                               6% NOTES DUE 2005
                      AND 2,100,840 SHARES OF COMMON STOCK
                        ISSUABLE UPON CONVERSION THEREOF
                            ------------------------
 
     This prospectus (the "Prospectus") relates to the offer and sale from time
to time by the holders named herein or by their transferees, pledgees, donees or
successors (collectively, the "Selling Security Holders") of up to $85,000,000
aggregate principal amount of 6% Convertible Notes due 2005 (the "Notes") of
Sabratek Corporation (the "Company" or "Sabratek") and the shares of Common
Stock of the Company into which the Notes are convertible (the "Shares" and,
together with the Notes, the "Securities"). The Notes were acquired from the
Company by Salomon Smith Barney as the Initial Purchaser in April 1998 in
connection with a private offering.
 
     The Notes are convertible at the option of the holder into shares of Common
Stock of the Company, at any time prior to redemption or maturity, at a
conversion price of $40.46 per share, representing in the aggregate 2,100,840
shares, subject to adjustment under certain circumstances. Interest on the Notes
is payable semi-annually in arrears on April 15 and October 15 of each year,
commencing on October 15, 1998.
 
     The Notes do not provide for a sinking fund. The Notes are unsecured
obligations of the Company and rank pari passu with all existing and future
unsecured Indebtedness (as such term is defined below) and other liabilities of
the Company but subordinated to all existing and future secured obligations of
the Company and to all existing and future Indebtedness of the Company and any
liabilities of any subsidiaries of the Company. The Notes will mature on April
15, 2005, and may be redeemed, at the option of the Company, in whole or in
part, at any time on or after April 19, 2001, at the redemption prices set forth
herein plus accrued interest. Each holder of Notes will have the right to cause
the Company to repurchase all of such holder's Notes, payable in cash at a
purchase price equal to 100% of the principal amount thereof, plus accrued
interest or, at the Company's option, in Common Stock, in the event the Common
Stock is no longer publicly traded or in certain circumstances involving a
Change of Control (as defined in the Indenture).
 
     The Notes and the Shares are being registered to permit public secondary
trading of the Notes and, upon conversion, the underlying Shares, by the holders
thereof from time to time after the date of this Prospectus. The Securities may
be offered by the Selling Security Holders from time to time in transactions
(which may include block transactions in the case of the Shares) on any exchange
or market on which such securities are listed or quoted, as applicable, in
negotiated transactions, through a combination of such methods of sale, or
otherwise, at sale, at prices related to prevailing market prices, or at
negotiated prices. The Selling Security Holders may effect such transactions by
selling the Notes or Shares directly to or through broker-dealers, who may
receive compensation in the form of discounts, concessions or commissions from
the Selling Security Holders and/or the purchasers of the Notes or Shares for
whom such broker-dealers may act as agents or to whom they may sell as
principals, or both (which compensation as to a particular broker-dealer might
be in excess of customary commissions). The Company will not receive any of the
proceeds from the sale of the Notes or Shares by the Selling Security Holders.
The Company has agreed to pay all expenses incident to the offer and sale of the
Securities offered by the Selling Security Holders hereby, except that the
Selling Security Holders will pay all underwriting discounts and selling
commissions, if any. See "Plan of Distribution".
 
     The Notes have been designated for trading on the Private Offerings,
Resales and Trading through Automated Linkages ("PORTAL") Market. Notes sold
pursuant to this Prospectus are not expected to remain eligible for trading on
the PORTAL Market. The Common Stock is traded in the over-the-counter market and
is quoted on the National Association of Securities Dealers Automated
Quotation -- National Market System ("NASDAQ -- NMS"), under the symbol SBTK. On
June 11, 1998, the last sale price for the Common Stock, as reported on
NASDAQ -- NMS, was $24 1/8 per share.
 
     PROSPECTIVE INVESTORS SHOULD CONSIDER AND REVIEW THE INFORMATION UNDER THE
CAPTION "RISK FACTORS" COMMENCING ON PAGE 5 PRIOR TO AN INVESTMENT IN THE SHARES
OFFERED HEREBY.
                            ------------------------
 
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.

                                  THE COMPANY
 
     Sabratek Corporation (the "Company" or "Sabratek") develops, produces and
markets technologically-advanced, user-friendly and cost-effective therapeutic
and diagnostic medical systems designed specifically to meet the unique needs of
the alternate-site health care market. The Company's multi-therapy infusion and
other systems incorporate advanced communications technology which is designed
to reduce provider operating costs while maintaining the integrity and quality
of care. Sabratek's proprietary health care information system provides remote
programming as well as real-time diagnostic and therapeutic data capture
capabilities, allowing caregivers to monitor patient compliance more effectively
and allowing providers to develop outcome analyses and optimal clinical
protocols. The Company has designed its integrated hardware and software system
to permit providers of infusion therapy to achieve cost-effective movement of
patients along the continuum of alternate-site health care settings. The Company
intends to expand its product line beyond infusion therapy to become a leading
developer and marketer of a variety of interactive therapeutic and diagnostic
medical systems for the delivery of high-quality, cost-effective health care in
alternate sites. The Company believes that its current and future products and
related software will facilitate the ability of alternate-site providers to
create a "virtual" hospital room, thereby affording the delivery of a wide range
of care previously provided primarily in an acute-care setting. Substantially
all of the Company's revenues have historically been derived from the sale of
its multi-therapy infusion pumps and related disposable supplies. Since August,
1996, the Company has commercially introduced its proprietary medical software
system ("MediVIEW"), its proprietary infusion pump testing device (the
"PumpMaster") and prepackaged injectable prescription products and pre-filled
I.V. tubing flush syringes which further the Company's strategy of creating a
virtual hospital room.
 
     Sabratek's strategy focuses primarily on the alternate-site health care
market, which it believes will continue to experience significant growth as
managed care payors continue to move patients to the lowest-cost care setting.
Such growth may be attributed to increasing cost-containment pressures, along
with advances in medical technology, that have transitioned the delivery of
health care away from the traditional acute-care setting to more cost-effective
sites. The alternate-site market includes, among other things, the provision of
infusion services in various settings, including the patient's residence,
sub-acute care facilities, nursing homes, outpatient clinics, dialysis centers
and hospice facilities. According to POV, Incorporated, an industry tracking and
consulting firm, the infusion therapy segment of this market is expected to grow
in revenue from $3.2 billion in 1992 to $7.9 billion in 1997, representing an
average annual compounded growth rate of approximately 20%.
 
     The Company believes that for alternate-site health care providers, the
management of costly resources such as nursing staff and infusion equipment
inventories is critical to their operating viability. The Company's strategic
response to the need to achieve cost-effective movement of patients along the
continuum of alternate-site care has been to develop the Seamless Delivery
System which integrates stationary and ambulatory multi-therapy infusion pumps,
disposable supplies, a proprietary interactive software system and a proprietary
infusion pump testing device. Sabratek's Seamless Delivery System maximizes the
similarities in operating features and range of therapeutic applications of the
Company's stationary and ambulatory infusion devices, thereby reducing the
costly time requirements of training and infusion administration as well as
minimizing equipment inventories. The Company's interactive software system
augments the utilization of Sabratek's infusion pumps and allows providers to
program therapies and monitor compliance on a real-time basis from a remote
location. The Company's portable, automatic infusion pump testing device enables
providers to perform on-site diagnostic tests on Sabratek's infusion pumps and
thereby reduces costs by eliminating the traditional reliance on third-party
testing services and in-house biomedical engineering capabilities. The Company
believes that competing infusion therapy products do not meet the diverse needs
of payors, alternate-site health care providers and their patients within the
managed care environment to the same extent as the Company's Seamless Delivery
System.
 
     In 1992, the Company commercially launched its multi-therapy stationary
infusion device (the "3030 Stationary Pump"), and in 1995 introduced its
multi-therapy ambulatory infusion device (the "6060 Ambulatory Pump"). In
addition, the Company markets a comprehensive line of related disposable tubing
sets. Both the 3030 Stationary Pump and the 6060 Ambulatory Pump have received
510(k) clearance from
                                        3

the Food and Drug Administration (the "FDA"). In 1996, the Company began
marketing MediVIEW and the PumpMaster. The Company currently markets its
products domestically to national, regional and local alternate-site and
acute-care providers through a dedicated sales force composed of 24 direct sales
professionals, 9 clinical support staff members and 2 full-time sales
consultants who work closely with a network of specialized alternate-site
medical products distributors. The Company also markets its products
internationally through distributors in Europe, Asia, Africa, South America and
the Middle East.
 
     In February, 1997, the Company began producing and marketing prepackaged
injectable prescription products and pre-filled I.V. tubing flush syringes
through the operation of Rocap, Inc. The Rocap product line expands the scope of
the Company's product offering to alternative-site and acute-care providers.
 
     In July, 1997, the Company entered into a licensing agreement with Unitron
Medical Communications, Inc. ("Unitron"), a privately held company which has
developed MOON, a proprietary clinical patient information management network.
Unitron is in the process of deploying the MOON network on a national basis.
MOON provides for continuous, real-time monitoring and reporting of clinical
patient information from any site, including the patient's home. Unlike in an
acute care setting, patients in the alternate-site health care environment are
often not in close physical proximity to their health care providers. As a
result, patient information from the point of care is often communicated to the
health care provider in a less timely and complete manner. In addition,
physicians generally are less able to monitor the patient, including compliance
with prescribed therapy and the management of care delivered by other providers.
The goal of MOON is to enable health care providers to more effectively treat
higher acuity patients in an alternate-site health care setting by maintaining
the provider's ability to direct the patient's care, monitor compliance with
prescribed therapies and have access to timely clinical information. MOON is
designed to allow the provider to reduce the need for on-site visits without
compromising the quality of patient care. MOON allows caregivers to input
patient information into a data repository which is immediately available to
other providers, including physicians. The Company anticipates that its
interactive medical devices will, in the future, transit patient information
directly to MOON without human interaction. The immediate availability of
patient information is a significant improvement over the current paper-based
reporting system which often lags two or more weeks behind the initial
collection of such information. MOON allows providers immediate access to
patient information. Additionally, the individual health care provider tracking
information is useful to payors and the agencies/companies managing the
provider. The Company intends to combine its proprietary MediVIEW medical device
management and telemedicine software with Unitron's clinical patient information
management network. The Company believes that this combination is likely to
accelerate the realization of the data management aspects of the virtual
hospital room.
 
     In August, 1997, the Company entered into a supply and distribution
agreement with GDS Technology, Inc. ("GDS"), a privately held medical device
company. GDS manufactures bulk and specific enzymes and reagents for the
diagnostic testing industry, as well as Stat-Site, a unique test system for the
point of care market. GDS has 510(k) approval for its Stat-Site device and a
limited number of tests. The Stat-Site system provides immediate availability of
certain critical information which can be used for diagnosis or monitoring the
efficacy of a patient's drug therapy. For certain disease states, this
information is important to determine the regimen of care. The Company intends
to integrate the GDS Stat-Site system and the data that it provides with its
other medical devices as part of the virtual hospital room in order to enhance
its capabilities to serve the alternate-site health care market.
 
     The Company plans to continue to develop and market interactive therapeutic
and diagnostic medical systems designed to improve the delivery of high-quality,
cost-effective health care at alternate sites. The Company intends to achieve
its goal by continuing to: (i) offer advanced medical products and related
software systems that maximize the cost-effective provision of alternate-site
health care, (ii) offer an integrated system of therapeutic and diagnostic
information-based medical products supported by the Company's proprietary health
care information system platform, (iii) create a proprietary outcomes database
through the Company's products and information system platform and (iv) pursue
strategic partnerships and acquisitions which further the realization of the
virtual hospital room and expand the Company's product offering.

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, the following
should be considered carefully by potential purchasers of the Notes or the
Shares. Prospective purchasers are cautioned that statements in this Prospectus
(including the documents incorporated by reference herein) that are not
descriptions of historical facts should be considered as forward-looking
statements. Such statements reflect management's current views, are based on
many assumptions and are subject to risks and uncertainties. Actual results
could differ materially from those currently anticipated due to a number of
factors, including but not limited to those discussed below.
 
HISTORY OF LOSSES
 
     The Company was formed in 1989, introduced its first product in 1992, has
incurred operating and net losses of approximately $3.6 million, $6.0 million
and $858,000 for the years 1994, 1995 and 1996, respectively, and, at December
31, 1997, had an accumulated deficit of $7.1 million. For the year ended
December 31, 1997 the Company reported net income of approximately $7.2 million.
The Company's losses resulted primarily from expenditures relating to research
and development, product engineering, obtaining FDA clearance for its products,
development of its initial sales and marketing organization, and establishment
of manufacturing capability. Although the Company has experienced revenue growth
in recent periods and has operated at a profit since the third quarter of 1996,
such recent growth and profitability may not be sustainable and may not be
indicative of future results. The Company's ability to increase sales and
generate profits will depend on numerous factors, and there can be no assurance
that the Company's revenues will continue to grow or that the Company will
remain profitable.
 
DEPENDENCE ON PRINCIPAL PRODUCT LINE AND NEW PRODUCT DEVELOPMENT
 
     The Company currently derives substantially all of its revenues from the
sale of its multi-therapy infusion pumps and related disposable supplies and
expects that revenues from these products will continue to account for a
significant portion of the Company's revenues in the future. Although the
commercial introduction of MediVIEW and PumpMaster along with the acquisition of
Rocap reduce the Company's reliance on its principal product line, future
declines in the demand for the Company's infusion pumps and related disposable
supplies, whether due to increased competition, technological changes, or other
factors, could have a material adverse effect on the Company's business,
financial condition and results of operations. The Company's execution of its
business strategy and its future financial performance will depend in large part
on the Company's ability to meet the increasingly sophisticated needs of its
customers through the timely development and successful introduction or
acquisition of new infusion therapy products, enhanced versions of existing
products, and new complementary products. The success of new or enhanced
products is subject to certain risks inherent in the development of products and
materials based upon new technologies. These risks include the possibilities
that (i) certain of the products developed may require and fail to receive
regulatory clearance or approval, (ii) the products may be difficult to
manufacture on a commercial scale or may be uneconomical to manufacture or
market, (iii) the proprietary rights of third parties may preclude the Company
from marketing such products, (iv) the Company's competitors may market
superior, more cost-effective or equivalent products and may do so on a more
timely basis, (v) errors and malfunctions may be found in products after their
commercial introduction and may not be corrected in a timely manner, and (vi)
customers may not accept or use the products. The Company has historically
expended a significant amount on product development and believes that
significant continuing product development efforts will be required to sustain
the Company's growth. There can be no assurance that the market will continue to
accept the Company's existing products, or that product enhancements or new
products will be developed in a timely and cost-effective manner, meet the needs
and requirements of alternate-site health care providers or achieve market
acceptance. In addition, the Company may be unable to acquire additional
products and technologies.
 
HIGHLY COMPETITIVE MARKETS; TECHNOLOGICAL RISK
 
     The medical products industry in general and the infusion therapy products
industry in particular are characterized by intense competition. Large
competitors, such as Abbott Laboratories; Alaris Medical, Inc.;
                                        5
<PAGE>   9
 
Baxter International Inc.; I-Flow Corp.; McGaw, Inc., an indirect subsidiary of
B. Braun Melsungen AG; and SIMS Deltec, Inc., a subsidiary of Smiths Industries,
PLC ("SIMS Deltec"), among others, have significant market shares and installed
bases of products in the infusion pump and related disposable supplies industry.
Many of the Company's competitors have substantially greater capital resources,
research and development staffs, regulatory experience, sales and marketing
capabilities, manufacturing facilities and broader product offerings than the
Company. The Company expects that these competitors will continue to compete
aggressively with tactics such as offering volume discounts based on "bundled"
purchases of a broader range of medical equipment and supplies, a tactic that
the Company can currently only pursue on a more limited basis. There can be no
assurance that such competition will not adversely affect the Company's results
of operations or its ability to maintain or increase sales and market share. As
a consequence of the foregoing, the Company may not be able to successfully
execute its business strategies.
 
     The market for infusion therapy products is affected by continuing
improvements and enhancements in technology. There can be no assurance that the
Company's competitors or potential competitors will not succeed in developing or
marketing products that provide more desirable characteristics, or are more
effective or less expensive than those developed or marketed by the Company. In
addition, technological advances in drug delivery systems, the development of
therapies that can be administered by methods other than infusion therapy, and
the development of new medical treatments that cure certain complex diseases or
reduce the need for infusion therapy could adversely impact the Company's
business.
 
ABILITY TO SERVICE DEBT; FINANCIAL CONDITION
 
     The funds generated by existing operations may not be at levels sufficient
to enable the Company to meet its debt service obligations on the Notes (which
initially will be $ 5.1 million annual and other fixed charges.) If the Company
fails to achieve and maintain sufficient cash flows from operations, its ability
to make payments required with respect to the Notes, including interest and
principal payments, will depend on its ability to secure funds from other
sources. There can be no assurance that cash flows from future operations of the
Company (including earnings from the interim investment of a portion of the net
proceeds from the offering), together with funds from such other sources, if
any, will be sufficient to enable the Company to meet its debt service
obligations.
 
UNCERTAIN PROTECTION OF INTELLECTUAL PROPERTY
 
     There can be no assurance that the common law, statutory and contractual
rights on which the Company relies to protect its intellectual property and
confidential and proprietary information will provide it with meaningful
protection. Third parties may independently develop products, techniques or
information which are substantially equivalent to the products, techniques and
information which the Company considers proprietary. In addition, proprietary
information regarding the Company could be disclosed in a manner against which
the Company has no meaningful remedy.
 
     Disputes regarding the Company's intellectual property could force the
Company into expensive and protracted litigation or costly agreements with third
parties. An adverse determination in a judicial or administrative proceeding or
failure to reach an agreement with a third party regarding intellectual property
rights could prevent the Company from manufacturing and selling certain of its
products, which could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
PENDING LITIGATION
 
     On February 5, 1997, SIMS Deltec filed a complaint in the United States
District Court for the District of Minnesota alleging that Sabratek's
manufacture, use and/or sale of the MediVIEW software in conjunction with its
infusion pumps infringes on a patent entitled "Systems and Methods of
Communicating with Ambulatory Medical Devices Such as Drug Delivery Devices"
previously issued to SIMS Deltec. Subsequently, SIMS Deltec filed other
pleadings that raised additional claims against Sabratek and three of its
employees including trade secret misappropriation, unfair competition and
interference with SIMS Deltec's customers. SIMS Deltec seeks injunctive relief,
unspecified monetary damages and costs. In addition, SIMS
 
                                        6
<PAGE>   10
 
Deltec filed for a preliminary injunction against Sabratek seeking to prevent on
a preliminary basis Sabratek's manufacture and sale of the MediVIEW system. On
August 4, 1997, the District Court denied the motion for preliminary injunction.
The Company and the individual defendants intend to vigorously defend against
the allegations made by SIMS Deltec. Protracted litigation or an adverse outcome
in this matter could have a material adverse impact on the Company's business,
financial condition and results of operations.
 
     In addition, Sabratek has filed a complaint against SIMS Deltec in the
United States District Court for the Northern District of Illinois alleging that
SIMS Deltec employees have made misstatements about Sabratek's products.
Sabratek has stated claims under the Federal Lanham Act to stop SIMS Deltec's
improper disparagement and has requested preliminary and permanent injunctive
relief, monetary damages and costs.
 
LIMITED SALES AND MARKETING EXPERIENCE
 
     The Company's sales and marketing staff will require additional personnel
in the future. There can be no assurance that the Company will be able to
continue to successfully expand its sales and marketing staff, that such an
expanded sales and marketing staff will be cost-effective, or that the Company's
increased direct sales and marketing efforts will be successful. The Company
also sells its products through domestic and international distributors of
medical products. There can be no assurance that the Company or its distributors
will be successful in marketing or selling the Company's products.
 
LIMITED ASSEMBLY/MANUFACTURING EXPERIENCE
 
     Most of the Company's products are currently assembled/manufactured by the
Company at its facilities. To be successful, the Company must
assemble/manufacture its products in compliance with regulatory requirements, in
sufficient quantities and on a timely basis, while maintaining product quality
and acceptable assembly/manufacturing costs. There can be no assurance that the
Company will be able to continue to assemble/manufacture products in large
commercial quantities on a timely basis and at an acceptable cost. If the
Company becomes unable to assemble/manufacture its products at its facility in a
timely and efficient manner, the Company's ability to supply product to its
distributors and direct customers may be adversely affected until such time as
the Company is able to establish alternative assembly/manufacture arrangements.
 
INTERRUPTION IN SOURCES OF SUPPLY
 
     The Company could face problems in supplying its equipment and disposable
products to distributors and customers if its primary sources of supply were
interrupted and it faced delays in activating its secondary sources of supply.
Any such interruption or delays could have an adverse effect on the Company.
There can be no assurance that the Company will be able to maintain a sufficient
and adequate supply of products in its own inventory or that the Company will be
able to cause its distributors to maintain a sufficient and adequate supply of
products to avoid such a disruption.
 
INCREASED LEVERAGE
 
     As a result of the sale of the Notes, the Company's ratio of total debt to
total capitalization would have increased on a pro forma basis from
approximately .4% to approximately 57.0% at December 31, 1997. As a result of
this increased debt level, the Company's principal and interest obligations
increased substantially. The degree to which the Company has borrowed funds
pursuant to the Notes could limit the amount of additional financing the Company
may obtain, and/or may result in terms and conditions less favorable than it
currently has or would have for any additional financing. Increased borrowings
could make it more vulnerable to economic downturns and competitive pressures.
The Company's increased leverage could also materially and adversely affect its
liquidity, as a substantial portion of available cash from operations may have
to be applied to meet debt service requirements, and, in the event of a cash
shortfall, the Company could be forced to reduce other expenditures to be able
to meet such requirements.
 
                                        7
<PAGE>   11
 
DEPENDENCE ON THIRD-PARTY REIMBURSEMENT
 
     The Company's products are generally purchased by health care providers,
which then seek reimbursement from various public and private third-party
payors, such as Medicare, Medicaid and indemnity insurers, for health care
services provided to patients. Government and private third-party payors are
increasingly attempting to contain health care costs by limiting both the extent
of coverage and the reimbursement rate for new diagnostic and therapeutic
products and services. The Health Care Financing Administration of the United
States Department of Health and Human Services ("HCFA"), which administers
Medicare, and most private insurance companies do not provide reimbursement for
services that they determine to be experimental in nature or that are not
considered "reasonable and necessary" for diagnosis or treatment. Many private
insurers are influenced by HCFA actions in making their own coverage decisions
on new products or services. There can be no assurance that third-party
reimbursement for the services provided using the Company's products will
continue to be available to its customers or that any such reimbursement will be
adequate. Disapproval of, or limitations in, coverage by HCFA or other
third-party payors could materially and adversely affect market acceptance of
the Company's products which could, in turn, have a material adverse effect on
the Company's business, financial condition and results of operations.
 
NO ASSURANCE OF REGULATORY CLEARANCE; STRICT GOVERNMENTAL REGULATION
 
     The production and marketing of the Company's current products and the
products the Company intends to introduce in the future are subject to
regulations by numerous governmental authorities, including the Food and Drug
Administration ("FDA") and corresponding state and foreign agencies. In the
United States, the development, manufacture and promotion of medical devices are
regulated by the FDA under the Federal Food, Drug, and Cosmetic Act (the
"FFDCA"). Adverse FDA action could have a material adverse effect on the
Company.
 
     The Company's 3030 Stationary Pump and 6060 Ambulatory Pump, and the
related disposable tubing sets for use with these systems, have been cleared by
the FDA under a premarket notification procedure known as a "510(k) Submission,"
which generally takes less time to complete, and requires less information, than
the FDA's lengthy and expensive premarket approval ("PMA") process.
 
     The Company's Rocap division is currently registered with the FDA as a drug
manufacturer and repackager, and as a device manufacturer. Rocap intends to
develop new products and to make modifications to existing products. Such new or
modified products may require obtaining 510(k) clearance, new drug application
approval, or other FDA clearance. If it were determined that any such new or
modified products required prior FDA approval, the Company could be prohibited
from marketing such products until the necessary approvals were obtained as
would any other manufacturer. Such approvals could prove costly and time
consuming to obtain. In addition, there can be no assurance the Company will
obtain such clearances on a timely basis, if at all, for any new product and/or
modification to an existing product. If any such clearance is granted, there can
be no assurance that it will not contain significant limitations in the form of
warnings, precautions, or contraindications with respect to conditions of use.
 
     The Company believes that the original 510(k) clearance for the 6060
Ambulatory Pump permits the Company to market the MediVIEW software with the
6060 Ambulatory Pump in the United States without a new 510(k) Submission.
However, there can be no assurance that the FDA would agree with the Company's
determination. If in the future the FDA concludes that the MediVIEW software
system for use with the 6060 Ambulatory Pump required a new 510(k) Submission,
the FDA could prohibit the Company from marketing the MediVIEW software system
for this use until the Company filed a new 510(k) Submission and obtained
clearance from the FDA. If this occurs, the FDA could also take regulatory
action against the Company for its prior distribution of the MediVIEW software
system with the 6060 Ambulatory Pump.
 
     The Company has determined that the PumpMaster does not constitute a
medical device under the statutory definition and, therefore, did not file a
510(k) Submission with respect to this product. There can be no assurance that
the FDA will agree with the Company's determination in this regard. If the FDA
were to determine that the PumpMaster is a medical device that requires a 510(k)
Submission prior to its commercial
 
                                        8
<PAGE>   12
 
distribution, the FDA could suspend further commercial distribution of the
PumpMaster and take regulatory action against the Company for its prior
distribution of the product.
 
     The Company's new products and new applications for existing products may
require FDA clearance or approval prior to marketing. The FDA regulatory
requirements and review criteria for software-related medical devices could
adversely effect the Company's introduction of new software products, or devices
that incorporate software, in the future. The product clearance process for
future products can be lengthy, expensive and uncertain. There can be no
assurance that market clearances will be forthcoming in a timely manner, if at
all, or that the FDA will not require more extensive clinical evaluations, other
information or a PMA submission. Moreover, the clearances, if granted, could
limit the uses for which the product could be marketed. Failure to obtain, or
delays caused by, regulatory clearances or approvals could have a material
adverse affect on the Company's business, financial condition and results of
operations.
 
     In October, 1996, the Company learned of a defect in a software feature of
certain units of the 6060 Ambulatory Pump. The Company initiated a recall of
these units to correct the problem with an upgrade of the software. Pursuant to
FDA regulations, the Company notified the FDA of the recall and has updated the
FDA of the progress of the recall, which is now approximately 98% complete. The
FDA reported this recall in the January 15, 1997, issue of the FDA Enforcement
Report. In addition, in April, 1997, the FDA notified the Company of changes to
its classification of certain drugs and devices produced by the Company. In
June, 1997, the FDA responded to the Company's reply by noting that the Company
has addressed the regulatory issues raised in April. There can be no assurance
that the FDA will not take further action with respect to these matters.
 
     The Company is also subject to strict domestic and foreign regulation and
supervision regarding the development, manufacturing, marketing, labeling,
distribution, and promotion of its products. This includes periodic inspections
of the Company's manufacturing facility by the FDA to determine compliance with
GMP requirements, which are set forth in the FDA's Quality System ("QS")
regulations. There can be no assurance that the Company will be able to attain
or maintain compliance with GMP requirements.
 
     Failure to comply with the regulations outlined above may result in severe
governmental sanctions. Noncompliance with applicable requirements can result
in, among other things, rejection or withdrawal of premarket clearance or
approval for devices, recall or seizure of products, total or partial suspension
of production, fines, injunctions, and civil and criminal penalties. The FDA
also has the authority to request repair, replacement or refund of the cost of
any devices manufactured or sold by the Company. Any of these sanctions could
have a material adverse effect on the Company's business, financial condition or
results of operations.
 
PRODUCT LIABILITY EXPOSURE
 
     Manufacturers of medical devices face the possibility of substantial
liability for damages in the event that the use of their products is alleged to
have resulted in adverse effects to a patient. The Company maintains product
liability insurance with coverage limits of $12.0 million per occurrence with an
annual aggregate policy limit of $7.0 million. The Company's product liability
insurance provides coverage only for products currently manufactured and
distributed. There can be no assurance that liability claims will not exceed the
limits of such coverage or that such insurance will continue to be available on
commercially reasonable terms or at all. Furthermore, the Company does not
maintain insurance that would provide coverage for any costs or losses resulting
from any required recall of its products due to alleged defects, whether
instituted by the Company or a regulatory agency.
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
     During the year ended December 31, 1997, the Company derived approximately
3% of its revenues from international sales, resulting in exposure to certain
risks. Fluctuations in exchange rates of the U.S. dollar against foreign
currencies may reduce demand for, or the profitability of, the Company's
products sold overseas. In addition, the Company's international sales may be
affected by economic or political instability and domestic and foreign
governmental regulations, including export license requirements, trade
restrictions,
                                        9
<PAGE>   13
 
changes in tariffs, regulatory approval for marketing products or similar
factors. Finally, the laws of certain foreign countries may not protect the
Company's intellectual property rights to the same extent as do the laws of the
United States.
 
QUARTERLY FLUCTUATIONS
 
     The Company's quarterly revenues and operating results have varied
significantly in the past and may continue to do so in the future. In
particular, the Company's distributors and other customers may purchase several
months of inventory at one time which may cause fluctuations in quarterly
revenues. Future revenues and operating results may also fluctuate significantly
from quarter to quarter and will depend upon, among other factors: (i) demand
for the Company's products and new product introductions by the Company or its
competitors or transitions to new products, (ii) the timing of orders and
shipments, (iii) the mix of sales between products, (iv) competition, including
pricing pressures, (v) the timing of regulatory and third-party reimbursement
approvals, (vi) expansion of the Company's assembly capacity and the Company's
ability to assemble or manufacture its products efficiently, and (vii) the
timing of research and development expenditures. Accordingly, period-to-period
comparisons of the Company's revenues and operating results should not be relied
upon as an indication of future performance, and the results of any quarterly
period may not be indicative of results to be expected for a full year.
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's future performance depends in significant part upon the
continued service of its senior management and other key personnel. Because the
Company has a relatively small number of employees when compared to other
companies in the same industry, its dependence on maintaining its employees is
particularly significant. There can be no assurance that the Company's current
employees will continue to work for the Company. Loss of services of key
employees could have a material adverse effect on the Company's business,
results of operations and financial condition. The Company is also dependent on
its ability to attract and retain additional high quality personnel. The Company
may need to grant additional options to key employees and provide other forms of
incentive compensation to attract and retain key personnel.
 
INFLUENCE OF LIMITED NUMBER OF STOCKHOLDERS
 
     The directors and executive officers of the Company and certain existing
stockholders may be able to influence the Company's affairs and business,
including any determination with respect to a change in control of the Company,
future issuances of Common Stock or other securities by the Company, declaration
of dividends on the Company's Common Stock and the election of directors. Such
influence could have the effect of delaying, deferring or preventing a change in
control of the Company which could deprive the Company's stockholders of the
opportunity to sell their shares of Common Stock at prices higher than
prevailing market prices.
 
ABSENCE OF PUBLIC MARKET FOR NOTES
 
     There is no existing trading market for the Notes and there can be no
assurance as to the liquidity of any such market that may develop for the Notes,
the ability of the holders of Notes to sell such securities, the price at which
the holders of the Notes would be able to sell such securities or whether a
trading market, if it develops, will continue. The Notes have been designated
for trading on the PORTAL Market. The Notes sold pursuant to this Prospectus are
not expected to remain eligible for trading on the PORTAL Market. The Company
does not intend to apply for listing of the Notes on any securities exchange or
for inclusion of the Notes on any automated quotation system. If a liquid market
for the Notes fails to develop or be maintained, the trading price of the Notes
could be adversely affected. If a trading market were to develop, the Notes
could trade at prices higher or lower than their principal amount, depending
upon many factors, including prevailing interest rates, the price of the Common
Stock, the market for similar securities and the operating results of the
Company.
 
                                       10
<PAGE>   14
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
     The securities markets have, from time to time, experienced extreme price
and volume fluctuations which often have been unrelated to the operating
performance of particular companies. The market prices of the common stock of
many publicly-held medical device companies have been in the past, and are
expected to be, volatile. Announcements of technological or medical innovations
or new commercial products by the Company or its competitors, developments or
disputes concerning patents or proprietary rights, changes in regulatory or
medical reimbursement policies, and economic and other external factors, as well
as period-to-period fluctuations in the financial results of the Company, may
have a significant impact on the market price and marketability of the Common
Stock.
 
ANTI-TAKEOVER CONSIDERATIONS
 
     Certain provisions of the Company's Certificate of Incorporation and Bylaws
and the Delaware General Corporation Law may have the effect of making it more
difficult for a third party to acquire, or of discouraging a third party from
attempting to acquire, control of the Company. Such provisions could limit the
price that certain investors might be willing to pay in the future for shares of
the Company's Common Stock. Pursuant to the Company's Certificate of
Incorporation, the Board of Directors is authorized to fix the rights,
preferences, privileges and restrictions, including voting rights, of unissued
shares of the Company's preferred stock and to issue such stock without any
further vote or action by the Company's stockholders. The rights of the holders
of Common Stock will be subject to and may be adversely affected by the rights
of the holders of any preferred stock that may be created and issued in the
future. In addition, stockholders do not have the right to cumulative voting for
the election of directors. The Company's Bylaws include a number of provisions
which may have the effect of discouraging persons from pursuing non-negotiated
takeover attempts. Specifically, the Company's Bylaws provide for a staggered
board whereby only one-third of the total number of directors are replaced or
re-elected each year. The Bylaws also require the affirmative vote of two-thirds
of the Company's issued and outstanding capital stock to remove a director.
 
     In certain circumstances involving a Change In Control, each holder may
require the Company to repurchase all or a portion of such holder's Notes. The
repurchase obligation could have the effect of making it more difficult for a
third party to acquire, or of discouraging a third party from attempting to
acquire, control of the Company.
 
     The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203"), which restricts certain transactions and business
combinations between a corporation and an "Interested Stockholder" owning 15% or
more of the corporation's outstanding voting stock for a period of three years
from the date the stockholder becomes an Interested Stockholder. Subject to
certain exceptions, unless the transaction is approved in a prescribed manner,
Section 203 prohibits significant business transactions such as a merger with,
disposition of assets to or receipt of disproportionate financial benefits by
the Interested Stockholder, or any other transactions that would increase the
Interested Stockholder's proportionate ownership of any class or series of the
corporation's stock.
 
LIMITATION ON REPURCHASE OF NOTES
 
     In certain circumstances involving a Change of Control (as such term is
defined below), each holder may require the Company to repurchase all or a
portion of such holder's Notes. In such event, there can be no assurance that
the Company would have sufficient financial resources or would be able to
arrange financing to pay the repurchase price. The Company's ability to
repurchase the Notes in such event may be limited by law, the Indenture and the
terms of other agreements relating to borrowings that constitute Indebtedness,
as such Indebtedness or agreements may be entered into, replaced, supplemented
or amended at any time or from time to time. The Company may not have the
financial ability to repurchase the Notes in the event payment of Indebtedness
is accelerated. See "Description of Notes -- Repurchase at the Option of
Holders."

SUBORDINATION
 
     The Notes are unsecured obligations of the Company and rank pari passu with
all existing and future unsecured Indebtedness and other liabilities of the
Company but are effectively subordinated to all existing and future secured
obligations of the Company and to all existing and future Indebtedness and other
liabilities of any Subsidiaries of the Company. At March 31, 1998, the aggregate
amount of outstanding secured obligations of the Company and outstanding
Indebtedness and other liabilities of Subsidiaries of the Company to which the
Notes are effectively subordinated was zero. The Indenture does not limit the
amount of additional Indebtedness which the Company can create, incur, assume or
guaranty. Because the Notes are unsecured, in the event of insolvency,
bankruptcy, liquidation, reorganization or winding up of the business of the
Company or upon default in payment with respect to any secured Indebtedness or
an event of default with respect to such Indebtedness resulting in the
acceleration thereof, the assets of the Company will be available to pay the
amounts due on the Notes only after all secured Indebtedness has been paid in
full.
 
ORIGINAL ISSUE DISCOUNT: POSSIBLE UNFAVORABLE TAX CONSEQUENCES FOR HOLDERS OF
NOTES
 
     The Company currently expects that the Notes will not be sold by the
Selling Security Holders with original issue discount ("OID"). Potential
purchasers should be aware, however, that if the Notes are sold by the Selling
Security Holders pursuant to this offer at a substantial discount from the
stated principal amount at maturity, OID (that is, the difference between the
stated redemption price at maturity and the price of the Notes) will be
includible as interest income periodically in a United States Holders' gross
income in advance of receipt of the cash payments to which the income is
attributable. See "Certain United States Federal Income Tax Considerations."
Similar rules may apply under state and other tax laws.
 
     The Company is required to furnish certain information to the Internal
Revenue Service, and will furnish annually to record holders of Notes,
information with respect to interest and OID, if any, accruing during the
calendar year. No assurance can be given that the Internal Revenue Service will
not challenge the accuracy of the reported information. Subsequent holders who
purchase Notes for an amount other than the adjusted issue price and/or on a
date other than the last day of an accrual period will be required to determine
for themselves the amount of OID, if any, they are required to include in gross
income for United States federal income tax purposes.

                                USE OF PROCEEDS
 
     All proceeds from any sales of the Notes or the Shares by the Selling
Security Holders will inure to the benefit of the Selling Security Holders. The
Company will receive none of the proceeds from the sale of the Notes or the
Shares offered hereby.
 
                       RATIO OF EARNINGS TO FIXED CHARGES
 
     The following table sets forth the Company's consolidated ratio of earnings
to fixed charges for the periods shown.

     For the purposes of calculating ratio of earnings to fixed charges, (i)
earnings consist of consolidated income (loss) before income taxes, plus fixed
charges, and (ii) fixed charges consist of interest expense incurred and the
portion of rental expense under operating lease deemed by the Company to be
representative of the interest factor.
 
     Earnings were inadequate to cover fixed charges for the years ended
December 31, 1993, 1994, 1995 and 1996 by $2,821,000, $3,555,000, $6,036,000 and

                            SELLING SECURITY HOLDERS
 
     The Notes were originally issued by the Company in a private placement and
were resold by the Initial Purchaser thereof to qualified institutional buyers
(within the meaning of Rule 144A under the Securities Act) or other
institutional accredited investors (as defined in Rule 501(a)(1), (2), (3) or
(7) under the Securities Act) in transactions exempt from registration under the
Securities Act, and in sales outside the United States to persons other than
U.S. persons in reliance upon Regulation S under the Securities Act. The
Securities that may be offered pursuant to this Prospectus will be offered by
the Selling Security Holders. The following table sets forth certain information
as of June 1, 1998, concerning the principal amount of Notes beneficially owned
by each Selling Security Holder and the number of Shares that may be offered
from time to time pursuant to this Prospectus.
 
     From time to time, Salomon Smith Barney or its affiliates have provided,
and may continue to provide, investment banking services to the Company, for
which they received or will receive customary fees. None of the other Selling
Security Holder has had any position, office or other material relationship with
the Company or its affiliates within the past three years.

(1) Assume conversion of the full amount of the Notes held by such holder or the
    initial conversion price of $40.46 per share; such conversion price is
    subject to adjustment as described under "Description of the Notes --
    Conversion." Accordingly, the number of shares of Common Stock issuable upon
    conversion of the Notes may increase or decrease from time to time. Under
    the terms of the Indenture, fractional shares will not be issued upon
    conversion of the Notes; cash will be paid in lieu of fractional shares, if
    any.
 
(2) None of the Selling Security Holders will own more than 1% of the total
    outstanding shares of Common Stock after completion of the offering. The
    percentage was computed in accordance with Rule 13(d)-3(i) promulgated under
    the Exchange Act based upon 10,578,524 shares of Common Stock outstanding as
    of June 1, 1998.
 
     The preceding table has been prepared based upon the information furnished
to the Company by the Selling Security Holders. The names of such Selling
Security Holders were provided to the Company by LaSalle National Bank, as
trustee (the "Trustee") under the Indenture, and by The Depository Trust Company
("DTC").
 
     The Selling Security Holders identified above may have sold, transferred or
otherwise disposed of, in transactions exempt from the registration requirements
of the Securities Act, all or a portion of their Notes since the date on which
the information in the preceding table is presented. Information concerning the
Selling Security Holders may change from time to time and any such changed
information will be set forth in supplements to this Prospectus if and when
necessary. Because the Selling Security Holders may offer all or only a portion
of the Notes or the Shares that they hold pursuant to the offering contemplated
by this Prospectus, no definitive determination can be made as to the amount of
the Notes or the Shares that will be held by the Selling Security Holders upon
the termination of the offering. The information provided above regarding
holdings of Notes and Shares following the offering contemplated by this
Prospectus assume that all of the Notes and Shares covered hereby are sold. See
"Plan of Distribution."
 
                              PLAN OF DISTRIBUTION
 
     Pursuant to a Registration Agreement dated as of April 14, 1998 (the
"Registration Agreement"), between the Company and Salomon Smith Barney (the
"Initial Purchaser"), the Company filed the Registration Statement, of which
this Prospectus forms a part, filed with the Commission covering the resale of
the Securities. The Company has agreed to use all reasonable efforts to keep the
Registration Statement
 
                                       15
<PAGE>   19
 
effective until April 14, 2000 (or such earlier date when the holders of the
Shares are able to sell all such Shares immediately without restriction pursuant
to Rule 144(k) under the Securities Act or any successor rule thereto or
otherwise). The Company will be permitted to suspend the use of this Prospectus
in connection with sales of Shares by holders during certain periods of time
under certain circumstances relating to pending corporate developments and
public filings with the SEC and similar events. The specific provisions relating
to the registration rights described above are contained in the Registration
Agreement, and the foregoing summary is qualified in its entirety by reference
to the provisions of such agreement.
 
     Sales of the Securities may be effected by or for the account of the
Selling Security Holders from time to time in transactions (which may include
block transactions in the case of the Shares) on any exchange or market on which
such securities are listed or quoted, as applicable, in negotiated transactions,
through a combination of such methods of sale, or otherwise, at fixed prices
that may be changed, at market prices prevailing at the time of sale, at prices
related to prevailing market prices, or at negotiated prices. The Selling
Security Holders may effect such transactions by selling the Notes or Shares
directly to purchasers, through broker-dealers acting as agents for the Selling
Security Holders, or to broker-dealers who may purchase Notes or Shares as
principals and thereafter sell the Notes or Shares from time to time in
transactions (which may include block transactions in the case of the Shares) on
any exchange or market on which such securities are listed or quoted, as
applicable, in negotiated transactions, through a combination of such methods of
sale, or otherwise. In effecting sales, broker-dealers engaged by Selling
Security Holders may arrange for other broker-dealers to participate. Such
broker-dealers, if any, may receive compensation in the form of discounts,
concessions or commissions from the Selling Security Holders and/or the
purchasers of the Notes or Shares from whom such broker-dealers may act as
agents or to whom they may sell as principals, or both (which compensation as to
a particular broker-dealer might be in excess of customary commissions).
 
     The Selling Security Holders and any broker-dealers, agents or underwriters
that participate with the Selling Security Holders in the distribution of the
Notes or Shares may be deemed to be "underwriters" within the meaning of the
Securities Act. Any commissions paid or any discounts or concessions allowed to
any such persons, and any profits received on the resale of the Notes or Shares
offered hereby and purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act.
 
     At the time a particular offering of the Notes or the Shares is made and to
the extent required, the aggregate principal amount of Notes and number of
Shares being offered, the name or names of the Selling Security Holders, and the
terms of the offering, including the name or names of any underwriters, broker-
dealers or agents, any discounts, concessions or commissions and other terms
constituting compensation from the Selling Security Holders, and any discounts,
concessions or commissions allowed or reallowed or paid to broker-dealers, will
be set forth in an accompanying Prospectus Supplement.
 
     Pursuant to the Registration Agreement, the Company has agreed to pay all
expenses incident to the offer and sale of the Securities offered by the Selling
Security Holders hereby, except that the Selling Security Holders will pay all
underwriting discounts and selling commissions, if any. The Company has agreed
to indemnify the Selling Security Holders against certain liabilities, including
liabilities under the Securities Act, and to contribute to payments the Selling
Security Holders may be required to make in respect thereof. Each Selling
Security Holder severally agrees to indemnify and hold harmless (i) the Company,
(ii) each of its directors, (iii) each of its officers who signed the
Registration Statement and (iv) each person who controls the Company within the
meaning of either the Securities Act or the Exchange Act to the same extent as
the foregoing indemnity from the Company to each such Selling Security Holder,
but only with reference to written information relating to such Selling Security
Holder furnished to the Company by or on behalf of such Selling Security Holder.
 
     To comply with the securities laws of certain jurisdictions, if applicable,

                              DESCRIPTION OF NOTES
 
GENERAL
 
     The Notes were issued pursuant to an Indenture dated as of April 14, 1998
(the "Indenture"), between the Company and LaSalle National Bank, as trustee
(the "Trustee"). A copy of the Indenture and the Registration Agreement is
available from the Trustee or the Company upon request by a registered holder of
Notes. The following summary of certain provisions of the Indenture and the
Registration Agreement does not purport to be complete and is qualified in its
entirety by reference to the Indenture and the Registration Agreement, including
the definitions in the Indenture of certain terms used in the following summary.
The definitions of certain terms used in the following summary are set forth
below under "-- Certain Definitions."
 
     The Notes are unsecured obligations of the Company and rank pari passu with
all existing and future unsecured Indebtedness and other liabilities of the
Company but are subordinated to all existing and future secured obligations of
the Company and to all existing and future Indebtedness and other liabilities of
any subsidiaries of the Company. At March 31, 1998, the aggregate amount of
outstanding secured obligations of the Company and outstanding Indebtedness and
other liabilities of Subsidiaries of the Company to which the Notes are
effectively subordinated was zero. The Indenture does not restrict the
incurrence of any other Indebtedness or liabilities by the Company or its
Subsidiaries.
 
     The Notes have been designated for trading on the PORTAL Market.
 
PRINCIPAL, MATURITY AND INTEREST
 
     The Notes bear interest from April 14, 1998, at the rate of 6% per annum,
and will mature on April 15, 2005.
 
     Interest on the Notes are payable semiannually on April 15 and October 15
of each year (each an "Interest Payment Date"), commencing on October 15, 1998,
to holders of record at the close of business on the April 1 or October 1 (each
a "Regular Record Date") immediately preceding such Interest Payment Date.
Interest will be computed on the basis of a 360-day year comprised of twelve
30-day months.
 
     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 April 14, 1998.
 
     The Notes are payable both as to principal and interest at the office or
agency of the Company maintained for such purpose within Chicago, Illinois or,
subject to applicable laws and regulations, at the office of any Paying Agent,
or, at the option of the Company, payment of interest may be made by check
mailed to the holders of the Notes at their respective addresses set forth in
the register of holders of Notes. Until otherwise designated by the Company, the
Company's office or agency in Chicago, Illinois, will be the office of the
Trustee maintained for such purpose. The Notes were issued in registered form,
without coupons, and in denominations of $1,000 and integral multiples thereof.
 
     If a payment date is not a Business Day at a place of payment, payment may
be made at that place on the next succeeding Business Day, and no interest shall
accrue for the intervening period.
 
     The Company has initially appointed the Trustee at its corporate trust
office in the City of Chicago as the Paying Agent and Conversion Agent. The
Company may at any time terminate the appointment of the Paying Agent or
Conversion Agent and appoint additional or other Paying Agents and Conversion
Agents, provided that until the Notes have been delivered to the Trustee for
cancellation, or moneys sufficient to pay the principal of, premium, if any, and
interest on the Notes have been made available for payment and either paid or
returned to the Company as provided in the Indenture, it will maintain an office
or agency in Chicago,
 
                                       17
<PAGE>   21
 
Illinois for payments with respect to the Notes and for the surrender of Notes
for conversion. Notice of any such termination or appointment and of any change
in the office through which the Paying Agent or Conversion Agent will act will
be given in accordance with "-- Selection and Notices" below.
 
OPTIONAL REDEMPTION
 
     The Notes will not be subject to redemption prior to April 19, 2001 and
will be redeemable on such date and thereafter at the option of the Company, in
whole or in part (in any integral multiple of $1,000), upon not less than 30 nor
more than 60 days' prior notice by mail at the following redemption prices
(expressed as percentages of the principal amount), in each case, together with
accrued interest to the redemption date (subject to the right of holders of
record on the relevant record date to receive interest due on an Interest
Payment Date). If redeemed during the 12-month period beginning April 15 of the
years indicated (April 19 in the case of the year 2001), such redemption price
shall be as indicated:

     On or after the redemption date, interest will cease to accrue on the
Notes, or portion thereof, called for redemption.
 
MANDATORY REDEMPTION
 
     The Company is not required to make mandatory redemption or sinking fund
payments with respect to the Notes.
 
REPURCHASE AT THE OPTION OF HOLDERS
 
     Upon the occurrence of a Designated Event (as such term is defined below),
each holder of Notes shall have the right to require the Company 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 "Designated Event
Offer") at a purchase price equal to 100% of the principal amount thereof,
together with accrued and unpaid interest thereon to the Designated Event
Payment Date (the "Designated Event Payment"). Within 30 days following any
Designated Event, the Company shall mail a notice to each holder stating: (1)
that the Designated Event Offer is being made pursuant to the covenant described
in this paragraph and that all Notes tendered will be accepted for payment; (2)
the purchase price and the purchase date, which shall be no earlier than 30 days
nor later than 60 days from the date such notice is mailed (the "Designated
Event Payment Date"); (3) that any Notes not tendered will continue to accrue
interest; (4) that, unless the Company defaults in the payment of the Designated
Event Payment, all Notes accepted for payment pursuant to the Designated Event
Offer shall cease to accrue interest after the Designated Event Payment Date;
(5) that holders electing to have any Notes purchased pursuant to a Designated
Event Offer will be required to surrender the Notes, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Notes completed, to a
Paying Agent at the address specified in the notice prior to the close of
business on the third Business Day preceding the Designated Event Payment Date;
(6) that holders will be entitled to withdraw their election if a Paying Agent
receives, not later than the close of business on the second Business Day
preceding the Designated Event Payment Date, a telegram, telex, facsimile
transmission or letter setting forth the name of the holder, the principal
amount of Notes delivered for purchase, and a statement that such holder is
withdrawing his election to have all or a portion of such Notes purchased and
specifying the amount of such Notes (which must be equal to $1,000 in principal
amount or an integral multiple thereof) with respect to which such withdrawal is
effective; and (7) that holders whose Notes are being purchased only in part
will be issued new Notes equal in principal amount to the unpurchased portion of
the Notes surrendered, which unpurchased portion must be equal to $1,000 in
principal amount or an integral multiple thereof.
 
                                       18
<PAGE>   22
 
     The Company will comply with the requirements of Rules 13e-4 and 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 in connection with a Designated Event.
 
     On the Designated Event Payment Date, the Company will, to the extent
lawful, (1) accept for payment Notes or portions thereof duly tendered pursuant
to the Designated Event Offer, (2) deposit with the Trustee or a Paying Agent an
amount equal to the Designated Event Payment in respect of all Notes or portions
thereof so tendered and (3) deliver or cause to be delivered to the Trustee the
Notes so tendered together with an Officers' Certificate identifying the Notes
or portions thereof tendered to the Company. The Trustee or a Paying Agent shall
promptly mail to each holder of Notes so tendered payment in an amount equal to
the purchase price for such Notes, and the Trustee shall promptly authenticate
and mail to each holder a new certificate representing a Note equal in principal
amount to any unpurchased portion of the Notes surrendered, if any; provided
that each such new certificate representing a Note shall be in a principal
amount of $1,000 or an integral multiple thereof. The Company will publicly
announce the results of the Designated Event Offer on or as soon as practicable
after the Designated Event Payment Date.
 
     Except as described above with respect to a Designated Event, the Indenture
does not contain any other provisions that permit the holders of the Notes to
require that the Company repurchase or redeem the Notes in the event of a
takeover, recapitalization or similar restructuring.
 
     The Designated Event purchase feature of the Notes may in certain
circumstances make more difficult or discourage a takeover of the Company, and,
thus, the removal of incumbent management. The Designated Event purchase
feature, however, is not the result of management's knowledge of any specific
effort to accumulate the Company's stock or to obtain control of the Company by
means of a merger, tender offer, solicitation or otherwise, or part of a plan by
management to adopt a series of anti-takeover provisions. Instead, the
Designated Event purchase feature is a result of negotiations between the
Company and the Initial Purchaser. Management has no current intention to engage
in a transaction involving a Designated Event, although it is possible that the
Company could decide to do so in the future. Subject to the limitations on
mergers, consolidations and sales of assets described herein, the Company could,
in the future, enter into certain transactions, including acquisitions,
refinancings or other recapitalizations, that would not constitute a Designated
Event under the Indenture.
 
     The Company's ability to repurchase Notes upon the occurrence of a
Designated Event is subject to limitations. If a Designated Event were to occur,
there can be no assurance that the Company would have sufficient financial
resources, or would be able to arrange financing, to pay the repurchase price
for all Notes tendered by holders thereof. In addition, the terms of certain of
the Company's existing or future debt agreements and lease facilities may
prohibit the Company from purchasing any Notes under certain circumstances and
may also identify certain events that would constitute a Change in Control, as
well as certain other events with respect to the Company or certain of its
subsidiaries, which would constitute an event of default under such debt
agreements and lease facilities. In the event a Designated Event occurs at a
time when such prohibitions or restrictions are in effect, the Company could
seek the consent of its lenders or lessors to the purchase of Notes or could
attempt to refinance the borrowings that contain such prohibition. If the
Company does not obtain such a consent or repay such borrowings or leases, the
Company will be effectively prohibited from purchasing Notes. In such case, the
Company's failure to purchase tendered Notes would constitute an Event of
Default under the Indenture. Any such default may, in turn, cause a default
under other debt agreements or lease facilities of the Company.
 
     A "Designated Event" will be deemed to have occurred upon a Change of
Control or a Termination of Trading.
 
     A "Change of Control" will be deemed to have occurred when: (i) any
"person" or "group" (as such terms are used in Section 13(d) and 14(d) of the
Exchange Act) is or becomes the "beneficial owner" (as defined in Rules 13d-3
and 13d-5 under the Exchange Act) of shares representing more than 50% of the
combined voting power of the then outstanding securities entitled to vote
generally in elections of directors of the Company ("Voting Stock"), (ii) the
Company consolidates with or merges into any other corporation, or any other
corporation merges into the Company, and, in the case of any such transaction,
the outstanding
                                       19
<PAGE>   23
 
Common Stock of the Company is reclassified into or exchanged for any other
property or security, unless the stockholders of the Company immediately before
such transaction own, directly or indirectly immediately following such
transaction, at least a majority of the combined voting power of the outstanding
voting securities of the corporation resulting from such transaction in
substantially the same proportion as their ownership of the Voting Stock
immediately before such transaction, (iii) the Company conveys, transfers or
leases all or substantially all of its assets (other than to one or more
wholly-owned subsidiaries of the Company) or (iv) any time the Continuing
Directors do not constitute a majority of the Board of Directors of the Company
(or if applicable, a successor corporation to the Company).
 
     The definition of Change of Control includes a phrase relating to the
lease, transfer or conveyance of "all or substantially all" of the assets of the
Company. 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 Notes to require
the Company to repurchase such Notes as a result of a lease, transfer or
conveyance of less than all of the assets of the Company 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 Company who (i) was a member of such Board of
Directors on the date of the Indenture or (ii) was nominated for election or
elected to such Board of Directors with the approval of a majority of the
Continuing Directors who were members of such Board at the time of such
nomination or election.
 
     A "Termination of Trading" will be deemed to have occurred if the Common
Stock (or other common stock into which the Notes are then convertible) is
neither listed for trading on a United States national securities exchange nor
approved for trading on an established automated over-the-counter trading market
in the United States.
 
SELECTION AND NOTICE
 
     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. Notice 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. On and after the redemption date, interest
ceases to accrue on Notes or portions thereof called for redemption.
 
REGISTRATION RIGHTS
 
     The Company entered into a registration agreement with the Initial
Purchaser (the "Registration Agreement"), pursuant to which the Company is
required to use reasonable efforts to cause the Registration Statement of which
this Prospectus is a part to remain effective under the Securities Act until the
earlier of (a) April 14, 2000, (b) the date on which the Notes or the Shares may
be sold by non-affiliates of the Company pursuant to paragraph (k) of Rule 144
(or any successor provision) promulgated by the Commission under the Securities
Act and (c) the date as of which all the Notes or the Shares have been sold
pursuant to the Registration Statement. If the Company fails to keep the
Registration Statement continuously effective for the period specified above
(other than as a result solely of actions of any holders of securities covered
by the Registration Statement), then at such time as the Registration Statement
is no longer effective and on each date thereafter that is the successive 30th
day subsequent to such time and until the earliest of (i) the date that the
Registration Statement is again deemed effective, (ii) the date on which the
Notes or the Shares may be sold by non-affiliates of the Company pursuant to
paragraph (k) of Rule 144 (or any successor provision) promulgated by the
Commission under the Securities Act, (iii) April 14, 2000 and (iv) the date as
of which the Notes and/or the Shares are sold pursuant to the Registration
Statement, the per annum interest
 
                                       20
<PAGE>   24
 
rate on the Notes will increase by an additional 25 basis points; provided,
however, that the interest rate will not increase by more than 50 basis points
pursuant to this sentence. The Company shall have the right, however, to suspend
the use of this Prospectus, as more fully described below. For any period during
which the per annum interest rate on the Notes is increased pursuant to this
paragraph, each holder of restricted Common Stock issued upon conversion of the
Notes shall be entitled to receive liquidated damages from the Company as
follows: (i) for every 25 basis points by which the interest rate is increased
pursuant to this paragraph, such liquidated damages shall accrue at a rate equal
to $2.50 per annum per 24.7158 shares of Common Stock (subject to adjustment in
the event of a stock split, stock recombination, stock dividend and the like);
and (ii) any liquidated damages which have accrued pursuant to this paragraph
prior to the record date relating to any interest payment date shall be payable
on such interest payment date to the holders of record on such record date.
 
     The Company will provide or cause to be provided to each holder of the
Notes, or the Shares, copies of this Prospectus, notify or cause to be notified
each such holder when the Registration Statement for the Notes or the Shares has
become effective and take certain other actions as are required to permit
unrestricted resales of the Notes or the Shares. A holder of the Notes or the
Shares that sells such securities pursuant to this Prospectus will be required
to deliver a Prospectus to purchasers, will be subject to certain of the civil
liability provisions under the Securities Act in connection with such sales and
will be bound by the provisions of the Registration Agreement that are
applicable to such holder (including certain indemnification and contribution
rights or obligations).
 
     The Company will be permitted to suspend the use of the Prospectus for a
period not to exceed 30 days in any thee-month period or for three periods not
to exceed an aggregate of 90 days in any twelve-month period under certain
circumstances relating to pending corporate developments, public filings with
the Commission and similar events.
 
CONVERSION
 
     The holder of any Note have the right, exercisable at any time after 90
days following the date of original issuance thereof and prior to the close of
business on the Business Day immediately preceding the maturity date of the
Notes, to convert the principal amount thereof (or any portion thereof that is
an integral multiple of $1,000) into shares of Common Stock at a conversion
price of $40.46 per share, subject to adjustment as described below (the
"Conversion Price"), except that if a Note is called for redemption, the
conversion right will terminate at the close of business on the Business Day
immediately preceding the date fixed for redemption. Except as described below,
no adjustment will be made on conversion of any Notes for interest accrued
thereon or for dividends on any Common Stock issued. If Notes not called for
redemption are converted after a record date for the payment of interest and
prior to the next succeeding Interest Payment Date, such Notes must be
accompanied by funds equal to the interest payable on such succeeding Interest
Payment Date on the principal amount so converted. No fractional shares will be
issued upon conversion but a cash adjustment will be made for any fractional
shares.
 
     Beneficial owners of interests in a Note may exercise their right of
conversion by delivering to DTC the appropriate instruction form for conversion
pursuant to DTC's conversion program and, in the case of conversions through
Euroclear or Cede Bank, in accordance with Euroclear's or Cede Bank's normal
operating procedures when application has been made to make the underlying
Common Stock eligible for trading on Cede Bank or Euroclear. To convert a Note
held in certificated form into shares of Common Stock, a holder must (i)
complete and manually sign the conversion notice on the back of the Note (or
complete and manually sign a facsimile thereof) and deliver such notice to the
Trustee in Chicago, Illinois, (ii) surrender the Note to the Trustee in Chicago,
Illinois, (iii) if required, furnish appropriate endorsements and transfer
documents, (iv) if required, pay all transfer or similar taxes, and (v) if
required, pay funds equal to interest payable on the next interest payment date.
Pursuant to the Indenture, the date on which all of the foregoing requirements
have been satisfied is the date of surrender for conversion. Such notice of
conversion can be obtained from the Trustee at its corporate trust office or the
of lice of the Conversion Agent. As promptly as practicable on or after the
conversion date, the Company will issue and deliver to the Trustee a certificate
or certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment
                                       21
<PAGE>   25
 
in lieu of any fraction of a share in an amount determined as set forth below.
Such certificate will be sent by the Trustee to the Conversion Agent for
delivery to the holder. Such Common Stock issuable upon conversion of the Notes
will be fully paid and nonassessable. Any Note surrendered for conversion during
the period from the close of business on any Regular Record Date to the opening
of business on the next succeeding Interest Payment Date (except Notes called
for redemption on a redemption date or to be repurchased on a Designated Event
Payment Date during such period) must be accompanied by payment of an amount
equal to the interest payable on such Interest Payment Date on the principal
amount of Notes being surrendered for conversion. In the case of any Note which
has been converted after any Regular Record Date, but on or before the next
Interest Payment Date, interest on such Note shall be payable on such Interest
Payment Date notwithstanding such conversion. Such interest shall be paid to the
holder of such Note on such Regular Record Date. No other payment or adjustment
for interest, or for any dividends in respect of Common Stock, will be made upon
conversion. Holders of Common Stock issued upon conversion will not be entitled
to receive any dividends payable to holders of Common Stock as of any record
time before the close of business on the conversion date.
 
     The Conversion Price is subject to adjustment upon the occurrence of
certain events, including: (i) the issuance of shares of Common Stock as a
dividend or distribution on the Common Stock; (ii) the subdivision or
combination of the outstanding Common Stock, (iii) the issuance to substantially
all holders of Common Stock of rights or warrants to subscribe for or purchase
Common Stock (or securities convertible into Common Stock) at a price per share
less than the then Current Market Price per share, as defined; (iv) the
distribution of shares of capital stock of the Company (other than Common
Stock), evidences of Indebtedness or other assets (excluding dividends in cash,
except as described in clause (v) below) to all holders of Common Stock; (v) the
distribution, by dividend or otherwise, of cash to all holders of Common Stock
in an aggregate amount that, together with the aggregate of any other
distributions of cash that did not trigger a Conversion Price adjustment to all
holders of its Common Stock within the 12 months preceding the date fixed for
determining the stockholders entitled to such distribution and all Excess
Payments in respect of each tender offer or other negotiated transaction by the
Company or any of its Subsidiaries for Common Stock concluded within the
preceding 12 months not triggering a Conversion Price adjustment, exceeds 15% of
the product of the Current Market Price per share (determined as set forth
below) on the date fixed for the determination of stockholders entitled to
receive such distribution times the number of shares of Common Stock outstanding
on such date; (vi) payment of an Excess Payment in respect of a tender offer or
other negotiated transaction by the Company or any of its Subsidiaries for
Common Stock, if the aggregate amount of such Excess Payment, together with the
aggregate amount of cash distributions made within the preceding 12 months not
triggering a Conversion Price adjustment and all Excess Payments in respect of
each tender offer or other negotiated transaction by the Company or any of its
Subsidiaries for Common Stock concluded within the preceding 12 months not
triggering a Conversion Price adjustment, exceeds 15% of the product of the
Current Market Price per share (determined as set forth below) on the expiration
of such tender offer or the date of payment of such negotiated transaction
consideration times the number of shares of Common Stock outstanding on such
date; and (vii) the distribution to substantially all holders of Common Stock of
rights or warrants to subscribe for securities (other than those securities
referred to in clause (iii) above). In the event of a distribution to
substantially all holders of Common Stock of rights to subscribe for additional
shares of the Company's capital stock (other than those securities referred to
in clause (iii) above), the Company may, instead of making any adjustment in the
Conversion Price, make proper provision so that each holder of a Note who
converts such Note after the record date for such distribution and prior to the
expiration or redemption of such rights shall be entitled to receive upon such
conversion, in addition to shares of Common Stock, an appropriate number of such
rights. No adjustment of the Conversion Price will be made until cumulative
adjustments amount to one percent or more of the Conversion Price as last
adjusted.
 
     If the Company reclassifies or changes its outstanding Common Stock, or
consolidates with or merges into any person or transfers or leases all or
substantially all its assets, or is a party to a merger that reclassifies or
changes its outstanding Common Stock, the Notes will become convertible into the
kind and amount of securities, cash or other assets which the holders of the
Notes would have owned immediately after the transaction if the holders had
converted the Notes immediately before the effective date of the transaction.
 
                                       22
<PAGE>   26
 
     The Indenture also provides that if rights, warrants or options expire
unexercised the Conversion Price shall be readjusted to take into account the
actual number of such warrants, rights or options which were exercised.
 
     In the Indenture, the "Current Market Price" per share of Common Stock on
any date shall be deemed to be the average of the Daily Market Prices for the
shorter of (i) 30 consecutive Business Days ending on the last full trading day
on the exchange or market referred to in determining such Daily Market Prices
prior to the time of determination (as defined in the Indenture) or (ii) the
period commencing on the date next succeeding the first public announcement of
the issuance of such rights or warrants or such distribution through such last
full trading day prior to the time of determination.
 
     "Excess Payment" means the excess of (A) the aggregate of the cash and fair
market value of other consideration paid by the Company or any of its
Subsidiaries with respect to the shares acquired in the tender offer or other
negotiated transaction over (B) the Daily Market Price on the Trading Day
immediately following the completion of the tender offer or other negotiated
transaction multiplied by the number of acquired shares.
 
     The Company from time to time may to the extent permitted by law reduce the
Conversion Price by any amount for any period of at least 20 days (each such
reduction, an "Induced Conversion Adjustment"), in which case the Company shall
give at least 15 days' notice of such reduction, if the Board of Directors has
made a determination that such reduction would be in the best interests of the
Company, which determination shall be conclusive. The Company may, at its
option, make such reductions in the Conversion Price, in addition to those set
forth above, as the Board of Directors deems advisable to avoid or diminish any
income tax to holders of Common Stock resulting from any dividend or
distribution of stock (or rights to acquire stock) or from any event treated as
such for income tax purposes.
 
MERGER, CONSOLIDATION OR SALE OF ASSETS
 
     The Indenture provides that the Company may not consolidate or merge with
or into any Person (whether or not the Company is the surviving corporation), or
sell, assign, transfer, lease, convey or otherwise dispose of all or
substantially all of its properties or assets unless (i) (a) the Company is the
surviving or continuing corporation or (b) the Person formed by or surviving any
such consolidation or merger (if other than the Company) or the Person which
acquires by sale, assignment, transfer, lease, conveyance or other disposition
the properties and assets of the Company is a corporation organized or existing
under the laws of the United States, any state thereof or the District of
Columbia; (ii) the entity or Person formed by or surviving any such
consolidation or merger (if other than the Company) or the Person to which such
sale, assignment, transfer, lease, conveyance or other disposition will have
been made assumes all the Obligations of the Company, pursuant to a supplemental
indenture in a form reasonably satisfactory to the Trustee, under the Notes and
the Indenture; (iii) such sale, assignment, transfer, lease, conveyance or other
disposition of all or substantially all of the Company's properties or assets
shall be as an entirety or virtually as an entirety to one Person and such
Person shall have assumed all the obligations of the Company, pursuant to a
supplemental indenture in a form reasonably satisfactory to the Trustee, under
the Notes and the Indenture; (iv) immediately after such transaction no Default
or Event of Default exists; and (v) the Company or such Person shall have
delivered to the Trustee an Officers' Certificate and an Opinion of Counsel,
each stating that such transaction and the supplemental indenture comply with
the Indenture and that all conditions precedent in the Indenture relating to
such transaction have been satisfied.
 
REPORTS
 
     Whether or not required by the rules and regulations of the Commission, so
long as any Notes are outstanding, the Company will file with the Commission and
furnish to the holders of Notes all quarterly and annual financial information
required to be contained in a filing with the Commission on Forms 10-Q and 10-K,
including a "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and, with respect to the annual consolidated financial
statements only, a report thereon by the Company's independent auditors.

EVENTS OF DEFAULT AND REMEDIES
 
     The Indenture provides that each of the following constitutes an Event of
Default; (i) default for 30 days in the payment when due of interest on the
Notes; (ii) default in payment when due of principal on the Notes; (iii) failure
by the Company to comply with the provisions described above under
"-- Repurchase at the Option of Holders"; (iv) failure by the Company for 60
days after the receipt of written notice to comply with certain other covenants
and agreements contained in the Indenture or the Notes; (v) default under any
mortgage, indenture or instrument under which there may be issued or by which
there may be secured or evidenced any Indebtedness for money borrowed by the
Company or any of its Material Subsidiaries (or the payment of which is
guaranteed by the Company or any of its Material Subsidiaries), whether such
Indebtedness or guarantee now exists or is created after the date on which the
Notes are first authenticated and issued, which default (a) is caused by a
failure to pay when due principal or interest on such Indebtedness within the
grace period provided in such Indebtedness (which failure continues beyond any
applicable grace period) (a "Payment Default") or (b) results in the
acceleration of such Indebtedness prior to its express maturity without such
acceleration being rescinded or annulled 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 million or more; (vi) failure by
the Company or any Material Subsidiary of the Company to pay final
non-appealable judgments (other than any judgment as to which a reputable
insurance company has accepted full liability) aggregating in excess of $5
million, which judgments are not stayed within 60 days after their entry; and
(vii) certain events of bankruptcy or insolvency with respect to the Company or
any of its Material Subsidiaries.
 
     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. Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency, with respect to the Company or any Material
Subsidiary, all outstanding Notes will become due and payable without further
action or notice. Holders of the Notes may not enforce the Indenture or the
Notes except as provided in the Indenture. Subject to certain limitations,
holders of a majority in principal amount of the then outstanding Notes may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from holders of the Notes 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.
 
     By notice to the Trustee, the holders of a majority in aggregate principal
amount of the Notes then outstanding may, on behalf of the holders of all of the
Notes, 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
the Designated Event Payment or interest on, or the principal of, the Notes.
 
     The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company 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.
 
TRANSFER AND EXCHANGE
 
     The Company has initially appointed the Trustee as Registrar in Chicago,
Illinois. The Company reserves the right to vary or terminate the appointment of
the Registrar or to appoint additional or other Registrars or to approve any
change in the office through which the Registrar acts.
 
     A holder may transfer or exchange Notes in accordance with the Indenture.
The Registrar may require a holder, among other things, to furnish appropriate
endorsements and transfer documents and the Company may require a holder to pay
any taxes and fees required by law or permitted by the Indenture. The Company is
not required to exchange or register the transfer of any Note selected for
redemption. Also, the Company is not required to exchange or register the
transfer of any Note for a period of 15 days before a selection of Notes to be
redeemed.
 
                                       24
<PAGE>   28
 
     The registered holder of a Note is treated as the owner of it for all
purposes.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
     Except as provided in the next succeeding paragraph, the Indenture or the
Notes may be amended or supplemented with the consent of the holders of at least
a majority in principal amount of the then outstanding Notes (including consents
obtained in connection with a 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 consents obtained in connection with a
tender offer or exchange offer for Notes).
 
     Without the consent of each holder affected, an amendment or waiver may not
(with respect to any Notes held by a nonconsenting holder of Notes) (i) reduce
the amount of Notes whose holders must consent to an amendment, supplement or
waiver, (ii) reduce the principal of or change the fixed maturity of any Note or
alter the provisions with respect to the redemption of the Notes, (iii) reduce
the rate of or change the time for payment of interest on any Note, (iv) waive a
default in the payment of principal of or interest on any 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), (v) make any Note payable in money other than
that stated in the Notes, (vi) make any change in the provisions of the
Indenture relating to waivers of past Defaults or the rights of holders of Notes
to receive payments of principal of or interest on the Notes, (vii) waive a
redemption payment with respect to any Note, (viii) impair the right to convert
the Notes into Common Stock, (ix) modify the conversion provisions of the
Indenture in a manner adverse to the holders of the Notes or (x) make any change
in the foregoing amendment and waiver provisions.
 
     Notwithstanding the foregoing, without the consent of any holder of Notes,
the Company and the Trustee may amend or supplement the Indenture 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 Company's obligations to holders of the Notes in the case of a
merger or consolidation, 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 under the Indenture of any such holder, or to comply with
requirements of the Commission in order to qualify, or maintain the
qualification of, the Indenture under the Trust Indenture Act.
 
NOTICES
 
     Notice to holders of the Notes will be given by mail to the addresses of
such holders as they appear in the Register (as such term is defined in the
Indenture). Such notices will be deemed to have been given on the date of such
mailing.
 
CONCERNING THE TRUSTEE
 
     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee are 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 Trustee is the lender under the Company's Credit Agreement.
 
     The holders of a majority in principal amount of the then outstanding Notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that, in case an Event of Default
shall occur (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 Notes, unless such holder shall have the offered to the
Trustee security and indemnity satisfactory to it against any loss, liability or
expense.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
     The following is a general discussion of the principal United States
federal income tax considerations relevant to purchasers of the Notes from the
Selling Security Holders pursuant to the offering. This discussion is based on
currently existing provisions of the Internal Revenue Code of 1986, as amended
(the "Code"), existing and proposed Treasury regulations promulgated thereunder
and administrative and judicial interpretations thereof, all as in effect or
proposed on the date hereof and all of which are subject to change, possibly
with retroactive effect, or different interpretations.
 
     This discussion does not deal with all aspects of United States federal
income taxation that may be important to holders of the Notes or shares of the
Common Stock received upon conversion thereof, and it does not include any
description of the tax laws of any state, local or foreign government. This
discussion does not address the tax consequences to subsequent beneficial owners
of the Notes, and is limited to beneficial owners who hold the Notes and the
shares of Common Stock received upon conversion thereof as capital assets within
the meaning of Section 1221 of the Code. Moreover, this discussion is for
general information only and does not purport to address all of the United
States federal income tax consequences that may be relevant to particular
purchasers (such as certain financial institutions, insurance companies,
tax-exempt entities, dealers in securities or persons who have hedged the risk
of owning a Note or a share of Common Stock) that may be subject to special
rules.
 
     For the purpose of this discussion, a "United States Holder" refers to a
beneficial owner of a Note who or which is (i) a citizen or resident of the
United States for United States federal income tax purposes, (ii) a corporation,
partnership or other entity created or organized in or under the laws of the
United States or of any political subdivision thereof (iii) any other person who
is subject to United States federal income tax on a net income basis in respect
of the Notes, or (iv) a trust if, and only if, (A) a court within the United
States is able to exercise primary supervision over the administration of the
trust and (B) one or more U.S. persons have the authority to control all
substantial decisions of the trust. The term "Non-United States Holder" refers
to any beneficial owner of a Note who or which is not a United States Holder.
 
     PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO
THE PARTICULAR FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE
ACQUISITION, OWNERSHIP AND DISPOSITION OF THE NOTES, INCLUDING THE CONVERSION OF
THE NOTES INTO SHARES OF COMMON STOCK, AND THE EFFECT THAT THEIR PARTICULAR
CIRCUMSTANCES MAY HAVE ON SUCH TAX CONSEQUENCES.
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS APPLICABLE TO UNITED STATES HOLDERS
 
     Interest on Notes. Interest paid on the Notes will be taxable to a United
States Holder as ordinary interest income in accordance with such holder's
method of tax accounting.
 
     Original Issue Discount. In general, a debt instrument has original issue
discount ("OID") to the extent that its "stated redemption price at maturity"
exceeds its "issue price." A Note's "redemption price" at
 
                                       27
<PAGE>   31
 
maturity is its principal (face) amount. The "issue price" of the Notes will be
equal to the initial offering price to the public (not including any bond house,
broker or similar person or organization acting in the capacity of an
underwriter, placement agent or wholesaler) at which a substantial amount of the
Notes are sold. However, if the OID with respect to a debt instrument is less
than one-fourth of one percent of the stated redemption price at maturity
multiplied by the number of full years from the issue date to the maturity date,
then the amount of OID shall be considered zero.
 
     The Company expects that the Notes will not be sold by the Selling Security
Holders with OID. However, if it is determined that the Notes have OID, a United
States Holder will be required to include in gross income for United States
federal income tax purposes an amount equal to the sum of the "daily portions"
of such OID for all days during the taxable year on which the holder holds the
debt instrument. The daily portions of OID required to be included in a holder's
gross income in a taxable year will be determined on a constant yield basis by
allocating to each day during the taxable year on which the holder holds the
debt instrument a pro rata portion of the OID on such debt instrument which is
attributable to the "accrual period" in which such day is included. Accrual
periods with respect to a Note may be any set of periods (which may be of
varying lengths) selected by a United States Holder as long as (i) no accrual
period is longer than one year and (ii) each scheduled payment of interest or
principal on the Note occurs on either the first or final day of an accrual
period. The amount of OID attributable to each "accrual period" will be equal to
the product of (i) the "adjusted issue price" at the beginning of such accrual
period and (ii) the "yield to maturity" of the debt instrument stated in a
manner appropriately taking into account the length of the accrual period. The
"yield to maturity" is the discount rate that, when used in computing the
present value of all payments to be made under the Notes, produces an amount
equal to the issue price of the Notes. The "adjusted issue price" of a Note at
the beginning of an accrual period is generally defined as the issue price of
the Note plus the aggregate amount of OID that accrued in all prior accrual
periods, less any cash payments on the Note. Accordingly, a United States Holder
of a Note will be required to include OID thereon in gross income for United
States federal tax purposes in advance of the receipt of cash in respect of such
income. The amount of OID allocable to an initial short accrual period may be
computed using any reasonable method if all other accrual periods, other than a
final short accrual period, are of equal length. The amount of OID allocable to
the final accrual period at maturity of a Note is the difference between (x) the
amount payable at the maturity of the Note and (y) the Note's adjusted issue
price as of the beginning of the final accrual period.
 
     Upon the occurrence of a Designated Event, each holder of Notes shall have
the right to require the Company to repurchase all or any part of such holder's
Notes at a purchase price equal to 100% of the principal amount thereof,
together with accrued and unpaid interest thereon to the Designated Event
Payment Date. Computation of the yield and maturity of the Notes is not affected
by such redemption rights and obligations if, based on all the facts and
circumstances as of the issue date, the stated payment schedule of the Notes is
significantly more likely than not to occur. The Company has determined that,
based on all of the facts and circumstances as of the issue date, it is
significantly more likely than not that the Notes will be paid according to
their stated schedule.
 
     The Company may redeem the Notes, in whole or in part, at any time on or
after April 19, 2001 at redemption prices specified elsewhere herein plus
accrued and unpaid interest, if any, on the Notes so redeemed to but excluding
the date of redemption. The Regulations contain rules for determining the
"maturity date" and the stated redemption price at maturity of an instrument
that may be redeemed prior to its stated maturity date at the option of the
issuer. Under the Regulations, solely for purposes of the accrual of OID, it is
assumed that the issuer will exercise any option to redeem a debt instrument if
such exercise will lower the yield-to-maturity of the debt instrument. The
Company believes that it will not be presumed to redeem the Notes prior to their
stated maturity under these rules because the exercise of such option would not
lower the yield-to-maturity of the Notes.
 
     Constructive Dividend. Certain corporate transactions, such as
distributions of assets to holders of Common Stock, may cause a deemed
distribution to the holders of the Notes if the conversion price or conversion
ratio of the Notes is adjusted to reflect such corporate transaction. Such
deemed distributions will be taxable as a dividend, return of capital, or
capital gain in accordance with the earnings and profits rules discussed under
"Dividends on Shares of Common Stock."
                                       28
<PAGE>   32
 
     Sale or Exchange of Notes or Shares of Common Stock. In general, a United
States Holder of Notes will recognize gain or loss upon the sale, redemption,
retirement or other disposition of the Notes measured by the difference between
(i) the amount of cash and the fair market value of any property received
(except to the extent attributable to the payment accrued interest) and (ii) the
United States Holder's tax basis in the Notes. A United States Holder's tax
basis in Notes generally will equal the cost of the Notes to the holder. In
general, each United States Holder of Common Stock into which the Notes have
been converted will recognize gain or loss upon the sale, exchange, redemption,
or other disposition of the Common Stock under rules similar to those applicable
to the Notes. Special rules may apply to redemptions of the Common Stock which
may result in the amount paid being treated as a dividend. Assuming the
requirements of Section 1221 of the Code are satisfied, the gain or loss on the
disposition of the Notes or shares of Common Stock will be capital gain or loss
and will be taxable at various preferential rates depending on the extent to
which a United States Holder's holding period for the notes or shares of Common
Stock exceeds one year. (For the basis and holding period of shares of Common
Stock, see "-- Conversion of Notes.")
 
     Conversion of Notes. A United States Holder of Notes generally will not
recognize gain or loss on the conversion of the Notes solely into shares of
Common Stock. The United States Holder's tax basis in the shares of Common Stock
received upon conversion of the Notes will be equal to the holder's aggregate
basis in the Notes exchanged therefor (less any portion thereof allocable to
cash received in lieu of a fractional share). The holding period of the shares
of Common Stock received by the holder upon conversion of Notes will generally
include the period during which the holder held the Notes prior to the
conversion.
 
     Cash received in lieu of a fractional share of Common Stock should be
treated as a payment in exchange for such fractional share rather than as a
dividend. Gain or loss recognized on the receipt of cash paid in lieu of such
fractional shares generally will equal the difference between the amount of cash
received and the amount of tax basis allocable to the fractional shares.
 
     Dividends on Shares of Common Stock. Distributions on shares of Common
Stock will constitute dividends for United States federal income tax purposes to
the extent of current or accumulated earnings and profits of the Company as
determined under United States federal income tax principles. Dividends paid to
holders that are United States corporations may qualify for the
dividends-received deduction.
 
     To the extent, if any, that a United States Holder receives distributions
on shares of Common Stock that would otherwise constitute dividends for United
States federal income tax purposes but that exceed current and accumulated
earnings and profits of the Company, such distributions will be treated first as
a non-taxable return of capital reducing the holder's basis in the shares of
Common Stock. Any such distributions in excess of the holder's basis in the
shares of Common Stock will be treated as capital gain.
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS APPLICABLE TO NON-UNITED STATES
HOLDERS
 
     The following summary describes certain United States federal income and
estate tax consequences of the ownership of Notes as of the date hereof by a
Non-United States Holder.
 
     Under present United States federal income and estate tax law, and subject
to the discussion below concerning backup withholding:
 
     Interest and OID on Notes. Generally interest paid on the Notes (including
OID) to a Non-United States Holder will not be subject to United States income
tax and no withholding of United States federal income tax will be required with
respect to the payment by the Company or any Paying Agent of principal or
interest (including OID) on a Note owned by a Non-United States Holder, provided
(i) that the beneficial owner does not actually or constructively own 10% or
more of the total combined voting power of all classes of stock of the Company
entitled to vote within the meaning of section 871(h)(3) of the Code and the
regulations thereunder, (ii) the beneficial owner is not a "controlled foreign
corporation" (as defined in Section 957 of the Code) that is related directly,
indirectly or constructively to the Company through stock ownership and (iii)
the beneficial owner satisfies the statement requirement (described generally
below) set forth in section 871(h) and section 881(c) of the Code and the
regulations thereunder.
 
                                       29
<PAGE>   33
 
     To satisfy the requirement referred to in (a)(iii) above (the "Portfolio
Interest Exception"), the beneficial owner of such Note, or a financial
institution holding the Note on behalf of such owner, must provide, in
accordance with specified procedures, the Company or the Paying Agent with a
statement to the effect that the beneficial owner is not a United States person.
Pursuant to current temporary Regulations, these requirements will be met if (1)
the beneficial owner provides the payor his name and address, and certifies,
under penalties of perjury, that he is not a United States person (which
certification may be made on an Internal Revenue Service Form W-8 (or successor
or substitute form)) or (2) a financial institution that holds customer's
securities in the ordinary course of its trade or business and holds the Note on
behalf of the beneficial owner certifies, under penalties of perjury, that such
statement has been received by it (or by another financial institution acting on
behalf of the Non-United States Holder), and furnishes the Paying Agent with a
copy thereof.
 
     Regulations recently issued by the Internal Revenue Service, which will be
effective for payments made after December 31, 1998 (subject to certain
transition rules), made modifications to the certification procedures applicable
to Non-United States Holders. In general, these regulations unify certification
procedures and forms and clarify and modify reliance standards. A Non-United
States Holder should consult its own advisor regarding the effect of the new
Regulations.
 
     If a Non-United States Holder cannot satisfy the requirements of the
Portfolio Interest Exception, payments of interest (including OID) made to
Non-United States Holders will generally be subject to a 30% withholding tax, or
such lower rate as may be specified by an applicable income tax treaty, unless
the beneficial owner of the Note provides the Company or the Paying Agent, as
the case may be, with a properly executed (1) Internal Revenue Service Form 1001
(or successor form) claiming an exemption from withholding under the benefit of
a tax treaty or (2) Internal Revenue Service Form 4224 (or successor form)
stating that interest (including OID) paid on the Note is not subject to
withholding tax because it is effectively connected with the beneficial owner's
conduct of a trade or business in the United States.
 
     If a Non-United States Holder is engaged in a trade or business in the
United States and interest (including OID) on the Note is effectively connected
with the conduct of such trade or business, the Non-United States Holder,
although exempt from the withholding tax discussed above, will generally be
subject to United States federal income tax on such interest (including OID) on
a net income basis in the same manner as if it were a United States person. In
addition, if such holder is a foreign corporation, it may be subject to a branch
profits tax equal to 30% of its effectively connected earnings and profits for
the taxable year, or such lower rate as may be specified by an applicable income
tax treaty, subject to adjustments.
 
     Sale or Exchange of Notes or Shares of Common Stock. A Non-United States
Holder generally will not be subject to United States federal income tax on gain
realized upon the sale or other disposition of the Notes or shares of Common
Stock unless (i) such gain or income is effectively connected with a trade or
business in the United States of the Non-United States Holder, or (ii) in the
case of a Non-United States Holder who is a nonresident alien individual, such
Holder is present in the United States for 193 days or more in the taxable year
of such sale, exchange or retirement, and certain other conditions apply.
 
     Conversion of Notes. A Non-United States Holder generally will not be
subject to United States federal income tax on the conversion of a Note into
shares of Common Stock. To the extent a Non-United States Holder receives cash
in lieu of a fractional share on conversion, such cash may give rise to gain
that would be subject to the rules described above with respect to the sale or
exchange of a Note or Common Stock.
 
     Dividends on Shares of Common Stock. Generally, any distribution on shares
of Common Stock to a Non-United States Holder will be subject to United States
federal income tax withholding at a rate of 30% unless the dividend is
effectively connected with the conduct of a trade or business within the United
States by the Non-United States Holder, in which case the dividend will be
subject to the United States federal income tax on net income that applies to
United States persons generally (and, with respect to corporate Holders and
under certain circumstances, the branch profits tax). Non-United States Holders
should consult any applicable income tax treaties, which may provide for a lower
rate of withholding or other rules different from those described above. A
NonUnited States Holder may be required to satisfy certain certification
requirements in order to claim a reduction of or exemption from withholding
under the foregoing rules.

     Estate Tax Consideration. A Note beneficially owned by an individual who at
the time of death is a Non-United States Holder generally will not be includible
in the individual's gross estate for the purposes of the United States federal
estate tax as a result of such individual's death, provided that such individual
does not at the time of death actually or constructively own 10% or more of the
total combined voting power of all classes of stock of the Company entitled to
vote within the meaning of section 871(h)(3) of the Code and provided that the
interest payments with respect to such Note will not have been, if received at
the time of such individual's death, effectively connected with the conduct of a
United States trade or business by such individual.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     The "backup" withholding and information reporting requirements may apply
to certain payments of principal and interest (including OID) on a Note and to
certain payments or proceeds of the sale or retirement of a Note. The Company,
its agent, a broker, the Trustee or the Paying Agent, as the case may be, is
required to withhold tax from any payment that is subject to backup withholding
at a rate of 31% of such payment if the holder fails to furnish his taxpayer
identification number (social security number or employee identification
number), to certify that such holder is not subject to backup withholding, or to
otherwise comply with the applicable requirements of the backup withholding
rules. Certain holders (including, among others, all corporations) are not
subject to the backup withholding and reporting requirements.
 
     Under current Treasury Regulations, backup withholding and information
reporting do not apply to payments made by the Company or any agent thereof (in
its capacity as such) to a holder of a Note who has provided the required
certification under penalties of perjury that it is not United States Holder or
has otherwise established an exemption (provided that neither the Company nor
such agent has actual knowledge that the holder is a United States Holder or
that the conditions of any other exemption are not in fact satisfied). Payments
of the proceeds from the sale by a holder who is not a United States Holder of a
Note made to or through a foreign office of a broker will not be subject to
United States information reporting or backup withholding, except that if the
broker is a United States person, a controlled foreign corporation for U.S. tax
purposes or a foreign person 50% or more of whose gross income is effectively
connected with a United States trade or business for a specified three-year
period, United States information reporting may apply to such payments.
 
     Payments of the proceeds from the sale of a Note to or through the United
States office of a broker is subject to United States information reporting and
backup withholding unless the holder or beneficial owner certifies as to its
non-United States status or otherwise establishes an exemption from United
States information reporting and backup withholding.
 
     In October 1997, Regulations were issued which alter the foregoing rules in
certain respects and which generally will apply to any payments (including OID)
in respect of a Note or proceeds from the sale of a Note that are made after
December 31, 1998. Among other things, such regulations expand the number of
foreign intermediaries that are potentially subject to information reporting and
address certain documentary evidence requirements relating to exemption from the
general backup withholding requirements. Holders of the Notes should consult
their tax advisors concerning possible application of the final regulations to
amounts of OID that they are required to include as well as the possible
application of such regulation to any payments made on or with respect to the
Notes.
 
     Any amounts withheld under the backup withholding rules from a payment to a
holder may be claimed as a credit against such holder's United States federal
income tax liability.
 
     The Company is required to furnish certain information to the Internal
Revenue Service, and will furnish annually to record holders of Notes,
information with respect to interest and OID, if any, accruing during the
calendar year. The OID information will be based upon the issue price of the
debt instrument as if the holder were the original holder of the debt
instrument. No assurance can be given that the Internal Revenue Service will not
challenge the accuracy of the reported information. Subsequent holders who
purchase Notes for an amount other than the adjusted issue price and/or on a
date other than the last day of an accrual period will be
 
                                       31

required to determine for themselves the amount of OID, if any, they are
required to include in gross income for United States federal income tax
purposes.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Company's Amended and Restated Certificate of Incorporation provides
for indemnification to the full extent permitted by the laws of the State of
Delaware against and with respect to threatened, pending or completed actions,
suits or proceedings arising from or alleged to arise from, a party's actions or
omissions as a director, officer, employee or agent of the Company or of any
other corporation, partnership, joint venture, trust or other enterprise which
has served in such capacity at the request of the Company if such acts or
omissions occurred or were or are alleged to have occurred, while said party was
a director or officer of the Company; provided, however, the Company shall not
indemnify any director or officer in an action against the Company unless the
Company shall have consented to such action. Generally, under Delaware law,
indemnification will only be available where an officer or director can
establish that he/she acted in good faith and in a manner which was reasonably
believed to be in or not opposed to the best interests of the Company.
 
     Section 145 of the Delaware Law provides that a corporation may indemnify a
director, officer, employee or agent made a party to an action by reason of the
fact that such person was a director, officer, employee or agent of the
corporation or was serving at the request of the corporation against expenses
actually incurred by such person in connection with such action if such person
acted in good faith and in a manner such person reasonably believed to be in, or
not opposed to, the best interest of the corporation with respect to any
criminal action, and had no reasonable cause to believe his conduct was
unlawful. Delaware Law does not permit a corporation to eliminate a director's
duty of care, and the provisions of the Company's Amended and Restated
Certificate of Incorporation have no effect on the availability of equitable
remedies such as injunction or rescission, based upon a director's breach of the
duty of care. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers or persons controlling
the Company pursuant to the foregoing provisions and agreements, the Company has
been informed that in the opinion of the Staff of the Securities and Exchange
Commission such indemnification is against policy as expressed in the Securities
Act and is therefore unenforceable.
 
     The Company maintains a director's and officer's liability insurance policy
which indemnifies directors and officers for certain losses arising from a claim
by reason of a wrongful act, as defined, under certain circumstances where the
Company does not provide indemnification.

ITEM 17. UNDERTAKINGS
 
The undersigned Registrant hereby undertakes:
 
     (1) to file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
 
          (i) To include any prospectus required by Section 10(a) (3) of the
     Securities Act of 1933;
 
          (ii) To reflect in the prospectus any facts or events arising after
     the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement; notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in the volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set forth in the "Calculation of Registration Fee" table in the
     effective registration statement.
 
          (iii) To include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement:
 
     Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained in
the periodic reports filed by the Registrant pursuant to Section 13 or Section
15(d) of the Securities Exchange Act of 1934 that are incorporated by reference
in the registration statement.
 
     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be 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.
 
     (4) That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the Registrant's annual report pursuant to Section
13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by
reference in this Registration Statement shall be deemed to be a new
Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
     (5) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

Smith Barney Inc.
388 Greenwich Street
New York, New York  10013


Ladies and Gentlemen:

         Sabratek Corporation, a Delaware corporation (the "Company"), proposes
to issue and sell to the parties named in Schedule I hereto (the "Initial
Purchasers"), for whom you are acting as representative (the "Representative"),
$85,000,000 principal amount of its 6% Convertible Notes Due 2005 (the "Firm
Securities"). The Securities are convertible into shares of common stock of the
Company, par value $0.01 per share (the "Common Stock"), at the conversion price
set forth herein. The Company also proposes to grant to the Initial Purchasers
an option to purchase up to $12,750,000 additional principal amount of such
Notes to cover over-allotments, if any (the "Option Securities" and, together
with the Firm Securities, the "Securities"). The Securities are to be issued
under an indenture (the "Indenture") to be dated as of April 14, 1998, between
the Company and LaSalle National Bank, as trustee (the "Trustee"). If you are
the only Initial Purchasers, all references herein to the Representative shall
be deemed to be to the Initial Purchasers.

         The sale of the Securities to the Initial Purchasers will be made
without registration of the Securities or the Common Stock issuable upon
conversion thereof under the Securities Act of 1933, as amended (the "Act"). You
have advised the Company that the Initial Purchasers will make an offering of
the Securities purchased by them hereunder in accordance with Section 4 hereof,
as soon as you deem advisable.

         In connection with the sale of the Securities, the Company has prepared
an offering memorandum, dated April 8,1998 (the "Offering Memorandum"). The
Offering Memorandum sets forth certain information concerning the Company, the
Securities and the 

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

(1) Plus an option to purchase up to $12,750,000 additional principal amount of 
    such Notes to cover over-allotments.
<PAGE>   2




Common Stock issuable upon conversion thereof. The Company hereby confirms that
it has authorized the use of the Offering Memorandum in connection with the
offering and resale of the Securities by the Initial Purchasers. Any references
herein to the Offering Memorandum shall be deemed to include all exhibits
thereto and all documents incorporated by reference therein that were filed
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), on
or before the date and time that this Agreement is executed and delivered by the
parties hereto (the "Execution Time"); and any reference herein to the terms
"amend", "amendment" or "supplement" with respect to the Offering Memorandum
shall be deemed to refer to and include the filing of any document under the
Exchange Act after the Execution Time that is incorporated by reference therein.

         The holders of the Securities or the Common Stock issuable upon
conversion thereof will be entitled to the benefits of the Registration
Agreement to be dated April 14, 1998, between the Company and the Initial
Purchasers (the "Registration Agreement"), substantially in the form of Exhibit
C hereto.

         1.   Representations and Warranties. The Company represents and 
warrants to, and agrees with, each Initial Purchaser as set forth below in this
Section 1.

         (a)  The Offering Memorandum as of its date did not, and (as the same
    may have been amended or supplemented) as of the Closing Date will not,
    contain any 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; provided, however,
    that the Company makes no representations or warranties as to the
    information contained in or omitted from the Offering Memorandum in reliance
    upon and in conformity with information furnished in writing to the Company
    by or on behalf of the Initial Purchasers through the Representative
    specifically for inclusion in the Offering Memorandum (and any amendment or
    supplement thereof or thereto). All documents incorporated by reference in
    the Offering Memorandum that were filed under the Exchange Act on or before
    the Execution Time complied, and all such documents that are filed under the
    Exchange Act after the Execution Time and on or before the Closing Date will
    comply, in all material respects with the applicable requirements of the
    Exchange Act and the rules thereunder in effect as of the date of filing.

         (b)  The Company has not taken and will not take, directly or

         (c) Neither the Company, nor to the knowledge of the Company any of its
    Affiliates (as defined in Rule 501(b) of Regulation D under the Act
    ("Regulation D")), nor any person acting on its or the knowledge of the
    Company on the behalf of any of its

                                      2
<PAGE>   3




    Affiliates (other than the Initial Purchasers, as to whom the Company makes
    no representation) has directly or indirectly (i) made offers or sales of
    any security, or solicited offers to buy any security, under circumstances
    that would require the registration of the Securities or the Common Stock
    issuable upon conversion thereof under the Act or (ii) engaged in any form
    of general solicitation or general advertising (within the meaning of
    Regulation D) in connection with any offer or sale of the Securities in the
    United States.

         (d)  Assuming compliance by each of the Initial Purchasers with their
    agreements and the accuracy of their representations contained herein, it is
    not necessary in connection with the offer, sale and delivery of the
    Securities or the Common Stock issuable upon conversion thereof in the
    manner contemplated by this Agreement and the Offering Memorandum to
    register the Securities or such Common Stock under the Act or to qualify the
    Indenture under the Trust Indenture Act of 1939, as amended (the "Trust
    Indenture Act").

         (e)  None of the Company or any person acting on behalf of the Company,
    or to the knowledge of the Company its Affiliates or any person acting on
    behalf of its Affiliates (other than the Initial Purchasers, as to whom the
    Company makes no representation) has engaged in any directed selling efforts
    (as that term is defined in Regulation S under the Act ("Regulation S"))
    with respect to the Securities or the Common Stock issuable upon conversion
    thereof, and each of the Company, its Affiliates and any person acting on
    its or their behalf has complied with the offering restrictions requirement
    of Regulation S.

         (f)  The Company is subject to the reporting requirements of Section 13
    or Section 15(d) of the Exchange Act and has timely filed all reports
    required to be filed thereunder within the last 12 months.

         (g)  The Securities satisfy the requirements set forth in Rule
    144A(d)(3) under the Act.

         (h)  The Company has agreed to permit the Securities to be designated
    PORTAL eligible securities, will pay the requisite fees related thereto and
    has been advised by the National Association of Securities Dealers, Inc.
    PORTAL Market that as of the Closing Date the Securities will have been
    designated PORTAL eligible securities in accordance with the rules and
    regulations of the National Association of Securities Dealers, Inc.

         (i)  The Company is not an "investment company" within the meaning of
    the Investment Company Act of 1940, as amended (the "Investment Company
    Act"), without 


                                      3
<PAGE>   4



    taking account of any exemption arising out of the number of holders of the
    Company's securities, and, if the Company conducts its business as set forth
    in the Offering Memorandum and complies with the covenants binding upon it
    under the Indenture, will not become an "investment company" and will not be
    required to be registered under the Investment Company Act.

         (j)  The Company has not paid or agreed to pay to any person any
    compensation for soliciting another to purchase any securities of the
    Company (except as contemplated by this Agreement).

         (k)  The information provided by the Company pursuant to Section 5(g)
    hereof will not, at the date thereof, contain any 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.

         (l)  Except with respect to the credit agreement dated March 26, 1997 
    by and between the Company and LaSalle National Bank NI (with respect to
    which the Company shall receive a waiver prior to closing), neither the
    issue and sale of the Securities (assuming compliance by the Company and the
    Initial Purchasers with their covenants set forth in this Agreement), the
    execution and delivery of the Indenture and the Registration Agreement, the
    consummation of any other of the transactions contemplated in this Agreement
    or the Registration Agreement nor the fulfillment of the terms of this
    Agreement or the Registration Agreement will conflict with, result in a
    breach or violation of, or constitute a default under any law or the
    Certificate of Incorporation or by-laws of the Company or the terms of any
    indenture or other agreement or instrument to which the Company or any of
    its subsidiaries is a party or bound, or any judgment, order or decree
    applicable to the Company or any of the Company's subsidiaries of any court,
    regulatory body, administrative agency or governmental body having
    jurisdiction over the Company or any of the Company's subsidiaries, which
    breach, violation or default is reasonably likely to have a material adverse
    effect on the financial condition, earnings, business or properties of the
    Company and its subsidiaries on a consolidated basis (a "Material Adverse
    Effect").

         (m)  The Indenture has been duly authorized, executed and delivered, 
    and constitutes a legal, valid and binding instrument enforceable against
    the Company in accordance with its terms (subject, as to enforcement of
    remedies, to applicable bankruptcy, reorganization, insolvency, moratorium
    or other laws affecting creditors' rights generally from time to time in
    effect and assuming that the Indenture has been duly authorized, executed
    and delivered by, and is a valid and binding agreement of the Trustee); and
    the Securities have been duly authorized and, when executed and
    authenticated in accordance with the provisions of the Indenture and
    delivered to and

                                      4
<PAGE>   5



    paid for by the Initial Purchasers pursuant to this Agreement, will
    constitute legal, valid and binding obligations of the Company entitled to
    the benefits of the Indenture; and the Notes will comply in all material
    respects with the description thereof set forth under the heading
    "Description of Notes" in the Offering Memorandum, insofar as such
    statements purport to summarize certain provisions of the Securities and the
    Indenture, provide a fair summary of such provisions.

         (n)  The shares of Common Stock issuable upon conversion the Securities
    have been duly authorized for issuance, and when issued upon conversion of
    the Securities in accordance with the terms of such Securities will be
    validly issued, fully paid and nonassessable; and the capital stock of the
    Company conforms in all material respects to the description thereof
    contained in the Offering Memorandum.

         (o)  This Agreement and the Registration Agreement have been duly
    authorized, executed and delivered by the Company.

         (p)  Each "significant subsidiary" (as defined in Rule 1-02(w) of
    Regulation S-X under the Act and the Exchange Act) of the Company is listed
    in Schedule II hereto.

         2.   Purchase and Sale. (a) Subject to the terms and conditions and in
reliance upon the representations and warranties herein set forth, the Company
agrees to sell to each Initial Purchaser, and each Initial Purchaser agrees,
severally and not jointly, to purchase from the Company, at a purchase price of
96.75% of the principal amount thereof, plus accrued interest, if any, from
April 14, 1998 to the Closing Date, the principal amount of the Firm Securities
set forth opposite such Initial Purchaser's name in Schedule I hereto. Each
Security will be convertible at the option of the holder into shares of Common
Stock at a conversion price of $40.46 ("Conversion Price"), which Conversion
Price is subject to adjustment in certain events, as provided in the Indenture.

         (b)  Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, the Company hereby grants an
option (the "Option") to the Initial Purchasers to purchase, severally and not
jointly, the Option Securities at a purchase price of 96.75% of the principal
amount thereof, plus accrued interest, if any, from April 14, 1998, to the
settlement date for the Option Securities. The Option may be exercised only to
cover over-allotments in the sale of the Firm Securities by the Initial
Purchasers. The Option may be exercised in whole or in part at any time (but not
more than once) on or before the 30th day after the date of the Offering
Memorandum upon written or telegraphic notice by the Representative to the
Company setting forth the principal amount of Option Securities as to which the
Initial Purchasers are exercising the Option and the settlement date therefor.
Delivery of certificates for the Option Securities, and payment therefor, shall
be made as provided in Section 3 hereof. The principal amount of Option
Securities to be purchased by each Initial


                                      5
<PAGE>   6





Purchaser shall be the same percentage of the total principal amount of Option
Securities to be purchased by the Initial Purchasers as such Initial Purchaser
is purchasing of the Firm Securities, subject to such adjustments as the
Representative shall deem advisable.

         3.   Delivery and Payment. Delivery of and payment for the Firm
Securities and Option Securities (if the Option provided for in Section 2(b)
hereof shall have been exercised on or before the first business day prior to
the Closing Date) shall be made at 10:00 AM, New York City time, on April 14,
1998, or such later date (not later than April 21, 1998) as the Representative
shall designate, which date and time may be postponed by agreement between the
Representative and the Company or as provided in Section 9 hereof (such date and
time of delivery and payment for the Securities being herein called the "Closing
Date"). Delivery of the Securities shall be made to the Representative for the
respective accounts of the Initial Purchasers against payment by the Initial
Purchasers through the Representative of the purchase price thereof to the
Company by wire transfer of same day funds to such account as the Company shall
designate at least two business days in advance of the Closing Date. Delivery of
the Securities shall be made at such location as the Representative shall
reasonably designate at least one business day in advance of the Closing Date
and payment for the Securities shall be made at the office of Ross & Hardies
("Counsel for the Company), 150 North Michigan Avenue, Suite 2500, Chicago,
Illinois 60601. Certificates for the Securities shall be registered in such
names and in such denominations as the Representative may request not less than
one full business day in advance of the Closing Date.

         The Company agrees, if so requested by the Representative, to have the
Securities available for inspection, checking and packaging by the
Representative in New York, New York, not later than 1:00 PM on the business day
prior to the Closing Date.

         If the Option is exercised after the first business day prior to the
Closing Date, the Company will deliver (at the expense of the Company) to the
Representative, at 388 Greenwich Street, New York, New York, on the date
specified by the Representative (which shall be within three business days after
exercise of the Option), certificates for the Option Securities in such names
and denominations as the Representative shall have requested against payment of
the purchase price thereof by wire transfer of same day funds to such account as
the Company shall designate at least two business days in advance of the date on
which such payment is required to be made. If settlement for the Option
Securities occurs after the Closing Date, the Company will deliver to the
Representative on the settlement date for the Option Securities, and the
obligation of the Initial Purchasers to purchase the Option Securities shall be
conditioned upon receipt of, supplemental opinions, certificates and letters
confirming as of such date the opinions, certificates and letters delivered on
the Closing Date pursuant to Section 6 hereof.

         4.   Offering of Securities; Restrictions on Transfer. Each Initial
Purchaser, severally and not jointly, represents and warrants to and agrees with
the Company that:


                                      6
<PAGE>   7





         (a)  It has not offered or sold, and will not offer or sell, any
    Securities except (i) to persons it reasonably believes to be qualified
    institutional buyers (as defined in Rule 144A under the Act) and that, in
    connection with each such sale, it has taken or will take reasonable steps
    to ensure that the purchaser of such Securities is aware that such sale is
    being made in reliance on Rule 144A or (ii) in accordance with the
    restrictions set forth in Exhibit A hereto.

         (b)  It is an institution which is an "accredited investor" within the
    meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act.

         (c)  Neither it nor any person acting on its behalf has made or will
    make offers or sales of the Securities in the United States by means of any
    form of general solicitation or general advertising (within the meaning of
    Regulation D) in the United States.

         5.   Agreements. The Company agrees with each Initial Purchaser that:

         (a)  The Company will furnish to each Initial Purchaser and Mayer, 
    Brown & Platt ("Counsel for the Initial Purchasers"), without charge, during
    the period mentioned in paragraph (b) below, as many copies of the Offering
    Memorandum and any supplements and amendments thereof or thereto as they may
    reasonably request. The Company will pay the expenses of printing or other
    production of all documents relating to the offering.

         (b)  Prior to the completion of the distribution of the Securities by
    the Initial Purchasers (as determined by the Initial Purchasers), the
    Company will not amend or supplement the Offering Memorandum without your
    prior consent, which consent shall not be unreasonably withheld.

         (c)  If at any time prior to the completion of the distribution of the
    Securities by the Initial Purchasers (as determined and notified to the
    Company by the Representative), any event occurs as a result of which the
    Offering Memorandum as then amended or supplemented would include any 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 if it shall be necessary to amend or
    supplement the Offering Memorandum (including any document incorporated by
    reference therein which was filed under the Exchange Act) to comply with
    applicable law, the Company promptly will notify the Representative of the

    provide to the Representative pursuant to paragraph (a) of this Section 5 an

         (d)  The Company will arrange for the qualification of the Securities
    for sale under the laws of such jurisdictions as the Initial Purchasers may
    designate, will maintain such qualifications in effect so long as required
    for the sale of the Securities, provided that the Company by reason of any
    such qualification for sale shall not be required to (i) qualify as a
    foreign corporation or (ii) file a general consent to service of process in
    any such jurisdiction where it is not presently qualified or (iii) become
    subject to taxation as a foreign corporation. The Company will promptly
    advise the Representative of the receipt by the Company of any notification

    sale in any jurisdiction or the initiation or threatening of any proceeding
    for such purpose.

         (e)  Neither the Company nor any person acting on its behalf, nor to 
    the knowledge of the Company any of its Affiliates nor any person acting on
    their behalf, will directly or indirectly (i) make any offers or sales of
    any security, or solicit offers to buy any security, under circumstances
    that would require the registration of the Securities or the Common Stock
    issuable upon conversion thereof under the Act or (ii) engage in any form of
    general solicitation or general advertising (within the meaning of
    Regulation D) in connection with any offer or sale of the Securities in the
    United States.

         (f)  Neither the Company nor any person acting on its behalf, nor any 
    of its Affiliates nor any person acting on their behalf, will engage in any
    directed selling efforts with respect to the Securities within the meaning
    of Regulation S, and each of the Company, its Affiliates and each such
    person acting on its or their behalf will comply with the offering
    restrictions requirement of Regulation S.

         (g)  The Company shall, during any period prior to the Registration
    Termination Date in which the Company is not subject to Section 13 or 15(d)
    of the Exchange Act, make available, upon request, to any holder of
    Securities or Common Stock issuable upon conversion thereof in connection
    with any sale thereof and any prospective purchaser of Securities or Common
    Stock issuable upon conversion thereof from such holder the information
    specified in Rule 144A(d)(4) under the Act. The term "Registration
    Termination Date" means the earliest of (i) the second anniversary date of
    the Closing Date, (ii) the date on which the Securities and the Common Stock
    issuable upon conversion thereof may be sold by non-affiliates of the
    Company pursuant to paragraph (k) of Rule 144 (or any successor provision)
    promulgated by the Securities and Exchange Commission (the "Commission")
    under the Act and (iii) such earlier date on which all the Securities or the
    Common Stock issuable upon conversion thereof have




                                      8

    been sold pursuant to the Shelf Registration Statement (as defined in the
    Registration Agreement) to be filed pursuant to the Registration Agreement.

         (h)  The Company will not, and will use its best efforts to cause each
    of its Affiliates not to, resell any Securities or the Common Stock issuable
    upon conversion thereof which constitute "restricted securities" under Rule
    144 that have been reacquired by any of them, except pursuant to a
    registration statement.

         (i)  The Company shall include information substantially in the form 
    set forth in Exhibit B in the Offering Memorandum.

         (j)  The Company shall use its reasonable efforts in cooperation with
    the Initial Purchasers to permit the Securities to be eligible for clearance
    and settlement through The Depository Trust Company.

         (k)  The Company will not, for a period of 90 days following the date 
    of this Agreement, without the prior written consent of Smith Barney Inc.,
    which consent shall not be unreasonably withheld, offer, sell or contract to
    sell, or otherwise dispose of directly or indirectly, or announce the

    the Company may issue Common Stock, or grant options to purchase Common
    Stock, to employees and directors of the Company, (b) the Company may issue
    Common Stock or securities convertible into or exchangeable for Common Stock
    or issue or assume warrants or options to purchase Common Stock in
    connection with the acquisition of the assets, business, capital stock, or
    securities convertible into or exchangeable for the capital stock, of any
    person and (c) the Company may issue Common Stock, or issue options or
    warrants to purchase Common Stock, in connection with any investment or
    business arrangement entered into with any customer or vendor of the
    Company.

         (l)  The Company shall use its best efforts to obtain the waiver from
    LaSalle National Bank NI referred to in Section 1(l) of this Agreement.

         (m)  The Company will promptly advise the Representative when, prior to
    the completion of the distribution of the Securities by the Initial
    Purchasers, any document filed under the Exchange Act which is incorporated
    by reference in the Offering Memorandum shall have been filed with the
    Commission.

         6.   Conditions to the Obligations of the Initial Purchasers. The
obligations of the Initial Purchasers to purchase the Firm Securities and the
Option Securities, as the case may be, shall be subject to the accuracy of the

              Common Stock have been duly and validly authorized and issued and,

              preemptive rights;

                   (C) each of the Company's subsidiaries, has been duly
              incorporated and is validly existing as a corporation in good

              which it owns or leases material properties, in each case except
              for those jurisdictions where the failure to so qualify or to be

              the Company's subsidiaries have been duly and validly authorized
              and issued and, assuming receipt by such subsidiaries of the
              consideration therefor, are fully paid and nonassessable, and,

              Company's subsidiaries are owned by the Company free and clear of
              any perfected security interest and any other security interests,
              claims, liens or encumbrances;

              reorganization, insolvency, moratorium or other laws affecting
              creditors' rights generally from time to time in effect and
              assuming that the Indenture has been duly authorized, executed and

              the Indenture and delivered to and paid for by the Initial
              Purchasers pursuant to this Agreement, will constitute legal,
              valid and binding obligations of the Company entitled to the
              benefits of the Indenture; and the statements set forth under the
              heading "Description of Notes" in the Offering Memorandum, insofar
              as such statements purport to summarize certain provisions of the
              Securities and the Indenture, provide a fair summary of such
              provisions;

                   (F) the shares of Common Stock issuable upon conversion the
              Securities have been duly authorized for issuance, and when issued

                   (H) to the knowledge of such counsel, there is no pending or
              threatened action, suit or proceeding before any court or
              governmental agency, authority or body involving the Company or
              any of its subsidiaries of a character required to be disclosed in
              the Offering Memorandum which is not adequately disclosed in the
              Offering Memorandum, and, to the knowledge of such counsel, there
              is no contract or other document of a character required to be
              described in the Offering Memorandum which is not described as
              required, and the statements set forth in the Offering Memorandum
              under the headings "Risk Factors--No Assurance of Regulatory
              Clearance; Strict Governmental Regulation," "Business--Strategic
              Partnerships," "Business Intellectual Property,"
              "Business--Litigation" and "Business--Government Regulation",

              as such statements constitute a summary of legal matters,
              documents or proceedings referred to therein, provide a fair
              summary of such legal matters, documents and proceedings;

                   (I) to the knowledge of such counsel, no consent, approval,
              authorization or order of any court or governmental agency or body
              is required for the consummation by the Company of the
              transactions contemplated herein, except such as have been
              obtained under the Act and such as may be required under the blue
              sky laws (as to which such counsel need express no opinion) of any
              jurisdiction in connection with the purchase and distribution of
              the Securities by the Initial Purchasers and such other approvals
              (specified in such opinion) as have been obtained;

                   (J) neither the issue and sale of the Securities (assuming
              compliance by the Company and the Initial Purchasers with their
              covenants set forth in this Agreement), the execution and delivery
              of the Indenture and the Registration Agreement, the consummation
              of any other of the transactions contemplated in this Agreement or
              the Registration Agreement nor the fulfillment of the terms of
              this Agreement or the Registration Agreement will conflict with,
              result in a breach or violation of, or constitute a default under
              any law or the Certificate of Incorporation or by-laws of the
              Company or the terms of any indenture or other agreement or
              instrument known to such counsel and to which the Company or any
              of the Company's subsidiaries is a party or bound, or any
              judgment, order or decree known to such counsel to be applicable
              to the Company or to any of its subsidiaries of any court,
              regulatory body, administrative agency or governmental body having
              jurisdiction over the Company or any of the Company's
              subsidiaries, which breach, violation or default is reasonably
              likely to have a Material Adverse Effect;

                   (K) assuming the accuracy of the representations and
              warranties of the Initial Purchasers and compliance thereby with
              their agreements contained herein, it is not necessary in
              connection with the offer, sale and delivery of the Securities in
              the manner contemplated by this Agreement to register the
              Securities under the Act or to qualify the Indenture under the
              Trust Indenture Act; and

                   (L) the Company is not an "investment company" within the
              meaning of the Investment Company Act, without taking account of
              any exemption arising out of the number of holders of the
              Company's securities, and, if the Company conducts its business as
              set forth in the 

                                      12
<PAGE>   13



              Offering Memorandum and complies with the covenants binding upon
              it under the Indenture, will not become an "investment company"
              and will not be required to be registered under the Investment
              Company Act.

         In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws of any jurisdiction other than the State of
New York, the General Corporation Law of the State of Delaware or the United
States, to the extent they deem proper and specified in such opinion, upon the
opinion of other counsel whom they believe to be reliable and who are reasonably
satisfactory to counsel for the Initial Purchasers and (B) as to matters of
fact, to the extent they deem proper, on certificates of responsible officers of
the Company and public officials. References to the Offering Memorandum in this
paragraph (a)(i) include any supplements thereto at the Closing Date.

         In addition, such counsel shall state that in the course of the
preparation of the Offering Memorandum such counsel has participated in
discussions with Representative of the Company, the Company's accountants, the
Representative, and the Representative's counsel during which the contents of
drafts of the Offering Memorandum and portions of the documents incorporated by
reference therein were discussed and reviewed, and, although such counsel has
made no independent investigation or verification of the correctness or
completeness of the information included or incorporated by reference in the
Offering Memorandum and without assuming responsibility for the accuracy,
completeness or fairness of such information, nothing has come to such counsel's
attention that has caused such counsel to believe (except for financial
statements, schedules and other financial, market and statistical information
contained or incorporated by reference therein and information provided by the
Initial Purchasers for inclusion therein, as to all of which such counsel need
not express any belief) that the Offering Memorandum as of the date thereof or
the Closing Date contained or contains any untrue statement of a material fact
or omitted or omits to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading.

         (b)  The Representative shall have received from Counsel for the 
    Initial Purchasers such opinion or opinions, dated the Closing Date, with
    respect to the issuance and sale of the Securities, the Indenture, the
    Registration Agreement, the Offering Memorandum (together with any amendment
    or supplement thereof or thereto) and other related matters as the
    Representative may reasonably require, and the Company shall have furnished
    to such counsel such documents as they request for the purpose of enabling
    them to pass upon such matters.

         (c)  The Company shall have furnished to the Representative a
    certificate of the Company, signed by the Chairman of the Board or the
    President and the principal financial or accounting officer of the Company,
    dated the Closing Date, to the effect that


                                      13
<PAGE>   14




         the signers of such certificate have carefully examined the Offering
         Memorandum, any amendment or supplement to the Offering Memorandum and
         this Agreement and that:

                       (i) the representations and warranties of the Company in
                  this Agreement are true and correct on and as of the Closing
                  Date with the same effect as if made on the Closing Date and
                  the Company has complied with all the agreements and satisfied
                  all the conditions on its part to be performed or satisfied at
                  or prior to the Closing Date; and

                       (ii) since the date of the most recent financial
                  statements included in the Offering Memorandum (exclusive of
                  any amendment or supplement thereof or thereto), there has
                  been no change or development that would have a Material
                  Adverse Effect, whether or not arising from transactions in
                  the ordinary course of business, except as set forth in or
                  contemplated in the Offering Memorandum (exclusive of any
                  amendment or supplement thereof or thereto).

                  (d) At the Closing Date, KPMG Peat Marwick, LLP shall have
         furnished to the Representative a letter or letters, dated as of the
         Closing Date, in form and substance satisfactory to the Representative,
         confirming that they are independent certified public accountants with
         respect to the Company within the meaning of Rule 101 of the Code of
         Professional Conduct of the American Institute of Certified Public
         Accountants (the "AICPA") and stating in effect that:

                       (i) in their opinion the audited financial statements and
                  financial statement schedules included or incorporated by
                  reference in the Offering Memorandum and reported on by them
                  comply in form in all material respects with the applicable
                  accounting requirements of the Exchange Act and the related
                  published rules and regulations thereunder;

                       (ii) on the basis of a reading of the latest unaudited
                  financial statements made available by the Company and its
                  subsidiaries; their limited review in accordance with the
                  standards established by the AICPA of the unaudited interim
                  financial information as indicated in their report included or
                  incorporated by reference in the Offering Memorandum; carrying
                  out certain specified procedures (but not an examination in
                  accordance with generally accepted auditing standards) which
                  would not necessarily reveal matters of significance with
                  respect to the comments set forth in such letter; a reading of
                  the minutes of the meetings of the stockholders, directors and
                  executive, option, compensation and audit committees of the
                  Company and the Company's subsidiaries; and inquiries of
                  certain officials of the Company who have responsibility for
                  financial and accounting matters of the Company and its
                  subsidiaries as to transactions and events subsequent to

                  December 31, 1997, nothing came to their attention which
                  caused them to believe that:

                           (1) any unaudited financial statements included or
                           incorporated by reference in the Offering Memorandum
                           do not comply in form in all material respects with
                           applicable accounting requirements and with the
                           published rules and regulations of the Commission
                           with respect to financial statements included or
                           incorporated by reference in quarterly reports on
                           Form 10-Q under the Exchange Act; and said unaudited
                           financial statements are not, in all material
                           respects, in conformity with generally accepted
                           accounting principles applied on a basis
                           substantially consistent with that of the audited
                           financial statements included or incorporated by
                           reference in the Offering Memorandum; or

                           (2) with respect to the period subsequent to December
                           31, 1997, there were any changes, at a specified date
                           not more than three business days prior to the date
                           of the letter, in the long-term debt of the Company
                           and its subsidiaries or capital stock of the Company
                           or decreases in the stockholders' equity of the
                           Company or working capital of the Company and its
                           subsidiaries as compared with the amounts shown on
                           the December 31, 1997 consolidated balance sheet
                           included or incorporated by reference in the Offering
                           Memorandum, or for the period from January 1, 1998 to
                           such specified date there were any decreases, as
                           compared with the corresponding period in the
                           preceding year, in net income before income taxes or
                           in total or per share amounts of net income or
                           operating income of the Company and its subsidiaries,
                           except in all instances for changes or decreases set
                           forth in such letter, in which case the letter shall
                           be accompanied by an explanation by the Company as to
                           the significance thereof unless said explanation is
                           not deemed necessary by the Representative.

                       (iii) they have performed certain other specified
                  procedures as a result of which they determined that certain
                  information of an accounting, financial or statistical nature
                  (which is limited to accounting, financial or statistical
                  information derived from the general accounting records of the
                  Company and its subsidiaries) set forth in the Offering
                  Memorandum agrees with the accounting records of the Company
                  and its subsidiaries, excluding any questions of legal
                  interpretation.

                  References to the Offering Memorandum in this paragraph (d)
         include any amendment or supplement thereof or thereto at the date of
         the letter.

                  (e) Subsequent to the Execution Time or, if earlier, the dates
         as of which information is given in the Offering Memorandum (exclusive
         of any amendment or supplement thereof or thereto), there shall not
         have been (i) any change or decrease specified in the letter or letters
         referred to in paragraph (d) of this Section 6 or (ii) any change, or
         any development involving a prospective change, in or affecting the
         business or properties of the Company and its subsidiaries the effect
         of which, in any case referred to in clause (i) or (ii) above, is, in
         the judgment of the Representative, so material and adverse as to make
         it impractical or inadvisable to market the Securities as contemplated
         by the Offering Memorandum.

                  (f) Prior to the Closing Date, the Company shall have
         furnished to the Representative such further information, certificates
         and documents as the Representative may reasonably request.

                  (g) At the Closing Date, the Company shall execute and deliver
         to the Representative the Registration Agreement in the form of Exhibit
         C hereto.

                  (h) At the Closing Date, the Company shall have received from
         LaSalle National Bank NI, the waiver referred to in Section1(l) of this
         Agreement.

                  If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representative and Counsel for the
Initial Purchasers, this Agreement and all obligations of the Initial Purchasers
hereunder may be canceled at, or at any time prior to, the Closing Date by the
Representative. Notice of such cancellation shall be given to the Company in
writing or by telephone or telefax confirmed in writing and the Company shall
thereupon have no further obligation hereunder except as expressly provided in
Section 7 and Section 8 hereof.

                  The documents required to be delivered by this Section 6 shall
be delivered at the office of Counsel for the Company, 150 North Michigan
Avenue, Suite 2500, Chicago, Illinois 60601 on the Closing Date.

                  7. Reimbursement of Initial Purchasers' Expenses. If the sale
of the Securities provided for herein is not consummated because any condition
to the obligations of the Initial Purchasers set forth in Section 6 hereof is
not satisfied, because of any termination pursuant to Section 10 hereof or
because of any refusal, inability or failure on the part of the Company to
perform any agreement herein or comply with any provision hereof other than by
reason of a default by any of the Initial Purchasers in payment for the
Securities, the Company will reimburse the Initial Purchasers severally upon
demand for all out-of-pocket expenses 

                                      16
<PAGE>   17




(including reasonable fees and disbursements of counsel) that shall have been
reasonably incurred by them in connection with the proposed purchase and sale of
the Securities.

                  8. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless each Initial Purchaser, the directors, officers,
employees and agents of each Initial Purchaser and each person who controls any
Initial Purchaser within the meaning of either the Act or the Exchange Act
against any and all losses, claims, damages or liabilities, joint or several, to
which they or any of them may become subject under the Act, the Exchange Act or
other Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the Offering Memorandum or any
information provided by the Company to any holder or prospective purchaser of
Securities pursuant to Section 5(g), or in any amendment thereof or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances in which they were made,
not misleading, and agrees to reimburse each such indemnified party, as
incurred, for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any such untrue statement or alleged untrue
statement or omission or alleged omission made in the Offering Memorandum, or in
any amendment thereof or supplement thereto, in reliance upon and in conformity
with written information furnished to the Company by or on behalf of any Initial
Purchasers through the Representative specifically for inclusion therein and
provided further that the Company shall not be liable to any Initial Purchaser
under the indemnity agreement in this subsection (a) with respect to the
Offering Memorandum to the extent that any such loss, claim, damage or liability
of such Initial Purchaser results from the fact that such Initial Purchaser sold
Securities to a person as to whom it shall be established that there was not
sent or given, at or prior to the written confirmation of such sale, a copy of
the Offering Memorandum or the Offering Memorandum as then amended or
supplemented if the Company has previously furnished copies thereof to such
Initial Purchaser and the loss, claim, damage or liability of such Initial
Purchaser results from an untrue statement or omission of a material fact
contained in the Offering Memorandum that was corrected in the Offering
Memorandum as then amended or supplemented. This indemnity agreement will be in
addition to any liability which the Company may otherwise have.

                  (b) Each Initial Purchaser severally agrees to indemnify and
hold harmless the Company, its directors, its officers, and each person who
controls the Company within the meaning of either the Act or the Exchange Act,
to the same extent as the foregoing indemnity from the Company to each Initial
Purchaser, but only with reference to written information 

                                      17
<PAGE>   18




relating to such Initial Purchaser furnished to the Company by or on behalf of
such Initial Purchaser through the Representative specifically for inclusion in
the Offering Memorandum, or in any amendment thereof or supplement thereto. This
indemnity agreement will be in addition to any liability which any Initial
Purchaser may otherwise have. The Company acknowledges that the statements set
forth in the last paragraph of the cover page, the last paragraph on the inside
front cover page and under the heading "Plan of Distribution" in the Offering
Memorandum constitute the only information furnished in writing by or on behalf
of the Initial Purchasers for inclusion in the Offering Memorandum, and you, as
the Representative, confirm that such statements are correct.

                  (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure results
in the forfeiture by the indemnifying party of substantial rights and defenses
and (ii) will not, in any event, relieve the indemnifying party from any
obligations to any indemnified party other than the indemnification obligation
provided in paragraph (a) or (b) above. The indemnifying party shall be entitled
to appoint counsel of the indemnifying party's choice at the indemnifying
party's expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be satisfactory to the indemnified
party. Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying party to
represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party; provided, however, the indemnifying party shall not
be liable for the fees, costs or expenses of more than one separate counsel
(plus one local counsel in any jurisdiction), selected by Smith Barney Inc., in
any single action or proceeding for all of the indemnified parties unless the
indemnifying party consents or unless a

                                      18
<PAGE>   19




bona fide conflict of interest requires separate counsel for particular
indemnified parties. An indemnifying party will not, without the prior written
consent of the indemnified parties, settle or compromise or consent to the entry
of any judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.

                  (d) In the event that the indemnity provided in paragraph (a)
or (b) of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Initial Purchasers agree
to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending same) (collectively "Losses") to which the Company
and one or more of the Initial Purchasers may be subject in such proportion as
is appropriate to reflect the relative benefits received by the Company and by
the Initial Purchasers from the offering of the Securities; provided, however,
that in no case shall any Initial Purchaser be responsible for any amount in
excess of the purchase discount or commission applicable to the Securities
purchased by such Initial Purchaser hereunder. If the allocation provided by the
immediately preceding sentence is unavailable for any reason, the Company and
the Initial Purchasers shall contribute in such proportion as is appropriate to
reflect not only such relative benefits but also the relative fault of the
Company and of the Initial Purchasers in connection with the statements or
omissions that resulted in such Losses as well as any other relevant equitable
considerations. Benefits received by the Company shall be deemed to be equal to
the total net proceeds from the offering (before deducting expenses), and
benefits received by the Initial Purchasers shall be deemed to be equal to the
total purchase discounts and commissions, in each case as set forth on the cover
page of the Offering Memorandum. Relative fault shall be determined by reference
to whether any alleged untrue statement or omission relates to information
provided by the Company or the Initial Purchasers. The Company and the Initial
Purchasers agree that it would not be just and equitable if contribution were
determined by pro rata allocation or any other method of allocation that does
not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 8, each person who
controls an Initial Purchaser within the meaning of either the Act or the
Exchange Act and each director, officer, employee and agent of an Initial
Purchaser shall have the same rights to contribution as such Initial Purchaser,
and each person who controls the Company within the meaning of either the Act or
the Exchange Act and each officer and director of the Company shall have the
same rights to contribution as the Company, subject in each case to the
applicable terms and conditions of this paragraph (d).

                  9. Default by an Initial Purchaser. If any one or more Initial
Purchasers shall fail to purchase and pay for any of the Securities agreed to be
purchased by such Initial Purchaser hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Initial Purchasers shall be obligated severally to take
up and pay for (in the respective proportions which the principal amount of
Securities set forth opposite their names in Schedule I hereto bears to the
aggregate principal amount of Securities set forth opposite the names of all the
remaining Initial Purchasers) the Securities which the defaulting Initial
Purchaser or Initial Purchasers agreed but failed to purchase; provided,
however, that in the event that the aggregate principal amount of Securities
which the defaulting Initial Purchaser or Initial Purchasers agreed but failed
to purchase shall exceed 10% of the aggregate principal amount of Securities set
forth in Schedule I hereto, the remaining Initial Purchasers shall have the
right to purchase all, but shall not be under any obligation to purchase any, of
the Securities, and if such non-defaulting Initial Purchasers do not purchase
all the Securities, this Agreement will terminate without liability to any
non-defaulting Initial Purchaser or the Company. In the event of a default by
any Initial Purchaser as set forth in this Section 9, the Closing Date shall be
postponed for such period, not exceeding seven days, as the Representative shall
determine in order that the required changes in the Offering Memorandum or in
any other documents or arrangements may be effected. Nothing contained in this
Agreement shall relieve any defaulting Initial Purchaser of its liability, if
any, to the Company or any non-defaulting Initial Purchaser for damages
occasioned by its default hereunder.

                  10. Termination. This Agreement shall be subject to
termination in the absolute discretion of the Representative, by notice given to
the Company prior to delivery of and payment for the Securities, if prior to
such time (i) trading in or quotation of the Company's Common Stock shall have
been suspended by the Commission or the National Association of Securities
Dealers Automated Quotation National Market or trading in securities generally
on the New York Stock Exchange or the National Association of Securities Dealers
Automated Quotation National Market shall have been suspended or limited or
minimum prices shall have been established on either of such Exchange or Market
System, (ii) a banking moratorium shall have been declared either by Federal or
New York State authorities or (iii) there shall have occurred any outbreak or
escalation of hostilities, declaration by the United States of a national
emergency or war or other calamity or crisis the effect of which on financial
markets is such as to make it, in the judgment of the Representative,
impracticable or inadvisable to proceed with the offering or delivery of the
Securities as contemplated by the Offering Memorandum (exclusive of any
amendment or supplement thereof or thereto).

                  11. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Initial Purchasers set forth in or made
pursuant to this Agreement will remain in full force


                                      20
<PAGE>   21
and effect, regardless of any investigation made by or on behalf of the Initial
Purchasers or the Company or any of the officers, directors or controlling
persons referred to in Section 8 hereof, and will survive delivery of and
payment for the Securities. The provisions of Sections 7 and 8 hereof shall
survive the termination or cancellation of this Agreement.

                  12. Notices. All communications hereunder will be in writing 
and effective only on receipt, and, if sent to the Representative, will be 
mailed, delivered or telefaxed and confirmed to them in writing, care of Smith
Barney Inc. at 388 Greenwich Street, New York, New York, 10013; or, if sent to
the Company, will be mailed, delivered or telefaxed and confirmed to it in
writing at 5601 West Howard Street, Niles, Illinois 60714, attention: Stephen
L. Holden.

                  13. Successors. This Agreement will inure to the benefit of 
and be binding upon the parties hereto and their respective successors and the 
officers and directors and controlling persons referred to in Section 8 hereof,
and, except as expressly set forth in Section 5(g) hereof, no other person will 
have any right or obligation hereunder.

                  14. Applicable Law. This Agreement will be governed by and 
construed in accordance with the laws of the State of New York without regard 
to the conflicts of laws rules thereof.

                  15. Business Day. For purposes of this Agreement, "business 
day" means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a 
day on which banking institutions in the City of New York, New York are 
authorized or obligated by law, executive order or regulation to close.

                  16. Counterparts. This Agreement may be executed in one or 
more counterparts, each of which will be deemed to be an original, but all such
counterparts will together constitute one and the same instrument.

                       SELLING RESTRICTIONS FOR OFFERS AND
                         SALES OUTSIDE THE UNITED STATES


         (1)(a) The Securities have not been and will not be registered under
the Act and may not be offered or sold within the United States or to, or for
the account or benefit of, U.S. persons except in accordance with Regulation S
under the Act or pursuant to an exemption from the registration requirements of
the Act. Each Initial Purchaser represents and agrees that, except as otherwise
permitted by Section 4(a)(i) of the Agreement to which this is an exhibit, it
has offered and sold the Securities, and will offer and sell the Securities, (i)
as part of their distribution at any time and (ii) otherwise until 40 days after
the later of the commencement of the offering and the Closing Date, only in
accordance with Rule 903 of Regulation S under the Act. Accordingly, each
Initial Purchaser represents and agrees that neither it, nor any of its
affiliates nor any person acting on its or their behalf has engaged or will
engage in any directed selling efforts with respect to the Securities, and that
it and they have complied and will comply with the offering restrictions
requirements of Regulation S. Each Initial Purchaser agrees that, at or prior to
the confirmation of sale of Securities (other than a sale of Securities pursuant
to Section 4(a)(i) of the Agreement to which this is an exhibit), it shall have
sent to each distributor, dealer or person receiving a selling concession, fee
or other remuneration that purchases Securities from it during the restricted
period a confirmation or notice to substantially the following effect:

              "The Securities covered hereby have not been registered under the
         U.S. Securities Act of 1933 (the "Securities Act") and may not be
         offered or sold within the United States or to, or for the account or
         benefit of, U.S. persons (i) as part of their distribution at any time
         or (ii) otherwise until 40 days after the later of the commencement of
         the offering and December 10, 1997, except in either case in accordance
         with Regulation S or Rule 144A under the Securities Act. Terms used
         above have the meanings given to them by Regulation S."

         (b) Each Initial Purchaser also represents and agrees that it has not
entered and will not enter into any contractual arrangement with any distributor
with respect to the distribution of the Securities, except with its affiliates
or with the prior consent of the Company.

         (c) Terms used in this section have the meanings given to them by
Regulation S.

         (2) Each Initial Purchaser represents and agrees that (i) it has not
offered or sold, and, prior to the expiry of six months from the closing of the
offering of the Notes, will not offer 


                                      A-1

                  (a) The Company shall prepare and, not later than 60 days
         following the Closing Date, shall file with the Commission and
         thereafter, but no later than 120 days following the Closing Date,
         shall use its best efforts to cause to be declared effective under the

         the Securities and the Common Stock issuable upon conversion thereof by
         the Holders from time to time in accordance with the methods of
         distribution elected by such Holders and set forth in such Shelf
         Registration Statement.

                  (b) The Company shall use its best efforts to keep the Shelf
         Registration Statement continuously effective in order to permit the
         Prospectus forming part thereof to be usable by Holders until the
         earliest of (i) the second anniversary of the Closing Date, (ii) the

         used its best efforts to keep the Shelf Registration Statement

         action that would result in Holders of Securities covered thereby not
         being able to offer and sell such Securities during that period, unless

         counsel such action is required by or is advisable under applicable law
         or (y) such action is required pursuant to Section 2(c) hereof, and, in
         either case, so long as the Company promptly thereafter complies with
         the

                                      3
<PAGE>   4
         requirements of Section 3(i) hereof, if applicable. The Company shall
         not be deemed to have failed to use its best efforts to keep the Shelf
         Registration Statement effective during the requisite period if any
         such failure in the effectiveness of the Registration Statement is due
         solely to the actions of one or more Holders.

                  (c) The Company may suspend the use of the Prospectus for a
         period not to exceed 30 days in any three-month period or for three
         periods not to exceed an aggregate of 90 days in any twelve-month
         period for valid business reasons, to be determined by the Company in
         its sole reasonable judgment (not including avoidance of the Company's
         obligations hereunder), including, without limitation, the acquisition
         or divestiture of assets, public filings with the Commission, pending
         corporate developments and similar events; provided that the Company
         promptly thereafter complies with the requirements of Section 3(i)
         hereof, if applicable.

                  3. Registration Procedures. In connection with any Shelf
Registration Statement, the following provisions shall apply:

                  (a) The Company shall furnish to you, prior to the filing
         thereof with the Commission, a copy of any Shelf Registration
         Statement, and each amendment thereof and each amendment or supplement,
         if any, to the Prospectus included therein and shall use its best
         efforts to reflect in each such document, when so filed with the
         Commission, such comments as Smith Barney Inc. reasonably may propose.

                  (b) The Company shall ensure that (i) any Shelf Registration
         Statement and any amendment thereto and any Prospectus forming part
         thereof and any amendment or supplement thereto comply in all material
         respects with the Act and the rules and regulations thereunder, (ii)
         any Shelf Registration Statement and any amendment thereto does not,
         when it becomes effective, contain an untrue statement of a material
         fact or omit to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading and (iii) any
         Prospectus forming part of any Shelf Registration Statement, and any
         amendment or supplement to such Prospectus, does not include an untrue
         statement of a material fact or omit to state a material fact necessary
         in order to make the statements therein, in light of the circumstances
         under which they were made, not misleading; provided that no
         representation or agreement is made hereby with respect to information
         with respect to you, any Underwriter or any Holder required to be
         included in any Shelf Registration or Prospectus pursuant to the Act or
         the rules and regulations thereunder.

                                    (ii) of any request by the Commission for
                  amendments or supplements to the Shelf Registration Statement
                  or the Prospectus included therein or for additional
                  information.

                  initiation or threat of any proceeding for such purpose; and

                                    (iii) of the suspension of the use of the
                  Prospectus pursuant to Section 2(c) hereof or of the happening
                  of any event that requires the making of any changes in the
                  Shelf Registration Statement or the Prospectus so that, as of
                  such date, the statements therein are not misleading and do
                  not omit to state a material fact required to be stated
                  therein or necessary to make the statements therein (in the
                  case of the Prospectus, in light of the circumstances under

                  (d) The Company shall use its best efforts to obtain the

         offer and sale in such jurisdictions of the Securities and the Common
         Stock issued upon conversion thereof covered by such Shelf Registration
         Statement; provided, however, that the Company will not be required to
         qualify generally to do business in any jurisdiction where it is not
         then so qualified or to take any action which would subject it to
         general service of process or to taxation in any such jurisdiction
         where it is not then so subject.

                  (h) Subject to the terms of the Indenture (which terms shall
         control in the event of any conflict), The Company shall cooperate with
         the Holders to facilitate the timely preparation and delivery of
         certificates representing Securities or the Common Stock issued upon
         conversion thereof to be sold pursuant to any Shelf Registration
         Statement free of any restrictive legends and in such denominations and
         registered in such names as Holders may request prior to sales of
         Securities or the Common Stock issued upon conversion thereof pursuant
         to such Shelf Registration Statement.

                  (i) Upon the occurrence of any event contemplated by paragraph
         (c)(2)(iii) above, the Company shall promptly prepare a post-effective
         amendment to any Shelf Registration Statement or an amendment or
         supplement to the related Prospectus or file any other required
         document so that, as thereafter delivered to purchasers of the
         Securities or the Common Stock issued upon conversion thereof, the
         Prospectus will not include 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.

                  (j) The Company shall use its best efforts to cause The
         Depository Trust Company ("DTC") on the first Business Day following
         the effective date of any Shelf Registration Statement hereunder or as
         soon as possible thereafter to remove (i) from any existing CUSIP
         number assigned to the Securities any designation indicating that the



                                      6

<PAGE>   7
         Securities are "restricted securities", which efforts shall include
         delivery to DTC of a letter executed by the Company substantially in
         the form of Exhibit A hereto and (ii) any other stop or restriction on
         DTC's system with respect to the Securities. In the event the Company
         is unable to cause DTC to take actions described in the immediately
         preceding sentence, the Company shall take such actions as Smith Barney
         Inc. may reasonably request to provide, as soon as practicable, a CUSIP
         number for the Securities registered under such Shelf Registration
         Statement and to cause such CUSIP number to be assigned to the
         Securities (or to the maximum aggregate principal amount of the
         securities to which such number may be assigned). Upon compliance with
         the foregoing requirements of this Section 3(j), the Company shall
         provide the Trustee with global certificates for such Securities, in a
         form eligible for deposit with The Depository Trust Company.

                  (k) The Company shall use its best efforts to comply with all
         applicable rules and regulations of the Commission and shall make
         generally available to its security holders as soon as practicable
         after the effective date of the applicable Shelf Registration Statement
         an earnings statement satisfying the provisions of Section 11(a) of the
         Act and Rule 158 promulgated by the Commission thereunder.

                  (l) The Company shall use its best efforts to cause the
         Indenture to be qualified under the Trust Indenture Act in a timely
         manner.

                  (m) The Company may require each Holder of Securities or the
         Common Stock issued upon conversion thereof to be sold pursuant to any
         Shelf Registration Statement to furnish to the Company such information
         regarding the Holder and the distribution of such Securities or Common
         Stock as may, from time to time, be required by the Act and the rules
         and regulations promulgated thereunder, and the obligations of the
         Company to any Holder hereunder shall be expressly conditioned on the
         compliance of such Holder with such request.

                  (n) The Company shall, if requested, use its best efforts to
         promptly incorporate in a Prospectus supplement or post-effective
         amendment to a Shelf Registration Statement (i) such information as the
         Majority Holders provide or, if the Securities or Common Stock are
         being sold in an Underwritten Offering, as the Managing Underwriters
         and the Majority Holders reasonably agree should be included therein
         and provided to the Company in writing for inclusion in the Shelf
         Registration Statement or Prospectus, and (ii) such information as a
         Holder may provide from time to time to the Company in writing for
         inclusion in a Prospectus or any Shelf Registration Statement
         concerning such Holder and the distribution of such Holder's Securities
         and Common Stock and, in either case, shall make all required filings
         of such Prospectus supplement or post-effective amendment as soon as
         practicable after being notified in writing of the matters to be
         incorporated in such Prospectus supplement or post-effective amendment.

<PAGE>   8
                  (o) The Company shall enter into such agreements (including
         underwriting agreements) and take all other appropriate actions as may
         be reasonably requested in order to expedite or facilitate the
         registration or the disposition of the Securities or the Common Stock
         issuable upon conversion thereof, and in connection therewith, if an
         underwriting agreement is entered into, cause the same to contain
         indemnification provisions and procedures no less favorable than those
         set forth in Section 5 (or such other provisions and procedures
         acceptable to the Majority Holders and the Managing Underwriters, if
         any, with respect to all parties to be indemnified pursuant to Section
         5 from Holders of Securities or the Common Stock issuable upon
         conversion thereof to the Company).

                  (p) The Company shall (i) make reasonably available for
         inspection by the Holders of Securities or the Common Stock issued upon
         conversion thereof to be registered under a Shelf Registration
         Statement, any Underwriter participating in any disposition pursuant to
         such Shelf Registration Statement, and any attorney, accountant or
         other agent retained by the Holders or any such Underwriter all
         relevant financial and other records, pertinent corporate documents and
         properties of the Company and its subsidiaries; (ii) cause the
         Company's officers, directors and employees to supply all relevant
         information reasonably requested by the Holders or any such
         Underwriter, attorney, accountant or agent in connection with any such
         Shelf Registration Statement as is customary for similar due diligence
         examinations; provided, however, that any information that is
         designated in writing by the Company, in its sole discretion, as
         confidential at the time of delivery of such information shall be kept
         confidential by the Holders or any such Underwriter, attorney,
         accountant or agent, unless disclosure thereof is made in connection
         with a court proceeding or required by law, or such information has
         become available to the public generally through the Company or through
         a third party without an accompanying obligation of confidentiality;
         (iii) make such representations and warranties to the Holders of
         Securities or the Common Stock issued upon conversion thereof
         registered thereunder and the Underwriters, if any, in form, substance
         and scope as are customarily made by issuers to Underwriters and
         covering matters including, but not limited to, those set forth in the
         Purchase Agreement; (iv) obtain opinions of counsel to the Company and
         updates thereof (which counsel and opinions, in form, scope and
         substance, shall be reasonably satisfactory to the Managing
         Underwriters, if any) addressed to each selling Holder and the
         Underwriters, if any, covering such matters as are customarily covered
         in opinions requested in underwritten offerings and such other matters
         as may be reasonably requested by such Holders and Underwriters; (v)
         obtain "cold comfort" letters and updates thereof from the independent
         certified public accountants of the Company (and, if necessary, any
         other independent certified public accountants of any subsidiary of the
         Company or of any business acquired by the Company for which financial
         statements and financial data are, or are required to be, included in
         the Shelf Registration Statement), addressed to each selling Holder of
         Securities or the Common Stock issued upon conversion thereof
         registered




                                      8

<PAGE>   9
         thereunder (provided such Holder furnishes the accountants with such
         representations as the accountants customarily require in similar
         situations) and the Underwriters, if any, in customary form and
         covering matters of the type customarily covered in "cold comfort"
         letters in connection with primary underwritten offerings; and (vi)
         deliver such documents and certificates as may be reasonably requested
         by the Majority Holders and the Managing Underwriters, if any,
         including those to evidence compliance with Section 3(i) and with any
         customary conditions contained in the underwriting agreement or other
         agreement entered into by the Company. The foregoing actions set forth
         in clauses (iii), (iv), (v) and (vi) of this Section 3(p) shall be
         performed at (A) the effectiveness of such Shelf Registration Statement
         and each post-effective amendment thereto and (B) each closing under
         any underwriting or similar agreement as and to the extent required
         thereunder.

                  (q) From the date hereof until the end of the Shelf
         Registration Period, the Company shall be obligated to file with the
         Commission in a timely manner all reports required to be filed by it
         under the Exchange Act and all such reports shall comply with the rules
         and regulations of the Commission in all material respects and shall
         not contain an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading.

                  4. Registration Expenses. The Company shall bear all expenses
incurred in connection with the performance of its obligations under Sections 2
and 3 hereof and shall reimburse the Holders for the reasonable fees and
disbursements of one firm or counsel designated by the Majority Holders to act
as counsel for the Holders in connection therewith. Notwithstanding the
provisions of this Section 4, each Holder shall bear the expense of any broker's
commission, agency fee or Underwriter's discount or commission.

                  5.  Indemnification and Contribution.

                  (a) (i) In connection with any Shelf Registration Statement,
         the Company agrees to indemnify and hold harmless each Holder of
         Securities or Common Stock issued upon conversion thereof covered
         thereby (including the Initial Purchasers), the directors, officers,
         employees and agents of each such Holder and each person who controls
         any such Holder within the meaning of either the Act or the Exchange
         Act against any and all losses, claims, damages or liabilities, joint
         or several, to which they or any of them may become subject under the
         Act, the Exchange Act or other Federal or state statutory law or
         regulation, at common law or otherwise, insofar as such losses, claims,
         damages or liabilities (or actions in respect thereof) arise out of or
         are based upon any untrue statement or alleged untrue statement of a
         material fact contained in the Shelf Registration Statement as
         originally filed or in any amendment thereof, or in any preliminary
         Prospectus or Prospectus, or in any amendment thereof or supplement
         thereto, or arise out of or are based upon the omission or alleged
         omission to state therein a material fact required to be stated therein
         or necessary to make the statements therein



                  
                                      9

<PAGE>   10
         not misleading, and agrees to reimburse each such indemnified party, as
         incurred, for any legal or other expenses reasonably incurred by them
         in connection with investigating or defending any such loss, claim,
         damage, liability or action; provided, however, that the Company will
         not be liable in any case to the extent that any such loss, claim,
         damage or liability arises out of or is based upon (A) any such untrue
         statement or alleged untrue statement or omission or alleged omission
         made therein in reliance upon and in conformity with written
         information furnished to the Company by or on behalf of any such Holder
         or any Initial Purchaser specifically for inclusion therein, (B) use of
         a Shelf Registration Statement or the related Prospectus during a
         period when a stop order has been issued in respect of such Shelf
         Registration or any proceedings for that purpose have been initiated or
         use of a Prospectus when use of such Prospectus has been suspended
         pursuant to Section 2(c); provided, further, in each case, that Holders
         received prior notice of such stop order, initiation of proceedings or
         suspension or (C) if the Holder fails to deliver a Prospectus or the
         then current Prospectus. This indemnity agreement will be in addition
         to any liability which the Company may otherwise have.

                           (ii) The Company also agrees to indemnify or
         contribute to Losses, as provided in Section 5(d), of any Underwriters
         of Securities or the Common Stock issued upon conversion thereof
         registered under a Shelf Registration Statement, their officers and
         directors and each person who controls such Underwriters on
         substantially the same basis as that of the indemnification of the
         Initial Purchasers and the selling Holders provided in this Section
         5(a) and shall, if requested by any Holder, enter into an underwriting
         agreement reflecting such agreement, as provided in Section 3(o)
         hereof.

                  (b) Each Holder of Securities or Common Stock issued upon
         conversion thereof covered by a Shelf Registration Statement (including
         the Initial Purchasers) severally agrees to indemnify and hold harmless
         (i) the Company, (ii) each of its directors, (iii) each of its officers
         who signs such Shelf Registration Statement and (iv) each person who
         controls the Company within the meaning of either the Act or the
         Exchange Act to the same extent as the foregoing indemnity from the
         Company to each such Holder, but only with reference to written
         information relating to such Holder furnished to the Company by or on
         behalf of such Holder specifically for inclusion in the documents
         referred to in the foregoing indemnity. This indemnity agreement will
         be in addition to any liability which any such Holder may otherwise
         have.

                  (c) Promptly after receipt by an indemnified party under this
         Section 5 of notice of the commencement of any action, such indemnified
         party will, if a claim in respect thereof is to be made against the
         indemnifying party under this Section 5, notify the indemnifying party
         in writing of the commencement thereof; but the failure so to notify
         the indemnifying party (i) will not relieve it from liability under
         paragraph (a) or (b) above unless and to the extent it did not
         otherwise learn of such action and such failure results in the
         forfeiture by the indemnifying party of substantial rights and




                                      10






         
<PAGE>   11
         defenses and (ii) will not, in any event, relieve the indemnifying
         party from any obligations to any indemnified party other than the
         indemnification obligation provided in paragraph (a) or (b) above. The
         indemnifying party shall be entitled to appoint counsel of the
         indemnifying party's choice at the indemnifying party's expense to
         represent the indemnified party in any action for which indemnification
         is sought (in which case the indemnifying party shall not thereafter be
         responsible for the fees and expenses of any separate counsel retained
         by the indemnified party or parties except as set forth below);
         provided, however, that such counsel shall be reasonably satisfactory
         to the indemnified party. Notwithstanding the indemnifying party's
         election to appoint counsel to represent the indemnified party in an
         action, the indemnified party shall have the right to employ separate
         counsel (including local counsel), and the indemnifying party shall
         bear the reasonable fees, costs and expenses of such separate counsel
         (and local counsel) if (i) the use of counsel chosen by the
         indemnifying party to represent the indemnified party would present
         such counsel with a conflict of interest, (ii) the actual or potential
         defendants in, or targets of, any such action include both the
         indemnified party and the indemnifying party and the indemnified party
         shall have reasonably concluded that there may be legal defenses
         available to it and/or other indemnified parties which are different
         from or additional to those available to the indemnifying party, (iii)
         the indemnifying party shall not have employed counsel satisfactory to
         the indemnified party to represent the indemnified party within a
         reasonable time after notice of the institution of such action or (iv)
         the indemnifying party shall authorize the indemnified party to employ
         separate counsel at the expense of the indemnifying party; provided
         further, that the indemnifying party shall not be responsible for the
         fees and expenses of more than one separate counsel (together with
         appropriate local counsel) representing all the indemnified parties
         under paragraph (a)(i), paragraph (a)(ii) or paragraph (b) above. An
         indemnifying party will not, without the prior written consent of the
         indemnified parties, settle or compromise or consent to the entry of
         any judgment with respect to any pending or threatened claim, action,
         suit or proceeding in respect of which indemnification or contribution
         may be sought hereunder (whether or not the indemnified parties are
         actual or potential parties to such claim or action) unless such
         settlement, compromise or consent includes an unconditional release of 
         each indemnified party from all liability arising out of such claim, 
         action, suit or proceeding.
      
                  (d) In the event that the indemnity provided in paragraph (a)
         or (b) of this Section 5 is unavailable to or insufficient to hold
         harmless an indemnified party for any reason, then each applicable
         indemnifying party, in lieu of indemnifying such indemnified party,
         shall have a joint and several obligation to contribute to the
         aggregate losses, claims, damages and liabilities (including legal or
         other expenses reasonably incurred in connection with investigating or
         defending same) (collectively "Losses") to which such indemnified party
         may be subject in such proportion as is appropriate to reflect the
         relative benefits received by such indemnifying party, on the one hand,
         and such indemnified party, on the other hand, from the Initial
         Placement and the Shelf 

                                       11

<PAGE>   12

         Registration  Statement  which  resulted  in  such  Losses;   provided,
         however,  that in no case shall the Initial  Purchasers be responsible,
         in the aggregate,  for any amount in excess of the purchase discount or
         commission  applicable to such Security, as set forth on the cover page
         of the Offering  Memorandum,  nor shall any  Underwriter be responsible
         for any amount in excess of the  underwriting  discount  or  commission
         applicable to the  Securities  and Common Stock issued upon  conversion
         thereof  purchased  by such  Underwriter  under the Shelf  Registration
         Statement which resulted in such Losses. If the allocation  provided by
         the immediately  preceding  sentence is unavailable for any reason, the
         indemnifying  party and the indemnified  party shall contribute in such
         proportion as is appropriate to reflect not only such relative benefits
         but also the  relative  fault of such  indemnifying  party,  on the one
         hand, and such indemnified party, on the other hand, in connection with
         the  statements or omissions  which  resulted in such Losses as well as
         any other relevant equitable  considerations.  Benefits received by the
         Company  shall be  deemed  to be equal to the sum of (x) the  total net
         proceeds from the Initial Placement (before deducting  expenses) as set
         forth on the cover page of the  Offering  Memorandum  and (y) the total
         amount of additional interest which the Company was not required to pay
         as a result of registering  the Securities and Common Stock issued upon
         conversion  thereof covered by the Shelf  Registration  Statement which
         resulted in such Losses.  Benefits  received by the Initial  Purchasers
         shall be  deemed  to be  equal  to the  total  purchase  discounts  and
         commissions as set forth on the cover page of the Offering  Memorandum,
         and benefits  received by any other Holders shall be deemed to be equal
         to the value of receiving  Securities or the Common Stock issuable upon
         conversion  thereof  registered under the Act. Benefits received by any
         Underwriter  shall be  deemed  to be equal  to the  total  underwriting
         discounts  and  commissions,  as set  forth  on the  cover  page of the
         Prospectus  forming a part of the Shelf  Registration  Statement  which
         resulted  in  such  Losses.  Relative  fault  shall  be  determined  by
         reference to whether any alleged untrue  statement or omission  relates
         to information  provided by the indemnifying party, on the one hand, or
         by the indemnified  party, on the other hand. The parties agree that it
         would not be just and equitable if contribution  were determined by pro
         rata  allocation or any other method of allocation  which does not take
         account   of  the   equitable   considerations   referred   to   above.
         Notwithstanding  the provisions of this paragraph (d), no person guilty
         of fraudulent misrepresentation (within the meaning of Section 11(f) of
         the Act) shall be entitled to contribution  from any person who was not
         guilty  of such  fraudulent  misrepresentation.  For  purposes  of this
         Section 5, each  person who  controls  a Holder  within the  meaning of
         either the Act or the Exchange Act and each director, officer, employee
         and agent of such Holder shall have the same rights to  contribution as
         such  Holder,  and each  person who  controls  the  Company  within the
         meaning  of either the Act or the  Exchange  Act,  each  officer of the
         Company who shall have signed the Shelf Registration Statement and each
         director of the Company shall have the same rights to  contribution  as
         the  Company,  subject  in  each  case  to  the  applicable  terms  and
         conditions of this paragraph (d).

                                       12

<PAGE>   13
                  (e) The provisions of this Section 5 will remain in full force
         and effect, regardless of any investigation made by or on behalf of any
         Holder or the Company or any of the officers, directors or controlling
         persons referred to in Section 5 hereof, and will survive the sale by a
         Holder of Securities covered by a Shelf Registration Statement.

                  6.  Miscellaneous.

                  (a) No Inconsistent Agreements. The Company has not, as of the
         date hereof, entered into nor shall it, on or after the date hereof,
         enter into, any agreement with respect to its Securities that is
         inconsistent with the rights granted to the Holders herein or otherwise
         conflicts with the provisions hereof.

                  (b) Amendments and Waivers. The provisions of this Agreement,
         including the provisions of this sentence, may not be amended,
         qualified, modified or supplemented, and waivers or consents to
         departures from the provisions hereof may not be given, unless the
         Company has obtained the written consent of the Majority Holders;
         provided that with respect to any matter that directly or indirectly
         affects the rights of the Initial Purchasers hereunder, the Company
         shall obtain the written consent of the Initial Purchasers against
         which such amendment, qualification, supplement, waiver or consent is
         to be effective. Notwithstanding the foregoing (except the foregoing
         proviso), a waiver or consent to departure from the provisions hereof
         with respect to a matter that relates exclusively to the rights of
         Holders whose Securities are being sold pursuant to a Shelf
         Registration Statement and that does not directly or indirectly affect
         the rights of other Holders may be given by the Majority Holders,
         determined on the basis of Securities being sold rather than registered
         under such Shelf Registration Statement.

                  (c) Notices. All notices and other communications provided for
         or permitted hereunder shall be made in writing by hand-delivery,
         first-class mail, telex, telecopier, or air courier guaranteeing
         overnight delivery:

                      (1)  if to you, initially at the address set forth in the 
                  Purchase Agreement;

                      (2) if to any other Holder, at the most current address
                  given by such Holder to the Company in accordance with the
                  provisions of this Section 6(c), which address initially is,
                  with respect to each Holder, the address of such Holder
                  maintained by the Registrar under the Indenture, with a copy
                  in like manner to Smith Barney Inc.; and

                      (3) if to the Company, initially at its address set forth
                  in the Purchase Agreement.

                                       13

<PAGE>   14
                  All such notices and communications shall be deemed to have
been duly given when received, if delivered by hand or air courier, and when
sent, if sent by first-class mail, telex or telecopier.

                  The Initial Purchasers or the Company by notice to the other
may designate additional or different addresses for subsequent notices or
communications.

                  (d) Successors and Assigns. This Agreement shall inure to the
         benefit of and be binding upon the successors and assigns of each of
         the parties, including, without the need for an express assignment or
         any consent by the Company thereto, subsequent Holders. The Company
         hereby agrees to extend the benefits of this Agreement to any Holder
         and any such Holder may specifically enforce the provisions of this
         Agreement as if an original party hereto.

                  (e) Counterparts. This agreement may be executed in any number
         of counterparts and by the parties hereto in separate counterparts,
         each of which when so executed shall be deemed to be an original and
         all of which taken together shall constitute one and the same
         agreement.

                  (f) Headings. The headings in this agreement are for
         convenience of reference only and shall not limit or otherwise affect
         the meaning hereof.

                  (g) Governing Law. This agreement shall be governed by and
         construed in accordance with the laws of the State of New York
         applicable to agreements made and to be performed in said State,
         without regard to the conflicts of law rules thereof.

                  (h) Severability. In the event that any one of more of the
         provisions   contained  herein,  or  the  application  thereof  in  any
         circumstances, is held invalid, illegal or unenforceable in any respect
         for any reason,  the validity,  legality and enforceability of any such
         provision in every other respect and of the remaining provisions hereof
         shall not be in any way impaired or affected thereby, it being intended
         that  all  of  the  rights  and  privileges  of the  parties  shall  be
         enforceable to the fullest extent permitted by law.

                  (i) Securities Held by the Company, etc. Whenever the consent
         or approval of Holders of a specified percentage of principal amount of
         Securities or the Common Stock issuable upon conversion thereof is
         required hereunder, Securities or the Common Stock issued upon
         conversion thereof held by the Company or its Affiliates (other than
         subsequent Holders of Securities or the Common Stock issued upon
         conversion thereof if such subsequent Holders are deemed to be
         Affiliates solely by reason of their holdings of such Securities) shall
         not be counted in determining whether such consent or approval was
         given by the Holders of such required percentage.

                  As always, please do not hesitate to call if we can of further
assistance.

<PAGE>   14



         SECTION 2.01. Form and Dating. The Securities and the Trustee's
certificate of authentication shall be substantially in the form of Exhibit A
which is hereby incorporated in and expressly made a part of this Indenture.

         The Securities may have notations, legends or endorsements required by
law, stock exchange rule, agreements to which the Company is subject, if any, or
usage (provided that any such notation, legend or endorsement is in a form
acceptable to the Company). The Company shall furnish any such legend not
contained in Exhibit A to the Trustee in writing. Each Security shall be dated
the date of its authentication. The terms and provisions of the Securities set
forth in Exhibit A are part of the terms of this Indenture and to the extent
applicable, the Company and the Trustee, by their execution and delivery of this
Indenture, expressly agree to such terms and provisions and to be bound thereby.

         (a) Global Securities. The Securities are being offered and sold by the
Company pursuant to a Purchase Agreement relating to the Securities, dated April
8, 1998, among the Company and the Initial Purchaser (the "Purchase Agreement").

         Securities sold, whether in the United States to Qualified
Institutional Buyers ("QIBs") in reliance on Rule 144A under the Securities Act
("Rule 144A") or in offshore transactions in reliance on Regulation S under the
Securities Act ("Regulation S") shall be issued in the form of one or more
permanent global Securities (each, a "Global Security," and, collectively, the
"Global Securities") in definitive, fully registered form without interest
coupons with the Global Securities Legend and the Restricted Securities Legend
set forth in Exhibit A hereto. The Global Security shall be deposited on behalf
of the purchasers of the Securities represented thereby with the Trustee, at its
Chicago office, as custodian for the Depositary, and registered in the name of
the Depositary or a nominee of the Depositary (and, in the case of Regulation S,
for the accounts of designated agents holding on behalf of the Euroclear System
("Euroclear") or Cedel Bank, societe anonyme ("Cedel Bank")), duly executed by
the Company and authenticated by the Trustee as hereinafter provided. The
aggregate principal amount of the Global Security 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 hereinafter provided.

         (b) Book-Entry Provisions. This Section 2.01(b) shall apply only to a
Global Security deposited with or on behalf of the Depositary.

         The Company shall execute and the Trustee shall, in accordance with
this Section 2.01(b) and the written order of the Company, authenticate and
deliver initially one or more Global Securities that (i) shall be registered in
the name of Cede & Co. or other nominee of such Depositary and (ii) shall be
delivered by the Trustee to such Depositary or pursuant to such







                                      8
<PAGE>   15
Depositary's instructions or held by the Trustee as custodian for the Depositary
pursuant to a FAST Balance Certificate Agreement between the Depositary and the
Trustee.

         Members of, or participants in, the Depositary ("Agent Members") shall
have no rights under this Indenture with respect to any Global Security held on
their behalf by the Depositary or by the Trustee as the custodian of the
Depositary or under such Global Security, and the Depositary may be treated by
the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary
or impair, as between the Depositary and its Agent Members, the operation of
customary practices of such Depositary governing the exercise of the rights of a
holder of a beneficial interest in any Global Security.

         (c) Certificated Securities. Except as provided in Section 2.10, owners
of beneficial interests in Global Securities will not be entitled to receive
physical delivery of certificated Securities.

         SECTION 2.02. Execution, Authentication and Delivery. Two Officers
shall sign the Securities for the Company by manual or facsimile signature.

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

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

         Upon a written order of the Company signed by two Officers, the Trustee
shall authenticate the Securities for original issue up to an aggregate
principal amount of $97,750,000 and deliver such authenticated securities as
directed in such order. The aggregate principal amount of Securities outstanding
at any time shall not exceed such amount except as provided in Section 2.07.

         The Trustee may appoint one or more authenticating agents acceptable to
the Company to authenticate Securities. An authenticating agent may authenticate
Securities whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate.

         SECTION 2.03. Registrar, Paying Agent and Conversion Agent. The Company
shall maintain in Chicago, Illinois (i) an office or agency where Securities may
be presented for registration of transfer or for exchange (the "Registrar"),
(ii) an office or agency where Securities may be presented for payment (the
"Paying Agent") and (iii) an office or agency where Securities may be presented
for conversion (the "Conversion Agent"). The Registrar shall keep a register of
the Securities and of their transfer and exchange. The Company has initially
appointed the Trustee as its Registrar, Paying Agent and Conversion Agent in
Chicago. The Company may appoint one or more co-registrars, one or more
additional paying agents and one or more additional conversion agents in such
other locations as it shall determine. The term "Registrar" includes any
co-registrar, the term "Paying Agent" includes any additional paying agent and
the term "Conversion Agent" includes any additional conversion agent. The
Company may change any Paying Agent, Registrar or Conversion Agent without prior
notice to any Noteholder. The Company shall notify the Trustee of the name and
address of any newly-appointed Agent not a party to this Indenture. If the
Company fails to appoint or maintain another entity as Registrar, Paying Agent
or Conversion Agent, the Trustee shall act as such.

         SECTION 2.04. Paying Agent to Hold Money in Trust. The Company 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 Noteholders or the Trustee
all money held by the Paying Agent for the payment of principal or interest on
the Securities, and will notify the Trustee of any default by the Company 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 Company
at any time may require a Paying Agent to pay all money held by it to the
Trustee and to account for any money disbursed by it. Upon payment over to the
Trustee, the Paying Agent (if other than the Company or an Affiliate of the
Company) shall have no further liability for the money. If the Company or an
Affiliate of the Company acts as Paying Agent, it shall segregate and hold in a
separate trust fund for the benefit of the Noteholders all money held by it as
Paying Agent.

         SECTION 2.05. Noteholder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Noteholders. If the Trustee is not the Registrar,
the Company shall furnish to the Trustee on or 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 Noteholders.

         SECTION 2.06. Transfer and Exchange. Where Securities are presented to
the Registrar with a request to register a transfer or to exchange them for an
equal principal amount of Securities of other denominations, such Registrar
shall register the transfer or make the exchange if its requirements for such
transactions are met. To permit registrations of transfers


                                       10

<PAGE>   17

and exchanges, the Company shall issue and the Trustee shall authenticate
Securities at the Registrar's request. No service charge shall be made for any
registration of transfer or exchange (except as otherwise expressly permitted
herein), but the Company may require payment of a sum sufficient to cover any
transfer tax or similar governmental charge payable in connection therewith
(other than any such transfer tax or similar governmental charge payable upon
exchanges pursuant to Sections 2.10, 3.06, 3.08, 5.02 or 10.05 hereof).

         The Company shall not be required (i) to issue, register the transfer
of, or exchange Securities during a period beginning at the opening of business
15 days before the day of any selection of Securities for redemption under
Section 3.02 hereof and ending at the close of business on the day of selection,
or (ii) to exchange or register the transfer of any Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part.

         (a) Notwithstanding any provision to the contrary herein, so long as a
Global Security remains outstanding and is held by or on behalf of the
Depositary, transfers of a Global Security, in whole or in part, or of any
beneficial interest therein, shall only be made in accordance with Section
2.01(b) and this Section 2.06(a); provided, however, that beneficial interests
in a Global Security may be transferred to persons who take delivery thereof in
the form of a beneficial interest in the same Global Security in accordance with
the transfer restrictions set forth under the heading "Notice to Investors" in
the Offering Memorandum and the Restricted Securities Legend.

         (i) Transfer of Global Security. Transfers of a Global Security shall
     be limited to transfers of such Global Security in whole, but not in part,
     to nominees of the Depositary or to a successor of the Depositary or such
     successor's nominee.

         (ii) Other Exchanges. In the event that a Global Security is exchanged
     for Securities in definitive registered form pursuant to Section 2.10,
     prior to the effectiveness of a Shelf Registration Statement with respect
     to such Securities, such Securities may be exchanged only in accordance
     with such procedures as may from time to time be adopted by the Company are
     (including procedures intended to ensure that such transfers comply with
     Rule 144A or Regulation S under the Securities Act, as the case may be).

         (b) Except in connection with a Shelf Registration Statement
contemplated by and in accordance with the terms of the Registration Agreement,
if Securities are issued upon the registration of transfer, exchange or
replacement of Securities bearing the Restricted Securities Legend set forth in
Exhibit A hereto, or if a request is made to remove such Restricted Securities
Legend on Securities, the Securities so issued shall bear the Restricted
Securities Legend, or the Restricted Securities Legend shall not be removed, as
the case may be, unless there is delivered 



                                       11



 

<PAGE>   18



to the Company such satisfactory evidence, which may include an opinion of
counsel licensed to practice law in the State of New York, as may be reasonably
required by the Company, that neither the legend nor the restrictions on
transfer set forth therein are required to ensure that transfers thereof comply
with the provisions of Rule 144A, Rule 144 or Regulation S under the Securities
Act or that such Securities are not "restricted" within the meaning of Rule 144
under the Securities Act. Upon provision to the Company of such satisfactory
evidence, the Trustee, at the written direction of the Company, shall
authenticate and deliver Securities that do not bear the legend.

         (c) Neither the Trustee nor any Agent shall have any responsibility for
any actions taken or not taken by the Depositary.

         SECTION 2.07. Replacement Securities. If the holder of a Security
claims that the Security has been lost, destroyed or wrongfully taken or if such
Security is mutilated and is surrendered to the Registrar, the Company shall
issue and the Trustee shall authenticate a replacement Security if the Trustee's
and the Company's requirements (as shall have been previously communicated to
the Trustee in a written letter of standing instruction) are met. If required by
the Trustee, the Registrar or the Company, an indemnity bond must be sufficient
in the judgment of each of the foregoing to protect the Company, the Trustee,
any Agent or any authenticating agent from any loss which any of them may suffer
if a Security is replaced. The Company may charge for its expenses in replacing
a Security.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, or is about to be redeemed or
purchased by the Company pursuant to Article III hereof or converted into shares
of Common Stock pursuant to Article V hereof, the Company in its discretion may,
instead of issuing a new Security, pay, redeem or convert such Security, as the
case may be.

         Every replacement Security is an additional obligation of the Company.

         SECTION 2.08. Outstanding Securities. The Securities outstanding at any
time are all the Securities authenticated by the Trustee except for those
canceled by it, those delivered to it for cancellation, and those described in
this Section as not outstanding.

         If a Security is replaced, paid, redeemed or converted pursuant to
Section 2.07 hereof, it ceases to be outstanding unless, in the case of a
replaced Security, the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.


         If Securities are considered paid under Section 4.01 hereof, they cease
to be outstanding and interest on them ceases to accrue.



                                       12

  

<PAGE>   19




         A Security does not cease to be outstanding because the Company or an
Affiliate of the Company holds the Security.

         SECTION 2.09. Treasury Securities. In determining whether the
Noteholders of the required principal amount of Securities have concurred in any
direction, waiver or consent, Securities owned by the Company or an Affiliate of
the Company shall be considered as though they are not outstanding, except that
for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, waiver or consent, only Securities which a Trust
Officer knows are so owned shall be so disregarded.

         SECTION 2.10. Temporary Securities; Exchange of Global Security for
Certificated Securities. (a) Until definitive Securities are ready for delivery,
the Company may prepare and the Trustee shall authenticate temporary Securities.
Temporary Securities shall be substantially in the form of definitive Securities
but may have variations that the Company considers appropriate for temporary
Securities. Without unreasonable delay, the Company shall prepare and the
Trustee shall authenticate definitive Securities in exchange for temporary
Securities.

         (b) A Global Security deposited with the Depositary or with the Trustee
as custodian for the Depositary pursuant to Section 2.01 shall be transferred to
the beneficial owners thereof in the form of certificated securities only if (i)
the Depositary notifies the Company that it is unwilling or unable to continue
as Depositary for such Global Security or if at any time such Depositary ceases
to be a "clearing agency" registered under the Exchange Act and a successor
Depositary is not appointed by the Company within 90 days of such notice, or
(ii) an Event of Default has occurred and is continuing.

         (c) Any Global Security that is transferable to the beneficial owners
thereof in the form of certificated Securities pursuant to this Section 2.10
shall be surrendered by the Depositary to the Trustee located in Chicago,
Illinois to be so transferred, in whole or from time to time in part, without
charge, and the Trustee shall authenticate and deliver, upon such transfer of
each portion of such Global Security, an equal aggregate principal amount at
maturity of Securities of authorized denominations in the form of certificated
Securities. Any portion of a Global Security transferred pursuant to this
Section shall be executed, authenticated and delivered only in denominations of
$1,000 and any integral multiple thereof and registered in such names as the
Depositary shall direct. Any Securities in the form of certificated Securities
delivered in exchange for an interest in the Global Security shall, except as
otherwise provided by Section 2.06(b), bear the Restricted Securities Legend set
forth in Exhibit A hereto.

         (d) Prior to any transfer pursuant to Section 2.10(b), the registered
holder of a Global Security may grant proxies and otherwise authorize any
person, including Agent Members and persons that may hold interests through
Agent




                                       13

Members, to take any action which a holder is entitled to take under this
Indenture or the Securities.

         (e) In the event of the occurrence of either of the events specified in
Section 2.10(b), the Company will promptly make available to the Trustee a
reasonable supply of certificated Securities in definitive form without interest
coupons.

         SECTION 2.11. Cancellation. The Company at any time may deliver
Securities to the Registrar for cancellation. The Registrar, Paying Agent and
Conversion Agent shall forward to the Trustee any Securities surrendered to them
for registration of transfer, redemption, conversion, exchange or payment. The
Trustee shall promptly cancel all Securities surrendered for registration of
transfer, redemption, conversion, exchange, payment, replacement or cancellation
and shall destroy all canceled Securities unless the Company otherwise directs.
The Company may not issue new Securities to replace Securities that it has paid
or that have been delivered to the Registrar for cancellation or that any holder
has converted.

         SECTION 2.12. Defaulted Interest. If the Company fails to make a
payment of interest on the Securities, it shall pay such defaulted interest plus
any interest payable on the defaulted interest, in any lawful manner. It may pay
such defaulted interest, plus any such interest payable on it, to the persons
who are Noteholders on a subsequent special record date. The Company shall fix
any such record date and payment date. At least 15 days before any such record
date, the Company shall mail to Noteholders a notice that states the record
date, payment date, and amount of such interest to be paid.

                                   ARTICLE III

                                   Redemption

         SECTION 3.01. Notices to Trustee. If the Company elects to redeem
Securities pursuant to Section 3.07 hereof, it shall notify the Trustee of the
redemption date and the principal amount of Securities to be redeemed. The
Company shall give each notice provided for in this Section 3.01 at least 45
days before the redemption date (unless a shorter notice period shall be
satisfactory to the Trustee).

         SECTION 3.02. Selection of Securities to be Redeemed. If less than all
the Securities are to be redeemed, the Trustee shall select the Securities to be
redeemed by a method that complies with the requirements of the principal
national securities exchange, if any, on which the Securities are listed, or, if
the Securities are not so listed, on a pro rata basis, by lot or by such other
method as the Trustee considers fair and appropriate. The Trustee shall make the
selection not more than 60 days and not less than 30 days before the redemption
date from


                                       14



<PAGE>   21



Securities outstanding not previously called for redemption. The Trustee may
select for redemption portions of the principal of Securities that have
denominations larger than $1,000. Securities and portions of them it selects
shall be in amounts of $1,000 or integral multiples of $1,000. Provisions of
this Indenture that apply to Securities called for redemption also apply to
portions of Securities called for redemption. The Trustee shall notify the
Company promptly of the Securities or portions of Securities to be called for
redemption.

         If any Security selected for partial redemption is converted in part
after such selection, the converted portion of such Security shall be deemed (so
far as may be) to be the portion to be selected for redemption. The Securities
(or portions thereof) so selected shall be deemed duly selected for redemption
for all purposes hereof, notwithstanding that any such Security is converted in
whole or in part before the mailing of the notice of redemption. Upon any
redemption of less than all the Securities, the Company and the Trustee may
treat as outstanding any Securities surrendered for conversion during the period
15 days next preceding the mailing of a notice of redemption and need not treat
as outstanding any Security authenticated and delivered during such period in
exchange for the unconverted portion of any Security converted in part during
such period.

         SECTION 3.03. Notice of Redemption. At least 30 days but not more than
60 days before a redemption date, the Company shall mail a notice of redemption
to each holder whose Securities are to be redeemed at such holder's registered
address.

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

         (a) the redemption date;

         (b) the redemption price;

         (c) if any Security is being redeemed in part, the portion of the
     principal amount of such Security to be redeemed and that, after the
     redemption date, upon cancellation of such Security, a new Security or
     Securities in principal amount equal to the unredeemed portion will be
     issued in the name of the holder thereof;

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

         (e) that Securities called for redemption must be surrendered to the
     Paying Agent to collect the redemption price plus accrued interest;

         (f) that, unless the Company defaults in making such redemption
     payment or the Paying Agent is prohibited from making such payment pursuant
     to the terms of this


                                       15


  

<PAGE>   22


     Indenture, by law or otherwise, interest on Securities called for
     redemption ceases to accrue on and after the redemption date; and

         (g) the paragraph of the Securities pursuant to which the Securities
     called for redemption are being redeemed.

         Such notice shall also state the current Conversion Price and the date
on which the right to convert such Securities or portions thereof into Common
Stock of the Company will expire.

         At the Company's request, the Trustee shall give notice of redemption
in the Company's name and at its expense.

         SECTION 3.04. Effect of Notice of Redemption. Once notice of redemption
is mailed, Securities called for redemption become due and payable on the
redemption date at the price set forth in the Security.

         SECTION 3.05. Deposit of Redemption Price. On or before the redemption
date, the Company shall deposit with the Trustee or the Paying Agent money
sufficient to pay the redemption price of and accrued interest up to but not
including the redemption date on all Securities to be redeemed on that date
(subject to the right of holders of record on the relevant record date to
receive interest due on an interest payment date) unless theretofore converted
into Common Stock pursuant to the provisions hereof. The Trustee or such Paying
Agent shall return to the Company any money not required for that purpose.

         SECTION 3.06. Securities Redeemed in Part. Upon surrender of a Security
that is redeemed in part, the Company shall issue and the Trustee shall
authenticate for the holder at the expense of the Company a new Security equal
in principal amount to the unredeemed portion of the Security surrendered.

         SECTION 3.07. Optional Redemption. The Company may redeem all or any
portion of the Securities, upon the terms and at the redemption prices set forth
in each of the Securities. 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. Designated Event Offer. (a) In the event that, pursuant
to Section 4.07 hereof, the Company shall commence a Designated Event Offer, the
Company shall follow the procedures in this Section 3.08.




                                       16



  

<PAGE>   23




         (b) The Designated Event Offer shall remain open for a period specified
by the Company which shall be no less than 30 calendar days and no more than 60
calendar days following its commencement on the date of the mailing of notice in
accordance with Section 4.07(b) hereof (the "Commencement Date"), except to the
extent that a longer period is required by applicable law (the "Tender Period").
Upon the expiration of the Tender Period (the "Designated Event Payment Date"),
the Company shall purchase the principal amount of Securities required to be
purchased pursuant to Section 4.07 hereof (the "Offer Amount").

         (c) If the Designated Event Payment Date is on or after an interest
payment record date and on or before the related interest payment date, any
accrued interest to the related interest payment date will be paid to the person
in whose name a Security is registered at the close of business on such record
date, and no additional interest will be payable to Noteholders who tender
Securities pursuant to the Designated Event Offer.

         (d) The Company shall provide the Trustee with written notice of the
Designated Event Offer at least 10 Business Days before the Commencement Date.

         (e) Subject to Section 4.07(b), on or before the Commencement Date, the
Company or the Trustee (at the request and expense of the Company) shall send,
by first class mail, a notice to each of the Noteholders, which shall govern
the terms of the Designated Event Offer and shall state:

         (i) that the Designated Event Offer is being made pursuant to this
     Section 3.08 and Section 4.07 hereof and that all Securities tendered will
     be accepted for payment;

         (ii) the Offer Amount, the purchase price (as determined in accordance
     with Section 4.07 hereof), the length of time the Designated Event Offer
     will remain open and the Designated Event Payment Date;

         (iii) that any Security or portion thereof not tendered or accepted for
     payment will continue to accrue interest;

         (iv) that, unless the Company defaults in the payment of the Designated
     Event Payment, any Security or portion thereof accepted for payment
     pursuant to the Designated Event Offer shall cease to accrue interest after
     the Designated Event Payment Date;

         (v) that Noteholders electing to have a Security or portion thereof
     purchased pursuant to any Designated Event Offer will be required to
     surrender the Security, with the form entitled "Option of Noteholder To
     Elect Purchase" on the reverse of the Security



  
                                       17

     completed, to the Paying Agent at the address specified in the notice prior
     to the close of business on the third Business Day preceding the Designated
     Event Payment Date;

         (vi) that Noteholders will be entitled to withdraw their election if
     the Paying Agent receives, not later than the close of business on the
     second Business Day preceding the Designated Event Payment Date, or such
     longer period as may be required by law, a letter or a telegram, telex,
     facsimile transmission (receipt of which is confirmed and promptly followed
     by a letter) setting forth the name of the Noteholder, the principal amount
     of the Security or portion thereof the Noteholder delivered for purchase
     and a statement that such Noteholder is withdrawing his election to have
     the Security or portion thereof purchased and specifying the amount of such
     Notes (which must be equal to $1,000 in principal amount or an integral
     multiple thereof) with respect to which such withdrawal is effective; and

         (vii) that Noteholders whose Securities are being purchased only in
     part will be issued new Securities equal in principal amount to the
     unpurchased portion of the Securities surrendered, which unpurchased
     portion must be equal to $1,000 in principal amount or an integral multiple
     thereof.

         In addition, the notice shall contain all instructions and materials
that the Company shall reasonably deem necessary to enable such Noteholders to
tender Securities pursuant to the Designated Event Offer.

         (f) At least one Business Day prior to the Designated Event Payment
Date, the Company shall irrevocably deposit with the Trustee or the Paying Agent
in immediately available funds an amount equal to the Offer Amount to be held
for payment in accordance with the terms of this Section 3.08. On the Designated
Event Payment Date, the Company shall, to the extent lawful, (i) accept for
payment the Securities or portions thereof tendered pursuant to the Designated
Event Offer, (ii) deliver or cause to be delivered to the Trustee Securities so
accepted and (iii) deliver to the Trustee an Officers' Certificate stating such
Securities or portions thereof have been accepted for payment by the Company in
accordance with the terms of this Section 3.08. The Paying Agent shall promptly
(but in any case not later than five calendar days after the Designated Event
Payment Date) mail or deliver to each tendering Noteholder an amount equal to
the purchase price of the Securities tendered by such Noteholder, and the
Trustee shall promptly authenticate and mail or deliver to such Noteholders a
new Security equal in principal amount to any unpurchased portion of the
Security surrendered, if any; provided, that each new Security shall be in a
principal amount of $1,000 or an integral multiple thereof. Any Securities not
so accepted shall be promptly mailed or delivered by or on behalf of the Company
to the holder thereof. The Company will publicly announce the results of





                                       18

<PAGE>   25



the Designated Event Offer on, or as soon as practicable after, the Designated
Event Payment Date.

         (g) The Designated Event Offer shall be made by the Company in
compliance with all applicable provisions of the Exchange Act, and all
applicable tender offer rules promulgated thereunder, and shall include all
instructions and materials that the Company shall reasonably deem necessary to
enable such Noteholders to tender their Securities.

                                   ARTICLE IV

                                    Covenants

         SECTION 4.01. Payment of Securities. The Company shall pay the
principal of and interest on the Securities on the dates and in the manner
provided in the Securities. Principal and interest shall be considered paid on
the date due if the Paying Agent (other than the Company or an Affiliate of the
Company) holds on that date money designated for and sufficient to pay all
principal and interest then due and such Paying Agent is not prohibited from
paying such money to the Noteholders on that date pursuant to the terms of this
Indenture. To the extent lawful, the Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest (without regard to any applicable grace period) at the
rate borne by the Securities, compounded semiannually.

         SECTION 4.02. SEC Reports. Whether or not required by the rules and
regulations of the SEC, so long as any Securities are outstanding, the Company
will file with the SEC and furnish to the Trustee and to the holders of
Securities all quarterly and annual financial information required to be
contained in a filing with the SEC on Forms 10-Q and 10-K, including a
"Management's Discussion and Analysis of Financial Conditions and Results of
Operations" and, with respect to annual information only, a report thereon by
the Company's certified independent accountants.

         SECTION 4.03. Compliance Certificate. The Company shall deliver to the
Trustee, within 120 days after the end of each fiscal year of the Company, an
Officers' Certificate stating that a review of the activities of the Company and
its subsidiaries during the preceding fiscal year has been made under the
supervision of the signing Officers with a view to determining whether the
Company has kept, observed, performed and fulfilled its obligations under, and
complied with the covenants and conditions contained in, this Indenture, and
further stating, as to each such Officer signing such certificate, that to the
best of such Officer's knowledge the Company has kept, observed, performed and
fulfilled each and every covenant, and complied with the covenants and
conditions contained in this Indenture and is not in default in the performance
or observance of any of the terms, provisions and conditions hereof (or, if a





                                       19

  

<PAGE>   26



Default or Event of Default shall have occurred, describing all such Defaults or
Events of Default of which such Officer may have knowledge) and that to the best
of such Officer's knowledge no event has occurred and remains in existence by
reason of which payments on account of the principal or of interest, if any, on
the Securities are prohibited.

         One of the Officers signing such Officers' Certificate shall be either
the Company's principal executive officer, principal financial officer or
principal accounting officer.

         The Company will, so long as any of the Securities are outstanding,
deliver to the Trustee, forthwith upon becoming aware of any Default, Event of
Default or default in the performance of any covenant, agreement or condition
contained in this Indenture, an Officers' Certificate specifying such Default,
Event of Default or default.

         Immediately upon the occurrence of any event giving rise to an increase
in the interest rate on the Securities in accordance with paragraph 10 of the
form thereof or the termination of any such increase, the Company shall give the
Trustee notice of such increase or termination, of the interest rate borne by
the Securities after giving effect to such increase or termination and of the
event giving rise to such increase or termination (such notice to be contained
in an Officers' Certificate), and prior to receipt of such Officers' Certificate
the Trustee shall be entitled to assume that no such increase or termination has
occurred, as the case may be.

         SECTION 4.04. Stay, Extension and Usury Law. The Company covenants (to
the extent that it may lawfully do so) that it will not at any time insist upon,
plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay, extension or usury law wherever enacted, now or at any time hereafter
in force, which may affect the covenants or the performance of this Indenture;
and the Company (to the extent it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law, and covenants that it will not, by
resort to any such law, hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every
such power as though no such law has been enacted.

         SECTION 4.05. Corporate Existence. Except as provided in Article VII
hereof, the Company will do or cause to be done all things necessary to preserve
and keep in full force and effect its corporate existence and the corporate,
partnership or other existence of each Material Subsidiary of the Company in
accordance with the respective organizational documents of each Material
Subsidiary and the rights (charter and statutory), licenses and franchises of
the Company and its Material Subsidiaries; provided, however, that the Company
shall not be required to preserve any such right, license or franchise, or the
corporate, partnership or other existence of any Material Subsidiary, if the
Board of Directors shall determine that the




                                      20
<PAGE>   27



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 Noteholders.

         SECTION 4.06. Taxes. The Company shall, and shall cause each of its
Subsidiaries to, pay prior to delinquency all taxes, assessments and
governmental levies, except as contested in good faith and by appropriate
proceedings.

         SECTION 4.07. Designated Event. (a) Upon the occurrence of a Designated
Event, each holder of Securities shall have the right, in accordance with this
Section 4.07 and Section 3.08 hereof, to require the Company to repurchase all
or any part (equal to $1,000 or an integral multiple thereof) of such holder's
Securities pursuant to the terms of Section 3.08 (the "Designated Event Offer")
at a purchase price equal to 100% of the principal amount thereof, plus accrued
and unpaid interest thereon to the Designated Event Payment Date (the
"Designated Event Payment").

         (b) Within 30 days following any Designated Event, the Company shall
mail to each holder the notice provided by Section 3.08(e).

         SECTION 4.08. Investment Company Act. As long as any Notes are
outstanding, the Company will conduct its business and operations so as not to
become an "investment company" within the meaning of the Investment Company Act
of 1940, as amended (the "Investment Company Act"), and will take all steps
required in order for it to continue not to be an "investment company" and not
to be required to be registered under the Investment Company Act, including, if
necessary, redeployment of the assets of the Company.


                                    ARTICLE V

                                   Conversion

         SECTION 5.01. Conversion Privilege. A holder of a Security may convert
the principal amount thereof (or any portion thereof that is an integral
multiple of $1,000) into fully paid and nonassessable shares of Common Stock of
the Company at any time after 90 days following the Issuance Date and prior to
the close of business on the Business Day immediately preceding the maturity
date of the Security at the Conversion Price then in effect, except that, with
respect to any Security called for redemption, such conversion right shall
terminate at the close of business on the Business Day immediately preceding the
redemption date (unless the Company shall default in making the redemption
payment when it becomes due, in which case the conversion right shall terminate
on the date such default is cured). The number of shares of Common Stock
issuable upon conversion of a Security is determined by dividing the principal


                                       21


<PAGE>   28


amount of the Security converted by the conversion price in effect on the
Conversion Date (the "Conversion Price").

         The initial Conversion Price is stated in paragraph 9 of the Securities
and is subject to adjustment as provided in this Article V.

         Provisions of this Indenture that apply to conversion of all of a
Security also apply to conversion of a portion of it. A holder of Securities is
not entitled to any rights of a holder of Common Stock until such holder of
Securities has converted such Securities into Common Stock, and only to the
extent that such Securities are deemed to have been converted into Common Stock
under this Article V.

         SECTION 5.02. Conversion Procedure. To convert a Security, a holder
must satisfy the requirements in paragraph 9 of the Securities. The date on
which the holder satisfies all of those requirements is the conversion date (the
"Conversion Date"). As soon as practicable after the Conversion Date, the
Company shall deliver to the holder through the Conversion Agent a certificate
for the number of whole shares of Common Stock issuable upon the conversion and
a check for any fractional share determined pursuant to Section 5.03. The person
in whose name the certificate is registered shall become the stockholder of
record on the Conversion Date and, as of such date, such person's rights as a
Noteholder with respect to the converted Security shall cease; provided,
however, that no surrender of a Security on any date when the stock transfer
books of the Company shall be closed shall be effective to constitute the person
entitled to receive the shares of Common Stock upon such conversion as the
stockholder of record of such shares of Common Stock on such date, but such
surrender shall be effective to constitute the person entitled to receive such
shares of Common Stock as the stockholder of record thereof for all purposes at
the close of business on the next succeeding day on which such stock transfer
books are open; provided further, however, that such conversion shall be at the
Conversion Price in effect on the date that such Security shall have been
surrendered for conversion, as if the stock transfer books of the Company had
not been closed.

         No payment or adjustment will be made for accrued and unpaid interest
on a converted Security or for dividends or distributions on shares of Common
Stock issued upon conversion of a Security, but if any holder surrenders a
Security for conversion after the close of business on the record date for the
payment of an installment of interest and prior to the opening of business on
the next interest payment date, then, notwithstanding such conversion, the
interest payable on such interest payment date shall be paid to the holder of
such Security on such record date. In such event, unless such Security has been
called for redemption on or prior to such interest payment date, such Security,
when surrendered for conversion, must be accompanied by payment in funds
acceptable to the Company of an amount equal to the interest payable on such
interest payment date on the portion so converted.

<PAGE>   29




         If a holder converts more than one Security at the same time, the
number of whole shares of Common Stock issuable upon the conversion shall be
based on the total principal amount of Securities converted.

         Upon surrender of a Security that is converted in part, the Trustee
shall authenticate for the holder a new Security equal in principal amount to
the unconverted portion of the Security surrendered.

         SECTION 5.03. Fractional Shares. The Company will not issue fractional
shares of Common Stock upon conversion of a Security. In lieu thereof, the
Company will pay an amount in cash based upon the Daily Market Price of any such
fractional shares of Common Stock on the trading day prior to the date of
conversion.

         SECTION 5.04. Taxes on Conversion. The issuance of certificates for
shares of Common Stock upon the conversion of any Security shall be made without
charge to the converting Noteholder for such certificates or for any tax in
respect of the issuance of such certificates, and such certificates shall be
issued in the respective names of, or in such names as may be directed by, the
holder or holders of the converted Security; provided, however, that in the
event that certificates for shares of Common Stock are to be issued in a name
other than the name of the holder of the Security converted, such Security, when
surrendered for conversion, shall be accompanied by an instrument of assignment
or transfer, in form satisfactory to the Company, duly executed by the
registered holder thereof or his duly authorized attorney; and provided further,
however, that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
such certificates in a name other than that of the holder of the converted
Security, and the Company shall not be required to issue or deliver such
certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid or is
not applicable.

         SECTION 5.05. Company to Provide Stock. The Company shall at all times
reserve and keep available, free from preemptive rights, out of its authorized
but unissued Common Stock, solely for the purpose of issuance upon conversion of
Securities as herein provided, a sufficient number of shares of Common Stock to
permit the conversion of all outstanding Securities for shares of Common Stock.

         All shares of Common Stock which may be issued upon conversion of the
Securities shall be duly authorized, validly issued, fully paid and
nonassessable when so issued.

         SECTION 5.06. Adjustment of Conversion Price. The Conversion Price
shall be subject to adjustment from time to time as follows:



                                       23



<PAGE>   30




         (a) In case the Company shall (1) pay a dividend in shares of Common
Stock to holders of Common Stock, (2) make a distribution in shares of Common
Stock to holders of Common Stock, (3) subdivide its outstanding shares of Common
Stock into a greater number of shares of Common Stock or (4) combine its
outstanding shares of Common Stock into a smaller number of shares of Common
Stock, the Conversion Price in effect immediately prior to such action shall be
adjusted so that the holder of any Security thereafter surrendered for
conversion shall be entitled to receive the number of shares of Common Stock
which he would have owned immediately following such action had such Securities
been converted immediately prior thereto. Any adjustment made pursuant to this
subsection (a) shall become effective immediately after the record date in the
case of a dividend or distribution and shall become effective immediately after
the effective date in the case of a subdivision or combination.

         (b) In case the Company shall issue rights or warrants to substantially
all holders of Common Stock entitling them (for a period commencing no earlier
than the record date for the determination of holders of Common Stock entitled
to receive such rights or warrants and expiring not more than 45 days after such
record date) to subscribe for or purchase shares of Common Stock (or securities
convertible into Common Stock) at a price per share less than the Current Market
Price (as determined pursuant to subsection (f) below) of the Common Stock on
such record date, the Conversion Price shall be adjusted so that the same shall
equal the price determined by multiplying the Conversion Price in effect
immediately prior to such record date by a fraction of which the numerator shall
be the number of shares of Common Stock outstanding on such record date, plus
the number of shares of Common Stock which the aggregate offering price of the
offered shares of Common Stock (or the aggregate conversion price of the
convertible securities so offered) would purchase at such Current Market Price,
and of which the denominator shall be the number of shares of Common Stock
outstanding on such record date plus the number of additional shares of Common
Stock offered (or into which the convertible securities so offered are
convertible). Such adjustments shall become effective immediately after such
record date.

         (c) In case the Company shall distribute to all holders of Common Stock
shares of any class of Capital Stock of the Company other than Common Stock,
evidences of indebtedness or other assets (other than cash dividends out of
current or retained earnings), or shall distribute to substantially all holders
of Common Stock rights or warrants to subscribe for securities (other than those
Securities referred to in subsection (b) above), then in each such case the
Conversion Price shall be adjusted so that the same shall equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the date of such distribution by a fraction of which the numerator shall be the
Current Market Price (determined as provided in subsection (f) below) of the
Common Stock on the record date mentioned below less the then fair market value
(as determined by the Board of Directors, whose determination shall be


                                       24


  

<PAGE>   31



conclusive evidence of such fair market value and described in a Board
Resolution) of the portion of the assets so distributed or of such subscription
rights or warrants applicable to one share of Common Stock, and of which the
denominator shall be such Current Market Price of the Common Stock. Such
adjustment shall become effective immediately after the record date for the
determination of the holders of Common Stock entitled to receive such
distribution. Notwithstanding the foregoing, in case the Company shall issue
rights or warrants to subscribe for additional shares of the Company's capital
stock (other than those referred to in subsection (b) above) ("Rights") to
substantially all holders of Common Stock, the Company may, in lieu of making
any adjustment pursuant to this Section 5.06, make proper provision so that each
holder of a Security who converts such Security (or any portion thereof) after
the record date for such distribution and prior to the expiration or redemption
of the Rights shall be entitled to receive upon such conversion, in addition to
the shares of Common Stock issuable upon such conversion (the "Conversion
Shares"), a number of Rights to be determined as follows: (i) if such conversion
occurs on or prior to the date for the distribution to the holders of Rights of
separate certificates evidencing such Rights (the "Distribution Date"), the same
number of Rights to which a holder of a number of shares of Common Stock equal
to the number of Conversion Shares is entitled at the time of such conversion in
accordance with the terms and provisions of and applicable to the Rights; and
(ii) if such conversion occurs after the Distribution Date, the same number of
Rights to which a holder of the number of shares of Common Stock into which the
principal amount of the Security so converted was convertible immediately prior
to the Distribution Date would have been entitled on the Distribution Date in
accordance with the terms and provisions of and applicable to the Rights.

         (d) In case the Company shall, by dividend or otherwise, at any time
distribute to all holders of its Common Stock cash (including any distributions
of cash out of current or retained earnings of the Company but excluding any
cash that is distributed as part of a distribution requiring a Conversion Price
adjustment pursuant to paragraph (c) of this Section) in an aggregate amount
that, together with the sum of (x) the aggregate amount of any other
distributions to all holders of its Common Stock made in cash plus (y) all
Excess Payments, in each case made within the 12 months preceding the date fixed
for determining the stockholders entitled to such distribution (the
"Distribution Record Date") and in respect of which no Conversion Price
adjustment pursuant to paragraphs (c) or (e) of this Section or this paragraph
(d) has been made, exceeds 15% of the product of the Current Market Price per
share (determined as provided in paragraph (f) of this Section) of the Common
Stock on the Distribution Record Date multiplied by the number of shares of
Common Stock outstanding on the Distribution Record Date (excluding shares held
in the treasury of the Company), the Conversion Price shall be reduced so that
the same shall equal the price determined by multiplying such Conversion Price
in effect immediately prior to the effectiveness of the Conversion Price
reduction contemplated by this paragraph (d) by a fraction of which the


                                       25


<PAGE>   32



numerator shall be the Current Market Price per share (determined as provided in
paragraph (f) of this Section) of the Common Stock on the Distribution Record
Date less the amount of such cash and other consideration (including any Excess
Payments) so distributed applicable to one share of Common Stock (equal to the
aggregate amount of such cash and other consideration (including any Excess
Payments) divided by the number of shares of Common Stock outstanding on the
Distribution Record Date) and the denominator shall be such Current Market Price
per share (determined as provided in paragraph (f) of this Section) of the
Common Stock on the Distribution Record Date, such reduction to become effective
immediately prior to the opening of business on the day following the
Distribution Record Date.

         (e) In case a tender offer or other negotiated transaction made by the
Company or any Subsidiary of the Company for all or any portion of the Common
Stock shall be consummated, if an Excess Payment is made in respect of such
tender offer or other negotiated transaction and the amount of such Excess
Payment, together with the sum of (x) the aggregate amount of all Excess
Payments plus (y) the aggregate amount of all distributions to all holders of
the Common Stock made in cash (including any distributions of cash out of
current or retained earnings of the Company), in each case made within the 12
months preceding the date of payment of such current negotiated transaction
consideration or expiration of such current tender offer, as the case may be
(the "Purchase Date"), and as to which no adjustment pursuant to paragraph (c)
or paragraph (d) of this Section or this paragraph (e) has been made, exceeds
15% of the product of the Current Market Price per share (determined as provided
in paragraph (f) of this Section) of the Common Stock on the Purchase Date
multiplied by the number of shares of Common Stock outstanding (including any
tendered shares but excluding any shares held in the treasury of the Company or
any Subsidiary of the Company) on the Purchase Date, the Conversion Price shall
be reduced so that the same shall equal the price determined by multiplying such
Conversion Price in effect immediately prior to the effectiveness of the
Conversion Price reduction contemplated by this paragraph (e) by a fraction of
which the numerator shall be the Current Market Price per share (determined as
provided in paragraph (f) of this Section) of the Common Stock on the Purchase
Date less the amount of such Excess Payments and such cash distributions, if
any, applicable to one share of Common Stock (equal to the aggregate amount of
such Excess Payments and such cash distributions divided by the number of shares
of Common Stock outstanding on the Purchase Date) and the denominator shall be
such Current Market Price per share (determined as provided in paragraph (f) of
this Section) of the Common Stock on the Purchase Date, such reduction to become
effective immediately prior to the opening of business on the day following the
Purchase Date.

         (f) The "Current Market Price" per share of Common Stock on any date
shall be deemed to be the average of the Daily Market Prices for the shorter of
(i) 30 consecutive Business Days ending on the last full Trading Day on the
exchange or market referred to in



                                       26



<PAGE>   33



determining such Daily Market Prices prior to the time of determination or (ii)
the period commencing on the date next succeeding the first public announcement
of the issuance of such rights or such warrants or such other distribution or
such negotiated transaction through such last full trading day on the exchange
or market referred to in determining such Daily Market Prices prior to the time
of determination.

         (g) "Excess Payment" means the excess of (A) the aggregate of the cash
and fair market value of other consideration paid by the Company or any of its
Subsidiaries with respect to the shares acquired in a tender offer or other
negotiated transaction over (B) the Daily Market Price on the Trading Day
immediately following the completion of such tender offer or other negotiated
transaction multiplied by the number of acquired shares.

         (h) In any case in which this Section 5.06 shall require that an
adjustment be made immediately following a record date for an event, the Company
may elect to defer, until such event, issuing to the holder of any Security
converted after such record date the shares of Common Stock and other Capital
Stock of the Company issuable upon such conversion over and above the shares of
Common Stock and other Capital Stock of the Company issuable upon such
conversion only on the basis of the Conversion Price prior to adjustment; and,
in lieu of the shares the issuance of which is so deferred, the Company shall
issue or cause its transfer agents to issue due bills or other appropriate
evidence of the right to receive such shares.

         SECTION 5.07. No Adjustment. No adjustment in the Conversion Price
shall be required until cumulative adjustments amount to 1% or more of the
Conversion Price as last adjusted; provided, however, that any adjustments which
by reason of this Section 5.07 are not required to be made shall be carried
forward and taken into account in any subsequent adjustment. All calculations
under this Article V shall be made to the nearest cent or to the nearest
one-hundredth of a share, as the case may be. No adjustment need be made for
rights to purchase Common Stock pursuant to a Company plan for reinvestment of
dividends or interest. No adjustment need be made for a change in the par value
or no par value of the Common Stock.

         SECTION 5.08. Other Adjustments. (a) In the event that, as a result of
an adjustment made pursuant to Section 5.06 above, the holder of any Security
thereafter surrendered for conversion shall become entitled to receive any
shares of Capital Stock of the Company other than shares of its Common Stock,
thereafter the Conversion Price of such other shares so receivable upon
conversion of any Securities shall be subject to adjustment from time to time in
a manner and on terms as nearly equivalent as practicable to the provisions with
respect to Common Stock contained in this Article V.

         (b) In the event that shares of Common Stock are not delivered after
the expiration of any of the rights or warrants referred to in Section 5.06(b)
and Section 5.06(c) 

                                       27

<PAGE>   34


hereof, the Conversion Price shall be readjusted to the Conversion Price which
would otherwise be in effect had the adjustment made upon the issuance of such
rights or warrants been made on the basis of delivery of only the number of
shares of Common Stock actually delivered.

         SECTION 5.09. Adjustments for Tax Purposes. The Company may, at its
option, make such reductions in the Conversion Price, in addition to those
required by Section 5.06 above, as it determines to be advisable in order that
any stock dividend, subdivision of shares, distribution of rights to purchase
stock or securities or distribution of securities convertible into or
exchangeable for stock made by the Company to its stockholders will not be
taxable to the recipients thereof.

         SECTION 5.10. Adjustments by the Company. The Company from time to time
may, to the extent permitted by law, reduce the Conversion Price by any amount
for any period of at least 20 days, in which case the Company shall give at
least 15 days' notice of such reduction in accordance with Section 5.11, if the
Board of Directors has made a determination that such reduction would be in the
best interests of the Company, which determination shall be conclusive.

         SECTION 5.11. Notice of Adjustment. Whenever the Conversion Price is
adjusted, the Company shall promptly mail to Noteholders at the addresses
appearing on the Registrar's books a notice of the adjustment and file with the
Trustee an Officers' Certificate briefly stating the facts requiring the
adjustment and the manner of computing it. The certificate shall be conclusive
evidence of the correctness of such adjustment.

         SECTION 5.12. Notice of Certain Transactions. In the event that:

         (1) the Company takes any action which would require an adjustment in
the Conversion Price;

         (2) the Company takes any action that would require a supplemental
indenture pursuant to Section 5.13; or

         (3) there is a dissolution or liquidation of the Company;

a holder of a Security may wish to convert such Security into shares of Common
Stock prior to the record date for or the effective date of the transaction so
that he may receive the rights, warrants, securities or assets which a holder of
shares of Common Stock on that date may receive. Therefore, the Company shall
mail to Noteholders at the addresses appearing on the Registrar's books and the
Trustee a notice stating the proposed record or effective date, as the case may
be. The Company shall mail the notice at least 15 days before such date;
however,


                                       28
<PAGE>   35
failure to mail such notice or any defect therein shall not affect the validity
of any transaction referred to in clause (1), (2) or (3) of this Section 5.12.

         SECTION 5.13. Effect of Reclassifications, Consolidations, Mergers or
Sales on Conversion Privilege. If any of the following shall occur, namely: (i)
any reclassification or change of outstanding shares of Common Stock issuable
upon conversion of Securities (other than a change in par value, or from par
value to no par value, or from no par value to par value, or as a result of a
subdivision or combination), (ii) any consolidation or merger to which the
Company is a party other than a merger in which the Company is the continuing
corporation and which does not result in any reclassification of, or change
(other than a change in name, or par value, or from par value to no par value,
or from no par value to par value or as a result of a subdivision or
combination) in, outstanding shares of Common Stock or (iii) any sale or
conveyance of all or substantially all of the property or business of the
Company as an entirety, then the Company, or such successor or purchasing
corporation, as the case may be, shall, as a condition precedent to such
reclassification, change, consolidation, merger, sale or conveyance, execute and
deliver to the Trustee a supplemental indenture in form satisfactory to the
Trustee providing that the holder of each Security then outstanding shall have
the right to convert such Security into the kind and amount of shares of stock
and other securities and property (including cash) receivable upon such
reclassification, change, consolidation, merger, sale or conveyance by a holder
of the number of shares of Common Stock deliverable upon conversion of such
Security immediately prior to such reclassification, change, consolidation,
merger, sale or conveyance. Such supplemental indenture shall provide for
adjustments of the Conversion Price which shall be as nearly equivalent as may
be practicable to the adjustments of the Conversion Price provided for in this
Article V. The foregoing, however, shall not in any way affect the right a
holder of a Security may otherwise have, pursuant to clause (ii) of the last
sentence of subsection (c) of Section 5.06, to receive Rights upon conversion of
a Security. If, in the case of any such consolidation, merger, sale or
conveyance, the stock or other securities and property (including cash)
receivable thereupon by a holder of Common Stock includes shares of stock or
other securities and property of a corporation other than the successor or
purchasing corporation, as the case may be, in such consolidation, merger, sale
or conveyance, then such supplemental indenture shall also be executed by such
other corporation and shall contain such additional provisions to protect the
interests of the holders of the Securities as the Board of Directors of the
Company shall reasonably consider necessary by reason of the foregoing. The
provision of this Section 5.13 shall similarly apply to successive
consolidations, mergers, sales or conveyances.

         In the event the Company shall execute a supplemental indenture
pursuant to this Section 5.13, the Company shall promptly file with the Trustee
an Officers' Certificate briefly stating the reasons therefor, the kind or
amount of shares of stock or securities or property (including cash) receivable
by holders of the Securities upon the conversion of their Securities





                                       29
<PAGE>   36



after any such reclassification, change, consolidation, merger, sale or
conveyance and any adjustment to be made with respect thereto.

         SECTION 5.14. Trustee's Disclaimer. The Trustee has no duty to
determine when an adjustment under this Article V should be made, how it should
be made or what such adjustment should be, but may accept as conclusive evidence
of the correctness of any such adjustment, and shall be protected in relying
upon the Officers' Certificate with respect thereto which the Company is
obligated to file with the Trustee pursuant to Section 5.11. The Trustee makes
no representation as to the validity or value of any securities or assets issued
upon conversion of Securities, and the Trustee shall not be responsible for the
Company's failure to comply with any provisions of this Article V.

         The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed
pursuant to Section 5.13, but may accept as conclusive evidence of the
correctness thereof, and shall be protected in relying upon, the Officers'
Certificate with respect thereto which the Company is obligated to file with the
Trustee pursuant to Section 5.13.

                                   ARTICLE VI

                                   Successors

         SECTION 6.01. Merger, Consolidation or Sale of Assets. The Company may
not consolidate or merge with or into any person (whether or not the Company is
the surviving corporation), or sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its properties or assets
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, lease, 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 corporation formed by or surviving any such consolidation or
    merger (if other than the Company) or the corporation to which such sale,
    assignment, transfer, lease, conveyance or other disposition will have been
    made assumes all the Obligations of the Company, pursuant to a supplemental
    indenture in a form reasonably satisfactory to the Trustee, under the
    Securities and the Indenture;

                                       30

<PAGE>   37

         (c) any such sale, assignment, transfer, lease, conveyance or other
    disposition of all or substantially all of the Company's properties or
    assets shall be as an entirety or virtually as an entirety to one
    corporation;

         (d) immediately after such transaction no Default or Event of Default
    exists; and

         (e) the Company or such corporation shall have delivered to the Trustee
    an Officers' Certificate and an Opinion of Counsel, each stating that such
    transaction and the supplemental indenture comply with the Indenture and
    that all conditions precedent in the Indenture relating to such transaction
    have been satisfied.

         SECTION 6.02. 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 Company in
accordance with Section 6.01 hereof, the successor corporation formed by such
consolidation or into or with which the Company is merged or the corporation to
which such sale, assignment, transfer, lease, conveyance or other disposition is
made shall succeed to, and be substituted for and may exercise every right and
power of, the Company under this Indenture with the same effect as if such
successor person has been named as the Company herein; provided, however, that
the predecessor Company in the case of a sale, assignment, transfer, lease,
conveyance or other disposition shall not be released from the obligation to pay
the principal of and interest on the Securities.

                                   ARTICLE VII

                              Defaults and Remedies

         SECTION 7.01. Events of Default. An "Event of Default" occurs if:

         (a) the Company defaults in the payment of interest on any Security
    when the same becomes due and payable, and the Default continues for a
    period of 30 days after the date due and payable;

         (b) the Company defaults in the payment of the principal of any
    Security when the same becomes due and payable at maturity, upon redemption
    or otherwise;

         (c) the Company fails to observe or perform any covenant or agreement
    contained in Section 4.07 hereof;

         (d) the Company fails to observe or perform any other covenant or
    agreement contained in this Indenture or the Securities required by it to be
    performed and the 




                                       31
<PAGE>   38


    Default continues for a period of 60 days after the receipt of written
    notice from the Trustee to the Company or from the holders of 25% in
    aggregate principal amount of the then outstanding Securities to the Company
    and the Trustee stating that such notice is a "Notice of Default";

         (e) there is a 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 Material
    Subsidiary of the Company (or the payment of which is guaranteed by the
    Company or any Material Subsidiary of the Company), whether such
    Indebtedness or guarantee now exists or is created after the Issuance Date,
    which default (i) is caused by a failure to pay when due principal of or
    interest on such Indebtedness within the grace period provided for in such
    Indebtedness (which failure continues beyond any applicable grace period) (a
    "Payment Default") or (ii) results in the acceleration of such Indebtedness
    prior to its express maturity (without such acceleration being rescinded or
    annulled) and, in each case, the principal amount of any such Indebtedness,
    together with the principal amount of any other such Indebtedness under
    which there is a Payment Default or the maturity of which has been so
    accelerated, aggregates $10 million or more;

         (f) a final, non-appealable judgment or final non-appealable judgments
    (other than any judgment as to which a reputable insurance company has
    accepted full liability) for the payment of money are entered by a court or
    courts of competent jurisdiction against the Company or any Material
    Subsidiary of the Company and remain undischarged for a period (during which
    execution shall not be effectively stayed) of 60 days, provided that the
    aggregate of all such judgments exceeds $5 million;

         (g) the Company or any Material Subsidiary pursuant to or within the
    meaning of any Bankruptcy Law: (i) commences a voluntary case, (ii) consents
    to the entry of an order for relief against it in an involuntary case in
    which it is the debtor, (iii) consents to the appointment of a Custodian of

    assignment for the benefit of its creditors, or (v) makes the admission in
    writing that it generally is unable to pay its debts as the same become due;
    or

         (h) a court of competent jurisdiction enters an order or decree under
    any Bankruptcy Law that: (i) is for relief against the Company or any
    Material Subsidiary of the Company in an involuntary case, (ii) appoints a
    Custodian of the Company or any Material Subsidiary of the Company or for
    all or substantially all of its property, and the order or decree remains
    unstayed and in effect for 60 days or (iii) orders the liquidation of the
    Company or any Material Subsidiary of the Company, and the order or decree
    remains unstayed and in effect for 60 days.

Law.

         SECTION 7.02. Acceleration. If an Event of Default (other than an Event
of Default specified in clauses (g) and (h) of Section 7.01 hereof) occurs and
is continuing, the Trustee by notice to the Company, or the Noteholders of at
least 25% in principal amount of the then-outstanding Securities by notice to
the Company and the Trustee, may declare all the Securities to be due and
payable. Upon such declaration, the principal of, premium, if any, and accrued
and unpaid interest on the Securities shall be due and payable immediately. If
an Event of Default specified in clause (g) or (h) of Section 7.01 hereof
occurs, the principal of, premium, if any, and accrued and unpaid interest on
the Securities shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any
Noteholder. The Noteholders of a majority in aggregate principal amount of the
then-outstanding Securities by notice to the Trustee may rescind an acceleration
and its consequences if the rescission would not conflict with any judgment or
decree, if all amounts payable to the Trustee pursuant to Section 8.07 hereof
have been paid and if all existing Events of Default have been cured or waived
except nonpayment of principal or interest that has become due solely because of
the acceleration.

         SECTION 7.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal or interest on the Securities or to enforce the performance of any
provision of the Securities or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Noteholder 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 7.04. Waiver of Past Defaults. The Noteholders of a majority in
aggregate principal amount of the then-outstanding Securities by notice to the
Trustee may waive an existing Default or Event of Default and its consequences
except a continuing Default or Event of Default in the payment of the Designated
Event Payment or the principal of, or interest on, any Security. When a Default
or Event of Default is waived, it is cured and ceases; but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereon.


                                       33
<PAGE>   40

         SECTION 7.05. Control by Majority. The Noteholders of a majority in
principal amount of the then-outstanding Securities may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on it. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture, is
unduly prejudicial to the rights of other Noteholders, or would involve the
Trustee in personal liability.

         SECTION 7.06. Limitation on Suits. A Noteholder may pursue a remedy
with respect to this Indenture or the Securities only if:

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

         (b) the Noteholders of at least 25% in principal amount of the
    then-outstanding Securities make a request to the Trustee to pursue the
    remedy;

         (c) such Noteholder or Noteholders offer 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 of indemnity; and

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

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

         SECTION 7.07. Rights of Noteholders to Receive Payment. Notwithstanding
any other provision of this Indenture, the right of any Noteholder of a Security
to receive payment of principal and interest on the Security, on or after the
respective due dates expressed in the Security, or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of the Noteholder made pursuant to this
Section.

         SECTION 7.08. Collection Suit by Trustee. If an Event of Default
specified in Section 7.01(a) or (b) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount of principal and interest remaining unpaid on the
Securities and interest on overdue principal and interest and such further
amount as shall be sufficient to cover the costs and, to the extent lawful,
expenses of 





                                       34
<PAGE>   41

collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

         SECTION 7.09. Trustee May File Proofs of Claim. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Noteholders allowed
in any judicial proceedings relative to the Company, its creditors or its
property. Nothing contained herein shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Noteholder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Noteholder thereof, or to authorize the Trustee
to vote in respect of the claim of any Noteholder in any such proceeding.

         SECTION 7.10. 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 for amounts due under Section 8.07 hereof;

         Second: to the Noteholders, for amounts due and unpaid on the
    Securities for principal and interest, ratably, according to the amounts due
    and payable on the Securities for principal and interest, respectively; and

         Third: to the Company.

         Except as otherwise provided in Section 2.12 hereof, the Trustee may
fix a record date and payment date for any payment to Noteholders made pursuant 
to this Section.

         SECTION 7.11. 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 pursuant to Section 7.07 hereof, or a suit by
Noteholders of more than 10% in principal amount of the then-outstanding
Securities.

                                  ARTICLE VIII

                                     Trustee

         SECTION 8.01. 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 their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

         (b) Except during the continuance of an Event of Default: (i) the
Trustee need perform only those duties that are specifically set forth in this
Indenture and no others 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, if required by the terms hereof, 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. During the continuance of an event of Default,
the Trustee may consult with its legal counsel and rely upon advice from such
counsel with respect to legal matters.

         (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that: (i) this paragraph does not limit the effect of
paragraph (b) of this Section 8.01; (ii) the Trustee shall not be liable for any
error of judgment made in good faith by a Trust Officer, unless it is proved
that the Trustee was negligent in ascertaining the pertinent facts 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
7.05 hereof.

         (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section 8.01.

         (e) The Trustee may refuse to perform any duty or exercise any right or
power unless it receives 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 Company. Money held in
trust by the Trustee need not be segregated from other funds except to the
extent required by law.

         SECTION 8.02. Rights of Trustee. (a) The Trustee may rely on any
document believed by it to be genuine and to have been signed or presented by
the proper person. The Trustee need not investigate any fact or matter stated in
the document.





                                       36
<PAGE>   43
         (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.

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

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

         (e) The Trustee shall not be charged with knowledge of any Event of
Default under subsection (c), (d), (e), (f), (g) or (h) of Section 7.01 unless
either (1) a Trust Officer assigned to its corporate trust department shall have
actual knowledge thereof, or (2) the Trustee shall have received notice thereof
in accordance with Section 11.02 hereof from the Company or any holder.

         SECTION 8.03. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or an Affiliate with the same rights it
would have if it were not Trustee. Any Agent may do the same with like rights.
However, the Trustee is subject to Sections 8.10 and 8.11 hereof.

         SECTION 8.04. Trustee's Disclaimer. The Trustee makes no representation
as to the validity or adequacy of this Indenture or the Securities, it shall not
be accountable for the Company's use of the proceeds from the Securities, and it
shall not be responsible for any statement of the Company in the Indenture or
any statement in the Securities (other than its authentication) or for
compliance by the Company with the Registration Agreement.

         SECTION 8.05. 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 Noteholders 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
on any Security, the Trustee may withhold the notice if and so long as a
committee of its Trust Officers in good faith determines that withholding the
notice is in the interests of Noteholders.

         SECTION 8.06. Reports by Trustee to Noteholders. Within 60 days after
the reporting date stated in Section 11.10, the Trustee shall mail to
Noteholders a brief report dated as of such reporting date that complies with
TIA Section 313(a) if and to the extent required by such 




                                     37

<PAGE>   44

Section 313(a). 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 Noteholders shall
be filed with the SEC and each stock exchange on which the Securities are
listed. The Company shall notify the Trustee when the Securities are listed on
any stock exchange.

         SECTION 8.07. Compensation and Indemnity. The Company shall pay to the
Trustee from time to time reasonable compensation for its services hereunder.
The Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable disbursements, expenses and advances incurred or made
by it. Such disbursements and expenses may include the reasonable disbursements,
compensation and expenses of the Trustee's agents and counsel.

         The Company shall indemnify the Trustee against any loss or liability
incurred by it except as set forth in the next paragraph. Promptly after receipt
by the Trustee under this Section of notice of the commencement of any action,
the Trustee will, if a claim in respect thereof is to be made against the
Company under this Section, notify the Company in writing of the commencement
thereof; but the failure so to notify the Company (i) will not relieve it from
liability unless and to the extent it did not otherwise learn of such action and
such failure results in the forfeiture by the Company of substantial rights and
defenses and (ii) will not, in any event, relieve the Company from any
obligations to the Trustee other than the indemnification obligation provided
above. The Company shall be entitled to appoint counsel of the Company's choice
at the Company's expense to represent the Trustee in any action for which
indemnification is sought (in which case the Company shall not thereafter be
responsible for the fees and expenses of any separate counsel retained by the
Trustee or parties except as set forth below); provided, however, that such
counsel shall be reasonably satisfactory to the Trustee. Notwithstanding the
Company's election to appoint counsel to represent the Trustee in an action, the
Trustee shall have the right to employ separate counsel (including local
counsel), and the Company shall bear the reasonable fees, costs and expenses of
such separate counsel (and local counsel) if (i) the use of counsel chosen by
the Company to represent the Trustee would present such counsel with a conflict
of interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the Trustee and the Company and the Trustee shall have
reasonably concluded that there may be legal defenses available to it which are
different from or additional to those available to the Company, (iii) the
Company shall not have employed counsel satisfactory to the Trustee to represent
the Trustee within a reasonable time after notice of the institution of such
action or (iv) the Company shall authorize the Trustee to employ separate
counsel at the expense of the Company; provided further, that the Company shall
not be responsible for the fees and expenses of more than one separate counsel
(together with 



                                       38

<PAGE>   45

appropriate local counsel). The Company will not, without the prior written
consent of the Trustee, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification may be sought hereunder (whether
or not the Trustee is an actual or potential party to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of the Trustee from all liability arising out of such claim, action, suit or
proceeding.

         The Company need not reimburse any expense or indemnify against any
loss or liability incurred by the Trustee through the Trustee's negligence or
bad faith.

         To secure the Company's payment obligations in this Section, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee, except money or property held in trust to pay
principal and interest on particular Securities.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 7.01(g) or (h) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

         SECTION 8.08. 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 by so notifying the Company. The Noteholders of
a majority in principal amount of the then-outstanding Securities may remove the
Trustee by so notifying the Trustee and the Company. The Company may remove the
Trustee if:

         (a) the Trustee fails to comply with Section 8.10 hereof, unless the
    Trustee's duty to resign is stayed as provided in TIA Section 310(b);

         (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 Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the
Noteholders of a majority in principal amount of the then-




                                       39
<PAGE>   46


outstanding Securities may appoint a successor Trustee to replace the successor
Trustee appointed by the Company.

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

         If the Trustee fails to comply with Section 8.10 hereof, unless the
Trustee's duty to resign is stayed as provided in TIA Section 310(b), any
Noteholder who has been a bona fide holder of a Security for at least six months
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 Company. 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 Noteholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 8.07 hereof. Notwithstanding the resignation or
replacement of the Trustee pursuant to this Section 8.08, the Company's
obligations under Section 8.07 hereof shall continue for the benefit of the
retiring trustee with respect to expenses and liabilities incurred by it prior
to such resignation or replacement.

         SECTION 8.09. 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 8.10. Eligibility; Disqualification. This Indenture shall
always have a Trustee who satisfies the requirements of TIA Section 310(a)(1)
and (5). The Trustee shall always have a combined capital and surplus as stated
in Section 11.10 hereof. The Trustee is subject to TIA Section 310(b).

         SECTION 8.11. Preferential Collection of Claims Against Company. 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 IX

                             Discharge of Indenture

         SECTION 9.01. Termination of Company's Obligations. This Indenture
shall cease to be of further effect (except that the Company's obligations under
Sections 8.07 and 9.02 hereof shall survive) when all outstanding Securities
theretofore authenticated and issued have been delivered to the Trustee for
cancellation and the Company has paid all sums payable hereunder.

         Thereupon, the Trustee upon request of the Company, shall acknowledge
in writing the discharge of the Company's obligations under this Indenture,
except for those surviving obligations specified above.

         SECTION 9.02. Repayment to Company. The Trustee and the Paying Agent
shall promptly pay to the Company upon request any excess money or securities
held by them at any time.

         The Trustee and the Paying Agent shall pay to the Company upon written
request any money held by them for the payment of principal or interest that
remains unclaimed for two years after the date upon which such payment shall
have become due; provided, however, that the Company shall have first caused
notice of such payment to the Company to be mailed to each Noteholder entitled
thereto no less than 30 days prior to such payment. After payment to the
Company, the Trustee and the Paying Agent shall have no further liability with
respect to such money and Noteholders entitled to the money must look to the
Company for payment as general creditors unless any applicable abandoned
property law designates another person.

                                    ARTICLE X

                       Amendments, Supplements and Waivers

         SECTION 10.01. Without Consent of Noteholders. The Company and the
Trustee may amend or supplement this Indenture or the Securities without the
consent of any Noteholder:

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

         (b) to comply with Sections 5.13 and 6.01 hereof;

         (c) to provide for uncertificated Securities in addition to
    certificated Securities;




                                       41
<PAGE>   48

         (d) to make any change that does not adversely affect the legal rights
    hereunder of any Noteholder;

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

         (f) to make any change that provides any additional rights or benefits
    to the holders of Securities.

         SECTION 10.02. With Consent of Noteholders. Subject to Section 7.07
hereof, the Company and the Trustee may amend or supplement this Indenture or
the Securities with the written consent (including consents obtained in
connection with any tender or exchange offer for Securities) of the Noteholders
of at least a majority in principal amount of the then-outstanding Securities.
Subject to Sections 7.04 and 7.07 hereof, the Noteholders of a majority in
principal amount of the Securities then outstanding may also by their written
consent (including consents obtained in connection with any tender offer or
exchange offer for Securities) waive any existing Default as provided in Section
7.04 or waive compliance in a particular instance by the Company with any
provision of this Indenture or the Securities. However, without the consent of
each Noteholder affected, an amendment, supplement or waiver under this Section
may not (with respect to any Securities held by a nonconsenting Noteholder):

         (a) reduce the amount of Securities whose Noteholders must consent to
    an amendment, supplement or waiver;

         (b) reduce the rate of or change the time for payment of interest on
    any Security;

         (c) reduce the principal of or change the fixed maturity of any
    Security or alter the redemption provisions with respect thereto;

         (d) make any Security payable in money other than that stated in the
    Security;

         (e) make any change in Section 7.04, 7.07 or 10.02 hereof (this
    sentence);

         (f) waive a default in the payment of the Designated Event Payment or
    principal of, or interest on, any Security (other than as provided in
    Section 7.04);

         (g) waive a redemption payment payable on any Security; or

         (h) make any change that adversely affects the right of Noteholders to
    convert Securities into Common Stock of the Company.


                                       42

<PAGE>   49


         To secure a consent of the Noteholders under this Section 10.02, it
shall not be necessary for the Noteholders to approve the particular form of any
proposed amendment, supplement or waiver, but it shall be sufficient if such
consent approves the substance thereof.

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

         SECTION 10.03. Compliance with Trust Indenture Act. Every amendment to
this Indenture or the Securities shall be set forth in a supplemental indenture
that complies with the TIA as then in effect.

         SECTION 10.04. Revocation and Effect of Consents. Until an amendment,
supplement or waiver becomes effective, a consent to it by a Noteholder of a
Security is a continuing consent by the Noteholder and every subsequent
Noteholder of a Security or portion of a Security that evidences the same debt
as the consenting Noteholder's Security, even if notation of the consent is not
made on any Security. However, any such Noteholder or subsequent Noteholder may
revoke the consent as to such Noteholder's Security or portion of a Security if
the Trustee receives the notice of revocation before the date on which the
Trustee receives an Officers' Certificate certifying that the Noteholders of the
requisite principal amount of Securities have consented to the amendment,
supplement or waiver.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Noteholders entitled to consent to any amendment,
supplement or waiver. If a record date is fixed, then notwithstanding the
provisions of the immediately preceding paragraph, those persons who were
Noteholders at such record date (or their duly designated proxies), and only
those persons, shall be entitled to consent to such amendment, supplement or
waiver or to revoke any consent previously given, whether or not such persons
continue to be Noteholders after such record date. No consent shall be valid or
effective for more than 90 days after such record date unless consents from
Noteholders of the principal amount of Securities required hereunder for such
amendment or waiver to be effective shall have also been given and not revoked
within such 90-day period.

         After an amendment, supplement or waiver becomes effective it shall
bind every Noteholder, unless it is of the type described in any of clauses (a)
through (h) of Section 10.02 hereof. In such case, the amendment or waiver shall
bind each Noteholder who has consented to it and every subsequent Noteholder
that evidences the same debt as the consenting Noteholder's Security.

         SECTION 10.05. Notation on or Exchange of Securities. The Trustee may 
place an appropriate notation about an amendment or waiver on any Security 
thereafter authenticated. 




                                       43

<PAGE>   50

The Company in exchange for all Securities may issue and the Trustee shall
authenticate new Securities that reflect the amendment or waiver.

         SECTION 10.06. Trustee Protected. The Trustee shall sign all
supplemental indentures, except that the Trustee may, but need not, sign any
supplemental indenture that adversely affects its rights. As a condition to
executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modifications thereby of the trust
created by this Indenture, the Trustee shall be entitled to receive (in addition
to those documents required by Section 11.04), and (subject to Section 315 of
the TIA) shall be fully protected in relying upon, an Opinion of Counsel stating
that the execution of such supplemental indenture is authorized or permitted by

                              SABRATEK CORPORATION

                          6% Convertible Note Due 2005


                  1. Interest. SABRATEK CORPORATION, a Delaware corporation (the
"Company"), is the issuer of the 6% Convertible Notes Due 2005 (the "Convertible
Notes"), of which this Convertible Note is a part. The Company promises to pay
interest on the Convertible Notes in cash semiannually on each April 15 and
October 15, commencing on October 15, 1998, to holders of record on the
immediately preceding April 1 and October 1.

                  Interest on the Convertible Notes will accrue from the most
recent date to which interest has been paid, or if no interest has been paid,
from April 14, 1998. Interest will be computed on the basis of a 360-day year of
twelve 30-day months. To the extent lawful, the Company shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue installments of interest (without regard to any applicable grace period)
at the rate borne by the Convertible Notes, compounded annually.

                  2. Method of Payment. The Company will pay interest on the
Convertible Notes (except defaulted interest) to the persons who are registered
holders of the Convertible Notes at the close of business on the record date for
the next interest payment date even though Convertible Notes are canceled after
the record date and on or before the interest payment date. The Noteholder
hereof must surrender Convertible Notes to a Paying Agent to collect principal
payments. The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts. However, the Company may pay principal and interest by check
payable in such money. It may mail an interest check to a holders' registered
address.

                  3. Paying Agent, Registrar and Conversion Agent. The Trustee
will act as Paying Agent, Registrar and Conversion Agent. The Company may change
any Paying Agent, Registrar, or Conversion Agent without prior notice.

                  4. Indenture. The Company issued the Convertible Notes under
an indenture, dated as of April 14, 1998 (the "Indenture"),  between the Company
and LaSalle  National  Bank,  as  Trustee.  The terms of the  Convertible  Notes
include  those stated in the  Indenture  and those made part of the Indenture by
the Trust Indenture Act of 1939 (15 U.S. Code ss.ss.  77aaa-77bbbb) as in effect
on the  date of the  Indenture.  The  Convertible  Notes  are  subject  to,  and
qualified  by, all such  terms,  certain  of which are  summarized  hereon,  and
Noteholders  are referred to the  Indenture and such Act for a statement of such
terms. The Convertible Notes are general

                                       A-4
<PAGE>   60

unsecured obligations of the Company limited to an aggregate principal
amount of $97,750,000. The Indenture does not limit the ability of the Company
or any of its Subsidiaries to incur indebtedness or to grant security interests
or liens in respect of their assets.

                  5. Optional Redemption. The Convertible Notes are not
redeemable at the Company's option prior to April 19, 2001. Thereafter, the
Convertible Notes will be subject to redemption at the option of the Company, in
whole or in part (in any integral multiple of $1,000), at the following
redemption prices (expressed as percentages of the principal amount), if
redeemed during the 12-month period beginning April 15 of the years indicated
(April 19 in the case of the year 2001):

the right of holders of record on the relevant record date to receive interest
due on an interest payment date). On or after the redemption date, interest will

redemption.

                  6. Notice of Redemption. Notice of redemption will be mailed
at least 30 days but not more than 60 days before the redemption date to each
holder of the Convertible Notes to be redeemed at his address of record. The
Convertible Notes in denominations larger than $1,000 may be redeemed in part
but only in integral multiples of $1,000. In the event of a redemption of less
than all of the Convertible Notes, the Convertible Notes will be chosen for
redemption by the Trustee in accordance with the Indenture. Unless the Company
defaults in making such redemption payment, or a Paying Agent is prohibited from
making such payment pursuant to the Indenture, by law or otherwise, interest
ceases to accrue on the Convertible Notes or portions of them called for
redemption on and after the redemption date.

                  If this Convertible Note is redeemed subsequent to a record
date with respect to any interest payment date specified above and on or prior
to such interest payment date, then anyaccrued interest will be paid to the 
person in whose name this Convertible Note is registered at the close of 
business on such record date.

                  7. Mandatory Redemption. The Company will not be required to
make mandatory redemption payments with respect to the Convertible Notes. There
are no sinking fund payments with respect to the Convertible Notes.

                  8. Repurchase at Option of Holder. If there is a Designated
Event, the Company shall be required to offer to purchase on the Designated
Event Payment Date all outstanding Convertible Notes at a purchase price equal
to 100% of the principal amount thereof on the date of purchase, plus accrued
and unpaid interest to the Designated Event Payment Date. Holders of Convertible
Notes that are subject to an offer to purchase will receive a Designated Event
Offer from the Company prior to any related Designated Event Payment Date and
may elect to have such Convertible Notes or portions thereof in authorized
denominations purchased by completing the form entitled "Option of Noteholder To
Elect Purchase" appearing below. Noteholders have the right to withdraw their
election by delivering a written notice of withdrawal to the Company or the
Paying Agent in accordance with the terms of the Indenture.

                  9. Conversion. The holder of any Convertible Note has the
right, exercisable at any time after 90 days following the Issuance Date and
prior to the close of business (New York City time) on the Business Day
immediately preceding the date of the Convertible Note's maturity, to convert
the principal amount thereof (or any portion thereof that is an integral
multiple of $1,000) into shares of Common Stock at the initial Conversion Price
of $40.46 per share, subject to adjustment under certain circumstances, except
that if a Convertible Note is called for redemption, the conversion right will
terminate at the close of business (New York City time) on the Business Day
immediately preceding the date fixed for redemption.

                  To convert a Convertible Note, a holder must (1) complete and
sign a notice of election to convert  substantially in the form set forth below,
(2)  surrender  the  Convertible  Note  to  a  Conversion   Agent,  (3)  furnish
appropriate  endorsements or transfer  documents if required by the Registrar or
Conversion  Agent and (4) pay any  transfer or similar  tax, if  required.  Upon
conversion, no adjustment or payment will be made for interest or dividends, but
if any Noteholder  surrenders a Convertible  Note for conversion after the close
of business on the record date for the payment of an installment of interest and
prior to the  opening of  business  on the next  interest  payment  date,  then,
notwithstanding  such conversion,  the interest payable on such interest payment
date  will be paid to the  registered  holder of such  Convertible  Note on such
record date. In such event,  unless such Security has been called for redemption
on or  prior  to  such  interest  payment  date,  such  Convertible  Note,  when
surrendered for conversion,  must be accompanied by payment in funds  acceptable
to the  Company of an amount  equal to the  interest  payable  on such  interest
payment date on the portion so  converted.  The number of shares of Common Stock
issuable upon conversion of a Convertible Note is determined by dividing the


                                       A-6

<PAGE>   62
principal amount of the Convertible Note converted by the Conversion Price in
effect on the Conversion Date. No fractional shares will be issued upon
conversion but a cash adjustment will be made for any fractional interest.

                  A Convertible Note in respect of which a holder has delivered
an "Option of Noteholder to Elect Purchase" form appearing below exercising the
option of such holder to require the Company to purchase such Convertible Note
may be converted only if the notice of exercise is withdrawn as provided above
and in accordance with the terms of the Indenture. The above description of
conversion of the Convertible Notes is qualified by reference to, and is subject
in its entirety to, the more complete description thereof contained in the
Indenture.

                  10. Registration Agreement. The holder of this Convertible 
Note is entitled to the benefits of a Registration Agreement, dated April 14, 
1998, between the Company and the Initial Purchaser (the "Registration 
Agreement"). Pursuant to the Registration Agreement the Company has agreed
for the benefit of the holders of the Convertible Notes, that (i) it will, at
its cost, within 60 days after the closing of the sale of the Convertible Notes
(the "Closing"), file a shelf registration statement (the "Shelf Registration
Statement") with the Securities and Exchange Commission (the "Commission") with
respect to resales of the Convertible Notes and the Common Stock issuable upon
conversion thereof, (ii) the Company will use its best efforts to ensure that
within 120 days after the Closing, such Shelf Registration Statement shall be
declared effective by the Commission and (iii) the Company will use its best
efforts to keep such Shelf Registration Statement continuously effective under
the Securities Act until the earliest of (a) the second anniversary of the date
of the Closing, (b) the date on which the Convertible Notes or the Common Stock
issuable upon conversion thereof may be sold pursuant to paragraph (k) of Rule
144 (or any successor provision) promulgated by the Commission under the
Securities Act and (c) the date as of which all the Convertible Notes or the
Common Stock issuable upon conversion thereof have been sold pursuant to such
Shelf Registration Statement (the "Shelf Registration Period"). If the Company
fails to comply with clause (i) above then, at such time, the per annum
interest rate on the Convertible Notes will increase by 25 basis points. Such
increase will remain in effect until the date on which such Shelf Registration
Statement is filed, on which date the interest rate on the Convertible Notes
will revert to the interest rate originally borne by the Convertible Notes plus
any increase in such interest rate pursuant to the following sentence. If the
Shelf Registration Statement is not declared effective as provided in clause
(ii) above (other than as a result solely of actions of any holders of
securities covered by such Shelf Registration Statement), then, at such time
and on each date that would have been the successive 30th day following such
time, the per annum interest rate on the Convertible Notes (which interest rate
will be the original interest rate on the Convertible Notes plus any increase
or



                                       A-7

<PAGE>   63

increases in such interest rate pursuant to the preceding sentence and this
sentence) will increase by an additional 25 basis points; provided that the
interest rate will not increase by more than 50 basis points pursuant to this
sentence and will not increase by more than 75 basis points pursuant to this
sentence and the preceding sentence. Such increase or increases will remain in
effect until the date on which such Shelf Registration Statement is declared
effective, on which date the interest rate on the Convertible Notes will revert
to the interest rate originally borne by the Convertible Notes. Pursuant to
clause (iii) above, however, if the Company fails to keep the Shelf Registration
Statement continuously effective for the period specified above (other than as a
result solely of actions of any holders of securities covered by such Shelf
Registration Statement), then at such time as the Shelf Registration Statement
is no longer effective and on each date thereafter that is the successive 30th
day subsequent to such time and until the earlier of (i) the date that the Shelf
Registration Statement is again deemed effective or (ii) the termination of the
Shelf Registration Period, the per annum interest rate on the Convertible Notes
will increase by an additional 25 basis points; provided, however, that the
interest rate will not increase by more than 50 basis points pursuant to this
sentence. For any period during which the per annum interest rate on the Notes
is increased pursuant to this paragraph, each holder of restricted Common Stock
issued upon conversion of the Notes shall be entitled to receive liquidated
damages from the Company as follows: (i) for every 25 basis points by which such
interest rate is increased pursuant to this paragraph, such liquidated damages
shall accrue at a rate equal to $2.50 per annum per 24.7158 shares of Common
Stock (subject to adjustment in the event of a stock split, stock recombination,
stock dividend and the like); and (ii) any liquidated damages which have accrued
pursuant to this paragraph prior to the record date relating to any interest
payment date shall be payable on such interest payment date to the holders of
record on such record date. For purposes of the foregoing, restricted Common
Stock shall not include any shares of Common Stock which (i) may be sold
pursuant to paragraph (k) of Rule 144 (or any successor provision) promulgated
by the Commission under the Securities Act or (ii) have been sold pursuant to
the Shelf Registration Statement.

                  Pursuant to the Registration Agreement, the Company may 
suspend the use of the prospectus which is a part of the Shelf Registration
Statement for a period not to exceed 30 days in any three-month period or three
periods not to exceed an aggregate of 90 days in any twelve-month period under
certain circumstances. The holders of Convertible Notes will not be entitled to
additional interest as set forth in the preceding paragraph solely because of
such suspension.

                  11. Denominations, Transfer, Exchange and Replacement. The 
Convertible Notes are in registered form, without coupons, in denominations of 
$1,000 and integral multiples of $1,000. The transfer of Convertible Notes may 
be registered, and Convertible Notes may be 







                                       A-8
<PAGE>   64

exchanged, as provided in the Indenture. The Registrar may require a Noteholder,
among other things, to furnish appropriate endorsements and transfer documents
and to pay any taxes and fees required by law or permitted by the Indenture. The
Registrar need not exchange or register the transfer of any Convertible Note or
portion of a Convertible Note selected for redemption (except the unredeemed
portion of any Convertible Note being redeemed in part). Also, it need not
exchange or register the transfer of any Convertible Note for a period of 15
days before a selection of Convertible Notes to be redeemed. Replacement
Convertible Notes for lost, stolen or mutilated Convertible Notes may be issued
in accordance with the terms of the Indenture.

                  12. Persons Deemed Owners. The registered Noteholder of a
Convertible Note may be treated as its owner for all purposes.

                  13. Unclaimed Money. If money for the payment of principal or
interest remains unclaimed for two years, the Trustee and the Paying Agent shall
pay the money back to the Company at its request. After that, Noteholders of
Convertible Notes entitled to the money must look to the Company for payment,
unless an abandoned property law designates another person, and all liability of
the Trustee and such Paying Agent with respect to such money shall cease.

                  14. Defaults and Remedies. The Convertible Notes shall have
the Events of Default as set forth in Section 7.01 of the Indenture. Subject to
certain limitations in the Indenture, if an Event of Default occurs and is
continuing, the Trustee by notice to the Company or the Noteholders of at least
25% in aggregate principal amount of the then-outstanding Convertible Notes by
notice to the Company and the Trustee may declare all the Convertible Notes to
be due and payable immediately, except that in the case of an Event of Default
arising from certain events of bankruptcy or insolvency, all unpaid principal
and interest accrued on the Convertible Notes shall become due and payable
immediately without further action or notice.

                  The Noteholders of a majority in principal amount of the
Convertible Notes then outstanding by written notice to the Trustee may rescind
an acceleration and its consequences if the rescission would not conflict with
any judgment or decree and if all existing Events of Default have been cured or
waived except nonpayment of principal or interest that has become due solely
because of the acceleration. Noteholders may not enforce the Indenture or the
Convertible Notes except as provided in the Indenture. Subject to certain
limitations, Noteholders of a majority in principal amount of the
then-outstanding Convertible Notes issued under the Indenture may direct the
Trustee in its exercise of any trust or power. The Company must furnish
compliance certificates to the Trustee annually. The above description of Events
of Default and remedies is qualified by reference to, and subject in its
entirety to, the more complete description thereof contained in the Indenture.

<PAGE>   65






                  15. Amendments, Supplements and Waivers. Subject to certain
exceptions, the Indenture or the Convertible Notes may be amended or
supplemented with the consent of the Noteholders of at least a majority in
principal amount of the then-outstanding Convertible Notes (including consents
obtained in connection with a tender offer or exchange offer for Convertible
Notes), and any existing default may be waived with the consent of the
Noteholders of a majority in principal amount of the then-outstanding
Convertible Notes, including consents obtained in connection with a tender offer
or exchange offer for Convertible Notes. Without the consent of any Noteholder,
the Indenture or the Convertible Notes may be amended, among other things, to
cure any ambiguity, defect or inconsistency, to provide for assumption of the
Company's obligations to Noteholders, to make any change that does not adversely
affect the rights of any Noteholder, to qualify the Indenture under the TIA, or
to comply with the requirements of the SEC in order to maintain the
qualification of the Indenture under the TIA.

                  16. Trustee Dealings with the Company. The Trustee, in its
individual or any other capacity, may become the owner or pledgee of the
Convertible Notes and may otherwise deal with the Company or an Affiliate with
the same rights it would have, as if it were not Trustee, subject to certain
limitations provided for in the Indenture and in the TIA. Any Agent may do the
same with like rights.

                  17. No Recourse Against others. A director, Officer, employee
or stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Convertible Notes or the Indenture or for
any claim based on, in respect of or by reason of such obligations or their
creation. Each Noteholder, by accepting a Convertible Note, waives and releases
all such liability. The waiver and release are part of the consideration for the
issue of the Convertible Notes.

                  18. Governing Law. THE INTERNAL LAWS OF THE STATE OF NEW YORK
SHALL GOVERN THE INDENTURE AND THE CONVERTIBLE NOTES WITHOUT REGARD TO CONFLICT
OF LAW PROVISIONS THEREOF.

                  19. Authentication. The Convertible Notes shall not be valid
until authenticated by the manual signature of an authorized officer of the
Trustee or an authenticating agent.

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

     Re:  Registration Statement on Form S-3
 
Ladies and Gentlemen:
 
     You have requested our opinion with respect to the registration by Sabratek
Corporation (the "Company") pursuant to a Registration Statement on Form S-3
(the "Registration Statement") under the Securities Act of 1933, as amended (the
"Act"), of $85,000,000 principal amount of 6% Convertible Notes due 2005 (the
"Notes") and the shares of Common Stock issuable upon conversion of the Notes
(the "Shares", together with the Notes, the "Securities").
 
     In so acting, we have examined originals or copies, certified or otherwise
identified to our satisfaction, of such documents, corporate records,
certificates of public officials and other instruments and have conducted such
other investigations of fact and law as we have deemed relevant and necessary to
form a basis for the opinions hereinafter expressed. In conducting such
examination, we have assumed (i) that all signatures are genuine, (ii) that all
documents and instruments submitted to us as copies conform with the originals,
and (iii) the due execution and delivery of all documents where due execution
and delivery are a prerequisite to the effectiveness thereof. As to any facts
material to this opinion, we have relied upon statements and representations of
officers and other representatives of the Company and certificates of public
officials and have not independently verified such facts.
 
     Based upon the foregoing, it is our opinion that the Notes have been duly
authorized and issued and that the Shares issuable upon the proper conversion of
the Notes have been duly authorized will be validly issued, fully paid and
non-assessable when issued upon conversion of the Notes.
 
     We express no opinion as to the laws of any jurisdiction other than the
State of Illinois and the United States of America. Insofar as the foregoing
opinion relates to matters that would be controlled by the substantive laws of
any jurisdiction other than the United States of America or the State of
Illinois, we have assumed that the substantive laws of such jurisdiction conform
in all respects to the internal laws of the State of Illinois.
 
     We hereby consent to the reference to our firm in the Registration
Statement relating to the registration of the Securities
 
                                          Very truly yours,
 
                                          ROSS & HARDIES

                                     Loan upon acceleration due to the

                                     the Prime Rate.

                         2.3.2       EQUIPMENT TERM LOANS. During the period the
                                     Equipment Term Loans are governed by
                                     Section 2.1.3.2.1, the principal amount

                                     Facility will bear interest at a varying
                                     interest rate equal to the Prime Rate. Upon
                                     the occurrence of the events set forth in

                                     selected by Borrower on or before the date
                                     or dates of the occurrence of such events:

                                 2.3.2.1  A varying rate equal to the Prime 
                                          Rate; or
 
                                 2.3.2.2  A fixed rate equal to 250 basis points
                                          per annum plus the then current
                                          five  year Treasury Bill yield, as
                                          stated in  the Wall Street Journal
                                          (Midwest  Edition) on the day of
                                          funding.

                         2.3.3   COMPUTATION OF INTEREST. All interest shall
                                 be computed on the basis of a year of 360      
                                 days and actual days elapsed, and shall be
                                 payable as provided in Section 3.2 of this
                                 Agreement. Any change in any interest rate
                                 applicable to any of the Liabilities based on
                                 the Prime Rate shall be effective as of the
                                 effective date stated in the announcement by
                                 the Lender of such change in the Prime Rate.
                                 In addition, for purposes of calculating
                                 interest payable on the Revolving Loan,
                                 payments of principal thereon shall be applied
                                 to the outstanding principal balance of the
                                 Revolving Loan upon receipt of such payments
                                 by Lender in immediately available funds.

                         2.3.4   DEFAULT RATES. Upon the occurrence and
                                 during the continuance of an Event of
                                 Default, Borrower shall pay Lender interest on
                                 the outstanding Liabilities, including
                                 principal, interest, fees and reimbursable
                                 expenses, at a rate (the "Default Rate"),
                                 equal to the interest rate provided in the
                                 applicable Note, plus three percent (3%).  In
                                 no event whatsoever shall the rate of interest
                                 paid by Borrower under this Agreement or any
                                 of the Ancillary Agreements exceed the maximum
                                 amount permissible under any law which a court
                                 of competent jurisdiction shall, in a final
                                 determination and following exhaustion of all
                                 appeals, deem applicable hereto. In the event
                                 that such a court determines that Lender has
                                 received interest hereunder in excess of the
                                 maximum rate permitted by any such law, (i)
                                 Lender shall apply the excess amount of
                                 interest paid by Borrower to any unpaid
                                 principal owed by Borrower to Lender or, if
                                 the amount of such excess exceeds the unpaid
                                 balance of such principal, Lender shall
                                 promptly refund such excess interest to
                                 Borrower, and (ii) the provisions hereof shall
                                 be deemed amended to provide for such
                                 permissible rate. All sums paid, or agreed to
                                 be paid, by Borrower which are, or hereafter
                                 may be construed to be, compensation for the
                                 use, forbearance or detention of money shall,
                                 to the extent permitted by applicable law, be
                                 amortized, prorated, spread and allocated
                                 throughout the full term of all such
                                 Indebtedness until the Indebtedness is paid in
                                 full.

                                     such Over-Advance.

                                     maintaining its Loans, the Letter of Credit
                                     or its obligation to make Loans hereunder,
                                     then, within 15 days after receipt by

                                     increased capital which Lender determines
                                     is attributable to this Agreement, its
                                     Loans, or its obligation to make Loans
                                     hereunder. "Change" means (i) any change

                         2.8.3       LENDER STATEMENTS: SURVIVAL OF INDEMNITY.
                                     Lender shall use its best efforts to
                                     notify Borrower in writing of any Change,
                                     law, policy, rule, guideline or directive
                                     giving rise to such demand for
                                     compensation not later than ninety (90)
                                     days following the date upon which Lender
                                     knows of such Change, law, policy, rule,
                                     guideline or directive. Any demand for
                                     compensation pursuant to this Agreement
                                     shall be in writing and shall state the
                                     amount due, if any, and shall set forth in
                                     reasonable detail the calculations upon
                                     which Lender determined such amount. Such
                                     written demand shall be rebuttably
                                     presumed correct for all purposes. The
                                     obligations of the Borrower under this
                                     Section 2.8, shall survive payment of the
                                     Liabilities and termination of this
                                     Agreement.

3.0          PAYMENTS

             3.1         BORROWER'S LOAN ACCOUNT. Lender shall maintain a loan
                         account ("Loan Account") on its books in which shall be
                         recorded (i) all loans and advances made by Lender to
                         Borrower pursuant to this Agreement, (ii) all payments
                         made by Borrower on all such loans and advances and
                         (iii) all other appropriate debits and credits as
                         provided in this Agreement, including, all fees,
                         charges, expenses and interest. All entries in
                         Borrower's Loan Account and other accounts shall be
                         made in accordance with Lender's customary accounting
                         practices as in effect from time to time.

             3.2         PAYMENT TERMS. All of the Liabilities shall be payable
                         to Lender at the address set forth in Section 8.10 of

                         this Agreement or in the Ancillary Agreement or (b) in
                         the case of acceleration of the Liabilities, principal
                         on the Term Loans and interest on the Liabilities shall
                         be payable monthly on the first day of each month.
                         Unless otherwise provided in this Agreement or the
                         Ancillary Agreements, all other payments shall be
                         payable within five (5) days of Lender's demand. At
                         Lender's sole discretion, such payment may be made by a
                         debit to Borrower's demand deposit account with Lender,
                         and fees, costs, expenses and similar charges shall
                         also be payable monthly by such debits.

             3.3         CASH COLLATERAL ACCOUNT. Borrower shall use Lender as
                         its exclusive depository and disbursement bank for all
                         of its accounts. Borrower shall establish general
                         accounts with Lender in Borrower's names. Borrower and
                         any of its Affiliates, shareholders, directors,
                         officers, employees, agents or those Persons acting for
                         or in concert with Borrower shall, acting as Trustee
                         for Lender, receive any monies, checks, notes, drafts
                         or any other payment relating to and/or proceeds of
                         Collateral which come into their possession or under
                         their control and immediately upon receipt thereof,
                         shall remit the same or cause the same to be remitted
                         to Lender for deposit into Borrower's general accounts
                         with Lender. Borrower hereby agrees that, upon the
                         occurrence of any Event of Default, Lender shall have
                         the right, without the necessity or prior or
                         contemporaneous notice, to set-off against any portion
                         and/or all of the Liabilities all payments made to and
                         all funds deposited in Borrower's accounts of any kind,
                         or funds otherwise received by Lender. Borrower agrees
                         to pay fees, costs and expenses which Lender charges or
                         incurs in connection with opening, servicing, operating
                         and maintaining Borrower's accounts with Lender in
                         accordance with Lender's standard fee schedule, and
                         such amounts will constitute part of the Liabilities
                         and shall be secured by any Collateral.

             3.4         APPLICATION OF PAYMENTS AND COLLECTIONS. Borrower
                         irrevocably waive the right to direct the application
                         of payments and collections received by Lender from or
                         on behalf of Borrower, and Borrower agrees that Lender
                         shall have the continuing, exclusive right to apply and
                         reapply any and all such payments and collections
                         against the Liabilities in such manner as Lender may
                         deem appropriate, notwithstanding any term or provision
                         hereof or any entry by Lender upon any of its books and
                         records. Unless Lender in its discretion determines
                         otherwise, amounts credited to the Loan Account shall
                         be applied to the principal balance of the Revolving
                         Loan, and when the outstanding principal balance of the
                         Revolving Loan is equal to zero (0), any amount
                         remaining unapplied shall be credited to Borrower's
                         demand deposit account with Lender. To the extent that
                         Borrower make a payment or payments to Lender or Lender
                         receives any 


                                      (15)
<PAGE>   22
                         payment or proceeds of the Collateral for Borrower's
                         benefit, which payment(s) or proceeds or any part
                         thereof are subsequently invalidated,  declared to be
                         fraudulent or preferential, set aside and/or required
                         to be repaid to a trustee, receiver, custodian or any
                         other party under any bankruptcy act, state or federal
                         law, common law or equitable cause, then, to the
                         extent of such payment or proceeds received, the
                         Liabilities or part thereof intended to be satisfied
                         shall be revived and shall continue in full force and
                         effect, as if such payments or proceeds have not been
                         received by Lender.
                        
             3.5         STATEMENTS. Until such time as Lender shall have
                         rendered to Borrower written statements of account as
                         provided herein, the balance in Borrower's Loan
                         Account, as set forth on Lender's most recent
                         statement, shall be rebuttably presumptive evidence of
                         the amounts due and owing to Lender by Borrower. Not
                         less than ten (10) Business Days nor more than twenty
                         (20) Business Days after the final day of each calendar
                         month, Lender shall render to Borrower a statement
                         setting forth the balance of Borrower Loan Account,
                         including principal, interest, expenses and fees. Each
                         such statement shall be subject to subsequent
                         adjustment by Lender and Lender's right to reapply
                         payments in accordance with Section 3.4 of this
                         Agreement but shall, absent manifest errors or
                         omissions, be presumed correct and conclusively binding
                         upon Borrower and shall constitute an account stated
                         unless, within sixty (60) days after receipt of any
                         statement from Lender, Borrower shall deliver to Lender
                         written objection thereto specifying the error or
                         errors, if any, contained in such statement. Any such
                         objection by Borrower shall toll the sixty (60) day
                         period referred to in the preceding sentence during the
                         period reasonably required to resolve such objection.

4.0          WARRANTIES AND REPRESENTATIONS

             4.1         GENERAL WARRANTIES AND REPRESENTATIONS. Borrower
                         warrants and represents to Lender that:

                                     incorporation, as represented at the
                                     beginning of this Agreement, and is
                                     qualified or licensed to do business in all
                                     other countries, states and provinces where
                                     the failure to be so qualified and/or
                                     licensed would have a material adverse
                                     effect on Borrower;

                         4.1.2       Borrower has not used, during the five (5)
                                     year period preceding the date of this

                         4.1.3       Borrower has the right and power and is
                                     duly authorized and empowered to enter
                                     into, execute, deliver and perform this
                                     Agreement and the Ancillary Agreements;

                                     execution or performance, the lapse of
                                     time, the giving of notice or otherwise,
                                     constitute a violation of any applicable
                                     law, rule or regulation or a breach of any
                                     provision contained in any Borrower's
                                     Certificate of Incorporation or By-Laws or
                                     contained in any agreement, instrument,
                                     indenture or other document to which any
                                     Borrower is now a party or by which it is
                                     bound;

                         4.1.5       Borrower's uses of the proceeds of any
                                     advances and readvances made by Lender to
                                     Borrower pursuant to this Agreement are,
                                     and will continue to be, legal and proper
                                     corporate uses (duly authorized by its
                                     Board of Directors, if necessary pursuant
                                     to applicable corporate law, rule or
                                     regulation) and such uses are consistent
                                     with all applicable laws and statutes, as
                                     in effect as of the date hereof;

                         4.1.6       To the best of Borrower's knowledge,
                                     Borrower has, and is current and in good
                                     standing with respect to, all governmental
                                     approvals, permits, certificates,
                                     inspections, consents and franchises
                                     necessary to conduct or to continue to
                                     conduct its present or intended business as
                                     heretofore conducted by it or in a manner
                                     similar to that of the previous owner of
                                     the business or of other Persons engaged in
                                     the same or similar businesses and to own
                                     or lease and operate its properties as now
                                     owned or leased and operated by it or by
                                     the previous owner of those properties;

                         4.1.7       To the best of Borrower's knowledge, none
                                     of said approvals, permits, certificates,
                                     consents or franchises contain any term,
                                     provision, condition or limitation more
                                     burdensome than such as are generally

                         and are no less favorable to Borrower than would obtain

                         specific personal property so acquired, the aggregate
                         of said leases and indebtedness does not exceed
                         $100,000 at any time outstanding, and the transaction
                         does not otherwise violate any other provision hereof;

             5.2.10      Incur any Indebtedness for borrowed money (other than
                         the Liabilities) from any Person;

             5.2.11      Change its name, business structure or identity, or add

             5.2.12      Engage in any line of business materially different
                         from that previously engaged in by Borrower;

             5.2.13      Change or relocate its chief executive office or
                         principal place of business; and

     5.3     PAYMENT OF CHARGES. Subject to the provisions of Section 5.4 of
             this Agreement, Borrower shall pay promptly when due all of the
             Charges. In the event Borrower, at any time or times hereafter,
             shall fail to pay the Charges or to promptly obtain the
             satisfaction of such Charges under circumstances where said Section
             5.4 does not relieve Borrower from doing so, Borrower shall so
             advise Lender thereof in writing and Lender may, without waiving or
             releasing any obligation or liability of Borrower hereunder or any
             Default or Event of Default, in its sole and absolute discretion,
             at any time or times thereafter, make such payment or any part
             thereof, (but shall not be obligated so to do) or obtain such
             satisfaction and take any other action with respect thereto which
             Lender deems advisable. All sums so paid by Lender and any
             expenses, including reasonable attorneys' fees, court costs,
             expenses and other charges relating thereto, shall be payable, upon
             demand, by Borrower to Lender and shall be additional Liabilities
             hereunder secured by the Collateral.

     5.4     CONTESTING CHARGES. Notwithstanding anything to the contrary
             herein, Borrower may dispute any Charges without prior payment
             thereof, even if such non-payment may cause a lien to attach to any
             Borrower's assets, provided that Borrower shall give Lender notice
             of such dispute and shall be diligently contesting the same in good
             faith, with due diligence and by an appropriate proceeding and
             there is no danger of a loss or forfeiture of any of Borrower's
             assets, and provided further that, if the same are in excess of
             Twenty-Five Thousand Dollars ($25,000) in the aggregate at any time
             or times hereafter, Borrower shall give Lender such additional
             collateral and assurances as Lender, in its sole discretion, deems
             necessary under the circumstances.

     5.5     INSURANCE: PAYMENT OF PREMIUMS. All policies of insurance required
             hereunder shall be in form and with insurers recognized as adequate
             by prudent business persons and all such policies shall be in such
             amounts as may be satisfactory to Lender. Borrower shall deliver to
             Lender the original (or certified copy) of each policy of insurance
             and evidence of payment of all premiums therefor. [Such policies of
             insurance shall contain an endorsement, in form and substance
             acceptable to Lender, naming Lender as additional insured or loss
             payee. Such endorsement shall provide that the insurance companies
             will give Lender at least thirty (30) days' prior notice before any
             such policy shall be altered or canceled 


                                      (25)
<PAGE>   32

             and that no act or default of Borrower or any other Person shall
             affect the right of Lender to recover under such policy in case of
             loss or damage.] If Borrower shall fail to obtain or maintain any
             of the policies required by this Agreement or to pay any premium
             relating thereto, then Lender, without waiving or releasing any
             obligation or default by Borrower hereunder, may (but shall be
             under no obligation to do so) obtain and maintain such policies of
             insurance and pay such premium and take any other action with
             respect thereto which Lender deems advisable. All sums so disbursed
             by Lender, including reasonable attorneys' fees, court costs,
             expenses and other charges relating thereto, shall be payable, on
             demand, by Borrower to Lender and shall be additional Liabilities
             hereunder secured by the Collateral.

     5.6     SURVIVAL OF OBLIGATIONS UPON TERMINATION OF AGREEMENT. Except as
             otherwise expressly provided for in this Agreement and in the
             Ancillary Agreements, no termination or cancellation (regardless of
             cause or procedure) of this Agreement or the Ancillary Agreements
             shall in any way affect or impair the powers, obligations, duties,
             rights, and liabilities of Borrower or Lender in any way or respect
             relating to any transaction or event occurring prior to such
             termination or cancellation, any Collateral, or any of the
             undertakings, agreements, covenants, warranties and representations
             of Borrower or Lender contained in this Agreement or the Ancillary
             Agreements. All such undertakings, agreements, covenants,
             warranties and representations shall survive such termination or
             cancellation.

                         applicable grace period; or

             6.1.2       Borrower fails or neglect to perform, keep or observe

                         hereafter existing, to which Borrower is a party, but
                         only if that default has a material effect upon the
                         operation of Borrower's business;

             6.1.4       An event of default shall occur and be continuing after

                                     materially adverse.

                         continuance of an Event of Default, if Borrower shall
                         have granted to Lender a security interest in all
                         assets of Borrower hereunder, Lender shall have the

                                     or giving Borrower notice and opportunity
                                     for a hearing on the validity of Lender's

                                     conducted. Lender shall have the right to
                                     conduct such sales on any Borrower's
                                     premises or elsewhere and shall have the

                                     nature, as it pertains to the Collateral,
                                     in advertising for sale and selling any

                                     may purchase all or any part of the
                                     Collateral at public or, if permitted by
                                     law, private sale and, in lieu of actual
                                     payment of such purchase price, may set
                                     off the amount of such price against the
                                     Liabilities. The proceeds realized from
                                     the sale of any Collateral shall be
                                     applied first to the reasonable costs,

                                     and expenses incurred by Lender for
                                     collection and for acquisition,
                                     completion, protection, removal, storage,
                                     sale and delivery of the Collateral;
                                     second to interest due upon any of the
                                     Liabilities; and third to the principal of
                                     the Liabilities. If any deficiency shall
                                     arise, Borrower shall remain liable to
                                     Lender therefor.
        
             6.4         NOTICE. Any notice required to be given by Lender of a
                         sale, lease, other disposition of the Collateral or any
                         other intended action by Lender, which is deposited in
                         the United States mail, postage prepaid and duly

                                     determined, would have a material adverse
                                     effect on the financial operations of
                                     Borrower taken as a whole; and

                         execution of this Agreement and the initial field

                         the performance of such legal services.

             8.3         NO WAIVER BY LENDER. Lender's failure, at any time or
                         times hereafter, to require strict performance by
                         Borrower of any provision of this Agreement shall not
                         constitute a waiver, or affect or diminish any right of
                         Lender thereafter to demand strict compliance and
                         performance therewith. Any suspension or waiver by
                         Lender of a Default or Event of Default by Borrower
                         under this Agreement or the Ancillary Agreements shall
                         not suspend, constitute a waiver of or affect any other
                         Default or Event of Default by Borrower under this
                         Agreement or Ancillary Agreements, whether the same is
                         prior or subsequent thereto and whether of the same or
                         of a different type. None of the undertakings,
                         agreements, warranties and covenants of Borrower
                         contained in this Agreement or the Ancillary Agreements
                         and no Default or Event of Default by the Borrower
                         under this Agreement or the Ancillary Agreements shall
                         be deemed to have been suspended or waived by Lender,
                         unless such suspension or waiver is by an instrument in
                         writing signed by an officer of Lender and directed to
                         Borrower specifying such suspension or waiver.

             8.4         SEVERABILITY. Wherever possible, each provision of this
                         Agreement shall be interpreted in such manner as to be
                         effective and valid under applicable law, but if any
                         provision of this Agreement shall be prohibited by or
                         invalid under applicable law, such provision shall be
                         ineffective to the extent of such prohibition or
                         invalidity, without invalidating the remainder of such
                         provision or the remaining provisions of this
                         Agreement.

             8.5         PARTIES; ENTIRE AGREEMENT. This Agreement and the
                         Ancillary Agreements shall be binding upon and inure to
                         the benefit of the successors and assigns of Borrower
                         and Lender. Borrower's successors and assigns shall
                         include, without limitation, a trustee, receiver or
                         debtor-in-possession of or for Borrower. Nothing
                         contained in this Section 8.5 shall be deemed to modify
                         Section 12.2 of this Agreement. This Agreement is the
                         complete statement of the agreement by and between
                         Borrower and the Lender and supersedes all prior
                         negotiations, understandings and representations
                         between them with respect to the subject matter of this
                         Agreement.

             8.6         CONFLICT OF TERMS. The provisions of the Ancillary
                         Agreements are incorporated in this Agreement by this
                         reference thereto. Except as otherwise provided in this

                         provision contained in this Agreement is in conflict
                         with, or inconsistent with, any provision in the
                         Ancillary Agreements, the provision contained in this
                         Agreement shall govern and control.

             8.7         WAIVERS BY BORROWER. Except as otherwise provided for
                         in this Agreement, Borrower waives (i) presentment,

                         compromise, settlement, extension or renewal of any or
                         all commercial paper, contract rights, documents,
                         instruments, chattel paper and guaranties at any time
                         held by Lender on which Borrower may in any way be
                         liable and hereby ratify and confirm whatever Lender
                         may do in this regard; (ii) all rights to notice and a
                         hearing prior to Lender's taking possession or control

                         any Collateral or any bond or security which might be
                         required by any court prior to allowing Lender to
                         exercise any of Lender's remedies; and (iii) the
                         benefit of all valuation, appraisement, extension and

                         Agreement.

             8.8         GOVERNING LAW. This Agreement shall be interpreted, and
                         the rights and liabilities of the parties hereto
                         determined, in accordance with the internal laws (as

             8.11        DELEGATION OF DUTIES AND GRANT OF AUTHORITY. Lender may
                         perform any of its duties under this Agreement or
                         under the Ancillary Agreements by or through agents or 
                         attorneys-in-fact and shall be entitled to advice of
                         counsel concerning all matters pertaining to such
                         duties. In such capacity, such agent or
                         attorney-in-fact shall have the right to undertake,
                         exercise and enforce, on behalf of Lender, all duties,
                         rights, demands and acts of discretion of Lender
                         provided for in, or in any way related to, this
                         Agreement or the Ancillary Agreements and to receive
                         all payments, notices and requests from Borrower on
                         behalf of and for the account of Lender that are
                         provided for in, or in any way related to, this
                         Agreement or the Ancillary Agreements to "Lender"
                         shall be deemed to mean a reference to such agent or
                         attorney in fact, as agent for Lender, as well as a
                         reference to Lender.

                         fees and document search fees. Lender shall deduct
                         these expenses from Borrower's loan proceeds at the
                         time of closing. Payment of such expenses shall not be
                         credited to any of the Liabilities.

             8.13        SECTION TITLES. The section titles and Table of
                         Contents contained in this Agreement are and shall be

                                 REVOLVING NOTE

$8,000,000.00                                                    March 26, 1997
Chicago, Illinois

            FOR VALUE RECEIVED, Sabratek Corporation, a Delaware corporation
("Borrower"), unconditionally promises to pay to the order of LaSalle Bank NI
("Lender"), at its offices at 3201 North Ashland Avenue, Chicago, Illinois, or
at such other place or places as Lender may from time to time designate in
writing, an amount not to exceed the principal sum of EIGHT MILLION DOLLARS
($8,000,000.00), together with interest payable on the principal balance from
time to time remaining unpaid. Notwithstanding anything to the contrary
contained herein, all unpaid principal, interest and other costs, charges or
amounts owing hereunder shall be due and shall be paid on April 30, 1999.

             Principal and interest payments shall be due and payable as set
forth in that certain Credit Agreement dated March 26, 1997 by and among
Borrower and Lender (the "Loan Agreement"), at Lender's offices or wherever
Lender shall direct in writing. All terms of the Loan Agreement are hereby
incorporated herein. The Loan Agreement, among other things, contains provisions
for default, acceleration of amounts owing in certain circumstances, and
requests for advances under this instrument. Capitalized terms used herein and
not otherwise defined shall have the meanings given them in the Loan Agreement.

             Interest shall be computed on the basis of a 360-day year for the
actual number of days elapsed, and shall be at a varying rate per annum equal to
the Prime Rate. Upon and during the continuance of an Event of Default, interest
shall be at a varying rate per annum equal to three percent (3%) plus the Prime
Rate. The "Prime Rate" shall mean the interest rate per annum from time to time
announced and made effective by Lender at its office in Chicago, Illinois, as
the Prime Rate, or, as the case may be, the base, reference or other similar
rate then designated by Lender for commercial loan reference purposes, it being
understood that such rate is a reference rate, not necessarily the lowest
interest rate charged by Lender or others to their respective customers, and as
established from time to time serves as the basis upon which effective rates of
interest are calculated for those loans making reference thereto.

             Borrower warrants and represents to Lender that Borrower has used
and will continue to use the loans and advances represented by this Note solely
for proper business purposes, and consistent with all applicable laws and
statues. Borrower further warrants and represents to Lender and covenants with
Lender that Borrower is not in the business of extending credit for the purpose
of purchasing or carrying margin stock (within the meaning of Regulation U
issued by the Board of Governors of the Federal Reserve System), and no part of
the loan represented by this Note has been or will be used to purchase or carry
any margin stock or to extend credit to others for the purpose of purchasing or
carrying any margin stock.

             Upon and after the occurrence and during the continuance of an
Event of Default under 


                                      A-1
<PAGE>   46

the Loan Agreement (a) at the option of Lender, the entire unpaid amount of all
the Liabilities shall become immediately due and payable without demand, notice
or legal process of any kind; and (b) Lender may, at its option, without demand,
notice or legal process of any kind, exercise any and all rights and remedies
granted to it by the Loan Agreement or by any Ancillary Agreement or any other
rights and remedies available to it under the Code or other law of the State of
Illinois.

             Upon and after the occurrence of and during the continuance of an
Event of Default, Borrower waives the benefit of any law that would otherwise
restrict or limit Lender in the exercise of its right, which is hereby
acknowledged, to set off at any time hereafter any indebtedness owing from
Lender to Borrower. Borrower does hereby assign and transfer to Lender any and
all cash, negotiable instruments, documents of title, chattel paper, securities,
certificates of deposit, deposit accounts, other cash equivalents and other
assets of Borrower in the possession or control of Lender for any purpose,
including application to the satisfaction of any or all of the Liabilities.

             Borrower waives presentment, demand and protest, notice of protest
and notice of presentment. Any failure of Lender to exercise any right available
hereunder or otherwise shall not be construed as a waiver of the right to
exercise the same or as a waiver of any other right at any other time.

             Borrower agrees to pay all out-of-pocket expenses, including, but
not limited to, reasonable attorneys' fees, court costs, storage costs, rental
charges, transportation charges and similar expenses paid or incurred in
enforcing any of Lender's rights hereunder or in connection with any of the
collateral securing this Note, promptly on demand of Lender or other person
incurring the same.

             Lender may at any time transfer this Note and Lender's rights in
any collateral securing this Note, and Lender thereafter shall be relieved from
all liability with respect to such collateral for any damage occurring after
such transfer.

             This Note shall be governed and construed in accordance with the
internal laws of the State of Illinois and shall be binding upon Borrower and
their respective legal representatives, successors and assigns. If this Note
contains any blanks when executed by Borrower, Lender is hereby authorized,
without notice to Borrower, to complete any such blanks according to the terms
upon which the loan is granted. Wherever possible, each provision of this Note
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Note shall be prohibited by or
invalid under such law, such provision shall be severable, and be ineffective to
the extent of such prohibition or invalidity, without invalidating the remaining
provisions of this Note.

             TO INDUCE LENDER TO ACCEPT THIS NOTE, BORROWER IRREVOCABLY AGREES
THAT, SUBJECT TO LENDER'S SOLE AND ABSOLUTE ELECTION, ALL ACTIONS OR PROCEEDINGS
IN ANY WAY, MANNER OR RESPECT, ARISING OUT OF OR FROM OR RELATED TO THIS NOTE,
SHALL BE LITIGATED IN COURTS HAVING SITES WITHIN THE COUNTY OF COOK, STATE OF
ILLINOIS. BORROWER HEREBY

CONCERNING ANY MATTER RELATING TO THIS NOTE, THE LOAN AGREEMENT, THE ANCILLARY
DOCUMENTS AND ANY SECURITY DOCUMENT, AND (II) ANY RIGHTS BORROWER MAY HAVE TO
TRANSFER OR CHANGE THE VENUE OF ANY LITIGATION BROUGHT AGAINST BORROWER BY
LENDER IN ACCORDANCE WITH THIS PARAGRAPH.

$1,500,000                                                        March 26, 1997
Chicago, Illinois

             Sabratek Corporation, a Delaware corporation ("Borrower"), FOR
VALUE RECEIVED, unconditionally promises to pay to the order of LaSalle Bank NI
("Lender"), at 3201 North Ashland Avenue, Chicago, Illinois 60657, or at such
other place as the holder of this Equipment Term Note may designate in writing,
the principal sum owed by Borrower to Lender pursuant to the Equipment Term Loan
evidenced by this Note. Such Equipment Term Loan is part of the Equipment
Purchase Facility referenced in Section 2.1.3 of that certain Credit Agreement
dated March 26, 1997 (as the same may at any time be amended or modified and in
effect, the "Loan Agreement"), between Borrower and Lender. The Equipment Term
Loan evidenced by this Note shall be repaid in full not later than [April 30,
2004].

             Borrower promises to pay interest on the outstanding principal
amount hereunder until paid, pursuant to the terms of the Loan Agreement and at
the rates per annum and on the dates specified in the Loan Agreement. The
principal amount due hereunder shall be repaid as set forth in the Loan
Agreement. Payments of principal and interest hereunder are to be made in lawful
money of the United States of America and in immediately available funds.

             Capitalized terms used in this Note that are not specifically 
defined herein but are defined in the Loan Agreement shall have the meanings in
this    Note given to them in the Loan Agreement. Lender is authorized to
record, on a schedule annexed hereto, or on other appropriate records of
Lender, the date, type and amount of each Equipment Term Loan under the
Equipment Purchase Facility, any continuation thereof, any conversion of all or
a portion thereof to a different type of Equipment Term Loan, and the date and
amount of each payment or prepayment of principal thereof, and any such
recordation shall constitute prima facie evidence of the accuracy of the
information so recorded; provided that the failure of lender to make such
recordation (or any error in such recordation) shall not affect the obligations
of Borrower hereunder or under the Loan Agreement in respect of such Equipment
Term Loans.

             This Note is the note described in Section 2.1.3.3 of the Loan
Agreement, and is subject to the terms and provisions of the Loan Agreement.
Reference is hereby made to the Loan Agreement for a statement of the terms and
conditions under which the Equipment Term Loan was made and is to be repaid,
including prepayment rights and obligations of Borrower, nature, extent and
rights in any collateral security, and a statement of the terms and conditions
under which the due date of this Note may be accelerated.

             Borrower hereby waives presentment, demand, protest and notice of
presentment, demand, nonpayment and protest. Any failure of Lender to exercise
any right available hereunder or otherwise shall not be construed as a waiver of
the right to exercise the same or as a waiver of any other right at any other
time.

                                   Schedule I
                 to Credit Agreement Dated as of March 26, 1997

1.           Litigation:

             (a)         On February 5, 1997, SIMS Deltec filed a complaint in
                         the U.S. District Court for the District of Minnesota
                         (Sims Deltec, Inc. vs. Sabratek Corporation) alleging
                         that Borrower's manufacture, use and/or sale of the
                         MediVIEW software in conjunction with its infusion
                         pumps infringes a patent previously issued to SIMS
                         Deltec. The Borrower is being represented by Fitch,
                         Even, Tabin & Flannery of Chicago.

             (b)         The Borrower is a party to a lawsuit filed by a former
                         employee (Garrison v. Sabratek Corporation) seeking
                         payment of certain compensation. The Borrower is being
                         represented by Jenner & Block.

2.           Indebtedness:

             (a)         In connection with a training program, the Borrower is
                         indebted to the State of Illinois in the approximate
                         amount of $4,000.

             (b)         The Borrower is a party to a number of conditional sale
                         agreements providing for the lease of certain fixed
                         assets, computer hardware, office and production
                         equipment. The lessors are: Acclaim Leasing (Advanta),
                         Comdisco and Funding Services, Inc. (assigned to GE
                         Capital). Attached hereto as Attachment A is a list of
                         each such lease.

             (c)         The Borrower formerly financed receivables with
                         Sterling Business Credit, a division of Standard
                         Factors Corp. Although Borrower's financing with
                         Sterling has been terminated, and Sterling has
                         delivered copies of U.C.C.-3 termination statements
                         terminating Sterling's interest in Borrower's assets,
                         Sterling's Forms U.C.C.-3 have apparently not been
                         filed and Sterling's security interests continue to
                         appear of record.
