time or giving of notice, or both, would constitute an Event of
Default.

          After the Securities have been assigned an Investment Grade rating by
both Rating Agencies, and notwithstanding that the Securities may later cease to
have an Investment Grade rating, the Company will not be subject to the
provisions of this Section 4.19; provided, that no Default has occurred and is
continuing at the time the Securities have been assigned such rating.

          SECTION 4.20  Limitation on Sale/Leaseback Transactions.

          The Company shall not, and shall not cause or permit any Restricted
Subsidiary to, enter into any Sale/Leaseback Transaction with respect to any
property unless (i) the Company or such Restricted Subsidiary would be entitled
to (A) incur Indebtedness in an amount equal to the Attributable Indebtedness
with respect to such Sale/Leaseback Transaction pursuant to clause (i) of
Section 4.9 and (B) create a Lien on such property securing such Attributable
Indebtedness without securing the Securities pursuant to Section 4.13 and (ii)
the net proceeds received by the Company or any Restricted Subsidiary in
connection with such Sale/Leaseback Transaction are at least equal to the fair
value (as determined by the Board of Directors) of such property and (iii) the
Company applies the proceeds of such transaction in compliance with Section
4.19.  Notwithstanding the foregoing, the provisions of this covenant shall not
prohibit the Company or any Restricted Subsidiary from entering into any
Sale/Leaseback Transaction with respect to the purchase of tooling and related
manufacturing equipment in the ordinary course of business consistent with past
practices.

Section 4.8 herein); and (iv) the Company or such Person shall have delivered to
the Trustee (A) an Officers' Certificate and an Opinion of Counsel, each stating

clause (ii) of the above, (y) a series of transactions involving the sale of

          SECTION 6.1  Events of Default.

     or in the Securities and failure to remedy such default or breach within a
     period of 30 days after written notice from the Trustee or the Holders of
     at least 25% in aggregate principal amount of the then outstanding
     Securities; or

             (v)    default under any mortgage, indenture or instrument under
     which there may be issued or by which there may be secured or evidenced any
     Indebtedness for money borrowed by the Company or any Subsidiary of the
     Company (or the payment of which is guaranteed by the Company or any
     Restricted Subsidiary of the Company), which default results in the
     acceleration of such Indebtedness prior to its express maturity and the
     principal amount of any such Indebtedness, together with
<PAGE>
 
                                      -67-

     the principal amount of any other such Indebtedness the maturity of which
     has been so accelerated, aggregates $20.0 million or more and such
     acceleration has not been rescinded or annulled or such Indebtedness
     discharged in full within 30 days; or

             (vi)   the entry by a court of competent jurisdiction of one or
     more judgments, orders or decrees against the Company or any Subsidiary of
     the Company or any of their respective property or assets in an aggregate
     amount in excess of $20.0 million, which judgments, orders or decrees have
     not been vacated, discharged, satisfied or stayed pending appeal within 30
     days from the entry thereof and with respect to which legal enforcement
     proceedings have been commenced; or

             (vii)  the Company or any Material Subsidiary pursuant to or within
     the meaning of any Bankruptcy Law:

                    (A) commences a voluntary case or proceeding, or

                    (B) consents to the entry of an order for relief against it
          in an involuntary case or proceeding, or

                    (C) consents to the appointment of a Custodian of it or for
          all or substantially all of its property, or

                    (D) makes a general assignment for the benefit of its
          creditors, or

          relief, or

                    (F) shall admit in writing its inability to pay its debts
          generally; or

             (viii) a court of competent jurisdiction enters an order or decree
     under any Bankruptcy Law that:

                    (A) is for relief against the Company or any of its Material
          Subsidiaries in an involuntary case or proceeding, or

                    (B) appoints a Custodian of the Company or any of its

          or

                    (C) orders the liquidation of the Company or any of its

<PAGE>
 
                                      -68-

          (b)  For purposes of this Section 6.1, the term "Custodian" means any
receiver, trustee, assignee, liquidator, sequestrator or similar official
charged with maintaining possession or control over property for one or more
creditors.

          SECTION 6.2  Acceleration.

          If an Event of Default (other than an Event of Default relating to the
Company and specified in clauses (vii) or (viii) of Section 6.1(a)) occurs and
is continuing, the Trustee or Holders of at least 25% in aggregate principal
amount of the then outstanding Securities may, by written notice to the Company
(and to the Trustee, if given by the Holders), and the Trustee shall upon the
request of Holders of not less than 25% in aggregate principal amount of the
outstanding Securities, by written notice to the Company, declare the unpaid
principal of, premium, if any, and accrued and unpaid interest on all the
Securities then outstanding to be due and payable immediately, and the same
shall become immediately due and payable.  If an Event of Default relating to
the Company and specified in clauses (vii) or (viii) of Section 6.1(a) occurs
and is continuing, the unpaid principal of, premium and accrued and unpaid
interest on all the Securities shall ipso facto become and be immediately due
and payable without any declaration or other act on the part of the Trustee or
any Holder.  The Holders of, in the aggregate, at least a majority in principal
amount of the then outstanding Securities by notice to the Trustee may rescind
an acceleration and its consequences if all existing Events of Default (except
the nonpayment of principal and interest on the Securities that has become due
solely as a result of the acceleration of the Securities) have been cured or
waived and if the rescission would not conflict with any judgment or decree. No
such rescission shall affect any subsequent default or impair any right
consequent thereto.

          SECTION 6.3  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 Securities or to enforce the
performance of any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which such judgment has been
recovered.
<PAGE>
 
                                      -69-

          SECTION 6.4  Waiver of Past Default.

          Subject to Sections 6.7 and 9.2, the Holders of, in the aggregate, at
least a majority in principal amount of the then outstanding Securities by
notice to the Trustee may waive an existing Default or Event of Default and its
consequences, except a Default or Event of Default specified in Section
6.1(a)(i) or (ii) or a Default or Event of Default in respect of any provision
hereof which cannot be modified or amended without the consent of the Holder so
affected pursuant to Section 9.2.  When a Default or Event of Default is so
waived, it shall be deemed cured and cease to exist; but no such waiver shall
extend to any subsequent or other Default or Event of Default or impair any
right consequent thereto.

          SECTION 6.5  Control by Majority.

          The Holders of a majority in principal amount of the then outstanding
Securities may (i) 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 6.3, and (ii) direct the Trustee to notify each trustee under any
instrument governing the rights of holders of Indebtedness subordinated in right
of payment to the Securities for the purpose of effecting the payment blockage
provisions thereunder.  The Trustee may refuse, however, to follow any direction
that conflicts with law, the Securities or this Indenture, or that the Trustee
determines may be unduly prejudicial to the rights of another Securityholder
(provided, however, that subject to Section 7.1, the Trustee shall have no duty
or obligation to ascertain whether or not such direction is unduly prejudicial
to such Securityholder), that may involve the Trustee in personal liability or
if the Trustee determines that it does not have adequate indemnification against
any loss or expense, provided that the Trustee may take any other action deemed
proper by the Trustee which is not inconsistent with such direction.

          SECTION 6.6  Limitation on Suits.

          A Securityholder may not pursue any remedy with respect to this
Indenture or the Securities unless:

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

          (b)  the Holders of at least 25% in principal amount of the then
     outstanding Securities make a written request to the Trustee to pursue a
     remedy;
<PAGE>
 
                                      -70-

          (c)  such Holder or Holders offer and, if requested, provide to the
     Trustee indemnity reasonably satisfactory to the Trustee against any loss,
     liability or expense;

          (d)  the Trustee does not comply with the request within 30 days after
     receipt of the request; and

          (e)  during such 30-day period the Holders of at least a majority in
     principal amount of the then outstanding Securities do not give the Trustee
     a direction which is inconsistent with the request.

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

          SECTION 6.7  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 Security, on or
after the respective due dates expressed in the Security, or to bring suit for
the enforcement of any such payment on or after such respective dates, is
absolute and unconditional and shall not be impaired or affected without the
consent of such Holder.

          SECTION 6.8  Collection Suit by Trustee.

          If an Event of Default specified in Section 6.1(a)(i) or (ii) occurs
and is continuing, the Trustee may recover judgment in its own name and as
trustee of an express trust against the Company or any other obligor on the
Securities for the whole amount of principal and accrued interest remaining
unpaid, together with interest overdue on principal and, to the extent that
payment of such interest is lawful, interest on overdue installments of
interest, in each case at the Interest Rate 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 6.9  Trustee May File Proofs of Claim.

          The Trustee shall be entitled and empowered to 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, disbursements and advances of the Trustee, its agents
and counsel) and the Securityholders allowed in any judicial proceedings
relative to the Company or any of its Subsidiaries (or any other obligor upon
the Securities), its creditors or its property and shall be entitled and
empowered to collect and receive any monies or other property payable or
deliverable on any such claims 
<PAGE>
 
                                      -71-

and to distribute the same, and any Custodian in any such judicial proceedings
is hereby authorized by each Securityholder 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 Securityholders, to pay to the Trustee any amount due to it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agent and counsel, and any other amounts due the Trustee under
Section 7.7. Nothing herein contained shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Securityholder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Securityholder in any such proceeding.

          SECTION 6.10  Priorities.

          If the Trustee collects any money pursuant to this Article VI, it
shall pay out such money in the following order:

     First: to the Trustee for all costs and expenses of collection and for all
     other amounts due under Section 7.7;

     Second: to Holders for interest accrued on the Securities, ratably, without
     preference or priority of any kind, according to the amounts due and
     payable on the Securities for interest; and

     Third: to Holders for principal amounts owing under the Securities,
     ratably, without preference or priority of any kind, according to the
     amounts due and payable on the Securities for principal.

          The Trustee, upon prior written notice to the Company, may fix a
record date and payment date for any payment to Securityholders 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, 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 6.7, or a suit by any Holder, or group of Holders, holding
in the aggregate more than 10% in principal amount of the outstanding
Securities.
<PAGE>
 
                                      -72-

          SECTION 6.12  Rights and Remedies Cumulative.

          No right or remedy herein conferred upon or reserved to the Trustee or
to the Holders is intended to be exclusive of any other right or remedy, and
every remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

          SECTION 6.13  Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein.  Every right and remedy given by this Article 6 or by
law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

          SECTION 6.14  Restoration of Rights and Remedies.

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture 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 case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
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 VII

                                    TRUSTEE

          SECTION 7.1  Duties of Trustee.

          (a)  If an Event of Default known to the Trustee 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 their exercise
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:
<PAGE>
 
                                      -73-

             (i)    The Trustee need perform only those duties as are
     specifically set forth in this Indenture or the TIA and no others and no
     implied covenants or obligations shall be read into this Indenture against
     the Trustee.

             (ii)   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 opinions which by any provision
     hereof are specifically required to be furnished to the Trustee, the
     Trustee shall examine such certificates and opinions to determine whether
     or not they conform to the requirements of this Indenture.

          (c)  Notwithstanding anything to the contrary herein contained, the
Trustee may not be relieved from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that:

             (i)    This paragraph does not limit the effect of paragraph (b) of
     this Section 7.1.

             (ii)   The Trustee shall not be liable for any error of judgment
     made in good faith by a Trust Officer, unless it is proved that the Trustee
     was negligent in ascertaining the pertinent facts.

             (iii)  The Trustee shall not be liable with respect to any action
     it takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Sections 6.2, 6.4 and 6.5.

          (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 of any of its duties hereunder or in the exercise of any of its
rights or powers 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 7.1.

          (f)  The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.
Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by law.

          SECTION 7.2  Rights of Trustee.

          Subject to Section 7.1:

          (a)  The Trustee may rely and shall be protected in acting or
     refraining from acting upon any document reasonably believed by it to be
     genuine and to have been signed or presented by the proper Person.  The
     Trustee shall not be bound to make any investigation into the facts or
     matters stated in any resolution, certificate, statement, instrument,
     opinion, report, notice, request, direction, consent, order, bond,
     debenture, note, other evidence of indebtedness 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, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled during normal business hours and upon reasonable advance
     notice to the Company to examine the books, records and premises of the
     Company, personally or by agent or attorney.

          (b)  Before the Trustee acts or refrains from acting with respect to
     any matter contemplated by this Indenture, it may require an Officers'
     Certificate or an Opinion of Counsel, which shall conform to the provisions
     of Section 10.5.  The Trustee shall not be liable for any action it takes
     or omits to take in good faith in reliance on such certificate or opinion.

          (c)  The Trustee may act through its attorneys and agents and shall
     not be responsible for the misconduct or negligence of any agent (other
     than the negligence or willful misconduct of an agent who is an employee of
     the Trustee) appointed with due care.

          (d)  The Trustee shall not be liable for any action it takes or omits
     to take in good faith and without negligence which it reasonably believes
     to be authorized or within its rights or powers conferred upon it by this
     Indenture or the TIA.

          (e)  Before the Trustee acts or refrains from acting, it may consult
     with counsel and the advice or opinion of such counsel as to matters of law
     shall be full and complete authorization and protection from liability in
     respect of any action taken, omitted or suffered by it hereunder in good
     faith and in accordance with the advice or opinion of such counsel.

          (f)  The Trustee shall not be required to give any bond or surety in
     respect of the performance of its powers and duties hereunder.
<PAGE>
 
                                      -75-

          (g)  The permissive rights of the Trustee to do things enumerated in
     this Indenture shall not be construed as a duty.

          (h)  The Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Securityholders unless such Securityholders shall have
     offered to the Trustee security or indemnity reasonable to it against the
     costs, expenses and liabilities that might be incurred by it in compliance
     with such request or direction.

          (i)  Except for (i) a default under Sections 6.1(a)(i) or (ii) hereof,
     or (ii) any other event of which the Trustee has "actual knowledge" and
     which event, with the giving of notice or the passage of time or both,
     would constitute an Event of Default under this Indenture, the Trustee
     shall not be deemed to have notice of any default or Event of Default
     unless specifically notified in writing of such event by the Company or the
     Holders of not less than 25% in aggregate principal amount of the
     Securities then outstanding; as used herein, the term "actual knowledge"
     means the actual fact or statement of knowing, without any duty to make any
     investigation with regard thereto.

          SECTION 7.3  Individual Rights of Trustee.

          The Trustee in its individual capacity or any other capacity may
become the owner or pledgee of Securities and may otherwise deal with the
Company, or its Subsidiaries and 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 is subject to Sections 7.10 and 7.11.

          SECTION 7.4  Trustee's Disclaimer.

          The Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Securities, it shall not
be accountable for the Company's use of the proceeds from the Securities or for
the use or application of any money received by any Paying Agent other than the
Trustee, and it shall not be responsible for any statement of the Company in
this Indenture or any other document in connection with the sale of the
Securities, or any statement in the Securities other than the Trustee's
certificate of authentication.

          SECTION 7.5  Notice of Defaults.

          If a Default or an Event of Default with respect to the Securities
occurs and is continuing and the Trustee receives written notice of such Default
or Event of Default, the Trustee shall mail to each Securityholder notice of the
Default or Event of Default 
<PAGE>
 
                                      -76-

within 60 days after the occurrence thereof in accordance with TIA (S)313(c).
Except in the case of a Default or an Event of Default in payment of principal
of or interest on any Security, including on acceleration, and the failure to
make payment when required by Section 4.11, and except in the case of a failure
to comply with Article V hereof, the Trustee may withhold the notice to the
Securityholders for a period not to exceed 60 days if and so long as a committee
of its Trust Officers in good faith determines that withholding the notice is in
the interest of Securityholders.

          SECTION 7.6  Reports by Trustee to Holders.

          To the extent required by TIA (S)313(a), within 45 days after June 1
of each year commencing with 1998 and for as long as there are Securities
outstanding hereunder, the Trustee shall mail to each Securityholder the
Company's brief report dated as of such date that complies with TIA (S)313(a).
The Trustee also shall comply with TIA (S)313(b) and TIA (S)313(c) and (d).  A
copy of such report at the time of its mailing to Securityholders shall be filed
with the SEC, if required, and each stock exchange, if any, on which the
Securities are listed.

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

          SECTION 7.7  Compensation and Indemnity.

          The Company shall pay to the Trustee, the Paying Agent and the
Registrar from time to time reasonable compensation for their respective
services rendered hereunder.  The Trustee's, the Paying Agent's and the
Registrar's compensation shall not be limited by any law on compensation of a
trustee of an express trust.  The Company shall reimburse the Trustee, the
Paying Agent and the Registrar upon request for all reasonable out-of-pocket
disbursements, expenses and advances (including reasonable fees and expenses of
counsel) incurred or made by each of them in connection with entering into this
Indenture the performance of its duties under this Indenture in addition to the
compensation for their respective services under this Indenture.  Such expenses
shall include the reasonable compensation, out-of-pocket disbursements and
expenses of the Trustee's, the Paying Agent's and the Registrar's agents and
counsel.

          The Company shall indemnify the Trustee, the Paying Agent and the
Registrar for, and hold each of them harmless against, any claim, demand,
expense (including but not limited to attorneys' fees and expenses), loss or
liability incurred by each of them arising out of or in connection with the
administration of this Indenture and their respective duties hereunder.  Each of
the Trustee, the Paying Agent and the Registrar shall notify the Company
promptly of any claim asserted against it for which it may seek indemnity.
How-

                                      -77-

ever, failure by the Trustee, the Paying Agent or the Registrar to so notify the
Company shall not relieve the Company of its obligations hereunder. The Company
need not reimburse any expense or indemnify against any loss or liability
incurred by the Trustee, the Paying Agent or the Registrar through the
Trustee's, the Paying Agent's or the Registrar's, as the case may be, own
willful misconduct or negligence.

          To secure the Company's payment obligations in this Section 7.7, each
of the Trustee, the Paying Agent and the Registrar shall have a lien prior to
the Securities on all money or property held or collected by it, in its capacity
as Trustee, Paying Agent or Registrar, as the case may be, except money or
property held in trust to pay principal of or interest on particular Securities.
Such lien shall survive the satisfaction and discharge of this Indenture.

          When any of the Trustee, the Paying Agent and the Registrar incurs
expenses or renders services after an Event of Default specified in Section
6.1(a)(vii) or (viii) occurs, the expenses and the compensation for the services
are intended to constitute expenses of administration under any Bankruptcy Law.

          SECTION 7.8  Replacement of Trustee.

          The Trustee may resign at any time 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
Securities may remove the Trustee by so notifying 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:

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

          (b)  the Trustee is adjudged a bankrupt or an insolvent;

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

          (d)  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 Trustee in such event being referred to
herein as the retiring Trustee), the Company 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 Securities may appoint a successor
Trustee to replace the successor Trustee appointed by the Company.
<PAGE>
 
                                      -78-

          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 7.7), 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
Securityholder.

          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 25% in principal amount of then outstanding Securities 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 Securityholder
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
7.8, the Company's obligations under Section 7.7 shall continue for the benefit
of the retiring Trustee.

          SECTION 7.9  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 or national banking association without any further act
shall be the successor Trustee, provided such corporation or national banking
association shall be otherwise qualified and eligible under this Article VII.

          SECTION 7.10  Eligibility; Disqualification.

          This Indenture shall always have a Trustee who satisfies the
requirements of TIA (S)310(a)(1) and (2).  The Trustee shall have a combined
capital and surplus of at least $200,000,000 as set forth in its most recent
published annual report of condition.  The Trustee shall comply with TIA
(S)310(b), provided 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. The provisions of TIA (S)310 shall apply to the Company,
as obligor of the Securities.

                                      -79-

          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. The
provisions of TIA (S)311 shall apply to the Company as obligor on the
Securities.

                                  ARTICLE VIII

                    SATISFACTION AND DISCHARGE OF INDENTURE

          SECTION 8.1  Termination of the Company's Obligations.

          The Company's obligations under the Securities and this Indenture
shall terminate, and the obligations of any Subsidiary Guarantor shall
terminate, except those obligations referred to in the penultimate paragraph of
this Section 8.1, if all Securities previously authenticated and delivered
(other than destroyed, lost or stolen Securities which have been replaced or
paid or Securities for whose payment money has theretofore been deposited with
the Trustee or the Paying Agent in trust or segregated and held in trust by the
Company and thereafter repaid to the Company, as provided in Section 8.4) have
been delivered to the Trustee for cancellation and the Company has paid all sums
payable by it hereunder, or if:

          (a)  all Securities have otherwise become due and payable hereunder;

          (b)  the Company shall have irrevocably deposited or caused to be
     deposited with the Trustee or a trustee satisfactory to the Trustee, 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 Holders for that purpose, cash or cash equivalents in such amount as
     is sufficient without consideration of reinvestment of such interest, to
     pay principal of, premium, if any, and interest on the outstanding
     Securities to maturity or redemption, provided that the Trustee shall have
     been irrevocably instructed to apply such cash or cash equivalents to the
     payment of said principal, premium, if any, and interest with respect to
     the Securities, and, provided, further, that from and after the time of
     deposit, the money deposited shall not be subject to the rights of holders
     of Senior Indebtedness of the Company or Guarantor Senior Indebtedness
     pursuant to the provisions of Article XI or Article XII;

          (c)  no Default or Event of Default with respect to this Indenture or
     the Securities shall have occurred and be continuing on the date of such
     deposit or shall oc-
<PAGE>
 
                                      -80-

     cur as a result of such deposit and such deposit will not result in a
     breach or violation of, or constitute a default under, any other instrument
     to which the Company is a party or by which it is bound;

          (d)  the Company shall have paid all other sums payable by it
     hereunder;

          (e)  the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent providing for the termination of the Company's and each
     Subsidiary Guarantor's obligation under the Securities and this Indenture
     have been complied with. Such Opinion of Counsel shall also state that such
     satisfaction and discharge does not result in a default under any Senior
     Indebtedness of the Company (if then in effect) or any other agreement or
     instrument then known to such counsel that binds or affects the Company.

          Notwithstanding the foregoing paragraph, the Company's obligations in
Sections 2.5, 2.6, 2.7, 2.8, 4.1, 4.2 and 7.7 and any Subsidiary Guarantor's
obligations in respect thereof shall survive until the Securities are no longer
outstanding.  After the Securities are no longer outstanding, the Company's
obligations in Sections 7.7, 8.4 and 8.5 and any Subsidiary Guarantor's
obligations in respect thereof shall survive.

          After such delivery or irrevocable deposit the Trustee upon request
shall acknowledge in writing the discharge of the Company's and any Subsidiary
Guarantor's obligations under the Securities and this Indenture except for those
surviving obligations specified above.

          SECTION 8.2  Legal Defeasance and Covenant Defeasance.

          (a)  The Company may, at its option and at any time, with respect to
the Securities, elect to have either paragraph (b) or paragraph (c) below be
applied to the outstanding Securities upon compliance with the conditions set
forth in paragraph (d).

          (b)  Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (b), the Company and any Subsidiary Guarantor shall
be deemed to have been released and discharged from its obligations with respect
to the outstanding Securities on the date the conditions set forth below are
satisfied (hereinafter, "legal defeasance").  For this purpose, such legal
defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by the outstanding Securities, which shall
thereafter be deemed to be "outstanding" only for the purposes of paragraph (c)
below and the other Sections of and matters under this Indenture referred to in
(i) and (ii) below, and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the 
<PAGE>
 
                                      -81-

Company, shall execute proper instruments acknowledging the same), and Holders
of the Securities and the Subsidiary Guarantees and any amounts deposited under
paragraph (d) below shall cease to be subject to any obligations to, or the
rights of, any holder of Senior Indebtedness of the Company or Guarantor Senior
Indebtedness under Article XI or otherwise, except for the following which shall
survive until otherwise terminated or discharged hereunder: (i) the rights of
Holders of outstanding Securities to receive solely from the trust fund
described in paragraph (d) below and as more fully set forth in such paragraph,
payments in respect of the principal of, premium, if any, and interest on such
Securities when such payments are due, (ii) the Company's obligations with
respect to such Securities under Sections 2.6, 2.7 and 4.2, and, with respect to
the Trustee, under Section 7.7 and any Subsidiary Guarantor's obligations in
respect thereof, (iii) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (iv) this Section 8.2 and Section 8.5. Subject to
compliance with this Section 8.2, the Company may exercise its option under this
paragraph (b) notwithstanding the prior exercise of its option under paragraph
(c) below with respect to the Securities.

          (c)  Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (c), the Company shall be released and discharged
from its obligations under any covenant contained in Article V and in Sections
4.5 through 4.9, 4.11 through 4.20 and Section 5.1 with respect to the
outstanding Securities on and after the date the conditions set forth below are
satisfied (hereinafter, "covenant defeasance"), and the Securities shall
thereafter be deemed to be not "outstanding" for the purpose of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"outstanding" for all other purposes hereunder and Holders of the Securities and
the Subsidiary Guarantees and any amounts deposited under paragraph (d) below
shall cease to be subject to any obligations to, or the rights of, any holder of
Senior Indebtedness of the Company or Guarantor Senior Indebtedness under
Article XI or otherwise.  For this purpose, such covenant defeasance means that,
with respect to the outstanding Securities, the Company and any Subsidiary
Guarantor may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in any such covenant, whether directly
or indirectly, by reason of any reference elsewhere herein to any such covenant
or by reason of any reference in any such covenant to any other provision herein
or in any other document and such omission to comply shall not constitute a
Default or an Event of Default under Section 6.1(a) (iv), but, except as
specified above, the remainder of this Indenture and such Securities shall be
unaffected thereby.

          (d)  The following shall be the conditions to application of either
paragraph (b) or paragraph (c) above to the outstanding Securities:
<PAGE>
 
                                      -82-

             (i)    the Company shall irrevocably have deposited or caused to be
     deposited with the Trustee as trust funds in trust for the purpose of
     making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of such Securities, (x)
     money in an amount or (y) direct non-callable obligations of, or non-
     callable obligations guaranteed by, the United States of America for the
     payment of which guarantee or obligation the full faith and credit of the
     United States is pledged ("U.S. Government Obligations") maturing as to
     principal, premium, if any, and interest in such amounts of money and at
     such times as are sufficient without consideration of any reinvestment of
     such interest, to pay principal of and interest on the outstanding
     Securities not later than one day before the due date of any payment, or
     (z) 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 and
     which shall be applied by the Trustee (or other qualifying trustee) to pay
     and discharge principal of, premium, if any, and interest on the
     outstanding Securities on the Maturity Date or otherwise in accordance with
     the terms of this Indenture and of such Securities, provided that the
     Trustee (or other qualifying trustee) shall have received an irrevocable
     written order from the Company instructing the Trustee (or other qualifying
     trustee) to apply such money or the proceeds of such U.S. Government
     Obligations to said payments with respect to the Securities;

             (ii)   no Default or Event of Default with respect to the
     Securities or this Indenture shall have occurred and be continuing
     immediately after giving effect to such deposit (or, insofar as Section
     6.1(a)(vii) or (viii) is concerned, at any time during the period ending on
     the 91st day after the date of such deposit (it being understood that this
     condition shall not be deemed satisfied until the expiration of such
     period); provided, however, that actions taken by the Company in connection
     with the creation of the trust fund into which funds for the purpose of
     defeasance of the Securities are deposited that are not in compliance with
     Sections 4.9, 4.13 and 4.14 as a result of the incurrence of indebtedness
     to create such trust fund deposit, in each case, shall not be deemed a
     Default or Event of Default under this Indenture);

             (iii)  such legal defeasance or covenant defeasance shall not cause
     the Trustee to have a conflicting interest with respect to any Securities
     of the Company or any Subsidiary Guarantor;

             (iv)   such legal defeasance or covenant defeasance shall not
     result in a breach or violation of, or constitute a Default or Event of
     Default under any agreement or instrument to which the Company or any
     Subsidiary Guarantor is a party or by which it is bound;
<PAGE>
 
                                      -83-

             (v)    in the case of an election under paragraph (b) above, the
     Company shall have delivered to the Trustee an Opinion of Counsel stating
     that (x) the Company has received from, or there has been published by, the
     Internal Revenue Service a ruling or (y) since the date of this Indenture,
     there has been a change in the applicable Federal income tax law, in either
     case to the effect that, and based thereon such opinion shall confirm that,
     the Holders of the outstanding Securities will not recognize income, gain
     or loss for Federal income tax purposes as a result of such legal
     defeasance and will be subject to Federal income tax on the same amounts,
     in the same manner and at the same times as would have been the case if
     such legal defeasance had not occurred;

             (vi)   in the case of an election under paragraph (c) above, the
     Company shall have delivered to the Trustee an Opinion of Counsel to the
     effect that the Holders of the outstanding Securities will not recognize
     income, gain or loss for Federal income tax purposes as a result of such
     covenant defeasance and will be subject to Federal income tax on the same
     amounts, in the same manner and at the same times as would have been the
     case if such covenant defeasance had not occurred;

             (vii)  in the case of an election under either paragraph (b) or (c)
     above, an Opinion of Counsel to the effect that, (x) the trust funds will
     not be subject to any rights of any holders of other Indebtedness,
     including, without limitation, Senior Indebtedness of the Company, and (y)
     after the 91st day following the deposit, the trust funds will not be
     subject to the effect of any applicable Bankruptcy Law, provided that if a
     court were to rule under any such law in any case or proceeding that the
     trust funds remained property of the Company, no opinion needs to be given
     as to the effect of such laws on the trust funds except the following:  (A)
     assuming such trust funds remained in the Trustee's possession prior to
     such court ruling to the extent not paid to Holders of Securities, the
     Trustee will hold, for the benefit of the Holders of Securities, a valid
     and enforceable security interest in such trust funds that is not avoidable
     in bankruptcy or otherwise, subject only to principles of equitable
     subordination, (B) the Holders of Securities will be entitled to receive
     adequate protection of their interests in such trust funds if such trust
     funds are used, and (C) no property, rights in property or other interests
     granted to the Trustee or the Holders of Securities in exchange for or with
     respect to any of such funds will be subject to any prior rights of any
     other person, subject only to prior Liens granted under Section 364 of
     Title 11 of the U.S.  Bankruptcy Code (or any section of any other
     Bankruptcy Law having the same effect), but still subject to the foregoing
     clause (B); and
<PAGE>
 
                                      -84-

             (viii)  the Company shall have delivered to the Trustee an
     Officers' Certificate and an Opinion of Counsel, each stating that (x) all
     conditions precedent provided for relating to either the legal defeasance
     under paragraph (b) above or the covenant defeasance under paragraph (c)
     above, as the case may be, have been complied with and (y) if any other
     Indebtedness of the Company shall then be outstanding or committed, such
     legal defeasance or covenant defeasance will not violate the provisions of
     the agreements or instruments evidencing such Indebtedness.

          (e)  All money and U.S. Government Obligations (including the proceeds
thereof) deposited with the Trustee pursuant to paragraph (d) above in respect
of the outstanding Securities shall be held in trust and applied by the Trustee,
in accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any Paying Agent (other than the Company or
any Affiliate of the Company) as the Trustee may determine, to the Holders of
such Securities of all sums due and to become due thereon in respect of
principal, premium and interest, but such money need not be segregated from
other funds except to the extent required by law.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to paragraph (d) above or the principal, premium, if any, and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding
Securities.

          Anything in this Section 8.2 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the request,
in writing, by the Company any money or U.S. Government Obligations held by it
as provided in paragraph (d) above which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount
thereof which would then be required to be deposited to effect an equivalent
legal defeasance or covenant defeasance.

          SECTION 8.3  Application of Trust Money.

          The Trustee shall hold in trust money or U.S. Government Obligations
deposited with it pursuant to Sections 8.1 and 8.2, and shall apply the
deposited money and the money from U.S. Government Obligations in accordance
with this Indenture to the payment of principal of, premium, if any, and
interest on the Securities.
<PAGE>
 
                                     -85-

          SECTION 8.4  Repayment to Company or Subsidiary Guarantors.

          Subject to Sections 7.7, 8.1 and 8.2, the Trustee shall promptly pay
to the Company, or if deposited with the Trustee by any Subsidiary Guarantor, to
such Subsidiary Guarantor, upon receipt by the Trustee of an Officers'
Certificate, any excess money, determined in accordance with Section 8.2, held
by it at any time.  The Trustee and the Paying Agent shall pay to the Company or
any Subsidiary Guarantor, as the case may be, upon receipt by the Trustee or the
Paying Agent, as the case may be, of an Officers' Certificate, any money held by
it for the payment of principal, premium, if any, or interest that remains
unclaimed for two years after payment to the Holders is required (unless
otherwise provided under operation of law), provided that the Trustee and the
Paying Agent before being required to make any payment may, but need not, at the
expense of the Company cause to be published once in a newspaper of general
circulation in The City of New York or mail to each Holder entitled to such
money notice that such money remains unclaimed and that after a date specified
therein, which shall be at least 30 days from the date of such publication or
mailing, any unclaimed balance of such money then remaining will be repaid to
the Company.  After payment to the Company or any Subsidiary Guarantor, as the
case may be, Securityholders entitled to money must look solely to the Company
for payment as general creditors unless an applicable abandoned property law
designates another person, and all liability of the Trustee or Paying Agent with
respect to such money shall thereupon cease.

          SECTION 8.5  Reinstatement.

          If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with this Indenture 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, then
and only then the Company's and each Subsidiary Guarantor's, if any, obligations
under this Indenture and the Securities shall be revived and reinstated as
though no deposit had been made pursuant to this Indenture until such time as
the Trustee is permitted to apply all such money or U.S. Government Obligations
in accordance with this Indenture, provided that if the Company or the
Subsidiary Guarantors, as the case may be, has made any payment of principal of,
premium, if any, or interest on any Securities because of the reinstatement of
its obligations, the Company or the Subsidiary Guarantors, as the case may be,
shall be, subrogated to the rights of the holders of such Securities to receive
such payment from the money or U.S. Government Obligations held by the Trustee

                                  ARTICLE IX


                      AMENDMENTS, SUPPLEMENTS AND WAIVERS

          SECTION 9.1  Without Consent of Holders.

          Without the consent of any Holders, the Company, when authorized by
resolutions of its Board of Directors (copies of which shall be delivered to the
Trustee) and the Trustee may amend, waive or supplement this Indenture or the
Securities without notice to or consent of any Holder for any of the following
purposes:

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

          (b)  to provide for uncertificated Securities in addition to or in
     place of certificated Securities;

          (c)  to comply with any requirements of the SEC under the TIA;

          (d)  to evidence the succession in accordance with Article V hereof of
     another Person to the Company and the assumption by any such successor of
     the covenants of the Company herein and in the Securities;

          (e)  to add any Subsidiary of the Company as a Subsidiary Guarantor
     pursuant to the terms of Section 4.15 and Article XI;

          (f)  to evidence and provide for the acceptance of appointment
     hereunder by a separate or successor Trustee with respect to the
     Securities; or

          (g)  to make any other change that does not adversely affect the
     rights of any Holder;

provided, however, that in making such change, the Trustee may rely upon an
Opinion of Counsel stating that such change does not adversely affect the rights
of any Holder.

          SECTION 9.2  With Consent of Holders.

          Subject to Section 6.7 and the provisions of this Section 9.2, the
Company, when authorized by resolution of its Board of Directors (copies of
which shall be delivered to the Trustee) and the Trustee may amend or supplement
this Indenture, the Securities or any Subsidiary Guarantee with the written
consent of the Holders of at least a majority in 
<PAGE>
 
                                     -87-

principal amount of the Securities then outstanding. Subject to Section 6.7 and
the provisions of this Section 9.2, the Holders of, in the aggregate, at least a
majority in principal amount of the then outstanding Securities affected may
waive compliance by the Company and any Subsidiary Guarantor with any provision
of this Indenture, the Securities or any Subsidiary Guarantee without notice to
any other Securityholder. However, without the consent of each Securityholder
affected, an amendment, supplement or waiver, including a waiver pursuant to
Section 6.4, may not:

          (a)  reduce the aggregate principal amount of Securities the Holders
     of which must consent to an amendment, supplement or waiver of any
     provision of or with respect to this Indenture, the Securities or any
     Subsidiary Guarantee; or

          (b)  reduce the rate of, change the method of calculation of, or
     extend the time for, payment of interest, including default interest, on
     any Security; or

          (c)  reduce the principal of or premium on or change the Stated
     Maturity of any Security or alter the repurchase provisions with respect
     thereto; or

          (d)  make the principal of, or interest on, any Security payable in
     money other than as provided herein, or

          (e)  make any change in provisions relating to waivers of defaults,
     the ability of Holders to enforce their rights under this Indenture or in
     the matters discussed in clauses (a) through (h); or

          (f)  waive a default in the payment of the principal of, interest on,
     or repurchase payment required hereunder with respect to, any Security,
     including, without limitation, a default to make a payment when required
     upon a Change of Control; or

          (g)  adversely affect the ranking of the Securities or any Subsidiary
     Guarantee or release any Subsidiary Guarantor from any of its obligations
     under its Subsidiary Guarantee in this Indenture other than in compliance
     with Section 11.4 of Exhibit B hereto;

          (h)  after the Company's obligation to purchase Securities arises
     thereunder, amend, modify or change the obligation of the Company to make
     and consummate a Change of Control Offer in the event of a Change of
     Control or waive any default in the performance thereof or modify any of
     the provisions or definitions with respect to such offers.
<PAGE>
 
                                     -88-

          It shall not be necessary for the consent of the Holders under this
Section 9.2 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 9.2
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.
Notwithstanding the foregoing, no amendment shall modify any provision of this
Indenture so as to affect adversely the rights of any holder of Senior
Indebtedness of the Company or Guarantor Senior Indebtedness to the benefits of
the subordination provisions under this Indenture without the consent of such
holder.

          SECTION 9.3  Compliance with Trust Indenture Act.

          Every amendment to or supplement of this Indenture or the Securities
shall be set forth in a supplemental indenture that complies with the TIA as
then in effect.

          SECTION 9.4  Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder is a continuing consent by the Holder and every subsequent
Holder of that Security or portion of that Security that evidences the same debt
as the consenting Holder's Security, even if notation of the consent is not made
on any Security.  However, any such Holder or subsequent Holder may revoke the
consent as to his Security or portion of a Security.  Such revocation shall be
effective only if the Trustee receives the notice of revocation before the date
the amendment, supplement or waiver becomes effective.  Notwithstanding the
above, nothing in this paragraph shall impair the right of any Securityholder
under (S) 316(b) of the TIA.

          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 record date shall be at least 10 days prior to the
first solicitation of such consent.  If a record date is fixed, then
notwithstanding the second and third sentences 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 consent to
such amendment, supplement or waiver or to revoke any consent previously given,
whether or not such Persons continue to be Holders after such record date.  Such
consent shall be effective only for actions taken within 90 days after such
record date.
<PAGE>
 
                                     -89-

          After an amendment, supplement or waiver becomes effective, it shall
bind every Securityholder unless it makes a change described in any of clauses
(a) through (h) of Section 9.2.  In that case the amendment, supplement or
waiver shall bind each Holder of a Security who has consented to it.

          SECTION 9.5  Notation on or Exchange of Securities.

          If an amendment, supplement or waiver changes the terms of a Security,
the Trustee shall (in accordance with the specific written direction of the
Company) request the Holder of the Security to deliver it to the Trustee.  The
Trustee shall (in accordance with the specific direction of the Company) place
an appropriate notation on the Security 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 Security shall issue and the Trustee shall
authenticate a new Security that reflects the changed terms.  Failure to make
the appropriate notation or issue a new Security shall not affect the validity
and effect of such amendment, supplement or waiver.

          SECTION 9.6  Trustee To Sign Amendments, Etc.

          The Trustee shall sign any amendment, supplement or waiver authorized
pursuant to this Article IX if the amendment, supplement or waiver does not
adversely affect the rights, duties or immunities of the Trustee.  If it does,
the Trustee may, but need not, sign it.  In signing any amendment, supplement or
waiver, 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 Officers' Certificate and an Opinion of Counsel stating that
the execution of any amendment, supplement or waiver authorized pursuant to this
Article IX is authorized or permitted by this Indenture and that it constitutes
the legal, valid and binding obligation of the Company and, if applicable, the
Subsidiary Guarantors, subject to the customary exceptions.

                                   ARTICLE X

                            7% SENIOR NOTE DUE 2003

          1.  Interest.  NAVISTAR INTERNATIONAL CORPORATION, a Delaware
corporation (the "Company," which definition shall include any successor thereto
in accordance with the Indenture (as defined below)), promises to pay, until the
principal hereof is paid or made available for payment, interest on the
principal amount set forth on the reverse side hereof at a rate of 7% per annum.
                                                                      --- -----
Interest on the Securities will accrue from and including the most recent date
to which interest has been paid or, if no interest has been paid, from and
including February 4, 1998 through but excluding the date on which interest is
paid.  Interest shall be payable in arrears on February 1, August 1 and at the
stated maturity (each an "Interest Payment Date"), commencing August 1, 1998.
Interest will be computed on the basis of a 360-day year of twelve full 30-day
months and, for periods of less than one month, the actual number of days
elapsed.  Interest on overdue principal and (to the extent permitted by law) on
overdue installments of interest will accrue at a rate equal to 7% per annum.
                                                                   --- ----- 

          2.  Method of Payment.  The Company will pay interest on the
Securities (except defaulted interest) to the Persons who are registered Holders
of Securities at the close of business on the January 15 or July 15 next
preceding the relevant Interest Payment Date.  Holders must surrender Securities
to the Paying Agent to collect principal payments.  The Company will pay
principal, premium, if any, and interest in money of the United States that at
the time of payment is legal tender for payment of public and private debts.  At
the Company's option, interest may be paid by check mailed to the registered
address of the Holder of this Security.

          3.  Paying Agent and Registrar.  Initially, HARRIS TRUST AND SAVINGS
BANK (the "Trustee") will act as Paying Agent and Registrar.  The Company may
change any Paying Agent, Registrar or co-Registrar without notice. Neither the
Company nor any of its Subsidiaries may act as Paying Agent, Registrar or co-
Registrar.

          4.  Indenture.  The Company issued the Securities under an Indenture
dated as of February 4, 1998 (the "Indenture") between the Company and the
Trustee.  This Security is one of an issue of Securities of the Company issued
under the Indenture.  The terms of the Securities 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) as amended from time to
time.  The Securities are subject to all such terms, and Securityholders are
referred to the Indenture and such Act for a statement of them.  Capitalized
terms used herein and not otherwise defined have the meanings set forth in the
Indenture.  The 

                                      A-2
<PAGE>
 
Securities are general unsecured obligations of the Company limited in aggregate
principal amount to $100,000,000. The Indenture limits, among other things, the
incurrence of certain Indebtedness by the Company and its Restricted
Subsidiaries; transactions by the Company and its Restricted Subsidiaries with
certain Affiliates; the granting of Liens by the Company or any of its
Restricted Subsidiaries; certain guarantees issued by Restricted Subsidiaries of
the Company and the ability of the Company and the Subsidiary Guarantors to
merge with or into another entity. The limitations are subject to a number of
important qualifications and exceptions. The Company must report to the Trustee
annually whether it is in compliance with the limitations contained in the
Indenture.

          5.  Offers to Purchase.  Sections 4.11 and 4.19 of the Indenture
provide upon the occurrence of a Change of Control and after certain Asset
Disposition, and subject to further limitations contained therein, the Company
shall make an offer to purchase certain amount of the Securities in accordance
with the procedures set forth in the Indenture.

          6.  Denominations, Transfer, Exchange.  The Securities are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000.  A Holder may transfer or exchange Securities in accordance
with the Indenture.  The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay to it any
taxes and fees required by law or permitted by the Indenture.  The Registrar
need not transfer or exchange any Security or portion of a Security selected for
redemption, or transfer or exchange any Securities for a period of 15 days
before a selection of Securities to be redeemed.

          7.  Persons Deemed Owners.  The registered holder of a Security may be
treated as the owner of it for all purposes.

          8.  Unclaimed Money.  If money for the payment of principal or
interest remains unclaimed for two years, the Trustee or Paying Agent will pay
the money back to the Company at its request.  After that, Holders entitled to
the money must look to the Company for payment as general creditors unless an
"abandoned property" law designates another Person.

          9.  Amendment, Supplement, Waiver.  The Company and the Trustee may,
without the consent of the holders of any outstanding Securities, amend, waive
or supplement the Indenture, the Securities or Subsidiary Guarantee for certain
specified purposes, including, among other things, curing ambiguities, defects
or inconsistencies, maintaining the qualification of the Indenture under the
Trust Indenture Act of 1939 or making any other change that does not adversely
affect the rights of any Holder.  Other amendments and modifications of the
Indenture, the Securities or any Subsidiary Guarantee may be made by the Company
and the Trustee with the consent of the Holders of not less than a majority of
the aggregate principal amount of the outstanding Securities, subject to certain
exceptions requiring the consent of the Holders of the particular Securities to
be affected.

          10.  Successor Corporation.  When a successor corporation assumes all
the obligations of its predecessor under the Securities and the Indenture and
the transaction complies with the terms of Article V of the Indenture, the
predecessor corporation, subject to certain exceptions, will be released from
those obligations.

          11.  Defaults and Remedies.  Events of Default are set forth in the
Indenture. Subject to certain limitations in the Indenture, if an Event of
Default (other than an Event of Default specified in Section 6.1(a)(vii) or
(viii) of the Indenture with respect to the Company) occurs and is continuing,
then the holders of not less than 25% in aggregate principal amount of the
outstanding Securities may, or the Trustee may, declare the principal of,
premium, if any, plus accrued interest, if any, to be due and payable
immediately.  If an Event of Default specified in Section 6.1(a)(vii) or (viii)
of the Indenture with respect to the Company occurs and is continuing, the
principal of, premium, if any, and accrued interest on all of the Securities
shall ipso facto become and be immediately due and payable without any
      ---- -----                                                      
declaration or other act on the part of the Trustee or any Holder.
Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture.  The Trustee may require indemnity reasonably
satisfactory to it before it enforces the Indenture or the Securities.  Subject
to certain limitations, Holders of a majority in principal amount of the then
outstanding Securities may direct the Trustee in its exercise of any trust or
power.  The Trustee may withhold from Securityholders notice of any continuing
default (except a default in payment of principal or interest or a failure to
comply with Article V of the Indenture) if it determines that withholding notice
is in their interests. The Company must furnish an annual compliance certificate
to the Trustee.

          12.  Guarantees.  This Security may after the date hereof be entitled
to certain Subsidiary Guarantees made for the benefit of the Holders.  Reference
is hereby made to Section 4.15 of the Indenture and to Exhibit B to the
Indenture for the terms of any Subsidiary Guarantee (including any terms of
subordination of such Subsidiary Guarantee that may apply).

          13.  Trustee Dealings with Company.  The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not Trustee.

          14.  No Recourse Against Others.  A Trustee, director, officer,
employee, stockholder or beneficiary, as such, of the Company or any Subsidiary
Guarantor shall not have any liability for any obligations of the Company or any
Subsidiary Guarantor under the Securities, the Indenture or any Subsidiary
Guarantee or for any claim based on, in respect of or by reason of, such
obligations or their creation.  Each Securityholder by accepting a Security
waives and releases all such liability.  The waiver and release are part of the
consideration for the issue of the Securities.

          15.  Defeasance.  The Indenture contains provisions (which provisions
apply to this Security) for defeasance at any time of (a) the entire
indebtedness of the Company and any Subsidiary Guarantor or this Security and
(b) certain restrictive covenants and related Defaults and Events of Default, in
each case upon compliance by the Company with certain conditions set forth
therein.

          16.  Authentication.  This Security shall not be valid until the
Trustee signs the certificate of authentication on the other side of this
Security.

          17.  Abbreviations.  Customary abbreviations may be used in the name
of a Securityholder or an assignee, such as: TEN COM (= tenants in common),

survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (=
Uniform Gifts to Minors Act).

          18.  GOVERNING LAW.  THE INDENTURE, THIS SECURITY AND EACH SUBSIDIARY
GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE

                                   ARTICLE XI

                            GUARANTEE OF SECURITIES

          SECTION 11.1  Subsidiary Guarantee.

          Subject to the provisions of this Article XI, each Subsidiary
Guarantor hereby jointly and severally unconditionally guarantees to each Holder
of a Security authenticated and delivered by the Trustee and to the Trustee and
its successors and assigns, irrespective of the validity and enforceability of
this Indenture, the Securities or the obligations of the Company or any other
Subsidiary Guarantors to the Holders or the Trustee hereunder or thereunder,
that:  (a) the principal of, premium, if any, and interest on the Securities
will be duly and punctually paid in full when due, whether at maturity, by
acceleration or otherwise, and interest on the overdue principal and (to the
extent permitted by law) interest, if any, on the Securities and all other
obligations of the Company or the Subsidiary Guarantors to the Holders or the
Trustee hereunder or thereunder (including fees or expenses) and all other
obligations with respect to the Securities and this Indenture will be promptly
paid in full or performed, all in accordance with the terms hereof and thereof;
and (b) in case of any extension of time of payment or renewal of any
Securities, the same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at Stated
Maturity, by acceleration or otherwise.  Failing payment when due of any amount
so guaranteed, or failing performance of any other obligation of the Company to
the Holders, for whatever reason, each Subsidiary Guarantor will be obligated to
pay, or to perform or cause the performance of, the same immediately.  An Event
of Default under this Indenture or the Securities shall constitute an event of
default under this Subsidiary Guarantee, and shall entitle the Holders of
Securities to accelerate the obligations of the Subsidiary Guarantors hereunder
in the same manner and to the same extent as the obligations of the Company.

          Each of the Subsidiary Guarantors hereby agrees that its obligations
hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Securities or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any holder of the Securities with
respect to any provisions hereof or thereof, any release of any other Subsidiary
Guarantor, the recovery of any judgment against the Company, any action to
enforce the same, whether or not a Subsidiary Guarantee is affixed to any
particular Security, or any other circumstance which might otherwise constitute
a legal or equitable discharge or defense of a guarantor.  Each of the
Subsidiary Guarantors hereby waives the benefit of 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 pro-

                                      B-1
<PAGE>
 
ceeding first against the Company, protest, notice and all demands whatsoever
and covenants that its Subsidiary Guarantee will not be discharged except by
complete performance of the obligations contained in the Securities, this
Indenture and this Subsidiary Guarantee. If any Holder or the Trustee is
required by any court or otherwise to return to the Company or to any Subsidiary
Guarantor, or any custodian, trustee, liquidator or other similar official
acting in relation to the Company or such Subsidiary Guarantor, any amount paid
by the Company or such Subsidiary Guarantor to the Trustee or such Holder, this
Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated
in full force and effect. Each Subsidiary Guarantor further agrees that, as
between it, on the one hand, and the Holders of Securities and the Trustee, on
the other hand, (a) subject to this Article XI, the maturity of the obligations
guaranteed hereby may be accelerated as provided in Article VI hereof for the
purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (b) in the event of any acceleration of such obligations
as provided in Article VI hereof, such obligations (whether or not due and
payable) shall forthwith become due and payable by the Subsidiary Guarantors for
the purpose of this Subsidiary Guarantee.

          This Subsidiary Guarantee shall remain in full force and effect and
continue to be effective should any petition be filed by or against the Company
for liquidation or reorganization, should the Company become insolvent or make
an assignment for the benefit of creditors or should a receiver or trustee be
appointed for all or any significant part of the Company's assets, and shall, to
the fullest extent permitted by law, continue to be effective or be reinstated,
as the case may be, if at any time payment and performance of the Securities
are, pursuant to applicable law, rescinded or reduced in amount, or must
otherwise be restored or returned by any obligee on the Securities, whether as a
"voidable preference," "fraudulent transfer" or otherwise, all as though such
payment or performance had not been made.  In the event that any payment, or any
part thereof, is rescinded, reduced, restored or returned, the Securities shall,
to the fullest extent permitted by law, be reinstated and deemed reduced only by
such amount paid and not so rescinded, reduced, restored or returned.

          No stockholder, officer, director, employer or incorporator, past,
present or future, or any Subsidiary Guarantor, as such, shall have any personal
liability under this Subsidiary Guarantee by reason of his, her or its status as
such stockholder, officer, director, employer or incorporator.

          The Subsidiary Guarantors shall have the right to seek contribution
from any non-paying Subsidiary Guarantor so long as the exercise of such right
does not impair the rights of the Holders under this Subsidiary Guarantee.

          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 each Subsidiary Guarantor pursuant to its Subsidiary Guarantee not constitute
a fraudulent transfer 

                                      B-2
<PAGE>
 
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 each
Subsidiary Guarantor hereby irrevocably agrees that the obligations of each
Subsidiary Guarantor under the Subsidiary Guarantees shall be limited to the
maximum amount as will, after giving effect to all other contingent and fixed
liabilities of each Subsidiary Guarantor (including, but not limited to, the
Guarantor Senior Indebtedness of each Subsidiary Guarantor) result in the
obligations of each Subsidiary Guarantor under the Subsidiary Guarantees not
constituting such fraudulent transfer or conveyance.

          SECTION 11.2  Execution and Delivery of Subsidiary Guarantee.

          To further evidence the Subsidiary Guarantee set forth in Section
11.1, each Subsidiary Guarantor hereby agrees that a notation of such Subsidiary
Guarantee, substantially in the form included in Exhibit C hereto, shall be
endorsed on each Security authenticated and delivered by the Trustee after such
Subsidiary Guarantee is executed and executed by either manual or facsimile
signature of an Officer of each Subsidiary Guarantor.  The validity and
enforceability of any Subsidiary Guarantee shall not be affected by the fact
that it is not affixed to any particular Security.

          Each of the Subsidiary Guarantors hereby agrees that its Subsidiary
Guarantee set forth in Section 11.1 shall remain in full force and effect
notwithstanding any failure to endorse on each Security a notation of such
Subsidiary Guarantee.

          If an Officer of a Subsidiary Guarantor whose signature is on this
Indenture or a Security no longer holds that office at the time the Trustee
authenticates such Security or at any time thereafter, such Subsidiary
Guarantor's Subsidiary Guarantee of such Security shall be valid nevertheless.

          The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Subsidiary Guarantee set
forth in this Indenture on behalf of the Subsidiary Guarantor.

          SECTION 11.3  Additional Subsidiary Guarantors.

          Any person may become a Subsidiary Guarantor by executing and
delivering to the Trustee (a) a supplemental indenture in form and substance
satisfactory to the Trustee, which subjects such person to the provisions of
this Indenture as a Subsidiary Guarantor, and (b) an Opinion of Counsel to the
effect that such supplemental indenture has been duly authorized and executed by
such person and constitutes the legal, valid, binding and enforceable obligation
of such person (subject to such customary exceptions concerning fraudulent
conveyance laws, creditors' rights and equitable principles as may be acceptable
to the Trustee in its discretion).

          SECTION 11.4  Release of a Subsidiary Guarantor.

          (a)  In the event that each other holder of Indebtedness of the
Company or of any of the Company's Subsidiaries of which a Subsidiary Guarantor
has guaranteed the payment thereof unconditionally releases a Subsidiary
Guarantor of all of its obligations under such guarantee pursuant to a written
agreement in form and substance satisfactory to the Trustee (other than a
release resulting from payment under such guarantee) such Subsidiary Guarantor
shall be automatically and unconditionally released from all obligations under
its Subsidiary Guarantee, provided that a release of a Subsidiary Guarantor may
only be obtained under the circumstances described in this sentence if an
Officers' Certificate to that effect has been delivered to the Trustee.

          (b)  In addition, except in the case where the prohibition on transfer
in Section 5.1 is applicable, upon the sale or disposition of all (but not less
than all) of the Capital Stock of a Subsidiary Guarantor by the Company or a
Subsidiary of the Company, or upon the consolidation or merger of a Subsidiary
Guarantor with or into any Person (in each case, other than to the Company or an
Affiliate of the Company), such Subsidiary Guarantor shall be deemed
automatically and unconditionally released and discharged from all obligations
under this Article XI without any further action required on the part of the
Trustee or any Holder, provided that each such Subsidiary Guarantor is sold or
disposed of in accordance with Article V.

          (c)  The Trustee shall deliver an appropriate instrument evidencing
the release of a Subsidiary Guarantor upon receipt of a request of the Company
accompanied by an Officers' Certificate certifying as to the compliance with
this Section 11.4.  Any Subsidiary Guarantor not so released or the entity
surviving such Subsidiary Guarantor, as applicable, will remain or be liable
under its Subsidiary Guarantee as provided in this Article XI.

          The Trustee shall execute any documents reasonably requested by the
Company or a Subsidiary Guarantor in order to evidence the release of such
Subsidiary Guarantor from its obligations under its Subsidiary Guarantee
endorsed on the Securities and under this Article XI.

          Except as set forth in Articles IV and V and this Section 11.4,
nothing contained in this Indenture or in any of the Securities 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
property of a Subsidiary Guarantor as an entirety or substantially as an
entirety to the Company or another Subsidiary Guarantor.

          SECTION 11.5  Waiver of Subrogation.

          Each Guarantor hereby irrevocably waives any claim or other rights
which it may now or hereafter acquire against the Company or any of its
Subsidiaries that arise from 

                                      B-4
<PAGE>
 
the existence, payment, performance or enforcement of such Subsidiary
Guarantor's obligations under this Subsidiary 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 Securities against the Company or any of its
Subsidiaries, 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 or any of its Subsidiaries, 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 Securities 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 Securities, and shall
forthwith be paid to the Trustee for the benefit of such Holders to be credited
and applied upon the Securities, 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
11.5 is knowingly made in contemplation of such benefits.

          SECTION 11.6  Agreement to Subordinate.

          Each Subsidiary Guarantor covenants and agrees, and each Holder of
Securities, by his acceptance thereof, likewise covenants and agrees, that the
indebtedness represented by such Subsidiary Guarantor's Subsidiary Guarantee and
the payment of the principal of and interest on each and all of the Securities
pursuant to such Subsidiary Guarantor's Subsidiary Guarantee is hereby expressly
subordinated, to the extent and in the manner hereinafter set forth, in right of
payment to the prior payment in full of Guarantor Senior Indebtedness.

          Anything in the Subsidiary Guarantee, the Securities or in this
Indenture to the contrary notwithstanding, the indebtedness evidenced by such
Subsidiary Guarantor's Subsidiary Guarantee shall be subordinate and junior in
right of payment, in all respects, to all Guarantor Senior Indebtedness of such
Subsidiary Guarantor, whether outstanding at the Issue Date or incurred after
the Issue Date.  Without limiting the effect of the foregoing, "subordinate" and
"junior" as used herein shall include within their meanings the following:

             (i) in the event of any insolvency or bankruptcy proceedings, and
     any receivership, liquidation, reorganization or other similar proceedings
     in connection therewith, relative to the Subsidiary Guarantor or its
     creditors or its property, and in the event of any proceedings for
     voluntary liquidation, dissolution or other winding up of the Subsidiary
     Guarantor, whether or not involving insolvency or bankruptcy proceedings,
     then (A) all Guarantor Senior Indebtedness of such Subsidiary Guarantor
     shall first be paid in full, or such payment be provided for, before any
     payment on account of principal or interest is made upon the Indebtedness
     evidenced by 

                                      B-5
<PAGE>
 
     the Subsidiary Guarantee of such Subsidiary Guarantor, and (B) in any such
     proceedings any payment or distribution of any kind or character (including
     without limitation any distribution realized from or attributable to any
     security interest of the Holders of the Securities in property or assets of
     such Subsidiary Guarantor), whether in cash or property or securities which
     may be payable or deliverable in respect of the Subsidiary Guarantee of
     such Subsidiary Guarantor, shall be paid or delivered directly to the
     holders of such Guarantor Senior Indebtedness of such Subsidiary Guarantor
     (or the representative or representatives of such holders or the trustee or
     trustees under any indenture under which any instruments evidencing any of
     such Guarantor Senior Indebtedness of such Subsidiary Guarantor shall have
     been issued) for application in payment thereof, unless and until such
     Guarantor Senior Indebtedness of such Subsidiary Guarantor shall have been
     paid in full or such payment shall have been provided for; provided that
     (1) in the event that payment or delivery of such cash, property or
     securities to the Holders of the Securities is authorized by an order or
     decree giving effect, and stating in such order or decree that effect is
     given, to the subordination of the Subsidiary Guarantee of such Subsidiary
     Guarantor to Guarantor Senior Indebtedness of such Subsidiary Guarantor,
     and made by a court of competent jurisdiction in a reorganization
     proceeding under any applicable law, no payment or delivery of such cash,
     property or securities payable or deliverable with respect to the
     Securities need be made to the holders of Guarantor Senior Indebtedness of
     such Subsidiary Guarantor, (2) no such delivery need be made of securities
     which are issued pursuant to voluntary reorganization, dissolution, or
     liquidation proceedings by such Subsidiary Guarantor or by such Subsidiary
     Guarantor as reorganized, if such securities are subordinate and junior to
     the payment of all Guarantor Senior Indebtedness of such Subsidiary
     Guarantor then outstanding to the same extent as the Subsidiary Guarantee
     of such Subsidiary Guarantor and (3) if, pursuant to the foregoing, a
     payment or delivery of cash, property or securities is to be made to the
     holders of Guarantor Senior Indebtedness of such Subsidiary Guarantor (or
     their representative or representatives or the trustee or trustees under
     any indenture under which any instruments evidencing any such Guarantor
     Senior Indebtedness of such Subsidiary Guarantor shall have been issued)
     from a distribution realized from or attributable to any security interest
     of the Holders of the Securities in property or assets of such Subsidiary
     Guarantor, such payment or delivery shall be made (x) first, to the holders
     of any Guarantor Senior Indebtedness of such Subsidiary Guarantor (or their
     representative or representatives) secured equally and ratably with the
     Holders of the Securities with respect to such property or assets or to the
     trustee or trustees under any indenture under which any instruments
     evidencing any of such Guarantor Senior Indebtedness of such Subsidiary
     Guarantor shall have been issued, ratably according to the aggregate
     amounts remaining unpaid on account of such Guarantor Senior Indebtedness
     of such Subsidiary Guarantor held or represented by each, until such
     Guarantor Senior Indebtedness of such Subsidiary Guarantor shall have been
     paid in full or such payment

     shall have been provided for and (y) then, to the extent such payment or
     delivery shall not be required to pay the Guarantor Senior Indebtedness of
     such Subsidiary Guarantor referred to in the foregoing clause (x), to the
     other holders of Guarantor Senior Indebtedness of such Subsidiary Guarantor
     (or their representative or representatives or the trustee or trustees
     under any indenture under which any instruments evidencing any of such
     Guarantor Senior Indebtedness of such Subsidiary Guarantor shall have been
     issued), ratably according to the aggregate amounts remaining unpaid on
     account of such Guarantor Senior Indebtedness of such Subsidiary Guarantor
     held or represented by each, until such Guarantor Senior Indebtedness of

regardless of any knowledge thereof any such holder may have or be otherwise
charged with.

been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context shall require
otherwise) be construed as extending to and including such Paying Agent within

such specified Person or (b) such acquisition by the specified Person.

          "Additional Interest" shall have the meaning set forth in the

          If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless.

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

Issue Date in the aggregate principal amount of $250,000,000, (ii) Private
Exchange Securities from time to time only in exchange for a like principal
amount of Initial Securities and (iii) Unrestricted Securities from time to time
only in exchange for a like principal amount of Initial Securities, in each case
upon a written order signed by an Officer of the Company.  The order shall be

Securities to be authenticated and the date on which the original issue of
Securities is to be authenticated.  The order shall also provide instructions
concerning registration, legends, if any, pursuant to Section 2.6(f), amounts

have one or more additional paying agents. The term "Paying Agent" includes any
additional paying agent.

          The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture.  The agreement shall implement the
provisions of this Indenture that relate to such Agent and shall, if required,
incorporate the provisions of the TIA.  The Company shall notify the Trustee in
writing of the name and address of any such Agent.  If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation in accordance with the provisions of
Section 7.7.

Agent.  The Company shall give written notice to the Trustee in the event that

Securities (whether such money has been paid to it by the Company or any other
obligor on the Securities), and the Company and the Paying Agent shall each
notify the Trustee of any default by the Company (or any other obligor on the
Securities) in making any such payment.  The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee and account for any
funds 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 pay all money held by it to the Trustee and to account for any funds
disbursed.  Upon making such payment the Paying Agent shall have no further
liability for the money delivered to the Trustee.

          SECTION 2.5  Securityholder 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
Securityholders.  If the Trustee is not the Registrar, the Company shall furnish
to the Trustee at least five Business Days before each Interest Payment Date and
at such other times as the Trustee may request in writing a list in such form
and as of such date as the Trustee may reasonably require of the names and
addresses of Securityholders.

          SECTION 2.6  Transfer and Exchange.

          (a) Transfer and Exchange of Global Securities.  Transfer of the
Global Securities shall be by delivery.  Global Securities may not be
transferred as or exchanged for Physical Securities except (i) if DTC notifies
the Company that it is unwilling or unable to continue to act as depositary with
respect to the Global Securities or ceases to be a clearing agency registered
under the Exchange Act and, in either case, a successor depositary registered as
a clearing agency under the Exchange Act is not appointed by the Company within
120 days, (ii) at any time if the Company in its sole discretion determines that
the Global Securities (in whole but not in part) should be exchanged for
Physical Securities or (iii) if the owner of an interest in the Global
Securities requests such Physical Securities, following an Event of Default
under this Indenture, in a writing delivered through DTC to the Trustee.

          Upon the occurrence of any of the events specified in the previous
paragraph, Physical Securities shall be issued in such names as DTC shall
instruct the Trustee and the Trustee shall cause the aggregate principal amount
of the applicable Global Security to be reduced accordingly and direct DTC to
make a corresponding reduction in its book-entry system.  The Company shall
execute and the Trustee shall authenticate and deliver to the Person designated
in such instructions a Physical Security in the appropriate principal amount.
The Trustee shall deliver such Physical Securities to the Persons in whose names
such Securities are so registered.  Physical Securities issued in exchange for
an Initial Global Security pursuant to this Section 2.6 (a) shall bear the
Securities Act Legend and shall be subject to all restrictions on transfer
contained therein.  Global Securities may also be exchanged or replaced, in
whole or in part, as provided in Sections 2.7 and 2.8.  Every Security
authenticated and delivered in exchange for, or in lieu of, a Global Security or
any portion thereof, pursuant to Section 2.7 or 2.8, shall be authenticated and
delivered in the form of, and shall be, a Global Security.  A Global Security
may not be exchanged for another Security other than as provided in this Section
2.6(a).

          (b) Transfer and Exchange of Interests in Global Securities.  The
transfer and exchange of interests in Global Securities shall be effected
through DTC, in accordance with this Indenture and the procedures of DTC
therefor.  Interests in Initial Global Securities shall be subject to
restrictions on transfer comparable to those set forth herein to the extent
required by the Securities Act.  The Trustee shall have no obligation to
ascertain DTC's compliance with any such restrictions on transfer.  Transfers of
interests in Global Securities shall also require compliance with subparagraph
(i) below, as well as one or more of the other following subparagraphs as
applicable:

             (i)   All Transfers and Exchanges of Interests in Global
     Securities. In connection with all transfers and exchanges of interests in

                                      -33-

     than transfers of interests in a Global Security to Persons who take
     delivery thereof in the form of an interest in the same Global Security),
     the transferor of such interest must deliver to the Registrar (1)
     instructions given in accordance with the Applicable Procedures from a
     Participant or an indirect Participant directing DTC to credit or cause to
     be credited an interest in the specified Global Security in an amount equal
     to the interest to be transferred or exchanged, (2) a written order given
     in accordance with the Applicable Procedures containing information
     regarding the Participant account to be credited with such increase and (3)
     instructions given by the Holder of the Global Security to effect the
     transfer referred to in (1) and (2) above.

             (ii)  Transfer of Interests in the Same Initial Global Security.

     take delivery thereof in the form of an interest in the same Initial Global
     Security in accordance with the transfer restrictions set forth in Section
     2.6(f) hereof.  It shall be the sole responsibility of the selling
     beneficial owner to deliver these transfer documents, if any are required,
     to the Company and the Trustee shall have no responsibility or duty to
     collect the transfer documentation set forth in Section 2.6(f).

             (iii) Transfer of Interests to Another Initial Global Security.
     Interests in any Initial Global Security may be transferred to Persons who
     take delivery thereof in the form of an interest in another Initial Global
     Security if the Registrar receives the following:

                   (A) if the transferee will take delivery in the form of an
             interest in the 144A Global Security, then the transferor must
             deliver a certificate in the form of Exhibit D hereto, including
             the certifications in item 1 thereof; or

                   (B) if the transferee will take delivery in the form of an
             interest in the Regulation S Global Security, then the transferor
             must deliver a certificate in the form of Exhibit D hereto,
             including the certifications in item 2 thereof.

             (iv)  Transfer and Exchange of Interests in Initial Global Security
     for Interests in an Unrestricted Global Security.  Interests in any Initial
     Global Security may be exchanged by the holder thereof for an interest in
     the Unrestricted Global Security or transferred to a Person who takes
     delivery thereof in the form of an interest in the Unrestricted Global
     Security if:

                   (A) such exchange or transfer is effected pursuant to the
          Exchange Registration Statement in accordance with the Registration
          Rights Agreement

                   the Unrestricted Global Security, a certificate from such
                   Holder in the form of Exhibit E hereto, including the
                   certifications in item 1(a) thereof;

                       (2) if the holder of such an interest in an Initial
                   Global Security proposes to transfer it to a Person who shall
                   take delivery thereof in the form of an interest in an
                   Unrestricted Global Security, a certificate in the form of
                   Exhibit D hereto, including the certification in item 4
                   thereof; and

                       (3) in each such case set forth in this paragraph (C), an
                   Opinion of Counsel in form reasonably acceptable to the
                   Company and the Trustee, to the effect that such exchange or
                   transfer is in compliance with the Securities Act and, that
                   the restrictions on transfer contained herein and in Section
                   2.6(f) hereof are not required in order to maintain
                   compliance with the Securities Act.

     If any such transfer is effected pursuant to paragraph (B) above at a time
     when an Unrestricted Global Security has not yet been issued, the Company
     shall issue and, upon receipt of an authentication order in accordance with
     Section 2.2, the Trustee shall authenticate one or more Unrestricted Global
     Securities in an aggregate principal amount equal to the principal amount
     of interests in the Initial Global Security transferred pursuant to
     paragraph (B) above, provided the Company has made appropriate arrangements
     with DTC prior to delivery of such an authentication order to the Trustee.

             (v)   Notation by the Trustee of Transfer of Interests Among Global
     Securities. Upon satisfaction of the requirements for transfer of interests
     in Global Secu

     rities pursuant to clauses (iii) or (iv) above, the Trustee shall reduce or
     cause to be reduced the aggregate principal amount of the relevant Global
     Security from which the interests are being transferred, and increase or
     cause to be increased the aggregate principal amount of the Global Security
     to which the interests are being transferred, in each case, by the
     principal amount so transferred and shall direct DTC to make corresponding
     adjustments in its book-entry system. No transfer of interests of a Global
     Security shall be effected until, and any transferee pursuant thereto shall
     succeed to the rights of a holder of such interests only when, the
     Registrar has made appropriate adjustments to the applicable Global
     Security in accordance with this paragraph.

          (c)      Transfer or Exchange of Physical Securities for Interests in
a Global Security.

             (i)   If any Holder of Physical Securities required to contain the
     Securities Act Legend proposes to exchange such Securities for an interest

            Exhibit E hereto, including the certifications in item 2 thereof;

            certificate to the effect set forth in Exhibit D hereto, including
            the certifications in item 1 thereof; or

             (ii)  A Holder of Physical Securities required to contain the
     Securities Act Legend may exchange such Securities for an interest in the
     Unrestricted Global Security or transfer such Restricted Physical
     Securities to a Person who takes delivery thereof in the form of an
     interest in the Unrestricted Global Security only:

                   (A) if such exchange or transfer is effected pursuant to the
             Exchange Registration Statement in accordance with the Registration
             Rights Agreement and the Company delivers an Officers' Certificate
             to the Trustee stating that such Exchange Registration Statement
             has become effective and directing the Trustee to effect the

                   thereof in the form of an interest in the Unrestricted Global
                   Security, a certificate in the form of Exhibit D hereto,
                   including the certifications in item 4 thereof; and

                       (3) in each such case set forth in this paragraph (C), an
                   Opinion of Counsel in form reasonably acceptable to the
                   Company, to the effect that such exchange or transfer is in
                   compliance with the Securities Act and that the restrictions
                   on transfer contained herein and in Section 2.6(f) hereof are
                   not required in order to maintain compliance with the
                   Securities Act.

     when an Unrestricted Global Security has not yet been issued, the Company
     shall issue and, 
<PAGE>
 
                                      -37-

     upon receipt of an authentication order in accordance with Section 2.2, the
     Trustee shall authenticate (i) one or more Unrestricted Global Securities
     in an aggregate principal amount equal to the principal amount of Physical
     Securities transferred pursuant to paragraph (B) above.

          (d)      Transfer and Exchange of Physical Securities.

             (i)   Transfer of a Physical Security to Another Physical Security.
     Following the occurrence of one or more of the events specified in Section
     2.6(a), a Physical Security may be transferred to Persons who take delivery
     thereof in the form of another Physical Security if the Registrar receives
     the following:

                   (A) if the transfer is being effected pursuant to and in
             accordance with Rule 144A, then the transferor must deliver a
             certificate in the form of Exhibit D hereto, including the
             certifications in item 3(a) thereof; or

                   (B) if the transfer is being effected pursuant to and in
             accordance with Regulation S, then the transferor must deliver a
             certificate in the form of Exhibit D hereto, including the

             (ii)  Transfer and Exchange of Restricted Physical Security for
     Physical Security Which Does Not Bear the Securities Act Legend. Following
     the occurrence of one or more of the events specified in Section 2.6(a) and
     the receipt by the Trustee of an Officers' Certificate stating that such
     events have occurred, a Restricted Physical Security may be exchanged by
     the Holder thereof for a Physical Security or transferred to a Person who
     takes delivery thereof in the form of a Physical Security which does not
     bear the Securities Act Legend if:

                   (A) such exchange or transfer is effected pursuant to the
             Exchange Registration Statement in accordance with the Registration
             Rights Agreement and the receipt by the Trustee of an Officers'
             Certificate stating that such events have occurred;

                   (B) any such transfer is effected pursuant to the Shelf
             Registration Statement in accordance with the Registration Rights
             Agreement and the receipt by the Trustee of an Officers'
             Certificate stating that such events have occurred; or

                   (C) the Registrar receives a certificate from such Holder in
             the form of Exhibit E hereto, including the certifications in item
             1(c) thereof and an Opinion of Counsel in form reasonably
             acceptable to the Company, to the
<PAGE>
 
                                      -38-

             effect that such exchange or transfer is in compliance with the
             Securities Act and, that the restrictions on transfer contained
             herein and in Section 2.6(f) hereof are not required in order to
             maintain compliance with the Securities Act.

             (iii) Exchange of Physical Securities.  When Physical Securities
     are presented by a Holder to the Registrar with a request to register the
     exchange of such Physical Securities for an equal principal amount of
     Physical Securities of other authorized denominations, the Registrar shall
     make the exchange as requested only if the Physical Securities are endorsed
     or accompanied by a written instrument of transfer in form satisfactory to
     the Registrar duly executed by such Holder or by his attorney duly
     authorized in writing and shall be issued only in the name of such Holder
     or its nominee and the transfer documentation required in Section
     2.6(d)(ii).  The Physical Securities issued in exchange for Physical
     Securities shall bear the Securities Act Legend and shall be subject to all
     restrictions on transfer contained herein in each case to the same extent
     as the Physical Securities so exchanged.

             (iv)  Return of Physical Securities.  In the event of a transfer
     pursuant to clauses (i) or (ii) above and the Holder thereof as delivered
     certificates representing an aggregate principal amount of Securities in
     excess of that to be transferred, the Company shall execute and the Trustee
     shall authenticate and deliver to the Holder of such Security without
     service charge, a new Physical Security or Securities of any authorized
     denomination requested by the Holder, in an aggregate principal amount
     equal to the portion of the Security not so transferred.

         (e) Exchange Offer.  Upon the occurrence of the Exchange Offer (as
defined in the Registration Rights Agreement) in accordance with the
Registration Rights Agreement, the Company shall issue and, upon receipt of an
Officers' Certificate stating that the Exchange Registration Statement has
become effective and that the Exchange Offer has occurred and an authentication
order in accordance with Section 2.2, the Trustee shall authenticate one or more
Unrestricted Global Securities in an aggregate principal amount equal to the
principal amount of the interests in the Initial Global Securities and
Restricted Physical Securities tendered for acceptance by persons participating
therein.  Concurrently with the issuance of such Securities, the Trustee shall
cause the aggregate principal amount of the applicable Initial Global Securities
to be reduced accordingly and direct DTC to make a corresponding reduction in
its book-entry system.  The Trustee shall cancel any Restricted Physical
Certificates in accordance with Section 2.9 hereof.

         In the case that one or more of the events specified in Section 2.6(a)
have occurred, upon the occurrence of such Exchange Offer, the Company shall
issue and, upon receipt of an authentication order in accordance with Section
2.2, the Trustee shall authent-

                                      -39-

icate Unrestricted Physical Securities in an aggregate principal amount equal to
the principal amount of the Restricted Physical Securities tendered for
acceptance by persons participating therein.

         (f)   Legends.

         Each Initial Global Security and each Restricted Physical Security
shall bear the legend (the "Securities Act Legend") in substantially the

in substantially the following form:

         "UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR
     SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE
     TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITORY TRUST COMPANY, A
     NEW YORK CORPORATION ("DTC") TO A NOMINEE OF DTC, OR BY ANY SUCH

         (h) Cancellation and/or Adjustment of Global Securities.  At such time
as all interests in the Global Securities have been exchanged for Physical
Securities, all Global Securities shall be returned to or retained and canceled
by the Trustee in accordance with Section 2.9 hereof.  At any time prior to such
cancellation, if any interest in a Global Security is exchanged for an interest
in another Global Security or for Physical Securities, the principal amount of
Securities represented by such Global Security shall be reduced accordingly and
all such changes to such Global Security shall be reflected on the books and
records of the Trustee, by the Trustee to reflect such reduction.

         (i)       General Provisions Relating to All Transfers and Exchanges.

             (i)   To permit registrations of transfers and exchanges, the
     Company shall execute and the Trustee shall authenticate Global Securities
     and Physical Securities upon a written order signed by an Officer of the
     Company or at the Registrar's request.

             (ii)  No service charge shall be made to a Holder for any
     registration of transfer or exchange, but the Company may require payment
     of a sum sufficient to cover any stamp or transfer tax or similar
     governmental charge payable in connection therewith (other than any such
     stamp or transfer taxes or similar governmental charge payable upon
     exchange or transfer pursuant to Sections 2.8 and 4.11 hereof).

             (iii) All Global Securities and Physical Securities issued upon
     any registration of transfer or exchange of Global Securities or Physical
     Securities shall be the valid obligations of the Company, evidencing the
     same debt, and entitled to the same benefits under this Indenture, as the
     Global Securities or Physical Securities surrendered upon such registration
     of transfer or exchange.

             (iv)  The Company shall not be required (A) to issue, to register
     the transfer of or to exchange Securities during a period beginning at the
     opening of business 15 days before the day of any selection of Securities
     for redemption and ending at the close of business on the day of selection,
     (B) to register the transfer of or to exchange any Security so selected for
     redemption in whole or in part, except the unredeemed portion of any
     Security being redeemed in part or (C) to register the transfer of or to
     exchange a Security between a record date and the next succeeding Interest
     Payment Date.

             (v)   Prior to due presentment for the registration of a transfer
     of any Security, the Trustee, any Agent and the Company may deem and treat
     the Person in whose name any Security is registered as the absolute owner
     of such Security for the purpose of receiving payment of principal of and
     interest on such Securities and for all other purposes, and none of the
     Trustee, any Agent or the Company shall be affected by notice to the
     contrary.

         Notwithstanding anything herein to the contrary, as to any
certification or certificate delivered to the Registrar pursuant to this Section
2.6, the Registrar's duties shall be limited to confirming that any such
certification or certificate delivered to it is in the form of Exhibit D or E
attached hereto.  The Registrar shall not be responsible for confirming the
truth or accuracy of any representations made in any such certification or
certificate.

                                     -42-

          SECTION 2.7  Replacement Securities.

          If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

          If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be reasonably required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company or the Trustee that such Security has been acquired by
a bona fide purchaser, the Company shall execute and upon its request the
Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or
stolen Security, a new Security of like tenor and principal amount, having
endorsed thereon and bearing a number not contemporaneously outstanding.

          Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

          Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

          SECTION 2.8  Temporary Securities.

          Pending the preparation of definitive Securities, the Company may
execute and, upon Company Order, the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued, and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.
<PAGE>
 
                                     -43-

          If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 10.2, without charge to
the Holder.  Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities of
authorized denominations and like tenor.  Until so exchanged the temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities.

          SECTION 2.9  Cancellation.

          All Securities surrendered for payment, redemption or registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly canceled by it.  The Company
may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Securities so delivered shall be
promptly canceled by the Trustee.  No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section,
except as expressly permitted by this Indenture.  All canceled Securities held
by the Trustee shall be destroyed by the Trustee and upon the Company's written
request, the Trustee shall deliver a certificate of destruction to the Company.

          SECTION 2.10  Defaulted Interest.

          Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

          (1)  The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Securities (or their respective
     Predecessor Securities) are registered at the close of business on a date
     for the payment of such Defaulted Interest (herein called a "Special Record
     Date"), which shall be fixed in the following manner. The Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each Security and the date of the proposed payment, and at
     the same time the Company shall deposit with the Trustee an amount of money
     equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited

                                     -44-

     to be held in trust for the benefit of the Persons entitled to such
     Defaulted Interest as in this clause provided. Thereupon the Company shall
     fix a Special Record Date for the payment of such Defaulted Interest which
     shall be not more than 15 days prior to the date of the proposed payment.

     and, in the name and at the expense of the Company, the Trustee shall cause
     notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor to be mailed, first-class postage prepaid, to each
     Holder at his address as it appears in the Security Register, not less than
     five Business Days prior to such Special Record Date. Notice of the
     proposed payment of such Defaulted Interest and the Special Record Date
     therefor having been so mailed, such Defaulted Interest shall be paid not
     later than the fifteenth day after such Special Record Date to the Persons
     in whose names the Securities (or their respective Predecessor Securities)
     are registered at the close of business on such Special Record Date.

          (2)  The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Securities may be listed, and upon such
     notice as may be required by such exchange, if, after notice given by the
     Company to the Trustee of the proposed payment pursuant to this clause,
     such manner of payments shall be deemed practicable by the Trustee.

          SECTION 2.11  CUSIP or CINS Number.

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

          SECTION 2.12  Payments of Interest.

          (a)  The Holder of a Physical Security at the close of business on the
Regular Record Date with respect to any Interest Payment Date shall be entitled
to receive the interest and Additional Interest, if any, payable on such
Interest Payment Date notwithstanding any transfer or exchange of such Physical
Security subsequent to the regular record date and prior to such Interest
Payment Date, except if and to the extent the Company shall default in the
payment of the interest or Additional Interest due on such Interest Payment
Date, in which case such Defaulted Interest and Additional Interest, if any,
shall be 
<PAGE>
 
                                     -45-

paid in accordance with Section 2.10; provided that, in the event of an exchange
of a Physical Security for a beneficial interest in any Global Security
subsequent to a regular record date or any special record date and prior to or
on the related Interest Payment Date or other payment date under Section 2.10,
any payment of the interest and Additional Interest payable on such payment date
with respect to any such Physical Security shall be made to the Person in whose
name such Physical Security was registered on such record date. Payments of
interest on the Global Securities will be made to the Holder of the Global
Security on each Interest Payment Date; provided that, in the event of an
exchange of all or a portion of a Global Security for Physical Security
subsequent to the regular record date or any special record date and prior to or
on the related Interest Payment Date or other payment date under Section 2.10
any payment of interest or Additional Interest payable on such Interest Payment
Date or other payment date with respect to the Physical Security shall be made
to the Holder of the Global Security.

          (b)  The Trustee shall pay interest and Additional Interest, if any,
to DTC, with respect to any Global Security held by DTC, on the applicable
Interest Payment Date in accordance with instructions received from the Company

the Securities, they shall notify the Trustee in writing of the redemption date,

Securities pursuant to which the redemption will occur.  The Company shall give
each notice to the Trustee provided for in this Section not less than 20 not

from the Company to the effect that such redemption will comply with the
provisions herein.

          SECTION 3.2  Selection of Securities To Be Redeemed.

          If fewer than all the Securities are to be redeemed, the Trustee shall
select the Securities to be redeemed pro rata or by lot or by a method that
complies with applicable legal and securities exchange requirements, if any, and
that the Trustee considers fair and appropriate and in accordance with methods
generally used at the time of selection by fiduciaries in similar circumstances.
The Trustee shall make the selection from outstanding Securities not previously
called for redemption.  The Trustee may select for redemption portions of the
principal of Securities that have denominations larger than $1,000.  Securities
and portions of them the Trustee selects shall be in amounts of $1,000 or a
whole multiple of $1,000.  Provisions of this Indenture that apply to Securities
called for redemption also apply to portions of Securities called for
redemption.  The Trustee shall notify the Company promptly of the Securities or
portions of Securities to be redeemed.  In the event the Company is required to
make an offer to repurchase Securities pursuant to Sections      or      and the
amount available for such offer is not evenly divisible by $1,000, the Trustee
shall promptly refund to the Company any remaining funds, which in no event will
exceed $1,000.

          SECTION 3.3  Notice of Redemption.

          At least 20 days but not more than 60 days before a date for
redemption of Securities, the Company shall mail a notice of redemption by
first-class mail to the registered address appearing in the Security Register of
each Holder of Securities to be redeemed.  The notice shall identify the
Securities (including CUSIP numbers, if any) to be redeemed and shall state:

          (1)  the redemption date;

          (2)  the redemption price;

          (3) the name and address of the Paying Agent;

          (4) that Securities called for redemption must be surrendered to
     the Paying Agent to collect the redemption price;

          (5) if fewer than all the outstanding Securities are to be
     redeemed, the identification and principal amounts of the particular
     Securities to be redeemed;

          (6) that, unless the Company defaults in making such redemption
     payment, interest on Securities (or portion thereof) called for redemption
     ceases to accrue on and after the redemption date;
<PAGE>
 
                                     -47-

          (7) the paragraph of the Securities pursuant to which the
     Securities called for redemption are being redeemed;

          (8) the CUSIP number, if any, printed on the Securities being
     redeemed; and

          (9) that no representation is made as to the correctness or
     accuracy of the CUSIP number, if any, listed in such notice or printed on
     the Securities.

          At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense.  In such event,
the Company shall provide the Trustee with the information required by this
Section.

          SECTION 3.4  Effect of Notice of Redemption.

          Once notice of redemption is mailed, Securities called for redemption
become due and payable on the redemption date and at the redemption price stated
in the notice.  Upon surrender to the Paying Agent, such Securities shall be
paid at the redemption price stated in the notice, plus accrued interest to the
redemption date.  Such notice if mailed in the manner herein provided shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice.  Failure to give notice or any defect in the notice to any Holder
shall not affect the validity of the notice to any other Holder.  On and after
the redemption date, interest will cease to accrue on Securities or portions
thereof called for redemption.

          SECTION 3.5  Deposit of Redemption Price.

          Prior to 11:00 a.m. (New York City time) on the redemption date, the
Company shall deposit with the Trustee or Paying Agent (or, if the Company or a
Subsidiary is the Paying Agent, shall segregate and hold in trust) money
sufficient to pay the redemption price of and accrued interest (if any) on all
Securities or portions thereof to be redeemed on that date other than Securities
or portions of Securities called for redemption which have been delivered by the
Company to the Trustee for cancellation.

          SECTION 3.6  Securities Redeemed In Part.

          Upon surrender of a Security that is redeemed in part (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing), the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities of any
authorized denomination as requested by such Holder, in aggregate 
<PAGE>
 
                                     -48-

principal amount equal to and in exchange for the unredeemed portion of the
principal of the Security so surrendered.

New York, an office or agency, where Securities may be surrendered for
registration of transfer or exchange or for presentation for payment and where
notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served.  The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or
agency.  If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
address of the Trustee set forth in Section 10.2.

          The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations;
provided that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York, for such purposes.  The Company will give
prompt written notice to the Trustee of any such designation or rescission and
of any change in the location of any such other office or agency.

existence and rights (charter and statutory), licenses and/or franchises of the
Company and each of its Subsidiaries; provided that the Company shall not be
required to preserve any such right, license or franchise, or the corporate
existence of any of its Subsidiaries, if in the reasonable and good faith
judgment of the Board of Directors of the Company (i) such preservation or
existence is not desirable in the conduct of business of the Company or such
Subsidiary and (ii) the loss of such right, license or franchise or the

Holders or to the Company or the ability of the Company to satisfy its
obligations hereunder.

Subsidiaries; provided 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 or validity is being contested in good faith
by appropriate negotiations or proceedings promptly instituted and diligently

betterments and improvements thereto; provided that nothing in this Section 4.5

maintenance of any of such properties, or disposing of any of them, if such
discontinu-

ance or disposal is (i) in the ordinary course of business, (ii) in the
reasonable and good faith judgment of the Board of Directors of the Company or

          The Company and each Subsidiary Guarantor covenants (to the extent
that it may lawfully do so) that it will not at any time insist upon, plead, or

had been enacted.

          SECTION 4.11  Change of Control.

Transaction"), other than Affiliate Transactions that are on terms that are fair
and reasonable to the Company or such Restricted Subsidiary of the Company and

unaffiliated party; provided that if the Company or any Restricted Subsidiary of
the Company enters into an Affiliate Transaction or series of Affiliate
Transactions involving or having an aggregate value of more than $20.0 million,
a majority of the disinterested members of the Board of Directors of the Company
or a committee thereof shall, prior to the consummation of such Affiliate
Transaction, have determined (as evidenced by a resolution thereof) that such

agreement as in effect on the Issue Date; (g) Restricted Payments permitted by
this Indenture; (h) loans or advances to employees or consultants in the
ordinary course of business and consistent with past practices in an aggregate

venture agreements) and otherwise in compliance with the terms of this Indenture
which are fair to the Company or its Restricted Subsidiaries, in the reasonable
determination of the senior management of the Company, or are on terms at least
as favorable as might reasonably have been obtained at such time from an
unaffiliated party; and (j) any employment or compensation arrangement entered
into by the Company or any of its Restricted Subsidiaries in the ordinary course

Liens granted by the Company on property or assets of the Company securing
Indebtedness of the Company that is permitted by this Indenture and that is
subordinated to the Securities; provided that the Securities are secured by
Liens ranking prior to such Liens; (iv) Permitted Liens; (v) Liens in respect of
Acquired Indebtedness permitted by this Indenture, provided, that the Liens in
respect of such Acquired Indebtedness secured such Acquired Indebtedness at the
time of the incurrence of such Acquired Indebtedness by the Company and such
Liens and the Acquired Indebtedness were not incurred by the Company or by the
Person being acquired or from whom the assets were acquired in connection with,
or in anticipation of, the incurrence of such Acquired Indebtedness by the
Company and provided, further that such Liens in respect of such Acquired
Indebtedness do not extend to or cover any property or assets of the Company or
of any Subsidiary of the Company other than the property or assets that secured
the Acquired Indebtedness prior to the time such Indebtedness became Acquired
Indebtedness of the Company; (vi) Liens granted in connection with any Qualified

allow to become effective any consensual encumbrance or restriction of any kind
on the ability of any such Restricted Subsidiary to (i) pay dividends, in cash
or otherwise, or make other payments or distributions on its Capital Stock or

owned by the Company or by any Restricted Subsidiary of the Company, or make
payments on any Indebtedness owed to the Company or to any Restricted Subsidiary
of the Company; (ii) make loans or advances to the Company or to any Restricted
Subsidiary of the Company; or (iii) transfer any of their respective property or

<PAGE>
 
                                      -59-

existing under or by reason of (A) applicable law or regulations; (B) customary
provisions restricting subletting or assignment of any lease governing a
leasehold interest of any Restricted Subsidiary of the Company; (C) Indebtedness
or any other contractual requirements (including pursuant to any corporate
governance documents in the nature of a charter or by-laws) of a Securitization
Subsidiary arising in connection with a Qualified Securitization Transaction;
provided that any such encumbrances and restrictions apply only to such
Securitization Subsidiary; (D) any agreement in effect on the Issue Date as any
such agreement is in effect on such date; (E) any agreement relating to any
Indebtedness incurred by such Restricted Subsidiary prior to the date on which

apply to any assets of the Company or its Restricted Subsidiaries other than
such Restricted Subsidiary; and (F) this Indenture.

          SECTION 4.15  Limitation on Guarantees by Restricted Subsidiaries.

          The Company shall not cause or permit any of its Restricted
Subsidiaries, directly or indirectly, to guarantee the payment of any
Indebtedness of the Company unless such Restricted Subsidiary of the Company
simultaneously executes and delivers a supplemental indenture (the substantive
provisions of which are in Exhibit B hereto) to this Indenture providing for the
guarantee of payment of the Securities (a "Subsidiary Guarantee") by such
Restricted Subsidiary of the Company (a "Subsidiary Guarantor"); provided any
guarantee by a Subsidiary Guarantor of such other Indebtedness (A) (1) (X) is
unsecured or (Y) is secured and (I) in the case of any such guarantee of Senior
Indebtedness of the Company, the Subsidiary Guarantee is secured equally and
ratably with any Liens securing such guarantee, subject to the provisions of
Article XI, (II) in the case of any such guarantee of Indebtedness of the
Company ranking pari passu with the Securities, the Subsidiary Guarantee is
secured equally and ratably with any Liens securing such guarantee, and (III) in
the case of any such guarantee of Indebtedness of the Company subordinated to
the Securities, the Subsidiary Guarantee is secured on a basis ranking prior to
the Liens securing such guarantee and (2) (X) in the case of any such guarantee
of Indebtedness of the Company subordinated or junior to the Securities (whether
pursuant to its terms or by operation of law), such guarantee is subordinated
pursuant to a written agreement to the Subsidiary Guarantee at least to the same
extent and in the same manner as such other Indebtedness is subordinated to the
Securities, or (Y) (I) in the case of any such guarantee of Senior Indebtedness
of the Company incurred in accordance with this Indenture, the Subsidiary
Guarantee is subordinated to Guarantor Senior Indebtedness of such Subsidiary
Guarantor to the same extent and in the same manner as the Securities are
subordinated to Senior Indebtedness of the Company or (II) the Subsidiary
Guarantee is not subordinated or junior to any 
<PAGE>
 
                                      -60-

Indebtedness of such Subsidiary Guarantor; and (B) such Subsidiary Guarantor
waives, and agrees it will not in any manner whatsoever claim or take the
benefit or advantage of, any rights of reimbursement, indemnity or subrogation
or any other rights against the Company or any other Subsidiary of the Company
as a result of any payment by it under such Subsidiary Guarantees.
Notwithstanding the foregoing, any Subsidiary Guarantee shall provide by its
terms that it shall be automatically and unconditionally released and discharged
upon either (A) the unconditional release or discharge of such Subsidiary
Guarantor's guarantees of all other Indebtedness of the Company (other than a
release resulting from payment under such Subsidiary Guarantor's guarantees) or
(B) any sale, exchange or transfer, to any Person not an Affiliate of the
Company, of all (but not less than all) of the Capital Stock of such Subsidiary
Guarantor, or all or substantially all of the assets of such Subsidiary
Guarantor, pursuant to a transaction which is in compliance with all of the
terms of the relevant Indenture.

          The supplemental indenture shall supplement this Indenture by, among
other things, creating an additional Article XII applicable to such Subsidiary
Guarantor and any other Subsidiary Guarantors in the form set forth in Exhibit B
hereto and, in connection with the execution and delivery of the supplemental
indenture, such Subsidiary Guarantor shall execute and deliver a Guarantee
substantially in the form of Exhibit C hereto.  Such Article XII shall not
become effective until the provisions of Section 12.2 have been complied with.

          Notwithstanding the foregoing, any Subsidiary Guarantee will be
subject to release under the conditions described in Section 12.4 of Exhibit B
hereto.

          SECTION 4.16  Limitation on Senior Subordinated Indebtedness.

          The Company will not directly or indirectly, in any event incur any
(a) Indebtedness that purports to be by its terms (or by the terms of any
agreement governing such Indebtedness) both subordinate to any other
Indebtedness of the Company and senior or superior in any right of payment or
interest to the Securities or (b) Indebtedness which by its terms (or by the
terms of any agreement governing such Indebtedness) is subordinated to any other
Indebtedness of the Company (other than Indebtedness of the Company that is
subordinated solely to Senior Indebtedness of the Company) unless such
Indebtedness is also by its terms (or by the terms of any agreement governing
such Indebtedness) made expressly subordinate to the Securities to the same
extent and in the same manner as such Indebtedness is subordinated pursuant to
subordination provisions that are most favorable to the holders of any other
Indebtedness of the Company.

          The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, (i) declare or pay any
dividend, or make any distribution of any kind or character (whether in cash,
property or securities), in respect of any class of its Capital Stock or to the
holders thereof in their capacity as stockholders, excluding any (x) dividend or
distributions payable solely in shares of its Qualified Capital Stock or in
options, warrants or other rights to acquire its Qualified Capital Stock or (y)
in the case of any Restricted Subsidiary of the Company, dividends or
distributions payable to the Company or a Restricted Subsidiary of the Company;
(ii) purchase, redeem, or otherwise acquire or retire for value shares of
Capital Stock of the Company or a Restricted Subsidiary of the Company, any
securities convertible or exchangeable into shares of Capital Stock of the
Company or a Restricted Subsidiary of the Company or any options, warrants or
rights to purchase or acquire shares of Capital Stock of the Company or a
Restricted Subsidiary of the Company, excluding any such shares of Capital
Stock, options, warrants, rights or securities which are owned by the Company or
a Restricted Subsidiary of the Company; (iii) make any Investment (other than a
Permitted Investment) in, or payment on a guarantee of any obligation of, any
Person; or (iv) redeem, defease, repurchase, retire or otherwise acquire or
retire for value, prior to any scheduled maturity, repayment or sinking fund
payment, Indebtedness which is subordinate in right of payment to the Securities
(each of the transactions described in clauses (i) through (iv) (other than any
exception to any such clause) being a "Restricted Payment") if at the time
thereof:

             (1) an Event of Default, or an event that with the passing of time
     or giving of notice, or both, would constitute an Event of Default, shall
     have occurred and be continuing, or

             (2) upon giving effect to such Restricted Payment, the Company
     could not incur at least $1.00 of additional Indebtedness pursuant to the
     terms of this Indenture described in clause (i) of Section 4.9, or

             (3) upon giving effect to such Restricted Payment, the aggregate of
     all Restricted Payments made on or after the Issue Date exceeds the sum
     (without duplication) of:  (a) 50% of cumulative Consolidated Net Income of
     the Company (or, in the case cumulative Consolidated Net Income of the
     Company shall be negative, 
<PAGE>
 
                                      -62-

     less 100% of such deficit) for the period (treated as an accounting period)
     from the Issue Date through the last day of the Company's most recently
     ended fiscal quarter for which financial statements are available, plus (b)
     100% of the aggregate net cash proceeds received after the Issue Date,
     including the fair market value of readily marketable securities from the
     issuance of Qualified Capital Stock of the Company and warrants, rights or
     options on Qualified Capital Stock of the Company (other than in respect of
     any such issuance to a Subsidiary of the Company) and the principal amount
     of Indebtedness of the Company or a Subsidiary of the Company that has been
     converted into or exchanged for Qualified Capital Stock of the Company
     which Indebtedness was incurred after the Issue Date; plus (c) in the case
     of the disposition or repayment of any Investment constituting a Restricted
     Payment made after the Issue Date, an amount equal to the lesser of the
     return of capital with respect to such Investment and the cost of such
     Investment, in either case, less the cost of the disposition of such
     Investment; provided that at the time any such Investment is made the
     Company delivers to the Trustee a resolution of the Board of Directors of
     the Company to the effect that, for purposes of this Section 4.18 covenant,
     such Investment constitutes a Restricted Payment made after the Issue Date;
     plus (d) an amount equal to the sum of (i) the net reduction in Investments
     in Unrestricted Subsidiaries resulting from the receipt of dividends,
     repayments of loans or advances or other transfers of assets or proceeds
     from the disposition of Capital Stock or other distributions or payments,
     in each case to the Company or any Restricted Subsidiary from, or with
     respect to, interests in Unrestricted Subsidiaries, and (ii) the portion
     (proportionate to the Company's equity interest in such Subsidiary) of the
     fair market value of the net assets of an Unrestricted Subsidiary at the
     time such Unrestricted Subsidiary is designated a Restricted Subsidiary;
     provided that the foregoing sum shall not exceed, in the case of any
     Unrestricted Subsidiary, the amount of Investments previously made (and
     treated as a Restricted Payment) by the Company or any Restricted
     Subsidiary in such Unrestricted Subsidiary subsequent to the Issue Date;
     plus (e) $25.0 million. For purposes of determining the amount expended for
     Restricted Payments under this clause (3), property other than cash shall
     be valued at its fair market value.

          Notwithstanding the foregoing, the provisions set forth in the
immediately preceding paragraph will not prohibit (i) any dividend on any class
of Capital Stock of the Company or any of its Restricted Subsidiaries paid

was declared, the Company or any of its Restricted Subsidiaries, as the case may
be, could have paid such dividend in accordance with the provisions of this
Indenture, (ii) the renewal, extension, refunding or refinancing of any
Indebtedness otherwise permitted pursuant to the terms of this Indenture

case as approved by the Board of Directors of the Company in its good faith
judgment, (v) so long as no Default or Event of Default has occurred and is
continuing, any Investment made with the proceeds of a substantially concurrent

such sale of Qualified Capital Stock shall not be (and have not been) included
in clause (3) of the preceding paragraph, (vi) the redemption, repurchase,
retirement or other acquisition of any Capital Stock of the Company in exchange
for or out of the net cash proceeds of the substantially concurrent sale (other
than to a Restricted Subsidiary of the Company) of Qualified Capital Stock of
the Company; provided that the proceeds of such sale of Capital Stock shall not
be (and have not been) included in clause (3) of the preceding paragraph, (vii)
so long as no Event of Default has occurred and is continuing, the redemption,
repurchase, retirement or other acquisition of any Subordinated Indebtedness of
the Company in exchange for or out of the net cash proceeds of the substantially

effect to such Investment, the Company could incur at least $1.00 of additional
Indebtedness pursuant to the terms of this Indenture described in clause (i) of

(xiii) and (xiv) of the previous sentence shall be taken into account (and the
Restricted Payments described in the remaining clauses shall not be taken into
account) for purposes of computing the aggregate amount of all Restricted
Payments made pursuant to clause (3) of the preceding paragraph.

          SECTION 4.19  Limitation on Certain Asset Dispositions.

          The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, make one or more Asset

may be, receives consideration for such Asset Disposition at least equal to the
fair market value of the assets sold or disposed of (as determined in good faith
by the Company); (ii) not less than 75% of the consideration for the disposition
consists of cash or readily marketable cash equivalents or the assumption of
Indebtedness (other than non-recourse Indebtedness or any Indebtedness

subordinate to the applicable issue of Notes) then outstanding (including a
permanent reduction of commitments in respect thereof) or (B) the permanent
reduction and repayment of any Indebtedness of any Restricted Subsidiary of the
Company then outstanding (including a permanent reduction of commitments in
respect thereof).  The 361st day after such Asset Disposition shall be deemed to
be the "Asset Sale Offer Trigger Date," and the amount of Net Available Proceeds
from Asset Dispositions otherwise subject to the preceding provisions not so
applied or as to which the Company has determined not to so apply shall be
referred to as the "Unutilized Net Available Proceeds." Within fifteen days
after the Asset Sale Offer Trigger Date, the Company shall make an Offer to
Purchase the outstanding applicable issue of Securities at a purchase price in
cash equal to 100% of their principal amount plus any accrued and unpaid
interest thereon to the Purchase Date.  Notwithstanding the foregoing, the
<PAGE>
 
                                      -65-

Company may defer making any Offer to Purchase outstanding Securities until
there are aggregate Unutilized Net Available Proceeds equal to or in excess of
$25.0 million (at which time, the entire Unutilized Net Available Proceeds, and
not just the amount in excess of $25.0 million, shall be applied as required
pursuant to this paragraph).  Pending application of the Unutilized Net
Available Proceeds pursuant to this covenant, such Unutilized Net Available
Proceeds shall be invested in Permitted Investments of the types described in
clauses (i), (ii) and (iii) of the definition of "Permitted Investments."

          If any Indebtedness of the Company or any of its Restricted
Subsidiaries ranking pari passu with the Securities requires that prepayment of,
or an offer to prepay, such Indebtedness be made with any Net Available
Proceeds, the Company may apply such Net Available Proceeds pro rata (based on
the aggregate principal amount of the Securities then outstanding and the
aggregate principal amount (or accreted value, if less) of all such other
Indebtedness then outstanding) to the making of an Offer to Purchase the
Securities in accordance with the foregoing provisions and the prepayment or the
offer to prepay such pari passu Indebtedness.  Any remaining Net Available
Proceeds following the completion of the required Offer to Purchase may be used
by the Company for any other purpose (subject to the other provisions of this
Indenture) and the amount of Net Available Proceeds then required to be
otherwise applied in accordance with this covenant shall be reset to zero,
subject to any subsequent Asset Disposition.  These provisions will not apply to
a transaction consummated in compliance with Article V.

          Notwithstanding the foregoing, the provisions of this covenant shall
not apply to any Sale/Leaseback Transaction with respect to the purchase of
tooling and related manufacturing equipment in the ordinary course of business
consistent with past practices.

          In the event that the Company makes an Offer to Purchase the
Securities, the Company shall comply with any applicable securities laws and
regulations, including any applicable requirements of Section 14(e) of, and Rule
14e-1 under, the Exchange Act and any violation of the provisions of this
Indenture relating to such Offer to Purchase occurring as a result of such
compliance shall not be deemed an Event of Default or an event that with the
passing of time or giving of notice, or both, would constitute an Event of
Default.

          SECTION 4.20  Limitation on Sale/Leaseback Transactions.

          The Company shall not, and shall not cause or permit any Restricted
Subsidiary to, enter into any Sale/Leaseback Transaction with respect to any
property unless (i) the Company or such Restricted Subsidiary would be entitled
to (A) incur Indebtedness in an amount equal to the Attributable Indebtedness
with respect to such Sale/Leaseback Transaction pursuant to clause (i) of
Section 4.9 and (B) create a Lien on such property securing such Attributable
Indebtedness without securing the Securities pursuant to Section 
<PAGE>
 
                                      -66-

4.13, (ii) the net proceeds received by the Company or any Restricted Subsidiary
in connection with such Sale/Leaseback Transaction are at least equal to the
fair value (as determined by the Board of Directors) of such property and (iii)
the Company applies the proceeds of such transaction in compliance with Section
4.19. Notwithstanding the foregoing, the provisions of this covenant shall not
prohibit the Company or any Restricted Subsidiary from entering into any
Sale/Leaseback Transaction with respect to the purchase of tooling and related
manufacturing equipment in the ordinary course of business consistent with past
practices.

substantially all of its assets to, the Company or another Restricted Subsidiary
of the Company without complying with clause (ii) of the above, (y) a series of

compliance with Section 4.18.

          For purposes of the foregoing, the transfer (by lease, assignment,
sale or otherwise, in a single transaction or series of transactions) of all or
substantially all of the properties or assets of one or more Restricted
Subsidiaries of the Company, the Capital Stock of which constitutes all or

     Indebtedness for money borrowed by the Company or any Subsidiary of the
     Company (or the payment of which is guaranteed by the Company or any
     Restricted Subsidiary of the Company), which default results in the
     acceleration of such Indebtedness prior to its express maturity and the
     principal amount of any such Indebtedness, together with the principal
     amount of any other such Indebtedness the maturity of which has been so

                   (F) shall admit in writing its inability to pay its debts
          generally; or

             (viii)a court of competent jurisdiction enters an order or decree
     under any Bankruptcy Law that:

                   (A) is for relief against the Company or any of its Material

<PAGE>
 
                                      -70-

          Material Subsidiaries, and in each case the order or decree remains
          unstayed and in effect for 60 days.

          (b) For purposes of this Section 6.1, the term "Custodian" means any
receiver, trustee, assignee, liquidator, sequestrator or similar official
charged with maintaining possession or control over property for one or more
creditors.

          SECTION 6.2  Acceleration.

          If an Event of Default (other than an Event of Default specified in
clauses (vii) and (viii) of Section 6.1(a) involving the Company) occurs and is
continuing, then and in every such case the Trustee or the Holders of not less
than 25% in aggregate principal amount of the Securities then outstanding may,
and the Trustee shall upon the request of Holders of not less than 25% in
aggregate principal amount of the Securities then outstanding, declare the
unpaid principal of, premium, if any, and accrued and unpaid interest on all the
Securities then outstanding to be due and payable, by a notice in writing to the
Company (and to the Trustee, if given by Holders) and upon such declaration such
principal amount, premium, if any, and accrued and unpaid interest will become
immediately due and payable, notwithstanding anything contained in this
Indenture or the Securities to the contrary, but subject to the provisions
limiting payment described in Article XI.  If an Event of Default specified in
clauses (vii) and (viii) of Section 6.1(a) involving the Company occurs, all
unpaid principal of, and premium, if any, and accrued and unpaid interest on the
Senior Notes and the Securities then outstanding will ipso facto become due and
payable, subject to the prior payment in full of all Senior Indebtedness of the
Company, without any declaration or other act on the part of the Trustee or any
Holder.

          SECTION 6.3  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 Securities or to enforce the
performance of any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which such judgment has been
recovered.

                                      -71-

          SECTION 6.4  Waiver of Past Default.

          Subject to Sections 6.7 and 9.2, the Holders of, in the aggregate, at
least a majority in principal amount of the then outstanding Securities by
notice to the Trustee may waive an existing Default or Event of Default and its
consequences, except a Default or Event of Default specified in Section
6.1(a)(i) or (ii) or a Default or Event of Default in respect of any provision
hereof which cannot be modified or amended without the consent of the Holder so
affected pursuant to Section 9.2.  When a Default or Event of Default is so
waived, it shall be deemed cured and cease to exist; but no such waiver shall
extend to any subsequent or other Default or Event of Default or impair any
right consequent thereto.

          SECTION 6.5  Control by Majority.

          The Holders of a majority in principal amount of the then outstanding
Securities may (i) 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 6.3, and (ii) direct the Trustee to notify each trustee under any
instrument governing the rights of holders of Indebtedness subordinated in right
of payment to the Securities for the purpose of effecting the payment blockage
provisions thereunder.  The Trustee may refuse, however, to follow any direction
that conflicts with law, the Securities or this Indenture, or that the Trustee
determines may be unduly prejudicial to the rights of another Securityholder
(provided, however, that subject to Section 7.1, the Trustee shall have no duty
or obligation to ascertain whether or not such direction is unduly prejudicial
to such Securityholder), that may involve the Trustee in personal liability or
if the Trustee determines that it does not have adequate indemnification against
any loss or expense; provided that the Trustee may take any other action deemed
proper by the Trustee which is not inconsistent with such direction.

          SECTION 6.6  Limitation on Suits.

          A Securityholder may not pursue any remedy with respect to this
Indenture or the Securities unless:

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

          (b) the Holders of at least 25% in principal amount of the then
     outstanding Securities make a written request to the Trustee to pursue a
     remedy;
<PAGE>
 
                                      -72-

          (c) such Holder or Holders offer and, if requested, provide to the
     Trustee indemnity reasonably satisfactory to the Trustee against any loss,
     liability or expense;

          (d) the Trustee does not comply with the request within 30 days after
     receipt of the request; and

          (e) during such 30-day period the Holders of at least a majority in
     principal amount of the then outstanding Securities do not give the Trustee
     a direction which is inconsistent with the request.

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

          SECTION 6.7  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 Security, on or
after the respective due dates expressed in the Security, or to bring suit for
the enforcement of any such payment on or after such respective dates, is
absolute and unconditional and shall not be impaired or affected without the
consent of such Holder.

          SECTION 6.8  Collection Suit by Trustee.

          If an Event of Default specified in Section 6.1(a)(i) or (ii) occurs
and is continuing, the Trustee may recover judgment in its own name and as
trustee of an express trust against the Company or any other obligor on the
Securities for the whole amount of principal and accrued interest remaining
unpaid, together with interest overdue on principal and, to the extent that
payment of such interest is lawful, interest on overdue installments of
interest, in each case at the Interest Rate 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 6.9  Trustee May File Proofs of Claim.

          The Trustee shall be entitled and empowered to 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, disbursements and advances of the Trustee, its agents
and counsel) and the Securityholders allowed in any judicial proceedings
relative to the Company or any of its Subsidiaries (or any other obligor upon
the Securities), its creditors or its property and shall be entitled and
empowered to collect and receive any monies or other property payable or
deliverable on any such claims 
<PAGE>
 
                                      -73-

and to distribute the same, and any Custodian in any such judicial proceedings
is hereby authorized by each Securityholder 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 Securityholders, to pay to the Trustee any amount due to it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agent and counsel, and any other amounts due the Trustee under
Section 7.7. Nothing herein contained shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Securityholder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Securityholder in any such proceeding.

          SECTION 6.10  Priorities.

          If the Trustee collects any money pursuant to this Article VI, it
shall, subject to the provisions of Article XI hereof, pay out such money in the
following order:

     First:  to the Trustee for all costs and expenses of collection and for all
     other amounts due under Section 7.7;

     Second: subject to Article XI, to Holders for interest accrued on the
     Securities, ratably, without preference or priority of any kind, according
     to the amounts due and payable on the Securities for interest; and

     Third:  subject to Article XI, to Holders for principal amounts owing under
     the Securities, ratably, without preference or priority of any kind,
     according to the amounts due and payable on the Securities for principal.

          The Trustee, upon prior written notice to the Company, may fix a
record date and payment date for any payment to Securityholders 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, 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 6.7, or a suit by any Holder, or group of Holders, holding
in the aggregate more than 10% in principal amount of the outstanding
Securities.
<PAGE>
 
                                      -74-

          SECTION 6.12  Rights and Remedies Cumulative.

          No right or remedy herein conferred upon or reserved to the Trustee or
to the Holders is intended to be exclusive of any other right or remedy, and
every remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

          SECTION 6.13  Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein.  Every right and remedy given by this Article 6 or by
law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

          SECTION 6.14  Restoration of Rights and Remedies.

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture 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 case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
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 VII


                                    TRUSTEE

          SECTION 7.1  Duties of Trustee.

          (a) If an Event of Default known to the Trustee 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 their exercise
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:
<PAGE>
 
                                      -75-

              (i)    The Trustee need perform only those duties as are
     specifically set forth in this Indenture or the TIA and no others and no
     implied covenants or obligations shall be read into this Indenture against
     the Trustee.

              (ii)   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 opinions which by any provision
     hereof are specifically required to be furnished to the Trustee, the
     Trustee shall examine such certificates and opinions to determine whether
     or not they conform to the requirements of this Indenture.

          (c) Notwithstanding anything to the contrary herein contained, the
Trustee may not be relieved from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that:

          (i)    This paragraph does not limit the effect of paragraph (b) of
     this Section 7.1.

          (ii)   The Trustee shall not be liable for any error of judgment made
     in good faith by a Trust Officer, unless it is proved that the Trustee was
     negligent in ascertaining the pertinent facts.

          (iii)  The Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Sections 6.2, 6.4 and 6.5.

          (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 of any of its duties hereunder or in the exercise of any of its
rights or powers 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 7.1.

          (f) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree in writing with the Company.  Money held
in trust by the Trustee need not be segregated from other funds except to the
extent required by law.

          SECTION 7.2  Rights of Trustee.

          Subject to Section 7.1:

          (a) The Trustee may rely and shall be protected in acting or
     refraining from acting upon any document reasonably believed by it to be
     genuine and to have been signed or presented by the proper Person.  The
     Trustee shall not be bound to make any investigation into the facts or
     matters stated in any resolution, certificate, statement, instrument,
     opinion, report, notice, request, direction, consent, order, bond,
     debenture, note, other evidence of indebtedness 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, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled during normal business hours and upon reasonable advance
     notice to the Company to examine the books, records and premises of the
     Company, personally or by agent or attorney.

          (b) Before the Trustee acts or refrains from acting with respect to
     any matter contemplated by this Indenture, it may require an Officers'
     Certificate or an Opinion of Counsel, which shall conform to the provisions
     of Section 10.5.  The Trustee shall not be liable for any action it takes
     or omits to take in good faith in reliance on such certificate or opinion.

          (c) The Trustee may act through its attorneys and agents and shall not
     be responsible for the misconduct or negligence of any agent (other than
     the negligence or willful misconduct of an agent who is an employee of the
     Trustee) appointed with due care.

          (d) The Trustee shall not be liable for any action it takes or omits
     to take in good faith and without negligence which it reasonably believes
     to be authorized or within its rights or powers conferred upon it by this
     Indenture or the TIA.

          (e) Before the Trustee acts or refrains from acting, it may consult
     with counsel and the advice or opinion of such counsel as to matters of law
     shall be full and complete authorization and protection from liability in
     respect of any action taken, omitted or suffered by it hereunder in good
     faith and in accordance with the advice or opinion of such counsel.

          (f) The Trustee shall not be required to give any bond or surety in
     respect of the performance of its powers and duties hereunder.
<PAGE>
 
                                      -77-

          (g) The permissive rights of the Trustee to do things enumerated in
     this Indenture shall not be construed as a duty.

          (h) The Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Securityholders unless such Securityholders shall have
     offered to the Trustee security or indemnity reasonable to it against the
     costs, expenses and liabilities that might be incurred by it in compliance
     with such request or direction.

          (i) Except for (i) default under Section 6.1(a)(i) or (ii) hereof, or
     (ii) any other event of which the Trustee has "actual knowledge" and which
     event, with the giving of notice or the passage of time or both, would
     constitute an Event of Default under this Indenture, the Trustee shall not
     be deemed to have notice of any default or Event of Default unless
     specifically notified in writing of such event by the Company or the
     Holders of not less than 25% in aggregate principal amount of the
     Securities then outstanding; as used herein, the term "actual knowledge"
     means the actual fact or statement of knowing, without any duty to make any
     investigation with regard thereto.

          SECTION 7.3  Individual Rights of Trustee.

          The Trustee in its individual capacity or any other capacity may
become the owner or pledgee of Securities and may otherwise deal with the
Company, or its Subsidiaries and 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 is subject to Sections 7.10 and 7.11.

          SECTION 7.4  Trustee's Disclaimer.

          The Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Securities, and it shall
not be accountable for the Company's use of the proceeds from the Securities or
for the use or application of any money received by any Paying Agent other than
the Trustee, and it shall not be responsible for any statement of the Company in
this Indenture or any other document in connection with the sale of the
Securities, or any statement in the Securities other than the Trustee's
certificate of authentication.

          SECTION 7.5  Notice of Defaults.

          If a Default or an Event of Default with respect to the Securities
occurs and is continuing and the Trustee receives written notice of such Default
or Event of Default, the Trustee shall mail to each Securityholder notice of the
Default or Event of Default 
<PAGE>
 
                                      -78-

within 60 days after the occurrence thereof in accordance with TIA (S)313(c).
Except in the case of a Default or an Event of Default in payment of principal
of or interest on any Security, including on acceleration, and the failure to
make payment when required by Section 4.11, and except in the case of a failure
to comply with Article V hereof, the Trustee may withhold the notice to the
Securityholders for a period not to exceed 60 days if and so long as a committee
of its Trust Officers in good faith determines that withholding the notice is in
the interest of Securityholders.

          SECTION 7.6  Reports by Trustee to Holders.

          To the extent required by TIA (S)313(a), within 45 days after June 1
of each year commencing with 1998 and for as long as there are Securities
outstanding hereunder, the Trustee shall mail to each Securityholder the
Company's brief report dated as of such date that complies with TIA (S)313(a).
The Trustee also shall comply with TIA (S)313(b) and TIA (S)313(c) and (d).  A
copy of such report at the time of its mailing to Securityholders shall be filed
with the SEC, if required, and each stock exchange, if any, on which the
Securities are listed.

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

          SECTION 7.7  Compensation and Indemnity.

          The Company shall pay to the Trustee, the Paying Agent and the
Registrar from time to time reasonable compensation for their respective
services rendered hereunder.  The Trustee's, the Paying Agent's and the
Registrar's compensation shall not be limited by any law on compensation of a
trustee of an express trust.  The Company shall reimburse the Trustee, the
Paying Agent and the Registrar upon request for all reasonable out-of-pocket
disbursements, expenses and advances (including reasonable fees and expenses of
counsel) incurred or made by each of them in connection with entering into this
Indenture the performance of its duties under this Indenture in addition to the
compensation for their respective services under this Indenture.  Such expenses
shall include the reasonable compensation, out-of-pocket disbursements and
expenses of the Trustee's, the Paying Agent's and the Registrar's agents and
counsel.

          The Company shall indemnify the Trustee, the Paying Agent and the
Registrar for, and hold each of them harmless against, any claim, demand,
expense (including but not limited to attorneys' fees and expenses), loss or
liability incurred by each of them arising out of or in connection with the
administration of this Indenture and their respective duties hereunder.  Each of
the Trustee, the Paying Agent and the Registrar shall notify the Company
promptly of any claim asserted against it for which it may seek indemnity.
How-
<PAGE>
 
                                      -79-

ever, failure by the Trustee, the Paying Agent or the Registrar to so notify the
Company shall not relieve the Company of its obligations hereunder. The Company
need not reimburse any expense or indemnify against any loss or liability
incurred by the Trustee, the Paying Agent or the Registrar through the
Trustee's, the Paying Agent's or the Registrar's, as the case may be, own
willful misconduct or negligence.

          To secure the Company's payment obligations in this Section 7.7, each
of the Trustee, the Paying Agent and the Registrar shall have a lien prior to
the Securities on all money or property held or collected by it, in its capacity
as Trustee, Paying Agent or Registrar, as the case may be, except money or
property held in trust to pay principal of or interest on particular Securities.
Such lien shall survive the satisfaction and discharge of this Indenture.

          When any of the Trustee, the Paying Agent and the Registrar incurs
expenses or renders services after an Event of Default specified in Section
6.1(a)(vii) or (viii) occurs, the expenses and the compensation for the services
are intended to constitute expenses of administration under any Bankruptcy Law.

          SECTION 7.8  Replacement of Trustee.

          The Trustee may resign at any time 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
Securities may remove the Trustee by so notifying 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:

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

          (b) the Trustee is adjudged a bankrupt or an insolvent;

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

          (d) 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 Trustee in such event being referred to
herein as the retiring Trustee), the Company 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 Securities may appoint a successor
Trustee to replace the successor Trustee appointed by the Company.
<PAGE>
 
                                      -80-

          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 7.7), 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
Securityholder.

          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 25% in principal amount of then outstanding Securities 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 Securityholder
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
7.8, the Company's obligations under Section 7.7 shall continue for the benefit
of the retiring Trustee.

          SECTION 7.9  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  or national banking association without any further act
shall be the successor Trustee; provided such corporation or national banking
association shall be otherwise qualified and eligible under this Article VII.

          SECTION 7.10  Eligibility; Disqualification.

          This Indenture shall always have a Trustee who satisfies the
requirements of TIA (S)310(a)(1) and (2).  The Trustee shall have a combined
capital and surplus of at least $200,000,000 as set forth in its most recent
published annual report of condition.  The Trustee shall comply with TIA
(S)310(b); provided 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.  The provisions of TIA (S)310 shall apply to the Company,
as obligor of the Securities.

                                      -81-

          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.  The
provisions of TIA (S)311 shall apply to the Company as obligor on the
Securities.

                                  ARTICLE VIII


                    SATISFACTION AND DISCHARGE OF INDENTURE

          SECTION 8.1  Termination of the Company's Obligations.

          The Company's obligations under the Securities and this Indenture
shall terminate, and the obligations of any Subsidiary Guarantor shall
terminate, except those obligations referred to in the penultimate paragraph of
this Section 8.1, if all Securities previously authenticated and delivered
(other than destroyed, lost or stolen Securities which have been replaced or
paid or Securities for whose payment money has theretofore been deposited with
the Trustee or the Paying Agent in trust or segregated and held in trust by the
Company and thereafter repaid to the Company, as provided in Section 8.4) have
been delivered to the Trustee for cancellation and the Company has paid all sums
payable by it hereunder, or if:

          (a) all Securities have otherwise become due and payable hereunder;

          (b) the Company shall have irrevocably deposited or caused to be
     deposited with the Trustee or a trustee satisfactory to the Trustee, 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 Holders for that purpose, cash or cash equivalents in such amount as
     is sufficient without consideration of reinvestment of such interest, to
     pay principal of, premium, if any, and interest on the outstanding
     Securities to maturity or redemption; provided that the Trustee shall have
     been irrevocably instructed to apply such cash or cash equivalents to the
     payment of said principal, premium, if any, and interest with respect to
     the Securities, and; provided, further, that from and after the time of
     deposit, the money deposited shall not be subject to the rights of holders
     of Senior Indebtedness of the Company or Guarantor Senior Indebtedness
     pursuant to the provisions of Article XI or Article XII;

          (c) no Default or Event of Default with respect to this Indenture or
     the Securities shall have occurred and be continuing on the date of such
     deposit or shall 
<PAGE>
 
                                      -82-

     occur as a result of such deposit and such deposit will not result in a
     breach or violation of, or constitute a default under, any other instrument
     to which the Company is a party or by which it is bound;

          (d) the Company shall have paid all other sums payable by it
     hereunder;

          (e) the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent providing for the termination of the Company's and each
     Subsidiary Guarantor's obligation under the Securities and this Indenture
     have been complied with. Such Opinion of Counsel shall also state that such
     satisfaction and discharge does not result in a default under any Senior
     Indebtedness of the Company (if then in effect) or any other agreement or
     instrument then known to such counsel that binds or affects the Company.

          Notwithstanding the foregoing paragraph, the Company's obligations in
Sections 2.5, 2.6, 2.7, 2.8, 4.1, 4.2 and 7.7 and any Subsidiary Guarantor's
obligations in respect thereof shall survive until the Securities are no longer
outstanding.  After the Securities are no longer outstanding, the Company's
obligations in Sections 7.7, 8.4 and 8.5 and any Subsidiary Guarantor's
obligations in respect thereof shall survive.

          After such delivery or irrevocable deposit the Trustee upon request
shall acknowledge in writing the discharge of the Company's and any Subsidiary
Guarantor's obligations under the Securities and this Indenture except for those
surviving obligations specified above.

          SECTION 8.2  Legal Defeasance and Covenant Defeasance.

          (a) The Company may, at its option and at any time, with respect to
the Securities, elect to have either paragraph (b) or paragraph (c) below be
applied to the outstanding Securities upon compliance with the conditions set
forth in paragraph (d).

          (b) Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (b), the Company and any Subsidiary Guarantor shall
be deemed to have been released and discharged from its obligations with respect
to the outstanding Securities on the date the conditions set forth below are
satisfied (hereinafter, "legal defeasance").  For this purpose, such legal
defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by the outstanding Securities, which shall
thereafter be deemed to be "outstanding" only for the purposes of paragraph (c)
below and the other Sections of and matters under this Indenture referred to in
(i) and (ii) below, and to have satisfied all its other obligations under such
Securities and this 
<PAGE>
 
                                      -83-


Indenture insofar as such Securities are concerned (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the
same), and Holders of the Securities and the Subsidiary Guarantees and any
amounts deposited under paragraph (d) below shall cease to be subject to any
obligations to, or the rights of, any holder of Senior Indebtedness of the
Company or Guarantor Senior Indebtedness under Article XI, Article XII or
otherwise, except for the following which shall survive until otherwise
terminated or discharged hereunder: (i) the rights of Holders of outstanding
Securities to receive solely from the trust fund described in paragraph (d)
below and as more fully set forth in such paragraph, payments in respect of the
principal of, premium, if any, and interest on such Securities when such
payments are due, (ii) the Company's obligations with respect to such Securities
under Sections 2.6, 2.7 and 4.2, and, with respect to the Trustee, under Section
7.7 and any Subsidiary Guarantor's obligations in respect thereof, (iii) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv)
this Section 8.2 and Section 8.5. Subject to compliance with this Section 8.2,
the Company may exercise its option under this paragraph (b) notwithstanding the
prior exercise of its option under paragraph (c) below with respect to the
Securities.

          (c) Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (c), the Company shall be released and discharged
from its obligations under any covenant contained in Article V and Article XI
and in Sections 4.5 through 4.9, 4.11 through 4.20 and Section 5.1 with respect
to the outstanding Securities on and after the date the conditions set forth
below are satisfied (hereinafter, "covenant defeasance"), and the Securities
shall thereafter be deemed to be not "outstanding" for the purpose of any
direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder and Holders
of the Securities and the Subsidiary Guarantees and any amounts deposited under
paragraph (d) below shall cease to be subject to any obligations to, or the
rights of, any holder of Senior Indebtedness of the Company or Guarantor Senior
Indebtedness under Article XI, Article XII or otherwise.  For this purpose, such
covenant defeasance means that, with respect to the outstanding Securities, the
Company and any Subsidiary Guarantor may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section
6.1(a)(iv), but, except as specified above, the remainder of this Indenture and
such Securities shall be unaffected thereby.

          (d) The following shall be the conditions to application of either
paragraph (b) or paragraph (c) above to the outstanding Securities:
<PAGE>
 
                                      -84-

             (i)    the Company shall irrevocably have deposited or caused to be
     deposited with the Trustee as trust funds in trust for the purpose of
     making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of such Securities, (x)
     money in an amount or (y) direct non-callable obligations of, or non-
     callable obligations guaranteed by, the United States of America for the
     payment of which guarantee or obligation the full faith and credit of the
     United States is pledged ("U.S. Government Obligations") maturing as to
     principal, premium, if any, and interest in such amounts of money and at
     such times as are sufficient without consideration of any reinvestment of
     such interest, to pay principal of and interest on the outstanding
     Securities not later than one day before the due date of any payment, or
     (z) 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 and
     which shall be applied by the Trustee (or other qualifying trustee) to pay
     and discharge principal of, premium, if any, and interest on the
     outstanding Securities on the Maturity Date or otherwise in accordance with
     the terms of this Indenture and of such Securities; provided that the
     Trustee (or other qualifying trustee) shall have received an irrevocable
     written order from the Company instructing the Trustee (or other qualifying
     trustee) to apply such money or the proceeds of such U.S.  Government
     Obligations to said payments with respect to the Securities;

             (ii)   no Default or Event of Default with respect to the
     Securities or this Indenture shall have occurred and be continuing
     immediately after giving effect to such deposit (or, insofar as Section
     6.1(a)(vii) or (viii) is concerned, at any time during the period ending on
     the 91st day after the date of such deposit (it being understood that this
     condition shall not be deemed satisfied until the expiration of such
     period); provided, however, that actions taken by the Company in connection
     with the creation of the trust fund into which funds for the purpose of
     defeasance of the Securities are deposited that are not in compliance with
     Sections 4.9, 4.13 and 4.14, in each case, shall not be deemed a Default or
     Event of Default under this Indenture);

             (iii)  such legal defeasance or covenant defeasance shall not cause
     the Trustee to have a conflicting interest with respect to any Securities
     of the Company or any Subsidiary Guarantor;

             (iv)   such legal defeasance or covenant defeasance shall not
     result in a breach or violation of, or constitute a Default or Event of
     Default under any agreement or instrument to which the Company or any
     Subsidiary Guarantor is a party or by which it is bound;
<PAGE>
 
                                      -85-

             (v)    in the case of an election under paragraph (b) above, the
     Company shall have delivered to the Trustee an Opinion of Counsel stating
     that (x) the Company has received from, or there has been published by, the
     Internal Revenue Service a ruling or (y) since the date of this Indenture,
     there has been a change in the applicable Federal income tax law, in either
     case to the effect that, and based thereon such opinion shall confirm that,
     the Holders of the outstanding Securities will not recognize income, gain
     or loss for Federal income tax purposes as a result of such legal
     defeasance and will be subject to Federal income tax on the same amounts,
     in the same manner and at the same times as would have been the case if
     such legal defeasance had not occurred;

             (vi)   in the case of an election under paragraph (c) above, the
     Company shall have delivered to the Trustee an Opinion of Counsel to the
     effect that the Holders of the outstanding Securities will not recognize
     income, gain or loss for Federal income tax purposes as a result of such
     covenant defeasance and will be subject to Federal income tax on the same
     amounts, in the same manner and at the same times as would have been the
     case if such covenant defeasance had not occurred;

             (vii)  in the case of an election under either paragraph (b) or (c)
     above, an Opinion of Counsel to the effect that, (x) the trust funds will
     not be subject to any rights of any holders of other Indebtedness,
     including, without limitation, Senior Indebtedness of the Company, and (y)
     after the 91st day following the deposit, the trust funds will not be
     subject to the effect of any applicable Bankruptcy Law; provided that if a
     court were to rule under any such law in any case or proceeding that the
     trust funds remained property of the Company, no opinion needs to be given
     as to the effect of such laws on the trust funds except the following:  (A)
     assuming such trust funds remained in the Trustee's possession prior to
     such court ruling to the extent not paid to Holders of Securities, the
     Trustee will hold, for the benefit of the Holders of Securities, a valid
     and enforceable security interest in such trust funds that is not avoidable
     in bankruptcy or otherwise, subject only to principles of equitable
     subordination, (B) the Holders of Securities will be entitled to receive
     adequate protection of their interests in such trust funds if such trust
     funds are used, and (C) no property, rights in property or other interests
     granted to the Trustee or the Holders of Securities in exchange for or with
     respect to any of such funds will be subject to any prior rights of any
     other person, subject only to prior Liens granted under Section 364 of
     Title 11 of the U.S.  Bankruptcy Code (or any section of any other
     Bankruptcy Law having the same effect), but still subject to the foregoing
     clause (B); and

                                      -86-

             (viii)  the Company shall have delivered to the Trustee an
     Officers' Certificate and an Opinion of Counsel, each stating that (x) all
     conditions precedent provided for relating to either the legal defeasance
     under paragraph (b) above or the covenant defeasance under paragraph (c)
     above, as the case may be, have been complied with and (y) if any other
     Indebtedness of the Company shall then be outstanding or committed, such
     legal defeasance or covenant defeasance will not violate the provisions of
     the agreements or instruments evidencing such Indebtedness.

             (e)    All money and U.S. Government Obligations (including the
proceeds thereof) deposited with the Trustee pursuant to paragraph (d) above in
respect of the outstanding Securities shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent (other
than the Company or any Affiliate of the Company) as the Trustee may determine,
to the Holders of such Securities of all sums due and to become due thereon in
respect of principal, premium and interest, but such money need not be
segregated from other funds except to the extent required by law.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S.  Government Obligations
deposited pursuant to paragraph (d) above or the principal, premium, if any, and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding
Securities.

          Anything in this Section 8.2 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the request,
in writing, by the Company any money or U.S.  Government Obligations held by it
as provided in paragraph (d) above which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount
thereof which would then be required to be deposited to effect an equivalent
legal defeasance or covenant defeasance.

          SECTION 8.3  Application of Trust Money.

          The Trustee shall hold in trust money or U.S. Government Obligations
deposited with it pursuant to Sections 8.1 and 8.2, and shall apply the
deposited money and the money from U.S. Government Obligations in accordance
with this Indenture to the payment of principal of, premium, if any, and
interest on the Securities.

                                      -87-

          SECTION 8.4  Repayment to Company or Subsidiary Guarantors.

          Subject to Sections 7.7, 8.1 and 8.2, the Trustee shall promptly pay
to the Company, or if deposited with the Trustee by any Subsidiary Guarantor, to
such Subsidiary Guarantor, upon receipt by the Trustee of an Officers'
Certificate, any excess money, determined in accordance with Section 8.2, held
by it at any time.  The Trustee and the Paying Agent shall pay to the Company or
any Subsidiary Guarantor, as the case may be, upon receipt by the Trustee or the
Paying Agent, as the case may be, of an Officers' Certificate, any money held by
it for the payment of principal, premium, if any, or interest that remains
unclaimed for two years after payment to the Holders is required (unless
otherwise provided under operation of law); provided that the Trustee and the
Paying Agent before being required to make any payment may, but need not, at the
expense of the Company cause to be published once in a newspaper of general
circulation in The City of New York or mail to each Holder entitled to such
money notice that such money remains unclaimed and that after a date specified
therein, which shall be at least 30 days from the date of such publication or
mailing, any unclaimed balance of such money then remaining will be repaid to
the Company.  After payment to the Company or any Subsidiary Guarantor, as the
case may be, Securityholders entitled to money must look solely to the Company
for payment as general creditors unless an applicable abandoned property law
designates another person, and all liability of the Trustee or Paying Agent with
respect to such money shall thereupon cease.

          SECTION 8.5  Reinstatement.

          If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with this Indenture 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, then
and only then the Company's and each Subsidiary Guarantor's, if any, obligations
under this Indenture and the Securities shall be revived and reinstated as
though no deposit had been made pursuant to this Indenture until such time as
the Trustee is permitted to apply all such money or U.S. Government Obligations
in accordance with this Indenture; provided that if the Company or the
Subsidiary Guarantors, as the case may be, has made any payment of principal of,
premium, if any, or interest on any Securities because of the reinstatement of
its obligations, the Company or the Subsidiary Guarantors, as the case may be,
shall be, subrogated to the rights of the holders of such Securities to receive
such payment from the money or U.S. Government Obligations held by the Trustee
or Paying Agent.

                                   ARTICLE IX


                      AMENDMENTS, SUPPLEMENTS AND WAIVERS

          SECTION 9.1  Without Consent of Holders.

          Without the consent of any Holders, the Company, when authorized by
resolutions of its Board of Directors (copies of which shall be delivered to the
Trustee) and the Trustee may amend, waive or supplement this Indenture or the
Securities without notice to or consent of any Holder for any of the following
purposes:

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

          (b) to provide for uncertificated Securities in addition to or in
     place of certificated Securities;

          (c) to comply with any requirements of the SEC under the TIA;

          (d) to evidence the succession in accordance with Article V hereof of
     another Person to the Company and the assumption by any such successor of
     the covenants of the Company herein and in the Securities;

          (e) to add any Subsidiary of the Company as a Subsidiary Guarantor
     pursuant to the terms of Section 4.15 and Article XII;

          (f) to evidence and provide for the acceptance of appointment
     hereunder by a separate or successor Trustee with respect to the
     Securities; or

          (g) to make any other change that does not adversely affect the rights
     of any Holder;

provided, however, that in making such change, the Trustee may rely upon an
Opinion of Counsel stating that such change does not adversely affect the rights
of any Holder.

          SECTION 9.2  With Consent of Holders.

          Subject to Section 6.7 and the provisions of this Section 9.2, the
Company, when authorized by resolution of its Board of Directors (copies of
which shall be delivered to the Trustee) and the Trustee may amend or supplement
this Indenture, the Securities or any Subsidiary Guarantee with the written
consent of the Holders of at least a majority in 
<PAGE>
 
                                      -89-

principal amount of the Securities then outstanding. Subject to Section 6.7 and
the provisions of this Section 9.2, the Holders of, in the aggregate, at least a
majority in principal amount of the then outstanding Securities affected may
waive compliance by the Company and any Subsidiary Guarantor with any provision
of this Indenture, the Securities or any Subsidiary Guarantee without notice to
any other Securityholder. However, without the consent of each Securityholder
affected, an amendment, supplement or waiver, including a waiver pursuant to
Section 6.4, may not:

          (a)  reduce the aggregate principal amount of Securities the Holders
     of which must consent to an amendment, supplement or waiver of any
     provision of or with respect to this Indenture, the Securities or any
     Subsidiary Guarantee; or

          (b) reduce the rate of, change the method of calculation of, or extend
     the time for, payment of interest, including default interest, on any
     Security; or

          (c) reduce the principal of or premium on or change the Stated
     Maturity of any Security or alter the repurchase provisions with respect
     thereto; or

          (d) make the principal of, or interest on, any Security payable in
     money other than as provided herein, or

          (e) make any change in provisions relating to waivers of defaults, the
     ability of Holders to enforce their rights under this Indenture or in the
     matters discussed in clauses (a) through (h); or

          (f) waive a default in the payment of the principal of, interest on,
     or repurchase payment required hereunder with respect to, any Security,
     including, without limitation, a default to make a payment when required
     upon a Change of Control; or

          (g) adversely affect the ranking of the Securities or any Subsidiary
     Guarantee or release any Subsidiary Guarantor from any of its obligations
     under its Subsidiary Guarantee in this Indenture other than in compliance
     with Section 12.4 of Exhibit B hereto;

          (h) after the Company's obligation to purchase Securities arises
     thereunder, amend, modify or change the obligation of the Company to make
     and consummate a Change of Control Offer in the event of a Change of
     Control or waive any default in the performance thereof or modify any of
     the provisions or definitions with respect to such offers.
<PAGE>
 
                                      -90-

          It shall not be necessary for the consent of the Holders under this
Section 9.2 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 9.2
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.
Notwithstanding the foregoing, no amendment shall modify any provision of this
Indenture so as to affect adversely the rights of any holder of Senior
Indebtedness of the Company or Guarantor Senior Indebtedness to the benefits of
the subordination provisions under this Indenture without the consent of such
holder.

          SECTION 9.3  Compliance with Trust Indenture Act.

          Every amendment to or supplement of this Indenture or the Securities
shall be set forth in a supplemental indenture that complies with the TIA as
then in effect.

          SECTION 9.4  Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder is a continuing consent by the Holder and every subsequent
Holder of that Security or portion of that Security that evidences the same debt
as the consenting Holder's Security, even if notation of the consent is not made
on any Security.  However, any such Holder or subsequent Holder may revoke the
consent as to his Security or portion of a Security.  Such revocation shall be
effective only if the Trustee receives the notice of revocation before the date
the amendment, supplement or waiver becomes effective.  Notwithstanding the
above, nothing in this paragraph shall impair the right of any Securityholder
under (S)316(b) of the TIA.

          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 record date shall be at least 10 days prior to the
first solicitation of such consent.  If a record date is fixed, then
notwithstanding the second and third sentences 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 consent to
such amendment, supplement or waiver or to revoke any consent previously given,
whether or not such Persons continue to be Holders after such record date.  Such
consent shall be effective only for actions taken within 90 days after such
record date.
<PAGE>
 
                                      -91-

          After an amendment, supplement or waiver becomes effective, it shall
bind every Securityholder unless it makes a change described in any of clauses
(a) through (h) of Section 9.2.  In that case the amendment, supplement or
waiver shall bind each Holder of a Security who has consented to it.

          SECTION 9.5  Notation on or Exchange of Securities.

          If an amendment, supplement or waiver changes the terms of a Security,
the Trustee shall (in accordance with the specific written direction of the
Company) request the Holder of the Security to deliver it to the Trustee.  The
Trustee shall (in accordance with the specific direction of the Company) place
an appropriate notation on the Security 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 Security shall issue and the Trustee shall
authenticate a new Security that reflects the changed terms.  Failure to make
the appropriate notation or issue a new Security shall not affect the validity
and effect of such amendment, supplement or waiver.

          SECTION 9.6  Trustee To Sign Amendments, Etc.

          The Trustee shall sign any amendment, supplement or waiver authorized
pursuant to this Article IX if the amendment, supplement or waiver does not
adversely affect the rights, duties or immunities of the Trustee.  If it does,
the Trustee may, but need not, sign it.  In signing any amendment, supplement or
waiver, 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 Officers' Certificate and an Opinion of Counsel stating that
the execution of any amendment, supplement or waiver authorized pursuant to this
Article IX is authorized or permitted by this Indenture and that it constitutes
the legal, valid and binding obligation of the Company and, if applicable, the
Subsidiary Guarantors, subject to the customary exceptions.

                                   ARTICLE X

          SECTION 10.16  Independence of Covenants.

Subsidiary Guarantees shall be given independent effect so that if any
particular action or condition is not permitted by any of such covenants, the
fact that it would be permitted by an exception to, or otherwise be within the
limitations of, another covenant shall not avoid the occurrence of a Default or
an Event of Default if such action is taken or condition exists.

                                  ARTICLE XI


                          SUBORDINATION OF SECURITIES

          SECTION 11.1  Agreement to Subordinate.

          The Company covenants and agrees, and each Holder of Securities, by
his acceptance thereof, likewise covenants and agrees, that the indebtedness
represented by the Securities and the payment of the principal of and interest
on each and all of the Securities is hereby expressly subordinated, to the
extent and in the manner hereinafter set forth, in right of payment to the prior
payment in full of Senior Indebtedness of the Company.

          Anything in the Securities or in this Indenture to the contrary
notwithstanding, the indebtedness evidenced by the Securities shall be
subordinate and junior in right of payment, in all respects, to all Senior
Indebtedness of the Company, whether outstanding at the Issue Date or incurred
after the Issue Date.

          In the event of (i) any insolvency or bankruptcy case or proceeding,
(ii) any receivership, liquidation, dissolution or other winding up of the
Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy or (iii) any assignment for the benefit of the
creditors or any other marshaling of assets and liabilities of the Company, then
and in any such event specified in (i), (ii) or (iii) above, the holders of
Senior Indebtedness shall be entitled to receive payment in full in cash of all
amounts due or to become due on or in respect of all Senior Indebtedness before
the Holders of the Securities are entitled to receive any Note Payment (as
defined below), and in any such event any Note Payment to which the Holders of
the Securities 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, liquidating trustee, agent or other Person
making such payment or distribution, directly to the holders of the Senior
Indebtedness (pro rata to such holders on the basis of the respective amounts of
Senior Indebtedness held by such holders) or their respective trustee, agent or

agreement or indenture pursuant to which any such Senior Indebtedness may have
been issued, as their respective interests may appear, to the extent necessary
to pay all such Senior Indebtedness in full, in cash, after giving effect to any
concurrent payment, distribution or provision therefor to or for the holders of
such Senior Indebtedness.

          In the event that, notwithstanding the foregoing provision prohibiting
such Note Payment, any Note Payment shall be received by the Trustee or any
Holder of Securities at a time when such Note Payment is prohibited as described
in the preceding paragraph and before all obligations in respect of Senior
Indebtedness are paid in full in cash, such Note Payment shall be received and
held in trust for the benefit of, and shall be paid over or delivered to, the
holders of Senior Indebtedness (pro rata to such holders on the basis of the
respective amounts of Senior Indebtedness held by such holders) or their
respective trustee, agent or other representative under any agreement or
indenture pursuant to which any of such Senior Indebtedness may have been
issued, as their respective interests may appear, for application to the payment
of Senior Indebtedness remaining unpaid until all such Senior Indebtedness has
been paid in full in cash after giving effect to any concurrent payment,
distribution or provision therefor to or for the account of the holders of such
Senior Indebtedness.

          No direct or indirect payment, deposit or distribution of any kind or
character, whether in cash, property or securities (including any payment made
to Holders of the Securities under the terms of Indebtedness subordinated to the
Securities, but excluding any payment or distribution of Permitted Junior
Securities) by or on behalf of the Company of principal of, premium, if any, or
interest on, or any other obligation in respect of, the Securities whether
pursuant to the terms of the Securities, upon acceleration, by way of
repurchase, redemption, defeasance or otherwise (all such payments, deposits or
distributions being referred to herein, individually and collectively, as a
"Note Payment"), shall be made if, at the time of such Note Payment, there
exists a default (a "Payment Default") in the payment when due of all or any
portion of the obligations under or in respect of any Designated Senior
Indebtedness, whether at maturity, on account of mandatory redemption or
prepayment, acceleration or otherwise, and such Payment Default shall not have
been cured or waived.  In addition, during the continuance of any default or
event of default (other than a Payment Default) with respect to any Designated
Senior Indebtedness pursuant to which the maturity thereof may be accelerated
immediately without the giving of any notice (except such notice as may be
required to effect such acceleration) or the expiration of any applicable grace
periods, no Note Payment may be made by or on behalf of the Company for a period
(a "Payment Blockage Period") commencing upon the receipt by the Company and the
Trustee of written notice of such default or event of default from the holder or
holders of such Designated Senior Indebtedness or any trustee, agent or other
representative acting on behalf of the holder or holders of such Designated
Senior Indebtedness specifying 
<PAGE>
 
                                      -98-

an election to effect a Payment Blockage Period (a "Payment Blockage Notice")
and ending 179 days thereafter (or earlier if such Payment Blockage Period is
terminated (i) by written notice to the Trustee and the Company from the holder
or holders of such Designated Senior Indebtedness or any trustee, agent or other
representative acting on behalf of the holder or holders of such Designated
Senior Indebtedness, (ii) by discharge or repayment in full in cash of such
Designated Senior Indebtedness or (iii) because the default or event of default
giving rise to such Payment Blockage Notice has been cured, waived or ceased to
exist). Subject to the provisions of the first sentence of this paragraph, the
Company may resume payments on the Securities after such Payment Blockage
Period.

          Not more than one Payment Blockage Period may be commenced with
respect to the Securities during any period of 360 consecutive days, unless at
least 180 consecutive days shall have elapsed during which time no payment
blockage was in effect.  No default or event of default that existed or was
continuing on the date of commencement of any Payment Blockage Period with
respect to the Designated Senior Indebtedness initiating such Payment Blockage
Period 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 Indebtedness
or any trustee, agent or other representative acting on behalf of the holder or
holders of such Designated Senior Indebtedness, whether or not within a period
of 360 consecutive days, unless such default or event of default has been cured
or waived for a period of not less than 90 consecutive days.

          In the event that, notwithstanding the foregoing, any Note Payment
shall be received by the Trustee or any Holder when such Note Payment is
prohibited by the second preceding paragraph, such payment shall be held in
trust for the benefit of, and shall be paid over or delivered to, the holders of
Designated Senior Indebtedness or any trustee, agent or other representative
under any agreement or indenture pursuant to which any such Designated Senior
Indebtedness may have been issued, as their respective interests may appear, but
only to the extent that, upon notice from the Trustee to the holders of
Designated Senior Indebtedness that such prohibited Note Payment has been made,
the holders of the Designated Senior Indebtedness (or their trustee, agent or
other representative) notify the Trustee in writing of the amounts then due and
owing on the Designated Senior Indebtedness, if any, and only the amount
specified in such notice to the Trustee shall be paid to or for the account of
the holders of Designated Senior Indebtedness.

          The failure to make any payment or distribution for or on account of
the Securities by reason of the provisions of this Indenture described under
this section will not be construed as preventing the occurrence of an Event of
Default described in clause (i), (ii) or (iii) of Section 6.1(a).
<PAGE>
 
                                      -99-

          If the Company fails to make any payment on the Securities when due or
within any applicable grace period, whether or not such failure is on account of
the subordination provisions referred to above, such failure would constitute an
Event of Default under this Indenture and would enable the Holders to accelerate
the maturity of the Securities.  See Section 6.1.

          By reason of such subordination, in the event of liquidation or
insolvency, creditors of the Company who are not holders of Senior Indebtedness
of the Company (other than the Holders of the Securities or other equally
subordinated obligations) may recover less, ratably, than the holders of Senior
Indebtedness of the Company and may recover more, ratably, than the Holders of
the Securities.

          The Notes are effectively subordinated to all existing and future
liabilities (including liabilities owed to trade creditors) of the Subsidiaries
of the Company to the extent of the assets of each Subsidiary of the Company.
Any right of the Company to participate in any distribution of the assets of its
Subsidiaries upon the liquidation, reorganization or insolvency thereof (and the
consequent right of the Holders to benefit from those assets) will be subject to
the claims of creditors (including trade creditors) of such Subsidiary, except
to the extent that claims of the Company itself as a creditor of such Subsidiary
may be recognized, in which case the claims of the Company would still be
subordinate to any security interest in the assets of such Subsidiary and any
Indebtedness of such Subsidiary senior to that held by the Company.

          SECTION 11.2  Subrogation.

          Subject to the payment in full of all Senior Indebtedness of the
Company, Holders of the Securities shall be subrogated to the rights of the
holders of Senior Indebtedness of the Company to receive payments or
distributions of cash, property or securities of the Company applicable to the
Senior Indebtedness of the Company until all amounts owing on the Securities
shall be paid in full, and as between the Company, its creditors other than
holders of such Senior Indebtedness, and Holders of the Securities, no such
payment or distribution made to the holders of such Senior Indebtedness by
virtue of this Article XI which otherwise would have been made to the
Securityholders shall be deemed to be a payment by the Company on account of
such Senior Indebtedness, it being understood that the provisions of this
Article XI are and are intended solely for the purpose of defining the relative
rights of the Holders of the Securities, on the one hand, and the holders of
Senior Indebtedness of the Company, on the other hand.

                                     -100-

          SECTION 11.3  Relative Rights.

          Nothing contained in this Article XI or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as between the Company, its
creditors other than the holders of its Senior Indebtedness, and the Holders of
Securities, the obligation of the Company, which is absolute and unconditional,
to pay to the holders of the Securities the principal of and interest on the
Securities 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 Securities and creditors of the Company other than the holders of
its Senior Indebtedness, nor shall anything herein or therein prevent the
Trustee or the Holder of any Security from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the
rights, if any, under this Article XI of the holders of Senior Indebtedness of
the Company to receive cash, property or securities otherwise payable or
deliverable to the Securityholders.

          Upon payment or distribution of assets of the Company referred to in
this Article XI, the Trustee and the Holders of the Securities shall be entitled
to rely upon any order or decree made by any court of competent jurisdiction in
which any such dissolution, winding up, liquidation or reorganization proceeding
affecting the affairs of the Company is pending or upon a certificate of the
trustee in bankruptcy, receiver, assignee for the benefit of creditors,
liquidating trustee, or agent or other person making any payment or
distribution, to the Trustee or to the Holders of the Securities for the purpose
of ascertaining the persons entitled to participate in such payment or
distribution, the holders of the Senior Indebtedness of the Company and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
paid or distributed thereon and all other facts pertinent thereto or to this
Article XI.

          Nothing contained in this Article or elsewhere in this Indenture, or
in any of the Securities, shall affect the obligations of the Company to make,
or prevent the Company from making, payment of the principal of or interest on
the Securities in accordance with the provisions hereof and thereof, except as
otherwise provided in this Article XI.

          SECTION 11.4  Trustee To Effectuate Subordination.

          Each holder of Securities, by his acceptance thereof, authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article XI and
appoints the Trustee his attorney-in-fact for any and all such purposes.

                                     -101-

          SECTION 11.5  Trustee Not Fiduciary for Holders
                        of Senior Indebtedness of the Company.

          The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness of the Company and shall not be liable to any
such holders if it shall mistakenly pay over or distribute to Securityholders or
the Company or any other person moneys or assets to which any holders of Senior
Indebtedness of the Company shall be entitled by virtue of this Article XI or
otherwise.

          SECTION 11.6  Notice by Company.

          The Company shall give prompt written notice to the Trustee of any
fact known to the Company that would prohibit the making of any payment of
moneys to or by the Trustee pursuant to this Article.  Subject to the provisions
of Sections 7.1 and 7.5 but notwithstanding any other provisions of this
Indenture, the Trustee and any Paying Agent shall not be charged with knowledge
of the existence of any facts that would prohibit the making of any payment of
moneys to or by the Trustee or such Paying Agent, or the taking of any other
action by the Trustee or such Paying Agent, unless and until the Trustee or such
Paying Agent shall have received written notice thereof from the Company at
least three Business Days prior to the making of any such payment, the
Securityholders, the holders of any Senior Indebtedness of the Company or the
representative of any such holders.

          SECTION 11.7  Rights of Trustee.

          The Trustee shall be entitled to all the rights set forth in this
Article XI with respect to any Senior Indebtedness of the Company by the time
held by the Trustee, to the same extent as any other holder of Senior
Indebtedness.

          SECTION 11.8  Company May Not Impair Subordination.

          No right of any present or future holder of any Senior Indebtedness of
the Company to enforce the subordination herein shall at any time or in any way
be prejudiced or impaired by any act or failure to act on the part of the
Company or by any noncompliance by the Company with the terms, provisions and
covenants of this Indenture, regardless of any knowledge thereof any such holder
may have or be otherwise charged with.

          SECTION 11.9  Rights of Paying Agent.

          In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context shall require
otherwise) be construed as ex-
<PAGE>
 
                                     -102-

tending to and including such Paying Agent within its meaning as fully for all
intents and purposes as if such Paying Agent were named in this Article XI in
addition to or in place of the Trustee; provided that Sections 11.6 and 11.7
shall not apply to the Company if it acts as Paying Agent.

          This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

          IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first written above.

                     8% SENIOR SUBORDINATED NOTE DUE 2008

          1.  Interest.  NAVISTAR INTERNATIONAL CORPORATION, a Delaware
              --------                                                 
corporation (the "Company," which definition shall include any successor thereto
in accordance with the Indenture (as defined below)), promises to pay, until the
principal hereof is paid or made available for payment, interest on the
principal amount set forth on the reverse side hereof at a rate of 8% per annum.
Interest on the Securities will accrue from and including the most recent date
to which interest has been paid or, if no interest has been paid, from and
including February 4, 1998 through but excluding the date on which interest is
paid.  Interest shall be payable in arrears on February 1, August 1 and at the
stated maturity (each an "Interest Payment Date"), commencing August 1, 1998.
Interest will be computed on the basis of a 360-day year of twelve full 30-day
months and, for periods of less than one month, the actual number of days
elapsed.  Interest on overdue principal and (to the extent permitted by law) on
overdue installments of interest will accrue at a rate equal to 8% per annum.

          2.  Method of Payment.  The Company will pay interest on the
              -----------------                                       
Securities (except defaulted interest) to the Persons who are registered Holders
of Securities at the close of business on the January 15 or July 15 next
preceding the relevant Interest Payment Date.  Holders must surrender Securities
to the Paying Agent to collect principal payments.  The Company will pay
principal, premium, if any, and interest in money of the United States that at
the time of payment is legal tender for payment of public and private debts.  At
the Company's option, interest may be paid by check mailed to the registered
address of the Holder of this Security.

          3.  Paying Agent and Registrar.  Initially, HARRIS TRUST AND SAVINGS
              --------------------------                                      
BANK (the "Trustee") will act as Paying Agent and Registrar.  The Company may
change any Paying Agent, Registrar or co-Registrar without notice.  Neither the
Company nor any of its Subsidiaries may act as Paying Agent, Registrar or co-
Registrar.

          4.  Indenture.  The Company issued the Securities under an Indenture
              ---------                                                       
dated as of February 4, 1998 (the "Indenture") between the Company and the
Trustee.  This Security is one of an issue of Securities of the Company issued
under the Indenture.  The terms of the Securities 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) as amended from time to
time.  The Securities are subject to all such terms, and Securityholders are
referred to the Indenture and such Act for a statement of them.  Capitalized
terms used herein and not otherwise defined have the meanings set forth in the
Indenture.  The Securities are general unsecured obligations of the Company
limited in aggregate principal 

                                      A-2
<PAGE>
 
amount to $250,000,000. The Indenture limits, among other things, the incurrence
of certain Indebtedness by the Company and its Restricted Subsidiaries;
transactions by the Company and its Restricted Subsidiaries with certain
Affiliates; the granting of Liens by the Company or any of its Restricted
Subsidiaries; certain guarantees issued by Restricted Subsidiaries of the
Company and the ability of the Company and the Subsidiary Guarantors to merge
with or into another entity. The limitations are subject to a number of
important qualifications and exceptions. The Company must report to the Trustee
annually whether it is in compliance with the limitations contained in the
Indenture.

          5.  Optional Redemption.  Except as set forth in the next paragraph,
              -------------------                                             
the Securities may not be redeemed prior to February 1, 2003.  On or after
February 1, 2003, the Securities may be redeemed at any time, in whole or in
part, at the option of the Company, on not less than 20 days' nor more than 60
days' notice, at the redemption prices (expressed as percentages of the
principal amount) set forth below, if redeemed during the 12 month period
beginning February 1 of the year indicated below, in each case together with
interest accrued to the redemption date:

<TABLE>
<CAPTION>
          YEAR                                         PERCENTAGE

          2006 and thereafter.......................     100.000%
</TABLE>

          In addition, prior to February 1, 2001, the Company may, at its option
redeem up to 35% of the principal amount of the Securities originally issued
with the net cash proceeds received by the Company from one or more public
offerings of Common Stock of the Company made after the Issue Date, at a
redemption price (expressed as a percentage of the principal amount) of 108% of
the principal amount thereof, plus accrued and unpaid interest to the date fixed
for redemption; provided that at least $162.5 million in aggregate principal
amount of the Securities remains outstanding immediately after any such
redemption (excluding any Notes owned by the Company or any of its Affiliates).
Notice of redemption pursuant to this paragraph must be mailed to Holders of
Senior Subordinated Notes not later than 60 days following the consummation of
such public offering.

          Selection of Securities for any redemption shall be made by the
Trustee under the Indenture in accordance with the rules of any national
securities exchange on which the Securities may be listed or if the Securities
are not so listed, pro rata or by lot or in such other manner as the Trustee
shall deem appropriate and fair.

          On and after the redemption date, interest will cease to accrue on
Securities or portions thereof called for redemption.

                                      A-3
<PAGE>
 
          6.  Notice of Redemption.  Notice of redemption will be mailed by
              --------------------                                         
first-class mail at least 20 days but not more than 60 days before the
redemption date to each Holder of Securities to be redeemed at his registered
address.  Securities in denominations larger than $1,000 may be redeemed in part
but only in whole multiples of $1,000.  If money sufficient to pay the
redemption price of and accrued interest on all Securities (or portions thereof)
to be redeemed on the redemption date is deposited with the Paying Agent on or
before the redemption date and certain other conditions are satisfied, on and
after such date interest ceases to accrue on such Securities (or such portions
thereof) called for redemption.  If a notice or communication is sent in the
manner provided in the Indenture, it is duly given, whether or not the addressee
receives it.  Failure to send a notice or communication to a Securityholder or
any defect in it shall not affect its sufficiency with respect to other
Securityholders.

          7.  Offers to Purchase.  Sections 4.11 and 4.19 of the Indenture
              ------------------                                          
provide upon the occurrence of a Change of Control and after certain Asset
Dispositions, and subject to further limitations contained therein, the Company
shall make an offer to purchase certain amounts of the Securities in accordance
with the procedures set forth in the Indenture.

          8.  Denominations, Transfer, Exchange.  The Securities are in
              ---------------------------------                        
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000.  A Holder may transfer or exchange Securities in accordance
with the Indenture.  The Registrar may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and to pay to it any
taxes and fees required by law or permitted by the Indenture.  The Registrar
need not transfer or exchange any Security or portion of a Security selected for
redemption, or transfer or exchange any Securities for a period of 15 days
before a selection of Securities to be redeemed.

          9.  Persons Deemed Owners.  The registered holder of a Security may be
              ---------------------                                             
treated as the owner of it for all purposes.

          10.  Unclaimed Money.  If money for the payment of principal or
               ---------------                                           
interest remains unclaimed for two years, the Trustee or Paying Agent will pay
the money back to the Company at its request.  After that, Holders entitled to
the money must look to the Company for payment as general creditors unless an
"abandoned property" law designates another Person.

          11.  Amendment, Supplement, Waiver.  The Company and the Trustee may,
               -----------------------------                                   
without the consent of the holders of any outstanding Securities, amend, waive
or supplement the Indenture, the Securities or Subsidiary Guarantee for certain
specified purposes, including, among other things, curing ambiguities, defects
or inconsistencies, maintaining the qualification of the Indenture under the
Trust Indenture Act of 1939 or making any 

                                      A-4
<PAGE>
 
other change that does not adversely affect the rights of any Holder. Other
amendments and modifications of the Indenture, the Securities or any Subsidiary
Guarantee may be made by the Company and the Trustee with the consent of the
Holders of not less than a majority of the aggregate principal amount of the
outstanding Securities, subject to certain exceptions requiring the consent of
the Holders of the particular Securities to be affected.

          12.  Guarantees.  This Security may after the date hereof be entitled
               ----------                                                      
to certain Subsidiary Guarantees made for the benefit of the Holders.  Reference
is hereby made to Section 4.15 of the Indenture and to Exhibit B to the
Indenture for the terms of any Subsidiary Guarantee (including any terms of
subordination of such Subsidiary Guarantee that may apply).

          13.  Successor Corporation.  When a successor corporation assumes all
               ---------------------                                           
the obligations of its predecessor under the Securities and the Indenture and
the transaction complies with the terms of Article V of the Indenture, the
predecessor corporation, subject to certain exceptions, will be released from
those obligations.

          14.  Defaults and Remedies.  Events of Default are set forth in the
               ---------------------                                         
Indenture.  Subject to certain limitations in the Indenture, if an Event of
Default (other than an Event of Default specified in Section 6.1(a)(vii) or
(viii) of the Indenture with respect to the Company) occurs and is continuing,
then the holders of not less than 25% in aggregate principal amount of the
outstanding Securities may, or the Trustee may, declare the principal of,
premium, if any, plus accrued interest, if any, to be due and payable
immediately.  If an Event of Default specified in Section 6.1(a)(vii) or (viii)
of the Indenture with respect to the Company occurs and is continuing, the
principal of, premium, if any, and accrued interest on all of the Securities
shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder.
Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture.  The Trustee may require indemnity reasonably
satisfactory to it before it enforces the Indenture or the Securities.  Subject
to certain limitations, Holders of a majority in principal amount of the then
outstanding Securities may direct the Trustee in its exercise of any trust or
power.  The Trustee may withhold from Securityholders notice of any continuing
default (except a default in payment of principal or interest or a failure to
comply with Article V of the Indenture) if it determines that withholding notice
is in their interests.  The Company must furnish an annual compliance
certificate to the Trustee.

          15.  Trustee Dealings with Company.  The Trustee, in its individual or
               -----------------------------                                    
any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not Trustee.

          16.  No Recourse Against Others.  A Trustee, director, officer,
               --------------------------                                
employee, stockholder or beneficiary, as such, of the Company or any Subsidiary
Guarantor shall not have any liability for any obligations of the Company or any
Subsidiary Guarantor under the Securities, the Indenture or any Subsidiary
Guarantee or for any claim based on, in respect of or by reason of, such
obligations or their creation.  Each Securityholder by accepting a Security
waives and releases all such liability.  The waiver and release are part of the
consideration for the issue of the Securities.

          17.  Defeasance.  The Indenture contains provisions (which provisions
               ----------                                                      
apply to this Security) for defeasance at any time of (a) the entire
indebtedness of the Company and any Subsidiary Guarantor or this Security and
(b) certain restrictive covenants and related Defaults and Events of Default, in
each case upon compliance by the Company with certain conditions set forth
therein.

          18.  Authentication.  This Security shall not be valid until the
               --------------                                             
Trustee signs the certificate of authentication on the other side of this
Security.

          19.  Abbreviations.  Customary abbreviations may be used in the name
               -------------                                                  
of a Securityholder or an assignee, such as:  TEN COM (= tenants in common),
TENANT (= tenants by the entireties), JT TEN (= joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (=
Uniform Gifts to Minors Act).

          20.  Subordination.  The Company's payment of principal of, premium,
               -------------                                                  
if any, and interest on the Securities is subordinated in right of payment, to
the extent and in the manner provided in Article XI of the Indenture, to the
prior payment in full of the Senior Indebtedness of the Company.  Each Holder of
the Securities, by his acceptance hereof, covenants and agrees that all payments
of the principal of, premium, if any, and interest on the Securities by the
Company shall be subordinated in accordance with the provisions of Article XI of
the Indenture, and each Holder accepts and agrees to be bound by such
provisions.

          21.  GOVERNING LAW.  THE INDENTURE, THIS SECURITY AND EACH SUBSIDIARY
               -------------                                                   
GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE

                                  ARTICLE XII


                            GUARANTEE OF SECURITIES

          SECTION 12.1  Subsidiary Guarantee.
                        -------------------- 

          Subject to the provisions of this Article XII, each Subsidiary
Guarantor hereby jointly and severally unconditionally guarantees to each Holder
of a Security authenticated and delivered by the Trustee and to the Trustee and
its successors and assigns, irrespective of the validity and enforceability of
this Indenture, the Securities or the obligations of the Company or any other
Subsidiary Guarantors to the Holders or the Trustee hereunder or thereunder,
that:  (a) the principal of, premium, if any, and interest on the Securities
will be duly and punctually paid in full when due, whether at maturity, by
acceleration or otherwise, and interest on the overdue principal and (to the
extent permitted by law) interest, if any, on the Securities and all other
obligations of the Company or the Subsidiary Guarantors to the Holders or the
Trustee hereunder or thereunder (including fees or expenses) and all other
obligations with respect to the Securities and this Indenture will be promptly
paid in full or performed, all in accordance with the terms hereof and thereof;
and (b) in case of any extension of time of payment or renewal of any
Securities, the same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at Stated
Maturity, by acceleration or otherwise.  Failing payment when due of any amount
so guaranteed, or failing performance of any other obligation of the Company to
the Holders, for whatever reason, each Subsidiary Guarantor will be obligated to
pay, or to perform or cause the performance of, the same immediately.  An Event
of Default under this Indenture or the Securities shall constitute an event of
default under this Subsidiary Guarantee, and shall entitle the Holders of
Securities to accelerate the obligations of the Subsidiary Guarantors hereunder
in the same manner and to the same extent as the obligations of the Company.

          Each of the Subsidiary Guarantors hereby agrees that its obligations
hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Securities or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any holder of the Securities with
respect to any provisions hereof or thereof, any release of any other Subsidiary
Guarantor, the recovery of any judgment against the Company, any action to
enforce the same, whether or not a Subsidiary Guarantee is affixed to any
particular Security, or any other circumstance which might otherwise constitute
a legal or equitable discharge or defense of a guarantor.  Each of the
Subsidiary Guarantors hereby waives the benefit of 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 cove-

                                      B-1
<PAGE>
 
nants that its Subsidiary Guarantee will not be discharged except by complete
performance of the obligations contained in the Securities, this Indenture and
this Subsidiary Guarantee. If any Holder or the Trustee is required by any court
or otherwise to return to the Company or to any Subsidiary Guarantor, or any
custodian, trustee, liquidator or other similar official acting in relation to
the Company or such Subsidiary Guarantor, any amount paid by the Company or such
Subsidiary Guarantor to the Trustee or such Holder, this Subsidiary Guarantee,
to the extent theretofore discharged, shall be reinstated in full force and
effect. Each Subsidiary Guarantor further agrees that, as between it, on the one
hand, and the Holders of Securities and the Trustee, on the other hand, (a)
subject to this Article XII, the maturity of the obligations guaranteed hereby
may be accelerated as provided in Article VI hereof for the purposes of this
Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby,
and (b) in the event of any acceleration of such obligations as provided in
Article VI hereof, such obligations (whether or not due and payable) shall
forthwith become due and payable by the Subsidiary Guarantors for the purpose of
this Subsidiary Guarantee.

          This Subsidiary Guarantee shall remain in full force and effect and
continue to be effective should any petition be filed by or against the Company
for liquidation or reorganization, should the Company become insolvent or make
an assignment for the benefit of creditors or should a receiver or trustee be
appointed for all or any significant part of the Company's assets, and shall, to
the fullest extent permitted by law, continue to be effective or be reinstated,
as the case may be, if at any time payment and performance of the Securities
are, pursuant to applicable law, rescinded or reduced in amount, or must
otherwise be restored or returned by any obligee on the Securities, whether as a
"voidable preference," "fraudulent transfer" or otherwise, all as though such
payment or performance had not been made.  In the event that any payment, or any
part thereof, is rescinded, reduced, restored or returned, the Securities shall,
to the fullest extent permitted by law, be reinstated and deemed reduced only by
such amount paid and not so rescinded, reduced, restored or returned.

          No stockholder, officer, director, employer or incorporator, past,
present or future, or any Subsidiary Guarantor, as such, shall have any personal
liability under this Subsidiary Guarantee by reason of his, her or its status as
such stockholder, officer, director, employer or incorporator.

          The Subsidiary Guarantors shall have the right to seek contribution
from any non-paying Subsidiary Guarantor so long as the exercise of such right
does not impair the rights of the Holders under this Subsidiary Guarantee.

          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 each Subsidiary Guarantor pursuant to its Subsidiary Guarantee not constitute
a fraudulent transfer 

                                      B-2
<PAGE>
 
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 each
Subsidiary Guarantor hereby irrevocably agrees that the obligations of each
Subsidiary Guarantor under the Subsidiary Guarantees shall be limited to the
maximum amount as will, after giving effect to all other contingent and fixed
liabilities of each Subsidiary Guarantor (including, but not limited to, the
Guarantor Senior Indebtedness of each Subsidiary Guarantor) result in the
obligations of each Subsidiary Guarantor under the Subsidiary Guarantees not
constituting such fraudulent transfer or conveyance.

          SECTION 12.2  Execution and Delivery of Subsidiary Guarantee.
                                                             ----------

          To further evidence the Subsidiary Guarantee set forth in Section
12.1, each Subsidiary Guarantor hereby agrees that a notation of such Subsidiary
Guarantee, substantially in the form included in Exhibit C hereto, shall be
endorsed on each Security authenticated and delivered by the Trustee after such
Subsidiary Guarantee is executed and executed by either manual or facsimile
signature of an Officer of each Subsidiary Guarantor.  The validity and
enforceability of any Subsidiary Guarantee shall not be affected by the fact
that it is not affixed to any particular Security.

          Each of the Subsidiary Guarantors hereby agrees that its Subsidiary
Guarantee set forth in Section 12.1 shall remain in full force and effect
notwithstanding any failure to endorse on each Security a notation of such
Subsidiary Guarantee.

          If an Officer of a Subsidiary Guarantor whose signature is on this
Indenture or a Security no longer holds that office at the time the Trustee
authenticates such Security or at any time thereafter, such Subsidiary
Guarantor's Subsidiary Guarantee of such Security shall be valid nevertheless.

          The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Subsidiary Guarantee set
forth in this Indenture on behalf of the Subsidiary Guarantor.

          SECTION 12.3  Additional Subsidiary Guarantors.
                        -------------------------------- 

          Any person may become a Subsidiary Guarantor by executing and
delivering to the Trustee (a) a supplemental indenture in form and substance
satisfactory to the Trustee, which subjects such person to the provisions of
this Indenture as a Subsidiary Guarantor, and (b) an Opinion of Counsel to the
effect that such supplemental indenture has been duly authorized and executed by
such person and constitutes the legal, valid, binding and enforceable obligation
of such person (subject to such customary exceptions concerning fraudulent
conveyance laws, creditors' rights and equitable principles as may be acceptable
to the Trustee in its discretion).

<PAGE>
 
          SECTION 12.4  Release of a Subsidiary Guarantor.
                        --------------------------------- 

          (a)  In the event that each other holder of Indebtedness of the
Company or of any of the Company's Subsidiaries of which a Subsidiary Guarantor
has guaranteed the payment thereof unconditionally releases a Subsidiary
Guarantor of all of its obligations under such guarantee pursuant to a written
agreement in form and substance satisfactory to the Trustee (other than a
release resulting from payment under such guarantee) such Subsidiary Guarantor
shall be automatically and unconditionally released from all obligations under
its Subsidiary Guarantee; provided that a release of a Subsidiary Guarantor may
only be obtained under the circumstances described in this sentence if an
Officers' Certificate to that effect has been delivered to the Trustee.

          (b) In addition, except in the case where the prohibition on transfer
in Section 5.1 is applicable, upon the sale or disposition of all (but not less
than all) of the Capital Stock of a Subsidiary Guarantor by the Company or a
Subsidiary of the Company, or upon the consolidation or merger of a Subsidiary
Guarantor with or into any Person (in each case, other than to the Company or an
Affiliate of the Company), such Subsidiary Guarantor shall be deemed
automatically and unconditionally released and discharged from all obligations
under this Article XII without any further action required on the part of the
Trustee or any Holder; provided that each such Subsidiary Guarantor is sold or
disposed of in accordance with Article V.

          (c) The Trustee shall deliver an appropriate instrument evidencing the
release of a Subsidiary Guarantor upon receipt of a request of the Company
accompanied by an Officers' Certificate certifying as to the compliance with
this Section 12.4.  Any Subsidiary Guarantor not so released or the entity
surviving such Subsidiary Guarantor, as applicable, will remain or be liable
under its Subsidiary Guarantee as provided in this Article XII.

          The Trustee shall execute any documents reasonably requested by the
Company or a Subsidiary Guarantor in order to evidence the release of such
Subsidiary Guarantor from its obligations under its Subsidiary Guarantee
endorsed on the Securities and under this Article XII.

          Except as set forth in Articles IV and V and this Section 12.4,
nothing contained in this Indenture or in any of the Securities 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
property of a Subsidiary Guarantor as an entirety or substantially as an
entirety to the Company or another Subsidiary Guarantor.

          SECTION 12.5  Waiver of Subrogation.
                        --------------------- 

          Each Guarantor hereby irrevocably waives any claim or other rights
which it may now or hereafter acquire against the Company or any of its
Subsidiaries that arise from the existence, payment, performance or enforcement
of such Subsidiary Guarantor's obligations under this Subsidiary 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 Securities against the Company or any of its
Subsidiaries, 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 or any of its Subsidiaries, 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 Securities 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 Securities, and shall,
subject to the subordination provisions of this Article and to Article XI,
forthwith be paid to the Trustee for the benefit of such Holders to be credited
and applied upon the Securities, 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
12.5 is knowingly made in contemplation of such benefits.

          SECTION 12.6  Agreement to Subordinate.
                        ------------------------ 

          Each Subsidiary Guarantor covenants and agrees, and each Holder of
Securities, by his acceptance thereof, likewise covenants and agrees, that the
indebtedness represented by such Subsidiary Guarantor's Subsidiary Guarantee and
the payment of the principal of and interest on each and all of the Securities
pursuant to such Subsidiary Guarantor's Subsidiary Guarantee is hereby expressly
subordinated, to the extent and in the manner hereinafter set forth, in right of
payment to the prior payment in full of Guarantor Senior Indebtedness.

          Anything in the Subsidiary Guarantee, the Securities or in this
Indenture to the contrary notwithstanding, the indebtedness evidenced by such
Subsidiary Guarantor's Subsidiary Guarantee shall be subordinate and junior in
right of payment, in all respects, to all Guarantor Senior Indebtedness of such
Subsidiary Guarantor, whether outstanding at the Issue Date or incurred after
the Issue Date.  Without limiting the effect of the foregoing, "subordinate" and
"junior" as used herein shall include within their meanings the following:

             (i) in the event of any insolvency or bankruptcy proceedings, and
     any receivership, liquidation, reorganization or other similar proceedings
     in connection therewith, relative to the Subsidiary Guarantor or its
     creditors or its property, and in 

                                      B-5
<PAGE>
 
     the event of any proceedings for voluntary liquidation, dissolution or
     other winding up of the Subsidiary Guarantor, whether or not involving
     insolvency or bankruptcy proceedings, then (A) all Guarantor Senior
     Indebtedness of such Subsidiary Guarantor shall first be paid in full, or
     such payment be provided for, before any payment on account of principal or
     interest is made upon the Indebtedness evidenced by the Subsidiary
     Guarantee of such Subsidiary Guarantor, and (B) in any such proceedings any
     payment or distribution of any kind or character (including without
     limitation any distribution realized from or attributable to any security
     interest of the Holders of the Securities in property or assets of such
     Subsidiary Guarantor), whether in cash or property or securities which may
     be payable or deliverable in respect of the Subsidiary Guarantee of such
     Subsidiary Guarantor, shall be paid or delivered directly to the holders of
     such Guarantor Senior Indebtedness of such Subsidiary Guarantor (or the
     representative or representatives of such holders or the trustee or
     trustees under any indenture under which any instruments evidencing any of
     such Guarantor Senior Indebtedness of such Subsidiary Guarantor shall have
     been issued) for application in payment thereof, unless and until such
     Guarantor Senior Indebtedness of such Subsidiary Guarantor shall have been
     paid in full or such payment shall have been provided for; provided that
     (1) in the event that payment or delivery of such cash, property or
     securities to the Holders of the Securities is authorized by an order or
     decree giving effect, and stating in such order or decree that effect is
     given, to the subordination of the Subsidiary Guarantee of such Subsidiary
     Guarantor to Guarantor Senior Indebtedness of such Subsidiary Guarantor,
     and made by a court of competent jurisdiction in a reorganization
     proceeding under any applicable law, no payment or delivery of such cash,
     property or securities payable or deliverable with respect to the
     Securities need be made to the holders of Guarantor Senior Indebtedness of
     such Subsidiary Guarantor, (2) no such delivery need be made of securities
     which are issued pursuant to voluntary reorganization, dissolution, or
     liquidation proceedings by such Subsidiary Guarantor or by such Subsidiary
     Guarantor as reorganized, if such securities are subordinate and junior to
     the payment of all Guarantor Senior Indebtedness of such Subsidiary
     Guarantor then outstanding to the same extent as the Subsidiary Guarantee
     of such Subsidiary Guarantor and (3) if, pursuant to the foregoing, a
     payment or delivery of cash, property or securities is to be made to the
     holders of Guarantor Senior Indebtedness of such Subsidiary Guarantor (or

          The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Guarantor Senior Indebtedness and shall not be liable to any such

which any holders of Guarantor Senior Indebtedness shall be entitled by virtue
of this Article XII or otherwise.

          SECTION 12.11  Notice By Subsidiary Guarantor.

<PAGE>
 
ment of moneys to or by the Trustee pursuant to this Article. Subject to the
provisions of Sections 7.1 and 7.5 but notwithstanding any other provisions of

knowledge of the existence of any facts that would prohibit the making of any
payment of moneys to or by the Trustee or such Paying Agent, or the taking of
any other action by the Trustee or such Paying Agent, unless and until the
Trustee or such Paying Agent shall have received written notice thereof from

                         Impair Subordination.

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

          SECTION 12.14  Rights of Paying Agent.
                         ---------------------- 

          In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context shall require
otherwise) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article XII in addition to or in place of the Trustee; provided
that Sections 12.11 and 12.12 shall not apply to such Subsidiary Guarantor if it
acts as Paying Agent.

Ladies and Gentlemen:

     Navistar International Corporation, a Delaware corporation (the "Company"),
proposes to issue and sell to J.P. Morgan Securities Inc., Credit Suisse First
Boston Corporation and Chase Securities Inc. (the "Initial Purchasers")
$100,000,000 aggregate principal amount of its 7% Senior Notes due 2003 (the
"Securities"). The Securities will be issued pursuant to the provisions of an
Indenture to be dated as of February 4, 1998 (the "Indenture") by and between
the Company and Harris Trust and Savings Bank as Trustee (the "Trustee").

     The sale of the Securities to the Initial Purchasers will be made without
registration of the Securities under the Securities Act of 1933, as amended, and
the rules and regulations thereunder (collectively, the "Securities Act"), in
reliance upon the exemption therefrom provided by Section 4(2) of the Securities
Act. Holders of the Securities will have the benefits of a Registration Rights
Agreement to be dated as of February 4, 1998 among the Company and the Initial
Purchasers (the "Registration Rights Agreement").

     The Company hereby agrees with the Initial Purchasers as follows:

     1.  The Company hereby agrees, upon the basis of your representations and
warranties contained in Section 2 hereof, to issue and sell the Securities to
the several Initial 
<PAGE>
 
                                      -2-

Purchasers as hereinafter provided, and each Initial Purchaser, upon the basis
of the representations and warranties herein contained, but subject to the
conditions hereinafter stated, agrees to purchase, severally and not jointly,
from the Company the respective principal amount of Securities set forth
opposite such Initial Purchaser's name in Schedule I hereto at a price equal to
98.5429% of their principal amount (the "Purchase Price") plus accrued interest,
if any, from February 4, 1998.

     2.  The Company understands that the Initial Purchasers intend (x) to offer
privately the Securities as soon after this Agreement has become effective as in
the judgment of the Initial Purchasers is advisable and (y) initially to offer
the Securities upon the terms set forth in the Offering Memorandum (as defined
below).

     The Company confirms that it has authorized the Initial Purchasers, subject
to the restrictions set forth below, to distribute copies of the Offering
Memorandum in connection with the offering of the Securities.  Each Initial
Purchaser hereby makes to the Company the following representations, warranties
and covenants:

          (i)    it is a qualified institutional buyer within the meaning of
     Rule 144A under the Securities Act; and

          (ii)   (A) it will not solicit offers for, or offer to sell, the
     Securities by any form of general solicitation or general advertising (as
     those terms are used in Regulation D under the Securities Act) and (B) it
     will solicit offers for the Securities only from, and will offer the
     Securities only to, (1) persons whom it reasonably believes to be
     "qualified institutional buyers" within the meaning of Rule 144A under the
     Securities Act or (2) upon the terms and conditions set forth in Annex I to
     this Agreement.

     3.   Payment for the Securities shall be made to the Company by wire
transfer in immediately available funds, to the account specified by the Company
to the Initial Purchasers at a bank reasonably acceptable to the Initial
Purchasers no later than noon the Business Day (as defined below) prior to the
Closing Date (as defined below), on February 4, 1998 or at such other time on
the same or such other date, not later than the fifth Business Day thereafter,
as the Initial Purchasers and the Company may agree upon in writing. The time
and date of such payment for the Securities are referred to herein as the
"Closing Date." As used herein, the term "Business Day" means any day other than
a day on which banks are permitted or required to be closed in New York City.

     Payment for the Securities shall be made against delivery to the nominee of
The Depository Trust Company for the account of the Initial Purchasers of one or
more global notes representing such Securities (collectively, the "Global
Notes"), with any transfer taxes

Securities duly paid by the Company. The Global Notes will be made available for
inspection by the Initial Purchasers at the office of J.P. Morgan Securities
Inc. at the address set forth above not later than 1:00 P.M., New York City

     provided that in no event shall the Company be obligated to qualify to do
     business in any jurisdiction where it is not now so qualified or to take

     Securities Act (or any successor thereto);

          (n)  not to take any action prohibited by Regulation M under the
     Exchange Act (or any successor provision), in connection with the

     if made on and as of the Closing Date and the Company shall have complied,
     in all material respects, 
<PAGE>
 
                                      -12-

     with all agreements and all conditions on its part to be performed or
     satisfied hereunder at or prior to the Closing Date;

          (b)  subsequent to the execution and delivery of this Agreement and
     prior to the Closing Date, there shall not have occurred any downgrading,
     nor shall any notice have been given of (i) any intended or potential
     downgrading or (ii) any review or possible change that does not indicate an
     improvement, in the rating accorded any securities of or guaranteed by the
     Company by any "nationally recognized statistical rating organization," as
     such term is defined for purposes of Rule 436(g)(2) under the Securities
     Act;

          (c)  since the respective dates as of which information is given in
     the Offering Memorandum there shall not have been any Material Adverse
     Change, otherwise than as set forth in the Offering Memorandum, the effect
     of which in the sole judgment of the Initial Purchasers makes it
     impracticable or inadvisable to proceed with the offering or the delivery
     of the Securities on the terms and in the manner contemplated in the
     Offering Memorandum;

          (d)  the Initial Purchasers shall have received on and as of the
     Closing Date a certificate, addressed to the Initial Purchasers and dated
     the Closing Date, of an executive officer of the Company satisfactory to
     the Initial Purchasers to the effect set forth in subsections (a) through
     (c) of this Section and to the further effect that since the respective
     dates as of which information is given in the Offering Memorandum there has
     not occurred any Material Adverse Change, otherwise than as set forth in
     the Offering Memorandum, provided that the officer making such certificate
     may rely upon his knowledge as to pending or threatened proceedings;

          (e)  the Initial Purchasers shall have received on the Closing Date a
     signed opinion of Kirkland & Ellis, special counsel for the Company, in

     Initial Purchasers, dated the Closing Date and addressed to the Initial
     Purchasers, to the effect as set forth in Annex III hereto.

          (f)  the Initial Purchasers shall have received on the Closing Date a
     signed opinion of Robert Boardman, General Counsel of the Company, in form
     and substance satisfactory to Cahill Gordon & Reindel, counsel to the
     Initial Purchasers, dated the Closing Date and addressed to the Initial

          existing as a corporation in good standing under the laws of the State
          of Delaware with full power and authority (corporate and other) to
          own, lease and operate
<PAGE>
 
                                      -13-

          its properties and to conduct its business as described in the

               (ii)   the Company has been duly qualified as a foreign
          corporation for the transaction of business and is in good standing in
          each jurisdiction in which it owns or leases properties, or conducts
          business, so as to require such qualification, except where the
          failure to be in good standing would not reasonably be expected to
          have a Material Adverse Effect;

               (iii)  each Subsidiary has been duly incorporated and is validly
          existing as a corporation under the laws of its jurisdiction of
          incorporation with power and authority (corporate and other) to own,
          lease and operate its properties and to conduct its business, and has
          been duly qualified as a foreign corporation for the transaction of
          business and is in good standing in each jurisdiction in which it owns
          or leases properties, or conducts business, so as to require such
          qualification, except where the failure to be in good standing would
          not reasonably be expected to have a Material Adverse Effect;

               (iv)   the authorized capital stock of the Company is as set
          forth in the Offering Memorandum;

               (v)    all the outstanding shares of capital stock of each

          paid and non-assessable, and, except as otherwise set forth in the
          Offering Memorandum, are directly or indirectly owned by the Company
          free and clear of any mortgage, pledge, security interest, lien, claim
          or other encumbrance or restriction on transferability or voting
          (other than as may be imposed by the Securities Act and the various
          state securities laws);

               (vi)   all of the outstanding shares of capital stock of the
          Company have been duly authorized and validly issued and are fully
          paid and non-assessable;

               (vii)  except as described in the Offering Memorandum, there is
          no action, suit or proceeding before or by any government,
          governmental instrumentality, agency, body or court, domestic or
          foreign, now pending or, to the best knowledge of such counsel after
          reasonable investigation, threatened against or affecting the Company
          or any of the Subsidiaries that could reasonably be expected to have a
          Material Adverse Effect or that could reasonably be expected to have a
          material adverse effect on the consummation of the transactions
          contemplated in, or the fulfillment of the terms of, this 
<PAGE>
 
                                      -14-

          Agreement, the Offering Memorandum, the Indenture or the Registration
          Rights Agreement; there is no action, suit or proceeding before or by
          any government, governmental instrumentality, agency, body or court,
          now pending, or to the best knowledge of such counsel after reasonable
          investigation, threatened against or affecting the Company or any
          Subsidiary that would be required to be described in a registration
          statement filed pursuant to the Securities Act that is not described
          in the Offering Memorandum; and

               (viii) the execution and delivery by the Company of, and the
          performance by the Company of all of the provisions of its obligations
          under, this Agreement, the Indenture, the Registration Rights
          Agreement, the Securities, and the consummation by the Company of the
          transactions contemplated therein and in the Offering Memorandum, do
          not and will not conflict with, or result in a breach or violation of
          any of the terms or provisions of, or constitute a default (or an
          event which, with notice or lapse of time, or both, would constitute a
          default) under, or give rise to any right to accelerate the maturity
          or require the prepayment of any indebtedness or the purchase of any
          capital stock under, or result in the creation or imposition of any
          lien, charge or encumbrance upon any material properties or assets of
          the Company or of any Subsidiary under, (A) any material contract,
          indenture, mortgage, deed of trust, loan agreement note, lease,
          partnership agreement or other agreement or instrument known to such
          counsel after reasonable investigation to which the Company or any
          Subsidiary is a party or by which any of them may be bound or to which
          any of their respective properties or assets may be subject or (B) any
          judgment, order or decree of any government, governmental
          instrumentality, agency, body or court, domestic or foreign, having
          jurisdiction over the Company or any Subsidiary or any of their
          respective properties or assets known to such counsel after reasonable
          investigation except, with respect to clauses (A) and (B), any breach
          or violation that would not reasonably be expected to have a Material
          Adverse Effect.

     Such counsel shall also advise, based on its participation in the
preparation of the Offering Memorandum and conferences with officers and
representatives of the Company, representatives of the independent public
accountants for the Company, representatives of the Initial Purchasers and
counsel to the Initial Purchasers, that nothing has come to its attention that
leads it to believe that the Offering Memorandum (as supplemented, if
applicable) (other than the financial statements, supporting schedules and other
financial and statistical data set forth therein, as to which no advice need be
given), as of its date or as of the Closing Date, contained or contains an
untrue statement of a material fact or omitted or 
<PAGE>
 
                                      -15-

omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

          (g)  on the date of the issuance of the Offering Memorandum and also
     on the Closing Date, Deloitte & Touche shall have furnished to the Initial
     Purchasers letters, dated the respective dates of delivery thereof, in form
     and substance satisfactory to the Initial Purchasers, containing statements
     and information of the type customarily included in accountants' "comfort
     letters" to underwriters with respect to the financial statements and
     certain financial information relating to the Company contained in the
     Offering Memorandum;

          (h)  the Company shall have executed and delivered the Registration
     Rights Agreement substantially in the form attached hereto as Annex II;

          (i)  the Initial Purchasers shall have received on and as of the
     Closing Date an opinion of Cahill Gordon & Reindel, counsel to the Initial
     Purchasers, with respect to the validity of the Indenture and the
     Securities, and such other related matters as the Initial Purchasers may
     reasonably request, and such counsel shall have received such papers and
     information as they may reasonably request to enable them to pass upon such
     matters;

          (j)  the Initial Purchasers shall have received on and as of the
     Closing Date a certificate dated the Closing Date and addressed to the
     Initial Purchasers signed by the Executive Vice President - Chief Financial
     Officer, Vice President and Treasurer of the Company or the Vice President
     and Controller to the effect that neither the Company nor any of its
     Subsidiaries is in breach or violation of any of the terms or provisions
     of, or with the giving of notice or lapse of time, or both, would be in
     default under any contract, indenture, mortgage, deed of trust, loan
     agreement, note, lease, partnership agreement, or other agreement or
     instrument to which the Company or any Subsidiary is a party or by which
     any of them may be bound or to which any of their respective properties or
     assets may be subject, except for any such breach or violation which would
     not have a Material Adverse Effect;

          (k)  on or prior to the Closing Date the Company shall have furnished
     to the Initial Purchasers such further certificates and documents as the
     Initial Purchasers or their counsel, Cahill Gordon & Reindel, shall
     reasonably request; and

          (l)  on or prior to the Closing Date the Company shall have furnished
     to the Initial Purchasers a duly executed waiver and amendment to the
     Mexico Credit Agreement (as defined in the Offering Memorandum) in form and
     substance satisfactory to them.
<PAGE>
 
                                      -16-

     7.   The Company agrees to indemnify and hold harmless each Initial
Purchaser, its officers and directors, and each person, if any, who controls any
Initial Purchaser within the meaning of either Section 15 of the Securities Act
or Section 20 of the Exchange Act, from and against any and all losses, claims,
damages and liabilities (including, without limitation, the reasonable legal
fees and other expenses incurred in connection with any suit, action or
proceeding or any claim asserted) caused by any untrue statement or alleged
untrue statement of a material fact contained in the Offering Memorandum (as
amended or supplemented if the Company shall have furnished any amendments or
supplements thereto) or any preliminary offering memorandum or caused by any
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 except insofar as such
losses, claims, damages or liabilities are caused by any untrue statement or
omission or alleged untrue statement or omission (i) made in reliance upon and
in conformity with information relating to the Initial Purchasers furnished to
the Company in writing by the Initial Purchasers expressly for use therein or
(ii) contained in the Preliminary Offering Memorandum if any Initial Purchaser
failed to send or deliver a copy of the Offering Memorandum to a U.S. person (as
defined in Regulation S) and who asserts such losses, claims, damages or
liabilities on or prior to the delivery of written confirmation of sale of the
Securities to such person and such Offering Memorandum would have corrected such
untrue statement or omission and it shall have been determined that such losses,
claims, damages or liabilities would not have arisen had the Offering Memorandum
been delivered or sent.

     Each Initial Purchaser agrees, severally and not jointly, to indemnify and
hold harmless the Company, its directors and officers and each person who
controls the Company within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act to the same extent as the foregoing indemnity
from the Company to each Initial Purchaser, but only with reference to
information relating to such Initial Purchaser furnished to the Company in
writing by such Initial Purchaser expressly for use in the Offering Memorandum,
any amendment or supplement thereto, or any preliminary offering memorandum.
For purposes of this Section 7 and paragraphs (a) and (b) of Section 4 hereof,
the only written information furnished by the Initial Purchasers to the Company
expressly for use in the Offering Memorandum is the information in the last
paragraph of the cover page of the Offering Memorandum, the fourth paragraph on
page 2 of the Offering Memorandum and the first, third, fifth, eighth and ninth
paragraphs under the caption in the "Plan of Distribution" section of the
Offering Memorandum.

     If any suit, action, proceeding (including any governmental or regulatory
investigation), claim or demand shall be brought or asserted against any person
in respect of which indemnity may be sought pursuant to either of the two
preceding paragraphs, such person 
<PAGE>
 
                                      -17-

(the "Indemnified Person") shall promptly notify the person against whom such
indemnity may be sought (the "Indemnifying Person") in writing, and the
Indemnifying Person, upon request of the Indemnified Person, shall retain
counsel satisfactory to the Indemnified Person to represent the Indemnified
Person and any others the Indemnifying Person may designate in such proceeding
and shall pay the fees and expenses of such counsel related to such proceeding.
In any such proceeding, any Indemnified Person shall have the right to retain
its own counsel, but the fees and expenses of such counsel shall be at the
expense of such Indemnified Person unless (i) the Indemnifying Person and the
Indemnified Person shall have mutually agreed to the contrary, (ii) the
Indemnifying Person has failed within a reasonable time to retain counsel
satisfactory to the Indemnified Person or (iii) the named parties in any such
proceeding (including any impleaded parties) include both the Indemnifying
Person and the Indemnified Person and representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests
between them. It is understood that the Indemnifying Person shall not, in
connection with any proceeding or related proceeding in the same jurisdiction,
be liable for the reasonable fees and expenses of more than one separate firm
(in addition to any local counsel) for all Indemnified Persons, and that all
such reasonable fees and expenses shall be reimbursed as they are incurred. Any
such separate firm for the Initial Purchasers and such control persons of
Initial Purchasers shall be designated in writing by J.P. Morgan Securities Inc.
and any such separate firm for the Company, its directors and officers and such
control persons of the Company shall be designated in writing by the Company.
The Indemnifying Person shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the Indemnifying Person agrees to
indemnify any Indemnified Person from and against any loss or liability by
reason of such settlement or judgment. Notwithstanding the foregoing sentence,
if at any time an Indemnified Person shall have requested an Indemnifying Person
to reimburse the Indemnified Person for fees and expenses of counsel as
contemplated by the third sentence of this paragraph, the Indemnifying Person
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
days after receipt by such Indemnifying Person of the aforesaid request and (ii)
such Indemnifying Person shall not have reimbursed the Indemnified Person in
accordance with such request prior to the date of such settlement (or delivered
a notice to such Indemnified Person setting forth its good faith objection to
such request's conformity to the provisions of this Section 7). No Indemnifying
Person shall, without the prior written consent of the Indemnified Person,
effect any settlement of any pending or threatened proceeding in respect of
which any Indemnified Person is or could have been a party and indemnity could
have been sought hereunder by such Indemnified Person, unless such settlement
includes an unconditional written release, in form and substance reasonably
satisfactory to the Indemnified Person, of such Indemnified Person from all
liability on claims that are the subject matter of such proceeding.
<PAGE>
 
                                      -18-

     If the indemnification provided for in the first and second paragraphs of
this Section 7 is for any reason unavailable to, or insufficient to hold
harmless, an Indemnified Person in respect of any losses, claims, damages or
liabilities referred to therein, then each Indemnifying Person under such
paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall
contribute to the amount paid or payable by such Indemnified Person as a result
of such losses, claims, damages or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the Initial Purchasers on the other hand from the offering of the
Securities or (ii) if the allocation provided by clause (i) above 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 on the one hand and the Initial Purchasers on the other in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Initial Purchasers on the other shall be deemed to be in the same
respective proportions as the net proceeds from the offering (before deducting
expenses) received by the Company and the total discounts and the commissions
actually received by the Initial Purchasers, in each case as set forth in the
table on the cover of the Offering Memorandum, bear to the aggregate offering
price of the Securities. The relative fault of the Company on the one hand and
the Initial Purchasers on the other 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 or by the Initial Purchasers and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

     The Company and the Initial Purchasers agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata
allocation (even if the Initial Purchasers were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses incurred by such Indemnified Person in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7, in no event shall an Initial
Purchaser be required to contribute any amount in excess of the amount by which
the total price at which the Securities purchased by it were offered exceeds the
amount of any damages that such Initial Purchaser has otherwise been required to
pay or has paid by reason of such untrue or alleged untrue statement or omission
or alleged omission.  No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not 
<PAGE>
 
                                      -19-

guilty of such fraudulent misrepresentation. The Initial Purchasers' obligations
to contribute pursuant to this Section 7 are several in proportion to the

     (A)  In addition to offers pursuant to clause (B)(1) of paragraph 2(ii) of
the Agreement, the Initial Purchasers intend to offer and sell the Securities in
accordance with Regulation S under the Securities Act.  Accordingly, each
Initial Purchaser agrees that neither it, its affiliates nor any persons acting
on its or their behalf has engaged or will engage in any directed selling
efforts with respect to the Securities and it and they have complied and will
comply with the offering restrictions requirement of Regulation S.  Each Initial
Purchaser agrees that, at or prior to confirmation of sale of Securities (other
than a sale pursuant to and in accordance with paragraph 2(ii) of the Agreement
to purchasers described in clause (B)(1) thereof), it will have sent to each
distributor, dealer or person receiving a selling concession, fee or other
remuneration that purchases Securities from it during the restricted period a
confirmation or notice to substantially the following effect:

          "The Securities covered hereby have not been registered under the U.S.
     Securities Act of 1933 (the "Act") and may not be offered and sold within
     the United States or to, or for the account or benefit of, U.S. persons (i)
     as part of their distribution at any time or (ii) otherwise until 40 days
     after the later of the commencement of the offering and the closing date,
     except in either case in accordance with Regulation S (or Rule 144A if
     available) under the Act.  Terms used above have the meaning given to them
     by Regulation S."

Terms used in this paragraph have the meanings given to them by Regulation S.

     Each of the Initial Purchasers further agrees that it has not entered and
will not enter into any contractual arrangement with respect to the distribution
or delivery of the Securities in accordance with this paragraph (A), except with
its affiliates or with the prior written consent of the Company.

     (B)  Each of the Initial Purchasers severally represents and agrees that
(i) it has not offered or sold and prior to the date six months after the date
of issue of the Securities will not offer or sell any Securities to persons in
the United Kingdom except to persons whose ordinary activities involve them in
acquiring, holding, managing or disposing of investments (as principal or agent)
for the purposes of their business or otherwise in circumstances which have not
resulted and will not result in an offer to the public in the United Kingdom
within the meaning of the Public Offers of Securities Regulations 1995, (ii) it
has complied, and will comply with all applicable provisions of the Financial
Services Act 1986 and any regulation promulgated thereto of Great Britain with
respect to anything done by it in relation to the Securities in, from or
otherwise involving the United Kingdom, and (iii) it has only issued or passed
on and will only issue or pass on in the United Kingdom any

document received by it in connection with the issue of the Securities to a
person who is of a kind described in Article 11(3) of the Financial Services
Act 1986 (Investment Advertisements) (Exemptions) Order 1996 or is a person to
whom such document may otherwise lawfully be issued or passed on.

     (C)  Each of the Initial Purchasers agrees that it will not offer, sell or
deliver any of the Securities in any jurisdiction outside the United States
except under circumstances that will result in compliance with the applicable
laws thereof, and that it will take at its own expense whatever action is
required to permit its purchase and resale of the Securities in such
jurisdictions.  Each of the Initial Purchasers understands that no action has
been taken to permit a public offering in any jurisdiction outside the United
States where action would be required for such purposes.  Each of the Initial
Purchasers agrees not to cause any advertisement (other than an announcement of
the consummation of the offer and sale of the Securities) of the Securities to
be published in any newspaper or periodical or posted in any public place and
not to issue any circular relating to the Securities (other than the Offering
Memorandum).

2.   Exchange Offer
     --------------

          (a) The Company agrees to file with the SEC as soon as practicable
     after the Closing Date, but in no event later than the Filing Date, an
     offer to exchange (the "Exchange Offer") any and all of the Registrable
     Securities for a like aggregate principal amount of debt securities of the
     Company which are identical in all material respects to the Notes (the
     "Exchange Securities") (and which are entitled to the benefits of a trust
     indenture which is identical in all material respects to the Indenture
     (other than such changes as are necessary to comply with any requirements
     of the SEC to effect or maintain the qualification of such trust indenture
     under the TIA) and which has been qualified under the TIA), except that the
     Exchange Securities shall have been registered pursuant to an effective
     Registration Statement under the Securities Act and shall contain no
     restrictive legend thereon.  The Company agrees to use its reasonable best
     efforts to keep the Exchange Offer open for at least 20 
<PAGE>
 
                                      -5-

     business days (or longer if required by applicable law) after the date
     notice of the Exchange Offer is mailed to Holders and to consummate the
     Exchange Offer on or prior to the Effectiveness Date. The Exchange Offer
     will be registered under the Securities Act on the appropriate form (the
     "Exchange Registration Statement") and will comply with all applicable
     tender offer rules and regulations under the Exchange Act. If after such
     Exchange Registration Statement is initially declared effective by the SEC,
     the Exchange Offer or the issuance of the Exchange Securities thereunder is
     interfered with by any stop order, injunction or other order or requirement
     of the SEC or any other governmental agency or court such Exchange
     Registration Statement shall be deemed not to have become effective for
     purposes of this Agreement. Each Holder who participates in the Exchange
     Offer will be deemed to represent that any Exchange Securities received by
     it will be acquired in the ordinary course of its business, that at the
     time of the consummation of the Exchange Offer such Holder will have no
     arrangement with any person to participate in the distribution of the
     Exchange Securities in violation of the provisions of the Securities Act,
     and that such Holder is not an affiliate of the Company within the meaning
     of the Securities Act. Upon consummation of the Exchange Offer in
     accordance with this Section 2, the provisions of this Agreement shall
     continue to apply, mutatis mutandis, solely with respect to Registrable
                        ------- --------
     Securities that are Private Exchange Securities and Exchange Securities
     held by Participating Broker-Dealers, and the Company shall have no further
     obligation to register Registrable Securities (other than Private Exchange
     Securities and other than Exchange Securities as to which clause (c)(1)(i)
     hereof applies) pursuant to Section 3 of this Agreement. No securities
     other than the Exchange Securities (and the Company's 8% Senior
     Subordinated Notes due 2008) shall be included in the Exchange Registration
     Statement.

          (b) The Company shall include within the Prospectus contained in the
     Exchange Registration Statement one or more section(s) reasonably
     acceptable to the Initial Purchasers, which shall contain a summary
     statement of the positions taken or policies made by the Staff of the SEC
     with respect to the potential "underwriter" status of any broker-dealer
     that is the beneficial owner (as defined in Rule 13d-3 under the Exchange
     Act) of Exchange Securities received by such broker-dealer in the Exchange
     Offer (a "Participating Broker-Dealer"), whether such positions or policies
     have been publicly disseminated by the Staff of the SEC or such positions
     or policies, in the reasonable judgment of the Initial Purchasers,
     represent the prevailing views of the Staff of the SEC.  Such section(s)
     shall also allow the use of the prospectus by all persons subject to the
     prospectus delivery requirements of the Securities Act, including all
     Participating Broker-Dealers, and include a statement describing the means
     by which Participating Broker-Dealers may resell the Exchange Securities.
<PAGE>
 
                                      -6-

          The Company shall use its reasonable best efforts to keep the Exchange
     Registration Statement effective and to amend and supplement the Prospectus
     contained therein in order to permit such Prospectus to be lawfully
     delivered by all persons subject to the prospectus delivery requirements of
     the Securities Act for such period of time as such persons must comply with
     such requirements in order to resell the Exchange Securities, provided that
                                                                   --------     
     such period shall not exceed 180 days (or such longer period if extended
     pursuant to the last paragraph of Section 5) (the "Applicable Period").
     Notwithstanding the foregoing, the Company shall have no obligation to keep
     the Exchange Registration Statement effective or to amend and supplement
     the Prospectus contained therein in the event that the Company has not
     received written notice within 30 days following the completion of the
     Exchange Offer that a participating Broker-Dealer received Exchange
     Securities in the Exchange Offer.

          If, prior to consummation of the Exchange Offer, an Initial Purchaser
     holds any Notes acquired by it and having the status of an unsold allotment
     in the initial distribution, the Company upon the request of such Initial
     Purchaser shall, simultaneously with the delivery of the Exchange
     Securities in the Exchange Offer, issue and deliver to each such Initial
     Purchaser, in exchange (the "Private Exchange") for the Notes held by such
     Initial Purchaser, a like principal amount of debt securities of the
     Company that are identical in all material respects to the Exchange
     Securities (the "Private Exchange Securities") (and which are issued
     pursuant to the same indenture as the Exchange Securities) except for the
     placement of a restrictive legend on such Private Exchange Securities.
     The Private Exchange Securities shall bear the same CUSIP number as the
     Exchange Securities.  Interest on the Exchange Securities and Private
     Exchange Securities will accrue from the last interest payment date on
     which interest was paid on the Notes surrendered in exchange therefor or,
     if no interest has been paid on the Notes, from the Issue Date.

          Any indenture under which the Exchange Securities or  the Private
     Exchange Securities will be issued shall provide that the holders of any of
     the Exchange Securities and the Private Exchange Securities will vote and
     consent together on all matters (to which such holders are entitled to vote
     or consent) as one class and that none of the holders of the Exchange
     Securities and the Private Exchange Securities will have the right to vote
     or consent as a separate class on any matter (to which such holders are
     entitled to vote or consent).

          (c) If (1) prior to the consummation of the Exchange Offer, the
     Company reasonably determines in good faith or Holders of at least a
     majority in aggregate principal amount of the Registrable Securities notify
     the Company that they have reasonably determined in good faith that (i) in
     the opinion of counsel, the Exchange 
<PAGE>
 
                                      -7-

     Securities would not, upon receipt, be tradeable by such Holders who are
     not affiliates of the Company without restriction under the Securities Act
     and without restrictions under applicable blue sky or state securities laws
     or (ii) in the opinion of counsel, the SEC is unlikely to permit the
     consummation of the Exchange Offer and/or (2) subsequent to the
     consummation of the Private Exchange, holders of at least a majority in
     aggregate principal amount of the Private Exchange Securities so request
     with respect to the Private Exchange Securities and/or (3) the Exchange
     Offer is commenced and not consummated prior to the 45th day following the
     Consummation Date for any reason, then the Company shall promptly deliver
     to the Holders and the Trustee notice thereof (the "Shelf Notice") and
     shall thereafter file an Initial Shelf Registration as set forth in Section
     3 (which only in the circumstances contemplated by clause (2) of this
     sentence will relate solely to the Private Exchange Securities) pursuant to
     Section 3. The parties hereto agree that, following the delivery of a Shelf
     Notice to the Holders of Registrable Securities (only in the circumstances
     contemplated by clauses (1) and/or (3) of the preceding sentence), the
     Company shall not have any further obligation to conduct the Exchange Offer
     or the Private Exchange under this Section 2.

3.   Shelf Registration
     ------------------

          If a Shelf Notice is delivered as contemplated by Section 2(c), then:

          (a) Initial Shelf Registration.  The Company shall as promptly as
              --------------------------                                   
     reasonably practicable prepare and file with the SEC a Registration
     Statement for an offering to be made on a continuous basis pursuant to Rule
     415 covering all of the Registrable Securities (the "Initial Shelf
     Registration").  If the Company shall have not yet filed an Exchange
     Registration Statement, the Company shall use its reasonable best efforts
     to file with the SEC the Initial Shelf Registration on or prior to the
     Filing Date.  Otherwise, the Company shall use its reasonable best efforts
     to file with the SEC the Initial Shelf Registration within 60 days of the
     delivery of the Shelf Notice.  The Initial Shelf Registration shall be on
     Form S-2 or S-3 or another appropriate form permitting registration of such
     Registrable Securities for resale by such holders in the manner or manners
     designated by them (including, without limitation, one or more underwritten
     offerings).  The Company shall not permit any securities other than the
     Registrable Securities to be included in the Initial Shelf Registration or
     any Subsequent Shelf Registration.  The Company shall use its reasonable
     best efforts to cause the Initial Shelf Registration to be declared
     effective under the Securities Act on or prior to the 120th day after the
     filing thereof with the SEC and to keep the Initial Shelf Registration
     continuously effective under the Securities Act until the date which is 24
     months from the Issue Date (subject to extension pursuant to the last
     paragraph of Section 5 hereof) (the "Effectiveness Period"), or such
<PAGE>
 
                                      -8-

     shorter period ending when (i) all Registrable Securities covered by the
     Initial Shelf Registration have been sold in the manner set forth and as
     contemplated in the Initial Shelf Registration or (ii) a Subsequent Shelf
     Registration covering all of the Registrable Securities has been declared
     effective under the Securities Act.

          (b) Subsequent Shelf Registrations.  If the Initial Shelf Registration
              ------------------------------                                    
     or any Subsequent Shelf Registration ceases to be effective for any reason
     at any time during the Effectiveness Period (other than because of the sale
     of all of the securities registered thereunder), the Company shall use its
     reasonable best efforts to obtain the prompt withdrawal of any order
     suspending the effectiveness thereof, and in any event shall within 45 days
     of such cessation of effectiveness amend the Shelf Registration in a manner
     reasonably expected to obtain the withdrawal of the order suspending the
     effectiveness thereof, or file an additional "shelf" Registration Statement
     pursuant to Rule 415 covering all of the Registrable Securities (a
     "Subsequent Shelf Registration").  If a Subsequent Shelf Registration is
     filed, the Company shall use its reasonable best efforts to cause the
     Subsequent Shelf Registration to be declared effective as soon as
     practicable after such filing and to keep such Registration Statement
     continuously effective for a period equal to the number of days in the
     Effectiveness Period less the aggregate number of days during which the
     Initial Shelf Registration or any Subsequent Shelf Registration was
     previously continuously effective.  As used herein the term "Shelf
     Registration" means the Initial Shelf Registration and any Subsequent Shelf
     Registration.

          (c) Supplements and Amendments.  The Company shall promptly supplement
              --------------------------                                        
     and amend the Shelf Registration if required by the rules, regulations or
     instructions applicable to the registration form used for such Shelf
     Registration, if required by the Securities Act, or if reasonably requested
     by the Holders of a majority in aggregate principal amount of the
     Registrable Securities covered by such Registration Statement or by any
     underwriter of such Registrable Securities.

4.   Additional Interest
     -------------------

          (a) The Company and the Initial Purchasers agree that the Holders of
     Registrable Securities will suffer damages if the Company fails to fulfill
     its obligations under Section 2 or Section 3 hereof and that it would not
     be feasible to ascertain the extent of such damages with precision.
     Accordingly, the Company agrees to pay, as liquidated damages, additional
     interest on the Registrable Securities ("Additional Interest") under the
     circumstances and to the extent set forth below (each of which shall be
     given independent effect and shall not be duplicative):
<PAGE>
 
                                      -9-

          (i)    if neither the Exchange Registration Statement nor the Initial
     Shelf Registration has been filed on or prior to the Filing Date,
     Additional Interest shall accrue on the Registrable Securities over and
     above the stated interest at a rate of .25% per annum for the first 90 days
     immediately following the Filing Date, such Additional Interest rate
     increasing by an additional .25% per annum at the beginning of each
     subsequent 90-day period;

          (ii)   if neither the Exchange Registration Statement nor the Initial
     Shelf Registration is declared effective by the SEC on or prior to the
     Effectiveness Date, Additional Interest shall accrue on the Registrable
     Securities included or which should have been included in such Registration
     Statement over and above the stated interest at a rate of .25% per annum
     for the first 90 days immediately following the day after the Effectiveness
     Date, such Additional Interest rate increasing by an additional .25% per
     annum at the beginning of each subsequent 90-day period; and

          (iii)  if (A) the Company has not exchanged Exchange Securities for
     all Notes validly tendered in accordance with the terms of the Exchange
     Offer on or prior to the Consummation Date or (B) the Exchange Registration
     Statement ceases to be effective at any time prior to the time that the
     Exchange Offer is consummated or (C) if applicable, the Shelf Registration
     has been declared effective and such Shelf Registration ceases to be
     effective at any time during the Effectiveness Period, then Additional
     Interest shall accrue on the Registrable Securities (over and above any
     interest otherwise payable on the Registrable Securities) at a rate of .25%
     per annum for the first 90 days commencing on the (x) 181st day after the
     Issue Date, in the case of (A) above, or (y) the day the Exchange
     Registration Statement ceases to be effective in the case of (B) above, or
     (z) the day such Shelf Registration ceases to be effective in the case of
     (C) above, such Additional Interest rate increasing by an additional .25%
     per annum at the beginning of each such subsequent 90-day period;

provided, however, that the Additional Interest rate on the Registrable
- --------  -------                                                      
Securities may not exceed at any one time in the aggregate 1.0% per annum; and
provided, further, that (1) upon the filing of the Exchange Registration
- --------  -------                                                       
Statement or a Shelf Registration as required hereunder (in the case of clause
(i) of this Section 4), (2) upon the effectiveness of the Exchange Registration
Statement or the Shelf Registration as required hereunder (in the case of clause
(ii) of this Section 4), or (3) upon the exchange of Exchange Securities for all
Notes tendered (in the case of clause (iii)(A) of this Section 4), or upon the
effectiveness of the Exchange Registration Statement which had ceased to remain
effective (in the case of (iii)(B) of this Section 4), or upon the effectiveness
of the Shelf Registration which had ceased to remain effective (in the case of
(iii)(C) of this Section 4), Additional Interest on the Registrable Securities
as a result of such clause (or the relevant subclause thereof), as the case may
be, shall cease to accrue.  It being understood and agreed that, 
<PAGE>
 
                                      -10-

notwithstanding any provision to the contrary, so long as any Registrable
Security is then covered by an effective Shelf Registration Statement, no
Additional Interest shall accrue on such Registrable Security.

          (b) The Company shall notify the Trustee within one business day after
     each and every date on which an event occurs in respect of which Additional
     Interest is required to be paid (an "Event Date").  The Company shall pay
     the Additional Interest due on the Registrable Securities by depositing
     with the Trustee, in trust, for the benefit of the Holders thereof, on or
     before the applicable semi-annual interest payment date, immediately
     available funds in sums sufficient to pay the Additional Interest then due
     to Holders of Registrable Securities.  The Additional Interest due shall be
     payable on each interest payment date to the record Holder of Registrable
     Securities entitled to receive the interest payment to be made on such date
     as set forth in the Indenture.  The amount of Additional Interest will be
     determined by multiplying the applicable Additional Interest rate by the
     principal amount of the affected Registrable Securities of such Holders,
     multiplied by a fraction, the numerator of which is the number of days such
     Additional Interest rate was applicable during such period (determined on
     the basis of a 360-day year comprised of twelve 30-day months and, in the
     case of a partial month, the actual number of days elapsed), and the
     denominator of which is 360.  Each obligation to pay Additional Interest
     shall be deemed to accrue immediately following the occurrence of the
     applicable Event Date.  The parties hereto agree that the Additional
     Interest provided for in this Section 4 constitutes a reasonable estimate
     of the damages that may be incurred by Holders of Registrable Securities by
     reason of the failure of a Shelf Registration or Exchange Offer to be filed
     or declared effective, or a Shelf Registration to remain effective, as the
     case may be, in accordance with this Section 4.

5.   Registration Procedures
     -----------------------

          In connection with the registration of any Registrable Securities
pursuant to Sections 2 or 3 hereof, the Company shall effect such registrations
to permit the sale of such Registrable Securities in accordance with the
intended method or methods of disposition thereof, and pursuant thereto the
Company shall:

          (a) Use its reasonable best efforts to prepare and file with the SEC,
     as soon as practicable after the date hereof but in any event prior to the
     Filing Date in the case of the Exchange Registration Statement and the 45th
     day following the Consummation Date in the case of the Shelf Registration
     Statement, a Registration Statement or Registration Statements as
     prescribed by Section 2 or 3, and to use its reasonable best efforts to
     cause each such Registration Statement to become effective and remain
     effective as provided herein, provided that, if (1) such filing is pursuant
                                   --------                                     
<PAGE>
 
                                      -11-

     to Section 3, or (2) a Prospectus contained in an Exchange Registration
     Statement filed pursuant to Section 2 is required to be delivered under the
     Securities Act by any Participating Broker-Dealer who seeks to sell
     Exchange Securities during the Applicable Period, before filing any
     Registration Statement or Prospectus or any amendments or supplements
     thereto, the Company shall upon written request furnish to and afford the
     Holders of the Registrable Securities and each such Participating Broker-
     Dealer, as the case may be, covered by such Registration Statement, their
     counsel and the managing underwriters, if any, a reasonable opportunity to
     review copies of all such documents (including copies of any documents to
     be incorporated by reference therein and all exhibits thereto) proposed to
     be filed.

          (b) Prepare and file with the SEC such amendments and post-effective
     amendments to each Shelf Registration or Exchange Registration Statement,
     as the case may be, as may be necessary to keep such Registration Statement
     continuously effective for the Effectiveness Period or the Applicable
     Period, as the case may be; cause the related Prospectus to be supplemented
     by any required Prospectus supplement, and as so supplemented to be filed
     pursuant to Rule 424 (or any similar provisions then in force) under the
     Securities Act; and comply with the provisions of the Securities Act, the
     Exchange Act and the rules and regulations of the SEC promulgated
     thereunder applicable to it with respect to the disposition of all
     securities covered by such Registration Statement as so amended or in such
     Prospectus as so supplemented and with respect to the subsequent resale of
     any securities being sold by a Participating Broker-Dealer covered by any
     such Prospectus; the Company shall not be deemed to have used its
     reasonable best efforts to keep a Registration Statement effective  during
     the Applicable Period if the Company voluntarily takes any action that
     would result in selling Holders of the Registrable Securities covered
     thereby or Participating Broker-Dealers seeking to sell Exchange Securities
     not being able to sell such Registrable Securities or such Exchange
     Securities during that period unless such action is in the best interest of
     the Company (as determined by its board of directors), required by
     applicable law or unless the Company complies with this Agreement,
     including without limitation, the provisions of paragraph 5(k) hereof and
     the last paragraph of this Section 5.

          (c) If (1) a Shelf Registration is filed pursuant to Section 3, or (2)
     a Prospectus contained in an Exchange Registration Statement filed pursuant
     to Section 2 is required to be delivered under the Securities Act by any
     Participating Broker-Dealer who seeks to sell Exchange Securities during
     the Applicable Period, notify the selling Holders of Registrable
     Securities, or each such Participating Broker-Dealer, as the case may be,
     their counsel and the managing underwriters, if any, who have provided the
     Company with their names and addresses promptly (but in any event within
     two business days), and confirm such notice in writing, (i) when a
<PAGE>
 
                                      -12-

     Prospectus or any Prospectus supplement or post-effective amendment has
     been filed, and, with respect to a Registration Statement or any post-
     effective amendment, when the same has become effective under the
     Securities Act (including in such notice a written statement that any
     Holder may, upon request, obtain, without charge, one conformed copy of
     such Registration Statement or post-effective amendment including financial
     statements and schedules, documents incorporated or deemed to be
     incorporated by reference and exhibits), (ii) of the issuance by the SEC of
     any stop order suspending the effectiveness of a Registration Statement or
     of any order preventing or suspending the use of any preliminary prospectus
     or the initiation of any proceedings for that purpose, (iii) of the receipt
     by the Company of any notification with respect to the suspension of the
     qualification or exemption from qualification of a Registration Statement
     or any of the Registrable Securities or the Exchange Securities to be sold
     by any Participating Broker-Dealer for offer or sale in any jurisdiction,
     or the initiation or threatening of any proceeding for such purpose, (iv)
     of the happening of any event or any information becoming known that makes
     any statement made in such Registration Statement or related Prospectus or
     any document incorporated or deemed to be incorporated therein by reference
     untrue in any material respect or that requires the making of any changes
     in such Registration Statement, Prospectus or documents so that, in the
     case of the Registration Statement, 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 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, and (v) of the Company's reasonable determination that a post-
     effective amendment to a Registration Statement would be appropriate.

          (d) If (1) a Shelf Registration is filed pursuant to Section 3, or (2)
     a Prospectus contained in an Exchange Registration Statement filed pursuant
     to Section 2 is required to be delivered under the Securities Act by any
     Participating Broker-Dealer who seeks to sell Exchange Securities during
     the Applicable Period, use its reasonable best efforts to prevent the
     issuance of any order suspending the effectiveness of a Registration
     Statement or of any order preventing or suspending the use of a Prospectus
     or suspending the qualification (or exemption from qualification) of any of
     the Registrable Securities or the Exchange Securities to be sold by any
     Participating Broker-Dealer, for sale in any jurisdiction, and, if any such
     order is issued, to use its reasonable best efforts to obtain the
     withdrawal of any such order at the earliest possible moment.
<PAGE>

     Securities covered by the applicable Registration Statement, provided that
                                                                  --------

     Company, a supplement or post-effective amendment to the Registration
     Statement or a supplement to the related Prospectus or any document
     incorporated or deemed to be incorporated therein by reference, or file any
     other required document so that, as thereafter delivered to the purchasers
     of the Registrable Securities being sold thereunder or to the purchasers of
     the Exchange Securities to whom such Prospectus will be delivered by a
     Participating Broker-Dealer, any such Prospectus will not contain an untrue
     statement of a material fact or omit to state 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.

          (l) Use its reasonable best efforts to cause the Registrable
     Securities covered by a Registration Statement or the Exchange Securities,
     as the case may be, to be rated with the appropriate rating agencies, if so
     requested by the Holders of a majority in aggregate principal amount of
     Registrable Securities covered by such Registration Statement or the
     Exchange Securities, as the case may be, or the managing underwriters, if
     any.

          (o) In connection with an underwritten offering of Registrable
     Securities pursuant to a Shelf Registration, enter into an underwriting
     agreement as is customary in underwritten offerings and take all such other
     actions as are reasonably requested by the managing underwriters in order
     to expedite or facilitate the registration or the disposition of such
     Registrable Securities, and in such connection, (i) make such
     representations and warranties to the underwriters, with respect to the
     business of the Company and its subsidiaries, if any, and the Registration

     obtain "cold comfort" letters and updates thereof in form and substance

     or of any business acquired by the Company for which financial statements
     and financial data are, or are required to be, included in the Registration
     Statement), addressed to each of the underwriters, such letters to be in
     customary form and covering matters of the type customarily covered in
     "cold comfort" letters in connection with underwritten offerings and such
     other matters as may be reasonably requested by underwriters; and (iv) if
     an underwriting agreement is entered into, the same shall contain
     indemnification provisions and procedures no less favorable than those set
     forth in Section 7 hereof (or such other provisions and procedures
     acceptable to Holders of a majority in aggregate principal amount of
     Registrable Securities covered by such Registration Statement and the
     managing underwriters or agents) with respect to all parties to be
     indemnified pursuant to said Section. The above shall be done at each
     closing under such underwriting agreement, or as and to the extent required
     thereunder.

          (p) If (1) a Shelf Registration is filed pursuant to Section 3, or (2)
     a Prospectus contained in an Exchange Registration Statement filed pursuant
     to Section 2 is required to be delivered under the Securities Act by any
     Participating Broker-Dealer who seeks to sell Exchange Securities during
     the Applicable Period, make available for inspection by any selling Holder
     of such Registrable Securities being sold, or each such Participating
     Broker-Dealer, as the case may be, any underwriter participating in any
     such disposition of Registrable Securities, if any, and any attorney,
     accountant or other agent retained by any such selling holder or each such
     Participating Broker-Dealer, as the case may be, or underwriter
     (collectively, the "Inspectors"), at the offices where normally kept,
     during reasonable business hours, all financial and other records,
     pertinent corporate documents and properties of the Company and its
     subsidiaries (collectively, the "Records"), as shall be reasonably
     necessary to enable them to exercise any applicable due diligence
     responsibilities, and cause the officers, directors and employees of the
     Company to supply all information in each case reasonably requested by any
     such Inspector in connection with such Registration Statement. Records
     determined in good faith by the 
<PAGE>
 
                                      -17-

     Company to be confidential shall not be disclosed by any Inspector notified
     of such determination unless (i) the disclosure of such Records is
     necessary to avoid or correct a misstatement or omission in such
     Registration Statement, (ii) the release of such Records is ordered
     pursuant to a subpoena or other order from a court of competent
     jurisdiction or (iii) the information in such Records has been made
     generally available to the public. Each selling Holder of such Registrable
     Securities and each such Participating Broker-Dealer will be required to
     agree that information obtained by it as a result of such inspections shall
     be deemed confidential and shall not be used by it as the basis for any
     market transactions in the securities of the Company unless and until such
     is made generally available to the public. Each selling Holder of such
     Registrable Securities and each such Participating Broker-Dealer will be
     required to further agree that it will, upon learning that disclosure of
     such Records is sought in a court of competent jurisdiction, give notice to
     the Company and allow the Company at its expense to undertake appropriate
     action to prevent disclosure of the Records deemed confidential.

          (q) Provide an indenture trustee for the Registrable Securities or the
     Exchange Securities, as the case may be, and cause the Indenture or the
     trust indenture provided for in Section 2(a), as the case may be, to be
     qualified under the TIA not later than the effective date of the Exchange
     Offer or the first Registration Statement relating to the Registrable
     Securities; and in connection therewith, cooperate with the trustee under
     any such indenture and the holders of the Registrable Securities, to effect
     such changes to such indenture as may be required for such indenture to be
     so qualified in accordance with the terms of the TIA; and execute, and use
     its reasonable best efforts to cause such trustee to execute, all documents
     as may be required to effect such changes, and all other forms and
     documents required to be filed with the SEC to enable such indenture to be
     so qualified in a timely manner.

          (r) Comply in all material respects with all applicable rules and
     regulations of the SEC and make generally available to its securityholders
     earning statements satisfying the provisions of Section 11(a) of the
     Securities Act and Rule 158 thereunder (or any similar rule promulgated
     under the Securities Act) no later than 90 days after the end of any 12-
     month period (i) commencing at the end of any fiscal quarter in which
     Registrable Securities are sold to underwriters in a firm commitment or
     best efforts underwritten offering and (ii) if not sold to underwriters in
     such an offering, commencing on the first day of the first fiscal quarter
     of the Company after the effective date of a Shelf Registration Statement,
     which statements shall cover said 12-month periods.

          (s) If an Exchange Offer or a Private Exchange is to be consummated,
     upon delivery of the Registrable Securities by Holders to the Company (or
     to such 
<PAGE>
 
                                      -18-

     other Person as directed by the Company) in exchange for the Exchange
     Securities or the Private Exchange Securities, as the case may be, the
     Company shall mark, or caused to be marked, on such Registrable Securities
     that such Registrable Securities are being cancelled in exchange for the
     Exchange Securities or the Private Exchange Securities, as the case may be;
     in no event shall such Registrable Securities be marked as paid or
     otherwise satisfied.

          (t) Reasonably cooperate with each seller of Registrable Securities
     covered by any Registration Statement and each underwriter, if any,
     participating in the disposition of such Registrable Securities and their
     respective counsel in connection with any filings required to be made with
     the National Association of Securities Dealers, Inc. (the "NASD").

          (u) The Company will use its best efforts to (i) if the Registrable
     Securities have been rated prior to the initial sale of such Registrable
     Securities, confirm such ratings will apply to the Registrable Securities
     covered by a Registration Statement or (ii) if the Registrable Securities
     were not previously rated, cause the Registrable Securities covered by a
     Registration Statement to be rated with the appropriate rating agencies, if
     so requested by Holders of a majority in aggregate principal amount of the
     Registrable Securities covered by such Registration Statement, or by the
     managing underwriters, if any.

          (v) Use its reasonable best efforts to take all other steps necessary
     to effect the registration of the Registrable Securities covered by a
     Registration Statement contemplated hereby.

          The Company may require each seller of Registrable Securities or
Participating Broker-Dealer as to which any registration is being effected to
furnish to the Company such information regarding such seller or Participating
Broker-Dealer and the distribution of such Registrable Securities or Exchange
Securities to be sold by such Participating Broker-Dealer, as the case may be,
as the Company may, from time to time, reasonably request.  The Company may
exclude from such registration the Registrable Securities of any seller or
Participating Broker-Dealer who unreasonably fails to furnish such information
within a reasonable time after receiving such request.  Each seller as to which
any Shelf Registration is being effected is deemed to agree to furnish promptly
to the Company all information required to be disclosed in order to make the
information previously furnished to the Company by such seller not materially
misleading.

          Each Holder of Registrable Securities and each Participating Broker-
Dealer agrees by acquisition of such Registrable Securities or Exchange
Securities to be sold by such Participating Broker-Dealer, as the case may be,
that, upon receipt of any notice from 
<PAGE>
 
                                      -19-

the Company of the happening of any event of the kind described in Section
5(c)(ii), 5(c)(iii), 5(c)(iv), or 5(c)(v), such Holder will forthwith
discontinue disposition of such Registrable Securities covered by such
Registration Statement or Prospectus or Exchange Securities to be sold by such
Participating Broker-Dealer, as the case may be, until such holder's receipt of
the copies of the supplemented or amended Prospectus contemplated by Section
5(k), or until it is advised in writing (the "Advice") by the Company that the
use of the applicable Prospectus may be resumed, and has received copies of any
amendments or supplements thereto. In the event the Company shall give any such
notice, each of the Effectiveness Period and the Applicable Period shall be
extended by the number of days during such periods from and including the date
of the giving of such notice to and including the date when each seller of
Registrable Securities covered by such Registration Statement or Exchange
Securities to be sold by such Participating Broker-Dealer, as the case may be,
shall have received (x) the copies of the supplemented or amended Prospectus
contemplated by Section 5(k) or (y) the Advice.

6.   Registration Expenses
     ---------------------

          (a) All fees and expenses incident to the performance of or compliance
     with this Agreement by the Company shall be borne by the Company whether or
     not the Exchange Offer or a Shelf Registration is filed or becomes
     effective, including, without limitation, (i) all registration and filing

     Exchange Securities, or (y) as provided in Section 5(h), in the case of

     Registrable Securities or Exchange Securities in a form eligible for
     deposit with DTC and of printing prospectuses if the printing of
     prospectuses is requested by the managing underwriters, if any, or, in
     respect of Registrable Securities or Exchange Securities to be sold by any
     Participating Broker-Dealer during the Applicable Period, by the Holders of
     a majority in aggregate principal amount of the Registrable Securities
     included in any Registration Statement or of such Exchange Securities, as
     the case may be), (iii) messenger, telephone and delivery expenses, (iv)

     agreements, indentures and any other documents necessary in order to comply
     with this Agreement. In the event of an underwritten offering of
     Registrable Securities the Company shall not be responsible for any
     "roadshow expenses" in connection therewith except for those of its
     officers and directors in attending roadshow presentations..

          (b) In connection with any Shelf Registration hereunder, the Company
     shall reimburse the Holders of the Registrable Securities being registered
     in such registration for the reasonable fees and disbursements of not more
     than one counsel (in addition to appropriate local counsel) chosen by the
     Holders of a majority in aggregate principal amount of the Registrable
     Securities to be included in such Registration Statement.  Such Holders
     shall be responsible for any and all other out-of-pocket expenses of the
     Holders of Registrable Securities incurred in connection with the
     registration of the Registrable Securities.

7.   Indemnification
     ---------------

          The Company agrees to indemnify and hold harmless each Holder of
Registrable Securities if a Shelf Registration is filed pursuant to Section 3
and each Participating Broker-Dealer selling Exchange Securities during the
Applicable Period, the officers and directors of each such person, and each
person, if any, who controls any such person within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act (each, a
"Participant"), from and against any and all losses, claims, damages and
liabilities (including, without limitation, the legal fees and other expenses
incurred in connection with any suit, action or proceeding or any claim
asserted) caused by any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement (or any amendment thereto)
or Prospectus (as amended or supplemented if the Company shall have furnished
any amendments or supplements thereto) or any preliminary prospectus, or caused
by any 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 
<PAGE>
 
                                      -21-

under which they were made, not misleading, except insofar as such losses,
claims, damages or liabilities are caused by any untrue statement or omission or
alleged untrue statement or omission made in reliance upon and in conformity
with information relating to any Participant furnished to the Company in writing
by such Participant expressly for use therein; provided that the foregoing
                                               --------
indemnity with respect to any preliminary prospectus shall not inure to the
benefit of any Participant (or to the benefit of any person controlling such
Participant) from whom the person asserting any such losses, claims, damages or
liabilities purchased Registrable Securities or Exchange Securities if such
untrue statement or omission or alleged untrue statement or omission made in
such preliminary prospectus is completely remedied in the related Prospectus (as
amended or supplemented if the Company shall have furnished any amendments or
supplements thereto) and a copy of the related Prospectus (as so amended or
supplemented) shall not have been furnished to such person at or prior to the
sale of such Registrable Securities or Exchange Securities, as the case may be,
to such person, if required by law.

          Each Participant will be required to agree, severally and not jointly,
to indemnify and hold harmless the Company, its directors, its officers and each
person who controls the Company within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to each Participant, but only with
reference to information relating to such Participant furnished to the Company
in writing by such Participant expressly for use in any Registration Statement
or Prospectus, any amendment or supplement thereto, or any preliminary
prospectus.  The liability of any Participant under this paragraph shall in no
event exceed the proceeds received by such Participant from sales of Registrable
Securities giving rise to such obligations.

          If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, such person (the "Indemnified Person") shall promptly
notify the person against whom such indemnity may be sought (the "Indemnifying
Person") in writing, and the Indemnifying Person, upon request of the
Indemnified Person, shall retain counsel satisfactory to the Indemnified Person
to represent the Indemnified Person and any others the Indemnifying Person may
designate in such proceeding and shall pay the fees and expenses of such counsel
related to such proceeding.  In any such proceeding, any Indemnified Person
shall have the right to retain its own counsel, but the fees and expenses of
such counsel shall be at the expense of such Indemnified Person unless (i) the
Indemnifying Person and the Indemnified Person shall have mutually agreed to the
contrary, (ii) the Indemnifying Person has failed within a reasonable time to
retain counsel satisfactory to the Indemnified Person or (iii) the named parties
in any such proceeding (including any impleaded parties) include both the
Indemnifying Person and the Indemnified Person and representation of both
parties by the 
<PAGE>
 
                                      -22-

same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood that the Indemnifying Person shall not,
in connection with any proceeding or related proceeding in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all Indemnified Persons, and that all
such fees and expenses shall be reimbursed as they are incurred. Any such
separate firm for the Participants and such control persons of Participants
shall be designated in writing by Participants who sold a majority in interest
of Registrable Securities sold by all such Participants and any such separate
firm for the Company, its directors, officers and such control persons of the
Company shall be designated in writing by the Company. The Indemnifying Person
shall not be liable for any settlement of any proceeding effected without its
written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, the Indemnifying Person agrees to indemnify any
Indemnified Person from and against any loss or liability by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an Indemnified Person shall have requested an Indemnifying Person to reimburse
the Indemnified Person for fees and expenses actually incurred by counsel as
contemplated by the third sentence of this paragraph, the Indemnifying Person
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
days after receipt by such Indemnifying Person of the aforesaid request and (ii)
such Indemnifying Person shall not have reimbursed the Indemnified Person in
accordance with such request prior to the date of such settlement (or delivered
a notice to such Indemnified Person setting forth its good faith objection to
such request's conformity to the provisions of this Section 7). No Indemnifying
Person shall, without the prior written consent of the Indemnified Person,
effect any settlement of any pending or threatened proceeding in respect of
which any Indemnified Person is or could have been a party and indemnity could
have been sought hereunder by such Indemnified Person, unless such settlement
includes an unconditional written release in form and substance satisfactory to
the Indemnified Person, of such Indemnified Person from all liability on claims
that are the subject matter of such proceeding.

          If the Indemnification provided for in the first and second paragraphs
of this Section 7 is unavailable to, or insufficient to hold harmless, an
Indemnified Person in respect of any losses, claims, damages or liabilities
referred to therein, then each Indemnifying Person under such paragraph, in lieu
of indemnifying such Indemnified Person thereunder, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect
the relative fault of the Company on the one hand and the Participants on the
other in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations.  The relative fault of the Company on the one hand and the
Participants on the other shall be determined by refer-
<PAGE>
 
                                      -23-

ence 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 or by the Participants and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

          The parties shall agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
                                                           --- ----           
(even if the Participants were treated as one entity for such purpose) or by any
other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph.  The amount
paid or payable by an Indemnified Person as a result of the losses, claims,
damages and liabilities referred to in the immediately preceding paragraph shall
be deemed to include, subject to the limitations set forth above, any legal or
other expenses incurred by such Indemnified Person in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section 7, in no event shall a Participant be required to
contribute any amount in excess of the amount by which proceeds received by such
Participant from sales of Registrable Securities exceeds the amount of any
damages that such Participant has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission.  No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          The indemnity and contribution agreements contained in this Section 7
will be in addition to any liability which the Indemnifying Persons may
otherwise have to the Indemnified Persons referred to above.

8.   Rule 144 and Rule 144A
     ----------------------

          The Company covenants that it will file the reports required to be
filed by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the SEC thereunder in a timely manner and, if at any time
the Company is not required to file such reports, it will, upon the request of
any Holder of Registrable Securities, within a reasonable time period make
publicly available other information so long as necessary to permit sales
pursuant to Rule 144 and Rule 144A under the Securities Act.  The Company
further covenants that it will take such further action as any Holder of
Registrable Securities may reasonably request, all to the extent required from
time to time to enable such holder to sell Registrable Securities without
registration under the Securities Act within the limitation of the exemptions
provided by (a) Rule 144 and Rule 144A under the Securities Act, as such Rules
may be amended from time to time, or (b) any similar rule or regulation
hereafter adopted by the SEC.

9.   Underwritten Registrations
     --------------------------

          Nothing in this Agreement shall be interpreted so as to obligate the
Company to participate in an underwritten offering of Registrable Securities
covered by any Shelf Registration.  The Company's decision as to whether to
cooperate with a proposed underwritten offering shall be at its sole discretion.

          If any of the Registrable Securities covered by any Shelf Registration
are to be sold in an underwritten offering, the investment banker or investment
bankers and manager or managers that will manage the offering will be selected
by the Holders of a majority in aggregate principal amount of such  Registrable
Securities included in such offering and be reasonably acceptable to the
Company.

          No Holder of Registrable Securities may participate in any
underwritten registration hereunder unless such Holder (a) agrees to sell such
Holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements.

10.  Miscellaneous
     -------------

          (a) Remedies.  In the event of a breach by the Company of any of its
              --------                                                        
     obligations under this Agreement, each Holder of Registrable Securities, in
     addition to being entitled to exercise all rights provided herein, in the
     Indenture or, in the case of the Initial Purchasers, in the Purchase
     Agreement or granted by law, including recovery of damages, will be
     entitled to specific performance of its rights under this Agreement.  The
     Company agrees that monetary damages would not be adequate compensation for
     any loss incurred by reason of a breach by it of any of the provisions of
     this Agreement and hereby further agree that, in the event of any action
     for specific performance in respect of such breach, the Company shall waive
     the defense that a remedy at law would be adequate.

          (b) No Inconsistent Agreements.  The Company has not, as of the date
              --------------------------                                      
     hereof, entered and shall not, after the date of this Agreement, enter into
     any agreement with respect to any of its securities that is inconsistent
     with the rights granted to the Holders of Registrable Securities in this
     Agreement or otherwise conflicts with the provisions hereof.  The Company
     has not entered and will not enter into any agreement with respect to any
     of its securities which will grant to any Person piggy-back rights with
     respect to a Registration Statement.

                                      -25-

          (c)    Adjustments Affecting Registrable Securities. The Company shall
                 --------------------------------------------     
     not, directly or indirectly, take any action with respect to the
     Registrable Securities as a class that would adversely affect the ability
     of the Holders of Registrable Securities to include such Registrable
     Securities in a registration undertaken pursuant to this Agreement.

          (d)    Amendments and Waivers. The provisions of this Agreement,
                 ----------------------                                    
     including the provisions of this sentence, may not be amended, modified or
     supplemented, and waivers or consents to departures from the provisions
     hereof may not be given, unless the Company has obtained the written
     consent of Holders of at least a majority of the then outstanding aggregate
     principal amount of Registrable Securities.  Notwithstanding the foregoing,
     a waiver or consent to depart from the provisions hereof with respect to a
     matter that relates exclusively to the rights of Holders of Registrable
     Securities whose securities are being sold pursuant to a Registration
     Statement and that does not directly or indirectly affect, impair, limit or
     compromise the rights of other Holders of Registrable Securities may be
     given by Holders of at least a majority in aggregate principal amount of
     the Registrable Securities being sold by such Holders pursuant to such
     Registration Statement, provided that the provisions of this sentence may
                             --------                                         
     not be amended, modified or supplemented except in accordance with the
     provisions of the immediately preceding sentence.

          (e)    Notices. All notices and other communications (including
                 -------
     without limitation any notices or other communications to the Trustee)
     provided for or permitted hereunder shall be made in writing by hand-
     delivery, registered first-class mail, next-day air courier or telecopier:

            (i)  if to a Holder of Registrable Securities, at the most current
     address given by the Trustee to the Company; and

            (ii) if to the Company, at 455 North Cityfront Plaza Drive, Chicago,
     Illinois, 60611, Attention:  Vice President and Treasurer and General
     Counsel; with a copy to Kirkland & Ellis, 200 East Randolph Drive, Chicago,
     Illinois, 60601, Attention:  Michael H. Kerr.

          All such notices and communications shall be deemed to have been duly
given:  when delivered by hand, if personally delivered; five business days
after being deposited in the mail, postage prepaid, if mailed; one business day
after being timely delivered to a next-day air courier; and when receipt is
acknowledged by the addressee, if telecopied.

          Copies of all such notices, demands or other communications shall be
concurrently delivered by the Person giving the same to the trustee under the
Indenture at the address specified in such Indenture.

          (f) Successors and Assigns.  This Agreement shall inure to the benefit
              ----------------------                                            
     of and be binding upon the successors and assigns of each of the parties,
     including without limitation and without the need for an express
     assignment, subsequent Holders of Registrable Securities; provided, that,
     with respect to the indemnity and contribution agreements in Section 7,
     each Holder of Registrable Securities subsequent to the Initial Purchasers
     shall be bound by the terms thereof if such Holder elects to include
     Registrable Securities in a Shelf Registration; provided, however, that
     this Agreement shall not inure to the benefit of or be binding upon a
     successor or assign of a Holder unless and to the extent such successor or
     assign holds Registrable Securities.

          (g) Counterparts.  This Agreement may be executed in any number of
              ------------                                                  
     counterparts and by the parties hereto in separate counterparts, each of
     which when so executed shall be deemed to be an original and all of which
     taken together shall constitute one and the same agreement.

          (h) Headings.  The headings in this Agreement are for convenience of
              --------

     IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO

     TO PRINCIPLES OF CONFLICTS OF LAW.  EACH OF THE PARTIES HERETO AGREES TO
     SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY
     ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

          (j) Severability.  If any term, provision, covenant or restriction of
              ------------                                                     
     this Agreement is held by a court of competent jurisdiction to be invalid,
     illegal, void or unenforceable, the remainder of the terms, provisions,
     covenants and restrictions set forth herein shall remain in full force and
     effect and shall in no way be affected, impaired or invalidated, and the
     parties hereto shall use their best efforts to find and employ an
     alternative means to achieve the same or substantially the same result as
     that contemplated by such term, provision, covenant or restriction.  It is

              ------------------------------------------------               
     consent or approval of holders of a specified percentage of Registrable
     Securities is required hereunder, Registrable Securities held by the

<PAGE>
 
                                      -2-

     The Company hereby agrees with the Initial Purchasers as follows:

     1.  The Company hereby agrees, upon the basis of your representations and
warranties contained in Section 2 hereof, to issue and sell the Securities to
the several Initial Purchasers as hereinafter provided, and each Initial
Purchaser, upon the basis of the representations and warranties herein
contained, but subject to the conditions hereinafter stated, agrees to purchase,
severally and not jointly, from the Company the respective principal amount of
Securities set forth opposite such Initial Purchaser's name in Schedule I hereto
at a price equal to 97.4200% of their principal amount (the "Purchase Price")
plus accrued interest, if any, from February 4, 1998.

     2.  The Company understands that the Initial Purchasers intend (x) to offer
privately the Securities as soon after this Agreement has become effective as in
the judgment of the Initial Purchasers is advisable and (y) initially to offer
the Securities upon the terms set forth in the Offering Memorandum (as defined
below).

     The Company confirms that it has authorized the Initial Purchasers, subject
to the restrictions set forth below, to distribute copies of the Offering
Memorandum in connection with the offering of the Securities.  Each Initial
Purchaser hereby makes to the Company the following representations, warranties
and covenants:

          (i)  it is a qualified institutional buyer within the meaning of Rule
     144A under the Securities Act; and

          (ii) (A) it will not solicit offers for, or offer to sell, the
     Securities by any form of general solicitation or general advertising (as
     those terms are used in Regulation D under the Securities Act) and (B) it
     will solicit offers for the Securities only from, and will offer the
     Securities only to, (1) persons whom it reasonably believes to be
     "qualified institutional buyers" within the meaning of Rule 144A under the
     Securities Act, or (2) upon the terms and conditions set forth in Annex I
     to this Agreement.

     3.  Payment for the Securities shall be made to the Company by wire
transfer in immediately available funds, to the account specified by the Company
to the Initial Purchasers at a bank reasonably acceptable to the Initial
Purchasers no later than noon the Business Day (as defined below) prior to the
Closing Date (as defined below), on February 4, 1998, or at such other time on
the same or such other date, not later than the fifth Business Day thereafter,
as the Initial Purchasers and the Company may agree upon in writing. The time
and date of such payment for the Securities are referred to herein as the
"Closing Date." As used herein, the term "Business Day" means any day other than
a day on which banks are permitted or required to be closed in New York City.
<PAGE>
 
                                      -3-

The Depository Trust Company for the account of the Initial Purchasers of one or
more global notes representing such Securities (collectively, the "Global
Notes"), with any transfer taxes payable in connection with the transfer to the
Initial Purchasers of the Securities duly paid by the Company.  The Global Notes
will be made available for inspection by the Initial Purchasers at the office of
J.P. Morgan Securities Inc. at the address set forth above not later than 1:00
P.M., New York City time, on the Business Day prior to the Closing Date.

     4.   The Company represents and warrants to each of the Initial Purchasers

     connection with the offering of the Securities. The Preliminary Offering
     Memorandum or the Offering Memorandum and any amendments or supplements
     thereto did not and will not, as of their respective dates, contain an
     untrue statement of a material fact or omit to state a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading, provided that
     this representation and warranty shall not apply to any statements or
     omissions made in reliance upon and in conformity with information relating
     to any Initial Purchaser furnished to the Company in writing by such
     Initial Purchaser expressly for use therein;

          (b)  the audited financial statements, and the related notes thereto,
     included in the Offering Memorandum present fairly the consolidated
     financial position of the Company and its subsidiaries and the results of
     their respective operations and the changes in their respective

     said financial statements have been prepared in conformity with generally
     accepted accounting principles applied on a consistent basis throughout the
     periods involved; the summary and selected financial and statistical data
     included in the Offering Memorandum present fairly the information shown
     therein and have been prepared and compiled on a basis consistent with the
     audited and unaudited financial statements of the Company, except as
     otherwise stated therein; and Deloitte & Touche LLP, who are reporting upon
     the audited consolidated financial statements of the Company and its
     consolidated subsidiaries (each a "Subsidiary," and collectively, the
     "Subsidiaries"), and the related schedules included in the Offering
     Memorandum, are independent public accountants as defined in the Securities
     Act;

          (c)  the Company owns, directly or indirectly, free and clear of any
     mortgage, pledge, security interest, lien, claim or other encumbrance or
     restriction on
<PAGE>
 
                                      -4-

     transferability or voting (other than as may be imposed by the Securities
     Act and the various state securities laws), all of the outstanding capital
     stock of each Subsidiary of the Company; all of the outstanding capital
     stock of each Subsidiary of the Company has been duly authorized and
     validly issued and is fully paid and non-assessable;

          (d)  since the respective dates as of which information is given in
     the Offering Memorandum there has not been (A) any change in the Company's
     issued capital stock, warrants or options except pursuant to the terms of
     the instruments governing the same or pursuant to the exercise of such
     options or warrants, or the issuance of certain options or (B) any material
     adverse change, or any development involving a prospective material adverse
     change, in or affecting the general affairs, the management, business,
     prospects, financial position, stockholder's equity or results of
     operations, of the Company and the Subsidiaries, taken as a whole (a

               (vii)  except as described in the Offering Memorandum, there is
          no action, suit or proceeding before or by any government,
          governmental instrumentality, agency, body or court, domestic or
          foreign, now pending or, to the best knowledge of such counsel after
          reasonable investigation, threatened against or affecting the Company
          or any of the Subsidiaries that could reasonably be expected to have a
          Material Adverse Effect or that could reasonably be expected to have a
          material adverse effect on the consummation of the transactions

          performance by the Company of all of the provisions of its obligations

          transactions contemplated therein and in the Offering Memorandum, do
          not and will not conflict with, or result in a breach or violation of
          any of the terms or provisions of, or constitute a default (or an
          event which, with notice or lapse of time, or both, would constitute a

          partnership agreement or other agreement or instrument known to such
          counsel after reasonable investigation to which the Company or any
          Subsidiary is a party or by which any of them may be bound or to which
          any of their respective properties or assets may be subject or (B) any
          judgment, order or decree of any government, governmental
          instrumentality, agency, body or court, domestic or foreign, having
          jurisdiction over the Company or any Subsidiary or any of their
          respective properties or assets known to such counsel after reasonable
          investigation except, with respect to clauses (A) and (B), any breach
          or violation that would not reasonably be expected to have a Material
          Adverse Effect.

                                     -15-

     Such counsel shall also advise, based on its participation in the
preparation of the Offering Memorandum and conferences with officers and
representatives of the Company, representatives of the independent public
accountants for the Company, representatives of the Initial Purchasers and
counsel to the Initial Purchasers, that nothing has come to its attention that
leads it to believe that the Offering Memorandum (as supplemented, if
applicable) (other than the financial statements, supporting schedules and other
financial and statistical data set forth therein, as to which no advice need be
given), as of its date or as of the Closing Date, contained or contains an
untrue statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

          (g)  on the date of the issuance of the Offering Memorandum and also
     on the Closing Date, Deloitte & Touche shall have furnished to the Initial
     Purchasers letters, dated the respective dates of delivery thereof, in form
     and substance satisfactory to the Initial Purchasers, containing statements
     and information of the type customarily included in accountants' "comfort
     letters" to underwriters with respect to the financial statements and
     certain financial information relating to the Company contained in the
     Offering Memorandum;

          (h)  the Company shall have executed and delivered the Registration
     Rights Agreement substantially in the form attached hereto as Annex II;

          (i)  the Initial Purchasers shall have received on and as of the
     Closing Date an opinion of Cahill Gordon & Reindel, counsel to the Initial
     Purchasers, with respect to the validity of the Indenture and the
     Securities, and such other related matters as the Initial Purchasers may
     reasonably request, and such counsel shall have received such papers and
     information as they may reasonably request to enable them to pass upon such
     matters;

          (j)  the Initial Purchasers shall have received on and as of the
     Closing Date a certificate dated the Closing Date and addressed to the
     Initial Purchasers signed by the Executive Vice President - Chief Financial
     Officer, Vice President and Treasurer of the Company or the Vice President
     and Controller to the effect that neither the Company nor any of its
     Subsidiaries is in breach or violation of any of the terms or provisions
     of, or with the giving of notice or lapse of time, or both, would be in
     default under any contract, indenture, mortgage, deed of trust, loan
     agreement, note, lease, partnership agreement, or other agreement or
     instrument to which the Company or any Subsidiary is a party or by which
     any of them may be bound or to which any of their respective properties or
     assets may be subject, except for any such breach or violation which would
     not have a Material Adverse Effect;
<PAGE>
 
                                     -16-

          (k)  on or prior to the Closing Date the Company shall have furnished
     to the Initial Purchasers such further certificates and documents as the
     Initial Purchasers or their counsel, Cahill Gordon & Reindel, shall
     reasonably request; and

          (l)  on or prior to the Closing Date the Company shall have furnished
     to the Initial Purchasers a duly executed waiver and amendment to the
     Mexico Credit Agreement (as defined in the Offering Memorandum) in form and
     substance satisfactory to them.

     7.   The Company agrees to indemnify and hold harmless each Initial
Purchaser, its officers and directors, and each person, if any, who controls any
Initial Purchaser within the meaning of either Section 15 of the Securities Act
or Section 20 of the Exchange Act, from and against any and all losses, claims,
damages and liabilities (including, without limitation, the reasonable legal
fees and other expenses incurred in connection with any suit, action or
proceeding or any claim asserted) caused by any untrue statement or alleged
untrue statement of a material fact contained in the Offering Memorandum (as
amended or supplemented if the Company shall have furnished any amendments or
supplements thereto) or any preliminary offering memorandum or caused by any
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 except insofar as such
losses, claims, damages or liabilities are caused by any untrue statement or
omission or alleged untrue statement or omission (i) made in reliance upon and
in conformity with information relating to the Initial Purchasers furnished to
the Company in writing by the Initial Purchasers expressly for use therein or
(ii) contained in the Preliminary Offering Memorandum if any Initial Purchaser
failed to send or deliver a copy of the Offering Memorandum to a U.S. person (as
defined in Regulation S) and who asserts such losses, claims, damages or
liabilities on or prior to the delivery of written confirmation of sale of the
Securities to such person and such Offering Memorandum would have corrected such
untrue statement or omission and it shall have been determined that such losses,
claims, damages or liabilities would not have arisen had the Offering Memorandum
been delivered or sent.

     Each Initial Purchaser agrees, severally and not jointly, to indemnify and
hold harmless the Company, its directors and officers and each person who
controls the Company within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act to the same extent as the foregoing indemnity
from the Company to each Initial Purchaser, but only with reference to
information relating to such Initial Purchaser furnished to the Company in
writing by such Initial Purchaser expressly for use in the Offering Memorandum,
any amendment or supplement thereto, or any preliminary offering memorandum.
For purposes of this Section 7 and paragraphs (a) and (b) of Section 4 hereof,
the only written information furnished by the Initial Purchasers to the Company
expressly for use in 
<PAGE>
 
                                     -17-

the Offering Memorandum is the information in the last paragraph of the cover
page of the Offering Memorandum, the fourth paragraph on page 2 of the Offering
Memorandum and the first, third, fifth, eighth and ninth paragraphs under the
caption in the "Plan of Distribution" section of the Offering Memorandum.

     If any suit, action, proceeding (including any governmental or regulatory
investigation), claim or demand shall be brought or asserted against any person
in respect of which indemnity may be sought pursuant to either of the two
preceding paragraphs, such person (the "Indemnified Person") shall promptly
notify the person against whom such indemnity may be sought (the "Indemnifying
Person") in writing, and the Indemnifying Person, upon request of the
Indemnified Person, shall retain counsel satisfactory to the Indemnified Person
to represent the Indemnified Person and any others the Indemnifying Person may
designate in such proceeding and shall pay the fees and expenses of such counsel
related to such proceeding.  In any such proceeding, any Indemnified Person
shall have the right to retain its own counsel, but the fees and expenses of
such counsel shall be at the expense of such Indemnified Person unless (i) the
Indemnifying Person and the Indemnified Person shall have mutually agreed to the
contrary, (ii) the Indemnifying Person has failed within a reasonable time to
retain counsel satisfactory to the Indemnified Person or (iii) the named parties
in any such proceeding (including any impleaded parties) include both the
Indemnifying Person and the Indemnified Person and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them.  It is understood that the Indemnifying Person
shall not, in connection with any proceeding or related proceeding in the same
jurisdiction, be liable for the reasonable fees and expenses of more than one
separate firm (in addition to any local counsel) for all Indemnified Persons,
and that all such reasonable fees and expenses shall be reimbursed as they are
incurred.  Any such separate firm for the Initial Purchasers and such control
persons of Initial Purchasers shall be designated in writing by J.P. Morgan
Securities Inc. and any such separate firm for the Company, its directors and
officers and such control persons of the Company shall be designated in writing
by the Company.  The Indemnifying Person shall not be liable for any settlement
of any proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the Indemnifying
Person agrees to indemnify any Indemnified Person from and against any loss or
liability by reason of such settlement or judgment.  Notwithstanding the
foregoing sentence, if at any time an Indemnified Person shall have requested an
Indemnifying Person to reimburse the Indemnified Person for fees and expenses of
counsel as contemplated by the third sentence of this paragraph, the
Indemnifying Person 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 days after receipt by such Indemnifying Person of the
aforesaid request and (ii) such Indemnifying Person shall not have reimbursed
the Indemnified Person in accordance with such request prior to the date of such
settlement (or delivered a notice to such Indem-
<PAGE>
 
                                     -18-

nified Person setting forth its good faith objection to such request's
conformity to the provisions of this Section 7). No Indemnifying Person shall,
without the prior written consent of the Indemnified Person, effect any
settlement of any pending or threatened proceeding in respect of which any
Indemnified Person is or could have been a party and indemnity could have been
sought hereunder by such Indemnified Person, unless such settlement includes an
unconditional written release, in form and substance reasonably satisfactory to
the Indemnified Person, of such Indemnified Person from all liability on claims
that are the subject matter of such proceeding.

     If the indemnification provided for in the first and second paragraphs of
this Section 7 is for any reason unavailable to, or insufficient to hold
harmless, an Indemnified Person in respect of any losses, claims, damages or
liabilities referred to therein, then each Indemnifying Person under such
paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall
contribute to the amount paid or payable by such Indemnified Person as a result
of such losses, claims, damages or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the Initial Purchasers on the other hand from the offering of the
Securities or (ii) if the allocation provided by clause (i) above 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 on the one hand and the Initial Purchasers on the other in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations.  The relative benefits received by the Company on the one hand
and the Initial Purchasers on the other shall be deemed to be in the same
respective proportions as the net proceeds from the offering (before deducting
expenses) received by the Company and the total discounts and the commissions
actually received by the Initial Purchasers, in each case as set forth in the
table on the cover of the Offering Memorandum, bear to the aggregate offering
price of the Securities.  The relative fault of the Company on the one hand and
the Initial Purchasers on the other 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 or by the Initial Purchasers and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

     The Company and the Initial Purchasers agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata
allocation (even if the Initial Purchasers were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
<PAGE>
 
                                     -19-

paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses incurred by such Indemnified Person in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7, in no event shall an Initial
Purchaser be required to contribute any amount in excess of the amount by which
the total price at which the Securities purchased by it were offered exceeds the
amount of any damages that such Initial Purchaser has otherwise been required to
pay or has paid by reason of such untrue or alleged untrue statement or omission
or alleged omission.  No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Initial Purchasers' obligations to contribute pursuant
to this Section 7 are several in proportion to the respective principal amounts
of Securities set forth opposite their names in Schedule I hereto, and not
joint.

     The indemnity and contribution agreements contained in this Section 7 are
in addition to any liability which the Indemnifying Persons may otherwise have
to the Indemnified Persons referred to above.

     The indemnity and contribution agreements contained in this Section 7 and
the representations and warranties of the Company as set forth in this Agreement
shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
any Initial Purchaser or any person controlling any Initial Purchaser or by or
on behalf of the Company, its officers or directors or any other person
controlling the Company and (iii) acceptance of and payment for any of the
Securities.

     8.  Notwithstanding anything herein contained, this Agreement may be
terminated in the absolute discretion of the Initial Purchasers, by notice given
to the Company, if after the execution and delivery of this Agreement and prior
to the Closing Date (i) trading generally shall have been suspended or
materially limited on or by, as the case may be, any of the New York Stock
Exchange, the American Stock Exchange or the National Association of Securities
Dealers, Inc., (ii) trading of any securities of or guaranteed by the Company
shall have been suspended on any exchange or in any over-the-counter market,
(iii) a general moratorium on commercial banking activities in New York shall
have been declared by either Federal or New York State authorities or (iv) there
shall have occurred any outbreak or escalation of hostilities or any change in
financial markets or any calamity or crisis that, in the judgment of the Initial
Purchasers, is material and adverse and which, in the judgment of the Initial
Purchasers, makes it impracticable or inadvisable to market the Securities on
the terms and in the manner contemplated in the Offering Memorandum.

     9.  This Agreement shall become effective upon the execution and delivery
hereof by the parties hereto.
<PAGE>
 
                                     -20-

     10.  If this Agreement shall be terminated by the Initial Purchasers
because of any failure or refusal on the part of the Company to comply with the
terms or to fulfill any of the conditions of this Agreement, or if for any
reason the Company shall be unable to perform its obligations under this
Agreement, the Company agrees to reimburse the Initial Purchasers for all 
out-of-pocket expenses (including the reasonable fees and expenses of their
counsel) reasonably incurred by the Initial Purchasers in connection with this
Agreement or the offering contemplated hereunder. The Company shall not be
obligated to reimburse the Initial Purchasers for any out-of-pocket expenses
reasonably incurred by the Initial Purchasers if this Agreement is terminated by
the Initial Purchasers pursuant to Section 8(i), (iii) and (iv) hereof.

     11.  This Agreement shall inure to the benefit of and be binding upon the
Initial Purchasers and the Company, any controlling person referred to herein
and their respective successors, heirs and legal representatives.  Nothing
expressed or mentioned in this Agreement is intended or shall be construed to
give any person, firm or corporation, other than the Initial Purchasers and the
Company and their respective successors, heirs and legal representatives and the
controlling persons and officers and directors referred to in Section 7 and
their heirs and legal representatives, any legal or equitable right, remedy or
claim under or in respect of this Agreement or any provision herein contained.
No purchaser of Securities from any Initial Purchaser shall be deemed to be a
successor merely by reason of such purchase.

     12.  Any action by the Initial Purchasers hereunder may be taken by the
Initial Purchasers jointly or by J.P. Morgan Securities Inc. alone or on behalf
of the Initial Purchasers, and any such action taken by J.P. Morgan Securities
Inc. alone shall be binding upon the Initial Purchasers. All notices and other
communications hereunder shall be in writing and shall be deemed to have been
duly given if mailed or transmitted by any standard form of telecommunication.
Notices to the Initial Purchasers shall be given to them at the following
address: J.P. Morgan Securities Inc., 60 Wall Street, New York, New York 10260;
Attention: Syndicate Department. Notices to the Company shall be given to it at
455 North Cityfront Plaza Drive, Chicago, Illinois 60611; Attention: Vice
President and Treasurer (facsimile (312) 836-2573) with a copy to the Company's
General Counsel at the same address.

     13.  This Agreement may be signed in counterparts, each of which shall be
an original (or a facsimile copy thereof) and all of which together shall
constitute one and the same instrument.

     14.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CONFLICTS OF
LAWS PROVISIONS THEREOF.

                                    ANNEX I

     (A) In addition to offers pursuant to clause (B)(1) of paragraph 2(ii) of
the Agreement, the Initial Purchasers intend to offer and sell the Securities in
accordance with Regulation S under the Securities Act.  Accordingly, each
Initial Purchaser agrees that neither it, its affiliates nor any persons acting
on its or their behalf has engaged or will engage in any directed selling
efforts with respect to the Securities and it and they have complied and will
comply with the offering restrictions requirement of Regulation S.  Each Initial
Purchaser agrees that, at or prior to confirmation of sale of Securities (other
than a sale pursuant to and in accordance with paragraph 2(ii) of the Agreement
to purchasers described in clause (B)(1) thereof), it will have sent to each
distributor, dealer or person receiving a selling concession, fee or other
remuneration that purchases Securities from it during the restricted period a
confirmation or notice to substantially the following effect:

          "The Securities covered hereby have not been registered under the U.S.
     Securities Act of 1933 (the "Act") and may not be offered and sold within
     the United States or to, or for the account or benefit of, U.S. persons (i)
     as part of their distribution at any time or (ii) otherwise until 40 days
     after the later of the commencement of the offering and the closing date,
     except in either case in accordance with Regulation S (or Rule 144A if
     available) under the Act.  Terms used above have the meaning given to them
     by Regulation S."

Terms used in this paragraph have the meanings given to them by Regulation S.

     Each of the Initial Purchasers further agrees that it has not entered and
will not enter into any contractual arrangement with respect to the distribution
or delivery of the Securities in accordance with this paragraph (A), except with
its affiliates or with the prior written consent of the Company.

     (B) Each of the Initial Purchasers severally represents and agrees that (i)
it has not offered or sold and prior to the date six months after the date of
issue of the Securities will not offer or sell any Securities to persons in the
United Kingdom except to persons whose ordinary activities involve them in
acquiring, holding, managing or disposing of investments (as principal or agent)
for the purposes of their business or otherwise in circumstances which have not
resulted and will not result in an offer to the public in the United Kingdom
within the meaning of the Public Offers of Securities Regulations 1995, (ii) it
has complied, and will comply with all applicable provisions of the Financial
Services Act 1986 and any regulation promulgated thereto of Great Britain with
respect to anything done by it in relation to the Securities in, from or
otherwise involving the United Kingdom, and (iii) it has only issued or passed
on and will only issue or pass on in the United Kingdom any 
<PAGE>
 
                                     AI-2

document received by it in connection with the issue of the Securities to a
person who is of a kind described in Article 11(3) of the Financial Services Act
1986 (Investment Advertisements) (Exemptions) Order 1996 or is a person to whom
such document may otherwise lawfully be issued or passed on.

     (C) Each of the Initial Purchasers agrees that it will not offer, sell or
deliver any of the Securities in any jurisdiction outside the United States
except under circumstances that will result in compliance with the applicable
laws thereof, and that it will take at its own expense whatever action is
required to permit its purchase and resale of the Securities in such
jurisdictions.  Each of the Initial Purchasers understands that no action has
been taken to permit a public offering in any jurisdiction outside the United
States where action would be required for such purposes.  Each of the Initial
Purchasers agrees not to cause any advertisement (other than an announcement of
the consummation of the offer and sale of the Securities) of the Securities to
be published in any newspaper or periodical or posted in any public place and
not to issue any circular relating to the Securities (other than the Offering
Memorandum).

2.  Exchange Offer
    --------------

          (a)  The Company agrees to file with the SEC as soon as practicable
     after the Closing Date, but in no event later than the Filing Date, an
     offer to exchange (the "Exchange Offer") any and all of the Registrable
     Securities for a like aggregate principal amount of debt securities of the
     Company which are identical in all material respects to the Notes (the
     "Exchange Securities") (and which are entitled to the benefits of a trust
     indenture which is identical in all material respects to the Indenture
     (other than such changes as are necessary to comply with any requirements
     of the SEC to effect or maintain the qualification of such trust indenture
     under the TIA) and which has been qualified under the TIA), except that the
     Exchange Securities shall have been registered pursuant to an effective
     Registration Statement under the Securities Act and shall contain no
     restrictive legend thereon. The Company agrees to use its reasonable best
     efforts to keep the Exchange Offer open for at least 20 
<PAGE>
 
                                      -5-

     business days (or longer if required by applicable law) after the date
     notice of the Exchange Offer is mailed to Holders and to consummate the
     Exchange Offer on or prior to the Effectiveness Date. The Exchange Offer
     will be registered under the Securities Act on the appropriate form (the
     "Exchange Registration Statement") and will comply with all applicable
     tender offer rules and regulations under the Exchange Act. If after such
     Exchange Registration Statement is initially declared effective by the SEC,
     the Exchange Offer or the issuance of the Exchange Securities thereunder is
     interfered with by any stop order, injunction or other order or requirement
     of the SEC or any other governmental agency or court such Exchange
     Registration Statement shall be deemed not to have become effective for
     purposes of this Agreement. Each Holder who participates in the Exchange
     Offer will be deemed to represent that any Exchange Securities received by
     it will be acquired in the ordinary course of its business, that at the
     time of the consummation of the Exchange Offer such Holder will have no
     arrangement with any person to participate in the distribution of the
     Exchange Securities in violation of the provisions of the Securities Act,
     and that such Holder is not an affiliate of the Company within the meaning
     of the Securities Act. Upon consummation of the Exchange Offer in
     accordance with this Section 2, the provisions of this Agreement shall
     continue to apply, mutatis mutandis, solely with respect to Registrable
                        ------- --------
     Securities that are Private Exchange Securities and Exchange Securities
     held by Participating Broker-Dealers, and the Company shall have no further
     obligation to register Registrable Securities (other than Private Exchange
     Securities and other than Exchange Securities as to which clause (c)(1)(i)
     hereof applies) pursuant to Section 3 of this Agreement. No securities
     other than the Exchange Securities (and the Company's 7% Senior Notes due
     2003) shall be included in the Exchange Registration Statement.

          (b)  The Company shall include within the Prospectus contained in the
     Exchange Registration Statement one or more section(s) reasonably
     acceptable to the Initial Purchasers, which shall contain a summary
     statement of the positions taken or policies made by the Staff of the SEC
     with respect to the potential "underwriter" status of any broker-dealer
     that is the beneficial owner (as defined in Rule 13d-3 under the Exchange
     Act) of Exchange Securities received by such broker-dealer in the Exchange
     Offer (a "Participating Broker-Dealer"), whether such positions or policies
     have been publicly disseminated by the Staff of the SEC or such positions
     or policies, in the reasonable judgment of the Initial Purchasers,
     represent the prevailing views of the Staff of the SEC. Such section(s)
     shall also allow the use of the prospectus by all persons subject to the
     prospectus delivery requirements of the Securities Act, including all
     Participating Broker-Dealers, and include a statement describing the means
     by which Participating Broker-Dealers may resell the Exchange Securities.
<PAGE>
 
                                      -6-

          The Company shall use its reasonable best efforts to keep the Exchange
     Registration Statement effective and to amend and supplement the Prospectus
     contained therein in order to permit such Prospectus to be lawfully
     delivered by all persons subject to the prospectus delivery requirements of
     the Securities Act for such period of time as such persons must comply with
     such requirements in order to resell the Exchange Securities, provided that
                                                                   --------     
     such period shall not exceed 180 days (or such longer period if extended
     pursuant to the last paragraph of Section 5) (the "Applicable Period").
     Notwithstanding the foregoing, the Company shall have no obligation to keep
     the Exchange Registration Statement effective or to amend and supplement
     the Prospectus contained therein in the event that the Company has not
     received written notice within 30 days following the completion of the
     Exchange Offer that a participating Broker-Dealer received Exchange
     Securities in the Exchange Offer.

          If, prior to consummation of the Exchange Offer, an Initial Purchaser
     holds any Notes acquired by it and having the status of an unsold allotment
     in the initial distribution, the Company upon the request of such Initial
     Purchaser shall, simultaneously with the delivery of the Exchange
     Securities in the Exchange Offer, issue and deliver to each such Initial
     Purchaser, in exchange (the "Private Exchange") for the Notes held by such
     Initial Purchaser, a like principal amount of debt securities of the
     Company that are identical in all material respects to the Exchange
     Securities (the "Private Exchange Securities") (and which are issued
     pursuant to the same indenture as the Exchange Securities) except for the
     placement of a  restrictive legend on such Private Exchange Securities.
     The Private Exchange Securities shall bear the same CUSIP number as the
     Exchange Securities.  Interest on the Exchange Securities and Private
     Exchange Securities will accrue from the last interest payment date on
     which interest was paid on the Notes surrendered in exchange therefor or,
     if no interest has been paid on the Notes, from the Issue Date.

          Any indenture under which the Exchange Securities or  the Private
     Exchange Securities will be issued shall provide that the holders of any of
     the Exchange Securities and the Private Exchange Securities will vote and
     consent together on all matters (to which such holders are entitled to vote
     or consent) as one class and that none of the holders of the Exchange
     Securities and the Private Exchange Securities will have the right to vote
     or consent as a separate class on any matter (to which such holders are
     entitled to vote or consent).

          (c)  If (1) prior to the consummation of the Exchange Offer, the
     Company reasonably determines in good faith or Holders of at least a
     majority in aggregate principal amount of the Registrable Securities notify
     the Company that they have reasonably determined in good faith that (i) in
     the opinion of counsel, the Exchange
<PAGE>
 
                                      -7-

     Securities would not, upon receipt, be tradeable by such Holders who are
     not affiliates of the Company without restriction under the Securities Act
     and without restrictions under applicable blue sky or state securities laws
     or (ii) in the opinion of counsel, the SEC is unlikely to permit the
     consummation of the Exchange Offer and/or (2) subsequent to the
     consummation of the Private Exchange, holders of at least a majority in
     aggregate principal amount of the Private Exchange Securities so request
     with respect to the Private Exchange Securities and/or (3) the Exchange
     Offer is commenced and not consummated prior to the 45th day following the
     Consummation Date for any reason, then the Company shall promptly deliver
     to the Holders and the Trustee notice thereof (the "Shelf Notice") and
     shall thereafter file an Initial Shelf Registration as set forth in Section
     3 (which only in the circumstances contemplated by clause (2) of this
     sentence will relate solely to the Private Exchange Securities) pursuant to
     Section 3. The parties hereto agree that, following the delivery of a Shelf
     Notice to the Holders of Registrable Securities (only in the circumstances
     contemplated by clauses (1) and/or (3) of the preceding sentence), the
     Company shall not have any further obligation to conduct the Exchange Offer
     or the Private Exchange under this Section 2.

3.    Shelf Registration
      ------------------
          If a Shelf Notice is delivered as contemplated by Section 2(c), then:

          (a)  Initial Shelf Registration.  The Company shall as promptly as
               --------------------------
     reasonably practicable prepare and file with the SEC a Registration
     Statement for an offering to be made on a continuous basis pursuant to Rule
     415 covering all of the Registrable Securities (the "Initial Shelf
     Registration"). If the Company shall have not yet filed an Exchange
     Registration Statement, the Company shall use its reasonable best efforts
     to file with the SEC the Initial Shelf Registration on or prior to the
     Filing Date. Otherwise, the Company shall use its reasonable best efforts
     to file with the SEC the Initial Shelf Registration within 60 days of the
     delivery of the Shelf Notice. The Initial Shelf Registration shall be on
     Form S-2 or S-3 or another appropriate form permitting registration of such
     Registrable Securities for resale by such holders in the manner or manners
     designated by them (including, without limitation, one or more underwritten
     offerings). The Company shall not permit any securities other than the
     Registrable Securities to be included in the Initial Shelf Registration or
     any Subsequent Shelf Registration. The Company shall use its reasonable
     best efforts to cause the Initial Shelf Registration to be declared
     effective under the Securities Act on or prior to the 120th day after the
     filing thereof with the SEC and to keep the Initial Shelf Registration
     continuously effective under the Securities Act until the date which is 24
     months from the Issue Date (subject to extension pursuant to the last
     paragraph of Section 5 hereof) (the "Effectiveness Period"), or such
<PAGE>
 
                                      -8-

     shorter period ending when (i) all Registrable Securities covered by the
     Initial Shelf Registration have been sold in the manner set forth and as
     contemplated in the Initial Shelf Registration or (ii) a Subsequent Shelf
     Registration covering all of the Registrable Securities has been declared
     effective under the Securities Act.

          (b)  Subsequent Shelf Registrations.  If the Initial Shelf
               ------------------------------
     Registration or any Subsequent Shelf Registration ceases to be effective
     for any reason at any time during the Effectiveness Period (other than
     because of the sale of all of the securities registered thereunder), the
     Company shall use its reasonable best efforts to obtain the prompt
     withdrawal of any order suspending the effectiveness thereof, and in any
     event shall within 45 days of such cessation of effectiveness amend the
     Shelf Registration in a manner reasonably expected to obtain the withdrawal
     of the order suspending the effectiveness thereof, or file an additional
     "shelf" Registration Statement pursuant to Rule 415 covering all of the
     Registrable Securities (a "Subsequent Shelf Registration"). If a Subsequent
     Shelf Registration is filed, the Company shall use its reasonable best
     efforts to cause the Subsequent Shelf Registration to be declared effective
     as soon as practicable after such filing and to keep such Registration
     Statement continuously effective for a period equal to the number of days
     in the Effectiveness Period less the aggregate number of days during which
     the Initial Shelf Registration or any Subsequent Shelf Registration was
     previously continuously effective. As used herein the term "Shelf
     Registration" means the Initial Shelf Registration and any Subsequent Shelf
     Registration.

          (c)  Supplements and Amendments.  The Company shall promptly
               --------------------------
     supplement and amend the Shelf Registration if required by the rules,
     regulations or instructions applicable to the registration form used for
     such Shelf Registration, if required by the Securities Act, or if
     reasonably requested by the Holders of a majority in aggregate principal
     amount of the Registrable Securities covered by such Registration Statement
     or by any underwriter of such Registrable Securities.

4.   Additional Interest
     -------------------

          (a)  The Company and the Initial Purchasers agree that the Holders of
     Registrable Securities will suffer damages if the Company fails to fulfill
     its obligations under Section 2 or Section 3 hereof and that it would not
     be feasible to ascertain the extent of such damages with precision.
     Accordingly, the Company agrees to pay, as liquidated damages, additional
     interest on the Registrable Securities ("Additional Interest") under the
     circumstances and to the extent set forth below (each of which shall be
     given independent effect and shall not be duplicative):
<PAGE>
 
                                      -9-

               (i)    if neither the Exchange Registration Statement nor the
     Initial Shelf Registration has been filed on or prior to the Filing Date,
     Additional Interest shall accrue on the Registrable Securities over and
     above the stated interest at a rate of .25% per annum for the first 90 days
     immediately following the Filing Date, such Additional Interest rate
     increasing by an additional .25% per annum at the beginning of each
     subsequent 90-day period;

               (ii)   if neither the Exchange Registration Statement nor the
     Initial Shelf Registration is declared effective by the SEC on or prior to
     the Effectiveness Date, Additional Interest shall accrue on the Registrable
     Securities included or which should have been included in such Registration
     Statement over and above the stated interest at a rate of .25% per annum
     for the first 90 days immediately following the day after the Effectiveness
     Date, such Additional Interest rate increasing by an additional .25% per
     annum at the beginning of each subsequent 90-day period; and

               (iii)  if (A) the Company has not exchanged Exchange Securities
     for all Notes validly tendered in accordance with the terms of the Exchange
     Offer on or prior to the Consummation Date or (B) the Exchange Registration
     Statement ceases to be effective at any time prior to the time that the
     Exchange Offer is consummated or (C) if applicable, the Shelf Registration
     has been declared effective and such Shelf Registration ceases to be
     effective at any time during the Effectiveness Period, then Additional
     Interest shall accrue on the Registrable Securities (over and above any
     interest otherwise payable on the Registrable Securities) at a rate of .25%
     per annum for the first 90 days commencing on the (x) 181st day after the
     Issue Date, in the case of (A) above, or (y) the day the Exchange
     Registration Statement ceases to be effective in the case of (B) above, or
     (z) the day such Shelf Registration ceases to be effective in the case of
     (C) above, such Additional Interest rate increasing by an additional .25%
     per annum at the beginning of each such subsequent 90-day period;

provided, however, that the Additional Interest rate on the Registrable
- --------  -------                                                      
Securities may not exceed at any one time in the aggregate 1.0% per annum; and
provided, further, that (1) upon the filing of the Exchange Registration
- --------  -------                                                       
Statement or a Shelf Registration as required hereunder (in the case of clause
(i) of this Section 4), (2) upon the effectiveness of the Exchange Registration
Statement or the Shelf Registration as required hereunder (in the case of clause
(ii) of this Section 4), or (3) upon the exchange of Exchange Securities for all
Notes tendered (in the case of clause (iii)(A) of this Section 4), or upon the
effectiveness of the Exchange Registration Statement which had ceased to remain
effective (in the case of (iii)(B) of this Section 4), or upon the effectiveness
of the Shelf Registration which had ceased to remain effective (in the case of
(iii)(C) of this Section 4), Additional Interest on the Registrable Securities
as a result of such clause (or the relevant subclause thereof), as the case may
be, shall cease to accrue.  It being understood and agreed that, 
<PAGE>
 
                                      -10-

notwithstanding any provision to the contrary, so long as any Registrable
Security is then covered by an effective Shelf Registration Statement, no
Additional Interest shall accrue on such Registrable Security.

          (b)  The Company shall notify the Trustee within one business day
     after each and every date on which an event occurs in respect of which
     Additional Interest is required to be paid (an "Event Date"). The Company
     shall pay the Additional Interest due on the Registrable Securities by
     depositing with the Trustee, in trust, for the benefit of the Holders
     thereof, on or before the applicable semi-annual interest payment date,
     immediately available funds in sums sufficient to pay the Additional
     Interest then due to Holders of Registrable Securities. The Additional
     Interest due shall be payable on each interest payment date to the record
     Holder of Registrable Securities entitled to receive the interest payment
     to be made on such date as set forth in the Indenture. The amount of
     Additional Interest will be determined by multiplying the applicable
     Additional Interest rate by the principal amount of the affected
     Registrable Securities of such Holders, multiplied by a fraction, the
     numerator of which is the number of days such Additional Interest rate was
     applicable during such period (determined on the basis of a 360-day year
     comprised of twelve 30-day months and, in the case of a partial month, the
     actual number of days elapsed), and the denominator of which is 360. Each
     obligation to pay Additional Interest shall be deemed to accrue immediately
     following the occurrence of the applicable Event Date. The parties hereto
     agree that the Additional Interest provided for in this Section 4
     constitutes a reasonable estimate of the damages that may be incurred by
     Holders of Registrable Securities by reason of the failure of a Shelf
     Registration or Exchange Offer to be filed or declared effective, or a
     Shelf Registration to remain effective, as the case may be, in accordance
     with this Section 4.

5.   Registration Procedures
     -----------------------

          In connection with the registration of any Registrable Securities
pursuant to Sections 2 or 3 hereof, the Company shall effect such registrations
to permit the sale of such Registrable Securities in accordance with the
intended method or methods of disposition thereof, and pursuant thereto the
Company shall:

          (a)  Use its reasonable best efforts to prepare and file with the SEC,
     as soon as practicable after the date hereof but in any event prior to the
     Filing Date in the case of the Exchange Registration Statement and the 45th
     day following the Consummation Date in the case of the Shelf Registration
     Statement, a Registration Statement or Registration Statements as
     prescribed by Section 2 or 3, and to use its reasonable best efforts to
     cause each such Registration Statement to become effective and remain
     effective as provided herein, provided that, if (1) such filing is pursuant
                                   --------

                                      -11-


     to Section 3, or (2) a Prospectus contained in an Exchange Registration
     Statement filed pursuant to Section 2 is required to be delivered under the
     Securities Act by any Participating Broker-Dealer who seeks to sell
     Exchange Securities during the Applicable Period, before filing any
     Registration Statement or Prospectus or any amendments or supplements
     thereto, the Company shall upon written request furnish to and afford the
     Holders of the Registrable Securities and each such Participating Broker-
     Dealer, as the case may be, covered by such Registration Statement, their
     counsel and the managing underwriters, if any, a reasonable opportunity to
     review copies of all such documents (including copies of any documents to
     be incorporated by reference therein and all exhibits thereto) proposed to
     be filed.

          (b)  Prepare and file with the SEC such amendments and post-effective
     amendments to each Shelf Registration or Exchange Registration Statement,
     as the case may be, as may be necessary to keep such Registration Statement
     continuously effective for the Effectiveness Period or the Applicable
     Period, as the case may be; cause the related Prospectus to be supplemented
     by any required Prospectus supplement, and as so supplemented to be filed
     pursuant to Rule 424 (or any similar provisions then in force) under the
     Securities Act; and comply with the provisions of the Securities Act, the
     Exchange Act and the rules and regulations of the SEC promulgated
     thereunder applicable to it with respect to the disposition of all
     securities covered by such Registration Statement as so amended or in such
     Prospectus as so supplemented and with respect to the subsequent resale of
     any securities being sold by a Participating Broker-Dealer covered by any
     such Prospectus; the Company shall not be deemed to have used its
     reasonable best efforts to keep a Registration Statement effective during
     the Applicable Period if the Company voluntarily takes any action that
     would result in selling Holders of the Registrable Securities covered
     thereby or Participating Broker-Dealers seeking to sell Exchange Securities
     not being able to sell such Registrable Securities or such Exchange
     Securities during that period unless such action is in the best interest of
     the Company (as determined by its board of directors), required by
     applicable law or unless the Company complies with this Agreement,
     including without limitation, the provisions of paragraph 5(k) hereof and
     the last paragraph of this Section 5.

          (c)  If (1) a Shelf Registration is filed pursuant to Section 3, or
     (2) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Securities
     during the Applicable Period, notify the selling Holders of Registrable
     Securities, or each such Participating Broker-Dealer, as the case may be,
     their counsel and the managing underwriters, if any, who have provided the
     Company with their names and addresses promptly (but in any event within
     two business days), and confirm such notice in writing, (i) when a
<PAGE>
 
                                      -12-

     Prospectus or any Prospectus supplement or post-effective amendment has
     been filed, and, with respect to a Registration Statement or any post-
     effective amendment, when the same has become effective under the
     Securities Act (including in such notice a written statement that any
     Holder may, upon request, obtain, without charge, one conformed copy of
     such Registration Statement or post-effective amendment including financial
     statements and schedules, documents incorporated or deemed to be
     incorporated by reference and exhibits), (ii) of the issuance by the SEC of
     any stop order suspending the effectiveness of a Registration Statement or
     of any order preventing or suspending the use of any preliminary prospectus
     or the initiation of any proceedings for that purpose, (iii) of the receipt
     by the Company of any notification with respect to the suspension of the
     qualification or exemption from qualification of a Registration Statement
     or any of the Registrable Securities or the Exchange Securities to be sold
     by any Participating Broker-Dealer for offer or sale in any jurisdiction,
     or the initiation or threatening of any proceeding for such purpose, (iv)
     of the happening of any event or any information becoming known that makes
     any statement made in such Registration Statement or related Prospectus or
     any document incorporated or deemed to be incorporated therein by reference
     untrue in any material respect or that requires the making of any changes
     in such Registration Statement, Prospectus or documents so that, in the
     case of the Registration Statement, 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 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, and (v) of the Company's reasonable determination that a post-
     effective amendment to a Registration Statement would be appropriate.

          (d)  If (1) a Shelf Registration is filed pursuant to Section 3, or
     (2) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Securities
     during the Applicable Period, use its reasonable best efforts to prevent
     the issuance of any order suspending the effectiveness of a Registration
     Statement or of any order preventing or suspending the use of a Prospectus
     or suspending the qualification (or exemption from qualification) of any of
     the Registrable Securities or the Exchange Securities to be sold by any
     Participating Broker-Dealer, for sale in any jurisdiction, and, if any such
     order is issued, to use its reasonable best efforts to obtain the
     withdrawal of any such order at the earliest possible moment.

          (e)  If a Shelf Registration is filed pursuant to Section 3 and if
     requested by the managing underwriters, if any, or the Holders of a
     majority in aggregate principal amount of the Registrable Securities being
     sold in connection with an underwritten offering, (i) promptly incorporate
     in a prospectus supplement or post-effective amendment such information as
     the managing underwriters, if any, or such Holders or counsel reasonably
     request to be included therein, or (ii) make all required filings of such
     prospectus supplement or such post-effective amendment as soon as
     practicable after the Company has received notification of the matters to
     be incorporated in such prospectus supplement or post-effective amendment.

          (f)  If (1) a Shelf Registration is filed pursuant to Section 3, or
     (2) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Securities
     during the Applicable Period, furnish to each selling Holder of Registrable
     Securities and to each such Participating Broker-Dealer who so requests and
     to counsel and each managing underwriter, if any, without charge, one
     conformed copy of the Registration Statement or Statements and each post-
     effective amendment thereto, including financial statements and schedules,
     and if requested, all documents incorporated or deemed to be incorporated
     therein by reference and all exhibits.

          (g)  If (1) a Shelf Registration is filed pursuant to Section 3, or
     (2) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Securities
     during the Applicable Period, deliver to each selling Holder of Registrable
     Securities, or each such Participating Broker-Dealer, as the case may be,
     their counsel, and the underwriters, if any, without charge, as many copies
     of the Prospectus or Prospectuses (including each form of preliminary
     prospectus) and each amendment or supplement thereto and any documents
     incorporated by reference therein as such Persons may reasonably request;
     and, subject to the last paragraph of this Section 5, the Company hereby
     consents to the use of such Prospectus and each amendment or supplement
     thereto by each of the selling holders of Registrable Securities or each
     such Participating Broker-Dealer, as the case may be, and the underwriters
     or agents, if any, and dealers (if any), in connection with the offering
     and sale of the Registrable Securities covered by or the sale by
     Participating Broker-Dealers of the Exchange Securities pursuant to such
     Prospectus and any amendment or supplement thereto.

          (h)  Prior to any public offering of Registrable Securities or any
     delivery of a Prospectus contained in the Exchange Registration Statement
     by any Participating Broker-Dealer who seeks to sell Exchange Securities
     during the Applicable Pe-

     such Registrable Securities for offer and sale under the securities or Blue
     Sky laws of such jurisdictions within the United States as any selling
     Holder, Participating Broker-Dealer, or the managing underwriters
     reasonably request in writing, provided that where Exchange Securities
                                    --------                    
     held by Participating Broker-Dealers or Registrable Securities are offered
     other than through an underwritten offering, the Company agrees to cause
     its counsel to perform Blue Sky investigations and file registrations and
     qualifications required to be filed pursuant to this Section 5(h); keep
     each such registration or qualification (or exemption therefrom) effective
     during the period such Registration Statement is required to be kept
     effective and do any and all other reasonable acts or things necessary or
     advisable to enable the disposition in such jurisdictions of the Exchange
     Securities held by Participating Broker-Dealers or the Registrable
     Securities covered by the applicable Registration Statement, provided that
                                                                  --------
     the Company shall not be required to (A) qualify generally to do business
     in any jurisdiction where it is not then so qualified, (B) take any action
     that would subject it to general service of process in any such

     reasonably cooperate with the selling Holders of Registrable Securities and
     the managing underwriters, if any, to facilitate the timely preparation and
     delivery of certificates representing Registrable 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 ("DTC"); and
     enable such Registrable Securities to be registered in such names as the
     managing underwriter or underwriters, if any, or Holders may request.

          (j)  Use its reasonable best efforts to cause the Registrable
     Securities covered by the Registration Statement to be registered with or
     approved by such other United States governmental agencies or authorities
     of the United States as may be necessary to enable the seller or sellers
     thereof or the underwriters, if any, to consummate the disposition of such
     Registrable Securities, except as may be required solely as a consequence
     of the nature of such selling Holder's business, in which case the Company
     will cooperate in all reasonable respects with the filing of such
     Registration Statement and the granting of such approvals.

          (k)  If (1) a Shelf Registration is filed pursuant to Section 3, or
     (2) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2
<PAGE>
 
                                      -15-

     is required to be delivered under the Securities Act by any
     Participating Broker-Dealer who seeks to sell Exchange Securities during
     the Applicable Period, upon the occurrence of any event contemplated by
     paragraph 5(c)(iv) or 5(c)(v) above, as promptly as practicable prepare and

     the Company, a supplement or post-effective amendment to the Registration
     Statement or a supplement to the related Prospectus or any document
     incorporated or deemed to be incorporated therein by reference, or file any
     other required document so that, as thereafter delivered to the purchasers
     of the Registrable Securities being sold thereunder or to the purchasers of
     the Exchange Securities to whom such Prospectus will be delivered by a
     Participating Broker-Dealer, any such Prospectus will not contain an untrue
     statement of a material fact or omit to state 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.

          (l)  Use its reasonable best efforts to cause the Registrable
     Securities covered by a Registration Statement or the Exchange Securities,
     as the case may be, to be rated with the appropriate rating agencies, if so
     requested by the Holders of a majority in aggregate principal amount of
     Registrable Securities covered by such Registration Statement or the
     Exchange Securities, as the case may be, or the managing underwriters, if
     any.

          (m)  Prior to the effective date of the first Registration Statement
     relating to the Registrable Securities, (i) provide the Trustee with
     printed certificates for the Registrable Securities in a form eligible for
     deposit with DTC and (ii) provide a CUSIP number for the Registrable
     Securities. (n) Use its best efforts to cause all Registrable Securities
     covered by such Registration Statement or the Exchange Securities, as the
     case may be, to be (i) listed on each securities exchange, if any, on which
     similar securities issued by the Company are then listed, or (ii)
     authorized to be quoted on the Nasdaq Stock Market's National Market if
     similar securities of the Company are so authorized.

          (n)  Use its best efforts to cause all Registrable Securities covered 
     by such Registration Statement or the Exchange Securities, as the case may 
     be, to be (i) listed on each securities exchange, if any, on which similar 
     securities issued by the Company are then listed, or (ii) authorized to be 
     quoted on the Nasdaq Stock Market's National Market if similar securities 
     of the Company are so authorized.

          (o)  In connection with an underwritten offering of Registrable
     Securities pursuant to a Shelf Registration, enter into an underwriting
     agreement as is customary in underwritten offerings and take all such other

     issuers to underwriters in underwritten offerings, and confirm the same if
     and when requested; (ii) obtain an opinion of counsel to the Company and
     updates thereof in form and substance reasonably satisfactory to the
     managing underwriters, addressed to the underwriters covering the matters
     customarily covered in opinions requested in underwritten offerings and
     such other matters as may be reasonably requested by underwriters; (iii)
     obtain "cold comfort" letters and updates thereof in form and substance
     reasonably satisfactory to the managing underwriters from the independent
     certified public accountant(s) 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 for which financial statements
     and financial data are, or are required to be, included in the Registration
     Statement), addressed to each of the underwriters, such letters to be in
     customary form and covering matters of the type customarily covered in
     "cold comfort" letters in connection with underwritten offerings and such
     other matters as may be reasonably requested by underwriters; and (iv) if
     an underwriting agreement is entered into, the same shall contain
     indemnification provisions and procedures no less favorable than those set
     forth in Section 7 hereof (or such other provisions and procedures
     acceptable to Holders of a majority in aggregate principal amount of
     Registrable Securities covered by such Registration Statement and the
     managing underwriters or agents) with respect to all parties to be
     indemnified pursuant to said Section. The above shall be done at each
     closing under such underwriting agreement, or as and to the extent required
     thereunder.

          (p)  If (1) a Shelf Registration is filed pursuant to Section 3, or
     (2) a Prospectus contained in an Exchange Registration Statement filed
     pursuant to Section 2 is required to be delivered under the Securities Act
     by any Participating Broker-Dealer who seeks to sell Exchange Securities
     during the Applicable Period, make available for inspection by any selling
     Holder of such Registrable Securities being sold, or each such
     Participating Broker-Dealer, as the case may be, any underwriter
     participating in any such disposition of Registrable Securities, if any,
     and any attorney, accountant or other agent retained by any such selling
     holder or each such Participating Broker-Dealer, as the case may be, or
     underwriter (collectively, the "Inspectors"), at the offices where normally
     kept, during reasonable business hours, all financial and other records,
     pertinent corporate documents and properties of the Company and its
     subsidiaries (collectively, the "Records"), as shall be reasonably
     necessary to enable them to exercise any applicable due diligence
     responsibilities, and cause the officers, directors and employees of the
     Company to supply all information in each case reasonably requested by any
     such Inspector in connection with such Registration Statement. Records
     determined in good faith by the
<PAGE>
 
                                      -17-

     Company to be confidential shall not be disclosed by any Inspector notified
     of such determination unless (i) the disclosure of such Records is
     necessary to avoid or correct a misstatement or omission in such
     Registration Statement, (ii) the release of such Records is ordered
     pursuant to a subpoena or other order from a court of competent
     jurisdiction or (iii) the information in such Records has been made
     generally available to the public. Each selling Holder of such Registrable
     Securities and each such Participating Broker-Dealer will be required to
     agree that information obtained by it as a result of such inspections shall
     be deemed confidential and shall not be used by it as the basis for any
     market transactions in the securities of the Company unless and until such
     is made generally available to the public. Each selling Holder of such
     Registrable Securities and each such Participating Broker-Dealer will be
     required to further agree that it will, upon learning that disclosure of
     such Records is sought in a court of competent jurisdiction, give notice to
     the Company and allow the Company at its expense to undertake appropriate
     action to prevent disclosure of the Records deemed confidential.

          (q)  Provide an indenture trustee for the Registrable Securities or
     the Exchange Securities, as the case may be, and cause the Indenture or the
     trust indenture provided for in Section 2(a), as the case may be, to be
     qualified under the TIA not later than the effective date of the Exchange
     Offer or the first Registration Statement relating to the Registrable
     Securities; and in connection therewith, cooperate with the trustee under
     any such indenture and the holders of the Registrable Securities, to effect
     such changes to such indenture as may be required for such indenture to be
     so qualified in accordance with the terms of the TIA; and execute, and use
     its reasonable best efforts to cause such trustee to execute, all documents
     as may be required to effect such changes, and all other forms and
     documents required to be filed with the SEC to enable such indenture to be
     so qualified in a timely manner.

          (r)  Comply in all material respects with all applicable rules and
     regulations of the SEC and make generally available to its securityholders
     earning statements satisfying the provisions of Section 11(a) of the
     Securities Act and Rule 158 thereunder (or any similar rule promulgated
     under the Securities Act) no later than 90 days after the end of any 12-
     month period (i) commencing at the end of any fiscal quarter in which
     Registrable Securities are sold to underwriters in a firm commitment or
     best efforts underwritten offering and (ii) if not sold to underwriters in
     such an offering, commencing on the first day of the first fiscal quarter
     of the Company after the effective date of a Shelf Registration Statement,
     which statements shall cover said 12-month periods.

          (s)  If an Exchange Offer or a Private Exchange is to be consummated,
     upon delivery of the Registrable Securities by Holders to the Company (or
     to such
<PAGE>
 
                                      -18-

     other Person as directed by the Company) in exchange for the Exchange
     Securities or the Private Exchange Securities, as the case may be, the
     Company shall mark, or caused to be marked, on such Registrable Securities
     that such Registrable Securities are being cancelled in exchange for the
     Exchange Securities or the Private Exchange Securities, as the case  may
     be; in no event shall such Registrable Securities be marked as paid or
     otherwise satisfied.

          (t)  Reasonably cooperate with each seller of Registrable Securities
     covered by any Registration Statement and each underwriter, if any,
     participating in the disposition of such Registrable Securities and their
     respective counsel in connection with any filings required to be made with
     the National Association of Securities Dealers, Inc. (the "NASD").

          (u)  The Company will use its best efforts to (i) if the Registrable
     Securities have been rated prior to the initial sale of such Registrable
     Securities, confirm such ratings will apply to the Registrable Securities
     covered by a Registration Statement or (ii) if the Registrable Securities
     were not previously rated, cause the Registrable Securities covered by a
     Registration Statement to be rated with the appropriate rating agencies, if
     so requested by Holders of a majority in aggregate principal amount of the
     Registrable Securities covered by such Registration Statement, or by the
     managing underwriters, if any.

          (v)  Use its reasonable best efforts to take all other steps necessary
     to effect the registration of the Registrable Securities covered by a
     Registration Statement contemplated hereby.

          The Company may require each seller of Registrable Securities or
Participating Broker-Dealer as to which any registration is being effected to
furnish to the Company such information regarding such seller or Participating
Broker-Dealer and the distribution of such Registrable Securities or Exchange
Securities to be sold by such Participating Broker-Dealer, as the case may be,
as the Company may, from time to time, reasonably request.  The Company may
exclude from such registration the Registrable Securities of any seller or
Participating Broker-Dealer who unreasonably fails to furnish such information
within a reasonable time after receiving such request.  Each seller as to which
any Shelf Registration is being effected is deemed to agree to furnish promptly
to the Company all information required to be disclosed in order to make the
information previously furnished to the Company by such seller not materially
misleading.

          Each Holder of Registrable Securities and each Participating Broker-
Dealer agrees by acquisition of such Registrable Securities or Exchange
Securities to be sold by such Participating Broker-Dealer, as the case may be,
that, upon receipt of any notice from 
<PAGE>
 
                                      -19-

the Company of the happening of any event of the kind described in Section
5(c)(ii), 5(c)(iii), 5(c)(iv), or 5(c)(v), such Holder will forthwith
discontinue disposition of such Registrable Securities covered by such
Registration Statement or Prospectus or Exchange Securities to be sold by such
Participating Broker-Dealer, as the case may be, until such holder's receipt of
the copies of the supplemented or amended Prospectus contemplated by Section
5(k), or until it is advised in writing (the "Advice") by the Company that the
use of the applicable Prospectus may be resumed, and has received copies of any
amendments or supplements thereto. In the event the Company shall give any such
notice, each of the Effectiveness Period and the Applicable Period shall be
extended by the number of days during such periods from and including the date
of the giving of such notice to and including the date when each seller of
Registrable Securities covered by such Registration Statement or Exchange
Securities to be sold by such Participating Broker-Dealer, as the case may be,
shall have received (x) the copies of the supplemented or amended Prospectus
contemplated by Section 5(k) or (y) the Advice.

6.   Registration Expenses
     ---------------------

          (a)  All fees and expenses incident to the performance of or
     compliance with this Agreement by the Company shall be borne by the Company
     whether or not the Exchange Offer or a Shelf Registration is filed or
     becomes effective, including, without limitation, (i) all registration and
     filing fees (including, without limitation, (A) fees with respect to
     filings required to be made with the NASD in connection with an
     underwritten offering and (B) fees and expenses of compliance with state
     securities or Blue Sky laws (including, without limitation, reasonable fees
     and disbursements of counsel in connection with Blue Sky qualifications of
     the Registrable Securities or Exchange Securities and determination of the
     eligibility of the Registrable Securities or Exchange Securities for
     investment under the laws of such jurisdictions in the United States (x)
     where the holders of Registrable Securities are located, in the case of the
     Exchange Securities, or (y) as provided in Section 5(h), in the case of
     Registrable Securities or Exchange Securities to be sold by a Participating
     Broker-Dealer during the Applicable Period)), (ii) printing expenses
     (including, without limitation, expenses of printing certificates for
     Registrable Securities or Exchange Securities in a form eligible for
     deposit with DTC and of printing prospectuses if the printing of
     prospectuses is requested by the managing underwriters, if any, or, in
     respect of Registrable Securities or Exchange Securities to be sold by any
     Participating Broker-Dealer during the Applicable Period, by the Holders of
     a majority in aggregate principal amount of the Registrable Securities
     included in any Registration Statement or of such Exchange Securities, as
     the case may be), (iii) messenger, telephone and delivery expenses, (iv)
     reasonable fees and disbursements of counsel for the Company and fees and
     disbursements of special counsel for the sellers of Registrable Securities
     (subject to the provisions of Section 6(b)),
<PAGE>
 
                                      -20-

     (v) fees and disbursements of all independent certified public accountants
     referred to in Section 5(o)(iii) (including, without limitation, the
     expenses of any special audit and "cold comfort" letters required by or
     incident to such performance), (vi) rating agency fees, (vii) Securities
     Act liability insurance, if the Company desires such insurance, (viii) fees
     and expenses of all other Persons retained by the Company, (ix) internal
     expenses of the Company (including, without limitation, all salaries and
     expenses of officers and employees of the Company performing legal or
     accounting duties), (x) the expense of any annual audit, (xi) the fees and
     expenses incurred in connection with the listing of the securities to be
     registered on any securities exchange, if applicable, and (xii) the
     expenses relating to printing, word processing and distributing all
     Registration Statements, underwriting agreements, securities sales
     agreements, indentures and any other documents necessary in order to comply
     with this Agreement. In the event of an underwritten offering of
     Registrable Securities the Company shall not be responsible for any
     "roadshow expenses" in connection therewith except for those of its
     officers and directors in attending roadshow presentations.

          (b)  In connection with any Shelf Registration hereunder, the Company
     shall reimburse the Holders of the Registrable Securities being registered
     in such registration for the reasonable fees and disbursements of not more
     than one counsel (in addition to appropriate local counsel) chosen by the
     Holders of a majority in aggregate principal amount of the Registrable
     Securities to be included in such Registration Statement. Such Holders
     shall be responsible for any and all other out-of-pocket expenses of the
     Holders of Registrable Securities incurred in connection with the
     registration of the Registrable Securities.

7.   Indemnification
     ---------------

          The Company agrees to indemnify and hold harmless each Holder of
Registrable Securities if a Shelf Registration is filed pursuant to Section 3
and each Participating Broker-Dealer selling Exchange Securities during the
Applicable Period, the officers and directors of each such person, and each
person, if any, who controls any such person within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act (each, a
"Participant"), from and against any and all losses, claims, damages and
liabilities (including, without limitation, the legal fees and other expenses
incurred in connection with any suit, action or proceeding or any claim
asserted) caused by any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement (or any amendment thereto)
or Prospectus (as amended or supplemented if the Company shall have furnished
any amendments or supplements thereto) or any preliminary prospectus, or caused
by any 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 
<PAGE>
 
                                      -21-

under which they were made, not misleading, except insofar as such losses,
claims, damages or liabilities are caused by any untrue statement or omission or
alleged untrue statement or omission made in reliance upon and in conformity
with information relating to any Participant furnished to the Company in writing
by such Participant expressly for use therein; provided that the foregoing
                                               --------         
indemnity with respect to any preliminary prospectus shall not inure to the
benefit of any Participant (or to the benefit of any person controlling such
Participant) from whom the person asserting any such losses, claims, damages or
liabilities purchased Registrable Securities or Exchange Securities if such
untrue statement or omission or alleged untrue statement or omission made in
such preliminary prospectus is completely remedied in the related Prospectus (as
amended or supplemented if the Company shall have furnished any amendments or
supplements thereto) and a copy of the related Prospectus (as so amended or
supplemented) shall not have been furnished to such person at or prior to the
sale of such Registrable Securities or Exchange Securities, as the case may be,
to such person, if required by law.

          Each Participant will be required to agree, severally and not jointly,
to indemnify and hold harmless the Company, its directors, its officers and each
person who controls the Company within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to each Participant, but only with
reference to information relating to such Participant furnished to the Company
in writing by such Participant expressly for use in any Registration Statement
or Prospectus, any amendment or supplement thereto, or any preliminary
prospectus.  The liability of any Participant under this paragraph shall in no
event exceed the proceeds received by such Participant from sales of Registrable
Securities giving rise to such obligations.

          If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, such person (the "Indemnified Person") shall promptly
notify the person against whom such indemnity may be sought (the "Indemnifying
Person") in writing, and the Indemnifying Person, upon request of the
Indemnified Person, shall retain counsel satisfactory to the Indemnified Person
to represent the Indemnified Person and any others the Indemnifying Person may
designate in such proceeding and shall pay the fees and expenses of such counsel
related to such proceeding.  In any such proceeding, any Indemnified Person
shall have the right to retain its own counsel, but the fees and expenses of
such counsel shall be at the expense of such Indemnified Person unless (i) the
Indemnifying Person and the Indemnified Person shall have mutually agreed to the
contrary, (ii) the Indemnifying Person has failed within a reasonable time to
retain counsel satisfactory to the Indemnified Person or (iii) the named parties
in any such proceeding (including any impleaded parties) include both the
Indemnifying Person and the Indemnified Person and representation of both
parties by the 
<PAGE>
 
                                      -22-

same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood that the Indemnifying Person shall not,
in connection with any proceeding or related proceeding in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all Indemnified Persons, and that all
such fees and expenses shall be reimbursed as they are incurred. Any such
separate firm for the Participants and such control persons of Participants
shall be designated in writing by Participants who sold a majority in interest
of Registrable Securities sold by all such Participants and any such separate
firm for the Company, its directors, officers and such control persons of the
Company shall be designated in writing by the Company. The Indemnifying Person
shall not be liable for any settlement of any proceeding effected without its
written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, the Indemnifying Person agrees to indemnify any
Indemnified Person from and against any loss or liability by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an Indemnified Person shall have requested an Indemnifying Person to reimburse
the Indemnified Person for fees and expenses actually incurred by counsel as
contemplated by the third sentence of this paragraph, the Indemnifying Person
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
days after receipt by such Indemnifying Person of the aforesaid request and (ii)
such Indemnifying Person shall not have reimbursed the Indemnified Person in
accordance with such request prior to the date of such settlement (or delivered
a notice to such Indemnified Person setting forth its good faith objection to
such request's conformity to the provisions of this Section 7). No Indemnifying
Person shall, without the prior written consent of the Indemnified Person,
effect any settlement of any pending or threatened proceeding in respect of
which any Indemnified Person is or could have been a party and indemnity could
have been sought hereunder by such Indemnified Person, unless such settlement
includes an unconditional written release in form and substance satisfactory to
the Indemnified Person, of such Indemnified Person from all liability on claims
that are the subject matter of such proceeding.

          If the Indemnification provided for in the first and second paragraphs
of this Section 7 is unavailable to, or insufficient to hold harmless, an
Indemnified Person in respect of any losses, claims, damages or liabilities
referred to therein, then each Indemnifying Person under such paragraph, in lieu
of indemnifying such Indemnified Person thereunder, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect
the relative fault of the Company on the one hand and the Participants on the
other in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations.  The relative fault of the Company on the one hand and the
Participants on the other shall be determined by refer-
<PAGE>
 
                                      -23-

ence 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 or by the Participants and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

          The parties shall agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
                                                           --- ----           
(even if the Participants were treated as one entity for such purpose) or by any
other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph.  The amount
paid or payable by an Indemnified Person as a result of the losses, claims,
damages and liabilities referred to in the immediately preceding paragraph shall
be deemed to include, subject to the limitations set forth above, any legal or
other expenses incurred by such Indemnified Person in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section 7, in no event shall a Participant be required to
contribute any amount in excess of the amount by which proceeds received by such
Participant from sales of Registrable Securities exceeds the amount of any
damages that such Participant has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission.  No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          The indemnity and contribution agreements contained in this Section 7
will be in addition to any liability which the Indemnifying Persons may
otherwise have to the Indemnified Persons referred to above.

8.   Rule 144 and Rule 144A
     ----------------------

          The Company covenants that it will file the reports required to be
filed by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the SEC thereunder in a timely manner and, if at any time
the Company is not required to file such reports, it will, upon the request of
any Holder of Registrable Securities, within a reasonable time period make
publicly available other information so long as necessary to permit sales
pursuant to Rule 144 and Rule 144A under the Securities Act.  The Company
further covenants that it will take such further action as any Holder of
Registrable Securities may reasonably request, all to the extent required from
time to time to enable such holder to sell Registrable Securities without
registration under the Securities Act within the limitation of the exemptions
provided by (a) Rule 144 and Rule 144A under the Securities Act, as such Rules
may be amended from time to time, or (b) any similar rule or regulation
hereafter adopted by the SEC.

                                      -24-

9.   Underwritten Registrations
     --------------------------

          Nothing in this Agreement shall be interpreted so as to obligate the
Company to participate in an underwritten offering of the Registrable Securities
covered by any Shelf Registration.  The Company's decision as to whether to
cooperate with a proposed underwritten offering shall be at its sole discretion.

          If any of the Registrable Securities covered by any Shelf Registration
are to be sold in an underwritten offering, the investment banker or investment
bankers and manager or managers that will manage the offering will be selected
by the Holders of a majority in aggregate principal amount of such  Registrable
Securities included in such offering and be reasonably acceptable to the
Company.

          No Holder of Registrable Securities may participate in any
underwritten registration hereunder unless such Holder (a) agrees to sell such
Holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements.

10.  Miscellaneous
     -------------

          (a)  Remedies.  In the event of a breach by the Company of any of its
               --------                                                        
     obligations under this Agreement, each Holder of Registrable Securities, in
     addition to being entitled to exercise all rights provided herein, in the
     Indenture or, in the case of the Initial Purchasers, in the Purchase
     Agreement or granted by law, including recovery of damages, will be
     entitled to specific performance of its rights under this Agreement.  The
     Company agrees that monetary damages would not be adequate compensation for
     any loss incurred by reason of a breach by it of any of the provisions of
     this Agreement and hereby further agree that, in the event of any action
     for specific performance in respect of such breach, the Company shall waive
     the defense that a remedy at law would be adequate.

          (b)  No Inconsistent Agreements.  The Company has not, as of the date 
               --------------------------   
     hereof, entered and shall not, after the date of this Agreement, enter into
     any agreement with respect to any of its securities that is inconsistent
     with the rights granted to the Holders of Registrable Securities in this
     Agreement or otherwise conflicts with the provisions hereof. The Company
     has not entered and will not enter into any agreement with respect to any
     of its securities which will grant to any Person piggy-back rights with
     respect to a Registration Statement.
<PAGE>
 
                                      -25-

          (c)  Adjustments Affecting Registrable Securities.  The Company shall
               --------------------------------------------     
     not, directly or indirectly, take any action with respect to the
     Registrable Securities as a class that would adversely affect the ability
     of the Holders of Registrable Securities to include such Registrable
     Securities in a registration undertaken pursuant to this Agreement.

          (d)  Amendments and Waivers.  The provisions of this Agreement, 
               ----------------------      
     including the provisions of this sentence, may not be amended, modified or
     supplemented, and waivers or consents to departures from the provisions
     hereof may not be given, unless the Company has obtained the written
     consent of Holders of at least a majority of the then outstanding aggregate
     principal amount of Registrable Securities. Notwithstanding the foregoing,
     a waiver or consent to depart from the provisions hereof with respect to a
     matter that relates exclusively to the rights of Holders of Registrable
     Securities whose securities are being sold pursuant to a Registration
     Statement and that does not directly or indirectly affect, impair, limit or
     compromise the rights of other Holders of Registrable Securities may be
     given by Holders of at least a majority in aggregate principal amount of
     the Registrable Securities being sold by such Holders pursuant to such
     Registration Statement, provided that the provisions of this sentence may
                             --------
     not be amended, modified or supplemented except in accordance with the
     provisions of the immediately preceding sentence.

          (e)  Notices.  All notices and other communications (including without
               -------                                                          
     limitation any notices or other communications to the Trustee) provided for
     or permitted hereunder shall be made in writing by hand-delivery,
     registered first-class mail, next-day air courier or telecopier:

          (i)  if to a Holder of Registrable Securities, at the most current
     address given by the Trustee to the Company; and

          (ii) if to the Company, at 455 North Cityfront Plaza Drive, Chicago,
     Illinois, 60611, Attention: Vice President and Treasurer and General
     Counsel; with a copy to Kirkland & Ellis, 200 East Randolph Drive, Chicago,
     Illinois, 60601, Attention: Michael H. Kerr.

          All such notices and communications shall be deemed to have been duly
given:  when delivered by hand, if personally delivered; five business days
after being deposited in the mail, postage prepaid, if mailed; one business day
after being timely delivered to a next-day air courier; and when receipt is
acknowledged by the addressee, if telecopied.
<PAGE>
 
                                      -26-

          Copies of all such notices, demands or other communications shall be
concurrently delivered by the Person giving the same to the trustee under the
Indenture at the address specified in such Indenture.

          (f)  Successors and Assigns.  This Agreement shall inure to the 
               ---------------------- 
     benefit of and be binding upon the successors and assigns of each of the
     parties, including without limitation and without the need for an express
     assignment, subsequent Holders of Registrable Securities; provided, that,
     with respect to the indemnity and contribution agreements in Section 7,
     each Holder of Registrable Securities subsequent to the Initial Purchasers
     shall be bound by the terms thereof if such Holder elects to include
     Registrable Securities in a Shelf Registration; provided, however, that
     this Agreement shall not inure to the benefit of or be binding upon a
     successor or assign of a Holder unless and to the extent such successor or
     assign holds Registrable Securities.

          (g)  Counterparts.  This Agreement may be executed in any number of 
               ------------   
     counterparts and by the parties hereto in separate counterparts, each of
     which when so executed shall be deemed to be an original and all of which
     taken together shall constitute one and the same agreement.
     
          (h)  Headings.  The headings in this Agreement are for convenience of

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

Ladies and Gentlemen:

     We are acting as special counsel to Navistar International Corporation, a
Delaware corporation (the "Company"), in connection with the proposed
registration by the Company of up to $100,000,000 in aggregate principal amount
of the Company's Series B 7% Senior Notes due 2003 (the "Senior Exchange Notes")
and up to $250,000,000 in aggregate principal amount of the Company's Series B
8% Senior Subordinated Notes due 2008 (the "Senior Subordinated Exchange Notes"
and together with the Senior Exchange Notes, the "Exchange Notes"), pursuant to
a Registration Statement on Form S-4, filed with the Securities and Exchange
Commission (the "Commission") on February 27, 1998 under the Securities Act of
1933, as amended (the "Securities Act") (such Registration Statement, as amended
or supplemented, is hereinafter referred to as the "Registration Statement"),
for the purpose of effecting an exchange offer (the "Exchange Offer") for the
Company's 7% Senior Notes due 2003 and 8% Senior Subordinated Notes due 2008
(collectively, the "Old Notes"). The Senior Exchange Notes are to be issued
pursuant to an Indenture (the "Senior Notes Indenture"), dated as of January 30,
1998, among the Company and Harris Trust and Savings Bank, as Trustee, and the
Senior Subordinated Exchange Notes are to be issued pursuant to an Indenture
(the "Senior Subordinated Notes Indenture" and together with the Senior Notes
Indenture, the "Indentures") among the Company and Harris Trust and Saving
Banks, as Trustee.

     In that connection, we have examined originals, or copies certified or
otherwise identified to our satisfaction, of such documents, corporate records
and other instruments as we have deemed necessary for the purposes of this
opinion, including (i) the corporate and organizational documents of the
Company, (ii) minutes and records of the corporate proceedings of the Company
with respect to the issuance of the Exchange Notes, (iii) the Registration
Statement and exhibits thereto and (iv) the Registration Rights Agreements, each
date February 4, 1998, among the Company and the respective Initial Purchasers
of the Old Notes as set forth therein.

     For purposes of this opinion, we have assumed the authenticity of all
documents submitted to us as originals, the conformity to the originals of all
documents submitted to us as copies and the authenticity of the originals of all
documents submitted to us as copies. We have also assumed the genuineness of the
signatures of persons signing all documents in connection with which this
opinion is rendered, the authority of such persons signing on behalf of the
parties thereto other than the Company and the due authorization, execution and
delivery of all documents by the parties thereto other than the Company. As to
any facts material to the opinions expressed herein which we have not
independently established or verified, we have relied upon statements and
representations of officers and other representatives of the Company and others.

     Based upon and subject to the foregoing qualifications, assumptions and 
limitations and the further limitations set forth below, we are of the opinion 
that:

     (1)  The Company is a corporation existing and in good standing under the 
          General Corporation Law of the State of Delaware.

     (2)  The sale and issuance of the Exchange Notes has been validly 
          authorized by the Company.

     (3)  When, as and if (i) the Registration Statement shall have become
          effective pursuant to the provisions of the Securities Act, (ii) the
          Indentures shall have been qualified pursuant to the provisions of the
          Trust Indenture Act of 1939, as amended, (iii) the Old Notes shall
          have been validly tendered to the Company, (iv) the Exchange Notes
          shall have been issued in the form and containing the terms described
          in the Registration Statement, the Indentures, the resolutions of the
          Company's Board of Directors (or authorized committee thereof)
          authorizing the foregoing and any legally required consents,
          approvals, authorizations and other order of the Commission and any
          other regulatory authorities to be obtained, and (v) the Exchange
          Notes have been authenticated by the respective Trustee, the Exchange
          Notes when issued pursuant to the Exchange Offer will be legally
          issued, fully paid and nonassessable and will constitute valid and
          binding obligations of the Company.

     Our opinions expressed above are subject to the qualifications that we
express no opinion as to the applicability of, compliance with, or effect of (i)
any bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent
conveyance, moratorium or other similar law affecting the enforcement of
creditors' rights generally, (ii) general principles of equity (regardless of
whether

enforcement is considered in a proceeding in equity or at law), (iii) public
policy considerations which may limit the rights of parties to obtain certain
remedies and (iv) any laws except the laws of the State of New York and the
General Corporation Law of the State of Delaware. We advise you that issues
addressed by this letter may be governed in whole or in part by other laws, but
we express no opinion as to whether any relevant difference exists between the
laws upon which our opinions are based and any other laws which may actually
govern. For purposes of the opinion in paragraph 1, we have relied exclusively
upon certificates issued by the Delaware Secretary of State and such opinions
are not intended to provide any conclusion or assurance beyond that conveyed by
such certificates. We have assumed without investigation that there has been no
relevant change or development between the respective dates of such certificates
and the date of this letter.

     We hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement. We also consent to the reference to our firm under the
heading "Legal Matters" in the Registration Statement. In giving this consent,
we do not thereby admit that we are in the category of persons whose consent is
required under Section 7 of the Securities Act of the rules and regulations of
the Commission.

     We do not find it necessary for the purposes of this opinion, and
accordingly we do not purport to cover herein, the application of the securities
or "Blue Sky" laws of the various states to the issuance of the Exchange Notes.

     This opinion is limited to the specific issues addressed herein, and no
opinion may be inferred or implied beyond that expressly stated herein. We
assume no obligation to revise or supplement this opinion should the present
laws of the State of New York or the General Corporation Law of the State of
Delaware be changed by legislative action, judicial decision or otherwise.

     This opinion is furnished to you in connection with the filing of the
Registration Statement, and is not to be used, circulated, quoted or otherwise
relied upon for any other purposes.

                                        Yours very truly,

                                        /s/ KIRKLAND & ELLIS

  The undersigned hereby acknowledges receipt of the Prospectus, dated March
5, 1998 (as it may be supplemented and amended from time to time, the
"Prospectus") of Navistar International Corporation, a Delaware corporation
(the "Company"), and this Letter of Transmittal (the "Letter of Transmittal"),
that together constitute the Company's offer to exchange (the "Exchange
Offer"): (i) $1,000 principal amount of its Series B 7% Senior Notes due 2003
(the "Senior Exchange Notes"), which will have been registered under the
Securities Act of 1933, as amended (the "Securities Act"), for each $1,000
principal amount of its outstanding 7% Senior Notes due 2003 (the "Old Senior

Subordinated Notes due 2008 (the "Senior Subordinated Exchange Notes" and,
together with the Senior Exchange Notes, the "Exchange Notes"), which will

amount of its outstanding 8% Senior Subordinated Notes due 2008 (the "Old

ascribed to them in the Prospectus.
 
  The undersigned hereby tenders the Old Notes described in Box 1 below (the
"Tendered Notes") pursuant to the terms and conditions described in the
Prospectus and this Letter of Transmittal. The undersigned is the registered
owner of all the Tendered Notes and the undersigned represents that it has

  Subject to, and effective upon, the acceptance for exchange of the Tendered
Notes, the undersigned hereby exchanges, assigns and transfers to, or upon the
order of, the Company all right, title, and interest in, to and under the
Tendered Notes.
 
  Please issue the Exchange Notes exchanged for Tendered Notes in the name(s)
of the undersigned. Similarly, unless otherwise indicated under "SPECIAL

certificates for the Exchange Notes (and accompanying documents, as
appropriate) to the undersigned at the address shown below in Box 1.
 
  The undersigned hereby irrevocably constitutes and appoints the Exchange
Agent as the true and lawful agent and attorney in fact of the undersigned
with respect to the Tendered Notes, with full power of substitution (such
power of attorney being deemed to be an irrevocable power coupled with an
interest), to (i) deliver the Tendered Notes to the Company or cause ownership
of the Tendered Notes to be transferred to, or upon the order of, the Company,
on the books of the registrar for the Old Notes and deliver all accompanying
evidences of transfer and authenticity to, or upon the order of, the Company
upon receipt by the Exchange Agent, as the undersigned's agent, of the
Exchange Notes to which the undersigned is entitled upon acceptance by the
Company of the Tendered Notes pursuant to the Exchange Offer, and (ii) receive
all benefits and otherwise exercise all rights of beneficial ownership of the
Tendered Notes, all in accordance with the terms of the Exchange Offer.
 
  The undersigned understands that tenders of the Old Notes pursuant to the
procedures described under the caption "The Exchange Offer" in the Prospectus
and in the instructions hereto will constitute a binding agreement between the
undersigned and the Company upon the terms and subject to the conditions of
the Exchange Offer, subject only to withdrawal of such tenders on the terms
set forth in the Prospectus under the caption "The Exchange Offer--Withdrawal
of Tenders." All authority herein conferred or agreed to be conferred shall
survive the death or incapacity of the undersigned and any Beneficial
Owner(s), and every obligation of the undersigned or any Beneficial Owner(s)
hereunder shall be binding upon the heirs, representatives, successors, and
assigns of the undersigned and such Beneficial Owner(s).
 
  The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, exchange, assign, and transfer the Tendered
Notes and that the Company will acquire good and unencumbered title thereto,
free and clear of all liens, restrictions, charges, encumbrances, and adverse
claims when the Tendered Notes are acquired by the Company as contemplated
herein. The undersigned and each Beneficial Owner will, upon request, execute
and deliver any additional documents reasonably requested by the Company or
the Exchange Agent as necessary or desirable to complete and give effect to
the transactions contemplated hereby.
 
  The undersigned hereby represents and warrants that the information set
forth in Box 2 is true and correct.
 
  By accepting the Exchange Offer, the undersigned hereby represents and
warrants that (i) the Exchange Notes to be acquired by the undersigned and any
Beneficial Owner(s) in connection with the Exchange Offer are being acquired
by the undersigned and any Beneficial Owner(s) in the ordinary course of
business of the undersigned and any Beneficial Owner(s), (ii) the undersigned
and each Beneficial Owner are not participating, do not intend to participate,
and have no arrangement or understanding with any person to participate, in
the distribution of the Exchange Notes, (iii) except as otherwise disclosed in
writing herewith, neither the undersigned nor any Beneficial Owner is an
"affiliate," as defined in Rule 405 under the Securities Act, of the Company,
and (iv) the undersigned and each Beneficial Owner acknowledge and agree that
any person participating in the Exchange Offer with the intention or for the
purpose of distributing the Exchange Notes must comply with the registration
and prospectus delivery requirements of the Securities Act, in connection with
a secondary resale of the Exchange Notes acquired by such person and cannot
rely on the position of the Staff of the Securities and Exchange Commission
(the "Commission") set forth in the no-action letters that are discussed in
the section of the Prospectus entitled "The Exchange Offer." In addition, by
accepting the Exchange Offer, the undersigned hereby (i) represents and
warrants that, if the undersigned or any Beneficial Owner of the Old

acquired the Old Notes for its own account as a result of market-making
activities or other trading activities and has not entered into any
arrangement or understanding with the Company or any "affiliate" of the
Company (within the meaning of Rule 405 under the Securities Act) to
distribute the Exchange Notes to be received in the Exchange Offer, and (ii)
acknowledges that, by receiving Exchange Notes for its own account in exchange
for the Old Notes, where such Old Notes were acquired as a result of market-
making activities or other trading activities, such Participating Broker-
Dealer will deliver a prospectus meeting the requirements of the Securities
Act in connection with any resale of such Exchange Notes.
 
  Holders of the Old Notes that are tendering by book-entry transfer to the
Exchange Agent's account at DTC can execute the tender through the DTC
Automated Tender Offer Program ("ATOP"), for which the transaction will be
eligible. DTC participants that are accepting the Exchange Offer must transmit
their acceptance to DTC, which will verify the acceptance and execute a book-
entry delivery to the Exchange Agent's DTC account. DTC will then send an
Agent's Message to the Exchange Agent for its acceptance. DTC participants may
also accept the Exchange Offer prior to the Expiration Date by submitting a
Notice of Guaranteed Delivery or Agent's Message relating thereto as described
herein under Instruction 2, "Guaranteed Delivery Procedures."

                     INSTRUCTIONS TO LETTER OF TRANSMITTAL
 
                   FORMING PART OF THE TERMS AND CONDITIONS
                             OF THE EXCHANGE OFFER
 
  1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND THE OLD NOTES. This Letter of
Transmittal is to be completed by registered Holders of the Old Notes if
certificates representing such Old Notes are to be forwarded herewith pursuant
to the procedures set forth in the Prospectus under "The Exchange Offer--
Procedures for Tendering," unless delivery of such certificates is to be made
by book-entry transfer to the Exchange Agent's account maintained by DTC
through ATOP. For a holder to properly tender the Old Notes pursuant to the
Exchange Offer, a properly completed and duly executed copy of this Letter of
Transmittal, including Substitute Form W-9, and any other documents required
by this Letter of Transmittal must be received by the Exchange Agent at its
address set forth herein, and either (i) certificates for Tendered Notes must
be received by the Exchange Agent at its address set forth herein, or (ii)
such Tendered Notes must be transferred pursuant to the procedures for book-
entry transfer described in the Prospectus under the caption "The Exchange
Offer--Procedures for Tendering" (and a confirmation of such transfer received
by the Exchange Agent), in each case prior to 5:00 p.m., New York City time,
on the Expiration Date. The method of delivery of certificates for Tendered
Notes, this Letter of Transmittal and all other required documents to the
Exchange Agent is at the election and risk of the tendering holder and the
delivery will be deemed made only when actually received by the Exchange
Agent. If delivery is by mail, registered mail with return receipt requested,
properly insured, is recommended. Instead of delivery by mail, it is
recommended that the Holder use an overnight or hand delivery service. In all
cases, sufficient time should be allowed to assure timely delivery. No Letter
of Transmittal or Tendered Notes should be sent to the Company. Neither the
Company nor the Exchange Agent is under any obligation to notify any tendering
holder of the Company's acceptance of Tendered Notes prior to the closing of
the Exchange Offer.
 
  2. GUARANTEED DELIVERY PROCEDURES. If a registered Holder desires to tender
the Old Notes pursuant to the Exchange Offer and (a) certificates representing
such Tendered Notes are not immediately available, (b) time will not permit
such Holder's Letter of Transmittal, certificates representing such Tendered
Notes and all other required documents to reach the Exchange Agent on or prior
to the Expiration Date, or (c) the procedures for book-entry transfer cannot
be completed on or prior to the Expiration Date, such Holder may nevertheless
tender such Tendered Notes with the effect that such tender will be deemed to
have been received on or prior to the Expiration Date if the procedures set
forth below and in the Statement under "The Exchange Offer--Guaranteed
Delivery Procedures" (including the completion of Box 4 above) are followed.
Pursuant to such procedures, (i) the tender must be made by or through an
Eligible Institution (as defined), (ii) a properly completed and duly executed
Notice of Guaranteed Delivery, substantially in the form provided by the
Company herewith, or an Agent's Message with respect to a guaranteed delivery
that is accepted by the Company, must be received by the Exchange Agent on or
prior to the Expiration Date, and (iii) the certificates for the Tendered
Notes, in proper form for transfer (or a Book-Entry Confirmation of the
transfer of such Tendered Notes to the Exchange Agent's account at DTC as
described in the Prospectus), together with a Letter of Transmittal (or
manually signed facsimile thereof) properly completed and duly executed, with
any required signature guarantees and any other documents required by the
Letter of Transmittal or a properly transmitted Agent's Message, must be
received by the Exchange Agent within three New York Stock Exchange trading
days after the date of execution of the Notice of Guaranteed Delivery. Any
holder who wishes to tender the Old Notes pursuant to the guaranteed delivery
procedures described above must ensure that the Exchange Agent receives the
Notice of Guaranteed Delivery relating to such Tendered Notes prior to 5:00
p.m., New York City time, on the Expiration Date. Failure to complete the
guaranteed delivery procedures outlined above will not, of itself, affect the
validity or effect a revocation of any Letter of Transmittal form properly
completed and executed by an Eligible Holder who attempted to use the
guaranteed delivery process.

  3. BENEFICIAL OWNER INSTRUCTIONS TO REGISTERED HOLDERS. Only a holder in
whose name Tendered Notes are registered on the books of the registrar (or the
legal representative or attorney-in-fact of such registered holder) may
execute and deliver this Letter of Transmittal. Any Beneficial Owner of
Tendered Notes who is not the registered holder must arrange promptly with the
registered holder to execute and deliver this Letter of Transmittal on his or
her behalf through the execution and delivery to the registered holder of the
"Instructions to Registered Holder and/or Book-Entry Transfer Facility
Participant from Beneficial Owner" form accompanying this Letter of
Transmittal.
 
  4. PARTIAL TENDERS. Tenders of the Old Notes will be accepted only in
integral multiples of $1,000 in principal amount. If less than the entire
principal amount of the Old Notes held by the holder is tendered, the
tendering holder should fill in the principal amount tendered in the column
labeled "Aggregate Principal Amount Tendered" of the box entitled "Description
of the Old Notes Tendered" (see Box 1) above. The entire principal amount of
the Old Notes delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated. If the entire principal amount of all the
Old Notes held by the holder is not tendered, then the Old Notes for the
principal amount of the Old Notes not tendered and Exchange Notes issued in
exchange for any Old Notes tendered and accepted will be sent to the Holder at
his or her registered address, unless a different address is provided in the
appropriate box on this Letter of Transmittal, as soon as practicable
following the Expiration Date.
 
  5. SIGNATURES ON THE LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS;
GUARANTEE OF SIGNATURES. If this Letter of Transmittal is signed by the
registered holder(s) of the Tendered Notes, the signature must correspond with
the name(s) as written on the face of the Tendered Notes without alteration,
enlargement or any change whatsoever.
 
  If any of the Tendered Notes are owned of record by two or more joint
owners, all such owners must sign this Letter of Transmittal. If any Tendered
Notes are held in different names, it will be necessary to complete, sign and
submit as many separate copies of the Letter of Transmittal as there are
different names in which Tendered Notes are held.
 
  If this Letter of Transmittal is signed by the registered holder(s) of
Tendered Notes, and Exchange Notes issued in exchange therefor are to be
issued (and any untendered principal amount of Old Notes is to be reissued) in
the name of the registered holder(s), then such registered holder(s) need not
and should not endorse any Tendered Notes, nor provide a separate bond power.
In any other case, such registered holder(s) must either properly endorse the
Tendered Notes or transmit a properly completed separate bond power with this
Letter of Transmittal, with the signature(s) on the endorsement or bond power
guaranteed by a Medallion Signature Guarantor (as defined below).
 
  If this Letter of Transmittal is signed by a person other than the
registered holder(s) of any Tendered Notes, such Tendered Notes must be
endorsed or accompanied by appropriate bond powers, in each case, signed as
the name(s) of the registered holder(s) appear(s) on the Tendered Notes, with
the signature(s) on the endorsement or bond power guaranteed by a Medallion
Signature Guarantor.
 
  If this Letter of Transmittal or any Tendered Notes or bond powers 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, evidence satisfactory to the Company of their authority to so act
must be submitted with this Letter of Transmittal.
 
  Signatures on this Letter of Transmittal must be guaranteed by a recognized
participant in the Securities Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Program or the Stock Exchange Medallion
Program (each a "Medallion Signature Guarantor"), unless the Tendered Notes
are tendered (i) by a registered Holder of Tendered Notes (or by a participant
in DTC whose name appears on a security position listing as the owner of such
Tendered Notes) who has not completed Box 3 ("Special Delivery
 
                                       9
<PAGE>
 
Instructions") on this Letter of Transmittal, or (ii) for the account of a
member firm of a registered national securities exchange, a member of the
National Association of Securities Dealers, Inc. ("NASD") or a commercial bank
or trust company having an office or correspondent in the United States (each
of the foregoing being referred to as an "Eligible Institution"). If the
Tendered Notes are registered in the name of a person other than the signor of
the Letter of Transmittal or if the Old Notes not tendered are to be returned
to a person other than the registered Holder, then the signature on this
Letter of Transmittal accompanying the Tendered Notes must be guaranteed by a
Medallion Signature Guarantor as described above. Beneficial owners whose Old
Notes are registered in the name of a broker, dealer, commercial bank, trust
company or other nominee must contact such broker, dealer, commercial bank,
trust company or other nominee if they desire to tender such Old Notes.
 
  6. SPECIAL DELIVERY INSTRUCTIONS. Tendering holders should indicate in Box 3
the name and address to which the Exchange Notes and/or substitute the Old
Notes for principal amounts not tendered or not accepted for exchange are to
be sent, if different from the name and address of the person signing this
Letter of Transmittal. In the case of issuance in a different name, the
taxpayer identification or social security number of the person named must
also be indicated.
 
  7. TRANSFER TAXES. The Company will pay all transfer taxes, if any,
applicable to the exchange of Tendered Notes pursuant to the Exchange Offer.
If, however, a transfer tax is imposed for any reason other than the transfer
and exchange of Tendered Notes pursuant to the Exchange Offer, then the amount
of any such transfer taxes (whether imposed on the registered holder or on any
other person) will be payable by the tendering holder. If satisfactory
evidence of payment of such taxes or exemption therefrom is not submitted with
this Letter of Transmittal, the amount of such transfer taxes will be billed
directly to such tendering holder.
 
  Except as provided in this Instruction 7, it will not be necessary for
transfer tax stamps to be affixed to the Tendered Notes listed in this Letter
of Transmittal.
 
  8. TAX IDENTIFICATION NUMBER. Federal income tax law requires that the
holder(s) of any Tendered Notes which are accepted for exchange must provide
the Exchange Agent (as payor) with its correct taxpayer identification number
("TIN"), which, in the case of a holder who is an individual, is his or her
social security number. If the Exchange Agent is not provided with the correct
TIN, the Holder may be subject to backup withholding and a $50 penalty imposed
by the Internal Revenue Service. (If withholding results in an over-payment of
taxes, a refund may be obtained.) Certain holders (including, among others,
all corporations and certain foreign individuals) are not subject to these
backup withholding and reporting requirements. See the enclosed "Guidelines
for Certification of Taxpayer Identification Number on Substitute Form W-9"
for additional instructions.
 
  To prevent backup withholding, each holder of Tendered Notes must provide
such holder's correct TIN by completing the Substitute Form W-9 set forth
herein, certifying that the TIN provided is correct (or that such holder is
awaiting a TIN), and that (i) the holder has not been notified by the Internal
Revenue Service that such holder is subject to backup withholding as a result
of failure to report all interest or dividends or (ii) if previously so
notified, the Internal Revenue Service has notified the holder that such
holder is no longer subject to backup withholding. If the Tendered Notes are
registered in more than one name or are not in the name of the actual owner,
consult the "Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9" for information on which TIN to report.
 
  The Company reserves the right in its sole discretion to take whatever steps
are necessary to comply with the Company's obligation regarding backup
withholding.
 
  9. VALIDITY OF TENDERS. All questions as to the validity, form, eligibility
(including time of receipt), acceptance and withdrawal of Tendered Notes will
be determined by the Company in its sole discretion, which determination will
be final and binding. The Company reserves the right to reject any and all Old
Notes not validly tendered or any Old Notes the Company's acceptance of which
would, in the opinion of the Company or its counsel, be unlawful. The Company
also reserves the right to waive any conditions of the Exchange Offer or
 
                                      10
<PAGE>
 
defects or irregularities in tenders of the Old Notes as to any ineligibility
of any holder who seeks to tender the Old Notes in the Exchange Offer. The
interpretation of the terms and conditions of the Exchange Offer (including
this Letter of Transmittal and the instructions hereto) by the Company shall
be final and binding on all parties. Unless waived, any defects or
irregularities in connection with tenders of the Old Notes must be cured
within such time as the Company shall determine. Neither the Company, the
Exchange Agent nor any other person shall be under any duty to give
notification of defects or irregularities with respect to tenders of the Old
Notes, nor shall any of them incur any liability for failure to give such
notification. Tenders of the Old Notes will not be deemed to have been made
until such defects or irregularities have been cured or waived. Any Old Notes
received by the Exchange Agent that are not properly tendered and as to which
the defects or irregularities have not been cured or waived will be returned
by the Exchange Agent to the tendering holders, unless otherwise provided in
this Letter of Transmittal, as soon as practicable following the Expiration
Date.
 
  10. WAIVER OF CONDITIONS. The Company reserves the absolute right to amend,
waive or modify any of the conditions in the Exchange Offer in the case of any
Tendered Notes.
 
  11. NO CONDITIONAL TENDER. No alternative, conditional, irregular, or
contingent tender of the Old Notes or transmittal of this Letter of
Transmittal will be accepted.
 
  12. MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES. Any tendering Holder
whose Old Notes have been mutilated, lost, stolen or destroyed should contact
the Exchange Agent at the address indicated herein for further instructions.
 
  13. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions and requests for
assistance and requests for additional copies of the Prospectus or this Letter
of Transmittal may be directed to the Exchange Agent at the address indicated
herein. Holders may also contact their broker, dealer, commercial bank, trust
company or other nominee for assistance concerning the Exchange Offer.
 
  14. ACCEPTANCE OF TENDERED NOTES AND ISSUANCE OF EXCHANGE NOTES; RETURN OF
THE OLD NOTES. Subject to the terms and conditions of the Exchange Offer, the
Company will accept for exchange all validly tendered Old Notes as soon as
practicable after the Expiration Date and will issue Exchange Notes therefor
as soon as practicable thereafter. For purposes of the Exchange Offer, the
Company shall be deemed to have accepted Tendered Notes when, as and if the
Company has given written or oral notice (immediately followed in writing)
thereof to the Exchange Agent. If any Tendered Notes are not exchanged
pursuant to the Exchange Offer for any reason, such unexchanged Old Notes will
be returned, without expense, to the undersigned at the address shown in Box 1
or at a different address as may be indicated herein under "Special Delivery
Instructions" (Box 3).
   
  15. WITHDRAWAL. Tenders may be withdrawn only pursuant to the procedures set
forth in the Prospectus under the caption "The Exchange Offer--Withdrawal of
Tenders."
