                  12 1/2% SENIOR DISCOUNT DEBENTURES DUE 2008
                                IN EXCHANGE FOR
                  12 1/2% SENIOR DISCOUNT DEBENTURES DUE 2008
                                       OF
 
                        THERMADYNE HOLDINGS CORPORATION
 
Thermadyne Holdings Corporation ("Holdings" or the "Company") hereby offers,
upon the terms and subject to the conditions set forth in this Prospectus and
the accompanying Letter of Transmittal (which together constitute the "Exchange
Offer"), to exchange $1,000 principal amount at maturity of registered 12 1/2%
Senior Discount Debentures due 2008 (the "New Debentures") issued by the Company
for each $1,000 principal amount at maturity of unregistered 12 1/2% Senior
Discount Debentures due 2008 (the "Old Debentures") issued by the Company, of
which an aggregate principal amount at maturity of $174,000,000 is outstanding.
The form and terms of the New Debentures are identical to the form and terms of
the Old Debentures except that the New Debentures have been registered under the
Securities Act of 1933, as amended (the "Securities Act"), and will not bear any
legends restricting their transfer. The New Debentures will evidence the same
debt as the Old Debentures and will be issued pursuant to, and entitled to the
benefits of, the Indenture (as defined) governing the Old Debentures. The
Exchange Offer is being made in order to satisfy certain contractual obligations
of the Company. See "The Exchange Offer" and "Description of New Debentures."
The New Debentures and the Old Debentures are sometimes collectively referred to
herein as the "Debentures."
 
The New Debentures will mature on June 1, 2008. The New Debentures will accrete
at a rate of 12 1/2%, compounded semiannually, to an aggregate principal amount
at maturity of $174 million on June 1, 2003. Cash interest will not accrue on
the New Debentures prior to June 1, 2003. Commencing on June 1, 2003, cash
interest on the New Debentures will be payable, at a rate of 12 1/2% per annum,
semi-annually in arrears on each June 1 and December 1, commencing December 1,
2003. See "Description of New Debentures."
 
The New Debentures will be subject to redemption at any time on or after June 1,
2003 at the option of the Company, in whole or in part, in cash at the
redemption prices set forth herein, plus accrued and unpaid interest and
Liquidated Damages (as defined herein), if any, thereon to the applicable
redemption date. Notwithstanding the foregoing, on or prior to June 1, 2001, the
Company may redeem up to 100% of the aggregate principal amount at maturity of
Debentures ever issued under the Indenture in cash at a redemption price of
112.50% of the Accreted Value (as defined herein) thereof, plus Liquidated
Damages, if any, thereon to the redemption date, with the net cash proceeds of
one or more Public Equity Offerings (as defined herein); provided that, in the
event that the Company redeems less than 100% of the then outstanding
Debentures, at least 60% of the aggregate principal amount at maturity of
Debentures ever issued under the Indenture remains outstanding immediately after
the occurrence of any such redemption. In addition, at any time prior to June 1,
2003, the Issuer may, at its option upon the occurrence of a Change of Control
(as defined herein), redeem the New Debentures, in whole but not in part, in
cash at a redemption price equal to (i) the present value of the sum of all the
remaining premium and principal payments that would become due on the New
Debentures as if the New Debentures were to remain outstanding and be redeemed
on June 1, 2003, computed using a discount rate equal to the Treasury Rate (as
defined herein) plus 50 basis points, plus (ii) Liquidated Damages, if any, to
the date of redemption. Upon the occurrence of a Change of Control, each Holder
of New Debentures will have the right to require the Company to repurchase all
or any part of such Holder's New Debentures at an offer price in cash equal to
101% of the Accreted Value thereof, plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the date of repurchase. See "Description
of New Debentures."
 
The New Debentures will be senior obligations of the Company. The New Debentures
will rank pari passu in right of payment with all future senior indebtedness of
the Company and will rank senior in right of payment to all future indebtedness
of the Company that is subordinated to the New Debentures. The New Debentures
will be effectively subordinated to all liabilities of the Company's
subsidiaries. On a pro forma basis after giving effect to the Merger (as defined
herein), including the Merger Financing (as defined herein) and the application
of the proceeds therefrom, as of March 31, 1998, the Company (as defined herein)
would have had outstanding approximately $682.0 million of Indebtedness (as
defined herein) and the Company's subsidiaries would have had approximately
$733.2 million of liabilities outstanding, including Indebtedness under the
Senior Subordinated Notes (as defined herein) and the New Credit Facility (as
defined herein) and including trade payables.

The Company will accept for exchange any and all Old Debentures validly tendered
and not withdrawn prior to 5:00 p.m., New York City time, on           , 1998,
unless extended (as so extended, the "Expiration Date"). Tenders of Old
Debentures may be withdrawn at any time prior to the Expiration Date. The
Exchange Offer is subject to certain customary conditions. See "The Exchange

Each broker-dealer that receives New Debentures for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Debentures. The letter of transmittal

activities. The Company has agreed, for a period of 90 days after the Expiration
Date, to make this Prospectus available to any broker-dealer for use in
connection with any such resale. See "Plan of Distribution."

Company currently does not intend to list the New Debentures on any securities
exchange or to seek approval for quotation through any automated quotation
system, and no active public market for the New Debentures is currently

Offer.

                                  THE COMPANY
 
OVERVIEW
 
     Thermadyne is a leading global manufacturer of cutting and welding products
and accessories. The Company manufactures a broad range of gas (oxy-fuel) and
electric arc cutting and welding products that are ultimately sold to end-user
customers principally engaged in the aerospace, automotive, construction, metal
fabrication, mining, mill and foundry, petroleum and shipbuilding industries.
Thermadyne sells its products through a long-established domestic network of
approximately 1,100 independent distributors who market Thermadyne products to
over 10,000 end-user customers. For the twelve months ended March 31, 1998, the
Company's net sales and Adjusted EBITDA (as defined herein), on a pro forma
basis, were $548.2 million and $115.5 million, respectively.
 
     The Company's core products enjoy leading brand recognition, a reputation
for quality and strong market positions. In 1994, following the Company's
Restructuring (as defined herein), current management initiated a series of
transactions to focus the Company's business exclusively on the cutting and
welding industry. As part of this strategy, the Company divested three non-core
businesses and acquired six cutting and welding businesses, which collectively
generated approximately $169 million in annual revenues at the respective times
of acquisition. As a result of this repositioning strategy, along with ongoing
new product introductions, an extensive distribution network and market leading
brands, the Company has achieved a compound annual growth in net sales and
EBITDA of 20.3% and 12.5%, respectively, from 1993 to 1997.
 
     According to the United States Department of Commerce, domestic welding
industry revenues totaled over $3.6 billion in 1997. The domestic industry has
grown at an annual rate of 5.9% since 1989 and is expected to grow 4.2% in 1998.
Global welding industry revenues are estimated to total over $10.0 billion, and
management believes that growth in the international market has been faster than
the domestic market, driven, in large part, by infrastructure spending in
developing markets. International markets, including Australia and Italy,
represented approximately 42% of the Company's net sales in 1997, up from
approximately 20% of net sales in 1994. Although the industry has begun to
experience global consolidation, it continues to be very fragmented.
 
COMPETITIVE STRENGTHS
 
     Thermadyne possesses a number of competitive strengths that have allowed it
to develop and maintain a strong position within the cutting and welding
industry, including the following:
 
     Market Leading Brands. Management believes that the strength and longevity
of the numerous Thermadyne brand names create a significant competitive
advantage and position Thermadyne as one of the leaders in the cutting and
welding industry. Each of the Company's major divisions maintains
industry-leading brand names with significant market shares. Management believes
that VICTOR(R), founded in 1913, is the leading brand name in domestic
gas-operated cutting and welding torches and equipment; TWECO(R), founded in
1936, is the leading domestic manufacturer of metal inert gas ("MIG") and manual
welding torches; ARCAIR(R) is the leading domestic brand name of tungsten inert
gas ("TIG") torch and accessory products; THERMAL
 
                                        3
<PAGE>   5
 
DYNAMICS(R), founded in 1957, is a leading domestic manufacturer of manual
plasma cutting products; and CIGWELD(R), founded in 1922, is the leading brand
name in the Australia/New Zealand cutting and welding products market. Each of
the manufacturing operations associated with these brands is ISO-9000 series
certified.
 
     Diverse and Stable Customer Base. The Company's customer base includes
cutting and welding product distributors as well as end-user customers
principally engaged in the aerospace, automotive, construction, metal
fabrication, mining, mill and foundry, petroleum and ship building industries.
No one customer accounted for more than 9% of the Company's 1997 net sales.
Further, the Company's top 20 customers have been associated with the Company
for an average of over 10 years.
 
     Established, Effective Distribution Channels. The Company believes that its
strong, established and long-standing relationships with over 1,100 independent
cutting and welding products distributors in the United States provide a
significant competitive advantage and support the Company's strong market
position. Thermadyne's domestic distributor relationships are maintained by 11
area business managers who oversee the Company's relationships with large
distributors and by separate product-specific sales forces for each of
Thermadyne's business units. Management believes that this unique structure,
which combines relationship managers with technically trained product
specialists, will enable the Company to more effectively maintain and utilize
its distributor networks. Management also believes that this established
distribution network enables the Company to achieve market penetration when
introducing newly developed or acquired products.
 
     Proven and Committed Senior Management Team. Thermadyne's management team
has strategically repositioned the Company over the past four years to focus
exclusively in its core cutting and welding markets. This repositioning was
accomplished through divestitures of three non-core assets and acquisitions of
six strategic businesses or product lines. In addition, management has initiated
the development and introduction of significant new products and product lines.
As a result of management's efforts, the Company achieved a 20.3% growth rate in
net sales from 1993 to 1997. In connection with the Merger each member of the
senior management team signed an employment contract with the Company.
Additionally, the Company adopted an incentive plan to tie each member of senior
management's compensation to the Company's financial performance. See "Executive
Compensation."
 
BUSINESS STRATEGY
 
     Thermadyne has developed a business strategy designed to enhance its strong
market positions and continue to improve its growth and profitability. The
primary elements of the Company's business strategy are as follows:
 
     Continue New Product Development and Enhancement. The foundation for
Thermadyne's strong market positions and leading brand names is the development
and introduction of new products and enhancements of existing products. The
Company believes it is at the forefront of cutting and welding technology with a
proven track-record of continual new product introductions and existing product
enhancements that have resulted in 262 issued or pending United States and
foreign patents. New products and product enhancements are designed to add value
for customers, including enhanced safety features, improved productivity and
ergonomics and an improved welding environment. Examples of recent new product
introductions include robotic welding systems and accessories, high-purity
instrumentation, automated plasma cutting and safety products as well as
underwater cutting electrodes. During 1997, the Company introduced over 135 new
products or product enhancements, and the Company expects to continue this
effort in the future.
 
     Expand Strategic Acquisitions. The Company has completed six acquisitions
since 1994, which collectively generated approximately $169 million in annual
revenues at the respective times of acquisition, including over $135 million of
revenues in Australia and Italy. The Company believes that numerous acquisition
candidates exist globally, and the Company intends to continue to seek new
acquisition opportunities in its cutting and welding business. Thermadyne
intends to continue its focused acquisition strategy that includes the following
principal elements: (i) entering and expanding in geographic areas where the
Company does not currently have a significant presence through acquisitions of
local cutting and welding
 
                                        4
<PAGE>   6
 
businesses and (ii) expanding in geographic areas where the Company currently
maintains a strong presence through the acquisition of complementary product
lines.
 
     Leverage Existing Distribution Network. The Company intends to leverage its
existing distribution network through the acquisition or introduction of new
products and product enhancements. Management believes that when the Company
acquires a local presence in a new geographic area, it can utilize the acquired
distribution network to sell existing Thermadyne brands into that local market.
In addition, the Company believes that significant opportunities exist to
purchase complementary product lines and expand its business by selling the new
product lines through Thermadyne's extensive distribution network. For example,
through recent acquisitions the Company has expanded its offering of filler
metals, conventional arc welding power supplies, safety equipment and
engine-driven welding power sources and began marketing such products through
its established distribution network. The Company intends to continue this
strategy of penetrating new welding product markets by leveraging its extensive
distribution network in conjunction with its new product development and focused
acquisition strategies.
 
     Broaden International Presence. Thermadyne has maintained an international
presence for over 30 years and continues to broaden its presence throughout the
world. International sales accounted for approximately 42% of net sales in 1997
as compared to approximately 20% in 1994. The Company has established a
dedicated international market presence and maintains the leading position in
Australia/New Zealand and significant and growing positions in Europe, Asia and
Latin America. Management intends to continue the expansion of its strong
domestic brand names into the international market and to continue to penetrate
the growing Asian and Latin American cutting and welding markets.
 
     Continue Cost Reduction Efforts. Thermadyne strives to continually improve
manufacturing efficiencies and reduce unit costs. In December 1997, the Company
implemented a cost reduction program that includes the following principal
elements: (i) vendor rationalization and consolidation; (ii) manufacturing
process and product improvements and product design changes; (iii) personnel
rationalization and expense reductions; (iv) advertising and trade show expense
reductions; (v) aircraft, charter and other travel expense reductions; and (vi)
elimination of the annual sales meeting. These cost reduction initiatives are
expected to generate approximately $10 million in savings on an annualized
basis. In addition, the Company has initiated the implementation of a new global
information system that is designed to allow the Company to further integrate
administrative functions and improve information flow across business unit
lines.
 
     Continue Dedicated Customer Service. The Company believes that effective
and proactive customer service has enabled the Company to build and maintain its
leading market positions and strong distributor relationships. Management plans

                        THE MERGER AND MERGER FINANCING
 
     On May 22, 1998, Holdings consummated the merger of Mercury Acquisition
Corporation ("Mercury"), a corporation organized by DLJ Merchant Banking
Partners II, L.P. ("DLJMB") and affiliated funds and entities (the "DLJMB
Funds"), with and into Holdings, with Holdings continuing as the surviving
corporation (the "Merger").
 
     In order to fund the payment of the cash portion of the Merger
Consideration (as defined herein), the Option Cash Proceeds (as defined herein)
and the ESPP Cash Proceeds (as defined herein), to refinance and/or retire
outstanding indebtedness of the Company, and to pay expenses incurred in
connection with the Merger, Thermadyne LLC and Thermadyne Capital issued $207
million principal amount of 9 7/8 Senior Subordinated Notes due 2008 (the
"Senior Subordinated Notes") and Thermadyne LLC entered into a syndicated senior
secured loan facility providing for term loan borrowings in the aggregate
principal amount of approximately $330 million and revolving loan borrowings of
$100 million (the "New Credit Facility").In connection with the Merger,
Thermadyne LLC borrowed all term loans available under the New Credit Facility
plus approximately $25 million of revolving loans. The remaining revolving loans
will be available to fund the working capital requirements of Thermadyne LLC.
The proceeds of such financings were distributed to Holdings in the form of a
dividend. See "Description of New Credit Facility," "The Merger and Merger
Financing" and "Certain Relationships and Related Transactions."
 
     Mercury issued approximately $94.6 million aggregate proceeds of the
Debentures. In connection with the Merger, Holdings succeeded to the obligations
of Mercury with respect to the Debentures. The DLJMB Funds also purchased
2,608,696 shares of common stock of Mercury ("Mercury Common Stock"), 2,000,000
shares of Mercury Preferred Stock ("Mercury Preferred Stock") and warrants to
purchase 353,428 shares of Mercury Common Stock at an exercise price of $0.01
per share (the "DLJMB Warrants") for approximately $140 million (the "DLJMB
Equity Investment"). As a result of the Merger, the proceeds of such purchases
became an asset of Holdings, each share of Mercury Common Stock became a share
of Holdings ("Holdings Common Stock"), each share of Mercury Preferred Stock
became a share of senior exchangeable preferred stock of Holdings ("Holdings
Preferred Stock") and each DLJMB Warrant to acquire Mercury Common Stock became
exercisable for an equal number of shares of Holdings Common Stock. In addition,
in connection with the Merger, certain members of senior management purchased
143,192 shares of Holdings Common Stock for approximately $4.9 million (the
"Management Share Purchase"), of which approximately $3.6 million was provided
through non-recourse loans from Holdings (the "Management Loans").
 
     The equity and debt financings referred to above are collectively referred
to herein as the "Merger Financing."

                               THE EXCHANGE OFFER
 
The Exchange Offer.........  $1,000 principal amount at maturity of New
                             Debentures in exchange for each $1,000 principal
                             amount at maturity of Old Debentures. The Old
                             Debentures were sold on May 22, 1998 in a private
                             placement to Donaldson, Lufkin & Jenrette
                             Securities Corporation (the "Initial Purchaser"),
                             which immediately resold the Old Debentures
                             pursuant to Rule 144A promulgated under the
                             Securities Act (the "Offering"). As of the date
                             hereof, Old Debentures representing $174 million
                             aggregate principal amount at maturity are
                             outstanding. The terms of the New Debentures and
                             the Old Debentures are substantially identical in
                             all material respects, except that the New
                             Debentures will be freely transferable by the
                             holders thereof except as otherwise provided
                             herein. See "Description of New Debentures."
 
                             Based on an interpretation by the Commission's
                             staff set forth in no-action letters issued to
                             third parties unrelated to the Issuer, the Issuer
                             believes that New Debentures issued pursuant to the
                             Exchange Offer in exchange for Old Debentures may
                             be offered for resale, sold and otherwise
                             transferred by any person receiving the New
                             Debentures, whether or not that person is the
                             registered holder (other than any such holder or
                             such other person that is an "affiliate" of the
                             Issuer within the meaning of Rule 405 under the
                             Securities Act), without compliance with the
                             registration and prospectus delivery provisions of
                             the Securities Act, provided that (i) the New
                             Debentures are acquired in the ordinary course of
                             business of that holder or such other person, (ii)
                             neither the holder nor such other person is
                             engaging in or intends to engage in a distribution
                             of the New Debentures and (iii) neither the holder
                             nor such other person has an arrangement or
                             understanding with any person to participate in the
                             distribution of the New Debentures. See "The
                             Exchange Offer -- Purpose and Effect." Each

                             those Old Debentures were acquired by the
                             broker-dealer as a result of its market-making
                             activities or other trading activities, must
                             acknowledge that it will deliver a prospectus in
                             connection with any resale of these New Debentures.

                             at least 60% of the aggregate principal amount at
                             maturity of Debentures ever issued under the
                             Indenture remains outstanding immediately after the
                             occurrence of any such redemption. In addition, at
                             any time prior to June 1, 2003, the Issuer may, at
                             its option upon the occurrence of a Change of
                             Control, redeem the Debentures, in whole but not in
                             part, in cash at a redemption price equal to (i)
                             the present value of the sum of all the remaining
                             premium and principal payments that would become
                             due on the Debentures as if the Debentures were to
                             remain outstanding and be redeemed on June 1, 2003,
                             computed using a discount rate equal to the
                             Treasury Rate plus 50 basis points, plus (ii)
                             Liquidated Damages, if any, to the date of
                             redemption. See "Description of New
                             Debentures -- Optional Redemption."
 
Change of Control..........  Upon the occurrence of a Change of Control, each
                             Holder of the New Debentures will have the right to
                             require the Issuer to repurchase all or any part of
                             such Holder's New Debentures at an offer price in
                             cash equal to 101% of the Accreted Value thereof,
                             in the case of any such purchase prior to June 1,
                             2003, or 101% of the aggregate principal amount at
                             maturity thereof, in the case of any such purchase
                             on or after June 1, 2003, in each case, plus
                             accrued and unpaid interest and Liquidated Damages,
                             if any, thereon to the date of repurchase. No
                             assurance can be given that the Issuer will have
                             sufficient resources to satisfy its repurchase
                             obligations with respect to the New Debentures
                             following a Change of Control. See "Risk
                             Factors -- Possible Inability to Repurchase New
                             Debentures upon Change of Control" and "Description
                             of New Debentures -- Repurchase at the Option of

Ranking....................  The New Debentures will be senior obligations of
                             the Issuer. The New Debentures will rank pari passu
                             in right of payment with all future senior
                             indebtedness of the Issuer and will rank senior in
                             right of payment to all future indebtedness of the
                             Issuer that is subordinated to the New Debentures.
                             The New Debentures will be effectively subordinated
                             to all liabilities of the Issuer's subsidiaries. On
                             a pro forma basis, after giving effect to the
                             Merger, including the Merger Financing and the
                             application of the proceeds therefrom, as of March
                             31, 1998, the Issuer would have had outstanding
                             approximately $682.0 million of Indebtedness and
                             the Issuer's subsidiaries would have had
                             approximately $733.2 million of liabilities
                             outstanding, including Indebtedness under the
                             Senior Subordinated Notes and the New Credit
                             Facility and including trade payables.
 
Original Issue Discount....  The Old Debentures were issued at an original issue
                             discount for United States federal income tax
                             purposes. Thus, although cash interest will not
                             accrue on the Debentures prior to June 1, 2003,
                             original issue discount (i.e., the difference
                             between the sum of all principal and interest
                             payable on the Debentures and the issue price of
                             the Debentures) will accrue from the issue date of
                             the Debentures and will be included as interest
                             income periodically (including for periods ending
                             prior to June 1, 2003) in a holder's gross income
                             for United States federal income tax purposes in
                             advance of receipt of the cash payments to which
                             the income is attributable. See "Certain United
                             States Federal Income Tax Considerations."
 
Certain Covenants..........  The indenture pursuant to which the New Debentures
                             will be issued (the "Indenture") contains certain
                             covenants that, among other things, limit the
                             ability of the Issuer and its Restricted
                             Subsidiaries to: incur indebtedness and issue
                             preferred stock, repurchase Capital Stock (as
                             defined herein) and certain Indebtedness, engage in
                             transactions with affiliates, engage in sale and
                             leaseback transactions, incur or suffer to exist
                             certain liens, pay dividends or other
                             distributions, make certain investments, sell
                             assets and engage in certain mergers and
                             consolidations.
 
Use of Proceeds............  There will be no cash proceeds to the Issuer from
                             the exchange pursuant to the Exchange Offer. The
                             net proceeds from the Offering, together with the
                             initial borrowings under the New Credit Facility,
                             the DLJMB Equity Investment and the issuance of the
                             Senior Subordinated Notes, were used to fund
                             payment of the cash portion of the Merger
                             Consideration, the Option Cash Proceeds and the
                             ESPP Cash Proceeds, to refinance outstanding
                             indebtedness of Thermadyne LLC and to pay the
                             expenses incurred in connection with the Merger.
                             See "Use of Proceeds."

     See "Risk Factors" for a discussion of certain factors that should be
considered in connection with an investment in the New Debentures.

              SUMMARY HISTORICAL AND UNAUDITED PRO FORMA CONDENSED
                       CONSOLIDATED FINANCIAL INFORMATION
 
     The summary historical consolidated financial data for and as of the end of
each of the years in the five-year period ended December 31, 1997 set forth
below have been derived from the audited consolidated financial statements of
the Company's predecessor, Holdings. The pro forma financial data for the three-
month period ended March 31, 1998 and the historical financial data for the
three-month period ended March 31, 1997, respectively, are derived from
unaudited financial statements. The unaudited financial statements include all
adjustments, consisting only of normal recurring adjustments, which the Company
considers necessary for a fair presentation of the financial position and the
results of operations for these periods. Operating results for the pro forma
three-month period ended March 31, 1998 are not necessarily indicative of the
results that may be expected for the entire year ending December 31, 1998. The
data should be read in conjunction with the historical consolidated financial
statements of the Company and its predecessor, and the related notes thereto,
set forth elsewhere herein.
 
     The unaudited summary consolidated pro forma financial data of the Company
set forth below are based on historical consolidated financial statements of
Holdings as adjusted to give effect to certain transactions described below and
the Merger, including the Merger Financing and the application of the proceeds
thereof. The pro forma balance sheet data give effect to the Merger, including
the Merger Financing and the application of the proceeds thereof, as if it had
occurred on March 31, 1998. The pro forma statement of operations data for the
three-month period ended March 31, 1998 gives effect to the Merger and the
Merger Financing and the application of the proceeds thereof as if it had
occurred at the beginning of such period. The pro forma statement of operations
data for the twelve months ended March 31, 1998 give effect to the acquisition
of the welding division of Prestolite Power Corporation ("Arcsys"), which
occurred on September 26, 1997 (the "Arcsys Acquisition"), the acquisition of
certain assets of Woodland Cryogenics, Inc. ("Woodland"), which occurred on
November 25, 1997 (the "Woodland Acquisition"), and the Merger, including the
Merger Financing and the application of the proceeds thereof, as if they all had
occurred on April 1, 1997. The pro forma statement of operations data for the
twelve months ended March 31, 1998 and the three-month period ended March 31,
1998 have been derived as if the balance sheet of the Company at the beginning
of such period was the pro forma balance sheet as of March 31, 1998. The pro
forma adjustments are based upon available information and upon certain
assumptions that management believes are reasonable under the circumstances. The
pro forma financial data do not purport to represent what the Company's actual
results of operations or actual financial position would have been if the Arcsys
Acquisition, the Woodland Acquisition and the Merger, including the Merger
Financing and the application of the proceeds thereof, had occurred on such
dates or to project the Company's results of operations or financial position
for any future period or date.
 
     In 1996, Holdings announced plans to sell, and in 1997 consummated the sale
of, its wear resistance business; in late 1995, Holdings announced its plans to
sell, and in 1996 consummated the sale of, its gas containment and floor
maintenance businesses. These businesses are accounted for as discontinued
operations in Holdings' Consolidated Financial Statements. The following data
should be read in conjunction with "Unaudited Condensed Consolidated Pro Forma
Financial Data," "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and Holdings' Consolidated Financial Statements and
Notes thereto, in each case included elsewhere herein.

 (1) Represents the eleven-month period from February 1, 1994, the effective
     date of the Company's comprehensive financial restructuring under chapter
     11 of the United States Bankruptcy Code (the "Restructuring"), through
     December 31, 1994.
 
 (2) See "Business -- Business Strategy" and the discussion under the caption
     "Recent Events -- Acquisitions" in Note 2 to Holdings' Consolidated
     Financial Statements for information concerning the Company's business
     combinations occurring during the periods presented.
 
 (3) In conjunction with the Restructuring, Holdings' assets and liabilities
     were revalued at the effective date thereof. The assets and liabilities
     were stated at their reorganization value. The portion of the
     reorganization value not attributable to specific assets was amortized over
     a three year period.
 
 (4) Includes $33.0 million in 1995 related to the writedown of intangible
     assets in accordance with Financial Accounting Standards Board Statement
     No. 121.

 (5) During 1993, nonrecurring charges of $18.9 million were recorded resulting
     from writing off unamortized debt discount and deferred financing costs and
     other costs related to the Restructuring.
 
 (6) Excludes net assets of discontinued operations for 1995 and 1996.
 
 (7) For 1993, includes liabilities subject to compromise of $466.2 million.
 
 (8) Holdings will issue two million shares of a new series of preferred stock
     in exchange for an identical number of shares of preferred stock of Merger
     Sub. This new preferred stock, referred to elsewhere herein as Mirror
     Preferred Stock, will have a liquidation preference of $25 per share, or
     $50 million in the aggregate, and a quarterly dividend, payable for the
     first 5 years through increases in the liquidation preference of the Mirror
     Preferred Stock, at an annual rate of approximately 13%, or $6.5 million in
     the aggregate.
 
 (9) "Adjusted EBITDA" is defined as operating income plus depreciation,
     amortization of goodwill, amortization of intangibles and net periodic
     postretirement benefits expense and is a key financial measure but should
     not be construed as an alternative to operating income or cash flows from
     operating activities (as determined in accordance with generally accepted
     accounting principles). Adjusted EBITDA is also one of the financial
     measures by which the Company's compliance with its covenants is calculated
     under its debt agreements. The Company believes that Adjusted EBITDA is a
     useful supplement to net income (loss) and other consolidated income
     statement data in understanding cash flows generated from operations that
     are available for taxes, debt service and capital expenditures. However,
     the Company's method of computation may or may not be comparable to other
     similarly titled measures of other companies. In addition, Adjusted EBITDA
     is not necessarily indicative of amounts that may be available for
     discretionary uses and does not reflect any legal or contractual
     restrictions on the Company's use of funds.
 
(10) Adjusted EBITDA with cost savings represents the pro forma 1997 Adjusted
     EBITDA plus $10.2 million of anticipated cost savings and operational
     enhancements. The components of these cost savings and operational
     enhancements are set forth below.

                                  RISK FACTORS
 
     In addition to the other information set forth herein, prospective
investors should carefully consider the following information in evaluating the
Company and its business before making an investment in the New Debentures.
 
CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS
 
     The information herein contains forward-looking statements that involve a
number of risks and uncertainties. A number of factors could cause actual
results, performance, achievements of the Company, or industry results to be
materially different from any future results, performance or achievements
expressed or implied by such forward-looking statements. These factors include,
but are not limited to: the competitive environment in the cutting and welding
industry in general and in the Company's specific market areas; changes in
prevailing interest rates and the availability of and terms of financing to fund
the anticipated growth of the Company's business; inflation; changes in costs of
goods and services; economic conditions in general and in the Company's specific
market areas; changes in or failure to comply with federal, state and/or local
government regulations; liability and other claims asserted against the Company;
changes in operating strategy or development plans; the ability to attract and
retain qualified personnel; the significant indebtedness of the Company; labor
disturbances; changes in the Company's acquisition and capital expenditure
plans; and other factors referenced herein. In addition, such forward-looking
statements are necessarily dependent upon assumptions, estimates and dates that
may be incorrect or imprecise and involve known and unknown risks uncertainties
and other factors. Accordingly, any forward-looking statements included herein
do not purport to be predictions of future events or circumstances and may not
be realized. Forward-looking statements can be identified by, among other
things, the use of forward-looking terminology such as "believes," "expects,"
"may," "will," "should," "seeks," "pro forma" or "anticipates," "intends" or the
negative of any thereof, or other variations thereon or comparable terminology,
or by discussions of strategy or intentions. Given these uncertainties,
prospective investors are cautioned not to place undue reliance on such
forward-looking statements. The Company disclaims any obligations to update any
such factors or to publicly announce the results of any revisions to any of the
forward-looking statements contained herein to reflect future events or
developments.
 
SUBSTANTIAL LEVERAGE; LIQUIDITY; STOCKHOLDER'S DEFICIT
 
     In connection with the Merger and the Merger Financing, including the
application of the proceeds therefrom, the Company incurred a significant amount
of indebtedness. As of March 31, 1998, after giving pro forma effect to the
Merger, including the Merger Financing and the application of the proceeds
thereof, the Company would have had (i) total consolidated indebtedness of
approximately $682.0 million, (ii) $66.8 million of additional borrowings
available under the New Credit Facility and (iii) a stockholder's deficit of
$475.4 million. In addition, subject to the restrictions in the Indenture, the
New Credit Facility and the Indenture pursuant to which the Senior Subordinated
Notes are being issued (the "Notes Indenture"), the Company may incur
significant additional indebtedness, which may be secured, from time to time.
 
     The level of the Company's indebtedness could have important consequences
to the Company, including: (i) limiting cash flow available for general
corporate purposes, including acquisitions, because a substantial portion of the
Company's cash flow from operations must be dedicated to debt service; (ii)
limiting the Company's ability to obtain additional debt financing in the future
for working capital, capital expenditures or acquisitions; (iii) limiting the
Company's flexibility in reacting to competitive and other changes in the
industry and economic conditions generally; and (iv) exposing the Company to
risks inherent in interest rate fluctuations because certain of the Company's
borrowings may be at variable rates of interest, which could result in higher
interest expense in the event of increases in interest rates.
 
     The Company's ability to make scheduled payments of principal of, to pay
interest on or to refinance its indebtedness and to satisfy its other debt
obligations will depend upon its future operating performance, which will be
affected by general economic, financial, competitive, legislative, regulatory,
business and other factors beyond its control. The Company anticipates that its
operating cash flow, together with borrowings under the
 
                                       15
<PAGE>   17
 
New Credit Facility, will be sufficient to meet its anticipated future operating
expenses, capital expenditures and to service its debt requirements as they
become due. However, if the Company's future operating cash flows are less than
currently anticipated it may be forced, in order to meet its debt service
obligations, to reduce or delay acquisitions or capital expenditures, sell
assets or reduce operating expenses, including, but not limited to, investment
spending such as selling and marketing expenses, expenditures on management
information systems and expenditures on new products. If the Company were unable
to meet its debt service obligations, it could attempt to restructure or
refinance its indebtedness or to seek additional equity capital. There can be no
assurance that the Company will be able to effect any of the foregoing on
satisfactory terms, if at all. In addition, subject to the restrictions and
limitations contained in the agreements relating to the Merger Financing, the
Company may incur significant additional indebtedness to finance future
acquisitions, which could adversely affect the Company's operating cash flows
and its ability to service its indebtedness. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."
 
LIMITATIONS ON ACCESS TO CASH FLOW OF SUBSIDIARIES; HOLDING COMPANY STRUCTURE
 
     The Issuer is a holding company, and its ability to pay interest on the New
Debentures is dependent upon the receipt of dividends from its direct and
indirect subsidiaries. The Issuer does not have, and may not in the future have,
any assets other than ownership interests in Thermadyne LLC. Thermadyne LLC and
its subsidiaries are parties to the New Credit Facility and the Notes Indenture,
each of which imposes substantial restrictions on Thermadyne LLC's ability to
pay dividends to the Issuer. Any payment of dividends will be subject to the
satisfaction of certain financial conditions set forth in the Notes Indenture
and the New Credit Facility. The ability of Thermadyne LLC and its subsidiaries
to comply with such conditions in the Notes Indenture may be affected by events
that are beyond the control of the Issuer. The breach of any such conditions
could result in a default under the Notes Indenture and/or the New Credit
Facility, and in the event of any such default, the holders of the Senior
Subordinated Notes or the lenders under the New Credit Facility could elect to
accelerate the maturity of all the Senior Subordinated Notes or the loans under
such facility. If the maturity of the Senior Subordinated Notes or the loans
under the New Credit Facility were to be accelerated, all such outstanding debt
would be required to be paid in full before Thermadyne LLC or its subsidiaries
would be permitted to distribute any assets or cash to the Issuer. There can be
no assurance that the assets of the Company would be sufficient to repay all of
such outstanding debt and to meet its obligations under the Indenture. Future
borrowings by Thermadyne LLC can be expected to contain restrictions or
prohibitions on the payment of dividends by such subsidiaries to the Issuer. In
addition, under Delaware law, a limited liability company may not make
distributions to its members if, after giving effect thereto, the liabilities of
the limited liability company would exceed the fair value of its assets. The
Issuer cannot predict what the value of its subsidiaries' assets or the amount
of their liabilities will be in the future and whether such values or amounts
will permit the payment of distributions to the Issuer. Accordingly, there can
be no assurance that the Issuer will be able to pay its debt service obligations
on the New Debentures. As a result of the holding company structure of the
Company, the Holders of the New Debentures are structurally junior to all
creditors of the Issuer's subsidiaries, except to the extent that the Issuer is
itself recognized as a creditor of any such subsidiary, in which case the claims
of the Issuer would still be subordinate to any security in the assets of such
subsidiary and any indebtedness of such subsidiary senior to that held by the
Issuer. In the event of insolvency, liquidation, reorganization, dissolution or
other winding-up of the Issuer's subsidiaries, the Issuer will not receive any
funds available to pay to creditors of the subsidiaries. As of March 31, 1998,
on a pro forma basis after giving effect to the Merger and Merger Financing,
including the application of net proceeds therefrom, the aggregate amount of
indebtedness and other obligations of the Issuer's subsidiaries (including trade
payables) would have been approximately $733.2 million.
 
POSSIBLE INABILITY TO REPURCHASE NEW DEBENTURES UPON CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, each Holder of New Debentures
will have the right to require the Issuer to repurchase all or any part of such
Holder's New Debentures at an offer price in cash equal to 101% of the aggregate
principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages, if any, thereon to the date of repurchase. No assurance can be given
that the Issuer will have
 
                                       16
<PAGE>   18
 
sufficient resources to satisfy its repurchase obligation with respect to the
New Debentures following a Change of Control. See "Description of New
Debentures -- Repurchase at the Option of Holders -- Change of Control."
 
     The Issuer does not have, and may not in the future have, any assets other
than ownership interests in Thermadyne LLC. As a result, the Issuer's ability to
repurchase all or any part of the New Debentures upon the occurrence of a Change
of Control will be dependent upon the receipt of dividends or other
distributions from its direct and indirect subsidiaries. The New Credit Facility
and the Notes Indenture restrict Thermadyne LLC from paying dividends and making
any other distributions to the Issuer. If the Issuer does not obtain the consent
of the lenders under agreements governing outstanding Indebtedness of its
Subsidiaries, including under the New Credit Facility and the Notes Indenture,
to permit the repurchase of the New Debentures or does not refinance such
Indebtedness, the Issuer will likely not have the financial resources to
purchase New Debentures upon the occurrence of a Change of Control and the
Issuer's subsidiaries will be restricted by the terms of such Indebtedness from
paying dividends to the Issuer or otherwise lending or distributing funds to the
Issuer for the purpose of such purchase. In any event, there can be no assurance
that the Issuer's subsidiaries will have the resources available to pay such
dividend or make any such distribution. Furthermore, the New Credit Facility
provides that certain change of control events will constitute a default
thereunder and the Notes Indenture provides that, in the event of a Change of
Control, Thermadyne LLC and Thermadyne Capital will be required to offer to
repurchase the Senior Subordinated Notes at the price specified therefor. The
Issuer's failure to make a Change of Control offer when required or to purchase
tendered New Debentures when tendered would constitute an Event of Default under
the Indenture. See "Description of New Debentures."
 
ORIGINAL ISSUE DISCOUNT; LIMITATIONS ON HOLDERS' CLAIMS
 
     The Debentures were issued at a substantial original issue discount from
their principal amount at maturity. Consequently, participants in the Exchange
Offer will be required to include amounts in gross income for federal income tax
purposes in advance of receipt of the cash payments to which the income is
attributable.
 
     Under the Indenture, in the event of an acceleration of the maturity of the
New Debentures upon the occurrence of an Event of Default, the Holders of the
New Debentures may be entitled to recover only the amount which may be declared
due and payable pursuant to the Indenture, which will be less than the principal
amount at maturity of such New Debentures. See "Description of the New
Debentures -- Events of Default and Remedies."
 
     If a bankruptcy case is commenced by or against the Issuer under the
Bankruptcy Code, the claim of a Holder of New Debentures with respect to the
principal amount thereof may be limited to an amount equal to the sum of (i) the
issue price of the New Debentures and (ii) that portion of the original issue
discount (as determined on the basis of such issue price) which is not deemed to
constitute "unmatured interest" for purposes of the Bankruptcy Code (as defined
herein). Accordingly, Holders of the New Debentures under such circumstances
may, even if sufficient funds are available, receive a lesser amount than they
would be entitled to under the express terms of the Indenture. In addition,
there can be no assurance that a bankruptcy court would compute the accrual of
interest under the same rules as those used for the calculation of original
issue discount under federal income tax law and, accordingly, a Holder might be
required to recognize gain or loss in the event of a distribution related to
such a bankruptcy case.
 
CONTROL BY THE DLJMB FUNDS
 
     Approximately 80.6% of the outstanding shares of Holdings Common Stock is
held by the DLJMB Funds. As a result of their stock ownership, the DLJMB Funds
control Holdings and have the power to elect a majority of its directors,
appoint new management and approve any action requiring the approval of the
holders of Holdings Common Stock, including adopting certain amendments to
Holdings' certificate of incorporation and approving mergers or sales of all or
substantially all of Holdings' assets. The directors elected by the DLJMB Funds
will have the authority to effect decisions affecting the capital structure of
 
                                       17
<PAGE>   19
 
Holdings, including the issuance of additional capital stock, the implementation
of stock repurchase programs and the declaration of dividends. The interests of
the DLJMB Funds may differ from the interests of other holders of Holdings
Common Stock.
 
     The general partners of each of the DLJMB Funds are affiliates or employees
of Donaldson, Lufkin & Jenrette, Inc. ("DLJ, Inc."). DLJ Capital Funding, which
acted as syndication agent for the New Credit Facility in connection with the
Merger, is also an affiliate of DLJ, Inc. DLJSC, which placed the Senior
Subordinated Notes and the Debentures, is also an affiliate of DLJ, Inc.
 
     The existence of a controlling stockholder of the Company is likely to have
the effect of making it more difficult for a third party to acquire, or of
discouraging a third party from seeking to acquire, a majority of the
outstanding Holdings Common Stock. A third party would be required to negotiate
any such transaction with the DLJMB Funds and the interests of the DLJMB Funds
may be different from the interests of other Company stockholders.
 
ACQUISITION GROWTH STRATEGY; MANAGEMENT AND FUNDING OF GROWTH
 
     The Company has historically pursued an aggressive acquisition strategy,
completing six acquisitions from September 13, 1994 to December 31, 1997, and
expects to continue to pursue such a strategy to promote its growth. There are
various risks associated with pursuing a growth strategy of this nature. Any
future growth of the Company will require the Company to manage its expanding
domestic and international operations, integrate new businesses and adapt its
operational and financial systems to respond to changes in its business
environment, while maintaining a competitive cost structure. The acquisition
strategy of the Company will continue to place significant demands on the
Company and its management to improve the Company's operational, financial and
management information systems, to develop further the management skills of the
Company's managers and supervisors, and to continue to retain, train, motivate
and effectively manage the Company's employees. The failure of the Company to
manage its prior or any future growth effectively could have a material adverse
effect on the Company. There also can be no assurance that suitable acquisition
candidates will be available or that acquisitions can be completed on reasonable
terms.
 
     Additionally, the Company's ability to maintain and increase its revenue
base and to respond to shifts in customer demand and changes in industry trends
will be partially dependent on its ability to generate sufficient cash flow or
obtain sufficient capital for the purpose of, among other things, financing
acquisitions, satisfying customer contractual requirements and financing
infrastructure growth. There can be no assurance that the Company will be able
to generate sufficient cash flow or that financing will be available on
acceptable terms (or permitted to be incurred under the terms of the Merger
Financing and any future indebtedness) to fund the Company's future growth.
 
CYCLICALITY AND MATURITY OF THE CUTTING AND WELDING INDUSTRY
 
     The cutting and welding industry in the United States is a mature industry
that is cyclical in nature. The substitution of plastic, concrete and other
materials impacts the use of fabricated metal parts in many products and
structures. Increased offshore manufacturing by United States companies has
contributed to slow growth rates in the domestic manufacturing industry and in
turn has led to slower growth in the United States cutting and welding industry.
During periods of economic expansion the cutting and welding industry has grown
at double digit rates but has experienced contraction during periods of slowing
industrial activity. There can be no assurance that during future periods of
economic expansion the cutting and welding industry will experience the same
growth rates as it has in the past. Although the Company believes that its
exposure to cyclical downturns is moderated by its broad customer base and the
diversity of the industries it serves, cyclical downturns could have an adverse
effect on period-to-period results.
 
INTERNATIONAL MARKETS
 
     The Company's growth strategy includes increasing the marketing of existing
products into Europe, Asia, Latin America and other developing economies.
However, there can be no assurance that the Company will be successful in its
expansion efforts.
 
                                       18
<PAGE>   20
 
     Approximately 42% of the Company's net sales in 1997 (including its United
States third party export sales) were made to purchasers located in foreign
countries. Because of its foreign operations, the Company's business is subject
to the currency risks of doing business abroad, including exchange rate
fluctuations and limits on repatriation of funds.
 
     Additionally, as a result of the current downturn in the Asian economy,
there may be a decrease in infrastructure development in the Asian region or an
overall worldwide contraction of industrial development. The impact of decreased
development could have a material adverse effect on the Company's business,
financial condition or results of operations.
 
     Further, many developing economies have a significant degree of political
and economic uncertainty. Social unrest, the absence of trained labor pools and
the uncertainty of entering into joint ventures or other partnership
arrangements with local organizations have slowed business activities in some
large developing economies. The political and economic uncertainties present in
these promising growth markets may adversely impact the Company's ability to
implement and achieve its foreign growth objectives.
 
COMPETITION
 
     The cutting and welding industry is highly competitive. While the Company
believes it is one of only a few worldwide broad line manufacturers of both
cutting and welding equipment and consumable products, the Company competes in
each of its businesses with other broad line manufacturers and numerous smaller
competitors specializing in particular products.
 
     While the Company has historically experienced little direct foreign
competition in the United States market, fluctuations in the value of the United
States dollar against other currencies could make the United States market more
attractive to foreign exporters.
 
     The Company currently experiences substantial competition in the foreign
markets in which it competes.
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's continued success depends, to a large extent, upon the
efforts and abilities of key managerial employees, particularly Holdings'
executive officers. See "Management." Although Holdings has employment
agreements with all of its executive officers, there can be no assurance that
such persons will remain in the employ of the Company. Competition for qualified
management personnel in the industry is intense. The loss of the services of
certain of these key employees or the failure to retain qualified employees when
needed could have a material adverse effect on the Company's business, financial
condition or results of operations. See "Executive Compensation -- Employment
Contracts." The Company does not currently maintain key man life insurance.
 
ENVIRONMENTAL MATTERS
 
     The Company's operations are subject to federal, state, local and foreign
laws and regulations relating to the storage, handling, generation, treatment,
emission, release, discharge and disposal of certain substances and wastes. As a
result, the Company is involved from time to time in administrative or legal
proceedings relating to environmental matters and has in the past and will
continue to incur capital costs and other expenditures relating to environmental
matters. Liability under environmental laws may be imposed on current and prior
owners and operators of property or businesses without regard to fault or to
knowledge about the condition or action causing the liability. The Company may
be required to incur costs relating to the remediation of properties, including
properties at which the Company disposes of waste, and environmental conditions
could lead to claims for personal injury, property damage or damages to natural
resources. The Company is aware of environmental conditions at certain
properties which it now or previously owned or leased which are undergoing
remediation and the Company has in the past and may in the future be named a
potentially responsible party ("PRP") at off-site disposal sites to which it has
sent waste.
 
     The Company believes, based on current information, that any costs it may
incur relating to environmental matters will not have a material adverse effect
on its business, financial condition or its result of operations.
 
                                       19
<PAGE>   21
 
There can be no assurance, however, that the Company will not incur significant
fines, penalties or other liabilities associated with noncompliance or clean-up
liabilities or that future events, such as changes in laws or the interpretation
thereof, the development of new facts or the failure of other PRPs to pay their
share will not cause the Company to incur additional costs that could have a
material adverse effect on its business, financial condition or results of
operations. See "Business -- Legal Proceedings and Environmental Matters."
 
ABSENCE OF PUBLIC MARKET
 
     The Old Debentures were issued on May 22, 1998, and the Company is not
aware that any active trading market for the Old Debentures has developed. The
Company does not intend to apply for a listing of the New Debentures on a
securities exchange or on any automated dealer quotation system. If any of the
New Debentures are traded after their issuance, they may trade at a discount
from their initial offering price, depending upon prevailing interest rates, the
market for similar securities and other factors, including general economic
conditions and the financial condition, performance of, and prospects for, the
Company. There can be no assurance as to the development of any market or
liquidity of any market that may develop for the New Debentures. The liquidity
of, and trading markets for, the New Debentures may also be adversely affected
by declines in the market for high yield securities generally.
 
YEAR 2000
 
     The year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of the Company's
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices, or
engage in similar normal business activities. The Company believes that its
internal systems are Year 2000 compliant or will be upgraded or replaced in
connection with previously planned changes to information systems prior to the
need to comply with Year 2000 requirements. However, the Company is uncertain as
to the extent its customers and vendors may be affected by Year 2000 issues that
require commitment of significant resources and may cause disruptions in the
customers' and vendors' businesses.

                                USE OF PROCEEDS
 
     The Company will not receive any cash proceeds from the exchange pursuant
to the Exchange Offer.
 
     The proceeds from the sale of the Old Debentures, after deducting expenses
of the Offering, including discounts to the Initial Purchaser, were
approximately $90.8 million. The proceeds from the Offering, together with the
borrowings under the New Credit Facility, the DLJMB Equity Investment, and the
issuance of the Senior Subordinated Notes were used to finance the conversion
into cash of approximately 95.7% of the shares of Holdings Common Stock, to
refinance the outstanding indebtedness of the Company, fund payments of the
Option Cash Proceeds and the ESPP Cash Proceeds, and finance the expenses and
fees incurred in connection with the Merger. See "The Merger and Merger
Financing." Approximately $547 million of the proceeds to Thermadyne LLC from
the initial borrowings under the New Credit Facility and the Senior Subordinated
Notes was dividended to Holdings to fund a portion of the Cash Merger
Consideration (as defined herein) and fees and expenses of Holdings in
connection therewith.

                            SELECTED FINANCIAL DATA
 
     The selected financial data for and as of each of the years in the
five-year period ended December 31, 1997 set forth below have been derived from
the audited Consolidated Financial Statements of the Company and its
predecessor. The historical financial data for the three-month periods ended
March 31, 1998 and 1997 are derived from unaudited financial statements. The
unaudited financial statements include all adjustments, consisting only of
normal recurring adjustments, which the Company considers necessary for a fair
presentation of the financial position and the results of operations for these
periods. Operating results for the three-month period ended March 31, 1998 are
not necessarily indicative of the results that may be expected for the entire
year ending December 31, 1998. The data should be read in conjunction with the
historical consolidated financial statements of the Company and its predecessor,
and the related notes thereafter, set forth elsewhere herein. In 1996, Holdings
announced plans to sell, and in 1997 consummated the sale of, its wear
resistance business; in late 1995, Holdings announced its plans to sell, and in
1996 consummated the sale of, its gas containment and floor maintenance
businesses. These businesses are accounted for as discontinued operations in
Holdings' Consolidated Financial Statements. The selected financial data should
be read in conjunction with "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and Holdings' Consolidated Financial
Statements and Notes thereto, in each case included elsewhere herein.

    not be construed as an alternative to operating income or cash flows from
    operating activities (as determined in accordance with generally accepted
    accounting principles). Adjusted EBITDA is also one of the financial
    measures by which the Company's compliance with its covenants is calculated
    under its debt agreements. The Company believes that Adjusted EBITDA is a
    useful supplement to net income (loss) and other consolidated income
    statement data in understanding cash flows generated from operations that
    are available for taxes, debt service and capital expenditures. However, the
    Company's method of computation may or may not be comparable to other
    similarly titled measures of other companies. In addition, Adjusted EBITDA
    is not necessarily indicative of amounts that may be available for
    discretionary uses and does not reflect any legal or contractual
    restrictions on the Company's use of funds.
 
(9) For purposes of calculating the ratio of earnings to fixed charges, earnings
    consist of income before income taxes plus fixed charges. Fixed charges
    consist of interest expense, amortization of deferred financing costs and
    one-third of the rent expense from operating leases, which management
    believes is a reasonable approximation of the interest component of rent
    expense. Earnings were not sufficient to cover fixed charges by $52.8
    million, $80.8 million, $123.3 million and $63.5 million for the fiscal
    years ended December 31, 1993, 1994, 1995 and 1996, respectively.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with Holdings'
Consolidated Financial Statements including the notes thereto.
 
     This discussion contains forward-looking statements within the meaning of
the Private Securities Litigation Reform Act of 1995 which involve risks and
uncertainties. The Company's actual results may differ significantly from the
results discussed in the forward-looking statements. Factors that might cause
such a difference include, but are not limited to, those discussed in "Risk
Factors."
 
OVERVIEW
 
     Thermadyne, through its subsidiaries, is engaged in the design, manufacture
and distribution of cutting and welding products and accessories. Since 1993,
the Company has embarked on a strategy designed to focus its business
exclusively on the cutting and welding industry and enhance the Company's market
position within that industry.
 
     The Company divested three non-core businesses: the Coyne Cylinder Company
(1996), the Clarke floor maintenance business (1996) and the Deloro Stellite
wear resistance business (1997). In addition, since 1993, the Company acquired
six cutting and welding businesses, which businesses collectively generated
approximately $169 million in annual revenue at the respective times of
acquisition, in order to broaden the Company's product offerings and expand the
Company's worldwide geographic coverage. The acquisitions of Modern Engineering
Company (1994), C&G Systems Inc. (1995), Arcsys (1997), and Woodland (1997) all
added additional or complementary product lines to the Company's product
offering. The acquisition of Cigweld (1996), an Australian based manufacturer of
welding products, provided the Company with new product offerings as well as a
significant market position in Australia and New Zealand and positioned the
Company to effectively compete in the growing Asian market. The acquisition of
GenSet (1997), an Italian manufacturer of engine-driven welders, extended the
Company's product line globally and increased the Company's European presence.
Thermadyne plans to continue its focused acquisition strategy to acquire
businesses that augment its product offering and/or geographic coverage.
 
     The Company's revenue is now generated entirely by the sale of cutting and
welding equipment, accessories and consumables. Consumables include tips,
electrodes, parts and other products that are required to be periodically
replaced. Consumable sales accounted for over 40% of total revenue in 1997 and
are expected to continue generating a significant percentage of revenue in the
future.
 
     As a result of the Merger, the Company incurred various costs in connection
with consummating the transaction. See Note 2 to the Unaudited Condensed
Consolidated Pro Forma Statement of Operations for a more detailed explanation
of these expenses. While the exact timing, nature and amount of these costs have
not yet been fully determined, the Company anticipates that a significant
one-time pretax charge will be recorded in its second fiscal quarter. As a
result of the foregoing, the Company expects to record a significant net loss in
its second fiscal quarter. Because this loss will result directly from the
one-time charge incurred in connection with the Merger, and this charge will be
funded entirely through the proceeds of the Merger Financing, the Company does
not expect this loss to materially impact its liquidity, ongoing operations or
market position.
 
COST REDUCTION INITIATIVES
 
     Thermadyne strives to continually improve manufacturing efficiencies and
reduce unit costs. In December 1997, the Company implemented a cost reduction
program that includes the following principal elements: (i) vendor
rationalization and consolidation; (ii) manufacturing process and productivity
improvements and product design changes; (iii) personnel rationalization and
expense reductions; (iv) advertising and trade show expense reductions; (v)
aircraft, charter and other travel expense reductions; and (vi) elimination of
the annual sales meeting. These cost reduction initiatives are expected to
generate approximately $10 million in savings on an annualized basis. In
addition, the Company has initiated the implementation of a new global
 
                                       25
<PAGE>   27
 
information system that is designed to allow the Company to further integrate
administrative functions and improve information flow across business unit
lines.
 
RESULTS OF OPERATIONS
 
     The following discussion of results of operations is presented for the
fiscal years ended December 31, 1997, 1996 and 1995 and the three months ended
March 31, 1998 and 1997. The results of operations of the Company's predecessor,
Holdings, include the operations of C&G, Cigweld, GenSet, Arcsys and Woodland
from their respective dates of acquisition.
 
  THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO THREE MONTHS ENDED MARCH 31,
1997
 
  Net Sales
 
     Net sales were $131.8 million for the three months ended March 31, 1998
compared to $117.8 million for the three months ended March 31, 1997, an
increase of 12.0%. Domestic sales for the first three months of 1998 were up
20.3% (10.5% excluding acquisitions) over the first three months of 1997.
International sales increased approximately 1.0% overall despite the continuing
economic turmoil in Asia. Europe, Latin America and the Middle East regions all
recorded significant increases over the prior year.
 
  Costs and Expenses
 
     Cost of goods sold as a percentage of sales for the quarter ended March 31,
1998 was 62.0% compared to 59.7% for the quarter ended March 31, 1997. This
increase is the result of (i) recent acquisitions, which generally carry a
somewhat lower average gross margin than the Company's existing businesses, and
(ii) sales mix, as the Company expanded its product offering including items in
more price-competitive markets.
 
     Selling, general and administrative expenses were $27.1 million for the
first three months of 1998, an increase of $0.8 million, or 3.0% over the first
three months of 1997. As a percentage of sales, selling, general and
administrative expenses were 20.5% for the three months ended March 31, 1998 and
22.3% for the three months ended March 31, 1997. This improvement is due in part
to the Company's growth in sales as a portion of its costs are fixed in nature,
as well as the realization of savings from a cost reduction program the Company
initiated in December 1997.
 
     Interest expense decreased from $11.5 million in the first quarter of 1997
to $10.8 million in the first quarter of 1998, a decrease of $0.7 million or
6.1%. This decrease is largely the result of lower debt levels in 1998 compared
to 1997.
 
     Income tax provision was $4.6 million on pre-tax income of $10.4 million
for the three months ended March 31, 1998, compared to an income tax provision
of $3.0 million on pre-tax income of $6.9 million for the three months ended
March 31, 1997.
 
  Adjusted EBITDA
 
     Adjusted EBITDA was $26.5 million for the quarter ended March 31, 1998,
compared to $24.0 million for the quarter ended March 31, 1997, an increase of
$2.5 million or 10.5%.
 
  FISCAL 1997 COMPARED TO FISCAL 1996
 
  Net Sales
 
     Net sales from continuing operations for the year ended December 31, 1997
were $520.4 million, compared to net sales of $439.7 million for the year ended
December 31, 1996, an increase of $80.7 million, or 18.4%. Domestic and
international sales increased 12.0% and 28.3%, respectively in 1997. Included in
net sales for the year ended December 31, 1997 are sales of $32.9 million
related to GenSet, which was acquired effective February 1, 1997, $5.6 million
related to Arcsys, which was acquired on September 26, 1997 and $0.2 million
related to Woodland, which was acquired on November 25, 1997. Excluding sales
from these

acquired companies, net sales from continuing operations increased $42.0
million, or 9.6%. New product introductions and the addition of products through
acquisition have been the most significant growth factors in domestic sales.
Success with new marketing programs and with sales through alternate channels
have also contributed to this increase. Sales in international markets have
increased as a result of strategic initiatives in Asia and Latin America, and
the addition of sales personnel.
 
  Costs and Expenses
 
     Cost of goods sold from continuing operations as a percentage of sales for
the year ended December 31, 1997 was 61.5% compared to 59.1% for the year ended
December 31, 1996. This change is largely due to the 1997 acquisitions as these
new product lines have lower average gross margins than the blended margin in
the Company's existing businesses. Excluding the effect of the 1997
acquisitions, cost of goods sold as a percentage of sales would have been 59.9%.
 
     Selling, general and administrative expenses from continuing operations
increased 15.4% to $110.7 million for the year ended December 31, 1997 from
$95.9 million for the year ended December 31, 1996. The 1997 acquisitions added
$4.6 million of this $14.8 million increase. The remainder of this increase is
mostly the result of spending in Asia and Latin America related to internal
infrastructure and business development as the Company pursues increased market
share in these regions. As a percentage of sales, selling, general and
administrative expenses from continuing operations decreased to 21.3% for the
year ended December 31, 1997 from 21.8% for the year ended December 31, 1996.
 
     Amortization of goodwill decreased $81.4 million to $1.6 million for the
year ended December 31, 1997 from $83.0 million for the year ended December 31,
1996. Goodwill amortization in 1997 relates to acquisitions since the Company's
1994 financial reorganization. In 1996, goodwill recorded in connection with the
reorganization was reduced, in part, by the initial recognition of certain
deferred tax assets existing on the effective date of the Company's
comprehensive financial restructuring and the remaining amount associated with
the reorganization became fully amortized. Amortization of other intangibles
decreased from $12.4 million to $6.8 million for the years ended December 31,
1996 and 1997, respectively. This $5.6 million, or 45.3%, decrease results from
the initial recognition of the net deferred tax asset as well as adjustments
during 1997 resulting from the recognition of net operating loss carryforward
benefits and the sale of the wear resistance business.
 
     Interest expense was essentially the same for 1997 as in 1996, even though
the Company's overall debt level decreased $63.3 million over the course of the
year. This is due to the acquisition of GenSet in February 1997 which resulted
in a higher overall debt balance the first nine months of the year. Cash
proceeds from the sale of discontinued operations were used to reduce debt at
the end of the third quarter of 1997.
 
     Income tax expense was $13.5 million for the year ended December 31, 1997
compared to an income tax benefit of $0.5 million for the year ended December
31, 1996. The income tax benefit recorded in the fourth quarter of 1996 includes
a $13.8 million income tax benefit resulting from the initial recognition of the
Company's net deferred tax asset. The Company's decision to record the net
deferred tax asset was based on an analysis of actual taxable income in the
available carryback period and taxable income expected to be generated in the
succeeding three years. Based on this analysis, the Company believes that it is
more likely than not that the recorded net deferred tax asset will be realized.
 
  Adjusted EBITDA
 
     Adjusted EBITDA from continuing operations was $102.1 million and $95.7
million for the years ended December 31, 1997 and 1996, respectively. As a
percentage of sales, Adjusted EBITDA was 19.6% for the year ended December 31,
1997 compared to 21.8% for the year ended December 31, 1996. For a description
of the term "Adjusted EBITDA", see Note 9 to "Summary -- Summary Historical and
Unaudited Pro Forma Condensed Consolidated Financial Information."

  Recent Accounting Pronouncements
 
     As of January 1, 1998, the Company adopted FASB Statement 130, "Reporting
Comprehensive Income" ("Statement 130"). Statement 130 establishes new rules for
the reporting and display of comprehensive income and its components; however,
the adoption of this Statement had no impact on the Company's net income or
shareholders' equity. Statement 130 requires foreign currency translation
adjustments, which prior to adoption were reported separately in shareholders'
equity, to be included in other comprehensive income. Prior year financial
statements have been reclassified to conform to the requirements of Statement
130.
 
     In June 1997, the FASB issued Statement No. 131, "Disclosures about
Segments of an Enterprise and Related Information" ("FASB 131"), which requires
publicly-held companies to report financial and descriptive information about
its operating segments in financial statements issued to shareholders for
interim and annual periods. The statement also requires additional disclosures
with respect to products and services, geographical areas of operations, and
major customers. FASB 131 is effective for fiscal years beginning after December
15, 1997 and requires restatement of earlier periods presented. The Company is
evaluating the impact of adopting this standard.
 
  FISCAL 1996 COMPARED TO FISCAL 1995
 
  Net Sales
 
     Net sales from continuing operations were $439.7 million for the year ended
December 31, 1996, representing an increase of $123.0 million, or 38.8%, over
comparable net sales for the year ended December 31, 1995. This increase
includes $100.2 million related to Cigweld, which was acquired effective
February 1, 1996. Excluding the effects of Cigweld, net sales from continuing
operations increased $22.8 million, or 7.2%, over 1995. This growth was realized
over all of the Company's key product lines and was the result of emphasis on
new product development, sales force expansion and increasing the Company's
international presence. The Company's overall sales increase came from domestic
growth of 7.5% and an increase in international business of 154.4% including the
effects of Cigweld. Sales have increased in all the Company's major
international markets, particularly Asia and Latin America which are two of the
key geographic areas the Company has targeted for growth.
 
  Costs and Expenses
 
     Cost of goods sold from continuing operations for the year ended December
31, 1996 was 59.1% of sales, which compares to 55.5% of sales for the year ended
December 31, 1995. This increase in percent of sales was expected upon
completion of the acquisition of Cigweld as the average gross margin on Cigweld
products is lower than the Company's existing businesses' blended margin.
Excluding the effect of Cigweld, cost of goods sold would have been 54.6% of
sales with the improvement over 1995 due primarily to a more favorable sales
mix.
 
     Selling, general and administrative expenses from continuing operations
increased $21.2 million, or 28.4%, to $95.9 million for the year ended December
31, 1996. The acquisition of Cigweld accounts for $17.2 million of this
increase. As a percentage of sales, selling, general and administrative expenses
were 21.8% for the 12 months ended December 31, 1996 compared to 23.6% for the
twelve months ended December 31, 1995.
 
     Amortization of other intangibles has decreased from 1995 due to the early
adoption of Financial Accounting Standards Board Statement No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of," during the fourth quarter of 1995, which resulted in a writedown of those
assets of approximately $33.0 million.
 
     Interest expense increased $4.4 million to $45.7 million for the year ended
December 31, 1996 from $41.3 million for the year ended December 31, 1995. This
increase results primarily from debt incurred in the acquisition of Cigweld.
 
                                       28
<PAGE>   30
 
     A tax benefit of $0.5 million was reported for the year ended December 31,
1996 compared to tax expense of $8.5 million reported for the year ended
December 31, 1995. In the fourth quarter of 1996, the Company reevaluated the
realizability of its net deferred tax asset, and consequently, recorded a $13.8
million reduction in income tax expense. The Company's decision to record the
net deferred tax asset was based on an analysis of actual taxable income in the
available carryback period and taxable income expected to be generated in the
succeeding three years. Based on this analysis, the Company believes that it is
more likely than not that the recorded net deferred tax asset will be realized.
 
  Adjusted EBITDA
 
     Adjusted EBITDA from continuing operations was $95.7 million for the twelve
months ended December 31, 1996 compared to $74.6 million for the twelve months
ended December 31, 1995. As a percentage of sales, Adjusted EBITDA was 21.8% for
the year ended December 31, 1996, compared to 23.6% for 1995. Excluding Cigweld
the Adjusted EBITDA percentage for 1996 would have been 24.8%.
 
  Discontinued Operations
 
     Excluding the effects of accounting for the wear resistance business as
discontinued operations, net sales and Adjusted EBITDA for the twelve months
ended December 31, 1996, were $546.1 million and $110.5 million, respectively,
increases of 31.9% and 24.4%, respectively, over the twelve months ended
December 31, 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Working Capital and Cash Flows. Cash used in operating activities was $9.1
million for the first quarter of 1998, a decrease of $12.0 million from the
first quarter of 1997, in which cash flow from operations provided $2.9 million.
This use of cash by operating activities is the result of a net increase in
operating assets and liabilities of $12.9 million. Net cash used in investing
activities decreased from $22.2 million in the first quarter of 1997 to $4.7
million in the first quarter of 1998. Cash used for acquisitions decreased $27.1
million and was offset by an increase in capital expenditures of $1.4 million
and a decrease in cash provided by other assets of $8.9 million. Cash provided
by financing activities decreased $12.9 million to $12.6 million for the quarter
ended March 31, 1998 from $25.4 million for the quarter ended March 31, 1997.
Net borrowings of long-term debt decreased $12.0 million in a comparison of
these same periods. In addition, the accounts receivable securitization program
provided $4.3 million less in the first three months of 1998 compared to 1997,
while financing activities of discontinued operations and other financing
activities used $1.2 million and $2.0 million less in the first quarter of 1998,
respectively.
 
     Cash provided by operating activities was $15.0 million for the year ended
December 31, 1997 compared to $21.5 million for the year ended December 31,
1996. This decrease in cash provided by operating activities is the result of a
net increase in operating assets and liabilities in 1997 compared to 1996 of
$7.3 million, partially offset by an increase in earnings (adjusted for noncash
expenses) of $0.8 million in 1997 over 1996. Net cash provided by investing
activities was $36.8 million in 1997 compared to $18.7 million in 1996. Cash
used for acquisitions decreased $36.1 million and cash proceeds from the sale of
discontinued operations decreased $23.8 million in 1997 compared to 1996. In
addition, cash used for capital expenditures increased $4.9 million and other
assets provided $8.6 million more in 1997. Net cash used in financing activities
was $51.7 million for the year ended December 31, 1997, an increase of $11.1
million over the use of $40.6 million for the year ended December 31, 1996. The
net repayment of long-term obligations was $28.1 million higher in 1997 than in
1996. This was partially offset by an increase in cash provided by the accounts
receivable securitization of $15.6 million and a decrease in cash used by
financing fees of $3.9 million in the year ended December 31, 1997 compared to
the same period of 1996.
 
     Capital Expenditures. The Company had $16.3 million of capital expenditures
related to continuing operations in 1997. The Company's existing credit
agreement contains restrictions on the Company's ability to make capital
expenditures. Based on present estimates, management believes that the amount of
capital
 
                                       29
<PAGE>   31
 
expenditures permitted to be made under the existing credit agreement will be
adequate to maintain the properties and businesses of the Company's continuing
operations.
 
     Liquidity. The Company's principal sources of liquidity are cash flow from
operations and borrowings under the New Credit Facility. The Company's principal
uses of cash will be debt service requirements, capital expenditures,
acquisitions and working capital. The Company expects that ongoing requirements
for debt service, capital expenditures and working capital will be funded from
operating cash flow and borrowings under the New Credit Facility. In connection
with future acquisitions, the Company may require additional funding which may
be provided in the form of additional debt, equity financing or a combination
thereof. There can be no assurance that any such additional financing will be
available to the Company on acceptable terms.
 
     The Company incurred substantial indebtedness in connection with the Merger
and the Merger Financing. On a pro forma basis, after giving effect to the
Merger, the Merger Financing and the application of the proceeds thereof, the
Company would have had approximately $682.0 million of indebtedness outstanding
as of March 31, 1998 as compared to $370.4 million of indebtedness outstanding
as of March 31, 1998 on a historical basis. In addition, on the same pro forma
basis, the Company would have a stockholders' deficit of $475.4 million at March
31, 1998 as compared to a stockholders' deficit of $156.8 million as of March
31, 1998 on a historical basis. The Company's significant debt service
obligations following the Merger could, under certain circumstances, have
material consequences to security holders of the Company. See "Risk Factors."
 
     In connection with the Merger, Mercury raised approximately $140 million
through the issuance of approximately 2,608,696 shares of its Common Stock,
2,000,000 shares of its Preferred Stock and warrants to purchase 353,428 shares
of its Common Stock at an exercise price of $0.01 per share, and approximately
$94.6 million aggregate gross proceeds of the Debentures. As a result of the
Merger, the proceeds from the sale of such securities became an asset of
Holdings, each share of Mercury Common Stock became a share of Holdings Common
Stock, each share of Mercury Preferred Stock became a share of Holdings
Preferred Stock, each DLJMB Warrant by its terms became exercisable for an equal
number of shares of Holdings Common Stock and Holdings succeeded to the
obligations of Mercury with respect to the Debentures. In addition, the Company
raised approximately $205.4 million through the issuance of the Senior
Subordinated Notes and $430 million through the New Credit Facility. In
addition, in connection with the Merger, certain members of senior management
purchased 143,192 shares of Holdings Common Stock for approximately $4.9 million
through the Management Share Purchase, of which approximately $3.6 million was
provided through the Management Loans.
 
     The term loan facility under the New Credit Facility consists of (i) a $100
million Term A loan, (ii) a $115 million Term B loan and (iii) a $115 million
Term C loan. The Term A loan will mature six years after the closing date, the
Term B loan will mature seven years after the closing date and the Term C loan
will mature eight years after the closing date. The New Credit Facility also
includes a $100 million revolving credit facility, which is subject to increase
by up to $25 million upon request by Thermadyne LLC and that will terminate six
years after the closing date.
 
     Borrowings under the New Credit Facility generally will bear interest based
on a margin over, at the Company's option, the base rate or LIBOR. The
applicable margin will vary based on the Thermadyne LLC's ratio of consolidated
indebtedness to adjusted EBITDA. Thermadyne LLC's obligations under the New
Credit Facility will be secured by substantially all of the assets of Thermadyne
LLC, including a pledge of the capital stock of all of its subsidiaries, subject
to certain limitations with respect to foreign subsidiaries. In addition,
Holdings has guaranteed the obligations of Thermadyne LLC under the New Credit
Facility. Such guarantee is only recourse to Holdings' pledge of all of the
outstanding capital stock of Thermadyne LLC to secure Thermadyne LLC's
obligations under the New Credit Facility. The New Credit Facility contains
customary covenants and events of default including substantial restrictions on
Thermadyne LLC's ability to make dividends or other distributions to Holdings.
 
     The Old Debentures were issued by Mercury, became obligations of Holdings
following the Merger and are not guaranteed by Thermadyne LLC or any of its
consolidated subsidiaries. The Debentures will mature in
 
                                       30
<PAGE>   32
 
2008 and will not require cash interest payments until 2003. The Debentures
contain customary covenants and events of default, including covenants that
limit the ability of the Company and its subsidiaries to incur debt, pay
dividends and make certain investments.
 
     The Senior Subordinated Notes were issued by Thermadyne LLC and Thermadyne
Capital and, were guaranteed by certain of the Company's domestic subsidiaries.
The Senior Subordinated Notes will mature in 2008. Interest on the Senior
Subordinated Notes will be payable semiannually in cash. The Senior Subordinated
Notes contain customary covenants and events of default, including covenants
that limit the ability of Thermadyne LLC and its subsidiaries to incur debt, pay
dividends and make certain investments.
 
     The Preferred Stock issued in connection with the Merger has an initial
liquidation preference of $50 million and will accrue dividends at an annual
rate of approximately 13%. Prior to the fifth anniversary of the original date
of issuance, such dividends will be paid through increases in the liquidation
preference thereof or through the issuance of additional shares of Preferred
Stock. The Company is required to redeem the Preferred Stock on May 15, 2010 at
a redemption price equal to the liquidation preference per share, plus accrued
and unpaid dividends, if any, to the date of redemption. In addition, in the
event of a "change of control," as defined in the certificate of designation
related thereto, holders of Preferred Stock will have the right to require the
Company to repurchase its shares at a purchase price equal to 101% of the
liquidation preference thereof plus accrued and unpaid dividends, if any.
 
     The Company anticipates that its operating cash flow, together with
borrowings under the New Credit Facility, will be sufficient to meet its
anticipated future operating expenses, capital expenditures and to service its
debt requirements as they become due. However, the Company's ability to make
scheduled payments of principal of, to pay interest on or to refinance its
indebtedness and to satisfy its other debt obligations will depend upon its
future operating performance, which will be affected by general economic,
financial, competitive, legislative, regulatory, business and other factors
beyond its control. See "Risk Factors."
 
EFFECT OF INFLATION; SEASONALITY
 
     Inflation has not been a material factor affecting the Company's business.
In recent years, the cost of electronic components has remained relatively
stable due to competitive pressures within the industry, which has enabled the
Company to contain its service costs. The Company's general operating expenses,
such as salaries, employee benefits, and facilities costs, are subject to normal
inflationary pressures.
 
     The operations of the Company are generally not subject to seasonal
fluctuations.
 
YEAR 2000 COMPLIANCE
 
     The year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of the Company's
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices, or
engage in similar normal business activities. The Company believes that its
internal systems are Year 2000 compliant or will be upgraded or replaced in
connection with previously planned changes to information systems prior to the
need to comply with Year 2000 requirements. However, the Company is uncertain as
to the extent its customers and vendors may be affected by Year 2000 issues that
require commitment of significant resources and may cause disruptions in the
customers' and vendors' businesses.

                                    BUSINESS
 
OVERVIEW
 
     Thermadyne is a leading global manufacturer of cutting and welding products
and accessories. The Company manufactures a broad range of gas (oxy-fuel) and
electric arc cutting and welding products that are ultimately sold to end-user
customers principally engaged in the aerospace, automotive, construction, metal
fabrication, mining, mill and foundry, petroleum and shipbuilding industries.
Thermadyne sells its products through a long-established domestic network of
approximately 1,100 independent distributors who market Thermadyne products to
over 10,000 end-user customers. For the twelve months ended March 31, 1998, the
Company's net sales and Adjusted EBITDA, on a pro forma basis, were $548.2
million and $115.5 million, respectively.
 
     The Company's core products enjoy leading brand recognition, a reputation
for quality and strong market positions. In 1994, following the Company's
comprehensive financial restructuring under chapter 11 of the United States
Bankruptcy Code (the "Restructuring"), current management initiated a series of
transactions to focus the Company's business exclusively on the cutting and
welding industry. As part of this strategy, the Company divested three non-core
businesses: the Clarke floor maintenance business (1996); the Coyne Cylinder
Company (1996); and the Deloro Stellite wear resistance business (1997). In
addition, the Company initiated an acquisition strategy, purchasing six cutting
and welding products businesses since the Restructuring, which businesses
collectively generated approximately $169 million in annual revenues at the
respective times of acquisition. The acquisitions of cutting and welding
businesses provided, and will continue to provide, an opportunity for Thermadyne
to expand distribution of existing product lines into new geographic regions and
to sell acquired product lines through Thermadyne's existing distribution
network. As a result of this repositioning strategy, along with ongoing new
product introductions, an extensive distribution network and market leading
brands, the Company has achieved a compound annual growth in net sales and
Adjusted EBITDA of 20.3% and 12.5%, respectively, from 1993 to 1997.
 
     According to the United States Department of Commerce, domestic welding
industry revenues totaled over $3.6 billion in 1997. The domestic industry has
grown at an annual rate of 5.9% since 1989 and is expected to grow 4.2% in 1998.
Global welding industry revenues are estimated to total over $10.0 billion and
management believes that growth in the international market has been faster than
the domestic market, driven, in large part, by infrastructure spending in
developing markets. International markets, including Australia and Italy,
represented approximately 42% of the Company's net sales in 1997, up from
approximately 20% of net sales in 1994. Although the industry has begun to
experience global consolidation, it continues to be very fragmented.

COMPETITIVE STRENGTHS
 
     Thermadyne possesses a number of competitive strengths that have allowed it
to develop and maintain a strong position within the cutting and welding
industry, including the following:
 
     Market Leading Brands. Management believes that the strength and longevity
of the numerous Thermadyne brand names create a significant competitive
advantage and position Thermadyne as one of the leaders in the cutting and
welding industry. Each of the Company's major divisions maintains
industry-leading brand names with significant market shares. Management believes
that VICTOR(R), founded in 1913, is the leading brand name in domestic
gas-operated cutting and welding torches and equipment; TWECO(R), founded in
1936, is the leading domestic manufacturer of MIG and manual welding torches;
ARCAIR(R) is the leading domestic brand name of TIG torch and accessory
products; THERMAL DYNAMICS(R), founded in 1957, is a leading domestic
manufacturer of manual plasma cutting products; and CIGWELD(R), founded in 1922,
is the leading brand name in the Australia/New Zealand cutting and welding
products market. Each of the manufacturing operations associated with these
brands is ISO-9000 series certified.
 
     Diverse and Stable Customer Base. The Company's customer base includes
cutting and welding product distributors as well as end-user customers
principally engaged in the aerospace, automotive, construction, metal
fabrication, mining, mill and foundry, petroleum and ship building industries.
No one customer accounted for more than 9% of the Company's 1997 net sales.
Further, the Company's top 20 customers have been associated with the Company
for an average of over 10 years.
 
     Established, Effective Distribution Channels. The Company believes that its
strong, established and long-standing relationships with over 1,100 independent
cutting and welding products distributors in the United States provide a
significant competitive advantage and support the Company's strong market
position. Thermadyne's domestic distributor relationships are maintained by 11
area business managers who oversee the Company's relationships with large
distributors and by separate product-specific sales forces for each of
Thermadyne's business units. Management believes that this unique structure,
which combines relationship managers with technically trained product
specialists, will enable the Company to more effectively maintain and utilize
its distributor networks. Management also believes that this established
distribution network enables the Company to achieve market penetration when
introducing newly developed or acquired products.
 
     Proven and Committed Senior Management Team. Thermadyne's management team
has repositioned the Company over the past four years to focus exclusively in
its core cutting and welding markets. This
 
                                       33
<PAGE>   35
 
repositioning was accomplished through divestitures of non-core assets and
acquisitions of strategic businesses or product lines. In addition, through
aggressive new product development and acquisition strategies, the management
team has positioned the Company to realize a 20.3% compound annual growth rate
in net sales from 1993 to 1997. In connection with the Merger each member of the
senior management team signed an employment contract with the Company.
Additionally, the Company adopted an incentive plan to tie each member of senior
management's compensation to the Company's financial performance. See "Executive
Compensation."
 
BUSINESS STRATEGY
 
     Thermadyne has developed a business strategy designed to enhance its strong
market positions and continue to improve its growth and profitability. The
primary elements of the Company's business strategy are as follows:
 
     Continue New Product Development and Enhancement. The foundation for
Thermadyne's strong market positions and leading brand names is the development
and introduction of new products and enhancements of existing products. The
Company believes it is at the forefront of cutting and welding technology with a
proven track-record of continual new product introductions and existing product
enhancements that have resulted in the issuance of more than 262 issued or
pending United States and foreign patents. New products and product enhancements
are designed to add value for customers, including enhanced safety features,
improved productivity and ergonomics and an improved welding environment.
Examples of recent new product introductions include robotic welding systems and
accessories, high-purity instrumentation, automated plasma cutting and safety
products as well as underwater cutting electrodes. During 1997, the Company
introduced over 135 new products or product enhancements, and the Company
expects to continue this effort in the future.
 
     Expand Strategic Acquisitions. The Company has completed six acquisitions
since 1993, which collectively generated approximately $169 million in annual
revenues at the respective times of acquisition, including over $135 million of
revenues in Australia and Italy. The Company believes that numerous acquisition
candidates exist globally, and the Company intends to continue to seek new
acquisition opportunities in its cutting and welding business. Thermadyne
intends to continue its focused acquisition strategy that includes the following
principal elements: (i) entering and expanding in geographic areas where the
Company does not currently have a significant presence through acquisitions of
local cutting and welding businesses and (ii) expanding in geographic areas
where the Company currently maintains a strong presence through the acquisition
of complementary product lines.
 
     Leverage Existing Distribution Network. The Company intends to leverage its
existing distribution network through the acquisition or introduction of new
products and product enhancements. Management believes that when the Company
acquires a local presence in a new geographic area, it can utilize the acquired
distribution network to sell existing Thermadyne brands into that local market.
In addition, the Company believes that significant opportunities exist to
purchase complementary product lines and expand its business by selling the new
product lines through Thermadyne's extensive distribution network. For example,
through recent acquisitions the Company has expanded its offering of filler
metals, conventional arc welding power supplies, safety equipment and
engine-driven welding power sources and began marketing such products through
its established distribution network. The Company intends to continue this
strategy of penetrating new welding product markets by leveraging its extensive
distribution network in conjunction with its new product development and focused
acquisition strategies.
 
     Broaden International Presence. Thermadyne has maintained an international
presence for over 30 years and continues to broaden its presence throughout the
world. International sales accounted for approximately 42% of net sales in 1997
as compared to approximately 20% in 1994. The Company has established a
dedicated international market presence and maintains the leading position in
Australia/New Zealand and significant and growing positions in Europe, Asia and
Latin America. Management intends to continue the expansion of its strong
domestic brand names into the international market and to continue to penetrate
the growing Asian and Latin American cutting and welding markets.
 
                                       34
<PAGE>   36
 
     Continue Cost Reduction Efforts. Thermadyne strives to continually improve
manufacturing efficiencies and reduce unit costs. In December 1997, the Company
implemented a cost reduction program that includes the following principal
elements: (i) vendor rationalization and consolidation; (ii) manufacturing
process and productivity improvements and product design changes; (iii)
personnel rationalization and expense reductions; (iv) advertising and trade
show expense reductions; (v) aircraft, charter and other travel expense
reductions; and (vi) elimination of annual sales meeting. In addition, the
Company has initiated the implementation of a new global information system that
is designed to allow the Company to further integrate administrative functions
and improve information flow across business unit lines.
 
     Continue Dedicated Customer Service. The Company believes that effective
and proactive customer service has enabled the Company to build and maintain its
leading market positions and strong distributor relationships. Management plans
to continue this strategy of enhancing distributor and end-user relationships
through continuous customer service improvements. Each of Thermadyne's divisions
maintains a dedicated, well trained, technically oriented and product-specific
sales and customer service team. Management believes that the dedicated product
teams provide Thermadyne with a significant competitive advantage. In addition,
to further improve customer service, the Company has implemented a national
accounts team of 11 area business managers to support the dedicated product
sales and service teams and further support sales to the Company's key
distributors.
 
PRINCIPAL PRODUCTS
 
     The Company manufactures a broad range of both gas (oxy-fuel) and arc
cutting and welding equipment (including a line of advanced plasma arc cutting
systems and oxy-fuel apparatus), accessories and consumables, including repair
parts. Over 40% of the Company's 1997 net sales were derived from the sale of
consumables and repair parts. Gas cutting and welding torches burn a mixture of
oxygen and fuel gas, typically acetylene. Arc cutting and welding systems are
powered by electricity. The major arc cutting and welding systems are plasma,
stick, MIG and TIG. Arc technology is more sophisticated than gas technology and
can be used on more types of metals. In addition, arc equipment produces less
distortion in the surrounding metal and it cuts and welds faster, reducing labor
costs. However, gas technology is more portable and generally less expensive
than arc technology and therefore remains important in many industries.
 
     The Company conducts its operations through the following subsidiaries:
 
     Thermal Dynamics -- Plasma Arc Cutting Products. Thermal Dynamics
Corporation ("Thermal Dynamics"), located in West Lebanon, New Hampshire and
founded in 1957, developed many of the early plasma cutting systems and
maintains its position as a leading manufacturer of plasma cutting systems and
replacement parts. Thermal Dynamics' product line ranges from a portable 20 amp
unit to large 1000 amp units. Thermal Dynamics' end-users are engaged primarily
in fabrication and repair of sheet metal and plate products found in fabricated
structural steel and non-ferrous metals, automotive products, appliances, sheet
metal, HVAC, general fabrication, shipbuilding and general maintenance.
 
     Advantages of the plasma cutting process over other methods include faster
cutting speeds, the ability to cut ferrous and non-ferrous alloys and minimum
heat distortion on the material being cut. Plasma cutting also permits metal
cutting using only compressed air and electricity.
 
     Tweco -- Electric Arc Products and Arc Gouging Systems. Tweco Products,
Inc. ("Tweco"), located in Wichita, Kansas and founded in 1936, manufactures a
line of arc welding replacement parts and accessories, including electrode
holders, ground clamps, cable connectors, terminal connectors and lugs and cable
splicers, and a variety of automatic and semi-automatic welding guns and cable
assemblies utilized in the arc welding process. Tweco also manufactures manual
stick electrode holders, ground clamps and accessories. Manual stick welding is
one of the oldest forms of welding and is used primarily by smaller welding
shops which perform general repair, maintenance and fabrication work. Tweco's
end-users are primarily engaged in the manufacture or repair and maintenance of
transportation equipment, including automobiles, trucks, aircraft, trains and
ships; the manufacture of a broad range of machinery; and the production of
fabricated metal products, including structural metal, hand tools and general
hardware.
 
                                       35
<PAGE>   37
 
     Tweco is a leading domestic manufacturer of MIG welding guns. The MIG
process is an arc welding process utilized in the fabrication of steel,
aluminum, stainless steel and other metal products and structures. In the MIG
process, a small diameter consumable electrode wire is continuously fed into the
arc. The welding arc area is protected from the atmosphere by a "shielding" gas.
The welding guns and cable assemblies manufactured by Tweco carry the continuous
wire electrode, welding current and shielding gas to the welding arc. Tweco
manufactures a related line of robotic welding accessory products. This new
accessory line includes, but is not limited to, a robotic torch with patented
consumables, a robotic deflection mount, a robotic cleaning station, robotic
arms and an anti-splatter misting system.
 
     Through its Arcair product line, Tweco manufactures equipment and related
consumable materials for "gouging," a technique that liquefies metal in a narrow
groove and then removes it using compressed air. Gouging products are often used
in joint preparation prior to a welding process. Numerous other applications
exist for these gouging systems, such as removal of defective welds, removal of
trim in foundries and repair of track, switches and freight cars in the railroad
industry. Arcair also manufactures a line of underwater welding and gouging
equipment.
 
     In addition to gouging products, Arcair produces a patented exothermic
cutting system, SLICE(R). This system generates temperatures in excess of 70008F
and can quickly cut through steel, concrete and other materials. SLICE(R) has
many applications, including opening clogged steel furnaces and providing rapid
entry in fire and rescue operations. Arcair has developed an underwater version
of the SLICE(R)cutting system for use in the marine repair and salvage industry.
 
     Arcair also manufactures TIG torches and accessories. The TIG process can
be used to fuse metals of almost all alloys and in thicknesses down to foil
size. TIG welding is used for pressure vessels, such as tanks, valves and pipes
and is relied on heavily in welding nuclear components. Fabrications involving
aluminum, magnesium and other specialty metals for use in aircraft, ships and
weapon systems also utilize the TIG process.
 
     Arcair provides a complete line of chemicals used in the welding industry.
Chemicals are used for weld cleaning and as agents to reduce splatter adherence
on the metal being welded. Chemicals are also used to reduce splatter adherence
in welding nozzles in MIG applications.
 
     Victor -- Oxy-Fuel Gas Products. Victor Equipment Company ("Victor") has
plants in Abilene and Denton, Texas and Gallman, Mississippi and was founded in
1913. Victor is a leading domestic manufacturer of gas operated cutting and
welding torches and gas and flow pressure regulation equipment. Victor's torches
are used to cut ferrous metals and to weld, heat, solder and braze a variety of
metals, and its regulation equipment is used to control pressure and flow of
most industrial and specialty gases. In addition, Victor manufactures a variety
of replacement parts, including welding nozzles and cutting tips of various
types and sizes and a line of specialty gas regulators purchased by end-users in
the process control, electronics and other industries. Victor also manufactures
a wide range of medical regulation equipment serving the oxygen therapy market,
including home health care and hospitals.
 
     The torches produced by Victor are commonly referred to as oxy-fuel
torches. These torches combine a mixture of oxygen and a fuel gas, typically
acetylene, to produce a high temperature flame. These torches are designed for
maximum durability, repair ability and performance utilizing patented built-in
reverse flow check valves and flash arresters in several models. Victor also
manufactures lighter-duty hand-held heating, soldering and brazing torches.
Pressure regulators, which are basically diaphragm valves, serve a broad range
of industrial and specialty gas process control operations.
 
     The principal uses of the Victor torch are cutting steel in metal
fabricating applications such as shipbuilding, construction of oil refineries,
power plants and manufacturing facilities, and welding, heating, brazing and
cutting in connection with maintenance of machinery, equipment and facilities.
Victor sells its lighter-duty products to end-user customers principally engaged
in the plumbing, refrigeration and heating, ventilation and air conditioning
industries. The relative low cost, mobility and ease of use of Victor torches
makes them suitable for a wide variety of uses.

cantilever type used in general fabrication and job shops to the large precision
gantry type found in steel service centers and specialty cutting applications.
These metal cutting tables can be used in virtually any metal fabrication plant.
 
     Stoody -- Hardfacing Products. Stoody Company ("Stoody"), located in
Bowling Green, Kentucky and with operations founded in 1921, is a recognized
world leader in the development and manufacture of hardfacing welding wires,
electrodes and rods. While Stoody's primary product line is iron-based welding
 
                                       37
<PAGE>   39
 
wires, Stoody also participates in the markets for cobalt-based and nickel-based
electrodes, rods and wires, which are essentially protective overlays, deposited
on softer base materials by various welding processes. This procedure, referred
to as "hardfacing" or "surface treatment," adds a more resistant surface,
thereby increasing the component's useful life. Lower initial costs, the ability
to treat large parts, and ease and speed of repairs in the field are some of the
advantages of hardfacing over solid wear resistant components. A variety of
products have been developed for hardfacing applications in industries utilizing
earth moving equipment, agricultural tools, crushing components, and steel mill
rolls, and in virtually all applications where metal is exposed to external wear
factors.
 
     Thermal Arc -- Arc Welders, Plasma Welders and Wire Feeders. In 1997, the
inverter and plasma arc welder business of Thermal Dynamics and Arcsys were
combined to form Thermal Arc, Inc. ("Thermal Arc"). The combined operation is
located in Troy, Ohio and produces a full line of inverter and transformer-
based electric arc welders, plasma welders, engine driven welders and wire
feeders. Thermal Arc products compete in the marketplace for construction,
industrial and automated applications, and serve a large and diverse user base.
 
     The inverter arc welding power machines use high frequency power
transistors to provide welding machines that are extremely portable and power
efficient when compared to conventional welding power sources. Plasma welding
dramatically improves productivity for the end-user. Additionally, conventional
transformer-based machines provide a cost-effective alternative for markets
where low cost and simplicity of maintenance are a high priority.
 
     GenSet -- Engine-Driven Welders and Generators. GenSet, located in Pavia,
Italy, commenced operations in 1976 with the production of small generating

INTERNATIONAL BUSINESS
 
     The Company had aggregate international sales from continuing operations of
approximately $220.2 million, $171.6 million and $67.5 million for the fiscal
years ended December 31, 1997, 1996 and 1995, respectively, or approximately
42%, 39% and 21%, respectively, of net sales in each such period. The Company's
international sales are influenced by fluctuations in exchange rates of foreign
currencies, foreign economic conditions and other risks associated with foreign
trade. The Company's international sales consist of: (a) export sales of
Thermadyne products manufactured at domestic manufacturing facilities and, to a
limited extent, products manufactured by third parties, sold through overseas
field representatives of Thermadyne International Corporation ("Thermadyne
International"), a subsidiary of Thermadyne; and (b) sales of Thermadyne
products manufactured at international manufacturing facilities, sold by
Thermadyne's foreign subsidiaries. For further information concerning the
international operations of the Company, see the notes to the Consolidated
Financial Statements of the Company included elsewhere herein.
 
     Thermadyne International was formed in 1980 to coordinate Thermadyne's
efforts to increase international sales and sells cutting and welding products
through independent distributors in more than 80 countries.
 
                                       38
<PAGE>   40
 
In support of this effort, the Company operates distribution centers in Canada,
Australia, Italy, Mexico, Japan, Singapore, Brazil, the Philippines, Indonesia
and the United Kingdom and employs sales people located in 23 additional
countries.
 
DISTRIBUTION
 
     The Company's cutting and welding products are distributed through a
domestic network of approximately 1,100 independent welding products
distributors with over 2,800 locations who carry one or more of its product
lines. Relationships with the distributors are maintained by a separate sales
force for each of the Company's principal product lines. In addition, a team of
11 area business managers exists to support the sale of all of the Company's
product lines to its key distributors. The Company's products are distributed
internationally through a direct sales force and independent distributors.
 
RESEARCH AND DEVELOPMENT
 
     The Company has research and development groups for each of its product
lines that primarily conduct process and product development to meet market
needs. As of December 31, 1997, the Company employed approximately 125 persons
in its research and development groups, most of which are engineers.
 
PATENTS, LICENSES AND TRADEMARKS
 
     The Company's products are sold under a variety of trademarks and trade
names. The Company owns trademark registrations or has filed trademark
applications for all trademarks and has registered all trade names that the
Company believes are material to the operation of its businesses. The Company
also owns various patents and from time to time acquires licenses from owners of
patents to apply such patents to its operations. As of December 31, 1997, the
Company had 740 registered and pending trademarks and 262 registered and pending
patents. The Company does not believe any single patent or license is material
to the operation of its businesses taken as a whole.
 
COMPETITION
 
     The Company competes principally with a number of domestic manufacturers of
cutting and welding products, the majority of which compete only in limited
segments of the overall market. Management believes that competition is based
primarily on product quality, brand name, breadth and depth of product lines,
effectiveness of distribution channels, acumen of sales force, price and quality
of customer service. To date, the Company has experienced little direct foreign
competition in its U.S. markets due to the relatively limited size of such
markets, the inability of foreign manufacturers to establish effective
distribution channels and the relatively non-labor intensive nature of the
cutting and welding product manufacturing process. The Company also competes in
certain international markets in which it faces substantial competition from
foreign manufacturers of cutting and welding products.
 
RAW MATERIALS
 
     The Company has not experienced any difficulties in obtaining raw materials
for its operations because its principal raw materials, copper, brass, steel and
plastic, are widely available and need not be specially manufactured for use by
the Company. Certain of the raw materials used in hardfacing products, such as
cobalt and chromium, are available primarily from sources outside the United
States, some of which are located in countries that may be subject to economic
and political conditions which could affect pricing and disrupt supply. Although
the Company has historically been able to obtain adequate supplies of these
materials at acceptable prices and has been able to recover the costs of any
increases in the price of raw materials in the form of higher unit sales prices,
restrictions in supply or significant fluctuations in the prices of cobalt,
chromium and other raw materials could adversely affect the Company's business.
 
     The Company also purchases certain products which it either uses in its
manufacturing processes or resells. These products include, but are not limited
to, electronic components, circuit boards, semi-conductors,
 
                                       39
<PAGE>   41
 
motors, engines, pressure gauges, springs, switches, lenses and chemicals. The
Company believes its sources of such products are adequate to meet foreseeable
demand.
 
EMPLOYEES
 
     As of December 31, 1997, the Company employed 3,563 people, of which
approximately 637 were engaged in sales and marketing activities, 225 were
engaged in administrative activities, 2,584 were engaged in manufacturing
activities and 117 were engaged in engineering activities. Labor unions
represent none of the Company's work force in the United States and virtually
all of the manufacturing employees in its foreign operations. The Company
believes that its employee relations are good. The Company has not experienced
any significant work stoppages.
 
FACILITIES
 
     The Company operates 12 manufacturing facilities in the United States,
Italy, the Philippines and Australia. All domestic manufacturing facilities,
leases and leasehold interests are encumbered by liens securing the Company's
obligations under the New Credit Facility. The Company considers its plants and
equipment to be modern and well-maintained and believes its plants have
sufficient capacity to meet future anticipated expansion needs.
 
     The Company leases and maintains a 43,600 square foot facility located in
St. Louis, Missouri, which houses the executive offices of the Company and its
operating subsidiaries, as well as all centralized services.

     In addition, the Company has subleased 264,000 square feet of its 325,000
square foot facility in City of Industry, California, which formerly was the

LEGAL PROCEEDINGS AND ENVIRONMENTAL MATTERS
 
     The Company is a party to ordinary litigation incidental to its businesses,
including a number of product liability cases seeking substantial damages. The
Company maintains insurance against any product liability claims. Coverage for
most years has a $500,000 self insured retention with $500,000 of primary
insurance per claim. In addition, the Company maintains umbrella policies
providing an aggregate of $50,000,000 in coverage for product liability claims.
Although it is difficult to predict the outcome of litigation with any
certainty, the Company believes that the liabilities which might reasonably
result from such lawsuits, to the extent not covered by insurance, will not have
a material adverse effect on the Company's financial condition or results of
operations.
 
     The Company's operations are subject to federal, state, local and foreign
laws and regulations relating to the storage, handling, generation, treatment,
emission, release, discharge and disposal of certain substances and wastes. The
Company is currently not aware of any citations or claims filed against it by
any local, state, federal and foreign governmental agencies which, if
successful, would have a material adverse effect on the Company's financial
condition or results of operations.
 
     The Company may be required to incur costs relating to remediation of
properties, including properties at which the Company disposes of waste, and
environmental conditions could lead to claims for personal injury, property
damage or damages to natural resources. The Company is aware of environmental
conditions at certain properties which it now or previously owned or leased
which are undergoing remediation. The Company does not believe that the cost of
such remediation will have a material adverse effect on the Company's business,
financial condition or results of operations.
 
     Certain environmental laws, including but not limited to, the Comprehensive
Environmental Response, Compensation and Liability Act ("CERCLA" or "Superfund")
and the equivalent state Superfund laws, provide for strict, joint and several
liability for investigation and remediation of spills or other releases of
hazardous substances. Such laws may apply to conditions at properties presently
or formerly owned or operated by the Company or by its predecessors or
previously owned business entities, as well as to conditions at properties at
which wastes or other contamination attributable to the Company or its
predecessors or previously owned business entities come to be located. The
Company has in the past and may in the future be named a PRP at off-site
disposal sites to which it has sent waste. The Company does not believe that the
ultimate cost relating to Superfund sites will have a material adverse effect on
the Company's financial condition or results of operations. See "Risk
Factors -- Environmental Matters."

                        THE MERGER AND MERGER FINANCING
 
THE MERGER FINANCING
 
     The funding required to pay the cash portion of the Merger Consideration,
the Option Cash Proceeds and the ESPP Cash Proceeds, to refinance and/or retire
outstanding indebtedness of the Company, and to pay expenses incurred in
connection with the Merger was approximately $808 million. These cash
requirements were funded with the proceeds obtained from concurrent equity and
debt financings, Thermadyne LLC and Thermadyne Capital issued the Senior
Subordinated Notes and Thermadyne LLC entered into a syndicated senior secured
loan facility providing for term loan borrowings in the aggregate principal
amount of approximately $330 million and revolving loan borrowings of $100
million (subject to a potential, but uncommitted, increase of up to $25 million
upon the request of Thermadyne LLC). In connection with the Merger, Thermadyne
LLC borrowed all term loans available under the New Credit Facility plus
approximately $25 million of revolving loans. The remaining revolving loans will
be available to fund the working capital requirements of the Company. The
proceeds of such financings were distributed to Holdings in the form of a
dividend. See "Description of New Credit Facility" and "Certain Relationships
and Related Transactions."
 
     Mercury issued approximately $94.6 million aggregate proceeds of the
Debentures. In connection with the Merger, Holdings succeeded to the obligations
of Mercury with respect to the Debentures. The DLJMB Funds also purchased
2,608,696 shares of Mercury Common Stock, 2,000,000 shares of Mercury Preferred
Stock and the DLJMB Warrants for approximately $140 million. As a result of the
Merger, the proceeds of such purchases became an asset of Holdings, each share
of Mercury Common Stock became a share of Holdings Common Stock, each share of
Mercury Preferred Stock became a share of Holdings Preferred Stock and each
DLJMB Warrant to acquire Mercury Common Stock became exercisable for an equal
number of shares of Holdings Common Stock. In addition, in connection with the
Merger, certain members of senior management purchased 143,192 shares of
Holdings Common Stock for approximately $4.9 million through the Management
Share Purchase, of which approximately $3.6 million was provided through the
Management Loans.
 
THE MERGER
 
     As a result of the Merger, each share of Holdings Common Stock held by
Holdings as treasury stock or owned by Mercury immediately prior to the
effectiveness of the Merger was cancelled, and no payment was made with respect
thereto; each share of Mercury Common Stock outstanding immediately prior to the
effectiveness of the Merger was converted into and became one share of Holdings
Common Stock with the same rights, powers and privileges as the shares so
converted; each share of Mercury Preferred Stock, outstanding immediately prior
to the effectiveness of the Merger was converted into and became one share of
preferred stock of Holdings with the same rights, powers and privileges as the
shares of preferred stock so converted; each outstanding DLJMB Warrant to
purchase Mercury Common Stock became exercisable for an equal number of shares
of Holdings Common Stock on the same terms and conditions as the DLJMB Warrant;
and each share of Holdings Common Stock outstanding immediately prior to the
effectiveness of the Merger was converted into the following (the "Merger
Consideration"): for each such share with respect to which an election to retain
Holdings Common Stock was effectively made and not revoked ("Stock Electing
Shares"), the right to retain approximately one share of Holdings Common Stock,
and for each such share (other than Stock Electing Shares), the right to receive
in cash from Mercury an amount equal to $34.50 (the "Cash Merger
Consideration"). Because the Merger required approximately 4.3% (or 485,010) of
the outstanding shares of Holdings Common Stock prior to the Merger to be
retained by existing stockholders of Holdings, the right to receive the Merger
Consideration was subject to proration. As a result of proration, each Stock
Electing Share was converted into .076 of a share of Holdings Common Stock and
the right to receive $34.50 in cash in lieu of shares not converted into
Holdings Common Stock. As a result of the Merger 10,690,283 shares of Holdings
Common Stock (approximately 95.7% of the presently issued and outstanding
shares) were converted into cash, as described above, and approximately 4.3% (or
485,010) of such shares were retained by existing stockholders. As a result of
the Merger, the shares of Mercury Common Stock were
 
                                       42
<PAGE>   44
 
converted into Holdings Common Stock representing approximately 80.6% of
Holdings Common Stock (or 75.7% on a fully diluted basis) after the Merger.
 
     As a result of the Merger, the DLJMB Warrants permit the holders thereof to
purchase an additional 353,428 shares of Holdings Common Stock.
 
     As a result of the Merger, each outstanding option to acquire shares of
Holding Common Stock granted to employees and directors, (excluding shares
subject to purchase under the Holding's Employee Stock Purchase Plan (the
"ESPP")), whether vested or not (the "Options"), were canceled. In lieu thereof,
the holders of such Options received, with respect to each Option, a cash
payment in an amount equal to the product of (x) the excess, if any, of $34.50
over the exercise price of such Option and (y) the number of shares of Holding
Common Stock subject to such Option (the "Option Cash Proceeds").
 
     In addition, upon effectiveness of the Merger, rights to purchase shares of
Holding Common Stock under the ESPP were canceled. In lieu thereof, participants
in the ESPP received a cash payment in the amount equal to the product of the
number of shares of Holding Common Stock subject to purchase by such
participants thereunder and $34.50 (the "ESPP Cash Proceeds").

(1) The options to purchase Holdings Common Stock were granted under Holdings'
    1993 Management Option Plan or the Holdings' 1996 Employee Stock Option Plan
    and become exercisable in five equal annual installments commencing on the
    first anniversary of the date of grant. All options become exercisable upon
    a change of control (as defined). In addition, such options continue to vest
    after any termination of employment for so long as the optionee is entitled
    to receive severance benefits under any employment arrangement with
    Holdings. Replacement options may be granted, in the Compensation
    Committee's sole discretion, if a named executive officer exercises such
    options using previously owned shares of Holdings Common Stock.
 
(2) The grant date present value of each option grant was determined using a
    variation of the Black-Scholes option pricing model. The estimated values
    presented are based on the following assumptions made as of the time of
    grant: an expected dividend yield of 0%; an expected option term of 10
    years; volatility of .339 (based on historical stock price observations just
    prior to each grant); and a risk-free rate of 6.72%. The actual value, if
    any, that an executive officer may realize from the exercise of the options
    will be the excess of the fair market value of Holdings Common Stock on the
    date of exercise over the exercise price. See "-- Fiscal Year-End Option
    Values."
 
     The following table provides information related to the number and value of
options held by the named executive officers at the end of 1997. On December 31,
1997, the closing sale price of Holdings Common Stock on NASDAQ was $29 1/2. No
named executive officer exercised any options during 1997.

     As a result of the Merger, all outstanding Options, whether or not vested,

exercise price of such Option multiplied by (y) the number of shares of Holdings
Common Stock subject to such Option.

EMPLOYMENT ARRANGEMENTS
 
     Employment Contracts. In connection with the Merger Holdings entered into
employment agreements with, among others, the following executive officers:
Randall E. Curran, James H. Tate, Stephanie N. Josephson, Robert D. Maddox and
Thomas C. Drury. The employment agreements terminate on May 22, 2001; however,
such agreements automatically renew on each May 22 for an additional period so
that a new three-year term begins upon each extension (unless the agreements are
earlier terminated as provided herein). Each such employee serves in their
current executive capacities with Holdings as a requirement of their respective
employment agreements.
 
     Messrs. Curran, Tate, Maddox and Drury and Ms. Josephson are entitled to
base salaries (subject to increase at the Board of Directors' discretion) of
$538,400, $290,175, $145,000, $145,000 and $175,000, respectively. In addition,
each employee is entitled to participate in an annual bonus plan providing for
an annual bonus opportunity. Pursuant to such bonus plan, Mr. Curran is entitled
to an annual bonus opportunity of not less than 100% of his base salary, Mr.
Tate is entitled to an annual bonus opportunity of not less than 75% of his base
salary and Ms. Josephson and Messrs. Maddox and Drury are each entitled to an
annual bonus opportunity of not less than 55% of his or her base salary. Each
such executive also is entitled to such benefits as are customarily provided to
the executives of Holdings and its subsidiaries. Each such executive is required
to devote all of his or her business time and attention to the business Holdings
and its subsidiaries.
 
     Each employment agreement provides that upon termination without cause or
constructive termination of such executive's employment (which includes, among
other things, reductions of compensation, title, position or duties), such
executive will be entitled to receive such executive's then current salary and
other benefits through the later to occur of the termination date of the
agreement or 18 months from the date of termination of such executive's
employment.
 
  Management Plans.
 
     Management Incentive Plan. In connection with the Merger, Holdings adopted
the Thermadyne Holdings Corporation Management Incentive Plan (the "Incentive
Plan"), which provides for the granting of up to 500,000 shares of Holdings
Common Stock to certain officers and employees of the Company. In connection
with the Merger options to purchase approximately 322,966 shares of Holdings
Common Stock were granted to certain officers and employees of the Company at an
exercise price of $34.50. Pursuant to the terms of the Incentive Plan, options
granted to certain members of senior management provide for both a "Time Vesting
Option" and a "Cliff Vesting Option." Under the Time Vesting Option, the option
vests and is exercisable with respect to twenty percent of the shares subject to
the Option on the day it was granted. Then, on each of the first five
anniversaries from that date the Option was granted, an additional sixteen
percent of the shares subject to the Option vests and becomes exercisable as
long as the Option recipient is still employed by Holdings or its subsidiary.
The Cliff Vesting Option becomes vested and exercisable with respect to twenty
percent of the shares on the thirteenth day after the availability of the
audited financial statements for each of the fiscal years ended December 31,
1998 through December 31, 2003, provided that the Option recipient is still
employed by Holdings or its subsidiary, and further provided, that the targeted
implied common equity value of Holdings was met for each such fiscal year. If
the targeted implied common equity value of Holdings is not attained for any of
the fiscal years ending on or before December 31, 2002, the Option will be
treated as vested and exercisable if the target is attained for the subsequent
year as long as the Option recipient is still employed by Holdings or its
subsidiary. If, after eight years from receipt of the Cliff Vesting Option, all
shares subject to such Option have not vested, such shares shall become fully
vested and exercisable, as long as, the Option is still employed by Holdings or
its Subsidiary.
 
     Direct Investment Program. In connection with the Merger, Holdings adopted
the Thermadyne Holdings Corporation Direct Investment Program (the "Investment
Program"), which provides for the purchase by certain members of management of
143,192 shares of Holdings Common Stock, of which 71,596 shares have been
designated as "Reinvestment Shares" and 71,596 shares have been designated as
"Coinvestment Shares." In connection with the Merger, Holdings issued all shares
available for issuance under the Investment Program. Of the Coinvestment Shares,
20% vest on each of the first five anniversaries of
 
                                       48
<PAGE>   50
 
the date of purchase, so long as the participant is employed by the Company as
of such anniversary. Additionally, upon the occurrence of a Change of Control
(as defined therein), all unvested Coinvestment Shares held by a participant
that is employed by the Company at such time shall vest. All Reinvestment Shares
became immediately vested at the time of purchase. A portion of the funds
required to purchase the shares under the Investment Program were provided
through the proceeds of loans made by the Company to participants in the
Investment Program. In the event of a participant's termination for Cause (as
defined therein), the Company has the right to purchase shares of such
participant purchased under the Investment Program at a price equal to (i) the
lesser of (A) $34.50 or (B) the fair market value of such shares on the date of
purchase by the Company, with respect to Coinvestment Shares (whether or not
vested), and (ii) the fair market value of such shares on the date of purchase
by the Company, with respect to Reinvestment Shares. In the event of a
participant's termination for other than Cause or the participant's death, the
Company has the right to purchase shares of such participant purchased under the
Investment Program at a price equal to (i) the lesser of (A) the sum of $34.50
and the Allocable Interest (as defined therein) or (B) the fair market value of
such shares on the date of purchase by the Company, with respect to unvested
Coinvestment Shares, and (ii) the fair market value of such shares on the date
of purchase by the Company, with respect to Reinvestment Shares.
 
COMPENSATION OF DIRECTORS
 
     Other than Messrs. Curran and Tate, each director of Holdings receives a
$12,000 annual retainer plus a $1,000 fee for each regular meeting of the Board
of Directors attended and a $500 fee for each meeting of a board committee
attended (other than meetings of the Executive Committee, for which members of
the committee other than Charles F. Moran, will receive a fee of $750). In
addition to those fees, Mr. Moran, as the Chairman of the Executive Committee,
received aggregate compensation of $60,000 for services he provided during the
twelve-month period ending February 28, 1997. For the period ending February 28,
1998, Mr. Moran is expected to receive aggregate compensation of $60,000 for
services to be provided by him in his capacity as Chairman of the Executive
Committee during such period. Directors also are reimbursed for all reasonable
travel and other expenses of attending meetings of the Board of Directors or
committees of the Board of Directors.
 
     On November 1, 1997, the Board of Directors granted options to purchase
1,000 shares of Holdings Common Stock to each of Messrs. Byrom, Druker, Berger
and Moran pursuant to Holdings' Non-Employee Directors Stock Option Plan.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     DLJ Capital Funding received customary fees and reimbursement of expenses
in connection with the arrangement and syndication of the New Credit Facility
and as a lender thereunder. DLJSC also received customary fees in connection
with the distribution of the Senior Subordinated Notes and the Old Debentures,
and the offer to purchase and consent solicitation for the Company's outstanding
Senior Notes and Subordinated Notes. Additionally, DLJ Bridge Finance, Inc.
received customary fees in connection with its commitment to provide bridge
financing in the event that the issuance of the Senior Subordinated Notes and
the Old Debentures did not occur. The aggregate fees to be received by these DLJ
entities for these services were approximately $20 million.
 
     Pursuant to a letter agreement dated January 16, 1998 (the "Engagement
Letter"), DLJMB engaged DLJSC to act as DLJMB's exclusive financial advisor with
respect to the Merger and, following the Merger, to act as the Company's
exclusive financial advisor for a period of five years (the "Engagement Period")
with respect to the review and analysis of financial and structural alternatives
available to the Company. Upon the consummation of the Merger, DLJMB's
obligations under the Engagement Letter were assumed by the Company.
 
     As compensation for the services to be provided by DLJSC under the
Engagement Letter, DLJSC received a fee of $4,000,000 upon the consummation of
the Merger and will be entitled to receive an annual advisory fee of $300,000,
payable quarterly in equal installments of $75,000. DLJSC will also be entitled
to reimbursement for all of its out-of-pocket expenses incurred in connection
with its engagement.
 
     During the Engagement Period, DLJSC is also entitled to act as the
Company's exclusive financial advisor, sole placement agent, sole initial
purchaser, sole managing underwriter or sole dealer-manager, as the case may be,
with respect to any Transaction (as hereinafter defined) the Company determines
to pursue. The term "Transaction" includes the following: (i) the sale, merger,
consolidation or any other business combination, in one or a series of
transactions, involving any portion of the business, securities or assets of the
Company; (ii) the acquisition (and any related matters such as financings,
divestitures, etc.) in one or a series of transactions, of all or a portion of
the business, securities or assets of another entity or person; (iii) any
recapitalization, refinancing, repurchase or restructuring of the Company's
equity or debt securities or indebtedness or any amendments or modifications to
the Company's debt securities or indentures whether or not in connection
therewith, involving, by or on behalf of the Company, an offer to purchase or
exchange for cash, property, securities, indebtedness or other consideration, or
a solicitation of consents, waivers of authorizations with respect thereto; (iv)
any spin-off, split-off or other extraordinary dividend of cash, securities or
other assets to stockholders of the Company; or (v) any sale of securities of
the Company effected pursuant to a private sale or an underwritten public
offering.
 
     The Company has agreed to indemnify and hold harmless DLJSC and its
affiliates, and the respective directors, officers, agents and employees of
DLJSC and its affiliates (each, an "Indemnified Person") from and against any
losses, claims, damages, judgments, assessments, costs and other liabilities and
will reimburse such Indemnified Persons for all fees and expenses (including the
reasonable fees and expenses of counsel) as they are incurred in investigating,
preparing, pursuing or defending any claim, action, proceeding or investigation
arising out of or in connection with advice or services rendered or to be
rendered by an Indemnified person pursuant to the Engagement Letter, the
transactions contemplated by the Engagement Letter or any Indemnified Person's
action or inactions in connection with any such advice, services or
transactions, other than liabilities or expenses that are determined by a
judgment of a court of competent jurisdiction to have resulted solely from such
Indemnified Person's gross negligence or willful misconduct.
 
     The Engagement Letter makes available the resources of DLJSC concerning a
variety of financial and operational matters. The services that have been and
will continue to be provided by DLJSC could not otherwise be obtained by the
Company without the addition of personnel or the engagement of outside
professional advisors. In the opinion of management, the fees provided for under
the Engagement Letter reasonably reflect the benefits received and to be
received by the Company.

     In connection with the Merger, a portion of the funds required to purchase
the shares under the Investment Program were provided through the proceeds of
loans made by the Company to participants in the Investment Program (the
"Management Loans"). Messrs. Curran, Tate, Maddox and Drury and Ms. Josephson
received secured, non-recourse loans from the Company in the amount of
$1,249,890, $367,606, $237,630, $223,222 and $288,413, respectively. The loans
bear interest at the rate of 5.69% per annum and are due in full on May 22,
2006. Upon the termination of a participant's termination of employment with the
Company other than the participant's death any outstanding loan will become due
and payable.
 
                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT
 
     The Old Debentures were sold by the Issuer on May 22, 1998, in the
Offering. In connection with that placement, the Issuer entered into the
Registration Rights Agreement, which requires that the Company file the
Registration Statement under the Securities Act with respect to the New
Debentures and, upon the effectiveness of the Registration Statement, offer to
the holders of the Old Debentures the opportunity to exchange their Old
Debentures for a like principal amount of New Debentures, which will be issued
without a restrictive legend and which generally may be reoffered and resold by
the holder without registration under the Securities Act. The Registration
Rights Agreement further provides that the Company must use its best efforts to
(i) cause the Registration Statement with respect to the Exchange Offer to be
declared effective on or before November 30, 1998 and (ii) consummate the
Exchange Offer on or before December 30, 1998. Except as provided below, upon
the completion of the Exchange Offer, the Company's obligations with respect to
the registration of the Old Debentures and the New Debentures will terminate. A
copy of the Registration Rights Agreement has been filed as an exhibit to the
Registration Statement of which this Prospectus is a part and the summary herein
of certain provisions thereof does not purport to be complete and is qualified
in its entirety by reference thereto. As a result of the filing and the
effectiveness of the Registration Statement, certain liquidated damages provided
for in the Registration Rights Agreement will not become payable by the Company.
Following the completion of the Exchange Offer (except as set forth in the
paragraph immediately below), holders of Old Debentures not tendered will not
have any further registration rights and those Old Debentures will continue to
be subject to certain restrictions on transfer. Accordingly, the liquidity of
the market for the Old Debentures could be adversely affected upon completion of
the Exchange Offer.
 
     In order to participate in the Exchange Offer, a holder must represent to
the Company, among other things, that (i) the New Debentures acquired pursuant
to the Exchange Offer are being obtained in the ordinary course of business of
the person receiving the New Debentures, (ii) neither the holder nor any such
other person is engaging in or intends to engage in a distribution of the New
Debentures, (iii) neither the holder nor any such other person has an
arrangement or understanding with any person to participate in the distribution
of the New Debentures and (iv) neither the holder nor any such other person is
an "affiliate," as defined under Rule 405 promulgated under the Securities Act,
of the Company. Pursuant to the Registration Rights Agreement, the Company is
required to file a "shelf" registration statement for a continuous offering
pursuant to Rule 415 under the Securities Act in respect of the Old Notes if (a)
it is prohibited from consummating the Exchange Offer because the Exchange Offer
is not permitted by applicable law or Commission policy or (b) any holder of
Transfer Restricted Securities (as defined) notifies the Company in writing
prior to the 20th business day following consummation of the Exchange Offer that
(i) based on an opinion of counsel, it is prohibited by law or Commission policy
from participating in the Exchange Offer or (ii) it is a broker-dealer and owns
Debentures acquired directly from the Issuer. In the event that the Company is
obligated to file a "shelf" registration statement, it will be required to keep
such "shelf" registration statement effective until the later of (a) the date on
which the Initial Purchaser is no longer deemed to be an Affiliate of the Issuer
and (b) the earlier of May 22, 2000 and such earlier date when no Transfer
Restricted Securities covered by such "shelf" registration statement remain
outstanding. Other than as set forth in this paragraph, no holder will have the
right to participate in the "shelf" registration statement
 
                                       53
<PAGE>   55
 
nor otherwise to require that the Company register such holder's shares of Old
Notes under the Securities Act. See "-- Procedures for Tendering."
 
     Based on an interpretation by the Commission's staff set forth in no-action
letters issued to third-parties unrelated to the Company, the Company believes
that, with the exceptions set forth below, New Debentures issued pursuant to the
Exchange Offer in exchange for Old Debentures may be offered for resale, resold
and otherwise transferred by any person receiving such New Debentures, whether
or not such person is the registered holder (other than any such holder or such
other person which is an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act) without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that the New
Debentures are acquired in the ordinary course of business of the holder or such
other person and neither the holder nor such other person has an arrangement or
understanding with any person to participate in the distribution of such New
Debentures. Any holder who tenders in the Exchange Offer for the purpose of
participating in a distribution of the New Debentures cannot rely on this
interpretation by the Commission's staff and must comply with the registration
and prospectus delivery requirements of the Securities Act in connection with a
secondary resale transaction. Each broker-dealer that receives New Debentures
for its own account in exchange for Old Debentures, where the Old Debentures
were acquired by such broker-dealer as a result of market-making activities or
other trading activities, must acknowledge that it will deliver a prospectus in
connection with any resale of such New Debentures. See "Plan of Distribution."
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     Following the completion of the Exchange Offer (except as set forth in the
second paragraph under "-- Purpose and Effect" above), holders of Old Debentures
not tendered will not have any further registration rights and those Old
Debentures will continue to be subject to certain restrictions on transfer.
Accordingly, the liquidity of the market for a holder's Old Debentures could be
adversely affected upon completion of the Exchange Offer if the holder does not
participate in the Exchange Offer.
 
TERMS OF THE EXCHANGE OFFER
 
     Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Old
Debentures validly tendered and not withdrawn prior to 5:00 p.m., New York City
time, on the Expiration Date. The Company will issue $1,000 principal amount at
maturity of New Debentures in exchange for each $1,000 principal amount at
maturity of outstanding Old Debentures accepted in the Exchange Offer. Holders
may tender some or all of their Old Debentures pursuant to the Exchange Offer.
However, Old Debentures may be tendered only in integral multiples of $1,000 in
principal amount.
 
     The form and terms of the New Debentures are substantially the same as the
form and terms of the Old Debentures except that the New Debentures have been
registered under the Securities Act and will not bear legends restricting their
transfer. The New Debentures will evidence the same debt as the Old Debentures
and will be issued pursuant to, and entitled to the benefits of, the Indenture
pursuant to which the Old Debentures were issued.
 
     As of May 31, 1998, Old Notes representing $174,000,000 aggregate principal
amount at maturity were outstanding and there was one registered holder, a
nominee of DTC. This Prospectus, together with the Letter of Transmittal, is
being sent to such registered Holder and to others believed to have beneficial
interests in the Old Debentures. 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 promulgated thereunder.
 
     The Company shall be deemed to have accepted validly tendered Old
Debentures when, as, and if the Company has given oral or written notice thereof
to the Exchange Agent. The Exchange Agent will act as agent for the tendering
holders for the purpose of receiving the New Debentures from the Company. If any
tendered Old Debentures 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 Old Debentures will be
 
                                       54
<PAGE>   56
 
returned, without expense, to the tendering holder thereof as promptly as
practicable after the Expiration Date.
 
     Holders who tender Old Debentures in the Exchange Offer will not be
required to pay brokerage commissions or fees or, subject to the instructions in
the Letter of Transmittal, transfer taxes with respect to the exchange of Old
Debentures 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 "The Exchange Offer -- Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
     The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
            , 1998, unless the Company, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date and time to which the Exchange Offer is extended. In order to extend the
Exchange Offer, the Company will issue a notice of any extension by press
release or other public announcement 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 accepting any
Old Debentures, to extend the Exchange Offer or, if any of the conditions set
forth under "The Exchange Offer -- Conditions to 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 (ii) to
amend the terms of the Exchange Offer in any manner.
 
PROCEDURES FOR TENDERING
 
     Only a holder of Old Debentures may tender the Old Notes in the Exchange
Offer. Except as set forth under "The Exchange Offer -- Book Entry Transfer," to
tender in the Exchange Offer a holder must complete, sign, and date the Letter
of Transmittal, or a copy thereof, have the signatures thereon guaranteed if
required by the Letter of Transmittal, and mail or otherwise deliver the Letter
of Transmittal or copy to the Exchange Agent prior to the Expiration Date. In
addition, either (i) certificates for such Old Debentures must be received by
the Exchange Agent along with the Letter of Transmittal, prior to the Expiration
Date or (ii) a timely confirmation of a book-entry transfer (a "Book-Entry
Confirmation") of such Old Debentures, if that procedure is available, into the
Exchange Agent's account at DTC (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 Expiration Date, or (iii) the holder must comply
with the guaranteed delivery procedures described below. To be tendered
effectively, the Letter of Transmittal and other required documents must be
received by the Exchange Agent at the address set forth under "The Exchange
Offer -- Exchange Agent" prior to the Expiration Date.
 
     The tender by a holder that is not withdrawn before the Expiration Date
will constitute an agreement between that 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 OLD DEBENTURES AND THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK
OF THE HOLDER. INSTEAD OF DELIVERY 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 EXPIRATION DATE. NO
LETTER OF TRANSMITTAL OR OLD DEBENTURES SHOULD BE SENT TO THE COMPANY. HOLDERS
MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST
COMPANIES, OR NOMINEES TO EFFECT THESE TRANSACTIONS FOR SUCH HOLDERS.
 
     Any beneficial owner whose Old Debentures are registered in the name of a
broker, dealer, commercial bank, trust company, or other nominee and who wishes
to tender should contact the registered holder promptly and instruct the
registered holder to tender on the beneficial owner's behalf. If the beneficial
owner wishes to tender on the owner's own behalf, the owner must, prior to
completing and executing the Letter of
                                       55
<PAGE>   57
 
Transmittal and delivering the owner's Old Debentures, either make appropriate
arrangements to register ownership of the Old Debentures in the beneficial
owner's name or obtain a properly completed bond power from the registered
holder. The transfer of registered ownership may take considerable time.
 
     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution (as defined below)
unless Old Debentures tendered pursuant thereto are tendered (i) by a registered
holder who has not completed the box entitled "Special Registration Instruction"
or "Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution. If signatures on a Letter of Transmittal or
a notice of withdrawal, as the case may be, are required to be guaranteed, the
guarantee must be by any eligible guarantor institution that is a member of or
participant in the Securities Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Program, the Stock Exchange Medallion
Program, or an "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Exchange Act (an "Eligible Institution").
 
     If the Letter of Transmittal is signed by a person other than the
registered holder of any Old Debentures listed therein, the Old Debentures must
be endorsed or accompanied by a properly completed bond power, signed by the
registered holder as that registered holder's name appears on the Old
Debentures.
 
     If the Letter of Transmittal or any Old Debentures 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 of their authority to so act must be submitted with
the Letter of Transmittal unless waived by the Company.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance, and withdrawal of tendered Old Debentures will be
determined by the Company in its sole discretion, which determination will be
final and binding. The Company reserves the absolute right to reject any and all
Old Debentures not properly tendered or any Old Debentures the Company's
acceptance of which would, in the opinion of counsel for the Company, be
unlawful. The Company also reserves the right to waive any defects,
irregularities, or conditions of tender as to particular Old Debentures. The
Company's interpretation of the terms and conditions of the Exchange Offer
(including the instructions in the Letter of Transmittal) will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Old Debentures must be cured within such time as the
Company shall determine. Although the Company intends to notify holders of
defects or irregularities with respect to tenders of Old Debentures, neither the
Company, the Exchange Agent, nor any other person shall incur any liability for
failure to give such notification. Tenders of Old Debentures will not be deemed
to have been made until such defects or irregularities have been cured or
waived. Any Old Debentures received by the Exchange Agent that are not properly
tendered and as to which the defects or irregularities have not been cured or
waived will be returned by the Exchange Agent to the tendering holders, unless
otherwise provided in the Letter of Transmittal, as soon as practicable
following the Expiration Date.
 
     In addition, the Company reserves the right in its sole discretion to
purchase or make offers for any Old Debentures that remain outstanding after the
Expiration Date or, as set forth under "The Exchange Offer -- Conditions to the
Exchange Offer," to terminate the Exchange Offer and, to the extent permitted by
applicable law, purchase Old Debentures in the open market, in privately
negotiated transactions, or otherwise. The terms of any such purchases or offers
could differ from the terms of the Exchange Offer.
 
     By tendering, each holder will represent to the Company that, among other
things, (i) the New Debentures acquired pursuant to the Exchange Offer are being
obtained in the ordinary course of business of the person receiving such New
Debentures, whether or not such person is the registered holder, (ii) neither
the holder nor any such other person is engaging in or intends to engage in a
distribution of such New Debentures, (iii) neither the holder nor any such other
person has an arrangement or understanding with any person to participate in the
distribution of such New Debentures, and (iv) neither the holder nor any such
other person is an "affiliate," as defined under Rule 405 of the Securities Act,
of the Company.
 
                                       56
<PAGE>   58
 
     In all cases, issuance of New Debentures for Old Debentures that are
accepted for exchange pursuant to the Exchange Offer will be made only after
timely receipt by the Exchange Agent of certificates for such Old Debentures or
a timely Book-Entry Confirmation of such Old Debentures into the Exchange
Agent's account at the Book-Entry Transfer Facility, a properly completed and
duly executed Letter of Transmittal (or, with respect to the DTC and its
participants, electronic instructions in which the tendering holder acknowledges
its receipt of and agreement to be bound by the Letter of Transmittal), and all
other required documents. If any tendered Old Debentures are not accepted for
any reason set forth in the terms and conditions of the Exchange Offer or if Old
Debentures are submitted for a greater principal amount than the holder desires
to exchange, such unaccepted or non-exchanged Old Debentures will be returned
without expense to the tendering Holder thereof (or, in the case of Old
Debentures 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 nonexchanged Old Debentures will be credited to an account
maintained with such Book-Entry Transfer Facility) as promptly as practicable
after the expiration or termination of the Exchange Offer.
 
     Each broker-dealer that receives New Debentures for its own account in
exchange for Old Debentures, where the Old Debentures were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such New Debentures. See "Plan of Distribution."
 
BOOK-ENTRY TRANSFER
 
     The Exchange Agent will make a request to establish an account with respect
to the Old Debentures at the Book-Entry Transfer Facility for purposes of the
Exchange Offer within two business days after the date of this Prospectus, and
any financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of Old Debentures being tendered
by causing the Book-Entry Transfer Facility to transfer such Old Debentures into
the Exchange Agent's account at the Book-Entry Transfer Facility in accordance
with such Book-Entry Transfer Facility's procedures for transfer. However,
although delivery of Old Debentures may be effected through book-entry transfer
at the Book-Entry Transfer Facility, the Letter of Transmittal or copy thereof,
with any required signature guarantees and any other required documents, must,
in any case other than as set forth in the following paragraph, be transmitted
to and received by the Exchange Agent at the address set forth under "The
Exchange Offer -- Exchange Agent" on or prior to the Expiration Date or the
guaranteed delivery procedures described below must be complied with.
 
     DTC's Automated Tender Offer Program ("ATOP") is the only method of
processing exchange offers through DTC. To accept the Exchange Offer through
ATOP, participants in DTC must send electronic instructions to DTC through DTC's
communication system in lieu of sending a signed, hard copy Letter of
Transmittal. DTC is obligated to communicate those electronic instructions to
the Exchange Agent. To tender Old Debentures through ATOP, the electronic
instructions sent to DTC and transmitted by DTC to the Exchange Agent must
contain the character by which the participant acknowledges its receipt of and
agrees to be bound by the Letter of Transmittal.
 
GUARANTEED DELIVERY PROCEDURES
 
     If a registered holder of the Old Debentures desires to tender such Old
Debentures and the Old Debentures are not immediately available, or time will
not permit such holder's Old Debentures or other required documents to reach the
Exchange Agent before the Expiration Date, or the procedure for book-entry
transfer cannot be completed on a timely basis, a tender may be effected if (i)
the tender is made through an Eligible Institution, (ii) prior to the Expiration
Date, the Exchange Agent received from such Eligible Institution a properly
completed and duly executed Letter of Transmittal (or a facsimile thereof) and
Notice of Guaranteed Delivery, substantially in the form provided by the Issuer
(by telegram, telex, facsimile transmission, mail or hand delivery), setting
forth the name and address of the holder of Old Debentures and the amount of Old
Debentures tendered, stating that the tender is being made thereby and
guaranteeing that within three New York Stock Exchange ("NYSE") trading days
after the date of execution of the Notice of Guaranteed Delivery, the
certificates for all physically tendered Old Debentures, in proper form for
transfer, or a Book-Entry Confirmation, as the case may be, and any other
documents required by the Letter of
                                       57
<PAGE>   59
 
Transmittal will be deposited by the Eligible Institution with the Exchange
Agent, and (iii) the certificates for all physically tendered Old Debentures, in
proper form for transfer, or a Book-Entry Confirmation, as the case may be, and
all other documents required by the Letter of Transmittal, are received by the
Exchange Agent within three NYSE trading days after the date of execution of the
Notice of Guaranteed Delivery.
 
WITHDRAWAL RIGHTS
 
     Tenders of Old Debentures may be withdrawn at any time prior to 5:00 pm.,
New York City time, on the Expiration Date.
 
     For a withdrawal of a tender of Old Debentures to be effective, a written
or (for DTC participants) electronic ATOP transmission notice of withdrawal must
be received by the Exchange Agent at its address set forth on the back cover
page of this Prospectus prior to 5:00 pm., New York City time, on the Expiration
Date. Any such notice of withdrawal must (i) specify the name of the person
having deposited the Old Debentures to be withdrawn (the "Depositor"), (ii)
identify the Old Debentures to be withdrawn (including the certificate number or
numbers and principal amount of such Old Debentures), (iii) be signed by the
holder in the same manner as the original signature on the Letter of Transmittal
by which such Old Debentures were tendered (including any required signature
guarantees) or be accompanied by documents of transfer sufficient to have the
Trustee register the transfer of such Old Debentures into the name of the person
withdrawing the tender, and (iv) specify the name in which any such Old
Debentures are to be registered, if different from that of the Depositor. All
questions as to the validity, form, and eligibility (including time of receipt)
of such notices will be determined by the Issuer, whose determination shall be
final and binding on all parties. Any Old Debentures so withdrawn will be deemed
not to have been validly tendered for exchange for purposes of the Exchange
Offer. Any Old Debentures which have been tendered for exchange but which are
not exchanged for any reason will be returned to the holder thereof without cost
to such holder as soon as practicable after withdrawal, rejection of tender, or
termination of the Exchange Offer. Properly withdrawn Old Debentures may be
retendered by following one of the procedures under "The Exchange Offer --
Procedures for Tendering" at any time on or prior to the Expiration Date.
 
CONDITIONS TO THE EXCHANGE OFFER
 
     Notwithstanding any other provision of the Exchange Offer, the Issuer shall
not be required to accept for exchange, or to issue New Debentures in exchange
for, any Old Debentures and may terminate or amend the Exchange Offer if at any
time before the acceptance of such Old Debentures for exchange or the exchange
of the New Debentures for such Old Debentures, the Issuer determines that the
Exchange Offer violates applicable law, any applicable interpretation of the
staff of the Commission or any order of any governmental agency or court of
competent jurisdiction.
 
     The foregoing conditions are for the sole benefit of the Issuer and may be
asserted by the Issuer regardless of the circumstances giving rise to any such
condition or may be waived by the Issuer in whole or in part at any time and
from time to time in its sole discretion. The failure by the Issuer at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right and each such right shall be deemed an ongoing right which may be asserted
at any time and from time to time.
 
     In addition, the Issuer will not accept for exchange any Old Debentures
tendered, and no New Debentures will be issued in exchange for any such Old
Debentures, if at such time any stop order shall be threatened or in effect with
respect to the Registration Statement of which this Prospectus constitutes a
part or the qualification of the Indenture under the Trust Indenture Act of
1939, as amended (the "TIA"). In any such event the Issuer is required to use
every reasonable effort to obtain the withdrawal of any stop order at the
earliest possible time.

FEES AND EXPENSES
 
     The Issuer will not make any payments to brokers, dealers, or others
soliciting acceptances of the Exchange Offer. The principal solicitation is
being made by mail; however, additional solicitations may be made in person or
by telephone by officers and employees of the Issuer.
 
     The estimated cash expenses to be incurred in connection with the Exchange
Offer will be paid by the Issuer and are estimated in the aggregate to be
$          , which includes fees and expenses of the Exchange Agent, accounting,
legal, printing, and related fees and expenses.
 
TRANSFER TAXES
 
     Holders who tender their Old Debentures for exchange will not be obligated
to pay any transfer taxes in connection therewith, except that holders who
instruct the Issuer to register New Debentures in the name of, or request that
Old Debentures not tendered or not accepted in the Exchange Offer be returned
to, a person other than the registered tendering holder will be responsible for
the payment of any applicable transfer tax thereon.
 
BOOK-ENTRY; DELIVERY AND FORM
 
     Except as described in the next paragraph, the New Debentures initially
will be represented by one or more permanent global certificates in definitive,
duly registered form (the "Global Debentures"). The Global Debentures will be
deposited on the Issue Date with, or on behalf of, The Depository Trust Company,
New York, New York ("DTC") and registered in the name of a nominee of DTC.
 
     The Global Debentures. The Issuer expects that pursuant to procedures
established by DTC (i) upon the issuance of the Global Debentures, DTC or its
custodian will credit, on its internal system, the principal amount of New
Debentures of the individual beneficial interests represented by such Global
Debentures to the respective accounts of persons who have accounts with such
depositary and (ii) ownership of beneficial interests in the Global Debentures
will be shown on, and the transfer of such ownership will be effected only
through, records maintained by DTC or its nominee (with respect to interests of
participants) and the records of participants (with respect to interests of
persons other than participants). Such accounts initially will be designated by
or on behalf of the Initial Purchaser and ownership of beneficial interests in
the Global Debentures will be limited to persons who have accounts with DTC
("participants") or persons who hold
 
                                       59
<PAGE>   61
 
interests through participants. QIBs and institutional Accredited Investors who
are not QIB's may hold their interests in the Global Debentures directly through
DTC if they are participants in such system, or indirectly through organizations
which are participants in such system.
 
     So long as DTC, or its nominee, is the registered owner or holder of the
New Debentures, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the New Debentures represented by such Global Debentures
for all purposes under the Indenture. No beneficial owner of an interest in the
Global Debentures will be able to transfer that interest except in accordance
with DTC's procedures.
 
     Payments of the principal of, premium (if any) and interest on, the Global
Debentures will be made to DTC or its nominee, as the case may be, as the
registered owner thereof. None of the Issuer, the Trustee or any Paying Agent
will have any responsibility or liability for any aspect of the records relating
to or payments made on account of beneficial ownership interests in the Global
Debentures or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interest.
 
     The Issuer expects that DTC or its nominee, upon receipt of any payment of
principal, premium, if any and interest on the Global Debentures, will credit
participants' accounts with payments in amount proportionate to their respective
beneficial interests in the principal amount of the Global Debentures as shown
on the records of DTC or its nominee. The Issuer also expects that payments by
participants to owners of beneficial interests in the Global Debentures held
through such participants will be governed by standing instructions and
customary practice, as is now the case with securities held for the accounts of
customers registered in the names of nominees for such customers. Such payments
will be the responsibility of such participants.
 
     Transfers between participants in DTC will be effected in the ordinary way
through DTC's same-day funds system in accordance with DTC rules and will be
settled in same day funds. If a holder requires physical delivery of a
Certificated Security for any reason, including to sell New Debentures to
persons in states which require physical delivery of the New Debentures, or to
pledge such securities, such holder must transfer its interest in a Global Note,
in accordance with the normal procedures of DTC.
 
     DTC has advised the Issuer that it will take any action permitted to be
taken by a holder of New Debentures (including the presentation of New
Debentures for exchange as described below) only at the direction of one or more
participants to whose account the DTC interests in the Global Debentures are
credited and only in respect of such portion of the aggregate principal amount
of New Debentures as to which such participant or participants has or have given
such direction.
 
     DTC has advised the Issuer as follows: DTC is a limited purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the
Uniform Commercial Code and a "Clearing Agency" registered pursuant to the
provisions of Section 17A of the Securities Exchange Act of 1934, as amended.
DTC was created to hold securities for its participants and facilitate the
clearance and settlement of securities transactions between participants through
electronic book-entry changes in accounts of its participants, thereby
eliminating the need for physical movement of certificates. Participants include
securities brokers and dealers, banks, trust companies and clearing corporations
and certain other organizations. Indirect access to the DTC system is available
to others such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a participant, either directly or
indirectly ("indirect participants").
 
     Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the Global Debentures among participants of DTC, it is
under no obligation to perform such procedures, and such procedures may be
discontinued at any time. Neither the Issuer nor the Trustee will have any
responsibility for the performance by DTC or its participants or indirect
participants of their respective obligations under the rules and procedures
governing their operations.
 
     Certificated Securities. If DTC is at any time unwilling or unable to
continue as a depositary for the Global Debentures and a successor depositary is
not appointed by the Issuer within 90 days, Certificated Securities will be
issued in exchange for the Global Debentures.

                       DESCRIPTION OF NEW CREDIT FACILITY
 
     The New Credit Facility has been provided by a syndicate of banks and other
financial institutions led by Donaldson, Lufkin & Jenrette Securities
Corporation, as arranger (the "Arranger"), DLJ Capital Funding, Inc., as
syndication agent (the "Syndication Agent"), ABN AMRO Bank N.V., Chicago Branch,
as administrative agent (the "Administrative Agent"), and Societe Generale, as
documentation agent. The New Credit Facility includes a $330 million term loan
facility (the "Term Loan Facility") and a $100 million revolving credit facility
(subject to adjustment as provided below), which provides for revolving loans
and up to $50 million of letters of credit (the "Revolving Credit Facility").
The Term Loan Facility is comprised of a term A facility of $100 million (the
"Term A Facility"), which has a maturity of six years, a term B facility of $115
million (the "Term B Facility"), which has a maturity of seven years, and a term
C facility of $115 million (the "Term C Facility"), which has a maturity of
eight years. The Revolving Credit Facility terminates six years after the date
of initial funding of the New Credit Facility and is subject to a potential, but
uncommitted, increase of up to $25 million at Thermadyne LLC's request at any
time prior to such sixth anniversary. Such increase is available only if one or
more financial institutions agrees, at the time of Thermadyne LLC's request, to
provide it.
 
     The New Credit Facility generally bears interest, at Thermadyne LLC's
option, at the Administrative Agent's alternate base rate or at the
reserve-adjusted London Interbank Offered Rate ("LIBOR") plus, in each case,
applicable margins of (i) in the case of alternate base rate loans, (x) 1.00%
for revolving and Term A loans, (y) 1.25% for Term B loans and (z) 1.50% for
Term C loans and (ii) in the case of LIBOR loans, (x) 2.25% for revolving and
Term A loans, (y) 2.50% for Term B loans and (z) 2.75% for Term C loans.
 
     Thermadyne LLC pays a commitment fee calculated at a rate of 0.50% per
annum on the daily average unused commitment under the Revolving Credit Facility
(whether or not then available). Such fee is payable quarterly in arrears and
upon termination of the Revolving Credit Facility (whether at stated maturity or
otherwise).
 
     Beginning six months after the consummation of the Merger and the Merger
Financing, the applicable margins for the Term A Facility and the Revolving
Credit Facility, as well as the commitment fee and letter of credit fee, is
subject to possible reductions based on the ratio of consolidated Debt to EBITDA
(each as defined in the New Credit Facility).
 
     Thermadyne LLC pays a letter of credit fee calculated (i) in the case of
standby letters of credit, at a rate per annum equal to the then applicable
margin for LIBOR loans under the Revolving Credit Facility minus 0.125% and (ii)
in the case of documentary letters of credit, at a rate per annum equal to 1.25%
plus, in each case, a fronting fee on the stated amount of each letter of
credit. Such fees are payable quarterly in arrears. In addition, Thermadyne LLC
pays customary transaction charges in connection with any letters of credit.
 
     The Term Loan Facility is subject to the following amortization schedule:

(as defined in the New Credit Facility) exceeds 3.5 to 1.0, and (iv) with 50% of
the net cash proceeds from the issuance of equity to the extent that the
Leverage Ratio exceeds 4.0 to 1.0. Thermadyne LLC's obligations under the New
Credit Facility are secured by a first-priority perfected lien on: (i)
substantially all domestic property and assets, tangible and intangible (other
than accounts receivable sold or to be sold into the accounts receivable program
and short term real estate leases), of Thermadyne LLC and its domestic
subsidiaries (other than the special purpose subsidiaries involved in the
accounts receivable program); (ii) the capital stock of (a) Thermadyne LLC held
by Holdings and (b) all subsidiaries of the Issuer (provided that no more than
65% of the equity interest in non-U.S. subsidiaries held by the Issuer and its
domestic subsidiaries and no equity interests in subsidiaries held by foreign
subsidiaries are required to be pledged as a security); and (iii) all
intercompany indebtedness. Holdings has guaranteed the obligations of Thermadyne
LLC under the New Credit Facility. In addition, obligations under the New Credit
Facility are guaranteed by all domestic subsidiaries.
 
     The New Credit Facility contains customary covenants and restrictions on
Thermadyne LLC's ability to engage in certain activities, including, but not
limited to: (i) limitations on the incurrence of liens and indebtedness, (ii)
restrictions on sale lease-back transactions, consolidations, mergers, sale of
assets, capital expenditures, transactions with affiliates and investments, and
(iii) severe restrictions on dividends, and other similar distributions.
 
     The New Credit Facility contains financial covenants requiring Thermadyne
LLC to maintain a minimum level of adjusted EBITDA (as defined in the New Credit
Facility); a minimum Interest Coverage Ratio (as defined in the New Credit
Facility); a minimum Fixed Charge Coverage Ratio (as defined in the New Credit
Facility); and a maximum Leverage Ratio (as defined in the New Credit Facility).
 
                    DESCRIPTION OF SENIOR SUBORDINATED NOTES
 
     Thermadyne Mfg. LLC and Thermadyne Capital Corp. have outstanding $207
aggregate principal amount of the Senior Subordinated Notes. The Senior
Subordinated Notes were issued pursuant to the Notes Indenture among Thermadyne
Mfg., Thermadyne Capital and State Street Bank and Trust Company, as trustee. A
copy of the Notes Indenture has been filed as an exhibit to the Registration
Statement of which this Prospectus is a part and the summary herein of certain
provisions thereof does not purport to be complete and is qualified in its
entirety by reference thereto, including the definitions therein of certain
terms used below.
 
     The Senior Subordinated Notes are general unsecured obligations of
Thermadyne Mfg. and Thermadyne Capital and will be subordinated in right of
payment to all existing and future Senior Indebtedness of Thermadyne Mfg. and
Thermadyne Capital (including borrowings under the New Credit Facility). The
Senior Subordinated Notes are unconditionally guaranteed on a senior
subordinated basis by certain of Thermadyne Mfg.'s existing domestic
subsidiaries. The Note Guarantees will be general unsecured obligations of the
Guarantors, will be subordinated in right of payment to all existing and future
Senior Indebtedness of the Guarantors, including indebtedness under the New
Credit Facility, and will rank senior in right of payment to any future
subordinated indebtedness of the Guarantors.
 
     All of Thermadyne Mfg.'s Subsidiaries (other than Thermadyne Capital and
Thermadyne Receivables, Inc.) are Restricted Subsidiaries. However, under
certain circumstances, Thermadyne Mfg. will be permitted to designate current or
future Subsidiaries as Unrestricted Subsidiaries. Unrestricted Subsidiaries will
not be subject to the restrictive covenants set forth in the Notes Indenture.
 
     The Senior Subordinated Notes mature on June 1, 2008. Interest on the
Senior Subordinated Notes will accrue at the rate of 9 7/8% per annum and will
be payable semi-annually in arrears on June 1 and December 1, commencing on
December 1, 1998, to Holders of record on the immediately preceding May 15 and
November 15.
 
     The payment of Subordinated Note Obligations will be subordinated in right
of payment, as set forth in the Notes Indenture, to the prior payment in full in
cash or cash equivalents of all Senior Indebtedness, whether outstanding on the
date of the Notes Indenture or thereafter incurred.
 
                                       62
<PAGE>   64
 
     Thermadyne Mfg.'s payment obligations under the Senior Subordinated Notes
are jointly and severally guaranteed (the "Note Guarantees") by the Guarantors.
The Note Guarantee of each Guarantor will be subordinated to the prior payment
in full in cash or cash equivalents of all Senior Indebtedness of such Guarantor
(including such Guarantor's guarantee of the New Credit Facility) to the same
extent that the Senior Subordinated Notes are subordinated to Senior
Indebtedness of the Company. The obligations of each Guarantor under its Note
Guarantee will be limited so as not to constitute a fraudulent conveyance under
applicable law.
 
     Except as provided below, the Senior Subordinated Notes are not redeemable
at the option of Thermadyne Mfg. and Thermadyne Capital prior to June 1, 2003.
Thereafter, the Senior Subordinated Notes are subject to redemption at any time
at the option of Thermadyne Mfg. and Thermadyne Capital, in whole or in part, in
cash at a redemption price declining from 104.938% of the principal amount
thereof during the 12-month period beginning June 1, 2003 to 100% of the
principal amount thereof on or after June 1, 2006, plus accrued and unpaid
interest and Liquidated Damages, if any, thereon to the applicable redemption
date.
 
     Notwithstanding the foregoing, on or prior to June 1, 2001, Thermadyne Mfg.
and Thermadyne Capital may redeem up to 35% of the aggregate principal amount of
Senior Subordinated Notes ever issued under the Notes Indenture in cash at a
redemption price of 109.875% of the principal amount thereof, plus accrued and
unpaid interest and Liquidated Damages, if any, thereon to the redemption date,
with the net cash proceeds of one or more Public Equity Offerings; provided that
at least 65% of the aggregate principal amount of Senior Subordinated Notes ever
issued under the Notes Indenture remains outstanding immediately after the
occurrence of any such redemption; and provided further that such redemption
shall occur within 90 days of the date of the closing of any such Public Equity
Offering.
 
     In addition, at any time prior to June 1, 2003, Thermadyne Mfg. and
Thermadyne Capital may, at their option upon the occurrence of a Change of
Control, redeem the Senior Subordinated Notes, in whole but not in part, upon
not less than 30 nor more than 60 days' prior notice (but in no event may any
such redemption occur more than 60 days after the occurrence of such Change of
Control), in cash at a redemption price equal to (i) the present value of the
sum of all the remaining interest (excluding accrued and unpaid interest, if
any), premium and principal payments that would become due on the Senior
Subordinated Notes as if the Senior Subordinated Notes were to remain
outstanding and be redeemed on June 1, 2003, computed using a discount rate
equal to the Treasury Rate plus 50 basis points, plus (ii) accrued and unpaid
interest and Liquidated Damages, if any, to the date of redemption.
 
     Upon the occurrence of a Change of Control, each Holder of Senior
Subordinated Notes will have the right to require Thermadyne Mfg. and Thermadyne
Capital to repurchase all or any part (equal to $1,000 or an integral multiple
thereof) of such Holder's Senior Subordinated Notes at an offer price in cash
equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid
interest and Liquidated Damages, if any, thereon to the date of repurchase.
 
     The Notes Indenture contains certain covenants that, among other things,
limit the ability of Thermadyne Mfg. and Thermadyne Capital and their Restricted
Subsidiaries to: incur indebtedness and issue preferred stock, repurchase
Capital Stock and Indebtedness subordinated to the Senior Subordinated Notes,
engage in transactions with affiliates, engage in sale and leaseback
transactions, incur or suffer to exist certain liens, pay dividends or other
distributions, make investments, sell assets and engage in certain mergers and
consolidations.
 
     The Notes Indenture provides that each of the following constitutes an
Event of Default: (a) default for 30 days in the payment when due of interest
on, or Liquidated Damages with respect to, the Senior Subordinated Notes
(whether or not prohibited by the subordination provisions of the Indenture);
(b) default in payment when due of the principal of or premium, if any, on the
Senior Subordinated Notes (whether or not prohibited by the subordination
provisions of the Notes Indenture); (c) failure by Thermadyne Mfg. or any of its
Restricted Subsidiaries for 30 days after receipt of notice from the Trustee or
Holders of at least 25% in principal amount of the Senior Subordinated Notes
then outstanding to comply with certain covenants contained in the Notes
Indenture (d) failure by Thermadyne Mfg. for 60 days after notice from the
Trustee or the Holders of at least 25% in principal amount of the Senior
Subordinated Notes then outstanding to comply
 
                                       63
<PAGE>   65
 
with any of its other agreements in the Notes Indenture or the Senior
Subordinated Notes; (e) default under any mortgage, indenture or instrument
under which there may be issued or by which there may be secured or evidenced
any Indebtedness for money borrowed by Thermadyne Mfg. or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by Thermadyne Mfg. or any of
its Restricted Subsidiaries), whether such Indebtedness or guarantee now exists,
or is created after the date of the Notes Indenture, which default (i) is caused
by a failure to pay Indebtedness at its stated final maturity (after giving
effect to any applicable grace period provided in such Indebtedness) (a "Payment
Default") or (ii) results in the acceleration of such Indebtedness prior to its
stated final maturity and, in each case, the principal amount of any such
Indebtedness, together with the principal amount of any other such Indebtedness
under which there has been a Payment Default or the maturity of which has been
so accelerated, aggregates $10.0 million or more; (f) failure by Thermadyne Mfg.
or any of its Restricted Subsidiaries to pay final judgments aggregating in
excess of $10.0 million (net of any amounts with respect to which a reputable
and creditworthy insurance company has acknowledged liability in writing), which
judgments are not paid, discharged or stayed for a period of 60 days; (g) except
as permitted by the Notes Indenture, any Note Guarantee shall be held in any
judicial proceeding to be unenforceable or invalid or shall cease for any reason
to be in full force and effect or any Guarantor, or any Person acting of behalf
of any Guarantor, shall deny or disaffirm its obligations under its Note
Guarantee; and (h) certain events of bankruptcy or insolvency with respect to
Thermadyne Mfg. or any of its Restricted Subsidiaries that is a Significant
Subsidiary.
 
     If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Senior
Subordinated Notes may declare all the Senior Subordinated Notes to be due and
payable immediately; provided that, so long as any Indebtedness permitted to be
incurred pursuant to the New Credit Facility shall be outstanding, such
acceleration shall not be effective until the earlier of (a) an acceleration of
any such Indebtedness under the New Credit Facility or (b) five business days
after receipt by Thermadyne Mfg. and Thermadyne Capital and the administrative
agent under the New Credit Facility of written notice of such acceleration.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency with respect to Thermadyne Mfg. or
any Significant Subsidiary, all outstanding Senior Subordinated Notes will
become due and payable without further action or notice. Holders of the Senior
Subordinated Notes may not enforce the Notes Indenture or the Senior
Subordinated Notes except as provided in the Notes Indenture. In the event of a
declaration of acceleration of the Senior Subordinated Notes because an Event of
Default has occurred and is continuing as a result of the acceleration of any
Indebtedness described in clause (e) of the preceding paragraph, the declaration
of acceleration of the Senior Subordinated Notes shall be automatically annulled
if the holders of any Indebtedness described in clause (e) have rescinded the
declaration of acceleration in respect of such Indebtedness within 30 days of
the date of such declaration and if (i) the annulment of the acceleration of the
Senior Subordinated Notes would not conflict with any judgment or decree of a
court of competent jurisdiction and (ii) all existing Events of Default, except
non-payment of principal or interest on the Senior Subordinated Notes that
became due solely because of the acceleration of the Senior Subordinated Notes,
have been cured or waived.

                         DESCRIPTION OF NEW DEBENTURES
 
GENERAL
 
     The New Debentures will be issued pursuant to an Indenture (the
"Indenture") among the Issuer and IBJ Schroder Bank & Trust Company, as trustee
(the "Trustee"). The terms of the New Debentures 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"). The New
Debentures are subject to all such terms, and Holders of New Debentures are
referred to the Indenture and the Trust Indenture Act for a statement thereof. A
copy of the Indenture has been filed as an exhibit to the Registration Statement
of which this Prospectus is a part and the summary herein of certain provisions
thereof does not purport to be complete and is qualified in its entirety by
reference thereto. The definitions of certain terms used in the following
summary are set forth below under "-- Certain Definitions."
 
     The New Debentures are general unsecured obligations of the Issuer and are
senior in right of payment to all future Indebtedness of the Issuer that is
subordinated to the New Debentures and pari passu in right of payment with all
future Indebtedness of the Issuer that is not subordinated to the New
Debentures. The Issuer is the sole obligor with respect to the Debentures;
moreover, the operations of the Issuer are conducted entirely through its
Subsidiaries and, therefore, the Issuer is completely dependent upon the
operations and cash flow of its Subsidiaries to meet its obligations, including
its obligations under the New Debentures. The New Credit Facility and the Senior
Subordinated Notes restrict Thermadyne LLC from paying any dividends or making
any other distributions to the Issuer. The ability of Thermadyne LLC to comply
with the conditions in the Senior Subordinated Notes may be affected by certain
events that are beyond the Issuer's control. The Debentures are effectively
subordinated to all Indebtedness and other liabilities (including, without
limitation, trade payables and lease obligations) of the Issuer's Subsidiaries,
including, without limitation, to Thermadyne LLC's obligations under the New
Credit Facility and the Senior Subordinated Notes. Any right of the Issuer to
receive assets of any of its Subsidiaries upon such Subsidiary's liquidation or
reorganization (and the consequent right of Holders of the Senior Subordinated
Notes to participate in those assets) is effectively subordinated to the claims
of that Subsidiary's creditors except to the extent that the Issuer itself is
recognized as a creditor of such Subsidiary, in which case the claims of the
Issuer would still be subordinate to the claims of such creditors who hold
security in the assets of such Subsidiary and to the claims of such creditors
who hold Indebtedness of such Subsidiary senior to that held by the Issuer. On a
pro forma basis giving effect to the Merger, including the Merger Financing and
the application of the proceeds therefrom, as of March 31, 1998, the Issuer
would have had outstanding approximately $682.0 million of Indebtedness and the
Issuer's Subsidiaries would have had approximately $733.2 million of liabilities
outstanding, including Indebtedness under the Senior Subordinated Notes and the
New Credit Facility and including trade payables. The Indenture permits the
incurrence of certain additional Indebtedness of the Issuer and the Issuer's
Subsidiaries in the future. See "-- Certain Covenants -- Incurrence of
Indebtedness and Issuance of Preferred Stock."
 
     Substantially all of the Issuer's Subsidiaries (other than Thermadyne
Receivables, Inc.) are Restricted Subsidiaries. However, under certain
circumstances, the Issuer will be permitted to designate current or future
Subsidiaries as Unrestricted Subsidiaries. Unrestricted Subsidiaries will not be
subject to the restrictive covenants set forth in the Indenture.
 
PRINCIPAL, MATURITY AND INTEREST
 
     The New Debentures initially will be limited in aggregate principal amount
at maturity to $174 million and will mature on June 1, 2008. The New Debentures
will be issued at a substantial discount from their principal amount at
maturity. Until June 1, 2003, no interest will accrue on the New Debentures, but
the Accreted Value will increase (representing amortization of original issue
discount) between the date of original issuance and June 1, 2003, on a
semi-annual bond equivalent basis using a 360-day year comprised of twelve
30-day months, such that the Accreted Value shall be equal to the full principal
amount at maturity of the New Debentures on June 1, 2003. Beginning on June 1,
2003, interest on the New Debentures will accrue at the rate of 12 1/2% per
annum and will be payable in cash semi-annually in arrears on June 1 and
December 1, commencing on December 1, 2003, to Holders of record on the
immediately preceding May 15
 
                                       65
<PAGE>   67
 
and November 15. Interest on the New Debentures will accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from June
1, 2003. Interest will be computed on the basis of a 360-day year comprised of
twelve 30-day months. Principal of, premium, if any, and interest and Liquidated
Damages, if any, on the New Debentures will be payable at the office or agency
of the Issuer maintained for such purpose within the City and State of New York
or, at the option of the Issuer, payment of interest and Liquidated Damages may
be made by check mailed to the Holders of the New Debentures at their respective
addresses set forth in the register of Holders of New Debentures; provided that
all payments of principal, premium, interest and Liquidated Damages with respect
to New Debentures represented by one or more permanent global New Debentures
will be paid by wire transfer of immediately available funds to the account of
The Depository Trust Company or any successor thereto. Until otherwise
designated by the Issuer, the Issuer's office or agency in New York will be the
office of the Trustee maintained for such purpose. The New Debentures will be
issued in denominations of $1,000 and integral multiples thereof.
 
     Subject to the covenants described below, the Issuer may issue additional
notes under the Indenture having the same terms in all respects as the New
Debentures (or in all respects except for the payment of interest on the New
Debentures (i) scheduled and paid prior to the date of issuance of such notes or
(ii) payable on the first Interest Payment Date following such date of
issuance). The New Debentures and any such additional notes would be treated as
a single class for all purposes under the Indenture.
 
OPTIONAL REDEMPTION
 
     Except as provided below, the New Debentures will not be redeemable at the
Issuer's option prior to June 1, 2003. Thereafter, the New Debentures will be
subject to redemption at any time at the option of the Issuer, in whole or in
part, upon not less than 30 nor more than 60 days' notice, in cash at the
redemption prices (expressed as percentages of principal amount at maturity) set
forth below, plus accrued and unpaid interest and Liquidated Damages, if any,
thereon to the applicable redemption date, if redeemed during the twelve-month
period beginning on June 1 of the years indicated below:

</TABLE>
 
     Notwithstanding the foregoing, on or prior to June 1, 2001, the Issuer may
redeem up to 100% of the aggregate principal amount at maturity of Debentures
ever issued under the Indenture in cash at a redemption price of 112.50% of the
Accreted Value thereof, plus Liquidated Damages, if any, thereon to the
redemption date, with the net cash proceeds of one or more Public Equity
Offerings; provided that, in the event that the Issuer redeems less than 100% of
the then outstanding Debentures, at least 60% of the aggregate principal amount
at maturity of Debentures ever issued under the Indenture remains outstanding
immediately after the occurrence of any such redemption; and provided further
that such redemption shall occur within 90 days of the date of the closing of
any such Public Equity Offering.
 
     In addition, at any time prior to June 1, 2003, the Issuer may, at its
option upon the occurrence of a Change of Control, redeem the New Debentures, in
whole but not in part, upon not less than 30 nor more than 60 days' prior notice
(but in no event may any such redemption occur more than 60 days after the
occurrence of such Change of Control), in cash at a redemption price equal to
(i) the present value of the sum of all the remaining premium and principal
payments that would become due on the New Debentures as if the New Debentures
were to remain outstanding and be redeemed on June 1, 2003, computed using a
discount rate equal to the Treasury Rate plus 50 basis points, plus (ii)
Liquidated Damages, if any, to the date of redemption.
 
     "Treasury Rate" means, as of any redemption date, the yield to maturity as
of such redemption date of United States Treasury securities with a constant
maturity (as compiled and published in the most recent Federal Reserve
Statistical Release H.15 (519) that has become publicly available at least two
Business Days prior to the redemption date (or, if such Statistical Release is
no longer published, any publicly available
 
                                       66

source of similar market data)) most nearly equal to the period from the
redemption date to June 1, 2003; provided that if the period from the redemption
date to June 1, 2003 is less than one year, the weekly average yield on actually
traded United States Treasury securities adjusted to a constant maturity of one
year shall be used.
 
SELECTION AND NOTICE
 
     If less than all of the Debentures are to be redeemed at any time,
selection of New Debentures for redemption will be made by the Trustee in
compliance with the requirements of the principal national securities exchange,
if any, on which the New Debentures are listed, or, if the New Debentures are
not so listed, on a pro rata basis, by lot or by such method as the Trustee
shall deem fair and appropriate; provided that no New Debentures having a
principal amount at maturity of $1,000 or less shall be redeemed in part.
Notices of redemption shall be mailed by first class mail at least 30 but not
more than 60 days before the redemption date to each Holder of New Debentures to
be redeemed at its registered address. Notices of redemption may not be
conditional. If any New Debenture is to be redeemed in part only, the notice of
redemption that relates to such New Debenture shall state the portion of the
principal amount at maturity thereof to be redeemed. A new New Debenture in
principal amount at maturity equal to the unredeemed portion thereof will be
issued in the name of the Holder thereof upon cancellation of the original New
Debenture. New Debentures called for redemption become due on the date fixed for
redemption. On and after the redemption date, interest ceases to accrue on New
Debentures or portions of them called for redemption.
 
MANDATORY REDEMPTION
 
     The Issuer is not required to make mandatory redemption of, or sinking fund
payments with respect to, the New Debentures.
 
REPURCHASE AT THE OPTION OF HOLDERS
 
  CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, each Holder of New Debentures
will have the right to require the Issuer to repurchase all or any part (equal
to $1,000 principal amount at maturity or an integral multiple thereof) of such
Holder's New Debentures pursuant to the offer described below (the "Change of
Control Offer") at an offer price in cash equal to 101% of the aggregate
principal amount at maturity thereof, plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the date of repurchase (or, in the case
of repurchases of New Debentures prior to June 1, 2003, at a purchase price
equal to 101% of the Accreted Value thereof, plus Liquidated Damages, if any,
thereon as of the date of redemption) (the "Change of Control Payment"). Within
65 days following any Change of Control, the Issuer will (or will cause the
Trustee to) mail a notice to each Holder describing the transaction or
transactions that constitute the Change of Control and offering to repurchase
New Debentures, pursuant to the procedures required by the Indenture and
described in such notice. The Issuer 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 the New Debentures as a result of a Change of Control. To
the extent that the provisions of any securities laws or regulations conflict
with the provisions of the Indenture relating to such Change of Control Offer,
the Issuer will comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations described in the Indenture
by virtue thereof.
 
     On the Change of Control Payment Date, the Issuer will, to the extent
lawful, (a) accept for payment all New Debentures or portions thereof properly
tendered pursuant to the Change of Control Offer, (b) deposit with the Paying
Agent an amount equal to the Change of Control Payment in respect of all New
Debentures or portions thereof so tendered and (c) deliver or cause to be
delivered to the Trustee the New Debentures so accepted together with an
Officers' Certificate stating the aggregate principal amount at maturity of
Debentures or portions thereof being purchased by the Issuer. The Paying Agent
will promptly mail to each Holder of New Debentures so tendered the Change of
Control Payment for such New Debentures, and the
 
                                       67
<PAGE>   69
 
Trustee will promptly authenticate and mail (or cause to be transferred by
book-entry) to each Holder a new New Debenture equal in principal amount at
maturity to any unpurchased portion of the New Debentures surrendered, if any;
provided that each such new New Debenture will be in a principal amount at
maturity of $1,000 or an integral multiple thereof. The Issuer 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 Indenture provides that, the Issuer will fix the Change of Control
Payment Date no earlier than 30 but no more than 60 days after the Change of
Control Offer is mailed as set forth above. Prior to complying with the
provisions of the preceding sentence, but in any event within 60 days following
a Change of Control, the Issuer will either repay all outstanding Indebtedness
of its Subsidiaries or obtain the requisite consents, if any, under all
agreements governing all such outstanding Indebtedness of its Subsidiaries to
permit the repurchase of the Debentures required by this covenant. The New
Credit Facility and the Senior Subordinated Notes restrict Thermadyne LLC from
paying any dividends or making any other distributions to the Issuer. If the
Issuer does not obtain the consent of the lenders under agreements governing
outstanding Indebtedness of its Subsidiaries, including under the New Credit
Facility and the Senior Subordinated Notes, to permit the repurchase of the
Debentures or does not refinance such Indebtedness, the Issuer will likely not
have the financial resources to purchase Debentures and the Issuer's
Subsidiaries will be restricted by the terms of such Indebtedness from paying
dividends to the Issuer or otherwise lending or distributing funds to the Issuer
for the purpose of such purchase. In any event, there can be no assurance that
the Issuer's Subsidiaries will have the resources available to pay any such
dividend or make any such distribution. The Issuer's failure to make a Change of
Control Offer when required or to purchase tendered Debentures when tendered
would constitute an Event of Default under the Indenture. See "Risk Factors."
 
     The Change of Control provisions described above will be applicable whether
or not any other provisions of the Indenture are applicable. Except as described
above with respect to a Change of Control, the Indenture does not contain
provisions that permit the Holders of the New Debentures to require that the
Issuer repurchase or redeem the New Debentures in the event of a takeover,
recapitalization or similar transaction.
 
     The Issuer will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in the Indenture applicable to a Change of Control Offer made by the Issuer and
purchases all New Debentures validly tendered and not withdrawn under such
Change of Control Offer.
 
     "Change of Control" means the occurrence of any of the following: (a) the
sale, lease, transfer, conveyance or other disposition (other than by way of
merger or consolidation), in one or a series of related transactions, of all or
substantially all of the assets of the Issuer and its Subsidiaries, taken as a
whole, to any "person" or "group" (as such terms are used in Section 13(d) of
the Exchange Act), other than the Principals and their Related Parties; (b) the
adoption of a plan for the liquidation or dissolution of the Issuer, (c) the
consummation of any transaction (including, without limitation, any merger or
consolidation) the result of which is that any "person" or "group" (as such
terms are used in Section 13(d) of the Exchange Act), other than the Principals
and their Related Parties, becomes the "beneficial owner" (as such term is
defined in Rule 13d-3 and Rule 13d-5 under the Exchange Act), directly or
indirectly through one or more intermediaries, of 50% or more of the voting
power of the outstanding voting stock of the Issuer; or (d) the first day on
which a majority of the members of the Board of Directors of the Issuer are not
Continuing Directors.
 
     The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the assets of the Issuer and its Subsidiaries taken as a whole. Although
there is a developing body of case law interpreting the phrase "substantially
all," there is no precise established definition of the phrase under applicable
law. Accordingly, the ability of a Holder of New Debentures to require the
Issuer to repurchase such New Debentures as a result of a sale, lease, transfer,
conveyance or other disposition of less than all of the assets of the Issuer and
its Subsidiaries taken as a whole to another Person or group may be uncertain.
 
     "Continuing Directors" means, as of any date of determination, any member
of the Board of Directors of the Issuer who (a) was a member of such Board of
Directors immediately after consummation of the Merger
 
                                       68
<PAGE>   70
 
or (b) was nominated for election or elected to such Board of Directors with the
approval of, or whose election to the Board of Directors was ratified by, at
least a majority of the Continuing Directors who were members of such Board of
Directors at the time of such nomination or election.
 
  ASSET SALES
 
     The Indenture provides that the Issuer will not, and will not permit any of
its Restricted Subsidiaries to, consummate an Asset Sale unless (a) the Issuer
or such Restricted Subsidiary, as the case may be, receives consideration at the
time of such Asset Sale at least equal to the fair market value (evidenced by a
resolution of the Board of Directors set forth in an Officers' Certificate
delivered to the Trustee) of the assets or Equity Interests issued or sold or
otherwise disposed of and (b) at least 75% of the consideration therefor
received by the Issuer or such Restricted Subsidiary is in the form of (i) cash
or Cash Equivalents or (ii) property or assets that are used or useful in a
Permitted Business, or the Capital Stock of any Person engaged in a Permitted
Business if, as a result of the acquisition by the Issuer or any Restricted
Subsidiary thereof, such Person becomes a Restricted Subsidiary; provided that
the amount of (x) any liabilities (as shown on the Issuer's or such Restricted
Subsidiary's most recent balance sheet), of the Issuer or any Restricted
Subsidiary (other than contingent liabilities and liabilities that are by their
terms subordinated to the Debentures or any guarantee thereof) that are assumed
by the transferee of any such assets pursuant to a customary novation agreement
that releases the Issuer or such Restricted Subsidiary from further liability,
(y) any securities, notes or other obligations received by the Issuer or any
such Restricted Subsidiary from such transferee that are contemporaneously
(subject to ordinary settlement periods) converted by the Issuer or such
Restricted Subsidiary into cash or Cash Equivalents (to the extent of the cash
or Cash Equivalents received), and (z) any Designated Noncash Consideration
received by the Issuer or any of its Restricted Subsidiaries in such Asset Sale
having an aggregate fair market value, taken together with all other Designated
Noncash Consideration received pursuant to this clause (z) that is at that time
outstanding, not to exceed 15% of Total Assets at the time of the receipt of
such Designated Noncash Consideration (with the fair market value of each item
of Designated Noncash Consideration being measured at the time received and
without giving effect to subsequent changes in value), shall be deemed to be
cash for purposes of this provision; and provided further that the 75%
limitation referred to in clause (b) above will not apply to any Asset Sale in
which the cash or Cash Equivalents portion of the consideration received
therefrom, determined in accordance with the foregoing proviso, is equal to or
greater than what the after-tax proceeds would have been had such Asset Sale
complied with the aforementioned 75% limitation.
 
     Within 365 days after the receipt of any Net Proceeds from an Asset Sale,
the Issuer or any such Restricted Subsidiary shall apply such Net Proceeds, at
its option, to (a) repay or purchase Pari Passu Indebtedness of the Issuer or
any Indebtedness of any Restricted Subsidiary, provided that, if the Issuer
shall so repay or purchase Pari Passu Indebtedness of the Issuer, it will
equally and ratably reduce Indebtedness under the Debentures if the Debentures
are then redeemable, or, if the Debentures may not then be redeemed, the Issuer
shall make an offer (in accordance with the procedures set forth below for an
Asset Sale Offer) to all Holders of Debentures to purchase at a purchase price
equal to 100% of the principal amount at maturity of the Debentures (or, in the
case of purchases of Debentures prior to June 1, 2003, at a purchase price equal
to 100% of the Accreted Value thereof), plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the date of purchase, the Debentures that
would otherwise be redeemed, or (b) an investment in property, the making of a
capital expenditure or the acquisition of assets that are used or useful in a
Permitted Business, or Capital Stock of any Person primarily engaged in a
Permitted Business if (i) as a result of the acquisition by the Issuer or any
Restricted Subsidiary thereof, such Person becomes a Restricted Subsidiary or
(ii) the Investment in such Capital Stock is permitted by clause (f) of the
definition of Permitted Investments. Pending the final application of any such
Net Proceeds, the Issuer may temporarily reduce Indebtedness or otherwise invest
such Net Proceeds in any manner that is not prohibited by the Indenture. Any Net
Proceeds from Asset Sales that are not applied or invested as provided in the
first sentence of this paragraph will be deemed to constitute "Excess Proceeds."
When the aggregate amount of Excess Proceeds exceeds $15.0 million, the Issuer
will be required to make an offer to all Holders of Debentures (an "Asset Sale
Offer") to purchase the maximum principal amount at maturity of Debentures that
may be purchased out of the Excess Proceeds, at an offer price in cash in an
amount equal to 100% of the principal amount at
 
                                       69
<PAGE>   71
 
maturity thereof, plus accrued and unpaid interest and Liquidated Damages, if
any, thereon to the date of purchase (or, in the case of repurchases of
Debentures prior to June 1, 2003, at a purchase price equal to 100% of the
Accreted Value, plus Liquidated Damages, if any, thereon as of the date of
repurchase), in accordance with the procedures set forth in the Indenture. To
the extent that any Excess Proceeds remain after consummation of an Asset Sale
Offer, the Issuer may use such Excess Proceeds for any purpose not otherwise
prohibited by the Indenture. If the aggregate principal amount at maturity or
Accreted Value (as applicable) of Debentures surrendered by Holders thereof in
connection with an Asset Sale Offer exceeds the amount of Excess Proceeds, the
Trustee shall select the Debentures to be purchased as set forth under
"-- Selection and Notice." Upon completion of such offer to purchase, the amount
of Excess Proceeds shall be reset at zero.
 
     The Issuer 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 the Debentures pursuant to an Asset Sale Offer. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of the Indenture relating to such Asset Sale Offer, the Issuer will
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations described in the Indenture by virtue
thereof.
 
     The New Credit Facility and the Senior Subordinated Notes restrict
Thermadyne LLC from paying any dividends or making any other distributions to
the Issuer. If the Issuer does not obtain the consent of the lenders under
agreements governing outstanding Indebtedness of its Subsidiaries, including
under the New Credit Facility and the Senior Subordinated Notes, to permit the
repurchase of the New Debentures or does not refinance such Indebtedness, the
Issuer will likely not have the financial resources to purchase New Debentures
and the Issuer's Subsidiaries will be restricted by the terms of such
Indebtedness from paying dividends to the Issuer or otherwise lending or
distributing funds to the Issuer for the purpose of such purchase. In any event,
there can be no assurance that the Issuer's Subsidiaries will have the resources
available to pay any such dividend or make any such distribution. The Issuer's
failure to make an Asset Sale Offer when required or to purchase tendered New
Debentures when tendered would constitute an Event of Default under the
Indenture. See "Risk Factors."
 
CERTAIN COVENANTS
 
  RESTRICTED PAYMENTS
 
     The Indenture provides that the Issuer will not, and will not permit any of
its Restricted Subsidiaries to, directly or indirectly, (a) declare or pay any
dividend or make any other payment or distribution on account of the Issuer's or
any of its Restricted Subsidiaries' Equity Interests (other than dividends or
distributions payable in Equity Interests (other than Disqualified Stock) of the
Issuer or dividends or distributions payable to the Issuer or any Wholly Owned
Restricted Subsidiary of the Issuer); (b) purchase, redeem or otherwise acquire
or retire for value any Equity Interests of the Issuer, any of its Restricted
Subsidiaries or any other Affiliate of the Issuer (other than any such Equity
Interests owned by the Issuer or any Restricted Subsidiary of the Issuer); (c)
make any principal payment on or with respect to, or purchase, redeem, defease
or otherwise acquire or retire for value, any Indebtedness of the Issuer (other
than the Debentures) that is pari passu or subordinated in right of payment to
the Debentures, except in accordance with the mandatory redemption or repayment
provisions set forth in the original documentation governing such Indebtedness
or in accordance with the covenant described under the caption entitled
"-- Repurchase at the Option of Holders -- Asset Sales" (but not pursuant to any
mandatory offer to repurchase upon the occurrence of any event); or (d) make any
Restricted Investment (all such payments and other actions set forth in clauses
(a) through (d) above being collectively referred to as "Restricted Payments"),
unless, at the time of and after giving effect to such Restricted Payment:
 
          (i) no Default or Event of Default shall have occurred and be
     continuing or would occur as a consequence thereof; and
 
          (ii) the Issuer would, immediately after giving pro forma effect
     thereto as if such Restricted Payment had been made at the beginning of the
     applicable four-quarter period, have been permitted to
 
                                       70
<PAGE>   72
 
     incur at least $1.00 of additional Indebtedness pursuant to the Fixed
     Charge Coverage Ratio test set forth in the first paragraph of the covenant
     described under caption "-- Incurrence of Indebtedness and Issuance of
     Preferred Stock"; and
 
          (iii) such Restricted Payment, together with the aggregate amount of
     all other Restricted Payments made by the Issuer and its Restricted
     Subsidiaries after the date of the Indenture (excluding Restricted Payments
     permitted by clauses (a) (to the extent that the declaration of any
     dividend referred to therein reduces amounts available for Restricted
     Payments pursuant to this clause (iii)), (b), (c), (e) through (g), (j),
     and (m) through (p) of the next succeeding paragraph), is less than the
     sum, without duplication, of (A) 50% of the Consolidated Net Income of the
     Issuer for the period (taken as one accounting period) commencing July 1,
     1998 to the end of the Issuer's most recently ended fiscal quarter for
     which internal financial statements are available at the time of such
     Restricted Payment (or, if such Consolidated Net Income for such period is
     a deficit, less 100% of such deficit), plus (B) 100% of the Qualified
     Proceeds received by the Issuer on or after the date of the Indenture from
     contributions to the Issuer's capital or from the issue or sale on or after
     the date of the Indenture of Equity Interests of the Issuer or of
     Disqualified Stock or convertible debt securities of the Issuer to the
     extent that they have been converted into such Equity Interests (other than
     Equity Interests, Disqualified Stock or convertible debt securities sold to
     a Subsidiary of the Issuer and other than Disqualified Stock or convertible
     debt securities that have been converted into Disqualified Stock), plus (C)
     the amount equal to the net reduction in Investments in Persons after the
     date of the Indenture who are not Restricted Subsidiaries (other than
     Permitted Investments) resulting from (x) Qualified Proceeds received as a
     dividend, repayment of a loan or advance or other transfer of assets
     (valued at the fair market value thereof) to the Issuer or any Restricted
     Subsidiary from such Persons, (y) Qualified Proceeds received upon the sale
     or liquidation of such Investment and (z) the redesignation of Unrestricted
     Subsidiaries (other than any Unrestricted Subsidiary designated as such
     pursuant to clause (n) of the following paragraph) whose assets are used or
     useful in, or which is engaged in, one or more Permitted Business as
     Restricted Subsidiaries (valued (proportionate to the Issuer's equity
     interest in such Subsidiary) at the fair market value of the net assets of
     such Subsidiary at the time of such redesignation).
 
     The foregoing provisions will not prohibit:
 
     (a) the payment of any dividend within 60 days after the date of
declaration thereof, if at said date of declaration such payment would have
complied with the provisions of the Indenture;
 
     (b)(i) the redemption, repurchase, retirement, defeasance or other
acquisition of any Pari Passu Indebtedness, Subordinated Indebtedness or Equity
Interests of the Issuer (the "Retired Capital Stock") in exchange for, or out of
the net cash proceeds of the substantially concurrent sale (other than to a
Subsidiary of the Issuer) of, other Equity Interests of the Issuer (other than
any Disqualified Stock) (the "Refunding Capital Stock"), provided that the
amount of any such net cash proceeds that are utilized for any such redemption,
repurchase, retirement, defeasance or other acquisition shall be excluded from
clause (iii)(B) of the preceding paragraph and (ii) if immediately prior to the
retirement of Retired Capital Stock, the declaration and payment of dividends
thereon was permitted under clause (f) of this paragraph, the declaration and
payment of dividends on the Refunding Capital Stock in an aggregate amount per
year no greater than the aggregate amount of dividends per annum that was
declarable and payable on such Retired Capital Stock immediately prior to such
retirement; provided that, at the time of the declaration of any such dividends,
no Default or Event of Default shall have occurred and be continuing or would
occur as a consequence thereof;
 
     (c) the defeasance, redemption, repurchase, retirement or other acquisition
of Pari Passu Indebtedness or Subordinated Indebtedness with the net cash
proceeds from an incurrence of, or in exchange for, Permitted Refinancing
Indebtedness;
 
     (d) the repurchase, redemption or other acquisition or retirement for value
of any Equity Interests of the Issuer or Thermadyne LLC held by any member of
Thermadyne LLC's or the Issuer's (or any of its Restricted Subsidiaries')
management pursuant to any management equity subscription agreement or stock

option agreement, provided that the aggregate price paid for all such
repurchased, redeemed, acquired or retired Equity Interests shall not exceed (x)
$7.5 million in any calendar year (with unused amounts in any calendar year
being carried over to succeeding calendar years subject to a maximum (without
giving effect to the following clause (y)) of $15.0 million in any calendar
year), plus (y) the aggregate cash proceeds received by the Issuer during such
calendar year from any reissuance of Equity Interests by the Issuer or
Thermadyne LLC to members of management of the Issuer and its Restricted
Subsidiaries and (ii) no Default or Event of Default shall have occurred and be
continuing immediately after such transaction;
 
     (e) payments and transactions in connection with the Recapitalization, the
New Credit Facility (including commitment, syndication and arrangement fees
payable thereunder) and the application of the proceeds thereof, and the payment
of fees and expenses with respect thereto;
 
     (f) the declaration and payment of dividends to holders of any class or
series of preferred stock (other than Disqualified Stock), provided that, at the
time of such issuance, after giving effect to such issuance on a pro forma
basis, the Fixed Charge Coverage Ratio for the Issuer for the most recently
ended four full fiscal quarters for which internal financial statements are
available immediately preceding the date of such issuance would have been no
less than 1.5 to 1;
 
     (g) the payment of dividends or distributions by a Restricted Subsidiary on
any class of common stock or membership interests of such Restricted Subsidiary
if (i) such dividend or distribution is paid pro rata to all holders of such
class of common stock or membership interests and (ii) at least 51% of such

more of its Restricted Subsidiaries;
 
     (i) any other Restricted Investment made in a Permitted Business which,

after giving effect to all subsequent reductions in the amount of any Restricted
Investment made pursuant to this clause (i), either as a result of (A) the
repayment or disposition thereof for cash or (B) the redesignation of an
Unrestricted Subsidiary as a Restricted Subsidiary (valued proportionate to the
Issuer's equity interest in such Subsidiary at the time of such redesignation)
at the fair market value of the net assets of such Subsidiary at the time of
such redesignation), in the case of clause (A) and (B), not to exceed the amount
of such Restricted Investment previously made pursuant to this clause (i);
provided that no Default or Event of Default shall have occurred and be
continuing immediately after making such Restricted Investment;
 
     (j) the declaration and payment of dividends to holders of any class or

     (m) any other Restricted Payment which, together with all other Restricted
Payments made pursuant to this clause (m) since the date of the Indenture, does
not exceed $25.0 million (in each case, after giving effect to all subsequent
reductions in the amount of any Restricted Investment made pursuant to this
clause (m) either as a result of (i) the repayment or disposition thereof for
cash or (ii) the redesignation of an Unrestricted Subsidiary as a Restricted

the amount of cash and Cash Equivalents received by such Restricted Subsidiary
from the issue or sale thereof and (ii) any accrued dividends thereon the
payment of which would be permitted pursuant to clause (j) above;
 
     (p) distributions or payments of Receivables Fees; and
 
     (q) the purchase, redemption or other acquisition or retirement for value
of rights issued pursuant to the Issuer's Rights Plan as in effect on the date
of the Indenture.
 
     The Board of Directors may designate any Restricted Subsidiary (other than
Thermadyne LLC and Thermadyne Capital) to be an Unrestricted Subsidiary if such
designation would not cause a Default. For purposes of making such designation,
all outstanding Investments by the Issuer and its Restricted Subsidiaries
(except to the extent repaid in cash) in the Subsidiary so designated will be
deemed to be Restricted Payments at the time of such designation and will reduce
the amount available for Restricted Payments under the first paragraph of this
covenant. All such outstanding Investments will be deemed to constitute
Restricted Investments in an amount equal to the greater of (i) the net book
value of such Investments at the time of such designation and (ii) the fair
market value of such Investments at the time of such designation. Such
designation will only be permitted if such Restricted Investment would be
permitted at such time and if such Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary.
 
     The amount of (i) all Restricted Payments (other than cash) shall be the
fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Issuer or such Restricted
Subsidiary, as the case may be, pursuant to the Restricted Payment and (ii)
Qualified Proceeds (other than cash) shall be the fair market value on the date
of receipt thereof by the Issuer of such Qualified Proceeds. The fair market
value of any non-cash Restricted Payment shall be determined by the Board of
Directors whose resolution with respect thereto shall be delivered to the
Trustee. Not later than the date of making any Restricted Payment, the Issuer
shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the
calculations required by the covenant "Restricted Payments" were computed.
 
  INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK
 
     The Indenture provides that (a) the Issuer will not, and will not permit
any of its Restricted Subsidiaries to, directly or indirectly, create, incur,
issue, assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness (including Acquired Indebtedness), (b) the Issuer will not, and
will not permit any of its Restricted Subsidiaries to, issue any shares of
Disqualified Stock and (c) the Issuer will not permit any of its Restricted
Subsidiaries to issue any shares of preferred stock; provided that the Issuer or
any Restricted Subsidiary may incur Indebtedness (including Acquired
Indebtedness) or issue shares of Disqualified Stock if the Fixed Charge Coverage
Ratio for the Issuer's most recently ended four full fiscal quarters for which
internal financial statements are available immediately preceding the date on
which such additional Indebtedness is incurred or such
 
                                       73
<PAGE>   75
 
Disqualified Stock is issued would have been at least 1.5 to 1, determined on a
consolidated pro forma basis (including a pro forma application of the net
proceeds therefrom), as if the additional Indebtedness had been incurred, or the
Disqualified Stock had been issued, as the case may be, at the beginning of such
four-quarter period.
 
     The Indenture also provides that the Issuer will not incur any Indebtedness
that is contractually subordinated in right of payment to any other Indebtedness
of the Issuer unless such Indebtedness is also contractually subordinated in
right of payment to the Debentures on substantially identical terms; provided
that no Indebtedness of the Issuer shall be deemed to be contractually
subordinated in right of payment to any other Indebtedness of the Issuer solely
by virtue of being unsecured.
 
     The provisions of the first paragraph of this covenant will not apply to
the incurrence of any of the following items of Indebtedness (collectively,
"Permitted Indebtedness"):
 
          (i) the incurrence by the Issuer and its Restricted Subsidiaries of
     Indebtedness under the New Credit Facility; provided that the aggregate
     principal amount of all Indebtedness (with letters of credit being deemed
     to have a principal amount equal to the maximum potential liability of the
     Issuer and such Restricted Subsidiaries thereunder) then classified as
     having been incurred in reliance upon this clause (i) that remains
     outstanding under the New Credit Facility after giving effect to such
     incurrence does not exceed an amount equal to $430.0 million;
 
          (ii) the incurrence by the Issuer and its Restricted Subsidiaries of
     Existing Indebtedness;
 
          (iii) the incurrence by (A) the Issuer and the Issuer's Restricted
     Subsidiaries of Indebtedness represented by the Debentures and the
     Indenture and (B) Thermadyne LLC and Thermadyne Capital of Indebtedness
     represented by the Senior Subordinated Notes and the Subordinated Note
     Indenture;
 
          (iv) the incurrence by the Issuer or any of its Restricted
     Subsidiaries of Indebtedness represented by Capital Expenditure
     Indebtedness, Capital Lease Obligations or purchase money obligations, in
     each case, incurred for the purpose of financing all or any part of the
     purchase price or cost of construction or improvement of property, plant or
     equipment used in the business of the Issuer or such Restricted Subsidiary,
     in an aggregate principal amount (or accreted value, as applicable) not to
     exceed $40.0 million outstanding after giving effect to such incurrence;
 
          (v) Indebtedness arising from agreements of the Issuer or any
     Restricted Subsidiary providing for indemnification, adjustment of purchase
     price or similar obligations, in each case, incurred or assumed in
     connection with the disposition of any business, assets or a Subsidiary,
     other than guarantees of Indebtedness incurred by any Person acquiring all
     or any portion of such business, assets or Restricted Subsidiary for the
     purpose of financing such acquisition; provided that (A) such Indebtedness
     is not reflected on the balance sheet of the Issuer or any Restricted
     Subsidiary (contingent obligations referred to in a footnote or footnotes
     to financial statements and not otherwise reflected on the balance sheet
     will not be deemed to be reflected on such balance sheet for purposes of
     this clause (A)) and (B) the maximum assumable liability in respect of such
     Indebtedness shall at no time exceed the gross proceeds including non-cash
     proceeds (the fair market value of such non-cash proceeds being measured at
     the time received and without giving effect to any subsequent changes in
     value) actually received by the Issuer and/or such Restricted Subsidiary in
     connection with such disposition;
 
          (vi) the incurrence by the Issuer or any of its Restricted
     Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
     net proceeds of which are used to refund, refinance or replace Indebtedness
     (other than intercompany Indebtedness) that was permitted by the Indenture
     to be incurred;
 
          (vii) the incurrence by the Issuer or any of its Restricted
     Subsidiaries of intercompany Indebtedness between or among the Issuer
     and/or any of its Restricted Subsidiaries; provided that (i) if the Issuer
     is the obligor on such Indebtedness, such Indebtedness is expressly
     subordinated to the prior payment in full in cash of all Obligations with
     respect to the Debentures and (ii)(A) any subsequent issuance or transfer
     of Equity Interests that results in any such Indebtedness being held by a
     Person other than the
 
                                       74
<PAGE>   76
 
     Issuer or a Restricted Subsidiary thereof and (B) any sale or other
     transfer of any such Indebtedness to a Person that is not either the Issuer
     or a Restricted Subsidiary thereof shall be deemed, in each case, to
     constitute an incurrence of such Indebtedness by the Issuer or such
     Restricted Subsidiary, as the case may be, that was not permitted by this
     clause (vii);
 
          (viii) the incurrence by the Issuer or any of its Restricted
     Subsidiaries of Hedging Obligations that are incurred for the purpose of
     fixing or hedging (A) interest rate risk with respect to any floating rate
     Indebtedness that is permitted by the terms of this Indenture to be
     outstanding and (B) exchange rate risk with respect to agreements or
     Indebtedness of such Person payable denominated in a currency other than
     U.S. dollars, provided that such agreements do not increase the
     Indebtedness of the obligor outstanding at any time other than as a result
     of fluctuations in foreign currency exchange rates or interest rates or by
     reason of fees, indemnities and compensation payable thereunder;
 
          (ix) the guarantee by the Issuer or any of its Restricted Subsidiaries
     of Indebtedness of the Issuer or a Restricted Subsidiary of the Issuer that
     was permitted to be incurred by another provision of this covenant;
 
          (x) the incurrence by the Issuer or any of its Restricted Subsidiaries
     of Acquired Indebtedness in an aggregate principal amount (or accreted
     value, as applicable) not to exceed $25.0 million outstanding after giving
     effect to such incurrence;
 
          (xi) obligations in respect of performance and surety bonds and
     completion guarantees provided by the Issuer or any Restricted Subsidiary
     in the ordinary course of business; and
 
          (xii) the incurrence by the Issuer or any of its Restricted
     Subsidiaries of additional Indebtedness in an aggregate principal amount
     (or accreted value, as applicable) outstanding after giving effect to such
     incurrence, including all Permitted Refinancing Indebtedness incurred to
     refund, refinance or replace any Indebtedness incurred pursuant to this
     clause (xii), not to exceed $50.0 million.
 
     For purposes of determining compliance with this covenant, in the event
that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Indebtedness described in clauses (i) through (xii)
above or is entitled to be incurred pursuant to the first paragraph of this
covenant, the Issuer shall, in its sole discretion, classify such item of
Indebtedness in any manner that complies with this covenant and such item of
Indebtedness will be treated as having been incurred pursuant to only one of
such clauses or pursuant to the first paragraph hereof. In addition, the Issuer
may, at any time, change the classification of an item of Indebtedness (or any
portion thereof) to any other clause or to the first paragraph hereof, provided
that the Issuer would be permitted to incur such item of Indebtedness (or such
portion thereof) pursuant to such other clause or the first paragraph hereof, as
the case may be, at such time of reclassification. Accrual of interest,
accretion or amortization of original issue discount will not be deemed to be an
incurrence of Indebtedness for purposes of this covenant.
 
     All Indebtedness under the New Credit Facility outstanding on the date on
which Debentures are first issued and authenticated under the Indenture shall be
deemed to have been incurred on such date in reliance on the first paragraph of
the covenant described under the caption "-- Certain Covenants -- Incurrence of
Indebtedness and Issuance of Preferred Stock." As a result, the Issuer will be
permitted to incur significant additional secured indebtedness under clause (i)
of the definition of "Permitted Indebtedness." See "Risk Factors."
 
  LIENS
 
     The Indenture provides that the Issuer will not, and will not permit any of
its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or
suffer to exist any Lien, other than a Permitted Lien, that secures obligations
under any Pari Passu Indebtedness or Subordinated Indebtedness of the Issuer on
any asset or property now owned or hereafter acquired by the Issuer or any of
its Restricted Subsidiaries, or any income or profits therefrom or assign or
convey any right to receive income therefrom, unless the Debentures
 
                                       75
<PAGE>   77
 
are equally and ratably secured with the obligations so secured until such time
as such obligations are no longer secured by a Lien.
 
  DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED SUBSIDIARIES
 
     The Indenture provides that the Issuer will not, and will not permit any of
its Restricted Subsidiaries to, directly or indirectly, create or otherwise
cause or suffer to exist or become effective any encumbrance or restriction on
the ability of any Restricted Subsidiary to (a)(i) pay dividends or make any
other distributions to the Issuer or any of its Restricted Subsidiaries (A) on
its Capital Stock or (B) with respect to any other interest or participation in,
or measured by, its profits, or (ii) pay any Indebtedness owed to the Issuer or
any of its Restricted Subsidiaries, (b) make loans or advances to the Issuer or
any of its Restricted Subsidiaries or (c) transfer any of its properties or
assets to the Issuer or any of its Restricted Subsidiaries. However, the
foregoing restrictions will not apply to encumbrances or restrictions existing
under or by reason of (a) Existing Indebtedness as in effect on the date of the
Indenture, (b) the terms of any Indebtedness permitted by the Indenture to be
incurred by any Restricted Subsidiary of the Issuer, (c) the Indenture and the
Debentures, (d) applicable law and any applicable rule, regulation or order, (e)
any agreement or instrument of a Person acquired by the Issuer or any of its
Restricted Subsidiaries as in effect at the time of such acquisition (except to
the extent created in contemplation of such acquisition), which encumbrance or
restriction is not applicable to any Person, or the properties or assets of any
Person, other than the Person, or the property or assets of the Person, so
acquired, provided that, in the case of Indebtedness, such Indebtedness was
permitted by the terms of the Indenture to be incurred, (f) customary
non-assignment provisions in leases entered into in the ordinary course of
business and consistent with past practices, (g) purchase money obligations for
property acquired in the ordinary course of business that impose restrictions of
the nature described in clause (e) above on the property so acquired, (h)
contracts for the sale of assets, including, without limitation, customary
restrictions with respect to a Subsidiary pursuant to an agreement that has been
entered into for the sale or disposition of all or substantially all of the
Capital Stock or assets of such Subsidiary, (i) Permitted Refinancing
Indebtedness, provided that the restrictions contained in the agreements
governing such Permitted Refinancing Indebtedness are, in the good faith
judgment of the Issuer's Board of Directors, not materially less favorable,
taken as a whole, to the Holders of the Debentures than those contained in the
agreements governing the Indebtedness being refinanced, (j) secured Indebtedness
otherwise permitted to be incurred pursuant to the covenants described under
"--Incurrence of Indebtedness and Issuance of Preferred Stock" and "--Liens"
that limit the right of the debtor to dispose of the assets securing such
Indebtedness, (k) restrictions on cash or other deposits or net worth imposed by
customers under contracts entered into in the ordinary course of business, (l)
other Indebtedness or Disqualified Stock of Restricted Subsidiaries permitted to
be incurred subsequent to the Issuance Date pursuant to the provisions of the
covenant described under "--Incurrence of Indebtedness and Issuance of Preferred
Stock", (m) customary provisions in joint venture agreements and other similar
agreements entered into in the ordinary course of business, and (n) restrictions
created in connection with any Receivables Facility that, in the good faith
determination of the Board of Directors of the Issuer, are necessary or
advisable to effect such Receivables Facility.
 
     The New Credit Facility and the Senior Subordinated Notes restrict
Thermadyne LLC from paying any dividends or making any other distributions to
the Issuer. The existence of such restrictions could have an adverse effect on
the Issuer's ability to pay interest and principal on the Debentures. See "Risk
Factors."
 
  MERGER, CONSOLIDATION, OR SALE OF ASSETS
 
     The Indenture provides that the Issuer may not consolidate or merge with or
into (whether or not the Issuer is the surviving corporation), or sell, assign,
transfer, convey or otherwise dispose of all or substantially all of its
properties or assets in one or more related transactions, to another Person
unless (a) the Issuer is the surviving corporation or the Person formed by or
surviving any such consolidation or merger (if other than the Issuer) or to
which such sale, assignment, transfer, conveyance or other disposition shall
have been made is a corporation organized or existing under the laws of the
United States, any state thereof or the District of Columbia, (b) the Person
formed by or surviving any such consolidation or merger (if other than the
Issuer) or the Person to which such sale, assignment, transfer, conveyance or
other disposition shall have been made
 
                                       76
<PAGE>   78
 
assumes all the obligations of the Issuer under the Registration Rights
Agreement, the Debentures and the Indenture pursuant to a supplemental indenture
in a form reasonably satisfactory to the Trustee, (c) immediately after such
transaction no Default or Event of Default exists and (d) the Issuer or the
Person formed by or surviving any such consolidation or merger (if other than
the Issuer), or to which such sale, assignment, transfer, conveyance or other
disposition shall have been made (i) will, at the time of such transaction and
after giving pro forma effect thereto as if such transaction had occurred at the
beginning of the applicable four-quarter period, be permitted to incur at least
$1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
test set forth in the first paragraph of the covenant described under the
caption "-- Incurrence of Indebtedness and Issuance of Preferred Stock" or (ii)
would (together with its Restricted Subsidiaries) have a higher Fixed Charge
Coverage Ratio immediately after such transaction (after giving pro forma effect
thereto as if such transaction had occurred at the beginning of the applicable
four-quarter period) than the Fixed Charge Coverage Ratio of the Issuer and its
Restricted Subsidiaries immediately prior to such transaction. The foregoing
clause (d) will not prohibit (a) a merger between the Issuer and an Affiliate of
the Issuer created for the purpose of holding the Capital Stock of the Issuer,
(b) a merger between the Issuer and a Wholly Owned Restricted Subsidiary or (c)
a merger between the Issuer and an Affiliate incorporated solely for the purpose
of reincorporating the Issuer in another State of the United States so long as,
in each case, the amount of Indebtedness of the Issuer and its Restricted
Subsidiaries is not increased thereby. The Indenture provides that the Issuer
shall not lease all or substantially all of its assets to any Person.
 
  TRANSACTIONS WITH AFFILIATES
 
     The Indenture provides that the Issuer will not, and will not permit any of
its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate of the Issuer (each of the foregoing, an "Affiliate
Transaction"), unless (a) such Affiliate Transaction is on terms that are no
less favorable to the Issuer or such Restricted Subsidiary than those that would
have been obtained in a comparable transaction by the Issuer or such Restricted
Subsidiary with an unrelated Person and (b) the Issuer delivers to the Trustee,
with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $7.5 million, either
(i) a resolution of the Board of Directors set forth in an Officers' Certificate
certifying that such Affiliate Transaction complies with clause (a) above and
that such Affiliate Transaction has been approved by a majority of the
disinterested members of the Board of Directors or (ii) an opinion as to the
fairness to the Holders of such Affiliate Transaction from a financial point of
view issued by an accounting, appraisal or investment banking firm of national
standing.
 
     Notwithstanding the foregoing, the following items shall not be deemed to
be Affiliate Transactions: (a) customary directors' fees, indemnification or
similar arrangements or any employment agreement or other compensation plan or
arrangement entered into by the Issuer or any of its Restricted Subsidiaries in
the ordinary course of business (including ordinary course loans to employees
not to exceed (i) $5.0 million outstanding in the aggregate at any time and (ii)
$2.0 million to any one employee) and consistent with the past practice of the
Issuer or such Restricted Subsidiary; (b) transactions between or among the
Issuer and/or its Restricted Subsidiaries; (c) payments of customary fees by the
Issuer or any of its Restricted Subsidiaries to DLJMB and its Affiliates made
for any financial advisory, financing, underwriting or placement services or in
respect of other investment banking activities, including, without limitation,
in connection with acquisitions or divestitures which are approved by a majority
of the Board of Directors in good faith; (d) any agreement as in effect on the
date of the Indenture or any amendment thereto (so long as such amendment is not
disadvantageous to the Holders of the Debentures in any material respect) or any
transaction contemplated thereby; (e) payments and transactions in connection
with the Merger, the New Credit Facility (including commitment, syndication and
arrangement fees payable thereunder) and the Offerings (including underwriting
discounts and commissions in connection therewith) and the application of the
proceeds thereof, and the payment of the fees and expenses with respect thereto;
(f) Restricted Payments that are permitted by the provisions of the Indenture
described under the caption "--Restricted Payments"; (g) sales of accounts
receivable, or participations therein, in connection with any Receivables
Facility; and (h) transactions pursuant to the Management Loans.

<PAGE>   79
 
  SALE AND LEASEBACK TRANSACTIONS
 
     The Indenture provides that the Issuer will not, and will not permit any of
its Restricted Subsidiaries to, enter into any sale and leaseback transaction;
provided that the Issuer or any Restricted Subsidiary may enter into a sale and
leaseback transaction if (a) the Issuer or such Restricted Subsidiary, as the
case may be, could have (i) incurred Indebtedness in an amount equal to the
Attributable Indebtedness relating to such sale and leaseback transaction
pursuant to the Fixed Charge Coverage Ratio test set forth in the first
paragraph of the covenant described under the caption "-- Incurrence of
Indebtedness and Issuance of Preferred Stock" and (ii) incurred a Lien to secure
such Indebtedness pursuant to the covenant described under the caption
"-- Liens," (b) the gross cash proceeds of such sale and leaseback transaction
are at least equal to the fair market value (as determined in good faith by the
Board of Directors and set forth in an Officers' Certificate delivered to the
Trustee) of the property that is the subject of such sale and leaseback
transaction and (c) the transfer of assets in such sale and leaseback
transaction is permitted by, and the Issuer applies the proceeds of such
transaction in compliance with, the covenant described under the caption
"Repurchase at the Option of Holders -- Asset Sales."
 
  ACCOUNTS RECEIVABLE FACILITY
 
     The Indenture provides that no Accounts Receivable Subsidiary will incur
any Indebtedness if immediately after giving effect to such incurrence the
aggregate outstanding Indebtedness of all Accounts Receivable Subsidiaries
(excluding any Indebtedness owed to the Issuer or any Restricted Subsidiary)
would exceed $60.0 million.
 
  REPORTS
 
     The Indenture provides that, whether or not required by the rules and
regulations of the Securities and Exchange Commission (the "Commission"), so
long as any Debentures are outstanding, the Issuer will furnish to the Holders
of Debentures (a) 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 Issuer were required to file such Forms, including a "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and,
with respect to the annual information only, a report thereon by the Issuer's
certified independent accountants and (b) all current reports that would be
required to be filed with the Commission on Form 8-K if the Issuer were required
to file such reports, in each case, within the time periods specified in the
Commission's rules and regulations. In addition, following the consummation of
the Exchange Offer, whether or not required by the rules and regulations of the
Commission, the Issuer will file a copy of all such information and reports with
the Commission for public availability within the time periods specified in the
Commission's rules and regulations (unless the Commission will not accept such a
filing) and make such information available to securities analysts and
prospective investors upon request. In addition, the Issuer has agreed that, for
so long as any Debentures remain outstanding, it will furnish to the Holders and
to securities analysts and prospective investors, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act.
 
EVENTS OF DEFAULT AND REMEDIES
 
     The Indenture provides that each of the following constitutes an Event of
Default: (a) default for 30 days in the payment when due of interest on, or
Liquidated Damages with respect to, the Debentures; (b) default in payment when
due of the principal of or premium, if any, on the Debentures at maturity, upon
redemption or otherwise; (c) failure by the Issuer or any of its Restricted
Subsidiaries for 30 days after receipt of notice from the Trustee or Holders of
at least 25% in principal amount at maturity of the Debentures then outstanding
to comply with the provisions described under the captions "Repurchase at the
Option of Holders -- Change of Control," "-- Asset Sales," "Certain
Covenants -- Restricted Payments," "-- Incurrence of Indebtedness and Issuance
of Preferred Stock" or "Merger, Consolidation or Sale of Assets"; (d) failure by
the Issuer for 60 days after notice from the Trustee or the Holders of at least
25% in principal amount at maturity of the Debentures then outstanding to comply
with any of its other agreements in the Indenture or the Debentures; (e) default
under any mortgage, indenture or instrument under which there may
 
                                       78
<PAGE>   80
 
be issued or by which there may be secured or evidenced any Indebtedness for
money borrowed by the Issuer or any of its Restricted Subsidiaries (or the
payment of which is guaranteed by the Issuer or any of its Restricted
Subsidiaries), whether such Indebtedness or guarantee now exists, or is created
after the date of the Indenture, which default (i) is caused by a failure to pay
Indebtedness at its stated final maturity (after giving effect to any applicable
grace period provided in such Indebtedness) (a "Payment Default") or (ii)
results in the acceleration of such Indebtedness prior to its stated final
maturity and, in each case, the principal amount of any such Indebtedness,
together with the principal amount of any other such Indebtedness under which
there has been a Payment Default or the maturity of which has been so
accelerated, aggregates $10.0 million or more; (f) failure by the Issuer or any
of its Restricted Subsidiaries to pay final judgments aggregating in excess of
$10.0 million (net of any amounts with respect to which a reputable and
creditworthy insurance Company has acknowledged liability in writing), which
judgments are not paid, discharged or stayed for a period of 60 days; and (g)
certain events of bankruptcy or insolvency with respect to the Issuer or any of
its Restricted Subsidiaries that is a Significant Subsidiary.
 
     If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount at maturity of the then outstanding
Debentures may declare all the Debentures to be due and payable immediately;
provided that, so long as any Indebtedness permitted to be incurred pursuant to
the New Credit Facility shall be outstanding, such acceleration shall not be
effective until the earlier of (a) an acceleration of any such Indebtedness
under the New Credit Facility or (b) five business days after receipt by the
Issuer and the administrative agent under the New Credit Facility of written
notice of such acceleration. Notwithstanding the foregoing, in the case of an
Event of Default arising from certain events of bankruptcy or insolvency with
respect to the Issuer or any Significant Subsidiary, all outstanding Debentures
will become due and payable without further action or notice. Upon any
acceleration of maturity of the Debentures, all principal of and accrued
interest on (if on or after June 1, 2003) or Accreted Value of (if prior to June
1, 2003) the Debentures shall be due and payable immediately. Holders of the
Debentures may not enforce the Indenture or the Debentures except as provided in
the Indenture. In the event of a declaration of acceleration of the Debentures
because an Event of Default has occurred and is continuing as a result of the
acceleration of any Indebtedness described in clause (e) of the preceding
paragraph, the declaration of acceleration of the Debentures shall be
automatically annulled if the holders of any Indebtedness described in clause
(e) have rescinded the declaration of acceleration in respect of such
Indebtedness within 30 days of the date of such declaration and if (i) the
annulment of the acceleration of the Debentures would not conflict with any
judgment or decree of a court of competent jurisdiction and (ii) all existing
Events of Default, except non-payment of principal or interest on the Debentures
that became due solely because of the acceleration of the Debentures, have been
cured or waived.
 
     Subject to certain limitations, Holders of a majority in principal amount
at maturity of the then outstanding Debentures may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the
Debentures notice of any continuing Default or Event of Default (except a
Default or Event of Default relating to the payment of principal or interest) if
it determines that withholding notice is in their interest.
 
     The Holders of a majority in aggregate principal amount at maturity of the
Debentures then outstanding by notice to the Trustee may on behalf of the
Holders of all of the Debentures waive any existing Default or Event of Default
and its consequences under the Indenture except a continuing Default or Event of
Default in the payment of interest on, or the principal of, the Debentures.
 
     The Issuer is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Issuer is required upon
becoming aware of any Default or Event of Default to deliver to the Trustee a
statement specifying such Default or Event of Default.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS
 
     No director, officer, employee, incorporator or stockholder of the Issuer,
as such, shall have any liability for any obligations of the Issuer under the
Debentures or the Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of Debentures by
accepting a Debenture
 
                                       79
<PAGE>   81
 
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Debentures. Such waiver may not be effective
to waive liabilities under the federal securities laws, and it is the view of
the Commission that such a waiver is against public policy.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
     The Issuer may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Debentures ("Legal
Defeasance") except for (a) the rights of Holders of outstanding Debentures to
receive payments in respect of the principal of, premium, if any, and interest
and Liquidated Damages, if any, on such Debentures when such payments are due
from the trust referred to below, (b) the Issuer's obligations with respect to
the Debentures concerning issuing temporary Debentures, registration of
Debentures, mutilated, destroyed, lost or stolen Debentures and the maintenance
of an office or agency for payment and money for security payments held in
trust, (c) the rights, powers, trusts, duties and immunities of the Trustee, and
the Issuer's obligations in connection therewith and (d) the Legal Defeasance
provisions of the Indenture. In addition, the Issuer may, at its option and at
any time, elect to have the obligations of the Issuer released with respect to
certain covenants that are described in the Indenture ("Covenant Defeasance")
and thereafter any omission to comply with such obligations shall not constitute
a Default or Event of Default with respect to the Debentures. In the event
Covenant Defeasance occurs, certain events (not including non-payment,
bankruptcy, receivership, rehabilitation and insolvency events) described under
"Events of Default and Remedies" will no longer constitute an Event of Default
with respect to the Debentures.
 
     In order to exercise either Legal Defeasance or Covenant Defeasance, (a)
the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit
of the Holders of the Debentures, cash in U.S. dollars, non-callable Government
Securities, or a combination thereof, in such amounts as will be sufficient, in
the opinion of a nationally recognized firm of independent public accountants,
to pay the principal of, premium, if any, and interest and Liquidated Damages,
if any, on the outstanding Debentures on the stated maturity or on the
applicable redemption date, as the case may be, and the Issuer must specify
whether the Debentures are being defeased to maturity or to a particular
redemption date, (b) in the case of Legal Defeasance, the Issuer shall have
delivered to the Trustee an opinion of counsel in the United States reasonably
acceptable to the Trustee confirming that (i) the Issuer has received from, or
there has been published by, the Internal Revenue Service a ruling or (ii) since
the date of the Indenture, there has been a change in the applicable federal
income tax law, in either case to the effect that, and based thereon such
opinion of counsel shall confirm that, subject to customary assumptions and
exclusions, the Holders of the outstanding Debentures will not recognize income,
gain or loss for federal income tax purposes as a result of such Legal
Defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Legal
Defeasance had not occurred, (c) in the case of Covenant Defeasance, the Issuer
shall have delivered to the Trustee an opinion of counsel in the United States
reasonably acceptable to the Trustee confirming that, subject to customary
assumptions and exclusions, the Holders of the outstanding Debentures will not
recognize income, gain or loss for federal income tax purposes as a result of
such Covenant Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such Covenant Defeasance had not occurred, (d) no Default or Event of Default
shall have occurred and be continuing on the date of such deposit (other than a
Default or Event of Default resulting from the borrowing of funds to be applied
to such deposit) or, insofar as Events of Default from bankruptcy or insolvency
events are concerned, at any time in the period ending on the 123rd day after
the date of deposit, (e) such Legal Defeasance or Covenant Defeasance will not
result in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than the Indenture) to which the Issuer or any of
its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is
bound, (f) the Issuer must have delivered to the Trustee an opinion of counsel
to the effect that, subject to customary assumptions and exclusions, after the
123rd day following the deposit, the trust funds will not be subject to the
effect of Section 547 of the United States Bankruptcy Code or any analogous New
York State law provision or any other applicable federal or New York bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights
generally, (g) the Issuer must deliver to the Trustee an Officers' Certificate
stating that the deposit was not made by the Issuer with the intent of
preferring the Holders of Debentures over the other
 
                                       80
<PAGE>   82
 
creditors of the Issuer with the intent of defeating, hindering, delaying or
defrauding creditors of the Issuer or others, and (h) the Issuer must deliver to
the Trustee an Officers' Certificate and an opinion of counsel (which opinion
may be subject to customary assumptions and exclusions), each stating that all
conditions precedent provided for relating to the Legal Defeasance or the
Covenant Defeasance have been complied with.
 
TRANSFER AND EXCHANGE
 
     A Holder may transfer or exchange New Debentures in accordance with the
Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Issuer may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Issuer is not required to transfer or exchange
any New Debenture selected for redemption. Also, the Issuer is not required to
transfer or exchange any New Debenture for a period of 15 days before a
selection of New Debentures to be redeemed. The registered Holder of a New
Debenture will be treated as the owner of it for all purposes.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
     Except as provided in the next two succeeding paragraphs, the Indenture and
the Debentures may be amended or supplemented with the consent of the Holders of
at least a majority in principal amount at maturity of the Debentures then
outstanding (including, without limitation, consents obtained in connection with
a purchase of, or tender offer or exchange offer for, Debentures), and any
existing default or compliance with any provision of the Indenture or the
Debentures may be waived with the consent of the Holders of a majority in
principal amount at maturity of the then outstanding Debentures (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, Debentures).
 
     Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any Debentures held by a non-consenting Holder) (a) reduce the
principal amount at maturity of Debentures whose Holders must consent to an
amendment, supplement or waiver, (b) reduce the principal of or change the fixed
maturity of any Debenture or alter the provisions with respect to the redemption
of the Debentures (other than the provisions described under the caption
"-- Repurchase at the Option of Holders") or amend or modify the calculation of
the Accreted Value so as to reduce the amount of the Accreted Value of the
Debentures, (c) reduce the rate of or change the time for payment of interest on
any Debenture, (d) waive a Default or Event of Default in the payment of
principal of or premium, if any, or interest or Liquidated Damages, if any, on
the Debentures (except a rescission of acceleration of the Debentures by the
Holders of at least a majority in aggregate principal amount at maturity of the
Debentures and a waiver of the payment default that resulted from such
acceleration), (e) make any Debenture payable in money other than that stated in
the Debentures, (f) make any change in the provisions of the Indenture relating
to waivers of past Defaults, (g) waive a redemption payment with respect to any
Debenture (other than the provisions described under the caption "-- Repurchase
at the Option of Holders"), (h) make any change in the foregoing amendment and
waiver provisions, (i) modify any provision of the Indenture with respect to the
priority of the Debentures in right of payment or (j) make any change to the
right of Holders to waive an existing Default or Event of Default or the right
of Holders to receive payments of principal, premium, if any, and interest and
Liquidated Damages, if any, on the Debentures.
 
     Notwithstanding the foregoing, any amendment to or waiver of the covenant
described under the caption "-- Repurchase at the Option of Holders -- Change of
Control" will require the consent of the Holders of at least two-thirds in
aggregate principal amount at maturity of the Debentures then outstanding if
such amendment would materially adversely affect the rights of Holders of
Debentures. Notwithstanding the foregoing, without the consent of any Holder of
Debentures, the Issuer and the Trustee may amend or supplement the Indenture or
the Debentures to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Debentures in addition to or in place of certificated Debentures,
to provide for the assumption of the Issuer's obligations to Holders of
Debentures in the case of a merger or consolidation or sale of all or
substantially all of the Issuer's assets, to make any change that would provide
any additional rights or benefits to the Holders of Debentures or that does not
materially adversely affect the legal rights under the Indenture
 
                                       81
<PAGE>   83
 
of any such Holder, or to comply with requirements of the Commission in order to
effect or maintain the qualification of the Indenture under the Trust Indenture
Act or to provide for guarantees of the Debentures.
 
CONCERNING THE TRUSTEE
 
     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Issuer, to obtain payment of claims in
certain cases, or to realize on 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, apply to the Commission for permission to continue
or resign.
 
     The Holders of a majority in principal amount at maturity of the then
outstanding Debentures 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 (which shall not be cured), the Trustee will be required, in
the exercise of its power, to use the degree of care of a prudent man 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 Holder of Debentures, unless such Holder shall have
offered to the Trustee security and indemnity satisfactory to it against any
loss, liability or expense.

such Capital Stock provide that the Issuer may not repurchase or redeem any such
Capital Stock pursuant to such provisions unless such repurchase or redemption
complies with the covenant described under the caption "-- Certain
Covenants -- Restricted Payments," and provided further that, if such Capital
Stock is issued to any plan for the benefit of employees of the Issuer or its

subsequent to the commencement of the period for which the Fixed Charge Coverage
Ratio is being calculated but prior to the date on which the event for which the
calculation of the Fixed Charge Coverage Ratio is made (the "Calculation Date"),
then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect
to such incurrence, assumption, guarantee or redemption of Indebtedness, or such
issuance or redemption of preferred stock, as if the same had occurred at the
beginning of the applicable four-quarter reference period. In addition, for
purposes of making the computation referred to above, acquisitions that have
been made by the Issuer or any of its Subsidiaries, including all mergers or
consolidations and any related financing transactions, during the four-quarter
reference period or subsequent to such reference period and on or prior to the
Calculation Date shall be calculated to include the Consolidated Cash Flow of
the acquired entities on a pro forma basis after giving effect to cost savings
resulting from employee terminations, facilities consolidations and closings,
standardization of employee benefits and compensation practices, consolidation
of property, casualty and other insurance coverage and policies, standardization
of sales and distribution methods, reductions in taxes other than income taxes
and other cost savings reasonably expected to be realized from such acquisition,
as determined in good faith by an officer of the Issuer (regardless of whether
such cost savings could then be reflected in pro forma financial statements
under GAAP, Regulation S-X promulgated by the Commission or any other regulation
or policy of the Commission) and without giving effect to clause (c) of the
proviso set forth in the definition of Consolidated Net Income, and shall be
deemed to have occurred on the first day of the four-quarter reference period
and Consolidated Cash Flow for such reference period shall be calculated.

             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
     The following discussion is a summary of certain federal income tax
considerations relevant to the exchange of Old Debentures for New Debentures,
but does not purport to be a complete analysis of all potential tax effects. The
discussion is based upon the Internal Revenue Code of 1986, as amended, Treasury
regulations, Internal Revenue Service rulings and pronouncements, and judicial
decisions now in effect, all of which are subject to change at any time by
legislative, judicial or administrative action. Any such changes may be applied
retroactively in a manner that could adversely affect a holder of the New
Debentures. The description does not consider the effect of any applicable
foreign, state, local or other tax laws or estate or gift tax considerations.
 
     EACH HOLDER SHOULD CONSULT HIS OWN TAX ADVISOR AS TO THE PARTICULAR TAX
CONSEQUENCES TO IT OF EXCHANGING OLD DEBENTURES FOR NEW DEBENTURES, INCLUDING
THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS.
 
EXCHANGE OF OLD DEBENTURES FOR NEW DEBENTURES
 
     The exchange of Old Debentures for New Debentures pursuant to the Exchange
Offer should not constitute a sale or exchange for federal income tax purposes.
Accordingly, such exchange should have no federal income tax consequences to
holders of Old Debentures.

                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that receives New Debentures for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Debentures. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of New Debentures received in
exchange for Old Debentures where such Old Debentures were acquired as a result
of market-making activities or other trading activities. The Company has agreed
that, for a period of 90 days after the Expiration Date, it will make this
Prospectus, as amended or supplemented, available to any broker-dealer for use
in connection with any such resale. In addition, until             , 1998, all
dealers effecting transactions in the New Debentures may be required to deliver
a Prospectus.
 
     The Company will not receive any proceeds from any sale of New Debentures
by broker-dealers. New Debentures received by broker-dealers for their own
account pursuant to the Exchange Offer may be sold from time to time in one or
more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the New Debentures 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
broker-dealer or the purchasers of any such New Debentures. Any broker-dealer
that resells New Debentures that were received by it for its own account
pursuant to the Exchange Offer and any broker or dealer that participates in a
distribution of such New Debentures may be deemed to be an "underwriter" within
the meaning of the Securities Act, and any profit on any such resale of New
Debentures and any commissions or concessions received by any such persons may
be deemed to be underwriting compensation under the Securities Act. The Letter
of Transmittal states that by acknowledging that it will deliver and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act.
 
     For a period of 90 days after the Expiration Date, the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company has agreed to pay all expenses
incident to the Exchange Offer other than commissions or concessions of any
broker-dealers and will indemnify holders of the Old Debentures (including any
broker-dealers) against certain liabilities, including certain liabilities under
the Securities Act.
 
                                 LEGAL MATTERS
 
     The validity of the New Debentures offered hereby will be passed upon for
the Company by Weil, Gotshal & Manges LLP, Dallas, Texas and New York, New York.

           UNAUDITED CONDENSED CONSOLIDATED PRO FORMA FINANCIAL DATA
 
     The following unaudited condensed consolidated pro forma financial data
(the "Pro Forma Financial Data") of the Company are based on historical
consolidated financial statements of the Company as adjusted to give effect to
certain transactions described below and to the Merger, including the Merger
Financing and the application of the proceeds thereof. For additional
information regarding the Merger, see "The Merger and the Merger Financing." The
unaudited condensed consolidated pro forma statement of operations for the
quarter ended March 31, 1998 gives effect to the Merger and the Merger Financing
and the application of the proceeds thereof as if it had occurred at the
beginning of such period. The unaudited condensed consolidated pro forma
statement of operations for the twelve months ended March 31, 1998 and the year
ended December 31, 1997 give effect to the Arcsys Acquisition and the Woodland
Acquisition and, in the case of the year ended December 31, 1997, the GenSet
Acquisition, and the Merger, including the Merger Financing and the application
of the proceeds thereof, as if they all had occurred at the beginning of the
respective period. The pro forma statement of operations data have been derived
as if the balance sheet of the Company at the beginning of the respective period
was the pro forma balance sheet as of March 31, 1998. For additional information
regarding the GenSet Acquisition, the Arcsys Acquisition and the Woodland
Acquisition, see the discussion under the caption "Recent
Events -- Acquisitions" in Note 2 to the Company's Consolidated Financial
Statements. The unaudited condensed consolidated pro forma balance sheet gives
effect to the Merger, including the Merger Financing and the application of the
proceeds thereof, as if it had occurred on March 31, 1998. The pro forma
adjustments are based upon available information and upon certain assumptions
that management believes are reasonable under the circumstances. The Pro Forma
Financial Data and accompanying notes should be read in conjunction with the
historical consolidated financial statements of the Company, including the notes
thereto, and other financial information pertaining to the Company. The Pro
Forma Financial Data do not purport to represent what the Company's actual
results of operations or actual financial position would have been if the
Merger, including the Merger Financing and the application of the proceeds
thereof, and the GenSet Acquisition, the Arcsys Acquisition and the Woodland
Acquisition in fact occurred on such dates or to project the Company's results
of operations or financial position for any future period or date. The Pro Forma
Financial Data do not give effect to any transactions other than the GenSet
Acquisition, the Arcsys Acquisition, the Woodland Acquisition and the Merger,
including the Merger Financing and the application of the proceeds thereof,
discussed in the notes to the Pro Forma Financial Data included elsewhere
herein.
 
     As a result of the Merger, the Company incurred various expenses in
connection with consummating the transaction. See Note 2 to the Unaudited
Condensed Consolidated Pro Forma Statement of Operations for a more detailed
explanation of these expenses. While the exact timing, nature and amount of
these costs have not yet been fully determined, the Company anticipates that a
significant one-time pretax charge will be recorded in its second fiscal
quarter. As a result of the foregoing, the Company expects to record a
significant net loss in its second fiscal quarter. Because this loss will result
directly from the one-time charge incurred in connection with the Merger, and
this charge will be funded entirely through the proceeds of the Merger
Financing, the Company does not expect this loss to materially impact its
liquidity, ongoing operations or market position. For a discussion of the
consequences of the incurrence of indebtedness in connection with the Merger
Financing, see "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."
 
     The pro forma adjustments were applied to the respective historical
consolidated financial statements of the Company to reflect and account for the
Merger as a recapitalization; accordingly, the historical basis of the Company's
assets and liabilities has not been impacted thereby.

     (a) Assumes that all of the Outstanding Subordinated Notes and Outstanding
         Senior Notes are purchased by Holdings. The purchase by Holdings of
         less than 100% of each of such notes would result in a reduction in the
         amount of borrowings under the New Credit Facility; however, management
         does not believe that such changes would have a material effect on the
         information presented herein.
 
     (b) Represents the issuance of $207 million aggregate principal amount of
         Senior Subordinated Notes at a discount.
 
(2) Represents the portion of estimated transaction fees and expenses
    attributable to the New Credit Facility, the Senior Subordinated Notes, the
    Debentures and related interim financing commitments. See Note 6 to the
    Company's Unaudited Condensed Consolidated Pro Forma Statement of
    Operations.
 
(3) The adjustment reflects the $5.6 million write-off of deferred debt issuance
    costs associated with retiring the existing indebtedness. See Notes 2 and 6
    to the Company's Unaudited Condensed Consolidated Pro Forma Statement of
    Operations for an explanation of the pro forma income statement impact.

 (1) Represents the financial results for the companies acquired during 1997 for
     the periods not included in the Company Historical column as follows:
     Arcsys (4/1/97-9/25/97) and Woodland (4/1/97-11/24/97).
 
 (2) The pro forma balance sheet reflects non-recurring charges aggregating
     $58.1 million (comprised of $18.1 million related to employee stock options
     and related plans; $17.4 million of non-capitalizable transaction fees;
     $16.8 million of debt pre-payment penalties and the write-off of $5.6
     million of related deferred issuance costs) and estimated tax benefits of
     $16.8 million. The amounts related to debt prepayment penalties and debt
     issuance costs will be reflected net of tax benefits as an extraordinary
     item. These amounts have not been reflected in the unaudited pro forma
     consolidated statements of operations.
 
 (3) Reflects the additional interest expense and associated tax benefit
     attributable to the acquisitions, all of which were financed with
     borrowings under the Company's revolving credit facility.

                PRO FORMA STATEMENT OF OPERATIONS -- (CONTINUED)
 
     (b) Calculations based on LIBOR at 5.63%.
 
     The borrowings under the New Credit Facility assume that all of the
     Outstanding Subordinated Notes and Outstanding Senior Notes are purchased
     by Holdings. The purchase by Holdings of less than 100% of each of such
     notes would result in a reduction in the amount of borrowings under the New
     Credit Facility; however, management does not believe that such changes
     would have a material effect on the information presented herein.

                   NOTES TO UNAUDITED CONDENSED CONSOLIDATED
                PRO FORMA STATEMENT OF OPERATIONS -- (CONTINUED)
 
(10) "Adjusted EBITDA" is defined as operating income plus depreciation,
     amortization of goodwill, amortization of intangibles and net periodic
     postretirement benefits expense and is a key financial measure but should
     not be construed as an alternative to operating income or cash flows from
     operating activities (as determined in accordance with generally accepted
     accounting principles). Adjusted EBITDA is also one of the financial
     measures by which the Company's compliance with its covenants is calculated
     under its debt agreements. The Company believes that Adjusted EBITDA is a
     useful supplement to net income (loss) and other consolidated income
     statement data in understanding cash flows generated from operations that
     are available for taxes, debt service and capital expenditures. However,
     the Company's method of computation may or may not be comparable to other
     similarly titled measures of other companies. In addition, Adjusted EBITDA
     is not necessarily indicative of amounts that may be available for
     discretionary uses and does not reflect any legal or contractual
     restrictions on the Company's use of funds.
 
(11) For purposes of calculating the ratio of earnings to fixed charges,
     earnings consist of income before income taxes plus fixed charges. Fixed
     charges consist of interest expense, amortization of deferred financing
     costs and one-third of the rent expense from operating leases, which
     management believes is a reasonable approximation of the interest component
     of rent expense.

     (a) A one-eighth of one percent change in interest rates would impact
        interest expense for borrowings under the New Credit Facility, the
        Senior Subordinated Notes and the Debentures, collectively, in the
        amount of approximately $0.2 million and $0.8 million for the three
        months ended March 31, 1998 and the year ended December 31, 1997,
        respectively.
 
     (b) Calculations based on LIBOR at 5.63%.
 
     The borrowings under the New Credit Facility assume that all of the
     Outstanding Subordinated Notes and Outstanding Senior Notes are purchased
     by Holdings. The purchase by Holdings of less than 100% of each of such
     notes would result in a reduction in the amount of borrowings under the New
     Credit Facility; however, management does not believe that such changes
     would have a material effect on the information presented herein.
 
 (5) Reflects the elimination of interest expense attributable to indebtedness
     to be paid in connection with the Merger, as follows:

     Financing costs are amortized using the effective interest method.
 
 (7) Adjustment reflects the income tax effect of all pro forma entries above at
     a rate of 35.0%.
 
 (8) Reflects dividends on preferred stock issued in the Merger ($50 million
     liquidation preference multiplied by a 13% dividend rate).
 
 (9) Assuming the warrants to purchase shares of common stock to be issued in
     connection with the Merger Financing had been issued as of January 1, 1997
     and January 1, 1998 with an exercise price of $0.01 per share, the pro
     forma 1997 income (loss) and pro forma first quarter 1998 income (loss)
     from continuing operations available to common would have been ($19.3)
     million and ($12.5) million, respectively.
 
(10) "EBITDA" is defined as operating income plus depreciation, amortization of
     goodwill, amortization of intangibles and net periodic postretirement
     benefits expenses and is a key financial measure but should not be
     construed as an alternative to operating income or cash flows from
     operating activities (as determined in accordance with generally accepted
     accounting principles). EBITDA is also one of the financial measures by
     which the Company's compliance with its covenants is calculated under its
     debt agreements. The Company believes that EBITDA is a useful supplement to
     net income (loss) and other consolidated income statement data in
     understanding cash flows generated from operations that are available for
     taxes, debt service and capital expenditures. However, the Company's method
     of computation may or may not be comparable to other similarly titled
     measures of other companies.
 
(11) For purposes of calculating the ratio of earnings to fixed charges,
     earnings consist of income before income taxes plus fixed charges. Fixed
     charges consist of interest expense, amortization of deferred financing
     costs and one-third of the rent expense from operating leases, which
     management believes is a reasonable approximation of the interest component
     of rent expense.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors
Thermadyne Holdings Corporation
 
     We have audited the accompanying consolidated balance sheets of Thermadyne
Holdings Corporation and subsidiaries as of December 31, 1997 and 1996, and the
related consolidated statements of operations, stockholders' equity (deficit),
and cash flows for each of the three years in the period ended December 31,
1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Thermadyne Holdings Corporation and subsidiaries at December 31, 1997 and 1996,
and the consolidated results of its operations and cash flows for each of the
three years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles.

                       (IN THOUSANDS, EXCEPT SHARE DATA)
 
1. THE COMPANY
 
     Thermadyne Holdings Corporation ("Thermadyne" or "the Company"), a Delaware
corporation, is a global manufacturer of cutting and welding products and
accessories. Thermadyne's year end is December 31.
 
2. RECENT EVENTS
 
  MERGER WITH MERCURY ACQUISITION CORPORATION
 
     On January 20, 1998, the Company and Mercury Acquisition Corporation
("Mercury"), an affiliate of DLJ Merchant Banking Partners II, L.P. ("DLJ"),
entered into a definitive merger agreement (the "Merger Agreement"). Under the
terms of the Merger Agreement, Mercury will merge with and into the Company,
and, subject to the following sentence, the holders of each share of the
Company's common stock can elect to receive $34.50 in cash for such share or to
retain such share in the merged Company. In any event, holders will be required
to retain 485,010 shares, or 4.3%, of the Company's common stock outstanding
immediately prior to the merger. In addition, DLJ has entered into voting
agreements with Magten Asset Management (on behalf of itself and certain of its
clients) and Fidelity Capital and Income Fund, pursuant to which these current
shareholders, subject to certain conditions, have agreed to vote in favor of the
merger 5,942,708 shares of the Company's common stock owned by them. These
shares represent approximately 53% of the Company's common stock outstanding on
December 31, 1997.
 
     The proposed merger, which will be recorded as a recapitalization for
accounting purposes, is subject to a number of conditions, including regulatory
approvals and approval by Company stockholders. The transaction is estimated to
have an aggregate value of approximately $790 million, including refinancing of
the Company's existing revolving credit facility and senior and subordinated
notes. The Company expects the merger to close by June 30, 1998.
 
     As a result of the proposed merger, the Company and Mercury will incur
various costs, currently estimated to range between $50 million and $60 million,
on a pretax basis, in connection with consummating the transaction. These costs
consist primarily of professional fees, registration costs, compensation costs
and other expenses. Although the exact timing, nature and amount of these merger
transaction costs are subject to change, the Company expects that a one-time
charge for these costs will be recorded in the quarter during which the merger
is consummated.
 
  ACQUISITIONS
 
     On November 25, 1997, the Company acquired substantially all of the assets
of Woodland Cryogenics, Incorporated, a manufacturer of cryogenic pumps, ambient
and electric vaporizers and automatic cylinder filling systems located in
Philadelphia, Pennsylvania. The aggregate consideration paid was approximately
$2,500 and was financed through bank facilities. The transaction was accounted
for as a purchase.
 
     On September 26, 1997, the Company acquired substantially all of the assets
of the welding division of Prestolite Power Corporation, a manufacturer of arc
welders, plasma welders and wire feeders, located in Troy, Ohio. The aggregate
consideration paid was approximately $7,500 and was financed through bank
facilities. The transaction was accounted for as a purchase.
 
     On January 31, 1997, the Company acquired all of the issued and outstanding
capital stock of GenSet S.p.A., a leading manufacturer of engine-driven welders
and generators in Italy. The aggregate consideration paid was approximately
$28,000 and was financed through bank facilities. The transaction was accounted
for as a purchase.

was paid in cash which was financed through cash on hand and borrowing under the
Company's existing credit agreement. This transaction was accounted for as a
purchase.

</TABLE>
 
     On April 26, 1996, the Company completed the sale of substantially all of
the assets of Coyne Cylinder Company ("Coyne"), and on June 27, 1996, the
Company completed the sale of its Floor Maintenance business. Consideration
received from these two transactions totaled $137,000 and consisted of $112,359
in cash and $24,641 in the assumption or elimination of certain liabilities. The
Company realized a net gain of $8,480 on these two transactions, net of income
taxes of $14,732. The net proceeds were used to reduce debt. The financial
results of the Coyne and Floor Maintenance operations were reported separately
as discontinued operations in the Consolidated Statements of Operations.
 
     Sales from the discontinued businesses totaled $76,163, $183,440 and
$259,772 for the years ended December 31, 1997, 1996 and 1995, respectively.
Certain expenses have been allocated to discontinued operations including
interest expense, which was allocated on a ratio of earnings before interest,
taxes, depreciation and amortization for the years presented. Interest expense
allocated to discontinued operations was $2,048, $7,630 and $11,413 for the
years ended December 31, 1997, 1996 and 1995, respectively. Income (loss) from
discontinued operations included in the accompanying Consolidated Statements of
Operations include immaterial amounts of income taxes (see Note 11).
 
3. SIGNIFICANT ACCOUNTING POLICIES
 
     The consolidated financial statements include the accounts of Thermadyne
and its wholly owned subsidiaries. All material intercompany balances and
transactions have been eliminated in consolidation. Certain amounts from prior
years have been reclassified to conform to current year presentation.
 
     Preparation of financial statements in conformity with generally accepted
accounting principles requires certain estimates and assumptions be made that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
     Inventories -- Inventories are valued at the lower of cost or market. Cost
is determined using the last-in, first-out ("LIFO") method for domestic
subsidiaries and the first-in, first-out ("FIFO") method for foreign
subsidiaries. Inventories at foreign subsidiaries amounted to approximately
$46,798 and $33,567 at December 31, 1997 and 1996, respectively.
 
     Property, Plant and Equipment -- Property, plant and equipment is carried
at cost and is depreciated using the straight-line method. The average estimated
lives utilized in calculating depreciation are as follows: buildings - 25 years;
and machinery and equipment -two to ten years.
 
     Deferred Financing Costs -- The Company capitalizes loan origination fees
and other costs incurred arranging long-term financing. These costs are
amortized over the respective lives of the obligations using the effective
interest method.
 
                                       F-9
<PAGE>   117
                        THERMADYNE HOLDINGS CORPORATION
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Intangibles -- The excess of costs over the net tangible assets of
businesses acquired consists of assembled work forces, customer and distributor
relationships, patented and unpatented technology, and goodwill. In conjunction
with the 1993 financial reorganization of the Company, assets and liabilities
were revalued as of February 1, 1994. The assets were stated at their
reorganization value which is defined as the fair value of the reorganized
company (see Note 7). The portion of the reorganization value not attributable
to specific assets was amortized over a three-year period. Identified intangible
assets are amortized on a straight-line basis over the various estimated useful
lives of such assets, which generally range from three to 25 years. Goodwill
related to acquisitions subsequent to the financial reorganization is amortized
over 40 years.
 
     Income Taxes -- The Company accounts for income taxes using the liability
method required by Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes." Under the liability method, deferred tax assets
and liabilities are recognized for the estimated future tax consequences
attributable to temporary differences between the carrying value of assets and
liabilities for financial reporting purposes and their tax bases and
carryforward items. The measurement of current and deferred tax assets and
liabilities is based on provisions of the enacted tax law; the effects of future
changes in tax laws or rates are not anticipated. The measurement of deferred
tax assets is reduced, if necessary, by the amount of any tax benefits that,
based on available evidence, are not expected to be realized.
 
     Revenue Recognition -- Revenue from the sale of cutting and welding
products is recognized upon shipment to the customer. Costs and related expenses
to manufacture cutting and welding products are recorded as cost of sales when
the related revenue is recognized.
 
     Earnings Per Share -- In 1997, the Financial Accounting Standards Board
issued Statement No. 128, "Earnings per Share" ("FASB 128"). FASB 128 replaced
the calculation of primary and fully diluted earnings per share with basic and
diluted earnings per share. Unlike primary earnings per share, basic earnings
per share excludes any dilutive effects of options, warrants and convertible
securities. Diluted earnings per share is very similar to the previously
reported fully diluted earnings per share. All earnings per share amounts for
all periods have been presented to conform to the Statement 128 requirements.
The effects of options, warrants and convertible securities have not been
considered for the years ended December 31, 1996 and 1995 because the result
would be antidilutive. All exchange arrangements contemplated by the Company's
1994 financial restructuring are assumed to have been completed.

     Stock Based Compensation -- The Company grants stock options for a fixed
number of shares to employees with an exercise price equal to the fair value of
the shares at the date of grant, and also through its Employee Stock Purchase
Plan enables substantially all employees to purchase shares of common stock at a
purchase price of 85% of the fair market value at specified dates. The Company
accounts for these stock option grants in accordance with Accounting Principles
Board Opinion No. 25 -- "Accounting for Stock Issued to Employees" ("APB 25"),
and, accordingly, recognizes no compensation expense for the stock option
grants.
 
     Statement of Cash Flows -- For purposes of the statement of cash flows,
Thermadyne considers all highly liquid investments purchased with a maturity of
three months or less to be cash equivalents. The carrying value of cash and cash
equivalents approximates fair value because of the short maturity of these
investments.
 
     The following table shows the interest and taxes paid during the periods

     Foreign Currency Translation -- Local currencies have been designated as
the functional currencies for all subsidiaries. Accordingly, assets and
liabilities of foreign subsidiaries are translated at the rates of exchange at
the balance sheet date. Income and expense items of these subsidiaries are
translated at average monthly rates of exchange. The resultant translation gains
or losses are included in the component of shareholders' equity designated
"Foreign currency translation." The Company's foreign operations are discussed
in Note 13.

     Recent Accounting Pronouncements -- As of January 1, 1998, the Company
adopted Statement 130, Reporting Comprehensive Income. Statement 130 establishes
new rules for the reporting and display of comprehensive income and its
components; however, the adoption of this Statement had no impact on the
Company's net income or shareholders' equity. Statement 130 requires foreign
currency translation adjustments, which prior to adoption were reported
separately in shareholders' equity, to be included in other comprehensive
income. Prior year financial statements have been reclassified to conform to the
requirements of Statement 130.
 
     In June 1997, the FASB issued Statement No. 131, "Disclosures about
Segments of an Enterprise and Related Information" ("FASB 131"), which requires
publicly-held companies to report financial and descriptive information about
its operating segments in financial statements issued to shareholders for
interim and annual periods. The statement also requires additional disclosures
with respect to products and services, geographical areas of operations, and
major customers. FASB 131 is effective for fiscal years beginning after December
15, 1997 and requires restatement of earlier periods presented.
 
4. ACCOUNTS RECEIVABLE
 
     The Company has entered into a trade accounts receivable securitization
agreement whereby it will sell on an ongoing basis, through December 28, 1999,
participation interests in up to $50,000 of designated accounts receivable. The
amount of participation interests sold under this financing arrangement is
subject to change based on the level of eligible receivables and restrictions on
concentrations of receivables, and was approximately $28,305 and $22,629 at
December 31, 1997 and 1996, respectively. The sold accounts receivable are
reflected as a reduction of accounts receivable on the Consolidated Balance
Sheets. Interest expense is incurred on participation interests at the rate of
one-month LIBOR plus 50 basis points, per annum (approximately 6.48% at December
31, 1997). The fair value of accounts receivable approximates the carrying
value.
 
     During the year ended December 31, 1997, the Company adopted FASB Statement
No. 125, "Accounting for Transfers and Servicing of Financial Assets and
Extinguishments of Liabilities" ("FASB 125"). FASB 125 is required to be applied
to transfers of assets occurring after January 1, 1997. The effect of adopting
FASB 125 was immaterial.

</TABLE>
 
     Prior to 1995, the Company assessed the recoverability of its identifiable
intangible assets primarily based on its current and anticipated future
undiscounted cash flows, which included disbursements for interest expense. In
the fourth quarter of 1995, the Company early adopted Financial Accounting
Standards Board Statement No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed Of," ("FASB 121") and
consequently revalued amounts capitalized for customer and distributor
relationships and for patented and unpatented technology given recent
fundamental changes in its core businesses. Based on this revaluation, the
Company determined that assets with a carrying amount of $67,923 were impaired
and wrote them down by $32,972 to their estimated fair value. Fair value was
based on the estimated future cash flows to be generated by these assets,
discounted at a market rate of interest. The writedown is included in the
amortization of other intangibles line item on the Consolidated Statements of
Operations. In the fourth quarter of 1996, the carrying value of intangible
assets recorded in connection with the Company's financial reorganization was
reduced by approximately $2,400 resulting from the initial recognition of the
Company's net deferred tax asset. The carrying value of these intangibles was
further reduced during 1997 by approximately $26,000 upon the recognition of net
operating loss carryforward benefits and the sale of the Wear Resistance
business.

     On June 25, 1996 the Company amended and restated its domestic credit
agreement (the "Domestic Facility") to a $250,000 revolving credit and letters
of credit facility with a consortium of 22 banks. The term is five years and the
banks' commitment reduces by $25,000 at the end of year three and by an
additional $75,000 at the end of year four. At the Company's option, interest
accrues at (i) the prime rate plus an applicable margin in the range of
0.5% -- 1.25% or, (ii) LIBOR plus an applicable margin in the range of
1.5% -- 2.25%. The applicable margin percentage is dependent upon the Company
meeting certain financial conditions. At December 31, 1997 the prime rate was
8.5%. The facility contains financial covenants which, among other things,
require the Company to maintain certain financial ratios and restrict the
Company's ability to incur indebtedness, make capital expenditures, and pay
dividends. The facility is secured by the capital stock, personal and real
property of the Company and a significant portion of its subsidiaries' capital
stock and personal and real property. At December 31, 1997 the Company had
$10,349 of standby letters of credit outstanding under its Domestic Facility.
Unused borrowing capacity under the Domestic Facility was $198,151.
 
     The Australian credit agreement (the "Australian Facility") is denominated
in Australian dollars ("A$") and expires on December 31, 2000. The Australian
Facility consists of an A$15,000 term commitment and an A$22,000 revolving
credit commitment. The Australian Facility bears interest at the Bank Bill Rate
(as defined) plus a margin of 1.5% for the term commitment and 0.75% for the
revolving credit commitment. At December 31, 1997 the Company's average
applicable Bank Bill Rate (as defined) was 4.987%. Interest payment dates vary
depending on the funding period selected by the Company. Total mandatory
principal reductions under the term commitment for the remainder of its term are
as follows: 1998 -- A$3,000; 1999 -- A$4,000; and 2000 -- A$4,000. The facility
requires the Company's Australian subsidiary to comply with various financial
covenants. The facility is secured by personal and real property of

the Company's Australian subsidiary. At December 31, 1997 the Company had A$383
of letters of credit outstanding under the Australian Facility. Unused borrowing
capacity under the Australian Facility was A$1,500.
 
     The indentures governing the senior notes and the subordinated notes
restrict, subject to certain exceptions, the Company and its subsidiaries from
incurring additional debt, paying dividends or making other distributions on or
redeeming or repurchasing capital stock, making investments, loans or advances,
disposing of assets, creating liens on assets and engaging in transactions with
affiliates.
 
     The estimated fair value amounts of the Company's long-term obligations
have been determined by the Company using available market information and
appropriate valuation methodologies. Considerable judgment is required to
develop the estimates of fair value; thus, the estimates provided herein are not
necessarily indicative of the amounts that could be realized in a current market
exchange. The use of different market assumptions or valuation methodologies may
have a material effect on the estimated fair value amounts. The fair value of
the senior notes and the subordinated notes was based on the most recent market
information available, and is estimated to be 104.25% and 107.0% of their
current carrying values at December 31, 1997, or $103,508 and $191,873,
respectively. The fair values of the credit agreement and the Company's other
long-term obligations are estimated at their current carrying values since these
obligations are fully secured and have varying interest charges based on current
market rates.
 
9. STOCK OPTIONS
 
     The Company has elected to follow APB 25 and related Interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under Financial Accounting
Standards Board Statement No. 123, "Accounting for Stock-Based Compensation"
("FASB 123"), requires use of option valuation models that were not developed
for use in valuing employee stock options. Under APB 25, because the exercise
price of the Company's employee stock options equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.
 
     Pro forma information regarding net income and earnings per share is
required by FASB 123, which also requires that the information be determined as
if the Company has accounted for its employee stock options granted subsequent
to December 31, 1994 under the fair value method of that statement. The fair
value for these options was estimated at the date of grant using a Black-Scholes
option pricing model with the following weighted-average assumptions for 1997,
1996 and 1995, respectively: risk-free interest rates of 6.1%, 5.5% and 6.4%; a
dividend yield of 0.0% for each year presented; volatility factors of the
expected market price of the Company's common stock of 0.38, 0.39 and 0.42; and
a weighted-average expected life of the options of six years for each year
presented.
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

periods.
 
     The Company has three option plans for the grant of options to its
employees and directors. The 1993 Management Option Plan (the "1993 Management
Plan") provides for the grant of options to acquire up to 1,428,570 shares of
common stock to key officers and employees of the Company or its affiliates.
Grants under the 1993 Management Plan are exercisable in installments ranging
from immediately on the date of grant to not later than five years from the date
of grant. The Non-Employee Directors Plan (the "1995 Directors Plan") provides
for the grant of options to acquire up to 50,000 shares of common stock to
non-employee directors of the Company. Grants under the 1995 Directors Plan vest
immediately on the date of grant. The 1996 Employee Stock Option Plan (the "1996
Employee Plan") initially provided for the grant of options to acquire up to
300,000 shares of common stock to employees of the Company. This plan was
amended in 1996 to provide for the grant of options to acquire up to an
additional 500,000 shares of common stock. Grants under the 1996 Employee Plan
vest ratably over five years. All options granted under the three plans
described above are non-qualified stock options granted at 100% of the fair
market value on the grant dates.

     In the fourth quarter of 1996, the Company re-evaluated the realizability
of the net deferred tax asset. As a result, a net deferred tax asset of
approximately $22,000 was recorded on December 31, 1996. Of the total amount
recorded, approximately $8,000 was reported as an adjustment to the carrying
value of goodwill and other intangible assets. The balance was reported as a
reduction to income tax expense. A portion of the net adjustment for deferred
taxes has been allocated to discontinued operations. The valuation allowance

net operating loss carryforwards existing on February 1, 1994, the effective
date of the Company's financial reorganization.
 
     At December 31, 1997, the Company had net operating loss carryforwards of
approximately $85,000 for U.S. income tax purposes that begin to expire in the
year 2001. The consummation of the financial reorganization resulted in an
ownership change under Section 382 of the Internal Revenue Code. As a result,
the Company's utilization of these losses to offset future U.S. taxable income
is limited to approximately $7,000 per year. Pursuant to the requirements of the
American Institute of Certified Public Accountants Statement of Position No.
90-7, entitled "Financial Entities in Reorganization Under the Bankruptcy Code",
to the extent net operating losses that existed on the effective date of the
Company's financial reorganization are recognized, the resulting tax benefit
will be reported as a direct addition to paid-in capital.
 
     The Company's foreign subsidiaries have undistributed earnings at December
31, 1997. Those earnings are considered to be indefinitely reinvested and,
accordingly, no provision for U.S. federal and state income taxes has been
provided thereon. Upon distribution of those earnings in the form of dividends
or otherwise, the Company would be subject to both U.S. income taxes (subject to
an adjustment for foreign tax credits) and withholding taxes payable to the
various foreign countries. Determination of the amount of unrecognized deferred
U.S. income tax liability is not practicable because of the complexities
associated with its hypothetical calculation.
 
12. EMPLOYEE BENEFIT PLANS
 
     401(k) Retirement Plan -- The 401(k) Retirement Plan covers the majority of
the Company's domestic employees. The Company, at its discretion, can make a
base contribution of 1% of each employee's compensation and an additional
contribution equal to as much as 4% of the employee's compensation. At the
employee's discretion, an additional 1% to 15% voluntary employee contribution
can be made. The plan requires the Company to make a matching contribution of
50% of the first 6% of the voluntary employee contribution. Total expense for
this plan related to continuing operations was approximately $2,628, $2,585, and
$1,897 for the years ended December 31, 1997, 1996 and 1995, respectively.
 
     Employee Stock Purchase Plan -- The Employee Stock Purchase Plan enables
substantially all employees of the Company to purchase shares of common stock at
a purchase price of 85% of the fair market value at specified dates. For plan
year 1997, the plan was amended to change the plan year to a calendar year
basis. For the plan year ended December 31, 1997, 1,098 employee participants
purchased 82,085 shares at an aggregate purchase price of $1,989. For the plan
year ended October 31, 1996, 1,090 employee participants purchased 145,584
shares at an aggregate purchase price of $2,119. In the initial plan year ended
October 31, 1995, 1,502 employee participants purchased 252,925 shares at an
aggregate purchase price of $2,327. A maximum of 1,000,000 shares is authorized
for purchase under the plan.
 
     Other Postretirement Benefits -- The Company has several retirement plans
covering both salaried and nonsalaried retired employees, which provide
postretirement health care benefits (medical and dental) and life insurance
benefits. The postretirement health care plan is contributory, with retiree
contributions adjusted annually as determined by the Company based on claim
costs. The postretirement life insurance plan is noncontributory. The Company
recognizes the cost of postretirement benefits on the accrual basis as employees
render service to earn the benefit. The Company continues to fund the cost of
health care and life insurance benefits in the year incurred.

</TABLE>
 
     In addition, for actuarial measurements purposes, the following assumptions
and methods were used: annual discount rate of 7% (7% at January 1, 1997),
medical claim cost trends with annual increases starting at 10.5% in 1996 and
decreasing incrementally to 6% in 2011 and thereafter. The medical cost trend
rate assumption has a significant effect on the amounts reported. To illustrate,
increasing the medical cost trend rate by 1% in each year would increase the
accumulated postretirement benefit obligation as of December 31, 1997 by
approximately $1,900 and the aggregate of the service and interest cost
components of net periodic postretirement benefit cost for the year ended
December 31, 1997, by approximately $307. The Company uses the amortization
method for recording gains or losses resulting from past experience different
from that assumed and changes in assumptions.

     Pension Plans -- The Company's subsidiaries have had various
noncontributory defined benefit pension plans which covered substantially all
U.S. employees. The Company froze its three noncontributory defined benefit
pension plans through amendments to such plans effective December 31, 1989. All
former participants of these plans became eligible to participate in the 401(k)
Retirement Plan effective January 1, 1990. The following table sets forth the

14. CONTINGENCIES
 
     Thermadyne and certain of its wholly owned subsidiaries are defendants in
various legal actions, primarily in the products liability area. While there is
uncertainty relating to any litigation, management is of the opinion that the
outcome of such litigation will not have a material adverse effect on the
Company's financial condition or results of operations.
 
     The Company is party to an agreement with a financial institution to sell
at face value up to a total of $25,000 of its long-term receivables. The product
line that generated these long-term receivables has been divested, and
consequently, no further sales will occur. Under the terms of this agreement,
the Company is liable for a total of 20% of the aggregate receivables sold and
this liability approximates $4,000. The Company has further retained collection
and administrative responsibilities on behalf of the financial institution. The
Company has a secured interest in the inventory sold under these long-term
receivables which has been assigned to the financial institution. At December
31, 1997, approximately $3,666 in contracts subject to this agreement are
outstanding. Management believes the allowance for doubtful accounts at December
31, 1997 will be adequate for all uncollectible receivables.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the General Corporation Law of the State of Delaware (the
"DGCL") permits a corporation to indemnify any of its directors or officers who
was or is a party, or is threatened to be made a party to any third party
proceeding by reason of the fact that such person is or was a director or
officer of the corporation, against expenses (including attorney's fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding, if such
person acted in good faith and in a manner such person 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 reason to believe that such person's
conduct was unlawful. In a derivative action, i.e., one by or in the right of
the corporation, the corporation is permitted to indemnify directors and
officers against expenses (including attorneys' fees) actually and reasonably
incurred by them in connection with the defense or settlement of an action or
suit if they acted in good faith and in a manner that they reasonably believed
to be in or not opposed to the best interests of the corporation, except that no
indemnification shall be made if such person shall have been adjudged liable to
the corporation, unless and only to the extent that the court in which the
action or suit was brought shall determine upon application that the defendant
directors or officers are fairly and reasonably entitled to indemnity for such
expenses despite such adjudication of liability.
 
     Article Eighth of the Company's Amended and Restated Certificate of
Incorporation makes mandatory indemnification expressly authorized under the
DGCL for directors of the Company. With respect to officers of the Company,
Article Eighth of the Company's Amended and Restated Certificate of
Incorporation provides indemnification to such extent and to such effect as the
Board of Directors shall determine to be appropriate and authorized by Delaware
law.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Securities Act"), may be permitted to directors,
officers and controlling persons of the Company pursuant to the foregoing
provisions, or otherwise, the Company has been advised that in the opinion of
the Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the Company of expenses incurred or paid by a director, officer or
controlling person thereof in the successful defense of any action, suit or
proceeding) is asserted by a director, officer or controlling person in
connection with the securities being registered, the Company 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 such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
     In connection with the merger of Mercury Acquisition Corporation
("Mercury") with and into the Registrant, Mercury issued 2,608,696 shares of its
common stock, 2,000,000 shares of its preferred stock and warrants to purchase
353,428 shares of its common stock for approximately $140 million. As a result
of the merger, each share of common stock of Mercury became a share of common
stock of the Registrant, each share of preferred stock of Mercury became a share
of preferred stock of the Registrant and each warrant to purchase common stock
of Mercury became exercisable for an equal number of shares of common stock of
the Registrant.
 
     On May 22, 1998, the Registrant sold $174,000,000 aggregate principal
amount at maturity of its 12 1/2% Senior Discount Debentures due 2008 (the "Old
Debentures") to Donaldson, Lufkin & Jenrette Securities Corporation (the
"Initial Purchaser") in a private placement in reliance on Section 4(2) under
the Securities Act, at a price equal to 54.374% of the stated principal amount
of such Old Debentures. The Old Debentures were immediately resold by the
Initial Purchasers in reliance on Rule 144A promulgated under the Securities
Act.

     (a) The undersigned Registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being

             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act;
 
             (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 end of the estimated
        maximum offering range may be reflected in the form of prospectus filed

     the offering of such securities at the 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.

                                   WITNESSETH:
         WHEREAS, MergerSub and the Company are parties to an Agreement and Plan
of Merger dated as of January 20, 1998 (the "AGREEMENT"); and

         WHEREAS, the parties desire to amend the Agreement in certain respects;

set forth herein and in the Agreement, the parties hereto agree as follows:

         1. Section 1.07(a) is hereby amended by deleting the opening clause
"Except as set forth on Schedule 1.07(a)," so that Section 1.07(a) now commences

                                                                          Page 3

         FOURTH: The total number of shares of stock which the Corporation shall
have authority to issue is 45,000,000, consisting of 30,000,000 shares of Common
Stock, par value $0.01 per share (the "COMMON STOCK"), and 15,000,000 shares of
Preferred Stock, par value $0.01 per share (the "PREFERRED STOCK"), of which
2,000,000 shares have been designated 13% Senior Exchangeable Preferred Stock
(the "SENIOR PREFERRED STOCK").

         The designations and the powers and preferences, rights,
qualifications, limitations and restrictions of the Common Stock and the
Preferred Stock are as follows:

         A.       Provisions Relating to the Common Stock

         Except as otherwise required by law, each holder of Common Stock shall
be entitled to one vote for each share of common stock standing in such holder's
name on the records of the Corporation on each matter submitted to a vote of the
stockholders.

         The holders of the Common Stock shall be entitled to receive when, as,
and if declared by the board of directors of the Corporation, out of funds
legally available therefor, dividends payable in cash, stock, or otherwise.

         Upon any liquidation, dissolution, or winding up of the Corporation,
whether voluntary or involuntary, and after the holders of any bonds,
debentures, or other obligations of the Corporation shall have been paid in full
the amounts to which they shall be entitled (if any), or a sum sufficient for
such payment in full shall have been set aside, the remaining net assets of the
Corporation shall be distributed pro rata to the holders of the Common Stock in
accordance with their respective rights and interests, to the exclusion of the
holders of any bonds, debentures, or other obligations of the Corporation.

         The Corporation may issue shares of its Common Stock from time to time
for such consideration (in any form, but not less in value than the par value
thereof) as may be fixed by the board of directors of the Corporation, which is
expressly authorized to fix the same in its absolute and uncontrolled discretion
subject to the foregoing conditions. Shares so issued for which the
consideration shall have been paid or delivered to the Corporation shall be
deemed fully paid stock and shall not be liable to any further call or
assessment thereon, and the holders of such shares shall not be liable for any
further payments in respect of such shares. The Corporation shall also have
authority to create and issue rights and options entitling their holders
to purchase or otherwise acquire shares of Common Stock and such rights and
options shall be evidenced by instrument(s) approved by the board of directors
of the Corporation. The board of directors of the Corporation shall be empowered
to set the exercise price, duration, times for exercise, and other terms of such
options or rights; provided, however, that the consideration to be received
(which may be in any form) for any shares of Common Stock subject thereto shall
have a value not less than the par value thereof.

         B.       Provisions Relating to the Preferred Stock

         The Board of Directors is hereby empowered to authorize by resolution
or resolutions from time to time the issuance of one or more classes or series
of Preferred Stock and to fix the designations, powers, preferences and
relative, participating, optional or other rights, if any, and the
qualifications, limitations or restrictions thereof, if any, with respect to
each such class or series of Preferred Stock and the number of shares
constituting each such class or series, and to increase or decrease the number
of shares of any such class or series to the extent permitted by the Delaware
Law.

         C.       Provisions Relating to the Senior Preferred Stock

         (1) NUMBER AND DESIGNATION. 2,000,000 shares of the Preferred Stock of
the Corporation shall be designated as 13% Senior Exchangeable Preferred Stock.

         (2) RANK. The Senior Preferred Stock shall, with respect to dividend
rights and rights on liquidation, dissolution and winding up, rank prior to all
classes of or series of common stock of the Corporation, including the
Corporation's Common Stock, and each other class of capital stock of the
Corporation, the terms of which provide that such class shall rank junior to the
Senior Preferred Stock or the terms of which do not specify any rank relative to
the Senior Preferred Stock. All equity securities of the Corporation to which
the Senior Preferred Stock ranks prior (whether with respect to dividends or
upon liquidation, dissolution, winding up or otherwise), including the Common
Stock, are collectively referred to herein as the "JUNIOR SECURITIES." All
equity securities of the Corporation with which the Senior Preferred Stock ranks
on a parity (whether with respect to dividends or upon liquida tion, dissolution
or winding up) are collectively referred to herein as the "PARITY SECURITIES."
The respective definitions of Junior Securities and Parity Securities shall also
include any rights or options exercisable for or convertible into any of the
Junior Securities and Parity Securities, as the case may be. The Senior
Preferred Stock shall be subject to the creation of Junior Securities.

                  (3) DIVIDENDS. (a) (i) The holders of shares of Senior
Preferred Stock shall be entitled to receive, when, as and if declared by the
Board of Directors, out of funds legally available for the payment of dividends,
dividends (subject to Sections 3(a)(ii) and (iii) hereof) at a rate equal to
______ [the greater of (x) 13% per annum (computed on the basis of a 360 day
year) or (y) the stated rate of interest per annum payable on the Senior
Subordinated Notes due 2008 of Thermadyne Mfg. LLC plus 300 basis points] (the
"DIVIDEND RATE") on the Liquidation Value of each share of Senior Preferred
Stock on and as of the most recent Dividend Payment Date (as defined below). In
the event the Corporation is unable or shall fail to discharge its obligation to
redeem all

                                                                          Page 5

outstanding shares of Senior Preferred Stock pursuant to paragraph 5(c) or 5(d)
hereof, the Dividend Rate shall increase by .25 percent per quarter (each, a
"DEFAULT DIVIDEND") for each quarter or portion thereof following the date on
which such redemption was required to be made until cured, provided that the
aggregate increase shall not exceed 5%. Such dividends shall be payable in the
manner set forth below in Sections 3(a)(ii) and (iii) quarterly on March 31,
June 30, September 30, and December 31 of each year (unless such day is not a
business day, in which event on the next succeeding business day) (each of such
dates being a "DIVIDEND PAYMENT DATE" and each such quarterly period being a
"DIVIDEND PERIOD"). Such dividends shall be cumulative from the date of issue,
whether or not in any Dividend Period or Periods there shall be funds of the
Corporation legally available for the payment of such dividends.

                  (ii) Prior to the fifth anniversary of the issuance of the
                  Senior Preferred Stock (the "CASH PAY DATE"), dividends shall
                  not be payable in cash to holders of shares of Senior
                  Preferred Stock but shall, subject to Section 3(b) hereof,
                  accrete to the Liquidation Value in accordance with Section
                  4(a) hereof.

                   (iii) Following the Cash Pay Date, each such dividend shall
                  be payable in cash on the Liquidation Value per share of the
                  Senior Preferred Stock, in equal quarterly amounts (to which
                  the Default Dividend, if any, shall be added), to the holders
                  of record of shares of the Senior Preferred Stock, as they
                  appear on the stock records of the Corporation at the close of
                  business on such record dates, not more than 60 days or less
                  than 10 days preceding the payment dates thereof, as shall be
                  fixed by the Board of Directors. Accrued and unpaid dividends
                  for any past Dividend Periods may be declared and paid at any
                  time, without reference to any Dividend Payment Date, to
                  holders of record on such date, not more than 45 days
                  preceding the payment date thereof, as may be fixed by the
                  Board of Directors.

         (b) At the written request of the holders of a majority of the shares
of Senior Preferred Stock, the Corporation shall, commencing on the first
Dividend Payment Date after such request and ending on the Cash Pay Date, be
required to pay all dividends on shares of Senior Preferred Stock by the
issuance of additional shares of Senior Preferred Stock ("ADDITIONAL SHARES").
The Additional Shares shall be identical to all other shares of Senior Preferred
Stock, except as set forth in Section 4. For the purposes of determining the
number of Additional Shares to be issued as dividends pursuant to this Paragraph
(b), such Additional Shares shall be valued at their Applicable Liquidation
Value as provided in Section 4(c).

         (c) Holders of shares of Senior Preferred Stock shall not be entitled
to any dividends, whether payable in cash, property or stock, in excess of the
cumulative dividends, as herein provided, on the Senior Preferred Stock. Except

<PAGE>   6
                                                                          Page 6


as provided in this Section 3, no interest, or sum of money in lieu of interest,
shall be payable in respect of any dividend payment or payments on the Senior
Preferred Stock that may be in arrears.

         (d) So long as any shares of the Senior Preferred Stock are
outstanding, no dividends, except as described in the next succeeding sentence,
shall be declared or paid or set apart for payment on Parity Securities, for any
period unless (to the extent such dividends are payable in cash) full cumulative
dividends have been or contemporaneously are declared and paid or declared and a
sum sufficient for the payment thereof set apart for such payment on the Senior
Preferred Stock for all Dividend Periods terminating on or prior to the date of
payment of the dividend on such class or series of Parity Securities. When (to
the extent such dividends are payable in cash) dividends are not paid in full or
a sum sufficient for such payment is not set apart, as aforesaid, all dividends
declared upon shares of the Senior Preferred Stock and all dividends declared
upon any other class or series of Parity Securities shall (in each case, to the
extent payable in cash) be declared ratably in proportion to the respective
amounts of dividends accumulated and unpaid on the Senior Preferred Stock and
accumulated and unpaid on such Parity Securities.

         (e) So long as any shares of the Senior Preferred Stock are
outstanding, no dividends (other than dividends or distributions paid in shares
of, or options, warrants or rights to subscribe for or purchase shares of,
Junior Securities) shall be declared or paid or set apart for payment or other
distribution declared or made upon Junior Securities, nor shall any Junior
Securities be redeemed, purchased or otherwise acquired (other than a
redemption, purchase or other acquisition of shares of Common Stock made for
purposes of an employee incentive or benefit plan of the Corporation or any
subsidiary) (all such dividends, distributions, redemptions or purchases being
hereinafter referred to as a "JUNIOR SECURITIES DISTRIBUTION") for any
consideration (or any moneys be paid to or made available for a sinking fund for
the redemption of any shares of any such stock) by the Corporation, directly or
indirectly (except by conversion into or exchange for Junior Securities), unless
in each case (i) the full cumulative dividends on all outstanding shares of the
Senior Preferred Stock and any other Parity Securities shall (to the extent
payable in cash) have been paid or set apart for payment for all past Dividend
Periods with respect to the Senior Preferred Stock and all past dividend periods
with respect to such Parity Securities and (ii) (to the extent payable in cash)
sufficient funds shall have been paid or set apart for the payment of the
dividend for the current Dividend Period with respect to the Senior Preferred
Stock and the current dividend period with respect to such Parity Securities.

         (4) LIQUIDATION PREFERENCE. (a) In the event of any liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
before any payment or distribution of the assets of the Corporation (whether
capital or surplus) shall be made to or set apart for the holders of Junior
Securities, the holders of the shares of Senior Preferred Stock shall be
entitled to 

<PAGE>   7
                                                                          Page 7

receive an amount equal to the Liquidation Value of such share plus
any accrued and unpaid cash dividends to the date of distribution. "LIQUIDATION
VALUE" on any date means, with respect to (x) any share of Senior Preferred
Stock other than any Additional Shares, the sum of (1) $25.00 per share and (2)
the aggregate of all dividends accreted on such share until the most recent
Dividend Payment Date upon which an accretion to Liquidation Value has occurred
(or if such date is a Dividend Payment Date upon which an accretion to
Liquidation Value has occurred, such date), provided that in the event of an
actual liquidation, dissolution or winding up of the Corporation or the
redemption of any shares of Senior Preferred Stock pursuant to Section 5
hereunder, the amount referred to in (2) shall be calculated by including
dividends accreting to the actual date of such liquidation, dissolution or
winding up or the redemption date, as the case may be, rather than the Dividend
Payment Date referred to above and provided further that in no event will
dividends accrete beyond the earlier of (i) the Cash Pay Date and (ii) the most
recent Dividend Payment Date prior to the Dividend Payment Date on which
dividends on the Senior Preferred Stock are payable in Additional Shares and (y)
any Additional Share, the Applicable Liquidation Value. All accretions to
Liquidation Value will be calculated using compounding on a quarterly basis.
Except as provided in the preceding sentences, holders of shares of Senior
Preferred Stock shall not be entitled to any distribution in the event of
liquidation, dissolution or winding up of the affairs of the Corporation. If,
upon any liquidation, dissolution or winding up of the Corporation, the assets
of the Corporation, or proceeds thereof, distributable among the holders of the
shares of Senior Preferred Stock shall be insufficient to pay in full the
preferential amount aforesaid and liquidating payments on any Parity Securities,
then such assets, or the proceeds thereof, shall be distributed among the
holders of shares of Senior Preferred Stock and any such other Parity Securities
ratably in accordance with the respective amounts that would be payable on such
shares of Senior Preferred Stock and any such other stock if all amounts payable
thereon were paid in full. For the purposes of this Section 4, (i) a
consolidation or merger of the Corporation with one or more corporations, or
(ii) a sale or transfer of all or substantially all of the Corporation's assets,
shall not be deemed to be a liquidation, dissolution or winding up, voluntary or
involuntary, of the Corporation.

         (b) Subject to the rights of the holders of any Parity Securities,
after payment shall have been made in full to the holders of the Senior
Preferred Stock, as provided in this paragraph (4), any other series or class or
classes of Junior Securities shall, subject to the respective terms and
provisions (if any) applying thereto, be entitled to receive any and all assets
remaining to be paid or distributed, and the holders of the Senior Preferred
Stock shall not be entitled to share therein.

         (c) The Applicable Liquidation Value of any Additional Shares shall be
the Liquidation Value of Senior Preferred Stock outstanding immediately prior to
the first Dividend Payment Date occurring after a request for payment in
Additional Shares has been made in accordance with Section 3(b).

         (5) REDEMPTION. (a) Redemption Upon Consummation of Public Offering.
The Corporation may, at its option, to the extent it shall have funds legally
available for such payment, redeem, prior to May 15, 2001, in whole but not in
part, shares of Senior Preferred Stock, at a redemption price per share equal to
113% of the Liquidation Value, in cash, plus accrued and unpaid cash dividends
on such shares to the date fixed for redemption, without interest, provided that
the Corporation shall not redeem any shares of Senior Preferred Stock pursuant
to this Section 5(a) unless (i) prior to such redemption a Public Offering shall
have been consummated, and (ii) the aggregate redemption price of the shares of
Senior Preferred Stock redeemed pursuant to this Section 5(a) does not exceed
the net proceeds received by the Corporation in such Initial Public Offering.

         "PUBLIC OFFERING" shall mean any underwritten public offering of Common
Stock pursuant to an effective registration statement under the Securities Act
of 1933, as amended, and shall, in addition, for the purposes of Section 5(a)
hereof, include any sale, pursuant to such an underwritten registered public
offering, following the Closing Date of any common stock by any affiliate of the
Corporation, the net proceeds of which are contributed or loaned to the
Corporation in such a manner that such proceeds may lawfully be used for the
redemption of the Senior Preferred Stock.

         "CLOSING DATE" shall have the meaning ascribed to such term in the
Investors' Agreement.

         "INVESTORS' AGREEMENT" means the Investors' Agreement dated May __,
1998, among Thermadyne Holdings Corporation, DLJ Merchant Banking Partners II,
L.P., DLJ Merchant Banking Partners II-A, L.P., DLJ Offshore Partners, C.V., DLJ

2003, to the extent the Corporation shall have funds legally available for such

                  (c) Redemption In the Event of a Change of Control. In the
event of a Change of Control, the Corporation shall, to the extent it shall have
funds legally available for such payment, offer to redeem all of the shares of
Senior Preferred Stock then outstanding, and shall redeem the shares of Senior
Preferred Stock of any holder of such shares that shall consent to such
redemption, upon a date no later than 30 days following the Change in Control,
at a redemption price per share equal to 101% of the Liquidation Value, in cash,
plus accrued and unpaid cash dividends thereon to the date fixed for redemption,
without interest.

         "CHANGE OF CONTROL" means such time as: (a) a "person" or "group"
(within the meaning of Sections 13(d) and 14(d)(2) of the Securities Exchange
Act of 1934, as amended), other than any person or group comprised solely of the
Initial Investors, has become the beneficial owner, by way of merger,
consolidation or otherwise, of 30% or more of the voting power of all classes of
voting securities of the Corporation, and such person or group has become the
beneficial owner of a greater percentage of the voting power of all classes of
voting securities of the Corporation than that beneficially owned by the Initial
Investors; or (b) a sale or transfer of all or substantially all of the assets
of the Corporation to any person or group (other than any group consisting
solely of the Initial Investors or their affiliates) has been consummated; or
(c) during any period of two consecutive years, individuals who at the beginning
of such period constituted the Board of Directors of the Corporation (together
with any new directors whose election was approved by a vote of a majority of
the directors then still in office, who either were directors at the beginning
of such period or whose election or nomination for the election was previously
so approved) cease for any reason to constitute a majority of the directors of
the Corporation, then in office.

         "INITIAL INVESTORS" means the Stockholders (determined as of the
issuance of the Preferred Stock) and their Permitted Transferees, each as
defined in the Investors' Agreement.

         (d) Mandatory Redemption. To the extent the Corporation shall have
funds legally available for such payment, on May 15, 2010, if any shares of the
Senior Preferred Stock shall be outstanding, the Corporation shall redeem all

<PAGE>   10
                                                                         Page 10

outstanding shares of the Senior Preferred Stock, at a redemption price equal to
the aggregate Liquidation Value, in cash, together with any accrued and unpaid
cash dividends thereon to the date fixed for redemption, without interest.

         (e) Status of Redeemed Shares. Shares of Senior Preferred Stock which
have been issued and reacquired in any manner, including shares purchased or
redeemed, shall (upon compliance with any applicable provisions of the laws of
the State of Delaware) have the status of authorized and unissued shares of the
class of Preferred Stock undesignated as to series and may be redesignated and
reissued as part of any series of the Preferred Stock; provided that no such
issued and reacquired shares of Senior Preferred Stock shall be reissued or sold
as Senior Preferred Stock.

         (f) Failure to Redeem. If the Corporation is unable or shall fail to
discharge its obligation to redeem all outstanding shares of Senior Preferred
Stock pursuant to paragraph (5)(c) or 5(d) (each, a "MANDATORY REDEMPTION
OBLIGATION"), such Mandatory Redemption Obligation shall be discharged as soon
as the Corporation is able to discharge such Mandatory Redemption Obligation. If
and so long as any Mandatory Redemption Obligation with respect to the Senior
Preferred Stock shall not be fully discharged, the Corporation shall not (i)
directly or indirectly, redeem, purchase, or otherwise acquire any Parity
Security or discharge any mandatory or optional redemption, sinking fund or
other similar obligation in respect of any Parity Securities (except in
connection with a redemption, sinking fund or other similar obligation to be
satisfied pro rata with the Senior Preferred Stock) or (ii) in accordance with
paragraph 3(e), declare or make any Junior Securities Distribution, or, directly
or indirectly, discharge any mandatory or optional redemption, sinking fund or
other similar obligation in respect of the Junior Securities.

         (g) Failure to Pay Dividends. Notwithstanding the foregoing provisions
of this paragraph (5), unless full cumulative cash dividends (whether or not
declared) on all outstanding shares of Senior Preferred Stock shall have been
paid or contemporaneously are declared and paid or set apart for payment for all
dividend periods terminating on or prior to the applicable redemption date, none
of the shares of Senior Preferred Stock shall be redeemed, and no sum shall be
set aside for such redemption, unless shares of Senior Preferred Stock are
redeemed pro rata.

         (6) PROCEDURE FOR REDEMPTION. (a) In the event the Corporation shall
redeem shares of Senior Preferred Stock pursuant to Sections 5(a), (b) or (d),
notice of such redemption shall be given by first class mail, postage prepaid,
mailed not less than 30 days nor more than 60 days prior to the redemption date,
to each holder of record of the shares to be redeemed at such holder's address
as the same appears on the stock register of the Corporation; provided that
neither the failure to give such notice nor any defect therein shall affect the
validity of the giving of notice for the redemption of any share of Senior
Preferred Stock to be redeemed except as to the holder to whom the Corporation
has 

<PAGE>   11
                                                                         Page 11

failed to give said notice or except as to the holder whose notice was
defective. Each such notice shall state: (i) the redemption date; (ii) the
number of shares of Senior Preferred Stock to be redeemed; (iii) the redemption
price; (iv) the place or places where certificates for such shares are to be
surrendered for payment of the redemption price; and (v) that dividends on the
shares to be redeemed will cease to accrue on such redemption date.

         (b) In the case of any redemption pursuant to Sections 5(a), (b) or (d)
hereof, notice having been mailed as provided in Section 6(a) hereof, from and
after the redemption date (unless default shall be made by the Corporation in
providing money for the payment of the redemption price of the shares called for
redemption), dividends on the shares of Senior Preferred Stock so called for
redemption shall cease to accrue, and all rights of the holders thereof as
stockholders of the Corporation (except the right to receive from the
Corporation the redemption price) shall cease. Upon surrender in accordance with
said notice of the certificates for any shares so redeemed (properly endorsed or
assigned for transfer, if the Board of Directors of the Corporation shall so
require and the notice shall so state), such share shall be redeemed by the
Corporation at the redemption price aforesaid. In case fewer than all the shares
represented by any such certificate are redeemed, a new certificate shall be
issued representing the unredeemed shares without cost to the holder thereof.

         (c) In the case of a redemption pursuant to Section 5(c) hereof, notice
of such redemption shall be given by first class mail, postage prepaid, mailed
not more than 10 days following the occurrence of the Change of Control and not
less than 20 days prior to the redemption date, to each holder of record of the
shares to be redeemed at such holder's address as the same appears on the stock
register of the Corporation; provided that neither the failure to give such
notice nor any defect therein shall affect the validity of the giving of notice
for the redemption of any share of Senior Preferred Stock to be redeemed except
as to the holder to whom the Corporation has failed to give said notice or
except as to the holder whose notice was defective. Each such notice shall
state: (i) that a Change of Control has occurred; (ii) the redemption date;
(iii) the redemption price; (iv) that such holder may elect to cause the
Corporation to redeem all or any of the shares of Senior Preferred Stock held by
such holder; (v) the place or places where certificates for such shares are to
be surrendered for payment of the redemption price; and (vi) that dividends on
the shares the holder elects to cause the Corporation to redeem will cease to
accrue on such redemption date.

         Upon receipt of such notice, the holder shall, within 20 days of
receipt thereof, return such notice to the Corporation indicating the number of
shares of Senior Preferred Stock such holder shall elect to cause the
Corporation to redeem, if any.

         (d) In the case of a redemption pursuant to Section 5(c) hereof, notice
having been mailed as provided in Section 6(c) hereof, from and after the
redemption date (unless default shall be made by the Corporation in providing

<PAGE>   12
                                                                         Page 12

money for the payment of the redemption price of the shares called for
redemption), dividends on such shares of Senior Preferred Stock as the holder
elects to cause the Corporation to redeem shall cease to accrue, and all rights
of the holders thereof as stockholders of the Corporation (except the right to
receive from the Corporation the redemption price) shall cease. Upon surrender
in accordance with said notice of the certificates for any shares so redeemed
(properly endorsed or assigned for transfer, if the Board of Directors of the
Corporation shall so require and the notice shall so state), such share shall be
redeemed by the Corporation at the redemption price aforesaid. In case fewer
than all the shares represented by any such certificate are redeemed, a new
certificate shall be issued representing the unredeemed shares without cost to
the holder thereof.

         (7) EXCHANGE. (a) Subject to the provisions of this paragraph (7) the
Corporation may, at its option, at any time and from time to time on any
Dividend Payment Date, exchange, to the extent it is legally permitted to do so,
all, but not less than all, outstanding shares (and fractional shares) of Senior
Preferred Stock, for Exchange Debentures, provided that (i) on or prior to the
date of exchange the Corporation shall have paid to or declared and set aside
for payment to the holders of outstanding shares of Senior Preferred Stock all
accrued and unpaid cash dividends on shares of Senior Preferred Stock through
the exchange date in accordance with the next succeeding paragraph; (ii) no
event of default under the indenture (as defined in such indenture) governing
the Exchange Debentures shall have occurred and be continuing; and (iii) no
shares of Senior Preferred Stock are held on such date by the DLJMB Funds or any
of their Affiliates, or any of their Permitted Transferees. The principal amount
of Exchange Debentures deliverable upon exchange of a share of Senior Preferred
Stock, adjusted as hereinafter provided, shall be determined in accordance with
the Exchange Ratio (as defined below).

         Cash dividends on any shares of Senior Preferred Stock exchanged for
Exchange Debentures which have accrued but have not been paid as of the date of
exchange shall be paid in cash. In no event shall the Corporation issue Exchange
Debentures in denominations other than $1,000 or in an integral multiple
thereof. Cash will be paid in lieu of any such fraction of an Exchange Debenture
which would otherwise have been issued (which shall be determined with respect
to the aggregate principal amount of Exchange Debentures to be issued to a
holder upon any such exchange). Interest will accrue on the Exchange Debentures
from the date of exchange.

         Prior to effecting any exchange hereunder, the Corporation shall
appoint a trustee to serve in the capacity contemplated by an indenture between
the Corporation and such trustee, containing customary terms and conditions.

         The EXCHANGE RATIO shall be, as of any Dividend Payment Date, $1.00 (or
fraction thereof) of principal amount of Exchange Debenture for each $1.00 of
(i) Liquidation Value plus (ii) accrued and unpaid cash dividends, if any, per

<PAGE>   13
                                                                         Page 13

share of Senior Preferred Stock held by a holder on the applicable exchange
date.

         "AFFILIATES" shall have the meaning ascribed such term in the
Investors' Agreement.

         "EXCHANGE DEBENTURES" means 13% Subordinated Exchange Debentures due
2010 of the Corporation, to be issued pursuant to an indenture between the
Corporation and a trustee, containing customary terms and conditions, in
accordance with the Term Sheet attached as Exhibit A hereto.

         "PERMITTED TRANSFEREES" shall have the meaning ascribed to such term in
the Investors' Agreement.

                  (b) Procedure for Exchange. (i) In the event the Corporation
shall exchange shares of Senior Preferred Stock, notice of such exchange shall
be given by first class mail, postage prepaid, mailed not less than 30 days nor
more than 60 days prior to the exchange date, to each holder of record of the
shares to be exchanged at such holder's address as the same appears on the stock
register of the Corporation; provided that neither the failure to give such
notice nor any defect therein shall affect the validity of the giving of notice
for the exchange of any share of Senior Preferred Stock to be exchanged except
as to the holder to whom the Corporation has failed to give said notice or
except as to the holder whose notice was defective. Each such notice shall
state: (A) the exchange date; (B) the number of shares of Senior Preferred Stock
to be exchanged; (C) the Exchange Ratio; (D) the place or places where
certificates for such shares are to be exchanged for notes evidencing the
Exchange Debentures to be received by the exchanging holder; and (E) that
dividends on the shares to be exchanged will cease to accrue on such exchange
date.

                   (ii) Prior to giving notice of intention to exchange, the
                  Corporation shall execute and deliver with a bank or trust
                  company selected by the Corporation an indenture containing
                  customary terms and conditions. The Corporation will cause the
                  Exchange Debentures to be authenticated on the Dividend
                  Payment Date on which the exchange is effective, and will pay
                  interest on the Exchange Debentures at the rate and on the
                  dates specified in such indenture from the exchange date.

                           The Corporation will not give notice of its intention
                  to exchange under paragraph 6(b)(i) hereof unless it shall
                  file at the place or places (including a place in the Borough
                  of Manhattan, The City of New York) maintained for such
                  purpose an opinion of counsel (who may be an employee of the
                  Corporation) to the effect that (i) the indenture has been
                  duly authorized, executed and delivered by the Corporation,
                  has been duly qualified under the Trust Indenture Act of 1939
                  (or that such qualification is not

                                                                         Page 14

                  necessary) and constitutes a valid and binding instrument
                  enforceable against the Corporation in accordance with its
                  terms (subject, as to enforcement, to bankruptcy, insolvency,
                  reorganization and other laws of general applicability
                  relating to or affecting creditors' rights and to general
                  equity principles, and subject to such other qualifications as
                  are then customarily contained in opinions of counsel
                  experienced in such matters), (ii) the Exchange Debentures
                  have been duly authorized and, when executed and authenticated
                  in accordance with the provisions of the indenture and
                  delivered in exchange for the shares of Preferred Stock, will
                  constitute valid and binding obligations of the Corporation
                  entitled to the benefits of the indenture (subject as
                  aforesaid), (iii) neither the execution nor delivery of the
                  indenture or the Exchange Debentures nor compliance with the
                  terms, conditions or provisions of such instruments will
                  result in a breach or violation of any of the terms or
                  provisions of, or constitute a default under, any indenture,
                  mortgage, deed of trust or agreement or instrument, known to
                  such counsel, to which the Corporation or any of its
                  subsidiaries is a party or by which it or any of them is
                  bound, or any decree, judgment, order, rule or regulation,
                  known to such counsel, of any court or governmental agency or
                  body having jurisdiction over the Corporation and such
                  subsidiaries or any of their properties, (iv) the Exchange
                  Debentures have been duly registered for such exchange with
                  the Securities and Exchange Commission under a registration
                  statement that has become effective under the Securities Act
                  of 1933 (the "Act") or that the exchange of the Exchange
                  Debentures for the shares of Senior Preferred Stock is exempt
                  from registration under the Act, and (v) the Corporation has
                  sufficient legally available funds for such exchange such that
                  such exchange is permitted under applicable law.

                   (iii) Notice having been mailed as aforesaid, from and after
                  the exchange date (unless default shall be made by the
                  Corporation in issuing Exchange Debentures in exchange for the
                  shares called for exchange), dividends on the shares of Senior
                  Preferred Stock so called for exchange shall cease to accrue,
                  and all rights of the holders thereof as stockholders of the
                  Corporation (except the right to receive from the Corporation
                  the Exchange Debentures and any rights such holder, upon the
                  exchange, may have as a holder of the Exchange Debenture)
                  shall cease. Upon surrender in accordance with said notice of
                  the certificates for any shares so exchanged (properly
                  endorsed or assigned for transfer, if the Board of Directors
                  of the Corporation shall so require and the notice shall so
                  state), such share shall be exchanged by the Corporation for
                  the Exchange Debentures at the Exchange Ratio. In case fewer
                  than all the shares represented by any such certificate are
                  exchanged, a

                                                                         Page 15


                  new certificate shall be issued representing the unexchanged
                  shares without cost to the holder thereof.

                  (iv) Each exchange shall be deemed to have been effected
                  immediately after the close of business on the relevant
                  Dividend Payment Date, and the person in whose name or names
                  any Exchange Debentures shall be issuable upon such exchange
                  shall be deemed to have become the holder of record of the
                  Exchange Debentures represented thereby at such time on such
                  Dividend Payment Date.

                  (v) Prior to the delivery of any securities which the
                  Corporation shall be obligated to deliver upon exchange of the
                  Senior Preferred Stock, the Corporation shall comply with all
                  applicable federal and state laws and regulations which
                  require action to be taken by the Corporation.

         (c) The Corporation will pay any and all documentary stamp or similar
issue or transfer taxes payable in respect of the issue or delivery of notes
evidencing Exchange Debentures on exchange of the Senior Preferred Stock
pursuant hereto; provided that the Corporation shall not be required to pay any
tax which may be payable in respect of any transfer involved in the issue or
delivery of Exchange Debentures in a name other than that of the holder of the
Senior Preferred Stock to be exchanged and no such issue or delivery shall be
made unless and until the person requesting such issue or delivery has paid to
the Corporation the amount of any such tax or has established, to the
satisfaction of the Corporation, that such tax has been paid.

                  (8) VOTING RIGHTS. (a) The holders of record of shares of
Senior Preferred Stock shall not be entitled to any voting rights except as
hereinafter provided in this paragraph (8), as otherwise provided by law or as
provided in the Investors' Agreement.

                  (b) If and whenever (i) four consecutive or six quarterly cash
dividends payable on the Senior Preferred Stock have not been paid in full, (ii)
for any reason (including the reason that funds are not legally available for a
redemption), the Corporation shall have failed to discharge any Mandatory
Redemption Obligation (including a redemption in the Event of a Change of
Control pursuant to Section 5(c) hereof), (iii) the Corporation shall have
failed to provide the notice required by Section 6(c) hereof within the time
period specified in such section or (iv) the Corporation shall have failed to
comply with Sections 3(d), 3(e) or 8(c) hereof, (1) the number of directors then
constituting the Board of Directors shall be increased by two and the holders of
a majority of the outstanding shares of Senior Preferred Stock, together with
the holders of shares of every other series of preferred stock upon which like
rights have been conferred and are exercisable (resulting from either the
failure to pay dividends or the failure to redeem) (any such series is referred
to as the "PREFERRED

                                                                         Page 16

SHARES"), voting as a single class regardless of series, shall be entitled to
elect the two additional directors to serve on the Board of Directors at any
annual meeting of stockholders or special meeting held in place thereof, or at a
special meeting of the holders of the Senior Preferred Stock and the Preferred
Shares called as hereinafter provided. Whenever (i) all arrears in cash
dividends on the Senior Preferred Stock and the Preferred Shares then
outstanding shall have been paid and cash dividends thereon for the current
quarterly dividend period shall have been paid or declared and set apart for
payment, (ii) the Corporation shall have fulfilled its Mandatory Redemption
Obligation, (iii) fulfilled its obligation to provide notice as specified in
subsection (b)(iii) hereof, or (iv) the Corporation shall have complied with
Sections 3(d), 3(e), or 8(c) hereof, as the case may be, then the right of the
holders of the Senior Preferred Stock to elect such additional two directors
shall cease (but subject always to the same provisions for the vesting of such
voting rights in the case of any similar future (i) arrearage in six consecutive
quarterly cash dividends, (ii) failure to fulfill any Mandatory Redemption
Obligation, (iii) failure to fulfill the obligation to provide the notice
required by Section 6(d) hereof within the time period specified in such section
or (iv) failure to comply with Sections 3(d), 3(e), or 8(c)) and the terms of
office of all persons elected as directors by the holders of the Senior
Preferred Stock shall forthwith terminate and the number of the Board of
Directors shall be reduced accordingly. At any time after such voting power
shall have been so vested in the holders of shares of Senior Preferred Stock and
the Preferred Shares, the secretary of the Corporation may, and upon the written
request of any holder of Senior Preferred Stock (addressed to the secretary at
the principal office of the Corporation) shall, call a special meeting of the
holders of the Senior Preferred Stock and of the Preferred Shares for the
election of the two directors to be elected by them as herein provided, such
call to be made by notice similar to that provided in the Bylaws of the
Corporation for a special meeting of the stockholders or as required by law. If
any such special meeting required to be called as above provided shall not be
called by the secretary within 20 days after receipt of any such request, then
any holder of shares of Senior Preferred Stock may call such meeting, upon the
notice above provided, and for that purpose shall have access to the stock books
of the Corporation. The directors elected at any such special meeting shall hold
office until the next annual meeting of the stockholders or special meeting held
in lieu thereof if such office shall not have previously terminated as above
provided. If any vacancy shall occur among the directors elected by the holders
of the Senior Preferred Stock and the Preferred Shares, a successor shall be
elected by the Board of Directors, upon the nomination of the then-remaining
director elected by the holders of the Senior Preferred Stock and the Preferred
Shares or the successor of such remaining director, to serve until the next
annual meeting of the stockholders or special meeting held in place thereof if
such office shall not have previously terminated as provided above.

         (c) Without the written consent of a majority of the outstanding shares
of Senior Preferred Stock or the vote of holders of a majority of the
outstanding shares of Senior Preferred Stock at a meeting of the holders of
Senior Preferred Stock called for such purpose, the Corporation will not (i)
amend, alter or repeal any provision of the Certificate of Incorporation (by
merger or otherwise) so as to adversely affect the preferences, rights or powers
of the Senior Preferred Stock; provided that any such amendment that decreases
the dividend payable on or the Liquidation Value of the Senior Preferred Stock
shall require the affirmative vote of holders of each share of Senior Preferred
Stock at a meeting of holders of Senior Preferred Stock called for such purpose
or written consent of the holder of each share of Senior Preferred

                                                                         Page 17


Stock; or (ii) create, authorize or issue any class of stock ranking prior to,
or on a parity with, the Senior Preferred Stock with respect to dividends or
upon liquidation, dissolution, winding up or otherwise, or increase the
authorized number of shares of any such class or series, or reclassify any
authorized stock of the Corporation into any such prior or parity shares or
create, authorize or issue any obligation or security convertible into or
evidencing the right to purchase any such prior or parity shares, except that
the Corporation may, without such approval, create authorize and issue Parity
Securities for the purpose of utilizing the proceeds from the issuance of such
Parity Securities for the redemption or repurchase of all outstanding shares of
Senior Preferred Stock in accordance with the terms hereof or of the Investors'
Agreement.

         (d) In exercising the voting rights set forth in this paragraph (8),
each share of Senior Preferred Stock shall have one vote per share, except that
when any other series of preferred stock shall have the right to vote with the
Senior Preferred Stock as a single class on any matter, then the Senior
Preferred Stock and such other series shall have with respect to such matters
one vote per $25 of Liquidation Value or other liquidation preference. Except as
otherwise required by applicable law or as set forth herein, the shares of
Senior Preferred Stock shall not have any relative, participating, optional or
other special voting rights and powers and the consent of the holders thereof
shall not be required for the taking of any corporate action.

         (9) REPORTS. So long as any of the Senior Preferred Stock is
outstanding, the Corporation will furnish the holders thereof with the quarterly
and annual financial reports that the Corporation is required to file with the
Securities and Exchange Commission pursuant to Section 13 or Section 15(d) of
the Securities Exchange Act of 1934 or, in the event the Corporation is not
required to file such reports, reports containing the same information as would
be required in such reports.

         (10) GENERAL PROVISIONS. (a) The term "PERSON" as used herein means any
corporation, limited liability company, partnership, trust, organization,

               (d) Each holder of Senior Preferred Stock, by acceptance thereof,
         acknowledges and agrees that payments of dividends, interest, premium
         and principal on, and exchange, redemption and repurchase of, such
         securities by the Corporation are subject to restrictions on the
         Corporation contained in certain credit and financing agreements.

               FIFTH: No contract or transaction between the Corporation and one
         or more of its directors, officers, or stockholders or between the
         Corporation and any person (as used herein "person" means any other
         corporation, partnership, association, firm, trust, joint venture,
         political subdivision, or instrumentality) or other organization in
         which one or more of its directors, officers, or stockholders are
         directors, officers or stockholders, or have a financial interest,
         shall be void or voidable solely for this reason, or solely because the
         director or officer is present at or participates in the meeting of the
         board or committee which authorizes the contract or transaction, or
         solely because his, her, or their votes are counted for such purpose,
         if: (i) the material facts as to his or her relationship or interest
         and as to the contract or transaction are disclosed or are known to the
         board of directors or the committee, and the board of directors or
         committee in good faith authorizes the contract or transaction by the
         affirmative votes of a

                                                                         Page 18

         majority of the disinterested directors, even though the disinterested
         directors be less than a quorum; or (ii) the material facts as to his
         or her relationship or interest and as to the contract or transaction
         are disclosed or are known to the stockholders entitled to vote
         thereon, and the contract or transaction is specifically approved in
         good faith by vote of the stockholders; or (iii) the contract or
         transaction is fair as to the Corporation as of the time it is
         authorized, approved, or ratified by the board of directors, a
         committee thereof (to the extent permitted by applicable law), or the
         stockholders. Common or interested directors may be counted in
         determining the presence of a quorum at a meeting of the board of
         directors or of a committee which authorizes the contract or
         transaction.

               SIXTH: The Board of Directors shall have the power to adopt,
         amend or repeal the bylaws of the Corporation.

               SEVENTH: Election of directors need not be by written ballot

               EIGHTH: A director of the Corporation shall not be personally
         liable to the Corporation or its stockholders for monetary damages for
         breach of fiduciary duty as a director, except for liability (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 knowing violation of law, (iii) under
         Section 174 of the Delaware Law, or (iv) for any transaction from which
         the director derived an improper personal benefit. Any repeal or
         amendment of this Article EIGHTH by the stockholders of the Corporation
         shall be prospective only, and shall not adversely affect any
         limitation on the personal liability of a director of the Corporation
         arising from an act or omission occurring prior to the time of such
         repeal or amendment. In addition to the circumstances in which a
         director of the Corporation is not personally liable as set forth in
         the foregoing provisions of this Article EIGHTH, a director shall not
         be liable to the Corporation or its stockholders to such further extent
         as permitted by any law hereafter enacted, including without limitation
         any subsequent amendment to the Delaware Law.

               NINTH: (1) A director of the Corporation shall not be liable to

         such person) who was or is a party or is threatened to be made a party
         to, or is involved in any threatened, pending or completed action, suit
         or proceeding, whether civil, criminal, administrative or
         investigative, by reason of the fact that such person is or was a
         director or officer of the Corporation or is or was serving at the
         request of the Corporation as a director or officer of another
         corporation, partnership, joint venture, trust or other enterprise,
         shall be indemnified and held harmless by the Corporation to the
         fullest extent permitted by Delaware Law.

                                                                         Page 19

         The right to indemnification conferred in this Article NINTH
         shall also include the right to be paid by the Corporation the expenses
         incurred in connection with any such proceeding in advance of its final
         disposition to the fullest extent authorized by Delaware Law. The right
         to indemnification conferred in this Article NINTH shall be a contract
         right.

               (b) The Corporation may, by action of its Board of Directors,
         provide indemnification to such of the officers, employees and agents
         of the Corporation to such extent and to such effect as the Board of
         Directors shall determine to be appropriate and authorized by Delaware
         Law.

               (3) The Corporation shall have power to purchase and maintain
         insurance on behalf of any person who is or was a director, officer,
         employee or agent of the Corporation, or is or was serving at the
         request of the Corporation as a director, officer, employee or agent of
         another corporation, partnership, joint venture, trust or other
         enterprise against any expense, liability or loss incurred by such
         person in any such capacity or arising out of his status as such,
         whether or not the Corporation would have the power to indemnify him
         against such liability under Delaware Law.

               (4) The rights and authority conferred in this Article NINTH
         shall not be exclusive of any other right which any person may
         otherwise have or hereafter acquire.

               (5) Neither the amendment nor repeal of this Article NINTH, nor
         the adoption of any provision of this Certificate of Incorporation or
         the bylaws of the Corporation, nor, to the fullest extent permitted by
         Delaware Law, any modification of law, shall eliminate or reduce the
         effect of this Article NINTH in respect of any acts or omissions
         occurring prior to such amendment, repeal, adoption or modification.

               TENTH: The Corporation expressly elects not to be governed by
         Section 203 of the Delaware Law.

               ELEVENTH: The Corporation reserves the right to amend this
         Certificate of Incorporation in any manner permitted by Delaware Law
         and, with the sole exception of those rights and powers conferred under
         the above Article NINTH, all rights and powers conferred herein on
         stockholders, directors and officers, if any, are subject to this
         reserved power.

         as the same exists or may hereafter be amended (the "Delaware Law").

                 FOURTH: The total number of shares of stock which the
         Corporation shall have authority to issue is 45,000,000, consisting of

         $0.01 per share (the "PREFERRED STOCK"), of which 2,000,000 shares
         have been designated 13% Senior Exchangeable Preferred Stock (the

                 The designations and the powers and preferences, rights,
         qualifications, limitations and restrictions of the Common Stock and

         payable in cash, stock, or otherwise.





                                       2
<PAGE>   3
                 Upon any liquidation, dissolution, or winding up of the
         Corporation, whether voluntary or involuntary, and after the holders
         of any bonds, debentures, or other obligations of the Corporation
         shall have been paid in full the amounts to which they shall be
         entitled (if any), or a sum sufficient for such payment in full shall
         have been set aside, the remaining net assets of the Corporation shall
         be distributed pro rata to the holders of the Common Stock in
         accordance with their respective rights and interests, to the
         exclusion of the holders of any bonds, debentures, or other
         obligations of the Corporation.

                 The Corporation may issue shares of its Common Stock from time
         to time for such consideration (in any form, but not less in value
         than the par value thereof) as may be fixed by the board of directors
         of the Corporation, which is expressly authorized to fix the same in
         its absolute and uncontrolled discretion subject to the foregoing
         conditions. Shares so issued for which the consideration shall have
         been paid or delivered to the Corporation shall be deemed fully paid
         stock and shall not be liable to any further call or assessment
         thereon, and the holders of such shares shall not be liable for any
         further payments in respect of such shares.  The Corporation shall
         also have authority to create and issue rights and options entitling
         their holders to purchase or otherwise acquire shares of Common Stock
         and such rights and options shall be evidenced by instrument(s)
         approved by the board of directors of the Corporation. The board of
         directors of the Corporation shall be empowered to set the exercise
         price, duration, times for exercise, and other terms of such options
         or rights; provided, however, that the consideration to be received
         (which may be in any form) for any shares of Common Stock subject
         thereto shall have a value not less than the par value thereof.

                 B.       Provisions Relating to the Preferred Stock

                 The Board of Directors is hereby empowered to authorize by
         resolution or resolutions from time to time the issuance of one or
         more classes or series of Preferred Stock and to fix the designations,
         powers, preferences and relative, participating, optional or other
         rights, if any, and the qualifications, limitations or restrictions
         thereof, if any, with respect to each such class or series of
         Preferred Stock and the number of shares constituting each such class
         or series, and to increase or decrease the number of shares of





                                       3
<PAGE>   4
         any such class or series to the extent permitted by the Delaware Law.

                 C.       Provisions Relating to the Senior Preferred Stock

                 (1) NUMBER AND DESIGNATION.  2,000,000 shares of the Preferred
         Stock of the Corporation shall be designated as 13% Senior
         Exchangeable Preferred Stock.

                 (2) RANK. The Senior Preferred Stock shall, with respect to
         dividend rights and rights on liquidation, dissolution and winding up,
         rank prior to all classes of or series of common stock of the
         Corporation, including the Common Stock, and each other class of
         capital stock of the Corporation, the terms of which provide that such
         class shall rank junior to the Senior Preferred Stock or the terms of
         which do not specify any rank relative to the Senior Preferred Stock.
         All equity securities of the Corporation to which the Senior Preferred
         Stock ranks prior (whether with respect to dividends or upon
         liquidation, dissolution, winding up or otherwise), including the
         Common Stock, are collectively referred to herein as the "JUNIOR
         SECURITIES." All equity securities of the Corporation with which the
         Senior Preferred Stock ranks on a parity (whether with respect to
         dividends or upon liquidation, dissolution or winding up) are
         collectively referred to herein as the "PARITY SECURITIES." The
         respective definitions of Junior Securities and Parity Securities
         shall also include any rights or options exercisable for or
         convertible into any of the Junior Securities and Parity Securities,
         as the case may be. The Senior Preferred Stock shall be subject to the
         creation of Junior Securities.

                 (3) DIVIDENDS. (a)  (i) The holders of shares of Senior
         Preferred Stock shall be entitled to receive, when, as and if declared
         by the Board of Directors, out of funds legally available for the
         payment of dividends, dividends (subject to Sections 3(a)(ii) and
         (iii) hereof) at a rate equal to 13% per annum (computed on the basis
         of a 360 day year) (the "DIVIDEND RATE") on the Liquidation Value of
         each share of Senior Preferred Stock on and as of the most recent
         Dividend Payment Date (as defined below). In the event the Corporation
         is unable or shall fail to discharge its obligation to redeem all
         outstanding shares of Senior Preferred Stock pursuant to paragraph
         5(c) or 5(d) hereof, the Dividend Rate shall increase by .25 percent
         per quarter (each, a "DEFAULT DIVIDEND") for each quarter or portion
         thereof following the date





                                       4
<PAGE>   5
         on which such redemption was required to be made until cured, provided
         that the aggregate increase shall not exceed 5%. Such dividends shall
         be payable in the manner set forth below in Sections 3(a)(ii) and
         (iii) quarterly on March 31, June 30, September 30, and December 31 of
         each year (unless such day is not a business day, in which event on
         the next succeeding business day) (each of such dates being a
         "DIVIDEND PAYMENT DATE" and each such quarterly period being a
         "DIVIDEND PERIOD"). Such dividends shall be cumulative from the date
         of issue, whether or not in any Dividend Period or Periods there shall
         be funds of the Corporation legally available for the payment of such
         dividends.

                 (ii) Prior to the fifth anniversary of the issuance of the
                 Senior Preferred Stock (the "CASH PAY DATE"), dividends shall
                 not be payable in cash to holders of shares of Senior
                 Preferred Stock but shall, subject to Section 3(b) hereof,
                 accrete to the Liquidation Value in accordance with Section
                 4(a) hereof.

                 (iii) Following the Cash Pay Date, each such dividend shall be
                 payable in cash on the Liquidation Value per share of the
                 Senior Preferred Stock, in equal quarterly amounts (to which
                 the Default Dividend, if any, shall be added), to the holders
                 of record of shares of the Senior Preferred Stock, as they
                 appear on the stock records of the Corporation at the close of
                 business on such record dates, not more than 60 days or less
                 than 10 days preceding the payment dates thereof, as shall be
                 fixed by the Board of Directors. Accrued and unpaid dividends
                 for any past Dividend Periods may be declared and paid at any
                 time, without reference to any Dividend Payment Date, to
                 holders of record on such date, not more than 45 days
                 preceding the payment date thereof, as may be fixed by the
                 Board of Directors.

                 (b) At the written request of the holders of a majority of the
         shares of Senior Preferred Stock, the Corporation shall, commencing on
         the first Dividend Payment Date after such request and ending on the
         Cash Pay Date, be required to pay all dividends on shares of Senior
         Preferred Stock by the issuance of additional shares of Senior
         Preferred Stock ("ADDITIONAL SHARES"). The Additional Shares shall be
         identical to all other shares of Senior





                                       5
<PAGE>   6
         Preferred Stock, except as set forth in Section 4. For the purposes of
         determining the number of Additional Shares to be issued as dividends
         pursuant to this Paragraph (b), such Additional Shares shall be valued
         at their Applicable Liquidation Value as provided in Section 4(c).

                 (c)  Holders of shares of Senior Preferred Stock shall not be
         entitled to any dividends, whether payable in cash, property or stock,
         in excess of the cumulative dividends, as herein provided, on the
         Senior Preferred Stock. Except as provided in this Section 3, no
         interest, or sum of money in lieu of interest, shall be payable in
         respect of any dividend payment or payments on the Senior Preferred
         Stock that may be in arrears.

                 (d)  So long as any shares of the Senior Preferred Stock are
         outstanding, no dividends, except as described in the next succeeding
         sentence, shall be declared or paid or set apart for payment on Parity
         Securities, for any period unless (to the extent such dividends are
         payable in cash) full cumulative dividends have been or
         contemporaneously are declared and paid or declared and a sum
         sufficient for the payment thereof set apart for such payment on the
         Senior Preferred Stock for all Dividend Periods terminating on or
         prior to the date of payment of the dividend on such class or series
         of Parity Securities. When (to the extent such dividends are payable
         in cash) dividends are not paid in full or a sum sufficient for such
         payment is not set apart, as aforesaid, all dividends declared upon
         shares of the Senior Preferred Stock and all dividends declared upon
         any other class or series of Parity Securities shall (in each case, to
         the extent payable in cash) be declared ratably in proportion to the
         respective amounts of dividends accumulated and unpaid on the Senior
         Preferred Stock and accumulated and unpaid on such Parity Securities.

                 (e)  So long as any shares of the Senior Preferred Stock are
         outstanding, no dividends (other than dividends or distributions paid
         in shares of, or options, warrants or rights to subscribe for or
         purchase shares of, Junior Securities) shall be declared or paid or
         set apart for payment or other distribution declared or made upon
         Junior Securities, nor shall any Junior Securities be redeemed,
         purchased or otherwise acquired (other than a redemption, purchase or
         other acquisition of shares of Common Stock made for purposes of an
         employee incentive or benefit plan of the Corporation or any
         subsidiary) (all such dividends, distributions,





                                       6
<PAGE>   7
         redemptions or purchases being hereinafter referred to as a "JUNIOR
         SECURITIES DISTRIBUTION") for any consideration (or any moneys be paid
         to or made available for a sinking fund for the redemption of any
         shares of any such stock) by the Corporation, directly or indirectly
         (except by conversion into or exchange for Junior Securities), unless
         in each case (i) the full cumulative dividends on all outstanding
         shares of the Senior Preferred Stock and any other Parity Securities
         shall (to the extent payable in cash) have been paid or set apart for
         payment for all past Dividend Periods with respect to the Senior
         Preferred Stock and all past dividend periods with respect to such
         Parity Securities and (ii) (to the extent payable in cash) sufficient
         funds shall have been paid or set apart for the payment of the
         dividend for the current Dividend Period with respect to the Senior
         Preferred Stock and the current dividend period with respect to such
         Parity Securities.

                 (4) LIQUIDATION PREFERENCE. (a)  In the event of any
         liquidation, dissolution or winding up of the Corporation, whether
         voluntary or involuntary, before any payment or distribution of the
         assets of the Corporation (whether capital or surplus) shall be made
         to or set apart for the holders of Junior Securities, the holders of
         the shares of Senior Preferred Stock shall be entitled to receive an
         amount equal to the Liquidation Value of such share plus any accrued
         and unpaid cash dividends to the date of distribution.  "LIQUIDATION
         VALUE" on any date means, with respect to (x) any share of Senior
         Preferred Stock other than any Additional Shares, the sum of (1)
         $25.00 per share and (2) the aggregate of all dividends accreted on
         such share until the most recent Dividend Payment Date upon which an
         accretion to Liquidation Value has occurred (or if such date is a
         Dividend Payment Date upon which an accretion to Liquidation Value has
         occurred, such date), provided that in the event of an actual
         liquidation, dissolution or winding up of the Corporation or the
         redemption of any shares of Senior Preferred Stock pursuant to Section
         5 hereunder,  the amount referred to in (2) shall be calculated by
         including dividends accreting to the actual date of such liquidation,
         dissolution or winding up or the redemption date, as the case may be,
         rather than the Dividend Payment Date referred to above and provided
         further that in no event will dividends accrete beyond the earlier of
         (i) the Cash Pay Date and (ii) the most recent Dividend Payment Date
         prior to the Dividend Payment Date on which dividends on the Senior
         Preferred Stock are payable in Additional Shares and (y) any
         Additional Share, the Applicable Liquidation Value. All accretions





                                       7
<PAGE>   8
         to Liquidation Value will be calculated using compounding on a
         quarterly basis. Except as provided in the preceding sentences,
         holders of shares of Senior Preferred Stock shall not be entitled to
         any distribution in the event of liquidation, dissolution or winding
         up of the affairs of the Corporation. If, upon any liquidation,
         dissolution or winding up of the Corporation, the assets of the
         Corporation, or proceeds thereof, distributable among the holders of
         the shares of Senior Preferred Stock shall be insufficient to pay in
         full the preferential amount aforesaid and liquidating payments on any
         Parity Securities, then such assets, or the proceeds thereof, shall be
         distributed among the holders of shares of Senior Preferred Stock and
         any such other Parity Securities ratably in accordance with the
         respective amounts that would be payable on such shares of Senior
         Preferred Stock and any such other stock if all amounts payable
         thereon were paid in full. For the purposes of this Section 4, (i) a
         consolidation or merger of the Corporation with one or more
         corporations, or (ii) a sale or transfer of all or substantially all
         of the Corporation's assets, shall not be deemed to be a liquidation,
         dissolution or winding up, voluntary or involuntary, of the
         Corporation.

                 (b) Subject to the rights of the holders of any Parity
         Securities, after payment shall have been made in full to the holders
         of the Senior Preferred Stock, as provided in this paragraph (4), any
         other series or class or classes of Junior Securities shall, subject
         to the respective terms and provisions (if any) applying thereto, be
         entitled to receive any and all assets remaining to be paid or
         distributed, and the holders of the Senior Preferred Stock shall not
         be entitled to share therein.

                 (c) The Applicable Liquidation Value of any Additional Shares
         shall be the Liquidation Value of Senior Preferred Stock outstanding
         immediately prior to the first Dividend Payment Date occurring after a
         request for payment in Additional Shares has been made in accordance
         with Section 3(b).

                 (5) REDEMPTION. (a)  Redemption Upon Consummation of Public
         Offering. The Corporation may, at its option, to the extent it shall
         have funds legally available for such payment, redeem, prior to May
         15, 2001, in whole but not in part, shares of Senior Preferred Stock,
         at a redemption price per share equal to 113% of the Liquidation
         Value, in cash, plus accrued and unpaid cash dividends on such shares
         to the date fixed for redemption, without interest,





                                       8
<PAGE>   9
         provided that the Corporation shall not redeem any shares of Senior
         Preferred Stock pursuant to this Section 5(a) unless (i) prior to such
         redemption a Public Offering shall have been consummated, and (ii) the
         aggregate redemption price of the shares of Senior Preferred Stock
         redeemed pursuant to this Section 5(a) does not exceed the net
         proceeds received by the Corporation in such Initial Public Offering.

                 "PUBLIC OFFERING" shall mean any underwritten public offering
         of Common Stock pursuant to an effective registration statement under
         the Securities Act of 1933, as amended, and shall, in addition, for
         the purposes of Section 5(a) hereof, include any sale, pursuant to
         such an underwritten registered public offering, following the Closing
         Date of any common stock by any affiliate of the Corporation, the net
         proceeds of which are contributed or loaned to the Corporation in such
         a manner that such proceeds may lawfully be used for the redemption of
         the Senior Preferred Stock.

                 "CLOSING DATE" shall have the meaning ascribed to such term in
         the Investors' Agreement.

                 "INVESTORS' AGREEMENT" means the Investors' Agreement dated

         (collectively, the "DLJMB Funds"), and certain other stockholders
         listed on the signature pages thereof.

                 (b) Redemption At the Option of the Corporation. On and after
         May 15, 2003, to the extent the Corporation shall have funds legally
         available for such payment, the Corporation may, at its option, redeem
         shares of Senior Preferred Stock, at any time in whole but not in

                 (c) Redemption In the Event of a Change of Control. In the
         event of a Change of Control, the Corporation shall, to the extent it
         shall have funds legally available for such payment, offer to redeem
         all of the shares of Senior Preferred Stock then outstanding, and
         shall redeem the shares of Senior Preferred Stock of any holder of
         such shares that shall consent to such redemption, upon a date no
         later than 30 days following the Change in Control, at a redemption
         price per share equal to 101% of the Liquidation Value, in cash, plus
         accrued and unpaid cash dividends thereon to the date fixed for
         redemption, without interest.

         "group" (within the meaning of Sections 13(d) and 14(d)(2) of the

         beneficial owner, by way of merger, consolidation or otherwise, of 30%
         or more of the voting power of all classes of voting securities of the
         Corporation, and such person or group has become the beneficial owner
         of a greater percentage of the voting power of all classes of voting
         securities of the Corporation than that beneficially owned by the
         Initial Investors; or (b) a sale or transfer of all or substantially
         all of the assets of the Corporation to any person or group (other
         than any group consisting solely of the Initial Investors or their
         affiliates) has been consummated; or (c) during any period of two
         consecutive years, individuals who at the beginning of such period
         constituted the Board of Directors of the Corporation (together with
         any new directors whose election was approved by a vote of a majority
         of the directors then still in office, who either were directors at
         the beginning of such period or whose election or nomination for the
         election was previously so approved) cease for any reason to
         constitute a majority of the directors of the Corporation, then in
         office.

         have funds legally available for such payment, on May 15, 2010, if any
         shares of the Senior Preferred Stock shall be outstanding, the
         Corporation shall redeem all outstanding shares of the Senior
         Preferred Stock, at a redemption price equal to the aggregate
         Liquidation Value, in cash, together with any accrued and unpaid cash
         dividends thereon to the date fixed for redemption, without interest.

                 (e) Status of Redeemed Shares. Shares of Senior Preferred
         Stock which have been issued and reacquired in any manner, including
         shares purchased or redeemed, shall (upon compliance with any
         applicable provisions of the laws of the State of Delaware) have the
         status of authorized and unissued shares of the class of Preferred
         Stock undesignated as to series and may be redesignated and reissued
         as part of any series of the Preferred Stock; provided that no such
         issued and reacquired shares of Senior Preferred Stock shall be
         reissued or sold as Senior Preferred Stock.

                 (f) Failure to Redeem. If the Corporation is unable or shall
         fail to discharge its obligation to redeem all outstanding shares of
         Senior Preferred Stock pursuant to paragraph (5)(c) or 5(d) (each, a
         "MANDATORY REDEMPTION OBLIGATION"), such Mandatory Redemption
         Obligation shall be discharged as soon as the Corporation is able to
         discharge such Mandatory Redemption Obligation. If and so long as any
         Mandatory Redemption Obligation with respect to the Senior Preferred
         Stock shall not be fully discharged, the Corporation shall not (i)
         directly or indirectly, redeem, purchase, or otherwise acquire any
         Parity Security or discharge any mandatory or optional redemption,
         sinking fund or other similar obligation in respect of any Parity
         Securities (except in connection with a redemption, sinking fund or
         other similar obligation to be satisfied pro rata with the Senior
         Preferred Stock) or (ii) in accordance with paragraph 3(e), declare or
         make any Junior Securities Distribution, or, directly or indirectly,

                 (g) Failure to Pay Dividends. Notwithstanding the foregoing
         provisions of this paragraph (5), unless full cumulative cash
         dividends (whether or not declared) on all outstanding shares of
         Senior Preferred Stock shall have been paid or contemporaneously are
         declared and paid or set apart for payment for all dividend periods
         terminating on or prior to the applicable redemption date, none of the
         shares of Senior Preferred Stock shall be redeemed, and no sum shall
         be set aside for such redemption, unless shares of Senior Preferred
         Stock are redeemed pro rata.

                 (6) PROCEDURE FOR REDEMPTION. (a) In the event the Corporation
         shall redeem shares of Senior Preferred Stock pursuant to Sections
         5(a), (b) or (d), notice of such redemption shall be given by first
         class mail, postage prepaid, mailed not less than 30 days nor more
         than 60 days prior to the redemption date, to each holder of record of
         the shares to be redeemed at such holder's address as the same appears
         on the stock register of the Corporation; provided that neither the
         failure to give such notice nor any defect therein shall affect the
         validity of the giving of notice for the redemption of any share of
         Senior Preferred Stock to be redeemed except as to the holder to whom
         the Corporation has failed to give said notice or except as to the
         holder whose notice was defective. Each such notice shall state: (i)
         the redemption date; (ii) the number of shares of Senior Preferred
         Stock to be redeemed; (iii) the redemption price; (iv) the place or
         places where certificates for such shares are to be surrendered for
         payment of the redemption price; and (v) that dividends on the shares
         to be redeemed will cease to accrue on such redemption date.

                 (b)  In the case of any redemption pursuant to Sections 5(a),
         (b) or (d) hereof, notice having been mailed as provided in Section
         6(a) hereof, from and after the redemption date (unless default shall
         be made by the Corporation in providing money for the payment of the
         redemption price of the shares called for redemption), dividends on
         the shares of Senior Preferred Stock so called for redemption shall
         cease to accrue, and all rights of the holders thereof as stockholders
         of the Corporation (except the right to receive from the Corporation
         the redemption price) shall cease. Upon surrender in accordance with
         said notice of the certificates for any shares so redeemed (properly
         endorsed or assigned for transfer, if the Board of Directors of the
         Corporation shall so require and the notice shall so state), such
         share shall be redeemed by the Corporation at the redemption price
         aforesaid. In case fewer than all the shares





                                       12
<PAGE>   13
         represented by any such certificate are redeemed, a new certificate
         shall be issued representing the unredeemed shares without cost to the
         holder thereof.

                 (c)  In the case of a redemption pursuant to Section 5(c)
         hereof, notice of such redemption shall be given by first class mail,
         postage prepaid, mailed not more than 10 days following the occurrence
         of the Change of Control and not less than 20 days prior to the
         redemption date, to each holder of record of the shares to be redeemed
         at such holder's address as the same appears on the stock register of
         the Corporation; provided that neither the failure to give such notice
         nor any defect therein shall affect the validity of the giving of
         notice for the redemption of any share of Senior Preferred Stock to be
         redeemed except as to the holder to whom the Corporation has failed to
         give said notice or except as to the holder whose notice was
         defective. Each such notice shall state: (i) that a Change of Control
         has occurred; (ii) the redemption date; (iii) the redemption price;
         (iv) that such holder may elect to cause the Corporation to redeem all
         or any of the shares of Senior Preferred Stock held by such holder;
         (v) the place or places where certificates for such shares are to be
         surrendered for payment of the redemption price; and (vi) that
         dividends on the shares the holder elects to cause the Corporation to
         redeem will cease to accrue on such redemption date.

                 Upon receipt of such notice, the holder shall, within 20 days
         of receipt thereof, return such notice to the Corporation indicating
         the number of shares of Senior Preferred Stock such holder shall elect
         to cause the Corporation to redeem, if any.

                 (d)  In the case of a redemption pursuant to Section 5(c)
         hereof, notice having been mailed as provided in Section 6(c) hereof,
         from and after the redemption date (unless default shall be made by
         the Corporation in providing money for the payment of the redemption
         price of the shares called for redemption), dividends on such shares
         of Senior Preferred Stock as the holder elects to cause the
         Corporation to redeem shall cease to accrue, and all rights of the
         holders thereof as stockholders of the Corporation (except the right
         to receive from the Corporation the redemption price) shall cease.
         Upon surrender in accordance with said notice of the certificates for
         any shares so redeemed (properly endorsed or assigned for transfer, if
         the Board of Directors of the Corporation shall so require and the
         notice shall so state), such share shall be





                                       13
<PAGE>   14
         redeemed by the Corporation at the redemption price aforesaid. In case
         fewer than all the shares represented by any such certificate are
         redeemed, a new certificate shall be issued representing the
         unredeemed shares without cost to the holder thereof.

                 (7) EXCHANGE. (a) Subject to the provisions of this paragraph
         (7) the Corporation may, at its option, at any time and from time to
         time on any Dividend Payment Date, exchange, to the extent it is
         legally permitted to do so, all, but not less than all, outstanding
         shares (and fractional shares) of Senior Preferred Stock, for Exchange
         Debentures, provided that (i) on or prior to the date of exchange the
         Corporation shall have paid to or declared and set aside for payment
         to the holders of outstanding shares of Senior Preferred Stock all
         accrued and unpaid cash dividends on shares of Senior Preferred Stock
         through the exchange date in accordance with the next succeeding
         paragraph; (ii) no event of default under the indenture (as defined in
         such indenture) governing the Exchange Debentures shall have occurred
         and be continuing; and (iii) no shares of Senior Preferred Stock are
         held on such date by the DLJMB Funds or any of their Affiliates, or
         any of their Permitted Transferees.  The principal amount of Exchange
         Debentures deliverable upon exchange of a share of Senior Preferred
         Stock, adjusted as hereinafter provided, shall be determined in
         accordance with the Exchange Ratio (as defined below).

                 Cash dividends on any shares of Senior Preferred Stock
         exchanged for Exchange Debentures which have accrued but have not been
         paid as of the date of exchange shall be paid in cash.  In no event
         shall the Corporation issue Exchange Debentures in denominations other
         than $1,000 or in an integral multiple thereof.  Cash will be paid in
         lieu of any such fraction of an Exchange Debenture which would
         otherwise have been issued (which shall be determined with respect to
         the aggregate principal amount of Exchange Debentures to be issued to
         a holder upon any such exchange). Interest will accrue on the Exchange
         Debentures from the date of exchange.

                 Prior to effecting any exchange hereunder, the Corporation
         shall appoint a trustee to serve in the capacity contemplated by an
         indenture between the Corporation and such trustee,  containing
         customary terms and conditions.

                 The EXCHANGE RATIO shall be, as of any Dividend Payment Date,
         $1.00 (or fraction thereof) of principal amount of Exchange Debenture
         for each $1.00 of (i) Liquidation Value plus (ii) accrued and unpaid
         cash dividends, if any, per share of Senior Preferred Stock held by a
         holder on the applicable exchange date.

                 "AFFILIATES" shall have the meaning ascribed to such term in
         the Investors' Agreement.

                 "EXCHANGE DEBENTURES" means 13%  Subordinated Exchange
         Debentures due 2010 of the Corporation, to be issued pursuant to an
         indenture between the Corporation and a trustee, containing customary
         terms and conditions, in accordance with the Term Sheet attached as
         Exhibit A hereto.

                 "PERMITTED TRANSFEREES" shall have the meaning ascribed to
         such term in the Investors' Agreement.

                          (b) Procedure for Exchange. (i) In the event the
         Corporation shall exchange shares of Senior Preferred Stock, notice of
         such exchange shall be given by first class mail, postage prepaid,
         mailed not less than 30 days nor more than 60 days prior to the
         exchange date, to each holder of record of the shares to be exchanged
         at such holder's address as the same appears on the stock register of
         the Corporation; provided that neither the failure to give such notice
         nor any defect therein shall affect the validity of the giving of
         notice for the exchange of any share of Senior Preferred Stock to be
         exchanged except as to the holder to whom the Corporation has failed
         to give said notice or except as to the holder whose notice was
         defective. Each such notice shall state: (A) the exchange date; (B)
         the number of shares of Senior Preferred Stock to be exchanged; (C)
         the Exchange Ratio; (D) the place or places where certificates for
         such shares are to be exchanged for notes evidencing the Exchange
         Debentures to be received by the exchanging holder; and (E) that
         dividends on the shares to be exchanged will cease to accrue on such
         exchange date.

                          (ii) Prior to giving notice of intention to exchange,
                          the Corporation shall execute and deliver to a bank or
                          trust company selected by the Corporation an indenture
                          containing customary terms and conditions. The
                          Corporation will cause the Exchange Debentures to be
                          authenticated on the





                                       15
<PAGE>   16
                 Dividend Payment Date on which the exchange is effective, and
                 will pay interest on the Exchange Debentures at the rate and
                 on the dates specified in such indenture from the exchange
                 date.

                          The Corporation will not give notice of its intention
                 to exchange under paragraph 6(b)(i) hereof unless it shall
                 file at the place or places (including a place in the Borough
                 of Manhattan, The City of New York) maintained for such
                 purpose an opinion of counsel (who may be an employee of the
                 Corporation) to the effect that (i) the indenture has been
                 duly authorized, executed and delivered by the Corporation,
                 has been duly qualified under the Trust Indenture Act of 1939
                 (or that such qualification is not necessary) and constitutes
                 a valid and binding instrument enforceable against the
                 Corporation in accordance with its terms (subject, as to
                 enforcement, to bankruptcy, insolvency, reorganization and
                 other laws of general applicability relating to or affecting
                 creditors' rights and to general equity principles, and
                 subject to such other qualifications as are then customarily
                 contained in opinions of counsel experienced in such matters),
                 (ii) the Exchange Debentures have been duly authorized and,
                 when executed and authenticated in accordance with the
                 provisions of the indenture and delivered in exchange for the
                 shares of Preferred Stock, will constitute valid and binding
                 obligations of the Corporation entitled to the benefits of the
                 indenture (subject as aforesaid), (iii) neither the execution
                 nor delivery of the indenture or the Exchange Debentures nor
                 compliance with the terms, conditions or provisions of such
                 instruments will result in a breach or violation of any of the
                 terms or provisions of, or constitute a default under, any
                 indenture, mortgage, deed of trust or agreement or instrument,
                 known to such counsel, to which the Corporation or any of its
                 subsidiaries is a party or by which it or any of them is
                 bound, or any decree, judgment, order, rule or regulation,
                 known to such counsel, of any court or governmental agency or
                 body having jurisdiction over the Corporation and





                                       16
<PAGE>   17
                          such subsidiaries or any of their properties, (iv) the
                          Exchange Debentures have been duly registered for such
                          exchange with the Securities and Exchange Commission
                          under a registration statement that has become
                          effective under the Securities Act of 1933 (the "Act")
                          or that the exchange of the Exchange Debentures for
                          the shares of Senior Preferred Stock is exempt from
                          registration under the Act, and (v) the Corporation
                          has sufficient legally available funds for such
                          exchange such that such exchange is permitted under
                          applicable law.

                          (iii)  Notice having been mailed as aforesaid, from
                          and after the exchange date (unless default shall be
                          made by the Corporation in issuing Exchange Debentures
                          in exchange for the shares called for exchange),
                          dividends on the shares of Senior Preferred Stock so
                          called for exchange shall cease to accrue, and all
                          rights of the holders thereof as stockholders of the
                          Corporation (except the right to receive from the
                          Corporation the Exchange Debentures and any rights
                          such holder, upon the exchange, may have as a holder
                          of the Exchange Debenture) shall cease. Upon surrender
                          in accordance with said notice of the certificates for
                          any shares so exchanged (properly endorsed or assigned
                          for transfer, if the Board of Directors of the
                          Corporation shall so require and the notice shall so
                          state), such share shall be exchanged by the
                          Corporation for the Exchange Debentures at the
                          Exchange Ratio. In case fewer than all the shares
                          represented by any such certificate are exchanged, a
                          new certificate shall be issued representing the
                          unexchanged shares without cost to the holder thereof.

                          (iv)   Each exchange shall be deemed to have been
                          effected immediately after the close of business on
                          the relevant Dividend Payment Date, and the person in
                          whose name or names any Exchange Debentures shall be
                          issuable upon such exchange shall be deemed to have
                          become the holder of record of the





                                       17
<PAGE>   18
                          Exchange Debentures represented thereby at such time
                          on such Dividend Payment Date.

                          (v)  Prior to the delivery of any securities which the
                          Corporation shall be obligated to deliver upon
                          exchange of the Senior Preferred Stock, the
                          Corporation shall comply with all applicable federal
                          and state laws and regulations which require action to
                          be taken by the Corporation.

                 (c) The Corporation will pay any and all documentary stamp or
         similar issue or transfer taxes payable in respect of the issue or
         delivery of notes evidencing Exchange Debentures on exchange of the
         Senior Preferred Stock pursuant hereto; provided that the Corporation
         shall not be required to pay any tax which may be payable in respect
         of any transfer involved in the issue or delivery of Exchange
         Debentures in a name other than that of the holder of the Senior
         Preferred Stock to be exchanged and no such issue or delivery shall be
         made unless and until the person requesting such issue or delivery has
         paid to the Corporation the amount of any such tax or has established,
         to the satisfaction of the Corporation, that such tax has been paid.

                          (8) VOTING RIGHTS. (a)  The holders of record of
         shares of Senior Preferred Stock shall not be entitled to any voting
         rights except as hereinafter provided in this paragraph (8), as
         otherwise provided by law or as provided in the Investors' Agreement.

                          (b) If and whenever (i) four consecutive or six
         quarterly cash dividends payable on the Senior Preferred Stock have not
         been paid in full, (ii) for any reason (including the reason that funds
         are not legally available for a redemption), the Corporation shall have
         failed to discharge any Mandatory Redemption Obligation (including a
         redemption in the Event of a Change of Control pursuant to Section 5(c)
         hereof), (iii) the Corporation shall have failed to provide the notice
         required by Section 6(c) hereof within the time period specified in
         such section or (iv) the Corporation shall have failed to comply with
         Sections 3(d), 3(e) or 8(c) hereof, (1) the number of directors then
         constituting the Board of Directors shall be increased by two and the
         holders of a majority of the outstanding shares of Senior Preferred
         Stock, together with the holders of shares of every other





                                       18
<PAGE>   19
         series of preferred stock upon which like rights have been conferred
         and are exercisable (resulting from either the failure to pay
         dividends or the failure to redeem) (any such series is referred to as
         the "PREFERRED SHARES"), voting as a single class regardless of
         series, shall be entitled to elect the two additional directors to
         serve on the Board of Directors at any annual meeting of stockholders
         or special meeting held in place thereof, or at a special meeting of
         the holders of the Senior Preferred Stock and the Preferred Shares
         called as hereinafter provided. Whenever (i) all arrears in cash
         dividends on the Senior Preferred Stock and the Preferred Shares then
         outstanding shall have been paid and cash dividends thereon for the
         current quarterly dividend period shall have been paid or declared and
         set apart for payment, (ii) the Corporation shall have fulfilled its
         Mandatory Redemption Obligation, (iii) fulfilled its obligation to
         provide notice as specified in subsection (b)(iii) hereof, or (iv) the
         Corporation shall have complied with Sections 3(d), 3(e), or 8(c)
         hereof, as the case may be, then the right of the holders of the
         Senior Preferred Stock to elect such additional two directors shall
         cease (but subject always to the same provisions for the vesting of
         such voting rights in the case of any similar future (i) arrearage in
         six consecutive quarterly cash dividends, (ii) failure to fulfill any
         Mandatory Redemption Obligation, (iii) failure to fulfill the
         obligation to provide the notice required by Section 6(d) hereof
         within the time period specified in such section or (iv) failure to
         comply with Sections 3(d), 3(e), or 8(c)) and the terms of office of
         all persons elected as directors by the holders of the Senior
         Preferred Stock shall forthwith terminate and the number of the Board
         of Directors shall be reduced accordingly. At any time after such
         voting power shall have been so vested in the holders of shares of
         Senior Preferred Stock and the Preferred Shares, the secretary of the
         Corporation may, and upon the written request of any holder of Senior
         Preferred Stock (addressed to the secretary at the principal office of
         the Corporation) shall, call a special meeting of the holders of the
         Senior Preferred Stock and of the Preferred Shares for the election of
         the two directors to be elected by them as herein provided, such call
         to be made by notice similar to that provided in the Bylaws of the
         Corporation for a special meeting of the stockholders or as required
         by law. If any such special meeting required to be called as above
         provided shall not be called by the secretary within 20 days after
         receipt of any such request, then any holder of shares of Senior
         Preferred Stock may call such meeting, upon the notice above provided,
         and for that purpose shall have access to the stock books of the
         Corporation. The directors elected





                                       19
<PAGE>   20
         at any such special meeting shall hold office until the next annual
         meeting of the stockholders or special meeting held in lieu thereof if
         such office shall not have previously terminated as above provided. If
         any vacancy shall occur among the directors elected by the holders of
         the Senior Preferred Stock and the Preferred Shares, a successor shall
         be elected by the Board of Directors, upon the nomination of the
         then-remaining director elected by the holders of the Senior Preferred
         Stock and the Preferred Shares or the successor of such remaining
         director, to serve until the next annual meeting of the stockholders
         or special meeting held in place thereof if such office shall not have
         previously terminated as provided above.

                 (c) Without the written consent of a majority of the
         outstanding shares of Senior Preferred Stock or the vote of holders of
         a majority of the outstanding shares of Senior Preferred Stock at a
         meeting of the holders of Senior Preferred Stock called for such
         purpose, the Corporation will not (i) amend, alter or repeal any
         provision of the Certificate of Incorporation (by merger or otherwise)
         so as to adversely affect the preferences, rights or powers of the
         Senior Preferred Stock; provided that any such amendment that
         decreases the dividend payable on or the Liquidation Value of the
         Senior Preferred Stock shall require the affirmative vote of holders
         of each share of Senior Preferred Stock at a meeting of holders of
         Senior Preferred Stock called for such purpose or written consent of
         the holder of each share of Senior Preferred Stock; or (ii) create,
         authorize or issue any class of stock ranking prior to, or on a parity
         with, the Senior Preferred Stock with respect to dividends or upon
         liquidation, dissolution, winding up or otherwise, or increase the
         authorized number of shares of any such class or series, or reclassify
         any authorized stock of the Corporation into any such prior or parity
         shares or create, authorize or issue any obligation or security
         convertible into or evidencing the right to purchase any such prior or
         parity shares, except that the Corporation may, without such approval,
         create authorize and issue Parity Securities for the purpose of
         utilizing the proceeds from the issuance of such Parity Securities for
         the redemption or repurchase of all outstanding shares of Senior
         Preferred Stock in accordance with the terms hereof or of the
         Investors' Agreement.

                 (d) In exercising the voting rights set forth in this
         paragraph (8), each share of Senior Preferred Stock shall have one
         vote per share, except that when any other series of preferred stock
         shall





                                       20
<PAGE>   21
         have the right to vote with the Senior Preferred Stock as a single
         class on any matter, then the Senior Preferred Stock and such other
         series shall have with respect to such matters one vote per $25 of
         Liquidation Value or other liquidation preference. Except as otherwise
         required by applicable law or as set forth herein, the shares of
         Senior Preferred Stock shall not have any relative, participating,
         optional or other special voting rights and powers and the consent of
         the holders thereof shall not be required for the taking of any
         corporate action.

                 (9) REPORTS. So long as any of the Senior Preferred Stock is
         outstanding, the Corporation will furnish the holders thereof with the
         quarterly and annual financial reports that the Corporation is
         required to file with the Securities and Exchange Commission pursuant
         to Section 13 or Section 15(d) of the Securities Exchange Act of 1934
         or, in the event the Corporation is not required to file such reports,
         reports containing the same information as would be required in such
         reports.

                 (10) GENERAL PROVISIONS. (a)  The term "PERSON" as used herein
         means any corporation, limited liability company, partnership, trust,
         organization, association, other entity or individual.

                 (b)      The term "OUTSTANDING," when used with reference to
         shares of stock, shall mean issued shares, excluding shares held by
         the Corporation or a subsidiary.

                 (c)      The headings of the paragraphs, subparagraphs,
         clauses and subclauses used herein are for convenience of reference
         only and shall not define, limit or affect any of the provisions
         hereof.

                 (d)      Each holder of Senior Preferred Stock, by acceptance
         thereof, acknowledges and agrees that payments of dividends, interest,
         premium and principal on, and exchange, redemption and repurchase of,

         herein "person" means any other corporation, partnership, association,
         firm, trust, joint venture, political subdivision, or instrumentality)
         or other organization in which one or more of its directors, officers,
         or stockholders are directors, officers or stockholders, or have a
         financial interest, shall be void or voidable solely for this reason,
         or solely because the director or officer is present at or
         participates in the meeting of the board or committee which authorizes
         the contract or transaction, or solely because his, her, or their
         votes are counted for such purpose, if: (i) the material facts as to
         his or her relationship or interest and as to the contract or
         transaction are disclosed or are known to the board of directors or
         the committee, and the board of directors or committee in good faith
         authorizes the contract or transaction by the affirmative votes of a
         majority of the disinterested directors, even though the disinterested
         directors be less than a quorum; or (ii) the material facts as to his
         or her relationship or interest and as to the contract or transaction
         are disclosed or are known to the stockholders entitled to vote
         thereon, and the contract or transaction is specifically approved in
         good faith by vote of the stockholders; or (iii) the contract or
         transaction is fair as to the Corporation as of the time it is
         authorized, approved, or ratified by the board of directors, a
         committee thereof (to the extent permitted by applicable law), or the
         stockholders.  Common or interested directors may be counted in
         determining the presence of a quorum at a meeting of the board of
         directors or of a committee which authorizes the contract or
         transaction.

                 SIXTH: The Board of Directors shall have the power to adopt,
         amend or repeal the bylaws of the Corporation.

                 SEVENTH: Election of directors need not be by written ballot
         unless the bylaws of the Corporation so provide.

                 EIGHTH:  A director of the Corporation shall not be personally
         liable to the Corporation or its stockholders for monetary damages for
         breach of fiduciary duty as a director, except for liability (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 knowing violation of law, (iii)
         under Section 174 of the Delaware Law, or (iv) for any transaction
         from which the director derived an improper personal benefit.  Any
         repeal or amendment of this Article EIGHTH by the stockholders of the
         Corporation shall be prospective only,





                                       22
<PAGE>   23
         and shall not adversely affect any limitation on the personal
         liability of a director of the Corporation arising from an act or
         omission occurring prior to the time of such repeal or amendment.  In
         addition to the circumstances in which a director of the Corporation
         is not personally liable as set forth in the foregoing provisions of
         this Article EIGHTH, a director shall not be liable to the Corporation
         or its stockholders to such further extent as permitted by any law
         hereafter enacted, including without limitation any subsequent
         amendment to the Delaware Law.

         Delaware Law.

                 (2)(a) Each person (and the heirs, executors or administrators
         of such person) who was or is a party or is threatened to be made a
         party to, or is involved in any threatened, pending or completed
         action, suit or proceeding, whether civil, criminal, administrative or
         investigative, by reason of the fact that such person is or was a
         director or officer of the Corporation or is or was serving at the
         request of the Corporation as a director or officer of another
         corporation, partnership, joint venture, trust or other enterprise,
         shall be indemnified and held harmless by the Corporation to the
         fullest extent permitted by Delaware Law.  The right to
         indemnification conferred in this Article NINTH shall also include the
         right to be paid by the Corporation the expenses incurred in
         connection with any such proceeding in advance of its final
         disposition to the fullest extent authorized by Delaware Law.  The
         right to indemnification conferred in this Article NINTH shall be a
         contract right.

                 (b) The Corporation may, by action of its Board of Directors,
         provide indemnification to such of the officers, employees and agents
         of the Corporation to such extent and to such effect as the Board of

         Law.

         insurance on behalf of any person who is or was a director, officer,
         employee or agent of the Corporation, or is or was serving at the
         request of the Corporation as a director, officer, employee or agent
         of another corporation, partnership, joint

         venture, trust or other enterprise against any expense, liability or
         loss incurred by such person in any such capacity or arising out of
         his status as such, whether or not the Corporation would have the
         power to indemnify him against such liability under Delaware Law.

                 (4) The rights and authority conferred in this Article NINTH
         shall not be exclusive of any other right which any person may
         otherwise have or hereafter acquire.

                 (5) Neither the amendment nor repeal of this Article NINTH,
         nor the adoption of any provision of this Certificate of Incorporation
         or the bylaws of the Corporation, nor, to the fullest extent permitted
         by Delaware Law, any modification of law, shall eliminate or reduce
         the effect of this Article NINTH in respect of any acts or omissions
         occurring prior to such amendment, repeal, adoption or modification.

                 TENTH:  The Corporation expressly elects not to be governed by
         Section 203 of the Delaware Law.

                 ELEVENTH: The Corporation reserves the right to amend this
         Certificate of Incorporation in any manner permitted by Delaware Law
         and, with the sole exception of those rights and powers conferred
         under the above Article NINTH, all rights and powers conferred herein
         on stockholders, directors and officers, if any, are subject to this
         reserved power.

 ISSUE:                            13% Exchange Debentures (the "EXCHANGE DEBENTURES") to
                                   be issued by the Corporation, at its option, in exchange
                                   for any or all the outstanding shares of 13% Senior
                                   Exchangeable Preferred Stock due 2010 (the "SENIOR

                                   semi-annual interest will accrete on a compound basis
                                   (i.e. non-cash pay) and increase the face amount of the
                                   Exchange Debentures, thereafter interest will be payable
                                   in cash.

                                   the Corporation.


 OPTIONAL REDEMPTION:              The Exchange Debentures will be redeemable at any time
                                   after May 15, 2003 at the option of the Corporation, in
                                   whole or in part, at the same redemption prices set
                                   forth in the designation of the Senior Preferred Stock
                                   set forth in Article FOURTH, paragraph (c) of the
                                   Restated Certificate of Incorporation of the Surviving
                                   Corporation.

                                   any part of such holder's Exchange Debentures at a
                                   purchase price of 101% of the sum of the accreted value

                                   any indebtedness subordinated to the Exchange

         SECTION 2.01. Time and Place of Meetings. All meetings of stockholders
shall be held at such place, either within or without the State of Delaware, on
such date and at such time as may be determined from time to time by the Board
of Directors (or the Chairman in the absence of a designation by the Board of
Directors).

         SECTION 2.02. Annual Meetings. Annual meetings of stockholders,
commencing with the year 1998, shall be held to elect the Board of Directors and

<PAGE>   2


         SECTION 2.03.  Special Meetings.  Special meetings of stockholders may
be called by the Board of Directors or the chairman of the Board and shall be
called by the Secretary at the request in writing of holders of record of a
majority of the outstanding capital stock of the Corporation entitled to vote.
Such request shall state the purpose or purposes of the proposed meeting.

         SECTION 2.04. Notice of Meetings and Adjourned Meetings; Waivers of
Notice. (a) Whenever stockholders are required or permitted to take any action
at a meeting, a written notice of the meeting shall be given which shall state
the place, date and hour of the meeting, and, in the case of a special meeting,
the purpose or purposes for which the meeting is called. Unless otherwise
provided by the General Corporation Law of the State of Delaware as the same
exists or may hereafter be amended ("DELAWARE LAW"), such notice shall be given
not less than 10 nor more than 60 days before the date of the meeting to each
stockholder of record entitled to vote at such meeting. Unless these bylaws
otherwise require, when a meeting is adjourned to another time or place (whether
or not a quorum is present), notice need not be given of the adjourned meeting
if the time and place thereof are announced at the meeting at which the
adjournment is taken. At the adjourned meeting, the Corporation may transact any
business which might have been transacted at the original meeting. If the
adjournment is for more than 30 days, or after the adjournment a new record date
is fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

          (b) A written waiver of any such notice signed by the person entitled
thereto, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends the meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Business transacted at any special meeting of stockholders shall be
limited to the purposes stated in the notice.

         SECTION 2.05. Quorum. Unless otherwise provided under the certificate
of incorporation or these bylaws and subject to Delaware Law, the presence, in
person or by proxy, of the holders of a majority of the outstanding capital
stock of the Corporation entitled to vote at a meeting of stockholders shall
constitute a quorum for the transaction of business.

         SECTION 2.06. Voting. (a) Unless otherwise provided in the certificate
of incorporation and subject to Delaware Law, each stockholder shall be entitled
to one vote for each outstanding share of capital stock of the Corporation held
by such stockholder. Unless otherwise provided in Delaware Law, the certificate
of incorporation or these bylaws, the affirmative vote of a majority of the
shares of


                                       2

<PAGE>   3

capital stock of the Corporation present, in person or by proxy, at a meeting of
stockholders and entitled to vote on the subject matter shall be the act of the
stockholders.

          (b) Each stockholder entitled to vote at a meeting of stockholders or
to express consent or dissent to a corporate action in writing without a meeting
may authorize another person or persons to act for him by proxy, but no such
proxy shall be voted or acted upon after three years from its date, unless the
proxy provides for a longer period.

         SECTION 2.07. Action by Consent. (a) Unless otherwise provided in the
certificate of incorporation, any action required to be taken at any annual or
special meeting of stockholders, or any action which may be taken at any annual
or special meeting of stockholders, may be taken without a meeting, without
prior notice and without a vote, if a consent or consents in writing, setting
forth the action so taken, shall be signed by the holders of outstanding capital
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted and shall be delivered to the Corporation by
delivery to its registered office in Delaware, its principal place of business,
or an officer or agent of the Corporation having custody of the book in which
proceedings of meetings of stockholders are recorded. Delivery made to the
Corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested. Prompt notice of the taking of the corporate
action without a meeting by less than unanimous written consent shall be given
to those stockholders who have not consented in writing.

          (b) Every written consent shall bear the date of signature of each
stockholder who signs the consent, and no written consent shall be effective to
take the corporate action referred to therein unless, within 60 days of the
earliest dated consent delivered in the manner required by this Section and
Delaware Law to the Corporation, written consents signed by a sufficient number
of holders to take action are delivered to the Corporation by delivery to its
registered office in Delaware, its principal place of business, or an officer or
agent of the Corporation having custody of the book in which proceedings of
meetings of stockholders are recorded. Delivery made to the Corporation's
registered office shall be by hand or by certified or registered mail, return
receipt requested.

         SECTION 2.08. Organization. At each meeting of stockholders, the
Chairman of the Board, if one shall have been elected, (or in his absence or if
one shall not have been elected, the President) shall act as chairman of the
meeting. The Secretary (or in his absence or inability to act, the person whom
the chairman of the meeting shall appoint secretary of the meeting) shall act as
secretary of the meeting and keep the minutes thereof.

elected shall hold office until his successor is elected and qualified or until

         SECTION 3.03. Quorum and Manner of Acting. Unless the certificate of
incorporation or these bylaws require a greater number, a majority of the total
number of directors shall constitute a quorum for the transaction of business,
and the affirmative vote of a majority of the directors present at meeting at

meeting is adjourned to another time or place (whether or not a quorum is
present), notice need not be given of the adjourned meeting if the time and
place thereof are announced at the meeting at which the adjournment is taken. At
the adjourned meeting, the Board of Directors may transact any business which

may adjourn the meeting, from time to time, without notice other than
announcement at the meeting, until a quorum shall be present.

         SECTION 3.04. Time and Place of Meetings. The Board of Directors shall
hold its meetings at such place, either within or without the State of Delaware,

Directors).

         SECTION 3.05. Annual Meeting. The Board of Directors shall meet for the

of such meeting need not be given. In the event such annual meeting is not so
held, the annual meeting of the Board of Directors may be held at such place
either within or without the State of Delaware, on such date and at such time as

3.07 hereof or in a waiver of notice thereof signed by any director who chooses
to waive the requirement of notice.

Directors may be called by the Chairman of the Board or the President and shall
be called by the Chairman of the Board, President or Secretary on the written
request of three directors. Notice of special meetings of the Board of Directors
shall be given to each director at least three days before the date of the
meeting in such manner as is determined by the Board of Directors.

         SECTION 3.08. Committees. The Board of Directors may, by resolution
passed by a majority of the whole Board, designate one or more committees, each
committee to consist of one or more of the directors of the Corporation. The
Board may designate one or more directors as alternate members of any committee,
who may replace any absent or disqualified member at any meeting of the
committee. Any such committee, to the extent provided in the resolution of the
Board of Directors, shall have and may exercise all the powers and authority of
the Board of Directors in the management of the business and affairs of the
Corporation, and may authorize the seal of the Corporation to be affixed to all
papers which may require it; but no such committee shall have the power or
authority in reference to amending the certificate of incorporation, adopting an
agreement of merger or consolidation, recommending to the stockholders the sale,
lease or exchange of all or substantially all of the Corporation's property and
assets, recommending to the stockholders a dissolution of the Corporation or a
revocation of a dissolution, or amending the bylaws of the Corporation; and
unless the resolution of the Board of Directors or the certificate of
incorporation expressly so provide, no such committee shall have the power or
authority to declare a dividend or to authorize the issuance of stock. Each
committee shall keep regular minutes of its meetings and report the same to the
Board of Directors when required.

         SECTION 3.09. Action by Consent. Unless otherwise restricted by the
certificate of incorporation or these bylaws, any action required or permitted
to be taken at any meeting of the Board of Directors or of any committee thereof
may be taken without a meeting, if all members of the Board or committee, as the
case


                                       5
<PAGE>   6


may be, consent thereto in writing, and the writing or writings are filed with
the minutes of proceedings of the Board or committee.

         SECTION 3.10. Telephonic Meetings. Unless otherwise restricted by the
certificate of incorporation or these bylaws, members of the Board of Directors,
or any committee designated by the Board of Directors, may participate in a
meeting of the Board of Directors, or such committee, as the case may be, by
means of conference telephone or similar communications equipment by means of
which all persons participating in the meeting can hear each other, and such
participation in a meeting shall constitute presence in person at the meeting.

         SECTION 3.11. Resignation. Any director may resign at any time by
giving written notice to the Board of Directors or to the Secretary of the
Corporation. The resignation of any director shall take effect upon receipt of
notice thereof or at such later time as shall be specified in such notice; and
unless otherwise specified therein, the acceptance of such resignation shall not
be necessary to make it effective.

         SECTION 3.12. Vacancies. Unless otherwise provided in the certificate
of incorporation, vacancies and newly created directorships resulting from any
increase in the authorized number of directors elected by all the stockholders
having the right to vote as a single class may be filled by a majority of the
directors then in office, although less than a quorum, or by a sole remaining
director. Whenever the holders of any class or classes of stock or series
thereof are entitled to elect one or more directors by the certificate of
incorporation, vacancies and newly created directorships of such class or
classes or series may be filled by a majority of directors elected by such class
or classes or series thereof then in office, or by a sole remaining director so
elected. Each director so chosen shall hold office until his successor is
elected and qualified, or until his earlier death, resignation or removal. If
there are no directors in office, then an election of directors may be held in
accordance with Delaware Law. Unless otherwise provided in the certificate of
incorporation, when one or more directors shall resign from the Board, effective
at a future date, a majority of the directors then in office, including those
who have so resigned, shall have the power to fill such vacancy or vacancies,
the vote thereon to take effect when such resignation or resignations shall
become effective, and each director so chosen shall hold office as provided in
the filling of other vacancies.

         SECTION 3.13. Removal. Any director or the entire Board of Directors
may be removed, with or without cause, at any time by the affirmative vote of
the holders of a majority of the outstanding capital stock of the Corporation
entitled to vote and the vacancies thus created may be filled in accordance with
Section 3.12 herein.

as the Board of Directors shall determine.

         SECTION 4.03. Subordinate Officers. In addition to the principal
officers enumerated in Section 4.01 hereof, the Corporation may have one or more
Assistant Treasurers, Assistant Secretaries and Assistant Controllers and such
other subordinate officers, agents and employees as the Board of Directors may

Directors may from time to time determine. The Board of Directors may delegate
to any principal officer the power to appoint and to remove any such subordinate
officers, agents or employees.

         SECTION 4.06. Powers and Duties. The officers of the Corporation shall

                               GENERAL PROVISIONS

         SECTION 5.01. Fixing the Record Date. (a) In order that the Corporation
may determine the stockholders entitled to notice of or to vote at any meeting
of stockholders or any adjournment thereof, the Board of Directors may fix a
record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the Board of Directors, and
which record date shall not be more than 60 nor less than 10 days before the
date of such meeting. If no record date is fixed by the Board of Directors, the
record date for determining stockholders entitled to notice of or to vote at a
meeting of stockholders shall be at the close of business on the day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the day next preceding the day on which the meeting is
held. A determination of stockholders of record entitled to notice of or to vote
at a meeting of stockholders shall apply to any adjournment of the meeting;
provided that the Board of Directors may fix a new record date for the adjourned
meeting.

          (b) In order that the Corporation may determine the stockholders
entitled to consent to corporate action in writing without a meeting, the Board
of Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors, and which date shall not be more than 10 days after the date upon
which the resolution fixing the record date is adopted by the Board of
Directors. If no record date has been fixed by the Board of Directors, the
record date for determining stockholders entitled to consent to corporate action
in writing without a meeting, when no prior action by the Board of Directors is
required by Delaware Law, shall be the first date on which a signed written
consent setting forth the action taken or proposed to be taken is delivered to
the Corporation by delivery to its registered office in Delaware, its principal
place of business, or an officer or agent of the Corporation having custody of
the book in which proceedings of meetings of stockholders are recorded. Delivery
made to the Corporation's registered office shall be by hand


                                       8

<PAGE>   9

or by certified or registered mail, return receipt requested. If no record date
has been fixed by the Board of Directors and prior action by the Board of
Directors is required by Delaware Law, the record date for determining
stockholders entitled to consent to corporate action in writing without a
meeting shall be at the close of business on the day on which the Board of
Directors adopts the resolution taking such prior action.

          (c) In order that the Corporation may determine the stockholders
entitled to receive payment of any dividend or other distribution or allotment
of any rights or the stockholders entitled to exercise any rights in respect of
any change, conversion or exchange of stock, or for the purpose of any other
lawful action, the Board of Directors may fix a record date, which record date
shall not precede the date upon which the resolution fixing the record date is
adopted, and which record date shall be not more than 60 days prior to such
action. If no record date is fixed, the record date for determining stockholders
for any such purpose shall be at the close of business on the day on which the
Board of Directors adopts the resolution relating thereto.

         SECTION 5.02. Dividends. Subject to limitations contained in Delaware
Law and the certificate of incorporation, the Board of Directors may declare and
pay dividends upon the shares of capital stock of the Corporation, which
dividends may be paid either in cash, in property or in shares of the capital
stock of the Corporation.

         SECTION 5.04. Corporate Seal. The corporate seal shall have inscribed
thereon the name of the Corporation, the year of its organization and the words
"Corporate Seal, Delaware". The seal may be used by causing it or a facsimile
thereof to be impressed, affixed or otherwise reproduced.

         SECTION 5.05. Voting of Stock Owned by the Corporation. The Board of
Directors may authorize any person, on behalf of the Corporation, to attend,
vote at and grant proxies to be used at any meeting of stockholders of any
corporation (except this Corporation) in which the Corporation may hold stock.

         SECTION 5.06. Amendments. These bylaws or any of them, may be altered,
amended or repealed, or new bylaws may be made, by the stockholders entitled to
vote thereon at any annual or special meeting thereof or by the Board of
Directors.

                                 THE DEBENTURES

SECTION 2.01.FORM AND DATING.

          (a)    General.  The Debentures and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A hereto.  The
Debentures may have notations, legends or endorsements required by law, stock
exchange rule or usage.  Each Debenture shall be dated the date of its
authentication.  The Debentures shall be in denominations of $1,000 and
integral multiples thereof except that Debentures used to pay Liquidated
Damages may be in other denominations.

         The terms and provisions contained in the Debentures shall constitute,
and are hereby expressly made, a part of this Indenture and the Issuer and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.  However, to the extent any
provision of any Debenture conflicts with the express provisions of this
Indenture, the provisions of this Indenture shall govern and be controlling.

          (b)    Global Debentures.  Debentures issued in global form shall be
substantially in the form of Exhibit A-1 attached hereto (including the Global
Debenture Legend thereon and the "Schedule of Exchanges of Interests in the
Global Debenture" attached thereto).  Debentures issued in definitive form
shall be substantially in the form of Exhibit A-1 attached hereto (but without
the Global Debenture Legend thereon and without the "Schedule of Exchanges of
Interests in the Global Debenture" attached thereto).  Each Global Debenture
shall represent such of the outstanding Debentures as shall be specified
therein and each shall provide that it shall represent the aggregate principal
amount at maturity of outstanding Debentures from time to time endorsed thereon
and that the aggregate principal amount at maturity of outstanding Debentures
represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges and redemptions.  Any endorsement of a Global
Debenture to reflect the amount of any increase or decrease in the aggregate
principal amount at maturity of outstanding Debentures represented thereby
shall be made by the Trustee or the Debenture Custodian, at the direction of
the Trustee, in accordance with instructions given by the Holder thereof as
required by Section 2.06 hereof.

          (c)    Temporary Global Debentures.  Debentures offered and sold in
reliance on Regulation S shall be issued initially in the form of Exhibit A-2
attached hereto, which shall be deposited on behalf of the purchasers of the
Debentures represented thereby with the Trustee, at its New York office, as
custodian for the Depositary, and registered in the name of the Depositary or
the nominee of the Depositary for the accounts of designated agents holding on
behalf of Euroclear or Cedel Bank, duly executed by the Issuer and
authenticated by the Trustee as hereinafter provided.  The Restricted Period
shall be terminated upon the receipt by the Trustee of (i) a written
certificate from the Depositary, together with copies of certificates from
Euroclear and Cedel Bank certifying that they have received certification of
non-United States beneficial ownership of 100% of the aggregate principal
amount at maturity of the Regulation S Temporary Global Debenture (except to
the extent of any beneficial owners thereof who acquired an interest therein
during the Restricted Period pursuant to another exemption from registration
under the Securities Act and who will take delivery of a beneficial ownership
interest in a 144A Global Debenture, all as contemplated by Section 2.06(a)(ii)
hereof), and (ii) an Officers' Certificate from the Issuer.  Following the
termination of the Restricted Period, beneficial interests in the Regulation S
Temporary Global Debenture shall be exchanged for beneficial interests in
Regulation S Permanent Global Debentures pursuant to the Applicable Procedures.
Simultaneously with the authentication of Regulation S Permanent Global
Debentures, the Trustee shall cancel the Regulation S Temporary Global
Debenture.  The aggregate principal amount at maturity of the Regulation S
Temporary Global Debenture and the Regulation S Permanent Global Debentures may
from time to time be increased or decreased by adjustments made on the records
of the Trustee and the Depositary or its nominee, as the case may be, in
connection with transfers of interest as hereinafter provided.

          (d)    Euroclear and Cedel Procedures Applicable.  The provisions of
the "Operating Procedures of the Euroclear System" and "Terms and Conditions
Governing Use of Euroclear" and the "General Terms and Conditions of Cedel
Bank" and "Customer Handbook" of Cedel Bank shall be applicable to transfers of
beneficial





                                       15
<PAGE>   23
interests in the Regulation S Temporary Global Debenture and the Regulation S
Permanent Global Debentures that are held by Participants through Euroclear or
Cedel Bank.

SECTION 2.02.    EXECUTION AND AUTHENTICATION.

         One Officer shall sign the Debentures for the Issuer by manual or
facsimile signature.  The Issuer's seal may be reproduced on the Debentures and
may be in facsimile form.

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

         A Debenture shall not be valid until authenticated by the manual
signature of the Trustee.  The signature shall be conclusive evidence that the
Debenture has been authenticated under this Indenture.

         The Trustee shall, upon a written order of the Issuer signed by one
Officer (an "Authentication Order"), authenticate Debentures for original issue
up to the aggregate principal amount at maturity stated in paragraph 4 of the
Debentures plus Debentures issued to pay Liquidated Damages pursuant to
paragraph 2 of the Debentures.  The aggregate principal amount at maturity of
Debentures outstanding at any time may not exceed such amount except as
provided in Section 2.07 hereof.

         The Trustee may appoint an authenticating agent acceptable to the
Issuer to authenticate Debentures.  An authenticating agent may authenticate
Debentures 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 Holders or an
Affiliate of the Issuer.

SECTION 2.03.    REGISTRAR AND PAYING AGENT.

         The Issuer shall maintain an office or agency where Debentures may be
presented for registration of transfer or for exchange ("Registrar") and an
office or agency where Debentures may be presented for payment ("Paying
Agent").  The Registrar shall keep a register of the Debentures and of their
transfer and exchange.  The Issuer 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 agent.
The Issuer may change any Paying Agent or Registrar without notice to any
Holder.  The Issuer shall notify the Trustee in writing of the name and address
of any Agent not a party to this Indenture.  If the Issuer fails to appoint or
maintain another entity as Registrar or Paying Agent, the Trustee shall act as
such.  The Issuer or any of its Subsidiaries may act as Paying Agent or
Registrar.

         The Issuer initially appoints The Depository Trust Company ("DTC") to
act as Depositary with respect to the Global Debentures.

         The Issuer initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Debenture Custodian with respect to the Global
Debentures.

SECTION 2.04.    PAYING AGENT TO HOLD MONEY IN TRUST.

         The Issuer shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium or Liquidated Damages, if any, or interest on the
Debentures, and will notify the Trustee of any default by the Issuer in making
any such payment.  While any such default continues, the Trustee may require a
Paying Agent to pay all money held by it to the Trustee.  The Issuer at any
time may require a Paying Agent to pay all money held by it to the Trustee.
Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or
a Subsidiary) shall have no further liability for the money.  If the Issuer or
a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate
trust fund for the benefit of the Holders all money held by it as Paying Agent.





                                       16
<PAGE>   24
Upon any bankruptcy or reorganization proceedings relating to the Issuer, the
Trustee shall serve as Paying Agent for the Debentures.

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
all Holders and shall otherwise comply with TIA Section 312(a).  If the Trustee
is not the Registrar, the Issuer shall furnish to the Trustee at least seven
Business Days before each interest payment date and at such other times as the
Trustee may request, a list in such form and as of such date as the Trustee may
reasonably require of the names and addresses of the Holders of Debentures and
the Issuer shall otherwise comply with TIA Section 312(a).

SECTION 2.06.    TRANSFER AND EXCHANGE.

          (a)    Transfer and Exchange of Global Debentures.  A Global
Debenture may not be transferred as a whole except by the Depositary to a
nominee of the Depositary, by a nominee of the Depositary to the Depositary or
to another nominee of the Depositary, the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary.  All Global
Debentures will be exchanged by the Issuer for Definitive Debentures if (i) the
Issuer delivers to the Trustee notice from the Depositary that it is unwilling
or unable to continue to act as Depositary or that it is no longer a clearing
agency registered under the Exchange Act and, in either case, a successor
Depositary is not appointed by the Issuer within 120 days after the date of
such notice from the Depositary or (ii) the Issuer in its sole discretion
determines that the Global Debentures (in whole but not in part) should be
exchanged for Definitive Debentures and delivers a written notice to such
effect to the Trustee; provided that in no event shall the Regulation S
Temporary Global Debenture be exchanged by the Issuer for Definitive Debentures
prior to (x) the expiration of the Restricted Period and (y) the receipt by the
Registrar of any certificates required pursuant to Rule 903(c)(3)(ii)(B) under
the Securities Act.  Upon the occurrence of either of the preceding events in
(i) or (ii) above, Definitive Debentures shall be issued in such names as the
Depositary shall instruct the Trustee.  Global Debentures also may be exchanged
or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof.
Every Debenture authenticated and delivered in exchange for, or in lieu of, a
Global Debenture or any portion thereof, pursuant to this Section 2.06 or
Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form
of, and shall be, a Global Debenture.  A Global Debenture may not be exchanged
for another Debenture other than as provided in this Section 2.06(a), however,
beneficial interests in a Global Debenture may be transferred and exchanged as
provided in Section 2.06(b),(c) or (f) hereof.

          (b)    Transfer and Exchange of Beneficial Interests in the Global
Debentures.  The transfer and exchange of beneficial interests in the Global
Debentures shall be effected through the Depositary, in accordance with the
provisions of this Indenture and the Applicable Procedures.  Beneficial
interests in the Restricted Global Debentures shall be subject to restrictions
on transfer comparable to those set forth herein to the extent required by the
Securities Act.  Transfers of beneficial interests in the Global Debentures
also shall require compliance with either subparagraph (i) or (ii) below, as
applicable, as well as one or more of the other following subparagraphs, as
applicable:

                 (i)      Transfer of Beneficial Interests in the Same Global
             Debenture.  Beneficial interests in any Restricted Global
             Debenture may be transferred to Persons who take delivery thereof
             in the form of a beneficial interest in the same Restricted Global
             Debenture in accordance with the transfer restrictions set forth
             in the Private Placement Legend; provided, however, that prior to
             the expiration of the Restricted Period, transfers of beneficial
             interests in the Temporary Regulation S Global Debenture may not
             be made to a U.S. Person or for the account or benefit of a U.S.
             Person (other than an Initial Purchaser).  Beneficial interests in
             any Unrestricted Global Debenture may be transferred to Persons
             who take delivery thereof in the form of a beneficial interest in
             an Unrestricted Global Debenture.  No written orders or
             instructions shall be required to be delivered to the Registrar to
             effect the transfers described in this Section 2.06(b)(i).

                 (ii)     All Other Transfers and Exchanges of Beneficial
             Interests in Global Debentures.  In connection with all transfers
             and exchanges of beneficial interests that are not subject to
             Section 2.06(b)(i) above, the transferor of such beneficial
             interest must deliver to the Registrar either (A) (1) a written
             order from a Participant or an Indirect Participant given to the
             Depositary in accordance with the Applicable Procedures directing
             the Depositary to credit or cause to be credited a beneficial
             interest in another Global Debenture in an amount equal to the
             beneficial interest to be transferred or exchanged and (2)
             instructions given in accordance with the Applicable Procedures
             containing information regarding the Participant account to be
             credited with such increase or (B) (1) a written order from a
             Participant or an Indirect Participant given to the Depositary in
             accordance with the Applicable Procedures directing the Depositary
             to cause to be issued a Definitive Debenture in an amount equal to
             the beneficial interest to be transferred or exchanged and (2)
             instructions given by the Depositary to the Registrar containing
             information regarding the Person in whose name such Definitive
             Debenture shall be registered to effect the transfer or exchange
             referred to in (1) above; provided that in no event shall
             Definitive Debentures be issued upon the transfer or exchange of
             beneficial interests in the Regulation S Temporary Global
             Debenture prior to (x) the expiration of the Restricted Period and
             (y) the receipt by the Registrar of any certificates required
             pursuant to Rule 903 under the Securities Act.  Upon consummation
             of an Exchange Offer by the Issuer in accordance with Section
             2.06(f) hereof, the requirements of this Section 2.06(b)(ii) shall
             be deemed to have been satisfied upon receipt by the Registrar of
             the instructions contained in the Letter of Transmittal delivered
             by the Holder of such beneficial interests in the Restricted
             Global Debentures.  Upon satisfaction of all of the requirements
             for transfer or exchange of beneficial interests in Global
             Debentures contained in this Indenture and the Debentures or
             otherwise applicable under the Securities Act, the Trustee shall
             adjust the principal amount at maturity of the relevant Global
             Debenture(s) pursuant to Section 2.06(h) hereof.

                 (iii)    Transfer of Beneficial Interests to Another
             Restricted Global Debenture.  A beneficial interest in any
             Restricted Global Debenture may be transferred to a Person who
             takes delivery thereof in the form of a beneficial interest in
             another Restricted Global Debenture if the transfer complies with
             the requirements of Section 2.06(b)(ii) above and the Registrar
             receives the following:

                    (A)   if the transferee will take delivery in the form of a
                 beneficial interest in the 144A Global Debenture, then the
                 transferor must deliver a certificate in the form of Exhibit B
                 hereto, including the certifications in item (1) thereof; and

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

                 (iv)     Transfer and Exchange of Beneficial Interests in a
             Restricted Global Debenture for Beneficial Interests in the
             Unrestricted Global Debenture.  A beneficial interest in any
             Restricted Global Debenture may be exchanged by any holder thereof
             for a beneficial interest in an Unrestricted Global Debenture or
             transferred to a Person who takes delivery thereof in the form of
             a beneficial interest in an Unrestricted Global Debenture if the
             exchange or transfer complies with the requirements of Section
             2.06(b)(ii) above and:

                    (A)   such exchange or transfer is effected pursuant to the
                 Exchange Offer in accordance with the Registration Rights
                 Agreement and the holder of the beneficial interest to be
                 transferred, in the case of an exchange, or the transferee, in
                 the case of a transfer, certifies in the applicable Letter of
                 Transmittal that it is not (1) a broker-dealer, (2) a Person

                 or (3) a Person who is an affiliate (as defined in Rule 144)

                    (C)   such transfer is effected by a Participating
                 Broker-Dealer pursuant to the Exchange Offer Registration
                 Statement in accordance with the Registration Rights
                 Agreement; or

                    (D)   the Registrar receives the following:

                            (1)   if the holder of such beneficial interest in
                      a Restricted Global Debenture proposes to exchange such
                      beneficial interest for a beneficial interest in an
                      Unrestricted Global Debenture, a certificate from such
                      holder in the form of Exhibit C hereto, including the
                      certifications in item (1)(a) thereof; or

                            (2)   if the holder of such beneficial interest in
                      a Restricted Global Debenture proposes to transfer such
                      beneficial interest to a Person who shall take delivery

                      holder in the form of Exhibit B hereto, including the
                      certifications in item (4) thereof;

             and, in each such case set forth in this subparagraph (D), if the

             Registrar to the effect that such exchange or transfer is in
             compliance with the Securities Act and that the restrictions on
             transfer contained herein and in the Private Placement Legend are
             no longer required in order to maintain compliance with the
             Securities Act.

         If any such transfer is effected pursuant to subparagraph (B) or (D)
above at a time when an Unrestricted Global Debenture has not yet been issued,
the Issuer shall issue and, upon receipt of an Authentication Order in
accordance with Section 2.02 hereof, the Trustee shall authenticate one or more
Unrestricted Global Debentures in an aggregate principal amount at maturity
equal to the aggregate principal amount at maturity of beneficial interests
transferred pursuant to subparagraph (B) or (D) above.

         Beneficial interests in an Unrestricted Global Debenture cannot be
exchanged for, or transferred to Persons who take delivery thereof in the form
of, a beneficial interest in a Restricted Global Debenture.

          (c)    Transfer or Exchange of Beneficial Interests for Definitive

             Debenture, then, upon receipt by the Registrar of the following

Debentures to be reduced accordingly, and the Issuer shall execute and the

         THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO
         REGISTER ANY TRANSFER OF THIS SECURITY IN VIOLATION OF THE FOREGOING."

time as all beneficial interests in a particular Global Debenture have been
exchanged for Definitive Debentures or a particular Global Debenture has been
redeemed, repurchased or cancelled in whole and not in part, each such Global
Debenture shall be returned to or retained and cancelled by the Trustee in
accordance with Section 2.11 hereof.  At any time prior to such cancellation,
if any beneficial interest in a Global Debenture is exchanged for or
transferred to a Person who will take delivery thereof in the form of a
beneficial interest in another Global Debenture or for Definitive Debentures,

             similar governmental charge payable upon exchange or transfer
             pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05

                 (iii)    The Registrar shall not be required to register the
             transfer of or exchange any Debenture selected for redemption in
             whole or in part, except the unredeemed portion of any Debenture
             being redeemed in part.

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

                 (v)      The Issuer shall not be required (A) to issue, to
             register the transfer of or to exchange any Debentures during a
             period beginning at the opening of business 15 days before the day
             of any selection of Debentures for redemption under Section 3.02
             hereof and ending at the close of business on the day of
             selection, (B) to register the transfer of or to exchange any
             Debenture so selected for redemption in whole or in part, except
             the unredeemed portion of any Debenture being redeemed in part or
             (c) to register the transfer of or to exchange a Debenture between
             a record date and the next succeeding Interest Payment Date.

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

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

                 (viii)   All certifications, certificates and Opinions of
             Counsel required to be submitted to the Registrar pursuant to this
             Section 2.06 to effect a registration of transfer or exchange may
             be submitted by facsimile.

SECTION 2.07.    REPLACEMENT DEBENTURES

         If any Debenture is surrendered to the Trustee or the Issuer and the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Debenture, the Issuer shall issue and the Trustee, upon receipt of an
Authentication Order, shall authenticate a replacement Debenture if the
Trustee's requirements are met.  If required by the Trustee or the Issuer, an
indemnity bond must be supplied by the Holder that is sufficient in the
judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any
Agent and any authenticating agent from any loss that any of them may suffer if
a Debenture is replaced.  The Issuer may charge for its expenses in replacing a
Debenture.

         Every replacement Debenture is an additional obligation of the Issuer
and shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Debentures duly issued hereunder.

SECTION 2.08.    OUTSTANDING DEBENTURES.

         The Debentures outstanding at any time are all the Debentures
authenticated by the Trustee except for those cancelled by it, those delivered
to it for cancellation, those reductions in the interest in a Global Debenture
effected by the Trustee in accordance with the provisions hereof, and those
described in this Section as not outstanding.  Except as set forth in Section
2.09 hereof, a Debenture does not cease to be outstanding because the Issuer or
an Affiliate of the Issuer holds the Debenture; however, Debentures held by the
Issuer or a Subsidiary of the Issuer shall not be deemed to be outstanding for
purposes of Section 3.07(b) hereof.

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





                                       27
<PAGE>   35
         If the principal amount at maturity of any Debenture is considered
paid under Section 4.01 hereof, it ceases to be outstanding and interest on it
ceases to accrue.

         If the Paying Agent (other than the Issuer, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Debentures payable on that date, then on and after that date
such Debentures shall be deemed to be no longer outstanding and shall cease to
accrue interest.

SECTION 2.09.    TREASURY DEBENTURES.

         In determining whether the Holders of the required principal amount at
maturity of Debentures have concurred in any direction, waiver or consent,
Debentures owned by the Issuer, or by any Person directly or indirectly
controlling or controlled by or under direct or indirect common control with
the Issuer, shall be considered as though not outstanding, except that for the
purposes of determining whether the Trustee shall be protected in relying on
any such direction, waiver or consent, only Debentures that the Trustee knows
are so owned shall be so disregarded.

SECTION 2.10.    TEMPORARY DEBENTURES

         Until certificates representing Debentures are ready for delivery, the
Issuer may prepare and the Trustee, upon receipt of an Authentication Order,
shall authenticate temporary Debentures.  Temporary Debentures shall be
substantially in the form of certificated Debentures but may have variations
that the Issuer considers appropriate for temporary Debentures and as shall be
reasonably acceptable to the Trustee.  Without unreasonable delay, the Issuer
shall prepare and the Trustee shall authenticate definitive Debentures in
exchange for temporary Debentures.

         Holders of temporary Debentures shall be entitled to all of the
benefits of this Indenture.

SECTION 2.11.    CANCELLATION.

         The Issuer at any time may deliver Debentures to the Trustee for
cancellation.  The Registrar and Paying Agent shall forward to the Trustee any
Debentures surrendered to them for registration of transfer, exchange or
payment.  The Trustee and no one else shall cancel all Debentures surrendered
for registration of transfer, exchange, payment, replacement or cancellation
and shall destroy cancelled Debentures (subject to the record retention
requirement of the Exchange Act).  Certification of the destruction of all
cancelled Debentures shall be delivered to the Issuer.  The Issuer may not
issue new Debentures to replace Debentures that it has paid or that have been
delivered to the Trustee for cancellation.

SECTION 2.12.    DEFAULTED INTEREST.

         If the Issuer defaults in a payment of interest on the Debentures, it
shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are
Holders on a subsequent special record date, in each case at the rate provided
in the Debentures and in Section 4.01 hereof.  The Issuer shall notify the
Trustee in writing of the amount of defaulted interest proposed to be paid on
each Debenture and the date of the proposed payment.  The Issuer  shall fix or
cause to be fixed each such special record date and payment date, provided that
no such special record date shall be less than 10 days prior to the related
payment date for such defaulted interest.  At least 15 days before the special
record date, the Issuer (or, upon the written request of the Issuer, the
Trustee in the name and at the expense of the Issuer) shall mail or cause to be
mailed to Holders a notice that states the special record date, the related
payment date and the amount of such interest to be paid.

redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 45 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant
to which the redemption shall occur, (ii) the redemption date, (iii) the
principal amount at maturity of Debentures to be redeemed and (iv) the
redemption price.

SECTION 3.02.    SELECTION OF DEBENTURES TO BE REDEEMED

         If less than all of the Debentures are to be redeemed at any time,
selection of Debentures for redemption will be made by the Trustee in
compliance with the requirements of the principal national securities exchange,
if any, on which the Debentures are listed, or, if the Debentures are not so
listed, on a pro rata basis, by lot or by such method as the Trustee shall deem
fair and appropriate; provided that no Debentures having a principal amount at
maturity of $1,000 or less shall be redeemed in part.

         The Trustee shall promptly notify the Issuer in writing of the
Debentures selected for redemption and, in the case of any Debenture selected
for partial redemption, the principal amount at maturity thereof to be
redeemed.  Debentures and portions of Debentures selected shall be in amounts
of $1,000 or whole multiples of $1,000; except that if all of the Debentures of
a Holder are to be redeemed, the entire outstanding amount of Debentures held
by such Holder, even if not a multiple of $1,000, shall be redeemed.  Except as
provided in the preceding sentence, provisions of this Indenture that apply to
Debentures called for redemption also apply to portions of Debentures called
for redemption.

SECTION 3.03.    NOTICE OF REDEMPTION

         Subject to the provisions of Section 3.09 hereof, notices of
redemption shall be mailed by first class mail at least 30 but not more than 60
days before the redemption date to each Holder of Debentures to be redeemed at
its registered address.  If any Debentures is to be redeemed in part only, the
notice of redemption that relates to such Debentures shall state the portion of
the principal amount at maturity thereof to be redeemed. A new Debenture in
principal amount at maturity equal to the unredeemed portion thereof will be
issued in the name of the Holder thereof upon cancellation of the original
Debentures.  Debentures called for redemption become due on the date fixed for
redemption. On and after the redemption date, interest ceases to accrue on
Debentures or portions of them called for redemption.

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

          (a)    the redemption date;

          (b)    the redemption price;

          (c)    if any Debenture is being redeemed in part, the portion of the
principal amount at maturity of such Debenture to be redeemed and that, after
the redemption date upon surrender of such Debenture, a new Debenture or
Debentures in principal amount at maturity equal to the unredeemed portion
shall be issued upon cancellation of the original Debenture;

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

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





                                       29
<PAGE>   37
          (f)    that, unless the Issuer defaults in making such redemption
payment, interest on Debentures called for redemption ceases to accrue on and
after the redemption date;

          (g)    the paragraph of the Debentures and/or Section of this
Indenture pursuant to which the Debentures called for redemption are being
redeemed; and

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

         At the Issuer's request, the Trustee shall give the notice of
redemption in the Issuer's name and at its expense; provided, however, that the
Issuer shall have delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as
provided in the preceding paragraph.

SECTION 3.04.    EFFECT OF NOTICE OF REDEMPTION

         Once notice of redemption is mailed in accordance with Section 3.03
hereof, Debentures called for redemption become irrevocably due and payable on
the redemption date at the redemption price.  A notice of redemption may not be
conditional.

SECTION 3.05.    DEPOSIT OF REDEMPTION PRICE

         One Business Day prior to the redemption date, the Issuer shall
deposit with the Trustee or with the Paying Agent money sufficient to pay the
redemption price of and accrued interest on all Debentures to be redeemed on
that date.  The Trustee or the Paying Agent shall promptly return to the Issuer
any money deposited with the Trustee or the Paying Agent by the Issuer in
excess of the amounts necessary to pay the redemption price of, and accrued
interest on, all Debentures to be redeemed.

         If the Issuer complies with the provisions of the preceding paragraph,
on and after the redemption date, interest shall cease to accrue on the
Debentures or the portions of Debentures called for redemption.  If a Debenture
is redeemed on or after an interest record date but on or prior to the related
interest payment date, then any accrued and unpaid interest shall be paid to
the Person in whose name such Debenture was registered at the close of business
on such record date.  If any Debenture called for redemption shall not be so
paid upon surrender for redemption because of the failure of the Issuer to
comply with the preceding paragraph, interest shall be paid on the unpaid
principal, from the redemption date until such principal is paid, and to the
extent lawful on any interest not paid on such unpaid principal, in each case

         Notwithstanding the foregoing, on or prior to June 1, 2001, the Issuer
may redeem up to 40% of the aggregate principal amount at maturity of
Debentures ever issued under this Indenture in cash at a redemption price of
112.500% of the Accreted Value thereof, plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the redemption date, with the net cash
proceeds of one or more Public Equity Offerings; provided that, in the event
that the Issuer redeems less than 100% of the then outstanding Debentures, at
least 60% of the aggregate principal amount at maturity of the Debentures ever
issued under this Indenture remains outstanding immediately after the
occurrence of any such redemption; and provided further that such redemption
shall occur within 90 days of the date of the closing of any such Public Equity
Offering.

          In addition, at any time prior to June 1, 2003, the Issuer may, at
its option upon the occurrence of a Change of Control, redeem the Debentures,
in whole but not in part, upon not less than 30 nor more than 60 days' prior
notice (but in no event may any such redemption occur more than 60 days after
the occurrence of such Change of Control), in cash at a redemption price equal
to (i) the present value of the sum of all the remaining premium and principal
payments that would become due on the Debentures as if the Debentures were to
remain outstanding and be redeemed on June 1, 2003, computed using a discount
rate equal to the Treasury Rate plus 50 basis points, plus (ii) Liquidated
Damages, if any, to the date of redemption.

          (b)    Any redemption pursuant to this Section 3.07 shall be made
pursuant to the provisions of Section 3.01 through 3.06 hereof.

SECTION 3.08.    MANDATORY REDEMPTION.

         The Issuer is not required to make mandatory redemption of, or sinking
fund payments with respect to, the Debentures.

SECTION 3.09.    OFFER TO PURCHASE BY APPLICATION OF EXCESS PROCEEDS.

         In the event that, pursuant to Section 4.10 hereof, the Issuer shall
be required to commence an offer to all Holders to purchase Debentures (an
"Asset Sale Offer"), it shall follow the procedures specified below.

         The Asset Sale Offer shall remain open for a period of 20 Business
Days following its commencement and no longer, except to the extent that a
longer period is required by applicable law (the "Offer Period").  No later
than five Business Days after the termination of the Offer Period (the
"Purchase Date"), the Issuer shall purchase the principal amount at maturity of
Debentures required to be purchased pursuant to Section 4.10 hereof (the "Offer
Amount") or, if less than the Offer Amount has been tendered, all Debentures
tendered in response to the Asset Sale Offer.  Payment for any Debentures so
purchased shall be made in the same manner as interest payments are made.

         If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest shall
be paid to the Person in whose name a Debenture is registered at the close of
business on such record date, and no additional interest shall be payable to
Holders who tender Debentures pursuant to the Asset Sale Offer.

         Upon the commencement of an Asset Sale Offer, the Issuer shall send,
by first class mail, a notice to each of the Holders, with a copy to the
Trustee.  The notice shall contain all instructions and materials necessary to





                                       31
<PAGE>   39
enable such Holders to tender Debentures pursuant to the Asset Sale Offer.  The
Asset Sale Offer shall be made to all Holders.  The notice, which shall govern
the terms of the Asset Sale Offer, shall state:

          (a)    that the Asset Sale Offer is being made pursuant to this
Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale
Offer shall remain open;

          (b)    the Offer Amount, the purchase price and the Purchase Date;

          (c)    that any Debenture not tendered or accepted for payment shall
continue to accrete or accrue interest;

          (d)    that, unless the Issuer defaults in making such payment, any
Debenture accepted for payment pursuant to the Asset Sale Offer shall cease to
accrete or accrue interest after the Purchase Date;

          (e)    that Holders electing to have a Debenture purchased pursuant
to an Asset Sale Offer may only elect to have all of such Debenture purchased
and may not elect to have only a portion of such Debenture purchased;

          (f)    that Holders electing to have a Debenture purchased pursuant
to any Asset Sale Offer shall be required to surrender the Debenture, with the
form entitled "Option of Holder to Elect Purchase" on the reverse of the
Debenture completed, or transfer by book-entry transfer, to the Issuer, a
depositary, if appointed by the Issuer, or a Paying Agent at the address
specified in the notice at least three days before the Purchase Date;

          (g)    that Holders shall be entitled to withdraw their election if
the Issuer, the depositary or the Paying Agent, as the case may be, receives,
not later than the expiration of the Offer Period, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount at maturity of the Debenture the Holder delivered for purchase and a
statement that such Holder is withdrawing his election to have such Debenture
purchased;

          (h)    that, if the aggregate principal amount at maturity of
Debentures surrendered by Holders exceeds the Offer Amount, the Issuer shall
select the Debentures to be purchased on a pro rata basis (with such
adjustments as may be deemed appropriate by the Issuer so that only Debentures
in denominations of $1,000, or integral multiples thereof, shall be purchased);
and

          (i)    that Holders whose Debentures were purchased only in part
shall be issued new Debentures equal in principal amount at maturity to the
unpurchased portion of the Debentures surrendered (or transferred by book-entry
transfer).

         On or before the Purchase Date, the Issuer shall, to the extent
lawful, accept for payment, on a pro rata basis to the extent necessary, the
Offer Amount of Debentures or portions thereof tendered pursuant to the Asset
Sale Offer, or if less than the Offer Amount has been tendered, all Debentures
tendered, and shall deliver to the Trustee an Officers' Certificate stating
that such Debentures or portions thereof were accepted for payment by the
Issuer in accordance with the terms of this Section 3.09.  The Issuer, the
Depositary or the Paying Agent, as the case may be, shall promptly (but in any
case not later than five days after the Purchase Date) mail or deliver to each
tendering Holder an amount equal to the purchase price of the Debentures
tendered by such Holder and accepted by the Issuer for purchase, and the Issuer
shall promptly issue a new Debenture, and the Trustee, upon written request
from the Issuer shall authenticate and mail or deliver such new Debenture to
such Holder, in a principal amount at maturity equal to any unpurchased portion
of the Debenture surrendered.  Any Debenture not so accepted shall be promptly
mailed or delivered by the Issuer to the Holder thereof.  The Issuer shall
publicly announce the results of the Asset Sale Offer on the Purchase Date.

         Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

SECTION 4.01.    PAYMENT OF DEBENTURES.

         The Issuer shall pay or cause to be paid the principal of, premium, if
any, and interest on the Debentures on the dates and in the manner provided in
the Debentures.  Principal, premium, if any, and interest shall be considered
paid on the date due if the Paying Agent, if other than the Issuer or a
Subsidiary thereof, holds as of 10:00 a.m.  Eastern Time on the due date money
deposited by the Issuer in immediately available funds and designated for and
sufficient to pay all principal, premium, if any, and interest then due.  The
Issuer 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.

         The Issuer shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
1% per annum in excess of the then applicable interest rate on the Debentures
to the extent lawful; they shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue installments of interest
and Liquidated Damages (without regard to any applicable grace period) at the
same rate to the extent lawful.

SECTION 4.02.    MAINTENANCE OF OFFICE OR AGENCY.

         The Issuer shall maintain in the Borough of Manhattan, the City of New
York, an office or agency (which may be an office of the Trustee or an
affiliate of the Trustee, Registrar or co-registrar) where Debentures may be
surrendered for registration of transfer or for exchange and where notices and
demands to or upon the Issuer in respect of the Debentures and this Indenture
may be served.  The Issuer shall give prompt written notice to the Trustee of
the location, and any change in the location, of such office or agency.  If at
any time the Issuer shall fail to maintain any such required office or agency
or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee.

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

         The Issuer hereby designates the Corporate Trust Office of the Trustee
as one such office or agency of the Issuer in accordance with Section 2.03.

SECTION 4.03.    REPORTS.

          Whether or not required by the rules and regulations of the
Commission, so long as any Debentures are outstanding, the Issuer will furnish
to the Trustee and Holders of Debentures (a) 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 Issuer were required to file such
Forms, including a "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and, with respect to the annual information only, a
report thereon by the Issuer's certified independent accountants and (b) all
current reports that would be required to be filed with the Commission on Form

time periods specified in the Commission's rules and regulations. In addition,
following the consummation of the exchange offer contemplated by the
Registration Rights Agreement, whether or not required by the rules and
regulations of the Commission, the Issuer will file a copy of all such
information and reports with the Commission for public availability within the
time periods specified in the Commission's rules and regulations (unless the
Commission will not accept such a filing) and make such information available
to securities analysts and prospective investors upon request. In addition, the
Issuer has agreed that, for so long as any Debentures remain outstanding, it
will furnish to the Holders, the Trustee and to securities analysts and





                                       33

the end of each fiscal year, an Officers' Certificate stating that a review of
the activities of the Issuer and its Subsidiaries during the preceding fiscal
year have been made under the supervision of the signing Officers with a view
to determining whether the Issuer has kept, observed, performed and fulfilled
its obligations under this Indenture, and further stating, as to each such
Officer signing such certificate, that to the best of his or her knowledge the
Issuer has kept, observed, performed and fulfilled each and every covenant
contained in this Indenture and are not in default in the performance or
observance of any of the terms, provisions and conditions of this Indenture
(or, if a Default or Event of Default shall have occurred, describing all such
Defaults or Events of Default of which he or she may have knowledge and what
action the Issuer is taking or propose to take with respect thereto) and that
to the best of his or her knowledge no event has occurred and remains in
existence by reason of which payments on account of the principal of or
interest or Liquidated Damages, if any, on the Debentures are prohibited or if
such event has occurred, a description of the event and what action the Issuer
is taking or propose to take with respect thereto.

          (b)    So long as not contrary to the then current recommendations of
the American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 4.03(a) above shall be accompanied by
a written statement of the Issuer's independent public accountants (who shall
be a firm of established national reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Issuer has violated
any provisions of Article 4 or Article 5 hereof or, if any such violation has
occurred, specifying the nature and period of existence thereof, it being
understood that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such violation.

          (c)    The Issuer shall, so long as any of the Debentures are
outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware
of any Default or Event of Default, an Officers' Certificate specifying such
Default or Event of Default and what action the Issuer is taking or propose to
take with respect thereto.

SECTION 4.05.    TAXES.

         The Issuer shall pay, and shall cause each of its Subsidiaries to pay,
prior to delinquency, all material taxes, assessments, and governmental levies

where the failure to effect such payment is not adverse in any material respect
to the Holders of the Debentures.

SECTION 4.06.    STAY, EXTENSION AND USURY LAWS.

         The Issuer covenants (to the extent that they may lawfully do so) that
it shall 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, that may affect the covenants
or the performance of this Indenture; and the Issuer (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it shall not, by resort to any such law, hinder, delay
or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law has
been enacted.

SECTION 4.07.    RESTRICTED PAYMENTS.

         The Issuer will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, (a) declare or pay any dividend or
make any other payment or distribution on account of the Issuer's or any of its

distributions payable in Equity Interests (other than Disqualified Stock) of
the Issuer or dividends or distributions payable to the Issuer or any Wholly
Owned Restricted Subsidiary of the Issuer); (b) purchase, redeem or otherwise
acquire or retire for value any Equity

<PAGE>   42
Interests of the Issuer, any of its Restricted Subsidiaries or any other
Affiliate of the Issuer (other than any such Equity Interests owned by the
Issuer or any Restricted Subsidiary of the Issuer); (c) make any principal
payment on or with respect to, or purchase, redeem, defease or otherwise
acquire or retire for value, any Indebtedness of the Issuer (other than the
Debentures) that is pari passu or subordinated in right of payment to the
Debentures, except in accordance with the mandatory redemption or repayment
provisions set forth in the original documentation governing such Indebtedness
or in accordance with Section 4.10 hereof (but not pursuant to any mandatory
offer to repurchase upon the occurrence of any event); or (d) make any
Restricted Investment (all such payments and other actions set forth in clauses
(a) through (d) above being collectively referred to as "Restricted Payments"),
unless, at the time of and after giving effect to such Restricted Payment:

                 (i)      no Default or Event of Default shall have occurred
             and be continuing or would occur as a consequence thereof; and

                 (ii)     the Issuer would, immediately after giving pro forma
             effect thereto as if such Restricted Payment had been made at the
             beginning of the applicable four-quarter period, have been
             permitted to incur at least $1.00 of additional Indebtedness
             pursuant to the Fixed Charge Coverage Ratio test set forth in the
             first paragraph of Section 4.09 herein; and

                 (iii)    such Restricted Payment, together with the aggregate
             amount of all other Restricted Payments made by the Issuer and its
             Restricted Subsidiaries after the date of this Indenture
             (excluding Restricted Payments permitted by clauses (a) (to the
             extent that the declaration of any dividend referred to therein
             reduces amounts available for Restricted Payments pursuant to this
             clause (iii)), (b), (c), (e) through (g), (j), and (p) of the next
             succeeding paragraph), is less than the sum, without duplication,
             of (A) 50% of the Consolidated Net Income of the Issuer for the
             period (taken as one accounting period) commencing July 1, 1998 to
             the end of the Issuer's most recently ended fiscal quarter for
             which internal financial statements are available at the time of
             such Restricted Payment (or, if such Consolidated Net Income for
             such period is a deficit, less 100% of such deficit), plus (B)
             100% of the Qualified Proceeds received by the Issuer on or after
             the date of this Indenture from contributions to the Issuer's
             capital or from the issue or sale on or after the date of this
             Indenture of Equity Interests of the Issuer or of Disqualified
             Stock or convertible debt securities of the Issuer to the extent
             that they have been converted into such Equity Interests (other
             than Equity Interests, Disqualified Stock or convertible debt
             securities sold to a Subsidiary of the Issuer and other than
             Disqualified Stock or convertible debt securities that have been
             converted into Disqualified Stock), plus (C) the amount equal to
             the net reduction in Investments in Persons after the date of this
             Indenture who are not Restricted Subsidiaries (other than
             Permitted Investments) resulting from (x) Qualified Proceeds
             received as a dividend, repayment of a loan or advance or other
             transfer of assets (valued at the fair market value thereof) to
             the Issuer or any Restricted Subsidiary from such Persons, (y)
             Qualified Proceeds received upon the sale or liquidation of such
             Investment and (z) the redesignation of Unrestricted Subsidiaries
             (other than any Unrestricted Subsidiary designated as such
             pursuant to clause (k) or (o) of the following paragraph) whose
             assets are used or useful in, or which is engaged in, one or more
             Permitted Business as Restricted Subsidiaries (valued
             (proportionate to the Issuer's equity interest in such Subsidiary)
             at the fair market value of the net assets of such Subsidiary at
             the time of such redesignation).

         The foregoing provisions will not prohibit:

          (a)    the payment of any dividend within 60 days after the date of
declaration thereof, if at said date of declaration such payment would have
complied with the provisions of this Indenture;

or out of the net cash proceeds of the substantially concurrent sale (other
than to a Subsidiary of the Issuer) of, other Equity Interests of the Issuer
(other than any Disqualified Stock) (the "Refunding Capital Stock"), provided
that the amount of any such net cash proceeds that are utilized for any such
redemption, repurchase, retirement, defeasance or





                                       35
<PAGE>   43
other acquisition shall be excluded from clause (iii)(B) of the preceding
paragraph and (ii) if immediately prior to the retirement of Retired Capital
Stock, the declaration and payment of dividends thereon was permitted under
clause (f) of this paragraph, the declaration and payment of dividends on the
Refunding Capital Stock in an aggregate amount per year no greater than the
aggregate amount of dividends per annum that was declarable and payable on such
Retired Capital Stock immediately prior to such retirement; provided that, at
the time of the declaration of any such dividends, no Default or Event of
Default shall have occurred and be continuing or would occur as a consequence
thereof;

          (c)    the defeasance, redemption, repurchase, retirement or other
acquisition of Pari Passu Indebtedness or Subordinated Indebtedness with the
net cash proceeds from an incurrence of, or in exchange for, Permitted
Refinancing Indebtedness;

          (d)    the repurchase, redemption or other acquisition or retirement
for value of any Equity Interests of the Issuer or Thermadyne LLC held by any

Subsidiaries') management pursuant to any management equity subscription
agreement or stock option agreement, provided that the aggregate price paid for
all such repurchased, redeemed, acquired or retired Equity Interests shall not
exceed (x) $7.5 million in any calendar year (with unused amounts in any
calendar year being carried over to succeeding calendar years subject to a
maximum (without giving effect to the following clause (y)) of $15.0 million in
any calendar year), plus (y) the aggregate cash proceeds received by the Issuer
during such calendar year from any reissuance of Equity Interests by the Issuer
or Thermadyne LLC to members of management of the Issuer and its Restricted
Subsidiaries and (ii) no Default or Event of Default shall have occurred and be
continuing immediately after such transaction;

pro forma basis, the Fixed Charge Coverage Ratio for the Issuer for the most
recently ended four full fiscal quarters for which internal financial
statements are available immediately preceding the date of such issuance would
have been no less than 2.0 to 1;

          (g)    the payment of dividends or distributions by a Restricted
Subsidiary on any class of common stock or membership interests of such
Restricted Subsidiary if (i) such dividend or distribution is paid pro rata to
all holders of such class of common stock or membership interests and (ii) at
least 51% of such class of common stock or membership interests is held by the

each case, after giving effect to all subsequent reductions in the amount of
any Restricted Investment made pursuant to this clause (i), either as a result

to the Issuer's equity interest in such Subsidiary at the time of such
redesignation) at the fair market value of the net assets of such Subsidiary at
the time of such redesignation), in the case of clause (A) and (B), not to
exceed the amount of such Restricted Investment previously made pursuant to
this clause (k); provided that no Default or Event of Default shall have
occurred and be continuing immediately after making such Restricted Investment;

          (j)    the declaration and payment of dividends to holders of any
class or series of Disqualified Stock of the Issuer or any Restricted

<PAGE>   44
provided that no Default or Event of Default shall have occurred and be
continuing immediately after making such Restricted Payment;

          (k)    repurchases of Equity Interests deemed to occur upon exercise
of stock options if such Equity Interests represent a portion of the exercise
price of such options;

          (l)    the payment of dividends or distributions on the Issuer's
common stock or Thermadyne LLC's membership interests, following the first
public offering of the Issuer's common stock or Thermadyne LLC's membership
interests after the date of this Indenture, of up to 6.0% per annum of the net
proceeds received by the Issuer or Thermadyne LLC from such public offering,
other than, in each case, with respect to public offerings with respect to the
Issuer's common stock or Thermadyne LLC's membership interests or Holdings'
common stock registered on Form S-8; provided that no Default or Event of
Default shall have occurred and be continuing immediately after any such
payment of dividends or distributions;

          (m)    any other Restricted Payment which, together with all other
Restricted Payments made pursuant to this clause (m) since the date of this
Indenture, does not exceed $25.0 million (in each case, after giving effect to
all subsequent reductions in the amount of any Restricted Investment made
pursuant to this clause (m) either as a result of (i) the repayment or
disposition thereof for cash or (ii) the redesignation of an Unrestricted
Subsidiary as a Restricted Subsidiary (valued proportionate to the Issuer's
equity interest in such Subsidiary at the time of such redesignation) at the
fair market value of the net assets of such Subsidiary at the time of such
redesignation), in the case of clause (i) and (ii), not to exceed the amount of
such Restricted Investment previously made pursuant to this clause (m);
provided that no Default or Event of Default shall have occurred and be
continuing immediately after making such Restricted Payment;

          (n)    the pledge by the Issuer of the Capital Stock of an
Unrestricted Subsidiary of the Issuer to secure Non-Recourse Debt of such
Unrestricted Subsidiary;

          (o)    the purchase, redemption or other acquisition or retirement
for value of any Equity Interests of any Restricted Subsidiary issued after the
date of this Indenture, provided that the aggregate price paid for any such
repurchased, redeemed, acquired or retired Equity Interests shall not exceed
the sum of (i) the amount of cash and Cash Equivalents received by such
Restricted Subsidiary from the issue or sale thereof and (ii) any accrued
dividends thereon the payment of which would be permitted pursuant to clause
(l) above;

          (p)    distributions or payments of Receivables Fees; and

          (q)    the purchase, redemption or other acquisition or retirement
for value of rights issued pursuant to the Issuer's Rights Plan as in effect on
the date of the Indenture.

         The Board of Directors of the Issuer may designate any Restricted
Subsidiary (other than Thermadyne LLC and Thermadyne Capital) to be an
Unrestricted Subsidiary if such designation would not cause a Default. For
purposes of making such designation, all outstanding Investments by the Issuer
and its Restricted Subsidiaries (except to the extent repaid in cash) in the
Subsidiary so designated will be deemed to be Restricted Payments at the time
of such designation and will reduce the amount available for Restricted
Payments under the first paragraph of this covenant. All such outstanding
Investments will be deemed to constitute Restricted Investments in an amount
equal to the greater of (i) the net book value of such Investments at the time
of such designation and (ii) the fair market value of such Investments at the
time of such designation. Such designation will only be permitted if such
Restricted Investment would be permitted at such time and if such Restricted
Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

         The amount of (i) all Restricted Payments (other than cash) shall be
the fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Issuer or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment
and (ii) Qualified Proceeds (other than cash) shall be the fair market value on
the date of receipt thereof by the Issuer of such Qualified Proceeds. The fair
market value of any non-cash Restricted Payment shall be determined by the
Board of Directors whose resolution with respect thereto





                                       37
<PAGE>   45
shall be delivered to the Trustee. Not later than the date of making any
Restricted Payment, the Issuer shall deliver to the Trustee an Officers'
Certificate stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by this Section 4.07 were
computed.

SECTION 4.08.    DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING
                 SUBSIDIARIES.

         The Issuer will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to (a)(i) pay dividends or make any other distributions
to the Issuer or any of its Restricted Subsidiaries (A) on its Capital Stock or
(B) with respect to any other interest or participation in, or measured by, its
profits, or (ii) pay any Indebtedness owed to the Issuer or any of its
Restricted Subsidiaries, (b) make loans or advances to the Issuer or any of its
Restricted Subsidiaries or (c) transfer any of its properties or assets to the
Issuer or any of its Restricted Subsidiaries. However, the foregoing
restrictions will not apply to encumbrances or restrictions existing under or
by reason of (a) Existing Indebtedness as in effect on the date of this
Indenture, (b) the terms of any Indebtedness permitted by the Indenture to be
incurred by any Restricted Subsidiary of the Issuer, (c) this Indenture and the
Debentures, (d) applicable law and any applicable rule, regulation or order,
(e) any agreement or instrument of a Person acquired by the Issuer or any of
its Restricted Subsidiaries as in effect at the time of such acquisition
(except to the extent created in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person, or the properties
or assets of any Person, other than the Person, or the property or assets of
the Person, so acquired, provided that, in the case of Indebtedness, such
Indebtedness was permitted by the terms of this Indenture to be incurred, (f)
customary non-assignment provisions in leases entered into in the ordinary
course of business and consistent with past practices, (g) purchase money
obligations for property acquired in the ordinary course of business that
impose restrictions of the nature described in clause (e) above on the property
so acquired, (h) contracts for the sale of assets, including, without
limitation, customary restrictions with respect to a Subsidiary pursuant to an
agreement that has been entered into for the sale or disposition of all or
substantially all of the Capital Stock or assets of such Subsidiary, (i)
Permitted Refinancing Indebtedness, provided that the restrictions contained in
the agreements governing such Permitted Refinancing Indebtedness are, in the
good faith judgment of the Issuer's Board of Directors, not materially less
favorable, taken as a whole, to the Holders of the Debentures than those
contained in the agreements governing the Indebtedness being refinanced, (j)
secured Indebtedness otherwise permitted to be incurred pursuant to Sections
4.09 and 4.12 hereof that limit the right of the debtor to dispose of the
assets securing such Indebtedness, (k) restrictions on cash or other deposits
or net worth imposed by customers under contracts entered into in the ordinary
course of business, (l) other Indebtedness or Disqualified Stock of Restricted
Subsidiaries permitted to be incurred subsequent to the Issuance Date pursuant
to the provisions of Section 4.09 hereof, (m) customary provisions in joint
venture agreements and other similar agreements entered into in the ordinary
course of business, and (n) restrictions created in connection with any
Receivables Facility that, in the good faith determination of the Board of
Directors of the Issuer, are necessary or advisable to effect such Receivables
Facility.

SECTION 4.09.    INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK.

          (a)    the Issuer will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume,
guarantee or otherwise become directly or indirectly liable, contingently or
otherwise, with respect to (collectively, "incur") any Indebtedness (including
Acquired Indebtedness), (b) the Issuer will not, and will not permit any of its
Restricted Subsidiaries to, issue any shares of Disqualified Stock and (c) the
Issuer will not permit any of its Restricted Subsidiaries to issue any shares
of preferred stock; provided that the Issuer or any Restricted Subsidiary may
incur Indebtedness (including Acquired Indebtedness) or issue shares of
Disqualified Stock if the Fixed Charge Coverage Ratio for the Issuer's most
recently ended four full fiscal quarters for which internal financial
statements are available immediately preceding the date on which such
additional Indebtedness is incurred or such Disqualified Stock is issued would
have been at least 2.0 to 1, determined on a consolidated pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness had been incurred, or the Disqualified Stock had been
issued, as the case may be, at the beginning of such four-quarter period.

         The Issuer will not incur any Indebtedness that is contractually
subordinated in right of payment to any other Indebtedness of the Issuer unless
such Indebtedness is also contractually subordinated in right of payment to the
Debentures on substantially identical terms; provided that no Indebtedness of
the Issuer shall be deemed to be





                                       38
<PAGE>   46
contractually subordinated in right of payment to any other Indebtedness of the
Issuer solely by virtue of being unsecured.

         The provisions of the first paragraph of this covenant will not apply
to the incurrence of any of the following items of Indebtedness (collectively,
"Permitted Indebtedness"):

          (i)    the incurrence by the Issuer and its Restricted Subsidiaries
of Indebtedness under the New Credit Facility; provided that the aggregate
principal amount of all Indebtedness (with letters of credit being deemed to
have a principal amount equal to the maximum potential liability of the Issuer
and such Restricted Subsidiaries thereunder) then classified as having been
incurred in reliance upon this clause (i) that remains outstanding under the
New Credit Facility after giving effect to such incurrence does not exceed an
amount equal to $430.0 million;

          (ii)   the incurrence by the Issuer and its Restricted Subsidiaries
of Existing Indebtedness;

          (iii)  the incurrence by (A) the Issuer of Indebtedness represented
by the Debentures and this Indenture and (B) Thermadyne LLC and Thermadyne
Capital of Indebtedness represented by the Senior Subordinated Notes and the
Subordinated Note Indenture and Thermadyne LLC's Restricted Subsidiaries of
Indebtedness represented by the guarantees thereof;

          (iv)   the incurrence by the Issuer or any of its Restricted
Subsidiaries of Indebtedness represented by Capital Expenditure Indebtedness,
Capital Lease Obligations or purchase money obligations, in each case, incurred
for the purpose of financing all or any part of the purchase price or cost of
construction or improvement of property, plant or equipment used in the
business of the Issuer or such Restricted Subsidiary, in an aggregate principal
amount (or accreted value, as applicable) not to exceed $40.0 million
outstanding after giving effect to such incurrence;

          (v)    Indebtedness arising from agreements of the Issuer or any
Restricted Subsidiary providing for indemnification, adjustment of purchase
price or similar obligations, in each case, incurred or assumed in connection
with the disposition of any business, assets or a Subsidiary, other than
guarantees of Indebtedness incurred by any Person acquiring all or any portion
of such business, assets or Restricted Subsidiary for the purpose of financing
such acquisition; provided that (A) such Indebtedness is not reflected on the
balance sheet of the Issuer or any Restricted Subsidiary (contingent
obligations referred to in a footnote or footnotes to financial statements and
not otherwise reflected on the balance sheet will not be deemed to be reflected
on such balance sheet for purposes of this clause (A)) and (B) the maximum
assumable liability in respect of such Indebtedness shall at no time exceed the
gross proceeds including non-cash proceeds (the fair market value of such
non-cash proceeds being measured at the time received and without giving effect
to any subsequent changes in value) actually received by the Issuer and/or such
Restricted Subsidiary in connection with such disposition;

          (vi)   the incurrence by the Issuer or any of its Restricted
Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net
proceeds of which are used to refund, refinance or replace Indebtedness (other
than intercompany Indebtedness) that was permitted by this Indenture to be
incurred;

          (vii)  the incurrence by the Issuer or any of its Restricted
Subsidiaries of intercompany Indebtedness between or among the Issuer and/or
any of its Restricted Subsidiaries; provided that (i) if the Issuer is the
obligor on such Indebtedness, such Indebtedness is expressly subordinated to
the prior payment in full in cash of all Obligations with respect to the
Debentures and (ii)(A) any subsequent issuance or transfer of Equity Interests
that results in any such Indebtedness being held by a Person other than the
Issuer or a Restricted Subsidiary thereof and (B) any sale or other transfer of
any such Indebtedness to a Person that is not either the Issuer or a Restricted
Subsidiary thereof shall be deemed, in each case, to constitute an incurrence
of such Indebtedness by the Issuer or such Restricted Subsidiary, as the case
may be, that was not permitted by this clause (vii);

          (viii) the incurrence by the Issuer or any of its Restricted
Subsidiaries of Hedging Obligations that are incurred for the purpose of fixing
or hedging (A) interest rate risk with respect to any floating rate
Indebtedness that is permitted by the terms of this Indenture to be outstanding
and (B) exchange rate risk with respect to agreements or Indebtedness of such
Person payable denominated in a currency other than U.S. dollars, provided that
such agreements





                                       39
<PAGE>   47
do not increase the Indebtedness of the obligor outstanding at any time other
than as a result of fluctuations in foreign currency exchange rates or interest
rates or by reason of fees, indemnities and compensation payable thereunder;

          (ix)   the guarantee by the Issuer or any of its Restricted
Subsidiaries of Indebtedness of the Issuer or a Restricted Subsidiary of the
Issuer that was permitted to be incurred by another provision of this covenant;

          (x)    the incurrence by the Issuer or any of its Restricted
Subsidiaries of Acquired Indebtedness in an aggregate principal amount (or
accreted value, as applicable) not to exceed $25.0 million outstanding after
giving effect to such incurrence;

          (xi)   obligations in respect of performance and surety bonds and
completion guarantees provided by the Issuer or any Restricted Subsidiary in
the ordinary course of business; and

          (xii)  the incurrence by the Issuer or any of its Restricted
Subsidiaries of additional Indebtedness in an aggregate principal amount (or
accreted value, as applicable) outstanding after giving effect to such
incurrence, including all Permitted Refinancing Indebtedness incurred to
refund, refinance or replace any Indebtedness incurred pursuant to this clause
(xii), not to exceed $50.0 million.

         For purposes of determining compliance with this covenant, in the
event that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Indebtedness described in clauses (i) through (xii)
above or is entitled to be incurred pursuant to the first paragraph of this
covenant, the Issuer shall, in its sole discretion, classify such item of
Indebtedness in any manner that complies with this covenant and such item of
Indebtedness will be treated as having been incurred pursuant to only one of
such clauses or pursuant to the first paragraph hereof. In addition, the Issuer
may, at any time, change the classification of an item of Indebtedness (or any
portion thereof) to any other clause or to the first paragraph hereof provided
that the Issuer would be permitted to incur such item of Indebtedness (or such
portion thereof) pursuant to such other clause or the first paragraph hereof,
as the case may be, at such time of reclassification. Accrual of interest,
accretion or amortization of original issue discount will not be deemed to be
an incurrence of Indebtedness for purposes of this covenant.

         All Indebtedness under the New Credit Facility outstanding on the date
on which Debentures are first issued and authenticated under this Indenture
shall be deemed to have been incurred on such date in reliance on the first
paragraph of Section 4.09 hereof.

SECTION 4.10.    ASSET SALES

         The Issuer shall not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless (a) the Issuer or such
Restricted Subsidiary, as the case may be, receives consideration at the time
of such Asset Sale at least equal to the fair market value (evidenced by a
resolution of the board of directors set forth in an Officers' Certificate
delivered to the Trustee) of the assets or Equity Interests issued or sold or
otherwise disposed of and (b) at least 75% of the consideration therefor
received by the Issuer or such Restricted Subsidiary is in the form of (i) cash
or Cash Equivalents or (ii) property or assets that are used or useful in a
Permitted Business, or the Capital Stock of any Person engaged in a Permitted
Business if, as a result of the acquisition by the Issuer or any Restricted
Subsidiary thereof, such Person becomes a Restricted Subsidiary; provided that
the amount of (x) any liabilities (as shown on the Issuer's or such Restricted
Subsidiary's most recent balance sheet), of the Issuer or any Restricted
Subsidiary (other than contingent liabilities and liabilities that are by their
terms subordinated to the Debentures or any guarantee thereof) that are assumed
by the transferee of any such assets pursuant to a customary novation agreement
that releases the Issuer or such Restricted Subsidiary from further liability,
(y) any securities, notes or other obligations received by the Issuer or any
such Restricted Subsidiary from such transferee that are contemporaneously
(subject to ordinary settlement periods) converted by the Issuer or such
Restricted Subsidiary into cash or Cash Equivalents (to the extent of the cash
or Cash Equivalents received), and (z) any Designated Noncash Consideration
received by the Issuer or any of its Restricted Subsidiaries in such Asset Sale
having an aggregate fair market value, taken together with all other Designated
Noncash Consideration received pursuant to this clause (z) that is at that time
outstanding, not to exceed 15% of Total Assets at the time of the receipt of
such Designated Noncash Consideration (with the fair market value of each item
of Designated Noncash Consideration being measured at the time received and
without giving effect to





                                       40
<PAGE>   48
subsequent changes in value), shall be deemed to be cash for purposes of this
provision; and provided further that the 75% limitation referred to in clause
(b) above will not apply to any Asset Sale in which the cash or Cash
Equivalents portion of the consideration received therefrom, determined in
accordance with the foregoing proviso, is equal to or greater than what the
after-tax proceeds would have been had such Asset Sale complied with the
aforementioned 75% limitation.

         Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, the Issuer or any such Restricted Subsidiary shall apply such Net
Proceeds, at its option, to (a) repay or purchase Pari Passu Indebtedness of
the Issuer or any Indebtedness of any Restricted Subsidiary, provided that, if
the Issuer shall so repay or purchase Pari Passu Indebtedness of the Issuer, it
will equally and ratably reduce Indebtedness under the Debentures if the
Debentures are then redeemable, or, if the Debentures may not then be redeemed,
the Issuer shall make an offer (in accordance with the procedures set forth
below for an Asset Sale Offer) to all Holders of Debentures to purchase at a
purchase price equal to 100% of the principal amount at maturity of the
Debentures (or, in the case of purchases of Debentures prior to June 1, 2003,
at a purchase price equal to 100% of the Accreted Value thereof), plus accrued
and unpaid interest and Liquidated Damages, if any, thereon to the date of
purchase, the Debentures that would otherwise be redeemed, or (b) an investment
in property, the making of a capital expenditure or the acquisition of assets
that are used or useful in a Permitted Business, or Capital Stock of any Person
primarily engaged in a Permitted Business if (i) as a result of the acquisition
by the Issuer or any Restricted Subsidiary thereof, such Person becomes a
Restricted Subsidiary or (ii) the Investment in such Capital Stock is permitted
by clause (f) of the definition of Permitted Investments. Pending the final
application of any such Net Proceeds, the Issuer may temporarily reduce
Indebtedness or otherwise invest such Net Proceeds in any manner that is not
prohibited by this Indenture. Any Net Proceeds from Asset Sales that are not
applied or invested as provided in the first sentence of this paragraph will be
deemed to constitute "Excess Proceeds." When the aggregate amount of Excess
Proceeds exceeds $15.0 million, the Issuer will be required to make an offer to
all Holders of Debentures (an "Asset Sale Offer") to purchase the maximum
principal amount at maturity of Debentures that may be purchased out of the
Excess Proceeds, at an offer price in cash in an amount equal to 100% of the
principal amount at maturity thereof, plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the date of purchase (or, in the case of
repurchases of Debentures prior to June 1, 2003, at a purchase price equal to
100% of the Accreted Value, plus Liquidated Damages, if any thereon as of the
date of repurchase), in accordance with the procedures set forth in this
Indenture. To the extent that any Excess Proceeds remain after consummation of
an Asset Sale Offer, the Issuer may use such Excess Proceeds for any purpose
not otherwise prohibited by this Indenture. If the aggregate principal amount
at maturity or Accreted Value (as applicable) of Debentures surrendered by
Holders thereof in connection with an Asset Sale Offer exceeds the amount of
Excess Proceeds, the Trustee shall select the Debentures to be purchased as set
forth in Section 3.02 hereof.  Upon completion of such offer to purchase, the
amount of Excess Proceeds shall be reset at zero.

         The Issuer 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 the Debentures pursuant to an Asset Sale Offer. To the extent
that the provisions of any securities laws or regulations conflict with the
provisions of this Indenture relating to such Asset Sale Offer, the Issuer will
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations described in this Indenture by virtue
thereof.

SECTION 4.11.    TRANSACTIONS WITH AFFILIATES.

         The Issuer shall not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate of the Issuer (each of the foregoing, an "Affiliate
Transaction"), unless (a) such Affiliate Transaction is on terms that are no
less favorable to the Issuer or such Restricted Subsidiary than those that
would have been obtained in a comparable transaction by the Issuer or such
Restricted Subsidiary with an unrelated Person and (b) the Issuer delivers to
the Trustee, with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $7.5
million, either (i) a resolution of the board of directors set forth in an
Officers' Certificate certifying that such Affiliate Transaction complies with
clause (a) above and that such Affiliate Transaction has been approved by a
majority of the disinterested members of the board of directors or (ii) an
opinion as





                                       41
<PAGE>   49
to the fairness to the Holders of such Affiliate Transaction from a financial
point of view issued by an accounting, appraisal or investment banking firm of
national standing.

         Notwithstanding the foregoing, the following items shall not be deemed
to be Affiliate Transactions: (a) customary directors' fees, indemnification or
similar arrangements or any employment agreement or other compensation plan or
arrangement entered into by the Issuer or any of its Restricted Subsidiaries in
the ordinary course of business (including ordinary course loans to employees
not to exceed (i) $5.0 million outstanding in the aggregate at any time and
(ii) $2.0 million to any one employee) and consistent with the past practice of
the Issuer or such Restricted Subsidiary; (b) transactions between or among the
Issuer and/or its Restricted Subsidiaries; (c) payments of customary fees by
the Issuer or any of its Restricted Subsidiaries to DLJMB and its Affiliates
made for any financial advisory, financing, underwriting or placement services
or in respect of other investment banking activities, including, without
limitation, in connection with acquisitions or divestitures which are approved
by a majority of the board of directors in good faith; (d) any agreement as in
effect on the date of this Indenture or any amendment thereto (so long as such
amendment is not disadvantageous to the Holders of the Debentures in any
material respect) or any transaction contemplated thereby; (e) payments and
transactions in connection with the Merger, the New Credit Facility (including
commitment, syndication and arrangement fees payable thereunder) and the
Offerings (including underwriting discounts and commissions in connection
therewith) and the application of the proceeds thereof, and the payment of the
fees and expenses with respect thereto; (f) Restricted Payments that are
permitted by Section 4.07; (g) sales of accounts receivable, or participations
therein, in connection with any Receivables Facility; and (h) transactions
pursuant to the Management Loans.

SECTION 4.12.    LIENS.

         The Issuer shall not and will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, assume or
suffer to exist any Lien, other than a Permitted Lien, that secures obligations
under any Pari Passu Indebtedness or Subordinated Indebtedness of the Issuer on
any asset or property now owned or hereafter acquired by the Issuer or any of
its Restricted Subsidiaries, or any income or profits therefrom or assign or
convey any right to receive income therefrom, unless the Debentures are equally
and ratably secured with the obligations so secured until such time as such
obligations are no longer secured by a Lien.

SECTION 4.13.    CORPORATE EXISTENCE.

         Subject to Article 5 hereof, the Issuer shall do or cause to be done
all things necessary to preserve and keep in full force and effect (i) the
corporate, partnership or other existence of itself and each of its
Subsidiaries, in accordance with the respective organizational documents (as
the same may be amended from time to time) of the Issuer or any such Subsidiary
and (ii) the rights (charter and statutory), licenses and franchises of the
Issuer and its Subsidiaries; provided, however, that the Issuer shall not be
required to preserve any such right, license or franchise, or the corporate,
partnership or other existence of itself and any of its Subsidiaries, if the
Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Issuer and its Subsidiaries,
taken as a whole, and that the loss thereof is not adverse in any material
respect to the Holders of the Debentures.

SECTION 4.14.    OFFER TO REPURCHASE UPON CHANGE OF CONTROL.

          (a)    Upon the occurrence of a Change of Control, each Holder of
Debentures will have the right to require the Issuer to repurchase all or any
part (equal to $1,000 principal amount at maturity or an integral multiple
thereof) of such Holder's Debentures pursuant to the offer described below (the
"Change of Control Offer") at an offer price in cash equal to 101% of the
aggregate principal amount at maturity thereof, plus accrued and unpaid
interest and Liquidated Damages, if any, thereon to the date of repurchase (or,
in the case of repurchases of Debentures prior to June 1, 2003, at a purchase
price equal to 101% of the Accreted Value thereof, plus Liquidated Damages, if
any, thereon as of the date of redemption) (the "Change of Control Payment").
Within 65 days following any Change of Control, the Issuer will (or will cause
the Trustee to) mail a notice to each Holder describing the transaction or
transactions that constitute the Change of Control and offering to repurchase
Debentures, pursuant to the procedures required by this Indenture and described
in such notice. The Issuer 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 the Debentures as a result of a Change of Control. To the extent
that the provisions of any securities laws or regulations conflict with the
provisions of this Indenture relating to such Change of Control Offer, the
Issuer will comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations described in this
Indenture by virtue thereof.

          On the Change of Control Payment Date, the Issuer will, to the extent
lawful, (a) accept for payment all Debentures or portions thereof properly
tendered pursuant to the Change of Control Offer, (b) deposit with the Paying
Agent an amount equal to the Change of Control Payment in respect of all
Debentures or portions thereof so tendered and (c) deliver or cause to be
delivered to the Trustee the Debentures so accepted together with an Officers'
Certificate stating the aggregate principal amount at maturity of Debentures or
portions thereof being purchased by the Issuer. The Paying Agent will promptly
mail to each Holder of Debentures so tendered the Change of Control Payment for
such Debentures, and the Trustee will promptly authenticate and mail (or cause
to be transferred by book-entry) to each Holder a new Debenture equal in
principal amount at maturity to any unpurchased portion of the Debentures
surrendered, if any; provided that each such new Debenture will be in a
principal amount at maturity of $1,000 or an integral multiple thereof. Prior
to complying with the provisions of this covenant, but in any event within 90
days following a Change of Control, the Issuer will either repay all
outstanding Indebtedness or obtain the requisite consents, if any, under all
agreements governing outstanding Indebtedness to permit the repurchase of
Debentures required by this covenant.  The Issuer will publicly announce the
results of the Change of Control Offer on or as soon as practicable after the
Change of Control Payment Date.

         (b)     Notwithstanding anything to the contrary in this Section 4.15,
the Issuer will not be required to make a Change of Control Offer upon a Change
of Control if a third party makes the Change of Control Offer in the manner, at
the times and otherwise in compliance with the requirements set forth in this
Indenture applicable to a Change of Control Offer made by the Issuer and
purchases all Debentures validly tendered and not withdrawn under such Change
of Control Offer.

SECTION 4.15.    ACCOUNTS RECEIVABLE FACILITY.

         No Accounts Receivable Subsidiary will incur any Indebtedness if
immediately after giving effect to such incurrence the aggregate outstanding
Indebtedness of all Accounts Receivable Subsidiaries (excluding any
Indebtedness owed to the Issuer or any Restricted Subsidiary) would exceed
$60.0 million.

SECTION 4.16.    LIMITATION ON SALE AND LEASEBACK TRANSACTIONS.

         The Issuer will not, and will not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; provided that
the Issuer or any Restricted Subsidiary may enter into a sale and leaseback
transaction if (a) the Issuer or such Restricted Subsidiary, as the case may
be, could have (i) incurred Indebtedness in an amount equal to the Attributable
Indebtedness relating to such sale and leaseback transaction pursuant to the
Fixed Charge Coverage Ratio test set forth in the first paragraph of Section
4.09 hereof and (ii) incurred a Lien to secure such Indebtedness pursuant to
Section 4.12 herein, (b) the gross cash proceeds of such sale and leaseback
transaction are at least equal to the fair market value (as determined in good
faith by the board of directors and set forth in an Officers' Certificate
delivered to the Trustee) of the property that is the subject of such sale and
leaseback transaction and (c) the transfer of assets in such sale and leaseback
transaction is permitted by, and the Issuer applies the proceeds of such
transaction in compliance with, Section 4.10 hereof.

SECTION 4.17.    PAYMENTS FOR CONSENT.

         Neither the Issuer 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 Debentures for or as an
inducement to any consent, waiver or amendment of any of the terms or
provisions of this Indenture or the Debentures unless such consideration is
offered to be paid or is paid to all Holders of the Debentures that consent,
waive or agree to amend in the time frame set forth in the solicitation
documents relating to such consent, waiver or agreement.

SECTION 5.01.    MERGER, CONSOLIDATION, OR SALE OF ASSETS.

         The Issuer may not consolidate or merge with or into (whether or not
the Issuer is the surviving corporation), or sell, assign, transfer, convey or
otherwise dispose of all or substantially all of its properties or assets in
one or more related transactions, to another Person unless (a) the Issuer is
the surviving corporation or the Person formed by or surviving any such
consolidation or merger (if other than the Issuer) or to which such sale,
assignment, transfer, conveyance or other disposition shall have been made is a
corporation organized or existing under the laws of the United States, any
state thereof or the District of Columbia, (b) the Person formed by or
surviving any such consolidation or merger (if other than the Issuer) or the
Person to which such sale, assignment, transfer, conveyance or other
disposition shall have been made assumes all the obligations of the Issuer
under the Registration Rights Agreement, the Debentures and this Indenture
pursuant to a supplemental indenture in a form reasonably satisfactory to the
Trustee, (c) immediately after such transaction no Default or Event of Default
exists and (d) the Issuer or the Person formed by or surviving any such
consolidation or merger (if other than the Issuer), or to which such sale,
assignment, transfer, conveyance or other disposition shall have been made (i)
will, at the time of such transaction and after giving pro forma effect thereto
as if such transaction had occurred at the beginning of the applicable
four-quarter period, be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the
first paragraph of Section 4.09 hereof or (ii) would (together with its
Restricted Subsidiaries) have a higher Fixed Charge Coverage Ratio immediately
after such transaction (after giving pro forma effect thereto as if such
transaction had occurred at the beginning of the applicable four-quarter
period) than the Fixed Charge Coverage Ratio of the Issuer and its Restricted
Subsidiaries immediately prior to such transaction. The foregoing clause (d)
will not prohibit (a) a merger between the Issuer and an Affiliate of the
Issuer created for the purpose of holding the Capital Stock of the Issuer, (b)
a merger between the Issuer and a Wholly Owned Restricted Subsidiary or (c) a
merger between the Issuer and an Affiliate incorporated solely for the purpose
of reincorporating the Issuer in another State of the United States so long as,
in each case, the amount of Indebtedness of the Issuer and its Restricted
Subsidiaries is not increased thereby.  The Issuer shall not lease all or
substantially all of its assets to any Person.

SECTION 5.02.    SUCCESSOR CORPORATION SUBSTITUTED.

         Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the
assets of the Issuer in accordance with Section 5.01 hereof, the successor
corporation formed by such consolidation or into or with which the Issuer is
merged or to which such sale, assignment, transfer, lease, conveyance or other
disposition is made shall succeed to, and be substituted for (so that from and
after the date of such consolidation, merger, sale, lease, conveyance or other
disposition, the provisions of this Indenture referring to the "Issuer" shall
refer instead to the successor corporation and not to the Issuer), and may
exercise every right and power of the Issuer under this Indenture with the same
effect as if such successor Person had been named as the Issuer herein;
provided, however, that the predecessor Issuer shall not be relieved from the
obligation to pay the principal of and interest and Liquidated Damages, if any,
on the Debentures except in the case of a sale of all of the Issuer's assets
that meets the requirements of Section 5.01 hereof.

SECTION 6.01.    EVENTS OF DEFAULT.

         Each of the following constitutes an Event of Default:

<PAGE>   52
          (c)    failure by the Issuer or any of its Restricted Subsidiaries
for 30 days after receipt of notice from the Trustee or Holders of at least 25%
in principal amount at maturity of the Debentures then outstanding to comply
with Sections 4.07, 4.09, 4.10, 4.14 or Article 5 hereof;

          (d)    failure by the Issuer for 60 days after notice from the
Trustee or the Holders of at least 25% in principal amount at maturity of the
Debentures then outstanding to comply with any of its other agreements in this
Indenture or the Debentures;

          (e)    default under any mortgage, indenture or instrument under
which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Issuer or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Issuer or any of its
Restricted Subsidiaries), whether such Indebtedness or guarantee now exists, or
is created after the date of this Indenture, which default (i) is caused by a
failure to pay Indebtedness at its stated final maturity (after giving effect
to any applicable grace period provided in such Indebtedness) (a "Payment
Default") or (ii) results in the acceleration of such Indebtedness prior to its
stated final maturity and, in each case, the principal amount of any such
Indebtedness, together with the principal amount of any other such Indebtedness
under which there has been a Payment Default or the maturity of which has been
so accelerated, aggregates $10.0 million or more;

          (f)    failure by the Issuer or any of its Restricted Subsidiaries to
pay final judgments aggregating in excess of $10.0 million (net of any amounts
with respect to which a reputable and creditworthy insurance company has
acknowledged liability in writing), which judgments are not paid, discharged or
stayed for a period of 60 days; and

          (g)    the Issuer or any of its Restricted Subsidiaries that is a
Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a
whole, would constitute a Significant Subsidiary pursuant to or within the
meaning of Bankruptcy Law:

                 (i)      commences a voluntary case,

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

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

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

                 (v)      generally is not paying its debts as they become due;
             or

          (h)    a court of competent jurisdiction enters an order or decree

                 (vi)     is for relief against the Issuer or any of its
             Restricted Subsidiaries that is Significant Subsidiary or any
             group of Restricted Subsidiaries that, taken as a whole, would
             constitute a Significant Subsidiary in an involuntary case;

                 (vii)    appoints a Custodian of the Issuer or any of its
             Restricted Subsidiaries that is Significant Subsidiary or any
             group of Restricted Subsidiaries that, taken as a whole, would
             constitute a Significant Subsidiary or for all or substantially
             all of the property of the Issuer or any of its Restricted
             Subsidiaries that is a Significant Subsidiary or any group of
             Subsidiaries that, taken as a whole, would constitute a
             Significant Subsidiary; or

                 (viii)   orders the liquidation of the Issuer or any of its
             Restricted Subsidiaries that is a Significant Subsidiary or any
             group of Restricted Subsidiaries that, taken as a whole, would
             constitute a Significant Subsidiary;

          and the order or decree remains unstayed and in effect for 60
consecutive days.

SECTION 6.02.    ACCELERATION.

         If any Event of Default (other than an Event of Default specified in
clause (g) or (h) of Section 6.01 hereof with respect to the Issuer, any of its
Restricted Subsidiaries that is a Significant Subsidiary or any group of
Restricted Subsidiaries that, taken as a whole, would constitute a Significant
Subsidiary) occurs and is continuing, the Trustee or the Holders of at least
25% in principal amount at maturity of the then outstanding Debentures may
declare all the Debentures to be due and payable immediately; provided, that so
long as any Indebtedness permitted to be incurred pursuant to the New Credit
Facility shall be outstanding, such acceleration shall not be effective until
the earlier of (i) an acceleration under any such Indebtedness under the New
Credit Facility or (ii) five Business Days after receipt by the Issuer and the
administrative agent under the New Credit Facility of written notice of such
acceleration.  Upon any such declaration, the Debentures shall become due and
payable immediately.  Notwithstanding the foregoing, if an Event of Default
specified in clause (g) or (h) of Section 6.01 hereof occurs with respect to
the Issuer, any of its Restricted Subsidiaries that is a Significant Subsidiary
or any group of Restricted Subsidiaries that, taken as a whole, would
constitute a Significant Subsidiary, all outstanding Debentures shall be due
and payable immediately without further action or notice.  The Holders of a
majority in aggregate principal amount at maturity of the then outstanding
Debentures by written notice to the Trustee may on behalf of all of the Holders
rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal, interest or premium that has become due solely
because of the acceleration) have been cured or waived, provided that in the
event of a declaration of acceleration of the Debentures because an Event of
Default has occurred and is continuing as a result of the acceleration of any
Indebtedness described in clause (e) of Section 6.01 hereof, the declaration of
acceleration of the Debentures shall be automatically annulled if the holders
of any Indebtedness described in clause (e) of Section 6.01 hereof have
rescinded the declaration of acceleration in respect of such Indebtedness
within 30 days of the date of such declaration and if (i) the annulment of the
acceleration of the Debentures would not conflict with any judgment or decree
of a court of competent jurisdiction and (ii) all existing Events of Default,
except non-payment of principal or interest on the Debentures that became due
solely because of the acceleration of the Debentures, have been cured or
waived.

SECTION 6.03.    OTHER REMEDIES.

         If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of principal, premium, if
any, and interest and Liquidated Damages, if any, on the Debentures or to
enforce the performance of any provision of the Debentures or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Debentures or does not produce any of them in the proceeding.  A delay
or omission by the Trustee or any Holder of a Debenture 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.  All
remedies are cumulative to the extent permitted by law.

SECTION 6.04.    WAIVER OF PAST DEFAULTS.

         Holders of not less than a majority in principal amount at maturity of
the then outstanding Debentures by notice to the Trustee may on behalf of the
Holders of all of the Debentures waive an existing Default or Event of Default
and its consequences hereunder, except a continuing Default or Event of Default
in the payment of the principal of, premium and Liquidated Damages, if any, or
interest on, the Debentures (including in connection with an offer to purchase)
(provided, however, that the Holders of a majority in aggregate principal
amount at maturity of the then outstanding Debentures may rescind an
acceleration and its consequences, including any related payment default that
resulted from such acceleration).  Upon any such waiver, such Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereon.

<PAGE>   54
SECTION 6.05.    CONTROL BY MAJORITY.

         Holders of not less than a majority in principal amount at maturity of
the then outstanding Debentures may direct the time, method and place of
conducting any proceeding for exercising any remedy available to the Trustee or
exercising any trust or power conferred on it.  However, the Trustee may refuse
to follow any direction that conflicts with law or this Indenture that the
Trustee determines may be unduly prejudicial to the rights of other Holders of
Debentures or that may involve the Trustee in personal liability.

SECTION 6.06.    LIMITATION ON SUITS.

         A Holder of a Debenture may pursue a remedy with respect to this
Indenture or the Debentures only if:

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

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

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

          (d)    the Trustee does not comply with the request within 60 days
after receipt of the request and the offer and, if requested, the provision of
indemnity; and

          (e)    during such 60-day period the Holders of a majority in
principal amount at maturity of the then outstanding Debentures do not give the
Trustee a direction inconsistent with the request.

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

SECTION 6.07.    RIGHTS OF HOLDERS OF DEBENTURES TO RECEIVE PAYMENT.

         Notwithstanding any other provision of this Indenture, the right of
any Holder of a Debenture to receive payment of principal, premium and
Liquidated Damages, if any, and interest on the Debenture, on or after the
respective due dates expressed in the Debenture (including in connection with
an offer to purchase), or to bring suit for the enforcement of any such payment
on or after such respective dates, shall not be impaired or affected without
the consent of such Holder.

SECTION 6.08.    COLLECTION SUIT BY TRUSTEE.

         If an Event of Default specified in Section 6.01(a) or (b) occurs and
is continuing, the Trustee is authorized to recover judgment in its own name
and as trustee of an express trust against the Issuer for the whole amount of
principal of, premium and Liquidated Damages, if any, and interest remaining
unpaid on the Debentures and interest on overdue principal and, to the extent
lawful, interest and such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09.    TRUSTEE MAY FILE PROOFS OF CLAIM.

         The Trustee is authorized to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel)
and the Holders of the Debentures allowed in any judicial proceedings relative
to the Issuer (or any other obligor upon the Debentures), its creditors or its
property and shall be entitled and empowered to collect, receive and distribute
any money or other property payable or deliverable on any such claims and any
custodian in any such judicial proceeding is hereby authorized by





                                       47
<PAGE>   55
each Holder to make such payments to the Trustee, and in the event that the
Trustee shall consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 7.07 hereof.  To the extent
that the payment of any such compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel, and any other amounts due the Trustee
under Section 7.07 hereof out of the estate in any such proceeding, shall be
denied for any reason, payment of the same shall be secured by a Lien on, and
shall be paid out of, any and all distributions, dividends, money, securities
and other properties that the Holders may be entitled to receive in such
proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise.  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 Debentures or the rights of any Holder, 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, it shall
pay out the money in the following order:

         First:  to the Trustee, its agents and attorneys for amounts due under
Section 7.07 hereof, including payment of all compensation, expenses and
liabilities incurred, and all advances made, by the Trustee and the costs and
expenses of collection;

         Second:  to Holders of Debentures for amounts due and unpaid on the
Debentures for principal, premium and Liquidated Damages, if any, and interest,
ratably, without preference or priority of any kind, according to the amounts
due and payable on the Debentures for principal, premium and Liquidated
Damages, if any and interest, respectively; and

         Third: to the Issuer or to such party as a court of competent
jurisdiction shall direct.

         The Trustee may fix a record date and payment date for any payment to
Holders of Debentures 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 a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Trustee, a suit by a Holder of a
Debenture pursuant to Section 6.07 hereof, or a suit by Holders of more than
10% in principal amount at maturity of the then outstanding Debentures.

SECTION 7.01.    DUTIES OF TRUSTEE.

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

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





                                       48
<PAGE>   56
                 (i)      the duties and obligations of the Trustee shall be
             determined solely by the express provisions of this Indenture and
             the Trustee need perform only those duties and obligations that
             are specifically set forth in this Indenture and no others, and no
             implied covenants or obligations shall be read into this Indenture
             against the Trustee; and

                 (ii)     in the absence of bad faith on its part, the Trustee
             may conclusively rely, as to the truth of the statements and the
             correctness of the opinions expressed therein, upon any
             statements, certificates or opinions furnished to the Trustee and
             conforming to the requirements of this Indenture.  However, the
             Trustee shall examine the statements, certificates and opinions to
             determine whether or not they conform to the requirements of this
             Indenture.

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

                 (i)      this paragraph does not limit the effect of paragraph
             (b) of this Section;

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

                 (iii)    the Trustee shall not be liable with respect to any
             action it takes or omits to take in good faith in accordance with
             a direction received by it pursuant to Section 6.05 hereof.

          (d)    Whether or not therein expressly so provided, every provision
of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b), and (c) of this Section.

          (e)    No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any liability.  The Trustee
shall be under no obligation to exercise any of its rights and powers under
this Indenture at the request of any Holders, unless such Holder shall have
offered to the Trustee security and indemnity satisfactory to it against any
loss, liability or expense.

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

SECTION 7.02.    RIGHTS OF TRUSTEE.

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

          (b)    Any request, direction, order or demand of the Issuer for the
Trustee to act or refrain from acting shall be sufficiently evidenced by an
Officers' Certificate (unless other evidence in respect thereof be herein
specifically prescribed) or an Opinion of Counsel or both.  The Trustee shall
not be liable for any action it takes or omits to take in good faith in
reliance on such Officers' Certificate or Opinion of Counsel.   Any resolution
of the Board of Directors shall be evidenced to the Trustee by a copy thereof,
which, if requested by the Trustee, shall be certified by the secretary or any
assistant secretary of the Issuer.  The Trustee may consult with counsel and
the written advice of such counsel or any Opinion of Counsel shall be full and
complete authorization and protection from liability in respect of any action
taken, suffered or omitted by it hereunder in good faith and in reliance
thereon.

          (c)    The Trustee may act through its attorneys and agents
(including those not regularly in its employ) and shall not be responsible for
the misconduct or negligence of any agent appointed with due care.

<PAGE>   57
          (d)    The Trustee shall not be liable for any action it takes or
omits to take in good faith that it believes to be authorized or within the
rights or powers conferred upon it by this Indenture.

          (e)    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 unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
that 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 Debentures and may otherwise deal with the Issuer or any
Affiliate of the Issuer with the same rights it would have if it were not
Trustee.  However, in the event that the Trustee acquires any conflicting
interest it must eliminate such conflict within 90 days, apply to the
Commission for permission to continue as trustee or resign.  Any Agent may do
the same with like rights and duties.  The Trustee is also subject to Sections
7.10 and 7.11 hereof.

SECTION 7.04.    TRUSTEE'S DISCLAIMER.

         The Trustee assumes no responsibility for the correctness of,  and
makes no representation as to the validity or adequacy of, this Indenture or
the Debentures, it shall not be accountable for the Issuer's use of the
proceeds from the Debentures or any money paid to the Issuer or upon the
Issuer's direction under any provision of this Indenture, it shall not be
responsible for the use or application of any money received by any Paying
Agent other than the Trustee, and it shall not be responsible for any statement
or recital herein or any statement in the Debentures or any other document in
connection with the sale of the Debentures or pursuant to this Indenture other
than its certificate of authentication.  The Trustee shall not be accountable
for any calculations made in respect hereof.

SECTION 7.05.    NOTICE OF DEFAULTS.

         If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to Holders of Debentures a notice
of the Default or Event of Default within 90 days after it occurs.  Except in
the case of a Default or Event of Default in payment of principal of, premium,
if any, or interest or Liquidated Damages, if any, on any Debenture, the
Trustee may withhold the notice if and so long as a committee of its board of
directors, executive committee or a trust committee of directors or Responsible
Officers in good faith determines that withholding the notice is in the
interests of the Holders of the Debentures.

SECTION 7.06.    REPORTS BY TRUSTEE TO HOLDERS OF THE DEBENTURES.

         Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, and for so long as Debentures remain outstanding,
the Trustee shall mail to the Holders of the Debentures a brief report dated as
of such reporting date that complies with TIA Section 313(a) (but if no event
described in TIA Section 313(a) has occurred within the twelve months
preceding the reporting date, no report need be transmitted).  The Trustee also
shall comply with TIA Section 313(b)(2).  The Trustee shall also transmit by
mail all reports as required by TIA Section 313(c).

         A copy of each report at the time of its mailing to the Holders of
Debentures shall be mailed to the Issuer and filed with the Commission and each
stock exchange on which the Debentures are listed in accordance with TIA
Section 313(d).  The Issuer shall promptly notify the Trustee when the
Debentures are listed on any stock exchange.

SECTION 7.07.    COMPENSATION AND INDEMNITY.

         The Issuer shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder.  The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust.  The Issuer shall reimburse the Trustee promptly
upon request for all reasonable disbursements, advances and expenses incurred
or made by or on behalf of it in addition to the compensation for its





                                       50
<PAGE>   58
services.  Such expenses shall include, without limitation, the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

         The Issuer shall indemnify and hold harmless the Trustee against any
and all losses, liabilities or expenses incurred by it arising out of or in
connection with the acceptance or administration of its duties under this
Indenture, including, without limitation, the costs and expenses of enforcing
this Indenture against the Issuer (including this Section 7.07) and defending
itself against any claim (whether asserted by the Issuer or any Holder or any
other person) or liability in connection with the exercise or performance of
any of its powers or duties hereunder, except to the extent any such loss,
liability or expense may be attributable to its negligence or bad faith.  The
Trustee shall notify the Issuer promptly of any claim for which it may seek
indemnity.  Failure by the Trustee to so notify the Issuer shall not relieve
the Issuer of its obligations hereunder.  The Issuer shall defend the claim and
the Trustee shall cooperate in the defense.  The Trustee may have separate
counsel and the Issuer shall pay the reasonable fees and expenses of such
counsel.  The Issuer need not pay for any settlement made without its consent,
which consent shall not be unreasonably withheld.

         The obligations of the Issuer under this Section 7.07 shall constitute
additional indebtedness hereunder and shall survive the satisfaction and
discharge of this Indenture.

         To secure the Issuer's payment obligations in this Section, the
Trustee shall have a Lien prior to the Debentures on all money or property held
or collected by the Trustee, except for that money or property held in trust to
pay principal and interest and Liquidated Damages, if any, on particular
Debentures.  Such Lien shall survive the satisfaction and discharge of this
Indenture.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(g) or (h) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents
and counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

         The Trustee shall comply with the provisions of TIA Section 313(b)(2)
to the extent applicable.

SECTION 7.08.    REPLACEMENT OF TRUSTEE.

         A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

         The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Issuer.  The Holders of Debentures
of a majority in principal amount at maturity of the then outstanding
Debentures may remove the Trustee by so notifying the Trustee and the Issuer in
writing.  The Issuer may remove the Trustee if:

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

          (b)    the Trustee is adjudged a bankrupt or an insolvent or an order
for relief is entered with respect to the Trustee under any Bankruptcy Law;

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

          (d)    the Trustee becomes incapable of acting.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Issuer shall promptly appoint a successor
Trustee.  Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount at maturity of the then outstanding
Debentures may appoint a successor Trustee to replace the successor Trustee
appointed by the Issuer.





                                       51
<PAGE>   59
         If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Issuer, or
the Holders of Debentures of at least 10% in principal amount at maturity of
the then outstanding Debentures may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

         If the Trustee, after written request by any Holder of a Debenture who
has been a Holder of a Debenture for at least six months, fails to comply with
Section 7.10, such Holder of a Debenture may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuer.  Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture.  The successor Trustee shall mail a notice of its
succession to Holders of the Debentures.  The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, provided
that all sums owing to the Trustee hereunder have been paid and subject to the
Lien provided for in Section 7.07 hereof.  Notwithstanding replacement of the
Trustee pursuant to this Section 7.08, the Issuer's obligations under Section
7.07 hereof shall continue for the benefit of the retiring Trustee.

SECTION 7.09.    SUCCESSOR TRUSTEE BY MERGER, ETC.

         If the Trustee consolidates, merges or converts into, or transfers all
or substantially all of its corporate trust business to, another corporation,
the successor corporation without any further act shall be the successor
Trustee.

SECTION 7.10.    ELIGIBILITY; DISQUALIFICATION.

         There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or
state authorities and that has a combined capital and surplus of at least $100
million as set forth in its most recent published annual report of condition.

         This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1), (2) and (5).  The Trustee is subject to
TIA Section 310(b).

SECTION 7.11.    PREFERENTIAL COLLECTION OF CLAIMS AGAINST ISSUER.

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



                                   ARTICLE 8.

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE



SECTION 8.01.    OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

         The Issuer may, at the option of its Board of Directors evidenced by a
resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Debentures
upon compliance with the conditions set forth below in this Article Eight.

SECTION 8.02.    LEGAL DEFEASANCE AND DISCHARGE.

         Upon the Issuer's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Issuer shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be deemed to have been





                                       52
<PAGE>   60
discharged from its obligations with respect to all outstanding Debentures on
the date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance").  For this purpose, Legal Defeasance means that the Issuer shall
be deemed to have paid and discharged the entire Indebtedness represented by
the outstanding Debentures, which shall thereafter be deemed to be
"outstanding" only for the purposes of Section 8.05 hereof and the other
Sections of this Indenture referred to in (a) and (b) below, and to have
satisfied all its other obligations under such Debentures and this Indenture
(and the Trustee, on demand of and at the expense of the Issuer, shall execute
proper instruments acknowledging the same), except for the following provisions
which shall survive until otherwise terminated or discharged hereunder:

          (a)    the rights of Holders of outstanding Debentures to receive
payments in respect of the principal of, premium, if any, and interest and
Liquidated Damages, if any, on such Debentures when such payments are due from
the trust referred to below,

          (b)    the Issuer's obligations with respect to the Debentures
concerning issuing temporary Debentures, registration of Debentures, mutilated,
destroyed, lost or stolen Debentures and the maintenance of an office or agency
for payment and money for security payments held in trust,

          (c)    the rights, powers, trusts, duties and immunities of the
Trustee, and the Issuer's obligations in connection therewith and

          (d)    the Legal Defeasance provisions of this Indenture.

SECTION 8.03.    COVENANT DEFEASANCE.

         Upon the Issuer's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Issuer shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from its
obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10,
4.11, 4.12, 4.13, 4.14, 4.15, 4.16 and 4.17 hereof with respect to the
outstanding Debentures on and after the date the conditions set forth in
Section 8.04 are satisfied (hereinafter, "Covenant Defeasance"), and the
Debentures shall thereafter be deemed not "outstanding" for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Debentures shall not be deemed outstanding for accounting
purposes).  For this purpose, Covenant Defeasance means that, with respect to
the outstanding Debentures, the Issuer may omit to comply with and shall have
no liability in respect of any term, condition or limitation set forth in any
such covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such covenant or by reason of any reference in any such
covenant to any other provision herein or in any other document and such
omission to comply shall not constitute a Default or an Event of Default under
Section 6.01 hereof, but, except as specified above, the remainder of this
Indenture and such Debentures shall be unaffected thereby.  In addition, upon
the Issuer's exercise under Section 8.01 hereof of the option applicable to
this Section 8.03 hereof, subject to the satisfaction of the conditions set
forth in Section 8.04 hereof, Sections 6.01(d) through 6.01(f) hereof shall not
constitute Events of Default.

SECTION 8.04.    CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

         The following shall be the conditions to the application of either
Section 8.02 or 8.03 hereof to the outstanding Debentures:

          In order to exercise either Legal Defeasance or Covenant Defeasance,

          (a)    the Issuer must irrevocably deposit with the Trustee, in
trust, for the benefit of the Holders of the Debentures, cash in U.S. dollars,
non-callable Government Securities, or a combination thereof, in such amounts
as will be sufficient, in the opinion of a nationally recognized firm of
independent public accountants, to pay the principal of, premium, if any, and
interest and Liquidated Damages, if any, on the outstanding Debentures on the
stated maturity or





                                       53
<PAGE>   61
on the applicable redemption date, as the case may be, and the Issuer must
specify whether the Debentures are being defeased to maturity or to a
particular redemption date,

          (b)    in the case of Legal Defeasance, the Issuer shall have
delivered to the Trustee an Opinion of Counsel in the United States reasonably
acceptable to the Trustee confirming that (i) the Issuer has received from, or
there has been published by, the Internal Revenue Service a ruling or (ii)
since the date of this Indenture, there has been a change in the applicable
federal income tax law, in either case to the effect that, and based thereon
such opinion of counsel shall confirm that, subject to customary assumptions
and exclusions, the Holders of the outstanding Debentures will not recognize
income, gain or loss for federal income tax purposes as a result of such Legal
Defeasance and will be subject to federal income tax on the same amounts, in
the same manner and at the same times as would have been the case if such Legal
Defeasance had not occurred,

          (c)    in the case of Covenant Defeasance, the Issuer shall have
delivered to the Trustee an Opinion of Counsel in the United States reasonably
acceptable to the Trustee confirming that, subject to customary assumptions and
exclusions, the Holders of the outstanding Debentures will not recognize
income, gain or loss for federal income tax purposes as a result of such
Covenant Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case
if such Covenant Defeasance had not occurred,

          (d)    no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of
Default resulting from the borrowing of funds to be applied to such deposit)
or, insofar as Events of Default from bankruptcy or insolvency events are
concerned, at any time in the period ending on the 123rd day after the date of
deposit,

          (e)    such Legal Defeasance or Covenant Defeasance will not result
in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than this Indenture) to which the Issuer or any
of its Subsidiaries is a party or by which the Issuer or any of its
Subsidiaries is bound,

          (f)    the Issuer must have delivered to the Trustee an Opinion of
Counsel reasonably acceptable to the Trustee confirming that, subject to
customary assumptions and exclusions, after the 123rd day following the
deposit, the trust funds will not be subject to the effect of Section 547 of
the United States Bankruptcy Code or any analogous New York State law provision
or any other applicable federal or New York bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally,

          (g)    the Issuer must deliver to the Trustee an Officers'
Certificate stating that the deposit was not made by the Issuer with the intent
of preferring the Holders of Debentures over the other creditors of the Issuer
with the intent of defeating, hindering, delaying or defrauding creditors of
the Issuer or others, and

          (h)    the Issuer must deliver to the Trustee an Officers'
Certificate and an Opinion of Counsel (which opinion may be subject to
customary assumptions and exclusions) reasonably acceptable to the Trustee
confirming that all conditions precedent provided for relating to the Legal
Defeasance or the Covenant Defeasance have been complied with.

SECTION 8.05.    DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN TRUST;
OTHER MISCELLANEOUS PROVISIONS.

         Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding
Debentures shall be held in trust and applied by the Trustee, in accordance
with the provisions of such Debentures and this Indenture, to the payment,
either directly or through any Paying Agent (including the Issuer acting as
Paying Agent) as the Trustee may determine, to the Holders of such Debentures
of all sums due and to become due thereon in respect of principal, premium, if
any, and interest and Liquidated Damages, if any, but such money need not be
segregated from other funds except to the extent required by law.





                                       54
<PAGE>   62
         The Issuer shall pay and indemnify the Trustee against any and all
taxes, fees or other charges imposed on or assessed against the cash or
non-callable Government Securities deposited pursuant to Section 8.04 hereof or
the principal and interest received in respect thereof other than any such
taxes, fees or other charges which by law are for the account of the Holders of
the outstanding Debentures.

         Anything in this Article Eight to the contrary notwithstanding, the
Trustee shall deliver or pay to the Issuer from time to time upon the request
of the Issuer any money or non-callable Government Securities held by it as
provided in Section 8.04 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee (which may be the opinion
delivered under Section 8.04(a) hereof), are in excess of the amount thereof
that would then be required to be deposited to effect an equivalent Legal
Defeasance or Covenant Defeasance.

SECTION 8.06.    REPAYMENT TO ISSUER.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Issuer, in trust for the payment of the principal of, premium, if any,
or interest or Liquidated Damages, if any, on any Debenture and remaining
unclaimed for two years after such principal, and premium, if any, or interest
or Liquidated Damages, if any, has become due and payable shall be paid to the
Issuer on its request or (if then held by the Issuer) shall be discharged from
such trust; and the Holder of such Debenture shall thereafter, as a secured
creditor, look only to the Issuer for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all
liability of the Issuer as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make
any such repayment, may at the expense of the Issuer cause to be published
once, in the New York Times and The Wall Street Journal (national edition),
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Issuer.

SECTION 8.07.    REINSTATEMENT.

         If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02
or 8.03 hereof, as the case may be, by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Issuer's obligations under this Indenture and the
Debentures shall be revived and reinstated as though no deposit had occurred
pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or
Paying Agent is permitted to apply all such money in accordance with Section
8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Issuer
makes any payment of principal of, premium, if any, or interest or Liquidated
Damages, if any, on any Debenture following the reinstatement of its
obligations, the Issuer shall be subrogated to the rights of the Holders of
such Debentures to receive such payment from the money held by the Trustee or
Paying Agent.

                                   ARTICLE 9.
                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01.    WITHOUT CONSENT OF HOLDERS OF DEBENTURES.

         Notwithstanding Section 9.02 of this Indenture, the Issuer and the
Trustee may amend or supplement this Indenture or the Debentures without the
consent of any Holder of a Debenture:

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

          (b)    to provide for uncertificated Debentures in addition to or in
place of certificated Debentures or to alter the provisions of Article 2 hereof
(including the related definitions) in a manner that does not materially
adversely affect any Holder;

          (c)    to provide for the assumption of the Issuer's obligations to
the Holders of the Debentures by a successor to the Issuer pursuant to Article
5 hereof;





                                       55
<PAGE>   63
          (d)    to make any change that would provide any additional rights or
benefits to the Holders of the Debentures or that does not adversely affect the
legal rights hereunder of any Holder of the Debenture;

          (e)    to comply with requirements of the Commission in order to
effect or maintain the qualification of this Indenture under the TIA; or

          (f)    to provide for the issuance of Additional Debentures in
accordance with the limitations set forth in this Indenture as of the date
hereof.

         Upon the request of the Issuer accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon receipt by the Trustee an Officer's
Certificate and an Opinion of Counsel (both reasonably acceptable to the
Trustee) as conclusive evidence that any such supplemental indenture complies
with the applicable provisions of this Indenture, the Trustee shall join with
the Issuer in the execution of any amended or supplemental Indenture authorized
or permitted by the terms of this Indenture and make any further appropriate
agreements and stipulations that may be therein contained, but the Trustee
shall not be obligated to enter into such amended or supplemental Indenture
that affects its own rights, duties or immunities under this Indenture or
otherwise.

SECTION 9.02.    WITH CONSENT OF HOLDERS OF DEBENTURES.

         Except as provided below in this Section 9.02, the Issuer and the
Trustee may amend or supplement this Indenture (including Section 3.09, 4.10
and 4.15 hereof), the Debentures may be amended or supplemented with the
consent of the Holders of at least a majority in principal amount at maturity
of the Debentures (including Additional Debentures, if any) then outstanding
voting as a single class (including consents obtained in connection with a
tender offer or exchange offer for, or purchase of, the Debentures), and,
subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of
Default (other than a Default or Event of Default in the payment of the
principal, premium, if any, or interest or Liquidated Damages, if any, on the
Debentures, except a payment default resulting from an acceleration that has
been rescinded) or compliance with any provision of this Indenture or the
Debentures may be waived with the consent of the Holders of a majority in
principal amount at maturity of the then outstanding Debentures (including
Additional Debentures, if any) voting as a single class (including consents
obtained in connection with a tender offer or exchange offer for, or purchase
of, the Debentures).  Notwithstanding the foregoing, any amendment to or waiver
of Sections 4.10 and 4.14 hereof will require the consent of the Holders of at
least two-thirds in aggregate principal amount at maturity of the Debentures
then outstanding if such amendment would materially adversely affect the rights
of Holders of Debentures.  Section 2.08 hereof shall determine which Debentures
are considered to be "outstanding" for purposes of this Section 9.02.

         Upon the request of the Issuer accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon the filing with the Trustee of evidence
satisfactory to the Trustee of the consent of the Holders of Debentures as
aforesaid, and upon receipt by the Trustee of an Officer's Certificate and an
Opinion of Counsel (both reasonably acceptable to the Trustee) as conclusive
evidence that any such supplemental Indenture complies with the applicable
provisions of this Indenture, the Trustee shall join with the Issuer in the
execution of such amended or supplemental Indenture unless such amended or
supplemental Indenture directly affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise, in which case the Trustee may in
its discretion, but shall not be obligated to, enter into such amended or
supplemental Indenture.

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

         After an amendment, supplement or waiver under this Section becomes
effective, the Issuer shall mail to the Holders of Debentures affected thereby
a notice briefly describing the amendment, supplement or waiver.  Any failure
of the Issuer to mail such notice, or any defect therein, shall not, however,
in any way impair or affect the validity of any such amended or supplemental
Indenture or waiver.  Subject to Sections 6.04 and 6.07 hereof, the





                                       56

Holders of a majority in aggregate principal amount at maturity of the
Debentures (including Additional Debentures, if any) then outstanding voting as
a single class may waive compliance in a particular instance by the Issuer with
any provision of this Indenture or the Debentures.  However, without the
consent of each Holder affected, an amendment or waiver under this Section 9.02
may not (with respect to any Debentures held by a non-consenting Holder):

          (a)    reduce the principal amount at maturity of Debentures whose
Holders must consent to an amendment, supplement or waiver,

          (b)    reduce the principal of or change the fixed maturity of any
Debenture or alter the provisions with respect to the redemption of the
Debentures (other than Sections 4.10 and 4.14 hereof) or amend or modify the
calculation of the Accreted Value so as to reduce the amount of the Accreted
Value of the Debentures,

          (c)    reduce the rate of or change the time for payment of interest
on any Debentures,

          (d)    waive a Default or Event of Default in the payment of
principal of or premium, if any, or interest or Liquidated Damages, if any, on
the Debentures (except a rescission of acceleration of the Debentures by the
Holders of at least a majority in aggregate principal amount at maturity of the
Debentures and a waiver of the payment default that resulted from such
acceleration),

          (e)    make any Debentures payable in money other than that stated in
the Debentures,

          (f)    make any change in the provisions of this Indenture relating
to waivers of past Defaults,

          (g)    waive a redemption payment with respect to any Debentures
(other than Sections 4.10 and 4.14 hereof),

          (h)    make any change in the foregoing amendment and waiver
provisions,

          (i)    modify any provision of this Indenture with respect to the
priority of the Debentures in right of payment, or

          (j)    make any change to the right of Holders to waive an existing
Default or Event of Default or the right of Holders to receive payments of
principal, premium, if any, and interest and Liquidated Damages, if any, on the
Debentures.

SECTION 9.03.    COMPLIANCE WITH TRUST INDENTURE ACT.

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

SECTION 9.04.    REVOCATION AND EFFECT OF CONSENTS.

         Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Debenture is a continuing consent by the Holder of a
Debenture and every subsequent Holder of a Debenture or portion of a Debenture
that evidences the same debt as the consenting Holder's Debenture, even if
notation of the consent is not made on any Debenture.  However, any such Holder
of a Debenture or subsequent Holder of a Debenture may revoke the consent as to
its Debenture if the Trustee receives written notice of revocation before the
date the waiver, supplement or amendment becomes effective.  An amendment,
supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder.

<PAGE>   65
SECTION 9.05.    NOTATION ON OR EXCHANGE OF DEBENTURES.

         The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Debenture thereafter authenticated.  The Issuer in
exchange for all Debentures may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Debentures that reflect the amendment,
supplement or waiver.

         Failure to make the appropriate notation or issue a new Debenture
shall not affect the validity and effect of such amendment, supplement or
waiver.

SECTION 9.06.    TRUSTEE TO SIGN AMENDMENTS, ETC.

         The Trustee shall sign any amended or supplemental Indenture
authorized pursuant to this Article Nine if the amendment or supplement does
not adversely affect the rights, duties, liabilities or immunities of the
Trustee.  The Issuer may not sign an amendment or supplemental Indenture until
the Board of Directors approves it.  In executing any amended or supplemental
indenture, the Trustee shall be entitled to receive and (subject to Section
7.01 hereof) shall be fully protected in relying upon, in addition to the
documents required by Section 10.04 hereof, an Officer's Certificate and an
Opinion of Counsel stating that the execution of such amended or supplemental
indenture is authorized or permitted by this Indenture.

         Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

         1.       INTEREST. Mercury Acquisition Corporation, a Delaware
corporation (the "Issuer"), promises to pay interest on the principal amount at
maturity of this Debenture at 12 1/2% per annum from June 1, 2003 until maturity
and shall pay the Liquidated Damages payable pursuant to Section 5 of the
Registration Rights Agreement referred to below. The Issuer will pay interest
and Liquidated Damages semi-annually on June 1 and December 1 of each year, or
if any such day is not a Business Day, on the next succeeding Business Day
(each, an "Interest Payment Date"). Interest on the Debentures will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from June 1, 2003; provided that if there is no existing Default in the
payment of interest, and if this Debenture is authenticated between a record
date referred to on the face hereof and the next succeeding Interest Payment
Date, interest shall accrue from such next succeeding Interest Payment Date; and
provided further that the first Interest Payment Date shall be December 1, 2003.
The Issuer shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal and premium, if any,
from time to time on demand at a rate that is 1% per annum in excess of the rate
then in effect; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace periods) from time to
time on demand at the same rate to the extent lawful. Interest will be computed
on the basis of a 360-day year of twelve 30-day months.

         2.       METHOD OF PAYMENT. The Issuer will pay interest on the
Debentures (except defaulted interest) and Liquidated Damages to the Persons who
are registered Holders of Debentures at the close of business on the May 15 or
November 15 next preceding the Interest Payment Date, even if such Debentures
are cancelled after such record date and on or before such Interest Payment
Date, except as provided in Section 2.12 of the Indenture with respect to
defaulted interest. The Debentures will be payable as to principal, premium and
Liquidated Damages, if any, and interest at the office of the Paying Agent and
Registrar. Holders of Debentures must surrender their Debentures to the Paying
Agent to collect principal payments, and the Issuer may pay principal and
interest and Liquidated Damages, if any, by check and may mail checks to a
Holder's registered address; provided that all payments with respect to Global
Debentures and Definitive Debentures, the Holders of which have given wire
transfer instructions to the Issuer, will be required to be made by wire
transfer of immediately available funds to the accounts specified by the Holders
thereof. Such payment shall be in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts.

         3.       PAYING AGENT AND REGISTRAR. Initially, IBJ Schroder Bank &
Trust Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Issuer may change any Paying Agent or Registrar without notice to
any Holder. The Issuer or any of its Subsidiaries may act in any such capacity.

         4.       INDENTURE The Issuer issued the Debentures under an Indenture,
dated as of May 22, 1998 ("Indenture"), between the Issuer and the Trustee. The
terms of the Debentures include those



                                     A-1-4
<PAGE>   5

stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb).
The Debentures are subject to all such terms, and Holders are referred to the
Indenture and such Act for a statement of such terms. To the extent any
provision of this Debenture conflicts with the express provisions of the
Indenture, the provisions of the Indenture shall govern and be controlling. The
Debentures are obligations of the Issuer initially limited to $174 million in
aggregate principal amount at maturity.

         5.       OPTIONAL REDEMPTION.

         (a) Except as set forth in subparagraph (b) of this Paragraph 5, the
Debentures will not be redeemable at the Issuer's option prior to June 1, 2003.
Thereafter, the Debentures will be subject to redemption at any time at the
option of the Issuer, in whole or in part, upon not less than 30 nor more than
60 days' notice, in cash at the redemption prices (expressed as percentages of
principal amount at maturity) set forth below, plus accrued and unpaid interest
and Liquidated Damages, if any, thereon to the applicable redemption date, if
redeemed during the twelve-month period beginning on June 1 of the years
indicated below:

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


         (b) Notwithstanding the provisions of subparagraph (a) of this
Paragraph 5, on or prior to June 1, 2001, the Issuer may redeem up to 100% of
the aggregate principal amount at maturity of Debentures ever issued under the
Indenture in cash at a redemption price of 112.50% of the Accreted Value
thereof, plus Liquidated Damages, if any, thereon to the redemption date, with
the net cash proceeds of one or more Public Equity Offerings; provided that, in
the event that the Issuer redeems less than 100% of the then outstanding
Debentures, at least 60% of the aggregate principal amount at maturity of the
Debentures ever issued under the Indenture remains outstanding immediately after
the occurrence of any such redemption; and provided further that such redemption
shall occur within 90 days of the date of the closing of any such Public Equity
Offering.

         (c) In addition, at any time prior to June 1, 2003, the Issuer may, at
its option upon the occurrence of a Change of Control, redeem the Debentures, in
whole but not in part, upon not less than 30 nor more than 60 days' prior notice
(but in no event may any such redemption occur more than 60 days after the
occurrence of such Change of Control), in cash at a redemption price equal to
(i) the present value of the sum of all the remaining premium and principal
payments that would become due on the Debentures as if the Debentures were to
remain outstanding and be redeemed on June 1, 2003, computed using a discount
rate equal to the Treasury Rate plus 50 basis points, plus (ii) Liquidated
Damages, if any, to the date of redemption.

<PAGE>   6

         6.       MANDATORY REDEMPTION.

         Except as set forth in paragraph 7 below, the Issuer is not required to
make mandatory redemption of, or sinking fund payments with respect to, the
Debentures.

         7.       REPURCHASE AT OPTION OF HOLDER.

         (a) Upon the occurrence of a Change of Control, each Holder of
Debentures shall have the right to require the Issuer to purchase all or any
part (equal to $1,000 or an integral multiple thereof) of such Holder's
Debentures pursuant to an offer at an offer price in cash equal to 101% of the
aggregate principal amount at maturity thereof, plus any accrued and unpaid
interest and Liquidated Damages, if any, thereon to the date of repurchase (or,
in the case of repurchases of Debentures prior to June 1, 2003, at a purchase
price equal to 101% of the Accreted Value thereof plus Liquidated Damages, if
any, thereon as of the date of redemption). Within 65 days following any Change
of Control, subject to the provisions of the Indenture, the Issuer shall mail a
notice to each Holder of Debentures at such Holder's registered address setting
forth the procedures governing the offer as required by the Indenture.

         (b) When the aggregate amount of Excess Proceeds exceeds $15.0 million,
the Issuer will be required to make and offer to all Holders of Debentures (an
"Asset Sale Offer") to purchase the maximum principal amount at maturity of
Debentures that may be purchased out of Excess Proceeds, at an offer price in
cash in an amount equal to 100% of the principal amount at maturity thereof,
plus accrued and unpaid interest and Liquidated Damages, if any, thereon to the
date of purchase (or, in the case of repurchases of Debentures prior to June 1,
2003, at a purchase price equal to 100% of the Accreted Value thereof, plus
Liquidated Damages, if any, thereon as of the date of repurchase), in accordance
with the procedures set forth in the Indenture. Holders of Debentures that are
subject to an offer to purchase will receive an Asset Sale Offer from the Issuer
prior to any related purchase date and may elect to have such Debentures
purchased by completing the form entitled "Option of Holder to Elect Purchase"
on the reverse side of this Debenture.

         8.       NOTICE OF REDEMPTION. Notice of any redemption or offer to
purchase will be mailed at least 30 days but not more than 60 days before the
redemption or purchase date to each Holder of Debentures to be redeemed or
purchased at such Holder's registered address. Debentures in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of
$1,000, unless all of the Debentures held by a Holder are to be redeemed. On and
after the redemption date interest and Liquidated Damages, if any, will cease to
accrue on Debentures or portions thereof called for redemption.

         9.       DENOMINATIONS, TRANSFER, EXCHANGE. The Debentures are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Debentures may be registered and Debentures
may be exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Issuer may require a Holder to pay any taxes and fees
required by law or permitted by the Indenture. The Issuer need not exchange or
register the transfer of any Debenture or portion of a Debenture selected for
redemption, except for the unredeemed portion of any Debenture being redeemed in
part. Also, the Issuer need not exchange or register the transfer of any
Debentures for a period of 15 days before a selection of Debentures to be
redeemed or during the period between a record date and the corresponding
Interest Payment Date.

<PAGE>   7

         10.      PERSONS DEEMED OWNERS. The registered Holder of a Debenture
may be treated as its owner for all purposes.

         11.      AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
exceptions set forth in the Indenture, the Indenture and the Debentures may be
amended or supplemented with the consent of the Holders of at least a majority
in principal amount at maturity of the Debentures then outstanding (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, Debentures), and any existing default or
compliance with any provision of the Indenture or the Debentures may be waived
with the consent of the Holders of a majority in principal amount at maturity of
the then outstanding Debentures (including, without limitation, consents
obtained in connection with a purchase of, or tender offer or exchange offer
for, Debentures). Notwithstanding the foregoing, without the consent of any
Holder of Debentures, the Issuer and the Trustee may amend or supplement the
Indenture or the Debentures to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Debentures in addition to or in place of certificated
Debentures, to provide for the assumption of the Issuer's obligations to Holders
of Debentures in the case of a merger or consolidation or sale of all or
substantially all of the Issuer's assets, to make any change that would provide
any additional rights or benefits to the Holders of Debentures or that does not
materially adversely affect the legal rights under the Indenture of any such
Holder, or to comply with requirements of the Commission in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act or to
provide for guarantees of the Debentures.

         12.      DEFAULTS AND REMEDIES.

         (a) Events of Default include: (a) default for 30 days in the payment
when due of interest on, or Liquidated Damages with respect to, the Debentures;
(b) default in payment when due of the principal of or premium, if any, on the
Debentures at maturity, upon redemption or otherwise; (c) failure by the Issuer
or any of its Restricted Subsidiaries for 30 days after receipt of notice from
the Trustee or Holders of at least 25% in principal amount at maturity of the
Debentures then outstanding to comply with the provisions of Sections 4.07,
4.09, 4.10, 4.15 and 5.01 of the Indenture; (d) failure by the Issuer for 60
days after notice from the Trustee or the Holders of at least 25% in principal
amount at maturity of the Debentures then outstanding to comply with any of its
other agreements in the Indenture or the Debentures; (e) default under any
mortgage, indenture or instrument under which there may be issued or by which
there may be secured or evidenced any Indebtedness for money borrowed by the
Issuer or any of its Restricted Subsidiaries (or the payment of which is
guaranteed by the Issuer or any of its Restricted Subsidiaries), whether such
Indebtedness or guarantee now exists, or is created after the date of the
Indenture, which default (i) is caused by a failure to pay Indebtedness at its
stated final maturity (after giving effect to any applicable grace period
provided in such Indebtedness) (a "Payment Default") or (ii) results in the
acceleration of such Indebtedness prior to its stated final maturity and, in
each case, the principal amount of any such Indebtedness, together with the
principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates
$10.0 million or more; (f) failure by the Issuer or any of its Restricted
Subsidiaries to pay final judgments aggregating in excess of $10.0 million (net
of any amounts with respect to which a reputable and creditworthy insurance
company has acknowledged liability in writing), which judgments are not paid,
discharged or stayed for a period of 60 days; and (g) certain events of
bankruptcy or insolvency with respect to the Issuer or any of its Restricted
Subsidiaries that is a Significant Subsidiary. If any Event of Default occurs
and is continuing, the Trustee or the Holders of at least 25% in principal
amount at maturity of the then outstanding Debentures may declare all the
Debentures to be due and payable immediately; provided that, so long as any
Indebtedness permitted to be incurred pursuant to the New Credit Facility shall
be outstanding, such acceleration shall not be effective until the earlier of
(a) an acceleration of any such Indebtedness under the New Credit Facility or
(b) five business days after receipt by the Issuer and the administrative agent
under the New Credit Facility



                                     A-1-7
<PAGE>   8

of written notice of such acceleration. Notwithstanding the foregoing, in the
case of an Event of Default arising from certain events of bankruptcy or
insolvency with respect to the Issuer or any of its Restricted Subsidiaries that
is a Significant Subsidiary, all outstanding Debentures will become due and
payable without further action or notice.

         (b) In the event of a declaration of acceleration of the Debentures
because an Event of Default has occurred and is continuing as a result of the
acceleration of any Indebtedness described in clause (e) of the preceding
paragraph, the declaration of acceleration of the Debentures shall be
automatically annulled if the holders of any Indebtedness described in clause
(e) have rescinded the declaration of acceleration in respect of such
Indebtedness within 30 days of the date of such declaration and if (i) the
annulment of the acceleration of the Debentures would not conflict with any
judgment or decree of a court of competent jurisdiction and (ii) all existing
Events of Default, except non-payment of principal or interest on the Debentures
that became due solely because of the acceleration of the Debentures, have been
cured or waived.

         15.      ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL DEBENTURES.
In addition to the rights provided to Holders of Debentures under the Indenture,
Holders of Restricted Global Debentures shall have the rights set forth in the
Registration Rights Agreement, dated as of May 22, 1998, among the Issuer and
the parties named on the signature pages thereof (the "Registration Rights
Agreement").

         16.      TRUSTEE DEALINGS WITH ISSUER. The Trustee, in its individual
or any other capacity, may make loans to, accept deposits from, and perform
services for the Issuer or its Affiliates, and may otherwise deal with the
Issuer or its Affiliates, as if it were not the Trustee.

         17.      NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder, of the Issuer, as such, shall not have any
liability for any obligations of the Issuer under the Debentures or the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Debenture waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Debentures.

         18.      AUTHENTICATION. This Debenture shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

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

         20.      CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Issuer has caused
CUSIP numbers to be printed on the Debentures and the Trustee may use CUSIP
numbers in notices of redemption as a convenience to Holders. No representation
is made as to the accuracy of such numbers either as printed on the Debentures
or as contained in any notice of redemption and reliance may be placed only on
the other identification numbers placed thereon.

         This Registration Rights Agreement (this "Agreement") is made and
entered into as of May 22, 1998, by and among Mercury Acquisition Corporation, a
Delaware corporation (the "Issuer"), and Donaldson, Lufkin & Jenrette Securities
Corporation (the "Initial Purchaser"), which has agreed to purchase the Issuer's
12-1/2% Senior Discount Debentures due 2008 (the "Series A Debentures") pursuant
to the Purchase Agreement (as defined).

         The Series A Debentures are being issued and sold in connection with
the merger (the "Merger") of the Issuer with and into Thermadyne Holdings
Corporation, a Delaware corporation ("Thermadyne Holdings"), pursuant to an
Agreement and Plan of Merger (the "Merger Agreement"), dated as of January 20,
1998. Upon consummation of the Merger, Thermadyne Holdings will assume all
obligations and liabilities of the Issuer, including the obligations and
liabilities of the Issuer under this Agreement, the Indenture (as defined), the
Series A Debentures and the Purchase Agreement (as defined). All references to
the Issuer in this Agreement refer to the surviving entity in the Merger.

         This Agreement is made pursuant to the Purchase Agreement, dated May
15, 1998 (the "Purchase Agreement"), by and between the Issuer and the Initial

Debentures, the Issuer has agreed to provide the registration rights set forth
in this Agreement. The execution and delivery of this Agreement is a condition

Distribution" contemplated by the Exchange Offer Registration Statement
(including the delivery of the Prospectus contained therein).

SECTION 2. HOLDERS

         A Person is deemed to be a holder of Transfer Restricted Securities
(each, a "Holder") whenever such Person is the holder of record of Transfer
Restricted Securities.

SECTION 3. REGISTERED EXCHANGE OFFER

         (a)     Unless the Exchange Offer shall not be permitted by applicable
federal law (after the procedures set forth in Section 6(a)(i) hereof have been
complied with), the Issuer shall use its reasonable best efforts to (i) cause
the Exchange Offer Registration Statement to be filed with the Commission as
soon as practicable after the Closing Date, but in no event later than 90 days
after the Closing Date (such 90th day, the "Filing Deadline"), (ii) cause such
Exchange Offer Registration Statement to become effective at the earliest
possible time, but in no event later than 180 days after the Closing Date (such
180th day, the "Effectiveness Deadline"), (iii) in connection with the
foregoing, (A) file all pre-effective amendments to such Exchange Offer
Registration Statement as may be necessary in order to cause it to become
effective, and (B) subject to the proviso in Section 6(c)(xii) hereof, cause all
necessary filings, if any, in connection with the registration and qualification
of the Series B Debentures to be made under the Blue Sky laws of such
jurisdictions as are necessary to permit Consummation of the Exchange Offer, and
(iv) upon the effectiveness of such Exchange Offer Registration Statement,
commence and, within the time periods contemplated by Section 3(b) hereof,
Consummate the Exchange Offer. The Exchange Offer shall be on the appropriate
form permitting (i) registration of the Series B Debentures to be offered in
exchange for the Series A Debentures that are Transfer Restricted Securities and
(ii) resales of Series B Debentures by Broker-Dealers that tendered into the
Exchange Offer Series A Debentures that such Broker-Dealer acquired for its own
account as a result of market-making activities or other trading activities
(other than Series A Debentures acquired directly from the Issuer or any of its
Affiliates) as contemplated by Section 3(c) hereof.

         (b)     The Issuer shall use its reasonable best efforts to cause the
Exchange Offer Registration Statement to be effective continuously, and shall
keep the Exchange Offer open for a period of not less than the minimum period
required under applicable federal and state securities laws to Consummate the
Exchange Offer; provided that in no event shall such period be less than 20
Business Days. The Issuer shall cause the Exchange Offer to comply with all
applicable federal and state securities laws. No securities other than the
Series B Debentures shall be included in the Exchange Offer Registration
Statement. The 




                                       3
<PAGE>   5

Issuer shall use its reasonable best efforts to cause the Exchange Offer to be
Consummated on the earliest practicable date after the Exchange Offer
Registration Statement has become effective, but in no event later than 30
Business Days thereafter (such 30th day, the "Consummation Deadline").

         (c)     The Issuer shall include a "Plan of Distribution" section in
the Prospectus contained in the Exchange Offer Registration Statement and
indicate therein that any Broker-Dealer who holds Transfer Restricted Securities
that were acquired for the account of such Broker-Dealer as a result of
market-making activities or other trading activities (other than Series A
Debentures acquired directly from the Issuer or any Affiliate of the Issuer),
may exchange such Transfer Restricted Securities pursuant to the Exchange Offer.
Such "Plan of Distribution" section shall also contain all other information
with respect to such sales by such Broker-Dealers that the Commission may
require in order to permit such sales pursuant thereto, but such "Plan of
Distribution" shall not name any such Broker-Dealer or disclose the amount of
Transfer Restricted Securities held by any such Broker-Dealer, except to the
extent required by the Commission.

         Because such Broker-Dealer may be deemed to be an "underwriter" within
the meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with its initial sale of any Series B
Debentures received by such Broker-Dealer in the Exchange Offer, the Issuer
shall permit the use of the Prospectus contained in the Exchange Offer
Registration Statement by such Broker-Dealer to satisfy such prospectus delivery
requirement for a period of 90 days following the Consummation Date. To the
extent necessary to ensure that the prospectus contained in the Exchange Offer
Registration Statement is available for sales of Series B Debentures by
Broker-Dealers, the Issuer agrees to use its reasonable best efforts to keep the
Exchange Offer Registration Statement continuously effective, supplemented,
amended and current as required by and subject to the provisions of Sections
6(a) and (c) hereof and in conformity with the requirements of this Agreement,
the Act and the policies, rules and regulations of the Commission as announced
from time to time, for a period of 90 days from the Consummation Date or such
shorter period as will terminate when no Transfer Restricted Securities are
outstanding. The Issuer shall provide sufficient copies of the latest version of
such Prospectus to such Broker-Dealers, promptly upon request, at any time
during such period.

SECTION 4. SHELF REGISTRATION

         (a)     Shelf Registration. If (i) the Exchange Offer is not permitted
by applicable law (after the Issuer has complied with the procedures set forth
in Section 6(a)(i) hereof) or (ii) if any Holder of Transfer Restricted
Securities shall notify the Issuer in writing within 20 Business Days following
the Consummation Deadline that (A) based on an opinion of counsel, such Holder
was prohibited by law or Commission policy from participating in the Exchange
Offer or (B) such Holder is a Broker-Dealer and holds Series A Debentures
acquired directly from the Issuer, then the Issuer shall:

                  (x) cause to be filed, on or prior to 90 days after the
         earlier of (i) the date on which the Issuer determines that the
         Exchange Offer Registration Statement cannot be filed as a result of
         Section 4(a)(i) hereof and (ii) the date on which the Issuer receives
         the notice specified in Section 4(a)(ii) hereof (such earlier date, the
         "Filing Deadline"), a shelf registration statement (the "Shelf
         Registration Statement") pursuant to Rule 415 under the Act (which may
         be an amendment to the Exchange Offer Registration Statement) relating
         to (1) all Transfer Restricted Securities in the case of clause (a)(i)
         above or (2) the Transfer Restricted Securities specified in any notice
         in the case of clause (a)(ii) above; and




                                       4
<PAGE>   6

                  (y) shall use its reasonable best efforts to cause such Shelf
         Registration Statement to become effective on or prior to 180 days
         after the Filing Deadline for the Shelf Registration Statement (such
         180th day, the "Effectiveness Deadline").

         If, after the Issuer has filed an Exchange Offer Registration Statement
that satisfies the requirements of Section 3(a) hereof, the Issuer is required
to file and make effective a Shelf Registration Statement solely because the
Exchange Offer is not permitted under applicable federal law (i.e., Section
4(a)(i) hereof), then the filing of the Exchange Offer Registration Statement
shall be deemed to satisfy the requirements of clause (x) above; provided that,
in such event, the Issuer shall remain obligated to meet the Effectiveness
Deadline set forth in clause (y).

         To the extent necessary to ensure that the Shelf Registration Statement
is available for sales of Transfer Restricted Securities by the Holders thereof
entitled to the benefit of this Section 4(a) and the other securities required
to be registered therein pursuant to Section 6(b)(ii) hereof, the Issuer shall
use its reasonable best efforts to keep any Shelf Registration Statement
required by this Section 4(a) continuously effective, supplemented, amended and
current as required by and subject to the provisions of Sections 6(b) and (c)
hereof and in conformity with the requirements of this Agreement, the Act and
the policies, rules and regulations of the Commission as announced from time to
time, until the later of (a) the date on which the Initial Purchaser is no
longer deemed to be an Affiliate of the Issuer, and (b) the earlier of the
second anniversary of the Closing Date (as such date may be extended pursuant to
Section 6(d) hereof) and such earlier date when no Transfer Restricted
Securities covered by such Shelf Registration Statement remain outstanding.

         (b)     Provision by Holders of Certain Information in Connection with
the Shelf Registration Statement. No Holder of Transfer Restricted Securities
may include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Issuer in writing, within 20 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein. No Holder of Transfer
Restricted Securities shall be entitled to liquidated damages pursuant to
Section 5 hereof unless and until such Holder shall have provided all such
information. Each selling Holder agrees to promptly furnish additional
information required to be disclosed in order to make the information previously
furnished to the Issuer by such Holder not materially misleading.

         (c)     Holders of Transfer Restricted Securities that do not give the
written notice within the 20 Business Day period set forth in Section 4(a)
hereof, if required to be given, will no longer have any registration rights
pursuant to this Section 4 and will not be entitled to any Liquidated Damages
pursuant to Section 5 hereof in respect of the Issuer's obligations with respect
to the Shelf Registration Statement.

SECTION 5. LIQUIDATED DAMAGES

         If (i) any Registration Statement required by this Agreement is not
filed with the Commission on or prior to the applicable Filing Deadline, (ii)
any such Registration Statement has not been declared effective by the
Commission on or prior to the applicable Effectiveness Deadline, (iii) the
Exchange Offer has not been Consummated on or prior to the Consummation Deadline
or (iv) any Registration Statement required by this Agreement is filed and
declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose without being succeeded within ten Business Days
by a post-effective amendment to such Registration Statement that cures such
failure and that is itself declared effective ten Business Days 





                                       5
<PAGE>   7

of filing such post-effective amendment to such Registration Statement (each
such event referred to in clauses (i) through (iv), a "Registration Default"),
then the Issuer hereby agrees to pay to each Holder of Transfer Restricted
Securities affected thereby liquidated damages in an amount equal to $.05 per
week per $1,000 in principal amount of Transfer Restricted Securities held by
such Holder for each week or portion thereof that the Registration Default
continues for the first 90-day period immediately following the occurrence of
such Registration Default. The amount of the liquidated damages shall increase
by an additional $.05 per week per $1,000 in principal amount of Transfer
Restricted Securities with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of liquidated
damages of $.25 per week per $1,000 in principal amount of Transfer Restricted
Securities; provided that the Issuer shall in no event be required to pay
liquidated damages for more than one Registration Default at any given time.
Notwithstanding anything to the contrary set forth herein, (1) upon filing of
the Exchange Offer Registration Statement (and/or, if applicable, the Shelf
Registration Statement), in the case of (i) above, (2) upon the effectiveness of
the Exchange Offer Registration Statement (and/or, if applicable, the Shelf
Registration Statement), in the case of (ii) above, (3) upon Consummation of the
Exchange Offer, in the case of (iii) above, (4) upon the filing of a
post-effective amendment to the Registration Statement or an additional
Registration Statement that causes the Exchange Offer Registration Statement
(and/or, if applicable, the Shelf Registration Statement) to again be declared
effective or made usable in the case of (iv) above, or (5) if sooner, upon the
first date on which no Transfer Restricted Securities remain outstanding, in the
case of clauses (i) through (iv) above, the liquidated damages payable with
respect to the Transfer Restricted Securities as a result of such clause (i),
(ii), (iii) or (iv), as applicable, shall cease.

         All accrued liquidated damages shall be paid to the Holders entitled
thereto, in the manner provided for the payment of interest in the Indenture, on
each Interest Payment Date, as more fully set forth in the Indenture and the
Debentures. Notwithstanding the fact that any securities for which liquidated
damages are due cease to be Transfer Restricted Securities, all obligations of
the Issuer to pay liquidated damages with respect to securities that accrued
prior to the time such securities ceased to be Transfer Restricted Securities
shall survive until such time as such obligations with respect to such
securities shall have been satisfied in full.

SECTION 6. REGISTRATION PROCEDURES

         (a)     Exchange Offer Registration Statement. In connection with the
Exchange Offer, the Issuer shall (x) comply with all applicable provisions of
Section 6(c) hereof, (y) use its reasonable best efforts to effect such exchange
and to permit the resale of Series B Debentures by Broker-Dealers that tendered
in the Exchange Offer Series A Debentures that such Broker-Dealer acquired for
its own account as a result of its market-making activities or other trading
activities (other than Series A Debentures acquired directly from the Issuer or
any of its Affiliates) being sold in accordance with the intended method or
methods of distribution thereof, and (z) comply with all of the following
provisions:

                  (i)      If, following the date hereof there has been
         announced a change in Commission policy with respect to exchange
         offers, such as the Exchange Offer, that, in the opinion of counsel to
         the Issuer, raises a substantial question as to whether the Exchange
         Offer is permitted by applicable federal law, the Issuer hereby agrees
         to seek a no-action letter or other favorable decision from the
         Commission allowing the Issuer to Consummate an Exchange Offer for such
         Transfer Restricted Securities. The Issuer hereby agrees to use its
         reasonable best efforts in pursuing the issuance of such a decision to
         the Commission staff level.




                                       6
<PAGE>   8

                  (ii)     As a condition to its participation in the Exchange
         Offer, each Holder of Transfer Restricted Securities (including,
         without limitation, any Holder who is a Broker-Dealer) shall furnish,
         upon the request of the Issuer, prior to the Consummation of the
         Exchange Offer, a written representation to the Issuer (which may be
         contained in the letter of transmittal contemplated by the Exchange
         Offer Registration Statement) to the effect that, at the time of
         Consummation of the Exchange Offer, (A) any Series B Debentures
         received by such Holder will be acquired in the ordinary course of its
         business, (B) such Holder will have no arrangement or understanding
         with any person to participate in the distribution of the Series A
         Debentures or the Series B Debentures within the meaning of the Act,
         (C) if the Holder is not a Broker-Dealer or is a Broker-Dealer but will
         not receive Series B Debentures for its own account in exchange for
         Series A Debentures, neither the Holder nor any such other Person is
         engaged in or intends to participate in a distribution of the Series B
         Debentures, and (D) that such Holder is not an Affiliate of the Issuer.
         If the Holder is a Broker-Dealer that will receive Series B Debentures
         for its own account in exchange for Series A Debentures, it will
         represent that the Debentures to be exchanged for the Series B
         Debentures were acquired by it as a result of market-making activities
         or other trading activities, and will acknowledge that it will deliver
         a prospectus meeting the requirements of the Act in connection with any
         resale of such Series B Debentures. It is understood that, by
         acknowledging that it will deliver, and by delivering, a prospectus
         meeting the requirements of the Act in connection with any resale of
         such Series B Debentures, the Holder is not admitting that it is an
         "underwriter" within the meaning of the Act.

                  (iii)    Prior to effectiveness of the Exchange Offer
         Registration Statement, the Issuer shall provide a supplemental letter
         to the Commission (A) stating that the Issuer is registering the
         Exchange Offer in reliance on the position of the Commission enunciated
         in Exxon Capital Holdings Corporation (available May 13, 1988) and
         Morgan Stanley and Co., Inc. (available June 5, 1991), as interpreted
         in the Commission's letter to Shearman & Sterling dated July 2, 1993,
         and, if applicable, any no-action letter obtained pursuant to clause
         (i) above, (B) including a representation that the Issuer has not
         entered into any arrangement or understanding with any Person to
         distribute the Series B Debentures to be received in the Exchange Offer
         and that, to the best of the Issuer's information and belief, each
         Holder participating in the Exchange Offer is acquiring the Series B
         Debentures in its ordinary course of business and has no arrangement or
         understanding with any Person to participate in the distribution of the
         Series B Debentures received in the Exchange Offer and (C) any other
         undertaking or representation required by the Commission as set forth
         in any no-action letter obtained pursuant to clause (i) above, if
         applicable.

         (b)      Shelf Registration Statement. In connection with the Shelf
Registration Statement, the Issuer shall:

                  (i)      comply with all the provisions of Section 6(c) hereof
         and use its reasonable best efforts to effect such registration to
         permit the sale of the Transfer Restricted Securities being sold in
         accordance with the intended method or methods of distribution thereof
         (as indicated in the information furnished to the Issuer pursuant to
         Section 4(b) hereof), and pursuant thereto the Issuer will prepare and
         file with the Commission a Registration Statement relating to the
         registration on any appropriate form under the Act, which form shall be
         available for the sale of the Transfer Restricted Securities in
         accordance with the intended method or methods of distribution thereof
         within the time periods and otherwise in accordance with the provisions
         hereof, and

                  (ii)     issue, upon the request of any Holder or purchaser of
         Series A Debentures covered by any Shelf Registration Statement
         contemplated by this Agreement, Series B Debentures having an aggregate
         principal amount equal to the aggregate principal amount of Series A
         Debentures sold pursuant to the Shelf Registration Statement and
         surrendered to the Issuer for cancellation; the Issuer shall register
         Series B Debentures on the Shelf Registration Statement for this
         purpose and issue the Series B Debentures to the purchaser(s) of
         securities subject to the Shelf Registration Statement in the names as
         such purchaser(s) shall designate.

         (c)      General Provisions. In connection with any Registration
Statement and any related Prospectus required by this Agreement, the Issuer
shall, during the periods specified in Sections 3 and 4 hereof, as applicable:

                  (i)      use its reasonable best efforts to keep such
         Registration Statement continuously effective and provide all requisite
         financial statements for the period specified in Section 3 or 4 of this
         Agreement, as applicable. Upon the occurrence of any event that would
         cause any such Registration Statement or the Prospectus contained
         therein (A) to contain an untrue statement of material fact or omit to
         state any material fact necessary to make the statements therein, in
         the light of the circumstances under which they were made, not
         misleading or (B) not to be effective and usable for resale of Transfer
         Restricted Securities during the period required by this Agreement, the
         Issuer shall file promptly an appropriate amendment to such
         Registration Statement or a supplement to the Prospectus, as
         applicable, curing such defect, and, in the case of an amendment, use
         its reasonable best efforts to cause such amendment to be declared
         effective as soon as practicable.

                  (ii)     prepare and file with the Commission such amendments
         and post-effective amendments to the applicable Registration Statement
         as may be necessary to keep such Registration Statement effective for
         the applicable period set forth in Section 3 or 4 hereof, as the case
         may be; cause the Prospectus to be supplemented by any required
         Prospectus supplement, and as so supplemented to be filed pursuant to
         Rule 424 under the Act, and to comply fully with Rules 424, 430A and
         462, as applicable, under the Act in a timely manner; and comply with
         the provisions of the Act with respect to the disposition of all
         securities covered by such Registration Statement during the applicable
         period in accordance with the intended method or methods of
         distribution by the sellers thereof set forth in such Registration
         Statement or supplement to the Prospectus;

                  (iii)    advise each Holder whose Transfer Restricted
         Securities have been included in a Shelf Registration Statement (in the
         case of the Shelf Registration Statement) and the Initial Purchaser
         promptly and, if requested by such Person, confirm such advice in
         writing, (A) when the Prospectus or any Prospectus supplement or
         post-effective amendment has been filed, and, with respect to any
         applicable Registration Statement or any post-effective amendment
         thereto, when the same has become effective, (B) of any request by the
         Commission for amendments to the Registration Statement or amendments
         or supplements to the Prospectus or for additional information relating
         thereto, (C) of the issuance by the Commission of any stop order
         suspending the effectiveness of the Registration Statement under the
         Act or of the suspension by any state securities commission of the
         qualification of the Transfer Restricted Securities for offering or
         sale in any jurisdiction, or the initiation of any proceeding for any
         of the preceding purposes, and (D) of the existence of any fact or the
         happening of any event that makes any statement of a material fact made
         in the Registration Statement, the Prospectus, any amendment or
         supplement thereto or any 




                                       8

         document incorporated by reference therein untrue, or that requires
         the making of any additions to or changes in the Registration
         Statement in order to make the statements therein not misleading, or
         that requires the making of any additions to or changes in the
         Prospectus in order to make the statements therein, in the light of
         the circumstances under which they were made, not misleading. If at
         any time the Commission shall issue any stop order suspending the
         effectiveness of the Registration Statement, or any state securities
         commission or other regulatory authority shall issue an order
         suspending the qualification or exemption from qualification of the
         Transfer Restricted Securities under state securities or Blue Sky
         laws, the Issuer shall use its reasonable best efforts to obtain the
         withdrawal or lifting of such order at the earliest possible time;

                  (iv)     subject to Section 6(c)(i), if any fact or event
         contemplated by Section 6(c)(iii)(D) hereof shall exist or have
         occurred, prepare a supplement or post-effective amendment to the
         Registration Statement or related Prospectus or any document
         incorporated therein by reference or file any other required document
         so that, as thereafter delivered to the purchasers of Transfer
         Restricted Securities, the Prospectus will not contain an untrue
         statement of a material fact or omit to state any material fact
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading;

                  (v)      furnish to each Holder whose Transfer Restricted
         Securities have been included in a Shelf Registration Statement (in the
         case of the Shelf Registration Statement) and the Initial Purchaser,
         before filing with the Commission, copies of any Registration Statement
         or any Prospectus included therein or any amendments or supplements to
         any such Registration Statement or Prospectus (including all documents
         incorporated by reference after the initial filing of such Registration
         Statement), which documents will be subject to the review and comment
         of such Persons, if any, for a period of at least five Business Days,
         and the Issuer will not file any such Registration Statement or
         Prospectus or any amendment or supplement to any such Registration
         Statement or Prospectus (including all such documents incorporated by
         reference) to which such Persons shall reasonably object within five
         Business Days after the receipt thereof. Such Persons shall be deemed
         to have reasonably objected to such filing if such Registration
         Statement, amendment, Prospectus or supplement, as applicable, as
         proposed to be filed, contains an untrue statement of a material fact
         or omit to state any material fact necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading or fails to comply with the applicable requirements of
         the Act;

                  (vi)     promptly prior to the filing of any document that is
         to be incorporated by reference into a Registration Statement or
         Prospectus, provide copies of such document to each Holder whose
         Transfer Restricted Securities have been included in a Shelf
         Registration Statement (in the case of the Shelf Registration
         Statement) and the Initial Purchaser, make the Issuer's representatives
         available for discussion of such document and other customary due
         diligence matters, and include such information in such document prior
         to the filing thereof as such Persons may reasonably request;

                  (vii)    make available, at reasonable times, for inspection
         by each Holder whose Transfer Restricted Securities have been included
         in a Shelf Registration Statement (in the case of the Shelf
         Registration Statement) and the Initial Purchaser and any attorney or
         accountant retained by such Persons, all financial and other records,
         pertinent corporate documents of the Issuer and cause the Issuer's
         officers, directors and employees to supply all information reasonably
         requested by any 





                                       9
<PAGE>   11

         such Persons, attorney or accountant in connection with such
         Registration Statement or any post-effective amendment thereto
         subsequent to the filing thereof and prior to its effectiveness;

                  (viii)   if requested by any Holders whose Transfer Restricted
         Securities have been included in a Shelf Registration Statement (in the
         case of the Shelf Registration Statement) or the Initial Purchaser,
         promptly include in any Registration Statement or Prospectus, pursuant
         to a supplement or post-effective amendment if necessary, such
         information as such Persons may reasonably request to have included
         therein, including, without limitation, information relating to the
         "Plan of Distribution" of the Transfer Restricted Securities and the
         use of the Registration Statement or Prospectus for market-making
         activities; and make all required filings of such Prospectus supplement
         or post-effective amendment as soon as practicable after the Issuer is
         notified of the matters to be included in such Prospectus supplement or
         post-effective amendment;

                  (ix)     furnish to each Holder whose Transfer Restricted
         Securities have been included in a Shelf Registration Statement (in the
         case of the Shelf Registration Statement) and the Initial Purchaser,
         without charge, at least one copy of the Registration Statement, as
         first filed with the Commission, and of each amendment thereto,
         including all documents incorporated by reference therein and all
         exhibits (including exhibits incorporated therein by reference);

                  (x)      deliver to each Holder whose Transfer Restricted
         Securities have been included in a Shelf Registration Statement and the
         Initial Purchaser without charge, as many copies of the Prospectus
         (including each preliminary prospectus) and any amendment or supplement
         thereto as such Persons reasonably may request; the Issuer hereby
         consents to the use (in accordance with law and subject to Section 6(d)
         hereof) of the Prospectus and any amendment or supplement thereto by
         each selling Person in connection with the offering and the sale of the
         Transfer Restricted Securities covered by the Prospectus or any
         amendment or supplement thereto and all market-making activities of the
         Initial Purchaser, as the case may be;

                  (xi)     upon the request of any Holder whose Transfer
         Restricted Securities have been included in a Shelf Registration
         Statement (in the case of the Shelf Registration Statement) or the
         Initial Purchaser, enter into such agreements (including underwriting
         agreements) and make such representations and warranties and take all
         such other actions in connection therewith in order to expedite or
         facilitate the disposition of the Transfer Restricted Securities
         pursuant to any applicable Registration Statement contemplated by this
         Agreement as may be reasonably requested by such Person in connection
         with any sale or resale pursuant to any applicable Registration
         Statement. In such connection, the Issuer shall:

                  (A)      upon request of any such Person, furnish (or in the
         case of paragraphs (2) and (3), use its reasonable best efforts to
         cause to be furnished) to each Holder whose Transfer Restricted
         Securities have been included in a Shelf Registration Statement (in the
         case of the Shelf Registration Statement) and the Initial Purchaser,
         upon Consummation of the Exchange Offer or upon the effectiveness of
         the Shelf Registration Statement, as the case may be:

                           (1)       a certificate, dated such date, signed on
                  behalf of the Issuer by (x) the President or any Vice
                  President and (y) a principal financial or accounting officer
                  of the Issuer, confirming, as of the date thereof, the matters
                  set forth in Sections 6(y), 9(a) and 9(b) of the Purchase
                  Agreement and such other similar matters as such Person may
                  reasonably request;




                                       10
<PAGE>   12

                           (2)       an opinion, dated the date of Consummation
                  of the Exchange Offer or the date of effectiveness of the
                  Shelf Registration Statement, as the case may be, of counsel
                  for the Issuer covering matters similar to those set forth in
                  Sections 9(e) and (f) of the Purchase Agreement and such other
                  matters as such Person may reasonably request, and in any
                  event including a statement to the effect that such counsel
                  has participated in conferences with officers and other
                  representatives of the Issuer, representatives of the
                  independent public accountants for the Issuer and have
                  considered the matters required to be stated therein and the
                  statements contained therein, although such counsel has not
                  independently verified the accuracy, completeness or fairness
                  of such statements; and that such counsel advises that, on the
                  basis of the foregoing (relying as to materiality to the
                  extent such counsel deems appropriate upon the statements of
                  officers and other representatives of the Issuer) and without
                  independent check or verification), no facts came to such
                  counsel's attention that caused such counsel to believe that
                  the applicable Registration Statement, at the time such
                  Registration Statement or any post-effective amendment thereto
                  became effective and, in the case of the Exchange Offer
                  Registration Statement, as of the date of Consummation of the
                  Exchange Offer, 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 therein not
                  misleading, or that the Prospectus contained in such
                  Registration Statement as of its date and, in the case of the
                  opinion dated the date of Consummation of the Exchange Offer,
                  as of the date of Consummation, contained an untrue statement
                  of a material fact or omitted to state a material fact
                  necessary in order to make the statements therein, in the
                  light of the circumstances under which they were made, not
                  misleading. Without limiting the foregoing, such counsel may
                  state further that such counsel assumes no responsibility for,
                  and has not independently verified, the accuracy, completeness
                  or fairness of the financial statements, Debentures and
                  schedules and other financial data included in any
                  Registration Statement contemplated by this Agreement or the
                  related Prospectus; and

                           (3)       a customary comfort letter, dated the date
                  of Consummation of the Exchange Offer, or as of the date of
                  effectiveness of the Shelf Registration Statement, as the case
                  may be, from the Issuer's independent accountants, in the
                  customary form and covering matters of the type customarily
                  covered in comfort letters to underwriters in connection with
                  underwritten offerings, and affirming the matters set forth in
                  the comfort letters delivered pursuant to Section 9(h) of the
                  Purchase Agreement; and

                  (B)      deliver such other documents and certificates as may
         be reasonably requested by such Persons to evidence compliance with the
         matters covered in clause (A) above and with any customary conditions
         contained in any agreement entered into by the Issuer pursuant to this
         clause (xi);

                  (xii)    prior to any public offering of Transfer Restricted
         Securities, cooperate with the selling Holders and their counsel in
         connection with the registration and qualification of the Transfer
         Restricted Securities under the securities or Blue Sky laws of such
         jurisdictions as the selling Holders may request and do any and all
         other acts or things necessary or advisable to enable 



                                       11
<PAGE>   13

         the disposition in such jurisdictions of the Transfer Restricted
         Securities covered by the applicable Registration Statement; provided
         that the Issuer shall not be required to register or qualify as a
         foreign corporation where it is not now so qualified or to take any
         action that would subject it to the service of process in suits or to
         taxation, other than as to matters and transactions relating to the
         Registration Statement, in any jurisdiction where it is not now so
         subject;

                  (xiii)   in connection with any sale of Transfer Restricted
         Securities that will result in such securities no longer being Transfer
         Restricted Securities, cooperate with the Holders to facilitate the
         timely preparation and delivery of certificates representing Transfer
         Restricted Securities to be sold and not bearing any restrictive
         legends; and to register such Transfer Restricted Securities in such
         denominations and such names as the selling Holders may request at
         least two Business Days prior to such sale of Transfer Restricted
         Securities;

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

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

                  (xvi)    otherwise use its reasonable best efforts to comply
         with all applicable rules and regulations of the Commission, and make
         generally available to its security holders with regard to any
         applicable Registration Statement, as soon as practicable, a
         consolidated earnings statement meeting the requirements of Rule 158
         (which need not be audited) covering a twelve-month period beginning
         after the effective date of the Registration Statement (as such term is
         defined in Rule 158(c) under the Act);

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

                  (xviii)  provide promptly to each Holder and the Initial
         Purchaser, upon request, each document filed with the Commission
         pursuant to the requirements of Section 13 or Section 15(d) of the
         Exchange Act.

         (d)     Restrictions on Holders. Each Holder agrees by acquisition of a
Transfer Restricted Security and the Initial Purchaser agrees that, upon receipt
of the notice referred to in Section 6(c)(iii)(C) or any notice from the Issuer
of the existence of any fact of the kind described in Section 6(c)(iii)(D)
hereof (in each case, a "Suspension Notice"), such Person will forthwith
discontinue disposition of Transfer Restricted Securities pursuant to the
applicable Registration Statement until (i) such Person has received copies of
the 




                                       12

supplemented or amended Prospectus contemplated by Section 6(c)(iv) hereof,
or (ii) such Person is advised in writing by the Issuer that the use of the
Prospectus may be resumed, and has received copies of any additional or

each case, the "Recommencement Date"). Each Person receiving a Suspension Notice
hereby agrees that it will either (i) destroy any Prospectuses, other than
permanent file copies, then in such Person's possession which have been replaced
by the Issuer with more recently dated Prospectuses or (ii) deliver to the
Issuer (at the Issuer's expense) all copies, other than permanent file copies,
then in such Person's possession of the Prospectus covering such Transfer
Restricted Securities that was current at the time of receipt of the Suspension
Notice. The time period regarding the effectiveness of such Registration
Statement set forth in Section 3 or 4 hereof, as applicable, shall be extended
by a number of days equal to the number of days in the period from and including
the date of delivery of the Suspension Notice to the date of delivery of the
Recommencement Date.

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

         (b)      In connection with any Registration Statement required by this
Agreement (including, without limitation, the Exchange Offer Registration
Statement and the Shelf Registration Statement), the Issuer will reimburse the
Initial Purchaser and the Holders of Transfer Restricted Securities who are
tendering Series A Debentures in the Exchange Offer and/or selling or reselling
Series A Debentures or Series B Debentures pursuant to the "Plan of
Distribution" contained in the Exchange Offer Registration Statement or the
Shelf Registration Statement, as applicable, for the reasonable fees and
disbursements of not more than one counsel, who shall be chosen by the Holders
of a majority in principal amount of the Transfer Restricted Securities for
whose benefit such Registration Statement is being prepared.

SECTION 8. INDEMNIFICATION

         (a)      The Issuer agrees to indemnify and hold harmless each Holder,
its directors, officers and each Person, if any, who controls such Holder
(within the meaning of Section 15 of the Act or Section 20 of the Exchange Act),
from and against any and all losses, claims, damages, liabilities, judgments,
(including, without limitation, any legal or other expenses incurred in
connection with investigating or defending any matter, including any action that
could give rise to any such losses, claims, damages, liabilities or judgments)
caused by any untrue statement or alleged untrue statement of a material fact
contained in any 




                                       13
<PAGE>   15

Registration Statement, preliminary prospectus or Prospectus (or any amendment
or supplement thereto) provided by the Issuer to any Holder or any prospective
purchaser of Series B Debentures or registered Series A Debentures, or caused by
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages, liabilities or judgments are
caused by an untrue statement or omission or alleged untrue statement or
omission that is based upon information relating to any of the Holders furnished
in writing to the Issuer by any of the Holders.

         (b)      Each Holder of Transfer Restricted Securities agrees,
severally and not jointly, to indemnify and hold harmless the Issuer, its
directors and officers, and each person, if any, who controls (within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act) the Issuer,
to the same extent as the foregoing indemnity from the Issuer set forth in
Section 8(a) hereof, but only with reference to information relating to such
Holder furnished in writing to the Issuer by such Holder expressly for use in
any Registration Statement. In no event shall any Holder, its directors,
officers or any Person who controls such Holder be liable or responsible for any
amount in excess of the amount by which the total amount received by such Holder
with respect to its sale of Transfer Restricted Securities pursuant to a
Registration Statement exceeds (i) the amount paid by such Holder for such
Transfer Restricted Securities and (ii) the amount of any damages that such
Holder, its directors, officers or any Person who controls such Holder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.

         (c)      In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying person") in
writing, and the indemnifying party shall assume the defense of such action,
including the employment of counsel reasonably satisfactory to the indemnified
party and the payment of all fees and expenses of such counsel, as incurred
(except that, in the case of any action in respect of which indemnity may be
sought pursuant to both Sections 8(a) and 8(b), a Holder shall not be required
to assume the defense of such action pursuant to this Section 8(c), but may
employ separate counsel and participate in the defense thereof, but the fees and
expenses of such counsel, except as provided below, shall be at the expense of
the Holder). Any indemnified party shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of the indemnified party,
unless (i) the employment of such counsel shall have been specifically
authorized in writing by the indemnifying party, (ii) the indemnifying party
shall have failed to assume the defense of such action or employ counsel
reasonably satisfactory to the indemnified party or (iii) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the indemnifying party, and the indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the indemnified party).
In any such case, the indemnifying party shall not, in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) for all indemnified parties and all such fees and
expenses shall be reimbursed as they are incurred. Such firm shall be designated
in writing by a majority of the Holders, in the case of the parties indemnified
pursuant to Section 8(a), and by the Issuer, in the case of parties indemnified
pursuant to Section 8(b). The indemnifying party shall indemnify and hold
harmless the indemnified party from and against any and all losses, claims,
damages, liabilities and judgments by reason of any settlement of any action (i)
effected with its written consent or (ii) effected without its written consent
if the settlement is entered into more than twenty Business Days after the
indemnifying party shall 





                                       14
<PAGE>   16

have received a request from the indemnified party for reimbursement for the
fees and expenses of counsel (in any case where such fees and expenses are at
the expense of the indemnifying party) and, prior to the date of such
settlement, the indemnifying party shall have failed to comply with such
reimbursement request. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement or compromise of, or
consent to the entry of judgment with respect to, any pending or threatened
action in respect of which the indemnified party is or could have been a party
and indemnity or contribution may be or could have been sought hereunder by the
indemnified party, unless such settlement, compromise or judgment (i) includes
an unconditional release of the indemnified party from all liability on claims
that are or could have been the subject matter of such action and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of the indemnified party.

         (d)      To the extent that the indemnification provided for in this
Section 8 is unavailable to an indemnified party in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or judgments (i) in such proportion
as is appropriate to reflect the relative benefits received by the Issuer, on
the one hand, and the Holders, on the other hand, from their sale of Transfer
Restricted Securities or (ii) if the allocation provided by clause 8(d)(i) is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause 8(d)(i) hereof but also the
relative fault of the Issuer, on the one hand, and of the Holder, on the other
hand, in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations. The relative fault of the Issuer, on the one hand, and
of the Holder, 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 Issuer, on the one hand, or by the Holder, on the
other hand, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages, liabilities or judgments referred to above shall be deemed to include,
subject to the limitations set forth in the second paragraph of Section 8(a),
any legal or other fees or expenses reasonably incurred by such indemnified
party in connection with investigating or defending any matter, including any
action that could have given rise to such losses, claims, damages, liabilities
or judgments.

         The Issuer and each Holder agree that it would not be just and
equitable if contribution pursuant to this Section 8(d) 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 in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 8, no Holder, its directors, its
officers or any Person, if any, who controls such Holder shall be required to
contribute, in the aggregate, any amount in excess of the amount by which the
total received by such Holder with respect to the sale of Transfer Restricted
Securities pursuant to a Registration Statement exceeds (i) the amount paid by
such Holder for such Transfer Restricted Securities and (ii) the amount of any
damages which such Holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. The Holders' obligations to contribute
pursuant to this Section 8(d) are several in proportion to the respective
principal amount of Transfer Restricted Securities held by each Holder hereunder
and not joint.




                                       15
<PAGE>   17

         (e)      The Issuer agrees that the indemnity and contribution
provisions of this Section 8 shall apply to the Initial Purchaser to the same
extent, on the same conditions, as it applies to Holders.

SECTION 9. RULE 144A AND RULE 144

         The Issuer agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Issuer (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder, to such Holder or beneficial owner of
Transfer Restricted Securities in connection with any sale thereof and any
prospective purchaser of such Transfer Restricted Securities designated by such
Holder or beneficial owner, the information required by Rule 144A(d)(4) under
the Act in order to permit resales of such Transfer Restricted Securities
pursuant to Rule 144A, and (ii) is subject to Section 13 or 15(d) of the
Exchange Act, to make all filings required thereby in a timely manner in order
to permit resales of such Transfer Restricted Securities pursuant to Rule 144.

SECTION 10. MISCELLANEOUS

         (a)      Remedies. The Issuer acknowledges and agrees that any failure
by the Issuer to comply with its obligations under Sections 3 and 4 hereof may
result in material irreparable injury to the Initial Purchaser or the Holders
for which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, the Initial Purchaser or any Holder may obtain such relief as may be
required to specifically enforce the Issuer's obligations under Sections 3 and 4
hereof. The Issuer further agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

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

         (c)      Amendments and Waivers. The provisions of this Agreement may
not be amended, modified or supplemented, and waivers or consents to or
departures from the provisions hereof may not be given unless (i) in the case of
Section 5 hereof and this Section 10(c)(i), the Issuer has obtained the written
consent of Holders of all outstanding Transfer Restricted Securities, and (ii)
in the case of all other provisions hereof, the Issuer has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Issuer or its Affiliates). Notwithstanding the foregoing, a waiver or consent to
departure from the provisions hereof that relates exclusively to the rights of
Holders whose Transfer Restricted Securities are being tendered pursuant to the
Exchange Offer, and that does not affect directly or indirectly the rights of
other Holders whose Transfer Restricted Securities are not being tendered
pursuant to such Exchange Offer, may be given by the Holders of a majority of
the outstanding principal amount of Transfer Restricted Securities subject to
such Exchange Offer.

         (d)      Third Party Beneficiary. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Issuer, on the one
hand, and the Initial Purchaser, on the other hand, and shall 





                                       16
<PAGE>   18

have the right to enforce such agreements directly to the extent they may deem
such enforcement necessary or advisable to protect its rights or the rights of
Holders hereunder.

         (e)      Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail

benefit of and be binding upon the successors and assigns of each of the
parties, including, without limitation, and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Transfer Restricted
Securities in violation of the terms hereof or of the Purchase Agreement or the
Indenture. If any transferee of any Holder shall acquire Transfer Restricted
Securities in any manner, whether by operation of law or otherwise, such
Transfer Restricted Securities shall be held subject to all of the terms of this
Agreement, and by taking and holding such Transfer Restricted Securities such
Person shall be conclusively deemed to have agreed to be bound by and to perform
all of the terms and provisions of this Agreement, including the restrictions on
resale set forth in this Agreement and, if applicable, the Purchase Agreement,
and such Person shall be entitled to receive the benefits hereof.

         (g)      Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken

of reference only and shall not limit or otherwise affect the meaning hereof.

         (i)      Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND

TO THE CONFLICT OF LAW RULES THEREOF.

provisions contained herein, or the application thereof in any circumstance, is

Executive Officer of Holdings and Employee agrees to be employed by Employers in
such capacities, all on the terms and conditions set forth herein. The
Employment shall be for a period (the "EMPLOYMENT PERIOD") that will (i)
commence on the Effective Date and continue for at least three years thereafter
(unless earlier terminated as provided herein) and (ii) renew on each
anniversary of the Effective Date for a three-year period, on the same terms and
conditions contained herein (unless earlier terminated as provided herein or
Employee is timely provided a notice of nonrenewal as provided herein), such
that the Employment Period shall extend for a period of three years from the
date of each such extension. The Employers must provide Employee with written
notice not less than 60 days in advance of the applicable anniversary of the
Effective Date in order to avoid renewal of the Employment Period on such
anniversary as described above. Notice shall be deemed given on the date it is
received by the Employee.

          (b) Duties. Employee shall be subject to the direction and supervision
of the Board of Directors of Holdings (the "BOARD") and, as the Chief Executive





<PAGE>   2



Officer, shall have those duties and responsibilities which are assigned to him
during the Employment Period by the Board consistent with his positions,
provided that the Board shall not assign any greater duties or responsibilities
to the Employee than are necessary to the Employee's faithful and adequate
supervision of the overall management and businesses of the Employers. The Board
shall not take any action which results in a diminution of Employee's position,
authority, duties or responsibilities as of the date hereof. The parties
expressly acknowledge that the Employee shall devote all of his business time
and attention to the transaction of the Employer's businesses as is reasonably
necessary to discharge his supervisory management responsibilities hereunder.
Employee agrees to perform faithfully the duties assigned to him to the best of
his ability.

         SECTION 2.  Compensation.

          (a) Salary. Employers shall pay to Employee during the Employment
Period a salary as basic compensation for the services to be rendered by
Employee hereunder. The initial amount of such salary shall be $538,400 per
annum. Such salary shall be reviewed no less frequently than annually by the
Board and may be increased upon the approval of the Board in its sole
discretion. Such salary shall accrue and be payable in accordance with the
payroll practices of Employers' subsidiary or subsidiaries in effect from time
to time. All such payments shall be subject to deduction and withholding
authorized or required by applicable law.

          (b) Bonus. During the Employment Period, Employee shall additionally
participate in an annual bonus plan providing for an annual bonus opportunity of
not less than 100% of Employee's annual salary.

          (c) Benefits. During the Employment Period, Employee shall be entitled
to participate in such other employee benefit plans, programs and arrangements
as are customarily accorded the executives of Employers, including without
limitation, tax qualified profit sharing and retirement plans, group life,
hospitalization and other insurance and vacations (but excluding stock option
and other stock- or equity-based compensation plans), on a basis no less
favorable than as of the date of this Agreement. Without limiting the foregoing,
the employee benefit plans, programs and arrangements in which Employee shall be
entitled to participate during the Employment Period shall be no less generous,
in the aggregate, than those in which such Employee was entitled to participate
immediately prior to the consummation of the merger between Holdings and Mercury
Acquisition Corporation.

         SECTION 3.  Termination.

          (a) Death or Disability. Employment of Employee under this Agreement
shall terminate automatically upon the death or total disability of Employee.
For the purpose of this Agreement, "TOTAL DISABILITY" shall be deemed to have
occurred if Employee shall have been unable to perform the duties of his
Employment due to mental or physical incapacity for a period of six (6)
consecutive months.

          (b) Cause. The Board may terminate the Employment of Employee under
this Agreement for Cause. For the purposes of this Agreement, "CAUSE" shall be
deemed to be (i) dishonesty by Employee that results in substantial personal
enrichment at the expense of the Employers or (ii) demonstratively willful
repeated violations of Employee's obligations under this Agreement which are
intended to result in material injury to the Employers.

          (c) Without Cause. Any of the Employers, acting alone, may terminate
the Employment of Employee under this Agreement without Cause.

          (d) Constructive Termination. Employee may elect to terminate his
Employment under this Agreement upon a Constructive Termination Without Cause,
as defined below. For purposes of this Agreement, "CONSTRUCTIVE TERMINATION
WITHOUT CAUSE" shall mean a termination of the Employee's employment at his
initiative following the occurrence, without the Employee's prior written
consent, of one or more of the following events:

                   (i) receipt of notice from the Employers that the Employment
          Period shall not be renewed as described in Section 1(a) above;

                   (ii) any failure by the Employers to comply with any of the 
          provisions of the Employment Agreement, other than an isolated,
          insubstantial and inadvertent failure not occurring in bad faith and
          which is remedied by the Employers promptly after receipt of notice
          thereof given by the Employee;

                   (iii) any reduction in any form of compensation, fringe 
          benefit, deferred compensation plan or perquisite applicable to the
          Employee immediately prior to the effective time of the Employment
          Agreement, including any reduction in salary or any reduction in bonus
          percentage to less than the average of such bonus percentage for the
          two fiscal years immediately preceding the effective time of the
          Employment Agreement;





                                       3
<PAGE>   4



                  (iv) the loss of any of the Employee's titles or positions in
          effect at the effective time of the Employment Agreement;

                  (v) any change in the position to which the Employee reports 
          or the positions that report to the Employee at the effective time of
          the Employment Agreement (reporting relationships);

                  (vi) the assignment to the Employee of any duties 
          inconsistent in any respect with the Employee's position (including
          status, offices, titles and reporting relationships), authority,
          duties or responsibilities as in effect at the effective time of the
          Employment Agreement, or any other action by the Employers which
          results in a diminution in such position, authority, duties or
          responsibilities excluding an isolated, insubstantial and inadvertent
          action not taken in bad faith and which is remedied by the Employers
          promptly after receipt of notice thereof given by the Employee;

                  (vii) the relocation of the Employee's office location as 
          assigned to him by the Employers, to a location more than 25 miles
          from his office location at the effective time of the Employment
          Agreement;

                  (viii) any purported termination by the Employers of the 
          Employee's employment otherwise than as expressly permitted by Section
          3(b) of this Agreement;

                  (ix) any failure by the Employers to comply with and satisfy 
          the provisions of Section 6 hereof, or failure by any successor
          (whether direct or indirect, by purchase, merger, consolidation or
          otherwise) to all or substantially all of the business and/or assets
          of the Employers to assume expressly and agree to perform the
          Employment Agreement in the same manner and to the same extent the
          Employers would be required to perform it if no such succession had
          taken place, provided, in either case, that the successor contemplated
          by Section 6 hereof has received, at least 10 days prior to the giving
          of notice of constructive termination by the Employee, written notice
          from the Employers or the Employee of the requirements of the
          provisions of Section 6 or of such failure;

                  (x) the removal or election or employment of any officer or 
          employee of the Employers without Employee's concurrence; and

                  (xi) failure to reelect Employee as both a member of the 
          Board and the Chairman of the Board or the removal of Employee as a
          member of the Board or as Chairman of the Board.

For purposes of this Agreement any good faith determination of "Constructive
Termination Without Cause" made by the Employee shall be conclusive.

         SECTION 4.  Compensation Following Termination.

          (a) Death or Disability. If the Employment Period is terminated
pursuant to the provisions of Section 3(a) above, this Agreement shall
terminate, and no further compensation shall be payable to Employee except that
Employee or Employee's estate, heirs or beneficiaries, as applicable, shall be
entitled, in addition to any other benefits to which Employee is or may become
entitled under any benefit plan, to receive Employee's then current basic
compensation, plus an amount in lieu of bonus, which amount shall be determined
as the average bonus received by Employee for the appropriate period (prorated
for partial portions thereof) for the previous 24 months hereunder and all other
benefits to which Employee would otherwise be entitled hereunder during the
Employment Period for a period of 24 months from the date the Employment Period
terminates.

          (b) Termination for Cause or Voluntary Termination. If the Employment
Period is terminated for Cause or voluntarily by the Employee for reasons other
than those described in Section 3(a) or 3(d) above, no further compensation or
benefits shall be paid to Employee after the date of termination, but Employee
shall be entitled to receive benefits to which he is or may become entitled
pursuant to any benefit plan.

          (c) Termination Without Cause; Constructive Termination. If the
Employment Period is terminated pursuant to Section 3(c) or 3(d)above, Employee
shall be entitled to continue to receive from Employers his then current basic
compensation hereunder, plus an amount in lieu of bonus, which amount shall be
determined as the average bonus received by Employee for the appropriate period
(prorated for partial portions thereof) for the previous 24 months, such amount
to continue to be paid in accordance with the payroll practices of Employers for
a period equal to the period remaining in the Employment Period immediately
prior to such termination and Employee shall further be entitled during such
period both to continue to receive the benefits to which he would otherwise be
entitled during the Employment Period pursuant to Section above and to
reimbursement for expenses incurred by Employee to own and maintain an
automobile as contemplated by Section below. Such continuation of compensation,
benefits and automobile expenses shall continue for the period described above
notwithstanding any earlier death or reemployment of Employee.

         SECTION 5.  Expense Reimbursement.  Upon the submission of properly
documented expense account reports, Employers shall reimburse Employee for all
reasonable business-related travel and entertainment expenses incurred by




                                       5
<PAGE>   6



Employee in the course of his Employment with Employers and for expenses
incurred by Employee to own and maintain an automobile.

         SECTION 6. Assignability; Binding Nature. This Agreement shall be
binding and inure to the benefit of the parties, and their respective
successors, heirs (in the case of Employee) and assigns. No obligations of the
Employers under this Agreement may be assigned or transferred by the Employers
except that such obligations shall be assigned or transferred (as described
below) pursuant to a merger or consolidation of Holdings in which Holdings is
not the continuing entity, or the sale or liquidation of all or substantially
all of the assets of the Employers, provided that the assignee or transferee is
the surviving entity or successor to all or substantially all of the assets of
the Employers and such assignee or transferee assumes the liabilities,
obligations and duties of the Employers, as contained in this Agreement, either
contractually or as a matter of law. As used in this Agreement, the "Employers"
and "Holdings" shall mean the Employers and Holdings as hereinbefore defined,
respectively, and any successor to their business and/or assets as aforesaid
which assumes and agrees to perform this Agreement by operation of law, or
otherwise.

         SECTION 7.  Confidential Information.

          (a) Non-Disclosure. During the Employment Period or at any time
thereafter, irrespective of the time, manner or cause of the termination of this
Agreement, Employee will not directly or indirectly reveal, divulge, disclose or
communicate to any person or entity, other than authorized officers, directors
and employees of the Employers, in any manner whatsoever, any Confidential
Information (as hereinafter defined) of Employers or any subsidiary of Employers
without the prior written consent of the Board.

          (b) Definition. As used herein, "CONFIDENTIAL INFORMATION" means
information disclosed to or known by Employee as a direct or indirect
consequence of or through the Employment about Employers or any subsidiary of
Employers, or their respective businesses, products and practices which
information is not generally known in the business in which Employers or any
subsidiary of Employers is or may be engaged. However, Confidential Information
shall not include under any circumstances any information with respect to the
foregoing matters which is (i) available to the public from a source other than
Employee, (ii) released in writing by Employers to the public or to persons who
are not under a similar obligation of confidentiality to Employers and who are
not parties to this Agreement, (iii) obtained by Employee from a third party not
under a similar obligation of confidentiality to Employers, (iv) required to be
disclosed by any court process or any government or agency or department




                                       6
<PAGE>   7



of any government, or (v) the subject of a written waiver executed by either
Employers for the benefit of Employee.

          (c) Return of Property. Upon termination of the Employment, Employee
will surrender to Employers all Confidential Information, including without
limitation, all lists, charts, schedules, reports, financial statements, books
and records of the Employers or any subsidiary of the Employers, and all copies
thereof, and all other property belonging to the Employers or any subsidiary of
the Employers, provided Employee shall be accorded reasonable access to such
Confidential Information subsequent to the Employment Period for any proper
purpose as determined in the reasonable judgment of any of the Employers.

         SECTION 8.  Agreement Not to Compete.

          (a) Termination for Cause. In the event that the Employee is
terminated for Cause or voluntarily terminates his Employment with Employers
other than as a constructive termination, Employee hereby agrees that for a
period of one (1) year following such termination, he shall not, either in his
own behalf or as a partner, officer, director, employee, agent or shareholder
(other than as the holder of less than 5% of the outstanding capital stock of
any corporation with a class of equity security registered under Section 12(b)
or Section 12(g) of the Securities Exchange Act of 1934, as amended) engage in,
invest in or render services to any person or entity engaged in the businesses
in which Employers or any subsidiary of Employers are then engaged and situated
within any country. Nothing contained in this Section 8(a) shall be construed as
restricting the Employee's right to sell or otherwise dispose of any business or
investments owned or operated by Employee as of the date hereof.

          (b) Termination Without Cause or for Disability; Constructive
Termination. In the event that the Employment of Employee is terminated by
Employers without Cause or as a result of the total disability of Employee or by
Employee as a constructive termination, Employee hereby agrees that during the
period that Employee accepts payments from the Employers pursuant to Section or
Section above, as applicable, neither he nor any affiliate shall, either in his
own behalf or as a partner, officer, director, employee, agent or shareholder
(other than as the holder of less than 5% of the outstanding capital stock of
any corporation with a class of equity security registered under Section 12(b)
or Section 12(g) of the Securities Exchange Act of 1934, as amended) engage in,
invest in or render services to any person or entity engaged in the businesses
in which Employers or any subsidiary of Employers is then engaged and situated
within any country. Nothing contained in this Section 8(b) shall be construed as
restricting the Employee's right to sell or otherwise dispose of any business or
investments owned or operated by Employee as of the date hereof. In the event of




                                       7
<PAGE>   8



Employee's violation of the provisions of Section 8(b), the right of Employee to
receive any further payment pursuant to Section 4(a) or 4(c) above, as
applicable, shall immediately terminate and the Employers shall be entitled to
secure reimbursement from Employee for all payments made to Employee subsequent
to the date of any such violation. The parties hereto hereby acknowledge and
agree that the provisions of the immediately preceding sentence shall be the
sole and exclusive remedy of the Employers in respect of any violation of this
Section 8(b).

         SECTION 9. Agreement Not to Solicit Employees. Employee agrees that,
for a period of three (3) years following the termination of the Employment
Period, other than by Employers without Cause or as a result of the total
disability of Employee or by Employee as a constructive termination, and only by
reason of voluntary termination or termination for Cause, neither he nor any
affiliate shall, on behalf of any business engaged in a business competitive
with Employers or any subsidiary of Employers, solicit or induce, or in any
manner attempt to solicit or induce, any person employed by, or any agent of,
either of Employers or any subsidiary of Employers to terminate his employment
or agency, as the case may be, with either of Employers or such subsidiary;
provided that such limitations shall not apply if the contact with the Employee
or consultant is initiated by a third party on a "blind basis" such as through a
head hunter.

         SECTION 10. No Violation. Employee hereby represents and warrants to
Employers that the execution, delivery and performance of this Agreement by
Employee does not, with or without the giving of notice or the passage of time,
or both, conflict with, result in a default, right to accelerate or loss of
rights under any provision of any agreement or understanding to which the
Employee or, to the best knowledge of Employee, any of Employee's affiliates are
a party or by which Employee, or to the best knowledge of Employee, Employee's
affiliates may be bound or affected.

         SECTION 11.  Captions.  The captions, headings and arrangements used in
this Agreement are for convenience only and do not in any way affect, limit or
amplify the provisions hereof.

         SECTION 12. Notices. All notices required or permitted to be given
hereunder shall be in writing and shall be deemed delivered, whether or not
actually received, two days after deposited in the United States mail, postage
prepaid, registered or certified mail, return receipt requested, addressed to
the party to whom notice is being given at the specified address or at such
other address as such party may designate by notice:

exercise any right or power hereunder shall impair such right or power to be

and not in lieu of any other remedies available to any party at law, in equity
or otherwise.

         WHEREAS, Employee desires to continue to be employed by Employers and

earlier terminated as provided herein or Employee is timely provided a notice
of nonrenewal as provided herein), such that the Employment Period shall extend
for a period of three years from the date of each such extension.  The
Employers must provide Employee with written notice not less than 60 days in
advance of the applicable anniversary of the Effective Date in order to avoid
renewal of the Employment Period on such anniversary as described above. Notice
shall be deemed given on the date it is received by the Employee.

         (b)   Duties.  Employee shall be subject to the direction and
supervision of the Board of Directors of Holdings (the "BOARD") and, as the
Chief Financial Officer of Holdings, shall have those duties and
responsibilities which are
<PAGE>   2
assigned to him during the Employment Period by the Board consistent with his
positions, provided that the Board shall not assign any greater duties or
responsibilities to the Employee than are necessary to the Employee's faithful
and adequate supervision of the overall management and businesses of the
Employers.  The Board shall not take any action which results in a diminution
of Employee's position, authority, duties or responsibilities as of the date
hereof.  The parties expressly acknowledge that the Employee shall devote all
of his business time and attention to the transaction of the Employer's
businesses as is reasonably necessary to discharge his supervisory management
responsibilities hereunder.  Employee agrees to perform faithfully the duties
assigned to him to the best of his ability.

         SECTION 2.  Compensation.

         (a)   Salary.  Employers shall pay to Employee during the Employment 
Period a salary as basic compensation for the services to be rendered by
Employee hereunder.  The initial amount of such salary shall be $290,175 per
annum.  Such salary shall be reviewed no less frequently than annually by the
Board and may be increased upon the approval of the Board in its sole
discretion.  Such salary shall accrue and be payable in accordance with the
payroll practices of Employers' subsidiary or subsidiaries in effect from time
to time.  All such payments shall be subject to deduction and withholding
authorized or required by applicable law.

         (b)   Bonus.  During the Employment Period, Employee shall 
additionally participate in an annual bonus plan providing for an annual bonus
opportunity of not less than 75% of Employee's annual salary.

         (c)   Benefits.  During the Employment Period, Employee shall be 
entitled to participate in such other employee benefit plans, programs and
arrangements as are customarily accorded the executives of Employers, including
without limitation, tax qualified profit sharing and retirement plans, group
life, hospitalization and other insurance and vacations (but excluding stock
option and other stock- or equity-based compensation plans), on a basis no less
favorable than as of the date of this Agreement.  Without limiting the
foregoing, the employee benefit plans, programs and arrangements in which
Employee shall be entitled to participate during the Employment Period shall be
no less generous, in the aggregate, than those in which such Employee was
entitled to participate immediately prior to the consummation of the merger
between Holdings and Mercury Acquisition Corporation.

         SECTION 3.  Termination.

         (a)   Death or Disability.  Employment of Employee under this 
Agreement shall terminate automatically upon the death or total disability of
Employee.  For the purpose of this Agreement, "TOTAL DISABILITY" shall be
deemed to have occurred if Employee shall have been unable to perform the
duties of his Employment due to mental or physical incapacity for a period of
six (6) consecutive months.

         (b)   Cause.  The Board may terminate the Employment of Employee 
under this Agreement for Cause.  For the purposes of this Agreement, "CAUSE"
shall be deemed to be (i) dishonesty by Employee that results in substantial
personal enrichment at the expense of the Employers or (ii) demonstratively
willful repeated violations of Employee's obligations under this Agreement
which are intended to result in material injury to the Employers.

         (c)   Without Cause.  Any of the Employers, acting alone, may 
terminate the Employment of Employee under this Agreement without Cause.

         (d)   Constructive Termination.  Employee may elect to terminate his 
Employment under this Agreement upon a Constructive Termination Without Cause,
as defined below.  For purposes of this Agreement, "CONSTRUCTIVE TERMINATION
WITHOUT CAUSE" shall mean a termination of the Employee's employment at his
initiative following the occurrence, without the Employee's prior written
consent, of one or more of the following events:

               (i)    receipt of notice from the Employers that the Employment
         Period shall not be renewed as described in Section 1(a) above;

               (ii)   any failure by the Employers to comply with any of the 
         provisions of the Employment Agreement, other than an isolated,
         insubstantial and inadvertent failure not occurring in bad faith and
         which is remedied by the Employers promptly after receipt of notice
         thereof given by the Employee;

               (iii)   any reduction in any form of compensation, fringe 
         benefit, deferred compensation plan or perquisite applicable to the
         Employee immediately prior to the effective time of the Employment
         Agreement, including any reduction in salary or any reduction in bonus
         percentage to less than the average of such bonus percentage for the
         two fiscal years immediately preceding the effective time of the
         Employment Agreement;





                                       3
<PAGE>   4
               (iv)   the loss of any of the Employee's titles or positions in
         effect at the effective time of the Employment Agreement;

               (v)   any change in the position to which the Employee reports
         or the positions that report to the Employee at the effective time of
         the Employment Agreement (reporting relationships);

               (vi)   the assignment to the Employee of any duties inconsistent
         in any respect with the Employee's position (including status,
         offices, titles and reporting relationships), authority, duties or
         responsibilities as in effect at the effective time of the Employment
         Agreement, or any other action by the Employers which results in a
         diminution in such position, authority, duties or responsibilities
         excluding an isolated, insubstantial and inadvertent action not taken
         in bad faith and which is remedied by the Employers promptly after
         receipt of notice thereof given by the Employee;


               (vii)   the relocation of the Employee's office location as 
         assigned to him by the Employers, to a location more than 25 miles
         from his office location at the effective time of the Employment
         Agreement;

               (viii)   any purported termination by the Employers of the 
         Employee's employment otherwise than as expressly permitted by Section
         3(b) of this Agreement;

               (ix)   any failure by the Employers to comply with and satisfy 
         the provisions of Section 6 hereof, or failure by any successor
         (whether direct or indirect, by purchase, merger, consolidation or
         otherwise) to all or substantially all of the business and/or assets
         of the Employers to assume expressly and agree to perform the
         Employment Agreement in the same manner and to the same extent the
         Employers would be required to perform it if no such succession had
         taken place, provided, in either case, that the successor contemplated
         by Section 6 hereof has received, at least 10 days prior to the giving
         of notice of constructive termination by the Employee, written notice
         from the Employers or the Employee of the requirements of the
         provisions of Section 6 or of such failure;
               
               (x)   failure to reelect Employee as a member of the Board of 
         Directors or the removal of Employee as a member of the Board; and

               (xi)   the removal or Constructive Termination without cause of 
         the person who serves as Chairman of the Board or the person who
         serves as Chief Executive Officer of Holdings at the effective time of
         the Employment Agreement from either such position.





                                       4
<PAGE>   5
For purposes of this Agreement any good faith determination of "Constructive
Termination Without Cause" made by the Employee shall be conclusive.

         SECTION 4.  Compensation Following Termination.

         (a)   Death or Disability.  If the Employment Period is terminated 
pursuant to the provisions of Section 3(a) above, this Agreement shall
terminate, and no further compensation shall be payable to Employee except that
Employee or Employee's estate, heirs or beneficiaries, as applicable, shall be
entitled, in addition to any other benefits to which Employee is or may become
entitled under any benefit plan, to receive Employee's then current basic
compensation, plus an amount in lieu of bonus, which amount shall be determined
as the average bonus received by Employee for the appropriate period (prorated
for partial portions thereof) for the previous 24 months hereunder and all
other benefits to which Employee would otherwise be entitled hereunder during
the Employment Period for a period of 24 months from the date the Employment
Period terminates.

         (b)   Termination for Cause or Voluntary Termination.  If the 
Employment Period is terminated for Cause or voluntarily by the Employee for
reasons other than those described in Section 3(a) or 3(d) above, no further
compensation or benefits shall be paid to Employee after the date of
termination, but Employee shall be entitled to receive benefits to which he is
or may become entitled pursuant to any benefit plan.

         (c)   Termination Without Cause; Constructive Termination.  If the 
Employment Period is terminated pursuant to Section 3(c) or 3(d) above,
Employee shall be entitled to continue to receive from Employers his then
current basic compensation hereunder, plus an amount in lieu of bonus, which
amount shall be determined as the average bonus received by Employee for the
appropriate period (prorated for partial portions thereof) for the previous 24
months, such amount to continue to be paid in accordance with the payroll
practices of Employers for a period equal to the period remaining in the
Employment Period immediately prior to such termination and Employee shall
further be entitled during such period both to continue to receive the benefits
to which he would otherwise be entitled during the Employment Period pursuant
to Section 2(c) above and to reimbursement for expenses incurred by Employee to
own and maintain an automobile as contemplated by Section 5 below.  Such
continuation of compensation, benefits and automobile expenses shall continue
for the period described above notwithstanding any earlier death or
reemployment of Employee.





                                       5
<PAGE>   6
         SECTION 5.  Expense Reimbursement.  Upon the submission of properly
documented expense account reports, Employers shall reimburse Employee for all
reasonable business-related travel and entertainment expenses incurred by
Employee in the course of his Employment with Employers and for expenses
incurred by Employee to own and maintain an automobile.

         SECTION 6.  Assignability; Binding Nature.  This Agreement shall be 
binding and inure to the benefit of the parties, and their respective
successors, heirs (in the case of Employee) and assigns.  No obligations of the
Employers under this Agreement may be assigned or transferred by the Employers
except that such obligations shall be assigned or transferred (as described
below) pursuant to a merger or consolidation of Holdings in which Holdings is
not the continuing entity, or the sale or liquidation of all or substantially
all of the assets of the Employers, provided that the assignee or transferee is
the surviving entity or successor to all or substantially all of the assets of
the Employers and such assignee or transferee assumes the liabilities,
obligations and duties of the Employers, as contained in this Agreement, either
contractually or as a matter of law.  As used in this Agreement, the
"Employers" and "Holdings" shall mean the Employers and Holdings as
hereinbefore defined, respectively, and any successor to their business and/or
assets as aforesaid which assumes and agrees to perform this Agreement by
operation of law, or otherwise.

         SECTION 7.  Confidential Information.

         (a)   Non-Disclosure.   During the Employment Period or at any time
thereafter, irrespective of the time, manner or cause of the termination of
this Agreement, Employee will not directly or indirectly reveal, divulge,
disclose or communicate to any person or entity, other than authorized
officers, directors and employees of the Employers, in any manner whatsoever,
any Confidential Information (as hereinafter defined) of Employers or any
subsidiary of Employers without the prior written consent of the Board.

         (b)   Definition.  As used herein, "CONFIDENTIAL INFORMATION" means 
information disclosed to or known by Employee as a direct or indirect
consequence of or through the Employment about Employers or any subsidiary of
Employers, or their respective businesses, products and practices which
information is not generally known in the business in which Employers or any
subsidiary of Employers is or may be engaged.  However, Confidential
Information shall not include under any circumstances any information with
respect to the foregoing matters which is (i) available to the public from a
source other than Employee, (ii) released in writing by Employers to the public
or to persons who are not under a similar obligation of confidentiality to
Employers and who are not parties to this Agreement, (iii) obtained by Employee
from a third





                                       6
<PAGE>   7
party not under a similar obligation of confidentiality to Employers, (iv)
required to be disclosed by any court process or any government or agency or
department of any government, or (v) the subject of a written waiver executed
by either Employers for the benefit of Employee.

         (c)   Return of Property.  Upon termination of the Employment, 
Employee will surrender to Employers all Confidential Information, including
without limitation, all lists, charts, schedules, reports, financial
statements, books and records of the Employers or any subsidiary of the
Employers, and all copies thereof, and all other property belonging to the
Employers or any subsidiary of the Employers, provided Employee shall be
accorded reasonable access to such Confidential Information subsequent to the
Employment Period for any proper purpose as determined in the reasonable
judgment of any of the Employers.

         SECTION 8.  Agreement Not to Compete.

         (a)   Termination for Cause.  In the event that the Employee is 
terminated for Cause or voluntarily terminates his Employment with Employers
other than as a constructive termination, Employee hereby agrees that for a
period of one (1) year following such termination, he shall not, either in his
own behalf or as a partner, officer, director, employee, agent or shareholder
(other than as the holder of less than 5% of the outstanding capital stock of
any corporation with a class of equity security registered under Section 12(b)
or Section 12(g) of the Securities Exchange Act of 1934, as amended) engage in,
invest in or render services to any person or entity engaged in the businesses
in which Employers or any subsidiary of Employers are then engaged and situated
within any country.  Nothing contained in this Section 8(a) shall be construed
as restricting the Employee's right to sell or otherwise dispose of any
business or investments owned or operated by Employee as of the date hereof.

         (b)   Termination Without Cause or for Disability; Constructive 
Termination.  In the event that the Employment of Employee is terminated by
Employers without Cause or as a result of the total disability of Employee or
by Employee as a constructive termination, Employee hereby agrees that during
the period that Employee accepts payments from the Employers pursuant to
Section 4(a) or Section 4(c) above, as applicable, neither he nor any affiliate
shall, either in his own behalf or as a partner, officer, director, employee,
agent or shareholder (other than as the holder of less than 5% of the
outstanding capital stock of any corporation with a class of equity security
registered under Section 12(b) or Section 12(g) of the Securities Exchange Act
of 1934, as amended) engage in, invest in or render services to any person or
entity engaged in the businesses in which Employers or any subsidiary of
Employers is then engaged and situated within any country. Nothing contained in
this Section 8(b) shall be construed as





                                       7
<PAGE>   8
restricting the Employee's right to sell or otherwise dispose of any business
or investments owned or operated by Employee as of the date hereof.  In the
event of Employee's violation of the provisions of Section 8(b), the right of
Employee to receive any further payment pursuant to Section 4(a) or 4(c) above,
as applicable, shall immediately terminate and the Employers shall be entitled
to secure reimbursement from Employee for all payments made to Employee
subsequent to the date of any such violation.  The parties hereto hereby
acknowledge and agree that the provisions of the immediately preceding sentence
shall be the sole and exclusive remedy of the Employers in respect of any
violation of this Section 8(b).

         SECTION 9.  Agreement Not to Solicit Employees.  Employee agrees that,
for a period of three (3) years following the termination of the Employment
Period, other than by Employers without Cause or as a result of the total
disability of Employee or by Employee as a constructive termination, and only
by reason of voluntary termination or termination for Cause, neither he nor any
affiliate shall, on behalf of any business engaged in a business competitive
with Employers or any subsidiary of Employers, solicit or induce, or in any
manner attempt to solicit or induce, any person employed by, or any agent of,
either of Employers or any subsidiary of Employers to terminate his employment
or agency, as the case may be, with either of Employers or such subsidiary;
provided that such limitations shall not apply if the contact with the Employee
or consultant is initiated by a third party on a "blind basis" such as through
a head hunter.

         SECTION 10.  No Violation.  Employee hereby represents and warrants to
Employers that the execution, delivery and performance of this Agreement by
Employee does not, with or without the giving of notice or the passage of time,
or both, conflict with, result in a default, right to accelerate or loss of
rights under any provision of any agreement or understanding to which the
Employee or, to the best knowledge of Employee, any of Employee's affiliates
are a party or by which Employee, or to the best knowledge of Employee,
Employee's affiliates may be bound or affected.

         SECTION 11.  Captions.  The captions, headings and arrangements used in
this Agreement are for convenience only and do not in any way affect, limit or
amplify the provisions hereof.

         SECTION 12.  Notices.  All notices required or permitted to be given
hereunder shall be in writing and shall be deemed delivered, whether or not
actually received, two days after deposited in the United States mail, postage
prepaid, registered or certified mail, return receipt requested, addressed to
the party to whom notice is being given at the specified address or at such
other address as such party may designate by notice:

         SECTION 15.  Waiver.  No delay or omission by any party hereto to 
exercise any right or power hereunder shall impair such right or power to be
construed as a waiver thereof.  A waiver by any of the parties hereto of any of
the covenants to be performed by any other party or any breach thereof shall
not be construed to be a waiver of any succeeding breach thereof or of any
other covenant herein contained.  Except as otherwise expressly set forth
herein, all remedies provided for in this Agreement shall be cumulative and in
addition to and not in lieu of any other remedies available to any party at
law, in equity or otherwise.

during any time when payments are due as provided herein, or in the event
Employee fails to so designate, or withdraws all such designations, said
payments thereafter shall be made to the Employee or to Employee's estate.

         SECTION 19.  Prior Employment Agreement.  This Agreement supersedes

                         EXECUTIVE EMPLOYMENT AGREEMENT

         This Agreement is made and entered into as of May 22, 1998, (the
EFFECTIVE DATE") by and among Thermadyne Holdings Corporation, a Delaware
corporation ("HOLDINGS"), together with its subsidiaries as herein defined (all
called the "EMPLOYERS") and Stephanie N. Josephson ("EMPLOYEE").

                                   WITNESSETH:

         WHEREAS, Employers desire to continue to employ Employee upon the
terms set forth herein;

         WHEREAS, Employee desires to continue to be employed by Employers and
to appropriately memorialize the terms and conditions of such employment;

         WHEREAS, Holdings is entering into this Agreement by and on behalf of
itself and each trade or business in which its ownership and the value or voting
power is at least 50% (the "SUBSIDIARIES");

         NOW THEREFORE, Employee and Employers, in consideration of the
agreements, covenants and conditions herein, hereby agree as follows:

         SECTION 1.  Basic Employment Provisions.

          (a) Employment and Term. Employers hereby employ Employee (hereinafter
referred to as the "EMPLOYMENT") as Vice President and General Counsel of
Holdings and Employee agrees to be employed by Employers in such capacities, all

and continue for at least three years thereafter (unless earlier terminated as
provided herein) and (ii) renew on each anniversary of the Effective Date for a
three-year period, on the same terms and conditions contained herein (unless
earlier terminated as provided herein or Employee is timely provided a notice of
nonrenewal as provided herein), such that the Employment Period shall extend for
a period of three years from the date of each such extension. The Employers must
provide Employee with written notice not less than 60 days in advance of the

Employment Period on such anniversary as described above. Notice shall be deemed
given on the date it is received by the Employee.

          (b) Duties. Employee shall be subject to the direction and supervision
of the Board of Directors of Holdings (the "BOARD") and, as the Vice President
and General Counsel of Holdings, shall have those duties and responsibilities

are assigned to him during the Employment Period by the Board consistent with
his positions, provided that the Board shall not assign any greater duties or
responsibilities to the Employee than are necessary to the Employee's faithful
and adequate supervision of the overall management and businesses of the
Employers. The Board shall not take any action which results in a diminution of
Employee's position, authority, duties or responsibilities as of the date
hereof. The parties expressly acknowledge that the Employee shall devote all of
his business time and attention to the transaction of the Employer's businesses
as is reasonably necessary to discharge his supervisory management
responsibilities hereunder. Employee agrees to perform faithfully the duties
assigned to him to the best of his ability.

         SECTION 2.  Compensation.

          (a) Salary. Employers shall pay to Employee during the Employment
Period a salary as basic compensation for the services to be rendered by
Employee hereunder. The initial amount of such salary shall be $175,000 per
annum. Such salary shall be reviewed no less frequently than annually by the
Board and may be increased upon the approval of the Board in its sole
discretion. Such salary shall accrue and be payable in accordance with the
payroll practices of Employers' subsidiary or subsidiaries in effect from time
to time. All such payments shall be subject to deduction and withholding
authorized or required by applicable law.

          (b) Bonus. During the Employment Period, Employee shall additionally
participate in an annual bonus plan providing for an annual bonus opportunity of
not less than 55% of Employee's annual salary.

          (c) Benefits. During the Employment Period, Employee shall be entitled
to participate in such other employee benefit plans, programs and arrangements
as are customarily accorded the executives of Employers, including without
limitation, tax qualified profit sharing and retirement plans, group life,
hospitalization and other insurance and vacations (but excluding stock option
and other stock- or equity-based compensation plans), on a basis no less
favorable than as of the date of this Agreement. Without limiting the foregoing,
the employee benefit plans, programs and arrangements in which Employee shall be
entitled to participate during the Employment Period shall be no less generous,
in the aggregate, than those in which such Employee was entitled to participate
immediately prior to the consummation of the merger between Holdings and Mercury
Acquisition Corporation.

         SECTION 3.  Termination.

          (a) Death or Disability. Employment of Employee under this Agreement
shall terminate automatically upon the death or total disability of Employee.
For the purpose of this Agreement, "TOTAL DISABILITY" shall be deemed to have

Employment due to mental or physical incapacity for a period of six (6)
consecutive months.

          (b) Cause. The Board may terminate the Employment of Employee under
this Agreement for Cause. For the purposes of this Agreement, "CAUSE" shall be
deemed to be (i) dishonesty by Employee that results in substantial personal
enrichment at the expense of the Employers or (ii) demonstratively willful
repeated violations of Employee's obligations under this Agreement which are
intended to result in material injury to the Employers.

          (c) Without Cause. Any of the Employers, acting alone, may terminate
the Employment of Employee under this Agreement without Cause.

          (d) Constructive Termination. Employee may elect to terminate his
Employment under this Agreement upon a Constructive Termination Without Cause,
as defined below. For purposes of this Agreement, "CONSTRUCTIVE TERMINATION
WITHOUT CAUSE" shall mean a termination of the Employee's employment at his
initiative following the occurrence, without the Employee's prior written
consent, of one or more of the following events:

                   (i) receipt of notice from the Employers that the Employment
         Period shall not be renewed as described in Section 1(a) above;

                   (ii) any failure by the Employers to comply with any of the
         provisions of the Employment Agreement, other than an isolated,
         insubstantial and inadvertent failure not occurring in bad faith and
         which is remedied by the Employers promptly after receipt of notice
         thereof given by the Employee;

                   (iii) any reduction in any form of compensation, fringe
         benefit, deferred compensation plan or perquisite applicable to the
         Employee immediately prior to the effective time of the Employment
         Agreement, including any reduction in salary or any reduction in bonus
         percentage to less than the average of such bonus percentage for the
         two fiscal years immediately preceding the effective time of the
         Employment Agreement;





                                       3

<PAGE>   4



                   (iv) the loss of any of the Employee's titles or positions in
         effect at the effective time of the Employment Agreement;

                   (v) any change in the position to which the Employee reports
         or the positions that report to the Employee at the effective time of
         the Employment Agreement (reporting relationships);

                   (vi) the assignment to the Employee of any duties
         inconsistent in any respect with the Employee's position (including
         status, offices, titles and reporting relationships), authority, duties
         or responsibilities as in effect at the effective time of the
         Employment Agreement, or any other action by the Employers which
         results in a diminution in such position, authority, duties or
         responsibilities excluding an isolated, insubstantial and inadvertent
         action not taken in bad faith and which is remedied by the Employers
         promptly after receipt of notice thereof given by the Employee;

                   (vii) the relocation of the Employee's office location as
         assigned to him by the Employers, to a location more than 25 miles from
         his office location at the effective time of the Employment Agreement;

                   (viii) any purported termination by the Employers of the
         Employee's employment otherwise than as expressly permitted by Section
         3(b) of this Agreement; and

                   (ix) any failure by the Employers to comply with and satisfy
         the provisions of Section 6 hereof, or failure by any successor
         (whether direct or indirect, by purchase, merger, consolidation or
         otherwise) to all or substantially all of the business and/or assets of
         the Employers to assume expressly and agree to perform the Employment
         Agreement in the same manner and to the same extent the Employers would
         be required to perform it if no such succession had taken place,
         provided, in either case, that the successor contemplated by Section 6
         hereof has received, at least 10 days prior to the giving of notice of
         constructive termination by the Employee, written notice from the
         Employers or the Employee of the requirements of the provisions of
         Section 6 or of such failure.

For purposes of this Agreement any good faith determination of "Constructive
Termination Without Cause" made by the Employee shall be conclusive.

         SECTION 4.  Compensation Following Termination.

          (a) Death or Disability. If the Employment Period is terminated
pursuant to the provisions of Section 3(a) above, this Agreement shall
terminate,





                                       4

<PAGE>   5



and no further compensation shall be payable to Employee except that Employee or
Employee's estate, heirs or beneficiaries, as applicable, shall be entitled, in
addition to any other benefits to which Employee is or may become entitled under
any benefit plan, to receive Employee's then current basic compensation, plus an
amount in lieu of bonus, which amount shall be determined as the average bonus
received by Employee for the appropriate period (prorated for partial portions
thereof) for the previous 24 months hereunder and all other benefits to which
Employee would otherwise be entitled hereunder during the Employment Period for
a period of 24 months from the date the Employment Period terminates.

          (b) Termination for Cause or Voluntary Termination. If the Employment
Period is terminated for Cause or voluntarily by the Employee for reasons other
than those described in Section 3(a) or 3(d) above, no further compensation or
benefits shall be paid to Employee after the date of termination, but Employee
shall be entitled to receive benefits to which he is or may become entitled
pursuant to any benefit plan.

          (c) Termination Without Cause; Constructive Termination. If the
Employment Period is terminated pursuant to Section 3(c) or 3(d) above, Employee
shall be entitled to continue to receive from Employers his then current basic
compensation hereunder, plus an amount in lieu of bonus, which amount shall be
determined as the average bonus received by Employee for the appropriate period
(prorated for partial portions thereof) for the previous 24 months, such amount
to continue to be paid in accordance with the payroll practices of Employers for
a period equal to the period remaining in the Employment Period immediately
prior to such termination and Employee shall further be entitled during such
period both to continue to receive the benefits to which he would otherwise be
entitled during the Employment Period pursuant to Section 2(c) above and to
reimbursement for expenses incurred by Employee to own and maintain an
automobile as contemplated by Section 5 below. Such continuation of
compensation, benefits and automobile expenses shall continue for the period
described above notwithstanding any earlier death or reemployment of Employee.

         SECTION 5. Expense Reimbursement. Upon the submission of properly
documented expense account reports, Employers shall reimburse Employee for all
reasonable business-related travel and entertainment expenses incurred by
Employee in the course of his Employment with Employers and for expenses
incurred by Employee to own and maintain an automobile.

         SECTION 6. Assignability; Binding Nature. This Agreement shall be
binding and inure to the benefit of the parties, and their respective
successors, heirs (in the case of Employee) and assigns. No obligations of the
Employers



                                       5


<PAGE>   6



under this Agreement may be assigned or transferred by the Employers except that
such obligations shall be assigned or transferred (as described below) pursuant
to a merger or consolidation of Holdings in which Holdings is not the continuing
entity, or the sale or liquidation of all or substantially all of the assets of
the Employers, provided that the assignee or transferee is the surviving entity
or successor to all or substantially all of the assets of the Employers and such
assignee or transferee assumes the liabilities, obligations and duties of the
Employers, as contained in this Agreement, either contractually or as a matter
of law. As used in this Agreement, the "Employers" and "Holdings" shall mean the
Employers and Holdings as hereinbefore defined, respectively, and any successor
to their business and/or assets as aforesaid which assumes and agrees to perform
this Agreement by operation of law, or otherwise.

         SECTION 7.  Confidential Information.

          (a) Non-Disclosure. During the Employment Period or at any time
thereafter, irrespective of the time, manner or cause of the termination of this
Agreement, Employee will not directly or indirectly reveal, divulge, disclose or
communicate to any person or entity, other than authorized officers, directors
and employees of the Employers, in any manner whatsoever, any Confidential
Information (as hereinafter defined) of Employers or any subsidiary of Employers
without the prior written consent of the Board.

          (b) Definition. As used herein, "CONFIDENTIAL INFORMATION" means
information disclosed to or known by Employee as a direct or indirect
consequence of or through the Employment about Employers or any subsidiary of
Employers, or their respective businesses, products and practices which
information is not generally known in the business in which Employers or any
subsidiary of Employers is or may be engaged. However, Confidential Information
shall not include under any circumstances any information with respect to the
foregoing matters which is (i) available to the public from a source other than
Employee, (ii) released in writing by Employers to the public or to persons who
are not under a similar obligation of confidentiality to Employers and who are
not parties to this Agreement, (iii) obtained by Employee from a third party not
under a similar obligation of confidentiality to Employers, (iv) required to be
disclosed by any court process or any government or agency or department of any
government, or (v) the subject of a written waiver executed by either Employers
for the benefit of Employee.

          (c) Return of Property. Upon termination of the Employment, Employee
will surrender to Employers all Confidential Information, including without
limitation, all lists, charts, schedules, reports, financial statements, books
and records of the Employers or any subsidiary of the Employers, and all copies




                                       6

thereof, and all other property belonging to the Employers or any subsidiary of
the Employers, provided Employee shall be accorded reasonable access to such
Confidential Information subsequent to the Employment Period for any proper
purpose as determined in the reasonable judgment of any of the Employers.

         SECTION 8. Agreement Not to Solicit Employees. Employee agrees that,
for a period of three (3) years following the termination of the Employment
Period, other than by Employers without Cause or as a result of the total
disability of Employee or by Employee as a constructive termination, and only by
reason of voluntary termination or termination for Cause, neither he nor any
affiliate shall, on behalf of any business engaged in a business competitive
with Employers or any subsidiary of Employers, solicit or induce, or in any
manner attempt to solicit or induce, any person employed by, or any agent of,
either of Employers or any subsidiary of Employers to terminate his employment
or agency, as the case may be, with either of Employers or such subsidiary;
provided that such limitations shall not apply if the contact with the Employee
or consultant is initiated by a third party on a "blind basis" such as through a
head hunter.

         SECTION 9. No Violation. Employee hereby represents and warrants to
Employers that the execution, delivery and performance of this Agreement by
Employee does not, with or without the giving of notice or the passage of time,
or both, conflict with, result in a default, right to accelerate or loss of
rights under any provision of any agreement or understanding to which the
Employee or, to the best knowledge of Employee, any of Employee's affiliates are
a party or by which Employee, or to the best knowledge of Employee, Employee's
affiliates may be bound or affected.

         SECTION 10.  Captions.  The captions, headings and arrangements used in

         SECTION 12. Invalid Provisions. If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws, such
provisions shall be fully severable, and this Agreement shall be construed and

exercise any right or power hereunder shall impair such right or power to be
construed as a waiver thereof. A waiver by any of the parties hereto of any of

covenant herein contained. Except as otherwise expressly set forth herein, all

         SECTION 17. Payment Upon Death of Employee. In the event of the death
of Employee during the term hereof, any unpaid payments due either prior to
Employee's death or after Employee's death shall be payable as designated by
Employee in writing to Employers. In the event of the death of all such persons
so designated by Employee, either prior to the death of the Employee or during
any time when payments are due as provided herein, or in the event Employee

                         EXECUTIVE EMPLOYMENT AGREEMENT

         This Agreement is made and entered into as of May 22, 1998 (the
EFFECTIVE DATE") by and among Thermadyne Holdings Corporation, a Delaware
corporation ("HOLDINGS"), together with its subsidiaries as herein defined (all
called the "EMPLOYERS") and Thomas C. Drury ("EMPLOYEE").

                                   WITNESSETH:

         WHEREAS, Employers desire to continue to employ Employee upon the
terms set forth herein;

         WHEREAS, Employee desires to continue to be employed by Employers and
to appropriately memorialize the terms and conditions of such employment;

         WHEREAS, Holdings is entering into this Agreement by and on behalf of
itself and each trade or business in which its ownership and the value or voting
power is at least 50% (the "SUBSIDIARIES");

         NOW THEREFORE, Employee and Employers, in consideration of the
agreements, covenants and conditions herein, hereby agree as follows:

         SECTION 1.  Basic Employment Provisions.

          (a) Employment and Term. Employers hereby employ Employee (hereinafter
referred to as the "EMPLOYMENT") as Vice President, Human Resources of Holdings
and Employee agrees to be employed by Employers in such capacity, all on the
terms and conditions set forth herein. The Employment shall be for a period (the
"EMPLOYMENT PERIOD") that will (i) commence on the Effective Date and continue
for at least three years thereafter (unless earlier terminated as provided
herein) and (ii) renew on each anniversary of the Effective Date for a
three-year period, on the same terms and conditions contained herein (unless
earlier terminated as provided herein or Employee is timely provided a notice of
nonrenewal as provided herein), such that the Employment Period shall extend for
a period of three years from the date of each such extension. The Employers must
provide Employee with written notice not less than 60 days in advance of the
applicable anniversary of the Effective Date in order to avoid renewal of the
Employment Period on such anniversary as described above. Notice shall be deemed
given on the date it is received by the Employee.

          (b) Duties. Employee shall be subject to the direction and supervision
of the Board of Directors of Holdings (the "BOARD") and, as the Vice President,
Human Resources of Holdings, shall have those duties and responsibilities which


<PAGE>   2

are assigned to him during the Employment Period by the Board consistent with
his positions, provided that the Board shall not assign any greater duties or
responsibilities to the Employee than are necessary to the Employee's faithful
and adequate supervision of the overall management and businesses of the
Employers. The Board shall not take any action which results in a diminution of
Employee's position, authority, duties or responsibilities as of the date
hereof. The parties expressly acknowledge that the Employee shall devote all of
his business time and attention to the transaction of the Employer's businesses
as is reasonably necessary to discharge his supervisory management
responsibilities hereunder. Employee agrees to perform faithfully the duties
assigned to him to the best of his ability.

         SECTION 2.  Compensation.

          (a) Salary. Employers shall pay to Employee during the Employment
Period a salary as basic compensation for the services to be rendered by
Employee hereunder. The initial amount of such salary shall be $145,000 per
annum. Such salary shall be reviewed no less frequently than annually by the
Board and may be increased upon the approval of the Board in its sole
discretion. Such salary shall accrue and be payable in accordance with the
payroll practices of Employers' subsidiary or subsidiaries in effect from time
to time. All such payments shall be subject to deduction and withholding
authorized or required by applicable law.

          (b) Bonus. During the Employment Period, Employee shall additionally
participate in an annual bonus plan providing for an annual bonus opportunity of
not less than 55% of Employee's annual salary.

          (c) Benefits. During the Employment Period, Employee shall be entitled
to participate in such other employee benefit plans, programs and arrangements
as are customarily accorded the executives of Employers, including without
limitation, tax qualified profit sharing and retirement plans, group life,
hospitalization and other insurance and vacations (but excluding stock option
and other stock- or equity-based compensation plans), on a basis no less
favorable than as of the date of this Agreement. Without limiting the foregoing,
the employee benefit plans, programs and arrangements in which Employee shall be
entitled to participate during the Employment Period shall be no less generous,
in the aggregate, than those in which such Employee was entitled to participate
immediately prior to the consummation of the merger between Holdings and Mercury
Acquisition Corporation.

         SECTION 3.  Termination.

          (a) Death or Disability. Employment of Employee under this Agreement
shall terminate automatically upon the death or total disability of Employee.
For the purpose of this Agreement, "TOTAL DISABILITY" shall be deemed to have
occurred if Employee shall have been unable to perform the duties of his
Employment due to mental or physical incapacity for a period of six (6)
consecutive months.

          (b) Cause. The Board may terminate the Employment of Employee under
this Agreement for Cause. For the purposes of this Agreement, "CAUSE" shall be
deemed to be (i) dishonesty by Employee that results in substantial personal
enrichment at the expense of the Employers or (ii) demonstratively willful
repeated violations of Employee's obligations under this Agreement which are
intended to result in material injury to the Employers.

          (c) Without Cause. Any of the Employers, acting alone, may terminate
the Employment of Employee under this Agreement without Cause.

          (d) Constructive Termination. Employee may elect to terminate his
Employment under this Agreement upon a Constructive Termination Without Cause,
as defined below. For purposes of this Agreement, "CONSTRUCTIVE TERMINATION
WITHOUT CAUSE" shall mean a termination of the Employee's employment at his
initiative following the occurrence, without the Employee's prior written
consent, of one or more of the following events:

                  (i) receipt of notice from the Employers that the Employment
         Period shall not be renewed as described in Section 1(a) above;

                  (ii) any failure by the Employers to comply with any of the
         provisions of the Employment Agreement, other than an isolated,
         insubstantial and inadvertent failure not occurring in bad faith and
         which is remedied by the Employers promptly after receipt of notice
         thereof given by the Employee;

                  (iii) any reduction in any form of compensation, fringe

                  (iv) the loss of any of the Employee's titles or positions in
         effect at the effective time of the Employment Agreement;

                  (v) any change in the position to which the Employee reports
         or the positions that report to the Employee at the effective time of
         the Employment Agreement (reporting relationships);

                  (vi) the assignment to the Employee of any duties inconsistent
         in any respect with the Employee's position (including status, offices,
         titles and reporting relationships), authority, duties or
         responsibilities as in effect at the effective time of the Employment
         Agreement, or any other action by the Employers which results in a
         diminution in such position, authority, duties or responsibilities
         excluding an isolated, insubstantial and inadvertent action not taken
         in bad faith and which is remedied by the Employers promptly after
         receipt of notice thereof given by the Employee;

                  (vii) the relocation of the Employee's office location as

         Employee's employment otherwise than as expressly permitted by Section
         3(b) of this Agreement; and

                  (ix) any failure by the Employers to comply with and satisfy
         the provisions of Section 6 hereof, or failure by any successor
         (whether direct or indirect, by purchase, merger, consolidation or
         otherwise) to all or substantially all of the business and/or assets of
         the Employers to assume expressly and agree to perform the Employment
         Agreement in the same manner and to the same extent the Employers would
         be required to perform it if no such succession had taken place,
         provided, in either case, that the successor contemplated by Section 6
         hereof has received, at least 10 days prior to the giving of notice of
         constructive termination by the Employee, written notice from the
         Employers or the Employee of the requirements of the provisions of
         Section 6 or of such failure.

For purposes of this Agreement any good faith determination of "Constructive
Termination Without Cause" made by the Employee shall be conclusive.

         SECTION 4.  Compensation Following Termination.

          (a) Death or Disability. If the Employment Period is terminated
pursuant to the provisions of Section 3(a) above, this Agreement shall
terminate,

                                       4

<PAGE>   5



and no further compensation shall be payable to Employee except that Employee or
Employee's estate, heirs or beneficiaries, as applicable, shall be entitled, in
addition to any other benefits to which Employee is or may become entitled under
any benefit plan, to receive Employee's then current basic compensation, plus an
amount in lieu of bonus, which amount shall be determined as the average bonus
received by Employee for the appropriate period (prorated for partial portions
thereof) for the previous 24 months hereunder and all other benefits to which
Employee would otherwise be entitled hereunder during the Employment Period for
a period of 24 months from the date the Employment Period terminates.

          (b) Termination for Cause or Voluntary Termination. If the Employment
Period is terminated for Cause or voluntarily by the Employee for reasons other
than those described in Section 3(a) or 3(d) above, no further compensation or
benefits shall be paid to Employee after the date of termination, but Employee
shall be entitled to receive benefits to which he is or may become entitled
pursuant to any benefit plan.

          (c) Termination Without Cause; Constructive Termination. If the
Employment Period is terminated pursuant to Section 3(c) or 3(d) above, Employee
shall be entitled to continue to receive from Employers his then current basic
compensation hereunder, plus an amount in lieu of bonus, which amount shall be
determined as the average bonus received by Employee for the appropriate period
(prorated for partial portions thereof) for the previous 24 months, such amount
to continue to be paid in accordance with the payroll practices of Employers for
a period equal to the period remaining in the Employment Period immediately
prior to such termination and Employee shall further be entitled during such
period both to continue to receive the benefits to which he would otherwise be
entitled during the Employment Period pursuant to Section 2(c) above and to
reimbursement for expenses incurred by Employee to own and maintain an
automobile as contemplated by Section 5 below. Such continuation of
compensation, benefits and automobile expenses shall continue for the period
described above notwithstanding any earlier death or reemployment of Employee.

         SECTION 5. Expense Reimbursement. Upon the submission of properly
documented expense account reports, Employers shall reimburse Employee for all
reasonable business-related travel and entertainment expenses incurred by
Employee in the course of his Employment with Employers and for expenses
incurred by Employee to own and maintain an automobile.

         SECTION 6. Assignability; Binding Nature. This Agreement shall be
binding and inure to the benefit of the parties, and their respective
successors, heirs (in the case of Employee) and assigns. No obligations of the
Employers

                                       5

<PAGE>   6



under this Agreement may be assigned or transferred by the Employers except that
such obligations shall be assigned or transferred (as described below) pursuant
to a merger or consolidation of Holdings in which Holdings is not the continuing
entity, or the sale or liquidation of all or substantially all of the assets of
the Employers, provided that the assignee or transferee is the surviving entity
or successor to all or substantially all of the assets of the Employers and such
assignee or transferee assumes the liabilities, obligations and duties of the
Employers, as contained in this Agreement, either contractually or as a matter
of law. As used in this Agreement, the "Employers" and "Holdings" shall mean the
Employers and Holdings as hereinbefore defined, respectively, and any successor
to their business and/or assets as aforesaid which assumes and agrees to perform
this Agreement by operation of law, or otherwise.

         SECTION 7.  Confidential Information.

          (a) Non-Disclosure. During the Employment Period or at any time
thereafter, irrespective of the time, manner or cause of the termination of this
Agreement, Employee will not directly or indirectly reveal, divulge, disclose or
communicate to any person or entity, other than authorized officers, directors
and employees of the Employers, in any manner whatsoever, any Confidential
Information (as hereinafter defined) of Employers or any subsidiary of Employers
without the prior written consent of the Board.

          (b) Definition. As used herein, "CONFIDENTIAL INFORMATION" means
information disclosed to or known by Employee as a direct or indirect
consequence of or through the Employment about Employers or any subsidiary of
Employers, or their respective businesses, products and practices which
information is not generally known in the business in which Employers or any
subsidiary of Employers is or may be engaged. However, Confidential Information
shall not include under any circumstances any information with respect to the
foregoing matters which is (i) available to the public from a source other than
Employee, (ii) released in writing by Employers to the public or to persons who
are not under a similar obligation of confidentiality to Employers and who are
not parties to this Agreement, (iii) obtained by Employee from a third party not
under a similar obligation of confidentiality to Employers, (iv) required to be
disclosed by any court process or any government or agency or department of any
government, or (v) the subject of a written waiver executed by either Employers
for the benefit of Employee.

          (c) Return of Property. Upon termination of the Employment, Employee
will surrender to Employers all Confidential Information, including without
limitation, all lists, charts, schedules, reports, financial statements, books
and records of the Employers or any subsidiary of the Employers, and all copies

                                       6

<PAGE>   7



thereof, and all other property belonging to the Employers or any subsidiary of
the Employers, provided Employee shall be accorded reasonable access to such
Confidential Information subsequent to the Employment Period for any proper
purpose as determined in the reasonable judgment of any of the Employers.

         SECTION 8. Agreement Not to Solicit Employees. Employee agrees that,
for a period of three (3) years following the termination of the Employment
Period, other than by Employers without Cause or as a result of the total
disability of Employee or by Employee as a constructive termination, and only by
reason of voluntary termination or termination for Cause, neither he nor any
affiliate shall, on behalf of any business engaged in a business competitive
with Employers or any subsidiary of Employers, solicit or induce, or in any
manner attempt to solicit or induce, any person employed by, or any agent of,
either of Employers or any subsidiary of Employers to terminate his employment
or agency, as the case may be, with either of Employers or such subsidiary;
provided that such limitations shall not apply if the contact with the Employee
or consultant is initiated by a third party on a "blind basis" such as through a
head hunter.

         SECTION 9. No Violation. Employee hereby represents and warrants to
Employers that the execution, delivery and performance of this Agreement by
Employee does not, with or without the giving of notice or the passage of time,
or both, conflict with, result in a default, right to accelerate or loss of
rights under any provision of any agreement or understanding to which the
Employee or, to the best knowledge of Employee, any of Employee's affiliates are
a party or by which Employee, or to the best knowledge of Employee, Employee's
affiliates may be bound or affected.

         SECTION 10.  Captions.  The captions, headings and arrangements used in
this Agreement are for convenience only and do not in any way affect, limit or
amplify the provisions hereof.

actually received, two days after deposited in the United States mail, postage
prepaid, registered or certified mail, return receipt requested, addressed to

         SECTION 12. Invalid Provisions. If any provision of this Agreement is
held to be illegal, invalid or unenforceable under present or future laws, such
provisions shall be fully severable, and this Agreement shall be construed and
enforced as if such illegal, invalid or unenforceable provision had never
comprised a part of this Agreement; the remaining provisions of this Agreement
shall remain in full force and effect and shall not be affected by the illegal,

         SECTION 14. Waiver. No delay or omission by any party hereto to
exercise any right or power hereunder shall impair such right or power to be
construed as a waiver thereof. A waiver by any of the parties hereto of any of
the covenants to be performed by any other party or any breach thereof shall not
be construed to be a waiver of any succeeding breach thereof or of any other

                                       8

covenant herein contained. Except as otherwise expressly set forth herein, all

and not in lieu of any other remedies available to any party at law, in equity
or otherwise.

         SECTION 15. Counterparts. This Agreement may be executed in multiple

together shall constitute one and the same Agreement.

         SECTION 16.  Governing Law.  This Agreement shall be construed and
enforced according to the laws of the State of Missouri.

         SECTION 17. Payment Upon Death of Employee. In the event of the death
of Employee during the term hereof, any unpaid payments due either prior to
Employee's death or after Employee's death shall be payable as designated by
Employee in writing to Employers. In the event of the death of all such persons
so designated by Employee, either prior to the death of the Employee or during
any time when payments are due as provided herein, or in the event Employee
fails to so designate, or withdraws all such designations, said payments
thereafter shall be made to the Employee or to Employee's estate.

         SECTION 18.  Prior Employment Agreement.  This Agreement supersedes

                         EXECUTIVE EMPLOYMENT AGREEMENT

         This Agreement is made and entered into as of May 22, 1998, (the
EFFECTIVE DATE") by and among Thermadyne Holdings Corporation, a Delaware
corporation ("HOLDINGS"), together with its subsidiaries as herein defined (all
called the "EMPLOYERS") and Robert D. Maddox ("EMPLOYEE").

                                   WITNESSETH:

         WHEREAS, Employers desire to continue to employ Employee upon the
terms set forth herein;

         WHEREAS, Employee desires to continue to be employed by Employers and
to appropriately memorialize the terms and conditions of such employment;

         WHEREAS, Holdings is entering into this Agreement by and on behalf of
itself and each trade or business in which its ownership and the value or voting
power is at least 50% (the "SUBSIDIARIES");

         NOW THEREFORE, Employee and Employers, in consideration of the
agreements, covenants and conditions herein, hereby agree as follows:

         SECTION 1.  Basic Employment Provisions.

          (a) Employment and Term. Employers hereby employ Employee (hereinafter
referred to as the "EMPLOYMENT") as Vice President and Controller of Holdings
and Employee agrees to be employed by Employers in such capacities, all on the
terms and conditions set forth herein. The Employment shall be for a period (the
"EMPLOYMENT PERIOD") that will (i) commence on the Effective Date and continue
for at least three years thereafter (unless earlier terminated as provided
herein) and (ii) renew on each anniversary of the Effective Date for a
three-year period, on the same terms and conditions contained herein (unless
earlier terminated as provided herein or Employee is timely provided a notice of
nonrenewal as provided herein), such that the Employment Period shall extend for
a period of three years from the date of each such extension. The Employers must
provide Employee with written notice not less than 60 days in advance of the
applicable anniversary of the Effective Date in order to avoid renewal of the
Employment Period on such anniversary as described above. Notice shall be deemed
given on the date it is received by the Employee.

          (b) Duties. Employee shall be subject to the direction and supervision
of the Board of Directors of Holdings (the "BOARD") and, as the Vice President
and Controller of Holdings, shall have those duties and responsibilities which
are



<PAGE>   2



assigned to him during the Employment Period by the Board consistent with his
positions, provided that the Board shall not assign any greater duties or
responsibilities to the Employee than are necessary to the Employee's faithful
and adequate supervision of the overall management and businesses of the
Employers. The Board shall not take any action which results in a diminution of
Employee's position, authority, duties or responsibilities as of the date
hereof. The parties expressly acknowledge that the Employee shall devote all of
his business time and attention to the transaction of the Employer's businesses
as is reasonably necessary to discharge his supervisory management
responsibilities hereunder. Employee agrees to perform faithfully the duties
assigned to him to the best of his ability.

         SECTION 2.  Compensation.

          (a) Salary. Employers shall pay to Employee during the Employment
Period a salary as basic compensation for the services to be rendered by
Employee hereunder. The initial amount of such salary shall be $145,000 per
annum. Such salary shall be reviewed no less frequently than annually by the
Board and may be increased upon the approval of the Board in its sole
discretion. Such salary shall accrue and be payable in accordance with the
payroll practices of Employers' subsidiary or subsidiaries in effect from time
to time. All such payments shall be subject to deduction and withholding
authorized or required by applicable law.

          (b) Bonus. During the Employment Period, Employee shall additionally
participate in an annual bonus plan providing for an annual bonus opportunity of
not less than 55% of Employee's annual salary.

          (c) Benefits. During the Employment Period, Employee shall be entitled
to participate in such other employee benefit plans, programs and arrangements
as are customarily accorded the executives of Employers, including without
limitation, tax qualified profit sharing and retirement plans, group life,
hospitalization and other insurance and vacations (but excluding stock option
and other stock- or equity-based compensation plans), on a basis no less
favorable than as of the date of this Agreement. Without limiting the foregoing,
the employee benefit plans, programs and arrangements in which Employee shall be
entitled to participate during the Employment Period shall be no less generous,
in the aggregate, than those in which such Employee was entitled to participate
immediately prior to the consummation of the merger between Holdings and Mercury
Acquisition Corporation.

         SECTION 3.  Termination.

          (a) Death or Disability. Employment of Employee under this Agreement
shall terminate automatically upon the death or total disability of Employee.
For the purpose of this Agreement, "TOTAL DISABILITY" shall be deemed to have
occurred if Employee shall have been unable to perform the duties of his
Employment due to mental or physical incapacity for a period of six (6)
consecutive months.

          (b) Cause. The Board may terminate the Employment of Employee under
this Agreement for Cause. For the purposes of this Agreement, "CAUSE" shall be
deemed to be (i) dishonesty by Employee that results in substantial personal
enrichment at the expense of the Employers or (ii) demonstratively willful
repeated violations of Employee's obligations under this Agreement which are
intended to result in material injury to the Employers.

          (c) Without Cause. Any of the Employers, acting alone, may terminate
the Employment of Employee under this Agreement without Cause.

          (d) Constructive Termination. Employee may elect to terminate his
Employment under this Agreement upon a Constructive Termination Without Cause,
as defined below. For purposes of this Agreement, "CONSTRUCTIVE TERMINATION
WITHOUT CAUSE" shall mean a termination of the Employee's employment at his
initiative following the occurrence, without the Employee's prior written
consent, of one or more of the following events:

                  (i) receipt of notice from the Employers that the Employment
         Period shall not be renewed as described in Section 1(a) above;

                  (ii) any failure by the Employers to comply with any of the
         provisions of the Employment Agreement, other than an isolated,
         insubstantial and inadvertent failure not occurring in bad faith and
         which is remedied by the Employers promptly after receipt of notice
         thereof given by the Employee;

                  (iii) any reduction in any form of compensation, fringe
         benefit, deferred compensation plan or perquisite applicable to the
         Employee immediately prior to the effective time of the Employment
         Agreement, including any reduction in salary or any reduction in bonus
         percentage to less than the average of such bonus percentage for the
         two fiscal years immediately preceding the effective time of the
         Employment Agreement;

                                       3

<PAGE>   4



                  (iv) the loss of any of the Employee's titles or positions in
         effect at the effective time of the Employment Agreement;

                  (v) any change in the position to which the Employee reports
         or the positions that report to the Employee at the effective time of
         the Employment Agreement (reporting relationships);

                  (vi) the assignment to the Employee of any duties inconsistent
         in any respect with the Employee's position (including status, offices,
         titles and reporting relationships), authority, duties or
         responsibilities as in effect at the effective time of the Employment
         Agreement, or any other action by the Employers which results in a
         diminution in such position, authority, duties or responsibilities
         excluding an isolated, insubstantial and inadvertent action not taken
         in bad faith and which is remedied by the Employers promptly after
         receipt of notice thereof given by the Employee;

                  (vii) the relocation of the Employee's office location as
         assigned to him by the Employers, to a location more than 25 miles from
         his office location at the effective time of the Employment Agreement;

                  (viii) any purported termination by the Employers of the
         Employee's employment otherwise than as expressly permitted by Section
         3(b) of this Agreement; and

                  (ix) any failure by the Employers to comply with and satisfy
         the provisions of Section 6 hereof, or failure by any successor
         (whether direct or indirect, by purchase, merger, consolidation or
         otherwise) to all or substantially all of the business and/or assets of
         the Employers to assume expressly and agree to perform the Employment
         Agreement in the same manner and to the same extent the Employers would
         be required to perform it if no such succession had taken place,
         provided, in either case, that the successor contemplated by Section 6
         hereof has received, at least 10 days prior to the giving of notice of
         constructive termination by the Employee, written notice from the
         Employers or the Employee of the requirements of the provisions of
         Section 6 or of such failure.

For purposes of this Agreement any good faith determination of "Constructive
Termination Without Cause" made by the Employee shall be conclusive.

         SECTION 4.  Compensation Following Termination.

          (a) Death or Disability. If the Employment Period is terminated
pursuant to the provisions of Section 3(a) above, this Agreement shall
terminate,

                                       4

<PAGE>   5



and no further compensation shall be payable to Employee except that Employee or
Employee's estate, heirs or beneficiaries, as applicable, shall be entitled, in
addition to any other benefits to which Employee is or may become entitled under
any benefit plan, to receive Employee's then current basic compensation, plus an
amount in lieu of bonus, which amount shall be determined as the average bonus
received by Employee for the appropriate period (prorated for partial portions
thereof) for the previous 24 months hereunder and all other benefits to which
Employee would otherwise be entitled hereunder during the Employment Period for
a period of 24 months from the date the Employment Period terminates.

          (b) Termination for Cause or Voluntary Termination. If the Employment
Period is terminated for Cause or voluntarily by the Employee for reasons other
than those described in Section 3(a) or 3(d) above, no further compensation or
benefits shall be paid to Employee after the date of termination, but Employee
shall be entitled to receive benefits to which he is or may become entitled
pursuant to any benefit plan.

          (c) Termination Without Cause; Constructive Termination. If the
Employment Period is terminated pursuant to Section 3(c) or 3(d) above, Employee
shall be entitled to continue to receive from Employers his then current basic
compensation hereunder, plus an amount in lieu of bonus, which amount shall be
determined as the average bonus received by Employee for the appropriate period
(prorated for partial portions thereof) for the previous 24 months, such amount
to continue to be paid in accordance with the payroll practices of Employers for
a period equal to the period remaining in the Employment Period immediately
prior to such termination and Employee shall further be entitled during such
period both to continue to receive the benefits to which he would otherwise be
entitled during the Employment Period pursuant to Section 2(c) above and to
reimbursement for expenses incurred by Employee to own and maintain an
automobile as contemplated by Section 5 below. Such continuation of
compensation, benefits and automobile expenses shall continue for the period
described above notwithstanding any earlier death or reemployment of Employee.

         SECTION 5. Expense Reimbursement. Upon the submission of properly
documented expense account reports, Employers shall reimburse Employee for all
reasonable business-related travel and entertainment expenses incurred by
Employee in the course of his Employment with Employers and for expenses
incurred by Employee to own and maintain an automobile.

         SECTION 6. Assignability; Binding Nature. This Agreement shall be
binding and inure to the benefit of the parties, and their respective
successors, heirs (in the case of Employee) and assigns. No obligations of the
Employers

under this Agreement may be assigned or transferred by the Employers except that
such obligations shall be assigned or transferred (as described below) pursuant

the Employers, provided that the assignee or transferee is the surviving entity
or successor to all or substantially all of the assets of the Employers and such

         SECTION 7.  Confidential Information.

          (a) Non-Disclosure. During the Employment Period or at any time

without the prior written consent of the Board.

          (b) Definition. As used herein, "CONFIDENTIAL INFORMATION" means

consequence of or through the Employment about Employers or any subsidiary of
Employers, or their respective businesses, products and practices which
information is not generally known in the business in which Employers or any
subsidiary of Employers is or may be engaged. However, Confidential Information
shall not include under any circumstances any information with respect to the
foregoing matters which is (i) available to the public from a source other than
Employee, (ii) released in writing by Employers to the public or to persons who
are not under a similar obligation of confidentiality to Employers and who are
not parties to this Agreement, (iii) obtained by Employee from a third party not
under a similar obligation of confidentiality to Employers, (iv) required to be
disclosed by any court process or any government or agency or department of any
government, or (v) the subject of a written waiver executed by either Employers

the Employers, provided Employee shall be accorded reasonable access to such
Confidential Information subsequent to the Employment Period for any proper
purpose as determined in the reasonable judgment of any of the Employers.

         SECTION 8. Agreement Not to Solicit Employees. Employee agrees that,
for a period of three (3) years following the termination of the Employment
Period, other than by Employers without Cause or as a result of the total
disability of Employee or by Employee as a constructive termination, and only by
reason of voluntary termination or termination for Cause, neither he nor any
affiliate shall, on behalf of any business engaged in a business competitive
with Employers or any subsidiary of Employers, solicit or induce, or in any
manner attempt to solicit or induce, any person employed by, or any agent of,
either of Employers or any subsidiary of Employers to terminate his employment
or agency, as the case may be, with either of Employers or such subsidiary;
provided that such limitations shall not apply if the contact with the Employee
or consultant is initiated by a third party on a "blind basis" such as through a
head hunter.

         SECTION 9. No Violation. Employee hereby represents and warrants to
Employers that the execution, delivery and performance of this Agreement by
Employee does not, with or without the giving of notice or the passage of time,
or both, conflict with, result in a default, right to accelerate or loss of
rights under any provision of any agreement or understanding to which the
Employee or, to the best knowledge of Employee, any of Employee's affiliates are
a party or by which Employee, or to the best knowledge of Employee, Employee's

covenant herein contained. Except as otherwise expressly set forth herein, all

         Thermadyne Holdings Corporation, a Delaware corporation (the
"COMPANY"), hereby grants to the above-named optionee (the "OPTIONEE") a time
vesting option (the "TIME VESTING OPTION") and a cliff vesting option (the
"CLIFF VESTING OPTION" and, together with the Time Vesting Option, the
"OPTIONS") to purchase from the Company, for the price per share set forth
above, the number of shares of Common Stock, $0.01 par value (the "SHARES"), of
the Company set forth above pursuant to the Thermadyne Holdings Corporation
Management Incentive Plan (the "PLAN"). The Options are not intended to be
treated as incentive stock options under the Code.

         Capitalized terms not otherwise defined herein shall have the same
meanings as in the Plan. The terms and conditions of the Option granted hereby,
to the extent not controlled by the terms and conditions contained in the Plan,
are as follows:

         1.        Exercise Price.  The price at which each Share subject to 
this Option may be purchased shall be the price set forth above.

         2.        Number of Shares; Exercise. The number of Shares for which 
the Time Vesting Option and the Cliff Vesting Option may be exercised are set
forth above. To the extent this Option has become vested in accordance with
Sections 3 and 4 below, the Option may be exercised at any time until the

                                                                          Page 2




         3.       Vesting: Time Vesting Option. As of the Date of Grant, the
Time Vesting Option shall become vested and exercisable with respect to 20% of
the Shares subject thereto. On each of the first five anniversaries of the Date
of Grant, provided the Optionee is then in the employ of the Company or a
Subsidiary, the Time Vesting Option shall become vested and exercisable with
respect to an additional 16% of the Shares subject thereto.

         4.       Vesting:  Cliff Vesting Option.

         (a)      To the extent not previously vested in accordance with 
paragraph (b) or (c) below, the Cliff Vesting Option shall become fully vested
and exercisable on the eighth anniversary of the Date of Grant, provided the
Optionee is then in the employ of the Company or a Subsidiary.

         (b)      The Cliff Vesting Option shall become vested and exercisable
with respect to 20% of the Shares subject thereto on the thirtieth day following
the availability of audited financial statements for each of the five fiscal
years of the Company commencing with the fiscal year ending December 31, 1998
(each such day a "CLIFF VESTING DATE"), provided the implied common equity value
of the Company as of the end of such fiscal year, calculated in accordance with
Exhibit A hereto, is at least equal to the target value for such fiscal year set
forth in such Exhibit A, and provided further that the Optionee is in the employ
of the Company or a Subsidiary on such Cliff Vesting Date. If the target set
forth in Exhibit A for any of the first four fiscal years referred to above is
not attained, the portion of the Cliff Vesting Option that would otherwise have
vested for such fiscal year shall be treated as vested and exercisable as of the
Cliff Vesting Date for any subsequent fiscal year ending on or before December
31, 2002 for which the target for such subsequent year is attained, provided the
Optionee is in the employ of the Company or a Subsidiary on such Cliff Vesting
Date.

         (c)      Upon the occurrence of a Liquidation Event, provided the DLJ
Entities' realized annual investment rate of return as calculated in accordance
with Exhibit B ("DLJ IRR") is at least 20%, and provided the Optionee is in the
employ of the Company or a Subsidiary as of such Liquidation Event, the Cliff
Vesting Option shall become vested and exercisable with respect to a portion of
the Shares subject thereto as to which the Option has not yet vested in
accordance with paragraph (b) above ("UNVESTED CLIFF VESTING SHARES"). In such
case, the Cliff Vesting Option will become vested and exercisable with respect
to the applicable percentage of the Unvested Cliff Vesting Shares set forth in
Exhibit B hereto, based on the DLJ IRR.

         5.       Manner of Exercise. The Optionee (or his representative, 
devisee or heir, as applicable) may exercise any portion of this Option which
has become exercisable in accordance with the terms hereof as to all or any of
the Shares then available for purchase by delivering to the Company written
notice specifying:

                                                                          Page 3



                  (i)      the number of whole Shares to be purchased together 
         with payment in full of the aggregate Exercise Price of such shares;

                  (ii)     the address to which dividends, notices, reports, 
         etc. are to be sent; and

                  (iii)    the Optionee's social security number.

Payment shall be in cash, by certified or bank cashier's check payable to the
order of the Company, free from all collection charges, or in unencumbered
Shares (provided such shares shall have been held by the Optionee for at least
six months unless the Committee determines in its sole discretion that such
six-month holding period is not necessary to comply with any accounting, legal
or regulatory requirement) having a Fair Market Value equal to the full amount
of the Exercise Price therefor, or such other form as may be permitted by the
Committee. Only one stock certificate will be issued unless the Optionee
otherwise requests in writing. Shares purchased upon exercise of the Option will
be issued in the name of the Optionee or the Optionee's Permitted Transferee.
The Optionee shall not be entitled to any rights as a stockholder of the Company
in respect of any Shares covered by this Option until such Shares shall have
been paid for in full and issued to the Optionee.

         6.       Certificates. Certificates issued in respect of Shares
acquired upon exercise of the Option shall, unless the Committee otherwise
determines, be registered in the name of the Optionee or its Permitted
Transferee. When the Optionee ceases to be bound by the provisions of the
Investors' Agreement, the Company shall deliver such certificates to the
Optionee or its Permitted Transferee upon request. Such stock certificate shall
carry such appropriate legends, and such written instructions shall be given to
the Company's transfer agent, as may be deemed necessary or advisable by counsel
to the Company in order to comply with the requirements of the Securities Act of
1933, any state securities laws or any other applicable laws or the Investors'
Agreement.

         7.       Nontransferability. This Option is personal to the Optionee
and may be exercised only by the Optionee or his or her representative in the
event of the Optionee's Disability or death. This Option shall not be
transferable other than by will or the laws of descent and distribution.
Notwithstanding the foregoing, this Option may be transferred to a trust solely
for the benefit of the Optionee or the Optionee's immediate family (which shall
be deemed to include the Optionee's spouse, parents, siblings, children,
stepchildren and grandchildren).

         8.        Forfeiture of Option; Right of Repurchase.

         (a)      If the Optionee's employment with the Company and its
Subsidiaries shall terminate for any reason other than by the Company or its
Subsidiary for Cause, then (i) to the extent not yet vested as of the date of
termination of employment, the Option shall immediately be forfeited; and (ii)
to the extent vested as of the date of termination of employment, the Option may
be retained and exercised, in accordance with the terms of the Plan and this
Award Agreement, until the Expiration Date.

         (b)      If the Optionee's employment with the Company and its
Subsidiaries shall be terminated by the Company or its Subsidiary for Cause,
then the entire Option shall immediately be forfeited, and all Shares previously
acquired upon exercise of the Option shall be subject to a right of repurchase
by the Company from the Participant or his or her Permitted Transferee at a
price equal to the Exercise Price.

         9.       Change of Control. Upon a Change of Control, the Time Vesting
Option shall vest in its entirety and become immediately exercisable and, if the
Change of Control constitutes a Liquidation Event, the Cliff Vesting Option
shall vest in accordance with Section 4(c) hereof.

         10.      Sale of Underlying Shares. The Optionee's right to sell any
Shares acquired upon exercise of the Option (in the case of Optionees who are
party thereto) shall be subject to the terms of the Investors' Agreement.

         11.      Employment Rights. This Option does not confer on the Optionee
any right to continue in the employ of the Company or any Subsidiary or
interfere in any way with the right of the Company or any Subsidiary to
determine the terms of the Optionee's employment.

         12.      Terms of Plan; Interpretations. This Option and the terms and
conditions herein set forth are subject in all respects to the terms and
conditions of the Plan, which shall be controlling. All interpretations or
determinations of the Committee and/or the Board shall be binding and conclusive
upon the Optionee and his legal representatives on any question arising
hereunder. The Optionee acknowledges that he has received and reviewed a copy of
the Plan.

to the extent not controlled by the terms and conditions contained in the Plan,

Vesting Option and the Cliff Vesting Option may be exercised are set forth

         3. Vesting: Time Vesting Option. As of the Date of Grant, the Time
Vesting Option shall become vested and exercisable with respect to 20% of the
Shares subject thereto. On each of the first five anniversaries of the Date of
Grant, provided the Optionee is then in the employ of the Company or a
Subsidiary, the Time Vesting Option shall become vested and exercisable with
respect to an additional 16% of the Shares subject thereto.

         4. Vesting: Cliff Vesting Option.

         (a) To the extent not previously vested in accordance with paragraph
(b) or (c) below, the Cliff Vesting Option shall become fully vested and
exercisable on the eighth anniversary of the Date of Grant, provided the
Optionee is then in the employ of the Company or a Subsidiary.

         (b) The Cliff Vesting Option shall become vested and exercisable with
respect to 20% of the Shares subject thereto on the thirtieth day following the
availability of audited financial statements for each of the five fiscal years
of the Company commencing with the fiscal year ending December 31, 1998 (each
such day a "CLIFF VESTING DATE"), provided the implied common equity value of
the Company as of the end of such fiscal year, calculated in accordance with
Exhibit A hereto, is at least equal to the target value for such fiscal year set
forth in such Exhibit A, and provided further that the Optionee is in the employ
of the Company or a Subsidiary on such Cliff Vesting Date. If the target set
forth in Exhibit A for any of the first four fiscal years referred to above is
not attained, the portion of the Cliff Vesting Option that would otherwise have
vested for such fiscal year shall be treated as vested and exercisable as of the
Cliff Vesting Date for any subsequent fiscal year ending on or before December
31, 2002 for which the target for such subsequent year is attained, provided the
Optionee is in the employ of the Company or a Subsidiary on such Cliff Vesting
Date.

         (c) Upon the occurrence of a Liquidation Event, provided the DLJ
Entities' realized annual investment rate of return as calculated in accordance
with Exhibit B ("DLJ IRR") is at least 20%, and provided the Optionee is in the
employ of the Company or a Subsidiary as of such Liquidation Event, the Cliff
Vesting Option shall become vested and exercisable with respect to a portion of
the Shares subject thereto as to which the Option has not yet vested in
accordance with paragraph (b) above ("UNVESTED CLIFF VESTING SHARES"). In such
case, the Cliff Vesting Option will become vested and exercisable with respect
to the applicable percentage of the Unvested Cliff Vesting Shares set forth in
Exhibit B hereto, based on the DLJ IRR.

         5. Manner of Exercise. The Optionee (or his representative, devisee or
heir, as applicable) may exercise any portion of this Option which has become
exercisable in accordance with the terms hereof as to all or any of the Shares

                                                                          Page 3

                  (i) the number of whole Shares to be purchased together with
         payment in full of the aggregate Exercise Price of such shares;

                  (ii) the address to which dividends, notices, reports, etc.

Payment shall be in cash, by certified or bank cashier's check payable to the
order of the Company, free from all collection charges, or in unencumbered
Shares (provided such shares shall have been held by the Optionee for at least
six months unless the Committee determines in its sole discretion that such
six-month holding period is not necessary to comply with any accounting, legal
or regulatory requirement) having a Fair Market Value equal to the full amount
of the Exercise Price therefor, or such other form as may be permitted by the
Committee. Only one stock certificate will be issued unless the Optionee
otherwise requests in writing. Shares purchased upon exercise of the Option will
be issued in the name of the Optionee or the Optionee's Permitted Transferee.
The Optionee shall not be entitled to any rights as a stockholder of the Company
in respect of any Shares covered by this Option until such Shares shall have
been paid for in full and issued to the Optionee.

         6. Certificates. Certificates issued in respect of Shares acquired upon
exercise of the Option shall, unless the Committee otherwise determines, be
registered in the name of the Optionee or its Permitted Transferee. When the
Optionee ceases to be bound by the provisions of the Investors' Agreement, the
Company shall deliver such certificates to the Optionee or its Permitted
Transferee upon request. Such stock certificate shall carry such appropriate
legends, and such written instructions shall be given to the Company's transfer
agent, as may be deemed necessary or advisable by counsel to the Company in
order to comply with the requirements of the Securities Act of 1933, any state
securities laws or any other applicable laws or the Investors' Agreement.

         7. Nontransferability. This Option is personal to the Optionee and may
be exercised only by the Optionee or his or her representative in the event of
the Optionee's Disability or death. This Option shall not be transferable other
than by will or the laws of descent and distribution. Notwithstanding the
foregoing, this Option may be transferred to a trust solely for the benefit of
the Optionee or the Optionee's immediate family (which shall be deemed to
include the Optionee's spouse, parents, siblings, children, stepchildren and
grandchildren).

         8.        Forfeiture of Option; Right of Repurchase.

         (a) If the Optionee's employment with the Company and its Subsidiaries
shall terminate for any reason other than by the Company or its Subsidiary for
Cause, then (i) to the extent not yet vested as of the date of termination of
employment, the Option shall immediately be forfeited; and (ii) to the extent
vested as of the date of termination of employment, the Option may be retained
and exercised, in accordance with the terms of the Plan and this Award
Agreement, until the Expiration Date.

         (b) If the Optionee's employment with the Company and its Subsidiaries
shall be terminated by the Company or its Subsidiary for Cause, then the entire
Option shall immediately be forfeited, and all Shares previously acquired upon
exercise of the Option shall be subject to a right of repurchase by the Company
from the Participant or his or her Permitted Transferee at a price equal to the
Exercise Price.

         9. Change of Control. Upon a Change of Control, the Time Vesting Option
shall vest in its entirety and become immediately exercisable and, if the Change
of Control constitutes a Liquidation Event, the Cliff Vesting Option shall vest
in accordance with Section 4(c) hereof.

         10. Sale of Underlying Shares. The Optionee's right to sell any Shares
acquired upon exercise of the Option (in the case of Optionees who are party
thereto) shall be subject to the terms of the Investors' Agreement.

         11. Employment Rights. This Option does not confer on the Optionee any
right to continue in the employ of the Company or any Subsidiary or interfere in
any way with the right of the Company or any Subsidiary to determine the terms
of the Optionee's employment.

         12. Terms of Plan; Interpretations. This Option and the terms and
conditions herein set forth are subject in all respects to the terms and
conditions of the Plan, which shall be controlling. All interpretations or
determinations of the Committee and/or the Board shall be binding and conclusive

six-month holding period is not necessary to comply with any accounting, legal
or regulatory requirement) having a Fair Market Value equal to the full amount
of the Exercise Price therefor, or such other form as may be permitted by the

Transferee upon request. Such stock certificate shall carry such appropriate
legends, and such written instructions shall be given to the Company's transfer
agent, as may be deemed necessary or advisable by counsel to the Company in
order to comply with the requirements of the Securities Act of 1933, any state
securities laws or any other applicable laws or the Investors' Agreement.

         7. Nontransferability. This Option is personal to the Optionee and may
be exercised only by the Optionee or his or her representative in the event of
the Optionee's Disability or death. This Option shall not be transferable other
than by will or the laws of descent and distribution. Notwithstanding the
foregoing, this Option may be transferred to a trust solely for the benefit of
the Optionee or the Optionee's immediate family (which shall be deemed to
include the Optionee's spouse, parents, siblings, children, stepchildren and
grandchildren).

         (a) If the Optionee's employment with the Company and its Subsidiaries

Cause, then (i) to the extent not yet vested as of the date of termination of
employment, the Option shall immediately be forfeited; and (ii) to the extent

Option shall immediately be forfeited, and all Shares previously acquired upon
exercise of the Option shall be subject to a right of repurchase by the Company
from the Participant or his or her Permitted Transferee at a price equal to the
Exercise Price.

         9. Change of Control. Upon a Change of Control, the Time Vesting Option

acquired upon exercise of the Option (in the case of Optionees who are party
thereto) shall be subject to the terms of the Investors' Agreement.

         11. Employment Rights. This Option does not confer on the Optionee any
right to continue in the employ of the Company or any Subsidiary or interfere in
any way with the right of the Company or any Subsidiary to determine the terms
of the Optionee's employment.

         12. Terms of Plan; Interpretations. This Option and the terms and
conditions herein set forth are subject in all respects to the terms and

         Thermadyne Holdings Corporation, a Delaware corporation (the
"COMPANY"), hereby grants to the above-named optionee (the "OPTIONEE") a time
vesting option (the "TIME VESTING OPTION") and a cliff vesting option (the
"CLIFF VESTING OPTION" and, together with the Time Vesting Option, the
"OPTIONS") to purchase from the Company, for the price per share set forth
above, the number of shares of Common Stock, $0.01 par value (the "SHARES"), of
the Company set forth above pursuant to the Thermadyne Holdings Corporation
Management Incentive Plan (the "PLAN").  The Options are not intended to be
treated as incentive stock options under the Code.

         Capitalized terms not otherwise defined herein shall have the same
meanings as in the Plan.  The terms and conditions of the Option granted
hereby, to the extent not controlled by the terms and conditions contained in
the Plan, are as follows:

         1.      Exercise Price.  The price at which each Share subject to
this Option may be purchased shall be the price set forth above.

         2.      Number of Shares; Exercise.  The number of Shares for which
the Time Vesting Option and the Cliff Vesting Option may be exercised are set
forth above.  To the extent this Option has become vested in accordance with
Sections 3 and 4 below, the Option may be exercised at any time until the
Expiration Date, subject to the terms of the Plan and of Section 8 below.

                                                                         Page 2


         3.      Vesting:  Time Vesting Option.  As of the Date of Grant, the
Time Vesting Option shall become vested and exercisable with respect to 20% of
the Shares subject thereto.  On each of the first five anniversaries of the
Date of Grant, provided the Optionee is then in the employ of the Company or a
Subsidiary, the Time Vesting Option shall become vested and exercisable with
respect to an additional 16% of the Shares subject thereto.

         4.      Vesting:  Cliff Vesting Option.

         (a)     To the extent not previously vested in accordance with
paragraph (b) or (c) below, the Cliff Vesting Option shall become fully vested
and exercisable on the eighth anniversary of the Date of Grant, provided the
Optionee is then in the employ of the Company or a Subsidiary.

         (b)     The Cliff Vesting Option shall become vested and exercisable
with respect to 20% of the Shares subject thereto on the thirtieth day
following the availability of audited financial statements for each of the five
fiscal years of the Company commencing with the fiscal year ending December 31,
1998 (each such day a "CLIFF VESTING DATE"), provided the implied common equity
value of the Company as of the end of such fiscal year, calculated in
accordance with Exhibit A hereto, is at least equal to the target value for
such fiscal year set forth in such Exhibit A, and provided further that the
Optionee is in the employ of the Company or a Subsidiary on such Cliff Vesting
Date.  If the target set forth in Exhibit A for any of the first four fiscal
years referred to above is not attained, the portion of the Cliff Vesting
Option that would otherwise have vested for such fiscal year shall be treated
as vested and exercisable as of the Cliff Vesting Date for any subsequent
fiscal year ending on or before December 31, 2002 for which the target for such
subsequent year is attained, provided the Optionee is in the employ of the
Company or a Subsidiary on such Cliff Vesting Date.

         (c)     Upon the occurrence of a Liquidation Event, provided the DLJ
Entities' realized annual investment rate of return as calculated in accordance
with Exhibit B ("DLJ IRR") is at least 20%, and provided the Optionee is in the
employ of the Company or a Subsidiary as of such Liquidation Event, the Cliff
Vesting Option shall become vested and exercisable with respect to a portion of
the Shares subject thereto as to which the Option has not yet vested in
accordance with paragraph (b) above ("UNVESTED CLIFF VESTING SHARES").  In such
case, the Cliff Vesting Option will become vested and exercisable with respect
to the applicable percentage of the Unvested Cliff Vesting Shares set forth in
Exhibit B hereto, based on the DLJ IRR.

         5.      Manner of Exercise.  The Optionee (or his representative,
devisee or heir, as applicable) may exercise any portion of this Option which
has become exercisable in accordance with the terms hereof as to all or any of
the Shares then available for purchase by delivering to the Company written
notice specifying:

         with payment in full of the aggregate Exercise Price of such shares;

                 (ii)     the address to which dividends, notices, reports,

Payment shall be in cash, by certified or bank cashier's check payable to the

six-month holding period is not necessary to comply with any accounting, legal
or regulatory requirement) having a Fair Market Value equal to the full amount
of the Exercise Price therefor, or such other form as may be permitted by the
Committee.  Only one stock certificate will be issued unless the Optionee
otherwise requests in writing.  Shares purchased upon exercise of the Option
will be issued in the name of the Optionee or the Optionee's Permitted

of the Company in respect of any Shares covered by this Option until such
Shares shall have been paid for in full and issued to the Optionee.

         6.      Certificates.  Certificates issued in respect of Shares
acquired upon exercise of the Option shall, unless the Committee otherwise
determines, be registered in the name of the Optionee or its Permitted
Transferee.  When the Optionee ceases to be bound by the provisions of the
Investors' Agreement, the Company shall deliver such certificates to the
Optionee or its Permitted Transferee upon request.  Such stock certificate
shall carry such appropriate legends, and such written instructions shall be
given to the Company's transfer agent, as may be deemed necessary or advisable
by counsel to the Company in order to comply with the requirements of the
Securities Act of 1933, any state securities laws or any other applicable laws
or the Investors' Agreement.

         7.      Nontransferability.  This Option is personal to the Optionee
and may be exercised only by the Optionee or his or her representative in the
event of the Optionee's Disability or death.  This Option shall not be
transferable other than by will or the laws of descent and distribution.
Notwithstanding the foregoing, this Option may be transferred to a trust solely
for the benefit of the Optionee or the Optionee's immediate family (which shall
be deemed to include the Optionee's spouse, parents, siblings, children,
stepchildren and grandchildren).

         (a)     If the Optionee's employment with the Company and its

to the extent not controlled by the terms and conditions contained in the Plan,
are as follows:

         1. Exercise Price. The price at which each Share subject to this Option
may be purchased shall be the price set forth above.

<PAGE>   2


and 4 below, the Option may be exercised at any time until the Expiration Date,
subject to the terms of the Plan and of Section 8 below.

         3. Vesting: Time Vesting Option. As of the Date of Grant, the Time
Vesting Option shall become vested and exercisable with respect to 20% of the
Shares subject thereto. On each of the first five anniversaries of the Date of
Grant, provided the Optionee is then in the employ of the Company or a
Subsidiary, the Time Vesting Option shall become vested and exercisable with
respect to an additional 16% of the Shares subject thereto.

         4. Vesting: Cliff Vesting Option.

         (a) To the extent not previously vested in accordance with paragraph
(b) or (c) below, the Cliff Vesting Option shall become fully vested and
exercisable on the eighth anniversary of the Date of Grant, provided the
Optionee is then in the employ of the Company or a Subsidiary.

         (b) The Cliff Vesting Option shall become vested and exercisable with
respect to 20% of the Shares subject thereto on the thirtieth day following the
availability of audited financial statements for each of the five fiscal years
of the Company commencing with the fiscal year ending December 31, 1998 (each
such day a "CLIFF VESTING DATE"), provided the implied common equity value of
the Company as of the end of such fiscal year, calculated in accordance with
Exhibit A hereto, is at least equal to the target value for such fiscal year set
forth in such Exhibit A, and provided further that the Optionee is in the employ
of the Company or a Subsidiary on such Cliff Vesting Date. If the target set

not attained, the portion of the Cliff Vesting Option that would otherwise have
vested for such fiscal year shall be treated as vested and exercisable as of the
Cliff Vesting Date for any subsequent fiscal year ending on or before December
31, 2002 for which the target for such subsequent year is attained, provided the
Optionee is in the employ of the Company or a Subsidiary on such Cliff Vesting
Date.

Entities' realized annual investment rate of return as calculated in accordance
with Exhibit B ("DLJ IRR") is at least 20%, and provided the Optionee is in the
employ of the Company or a Subsidiary as of such Liquidation Event, the Cliff
Vesting Option shall become vested and exercisable with respect to a portion of
the Shares subject thereto as to which the Option has not yet vested in
accordance with paragraph (b) above ("UNVESTED CLIFF VESTING SHARES"). In such
case, the Cliff Vesting Option will become vested and exercisable with respect

         5. Manner of Exercise. The Optionee (or his representative, devisee or
heir, as applicable) may exercise any portion of this Option which has become

order of the Company, free from all collection charges, or in unencumbered
Shares (provided such shares shall have been held by the Optionee for at least
six months unless the Committee determines in its sole discretion that such

         6. Certificates. Certificates issued in respect of Shares acquired upon
exercise of the Option shall, unless the Committee otherwise determines, be
registered in the name of the Optionee or its Permitted Transferee. When the
Optionee ceases to be bound by the provisions of the Investors' Agreement, the
Company shall deliver such certificates to the Optionee or its Permitted
Transferee upon request. Such stock certificate shall carry such appropriate
legends, and such written instructions shall be given to the Company's transfer
agent, as may be deemed necessary or advisable by counsel to the Company in
order to comply with the requirements of the Securities Act of 1933, any state
securities laws or any other applicable laws or the Investors' Agreement.

         7. Nontransferability. This Option is personal to the Optionee and may
be exercised only by the Optionee or his or her representative in the event of
the Optionee's Disability or death. This Option shall not be transferable other

foregoing,

this Option may be transferred to a trust solely for the benefit of the Optionee

Optionee's spouse, parents, siblings, children, stepchildren and grandchildren).

         8. Forfeiture of Option; Right of Repurchase.

         (a) If the Optionee's employment with the Company and its Subsidiaries
shall terminate for any reason other than by the Company or its Subsidiary for
Cause, then (i) to the extent not yet vested as of the date of termination of
employment, the Option shall immediately be forfeited; and (ii) to the extent
vested as of the date of termination of employment, the Option may be retained
and exercised, in accordance with the terms of the Plan and this Award
Agreement, until the Expiration Date.

         (b) If the Optionee's employment with the Company and its Subsidiaries
shall be terminated by the Company or its Subsidiary for Cause, then the entire
Option shall immediately be forfeited, and all Shares previously acquired upon
exercise of the Option shall be subject to a right of repurchase by the Company
from the Participant or his or her Permitted Transferee at a price equal to the
Exercise Price.

         9. Change of Control. Upon a Change of Control, the Time Vesting Option
shall vest in its entirety and become immediately exercisable and, if the Change
of Control constitutes a Liquidation Event, the Cliff Vesting Option shall vest
in accordance with Section 4(c) hereof.

         10. Sale of Underlying Shares. The Optionee's right to sell any Shares
acquired upon exercise of the Option (in the case of Optionees who are party
thereto) shall be subject to the terms of the Investors' Agreement.

         11. Employment Rights. This Option does not confer on the Optionee any
right to continue in the employ of the Company or any Subsidiary or interfere in
any way with the right of the Company or any Subsidiary to determine the terms
of the Optionee's employment.

         12. Terms of Plan; Interpretations. This Option and the terms and
conditions herein set forth are subject in all respects to the terms and

Award or any tax withholding obligations will again become Shares with respect
to which Awards may be granted. Notwithstanding the foregoing and subject to
adjustment as provided in Section 4(b), no Employee of the Company may receive
Options in any calendar year that relate to more than 250,000 Shares.

         (b) Adjustments. In the event that the Committee determines that any
dividend or other distribution (whether in the form of cash, Shares, other
securities or other property), recapitalization, stock split, reverse stock
split, reorganization, reclassification, merger, consolidation, split-up,
spin-off, combination, repurchase, or exchange of Shares or other securities of
the Company, issuance of warrants or other rights to purchase Shares or other
securities of the Company, or other similar corporate transaction or event
affects the Shares such that an adjustment is determined by the Committee to be
appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Plan, then the
Committee shall, in such manner as it may deem equitable, adjust any or all of
(i) the number of Shares of the Company (or number and kind of other securities
or property) with respect to which Awards may thereafter be granted, (ii) the
number of Shares or other securities of the Company (or number and kind of other
securities or property) subject to outstanding Awards, and (iii) the grant or
exercise price with respect to any Award, or, if deemed appropriate, make
provision for a cash payment to the holder of an outstanding Award.
Notwithstanding the foregoing, the issuance of warrants by the Company in
connection with the merger of the



                                       5
<PAGE>   6

Company and Mercury Acquisition Corporation shall not give rise to any such
adjustment.

         (c) Substitute Awards. Any Shares underlying Substitute Awards shall
not be counted against the Shares available for Awards under the Plan.

         (d) Sources of Shares Deliverable Under Awards. Any Shares delivered
pursuant to an Award may consist, in whole or in part, of authorized and
unissued Shares or of treasury Shares.

employee-director of the Company or any Subsidiary, shall be eligible to be
designated a Participant.

         SECTION 6. Stock Options.

         (a) Grant. Subject to the provisions of the Plan and contractual
restrictions affecting the Company, the Committee shall have sole and complete
authority to determine the Employees to whom Options shall be granted, the
number of Shares to be covered by each Option, the exercise price therefor and
the conditions and limitations applicable to the exercise of the Option.

         (b) Exercise Price. The Committee in its sole discretion shall
establish the exercise price at the time each Option is granted; provided, that
in no event shall the exercise price per Share be less than the Fair Market
Value of a Share on the date of grant.

         (c) Exercise. Each Option shall be exercisable at such times and
subject to such terms and conditions as the Committee may, in its sole
discretion, specify in the applicable Award Agreement or thereafter. The
Committee may impose such conditions with respect to the exercise of Options,
including without limitation, any relating to the application of Federal or
state securities laws, as it may deem necessary or advisable.

         (d) Payment. No Shares shall be delivered pursuant to any exercise of
an Option until payment in full of the exercise price, or adequate provision
therefor, is received by the Company. Such payment may be made: (i) in cash;
(ii) in Shares owned by the Participant for at least six months (the value of
such Shares shall be their Fair Market Value on the date of exercise); (iii) by
a combination of cash and Shares; or (iv) in such other manner as permitted by
the Committee at the time of grant or thereafter.



                                       6

         SECTION 7. Vesting; Termination of Employment. Each Award Agreement
shall contain such terms as the Committee may in its sole discretion determine
concerning vesting, forfeiture, the Company's rights of repurchase of Shares
acquired upon exercise of an Option, and/or the effects of termination or
suspension of a Participant's employment upon the exercisability of any Option
granted thereunder.

         SECTION 8. Change of Control. The Committee, in its sole discretion,
may provide in an Award Agreement for the accelerated vesting of an Award in the
event of a Change of Control.

         SECTION 9. Amendment and Termination.

         (a) Amendments to the Plan. The Board may amend, alter, suspend,
discontinue, or terminate the Plan or any portion thereof at any time; provided
that no such amendment, alteration, suspension, discontinuation or termination
shall be made without shareholder approval if such approval is necessary to
comply with any tax or regulatory requirement, including for these purposes any
approval requirement which is a prerequisite for exemptive relief from Section
16(b) of the Exchange Act, for which or with which the Board deems it necessary
or desirable to qualify or comply. Notwithstanding anything to the contrary
herein, the Committee may amend the Plan in such manner as may be necessary so
as to have the Plan conform with local rules and regulations in any jurisdiction
outside the United States.

         (b) Amendments to Awards. Subject to the terms of the Plan and
applicable law, the Committee may waive any conditions or rights under, amend
any terms of, or alter, suspend, discontinue, cancel or terminate, any Award
theretofore granted, prospectively or retroactively; provided that any such
waiver, amendment, alteration, suspension, discontinuance, cancellation or
termination that would adversely affect the rights Participant or any holder or
beneficiary of any Award theretofore granted shall not to that extent be
effective without the consent of the affected Participant, holder or
beneficiary.

         (c) Cancellation. Any provision of this Plan or any Award Agreement to
the contrary notwithstanding, in the event of a Change of Control or an offer to
Participants generally relating to the acquisition of Shares, including through
purchase, merger or otherwise, the Committee may cause any Award granted
hereunder to be canceled in consideration of a cash payment or alternative Award
made to the holder of such canceled Award equal in value to the Fair Market
Value of such canceled Award.



                                       7

         SECTION 10. General Provisions.

         (a) Dividend Equivalents. In the sole and complete discretion of the
Committee, an Award may provide the Participant with dividends or dividend
equivalents, payable in cash, Shares, other securities or other property on a
current or deferred basis.

         (b) Nontransferability. Except to the extent otherwise provided in an
Award Agreement, no Award shall be assigned, alienated, pledged, attached, sold
or otherwise transferred or encumbered by a Participant, except by will or the
laws of descent and distribution.

         (c) No Rights to Awards. No Employee, Participant or other Person shall
have any claim to be granted any Award, and there is no obligation for
uniformity of treatment of Employees, Participants, or holders or beneficiaries
of Awards. The terms and conditions of Awards need not be the same with respect
to each recipient.

         (d) Share Certificates. Certificates issued in respect of Shares shall,
unless the Committee otherwise determines, be registered in the name of the
Participant or its Permitted Transferees and shall be deposited by such
Participant or Permitted Transferee, together with a stock power endorsed in
blank, with the Company. When the Participant ceases to be bound by any transfer
restrictions set forth herein or in the Investors' Agreement, the Company shall
deliver such certificates to the Participant upon request. Such stock
certificate shall carry such appropriate legends, and such written instructions
shall be given to the Company's transfer agent, as may be deemed necessary or
advisable by counsel to the Company in order to comply with the requirements of
the Securities Act of 1933, any state securities laws or any other applicable
laws and the Investors' Agreement. Subject to the provisions of the Investors'
Agreement, all certificates for Shares or other securities of the Company or any
Subsidiary delivered under the Plan pursuant to any Award or the exercise
thereof shall be subject to such stop transfer orders and other restrictions as
the Committee may deem advisable under the Plan or the rules, regulations and
other requirements of the Securities and Exchange Commission or any stock
exchange upon which such Shares or other securities are then listed and any
applicable laws or rules or regulations, and the Committee may cause a legend or
legends to be put on any such certificates to make appropriate reference to such
restrictions.

         (e) Withholding. A Participant may be required to pay to the Company or
any Subsidiary, and the Company or any Subsidiary shall have the right and is
hereby authorized to withhold from any Award, from any payment due or transfer
made under any Award or under the Plan or from any compensation or other amount
owing to a Participant the amount (in cash, Shares, other securities, other
Awards or other property) of any applicable withholding taxes in respect of an



                                       8
<PAGE>   9

Award, its exercise, or any payment or transfer under an Award or under the Plan
and to take such other action as may be necessary in the opinion of the Company
to satisfy all obligations for the payment of such taxes. The Committee may
provide for additional cash payments to holders of Awards to defray or offset
any tax arising from any such grant, lapse, vesting, or exercise of any Award.

         (f) Award Agreements. Each Award hereunder shall be evidenced by an
Award Agreement which shall be delivered to the Participant and shall specify
the terms and conditions of the Award and any rules applicable thereto.

         (g) No Limit on Other Compensation Arrangements. Nothing contained in
the Plan shall prevent the Company or any Subsidiary from adopting or continuing
in effect other compensation arrangements, which may, but need not, provide for
the grant of options, restricted stock, Shares and other types of Awards
provided for hereunder (subject to shareholder approval if such approval is
required), and such arrangements may be either generally applicable or
applicable only in specific cases.

         (h) No Right to Employment. The grant of an Award shall not be
construed as giving a Participant the right to be retained in the employ or
service of the Company or any Subsidiary. Further, the Company or an Subsidiary
may at any time dismiss a Participant from employment or service, free from any
liability or any claim under the Plan, unless otherwise expressly provided in
the Plan or in any Award Agreement.

         (i) Rights as a Stockholder. Subject to the provisions of the
applicable Award, no Participant or holder or beneficiary of any Award shall
have any rights as a stockholder with respect to any Shares to be issued under
the Plan until he or she has become the holder of such Shares.

         (j) Governing Law. The validity, construction, and effect of the Plan
and any rules and regulations relating to the Plan and any Award Agreement shall
be determined in accordance with the laws of the State of Delaware.

         (k) Severability. If any provision of the Plan or any Award is or
becomes or is deemed to be invalid, illegal, or unenforceable in any
jurisdiction or as to any Person or Award, or would disqualify the Plan or any
Award under any law deemed applicable by the Committee, such provision shall be
construed or deemed amended to conform to the applicable laws, or if it cannot
be construed or deemed amended without, in the determination of the Committee,
materially altering the intent of the Plan or the Award, such provision shall be
stricken as to such jurisdiction, Person or Award and the remainder of the Plan
and any such Award shall remain in full force and effect.



                                       9
<PAGE>   10

         (l) Other Laws. The Committee may refuse to issue or transfer any
Shares or other consideration under an Award if, acting in its sole discretion,
it determines that the issuance or transfer of such Shares or such other
consideration might violate any applicable law or regulation or entitle the
Company to recover the same under Section 16(b) of the Exchange Act, and any
payment tendered to the Company by a Participant in connection therewith shall
be promptly refunded to the relevant Participant, holder or beneficiary. Without
limiting the generality of the foregoing, no Award granted hereunder shall be
construed as an offer to sell securities of the Company, and no such offer shall
be outstanding, unless and until the Committee in its sole discretion has
determined that any such offer, if made, would be in compliance with all
applicable requirements of the U.S. federal securities laws and any other laws
to which such offer, if made, would be subject.

         (m) No Trust or Fund Created. Neither the Plan nor any Award shall
create or be construed to create a trust or separate fund of any kind or a
fiduciary relationship between the Company or any Subsidiary and a Participant
or any other Person. To the extent that any Person acquires a right to receive
payments from the Company or any Subsidiary pursuant to an Award, such right
shall be no greater than the right of any unsecured general creditor of the
Company or any Subsidiary.

         (n) No Fractional Shares. No fractional Shares shall be issued or
delivered pursuant to the Plan or any Award, and the Committee shall determine
whether cash or other securities or other property shall be paid or transferred
in lieu of any fractional Shares or whether such fractional Shares or any rights
thereto shall be canceled, terminated, or otherwise eliminated.

         (o) Transfer Restrictions. Shares acquired hereunder may not be sold,
assigned, transferred, pledged or otherwise disposed of, except as provided in
the Plan, the applicable Award Agreement and the Investors' Agreement.

         (p) Headings. Headings are given to the Sections and subsections of the
Plan solely as a convenience to facilitate reference. Such headings shall not be
deemed in any way material or relevant to the construction or interpretation of
the Plan or any provision thereof.

         SECTION 11. Term of the Plan.

         (a) Effective Date. The Plan shall be effective as of May 22, 1998,
subject to approval by the shareholders of the Company. Awards may be granted
hereunder prior to such shareholder approval subject in all cases, however, to
such approval.



                                       10
<PAGE>   11

         (b) Expiration Date. The Board and the Committee's authority to grant
Awards under the Plan shall terminate on the tenth anniversary of the Plan's
effective date. Unless otherwise expressly provided in the Plan or in an
applicable Award Agreement, any Award granted hereunder may, and the authority
of the Board or the Committee to amend, alter, adjust, suspend, discontinue, or
terminate any such Award or to waive any conditions or rights under any such
Award shall, continue after the authority for grant of new Awards hereunder has
been exhausted.

such Participants' names in Exhibit A hereto, or a combination of the foregoing,
provided that the combined value of all cash, cash equivalents and such

         SECTION 6. Vesting.

         (a) Of the Coinvestment Shares purchased by any Participant, 20% shall

         to such unvested Coinvestment Shares and (B) the Fair Market Value of
         such Shares on the date of purchase by the Company; and

         Value of such Shares on the date of purchase by the Company.

         (c) In the event of a Participant's termination of employment by reason

                  (i) The Company or its designee shall have the right to
         purchase all or a portion of the unvested Coinvestment Shares held by
         the Participant or his or her Permitted Transferee, at a price per
         Share equal to the lesser of (A) the sum of the Purchase Price and the
         Allocable Interest with respect to such unvested Coinvestment Shares
         and (B) the Fair Market Value of such unvested Coinvestment Shares on
         the date of purchase by the Company;

                  (ii) The Participant's estate or Permitted Transferee shall
         have the right to cause the Company to purchase all or a portion of the
         Reinvestment Shares and vested Coinvestment Shares held by the

         (e) If either the Company or, in the case of Section 7(c)(ii), a
Participant's estate or Permitted Transferee, elects to exercise their rights
under this Section 7, the Company or such estate or Permitted Transferee, as the
case may be, shall deliver written notice (a "PURCHASE NOTICE") to the other to
such effect:

                  (i) in the case of any purchase pursuant to Sections 7(c)(ii)
         or 7(c)(iii), prior to the third business day before the maturity date
         of any Loan secured by the Plan Shares to be so purchased; and

                  (ii) in the case of any other purchase under this Section 7,
         at any time within the discretion of the Company.

For purposes of this Section 7, the "date of purchase" shall mean the third
business day following the receipt of a Purchase Notice by the other party. The
proceeds of any Shares purchased from a Participant (or his or her Permitted
Transferee) pursuant to this Section 7 shall be applied first to the amount of
any interest and principal outstanding under any Loans held by such Participant
and secured by such Shares, in accordance with the terms of such Loans. Any
excess proceeds remaining after repayment of all such interest and principal
shall be paid to such Participant or his or her Permitted Transferee in cash or
by certified check; provided that if the terms of any agreement to which the
Company is a party, or any of the indentures governing any debt securities
issued by the Company or any of its Subsidiaries would prohibit the Company from
effecting such payment, payment may be effected (to the extent permitted under
such agreement or indenture) through a promissory note having such commercially
reasonable terms and interest rate as may be determined by the Company in its
reasonable discretion; and provided further that in any event such note shall
become due at such time as the prohibitions described above shall lapse.

         SECTION 8. Loan Maturity Prior to Termination of Employment.

         (a) In the event an outstanding Loan becomes due prior to the
termination of the applicable Participant's employment, the Participant shall
have the right to cause the Company to purchase that portion of such
Participant's vested Plan Shares necessary to repay the principal amount of the
Loan and any interest thereon at a per share price equal to such Shares' Fair
Market Value on the date of purchase by the Company.

         (b) If a Participant elects to exercise his or her rights under this
Section 8, the Participant shall deliver a Purchase Notice to the Company to
such effect prior to the third business day before the maturity date of the
applicable Loan.



                                       8
<PAGE>   9

The purchase price for such Shares shall be applied and paid in the manner set
forth in Section 7(e).

         SECTION 9. Investors' Agreement. A Participant shall, as a condition
precedent to the purchase of Shares, execute an instrument agreeing to be bound
by the terms of the Investors' Agreement or, at the election of the Company, a
counterpart of the Investors' Agreement. In any event, any Shares shall be
subject to the provisions in the Investors' Agreement regarding restrictions on
transfer and the Company's rights to compel sales and repurchase Shares.

         SECTION 10. Amendment and Termination.

         (a) Amendments to and Termination of the Plan. Unless the Plan shall
theretofore have been terminated as hereinafter provided, the Plan shall
terminate on, and no Purchase Agreement shall be entered into thereunder after,
May 22, 2008. Subject to any contractual restrictions affecting the Company, the
Board may amend, alter, suspend, discontinue, or terminate the Plan or any
portion thereof at any time; provided that no such amendment, alteration,
suspension, discontinuation or termination shall be made without shareholder
approval if such approval is necessary to comply with any tax or regulatory
requirement for which or with which the Board deems it necessary or desirable to
qualify or comply.

         (b) Amendments to Purchase Agreements. The Committee may waive any
conditions or rights under, amend any terms of, or alter, suspend, discontinue,
cancel or terminate, any Purchase Agreement, prospectively or retroactively;
provided that any such waiver, amendment, alteration, suspension,
discontinuance, cancellation or termination that would adversely affect the
rights of any Participant under any Purchase Agreement shall not to that extent
be effective without the consent of the affected Participant.

         SECTION 11. General Provisions.

         (a) No Rights to Participation. No Employee, Participant or other
Person shall have any claim to be granted the opportunity to purchase any Shares
hereunder, and there is no obligation for uniformity of treatment of Employees
or Participants. The terms and conditions of Purchase Agreements need not be the
same with respect to each recipient.

         (b) Share Certificates. Certificates issued in respect of Shares shall,
unless the Committee otherwise determines, be registered in the name of the
Participant or its Permitted Transferees and, so long as a Participant continues
to be governed by the provisions of any Loan, shall be deposited by such
Participant or Permitted Transferee, together with a stock power endorsed in
blank, with the



                                       9
<PAGE>   10

Company. When the Participant ceases to be bound by the provisions of the
Investors' Agreement and any Loan, the Company shall deliver such certificates
to the Participant upon request. Such stock certificate shall carry such
appropriate legends, and such written instructions shall be given to the
Company's transfer agent, as may be deemed necessary or advisable by counsel to
the Company in order to comply with the requirements of (i) the Securities Act
of 1933, any state securities laws or any other applicable laws, (ii) the
Investors' Agreement and (iii) any Loan. Subject to the provisions of the
Investors' Agreement, all certificates for Shares or other securities of the
Company or any Affiliate delivered under the Plan pursuant to any Purchase
Agreement shall be subject to such stop transfer orders and other restrictions
as the Committee may deem advisable under the Plan, the applicable Purchase
Agreement or the rules, regulations and other requirements of the SEC or any
stock exchange upon which such Shares or other securities are then listed and
any applicable laws or rules or regulations.

         (c) Execution of Purchase Agreement: Disposition of Shares. No Shares
shall be issued hereunder unless and until a Purchase Agreement shall be
executed by the Company and the Participant.

         (d) No Limit on Compensation Arrangements. Nothing contained in the
Plan shall prevent the Company or any Subsidiary from adopting or continuing in
effect compensation arrangements, which may, but need not, provide for the grant
of options, restricted stock, Shares and other types of awards (subject to
shareholder approval if such approval is required), and such arrangements may be
either generally applicable or applicable only in specific cases.

         (e) No Rights to Employment. Nothing in this Plan or in any Purchase
Agreement shall confer on any individual any right to continue in the employ of
the Company or any Subsidiary of the Company or interfere in any way with the
right of the Company or any Subsidiary of the Company to terminate his or her
employment at any time.

         (f) Governing Law. The validity, construction, and effect of the Plan
and any rules and regulations relating to the Plan and any Purchase Agreement
shall be determined in accordance with the laws of the State of Delaware,
without application of the conflict of laws principles thereof.

         (g) Severability. If any provision of the Plan or any Purchase
Agreement is or becomes or is deemed to be invalid, illegal, or unenforceable in
any jurisdiction or as to any Person or Purchase Agreement, or would disqualify
the Plan or any Purchase Agreement under any law deemed applicable by the
Committee, such provision shall be construed or deemed amended to conform to the
applicable laws, or if it cannot be construed or deemed amended without, in



                                       10
<PAGE>   11

the determination of the Committee, materially altering the intent of the Plan
or the Purchase Agreement, such provision shall be stricken as to such
jurisdiction, Person or Purchase Agreement and the remainder of the Plan and any
such Purchase Agreement shall remain in full force and effect.

         (h) Other Laws. The Committee may refuse to issue or transfer any
Shares or other consideration under a Purchase Agreement if, acting in its sole
discretion, it determines that the issuance or transfer of such Shares or such
other consideration might violate any applicable law or regulation or entitle
the Company to recover the same under Section 16(b) of the Exchange Act, and any
payment tendered to the Company by a Participant in connection therewith shall
be promptly refunded to the relevant Participant. Without limiting the
generality of the foregoing, no Purchase Agreement shall be construed as an
offer to sell securities of the Company, and no such offer shall be outstanding,
unless and until the Committee in its sole discretion has determined that any
such offer, if made, would be in compliance with all applicable requirements of
the U.S. Federal securities laws and any other laws to which such offer, if
made, would be subject.

         (i) No Trust or Fund Created. Neither the Plan nor any Purchase
Agreement shall create or be construed to create a trust or separate fund of any
kind or a fiduciary relationship between the Company or any Affiliate and a
Participant or any other Person. To the extent that any Person acquires a right
to receive payments from the Company or any Affiliate pursuant to a Purchase
Agreement, such right shall be no greater than the right of any unsecured
general creditor of the Company or any Affiliate.

         (j) No Fractional Shares. No fractional Shares shall be issued or
delivered pursuant to the Plan or any Purchase Agreement, and the Committee
shall determine whether cash or other securities or other property shall be paid
or transferred in lieu of any fractional Shares or whether such fractional
Shares or any rights thereto shall be canceled, terminated, or otherwise
eliminated.

         SECTION 12. Effective Date. The Plan shall be effective as of May 22,
1998.

("TRANSFER") any Company Securities (or solicit any offers to buy or otherwise
acquire, or take a pledge of any Company Securities) except in compliance with
the Securities Act and the terms and conditions of this Agreement.

                Any attempt to transfer any Company Securities not in compliance
with this Agreement shall be null and void and the Company shall not, and shall
cause any transfer agent not to, give any effect in the Company's stock records
to such attempted transfer.

         SECTION 3.02. Legends. In addition to any other legend that may be
required, each certificate for shares of Common Stock or Preferred Stock and
each Warrant that is issued to any Stockholder shall bear a legend in
substantially the following form:

         "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND MAY NOT BE OFFERED OR SOLD
EXCEPT IN COMPLIANCE THEREWITH. THIS SECURITY IS ALSO SUBJECT TO ADDITIONAL
RESTRICTIONS ON TRANSFER AS SET FORTH IN THE INVESTORS' AGREEMENT DATED AS OF
MAY 22, 1998, COPIES OF WHICH MAY BE

OBTAINED UPON REQUEST FROM THERMADYNE HOLDINGS CORPORATION OR ANY SUCCESSOR
THERETO."

                If any Company Securities shall cease to be Registrable
Securities under clause (i) or clause (ii) of the definition thereof, the
Company shall, upon the written request of the holder thereof, issue to such
holder a new certificate evidencing such securities without the first sentence
of the legend required by this Section endorsed thereon. If any Company
Securities cease to be subject to any and all restrictions on transfer set forth
in this Agreement, the Company shall, upon the written request of the holder
thereof, issue to such holder a new certificate evidencing such Company
Securities without the second sentence of the legend required by this Section
endorsed thereon.

         SECTION 3.03. Permitted Transferees. Notwithstanding anything in this
Agreement to the contrary, any Stockholder may at any time transfer any or all
of its Company Securities to one or more of its Permitted Transferees without
the consent of the Board or any other Stockholder or group of Stockholders and
without compliance with Sections 3.04 and 4.01 so long as (a) such Permitted
Transferee shall have agreed in writing to be bound by the terms of this
Agreement and (b) the transfer to such Permitted Transferee is not in violation
of applicable federal or state securities laws.

         SECTION 3.04.  Restrictions on Transfers by Management Stockholders.

         (a) Each Management Stockholder and each Permitted Transferee of such
Management Stockholder may transfer its Company Securities only as follows:

                  (i) in a transfer made in compliance with Section 4.01 or
         4.02, 4.03 or as permitted or required by the Thermadyne Investment
         Program, the Thermadyne New Option Program or any employment contract
         between the Company or any Subsidiary and an employee;

                  (ii) subject to the Public Offering Limitations, in a Public
         Offering in connection with the exercise of its rights under Article 5
         hereof;

                  (iii) in a transfer made at the conclusion of the Applicable
         Holdback Period (as defined in Section 5.03) following a Public
         Offering, in compliance with Rule 144 promulgated under the Securities
         Act; provided, however, that until the Restriction Termination Date,
         the Aggregate Ownership of such Management Stockholder as a result of
         such transfer shall be equal to or exceed the greater of (x) 50% of
         such




                                       13
<PAGE>   17





         Management Stockholder's Initial Ownership of Common Stock and (y) the
         percentage of such Management Stockholder's Initial Ownership that is
         equal to the Aggregate Ownership of the DLJ Entities as a percentage of
         the DLJ Entities' Initial Ownership; or

                  (iv) following the Restriction Termination Date, to any Third
         Party other than an Adverse Person for consideration consisting solely
         of cash, provided, however, that the number of Shares transferred by
         such Management Stockholder pursuant to this Section 3.04(a)(iv) in any
         twelve-month period shall not exceed 20% of the greater of (x) such
         Management Stockholder's Aggregate Ownership at the beginning of such
         twelve month period and (y) such Management Stockholder's Aggregate
         Ownership as of the date hereof.

         For purposes of this Agreement, "PUBLIC OFFERING LIMITATIONS" means (A)
except as set forth in the proviso at the end of this paragraph, no Management
Stockholder shall be permitted to exercise its rights under Section 5.02 hereof
(x) with respect to the First Public Offering and (y) until such time as the
Aggregate Ownership of the DLJ Entities shall be less than 50% of their
aggregate Initial Ownership of Common Stock and (B) in each Public Offering
following the First Public Offering, such Management Stockholder shall be
entitled to transfer a number of Shares not exceeding such Management
Stockholder's Pro Rata Portion of non-Purchased Shares; provided, however, that
notwithstanding the restrictions set forth in clauses (A) and (B), each
Management Stockholder shall be permitted to exercise its rights pursuant to
Section 5.02 hereof in respect of such Management Stockholder's Pro Rata Portion
of its Purchased Shares in any Public Offering.

         (b) The provisions of Section 3.04(a) shall terminate upon the earliest
to occur of (i) the fifth anniversary of the Closing Date and (ii) a Change of
Control. Notwithstanding the foregoing sentence, the provisions of Section
3.04(a) shall not terminate with respect to any Management Stockholder's Shares
which shall have been pledged to the Company as security in connection with any
indebtedness for borrowed money owed by such Management Stockholder to the
Company unless the proceeds from the sale of such Shares are applied to repay
such indebtedness in full.

         (c) In addition to any other restriction contained in this Agreement
and notwithstanding any other provision of this Section 3.04, neither a
Management Stockholder nor any Permitted Transferee thereof may transfer
Coinvestment Shares (as defined in the Thermadyne Investment Program) prior to
the date such Shares have vested in accordance with the terms of the Thermadyne
Investment Program and the relevant purchase agreement thereunder.

                       TAG-ALONG RIGHTS; DRAG-ALONG RIGHTS

         SECTION 4.01. Rights to Participate in Transfer. (a) If DLJ Entities
(the "SELLING PERSON") propose to transfer (other than transfers of shares of
Company Securities (i) in a Public Offering, (ii) to any Permitted Transferee of
any of the DLJ Entities or (iii) any transfer of Preferred Stock or any transfer
of Warrants made in conjunction with such a transfer of Preferred Stock), in a
transaction otherwise permitted by Article 3 hereof, a number of Company
Securities of any class of securities of the Company equal to or exceeding 10%
of the Aggregate Ownership of the DLJ Entities of securities of such class in a
single transaction or in a series of related transactions on the date of the
proposed sale (a "TAG-ALONG SALE"), the Other Stockholders may, at their option,
elect to exercise their rights under this Section 4.01 (each such Stockholder, a
"TAGGING PERSON"). In the event of such a proposed transfer, the Selling Person
shall provide each Other Stockholder written notice of the terms and conditions
of such proposed transfer ("TAG-ALONG NOTICE") and offer each Tagging Person the
opportunity to participate in such sale. The Tag-Along Notice shall identify the
number and type of Company Securities subject to the offer ("TAG-ALONG OFFER"),
the cash price at which the transfer is proposed to be made, and all other
material terms and conditions of the Tag-Along Offer, including the form of the
proposed agreement, if any. From the date of the Tag-Along Notice, each Tagging
Person shall have the right (a "TAG-ALONG RIGHT"), exercisable by written notice
("SECTION 4.01 RESPONSE NOTICE") given to the Selling Person within 10 Business
Days (the "TAG-ALONG NOTICE PERIOD"), to request that the Selling Person include
in the proposed transfer the number of Company Securities held by such Tagging
Person as is specified in such notice; provided that if the aggregate number of
Company Securities proposed to be sold by the Selling Person and all Tagging
Persons in such transaction exceeds the number of Company Securities which can
be sold on the terms and conditions set forth in the Tag-Along Notice, then only
the Tag- Along Portion of Company Securities of each Tagging Person shall be
sold pursuant to the Tag-Along Offer and the Selling Person shall sell its
Tag-Along Portion of Company Securities and such additional Company Securities
as permitted by Section 4.01(d). If the Tagging Persons exercise their Tag-Along
Rights hereunder, each Tagging Person shall deliver, together with its Section
4.01 Response Notice, to the Selling Person the certificate or certificates
representing the Company Securities of such Tagging Person to be included in the
transfer, together with a limited power-of-attorney authorizing the Selling
Person to transfer such Securities on the terms set forth in the Tag-Along
Notice.




                                       15
<PAGE>   19


Delivery of such certificate or certificates representing the Company Securities
to be transferred and the limited power-of-attorney authorizing the Selling
Person to transfer such Company Securities shall constitute an irrevocable
acceptance of the Tag-Along Offer by such Tagging Persons. If, at the end of a
120 day period after such delivery, the Selling Person has not completed the
transfer of all such Company Securities on substantially the same terms and
conditions set forth in the Tag-Along Notice, the Selling Person shall return to
each Tagging Person the limited power-of-attorney (and all copies thereof)
together with all certificates representing the Company Securities which such
Tagging Person delivered for transfer pursuant to this Section 4.01.

         (b) Concurrently with the consummation of the Tag-Along Sale, the
Selling Person shall notify the Tagging Persons thereof, shall remit to the
Tagging Persons the total consideration (by bank or certified check) for the
Company Securities of the Tagging Persons transferred pursuant thereto, and
shall, promptly after the consummation of such Tag-Along Sale, furnish such
other evidence of the completion and time of completion of such transfer and the
terms thereof as may be reasonably requested by the Tagging Persons.

         (c) If at the termination of the Tag-Along Notice Period any Tagging
Person shall not have elected to participate in the Tag-Along Sale, such Tagging
Person will be deemed to have waived its rights under Section 4.01(a) with
respect to the transfer of its securities pursuant to such Tag-Along Sale.

         (d) If any Tagging Person declines to exercise its Tag-Along Rights or
elects to exercise its Tag-Along Rights with respect to less than such Tagging
Person's Tag-Along Portion, the DLJ Entities shall be entitled to transfer,
pursuant to the Tag-Along Offer, a number of Company Securities held by the DLJ
Entities equal to the number of Company Securities constituting the portion of
such Tagging Person's Tag-Along Portion with respect to which Tag-Along Rights
were not exercised.

         (e) The DLJ Entities and any Tagging Person who exercises the Tag-
Along Rights pursuant to this Section 4.01 may sell the Company Securities
subject to the Tag-Along Offer on the terms and conditions set forth in the Tag-
Along Notice (provided, however, that the cash price payable in any such sale
may exceed the cash price specified in the Tag-Along Notice by up to 10%) within
120 days of the date on which Tag-Along Rights shall have been waived, exercised
or expire.

         SECTION 4.02. Right to Compel Participation in Certain Transfers. (a)
If (i) the DLJ Entities propose to transfer not less than 50% of their Initial
Ownership of Common Stock to a Third Party in a bona fide sale or (ii) the DLJ



                                       16
<PAGE>   20



Entities propose a transfer in which the shares of Common Stock to be
transferred by the DLJ Entities and their Permitted Transferees constitute more
than 50% of the outstanding shares of Common Stock (a "SECTION 4.02 SALE"), the
DLJ Entities may at their option require all Other Stockholders to sell the
Drag-Along Portion of the Subject Securities ("DRAG-ALONG RIGHTS") then held by
every Other Stockholder, and (subject to and at the closing of the Section 4.02
Sale) to exercise all, but not less than all, of the options or Warrants held by
every Other Stockholder and to sell all of the shares of Common Stock received
upon such exercise to such Third Party, for the same consideration per share of
Common Stock and otherwise on the same terms and conditions as the DLJ Entities;
provided that any Other Stockholder who holds options or Warrants the exercise
price per share of which is greater than the per share price at which the Shares
are to be sold to the Third Party may, if required by the DLJ Entities to
exercise such options, in place of such exercise, submit to irrevocable
cancellation thereof without any liability for payment of any exercise price
with respect thereto. In the event the Section 4.02 Sale is not consummated with
respect to any shares acquired upon exercise of such options or Warrants, or the
Section 4.02 Sale is not consummated, such options or Warrants shall be deemed
not to have been exercised or canceled, as applicable. DLJMB shall provide
written notice of such Section 4.02 Sale to the Other Stockholders (a "SECTION
4.02 NOTICE") not later than the 15th day prior to the proposed Section 4.02
Sale. The Section 4.02 Notice shall identify the transferee, the number of
Subject Securities, the consideration for which a transfer is proposed to be
made (the "SECTION 4.02 SALE PRICE") and all other material terms and conditions
of the Section 4.02 Sale. The number of shares of Common Stock, Preferred Stock,
and/or Warrants to be sold by each Other Stockholder will be the Drag-Along
Portion of the shares of Common Stock, Preferred Stock, and/or Warrants that
such Other Stockholder owns. Subject to Sections 4.02 and 4.03, each Other
Stockholder shall be required to participate in the Section 4.02 Sale on the
terms and conditions set forth in the Section 4.02 Notice and to tender all its
Subject Securities as set forth below. The price payable in such transfer shall
be the Section 4.02 Sale Price. Not later than the 10th day following the date
of the Section 4.02 Notice (the "SECTION 4.02 NOTICE PERIOD"), each of the Other
Stockholders shall deliver to a representative of DLJMB designated in the
Section 4.02 Notice certificates representing all Subject Securities
representing the Drag Along Portion held by such Other Stockholder, duly
endorsed, together with all other documents required to be executed in
connection with such Section 4.02 Sale. If an Other Stockholder should fail to
deliver such certificates to DLJMB, the Company shall cause the books and
records of the Company to show that such Subject Securities are bound by the
provisions of this Section 4.02 and Section 4.03 and that such Subject
Securities shall be transferred to the purchaser of the Subject Securities
immediately upon surrender for transfer by the holder thereof.



                                       17

         (b) The DLJ Entities shall have a period of 90 days from the date of
receipt of the Section 4.02 Notice to consummate the Section 4.02 Sale on the
terms and conditions set forth in such Section 4.02 Sale Notice. If the Section
4.02 Sale shall not have been consummated during such period, DLJMB shall return
to each of the Other Stockholders all certificates representing Subject
Securities that such Other Stockholder delivered for transfer pursuant hereto,
together with any documents in the possession of DLJMB executed by the Other
Stockholder in connection with such proposed transfer, and all the restrictions
on transfer contained in this Agreement or otherwise applicable at such time
with respect to Common Stock owned by the Other Stockholders shall again be in
effect.

         (c) Concurrently with the consummation of the transfer of Company
Securities pursuant to this Section 4.02 and Section 4.03, DLJMB shall give
notice thereof to all Stockholders, shall remit to each of the Stockholders who
have surrendered their certificates the total consideration (by bank or
certified check) for the Subject Securities transferred pursuant hereto and
shall furnish such other evidence of the completion and time of completion of
such transfer and the terms thereof as may be reasonably requested by such
Stockholders.

         SECTION 4.03. Certain Rights. It is understood and agreed that the
employment agreements or associated restricted stock purchase agreements between
one or more Management Stockholders and the Company or any Subsidiary may
contain provisions permitting or requiring, under certain circumstances, such
Management Stockholders to sell to the Company or a Subsidiary, and permitting
or requiring, under certain circumstances, the Company or such Subsidiary to
purchase from such Management Stockholder, Company Securities. Such provisions
may, by the terms of such agreements, remain effective notwithstanding that the
employment relationship created by such employment agreements has been
terminated, in which event such provisions are deemed to be incorporated herein
and made a part hereof, to the extent appropriate.

                               REGISTRATION RIGHTS

         SECTION 5.01.  Demand Registration. (a) If the Company shall receive a
written request by the DLJ Entities or their Permitted Transferees (any such
requesting Person, a "SELLING STOCKHOLDER") that the Company effect the
registration under the Securities Act of all or a portion of such Selling





                                       18
<PAGE>   22

Stockholder's Registrable Securities, and specifying the intended method of
disposition thereof, then the Company shall promptly give written notice of such
requested registration (a "DEMAND REGISTRATION") at least 5 days prior to the
anticipated filing date of the registration statement relating to such Demand
Registration to the Other Stockholders and thereupon will use its best efforts
to effect, as expeditiously as possible, the registration under the Securities
Act of:

                  (i) the Registrable Securities which the Company has been so
         requested to register by the Selling Stockholders, then held by the
         Selling Stockholders; and

                  (ii) subject to the restrictions set forth in Section 3.04,
         all other Registrable Securities of the same type as that to which the
         request by the Selling Stockholders relates which any Other Stockholder
         entitled to request the Company to effect an Incidental Registration
         (as such term is defined in Section 5.02) pursuant to Section 5.02 (all
         such Stockholders, together with the Selling Stockholders, the
         "HOLDERS") has requested the Company to register by written request
         received by the Company within 2 days after the receipt by such Holders
         of such written notice given by the Company,

all to the extent necessary to permit the disposition (in accordance with the
intended methods thereof as aforesaid) of the Registrable Securities so to be
registered; provided that, subject to Section 5.01(d) hereof, the Company shall
not be obligated to effect more than six Demand Registrations for the DLJ
Entities; and provided further that the Company shall not be obligated to effect
a Demand Registration unless the aggregate proceeds expected to be received from
the sale of the Common Stock to be included in such Demand Registration, in the
reasonable opinion of DLJMB exercised in good faith, equals or exceeds (x)
$50,000,000 if such Demand Registration would constitute the First Public
Offering, or (y) $10,000,000 in all other cases. In no event will the Company be
required to effect more than one Demand Registration within any four-month
period.

          (b) Promptly after the expiration of the 2-day period referred to in
Section 5.01(a)(ii) hereof, the Company will notify all the Holders to be
included in the Demand Registration of the other Holders and the number of
Registrable Securities requested to be included therein. The Selling
Stockholders requesting a registration under this Section may, at any time prior
to the effective date of the registration statement relating to such
registration, revoke such request, without liability to any of the other
Holders, by providing a written notice to the Company revoking such request, in
which case such request, so revoked, shall be considered a Demand Registration
unless the participating Stockholders reimburse the



                                       19
<PAGE>   23


Company for all costs incurred by the Company in connection with such
registration, or unless such revocation arose out of the fault of the Company,
in which case such request shall not be considered a Demand Registration.

         (c) The Company will pay all Registration Expenses in connection with
any Demand Registration.

         (d) A registration requested pursuant to this Section shall not be
deemed to have been effected (i) unless the registration statement relating
thereto (A) has become effective under the Securities Act and (B) has remained
effective for a period of at least 180 days (or such shorter period in which all
Registrable Securities of the Holders included in such registration have
actually been sold thereunder); provided that if after any registration
statement requested pursuant to this Section becomes effective (x) such
registration statement is interfered with by any stop order, injunction or other
order or requirement of the SEC or other governmental agency or court and (y)
less than 75% of the Registrable Securities included in such registration
statement has been sold thereunder, such registration statement shall not be
considered a Demand Registration or (ii) if the Maximum Offering Size (as
defined below) is reduced in accordance with Section 5.01(e) such that less than
66 2/3% of the Registrable Securities of the Selling Stockholders sought to be
included in such registration are included.

         (e) If a Demand Registration involves an Underwritten Public Offering
and the managing underwriter shall advise the Company and the Selling
Stockholders that, in its view, (i) the number of Registrable Securities
requested to be included in such registration (including any securities which
the Company proposes to be included which are not Registrable Securities) or
(ii) the inclusion of some or all of the Registrable Securities owned by the
Holders, in any such case, exceeds the largest number of securities which can be
sold without having an adverse effect on such offering, including the price at
which such securities can be sold (the "MAXIMUM OFFERING SIZE"), the Company
will include in such registration, in the priority listed below, up to the
Maximum Offering Size:

                       (A) first, all Benchmark Securities requested to be
                  registered by the Selling Stockholder and by all other DLJ
                  Entities and their Permitted Transferees (allocated, if
                  necessary for the offering not to exceed the Maximum Offering
                  Size, pro rata among such entities on the basis of the
                  relative number of shares of Registrable Securities requested
                  to be registered);




                                       20
<PAGE>   24



                       (B) second, all Registrable Securities (other than
                  Benchmark Securities) requested to be included in such
                  registration by all DLJ Entities and their Permitted
                  Transferees and any other Holder (allocated, if necessary for
                  the offering not to exceed the Maximum Offering Size, pro rata
                  among such DLJ Entities and their Permitted Transferees and
                  such other Holders on the basis of the relative number of
                  shares of Registrable Securities (excluding any Benchmark
                  Securities) requested to be included in such registration);
                  and

                       (C) third, any securities proposed to be registered by
                  the Company.

         (f) If, in connection with any Demand Registration pursuant to this
Section with respect to the Preferred Stock, any Selling Stockholder shall seek
to transfer any Warrants together with shares of Preferred Stock, the Company
shall at the request of any such Stockholder effect a registration of such
Warrants to which the provisions of this Article 5 shall apply mutatis mutandis
and a registration, pursuant to a shelf registration statement, so as to permit
the resale of the shares of Common Stock for which any Warrants so transferred
may be exercisable. The Company shall maintain the effectiveness of any such
shelf registration statement, and take all actions necessary to permit resale of
such Common Stock as may be required by applicable state securities laws.

         SECTION 5.02. Incidental Registration. (a) If the Company proposes to
register any Company Securities under the Securities Act (other than a
registration (A) on Form S-8 or S-4 or any successor or similar forms, (B)
relating to Common Stock issuable upon exercise of employee stock options or in
connection with any employee benefit or similar plan of the Company or (C) in
connection with a direct or indirect acquisition by the Company of another
company), whether or not for sale for its own account, it will each such time,
subject to the provisions of Section 5.02(b), give prompt written notice at
least 30 days prior to the anticipated filing date of the registration statement
relating to such registration to each DLJ Entity and each Other Stockholder,
which notice shall set forth such Stockholder's rights under this Section 5.02
and shall offer such Stockholders the opportunity to include in such
registration statement such number of Registrable Securities of the same type as
are proposed to be registered as each such Stockholder may request (an
"INCIDENTAL REGISTRATION"). Upon the written request of any such Stockholder
made within 15 days after the receipt of notice from the Company (which request
shall specify the number of Registrable Securities intended to be disposed of by
such Stockholder), the Company will use its best efforts to effect the
registration under the Securities Act of all Registrable Securities which the
Company has been so requested to register by such



                                       21
<PAGE>   25


Stockholders, to the extent requisite to permit the disposition of the
Registrable Securities so to be registered; provided that (I) if such
registration involves a Public Offering, all such Stockholders requesting to be
included in the Company's registration must sell their Registrable Securities to
the underwriters selected as provided in Section 5.04(f) on the same terms and
conditions as apply to the Company and (II) if, at any time after giving written
notice of its intention to register any stock pursuant to this Section 5.02(a)
and prior to the effective date of the registration statement filed in
connection with such registration, the Company shall determine for any reason
not to register such securities, the Company shall give written notice to all
such Stockholders and, thereupon, shall be relieved of its obligation to
register any Registrable Securities in connection with such registration
(without prejudice, however, to rights of any DLJ Entity under Section 5.01). No
registration effected under this Section 5.02 shall relieve the Company of its
obligations to effect a Demand Registration to the extent required by Section
5.01. The Company will pay all Registration Expenses in connection with each
registration of Registrable Securities requested pursuant to this Section 5.02.

         (b) If a registration pursuant to this Section 5.02 involves a Public
Offering (other than in the case of a Public Offering requested by any DLJ
Entity or any of their Permitted Transferees or the Other Stockholders in a
Demand Registration, in which case the provisions with respect to priority of
inclusion in such offering set forth in Section 5.01(e) shall apply) and the
managing underwriter advises the Company that, in its view, the number of Shares
that the Company and such Stockholders intend to include in such registration
exceeds the Maximum Offering Size, the Company will include in such
registration, in the following priority, up to the Maximum Offering Size:

                  (i) first, so much of the securities proposed to be registered
         by the Company as would not cause the offering to exceed the Maximum
         Offering Size;

                  (ii) second, all Benchmark Securities requested to be included
         in such registration statement by the DLJ Entities and their Permitted
         Transferees (allocated, if necessary for the offering not to exceed the
         Maximum Offering Size, pro rata among such entities on the basis of the
         relative number of shares of Registrable Securities requested to be so
         included); and

                  (iii) third, all Registrable Securities other than Benchmark
         Securities requested to be included in such registration by any DLJ
         Entity and its Permitted Transferees or any Other Stockholder pursuant
         to this Section 5.02 (allocated, if necessary for the offering not to
         exceed the



                                       22
<PAGE>   26



         Maximum Offering Size, pro rata among such Stockholders on the basis of
         the relative number of shares of Registrable Securities (excluding any
         Benchmark Securities) so requested to be included in such
         registration).

         SECTION 5.03. Holdback Agreements. If any registration of Registrable
Securities shall be in connection with a Public Offering, each DLJ Entity and
its Permitted Transferees and each Other Stockholder agrees not to effect any
public sale or distribution, including any sale pursuant to Rule 144, or any
successor provision, under the Securities Act, of any Registrable Securities,
and not to effect any such public sale or distribution of any other Common Stock
of the Company or of any stock convertible into or exchangeable or exercisable
for any Common Stock of the Company (in each case, other than as part of such
Public Offering) during the 14 days prior to the effective date of such
registration statement (except as part of such registration) or during the
period after such effective date equal to the lesser of (i) such period of time
as agreed between such managing underwriter and the Company and (ii) 180 days
(such lesser period, the "APPLICABLE HOLDBACK PERIOD").

         SECTION 5.04. Registration Procedures. Whenever Stockholders request
that any Registrable Securities be registered pursuant to Section 5.01 or 5.02,
the Company will, subject to the provisions of such Sections, use its best
efforts to effect the registration and the sale of such Registrable Securities
in accordance with the intended method of disposition thereof as quickly as
practicable, and in connection with any such request:

         (a) The Company will as expeditiously as possible prepare and file with
the SEC a registration statement on any form for which the Company then
qualifies or which counsel for the Company shall deem appropriate and which form
shall be available for the sale of the Registrable Securities to be registered
thereunder in accordance with the intended method of distribution thereof, and
use its best efforts to cause such filed registration statement to become and
remain effective for a period of not less than 180 days.

         (b) The Company will, if requested, prior to filing a registration
statement or prospectus or any amendment or supplement thereto, furnish to
participating Stockholder and each underwriter, if any, of the Registrable
Securities covered by such registration statement copies of such registration
statement as proposed to be filed, and thereafter the Company will furnish to
such Stockholder and underwriter, if any, such number of copies of such
registration statement, each amendment and supplement thereto (in each case
including all exhibits thereto and documents incorporated by reference therein),
the prospectus included in such registration statement (including each
preliminary prospectus) and such other documents as such Stockholder or
underwriter may reasonably



                                       23
<PAGE>   27


request in order to facilitate the disposition of the Registrable Securities
owned by such Stockholder.

         (c) After the filing of the registration statement, the Company will
promptly notify each Stockholder holding Registrable Securities covered by such
registration statement of any stop order issued or threatened by the SEC and
take all reasonable actions required to prevent the entry of such stop order or
to remove it if entered.

         (d) The Company will use its best efforts to (i) register or qualify
the Registrable Securities covered by such registration statement under such
other securities or blue sky laws of such jurisdictions in the United States as
any Stockholder holding such Registrable Securities reasonably (in light of such
Stockholder's intended plan of distribution) requests and (ii) cause such
Registrable Securities to be registered with or approved by such other
governmental agencies or authorities as may be necessary by virtue of the
business and operations of the Company and do any and all other acts and things
that may be reasonably necessary or advisable to enable such Stockholder to
consummate the disposition of the Registrable Securities owned by such
Stockholder; provided that the Company will not be required to (A) qualify
generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this paragraph (d), (B) subject itself to taxation
in any such jurisdiction or (C) consent to general service of process in any
such jurisdiction.

         (e) The Company will immediately notify each Stockholder holding such
Registrable Securities, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the occurrence of an event
requiring the preparation of a supplement or amendment to such prospectus so
that, as thereafter delivered to the purchasers of such Registrable Securities,
such prospectus will not contain an untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading and promptly prepare and make available to
each such Stockholder any such supplement or amendment.

         (f) (i) The DLJ Entities will have the right, in their sole discretion,
to select an underwriter or underwriters in connection with any Public Offering
resulting from the exercise by any such DLJ Entity or its Permitted Transferee
of a Demand Registration, which underwriter or underwriters may include any
Affiliate of any DLJ Entity and (ii) the Company will select an underwriter or
underwriters in connection with any other Public Offering. In connection with
any Public Offering, the Company will enter into customary agreements (including
an underwriting agreement in customary form) and take such other




                                       24
<PAGE>   28

actions as are reasonably required in order to expedite or facilitate the
disposition of Registrable Securities in any such Public Offering, including the
engagement of a "qualified independent underwriter" in connection with the
qualification of the underwriting arrangements with the NASD.

         (g) Upon the execution of confidentiality agreements in form and
substance satisfactory to the Company, the Company will make available for
inspection by any Stockholder and any underwriter participating in any
disposition pursuant to a registration statement being filed by the Company
pursuant to this Section 5.04 and any attorney, accountant or other professional
retained by any such Stockholder or underwriter (collectively, the
"INSPECTORS"), all financial and other records, pertinent corporate documents
and properties of the Company (collectively, the "RECORDS") as shall be
reasonably necessary to enable them to exercise their due diligence
responsibility, and cause the Company's officers, directors and employees to
supply all information reasonably requested by any Inspectors in connection with
such registration statement. Records that the Company determines, in good faith,
to be confidential and that it notifies the Inspectors are confidential shall
not be disclosed by the Inspectors unless (i) the disclosure of such Records is
necessary to avoid or correct a misstatement or omission in such registration
statement or (ii) the release of such Records is ordered pursuant to a subpoena
or other order from a court of competent jurisdiction. Each Stockholder agrees
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 Company Securities or its Affiliates unless and until such
is made generally available to the public. Each Stockholder further agrees that
it will, upon learning that disclosure of such Records is sought in a court of
competent jurisdiction, give notice to the Company and allow the Company, at its
expense, to undertake appropriate action to prevent disclosure of the Records
deemed confidential.

         (h) The Company will furnish to each such Stockholder and to each such
underwriter, if any, a signed counterpart, addressed to such underwriter, of (i)
an opinion or opinions of counsel to the Company and (ii) a comfort letter or
comfort letters from the Company's independent public accountants, each in
customary form and covering such matters of the type customarily covered by
opinions or comfort letters, as the case may be, as a majority of such
Stockholders or the managing underwriter therefor reasonably requests.

         (i) The Company will otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC, and make available to its
stockholders, as soon as reasonably practicable, an earnings statement covering
a period of 12 months, beginning within three months after the effective date of
the




                                       25
<PAGE>   29


registration statement, which earnings statement shall satisfy the provisions of
Section 11(a) of the Securities Act.

         The Company may require each such Stockholder to promptly furnish in
writing to the Company such information regarding the distribution of the
Registrable Securities as the Company may from time to time reasonably request
and such other information as may be legally required in connection with such
registration.

         Each such Stockholder agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 5.04(e),
such Stockholder will forthwith discontinue disposition of Registrable
Securities pursuant to the registration statement covering such Registrable
Securities until such Stockholder's receipt of the copies of the supplemented or
amended prospectus contemplated by Section 5.04(e), and, if so directed by the
Company, such Stockholder will deliver to the Company all copies, other than any
permanent file copies then in such Stockholder's possession, of the most recent
prospectus covering such Registrable Securities at the time of receipt of such
notice. In the event that the Company shall give such notice, the Company shall
extend the period during which such registration statement shall be maintained
effective (including the period referred to in Section 5.04(a)) by the number of
days during the period from and including the date of the giving of notice
pursuant to Section 5.04(e) to the date when the Company shall make available to
such Stockholder a prospectus supplemented or amended to conform with the
requirements of Section 5.04(e).

         SECTION 5.05. Indemnification by the Company. The Company agrees to
indemnify and hold harmless each Stockholder holding Registrable Securities
covered by a registration statement, its officers, directors and agents, and
each person, if any, who controls such Stockholder within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act from and against any
and all losses, claims, damages and liabilities caused by any untrue statement
or alleged untrue statement of a material fact contained in any registration
statement or prospectus relating to the Registrable Securities (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) or any preliminary prospectus, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or omission or alleged untrue statement or omission based upon information
furnished in writing to the Company by such Stockholder or on such Stockholder's
behalf expressly for use therein; provided that with respect to any untrue
statement or omission or alleged untrue statement or omission made in any
preliminary prospectus, or in any



                                       26
<PAGE>   30



prospectus, as the case may be, the indemnity agreement contained in this
paragraph shall not apply to the extent that any such loss, claim, damage,
liability or expense results from the fact that a current copy of the prospectus
(or, in the case of a prospectus, the prospectus as amended or supplemented) was
not sent or given to the person asserting any such loss, claim, damage,
liability or expense at or prior to the written confirmation of the sale of the
Registrable Securities concerned to such person if it is determined that the
Company has provided such prospectus and it was the responsibility of such
Stockholder to provide such person with a current copy of the prospectus (or
such amended or supplemented prospectus, as the case may be) and such current
copy of the prospectus (or such amended or supplemented prospectus, as the case
may be) would have cured the defect giving rise to such loss, claim, damage,
liability or expense. The Company also agrees to indemnify any underwriters of
the Registrable Securities, their officers and directors and each person who
controls such underwriters on substantially the same basis as that of the
indemnification of the Stockholders provided in this Section 5.05.

         SECTION 5.06. Indemnification by Participating Stockholders. Each
Stockholder holding Registrable Securities included in any registration
statement agrees, severally but not jointly, to indemnify and hold harmless the
Company, its officers, directors and agents and each person, if any, who
controls the Company within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act to the same extent as the foregoing
indemnity from the Company to such Stockholder, but only (i) with respect to
information furnished in writing by such Stockholder or on such Stockholder's
behalf expressly for use in any registration statement or prospectus relating to
the Registrable Securities, or any amendment or supplement thereto, or any
preliminary prospectus or (ii) to the extent that any loss, claim, damage,
liability or expense described in Section 5.05 results from the fact that a
current copy of the prospectus (or, in the case of a prospectus, the prospectus
as amended or supplemented) was not sent or given to the person asserting any
such loss, claim, damage, liability or expense at or prior to the written
confirmation of the sale of the Registrable Securities concerned to such person
if it is determined that it was the responsibility of such Stockholder to
provide such person with a current copy of the prospectus (or such amended or
supplemented prospectus, as the case may be) and such current copy of the
prospectus (or such amended or supplemented prospectus, as the case may be)
would have cured the defect giving rise to such loss, claim, damage, liability
or expense. Each such Stockholder also agrees to indemnify and hold harmless
underwriters of the Registrable Securities, their officers and directors and
each person who controls such underwriters on substantially the same basis as
that of the indemnification of the Company provided in this Section 5.06. As a
condition to including Registrable Securities in any registration statement
filed in accordance with Article 5 hereof, the Company may require that it shall
have




                                       27
<PAGE>   31


received an undertaking reasonably satisfactory to it from any underwriter to
indemnify and hold it harmless to the extent customarily provided by
underwriters with respect to similar securities.

         SECTION 5.07. Conduct of Indemnification Proceedings. In case any
proceeding (including any governmental investigation) shall be instituted
involving any person in respect of which indemnity may be sought pursuant to
this Article 5, such person (an "INDEMNIFIED PARTY") shall promptly notify the
person against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in
writing and the Indemnifying Party shall assume the defense thereof, including
the employment of counsel reasonably satisfactory to such Indemnified Party, and
shall assume the payment of all fees and expenses; provided that the failure of
any Indemnified Party so to notify the Indemnifying Party shall not relieve the
Indemnifying Party of its obligations hereunder except to the extent that the
Indemnifying Party is materially prejudiced by such failure to notify. In any
such proceeding, any Indemnified Party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Party unless (i) the Indemnifying Party and the Indemnified
Party shall have mutually agreed to the retention of such counsel or (ii) in the
reasonable judgment of such Indemnified Party representation of both parties by
the same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood that the Indemnifying Party shall not,
in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) at any time for
all such Indemnified Parties, and that all such fees and expenses shall be
reimbursed as they are incurred. In the case of any such separate firm for the
Indemnified Parties, such firm shall be designated in writing by the Indemnified
Parties. The Indemnifying Party shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such
consent, or if there be a final judgment for the plaintiff, the Indemnifying
Party shall indemnify and hold harmless such Indemnified Parties from and
against any loss or liability (to the extent stated above) by reason of such
settlement or judgment. No Indemnifying Party shall, without the prior written
consent of the Indemnified Party, effect any settlement of any pending or
threatened proceeding in respect of which any Indemnified Party is or could have
been a party and indemnity could have been sought hereunder by such Indemnified
Party, unless such settlement includes an unconditional release of such
Indemnified Party from all liability arising out of such proceeding.

         SECTION 5.08. Contribution. If the indemnification provided for in this
Article 5 is unavailable to the Indemnified Parties in respect of any losses,
claims, damages or liabilities referred to herein, then each such Indemnifying
Party, in



                                       28
<PAGE>   32

lieu of indemnifying such Indemnified Party, shall contribute to the amount paid
or payable by such Indemnified Party as a result of such losses, claims, damages
or liabilities (i) as between the Company and the Stockholders holding
Registrable Securities covered by a registration statement on the one hand and
the underwriters on the other, in such proportion as is appropriate to reflect
the relative benefits received by the Company and such Stockholders on the one
hand and the underwriters on the other, from the offering of the Registrable
Securities, or if such allocation is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits but also
the relative fault of the Company and such Stockholders on the one hand and of
such underwriters on the other in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities, as well as any
other relevant equitable considerations and (ii) as between the Company on the
one hand and each such Stockholder on the other, in such proportion as is
appropriate to reflect the relative fault of the Company and of each such
Stockholder in connection with such statements or omissions, as well as any
other relevant equitable considerations. The relative benefits received by the
Company and such Stockholders on the one hand and such underwriters on the other
shall be deemed to be in the same proportion as the total proceeds from the
offering (net of underwriting discounts and commissions but before deducting
expenses) received by the Company and such Stockholders bear to the total
underwriting discounts and commissions received by such underwriters, in each
case as set forth in the table on the cover page of the prospectus. The relative
fault of the Company and such Stockholders on the one hand and of such
underwriters on the other shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company and such Stockholders or by such underwriters. The
relative fault of the Company on the one hand and of each such Stockholder on
the other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by such party,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

         The Company and the Stockholders agree that it would not be just and
equitable if contribution pursuant to this Section 5.08 were determined by pro
rata allocation (even if the underwriters 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 in the immediately preceding paragraph. The
amount paid or payable by an Indemnified Party as a result of the losses,
claims, damages or liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such Indemnified Party
in connection with investigating or



                                       29
<PAGE>   33


defending any such action or claim. Notwithstanding the provisions of this
Section 5.08, no underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Registrable
Securities underwritten by it and distributed to the public were offered to the
public exceeds the amount of any damages which such underwriter has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission, and no Stockholder shall be required to contribute
any amount in excess of the amount by which the total price at which the
Registrable Securities of such Stockholder were offered to the public exceeds
the amount of any damages which such Stockholder has otherwise been required to
pay by reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. Each such
Stockholder's obligation to contribute pursuant to this Section 5.08 is several
in the proportion that the proceeds of the offering received by such Stockholder
bears to the total proceeds of the offering received by all such Stockholders
and not joint.

         SECTION 5.09. Participation in Public Offering. No Person may
participate in any Public Offering hereunder unless such Person (a) agrees to
sell such Person's securities on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements an (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements and the provisions of
this Agreement in respect of registration rights.

         SECTION 5.10. Other Indemnification. Indemnification similar to that
specified herein (with appropriate modifications) shall be given by the Company
and each Stockholder participating therein with respect to any required
registration or other qualification of securities under any federal or state law
or regulation or governmental authority other than the Securities Act.

         SECTION 5.11. Cooperation by the Company. In the event any Stockholder
shall transfer any Registrable Securities pursuant to Rule 144A under the
Securities Act, the Company shall cooperate with such Stockholder (which shall
include, without limitation, making registration rights with respect to the
Registrable Securities to be sold (or securities issuable or to be issued in
exchange therefor) available to the ultimate purchasers thereof) and shall
provide to such Stockholder such information as such Stockholder shall
reasonably request.

         SECTION 6.02. Binding Effect; Benefit. This Agreement shall inure to
the benefit of and be binding upon the parties hereto and their respective

by reason of this Agreement.

         SECTION 6.03. Exclusive Financial and Investment Banking Advisor.
During the period from and including the date hereof through and including the

investment banking advisor of the Company. DLJSC or such Affiliate shall be
entitled to reimbursement from the Company for all expenses incurred by DLJSC or
such Affiliate (including, without limitation, fees and expenses of counsel) as
financial and investment banking advisor of the Company.

         SECTION 6.04. Assignability. This Agreement shall not be assignable by
any party hereto, except that any Person acquiring Shares who is required by the
terms of this Agreement or any employment agreement or stock purchase, option,
stock option or other compensation plan of the Company or any Subsidiary to
become a party hereto shall (unless already bound hereby) execute and deliver to
the Company an agreement to be bound by this Agreement and shall thenceforth be
a "STOCKHOLDER". Any Stockholder who ceases to own beneficially any Shares shall
cease to be bound by the terms hereof (other than the provisions of Sections
5.05, 5.06, 5.07, 5.08, and 5.10 applicable to such Stockholder with respect to
any offering of Registrable Securities completed before the date such
Stockholder ceased to own any Shares).

         SECTION 6.05. Amendment; Waiver; Termination. No provision of this
Agreement may be waived except by an instrument in writing executed by the party
against whom the waiver is to be effective. No provision of this Agreement may

executed by the Company with the approval of the Board and Stockholders holding
at least 75% of the outstanding Shares; provided that any amendment or other
modification of this Agreement that would adversely affect any Founding
Stockholder may be effected only with the consent of such Stockholder.

connection with, this Agreement or the transactions contemplated hereby may be
brought in the United States District Court for the Southern District of New
York or any other New York State court sitting in New York City, and each of the
parties hereby consents to the non-exclusive jurisdiction of such courts (and of
the appropriate appellate courts therefrom) in any such suit, action or
proceeding and irrevocably waives, to the fullest extent permitted by law, any
objection which it may now or hereafter have to the laying of the venue of any
such suit, action or proceeding in any such court or that any such suit, action
or proceeding which is brought in any such court has been brought in an
inconvenient forum. Process in any such suit, action or proceeding may be served
on any party anywhere in the world, whether within or without the jurisdiction
of any such court. Without limiting the foregoing, each party agrees that
service of process on such party as provided in Section 6.06 shall be deemed
effective service of process on such party.

         The Issuers initially appoint The Depository Trust Issuers ("DTC") to
act as Depositary with respect to the Global Notes.

         The Issuers initially appoint the Trustee to act as the Registrar and
Paying Agent and to act as Note Custodian with respect to the Global Notes.

SECTION 2.04.     PAYING AGENT TO HOLD MONEY IN TRUST.

         The Issuers shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium or Liquidated Damages, if any, or interest on the Notes, and
will notify the Trustee of any default by the Issuers in making any such
payment. While any such default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee. The Issuers at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment
over to the Trustee, the Paying Agent (if other than the Issuers or a
Subsidiary) shall have no further liability for the money. If the Issuers or a
Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the Holders all money held by it as Paying Agent. Upon

Trustee shall serve as Paying Agent for the Notes.

Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of the Holders of
Notes and the Issuers shall otherwise comply with TIA ss. 312(a).

              Global Note may be transferred to Persons who take delivery
              thereof in the form of a beneficial interest in an Unrestricted
              Global Note. No written orders or instructions shall be required
              to be delivered to the Registrar to effect the transfers described

              Definitive Notes be issued upon the transfer or exchange of
              beneficial interests in the Regulation S Temporary Global Note
              prior to (x) the expiration of the Restricted Period and (y) the
              receipt by the Registrar of any certificates required pursuant to
              Rule 903 under the Securities Act. Upon consummation of an
              Exchange Offer by the Issuers in accordance with Section 2.06(f)
              hereof, the requirements of this Section 2.06(b)(ii) shall be

              this Indenture and the Notes or otherwise applicable under the
              Securities Act, the Trustee shall adjust the principal amount of

              registration of transfer or exchange of Global Notes or Definitive
              Notes shall be the valid obligations of the Issuers, evidencing
              the same debt, and entitled to the same benefits under this
              Indenture, as the Global Notes or Definitive Notes surrendered
              upon such registration of transfer or exchange.

                  (v) The Issuers shall not be required (A) to issue, to
              register the transfer of or to exchange any Notes during a period
              beginning at the opening of business 15 days before the day of any

              ending at the close of business on the day of selection, (B) to
              register the transfer of or to exchange any Note so selected for
              redemption in whole or in part, except the unredeemed portion of
              any Note being redeemed in part or (c) to register the transfer of
              or to exchange a Note between a record date and the next
              succeeding Interest Payment Date.

                  (vi) Prior to due presentment for the registration of a
              transfer of any Note, the Trustee, any Agent and the Issuers 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 interest and Liquidated Damages, if
              any, on such Notes and for all other purposes, and none of the
              Trustee, any Agent or the Issuers shall be affected by notice to
              the contrary.

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

                  (viii) All certifications, certificates and Opinions of

              be submitted by facsimile.

SECTION 2.07.     REPLACEMENT NOTES

         If any mutilated Note is surrendered to the Trustee or the Issuers and
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Note, the Issuers shall issue and the Trustee, upon receipt of an
Authentication Order, shall authenticate a replacement Note if the Trustee's
requirements are met. If required by the Trustee or the Issuers, an indemnity
bond must be supplied by the Holder that is sufficient in the judgment of the
Trustee and the Issuers to protect the Issuers, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Note is
replaced. The Issuers may charge for their expenses in replacing a Note.

         Every replacement Note is an additional obligation of the Issuers and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder.

SECTION 2.08.     OUTSTANDING NOTES.

         The 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 reductions in the interest in a Global Note effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note
does not cease to be outstanding 











                                       31
<PAGE>   40


because the Issuers or an Affiliate of the Issuers holds the Note; however,
Notes held by the Issuers or a Subsidiary of the Issuers shall not be deemed to
be outstanding for purposes of Section 3.07 hereof.

         If a Note is replaced pursuant to Section 2.07 hereof, 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 principal amount of any Note is considered paid under Section
4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

         If the Paying Agent (other than the Issuers, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Notes payable on that date, then on and after that date such
Notes shall be deemed to be no longer outstanding and shall cease to accrue
interest.

SECTION 2.09.     TREASURY NOTES.

         In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Issuer, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Issuer, shall be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Notes that the Trustee knows are so owned shall be so disregarded.

SECTION 2.10.     TEMPORARY NOTES

Until certificates representing Notes are ready for delivery, the Issuers may
prepare and the Trustee, upon receipt of an Authentication Order, shall
authenticate temporary Notes. Temporary Notes shall be substantially in the form
of certificated Notes but may have variations that the Issuers consider
appropriate for temporary Notes and as shall be reasonably acceptable to the
Trustee. Without unreasonable delay, the Issuers shall prepare and the Trustee
shall authenticate definitive Notes in exchange for temporary Notes.
         Holders of temporary Notes shall be entitled to all of the benefits of
this Indenture.

SECTION 2.11.     CANCELLATION.

         The Issuers at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall destroy
cancelled Notes (subject to the record retention requirement of the Exchange
Act). Certification of the destruction of all cancelled Notes shall be delivered
to the Issuers. The Issuers may not issue new Notes to replace Notes that it has
paid or that have been delivered to the Trustee for cancellation.

SECTION 2.12.     DEFAULTED INTEREST.

         If the Issuers default in a payment of interest on the Notes, it shall
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.01 hereof. The Issuers shall notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Note and the date
of the proposed payment. The Issuers shall fix or cause to be fixed each such
special record date and payment date, provided that no such special record date










                                       32
<PAGE>   41


shall be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Issuers (or, upon
the written request of the Issuers, the Trustee in the name and at the expense
of the Issuers) shall mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

                                   ARTICLE 3.
                            REDEMPTION AND PREPAYMENT

SECTION 3.01.     NOTICES TO TRUSTEE.

         If the Issuers elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 30 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Notes to be redeemed and (iv) the redemption price.

SECTION 3.02.     SELECTION OF NOTES TO BE REDEEMED

         If less than all of the Notes are to be redeemed at any time, selection
of Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed, or, if the Notes are not so listed, on a pro rata basis, by
lot or by such method as the Trustee shall deem fair and appropriate; provided
that no Notes of $1,000 or less shall be redeemed in part.

         The Trustee shall promptly notify the Issuers in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of
Notes selected shall be in amounts of $1,000 or whole multiples of $1,000;
except that if all of the Notes of a Holder are to be redeemed, the entire
outstanding amount of Notes held by such Holder, even if not a multiple of
$1,000, shall be redeemed. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption.

SECTION 3.03.     NOTICE OF REDEMPTION

         Subject to the provisions of Section 3.09 hereof, notices of redemption
shall be mailed by first class mail at least 30 but not more than 60 days before
the redemption date to each Holder of Notes to be redeemed at its registered
address. If any Note is to be redeemed in part only, the notice of redemption
that relates to such Note shall state the portion of the principal amount
thereof to be redeemed. A new Note in principal amount equal to the unredeemed
portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest ceases to
accrue on Notes or portions of them called for redemption.

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

          (a)     the redemption date;

          (b)     the redemption price;





                                       33
<PAGE>   42



          (c) if any Note is being redeemed in part, the portion of the
principal amount of such Note to be redeemed and that, after the redemption date
upon surrender of such Note, a new Note or Notes in principal amount equal to
the unredeemed portion shall be issued upon cancellation of the original Note;

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

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

          (f) that, unless the Issuers defaults in making such redemption
payment, interest on Notes called for redemption ceases to accrue on and after
the redemption date;

          (g) the paragraph of the Notes and/or Section of this Indenture
pursuant to which the Notes called for redemption are being redeemed; and

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

         At the Issuers' request, the Trustee shall give the notice of
redemption in the Issuers' name and at their expense; provided, however, that
the Issuers shall have delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

SECTION 3.04.     EFFECT OF NOTICE OF REDEMPTION

         Once notice of redemption is mailed in accordance with Section 3.03
hereof, Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price. A notice of redemption may not be
conditional.

SECTION 3.05.     DEPOSIT OF REDEMPTION PRICE

         One Business Day prior to the redemption date, the Issuers shall
deposit with the Trustee or with the Paying Agent money sufficient to pay the
redemption price of and accrued interest on all Notes to be redeemed on that
date. The Trustee or the Paying Agent shall promptly return to the Issuers any
money deposited with the Trustee or the Paying Agent by the Issuers in excess of
the amounts necessary to pay the redemption price of, and accrued interest on,
all Notes to be redeemed.

         If the Issuers comply with the provisions of the preceding paragraph,
on and after the redemption date, interest shall cease to accrue on the Notes or
the portions of Notes called for redemption. If a Note is redeemed on or after
an interest record date but on or prior to the related interest payment date,
then any accrued and unpaid interest shall be paid to the Person in whose name
such Note was registered at the close of business on such record date. If any
Note called for redemption shall not be so paid upon surrender for redemption
because of the failure of the Issuers to comply with the preceding paragraph,
interest shall be paid on the unpaid principal, from the redemption date until
such principal is paid, and to the extent lawful on any interest and Liquidated
Damages, if any, not paid on such unpaid principal, in each case at the rate
provided in the Notes and in Section 4.01 hereof.

         Upon surrender of a Note that is redeemed in part, the Issuers shall

the Holder at the expense of the Issuers a new Note equal in principal amount to
the unredeemed portion of the Note surrendered.

          (a) Except as provided below, the Notes will not be redeemable at the
Issuers' option prior to June 1, 2003. Thereafter, the Notes will be subject to

not less than 30 nor more than 60 days' notice, in cash at the redemption prices
(expressed as percentages of principal amount) set forth below, plus accrued and
unpaid interest and Liquidated Damages, if any, thereon to the applicable
redemption date, if redeemed during the twelve-month period beginning on June 1
of the years indicated below:

</TABLE>


         Notwithstanding the foregoing, on or prior to June 1, 2001, the Issuers
may redeem up to 35% of the aggregate principal amount of Notes ever issued
under this Indenture in cash at a redemption price of 109.875% of the principal

the occurrence of any such redemption; and provided further that such redemption
shall occur within 90 days of the date of the closing of any such Public Equity
Offering.

          In addition, at any time prior to June 1, 2003, the Issuers may, at
their option upon the occurrence of a Change of Control, redeem the Notes, in
whole but not in part, upon not less than 30 nor more than 60 days' prior notice
(but in no event may any such redemption occur more than 60 days after the
occurrence of such Change of Control), in cash at a redemption price equal to
(i) the present value of the sum of all the remaining interest (excluding
accrued and unpaid interest, if any), premium and principal payments that would
become due on the Notes as if the Notes were to remain outstanding and be
redeemed on June 1, 2003, computed using a discount rate equal to the Treasury
Rate plus 50 basis points, plus (ii) accrued and unpaid interest and Liquidated
Damages, if any, to the date of redemption.

          (b) Any redemption pursuant to this Section 3.07 shall be made
pursuant to the provisions of Section 3.01 through 3.06 hereof.

SECTION 3.08.     MANDATORY REDEMPTION.

         The Issuers are not required to make mandatory redemption of, or
sinking fund payments with respect to, the Notes.

SECTION 3.09.     OFFER TO PURCHASE BY APPLICATION OF EXCESS PROCEEDS.

         In the event that, pursuant to Section 4.10 hereof, the Issuers shall
be required to commence an offer to all Holders to purchase Notes (an "Asset
Sale Offer"), it shall follow the procedures specified below.

         The Asset Sale Offer shall remain open for a period of 20 Business Days
following its commencement and no longer, except to the extent that a longer
period is required by applicable law (the "Offer Period"). No later than five
Business Days after the termination of the Offer Period (the "Purchase Date"),
the Issuers shall purchase the principal amount of Notes required to be
purchased pursuant to Section 4.10 hereof (the "Offer Amount") or, if less than
the Offer Amount has been tendered, all Notes tendered in response to the Asset
Sale Offer. Payment for any Notes so purchased shall be made in the same manner
as interest payments are made.

         If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest shall
be paid to the Person in whose name a Note is registered at the close of
business on such record date, and no additional interest shall be payable to
Holders who tender Notes pursuant to the Asset Sale Offer.

         Upon the commencement of an Asset Sale Offer, the Issuers shall send,
by first class mail, a notice to the Trustee and each of the Holders, with a
copy to the Trustee. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Asset Sale
Offer. The Asset Sale Offer shall be made to all Holders. The notice, which
shall govern the terms of the Asset Sale Offer, shall state:

          (a) that the Asset Sale Offer is being made pursuant to this Section
3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer shall
remain open;

          (b) the Offer Amount, the purchase price and the Purchase Date;

          (c) that any Note not tendered or accepted for payment shall continue
to accrete or accrue interest;

          (d) that, unless the Issuers default in making such payment, any Note
accepted for payment pursuant to the Asset Sale Offer shall cease to accrete or
accrue interest after the Purchase Date;

          (e) that Holders electing to have a Note purchased pursuant to an
Asset Sale Offer may only elect to have all of such Note purchased and may not
elect to have only a portion of such Note purchased;

          (f) that Holders electing to have a Note purchased pursuant to any
Asset Sale Offer shall be required to surrender the Note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Note completed, or
transfer by book-entry transfer, to the Issuers, a depositary, if appointed by
the Issuers, or a Paying Agent at the address specified in the notice at least
three days before the Purchase Date;









                                       36
<PAGE>   45


          (g) that Holders shall be entitled to withdraw their election if the
Issuers, the depositary or the Paying Agent, as the case may be, receives, not
later than the expiration of the Offer Period, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing his election to have such Note purchased;

          (h) that, if the aggregate principal amount of Notes surrendered by
Holders exceeds the Offer Amount, the Issuers shall select the Notes to be
purchased on a pro rata basis (with such adjustments as may be deemed
appropriate by the Issuers so that only Notes in denominations of $1,000, or
integral multiples thereof, shall be purchased); and

          (i) that Holders whose Notes were purchased only in part shall be
issued new Notes equal in principal amount to the unpurchased portion of the
Notes surrendered (or transferred by book-entry transfer).

         On or before the Purchase Date, the Issuers shall, to the extent
lawful, accept for payment, on a pro rata basis to the extent necessary, the
Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale
Offer, or if less than the Offer Amount has been tendered, all Notes tendered,
and shall deliver to the Trustee an Officers' Certificate stating that such
Notes or portions thereof were accepted for payment by the Issuers in accordance
with the terms of this Section 3.09. The Issuers, the Depositary or the Paying
Agent, as the case may be, shall promptly (but in any case not later than five
days after the Purchase Date) mail or deliver to each tendering Holder an amount
equal to the purchase price of the Notes tendered by such Holder and accepted by
the Issuers for purchase, and the Issuers shall promptly issue a new Note, and
the Trustee, upon written request from the Issuers shall authenticate and mail
or deliver such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be
promptly mailed or delivered by the Issuers to the Holder thereof. The Issuers
shall publicly announce the results of the Asset Sale Offer on the Purchase
Date.

         Other than as specifically provided in this Section 3.09, any purchase

         The board of directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if such designation would not cause
a Default. For purposes of making such designation, all outstanding Investments

outstanding Investments will be deemed to constitute Restricted Investments in
an amount equal to the greater of (i) the net book value of such Investments at

at the time of such designation. Such designation will only be permitted if such
Restricted Investment would be permitted at such time and if such Restricted
Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

         The amount of (i) all Restricted Payments (other than cash) shall be
the fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment
and (ii) Qualified Proceeds (other than cash) shall be the fair market value on
the date of receipt thereof by the Company of such Qualified Proceeds. The fair
market value of any non-cash Restricted Payment shall be determined by the board
of directors of the Company whose resolution with respect thereto shall be
delivered to the Trustee. Not later than the date of making any Restricted
Payment, the Company shall deliver to the Trustee an Officers' Certificate
stating that such Restricted Payment is permitted and setting forth the basis
upon which the calculations required by this Section 4.07 were computed.

SECTION 4.08.    DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to (a)(i) pay dividends or make any other distributions to

(b) the New Credit Facility as in effect as of the date of this Indenture, and
any amendments, modifications, restatements,

rule, regulation or order, (e) any agreement or instrument of a Person acquired

such acquisition (except to the extent created in contemplation of such
acquisition), which encumbrance or restriction is not applicable to any Person,
or the properties or assets of any Person, other than the Person, or the
property or assets of the Person, so acquired, provided that, in the case of
Indebtedness, such Indebtedness was permitted by the terms of this Indenture to
be incurred, (f) customary non-assignment provisions in leases entered into in
the ordinary course of business and consistent with past practices, (g) purchase
money obligations for property acquired in the ordinary course of business that
impose restrictions of the nature described in clause (e) above on the property
so acquired, (h) contracts for the sale of assets, including, without
limitation, customary restrictions with respect to a Subsidiary pursuant to an
agreement that has been entered into for the sale or disposition of all or
substantially all of the Capital Stock or assets of such Subsidiary, (i)
Permitted Refinancing Indebtedness, provided that the restrictions contained in
the agreements governing such Permitted Refinancing Indebtedness are, in the
good faith judgment of the Company's board of directors, not materially less
favorable, taken as a whole, to the Holders of the Notes than those contained in
the agreements governing the Indebtedness being refinanced, (j) secured
Indebtedness otherwise permitted to be incurred pursuant to Sections 4.09 and
4.12 hereof that limit the right of the debtor to dispose of the assets securing
such Indebtedness, (k) restrictions on cash or other deposits or net worth
imposed by customers under contracts entered into in the ordinary course of
business, (l) other Indebtedness or Disqualified Stock of Restricted
Subsidiaries permitted to be incurred subsequent to the Issuance Date pursuant
to the provisions of Section 4.09 hereof, (m) customary provisions in joint
venture agreements and other similar agreements entered into in the ordinary
course of business, and (n) restrictions created in connection with any

          (a) the Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Indebtedness), (b) the Company will not, and will not permit any of its
Restricted Subsidiaries to, issue any shares of Disqualified Stock and (c) the
Company will not permit any of its Restricted Subsidiaries to issue any shares
of preferred stock; provided that the Company or any Restricted Subsidiary may
incur Indebtedness (including Acquired Indebtedness) or issue shares of
Disqualified Stock if the Fixed Charge Coverage Ratio for the Company's most
recently ended four full fiscal quarters for which internal financial statements
are available immediately preceding the date on which such additional
Indebtedness is incurred or such Disqualified Stock is issued would have been at
least 2.0 to 1, determined on a consolidated pro forma basis (including a pro
forma application of the net proceeds therefrom), as if the additional
Indebtedness had been incurred, or the Disqualified Stock had been issued, as
the case may be, at the beginning of such four-quarter period.

the Note Guarantees;

          (iv) the incurrence by the Company or any of its Restricted
Subsidiaries of Indebtedness represented by Capital Expenditure Indebtedness,
Capital Lease Obligations or purchase money obligations, in each case, incurred
for the purpose of financing all or any part of the purchase price or cost of
construction or improvement of property, plant or equipment used in the business
of the Company or such Restricted Subsidiary, in an aggregate principal amount
(or accreted value, as applicable) not to exceed $40.0 million outstanding after
giving effect to such incurrence;

          (v) Indebtedness arising from agreements of the Company or any
Restricted Subsidiary providing for indemnification, adjustment of purchase

with the disposition of any business, assets or a Subsidiary, other than
guarantees of Indebtedness incurred by any Person acquiring all or any portion
of such business, assets or Restricted Subsidiary for the purpose of financing
such acquisition; provided that (A) such Indebtedness is not reflected on the
balance sheet of the Company or any Restricted Subsidiary (contingent
obligations referred to in a footnote or footnotes to financial statements and
not otherwise reflected on the balance sheet will not be deemed to be reflected
on such balance sheet for purposes of this clause (A)) and (B) the maximum
assumable liability in respect of such Indebtedness shall at no time exceed the
gross proceeds including non-cash proceeds (the fair market value of such
non-cash proceeds being measured at the time received and without giving effect
to any subsequent changes in value) actually received by the Company and/or such
Restricted Subsidiary in connection with such disposition;

          (vi) the incurrence by the Company or any of its Restricted

          (vii) the incurrence by the Company or any of its Restricted
Subsidiaries of intercompany Indebtedness between or among the Company and/or
any of its Restricted Subsidiaries; provided that (i) if the Company is the
obligor on such Indebtedness, such Indebtedness is expressly subordinated to the
prior payment in full in cash of all Obligations with respect to the Notes and
(ii)(A) any subsequent issuance or transfer of Equity Interests that results in
any such Indebtedness being held by a Person other than the Company or a
Restricted Subsidiary thereof and (B) any sale or other transfer of any such
Indebtedness to a Person that is not either the Company or a Restricted
Subsidiary thereof shall be deemed, in each case, to constitute an incurrence of
such Indebtedness by the Company or such Restricted Subsidiary, as the case may
be, that was not permitted by this clause (vii);

          (viii) the incurrence by the Company or any of its Restricted
Subsidiaries of Hedging Obligations that are incurred for the purpose of fixing

that is permitted by the terms of this Indenture to be outstanding and (B)
exchange rate risk with respect to agreements or Indebtedness of such Person
payable denominated in a currency other than U.S. dollars, provided that such

                                       45
<PAGE>   54


obligor outstanding at any time other than as a result of fluctuations in
foreign currency exchange rates or interest rates or by reason of fees,
indemnities and compensation payable thereunder;

          (ix) the guarantee by the Company or any of its Restricted

Company that was permitted to be incurred by another provision of this covenant;

          (x) the incurrence by the Company or any of its Restricted

          (xi) obligations in respect of performance and surety bonds and
completion guarantees provided by the Company or any Restricted Subsidiary in
the ordinary course of business; and

          (xii) the incurrence by the Company or any of its Restricted
Subsidiaries of additional Indebtedness in an aggregate principal amount (or
accreted value, as applicable) outstanding after giving effect to such
incurrence, including all Permitted Refinancing Indebtedness incurred to refund,
refinance or replace any Indebtedness incurred pursuant to this clause (xii),
not to exceed $50.0 million.

         For purposes of determining compliance with this covenant, in the event
that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Indebtedness described in clauses (i) through (xii)
above or is entitled to be incurred pursuant to the first paragraph of this
covenant, the Company shall, in its sole discretion, classify such item of
Indebtedness in any manner that complies with this covenant and such item of
Indebtedness will be treated as having been incurred pursuant to only one of
such clauses or pursuant to the first paragraph hereof. In addition, the Company
may, at any time, change the classification of an item of Indebtedness (or any
portion thereof) to any other clause or to the first paragraph hereof provided
that the Company would be permitted to incur such item of Indebtedness (or such
portion thereof) pursuant to such other clause or the first paragraph hereof, as
the case may be, at such time of reclassification. Accrual of interest,
accretion or amortization of original issue discount will not be deemed to be an
incurrence of Indebtedness for purposes of this covenant.

         All Indebtedness under the New Credit Facility outstanding on the date
on which Notes are first issued and authenticated under this Indenture shall be
deemed to have been incurred on such date in reliance on the first paragraph of
Section 4.09 hereof.

SECTION 4.10.     ASSET SALES

         The Company shall not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless (a) the Company or such
Restricted Subsidiary, as the case may be, receives consideration at the time of
such Asset Sale at least equal to the fair market value (evidenced by a
resolution of the board of directors set forth in an Officers' Certificate
delivered to the Trustee) of the assets or Equity Interests issued or sold or
otherwise disposed of and (b) at least 75% of the consideration therefor
received by the Company or such Restricted Subsidiary is in the form of (i) cash
or Cash Equivalents or (ii) property or assets that are used or useful in a
Permitted Business, or the Capital Stock of any Person engaged in a Permitted
Business if, as a result of the acquisition by the Company or any Restricted
Subsidiary thereof, such Person becomes a Restricted Subsidiary; provided that
the amount of (x) any liabilities (as shown on the Company's or such Restricted
Subsidiary's most recent balance sheet), of the Company or any Restricted
Subsidiary (other than contingent liabilities and liabilities that are by their
terms subordinated to the Notes or any guarantee thereof) that are assumed by
the transferee of any such assets pursuant to a














                                       46
<PAGE>   55



customary novation agreement that releases the Company or such Restricted
Subsidiary from further liability, (y) any securities, notes or other
obligations received by the Company or any such Restricted Subsidiary from such
transferee that are contemporaneously (subject to ordinary settlement periods)
converted by the Company or such Restricted Subsidiary into cash or Cash
Equivalents (to the extent of the cash or Cash Equivalents received), and (z)
any Designated Noncash Consideration received by the Company or any of its
Restricted Subsidiaries in such Asset Sale having an aggregate fair market
value, taken together with all other Designated Noncash Consideration received
pursuant to this clause (z) that is at that time outstanding, not to exceed 15%
of Total Assets at the time of the receipt of such Designated Noncash
Consideration (with the fair market value of each item of Designated Noncash
Consideration being measured at the time received and without giving effect to
subsequent changes in value), shall be deemed to be cash for purposes of this
provision; and provided further that the 75% limitation referred to in clause
(b) above will not apply to any Asset Sale in which the cash or Cash Equivalents
portion of the consideration received therefrom, determined in accordance with
the foregoing proviso, is equal to or greater than what the after-tax proceeds
would have been had such Asset Sale complied with the aforementioned 75%
limitation.

         Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, the Company or any such Restricted Subsidiary shall apply such Net
Proceeds, at its option (or to the extent the Company is required to apply such
Net Proceeds pursuant to the terms of the New Credit Facility), to (a) repay or
purchase Senior Indebtedness or Pari Passu Indebtedness of the Company or any
Indebtedness of any Restricted Subsidiary, provided that, if the Company shall
so repay or purchase Pari Passu Indebtedness of the Company, it will equally and
ratably reduce Indebtedness under the Notes if the Notes are then redeemable,
or, if the Notes may not then be redeemed, the Company shall make an offer (in
accordance with the procedures set forth below for an Asset Sale Offer) to all
Holders of Notes to purchase at a purchase price equal to 100% of the principal
amount of the Notes, plus accrued and unpaid interest and Liquidated Damages, if
any, thereon to the date of purchase, the Notes that would otherwise be
redeemed, or (b) an investment in property, the making of a capital expenditure
or the acquisition of assets that are used or useful in a Permitted Business, or
Capital Stock of any Person primarily engaged in a Permitted Business if (i) as
a result of the acquisition by the Company or any Restricted Subsidiary thereof,
such Person becomes a Restricted Subsidiary or (ii) the Investment in such
Capital Stock is permitted by clause (f) of the definition of Permitted
Investments. Pending the final application of any such Net Proceeds, the Company
may temporarily reduce Indebtedness or otherwise invest such Net Proceeds in any
manner that is not prohibited by this Indenture. Any Net Proceeds from Asset
Sales that are not applied or invested as provided in the first sentence of this
paragraph will be deemed to constitute "Excess Proceeds." When the aggregate
amount of Excess Proceeds exceeds $15.0 million, the Company will be required to
make an offer to all Holders of Notes (an "Asset Sale Offer") to purchase the
maximum principal amount of Notes that may be purchased out of the Excess
Proceeds, at an offer price in cash in an amount equal to 100% of the principal
amount thereof, plus accrued and unpaid interest and Liquidated Damages, if any,
thereon to the date of purchase, in accordance with the procedures set forth in
this Indenture. To the extent that any Excess Proceeds remain after consummation
of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose
not otherwise prohibited by this Indenture. If the aggregate principal amount of
Notes surrendered by Holders thereof in connection with an Asset Sale Offer
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to be
purchased as set forth in Section 3.02 hereof. Upon completion of such offer to
purchase, the amount of Excess Proceeds shall be reset at zero.

         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 the Notes pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with the provisions of
this Indenture relating to such 












                                       47
<PAGE>   56



Asset Sale Offer, the Company will comply with the applicable securities laws
and regulations and shall not be deemed to have breached its obligations
described in this Indenture by virtue thereof.

SECTION 4.11.     TRANSACTIONS WITH AFFILIATES.

         The Company shall not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate of the Company (each of the foregoing, an "Affiliate
Transaction"), unless (a) such Affiliate Transaction is on terms that are no
less favorable to the Company or such Restricted Subsidiary than those that
would have been obtained in a comparable transaction by the Company or such
Restricted Subsidiary with an unrelated Person and (b) the Company delivers to
the Trustee, with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $7.5
million, either (i) a resolution of the board of directors set forth in an
Officers' Certificate certifying that such Affiliate Transaction complies with
clause (a) above and that such Affiliate Transaction has been approved by a
majority of the disinterested members of the board of directors or (ii) an
opinion as to the fairness to the Holders of such Affiliate Transaction from a
financial point of view issued by an accounting, appraisal or investment banking
firm of national standing.

         Notwithstanding the foregoing, the following items shall not be deemed
to be Affiliate Transactions: (a) customary directors' fees, indemnification or
similar arrangements or any employment agreement or other compensation plan or
arrangement entered into by the Company or any of its Restricted Subsidiaries in
the ordinary course of business (including ordinary course loans to employees
not to exceed (i) $5.0 million outstanding in the aggregate at any time and (ii)
$2.0 million to any one employee) and consistent with the past practice of the
Company or such Restricted Subsidiary; (b) transactions between or among the
Company and/or its Restricted Subsidiaries; (c) payments of customary fees by
the Company or any of its Restricted Subsidiaries to DLJMB and its Affiliates
made for any financial advisory, financing, underwriting or placement services
or in respect of other investment banking activities, including, without
limitation, in connection with acquisitions or divestitures which are approved
by a majority of the board of directors in good faith; (d) any agreement as in
effect on the date of this Indenture or any amendment thereto (so long as such
amendment is not disadvantageous to the Holders of the Notes in any material
respect) or any transaction contemplated thereby; (e) payments and transactions
in connection with the Merger, the New Credit Facility (including commitment,
syndication and arrangement fees payable thereunder) and the Offerings
(including underwriting discounts and commissions in connection therewith) and
the application of the proceeds thereof, and the payment of the fees and
expenses with respect thereto; (f) Restricted Payments that are permitted by
Section 4.07; (g) sales of accounts receivable, or participations therein, in
connection with any Receivables Facility; and (h) transactions pursuant to the
Management Loans.

SECTION 4.12.     LIENS.

         The Company shall not and will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, assume or
suffer to exist any Lien, other than a Permitted Lien, that secures obligations
under any Pari Passu Indebtedness or subordinated Indebtedness of the Company on
any asset or property now owned or hereafter acquired by the Company or any of
its Restricted Subsidiaries, or any income or profits therefrom or assign or
convey any right to receive income therefrom, unless the Notes are equally and
ratably secured with the obligations so secured until such time as such
obligations are no longer secured by a Lien; provided that, in any case
involving a Lien securing subordinated Indebtedness of 











                                       48
<PAGE>   57


the Company, such Lien is subordinated to the Lien securing the Notes to the
same extent that such subordinated Indebtedness is subordinated to the Notes.

SECTION 4.13.     CORPORATE EXISTENCE.

         Subject to Article 5 hereof, the Company shall do or cause to be done
all things necessary to preserve and keep in full force and effect (i) the
corporate, partnership or other existence of itself and each of its
Subsidiaries, in accordance with the respective organizational documents (as the
same may be amended from time to time) of the Company or any such Subsidiary and
(ii) 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 itself and any of its Subsidiaries, if the Board of
Directors 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 adverse in any material respect to the
Holders of the Notes.

SECTION 4.14.     OFFER TO REPURCHASE UPON CHANGE OF CONTROL.

          (a) Upon the occurrence of a Change of Control, each Holder of Notes
will have the right to require the Issuers to repurchase all or any part (equal
to $1,000 or an integral multiple thereof) of such Holder's Notes pursuant to
the offer described below (the "Change of Control Offer") at an offer price in
cash equal to 101% of the aggregate principal amount thereof, plus accrued and
unpaid interest and Liquidated Damages, if any, thereon to the date of
repurchase (the "Change of Control Payment"). Within 60 days following any
Change of Control, the Issuers will (or will cause the Trustee to) mail a notice
to each Holder describing the transaction or transactions that constitute the
Change of Control and offering to repurchase Notes on the date specified in such
notice, which date shall be no earlier than 30 days and no later than 60 days
from the date such notice is mailed (the "Change of Control Payment Date"),
pursuant to the procedures required by this Indenture and described in such
notice. The Issuers 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 the Notes as a result of a Change of Control. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of this Indenture relating to such Change of Control Offer, the
Issuers will comply with the applicable securities laws and regulations and
shall not be deemed to have breached their obligations described in this
Indenture by virtue thereof.

          On the Change of Control Payment Date, the Issuers will, to the extent
lawful, (a) accept for payment all Notes or portions thereof properly tendered
pursuant to the Change of Control Offer, (b) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all Notes or
portions thereof so tendered and (c) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officers' Certificate stating the
aggregate principal amount of Notes or portions thereof being purchased by the
Issuers. The Paying Agent will promptly mail to each Holder of Notes so tendered
the Change of Control Payment for such Notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book-entry) to each Holder
a new Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; provided that each such new Note will be in a principal
amount of $1,000 or an integral multiple thereof. Prior to complying with the
provisions of this covenant, but in any event within 90 days following a Change
of Control, the Issuers will either repay all outstanding Senior Indebtedness or
obtain the requisite consents, if any, under all agreements governing
outstanding Senior Indebtedness to permit the repurchase of Notes required by
this covenant. The Issuers 











                                       49
<PAGE>   58


will publicly announce the results of the Change of Control Offer on or as soon
as practicable after the Change of Control Payment Date.

          (b) Notwithstanding anything to the contrary in this Section 4.14, the
Issuers will not be required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements set forth in this
Indenture applicable to a Change of Control Offer made by the Issuers and
purchases all Notes validly tendered and not withdrawn under such Change of
Control Offer.

SECTION 4.15.     NO SENIOR SUBORDINATED INDEBTEDNESS.

          (a) the Company will not Incur any Indebtedness that is subordinate or
junior in right of payment to any Senior Indebtedness and senior in right of
payment to the Notes, and (b) no Guarantor will Incur any Indebtedness that is
subordinate or junior in right of payment to any Senior Indebtedness and senior
in any respect in right of payment to the Note Guarantees.

SECTION 4.16.     ACCOUNTS RECEIVABLE FACILITY.

         No Accounts Receivable Subsidiary will incur any Indebtedness if
immediately after giving effect to such incurrence the aggregate outstanding
Indebtedness of all Accounts Receivable Subsidiaries (excluding any Indebtedness
owed to the Company or any Restricted Subsidiary) would exceed $60.0 million.

SECTION 4.17.     LIMITATION ON SALE AND LEASEBACK TRANSACTIONS.

         The Company will not, and will not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; provided that
the Company or any Restricted Subsidiary may enter into a sale and leaseback
transaction if (a) the Company or such Restricted Subsidiary, as the case may
be, could have (i) incurred Indebtedness in an amount equal to the Attributable
Indebtedness relating to such sale and leaseback transaction pursuant to the
Fixed Charge Coverage Ratio test set forth in the first paragraph of Section
4.09 hereof and (ii) incurred a Lien to secure such Indebtedness pursuant to
Section 4.12 herein, (b) the gross cash proceeds of such sale and leaseback
transaction are at least equal to the fair market value (as determined in good
faith by the board of directors and set forth in an Officers' Certificate
delivered to the Trustee) of the property that is the subject of such sale and
leaseback transaction and (c) the transfer of assets in such sale and leaseback
transaction is permitted by, and the Company applies the proceeds of such
transaction in compliance with, Section 4.10 hereof.

SECTION 4.18.     RESTRICTIONS ON ACTIVITIES OF THERMADYNE CAPITAL

         Thermadyne Capital may not hold any assets, become liable for any
obligations or engage in any business activities; provided that Thermadyne
Capital may be a co-obligor with respect to Notes issued pursuant to this
Indenture and the Senior Indebtedness and engage in any activities directly
related or necessary in connection therewith.

SECTION 4.19.     PAYMENTS FOR CONSENT.

         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 this
Indenture or the Notes unless such consideration is offered to be paid or is
paid to all Holders of the Notes that 











                                       50
<PAGE>   59



consent, waive or agree to amend in the time frame set forth in the solicitation
documents relating to such consent, waiver or agreement.

SECTION 4.20.     ADDITIONAL NOTE GUARANTEES

         If any Restricted Subsidiary of the Company that is a Domestic
Subsidiary guarantees any Indebtedness under the New Credit Facility after the
date of this Indenture, then such Restricted Subsidiary shall become a Guarantor
by executing a Supplemental Indenture in the form attached hereto as Exhibit E
and deliver an Opinion of Counsel to the Trustee to the effect that such
Supplemental Indenture has been duly authorized, executed and delivered by such
Subsidiary and constitutes a valid and binding obligation of such Subsidiary,
enforceable against such Subsidiary in accordance with its terms (subject to
customary exceptions).

                                   ARTICLE 5.

SECTION 5.01.     MERGER, CONSOLIDATION, OR SALE OF ASSETS.

         The Company may not consolidate or merge with or into (whether or not
the Company is the surviving corporation), or sell, assign, transfer, convey or
otherwise dispose of all or substantially all of its properties or assets in one
or more related transactions, to another Person unless (a) the Company is the
surviving corporation or the Person formed by or surviving any such
consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, conveyance or other disposition shall have been made is a
corporation organized or existing under the laws of the United States, any state
thereof or the District of Columbia, (b) the Person formed by or surviving any
such consolidation or merger (if other than the Company) or the Person to which
such sale, assignment, transfer, conveyance or other disposition shall have been
made assumes all the obligations of the Company under the Registration Rights
Agreement, the Notes and this Indenture pursuant to a supplemental indenture in
a form reasonably satisfactory to the Trustee, (c) immediately after such
transaction no Default or Event of Default exists and (d) the Company or the
Person formed by or surviving any such consolidation or merger (if other than
the Company), or to which such sale, assignment, transfer, conveyance or other

after giving pro forma effect thereto as if such transaction had occurred at the
beginning of the applicable four-quarter period, be permitted to incur at least
$1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
test set forth in the first paragraph of Section 4.09 hereof or (ii) would
(together with its Restricted Subsidiaries) have a higher Fixed Charge Coverage
Ratio immediately after such transaction (after giving pro forma effect thereto
as if such transaction had occurred at the beginning of the applicable
four-quarter period) than the Fixed Charge Coverage Ratio of the Company and its
Restricted Subsidiaries immediately prior to such transaction. The foregoing
clause (d) will not prohibit (a) a merger between the Company and a Wholly Owned
Subsidiary of Holdings created for the purpose of holding the Capital Stock of
the Company, (b) a merger between the Company and a Wholly Owned Restricted
Subsidiary or (c) a merger between the Company and an Affiliate incorporated
solely for the purpose of reincorporating the Company in another State of the
United States so long as, in each case, the amount of Indebtedness of the
Company and its Restricted Subsidiaries is not increased thereby. The Company
will not lease all or substantially all of its assets to any Person.

SECTION 5.02.     SUCCESSOR CORPORATION SUBSTITUTED.

         Upon any consolidation or merger, or any sale, assignment, transfer,

formed by such consolidation or into or with which the Company is 











                                       51
<PAGE>   60


merged or to which such sale, assignment, transfer, lease, conveyance or other
disposition is made shall succeed to, and be substituted for (so that from and
after the date of such consolidation, merger, sale, lease, conveyance or other
disposition, the provisions of this Indenture referring to the "Company" shall
refer instead to the successor corporation and not to the Company), and may
exercise every right and power of the Company under this Indenture with the same
effect as if such successor Person had been named as the Company herein;
provided, however, that the predecessor Company shall not be relieved from the
obligation to pay the principal of and interest or Liquidated Damages, if any,
on the Notes except in the case of a sale of all of the Company's assets that
meets the requirements of Section 5.01 hereof.

                              DEFAULTS AND REMEDIES


SECTION 6.01.     EVENTS OF DEFAULT.

         Each of the following constitutes an Event of Default:

          (a) default for 30 days in the payment when due of interest on, or

Article 10 hereof);

          (b) default in payment when due of the principal of or premium, if
any, on the Notes (whether or not prohibited by Article 10 hereof);
          (c) failure by the Company or any of its Restricted Subsidiaries for
30 days after receipt of notice from the Trustee or Holders of at least 25% in
principal amount of the Notes then outstanding to comply with Sections 4.07,
4.09, 4.10, 4.14 or Article 5 hereof;

          (d) failure by the Company for 60 days after notice from the Trustee

to comply with any of its other agreements in this Indenture or the Notes;

          (e) default under any mortgage, indenture or instrument under which
there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Company or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Restricted Subsidiaries), whether such Indebtedness or guarantee now exists, or
is created after the date of this Indenture, which default (i) is caused by a
failure to pay Indebtedness at its stated final maturity (after giving effect to

              constitute a Significant Subsidiary;

and the order or decree remains unstayed and in effect for 60 consecutive days.

SECTION 6.02.     ACCELERATION.

         If any Event of Default (other than an Event of Default specified in
clause (h) or (i) of Section 6.01 hereof with respect to the Company, any
Restricted Subsidiaries that is a Significant Subsidiary or any group of
Restricted Subsidiaries that, taken as a whole, would constitute a Significant
Subsidiary) occurs and is continuing, the Trustee or the Holders of at least 25%
in principal amount of the then outstanding Notes may declare all the Notes to
be due and payable immediately; provided, that so long as any Indebtedness
permitted to be incurred pursuant to the New Credit Facility shall be
outstanding, such acceleration shall not be effective until the earlier of (i)
an acceleration under any such Indebtedness under the New Credit Facility or
(ii) five Business Days after receipt by the Issuers and the administrative
agent under the New Credit Facility of written notice of such acceleration. Upon
any such declaration, the Notes shall become due and payable immediately.
Notwithstanding the foregoing, if an Event of Default specified in clause (h) or
(i) of Section 6.01 hereof occurs with respect to the Company, any of its
Restricted Subsidiaries that is a Significant Subsidiary or any group of
Restricted Subsidiaries 








                                       53
<PAGE>   62


that, taken as a whole, would constitute a Significant Subsidiary, all
outstanding Notes shall be due and payable immediately without further action or
notice. The Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may on behalf of all of the
Holders rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal, interest or premium or Liquidated Damages, if
any, that has become due solely because of the acceleration) have been cured or
waived, provided that, in the event of a declaration of acceleration of the
Notes because an Event of Default has occurred and is continuing as a result of
the acceleration of any Indebtedness described in clause (e) of Section 6.01
hereof, the declaration of acceleration of the Notes shall be automatically
annulled if the holders of any Indebtedness described in clause (e) of Section
6.01 hereof have rescinded the declaration of acceleration in respect of such
Indebtedness within 30 days of the date of such declaration and if (i) the
annulment of the acceleration of the Notes would not conflict with any judgment
or decree of a court of competent jurisdiction and (ii) all existing Events of
Default, except non-payment of principal or interest on the Notes that became
due solely because of the acceleration of the Notes, have been cured or waived.

SECTION 6.03.     OTHER REMEDIES.

         If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal, premium, if any, and
interest and Liquidated Damages, if any, on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Note 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. All remedies are
cumulative to the extent permitted by law.

SECTION 6.04.     WAIVER OF PAST DEFAULTS.

         Holders of not less than a majority in aggregate principal amount of
the then outstanding Notes by notice to the Trustee may on behalf of the Holders
of all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium and Liquidated Damages, if any, or interest
on, the Notes (including in connection with an offer to purchase) (provided,
however, that the Holders of a majority in aggregate principal amount of the
then outstanding Notes may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration).
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon.

SECTION 6.05.     CONTROL BY MAJORITY.

         Holders of a majority in principal amount of the then outstanding Notes
may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability.

SECTION 6.06.     LIMITATION ON SUITS.

         A Holder of a Note may pursue a remedy with respect to this Indenture
or the Notes only if:

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

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

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

          (d) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer and, if requested, the provision of
indemnity; and

          (e) during such 60-day period the Holders of a majority in principal
amount of the then outstanding Notes do not give the Trustee a direction
inconsistent with the request.

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

         Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium and Liquidated
Damages, if any, and interest on the Note, on or after the respective due dates
expressed in the Note (including in connection with an offer to purchase), or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

SECTION 6.08.     COLLECTION SUIT BY TRUSTEE.

         If an Event of Default specified in Section 6.01(a) or (b) occurs and
is continuing, the Trustee is authorized to recover judgment in its own name and
as trustee of an express trust against the Issuers for the whole amount of
principal of, premium and Liquidated Damages, if any, and interest remaining
unpaid on the Notes and interest and Liquidated Damages, if any, on overdue
principal and, to the extent lawful, interest and such further amount as shall
be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

SECTION 6.09.     TRUSTEE MAY FILE PROOFS OF CLAIM.

         The Trustee is authorized to file such proofs of claim and other papers
or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Issuers
(or any other obligor upon the Notes), its creditors or its property and shall
be entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims 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 to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and

advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.07 hereof out of the estate in any such proceeding,
shall be denied for any reason, payment of the same shall be secured by a Lien
on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties that the Holders may be entitled to receive in
such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. 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, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

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 a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.

SECTION 7.01.     DUTIES OF TRUSTEE.

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

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

                  (i) the duties of the Trustee shall be determined solely by
              the express provisions of this Indenture and the Trustee need
              perform only those duties that are specifically set forth in this

              shall be read into this Indenture against the Trustee; and

                  (ii) in the absence of bad faith on its part, the Trustee may
              conclusively rely, as to the truth of the statements and the
              correctness of the opinions expressed therein, upon certificates
              or opinions furnished to the Trustee and conforming to the
              requirements of this Indenture. However, the Trustee shall examine
              the certificates and opinions to determine whether or not they
              conform to the requirements of this Indenture.

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

              of this Section;

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

                  (iii) the Trustee shall not be liable with respect to any
              action it takes or omits to take in good faith in accordance with
              a direction received by it pursuant to Section 6.05 hereof.

paragraphs (a), (b), (c), (e) and (f) of this Section and Section 7.02.

          (e)     No provision of this Indenture shall require the Trustee to 
expend or risk its own funds or incur any liability. The Trustee shall be under
no obligation to exercise any of its rights and powers under this Indenture at
the request of any Holders, unless such Holder shall have offered to the Trustee
security and indemnity satisfactory to it against any loss, liability or
expense.

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

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

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

any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon.

be responsible for the misconduct or negligence of any agent appointed with due

demand, request, direction or notice from the Issuers shall be sufficient if
signed by an Officer of the Issuers.

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

          (g) Except with respect to Section 4.01 hereof, the Trustee shall have
no duty to inquire as to the performance of the Issuers' covenants in Article 4
hereof. In addition, the Trustee shall not be deemed to have knowledge of any
Default or Event of Default except (i) any Event of Default occurring pursuant
to Sections 6.01(a), 6.01(b) and 4.01 or (ii) any Default or Event of Default of
which the Trustee shall have received written notification or obtained actual
knowledge.

facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the Trustee
may, in its discretion, make such further inquiry or investigation into such
facts or matters as it may see fit and if the Trustee shall determine to make
such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Issuers personally or by agent or attorney.

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 Issuers or any
Affiliate of the Issuers with the same rights it would have if it were not
Trustee. However, in the event that the Trustee acquires any conflicting
interest it must eliminate such conflict within 90 days, apply to the Commission
for permission to continue as trustee or resign. Any Agent may do the same with
like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11
hereof.

accountable for the Issuers' use of the proceeds from the Notes or any money
paid to the Issuers or upon the Issuers' direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

SECTION 7.05.     NOTICE OF DEFAULTS.

         If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case
of a Default or Event of Default in payment of principal of, premium, if any, or
interest or Liquidated Damages, if any, on any Note, the Trustee may withhold
the notice if and so long as a committee of its Responsible Officers in good
faith determines that withholding the notice is in the interests of the Holders
of the Notes.

SECTION 7.06.     REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES.

         Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, and for so long as Notes remain outstanding, the
Trustee shall mail to the Holders of the Notes a brief report dated as of such
reporting date that complies with TIA ss. 313(a) (but if no event described in
TIA ss. 313(a) has occurred within the twelve months preceding the reporting
date, no report need be transmitted). The Trustee also shall comply with TIA ss.
(b)(2). The Trustee shall also transmit by mail all reports as required by TIA
ss. 313(c).

         A copy of each report at the time of its mailing to the Holders of

stock exchange on which the Notes are listed in accordance with TIA ss. 313(d).
The Issuers shall promptly notify the Trustee when the Notes are listed on any
stock exchange.

SECTION 7.07.     COMPENSATION AND INDEMNITY.

         The Issuers shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Issuers shall reimburse the Trustee promptly
upon request for all reasonable disbursements, advances and expenses incurred or
made by it in addition to the compensation for its services. Such expenses shall
include the reasonable compensation, disbursements and expenses of the Trustee's
agents and counsel.

         The Issuers shall indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the
costs and expenses of enforcing this Indenture against the Issuers (including
this Section 7.07) and defending itself against any claim (whether asserted by
the Issuers or any Holder or any other person) or liability in connection with

the extent any such loss, liability or expense may be attributable to its
negligence or bad faith. The Trustee shall notify the Issuers promptly of any
claim for which it may seek 











                                       59

indemnity. Failure by the Trustee to so notify the Issuers shall not relieve the
Issuers of its obligations hereunder. The Issuers shall defend the claim and the
Trustee shall cooperate in the defense. The Trustee may have separate counsel
and the Issuers shall pay the reasonable fees and expenses of such counsel. The
Issuers need not pay for any settlement made without its consent, which consent

interest on particular Notes. Such Lien shall survive the satisfaction and
discharge of this Indenture.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(h) or (i) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

         The Trustee shall comply with the provisions of TIA ss. 313(b)(2) to
the extent applicable.

SECTION 7.08.     REPLACEMENT OF TRUSTEE.

         A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

         The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Issuers. The Holders of Notes of a
majority in principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Issuers in writing. The Issuers may
remove the Trustee if:

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

          (b) the Trustee is adjudged a bankrupt or an insolvent or an order for
relief is entered with respect to the Trustee under any Bankruptcy Law;

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Issuers shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Issuers.

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

         If the Trustee, after written request by any Holder of a Note who has
been a Holder of a Note for at least six months, fails to comply with Section
7.10, such Holder of a Note may petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee.

appointment to the retiring Trustee and to the Issuers. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Notes. The retiring Trustee shall promptly transfer
all property held by it as Trustee to the successor Trustee, provided all sums
owing to the Trustee hereunder have been paid and subject to the Lien provided
for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant
to this Section 7.08, the Issuers' obligations under Section 7.07 hereof shall
continue for the benefit of the retiring Trustee.

SECTION 7.09.     SUCCESSOR TRUSTEE BY MERGER, ETC.

         If the Trustee consolidates, merges or converts into, or transfers all
or substantially all of its corporate trust business to, another corporation,
the successor corporation without any further act shall be the successor
Trustee.

SECTION 7.10.     ELIGIBILITY; DISQUALIFICATION.

         There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $100 million
as set forth in its most recent published annual report of condition.

         This Indenture shall always have a Trustee who satisfies the

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

         The Issuers may, at the option of their respective Board of Directors

SECTION 8.02.     LEGAL DEFEASANCE AND DISCHARGE.

         Upon the Issuers' exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Issuers shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be deemed to have been
discharged from their obligations with respect to all outstanding Notes on the
date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, Legal Defeasance means that the Issuers shall be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes, which shall thereafter be deemed to be "outstanding" only for
the purposes of Section 8.05 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all its other
obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Issuers, shall execute proper instruments
acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder:

          (a) the rights of Holders of outstanding Notes to receive payments in
respect of the principal of, premium, if any, and interest and Liquidated
Damages, if any, on such Notes when such payments are due from the trust
referred to below,

          (b) the Issuers' obligations with respect to the Notes concerning
issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or
stolen Notes and the maintenance of an office or agency for payment and money
for security payments held in trust,

          (c) the rights, powers, trusts, duties and immunities of the Trustee,
and the Issuers' obligations in connection therewith and

          (d) the Legal Defeasance provisions of this Indenture.

SECTION 8.03.     COVENANT DEFEASANCE.

         Upon the Issuers' exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Issuers shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from its
obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10,
4.11, 4.12, 4.14, 4.15, 4.16, 4.17, 4.19 and 4.20 hereof with respect to the
outstanding Notes on and after the date the conditions set forth in Section 8.04
are satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall
thereafter be deemed not "outstanding" for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"outstanding" for all other purposes hereunder (it being understood that such
Notes shall not be deemed outstanding for accounting purposes). For this
purpose, Covenant Defeasance means that, with respect to the outstanding Notes,
the Issuers may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such
covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 6.01 hereof, but,
except as specified above, the remainder of this Indenture and such Notes shall
be unaffected thereby. In addition, upon the Issuers' exercise under Section
8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, Sections
6.01(d) through 6.01(f) hereof shall not constitute Events of Default.

SECTION 8.04.     CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

         The following shall be the conditions to the application of either
Section 8.02 or 8.03 hereof to the outstanding Notes:

         In order to exercise either Legal Defeasance or Covenant Defeasance,

          (a) the Issuers must irrevocably deposit with the Trustee, in trust,
for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of, premium, if any, and interest and
Liquidated Damages, if any, on the outstanding Notes on the stated maturity or
on the applicable redemption date, as the case may be, and the Issuers must
specify whether the Notes are being defeased to maturity or to a particular
redemption date,

          (b) in the case of Legal Defeasance, the Issuers shall have delivered
to the Trustee an Opinion of Counsel in the United States reasonably acceptable
to the Trustee confirming that (i) the Issuers has received from, or there has
been published by, the Internal Revenue Service a ruling or (ii) since the date
of this Indenture, there has been a change in the applicable federal income tax
law, in either case to the effect that, and based thereon such Opinion of
Counsel shall confirm that, subject to customary assumptions and exclusions, the
Holders of the outstanding Notes will not recognize income, gain or loss for
federal income tax purposes as a result of such Legal Defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such Legal Defeasance had not
occurred,

          (c) in the case of Covenant Defeasance, the Issuers shall have
delivered to the Trustee an Opinion of Counsel in the United States reasonably
acceptable to the Trustee confirming that, subject to customary assumptions and
exclusions, the Holders of the outstanding Notes will not recognize income, gain
or loss for federal income tax purposes as a result of such Covenant Defeasance
and will be subject to federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred,

          (d) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit) or, insofar
as Events of Default from bankruptcy or insolvency events are concerned, at any
time in the period ending on the 123rd day after the date of deposit,

          (e) such Legal Defeasance or Covenant Defeasance will not result in a
breach or violation of, or constitute a default under, any material agreement or
instrument (other than this Indenture) to which the Company or any of its
Subsidiaries is a party or by which the Company or any of its Subsidiaries is
bound,

          (f) the Issuers must have delivered to the Trustee an Opinion of
Counsel to the effect that, subject to customary assumptions and exclusions,
after the 123rd day following the deposit, the trust funds will not be subject
to the effect of Section 547 of the United States Bankruptcy Code or any
analogous New York State law provision or any other applicable federal or New
York bankruptcy, insolvency, reorganization or similar laws affecting creditors'
rights generally,

          (g) the Issuers must deliver to the Trustee an Officers' Certificate
stating that the deposit was not made by the Issuers with the intent of
preferring the Holders of Notes over the other creditors of the Issuers with the
intent of defeating, hindering, delaying or defrauding creditors of the Issuers
or others, and










                                       63
<PAGE>   72


          (h) the Issuers must deliver to the Trustee an Officers' Certificate
and an Opinion of Counsel (which opinion may be subject to customary assumptions
and exclusions), each stating that all conditions precedent provided for
relating to the Legal Defeasance or the Covenant Defeasance have been complied
with.

SECTION 8.05.     DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN TRUST;
OTHER  MISCELLANEOUS PROVISIONS.

         Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Issuers acting as Paying Agent) as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium, if any, and interest and
Liquidated Damages, if any, but such money need not be segregated from other
funds except to the extent required by law.

         The Issuers shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Notes.

         Anything in this Article Eight to the contrary notwithstanding, the
Trustee shall deliver or pay to the Issuers from time to time upon the request
of the Issuers any money or non-callable Government Securities held by it as
provided in Section 8.04 hereof which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under
Section 8.04(a) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

SECTION 8.06.     REPAYMENT TO ISSUERS.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Issuers, in trust for the payment of the principal of, premium, if any,
or interest or Liquidated Damages, if any, on any Note and remaining unclaimed
for two years after such principal, and premium, if any, or interest or
Liquidated Damages, if any, has become due and payable shall be paid to the
Issuers on its request or (if then held by the Issuers) shall be discharged from
such trust; and the Holder of such Note shall thereafter, as a secured creditor,
look only to the Issuers for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Issuers as trustees thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Issuers cause to be published once, in the New York
Times and The Wall Street Journal (national edition), notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such notification or publication, any
unclaimed balance of such money then remaining will be repaid to the Issuers.

<PAGE>   73



SECTION 8.07.     REINSTATEMENT.

         If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02 or
8.03 hereof, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Issuers' obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.02 or 8.03
hereof, as the case may be; provided, however, that, if the Issuers make any
payment of principal of, premium, if any, or interest or Liquidated Damages, if
any, on any Note following the reinstatement of their obligations, the Issuers
shall be subrogated to the rights of the Holders of such Notes to receive such
payment from the money held by the Trustee or Paying Agent.

                                   ARTICLE 9.
                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01.     WITHOUT CONSENT OF HOLDERS OF NOTES.

         Notwithstanding Section 9.02 of this Indenture, the Issuers, the
Guarantors and the Trustee may amend or supplement this Indenture, the Note
Guarantees or the Notes without the consent of any Holder of a Note:

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

          (b) to provide for uncertificated Notes in addition to or in place of
certificated Notes or to alter the provisions of Article 2 hereof (including the
related definitions) in a manner that does not materially adversely affect any
Holder;

          (c) to provide for the assumption of the Issuers' or Guarantor's
obligations to the Holders of the Notes by a successor to the Issuers or a
Guarantor pursuant to Article 5 or Article 11 hereof;

          (d) to make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal
rights hereunder of any Holder of the Note;

          (e) to comply with requirements of the Commission in order to effect
or maintain the qualification of this Indenture under the TIA;

          (f) to provide for the issuance of Additional Notes in accordance with
the limitations set forth in this Indenture as of the date hereof; or

          (g) to allow any Guarantor to execute a supplemental indenture and/or
a Note Guarantee with respect to the Notes.

         Upon the request of the Issuers accompanied by a resolution of their
Board of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee shall join with the Issuers in the execution of any
amended or supplemental Indenture authorized or permitted by the terms of this
Indenture and to make any further appropriate agreements and stipulations that
may be therein contained, but the Trustee shall not be obligated to enter into
such amended or supplemental Indenture that affects its own rights, duties or
immunities under this Indenture or otherwise.











                                       65
<PAGE>   74


SECTION 9.02.     WITH CONSENT OF HOLDERS OF NOTES.

         Except as provided below in this Section 9.02, the Issuers and the
Trustee may amend or supplement this Indenture (including Section 3.09, 4.10 and
4.15 hereof), the Note Guarantees and the Notes may be amended or supplemented
with the consent of the Holders of at least a majority in principal amount of
the Notes (including Additional Notes, if any) then outstanding voting as a
single class (including consents obtained in connection with a tender offer or
exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04
and 6.07 hereof, any existing Default or Event of Default (other than a Default
or Event of Default in the payment of the principal of, premium, if any, or
interest or Liquidated Damages, if any, on the Notes, except a payment default
resulting from an acceleration that has been rescinded) or compliance with any
provision of this Indenture, the Note Guarantees or the Notes may be waived with
the consent of the Holders of a majority in principal amount of the then
outstanding Notes (including Additional Notes, if any) voting as a single class
(including consents obtained in connection with a tender offer or exchange offer
for, or purchase of, the Notes). Notwithstanding the foregoing, any (i)
amendment to or waiver of Sections 4.10 and 4.14 hereof, and (ii) amendment to
Article 10 herein will require the consent of the Holders of at least two-thirds
in aggregate principal amount of the Notes then outstanding if such amendment
would materially adversely affect the rights of Holders of Notes. Section 2.08
hereof shall determine which Notes are considered to be "outstanding" for
purposes of this Section 9.02.

         Upon the request of the Issuers accompanied by a resolution of their
respective Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon the filing with the Trustee of evidence
satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid,
and upon receipt by the Trustee of the documents described in Section 7.02
hereof, the Trustee shall join with the Issuers in the execution of such amended
or supplemental Indenture unless such amended or supplemental Indenture directly
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such amended or supplemental Indenture.

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

         After an amendment, supplement or waiver under this Section becomes
effective, the Issuers shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Issuers to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Notes (including Additional Notes,
if any) then outstanding voting as a single class may waive compliance in a
particular instance by the Issuers with any provision of this Indenture or the
Notes. However, without the consent of each Holder affected, an amendment or
waiver under this Section 9.02 may not (with respect to any Notes held by a
non-consenting Holder):

          (a) reduce the principal amount of Notes whose Holders must consent to
an amendment, supplement or waiver,

          (b) reduce the principal of or change the fixed maturity of any Note
or alter the provisions with respect to the redemption of the Notes (other than
Sections 4.10 and 4.14 hereof,










                                       66
<PAGE>   75



          (c) reduce the rate of or change the time for payment of interest on
any Note,

          (d) waive a Default or Event of Default in the payment of principal of
or premium, if any, or interest or Liquidated Damages, if any, on the Notes
(except a rescission of acceleration of the Notes by the Holders of at least a
majority in aggregate principal amount of the Notes and a waiver of the payment
default that resulted from such acceleration),

          (e) make any Note payable in money other than that stated in the
Notes,

          (f) make any change in the provisions of this Indenture relating to
waivers of past Defaults,

          (g) waive a redemption payment with respect to any Note (other than
Sections 4.10 and 4.14 hereof,

          (h) release any Guarantor from its obligations under its Note
Guarantee or the Indenture, except in accordance with the terms of the
Indenture; or

          (i) make any change in the foregoing amendment and waiver provisions.

SECTION 9.03.     COMPLIANCE WITH TRUST INDENTURE ACT.

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

SECTION 9.04.     REVOCATION AND EFFECT OF CONSENTS.

         Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note, even if notation of the consent is not
made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

SECTION 9.05.     NOTATION ON OR EXCHANGE OF NOTES.

         The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Issuers in
exchange for all Notes may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

         Failure to make the appropriate notation or issue a new Note shall not
affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.06.     TRUSTEE TO SIGN AMENDMENTS, ETC.

         The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article Nine if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Issuers
may not sign an amendment or supplemental Indenture until their respective Board
of Directors approves it. In executing any amended or supplemental indenture,
the 













                                       67
<PAGE>   76


Trustee shall be entitled to receive and (subject to Section 7.01 hereof)
shall be fully protected in relying upon, in addition to the documents required
by Section 11.04 hereof, an Officer's Certificate and an Opinion of Counsel
stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.

                                   ARTICLE 10.

to the extent and in the manner set forth in this Article 10, to the prior
payment in full in cash or cash equivalents of all Senior Indebtedness, whether
outstanding on the date of this Indenture or thereafter incurred and that the
subordination is for the benefit of the holders of Senior Indebtedness. The
provisions of this Article 10 shall constitute a continuing offer to all Persons
that, in reliance upon such provisions, become holders of, or continue to hold
Senior Indebtedness, and they or each of them may enforce the rights of holders
of Senior Indebtedness hereunder, subject to the terms and provisions hereof.

SECTION 10.02.    CERTAIN DEFINITIONS.

         "Permitted Junior Securities" means Equity Interests in the Issuers or
debt securities of the Issuers that are subordinated to all Senior Indebtedness

         "Representative" means the indenture trustee or other trustee, agent or
representative for any Senior Indebtedness.

Hedging Obligations payable to a lender or an Affiliate thereof or to a Person
that was a lender or an Affiliate thereof at the time the contract was entered

Indebtedness, unless the instrument under which such Indebtedness is incurred
expressly provides that it is subordinated in right of payment to any other

other transfer of assets by or on behalf of any Issuer (including, without
limitation, a redemption, repurchase or other acquisition of the Notes) from any
source, of any kind or character, whether in cash, securities or other property,
by set-off or otherwise.

SECTION 10.03.    LIQUIDATION; DISSOLUTION; BANKRUPTCY.

         Upon any distribution to creditors of the Issuers in a liquidation or
dissolution of the Issuers or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Issuers or their property, an

to receive payment in full in cash or cash equivalents of all Obligations due in
respect of such Senior Indebtedness (including interest after the commencement

of Notes may receive and retain Permitted Junior Securities and payments and
other distributions made from the trust described in Section 8.04 hereof), and
(b) until all Obligations with respect to Senior Indebtedness are paid in full

Junior Securities and payments and other distributions made from the trust
described Section 8.04 hereof) as their interests appear.

SECTION 10.04.    DEFAULT ON DESIGNATED SENIOR INDEBTEDNESS.

         The Issuers may not make any payment or distribution to the Trustee or
any Holder upon or in respect of the Subordinated Note Obligations (except in
Permitted Junior Securities or from the trust described in Section 8.04 hereof)
until all principal and other obligations with respect to Senior Indebtedness
have been paid in full in cash or cash equivalents, if

          (a) a default in the payment of the principal (including reimbursement
obligations in respect of letters of credit) of, premium, if any, or interest on
or commitment fees relating to, Designated Senior Indebtedness occurs and is
continuing beyond any applicable period of grace in the agreement, indenture or
other document governing such Designated Senior Indebtedness or

          (b) any other default occurs and is continuing with respect to
Designated Senior Indebtedness that permits holders of the Designated Senior
Indebtedness as to which such default relates to accelerate its maturity and the
Trustee receives a notice of such default (a "Payment Blockage Notice") from the
Issuers or the holders of any Designated Senior Indebtedness (or their
Representative).

         Payments on the Notes may and shall be resumed (a) in the case of a
payment default, upon the date on which such default is cured or waived and (b)
in case of a nonpayment default, the earlier of the date on which such
nonpayment default is cured or waived or 179 days after the date on which the
applicable Payment Blockage Notice is received, unless the maturity of any
Designated Senior 










                                       69
<PAGE>   78


Indebtedness has been accelerated. No new period of payment blockage may be
commenced unless and until 360 days have elapsed since the effectiveness of the
immediately prior Payment Blockage Notice. No nonpayment default that existed or
was continuing on the date of delivery of any Payment Blockage Notice to the
Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice
unless such default shall have been waived or cured for a period of not less
than 90 days.

SECTION 10.05.    ACCELERATION OF SECURITIES.

         If payment of the Notes is accelerated because of an Event of Default,
the Issuers shall promptly notify holders of Senior Indebtedness of the
acceleration.

SECTION 10.06.    WHEN DISTRIBUTION MUST BE PAID OVER.

         In the event that the Trustee or any Holder receives any payment of any
Subordinated Note Obligations at a time when the Trustee or such Holder, as
applicable, has actual knowledge that such payment is prohibited by Section
10.03 or 10.04 hereof, such payment shall be held by the Trustee or such Holder,
in trust for the benefit of, and shall be paid forthwith over and delivered,
upon written request, to, the holders of Senior Indebtedness as their interests
may appear or their Representative under the indenture or other agreement (if
any) pursuant to which Senior Indebtedness may have been issued, as their
respective interests may appear, for application to the payment of all
Obligations with respect to Senior Indebtedness remaining unpaid to the extent
necessary to pay such Obligations in full in accordance with their terms, after
giving effect to any concurrent payment or distribution to or for the holders of
Senior Indebtedness.

         With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform only such obligations on the part of the Trustee as are
specifically set forth in this Article 10, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness, and shall not be
liable to any such holders if the Trustee shall pay over or distribute to or on
behalf of Holders or the Issuers or any other Person money or assets to which
any holders of Senior Indebtedness shall be entitled by virtue of this Article
10, except if such payment is made as a result of the willful misconduct or
gross negligence of the Trustee.

SECTION 10.07.    NOTICE BY ISSUERS.

         The Issuers shall promptly notify the Trustee and the Paying Agent of
any facts known to the Issuers that would cause a payment of any Obligations
with respect to the Notes to violate this Article 10, but failure to give such
notice shall not affect the subordination of the Notes to the Senior
Indebtedness as provided in this Article 10.

SECTION 10.08.    SUBROGATION.

         After all Senior Indebtedness is paid in full in cash or cash
equivalents and until the Notes are paid in full, Holders of Notes shall be
subrogated (equally and ratably with all other Indebtedness pari passu with the
Notes) to the rights of holders of Senior Indebtedness to receive distributions
applicable to Senior Indebtedness to the extent that distributions otherwise
payable to the Holders of Notes have been applied to the payment of Senior
Indebtedness. A distribution made under this Article 10 to holders of Senior
Indebtedness that otherwise would have been made to Holders of Notes is not, as
between the Issuers and Holders, a payment by the Issuers on the Notes.

SECTION 10.09.    RELATIVE RIGHTS.

         This Article 10 defines the relative rights of Holders of Notes and
holders of Senior Indebtedness. Nothing in this Indenture shall:

         (1) impair, as between the Issuers and Holders of Notes, the obligation
of the Issuers, which is absolute and unconditional, to pay principal of and
interest and Liquidated Damages, if any, on the Notes in accordance with their
terms;

         (2) affect the relative rights of Holders of Notes and creditors of the
Issuers other than their rights in relation to holders of Senior Indebtedness;
or

         (3) prevent the Trustee or any Holder of Notes from exercising its
available remedies upon a Default or Event of Default, subject to the rights of
holders and owners of Senior Indebtedness to receive distributions and payments
otherwise payable to Holders of Notes.

         If the Issuers fail because of this Article 10 to pay principal of or
interest or Liquidated Damages, if any, on a Note on the due date, the failure
is still a Default or Event of Default.

SECTION 10.10.    SUBORDINATION MAY NOT BE IMPAIRED BY ISSUERS.

         No right of any holder of Senior Indebtedness to enforce the
subordination of the Indebtedness evidenced by the Notes shall be impaired by
any act or failure to act by the Issuers or any Holder or by the failure of the
Issuers or any Holder to comply with this Indenture.

SECTION 10.11.    DISTRIBUTION OR NOTICE TO REPRESENTATIVE.

         Whenever a distribution is to be made or a notice given to holders of
Senior Indebtedness, the distribution may be made and the notice given to their
Representative.

         Upon any payment or distribution of assets of the Issuers referred to
in this Article 10, the Trustee and the Holders of Notes shall be entitled to
rely upon any order or decree made by any court of competent jurisdiction or
upon any certificate of such Representative or of the liquidating trustee or
agent or other Person making any distribution to the Trustee or to the Holders
of Notes for the purpose of ascertaining the Persons entitled to participate in
such distribution, the holders of the Senior Indebtedness and other Indebtedness
of the Issuers, the amount thereof or payable thereon, the amount or amounts
paid or distributed thereon and all other facts pertinent thereto or to this
Article 10.

SECTION 10.12.    RIGHTS OF TRUSTEE AND PAYING AGENT.

         Notwithstanding the provisions of this Article 10 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Notes, unless the Trustee shall have received at its
Corporate Trust Office at least five Business Days prior to the date of such
payment written notice of facts that would cause the payment of any Obligations
with respect to the Notes to violate this Article 10. Only the Issuers or a
Representative may give the notice. Nothing in this Article 10 shall impair the
claims of, or payments to, the Trustee under or pursuant to Section 7.07 hereof.













                                       71
<PAGE>   80


         The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have if it were not Trustee. Any
Agent may do the same with like rights.

SECTION 10.13.    AUTHORIZATION TO EFFECT SUBORDINATION.

         Each Holder of Notes, by the Holder's acceptance thereof, authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article 10, and appoints the Trustee to act as such Holder's attorney-in-fact
for any and all such purposes. If the Trustee does not file a proper proof of
claim or proof of debt in the form required in any proceeding referred to in
Section 6.09 hereof at least 30 days before the expiration of the time to file
such claim, the Representative is hereby authorized to file an appropriate claim
for and on behalf of the Holders of the Notes.

SECTION 10.14.    NO WAIVER OF SUBORDINATION PROVISIONS.

          (a) No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act by any such
holder.

          (b) Without in any way limiting the generality of paragraph (a) of
this Section 10.14, the holders of Senior Indebtedness may, at any time and from
time to time, without the consent of or notice to the Trustee or any Holder,
without incurring responsibility to any Holder and without impairing or
releasing the subordination provided in this Article 10 or the obligations
hereunder of the Holders to the holders of Senior Indebtedness, do any one or
more of the following: (i) change the manner, place or terms of payment or
extend the time of payment of, or renew or alter, any Senior Indebtedness or any
instrument evidencing the same or any agreement under which Senior Indebtedness
is outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any
Person liable in any manner for the collection of Senior Indebtedness; and (iv)
exercise or refrain from exercising any rights against either Issuer or any
other Person.

SECTION 10.15.    AMENDMENTS.

         The provisions of this Article 10 shall not be amended or modified
without the written consent of the holders of all Senior Indebtedness.

                                   ARTICLE 11.
                                 NOTE GUARANTEES

SECTION 11.01.    GUARANTEE.

         Subject to this Article 11, each of the Guarantors hereby, jointly and
severally, unconditionally guarantees to each Holder of a Note authenticated and
delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the Notes or
the obligations of the Issuers hereunder or thereunder, that: (a) the principal
of and interest and Liquidated Damages, if any, on the Notes will be promptly
paid in full when due, whether at maturity, by acceleration, redemption or
otherwise, and interest on the overdue principal of and interest and Liquidated
Damages, if any, on the Notes, if any, if lawful, and all other obligations of
the Issuers to the Holders or the Trustee hereunder or thereunder will be
promptly paid in full or performed, all in accordance with the terms hereof and
thereof; and (b) in case of any extension of time of payment or 






                                       72
<PAGE>   81


renewal of any Notes or any of such other obligations, that same will be
promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, whether at stated maturity, by acceleration or otherwise.
Failing payment when due of any amount so guaranteed or any performance so
guaranteed for whatever reason, the Guarantors shall be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection.

         The Guarantors hereby agree that their obligations hereunder shall be
unconditional, irrespective of the validity, regularity or enforceability of the
Notes or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder of the Notes with respect to any provisions
hereof or thereof, the recovery of any judgment against the Issuers, any action
to enforce the same or any other circumstance which might otherwise constitute a
legal or equitable discharge or defense of a guarantor. Each Guarantor hereby
waives diligence, presentment, demand of payment, filing of claims with a court
in the event of insolvency or bankruptcy of the Issuers, any right to require a
proceeding first against the Issuers, protest, notice and all demands whatsoever
and covenant that this Note Guarantee shall not be discharged except by complete
performance of the obligations contained in the Notes and this Indenture.

         If any Holder or the Trustee is required by any court or otherwise to
return to the Issuers, the Guarantors or any custodian, trustee, liquidator or
other similar official acting in relation to either the Issuers or the
Guarantors, any amount paid by either to the Trustee or such Holder, this Note
Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect.

         Each Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby. Each
Guarantor further agrees that, as between the Guarantors, on the one hand, and
the Holders and the Trustee, on the other hand, (x) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article 6 hereof
for the purposes of this Note Guarantee, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any declaration of 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 the Guarantors
for the purpose of this Note Guarantee. The Guarantors shall have the right to
seek contribution from any non-paying Guarantor so long as the exercise of such
right does not impair the rights of the Holders under the Guarantee.

SECTION 11.02.    SUBORDINATION OF NOTE GUARANTEE.

         The Guarantors agree, and each Holder by accepting a Note agrees, that
the Obligations of each Guarantor under its Note Guarantee pursuant to this
Article 11 shall be junior and subordinated to the Senior Indebtedness of such
Guarantor on the same basis as the Notes are junior and subordinated to Senior
Indebtedness of the Company as provided in Article 10 hereof. For the purposes
of the foregoing sentence, the Trustee and the Holders shall have the right to
receive and/or retain payments by any of the Guarantors only at such times as
they may receive and/or retain payments in respect of the Notes pursuant to this
Indenture, including Section 4.15 hereof.

SECTION 11.03.    LIMITATION ON GUARANTOR LIABILITY.

         Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Note Guarantee of
such Guarantor not constitute a fraudulent transfer or conveyance for purposes
of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform 











                                       73
<PAGE>   82


Fraudulent Transfer Act or any similar federal or state law to the extent
applicable to any Note Guarantee. To effectuate the foregoing intention, the
Trustee, the Holders and the Guarantors hereby irrevocably agree that the
obligations of such Guarantor under its Note Guarantee and this Article 11 shall
be limited to the maximum amount as will, after giving effect to such maximum
amount and all other contingent and fixed liabilities of such Guarantor that are
relevant under such laws, and after giving effect to any collections from,
rights to receive contribution from or payments made by or on behalf of any
other Guarantor in respect of the obligations of such other Guarantor under this
Article 11, result in the obligations of such Guarantor under its Note Guarantee
not constituting a fraudulent transfer or conveyance.

SECTION 11.04.    EXECUTION AND DELIVERY OF NOTE GUARANTEE.

         To evidence its Note Guarantee set forth in Section 11.01, each
Guarantor hereby agrees that this Indenture shall be executed on behalf of such
Guarantor by its President or one of its Vice Presidents.

         If an Officer whose signature is on this Indenture no longer holds that
office at the time the Trustee authenticates the Note, the Note Guarantee shall
be valid nevertheless.

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

         In the event that the Company creates or acquires any new Subsidiaries
subsequent to the date of this Indenture, if required by Section 4.20 hereof,
the Company shall cause such Subsidiaries to execute supplemental indentures to
this Indenture in accordance with Section 4.20 hereof and this Article 11, to
the extent applicable.

SECTION 11.05.    GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.

         No Guarantor may consolidate with or merge with or into (whether or not
such Guarantor is the surviving Person) another Person whether or not affiliated
with such Guarantor unless:

          (a) subject to Section 11.05 hereof, the Person formed by or surviving
any such consolidation or merger (if other than a Guarantor or the Company)
unconditionally assumes all the obligations of such Guarantor, pursuant to a
supplemental indenture in form and substance reasonably satisfactory to the
Trustee, under the Notes, the Indenture and the Note Guarantee on the terms set
forth herein or therein;

          (b) immediately after giving effect to such transaction, no Default or
Event of Default exists; and

          (c) the Company would be permitted, immediately after giving effect to
such transaction, to incur at least $1.00 of additional Indebtedness pursuant to
the Fixed Charge Coverage Ratio test set forth in the first paragraph of Section
4.09 hereof.

         In case of any such consolidation, merger, sale or conveyance and upon
the assumption by the successor Person, by supplemental indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the Note
Guarantee endorsed upon the Notes and the due and punctual performance of all of
the covenants and conditions of this Indenture to be performed by the Guarantor,
such successor Person shall succeed to and be substituted for the Guarantor with
the same effect as if it had been named herein as a Guarantor. All the Note
Guarantees so issued shall in all respects have the 













                                       74
<PAGE>   83


same legal rank and benefit under this Indenture as the Note Guarantees
theretofore and thereafter issued in accordance with the terms of this Indenture
as though all of such Note Guarantees had been issued at the date of the
execution hereof.

         Except as set forth in Articles 4 and 5 hereof, and notwithstanding
clauses (a) and (b) above, nothing contained in this Indenture or in any of the
Notes shall prevent any consolidation or merger of a Guarantor with or into the
Company or another Guarantor, or shall prevent any sale or conveyance of the
property of a Guarantor as an entirety or substantially as an entirety to the
Company or another Guarantor.

SECTION 11.06.    RELEASES FOLLOWING SALE OF ASSETS.

         In the event of a sale or other disposition of all of the assets of any
Guarantor, by way of merger, consolidation or otherwise, or a sale or other
disposition of all of the capital stock of any Guarantor, then such Guarantor
(in the event of a sale or other disposition, by way of merger, consolidation or
otherwise, of all of the capital stock of such Guarantor) or the corporation
acquiring the property (in the event of a sale or other disposition of all or
substantially all of the assets of such Guarantor) will be released and relieved
of any obligations under its Note Guarantee; provided that the Net Proceeds of
such sale or other disposition are applied in accordance with the applicable
provisions of this Indenture, including without limitation Section 4.10 hereof.
Upon delivery by the Issuers to the Trustee of an Officers' Certificate and an
Opinion of Counsel to the effect that such sale or other disposition was made by
the Company in accordance with the applicable provisions of this Indenture,
including without limitation Section 4.10 hereof, the Trustee shall execute any
documents reasonably required in order to evidence the release of any Guarantor
from its obligations under its Note Guarantee.

         Any Guarantor not released from its obligations under its Note
Guarantee shall remain liable for the full amount of principal of and interest
and Liquidated Damages, if any, on the Notes and for the other obligations of
any Guarantor under this Indenture as provided in this Article 11.

PERSON TO WHOM THIS NOTE OR AN INTEREST HEREIN IS

TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. AS USED HEREIN,
THE TERMS "OFFSHORE TRANSACTION" AND "UNITED STATES" HAVE THE MEANINGS GIVEN TO
THEM BY RULE 902 OF REGULATION S UNDER THE SECURITIES ACT. THE INDENTURE
CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF
THIS NOTE IN VIOLATION OF THE FOREGOING.

         Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

         1.       INTEREST. Thermadyne Mfg. LLC, a Delaware limited liability
company ("Thermadyne"), and Thermadyne Capital Corp., a Delaware corporation
("Thermadyne Capital", together with Thermadyne, the "Issuers"), jointly and
severally, promise to pay interest on the principal amount of this Note at
9-7/8% per annum from May 22, 1998 until maturity and shall pay the Liquidated
Damages payable pursuant to Section 5 of the Registration Rights Agreement
referred to below. The Issuers will pay interest and Liquidated Damages
semi-annually on June 1 and December 1 of each year, or if any such day is not a
Business Day, on the next succeeding Business Day (each, an "Interest Payment
Date"). 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 May 22, 1998;
provided that if there is no existing Default in the payment of interest, and if
this Note is authenticated between a record date referred to on the face hereof
and the next succeeding Interest Payment Date, interest shall accrue from such
next succeeding Interest Payment Date; and provided further that the first
Interest Payment Date shall be December 1, 1998. The Issuers shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue principal and premium, if any, from time to time on demand at a rate
that is 1% per annum in excess of the rate then in effect; they shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest and Liquidated Damages
(without regard to any applicable grace periods) from time to time on demand at
the same rate to the extent lawful. Interest will be computed on the basis of a
360-day year of twelve 30-day months.

         2.       METHOD OF PAYMENT. The Issuers will pay interest on the Notes
(except defaulted interest) and Liquidated Damages to the Persons who are
registered Holders of Notes at the close of business on the May 15 or November
15 next preceding the Interest Payment Date, even if such Notes are cancelled
after such record date and on or before such Interest Payment Date, except as
provided in Section 2.12 of the Indenture with respect to defaulted interest.
The Notes will be payable as to principal, premium and Liquidated Damages, if
any, and interest at the office of the Paying Agent and Registrar. Holders of
Notes must surrender their Notes to the Paying Agent to collect principal
payments, and the Issuers may pay principal and interest and Liquidated Damages,
if any, by check and may mail checks to a Holder's registered address; provided
that all payments with respect to Global Notes and Definitive Notes, the Holders
of which have given wire transfer instructions to the Issuers, will be required
to be made by wire transfer of immediately available funds to the accounts
specified by the Holders thereof. Such payment shall be in such coin or currency
of the United States of America as at the time of payment is legal tender for
payment of public and private debts.

         3.       PAYING AGENT AND REGISTRAR. Initially, State Street Bank and
Trust Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Issuers may change any Paying Agent or Registrar without notice
to any Holder. The Issuers or any of their Subsidiaries may act in any such
capacity.

         4.       INDENTURE The Issuers issued the Notes under an Indenture
dated as of May 22, 1998 ("Indenture"), among the Issuers, the Guarantors and
the Trustee. The terms of the Notes include those




                                     A-1-4

<PAGE>   5

stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939, as amended (15 U.S. Code ss.ss. 77aaa-77bbbb). The
Notes are subject to all such terms, and Holders are referred to the Indenture
and such Act for a statement of such terms. To the extent any provision of this
Note conflicts with the express provisions of the Indenture, the provisions of
the Indenture shall govern and be controlling. The Notes are obligations of the
Issuers initially limited to $207 million in aggregate principal amount.

         5.       OPTIONAL REDEMPTION.

         (a)      Except as provided in subparagraph (b) of this Paragraph 5,
the Notes will not be redeemable at the Issuers' option prior to June 1, 2003.
Thereafter, the Notes will be subject to redemption at any time at the option of
the Issuers, in whole or in part, upon not less than 30 nor more than 60 days'
notice, in cash at the redemption prices (expressed as percentages of principal
amount) set forth below, plus accrued and unpaid interest and Liquidated
Damages, if any, thereon to the applicable redemption date, if redeemed during
the twelve-month period beginning on June 1 of the years indicated below:

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

         (b)      Notwithstanding the provisions of subparagraph (a) of this
Paragraph 5, on or prior to June 1, 2001, the Issuers may redeem up to 35% of
the aggregate principal amount of Notes ever issued under the Indenture in cash
at a redemption price of 109.875% of the principal amount thereof, plus accrued
and unpaid interest and Liquidated Damages, if any, thereon to the redemption
date, with the net cash proceeds of one or more Public Equity Offerings;
provided that at least 65% of the aggregate principal amount of Notes ever
issued under the Indenture remains outstanding immediately after the occurrence
of any such redemption; and provided further that such redemption shall occur
within 90 days of the date of the closing of any such Public Equity Offering.

         (c)      In addition, at any time prior to June 1, 2003, the Issuers
may, at their option upon the occurrence of a Change of Control, redeem the
Notes, in whole but not in part, upon not less than 30 nor more than 60 days'
prior notice (but in no event may any such redemption occur more than 60 days
after the occurrence of such Change of Control), in cash at a redemption price
equal to (i) the present value of the sum of all the remaining interest
(excluding accrued and unpaid interest, if any), premium and principal payments
that would become due on the Notes as if the Notes were to remain outstanding
and be redeemed on June 1, 2003, computed using a discount rate equal to the
Treasury Rate plus 50 basis points, plus (ii) accrued and unpaid interest and
Liquidated Damages, if any, to the date of redemption.

         6.       MANDATORY REDEMPTION.

         Except as set forth in paragraph 7 below, the Issuers are not required
to make mandatory redemption of, or sinking fund payments with respect to, the
Notes.

         7.       REPURCHASE AT OPTION OF HOLDER.

         (a)      Upon the occurrence of a Change of Control (such date being
the "Change of Control Payment"), each Holder of Notes shall have the right to
require the Issuers to purchase all or any part (equal to $1,000 or an integral
multiple thereof) of such Holder's Notes pursuant to an offer at an offer price
in cash equal to 101% of the aggregate principal amount thereof, plus accrued
and unpaid interest and Liquidated Damages, if any, thereon to the date of
repurchase. Within 60 days following any Change of Control, subject to the
provisions of the Indenture, the Issuers shall mail a notice to each Holder of
Notes at such Holder's registered address setting forth the procedures governing
the offer as required by the Indenture.

         (b)      When the aggregate amount of Excess Proceeds exceeds $15.0
million, the Issuers will be required to make an offer to all Holders of Notes
to purchase the maximum principal amount of Notes that may be purchased out of
Excess Proceeds, at an offer price in cash in an amount equal to 100% of the
principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages, if any, thereon to the date of purchase, in accordance with the
procedures set forth in the Indenture. Holders of Notes that are subject to an
offer to purchase will receive an Asset Sale Offer from the Issuers prior to any
related purchase date and may elect to have such Notes purchased by completing
the form entitled "Option of Holder to Elect Purchase" on the reverse side of
this Note.

         8.       NOTICE OF REDEMPTION. Notice of any redemption or offer to
purchase will be mailed at least 30 days but not more than 60 days before the
redemption or purchase date to each Holder of Notes to be redeemed or purchased
at such Holder's registered address. Notes in denominations larger than $1,000
may be redeemed in part but only in whole multiples of $1,000, unless all of the
Notes held by a Holder are to be redeemed. On and after the redemption date,
interest and Liquidated Damages, if any, will cease to accrue on Notes or
portions thereof called for redemption.

         9.       DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Notes may be registered and Notes may be exchanged as
provided in the Indenture. The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
and the Issuers may require a Holder to pay any taxes and fees required by law
or permitted by the Indenture. The Issuers need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, the Issuers
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

         10.      PERSONS DEEMED OWNERS. The registered Holder of a Note may be
treated as its owner for all purposes.

         11.      AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
exceptions set forth in the Indenture, the Indenture, the Note Guarantees or the
Notes may be amended or supplemented with the consent of the Holders of at least
a majority in principal amount of the Notes then outstanding (including, without
limitation, consents obtained in connection with a purchase of, or tender offer
or exchange offer for, Notes), and any existing default or compliance with any
provision of the Indenture or the Notes may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes


                                     A-1-6

<PAGE>   7

(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, Notes). Notwithstanding the
foregoing, without the consent of any Holder of Notes, the Issuers, the
Guarantors and the Trustee may amend or supplement the Indenture, the Note
Guarantees or the Notes to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Notes in addition to or in place of certificated
Notes, to provide for the assumption of the Issuers' obligations to Holders of
Notes in the case of a merger or consolidation or sale of all or substantially
all of the Issuers' assets, to make any change that would provide any additional
rights or benefits to the Holders of Notes or that does not materially adversely
affect the legal rights under the Indenture of any such Holder, or to comply
with requirements of the Commission in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act or to provide for
additional Note Guarantees of the Notes.

         12.      DEFAULTS AND REMEDIES.

         (a) Events of Default include: (a) default for 30 days in the payment
when due of interest on, or Liquidated Damages with respect to, the Notes
(whether or not prohibited by the subordination provisions of the Indenture);
(b) default in payment when due of the principal of or premium, if any, on the
Notes (whether or not prohibited by the subordination provisions of the
Indenture); (c) failure by the Issuers or any of their Restricted Subsidiaries
for 30 days after receipt of notice from the Trustee or Holders of at least 25%
in principal amount of the Notes then outstanding to comply with the provisions
of Sections 4.07, 4.09, 4.10, 4.15 and 5.01 of the Indenture; (d) failure by the
Issuers for 60 days after notice from the Trustee or the Holders of at least 25%
in principal amount of the Notes then outstanding to comply with any of their
other agreements in the Indenture or the Notes; (e) default under any mortgage,
indenture or instrument under which there may be issued or by which there may be
secured or evidenced any Indebtedness for money borrowed by the Issuers or any
of their Restricted Subsidiaries (or the payment of which is guaranteed by the
Issuers or any of their Restricted Subsidiaries), whether such Indebtedness or
guarantee now exists, or is created after the date of the Indenture, which
default (i) is caused by a failure to pay Indebtedness at its stated final
maturity (after giving effect to any applicable grace period provided in such
Indebtedness) (a "Payment Default") or (ii) results in the acceleration of such
Indebtedness prior to its stated final maturity and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other
such Indebtedness under which there has been a Payment Default or the maturity
of which has been so accelerated, aggregates $10.0 million or more; (f) failure
by the Issuers or any of their Restricted Subsidiaries to pay final judgments
aggregating in excess of $10.0 million (net of any amounts with respect to which
a reputable and creditworthy insurance company has acknowledged liability in
writing), which judgments are not paid, discharged or stayed for a period of 60
days; (g) except as permitted by the Indenture, any Note Guarantee shall be held
in any judicial proceeding to be unenforceable or invalid or shall cease for any
reason to be in full force and effect or any Guarantor, or any Person acting on
behalf of any Guarantor, shall deny or disaffirm its obligations under its Note
Guarantee; and (h) certain events of bankruptcy or insolvency with respect to
the Issuers or any of their Restricted Subsidiaries that is a Significant
Subsidiary. If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately; provided that, so long
as any Indebtedness permitted to be incurred pursuant to the New Credit Facility
shall be outstanding, such acceleration shall not be effective until the earlier
of (a) an acceleration of any such Indebtedness under the New Credit Facility or
(b) five business days after receipt by the Issuers and the administrative agent
under the New Credit Facility of written notice of such acceleration.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency with respect to the Issuers or any of
their Restricted Subsidiaries that is a Significant Subsidiary, all outstanding
Notes will become due and payable without further action or notice.


                                     A-1-7
<PAGE>   8

         (b) In the event of a declaration of acceleration of the Notes because
an Event of Default has occurred and is continuing as a result of the
acceleration of any Indebtedness described in clause (e) of the preceding
paragraph, the declaration of acceleration of the Notes shall be automatically
annulled if the holders of any Indebtedness described in clause (e) have
rescinded the declaration of acceleration in respect of such Indebtedness within
30 days of the date of such declaration and if (i) the annulment of the
acceleration of the Notes would not conflict with any judgment or decree of a
court of competent jurisdiction and (ii) all existing Events of Default, except
non-payment of principal or interest on the Notes that became due solely because
of the acceleration of the Notes, have been cured or waived.

         13.      SUBORDINATION. The payment of Subordinated Note Obligations
will be subordinated in right of payment, as set forth in the Indenture, to the
prior payment in full in cash or cash equivalents of all Senior Indebtedness,
whether outstanding on the date of the Indenture or thereafter incurred. The
Issuers agree, and each Holder by accepting a Note agrees, that the payment of
principal of, premium and interest and Liquidated Damages, if any, on the Notes
is subordinated in right of payment, to the extent and in the manner provided in
the Indenture, to the prior payment in full in cash or cash equivalents of all
Senior Indebtedness (whether outstanding on the date hereof or thereafter
created, incurred, assumed or guaranteed), and that the subordination is for the
benefit of the holders of Senior Indebtedness.

         14.      NOTE GUARANTEES. The payment of principal of, premium, and
interest and Liquidated Damages, if any, on the Notes are unconditionally
guaranteed, jointly and severally, on a senior subordinated basis by the
Guarantors.

         15.      ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES. In
addition to the rights provided to Holders of Notes under the Indenture, Holders
of Restricted Global Notes shall have the rights set forth in the Registration
Rights Agreement dated as of May 22, 1998, among the Issuers, the Guarantors and
the parties named on the signature pages thereof (the "Registration Rights
Agreement").

         16.      TRUSTEE DEALINGS WITH ISSUERS. The Trustee, in its individual
or any other capacity, may make loans to, accept deposits from, and perform
services for the Issuers or their Affiliates, and may otherwise deal with any
Issuer or its Affiliates, as if it were not the Trustee.

         17.      NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder, of any Issuer, as such, shall not have any
liability for any obligations of the Issuers under the Notes or the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of the Notes.

         18.      AUTHENTICATION. This Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

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

         20.      CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Issuers have caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders.

UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND (3) AGREES THAT IT WILL
DELIVER TO EACH PERSON TO WHOM THIS NOTE OR AN INTEREST HEREIN IS TRANSFERRED A
NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. AS USED HEREIN, THE TERMS
"OFFSHORE TRANSACTION" AND "UNITED STATES" HAVE THE MEANINGS GIVEN TO THEM BY
RULE 902 OF REGULATION S UNDER THE SECURITIES ACT. THE INDENTURE CONTAINS A
PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE
IN VIOLATION OF THE FOREGOING.

         Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

         1.       INTEREST. Thermadyne Mfg. LLC, a Delaware limited liability
company ("Thermadyne"), and Thermadyne Capital Corp., a Delaware corporation
("Thermadyne Capital", together with Thermadyne, the "Issuers"), jointly and
severally, promise to pay interest on the principal amount of this Note at
9-7/8% per annum from May 22, 1998 until maturity and shall pay the Liquidated
Damages payable pursuant to Section 5 of the Registration Rights Agreement
referred to below. The Issuers will pay interest and Liquidated Damages
semi-annually on June 1 and December 1 of each year, or if any such day is not a
Business Day, on the next succeeding Business Day (each, an "Interest Payment
Date"). 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 May 22, 1998;
provided that if there is no existing Default in the payment of interest, and if
this Note is authenticated between a record date referred to on the face hereof
and the next succeeding Interest Payment Date, interest shall accrue from such
next succeeding Interest Payment Date; and provided further that the first
Interest Payment Date shall be December 1, 1998. The Issuers shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue principal and premium, if any, from time to time on demand at a rate
that is 1% per annum in excess of the rate then in effect; they shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest and Liquidated Damages
(without regard to any applicable grace periods) from time to time on demand at
the same rate to the extent lawful. Interest will be computed on the basis of a
360-day year of twelve 30-day months.

         2.       METHOD OF PAYMENT. The Issuers will pay interest on the Notes
(except defaulted interest) and Liquidated Damages to the Persons who are
registered Holders of Notes at the close of business on the May 15 or November
15 next preceding the Interest Payment Date, even if such Notes are cancelled
after such record date and on or before such Interest Payment Date, except as
provided in Section 2.12 of the Indenture with respect to defaulted interest.
The Notes will be payable as to principal, premium and Liquidated Damages, if
any, and interest at the office of the Paying Agent and Registrar. Holders of
Notes must surrender their Notes to the Paying Agent to collect principal
payments, and the Issuers may pay principal and interest and Liquidated Damages,
if any, by check and may mail checks to a Holder's registered address; provided
that all payments with respect to Global Notes and Definitive Notes, the Holders
of which have given wire transfer instructions to the Issuers, will be required
to be made by wire transfer of immediately available funds to the accounts
specified by the Holders thereof. Such payment shall be in such coin or currency
of the United States of America as at the time of payment is legal tender for
payment of public and private debts.

         3.       PAYING AGENT AND REGISTRAR. Initially, State Street Bank and
Trust Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Issuers may change any Paying Agent or Registrar without notice
to any Holder. The Issuers or any of their Subsidiaries may act in any such
capacity.

         4.       INDENTURE The Issuers issued the Notes under an Indenture
dated as of May 22, 1998 ("Indenture"), among the Issuers, the Guarantors and
the Trustee. The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended (15 U.S. Code ss.ss. 77aaa-77bbbb). The Notes are subject to
all such terms, and Holders are referred to the Indenture and such Act for a
statement of such terms. To the extent any provision of this Note conflicts with
the express provisions of the Indenture, the provisions of the Indenture shall
govern and be controlling. The Notes are obligations of the Issuers initially
limited to $207 million in aggregate principal amount.

         5.       OPTIONAL REDEMPTION.

         (a)      Except as provided in subparagraph (b) of this Paragraph 5,
the Notes will not be redeemable at the Issuers' option prior to June 1, 2003.
Thereafter, the Notes will be subject to redemption at any time at the option of
the Issuers, in whole or in part, upon not less than 30 nor more than 60 days'
notice, in cash at the redemption prices (expressed as percentages of principal
amount) set forth below, plus accrued and unpaid interest and Liquidated
Damages, if any, thereon to the applicable redemption date, if redeemed during
the twelve-month period beginning on June 1 of the years indicated below:

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

         (b)      Notwithstanding the provisions of subparagraph (a) of this
Paragraph 5, on or prior to June 1, 2001, the Issuers may redeem up to 35% of
the aggregate principal amount of Notes ever issued under the Indenture in cash
at a redemption price of 109.875% of the principal amount thereof, plus accrued
and unpaid interest and Liquidated Damages, if any, thereon to the redemption
date, with the net cash proceeds of one or more Public Equity Offerings;
provided that at least 65% of the aggregate principal amount of Notes ever
issued under the Indenture remains outstanding immediately after the occurrence
of any such redemption; and provided further that such redemption shall occur
within 90 days of the date of the closing of any such Public Equity Offering.

         (c)      In addition, at any time prior to June 1, 2003, the Issuers
may, at their option upon the occurrence of a Change of Control, redeem the
Notes, in whole but not in part, upon not less than 30 nor more than 60 days'
prior notice (but in no event may any such redemption occur more than 60 days
after the occurrence of such Change of Control), in cash at a redemption price
equal to (i) the present value of the sum of all the remaining interest
(excluding accrued and unpaid interest, if any), premium and principal payments
that would become due on the Notes as if the Notes were to remain outstanding
and be redeemed on June 1, 2003, computed using a discount rate equal to the
Treasury Rate plus 50 basis points, plus (ii) accrued and unpaid interest and
Liquidated Damages, if any, to the date of redemption.

         6.       MANDATORY REDEMPTION.

         Except as set forth in paragraph 7 below, the Issuers are not required
to make mandatory redemption of, or sinking fund payments with respect to, the
Notes.





         7.       REPURCHASE AT OPTION OF HOLDER.

         (a)      Upon the occurrence of a Change of Control (such date being
the "Change of Control Payment"), each Holder of Notes shall have the right to
require the Issuers to purchase all or any part (equal to $1,000 or an integral
multiple thereof) of such Holder's Notes pursuant to an offer at an offer price
in cash equal to 101% of the aggregate principal amount thereof, plus accrued
and unpaid interest and Liquidated Damages, if any, thereon to the date of
repurchase. Within 60 days following any Change of Control, subject to the
provisions of the Indenture, the Issuers shall mail a notice to each Holder of
Notes at such Holder's registered address setting forth the procedures governing
the offer as required by the Indenture.

         (b)      When the aggregate amount of Excess Proceeds exceeds $15.0
million, the Issuers will be required to make an offer to all Holders of Notes
to purchase the maximum principal amount of Notes that may be purchased out of
Excess Proceeds, at an offer price in cash in an amount equal to 100% of the
principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages, if any, thereon to the date of purchase, in accordance with the
procedures set forth in the Indenture. Holders of Notes that are subject to an
offer to purchase will receive an Asset Sale Offer from the Issuers prior to any
related purchase date and may elect to have such Notes purchased by completing
the form entitled "Option of Holder to Elect Purchase" on the reverse side of
this Note.

         8.       NOTICE OF REDEMPTION. Notice of any redemption or offer to
purchase will be mailed at least 30 days but not more than 60 days before the
redemption or purchase date to each Holder of Notes to be redeemed or purchased
at such Holder's registered address. Notes in denominations larger than $1,000
may be redeemed in part but only in whole multiples of $1,000, unless all of the
Notes held by a Holder are to be redeemed. On and after the redemption date,
interest and Liquidated Damages, if any, will cease to accrue on Notes or
portions thereof called for redemption.

         9.       DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Notes may be registered and Notes may be exchanged as
provided in the Indenture. The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
and the Issuers may require a Holder to pay any taxes and fees required by law
or permitted by the Indenture. The Issuers need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, the Issuers
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

         10.      PERSONS DEEMED OWNERS. The registered Holder of a Note may be
treated as its owner for all purposes.

         11.      AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
exceptions set forth in the Indenture, the Indenture, the Note Guarantees or the
Notes may be amended or supplemented with the consent of the Holders of at least
a majority in principal amount of the Notes then outstanding (including, without
limitation, consents obtained in connection with a purchase of, or tender offer
or exchange offer for, Notes), and any existing default or compliance with any
provision of the Indenture or the Notes may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes
(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, Notes). Notwithstanding the
foregoing, without the consent of any Holder of Notes, the Issuers, the
Guarantors and the Trustee may amend or supplement the Indenture, the Note
Guarantees or the Notes to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Notes in addition to or in place of certificated
Notes, to provide for the assumption of the Issuers' obligations to Holders of
Notes in the case of a merger or consolidation or sale of all or substantially
all of the Issuers' assets, to make any change that would provide any additional
rights or benefits to the Holders of Notes or that does not materially adversely
affect the legal rights under the Indenture of any such Holder, or to comply
with requirements of the Commission in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act or to provide for
additional Note Guarantees of the Notes.

         12.      DEFAULTS AND REMEDIES.

         (a) Events of Default include: (a) default for 30 days in the payment
when due of interest on, or Liquidated Damages with respect to, the Notes
(whether or not prohibited by the subordination provisions of the Indenture);
(b) default in payment when due of the principal of or premium, if any, on the
Notes (whether or not prohibited by the subordination provisions of the
Indenture); (c) failure by the Issuers or any of their Restricted Subsidiaries
for 30 days after receipt of notice from the Trustee or Holders of at least 25%
in principal amount of the Notes then outstanding to comply with the provisions
of Sections 4.07, 4.09, 4.10, 4.15 and 5.01 of the Indenture; (d) failure by the
Issuers for 60 days after notice from the Trustee or the Holders of at least 25%
in principal amount of the Notes then outstanding to comply with any of their
other agreements in the Indenture or the Notes; (e) default under any mortgage,
indenture or instrument under which there may be issued or by which there may be
secured or evidenced any Indebtedness for money borrowed by the Issuers or any
of their Restricted Subsidiaries (or the payment of which is guaranteed by the
Issuers or any of their Restricted Subsidiaries), whether such Indebtedness or
guarantee now exists, or is created after the date of the Indenture, which
default (i) is caused by a failure to pay Indebtedness at its stated final
maturity (after giving effect to any applicable grace period provided in such
Indebtedness) (a "Payment Default") or (ii) results in the acceleration of such
Indebtedness prior to its stated final maturity and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other
such Indebtedness under which there has been a Payment Default or the maturity
of which has been so accelerated, aggregates $10.0 million or more; (f) failure
by the Issuers or any of their Restricted Subsidiaries to pay final judgments
aggregating in excess of $10.0 million (net of any amounts with respect to which
a reputable and creditworthy insurance company has acknowledged liability in
writing), which judgments are not paid, discharged or stayed for a period of 60
days; (g) except as permitted by the Indenture, any Note Guarantee shall be held
in any judicial proceeding to be unenforceable or invalid or shall cease for any
reason to be in full force and effect or any Guarantor, or any Person acting on
behalf of any Guarantor, shall deny or disaffirm its obligations under its Note
Guarantee; and (h) certain events of bankruptcy or insolvency with respect to
the Issuers or any of their Restricted Subsidiaries that is a Significant
Subsidiary. If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately; provided that, so long
as any Indebtedness permitted to be incurred pursuant to the New Credit Facility
shall be outstanding, such acceleration shall not be effective until the earlier
of (a) an acceleration of any such Indebtedness under the New Credit Facility or
(b) five business 




                                     A-2-7
<PAGE>   20

days after receipt by the Issuers and the administrative agent under the New
Credit Facility of written notice of such acceleration. Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency with respect to the Issuers or any of their Restricted
Subsidiaries that is a Significant Subsidiary, all outstanding Notes will become
due and payable without further action or notice.

         (b) In the event of a declaration of acceleration of the Notes because
an Event of Default has occurred and is continuing as a result of the
acceleration of any Indebtedness described in clause (e) of the preceding
paragraph, the declaration of acceleration of the Notes shall be automatically
annulled if the holders of any Indebtedness described in clause (e) have
rescinded the declaration of acceleration in respect of such Indebtedness within
30 days of the date of such declaration and if (i) the annulment of the
acceleration of the Notes would not conflict with any judgment or decree of a
court of competent jurisdiction and (ii) all existing Events of Default, except
non-payment of principal or interest on the Notes that became due solely because
of the acceleration of the Notes, have been cured or waived.

         13.      SUBORDINATION. The payment of Subordinated Note Obligations
will be subordinated in right of payment, as set forth in the Indenture, to the
prior payment in full in cash or cash equivalents of all Senior Indebtedness,
whether outstanding on the date of the Indenture or thereafter incurred. The
Issuers agree, and each Holder by accepting a Note agrees, that the payment of
principal of, premium and interest and Liquidated Damages, if any, on the Notes
is subordinated in right of payment, to the extent and in the manner provided in
the Indenture, to the prior payment in full in cash or cash equivalents of all
Senior Indebtedness (whether outstanding on the date hereof or thereafter
created, incurred, assumed or guaranteed), and that the subordination is for the
benefit of the holders of Senior Indebtedness.

         14.      NOTE GUARANTEES. The payment of principal of, premium, and
interest and Liquidated Damages, if any, on the Notes are unconditionally
guaranteed, jointly and severally, on a senior subordinated basis by the
Guarantors.

         15.      ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES. In
addition to the rights provided to Holders of Notes under the Indenture, Holders
of Restricted Global Notes shall have the rights set forth in the Registration
Rights Agreement dated as of May 22, 1998, among the Issuers, the Guarantors and
the parties named on the signature pages thereof (the "Registration Rights
Agreement").

         16.      TRUSTEE DEALINGS WITH ISSUERS. The Trustee, in its individual
or any other capacity, may make loans to, accept deposits from, and perform
services for the Issuers or their Affiliates, and may otherwise deal with any
Issuer or its Affiliates, as if it were not the Trustee.

         17.      NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder, of any Issuer, as such, shall not have any
liability for any obligations of the Issuers under the Notes or the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of the Notes.

         18.      AUTHENTICATION. This Note shall not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

         19.      ABBREVIATIONS. Customary abbreviations may be used in the name
of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (=



                                     A-2-8

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

         20.      CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Issuers have caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

         The Issuers will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Registration Rights Agreement.
Requests may be made to:

as in effect on the date of the Indenture.

earliest to occur of (i) the date on which such Series A Note is exchanged in

(and the purchasers thereof have been issued Series B Notes), and (iii) the
date on which such Series A Note is distributed to the public pursuant to Rule
144 under the Act and (b) each Series B Note issued to a Broker-Dealer in the
Exchange Offer until the date on which such Series B Note is disposed of by
such Broker-Dealer pursuant to the "Plan of Distribution" contemplated by the
Exchange Offer Registration Statement (including the delivery of the Prospectus
contained therein).

SECTION 2. HOLDERS

       A Person is deemed to be a holder of Transfer Restricted Securities
(each, a "Holder") whenever such Person is the holder of record of Transfer
Restricted Securities.

SECTION 3. REGISTERED EXCHANGE OFFER

       (a)      Unless the Exchange Offer shall not be permitted by applicable
federal law (after the procedures set forth in Section 6(a)(i) hereof have been
complied with), the Issuers and the Guarantors shall use their reasonable best
efforts to (i) cause the Exchange Offer Registration Statement to be filed with
the Commission as soon as practicable after the Closing Date, but in no event
later than 90 days after the Closing Date (such 90th day, the "Filing
Deadline"), (ii) cause such Exchange Offer Registration Statement to become
effective at the earliest possible time, but in no event later than 180 days
after the Closing Date (such 180th day, the "Effectiveness Deadline"), (iii) in
connection with the foregoing, (A) file all pre-effective amendments to such
Exchange Offer Registration Statement as may be necessary in order to cause it
to become effective, and (B) subject to the proviso in Section 6(c)(xii)
hereof, cause all necessary filings, if any, in connection with the
registration and qualification of the Series B Notes to be made under the Blue
Sky laws of such jurisdictions as are necessary to permit Consummation of the
Exchange Offer, and (iv) upon the effectiveness of such Exchange Offer
Registration Statement, commence and, within the time periods contemplated by
Section 3(b) hereof, Consummate the Exchange Offer.  The Exchange Offer shall
be on the appropriate form permitting (i) registration of the Series B Notes to
be offered in exchange for the Series A Notes that are Transfer Restricted
Securities and (ii) resales of Series B Notes by Broker-Dealers that tendered
into the Exchange Offer Series A Notes that such Broker-Dealer acquired for its
own account as a result of market-making activities or other trading activities
(other than Series A Notes acquired directly from the Issuers or any of their
Affiliates) as contemplated by Section 3(c) hereof.

       (b)      The Issuers and the Guarantors shall use their reasonable best
efforts to cause the Exchange Offer Registration Statement to be effective
continuously, and shall keep the Exchange Offer open for a period of not less
than the minimum period required under applicable federal and state securities
laws to Consummate the Exchange Offer; provided that in no event shall such
period be less than 20 Business Days.  The Issuers shall cause the Exchange
Offer to comply with all applicable federal and state securities laws.  No
securities other than the Series B Notes shall be included in the Exchange
Offer Registration Statement.  The Issuers shall use their reasonable best
efforts to cause the Exchange Offer to be





                                       3





<PAGE>   5



Consummated on the earliest practicable date after the Exchange Offer
Registration Statement has become effective, but in no event later than 30
Business Days thereafter (such 30th day, the "Consummation Deadline").

       (c)      The Issuers shall include a "Plan of Distribution" section in
the Prospectus contained in the Exchange Offer Registration Statement and
indicate therein that any Broker-Dealer who holds Transfer Restricted
Securities that were acquired for the account of such Broker-Dealer as a result
of market-making activities or other trading activities (other than Series A
Notes acquired directly from the Issuers or any Affiliate of the Issuers), may
exchange such Transfer Restricted Securities pursuant to the Exchange Offer.
Such "Plan of Distribution" section shall also contain all other information
with respect to such sales by such Broker-Dealers that the Commission may
require in order to permit such sales pursuant thereto, but such "Plan of
Distribution" shall not name any such Broker-Dealer or disclose the amount of
Transfer Restricted Securities held by any such Broker-Dealer, except to the
extent required by the Commission.

       Because such Broker-Dealer may be deemed to be an "underwriter" within
the meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with its initial sale of any Series B
Notes received by such Broker-Dealer in the Exchange Offer, the Issuers shall
permit the use of the Prospectus contained in the Exchange Offer Registration
Statement by such Broker-Dealer to satisfy such prospectus delivery requirement
for a period of 90 days following the Consummation Date.  To the extent
necessary to ensure that the prospectus contained in the Exchange Offer
Registration Statement is available for sales of Series B Notes by
Broker-Dealers, the Issuers and the Guarantors agree to use their reasonable
best efforts to keep the Exchange Offer Registration Statement continuously
effective, supplemented, amended and current as required by and subject to the
provisions of Sections 6(a) and (c) hereof and in conformity with the
requirements of this Agreement, the Act and the policies, rules and regulations
of the Commission as announced from time to time, for a period of 90 days from
the Consummation Date or such shorter period as will terminate when no Transfer
Restricted Securities are outstanding.  The Issuers shall provide sufficient
copies of the latest version of such Prospectus to such Broker-Dealers,
promptly upon request, at any time during such period.

SECTION 4. SHELF REGISTRATION

       (a)      Shelf Registration.   If (i) the Exchange Offer is not permitted
by applicable law (after the Issuers and the Guarantors have complied with the
procedures set forth in Section 6(a)(i) hereof) or (ii) if any Holder of
Transfer Restricted Securities shall notify the Issuers in writing within 20
Business Days following the Consummation Deadline that (A) based on an opinion
of counsel, such Holder was prohibited by law or Commission policy from
participating in the Exchange Offer or (B) such Holder is a Broker-Dealer and
holds Series A Notes acquired directly from the Issuers, then the Issuers and
the Guarantors shall:

                (x) cause to be filed, on or prior to 90 days after the earlier
         of (i) the date on which the Issuers determine that the Exchange Offer
         Registration Statement cannot be filed as a result of Section 4(a)(i)
         hereof and (ii) the date on which the Issuers receive the notice
         specified in Section 4(a)(ii) hereof (such earlier date, the "Filing
         Deadline"), a shelf registration statement (the "Shelf Registration
         Statement") pursuant to Rule 415 under the Act (which may be an
         amendment to the Exchange Offer Registration Statement) relating to
         (1) all Transfer Restricted Securities in the case





                                       4





<PAGE>   6


       of clause (a)(i) above or (2) the Transfer Restricted Securities
       specified in any notice in the case of clause (a)(ii) above; and

                (y) shall use their reasonable best efforts to cause such Shelf
       Registration Statement to become effective on or prior to 180 days
       after the Filing Deadline for the Shelf Registration Statement (such
       180th day, the "Effectiveness Deadline").

       If, after the Issuers and the Guarantors have filed an Exchange Offer
Registration Statement that satisfies the requirements of Section 3(a) hereof,
the Issuers are required to file and make effective a Shelf Registration
Statement solely because the Exchange Offer is not permitted under applicable
federal law (i.e., Section 4(a)(i) hereof), then the filing of the Exchange
Offer Registration Statement shall be deemed to satisfy the requirements of
clause (x) above; provided that, in such event, the Issuers and the Guarantors
shall remain obligated to meet the Effectiveness Deadline set forth in clause
(y).

       To the extent necessary to ensure that the Shelf Registration Statement
is available for sales of Transfer Restricted Securities by the Holders thereof
entitled to the benefit of this Section 4(a) and the other securities required
to be registered therein pursuant to Section 6(b)(ii) hereof, the Issuers and
the Guarantors shall use their reasonable best efforts to keep any Shelf
Registration Statement required by this Section 4(a) continuously effective,
supplemented, amended and current as required by and subject to the provisions
of Sections 6(b) and (c) hereof and in conformity with the requirements of this
Agreement, the Act and the policies, rules and regulations of the Commission as
announced from time to time, until the later of (a) the date on which the
Initial Purchaser is no longer deemed to be an Affiliate of the Issuers, and
(b) the earlier of the second anniversary of the Closing Date (as such date may
be extended pursuant to Section 6(d) hereof) and such earlier date when no
Transfer Restricted Securities covered by such Shelf Registration Statement
remain outstanding.

       (b)     Provision by Holders of Certain Information in Connection with
the Shelf Registration Statement.  No Holder of Transfer Restricted Securities
may include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Issuers in writing, within 20 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein.  No Holder of Transfer
Restricted Securities shall be entitled to liquidated damages pursuant to
Section 5 hereof unless and until such Holder shall have provided all such
information.  Each selling Holder agrees to promptly furnish additional
information required to be disclosed in order to make the information
previously furnished to the Issuers by such Holder not materially misleading.

       (c)     Holders of Transfer Restricted Securities that do not give the
written notice within the 20 Business Day period set forth in Section 4(a)
hereof, if required to be given, will no longer have any registration rights
pursuant to this Section 4 and will not be entitled to any Liquidated Damages
pursuant to Section 5 hereof in respect of the Issuers' and the Guarantors'
obligations with respect to the Shelf Registration Statement.

SECTION 5. LIQUIDATED DAMAGES

       If (i) any Registration Statement required by this Agreement is not
filed with the Commission on or prior to the applicable Filing Deadline, (ii)
any such Registration Statement has not been declared effective by the
Commission on or prior to the applicable Effectiveness Deadline, (iii) the
Exchange Offer has not been Consummated on or prior to the Consummation
Deadline or (iv) any Registration Statement required by this Agreement is filed
and declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose without being succeeded within ten Business
Days by a post-effective amendment to such Registration Statement that cures
such failure and that is itself declared effective ten Business Days of filing
such post-effective amendment to such Registration Statement (each such event
referred to in clauses (i) through (iv), a "Registration Default"), then the
Issuers and the Guarantors hereby agree to pay to each Holder of Transfer
Restricted Securities affected thereby liquidated damages in an amount equal to
$.05 per week per $1,000 in principal amount of Transfer Restricted Securities
held by such Holder for each week or portion thereof that the Registration
Default continues for the first 90-day period immediately following the
occurrence of such Registration Default.  The amount of the liquidated damages
shall increase by an additional $.05 per week per $1,000 in principal amount of
Transfer Restricted Securities with respect to each subsequent 90-day period
until all Registration Defaults have been cured, up to a maximum amount of
liquidated damages of $.25 per week per $1,000 in principal amount of Transfer
Restricted Securities; provided that the Issuers and the Guarantors shall in no
event be required to pay liquidated damages for more than one Registration
Default at any given time.  Notwithstanding anything to the contrary set forth
herein, (1) upon filing of the Exchange Offer Registration Statement (and/or,
if applicable, the Shelf Registration Statement), in the case of (i) above, (2)
upon the effectiveness of the Exchange Offer Registration Statement (and/or, if
applicable, the Shelf Registration Statement), in the case of (ii) above, (3)
upon Consummation of the Exchange Offer, in the case of (iii) above, (4) upon
the filing of a post-effective amendment to the Registration Statement or an
additional Registration Statement that causes the Exchange Offer Registration
Statement (and/or, if applicable, the Shelf Registration Statement) to again be
declared effective or made usable in the case of (iv) above, or (5) if sooner,
upon the first date on which no Transfer Restricted Securities remain
outstanding, in the case of clauses (i) through (iv) above, the liquidated
damages payable with respect to the Transfer Restricted Securities as a result
of such clause (i), (ii), (iii) or (iv), as applicable, shall cease.

       All accrued liquidated damages shall be paid to the Holders entitled
thereto, in the manner provided for the payment of interest in the Indenture,
on each Interest Payment Date, as more fully set forth in the Indenture and the
Notes.  Notwithstanding the fact that any securities for which liquidated
damages are due cease to be Transfer Restricted Securities, all obligations of
the Issuers and the Guarantors to pay liquidated damages with respect to
securities that accrued prior to the time such securities ceased to be Transfer
Restricted Securities shall survive until such time as such obligations with
respect to such securities shall have been satisfied in full.

SECTION 6. REGISTRATION PROCEDURES

       (a)     Exchange Offer Registration Statement.   In connection with the
Exchange Offer, the Issuers and the Guarantors shall (x) comply with all
applicable provisions of Section 6(c) hereof, (y) use their reasonable best
efforts to effect such exchange and to permit the resale of Series B Notes by
Broker-Dealers that tendered in the Exchange Offer Series A Notes that such
Broker-Dealer acquired for its own account as a result of its market-making
activities or other trading activities (other than Series A Notes acquired





                                       6





<PAGE>   8



directly from the Issuers or any of their Affiliates) being sold in accordance
with the intended method or methods of distribution thereof, and (z) comply
with all of the following provisions:

             (i)          If, following the date hereof there has been
         announced a change in Commission policy with respect to exchange
         offers, such as the Exchange Offer, that, in the opinion of counsel to
         the Issuers and the Guarantors, raises a substantial question as to
         whether the Exchange Offer is permitted by applicable federal law, the
         Issuers and the Guarantors hereby agree to seek a no-action letter or
         other favorable decision from the Commission allowing the Issuers and
         the Guarantors to Consummate an Exchange Offer for such Transfer
         Restricted Securities.  The Issuers and the Guarantors hereby agree to
         use their reasonable best efforts in pursuing the issuance of such a
         decision to the Commission staff level.
        
             (ii)        As a condition to its participation in the Exchange
         Offer, each Holder of Transfer Restricted Securities (including,
         without limitation, any Holder who is a Broker-Dealer) shall furnish,
         upon the request of the Issuers, prior to the Consummation of the
         Exchange Offer, a written representation to the Issuers (which may be
         contained in the letter of transmittal contemplated by the Exchange
         Offer Registration Statement) to the effect that, at the time of
         Consummation of the Exchange Offer, (A) any Series B Notes received by
         such Holder will be acquired in the ordinary course of its business,
         (B) such Holder will have no arrangement or understanding with any
         person to participate in the distribution of the Series A Notes or the
         Series B Notes within the meaning of the Act, (C) if the Holder is not
         a Broker-Dealer or is a Broker-Dealer but will not receive Series B
         Notes for its own account in exchange for Series A Notes, neither the
         Holder nor any such other Person is engaged in or intends to
         participate in a distribution of the Series B Notes, and (D) that such
         Holder is not an Affiliate of the Issuers.  If the Holder is a
         Broker-Dealer that will receive Series B Notes for its own account in
         exchange for Series A Notes, it will represent that the Notes to be
         exchanged for the Series B Notes were acquired by it as a result of
         market-making activities or other trading activities, and will
         acknowledge that it will deliver a prospectus meeting the requirements
         of the Act in connection with any resale of such Series B Notes.  It
         is understood that, by acknowledging that it will deliver, and by
         delivering, a prospectus meeting the requirements of the Act in
         connection with any resale of such Series B Notes, the Holder is not
         admitting that it is an "underwriter" within the meaning of the Act.
        
              (iii)       Prior to effectiveness of the Exchange Offer
         Registration Statement, the Issuers and the Guarantors shall provide a
         supplemental letter to the Commission (A) stating that the Issuers and
         the Guarantors are registering the Exchange Offer in reliance on the
         position of the Commission enunciated in Exxon Capital Holdings
         Corporation(available May 13, 1988) and Morgan Stanley and Co., Inc.
         (available June 5, 1991), as interpreted in the Commission's letter to
         Shearman & Sterling dated July 2, 1993, and, if applicable, any
         no-action letter obtained pursuant to clause (i) above, (B) including
         a representation that neither the Issuers nor any Guarantor have
         entered into any arrangement or understanding with any Person to
         distribute the Series B Notes to be received in the Exchange Offer and
         that, to the best of the Issuers' and the Guarantors' information and
         belief, each Holder participating in the Exchange Offer is acquiring
         the Series B Notes in its ordinary course of business and has no
         arrangement or understanding with any Person to participate in the
         distribution of the Series B Notes received in the Exchange Offer and
         (C) any

         other undertaking or representation required by the Commission as set
         forth in any no-action letter obtained pursuant to clause (i) above,
         if applicable.
        
         (b) Shelf Registration Statement. In connection with the Shelf 
Registration Statement, the Issuers and the Guarantors shall:

                (i) comply with all the provisions of Section 6(c) hereof and
         use their reasonable best efforts to effect such registration to permit
         the sale of the Transfer Restricted Securities being sold in accordance
         with the intended method or methods of distribution thereof (as
         indicated in the information furnished to the Issuers pursuant to
         Section 4(b) hereof), and pursuant thereto the Issuers and the
         Guarantors will prepare and file with the Commission a Registration
         Statement relating to the registration on any appropriate form under
         the Act, which form shall be available for the sale of the Transfer
         Restricted Securities in accordance with the intended method or methods
         of distribution thereof within the time periods and otherwise in
         accordance with the provisions hereof, and
        
                (ii)     issue, upon the request of any Holder or purchaser of
         Series A Notes covered by any Shelf Registration Statement
         contemplated by this Agreement, Series B Notes having an aggregate
         principal amount equal to the aggregate principal amount of Series A
         Notes sold pursuant to the Shelf Registration Statement and
         surrendered to the Issuers for cancellation; the Issuers and the
         Guarantors shall register Series B Notes on the Shelf Registration
         Statement for this purpose and issue the Series B Notes to the
         purchaser(s) of securities subject to the Shelf Registration Statement
         in the names as such purchaser(s) shall designate.

         (c) General Provisions.  In connection with any Registration
Statement and any related Prospectus required by this Agreement, the Issuers
and the Guarantors shall, during the periods specified in Sections 3 and 4
hereof, as applicable:

               (i)        use their reasonable best efforts to keep such
         Registration Statement continuously effective and provide all
         requisite financial statements for the period specified in Section 3
         or 4 of this Agreement, as applicable.  Upon the occurrence of any
         event that would cause any such Registration Statement or the
         Prospectus contained therein (A) to contain an untrue statement of
         material fact or omit to state any material fact necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading or (B) not to be effective and usable for
         resale of Transfer Restricted Securities during the period required by
         this Agreement, the Issuers and the Guarantors shall file promptly an
         appropriate amendment to such Registration Statement or a supplement
         to the Prospectus, as applicable, curing such defect, and, in the case
         of an amendment, use their reasonable best efforts to cause such
         amendment to be declared effective as soon as practicable.

               (ii)       prepare and file with the Commission such amendments
         and post-effective amendments to the applicable Registration Statement
         as may be necessary to keep such Registration Statement effective for
         the applicable period set forth in Section 3 or 4 hereof, as the case
         may be; cause the Prospectus to be supplemented by any required
         Prospectus supplement, and as so supplemented to be filed pursuant to
         Rule 424 under the Act, and to comply fully with Rules





                                       8





<PAGE>   10



         424, 430A and 462, as applicable, under the Act in a timely manner; and
         comply with the provisions of the Act with respect to the disposition
         of all securities covered by such Registration Statement during the
         applicable period in accordance with the intended method or methods of
         distribution by the sellers thereof set forth in such Registration
         Statement or supplement to the Prospectus;

              (iii)       advise each Holder whose Transfer Restricted
         Securities have been included in a Shelf Registration Statement (in
         the case of the Shelf Registration Statement) and the Initial
         Purchaser promptly and, if requested by such Person, confirm such
         advice in writing, (A) when the Prospectus or any Prospectus
         supplement or post-effective amendment has been filed, and, with
         respect to any applicable Registration Statement or any post-effective
         amendment thereto, when the same has become effective, (B) of any
         request by the Commission for amendments to the Registration Statement
         or amendments or supplements to the Prospectus or for additional
         information relating thereto, (C) of the issuance by the Commission of
         any stop order suspending the effectiveness of the Registration
         Statement under the Act or of the suspension by any state securities
         commission of the qualification of the Transfer Restricted Securities
         for offering or sale in any jurisdiction, or the initiation of any
         proceeding for any of the preceding purposes, and (D) of the existence
         of any fact or the happening of any event that makes any statement of
         a material fact made in the Registration Statement, the Prospectus,
         any amendment or supplement thereto or any document incorporated by
         reference therein untrue, or that requires the making of any additions
         to or changes in the Registration Statement in order to make the
         statements therein not misleading, or that requires the making of any
         additions to or changes in the Prospectus in order to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading.  If at any time the Commission shall issue
         any stop order suspending the effectiveness of the Registration
         Statement, or any state securities commission or other regulatory
         authority shall issue an order suspending the qualification or
         exemption from qualification of the Transfer Restricted Securities
         under state securities or Blue Sky laws, the Issuers and the
         Guarantors shall use their reasonable best efforts to obtain the
         withdrawal or lifting of such order at the earliest possible time;

                 (iv)     subject to Section 6(c)(i), if any fact or event
         contemplated by Section 6(c)(iii)(D) hereof shall exist or have
         occurred, prepare a supplement or post-effective amendment to the
         Registration Statement or related Prospectus or any document
         incorporated therein by reference or file any other required document
         so that, as thereafter delivered to the purchasers of Transfer
         Restricted Securities, the Prospectus will not contain an untrue
         statement of a material fact or omit to state any material fact
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading;

                 (v)      furnish to each Holder whose Transfer Restricted
         Securities have been included in a Shelf Registration Statement (in
         the case of the Shelf Registration Statement) and the Initial
         Purchaser, before filing with the Commission, copies of any
         Registration Statement or any Prospectus included therein or any
         amendments or supplements to any such Registration Statement or
         Prospectus (including all documents incorporated by reference after
         the initial filing of such Registration Statement), which documents
         will be subject to the review and comment of such Persons, if any, for
         a period of at least five Business Days, and the Issuers will not file
         any such Registration Statement or Prospectus or any amendment or
         supplement to any such Registration





                                       9

         Statement or Prospectus (including all such documents incorporated by
         reference) to which such Persons shall reasonably object within five
         Business Days after the receipt thereof.  Such Persons  shall be deemed
         to have reasonably objected to such filing if such Registration
         Statement, amendment, Prospectus or supplement, as applicable, as
         proposed to be filed, contains an untrue statement of a material fact
         or omit to state any material fact necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading or fails to comply with the applicable requirements of
         the Act;

                 (vi)     promptly prior to the filing of any document that is
         to be incorporated by reference into a Registration Statement or
         Prospectus, provide copies of such document to each Holder whose
         Transfer Restricted Securities have been included in a Shelf
         Registration Statement (in the case of the Shelf Registration
         Statement) and the Initial Purchaser, make the Issuers' and the
         Guarantors' representatives available for discussion of such document
         and other customary due diligence matters, and include such information
         in such document prior to the filing thereof as such Persons may
         reasonably request;
        
                 (vii)    make available, at reasonable times, for inspection
         by each Holder whose Transfer Restricted Securities have been included
         in a Shelf Registration Statement (in the case of the Shelf
         Registration Statement) and the Initial Purchaser and any attorney or
         accountant retained by such Persons, all financial and other records,
         pertinent corporate documents of the Issuers and the Guarantors and
         cause the Issuers' and the Guarantors' officers, directors and
         employees to supply all information reasonably requested by any such
         Persons, attorney or accountant in connection with such Registration
         Statement or any post-effective amendment thereto subsequent to the
         filing thereof and prior to its effectiveness;

                 (viii)   if requested by any Holders whose Transfer Restricted
         Securities have been included in a Shelf Registration Statement (in
         the case of the Shelf Registration Statement) or the Initial
         Purchaser, promptly include in any Registration Statement or
         Prospectus, pursuant to a supplement or post-effective amendment if
         necessary, such information as such Persons may reasonably request to
         have included therein, including, without limitation, information
         relating to the "Plan of Distribution" of the Transfer Restricted
         Securities and the use of the Registration Statement or Prospectus for
         market-making activities; and make all required filings of such
         Prospectus supplement or post-effective amendment as soon as
         practicable after the Issuers are notified of the matters to be
         included in such Prospectus supplement or post-effective amendment;

                 (ix)     furnish to each Holder whose Transfer Restricted
         Securities have been included in a Shelf Registration Statement (in
         the case of the Shelf Registration Statement) and the Initial
         Purchaser, without charge, at least one copy of the Registration
         Statement, as first filed with the Commission, and of each amendment
         thereto, including all documents incorporated by reference therein and
         all exhibits (including exhibits incorporated therein by reference);

                 (x)      deliver to each Holder whose Transfer Restricted
         Securities have been included in a Shelf Registration Statement and
         the Initial Purchaser without charge, as many copies of the Prospectus
         (including each preliminary prospectus) and any amendment or
         supplement thereto as such Persons reasonably may request; the Issuers
         and the Guarantors hereby consent to the use (in





                                       10





<PAGE>   12



         accordance with law and subject to Section 6(d) hereof) of the
         Prospectus and any amendment or supplement thereto by each selling
         Person in connection with the offering and the sale of the Transfer
         Restricted Securities covered by the Prospectus or any amendment or
         supplement thereto and all market-making activities of the Initial
         Purchaser, as the case may be;

                (xi)     upon the request of any Holder whose Transfer
         Restricted Securities have been included in a Shelf Registration
         Statement (in the case of the Shelf Registration Statement) or the
         Initial Purchaser, enter into such agreements (including underwriting
         agreements) and make such representations and warranties and take all
         such other actions in connection therewith in order to expedite or
         facilitate the disposition of the Transfer Restricted Securities
         pursuant to any applicable Registration Statement contemplated by this
         Agreement as may be reasonably requested by such Person in connection
         with any sale or resale pursuant to any applicable Registration
         Statement.  In such connection, the Issuers and the Guarantors shall:
        
                (A) upon request of any such Person, furnish (or in the case of
         paragraphs (2) and (3), use their reasonable best efforts to cause to
         be furnished) to each Holder (in the case of the Shelf Registration
         Statement) and the Initial Purchaser, upon Consummation of the
         Exchange Offer or upon the effectiveness of the Shelf Registration
         Statement, as the case may be:

                          (1)  a certificate, dated such date, signed on behalf
                 of the Issuers by (x) the President or any Vice President and
                 (y) a principal financial or accounting officer of each of the
                 Issuers and each of the Guarantors, confirming, as of the date
                 thereof, the matters set forth in Sections 6(y), 9(a) and 9(b)
                 of the Purchase Agreement and such other similar matters as
                 such Person may reasonably request;

                          (2)  an opinion, dated the date of Consummation of
                 the Exchange Offer or the date of effectiveness of the Shelf
                 Registration Statement, as the case may be, of counsel for the
                 Issuers and the Guarantors covering matters similar to those
                 set forth in Sections 9(e) and (f) of the Purchase Agreement
                 and such other matters as such Person may reasonably request,
                 and in any event including a statement to the effect that such
                 counsel has participated in conferences with officers and
                 other representatives of the Issuers and the Guarantors,
                 representatives of the independent public accountants for the
                 Issuers and the Guarantors and have considered the matters
                 required to be stated therein and the statements contained
                 therein, although such counsel has not independently verified
                 the accuracy, completeness or fairness of such statements; and
                 that such counsel advises that, on the basis of the foregoing
                 (relying as to materiality to the extent such counsel deems
                 appropriate upon the statements of officers and other
                 representatives of the Issuers and the Guarantors) and without
                 independent check or verification), no facts came to such
                 counsel's attention that caused such counsel to believe that
                 the applicable Registration Statement, at the time such
                 Registration Statement or any post-effective amendment thereto
                 became effective and, in the case of the Exchange Offer
                 Registration Statement, as of the date of Consummation of the
                 Exchange Offer, 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





                                       11





<PAGE>   13



             statements therein not misleading, or that the Prospectus contained
             in such Registration Statement as of its date and, in the case of
             the opinion dated the date of Consummation of the Exchange Offer,
             as of the date of Consummation, contained an untrue statement of a
             material fact or omitted to state a material fact necessary in
             order to make the statements therein, in the light of the
             circumstances under which they were made, not misleading.  Without
             limiting the foregoing, such counsel may state further that such
             counsel assumes no responsibility for, and has not independently
             verified, the accuracy, completeness or fairness of the financial
             statements, notes and schedules and other financial data included
             in any Registration Statement contemplated by this Agreement or the
             related Prospectus; and

                    (3) a customary comfort letter, dated the date of
             Consummation of the Exchange Offer, or as of the date of
             effectiveness of the Shelf Registration Statement, as the case may
             be, from the Issuers' and the Guarantors' independent accountants,
             in the customary form and covering matters of the type customarily
             covered in comfort letters to underwriters in connection with
             underwritten offerings, and affirming the matters set forth in the
             comfort letters delivered pursuant to Section 9(h) of the Purchase
             Agreement; and
        
                (B) deliver such other documents and certificates as may be
             reasonably requested by such Persons to evidence compliance with
             the matters covered in clause (A) above and with any customary
             conditions contained in any agreement entered into by the Issuers
             and the Guarantors pursuant to this clause (xi);

                (xii)     prior to any public offering of Transfer Restricted
         Securities, cooperate with the selling Holders and their counsel in
         connection with the registration and qualification of the Transfer
         Restricted Securities under the securities or Blue Sky laws of such
         jurisdictions as the selling Holders may request and do any and all
         other acts or things necessary or advisable to enable the disposition
         in such jurisdictions of the Transfer Restricted Securities covered by
         the applicable Registration Statement; provided that neither the
         Issuers nor any Guarantor shall be required to register or qualify as
         a foreign corporation where it is not now so qualified or to take any
         action that would subject it to the service of process in suits or to
         taxation, other than as to matters and transactions relating to the
         Registration Statement, in any jurisdiction where it is not now so
         subject;

                (xiii)    in connection with any sale of Transfer Restricted
         Securities that will result in such securities no longer being
         Transfer Restricted Securities, cooperate with the Holders to
         facilitate the timely preparation and delivery of certificates
         representing Transfer Restricted Securities to be sold and not bearing
         any restrictive legends; and to register such Transfer Restricted
         Securities in such denominations and such names as the selling Holders
         may request at least two Business Days prior to such sale of Transfer
         Restricted Securities;

                (xiv)      use their reasonable best efforts to cause the
         disposition of the Transfer Restricted Securities covered by the
         Registration Statement to be registered with or approved by such other

                (xvi)       otherwise use their reasonable best efforts to
         comply with all applicable rules and regulations of the Commission, and
         make generally available to their security holders with regard to any
         applicable Registration Statement, as soon as practicable, a
         consolidated earnings statement meeting the requirements of Rule 158
         (which need not be audited) covering a twelve-month period beginning
         after the effective date of the Registration Statement (as such term is
         defined in Rule 158(c) under the Act);

                (xvii)      cause the Indenture to be qualified under the TIA

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

                (xviii)     provide promptly to each Holder and the Initial
         Purchaser, upon request, each document filed with the Commission
         pursuant to the requirements of Section 13 or Section 15(d) of the
         Exchange Act.

       (d)     Restrictions on Holders.   Each Holder agrees by acquisition of

6(c)(iii)(D) hereof (in each case, a "Suspension Notice"), such Person will
forthwith discontinue disposition of Transfer Restricted Securities pursuant to
the applicable Registration Statement until (i) such Person has received copies
of the supplemented or amended Prospectus contemplated by Section 6(c)(iv)
hereof, or (ii) such Person is advised in writing by the Issuers that the use
of the Prospectus may be resumed, and has received copies of any additional or
supplemental filings that are incorporated by reference in the Prospectus (in
each case, the "Recommencement Date").  Each Person receiving a Suspension
Notice hereby agrees that it will either (i) destroy any Prospectuses, other
than permanent file copies, then in such Person's possession which have been
replaced by the Issuers with more recently dated Prospectuses or (ii) deliver
to the Issuers (at the Issuers' expense) all copies, other than permanent file
copies, then in such Person's possession of the Prospectus covering such
Transfer Restricted Securities that was current at the time of receipt of the
Suspension Notice.  The time period regarding the effectiveness of such
Registration Statement set forth in Section 3 or 4 hereof, as applicable, shall
be extended by a number of days equal to the number of days in the period from
and including the date of delivery of the Suspension Notice to the date of

SECTION 7. REGISTRATION EXPENSES

      (a)      All expenses incident to the Issuers' and the Guarantors'

(v) all application and filing fees in connection with listing the Series B

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

       (b)     In connection with any Registration Statement required by this

Shelf Registration Statement, as applicable, for the reasonable fees and
disbursements of not more than one counsel, who shall be chosen by the Holders
of a majority in principal amount of the Transfer Restricted Securities for
whose benefit such Registration Statement is being prepared.

SECTION 8. INDEMNIFICATION

       (a)     The Issuers and the Guarantors, jointly and severally, agree to
indemnify and hold harmless each Holder, its directors, officers and each
Person, if any, who controls such Holder (within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act), from and against any and all
losses, claims, damages, liabilities, judgments, (including, without
limitation, any legal or other expenses incurred in connection with
investigating or defending any matter, including any action that could give
rise to any such losses, claims, damages, liabilities or judgments) caused by
any untrue statement or alleged untrue statement of a material fact contained
in any Registration Statement, preliminary prospectus or Prospectus (or any
amendment or supplement thereto) provided by the Issuers to any Holder or any
prospective purchaser of Series B Notes or registered Series A Notes, or caused
by any omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not
misleading, except insofar as such losses, claims, damages, liabilities or
judgments are caused by an untrue statement or omission or alleged untrue
statement or omission that is based upon information relating to any of the
Holders furnished in writing to the Issuers by any of the Holders.





                                       14





<PAGE>   16





      (b)      Each Holder of Transfer Restricted Securities agrees, severally
and not jointly, to indemnify and hold harmless each of the Issuers and the
Guarantors, its directors and officers, and each person, if any, who controls
(within the meaning of Section 15 of the Act or Section 20 of the Exchange Act)
such Issuer or Guarantor, to the same extent as the foregoing indemnity from
the Issuers and the Guarantors set forth in Section 8(a) hereof, but only with
reference to information relating to such Holder furnished in writing to the
Issuers and the Guarantors by such Holder expressly for use in any Registration
Statement.  In no event shall any Holder, its directors, officers or any Person
who controls such Holder be liable or responsible for any amount in excess of
the amount by which the total amount received by such Holder with respect to
its sale of Transfer Restricted Securities pursuant to a Registration Statement
exceeds (i) the amount paid by such Holder for such Transfer Restricted
Securities and (ii) the amount of any damages that such Holder, its directors,
officers or any Person who controls such Holder has otherwise been required to
pay by reason of such untrue or alleged untrue statement or omission or alleged
omission.

      (c)      In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying person") in
writing, and the indemnifying party shall assume the defense of such action,
including the employment of counsel reasonably satisfactory to the indemnified
party and the payment of all fees and expenses of such counsel, as incurred
(except that, in the case of any action in respect of which indemnity may be
sought pursuant to both Sections 8(a) and 8(b), a Holder shall not be required
to assume the defense of such action pursuant to this Section 8(c), but may
employ separate counsel and participate in the defense thereof, but the fees
and expenses of such counsel, except as provided below, shall be at the expense
of the Holder).  Any indemnified party shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of the indemnified party,
unless (i) the employment of such counsel shall have been specifically
authorized in writing by the indemnifying party, (ii) the indemnifying party
shall have failed to assume the defense of such action or employ counsel
reasonably satisfactory to the indemnified party or (iii) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the indemnifying party, and the indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the indemnified party).
In any such case, the indemnifying party shall not, in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys
(in addition to any local counsel) for all indemnified parties and all such
fees and expenses shall be reimbursed as they are incurred.  Such firm shall be
designated in writing by a majority of the Holders, in the case of the parties
indemnified pursuant to Section 8(a), and by the Issuers and the Guarantors, in
the case of parties indemnified pursuant to Section 8(b). The indemnifying
party shall indemnify and hold harmless the indemnified party from and against
any and all losses, claims, damages, liabilities and judgments by reason of any
settlement of any action (i) effected with its written consent or (ii) effected
without its written consent if the settlement is entered into more than twenty
Business Days after the indemnifying party shall have received a request from
the indemnified party for reimbursement for the fees and expenses of counsel
(in any case where such fees and expenses are at the expense of the
indemnifying party) and, prior to the date of such settlement, the indemnifying
party shall have failed to comply with such reimbursement request.   No
indemnifying party shall, without the prior written consent of the indemnified





                                       15





<PAGE>   17



party, effect any settlement or compromise of, or consent to the entry of
judgment with respect to, any pending or threatened action in respect of which
the indemnified party is or could have been a party and indemnity or
contribution may be or could have been sought hereunder by the indemnified
party, unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability on claims
that are or could have been the subject matter of such action and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of the indemnified party.

       (d)     To the extent that the indemnification provided for in this
Section 8 is unavailable to an indemnified party in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Issuers and the Guarantors, on the one hand, and the Holders, on the other
hand, from their sale of Transfer Restricted Securities or (ii) if the
allocation provided by clause 8(d)(i) is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause 8(d)(i) hereof but also the relative fault of the Issuers
and the Guarantors, on the one hand, and of the Holder, on the other hand, in
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations.  The relative fault of the Issuers and the
Guarantors, on the one hand, and of the Holder, 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 Issuers and the
Guarantors, on the one hand, or by the Holder, on the other hand, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.  The amount paid or payable by
an indemnified party as a result of the losses, claims, damages, liabilities or
judgments referred to above shall be deemed to include, subject to the
limitations set forth in the second paragraph of Section 8(a), any legal or
other fees or expenses reasonably incurred by such indemnified party in
connection with investigating or defending any matter, including any action
that could have given rise to such losses, claims, damages, liabilities or
judgments.

       The Issuers, the Guarantors and each Holder agree that it would not be
just and equitable if contribution pursuant to this Section 8(d) 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 in the immediately
preceding paragraph. Notwithstanding the provisions of this Section 8, no
Holder, its directors, its officers or any Person, if any, who controls such
Holder shall be required to contribute, in the aggregate, any amount in excess
of the amount by which the total received by such Holder with respect to the
sale of Transfer Restricted Securities pursuant to a Registration Statement
exceeds (i) the amount paid by such Holder for such Transfer Restricted
Securities and (ii) the amount of any damages which such Holder has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Holders' obligations to contribute pursuant to this
Section 8(d) are several in proportion to the respective principal amount of
Transfer Restricted Securities held by each Holder hereunder and not joint.

<PAGE>   18




      (e)      The Issuers and the Guarantors agree that the indemnity and
contribution provisions of this Section 8 shall apply to the Initial Purchaser
to the same extent, on the same conditions, as it applies to Holders.

SECTION 9. RULE 144A AND RULE 144

       The Issuers and the Guarantors agrees with each Holder, for so long as
any Transfer Restricted Securities remain outstanding and during any period in
which the Issuers (i) are not subject to Section 13 or 15(d) of the Exchange
Act, to make available, upon request of any Holder, to such Holder or
beneficial owner of Transfer Restricted Securities in connection with any sale
thereof and any prospective purchaser of such Transfer Restricted Securities
designated by such Holder or beneficial owner, the information required by Rule
144A(d)(4) under the Act in order to permit resales of such Transfer Restricted
Securities pursuant to Rule 144A, and (ii) are subject to Section 13 or 15(d)
of the Exchange Act, to make all filings required thereby in a timely manner in
order to permit resales of such Transfer Restricted Securities pursuant to Rule
144.

SECTION 10. MISCELLANEOUS

      (a)      Remedies.   The Issuers and the Guarantors acknowledge and agree
that any failure by the Issuers and the Guarantors to comply with their
obligations under Sections 3 and 4 hereof may result in material irreparable
injury to the Initial Purchaser or the Holders for which there is no adequate
remedy at law, that it will not be possible to measure damages for such
injuries precisely and that, in the event of any such failure, the Initial
Purchaser or any Holder may obtain such relief as may be required to
specifically enforce the Issuers' and the Guarantors' obligations under
Sections 3 and 4 hereof.  The Issuers and the Guarantors further agree to waive
the defense in any action for specific performance that a remedy at law would
be adequate.

      (b)      No Inconsistent Agreements.  None of the Issuers or the
Guarantors will, on or after the date of this Agreement, enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof. None of the Issuers or the Guarantors has previously entered
into any agreement granting any registration rights with respect to its
securities to any Person.  The rights granted to the Holders hereunder do not
in any way conflict with and are not inconsistent with the rights granted to
the holders of the Issuers' or any Guarantor's securities under any agreement
in effect on the date hereof.

      (c)      Amendments and Waivers.   The provisions of this Agreement may
not be amended, modified or supplemented, and waivers or consents to or
departures from the provisions hereof may not be given unless (i) in the case
of Section 5 hereof and this Section 10(c)(i), the Issuers have obtained the
written consent of Holders of all outstanding Transfer Restricted Securities,
and (ii) in the case of all other provisions hereof, the Issuers have obtained
the written consent of Holders of a majority of the outstanding principal
amount of Transfer Restricted Securities (excluding Transfer Restricted
Securities held by the Issuers or their Affiliates).  Notwithstanding the
foregoing, a waiver or consent to departure from the provisions hereof that
relates exclusively to the rights of Holders whose Transfer Restricted
Securities are being tendered pursuant to the Exchange Offer, and that does not
affect directly or indirectly the rights of other Holders whose Transfer
Restricted Securities are not being tendered pursuant to such Exchange Offer,





                                       17





<PAGE>   19



may be given by the Holders of a majority of the outstanding principal amount
of Transfer Restricted Securities subject to such Exchange Offer.

      (d)      Third Party Beneficiary.   The Holders shall be third party
beneficiaries to the agreements made hereunder between the Issuers and the
Guarantors, on the one hand, and the Initial Purchaser, on the other hand, and
shall have the right to enforce such agreements directly to the extent they may
deem such enforcement necessary or advisable to protect its rights or the
rights of Holders hereunder.

      (e)      Notices.   All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air

parties, including, without limitation, and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Transfer Restricted
Securities in violation of the terms hereof or of the Purchase Agreement or the
Indenture.  If any transferee of any Holder shall acquire Transfer Restricted
Securities in any manner, whether by operation of law or otherwise, such
Transfer Restricted Securities shall be held subject to all of the terms of
this Agreement, and by taking and holding such Transfer Restricted Securities
such Person shall be conclusively deemed to have agreed to be bound by and to

The Leverage Ratio used to compute the Applicable Commitment Fee for any date
referred to in clause (ii) above shall be the Leverage Ratio set forth in the
Compliance Certificate most recently delivered by the Company to the
Administrative Agent on or prior to such day pursuant to clause (c) of Section
7.1.1.  Changes in the Applicable Commitment Fee resulting from a change in the
Leverage Ratio shall become effective (as of the first day following the Fiscal
Quarter in respect of which such Compliance Certificate was required to be
delivered) upon delivery by the Company to the Administrative Agent of a new
Compliance Certificate pursuant to clause (c) of Section 7.1.1.  In the event
such Compliance Certificate indicates a Leverage Ratio that would result in an
Applicable Commitment Fee which is greater or lesser than the Applicable
Commitment Fee theretofore in effect, then (A) such greater or lesser
Applicable Commitment Fee shall be deemed to have been in effect for all
purposes of this Agreement from the first day following the Fiscal Quarter in
respect of which such Compliance Certificate was required to be delivered by
the Company to the Administrative Agent pursuant to clause (c) of Section 7.1.1
and (B) if any Borrower shall have theretofore made any payment of commitment
fees in respect of the period from the first day following the Fiscal Quarter
in respect of which such Compliance Certificate was required to be delivered by
the Company to the Administrative Agent pursuant to clause (c) of Section
7.1.1, then, on the next Quarterly Payment Date, either (x) if the new
Applicable Commitment Fee is greater than the Applicable Commitment Fee
theretofore in effect, such Borrower shall pay, as a supplemental payment of
commitment fees, an amount which equals the difference between the amount of
commitment fees that would otherwise have been paid based on such new Leverage
Ratio and the amount of such commitment fees actually so paid, or (y) if the
new Applicable Commitment Fee is less than the Applicable Commitment Fee





                                       7

theretofore in effect, an amount shall be deducted from the interest on
Committed Revolving Loans and commitment fees and Letter of Credit fees under
the first sentence of Section 3.3.3 then otherwise payable in an amount which
equals the difference between the amount of commitment fees so paid and the
amount of commitment fees that would otherwise have been paid based on such new
Leverage Ratio (or, if no such payment is owed by such Borrower to the
Revolving Lenders on such next Quarterly Payment Date, or if such amount owed
by such Borrower is less than such difference, the Revolving Lenders shall pay
to such Borrower on such next Quarterly Payment Date the amount of such
difference less the amount, if any, owed by such Borrower to such Lenders on
such Quarterly Payment Date); provided that, if the Company shall fail to
deliver a Compliance Certificate within the number of days required pursuant to
clause (c) of Section 7.1.1 (without giving effect to any grace period), the
Applicable Commitment Fee from and including the first day after the date on
which such Compliance Certificate was required to be delivered to but not
including the date the Company delivers to the Administrative Agent an
appropriately completed Compliance Certificate shall conclusively equal the
highest Applicable Commitment Fee set forth above.

                      "Applicable Margin" means at all times during the
applicable periods set forth below,

                             (a)  with respect to the unpaid principal amount
                      of each Term-B Loan maintained as a (i) Base Rate Loan,
                      1.25% per annum and (ii) LIBO Rate Loan, 2.50% per annum;

                      of each Term-C Loan maintained as a (i) Base Rate Loan,
                      1.50% per annum, and (ii) LIBO Rate Loan, 2.75% per
                      annum;

                             (c)  from the Closing Date through (but excluding)
                      the date upon which the Compliance Certificate for the
                      second full Fiscal Quarter ending after the Closing Date
                      is delivered by the Company to the Administrative Agent
                      pursuant to clause (c) of Section 7.1.1, with respect to
                      the unpaid principal amount of each (i) Swing Line Loan
                      (which shall be borrowed and maintained only as a U.S.
                      Dollar denominated Base Rate Loan) and each Committed
                      Revolving Loan and Term-A Loan maintained as a Base Rate
                      Loan, 1.00% per annum, and (ii) Committed Revolving Loan
                      and Term-A Loan maintained as a LIBO Rate Loan, 2.25% per
                      annum; and

first day following the Fiscal Quarter in respect of which such Compliance
Certificate was required to be delivered) upon delivery by the Company to the

respect of which such Compliance Certificate was required to be delivered by
the Company to the Administrative Agent pursuant to clause (c) of Section 7.1.1
and (B) if any Borrower shall have theretofore made any payment of interest in
respect of Swing Line Loans, Committed Revolving Loans or Term-A Loans, or of

such case in respect of the period from the first day following the Fiscal
Quarter in respect of which such Compliance Certificate was required to be
delivered to the actual date of delivery of such Compliance Certificate, then,
on the next Quarterly Payment Date, either (x) if the new Applicable Margin is
greater than the Applicable Margin theretofore in effect, such Borrower shall
pay as a supplemental payment of interest and/or Letter of Credit fees, an
amount which equals the difference between the amount of interest and Letter of
Credit fees that would otherwise have been paid based on such new Leverage
Ratio and the amount of such interest and Letter of Credit fees actually so
paid, or (y) if the new Applicable Margin is less than the Applicable Margin
theretofore in effect, an amount shall be deducted from the interest on
Committed Revolving Loans, commitment fees and Letter of Credit fees (in the
case of differences in respect of interest on Committed Revolving Loans and
Letter of Credit fees) or from the interest on Term-A Loans (in the case of
differences in respect of interest on Term-A Loans) thereafter payable by such
Borrower in an amount which equals the difference between the amount of
interest and Letter of Credit fees so paid and the amount of interest and
Letter of Credit fees that would otherwise have been paid based on such new
Leverage Ratio (or, if no payment by such Borrower to the Revolving Lenders or
Term-A Lenders, as the case may be, will thereafter accrue hereunder, or if the
amount that so accrues is less than such difference, the Revolving Lenders or
the Term-A Lenders, as the case may be, will promptly pay to such Borrower an
amount equal to such difference less the amount, if any, of such accrued and
unpaid payments); provided, that if the Company shall fail to deliver a
Compliance Certificate within the number of days required pursuant to clause
(c) of Section 7.1.1 (without giving effect to any grace period), the
Applicable Margin for all Committed Revolving Loans, Term-A Loans and Letters
of Credit from and including the first day after the date on which such
Compliance Certificate was required to be delivered to but not including the

shall conclusively equal the highest Applicable Margin for the relevant type of
Loan set forth in clause (d) above.

a fund that invests in bank loans, any other fund that invests in bank loans

                      Revolving Loan Commitments a pro rata portion (based upon
                      the Total Revolving Loan

                      Commitment Amount at such time) of any such additional
                      Revolving Loan Commitment.  Alternatively, any Lender may
                      commit to provide the full amount of the requested
                      additional Revolving Loan Commitment and then offer
                      portions of such additional Revolving Loan Commitment to
                      the other Lenders or other financial institutions,
                      subject to the proviso in the immediately preceding
                      sentence.  Nothing contained in this clause (g) or
                      otherwise in this Agreement is intended to commit any
                      Lender or any Agent to provide any portion of any such
                      additional Revolving Loan Commitments.  If and to the
                      extent that any Lenders and/or other financial
                      institutions agree, in their sole discretion, to provide
                      any such additional Revolving Loan Commitments, (i) the
                      Total Revolving Loan Commitment Amount and the Revolving
                      Loan U.S. Dollar Commitment Amount or the Revolving Loan
                      Foreign Currency Commitment Amount, as the case may be,
                      shall be increased by the amount of the additional
                      Revolving Loan U.S. Dollar Commitments or Revolving Loan
                      Foreign Currency Commitments, as the case may be, agreed
                      to be so provided, (ii) the Percentages of the respective
                      Lenders in respect of the Revolving Loan U.S. Dollar
                      Commitment and/or Revolving Loan Foreign Currency
                      Commitments, as the case may be, shall be proportionally
                      adjusted, as applicable, (iii) at such time and in such
                      manner as the Company and the Syndication Agent shall
                      agree (it being understood that the Company and the
                      Agents will use all commercially reasonable efforts to
                      avoid the prepayment or assignment of any LIBO Rate Loan
                      on a day other than the last day of the Interest Period
                      applicable thereto), the Lenders shall assign and assume
                      outstanding Committed Revolving Loans and participations
                      in outstanding Letters of Credit so as to cause the
                      amount of such Committed Revolving Loans and
                      participations in Letters of Credit held by each Lender
                      to conform to the respective percentages of the
                      applicable Revolving Loan Commitments of the Lenders and
                      (iv) the Company shall execute and deliver any additional
                      Notes or other amendments or modifications to this
                      Agreement or any other Loan Document as the Agents may
                      reasonably request.

of any Foreign Borrower other than the Initial Foreign Borrowers, compliance by
the applicable Foreign Borrower with the terms of Section 5.3), from time to
time on any Business Day occurring concurrently with (or after) the Closing
Date but prior to the Revolving Loan Commitment Termination Date, an Issuer in
respect of a Currency will (i) issue one or more standby or commercial letters
of credit denominated in the applicable

Company or any of its Subsidiaries in the Stated Amount requested by the
applicable Borrower on such day, or (ii) extend the Stated Expiry Date of an
existing standby or commercial Letter of Credit previously issued hereunder to
a date not later than the earlier of (x) the Business Day immediately preceding
the sixth anniversary of the Closing Date and (y) the first anniversary of the
date of such extension; provided that, notwithstanding the terms of this clause
(y), a Letter of Credit may, if required by the beneficiary thereof, contain
"evergreen" provisions pursuant to which the Stated Expiry Date shall be
automatically extended, unless notice to the contrary shall have been given to
the beneficiary by the applicable Issuer or the account party of such Letter of
Credit more than a specified period prior to the then existing Stated Expiry
Date.

                      (b)    Each Existing Letter of Credit shall for purposes
of this Agreement be deemed to be a "Letter of Credit" issued hereunder on the
Closing Date.

                      SECTION 2.1.4.  Lenders Not Permitted or Required to Make
the Loans.  No Lender shall be permitted or required to make, and the
applicable Borrower shall not request any Lender to make, any of the following
Loans to the extent prohibited by this Section 2.1.4:

                      requested to be made by any applicable Borrower if,
                      after giving effect thereto, the aggregate original
                      principal amount (calculated at the U.S. Dollar
                      Equivalent thereof on the Closing Date in the case of any
                      Term-A Australian Dollar Loan or Term-A Lira Loan) of all
                      Term-A Australian Dollar Loans, Term-A Lira Loans, Term-A
                      U.S. Dollar Loans, Term-B Loans or Term-C Loans (as the
                      case may be) of such Lender would exceed such Lender's
                      Percentage of the Term-A Loan Australian Dollar
                      Commitment Amount (in the case of Term-A Australian
                      Dollar Loans), the Term-A Loan Lira Commitment Amount (in
                      the case of Term-A Lira Loans), the Term-A Loan U.S.

                      Dollar Loans), the Term-B Loan Commitment Amount (in the
                      case of Term-B Loans) or the Term-C Loan Commitment
                      Amount (in the case of Term-C Loans).

                             (b)  No U.S. Dollar Revolving Loan shall be made
                      by any Lender, or requested to be made by the Company if,
                      after giving effect thereto, the aggregate outstanding
                      principal amount of (i) all U.S. Dollar Revolving Loans

                      of such Lender, plus (ii) such Lender's Percentage in
                      respect of the Revolving Loan U.S. Dollar Commitment of
                      the aggregate amount of all U.S. Dollar Letter of Credit
                      Outstandings plus (iii) such Lender's Percentage in
                      respect of the Revolving Loan U.S. Dollar Commitment of
                      the outstanding principal amount of all Swing Line Loans,
                      would exceed such Lender's Percentage of the Revolving
                      Loan U.S. Dollar Commitment Amount.

                             (c)  No Committed Foreign Currency Revolving Loan
                      under any Revolving Loan Foreign Currency Commitment
                      shall be made by any Lender, or requested to be made by
                      any Foreign Borrower if, after giving effect thereto, the
                      U.S. Dollar Equivalent of the aggregate outstanding
                      principal amount of (i) all such Committed Foreign
                      Currency Revolving Loans of such Lender under such
                      Commitment plus (ii) such Lender's Percentage in respect
                      of such Revolving Loan Foreign Currency Commitment of the
                      aggregate amount of all Foreign Currency Letter of Credit
                      Outstandings in respect of the applicable Commitment,
                      would exceed such Lender's Percentage in respect of the
                      Revolving Loan Foreign Currency Commitment Amount
                      applicable to such Commitment.

                             (d)  No Swing Line Loan shall be made by the Swing
                      Line Lender, or requested to be made by the Company if,
                      after giving effect thereto, the aggregate outstanding
                      principal amount of all Swing Line Loans would exceed the
                      lesser of (i) the then existing Swing Line Loan
                      Commitment Amount and (ii) an amount equal to the then
                      existing Revolving Loan U.S. Dollar Commitment Amount
                      less the sum of (x) the aggregate outstanding principal
                      amount of all U.S. Dollar Revolving Loans and (y) the
                      U.S. Dollar Letter of Credit Outstandings.

                      SECTION 2.1.5.  Issuer Not Permitted or Required to Issue
Letters of Credit.  No Issuer in respect of any Currency shall be permitted or
required to issue any Letter of Credit if, after giving effect thereto, (i) the
Letter of Credit Outstandings would exceed the then existing Letter of Credit
Commitment Amount or (ii) the Letter of Credit Outstandings in respect of the
applicable Tranche would exceed (x) the then existing Revolving Loan Commitment
Amount in respect of such Tranche less (y) the sum of (A) the aggregate amount
of all U.S. Dollar Revolving Loans or Committed Foreign Currency Revolving
Loans in the applicable Currency, as the case may be, and (B) in the case of
U.S. Dollar Letters of Credit only, the aggregate amount of all Swing Line
Loans.

                      SECTION 2.2.  Optional Reduction of the Revolving Loan
Commitment Amount.  The Company may, from time to time on any Business Day
occurring after the Closing Date, voluntarily reduce any Revolving Loan
Commitment Amount; provided, however, that all such reductions shall require at
least three Business Days' prior notice to the Administrative Agent and any
partial reduction of any Revolving Loan Commitment Amount shall be in an
aggregate amount of $500,000 or any larger integral multiple of $100,000.  Any
such reduction of any Revolving Loan Commitment Amount which reduces such
Revolving Loan Commitment Amount below the Letter of Credit Commitment Amount
with respect to the same Currency (or, in the case of the Revolving Loan U.S.
Dollar Commitment only, the Swing Line Loan Commitment Amount) shall result in
an automatic and corresponding reduction of such Letter of Credit Commitment
Amount (or the Swing Line Loan Commitment Amount, as the case may be) to an
aggregate amount not in excess of the applicable Revolving Loan Commitment
Amount, as so reduced, without any further action on the part of the applicable
Issuer (or the Swing Line Lender, if applicable); provided, that any such
reduction in any such Letter of Credit Commitment Amount or the Swing Line Loan
Commitment Amount shall be reinstated to the extent that, whether pursuant to
clause (g) of Section 2.1.2, Section 2.5 or otherwise, the corresponding
Revolving Loan Commitment Amount is thereafter increased.

                      SECTION 2.3.  Borrowing Procedures and Funding
Maintenance.  Committed Loans (other than Swing Line Loans) shall be made by
the Lenders in accordance with Section 2.3.1, and Swing Line Loans shall be
made by the Swing Line Lender in accordance with Section 2.3.2.

                      SECTION 2.3.1.  Term Loans and Committed Revolving Loans.
By delivering the appropriate Committed Loan Borrowing Request to the
Administrative Agent on or before 12:00 noon, New York time, on a Business Day,
a Borrower may from time to time irrevocably request, on not less than one
Business Day's notice (in the case of Base Rate Loans) or three Business Days'
notice (in the case of LIBO Rate Loans) nor more than five Business Days'
notice (in the case of any Committed Loans), that a Committed Borrowing be made
in an aggregate amount of $1,000,000 (or, in the case of Committed Foreign
Currency Revolving Loans, the multiple of 100,000 units of the Currency of such
Loans the U.S. Dollar Equivalent of which is nearest to $1,000,000) or any
larger integral multiple of $500,000 (or, in the case of Committed Foreign
Currency Revolving Loans, the multiple of 50,000 units of the Currency of such
Loans the U.S. Dollar Equivalent of which is nearest to $500,000), or in the
unused amount of the applicable Commitment.  No Committed Loan Borrowing
Request shall be required, and the minimum aggregate amounts specified





                                       66
<PAGE>   75
under this Section 2.3.1 shall not apply, in the case of U.S. Dollar Revolving
Loans made under clause (b) of Section 2.3.2 to refund Refunded Swing Line
Loans or Committed Revolving Loans deemed made under Section 2.8.2 in respect
of unreimbursed Disbursements.  On the terms and subject to the conditions of
this Agreement, each Committed Borrowing shall be comprised of the type of
Committed Loans, shall be made in the Currency, and shall be made on the
Business Day, specified in such Committed Loan Borrowing Request.  As to U.S.
Dollar Loans, on or before 11:00 a.m., New York time, on such Business Day each
Lender shall deposit with the Administrative Agent same day funds in the
applicable Currency in an amount equal to such Lender's Percentage of the
requested Committed Borrowing.  Such deposit will be made to an account which
the Administrative Agent shall specify from time to time by notice to the
Lenders.  As to Committed Loans in any Foreign Currency, on or before 11:00
a.m. (local time in the country in which the applicable Foreign Borrower is
located), on the Business Day specified in such Committed Loan Borrowing
Request, each relevant Lender shall deposit same day funds in the applicable
Currency in an amount equal to such Lender's Percentage of the requested
Committed Borrowing at such account as shall be designated by the
Administrative Agent.  To the extent funds are received from the Lenders, the
Administrative Agent shall make such funds available to the applicable Borrower
by wire transfer to the accounts such Borrower shall have specified in its
Committed Loan Borrowing Request.  No Lender's obligation to make any Committed
Loan shall be affected by any other Lender's failure to make any Committed
Loan.

                      SECTION 2.3.2.  Swing Line Loans.  (a)  By telephonic
notice, promptly followed (within one Business Day) by the delivery of a
confirming Committed Loan Borrowing Request, to the Swing Line Lender and the
Administrative Agent on or before 3:00 p.m., New York City time, on the
Business Day the proposed Swing Line Loan is to be made, the Company may from
time to time irrevocably request that a Swing Line Loan be made by the Swing
Line Lender in a minimum principal amount of $500,000 or any larger integral
multiple of $100,000.  All Swing Line Loans shall be made in U.S. Dollars as
Base Rate Loans and shall not be entitled to be converted into LIBO Rate Loans.
Upon receipt of notice from the Administrative Agent confirming the amount of
the requested Borrowing, the proceeds of each Swing Line Loan shall be made
available by the Swing Line Lender, by 3:30 p.m., New York City time, on the
Business Day telephonic notice is received by it as provided in this clause
(a), to the Company by wire transfer to the account the Company shall have
specified in its notice therefor.





                                       67
<PAGE>   76
                      (b)  If any Default shall occur and be continuing, each
Lender with a Revolving Loan U.S. Dollar Commitment (other than the Swing Line
Lender) irrevocably agrees that it will, at the request of the Swing Line
Lender and upon notice from the Administrative Agent, unless such Swing Line
Loan shall have been earlier repaid in full, make a U.S. Dollar Revolving Loan
(which shall initially be funded as a Base Rate Loan) in an amount equal to
such Lender's Percentage in respect of the Revolving Loan U.S. Dollar
Commitments of the aggregate principal amount of all such Swing Line Loans then
outstanding (such outstanding Swing Line Loans hereinafter referred to as the
"Refunded Swing Line Loans"); provided, that the Swing Line Lender shall not
request, and no Lender with a Revolving Loan U.S. Dollar Commitment shall make,
any Refunded Swing Line Loan if, after giving effect to the making of such
Refunded Swing Line Loan, the sum of all Swing Line Loans and U.S. Dollar
Revolving Loans made by such Lender, plus such Lender's Percentage in respect
of the Revolving Loan U.S. Dollar Commitments of the aggregate amount of all
U.S. Dollar Letter of Credit Outstandings, would exceed such Lender's
Percentage of the then existing Revolving Loan U.S. Dollar Commitment Amount.
On or before 11:00 a.m. (New York City time) on the first Business Day
following receipt by each Lender of a request to make U.S. Dollar Revolving
Loans as provided in the preceding sentence, each such Lender with a Revolving
Loan U.S. Dollar Commitment shall deposit in an account specified by the Swing
Line Lender the amount so requested in same day funds and such funds shall be
applied by the Swing Line Lender to repay the Refunded Swing Line Loans.  At
the time the aforementioned Lenders make the above referenced U.S. Dollar
Revolving Loans, the Swing Line Lender shall be deemed to have made, in
consideration of the making of the Refunded Swing Line Loans, a U.S. Dollar
Revolving Loan in an amount equal to the Swing Line Lender's Percentage in
respect of the Revolving Loan U.S. Dollar Commitment of the aggregate principal
amount of the Refunded Swing Line Loans.  Upon the making (or deemed making, in
the case of the Swing Line Lender) of any U.S. Dollar Revolving Loans pursuant
to this clause (b), the amount so funded shall become outstanding as a U.S.
Dollar Revolving Loan of such Lender and shall no longer be a Swing Line Loan.
All interest payable with respect to any U.S. Dollar Revolving Loans made (or
deemed made, in the case of the Swing Line Lender) pursuant to this clause (b)
shall be appropriately adjusted to reflect the period of time during which the
Swing Line Lender had outstanding Swing Line Loans in respect of which such
U.S. Dollar Revolving Loans were made.  Each Lender's obligation (in the case
of Lenders with a Revolving Loan U.S. Dollar Commitment) to make the U.S.
Dollar Revolving Loans referred to in this clause (b) shall be absolute and
unconditional and shall not be affected by any circumstance, including, without
limitation, (i) any set-off, counterclaim, recoupment, defense or other right
which





                                       68
<PAGE>   77
such Lender may have against the Swing Line Lender, the Company or any other
Person for any reason whatsoever; (ii) the occurrence or continuance of any
Default; (iii) any adverse change in the condition (financial or otherwise) of
the Company or any other Obligor; (iv) the acceleration or maturity of any
Loans or the termination of any Commitment after the making of any Swing Line
Loan; (v) any breach of this Agreement or any other Loan Document by any
Borrower or any Lender; or (vi) any other circumstance, happening or event
whatsoever, whether or not similar to any of the foregoing.

                      SECTION 2.4.  Uncommitted Foreign Currency Revolving
Loans.  Subject to compliance by the Company with the terms of Section 2.1.4,
Section 5.1 and Section 5.2.1, and compliance by the applicable Foreign
Borrower with the terms of Section 5.2.2 (and, in the case of any Foreign
Borrower other than the Initial Foreign Borrowers, compliance by the applicable
Foreign Borrower with the terms of Section 5.3), each Lender severally agrees
that any Foreign Borrower may request that Uncommitted Foreign Currency
Revolving Loan Borrowings be made to it pursuant to this Section 2.4 from time
to time on any Business Day prior to the Revolving Loan Commitment Termination
Date.  No Foreign Borrower may deliver to the Administrative Agent any
Uncommitted Foreign Currency Revolving Loan Borrowing Request in respect of
Uncommitted Foreign Currency Revolving Loans in any Foreign Currency if there
shall exist any unused Revolving Loan Foreign Currency Commitment in respect of
such Foreign Currency unless such Revolving Loan Foreign Currency Commitment is
fully utilized prior to or simultaneously with the Uncommitted Foreign Currency
Revolving Loan Borrowing contemplated by such Foreign Currency Revolving Loan
Borrowing Request.

                      SECTION 2.4.1.  Uncommitted Foreign Currency Revolving
Loan Borrowing Request.  (a)  A Foreign Borrower may request that a Borrowing
of Uncommitted Foreign Currency Revolving Loans be made to it by delivering to
the Administrative Agent an Uncommitted Foreign Currency Revolving Loan
Borrowing Request , which shall be substantially in the form of Exhibit B-3
hereto, and specify:

                             (i)  the Foreign Currency in which each such Loan
                      is requested to be made (provided, that a Canadian
                      Borrower may only request and receive Uncommitted Foreign
                      Currency Revolving Loans denominated in Canadian Dollars,
                      an Australian Borrower may only request and receive
                      Uncommitted Foreign Currency Revolving Loans denominated
                      in Australian Dollars, an Italian Borrower may only
                      request and receive Uncommitted Foreign Currency
                      Revolving Loans denominated in Lire and any other Foreign
                      Borrower may

                      only request and receive Uncommitted Foreign Currency
                      Revolving Loans denominated in the Foreign Currency of
                      the country in which such Foreign Borrower's principal
                      business operations are located);

                             (ii)  the principal amount of the Uncommitted
                      Foreign Currency Revolving Loan Borrowing requested to be
                      made to such Foreign Borrower (which shall be in an

                      being made, which principal amount (x) may be greater

Currency Revolving Loan Borrowing is made, the Administrative Agent shall
notify each Lender having a Percentage of any Revolving Loan Commitment of
greater than zero of (i) the amount of the Uncommitted Foreign Currency
Revolving Loan Borrowing, (ii) the U.S. Dollar Equivalent of the outstanding
principal amount of all Foreign Currency Revolving Loans (in the aggregate and
for each Foreign Borrower) immediately after giving effect to such Borrowing

Borrowing was made.

Lenders that have, immediately prior to the effectiveness of such Revolving
Loan Foreign Currency Commitment Addenda, Percentages in respect of the
Revolving Loan U.S. Dollar Commitment of greater than zero, whereby such

Borrower's principal business operations are located for the account of the

Currency Commitment Amount set forth in the applicable Revolving Loan Foreign
Currency Commitment Addendum;

                      (c)  Each Revolving Loan Foreign Currency Commitment
Addendum shall set forth:

                             (i)  the Foreign Borrowers eligible to make
                      Borrowings of Committed Foreign Currency Revolving Loans
                      (and, if Foreign Currency Letters of Credit are therein
                      contemplated, request the issuance of Foreign Currency
                      Letters of Credit) thereunder;

                             (ii)  the Foreign Currency in which Committed
                      Foreign Currency Revolving Loans are to be made (and, if

                      issued) thereunder;

                             (iii)  the Revolving Loan Foreign Currency
                      Commitment Amount under such Revolving Loan Foreign
                      Currency Commitment Addendum, which shall be stated in

                             (iv)  the Percentage of each Lender party to such
                      Revolving Loan Foreign Currency Commitment Addendum in
                      respect of such Revolving Loan Foreign Currency
                      Commitment Amount; and

                             (v)  if such Revolving Loan Foreign Currency

                             (A)  the Issuer in respect of the Foreign Currency
                             Letters of Credit to be issued thereunder;

                             (B)  the Foreign Currency Letter of Credit
                             Commitment Amount under such Revolving Loan
                             Foreign Currency Commitment Addendum, which shall
                             be stated in U.S. Dollars and shall not exceed the
                             Revolving Loan Foreign Currency Commitment Amount
                             set forth in such Revolving Loan Foreign Currency
                             Commitment Addendum; and

                             (C)  the Letter of Credit Reimbursement Obligation
                             Rate in respect of Foreign Currency Letters of
                             Credit issued thereunder.

                      (d)  Upon the effectiveness of any Revolving Loan Foreign
Currency Commitment Addendum pursuant to clause (a) of Section 2.5 or any
reduction in any Revolving Loan Foreign Currency Commitment pursuant to Section
2.2, the Percentages of each Lender with a Percentage in respect of the
applicable Revolving Loan Foreign Currency Commitments or the Revolving Loan
U.S. Dollar Commitments in excess of zero shall be automatically adjusted so
that, after giving effect to such adjustment, the aggregate amount of the
respective Percentages of each Lender in respect of Revolving Loan Commitments
multiplied by the respective Revolving Loan Commitment Amounts shall, before
and after giving effect to such Revolving Loan Foreign Currency Commitment
Addendum or reduction and such adjustment, be equal.  Schedule III hereto sets
forth an illustration of the operation of this Section 2.5(d).

                      (e)  If and when any adjustment is made to any Percentage
of any Lender pursuant to clause (d) at any time when any Committed Revolving
Loans or Letters of Credit are outstanding, at such time and in such manner as
the Company and the Syndication Agent shall agree (it being understood that the
Company and the Agents will use all commercially reasonable efforts to avoid
prepayment or assignment of any Committed Revolving Loan that is a LIBO Rate
Loan on a day other than the last day of the Interest Period applicable
thereto), the Lender shall assign and assume outstanding Committed Revolving
Loans and participations in outstanding Letters of Credit held by each Lender
to conform to the respective Percentages of the respective Revolving Loan
Commitments of the Lenders.

                      SECTION 2.6.  Continuation and Conversion Elections.  By
delivering a Continuation/Conversion Notice to the Administrative Agent on or
before 12:00 noon, New York City time, on a Business Day, a Borrower may from
time to time





                                       76
<PAGE>   85
irrevocably elect, on not less than one Business Day's notice (in the case of a
conversion of LIBO Rate Loans to Base Rate Loans) or three Business Days'
notice (in the case of a continuation of LIBO Rate Loans or a conversion of
Base Rate Loans into LIBO Rate Loans) nor more than five Business Days' notice
(in the case of any Loans) that all, or any portion in a minimum amount of
$1,000,000 (or, in the case of Foreign Currency Loans, the multiple of 100,000
units of the Currency of such Loans the U.S. Dollar Equivalent of which is
nearest to $1,000,000) or any larger integral multiple of $500,000 (or, in the
case of Foreign Currency Loans, the multiple of 50,000 units of the Currency of
such Loans the U.S. Dollar Equivalent of which is nearest to $500,000) of any
Borrowing of Committed Loans be, in the case of Base Rate Loans, converted into
LIBO Rate Loans or, in the case of LIBO Rate Loans, continued as LIBO Rate
Loans or, in the case of U.S. Dollar Revolving Loans only, converted into Base
Rate Loans (in the absence of delivery of a Continuation/Conversion Notice with
respect to any Committed Loan that is a LIBO Rate Loan at least three Business
Days before the last day of the then current Interest Period with respect
thereto, such LIBO Rate Loan shall (A) in the case of a LIBO Rate Loan that is
a Foreign Currency Loan, automatically be continued as a LIBO Rate Loan with an
Interest Period of one month and (B) in the case of a LIBO Rate Loan that is a
U.S. Dollar Loan, automatically convert to a Base Rate Loan, in each case on
such last day); provided, however, that (x) each such conversion or
continuation shall be pro rated among the applicable outstanding Committed
Loans of the relevant Lenders, (y) no portion of the outstanding principal
amount of any Loans denominated in U.S. Dollars may be continued as, or be
converted into, LIBO Rate Loans when any Default has occurred and is continuing
and (z) Loans shall be continued as, or be converted into, Loans of the same
Currency.

                      SECTION 2.7.  Funding.  Each Lender may, if it so elects,
fulfill its obligation to make, continue or convert LIBO Rate Loans hereunder
by causing one of its foreign branches or Affiliates (or an international
banking facility created by such Lender) to make or maintain such LIBO Rate
Loan, so long as such action does not result in increased costs to the
applicable Borrower; provided, however, that such LIBO Rate Loan shall
nonetheless be deemed to have been made and to be held by such Lender, and the
obligation of the applicable Borrower to repay such LIBO Rate Loan shall
nevertheless be to such Lender for the account of such foreign branch,
Affiliate or international banking facility; and provided, further, however,
that, except for purposes of determining whether any such increased costs are
payable by the applicable Borrower, such Lender shall cause such foreign
branch, Affiliate or international banking facility to comply with the
applicable provisions of clause (b) of Section 4.6 with respect to such LIBO
Rate Loan.  In addition, each Borrower hereby





                                       77
<PAGE>   86
consents and agrees that, for purposes of any determination to be made for
purposes of Section 4.1, 4.2, 4.3 or 4.4, it shall be conclusively assumed that
each Lender elected to fund all LIBO Rate Loans by purchasing deposits in the
relevant Currency in its LIBOR Office's interbank Eurodollar market.

                      SECTION 2.8.  Issuance Procedures.  By delivering to the
applicable Issuer and the Administrative Agent an Issuance Request on or before
12:00 noon, New York time, on a Business Day, any Borrower as to which any
Issuer has a Letter of Credit Commitment may, from time to time irrevocably
request, on not less than three nor more than ten Business Days' notice (or
such shorter or longer notice as may be acceptable to the applicable Issuer),
in the case of an initial issuance of a Letter of Credit, and not less than
three nor more than ten Business Days' notice (unless a shorter or longer
notice period is acceptable to the applicable Issuer) prior to the then
existing Stated Expiry Date of a Letter of Credit, in the case of a request for
the extension of the Stated Expiry Date of a Letter of Credit, that such Issuer
issue, or extend the Stated Expiry Date of, as the case may be, an irrevocable
Letter of Credit on behalf of such Borrower denominated in the applicable
Currency (whether issued for the account of or on behalf of such Borrower or
any of its Subsidiaries) in such form as may be requested by such Borrower and
approved by such Issuer, for the purposes described in Section 7.1.9.
Notwithstanding anything to the contrary contained herein or in any separate
application for any Letter of Credit, each Borrower hereby acknowledges and
agrees that it shall be obligated to reimburse the applicable Issuer upon each
Disbursement paid under a Letter of Credit, and it shall be deemed to be the
obligor for purposes of each such Letter of Credit issued hereunder by such
Issuer at the request of such Borrower (whether the account party on such
Letter of Credit is such Borrower or a Subsidiary of such Borrower).  Upon
receipt of an Issuance Request, the Administrative Agent shall promptly notify
the applicable Issuer and each Lender that has a Percentage of more than zero
in respect of the relevant Revolving Loan Commitments thereof.  Each Letter of
Credit shall by its terms be stated to expire on a date (its "Stated Expiry
Date") no later than the earlier to occur of (i) the sixth anniversary of the
Closing Date or (ii) one year from the date of its issuance; provided, that,
notwithstanding the terms of clause (ii) above, a Letter of Credit may, if
required by the beneficiary thereof, contain "evergreen" provisions pursuant to
which the Stated Expiry Date shall be automatically extended, unless notice to
the contrary shall have been given to the beneficiary by the applicable Issuer
or the account party more than a specified period prior to the then existing
Stated Expiry Date.  The applicable Issuer will make available to the
beneficiary thereof the original of each Letter of Credit which it issues
hereunder.  In the event that the Issuer is other than the Administrative
Agent, such Issuer will send by





                                       78
<PAGE>   87
facsimile transmission to the Administrative Agent, promptly on the first
Business Day of each week, its daily maximum amount available to be drawn under
the Letters of Credit issued by such Issuer for the previous week.  The
Administrative Agent shall deliver to each Lender upon each calendar month end,
and upon each Letter of Credit fee payment, a report setting forth the daily
maximum amount available to be drawn for all Issuers during such period.

                      SECTION 2.8.1.  Other Lenders' Participation.  Upon the
issuance of each Letter of Credit issued by an Issuer pursuant hereto, and
without further action, each Lender (other than such Issuer) that has a
Percentage of more than zero in respect of the relevant Revolving Loan
Commitments shall be deemed to have irrevocably purchased from such Issuer, to
the extent of its Percentage in respect of the applicable Revolving Loan
Commitments and such Issuer shall be deemed to have irrevocably granted and
sold to such Lender a participation interest in such Letter of Credit
(including the Contingent Liability and any Reimbursement Obligation and all
rights with respect thereto), and such Lender shall, to the extent of its
Percentage in respect of the applicable Revolving Loan Commitments be
responsible for reimbursing promptly (and in any event within one Business Day)
the applicable Issuer for Reimbursement Obligations which have not been
reimbursed by the applicable Borrower in accordance with Section 2.8.3.  In
addition, such Lender shall, to the extent of its Percentage in respect of the
applicable Revolving Loan Commitments, be entitled to receive from the
Administrative Agent a ratable portion of the Letter of Credit fees payable
pursuant to Section 3.3.3 with respect to each Letter of Credit and of interest
payable pursuant to Section 3.2 with respect to any Reimbursement Obligation.
To the extent that any Lender has reimbursed an Issuer for a Disbursement as
required by this Section, such Lender shall be entitled to receive from the
Administrative Agent its ratable portion of any amounts subsequently received
(from the applicable Borrower or otherwise) in respect of such Disbursement.

                      SECTION 2.8.2.  Disbursements; Conversion to Committed
Revolving Loans.  Each Issuer will notify the applicable Borrower and the
Administrative Agent promptly of the presentment for payment of any drawing
under any Letter of Credit issued by such Issuer, together with notice of the
date (the "Disbursement Date") such payment shall be made (each such payment, a
"Disbursement").  Subject to the terms and provisions of such Letter of Credit
and this Agreement, such Issuer shall make such payment to the beneficiary (or
its designee) of such Letter of Credit.  Prior to 12:30 p.m., New York time, on
the first Business Day following the Disbursement Date (the "Disbursement Due
Date"), the applicable Borrower will reimburse the





                                       79
<PAGE>   88
Administrative Agent, for the account of such Issuer, for all amounts which
such Issuer has disbursed under such Letter of Credit, together with interest
thereon at the rate per annum otherwise applicable to U.S. Dollar Revolving
Loans made as Base Rate Loans (in the case of U.S. Dollar Letters of Credit) or
at the Letter of Credit Reimbursement Obligation Rate in respect of such Letter
of Credit (in the case of any other Letter of Credit) from and including the
Disbursement Date to but excluding the Disbursement Due Date and, thereafter
(unless such Disbursement is converted into a Committed Revolving Loan on the
Disbursement Due Date), at a rate per annum equal to the rate per annum then in
effect with respect to overdue U.S. Dollar Revolving Loans made as Base Rate
Loans pursuant to Section 3.2.2 (in the case of U.S.  Dollar Letters of Credit)
or at a rate per annum equal to the Letter of Credit Reimbursement Obligation
Rate in respect of such Letter of Credit plus 2% (in the case of any other
Letter of Credit) for the period from the Disbursement Due Date through the
date of such reimbursement; provided, however, that, if no Default shall have
then occurred and be continuing, unless the applicable Borrower has notified
the Administrative Agent no later than one Business Day prior to the
Disbursement Due Date that it will reimburse such Issuer for the applicable
Disbursement, then the amount of the Disbursement shall be deemed to be a
Borrowing of Committed Revolving Loans in the applicable Currency which, in the
case of U.S. Dollars, shall constitute Base Rate Loans  and, in the case of any
Foreign Currency, shall bear interest at the Letter of Credit Reimbursement
Obligation Rate set forth in the applicable Revolving Loan Foreign Currency
Commitment Addendum, and following the giving of notice thereof by the
Administrative Agent to the applicable Lenders, each Lender with a Percentage
of greater than zero in respect of the applicable Revolving Loan Commitments
(other than such Issuer) will deliver to such Issuer on the Disbursement Due
Date immediately available funds in the applicable Currency in an amount equal
to such Lender's applicable Percentage of such Borrowing.  Each conversion of
Disbursement amounts into Committed Revolving Loans shall constitute a
representation and warranty by the applicable Borrower that on the date of the
making of such Committed Revolving Loans all of the statements set forth in
Section 5.2.1 are true and correct.

                      SECTION 2.8.3.  Reimbursement.  The obligation (a
"Reimbursement Obligation") of a Borrower under Section 2.8.2 to reimburse an
Issuer with respect to each Disbursement (including interest thereon) not
converted into a Committed Revolving Loan pursuant to Section 2.8.2, and, upon
the failure of any Borrower to reimburse an Issuer and the giving of notice
thereof by the Administrative Agent to the applicable Lenders, each Lender's
(to the extent it has a Percentage of greater than zero in respect of the
applicable Revolving Loan Commitment Amount)





                                       80
<PAGE>   89
obligation under Section 2.8.1 to reimburse such Issuer or fund its Percentage
of any Disbursement converted into a Committed Revolving Loan, shall be
absolute and unconditional under any and all circumstances and irrespective of
any setoff, counterclaim or defense to payment which such Borrower or such
Lender, as the case may be, may have or have had against such Issuer or any
such Lender, including any defense based upon the failure of any Disbursement
to conform to the terms of the applicable Letter of Credit (if, in the
applicable Issuer's good faith opinion, such Disbursement is determined to be
appropriate) or any non-application or misapplication by the beneficiary of the
proceeds of such Letter of Credit; provided, however, that after paying in full
its Reimbursement Obligation hereunder, nothing herein shall adversely affect
the right of such Borrower or such Lender, as the case may be, to commence any
proceeding against the applicable Issuer for any wrongful Disbursement made by
such Issuer under a Letter of Credit as a result of acts or omissions
constituting gross negligence or willful misconduct on the part of such Issuer.

                      SECTION 2.8.4.  Deemed Disbursements.  Upon the
occurrence and during the continuation of any Event of Default of the type
described in clauses (b) through (d) of Section 8.1.9 with respect to any
Obligor (other than Immaterial Subsidiaries) or, with notice from the
Administrative Agent acting at the direction of the Required Lenders, upon the
occurrence and during the continuation of any other Event of Default,

                             (a)  an amount equal to that portion of all Letter
                      of Credit Outstandings attributable to the then aggregate
                      amount which is undrawn and available under all Letters
                      of Credit issued at the request of any Borrower and
                      outstanding shall, without demand upon or notice to such
                      Borrower or any other Person, be deemed to have been paid
                      or disbursed by the applicable Issuer under such Letters
                      of Credit (notwithstanding that such amount may not in
                      fact have been so paid or disbursed); and

                             (b)  upon notification by the Administrative Agent
                      to the applicable Borrower of its obligations under this
                      Section, such Borrower shall be immediately obligated to
                      reimburse the applicable Issuer for the amount deemed to
                      have been so paid or disbursed by the applicable Issuer.

Any amounts so payable by any Borrower pursuant to this Section shall be
deposited in cash in the applicable Currency with the Administrative Agent and
held as collateral security for the Obligations in connection with the Letters
of Credit issued





                                       81
<PAGE>   90
at the request of such Borrower by the applicable Issuer.  At such time as the
Events of Default giving rise to the deemed disbursements hereunder shall have
been cured or waived, the Administrative Agent shall return to the applicable
Borrower all amounts then on deposit with the Administrative Agent pursuant to
this Section, together with accrued interest at the Federal Funds Rate, which
have not been applied to the satisfaction of such Obligations.

                      SECTION 2.8.5.  Nature of Reimbursement Obligations.
Each Borrower and, to the extent set forth in Section 2.8.1, each Lender with
an applicable Revolving Loan Commitment, shall assume all risks of the acts,
omissions or misuse of any Letter of Credit by the beneficiary thereof.  No
Issuer (except to the extent of its own gross negligence or willful misconduct)
shall be responsible for:

                             (a)  the form, validity, sufficiency, accuracy,
                      genuineness or legal effect of any Letter of Credit or
                      any document submitted by any party in connection with
                      the application for and issuance of a Letter of Credit,
                      even if it should in fact prove to be in any or all
                      respects invalid, insufficient, inaccurate, fraudulent or
                      forged;

                             (b)  the form, validity, sufficiency, accuracy,
                      genuineness or legal effect of any instrument
                      transferring or assigning or purporting to transfer or
                      assign a Letter of Credit or the rights or benefits
                      thereunder or the proceeds thereof in whole or in part,
                      which may prove to be invalid or ineffective for any
                      reason;

                             (c)  failure of the beneficiary to comply fully
                      with conditions required in order to demand payment under
                      a Letter of Credit;

                             (d)  errors, omissions, interruptions or delays in
                      transmission or delivery of any messages, by mail, cable,
                      telegraph, telex or otherwise; or

                             (e)  any loss or delay in the transmission or
                      otherwise of any document or draft required in order to
                      make a Disbursement under a Letter of Credit.

None of the foregoing shall affect, impair or prevent the vesting of any of the
rights or powers granted to any Issuer or any Lender with an applicable
Revolving Loan Commitment hereunder.  In furtherance and extension and not in
limitation or derogation of any of the foregoing, any action taken or omitted
to be taken by any Issuer in good faith (and not constituting gross negligence
or willful misconduct) shall





                                       82
<PAGE>   91
be binding upon the applicable Borrower, each Obligor and each such Lender, and
shall not put such Issuer under any resulting liability to such Borrower, any
Obligor or any such Lender, as the case may be.

                      SECTION 2.9.  Register; Notes.  (a)  Each Lender may
maintain in accordance with its usual practice an account or accounts
evidencing the Indebtedness of each Borrower to such Lender resulting from each
Loan made by such Lender to such Borrower, including the amounts of principal
and interest payable and paid to such Lender from time to time hereunder.  In
the case of a Lender that does not request, pursuant to clause (b)(ii) below,
execution and delivery of a Note or Notes evidencing the Loans made by such
Lender to a Borrower, such account or accounts shall, to the extent not
inconsistent with the notations made by the Administrative Agent in the
Register, be conclusive and binding on such Borrower absent manifest error;
provided, however, that the failure of any Lender to maintain such account or
accounts shall not limit or otherwise affect any Obligations of any Borrower or
any other Obligor.

                             (b) (i)  Each Borrower hereby designates the
                      Administrative Agent to serve as its agent, solely for
                      the purpose of this clause (b), to maintain a register
                      (the "Register") on which the Administrative Agent will
                      record each Lender's Commitments, the Loans made by each
                      Lender to each Borrower and each repayment in respect of
                      the principal amount of the Loans of each Lender to each
                      Borrower and annexed to which the Administrative Agent
                      shall retain a copy of each Revolving Loan Foreign
                      Currency Commitment Addendum delivered to the
                      Administrative Agent pursuant to Section 2.5 and each
                      Lender Assignment Agreement delivered to the
                      Administrative Agent pursuant to Section 11.11.1.
                      Failure to make any recordation, or any error in such
                      recordation, shall not affect the Borrowers' obligations
                      in respect of such Loans.  The entries in the Register
                      shall be conclusive, in the absence of manifest error,
                      and the Borrowers, the Administrative Agent and the
                      Lenders shall treat each Person in whose name a Loan
                      (and, as provided in clause (ii), the Note evidencing
                      such Loan, if any) is registered as the owner thereof for
                      all purposes of this Agreement, notwithstanding notice or
                      any provision herein to the contrary.  Any Commitment of
                      any Lender and the Loans made pursuant thereto may be
                      assigned or otherwise transferred in whole or in part
                      only by registration of such assignment or transfer in
                      the Register.  Any assignment or transfer of any
                      Commitment of any Lender or the Loans made pursuant
                      thereto shall be registered in the Register only upon
                      delivery to the Administrative Agent of a Lender
                      Assignment Agreement duly executed by the





                                       83
<PAGE>   92
                      assignor thereof.  No assignment or transfer of any
                      Commitment of any Lender or the Loans made pursuant
                      thereto shall be effective unless such assignment or
                      transfer shall have been recorded in the Register by the
                      Administrative Agent as provided in this Section.

                             (ii)  Each Borrower agrees that, upon the request
                      by any Lender to the Administrative Agent, such Borrower
                      will execute and deliver to such Lender, as applicable, a
                      Revolving U.S. Dollar Note, a Revolving Australian
                      Dollar Note, a Revolving Canadian Dollar Note, a
                      Revolving Lira Note, a Term-A U.S. Dollar Note, a Term-A
                      Australian Dollar Note, a Term-A Lira Note, a Term-B
                      Note, a Term-C Note, any other applicable Revolving
                      Foreign Currency Note and a Swing Line Note evidencing
                      the Loans made by such Lender to such Borrower.  Each
                      Borrower hereby irrevocably authorizes each Lender to
                      make (or cause to be made) appropriate notations on the
                      grid attached to such Lender's Notes of such Borrower (or
                      on any continuation of such grid), which notations, if
                      made, shall evidence, inter alia, the date of, the
                      outstanding principal amount of, and the interest rate
                      and Interest Period applicable to the Loans evidenced
                      thereby.  Such notations shall, to the extent not
                      inconsistent with the notations made by the
                      Administrative Agent in the Register, be conclusive and
                      binding on the Borrower that shall have issued such Note
                      absent manifest error; provided, however, that the
                      failure of any Lender to make any such notations or any
                      error in any such notations shall not limit or otherwise
                      affect any Obligations of the Borrowers or any other
                      Obligor.  The Loans evidenced by any such Note and
                      interest thereon shall at all times (including after
                      assignment pursuant to Section 11.11.1) be represented by
                      one or more Notes payable to the order of the payee named
                      therein and its registered assigns.  A Note and the
                      obligation evidenced thereby may be assigned or otherwise
                      transferred in whole or in part only by registration of
                      such assignment or transfer of such Note and the
                      obligation evidenced thereby in the Register (and each
                      Note shall expressly so provide).  Any assignment or
                      transfer of all or part of an obligation evidenced by a
                      Note shall be registered in the Register only upon
                      surrender for registration of assignment or transfer of
                      the Note evidencing such obligation, accompanied by a
                      Lender Assignment Agreement duly executed by the assignor
                      thereof, and thereupon, if requested by the assignee, one
                      or more new Notes shall be issued by the applicable
                      Borrower to the designated assignee and the old Note
                      shall be returned by the Administrative Agent to the
                      applicable Borrower marked "exchanged".  No assignment of
                      a Note and the obligation evidenced thereby





                                       84
<PAGE>   93
                      shall be effective unless it shall have been recorded in
                      the Register by the Administrative Agent as provided in
                      this Section.

                                  ARTICLE III

                   REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

                      SECTION 3.1.  Repayments and Prepayments; Application.

                      SECTION 3.1.1.  Repayments and Prepayments.  Each
Borrower shall repay in full the unpaid principal amount of each Loan made to
it upon the Stated Maturity Date therefor.  Prior thereto, payments and
repayments of Loans shall or may be made as set forth below.

                             (a) From time to time on any Business Day, the
                      Company or a Foreign Borrower, as the case may be, may
                      make a voluntary prepayment, in whole or in part, of the
                      outstanding principal amount of any

                                  (i)  Loans (other than Swing Line Loans);
                             provided, however, that

                                        (1) any such prepayment of the Loans of
                                  any Tranche shall be made pro rata among
                                  Loans of such Tranche of the same type and,
                                  if applicable, having the same Interest
                                  Period of all Lenders that have made such
                                  Loans;

                                        (2)  each Borrower shall comply with

                      Revolving Loans and Swing Line Loans, to the extent then
                      outstanding, as the Company shall elect, and, second,

                      Letter of Credit Outstandings, in an aggregate amount

                      had been outstanding.

                      to Section 8.2 or Section 8.3, the Company or any

<PAGE>   100
                      applicable Foreign Borrower, as the case may be, shall
                      repay all outstanding Loans and other Obligations,
                      unless, pursuant to Section 8.3, only a portion of all
                      Loans and other Obligations are so accelerated (in which
                      case the portion so accelerated shall be so prepaid).

                      Each prepayment of any Loans made pursuant to this
Section shall be without premium or penalty, except as may be required by
Section 4.4.  No prepayment of principal of any Revolving Loans or Swing Line
Loans pursuant to clause (a), (b) or (m) of this Section 3.1.1 shall cause a
reduction in any Revolving Loan Commitment Amount or the Swing Line Loan
Commitment Amount, as the case may be.  Any Letter of Credit outstanding that
is cash collateralized pursuant to clause (b), (g), (h) or (l) of this Section
3.1.1 shall not thereafter, so long as, and to the extent that, such Letter of
Credit remains so cash collateralized, be considered to be outstanding for
purposes of (but only for purposes of) such clause (b), (g), (h) or (l) of
this Section 3.1.1.

                      SECTION 3.1.2.  Application.  (a) Subject to clause (b)
below, each prepayment or repayment of principal of the Loans of any Tranche
shall be applied, to the extent of such prepayment or repayment, first, to the
principal amount thereof being maintained as Base Rate Loans, and second, to
the principal amount thereof being maintained as LIBO Rate Loans; provided,
that prepayments or repayments of LIBO Rate Loans not made on the last day of
the Interest Period with respect thereto, shall be prepaid or repaid subject to
the provisions of Section 4.4 (together with a payment of all accrued
interest).  Any mandatory prepayments of LIBO Rate Loans made pursuant to
clauses (d) and (e) of Section 3.1.1, if not made on the last day of the
Interest Period with respect thereto, shall, at the Borrower's option, so long
as no Default has occurred and is continuing, be prepaid subject to the
provisions of Section 4.4, or the amount required to be applied to the
prepayment of LIBO Rate Loans (after application to any Base Rate Loans) shall
be deposited with the Administrative Agent as cash collateral for such Loans on
terms reasonably satisfactory to the Administrative Agent and thereafter shall
be applied in the order of the Interest Periods next ending most closely to the
date of receipt of the proceeds in respect of which such prepayment is required
to be made and on the last day of each such Interest Period (together with a
payment of all interest that is due on the last day of each such Interest
Period pursuant to clause (d) of Section 3.2.3).

                      (b)  Each prepayment of Term Loans made pursuant to
clauses (a), (c), (d), (e), (f), (i), (j) and (k) of Section 3.1.1 shall be
applied, (i) on a pro rata basis, to the outstanding principal amount of (A) in
the case of clauses (a), (c), (d), (e) and (f), all remaining Term-A Loans,
Term-B Loans and Term-C Loans and (B) in the case of clauses (i), (j) and (k),
all remaining Term-A Loans, Term-B Loans or Term-C Loans, as the case may be,
and (ii) in





                                       92
<PAGE>   101
respect of each Tranche of Term Loans, in direct order of maturity of the
remaining scheduled quarterly amortization payments in respect thereof, until
all such Term-A Loans, Term-B Loans and Term-C Loans have been paid in full;
provided that the Company may make, or cause other Borrowers to make, any such
prepayments to any Lender of Term Loans of such Tranches as the Company shall
elect so long as the aggregate amount of all such prepayments made to each
Lender is equal to its pro rata portion of the aggregate prepayments to all
applicable Lenders; and provided, further, that if the Company at any time
elects in writing, in its sole discretion, to permit any Lender that has Term-B
Loans or Term-C Loans to decline to have such Loans prepaid pursuant to clause
(a), (c), (d), (e) or (f) of Section 3.1.1, then any Lender having Term-B Loans
or Term-C Loans outstanding may, by delivering a notice to the Agents at least
one Business Day prior to the date that such prepayment is to be made, decline
to have such Loans prepaid with the amounts set forth above, in which case 50%
of the amounts that would have been applied to a prepayment of such Lender's
Term-B Loans or Term-C Loans, as the case may be, shall instead be applied to a
prepayment of the Term-A Loans (until paid in full), with the balance being
retained by the Company and its Subsidiaries.

                      SECTION 3.2.  Interest Provisions.  Interest on the
outstanding principal amount of the Loans shall accrue and be payable in
accordance with this Section 3.2.

                      SECTION 3.2.1.  Rates.  (a)  Each Base Rate Loan shall
accrue interest on the unpaid principal amount thereof for each day from and
including the day upon which such Loan was made or converted to a Base Rate
Loan to but excluding the date such Loan is repaid or converted to a LIBO Rate
Loan at a rate per annum equal to the sum of the Alternate Base Rate for such
day plus the Applicable Margin for such Loan on such day.

                      (b)  Each Committed LIBO Rate Loan in any Currency shall
accrue interest on the unpaid principal amount thereof for each day during each
Interest Period applicable thereto at a rate per annum equal to the sum of the
LIBO Rate (or, in the case of U.S. Dollar Loans, LIBO Rate (Reserve Adjusted))
for such Currency and Interest Period plus the Applicable Margin for such Loan
on such day.

                      (c)  Each Uncommitted Foreign Currency Revolving Loan
shall accrue interest on the unpaid principal amount thereof for each day from
and including the day upon which such Loan was made to but excluding the date
such Loan is repaid at a rate per annum equal to the Uncommitted Foreign
Currency Interest Rate for such Loan.





                                       93
<PAGE>   102
All LIBO Rate Loans shall bear interest from and including the first day of the
applicable Interest Period to (but not including) the last day of such Interest
Period at the interest rate determined as applicable to such LIBO Rate Loan.

                      SECTION 3.2.2.  Post-Maturity Rates.  After the date any
principal amount of any Loan shall have become due and payable (whether on the
applicable Stated Maturity Date, upon acceleration or otherwise), or any other
monetary Obligation (other than overdue Reimbursement Obligations which shall
bear interest as provided in Section 2.8.2) of any Borrower shall have become
due and payable, such Borrower shall pay, but only to the extent permitted by
law, interest (after as well as before judgment) on such amounts at a rate per
annum equal to (i) in the case of any overdue principal of Loans, overdue
interest thereon, overdue commitment fees or other overdue amounts in respect
of Loans or other obligations (or the related Commitments) under a particular
Tranche, (x) in the case of Loans other than Foreign Currency Loans, the rate
that would otherwise be applicable to Base Rate Loans under such Tranche
pursuant to Section 3.2.1 plus 2%, (y) in the case of Committed Foreign
Currency Loans, the rate that would otherwise be applicable to such Loans under
clause (b) of Section 3.2.1 plus 2%, and (z) in the case of Uncommitted Foreign
Currency Revolving Loans, the rate that would otherwise be applicable to such
Loans pursuant to clause (c) of Section 3.2.1 plus 2%, and (ii) in the case of
other overdue monetary Obligations, the rate that would otherwise be applicable
to U.S. Dollar Revolving Loans that were Base Rate Loans plus 2%.

                      SECTION 3.2.3.  Payment Dates.  Interest accrued on each
Loan shall be payable, without duplication:

                             (a)  on the Stated Maturity Date therefor;

                             (b)  in the case of a LIBO Rate Loan or
                      Uncommitted Foreign Currency Absolute Rate Revolving
                      Loan, on the date of any payment or prepayment, in whole
                      or in part, of principal outstanding on such Loan, to the
                      extent of the unpaid interest accrued through such date
                      on the principal so paid or prepaid;

                             (c)  with respect to Base Rate Loans, on each
                      Quarterly Payment Date occurring after the date of the
                      initial Credit Extension hereunder;

                             (d)  with respect to LIBO Rate Loans, on the last
                      day of each applicable Interest Period (and, if such
                      Interest Period shall exceed three months, at intervals
                      of three months after the first day of such Interest
                      Period); and





                                       94
<PAGE>   103
                             (e)  on that portion of any Loans the Stated
                      Maturity Date of which is accelerated pursuant to Section
                      8.2 or Section 8.3, immediately upon such acceleration.

Interest accrued on Loans, Reimbursement Obligations or other monetary
Obligations arising under this Agreement or any other Loan Document after the
date such amount is due and payable (whether on the Stated Maturity Date, upon
acceleration or otherwise) shall be payable upon demand.

                      SECTION 3.3.  Fees.  The Borrowers agree to pay the fees
set forth in this Section 3.3.  All such fees shall be non-refundable.

                      SECTION 3.3.1.  Commitment Fee.  Each Borrower agrees to
pay to the Administrative Agent for the account of each Lender that has a
Revolving Loan Commitment to such Borrower for each day during the period
(including any portion thereof when any of the Lenders' applicable Revolving
Loan Commitments are suspended by reason of the Company's inability to satisfy
any condition of Article V) commencing on the Closing Date and continuing to
but excluding the Revolving Loan Commitment Termination Date, a commitment fee
on such Lender's Percentage of the unused portion, whether or not then
available to the applicable Borrower, of the Revolving Loan Commitment Amount
with respect to such Revolving Loan Commitment (net of Letter of Credit
Outstandings in respect of Letters of Credit outstanding under the related
Letter of Credit Commitment) for such day at a rate per annum equal to the
Applicable Commitment Fee for such day.  Such commitment fees shall be payable
by the applicable Borrower in arrears on each Quarterly Payment Date,
commencing with the first such day following the Closing Date and on the
Revolving Loan Commitment Termination Date.  The making of Swing Line Loans and
Uncommitted Foreign Currency Revolving Loans shall not constitute usage of the
applicable Revolving Loan Commitment with respect to the calculation of
commitment fees to be paid by the Borrowers to the applicable Lenders.  Any
term or provision hereof to the contrary notwithstanding, commitment fees
payable for any period prior to the Closing Date shall be payable in accordance
with the Fee Letter.  Payments by the Company to the Swing Line Lender in
respect of accrued interest on Swing Line Loans shall be net of the commitment
fee payable in respect of the Swing Line Lender's Revolving Loan Commitment.

                      SECTION 3.3.2.  Administrative Agent Fee.  The Company
agrees to pay an annual administration fee to the Administrative Agent, for its
own account, in the amount set forth in the Administrative Agent Fee Letter,
payable in advance on the Closing Date and annually thereafter.





                                       95
<PAGE>   104
                      SECTION 3.3.3.  Letter of Credit Fee.  Each Borrower
agrees to pay to the Administrative Agent, for the pro rata account of the
applicable Issuer and each other Lender that has a Percentage of greater than
zero in respect of the applicable Revolving Loan Commitment Amount, a Letter of
Credit fee for each day on which there shall be any Letters of Credit
outstanding under any Letter of Credit Commitment to such Borrower, at a rate
per annum equal to (i) with respect to each standby Letter of Credit, the then
Applicable Margin for Revolving Loans maintained as LIBO Rate Loans, minus 1/8
of 1% per annum, multiplied by the Stated Amount of each such Letter of Credit;
and (ii) with respect to each documentary Letter of Credit, 1.25% multiplied by
the Stated Amount of each such Letter of Credit, such fees being payable in the
Currency in which such Letter of Credit is denominated quarterly in arrears on
each Quarterly Payment Date.  Each Borrower further agrees to pay to the
applicable Issuer quarterly in arrears on each Quarterly Payment Date, an
issuance fee equal to 1/8 of 1% per annum, multiplied by the Stated Amount of
the applicable Letter of Credit.


                                   ARTICLE IV

                     CERTAIN LIBO RATE AND OTHER PROVISIONS

                      SECTION 4.1.  LIBO Rate Lending Unlawful.  If any Lender
shall determine (which determination shall, in the absence of manifest error,
upon notice thereof to the Company and the Lenders, be conclusive and binding
on the Borrowers) that the introduction of or any change in or in the
interpretation of any law, in each case after (i) in the case of any such
introduction or change with respect to Committed Loans, the date upon which
such Lender shall have become a Lender hereunder, and (ii) in the case of any
such introduction or change with respect to Uncommitted Foreign Currency
Revolving Loans, the date on which such Lender submitted an Uncommitted Foreign
Currency Interest Quote in respect of such Uncommitted Foreign Currency
Revolving Loan pursuant to Section 2.4 makes it unlawful, or any central bank
or other governmental authority asserts, after such date, that it is unlawful,
for such Lender to make, continue or maintain any Loan as, or to convert any
Loan into, a LIBO Rate Loan, the obligations of such Lender to make, continue,
maintain or convert any Loans as or to LIBO Rate Loans shall, upon such
determination, forthwith be suspended until such Lender shall notify the
Administrative Agent that the circumstances causing such suspension no longer
exist, which such Lender shall do promptly upon obtaining actual knowledge of
such change in circumstances (provided that the rights and benefits of such
Lender under this clause relating to any period prior to such failure to give
prompt notice shall not be limited or otherwise adversely affected as a result
of such failure) (with the date of such notice being the "Reinstatement
Date"), and (i) all LIBO Rate Loans





                                       96

previously made by such Lender shall (A) in the case of U.S. Dollar Loans,
automatically convert into Base Rate Loans and (B) in the case of Foreign
Currency Loans, accrue interest at each applicable Lender's cost of funds, as
reasonably determined and as notified by such Lender to the Administrative
Agent and the Company, plus the Applicable Margin in respect of such Foreign
Currency Loans, in each case at the end of the then current Interest Periods
with respect thereto or sooner, if required by such law or assertion, and (ii)
all Loans thereafter to be made by such Lender and outstanding prior to the
Reinstatement Date shall (A) in the case of U.S. Dollar Loans, be made as Base
Rate Loans, with interest thereon being payable on the same date that interest
is payable with respect to the corresponding Borrowing of LIBO Rate Loans made
by Lenders not so affected, and (B) in the case of Foreign Currency Loans,
accrue interest at each applicable Lender's cost of funds, as reasonably
determined and as notified by such Lender to the Administrative Agent and the
Company, plus the Applicable Margin in respect of such Foreign Currency Loans.

                      SECTION 4.2.  Deposits Unavailable.  If the
Administrative Agent shall have determined that

                             (a)  deposits in the relevant Currency and amount
                      and for the relevant Interest Period are not available to
                      the Administrative Agent in its relevant market; or

                             (b)  by reason of circumstances affecting the
                      Administrative Agent's relevant market, adequate means do
                      not exist for ascertaining the interest rate applicable
                      hereunder to LIBO Rate Loans in a particular Currency,

then, upon notice from the Administrative Agent to the Company and the Lenders,
(i) the obligations of all Lenders under Section 2.3 and Section 2.4 to make or
continue any Loans as, or to convert any Loans into, LIBO Rate Loans shall
forthwith be suspended and (ii) in the case of Foreign Currency Loans, such
Loans shall accrue interest at each applicable Lender's cost of funds, as
reasonably determined and as notified by such Lender to the Administrative
Agent and the Company, plus the Applicable Margin in respect of such Loans, at
the end of the then current Interest Period applicable thereto, in each case
until the Administrative Agent shall notify the Company and the Lenders that
the circumstances causing such suspension no longer exist, which the
Administrative Agent shall do promptly upon obtaining actual knowledge of such
change in circumstances (provided that the rights and benefits of the
Administrative Agent under this clause relating to any period prior to such
failure to give prompt notice shall not be limited or otherwise adversely
affected as a result of such failure), and subsequent Foreign Currency Loans in
respect of such Currency shall be made at an interest rate equal to each
applicable Lender's cost of funds, as





                                       97
<PAGE>   106
reasonably determined and as notified by such Lender to the Administrative
Agent and the Company, plus the Applicable Margin in respect of such Loans.

                      SECTION 4.3.  Increased LIBO Rate Loan Costs, etc.  The
applicable Borrower agrees to reimburse each Lender for any increase in the
cost to such Lender of, or any reduction in the amount of any sum receivable by
such Lender in respect of, making, continuing or maintaining (or of its
obligation to make, continue or maintain) any Loans as, or of converting (or of
its obligation to convert) any Loans into, LIBO Rate Loans (excluding any
amounts, whether or not constituting Taxes, referred to in Section 4.6) arising
as a result of any change in, or the introduction, adoption, effectiveness,
interpretation, reinterpretation or phase-in of, any law or regulation,
directive, guideline, decision or request (whether or not having the force of
law) of any court, central bank, regulator or other governmental authority that
occurs after (i) in the case of any such increased costs or reduced return in
respect of Committed Loans, the date upon which such Lender became a Lender
hereunder, and (ii) in the case of any such increased costs or reduced return
in respect of Uncommitted Foreign Currency Revolving Loans, the date on which
such Lender submitted an Uncommitted Foreign Currency Interest Quote with
respect to such Uncommitted Foreign Currency Revolving Loans pursuant to
Section 2.4.  Such Lender shall promptly notify the Administrative Agent and
the Company in writing of the occurrence of any such event, such notice to
state, in reasonable detail, the reasons therefor and the additional amount
required fully to compensate such Lender for such increased cost or reduced
amount.  Such additional amounts shall be payable by the applicable Borrower
directly to such Lender within five days of its receipt of such notice, and
such notice shall, in the absence of manifest error, be conclusive and binding
on the Borrowers.

                      SECTION 4.4.  Funding Losses.  In the event any Lender
shall incur any loss or expense (including any loss or expense incurred by
reason of the liquidation or reemployment of deposits or other funds acquired
by such Lender to make, continue or maintain any portion of the principal
amount of any Loan as, or to convert any portion of the principal amount of any
Loan into, a LIBO Rate Loan, but excluding any loss of margin after the date of
any such conversion, repayment, prepayment or failure to borrow, continue or
convert) as a result of

                             (a)  any conversion or repayment or prepayment of
                      the principal amount of any LIBO Rate Loans on a date
                      other than the scheduled last day of the Interest Period
                      applicable thereto, whether pursuant to Section 3.1 or
                      otherwise;

                             (b)  any Loans not being borrowed as LIBO Rate
                      Loans in accordance with the Borrowing Request therefor;
                      or





                                       98
<PAGE>   107
                             (c)  any Loans not being continued as, or
                      converted into, LIBO Rate Loans in accordance with the
                      Continuation/Conversion Notice therefor,

then, upon the written notice of such Lender to the applicable Borrower (with a
copy to the Administrative Agent), such Borrower shall, within five days of its
receipt thereof, pay directly to such Lender such amount as will (in the
reasonable determination of such Lender) reimburse such Lender for such loss or
expense.  Such written notice (which shall include calculations in reasonable
detail) shall, in the absence of manifest error, be conclusive and binding on
such Borrower.

                      SECTION 4.5.  Increased Capital Costs.  If any change in,
or the introduction, adoption, effectiveness, interpretation, reinterpretation
or phase-in of, any law or regulation, directive, guideline, decision or
request (whether or not having the force of law) of any court, central bank,
regulator or other governmental authority, in each case occurring after (i) in
the case of any such change, introduction, adoption, effectiveness,
interpretation, reinterpretation or phase-in in respect of Committed Loans, the
applicable Lender becomes a Lender hereunder, and (ii) in the case of any such
change, introduction, adoption, effectiveness, interpretation, reinterpretation
or phase-in in respect of Uncommitted Foreign Currency Revolving Loans, the
date on which such Lender submitted an Uncommitted Foreign Currency Interest
Quote in respect of such Uncommitted Foreign Currency Revolving Loan pursuant
to Section 2.4, affects or would affect the amount of capital required or
expected to be maintained by any Lender or any Person controlling such Lender,
and such Lender determines (in its sole and absolute discretion) that the rate
of return on its or such controlling Person's capital as a consequence of its
Commitments, participation in Letters of Credit or the Loans made by such
Lender is reduced to a level below that which such Lender or such controlling
Person could have achieved but for the occurrence of any such circumstance,
then, in any such case upon notice from time to time by such Lender to the
Company, which such Lender shall give promptly upon its obtaining actual
knowledge of such circumstance (provided that the rights and benefits of such
Lender under this clause relating to any period prior to such failure to give
prompt notice shall not be limited or otherwise adversely affected as a result
of such failure), the applicable Borrower shall immediately pay directly to
such Lender additional amounts sufficient to compensate such Lender or such
controlling Person for such reduction in rate of return.  A statement of such
Lender as to any such additional amount or amounts (including calculations
thereof in reasonable detail) shall, in the absence of manifest error, be
conclusive and binding on the Borrowers.  In determining such amount, such
Lender may use any method of averaging and attribution that it (in its sole and
absolute discretion) shall deem applicable; provided, that such Lender may not
impose materially greater costs on the Borrowers than on other similarly
situated borrowers by virtue of any such averaging or attribution method.

<PAGE>   108
                      SECTION 4.6.  Taxes.  (a) All payments by the Borrowers
of principal of, and interest on, the Loans and all other amounts payable
hereunder or under any other Loan Document (including Reimbursement
Obligations, fees and expenses) shall be made free and clear of and without
deduction for any present or future income, excise, stamp or franchise taxes
and other taxes, fees, duties, withholdings or other charges of any nature
whatsoever imposed by any taxing authority, from or through which payments
originate or are made or deemed made by or to the Borrowers, but excluding (i)
any income, excise, stamp or franchise taxes and other similar taxes, fees,
duties, withholdings or other charges imposed on either of the Agents as a
result of a present or former connection between the applicable lending office
(or office through which it performs any of its actions as Agent) of such
Agent, and any income, excise, stamp or franchise taxes and other similar
taxes, fees, duties, withholdings or other charges imposed on any Lender as a
result of a present or former connection between the applicable lending office
of such Lender, in each case and the jurisdiction of the governmental authority
imposing such tax or any political subdivision or taxing authority thereof or
therein (other than any such connection arising solely from such Agent or such
Lender having executed, delivered or performed its obligations or received a
payment under, or taken any action to enforce, this Agreement or any Note) or
(ii) any income, excise, stamp or franchise taxes and other similar taxes,
fees, duties, withholdings or other charges to the extent that they are in
effect and would apply (x) as of the date any Person becomes a Lender or
Assignee Lender to the extent such taxes, fees, duties, withholdings or charges
relate to payments other than payments in respect of Uncommitted Foreign
Currency Revolving Loans, (y) as of the date on which such Lender submitted an
Uncommitted Foreign Currency Interest Quote with respect to such Uncommitted
Foreign Currency Revolving Loans pursuant to Section 2.4, to the extent such
taxes, fees, duties, withholdings or other charges relate to payments in
respect of Uncommitted Foreign Currency Revolving Loans, or (z) in either case,
as of the date that any Lender changes its applicable lending office, to the
extent such taxes become applicable as a result of such change (other than a
change in an applicable lending office made pursuant to Section 4.10 below)
(such non-excluded items being called "Taxes").  In the event that any
withholding or deduction from any payment to be made by any Borrower hereunder
is required in respect of any Taxes pursuant to any applicable law, rule or
regulation, then such Borrower will (i)  pay directly to the relevant taxing
authority the full amount required to be so withheld or deducted, (ii) promptly
forward to the Administrative Agent an official receipt or other documentation
available to such Borrower reasonably satisfactory to the Administrative Agent
evidencing such payment to such authority, and (iii)  pay to the Administrative
Agent for the account of the applicable Lenders such additional amount or
amounts as is necessary to ensure that the net amount actually received by each
such Lender will equal the full amount such applicable Lender would have
received had no such withholding or deduction been required, provided, however,
that the Company shall not be required to pay any such





                                      100
<PAGE>   109
additional amounts in respect of amounts payable to any Non-U.S. Lender or any
Agent that is not organized under the laws of the United States or a state
thereof to the extent that the related tax is imposed (or an exemption
therefrom is not available) as a result of such Lender or Agent failing to
comply with the requirements of clause (b) of Section 4.6.

                      Moreover, if any Taxes are directly asserted against
either of the Agents or any Lender with respect to any payment received by such
Agents or such Lender hereunder, such Agents or such Lender may pay such Taxes
and the applicable Borrower will promptly pay to such Person such additional
amount (including any penalties, interest or expenses) as is necessary in order
that the net amount received by such Person (including any Taxes on such
additional amount) shall equal the amount of such Taxes paid by such Person;
provided, however, that the applicable Borrower shall not be obligated to make
payment to the Lenders or the Agents (as the case may be) pursuant to this
sentence in respect of penalties or interest attributable to any Taxes, if
written demand therefor has not been made by such Lenders or the Agents within
60 days from the date on which such Lenders or the Agents knew of the
imposition of Taxes by the relevant taxing authority or for any additional
imposition which may arise from the failure of the Lenders or the Agents to
apply payments in accordance with the applicable tax law after any Borrower has
made the payments required hereunder; provided, further, however, that the
Borrowers shall not be required to pay any such additional amounts in respect
of any amounts payable to any Non-U.S. Lender or any Agent that is not
organized under the laws of the United States or a state thereof to the extent
the related Tax is imposed as a result of such Lender or Agent failing to
comply with the requirements of clause (b) of Section 4.6.  After a Lender or
an Agent (as the case may be) learns of the imposition of Taxes, such Lender or
Agent will act in good faith to notify the Borrowers of their obligations
hereunder as soon as reasonably possible.

                      If any Borrower fails to pay any Taxes when due to the
appropriate taxing authority or fails to remit to the Administrative Agent, for
the account of the respective Lenders, the required receipts or other required
documentary evidence, such Borrower shall indemnify the Lenders for any
incremental Taxes, interest or penalties that may become payable by any Lender
as a result of any such failure.

                      (b)  Each Non-U.S. Lender shall, (i) on or prior to the
date of the execution and delivery of this Agreement, in the case of each
Lender listed on the signature pages hereof, or, in the case of an Assignee
Lender, on or prior to the date it becomes a Lender, execute and deliver to the
Company and the Administrative Agent, two or more (as the Company or the Agents
may reasonably request) United States Internal Revenue Service Forms 4224 or
Forms 1001 (or successor forms) or, solely if such Lender is claiming exemption
from United States withholding tax under Section 871(h) or 881(c) of the Code
with respect to





                                      101
<PAGE>   110
payments of "portfolio interest", United States Internal Revenue Service Forms
W-8 and a certificate signed by a duly authorized officer of such Lender
representing that such Lender is not a "bank" (within the meaning of Section
881(c)(3)(A) of the Code), is not a 10 percent shareholder (within the meaning
of Section 871(h)(3)(B) of the Code) with respect to the Company and is not a
controlled foreign corporation with respect to which the Company is a related
person (within the meaning of Section 864(d)(4) of the Code) or such other
forms or documents (or successor forms or documents), appropriately completed,
establishing that payments to such Lender are exempt from withholding or
deduction of Taxes imposed by the United States; and (ii) deliver to the
Company and the Administrative Agent two further copies of any such form or
documents on or before the date that any such form or document expires or
becomes obsolete and after the occurrence of any event requiring a change in
the most recent such form or document previously delivered by it to the
Company.  Each Lender and each Agent agrees, to the extent reasonable and
without material cost to it, to provide to the applicable Borrower and the
Administrative Agent such other applicable forms or certificates that would
reduce or eliminate any Tax otherwise applicable.

                      (c)  If the Company determines in good faith that a
reasonable basis exists for contesting the imposition of a Tax with respect to
a Lender or either of the Agents, the relevant Lender or Agent, as the case may
be, shall reasonably cooperate with the Borrowers in challenging such Tax at
the Borrowers' expense if requested by the Company; provided, however, that
nothing in this Section 4.6 shall require any Lender to submit to the Company
or any other Person any tax returns or any part thereof, or to prepare or file
any tax returns other than as such Lender in its sole discretion shall
determine.

                      (d)  If a Lender or an Agent shall receive a refund
(including any offset or credits) from a taxing authority (as a result of any
error in the imposition of Taxes by such taxing authority) of any Taxes paid by
any Borrower pursuant to clause (a) above, such Lender or the Agent (as the
case may be) shall promptly pay such Borrower the amount so received, with
interest from the taxing authority with respect to such refund, net of any tax
liability incurred by such Lender or Agent that is attributable to the receipt
of such refund and such interest.

                      (e)  Each Lender and each Agent agrees, to the extent
reasonable and without material cost to it, to cooperate with the Borrowers to
minimize any amounts payable by the Borrowers under this Section 4.6; provided,
however, that nothing in this Section 4.6 shall require any Lender to take any
action which, in the sole discretion of such Lender, is inconsistent with its
internal policy and legal and regulatory restrictions.





                                      102
<PAGE>   111
                      SECTION 4.7.  Payments, Computations, etc.  Unless
otherwise expressly provided, all payments by or on behalf of the Borrowers
pursuant to this Agreement or any other Loan Document shall be made by the
Borrowers to the Administrative Agent for the pro rata account of the Lenders,
Agents or Arranger, as applicable, entitled to receive such payment.  All such
payments required to be made to the Administrative Agent shall be made, without
setoff, deduction or counterclaim, not later than 1:00 p.m., New York time, on
the date due, in same day or immediately available funds, to such account as
the Administrative Agent shall specify from time to time by notice to the
Company and the applicable Borrower.  Funds received after that time shall be
deemed to have been received by the Administrative Agent on the next succeeding
Business Day.  The Administrative Agent shall promptly remit in same day funds
to each Lender, Agent or Arranger, as the case may be, its share, if any, of
such payments received by the Administrative Agent for the account of such
Lender, Agent or Arranger, as the case may be.  All interest and fees shall be
computed on the basis of the actual number of days (including the first day but
excluding the last day) occurring during the period for which such interest or
fee is payable over a year comprised of 360 days (or, in the case of interest
on a Base Rate Loan, 365 days or, if appropriate, 366 days).  Whenever any
payment to be made shall otherwise be due on a day which is not a Business Day,
such payment shall (except as otherwise required by clause (i) of the
definition of the term "Interest Period") be made on the next succeeding
Business Day and such extension of time shall be included in computing interest
and fees, if any, in connection with such payment.

                      SECTION 4.8.  Sharing of Payments.  If any Lender shall
obtain any payment or other recovery (whether voluntary, involuntary, by
application of setoff or otherwise) on account of any Loan or Reimbursement
Obligations (other than pursuant to the terms of Sections 4.3, 4.4 and 4.5) in
excess of its pro rata share of payments then or therewith obtained by all
Lenders entitled thereto, such Lender shall purchase from the other Lenders
such participation in the Credit Extensions made by them as shall be necessary
to cause such purchasing Lender to share the excess payment or other recovery
ratably with each of them; provided, however, that if all or any portion of the
excess payment or other recovery is thereafter recovered from such purchasing
Lender, the purchase shall be rescinded and each Lender which has sold a
participation to the purchasing Lender shall repay to the purchasing Lender the
purchase price to the ratable extent of such recovery together with an amount
equal to such selling Lender's ratable share (according to the proportion of
(i) the amount of such selling Lender's required repayment to the purchasing
Lender in respect of such recovery, to (ii) the total amount so recovered from
the purchasing Lender) of any interest or other amount paid or payable by the
purchasing Lender in respect of the total amount so recovered.  The Borrowers
agree that any Lender so purchasing a participation from another Lender
pursuant to this Section may, to the fullest extent permitted by law, exercise
all its





                                      103
<PAGE>   112
rights of payment (including pursuant to Section 4.9) with respect to such
participation as fully as if such Lender were the direct creditor of the
applicable Borrower in the amount of such participation.  If under any
applicable bankruptcy, insolvency or other similar law, any Lender receives a
secured claim in lieu of a setoff to which this Section applies, such Lender
shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Lenders entitled
under this Section to share in the benefits of any recovery on such secured
claim.

                      SECTION 4.9.  Setoff.  Each Lender shall, upon the
occurrence of any Event of Default described in clauses (b) through (d) of
Section 8.1.9 with respect to any Obligor (other than Immaterial Subsidiaries)
or, with the consent of the Required Lenders, upon the occurrence of any other
Event of Default, to the fullest extent permitted by law, have the right to
appropriate and apply to the payment of the Obligations then due to it from
such Borrower, and (as security for such Obligations) each Borrower hereby
grants to each Lender a continuing security interest in, any and all balances,
credits, deposits, accounts or moneys of such Borrower (general or special,
matured or unmatured and in whatever currencies denominated) then or thereafter
maintained with or otherwise held by such Lender; provided, however, that any
such appropriation and application shall be subject to the provisions of
Section 4.8.  Each Lender agrees promptly to notify the applicable Borrower,
the Company and the Administrative Agent after any such setoff and application
made by such Lender; provided, however, that the failure to give such notice
shall not affect the validity of such setoff and application.  The rights of
each Lender under this Section are in addition to other rights and remedies
(including other rights of setoff under applicable law or otherwise) which such
Lender may have.

                      SECTION 4.10.  Mitigation.  Each Lender agrees that if it
makes any demand for payment under Sections 4.3, 4.4, 4.5 or 4.6, or if any
adoption or change of the type described in Section 4.1 shall occur with
respect to it, it will use reasonable efforts (consistent with its internal
policy and legal and regulatory restrictions and so long as such efforts would
not be disadvantageous to it, as determined in its sole discretion) to
designate a different lending office if the making of such a designation would
reduce or obviate the need for a Borrower to make payments under Section 4.3,
4.4, 4.5 or 4.6, or would eliminate or reduce the effect of any adoption or
change described in Section 4.1.





                                      104
<PAGE>   113
                      SECTION 4.11.  Replacement of Lenders.  Each Lender
hereby severally agrees as set forth in this Section.  If any Lender (a
"Subject Lender") (i) makes demand upon any Borrower for (or if any Borrower is
otherwise required to pay) amounts pursuant to Section 4.3, 4.5 or 4.6, (ii)
gives notice pursuant to Section 4.1 requiring a conversion of such Subject
Lender's LIBO Rate Loans to Base Rate Loans or any change in the basis upon
which interest is to accrue in respect of such Subject Lender's LIBO Rate Loans
or suspending such Lender's obligation to make Loans as, or to convert Loans
into, LIBO Rate Loans, (iii) becomes a Non-Consenting Lender or (vi) becomes a
Non-Funding Lender, the Company may, within 180 days of receipt by such
Borrower of such demand or notice (or the occurrence of such other event
causing any Borrower to be required to pay such compensation) or within 180
days of such Lender becoming a Non-Consenting Lender or a Non-Funding Lender,
as the case may be, give notice (a "Replacement Notice") in writing to the
Agents and such Subject Lender of its intention to replace such Subject Lender
with a financial institution (a "Replacement Lender") designated in such
Replacement Notice.  If the Agents shall, in the exercise of their reasonable
discretion and within 30 days of their receipt of such Replacement Notice,
notify the Company and such Subject Lender in writing that the designated
financial institution is satisfactory to the Agents (such consent not being
required where the Replacement Lender is already a Lender), then such Subject
Lender shall, subject to the payment of any amounts due pursuant to Section
4.4, assign, in accordance with Section 11.11.1, all of its Commitments, Loans
and other rights and obligations under this Agreement and all other Loan
Documents (including, without limitation, Reimbursement Obligations) to such
designated financial institution; provided, however, that (i) such assignment
shall be without recourse, representation or warranty and shall be on terms and
conditions reasonably satisfactory to such Subject Lender and such designated
financial institution and (ii) the purchase price paid by such designated
financial institution shall be in the amount of such Subject Lender's Loans and
its Percentage in respect of any Revolving Loan Commitment under which there
are outstanding Reimbursement Obligations of such Reimbursement Obligation,
together with all accrued and unpaid interest and fees in respect thereof, plus
all other amounts (including the amounts demanded and unreimbursed under
Sections 4.3, 4.5 and 4.6), owing to such Subject Lender hereunder.  Upon the
effective date of an assignment described above, the designated financial
institution or Replacement Lender shall become a "Lender" for all purposes
under this Agreement and the other Loan Documents.

                        CONDITIONS TO CREDIT EXTENSIONS

                      SECTION 5.1.  Initial Credit Extension.  The obligations
of the Lenders and the Issuers to fund the initial Credit Extension shall be
subject to the prior or concurrent satisfaction of each of the conditions
precedent set forth in this Section 5.1.

                      SECTION 5.1.1.  Resolutions, etc.  The Agents shall have
received from each Obligor a certificate, dated the date of the initial Credit
Extension, of its Secretary or Assistant Secretary as to (i) resolutions of its
Board of Directors then in full force and effect authorizing the execution,
delivery and performance of each Loan Document to be executed by it, and (ii)
the incumbency and signatures of those of its officers authorized to act with
respect to each Loan Document executed by it, upon which certificate each Agent
and each Lender may conclusively rely until it shall have received a further
certificate of the Secretary or Assistant Secretary of such Obligor canceling
or amending such prior certificate.

                      SECTION 5.1.2.  Transaction Documents.  The Agents shall
have received (with copies for each Lender that shall have expressly requested
copies thereof) copies of fully executed versions of the Transaction Documents,
certified to be true and complete copies thereof by an Authorized Officer of
the Company.  The Merger Agreement shall be in full force and effect and shall
not have been modified or waived in any material respect, nor shall there have
been any forbearance to exercise any material rights with respect to any of the
terms or provisions relating to the conditions to the consummation of the
Merger set forth in the Merger Agreement unless otherwise agreed to by the
Required Lenders.

                      SECTION 5.1.3.  Consummation of Merger.  The Agents shall
have received evidence satisfactory to each of them that all actions necessary
to consummate the Merger (including the filing of the Certificate of Merger
with the Secretary of State of the State of Delaware) shall have been taken in
accordance with Section 251 of the Delaware General Corporation Law.

                      SECTION 5.1.4.  Closing Date Certificate.  Each of the

                             (b)  contravene any contractual restriction (other
                      than any contractual restriction that shall have been

                      governmental regulation or court decree or order binding
                      on or affecting the Company or any such Obligor, where
                      such contravention, individually or in the aggregate,

<PAGE>   123

Investment Company Act of 1940, as amended, or a "holding company", or a
"subsidiary company" of a "holding company", or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company", within the

                      SECTION 6.4.  Validity, etc.  This Agreement constitutes,
and each other Loan Document executed by any Borrower will, on the due
execution and delivery thereof, constitute, the legal, valid and binding
obligations of each Borrower party thereto, enforceable in accordance with
their respective terms; and each Loan Document executed pursuant hereto by each
other Obligor will, on the due execution and delivery thereof by such Obligor,
be the legal, valid and binding obligation of such Obligor enforceable in

subject to the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally, general equitable principles (whether considered
in a proceeding in equity or at law) and an implied covenant of good faith and
fair dealing.

                      SECTION 6.5.  Financial Information.  The Company has
delivered to the Agents and each Lender copies of (i) the Base Financial
Statements and (ii)  the Pro Forma Balance Sheet.  Each of the financial
statements described above has been prepared in accordance with GAAP
consistently applied (in the case of clause (i)) and, in the case of clause
(ii), on a basis substantially consistent with the basis used to prepare the
financial statements referred to in clause (i), and (in the case of clause (i))
present fairly the consolidated financial condition of the corporations covered
thereby as at the date thereof and the results of their operations for the
periods then ended and (in the case of clause (ii)) include appropriate pro
forma adjustments to give pro forma effect to the Transaction.

                      SECTION 6.6.  No Material Adverse Effect.  Since December
31, 1997, no facts, events or conditions have occurred which constitute a
Material Adverse Effect.

                      SECTION 6.7.  Litigation, Labor Controversies, etc.
There is no pending or, to the knowledge of the Company, threatened litigation,
action, proceeding or governmental investigation affecting any Obligor, or any
of their respective properties, businesses, assets or revenues, which could
reasonably be expected to result in a Material Adverse Effect except as
disclosed in Item 6.7 ("Litigation") of the Disclosure Schedule.  No
development





                                      115
<PAGE>   124
has occurred in any litigation, action, labor controversy, arbitration or
governmental investigation or other proceeding disclosed in Item 6.7
("Litigation") of the Disclosure Schedule which could reasonably be expected to
have a Material Adverse Effect.

                      SECTION 6.8.  Subsidiaries.  The Company has only those
Subsidiaries (i) which are identified in Item 6.8 ("Existing Subsidiaries") of
the Disclosure Schedule, or (ii) which are permitted to have been acquired in
accordance with Section 7.2.5 or 7.2.8.  Each Foreign Borrower is a
wholly-owned Subsidiary of the Company.

                      SECTION 6.9.  Ownership of Properties.  Except to the
extent that the failure to do so could not reasonably be expected to have a
Material Adverse Effect, the Company and each of its Subsidiaries owns good
title to, or leasehold interests in, all of its properties and assets (other
than insignificant properties and assets), real and personal, tangible and
intangible, of any nature whatsoever (including patents, trademarks, trade
names, service marks and copyrights), free and clear of all Liens or material
claims (including material infringement claims with respect to patents,
trademarks, copyrights and the like), except as permitted pursuant to Section
7.2.3.

                      SECTION 6.10.  Taxes.  Each of Holdco, the Company and
each of their respective Subsidiaries has filed all federal and other material
tax returns required by law to have been filed by it and has paid all material
taxes and governmental charges thereby shown to be owing, except any such taxes
or charges which are being contested in good faith by appropriate proceedings
and for which adequate reserves in accordance with GAAP shall have been set
aside on its books.

                      SECTION 6.11.  Pension and Welfare Plans.  During the
twelve-consecutive-month period prior to the date of the execution and delivery
of this Agreement, no steps have been taken to terminate any Pension Plan, and
no contribution failure has occurred with respect to any Pension Plan
sufficient to give rise to a Lien under section 302(f) of ERISA, which, in
either case, is reasonably expected to lead to a liability to such Pension Plan
in excess of $10,000,000.  No condition exists or event or transaction has
occurred with respect to any Pension Plan which could reasonably be expected to
result in the incurrence by the Company or any member of the Controlled Group
of any material liability, fine or penalty other than such condition, event or
transaction which would not reasonably be expected to have a Material Adverse
Effect.  Except as disclosed in Item 6.11 ("Employee Benefit Plans") of the
Disclosure Schedule or otherwise approved by the Agents (such approval not to
be unreasonably withheld or delayed), since the date of the last financial
statement the Company has not increased any contingent liability with respect
to any post-retirement benefit under a





                                      116
<PAGE>   125
Welfare Plan, other than liability for continuation coverage described in Part
6 of Subtitle B of Title I of ERISA, except as would not have Material Adverse
Effect.

                      SECTION 6.12.  Environmental Warranties.  Except as set
forth in Item 6.12 ("Environmental Matters") of the Disclosure Schedule or as,
individually or in the aggregate, could not reasonably be expected to have a
Material Adverse Effect:

                             (a)  all facilities and property owned or leased
                      by the Company or any of its Subsidiaries are in
                      compliance with all Environmental Laws;

                             (b)  there are no pending or threatened

                                  (i)  written claims, complaints, notices or
                             requests for information received by the Company
                             or any of its Subsidiaries with respect to any
                             alleged violation of any Environmental Law, or

                                  (ii)  written complaints, notices or
                             inquiries to the Company or any of its
                             Subsidiaries regarding potential liability under
                             any Environmental Law;

                             (c)  to the knowledge of the Company, there have
                      been no Releases of Hazardous Materials at, on or under
                      any property now or previously owned or leased by the
                      Company or any of its Subsidiaries;

                             (d)  the Company and its Subsidiaries have been
                      issued and are in compliance with all permits,
                      certificates, approvals, licenses and other
                      authorizations relating to environmental matters and
                      necessary or desirable for their businesses;

                             (e)  no property now or, to the best knowledge of
                      the Company, previously owned or leased by the Company or
                      any of its Subsidiaries is listed or, to the knowledge of

                      listing (with respect to owned property only) on the
                      National Priorities List pursuant to CERCLA, on the
                      CERCLIS or on any similar state list of sites requiring
                      investigation or clean-up;

                      are no underground storage tanks, active or abandoned,
                      including petroleum storage tanks, on or under any
                      property now or previously owned or leased by the Company
                      or any of its Subsidiaries;

                      state or local enforcement actions or other
                      investigations;

                             (h)  to the knowledge of the Company, there are no
                      polychlorinated biphenyls or friable asbestos present in
                      a manner or condition requiring remedial action to comply
                      with any Environmental Law at any property now or
                      previously owned or leased by the Company or any

                      previously owned or leased by the Company or any of its
                      Subsidiaries which, with the passage of time, or the
                      giving of notice or both, would give rise to liability to
                      the Company or any of its Subsidiaries under any
                      Environmental Law.

Company nor Holdco is engaged in the business of extending credit for the
purpose of purchasing or carrying margin stock, and no proceeds of any Credit
Extension will be used in violation of F.R.S. Board Regulation G, U or X.
Terms for which meanings are provided in F.R.S. Board Regulation G, U or X or
any regulations substituted therefor, as from time to time in effect, are used
in this Section with such meanings.

                      SECTION 6.14.  Accuracy of Information.  All material
factual information concerning the financial condition, operations or prospects

contemporaneously furnished by or on behalf of the Company in writing to the

with this Agreement or any transaction contemplated hereby or with respect to
the Transaction is, and all other such factual information hereafter furnished
by or on behalf of the Company or any of its Subsidiaries to the Agents, the
Arranger, any Issuer or any Lender will be, taken as a whole, true and accurate
in every material respect on the date as of which such information is dated or
certified and such information is not, or shall not be, taken as a whole, as
the case may be, incomplete by omitting to state any fact necessary to make
such information not materially misleading.

                      Any term or provision of this Section to the contrary
notwithstanding, insofar as any of the factual information described above
includes assumptions, estimates, projections or





                                      118
<PAGE>   127
opinions, no representation or warranty is made herein with respect thereto;
provided, however, that to the extent any such assumptions, estimates,
projections or opinions are based on factual matters, the Company has reviewed
such factual matters and nothing has come to its attention in the context of
such review which would lead it to believe that such factual matters were not
or are not true and correct in all material respects or that such factual
matters omit to state any material fact necessary to make such assumptions,
estimates, projections or opinions not misleading in any material respect.

                      SECTION 6.15.  Solvency.  The Transaction (including the

Borrowers of the Indebtedness represented by the Subordinated Notes, the

Credit Extensions) will not involve or result in any fraudulent transfer or
fraudulent conveyance under the provisions of Section 548 of the Bankruptcy
Code (11 U.S.C. Section 101 et seq., as from time to time hereafter amended,
and any successor or similar statute) or any applicable state law respecting
fraudulent transfers or fraudulent conveyances.  On the Closing Date, after
giving effect to the Transaction, the Company is Solvent.

                      maintenance and preservation of its corporate existence
                      and qualification as a foreign corporation, except where
                      the failure to so qualify could not reasonably be

Subsidiaries to, maintain, preserve, protect and keep its properties (other

(ordinary wear and tear excepted), and make necessary and proper repairs,
renewals and replacements so that its business carried on in connection
therewith may be properly conducted at all times unless the Company determines
in good faith that the continued maintenance of any of its properties is no
longer economically desirable.

cause each of its Subsidiaries to, maintain or cause to be maintained with

Officer of the Company setting forth the nature and extent of all insurance

independent public accountant to discuss the Company's financial matters with
each Issuer and each Lender or its representatives whether or not any
representative of the Company is present, so long as the Company has been
afforded a reasonable opportunity to be present) and to examine, and photocopy
extracts from, any of its books or other corporate records.  The cost and
expense of each such visit shall be borne by the applicable Agent or Lender.

                      SECTION 7.1.6.  Environmental Covenant.  The Company will
and will cause each of its Subsidiaries to,

                             (a)  use and operate all of its facilities and
                      properties in compliance with all Environmental Laws,

                      therewith, and handle all Hazardous Materials in
                      compliance with all applicable Environmental Laws, in
                      each case except where the failure to comply with the
                      terms of this clause would not reasonably be expected to
                      have a Material Adverse Effect;

                             (b)  promptly notify the Agents and provide copies
                      of all written claims, complaints, notices or inquiries
                      relating to the condition of its facilities and
                      properties or compliance with Environmental Laws which
                      relate to environmental matters which would have, or
                      would reasonably be expected to have, a Material Adverse
                      Effect, and promptly cure and have dismissed with
                      prejudice any material actions and proceedings relating
                      to compliance with Environmental Laws, except to the
                      extent being diligently contested in good faith by
                      appropriate proceedings and for which adequate reserves
                      in accordance with GAAP have been set aside on its books;
                      and

                             (c)  provide such information and certifications
                      which the Agents may reasonably request from time to time

                      SECTION 7.1.7.  Future Subsidiaries.  Upon any Person
(other than the Receivables Subsidiaries) becoming, after the Closing Date, a
Subsidiary of the Company, or (in the case of clause (b) below only) upon the
Company or any U.S. Subsidiary (other than the Receivables Subsidiaries)
acquiring additional Capital Stock of any existing Subsidiary, the Company
shall notify the Agents of such acquisition, and

                             (a)  the Company shall promptly cause any such
                      Subsidiary that is a U.S. Subsidiary to execute and
                      deliver to the Administrative Agent, with counterparts
                      for each Lender, a supplement to the Subsidiary
                      Co-Obligation Agreement and Guaranty and a supplement to
                      the Subsidiary Security Agreement (and, if such
                      Subsidiary owns any real property, to the extent required
                      by clause (b) of Section 7.1.8, a Mortgage), together
                      with Uniform Commercial Code financing statements (Form
                      UCC-1) executed and delivered by such U.S. Subsidiary
                      naming such U.S. Subsidiary as the debtor and the
                      Administrative Agent as the secured party, or other
                      similar instruments or documents, in appropriate form for
                      filing under the Uniform Commercial Code and any other
                      applicable recording statutes, in the case of real
                      property, of all jurisdictions as may be necessary or, in
                      the reasonable opinion of the Administrative Agent,
                      desirable to perfect the security interest of the
                      Administrative Agent pursuant to the Subsidiary Security
                      Agreement or a Mortgage, as the case may be (other than
                      the perfection of security interests in motor vehicles);
                      and

                             (b)  the Company shall promptly deliver, or cause
                      to be delivered, to the Administrative Agent under a
                      Pledge Agreement (or a supplement thereto) certificates
                      (if any) representing all of the issued and outstanding
                      shares of Capital Stock of such Subsidiary owned by the
                      Company or any U.S. Subsidiary of the Company, as the
                      case may be, along with undated stock powers for such
                      certificates, executed in blank, or, if any securities
                      subject thereto are uncertificated securities, the
                      Administrative Agent shall have obtained "control" (as
                      defined in the Uniform Commercial Code applicable to such
                      securities) over such securities, or other appropriate
                      steps shall have been taken under applicable law
                      resulting in the perfection of the security interest
                      granted in such securities in favor of the Administrative
                      Agent pursuant to the terms of such Pledge Agreement;

together, in each case, with such opinions, in form and substance and from
counsel satisfactory to the Agents, as the Agents may reasonably require;
provided, however, that notwithstanding the foregoing, no Non-U.S. Subsidiary
shall be required to execute and





                                      124
<PAGE>   133
deliver a Mortgage, a supplement to the Subsidiary Co-Obligation Agreement and
Guaranty, a supplement to the Security Agreement or a supplement to a Pledge
Agreement, nor will the Company or any Subsidiary of the Company be required to
deliver in pledge pursuant to a Pledge Agreement in excess of 65% of the total
combined voting power of all classes of Capital Stock of a Non-U.S. Subsidiary
entitled to vote.

                      SECTION 7.1.8.  Future Leased Property and Future
Acquisitions of Real Property; Future Acquisition of Other Property.  (a)
Prior to entering into any new lease of real property or renewing any existing
lease of real property following the Closing Date, the Company shall, and shall
cause each of its U.S. Subsidiaries to, use its (and their) commercially
reasonable efforts (which shall not require the expenditure of cash or the
making of any material concessions under the relevant lease) to deliver to the
Administrative Agent a Waiver executed by the lessor of any real property that
is to be leased by the Company or such U.S. Subsidiary for a term in excess of
one year in any state which by statute grants such lessor a "landlord's" (or
similar) Lien which is superior to the Administrative Agent's, to the extent
the value of any personal property of the Company or its U.S. Subsidiaries to
be held at such leased property exceeds (or it is anticipated that the value of
such personal property will, at any point in time during the term of such
leasehold term, exceed) $6,000,000.

                      (b)  In the event that the Company or any of its U.S.
Subsidiaries shall acquire any real property having a value as determined in
good faith by the Administrative Agent in excess of $3,000,000 in the
aggregate, the Company or the applicable U.S. Subsidiary shall, promptly after
such acquisition, execute a Mortgage and provide the Administrative Agent with
(i) evidence of the completion (or satisfactory arrangements for the
completion) of all recordings and filings of such Mortgage as may be necessary
or, in the reasonable opinion of the Administrative Agent, desirable
effectively to create a valid, perfected, first priority Lien, subject to the
Liens permitted by Section 7.2.3, against the properties purported to be
covered thereby, (ii) mortgagee's title insurance policies in favor of the
Agents and the Lenders in amounts and in form and substance and issued by
insurers, reasonably satisfactory to the Agents, with respect to the property
purported to be covered by such Mortgage, insuring that title to such property
is indefeasible and that the interests created by the Mortgage constitute valid
first Liens thereon free and clear of all defects and encumbrances other than
as permitted by Section 7.2.3 or as approved by the Agents, and such policies
shall also include, to the extent available, a revolving credit endorsement and
such other endorsements as the Agents shall reasonably request and shall be
accompanied by evidence of the payment in full of all premiums thereon, and
(iii) such other approvals, opinions, or documents as the Agents may reasonably
request.

<PAGE>   134
                      (c)  In accordance with the terms and provisions of the
Loan Documents, the Company and each U.S.  Subsidiary (other than the
Receivables Subsidiary) shall provide the Agents with evidence of all
recordings and filings as may be necessary or, in the reasonable opinion of the
Administrative Agent, desirable to create a valid, perfected, first priority
Lien, subject to the Liens permitted by Section 7.2.3, against all property
acquired after the Closing Date (excluding motor vehicles and (except to the
extent required under clause (b) of Section 7.1.8) leases of and fee interests
in real property) and not otherwise subject to Sections 7.1.11 and 7.1.12.

                      SECTION 7.1.9.  Use of Proceeds, etc.  The Borrowers
shall

                             (a)  apply the proceeds of the Loans

                                  (i) in the case of the Term Loans and the
                             Revolving Loans made on the Closing Date, to pay,
                             in part, through the Closing Date Dividend and/or
                             the Intercompany Loan to Holdco, the cash portion
                             of the obligations of Holdco in connection with

                      SECTION 7.2.7.  Capital Expenditures, etc.  With respect
to Capital Expenditures, the parties covenant and agree as follows:

                             (a)  The Company will not, and will not permit any
                      of its Subsidiaries to, make or commit to make Capital
                      Expenditures in any Fiscal Year, except Capital
                      Expenditures (i) which do not aggregate in excess of
                      $25,000,000 in such Fiscal Year plus (ii) an additional
                      aggregate amount equal to $20,000,000 over the term of
                      this Agreement; provided, however, that to the extent the
                      amount of Capital Expenditures permitted to be made in
                      any Fiscal Year pursuant to this Section exceeds the
                      aggregate amount of Capital Expenditures actually made
                      during such Fiscal Year, such excess amount (up to an
                      aggregate of 50% of the amount of Capital Expenditures
                      permitted for such Fiscal Year, without giving effect to
                      this proviso) may be carried forward to (but only to) the
                      next succeeding Fiscal Year (any such amount to be
                      certified by the Company to the Agents in the Compliance
                      Certificate delivered for the last Fiscal Quarter of such
                      Fiscal Year, and any such amount carried forward to a
                      succeeding Fiscal Year shall be deemed to be used prior
                      to the Company and its Subsidiaries using the amount of
                      Capital Expenditures permitted by this Section in such
                      succeeding Fiscal Year, without giving effect to such
                      carry-forward).

                             (b)  The parties acknowledge and agree that the
                      permitted Capital Expenditure level set forth in clause
                      (a) above shall be exclusive of the amount of Capital
                      Expenditures actually made with cash capital
                      contributions (including the proceeds of issuances of
                      equity securities) made, directly or indirectly, by any
                      Person other than the Company and its Subsidiaries, after
                      the Closing Date to the Company or any of its
                      Subsidiaries and specifically identified in a certificate
                      delivered by an Authorized Officer of the Company to the
                      Agents on or about the time such capital contribution is
                      made; provided, that, to the extent any such cash capital
                      contributions constitute Net Equity Proceeds arising from
                      the issuance by Holdco of its Capital Stock, only that
                      portion of such Net Equity Proceeds which are not
                      required to be applied as a prepayment pursuant to clause
                      (e) of Section 3.1.1 may be used for Capital Expenditures
                      pursuant to this clause (b).

                      SECTION 7.2.8.  Consolidation, Merger, etc.  The Company
will not, and will not permit any of its Subsidiaries to, liquidate or
dissolve, consolidate with, or merge into or with, any other corporation, or
purchase or otherwise acquire all or substantially all of the assets of any
Person (or of any division thereof) except





                                      141

                             (a)  any such Subsidiary may liquidate or dissolve
                      voluntarily into, and may merge with and into, the
                      Company (so long as the Company is the surviving
                      corporation of such combination or merger) or any other
                      Subsidiary, and the assets or stock of any Subsidiary may
                      be purchased or otherwise acquired by the Company or any
                      other Subsidiary; provided, that notwithstanding the
                      above, a Subsidiary may only liquidate or dissolve into,
                      or merge with and into, another Subsidiary of the Company
                      if, after giving effect to such combination or merger,
                      the Company continues to own (directly or indirectly),
                      and the Administrative Agent continues to have pledged to
                      it pursuant to a Pledge Agreement, a percentage of the
                      issued and outstanding shares of Capital Stock (on a
                      fully diluted basis) of the Subsidiary surviving such
                      combination or merger that is equal to or in excess of
                      the percentage of the issued and outstanding shares of
                      Capital Stock (on a fully diluted basis) of the
                      Subsidiary that does not survive such combination or
                      merger that was (immediately prior to the combination or
                      merger) owned by the Company or pledged to the
                      Administrative Agent;

                             (b)  so long as no Default has occurred and is
                      continuing or would occur after giving effect thereto,
                      the Company or any of its Subsidiaries (other than the
                      Receivables Subsidiaries) may purchase all or
                      substantially all of the assets of any Person (or any
                      division thereof) not then a Subsidiary, or acquire such
                      Person by merger, if permitted (without duplication)
                      pursuant to Section 7.2.7 or clause (e), (f), (m) or (r)
                      of Section 7.2.5;

                             (c)  the Company and its Subsidiaries may
                      consummate the Transaction; and

                             (d)  the Company may merge into a newly-formed
                      corporation incorporated under the laws of the United
                      States or any State for the purpose of reincorporating in
                      such State so long as (i) the shareholders of the
                      surviving corporation immediately after such merger are
                      the same as the shareholders of the Company immediately
                      prior to such merger, (ii) immediately before and after
                      such merger, no Default shall have occurred and be
                      continuing and (iii) the corporation surviving such
                      merger shall assume, pursuant to documentation reasonably
                      satisfactory to the Agents, all of the obligations of the
                      Company under the Loan Documents.

will not, and will not permit any of its Subsidiaries to, sell, transfer,
license, lease, contribute or otherwise convey, or grant options, warrants or
other rights with respect to, all or any part of its assets, whether now owned

Subsidiaries) to any Person, unless

                             (a)  such sale, transfer, license, lease,
                      contribution or conveyance of such assets is (i) in the
                      ordinary course of its business (and does not constitute

                      conveyance of all or a substantial part of the Company's

                      sale, transfer, license, lease, contribution or
                      conveyance would be permitted by Section 7.2.11) or (iv)
                      a sale or transfer of accounts receivable and related
                      assets, or any interest therein, by the Company or any of
                      its Subsidiaries to a Receivables Subsidiary, or by a

                      Section 7.2.5, (ii) a Lien permitted under Section 7.2.3
                      or (iii) a Restricted Payment permitted under Section

                      other assets sold, transferred, leased, contributed or
                      conveyed pursuant to this clause (c) since the Closing
                      Date, does not exceed (individually or in the aggregate)
                      $20,000,000 in any Fiscal Year and (iii) an amount equal
                      to the Net Disposition Proceeds generated from such sale,

                      in the business of the Company and its Subsidiaries, or,
                      to the extent required thereunder, is applied to prepay
                      the Loans pursuant to the terms of Section 3.1.1 and

or remedies of the Lenders or the Company's or any other Obligor's ability to
perform hereunder or under any Loan Document, or materially increase the
obligations of the Company or any Subsidiary thereunder to the detriment of the
Lenders, or which would increase the cash consideration payable in respect of
the Merger or, in the case of the Merger Agreement, which would increase the
Company's or any of its Subsidiaries' obligations or liabilities, contingent or
otherwise (other than adjustments to the cash consideration payable in respect
of the Merger made pursuant to the terms of the Merger Agreement).

or cause, suffer or permit to exist any arrangement or contract with any of its
other Affiliates (other than any Obligor or any other Subsidiary of the
Company) unless such arrangement or contract is fair and equitable to the
Company or such Subsidiary and is an arrangement or contract of the kind which
would be entered into by a prudent Person in the position of the Company or
such Subsidiary with a Person which is not one of its Affiliates; provided,
however that the Company and its Subsidiaries shall be permitted to (i) enter
into and perform their obligations, or take any other actions contemplated or
permitted under the Transaction Documents, (ii) make any Restricted Payment
permitted under Section 7.2.6 and (iii) enter into and perform their

Subsidiaries to, enter into any agreement (other than the Loan Documents)
prohibiting

                             (a)  (i) the creation or assumption of any Lien
                      upon its properties, revenues or assets, whether now
                      owned or hereafter acquired (other than, (A) in the case
                      of any assets acquired with the proceeds of any

                      limitations in respect of the Subsidiary of the Company
                      that has incurred such Indebtedness and its assets;

                      appear in any court conducting any relevant proceeding
                      during such 60-day period to preserve, protect and defend
                      their rights under the Loan Documents;

                             (d)  permit or suffer to exist the commencement of
                      any bankruptcy, reorganization, debt arrangement or other
                      case or proceeding under any bankruptcy or insolvency
                      law, or any dissolution, winding up or liquidation
                      proceeding, in respect of the Company or any of its
                      Subsidiaries (other than Immaterial Subsidiaries which
                      are not Obligors) or any other Obligor, and, if any such
                      case or proceeding is not commenced by the Company or
                      such Subsidiary or such other Obligor, such case or
                      proceeding shall be consented to or acquiesced in by the
                      Company or such Subsidiary or such other Obligor or shall
                      result in the entry of an order for relief or shall
                      remain for 60 days undismissed, provided that the
                      Company, each Subsidiary and each other Obligor hereby
                      expressly authorizes the Agents, each Issuer and each
                      Lender to appear in any court conducting any such case or
                      proceeding during such 60-day period to preserve, protect

Company or any other Obligor shall, directly or indirectly, contest in any
manner the effectiveness, validity, binding nature or enforceability thereof;
or any Lien securing any Obligation shall, in whole or in part, cease to be a
perfected first priority Lien, subject only





                                      148
<PAGE>   157
to those exceptions expressly permitted by the Loan Documents, except to the
extent any event referred to above (a) relates to assets of the Company or any

                      SECTION 8.1.11.  Subordinated Notes.  The subordination

the Required Lenders, shall by notice to the Company declare all or any portion

                                   ARTICLE IX

                                   THE AGENTS

                      SECTION 9.1.  Actions.  Each Lender hereby appoints DLJ
as its Syndication Agent and ABN AMRO as its Administrative Agent under and for
purposes of this Agreement and each other Loan Document.  Each Lender
authorizes the Agents to act on behalf of such Lender under this Agreement and
each other Loan Document and, in the absence of other written instructions from
the Required Lenders received from time to time by the Agents (with respect to
which each of the Agents agrees that it will comply, except as otherwise
provided in this Section or as otherwise advised by counsel), to exercise such
powers hereunder and thereunder as are specifically delegated to or required of
the Agents by the terms hereof and thereof, together with such powers as may be
reasonably incidental thereto.  Each Lender authorizes the Administrative Agent
to act on behalf of such Lender as "Administrative Agent" pursuant to the
Intercreditor Agreement.  Each Lender hereby indemnifies (which indemnity
shall survive any termination of this Agreement) the Agents, ratably in
accordance with their respective Term Loans outstanding and Commitments (or, if
no Term Loans or Commitments are at the time outstanding and in effect, then
ratably in accordance with the principal amount of Term Loans held by such
Lender, and their respective Commitments as in effect in each case on the date
of the termination of this Agreement), from and against any and all
liabilities, obligations, losses, damages, claims, costs or expenses of any
kind or nature whatsoever which may at any time be imposed on, incurred by, or
asserted against, either of the Agents in any way relating to or arising out of
this Agreement and any other Loan Document, including reasonable attorneys'
fees, and as to which any Agent is not reimbursed by the Company or any other
Obligor (and without limiting the obligation of the Company or any other
Obligor to do so); provided, however, that no Lender shall be liable for the
payment of any portion of such liabilities, obligations, losses, damages,
claims, costs or expenses which are determined by a court of competent
jurisdiction in a final proceeding to have resulted solely from such Agent's
gross negligence or willful misconduct.  The Agents shall not be required to
take any action hereunder or under any other Loan Document, or to prosecute or
defend any suit in respect of this Agreement or any other Loan Document, unless
it is indemnified hereunder to its satisfaction.  If any indemnity in favor of
either of the Agents shall be or become, in such Agent's determination,
inadequate, the Agent may call for additional indemnification from the Lenders
and cease to do the acts indemnified against hereunder until such additional
indemnity is given.





                                      150
<PAGE>   159
                      SECTION 9.2.  Funding Reliance, etc.  Unless the
Administrative Agent shall have been notified by telephone, confirmed in
writing, by any Lender by 5:00 p.m., New York time, on the day prior to a
Borrowing or Disbursement with respect to a Letter of Credit pursuant to
Section 2.8.2 that such Lender will not make available the amount  which would
constitute its Percentage of such Borrowing on the date specified therefor, the
Administrative Agent may assume that such Lender has made such amount available
to the Administrative Agent and, in reliance upon such assumption, make
available to the applicable Borrower a corresponding amount.  If and to the
extent that such Lender shall not have made such amount available to the
Administrative Agent, such Lender severally agrees and the applicable Borrower
agrees to repay the Administrative Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date the
Administrative Agent made such amount available to such Borrower to the date
such amount is repaid to the Administrative Agent, at the interest rate
applicable at the time to Loans comprising such Borrowing.

                      SECTION 9.3.  Exculpation.  None of the Agents or the
Arranger nor any of their respective directors, officers, employees or agents
shall be liable to any Lender for any action taken or omitted to be taken by it
under this Agreement or any other Loan Document, or in connection herewith or
therewith, except for its own willful misconduct or gross negligence, nor
responsible for any recitals or warranties herein or therein, nor for the
effectiveness, enforceability, validity or due execution of this Agreement or
any other Loan Document, nor for the creation, perfection or priority of any
Liens purported to be created by any of the Loan Documents, or the validity,
genuineness, enforceability, existence, value or sufficiency of any collateral
security, nor to make any inquiry respecting the performance by any Borrower of
its obligations hereunder or under any other Loan Document.  Any such inquiry
which may be made by any Agent or any Issuer shall not obligate it to make any
further inquiry or to take any action.  The Agents and the Issuers shall be
entitled to rely upon advice of counsel concerning legal matters and upon any
notice, consent, certificate, statement or writing which the Agents or the
Issuers, as applicable, believe to be genuine and to have been presented by a
proper Person.

                      SECTION 9.4.  Successor.  The Syndication Agent may
resign as such upon one Business Day's notice to the Company and the
Administrative Agent.  The Administrative Agent may resign as such at any time
upon at least 30 days' prior notice to the Company and all Lenders.  If the
Administrative Agent at any time shall resign, the Required Lenders may, with
the prior consent of the Company (which consent shall not be unreasonably
withheld),





                                      151
<PAGE>   160
appoint another Lender as a successor Administrative Agent which shall
thereupon become the Administrative Agent hereunder.  If no successor
Administrative Agent shall have been so appointed by the Required Lenders, and
shall have accepted such appointment, within 30 days after the retiring
Administrative Agent's giving notice of resignation, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be one of the Lenders or a commercial banking
institution organized under the laws of the United States or a United States
branch or agency of a commercial banking institution, and having a combined
capital and surplus of at least $500,000,000.  Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall be entitled to receive from
the retiring Administrative Agent such documents of transfer and assignment as
such successor Administrative Agent may reasonably request, and shall thereupon
succeed to and become vested with all rights, powers, privileges and duties of
the retiring Administrative Agent, and the retiring Administrative Agent shall
be discharged from its duties and obligations under this Agreement.  After any
retiring Administrative Agent's resignation hereunder as the Administrative
Agent, the provisions of

                             (a)  this Article IX shall inure to its benefit as
                      to any actions taken or omitted to be taken by it while
                      it was the Administrative Agent under this Agreement; and

                             (b)  Section 11.3 and Section 11.4 shall continue
                      to inure to its benefit.

                      SECTION 9.5.  Credit Extensions by Each Agent and Issuer.
Each Agent and each Issuer shall have the same rights and powers with respect
to (i) in the case of the Agents, the Credit Extensions made by it or any of
its Affiliates and (ii) in the case of any Issuer, the Loans made by it or any
of its Affiliates as any other Lender and may exercise the same as if it were
not an Agent or an Issuer.  Each Agent, each Issuer and each of their
respective Affiliates may accept deposits from, lend money to, and generally
engage in any kind of business with any Borrower or any Subsidiary or Affiliate
of any Borrower as if such Agent or Issuer were not an Agent or Issuer
hereunder.

                      SECTION 9.6.  Credit Decisions.  Each Lender acknowledges
that it has, independently of each Agent, the Arranger, each Issuer and each
other Lender, and based on such Lender's review of the financial information of
the Borrowers, this Agreement, the other Loan Documents (the terms and
provisions of which being satisfactory to such Lender) and such other
documents, information and investigations as such Lender has deemed

document or instrument received for such Lender's account and copies of all
other communications received by the Administrative Agent from any Borrower for
distribution to the Lenders by the Administrative Agent in accordance with the
terms of this Agreement.

                      SECTION 9.8.  The Syndication Agent, the Documentation

contrary contained in this Agreement or any other Loan Document, the
Syndication Agent, the Documentation Agent and the Administrative Agent, each

no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or otherwise exist against  the
Syndication Agent, the Documentation Agent or the Administrative Agent, as
applicable, in such capacity except, in the case of the Agents,  as are

                      SECTION 10.1.  Guaranty.  The Company hereby absolutely,
unconditionally and irrevocably

                             (a)  guarantees the full and punctual payment when
                      due, whether at stated maturity, by required prepayment,
                      declaration, acceleration, demand or otherwise, of all
                      Obligations of each Foreign Borrower and each other
                      Obligor now or hereafter existing under this Agreement
                      and each other Loan Document to which such Foreign
                      Borrower and each other Obligor is or may become a party,
                      whether for principal, interest, fees, expenses or
                      otherwise (including all such amounts which would become
                      due but for the operation of the automatic stay under

                      operation of Sections 502(b) and 506(b) of the United
                      States Bankruptcy Code, 11 U.S.C. Section 502(b) and
                      Section 506(b)), and

                             (b)  indemnifies and holds harmless each Lender
                      for any and all costs and expenses (including reasonable
                      attorney's fees and expenses) incurred by such Lender or
                      such holder, as the case may be, in enforcing any rights
                      under this Article X;

This Article X constitutes a guaranty of payment when due and not of
collection, and the Company specifically agrees that it shall not be necessary
or required that any Lender exercise any right, assert any claim or demand or
enforce any remedy whatsoever against any Foreign Borrower or any other Obligor
(or any other Person) before or as a condition to the obligations of the
Company hereunder.

                      SECTION 10.2.  Acceleration of Obligations Hereunder.
The Company agrees that, in the event of the dissolution or insolvency of any
Foreign Borrower or any other Obligor, or the inability or failure of any
Foreign Borrower or any other Obligor to pay its debts as they become due, or
an assignment by any Foreign Borrower or any other Obligor for the benefit of
creditors, or the commencement of any case or proceeding in respect of any
Foreign Borrower or any other Obligor under any bankruptcy, insolvency or
similar laws, and if such event shall occur at a time when any of the
Obligations of any Foreign Borrower or any other Obligor may not then be due
and payable, the Company agrees that it will pay to the Lenders forthwith the
full amount which would be payable hereunder by such Foreign Borrower if all
such Obligations were then due and payable.  The foregoing provisions of this
Section 10.2 shall not be applicable if the dissolution, insolvency or other
events described above relate to an Immaterial Subsidiary.

                      SECTION 10.3.  Obligations Hereunder Absolute, etc.  The
obligations of the Company under this Article X shall in all respects be a
continuing, absolute, unconditional and irrevocable guaranty of payment, and
shall remain in full force and effect until all Obligations of all Foreign
Borrowers and each other Obligor have been paid in full and all Commitments
shall have terminated.  The Company guarantees that the Obligations of the
Foreign Borrowers and each other Obligor will be paid strictly in accordance
with the terms of this Agreement and each other Loan Document under which they
arise, regardless of any law, regulation or order now or hereafter in effect in
any jurisdiction affecting any of such terms or the rights of any Lender or any
holder of any Note with respect thereto.  The liability of the Company under
this Article X shall be absolute, unconditional and irrevocable irrespective
of:

                             (a)  any lack of validity, legality or
                      enforceability of other provisions of this Agreement or
                      any other Loan Document;

                             (b)  the failure of any Lender

                                  (i)  to assert any claim or demand or to
                             enforce any right or remedy against any Foreign
                             Borrower, any other Obligor or any other Person
                             (including any other guarantor) under the
                             provisions of this Agreement, any other Loan
                             Document or otherwise, or

                                  (ii)  to exercise any right or remedy against
                             any other guarantor of, or collateral securing,
                             any Obligations of any Foreign Borrower or any
                             other Obligor;

                             (c)  any change in the time, manner or place of
                      payment of, or in any other term of, all or any of the
                      Obligations of any Foreign Borrower or any other Obligor,
                      or any other extension, compromise or renewal of any
                      Obligation of any Foreign Borrower or any other Obligor;

                             (d)  any reduction, limitation, impairment or
                      termination of any Obligation of any Foreign Borrower or
                      any other Obligor for any reason, including any claim of
                      waiver, release, surrender, alteration or compromise, and
                      shall not be subject to (and the Company hereby waives
                      any right to or claim of) any defense or setoff,
                      counterclaim, recoupment or termination whatsoever by
                      reason of the invalidity, illegality, nongenuineness,
                      irregularity, compromise, unenforceability of, or any
                      other event or occurrence affecting, any Obligation of
                      any Foreign Borrower, any other Obligor or otherwise;

                             (e)  any amendment to, rescission, waiver, or
                      other modification of, or any consent to departure from,
                      any of the other terms of this Agreement or any other
                      Loan Document;

                             (f)  any addition, exchange, release, surrender or
                      non-perfection of any collateral, or any amendment to or
                      waiver or release or addition of, or consent to departure
                      from, any other guaranty, held by any Lender securing any
                      of the Obligations of any Foreign Borrower or any other
                      Obligor; or





                                      155
<PAGE>   164
                             (g)  any other circumstance which might otherwise
                      constitute a defense available to, or a legal or
                      equitable discharge of, any Foreign Borrower, any other
                      Obligor, any surety or any guarantor.

                      SECTION 10.4.  Reinstatement, etc.  The Company agrees
that this Article X shall continue to be effective or be reinstated, as the
case may be, if at any time any payment (in whole or in part) of any of the
Obligations of any Foreign Borrower or any other Obligor is rescinded or must
otherwise be restored by any Lender upon the insolvency, bankruptcy or
reorganization of any Foreign Borrower or any other Obligor or otherwise, all
as though such payment had not been made.

                      SECTION 10.5.  Waiver, etc.  The Company hereby waives
promptness, diligence, notice of acceptance and any other notice with respect
to any of the Obligations of the Foreign Borrowers or any other Obligor and
this Article X and any requirement that the Administrative Agent and any other
Lender protect, secure or perfect or insure any security interest or Lien, or
any property subject thereto, or exhaust any right or take any action against
any Foreign Borrower, any other Obligor or any other Person (including any
other guarantor) or entity or any collateral securing the Obligations of the
Foreign Borrowers or any other Obligor, as the case may be.

                      SECTION 10.6.  Postponement of Subrogation. The Company
agrees that it will not exercise any rights which it may acquire by way of
subrogation under this Article X, by any payment made hereunder or otherwise,
until the prior payment, in full and in cash, of all Obligations of the Foreign
Borrowers and each other Obligor.  Any amount paid to the Company on account of
any such subrogation rights prior to the payment in full of all Obligations of
the Foreign Borrowers and each other Obligor shall be held in trust for the
benefit of the Lenders and shall immediately be paid to the Lenders and
credited and applied against the Obligations of the Foreign Borrowers and each
other Obligor whether matured or unmatured, in accordance with the terms of
this Agreement; provided, however, that if all Obligations of the Foreign
Borrowers and each other Obligor have been paid in full and all Commitments
have been permanently terminated, each Lender agrees that, at the Company's
request, the Lenders will execute and deliver to the Company appropriate
documents (without recourse and without representation or warranty) necessary
to evidence the transfer by subrogation to the Company of an interest in the
Obligations of the Foreign Borrowers and each other Obligor resulting from such
payment by the Company.  In furtherance of the foregoing, for so long as any
Obligations of any Foreign Borrowers or any Commitments remain outstanding, the
Company shall refrain from taking any action or commencing any proceeding
against any Foreign Borrower or any other Obligor (or its successors or
assigns),





                                      156
<PAGE>   165
whether in connection with a bankruptcy proceeding or otherwise to recover any
amounts in respect of payments made under this Article X to any Lender.

                      SECTION 10.7.  Successors, Transferees and Assigns;
Transfers of Notes, etc.  Without limiting the generality of Section 11.11, any
Lender may assign or otherwise transfer (in whole or in part) any Obligation of
any Foreign Borrower held by it to any other Person or entity, and such other
Person or entity shall thereupon become vested with all rights and benefits in
respect thereof granted to such Lender under any Loan Document (including this
Article X) or otherwise, subject, however, to any contrary provisions in such
assignment or transfer, and to the provisions of Section 11.11 and Article IX
of this Agreement.

                            MISCELLANEOUS PROVISIONS

                      SECTION 11.1.  Waivers, Amendments, etc.  The provisions
of this Agreement and of each other Loan Document may from time to time be
amended, modified or waived, if such amendment, modification or waiver is in
writing and consented to by the Company and each Obligor party thereto and by
the Required Lenders; provided, however, that no such amendment, modification
or waiver which would:

                      particular action be taken by all the Lenders or by the
                      Required Lenders shall be effective unless consented to

                      obligations under Article X hereof, or all or
                      substantially all of the collateral security (except in
                      each case as otherwise specifically provided in this
                      Agreement, the Subsidiary Co-Obligation Agreement and
                      Guaranty, a Security Agreement or a Pledge Agreement) or
                      extend any Commitment Termination Date, shall be made
                      without the consent of each Lender adversely affected
                      thereby;

                      of, any scheduled repayment of principal of or interest

                      principal amount of or rate of interest on or fees
                      payable in respect of any Loan or any Reimbursement
                      Obligations (which shall in each case include the
                      conversion of all or any part of the Obligations into
                      equity of any Obligor), shall be made without the consent
                      of the Lender which has made such Loan or, in the case of
                      a Reimbursement Obligation, the Issuer owed, and those
                      Lenders participating in, such Reimbursement Obligation;

                             (d)  affect adversely the interests, rights or
                      obligations of any Agent, any Issuer or the Arranger (in
                      its capacity as Agent, Issuer or Arranger), unless
                      consented to by such Agent, Issuer or Arranger, as the
                      case may be;

                      some later time) of enabling any Borrower to satisfy a
                      condition precedent to the making of a Revolving Loan or
                      the issuance of a Letter of Credit without the consent of
                      Lenders holding at least 51% of the Revolving Loan
                      Commitments; or

                      clause (a)(i) of Section 3.1.1 or clause (b) of Section
                      3.1.2 or effect any amendment, modification or waiver
                      that by its terms adversely affects the rights of Lenders
                      participating in any Tranche differently from those of
                      Lenders participating in other Tranches, without the
                      consent of the holders of at least 51% of the aggregate
                      amount of Loans outstanding under the Tranche or Tranches
                      affected by such amendment, modification or waiver, or,
                      in the case of an amendment, modification or waiver
                      affecting any Tranche or Tranches of Revolving Loan
                      Commitments, the Lenders holding at least 51% of the
                      Revolving Loan Commitments in respect of such Tranche or
                      Tranches.

No failure or delay on the part of any Agent, any Issuer or any Lender in
exercising any power or right under this Agreement or any other Loan Document
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such power or right preclude any other or further exercise thereof or the
exercise of any other power or right.  No notice to or demand on any Borrower
in any case shall entitle it to any notice or demand in similar or other
circumstances.  No waiver or approval by any Agent, any Issuer or any Lender
under this Agreement or any other Loan Document shall, except as may be
otherwise stated in such waiver or approval, be applicable to subsequent
transactions.  No waiver or approval hereunder shall require any similar or
dissimilar waiver or approval thereafter to be granted hereunder.

communications provided to any party hereto under this Agreement or any other
Loan Document shall be in writing or by facsimile and addressed, delivered or

Schedule II hereto or, in the case of a Lender that becomes a party hereto
after the date hereof, as set forth in the Lender Assignment Agreement pursuant
to which such Lender becomes a Lender hereunder or at such other address or
facsimile number as may be designated by such party in a notice to the other
parties.  Any notice, if mailed and properly addressed with postage prepaid or
if properly addressed and sent by pre-paid courier service, shall be deemed
given when received; any notice, if transmitted by facsimile, shall be deemed
given when transmitted (and telephonic confirmation of receipt thereof has been
received).

                      SECTION 11.3.  Payment of Costs and Expenses.  The
Company agrees to pay on demand all reasonable expenses of each of the Agents
(including the reasonable fees and out-of-pocket expenses of a single counsel
to the Agents and of local or foreign counsel, if any, who may be retained by
counsel to the Agents) in connection with

                             (a)  the syndication by the Syndication Agent and
                      the Arranger of the Loans, the negotiation, preparation,

                      other Loan Document, including schedules and exhibits,
                      and any amendments, waivers, consents, supplements or
                      other modifications to this Agreement or any other Loan
                      Document as may from time to time hereafter be required,
                      whether or not the transactions contemplated hereby are
                      consummated;

                             (b)  the filing, recording, refiling or
                      rerecording of each Mortgage, each Pledge Agreement and
                      each Security Agreement and/or any Uniform Commercial
                      Code financing statements relating thereto and all
                      amendments, supplements and modifications to any thereof
                      and any and all other documents or instruments of further
                      assurance required to be filed or recorded or refiled or
                      rerecorded by the terms hereof or of such Mortgage,

Credit or any other Loan Documents.  The Company also agrees to reimburse each
Agent, each Issuer and each Lender upon

as a result of, or arising out of, or relating to

                      whole or in part, directly or indirectly, with the
                      proceeds of any Credit Extension;

                             (b)  the entering into and performance of this
                      Agreement and any other Loan Document by any of the
                      Indemnified Parties (excluding any successful action
                      brought by or on behalf of any Borrower as the result of
                      any failure by any Lender to make any Credit Extension
                      hereunder);

                             (c)  any investigation, litigation or proceeding
                      related to any acquisition or proposed acquisition by the
                      Company or any of its Subsidiaries of all or any portion
                      of the stock or assets of any Person, whether or not such
                      Agent, such Issuer, such Arranger or such Lender is party
                      thereto;

                             (d)  any alleged or actual litigation or
                      proceeding related to any environmental cleanup or
                      noncompliance with or liability under any Environmental
                      Law relating to the use, ownership or operation by the
                      Company or any of its Subsidiaries of any real property
                      or to the release, generation, transportation or

                             (e)  the presence on or under, or the escape,
                      seepage, leakage, spillage, discharge, emission or
                      release from, any real property owned or operated by the
                      Company or any Subsidiary thereof of any Hazardous
                      Material present on or under such property at or prior to
                      the time the Company or such Subsidiary owned or operated
                      such property which gives rise to liability under any
                      Environmental Law (including any losses, liabilities,
                      damages, injuries, costs, expenses or claims asserted or
                      arising under any Environmental Law), regardless of
                      whether caused by, or within the control of, the Company
                      or such Subsidiary,

except for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the relevant Indemnified Party's
gross negligence or willful misconduct or any Hazardous Materials that are
first manufactured, emitted, generated, treated, released, stored or disposed
of on any real property of the Company or any of its Subsidiaries or any
violation of Environmental Law that first occurs on or with respect to any real
property of the Company or any of its Subsidiaries after such real property is
transferred to any Indemnified Person or its successor by foreclosure sale,
deed in lieu of foreclosure, or similar transfer, except to the extent such
manufacture, emission, release, generation, treatment, storage or disposal or
violation is actually caused by Holdco, the Company or any of the Company's
Subsidiaries.  The Company and its permitted successors and assigns hereby
waive, release and agree not to make any claim, or bring any cost recovery
action against, any Agent, any Issuer, the Documentation Agent, the Arranger or
any Lender under CERCLA or any state equivalent, or any similar law now
existing or hereafter enacted, except to the extent arising out of the gross
negligence or willful misconduct of any Indemnified Party.  It is expressly
understood and agreed that to the extent that any Indemnified Party is strictly
liable under any Environmental Laws, the Company's obligation to such
Indemnified Party under this indemnity shall likewise be without regard to
fault on the part of the Company, to the extent permitted under applicable law,
with respect to the violation or condition which results in liability of such
Indemnified Party.  Notwithstanding anything to the contrary herein, each
Agent, each Issuer, the Arranger and each Lender shall be responsible with
respect to any Hazardous Materials that are first manufactured, emitted,
generated, treated, released, stored or disposed of on any real property of the
Company or any of its Subsidiaries or any violation of Environmental Law that
first occurs on or with respect to any such real property after such real
property is transferred to any Agent, Issuer, Arranger or Lender to its
successor by foreclosure sale, deed in lieu of foreclosure, or similar
transfer, except to the extent such manufacture, emission, release, generation,
treatment, storage or disposal or violation is actually caused by Holdco, the
Company or any of the Company's Subsidiaries.  If and to the extent that the
foregoing undertaking may be unenforceable for any reason, the Company hereby
agrees to make the maximum





                                      161
<PAGE>   170
contribution to the payment and satisfaction of each of the Indemnified
Liabilities, which is permissible under applicable law.

                      SECTION 11.5.  Survival.  The obligations of the Company
under Sections 4.3, 4.4, 4.5, 4.6, 11.3 and 11.4, and the obligations of the
Lenders under Sections 4.8 and 9.1, shall in each case survive any termination
of this Agreement, the payment in full of all Obligations and the termination
of all Commitments.  The representations and warranties made by the Company and
each other Obligor in this Agreement and in each other Loan Document shall
survive the execution and delivery of this Agreement and each such other Loan
Document.

                      SECTION 11.6.  Severability.  Any provision of this
Agreement or any other Loan Document which is prohibited or unenforceable in
any jurisdiction shall, as to such provision and such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions of this Agreement or such Loan Document
or affecting the validity or enforceability of such provision in any other
jurisdiction.

                      SECTION 11.7.  Headings.  The various headings of this
Agreement and of each other Loan Document are inserted for convenience only and
shall not affect the meaning or interpretation of this Agreement or such other
Loan Document or any provisions hereof or thereof.

                      SECTION 11.8.  Execution in Counterparts, Effectiveness,
etc.  This Agreement may be executed by the parties hereto in several
counterparts, each of which shall be deemed to be an original and all of which
shall constitute together but one and the same agreement.

                      SECTION 11.9.  Governing Law; Entire Agreement.  THIS
AGREEMENT AND, EXCEPT TO THE EXTENT OTHERWISE EXPRESSLY PROVIDED THEREIN, EACH
OTHER LOAN DOCUMENT SHALL EACH BE DEEMED TO BE A CONTRACT MADE UNDER AND
GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK.  This Agreement and the
other Loan Documents constitute the entire understanding among the parties
hereto with respect to the subject matter hereof and supersede any prior
agreements, written or oral, with respect thereto.  Upon the execution and
delivery of this Agreement by the parties hereto, all obligations and
liabilities of the DLJMB Entities, under or relating or with respect to the
Commitment Letter shall be terminated and of no further force or effect.

                      SECTION 11.10.  Successors and Assigns.  This Agreement
shall be binding upon and shall inure to the benefit of the parties hereto and
their respective successors and assigns; provided, however, that:

<PAGE>   171
                             (a)  no Borrower may assign or transfer its rights
                      or obligations hereunder without the prior written
                      consent of each of the Agents and all Lenders; and

                             (b)  the rights of sale, assignment and transfer
                      of the Lenders are subject to Section 11.11.

                      SECTION 11.11.  Sale and Transfer of Loans and Notes;
Participations in Loans and Notes.  Each Lender may assign, or sell
participations in, its Loans and Commitments to one or more other Persons, on a
non pro rata basis (except as provided below), in accordance with this Section
11.11.

                      SECTION 11.11.1.  Assignments.  Any Lender (the "Assignor
Lender"),

                             (a)  with the written consents of the Company, the
                      Agents and (in the case of any assignment of
                      participations in Letters of Credit or Revolving Loan
                      Commitments) the applicable Issuer (which consents (i)
                      shall not be unreasonably delayed or withheld and (ii) of
                      the Company shall not be required upon the occurrence and
                      during the continuance of any Event of Default), may at
                      any time assign and delegate to one or more commercial
                      banks, funds which are regularly engaged in making,
                      purchasing or investing in loans or securities or other
                      financial institutions, and

                             (b)  with notice to the Company, the Agents, and
                      (in the case of any assignment of participations in
                      Letters of Credit or Revolving Loan Commitments) the
                      applicable Issuer, but without the consent of the
                      Company, the Agents or such Issuer, may assign and
                      delegate to any of its Affiliates or to any other Lender,
                      or to an Approved Fund of any Lender

(each Person described in either of the foregoing clauses as being the Person
to whom such assignment and delegation is to be made, being hereinafter
referred to as an "Assignee Lender"), all or any fraction of such Lender's Term
Loans of any Tranche, Uncommitted Foreign Currency Revolving Loans of any
Tranche or Committed Revolving Loans of such Tranche, participations in Letters
of Credit, Letter of Credit Outstandings with respect thereto and related
Commitments of any Tranche (which assignment and delegation shall be, as among
Revolving Loan Commitments of any Tranche, Committed Revolving Loans of such
Tranche and participations in Letters of Credit of such Tranche, of a constant,
and not a varying, percentage) in a minimum aggregate amount of (i) $5,000,000
(or, in the case of Foreign Currency Loans, the multiple of 100,000 units of
the Currency of such Loans the U.S. Dollar Equivalent of which is nearest to
$5,000,000), or such lesser amount as the





                                      163
<PAGE>   172
Company and the Agents may consent to, or (ii) with respect to the Tranche as
to which such assignment is to occur, the then remaining amount of such
Lender's Term Loans, Uncommitted Foreign Currency Revolving Loans, or Revolving
Loan Commitment and related Committed Revolving Loans and participations in
Letters of Credit, as the case may be; provided, however, that any such
Assignee Lender will comply, if applicable, with the provisions contained in
Section 4.6 and the Borrowers, each other Obligor and the Agents shall be
entitled to continue to deal solely and directly with such Lender in connection
with the interests so assigned and delegated to an Assignee Lender until

                             (i)  written notice of such assignment and
                      delegation, together with payment instructions, addresses
                      and related information with respect to such Assignee
                      Lender, shall have been given to the Company, the
                      applicable Borrower (if other than the Company) and the
                      Agents by such Lender and such Assignee Lender;

                             (ii)  such Assignee Lender shall have executed and
                      delivered to the applicable Borrower and the Agents a
                      Lender Assignment Agreement, accepted by the Agents;

                             (iii)  the processing fees described below shall
                      have been paid; and

                             (iv)  the Administrative Agent shall have
                      registered such assignment and delegation in the Register
                      pursuant to clause (b) of Section 2.9.

From and after the date that the Agents accept such Lender Assignment Agreement
and such assignment and delegation is registered in the Register pursuant to
clause (b) of Section 2.9, (x) the Assignee Lender thereunder shall be deemed
automatically to have become a party hereto and to the extent that rights and
obligations hereunder have been assigned and delegated to such Assignee Lender
in connection with such Lender Assignment Agreement, shall have the rights and
obligations of a Lender hereunder and under the other Loan Documents, and (y)
the Assignor Lender, to the extent that rights and obligations hereunder have
been assigned and delegated by it in connection with such Lender Assignment
Agreement, shall be released from its obligations hereunder and under the other
Loan Documents.  Any Assignor Lender that shall have previously requested and
received any Note or Notes in respect of any Tranche to which any such
assignment applies shall, upon the acceptance by the Administrative Agent of
the applicable Lender Assignment Agreement, mark such Note or Notes "exchanged"
and deliver them to the applicable Borrower (against, if the Assignor Lender
has retained Loans or Commitments with respect to the applicable Tranche and
has requested replacement Notes pursuant to clause (b)(ii) of Section 2.9, its
receipt from the applicable Borrower of replacement Notes in the principal
amount of the Loans and Commitments of the applicable Tranche retained by it).
Such Assignor Lender or





                                      164
<PAGE>   173
such Assignee Lender must also pay a processing fee to the Administrative Agent
upon delivery of any Lender Assignment Agreement in the amount of $3,500,
unless such assignment and delegation is by a Lender to its Affiliate or
Approved Fund or if such assignment and delegation is by a Lender to a Federal
Reserve Bank, as provided below or is otherwise consented to by the
Administrative Agent.  Any attempted assignment and delegation not made in
accordance with this Section 11.11.1 shall be null and void.  Nothing contained
in this Section 11.11.1 shall prevent or prohibit any Lender from pledging its
rights (but not its obligations to make Loans or participate in Letters of
Credit or Letter of Credit Outstandings) under this Agreement and/or its Loans
hereunder to a Federal Reserve Bank in support of borrowings made by such
Lender from such Federal Reserve Bank, and any Lender that is a fund that
invests in bank loans may pledge all or any portion of its rights (but not its
obligations to make Loans or participate in Letters of Credit or Letter of
Credit Outstandings) hereunder to any trustee or any other representative of
holders of obligations owed or securities issued by such fund as security for
such obligations or securities.  In the event that S&P, Moody's or Thompson's
BankWatch (or InsuranceWatch Ratings Service, in the case of Lenders that are
insurance companies (or Best's Insurance Reports, if such insurance company is
not rated by Insurance Watch Ratings Service)) shall, after the date that any
Lender with a Commitment to make Revolving Loans or participate in Letters of
Credit becomes a Lender, downgrade the long-term certificate of deposit rating
or long-term senior unsecured debt rating of such Lender, and the resulting
rating shall be below BBB-, Baa3 or C (or BB, in the case of Lender that is an
insurance company (or B, in the case of an insurance company not rated by
InsuranceWatch Ratings Service)), respectively, then the applicable Issuer or
the Company shall have the right, but not the obligation, upon notice to such
Lender and the Agents, to replace such Lender with an Assignee Lender in
accordance with and subject to the restrictions contained in this Section, and
such Lender hereby agrees to transfer and assign without recourse (in
accordance with and subject to the restrictions contained in this Section) all
its interests, rights and obligations in respect of its Revolving Loan
Commitment under this Agreement to such Assignee Lender; provided, however,
that (i) no such assignment shall conflict with any law, rule, regulation or
order of any governmental authority and (ii) such Assignee Lender shall pay to
such Lender in immediately available funds on the date of such assignment the
principal of and interest and fees (if any) accrued to the date of payment on
the Loans made, and Letters of Credit participated in, by such Lender hereunder
and all other amounts accrued for such Lender's account or owed to it
hereunder.

                      SECTION 11.11.2.  Participations.  Any Lender may at any
time sell to one or more commercial banks or other Persons (each such
commercial bank and other Person being herein called a "Participant")
participating interests in any of the Loans, Commitments,





                                      165
<PAGE>   174
participations in Letters of Credit and Letter of Credit Outstandings or other
interests of such Lender hereunder; provided, however, that

                             (a)  no participation contemplated in this Section
                      shall relieve such Lender from its Commitments or its
                      other obligations hereunder or under any other Loan
                      Document;

                             (b)  such Lender shall remain solely responsible
                      for the performance of its Commitments and such other
                      obligations;

                             (c)  each Borrower and each other Obligor and the
                      Agents shall continue to deal solely and directly with
                      such Lender in connection with such Lender's rights and
                      obligations under this Agreement and each of the other
                      Loan Documents;

                             (d)  no Participant, unless such Participant is
                      itself a Lender, shall be entitled to require such Lender
                      to take or refrain from taking any action hereunder or
                      under any other Loan Document, except that such Lender
                      may agree with any Participant that such Lender will not,
                      without such Participant's consent, agree to (i) any
                      reduction in the interest rate or amount of fees that
                      such Participant is otherwise entitled to, (ii) a
                      decrease in the principal amount, or an extension of the
                      final Stated Maturity Date, of any Loan in which such
                      Participant has purchased a participating interest or
                      (iii) a release of all or substantially all of the
                      collateral security under the Loan Documents or any
                      material Subsidiary Co-Obligor under the Subsidiary
                      Co-Obligation Agreement and Guaranty, if any,  in each
                      case except as otherwise specifically provided in a Loan
                      Document; and

                             (e)  no Borrower shall be required to pay any
                      amount under Sections 4.3, 4.4, 4.5, 4.6, 11.3 and 11.4
                      that is greater than the amount which it would have been
                      required to pay had no participating interest been sold.

The Borrowers acknowledge and agree, subject to clause (e) above, that, to the
fullest extent permitted under applicable law, each Participant, for purposes
of Sections 4.3, 4.4, 4.5, 4.6, 4.8, 4.9, 11.3 and 11.4, shall be considered a
Lender.

                      SECTION 11.12.  Other Transactions.  Nothing contained
herein shall preclude any Agent or any other Lender from engaging in any
transaction, in addition to those contemplated by this Agreement or any other
Loan Document, with any Borrower or any of its Affiliates in which such
Borrower or such Affiliate is not restricted hereby from engaging with any
other Person.

COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR

REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN
INCONVENIENT FORUM.

                      (b)  NOTHING IN THIS SECTION SHALL AFFECT THE RIGHT OF

JURISDICTIONS.

                      (c)  TO THE EXTENT ANY BORROWER HAS OR HEREAFTER MAY

ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION, EXECUTION OR
OTHERWISE) WITH RESPECT TO ITSELF OR TO ITS PROPERTY, EACH BORROWER HEREBY
IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS
AGREEMENT AND EACH OTHER LOAN DOCUMENT EXECUTED OR TO BE EXECUTED BY IT.

                      SECTION 11.14.  Judgment Currency.  (a)  If, for the
purpose of obtaining judgment in any court, it is necessary to convert a sum
due hereunder, under any Note or under any other Loan Document in another
currency into U.S. Dollars or into a Foreign Currency, as the case may be, the
parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which, in accordance with
normal banking procedures, the applicable Secured Party could purchase such
other currency with U.S. Dollars or with such Foreign Currency, as the case may
be, in New York City, at the close of business on the Business Day immediately
preceding the day on which final judgment is given, together with any premiums
and costs of exchange payable in connection with such purchase.

                      (b)  The obligation of each of the Borrowers in respect
of any sum due from it to any Agent, any Lender or any other Secured Party
hereunder, under any Note or under any other Loan Document shall,
notwithstanding any judgment in a currency other than U.S. Dollars or a Foreign
Currency, as the case may be, be discharged only to the extent that on the
Business Day next succeeding receipt by such Agent, such Lender or such other
Secured Party of any sum adjudged to be so due in such other currency, such
Agent, such Lender or such other Secured Party may, in accordance with normal
banking procedures, purchase U.S. Dollars or such Foreign Currency, as the case
may be, with such other currency. If the U.S. Dollars or such Foreign Currency
so purchased are less than the sum originally due to such Agent, such Lender or
such other Secured Party in U.S. Dollars or in such Foreign Currency, each of
the Borrowers agrees, as a separate obligation and notwithstanding any such
judgment, to indemnify such Agent, such Lender or such other Secured Party
against such loss.

                      SECTION 11.15.  Waiver of Jury Trial.  THE AGENTS, THE
ISSUERS, THE LENDERS AND THE BORROWERS HEREBY KNOWINGLY, VOLUNTARILY AND
INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF
ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH,
THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE AGENTS, THE
LENDERS OR ANY BORROWER RELATING THERETO.  EACH

BORROWER ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT
CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER LOAN
DOCUMENT TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL
INDUCEMENT FOR THE AGENTS AND THE LENDERS ENTERING INTO THIS AGREEMENT AND EACH
SUCH OTHER LOAN DOCUMENT.

                      SECTION 11.16.  Confidentiality.  The Agents, the
Issuers, the Arranger and the Lenders shall hold all non-public information
obtained pursuant to or in connection with this Agreement or obtained by them
based on a review of the books and records of the Company or any of its
Subsidiaries in accordance with their customary procedures for handling
confidential information of this nature, but may make disclosure to any of
their examiners, Affiliates, Approved Funds, outside auditors, counsel and
other professional advisors in connection with this Agreement or as reasonably
required by any potential bona fide transferee, participant or assignee, or to
any direct or indirect contractual counterparties in swap agreements or such
contractual counterparties' professional advisors, or in connection with the
exercise of remedies under a Loan Document, or as requested by any governmental
or regulatory agency, or the National Association of Insurance Commissioners,
or representative of any thereof or pursuant to legal process; provided,
however, that

                             (a)  unless specifically prohibited by applicable
                      law or court order, each Agent, each Issuer, the Arranger
                      and each Lender shall promptly notify the Company of any
                      request by any governmental agency or representative
                      thereof (other than any such request in connection with
                      an examination of the financial condition of such Agent,
                      such Issuer, the Arranger and such Lender by such
                      governmental agency) for disclosure of any such
                      non-public information prior to disclosure of such
                      information;

                             (b)  prior to any such disclosure pursuant to this
                      Section 11.16, each Agent, each Issuer, the Arranger and
                      each Lender shall require any such bona fide transferee,
                      participant and assignee receiving a disclosure of
                      non-public information to agree in writing

                                  (i)  to be bound by this Section 11.16; and

                                  (ii)  to require such Person to require any
                             other Person to whom such Person discloses such
                             non-public information to be similarly bound by
                             this Section 11.16; and

                             (c)  except as may be required by an order of a
                      court of competent jurisdiction and to the extent set
                      forth therein, no Lender shall be obligated or required
                      to return any materials furnished by the Company or any
                      of its Subsidiaries.

securities or assets of the Target, or otherwise (each a "Acquisition"), and
(ii) following the closing of the Acquisition, and continuing for a period of
five years thereafter (the "Engagement Period"), with respect to the review and
analysis of financial and structural alternatives available to the Company with
a view to meeting its long term strategic objectives. It is understood and
agreed that the obligations of the Company under this letter agreement
(including without limitation, the indemnification and other obligations of the
Company set forth in Schedule I hereto) shall terminate upon the assumption of
such obligations by the Target upon the consummation of the Acquisition.
Accordingly, following consummation of the Acquisition, all references to the
Company shall be deemed a reference to the Target.

     As discussed, we propose to undertake certain services on your behalf, to
the extent requested by you, which shall consist of the following: (i)
assisting you in evaluating the Target, its operations, its historical
performance and its future prospects; (ii) advising on a proposed purchase
price and form of consideration; (iii) assisting you in structuring the
Acquisition; (iv) negotiating the financial aspects of any Acquisition under
your guidance and (v) assisting you, from time to time, in analyzing the
Company's operations, its historical performance and future prospects.

     As compensation for the services to be provided by DLJ hereunder, the
Company agrees (i) to pay to DLJ (a) a fee of $4,000,000 upon consummation of an
Acquisition (the "Acquisition Fee") and (b) an annual advisory fee of $300,000,
payable quarterly in equal installments of $75,000 on the first business day of
each three month period commencing on the closing of the Acquisition, and (ii)
upon request by DLJ from time to time, to reimburse DLJ promptly for all
out-of-pocket expenses (including the reasonable fees and expenses of counsel)
incurred by DLJ in connection with its engagement hereunder, whether or not an
Acquisition or a Transaction (as defined below) is consummated. As DLJ will be
acting on your behalf, the Company agrees to the

indemnification and other obligations set forth in Schedule I attached hereto,
which Schedule is an integral part hereof.

     The Acquisition Fee shall be in an amount equal to $4,000,000 and shall be
payable in cash promptly upon consummation of the Acquisition. For purposes
of this Agreement, an Acquisition shall be deemed to have been consummated
upon the earliest of any of the following events to occur: (a) the acquisition
by the Company or any of its affiliates of at least fifty one percent (51.0%)
of the outstanding equity securities of the Target, calculated on a
fully-diluted basis; (b) a merger or consolidation of the Target with the
Company or an affiliate of the Company; (c) the acquisition by the Company or
any of its affiliates of assets of the Target representing at least fifty one
percent (51.0%) of the Target's book value or (d) in the case of any other
Acquisition, the consummation thereof.

     In the event an Acquisition is not consummated and the Company receives
cash or assets from the Target (such cash or assets hereinafter referred to as
the "Break-up Fee"), then the Company shall pay to DLJ in cash, promptly upon
the Company's receipt of such Break-up Fee, an amount equal to the lesser of
(x) $2,000,000 or (y) fifteen percent (15%) of such Break-up Fee received (the
"DLJ Participation").

     In connection with any debt or equity financing (other than bank
financing) by the Company (i) the proceeds of which are used to finance all or
a portion of the Acquisition or (ii) which is effected at any time within 12
months following consummation of the Acquisition, DLJ shall have the right but
not the obligation to act as exclusive private placement agent, lead initial
purchaser or sole managing underwriter to the Company, provided that the fees
of DLJ for such services shall be competitive with those customarily charged by
DLJ and other investment banks in similar transactions. In connection with such
financings, the Company shall take such action as is necessary or desirable to
facilitate the public or private sale of such securities, including the
preparation of any documents required to be filed with the Securities and
Exchange Commission and shall enter into a private placement agreement,
purchase agreement or underwriting agreement with DLJ which shall contain
normal and customary provisions for such agreements in which DLJ acts as
placement agent, initial purchaser or managing underwriter, as the case may be.

     As further compensation, the Company agrees that in the event the Company
determines to pursue any Transaction (as hereinafter defined) during the
Engagement Period, DLJ shall have the right to act as the Company's exclusive
financial advisor, sole placement agent, sole initial purchaser, sole managing
underwriter or sole dealer-manager, as the case may be, with respect to each
such Transaction.

     For purposes of this letter, the term "Transaction" shall specifically
exclude the Acquisition and shall include each of the following: (i) the sale,
merger, consolidation or any other business combination, in one or a series of
transactions, involving any portion of the business, securities or assets of
the Company; (ii) the acquisition (and any related matters such as financings,
divestitures, etc.), in one or a series of transactions, of all or a portion of
the business, securities or assets of another entity or person; (iii) any
recapitalization, refinancing, repurchase or restructuring of the Company's
equity or debt securities or indebtedness or any amendments or modifications to
the Company's debt securities or indentures whether or not in connection
therewith, involving, by or on behalf of the Company, an offer to purchase or
exchange for cash, property, securities, indebtedness or other consideration,
or a solicitation of consents, waivers of authorizations with respect thereto;
(iv) any spin-off, split-off or other extraordinary dividend of cash,
securities or other assets to

stockholders of the Company: or (v) any sale of securities of the Company
effected pursuant to a private sale or an underwritten public offering.

     If the Company determines to pursue any such Transaction, DLJ and the
Company will enter into an agreement appropriate to the circumstances,
containing provisions for, among other things, compensation, indemnification,
contribution and representations and warranties, which are usual and customary
for similar agreements entered into by DLJ or other investment bankers of
international standing acting in similar transactions. DLJ shall have no
obligation to act as placement agent, initial purchaser, underwriter or dealer
manager to the Company or to place or purchase any securities of the Company,
except to the extent that such obligations arise out of a placement agent
agreement, purchase agreement, underwriting agreement or dealer-manager
agreement, as the case may be, with respect to a particular Transaction executed
and delivered by both DLJ and the Company.

     The Company shall make available to DLJ all financial and other information
concerning its business and operations that DLJ reasonably requests as well as
any other information relating to the Acquisition and any Transaction prepared
by the Company or any of its other advisors. In performing its services
hereunder, DLJ shall be entitled to rely without investigation upon all
information that is available from public sources as well as all other
information supplied to it by or on behalf of the Company or its advisors or the
Target or its advisors and shall not in any respect be responsible for the
accuracy or completeness of, or have any obligation to verify, the same or to
conduct any appraisal of any of the Company's or the Target's assets or
liabilities. To the extent consistent with legal requirements, all information
given to DLJ by the Company, unless publicly available or otherwise available to
DLJ without restriction or breach of any confidentiality agreement, will be held
by DLJ in confidence and will not be disclosed to anyone other than DLJ's agents
and advisors without the Company's prior approval or used for any purpose other
than those referred to in this Agreement.

     Any advice, written or oral, provided by DLJ pursuant to this Agreement
will be treated by the Company as confidential, will be solely for the
information and assistance of the Company in connection with its consideration
of the Acquisition or a Transaction and will not be reproduced, summarized,
described or referred to, or furnished to any other party or used for any other
purpose, except in each case with our prior written consent.

     The Company acknowledges and agrees that DLJ has been retained solely to
provide the advice or services set forth in this Agreement. DLJ shall act as an
independent contractor, and any duties of DLJ arising out of its engagement
hereunder shall be owed solely to the Company.

     This Agreement may be terminated by DLJ at any time or by the Company upon
expiration of the Engagement Period upon receipt of written notice to that
effect by the other party. Upon any termination or expiration of this Agreement,
DLJ will be entitled to prompt payment of all fees accrued prior to such
termination or expiration and reimbursement of all out-of-pocket expenses as
described above. The indemnity and other provisions contained in Schedule I will
also remain operative and in full force and effect regardless of any termination
or expiration of this Agreement.

     In addition, if at any time prior to 12 months after termination or
expiration of this Agreement an Acquisition is consummated or the Company is
entitled to receive a Break-up Fee, DLJ will be entitled to payment in full of
the Acquisition Fee or the DLJ Participation, as the case may be. Further, if at
any time prior to 12 months after the termination or expiration of this

Agreement, a Transaction is consummated with respect to which DLJ was not
invited by the Company to act as financial advisor, placement agent, initial
purchaser, underwriter or dealer-manager, as the case may be, the Company
shall, promptly upon consummation of each such Transaction pay DLJ a cash fee
in an amount equal to the usual and customary fees which would have been to DLJ
by the Company if DLJ had acted in such capacity, with regard to the
consummated Transaction(s).

     It is understood that if the Company completes a transaction in lieu of
the Acquisition or any Transaction, either during the Engagement Period or at
any time prior to 12 months after termination by the Company or expiration of
this Agreement, for which DLJ is entitled to compensation pursuant to this
Agreement, DLJ and the Company will in good faith mutually agree upon
acceptable compensation for DLJ taking into account, among other things, the
results obtained and the custom and practice of investment bankers of
international standing acting in similar transactions.

     The Company further agrees that it will not enter into any transaction
referred to in either of the two preceding paragraphs unless, prior to or
simultaneously with such transaction, adequate provision is made with respect
to the payment of compensation to DLJ as contemplated by such paragraphs.

     This Agreement shall be binding upon and inure to the benefit of the
Company, DLJ, each Indemnified Person (as defined in Schedule I) and their
respective successors and assigns.

     This Agreement shall be governed by, and construed and enforced in
accordance with, the laws of the State of New York.

     The Company irrevocably and unconditionally submits to the exclusive
jurisdiction of any State or Federal court sitting in New York city over any
suit, action or proceeding arising out of or relating to this Agreement
(including Schedule I). The Company hereby agrees that service of any process,
summons, notice or document by U.S. registered mail addressed to the Company
shall be effective service of process for any action, suit or proceeding brought
in any such court. The Company irrevocably and unconditionally waives any
objection to the laying of venue of any such suit, action or proceeding
brought in any such court and any claim that any such suit, action or
proceeding brought in such a court has been brought in an inconvenient forum.
The Company agrees that a final judgment in any such suit, action or proceeding
brought in any such court shall be conclusive and binding upon the Company and
may be enforced in any other courts to whose jurisdiction the Company is or may
be subject, by suit upon such judgment.

     If any term, provision, covenant or restriction contained in this
Agreement, including Schedule I, is held by a court of competent jurisdiction
or other authority to be invalid, void, unenforceable or against its regulatory
policy, the remainder of the terms, provisions, covenants and restrictions
contained in this Agreement shall remain in full force and effect and shall in
no way be affected, impaired or invalidated.

                                   SCHEDULE I

     This Schedule I is a part of and is incorporated into that certain letter
agreement (together, the "Agreement") dated January 16, 1998 by and between DLJ
Merchant Banking II, Inc. (the "Company") and Donaldson, Lufkin & Jenrette
Securities Corporation ("DLJ").

     The Company will indemnify and hold harmless DLJ and its affiliates, and
the respective directors, officers, agents and employees of DLJ and its
affiliates (DLJ and each such entity or person, an "Indemnified Person") from
and against any losses, claims, damages, judgments, assessments, costs and
other liabilities (collectively "Liabilities"), and will reimburse each
Indemnified Person for all fees and expenses (including the reasonable fees and
expenses of counsel) (collectively "Expenses") as they are incurred in
investigating, preparing, pursuing, or defending any claim, action, proceeding
or investigation, whether or not in connection with pending or threatened
litigation or arbitration and whether or not any Indemnified Person is a party
(collectively, "Actions"), arising out of or in connection with advice or
services rendered or to be rendered by any Indemnified Person pursuant to this
Agreement, the transactions contemplated hereby or any Indemnified Person's
actions or inactions in connection with any such advice, services or
transactions; provided that the Company will not be responsible for any
Liabilities or Expenses of any Indemnified Person that are determined by a
judgment of a court of competent jurisdiction which is no longer subject to
appeal or further review to have resulted solely from such Indemnified Person's
gross negligence or willful misconduct in connection with any of the advice,
actions, inactions or services referred to above; it being understood and
agreed that for purposes of this Schedule I, the term "Indemnified Person"
shall specifically exclude the Company.  The Company also agrees to reimburse
each Indemnified Person for all Expenses as they are incurred in connection
with enforcing such Indemnified Person's rights under this Agreement
(including, without limitation, its rights under this Schedule I).

     Upon receipt by an Indemnified Person of actual notice of an Action
against such Indemnified Person with respect to which indemnity may be sought
under this Agreement, such Indemnified Person shall promptly notify the Company
in writing; provided that failure so to notify the Company shall not relieve
the Company from any liability which the Company may have on account of this
indemnity or otherwise, except to the extent the Company shall have been
materially prejudiced by such failure.  The Company shall, if requested by DLJ,
assume the defense of any such Action including the employment of counsel
reasonably satisfactory to DLJ.  Any Indemnified Person shall have the right to
employ separate counsel in any such action and participate in the defense
thereof but the fees and expenses of such counsel shall be at the expense of
such Indemnified Person, unless: (i) the Company has failed promptly to assume
the defense and employ counsel or (ii) the named parties to any such Action
(including any impleaded parties) include such Indemnified Person and the
Company, and such Indemnified Person shall have been advised by counsel that
there may be one or more legal defenses available to it which are different
from or in addition to those available to the Company; provided that the
Company shall not in such event be responsible hereunder for the fees and
expenses of more than one firm of separate counsel in connection with any
Action in the same jurisdiction, in addition to any local counsel.  The Company
shall not be liable for any settlement of any Action effected without its
written consent.  In addition, the Company will not, without prior written
consent of DLJ, settle, compromise or consent to the entry of any judgment in
or otherwise seek to terminate any pending or threatened Action in respect
<PAGE>   7
of which indemnification or contribution may be sought hereunder (whether or
not any Indemnified Person is a party thereto) unless such settlement,
compromise, consent or termination includes an unconditional release of each
Indemnified Person from all Liabilities arising out of such Action.

     In the event the foregoing indemnity is unavailable to an Indemnified
Person other than in accordance with this Agreement, the Company shall
contribute to the Liabilities and Expenses paid or payable by such Indemnified
Person in such proportion as is appropriate to reflect (i) the relative
benefits to the Company and its shareholders, on the one hand, and to DLJ, on
the other hand, of the matters contemplated by this Agreement or (ii) if the
allocation provided by the immediately preceding clause is not permitted by the
applicable law, not only such relative benefits but also the relative fault of
the Company, on the one hand, and DLJ, on the other hand, in connection with
the matters as to which such Liabilities or Expenses relate, as well as any
other relevant equitable considerations; provided that in no event shall the
Company contribute less than the amount necessary to ensure that all
Indemnified Persons, in the aggregate, are not liable for any Liabilities and
Expenses in excess of the amount of fees actually received by DLJ pursuant to
this Agreement. For purposes of this paragraph, the relative benefits to the
Company and its shareholders, on the one hand, and to DLJ, on the other hand,
of the matters contemplated by this Agreement shall be deemed to be in the same
proportion as (a) the total value paid or contemplated to be paid or received
or contemplated to be received by the Company or the Company's shareholders, as
the case may be, in the transaction or transactions that are within the scope
of this Agreement, whether or not any such transaction is consummated, bears to
(b) the fees paid or to be paid to DLJ under this Agreement.

     The Company also agrees that no Indemnified Person shall have any
liability (whether direct or indirect, in contract or tort or otherwise) to the
Company for or in connection with advice or services rendered or to be rendered
by any Indemnified Person pursuant to this Agreement, the transactions
contemplated hereby or any Indemnified Person's actions or inactions in
connection with any such advice, services or transactions except for Liabilities
(and related Expenses) of the Company that are determined by a judgment of a
court of competent jurisdiction which is no longer subject to appeal or further
review to have resulted solely from such Indemnified Person's gross negligence
or willful misconduct in connection with any such advice, actions, inactions or
services.

     The reimbursement, indemnity and contribution obligations of the Company
set forth herein shall apply to any modification of this Agreement and shall
remain in full force and effect regardless of any termination of, or the
completion of any Indemnified Person's services under or in connection with,
this Agreement.
