                             ---------------------
 
    Nortek, Inc., a Delaware corporation ("Nortek" or the "Company"), hereby
offers (the "Exchange Offer"), upon the terms and subject to the conditions set
forth in this Prospectus and the accompanying letter of transmittal (the "Letter
of Transmittal"), to exchange an aggregate principal amount of up to
$175,000,000 of its 9 1/4% Series B Senior Notes due 2007 (the "Exchange Notes")
of the Company for a like principal amount of the issued and outstanding 9 1/4%
Series A Senior Notes due 2007 (the "Original Notes" and together with the
Exchange Notes, the "Notes") from the holders (the "Holders") thereof. The form
and terms of the Exchange Notes are identical in all material respects to the
form and terms of the Original Notes except that the Exchange Notes will not
contain terms with respect to transfer restrictions (other than those that might
be imposed by state securities laws) or, except in limited circumstances,
provide for the payment of Liquidated Damages (as defined).
 
    The Original Notes are and the Exchange Notes will be senior unsecured
obligations of the Company and will rank pari passu in right of payment with all
existing and future senior unsecured indebtedness of the Company and senior in
right of payment to all existing and future subordinated indebtedness of the
Company. The Exchange Notes will be effectively subordinated to all existing and
future secured indebtedness of the Company, to the extent of the value of the
assets securing such indebtedness, and to all existing and future indebtedness
and other obligations of the Company's subsidiaries. At December 31, 1996, after
giving effect to the issuance and sale of the Original Notes (the "Offering")
and the application of the net proceeds therefrom, the Exchange Notes would have
been effectively subordinated to approximately $172.6 million of indebtedness
for borrowed money, trade payables and accrued liabilities of the Company's
subsidiaries. See "Description of Notes -- General." Subject to certain
restrictions, the Indenture pursuant to which the Original Notes were issued and
the Exchange Notes will be issued, permits the Company and its subsidiaries to
incur additional indebtedness, including indebtedness which may be secured.
 
    Interest on the Exchange Notes will be payable semi-annually on March 15 and
September 15 of each year, commencing September 15, 1997. The Exchange Notes
will mature on March 15, 2007. The Exchange Notes will be redeemable at the
option of the Company, in whole or in part, at any time and from time to time on
or after March 15, 2002 at the redemption prices set forth herein, together with
accrued and unpaid interest, if any, to the date of redemption. Upon a Change of
Control (as defined), holders of the Exchange Notes will have the right, subject
to certain exceptions, restrictions and conditions, to require the Company to
purchase all or any of their Notes at 101% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the date of purchase. See "Description
of Notes."
 
    The Exchange Notes are being offered hereunder in order to satisfy certain
obligations of the Company contained in the Registration Rights Agreement, dated
March 17, 1997, among the Company and the other signataries thereto (the
"Registration Rights Agreement"). The Company believes that based on
interpretations by the staff of the Securities and Exchange Commission (the
"Commission"), Exchange Notes issued pursuant to the Exchange Offer in exchange
for Original Notes may be offered for resale, resold and otherwise transferred
by each Holder thereof (other than (i) a broker-dealer who purchased Original
Notes directly from the Company or any of its "affiliates" within the meaning of
Rule 405 under the Securities Act of 1933, as amended (the "Securities Act") for
resale pursuant to Rule 144A or any other available exemption under the
Securities Act or (ii) a person that is such an "affiliate" of the Company)
without compliance with the registration and prospectus delivery provisions of
the Securities Act, provided that such Exchange Notes are acquired in the
ordinary course of such Holder's business and such Holder is not participating,
and has no arrangement with any such person to participate, in the distribution
of the Exchange Notes.
 
    Each broker-dealer participating in the Exchange Offer (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 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 Original Notes where such
Original Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities. The Company has agreed that, for a
period of 180 days after the Expiration Date (as defined), it will make this
Prospectus and any amendment or supplement to this Prospectus available to any
Participating Broker-Dealer for use in connection with any such resale. See
"Plan of Distribution."
 
    The Company will not receive any proceeds from the Exchange Offer and will
pay the expenses incident to the Exchange Offer. Tenders of Original Notes may
be withdrawn at any time prior to the Expiration Date. In the event the Company
terminates the Exchange Offer and does not accept for exchange any Original
Notes, the Company will promptly return the Original Notes to the Holders
thereof. See "The Exchange Offer."

SEE "RISK FACTORS" BEGINNING ON PAGE 12 FOR A DISCUSSION OF CERTAIN FACTORS THAT
 SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS IN EVALUATING THE EXCHANGE OFFER
                        AND AN INVESTMENT IN THE NOTES.
                             ---------------------
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.
                             ---------------------
               THE DATE OF THIS PROSPECTUS IS             , 1997.

     The Exchange Offer is not being made to, nor will the Company accept
surrenders for Exchange Notes from, Holders of Original Notes in any
jurisdiction in which the Exchange Offer or the acceptance thereof would not be
in compliance with the Securities or Blue Sky Laws for such jurisdiction.
 
     The Exchange Notes will be available initially only in book-entry form. The
Company expects that the Exchange Notes issued pursuant to this Exchange Offer
will be issued in the form of one or more Global Notes (as defined), which will
be deposited with, or on behalf of, The Depository Trust Company (the
"Depositary") 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 Depositary and its participants. After the initial issuance of
the Global Note, Exchange Notes in certificated form will be issued in exchange
for the Global Note only on the terms set forth in the Indenture (as defined).
See "Description of Notes -- Book-Entry; Delivery and Form."
 
     Prior to the Exchange Offer, there has been no public market for the
Original Notes or Exchange Notes. To the extent that Original Notes are tendered
and accepted in the Exchange Offer, a Holder's ability to sell untendered
Original Notes could be adversely affected. If a market for the Exchange Notes
should develop, the Exchange Notes could trade at a premium or discount from
their principal amount. The Company does not currently intend to list the
Exchange Notes on any securities exchange or to seek approval for quotation
through any automated quotation system.
 
     The Company has been advised by Bear, Stearns & Co., Inc., Wasserstein
Perrella Securities Inc. and BT Securities Corporation, the initial purchasers
(the "Initial Purchasers") of the Original Notes, that, following completion of
the Exchange Offer, they intend to make a market in the Exchange Notes; however,
such entities are under no obligation to do so and any market activities with
respect to the Exchange Notes may be discontinued at any time.
 
     Pursuant to the Indenture (as defined), so long as any of the Notes are
outstanding, whether or not the Company is subject to the reporting requirements
of Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), the Company will furnish to all holders of the Notes (i)
all quarterly and annual financial information that would be required to be
contained in a filing with the Commission on Forms 10-Q and 10-K if the Company
were required to file such Forms, including a "Management's Discussion and
Analysis of Financial Condition and Results of Operation" that describes the
financial condition and results of operations of the Company and its
subsidiaries and, with respect to annual information only, a report thereon by
the Company's independent certified public accountants and (ii) all reports that
would be required to be filed with the Commission on Form 8-K if the Company
were required to file such reports. The Company will also file a copy of all
such information with the Commission for public availability (unless the
Commission will not accept such filing) and make such information available to
investors or prospective investors of the Notes who request it in writing.

Original Notes. The Exchange Notes will be obligations of the Company entitled
to the benefits of the Indenture relating to the Notes. The form and terms of

Resale of the Exchange
Notes......................  Based on an interpretation by the staff of the
                             Commission set forth in no-action letters issued to
                             third parties, the Company believes that Exchange
                             Notes issued pursuant to the Exchange Offer in
                             exchange for Original Notes may be offered for
                             resale, resold and otherwise transferred by any
                             holder thereof (other than (i) a broker-dealer who
                             purchased such Original Notes directly from the
                             Company or any of its "affiliates" within the
                             meaning of Rule 405 under the Securities Act for
                             resale pursuant to Rule 144A or any other available
                             exemption under the Securities Act or (ii) a person
                             that is such an "affiliate" of the Company) without
                             compliance with the registration and prospectus
                             delivery provisions of the Securities Act, provided
                             that the holder is acquiring the Exchange Notes in
                             its ordinary course of business and is not
                             participating, and has no arrangement or
                             understanding with any person to participate, in
                             the distribution of the Exchange Notes. Holders of
                             Original Notes wishing to accept an Exchange Offer
                             must represent to the Company that such conditions
                             have been met. In the event that the Company's
                             belief is inaccurate, holders of Exchange Notes who
                             transfer Exchange Notes in violation of the
                             prospectus delivery provisions of the

                             registration thereunder may incur liability under
                             the Securities Act. The Company does not assume or
                             indemnify holders against such liability.
 
                             A Participating Broker-Dealer that receives

                             activities or other trading activities, must

                             Although such Participating Broker-Dealer may be an
                             "underwriter" within the meaning of the Securities
                             Act, the Letter of Transmittal states that by so
                             acknowledging and by delivering a prospectus, such
                             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 Original Notes. The
                             Company has agreed that, for a period of 180 days
                             after the Expiration Date, it will make this
                             Prospectus and any amendment or supplement to this
                             Prospectus available to any Participating
                             Broker-Dealer for use in connection with any such
                             resales. See "Plan of Distribution."

                             would not be in compliance with the securities or

                             initially at 104.625% of principal amount and
                             thereafter at prices declining to 100% from and
                             after March 15, 2005, plus accrued and unpaid
                             interest, if any, to the date of redemption. See

Change of Control..........  Upon a Change of Control (as defined), holders of

                             certain restrictions and conditions, to require the
                             Company to purchase all or any part of their
                             Exchange Notes

                             at 101% of the principal amount thereof, plus
                             accrued and unpaid interest, if any (the "Change of
                             Control Payment"), to the date of purchase. If a
                             Change of Control were to occur, there can be no
                             assurance that the Company would have sufficient
                             funds to make the Change of Control Payment with
                             respect to all Notes tendered by holders thereof.
                             In addition, the Company's ability to make such
                             payment may be limited by the terms of borrowing
                             and other agreements applicable to the Company or
                             its subsidiaries. See "Description of
                             Notes -- Change of Control" and "Description of
                             Other Obligations."
 
Ranking....................  The Exchange Notes will be senior unsecured
                             obligations of the Company and will rank pari passu
                             in right of payment with all existing and future
                             senior unsecured indebtedness of the Company and
                             senior in right of payment to all existing and
                             future subordinated indebtedness of the Company.
                             The Exchange Notes will be effectively subordinated
                             to all existing and future secured indebtedness of
                             the Company, to the extent of the value of the
                             assets securing such indebtedness, and to all
                             existing and future indebtedness and other
                             obligations of the Company's subsidiaries. Subject
                             to certain restrictions, the indenture pursuant to
                             which the Exchange Notes will be issued (the
                             "Indenture") permits the Company and its
                             subsidiaries to incur additional indebtedness,
                             including senior indebtedness which may be secured,
                             and other liabilities. At December 31, 1996, after
                             giving effect to the issuance and sale of the
                             Original Notes and the application of the net
                             proceeds therefrom, the Exchange Notes would have
                             been effectively subordinated to approximately
                             $172.6 million of indebtedness for borrowed money,
                             trade payables and accrued liabilities of the
                             Company's subsidiaries. See "Description of
                             Notes -- General."
 
Certain Covenants..........  The Indenture contains certain covenants that limit
                             the ability of the Company and its Restricted
                             Subsidiaries (as defined) to, among other things,
                             pay dividends, repurchase capital stock or make
                             certain other Restricted Payments (as defined),
                             incur additional Indebtedness (as defined), issue
                             preferred stock of Restricted Subsidiaries, make
                             certain Investments (as defined) and consummate
                             certain mergers, consolidations or sales of assets.
                             Upon certain Asset Sales (as defined), the Company
                             will be required in certain circumstances to offer
                             to apply certain proceeds thereof to purchase the
                             Notes. See "Description of Notes -- Certain
                             Covenants."

(1) Acquisitions have been accounted for under the purchase accounting method
    and dispositions have been accounted for as described in Note 2 of Notes to
    Consolidated Financial Statements contained in the Form 10-K incorporated
    herein by reference and in note (2) below.
 
(2) On January 2, 1992, the Company's subsidiary, Dixieline Products, Inc.
    ("Dixieline"), sold the assets of L.J. Smith, Inc. and recognized a pre-tax
    gain on the sale of approximately $8.0 million. On October 2, 1992, the
    Company sold its wholly-owned subsidiary Bend Millwork Systems, Inc.
    ("Bend") and recognized a pre-tax loss in 1992 of $22.5 million. In the
    third quarter of 1993, the Company provided a
 
                                       10
<PAGE>   12
 
    pre-tax valuation reserve of approximately $20.3 million to reduce the
    Company's net investment in Dixieline to estimated net realizable value. On
    March 31, 1994, the Company sold all the capital stock of Dixieline for
    approximately $18.8 million in cash and $6.0 million in preferred stock of
    the purchaser. No additional loss in 1994 was incurred in connection with
    this sale. In January 1995, the Company paid approximately $1.8 million as a
    final purchase price adjustment related to the sale of Bend and recorded a
    charge to pre-tax earnings in the fourth quarter of 1994.
 
(3) For purposes of calculating this ratio, "earnings" consist of earnings from
    continuing operations before provision for income taxes and fixed charges.
    "Fixed charges" consist of interest expense and the estimated interest
    portion of rental payments on operating leases. Such earnings were
    insufficient to cover fixed charges by $18.0 million and $11.6 million for
    the years ended December 31, 1992 and 1993, respectively.
 
(4) "EBITDA from operations" is the earnings (loss) from continuing operations
    before income taxes plus depreciation, amortization and interest expense,
    and excludes interest and dividend income, net gain on investment and
    marketable securities and loss on business sold. EBITDA from operations
    differs from Consolidated Cash Flow as defined in the Indenture. See
    "Description of Notes -- Certain Definitions." EBITDA from operations should
    not be considered as an alternative to net earnings as a measure of the
    Company's operating results or to cash flows as a measure of liquidity.
    EBITDA from operations principally differs from net increase (decrease) in
    unrestricted cash and cash equivalents shown on the Consolidated Statement
    of Cash Flows of the Company, prepared in accordance with generally accepted
    accounting principles, in that EBITDA from operations does not reflect
    capital expenditures, borrowings, principal and interest payments under debt
    and capital lease obligations, income tax payments and cash flows from other
    operating, investing and financing activities.
 
(5) Includes $5.7 million of restricted investments and marketable securities at
    December 31, 1996 (actual and as adjusted). See the Consolidated Financial
    Statements included in the Form 10-K incorporated herein by reference.
 
(6) The Adjusted Consolidated Statement of Operations Data and adjusted Other
    Consolidated Data for the year ended December 31, 1996 give effect to the
    Offering, the Refinancing and the Company Stock Purchases as if such
    transactions had occurred on January 1, 1996. The Consolidated Balance Sheet
    Data as adjusted give effect to the Offering, the Refinancing and the
    Company Stock Purchases as if such transactions had occurred on December 31,
    1996. A reconciliation from actual to as adjusted amounts is as follows
    (dollars in millions, except per share amounts):

                                  RISK FACTORS
 
     Prospective purchasers of the Exchange Notes should carefully review and
consider, among other things, the factors set forth below, as well as the other
information included or incorporated by reference in this Prospectus, before
making an investment in the Exchange Notes.
 
SUBSTANTIAL LEVERAGE
 
     The Company has a substantial amount of debt. At December 31, 1996, the
Company had approximately $280.5 million of consolidated debt. After giving
effect to the Offering, the Refinancing and the Company Stock Purchases as of
December 31, 1996, the Company would have had approximately $407.3 million of
consolidated debt. At December 31, 1996, the Company's debt to equity ratio was
2.4 to 1 and after giving effect to the Offering, the Refinancing and the
Company Stock Purchases as of December 31, 1996, the Company's debt to equity
ratio would have been 3.6 to 1. See "Capitalization" and "Description of Other
Obligations."
 
     The degree to which the Company is leveraged could have important
consequences to holders of the Exchange Notes, including the following: (i) the
Company's ability to obtain additional financing in the future for refinancing
indebtedness, acquisitions, working capital, capital expenditures or other
purposes may be impaired, (ii) funds available to the Company for its operations
and general corporate purposes or for capital expenditures will be reduced as a
result of the dedication of a substantial portion of the Company's consolidated
cash flow from operations to the payment of the principal and interest on its
indebtedness, (iii) the Company may be more highly leveraged than certain of its
competitors, which may place it at a competitive disadvantage, (iv) the
agreements governing the Company's and its subsidiaries' long-term indebtedness
(including indebtedness under the Company's 9 7/8% Senior Subordinated Notes due
2004 (the "9 7/8% Notes") and the Exchange Notes) and bank loans contain certain
restrictive financial and operating covenants, including, in the case of certain
indebtedness of subsidiaries, certain covenants that restrict the ability of the
Company's subsidiaries to pay dividends or make other distributions to the
Company (see "Description of Other Obligations"), (v) an event of default (not
cured or waived) under financial and operating covenants contained in the
Company's or its subsidiaries' debt instruments, including the Indenture, could
occur and have a material adverse effect on the Company, (vi) certain of the
borrowings under debt agreements of the Company's subsidiaries have floating
rates of interest, which causes the Company and its subsidiaries to be
vulnerable to increases in interest rates and (vii) the Company's substantial
degree of leverage could make it more vulnerable to a downturn in general
economic conditions.
 
     The terms of the Indenture allow for the incurrence of additional
Indebtedness (as defined). Except as set forth below, the incurrence of
additional Indebtedness is limited by certain conditions, including compliance
with a Consolidated Cash Flow Coverage Ratio (as defined) of 2 to 1, pro forma
for the additional Indebtedness. As of December 31, 1996, after giving effect to
the Offering and the Refinancing, the Company could have incurred approximately
$360.7 million of additional Indebtedness based on compliance with the
Consolidated Cash Flow Coverage Ratio. In addition, the Company and its
Restricted Subsidiaries (as defined) may incur specified levels of additional
Indebtedness without regard to compliance with the Consolidated Cash Flow
Coverage Ratio or any other financial ratio or covenant in the Indenture. The
Indenture places no restriction on the incurrence of Indebtedness by any of the
Company's Unrestricted Subsidiaries (as defined). See "Description of Notes." In
the event the Company or its subsidiaries were to incur additional Indebtedness,
whether for acquisitions, investment in its business or other general corporate
purposes, the Company's leverage could increase, which in turn could make it
more susceptible to the factors described above.
 
     The ability of the Company and its subsidiaries to make principal and
interest payments under long-term indebtedness (including the Notes) and bank
loans will be dependent upon their future performance, which is subject to
financial, economic and other factors affecting the Company and its
subsidiaries, some of which are beyond their control. There can be no assurance
that the current level of operating results of the Company and its subsidiaries
will continue or improve. The Company believes that it will need to access the
capital markets in the future in order to provide the funds necessary to repay a
significant portion of its indebtedness. There can be no assurance that any such
refinancing will be possible or that any additional financing can be obtained,
 
                                       12
<PAGE>   14
 
particularly in view of the Company's anticipated high levels of debt and the
debt incurrence restrictions under its existing debt agreements, including the
Indenture. If no such refinancing or additional financing were available, the
Company and/or its subsidiaries could default on their respective debt
obligations. In such case, virtually all other debt of the Company and its
subsidiaries, including payments to be made under the Notes, could become
immediately due and payable.
 
SECURED INDEBTEDNESS
 
     The Indenture will permit the Company to incur certain indebtedness secured
by a lien on assets of the Company (including indebtedness which may be incurred
under the Company Credit Facility (as defined)). The Exchange Notes are
unsecured and will be effectively subordinated to all existing and future
secured indebtedness of the Company to the extent of the value of the assets
securing such indebtedness. Accordingly, if an event of default occurs under any
agreement or instrument governing secured indebtedness of the Company, the
lenders thereunder will have a prior right to the assets of the Company securing
such indebtedness and may foreclose upon such collateral to the exclusion of the
holders of the Exchange Notes. In such event, such assets would first be used to
repay in full outstanding amounts under indebtedness secured thereby, resulting
in all or a portion of the Company's assets being unavailable to satisfy the
claims of the holders of Exchange Notes and holders of other unsecured
indebtedness. See "Description of Notes -- Certain Covenants."
 
STRUCTURAL SUBORDINATION
 
     The Exchange Notes will be obligations of the Company exclusively. Because
the operations of the Company are conducted entirely through subsidiaries, the
Company's cash flow and its ability to service debt, including the Exchange
Notes, are dependent upon the cash flow of its subsidiaries and the payment of
funds by those subsidiaries in the forms of loans, dividends or otherwise. The
subsidiaries, however, are legally distinct from the Company and have no
obligation, contingent or otherwise (except to the extent described below with
respect to the requirement to provide guaranties in certain circumstances), to
pay amounts due pursuant to the Exchange Notes or to make any funds available
for such payments.
 
     Certain agreements governing the Company's subsidiaries restrict the
ability of the subsidiaries to pay dividends or make other distributions to the
Company. See "Description of Other Obligations."
 
     In addition, while substantially all of the Company's subsidiaries are
currently wholly owned directly or indirectly by the Company, the ability of the
Company to cause any less than wholly owned subsidiary to pay dividends or make
other distributions to the Company may be limited by reason of contractual
restrictions or the need to consider the interests of the other owners of such
subsidiary. For example, a pro rata amount of any dividend distribution would in
most cases be required to be paid to the other owners of such subsidiary (and
thereby be subject to, and potentially prohibited by, the Limitations on
Restricted Payments covenant of the Indenture and similar covenants in other
agreements or instruments applicable to the Company, including without
limitation the indenture governing the 9 7/8% Notes). In addition, the terms of
any loan from any such less than wholly owned subsidiary to the Company may only
be able to be made, if at all, on terms less favorable to the Company than in
the case of a loan from a wholly owned subsidiary.
 
     Except to the extent that the Company may itself be a trade creditor with
recognized claims against its subsidiaries, claims of creditors of such
subsidiaries, including trade creditors, will have effective priority with
respect to the assets and earnings of such subsidiaries over the claims of
creditors of the Company, including holders of the Exchange Notes. At December
31, 1996, after giving effect to the Offering and the Refinancing, the Exchange
Notes would have been effectively subordinated to approximately $172.6 million
of indebtedness for borrowed money, trade payables and accrued liabilities of
the Company's subsidiaries. See "Description of Notes -- General."
 
     The Indenture provides that in the event any of the Company's subsidiaries
guarantees or otherwise becomes liable for the payment of any Indebtedness of
the Company (other than Indebtedness under the Company Credit Facility) such
subsidiary shall also guarantee the payment of the Exchange Notes. This
provision of the Indenture ceases to have effect in certain circumstances. In
the event any subsidiary provides
 
                                       13
<PAGE>   15
 
such a guaranty, the guaranty may, under certain circumstances, be subject to
avoidance or subordination under fraudulent conveyance laws or the preference
provisions of federal or state bankruptcy law. See "Description of Notes Certain
Covenants -- Limitation on Guaranties by Subsidiaries."
 
REPURCHASE OF NOTES UPON CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, the Company will be required to
make an offer to repurchase the Notes at a price equal to 101% of the principal
amount thereof, plus accrued and unpaid interest, if any, to the date of
repurchase. Certain events involving a Change of Control could result in
acceleration of, or similar repurchase obligations with respect to, indebtedness
outstanding under the Company Credit Facility, the 9 7/8% Notes or other
indebtedness of the Company or its subsidiaries that may be incurred in the
future. There can be no assurance that the Company will have sufficient
resources to repurchase the Notes, including the Exchange Notes, in the event it
becomes obligated to do so, particularly in the event of acceleration of, or the
need to comply with repurchase obligations with respect to, other indebtedness.
The failure to repurchase all of the tendered Notes in the event of a Change of
Control constitutes an event of default under the Indenture which may result in
the acceleration of the maturity of the Notes. The Change of Control repurchase
provisions may be deemed to have anti-takeover effects and may delay, defer or
prevent a merger, tender offer or other takeover attempt. See "Description of
Notes -- Change of Control", "-- Certain Covenants" and "-- Events of Default
and Remedies."
 
SENSITIVITY TO ECONOMIC CYCLES; AVAILABILITY AND PRICING OF RAW MATERIALS
 
     A significant percentage of the Company's sales of residential and
commercial building products is attributable to new residential and
nonresidential construction, which are affected by such cyclical factors as
interest rates, inflation, consumer spending habits and employment. This
exposure to cyclicality in the new construction market is partially mitigated by
the Company's increasing emphasis on the repair and replacement markets, which
are typically less cyclical. In addition, the Company is dependent upon raw
materials (including, among others, steel, copper, packaging material, plastics,
resins and aluminum) and components purchased from third parties. Accordingly,
the Company's results of operations and financial condition have in the past
been, and may again in the future be, adversely affected by increases in raw
material or component costs or their lack of availability.
 
COMPETITION
 
     Substantially all of the markets in which the Company participates are
highly competitive with respect to product quality, price, design innovations,
distribution, service, warranties, reliability, efficiency and financing terms.
Certain of the Company's competitors have greater financial and marketing
resources and brand awareness than the Company. Competitive factors could
require price reductions or increased spending on product development, marketing
and sales that would adversely affect the Company's operating results.
 
LACK OF PUBLIC MARKET
 
     There is no existing public market for the Original Notes or the Exchange
Notes and 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. The Initial
Purchasers have advised the Company that they currently intend to make a market
in the Notes but are not obligated to do so and may discontinue such market
making at any time without notice. In addition, such market making activity will
be subject to the limits imposed by the Securities Act and the 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
market will develop for any of the Exchange Notes or as to the liquidity of the
trading market for any of the Exchange Notes. If a trading market does not
develop or is not maintained, holders of the Exchange Notes may experience
difficulty in reselling such 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 trading market develops for the Exchange Notes,
future trading prices of such Exchange Notes will depend on many factors,
including, among other things, prevailing interest rates, the
 
                                       14
<PAGE>   16
 
Company's results of operations and the market for similar securities. Depending
on prevailing interest rates, the market for similar securities and other
factors, including the financial condition of the Company, the Exchange Notes
may trade at a discount from their principal amount.

                              DESCRIPTION OF NOTES
 
GENERAL
 
     The Original Notes were issued and the Exchange Notes will be issued
pursuant to an indenture (the "Indenture") dated as of March 17, 1997 between
the Company and State Street Bank and Trust Company, a Massachusetts banking
corporation, as trustee (the "Trustee"). The terms of the Exchange Notes include
those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), as
in effect on the date of the Indenture. The Notes are subject to all such terms,
and holders of the Notes are referred to the Indenture and the Trust Indenture
Act for a statement thereof. The following summary of certain provisions of the
Indenture, the Notes and the Registration Rights Agreement does not purport to
be complete and is qualified in its entirety by reference to the Indenture,
including the definitions included in the Indenture of certain terms used below.
Copies of the Indenture and the Registration Rights Agreement are exhibits to
the Registration Statement of which this Prospectus is a part and are publicly
available as set forth above under "-- Available Information." The definitions
of certain terms used in the following summary are set forth below under
"-- Certain Definitions."
 
     The form and terms of the Exchange Notes are the same as the form and terms
of the Original Notes (which they replace) except that (i) the Exchange Notes
bear a Series B designation, (ii) the Exchange Notes have been registered under
the Securities Act and, therefore, will not bear legends restricting the
transfer thereof (except as may be required under the state securities laws) and
(iii) the holders of Exchange Notes will generally not be entitled to certain
rights under the Registration Rights Agreement, including the provisions
providing for Liquidated Damages in certain circumstances relating to the timing
of the Exchange Offer, which rights will terminate when the Exchange Offer is
consummated. See "The Exchange Offer -- Registration Rights; Liquidated
Damages."
 
     The Notes will be unsecured senior obligations of the Company limited to
$175,000,000 aggregate principal amount. The Notes will rank senior in right of
payment to all existing and future subordinated Indebtedness of the Company,
including the 9 7/8% Notes, and pari passu in right of payment with all existing
and future senior unsecured Indebtedness of the Company. The Notes will be
effectively subordinated to all existing and future secured Indebtedness of the
Company, including secured Indebtedness pursuant to the Company Credit Facility,
to the extent of the value of the assets securing such Indebtedness, and the
Notes will be structurally subordinated to all Indebtedness and other
obligations (including trade payables) of the Company's Subsidiaries. At
December 31, 1996, after giving effect to the Offering and the Refinancing, the
Notes would have been effectively subordinated to approximately $172.6 million
of indebtedness for borrowed money, trade payables and accrued liabilities of
the Company's Subsidiaries.
 
     Although the Indenture contains certain covenants and provisions that
afford certain protections to holders of the Notes (the "Holders"), such
covenants and provisions would not necessarily afford the Holders of the Notes
protection in the event of a highly leveraged transaction involving the Company,
including a leveraged transaction initiated or supported by the Company, the
management of the Company or any affiliate of either party. See "-- Certain
Covenants" below.
 
PRINCIPAL, MATURITY AND INTEREST
 
     The Notes are limited in aggregate principal amount to $175,000,000 and
will mature on March 15, 2007. Interest on the Notes will accrue at the rate of
9 1/4% per annum and will be payable semi-annually on each March 15 and
September 15 commencing on September 15, 1997, to Holders on the immediately
preceding March 1 or September 1, whether or not a business day. Interest on the
Notes will accrue from the most recent date to which interest has been paid or,
if no interest has been paid, from the date of issuance of the Original Notes
and will continue to accrue after the occurrence of an event of default
described in clause (5) or (6) of the first paragraph under "-- Events of
Default and Remedies." Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months.
 
     Principal of, premium, if any, interest on, and Liquidated Damages, if any,
with respect to the Notes will be payable by wire transfer of immediately
available funds to the holder of the Global Notes; provided, that
 
                                       17
<PAGE>   19
 
payments of interest and Liquidated Damages, if any, may be made at the office
or agency of the Company maintained for such purpose or, at the option of the
Company, by check mailed to the Holders at their respective addresses set forth
in the register of Holders. Unless otherwise designated by the Company, the
Company's office or agency in New York will be the office of the Trustee
maintained for such purpose. The Notes will be issued only in registered form,
without coupons, in denominations of $1,000 and integral multiples thereof. The
Trustee is Paying Agent and Registrar under the Indenture. The Company may act
as Paying Agent or Registrar under the Indenture, and the Company may change the
Paying Agent or Registrar without notice to the Holders.
 
OPTIONAL REDEMPTION
 
     The Notes will be redeemable by the Company, in whole or in part, on or
after March 15, 2002 at the following redemption prices (expressed as a
percentage of the principal amount) if redeemed during the 12-month period
beginning March 15 of the years indicated below, in each case, together with
accrued and unpaid interest and Liquidated Damages, if any, to the redemption
date:
 
<TABLE>

          ---------------------------------------------------------------  ----------
          <S>                                                              <C>

          2004...........................................................    101.542%
          2005 and thereafter............................................    100.000%
</TABLE>
 
     Notice of the redemption must be mailed by first class mail at least 30 but
not more than 60 days before the redemption date to each Holder to be redeemed
at such Holder's registered address. If any Note is to be redeemed in part only,
the notice of redemption relating to that Note will state the principal amount
thereof to be redeemed and a new Note in principal amount equal to the
unredeemed portion will be issued in the name of the Holder upon cancellation of
the original Note. On and after the redemption date, interest ceases to accrue
on Notes or portions of Notes called for redemption, unless the Company shall
default in the payment of the redemption price. If less than all the outstanding
Notes are to be redeemed at any time, selection of the Notes for redemption will
be made by the Trustee by lot or, if such method is prohibited by the rules of
any stock exchange on which the Notes are then listed, any other method the
Trustee considers reasonable, provided that Notes shall be redeemed in principal
amounts of $1,000 or integral multiples thereof.
 
MANDATORY REDEMPTION
 
     The Company is not required to make mandatory redemption or sinking fund
payments with respect to the Notes. However, as described below, the Company may
be obligated, under certain circumstances, to make an offer to purchase (i) all
outstanding Notes at a redemption price of 101% of the principal amount thereof,
plus accrued and unpaid interest and Liquidated Damages, if any, to the date of
purchase, upon a Change of Control; and (ii) outstanding Notes with a portion of
the Excess Proceeds of Asset Sales at a redemption price of 100% of the
principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages, if any, to the date of purchase. See "-- Change of Control" and
"-- Certain Covenants -- Limitation on Use of Proceeds from Asset Sales."
 
CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, each Holder will have the right
to require the repurchase of all or any part of such Holder's Notes pursuant to
the offer described below (the "Change of Control Offer") at a purchase price
equal to 101% of the aggregate principal amount thereof plus accrued and unpaid
interest and Liquidated Damages, if any, to the date of purchase (the "Change of
Control Payment").
 
     Immediately following any Change of Control, the Company is required to
mail a notice to the Trustee and to each Holder stating: (i) that the Change of
Control Offer is being made pursuant to the Repurchase Upon Change of Control
covenant of the Indenture and that all Notes tendered will be accepted for
payment; (ii) the amount of the Change of Control Payment and the purchase date
(the "Change of Control Payment
 
                                       18

Date"), which may not be earlier than 30 days nor later than 60 days from the
date such notice is mailed; (iii) that any Note not tendered will continue to
accrue interest; (iv) that, unless the Company defaults in the payment thereof,
all Notes accepted for payment pursuant to the Change of Control Offer will
cease to accrue interest on and after the Change of Control Payment Date; (v)
that Holders electing to have any Notes purchased pursuant to a Change of
Control Offer will be required to surrender the Notes to be purchased to the
Paying Agent at the address specified in the notice prior to the close of
business on the third business day preceding the Change of Control Payment Date;
(vi) that Holders will be entitled to withdraw Notes they have tendered on the
terms and conditions set forth in such notice; and (vii) that Holders whose
Notes are being purchased only in part will be issued new Notes (or book-entry
notation made with respect thereto) equal in principal amount to the unpurchased
portion of the Notes tendered; provided that the portion of each Note purchased
and each such new Note issued (or book-entry notation, if applicable) shall be
in a principal amount of $1,000 or an integral multiple thereof.
 
     On the Change of Control Payment Date, the Company will, to the extent
lawful, (i) accept for payment all Notes or portions thereof tendered pursuant
to the Change of Control Offer and not withdrawn, (ii) deposit with the Paying
Agent an amount sufficient to pay the Change of Control Payment in respect of
all Notes or portions thereof so tendered and not withdrawn, and (iii) deliver
or cause to be delivered to the Trustee all Notes so tendered and not withdrawn
together with an Officers' Certificate specifying the Notes or portions thereof
tendered to the Company. The Paying Agent will promptly mail to each Holder of
Notes so tendered and not withdrawn the Change of Control Payment in respect of
such Notes, and the Trustee will promptly authenticate and mail to such Holder a
new Note (or cause to be transferred by book entry) equal in principal amount to
any unpurchased portion of the Notes surrendered; provided that each such new
Note shall be in a principal amount of $1,000 or an integral multiple thereof.
The Company will publicly announce the results of the Change of Control Offer on
or as soon as practicable after the Change of Control Payment Date.
 
     The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act, and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes triggered by a Change of Control.
 
     A "Change of Control" will be deemed to have occurred at such time as any
of the following events occur: (i) there is consummated any consolidation or
merger of the Company with or into another corporation, or all or substantially
all of the assets of the Company are sold, leased or otherwise transferred or
conveyed to another Person (other than pursuant to a bona fide pledge of assets
to secure Indebtedness made in accordance with the Indenture), and the holders
of the Company's common stock outstanding immediately prior to such
consolidation, merger, sale, lease or other transfer or conveyance or one or
more Exempt Persons do not hold, directly or indirectly, at least a majority of
the common stock of the continuing or surviving corporation immediately after
such consolidation or merger or at least a majority of the Equity Interests of
such Person; (ii) there is filed a report on Schedule 13D or 14D-1 (or any
successor schedule, form or report) pursuant to the Exchange Act disclosing that
any person (defined, solely for the purposes of the Change of Control provision,
as the term "person" is used in Section 13(d)(3) or Section 14(d)(2) of the
Exchange Act or any successor provision to either of the foregoing) has become
the beneficial owner (as the term "beneficial owner" is defined under Rule 13d-3
or any successor rule or regulation promulgated under the Exchange Act) of 50%
or more of the combined voting power of all the Company's then outstanding
securities entitled to vote generally for the election of directors; provided,
however, that a person shall not be deemed to be the beneficial owner of, or to
own beneficially, (A) any securities tendered pursuant to a tender or exchange
offer made by or on behalf of such person or any of such person's Affiliates or
associates until such tendered securities are accepted for purchase or exchange
thereunder, or (B) any securities if such beneficial ownership (1) arises solely
as a result of a revocable proxy delivered in response to a proxy or consent
solicitation made pursuant to the applicable rules and regulations under the
Exchange Act, and (2) is not also then reportable on Schedule 13D (or any
successor schedule) under the Exchange Act; or (iii) during any consecutive
two-year period, individuals who at the beginning of such period constituted the
Board of Directors of the Company (together with any new directors whose
election by such Board of Directors or whose nomination for election by the
stockholders of the Company was approved by a vote of 66 2/3% of the directors
then still in office who were either directors at the beginning of such period
or whose election or nomination for election was
 
                                       19
<PAGE>   21
 
previously so approved) cease for any reason to constitute a majority of the
Board of Directors of the Company then in office.
 
     Notwithstanding the foregoing, a Change of Control shall not be deemed to
have occurred under clause (ii) of the immediately preceding paragraph solely by
virtue of the Company, any Subsidiary of the Company, any employee stock
ownership plan or any other employee benefit plan of the Company or any such
Subsidiary, any other person holding securities of the Company for or pursuant
to the terms of any such employee benefit plan, or any Exempt Person, filing or
becoming obligated to file a report on Schedule 13D or Schedule 14D-1 (or any
successor schedule, form or report) under the Exchange Act disclosing beneficial
ownership by it of securities of the Company, whether in excess of 50% of the
combined voting power of the Company's then outstanding securities entitled to
vote generally for the election of directors or otherwise.
 
     The Change of Control purchase feature may in certain circumstances make
more difficult or discourage a takeover of the Company and, thus, the removal of
the incumbent management. Although the Company has from time to time received
and considered proposals which might involve a Change of Control, the Change of
Control purchase feature was not adopted as a result of management's knowledge
of any specific effort to accumulate shares of Common Stock or to obtain control
of the Company by means of a merger, tender offer, solicitation or otherwise, or
part of a plan by management to adopt a series of antitakeover provisions.
Instead, the Change of Control purchase feature is a standard term contained in
other similar debt offerings and the terms of such feature result from
negotiations between the Company and the Initial Purchasers.
 
     If a Change of Control were to occur, there can be no assurance that the
Company would have sufficient funds to make the Change of Control Payment in
respect of all Notes tendered by Holders thereof. In addition, the Company's
ability to make such payment may be limited by the terms of its then-existing
borrowings and other agreements applicable to the Company or its Subsidiaries.
Certain existing agreements applicable to certain of the Company's Subsidiaries
restrict the ability of these Subsidiaries to make distributions to the Company.
See "Description of Other Obligations."
 
     Neither the Board of Directors of the Company nor the Trustee may waive the
Change of Control repurchase feature of the Indenture.
 
     One of the events that constitutes a Change of Control under the Indenture
is a sale, lease or other transfer or conveyance of all or substantially all of
the assets of the Company. There is no precise established definition under
applicable law of the term "substantially all" and, accordingly, if the Company
were to engage in transactions in which it disposed of less than all of its
assets, a question could arise as to whether such disposition was of
"substantially all" of its assets and whether because of such disposition the
Company was required to repurchase the Notes as a result of a Change of Control.
 
CERTAIN COVENANTS
 
     Limitation on Restricted Payments.  The Company shall not, and shall not
permit any of its Restricted Subsidiaries to, directly or indirectly: (i)
declare or pay any dividend on, or make any distribution in respect of the
Company's or any such Restricted Subsidiary's Capital Stock or other Equity
Interests, except to the extent any such dividend or other distribution is (a)
actually received by the Company or a Restricted Subsidiary thereof or (b)
payable solely in shares of Capital Stock or other Equity Interests (other than
Redeemable Stock or Capital Stock convertible into any security other than such
Capital Stock) of the Company or such Restricted Subsidiary, as the case may be;
(ii) purchase, redeem or otherwise acquire or retire for value any Capital Stock
or other Equity Interests of the Company or any of its Restricted Subsidiaries
(other than Capital Stock or other Equity Interests held by the Company or any
Wholly-Owned Subsidiary of the Company that is a Restricted Subsidiary); (iii)
prepay, repay, purchase, repurchase, redeem, defease or otherwise acquire or
retire for value, prior to a scheduled repayment date, scheduled mandatory
sinking fund payment date or maturity date any Indebtedness of the Company that
is subordinate in right of payment to the Notes (other than in connection with
any refinancing of such Indebtedness permitted by the Indenture); or (iv) make
any Investment other than Permitted Investments (each such action described in
any of clauses (i) through (iv) above being referred to as a "Restricted
Payment"), if, at the time of such Restricted Payment, (1) a Default or Event of
Default shall have occurred and be continuing
 
                                       20
<PAGE>   22
 
or shall occur as a consequence thereof; (2) such Restricted Payment, together
with the aggregate amount of all other Restricted Payments declared or made on
or after the issue date of the Original Notes (including, without duplication,
Restricted Payments described in the next succeeding paragraph), exceeds the sum
of (A) 50% of the cumulative Consolidated Net Income of the Company for the
period commencing on January 1, 1997 through the last day of the fiscal quarter
immediately preceding the date of such proposed Restricted Payment (provided
that if the amount of such cumulative Consolidated Net Income divided by the
number of full fiscal quarters of the Company in the applicable period exceeds
$5,250,000, then such amount shall equal (i) 50% of the product of $5,250,000
multiplied by the number of full fiscal quarters in such period plus (ii) 75% of
the amount in excess of the product of $5,250,000 multiplied by the number of
full fiscal quarters in such period) (or, if the cumulative Consolidated Net
Income of the Company shall be a deficit, minus 100% of such deficit); (B) the
aggregate net cash proceeds, and the Fair Market Value of any property other
than cash, if any, received by the Company (other than from a Restricted
Subsidiary of the Company) from the issuance and sale of either Capital Stock of
the Company (other than Redeemable Stock or any Capital Stock convertible into
any security other than such Capital Stock) or Indebtedness that is convertible
into Capital Stock of the Company (other than Redeemable Stock or any Capital
Stock convertible into any security other than such Capital Stock), to the
extent such Indebtedness is actually converted into such Capital Stock; (C) an
amount equal to any cash and the Fair Market Value (at the time of receipt) of
other assets received by the Company or any of its Restricted Subsidiaries after
the date of the issuance of the Original Notes as a dividend or other
distribution from any Unrestricted Subsidiary; (D) the Fair Market Value of any
Investment held by either the Company or any Restricted Subsidiary of the
Company in any Unrestricted Subsidiary at the time such Unrestricted Subsidiary
is redesignated as a Restricted Subsidiary in accordance with the provisions of
the Indenture; and (E) $35,000,000; or (3) the Company could not incur at least
$1.00 of additional Indebtedness pursuant to the first paragraph of the
Limitation on Additional Indebtedness covenant.
 
     The foregoing provisions shall not prohibit, so long as no Default or Event
of Default shall have occurred and be continuing or shall occur as a consequence
thereof, (i) the payment of any dividend within 60 days after the date of
declaration thereof, if at such date of declaration such payment would have
complied with the provisions of the Indenture; (ii) the declaration and payment
by a Restricted Subsidiary of the Company which is required to file periodic
reports under Section 13 or 15(d) of the Exchange Act (a "Reporting Subsidiary")
of dividends on its common stock to all holders of such common stock on a pro
rata basis out of funds legally available for the payment of dividends, provided
that the amount of such dividends in any fiscal year of such Reporting
Subsidiary shall not exceed 25% of the Consolidated Net Income of such Reporting
Subsidiary for the immediately preceding fiscal year; (iii) the purchase,
redemption, acquisition, cancellation or other retirement for value of shares of
Capital Stock of the Company, options to purchase such shares or related stock
appreciation rights or similar securities held by current or former officers,
employees or directors (or their estates or beneficiaries under their estates)
of the Company or any Restricted Subsidiary; provided that the aggregate
consideration paid for such purchase, redemption, cancellation or other
retirement after the date hereof does not exceed $2,500,000 in the aggregate in
any fiscal year of the Company; (iv) the prepayment, repayment, purchase,
repurchase, redemption, defeasance or other acquisition or retirement for value
of any or all of the 9 7/8% Notes at any time within one year of the scheduled
maturity date thereof; and (v) the redemption, repurchase, defeasance or other
acquisition or retirement for value of Indebtedness of the Company that is
subordinated in right of payment to the Notes in exchange for, or out of the
proceeds of a substantially concurrent offering of, shares of Capital Stock of
the Company.
 
     Limitation on Additional Indebtedness.  The Company shall not, and shall
not permit any of its Restricted Subsidiaries to, directly or indirectly,
create, incur, issue, assume, guarantee or otherwise become directly or
indirectly liable with respect to (each, an "incurrence") any Indebtedness,
including, without limitation, Acquired Indebtedness; provided, however, that
the Company may incur Indebtedness if (i) no Default or Event of Default shall
have occurred and be continuing at the time or after giving effect to the
incurrence of such Indebtedness and (ii) the Consolidated Cash Flow Coverage
Ratio of the Company for the four full fiscal quarters ending immediately prior
to the date of the incurrence of such additional Indebtedness is at least 2.0 to
1.0.

     all other Indebtedness incurred pursuant to this clause (iii) and
     outstanding on such date, shall not exceed the greater of (a) $75,000,000
     and (b) the sum of 85% of Eligible Receivables of the Company and its
     Subsidiaries, plus 65% of Eligible Inventory of the Company and its
     Subsidiaries;
 
          (iv) Indebtedness of (a) Broan Limited and any Canadian Subsidiaries
     which are Restricted Subsidiaries under the Broan Limited Credit Facility;
     provided that (1) the aggregate outstanding principal amount (including the
     available undrawn amount of any letters of credit issued thereunder) so
     incurred on any date, together with all other Indebtedness incurred
     pursuant to this clause (iv) and outstanding on such date, shall not exceed
     the greater of (x) $30,000,000 (Canadian) and (y) the sum of 85% of
     Eligible Receivables of Broan Limited and the Canadian Subsidiaries which
     are Restricted Subsidiaries plus 65% of Eligible Inventory of Broan Limited

     shall be secured only by Liens on assets of Broan Limited and the Canadian
     Subsidiaries which are Restricted Subsidiaries, and (b) the Company under
     its limited guaranty of not more than $20,000,000 (Canadian) of the
     Indebtedness of Broan Limited and the Canadian Subsidiaries which are
     Restricted Subsidiaries under the Broan Limited Credit Facility;
 
          (v) Indebtedness of Universal-Rundle Corporation for facility
     expansion or improvement or joint venture investment purposes not exceeding
     at any time $6,000,000 in aggregate outstanding principal amount and, if
     secured, secured only by Liens on assets of Universal-Rundle Corporation or
     the applicable joint venture;
 
          (vi) Indebtedness of the Company to any of its Wholly-Owned
     Subsidiaries that is a Restricted Subsidiary, provided that such
     Indebtedness is contractually subordinated in right of payment to the
     Notes, or Indebtedness of any Subsidiary of the Company that is a
     Restricted Subsidiary to the Company or to any other Wholly-Owned

     the Company or any of its Restricted Subsidiaries incurs Indebtedness to a
     Wholly-Owned Subsidiary of the Company that is a Restricted Subsidiary
     which, at any time after such incurrence, ceases to be a Wholly-Owned
     Subsidiary, then all such Indebtedness in excess of the amount of Allowable
     Subsidiary Loans shall be deemed to have been incurred at the time such
     former Wholly-Owned Subsidiary ceases to be a Wholly-Owned Subsidiary of
     the Company;

     the Company and its Restricted Subsidiaries under such Interest Rate
     Agreements does not exceed the principal amount of such Indebtedness, and
     (b) in the case of Currency Agreements that relate to other Indebtedness,
     such Currency Agreements do not increase the Indebtedness of the Company
     and its Restricted Subsidiaries outstanding at any time other than as a

     effect to the acquisition of such Restricted Subsidiary by the Company;
 
          (xii) Indebtedness of any Restricted Subsidiary existing at the time
     of the designation of such Subsidiary as a Restricted Subsidiary in

     designation such Subsidiary was an Unrestricted Subsidiary, provided that,
     after giving pro forma effect to such designation, such Indebtedness could
     have been incurred by the Company under the limitations set forth in the
     preceding paragraph of this Limitation on Additional Indebtedness covenant
     (assuming for purposes of this clause (xii) only that the Consolidated Cash
     Flow Coverage Ratio set forth in such paragraph were 2.25 to 1.0); and
     provided further that, none of the Company or any of its other Restricted
     Subsidiaries shall provide credit support of any kind (including any
     undertaking, agreement or instrument that would constitute Indebtedness),
     or otherwise be at any time, directly or indirectly liable (as a guarantor
     or otherwise), for such existing Indebtedness, except to the extent the
     Company or any of its Restricted Subsidiaries could become so liable in
     accordance with the provisions of this Limitation on Additional
     Indebtedness covenant (other than solely in accordance with clause (vi)
     above or this clause (xii)).

     arising out of advances on exports, advances on imports, advances on trade
     receivables, factoring of receivables and similar transactions in the
     ordinary course of business and, if secured, secured only by Liens on
     assets of Nortek (UK) Limited and its Subsidiaries and (b) the Company
     under its limited guaranty of not more than $10,000,000 of any such
     Indebtedness of Nortek (UK) Limited and its Subsidiaries;
 
          (xv) other Indebtedness of the Company and its Restricted Subsidiaries
     not to exceed at any time $25,000,000 in aggregate outstanding principal
     amount;
 
        (xvi) Liens permitted under the Limitation on Liens covenant; and
 
          (xvii) Indebtedness ("Refinancing Indebtedness") created, incurred,
     issued, assumed or guaranteed in exchange for, or the proceeds of which are
     used to extend, refinance, renew, replace, substitute or refund
     ("refinance"), Indebtedness described in the preceding paragraph or
     referred to in clauses (i) through (xv) above; provided, however, that (a)
     the principal amount of such Refinancing Indebtedness (or if such
     Refinancing Indebtedness is issued at a price less than the principal
     amount thereof, the original issue amount of such Refinancing
     Indebtedness), together with the principal amount of any remaining
     Indebtedness under the agreement or instrument governing the Indebtedness
     being refinanced, shall not exceed (1) in the case of Refinancing
     Indebtedness incurred to refinance Indebtedness permitted to be incurred
     under any of clauses (iii) through (v) and (xv) above, an amount which,
     when added to all other Indebtedness outstanding under such clause, shall
     not exceed the aggregate amount of Indebtedness permitted to be incurred
     under such clause, and (2) in the case of Refinancing Indebtedness incurred
     to refinance Indebtedness permitted to be incurred under any of clauses
     (i), (ii) and (vi) through (xiii) above, the aggregate amount of such
     Indebtedness outstanding at the time of such refinancing, in each case,
     after giving effect to any mandatory reductions in principal or other
     repayments required under the agreement or instrument governing such
     Indebtedness; (b) such Refinancing Indebtedness shall be subordinated in
     right of payment to the Notes at least to the same
 
                                       23
<PAGE>   25
 
     extent as the Indebtedness to be refinanced; (c) such Refinancing

     be refinanced at the time of such incurrence; (d) the proceeds of such
     Refinancing Indebtedness, if incurred by a Restricted Subsidiary of the
     Company, shall not be used to refinance Indebtedness of the Company or
     another Subsidiary of the Company; and (e) the incurrence of any such
     Refinancing Indebtedness is substantially simultaneous with the refinancing
     of the Indebtedness to be refinanced.
 
     For purposes of this Limitation on Additional Indebtedness covenant, the
accretion of original issue discount on Indebtedness shall not be deemed to be
an incurrence of Indebtedness.
 
     Limitation on Sale or Issuance of Preferred Stock of Restricted
Subsidiaries.  The Company shall not (i) permit any of its Restricted
Subsidiaries to issue or sell to any Person except the Company or a Wholly-Owned
Subsidiary of the Company that is a Restricted Subsidiary any preferred stock of
any Restricted Subsidiary, or (ii) sell or otherwise convey or dispose of, or
permit any of its Wholly-Owned Subsidiaries that is a Restricted Subsidiary to
sell or otherwise convey or dispose of, any such preferred stock so issued or
sold to the Company or any of its Wholly-Owned Subsidiaries that is a Restricted
Subsidiary (except to the issuer thereof, the Company or any of its other
Wholly-Owned Subsidiaries that is a Restricted Subsidiary).
 
     Limitation on Liens.  The Company shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, create, incur, assume or
suffer to exist any Lien on any Principal Property or on any shares of Capital
Stock of any Restricted Subsidiary of the Company held by the Company or any
other Restricted Subsidiary of the Company or on any Indebtedness owed by any
Restricted Subsidiary to the Company or any other Restricted Subsidiary of the
Company. The foregoing limitation does not apply to (i) Liens securing
obligations under the Notes, (ii) Liens securing obligations under the Company
Credit Facility (but such Liens shall not secure Indebtedness in excess of the
amount of Indebtedness then permitted to be incurred under clause (iii) of the
second paragraph of the Limitation on Additional Indebtedness covenant plus the
amount of any Indebtedness then outstanding pursuant to such clause (iii));
(iii) other Liens existing on the Closing Date; (iv) Liens with respect to the
assets of a Restricted Subsidiary granted by such Restricted Subsidiary to the
Company or a Restricted Subsidiary that is a Wholly-Owned Subsidiary of the

(v), (x), (xiii) and (xiv) of the Limitation on Additional Indebtedness
covenant; (vi) Liens granted in connection with the extension, renewal or
refinancing, in whole or in part, of any Indebtedness under the Notes or
described in clause (iii) above; provided that (1) such new Indebtedness is
permitted to be incurred under the Limitation on Additional Indebtedness
covenant and (2) the amount of Indebtedness secured by such Lien is not
increased thereby; and provided, further, that the extension, renewal or
refinancing of Indebtedness of the Company may not be secured by Liens on assets
of any Restricted Subsidiary other than to the extent the Indebtedness being
extended, renewed or refinanced was at any time previously secured by Liens on
assets of such Restricted Subsidiary; and (vii) Permitted Liens.
 
     Limitation on Certain Restrictions Affecting Subsidiaries.  The Company
shall not, and shall not permit any of its Restricted Subsidiaries to, directly
or indirectly, create or enter into or otherwise cause or permit to exist or
become effective any agreement with any Person that would cause any consensual
encumbrance or restriction on the ability of any such Restricted Subsidiary to
(i) pay dividends or make any other distributions on its Capital Stock or any
other interest or participation in, or measured by, its profits, owned by the
Company or any of its Restricted Subsidiaries, (ii) pay or repay any

Interests in such Restricted Subsidiary or (v) guarantee any Indebtedness of the
Company or any other Restricted Subsidiary of the Company except, in each case,
for such encumbrances or restrictions existing under or by reason of (a)
applicable law, (b) the Indenture, (c) customary nonassignment provisions of any
lease governing a leasehold interest of the Company or any of its Restricted
Subsidiaries, (d) any instrument governing Indebtedness of a Person acquired by
the Company or any of its Restricted Subsidiaries at the time of such
acquisition, which encumbrance or restriction is not applicable to
 
                                       24
<PAGE>   26
 
any Person, or the properties or assets of any Person, other than the Person so
acquired, (e) agreements existing as of the issue date of the Original Notes,
(f) the Company Credit Facility, (g) the Broan Limited Credit Facility, (h) any
other agreement pursuant to which any Restricted Subsidiary of the Company
incurs Indebtedness in accordance with the Limitation on Additional Indebtedness
covenant and (i) any agreement effecting a refinancing of Indebtedness issued
pursuant to any agreement or instrument referred to in clause (d), (e), (f), (g)
or (h) above, provided that the terms and conditions of any such encumbrances
and restrictions are not materially less favorable to the Holders than those
under the agreement or instrument evidencing the Indebtedness being refinanced.
 
     The foregoing shall not restrict the ability of any Restricted Subsidiary
of the Company to grant any Lien to the extent otherwise permitted in the
Indenture.
 
     Repurchase upon Change of Control.  See "-- Change of Control" above.
 
     Limitation on Use of Proceeds from Asset Sales.  The Company shall not, and
shall not permit any of its Restricted Subsidiaries to, directly or indirectly,
consummate any Asset Sale unless (i) the Company or such Restricted Subsidiary,
as the case may be, receives consideration at the time of any such Asset Sale
having a value (including the Fair Market Value of any non-cash consideration)
at least equal to the Fair Market Value of the securities or assets being sold
or otherwise disposed of, and (ii) at least 75% of the consideration from such
Asset Sale is received in the form of cash, Cash Equivalents (together with
cash, "Cash Proceeds") or indebtedness for borrowed money of the Company or such
Restricted Subsidiary that is assumed by the transferee of any such assets or
any such indebtedness of any Restricted Subsidiary of the Company whose stock is
purchased by the transferee. Any Net Cash Proceeds (a) in excess of the amount
of cash applied by the Company or any Restricted Subsidiary of the Company
during the period beginning 12 months prior to the date of the Asset Sale (but
not prior to the issue date of the Original Notes) and ending 12 months after
the date of such Asset Sale to purchase any business that is, or any properties
and assets used primarily in, the same or a related business as those owned and
operated by the Company and its Subsidiaries as of the issue date of the
Original Notes or at the date of such Asset Sale and (b) not applied within 12
months after the date of the Asset Sale to reduce Indebtedness of the Company
(other than Indebtedness which is subordinated by its terms to the Notes) or any
Restricted Subsidiary shall be deemed to be "Excess Proceeds." When the
aggregate amount of Excess Proceeds exceeds $15,000,000, the Company shall make
an offer (the "Excess Proceeds Offer") to apply the Excess Proceeds to purchase
the Notes. The Excess Proceeds Offer must be in cash in an amount equal to 100%
of the principal amount plus accrued and unpaid interest, if any, thereon and
Liquidated Damages, if any, to the date fixed for the closing of such offer,
substantially in accordance with the procedures for a Change of Control Offer
described in the Repurchase upon Change of Control covenant. To the extent that
the aggregate amount of Notes tendered pursuant to the Excess Proceeds Offer is
less than the Excess Proceeds, the Company may use the remaining Excess Proceeds
for general corporate purposes and such amounts shall no longer be deemed Excess
Proceeds. If the aggregate principal amount of Notes surrendered by Holders
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to be
purchased on a pro rata basis, subject to the limitation on the authorized
denominations of the Notes.
 
     The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws are applicable in connection with the repurchase of Notes
pursuant to an Excess Proceeds Offer.
 
     Limitation on Transactions with Affiliates.  Except as otherwise permitted
by the Indenture, neither the Company nor any of its Restricted Subsidiaries
shall make any Investment, loan, advance, guaranty or capital contribution to,
or for the benefit of, or sell, lease or otherwise transfer or dispose of any of
its properties or assets to, or for the benefit of, or purchase or lease any
property or assets from, or enter into or amend any contract, agreement or
understanding with, or for the benefit of, any Affiliate of the Company or any
of its Restricted Subsidiaries, unless (i) such transaction or series of
transactions is in the best interests of the Company or such Restricted
Subsidiary based on all relevant facts and circumstances; (ii) such transaction
or series of transactions is fair to the Company or such Restricted Subsidiary
and on terms that are no less favorable to the Company or such Restricted
Subsidiary, as the case may be, than those that could have been
 
                                       25
<PAGE>   27
 
obtained in a comparable transaction on an arms' length basis from a Person that
is not an Affiliate of the Company or any of its Restricted Subsidiaries; and
(iii) (a) with respect to a transaction or series of related transactions
involving aggregate payments in excess of $2,500,000, the Board of Directors and
a majority of the Disinterested Directors shall approve such transaction or
series of transactions by a Board Resolution evidencing their determination that
such transaction or series of transactions complies with clauses (i) and (ii)
above, and (b) with respect to a transaction or series of transactions involving
aggregate payments equal to or greater than $10,000,000, the Company receives a
written opinion from a nationally recognized investment bank or valuation firm
or, with respect to a transaction requiring the valuation of real property, a
nationally recognized real estate appraisal firm, that such transaction or
series of transactions is fair to the Company from a financial point of view.
Certain transactions subject to this covenant, such as the repurchase of Capital
Stock from, or an Investment in, an Affiliate of the Company or any of its
Restricted Subsidiaries may also be subject to the Limitation on Restricted
Payments covenant.
 
     The foregoing limitation shall not apply to: (i) any payment of money or
issuance of securities by the Company or any Restricted Subsidiary of the
Company pursuant to employment agreements or arrangements and employee benefit
plans, including reimbursement or advancement of out-of-pocket expenses and
directors' and officers' liability insurance; (ii) reasonable and customary
payments and other benefits (including indemnification) provided to directors
for service on the Board of Directors of the Company or any of its Restricted
Subsidiaries and reimbursement of expenses related thereto; or (iii)
transactions between the Company and any Restricted Subsidiary of the Company,
or between one Restricted Subsidiary of the Company and another Restricted
Subsidiary of the Company, provided that not more than 20% of such Restricted
Subsidiary is owned by any Affiliate of the Company or any of Restricted
Subsidiaries (other than the Company or a Wholly-Owned Subsidiary of the
Company).
 
     Limitation on Guaranties by Subsidiaries.  The Company shall not permit any
Restricted Subsidiary of the Company, directly or indirectly, to assume,
guarantee or in any other manner become liable with respect to any Indebtedness
of the Company or any Subsidiary Guarantor (other than the Notes), unless (a)
such liability is in respect of the Company Credit Facility or (b) such
Restricted Subsidiary is a Subsidiary Guarantor or simultaneously executes and
delivers (i) to the Company and the Trustee a supplemental indenture to the
Indenture providing for a Subsidiary Guaranty of the Notes by such Restricted
Subsidiary and any other Subsidiary Guarantors having such terms as are set
forth in an exhibit to the Indenture and (ii) to the Trustee a Subsidiary
Guaranty. Notwithstanding the foregoing, in the event that a Subsidiary
Guarantor is released from all obligations which pursuant to the first sentence
of this paragraph obligate it to become a Subsidiary Guarantor, such Subsidiary
Guarantor shall be deemed automatically and unconditionally released from all
obligations under its Subsidiary Guaranty without any further action required on
the part of the Trustee or any Holder. In addition, (i) upon the designation of
any Subsidiary Guarantor as an Unrestricted Subsidiary in compliance with the
terms of the Indenture or (ii) upon any sale or disposition (by merger or
otherwise) of any Subsidiary Guarantor by the Company or a Restricted Subsidiary
of the Company to any Person that is not an Affiliate of the Company or any of
its Restricted Subsidiaries which is otherwise in compliance with the terms of
the Indenture, such Subsidiary Guarantor will be deemed to be released from all
obligations under its Subsidiary Guaranty.
 
     No Lien on the properties or assets of any Restricted Subsidiary of the
Company permitted by the Limitation on Liens covenant shall constitute a
guaranty of the payment of any Indebtedness of the Company for purposes of this
Limitation on Guaranties by Subsidiaries covenant.
 
     The provisions of this Limitation on Guaranties by Subsidiaries covenant
shall cease to have further force and effect (and if there then exists any
Subsidiary Guarantor, such Subsidiary Guarantor will be deemed to be released
from all obligations under its Subsidiary Guaranty) at such time as the similar
covenant in the indenture governing the Company's 9 7/8% Notes shall cease to
have further force and effect (whether by reason of amendment, redemption or
repayment of such Indebtedness or otherwise), provided, however, that if the
instrument or other agreement governing any Indebtedness incurred to refinance
the 9 7/8% Notes includes such a similar covenant, the provisions of this
Limitation on Guaranties by Subsidiaries covenant shall continue in full force
and effect for so long as such similar covenant remains in force and effect.
 
                                       26
<PAGE>   28
 
     Payments for Consents.  Neither the Company nor any of its Subsidiaries
shall, directly or indirectly, pay or cause to be paid any consideration whether
by way of interest, fee or otherwise, to any Holder of any Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of the Indenture or the Notes unless such consideration is offered to be paid or
agreed to be paid to all Holders of the Notes which so consent, waive or agree
to amend in the time frame set forth in solicitation documents relating to such
consent, waiver or agreement.
 
     Provision of Reports.  The Indenture provides that whether or not required
by the rules and regulations of the Commission, so long as any Notes are
outstanding, the Company will furnish to the Holders of Notes (i) all quarterly
and annual financial information that would be required to be contained in a
filing with the Commission on Forms 10-Q and 10-K if the Company were required
to file such Forms, including a "Management's Discussion and Analysis of
Financial Condition and Results of Operations" that describes the financial
condition and results of operations of the Company and its Subsidiaries and,
with respect to the annual information only, a report thereon by the Company's
independent certified public accountants and (ii) all reports that would be
required to be filed with the Commission on Form 8-K if the Company were
required to file such reports. In addition, whether or not required by the rules
and regulations of the Commission, the Company will file a copy of all such
information with the Commission for public availability (unless the Commission
will not accept such a filing) and make such information available to investors
or prospective investors who request it in writing.
 
MERGER, CONSOLIDATION OR TRANSFER OF ASSETS
 
     The Company shall not consolidate with, merge with or into, or transfer all
or substantially all of its assets (as an entirety or substantially as an
entirety in one transaction or a series of related transactions) to, any Person
or permit any Person to merge with or into it, or permit any of its Subsidiaries
to enter into any such transaction or transactions if such transaction or
transactions in the aggregate would result in a transfer of all or substantially
all of the assets of the Company and its Subsidiaries on a consolidated basis,
unless: (1) the Company shall be the continuing Person, or the Person, if other
than the Company, formed by such consolidation or into which the Company is
merged or to which the properties and assets of the Company or of the Company
and its Subsidiaries on a consolidated basis, substantially as an entirety, are
transferred shall be a corporation organized and existing under the laws of the
United States or any state thereof or the District of Columbia and shall
expressly assume, by an indenture supplemental to the Indenture, executed and
delivered to the Trustee, in form satisfactory to the Trustee, all the
obligations of the Company under the Notes and the Indenture, and the Indenture
remains in full force and effect; (2) immediately before and immediately after
giving effect to such transaction, no Event of Default and no Default shall have
occurred and be continuing; (3) the Person which is formed by or survives such
consolidation or merger or to which such assets are transferred (the "surviving
entity"), after giving pro forma effect to such transaction, could incur $1.00
of additional Indebtedness under the first paragraph of the Limitation on
Additional Indebtedness covenant; (4) immediately after giving effect to such
transaction on a pro forma basis the Consolidated Net Worth of the surviving
entity shall be equal to or greater than the Consolidated Net Worth of the
Company immediately before such transaction; and (5) each Subsidiary Guarantor,
if any, unless it is the other party to the applicable transaction described
above or its Subsidiary Guaranty, after giving effect to such transaction, is to
be released in accordance with the terms hereof and of such Subsidiary Guaranty,
shall have confirmed by supplemental indenture that its Subsidiary Guaranty
shall apply to the obligations of the Company or the surviving entity under the
Indenture.
 
     In connection with any such consolidation, merger or transfer, the Company
shall deliver, or cause to be delivered, to the Trustee, in form and substance
reasonably satisfactory to the Trustee, an Officers' Certificate and an opinion
of counsel, each stating that such consolidation, merger or transfer and the
supplemental indenture in respect thereto comply with the Indenture and that all
conditions precedent therein provided for relating to such transactions have
been complied with.
 
     Upon any consolidation or merger, or any transfer of all or substantially
all of the assets of the Company and its Subsidiaries on a consolidated basis,
in accordance with the second preceding paragraph, the successor Person formed
by such consolidation or into which the Company is merged or the successor
Person to which
 
                                       27
<PAGE>   29
 
such transfer is made shall succeed to, and be substituted for, and may exercise
every right and power of, the Company under the Indenture with the same effect
as if such successor Person had been named as the Company in the Indenture, and
when a successor Person assumes all the obligations of its predecessor under the
Indenture or the Notes, the predecessor shall be released from those
obligations; provided, however, that in the case of a transfer by lease, the
predecessor shall not be released from the payment of principal of, premium, if
any, interest and Liquidated Damages, if any, on the Notes.
 
     With respect to the transfer of all or substantially all of the assets of
the Company or of the assets of the Company and its Subsidiaries on a
consolidated basis, there is no precise established definition of the term
"substantially all" under applicable law. Accordingly, if the Company were to
engage in transactions in which it disposed of less than all of its assets or
the Company or a Subsidiary of the Company were to engage in transactions in
which less than all of the assets of the Company and its Subsidiaries on a
consolidated basis were disposed of, a question could arise as to whether such
disposition was of "substantially all" of the assets of the Company or of the
Company and its Subsidiaries on a consolidated basis, as the case may be, and,
therefore, whether the transaction was subject to the foregoing provisions of
the Indenture.
 
EVENTS OF DEFAULT AND REMEDIES
 
     The Indenture provides that each of the following constitutes an "Event of
Default": (1) the Company defaults in the payment, when due and payable, of (i)
interest on and Liquidated Damages, if any, with respect to any Note and the
default continues for a period of 30 days, or (ii) principal of or premium, if
any, on any Notes when the same becomes due and payable at maturity, by
acceleration, on the Redemption Date, on the Change of Control Payment Date, on
any payment date respecting an Excess Proceeds Offer or otherwise; (2) the
Company fails to comply with any of the provisions set forth under "Merger,
Consolidation or Transfer of Assets" above; (3) the Company fails to comply with
any of its covenants or agreements in the Notes or the Indenture (other than
those referred to in clause (1) or (2) above), or any Subsidiary Guarantor fails
to comply with any of its covenants or agreements in the Indenture or its
Subsidiary Guaranty, and in either case such failure continues for the period
and after receipt by the Company of the notice specified below; (4) 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 of its Restricted Subsidiaries (or the payment of which is
guaranteed by the Company or any of its Restricted Subsidiaries), whether such
indebtedness or guaranty is now existing or hereafter created, if such default
shall constitute a failure to pay any portion of the principal of such
indebtedness when due and payable or if as a result of such default the maturity
of such indebtedness has been accelerated prior to its stated maturity and, in
either case, the principal amount of such indebtedness, together with the
principal amount of any other such indebtedness for money borrowed which has not
been paid when due and payable or the maturity of which has been accelerated as
a result of such default, aggregates $15,000,000 or more; (5) the Company or any
of its Significant Subsidiaries that is a Restricted Subsidiary (or any group of
Restricted Subsidiaries that, taken together, would constitute a Significant
Subsidiary) pursuant to or within the meaning of any bankruptcy law: (A)
commences a voluntary case or proceeding; (B) consents to the entry of an order
for relief against it in an involuntary case or proceeding; (C) consents to the
appointment of a custodian of it or for all or substantially all of its
property; (D) makes a general assignment for the benefit of its creditors; or
(E) admits in writing its inability to pay its debts generally as they become
due; (6) 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
Significant Subsidiaries that is a Restricted Subsidiary (or any group of
Restricted Subsidiaries that, taken together, would constitute a Significant
Subsidiary) in an involuntary case or proceeding; (B) appoints a custodian of
the Company or any of its Significant Subsidiaries that is a Restricted
Subsidiary (or any group of Restricted Subsidiaries that, taken together, would
constitute a Significant Subsidiary) for all or substantially all of its
properties; (C) orders the liquidation of the Company or any of its Significant
Subsidiaries that is a Restricted Subsidiary (or any group of Restricted
Subsidiaries that, taken together, would constitute a Significant Subsidiary)
and (D) remains unstayed and in effect for 60 days; (7) final judgments for the
payment of money which in the aggregate exceed $15,000,000 shall be rendered
against the Company or any of its Restricted Subsidiaries by a court and shall
remain unstayed or undischarged for a period of 60 days; or (8) any Subsidiary
Guaranty ceases to be in full force and effect or is declared null and void, or
any Subsidiary
 
                                       28
<PAGE>   30
 
Guarantor denies that it has any further liability under any Subsidiary Guaranty
or gives notice to such effect (in each case other than by reason of the
termination of the Indenture or the release of such Subsidiary Guaranty in
accordance with the terms of the Indenture and such Subsidiary Guaranty) and
such condition shall have continued for the period and after receipt by the
Company of the notice specified below.
 
     A Default under clause (3) or (8) above is not an Event of Default until
the Trustee notifies the Company, or the Holders of at least 25% in aggregate
principal amount of the Notes at the time outstanding notify the Company and the
Trustee, of the Default and the Company does not cure such Default within 30
days after receipt of such notice. Any such notice must specify the Default,
demand that it be remedied and state that such notice is a "Notice of Default."
 
     In the case of any Event of Default (other than as a result of the failure
to comply with the Repurchase upon Change of Control covenant) occurring by
reason of any willful action (or inaction) taken (or not taken) by or on behalf
of the Company with the intention of avoiding payment of the premium which the
Company would have to pay if the Company then had elected to redeem the Notes,
an equivalent premium shall also become and be immediately due and payable to
the extent permitted by law, anything in the Indenture or in the Notes contained
to the contrary notwithstanding.
 
     In the case of an Event of Default as a result of a failure to comply with
the Repurchase upon Change of Control covenant occurring by reason of any
willful action (or inaction) taken (or not taken) by or on behalf of the Company
with the intention of avoiding payment of the premium which the Company would
have to pay pursuant to the Repurchase upon Change of Control covenant, such
premium shall also become and be immediately due and payable at such time as the
principal and interest on the Notes become due and payable pursuant to the
acceleration provisions of the Indenture to the extent permitted by law,
anything in the Indenture or in the Notes contained to the contrary
notwithstanding.
 
     If any Event of Default (other than an Event of Default specified in clause
(5) or (6) above) occurs and is continuing, the Trustee or the Holders of at
least 25% of the principal amount of the Notes then outstanding, by written
notice to the Company (and to the Trustee if such notice is given by such
Holders), may, and such Trustee at the request of such Holders shall, declare
all unpaid principal of, premium, if any, and accrued interest on and Liquidated
Damages, if any, with respect to the Notes to be due and payable immediately. If
an Event of Default specified in clause (5) or (6) above occurs, all unpaid
principal of, premium, if any, and accrued interest on and Liquidated Damages,
if any, with respect to the Notes then outstanding shall ipso facto become and
be immediately due and payable without declaration or other act on the part of
the Trustee or any Holder. The Holders of at least a majority in principal
amount of the Notes then outstanding by written notice to the Trustee may
rescind an acceleration and its consequences (except an acceleration due to
default in payment of principal of, premium, if any, and accrued interest on and
Liquidated Damages, if any, with respect to, the Notes) if all existing Events
of Default have been cured or waived except non-payment of principal of,
premium, if any, and accrued interest on and Liquidated Damages, if any, with
respect to, the Notes that have become due solely because of the acceleration.
Subject to certain restrictions set forth in the Indenture, the Holders of at
least a majority in principal amount of the outstanding Notes by notice to the
Trustee may waive an existing Default or Event of Default and its consequences,
except a default in the payment of principal of, premium, if any, or interest on
and Liquidated Damages, if any, with respect to any Note or a Default under a
provision which requires consent of all Holders to amend. When a Default or
Event of Default is waived, it is cured and ceases. A Holder of Notes may not
pursue any remedy with respect to the Indenture or the Notes unless: (i) the
Holder gives to the Trustee written notice that an Event of Default is
continuing; (ii) the Holders of at least 25% in aggregate principal amount of
any Notes outstanding make a written request to the Trustee to pursue the
remedy; (iii) such Holder or Holders offer to the Trustee reasonable indemnity
or security against any loss, liability or expense satisfactory to the Trustee;
(iv) the Trustee does not comply with the request within 30 days after receipt
of the request and the offer of indemnity or security; and (v) during such
30-day period the Holders of a majority in aggregate principal amount of the
outstanding Notes do not give the Trustee a direction which is inconsistent with
the request.
 
                                       29
<PAGE>   31
 
DISCHARGE OF THE INDENTURE AND THE NOTES
 
     If, at any time prior to the Stated Maturity of the Notes or the date of
redemption of all outstanding Notes, the Company irrevocably deposits with the
Trustee money and/or 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, maturing as to principal and interest in such amounts and at such times
as are sufficient, without consideration of any reinvestment of such interest,
to pay principal of, premium, if any, and accrued interest on and Liquidated
Damages, if any, with respect to, the outstanding Notes (other than replaced
Notes) to maturity or redemption, as the case may be, in accordance with the
terms of the Indenture and the Notes, the Indenture and each Subsidiary
Guaranty, if any, shall cease to be of further effect as to all outstanding
Notes (except, among other things, as to (i) remaining rights of registration of
transfer and substitution and exchange of the Notes, (ii) rights of Holders to
receive payment of principal of, premium, if any, and accrued interest on and
Liquidated Damages, if any, with respect to the Notes, and (iii) the rights,
obligation and immunities of the Trustee).
 
TRANSFER AND EXCHANGE
 
     A Holder may transfer or exchange Notes in accordance with the Indenture.
The Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents, and to pay any taxes and fees required by
law or permitted by the Indenture. The Registrar is not required to transfer or
exchange any Note selected for redemption. Also, the Registrar is not required
to transfer or exchange any Note for a period of 15 days before a selection of
Notes to be redeemed.
 
     The registered Holder of a Note will be treated as the owner of it for all
purposes.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
     Subject to certain exceptions, with the written consent of the Holders of
at least a majority in aggregate principal amount of the Notes then outstanding,
the Company and the Trustee may amend the Indenture or the Notes, or may waive
compliance by the Company or any Subsidiary Guarantor with any provision of the
Indenture, the Notes or such Subsidiary Guarantor's Subsidiary Guaranty.
However, without the consent of each Holder affected, a waiver or an amendment
to the Indenture or the Notes may not: (i) reduce the percentage of principal
amount of the Notes whose Holders must consent to an amendment or waiver; (ii)
make any change to the Stated Maturity of the principal of, premium, if any, or
any interest on or Liquidated Damages, if any, with respect to, the Notes or any
Redemption Price thereof, or impair the right to institute suit for the
enforcement of any such payment or make any Note payable in money or securities
other than that stated in the Note; (iii) waive a default in the payment of the
principal of, premium, if any, or interest on and Liquidated Damages, if any,
with respect to, any Note; (iv) make any change in the provisions of the
Repurchase upon Change of Control covenant or the Limitation on Use of Proceeds
of Asset Sales covenant; (v) release any Subsidiary Guarantor from any of its
obligations under its Subsidiary Guaranty or the Indenture other than in
compliance with the terms of the Indenture and such Subsidiary Guaranty; or (vi)
make any change in the amendment provisions of the Indenture.
 
     Notwithstanding the foregoing, without the consent of any Holder, the
Company and the Trustee may amend or supplement the Indenture or the Notes (i)
to cure any ambiguity, defect or inconsistency; (ii) to comply with the
provisions described under "Merger, Consolidation or Transfer of Assets"; (iii)
to provide for uncertificated Notes in addition to or in place of certificated
Notes so long as such uncertificated Notes are in registered form for purposes
of the Internal Revenue Code of 1986, as amended; (iv) to make any other change
that does not adversely affect the rights of any Holder; (v) to comply with any
requirement of the Commission in connection with the qualification of the
Indenture under the Trust Indenture Act; or (vi) to add any Subsidiary of the
Company as a Subsidiary Guarantor.
 
CONCERNING THE TRUSTEE
 
     State Street Bank and Trust Company is the Trustee under the Indenture and
has been appointed by the Company as Registrar and Paying Agent with respect to
the Notes.
 
                                       30
<PAGE>   32
 
     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize certain property received in respect of any such
claim as security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest it must eliminate
such conflict within 90 days, or apply to the Commission for permission to
continue or resign.
 
     The Holders of not less than a majority in principal amount of the then
outstanding Notes will have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to the Trustee,
subject to certain exceptions. The Indenture provides that in case an Event of
Default shall occur and be continuing (and shall not be cured), the Trustee will
be required, in the exercise of its power, to use the degree of care and skill
of a prudent person in the conduct of his own affairs. Subject to such
provisions, the Trustee will be under no obligation to exercise any of its
rights or powers under the Indenture at the request of any Holders of Notes,
unless they shall have offered to the Trustee reasonable security or indemnity
satisfactory to it against any loss, liability or expense.
 
CERTAIN DEFINITIONS
 
     Set forth below are certain defined terms used in the Indenture. Reference
is made to the Indenture for full disclosure of all such terms, as well as any
other capitalized terms used herein for which no definition is provided.
 
     "Acquired Indebtedness" means, with respect to any Person, Indebtedness of
such Person (i) assumed in connection with an acquisition of assets or
properties from such Person or (ii) existing at the time such Person becomes a
Restricted Subsidiary of any other Person provided such Person was not
immediately prior thereto an Unrestricted Subsidiary (in each case other than
any Indebtedness incurred in connection with, or in contemplation of, such
acquisition or such Person becoming such a Restricted Subsidiary).
 
     "Affiliate" means, with respect to any Person, any other Person directly or

or Indebtedness is due and payable, including pursuant to any mandatory
redemption provision (but excluding any provision providing for the repurchase

     "Subsidiary" of any Person means any corporation, partnership, association

Capital Stock or Indebtedness of, or own or hold any Lien on any property of,
the Company or any other Restricted Subsidiary of the Company that is not a

which neither the Company nor any of its Restricted Subsidiaries has any direct

BOOK-ENTRY, DELIVERY AND FORM
 
     The certificates representing Exchange Notes will be issued in fully
registered form, without coupon. Except as described below, the Exchange Notes
will be deposited with, or on behalf of, the Depositary and registered in the
name of Cede & Co., as nominee of the Depositary (such nominee being referred to
herein as the "Global Note Holder") in the form of one or more Global Notes (the
"Global Notes") or will remain in the custody of the Trustee.
 
     Exchange Notes that are issued as described below under "-- Certificated
Securities" will be issued in registered form (the "Certificated Securities").
Upon the transfer of Certificated Securities, such Certificated Securities may,
unless the Global Notes have previously been exchanged for Certificated
Securities, be exchanged for an interest in a Global Note representing the
principal amount of Notes being transferred.
 
     The Depositary is a limited-purpose trust company which was created to hold
securities for its participating organizations (collectively, the "Participants"
or the "Depositary's Participants") and to facilitate the clearance and
settlement of transactions in such securities between Participants through
electronic book-entry changes in accounts of its Participants. The Depositary's
Participants include securities brokers and dealers (including the Initial
Purchasers), banks and trust companies, clearing corporations and certain other
organizations. Access to the Depositary's system is also available to other
entities such as banks, brokers, dealers and trust companies (collectively, the
"Indirect Participants" or the "Depositary's Indirect Participants") that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly. Persons who are not Participants may beneficially own securities
held by or on behalf of the Depositary only through the Depositary's
Participants or the Depositary's Indirect Participants.
 
     The Company expects that pursuant to procedures established by the
Depositary (i) upon deposit of the Global Notes, the Depositary will credit the
accounts of Participants designated by the Initial Purchasers with portions of
the principal amount of the Global Notes and (ii) ownership of the Exchange
Notes evidenced by the Global Notes will be shown on, and the transfer of
ownership thereof will be effected only through, records maintained by the
Depositary (with respect to the interests of the Depositary's Participants), the
Depositary's Participants and the Depositary's Indirect Participants.
Prospective purchasers are advised that the laws of some states require that
certain Persons take physical delivery in definitive form of securities that
they own. Consequently, the ability to transfer Exchange Notes evidenced by the
Global Notes will be limited to such extent.
 
     So long as the Global Note Holder is the registered owner of any Exchange
Notes, the Global Note Holder will be considered the sole owner or holder of
such Exchange Notes outstanding under the Indenture. Beneficial owners of
Exchange Notes evidenced by the Global Note will not be considered the owners or
Holders thereof under the Indenture for any purpose, including with respect to
the giving of any directions, instructions or approvals to the Trustee
thereunder. The ability of a Person having a beneficial interest in Exchange
Notes represented by a Global Note to pledge such interest to Persons or
entities that do not participate in the Depositary's system or to otherwise take
actions in respect of such interest may be affected by the lack of physical
certificate evidencing such interest.
 
     Neither the Company nor the Trustee will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of Exchange Notes by the Depositary, or for maintaining, supervising or
reviewing any records of the Depositary relating to such Exchange Notes.
 
     Payments in respect of the principal of, premium, if any, and Liquidated
Damages, if any, with respect to, any Notes registered in the name of a Global
Note Holder on the applicable record date will be payable by the Trustee to or
at the direction of such Global Note Holder in its capacity as the registered
holder under the Indenture. Under the terms of the Indenture, the Company and
the Trustee may treat the Persons in whose names the Notes, including the Global
Notes, are registered as the owners thereof for the purpose of receiving such
payments and for any and all other purposes whatsoever. Consequently, neither
the Company nor the Trustee has or will have any responsibility or liability for
the payment of such amounts to beneficial owners of Notes (including principal,
premium, if any, interest and Liquidated Damages, if any).
 
                                       41
<PAGE>   43
 
     The Company believes, however, that it is currently the policy of the
Depositary to immediately credit the accounts of the relevant Participants with
such payment, in amounts proportionate to their respective holdings in principal
amount of beneficial interests in the relevant security as shown on the records
of the Depositary. Payments by the Depositary's Participants and the
Depositary's Indirect Participants to the beneficial owners of Exchange Notes
will be governed by standing instructions and customary practice and will be the
responsibility of the Depositary's Participants or the Depositary's Indirect
Participants.
 
CERTIFICATED SECURITIES
 
     Subject to certain conditions, any Person having a beneficial interest in a
Global Note may, upon request to the Company or the Trustee, exchange such
beneficial interest for Exchange Notes in the form of Certificated Securities.
Upon any such issuance, the Trustee is required to register such Exchange Notes
in the name of, and cause the same to be delivered to, such Person or Persons.
In addition, if (i) the Company notifies the Trustee in writing that the
Depositary is no longer willing or able to act as a depositary and the Company
is unable to appoint a qualified successor within 90 days or (ii) the Company,
at its option, notifies the Trustee in writing that it elects to cause the
issuance of Exchange Notes in the form of Certificated Securities under the
Indenture, then, upon surrender by the relevant Global Note Holder of its Global
Note, Exchange Notes in such form will be issued to each Person that the
Depositary identifies as the beneficial owner of the related Exchange Notes.
 
     Neither the Company nor the Trustee shall be liable for any delay by the
Depositary in identifying the beneficial owners of the related Exchange Notes
and each such Person may conclusively rely on, and shall be protected in relying
on, instructions from the Depositary for all purposes (including with respect to
the registration and delivery, and the respective principal amounts, of the
Notes to be issued).
 
SAME-DAY SETTLEMENT AND PAYMENT
 
     The Indenture requires that payments in respect of the Exchange Notes
(including principal, premium, if any, interest, if any) be made by wire
transfer of immediately available funds to the accounts specified by the Global
Note Holder. Secondary trading in long-term notes and debentures of corporate
issuers is generally settled in clearing-house or next-day funds. In contrast,
the Notes have been designated as eligible for trading in the PORTAL market and
are expected to trade in the Depositary's Next-Day Funds Settlement System, and
any permitted secondary market trading activity in the Notes will therefore be
required by the Depositary to be settled in immediately available funds. The
Company expects that secondary trading in the Certificated Notes also will be
settled in immediately available funds.

                               THE EXCHANGE OFFER
 
REGISTRATION RIGHTS; LIQUIDATED DAMAGES
 
     The Company and the Initial Purchasers entered into the Registration Rights
Agreement on March 17, 1997 (the "Closing Date"). Pursuant to the Registration
Rights Agreement, the Company agreed to use its best efforts to cause to be
filed with the Commission the Exchange Offer Registration Statement, of which
this Prospectus forms a part, on the appropriate form under the Securities Act
with respect to an offer to exchange the Original Notes for Exchange Notes. The
Exchange Notes will be substantially identical to the Original Notes, except
that the Exchange Notes will not contain terms with respect to transfer
restrictions (other than those that might be imposed by state securities laws)
or, except as arising out of the obligations set forth in the next sentence,
provide for the payment of Liquidated Damages. In the event that (i) the Company
is not permitted to commence or accept tenders pursuant to the Exchange Offer
because the Exchange Offer is not permitted by applicable law or Commission
policy, (ii) any Holder of Transfer Restricted Securities notifies the Company
within 20 business days after the consummation of the Exchange Offer that (a) it
is prohibited by law or Commission policy from participating in the Exchange
Offer or (b) that it may not resell the Exchange Notes acquired by it in the
Exchange Offer to the public without delivering a prospectus and the prospectus
contained in the Exchange Offer Registration Statement is not appropriate or
available for such resales or (c) that it is a broker-dealer and owns Original
Notes acquired directly from the Company or an Affiliate of the Company, the
Company will file with the Commission a Shelf Registration Statement (as defined
above under "Description of Notes -- Certain Definitions") to cover resales of
the Original Notes by the Holders thereof who satisfy certain conditions
relating to the provision of information in connection with the Shelf
Registration Statement. The Company will use its best efforts to cause the
applicable registration statement to be declared effective as promptly as
possible by the Commission. For purposes of the foregoing, "Transfer Restricted
Securities" means each Original Note until (i) the date on which such Original
Note has been exchanged by a Person other than a broker-dealer for an Exchange
Note in the Exchange Offer, (ii) following the exchange by a Participating
Broker-Dealer in the Exchange Offer of an Original Note for an Exchange Note,
the date on which such Exchange Note is sold to a purchaser who receives from
such Participating Broker-Dealer on or prior to the date of such sale a copy of
the prospectus contained in the Exchange Offer Registration Statement, (iii) the
date on which such Original Note has been effectively registered under the
Securities Act and disposed of in accordance with the Shelf Registration
Statement or (iv) the date on which such Original Note is distributed to the
public pursuant to Rule 144 under the Securities Act.
 
     This Prospectus covers the offer and sale of the Exchange Notes pursuant to
the Exchange Offer made hereby and the resale of Exchange Notes received in the
Exchange Offer by any Participating Broker-Dealer who holds Original Notes
(other than Original Notes acquired directly from the Company or one of its
affiliates).
 
     Under existing interpretations by the staff of the Commission, the Exchange
Notes would, in general, be freely transferable after the Exchange Offer without
further registration under the Securities Act; provided, that Participating
Broker-Dealers receiving Exchange Notes in the Exchange Offer will have a
prospectus delivery requirement with respect to the resales of Exchange Notes.
The Commission has taken the position that such Participating Broker-Dealers may
fulfill their prospectus delivery requirements with respect to the Exchange
Notes (other than a resale of an unsold allotment from the original sale of
Original Notes) with the prospectus contained in the Exchange Offer Registration
Statement. The Company has agreed, for a period of 180 days after consummation
of the Exchange Offer, to make available a prospectus meeting the requirements
of the Securities Act to any Participating Broker-Dealer for use in connection
with any resale of any Exchange Notes acquired.
 
     Each Holder (other than certain specified holders) who wishes to exchange
such Original Notes for Exchange Notes in the Exchange Offer will be required to
make certain representations, including representations that (i) any Exchange
Notes to be received by it will be acquired in the ordinary course of its
business, (ii) at the time of the commencement of the Exchange Offer, it had no
arrangement with any Person
 
                                       43
<PAGE>   45
 
to participate in the distribution (within the meaning of the Securities Act) of
the Exchange Notes and (ii) is not an "affiliate," as defined in Rule 405 of the
Securities Act, of the Company.
 
     The Registration Rights Agreement provides that, to the extent not
prohibited by any applicable law or applicable interpretation of the staff of
the Commission, (i) the Company will use its best efforts to cause to be filed
with the Commission an Exchange Offer Registration Statement on or prior to 45
days after the Closing Date, (ii) the Company will use its best efforts to have
such Exchange Offer Registration Statement declared effective under the
Securities Act by the Commission on or prior to 120 days after the Closing Date,
(iii) the Company will use its best efforts to cause the Exchange Offer to be
consummated on or prior to 45 days after the date on which the Exchange Offer
Registration Statement was declared effective under the Securities Act by the
Commission and (iv) if obligated to cause to be filed with the Commission the
Shelf Registration Statement, the Company will cause to be filed with the
Commission a Shelf Registration Statement on or prior to 45 days after such
filing obligation arises and use its best efforts to cause the Shelf
Registration Statement to be declared effective by the Commission on or prior to
90 days after such obligation arises; provided, that if the Company has not
consummated the Exchange Offer within 165 days of the Closing Date, then the
Company will cause to be filed with the Commission a Shelf Registration
Statement on or prior to the 210th day after the Closing Date. The Company shall
use its reasonable best efforts to keep such Shelf Registration Statement
continuously effective, supplemented and amended until the second anniversary of
the Closing Date or such shorter period that will terminate when all the
securities covered by the Shelf Registration Statement have been sold pursuant
to the Shelf Registration Statement. If (a) the Company fails to file any
Registration Statement required by the Registration Rights Agreement on or prior
to the date specified for such filing, (b) any such Registration Statement is
not declared effective by the Commission on or prior to the date specified for
such effectiveness (the "Effectiveness Target Date"), (c) the Company fails to
consummate the Exchange Offer on or prior to 45 days after the Effectiveness
Target Date with respect to the Exchange Offer Registration Statement, or (d)
the Shelf Registration Statement or the Exchange Offer Registration Statement is
declared effective but thereafter ceases to be effective or usable during the
periods specified in the Registration Rights Agreement (each such event referred
to in clauses (a) through (d) above a "Registration Default"), then the Company
will be required to pay Liquidated Damages to each Holder affected by such
Registration Default on each interest payment date. Liquidated Damages shall
accrue from and after the date of each Registration Default, and shall continue
to accrue thereafter until such Registration Default has been cured or waived as
set forth in the Registration Rights Agreement, at a rate equal to 0.50% per
annum of the principal amount of Notes during the first 90-day period
immediately following the occurrence of such Registration Default, which rate
shall increase by an additional 0.50% per annum during each subsequent 90-day
period up to a maximum rate equal to 2.0% per annum.
 
     The summary herein of certain provisions of the Registration Rights
Agreement does not purport to be complete and is subject to, and is qualified in
its entirety by reference to, all the provisions of the Registration Rights
Agreement, a copy of which is filed as an exhibit to this Exchange Offer
Registration Statement. See "Available Information."
 
     Except as set forth above, after consummation of the Exchange Offer,
holders of Original Notes have no registration or exchange rights under the
Registration Rights Agreement. See "-- Consequences of Failure to Exchange," and
"-- Resales of Exchange Notes; Plan of Distribution."
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     The Original Notes which are not exchanged for Exchange Notes pursuant to
an Exchange Offer and are not included in a resale prospectus will remain
restricted securities. Accordingly, such Original Notes may be offered, sold or
otherwise transferred prior to the date which is two years after the later of
the date of original issue and the last date that the Company or any affiliate
of the Company was the owner of such securities (or any predecessor thereto)
(the "Resale Restriction Termination Date") only (a) to the Company (b) pursuant
to a registration statement which has been declared effective under the
Securities Act, (c) for so long as the Original Notes are eligible for resale
pursuant to Rule 144A, to a person the owner reasonably believes is a qualified
institutional buyer that purchases for its own account or for the account of a
qualified institutional buyer to whom notice is given that the transfer is being
made in reliance on Rule 144A, (d) to an "accredited
 
                                       44
<PAGE>   46
 
investor" within the meaning of subparagraph (1), (2), (3) or (7) of paragraph
(a) of Rule 501 under the Securities Act that is purchasing for his own account
or for the account of such an "accredited investor" in each case in a minimum of
Original Notes with a purchase price of $500,000 or (c) pursuant to any other
available exemption from the registration requirements of the Securities Act,
subject in each of the foregoing cases to any requirement of law that the
disposition of its property or the property of such investor account or accounts
be at all times within its or their control. The foregoing restrictions on
resale will not apply subsequent to the Resale Restriction Termination Date. If
any resale or other transfer of the Original Notes is proposed to be made
pursuant to clause (d) above prior to the Resale Restriction Termination Date,
the transferor shall deliver a letter from the transferee to the Company and the
Trustee, which shall provide, among other things, that the transferee is an
"accredited investor" within the meaning of subparagraph (1), (2), (3) or (7) of
paragraph (a) of Rule 501 under the Securities Act and that it is acquiring such
Securities for investment purposes and not for distribution in violation of the
Securities Act. Prior to any offer, sale or other transfer of Original Notes
prior to the Resale Restriction Termination Date pursuant to clauses (d) or (e)
above, the issuer and the Trustee may require the delivery of an opinion of
counsel, certifications and/or other information satisfactory to each of them.
 
TERMS OF THE EXCHANGE OFFER
 
     Upon the terms and subject to the conditions set forth in this Prospectus
and in the accompanying Letter of Transmittal, the Company will accept all
Original Notes properly tendered and not withdrawn prior to the applicable
Expiration Date. The Company will issue $1,000 principal amount of Exchange
Notes in exchange for each $1,000 principal amount of outstanding Original Notes
accepted in the Exchange Offer. Holders may tender some or all of their Original
Notes pursuant to the Exchange Offer. However, Original Notes may be tendered
only in integral multiples of $1,000 principal amount at final maturity.
 
     The forms and terms of the Exchange Notes are the same as the form and
terms of the Original Notes, except that (i) the Exchange Notes bear a Series B
designation, (ii) the Exchange Notes have been registered under the Securities
Act and therefore will generally not bear legends restricting their transfer
(except as may be required under state securities laws) pursuant to the
Securities Act, and (iii) the holders of Exchange Notes will generally not be
entitled to rights under the Registration Rights Agreement including the
provisions providing for liquidated damages, in certain circumstances relating
to the timing of the Exchange Offer, which rights will terminate when the
Exchange Offer is consummated. The Exchange Notes will evidence the same debt as
the Original Notes (which they replace), and will be issued under, and be
entitled to the benefits of, the Indenture.
 
     Solely for reasons of administration (and for no other purpose) the Company
has fixed the close of business on             , 1997 as the record date for the
Exchange Offer for purpose of determining the persons to whom this Prospectus
and the Letter of Transmittal will be mailed initially. Only a registered holder
of Original Notes (or such holder's legal representative or attorney-in-fact) as
reflected on the records of the trustee under the governing indenture may
participate in the Exchange Offer. There will be no fixed record date for
determining registered holders of the Original Notes entitled to participate in
the relevant Exchange Offer.
 
     Holders of the Original Notes do not have any appraisal or dissenters'
rights under the General Corporation Law of Delaware or under the Indenture 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 Original
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 of Original Notes for the purpose of receiving Exchange Notes.
 
     If any tendered Original Notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, certificates for any such unaccepted Original Notes will be returned,
without expenses, to the tendering holder thereof as promptly as practicable
after the Expiration Date.

<PAGE>   47
 
     Holders of Original Notes who tender 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
Original Notes pursuant to the Exchange Offer. The Company will pay all charges
and expenses, other than certain applicable taxes, in connection with the
Exchange Offer. See "--Fees and Expenses."
 
EXPIRATION DATES; EXTENSIONS; AMENDMENTS
 
     The term "Expiration Date" shall mean 5:00 p.m. New York City time on
            , 1997 unless the Company, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date to which the Exchange Offer is extended.
 
     In order to extend the Expiration Date, the Company will notify the
Exchange Agent of any extension by oral or written notice and will make a public
announcement thereof, prior to 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date.
 
     The Company reserves the right in its sole discretion (i) to delay
acceptance of any Original Notes, (ii) to extend the Exchange Offer (iii) if the
condition set forth below under "-- Conditions of the Exchange Offer" shall not
have been satisfied, to terminate the Exchange Offer by giving oral or written
notice of such delay, extension or termination to the Exchange Agent, or (iv) 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 a public announcement thereof. If the Exchange Offer is amended
in a manner determined by the Company to constitute a material change, the
Company will promptly disclose such amendment by means of a prospectus
supplement that will be distributed to the registered holders of the Original
Notes and the Exchange Offer will be extended for a period of five to ten
business days, as required by law, depending upon the significance of the
amendment and the manner of disclosure to the registered holders, if the
Exchange Offer would otherwise expire during such five to ten business day
period.
 
     Without limiting the manner in which the Company may choose to make public
announcements of any delay in acceptance, extension, termination or amendment of
the Exchange Offer, the Company shall have no obligation to publish, advertise,
or otherwise communicate any such public announcement, other than by making a
timely release to the Dow Jones News Service.
 
PROCEDURES FOR TENDERING
 
     Only a registered holder of Original Notes may tender such Original Notes
in the Exchange Offer. To tender in the Exchange Offer, a holder must complete,
sign and date the Letter of Transmittal, have the signatures thereon guaranteed
if required by the Letter of Transmittal, and mail or otherwise deliver such
Letter of Transmittal to the Exchange Agent at the address set forth below prior
to 5:00 p.m., New York City time, on the Expiration Date. In addition, either
(i) certificates for such Original Notes must be received by the Exchange Agent
along with the Letter of Transmittal, or (ii) a timely confirmation of a
book-entry transfer (a "Book-Entry Confirmation") of such Original Notes, if
such procedure is available, into the Exchange Agent's account at The Depository
Trust Company (the "Book-Entry Transfer Facility") pursuant to the procedure for
book-entry transfer described below, must be received by the Exchange Agent
prior to the applicable Expiration Date, or (iii) the holder must comply with
the guaranteed delivery procedures described below. To be tendered effectively,
the Letter of Transmittal and all other required documents must be received by
the Exchange Agent at the address set forth below under "-- Exchange Agent"
prior to the applicable Expiration Date.
 
     The tender by a holder of Original Notes will constitute an 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.
 
     THE METHOD OF DELIVERY OF THE ORIGINAL NOTES AND THE APPLICABLE LETTER OF
TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE
ELECTION AND RISK OF THE HOLDER. INSTEAD OF DELIV-
 
                                       46
<PAGE>   48
 
ERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN OVERNIGHT OR HAND DELIVERY
SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO
THE EXCHANGE AGENT BEFORE THE APPLICABLE EXPIRATION DATE. NO LETTER OF
TRANSMITTAL OR ORIGINAL 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.
 
     Any beneficial owner whose Original Notes are 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 his behalf. If such beneficial owner wishes to
tender on his own behalf, such beneficial owner must, prior to completing and
executing the Letter of Transmittal and delivering his Original Notes, either
make appropriate arrangements to register ownership of the Original Notes in
such owner's name or obtain a properly completed bond power from the registered
holder. The transfer of record ownership may take considerable time.
 
     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) unless
the Original Notes tendered pursuant thereto are tendered (i) by a registered
owner who has not completed the box entitled "Special Issuance Instructions" or
"Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution. 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 participant in a recognized signature
guarantee medallion program within the meaning of Rule 17Ad-15 under the
Exchange Act (an "Eligible Institution").
 
     If a Letter of Transmittal is signed by a person other than the registered
owner of any Original Notes listed therein, such Original Notes must be endorsed
or accompanied by properly completed bond powers, signed by such registered
owner as such registered owner's name appears on the Original Notes, with
signature guaranteed by an Eligible Institution.
 
     If the Letter of Transmittal or any Original 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 evidence
satisfactory to the Company, as applicable, of their authority to so act must be
submitted with the Letter of Transmittal designated for such Original Notes.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of the tendered Original 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
Original Notes not properly tendered or any Original Notes the Company's
acceptance of which would, in the opinion of counsel for the Company, be
unlawful. The Company also reserves the absolute right to waive any defects,
irregularities or conditions of tender as to particular Original 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 Original 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 Original Notes nor shall any of them incur any
liability for failure to give such notification. Tenders of Original Notes will
not be deemed to have been made until such irregularities have been cured or
waived. Any Original 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 without cost by the Exchange Agent to the tendering
holder of such Original Notes (or, in the case of Original Notes tendered by
book-entry transfer into the Exchange Agent's account at the Book-Entry Transfer
Facility pursuant to the book-entry transfer procedures described below, such
unaccepted or non-exchanged Original Notes will be credited to an account
maintained with such Book-Entry Transfer Facility), unless otherwise provided in
the Letter of Transmittal, as soon as practicable following the Expiration Date.
 
                                       47
<PAGE>   49
 
     By tendering Original Notes in the Exchange Offer, each registered holder
will represent to the issuer of such Original Notes that, among other things,
(i) the Exchange Notes to be acquired by the holder and any beneficial owner(s)
of such Original Notes ("Beneficial Owner(s)") in connection with the Exchange
Offer are being acquired by the holder and any Beneficial Owner(s) in the
ordinary course of business of the holder and any Beneficial Owner(s), (ii) the
holder and each Beneficial Owner are not participating, do not intend to
participate, and have no arrangement or understanding with any person to
participate, in a distribution of the Exchange Notes, (iii) the holder and each
Beneficial Owner acknowledge and agree that (x) any person participating in an
Exchange Offer 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 transaction with respect to the Exchange
Notes acquired by such person and cannot rely on the position of the Staff of
the Commission set forth in no-action letters that are discussed herein under
"-- Resales of the Exchange Notes", and (y) any Participating Broker-Dealer that
receives Exchange Notes for its own account in exchange for Original Notes
pursuant to an Exchange Offer must deliver a prospectus in connection with any
resale of such Exchange Notes, but by so acknowledging, the holder shall not be
deemed to admit that, by delivering a prospectus, it is an "underwriter" within
the meaning of the Securities Act, (iv) neither the holder nor any Beneficial
Owner is an "affiliate," as defined under Rule 405 of the Securities Act, of the
Company except as otherwise disclosed to the Company in writing, and (v) the
holder and each Beneficial Owner understands that a secondary resale transaction
described in clause (iii) above should be covered by an effective registration
statement containing the selling securityholder information required by Item 507
of Regulation S-K of the Commission.
 
BOOK-ENTRY TRANSFER
 
     The Exchange Agent will make a request to establish an account with respect
to the Original Notes at the Book-Entry Transfer Facility, for purposes of the
Exchange Offer, within two business days after the date of this Prospectus, and
any financial institution that is a participant in the Book-Entry Transfer
Facility's system may make book-entry delivery of Original Notes by causing the
Book-Entry Transfer Facility to transfer such Original Notes into the Exchange
Agent's account at the Book-Entry Transfer Facility in accordance with such
Book-Entry Transfer Facility's procedures for transfer. However, although
delivery of Original Notes may be effected through book-entry transfer at the
Book-Entry Transfer Facility, the applicable Letter of Transmittal, with any
required signature guarantees and any other documents, must be transmitted to
and received by the Exchange Agent at the address set forth below under
"-- Exchange Agent" on or prior to the applicable Expiration Date or the
guaranteed delivery procedures described below must be complied with.
 
GUARANTEED DELIVERY PROCEDURES
 
     Holders who wish to tender their Original Notes and (i) whose Original
Notes are not immediately available, or (ii) who cannot deliver their Original
Notes, the Letter of Transmittal or any other required documents to the Exchange
Agent prior to the applicable Expiration Date, may effect a tender if:
 
          (a) The tender is made through an Eligible Institution;
 
          (b) Prior to the applicable 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 of the
     Original Notes, the certificate number or numbers of such Original Notes
     and the principal amount of Original Notes tendered, stating that the
     tender is being made thereby, and guaranteeing that, within five business
     days after the applicable Expiration Date, the applicable Letter of
     Transmittal (or facsimile thereof), together with the certificate(s)
     representing the Original Notes to be tendered in proper form for transfer
     and any other documents required by the applicable Letter of Transmittal,
     will be deposited by the Eligible Institution with the Exchange Agent; and
 
          (c) Such properly completed and executed Letter of Transmittal (or
     facsimile thereof), together with the certificate(s) representing all
     tendered Original Notes in proper form for transfer (or confirmation of a
     book-entry transfer into the Exchange Agent's account at DTC of Original
     Notes
 
                                       48
<PAGE>   50
 
     delivered electronically) and all other documents required by the Letter of
     Transmittal are received by the Exchange Agent within five business days
     after the applicable Expiration Date.
 
WITHDRAWAL OF TENDERS
 
     Except as otherwise provided herein, tenders of Original Notes pursuant to
an Exchange Offer, unless theretofore accepted for exchange as provided in the
Exchange Offer, may be withdrawn at any time prior to 5:00 p.m., New York City
time, on the business day prior to the Expiration Date.
 
     To be effective, a written or facsimile transmission notice of withdrawal
must be received by the Exchange Agent at its address set forth herein to 5:00
p.m., New York City time, on the business day prior to the Expiration Date. Any
such notice of withdrawal must (i) specify the name of the person having
deposited the Original Notes to be withdrawn (the "Depositor"), (ii) identify
the Original Notes to be withdrawn (including the certificate number or numbers
and aggregate principal amount of such Original Notes), and (iii) be signed by
the holder in the same manner as the original signature on the applicable Letter
of Transmittal (including any required signature guarantees). All questions as
to the validity, form and eligibility (including time of receipt) for such
withdrawal notices will be determined by the Company, whose determination shall
be final and binding on all parties.
 
     Any Original 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 Original Notes so withdrawn are validly
retendered. Properly withdrawn Original Notes may be retendered by following one
of the procedures described above under "-- Procedures for Tendering" at any
time prior to the applicable Expiration Date.
 
     Any Original Notes which have been tendered but which are not accepted for
exchange due to the rejection of the tender due to uncured defects or the prior
termination of the applicable Exchange Offer, or which have been validly
withdrawn, will be returned to the holder thereof (unless otherwise provided in
the Letter of Transmittal), as soon as practicable following the applicable
Expiration Date or, if so requested in the notice of withdrawal, promptly after
receipt by the issuer of the Original Notes of notice of withdrawal without cost
to such holder.
 
CONDITIONS OF THE EXCHANGE OFFER
 
     The Exchange Offer is subject to the condition that the Exchange Offer, or
the making of any exchange by a holder, does not violate applicable law or any
applicable interpretation of the staff of the Commission. If there has been a
change in commission policy such that in the reasonable opinion of Counsel to
the Company there is a substantial question whether the Exchange Offer is
permitted by applicable federal law, the Company has agreed to seek a no-action
letter or other favorable decision from the Commission allowing the Company to
consummate the Exchange Offer.
 
     If the Company determines in its reasonable discretion, that the Exchange
Offer is not permitted by applicable federal law, it may terminate the Exchange
Offer. In connection therewith, the Company may (i) refuse to accept any
Original Notes and return any Original Notes that have been tendered by the
holders thereof, (ii) extend the Exchange Offer and retain all Original Notes
tendered prior to the Expiration of the Exchange Offer, subject to the rights of
such holders of tendered Original Notes to withdraw their tendered Original
Notes, or (iii) waive such termination event with respect to the Exchange Offer
and accept all properly tendered Original Notes that have not been withdrawn. If
such waiver constitutes a material change in the Exchange Offer, the Company
will disclose such change by means of a supplement to this Prospectus that will
be distributed to each registered holder of Original Notes, and the Company will
extend the Exchange Offer for a period of five to ten business days, depending
upon the significance of the waiver and the manner of disclosure to the
registered holders of the Original Notes, if the Exchange Offer would otherwise
expire during such period.

FEES AND EXPENSES
 
     The expenses of soliciting tenders pursuant to the Exchange Offer will be
borne by the Company. The principal solicitation is being made by mail.
Additional solicitations may be made by officers and regular employees of the
Company and its affiliates in person, by telegraph or telephone.
 
     The Company will not make any payments to brokers, dealers or other persons
soliciting acceptances of the Exchange Offer. The Company, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
the Exchange Agent for its reasonable out-of-pocket expenses in connection
therewith. The Company may also pay brokerage houses and other custodians,
nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them
in forwarding copies of this Prospectus, Letters of Transmittal and related
documents to the beneficial owners of the Original Notes and in handling or
forwarding tenders for exchange.
 
     The expenses to be incurred in connection with the Exchange Offer,
including fees and expenses of the Exchange Agent and Trustee, accounting and
legal fees and printing costs, will be paid by the Company and are estimated to
be approximately $100,000.
 
     The tendering holder will pay all transfer taxes, if any, applicable to the
exchange of Original Notes pursuant to the Exchange Offer.
 
ACCOUNTING TREATMENT
 
     The terms of the Original Notes are not expected to be materially different
from those of the Exchange Notes. Accordingly, no gain or loss for accounting
purposes will be recognized. The expenses of the Exchange Offer will be
amortized over the term of the Exchange Notes.
 
RESALE OF THE EXCHANGE NOTES; PLAN OF DISTRIBUTION
 
     Based on no-action letters issued by the staff of the Commission to third
parties, the Company believes that the Exchange Notes issued pursuant to the
Exchange Offer in exchange for Original Notes may be offered for resale, resold
and otherwise transferred by any holder thereof (other than (i) a broker-dealer
who purchased such Original Notes directly from the Company or an "affiliate" of
the Company within the meaning of Rule 405 under the Securities Act to resell
pursuant to Rule 144A or any other available exemption under the Securities Act
or (ii) a person that is such an affiliate) without compliance with the
 
                                       50
<PAGE>   52
 
registration and prospectus delivery requirements of the Securities Act,
provided that the holder is acquiring the Exchange Notes in its ordinary course
of business and is not participating, and has no arrangement or understanding
with any person to participate, in the distribution of the Exchange Notes.
Holders of Original Notes wishing to accept the Exchange Offer must represent to
the Company that such conditions have been met. In the event that the Company's
belief is inaccurate, holders of Exchange Notes who transfer Exchange Notes in
violation of the prospectus delivery provisions of the Securities Act and
without an exemption from registration thereunder may incur liability under the
Securities Act. The Company does not assume or indemnify holders against such
liability.
 
     Each affiliate of the Company must acknowledge that such person will comply
with the registration and prospectus delivery requirements of the Securities Act
to the extent applicable. Each Participating Broker-Dealer that receives
Exchange Notes in exchange for Original Notes held for its own account, as a
result of market-making or other trading activities, must acknowledge that it
will deliver a prospectus in connection with any resale of such Exchange Notes.
Although a Participating Broker-Dealer may be an "underwriter" within the
meaning of the Securities Act, the Letter of Transmittal states that by so
acknowledging and by delivering a prospectus, such 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 such Participating Broker-Dealer in connection with
resales of Exchange Notes received in exchange for Original Notes. The Company
has agreed that, for a period of 180 days after the Expiration Date, it will
make this Prospectus and any amendment or supplement to this Prospectus
available to any such Participating Broker-Dealer for use in connection with any
such resale.

                        DESCRIPTION OF OTHER OBLIGATIONS
 
     In February 1994, the Company issued $218,500,000 of the 9 7/8% Notes. The
indenture governing the 9 7/8% Notes (the "9 7/8% Indenture") restricts, among
other things, the payment of cash dividends, repurchase of the Company's capital
stock and the making of certain other restricted payments, the incurrence of
additional indebtedness, the making of certain investments, mergers,
consolidations and sale of assets (all as defined in the 9 7/8% Indenture). Upon
certain asset sales (as defined in the 9 7/8% Indenture), the Company will be
required to offer to purchase, at 100% principal amount plus accrued interest to
the date of purchase, the 9 7/8% Notes in a principal amount equal to any net
cash proceeds (as defined in the 9 7/8% Indenture) that are not invested in
properties and assets used primarily in the same or related business to those
owned and operated by the Company at the issue date of the 9 7/8% Notes or at
the date of such asset sale and such net cash proceeds were not applied to
permanently reduce Senior Indebtedness (as defined in the 9 7/8% Indenture). The
9 7/8% Notes are redeemable at the option of the Company, in whole or in part,
at any time and from time to time, at 104.214% on March 1, 1999, declining to
100% on March 1, 2002 and thereafter. The payment of the principal of, premium,
if any, and interest on the 9 7/8% Notes is subordinated in right of payment to
the prior payment of all Senior Indebtedness (as defined in the 9 7/8%
Indenture).
 
     The Company's Canadian subsidiary Broan Limited, has a $14.7 million
secured line of credit (based on exchange rates in effect on December 31, 1996).
After giving effect to the consummation of the Offering and the Refinancing,
there will be no outstanding borrowings under this line of credit. The line of
credit contains a covenant prohibiting net aggregate dividends or other
distributions to the Company from Broan Limited in excess of $10.8 million. As
of December 31, 1996, $8.8 million in dividends or other distributions could
have been made to the Company by Broan Limited under this covenant.
 
     For additional information regarding the obligations described above, see
Note 5 of Notes to Consolidated Financial Statements of the Company included in
the Form 10-K incorporated by reference herein.
 
                       CERTAIN FEDERAL TAX CONSIDERATIONS
 
     The following is a general discussion of the material United States federal
income tax consequences of the receipt, ownership and disposition of the
Exchange Notes to United States Holders (as defined below) and Foreign Holders
(as defined below). This discussion is based on currently existing provisions of
the Internal Revenue Code of 1986, as amended (the "Code"), existing and
proposed Treasury regulations promulgated thereunder, and administrative and
judicial interpretations thereof, all as in effect or proposed on the date
hereof and all of which are subject to change, possibly with retroactive effect,
or to different interpretations. This discussion does not address the tax
consequences to subsequent purchasers of Exchange Notes and is limited to
Holders who hold the Exchange Notes as capital assets, within the meaning of
Section 1221 of the Code. This discussion also does not address the tax
consequences to nonresident aliens or foreign corporations that are subject to
United States federal income tax on a net basis on income realized with respect
to an Exchange Note because such income is effectively connected with the
conduct of a U.S. trade or business. Such Holders are generally taxed in a
similar manner to United States Holders; however, certain special rules apply.
Moreover, this discussion is for general information only and does not address
all of the tax consequences that may be relevant to particular Holders in light
of their personal circumstances or to certain types of Holders (such as certain
financial institutions, insurance companies, tax-exempt entities, dealers in
securities or persons who have hedged a risk of ownership of a Note).
 
     No ruling from the Internal Revenue Service ("IRS") will be requested with
respect to any of the matters discussed herein. There can be no assurance that
the IRS will not take a different position concerning the tax consequences of
the receipt, ownership, or disposition of the Notes, or that any such position
would be sustained. BECAUSE INDIVIDUAL CIRCUMSTANCES MAY DIFFER, EACH
PROSPECTIVE HOLDER OF EXCHANGE NOTES IS STRONGLY URGED TO CONSULT HIS OR HER OWN
TAX ADVISOR WITH RESPECT TO HIS OR HER PARTICULAR SITUATION, AND AS TO ANY
FEDERAL, FOREIGN, STATE, LOCAL OR OTHER TAX CONSIDERATIONS (INCLUDING ANY
POSSIBLE CHANGES IN TAX LAW OR INTERPRETATIONS THEREOF) AFFECTING THE RECEIPT,
HOLDING, AND DISPOSITION OF THE EXCHANGE NOTES.

TAX CONSEQUENCES TO UNITED STATES HOLDERS
 
     As used herein, the term "United States Holder" means a holder of Exchange
Notes, that is, for United States federal income tax purposes, (a) a citizen or
resident of the United States, (b) treated as a domestic corporation or domestic
partnership, or (c) an estate or trust other than a "foreign estate" or "foreign
trust" as defined in section 7701(a)(31) of the Code.
 
     Exchange of Original Notes for Exchange Notes.  The exchange by a United
States Holder of an Original Note for an Exchange Note pursuant to the Exchange
Offer will not constitute a taxable exchange of the Original Note if the
economic terms of the Exchange Note (including the interest rate) are identical
to the economic terms of the Original Note. Under the Section 1001 Regulations
relating to modifications and exchanges of debt instruments, with certain
exceptions, an alteration of a legal right or obligation that occurs by
operation of the terms of a debt instrument is not a modification of the debt
instrument and thus does not result in a taxable exchange. Therefore, even if
Liquidated Damages were payable with respect to the Original Notes but not with
respect to the Exchange Notes as a result of a Registration Default as described
under "The Exchange Offer -- Registration Rights; Liquidated Damages", the
exchange of an Original Note for an Exchange Note would not be treated as a
taxable exchange because such Liquidated Damages payments would occur pursuant
to the original terms of the Original Note. Accordingly, the Company intends to
take the position that in the circumstances described in the preceding sentence,
the exchange will not constitute a taxable exchange of the Original Notes.
 
     Interest on Exchange Notes.  Interest on the Exchange Notes generally will
be includible in the income of a United States Holder as ordinary income at the
time such interest is received or accrued, in accordance with such Holder's
method of accounting for United States federal income tax purposes. Since the
Original Notes were issued with original issue discount ("OID") that was less
than 1/4 of 1 percent of the stated redemption price at maturity, multiplied by
the number of complete years to maturity, the Original Notes qualified for the
de minimis exception from the imputed OID interest rules and, therefore, so will
the Exchange Notes.
 
     Sale, Exchange, Redemption or Retirement.  Upon the sale, exchange,
redemption, retirement or other disposition of an Exchange Note, a United States
Holder will generally recognize taxable gain or loss equal to the difference
between the amount realized on the sale, exchange, redemption or retirement and
such Holder's adjusted tax basis in the Exchange Note. A United States Holder's
adjusted tax basis in an Exchange Note generally will equal the cost of the
Original Note to such Holder. Gain or loss recognized on the disposition of an
Exchange Note generally will be capital gain or loss and will be long-term
capital gain or loss if, at the time of such disposition, the Exchange Note has
been held for more than one year.
 
     Backup Withholding.  Certain Holders of Exchange Notes may be subject to
backup withholding at the rate of 31% with respect to interest and cash received
in certain circumstances upon the disposition of such Exchange Notes. Generally,
backup withholding will be applied only if the Holder fails to furnish to the
Company its taxpayer identification number (social security or employer
identification number) in the prescribed manner, to certify that such Holder is
not subject to backup withholding, or to otherwise comply with the applicable
requirements of the backup withholding rules. Any amounts withheld under the
backup withholding rules will be allowed as a credit or refund against a United
States Holder's United States federal income tax liability, provided that such
United States Holder furnished the required information to the IRS. Certain
Holders (including, among others, corporations) are not subject to the backup
withholding requirements.
 
UNITED STATES FEDERAL TAXATION OF FOREIGN HOLDERS
 
     This section discusses special rules to a Holder of Exchange Notes that is
a Foreign Holder. For purposes of this discussion, a "Foreign Holder" means a
Holder that is not a United States Holder.
 
     Interest on Exchange Notes.  In general, interest received by any Foreign
Holder will not be subject to United States federal withholding tax, provided
that (a) such interest is effectively connected with the conduct by the Holder
of a trade or business within the United States and the Company or its paying
agent receives a properly completed Form 4224 in advance of the payments, (b)(i)
the Holder does not actually or constructively own 10% or more of the total
combined voting power of all classes of stock of the Company
 
                                       53
<PAGE>   55
 
entitled to vote, (ii) the Holder is not a "bank" within the meaning of Section
881(c)(3)(A) of the Code, (iii) the Holder is not a controlled foreign
corporation that is related to the Company actually or constructively through
stock ownership and (iv) either (x) the beneficial owner of the Note, under
penalties of perjury, provides the Company or its agent with the beneficial
owner's name and address and certifies that it is not a United States Holder on
IRS Form W-8 (or a suitable substitute form) or (y) 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") holds the Exchange Note and certifies to the Company or its agent
under penalties of perjury that such a Form W-8 (or a suitable substitute) has
been received by it from the beneficial owner of the Exchange Note or qualifying
intermediary and furnishes the payor a copy thereof or (c) the Foreign Holder is
entitled to the benefits of an income tax treaty under which the interest on the
Exchange Notes is exempt from United States withholding tax and the Foreign
Holder or such Holder's agent provides a properly executed IRS Form 1001 in the
name of the beneficial owner claiming the exemption. Payments of interest not
exempt from U.S. federal withholding tax as described above will be subject to
such withholding tax at a rate of 30% (subject to reduction under an applicable
income tax treaty). Interest payments made to a Foreign Holder that are
effectively connected with a United States trade or business conducted by such
Foreign Holder are subject to U.S. tax at the graduated rates applicable to U.S.
citizens, resident aliens and domestic corporations (an additional branch
profits tax may also apply to corporate Holders).
 
     Gain on Disposition of Exchange Notes.  A Foreign Holder generally will not
be subject to United States federal income tax or withholding tax with respect
to gain recognized on a disposition of the Exchange Notes, unless (i) in the
case of a Foreign Holder that is an individual, such Foreign Holder is present
in the United States for 183 or more days in the taxable year of the disposition
and certain other requirements are met, (ii) the Foreign Holder is an individual
who is a former citizen of the United States who lost such citizenship within
the preceding ten-year period (or former long-term permanent resident of the
United States who relinquished residency on or after February 6, 1995) whose
loss of citizenship or permanent residency had as one of its principal purposes
the avoidance of United States tax or (iii) such gain is effectively connected
with the conduct in the United States of a trade or business of the Foreign
Holder, or, if a treaty applies, the gain is attributable to a permanent
establishment in the United States (in either case, the branch profits tax also
may apply if the Foreign Holder is a corporation). If a Foreign Holder falls
under (i) above, the Holder generally will be subject to United States federal
income tax at a rate of 30% on the gain derived from the sale (or reduced treaty
rate) and may be subject to withholding in certain circumstances. If a Foreign
Holder falls within clause (ii) or (iii) above, the Holder will be taxed on the
net gain derived from the sale under the graduated United States federal income
tax rates that are applicable to U.S. citizens, resident aliens and domestic
corporations, as the case may be, and may be subject to withholding under
certain circumstances.
 
     Information Reporting and Backup Withholding.  Under current Treasury
regulations, backup withholding and information reporting on Form 1099 do not
apply to payments made by the Company or a paying agent to Foreign Holders if
the certification described under "-- Interest on Exchange Notes" is received,
provided that the payor does not have actual knowledge that the Holder is a
United States Holder. If any payments of principal and interest are made to the
beneficial owner of an Exchange Note outside the United States by or through the
foreign office of a foreign custodian, foreign nominee or other foreign agent of
such beneficial owner, or if the foreign office of a foreign "broker" (as
defined in applicable United States Treasury Department regulations) pays the
proceeds of the sale of an Exchange Note to the seller thereof, backup
withholding and information reporting will not apply. Information reporting
requirements (but not backup withholding) will apply, however, to payments by a
foreign office of a broker or custodian that is (a) a United States person, (b)
derives 50% or more of its gross income for certain periods from the conduct of
a trade or business in the United States, or (c) that is a "controlled foreign
corporation" (generally, a foreign corporation controlled by certain United
States shareholders) with respect to the United States, unless the broker or
custodian has documentary evidence in its records that the Holder is a Foreign
Holder and certain other conditions are met, or the Holder otherwise establishes
an exemption. Payment by a United States office of a broker or custodian is
subject to both backup withholding at a rate of 31% and information reporting
unless the Holder certifies under penalties of perjury that it is a Foreign
Holder, or otherwise establishes an exemption. A Foreign Holder may obtain a
refund of, or a credit against such Holder's U.S. federal income
 
                                       54

tax liability for, any amounts withheld under the backup withholding rules,
provided the required information is furnished to the IRS.
 
     Proposed Regulations.  The Internal Revenue Service released proposed
regulations on April 22, 1996 that would revise the procedures for withholding
tax on interest and the associated backup withholding and information reporting
rules described above. In particular, the regulations propose to modify the
requirements imposed on a Foreign Holder or certain intermediaries for
establishing the recipient's status as a Foreign Holder eligible for exemption
from withholding tax and backup withholding. The regulations are generally
proposed to be effective for payments of income made after December 31, 1997,
although the effective date could be extended under proposed transition rules in
particular circumstances. Foreign Holders should consult their tax advisors to
determine the effects of the potential application of the proposed regulations
to their particular circumstances.

                              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 Original Notes where such Original 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 resales. In addition, until
            , 1997, all dealers effecting transactions in the Exchange Notes may
be required to deliver a prospectus.
 
     The Company will not receive any proceeds from any sale of 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 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
commission 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 from the date of the consummation of the Exchange
Offer, 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.
 
                                 LEGAL MATTERS
 
     The legality of the Exchange Notes being offered hereby will be passed upon
for the Company by Ropes & Gray, Boston, Massachusetts.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law ("DGCL") provides that
a corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding whether civil, criminal or investigative (other than an action by or
in the right of the corporation) by reason of the fact that he is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. Section 145 further
provides that a corporation similarly may indemnify any such person serving in
any such capacity who was or is a party or is threatened to be made a party to
any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor, against expenses actually and
reasonably incurred in connection with the defense or settlement of such action
or suit if he acted in good faith and in a manner he reasonably believed to be
in or not opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Delaware Court of Chancery or such other
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.
 
     Section 102(b)(7) of the DGCL permits a corporation to include in its
certificate of incorporation a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such provision
shall not eliminate or limit the liability of a director (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL (relating to
unlawful payment of dividends and unlawful stock purchase and redemption) or
(iv) for any transaction from which the director derived an improper personal
benefit.
 
     The Company's Certificate of Incorporation provides that its Directors
shall not be liable to the Registrant or its stockholders for monetary damages
for breach of fiduciary duty as a director except to the extent that exculpation
from liabilities is not permitted under the DGCL as in effect at the time such
liability is determined. The Company's By-Laws further provides that Registrant
shall indemnify its directors and officers to the fullest extent permitted by
the DGCL.
 
     The directors and officers of the Company are covered under directors' and
officers' liability insurance policies maintained by the Company.

ITEM 22.  UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 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
of 1933 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 of controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by any 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 of whether or not
such indemnification is against public policy as expressed in the Securities Act
of 1933 and will be governed by the final adjudication of such issue.
 
     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.
 
     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.
 
     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 Section 10(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. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high and of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20 percent change in
        the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement.

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information 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 deemed
     to 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.
 
     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 (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 a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

Ladies & Gentlemen:

    Nortek, Inc., a Delaware corporation (the "COMPANY"), proposes to issue and
sell to Bear, Stearns & Co. Inc., Wasserstein Perella Securities, Inc. and BT
Securities Corporation (each, an "INITIAL PURCHASER", and collectively, the
"INITIAL PURCHASERS") $175,000,000 aggregate principal amount of its 9 1/4%
Senior Notes due 2007 (the "NOTES"), subject to the terms and conditions set
forth herein. The Notes will be issued pursuant to the provisions of an
indenture dated March 17, 1997 (the "INDENTURE"), among the Company and State
Street Bank and Trust Company, as trustee (the "TRUSTEE"). Capitalized terms
used herein and not otherwise defined shall have the meanings assigned to such
terms in the Indenture.

    The Notes will be offered and sold to the Initial Purchasers without
registration under the Securities Act of 1933, as amended (the "Act"), in
reliance on an exemption from the registration requirements of the Act. In
connection with the sale of the Notes, the Company prepared a preliminary
offering memorandum dated March 5, 1997 (including all documents incorporated
therein by reference, the "PRELIMINARY OFFERING MEMORANDUM"), and a final
offering memorandum dated March 12, 1997 (including all documents incorporated
therein by reference, the "OFFERING MEMORANDUM"), each setting forth certain
information concerning the Company and the Notes. The Company hereby confirms
that it has authorized the use of the Preliminary Offering Memorandum and the
Offering Memorandum in connection with the offer and resale of the Notes by the
Initial Purchasers. Unless stated to the contrary, all references herein to the
Offering Memorandum are to the Offering Memorandum at the date hereof (including
any supplements or amendments).


<PAGE>   3



    The Company understands that each of the Initial Purchasers proposes to make
offerings of the Notes only on the terms and in the manner set forth in the
Offering Memorandum and Sections 2 and 3 hereof, as soon as each such Initial
Purchaser deems advisable after this Agreement has been executed and delivered,
(i) to persons in the United States whom such Initial Purchaser reasonably
believes to be qualified institutional buyers ("QIBs") as defined in Rule 144A
under the Act, as such rule may be amended from time to time ("RULE 144A"), in
transactions meeting the requirements of Rule 144A, and/or (ii) to a limited
number of other institutional "Accredited investors" ("ACCREDITED INVESTORS") as
defined in Rule 501(a)(1), (2), (3) or (7) under Regulation D of the Act, in
private sales exempt from registration under the Act.

    1. ISSUANCE OF SECURITIES. The Company proposes, upon the terms and subject
to the conditions set forth herein, to issue and sell to the Initial Purchasers
an aggregate of $175,000,000 principal amount of Notes. The Notes and the Series
B Notes (as defined below) issuable in exchange therefor are collectively
referred to herein as the "NOTES".

    Upon original issuance thereof, and until such time as the same is no longer
required under the applicable requirements of the Act, the Notes (and all
securities issued in exchange therefor or in substitution thereof) shall bear
the following legend:

     THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
     AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR
     SOLD TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY PERSON EXCEPT AS SET FORTH
     IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1)
     REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN
     RULE 144A UNDER THE SECURITIES ACT), (B) IT IS AN "ACCREDITED INVESTOR" (AS
     DEFINED IN RULE 501(a)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT) WHO IS
     AN INSTITUTION (AN "INSTITUTIONAL ACCREDITED INVESTOR"), OR (C) IT IS NOT A
     U.S. PERSON AND IS ACQUIRING THIS NOTE IN AN OFFSHORE TRANSACTION IN
     COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (2) AGREES THAT IT WILL
     NOT PRIOR TO THE DATE WHICH IS TWO YEARS AFTER THE LATER OF THE DATE OF
     ORIGINAL ISSUANCE OF THIS NOTE AND THE LAST DATE ON WHICH THE COMPANY OR
     ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF THIS NOTE (THE "RESALE
     RESTRICTION TERMINATION DATE") OFFER, SELL OR OTHERWISE TRANSFER THIS NOTE,
     EXCEPT (A) TO THE COMPANY,(B) TO A PERSON WHOM THE SELLER REASONABLY
     BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER PURCHASING FOR ITS OWN ACCOUNT
     OR FOR THE ACCOUNT OF ANOTHER QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE
     WITH THE RESALE PROVISIONS OF RULE 144A UNDER THE SECURITIES ACT, (c) TO
     AN INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER,
     FURNISHES TO THE TRUSTEE A WRITTEN CERTIFICATION CONTAINING CERTAIN
     REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF
     THIS NOTE (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE TRUSTEE), (D)
     PURSUANT TO THE RESALE LIMITATIONS PROVIDED BY



                                       2

<PAGE>   4



     RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), (E) PURSUANT TO AN
     EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, (F) OUTSIDE THE
     UNITED STATES TO A FOREIGN PERSON IN A TRANSACTION MEETING THE REQUIREMENTS
     OF REGULATION S UNDER THE SECURITIES ACT OR (G) PURSUANT TO ANY OTHER
     AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES
     ACT (BASED UPON AN OPINION OF COUNSEL REASONABLY ACCEPTABLE TO THE COMPANY
     IF THE COMPANY SO REQUESTS), SUBJECT IN EACH OF THE FOREGOING CASES TO ANY
     REQUIREMENT OF LAW THAT THE DISPOSITION OF ITS PROPERTY OR THE PROPERTY OF
     SUCH ACCOUNT BE AT ALL TIMES WITHIN ITS CONTROL AND TO COMPLIANCE WITH
     APPLICABLE STATE SECURITIES LAWS AND (3) AGREES THAT IT WILL DELIVER TO
     EACH PERSON TO WHOM THIS NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE
     EFFECT OF THIS LEGEND. IF THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL
     ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO
     THE TRUSTEE AND THE COMPANY SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER
     INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH
     TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION
     NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THE
     FOREGOING RESTRICTIONS ON RESALE WILL NOT APPLY SUBSEQUENT TO THE RESALE
     RESTRICTION TERMINATION DATE.

     2. OFFERING. The Notes will be offered and sold to the Initial Purchasers
pursuant to an exemption from the registration requirements under the Act.

    Each of the Initial Purchasers has advised the Company that it proposes to
offer the Notes for resale (the "EXEMPT RESALES") on the terms and conditions
set forth in this Agreement and in the Offering Memorandum, as amended or
supplemented, solely to (i) persons whom such Initial Purchaser reasonably
believes to be QIBs, and (ii) a limited[ number of other institutional investors
whom such Initial Purchaser reasonably believes to be Accredited Investors that
are purchasing for their own accounts or for the account of an Accredited
Investor, for investment purposes only and not with a view to, or for offer or
sale in connection with, any distribution of the Notes in violation of the Act;
PROVIDED, HOWEVER, that with respect to clause (ii) each such Accredited
Investor shall be required to complete and deliver a purchaser letter,
substantially in the form of Annex A to the Offering Memorandum, to such Initial
Purchaser prior to the confirmation of any order. The Initial Purchasers will
offer the Notes to such Eligible Purchasers initially at a price equal to 100 %
of the principal amount thereof. Such price may be changed at any time without
notice.

    The Initial Purchasers and other holders (including subsequent transferees)
of the Notes will have the registration rights set forth in a registration
rights agreement relating thereto (the "REGISTRATION RIGHTS AGREEMENT"), to be
dated the Closing Date and substantially in the form of EXHIBIT B hereto, for so
long as such Notes constitute "REGISTRABLE SECURITIES" (as defined in the
Registration Rights Agreement). Pursuant to the Registration Rights Agreement,
the Company will agree to file with the Securities and Exchange Commission (the
"COMMISSION"), under the circumstances set forth therein, (i) a registration



                                       3

<PAGE>   5



statement under the Act (the "EXCHANGE OFFER REGISTRATION STATEMENT") relating
to the 9 1/4% Senior Notes due 2007 (the "SERIES B NOTES") to be offered in
exchange for the Notes (the "EXCHANGE OFFER") and (ii) a shelf registration
statement pursuant to Rule 415 under the Act (the "SHELF REGISTRATION
STATEMENT") relating to resales by certain holders of the Notes, and, if
applicable, the Private Exchange Notes (as defined in the Registration Rights
Agreement) and to use its best efforts to cause such Registration Statements to
be declared effective and to consummate the Exchange Offer. This Agreement, the
Notes, the Series B Notes, the Private Exchange Notes, the Indenture and the
Registration Rights Agreement are hereinafter sometimes referred to collectively
as the "OPERATIVE DOCUMENTS."

    3. PURCHASE, SALE AND DELIVERY. (a) On the basis of the representations,
warranties and covenants contained in this Agreement, and subject to the terms
and conditions set forth herein, the Company agrees to issue and sell to the
Initial Purchasers, and the Initial Purchasers agree to purchase from the
Company, $175,000,000 aggregate principal amount of Notes. The purchase price
for the Notes will be $967.97 per $1,000 principal amount of Notes.

    (b) Delivery of the Notes shall be made, against payment of the purchase
price therefor, at the offices of Paul, Hastings, Janofsky & Walker LLP, 399
Park Avenue, New York, New York 10022 on Monday, March 17, 1997, at 10:00 a.m.,
New York City time, or such other location, date and time as the Initial
Purchasers and the Company shall agree (such date and time of delivery and
payment, the "CLOSING DATE").

    (c) One or more of the Notes in definitive form, registered in the name of
Cede & Co., as nominee of The Depository Trust Company ("DTC"), having an
aggregate amount corresponding to the aggregate amount of the Notes sold
pursuant to Exempt Resales to QIBs and Accredited Investors (the "GLOBAL NOTE")
shall be delivered by the Company to the Initial Purchasers (or as the Initial
Purchasers direct), against payment by the Initial Purchasers of the purchase
price therefor, by wire transfer of same day funds, to an account designated by
the Company, provided that the Company shall give at least two business days'
prior written notice to the Initial Purchasers of the information required to
effect such wire transfer. The Global Note shall be made available to the
Initial Purchasers for inspection not later than 9:00 a.m., New York City time,
on the business day immediately preceding the Closing Date.

     4. COVENANTS OF THE COMPANY. The Company covenants and agrees with each of
the Initial Purchasers as follows:

          (a) To advise the Initial Purchasers promptly and, if requested by the
     Initial Purchasers, confirm such advice in writing, (i) of the issuance by
     any state securities commission of any stop order suspending the
     qualification or exemption from qualification of any Notes-for offering or
     sale in any jurisdiction, or the initiation of any proceeding for such
     purpose by any state securities commission or other regulatory authority
     and (ii) of the occurrence of any event that makes any statement of a
     material fact made in the Offering Memorandum untrue or that requires the
     making of any additions to or changes in the Offering Memorandum in order
     to make the statements therein, in the light of the circumstances under
     which they are made, not misleading. The Company shall use its best efforts
     to prevent the issuance of any stop order or order suspending the
     qualification or exemption of any Notes under any state securities or Blue
     Sky laws and, if any such order is issued, to obtain the withdrawal or
     lifting of such order at the earliest possible time.


                                       4
<PAGE>   6



          (b) The Company will furnish to the Initial Purchasers, counsel for
     the Initial Purchasers and those persons identified by the Initial
     Purchasers to the Company, without charge, as many copies of the
     Preliminary Offering Memorandum and the Offering Memorandum, and any
     amendments or supplements thereto, as the Initial Purchasers and counsel
     for the Initial Purchasers may reasonably request. The Company consents to
     the use of the Preliminary Offering Memorandum and the Offering Memorandum,
     and any amendments and supplements thereto by the Initial Purchasers in
     connection with Exempt Resales.

          (c) Before amending or supplementing the Preliminary Offering
     Memorandum or the Offering Memorandum, to furnish to the Initial Purchasers
     a copy of each such proposed amendment or supplement and not to make any
     such proposed amendment or supplement to which the Initial Purchasers
     reasonably object. The Company shall promptly prepare, upon the reasonable
     request of the Initial Purchasers, any amendment or supplement to the
     Preliminary Offering Memorandum or the Offering Memorandum that may be
     necessary or advisable in connection with Exempt Resales.

          (d) If, after the date hereof and prior to completion of any Exempt
     Resale by the Initial Purchasers to purchasers who are not affiliated with
     the Initial Purchasers, any event shall occur or condition shall exist as a
     result of which, in the judgment of the Company or counsel for the Company
     or counsel for the Initial Purchasers, it becomes necessary or advisable to
     amend or supplement the Preliminary Offering Memorandum or Offering
     Memorandum so that it does not include 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 existing at the time
     such Preliminary Offering Memorandum or Offering Memorandum is delivered to
     a purchaser, not misleading, or if in the opinion of the Company or counsel
     for the Company or counsel to the Initial Purchasers it is necessary or
     advisable to amend or supplement the Preliminary Offering Memorandum or
     Offering Memorandum to comply with applicable law, the Company will (i)
     notify the Initial Purchasers, in writing, to suspend use of the
     Preliminary Offering Memorandum or Offering Memorandum as promptly as
     practicable, and (ii) promptly prepare, at its own expense, an appropriate
     amendment or supplement to such Preliminary Offering Memorandum or Offering
     Memorandum in accordance with Section 5(c) above, so that the statements
     therein as so amended or supplemented will not include 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 existing at
     the time it is so delivered to a purchaser, not misleading, or so that such
     Preliminary Offering Memorandum or Offering Memorandum will comply with
     applicable law.

          (e) To cooperate with the Initial Purchasers and counsel for the
     Initial Purchasers in connection with the qualification or registration of
     the Notes for the offering and sale under the securities or Blue Sky laws
     of such states and other jurisdictions as the Initial Purchasers may
     reasonably request and to continue such qualification in effect so long as
     required for the Exempt Resales; PROVIDED, HOWEVER, that the Company shall
     not be required in connection therewith to register or qualify as a foreign
     corporation where it is not now so qualified or to take any action that
     would subject it to service of process in suits or taxation, in each case,
     other than as to matters and transactions relating to the Preliminary
     Offering Memorandum, the Offering Memorandum or Exempt Resales, in any
     jurisdiction where it is not now so subject. The Company shall promptly
     advise the Initial Purchasers of the receipt of any notification with



                                       5
<PAGE>   7



     respect to the suspension of the qualification or exemption from
     qualification of the Notes for offering or sale in any jurisdiction or the
     institution, or to the Company's knowledge the threat or contemplation of
     any proceeding for such purpose.

          (f) Whether or not the transactions contemplated by this Agreement are
     consummated or this Agreement becomes effective or is terminated, the
     Company will pay all costs, expenses, fees and taxes incident to the
     performance of the obligations of the Company hereunder, including in
     connection with: (i)the preparation, printing, filing and distribution of
     the Preliminary Offering Memorandum and the Offering Memorandum (including,
     without limitation, financial statements) and all amendments and
     supplements thereto required pursuant hereto, (ii)the issuance, transfer
     and delivery by the Company of the Notes to the Initial Purchasers, (iii)
     the qualification or registration of the Notes for offer and sale under the
     securities or Blue Sky laws of the several states (including, without
     limitation, the cost of preparing, printing and mailing a preliminary and
     final Blue Sky Memorandum and the reasonable fees and disbursements of
     counsel for the Initial Purchasers relating thereto) and the expenses
     related to all other agreements, memoranda, correspondence and all other
     documents prepared and delivered in connection herewith and with the Exempt
     Resales, (v) furnishing such copies of the Preliminary Offering Memorandum
     and the Offering Memorandum, and all amendments and supplements thereto, as
     may be requested for use in connection with Exempt Resales, (vi) the
     preparation of certificates for the Notes (including, without limitation,
     printing and engraving thereof), (vii) the fees, disbursements and expenses
     of the Company's counsel and accountants, (viii) all expenses and listing
     fees in connection with the application for quotation of the Notes in the
     Private Offerings, Resales and Trading Through Automated Linkages
     ("PORTAL") market of the National Association of Securities Dealers, Inc.
     ("NASD"), (ix) all fees and expenses (including fees and expenses of
     counsel) of the Company in connection with the approval of the Notes by DTC
     for "book-entry" transfer, (x) rating the Notes by rating agencies, (xi)
     the fees and expenses of the Trustee and its counsel, (xii) the performance
     by the Company of its other obligations under this Agreement and the other
     Operative Documents, and (xiii) "roadshow" travel and other expenses
     incurred in connection with the marketing and sale of the Notes. Except as
     provided in this Section 4(f) and Sections 6, 7 and 11(d) hereof, the
     Initial Purchasers shall pay all of their own costs and expenses, including
     the fees of counsel for the Initial Purchasers.

          (g) The Company will use the proceeds from the sale of the Notes in
     the manner specified in the Offering Memorandum under the caption "Use of
     Proceeds."

          (h) The Company will not voluntarily claim, and will resist actively
     any attempts to claim, the benefit of any usury laws against the holders of
     any Notes.

          (i) None of the Company, its subsidiaries or affiliates (as defined
     in Rule 501(b) under the Act) will sell, offer for sale or solicit offers
     to buy or otherwise negotiate in respect of any security (as defined in the
     Act) that could be integrated with the sale of the Notes in a manner that
     would require the registration of the Notes under the Act or take any other
     action that would result in the Exempt Resales not being exempt from
     registration under the Act.

          (j) The Company will for so long as any of the Notes remain

     5.   Representations and Warranties.
          ------------------------------

          (a) The Company represents and warrants to, and agrees with, the
Initial Purchasers that:

          (i) The Preliminary Offering Memorandum did not as of its date, and
     the Offering Memorandum does not, and any supplement or amendment to the
     Offering Memorandum will not, contain an untrue statement of a material
     fact or omit to state any material fact required to be stated therein or
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading. No representation
     and warranty is made in this subsection (i), however, with respect to any
     information contained in or omitted from the Preliminary Offering
     Memorandum or the Offering Memorandum or any amendment thereof or
     supplement thereto in reliance upon and in conformity with information
     furnished in writing to the Company by any Initial Purchaser relating to
     such Initial Purchaser expressly for use in connection with the preparation
     thereof.

          (ii) No stop order preventing or suspending the use of the Preliminary
     Offering Memorandum or the Offering Memorandum, or any amendment or
     supplement thereto, or any order asserting that any of the transactions
     contemplated by this Agreement are subject to the registration requirements
     of the Act, has been issued, nor, to the best knowledge of the Company, is
     threatened.

          (iii) Arthur Andersen LLP, which has certified the financial
     statements and supporting schedules included in the Offering Memorandum, is
     an independent certified public accounting firm with regard to the Company
     and its subsidiaries as required by the Act if the Offering were required
     to be registered under the Act.

          (iv) Subsequent to the respective dates as of which information is
     given in the Offering Memorandum, except as set forth in the Offering
     Memorandum, there has been no material adverse change, or any fact known to
     the Company which could reasonably be expected to result in a material
     adverse change, in the business, prospects, properties, assets, liabilities
     (contingent or otherwise) earnings, operations, condition (financial or
     otherwise) or results of operations of the Company and its subsidiaries
     taken as a whole, whether or not arising from transactions in the ordinary
     course of business or any loss of, or damage to, properties (whether or not
     insured) which could reasonably be expected to affect materially and
     adversely the business, prospects, properties, assets, liabilities
     (contingent or otherwise), earnings, operations, condition (financial or
     otherwise) or results of operations of the Company and its subsidiaries
     taken as a whole. Since the date of the latest balance sheet presented in
     the Offering Memorandum, except as expressly disclosed in the Offering
     Memorandum or in any reports filed by the Company with the Commission
     pursuant to the Exchange Act or in accordance with any plan contained in
     any such report, neither the Company nor any of its subsidiaries has (i)
     incurred or undertaken any liabilities or obligations, direct or
     contingent, that are material to the Company and its subsidiaries taken as
     a whole, (ii) entered into any material transaction not in the ordinary
     course of business and consistent with past practice or (iii) declared or
     paid any dividend or made any distribution on any shares of its capital
     stock or redeemed, purchased or otherwise acquired or agreed to redeem,
     purchase or otherwise acquire any shares of its capital stock.

          (v) The Company has the requisite corporate power and the authority to
     enter into this Agreement and each of the other Operative Documents to
     which it is a party, perform each of its obligations hereunder and
     thereunder and to consummate the transactions contemplated hereby and
     thereby including without limitation to issue, sell and deliver the Notes
     to be sold by it hereunder. This Agreement and the transactions
     contemplated herein have been duly and validly authorized by the Company
     and this Agreement has been duly and validly executed and delivered by the
     Company and is a valid and binding obligation of the Company, enforceable
     against the Company in accordance with its terms, except (i) as the
     enforceability thereof may be limited by bankruptcy, insolvency, fraudulent
     conveyance, reorganization, moratorium or other similar laws affecting the
     enforcement of creditors rights generally and by general equitable
     principles and (ii) to the extent that rights to indemnity and contribution
     hereunder may be limited by federal or state securities laws or the public
     policy underlying such laws.

          (vi) The execution, delivery and performance of this Agreement and
     each of the other Operative Documents by the Company and the consummation
     by the Company of the transactions contemplated hereby and thereby
     (including the issuance, sale and delivery of the Notes by the Company) do
     not and will not (a) conflict with or result in a breach of any of the
     terms and provisions of, or constitute a default (or an event which with
     notice or lapse of time, or both, would constitute a default), give rise to
     any right to accelerate the maturity or require the prepayment of any
     obligation of the Company or any of its subsidiaries or require any
     consent, or result in the creation or imposition of any lien, charge or
     encumbrance upon any property or assets of the Company or its subsidiaries,
     pursuant to the terms of any contract, lease, indenture, mortgage, deed of
     trust, loan agreement, instrument, franchise, license, permit or other
     agreement or document to which the Company or any of its subsidiaries is a
     party or by which the Company or any of its subsidiaries or their
     respective properties or assets may be bound, except for such conflicts,
     breaches, defaults, liens, charges or encumbrances which would not
     individually or in the aggregate have a material adverse effect on the
     Company and its subsidiaries taken as a whole or prohibit or restrict the
     consummation of the transactions contemplated hereby and thereby; (b)
     violate or conflict with any provision of the certificate of incorporation
     or by-laws (or equivalent instruments) of the Company or any of its
     subsidiaries; or (c) violate or conflict with any judgment, decree, order,
     statute, rule or regulation of any court or any public, governmental or
     regulatory agency or body having jurisdiction over the Company or any of
     its subsidiaries or any of their respective properties or assets except for
     such violations or conflicts which would not individually or in the
     aggregate have a material adverse effect on the Company and its
     subsidiaries taken as a whole or prohibit or restrict the consummation of
     the transactions contemplated hereby and thereby.

          (vii) No consent, approval, authorization, order, registration,
     filing, qualification, license or permit of or with any court or any
     public, governmental or regulatory agency or body having jurisdiction over
     the Company or any of its subsidiaries or any of their respective
     properties or assets is required for the valid execution, delivery and
     performance of this Agreement or any of the other Operative Documents and
     the consummation by the Company of the transactions contemplated hereby and
     thereby, including the issuance, sale and delivery of the Notes to be
     issued, sold and delivered by the Company hereunder except such as have
     been obtained and made (or, in the case of the Registration Rights
     Agreement, will be obtained or


                                       9

     made) under the Act, the Trust Indenture Act of 1939, as amended (the
     "TRUST INDENTURE ACT"), and state securities or Blue Sky laws and
     regulations or such as may be required by the NASD.

          (viii) All of the outstanding shares of capital stock of the Company
     are duly and validly authorized and issued, fully paid and nonassessable,
     were issued in compliance with all applicable federal and state securities
     laws and were not issued in violation of any preemptive rights nor do any
     such shares of capital stock have the benefit of any preemptive rights. The
     Company had, at December 31, 1996, a duly authorized and outstanding
     capitalization as set forth under the caption "Capitalization" in the
     Offering Memorandum. On December 31, 1996, after giving pro forma effect to
     the issuance and sale of the Notes pursuant hereto and the other
     transactions referred to in the Offering Memorandum, the Company would have
     had an authorized and outstanding capitalization as set forth in the
     Offering Memorandum in the "As Adjusted" column under the caption
     "Capitalization". No holder of any securities of the Company is entitled to
     have such securities (other than the Notes, the Exchange Notes and the
     Private Exchange Notes, if any) registered under any registration rights or
     similar agreement.

          (ix) The Company and each of its subsidiaries has been duly organized
     and is validly existing as a corporation in good standing under the laws of
     its jurisdiction of incorporation. The Company and each of its subsidiaries
     is duly qualified and in good standing as a foreign corporation in each
     jurisdiction in which the character or location of its properties (owned,
     leased or licensed) or the nature or conduct of its business makes such
     qualification necessary, except for those failures to be so qualified or in
     good standing which could not, individually or the aggregate, have a
     material adverse effect on the business, prospects, properties, assets,
     liabilities (contingent or otherwise), earnings, operations, condition
     (financial or otherwise) or results of operations of the Company and its
     subsidiaries taken as a whole, and neither the Company nor any of its
     subsidiaries has received any claim or notice from any official in any
     jurisdiction that it is required to be qualified or licensed to do business
     in any jurisdiction in which it is not so qualified or licensed. The
     Company and each of its subsidiaries has all requisite power and authority,
     and all necessary consents, approvals, authorizations, orders,
     registrations, qualifications, licenses and permits of and from all public,
     regulatory or governmental agencies and bodies, to own, lease and operate
     its properties and conduct its business as now being conducted and as
     described in the Offering Memorandum except for consents, approvals,
     authorizations, orders, registrations, qualifications, licenses and permits
     the failure to obtain which, individually or in the aggregate, would not
     reasonably be expected to have a material adverse effect on the business,
     prospects, properties, assets, liabilities (contingent or otherwise),
     earnings, operations, condition (financial or otherwise) or results of
     operations of the Company and its subsidiaries, and the Company has not
     received any notice of any proceedings relating to the revocation or
     modification of any thereof, nor is the Company aware of any basis
     therefor, and no such consent, approval, authorization, order,
     registration, qualification, franchise, license or permit contains a
     materially burdensome restriction that is not adequately and accurately
     disclosed in the Offering Memorandum.

          (x) As of December 31, 1996 and as of the date hereof, all of the
     outstanding shares of capital stock of each Significant Subsidiary (as
     defined in Rule 1-02 of Regulation S-X promulgated by the Commission) of
     the Company have been duly and validly issued, are fully paid and
     non-assessable and were not issued in violation of preemptive rights,
     repurchase rights



                                       10

<PAGE>   12



     or rights of first refusal and are owned directly or indirectly by the
     Company, free and clear of any lien, pledge, encumbrance, claim, security
     interest, restriction on transfer, stockholders' agreement, voting trust or
     other defect of title whatsoever. The Company owns no controlling interest
     in any other corporation, partnership or other entity and does not directly
     or indirectly own any shares of stock or any other securities of any
     corporation or have any equity interest in any firm, partnership,
     association or other entity, other than (a) minority investments in
     marketable securities that may be made in the ordinary course of business
     as a part of its investment of excess cash assets and (b) a 40% interest
     held by the Company in Spalding Composites, Inc.

          (xi) Except as described in the Offering Memorandum there is no
     action, suit, investigation or proceeding, governmental or otherwise, to
     which the Company or any of its subsidiaries is a party or to which any
     property of the Company or any of its subsidiaries is subject or which is
     pending or, to the best knowledge of the Company, threatened against the
     Company or any of its subsidiaries which (i) could reasonably be expected
     to have a material adverse effect on the Company or its business,
     prospects, properties, assets, liabilities (contingent or otherwise),
     earnings, operations, condition (financial or otherwise) or results of
     operations or (ii) seeks to restrain, enjoin, prevent the consummation of,
     or otherwise challenge the issuance of, the Notes or the execution and
     delivery of this Agreement or any of the other transactions contemplated
     hereby, or questions the legality or validity of any such transactions or
     that seeks to recover damages or obtain other relief in connection with any
     of such transactions.

          (xii) Except as provided for in this Agreement, the Company has not
     taken and will not take, directly or indirectly, any action designed to
     cause or result in, or which constitutes or which might reasonably be
     expected to constitute, the stabilization or manipulation of the price of
     any security of the Company in order to facilitate the sale or resale of
     the Notes or since the date of the Preliminary Offering Memorandum (A)
     sold, bid for, purchased or paid any person any compensation for soliciting
     purchases of the Notes (other than the Initial Purchasers) or (B) paid or
     agreed to pay to any person any compensation for soliciting another to
     purchase any other securities of the Company.

          (xiii) The consolidated financial statements, including the notes
     thereto, and supporting schedules included in the Offering Memorandum
     comply as to form in all material respects with the requirements applicable
     to a Report on Form 10-K under the Exchange Act and present fairly the
     financial condition, results of operations, stockholders' investment and
     cash flows and other information purported to be shown therein of the
     Company and its subsidiaries at the dates and for the periods indicated'
     and the supporting schedules included in the Offering Memorandum present
     fairly the information required to be stated therein. Except as disclosed
     in such financial statements, such consolidated financial statements have
     been prepared in accordance with generally accepted accounting principles
     consistently applied throughout the periods involved, and are in accordance
     with the books and records of the Company and its subsidiaries in all
     material respects. No other financial statements are required to be
     included in the Offering Memorandum. The financial data set forth in the
     Offering Memorandum under the captions "Summary Consolidated Financial
     Information", "Capitalization", "Selected Consolidated Financial
     Information" and "Management's Discussion and Analysis of Financial
     Condition and Results of Operations" fairly present, on the basis stated in
     the Offering Memorandum, the information set



                                       11


<PAGE>   13



     forth therein and have been compiled on a basis consistent with that of the
     audited financial statements included in the Offering Memorandum. All other
     financial information and statistical data set forth in the Offering
     Memorandum are, in all material respects, accurately presented and have
     been prepared on an accounting basis consistent with the financial
     statements included in the Offering Memorandum. The "as adjusted" financial
     information included in the Offering Memorandum that gives effect to the
     issuance of the Notes, the application of the net proceeds therefrom and
     the other transactions and events specified therein has been properly
     compiled on the basis of the assumptions set forth with respect thereto.

          (xiv) Each of the Company and its subsidiaries has good and marketable
     title to all the properties and assets reflected as owned in the financial
     statements (or elsewhere) in the Offering Memorandum, subject to no lien,
     mortgage, pledge, charge or encumbrance of any kind except (i) those, if
     any, reflected in the financial statements, or (ii) those which are not
     material in amount and do not adversely affect the use made and proposed to
     be made of such property by the Company and its subsidiaries (except for
     such uses the failure of which to be made would not reasonably be expected
     to have a material adverse effect on the business, prospects, properties,
     assets, liabilities (contingent or otherwise), earnings, operations,
     condition (financial or otherwise) or results of operations of the Company
     or its subsidiaries. Each of the Company and its subsidiaries holds its
     leased properties under valid, subsisting and enforceable leases, with such
     exceptions as are not, individually or in the aggregate, material and do
     not, individually or in the aggregate, interfere with the use made or
     proposed to be made of such properties by the Company or any of its
     subsidiaries (except for such uses the failure of which to be made would
     not reasonably be expected to have a material adverse effect on the
     business, prospects, properties, assets, liabilities (contingent or
     otherwise), earnings, operations, condition (financial or otherwise) or
     results of operations of the Company or its subsidiaries. Except as
     disclosed in the Offering Memorandum, the Company and each of its
     subsidiaries owns or leases all such properties as are necessary to its
     operations as now conducted or as proposed to be conducted (except for such
     properties the failure to own or lease which would not reasonably be
     expected to have a material adverse effect on the business, prospects,
     properties, assets, liabilities (contingent or otherwise), earnings,
     operations, condition (financial or otherwise) or results of operations of
     the Company and its subsidiaries.

          (xv) The Company is not, and upon consummation of the transactions
     contemplated hereby will not be, subject to registration as an "investment
     company" or an entity "controlled by" an "investment company" within the
     meaning of Investment Company Act of 1940 and the rules and regulations
     promulgated thereunder; the Company will conduct its business and financial
     affairs in such a manner as to ensure that it will not become an
     "investment company" or an entity "controlled" by an "investment company".

          (xvi) The Company and each of its subsidiaries have (i) filed all
     federal, state and local and foreign tax returns which are required to be
     filed through the date hereof, and all such tax returns are true, complete
     and accurate in all material respects, or (ii) received valid extensions
     thereof and have paid all taxes shown on such returns and all assessments
     received by them except where, in the case of state and local and foreign
     tax returns, the failure to file in clause (i), or extend the due date of
     or pay the same in clause (ii), in the aggregate, could not reasonably be
     expected to have a material adverse effect on the business, prospects,
     properties,



                                       12

<PAGE>   14


     assets, liabilities (contingent or otherwise), earnings, operations,
     condition (financial or otherwise) or results of operations of the Company
     and its subsidiaries' the Company has no knowledge of any tax deficiency
     which has been or might be asserted against the Company or any of its
     subsidiaries which could materially and adversely affect the business or
     properties of the Company and its subsidiaries taken as a whole; to the
     Company's best knowledge, all tax liabilities are adequately provided for
     on the consolidated books of the Company.

          (xvii) The Company and each of its subsidiaries own or possess
     adequate licenses or other rights to use all patents, trademarks, service
     marks, trade names, copyrights, technology and know-how necessary to
     conduct the business now or proposed to be conducted by the Company and
     each of its subsidiaries as described in the Offering Memorandum except for
     those patents, trademarks, service marks, trade names, copyrights,
     technology and know-how the failure to own or have the right to use would
     not have a material adverse effect on the Company and its subsidiaries
     taken as a whole, and, except as disclosed in the Offering Memorandum,
     neither the Company nor any of its subsidiaries has received any notice of
     infringement of or conflict with (or knows of such infringement of or
     conflict with) rights of others with respect to any patents, trademarks,
     service marks, trade names, copyrights or know-how except for conflicts
     which would not reasonably be expected to have a material adverse effect on
     the business, prospects, properties, assets, liabilities (contingent or
     otherwise), earnings, operations, condition (financial or otherwise) or
     results of operations of the Company and its subsidiaries; and to the best
     knowledge of the Company, the Company and each of its subsidiaries do not
     in the conduct of their business as now conducted or proposed to be
     conducted, infringe or conflict with any such rights of any third party.

          (xviii) There are no contracts, indentures, mortgages, loan
     agreements, notes, leases or other agreements or instruments or other
     documents (collectively, "DOCUMENTS") required to be described or referred
     to in the Offering Memorandum other than those described or referred to
     therein or in the Form 10-K of the Company for the year ended December 31,
     1996 included as Annex B attached thereto and incorporated therein by
     reference; all such descriptions are accurate in all material respects and
     present fairly the information described therein. All such Documents to
     which the Company is a party have been duly authorized, executed and
     delivered by the Company, constitute valid and binding agreements of the
     Company and are enforceable against the Company in accordance with the
     terms thereof, except as the enforceability thereof may be limited by
     bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium
     or other similar laws affecting the enforcement of creditors' rights
     generally and by general equitable principles.

          (xix) There are no outstanding loans, advances (except normal 
     advances for business expenses in the ordinary course of business), or

     of its subsidiaries or any of the members of the families of any of them,
     except as adequately disclosed in the Offering Memorandum; all such

     information required to be described in, or incorporated by reference in, a
     Registration Statement on Form S-3.

          (xx) Each of the Company and its subsidiaries maintains a system of
     internal accounting controls sufficient to provide reasonable assurances
     that (A) transactions are executed in accordance with management's general
     or specific authorizations; (B) transactions are recorded as necessary to
     permit preparation of financial statements in conformity with generally
     accepted accounting principles and to maintain accountability for assets;
     (C) access to assets is permitted only in accordance with management's
     general or specific authorization; and (D) the recorded accountability for
     assets is compared with existing assets at reasonable intervals and
     appropriate action is taken with respect to any differences.

          (xxi) Neither the Company nor any of its subsidiaries is in violation
     or breach of, or in default (nor has any event occurred which with notice,
     or lapse of time, or both, would constitute a default) of any contract,
     agreement, indenture, loan or other agreement, instrument, mortgage, note,
     permit, lease, license, arrangement or understanding to which the Company
     or any of its subsidiaries is a party or by which the Company, any of its
     subsidiaries or any of their respective properties may be bound where such
     default, either individually or together with all such other defaults,
     could reasonably be expected to have a material adverse effect on the

     business, prospects, properties, assets, liabilities (contingent or
     otherwise), earnings, operations, condition (financial or otherwise) or
     results of operations of the Company and its subsidiaries. Each of the

     liabilities (contingent or otherwise), earnings, operations, condition
     (financial or otherwise) or results of operations of the Company and its
     subsidiaries. Neither the Company nor any of its subsidiaries is in

     otherwise) or results of operations of the Company.

          (xxii) Except as described in the Offering Memorandum, (i) no labor
     dispute with the employees of the Company and any of its subsidiaries
     exists or, to the best knowledge of the Company, is threatened and (ii) the
     Company is not aware of any labor disturbance by the employees of any of

     material adverse effect on the

     person or entity or to require the Company to include such securities in
     the securities to be registered in the Exchange Offer.

          (xxiv) To the best knowledge of the Company, except as disclosed in
     the Offering Memorandum, neither the Company nor any of its subsidiaries is

     with all terms and conditions of any such permits, licenses or approvals,
     except any such violation of law or regulation, failure to receive required
     permits, licenses or other approvals or failure to comply with the terms
     and conditions of such permits, licenses or approvals which could not,
     individually or together' with all such other violations or failures, have
     a material adverse effect on the Company or its business, prospects,
     properties, assets, liabilities (contingent or otherwise), earnings,
     operations, condition (financial or otherwise) or results of operations.

          (xxv) Neither the Company nor, to its knowledge, any director,

          (xxviii) The Company has complied and will comply with all provisions
     of Florida Statutes Section 517.075 (Chapter 92-198, Laws of Florida).

          (xxix) When the Notes are issued and delivered pursuant to this
     Agreement, no Note will be of the same class (within the meaning of Rule
     144A under the Act) as securities of the Company or that are listed on a
     national securities exchange registered under Section 6 of the Exchange Act
     or that are quoted in a United States automated inter-dealer quotation
     system. The Company has been advised that the Notes have been designated
     PORTAL eligible securities in accordance with the rules and regulations of
     the NASD.

          (xxx) Each of the Operative Documents (other than the Notes, the
     Exchange Notes and the Private Exchange Notes) has been duly and validly
     authorized by the Company and, when duly executed and delivered by the
     Company, will be the legal, valid and binding obligation of the Company,
     enforceable against the Company in accordance with its terms, except as (i)
     the enforceability thereof may be limited by applicable bankruptcy,
     insolvency, fraudulent conveyance, reorganization or similar laws affecting
     the rights of creditors generally and (ii) rights of acceleration and the
     availability of equitable remedies may be limited by general principles of
     equity. The Offering Memorandum contains an accurate summary in all
     material respects of the terms of each of the Operative Documents.

          (xxxi) The Notes have been duly and validly authorized by the 
     Company for issuance and sale to the Initial Purchasers pursuant to this
     Agreement and, when issued and authenticated in accordance with the terms
     of the Indenture and delivered against payment therefor in accordance with
     the terms hereof and thereof, will be the legal, valid and binding
     obligations of the Company, enforceable against the Company in accordance
     with their terms and entitled to the benefits of the Indenture, except as
     (i) the enforceability thereof may be limited by applicable bankruptcy,
     insolvency, fraudulent conveyance, reorganization or similar laws affecting
     the rights of creditors generally and (ii) rights of acceleration and the
     availability of equitable remedies may be limited by general principles of
     equity.

     Company, enforceable against the Company in accordance with their terms and
     entitled to the benefits of the Indenture, except as (i) the enforceability
     thereof may be limited by applicable bankruptcy, insolvency, fraudulent

          (xxxiii) No registration under the Act of the Notes is required for
     the sale of the Notes to the Initial Purchasers as contemplated hereby or
     for the Exempt Resales assuming (A) that the purchasers who buy the Notes
     in the Exempt Resales are either QIBs or Accredited Investors and (B) the
     accuracy of the representations of the Initial Purchasers regarding the
     absence of general solicitation in connection with the sale of Notes to the
     Initial Purchasers and Exempt Resales contained herein. No form of general
     solicitation or general advertising (as those terms are used in Regulation
     D under the Act) was used by the Company or any of its representatives
     (other than



                                       16

<PAGE>   18



     the Initial Purchasers, as to which the Company makes no representation or
     warranty) in connection with the offer and sale of any of the Notes in
     connection with Exempt Resales, including, but not limited to, articles,
     notices or other communications published in any newspaper, magazine, or
     similar medium or broadcast over television or radio, or any seminar or
     meeting whose attendees have been invited by any general solicitation or
     general advertising. None of the Company, its subsidiaries or affiliates
     (as defined in Rule 501(b) under the Act) has, directly or through any
     agent, sold, offered for sale, solicited offers to buy or otherwise
     negotiated in respect of any security that is or will be integrated with
     the sale of the Notes in a manner that would require the registration of
     the Notes under the Act.

          (xxxiv) Set forth on EXHIBIT A hereto is a list of each funded
     employee pension or benefit plan, as defined in Article 3, Section 2(A) of
     ERISA and qualified under Section 401(a) of the Internal Revenue Code, with
     respect to which the Company or any of its subsidiaries, or any corporation
     considered an affiliate of any of them within the meaning of Section
     407(d)(7) of ERISA, is a party in interest or disqualified person.

          (xxxv) None of the execution, delivery and performance of this
     Agreement, the issuance and sale of the Notes, the application of the
     proceeds from the issuance and sale of the Notes and the consummation of
     the transactions contemplated thereby as set forth in the Offering
     Memorandum, will violate Regulations G, T, U or X promulgated by the Board
     of Governors of the Federal Reserve System or analogous foreign laws and
     regulations.

          The Company acknowledges that the Initial Purchasers and, for purposes
of the opinions to be delivered to the Initial Purchasers pursuant to Section 8
hereof, counsel for the Company and counsel for the Initial Purchasers, will
rely upon the accuracy and truth of the foregoing representations and hereby
consent to such reliance.

     (b)  Each Initial Purchaser, severally and not jointly, represents, 
warrants and covenants to the Company and agrees that:

          (i)   Such Initial Purchaser is a QIB, with such knowledge and
     experience in financial and business matters as are necessary in order to
     evaluate the merits and risks of an investment in the Notes.

          (ii)  Such Initial Purchaser (A) is not acquiring the Notes with a 
     view to any distribution thereof that would violate the Act or the 
     securities laws of any state of the United States or any other applicable 
     jurisdiction and (B) will be reoffering and reselling the Notes only to 
     QIBs in reliance on the exemption from the registration requirements of 
     the Act provided by Rule 144A and to Accredited Investors in a private 
     placement exempt from the registration requirements of the Act.

          (iii) No form of general solicitation or general advertising has been
     or will be used by such Initial Purchaser or any of its representatives in
     connection with the offer and sale of any of the Notes, including, but not
     limited to, articles, notices or other communications published in any
     newspaper, magazine, or similar medium or broadcast over television or
     radio, or any


                                       17

<PAGE>   19



     seminar or meeting whose attendees have been invited by any general
     solicitation or general advertising.

          (iv) Such Initial Purchaser agrees that, in connection with the Exempt
     Resales, it will solicit offers to buy the Notes only from, and will offer
     to sell the Notes only to, QIBs and Accredited Investors. Such Initial
     Purchaser further agrees (A) that it will offer to sell the Notes only to,
     and will solicit offers to buy the Notes only from (1) QIBs who in
     purchasing such Notes will be deemed to have represented and agreed that
     they are purchasing the Notes for their own accounts or accounts with
     respect to which they exercise sole investment discretion and that they or
     such accounts are QIBs and (2) Accredited Investors who make the
     representations contained in, and execute and return to such Initial
     Purchaser, a certificate in the form of ANNEX A attached to the Offering
     Memorandum and (B) that, in the case of such QIBs and Accredited Investors,
     acknowledges and agrees that such Notes will not have been registered under
     the Act and may be resold, pledged or otherwise transferred only (1) to the
     Company, (2) to a person whom the seller reasonably believes is a QIB
     purchasing for its own account or for the account of another QIB in
     compliance with the resale provisions of Rule 144A under the Act, (3) to an
     institutional Accredited Investor that, prior to such transfer, furnishes
     to the Trustee a written certification containing certain representations
     and agreements relating to the restrictions on transfer of such Notes, (4)
     pursuant to the resale limitations provided by Rule 144 under the Act, if
     available, (5) pursuant to and effective registration statement under the
     Act, (6) outside the United States to a foreign person in a transaction
     meeting the requirements of Regulation S under the Act or (7) pursuant to
     any other available exemption from the registration requirements of the
     Act, and, in each case, in accordance with any applicable securities laws
     of any state of the United States or any other applicable jurisdiction and
     (c) that the holder will, and each subsequent holder is required to, notify
     any purchaser of the security evidenced thereby of the resale restrictions
     set forth in (B) above.

          Each Initial Purchaser understands that the Company and, for purposes
of the opinions to be delivered to the Initial Purchasers pursuant to Section 8
hereof, counsel for the Company and counsel for the Initial Purchasers will rely
upon the accuracy and truth of the foregoing representations, and hereby
consents to such reliance.

     6.   Indemnification.
          ---------------

          (a) The Company agrees to indemnify and hold harmless each Initial
Purchaser, its officers, directors, partners, employees, agents and counsel, and
each person, if any, who controls such Initial Purchaser within the meaning of
Section 15 of the Act or Section 20(a) of the Exchange Act, against any and all
losses, liabilities, claims, damages and expenses whatsoever (including but not
limited to attorneys' fees and any and all expenses whatsoever reasonably
incurred in investigating, preparing or defending against any litigation,
commenced or threatened, or any claim whatsoever, and any and all amounts paid
in settlement of any claim or litigation), joint or several, to which they or
any of them may become subject under the Act, the Exchange Act, any state
securities or Blue Sky law or otherwise, insofar as such losses, liabilities,
claims, damages, obligations, penalties, judgments, awards, costs, disbursements
or expenses (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in the
Preliminary Offering Memorandum or the Offering Memorandum, or in any supplement
thereto or amendment thereof, or arise



                                       18

<PAGE>   20



out of or are based upon the omission or alleged omission to state therein any
material fact required to be stated therein or necessary to make the statements
therein not misleading; PROVIDED, HOWEVER, that (i) the Company will not be
liable to an Initial Purchaser in any such case to the extent, but only to the
extent, that any such loss, liability, claim, damage, obligation, penalty,
judgment, award, cost, disbursement or expense arises out of or is based upon
any such untrue statement or alleged untrue statement or omission or alleged
omission made therein in reliance upon and in conformity with written
information furnished to the Company by or on behalf of such Initial Purchaser
expressly for use therein and (ii) the indemnity agreement contained in this
Section 6(a) with respect to any Preliminary Offering Memorandum (or the
Offering Memorandum) shall not inure to the benefit of an Initial Purchaser (or
to the benefit of any person controlling such Initial Purchaser) from whom the
person asserting any such losses, liabilities, claims, damages or expenses
purchased the Notes which is the subject thereof if at or prior to the written
confirmation of the sale of such Notes a copy of the Offering Memorandum (or the
Offering Memorandum as amended or supplemented) was not sent or delivered to
such person and the untrue statement or omission of a material fact contained in
such Preliminary Offering Memorandum (or the Offering Memorandum) was corrected
in the Offering Memorandum (or the Offering Memorandum as amended or
supplemented) and delivery of such Offering Memorandum (or the Offering
Memorandum as amended or supplemented) would have eliminated any such loss,
liability, claim, damage or expense unless the failure is the result of
non-compliance by the Company with Section 4(b) hereof; PROVIDED, HOWEVER, the
indemnity agreement in this Section 6(a) shall not apply to any portion of any
such loss, liability, claim, damage, obligation, penalty, judgment, award, cost,
disbursement or expense to the extent it is found in a final judgment by a court
of competent jurisdiction (not subject to further appeal) to have resulted
primarily and directly from the gross negligence or willful misconduct of such
Initial Purchaser. This indemnity agreement will be in addition to any liability
which the Company may otherwise have including, without limitation, under this
Agreement.

          (b) Each Initial Purchaser agrees, severally and not jointly, to 
indemnify and hold harmless the Company, each of the directors of the Company,
and each other person, if any, who controls the Company within the meaning of
Section 15 of the Act or Section 20(a) of the Exchange Act, against any losses,
liabilities, claims, damages and expenses whatsoever as incurred (including but
not limited to attorneys' fees and any and all expenses whatsoever incurred in
investigating, preparing or defending against any litigation, commenced or
threatened, or any claim whatsoever, and any and all amounts paid in settlement
of any claim or litigation), joint or several, to which they or any of them may
become subject under the Act, the Exchange Act or otherwise, insofar as such
losses, liabilities, claims, damages or expenses (or actions in respect thereof)
are based upon any untrue statement or alleged untrue statement of a material
fact contained in the Preliminary Offering Memorandum or the Offering Memorandum
or in any amendment thereof or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
in each case to the extent, but only to the extent, that any such loss,
liability, claim, damage or expense arises out of or is based upon any such
untrue statement or alleged untrue statement or omission or alleged omission
made therein in reliance upon and in conformity with written information
furnished to the Company by or on behalf of such Initial Purchaser expressly for
use therein; PROVIDED, HOWEVER, that in no case shall any Initial Purchaser be
liable or responsible for any amount in excess of the discounts and commissions
applicable to the Notes purchased by such Initial Purchaser hereunder. This
indemnity will be in addition to any liability which the Initial Purchasers may
otherwise have including, without limitation, under this Agreement.



                                       19

<PAGE>   21



          (c) Promptly after receipt by an indemnified party under subsection 
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify each party against whom
indemnification is to be sought in writing of the commencement thereof (but the
failure to so notify an indemnifying party shall not relieve it from any
liability which it may have under this Section 6 except to the extent the
indemnifying party is materially prejudiced by such failure). In case any such
action is brought against any indemnified party, and it notifies an indemnifying
party of the commencement thereof, the indemnifying party will be entitled to
participate therein, and to the extent it may elect by written notice delivered
to the indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof with counsel reasonably
satisfactory to such indemnified party. Notwithstanding the foregoing, the
indemnified party or parties shall have the right to employ its or their own
counsel in any such case, but the fees and expenses of such counsel shall be at
the expense of such indemnified party or parties unless (i) the employment of
such counsel shall have been authorized in writing by one of the indemnifying
parties in connection with the defense of such action, (ii) the indemnifying
parties shall not have employed counsel to have charge of the defense of such
action within a reasonable time after notice of commencement of the action, or
(iii) such indemnified party or parties shall have reasonably concluded that
there may be defenses available to it or them which are different from or
additional to those available to one or all of the indemnifying parties (in
which case all indemnified parties having consistent interests, and such
different or additional defenses, shall be entitled to engage one additional
counsel in each jurisdiction to direct such different or additional defenses),
in any of which events such fees and expenses shall be borne by the indemnifying
parties. In no event will the indemnifying parties hereunder be responsible for
the fees and expenses of more than one such counsel (together with appropriate
local counsel). Anything in this subsection to the contrary notwithstanding, an
indemnifying party shall not be liable for any settlement of any claim or action
effected without its written consent; PROVIDED, HOWEVER, that such consent was
not unreasonably withheld.

     7.   CONTRIBUTION. In order to provide for contribution in circumstances in
which the indemnification provided for in Section 6 hereof is for any reason
unavailable from any indemnifying party or is insufficient to hold harmless a
party indemnified thereunder, then each indemnifying party shall contribute to
the aggregate losses, claims, damages, liabilities and expenses of the nature
contemplated by such indemnification provision (including without limitation any
investigation, legal and other expenses reasonably incurred in connection with,
and any amount paid in settlement of, any action, suit or proceeding or any
claims asserted, but after deducting in the case of losses, claims, damages,
liabilities and expenses suffered by the Company, any contribution received by
the Company from persons, other than the Initial Purchasers, who may also be
liable for contribution, including persons who control the Company within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, and
directors of the Company) as incurred to which the Company and the Initial
Purchasers may be subject, in such proportions 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 Notes or, if such
allocation is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to above but also
the relative fault of the Company, on the one hand, and the Initial Purchasers,
on the other hand, in connection with the statements or omissions which resulted
in such losses, claims, damages, liabilities or expenses, 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 hand, shall
be deemed to be in the same proportion as (x) the total proceeds from the
offering (net of discounts and commissions but before deducting expenses)
received by the


                                       20

<PAGE>   22



Company, and (y) the discounts and commissions received by the Initial
Purchasers, in each case as set forth in the table on the cover page of the
Offering Memorandum, bear to the aggregate offering price of the Notes. The
relative fault of the Company, on the one hand, and the Initial Purchasers, on
the other hand, shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or an Initial Purchaser 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 or by any other method of allocation which does not take account
of the equitable considerations referred to above. Notwithstanding the
provisions of this Section 7, (i) in no case shall an Initial Purchaser be
liable or responsible for any contribution obligation in excess its proportional
share, based upon the proportion of the aggregate principal amount of Notes
purchased by it set forth opposite its name on Schedule I hereto, of the total
discounts and commissions set forth in the table on the cover page of the
Offering Memorandum, and (ii) no person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 7, each person, if any, who
controls an Initial Purchaser within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act shall have the same rights to contribution as
such Initial Purchaser controlled by it, and each person, if any, who controls
the Company within the meaning of Section 15 of the Act or Section 20(a) of the
Exchange Act, and each director of the Company shall have the same rights to
contribution as the Company, subject in each case to clauses (i) and (ii) of the
immediately preceding sentence. Any party entitled to contribution will,
promptly after receipt of notice of commencement of any action, suit or
proceeding against such party in respect of which a claim for contribution may
be made against another party or parties, notify each party or parties from whom
contribution may be sought, but the omission to so notify such party or parties
shall not relieve the party or parties from whom contribution may be sought from
any obligation it or they may have under this Section 7 (except to the extent
such party or parties from whom contribution may be sought is materially
prejudiced by such failure) or otherwise. No party shall be liable for
contribution with respect to any action or claim settled without consent;
PROVIDED, HOWEVER, that such consent was not unreasonably withheld.

     8.   CONDITIONS TO THE OBLIGATIONS OF THE INITIAL PURCHASERS. The 
obligations of the Initial Purchasers to purchase and pay for the Notes, as
provided herein, shall be subject to the satisfaction of the following
conditions precedent:

          (a) All of the representations and warranties of the Company contained
     in this Agreement shall be true and correct in all material respects on the
     date hereof and on the Closing Date with the same force and effect as if

     Company shall have performed or complied in all material respects with all
     of the agreements herein contained and required to be performed or complied
     with by it at or prior to the Closing Date.

          (b) The Offering Memorandum shall have been printed and copies
     distributed to the Initial Purchasers on the day following the date of this
     Agreement or at such later date and time as to which the Initial Purchasers
     may agree, and no stop order suspending the qualification or exemption from
     qualification of the Notes in any jurisdiction referred to in Section 4(e)
     shall have


                                       21

     contemplated in the Offering Memorandum, the effect of which, in any such
     case described in clause (i) or (ii) of this Section 8(c), in the

     any such rating or of a possible change in any such rating that does not
     indicate the direction of the possible change.

          All opinions, certificates, letters and other documents required by 
this Section 8 to be delivered by the Company will be in compliance with the
provisions hereof only if they are reasonably satisfactory in form and substance

survive delivery of and payment for the Notes to and by the Initial Purchasers.
The representations contained in Section 5 and the agreements contained in

Agreement at any time prior to the Closing Date by notice to the Company from
the Initial Purchasers, without liability (other than with respect to Sections
4(f), 6, 7 and 17, which shall remain in effect) to the Company on the part of
the Initial Purchasers if, on or prior to such date, (i) the Company shall have
failed, refused or been unable to perform in any material respect any agreement
on its part to be performed hereunder, (ii) any other condition to the
obligations of the Initial Purchasers hereunder as provided in Section 8 is not

information is given in the Offering Memorandum in the condition (financial or
otherwise), business, properties, assets, liabilities, prospects, net worth,
results of operations or cash flows of the Company and its subsidiaries, taken
as a whole, whether or not arising in the ordinary course of business other than
as set forth in the Offering Memorandum, such as, in the judgment of the Initial
Purchasers, makes it inadvisable or impracticable to proceed with the Offering
or delivery of the Notes as contemplated hereby and by the Offering Memorandum,
or (iv)(A) any domestic or international event or act or occurrence has
materially disrupted, or in the opinion of the Initial Purchasers will in the
immediate future materially disrupt, the market for the Company's securities or
for securities in general; or (B) trading in securities on the New York or
American Stock Exchanges or over-the-counter market shall have been generally
suspended or materially limited, or minimum or maximum prices shall have been

(D) there is an outbreak or escalation of armed hostilities involving the United
States on or after the date hereof, or there has been a declaration by the

to proceed with the offering or delivery of the Notes on the terms and in the
manner


                                       24

contemplated in the Offering Memorandum; or (E) there shall have occurred such a
material adverse change in general economic, political or financial conditions
or the effect of international conditions on the financial markets in the United

Notes as contemplated hereby and by the Offering Memorandum.

          (c) Any notice of termination pursuant to this Section 11 shall be by
telephone, telex, telephonic facsimile, or telegraph, confirmed in writing by
letter.

          (d) If this Agreement shall be terminated pursuant to any of the 
provisions hereof (other than pursuant to Section 11(b) (except clauses (i) and
(ii) thereof)), or if the sale of the Notes provided for herein is not
consummated because any condition to the obligations of the Initial Purchasers
set forth herein is not satisfied or because of any refusal, inability or
failure on the part of the Company to perform any agreement herein or comply
with any provision hereof, the Company will reimburse the Initial Purchasers for
all out-of-pocket expenses (including the reasonable fees and expenses of
counsel to the Initial Purchasers), incurred by the Initial Purchasers in
connection herewith.

     12.  DEFAULT BY AN INITIAL PURCHASER. If one of the Initial Purchasers 
shall fail at the Closing Date to purchase the Notes that it is obligated to
purchase under the terms of this Agreement, the other Initial Purchasers shall
have the right, but not the obligation, within 24 hours thereafter, to make
arrangements to purchase all, but not less than all, of such Notes upon the
terms herein set forth; if, however, the other Initial Purchaser(s) shall not
have completed such arrangements within such 24-hour period, then this Agreement
shall terminate without liability on the part of any nondefaulting Initial
Purchaser. No action pursuant to this Section shall relieve any defaulting
Initial Purchaser from liability in respect of its default. In the event of any
such default that does not result in a termination of this Agreement, either a
nondefaulting Initial Purchaser or the Company shall have the right to postpone
the Closing Date for a period not exceeding seven days to effect any required
changes in the Offering Memorandum or in any other documents or arrangement.

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

          (a) EXCHANGE OFFER. To the extent not prohibited by any applicable law
     or applicable interpretation of the staff of the Commission, the Company
     shall, for the benefit of the Holders, at the Company's cost, use its best
     efforts to cause to be filed with the Commission an Exchange Offer
     Registration Statement on or prior to 45 days after the Closing Date on an
     appropriate form under the Act covering the offer by the Company to the
     Holders to exchange all of the Registrable Securities (other than Private
     Exchange Notes) for a like aggregate principal amount of Exchange Notes, to
     cause such Exchange Offer Registration Statement to be declared effective
     under the Act by the Commission on or prior to 120 days after the Closing
     Date, to cause such Registration Statement to remain effective until the
     closing of the Exchange Offer and to cause the Exchange Offer to be
     consummated on or prior to 45 days after the date on which the Exchange
     Offer Registration Statement was declared effective under the Act by the
     Commission. The Exchange Notes will be issued under the Indenture. Upon the
     effectiveness of the Exchange Offer Registration Statement, the Company
     shall promptly commence the Exchange Offer, it being the objective of such
     Exchange Offer to enable each Holder (other than Participating
     Broker-Dealers (as defined in Section 3(t) hereof)) eligible and electing
     to exchange Registrable Securities for Exchange Notes (assuming that such
     Holder is not an affiliate of the Company within the meaning of Rule 405
     under the Act, acquires the Exchange Notes in the ordinary course of such
     Holder's business and has no arrangements or understandings with any Person
     to participate in the Exchange Offer for the purpose of distributing the
     Exchange Notes) to transfer such Exchange Notes from and after their
     receipt without any limitations or restrictions under the Act or under
     state securities or blue sky laws.

          In connection with the Exchange Offer, the Company shall

          (i) mail to each Holder a copy of the Prospectus forming part of the
     Exchange Offer Registration Statement, together with an appropriate letter
     of transmittal and related documents;



                                       5

<PAGE>   39


          (ii)  keep the Exchange Offer open for acceptance for a period of not
     less than 30 days after the date notice thereof is mailed to the Holders,
     or longer if required by applicable law (such period being referred to
     herein as the "EXCHANGE PERIOD");

          (iii) utilize the services of the Depository for the Exchange Offer;

          (iv) permit Holders to withdraw tendered Notes at any time prior to
     the close of business, New York City time, on the last business day of the
     Exchange Period, by sending to the institution specified in the notice a
     telegram, telex, facsimile transmission or letter setting forth the name of
     such Holder, the principal amount of Notes delivered for exchange, and a
     statement that such Holder is withdrawing its election to have such Notes
     exchanged;

          (v)   notify each Holder that any Note not tendered will remain
     outstanding and continue to accrue interest, but will not retain any rights
     under this Agreement (except in the case of the Initial Purchasers and
     Participating Broker-Dealers as provided herein); and

          (vi)  otherwise comply in all respects with all applicable laws
     relating to the Exchange Offer.

          If, prior to consummation of the Exchange Offer, any 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 Notes in the Exchange
Offer, issue and deliver to such Initial Purchaser in exchange (the "PRIVATE
EXCHANGE") for Notes held by the Initial Purchasers a like principal amount of
debt securities of the Company that are identical (except that such securities
shall bear appropriate transfer restrictions) to the Exchange Notes (the
"PRIVATE EXCHANGE NOTES") and which are issued pursuant to the Indenture (which
will provide that the Exchange Notes will not be subject to the transfer
restrictions set forth in the Indenture and that the Exchange Notes, the Private
Exchange Notes and the Notes will vote and consent together on all matters as
one class and that none of the Exchange Notes, the Private Exchange Notes or the
Notes will have the right to vote or consent as a separate class on any matter).
The Private Exchange Notes shall be of the same series as and shall bear the
same CUSIP number as the Exchange Notes.

          As soon as practicable after the close of the Exchange Offer or the 
Private Exchange, as the case may be, the Company shall:

          (i) accept for exchange all Notes or portions thereof duly tendered
     and not validly withdrawn pursuant to the Exchange Offer;


                                       6

<PAGE>   40


          (ii)  accept for exchange all Notes or portions thereof duly tendered
     pursuant to the Private Exchange; and

          (iii) deliver, or cause to be delivered, to the Trustee for
     cancellation all Notes or portions thereof so accepted for exchange by the
     Company, and issue, and cause the Trustee to promptly authenticate and
     deliver to each Holder, a new Exchange Note or Private Exchange Note, as
     the case may be, equal in principal amount to the principal amount of the
     Notes surrendered by such Holder.

          To the extent not prohibited by applicable law or any applicable
interpretation of the staff of the Commission, the Company shall use its best
efforts to complete the Exchange Offer as provided above, and shall comply with
all applicable requirements of the Act, the Exchange Act and other applicable
laws in connection with the Exchange Offer. The Exchange Offer shall not be
subject to any condition, other than that (i) the Exchange Offer does not
violate any applicable law or interpretation of the staff of the Commission,
(ii) no action or proceeding has been instituted or threatened in any court or
by or before any governmental agency with respect to the Exchange Offer which,
in the reasonable judgment of the Company, might impair the ability of the
Company to proceed with the Exchange Offer, (iii) there has not been any
material change, or development involving a prospective material change, in the
business or financial affairs of the Company or any of its subsidiaries which,
in the reasonable judgment of the Company, would materially impair the Company's
ability to consummate the Exchange Offer or have a material adverse effect on
the Company if the Exchange Offer is consummated, (iv) there has not been
proposed, adopted, or enacted any law, statute, rule or regulation which, in the
reasonable judgment of the Company, might materially impair the ability of the
Company to proceed with the Exchange Offer or have a material adverse effect on
the Company if the Exchange Offer is consummated or (v) all governmental
approvals which the Company shall reasonably deem necessary for the consummation
of the Exchange Offer as contemplated shall have been obtained. Each Holder of
Registrable Securities who wishes to exchange such Registrable Securities for
Exchange Notes in the Exchange Offer will be required to make certain customary
representations in connection therewith, including representations that such
Holder is not an affiliate of the Company within the meaning of Rule 405 under
the Act, that any Exchange Notes to be received by it will be acquired in the
ordinary course of business and that at the time of the commencement of the
Exchange Offer it had no arrangement with any Person to participate in the
distribution (within the meaning of the Act) of the Exchange Notes and will be
required to make such other representations as may be necessary under
applicable Commission rules, regulations or interpretations to render available
the use of Form S-4 or any other appropriate form under the Act. The Company
shall inform the Initial Purchasers, after consultation with the Trustee and the
Initial Purchasers, of the names and addresses of the Holders to whom the
Exchange Offer is made, and the Initial Purchasers shall have the right to
contact such Holders and otherwise facilitate the tender of Registrable
Securities in the Exchange Offer.


                                       7

<PAGE>   41



          In the event that the Company is unable to consummate the Exchange 
Offer due to any event listed in clauses (i) through (v) in the paragraph
immediately above, the Company shall not be deemed to have breached any covenant
under this Section 2(a).

          Upon consummation of the Exchange Offer in accordance with this 
Section 2(a), the provisions of this Agreement shall continue to apply, MUTATIS
MUTANDIS, solely with respect to Registrable Securities that are Private
Exchange Notes and Exchange Notes held by Participating Broker-Dealers, and the
Company shall have no further obligation to register Registrable Securities
(other than Private Exchange Notes) pursuant to Section 2(b) of this Agreement.

          (b) SHELF REGISTRATION. In the event that (i) the Company is not 
permitted to commence or accept tenders pursuant to the Exchange Offer because
the Exchange Offer is not permitted by applicable law or Commission policy, (ii)
any Holder of Transfer Restricted Securities notifies the Company within 20
business days after the consummation of the Exchange Offer that (a) it is
prohibited by law or Commission policy from participating in the Exchange Offer,
(b) that it may not resell the Exchange Notes acquired by it in the Exchange
Offer to the public without delivering a prospectus and the prospectus contained
in the Exchange Offer Registration Statement is not appropriate or available for
such resales or (c) that it is a broker-dealer and owns Notes acquired directly
from the Company or an affiliate of the Company, or (iii) the Exchange Offer is
not for any other reason consummated within 165 days of the Closing Date, the
Company shall, at its cost, cause to be filed with the Commission as promptly as
practicable after such determination or date, as the case may be, and, in any
event, on or prior to 45 days thereafter, a Shelf Registration Statement
providing for the sale by the Holders of all of the Registrable Securities, and
shall use its best efforts to cause such Shelf Registration Statement declared
effective by the Commission on or prior to 90 days after such determination or
date. No Holder of Registrable Securities may include any of its Registrable
Securities in any Shelf Registration pursuant to this Agreement unless and until
such Holder furnishes to the Company in writing, within 15 days after receipt of
a request therefor, such information as the Company may, after conferring with
counsel with regard to information relating to Holders that would be required by
the Commission to be included in such Shelf Registration Statement or Prospectus
included therein, reasonably request for inclusion in any Shelf Registration
Statement or Prospectus included therein. Each Holder as to which any Shelf
Registration is being effected agrees to furnish promptly to the Company all
information required to be disclosed in the applicable Shelf Registration
Statement or Prospectus included therein by the rules and regulations of the
Commission applicable to the Shelf Registration Statement in order to make the
information previously furnished to the Company by such Holder not materially
misleading.

          The Company agrees, subject to applicable law or applicable 
interpretation of the staff of the Commission, to use its reasonable best
efforts to keep the Shelf Registration Statement continuously effective,
supplemented and amended under the Act for a period ending on the earlier of the
date which is two years from the Closing Date (subject



                                       8

<PAGE>   42



to extension pursuant to the last paragraph of Section 3) or the date on which
all of the Registrable Securities covered by the Shelf Registration Statement
have been sold pursuant to the Shelf Registration Statement or cease to be
outstanding (the "EFFECTIVENESS PERIOD"). The Company shall not permit any
securities other than Registrable Securities to be included in the Shelf
Registration. The Company will, in the event a Shelf Registration Statement is
declared effective, provide to each Holder 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 customary to permit unrestricted resales of the Registrable Securities
covered by the Shelf Registration Statement. The Company further agrees, if
necessary, to use its reasonable best efforts to supplement or amend the Shelf
Registration Statement, if required by the Act or the rules, regulations or
instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or by any other rules and regulations thereunder
for shelf registrations, or if reasonably requested by the Majority Holders, and
the Company agrees to furnish to the Holders copies of any such supplement or
amendment promptly after its being used or filed with the Commission.

          (c) EXPENSES. The Company shall pay all Registration Expenses in 
connection with registrations pursuant to Section 2(a) or 2(b). Each Holder
shall pay all expenses of its counsel (other than the fees described in clauses
(i) and (ii) of the definition of "Registration Expenses"), underwriting
discounts and commissions and transfer taxes, if any, relating to the sale or
disposition of such Holder's Registrable Securities pursuant to the Exchange
Offer Registration Statement and the Shelf Registration Statement.

          (d) EFFECTIVE REGISTRATION STATEMENT. An Exchange Offer Registration
Statement pursuant to Section 2(a) hereof or a Shelf Registration Statement
pursuant to Section 2(b) hereof will not be deemed to have become effective
unless it has been declared effective by the Commission; PROVIDED, HOWEVER, that
if, after it has been declared effective, the offering of Registrable Securities
pursuant to a Shelf Registration Statement is interfered with by any stop order,
injunction or other order or requirement of the Commission or any other
governmental agency or court, such Registration Statement will be deemed not to
have been effective during the period of such interference, until the offering
of Registrable Securities pursuant to such Registration Statement may legally
resume.

          (e) LIQUIDATED DAMAGES. In the event that an Exchange Offer 
Registration Statement has not been filed with the Commission on or prior to 45
days after the Closing Date, additional interest payable by the Company as
liquidated damages ("LIQUIDATED DAMAGES") will accrue on the Notes from and
including the 31st day after the Closing Date until but excluding the date such
Exchange Offer Registration Statement is filed. In addition, if on or prior to
120 days after the Closing Date, such Exchange Offer Registration Statement is
not declared effective under the Act by the Commission, Liquidated Damages will
accrue on the Notes from and including the 121st day after the Closing Date
until but excluding the date such Exchange Offer Registration Statement is
declared effective. Further, if on or prior to 45 days after the date specified
for effectiveness of the Exchange Offer Registration



                                       9
<PAGE>   43



Statement the Exchange Offer is not consummated, Liquidated Damages will accrue
on the Notes from and including the 46th day after the date specified for
effectiveness of the Exchange Offer Registration Statement, but excluding, the
consummation of the Exchange Offer. If a Shelf Registration Statement is
required to be filed pursuant to Section 2(b) and such Shelf Registration
Statement is not filed or declared effective within the time periods provided by
Section 2(b) hereof for such filing or declaration, Liquidated Damages will
accrue on the Notes (other than those exchanged in the Exchange Offer) or the
Private Exchange Notes, as the case may be, from and including the day
immediately following such default until but excluding the effective date of the
Shelf Registration Statement. Further, if the Shelf Registration Statement or
the Exchange Offer Registration Statement is declared effective but thereafter
ceases to be effective or usable during the time periods specified in this
Agreement, Liquidated Damages will accrue on the Notes (other than those
exchanged in the Exchange Offer) or the Private Exchange Notes, as the case may
be, from and including the day immediately following such default until but
excluding the date such Registration Statement becomes effective or usable. In
each case, such Liquidated Damages will be payable in cash semiannually in
arrears, with the first semiannual payment due on the first interest payment
date in respect of the Notes (or the Private Exchange Notes) following the date
from which Liquidated Damages begin to accrue, and will accrue, under each
circumstance set forth above at a rate per annum equal to an additional one half
of one percent (0.50%) of the principal amount of the Notes (or the Private
Exchange Notes) upon the occurrence of each such circumstance, which rate will
increase by one half of one percent (0.50%) for each 90-day period that such
Liquidated Damages continue to accrue under any circumstance, with an aggregate
maximum increase in the interest rate per annum equal to two percent (2.00%).

          Upon the filing of the Exchange Offer Registration Statement, the
effectiveness of the Exchange Offer Registration Statement, or the consummation
of the Exchange Offer, as the case may be, the interest rate borne by the Notes
will be reduced by the full amount of any such increase to the extent that such
increase related to the failure of any such event to have occurred. Upon the
effectiveness of a Shelf Registration Statement, the interest rate borne by the
Notes (and the Private Exchange Notes) shall be reduced, from and as of the date
of such effectiveness, to the original interest rate of the Notes unless and
until increased as described above. Notwithstanding anything to the contrary
contained herein, the Company (i) shall not be required to amend or supplement
the Shelf Registration Statement, any related prospectus or any document
incorporated therein by reference and (ii) may suspend the effectiveness of any
such Shelf Registration Statement in the event that, and for a period not to
exceed, for so long as this Agreement is in effect, an aggregate of 90 days in
any one calendar year if (A) an event occurs and is continuing as a result of
which the Shelf Registration Statement, any related prospectus or any document
incorporated therein by reference as then amended or supplemented would, in the
Company's good faith judgment, contain an untrue statement of a material fact or
omit to state a material fact necessary in order to make the statements therein
not misleading, and (B) the Company determines in its good faith judgment that
the disclosure of such event at such time would have a material adverse effect
on the business, operations or prospects of the Company;



                                       10

provided that any such suspension shall not relieve the Company from its
obligation to pay Liquidated Damages.

          The Company shall notify the Trustee within three business days after
each and every date on which an event occurs in respect of which Liquidated
Damages is required to be paid (an "EVENT DATE"). Liquidated Damages shall be
paid by depositing with the Trustee, in trust, for the benefit of the Holders of
Notes, Exchange Notes or Private Exchange Notes, as the case may be, on or
before the applicable semiannual interest payment date, immediately available
funds in sums sufficient to pay the Liquidated Damages then due. The Liquidated
Damages due shall be payable on each interest payment date to the record Holder
of Notes entitled to receive the interest payment to be paid on such date as set
forth in the Indenture. Each obligation to pay Liquidated Damages shall be
deemed to accrue from and including the day following the applicable Event Date.

          (f) SPECIFIC ENFORCEMENT. Without limiting the remedies available to
the Initial Purchasers and the Holders, the Company acknowledges that any
failure by the Company to comply with its obligations under Section 2(a) and
Section 2(b) hereof would result in material irreparable injury to the Initial
Purchasers or the Holders for which there is no adequate remedy at law, that it
would not be possible to measure damages for such injuries precisely and that,
in the event of any such failure, the Initial Purchasers or any Holder may
obtain such relief as may be required to specifically enforce the Company's
obligations under Section 2(a) and Section 2(b) hereof.

          3. REGISTRATION PROCEDURES. In connection with the obligations of the
Company with respect to the Registration Statements pursuant to Sections 2(a)
and 2(b) hereof, the Company shall:

          (a) prepare and file with the Commission a Registration Statement or
     Registration Statements as prescribed by Sections 2(a) and 2(b) within the
     relevant time periods specified in Section 2 hereof on the appropriate form
     under the Act, which form (i) shall be selected by the Company, (ii) shall,
     in the case of a Shelf Registration, be available for the sale of the
     Registrable Securities by the selling Holders and (iii) shall comply as to
     form in all material respects with the requirements of the applicable form
     and include or incorporate by reference all financial statements required
     by the Commission to be filed therewith, and the Company shall use its best
     efforts to cause such Registration Statement to become effective and remain
     effective in accordance with Section 2; PROVIDED, HOWEVER, that if (1) such
     filing is pursuant to Section 2(b), or (2) a Prospectus contained in an
     Exchange Offer Registration Statement filed pursuant to Section 2(a) is
     required to be delivered under the Act by any Participating Broker-Dealer
     who seeks to sell Exchange Notes, before filing any Registration Statement
     or Prospectus or any amendments or supplements thereto, the Company, if
     requested, shall furnish to and afford the Holders 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


                                       11

<PAGE>   45



     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 at least five business days prior to such filing. The
     Company shall not file any Registration Statement or Prospectus or any
     amendments or supplements thereto in respect of which the Holders, pursuant
     to this Agreement, must be afforded an opportunity to review prior to the
     filing of such document, if the Majority Holders or such Participating
     Broker-Dealer, as the case may be, their counsel or the managing
     underwriters, if any, shall reasonably object;

          (b) subject to Section 3(a) hereof, prepare and file with the
     Commission such amendments and post-effective amendments to each
     Registration Statement as may be necessary to keep such Registration
     Statement effective for the Effectiveness Period or the Applicable Period,
     as the case may be, and cause each Prospectus to be supplemented by any
     required prospectus supplement and as so supplemented to be filed pursuant
     to Rule 424 (or any similar provision then in force) under the Act, and
     comply with the provisions of the Act, the Exchange Act and the rules and
     regulations promulgated thereunder applicable to it with respect to the
     disposition of all securities covered by each Registration Statement during
     the Effectiveness Period or the Applicable Period, as the case may be, in
     accordance with the intended method or methods of distribution by the
     selling Holders thereof described in this Agreement (including sales by any
     Participating Broker-Dealer);

          (c) in the case of a Shelf Registration, (i) notify each Holder, at
     least five business days prior to filing, that a Shelf Registration
     Statement with respect to the Registrable Securities is being filed and
     advising such Holder that the distribution of Registrable Securities will
     be made in accordance with the method selected by the Majority Holders,
     (ii) furnish to each Holder and to each underwriter of an underwritten
     offering of Registrable Securities, if any, without charge, as many copies
     of each Prospectus, including each preliminary Prospectus, and any
     amendment or supplement thereto and such other documents as such Holder or
     underwriter may reasonably request, in order to facilitate the public sale
     or other disposition of the Registrable Securities, and (iii) subject to
     the last paragraph of this Section 3, consent to the use of the Prospectus
     or any amendment or supplement thereto by each of the selling Holders in
     connection with the offering and sale of the Registrable Securities covered
     by the Prospectus or any amendment or supplement thereto, provided that
     such use complies with all applicable laws and regulations;

          (d) use its best efforts to register or qualify the Registrable
     Securities under all applicable state securities or "blue sky" laws of such
     jurisdictions as any Holder of Registrable Securities covered by a
     Registration Statement and each underwriter of an underwritten offering of
     Registrable Securities shall reasonably request by the time the applicable
     Registration Statement is declared effective by the Commission, and do any
     and all other acts and things which may be reasonably necessary or
     advisable to enable such Holder and underwriter to consummate the dis-



                                       12
<PAGE>   46



     position in each such jurisdiction of such Registrable Securities owned by
     such Holder; PROVIDED, HOWEVER, that the Company shall not be required to
     (i) qualify as a foreign partnership or foreign corporation or as a dealer
     in securities in any jurisdiction where it would not otherwise be required
     to qualify but for this Section 3(d), (ii) file any general consent to
     service of process in any jurisdiction where it would not otherwise be
     subject to such service of process or (iii) subject itself to taxation in
     any such jurisdiction if it is not then so subject;

          (e) in the case of (A) a Shelf Registration or (B) Participating
     Broker-Dealers who have notified the Company that they will be utilizing
     the Prospectus contained in the Exchange Offer Registration Statement as
     provided in Section 3(t) hereof, are seeking to sell Exchange Notes and are
     required to deliver Prospectuses, notify each Holder, or such Participating
     Broker-Dealers, as the case may be, their counsel and the managing
     underwriters, if any, promptly and, if requested by such Holder or
     Participating Broker-Dealer, confirm such notice in writing (i) when a
     Registration Statement has become effective and when any post-effective
     amendments and supplements thereto become effective, (ii) of any request by
     the Commission or any state securities authority for amendments and
     supplements to a Registration Statement or Prospectus or for additional
     information after the Registration Statement has become effective, (iii) of
     the issuance by the Commission or any state securities authority of any
     stop order suspending the effectiveness of a Registration Statement or the
     initiation of any proceedings for that purpose, (iv) in the case of a Shelf
     Registration, if, between the effective date of a Registration Statement
     and the closing of any sale of Registrable Securities covered thereby, the
     representations and warranties of the Company contained in any underwriting
     agreement, securities sales agreement or other similar agreement, if any,
     relating to such offering cease to be true and correct in all material
     respects, (v) if the Company receives any notification with respect to the
     suspension of the qualification of the Registrable Securities or the
     Exchange Notes to be sold by any Participating Broker-Dealer for offer or
     sale in any jurisdiction or the initiation of any proceeding for such
     purpose, (vi) of the happening of any event or the failure of any event to
     occur or the discovery of any facts or otherwise, during the period a Shelf
     Registration Statement is effective or the Applicable Period, as the case
     may be, which makes any statement made in the Shelf Registration Statement,
     the Exchange Offer Registration Statement or any related Prospectus untrue
     in any material respect or which causes such Registration Statement or
     Prospectus, as the case may be, to omit to state a material fact necessary
     to make the statements therein, in the light of the circumstances under
     which they were made, not misleading and (vii) the Company's reasonable
     determination that a post-effective amendment to the Registration Statement
     would be appropriate;

          (f) use its best efforts to obtain the withdrawal of any order
     suspending the effectiveness of a Registration Statement at the earliest
     possible moment;


                                       13

<PAGE>   47



          (g) in the case of a Shelf Registration, furnish to each Holder, upon
     request and without charge, at least one conformed copy of each
     Registration Statement and any post-effective amendment thereto (without
     documents incorporated therein by reference or exhibits thereto, unless
     requested);

          (h) in the case of a Shelf Registration, cooperate with the selling
     Holders to facilitate the timely preparation and delivery of certificates,
     if any, 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; and cause such Registrable Securities to be in
     such denominations (consistent with the provisions of the Indenture) and
     registered in such names as the selling Holders or the managing
     underwriters may reasonably request at least two business days prior to the
     closing of any sale of Registrable Securities;

          (i) subject to Section 3(a) hereof and the second paragraph of Section
     2(e) hereof, in the case of a Shelf Registration or an Exchange Offer
     Registration, upon the occurrence of any circumstance contemplated by
     Section 3(e)(ii), 3(e)(iii), 3(e)(iv), 3(e)(v), 3(e)(vi) or 3(e)(vii)
     hereof, use its best efforts to prepare a supplement or post-effective
     amendment to the Registration Statement and the related Prospectus or any
     document incorporated therein by reference or file any other required
     document so that, as thereafter delivered to the purchasers of the
     Registrable Securities, such Prospectus will not contain any untrue
     statement of a material fact or omit to state a material fact necessary to
     make the statements therein, in the light of the circumstances under which
     they were made, not misleading. The Company agrees to notify each Holder to
     suspend use of the Prospectus as promptly as practicable after the
     occurrence of any such circumstance, and each Holder hereby agrees to
     suspend use of the Prospectus until the Company has amended or supplemented
     the Prospectus to correct such misstatement or omission;

          (j) in the case of a Shelf Registration, furnish to each Holder of
     Registrable Securities, upon request and without charge, a reasonable
     number of copies of any document which is incorporated by reference into or
     is an exhibit to a Registration Statement or a Prospectus after the initial
     filing of a Registration Statement;

          (k) obtain a CUSIP number for all Exchange Notes or Registrable
     Securities, as the case may be, not later than the effective date of a
     Registration Statement, and provide the Trustee with printed certificates
     for the Exchange Notes or the Registrable Securities, as the case may be,
     in a form eligible for deposit with the Depository;

          (l) cause the Indenture to be qualified under the TIA in connection
     with the registration of the Exchange Notes or Registrable Securities, as
     the case may be, cooperate with the Trustee and the Holders to effect such
     changes to the Indenture


                                       14

<PAGE>   48



     as may be required for the Indenture to be so qualified in accordance with
     the terms of the TIA and execute, and use its best efforts to cause the
     Trustee to execute, all documents as may be required to effect such
     changes, and all other forms and documents required to be filed with the
     Commission to enable the Indenture to be so qualified in a timely manner;

          (m) in the case of a Shelf Registration, enter into such agreements
     (including underwriting agreements) as are customary in underwritten public
     offerings and take all such other appropriate actions as are reasonably
     requested in order to expedite or facilitate the registration or the
     disposition of such Registrable Securities, and in such connection, whether
     or not an underwriting agreement is entered into and whether or not the
     registration is an underwritten registration: (i) make such representations
     and warranties to Holders of such Registrable Securities and the
     underwriters (if any), with respect to the business of the Company and its
     subsidiaries and the Registration Statement, the Prospectus and all
     documents, if any, incorporated or deemed to be incorporated by reference
     therein, in each case, as are customarily made by issuers to underwriters
     in underwritten public offerings, and confirm the same if and when
     reasonably requested; (ii) obtain customary opinions of counsel to the
     Company and updates thereof in form and substance reasonably satisfactory
     to the managing underwriters (if any) and the Holders of a majority in
     principal amount of the Registrable Securities being sold, addressed to
     each selling Holder and the underwriters (if any) covering the matters
     customarily covered in opinions requested in underwritten public offerings
     and such other matters as may be reasonably requested by such Holders and
     underwriters; (iii) obtain "cold comfort" letters and updates thereof in
     form and substance reasonably satisfactory to the managing underwriters
     from the independent certified public accountants of the Company (and, if
     necessary, any other independent certified public accountants of any
     subsidiary of the Company or of any business acquired or to be acquired by
     the Company for which financial statements and financial data are, or are
     required to be, included in the Registration Statement), addressed to the
     selling Holders of Registrable Securities and 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 public offerings; and (iv) if an underwriting agreement is
     entered into, cause the same to contain indemnification provisions and
     procedures no less favorable than those set forth in Section 4 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;

          (n) if (a) a Shelf Registration is filed pursuant to Section 2(b) or
     (B) A Prospectus contained in an Exchange Offer Registration Statement
     filed pursuant to Section 2(a) is required to be delivered under the Act by
     any Participating

     Broker-Dealer who seeks to sell Exchange Notes 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 and its
     subsidiaries to supply all information in each case reasonably requested by
     any such Inspector in connection with such Registration Statement. Records
     which the Company determines, in good faith, to be confidential and as to
     which they notify the Inspectors are confidential shall not be disclosed by
     the Inspectors unless, after prior consultation with the Company, (i) the
     disclosure of such Records is necessary to avoid or correct a material
     misstatement or omission in such Registration Statement, (ii) the release
     of such Records is ordered pursuant to an effective 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, other than as a
     result of a breach of confidentiality or secrecy to the Company. 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, other than as a result of a breach of confidentiality or secrecy to
     the Company. 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 or is otherwise required upon the written advice of
     counsel to such Participating Broker-Dealer, give notice to the Company and
     allow the Company at its expense to undertake appropriate action to prevent
     disclosure of the Records deemed confidential;

          (o) comply with all applicable rules and regulations of the Commission
     and, as soon as reasonably practicable, make generally available to the
     Holders earnings statements of the Company covering at least 12 months
     satisfying the provisions of Section 11(a) of the Act and Rule 158
     thereunder (or any similar rule promulgated under the Act);

          (p) upon consummation of an Exchange Offer or a Private Exchange,
     obtain an opinion of counsel to the Company addressed to the Trustee for
     the benefit of all Holders of Registrable Securities participating in the
     Exchange Offer or the Private Exchange, as the case may be, and which
     includes an opinion that (i) the


                                       16

<PAGE>   50



     Company has duly authorized, executed and delivered the Exchange Notes and
     Private Exchange Notes and the Indenture, as the case may be, and (ii) each
     of the Exchange Notes or the Private Exchange Notes and the Indenture, as
     the case may be, constitute a legal, valid and binding obligation of the
     Company, enforceable against the Company in accordance with its respective
     terms (in each case, with customary exceptions);

          (q) 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 other Person as directed by the Company) in exchange for the
     Exchange Notes or the Private Exchange Notes, as the case may be, the
     Company shall mark, or cause to be marked, on such Registrable Securities
     delivered by such Holders that such Registrable Securities are being
     cancelled in exchange for the Exchange Notes or the Private Exchange Notes,
     as the case may be; in no event shall such Registrable Securities be marked
     as paid or otherwise satisfied;

          (r) 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 NASD;

          (s) use its best efforts to take all other steps necessary to effect
     the registration of the Registrable Securities covered by a Registration
     Statement contemplated hereby;

          (t) (A) in the case of the Exchange Offer Registration Statement (i)
     include in the Exchange Offer Registration Statement a section entitled
     "Plan of Distribution," which section shall be reasonably acceptable to the
     Initial Purchasers or another representative of the Participating
     Broker-Dealers, and which shall contain a summary statement of the
     positions taken or policies made by the staff of the Commission with
     respect to the potential "underwriter" status of any broker-dealer (a
     "PARTICIPATING BROKER-DEALER") that holds Registrable Securities acquired
     for its own account as a result of market-making activities or other
     trading activities and that will be the beneficial owner (as defined in
     Rule 13d-3 under the Exchange Act) of Exchange Notes to be received by such
     broker-dealer in the Exchange Offer, whether such positions or policies
     have been publicly disseminated by the staff of the Commission or such
     positions or policies, in the reasonable judgment of the Initial Purchasers
     or such other representative, represent the prevailing views of the staff
     of the Commission, including a statement that any such broker-dealer who
     receives Exchange Notes for Registrable Securities pursuant to the Exchange
     Offer may be deemed a statutory underwriter and must deliver a prospectus
     meeting the requirements of the Act in connection with any resale of such
     Exchange Notes, (ii) furnish to each Participating Broker-Dealer who has
     delivered to the Company the notice referred to in Section 3(e), without
     charge, as many copies of each Prospectus



                                       17

<PAGE>   51



     included in the Exchange Offer Registration Statement, including any
     preliminary prospectus, and any amendment or supplement thereto, as such
     Participating Broker-Dealer may reasonably request, (iii) subject to the
     last paragraph of this Section 3, hereby consent to the use of the
     Prospectus forming part of the Exchange Offer Registration Statement or any
     amendment or supplement thereto, by any Person subject to the prospectus
     delivery requirements of the Commission, including all Participating
     Broker-Dealers, in connection with the sale or transfer of the Exchange
     Notes covered by the Prospectus or any amendment or supplement thereto,
     (iv) use its best efforts to keep the Exchange Offer 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 Act for such period
     of time as such Persons must comply with such requirements in order to
     resell the Exchange Notes (PROVIDED, HOWEVER, that such period shall not be
     required to exceed 180 days, or such longer period if extended pursuant to
     the last sentence of this Section 3 (the "APPLICABLE PERIOD")), and (v)
     include in the transmittal letter or similar documentation to be executed
     by an exchange offeree all necessary information for such offeree to
     participate in the Exchange Offer;

          (B) in the case of any Exchange Offer Registration Statement, the
     Company agrees to deliver to the Initial Purchasers or to another
     representative of the Participating Broker-Dealers on behalf of the
     Participating Broker-Dealers upon consummation of the Exchange Offer (i) an
     opinion of counsel substantially in the form attached hereto as EXHIBIT A,
     (ii) an Officers' Certificate containing certifications substantially
     similar to those set forth in Section 8(d) of the Purchase Agreement and
     such additional certifications as are customarily delivered in a public
     offering of debt securities, and (iii) a comfort letter in customary form
     permitted by Statement of Auditing Standards No. 72 of the American
     Institute of Certified Public Accountants.

          The Company may require each seller of Registrable Securities as to 
which any registration is being effected to furnish to the Company such
information regarding such seller and the proposed distribution of such
Registrable Securities as the Company may from time to time reasonably request
in writing. The Company may exclude from such registration the Registrable
Securities of any seller who unreasonably fails to furnish such information
within a reasonable time after receiving such request.

          In the case of (i) a Shelf Registration Statement or (ii) 
Participating Broker-Dealers who have notified the Company that they will be
utilizing the Prospectus contained in the Exchange Offer Registration Statement
as provided in Section 3(t) hereof, are seeking to sell Exchange Notes and are
required to deliver copies of such Prospectus, each Holder agrees that, upon
receipt of any notice from the Company of the happening of any event of the kind
described in Section 3(e)(ii), 3(e)(iii), 3(e)(iv), 3(e)(v), 3(e)(vi) or
3(e)(vii) hereof, such Holder will forthwith discontinue disposition of
Registrable Securities


                                       18
<PAGE>   52



pursuant to a Registration Statement until such Holder's receipt of the copies
of the supplemented or amended Prospectus contemplated by Section 3(i) hereof or
until it is advised in writing by the Company that the use of the applicable
Prospectus may be resumed, and, if so directed by the Company, such Holder will
deliver to the Company (at the Company's expense) all copies in such Holder's
possession, other than permanent file copies then in such Holder's possession,
of the Prospectus covering such Registrable Securities or Exchange Notes, as the
case may be, current at the time of receipt of such notice. If the Company
shall give any such notice to suspend the disposition of Registrable Securities
or Exchange Notes, as the case may be, pursuant to a Registration Statement, the
Company shall use its best efforts to file and have declared effective (if an
amendment) as soon as practicable an amendment or supplement to the Registration
Statement and shall extend the period during which such Registration Statement
shall be maintained effective pursuant to this Agreement by the number of days
in the period from and including the date of the giving of such notice to and
including the date when the Company shall have made available to the Holders
copies of the supplemented or amended Prospectus necessary to resume such
dispositions or shall have advised the Holders in writing that the use of the
applicable Prospectus may be resumed.

          4. INDEMNIFICATION AND CONTRIBUTION. (a) The Company shall indemnify 
and hold harmless the Initial Purchasers, each Holder, each Participating
Broker-Dealer, each underwriter who participates in an offering of Registrable
Securities, each of their respective affiliates, each Person, if any, who
controls any of such parties within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, and each of their respective directors,
officers, partners, employees, representatives and agents, to the fullest extent
lawful as follows'

          (i) from and against any and all loss, liability, claim, damage and
     expense whatsoever, joint or several, as incurred, arising out of any
     untrue statement or alleged untrue statement of a material fact contained
     in any Registration Statement or any amendment thereto pursuant to which
     the offer and sale of the Registrable Securities or Exchange Notes were
     registered under the Act including all documents incorporated therein by
     reference, or the omission or alleged omission therefrom of a material fact
     required to be stated therein or necessary to make the statements thereto
     not misleading, or arising out of any untrue statement or alleged untrue
     statement of a material fact contained in any Prospectus or any amendment
     or supplement thereto, or the omission or alleged omission therefrom of a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

          (ii) from and against any and all loss, liability, claim, damage and
     expense whatsoever, joint or several, to the extent of the aggregate amount
     paid in settlement of any litigation, or any investigation or proceeding by
     any court or governmental agency or body, whether commenced or threatened,
     or any claim whatsoever based upon any such untrue statement or omission,
     or any such alleged untrue statement or



                                       19

<PAGE>   53



     omission, if and only if such settlement is effected with the prior written
     consent of the Company; and

          (iii) from and against any and all expenses whatsoever (including
     reasonable fees and disbursements of counsel chosen by the Initial
     Purchasers, Holder, Participating Broker-Dealer or underwriter (except to
     the extent otherwise expressly provided in Section 4(c) hereof)), as
     incurred, reasonably incurred in investigating, preparing for or defending
     against any litigation, or any investigation or proceeding by any court or
     governmental agency or body, whether commenced or threatened, or any other
     claim whatsoever based upon any such untrue statement or omission, or any
     such alleged untrue statement or omission, to the extent that any such
     expense is not paid under subparagraph (i) or (ii) of this Section 4(a);

PROVIDED, HOWEVER, that this indemnity does not apply to any loss, liability,
claim, damage or expense to the extent arising out of an untrue statement or
omission or alleged untrue statement or omission (i) made solely in reliance
upon and in conformity with written information furnished to the Company by the
Initial Purchasers, such Holder, such Participating Broker-Dealer or any
underwriter in writing expressly for use in the Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto) or
(ii) contained in any preliminary prospectus or any Prospectus if the Initial
Purchasers, such Holder, such Participating Broker-Dealer or such underwriter
failed to send or deliver a copy of the Prospectus (as then amended or
supplemented if the Company shall have timely furnished any amendments or
supplements thereto) to the Person asserting such losses, liabilities, claims or
damages on or prior to the delivery of written confirmation of any sale of
securities covered thereby to such Person in any case where such delivery is
required by the Act and such Prospectus (as so amended or supplemented) would
have corrected such untrue statement or omission and the delivery thereof would
have eliminated such losses, claims, damages or liabilities. Any amounts
advanced by the Company to an indemnified party pursuant to this Section 4 as a
result of such losses shall be returned to the Company if it shall be determined
by a court that such indemnified party was not entitled to indemnification by
the Company.

          (b) Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, the Initial Purchasers, each underwriter who
participates in an offering of Registrable Securities and the other selling
Holders and each of their respective directors, officers (including each officer
of the Company who signed the Registration Statement), employees,
representatives and agents, and each Person, if any, who controls the Company,
the Initial Purchasers, any underwriter or any other selling Holder within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and
against any and all loss, liability, claim, damage and expense whatsoever
described in the indemnity contained in Section 4(a) hereof, as reasonably
incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto)
solely in reliance upon and in conformity with written information furnished to
the


                                       20

<PAGE>   54



Company by such selling Holder expressly for use in the Registration Statement
(or any amendment thereto) or any such Prospectus (or any amendment or
supplement thereto); PROVIDED, HOWEVER, that, in the case of a Shelf
Registration Statement, no such Holder shall be liable for any claims hereunder
in excess of the amount of net proceeds received by such Holder from the sale of
Registrable Securities pursuant to such Shelf Registration Statement.

          (c) Each indemnified party shall give prompt notice to each 
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, enclosing a copy of all papers properly
served on such indemnified party (but failure to notify an indemnifying party
shall not relieve such indemnifying party from any liability hereunder to the
extent it is not materially prejudiced as a result thereof and in any event
shall not relieve it from any liability which it may have other than on account
of this indemnity agreement). An indemnifying party may participate, at its own
expense, in the defense of any such action. If an indemnifying party so elects
within a reasonable time after receipt of such notice, such indemnifying party,
jointly with any other indemnifying party, may assume the defense of such action
with counsel chosen by it and reasonably satisfactory to the indemnified parties
defendant in such action; PROVIDED, HOWEVER, that if any such indemnified party
reasonably determines, upon written advice of counsel, that there may be legal
defenses available to such indemnified party which are different from or in
addition to those available to such indemnifying party or that representation of
such indemnifying party and any indemnified party by the same counsel would
present a conflict of interest, then one additional counsel in each jurisdiction
for all indemnified parties having consistent interests and such different or
additional defenses or subject to such conflict shall be entitled to conduct the
defense of such indemnified parties with the fees and expenses of such counsel
to be borne by the indemnifying party or parties. If an indemnifying party
assumes the defense of an action in accordance with and as permitted by the
provisions of this Section 4(c), such indemnifying party shall not be liable for
any fees and expenses of counsel for the indemnified parties incurred thereafter
in connection with such action (except to the extent set forth in the proviso
contained in the immediately preceding sentence). In no event shall the
indemnifying party or parties be liable for the fees and expenses of more than
one counsel for all indemnified parties in connection with any one action, or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances. No indemnifying party shall,
without the prior written consent of the indemnified parties, which consent
shall not be unreasonably withheld, settle or compromise or consent to the entry
of any judgment with respect to any litigation, or any investigation or
proceeding by any governmental agency or body, commenced or threatened, or any
claim whatsoever in respect of which indemnification or contribution could be
sought under this Section 4, unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and does not
include a statement as to or an admission of fault, culpability or a failure to
act by or on behalf of any indemnified party.

          (d) Notwithstanding any payment or payments made by the Company 
hereunder, the Company hereby expressly waives subrogation to, and agrees that
it shall not


                                       21

<PAGE>   55



be entitled to be subrogated to, any of the rights of any indemnified party
against the Company or any other right of offset held by any indemnified party
for the payment of any amounts owed to any indemnified party pursuant to this
Section 4; PROVIDED, HOWEVER, that if any of the foregoing provisions of this
paragraph are held to be contrary to applicable law or unenforceable by a court
of competent jurisdiction, the Company hereby expressly agrees that any right of
subrogation or contribution that the Company may have as a result of such
applicable law or unenforceability, as the case may be, shall be subordinate in
right of payment to the payment in full in cash of all amounts owed to any
indemnified party pursuant to this Section 4.

          (e) If the indemnification provided for in this Section 4 is for any 
reason unavailable to or insufficient to hold harmless an indemnified party in
respect of any losses, liabilities, claims, damages or expenses referred to
herein, then each indemnifying party shall contribute to the aggregate amount of
such losses, liabilities, claims, damages and expenses incurred by such
indemnified party, as incurred, (i) in such proportion as is appropriate to
reflect the relative benefits received by the indemnifying party or parties on
the one hand and the indemnified party or parties on the other hand from the
offering of the Notes pursuant to the Purchase Agreement, or (ii) if the
allocation provided by clause (i) 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 indemnifying party or
parties on the one hand and of the indemnified party or parties on the other
hand in connection with the statements or omissions which resulted in such
losses, liabilities, claims, damages or expenses, 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 hand in connection with the offering of the
Notes pursuant to the Purchase Agreement shall be deemed to be in the same
respective proportions as the total net proceeds from the offering of the Notes
pursuant to the Purchase Agreement (before deducting expenses) received by the
Company and the total discount received by the Initial Purchasers bear to the
aggregate initial offering price of the Notes.

          The relative fault of the Company on the one hand and the Holders on
the other hand shall be determined by reference to, among other things, whether
any such untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by the
Company or by the Holders, and the respective parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

          The Company and the Holders agree that it would not be just and 
equitable if contribution pursuant to this Section 4 were determined by PRO RATA
allocation (even if the Holders were treated as one entity for such purpose) or
by any other method of allocation which does not take account of the equitable
considerations referred to above in this Section 4(e). The aggregate amount of
losses, liabilities, claims, damages and expenses incurred by an indemnified
party and referred to above in this Section 4(e) shall be deemed to include


                                       22

<PAGE>   56



any legal or other expenses reasonably incurred by such indemnified party in
investigating, preparing for or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any untrue or alleged untrue
statement or omission or alleged omission referred to in Section 4(a)(i).

          Notwithstanding the provisions of this Section 4(e), no Initial 
Purchaser shall be required to contribute any amount in excess of the amount by
which the total discount received by such Initial Purchaser in respect of the
purchase price of the Notes purchased by it from the Company exceeds the amount
of any damages which the Initial Purchasers have 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 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          For purposes of this Section 4(e), each person, if any, who controls
an Initial Purchaser, a Holder, a Participating Broker-Dealer, an underwriter
who participates in an offering of Registrable Securities, or the affiliates of
any of them, within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act shall have the same rights to contribution as the Initial
Purchasers, and each director, officer (including each officer of the Company
who signed the Registration Statement), partner, employee, representative and
agent of the Company, the Initial Purchasers, each Holder, each Participating
Broker-Dealer, and each underwriter who participates in an offering of
Registrable Securities and each person, if any, who controls the Company within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall
have the same rights to contribution as the Company.

          5. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Holder 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
customary underwriting arrangements approved by the Holders of a majority in
aggregate principal amount of the Registrable Securities included in such
offering and (b) completes and executes all reasonable questionnaires, powers of
attorney, indemnities, underwriting agreements, lock-up letters and other
documents reasonably required in connection with such underwriting arrangements.

          6. SELECTION OF UNDERWRITERS. In any underwritten offering, the 
underwriter or underwriters and manager or managers that will administer the
offering will be selected by the Holders of a majority in aggregate principal
amount of the Registrable Securities included in such offering; PROVIDED,
HOWEVER, that such underwriters and managers must be reasonably satisfactory to
the Company.

                                                                       Exhibit A
                                                                       ---------

                           Form of Opinion of Counsel
                           --------------------------

          1. Each of the Exchange Offer Registration Statement and the 
Prospectus (other than the financial statements, notes or schedules thereto and
other financial and statistical data and supplemental schedules included or
referred to therein or omitted therefrom and the Form T-l, as to which such
counsel need express no opinion), complies as to form in all material respects
with the applicable requirements of the Act and the applicable rules and
regulations promulgated under the Act.

          2. In the course of such counsel's review and discussion of the 
contents of the Exchange Offer Registration Statement and the Prospectus with
certain officers and other representatives of the Company and representatives of
the independent certified public accountants of the Company, but without
independent check or verification or responsibility for the accuracy,
completeness or fairness of the statements contained therein, on the basis of
the foregoing (relying as to materiality to a large extent upon representations
and opinions of officers and other representatives of the Company), no facts
have come to such counsel's attention which cause such counsel to believe that
the Exchange Offer Registration Statement (other than the financial statements,
notes and schedules thereto and other financial and statistical information
contained or referred to therein and the Form T-l, as to which such counsel need
express no belief), at the time the Exchange Offer Registration Statement became
effective, contained an untrue statement of a material fact or omitted to state
a material fact required to be stated therein or necessary to make the
statements contained therein not misleading, or that the Prospectus (other than
the financial statements, notes and schedules thereto and other financial and
statistical information contained or referred to therein, as to which such
counsel need express no belief) contains any untrue statement of a material fact
or omits to state a material fact necessary to make the statements contained
therein, in the light of the circumstances under which they were made, not
misleading.

                                  EXHIBIT C-1

                         Form of Opinion of Ropes & Gray

          1. The Company is duly incorporated and is validly existing as a
corporation in good standing under the laws of the State of Delaware and is duly
qualified and in good standing as a foreign corporation authorized to do
business in each jurisdiction in which the nature of its business or its
ownership or leasing of property requires such qualification, except where the
failure to be so qualified or in good standing would not have a material adverse
effect on the Company and its subsidiaries taken as a whole. The Company has all
requisite corporate authority to carry on its business as it is currently being
conducted and to own, lease and operate its properties as described in the
Offering Memorandum. The Company has all requisite corporate authority to
execute, deliver and perform its obligations under the Purchase Agreement and
each of the other Operative Documents to which it is a party and to consummate

          2. The Purchase Agreement has been duly authorized, executed and 
delivered by the Company.

          3. The Indenture has been duly authorized, executed and delivered by 
the Company and, assuming the due authorization, execution and delivery thereof
by the Trustee, is a legal, valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms, except to the
extent that (i) the enforceability thereof may be limited by bankruptcy,
insolvency, fraudulent conveyance, reorganization or other similar laws relating
to or affecting enforcement of creditors' rights generally and (ii) rights of
acceleration and the availability of equitable remedies may be limited by
general principles of equity.

          4. The Registration Rights Agreement has been duly authorized,

other similar laws relating to or affecting enforcement of creditors' rights
generally, (ii) rights of acceleration and the availability of equitable
remedies may be limited by general principles of equity and (iii) rights of
indemnity or contribution thereunder may be limited by federal or state

Company for issuance and sale to the Initial Purchasers pursuant to the Purchase
Agreement and, when issued and authenticated in accordance with the terms of the
Indenture and delivered against payment therefor in accordance with the terms
hereof and thereof, will be legal, valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms and entitled to
the benefits of the Indenture, subject to applicable bankruptcy, insolvency,
fraudulent conveyance, reorganization or


                                      C-l-1

entitled to the benefits of the Indenture, subject to applicable bankruptcy,
insolvency, fraudulent conveyance, reorganization or similar laws relating to or
affecting the rights of creditors generally, and subject to limitations on

          7. When the Notes are issued and delivered pursuant to the Purchase
Agreement, no Note will be of the same class (within the meaning of Rule 144A
under the Act) as securities of the Company that are listed on a national
securities exchange registered under Section 6 of the Exchange Act or that are
quoted in a United States automated inter-dealer quotation system.

          8. The execution and delivery by the Company of the Purchase Agreement
and of the other Operative Documents, the performance by the Company of its
agreements pursuant to the Purchase Agreement and the other Operative Documents
and the consummation of the transactions contemplated hereby and thereby
(including, without limitation, the issuance, sale and delivery of the Notes by
the Company) do not (i) conflict with or result in a breach or violation 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 of or require the prepayment of any obligation of the Company, or
require any consent, or result in the creation or imposition of any lien, charge
or encumbrance upon any property or assets of the Company pursuant to, the terms
of any contract, agreement or document identified as an exhibit to the Company's
Annual Report on Form 10-K, (ii) violate or conflict with any provisions of the
certificate of incorporation or bylaws of the Company or (iii) to such counsel's
knowledge (assuming, solely for purposes of the opinion set forth in this clause

provisions of federal and state securities laws, as to which such counsel need
not express an opinion), violate or conflict with any judgment, decree, order,
statute, rule or regulation of any court or any public, governmental or
regulatory agency or body having jurisdiction over the Company or any of its
respective properties or assets, except for such breaches, violations or
conflicts which, individually or in the aggregate, do not and would not
reasonably be expected to have a material adverse effect on the business,
properties, assets, liabilities (contingent or otherwise), earnings, operations,
conditions (financial and otherwise) or results of operations of the Company and
its subsidiaries taken as a whole. Assuming compliance with applicable state
securities and Blue Sky laws, as to which such counsel need express no opinion,
and except for the filing of a registration statement under the Act and
qualification of the Indenture under the Trust Indenture Act, in each case as
contemplated by the Registration Rights Agreement, no consent, approval,
authorization or order of, or filing, registration, qualification, license or
permit of or with any court or governmental agency, body or administrative
agency is required for (1) the execution, delivery and performance by the
Company of the Purchase Agreement or any of the other Operative Documents to
which it is a party; or (2) the issuance and sale of the Notes, except such as
have been obtained and made or have been disclosed in the Offering Memorandum.

<PAGE>   62



          9. Neither the Company nor any subsidiary of the Company is and upon
consummation of the transactions contemplated in the Purchase Agreement none of
the Company or any subsidiary of the Company will be, subject to registration as
an "investment company" within the meaning of the Investment Company Act of 1940
and the rules and regulations promulgated thereunder.

         10. Assuming (i) the accuracy of, and compliance with, the 
representations, warranties, covenants and agreements of the Company and the
Initial Purchasers contained in the Purchase Agreement, (ii) the accuracy of,
and compliance with, the representations, warranties, covenants and agreements
of each of the persons to whom the Initial Purchasers initially resells or
otherwise transfers the Notes, as specified in the Offering Memorandum, and
(iii) the compliance by the Initial Purchasers with the offering and transfer
procedures and restrictions described in the Offering Memorandum, it is not
necessary in connection with the offer, sale and delivery of the Notes to the
Initial Purchasers or in connection with the initial resale of the Notes by the
Initial Purchasers in the manner contemplated by the Purchase Agreement and the
Offering Memorandum to register the sale of the Notes to the Initial Purchasers
or the Exempt Resales under the 1933 Act, it being understood that such counsel
need not express any opinion as to any subsequent reoffers, resales or other
transfers of any Notes, or to qualify the Indenture under the Trust Indenture
Act of 1939, as amended.

         11. None of the execution, delivery and performance of the Purchase
Agreement, the issuance and sale of the Notes, the application of the proceeds

Regulation G, T, U or X promulgated by the Board of Governors of the Federal
Reserve System.

         12. The Purchase Agreement, the Indenture, the Notes and the 
Registration Rights Agreement conform in all material respects as to the
descriptions thereof contained in the Offering Memorandum.

the basis of information that such counsel has gained in the course of its
representation of the Company in connection with its preparation of the Offering
Memorandum and its participation in the discussions referred to above, such
counsel has no reason to believe that, as of the date of the Offering Memorandum
or the Closing Date, the Offering Memorandum contained or contains any untrue
statement of a material fact or omitted or omits 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. Such

Company for issuance and sale to the Initial Purchasers pursuant to the Purchase
Agreement and, when issued and authenticated in accordance with the terms of the

hereof and thereof, will be legal, valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms and entitled to
the benefits of the Indenture, subject to applicable bankruptcy, insolvency,
fraudulent conveyance, reorganization or similar laws relating to or affecting
the rights of creditors generally, and subject to limitations on rights of
acceleration and the availability of equitable remedies under general principles
of equity.

and of the other Operative Documents, the performance by the Company of its
agreements pursuant to the Purchase Agreement and the other Operative Documents
and the consummation of the transactions contemplated hereby and thereby
(including, without limitation, the issuance, sale and delivery of the Notes by
the Company) do not (i) conflict with or result in a breach or violation 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 of or require the prepayment of any obligation of the Company or any
Significant Subsidiary, or require any consent, or result in the creation or

such counsel's knowledge (assuming, solely for purposes of the opinion set forth
in this clause (iii), compliance with state securities or Blue Sky laws and the
antifraud provisions of federal and state securities laws, as to which such
counsel need not express an opinion), violate or conflict with any judgment,
decree, order, statute, rule or regulation of any court or any public,
governmental or regulatory agency or body having jurisdiction over the Company
or any Significant Subsidiary or any of their respective properties or assets,
except for such breaches, violations or conflicts which, individually or in the
aggregate, do not and would not reasonably be expected to have a material
adverse effect on the business, properties, assets, liabilities (contingent or
otherwise), earnings, operations, conditions (financial and otherwise) or
results of operations of the Company and its subsidiaries taken as a whole.
Assuming compliance with applicable state securities and Blue Sky laws, as to
which such counsel need express no opinion, and



                                      C-2-2

except for the filing of a registration statement under the Act and
qualification of the Indenture under the Trust Indenture Act, in each case as
contemplated by the Registration Rights Agreement, no consent, approval,

before or by any public, regulatory or governmental agency or body pending or
threatened against, or involving the properties or business of, the Company or
relating to the issuance or sale of the Notes, which would have a material
adverse effect on the ability of the Company to perform its obligations under
any Operative Document or to consummate the transactions contemplated by the
Offering Memorandum or the Operative Documents.

          11. Except as set forth in the Registration Rights Agreement, to such
counsel's knowledge, there are no holders of securities of the Company or any of
its subsidiaries who, by reason of the execution by the Company of the Purchase
Agreement or any other Operative Document or the consummation by the Company and

or demand that the Company or any of its subsidiaries register under the Act or
analogous foreign laws and regulations securities held by them.

Registration Rights Agreement conform in all material respects as to the
descriptions thereof contained in the Offering Memorandum.

certain discussions with representatives of and counsel to the Initial
Purchasers, and representatives of the Company and its independent accountants,
in which the business and affairs of the Company and the contents of the

responsibility for the legal affairs of the Company, the Company is represented
by separate litigation counsel with respect to litigation matters, and such
counsel has not reviewed individual litigation files of the Company or consulted

of such counsel's duties as the Company's general counsel, such counsel does not
know of any legal or governmental proceeding to which the Company or any of its
subsidiaries is a party or to which any of its property is subject required to

contract or other document of a character required to be described in the
Offering Memorandum which is not so described; (iv) based on such information

                                    THE NOTES
                                    ---------

     SECTION 2.01 FORM AND DATING. The Original Notes and the Trustee's
certificate of authentication relating thereto shall be substantially in the
form of Exhibit A hereto, with such appropriate insertions, substitutions and
other variations as are required or permitted by this Indenture. The Exchange
Notes and the Trustee's certificate of authentication relating thereto shall be
substantially in the form of Exhibit A hereto, with such appropriate insertions,
substitutions and other variations as are required or permitted by this
Indenture; provided, that Exchange Notes issued in the Exchange Offer shall not
bear the legend set forth in Exhibit A hereto as indicated by footnote 2;
provided, further, that Exchange Notes issued in either the Exchange Offer or
the Private Exchange shall not contain any reference to Liquidated Damages and
shall not include paragraph 19 of Exhibit A hereto. The Notes may have
notations, legends or endorsements required by this Indenture, law, stock

     The terms and provisions contained in the Notes, annexed hereto as Exhibit
A, shall constitute, and are hereby expressly made, a part of this Indenture. To
the extent applicable, the Company, by its execution and delivery of this
Indenture, expressly agrees to such terms and provisions and to be bound
thereby.

     The Original Notes initially will be issued in global form, substantially
in the form of Exhibit A attached hereto (including the text set forth in
footnote 1 thereto and the additional schedule referred to therein) and may be
issued in definitive form, substantially in the form of Exhibit A hereto (not
including the text set forth in footnote 1 thereto and the additional schedule
referred to therein). The Original Notes initially will be deposited with the
Trustee, as Note Custodian. The Global Notes initially shall be registered in
the name of the Depository or the nominee of the Depository. A Global Note shall
represent such of the outstanding Notes as shall be specified therein and shall
provide that it shall represent the aggregate amount of outstanding Notes from
time to time endorsed thereon and that the aggregate amount of outstanding Notes
represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges and redemptions. Any endorsement of a Global
Note to reflect the amount of any increase or decrease in the amount of
outstanding Notes represented thereby shall be made by the Trustee, as Note
Custodian, in accordance with instructions given by the Holder thereof as
required by Section 2.06 hereof.

     To the extent permitted by the terms of the 9-7/8% Notes and the indenture
governing the 9-7/8% Notes (the "9-7/8% Indenture"), all obligations owing under
this Indenture and the Notes, including interest accruing after the occurrence
of an event described in clause (5) or (6) of Section 6.01 of the Indenture,
shall constitute "Specified Senior Indebtedness" or similarly- designated
indebtedness under the 9-7/8% Notes and the 9-7/8% Indenture and under any other
existing or future subordinated indebtedness of the Company.

     SECTION 2.02 EXECUTION AND AUTHENTICATION. The Notes shall be executed on
behalf of the Company by its Chairman of the Board, one of its Vice Chairmen,
its President or one of its Vice Presidents, under its corporate seal reproduced
thereon attested by its Secretary or one of its Assistant Secretaries. The
signature of any such officer on the Notes may be manual or facsimile.

     If an Officer of the Company whose signature is on a Note no longer holds
that office at the time the Note is authenticated, the Note shall nevertheless
be valid.

     Only such Notes as shall bear thereon a certificate of authentication
substantially in the form set forth in Exhibit A hereto, manually executed by
the Trustee, shall be entitled to the benefits of this Indenture or be valid or
obligatory for any purpose. Such certificate of authentication executed by the
Trustee upon any Note executed by the Company shall be conclusive evidence that
the Note so authenticated has been duly authenticated and made available for
delivery hereunder.


                                       20

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Notes executed by the Company to the Trustee
for authentication, together with a request for the authentication and delivery
of such Notes signed by an Officer of the Company, and the Trustee, in
accordance with such request, shall authenticate and deliver such Notes as
provided in this Indenture.

     The Trustee shall authenticate (i) Original Notes for original issue in the
aggregate principal amount not to exceed $175,000,000, and (ii) Exchange Notes
issued, either (x) in the Exchange Offer for the Original Notes pursuant to the
Exchange Offer Registration Statement filed with the Commission from time to
time, for issue only in exchange for a like principal amount of Original Notes
or (y) in the Private Exchange, for issue only in exchange for a like principal
amount of Original Notes, in each case, upon written order of the Company in the
form of an Officers' Certificate. Such Officers' Certificate shall specify the
amount of Notes to be authenticated and the date on which the Notes are to be
authenticated, whether the Notes are to be Original Notes or Exchange Notes and
whether the Notes are to be Definitive Notes or Global Notes. Except as
contemplated by Section 2.07 hereof, the aggregate principal amount of Notes
outstanding at any time may not exceed $175,000,000. Notwithstanding the
foregoing, all Notes issued under this Indenture shall vote and consent together
on all matter as one class and no series of Notes will have the right to vote or
consent as a separate class on any matter.

     The Notes shall be issuable in fully registered form only, without coupons,
in denominations of $1,000 and any integral multiple thereof.

     The Trustee shall act as the initial authenticating agent. Thereafter, the
Trustee may appoint an authenticating agent reasonably acceptable to the Company
to authenticate the Notes. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate of the Company. The Trustee shall not be liable for any act or
failure to act of the authenticating agent to perform any duty either required
herein or authorized herein to be performed by such person in accordance with
this Indenture. Each authenticating agent shall be acceptable to the Company and
otherwise comply in all respects with the eligibility requirements of the
Trustee contained in this Indenture.

     SECTION 2.03 REGISTRAR AND PAYING AGENT. The Company shall maintain or
cause to be maintained an office or agency where (a) Notes may be presented for
registration of transfer or for exchange ("Registrar"), (b) Notes may be
presented or surrendered for purchase or payment ("Paying Agent") and (c)
notices and demands to or upon the Company in respect of the Notes may be
served. The Registrar shall keep a register of the Notes and of their transfer
and exchange. The Company may appoint one or more co-registrars and one or more
additional paying agents. The term "Registrar" includes any co-registrar and the
term "Paying Agent" includes any additional paying agents. The Company may
change any Paying Agent or Registrar without notice to any Holder. The Company
shall notify the Trustee of the name and address of


                                       21

<PAGE>   27


any Agent not a party to this Indenture. If the Company fails to appoint or
maintain another entity as Registrar or Paying Agent, the Trustee shall act as
such and shall be entitled to appropriate compensation in accordance with
Section 7.07 hereof. The Company or any of its Subsidiaries may act as Paying
Agent or Registrar.

     The Company shall enter into an appropriate agency agreement with any Agent
not a party to this Indenture, which shall incorporate the provisions of the
TIA. The agreement shall implement the provisions of this Indenture that relate
to such Agent. The Company initially appoints The Depository Trust Company
("DTC") to act as Depository with respect to the Global Notes.

     The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and agent for service of notices and demands in connection with the
Notes.

     SECTION 2.04 PAYING AGENT TO HOLD MONEY IN TRUST. Except as otherwise
provided herein, prior to each due date of the principal, premium, if any, and
interest on any Note, the Company shall deposit with the Paying Agent a sum of
money sufficient to pay such principal, premium, if any, and interest or
Liquidated Damages so becoming due. The Company shall require each Paying Agent
(other than the Trustee or the Company) to agree in writing that such Paying
Agent shall hold in trust for the benefit of the Holders or the Trustee all
money held by the Paying Agent for the payment of principal, premium, if any,
and interest on the Notes (whether such money has been paid to it by the Company
or any other obligor on the Notes) and shall notify the Trustee of any default
by the Company (or any other obligor on the Notes) in making any such payment.
At any time during the continuance of any such default, the Paying Agent shall,
upon the request of the Trustee, forthwith pay to the Trustee all money so held
in trust and account for any money disbursed to it. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and to account
for any money disbursed by it. Upon doing so, the Paying Agent shall have no
further liability for the money so paid over to the Trustee. If the Company, a
Subsidiary or an Affiliate of either of them acts as Paying Agent, it shall
segregate the money held by it as Paying Agent and hold it as a separate trust
fund.

     SECTION 2.05 HOLDER 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 Holders. If the Trustee is not the Registrar, the Company shall
cause to be furnished to the Trustee on or before each interest payment date and
at such other times as the Trustee may request in writing, within five Business
Days of such request, a list in such form as the Trustee may reasonably require
of the names and addresses of Holders.

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

          (1) TRANSFER AND EXCHANGE OF DEFINITIVE NOTES. When Definitive Notes
     are presented to the Registrar with the request to register the transfer of
     the Definitive Notes, or to exchange such Definitive Notes for an equal
     principal amount of Definitive Notes of


                                       22

<PAGE>   28



     other authorized denominations, the Registrar shall register the transfer
     or make the exchange as requested if its requirements for such transactions
     are met; provided, however, that the Definitive Notes presented or
     surrendered for registration of transfer or exchange:

                    (a) shall be duly endorsed or accompanied by a written
               instrument of transfer in form satisfactory to the Trustee and
               the Registrar duly executed by the Holder thereof or by an
               attorney who is duly authorized in writing to act on behalf of
               the Holder; and

                    (b) shall, in the case of a Transfer Restricted Security, be
               accompanied by the following additional information and
               documents, as applicable:

                    from such Holder to that effect (in substantially the form
                    of Exhibit B hereto); or

                         (ii) if such Transfer Restricted Securities are being
                    transferred (1) to a "qualified institutional buyer" (as
                    defined in Rule 144A under the Securities Act) in a
                    transaction meeting the requirements of Rule 144A under the
                    Securities Act or (2) pursuant to an exemption from
                    registration in a transaction meeting the requirements of

                    Counsel if the Company so requests) or (3) pursuant to an
                    effective registration statement under the Securities Act, a

                    the Securities Act pursuant to a private placement exemption
                    from the registration requirements of the Securities Act

                    requests), a certification to that effect from such Holder
                    (in substantially the form of Exhibit B hereto) and a
                    certification from the applicable transferee (in
                    substantially the form of Exhibit C hereto);

                         (iv) if such Transfer Restricted Securities are being
                    transferred outside the U.S. to a foreign person pursuant to
                    an exemption from registration in a transaction meeting the
                    requirements of Regulation S under the Securities Act (based
                    on an Opinion of Counsel if the Company so requests),

                    transferred in reliance on another exemption from the
                    registration requirements of the Securities Act (based upon

                    certification to that effect from such Holder (in
                    substantially the form of Exhibit B hereto).

              (2) TRANSFER OF A DEFINITIVE NOTE FOR A BENEFICIAL INTEREST IN A
     GLOBAL NOTE. A Definitive Note may not be exchanged for a beneficial
     interest in a Global Note except upon satisfaction of the requirements set

               obtain a beneficial interest in a Global Note, a certification
               from such Holder to that effect (in substantially the form of
               Exhibit B hereto); provided that such Holder provides a
               certification that such Holder is otherwise permitted to hold a
               beneficial interest in a Global Note;

               registration requirements of the Securities Act (based upon an
               Opinion of Counsel if the Company so requests), provided that the
               Trustee receives a certification from such transferee (in
               substantially the form of Exhibit C hereto), or (C) to a foreign
               person outside the U.S. pursuant to an exemption from

               with the standing instructions and procedures existing between
               the Depository and the Note Custodian, the aggregate principal
               amount of Notes represented by the Global Note to be increased;

then the Trustee shall cancel such Definitive Note in accordance with Section
2.01 hereof and cause, or direct the Note Custodian to cause, in accordance with
the standing instructions and


                                       24

and, upon receipt of an authentication order in accordance with Section 2.02
hereof, and an agreement with the Depository in customary form and substance
acceptable to the Trustee, the Trustee shall authenticate a new Global Note in
the appropriate principal amount.

               (3) TRANSFER AND EXCHANGE OF GLOBAL NOTES. The transfer and
          exchange of Global Notes or beneficial interests therein shall be

          restrictions on transfer comparable to those set forth herein to the
          extent required by the Securities Act; provided, however, that neither
          the Trustee nor the Registrar shall have any obligation to monitor or
          restrict the transfer of any beneficial interest in the Notes
          transferable through the book-entry facilities of the Depository.

               (4) TRANSFER OF A BENEFICIAL INTEREST IN A GLOBAL NOTE FOR A

               may upon request exchange such beneficial interest for a
               Definitive Note. Upon receipt by the Trustee of written
               instructions or such other form of instructions as is customary
               for the Depository from the Depository or its nominee on behalf
               of any Person having a beneficial interest in a Global Note, and,

                      being the beneficial owner, a certification from such
                      Person to that effect (in substantially the form of
                      Exhibit B hereto); or

                               (ii) if such beneficial interest is being
                      transferred (1) to a "qualified institutional buyer" (as

                      of Counsel if the Company so requests) or (3) pursuant to
                      an effective registration statement under the Securities
                      Act, a certification to that effect from the transferor
                      (in substantially the form of Exhibit B hereto); or

                               (iii) if such beneficial interest is being
                      transferred to an institutional "accredited investor,"
                      within the meaning of Rule 501(a)(1), (2), (3) or (7)
                      under the Securities Act pursuant to a private placement
                      exemption from


                                       25

<PAGE>   31



                      the registration requirements of the Securities Act (based
                      upon an Opinion of Counsel if the Company so requests), a
                      certification to that effect from such transferor (in
                      substantially the form of Exhibit B hereto) and a
                      certification from the applicable transferee (in
                      substantially the form of Exhibit C hereto); or

                               (iv) if such beneficial interest is being
                      transferred outside the U.S. to a foreign person pursuant
                      to an exemption from registration in a transaction meeting
                      the requirements of Regulation S under the Securities Act
                      (based upon an Opinion of Counsel if the Company so
                      requests), certifications to that effect from such
                      transferor (in substantially the form of Exhibits B and D
                      hereto); and

                               (v) if such beneficial interest is being
                      transferred in reliance on another exemption from the
                      registration requirements of the Securities Act (based
                      upon an Opinion of Counsel if the Company so requests), a
                      certification to that effect from such transferor (in
                      substantially the form of Exhibits B and D hereto);

then the Trustee or the Note Custodian, at the direction of the Trustee, shall,
in accordance with the standing instructions and procedures existing between the
Depository and the Note Custodian, cause the aggregate principal amount of
Global Notes to be reduced accordingly and, following such reduction, the
Company shall execute and, upon receipt of an authentication order in accordance
with Section 2.02 hereof, the Trustee shall authenticate and deliver to the
transferee a Definitive Note in the appropriate principal amount.

                    (b) Definitive Notes issued in exchange for a beneficial
               interest in a Global Note pursuant to this Section 2.06(4) shall
               be registered in such names and in such authorized denominations
               as the Depository, pursuant to instructions from its direct or
               indirect participants or otherwise, shall instruct the Trustee.
               The Trustee shall deliver such Definitive Notes to or as directed
               by the Persons in whose names such Notes are so registered.

               (5) RESTRICTIONS ON TRANSFER AND EXCHANGE OF GLOBAL NOTES.
          Notwithstanding any other provisions of this Indenture (other than the
          provisions set forth in subsection (6) of this Section 2.06), a Global

               or an effective registration statement under the Securities Act:

                    Global Note have been or are concurrently being sold or
                    transferred pursuant to Rule 144 under the Securities Act or
                    pursuant to an effective registration statement under the
                    Securities Act, but such Transfer Restricted Securities
                    shall continue to be subject to the provisions of Section
                    2.06(3) hereof; provided, however, that with respect to any
                    request for an exchange of a Transfer Restricted Security
                    that is represented by a Global Note for a Definitive Note
                    that does not bear a legend set forth in clause (a) above,
                    which request is made in reliance upon Rule 144, the Holder
                    thereof shall certify in writing to the Registrar that such
                    request is being made pursuant to Rule 144 (such
                    certification to be substantially in the form of Exhibit B
                    hereto).

                    (d) Notwithstanding the foregoing, upon consummation of the
               Exchange Offer, the Company shall issue and, upon receipt of an
               authentication order in accordance with Section 2.02 hereof, the
               Trustee shall authenticate Series B Notes in exchange for Series
               A Notes accepted for exchange in the Exchange Offer, which Series
               B Notes shall not bear the legend set forth in clause (a) above,
               and the Registrar shall rescind any restriction on the transfer
               of such Notes, in each case unless the Holder of such Series A
               Notes is either (A) a broker-dealer, (B) a Person participating
               in the distribution (within the meaning of the Securities Act) of
               the Series A Notes or (C) a Person who is an affiliate (as
               defined in Rule 501 under the Securities Act) of the Company. The
               Company shall identify to the Trustee such Holders of the Notes
               in a written certification signed by an Officer of the Company
               and, absent certification from the Company to such effect, the
               Trustee shall assume that there are no such Holders.

                    (e) By its acceptance of any Note bearing the legend set
               forth in Section 2.06(7)(a) hereof, each Holder of such a Note
               acknowledges the restrictions on transfer of such Note set forth
               in this Indenture and in such legend and agrees that it will
               transfer such Note only as provided in this Indenture.

               (8) CANCELLATION AND/OR ADJUSTMENT OF GLOBAL NOTE. At such time
          as all beneficial interests in a Global Note have either been
          exchanged for Definitive Notes, redeemed, repurchased or canceled,
          such Global Note shall be returned to or retained and canceled by the
          Trustee. At any time prior to such cancellation, if any beneficial
          interest in a Global Note is exchanged for Definitive Notes, redeemed,
          repurchased or canceled, the principal amount of Notes represented by
          such Global Note shall be reduced and an endorsement shall be made on
          such Global Note, by the Trustee or the Note Custodian, at the
          direction of the Trustee to reflect such reduction.

               (9) General Provisions with Respect to Transfer and Exchange.

                    (a) To permit registration of transfers and exchanges, the
               Company shall execute and the Trustee shall authenticate,
               pursuant to the terms of this Indenture, Definitive Notes and
               Global Notes at the Registrar's request.

                    (b) 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 transfer tax or similar
               governmental charge payable in connection therewith (other than
               any such transfer taxes or similar governmental charges payable
               upon exchange or transfer pursuant to Section 2.09, 3.01, 4.11,
               4.12, and 9.05 hereof).

                    (c) Neither the Company nor the Registrar shall be required
               to register the transfer or exchange of any Note selected for
               redemption in whole or in part, except the unredeemed portion of
               any Note being redeemed in part.

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

                    (e) The Company shall not be required to issue or register
               the transfer or exchange of Notes during a period beginning at
               the opening of 15 days before the day of any selection of Notes
               for redemption under Section 3.02 and ending at the close of
               business on the day of selection.

                    (f) Prior to due presentment for registration of transfer of
               any Note, the Trustee, any Agent and the Company may deem and
               treat the Person in whose name any Note is registered as the
               absolute owner of such Note for the purpose of receiving payment
               of principal of, and premium, interest and Liquidated Damages, if
               any, on such Note, and neither the Trustee, any Agent nor the
               company shall be affected by notice to the contrary.

                    (g) The Trustee shall authenticate Definitive Notes and
               Global Notes in accordance with the provisions of Section 2.02
               hereof.

                    (h) Neither the Company nor the Trustee shall be liable for
               any delay by the Depository in identifying the beneficial owners
               of the Notes and each such Person may conclusively rely on, and
               shall be protected in relying on, instructions from the
               Depository for all purposes (including with respect to the
               registration and delivery, and the respective principal amounts,
               of any Notes to be issued).

<PAGE>   37


                    (i) Members of, or participants in, the Depository shall
               have no rights under this Indenture with respect to any Global
               Note held on their behalf by the Depository, or the Trustee as
               the Note Custodian, or under the Global Note, and the Depository
               may be treated by the Company, the Trustee and any agent of the
               Company or the Trustee as the absolute owner of the Global Note
               for all purposes whatsoever. Notwithstanding the foregoing,
               nothing herein shall (x) 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
               the Depository or (y) impair, as between the Depository and
               members of, or participants in, the Depository, the operation of
               customary practices governing the exercise of the rights of a
               Holder of any Note.

     SECTION 2.07 REPLACEMENT NOTES. If any mutilated Note is surrendered to the
Company or the Trustee, or the Company and the Trustee receive evidence to their
satisfaction of the destruction, loss or theft of any Note, and there is
delivered to the Company and the Trustee such security or indemnity as may be
required by them to save each of them harmless, then, in the absence of notice
to the Company or the Trustee that such Note has been acquired by a bona fide
purchaser, the Company shall execute, and upon its written request, the Trustee
shall authenticate and make available for delivery, in exchange for any such
mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note
of like tenor and principal amount, bearing a number not contemporaneously
outstanding.

     In case any such mutilated, destroyed, lost or stolen Note has become or is
about to become due and payable, or is about to be purchased by the Company
pursuant to Article 3 hereof, the Company in its discretion may, instead of
issuing a new Note, pay or purchase such Note, as the case may be.

     Upon the issuance of new Notes under this Section 2.07, 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) in connection therewith.

     Every new Note issued pursuant to this Section 2.07 in lieu of any
mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all benefit of this Indenture equally and proportionately
with any and all other Notes duly issued hereunder.

     The provisions of this Section 2.07 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 Notes.

     SECTION 2.08 OUTSTANDING NOTES; DETERMINATIONS OF HOLDERS' ACTION. Notes
outstanding at any time are all the Notes authenticated by the Trustee except
for those cancelled by it, those delivered to it for cancellation, those
referred to in Section 2.07 hereof, or purchased by the Company pursuant to
Article 3 hereof and those described in this Section 2.08 as not outstanding. A
Note does not cease to be outstanding because the Company or an Affiliate
thereof holds the Note; PROVIDED, HOWEVER, that in determining whether the
holders of the requisite principal amount of Notes have given or concurred in
any request, demand, authorization, direction, notice, consent or waiver
hereunder, Notes owned by the Company, any other obligor upon the Notes or any
Affiliate of the Company or such other obligor shall be disregarded and deemed
not to be outstanding, except that, in determining whether the Trustee shall be
protected in relying upon such request, demand, authorization, direction,
notice, consent or waiver, only Notes which a Trust Officer of the Trustee knows
based upon an examination of the Register to be so owned shall be so
disregarded. Subject to the foregoing, only Notes outstanding at the time of
such determination shall be considered in any such determination (including
determinations pursuant to Articles 6 and 9).

     If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Note is
held by a bona fide purchaser.

     If the Paying Agent (other than the Company) holds, in accordance with this
Indenture, at maturity or on a Redemption Date, money sufficient to pay the
Notes payable on that date, then immediately on the date of maturity or such
Redemption Date, as the case may be, such Notes shall cease to be outstanding
and interest, if any, on such Notes shall cease to accrue.

     SECTION 2.09 TEMPORARY NOTES. Pending the preparation of Definitive Notes,
the Company may execute, and upon receipt of an Officers' Certificate from the
Company, the Trustee shall authenticate and make available for delivery,
temporary Notes which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially of the tenor
of the Definitive Notes in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the
Officers of the Company executing such Notes may determine, as conclusively
evidenced by their execution of such Notes.

     If temporary Notes are issued, the Company will cause Definitive Notes to
be prepared without unreasonable delay. After the preparation of Definitive
Notes, the temporary Notes shall be exchangeable for Definitive Notes upon
surrender of the temporary Notes at the office or agency of the Company
designated for such purpose pursuant to Section 2.03 hereof, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary Notes,
the Company shall execute and the Trustee, upon receipt of an Officers'
Certificate from the Company, shall authenticate and make available for delivery
in exchange therefor a like principal amount of Definitive Notes of authorized
denominations. Until so exchanged, the temporary Notes shall in all respects be
entitled to the same benefits under this Indenture as Definitive Notes.

<PAGE>   39


     SECTION 2.10 CANCELLATION. All Notes surrendered for payment, purchase by
the Company, redemption by the Company pursuant to Article 3 hereof, 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 cancelled by
it. The Company may at any time deliver to the Trustee for cancellation any
Notes previously authenticated and made available for delivery hereunder which
the Company may have acquired in any manner whatsoever, and all Notes so
delivered shall be promptly cancelled by the Trustee. The Company may not
reissue, or issue new Notes to replace Notes it has paid or delivered to the
Trustee for cancellation. No Notes shall be authenticated in lieu of or in
exchange for any Notes cancelled as provided in this Section 2.10, except as
expressly permitted by this Indenture. All cancelled Notes held by the Trustee
shall be destroyed by the Trustee.

     SECTION 2.11 CUSIP NUMBER. The Company, in issuing the Notes may use
"CUSIP" numbers (if then generally in use), and the Trustee shall use CUSIP
numbers in notices of redemption or exchange as a convenience to Holders;
provided that any such notice shall state that no representation is made as to
the correctness of such numbers either as printed on the Notes or as contained
in any notice of redemption or exchange and that reliance may be placed only on
the other identification number printed on the Notes and any redemption shall
not be affected by any defect in or omission of such numbers.

     SECTION 2.12 DEFAULTED INTEREST. If the Company defaults on a payment of
interest on the Notes, it shall pay the defaulted interest, plus (to the extent
lawful) any interest payable on the defaulted interest (as provided in Section

                                   REDEMPTION
                                   ----------

     SECTION 3.01 RIGHT TO REDEEM; NOTICES TO TRUSTEE. At any time on and after
March 15, 2002, the Company, at its option, may redeem the Notes for cash in
accordance with this Article 3 and the provisions of paragraph 6 of the Notes.
If the Company elects to redeem Notes pursuant to paragraph 6 of the Notes, it
shall notify the Trustee in writing of the Redemption Date, the principal amount
of Notes to be redeemed and the Redemption Price.

     The Company shall give the notice to the Trustee provided for in this
Section 3.01 at least 45 days before the Redemption Date (unless a shorter
notice shall be satisfactory to the Trustee).

     SECTION 3.02 SELECTION OF NOTES TO BE REDEEMED. If less than all the
outstanding Notes are to be redeemed at any time, the Trustee shall select the
Notes to be redeemed by lot or, if such method is prohibited by the rules of any
stock exchange on which the Notes are then listed, any other method the Trustee
considers reasonable. The Trustee shall make the selection at least 30 but not
more than 60 days before the Redemption Date from outstanding Notes not
previously called for redemption. Notes and portions of them the Trustee selects
shall be in principal amount of $1,000 or an integral multiple of $1,000.
Provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption. The Trustee shall notify the
Company promptly of the Notes or portions of Notes to be redeemed.

     SECTION 3.03 NOTICE OF REDEMPTION. At least 30 days but not more than 60
day before a Redemption Date, the Company shall mail or cause to be mailed a
notice of redemption by first-class mail, postage prepaid, to each Holder of
Notes to be redeemed at the Holder's last address as it shall appear on the
registry book. A copy of such notice shall be mailed to the Trustee on the same
day the notice is mailed to Holders of Notes.

     The notice shall identify the Notes to be redeemed and shall state:

          (1) the Redemption Date;

          (2) the Redemption Price;

          (3) the CUSIP number (subject to the provisions of Section 2.11
     hereof);

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

          (5) that Notes called for redemption must be surrendered to the Paying
     Agent to collect the Redemption Price;

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

<PAGE>   41


          (7) that, unless the Company defaults in making such redemption
     payment together with accrued and unpaid interest and Liquidated Damages,
     if any, to the Redemption Date, interest will cease to accrue on Notes
     called for redemption on and after the Redemption Date.

     At the Company's written request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense; PROVIDED,
HOWEVER, that in all cases, the text of such notice of redemption shall be
prepared or approved by the Company and the Trustee shall have no responsibility
whatsoever with regard to such notice being accurate or correct.

     SECTION 3.04 EFFECT OF NOTICE OF REDEMPTION. Once notice of redemption is
given, Notes called for redemption become due and payable on the Redemption Date
and at the Redemption Price. Upon the later of the Redemption Date and the date
such Notes are surrendered to the Paying Agent, such Notes called for redemption
shall be paid at the Redemption Price if money sufficient for that purpose has
been deposited as provided in Section 3.05 hereof.

     Notice of redemption shall be deemed to be given when mailed in the manner
provided in Section 3.03, whether or not the Holder receives the notice. In any
event, failure to give such notice, or any defect therein, shall not affect the
validity of the proceedings for the redemption of the Notes.

     SECTION 3.05 DEPOSIT OF REDEMPTION PRICE. Prior to the Redemption Date, the
Company shall deposit with the Paying Agent (or if the Company or a Subsidiary
or an Affiliate of either of them is the Paying Agent, shall segregate and hold
in trust) money sufficient to pay the Redemption Price of all Notes to be
redeemed on that date other than Notes or portions of Notes called for
redemption which prior thereto have been delivered by the Company to the Trustee
for cancellation.

     SECTION 3.06 NOTES REDEEMED IN PART. Upon surrender of a Note that is
redeemed in part, the Company shall execute, and the Trustee shall authenticate
at the expense of the Company and make available for delivery to the Holder, a
new Note in an authorized denomination equal in principal amount to the
unredeemed portion of the Note surrendered.

                                    ---------

     SECTION 4.01 PAYMENT OF NOTES. The Company shall pay the principal of,
premium, if any, and interest (including interest accruing on or after the
filing of a petition in bankruptcy or reorganization relating to the Company,
whether or not a claim for post-filing interest is allowed in such proceeding)
on the Notes on (or prior to) the dates and in the manner provided


                                       36


<PAGE>   42


in the Notes or pursuant to this Indenture. An installment of principal,
premium, if any, or interest shall be considered paid on the applicable date due
if on such date the Trustee or the Paying Agent shall have received before 12:00
noon on such date and shall then hold, in accordance with this Indenture, money
sufficient to pay all of such installment then due. The Company shall pay all
Liquidated Damages, if any, in the same manner on the dates and in the amounts
set forth in the Registration Rights Agreement. If any Liquidated Damages become
payable, the Company shall not later than three Business Days prior to the date
that any payment of Liquidated Damages is due (i) deliver an Officers'
Certificate to the Trustee setting forth the amount of Liquidated Damages
payable to Holders and (ii) instruct the Paying Agent to pay such amount of
Liquidated Damages to Holders entitled to receive such Liquidated Damages. The
Company shall pay interest on overdue principal and premium, if any, and
interest on overdue installments of interest and Liquidated Damages, if any
(including interest accruing on or after the filing of a petition in bankruptcy
or reorganization relating to the Company whether or not a claim for post-filing
interest is allowed in such proceeding), to the extent lawful, at 2% above the
rate per annum borne by the Notes, which interest on overdue interest shall
accrue from the date such amounts became overdue.

     SECTION 4.02  Reports.
                   -------

     Holders of Notes (i) all quarterly and annual financial information that

     certified public accountants and (ii) all reports that would be required to
     be filed with the SEC on Form 8-K if the Company were required to file such
     reports. In addition, whether or not required by the rules and regulations
     of the SEC, the Company will file a copy of all such information with the
     SEC for public availability (unless the SEC will not accept such filing)
     and make such information available to investors or prospective investors
     who request it in writing.

              (2) If the Company is not subject to and in compliance with the
     informational requirements of Sections 13 or 15(d) of the Exchange Act at
     any time while the Notes constitute "restricted securities" within the
     meaning of the Securities Act, it will furnish to the Holders of the Notes
     and prospective purchasers of the Notes designated by Holders of the Notes,
     upon their request, the information required to be delivered pursuant to
     Rule 144A(d)(4) under the Securities Act until such time as the Company
     either exchanges all of the Notes for the Exchange Notes or has registered
     under the Securities Act and continues to maintain a registration statement
     with respect to the resale of all of the Notes pursuant to the Registration
     Rights Agreement.

     expense provide the Trustee with a sufficient number of copies thereof for
     delivery at the Company's expense by the Trustee, all reports and other
     documents and information that the Company may be required to deliver to
     the Holders under this Section 4.02.

     SECTION 4.03 Compliance Certificates.
                  -----------------------

              (1) The Company shall deliver to the Trustee within 90 days after
     the end of each of the Company's fiscal years an Officers' Certificate
     executed by Officers of the Company, stating whether or not the signers
     know of any Default or Event of Default. Such certificate shall contain a
     certification from the principal executive officer, principal financial
     officer or principal accounting officer of the Company as to his or her
     knowledge of the Company's compliance with all conditions and covenants
     under this Indenture. For purposes of this Section 4.03(1), such compliance

     notice provided under this Indenture. If they do know of such a Default or
     Event of Default, the certificate shall describe any such Default or Event
     of Default, and its status.

              (2) So long as not contrary to the then current recommendation of
     the American Institute of Certified Public Accountants, the Company shall

     written statement by the Company's independent certified public accountants
     stating (a) that their audit examination has included a review of the terms
     of this Indenture and the Notes as they relate to accounting matters, and
     (b) whether, in connection with their audit examination, any Default has
     come to their attention and, if such a Default has come to their attention,
     specifying the nature and period of the existence thereof; PROVIDED,
     HOWEVER, that the independent certified public accountants delivering such
     statement shall not be liable in respect of such statement 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 GAAP.

              (3) The Company shall deliver to the Trustee as soon as possible

Indenture may be served. The corporate trust office of the Trustee at the
address specified in Section 10.02 hereof shall initially be such office or
agency for all of the aforesaid purposes. The Company shall give prompt written
notice to the Trustee of any change of location of such office or agency. If at
any time the Company shall fail to maintain or cause to be maintained 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 10.02 hereof.

     The Company may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations. The Company will
give prompt written notice to the Trustee of any such designation or rescission

     the amount of such cumulative Consolidated Net Income divided by the number
     of full fiscal quarters of the Company in the applicable period exceeds
     $5,250,000, then such amount shall equal (i) 50% of the product of
     $5,250,000 multiplied by the number of full fiscal quarters in such period
     plus (ii) 75% of the amount in excess of the product of $5,250,000

     convertible into any security other than such Capital Stock), to the extent
     such Indebtedness is actually converted into such Capital Stock; (C) an
     amount equal to any cash and the Fair Market Value (at the time of receipt)
     of other assets received by the Company or any of its Restricted
     Subsidiaries after the date of the issuance of the Notes as a dividend or
     other distribution from any Unrestricted Subsidiary; (D) the Fair Market

     accordance with the provisions of this Indenture; and (E) $35,000,000; or

          (3) the Company could not incur at least $1.00 of additional
     Indebtedness pursuant to the first paragraph of Section 4.07 hereof.

     The foregoing provisions shall not prohibit, so long as no Default or Event
of Default shall have occurred and be continuing or shall occur as a consequence
thereof, (i) the payment of any dividend within 60 days after the date of
declaration thereof, if at such date of declaration such payment would have
complied with the provisions of this Indenture; (ii) the declaration and payment

Subsidiary shall not exceed 25% of the Consolidated Net Income of such Reporting
Subsidiary for


                                       40


<PAGE>   46


the immediately preceding fiscal year; (iii) the purchase, redemption,
acquisition, cancellation or other retirement for value of shares of Capital
Stock of the Company, options to purchase such shares or related stock
appreciation rights or similar securities held by current or former officers,
employees or directors (or their estates or beneficiaries under their estates)
of the Company or any Restricted Subsidiary; provided that the aggregate
consideration paid for such purchase, redemption, cancellation or other
retirement after the date hereof does not exceed $2,500,000 in the aggregate in

proceeds of a substantially concurrent offering of, shares of Capital Stock of
the Company.

     SECTION 4.07 LIMITATION ON ADDITIONAL INDEBTEDNESS. The Company shall not,
and shall not permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, issue, assume, guarantee or otherwise become directly
or indirectly liable with respect to (each, an "incurrence") any Indebtedness,

                    Owned Subsidiary of the Company that is a Restricted
                    Subsidiary which, at any time after such incurrence, ceases
                    to be a Wholly-Owned Subsidiary, then all such Indebtedness
                    in excess of the amount of Allowable Subsidiary Loans shall
                    be deemed to have been incurred at the time such former
                    Wholly-Owned Subsidiary ceases to be a Wholly-Owned
                    Subsidiary of the Company;

                         (vii) Indebtedness of a Restricted Subsidiary under a
                    guaranty of Indebtedness of the Company (other than the
                    Notes) which causes such Restricted Subsidiary to become a
                    Subsidiary Guarantor pursuant to the provisions of Section
                    4.14 hereof;

                    the obligations of the Company and its Restricted
                    Subsidiaries under such Interest Rate Agreements does not
                    exceed the principal amount of such Indebtedness, and (b) in
                    the case of Currency Agreements that relate to other
                    Indebtedness, such Currency Agreements do not increase the

                    outstanding at any time other than as a result of

                    this Indenture if immediately prior to such designation such
                    Subsidiary was an Unrestricted Subsidiary, provided that,
                    after giving pro forma effect to such designation, such

                    the limitations set forth in the preceding paragraph of this
                    Section 4.07 (assuming for purposes of this clause (xii)

                    could become so liable in accordance with the provisions of

                    together with the principal amount of any remaining

                    Refinancing Indebtedness is substantially simultaneous with
                    the refinancing of the Indebtedness to be refinanced.

     For purposes of this Section 4.07, the accretion of original issue discount

     SECTION 4.08 LIMITATION ON SALE OR ISSUANCE OF PREFERRED STOCK OF
RESTRICTED SUBSIDIARIES. The Company shall not (i) permit any of its Restricted
Subsidiaries to issue or sell to any Person except the Company or a Wholly-Owned

                    and provided, further, that the extension, renewal or
                    refinancing of Indebtedness of the Company may not be
                    secured by Liens on assets of any Restricted Subsidiary
                    other than to the extent the Indebtedness being extended,
                    renewed or refinanced was at any time previously secured by

agreement effecting a refinancing of Indebtedness issued pursuant to any
agreement or instrument referred to in clause (d), (e), (f), (g) or (h) above,
provided that the terms and conditions of any such encumbrances and restrictions
are not materially less favorable to the Holders than those under the agreement
or instrument evidencing the Indebtedness being refinanced.

     The foregoing shall not restrict the ability of any Restricted Subsidiary
of the Company to grant any Lien to the extent otherwise permitted in this
Indenture.

     SECTION 4.11 REPURCHASE UPON CHANGE OF CONTROL. Upon the occurrence of a
Change of Control, each Holder will have the right to require the repurchase of

aggregate principal amount thereof plus accrued and unpaid interest and
Liquidated Damages, if any, to the date of purchase (the "Change of Control
Payment").

     Immediately following any Change of Control, the Company is required to
mail a notice to the Trustee and to each Holder stating: (i) that the Change of
Control Offer is being made pursuant to this Section 4.11 of this Indenture and
that all Notes tendered will be accepted for payment; (ii) the amount of the
Change of Control Payment and the purchase date (the "Change of Control Payment
Date"), which may not be earlier than 30 days nor later than 60 days from the
date such notice is mailed; (iii) that any Note not tendered will continue to
accrue interest; (iv) that, unless the Company defaults in the payment thereof,
all Notes accepted for payment pursuant to the Change of Control Offer will
cease to accrue interest on and after the Change of Control Payment Date; (v)
that Holders electing to have any Notes purchased pursuant to a Change of
Control Offer will be required to surrender the Notes to be purchased to the
Paying Agent at the address specified in the notice prior to the close of
business on the third Business Day preceding the Change of Control Payment Date;
(vi) that Holders will be entitled to withdraw Notes they have tendered on the
terms and conditions set forth in such notice; and (vii) that Holders whose
Notes are being purchased only in part will be issued new Notes (or book-entry
notation made with respect thereto) equal in principal amount to the unpurchased
portion of the Notes tendered; provided that the portion of each Note purchased
and each such new Note issued (or book-entry notation, if applicable) shall be
in a principal amount of $1,000 or an integral multiple thereof.

     On the Change of Control Payment Date, the Company will, to the extent
lawful: (i) accept for payment all Notes or portions thereof tendered pursuant
to the Change of Control Offer and not withdrawn; (ii) deposit with the Paying
Agent an amount sufficient to pay the Change of Control Payment in respect of
all Notes or portions thereof so tendered and not withdrawn; and (iii) deliver
or cause to be delivered to the Trustee all Notes so tendered and not withdrawn
together with an Officers' Certificate specifying the Notes or portions thereof
tendered to the Company. The Paying Agent will promptly mail to each Holder of
Notes so tendered and not withdrawn the Change of Control Payment in respect of
such Notes, and the Trustee will promptly authenticate and mail to such Holder a
new Note (or cause to be transferred by book entry) equal in principal amount to
any unpurchased portion of the Notes surrendered; provided that each such


                                       47

new Note shall be in a principal amount of $1,000 or an integral multiple
thereof. The Company will publicly announce the results of the Change of Control
Offer on or as soon as practicable after the Change of Control Payment Date.

                    leased or otherwise transferred or conveyed to another
                    Person (other than pursuant to a bona fide pledge of assets
                    to secure Indebtedness made in accordance with this
                    Indenture), and the holders of the Company's common stock
                    outstanding immediately prior to such consolidation, merger,

                         (ii) there is filed a report on Schedule 13D or 14D-1
                    (or any successor schedule, form or report) pursuant to the
                    Exchange Act disclosing that any person (defined, solely for
                    the purposes of the Change of Control provision, as the term
                    "person" is used in Section 13(d)(3) or Section 14(d)(2) of
                    the Exchange Act or any successor provision to either of the
                    foregoing) has become the beneficial owner (as the term
                    "beneficial owner" is defined under Rule 13d-3 or any
                    successor rule or regulation promulgated under the Exchange

                    Company's then outstanding securities entitled to vote
                    generally for the election of directors; provided, however,

                    of, or to own beneficially, (A) any securities tendered
                    pursuant to a tender or exchange offer made by or on behalf
                    of such person or any of such person's Affiliates or
                    associates until such tendered securities are accepted for
                    purchase or exchange thereunder, or (B) any securities if
                    such beneficial ownership (1) arises solely as a result of a
                    revocable proxy delivered in response to a proxy or consent
                    solicitation made pursuant to the applicable rules and
                    regulations under the Exchange Act, and (2) is not also then

                    of Directors or whose nomination for election by the
                    stockholders of the Company was approved by a vote of
                    66 2/3% of the directors then still in office who were
                    either directors at the beginning of such period or whose
                    election or nomination for election was previously so
                    approved) cease for any reason to constitute a majority
                    of the Board of Directors of the Company then in office.

     Notwithstanding the foregoing, a Change of Control shall not be deemed to
have occurred under clause (ii) of the immediately preceding paragraph solely by
virtue of the Company, any Subsidiary of the Company, any employee stock
ownership plan or any other employee benefit plan of the Company or any such
Subsidiary, any other Person holding securities of the Company for or pursuant
to the terms of any such employee benefit plan, or any Exempt Person, filing or
becoming obligated to file a report on Schedule 13D or Schedule 14D-1 (or any
successor schedule, form or report) under the Exchange Act disclosing beneficial
ownership by it of securities of the Company, whether in excess of 50% of the
combined voting power of the Company's then outstanding securities entitled to
vote generally for the election of directors or otherwise.

     SECTION 4.12 LIMITATION ON USE OF PROCEEDS FROM ASSET SALES. The Company
shall not, and shall not permit any of its Restricted Subsidiaries to, directly
or indirectly, consummate any Asset Sale unless (i) the Company or such
Restricted Subsidiary, as the case may be, receives consideration at the time of
any such Asset Sale having a value (including the Fair Market Value of any
non-cash consideration) at least equal to the Fair Market Value of the
securities or assets being sold or otherwise disposed of, and (ii) at least 75%
of the consideration from such Asset Sale is received in the form of cash, Cash
Equivalents (together with cash, "Cash Proceeds") or indebtedness for borrowed
money of the Company or such Restricted Subsidiary that is assumed by the
transferee of any such assets or any such indebtedness of any Restricted
Subsidiary of the Company whose stock is purchased by the transferee. Any Net
Cash Proceeds (a) in excess of the amount of cash applied by the Company or any
Restricted Subsidiary of the Company during the period beginning 12 months prior
to the date of the Asset Sale (but not prior to the issue date of the Notes) and
ending 12 months after the date of such Asset Sale to purchase any business that
is, or any properties and assets used primarily in, the same or a related
business as those owned and operated by the Company and its Subsidiaries as of
the issue date of the Notes or at the date of such Asset Sale and (b) not
applied within 12 months after the date of the Asset Sale to reduce Indebtedness
of the Company (other than Indebtedness which is subordinated by its terms to
the Notes) or any Restricted Subsidiary shall be deemed to be "Excess Proceeds."
When the aggregate amount of Excess Proceeds exceeds $15,000,000, the Company
shall make an offer (the "Excess Proceeds Offer") to apply the Excess Proceeds
to purchase the Notes. The Excess Proceeds Offer must be in cash in an amount
equal to 100% of the principal amount plus accrued and unpaid interest, if any,
thereon and Liquidated Damages, if any, to the date fixed for the closing of
such offer, substantially in accordance with the procedures for a Change of
Control Offer described in Section 4.11. To the extent that the aggregate amount
of Notes tendered pursuant to the Excess Proceeds Offer is less than the Excess
Proceeds, the Company may use the remaining Excess


                                       49


<PAGE>   55


Proceeds for general corporate purposes and such amounts shall no longer be
deemed Excess Proceeds. If the aggregate principal amount of Notes surrendered
by Holders exceeds the amount of Excess Proceeds, the Trustee shall select the
Notes to be purchased on a pro rata basis, subject to the limitation on the
authorized denominations of the Notes.

     SECTION 4.13 LIMITATION ON TRANSACTIONS WITH AFFILIATES. Except as
otherwise permitted by this Indenture, neither the Company nor any of its
Restricted Subsidiaries shall make any Investment, loan, advance, guaranty or
capital contribution to, or for the benefit of, or sell, lease or otherwise
transfer or dispose of any of its properties or assets to, or for the benefit
of, or purchase or lease any property or assets from, or enter into or amend any
contract, agreement or understanding with, or for the benefit of, any Affiliate
of the Company or any of its Restricted Subsidiaries, unless (i) such
transaction or series of transactions is in the best interests of the Company or
such Restricted Subsidiary based on all relevant facts and circumstances; (ii)
such transaction or series of transactions is fair to the Company or such
Restricted Subsidiary and on terms that are no less favorable to the Company or
such Restricted Subsidiary, as the case may be, than those that could have been
obtained in a comparable transaction on an arms' length basis from a Person that
is not an Affiliate of the Company or any of its Restricted Subsidiaries; and
(iii) (a) with respect to a transaction or series of related transactions
involving aggregate payments in excess of $2,500,000, the Board of Directors and
a majority of the Disinterested Directors shall approve such transaction or
series of transactions by a Board Resolution evidencing their determination that
such transaction or series of transactions complies with clauses (i) and (ii)
above, and (b) with respect to a transaction or series of transactions involving
aggregate payments equal to or greater than $10,000,000, the Company receives a
written opinion from a nationally recognized investment bank or valuation firm
or, with respect to a transaction requiring the valuation of real property, a
nationally recognized real estate appraisal firm, that such transaction or
series of transactions is fair to the Company from a financial point of view.

     The foregoing limitation shall not apply to: (i) any payment of money or
issuance of securities by the Company or any Restricted Subsidiary of the
Company pursuant to employment agreements or arrangements and employee benefit
plans, including reimbursement or advancement of out-of-pocket expenses and
directors' and officers' liability insurance; (ii) reasonable and customary
payments and other benefits (including indemnification) provided to directors
for service on the Board of Directors of the Company or any of its Restricted
Subsidiaries and reimbursement of expenses related thereto; or (iii)
transactions between the Company and any Restricted Subsidiary of the Company,
or between one Restricted Subsidiary of the Company and another Restricted
Subsidiary of the Company, provided that not more than 20% of such Restricted
Subsidiary is owned by any Affiliate of the Company or any of its Restricted
Subsidiaries (other than the Company or a Wholly-Owned Subsidiary of the
Company).

     SECTION 4.14 LIMITATION ON GUARANTIES BY SUBSIDIARIES. The Company shall
not permit any Restricted Subsidiary of the Company, directly or indirectly, to
assume, guarantee or in any other manner become liable with respect to any
Indebtedness of the Company or any Subsidiary Guarantor (other than the Notes),
unless (a) such liability is in respect of the Company Credit


                                       50

<PAGE>   56


Facility or (b) such Restricted Subsidiary is a Subsidiary Guarantor or
simultaneously executes and delivers (i) to the Company and the Trustee a
supplemental indenture to this Indenture providing for a Subsidiary Guaranty of
the Notes by such Restricted Subsidiary and any other Subsidiary Guarantors by
adding an Article 11 to this Indenture, in the form of Exhibit E hereto and (ii)
to the Trustee a Subsidiary Guaranty substantially in the form of Exhibit F
hereto.

     No Lien on the properties or assets of any Restricted Subsidiary of the
Company permitted by Section 4.09 shall constitute a guaranty of the payment of
any Indebtedness of the Company for purposes of this Section 4.14.

     The provisions of this Section 4.14 and any supplemental indenture referred
to in this Section 4.14 shall cease to have further force and effect (and if
there then exists any Subsidiary Guarantor, such Subsidiary Guarantor will be
deemed to be released from all obligations under its Subsidiary Guaranty) at
such time as Section 4.15 in the indenture governing the Company's 9 7/8% Notes
shall cease to have further force and effect (whether by reason of amendment,
redemption or repayment of such Indebtedness or otherwise), provided, however,
that if the instrument or other agreement governing any Indebtedness incurred to
refinance the 9 7/8% Notes includes such a covenant similar to Section 4.15 of
the indenture governing the 9 7/8% Notes, the provisions of this Section 4.14
and any supplemental indenture referred to in this Section 4.14 shall continue
in full force and effect for so long as such similar covenant remains in force
and effect.

     SECTION 4.15 PAYMENT OF TAXES AND OTHER CLAIMS. The Company shall pay or
discharge or cause to be paid or discharged, before any penalty accrues thereon,
(i) all material taxes, assessments and governmental charges levied or imposed
upon the Company or any of its Subsidiaries upon the income, profits or property
of the Company or any of its Subsidiaries and (ii) all material lawful claims
for labor, materials and supplies which, if unpaid, would by law become a Lien
upon the property of the Company or any of its Subsidiaries; provided that none
of the Company or any of its Subsidiaries shall be required to pay or discharge
or cause to be paid or discharged any such tax, assessment, charge or claims the
amount, applicability or validity of which is being contested in good faith by
appropriate proceedings and for which adequate provision has been made or where
the failure to effect such payment or discharge is not adverse in any material
respect to the Holders.

     SECTION 4.16 CORPORATE EXISTENCE. Subject to Article 5 hereof, the Company
will do or cause to be done all things necessary to preserve and keep in full
force and effect its corporate existence and the corporate, partnership or other
existence of any of its Subsidiaries in accordance with the respective
organizational documents of such Subsidiary and the rights (charter and
statutory), licenses and franchises of the Company and its Subsidiaries;
PROVIDED, HOWEVER, that the Company shall not be required to preserve any such
right, license or franchise, or the corporate, partnership or other existence of
any such Subsidiary, if the Board of Directors of the Company shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company and its Subsidiaries taken as a whole and that the loss
thereof is not


                                       51


<PAGE>   57


adverse in any material respect to the Holders.

     SECTION 4.17 MAINTENANCE OF PROPERTIES AND INSURANCE. The Company shall
cause all material properties owned by or leased to it or any of its
Subsidiaries and used or useful in the conduct of its business or the business
of such Subsidiary to be maintained and kept in normal condition, repair and
working order and supplied with all necessary equipment and shall cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section 4.17
shall prevent the Company or any of its Subsidiaries from discontinuing the
maintenance of any such properties, if such discontinuance is desirable in the
conduct of its business or the business of such Subsidiary

     The Company shall provide or cause to be provided, for itself and any of
its Subsidiaries, insurance (including appropriate self-insurance) against loss
or damage of the kinds customarily insured against by corporations similarly
situated and owning like properties, including, but not limited to, public
liability insurance, with reputable insurers in such amounts with such
deductibles and by such methods as shall be customary for corporations similarly
situated in the industry.

     SECTION 4.18 STAY, EXTENSION AND USURY LAWS. The Company covenants (to the
extent 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,
extension or usury law wherever enacted, now or at any time hereafter in force,
which may affect the covenants or the performance of this Indenture; and the
Company (to the extent it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law, and covenants that it will not resort to
any such law that would 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 has been enacted.

     SECTION 4.19 INVESTMENT COMPANY ACT. The Company shall not become an
investment company subject to registration under the Investment Company Act of
1940, as amended.

     SECTION 4.20 PAYMENTS FOR CONSENTS. The Company shall not, and shall not
permit any of its Subsidiaries to, directly or indirectly, pay or cause to be
paid any consideration whether by way of interest, fee or otherwise, to any
Holder of any Notes for or as an inducement to any consent, waiver or amendment
of any of the terms or provisions of this Indenture or the Notes unless such
consideration is offered to be paid or agreed to be paid to all Holders of the
Notes which so consent, waive or agree to amend in the time frame set forth in
solicitation documents relating to such consent, waiver or agreement.

     SECTION 4.21 COVENANT TO COMPLY WITH SECURITIES LAWS UPON PURCHASE OF
NOTES. In connection with any offer to purchase or purchase of Notes under
Section 4.11 or 4.12 hereof, the Company shall (i) comply with Rule 14e-1 under
the Exchange Act, and (ii) otherwise comply


                                       52

with all Federal and state securities laws so as to permit the rights and
obligations under Sections 4.11 and 4.12 hereof to be exercised in the time and

     have continued for the period and after receipt by the Company of the
     notice specified below.

     "Bankruptcy Law" means Title 11, United States Code, or any similar Federal
or state law for the relief of debtors. "Custodian" means any receiver, trustee,
assignee, liquidator, sequestrator, custodian or similar official under any
Bankruptcy Law.

the Trustee notifies the Company, or the Holders of at least 25% in aggregate
principal amount of the Notes at the time outstanding notify the Company and the
Trustee, of the Default and the Company does not cure such Default within 30
days after receipt of such notice. Any such notice must specify the Default,
demand that it be remedied and state that such notice is a "Notice of Default."

     In the case of any Event of Default (other than as a result of the failure
to comply with Section 4.11) occurring by reason of any willful action (or
inaction) taken (or not taken) by or on behalf of the Company with the intention
of avoiding payment of the premium which the Company would have to pay if the
Company then had elected to redeem the Notes, an equivalent premium shall also
become and be immediately due and payable to the extent permitted by law,
anything in this Indenture or in the Notes contained to the contrary
notwithstanding.

     In the case of an Event of Default as a result of a failure to comply with
Section 4.11 hereof occurring by reason of any willful action (or inaction)
taken (or not taken) by or on behalf of the Company with the intention of
avoiding payment of the premium which the Company would have to pay pursuant to
Section 4.11, such premium shall also become and be immediately due and payable
at such time as the principal and interest on the Notes become due and payable
pursuant to Section 6.02 hereof to the extent permitted by law, anything in this
Indenture or in the Notes contained to the contrary notwithstanding.

     SECTION 6.02 ACCELERATION. If any Event of Default (other than an Event of
Default specified in clause (5) or (6) of Section 6.01 hereof) occurs and is
continuing, the Trustee may, by Notice to the Company, or the Holders of at
least 25% in aggregate principal amount of the Notes then outstanding, by notice
to the Company and the Trustee, and the Trustee shall, upon the request of such
Holders, declare the unpaid principal, premium, if any, and accrued interest on
and Liquidated Damages, if any, with respect to, the Notes to be due and payable
immediately. If any Event or Default under clause (5) or (6) of Section 6.01
hereof occurs, all unpaid principal, premium, if any, interest on and Liquidated
Damages, if any, with respect to the Notes then outstanding shall IPSO FACTO
become and be immediately due and payable without declaration or other act on
the part of the Trustee or any Holder. The Holders of at least a majority in
aggregate principal amount of the Notes then outstanding by written notice to
the Trustee and to the Company may rescind an acceleration and its consequences
(except an acceleration due to a default in payment of principal of, premium, if
any, and accrued interest on and Liquidated Damages, if any, with respect to,
the Notes) if all existing Events of Default have been cured or waived except
non-payment of principal of, premium, if any, and accrued interest on and


                                       57


<PAGE>   63


Liquidated Damages, if any, that has become due solely because of the
acceleration.

     SECTION 6.03 OTHER REMEDIES. If any 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, premium, if any, or interest
on the Notes or to enforce the performance of any provision of the Notes or this
Indenture.

     The Trustee may maintain a proceeding even if the Trustee does not possess
any of the Notes or does not produce any of the Notes in the proceeding. A delay
or omission by the Trustee or any Holder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of, or acquiescence in, the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

     SECTION 6.04 WAIVER OF PAST DEFAULTS. The Holders of not less than a
majority in aggregate principal amount of the Notes at the time outstanding, by
notice to the Trustee (and without notice to any other Holder), may waive an
existing Default or Event of Default and its consequences except (i) an Event of
Default described in Section 6.01(1) hereof, or (ii) a Default in respect of a
provision that under Section 9.02 hereof cannot be amended without the consent
of each Holder affected. When a Default or Event of Default is waived, it is
deemed cured and shall cease to exist, but no such wavier shall extend to any
subsequent or other Default or Event of Default or impair any consequent right.

     SECTION 6.05 CONTROL BY MAJORITY. The Holders of not less than a majority
in aggregate principal amount of the Notes at the time outstanding may direct,
by an instrument or concurrent instruments in writing delivered to the Trustee,
the time, method and place of conducting any proceeding for any remedy available
to the Trustee or of exercising any trust or power conferred on the Trustee.
However, the Trustee may refuse to follow any direction that conflicts with law
or this Indenture or that the Trustee determines in good faith is unduly
prejudicial to the rights of other Holders or would involve the Trustee in
personal liability. Subject to the provisions of Section 315 of the TIA, the
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

     SECTION 6.06 LIMITATION ON SUITS. Except as provided in Section 6.07
hereof, a Holder may not pursue any remedy with respect to this Indenture or the
Notes unless:

          (1) the Holder gives to the Trustee written notice stating that an
     Event of Default is continuing;

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

          (3) such Holder or Holders offer to the Trustee reasonable security or
     indemnity against any loss, liability or expense satisfactory to the
     Trustee;


                                       58


<PAGE>   64


          (4) the Trustee does not comply with the request within 30 days after
     receipt of the notice, the request and the offer of security or indemnity;
     and

          (5) the Holders of a majority in aggregate principal amount of the
     Notes at the time outstanding do not give the Trustee a direction
     inconsistent with the request during such 30-day period.

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

     SECTION 6.07 RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
the principal amount, premium, if any, or interest, or Liquidated Damages, if
any, in respect of the Notes held by such Holder, on or after the respective due
dates expressed in the Notes, any Redemption Date, any Change in Control Payment
Date or any payment date respecting an Excess Proceeds Offer, or to bring suit
for the enforcement of any such payment on or after such respective dates shall
not be impaired or affected adversely without the consent of each such Holder.

     SECTION 6.08 COLLECTION SUIT BY TRUSTEE. If an Event of Default described
in Section 6.01(1) hereof 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 Notes for the whole amount owing with respect to the
Notes and the amounts provided for in Section 7.07 hereof.

     SECTION 6.09 TRUSTEE MAY FILE PROOFS OF CLAIM. In case of the pendency of
any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Company or the property of the Company or to any other obligor on the Notes
or the property of such obligor, the Trustee shall be entitled and empowered, by
intervention in such proceeding or otherwise:

          (1) to file and prove a claim for the whole amount of the principal
     amount, premium, if any, and interest on the Notes and to file such 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 of the Holders allowed in such judicial proceeding; and

          (2) to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;

and any Custodian in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable


                                       59


<PAGE>   65


compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

     SECTION 6.10 PRIORITIES. If the Trustee collects any money pursuant to this
Article 6, it shall pay out the money in the following order:

     FIRST:           to the Trustee for amounts due under Section 7.07 hereof;

     SECOND:          to Holders for amounts due and unpaid on the Notes for 
the principal amount, premium, if any, interest, if any, and Liquidated Damages,
if any, as the case may be, ratably, without preference or priority of any kind,
according to such amounts due and payable on the Notes; and

     THIRD:           the balance, if any, to the Company or to the Person or
Persons otherwise entitled thereto.

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 6.10.

     SECTION 6.11 UNDERTAKING FOR COSTS. In any suit for the enforcement of any
right or remedy under this Indenture or in any suit against the Trustee for any
action taken or omitted by it as Trustee, a court in its discretion may require
the filing by any party litigant (other than the Trustee) 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 and expenses,
against any party litigant in the suit, having due regard to the merit and good
faith of the claims or defense made by the party litigant. This Section 6.11
does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section
6.07 hereof or a suit by Holder of more than 10% in aggregate principal amount
of the Notes at the time outstanding.

     SECTION 6.12 RESTORATION OF RIGHTS AND REMEDIES. If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this
Indenture, any Note or any Subsidiary Guaranty and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case the Company, each
Subsidiary Guarantor, if any, the Trustee and the Holders shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been
instituted.

                                     -------

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

          (1) If an Event of Default has occurred and is continuing (and is not
     cured), the Trustee shall exercise the rights and powers vested in it by
     this 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 his own affairs.

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

          (a) the Trustee need perform only those duties that are specifically
     set forth in this Indenture and not others and no implied covenants or
     obligations shall be read into this Indenture against the Trustee and the
     duties of the Trustee shall be determined solely by the express provisions
     of this Indenture; and

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

     The Trustee shall not be liable for any interest on any money received by
     it.

          (3) The Trustee may not be relieved from liability for its own
     negligent action, its own negligent failure to act or its willful
     misconduct, except that:

          (a) this paragraph (3) does not limit the effect of paragraph (2) of
     this Section 7.01;

          (b) the Trustee shall not be liable for any error of judgment made in
     good faith by any Trust Officer unless it is proved that the Trustee was
     negligent in ascertaining the pertinent facts; and

          (c) 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 Section 6.04 or 6.05 hereof.

          (4) Whether or not expressly so provided, every provision of this
     Indenture that


                                       61


<PAGE>   67


     in any way relates to the Trustee is subject to paragraphs (1), (2), (3),
     (5) and (7) of this Section 7.01 and Section 7.02.

          (5) The Trustee may refuse to perform any duty or exercise any right
     or power or extend or risk its own funds or otherwise incur any financial
     liability unless it receives reasonable security or indemnity satisfactory
     to it against any loss, liability or expense.

          (6) Money held by the Trustee in trust hereunder need not be
     segregated from other funds except to the extent required by law. The
     Trustee shall be under no liability for interest on any money held by it
     hereunder.

          (7) The Trustee shall not be deemed to have knowledge of the existence
     of any fact or matter unless such fact or matter is known to one of its
     Trust Officers.

     SECTION 7.02 Rights of Trustee.
                  ------------------
          (1) The Trustee may rely on any document believed by it to be genuine
     and to have been signed or presented by the proper Person. The Trustee need
     not investigate any fact or matter stated in any such document but the
     Trustee may, in its discretion, make such further inquiry or investigation
     into such facts or matters stated in any such document as it sees fit.

          (2) Before the Trustee acts or refrains from acting, it may require an
     Officers' Certificate and an Opinion of Counsel. The Trustee shall not be
     liable for any action it takes or omits to take in good faith in reliance
     on such Officers' Certificate and Opinion of Counsel.

          (3) The Trustee may act through agents and shall not be responsible
     for the misconduct or negligence of any agent appointed with due care.

          (4) The Trustee shall not be liable for any action it takes or omits
     to take in good faith which it believes to be authorized or within its
     rights or powers.

          (5) The Trustee may consult with counsel of its selection and the
     advice of such counsel or any Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action taken, suffered or
     omitted by it hereunder in good faith and in reliance thereon.

          (6) 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 Holders pursuant to this Indenture, unless such Holders shall
     have offered to the Trustee reasonable security and indemnity satisfactory
     to it against the costs, expenses and liabilities which might be incurred
     by it in compliance with such request or direction.

     SECTION 7.03 INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its individual or
any other capacity may become the owner or pledgee of Notes and may otherwise
deal with the Company or its Affiliates with the same rights it would have if it
were not Trustee. Any Paying Agent, Registrar or co-registrar may do the same
with like rights. However, the Trustee must comply with Section 7.10 and 7.11
hereof.

     SECTION 7.04 TRUSTEE'S DISCLAIMER. The Trustee makes no representation as
to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company's use of the proceeds from the Notes, and it shall
not be responsible for any statement in the registration statement for the Notes
under the Securities Act of 1933, as amended (the "Securities Act") (other than
statements contained in the Form T-1 filed with the SEC under the TIA) or in
this Indenture or the Notes (other than its certificate of authentication), or
the determination as to which beneficial owners are entitled to receive any
notices hereunder.

     SECTION 7.05 NOTICE OF DEFAULTS. If a Default occurs and is continuing and
if it is known to the Trustee, the Trustee shall mail to each Holder as their
names and addresses appear on the Note Register, notice of the Default within 90
days after it becomes known to the Trustee unless such Default shall have been
cured or waived. Except in the case of a Default described in Section 6.01(1)
hereof, the Trustee may withhold such notice if and so long as a committee of
Trust Officers in good faith determines that the withholding of such notice is
in the interests of Holders.

     SECTION 7.06 REPORTS BY TRUSTEE TO HOLDERS. Within 60 days after each May
15th beginning with May 15, 1997, the Trustee shall mail to each Holder a brief
report dated as of such May 15th in accordance with and to the extent required
under Section 313 of the TIA.

     A copy of each report at the time of its mailing to Holders shall be filed
with the Company, the SEC and each stock exchange on which the Notes are listed.
The Company agrees to promptly notify the Trustee whenever the Notes become
listed on any stock exchange and of any delisting thereof.

     SECTION 7.07  Compensation and Indemnity.  The Company agrees:
                   --------------------------

          (1) To pay to the Trustee from time to time such compensation as shall
     be agreed in writing between the Company and the Trustee for all services
     rendered by it hereunder (which compensation shall not be limited by any
     provision of law in regard to the compensation of a trustee of an express
     trust);

          (2) To reimburse the Trustee upon its request for all reasonable
     expenses, disbursements and advances incurred or made by the Trustee in
     accordance with any provision of this Indenture (including the reasonable
     compensation and the expenses, disbursements and advances of its agents and
     counsel and other persons not regularly in


                                       63


<PAGE>   69


     its employ), including all reasonable expenses, disbursements and advances
     incurred or made by the Trustee in connection with any membership on any
     creditor's committee, except any such expense, disbursement or advance as
     may be attributable to its negligence or bad faith; and

          (3) To indemnify the Trustee, its officers, directors and
     shareholders, for, and to hold it harmless against, any and all loss,
     liability or expense, incurred without negligence or bad faith on its part,
     arising out of or in connection with the acceptance or administration of
     this trust, including the costs and expenses of defending itself against
     any claim or liability in connection with the exercise or performance of
     any of its powers or duties hereunder.

     The Trustee shall have a claim and lien prior to the Notes as to all
property and funds held by it hereunder for any amount owing it or any
predecessor Trustee pursuant to this Section 7.07, except with respect to funds
held in trust for the payment of principal of, premium, if any, or interest on
particular Notes.

     The Company's payment obligations pursuant to this Section 7.07 shall
survive the discharge of this Indenture. When the Trustee renders services or
incurs expenses after the occurrence of a Default specified in Section 6.01(5)
or (6) hereof, the compensation for services and expenses are intended to
constitute expenses of administration under any Bankruptcy Law.

     SECTION 7.08 REPLACEMENT OF TRUSTEE. The Trustee may resign by so notifying
the Company in writing at least 30 days prior to the date of the proposed
resignation; PROVIDED, HOWEVER, no such resignation shall be effective until a
successor Trustee has accepted its appointment pursuant to this Section 7.08.
The Holders of a majority in aggregate principal amount of the Notes at the time
outstanding may remove the Trustee by so notifying the Trustee in writing and
may appoint a successor Trustee subject to the consent of the Company. The
Trustee shall resign if:

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

               (2)  the Trustee is adjudged bankrupt or insolvent;

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

               (4)  the Trustee otherwise becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company shall promptly appoint, by a Board
Resolution, a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company. Thereupon the resignation or removal
of the retiring Trustee shall


                                       64


<PAGE>   70


become effective, and the successor Trustee shall have all the rights, powers
and duties of the Trustee under this Indenture. The successor Trustee shall mail
a notice of its succession to Holders. Subject to payment of all amounts owing
to the Trustee under Section 7.07 hereof and subject further to its lien under
Section 7.07, the retiring Trustee shall promptly transfer all property held by
it as Trustee to successor Trustee.

     If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of a majority in aggregate principal amount of the Notes at the time
outstanding may petition any court of competent jurisdiction for the appointment
of a successor Trustee.

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

     SECTION 7.09 SUCCESSOR TRUSTEE BY MERGER. If the Trustee consolidates with,
merges or converts into, or transfers all or substantially all its corporate
trust business or assets (including this Trusteeship) to, another corporation,
the resulting, surviving or transferee corporation without any further act shall
be the successor Trustee.

     SECTION 7.10 ELIGIBILITY; DISQUALIFICATION. The Trustee shall at all times
satisfy the requirements of TIA Section 310(a)(1) and (5). The Trustee shall
have a combined capital and surplus of at least $50,000,000 as set forth in its
most recently published annual report of condition. The Trustee shall comply
with TIA Section 310(b). In determining whether the Trustee has conflicting
interests as defined in TIA Section 310(b)(1), the provisions contained in the
proviso to TIA Section 310(b)(1) shall be deemed incorporated herein.

     SECTION 7.11 PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY. If and
when the Trustee shall be or become a creditor of the Company (or any other
obligor under the Notes), the Trustee shall be subject to the provisions of the
TIA regarding the collection of claims against the Company (or any such other
obligor).

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

     SECTION 8.01 DISCHARGE OF LIABILITY ON NOTES. When (i) the Company delivers
to the Trustee all outstanding Notes (other than Notes replaced pursuant to
Section 2.07 hereof or Notes which are purchased pursuant to Section 4.11 or
4.12 hereof or Notes for whose payment money has theretofore been held in trust
and thereafter repaid to the Company, as provided in Section 8.02 hereof) for
cancellation or (ii) the Company irrevocably deposits with the Trustee money
and/or 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 and interest in such amounts and at such times as are sufficient,
without consideration of any reinvestment of such interest, to pay principal of,
premium, if any, interest on, or Liquidated Damages with respect to the
outstanding Notes (other than Notes replaced pursuant to Section 2.07 hereof) to
maturity or redemption, as the case may be, in accordance with the terms of this
Indenture and the Notes issued hereunder, and if in either case the Company pays
all other sums payable here under by the Company, then this Indenture shall,
subject to Sections 2.06 and 7.07 hereof, and each Subsidiary Guaranty, if any,
shall except as to the obligations of the Subsidiary Guarantor thereunder in
respect of such Sections, cease to be of further effect. The Trustee shall join
in the execution of any documents prepared by the Company acknowledging
satisfaction and discharge of this Indenture and each such Subsidiary Guaranty
on written demand of the Company accompanied by an Officers' Certificate and
Opinion of Counsel and at the cost and expense of the Company. In the case of
any such deposit pursuant to clause (ii) above, the obligation to pay the
principal of and any interest on such Notes and the obligations under Section
7.07 hereof shall continue until the Notes are paid in full (provided that the
provisions of Section 7.07 hereof shall survive the payment of the Notes and
discharge of the Indenture). The Company will be entitled to make such a deposit
if the Company has delivered to the Trustee (i)(A) a ruling directed to the
Trustee from the Internal Revenue Service to the effect that the holders of the
Notes will not recognize income, gain or loss for federal income tax purposes as
a result of such deposit and defeasance of this Indenture and will be subject to
federal income tax on the same amount and in the same manner and at the same
times, as would have been the case if such deposit and defeasance had not
occurred, or (B) an opinion of counsel, reasonably satisfactory to the Trustee,
to the same effect as clause (i)(A) above, (ii) an Opinion of Counsel (who may
be an employee of or counsel for the Company), and an Officers' Certificate in
accordance with this Indenture and (iii) a report from a nationally recognized
firm of independent public accountants stating that the amount of such deposit
is sufficient to pay and discharge the amounts described in clause (ii) above
with respect to the Notes.

     If the Trustee or Paying Agent is unable to apply any money in accordance
with this Section 8.01 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the obligations of the Company and each Subsidiary Guarantor
under this Indenture and the Notes shall be revived and reinstated as though no
deposit had occurred pursuant to this Section 8.01 until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with
this Section 8.01; PROVIDED, HOWEVER, that if the Company or any Subsidiary
Guarantor, as the case may be, makes any payment of interest on or principal of
any Note following the reinstatement of its obligations, the Company or any
Subsidiary Guarantor, as the case may be, shall be subrogated to the right of
the Holders of such Notes to receive such payment from the money held by the
Trustee or Paying Agent.

     SECTION 8.02 REPAYMENT TO THE COMPANY OR SUBSIDIARY GUARANTORS. Subject to

any excess money or U.S. Government Obligations held by them at any time. The
Trustee and the Paying Agent shall adhere to applicable law and appropriate
regulations in the disposition of any unclaimed funds. After return to the
Company or any SUBSIDIARY Guarantor, Holders entitled to the money must look to
the Company for payment as general creditors unless an applicable abandoned
property law designates another Person, and all liability of the Trustee and
such Paying Agent with respect to such money shall cease.

                                   AMENDMENTS
                                   ----------

     SECTION 9.01 WITHOUT CONSENT OF HOLDERS. From time to time, when authorized
by Board Resolutions of each of them, the Company and the Trustee, without
notice to or the consent of the Holders of the Notes issued hereunder, may amend
or supplement this Indenture or the Notes as follows:

          (1) to cure any ambiguity, defect or inconsistency;

          (2) to comply with Article 5 hereof;

          (3) to provide for uncertificated Notes in addition to or in place of
     certificated Notes so long as such uncertificated Notes are in registered
     form for purposes of the Internal Revenue Code of 1986, as amended;

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

          (5) to comply with any requirement of the SEC in connection with the
     qualification of this Indenture under the TIA; or

          (6) to add any Subsidiary of the Company as a Subsidiary Guarantor.

     SECTION 9.02 WITH CONSENT OF HOLDERS. With the consent of the Holders of at
least a majority in aggregate principal amount of the Notes at the time
outstanding, the Company and the Trustee may amend this Indenture or the Notes
or may waive future compliance by the Company or any Subsidiary Guarantor with
any provisions of this Indenture, the Notes or such Subsidiary Guarantor's
Subsidiary Guaranty. However, without the consent of each Holder affected, a
waiver or an amendment to this Indenture or the Notes may not:

          (1) reduce the percentage of principal amount of the Notes whose
     Holders must consent to an amendment or waiver; or

          (2) make any change to the Stated Maturity of the principal of,
     premium, if any,


                                       67


<PAGE>   73



     or any interest on or Liquidated Damages, if any, with respect to, the
     Notes or any Redemption Price thereof, or impair the right to institute
     suit for the enforcement of any such payment or make any Note payable in
     money or securities other than that stated in the Note; or

          (3) waive a default in the payment of the principal of, premium, if
     any, interest on, or Liquidated Damages with respect to any Note;

          (4) release any Subsidiary Guarantor from any of its obligations under
     its Subsidiary Guaranty or the Indenture other than in compliance with the
     terms of the Indenture and such Subsidiary Guaranty; or

          (5) make any change in the provisions of Sections 4.11, 4.12, 6.04 or
     6.07 hereof; or

          (6) make any change to Section 9.01 or 9.02 hereof.

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

     In the event that certain Holders are willing to defer or waive certain
obligations of the Company hereunder with respect to Notes held by them, such
deferral or waiver shall not be deemed to affect any other Holder who receives
the subject payment or performance in a timely manner.

     After an amendment or waiver under this Section 9.02 becomes effective, the
Company shall mail to each Holder a notice briefly describing the amendment 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
amendment or waiver.

     SECTION 9.03 COMPLIANCE WITH TRUST INDENTURE ACT. Every supplemental
indenture executed pursuant to this Article 9 shall comply with the TIA.

     SECTION 9.04 REVOCATION AND EFFECT OF CONSENTS, WAIVERS AND ACTIONS. Until
an amendment, waiver or other action by Holders becomes effective, a consent to
it or any other action by a Holder of a Note hereunder is a continuing consent
by the Holder and every subsequent Holder of that Note or portion of the Note
that evidences the same obligation as the consenting Holder's Note, even if
notation of the consent, waiver or action is not made on the Note. However, any
such Holder or subsequent Holder may revoke the consent, waiver or action as to
such Holder's Note or portion of the Note if the Trustee receives the notice of
revocation before the consent of the requisite aggregate principal amount of the
Notes then outstanding has been obtained and not revoked. After an amendment,
waiver or action becomes effective, it shall


                                       68


<PAGE>   74


bind every Holder, except as provided in Section 9.02 hereof.

     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 or
waiver. If a record date is fixed, then, notwithstanding the first two 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. No such consent shall be valid or effective for more
than 90 days after such record date.

     SECTION 9.05 NOTATION ON OR EXCHANGE OF NOTES. Notes authenticated and made
available for delivery after the execution of any supplemental indenture
pursuant to this Article 9 may, and shall, if required by the Trustee, bear a
notation in form approved by the Trustee as to any matter provided for in such
supplemental indenture. If the Company shall so determine, new Notes so modified
as to conform, in the opinion of the Trustee and the Board of Directors of the
Company, to any such supplemental indenture may be prepared and executed by the
Company and authenticated and made available for delivery by the Trustee in
exchange for outstanding Notes.

     SECTION 9.06 TRUSTEE TO SIGN SUPPLEMENTAL INDENTURES. The Trustee shall
sign any supplemental indenture authorized pursuant to this Article 9 if the
supplemental indenture does not adversely affect the rights, duties, liabilities
or immunities of the Trustee. If it does, the Trustee may, but need not, sign
it. In signing such amendment the Trustee shall be entitled to receive, and
shall be fully protected in relying upon, an Officers' Certificate and Opinion
of Counsel stating that such supplemental indenture is authorized or permitted
by this Indenture.

     SECTION 9.07 EFFECT OF SUPPLEMENTAL INDENTURES. Upon the execution of any
supplemental indenture under this Article 9, this Indenture shall be modified in
accordance therewith, and such supplemental indenture shall form a part of this
Indenture for all purposes; and every Holder of Notes theretofore or thereafter
authenticated and made available for delivery hereunder shall be bound thereby.

                                  MISCELLANEOUS
                                  -------------

     SECTION 10.01 TRUST INDENTURE ACT CONTROLS. If any provision of this
Indenture limits, qualifies or conflicts with the duties imposed by operation of
subsection (c) of Section 318 of the TIA, the imposed duties shall control. The
provisions of Sections 310 to 317, inclusive, of the TIA that impose duties on
any Person (including provisions automatically deemed included in an indenture
unless the indenture provides that such provisions are excluded) are a part of
and govern this Indenture, except as, and to the extent, expressly excluded from
this Indenture, as permitted by the TIA.

its sufficiency with respect to other Holders. If a notice or communication is

     SECTION 10.08 LEGAL HOLIDAYS. A "Legal Holiday" is any day other than a
Business Day. If any specified date (including a date for giving notice) is a
Legal Holiday, the action shall be taken on the next succeeding day that is not

respect of the Notes, no principal, premium, if any, interest installment or
Liquidated Damages, if any, shall accrue for the intervening period.

State Street Bank and Trust Company,
   as Registrar
Attn: Corporate Trust Department


Dear Sirs:

     In connection with our proposed purchases of $         aggregate principal
amount of   % Series [A/B] Senior Notes due 2007 (the "Notes") of Nortek, Inc.
(the "Issuer"), a Delaware corporation, we confirm that:

     1. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act")) purchasing for our own account or for the account of such an
institutional "accredited investor," and we are acquiring the Notes for
investment purposes and not with a view to, or for offer or sale in connection
with, any distribution in violation of the Securities Act or the laws of any
state or other jurisdiction, and we have such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of our investment in the Notes, and we and any accounts for which we are
acting are each able to bear the economic risk of our or its investment.

     2. We understand that any subsequent transfer of the Notes is subject to
certain restrictions and conditions set forth in the Indenture relating to the
Notes (the "Indenture") and the undersigned agrees to be bound by, and not to
resell, pledge or otherwise transfer the Notes except in compliance with, such
restrictions and conditions of the Securities Act.

     3. We understand that the offer and sale of the Notes have not been
registered under the Securities Act, and that the Notes may not be offered or
sold except as described below. We agree, on our own behalf and on behalf of any
account for which we are purchasing the Notes, and each subsequent holder of the
Notes by its acceptance thereof will agree, not to offer, sell or otherwise
transfer such Notes prior to the date which is two years after the later of the
date of original issue of such Notes and the last date on which the Issuer or
any affiliate of the Issuer was the owner of such Notes (the "Resale Restriction
Termination Date"), except (A) to the Issuer, (B) in accordance with Rule 144A
under the Securities Act to


                                       C-1

<PAGE>   97



a "qualified institution buyer" (as defined therein) in a transaction meeting
the requirements of Rule 144A, (C) to an institutional "accredited investor" (as
defined above) that is purchasing for his own account or for the account of such
an "accredited investor" and that, prior to such transfer, furnishes to the
Trustee (as defined in the Indenture) a signed letter, substantially identical
to this letter, containing certain representations and agreements relating to
the restrictions on transfer of the Notes (the form of which letter can be
obtained from the Trustee), (D) pursuant to the exemption from registration
provided by Rule 144 under the Securities Act, if available, (E) pursuant to an
effective registration statement under the Securities Act, (F) outside the U.S.
to a foreign person in a transaction meeting the requirements of Regulation S
under the Securities Act, or (G) pursuant to any other available exemption from
the registration requirements of the Securities Act (based, in the cases of
clauses (C), (D), (F) and (G), upon an opinion of counsel reasonably acceptable
to the Issuer if the Issuer so requests), subject in each of the foregoing
cases, to any requirement of law that the disposition of our property or the
property of such investor account or accounts be at all times within our or
their control and to compliance with applicable securities laws of any state of
other jurisdiction. The foregoing restrictions on resale will not apply
subsequent to the Resale Restriction Termination Date, and we further agree to
provide to any person purchasing any of the Notes from us a notice advising such
purchaser that resales of the Notes are restricted as stated herein.

     4. We understand that, on any proposed offer, sale or other transfer of any
Notes prior to the Resale Restriction Termination Date, we will be required to
furnish to the Trustee and the Issuer such certifications, legal opinions, and
other information as either of them may reasonably require to confirm that the
proposed transaction complies with the foregoing restrictions. We further
understand that the Notes purchased by us will bear a legend reflecting the
substance of this and the preceding paragraph.

     5. We are acquiring the Notes purchased by us for our own account or for
one or more accounts (each of which is an institutional "accredited investor")
as to each of which we exercise sole investment discretion.

     We acknowledge that you, the Trustee and others are entitled to rely upon
this letter and are irrevocably authorized to produce this letter or a copy
thereof to any interested party in any administrative or legal proceedings or
official inquiry with respect to the matters covered hereby. We agree to notify
you promptly in writing if any of our representations or warranties ceases to be
accurate and complete.

     THIS LETTER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK.

                                   ARTICLE 11
                                GUARANTY OF NOTES
                                -----------------

     SECTION 11.01. SUBSIDIARY GUARANTY. Subject to the provisions of this
Article 11, each Subsidiary Guarantor hereby unconditionally guarantees to each
Holder of a Note authenticated and delivered by the Trustee and to the Trustee
that: (i) the principal of, premium, if any, interest on and Liquidated Damages,
if any, with respect to the Notes 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
Notes and all other obligations of the Company or the Subsidiary Guarantors to
the Holders or the Trustee hereunder or thereunder (including fees and expenses)
will be promptly paid in full or performed, all in accordance with the terms
hereof and thereof; and (ii) in case of any extension of time of payment or
renewal of any Notes or any such obligations with respect to the Notes, 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. This Subsidiary Guaranty is a present and continuing guaranty of
payment and performance, and not of collectibility. Accordingly, failing payment
when due of any amount so guaranteed, or failing performance of any other
obligation of the Company to the Holders under this Indenture or the Notes, for
whatever reason, each Subsidiary Guarantor shall be obligated to pay, or to
perform or cause the performance of, the same immediately.

     Each Subsidiary Guarantor hereby agrees that its obligations under its
Subsidiary Guaranty shall be absolute and unconditional, irrespective of any
invalidity, irregularity or unenforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder
of the Notes with respect to any provisions hereof or thereof, any release of
any other Subsidiary Guarantor or any other obligor under the Notes, the
recovery of any judgment against the Company, any action to enforce the same,
whether or not a Subsidiary Guaranty is affixed to any particular Note, or any
other circumstance which might otherwise constitute a legal or equitable
discharge or defense of a guarantor. Each Subsidiary Guarantor 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 or any other
obligor under the Notes, any right to require a proceeding first against the
Company or any such obligor, protest, notice and all demands whatsoever and
covenants that its Subsidiary Guaranty will not be discharged except by complete
performance the obligations contained in the Notes, this Indenture and its
Subsidiary Guaranty. 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, each Subsidiary Guaranty, to
the extent theretofore discharged, shall be reinstated in full force and effect.
Each Subsidiary


                                       E-1

<PAGE>   101



Guarantor further agrees that, as between it, on the one hand, and the Holders
of Notes and the Trustee, on the other hand, (i) subject to this Article 11, the
maturity of the obligations guaranteed hereby may be accelerated as provided in
Article 6 hereof for the purposes of each Subsidiary Guaranty, notwithstanding
any stay, injunction or other prohibition preventing such acceleration in
respect of the obligations guaranteed by this Subsidiary Guaranty, and (ii) in
the event of any acceleration of such obligations as provided in Article 6
hereof, such obligations (whether or not due and payable) shall forthwith become
due and payable by each Subsidiary Guarantor for the purpose of its Subsidiary
Guaranty. Upon the effectiveness of any acceleration of the obligations
guaranteed by this Subsidiary Guaranty the Trustee shall promptly make a demand
for payment of such obligations by each Subsidiary Guarantor under this
subsidiary Guaranty. The obligations of the Subsidiary Guarantors under this
Subsidiary Guaranty shall be joint and several.

     Each Subsidiary Guaranty 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 Notes are,
pursuant to applicable law, rescinded, or reduced in amount, or must otherwise
be restored or returned by any obligee on the Notes, 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 Notes 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, of any Subsidiary Guarantor, as such, shall have any personal
liability under such Subsidiary Guarantor's Subsidiary Guaranty 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 any Subsidiary Guaranty.

     Each Subsidiary Guaranty may be modified from time to time, without the
consent of the Holders, to reflect such fraudulent conveyance savings
provisions, net worth or maximum amount limitations as to recourse or similar
provisions as are set forth in, and after giving effect to, any guaranty by any
Subsidiary Guarantor of any Senior Indebtedness with respect to the Company
Credit Facility as such guaranty may be amended or otherwise modified from time
to time, PROVIDED that no such modification of this Subsidiary Guaranty shall
adversely affect the Holders in any respect or shall disadvantage the Holders
relative to the holders of Indebtedness of such Subsidiary Guarantor with
respect to the Company Credit Facility.

     SECTION 11.02. EXECUTION DELIVERY OF SUBSIDIARY GUARANTY. The validity and
enforceability of this Subsidiary Guaranty shall not be affected by the fact
that it is not affixed to any particular Note, and each Subsidiary Guarantor
hereby agrees that its Subsidiary Guaranty shall remain in full force and effect
notwithstanding any failure to endorse on each Note a notation of such
Subsidiary Guaranty.

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

     The delivery by any Subsidiary Guarantor to the Trustee of any Subsidiary
Guaranty as required by Section 4.14 shall constitute due delivery of such
Subsidiary Guaranty on behalf of such Subsidiary Guarantor to and for the
benefit of all Holders of the Notes.

     SECTION 11.03. ADDITIONAL GUARANTORS. Any person may become a guarantor of
the Notes by executing and delivering to the Trustee (i) a supplemental
indenture in form and substance satisfactory to the Trustee, which subjects such
person to the provisions of this Indenture as a guarantor of the Notes, and (ii)
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 11.04. RELEASE OF SUBSIDIARY GUARANTOR. Notwithstanding anything to
the contrary contained in this Indenture in the event that Section 4.14 of the
Indenture ceases to have further force or effect each Subsidiary Guarantor shall
be, and in the event a Subsidiary Guarantor is released from all obligations
which pursuant to Section 4.14 hereof obligate it to become a Subsidiary
Guarantor such Subsidiary Guarantor shall be, deemed automatically and
unconditionally released from all obligations under its Subsidiary Guaranty
without any further action required on the part of the Trustee or any Holder,
PROVIDED that, to the extent the provisions of Section 4.14 remain in force and
effect, the provisions of Section 4.14 hereof shall apply anew in the event that
such Subsidiary Guarantor subsequent to being released incurs any obligations
that pursuant to Section 4.14 hereof obligate it to become a Subsidiary
Guarantor. In addition, upon (i) the designation of any Subsidiary Guarantor as
an Unrestricted Subsidiary in compliance with the terms of the Indenture or (ii)
the sale or other disposition of all of the Capital Stock of a Subsidiary
Guarantor by the Company or a Subsidiary of the Company to, or upon the
consolidation or merger of a Subsidiary Guarantor with or into, any person other
than the Company or an Affiliate of the Company or any of its Subsidiaries, such
Subsidiary Guarantor shall be deemed automatically and unconditionally released
from all obligations under its Subsidiary Guaranty without any further action
required on the part of the Trustee or any Holder, PROVIDED that such sale or
other disposition, or consolidation or merger is made in accordance with the
terms of this Indenture, including


                                       E-3

<PAGE>   103



Sections 4.12 and 5.01 hereof; PROVIDED, HOWEVER, that the foregoing proviso
shall not apply to the sale or disposition of a subsidiary Guarantor or of the
Capital Stock thereof in a foreclosure proceeding (whether or not judicial) to
the extent that such proviso would be inconsistent with the requirements of the
Uniform Commercial Code. Notwithstanding the immediately preceding sentence,
upon receipt of a request of the Company accompanied by an Officers' Certificate
certifying as to the compliance with this Section 11.04, the Trustee shall
deliver an appropriate instrument evidencing the release of such Subsidiary
Guarantor. Any Subsidiary Guarantor not so released or the entity surviving such
Subsidiary Guarantor, as applicable, shall remain or be liable under its
Subsidiary Guaranty as provided in this Article 11.

Damages, if any, of such Note, if lawful, and the payments or performance of all
other obligations of the Company under the Indenture or the Notes, all in
accordance with and subject to the terms and limitations of such Note, Article
11 of the Indenture and this Guaranty. This Guaranty shall become effective in
accordance with Article 11 of the Indenture. The validity and enforceability of
this Guaranty shall not be affected by the fact that it is not affixed to any
particular Note.

     The obligations of the undersigned to the holders of Notes and to the
Trustee pursuant to this Guaranty and the Indenture are expressly set forth in
Article 11 of the Indenture and reference is hereby made to the Indenture for
the precise terms of this Guaranty and all of the other provisions of the
Indenture to which this Guaranty relates. Each holder of a Note, by accepting
the same, agrees to and shall be bound by such provisions.

     This Guaranty is subject to release upon the terms set forth in the
Indenture.

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

          (a) EXCHANGE OFFER. To the extent not prohibited by any applicable law
or applicable interpretation of the staff of the Commission, the Company shall,
for the benefit of the Holders, at the Company's cost, use its best efforts to
cause to be filed with the Commission an Exchange Offer Registration Statement
on or prior to 45 days after the Closing Date on an appropriate form under the
Act covering the offer by the Company to the Holders to exchange all of the
Registrable Securities (other than Private Exchange Notes) for a like aggregate
principal amount of Exchange Notes, to cause such Exchange Offer Registration
Statement to be declared effective under the Act by the Commission on or prior
to 120 days after the Closing Date, to cause such Registration Statement to
remain effective until the closing of the Exchange Offer and to cause the
Exchange Offer to be consummated on or prior to 45 days after the date on which
the Exchange Offer Registration Statement was declared effective under the Act
by the Commission. The Exchange Notes will be issued under the Indenture. Upon
the effectiveness of the Exchange Offer Registration Statement, the Company
shall promptly commence the Exchange Offer, it being the objective of such
Exchange Offer to enable each Holder (other than Participating Broker-Dealers
(as defined in Section 3(t) hereof)) eligible and electing to exchange
Registrable Securities for Exchange Notes (assuming that such Holder is not an
affiliate of the Company within the meaning of Rule 405 under the Act, acquires
the Exchange Notes in the ordinary course of such Holder's business and has no
arrangements or understandings with any Person to participate in the Exchange
Offer for the purpose of distributing the Exchange Notes) to transfer such
Exchange Notes from and after their receipt without any limitations or
restrictions under the Act or under state securities or blue sky laws.

          In connection with the Exchange Offer, the Company shall:

          (i) mail to each Holder a copy of the Prospectus forming part of the
     Exchange Offer Registration Statement together with an appropriate letter
     of transmittal and related documents;



                                       5
<PAGE>   6


          (ii)  keep the Exchange Offer open for acceptance for a period of not
     less than 30 days after the date notice thereof is mailed to the Holders,
     or longer if required by applicable law (such period being referred to
     herein as the "EXCHANGE PERIOD");

          (iii) utilize the services of the Depository for the Exchange Offer;

          (iv)  permit Holders to withdraw tendered Notes at any time prior to
     the close of business, New York City time, on the last business day of the
     Exchange Period, by sending to the institution specified in the notice a
     telegram, telex, facsimile transmission or letter setting forth the name of
     such Holder, the principal amount of Notes delivered for exchange, and a
     statement that such Holder is withdrawing its election to have such Notes
     exchanged;

          (v)   notify each Holder that any Note not tendered will remain
     outstanding and continue to accrue interest, but will not retain any rights
     under this Agreement (except in the case of the Initial Purchasers and
     Participating Broker-Dealers as provided herein); and

          (vi)  otherwise comply in all respects with all applicable laws
     relating to the Exchange Offer.

          If, prior to consummation of the Exchange Offer, any 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 Notes in the Exchange
Offer, issue and deliver to such Initial Purchaser in exchange (the "PRIVATE
EXCHANGE") for Notes held by the Initial Purchasers a like principal amount of
debt securities of the Company that are identical (except that such securities
shall bear appropriate transfer restrictions) to the Exchange Notes (the
"PRIVATE EXCHANGE NOTES") and which are issued pursuant to the Indenture (which
will provide that the Exchange Notes will not be subject to the transfer
restrictions set forth in the Indenture and that the Exchange Notes, the Private
Exchange Notes and the Notes will vote and consent together on all matters as
one class and that none of the Exchange Notes, the Private Exchange Notes or the
Notes will have the right to vote or consent as a separate class on any matter).
The Private Exchange Notes shall be of the same series as and shall bear the
same CUSIP number as the Exchange Notes.

          As soon as practicable after the close of the Exchange Offer or the 
Private Exchange, as the case may be, the Company shall;

          (i) accept for exchange all Notes or portions thereof duly tendered
     and not validly withdrawn pursuant to the Exchange Offer;



                                       6
<PAGE>   7


          (ii)  accept for exchange all Notes or portions thereof duly tendered
     pursuant to the Private Exchange; and

          (iii) deliver, or cause to be delivered, to the Trustee for
     cancellation all Notes or portions thereof so accepted for exchange by the
     Company, and issue, and cause the Trustee to promptly authenticate and
     deliver to each Holder, a new Exchange Note or Private Exchange Note, as
     the case may be, equal in principal amount to the principal amount of the
     Notes surrendered by such Holder.

          To the extent not prohibited by applicable law or any applicable
interpretation of the staff of the Commission, the Company shall use its best
efforts to complete the Exchange Offer as provided above, and shall comply with
all applicable requirements of the Act, the Exchange Act and other applicable
laws in connection with the Exchange Offer. The Exchange Offer shall not be
subject to any condition, other than that (i) the Exchange Offer does not
violate any applicable law or interpretation of the staff of the Commission,
(ii) no action or proceeding has been instituted or threatened in any court or
by or before any governmental agency with respect to the Exchange Offer which,
in the reasonable judgment of the Company, might impair the ability of the
Company to proceed with the Exchange Offer, (iii) there has not been any
material change, or development involving a prospective material change, in the
business or financial affairs of the Company or any of its subsidiaries which,
in the reasonable judgment of the Company, would materially impair the Company's
ability to consummate the Exchange Offer or have a material adverse effect on
the Company if the Exchange Offer is consummated, (iv) there has not been
proposed, adopted, or enacted any law, statute, rule or regulation which, in the
reasonable judgment of the Company, might materially impair the ability of the
Company to proceed with the Exchange Offer or have a material adverse effect on
the Company if the Exchange Offer is consummated or (v) all governmental
approvals which the Company shall reasonably deem necessary for the consummation
of the Exchange Offer as contemplated shall have been obtained. Each Holder of
Registrable Securities who wishes to exchange such Registrable Securities for
Exchange Notes in the Exchange Offer will be required to make certain customary
representations in connection therewith, including representations that such
Holder is not an affiliate of the Company within the meaning of Rule 405 under
the Act, that any Exchange Notes to be received by it will be acquired in the
ordinary course of business and that at the time of the commencement of the
Exchange Offer it had no arrangement with any Person to participate in the
distribution (within the meaning of the Act) of the Exchange Notes and will be
required to make such other representations as may be necessary under applicable
Commission rules, regulations or interpretations to render available the use of
Form S-4 or any other appropriate form under the Act. The Company shall inform
the Initial Purchasers, after consultation with the Trustee and the Initial
Purchasers, of the names and addresses of the Holders to whom the Exchange Offer
is made, and the Initial Purchasers shall have the right to contact such Holders
and otherwise facilitate the tender of Registrable Securities in the Exchange
Offer.



                                       7
<PAGE>   8



          In the event that the Company is unable to consummate the Exchange 
Offer due to any event listed in clauses (i) through (v) in the paragraph
immediately above, the Company shall not be deemed to have breached any covenant
under this Section 2(a).

          Upon consummation of the Exchange Offer in accordance with this 
Section 2(a), the provisions of this Agreement shall continue to apply, MUTATIS
MUTANDIS, solely with respect to Registrable Securities that are Private
Exchange Notes and Exchange Notes held by Participating Broker-Dealers, and the
Company shall have no further obligation to register Registrable Securities
(other than Private Exchange Notes) pursuant to Section 2(b) of this Agreement.

          (b) SHELF REGISTRATION. In the event that (i) the Company is not 
permitted to commence or accept tenders pursuant to the Exchange Offer because
the Exchange Offer is not permitted by applicable law or Commission policy, (ii)
any Holder of Transfer Restricted Securities notifies the Company within 20
business days after the consummation of the Exchange Offer that (a) it is
prohibited by law or Commission policy from participating in the Exchange Offer,
(b) that it may not resell the Exchange Notes acquired by it in the Exchange
Offer to the public without delivering a prospectus and the prospectus contained
in the Exchange Offer Registration Statement is not appropriate or available for
such resales or (c) that it is a broker-dealer and owns Notes acquired directly
from the Company or an affiliate of the Company, or (iii) the Exchange Offer is
not for any other reason consummated within 165 days of the Closing Date, the
Company shall, at its cost, cause to be filed with the Commission as promptly as
practicable after such determination or date, as the case may be, and, in any
event, on or prior to 45 days thereafter, a Shelf Registration Statement
providing for the sale by the Holders of all of the Registrable Securities, and
shall use its best efforts to cause such Shelf Registration Statement declared
effective by the Commission on or prior to 90 days after such determination or
date. No Holder of Registrable Securities may include any of its Registrable
Securities in any Shelf Registration pursuant to this Agreement unless and until
such Holder furnishes to the Company in writing, within 15 days after receipt of
a request therefor, such information as the Company may, after conferring with
counsel with regard to information relating to Holders that would be required by
the Commission to be included in such Shelf Registration Statement or Prospectus
included therein, reasonably request for inclusion in any Shelf Registration
Statement or Prospectus included therein. Each Holder as to which any Shelf
Registration is being effected agrees to furnish promptly to the Company all
information required to be disclosed in the applicable Shelf Registration
Statement or Prospectus included therein by the rules and regulations of the
Commission applicable to the Shelf Registration Statement in order to make the
information previously furnished to the Company by such Holder not materially
misleading.

          The Company agrees, subject to applicable law or applicable 
interpretation of the staff of the Commission, to use its reasonable best
efforts to keep the Shelf Registration Statement continuously effective,
supplemented and amended under the Act for a period ending on the earlier of the
date which is two years from the Closing Date (subject



                                       8
<PAGE>   9



to extension pursuant to the last paragraph of Section 3) or the date on which
all of the Registrable Securities covered by the Shelf Registration Statement
have been sold pursuant to the Shelf Registration Statement or cease to be
outstanding (the "EFFECTIVENESS PERIOD"). The Company shall not permit any
securities other than Registrable Securities to be included in the Shelf
Registration. The Company will, in the event a Shelf Registration Statement is
declared effective, provide to each Holder 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 customary to permit unrestricted resales of the Registrable Securities
covered by the Shelf Registration Statement. The Company further agrees, if
necessary, to use its reasonable best efforts to supplement or amend the Shelf
Registration Statement, if required by the Act or the rules, regulations or
instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or by any other rules and regulations thereunder
for shelf registrations, or if reasonably requested by the Majority Holders, and
the Company agrees to furnish to the Holders copies of any such supplement or
amendment promptly after its being used or filed with the Commission.

          (c) EXPENSES. The Company shall pay all Registration Expenses in 
connection with registrations pursuant to Section 2(a) or 2(b). Each Holder
shall pay all expenses of its counsel (other than the fees described in clauses
(i) and (ii) of the definition of "Registration Expenses"), underwriting
discounts and commissions and transfer taxes, if any, relating to the sale or
disposition of such Holder's Registrable Securities pursuant to the Exchange
Offer Registration Statement and the Shelf Registration Statement.

          (d) EFFECTIVE REGISTRATION STATEMENT. An Exchange Offer Registration
Statement pursuant to Section 2(a) hereof or a Shelf Registration Statement
pursuant to Section 2(b) hereof will not be deemed to have become effective
unless it has been declared effective by the Commission; PROVIDED, HOWEVER, that
if, after it has been declared effective, the offering of Registrable Securities
pursuant to a Shelf Registration Statement is interfered with by any stop order,
injunction or other order or requirement of the Commission or any other
governmental agency or court, such Registration Statement will be deemed not to
have been effective during the period of such interference, until the offering
of Registrable Securities pursuant to such Registration Statement may legally
resume.

          (e) LIQUIDATED DAMAGES. In the event that an Exchange Offer 
Registration Statement has not been filed with the Commission on or prior to 45
days after the Closing Date, additional interest payable by the Company as
liquidated damages ("LIQUIDATED DAMAGES") will accrue on the Notes from and
including the 31st day after the Closing Date until but excluding the date such
Exchange Offer Registration Statement is filed. In addition, if on or prior to
120 days after the Closing Date, such Exchange Offer Registration Statement is
not declared effective under the Act by the Commission, Liquidated Damages will
accrue on the Notes from and including the 121st day after the Closing Date
until but excluding the date such Exchange Offer Registration Statement is
declared effective. Further, if on or prior to 45 days after the date specified
for effectiveness of the Exchange Offer Registration



                                       9
<PAGE>   10



Statement the Exchange Offer is not consummated, Liquidated Damages will accrue
on the Notes from and including the 46th day after the date specified for
effectiveness of the Exchange Offer Registration Statement, but excluding, the
consummation of the Exchange Offer. If a Shelf Registration Statement is
required to be filed pursuant to Section 2(b) and such Shelf Registration
Statement is not filed or declared effective within the time periods provided by
Section 2(b) hereof for such filing or declaration, Liquidated Damages will
accrue on the Notes (other than those exchanged in the Exchange Offer) or the
Private Exchange Notes, as the case may be, from and including the day
immediately following such default until but excluding the effective date of the
Shelf Registration Statement. Further, if the Shelf Registration Statement or
the Exchange Offer Registration Statement is declared effective but thereafter
ceases to be effective or usable during the time periods specified in this
Agreement, Liquidated Damages will accrue on the Notes (other than those
exchanged in the Exchange Offer) or the Private Exchange Notes, as the case may
be, from and including the day immediately following such default until but
excluding the date such Registration Statement becomes effective or usable. In
each case, such Liquidated Damages will be payable in cash semiannually in
arrears, with the first semiannual payment due on the first interest payment
date in respect of the Notes (or the Private Exchange Notes) following the date
from which Liquidated Damages begin to accrue, and will accrue, under each
circumstance set forth above at a rate per annum equal to an additional one half
of one percent (0.50%) of the principal amount of the Notes (or the Private
Exchange Notes) upon the occurrence of each such circumstance, which rate will
increase by one half of one percent (0.50%) for each 90-day period that such
Liquidated Damages continue to accrue under any circumstance, with an aggregate
maximum increase in the interest rate per annum equal to two percent (2.00%).

          Upon the filing of the Exchange Offer Registration Statement, the
effectiveness of the Exchange Offer Registration Statement, or the consummation
of the Exchange Offer, as the case may be, the interest rate borne by the Notes
will be reduced by the full amount of any such increase to the extent that such
increase related to the failure of any such event to have occurred. Upon the
effectiveness of a Shelf Registration Statement, the interest rate borne by the
Notes (and the Private Exchange Notes) shall be reduced, from and as of the date
of such effectiveness, to the original interest rate of the Notes unless and
until increased as described above. Notwithstanding anything to the contrary
contained herein, the Company (i) shall not be required to amend or supplement
the Shelf Registration Statement, any related prospectus or any document
incorporated therein by reference and (ii) may suspend the effectiveness of any
such Shelf Registration Statement in the event that, and for a period not to
exceed, for so long as this Agreement is in effect, an aggregate of 90 days in
any one calendar year if (A) an event occurs and is continuing as a result of
which the Shelf Registration Statement, any related prospectus or any document
incorporated therein by reference as then amended or supplemented would, in the
Company's good faith judgment, contain an untrue statement of a material fact or
omit to state a material fact necessary in order to make the statements therein
not misleading, and (B) the Company determines in its good faith judgment that
the disclosure of such event at such time would have a material adverse effect
on the business, operations or prospects of the Company;



                                       10
<PAGE>   11



provided that any such suspension shall not relieve the Company from its
obligation to pay Liquidated Damages.

          The Company shall notify the Trustee within three business days after
each and every date on which an event occurs in respect of which Liquidated
Damages is required to be paid (an "EVENT DATE"). Liquidated Damages shall be
paid by depositing with the Trustee, in trust, for the benefit of the Holders of
Notes, Exchange Notes or Private Exchange Notes, as the case may be, on or
before the applicable semiannual interest payment date, immediately available
funds in sums sufficient to pay the Liquidated Damages then due. The Liquidated
Damages due shall be payable on each interest payment date to the record Holder
of Notes entitled to receive the interest payment to be paid on such date as set
forth in the Indenture. Each obligation to pay Liquidated Damages shall be
deemed to accrue from and including the day following the applicable Event Date.

          (f) SPECIFIC ENFORCEMENT. Without limiting the remedies available to 
the Initial Purchasers and the Holders, the Company acknowledges that any
failure by the Company to comply with its obligations under Section 2(a) and
Section 2(b) hereof would result in material irreparable injury to the Initial
Purchasers or the Holders for which there is no adequate remedy at law, that it
would not be possible to measure damages for such injuries precisely and that,
in the event of any such failure, the Initial Purchasers or any Holder may
obtain such relief as may be required to specifically enforce the Company's
obligations under Section 2(a) and Section 2(b) hereof.

          3. REGISTRATION PROCEDURES. In connection with the obligations of the
Company with respect to the Registration Statements pursuant to Sections 2(a)
and 2(b) hereof, the Company shall:

          (a) prepare and file with the Commission a Registration Statement or
     Registration Statements as prescribed by Sections 2(a) and 2(b) within the
     relevant time periods specified in Section 2 hereof on the appropriate form
     under the Act, which form (i) shall be selected by the Company, (ii) shall,
     in the case of a Shelf Registration, be available for the sale of the
     Registrable Securities by the selling Holders and (iii) shall comply as to
     form in all material respects with the requirements of the applicable form
     and include or incorporate by reference all financial statements required
     by the Commission to be filed therewith, and the Company shall use its best
     efforts to cause such Registration Statement to become effective and remain
     effective in accordance with Section 2; PROVIDED, HOWEVER that if (1) such
     filing is pursuant to Section 2(b), or (2) a Prospectus contained in an
     Exchange Offer Registration Statement filed pursuant to Section 2(a) is
     required to be delivered under the Act by any Participating Broker-Dealer
     who seeks to sell Exchange Notes, before filing any Registration Statement
     or Prospectus or any amendments or supplements thereto, the Company, if
     requested, shall furnish to and afford the Holders 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

     documents to be incorporated by reference therein and all exhibits thereto)

     Company shall not file any Registration Statement or Prospectus or any
     amendments or supplements thereto in respect of which the Holders, pursuant
     to this Agreement, must be afforded an opportunity to review prior to the
     filing of such document, if the Majority Holders or such Participating
     Broker-Dealer, as the case may be, their counsel or the managing
     underwriters, if any, shall reasonably object;

          (b) subject to Section 3(a) hereof, prepare and file with the
     Commission such amendments and post-effective amendments to each
     Registration Statement as may be necessary to keep such Registration
     Statement effective for the Effectiveness Period or the Applicable Period.
     as the case may be, and cause each Prospectus to be supplemented by any
     required prospectus supplement and as so supplemented to be filed pursuant
     to Rule 424 (or any similar provision then in force) under the Act, and
     comply with the provisions of the Act, the Exchange Act and the rules and
     regulations promulgated thereunder applicable to it with respect to the
     disposition of all securities covered by each Registration Statement during
     the Effectiveness Period or the Applicable Period, as the case may be, in
     accordance with the intended method or methods of distribution by the
     selling Holders thereof described in this Agreement (including sales by any
     Participating Broker-Dealer);

          (c) in the case of a Shelf Registration, (i) notify each Holder, at
     least five business days prior to filing, that a Shelf Registration

     underwriter may reasonably request, in order to facilitate the public sale
     or other disposition of the Registrable Securities, and (iii) subject to
     the last paragraph of this Section 3, consent to the use of the Prospectus
     or any amendment or supplement thereto by each of the selling Holders in
     connection with the offering and sale of the Registrable Securities covered
     by the Prospectus or any amendment or supplement thereto, provided that
     such use complies with all applicable laws and regulations;

          (d) use its best efforts to register or qualify the Registrable
     Securities under all applicable state securities or "blue sky" laws of such
     jurisdictions as any Holder of Registrable Securities covered by a
     Registration Statement and each underwriter of an underwritten offering of
     Registrable Securities shall reasonably request by the time the applicable
     Registration Statement is declared effective by the Commission, and do any
     and all other acts and things which may be reasonably necessary or
     advisable to enable such Holder and underwriter to consummate the dis-



                                       12

     position in each such jurisdiction of such Registrable Securities owned by
     such Holder; PROVIDED, HOWEVER, that the Company shall not be required to
     (i) qualify as a foreign partnership or foreign corporation or as a dealer
     in securities in any jurisdiction where it would not otherwise be required
     to qualify but for this Section 3(d), (ii) file any general consent to
     service of process in any jurisdiction where it would not otherwise be

     Broker-Dealers who have notified the Company that they will be utilizing
     the Prospectus contained in the Exchange Offer Registration Statement as
     provided in Section 3(t) hereof, are seeking to sell Exchange Notes and are
     required to deliver Prospectuses, notify each Holder, or such Participating
     Broker-Dealers, as the case may be, their counsel and the managing
     underwriters, if any, promptly and, if requested by such Holder or
     Participating Broker-Dealer, confirm such notice in writing (i) when a
     Registration Statement has become effective and when any post-effective
     amendments and supplements thereto become effective, (ii) of any request by
     the Commission or any state securities authority for amendments and
     supplements to a Registration Statement or Prospectus or for additional

     stop order suspending the effectiveness of a Registration Statement or the
     initiation of any proceedings for that purpose, (iv) in the case of a Shelf

     relating to such offering cease to be true and correct in all material
     respects, (v) if the Company receives any notification with respect to the
     suspension of the qualification of the Registrable Securities or the
     Exchange Notes to be sold by any Participating Broker-Dealer for offer or
     sale in any jurisdiction or the initiation of any proceeding for such
     purpose, (vi) of the happening of any event or the failure of any event to
     occur or the discovery of any facts or otherwise, during the period a Shelf

     may be, which makes any statement made in the Shelf Registration Statement,
     the Exchange Offer Registration Statement or any related Prospectus untrue
     in any material respect or which causes such Registration Statement or

     Exchange Notes or the Private Exchange Notes, as the case may be, the
     Company shall mark, or cause to be marked, on such Registrable Securities
     delivered by such Holders that such Registrable Securities are being

     Initial Purchasers or another representative of the Participating
     Broker-Dealers, and which shall contain a summary statement of the
     positions taken or policies made by the staff of the Commission with
     respect to the potential "underwriter" status of any broker-dealer (a
     "PARTICIPATING BROKER-DEALER") that holds Registrable Securities acquired
     for its own account as a result of market-making activities or other
     trading activities and that will be the beneficial owner (as defined in
     Rule 13d-3 under the Exchange Act) of Exchange Notes to be received by such
     broker-dealer in the Exchange Offer, whether such positions or policies
     have been publicly disseminated by the staff of the Commission or such
     positions or policies, in the reasonable judgment of the Initial Purchasers
     or such other representative, represent the prevailing views of the staff
     of the Commission, including a statement that any such broker-dealer who

     Offer may be deemed a statutory underwriter and must deliver a prospectus
     meeting the requirements of the Act in connection with any resale of such
     Exchange Notes, (ii) furnish to each Participating Broker-Dealer who has

     preliminary prospectus, and any amendment or supplement thereto, as such
     Participating Broker-Dealer may reasonably request, (iii) subject to the
     last paragraph of this Section 3, hereby consent to the use of the
     Prospectus forming part of the Exchange Offer Registration Statement or any
     amendment or supplement thereto, by any Person subject to the prospectus
     delivery requirements of the Commission, including all Participating
     Broker-Dealers, in connection with the sale or transfer of the Exchange
     Notes covered by the Prospectus or any amendment or supplement thereto,
     (iv) use its best efforts to keep the Exchange Offer 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 Act for such period
     of time as such Persons must comply with such requirements in order to
     resell the Exchange Notes (PROVIDED, HOWEVER, that such period shall not be
     required to exceed 180 days, or such longer period if extended pursuant to
     the last sentence of this Section 3 (the "APPLICABLE PERIOD")), and (v)
     include in the transmittal letter or similar documentation to be executed
     by an exchange offeree all necessary information for such offeree to
     participate in the Exchange Offer;

          (B) in the case of any Exchange Offer Registration Statement, the
     Company agrees to deliver to the Initial Purchasers or to another
     representative of the Participating Broker-Dealers on behalf of the
     Participating Broker-Dealers upon consummation of the Exchange Offer (i) an
     opinion of counsel substantially in the form attached hereto as EXHIBIT A,
     (ii) an Officers' Certificate containing certifications substantially
     similar to those set forth in Section 8(d) of the Purchase Agreement and
     such additional certifications as are customarily delivered in a public
     offering of debt securities, and (iii) a comfort letter in customary form
     permitted by Statement of Auditing Standards No. 72 of the American
     Institute of Certified Public Accountants.

          The Company may require each seller of Registrable Securities as to 
which any registration is being effected to furnish to the Company such
information regarding such seller and the proposed distribution of such
Registrable Securities as the Company may from time to time reasonably request
in writing. The Company may exclude from such registration the Registrable
Securities of any seller who unreasonably fails to furnish such information
within a reasonable time after receiving such request.

          In the case of (i) a Shelf Registration Statement or (ii) 
Participating Broker-Dealers who have notified the Company that they will be
utilizing the Prospectus contained in the Exchange Offer Registration Statement
as provided in Section 3(t) hereof, are seeking to sell Exchange Notes and are
required to deliver copies of such Prospectus, each Holder agrees that, upon
receipt of any notice from the Company of the happening of any event of the kind
described in Section 3(e)(ii), 3(e)(iii), 3(e)(iv), 3(e)(v), 3(e)(vi) or
3(e)(vii) hereof, such Holder will forthwith discontinue disposition of
Registrable Securities


                                       18
<PAGE>   19



pursuant to a Registration Statement until such Holder's receipt of the copies
of the supplemented or amended Prospectus contemplated by Section 3(i) hereof or
until it is advised in writing by the Company that the use of the applicable
Prospectus may be resumed, and, if so directed by the Company, such Holder will
deliver to the Company (at the Company's expense) all copies in such Holder's
possession, other than permanent file copies then in such Holder's possession,
of the Prospectus covering such Registrable Securities or Exchange Notes, as the
case may be, current at the time of receipt of such notice. If the Company shall
give any such notice to suspend the disposition of Registrable Securities or
Exchange Notes, as the case may be, pursuant to a Registration Statement, the
Company shall use its best efforts to file and have declared effective (if an
amendment) as soon as practicable an amendment or supplement to the Registration
Statement and shall extend the period during which such Registration Statement
shall be maintained effective pursuant to this Agreement by the number of days
in the period from and including the date of the giving of such notice to and
including the date when the Company shall have made available to the Holders
copies of the supplemented or amended Prospectus necessary to resume such
dispositions or shall have advised the Holders in writing that the use of the
applicable Prospectus may be resumed.

          4. INDEMNIFICATION AND CONTRIBUTION. (a) The Company shall indemnify 
and hold harmless the Initial Purchasers, each Holder, each Participating
Broker-Dealer, each underwriter who participates in an offering of Registrable
Securities, each of their respective affiliates, each Person, if any, who
controls any of such parties within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, and each of their respective directors,
officers, partners, employees, representatives and agents, to the fullest extent
lawful as follows:

          (i) from and against any and all loss, liability, claim, damage and
     expense whatsoever, joint or several, as incurred, arising out of any
     untrue statement or alleged untrue statement of a material fact contained
     in any Registration Statement or any amendment thereto pursuant to which
     the offer and sale of the Registrable Securities or Exchange Notes were
     registered under the Act including all documents incorporated therein by
     reference, or the omission or alleged omission therefrom of a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, or arising out of any untrue statement or alleged untrue
     statement of a material fact contained in any Prospectus or any amendment
     or supplement thereto. or the omission or alleged omission therefrom of a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

          (ii) from and against any and all loss, liability, claim, damage and
     expense whatsoever, joint or several, to the extent of the aggregate amount
     paid in settlement of any litigation, or any investigation or proceeding by
     any court or governmental agency or body, ,whether commenced or threatened,
     or any claim whatsoever based upon any such untrue statement or omission,
     or any such alleged untrue statement or



                                       19
<PAGE>   20



     omission, if and only if such settlement is effected with the prior written
     consent of the Company; and

          (iii) from and against any and all expenses whatsoever (including
     reasonable fees and disbursements of counsel chosen by the Initial
     Purchasers, Holder, Participating Broker-Dealer or underwriter (except to
     the extent otherwise expressly provided in Section 4(c) hereof)), as
     incurred, reasonably incurred in investigating, preparing for or defending
     against any litigation. or any investigation or proceeding by any court or
     governmental agency or body. whether commenced or threatened, or any other
     claim whatsoever based upon any such untrue statement or omission, or any
     such alleged untrue statement or omission, to the extent that any such
     expense is not paid under subparagraph (i) or (ii) of this Section 4(a);

PROVIDED, HOWEVER, that this indemnity does not apply to any loss, liability,
claim, damage or expense to the extent arising out of an untrue statement or
omission or alleged untrue statement or omission (i) made solely in reliance
upon and in conformity with written information furnished to the Company by the
Initial Purchasers, such Holder, such Participating Broker-Dealer or any
underwriter in writing expressly for use in the Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto) or
(ii) contained in any preliminary prospectus or any Prospectus if the Initial
Purchasers, such Holder, such Participating Broker-Dealer or such underwriter
failed to send or deliver a copy of the Prospectus (as then amended or
supplemented if the Company shall have timely furnished any amendments or
supplements thereto) to the Person asserting such losses, liabilities. claims or
damages on or prior to the-delivery of written confirmation of any sale of
securities covered thereby to such Person in any case where such delivery is
required by the Act and such Prospectus (as so amended or supplemented) would
have corrected such untrue statement or omission and the delivery thereof would
have eliminated such losses, claims, damages or liabilities. Any amounts
advanced by the Company to an indemnified party pursuant to this Section 4 as a
result of such losses shall be returned to the Company if it shall be determined
by a court that such indemnified party was not entitled to indemnification by
the Company.

          (b) Each Holder agrees, severally and not jointly, to indemnify and 
hold harmless the Company, the Initial Purchasers, each underwriter who
participates in an offering of Registrable Securities and the other selling
Holders and each of their respective directors, officers (including each officer
of the Company who signed the Registration Statement), employees,
representatives and agents, and each Person, if any, who controls the Company,
the Initial Purchasers, any underwriter or any other selling Holder within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and
against any and all loss, liability, claim, damage and expense whatsoever
described in the indemnity contained in Section 4(a) hereof, as reasonably
incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions. made in the Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto)
solely in reliance upon and in conformity with written information furnished to
the


                                       20
<PAGE>   21



Company by such selling Holder expressly for use in the Registration Statement
(or any amendment thereto) or any such Prospectus (or any amendment or
supplement thereto); PROVIDED, HOWEVER, that, in the case of a Shelf
Registration Statement, no such Holder shall be liable for any claims hereunder
in excess of the amount of net proceeds received by such Holder from the sale of
Registrable Securities pursuant to such Shelf Registration Statement.

          (c) Each indemnified party shall give prompt notice to each 
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, enclosing a copy of all papers properly
served on such indemnified party (but failure to notify an indemnifying party
shall not relieve such indemnifying party from any liability hereunder to the
extent it is not materially prejudiced as a result thereof and in any event
shall not relieve it from any liability which it may have other than on account
of this indemnity agreement). An indemnifying party may participate, at its own
expense, in the defense of any such action. If an indemnifying party so elects
within a reasonable time after receipt of such notice, such indemnifying party,
jointly with any other indemnifying party. may assume the defense of such action
with counsel chosen by it and reasonably satisfactory to the indemnified parties
defendant in such action; PROVIDED, HOWEVER, that if any such indemnified party
reasonably determines, upon written advice of counsel, that there may be legal
defenses available to such indemnified party which are different from or in
addition to those available to such indemnifying party or that representation of
such indemnifying party and any indemnified party by the same counsel would
present a conflict of interest, then one additional counsel in each jurisdiction
for all indemnified parties having consistent interests and such different or
additional defenses or subject to such conflict shall be entitled to conduct the
defense of such indemnified parties with the fees and expenses of such counsel
to be borne by the indemnifying party or parties. If an indemnifying party
assumes the defense of an action in accordance with and as permitted by the
provisions of this Section 4(c), such indemnifying party shall not be liable for
any fees and expenses of counsel for the indemnified parties incurred thereafter
in connection with such action (except to the extent set forth in the proviso
contained in the immediately preceding sentence). In no event shall the
indemnifying party or parties be liable for the fees and expenses of more than
one counsel for all indemnified parties in connection with any one action, or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances. No indemnifying party shall,
without the prior written consent of the indemnified parties, which consent
shall not be unreasonably withheld, settle or compromise or consent to the entry
of any judgment with respect to any litigation, or any investigation or
proceeding by any governmental agency or body, commenced or threatened, or any
claim whatsoever in respect of which indemnification or contribution could be
sought under this Section 4, unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and does not
include a statement as to or an admission of fault, culpability or a failure to
act by or on behalf of any indemnified party.

          (d) Notwithstanding any payment or payments made by the Company 
hereunder, the Company hereby expressly waives subrogation to, and agrees that
it shall not


                                       21

<PAGE>   22



be entitled to be subrogated to, any of the rights of any indemnified party
against the Company or any other right of offset held by any indemnified party
for the payment of any amounts owed to any indemnified party pursuant to this
Section 4; PROVIDED, HOWEVER, that if any of the foregoing provisions of this
paragraph are held to be contrary to applicable law or unenforceable by a court
of competent jurisdiction, the Company hereby expressly agrees that any right of
subrogation or contribution that the Company may have as a result of such
applicable law or unenforceability, as the case may be, shall be subordinate in
right of payment to the payment in full in cash of all amounts owed to any
indemnified party pursuant to this Section 4.

          (e) If the indemnification provided for in this Section 4 is for any 
reason unavailable to or insufficient to hold harmless an indemnified party in
respect of any losses, liabilities, claims, damages or expenses referred to
herein, then each indemnifying party shall contribute to the aggregate amount of
such losses, liabilities, claims, damages and expenses incurred by such
indemnified party, as incurred, (i) in such proportion as is appropriate to
reflect the relative benefits received by the indemnifying party or parties on
the one hand and the indemnified party or parties on the other hand from the
offering of the Notes pursuant to the Purchase Agreement, or (ii) if the
allocation provided by clause (i) 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 indemnifying party or
parties on the one hand and of the indemnified party or parties on the other
hand in connection with the statements or omissions which resulted in such
losses, liabilities, claims, damages or expenses, 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 hand in connection with the offering of the
Notes pursuant to the Purchase Agreement shall be deemed to be in the same
respective proportions as the total net proceeds from the offering of the Notes
pursuant to the Purchase Agreement (before deducting expenses) received by the
Company and the total discount received by the Initial Purchasers bear to the
aggregate initial offering price of the Notes.

          The relative fault of the Company on the one hand and the Holders on 
the other hand shall be determined by reference to, among other things, whether
any such untrue or alleged untrue statement of a material fact or omission or
alleged omission to sate a material fact relates to information supplied by the
Company or by the Holders, and the respective parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

          The Company and the Holders agree that it would not be just and 
equitable if contribution pursuant to this Section 4 were determined by pro rata
allocation (even if the Holders were treated as one entity for such purpose) or
by any other method of allocation which does not take account of the equitable
considerations referred to above in this Section 4(e). The aggregate amount of
losses, liabilities, claims, damages and expenses incurred by an indemnified
party and referred to above in this Section 4(e) shall be deemed to include



                                       22
<PAGE>   23



any legal or other expenses reasonably incurred by such indemnified party in
investigating, preparing for or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any untrue or alleged untrue
statement or omission or alleged omission referred to in Section 4(a)(i).

          Notwithstanding the provisions of this Section 4(e), no Initial 
Purchaser shall be required to contribute any amount in excess of the amount by
which the total discount received by such Initial Purchaser in respect of the
purchase price of the Notes purchased by it from the Company exceeds the amount
of any damages which the Initial Purchasers have 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 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          For purposes of this Section 4(c), each person, if any, who controls
an Initial Purchaser, a Holder, a Participating Broker-Dealer, an underwriter
who participates in an offering of Registrable Securities, or the affiliates of
any of them, within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act shall have the same rights to contribution as the Initial
Purchasers, and each director, officer (including each officer of the Company
who signed the Registration Statement), partner, employee, representative and
agent of the Company, the Initial Purchasers, each Holder, each Participating
Broker-Dealer, and each underwriter who participates in an offering of
Registrable Securities and each person, if any, who controls the Company within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall
have the same rights to contribution as the Company.

          5. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Holder 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
customary underwriting arrangements approved by the Holders of a majority in
aggregate principal amount of the Registrable Securities included in such
offering and (b) completes and executes all reasonable questionnaires, powers of
attorney, indemnities, underwriting agreements, lock-up letters and other
documents reasonably required in connection with such underwriting arrangements.

          6. SELECTION OF UNDERWRITERS. In any underwritten offering, the 
underwriter or underwriters and manager or managers that will administer the
offering will be selected by the Holders of a majority in aggregate principal
amount of the Registrable Securities included in such offering; PROVIDED,
HOWEVER, that such underwriters and managers must be reasonably satisfactory to
the Company.

                                                                       ---------


                           Form of Opinion of Counsel
                           --------------------------

          1. Each of the Exchange Offer Registration Statement and the 
Prospectus (other than the financial statements, notes or schedules thereto and
other financial and statistical data and supplemental schedules included or
referred to therein or omitted therefrom and the Form T-1 as to which such
counsel need express no opinion), complies as to form in all material respects
with the applicable requirements of the Act and the applicable rules and
regulations promulgated under the Act.

          2. In the course of such counsel's review and discussion of the 
contents of the Exchange Offer Registration Statement and the Prospectus with
certain officers and other representatives of the Company and representatives of
the independent certified public accountants of the Company, but without
independent check or verification or responsibility for the accuracy,
completeness or fairness of the statements contained therein, on the basis of
the foregoing (relying as to materiality to a large extent upon representations
and opinions of officers and other representatives of the Company), no facts
have come to such counsel's attention which cause such counsel to believe that
the Exchange Offer Registration Statement (other than the financial statements,
notes and schedules thereto and other financial and statistical information
contained or referred to therein and the Form T-l, as to which such counsel need
express no belief), at the time the Exchange Offer Registration Statement became
effective, contained an untrue statement of a material fact or omitted to state
a material fact required to be stated therein or necessary to make the
statements contained therein not misleading, or that the Prospectus (other than
the financial statements, notes and schedules thereto and other financial and
statistical information contained or referred to therein, as to which such
counsel need express no belief) contains any untrue statement of a material fact
or omits to state a material fact necessary to make the statements contained
therein, in the light of the circumstances under which they were made, not
misleading.

                            [Ropes & Gray Letterhead]



                                               April 18, 1997



Nortek, Inc.
50 Kennedy Plaza
Providence, Rhode Island 02903

Ladies and Gentlemen:

     This opinion is rendered to you in connection with a registration statement
(the "Registration Statement") on Form S-4 filed today with the Securities and
Exchange Commission under the Securities Act of 1933, as amended (the "Act"),
relating to the exchange offer (the "Exchange Offer") by Nortek, Inc. ("Nortek")
to exchange its $175,000,000 9 1/4% Series B Notes due 2007 (the "Exchange
Notes") for its outstanding $175,000,000 9 1/4% Series A Notes due 2007 (the
"Original Notes"). The Original Notes were, and the Exchange Notes are to be,
issued pursuant to the provisions of an indenture (the "Indenture") entered into
between Nortek and State Street Bank and Trust Company, a national banking
association, as Trustee (the "Trustee").

     We have acted as special counsel for Nortek in connection with the Exchange
Offer and the preparation of the Registration Statement. For purposes of this
opinion, we have examined and relied upon the information set forth in the
Registration Statement and such other documents and records as we have deemed
necessary. We express no opinion as to the laws of any jurisdiction other than
those of the Commonwealth of Massachusetts, the General Corporation Law of the
State of Delaware and the federal laws of the Unites States of America. We call
your attention to the fact that each of the Indenture and the Exchange Notes
provides that it is to be governed by the laws of the State of New York. For
purposes of the opinion provided herein, we have assumed with your permission
that the Indenture and the Exchange Notes would be governed by and construed in
accordance with the domestic substantive laws of The Commonwealth of
Massachusetts without giving effect to any choice of law or conflict of laws
rule or provision that would cause the application of the domestic substantive
laws of any other jurisdiction.

     Based upon the foregoing, we are of the opinion that, when the Exchange
Notes have been duly authorized, executed, issued and delivered as provided in
the Indenture, and delivered in exchange for the Original Notes, as described in
the Registration Statement, and assuming due authentication by the Trustee, the
Exchange Notes will constitute valid and binding obligations of Nortek,
enforceable against Nortek, in accordance with their terms, except as
enforceability (i) may be limited by bankruptcy, insolvency, reorganization or
other similar laws affecting creditors' rights generally (including, without
limitation, Section 548 of Title 11 of The United States Code and fraudulent
conveyance or similar provisions of state law) and (ii) is subject to general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law), and will be entitled to the benefits of the
Indenture.

     By execution hereof, the undersigned acknowledges receipt of the prospectus

Original Notes; or (iii) tender of Original Notes is to be made according to the

in whose name Original Notes are registered on the books of Nortek or any other
person who has obtained a properly completed bond power from the registered
Holder; or (ii) whose Original Notes are held of record by the Depository who

Ladies and Gentlemen:


     Subject to the terms of the Exchange Offer, the undersigned hereby tenders
to Nortek the principal amount of Original Notes indicated below. Subject to and
effective upon the acceptance for exchange of the principal amount of Original
Notes tendered in accordance with this Letter of Transmittal, the undersigned
sells, assigns and transfers to, or upon the order of, Nortek all right, title
and interest in and to the Original Notes tendered hereby. The undersigned
hereby irrevocably constitutes and appoints the Exchange Agent as its agent and
attorney-in-fact (with full knowledge that the Exchange Agent also acts as the
agent of Nortek and as Trustee under the Indenture for the Original Notes and
the Exchange Notes) with respect to the tendered Original Notes with full power
of substitution to (i) deliver certificates for such Original Notes to Nortek,
or transfer ownership of such Original Notes on the account books maintained by
The Depository Trust Company ("DTC") together, in either such case, with all
accompanying evidences of transfer and authenticity to, or upon the order of,
Nortek and (ii) present such Original Notes for transfer on the books of Nortek
and receive all benefits and otherwise exercise all rights of beneficial
ownership of such Original Notes, all in accordance with the terms of the
Exchange Offer. The power of attorney granted in this paragraph shall be deemed
irrevocable and coupled with an interest.

     The undersigned hereby represents and warrants that he or she has full
power and authority to tender, sell, assign and transfer the Original Notes
tendered hereby and that Nortek will acquire good and unencumbered title
thereto, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim, when the same are acquired by Nortek. The
undersigned also acknowledges that this Exchange Offer is being made in reliance
upon an interpretation by the staff of the Securities and Exchange Commission
that the Exchange Notes issued in exchange for the Original Notes pursuant to
the Exchange Offer may be offered for resale, resold and otherwise transferred
by any holder thereof (other than (i) a broker - dealer who purchased such
Original Notes directly from Nortek or any of its "affiliates" within the
meaning of Rule 405 under the Securities Act for resell pursuant to Rule 144A 
or any other available exemption under the Securities Act or (ii) a person that 
is such an "affiliate" of Nortek) without compliance with the registration and 
prospectus delivery provisions of the Securities Act provided that the holder 
is acquiring the Exchange Notes in its ordinary course of business and is not 
participating, and has no arrangement or understanding with any person to 
participate, in the distribution of the Exchange Notes.

     The undersigned represents that (i) the Exchange Notes acquired pursuant to
the Exchange Offer are being acquired by the undersigned and any beneficial
owner thereof in the ordinary course of business of the undersigned and any such
beneficial owner, (ii) neither the undersigned nor any such beneficial owner has
any arrangement or understanding with any person to participate in the
distribution of such Exchange Notes and (iii) except as indicated below, neither
the undersigned nor any such beneficial owner is an "affiliate," as defined
under Rule 405 of the Securities Act, of Nortek. If the undersigned or any
beneficial owner for whom the undersigned is tendering securities is an
affiliate of Nortek, then such person will comply with the registration and
prospectus delivery requirements of the Securities Act to the extent applicable.
If the undersigned or any beneficial owner for whom the undersigned is tendering
securities is a broker-dealer that will receive Exchange Notes for its own
account in exchange for Original Notes that were acquired as a result of
market-making or other trading activities, it acknowledges that it will deliver
a prospectus in connection with any resale of such Exchange Notes; however, by
so acknowledging and by delivering a prospectus, the undersigned or such
beneficial owner will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act.

     The undersigned will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or Nortek to be necessary or desirable to
complete the assignment and transfer of the Original Notes tendered hereby.

     For purposes of the Exchange Offer, Nortek shall be deemed to have accepted
validly tendered Original Notes when Nortek has given oral or written notice
thereof to the Exchange Agent. If any tendered Original Notes are not accepted
for exchange pursuant to the Exchange Offer for any reason, certificates for any
such unaccepted Original Notes will be returned (except as noted below with
respect to tenders through DTC), without expense, to the undersigned at the
address shown below or 


                                      -3-
<PAGE>   4
at a different address as may be indicated under "Special Issuance 
Instructions" as promptly as practicable after the Expiration Date.

     All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned and every obligation under this Letter of Transmittal shall be
binding upon the undersigned's heirs, personal representatives, successors and
assigns.

     The undersigned understands that tenders of Original Notes pursuant to the
procedures described under the caption "The Exchange Offer -- Procedures for
Tendering" in the Prospectus and in the instructions hereto will constitute a
binding agreement between the undersigned and Nortek upon the terms and subject
to the conditions of the Exchange Offer.

     Unless otherwise indicated under "Special Issuance Instructions," please
issue the certificates representing the Exchange Notes issued in exchange for
the Original Notes accepted for exchange and return any Original Notes not
tendered or not exchanged, in the name(s) of the undersigned (or in either such
event in the case of Original Notes tendered by DTC, by credit to the account at
DTC). Similarly, unless otherwise indicated under "Special Delivery
Instructions," please send the certificates representing the Exchange Notes
issued in exchange for the Original Notes accepted for exchange and any
certificates for Original Notes not tendered or not exchanged (and accompanying
documents, as appropriate) to the undersigned at the address shown below the
undersigned's signatures, unless, in either event, tender is being made through
DTC. In the event that both "Special Issuance Instructions" and "Special
Delivery Instructions" are completed, please issue the certificates representing
the Exchange Notes issued in exchange for the Original Notes accepted for
exchange and return any Original Notes not tendered or not exchanged in the
name(s) of, and send said certificates to, the person(s) so indicated. The
undersigned recognizes that Nortek has no obligation pursuant to the "Special
Issuance Instructions" and "Special Delivery Instructions" to transfer any
Original Notes from the name of the registered holder(s) thereof if Nortek does
not accept for exchange any of the Original Notes so tendered.

                                  INSTRUCTIONS

                    FORMING PART OF THE TERMS AND CONDITIONS
                   OF THE EXCHANGE OFFER AND THE SOLICITATION


     1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND ORIGINAL NOTES. The
certificates for the tendered Original Notes (or a confirmation of a book-entry
transfer into the Exchange Agent's account at DTC of all Original Notes
delivered electronically), as well as a properly completed and duly executed
copy of this Letter of Transmittal or facsimile hereof and any other documents
required by this Letter of Transmittal 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. The method of delivery of the tendered Original Notes, this
Letter of Transmittal and all other required documents to the Exchange Agent is
at the election and risk of the Holder and, except as otherwise provided below,
the delivery will be deemed made only when actually received by the Exchange
Agent. 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 Original Notes
should be sent to Nortek.

     Holders who wish to tender their Original Notes and (i) whose Original
Notes are not immediately available or (ii) who cannot deliver their Original
Notes, this Letter of Transmittal or any other documents required hereby to the
Exchange Agent prior to the Expiration Date must tender their Original Notes and
follow the guaranteed delivery procedures set forth in the Prospectus. Pursuant
to such procedures: (i) such tender must be made by or through an Eligible
Institution; (ii) prior to the Expiration Date, the Exchange Agent must have
received from the 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 of the Original Notes, the
certificate number or numbers of such Original Notes and the principal amount of
Original Notes tendered, stating that the tender is being made thereby and
guaranteeing that, within five business days after the Expiration Date, this
Letter of Transmittal (or facsimile hereof) together with the certificate(s)
representing the Original Notes (or a confirmation of electronic delivery of
book-entry delivery into the Exchange Agent's account at DTC) and any of the
required documents will be deposited by the Eligible Institution with the
Exchange Agent; and (iii) such properly completed and executed Letter of
Transmittal (or facsimile hereof), as well as all other documents required by
this Letter of Transmittal and the certificate(s) representing all tendered
Original Notes in proper form for transfer (or a confirmation of electronic mail
delivery of book-entry delivery into the Exchange Agent's account at DTC), must
be received by the Exchange Agent within five business days after the Expiration
Date, all as provided in the Prospectus under the caption "Exchange Offers --
Guaranteed Delivery Procedures." Any Holder of Original Notes who wishes to
tender his Original Notes pursuant to the guaranteed delivery procedures
described above must ensure that the Exchange Agent receives the Notice of
Guaranteed Delivery prior to 5:00 P.M., New York City time, on the Expiration
Date.

     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Original Notes will be
determined by Nortek in its sole discretion, which determination will be final
and binding. Nortek reserves the absolute right to reject any and all Original
Notes not properly tendered or any Original Notes Nortek's acceptance of which
would, in the opinion of counsel for Nortek, be unlawful. Nortek also reserves
the right to waive any irregularities or conditions of tender as to particular
Original Notes. Nortek's interpretation of the terms and conditions of the
Exchange Offer (including the instructions in this Letter of Transmittal) will
be final and binding on all parties. Unless waived, any defects or
irregularities in connection with tenders of Original Notes must be cured within
such time as Nortek shall determine. Neither Nortek, the Exchange Agent nor any
other person shall be under any duty to give notification of defects or
irregularities with respect to tenders of Original Notes, nor shall any of them
incur any liability for failure to give such notification. Tenders of Original
Notes will not be deemed to have been made until such defects or irregularities
have been cured or waived. Any Original 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 without cost by the Exchange
Agent to the tendering Holders of Original Notes, unless otherwise provided in
this Letter of Transmittal, as soon as practicable following the Expiration
Date.

     2. PARTIAL TENDERS. Tenders of Original Notes will be accepted in all
denominations of $1,000 principal amount and integral multiples in excess
thereof. If less than the entire principal amount of any Original Note is
tendered, the tendering Holder should fill in the principal amount tendered in
the third column 

                                      -11-
<PAGE>   12

of the chart entitled "Description of Original Notes Tendered." The entire
principal amount of Original Notes delivered to the Exchange Agent will be
deemed to have been tendered unless otherwise indicated. If the entire principal
amount of all Original Notes is not tendered, Original Notes for the principal
amount of Original Notes not tendered and a certificate or certificates
representing Exchange Notes issued in exchange for any Original Notes 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 or
unless tender is made through DTC, promptly after the Original Notes are
accepted for exchange.

     3. SIGNATURES ON THE LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS;
GUARANTEE OF SIGNATURES. If this Letter of Transmittal (or facsimile hereof) is
signed by the registered Holder(s) of the Original Notes tendered hereby, the
signature must correspond with the name(s) as written on the face of the
Original Notes without alteration, enlargement or any change whatsoever.

     If this Letter of Transmittal (or facsimile hereof) is signed by the
registered Holder(s) of Original Notes tendered and the certificate(s) for
Exchange Notes issued in exchange therefor is to be issued (or any untendered
principal amount of Original Notes is to be reissued) to the registered Holder,
such Holder need not and should not endorse any tendered Original Note, nor
provide a separate bond power. In any other case, such Holder must either
properly endorse the Original Notes tendered or transmit a properly completed
separate bond power with this Letter of Transmittal, with the signatures on the
endorsement or bond power guaranteed by an Eligible Institution.

     If this Letter of Transmittal (or facsimile hereof) is signed by a person
other than the registered Holder(s) of any Original Notes listed, such Original
Notes must be endorsed or accompanied by appropriate bond powers signed as the
name of the registered Holder(s) appears on the Original Notes.

     If this Letter of Transmittal (or facsimile hereof) or any Original Notes
or bond powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, or officers of corporations or other acting in a fiduciary or
representative capacity, such persons should so indicate when signing, and
unless waived by Nortek, evidence satisfactory to of their authority so to act
must be submitted with this Letter of Transmittal.

     Endorsements on Original Notes or signatures on bond powers required by
this Instruction 3 must be guaranteed by an Eligible Institution.

     Signatures on this Letter of Transmittal (or facsimile hereof) must be
guaranteed by an Eligible Institution unless the Original Notes tendered
pursuant thereto are tendered (i) by a registered Holder (including any
participant in DTC whose name appears on a security position listing as the
owner of Original Notes) who has not completed the box set forth herein entitled
"Special Issuance Instructions" or the box entitled "Special Delivery
Instructions" or (ii) for the account of an Eligible Institution.

     4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. Tendering Holders should
indicate, in the applicable spaces, the name and address to which Exchange Notes
or substitute Original Notes for principal amounts not tendered or not accepted
for exchange are to be issued or sent, if different from the name and address of
the person signing this Letter of Transmittal (or in the case of tender of the
Original Notes through DTC, if different from DTC). In the case of issuance in a
different name, the taxpayer identification or social security number of the
person named must also be indicated.

     5. TRANSFER TAXES. Nortek will pay all transfer taxes, if any, applicable
to the exchange of Original Notes pursuant to the Exchange Offer. If, however,
certificates representing Exchange Notes or Original Notes for principal amounts
not tendered or accepted for exchange are to be delivered to, or are to be
registered or issued in the name of, any person other than the registered Holder
of the Original Notes tendered hereby, or if tendered Original Notes are
registered in the name of any person other than the person signing this Letter
of Transmittal, or if a transfer tax is imposed for any reason other than the
exchange of Original Notes pursuant to the Exchange Offer, then the amount of
any such transfer taxes (whether imposed on the registered Holder or 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 5, it will not be necessary for
transfer tax stamps to be affixed to the Original Notes listed in this Letter of
Transmittal.

     6. WAIVER OF CONDITIONS. Nortek reserves the absolute right to amend, waive
or modify specified conditions in the Exchange Offer in the case of any Original
Notes tendered.

     7. MUTILATED, LOST, STOLEN OR DESTROYED ORIGINAL SENIOR SUBORDINATED NOTES.
Any tendering Holder whose Original Notes have been mutilated, lost, stolen or
destroyed should contact the Exchange Agent at the address indicated herein for
further instruction.

     8. 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 specified in
the Prospectus and herein. Holders may also contact their broker, dealer,
commercial bank, trust company or other nominee for assistance concerning the

                            IMPORTANT TAX INFORMATION

Under federal income tax laws, a Holder whose tendered Original Notes are
accepted for payment is required to provide the Exchange Agent (as payer) with
such Holder's correct TIN on Substitute Form W-9 below or otherwise establish a
basis for exemption from backup withholding. If such Holder is an individual,
the TIN is his social security number. If the Exchange Agent is not provided
with the correct TIN, a $50 penalty may be imposed by the Internal Revenue
Service, and payments made with respect to Original Notes purchased pursuant to
the Exchange Offer may be subject to backup withholding.

Certain Holders (including, among others, all corporations and certain foreign
persons) are not subject to these backup withholding and reporting requirements.
Exempt Holders should indicate their exempt status on Substitute Form W-9. A
foreign person may qualify as an exempt recipient by submitting to the Exchange
Agent a properly completed Internal Revenue Service Form W-8, signed under
penalties of perjury, attesting to that Holder's exempt status. A Form W-8 can
be obtained from the Exchange Agent. See the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional instructions.

If backup withholding applies, the Exchange Agent is required to withhold 31% of
any payments made to the Holder or other payee. Backup withholding is not an
additional federal income tax. Rather, the federal income tax liability of
persons subject to backup withholding will be reduced by the amount of tax
withheld. If withholding results in an overpayment of taxes, a refund may be
obtained from the Internal Revenue Service.

PURPOSE OF SUBSTITUTE FORM W-9

To prevent backup withholding on payments made with respect to the Exchange
Offer, the Holder is required to provide the Exchange Agent with either: (i) the
Holder's correct TIN by completing the form above, certifying that the TIN
provided on Substitute Form W-9 is correct (or that such Holder is awaiting a
TIN) and that (A) the Holder has not been notified by the Internal Revenue
Service that the Holder is subject to backup withholding as a result of failure
to report all interest or dividends or (B) the Internal Revenue Service has
notified the Holder that the Holder is no longer subject to backup withholding;
