                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by, and should be read
in conjunction with, the more detailed information and financial data, including
the Financial Statements and Notes thereto, appearing elsewhere in this
Prospectus. Unless otherwise indicated, all information contained in this
Prospectus (i) assumes that the Underwriters' over-allotment option is not
exercised, (ii) assumes the exercise of outstanding options and warrants to
purchase 213,776 shares of Common Stock by the Selling Stockholders and receipt
by the Company of $1,035,517 in proceeds in connection therewith and (iii) has
been adjusted to give effect to a 1-for-3.173 reverse stock split which was
effected by the Company in connection with its initial public offering of
2,875,000 shares of Common Stock in June, 1996. See "Underwriting" and "Selling
Stockholders." This Prospectus contains certain forward-looking statements
within the meaning of the Federal securities laws. Actual results and the timing
of certain events could differ materially from those projected in the
forward-looking statements due to a number of factors, including those set forth
under "Risk Factors" and elsewhere in this Prospectus.
 
                                  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 several additional products which
it believes will contribute to future revenues.
 
     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 rendered 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
                                        3

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 the Food and Drug Administration (the "FDA"). In 1996, the
Company began marketing its proprietary medical software system ("MediVIEW") and
its proprietary infusion pump testing device (the "PumpMaster"). The Company
currently markets its products domestically to national, regional and local
alternate-site and acute-care providers through a sales force composed of 17
direct sales professionals, six clinical support staff and two full-time sales
consultants combined 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.
 
     The Company's goal is 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) develop advanced medical products and
related software systems that maximize the cost-effective provision of
alternate-site health care, (ii) develop an integrated system of therapeutic and
diagnostic information-based medical products supported by the Company's
proprietary health care information system platform, and (iii) create a
proprietary outcomes database through the Company's products and software system
platform.
 
                              RECENT DEVELOPMENTS
 
     On February 25, 1997, Sabratek acquired substantially all the assets of
Rocap, Inc. ("Rocap") for $100,000 in cash, 131,593 shares of Sabratek Common
Stock (valued at approximately $2.9 million), plus the assumption of net
liabilities of approximately $661,000 and the forgiveness of a bridge loan. In
connection with the acquisition, the former President of Rocap entered into a
three-year employment agreement with Sabratek.
 
     Rocap produces and markets prepackaged injectable prescription
pharmaceuticals (intravenous or "I.V." Admixture products) and pre-filled I.V.
tubing flush syringes for the alternative-site and acute-care markets. The
Company believes the addition of the Rocap product line expands the scope of the
Company's I.V. delivery systems, products, and services, thereby enhancing the
Company's competitive position.

                                  RISK FACTORS
 
     This Prospectus contains certain forward-looking statements within the
meaning of the Federal securities laws. Actual results and the timing of certain
events could differ materially from those projected in the forward-looking
statements due to a number of factors, including those set forth below and
elsewhere in this Prospectus. In addition to the other information contained in
this Prospectus, prospective investors should carefully consider the risk
factors set forth below in evaluating an investment in the shares of Common
Stock offered hereby.
 
HISTORY OF LOSSES
 
     The Company was formed in 1989, introduced its first product in 1992, and
has incurred operating and net losses since its inception through September 30,
1996. The Company incurred net losses of approximately $3.6 million, $6.0
million, and $858,000 for the years 1994, 1995 and 1996, respectively, and as of
December 31, 1996, had an accumulated deficit of $14.3 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 for the last two calendar
quarters, 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. See "Selected Financial Data" and "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
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 recent
acquisition of Rocap reduce the Company's reliance on its principal product
line, 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. See "Business -- Products," "-- Sales and Marketing"
and "-- Competition."

<PAGE>   12
 
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, Advanced Medical, Inc., Baxter
International Inc. 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. See "Business -- Research and Development" and "-- Competition."
 
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 (the "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 for
Communicating with Ambulatory Medical Devices Such as Drug Delivery Devices"
previously issued to SIMS Deltec. The Complaint seeks injunctive relief,
unspecified monetary damages and costs. The Company has not yet formally
responded to the Complaint but intends to vigorously defend against the
allegations contained in the Complaint. 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.
 
LIMITED SALES AND MARKETING EXPERIENCE
 
     The Company has only begun to significantly expand its sales, marketing and
distribution force within the past year. 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,
 
                                        8
<PAGE>   13
 
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. See "Business -- Sales and Marketing."
 
BROAD DISCRETION WITH RESPECT TO ALLOCATION OF NET PROCEEDS
 
     The Company intends to use the net proceeds of the Offering for working
capital and general corporate purposes, including: expanding manufacturing
capacity; funding further product development efforts; and expanding sales and
marketing activities. In addition, proceeds may be used for future joint
ventures or acquisitions of technologies, products or companies complementary to
the Company's business. The Company has not yet identified the specific uses for
such net proceeds and will, therefore, retain broad discretion as to their
allocation. Pending such uses, the Company intends to invest the net proceeds in
short-term interest-bearing, investment-grade securities. See "Use of Proceeds."
 
RISKS ASSOCIATED WITH PAST AND FUTURE ACQUISITIONS
 
     In February, 1997, the Company acquired Rocap. Although the Company has no
pending agreements or commitments, the Company may make additional acquisitions
of complementary businesses, products or technologies in the future.
Acquisitions of companies, divisions of companies, or products entail numerous
risks, including (i) the potential inability to successfully integrate acquired
operations and products or to realize anticipated synergies, economies of scale
or other value, (ii) diversion of management's attention, and (iii) loss of key
employees of acquired operations. No assurance can be given that the Company
will not incur problems in integrating the Rocap operations or any future
acquisition and there can be no assurance that the acquisition of Rocap or any
future acquisition will increase the Company's profitability. Furthermore, there
can be no assurance that the Company will realize value from any such
acquisition which equals or exceeds the consideration paid. Any such problems
could have a material adverse effect on the Company's business, financial
condition and results of operations. In addition, future acquisitions by the
Company may result in dilutive issuances of equity securities, the incurrence of
additional debt, large one-time write-offs and the creation of goodwill or other
intangible assets that could result in amortization expense. These factors could
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Certain Transactions."
 
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.
See "Business -- Assembly and Manufacturing."
 
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. See "Business -- Assembly and
Manufacturing."
 
                                        9
<PAGE>   14
 
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. See
"Business -- Reimbursement."
 
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 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"). 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 registered with the FDA as a drug
manufacturer and repackager and its products are required to be manufactured
according to current good manufacturing practices. Some of the products
manufactured by the Rocap division have been listed with the FDA in accordance
with the Drug Listing Act of 1972. Some of the products manufactured by the
Rocap division contain drugs which are purchased from other manufacturers which
have received FDA approvals. There can be no assurance that the suppliers of
such drugs will be able to maintain such approvals. While Rocap currently
manufactures and distributes its products without any FDA approvals, there can
be no assurance that the FDA will allow the Rocap division to manufacture and
distribute new or altered products without obtaining FDA approvals. If in the
future the FDA concludes that the products manufactured and distributed by the
Company's Rocap division require that the products be relabeled, require Rocap
to obtain 510(k) clearance, require new drug approval, or other regulatory
approval, the FDA could prohibit the Rocap division from manufacturing and/or
distributing these products until the Company made the necessary submissions and
obtained any required approvals. The FDA could also take regulatory action
against the Company for the Rocap division's manufacture and/or distribution of
products. If the FDA were to take any of the foregoing actions with respect to
the Company, it could have a material adverse effect on the Company's
operations.
 
     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. 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 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
 
                                       10
<PAGE>   15
 
determine that the PumpMaster is a medical device that requires a 510(k)
Submission prior to its commercial 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 is currently in
the process of revising the regulatory requirements and review criteria for
software-related medical devices, which 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 85% complete. The
FDA reported this recall in the January 15, 1997, issue of the FDA Enforcement
Report. There can be no assurance that the FDA will not take further enforcement
action against the Company with respect to this matter.
 
     The Company is also subject to strict domestic and foreign regulations 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
good manufacturing practice ("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 may have
a material adverse effect on the Company's business, financial condition or
results of operations. See "Business -- Government Regulation."
 
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 $5.0 million per occurrence with an
annual aggregate policy limit of $5.0 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. See "Business -- Product
Liability Insurance."
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
     During the year ended December 31, 1996, the Company derived approximately
9% 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, 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. See "Business -- Sales and Marketing" and "-- Intellectual
Property."

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. See
"Selected Financial Data" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
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. See "Business --
Employees."
 
NEED FOR ADDITIONAL FINANCING
 
     The Company anticipates that the net proceeds of the Offering will be
adequate to satisfy its operating and capital requirements at least through the
end of 1998. However, changes in the Company's business or business plan could
affect the Company's capital requirements. The Company's future capital
requirements will depend on many factors, including, but not limited to, the
cost of manufacturing and marketing activities, its ability to successfully
market its products, the scope of its research and development programs, the
length of time required to collect accounts receivable, competing technological
and market developments, and potential acquisitions. If additional financing is
needed, beyond the amount available under existing credit facilities, there can
be no assurance that it will be available on terms acceptable to the Company, if
at all, or that such financing would not be dilutive to existing stockholders.
See "Use of Proceeds" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
INFLUENCE OF LIMITED NUMBER OF STOCKHOLDERS
 
     Following completion of the Offering, 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. See "Principal
Stockholders."
 
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
 
                                       12
<PAGE>   17
 
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. See "Underwriting."
 
ADVERSE IMPACT OF SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of shares of Common Stock (including shares issued upon the exercise
of outstanding options or warrants) in the public market after the Offering or
the perception that such sales could occur could adversely affect the market
price of the Common Stock. Such sales also might make it more difficult for the
Company to sell equity securities or equity-related securities in the future at
a time and price that the Company deems appropriate. Upon completion of the
Offering, the Company will have approximately 10,288,005 shares of Common Stock
outstanding. The 2,232,028 shares offered hereby and the 2,875,000 shares issued
by the Company in its initial public offering in June 1996 will be freely
tradable without restriction, unless purchased by an affiliate of the Company.
Of the remaining 5,180,977 shares outstanding, approximately 2,058,840 shares
will be available for sale upon the effective date of the Registration Statement
of which this Prospectus is a part (the "Effective Date") pursuant to Rule 144
promulgated under the Securities Act of 1933, as amended (the "Act"). Shares
held by the Selling Stockholders (other than those sold in the Offering), all
directors, certain officers, and certain stockholders are subject to lock-ups of
60 or 90 days and may become available for sale upon the expiration of such
lock-ups. Bear, Stearns & Co. Inc. may waive the foregoing lock-up without
notice to persons purchasing shares in this Offering and without notice to any
market on which the Common Stock is traded. In addition, certain holders of the
Company's Common Stock have registration rights. See "Shares Eligible for Future
Sale", "Dilution." "Description of Capital Stock -- Registration Rights" and
"Shares Eligible for Future Sale."
 
IMPACT OF ANTI-TAKEOVER MEASURES; POSSIBLE ISSUANCE OF PREFERRED STOCK;
CLASSIFIED BOARD
 
     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.
 
     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.
 
SUBSTANTIAL DILUTION AND ABSENCE OF DIVIDENDS
 
     Purchasers of shares of Common Stock in the Offering will experience
immediate and substantial dilution in the net tangible book value per share of
Common Stock from the public offering price. In addition, the exercise of
outstanding options and warrants will result in further dilution. See
"Dilution." The Company has never paid any cash dividends and does not
anticipate paying cash dividends on its Common Stock in the foreseeable future.
See "Dividend Policy."

                                  THE COMPANY
 
     The Company was organized under Illinois law in December, 1989, and was
reincorporated under Delaware law in December, 1991. The Company's executive
offices are located at 5601 West Howard Street, Niles, Illinois 60714. The
Company's telephone number is (847) 647-2760.
 
                                USE OF PROCEEDS
 
     The net proceeds to be received by the Company from the sale of the
1,700,000 shares of Common Stock offered by it pursuant hereto are estimated to
be approximately $39.3 million ($47.1 million if the Underwriters'
over-allotment option is exercised in full), at an assumed public offering price
of $24.75 per share, after deducting underwriting discounts and commissions and
estimated offering expenses. The Company will not receive any proceeds from the
sale of the 532,028 shares of Common Stock offered by the Selling Stockholders
pursuant hereto. The Company will, however, receive proceeds of approximately
$1,035,517 upon exercise of outstanding options and warrants to purchase 213,776
shares of Common Stock by Selling Stockholders.
 
     The Company estimates that it will use the net proceeds in the following
manner: 20% for expanding manufacturing capacity; 20% for financing further
product development efforts; and 15% for expanding sales and marketing
activities, with the remainder to be used for working capital and general
corporate purposes. In addition, proceeds may be used for future joint ventures
or acquisitions of technologies, products or companies which are complementary
to the Company's business.
 
                          PRICE RANGE OF COMMON STOCK
 
     The Company completed its initial public offering in June, 1996 at a price
per share of $10.00. Since June 21, 1996, the Company's Common Stock has traded
on the Nasdaq National Market under the symbol "SBTK". The following table sets
forth, for the periods indicated, the high and low reported sale prices of
shares of the Common Stock as reported on the Nasdaq National Market.

     As of March 7, 1997, there were approximately 214 holders of record of the
Common Stock. On March 14, 1997, the last reported sale price on the Nasdaq
National Market for the Common Stock was $24.75 per share.
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid any cash dividends on its capital
stock. The Company currently intends to retain all available funds for use in
its business and therefore does not intend to pay any cash dividends on its
Common Stock in the foreseeable future.

                                    DILUTION
 
     The net tangible book value of the Company as of December 31, 1996 was
$28,608,542, or $3.49 per share. Net tangible book value per share is determined
by dividing the tangible net worth of the Company (total tangible assets less
total liabilities) by the number of shares of Common Stock outstanding. Without
taking into account any changes in such net tangible book value after December
31, 1996, other than to give effect to the sale of the 1,700,000 shares of
Common Stock offered by the Company hereby at an assumed public offering price
of $24.75 per share and receipt by the Company of $1,035,517 upon the exercise
of outstanding options and warrants to purchase 213,776 shares of Common Stock
by the Selling Stockholders, net tangible book value of the Company as of
December 31, 1996 would have been $68,904,934, or $6.82 per share (after
deducting the estimated underwriting discount and offering expenses payable by
the Company). This represents an immediate increase in net tangible book value
of $3.33 per share to existing stockholders and an immediate dilution of $17.93
per share to new investors. Dilution to new investors is determined by
subtracting the net tangible book value per share after the Offering from the
public offering price per share. The following table illustrates this per share
dilution.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
     Since its inception in 1989, through 1991, the Company was in its
development stage and engaged primarily in research and development, product
engineering and activities related to obtaining clearance from the FDA for its
first product, the 3030 Stationary Pump. The Company has a limited operating
history and, although profitable for the last two calendar quarters, has
experienced significant operating losses since inception. Upon receiving FDA
clearance for the 3030 Stationary Pump in mid-1992, the Company focused its
efforts on creating a domestic and international sales and marketing network, as
well as a manufacturing capability, to assist in the distribution of its first
product to the alternate-site health care market. Concurrent with these sales
and marketing activities, the Company continued to fund the research,
development and regulatory clearance activities of other device and software
products. See "Risk Factors -- History of Losses."
 
     The Company commercially launched the 6060 Ambulatory Pump and related
disposable supplies in late 1995 and its MediVIEW and PumpMaster in late 1996.
Since then, the Company has continued its sales and marketing activities
domestically and internationally for the distribution of its products and
continued to fund the research and development of additional products. In
addition, the Company derives revenues from the rental of its multi-therapy
infusion devices, servicing of products, and the sale of extended warranties.
See "Risk Factors -- Dependence on Principal Product Line and New Product
Development."
 
     The Company sells its products both directly to alternate-site and
acute-care providers, as well as to third-party distributors. The Company's
distributors and customers may purchase several months of inventory at any one
time which may cause fluctuations in quarterly revenues. Quarterly fluctuations
may also result from other factors. The Company also markets and sells its
products internationally and, as a result, its revenues may be affected by
fluctuations in exchange rates. Failure to obtain regulatory approval for the
distribution of new products domestically or in international markets, or
regulatory problems in general, may affect the revenues of the Company. See
"Risk Factors -- Dependence on Principal Product Line and New Product
Development," "-- Governmental Regulations," "-- International Operations," and
"-- Quarterly Fluctuations."
 
RESULTS OF OPERATIONS
 
YEARS ENDED DECEMBER 31, 1996 AND 1995
 
     NET SALES. Net sales increased to $17.7 million for the year ended December
31, 1996 from $4.0 million for the year ended December 31, 1995, an increase of
$13.7 million or 343%. The increase is primarily attributable to an increase in
sales volume of the 3030 Stationary Pump, the 6060 Ambulatory Pump and the
respective disposables, to the alternate-site health care market. Also
contributing to the increase was the introduction of the MediVIEW and PumpMaster
products.
 
     COST OF SALES. Cost of sales increased to $8.7 million for the year ended
December 31, 1996 from $2.9 million for the year ended December 31, 1995, an
increase of $5.8 million, or 200%. Approximately $5.3 million of the increase
represents the direct manufacturing cost attributable to the increase in sales
volume and the balance of the increase is attributable to the investment in
fixed manufacturing costs and overhead necessary to increase production
capacity.
 
     GROSS MARGIN. Gross margin increased to $8.9 million for the year ended
December 31, 1996 from $1.1 million for the year ended December 31, 1995, an
increase of $7.8 million, or 709%. The increase is due primarily to the increase
in sales volume and the resulting economies of scale associated with the
increase. Gross margin as a percentage of sales increased to 50% for the year
ended December 31, 1996, from 28% for the year ended December 31, 1995. The
increase is due to the absorption of fixed manufacturing costs and overhead over
a greater unit volume, higher average pricing levels for the 3030 Stationary
Pump, and the higher margins inherent to the 6060 Ambulatory Pump introduced in
the fourth quarter of 1995.
 
                                       18
<PAGE>   23
 
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased to $8.5 million for the year ended December
31, 1996 from $6.9 million for the year ended December 31, 1995, an increase of
$1.6 million, or 23%. Expansion of the Company's sales and clinical support
staff increased selling, general and administrative expenses by approximately
$1.8 million while reductions and elimination of financial, marketing and
product development consulting fees represent the offsetting amount. Selling,
general and administrative expenses as a percent of sales decreased to 48% for
the year ended December 31, 1996 from 173% for the year ended December 31, 1995.
The decrease is due to the allocation of overhead expenses over a greater volume
of sales.
 
     OPERATING INCOME (LOSS). The Company reported operating income of $474,000
for the year ended December 31, 1996 as compared to an operating loss of $5.7
million for the year ended December 31, 1995. The primary contributors to
operating profitability, as discussed above, are the incremental sales volume of
the 3030 Stationary Pump and the 6060 Ambulatory Pump and related products.
 
     INTEREST EXPENSE. Interest expense increased to $319,000 for the year ended
December 31, 1996 from $222,000 for the year ended December 31, 1995, an
increase of $97,000, or 44%. The increase is attributable to the incremental
amount of debt issued by the Company and outstanding during the comparative
periods. Approximately $1.8 million, in aggregate, of debt was issued between
July and December, 1995 and was outstanding through the end of June, 1996.
 
     INTEREST INCOME. Interest income increased to $617,000 for the year ended
December 31, 1996 from $13,000 for the year ended December 31, 1995. The
increase of $604,000 is due to the investment interest earned on proceeds from
the Company's initial public offering in June, 1996.
 
     INCOME TAX PROVISION. Due to net losses for the years ended December 31,
1996 and 1995, the Company did not incur any federal or state income tax
liability for such periods. The Company currently has a net operating loss
carryforward in excess of $14.0 million; however, utilization of such
carryforward depends on future earnings and will be subject to annual
limitations as a result of changes that have occurred in the Company's
ownership.
 
     NET LOSS. Net loss decreased to $858,000 for the year ended December 31,
1996 from $6.0 million for the year ended December 31, 1995, a decrease of $5.1
million. The loss was reduced primarily as a result of increased sales volume of
new and existing products, as discussed above, and the allocation of fixed
manufacturing cost and overhead over a greater unit volume. The year ended
December 31, 1996 includes a non-recurring charge for stock appreciation rights
of approximately $1.6 million in connection with the Company's June, 1996
initial public offering, without which the Company would have reported net
income of $770,000.
 
YEARS ENDED DECEMBER 31, 1995 AND 1994
 
     NET SALES. Net sales increased to $4.0 million for the year ended December
31, 1995 from $3.3 million for the year ended December 31, 1994, an increase of
$725,000 or 22%. The market launch of the 6060 Ambulatory Pump and related
disposable tubing sets in the fourth quarter of 1995 accounted for approximately
$611,000 of the increase. The remaining amount was attributable to further
penetration of the alternate-site health care market through sales of the 3030
Stationary Pump and related disposable tubing sets by regional distributors, the
implementation of a direct sales and marketing program in non-distributor
territories and the signing of additional national accounts.
 
     COST OF SALES. Cost of sales increased to $2.9 million for the year ended
December 31, 1995 from $2.5 million for the year ended December 31, 1994, an
increase of $421,000, or 17%. Approximately $399,000 of the increase was
attributed to increased sales volume. The remainder was related to the expansion
of the Company's manufacturing capacities, including an increase in operations
headcount and facility. Cost of sales as a percentage of sales decreased to 72%
in 1995 from 75% in 1994 as a result of the change in product mix, as well as
efficiencies from volume purchases of supplies. However, the overall decrease in
cost of sales from these factors was partially offset by the costs associated
with increases in manufacturing capacities.
 
                                       19
<PAGE>   24
 
     GROSS MARGIN. Gross margin increased to $1.1 million for the year ended
December 31, 1995 from $834,000 for the year ended December 31, 1994, an
increase of $304,000, or 36%. This increase in gross margin was attributable to
the higher percentage of sales to national accounts during 1995 at pricing
levels which were typically higher than those of sales to the Company's
distributors.
 
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased to $6.9 million for the year ended December
31, 1995 from $4.1 million for the year ended December 31, 1994, an increase of
$2.8 million, or 68%. Selling, general and administrative expenses accounted for
170% of net sales in 1995 and 124% of net sales in 1994. The high level of such
expenses in both 1994 and 1995 is attributable to the Company's development of
its sales and marketing organization, expansion of its administrative staff, and
efforts to obtain FDA clearance for its products. The increase in such expenses
in 1995 from 1994 resulted primarily from an increase in the number of direct
sales personnel, increased expenditures relating to development of the 6060
Ambulatory Pump, MediVIEW and PumpMaster, the creation of a clinical support
department, and the further addition of administrative support staff.
Additionally, financial advisory fees of $410,000 were recorded in 1995.
 
     OPERATING LOSS. Operating loss increased to $5.7 million for the year ended
December 31, 1995 from $3.3 million for the year ended December 31, 1994.
 
     INTEREST EXPENSE. Interest expense decreased to $222,000 for the year ended
December 31, 1995 from $260,000 for the year ended December 31, 1994. This
decrease was primarily attributable to a reduction of average debt outstanding
during the year.
 
     INCOME TAX PROVISION. The Company had net operating losses for the years
ended December 31, 1995 and 1994, and therefore did not incur any federal or
state income tax liability.
 
     NET LOSS. As a result of the items discussed above, the Company's net loss
increased to $6.0 million for the year ended December 31, 1995 from $3.6 million
for the year ended December 31, 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     In June, 1996, the Company completed an initial public offering with
proceeds of $26.7 million, after underwriters' discounts and commissions. As of
December 31, 1996, cash balances were invested in U.S. Treasury Bills, U.S.
Treasury Notes, a short-term bond mutual fund, and a money market account.
 
     As of December 31, 1996, the Company had approximately $16.8 million in
cash, cash equivalents, short-term and long-term investments in marketable
securities, and had net working capital of approximately $24.6 million.
Subsequent to December 31, 1996, the Company received a commitment for a credit
facility with up to $9.5 million of available borrowing.
 
     The Company used cash in its operations of approximately $8.4 million for
the year ended December 31, 1996. Cash used in operations for the period exceeds
the Company's operating results for the same period due, primarily, to the
growth in trade accounts receivable and inventories as a result of actual and
anticipated growth in sales volume.
 
     The Company believes that its financial assets will be sufficient to fund
its operations for the foreseeable future. Future liquidity and capital
resources could be adversely influenced by certain factors including the
Company's dependence on a relatively new customer base, regulatory or
legislative changes pertaining to health care, product liability exposure
regarding the delivery of medication, dependence on future product development,
and others. There can be no assurance that the Company will not require
additional financing and may, in the future, seek additional funds through bank
facilities, debt or equity offerings and to the extent such additional financing
is not available, the Company could suffer material adverse effects to its
financial condition and the results of its operations.

INTRODUCTION
 
     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 several additional products which it believes will
contribute to future revenues.
 
CHANGING HEALTH CARE ENVIRONMENT
 
     The increase in health care costs at a rate significantly higher than that
of overall inflation has caused managed care companies, indemnity insurers,
employers, governmental agencies and other payors to employ a variety of
strategies designed to contain health care expenditures. These cost-containment
strategies aim to reduce the price paid for health care services, as well as the
amount of health care services utilized. In certain markets, payors are shifting
away from traditional fee-for-service based payment plans and moving towards
managed care plans in an effort to deliver quality health care services more
cost-effectively. In particular, cost-containment measures, including increased
utilization review and case management, have caused many health care providers
to move patients from the higher-cost hospital setting to lower-cost alternate
sites.
 
     The alternate-site health care industry, which includes the delivery of
skilled nursing services, intravenous infusion, respiratory therapy, physical
therapy and pharmaceutical therapies in the home, long-term care facilities,
physicians' offices and outpatient centers, has grown significantly during the
past decade. According to a report entitled "National Health Expenditure
Projections, 1994-2005" published in the summer of 1995 by HCFA, total
expenditures for home health care, which constitutes a significant component of
alternate-site health care, increased from approximately $11.1 billion in 1990
to approximately $24.2 billion in 1994 and is projected to reach $45.9 billion
in 2000. Since the early 1980s, the provision of acute and chronic care for
serious illnesses outside the hospital has been recognized as a critical
component of health care cost containment because the delivery of certain
therapies in an alternate-site setting is more cost effective than the delivery
of these same therapies in an acute-care hospital setting. The Company believes
that the alternate-site health care industry will continue to benefit from
cost-containment measures which governmental and private payors have employed to
reduce hospital admissions and lengths of stays in hospitals. The Company
believes that such measures will continue the increase in the use of
alternate-site health care due to its significantly lower cost when compared to
similar care provided in traditional health care settings. In addition to cost
savings, the alternate-site health care industry should continue to benefit from
advances in medical technology which have facilitated the provision of
sophisticated care outside the hospital. Many disease states, including
pulmonary diseases, neurological conditions, infectious diseases, digestive
disorders, AIDS-related symptoms, various forms of cancer and related medical
conditions such as pain and nausea, are now being treated in alternate-site
settings, including the home. Growth in alternate-site health care has also been
facilitated by the increased acceptance of such care by physicians, caregivers
and patients. The American Medical Association Council on Scientific Affairs and
the American Medical Association Council on Medical
 
                                       21
<PAGE>   26
 
Education have recommended that training in the principles and practice of home
health care be incorporated into the undergraduate, graduate and continuing
education of physicians. Also contributing to the growth of the alternate-site
health care industry is the increase in the over-65 population, which has a
higher incidence of illness and disability.
 
     A significant component of alternate-site health care is infusion therapy,
which involves the administration of fluid intravenously at a regulated rate and
volume. Alternate-site infusion therapy has historically been the
fastest-growing segment of the alternate-site health care market. According to
POV, Incorporated, an industry tracking and consulting firm, the infusion
therapy segment of this market is expected to grow in revenues from $3.2 billion
in 1992 to $7.9 billion in 1997, representing an average annual compounded
growth rate of approximately 20%. Infusion therapy is used in a wide range of
applications such as nutrition therapy, pain management, delivery of
antibiotics, pregnancy and obstetrical therapies, chemotherapy, cardiovascular
therapy and immunosuppressive therapy. These therapies generally require the use
of specialized infusion pumps to deliver precise dosages of fluids such as
nutrients, parenteral solutions, anti-infectives, chemotherapeutic agents,
narcotic analgesics and a variety of other drugs.
 
     Due to the shift by managed care payors toward fixed fee or capitated
payment arrangements, providers of infusion therapy are being forced to reduce
costs without compromising the quality of care in order to maintain
profitability. The costs associated with providing infusion therapy are composed
of three general components: capital equipment, supplies and labor.
Traditionally, providers of infusion therapy needed to purchase multiple types
of infusion pumps and related back-up inventory because most pumps delivered
only one type of therapy. This requirement to purchase several single therapy
pumps also results in increased labor training costs because of the need to
learn multiple programming protocols. The delivery of infusion therapy requires
a substantial amount of non-clinical nursing time. The Company believes that
reducing the labor costs of delivering infusion therapy is critical for
alternate-site health care providers to achieve operating efficiencies.
According to a 1992 study of the home infusion therapy industry published by The
National Alliance for Infusion Therapy (the "NAIT Study"), nurses spent an
average of 3.1 hours per home visit, of which approximately 64 minutes, or 35%,
was spent traveling to and from the patient's home, 56 minutes, or 30%, was
spent documenting clinical observations as well as coordinating care and the
balance was spent on tasks performed during personal contact with the patient,
including documentation. The NAIT Study also shows that training is required for
patients not only at the start of therapy but also over time as the therapy of
an individual patient changes. The NAIT Study indicates that during such home
visits, a significant amount of nursing time is required to ensure that patients
are complying with the prescribed therapy. Compliance is important to ensure
that patients are not required to re-enter the costly hospital setting thereby
generating unnecessary incremental expenses and health risks as a result of
failure to adhere to their prescribed therapies, whether intentionally or
unintentionally. The Company believes that products and technology which reduce
the cost of providing infusion therapy, especially the labor component, will be
attractive to health care payors in general and providers of infusion therapy in
particular.
 
BUSINESS STRATEGY
 
     The Company's goal is to become a leading developer and marketer of
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 pursuing the following business
strategies:
 
     - OFFER ADVANCED MEDICAL PRODUCTS AND RELATED SOFTWARE SYSTEMS THAT
      MAXIMIZE THE COST-EFFECTIVE PROVISION OF ALTERNATE-SITE HEALTH CARE. The
      Company has designed its multi-therapy infusion products and related
      software system, and intends to develop additional products, to address
      the various needs of its major constituencies -- payors, providers and
      patients and their families.
 
        Payors -- The Company believes that payors are primarily concerned with
        reducing costs while assuring the quality of health care. The Company's
        multi-therapy infusion system has the flexibility to effectively treat a
        wide range of disease states in the lower cost alternate-site market.
        Characteristics of the Company's infusion and software systems help
        address quality assurance concerns through such features as real-time
        data capture, remote monitoring capability, alarms that immediately
        alert
 
                                       22
<PAGE>   27
 
        providers of non-compliance and the capability to perform customized
        outcomes analysis. Such analyses also help provide oversight of the
        practice patterns of health care providers.
 
        Providers -- The Company believes that alternate-site providers are
        concerned with improving their ability to effectively treat patients
        through the use of products that reduce labor costs, allow real-time
        patient monitoring, improve patient compliance and provide data to
        develop better protocols in order to improve operating efficiencies.
        This is particularly true under capitated payment programs. The
        Company's infusion products incorporate user-friendly characteristics
        that minimize set-up time and nurse/patient training, and have the
        flexibility to provide multiple therapies using a single infusion
        device. Additionally, the Company believes that its infusion pumps'
        capabilities for remote interactive programming and monitoring on a
        real-time basis considerably reduce costly on-site nurse intervention.
        The ability of the Company's infusion system to administer a variety of
        infusion therapies, as well as the Company's infusion pump testing
        device, allow providers to minimize their inventories of infusion pumps
        and related supplies. The Company's infusion pump testing device can
        further reduce costs by eliminating outside recalibration and
        preventative maintenance costs. The Company believes that the advanced
        features incorporated in its infusion system allow providers to treat
        higher acuity patients in the alternate-site setting who could
        previously only be treated in an acute-care hospital. In combination
        with the Company's interactive software, Sabratek's infusion pumps will
        enable health care professionals to collect diagnostic and therapeutic
        data useful in the analysis and development of clinical protocols and
        provide insight into practice patterns, thereby reducing the need for
        frequent on-site visits and evaluations as well as redundant and
        burdensome record-keeping.
 
        Patients and their Families -- The Company believes that, while
        undergoing infusion therapy, patients and their families want comfort,
        peace of mind, ease of use and more control over their lives. The
        Company's infusion system meets these needs through such characteristics
        as user-friendly programming to aid those patients who are not
        technologically literate, multiple language formats, quietness of
        operation, bright LED displays, alarm system warnings of non-compliance
        and, when used in conjunction with the Company's interactive software,
        the ability to provide real-time information over standard telephone
        lines to providers in remote locations. Real-time monitoring and
        intervention capabilities provide patients with an increased comfort
        level to receive therapies in a home setting where they would otherwise
        feel uncomfortable because of the lack of immediately available medical
        personnel.
 
     - OFFER AN INTEGRATED SYSTEM OF THERAPEUTIC AND DIAGNOSTIC
      INFORMATION-BASED MEDICAL PRODUCTS SUPPORTED BY THE COMPANY'S PROPRIETARY
      HEALTH CARE INFORMATION SOFTWARE PLATFORM. The Company's software system
      allows health care providers to program and monitor the Company's infusion
      pumps and capture data for reporting and clinical purposes from a remote
      location on a real-time basis. The Company intends to expand the
      capabilities of its proprietary medical information software as well as
      its line of advanced, user-friendly medical devices to create a complete
      interactive system that addresses a variety of therapeutic and diagnostic
      applications in the alternate-site health care industry. The Company
      intends to expand its line of products through further internal product
      design and development, licensing arrangements, joint ventures and
      acquisitions of technology, products and companies when available.
 
     - CREATE A PROPRIETARY OUTCOMES DATABASE THROUGH THE COMPANY'S PRODUCTS AND
      SOFTWARE SYSTEM PLATFORM. The Company's strategy is to expand the
      installed base of its interactive medical system and to become the
      preferred vendor of such system to alternate-site health care providers.
      The Company believes that its software-based medical systems will serve as
      a platform on which to develop interactive communication and information
      systems designed to allow payors and providers to capture and analyze
      clinical data to design the most cost-effective therapy protocols and
      practice patterns. The Company has designed its proprietary information
      system to incorporate a wide range of real-time, remote programming,
      monitoring and administrative report functions for multiple therapeutic
      modalities beyond infusion therapy.

PRODUCTS
 
     SABRATEK'S SEAMLESS DELIVERY SYSTEM.  Sabratek's software-based infusion
devices and related interactive information system and pump testing device are
designed to provide both health care professionals and patients with ease of use
and a smooth transition throughout the health care delivery spectrum. Sabratek's
SEAMLESS DELIVERY SYSTEM product design is the Company's strategic response to
the need to achieve cost-effective movement of patients from a hospital setting
to an alternate-site setting, and among the various stages in alternate-site
care, from sub-acute to home care, with maximum ease of transition. The SEAMLESS
DELIVERY SYSTEM maximizes the similarities between Sabratek's stationary and
ambulatory infusion devices and is intended to allow both patients and health
care providers to use both types of infusion devices interchangeably, as the

     SABRATEK 3030 -- STATIONARY MULTI-THERAPY INFUSION PUMP.  The Company's
3030 Stationary Pump is an electromechanical, volumetric infusion device that is
able to deliver a wide variety of infusion therapies including, among others,
chemotherapy, antibiotics, circadian rhythms and total parenteral nutrition
under three standard and one customizable delivery modes. The 3030 Stationary
Pump incorporates multiple language capabilities, remote communications and
pre-programming capabilities, a state-of-the-art ergonomic design and a
relatively easy-to-learn programming format. The 3030 Stationary Pump operates
with leading brands of disposable tubing as well as Sabratek's own line of
non-proprietary disposable tubing.
 
     SABRATEK 6060/HOMERUN -- AMBULATORY MULTI-THERAPY INFUSION PUMP.  The
Company's 6060 Ambulatory Pump weighs approximately 13 ounces and can be worn
discreetly by a patient. The 6060 Ambulatory Pump was designed as a
complementary product to the 3030 Stationary Pump and, when combined with the
use of the 3030 Stationary Pump, provides a seamless transition between the bed
and an ambulatory state, or vice versa, with minimal additional training. The
6060 Ambulatory Pump has delivery capabilities and a programming format that are
similar to the 3030 Stationary Pump, with the addition of a pre-programmed
capability to deliver pain management infusion therapy. The 6060 Ambulatory Pump
also has the ability to work in conjunction with the MediVIEW software and
utilizes a proprietary disposable tubing set.
 
     DISPOSABLE INFUSION SUPPLIES.  The Company sells non-proprietary disposable
tubing sets for use with the 3030 Stationary Pump and proprietary disposable
tubing sets for use exclusively with the 6060 Ambulatory Pump. Through the
acquisition of Rocap, the Company has begun offering I.V. Admixture and
pre-filled syringe products.
 
     MEDIVIEW -- REMOTE PROGRAMMING, MONITORING AND DATA CAPTURE SOFTWARE
SYSTEM.  MediVIEW is a proprietary software system designed to allow providers
to program and monitor Sabratek's infusion pumps and capture data for reporting
and clinical purposes from remote locations over standard telephone lines. The
Company has designed MediVIEW to enable alternate-site health care providers
using the 3030 Stationary Pump and 6060 Ambulatory Pump combined with MediVIEW
to: (i) remotely monitor and program the Company's pumps on a real-time basis,
(ii) receive instantaneous notification of alarm activation and immediately
respond from the provider's physical location, (iii) automatically record and
"package" data regarding the outcomes of actual therapy courses for specific
case management and clinical as well as administrative/reimbursement purposes,
and (iv) develop a proprietary clinical protocol and outcomes database useful to
providers in managed care cases. In addition, patients who receive therapy on
the Company's infusion products should derive greater comfort because their
providers will be able to monitor their therapies on a real-time basis. The
first release of MediVIEW became commercially available in the third quarter of
1996.
 
     PUMPMASTER -- PORTABLE, AUTOMATIC DIAGNOSTIC DEVICE FOR THE TESTING OF
SABRATEK INFUSION PUMPS. The PumpMaster is a portable device designed to enable
providers to perform on-site diagnostic tests on Sabratek's infusion devices.
Pursuant to suggested standards adopted by the Joint Commission for the
Accreditation of Healthcare Organizations ("JCAHO"), an industry group which
promulgates standards relating to the provision of alternate-site health care,
the performance of every infusion pump is required to be re-certified on the
earlier of the date on which such pump is provided to a new patient for their
use or the date which is 12 months from the date of the last certification. The
Company believes that it is not cost-efficient for providers to maintain
in-house bio-medical engineering resources on a branch level to perform pump re-
certification. Instead, providers typically ship their pumps for remote-site
testing and, as a result, are required to maintain costly back-up pump
inventory. The PumpMaster is intended to obviate such incremental capital
expenditure outlays as well as eliminate the cost of outside infusion pump
testing. The PumpMaster is designed to conduct automatically, in approximately
ten minutes, all tests typically performed as part of JCAHO re-certification.
PumpMaster became commercially available in the fourth quarter of 1996.
 
SALES AND MARKETING
 
     The Company sells its products to a diverse group of customers in the
alternate-site health care industry such as sub-acute skilled nursing care
facilities, home health care providers, physicians' offices, clinics, surgery
 
                                       25
<PAGE>   30
 
centers and long-term care facilities. This group of customers ranges in size
from national and regional chains to local independent operators. The Company's
products are also sold to hospitals. Key decision makers include nursing,
pharmacy, purchasing and bio-medical departments, as well as physicians.
 
     As of December 31, 1996, the Company's domestic sales force consisted of 17
direct sales professionals, six clinical support staff and two full-time sales
consultants as well as a network of domestic distributors each of whom covers an
exclusive geographic territory. In certain limited geographic areas, the
distributors are directly involved in sales and implementation; in others, the
distributors act as support to the new client implementation process. The
Company's distributors have been selected for their experience in and focus on
the infusion therapy market, coverage of specific geographical areas, product
sales support and regional dominance. The Company's sales management team trains
the sales personnel of each of the distributors and provides them with all
product information and other relevant field literature. In addition, Sabratek's
direct sales representatives coordinate and manage national account activity.
The Company's marketing and sales efforts are supported by advertising in trade
journals, new product literature and attendance at trade shows. The Company
believes that its existing sales force and distribution network provide the
necessary infrastructure to market its current products and those under
development. The Company intends to use a portion of the proceeds from the
Offering to augment its sales and marketing staff and increase its marketing
efforts to further facilitate sales of current and future products.
 
     The Company has also entered into distribution agreements with distributors
in South America, Europe, the Middle East, Asia and Africa. For the year ended
December 31, 1996, international sales accounted for approximately 9% of the
Company's total sales. The Company perceives the international marketplace as a
potential area for future growth. The Company has distribution agreements in
Japan and Germany, which it believes are among the largest international markets
for infusion systems, and will commence marketing its products in these
countries upon receipt of regulatory approval. Currently, all of the Company's
international sales are invoiced and paid in U.S. dollars.
 
     The Company has enhanced its domestic sales effort through an affiliation
with Americorp Financial, Inc. ("Americorp") to provide leasing services to the
Company's domestic customers. Americorp has licensed the name "Sabratek Credit
Corporation" from the Company and offers financing for the acquisition of
Sabratek products under both capital and operating leases.
 
RESEARCH AND DEVELOPMENT
 
     The Company is committed to continued product innovation and has invested
approximately $1.0 million, $2.2 million and $1.1 million in research and
development for the years ended December 31, 1996, 1995 and 1994, respectively.
The Company's research and development effort is supported by a staff of twelve
electrical, mechanical and software engineers who have extensive experience in
the design and development of electromechanical infusion therapy devices, other
medical instrumentation and software. Sabratek's engineering team closely
coordinates its design activities with the Company's sales and marketing team.
This group solicits extensive pre-design focus group input from constituencies
that use or are impacted by the use of Sabratek's products, but who may possess
a host of different strategic, economic and other objectives.
 
     Sabratek's research and development program is focused on both new product
development and enhancements of existing products. The Company's product
development efforts include advancements in infusion therapy, interactive
software systems, vital signs monitoring, blood gas monitoring and whole blood
analysis. The Company's product development strategy is based on developing
product platforms that have the flexibility to be configured to respond to a
variety of customer requirements. The Company's product enhancement efforts are
based on the input received from customers after the initial introduction of its
products and focus on addressing customers' needs in a more cost-effective and
comprehensive way.
 
ASSEMBLY AND MANUFACTURING
 
     Sabratek currently assembles all of its infusion devices at its facility in
Niles, Illinois in an effort to ensure production quality and control its costs.
The Company outsources the manufacture of certain sub-systems used in its
infusion systems. In addition, disposable tubing sets sold by Sabratek are
manufactured by contract
 
                                       26
<PAGE>   31
 
manufacturers. Sabratek believes its use of in-house assembly and contract
manufacturing is the most cost-effective means of producing its products.
Additionally, Sabratek's Rocap division manufactures prepackaged injectible
prescription pharmaceuticals and pre-filled I.V. flush syringes at its facility
in Woburn, Massachusetts.
 
     The Company's production process for its infusion devices consists of
assembling major sub-systems as well as the assembly of both standard and custom
components. The standard components can be obtained from a number of sources.
The custom components are produced by both Sabratek as well as by sub-
contractors and, in all cases, competitive back-up supply sources exist. The
Company believes that, due to volume discounts, the unit cost of both standard
and custom components will decrease as production volumes increase.
 
     Disposable tubing sets are manufactured to Sabratek's specifications by
third parties in a clean room environment under stringent quality control
procedures covering assembly, storage and sterilization. Set production consists
of the assembly of both standard and custom components. The plastic custom
components are manufactured by a sub-contractor using molds supplied by the
Company. The Company uses more than one manufacturer for the production of its
disposable tubing sets.
 
QUALITY ASSURANCE
 
     The Company maintains a comprehensive quality assurance program. The
quality assurance program begins with the components and other materials the
Company purchases from vendors. Vendors are required to supply materials which
meet stated specifications. The Company monitors vendors' compliance with the
stated specifications through a program of on-site surveys, audits and product
testing. The Company also employs quality assurance procedures during its
on-site manufacturing and assembly process in an effort to ensure that finished
products meet the standards set by the Company. All finished products are tested
by the Company's separate quality assurance department to ensure that the
Company avoids distributing sub-standard products. Finally, the Company
maintains a post-sale performance monitoring program.
 
     Sabratek provides a one-year warranty on the 3030 Stationary Pump, the 6060
Ambulatory Pump and PumpMaster. This warranty is passed on to the end-users by
the distributors. To provide further product support, the Company has
established an in-house capability for repair, maintenance and upgrade of its
products. The repair and maintenance function utilizes full-time technical
personnel as well as on-going support from temporary and production personnel as
required to service infusion devices. The Company believes the service and
maintenance of its infusion devices require minimal manpower due to the
modularity of such devices' sub-systems, sound quality control procedures and
the service capabilities of distributors.
 
     As part of its quality program, Sabratek provides its customers with
extensive in-service and training in the use of its products. This is provided
by both Sabratek's sales force and its distributors.

     The Company has registered or applied to register the following trademarks:
SABRATEK(R) and its logo, AutoRamp(R), HOMERUN(R), SEAMLESS DELIVERY SYSTEM(TM),
PumpMaster(TM), MediVIEW(R) and TCS Total Compliance System(TM). The Company has
also filed a foreign trademark application for the name SABRATEK(TM) and its
logo in Japan. See "Risk Factors--Intellectual Property."
 
COMPETITION
 
     The Company faces substantial competition. At the present time, the Company
considers its primary competitors to be other marketers of infusion pumps. The
Company believes there are several major competitors in the market for infusion
pump devices, including, but not limited to: Abbott Laboratories; Advanced
Medical, Inc.; Baxter International Inc.; I-Flow Corp.; McGaw, Inc., a
subsidiary of IVAX Corporation, and SIMS Deltec. See "Risk Factors -- Highly
Competitive Markets; Technological Risk."
 
     Despite the greater size and market share of its competitors, Sabratek
believes that its products compete favorably against the products offered by its
competitors. Sabratek has strategically designed its stationary and ambulatory
pump products to offer cost efficient and convenient transferability of
training/operational procedures and functions. Unlike manufacturers that offer
only a stationary or an ambulatory pump, or offer both but whose products lack
operational integration, Sabratek's SEAMLESS DELIVERY SYSTEM product design
provides health care providers with product standardization which the Company
believes to be critical in achieving operating efficiencies. Sabratek believes
that its products also compete favorably with the products of larger, more
established companies on the basis of other advanced product features.
 
REIMBURSEMENT
 
     The Company's current products are generally purchased by health care
providers who are reimbursed by third-party payors, including indemnity
insurance companies, managed care organizations and government agencies. Such
health care providers recover the cost of purchasing the Company's products
through reimbursement for services provided using the Company's products. A
recent trend is for providers to contract for services on a capitated basis.
Under those contracts, providers receive a fixed fee for providing service to
patients. In those situations, the providers' profit or loss on the contract is
dependent upon managing its costs.
 
     HCFA coordinates a system of reimbursement for outpatient hospital
procedures, physician office procedures and devices used in conjunction
therewith. Under this system, HCFA determines coverage eligibility, issues
coverage instructions and assigns billing codes called the HCFA Common
Procedures Coding System ("HCPCS") for such procedures and devices under
Medicare and Medicaid. HCFA has established HCPCS billing codes for infusion
devices. Moreover, the HCPCS system is referenced by most third-party payors,
including Medicare and Medicaid, insurance companies and health maintenance
organizations, thereby standardizing coverage identification and billing
identification across a broad spectrum of payor plans. When the use of
FDA-approved infusion devices is prescribed by a physician and determined to be
reasonable and necessary in the treatment of illness, such use is generally
reimbursable under Medicare and Medicaid. Reimbursement by other third-party
payors is dependent upon the coverage provided under the applicable plan. See
"Risk Factors -- Dependence on Third-Party Reimbursement."
 
GOVERNMENT REGULATION
 
     The medical devices and supplies manufactured and marketed by the Company
are subject to regulation by the FDA and, in some instances, by state and
foreign authorities. Pursuant to the FFDCA and the regulations promulgated
thereunder, the FDA regulates the clinical testing, development, manufacture,
packaging, labeling, distribution and promotion of medical devices and supplies.
 
     Pursuant to the FFDCA, medical devices intended for human use are
classified into three categories, Classes I, II and III, on the basis of the
controls deemed necessary by the FDA to reasonably assure their safety and
effectiveness. Class I devices are subject to general controls (for example,
labeling, premarket notification and adherence to good manufacturing practice
("GMP") requirements) and Class II devices are subject to general and special
controls (for example, performance standards, postmarket surveillance, patient
registries, and FDA guidelines). Generally, Class III devices are those which
must receive premarket approval ("PMA") from the FDA to ensure their safety and
effectiveness (for example, life-sustaining, life-supporting and implantable
devices, or new devices which have not been found substantially equivalent to
legally
 
                                       28
<PAGE>   33
 
marketed devices). Electronic infusion devices and disposable tubing sets are
classified by the FDA as Class II medical devices.
 
     If a new Class II medical device is substantially equivalent in terms of
safety and effectiveness to a medical device already legally marketed in the
United States, the FDA requirements may be satisfied through a procedure known
as a "510(k) Submission," in which the applicant provides product information
supporting its claim of substantial equivalency. "Substantial equivalence" means
that a device has the same intended use and the same technological
characteristics as the legally marketed device, or the same intended use and
different technological characteristics, provided that it can be demonstrated
that the device is as safe and effective as the legally marketed device, and
does not raise different questions regarding safety and effectiveness. A
"legally marketed device" to which a new device may be compared for a
determination regarding substantial equivalence is a device that was legally
marketed prior to May 28, 1976, when the Medical Device Amendments were added to
the FFDCA, or a device which has been reclassified from Class III to Class II or
I, or a device which has been found to be substantially equivalent through the
510(k) premarket notification process.
 
     Commercial distribution of a device for which a 510(k) Submission is
required can begin only after the FDA issues an order finding the device to be
"substantially equivalent" to a legally marketed device. The FDA has recently
been requiring a more rigorous demonstration of substantial equivalence than in
the past. This may include a requirement for clinical testing of the device. It
generally takes from four to twelve months from submission of a 510(k) to obtain
a 510(k) clearance, but it may take longer. The FDA may determine that a
proposed device is not substantially equivalent to a legally marketed device, in
which case a PMA may be required, or that additional information is needed
before a substantial equivalence determination can be made, in which case data
from safety and effectiveness tests, including clinical tests, may be required.
The process for preparing and obtaining FDA approval of a PMA is much more
elaborate, time-consuming, and expensive than the process of preparing and
obtaining FDA clearance of a 510(k) Submission and would require the Company,
among other things, to conduct preclinical and clinical trials to demonstrate
the safety and effectiveness of the proposed device. A "not substantially
equivalent" determination or a request for additional information could
significantly delay the market introduction of new products.
 
     The Company received 510(k) clearance to begin marketing the 3030
Stationary Pump in the United States in May, 1992. The Company received 510(k)
clearance for the disposable tubing sets for use with the 3030 Stationary Pump
in March, 1995. In July, 1994, the FDA cleared the 510(k) Submission for the
6060 Ambulatory Pump and disposable tubing sets for use with the 6060 Ambulatory
Pump. In June 1996, the Company received 510(k) clearance for the MediVIEW
software system for use with the 3030 Stationary Pump.
 
     The Company believes that its 510(k) clearance for the 6060 Ambulatory Pump
adequately described the MediVIEW software system and, accordingly, 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.
However, there can be no assurance that the FDA would agree with the Company's
determination. If in the future the FDA concluded 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 files a new 510(k) Submission and obtains
clearance from the FDA. The FDA could also take regulatory action against the
Company for any prior distribution of the MediVIEW software system with the 6060
Ambulatory Pump. Alternatively, the FDA could use its discretion not to take any
regulatory steps with regard to this issue.
 
     The PumpMaster is a hardware and software system designed to perform
diagnostic tests on the Company's infusion pumps. The Company has determined
that the PumpMaster does not qualify as a medical device under the statutory
definition and, therefore, did not file a 510(k) Submission with respect to such
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, it could suspend its commercial distribution until such
time as a 510(k) Submission covering such product has been filed and cleared.
The FDA could also take regulatory action against the Company based on its prior
distribution of the uncleared
 
                                       29
<PAGE>   34
 
product. Alternatively, the FDA could use its discretion not to take any
regulatory steps with respect to this issue.
 
     The FFDCA requires the filing of a new 510(k) Submission when, among other
things, there is a major change or modification in the intended use of the
device or a change or modification, including product enhancements, to a legally
marketed device that could significantly affect its safety or effectiveness. A
device manufacturer is responsible for making the initial determination as to
whether a proposed change to a cleared device or to its intended use
necessitates the filing of a new 510(k) Submission. The Company has made some
enhancements to its currently marketed products without filing 510(k)
Submissions. There can be no assurance that the FDA would agree with the
Company's determinations that these enhancements do not require a 510(k)
Submission. Likewise, if the Company determines that any modifications that it
may make to its cleared devices in the future do not require a new 510(k)
Submission, there can be no assurance that the FDA would agree with the
Company's determinations and would not require a new 510(k) Submission for any
modifications made to the devices. If the FDA requires the Company to file a new
510(k) Submission for any past or future modification to a cleared device, the
Company may be prohibited from marketing the device as modified until it obtains
clearance from the FDA. There can be no assurance that the Company will obtain
510(k) clearance on a timely basis, if at all, for any device modification for
which it files a future 510(k) Submission. If 510(k) 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 intends to develop new products for the future, including new
applications for the MediVIEW software system. The Company's new products,
including new applications for existing products, may qualify as devices that
require FDA clearance or approval prior to marketing . The FDA is currently in
the process of revising the regulatory requirements and review criteria for
software-related medical devices, which could adversely affect the Company's
introduction of new software products, or devices that incorporate software, in
the future. There can be no assurance that market clearance of future products
or product applications will be forthcoming in a timely manner, if at all, or
that FDA's clearance or approval of future products or product applications will
not contain significant limitations in the form of warnings, precautions or
contraindications with respect to conditions of use.
 
     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 85% complete. The
FDA classified the Company's recall as a Class II recall, which is defined as a
situation in which the use of a violative product may cause temporary or
medically reversible adverse health consequences or where the probability of
serious adverse health consequences is remote. FDA reported this recall in the
January 15, 1997 issue of the FDA Enforcement Report. There can be no assurance
that FDA will not take further enforcement action against the Company with
respect to this matter.
 
     Any products manufactured or distributed by the Company pursuant to FDA
clearances or approvals are subject to pervasive and continuing regulation by
the FDA. Device manufacturers are required to register their establishments and
list their devices with the FDA, and are subject to periodic inspections by the
FDA and certain state agencies. The FFDCA requires devices to be manufactured in
accordance with GMP requirements, which impose certain process, procedure and
documentation requirements upon the Company with respect to product development,
manufacturing and quality assurance activities. FDA recently revised its GMP
requirements. The new GMP requirements, which are outlined under the FDA's
Quality Systems regulations, are more extensive than previous requirements.
There can be no assurance that the Company will be able to attain or maintain
compliance with GMP requirements.
 
     In addition, the Medical Device Reporting ("MDR") regulation obligates the
Company to inform the FDA whenever there is reasonable evidence to suggest that
one of its devices may have caused or contributed to death or serious injury, or
where one of its devices malfunctions and, if the malfunction were to recur, the
device would be likely to cause or contribute to a death or serious injury.
There can be no assurance that the
 
                                       30
<PAGE>   35
 
FDA would agree with the Company's determinations as to whether particular
incidents meet the threshold for MDR reporting.
 
     Labeling and promotion activities are also subject to scrutiny by the FDA
and, in certain instances, by the Federal Trade Commission. The FDA actively
enforces regulations prohibiting marketing of products for unapproved or
uncleared uses.
 
     If, as a result of FDA inspections, MDR reports or information derived from
any other source, the FDA believes the Company is not in compliance with the law
or regulations thereunder, the FDA can refuse to clear pending 510(k)
Submissions; withdraw previously cleared 510(k) Submissions; require
notification to users regarding newly found unreasonable risks; request repair,
refund or replacement of faulty devices; request corrective advertisements,
formal recalls or temporary marketing suspension; impose civil penalties; or
institute legal proceedings to detain or seize products, enjoin future
violations, or seek criminal penalties against the Company, its officers or
employees. Civil penalties for FFDCA violations may be assessed by the FDA in
lieu of or in addition to instituting legal action. Civil penalties may range up
to $15,000 per violation for violations of the FFDCA, and a maximum of
$1,000,000 per proceeding. Civil penalties may not be imposed for GMP
violations, unless the violations involve a significant or knowing departure
from the requirements of the FFDCA or a risk to public health. The FDA provides
manufacturers with an opportunity to be heard prior to the assessment of civil
penalties. If civil penalties are assessed, judicial review is available.
 
     The Company exports, or intends to export, its products to Europe, Japan
and other foreign countries. Exports of products that have market clearance from
the FDA in the United States do not require FDA authorization for export.
However, foreign countries often require, among other things, an FDA Certificate
to Foreign Government verifying that the product complies with FFDCA
requirements. To obtain a Certificate to Foreign Government, the device
manufacturer must certify to the FDA that the product has been granted clearance
or approval in the United States and that the manufacturer and the exported
products are in substantial compliance with the FFDCA and all applicable or
pertinent regulations. The FDA may refuse to issue a Certificate to Foreign
Government if significant outstanding GMP violations exist.
 
     International sales of medical devices are subject to the regulatory
requirements of each country. The regulatory review process varies from country
to country. Many countries also impose product standards, packaging and labeling
requirements, and import restrictions on devices. In addition, each country has
its own tariff regulations, duties and tax requirements. The Company plans to
use its distributors to assist in obtaining any necessary foreign governmental
and regulatory approvals. The Company does not currently have its products
registered or approved in any countries requiring an extensive registration or
approval process and has, therefore, not sold any products in such countries.
 
     The Company has received Underwriters Laboratory, Inc. product recognition
under UL 544, Standard for Medical and Dental Equipment as well as product
recognition under Canadian National Standard C22.2 through cUL for both the 3030
Stationary Pump and the 6060 Ambulatory Pump. To maintain "UL" status, the
Company is subject to quarterly inspections by Underwriters Laboratory, Inc.
 
     The Company and its products are also subject to a variety of state and
local laws and regulations in those states or localities where its products are
or will be marketed. Manufacturers are also subject to numerous federal, state
and local laws relating to such matters as safe working conditions,
manufacturing practices, environmental protection, fire hazard control and
disposal of hazardous or potentially hazardous substances. There can be no
assurance that the Company will not be required to incur significant costs to
comply with such laws and regulations.
 
     The Company's Rocap division is currently registered with the FDA as a drug
manufacturer and repackager. 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 would be prohibited from marketing such products
until the necessary approvals were obtained. Such approvals could prove costly
and time consuming to obtain. In addition there can be no assurance that the
Company will obtain such clearances on a timely basis, if at all, for any new
product and/or modification
 
                                       31
<PAGE>   36
 
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 the
use.
 
PRODUCT LIABILITY INSURANCE
 
     The Company faces an inherent business risk of exposure to product
liability claims in the event that the use of its products is alleged to have
resulted in adverse effects. The Company maintains product liability insurance
with coverage of $5.0 million per claim, with an annual aggregate policy limit
of $5.0 million. There can be no assurance that liability claims will not exceed
the coverage limits of such policies or that such insurance will continue to be
available on commercially acceptable terms, if at all. See "Risk Factors --
Product Liability Exposure."
 
LITIGATION
 
     On February 5, 1997, SIMS Deltec filed the 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 for
Communicating with Ambulatory Medical Devices Such as Drug Delivery Devices"
previously issued to SIMS Deltec. The Complaint seeks injunctive relief,
unspecified monetary damages and costs. The Company has not yet formally
responded to the Complaint but intends to vigorously defend against the
allegations contained in the Complaint. Protracted litigation or an adverse
outcome in this matter could have a material adverse impact on the Company's
business, financial condition or results of operations.
 
     The Company is also a party to routine litigation in the ordinary course of
business, none of which, if determined adversely to the Company, would
individually or in the aggregate have a material adverse effect on the Company.
 
EMPLOYEES
 
     As of December 31, 1996, the Company employed 100 persons full-time,
including 48 in manufacturing and operations, 26 in sales and marketing, eight
in research and development, twelve in administration, and six in regulatory
affairs/quality assurance. The Company anticipates hiring additional personnel
following the completion of the Offering, primarily in the areas of sales and
marketing and operations. The Company's employees are not represented by a
union, and the Company considers its relationship with its employees to be
satisfactory.
 
     The Company has entered into employee non-disclosure and non-competition
agreements with each of its full-time employees that (i) prohibit disclosure of
confidential information to anyone outside of the Company both during and
subsequent to employment, (ii) require disclosure to the Company of ideas,
discoveries or inventions relating to or resulting from the employee's work for
the Company and assignment to the Company of all proprietary rights to such
ideas, discoveries or inventions, and (iii) limit competition with the Company's
business by the employee for a maximum period of one year following termination
of their employment.
 
FACILITIES
 
     The Company occupies approximately 38,000 square feet of development,
production, warehouse and administrative space in Niles, Illinois. The facility
lease runs through October 31, 1999. The current annual lease rate for this
space is approximately $217,000 and is subject to annual increases. Sabratek
believes that the leased space is adequate for its anticipated needs into the
foreseeable future.
 
     The Company's Rocap division occupies approximately 7,900 square feet of
production, warehouse and administrative space at two facilities in Woburn,
Massachusetts. The lease terms end July 31, 2000 and August 1, 2000. The current
annual lease rate in aggregate is approximately $64,000. Sabratek intends to
continue to operate the Rocap division's current business from its existing
facilities but may need to lease additional space based upon the planned
expansion of the Rocap division business.

STOCK OPTION PLAN
 
     The Company's Stock Option Plan was adopted in 1992, amended in 1993 and
amended and restated in 1996. The Stock Option Plan, as amended, provides for
the grant of options to purchase up to an aggregate of 1,773,668 shares of
Common Stock. The Plan is administered by the Compensation Committee which makes
discretionary grants ("discretionary grants") of options to employees (including
employees who are officers and directors of the Company) and consultants. The
Stock Option Plan also provides for formula grants ("formula grants") of options
to directors who are not employees of the Company.
 
     Options granted pursuant to discretionary grants may be nonqualified
options or incentive options within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended.
 
                                       38
<PAGE>   43
 
     The selection of participants, allotment of shares, determination of price
and other conditions of purchase of such options are determined by the
Compensation Committee, in its sole discretion. Options granted pursuant to
discretionary grants are exercisable for a period of up to ten years, except
that incentive options granted to optionees who, at the time the option is
granted, own stock representing greater than 10% of the voting power of all
classes of stock of the Company or any parent or subsidiary, are exercisable for
a period of up to five years. The per share exercise price of incentive options
granted pursuant to discretionary grants must be no less than 100% of the fair
market value of the Common Stock on the date of grant, except that the per share
exercise price of incentive options granted to optionees who, at the time the
options are granted, own stock representing greater than 10% of the voting power
of all classes of stock of the Company or any parent or subsidiary, must be no
less than 110% of the fair market value of the Common Stock. The per share
exercise price of non-qualified stock options granted pursuant to discretionary
grants must be no less than 85% of the fair market value of the Common Stock on
the date of grant.
 
     Under the formula grants, each director who is not an employee of the
Company receives automatically upon such director's election to the Board an
option to purchase 7,879 shares of Common Stock. In addition, each director who
serves on a Committee of the Board of Directors receives an option to purchase
945 shares of the Company's Common Stock annually and each Chairman of each such
Committee will receive an additional option to purchase 473 shares of the
Company's Common Stock annually. Such options vest on the earlier of (i) one
year from the date of grant or (ii) the next annual election of directors. Each
such option shall have a term of not more than ten years from the date of
vesting and the exercise price per share of Common Stock for such options shall
be 100% of the fair market value of the Common Stock as determined under the
terms of the Stock Option Plan.
 
     Options granted under the Stock Option Plan are nontransferable, other than
by will or by the laws of descent and distribution, and may be exercised during
the optionee's lifetime, only by the optionee, or in the event of optionee's
legal incapacity to do so, by the optionee's guardian or legal representative.

warrants, there were 8,374,229 shares of Common Stock outstanding, held of
record by approximately 214 stockholders of record. The holders of the Common

submitted to a vote of stockholders. Holders of the Common Stock are entitled to
receive ratably such dividends as may be declared by the Board of Directors out
of funds legally available therefor. In the event of a liquidation, dissolution
or winding up of the Company, holders of the Common Stock are entitled to share
ratably in all assets remaining after payment of all liabilities. The
outstanding shares of the Common stock are fully paid and nonassessable. No
preemptive rights, conversion rights, redemption rights or sinking fund

     As of February 28, 1997, there were warrants outstanding to purchase
544,430 shares of Common Stock at a weighted average exercise price of $5.36 per

REGISTRATION RIGHTS
 
     The Company has entered into a Registration Rights Agreement (the
"Registration Rights Agreement") which may, in certain circumstances, be
applicable to the holders of the equivalent of approximately 1,442,752 shares of
Common Stock. As part of this Offering, the Company is registering the sale of
approximately 532,028 of such shares. As such, following the Offering
approximately 910,724 shares of the Company's outstanding Common Stock will
continue to have the benefit of Registration Rights. Persons who own shares of
Common Stock which will have the benefit of Registration Rights following this
Offering are hereinafter referred to as "Rights Holders." In order for the
Rights Holders to effect a demand for registration, the Registration Rights
Agreement requires that the holders of more than 25% of all of the shares held
under the Registration Rights Agreement request such registration. An unlimited
number of demands may be made; however, the Company has an obligation to
complete only two registrations at the demand of Rights Holders. In addition to
demand registration rights, Rights Holders have unlimited "piggyback"
registration rights pursuant to which the Rights Holders will have the right to
request that the Company register shares of Common Stock under the Act at the
expense of the Company, unless in connection with an underwritten public
offering, the managing underwriter is of the opinion that inclusion of the
shares of Common Stock to which the Rights Holders request registration would
have an adverse impact on the marketing of the securities to be sold in such
public offering.
 
     The Company has entered into a Registration Rights Agreement with Rocap,
pursuant to which the Company agreed to register on Form S-3 in a delayed or
continuous offering (a "Shelf Registration"), 131,593 shares of Common Stock of
the Company, which were distributed to Rocap in connection with the Company's
acquisition of Rocap. Such Shelf Registration would permit the registration of
such securities for resale by Rocap or the Rocap shareholders to whom such
shares may be distributed (the "Rights Holders"). In the event a Shelf
Registration is not permitted under the Securities Act, the Company agreed to
provide alternative registration rights to the Rights Holders. Rights Holders
also have "piggyback" registration rights pursuant to which the Rights Holders
will have the right to require the Company to register shares of Common Stock
held by the Rights Holders on any Registration Statement being filed by the
Company, unless in connection with an underwritten public offering, the managing
underwriter is of the opinion that inclusion of
 
                                       47
<PAGE>   52
 
such shares of Common Stock would have an adverse impact on the marketing of the
securities to be sold for the benefit of the Company in such public offering.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Common Stock is LaSalle National
Bank, Chicago, Illinois.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of the Offering, the Company will have approximately
10,288,005 shares of Common Stock outstanding. Of these shares, the 2,232,028
shares of Common Stock sold in the Offering and the 2,875,000 shares of Common
Stock sold by the Company in its initial public offering in June, 1996, will be
freely tradable without restriction under the Act, unless held by "affiliates"
of the Company (as that term is defined in the Act and regulations promulgated
thereunder).
 
     The shares of Common Stock issued and outstanding prior to the Company's
initial public offering were acquired by existing stockholders without
registration under the Act in reliance upon exemptions from registration and are
"restricted securities" for purposes of the Act. The "restricted securities" may
not be sold unless they are registered under the Act or unless an exemption from
registration, such as the exemption provided by Rule 144 under the Act, is
available.
 
     In general, under Rule 144 as currently in effect, a stockholder (or
stockholders whose shares are aggregated) who has beneficially owned "restricted
securities" for at least two but less than three years (at least one year but
less than two years beginning April 29, 1997), and any affiliate of the Company
who has owned shares for at least two years (one year beginning April 29, 1997),
is entitled to sell within any three-month period a number of shares that does
not exceed the greater of 1% of the outstanding shares of the Company's Common
Stock or the average weekly trading volume in the Company's Common Stock on the
Nasdaq National Market during the four calendar weeks preceding such sale. Such
sales under Rule 144 are also subject to certain provisions regarding the manner
of sale, notice requirements and the availability of current public information
about the Company. A stockholder who is not an affiliate of the Company at the
time of the sale and for at least 90 days prior to a proposed transaction and
who has beneficially owned "restricted securities" for at least three years (two
years beginning April 29, 1997) is entitled to sell such shares under Rule 144
without regard to the limitations described above.
 
     The Company, all Selling Stockholders, all directors, certain officers, and
certain other stockholders have agreed not to offer, pledge, issue, sell,
contract to sell, grant any option for the sale of, or otherwise dispose or
announce any offer, sale, grant of any option to purchase or other disposition
of, directly or indirectly, any Common Stock, or any securities convertible into
or exercisable or exchangeable for Common Stock, until 90 days, or 60 days in
the case of certain stockholders, following the date of the final prospectus
relating to the Offering without the prior written consent of Bear, Stearns &
Co. Inc. ("Bear, Stearns"), subject to certain exceptions (the "Lock-up
Agreements").
 
     On October 2, 1996, the Company's registration statement on Form S-8 under
the Act to register all of the shares of Common Stock issued or reserved for
future issuance under the Stock Option Plan and certain other options currently
outstanding to employees of the Company became effective. After the effective
date of that registration statement, but subject to the provisions of applicable
Lock-up Agreements, shares purchased upon exercise of options covered by such
registration statement generally would be available for resale in public market.
 
     On the anticipated Effective Date, approximately 2,058,840 shares of Common
Stock outstanding before the Offering will be eligible for sale under Rule 144
promulgated under the Act. Shares subject to the Lock-up Agreements may become
available for sale upon the expiration of such lock-ups.
 
     The holders of certain of the Company's outstanding securities also have
the benefit of a Registration Rights Agreements which provide that, subject to
certain conditions, certain holders of the Company's
 
                                       48
<PAGE>   53
 
outstanding securities have rights with respect to registration under the Act.
See "Description of Capital Stock -- Registration Rights."
 
     Sales of substantial amounts of Common Stock in the public market, or the
perception that such sales could occur, could have an adverse impact on the
market price of Common Stock.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Sabratek Corporation:
 
     We have audited the accompanying balance sheets of Sabratek Corporation as
of December 31, 1996 and 1995, and the related statements of operations,
stockholders' equity (deficit), and cash flows for each of the years in the
three-year period ended December 31, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Sabratek Corporation as of
December 31, 1996 and 1995, and the results of its operations and its cash flows
for each of the years in the three-year period ended December 31, 1996 in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
(1) DESCRIPTION OF BUSINESS
 
     Sabratek Corporation (the "Company") designs, manufactures and markets
programmable electronic intravenous infusion pumps, disposable intravenous
administration sets, integrated software, and related accessories. Sales of the
products are made through distributors as well as the Company's own
representatives.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  (a) Revenue Recognition
 
     Revenues are recognized when products are shipped with allowances for
discounts and estimated returns recorded at the time of sale. Contract revenue
from research agreements is recorded when earned and as the related costs are
incurred. Payments received which are related to future performance are deferred
and recognized as revenue when earned over future performance periods.
 
  (b) Cash and Cash Equivalents
 
     Cash and cash equivalents represent funds in demand deposit accounts, money
market accounts and short-term bond mutual funds. Also included are U.S.
Treasury Bills and U.S. Treasury Notes to the extent they mature within 90 days.
 
  (c) Short-term and Long-term Investment in Marketable Securities
 
     Short-term and long-term investments in marketable securities are
classified as available-for-sale and are reported at fair market value.
Unrealized gains on available-for-sale securities are excluded from earnings and
are reported as a separate component of stockholders' equity until realized.
 
  (d) Inventories
 
     Inventories are stated at the lower of cost or net realizable value. Cost
is determined under the first-in, fist-out ("FIFO") method.
 
  (e) Property, Plant and Equipment
 
     Property, plant and equipment are stated at cost less accumulated
depreciation and amortization. Expenditures for maintenance and repairs are
charged to expense as incurred. Depreciation and amortization is provided on a
straightline basis over the estimated useful lives. The estimated useful lives
of the machinery and equipment range from 3 to 5 years. The estimated useful
lives of office furniture, fixtures and equipment is 7 years. Leasehold
improvements are amortized over the life of the lease.
 
  (f) Research and Development
 
     Research and development costs are expensed as incurred. Research and
development costs amounted to $969,059, $2,193,508 and $1,098,167 in 1996, 1995
and 1994, respectively.
 
  (g) Patents
 
     Patents costs in progress are amortized over 16 years. The Company has
assessed that no permanent impairment of the value of the asset has occurred.
Such assessment includes consideration of possible obsolescence, demand, new
technology, competition, and other pertinent economic factors and trends that
may have an impact on the value or remaining lives of the asset.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  (h) Warranty
 
     The provision for estimated warranty costs is recorded at the time of sale
and periodically adjusted to reflect actual experience.
 
  (i) Income Taxes
 
     Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date.
 
  (j) Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  (k) Computation of Net Loss Per Share
 
     Net loss per share is based on the weighted average number of shares
outstanding with common equivalent shares from stock options and warrants
excluded because their effect is antidilutive. Pursuant to Securities and
Exchange Commission Staff Accounting Bulletin No. 83, options and warrants, and
convertible debt granted or issued by the Company during the twelve month period
immediately preceding the initial public offering of the Company's common stock
have been included in the calculation of common shares as if they had been
outstanding for all periods presented. The net loss per share for the year ended
December 31, 1995 has been presented on a pro forma basis in lieu of historical
net loss per share as such historical information is not meaningful due to the
conversion of preferred stock and debt in connection with the Company's initial
public offering.
 
  (l) Reclassifications
 
     Certain amounts for the year ended December 31, 1995 were reclassified to
conform to the current year presentation.

convertible into one share of common stock for every $5.24 of principal and
accrued interest. The debentures were converted into 46,222 shares of common
stock, in the aggregate, upon the Offering, giving effect to the conversion
premium provided for in the debentures.
 
     In January, 1996, the Company issued a convertible subordinated debenture
to a director of the Company in the amount of $100,000 at an interest rate of
10%, until due at June 30, 1996. After June 30, 1996, the debenture would have
paid interest at 13.22% and been extended to 6 years, however, the debenture was
repaid in full, including interest, immediately following the Offering, and
prior to June 30, 1996.
 
     In January and February, 1996, the Company issued convertible subordinated
debentures to directors and independent third-parties in the principal amounts

year maturity and an interest rate of 13.22% per annum and was convertible into
one share of common stock for every $5.24 of principal and accrued interest. The

in the aggregate, upon the Offering. The conversion rate included a conversion
premium not originally provided for in the debentures which resulted in a charge

     In June, 1996, convertible subordinated debentures, issued in 1995, in the
aggregate principal amount of $1,808,292, were converted into 749,348 shares of

(14) STOCK APPRECIATION RIGHTS
 
     In July, 1996, the Company paid, in full, stock appreciation rights
totaling $1,628,463 in aggregate, which were issued pursuant to three separate
agreements during 1995. The agreements provided for a maximum appreciation of
$4.76 per share and required payment at the time of certain qualifying events,
or upon demand of the holder. The obligation created with respect to the
agreements resulted in a non-recurring charge to other income (expenses) in the
Statement of Operations for 1996.
 
(15) BUSINESS AND CREDIT CONCENTRATIONS
 
     As of December 31, 1996 and 1995, individual customers representing at

sales from international markets for the years ended December 31, 1996, 1995 and
1994, respectively. Customers are not concentrated in any specific geographic
location. The customer base is very specific, however, to the health care
industry as the Company's products are used primarily by hospitals and alternate
site healthcare settings such as nursing homes and clinics.
 
(16) RETIREMENT PLAN
 
     The Company implemented a defined contribution plan during 1995 pursuant to
section 401(k) of the Internal Revenue Code, whereby participants may contribute
a percentage of compensation, but not in excess of the maximum allowed under the
Code. The Plan includes a discretionary employer matching contribution program
as determined by the Board of Directors. In 1996 and 1995, no matching
contributions were made to Plan participants' accounts.

     Capital lease obligations of $0 and $178,239 were incurred in 1996 and

rendered. The value of the services rendered equaled $3,465.
 
     In 1994, 635,815 shares of Series A convertible preferred stock were issued

(18) STOCK OPTIONS
 
     The Company adopted the Amended and Restated 1993 Stock Option Plan (the
Stock Option Plan) which provided for the granting of stock options to
employees, nonemployee consultants, and directors of the Company. Options vest
over various periods as defined in the agreements and expire as determined by
the Board on an individual basis, but not to exceed 10 years. Total shares of
common stock reserved at December 31, 1996 for issuance on the exercise of stock
options was 1,773,668.
 
     The Company applies APB Opinion No. 25 and related interpretations in
accounting for its Stock Option Plan. Accordingly, no compensation cost has been
recorded. Had compensation cost for the Company's Stock Option Plan been
determined consistent with FASB Statement No. 123, the Company's net loss and
loss per share would have been increased to the pro forma amounts indicated
below.
 
     The compensation cost of each option grant is estimated on the date of
grant using the Black-Scholes option pricing model with the following weighted
average assumptions used for grants in 1996 and 1995.

</TABLE>
 
     Pro forma net loss and loss per share reflect only options granted in 1996
and 1995. Therefore, the full impact of calculating compensation cost for stock
options under SFAS No. 123 is not reflected in the pro forma net loss amounts
presented above because compensation cost is reflected over the options' vesting
period of up to 4 years and compensation cost for options granted prior to
January 1, 1995 is not considered.

(20) INCOME TAXES
 
     A deferred tax asset stemming from the Company's net operating loss
carryforward, research and development credit carryforward, and other accruals
has been reduced by a valuation account to zero due to uncertainties regarding
the utilization of the deferred assets. The deferred tax asset and the
corresponding valuation allowance were approximately $5,851,000 and $5,201,542
as of December 31, 1996 and 1995, respectively.
 
     The sale of the Company's common stock will result in an ownership change
for the Company, as defined for tax purposes. As a result an annual limitation
will be placed on the utilization of the existing net operating loss
carryforwards and credit carryforwards. This limitation may cause a portion of
the existing net operating loss and credit carryforwards to expire prior to
utilization.
 
     The net operating loss and research and development credit carryforwards
will expire as follows:

(22) SUBSEQUENT EVENTS (UNAUDITED)
 
  Acquisition
 
     In February, 1997, the Company purchased substantially all of the assets of
Rocap, Inc., a Massachusetts company which produces various types of
pre-packaged syringes. Consideration paid by the Company is summarized as
follows:
 
        (1) $100,000 cash.
 
        (2) Forgiveness of $300,000 in debt, owed to the Company in the form of
            a bridge loan agreement entered into on January 15, 1997.
 
        (3) Assumption of approximately $661,000 in net liabilities.
 
        (4) $2,900,000 in cash or stock of the Company.
 
     The stock value as determined by the Asset Purchase Agreement for payment
in shares was $22.0375 per share and, as such, 131,593 shares are held in
escrow. The final number of Company shares deliverable to Rocap, Inc. will be
determined by the Company's stock price at July 1, 1997. The Company has the
option to pay in cash, rather than shares.
 
     In February, 1997, the Company granted stock options to two former Rocap,
Inc. employees, one of which was elected an officer of the Company. In
aggregate, 220,000 option shares were granted at an exercise price of $22.25,
under the Company's Amended and Restated 1993 Stock Option Plan. The stock
options vest over a period of 3 to 4 years. Pursuant to the officer's employment
agreement, the Company could be obligated to purchase 100,000 option shares at
$18.00 each.
 
  Litigation
 
     On February 5, 1997, SIMS Deltec filed a complaint (the "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 for
Communicating with Ambulatory Medical Devices Such as Drug Delivery Devices"
previously issued to SIMS Deltec. The Complaint seeks injunctive relief,
unspecified monetary damages and costs. The Company has not yet formally
responded to the Complaint but intends to vigorously defend against the
allegations contained in the Complaint. Although the outcome of these
proceedings cannot be determined, management believes that the outcome should
not have a material adverse effect on the Company's financial position.
 
  Credit Facility
 
     The Company received a commitment for a credit facility with up to $9.5
million of available borrowings. Borrowings under this facility bear interest at
the bank's prime rate and the facility matures in April, 1999. No amounts have
been borrowed under this facility.

To the Board of Directors
      ROCAP, Inc.
      Five Constitution Way
      Woburn, MA 01801
 
     We have audited the accompanying balance sheet of ROCAP, Inc. (an S
corporation) as of December 31, 1996, and the related statements of loss and
accumulated deficit, and cash flows for the year then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statements presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of ROCAP, Inc. as of December
31, 1996, and the results of its operations and its cash flows for the year then
ended, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of Organization
 
     The Company was incorporated in 1994 under the laws of the Commonwealth of
Massachusetts. The Company has developed an alternative for the in-hospital
pharmacy production process for mixing and packaging pharmaceuticals into
dilutent solutions for intravenous administration.
 
  Basis of Accounting
 
     The Company maintains its records on the accrual basis of accounting.
 
  Accounts Receivable
 
     An allowance for uncollectible accounts in the amount of $50,000 has been
provided at December 31, 1996.
 
  Inventory
 
     Inventories are valued at lower of cost or market on the first-in,
first-out (FIFO) basis.
 
  Property and Equipment
 
     Property and equipment is recorded at cost. Depreciation is computed in
accordance with the Modified Accelerated Cost Recovery System (MACRS) using
various methods and lives as provided in the Internal Revenue Code. Maintenance
and repairs are charged to operations when incurred while significant renewals
and betterments are capitalized.
 
  Income Taxes
 
     The shareholders of the Corporation elected to have the Corporation taxed
as a "S Corporation" for federal and state tax reporting purposes. As such, the
net income of the corporation is taxed at the shareholder level, thereby
eliminating the liability for federal and state corporate income taxes.
 
  Cash Equivalents
 
     For purposes of the statements of cash flows, the Corporation considers all
short-term instruments purchased with a maturity of three months or less to be
cash equivalents. There were no cash equivalents at December 31, 1996.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
2. PREPAID EXPENSES
 
     Prepaid expense at December 31, 1996 consists of prepaid insurance.

                                  (UNAUDITED)
 
The Proforma adjustments reflect the following:
 
(1)  On February 25, 1997, the company consummated an agreement to acquire the
     assets of Rocap. This acquisition was accounted for using the purchase
     method of accounting. The total purchase price of $3,450,000 was paid for
     in a combination of Sabratek stock (assumed to be 131,593 shares currently
     held in escrow) and cash. In addition, Sabratek assumed $661,000 in net
     liabilities. An allocation of the purchase price has been made based upon
     the estimated fair value of the net assets acquired in excess of the
     purchase price over the estimated fair value of the net assets acquired of
     $4,111,000 recorded as goodwill.
 
(2)  Represents amortization, on a straight line basis over 15 years, of the
     goodwill arising out of Rocap.

ITEM 14. 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.

ITEM 17. UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes to provide to the underwriter
at the closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the underwriter to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Act may be
provided 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.
 
     The undersigned registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new 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.

Dear Sirs:

     Sabratek Corporation, a corporation organized and existing under the laws
of Delaware (the "Company"), proposes, subject to the terms and conditions
stated herein, to issue and sell to the several underwriters named in Schedule
I hereto (the "Underwriters") an aggregate of 1,700,000 shares of its common
stock, par value $.01 per share (the "Common Stock") and the stockholders named
in SCHEDULE II hereto (the "Selling Stockholders") propose to sell severally to
the Underwriters an aggregate of 532,028 shares of Common Stock (together
with the 1,700,000 shares of Common Stock to be issued and sold by the Company,
the "Firm Shares").  In addition, for the sole purpose of covering
over-allotments in connection with the sale of the Firm Shares, the Company
grants the Underwriters the option to purchase up to an additional 334,804
shares (the "Additional Shares") of Common Stock.  The Firm Shares and any
Additional Shares purchased by the Underwriters are referred to herein as the
"Shares".  The Shares are more fully described in the Registration Statement
referred to below.

     1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

     The Company represents and warrants to, and agrees with, the Underwriters
that:

     (a) The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement, and may have filed an amendment or
amendments thereto, on Form S-1 (No. 333-________), for the registration of the
Shares under the Securities Act of 1933, as amended (the "Act").  Such
registration statement, including the prospectus, financial statements and
schedules, exhibits and all other documents filed as a part thereof, as amended
at the time of effectiveness of the registration statement, including any
information deemed to be a part thereof as of the time of effectiveness
pursuant to paragraph (b) of Rule 430A or Rule 434 of the Rules and Regulations
of the Commission under the Act (the "Regulations"), is herein called the
"Registration Statement" and the prospectus, in the form first filed with the
Commission pursuant to Rule 424(b) of the Regulations or filed as part of the
Registration Statement at the time of effectiveness if no Rule

2


<PAGE>   3


424(b) or Rule 434 filing is required, is herein called the "Prospectus".  The
term "preliminary prospectus" as used herein means a preliminary prospectus as
described in Rule 430 of the Regulations.

     (b) At the time of the effectiveness of the Registration Statement or the
effectiveness of any post-effective amendment to the Registration Statement,
when the Prospectus is first filed with the Commission pursuant to Rule 424(b)
or Rule 434 of the Regulations, when any supplement to or amendment of the
Prospectus is filed with the Commission, and at the Closing Date and the
Additional Closing Date, if any, (as hereinafter respectively defined), the
Registration Statement and the Prospectus and any amendments thereof and
supplements thereto complied or will comply in all material respects with the
applicable provisions of the Act and the Regulations and does not or will not
contain an untrue statement of a material fact and does not or will not omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein (i) in the case of the Registration Statement, not
misleading and (ii) in the case of the Prospectus, in light of the
circumstances under which they were made, not misleading.  When any related
preliminary prospectus was first filed with the Commission (whether filed as
part of the registration statement for the registration of the Shares or any
amendment thereto or pursuant to Rule 424(a) of the Regulations) and when any
amendment thereof or supplement thereto was first filed with the Commission,
such preliminary prospectus and any amendments thereof and supplements thereto
complied in all material respects with the applicable provisions of the Act and
the Regulations and did not contain an untrue statement of a material fact and
did not omit to state any 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.  No representation and warranty is
made in this subsection (b), however, with respect to any information contained
in or omitted from the Registration Statement or the Prospectus or any related
preliminary prospectus or any amendment thereof or supplement thereto in
reliance upon and in conformity with information furnished in writing to the
Company by or on behalf of any Underwriter through you as herein stated
expressly for use in connection with the preparation thereof.  If Rule 434 is
used, the Company will comply with the requirements of Rule 434.

     (c) KPMG Peat Marwick LLP and Parent, Neffah & Company, who have 
certified the financial statements and supporting schedules included in the
Registration Statement relating to the Company and Rocap, Inc., a Massachusetts
corporation ("Rocap"), respectively, are independent public accountants as 
required by the Act and the Regulations.

     (d) Subsequent to the respective dates as of which information is given 
in the Registration Statement and the Prospectus, except as set forth in the
Registration Statement and the Prospectus, there has been no material adverse   
change or any development involving a prospective material adverse change in
the business, prospects, properties, operations, condition (financial or other)
or results of operations of the Company, whether or not arising from
transactions in the ordinary course of business, and since the date of the
latest balance sheet presented in the Registration Statement and the
Prospectus, the Company has not incurred or undertaken any liabilities or
obligations, direct or contingent, which are material to the Company, except
for liabilities or obligations which are reflected in the Registration
Statement and the Prospectus.

     (e) This Agreement and the transactions contemplated herein have been 
duly and validly authorized by the Company and this Agreement has been
duly and validly executed and delivered by the Company.

     (f) The execution, delivery, and performance of this Agreement and the
consummation of the transactions contemplated hereby do not and will not (i)
conflict with or result in a breach of any of the terms and provisions of, or
constitute a default (or an event which with notice or lapse of time, or both,
would constitute a default) under, or result in the creation or imposition of
any lien, charge or encumbrance upon any property or assets of the Company
pursuant to, any agreement, instrument, franchise, license or permit to which
the Company is a party or by which it or its properties or assets may be bound
or (ii) violate or conflict with any provision of the certificate of
incorporation or by-laws of the Company or any judgment, decree, order,
statute, rule or regulation of any court or any public, governmental or
regulatory agency or body having jurisdiction over the Company or its
properties or assets.  No consent, approval, authorization, order,
registration, filing, qualification, license or permit of or with any court or
any public, governmental or regulatory agency or body having jurisdiction over  
the Company or its properties

or assets is required for the execution, delivery and performance of this
Agreement or the consummation of the transactions contemplated hereby,
including the issuance, sale and delivery of the Shares to be issued, sold and
delivered by the Company hereunder, except the registration  under the Act of

filings, qualifications, licenses and permits as may be required under state
securities or Blue Sky laws in connection with the purchase and distribution of
the Shares by the Underwriters.

    (g) All of the outstanding shares of Common Stock are duly and validly
authorized and issued, fully paid and nonassessable and were not issued and are
not now in violation of or subject to any preemptive rights (except for any
issuance for which a subsequent waiver of all applicable preemptive rights was
obtained).  The Shares, when issued, delivered and sold in accordance with this
Agreement, will be duly and validly issued and outstanding, fully paid and
nonassessable, and will not have been issued in violation of or be subject to
any preemptive rights.  The Company has an authorized and outstanding
capitalization, including, without limitation, stock options, warrants, and
convertible debt securities, as set forth in the Registration Statement and the
Prospectus.  The Common Stock, the Firm Shares and the Additional Shares
conform to the descriptions thereof contained in the Registration Statement and
the Prospectus.

    (h) The Company has been duly organized and is validly existing as a 
corporation in good standing under the laws of its jurisdiction of
incorporation.  The Company is duly qualified and in good standing as a
foreign corporation in each jurisdiction in which the character or location of
its properties (owned, leased or licensed) or the nature or conduct of its
business makes such qualification necessary, except for those failures to be so
qualified or in good standing which will not in the aggregate have a material
adverse effect on the Company.  The Company has all requisite power and
authority, and all necessary consents, approvals, authorizations, orders,
registrations, qualifications, licenses and permits of and from all public,
regulatory or governmental agencies and bodies, to own, lease and operate its
properties and conduct its business as now being conducted and as described in
the Registration Statement and the Prospectus, and no such consent, approval,
authorization, order, registration, qualification, license or permit contains a
materially burdensome restriction not

<PAGE>   6

adequately disclosed in the Registration Statement and the Prospectus.

    (i) Except as described in the Prospectus, there is no litigation or
governmental proceeding to which the Company is a party or to which any
property of the Company is subject or which is pending or, to the knowledge of
the Company, contemplated against the Company which might result in any
material adverse change or any development involving a material adverse change  
in the business, prospects, properties, operations, condition (financial or
other) or, results of operations of the Company or which is required to be
disclosed in the Registration Statement and the Prospectus.

    (j) The Company has not taken and will not take, directly or indirectly, any
action designed to cause or result in, or which constitutes or which might
reasonably be expected to constitute, the stabilization or manipulation of the
price of the shares of Common Stock to facilitate the sale or resale of the
Shares.

    (k) The financial statements, including the notes thereto, and supporting
schedules included in the Registration Statement and the Prospectus present
fairly the financial position of the Company or Rocap, as applicable, as of the
dates indicated and the results of its operations for the periods specified;
except as otherwise stated in the Registration Statement, said financial
statements have been prepared in conformity with generally accepted accounting
principles applied on a consistent basis; and the supporting schedules included
in the Registration Statement present fairly the information required to be
stated therein.

    (l) Except as described in the Prospectus, no holder of securities of the
Company has any rights to the registration of securities of the Company because
of the filing of the Registration Statement or otherwise in connection with the
sale of the Shares contemplated hereby.

contemplated hereby will not be, subject to registration as an "investment
company" under the Investment Company Act of 1940.

    2. REPRESENTATIONS AND WARRANTIES OF THE SELLING STOCKHOLDERS.

       Each Selling Stockholder, for such Selling Stockholder only and not for
any other Selling Stockholder, represents and warrants to, and agrees with, the
several Underwriters that:

       (a) Such Selling Stockholder has duly and irrevocably executed and 
delivered a custody agreement and power of attorney with respect to the
total number of Shares to be sold by such Selling Stockholder, as set forth in
SCHEDULE II hereto (the "Custody Agreement"), in the form heretofore delivered
to the Representatives, appointing Stephen Holden and Scott Skoogland as such
Selling Stockholder's attorneys-in-fact (each an "Attorney-in-Fact"), each with
authority to execute, deliver and perform this Agreement and to take such
actions as may be necessary or desirable to carry out the provisions hereof on
behalf of such Selling Stockholder, and appointing the Company as custodian (in
such capacity, the "Custodian").  Certificates in negotiable form representing,
or duly exercised warrants representing the right to purchase, the Shares to be
sold by such Selling Stockholder hereunder have been deposited 



7
<PAGE>   8


with the Custodian pursuant to the Custody Agreement for the purpose of
delivery of such Shares pursuant to this Agreement.  All authorizations, orders
and consents necessary for the execution and delivery by such Selling
Stockholder of this Agreement and the Custody Agreement have been duly and
validly given, and such Selling Stockholder has full legal right, power and
authority to enter into this Agreement and the Custody Agreement and to sell,
assign, transfer and deliver to the Underwriters the Shares to be sold by such
Selling Stockholder hereunder.  Such Selling Stockholder agrees (i) that the
Shares represented by the stock or warrant certificates on deposit with the
Custodian have been delivered to the Custodian for your benefit to the extent
such Selling Stockholder is obligated to deliver such Shares to you pursuant to
this Agreement; (ii) that the arrangements made for such custody and the
appointment of the Attorney-in-Fact are irrevocable to the extent described in
the Custody Agreement; and (iii) that the obligations of such Selling
Stockholder hereunder may not be terminated (except as provided in this
Agreement, the Custody Agreement) by any act of such Selling Stockholder, by
operation of law (whether by the death or incapacity of such Selling
Stockholder), or by the occurrence of any other event.  If any individual
Selling Stockholder should die or become incapacitated, or if any other event
should occur, before the delivery of such Shares hereunder, the certificates
for such Shares shall be delivered by the Custodian in accordance with the
terms and conditions of this Agreement as if such death, incapacity or other
event had not occurred, regardless of whether or not the Custodian or the
Attorney-in-Fact shall have received notice thereof.

    (b) There is no litigation, arbitration, claim, governmental or other 
proceeding (formal or informal), or investigation pending, or, to the
Selling Stockholder's knowledge, threatened or in prospect (or any basis
therefor known to the Selling Stockholder) with respect to such Selling
Stockholder or any of their respective business, properties or assets which
would prohibit or delay the sale of Stock or Additional Stock to be sold by the
Selling Stockholder hereunder or materially adversely affect the consummation
of the transactions contemplated hereby.  The Selling Stockholder is not in
violation of, or in default with respect to, any law, rule, regulation, order,
judgment or decree which would prohibit or delay the sale of stock to be sold
by the Selling Stockholder hereunder or materially adversely affect the
consummation of the transactions contemplated hereby.

<PAGE>   9


    (c) Such Selling Stockholder has all requisite power and authority to 
execute and deliver this Agreement and the Custody Agreement and to perform the
obligations of the Selling Stockholder hereunder and thereunder.  All necessary
corporate or other proceedings of such Selling Stockholder have been duly taken
to authorize the execution, delivery and performance of this Agreement and the
Custody Agreement by such Selling Stockholder.  This Agreement and the Custody
Agreement have been duly authorized, executed and delivered by such Selling
Stockholder, are the legal, valid and binding obligations of such Selling
Stockholder, and are enforceable as to such Selling Stockholder in accordance
with their respective terms, except as enforcement may be limited by
bankruptcy, insolvency, reorganization, moratorium or similar laws relating to
or affecting creditors' rights generally, by general principles of equity
whether such enforceability is considered in a proceeding in law or equity and
by the discretion of the court before which any proceeding therefor may be
brought, and except to the extent that rights to indemnity hereunder may be
limited by federal or state securities laws or the public policy underlying
such laws.  No consent, authorization, approval, order, license, certificate or 
permit of or from, or declaration or filing with, any federal, state, local or
other governmental authority or any court or other tribunal is required by such
Selling Stockholder for the execution, delivery or performance of this
Agreement (except filings under the Act and such consents as may be required
under "blue sky" or state securities laws identified to the Selling Stockholder
by counsel to the Underwriters, which have been obtained at or prior to the
date of this Agreement) or the Custody Agreement by such Selling Stockholder. 
No consent of any party to any written or oral contract, agreement, instrument,
lease or license to which such Selling Stockholder is a party, or to which any
of their respective properties or assets are subject, is required for the
execution, delivery or performance of this Agreement or the Custody Agreement;
and the execution, delivery and performance of this Agreement and the Custody
Agreement will not violate, result in a breach of, conflict with or (with or
without the giving of notice or the passage of time or both) entitle any party
to terminate or call a default under any such contract, agreement, instrument,
lease or license or violate or result in a breach of, any documents or violate,
result in a breach of, or conflict with, any law, rule, regulation, order,
judgment or decree binding on such Selling Stockholder.


9
<PAGE>   10



    (d) If such Selling Stockholder deposited any warrants under the Custody
Agreement, the Selling Stockholder is the lawful owner of, and has (or upon
such exercise will have) good and marketable title to, such warrants, and such
warrants have been duly exercised and such exercise will be effective on the
Closing Date.  The Selling Stockholder is (or upon such exercise will be) the
lawful owner of, and has (or upon such exercise will have) good and marketable
title to, the Shares to be sold by such Selling Stockholder pursuant to this
Agreement, free and clear of all liens, security interests, pledges, charges,
encumbrances, stockholders' agreements and voting trusts (except those created
by this Agreement and the Custody Agreement), and when delivered in accordance
with this Agreement, the Underwriters will receive good and marketable title to
the Shares, if any, purchased by them, respectively, from such Selling
Stockholder, free and clear of all liens, security interests, pledges, charges,
encumbrances, stockholders' agreements and voting trusts.

    (e) The Selling Stockholder has never taken nor will take, directly or
indirectly, nor will they cause any affiliated purchaser (as defined in the
Regulations) to take, prior to the termination of the underwriting syndicate
contemplated by this Agreement, any action designed to stabilize or manipulate
the price of any security of the Company, or which has caused or resulted in,
or which might in the future reasonably be expected to cause or result in,      
stabilization or manipulation of the price of any security of the Company, to
facilitate the sale or resale of the Shares.

    (f) All information furnished or to be furnished to the Company by or on 
behalf  of the Selling Stockholder for use in connection with the preparation
of the Registration Statement and the Prospectus does not and will not include
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein not misleading.

    (g) To the best knowledge of the Selling Stockholder, the representations 
and warranties of the Company contained in Section 1 hereof are true and
correct; the Selling Stockholder has reviewed and is familiar with the
Registration Statement and the Prospectus and neither the Prospectus nor any
amendments or supplements thereto includes any untrue statement of a material
fact or omits to state a material fact necessary in order to make the
statements therein, in the light of the 



10
<PAGE>   11



circumstances under which they were made, not misleading; the Selling
Stockholder is not prompted to sell the Shares by any information concerning
the Company or any subsidiary of the Company which is not set forth in the
Prospectus.

    (h) Neither the Selling Stockholder nor any affiliates of the Selling
Stockholder directly, or indirectly through one or more intermediaries,
controls, or is controlled by, or is under common control with, or has any
other association with (within the meaning of Article I, Section 1(m) of the
By-laws of the National Association of Securities Dealers, Inc. (the "NASD")),
any member firm of the NASD.

    (i) Except as may be set forth in the Prospectus, the Selling Stockholder 
has not incurred any liability for a fee, commission or other compensation
on account of the employment of a broker or finder in connection with the
transactions contemplated by this Agreement.

 3. PURCHASE, SALE AND DELIVERY OF THE SHARES.

    (a) On the basis of the representations, warranties, covenants and 
agreements of the Company and the Selling Stockholders herein contained, but
subject to the  terms and conditions herein set forth, (i) the Company agrees
to sell to the Underwriters and the Underwriters, severally and not jointly,
agree to purchase from the Company, at a purchase price per share of $[____],
the number of Firm Shares set forth opposite the respective names of the
Underwriters in Schedule I hereto plus any additional number of Shares which
such Underwriter may become obligated to purchase pursuant to the provisions of
Section 9 hereof, and (ii) each Selling Stockholder agrees to sell to the
Underwriters, and the Underwriters, severally and not jointly, agree to
purchase from Selling Stockholders, at a purchase price per share of $[____],
the number of Firm Shares set forth opposite the respective names of such
Selling Stockholders on SCHEDULE II hereto, to be allocated among the
Underwriters pro rata in accordance with the allocation of Firm Shares set
forth on SCHEDULE I, subject, however, to such adjustment as needed to
eliminate fractional shares.

    (b) Payment of the purchase price for, and delivery of certificates for, the
Shares shall be made at the office of Bear, Stearns & Co. Inc., 245 Park
Avenue, New York, New York 10167, or at such other place as shall be agreed
upon 



11
<PAGE>   12

by you and the Company, at 10:00 A.M. on the third or fourth business day
(as permitted under Rule 15c6-1 under the Exchange Act) (unless postponed in
accordance with the provisions of Section 9 hereof) following the date of the
effectiveness of the Registration Statement (or, if the Company has elected to
rely upon Rule 430A of the Regulations, the third or fourth business day (as
permitted under Rule 15c6-1 under the Exchange Act) after the determination of
the public offering price of the Shares), or such other time not later than ten
business days after such date as shall be agreed upon by you and the Company
(such time and date of payment and delivery being herein called the "Closing
Date").  Payment shall be made to the Company by wire transfer in same day
funds to a bank account specified by the Company at the Company's expense
against delivery to you for the respective accounts of the Underwriters of
certificates for the Shares to be purchased by them.  Certificates for the
Shares shall be registered in such name or names and in such authorized
denominations as you may request in writing at least two full business days
prior to the Closing Date.  The Company will permit you to examine and package
such certificates for delivery at least one full business day prior to the
Closing Date.

     (c) In addition, the Company hereby grants to the Underwriters the option
to purchase up to all or part of the Additional Shares at the same purchase 
price per share to be paid by the Underwriters to the Company for the Firm
Shares as set forth in this Section 3, for the sole purpose of covering
over-allotments in the sale of Firm Shares by the Underwriters.  This option
may be exercised at any time, in whole or in part, on or before the thirtieth
day following the date of the Prospectus, by written notice by you to the
Company.  Such notice shall set forth the aggregate number of Additional Shares
as to which the option is being exercised and the date and time, as reasonably
determined by you, when the Additional Shares are to be delivered (such date
and time being herein sometimes referred to as the "Additional Closing Date");
provided, however, that the Additional Closing Date shall not be earlier than
the Closing Date or earlier than the second full business day after the date on
which the option shall have been exercised nor later than the eighth full
business day after the date on which the option shall have been exercised
(unless such time and date are postponed in accordance with the provisions of
Section 9 hereof).  Certificates for the Additional Shares shall be registered
in such name or names and in such authorized denominations as you may request
in writing at least two full business days prior to the Additional Closing
Date.  The Company



12
<PAGE>   13


will permit you to examine and package such certificates for delivery at least
one full business day prior to the Additional Closing Date.

     The number of Additional Shares to be sold to each Underwriter shall be
the number which bears the same ratio to the aggregate number of Additional
Shares being purchased as the number of Firm Shares set forth opposite the name
of such Underwriter in Schedule I hereto (or such number increased as set forth
in Section 9 hereof) bears to 1,700,000, subject, however, to such adjustments
to eliminate any fractional shares as you in your sole discretion shall make.

     Payment for the Additional Shares shall be made by wire transfer in same
day funds to a bank account specified by the Company at the Company's expense,

the Company will use its best efforts to cause the Registration Statement

furnished in advance a copy thereof.

    (b) If at any time when a prospectus relating to the Shares is required to
be delivered under the Act any event shall have occurred as a result of which
the Prospectus as then amended or supplemented would, in the judgment of the

omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading, or if it shall be necessary at any time to amend or
supplement the Prospectus or Registration Statement to comply with the Act or

the Commission an appropriate amendment or supplement (in form and substance
satisfactory to you) which will correct such statement or omission and will use
its best efforts to have any amendment to the Registration Statement declared
effective as soon as possible.

      Regulations.

          (ix) The Registration Statement is effective under the Act, and, to

      necessary proceedings of each Selling Stockholder have been duly taken to
      authorize the execution, delivery and performance of this Agreement and
      the Custody Agreement by such Selling Stockholder.  This
      Agreement and the Custody Agreement have been duly authorized, executed
      and delivered by each Selling Stockholder, are the legal, valid and
      binding obligations of such Selling Stockholder, and are enforceable as
      to such Selling Stockholder in accordance with their respective terms,
      except as enforcement may be limited by bankruptcy, insolvency,
      reorganization, moratorium or similar laws relating to or affecting
      creditors' rights generally, by general principles of equity whether such
      enforceability is considered in a proceeding in law or equity and by the
      discretion of the court before which any proceeding therefor may be
      brought, and except to the extent that rights to indemnity hereunder may
      be limited by federal or state securities laws or the public policy
      underlying such laws.  No consent, authorization, approval, order,

      delivery or performance of this Agreement (except filings under the Act
      and such consents as may be required under "blue sky" or state securities
      laws) or the Custody Agreement by such Selling Stockholder.  To the
      knowledge of such counsel, no consent of any party to any written or oral

      Stockholder is party, or to which any of their respective properties or
      assets are subject, is required for



20

      the execution, delivery or performance of this Agreement (except filings
      under the Act and such consents as may be required under "blue sky" or
      state securities laws) or the Custody Agreement by such Selling
      Stockholder.  To the knowledge of such counsel, no consent of any party
      to any written or oral contract, agreement, instrument, lease or license
      to which such Selling Stockholder is party, or to which any of their
      respective properties or assets are subject, is required for the
      execution, delivery or performance of this Agreement or the Custody

      arbitration, claim, governmental or other proceeding (formal or
      informal), or investigation pending, threatened or in prospect (or any
      basis therefor) with respect to each Selling Stockholder or any of their
      respective properties or assets which would prohibit or delay the sale of
      Shares to be sold by such Selling Stockholder or materially adversely
      affect the consummation of the transactions contemplated hereby.

          (xii)  To the knowledge of such counsel, immediately prior to the 
      Closing Date (or the Additional Closing Date, as the case may be), each
      Selling Stockholder had good and valid title to the Shares to be sold
      at such date by such Selling Stockholder under this Agreement, free and
      clear of all liens, encumbrances, security interests or claims (except
      those created by this Agreement and the Custody Agreement), and has full
      right, power and authority to sell, assign, transfer and deliver the
      Shares to be sold by such Selling Stockholder hereunder.

          (xiii) Good and marketable title to such Shares, free and clear of all
      liens, encumbrances, security 



21

      interests or claims, has been transferred to each of the several
      Underwriters who have purchased such Shares in good faith and without
      notice of any such lien, encumbrance, security interest or claim or any
      other adverse claim within the meaning of the Uniform Commercial Code (as
      in effect in the State of Illinois).

      right to require registration of shares of Common Stock or other
      securities of the Company because the filing or effectiveness of the
      Registration Statement or otherwise in connection with the sale of the
      Shares contemplated hereby.

          (xv) In addition, such opinion shall also contain a statement that 
      such counsel has participated in conferences with officers and
      representatives of the Company, representatives of the independent public
      accountants for the Company and the Underwriters at which the contents
      and the Prospectus and related matters were discussed and, no facts have
      come to the attention of such counsel which would lead such counsel to
      believe that either the Registration Statement at the time it became
      effective (including the information deemed to be part of the
      Registration Statement at the time of effectiveness pursuant to Rule
      430A(b) or Rule 434, if applicable), or any amendment thereof made prior
      to the Closing Date as of the date of such amendment, contained an
      untrue statement of a material fact or omitted to state any material fact
      required to be stated therein or necessary to make the statements therein
      not misleading or that the Prospectus as of its date (or any amendment
      thereof or supplement thereto made prior to the Closing Date as of the
      date of such amendment or supplement) and as of the Closing Date
      contained or contains an untrue statement of a material fact or omitted
      or omits to state any material fact required to be stated therein or
      necessary to make the statements therein, in light of the circumstances
      under which they were made, not misleading (it being understood that such
      counsel need express no belief or opinion with respect to the financial
      statements and schedules and other financial data included or
      incorporated by reference therein).

      In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws other than the laws of the United States and
jurisdictions in which they are 



22
<PAGE>   23


admitted, to the extent such counsel deems proper and to the extent specified

certificates of responsible officers of the Company and certificates or other
written statements of officers of departments of various jurisdictions having
custody of documents respecting the corporate existence or good standing of the
Company and its subsidiaries, provided that copies of any such statements or
certificates shall be delivered to Underwriters' Counsel. The opinion of such
counsel for the Company shall state that the opinion of any such other counsel
is in form satisfactory to such counsel and, in their opinion, you and they are
justified in relying thereon.

        (c) All proceedings taken in connection with the sale of the Firm 
Shares and the Additional Shares as herein contemplated shall be satisfactory
in form and substance to you and to Underwriters' Counsel, and the
Underwriters shall have received from said Underwriters' Counsel a favorable
opinion, dated as of the Closing Date with respect to the issuance and sale of
the Shares, the Registration Statement and the Prospectus and such other
related matters as you may reasonably require, and the Company and the Selling
Stockholders shall have furnished to Underwriters' Counsel such documents as
they request for the purpose of enabling them to pass upon such matters.

        (d) At the Closing Date you shall have received a certificate of the

by the Prospectus.

        (e) At the Closing Date, each Selling Stockholder (or the 
attorney-in-fact on behalf of such Selling Stockholder) shall have
furnished to you a certificate dated the Closing Date signed by, or on behalf
of, such Selling Stockholder (or the attorney-in-fact) stating that the

information pertaining to the Company and its subsidiaries set forth in the

financial records of the Company or from schedules furnished by the
Company, and excluding any questions requiring an interpretation by legal
counsel, with the results obtained from the application of specified readings,
inquiries, and other appropriate procedures specified by you set forth in such
letter, and found them to be in agreement.

        (g) Prior to the Closing Date the Company and the Selling Stockholders

warrants, or convertible debt securities of the Company identified by Bear,
Stearns & Co. Inc. an agreement to the effect that such person will not,
directly or indirectly, without your prior written consent, offer, sell, offer
or agree to sell, grant any option to purchase or otherwise dispose (or
announce any offer, sale, grant of an option to purchase or other disposition)
of any shares of Common Stock (or any securities convertible into, exercisable
for or exchangeable or exercisable for shares of Common Stock) for a period of
90 days after the date of the Prospectus.

        (i) The NASD, upon review of the public offering of the Shares, shall 
not have objected to the Underwriters' participation in such offering.

     If any of the conditions specified in this Section 8 shall not have been
fulfilled when and as required by this Agreement, or if any of the
certificates, opinions, written statements or letters furnished to you or to
Underwriters' Counsel pursuant to this Section 8 shall not be in all material
respects reasonably satisfactory in form and substance to you and to
Underwriters' Counsel, all obligations of the Underwriters hereunder may be
cancelled by you at, or at any time prior to, the Closing Date and the
obligations of the Underwriters to purchase the Additional Shares may be
cancelled by you at, or at any time prior to, the Additional Closing Date.
Notice of such cancellation shall be given to the Company in writing, or by
telephone, telex or telegraph, confirmed in writing.

     9. INDEMNIFICATION.

        (a) The Company agrees to indemnify and hold harmless each Underwriter
and each person, if any, who controls any Underwriter within the meaning of
Section 15 of the Act or Section 20(a) of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), against any and all losses, liabilities,
claims, damages and expenses whatsoever as incurred (including but not limited
to attorneys' fees and any and all expenses whatsoever incurred in
investigating, preparing or defending against any litigation, commenced or
threatened, or any claim whatsoever, and any and all amounts paid in settlement
of any 



26
<PAGE>   27


claim or litigation), joint or several, to which they or any of them may
become subject under the Act, the Exchange Act or otherwise, insofar as such
losses, liabilities, claims, damages or expenses (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement for the
registration of the Shares, as originally filed or any amendment thereof, or
any related preliminary prospectus or the Prospectus, or in any supplement
thereto or amendment thereof,  or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading; provided,
however, that the Company will not be liable in any such case to the extent but
only to the extent that any such loss, liability, claim, damage or expense
arises out of or is based upon any such untrue statement or alleged untrue
statement or omission or alleged omission made therein in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
any Underwriter through you expressly for use therein.  This indemnity
agreement will be in addition to any liability which the Company may otherwise
have including under this Agreement.

        (b) Each Selling Stockholder agrees to indemnify and hold harmless each
Underwriter and each person, if any, who controls any Underwriter within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, against
any and all losses, liabilities, claims, damages and expenses whatsoever as
incurred (including but not limited to attorneys' fees and any and all expenses
whatsoever incurred in investigating, preparing or defending against any
litigation, commenced or threatened, or any claim whatsoever, and any and all
amounts paid in settlement of any claim or litigation), joint or several, to
which they or any of them may become subject under the Act, the Exchange Act or
otherwise, insofar as such losses, liabilities, claims, damages or expenses (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of a material fact contained in the registration
statement for the registration of the Shares, as originally filed or any
amendment thereof, or any related preliminary prospectus or the Prospectus, or
in any supplement thereto or amendment thereof, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that any such
loss, liability, claim, 


27
<PAGE>   28


damage or expense arises out of or is based upon any such untrue statement or
alleged untrue statement or omission or alleged omission made therein in
reliance upon and in conformity with written information relating to such
Selling Stockholder furnished to the Company by such Selling Stockholder
expressly for use therein. This indemnity agreement will be in addition to any
liability which such Selling Stockholder may otherwise have including under
this Agreement.

        (c) Each Underwriter severally, and not jointly, agrees to indemnify 
and hold harmless the Company, each Selling Stockholder, each of the
directors of the Company, each of the officers of the Company who shall have
signed the Registration Statement, and each other person, if any, who controls
the Company or any Selling Stockholder within the meaning of Section 15 of the
Act or Section 20(a) of the Exchange Act, against any losses, liabilities,
claims, damages and expenses whatsoever as incurred (including but not limited
to attorneys' fees and any and all expenses whatsoever incurred in
investigating, preparing or defending against any litigation, commenced or
threatened, or any claim whatsoever, and any and all amounts paid in settlement
of any claim or litigation), jointly or several, to which they or any of them
may become subject under the Act, the Exchange Act or otherwise, insofar as
such losses, liabilities, claims, damages or expenses (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement for the
registration of the Shares, as originally filed or any amendment thereof, or
any related preliminary prospectus or the 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 not misleading, in each
case to the extent, but only to the extent, that any such loss, liability,
claim, damage or expense arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made
therein in reliance upon and in conformity with written information furnished
to the Company by or on behalf of any Underwriter through you expressly for use
therein; provided, however, that in no case shall any Underwriter be liable or
responsible for any amount in excess of the underwriting discount applicable to
the Shares purchased by such Underwriter hereunder.  This indemnity will be in
addition to any liability which any Underwriter may otherwise have including
under this Agreement.  The Company and the Selling Stockholders acknowledge



28
<PAGE>   29


that the statements set forth in the last paragraph of the cover page, in the
bold legends at the bottom of page 2, and in the [fifth, eighth, and tenth]     
paragraphs under the caption "Underwriting" in the Prospectus constitute the
only information furnished in writing by or on behalf of any Underwriter
expressly for use in the registration statement relating to the Shares as
originally filed or in any amendment thereof, any related preliminary
prospectus or the Prospectus or in any amendment thereof or supplement thereto,
as the case may be.

        (d) Promptly after receipt by an indemnified party under subsection 
(a), (b) or (c) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against
the indemnifying party under such subsection, notify each party against whom
indemnification is to be sought in writing of the commencement thereof (but the
failure so to notify an indemnifying party shall not relieve it from any
liability which it may have under this Section 9).  In case any such action is
brought against any indemnified party, and it notifies an indemnifying party of
the commencement thereof, the indemnifying party will be entitled to
participate therein, and to the extent it may elect by written notice delivered
to the indemnified party promptly after receiving the aforesaid notice from
such indemnified party, to assume the defense thereof with counsel satisfactory
to such indemnified party. Notwithstanding the foregoing, the indemnified party
or parties shall have the right to employ its or their own counsel in any such
case, but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties unless (i) the employment of such counsel shall
have been authorized in writing by one of the indemnifying parties in
connection with the defense of such action, (ii) the indemnifying parties shall
not have employed counsel to have charge of the defense of such action within a
reasonable time after notice of commencement of the action, or (iii) such
indemnified party or parties shall have reasonably concluded that there may be
defenses available to it or them which are different from or additional to
those available to one or all of the indemnifying parties (in which case the
indemnifying parties shall not have the right to direct the defense of such
action on behalf of the indemnified party or parties), in any of which events
such fees and expenses shall be borne by the indemnifying parties.  Anything in
this subsection to the contrary notwithstanding, an indemnifying party shall
not be liable for any settlement of any claim or action effected without its


29
<PAGE>   30



written consent; provided, however, that such consent was not unreasonably
withheld.

 10. CONTRIBUTION.

     In order to provide for contribution in circumstances in which the
indemnification provided for in Section 9 is for any reason held to be
unavailable from any indemnifying party or is insufficient to hold harmless a
party indemnified thereunder, the Company, the Selling Stockholders and the
Underwriters shall contribute to the aggregate losses, claims, damages,
liabilities and expenses of the nature contemplated by such indemnification
provision (including any investigation, legal and other expenses incurred in
connection with, and any amount paid in settlement of, any action, suit or
proceeding or any claims asserted, but after deducting in the case of losses,
claims, damages, liabilities and expenses suffered by the Company or any
Selling Stockholder any contribution received by the Company or any Selling
Stockholder from persons, other than the Underwriters, who may also be liable
for contribution, including persons who control the Company within the meaning
of Section 15 of the Act or Section 20(a) of the Exchange Act, officers of the
Company who signed the Registration Statement and directors of the Company) as
incurred to which the Company, the Selling Stockholders and one or more of the
Underwriters may be subject, in such proportions as is appropriate to reflect
the relative benefits received by the Company, the Selling Stockholders and the
Underwriters from the offering of the Shares or, if such allocation is not
permitted by applicable law or indemnification is not available as a result of
the indemnifying party not having received notice as provided in Section 9(d)
hereof, in such proportion as is appropriate to reflect not only the relative
benefits referred to above but also the relative fault of the Company, the
Selling Stockholders and the Underwriters in connection with the statements or
omissions which resulted in such losses, claims, damages, liabilities or
expenses, as well as any other relevant equitable considerations.  The relative
benefits received by the Company, the Selling Stockholders and the Underwriters
shall be deemed to be in the same proportion as (x) the total proceeds from the
offering (net of underwriting discounts and commissions but before deducting
expenses) received by the Company and the Selling Stockholders and (y) the
underwriting discounts and commissions received by the Underwriters,
respectively, in each case as set forth in the table on the cover page of the
Prospectus.  The relative fault of the Company or any Selling Stockholder and
of the Underwriters 


30

<PAGE>   31


shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by
the Company, any Selling Stockholder or the Underwriters and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.  The Company, the Selling Stockholders and
the Underwriters agree that it would not be just and equitable if contribution
pursuant to this Section 10 were determined by pro rata allocation
(even if the Underwriters were treated as one entity for such purpose) or by
any other method of allocation which does not take account of the equitable
considerations referred to above. Notwithstanding the provisions of this
Section 8, (i) in no case shall any Underwriter be liable or responsible for
any amount in excess of the underwriting discount applicable to the Shares
purchased by such Underwriter hereunder, and (ii) no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. Notwithstanding the provisions of this Section 8
and the preceding sentence, no Underwriter shall be required to contribute any
amount in excess of the amount by which the total price at which the Shares
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages that such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  For purposes of this Section 10, each person, if
any, who controls an Underwriter within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act shall have the same rights to contribution as
such Underwriter, and each person, if any, who controls the Company within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, each
officer of the Company who shall have signed the Registration Statement and
each director of the Company, shall have the same rights to contribution as the
Company, subject in each case to clauses (i) and (ii) of this Section 10, and
each person, if any, who controls any Selling Stockholder within the meaning of
Section 15 of the Act or Section 20(a) of the Exchange Act shall have the same
rights to contribution as such Selling Stockholder.  Any party entitled to
contribution will, promptly after receipt of notice of commencement of any
action, suit or proceeding against such party in respect of which a claim for
contribution may be made against another party or parties, notify each party or
parties from whom contribution may be sought, but the omission to so notify
such party or parties shall not relieve the party or parties from whom



31
<PAGE>   32


contribution may be sought from any obligation it or they may have under this
Section 10 or otherwise.  No party shall be liable for contribution with
respect to any action or claim settled without its consent; provided, however,
that such consent was not unreasonably withheld.

    11. DEFAULT BY AN UNDERWRITER.

        (a) If any Underwriter or Underwriters shall default in its or their 
obligation to purchase Firm Shares or Additional Shares hereunder, and if the
Firm Shares or Additional Shares with respect to which such default relates do
not (after giving effect to arrangements, if any, made by you pursuant to
subsection (b) below) exceed in the aggregate 10% of the number of Firm Shares
or Additional Shares, the Firm Shares or Additional Shares with respect to
which the default relates shall be purchased by the non-defaulting Underwriters
in proportion to the respective proportions which the numbers of Firm Shares
set forth opposite their respective names in Schedule I hereto bear to the
aggregate number of Firm Shares set forth opposite the names of the
non-defaulting Underwriters.

        (b) In the event that such default relates to more than 10% of the 
Firm Shares or Additional Shares, as the case may be, you may in your
discretion arrange for yourself or for another party or parties (including any
non-defaulting  Underwriter or Underwriters who so agree) to purchase such Firm
Shares or Additional Shares, as the case may be, to which such default relates
on the terms contained herein.  In the event that within 5 calendar days after
such a default you do not arrange for the purchase of the Firm Shares or
Additional Shares, as the case may be, to which such default relates as
provided in this Section 11, this Agreement or, in the case of a default with
respect to the Additional Shares, the obligations of the Underwriters to
purchase and of the Company and the Selling Stockholders to sell the Additional
Shares shall thereupon terminate, without liability on the part of the Company
or the Selling Stockholders with respect thereto (except in each case as
provided in Sections 7, 9(a) and 10 hereof) or the Underwriters, but nothing in
this Agreement shall relieve a defaulting Underwriter or Underwriters of its or
their liability, if any, to the other Underwriters, the Company and the Selling
Stockholders for damages occasioned by its or their default hereunder.



32
<PAGE>   33


        (c) In the event that the Firm Shares or Additional Shares to which 
the default relates are to be purchased by the non-defaulting Underwriters,
or are to be purchased by another party or parties as aforesaid, you, the
Company or the Selling Stockholders shall have the right to postpone the
Closing Date or Additional Closing Date, as the case may be for a period, not
exceeding five business days, in order to effect whatever changes may thereby
be made necessary in the Registration Statement or the Prospectus or in any
other documents and arrangements, and the Company agrees to file promptly any
amendment or supplement to the Registration Statement or the Prospectus which,
in the opinion of Underwriters' Counsel, may thereby be made necessary or
advisable.  The term "Underwriter" as used in this Agreement shall include any
party substituted under this Section 11 with like effect as if it had
originally been a party to this Agreement with respect to such Firm Shares and
Additional Shares.

    12. SURVIVAL OF REPRESENTATIONS AND AGREEMENTS.

        All representations and warranties, covenants and agreements of the
Underwriters, the Company and the Selling Stockholders contained in this
Agreement, including the agreements contained in Section 7, the indemnity
agreements contained in Section 9 and the contribution agreements contained in
Section 10, shall remain operative and in full force and effect regardless of
any investigation made by or on behalf of any Underwriter or any controlling
person thereof, by or on behalf of the Company, any of its officers and
directors or any controlling person thereof, or by or on behalf of any Selling
Stockholders, and shall survive delivery of and payment for the Shares to and
by the Underwriters.  The representations contained in Sections 1 and 2 and the
agreements contained in Sections 7, 9, 10 and 13(d) hereof shall survive the
termination of this Agreement, including termination pursuant to Section 11 or
13 hereof.

    13. EFFECTIVE DATE OF AGREEMENT; TERMINATION.

        (a) This Agreement shall become effective, upon the later of when (i) 
you and the Company shall have received notification of the effectiveness of
the Registration Statement or (ii) the execution of this Agreement.  If either
the initial public offering price or the purchase price per Share has not been
agreed upon prior to 5:00 P.M., New York time, on the fifth 


33
<PAGE>   34


full business day after the Registration Statement shall have become
effective, this Agreement shall thereupon terminate without liability to the
Company or the Underwriters except as herein expressly provided.  Until
this Agreement becomes effective as aforesaid, it may be terminated by the
Company by notifying you or by you notifying the Company.  Notwithstanding the
foregoing, the provisions of this Section 13 and of Sections 1, 7, 9 and 10
hereof shall at all times be in full force and effect.

        (b) You shall have the right to terminate this Agreement at any time 
prior to the Closing Date, or terminate the obligations of the
Underwriters to purchase the Additional Shares at any time prior to the
Additional Closing Date, as the case may be, if (A) any domestic or
international event or act or occurrence has materially disrupted, or in your
opinion will in the immediate future materially disrupt, the market for the
Company's securities or securities in general; or (B) if trading on the New
York or American Stock Exchanges shall have been suspended, or minimum or
maximum prices for trading shall have been fixed, or maximum ranges for prices
for securities shall have been required, on the New York or American Stock
Exchanges by the New York or American Stock Exchanges or by order of the
Commission or any other governmental authority having jurisdiction; or (C) if a
banking moratorium has been declared by a state or federal authority or if any
new restriction materially adversely affecting the distribution of the Firm
Shares or the Additional Shares, as the case may be, shall have become
effective; or (D) (i) if the United States becomes engaged in hostilities or
there is an escalation of hostilities involving the United States or there is a
declaration of a national emergency or war by the United States or (ii) if
there shall have been such change in political, financial or economic
conditions if the effect of any such event in (i) or (ii) as in your reasonable
judgment makes it impracticable or inadvisable to proceed with the offering,
sale and delivery of the Firm Shares or the Additional Shares, as the case may
be, on the terms contemplated by the Prospectus.

        (c) Any notice of termination pursuant to this Section 13 shall be by 
telephone, telex, or telegraph, confirmed in writing by letter.

        (d) If this Agreement shall be terminated pursuant to any of the 
provisions hereof (otherwise than pursuant to (i) notification by you as
provided in Section 13(a) 


34
<PAGE>   35


hereof or (ii) Section 11(b) or 13(b) hereof), or if the sale of the Shares
provided for herein is not consummated because any condition to the obligations
of the Underwriters set forth herein is not satisfied or because of any
refusal, inability or failure on the part of the Company or any Selling
Stockholder to perform any agreement herein or comply with any provision
hereof, the Company and the Selling Stockholders will, subject to demand by
you, reimburse the Underwriters for all out-of-pocket expenses (including the
fees and expenses of their counsel), incurred by the Underwriters in connection
herewith.

    14. NOTICE.

        All communications hereunder, except as may be otherwise specifically
provided herein, shall be in writing and, if sent to any Underwriter, shall be

person shall have or be construed to have any legal or equitable right, remedy
or claim under or in respect of or by virtue of this Agreement or any provision
herein contained.  The term "successors and assigns" shall not include a
purchaser, in its capacity as such, of Shares from any of the Underwriters.

    16. GOVERNING LAW.

                          [ROSS & HARDIES LETTERHEAD]

Sabratek Corporation
5601 West Howard Street
Niles, Illinois  60714

        Re:  Registration Statement on Form S-1

Ladies and Gentlemen:

        We refer to the Registration Statement on Form S-1 (the "Registration
Statement") being filed by Sabratek Corporation, a Delaware corporation, (the
"Company") with the Securities and Exchange Commission under the Securities Act
of 1933, as amended (the "Securities Act"), relating to the offer and sale of
up to 2,034,804 shares of Common Stock, $0.01 par value per share (the "Common
Stock") of the Company (including a 15% underwriters over-allotment option) by
the Company and up to 532,028 shares of Common Stock by certain stockholders of
the Company.

        Each term used herein that is defined in the Registration Statement and
not otherwise defined herein shall have the meaning specified in the
Registration Statement.

        We are familiar with the proceedings to date with respect to the
proposed offering of the Common Stock and have examined such records, documents
and questions of law, and satisfied ourselves as to such matters of procedure,
law and fact, as we have considered relevant and necessary as a basis for the
opinion expressed in this letter.  In such examination, we have assumed the
genuineness of all signatures, the authenticity of all documents submitted to
us as originals, the conformity to originals of all documents submitted to us
as certified copies or photocopies and the authenticity of the originals of
such documents.

        Based on the foregoing, and subject to the qualifications set forth
hereinafter, we are of the opinion that:

        1.  The Company is duly incorporated and validly existing under the
laws of the State of Delaware.
<PAGE>   2
Sabratek Corporation
March  , 1997
Page 2

        2.  The Common Stock has been duly authorized and, when issued and sold
in accordance with the Registration Statement, will be legally issued, fully 
paid and nonassessable shares of Common Stock of the Company.

        We express no opinion as to the application of the securities or blue
sky laws of the various states to the issuance of the Common Stock.

        We hereby consent to the reference to our firm under the caption "Legal
Matters" in the Registration Statement and the related Prospectus, and to the
filing of this opinion as an Exhibit to the Registration Statement.

                                        Very truly yours,

                                        ROSS & HARDIES

                             SABRATEK CORPORATION

                             EMPLOYMENT AGREEMENT

        AGREEMENT, dated as of August 15, 1996 between Steve Holden (the
"Employee"), and Sabratek Corporation (the "Company").

        WHEREAS, the parties wish to provide for the employment of the Employee
by the Company and the Employee, each intending to be legally bound, agree as
follows:

        1.  Employment.  Subject to all of the terms and conditions of this
Agreement, the Company agrees to employ the Employee as the Chief Financial
Officer (the "CFO") and Senior Vice-President of the Company within the general
guidelines to be determined by the Company's Chief Executive Officer, (the
"CEO").

        2.  Duties.  The Employee will devote substantially all of his business
hours to, and make the best use of his energy, knowledge and training in
carrying out all accounting functions of the Company, SEC, MIS, HR, treasury,
investor relations and some business development functions and will not be
actively engaged in other employment with any other entity or concern.  The
Employee will diligently and conscientiously perform the duties of CFO and
Senior Vice-President of the Company within the general guidelines to be
determined by the Company's CEO with cross reporting to the Company's Chief
Operating Officer (the "COO").

        3.  Term.  The Employee's employment shall commence on the date of this
Agreement and shall continue for a period of 17 months, subject to earlier
termination in accordance with Section 4 below.  Thereafter, the term of this
Agreement shall be automatically extended without action by either the Company
or the Employee for consecutive one-year terms, unless either party gives
written notice to the other not to renew such employment within 120 days before
the expiration of the then current term.

        4.  Termination.  Subject to the respective continuing obligations of
the Company and the Employee under Sections 7, 8, 9 and 10 below:

                (a)  This Agreement may be terminated by the Company
        "for cause" effective immediately upon the giving of written notice
        to the  Employee (if termination results from actions described in
        clauses (i) or (ii) of Section 4(d) below) or on 60 days' written
        notice to the Employee (if termination results from actions
        described in clauses (iii) or (iv) of Section 4(d) below), with the
        basis for termination specified in such notice.

                (b)  This Agreement may be terminated upon the Employee's death 
        or in the event the Employee becomes totally disabled.  For purpose of
        this Agreement, "total disability" shall have the meaning defined in
        the long-term disability plan of the Company then covering the
        Employee or, if no such plan exists, shall mean a disability that
        prevents the Employee from performing his duties under Section 2
        of this Agreement and that can be expected to result in death or has
        lasted or can be expected to last for a continuous period of not        
        less than 12 months.
<PAGE>   2
                (c)  This Agreement may be terminated by either the Company or
        the Employee at any time upon 60 day's written notice to the Company or
        the Employee, as the case may be.

                (d)  For purposes of this Agreement "for cause" shall mean (i)
        dishonesty, fraud, misrepresentation, embezzlement or material and
        deliberate injury or attempted injury, in each case, related to the
        Company or its business, (ii) any unlawful or criminal activity of a
        serious nature, (iii) any repeated and demonstrated failure on the
        Employee's part to faithfully discharge the responsibilities of his
        position for such a period of time that the CEO, in good faith
        determines is extremely detrimental to the current and future interests
        of the Company, or (iv) a material breach of any provision of the
        Agreement.

        5.  Compensation.

                (a)  Base Salary.  In consideration of the Employee's services
        under this Agreement, the Company agrees to pay the Employee an annual
        base salary of $140,000 (the "Base Salary"), payable in accordance with
        the standard payroll practices of the Company with a guaranteed
        increase on January 1, 1997, assuming continuing employment.  On the
        first business day of each consecutive employment year, the CEO shall
        review the Base Salary, and, based upon this review the CEO may at his
        sole discretion adjust it accordingly.

                (b)  Bonuses.  In addition to the Base Salary, the Employee
        shall be entitled to receive an annual incentive bonus (the "Incentive
        Bonus"), based upon milestones mutually agreed to by the CEO and the
        Employee annually.

                For each future period, the milestones for earning the
        Incentive Bonus shall be mutually agreed to by the CEO and the Employee
        prior to the commencement of each period, the CEO shall review the
        maximum annual amount of the Incentive Bonus, and, based upon this
        review, the CEO may at his sole discretion increase or decrease such
        maximum annual amount.  In setting the maximum amount of future
        Incentive Compensation and the milestones, the CEO shall consider
        Operational requirements of the Company and the success of the Employee
        in meeting those requirements.

                The Employee's Incentive Bonus target will be 20% of Base
        Salary in previous fiscal year for hitting 80% of plan, 30% for hitting
        plan and 40% for hitting 120% of plan.  Measurement of performance
        against plan is 50% against top-line and 50% against bottom line.  (For
        1996, bonus would be pro-rated based on 6 months of employment).
        
                (c)  Stock Options.

                        (i)  The Employee shall receive 55,000 shares of common
                stock out of the employee option pool at the strike price of
                $8.375.  The stock will vest as follows:  25% upon joining the
                company, 25% on January 1, 1997 and the balance in 3 equal
                annual installments of 16.6667% on January 1 of the following 3
                years.  All options will vest immediately in the case of the
                sale of the company.
<PAGE>   3
                        The company shall keep available such number of shares
                of Common Stock as will be sufficient to satisfy the
                requirements of this Agreement and shall pay all original issue
                and transfer taxes (if any) with respect to the issue and
                transfer of such shares.  In the event that the outstanding
                shares of the Common Stock of the Company are changed into or
                exchanged for a different number of kind of shares or other
                securities of the Company or of another corporation by reason
                of any reorganization, merger, consolidation, recapitalization,
                reclassification, stock split, combination of shares, or
                dividends payable in capital stock, appropriate adjustments
                shall be made in the number and kind of shares as to which the
                grants set forth herein shall be made.

                        (ii)  The Employee shall be eligible for participation
                in additional options if such options become available for
                senior management.

                (d)  Benefit Plans.  The Employee shall be entitled to the
        benefits set forth on Exhibit A attached hereto.

                (e)  Expenses.  The Company shall pay or reimburse the Employee
        for all reasonable expenses (including, without limitation, expenses
        for entertainment, travel, meals and hotel accommodations) that the
        Employee incurs while performing his duties under this Agreement,
        provided that the Employee accounts properly for such expenses to the
        Company in accordance with Company policies.

        6.  Payment Upon Termination.  Upon the termination of the Employee's
employment with the Company, the Employee shall be entitled to receive the

employee to exercise any stock options following such termination shall be
governed by and subject to the terms and conditions of the Plan and the stock
option agreements entered into between the Company and the Employee.

        conditions of such plans, and (iii) any unpaid expense reimbursement. 
        The Employee will have ninety (90) days to exercise all vested options.

                (b)  If the Employee is terminated pursuant to Section

        and the benfits listed in 6(a)(ii) and (iii) above.

                (c)  If the Employee is terminated pursuant to Section 4(b)

        the Base Salary through the end of the month following his death or

thereafter. (ii) The Company shall provide the Employee continued participation
by Employee (and Employee's dependents) in the benefits set forth in paragraph

substantially similar employment.  Employee shall promptly inform the Company
when he obtains other employment.  (iii) Employee shall be permitted to
immediately exercise all vested options granted based upon vesting outlined in
Exhibit A pursuant to paragraph 5(c)(i) and 5(c)(ii) within ninety (90) days of

$20,000.

        (e)     Benefits Upon Change in Control.

                (i)     In the event that a Change in Control occurs, Employee
        shall be permitted to immediately exercise all vested and
        unvested options granted pursuant to paragraphs 5(c)(i), or any other
        options granted by the Company within ninety (90) days of such event,
        in either case regardless of whether any time or other criteria has
        been satisfied; provided, that Employee pays the exercise price per
        share for any unexercised options he wishes to exercise.

                (ii)    If the Employee voluntarily terminates his employment,
        it shall be treated as a termination for cause, with the

        14A promulgated under the Securities Exchange Act of 1934, as amended
        (the "Exchange Act"), whether or not the Company is then subject to 
        such reporting requirement.

                 (ii)   Any person or group acquires beneficial ownership of

                (iv)    The Company enters into an agreement or the CEO and the

                Control" of the Company as set forth in subparagraphs (i),
                (ii), (iii) or (iv).

                        (v)     A change in control shall not be a condition
                whereby (i) above may technically occur, or where the change in
                control is due to an acquisition by the Company, but when the
                CEO and Board retain their position in the new entity.

        7.  Inventions.

                (a)  "Inventions", as used in this Section 7, means any
        discoveries, improvements and ideas (whether or not they are in writing
        or reduced to practice) or works of authorship (whether or not they can
        be patented or copyrighted) that the Employee makes, authors or
        conceives (either alone or with others) and that:

                        (i)     concern directly the Company's business or the
                Company's present or possible future research or development;

                        (ii)    result from any work the Employee performs for
                the Company;

        within six months after the term of this Agreement will be the
        Company's sole and exclusive property.  The Employee will, with respect

                        (i)     keep current, accurate, and complete records,
                which will belong to the Company and be kept and stored on the
                Company's premises while the Employee is employed by the
                Company;

                        (ii)    promptly and fully disclose the existence and
                describe the nature of the Invention to the Company in writing
                (and without request);

                        (iii)   assign (and the Employee does hereby assign) to
                the Company all of his rights to the Invention, any
                applications he makes for patent or copyrights in any country,
                and any patents or copyrights granted to him in any country;

                        (iv)    acknowledge and deliver promptly to the
                 Company any written instruments, and perform any other

                 rights in the Invention against forfeiture, abandonment, or
                 loss and to obtain and maintain letters, patents and/or
                 copyrights on the Invention and to vest the entire right and
                 title to the Invention in the Company.

        The requirements of this subsection 7(b) do not apply to an
        Invention for which no equipment, supplies, facility or trade secret
        information of  the Company was used and which was developed entirely
        on the Employee's own time and (x) which does not relate directly to
        the Company's business or to the Company's actual or demonstrably
        anticipated research or development, or (y) which does not result from
        any work the Employee performed for the Company. Except as previously
        disclosed to the Company in Inventions as having been made, conceived,
        authorized or acquired by the Employee prior to his employment by the
        Company.

        8.   Confidential                                                       

                (a)   "Confidential Information", as used in this Section 8
        means information that is not generally known and that is proprietary
        to the Company or that the Company is obligated to treat as
        proprietary.  This information includes, without limitation:
                         

                        (i)     trade secret information about the Company and
                 its products;

                        (iii)   information concerning the Company's business,
                 as the Company has conducted it during the last five years or
                 as it may conduct it in the future; and

                        (iv)    information concerning any of the Company's
                 past, current or possible future products, including (without
                 limitation) information about the Company's research, 
                 development, engineering, purchasing, manufacturing,
                 accounting, marketing, selling or leasing.

        Any information that the Employee reasonably considers  Confidential
        Information, or that the Company treats as Confidential Information,
        will be presumed to be Confidential Information (whether the Employee
        or others originated it and regardless of how he obtained it.)
        
        
                (b)      Except as required in his duties to the Company, that
        Employee will never, either during or after his employment by the
        Company, use or disclose Confidential Information to any person not
        authorized by the Company to receive it.  When the Employee's
        employment with the Company ends, he will promptly turn over to the
        Company all records and any compositions, articles, devices, apparatus
        and other items that disclose, describe or embody Confidential
        Information, including all copies, reproductions and specimens of   the
        Confidential Information in his possession, regardless of who prepared
        them.

        any country in which the Company directly or indirectly markets or
        services products or provides services,

                        (ii)    in any way interfere or attempt to

will not transact business with the Company personally, or as agent, owner,
partner, or shareholder of any other entity; provided, however, that the
Employee may enter into any business transaction that is, in the opinion of the 
CEO, reasonable, prudent or necessary to the Company, so long as any such 
business transaction is at arms length as though between independent and prudent
individuals.

        11.     Miscellaneous

        consents to the exclusive jurisdiction of that court for this purpose.

                (d)     Construction.    Wherever possible, each provision of
        this Agreement shall be interpreted so that it is valid under 
        applicable law. If any provision of this Agreement is to any extent 
        invalid under applicable law in any jurisdiction, that provision shall
        still be effective to the extent it remains valid.  The remainder of 
        this Agreement also shall continue to be valid, and the entire 
        Agreement shall continue to be valid in other jurisdictions.

        the Company or the Employee in exercising any right or remedy under this
        Agreement shall waive any provision of the Agreement.  Nor will any 
        single or partial exercise by either the Company or the Employee of any
        right or remedy under this Agreement preclude either of them from 
        otherwise or further exercising these rights or remedies, or any other
        rights or remedies granted by any law or any related document.

     In the event that:

     a.)  The LESSEE shall default in the payment of any installment of rent or

          (10) days after written notice thereof; or

     b.)  The LESSEE shall default in the observance or performance of any 
          other of the LESSEE'S covenants, agreements, or obligations hereunder

     otherwise used for arrears of rent or other default.  No termination or
     repossession provided for in this lease shall relieve the LESSEE of its

     for the account and at the expense of the LESSEE.  If the LESSOR makes any
     expenditures or incurs any obligations for the payment of money in
     connection therewith, including but not limited to, reasonable attorney's

     and opportunity to remove any inventory, supplies or product access to
     which LESSEE is required by law or regulation to restrict.

        THIS LEASE AGREEMENT (this "Lease") is made and entered into this 26th
day of June, 1995, by and between Robert W. Murray, Trustee of Constitution
Park Trust Four under Declaration of Trust dated _________ and recorded at
________ Registry of Deeds at Book ________, Page ________ (hereinafter
referred to as "Landlord) and Rocap Inc., a duly organized Massachusetts
corporation, having an office and usual place of business at 5 Constitution
Park, Woburn, Massachusetts (hereinafter referred to as "Tenant").


                                  WITNESSETH

                           ARTICLE I:   PREMISES

        Landlord hereby leases to Tenant and Tenant hereby takes from Landlord
approximately 4700 square feet of rentable area (the "Premises"), outlined in
Exhibit A attached hereto and made a part hereof, within a portion of that
certain building (the "Building") known as Building #4 situated in
"Constitution Park", 5 Constitution Way, Woburn, Massachusetts (the "Property")
together with all the improvements located thereon.

        The Premises are leased subject to any and all existing encumbrances,
conditions, rights, covenants, easements, restrictions and rights of way of
record, and other matters of record, if any, applicable zoning and building
laws, regulations and codes, and such matters as may be disclosed by inspection
or survey.  Landlord warrants and represents, as an essential term of this
Lease that no such item or matter exists or will exist which substantially
limits or restricts Tenant's use of the premises in a manner consistent with
the use identified in Article VI of this Lease Agreement.

                             ARTICLE II:        TERM

2.1     Commencement Date.

        The term of this Lease shall be for five (5) years (the "Term") and
shall commence on August 1, 1995 (the "Commencement Date"), on which date
Landlord shall have completed the Tenant improvements as provided in Exhibit B
attached hereto (that is, has completed the tenant improvements, except for
normal "punch list" items which do not unreasonably or substantially affect use
or aesthetics of the premises, which items shall be completed by Landlord prior
to said date.  The Landlord shall use diligent efforts to complete said
improvements by such date without the necessity of such punch list items) and
shall have obtained reasonably satisfactory evidence confirming the completion
of construction in accordance with the plans which include the
<PAGE>   2
tenant improvements as provided in Exhibit B, in good and workmanlike manner
and in conformity with applicable municipal codes and regulations.  In the
event the Premises are not completed on or before August 1, 1995, Tenant shall
have the right to terminate its obligations under this Lease; provided,
however, that (i) such date shall be extended for a period equal to the
duration of any delays in construction caused by strikes, shortages or
materials, acts of God or other matters not reasonably within the control of
Landlord, and (ii) in the event any delays in completing the Premises are as a
result of substantial change orders or other delays caused by Tenant, 
Tenant's rights to terminate pursuant to this paragraph shall be null and void
to the extent of delays so caused by Tenant.  Landlord shall be deemed to have
satisfactorily completed the construction of the tenant improvements, and
Tenant shall be deemed to have waived all rights and remedies with respect to
deficiencies in such construction, except for deficiencies of which Tenant has
informed Landlord, in writing, not later that thirty (30) days following the
Commencement Date.
        
2.2     Option to Extend.

        A.      Provided Tenant is not then in default of its obligations
hereunder, Tenant shall have the right to extend the Term for one (1) extension
period of five (5) years (the "Option Term") upon the following terms and
conditions:

        (i)     Tenant must notify Landlord of its election to extend the Term
for the Option Term on or before two hundred seventy (270) days before the date
that the original Term expires.

        (ii)    The annual rent due (i.e., Base Rent) for each year of the
Option Term shall be the Base Rent as adjusted to the greater of the following:

                a.      One hundred percent (100%) of the immediately preceding
year's Base Rent; or

                b.      The Fair Market Rental for the Premises (up to $9.50
per square foot triple net) determined as follows:

    The term "Fair Market Rental" as used in this Lease shall mean the fair
    market rental value of the Premises for the Option Term, which shall be
    determined taking into consideration the terms and provisions contained in
    this Lease.    Landlord and Tenant shall consult, at the request of either
    party during the 5th year of the Term for the purpose of determining Fair
    Market Rental for the Option Term, and any value jointly agreed upon in
    writing shall constitute Fair Market Rental for the purposes hereof.  If
    Landlord and Tenant fail to agree upon Fair Market Rental prior to four (4)
    months before the end of the 5th year of the Term, the

                                     -2-
<PAGE>   3
        Fair Market Rental shall be determined by an appraisal using standards
        then commonly used by professional appraisers in determining fair
        market rent in connection with a net lease (having terms substantially
        similar to those contained in this Lease) to an unrelated third party
        of similar improved real property along Route 128, in Massachusetts. 
        If a determination of Fair Market Rental by appraisal is required under
        this Lease, such question shall be submitted to a board of appraisers,
        three (3) in number, one named by Landlord, one named by Tenant, and
        one named by the other two appraisers.  The Fair Market Rental shall be
        an amount equal to the average of the two closest appraisals in dollar
        amount.  This provision for determination by appraisal shall be
        specifically enforceable, and any such determination hereunder shall be
        final and binding upon the parties.  Landlord and Tenant shall
        each pay for the fees and disbursements of the appraiser appointed by
        it and shall share equally in the fees and expenses of any third
        appraiser.

        (iii)   Additional Rent (defined below) due under this Lease shall be
payable during the Option Term in the same manner as herein provided for the
original Term.

        (iv)    All other provisions of this Lease shall also remain in effect
during the Option Term except the right to extend as set forth in this Section
2.2, it being agreed that there are no further rights of extension after the
Option Term.  Unless expressly stated herein to the contrary, all references
in this Lease to the "Term" shall include the Option Term when and if Landlord
receives Tenant's notice of election to extend the Term as herein provided.

2.3     Early Possession.

        Provided there is no interference with the work to be performed by
Landlord, Landlord hereby grants to Tenant the right to enter upon the
Premises prior to the Commencement Date for the purpose of constructing the
"Clean Room" and other improvements to be completed upon the Premises by
Tenant, for installation and storage of personal property and equipment of
Tenant in preparation for occupancy and use thereof in accordance with this
Lease Agreement, said storage and installation being at the sole and exclusive
risk of Tenant, and for reasonable and related purposes.  Such entry shall be
deemed to be pursuant to a license from Landlord to Tenant and shall be at the
risk of Tenant, and any early occupancy of the Premises shall be subject to all
of the provisions of this Lease.

                              ARTICLE III:  RENT


3.1     Base Rent.

        Tenant agrees to pay Landlord, at the address provided for notices
herein, or such other place or to such other person as Landlord may designate,
rent for the Premises ("Base Rent") in accordance with the following schedule:

        Commencing on the Commencement Date and continuing until the fifth
(5th) anniversary of the Commencement Date, Tenant shall pay Base Rent in the
amount of Thirty-Seven Thousand Six Hundred and 00/100 Dollars ($37,600.00) per
annum, payable in equal monthly installments of $3,133.33 each;

        All payments of Base Rent made hereunder shall be made in advance on
the first day of each month during the Term of this Lease without deduction,
set-off, prior notice or demand in lawful money of the United States of
America.  The Base Rent payment for any fractional month at the commencement,
termination or expiration of the Term will be prorated.  Tenant's first payment
of Base Rent and Additional Rent (as hereinafter defined) shall be due and
owing upon the date of execution of this Lease.

3.2     Additional Rent.

        All amounts which Tenant is required to pay pursuant to this Lease
except Base Rent, including Tenant's payments under Sections 3.3, 3.4 and 3.5
hereof and every fine, penalty, interest and cost which may be added for
nonpayment or late payment, will constitute "Additional Rent" hereunder, and if
Tenant fails to pay such Additional Rent when due, Landlord will have the right
to pay the same and will have all the right, powers and remedies with respect
thereto as are provided herein or by law in the case of nonpayment of Base
Rent.

3.3     Common Area Maintenance and Operation Expense Charge.

        A.      Commencing on the Commencement Date, Tenant shall pay to
Landlord, as Additional Rent hereunder, a Common Area Maintenance and Operation
Expense Charge of Two Thousand Eight Hundred Twenty and 00/100 Dollars
($2,280.00) per annum ($.60 per square foot of area within the Premises) (the
"CAM Charge"), payable in equal monthly installments of $235.00 each in the
same manner as payments by Tenant of Base Rent.  Commencing on the third (3rd)
anniversary of the Commencement Date, the CAM Charge shall be increased
pursuant to subsection C hereof.

                                     -4-
<PAGE>   5
     B.      For the purposes of this Section 3.3 only, the following terms
shall have the following meanings:

        (i)     "Adjustment Date" means the third (3rd) anniversary and each
        subsequent anniversary of the Commencement Date.
      
        (ii)    "Base CPI" means the CPI published two (2) months prior to the
        month during which the Commencement Date occurs.

        (iii)   "Comparison CPI" means the CPI published two (2) months prior
        to the month during which an Adjustment Date occurs.

        (iv)   "Consumer Price Index", also referred to as "CPI", means the
        United States Department of Labor Bureau of Labor Statistics" Consumer
        Price Index, All Urban Consumers, All Items, (1982-84 = 100) for
        Boston-Lawrence-Salem, MA-NH.  If the Bureau of Labor Statistics
        substantially revises the manner in which the CPI is determined, an
        adjustment shall be made in the revised index which would produce
        results equivalent, as nearly as possible, to those which would be
        obtained if the CPI had not been so revised.  Without limiting the
        generality of the foregoing, if the 1982-84 average shall no longer be
        used as an index of 100, such change shall constitute a substantial
        revision.  If the CPI becomes unavailable to the public because
        publication is discontinued, or otherwise becomes unavailable, or if
        data is not readily available to enable the parties to calculate the
        adjustment to the revised index referred to above, the parties shall
        substitute a comparable index based upon changes in the cost of living
        or purchasing power of the consumer dollar published by any other
        governmental agency or, if no such index is available, then a
        comparable index published by a major bank, other financial
        institution, university or recognized financial publication and
        generally recognized and used for such adjustments in the Boston
        metropolitan area.  The substitution of such index shall be subject to
        reasonable agreement of the parties thereon or failing such agreement
        to a final determination by a court of competent jurisdiction.

     C.      Consumer Price Index Adjustments.   On each Adjustment Date,
the annual CAM Charge for the twelve months commencing with said Adjustment
Date will equal the product of sixty cents ($.60) multiplied by the number of
leasable square feet within the Premises multiplied by the percentage increase,
if any, in the applicable Comparison CPI over the base CPI.  In no event shall
the annual CAM Charge for any twelve month period be less than


                                      -5-
<PAGE>   6
the annual CAM Charge for the immediately preceding twelve month period.

3.4  Taxes.

     A.   Payment of Taxes.   Commencing on the Commencement Date and
continuing throughout the Term hereof, Tenant will pay to Landlord, as
Additional Rent hereunder, a tax payment of Six Thousand One Hundred Ten and
00/100 Dollars ($6,110.00) per annum ($1.30 per square foot within the
Premises)  (the "Tax Payment"), payable in equal monthly installments of
$509.17 each in the same manner as payments by Tenant of Base Rent hereunder.
Commencing on the first (1st) anniversary of the Commencement Date, in addition
to the aforementioned Tax Payment, Tenant will pay to Landlord, as Additional
Rent, Tenant's Pro Rata Share (as hereinafter defined) of any increase in
taxes, both general and special, all assessments including general, special and
local, governmental charges of any kind and nature whatsoever, and taxes levied
against the rents, occupancy or use of the Premises (hereinafter collectively
referred to as "Taxes"), levied or assessed on the Building or the property on
which the Building is located, whether such taxes are general or special,
ordinary or extraordinary, foreseen or unforeseen, over the Tax Payment set
forth above (the "Tax Increase Payment)").  Tenant shall pay the Tax Increase
Payment to Landlord monthly based on Landlord's reasonable estimates of the
increase in Taxes, subject to adjustment from time to time upon determination
of the actual amount of the increase in Taxes.  Tenant will pay to Landlord,
within ten (10) days after demand therefor (except that the payment for the
period from the last payment to termination of this Lease shall be paid on the
date of termination based on reasonable estimates), as Additional Rent, Tenant's
Pro Rata Share of any water or sewer rents or charges.  For the purposes of
this Lease, "Tenant's Pro Rata Share" shall mean the fraction (expressed as a
percentage) determined from time to time by dividing the number of square feet
of leasable space in the Premises by the number of square feet of leasable
space in the Building.

     In the event that the Landlord obtains an abatement of said taxes, then
Landlord shall rebate to Tenant the proportionate amount of said payments
attributable to said abatement.

     B.   Change in Method of Taxation.   If at any time during the Term of
this Lease, the present method of taxation is changed so that in lieu of the
whole or any part of any taxes, assessments or charges levied, assessed or
imposed upon real estate and the improvements thereon, there is levied,
assessed or imposed on Landlord a capital levy or other tax directly on the
rents received therefrom and/or a franchise tax assessment, levy or charge
measured by or based, in whole or in part, upon such rents for the present or
any future building or buildings on the 





                                      -6-
<PAGE>   7
property on which the Building is located or any other tax or           
assessment, levied or assessed in lieu of any present taxes, then all such      
taxes, assessments, levies, or charges will be deemed to be included within the
term "Taxes" for the purposes hereof.  In the event any such tax cannot legally
be reimbursable by the Tenant, Landlord will have the option to terminate this
Lease.

        C.  Personal Property Taxes.  Tenant shall pay prior to delinquency all 
taxes assessed against and levied upon leasehold improvements, trade fixtures,
furnishings, equipment and all other personal property of Tenant contained in
the Premises or elsewhere.  Tenant shall cause said leasehold improvements,     
trade fixtures, furnishings, equipment and all other personal property to be
assessed and billed separately from the real property of Landlord.  If any of
Tenant's said personal property shall be assessed with Landlord's real
property, Tenant shall pay Landlord the taxes so attributable to Tenant within
ten (10) days after receipt of a written statement setting forth the taxes
applicable to Tenant's property, based upon a reasonable allocation thereof.

3.5  Tenant's Payment of Landlord's Insurance.

        Commencing on the Commencement Date, Tenant shall pay to Landlord, as
Additional Rent hereunder, an insurance payment for the premiums for insurance
maintained by Landlord with respect to the Property (the "Insurance Payment")
in the amount of Seven Hundred Five and 00/100 Dollars ($705.00) per annum ($.15
per square foot of area within the Premises), payable in equal monthly
installments of $58.75 each in the same manner as payments by Tenant of Base
Rent.  Tenant will pay to Landlord within ten (10) days after demand (except
that the payment for the period from the last payment to the termination of
this Lease shall be paid on the date of termination based on reasonable
estimates), as Additional Rent, Tenant's Pro Rata Share (as defined in Section
3.4 hereof) of any increase in said insurance premiums over the Insurance
Payment set forth in the previous sentence.  The charge will be billed annually
by Landlord.  In the event that any action or nonfeasance on the part of Tenant
results in an increase in Landlord's insurance premiums, then Tenant shall pay
to Landlord, as Additional Rent, the amount of any such increase.

3.6  Late Charges and Interest.

        A.  Tenant hereby acknowledges that late payment by Tenant to Landlord
of Base Rent, Additional Rent or any other sums due hereunder shall cause
Landlord to incur costs not contemplated by this Lease, the exact amount of
which will be extremely difficult to ascertain.  Such costs include, but are
not limited to, processing and accounting charges, and late charges which may
be imposed on Landlord by the terms of any mortgage or trust deed covering the
Premises.  Accordingly, if any installment of Base

                                     -7-
<PAGE>   8
Rent, Additional Rent or any other sum due from Tenant, shall not be received
by Landlord or Landlord's designee within ten (10) days after the date any such
payment becomes due, then Tenant shall pay to Landlord a late charge equal to
six and one half percent (6 1/2%) of such overdue amount.  The parties hereby
agree that such late charge represents a fair and reasonable estimate of the
cost Landlord will incur by reason of late payment by Tenant.  Acceptance of
such late charge by Landlord shall in no event constitute a waiver of Tenant's
default with respect to such overdue amount, nor prevent Landlord from
exercising any of the other rights and remedies granted hereunder.

        B.  Tenant shall be obligated to pay to Landlord interest at the rate
of twelve percent (12%) per annum, on all sums above specified and on all sums
and charges Tenant is obligated to pay under the terms of this Lease from the
date that a late charge under the preceding subparagraph becomes due and
payable thereon, until the date said sums and charges are paid in full.

                            ARTICLE IV:  UTILITIES


        Tenant will pay all charges incurred or billed for all water, gas,
heating fuel, electricity, telephone and all other utility services used on or
from the Premises and any maintenance charges for utilities, and will furnish
all electrical light bulbs and tubes.  If any such utility services are not
separately metered to Tenant, the cost thereof shall be separately billed to
Tenant by Landlord, such bills payable by Tenant on each rental payment date. 
Landlord will in no event be liable for any injury, loss or damage caused by
interruption or failure of utility services to the Premises which is not the
result of negligence, action or wrongful inaction of Landlord, nor shall such
interruption or failure terminate, cancel, affect or modify this Lease unless
same is the result of such negligence, action or wrongful inaction of Landlord
and such interruption so caused by Landlord continues for such a substantial or
unreasonable period that such prolonged interruption substantially interferes
with the ability of Tenant to conduct ongoing business operations in the
premises in compliance with the use identified in Article VI hereof.

                         ARTICLE V:  SECURITY DEPOSIT


        Tenant will deposit with Landlord upon execution of this Lease the sum
of Three Thousand One Hundred Thirty-Three and 33/100 ($3,133.33) as security
for Tenant's faithful performance of Tenant's obligations hereunder (the
"Security Deposit").  If Tenant fails to pay Base Rent, Additional Rent or any
other charges due hereunder, or otherwise defaults with respect to any
provision of this Lease, Landlord may use, apply

                                     -8-
<PAGE>   9
or retain all or any portion of the Security Deposit for the payment of any
Base Rent, Additional Rent or other charge in default or for the payment of any
other sum to which Landlord may become obligated to pay be reason of Tenant's
default, or to compensate Landlord for any loss or damage which Landlord may
suffer thereby.  If Landlord so uses or applies all or any portion of the
Security Deposit, Tenant will, within ten (10) days after written demand
therefor, deposit cash with Landlord in an amount sufficient to restore the
Security Deposit to the full amount hereinabove stated and Tenant's failure to
do so will be a material breach of this Lease and shall entitle Landlord to
exercise any and all remedies set forth herein.  Landlord will not exercise any
and all remedies set forth herein.  Landlord will not be required to retain the
Security Deposit in a separate escrow account nor will Tenant be entitled to
interest on the Security Deposit.  If Tenant performs all of Tenant's
obligations hereunder, the Security Deposit, or so much as has not been applied
by Landlord, will be returned to Tenant within fifteen (15) days after the
expiration or earlier termination of the Lease.  In the event of a sale of the
Premises, the Landlord may transfer the balance of the Security Deposit, if
any, to the purchaser and shall thereupon be released from all liability for
the return of the Security Deposit and the Tenant will look solely to said
purchaser for the return thereof.  Tenant hereby agrees not to look to the
mortgagee, as mortgagee, mortgagee in possession, or successor in title to the
property, for accountability for the Security Deposit unless the Security
Deposit has actually been received by said mortgagee as security for Tenant's
performance under this Lease.


                               ARTICLE VI:  USE

6.1     Use.

        The Premises shall be used and occupied only for general offices,
storage, shipping, receipt and production of pharmaceutical products purposes
and for no other use or purpose.  The parties acknowledge that such use shall
include but not be limited to the operation of a "clean room" involving the
production, manufacture, mixing, and/or solution of pharmaceutical products,
the receipt of competent chemicals or productions and the shipping of finished
products, and all activities appurtenant thereto.


6.2     Compliance with Law.

        Landlord warrants and represents, that to the best of its knowledge,
the Building is in compliance with applicable land use, building and zoning
codes, laws and statutes.  Tenant shall, at Tenant's expense, comply promptly
or do these acts or perform that work necessary to comply with all applicable
statutes (including the Americans With Disabilities Act ("ADA")),

                                     -9-
<PAGE>   10
ordinances, rules, regulations, orders and requirements in effect during the
Term or any part of the Term hereof regulating the use or occupancy by Tenant
of the Premises and will, at Tenant's expense, obtain any and all licenses and  
permits necessary for any such use or occupancy; provided, however, that Tenant
shall have no obligation to comply with the ADA with respect to rest rooms or
the Building entrance.  Landlord further warrants and represents that the
improvements to be installed by Landlord as identified in Exhibit B will be
completed by Landlord in compliance with law and in a good and workmanlike
manner, and that during the Term the Landlord shall undertake any and all acts
necessary to keep in order and to maintain the Building and that portion of the
Premises as is constructed and/or maintained by Landlord in compliance
therewith throughout the Term.  Tenant shall at Tenant's expense apply for and
obtain any and all licenses or permits necessary for Tenant's occupancy and use
of the Premises.  Tenant shall not use or permit the use of the Premises. 
Tenant shall not use or permit the use of the Premises in any manner that will
tend to create waste or a nuisance, or that will be unlawful, improper, noisy
or offensive or which shall tend to unreasonably disturb other tenants of the
Building.

6.3  Hazardous Use.

     Tenant shall not receive, store or otherwise handle any product, material
or merchandise which is explosive or highly flammable other than as listed on
Exhibit D attached hereto or permit the Premises to be used for any purpose
which would render the insurance thereon void or cause an increase in the
premiums for such insurance or make the insurance risk more hazardous other
than the uses identified as Section 6.1.  Tenant shall on demand reimburse
Landlord, and all other tenants, any and all extra insurance premiums caused in
any way by Tenant's use of the Premises.

6.4  Landlord's Rules and Regulations.

     Tenant shall faithfully observe and comply with, and cause its employees,
agents and invitees to observe and comply with, the rules and regulations that
Landlord shall from time to time reasonably promulgate.  A copy of Landlord's
rules and regulations in effect as of the date hereof is attached here to as
Exhibit "C".  Landlord  reserves the right from time to time to make all
reasonable modifications to said rules and regulations.  The additions and
modifications to Landlord's rules and regulations shall be binding upon Tenant
upon delivery of a copy of them to Tenant.  Landlord shall use reasonable
efforts to ensure that no tenant make issue which is unlawful, improper, noisy
or offensive or which shall tend to unreasonably disturb Tenant.

     Tenant's obligations regarding the locks as described in

                                     -10-


<PAGE>   11
Rule 4 shall be subject to the provisions of Section 20.3 and Article XXVIII
hereof regarding Landlord's right of entry.  Tenant reserves the right to
withhold keys in order to restrict access in compliance with the terms of said
Article XXVIII.

        Tenant shall have the right to place reasonable decorations and wall
furnishings without being in violation of Rule 5.

        Landlord agrees that the storage and use of the items identified in
Exhibit C hereto shall not be in violation of Rule 8.

        All medical or other wastes produced by Tenant shall be disposed of in
compliance with law.  Said compliance with law shall constitute full compliance
with Rule 14.

        The parties agree that Rule 17 shall apply only to major movements of
office furniture or other large items.  Normal business operations and freight
shipments as part of normal business operations shall not be in violation of
said Rule 17.

        The parties acknowledge that Tenant will make use of the Clean Room
section of the premises for hours in excess of those identified in Rule 18. 
Because said Clean Room is serviced by systems which are installed and
maintained by Tenant, this use is not in violation of said Rule 18.  Use of the
remaining portion of the Premises during said hours shall not be in violation
of same to the extent that said use is auxiliary to the primary use within the
Clean Room during such times.

6.5     Common Areas.

        Landlord grants to Tenant, during the Term of this Lease, a license to
use all areas and facilities outside the Premises that are provided and
designated for the general use and convenience of Tenant and the other tenants
of the Building including sidewalks, landscaped areas, roadways and parking
areas (the "Common Areas").


                           ARTICLE VII:  INSURANCE


7.1     Tenant's Insurance.

        Tenant, at its own expense, shall provide and keep in force with
companies reasonably acceptable to Landlord public liability insurance for the
benefit of Landlord and Tenant jointly against liability for bodily injury and
property damage in the amount at the beginning of the Term of not less than
$2,000,000.00 combined single limit and from time to time during the Term shall
be for such higher limits as may be reasonably required by Landlord.  Tenant
shall keep all of Tenant's fixtures, furniture.


                                     -11-
<PAGE>   12
furnishings, and equipment insured against loss or damage by fire or other
hazards included within the usual "all risk" insurance in an amount not less
than $2,000,000.  Tenant shall furnish Landlord with certificates of such
policies within thirty (30) days after the Commencement Date of this Lease and
whenever reasonably required shall satisfy Landlord that such policies are in
full force and effect.  All such policies shall be obtained from responsible
companies qualified to do business in the Commonwealth of Massachusetts and in
good standing therein and shall be in a form and from a company approved by
Landlord, which approval shall not be unreasonably withheld or delayed.  Such
policies shall name Landlord and Landlord's first mortgagee as additional
insureds and shall be primary and non-contributing with any insurance carried
by Landlord.  All such policies shall further provide that such policies shall
not be cancelled or altered without at least thirty (30) days prior written
notice to Landlord.

7.2     Waiver of Subrogation.

        Insofar as, and to the extent that, the following provision may be
effective without invalidating or making it impossible to secure insurance
coverage obtainable from responsible insurance companies doing business in the
locality in which the Property is located (even though an extra premium may
result therefrom), Landlord and Tenant mutually agree that, with respect to any
hazard or casualty, the loss from which is covered by insurance then being
carried by them, respectively, the party carrying such insurance and suffering
such loss releases the other of and from any and all claims with respect to
such loss to the extent of the insurance proceeds paid with respect thereto;
and they further mutually agree that their respective insurance companies shall
have no right of subrogation against the other on account thereof.


                    ARTICLE VIII:  MAINTENANCE AND REPAIRS

8.1     Landlord's Obligations.

        Within a reasonable time (not to exceed thirty (30) days) following
receipt of written notice from Tenant of the necessity therefor, Landlord shall
make necessary repairs to maintain the structural integrity of the Building and
Premises and mechanical and utility systems servicing the Premises, including
but not limited to roof, foundations, exterior walls and the structure of the
Premises and the Building in good condition and repair.  "Structure" for
purposes of this Lease shall mean and include only the following:  roof framing
and roof (specifically excluding without limitation the ceiling) and bearing
columns and bearing walls (specifically excluding without limitation the
interior surfaces thereof).


                                     -12-
<PAGE>   13
        In the event that the premises or any part thereof shall be destroyed
or damaged or rendered unusable as a result of lack of structural integrity or
necessary repairs under the preceding paragraph, the Tenant shall be entitled to
abatement of a just and proportionate share of base rent and additional rent,
according to the nature and extent of same.  In the event that a substantial
portion becomes unusable due to said causes (a substantial portion of the
premises for the purposes of this Article shall be deemed to be 25% or more,
according to the same standard identified in Article XVI hereof), and Landlord
fails to remedy same within sixty (60) days of Tenant's notice to Landlord, the
Tenant shall have the right to terminate this Lease Agreement upon written
notice to Landlord.

        Landlord shall not be liable to Tenant for any compensation, nor shall
Tenant be entitled to any reduction of Base Rent or Additional Rent, by reason
of inconvenience or annoyance or for loss of business arising from the
necessity of Landlord's entering the Premises for any of the purposes in this
Lease authorized, or for repairing the Premises or any portion of the Building,
however the necessity may occur.  However, Landlord shall use reasonable
efforts to conduct such repairs in such manner and at such times which limit
the impact upon Tenant's business operations, to the extent reasonably
possible.  Said right of entry by Landlord shall also be subject to Article
XXVIII hereof.  In case Landlord is prevented or delayed from making any
repairs, alterations or imporvements, or furnishing any services or performing
any other covenant or duty to be performed on Landlord's part, by reason of any
cause reasonably beyond Landlord's control, Landlord shall not be liable to
Tenant therefor, nor shall the same give rise to a claim in Tenant's favor that
such failure constitutes actual or constructive, total or partial, eviction
from the Premises.  In no event shall Landlord be liable for indirect or
consequential damages.

        Landlord reserves the right to stop any service or utility system, when
reasonably necessary by reason of accident or emergency, or until necessary
repairs have been completed, provided, however, that in each instance of
stoppage, Landlord shall exercise reasonable diligence to eliminate the cause
thereof.  Except in case of emergency repairs, Landlord will give Tenant
resonable advance notice of any contemplated stoppage and will use reasonable
efforts to avoid unnecessary inconvenience to Tenant by reason thereof.

8.2     Tenant's Obligations.
      
        A.  Landlord warrants and represents that as of the Commencement Date,
the electrical, mechanical and utility services installed by Landlord shall be
in good working order without substantial defect.  During the term hereof,
Tenant 



                                      -13-
<PAGE>   14
shall, at its sole cost and expense and without any cost to Landlord, keep in
good order, condition and repair the Premises, and all utility equipment used
exclusively for the interior of the Premises (including all portions of
electrical and mechanical systems located within the Premises or servicing the
Premises exclusively) and all utility lines to the point of connection for
Tenant, at all times during the Term of this Lease, unless specifically made
Landlord's responsibility under Section 8.1 above.  Tenant's responsibility
hereunder shall include, without limitation and at its sole cost, maintenance,
repair and replacement of mechanical equipment required for the Premises,
fixtures, glass (with glass of the same size and quality), floor covering and
ceiling materials, doors and door hardware and the decoration of the interior
of the Premises.  If Tenant refuses or neglects to make or perform such
replacements, repairs, or maintenance, in a manner reasonably satisfactory to
Landlord, Landlord shall the right, upon giving Tenant reasonable written
notice of its election to do so except in situations deemed to be emergency
situations by Landlord, to make such replacement or repairs or perform such
maintenance on behalf of and for the account of Tenant, and Tenant shall pay
Landlord's cost of such work, as Additional Rent, within thirty (30) days of
receipt of a bill therefor.  Said right of entry shall be subject to Article
XXVIII hereof.

     B.  During the Term  of this Lease, Tenant agrees to employ a suitable
contractor reasonably approved by Landlord to perform Tenant's obligations for
maintenance of the heating, cooling and ventilating units on the Premises and
for maintenance of all fire protection systems within the Premises including
the sprinkler system.  Landlord's approval of such contractor shall not be
unreasonably withheld or delayed.  Such maintenance shall include at least
semiannual inspections and cleaning of said units and systems, together with
such adjustments and servicing as each such inspection discloses to be required
and, in addition, all repairs, testing and servicing as shall be necessary or
reasonably required by Landlord or Landlord's insurance underwriter.  A
suitable contractor to be approved by Landlord shall be one who is reliable
and capable of performing Tenant's obligations hereunder at a competitive cost
to Tenant.  Notwithstanding the foregoing to the contrary, at Landlord's
option, Landlord may elect to employ a suitable contractor to perform Tenant's
obligations for maintenance of the heating, cooling and ventilating units
and/or fire protection systems.  If Landlord elects to employ a contractor or
maintain the heating, cooling and ventilating units and/or fire protection
systems, Tenant shall, promptly upon demand, reimburse Landlord, as Additional
Rent hereunder, for all costs and expenses, the sum of $90.38 per month. 
Nothing contained in this paragraph shall be deemed to be a guarantee by
Landlord or its agents or employees of the performance or responsibility of any
contractor approved by or employed by Landlord as herein provided, and Tenant
hereby

                                     -14-



<PAGE>   15
waives all claims for damages against Landlord to persons or property sustained
by Tenant or any person claiming through Tenant resulting from or in any way
concerned with the employment of a contractor pursuant to the provisions of
this Article.  The parties acknowledge that said systems shall serve only that
area outside of the Clean Room within the Premises.  Therefore the calculation
of the charge hereunder shall utilize only the square footage of the area
actually served by said system.  Tenant shall be solely responsible for
installation, operation and maintenance of the system servicing the Clean Room.

8.3     Snow Removal and Grounds Care.

        The removal of snow and ice from the parking areas, access drives and
loading areas bordering upon the Premises shall be the Landlord's
responsibility.  The removal of snow and ice from the sidewalks and/or walkways
immediately bordering upon the Premises shall be the Tenant's responsibility. 
The care and maintenance of the grounds, including lawns, trees, shrubs and
painted areas bordering upon the Premises shall be the Landlord's
responsibility.


8.4     Cleaning Services and Trash Removal.

        The Tenant shall be responsible, at its sole cost, for providing
cleaning services to and trash removal from within the Premises.


                      ARTICLE IX:  ALTERATIONS AND SIGNS


        Tenant will not make any alterations, additions or improvements to the
Premises or install any signs upon the exterior of the Premises  without on
each occasion the prior written consent of the Landlord, which consent shall
not be unreasonably withheld or delayed; provided, however, in no event shall
Tenant be entitled to maintain a sign on the Building.  All permitted
alterations and signs shall be at Tenant's sole cost and expense.  All
alterations or additions made by Tenant shall be performed in a good and
workmanlike manner using materials of equal or better quality than original
construction, and shall be in compliance with all the applicable laws,
ordinances, orders, rules, regulations and requirements applicable thereto and
shall be performed only by contractors and mechanics reasonably approved by
Landlord.  All such contractors and mechanics shall carry adequate liability
insurance, builder's risk insurance and workmen's compensation insurance in
amounts and companies reasonably approved by Landlord.  Landlord shall be
presented with certificates of same prior to the commencement of any work. 
Furthermore, as a condition to such consent, Landlord may require Tenant to
provide to Landlord, at Tenant's expense, a completion bond in form and
substance satisfactory to Landlord.  Landlord

                                     -15-
<PAGE>   16
hereby consents to the installation by Tenant, at Tenant's sole cost and
expense, of one so-called "clean room" within the Premises.

                            ARTICLE X:  INSPECTION


        Landlord and Landlord's agents and representatives will have the right
to enter and inspect the Premises at any reasonable time during business hours
(and all other times in case of emergency) for the purpose of ascertaining the
condition of the Premises, curing any default on the part of the Tenant or
making repairs to the Premises.  During the one year period prior to the end of
the Term hereof, Landlord and Landlord's agents and representatives will have
the right to enter the Premises at any reasonable time during business hours
for the purpose of showing the Premises and will have the right to erect on the
Premises a suitable sign indicating that the Premises are available.  Landlord
will use reasonable efforts to limit the impact of any and all such entries to
the extent reasonably possible.  Landlord's right of entry hereunder shall also
be subject to Article XXVIII hereof.

    ARTICLE XI:  ASSIGNMENT AND SUBLETTING
        
        Tenant shall not assign, transfer, mortgage or pledge this Lease or
sublet the whole or any part of the Premises without the prior written consent
of Landlord, which consent may not be unreasonably withheld or delayed. 
Without limiting the generality of the foregoing, Landlord may specifically
withhold consent if:  (i) Tenant is then in default hereunder; (ii) any notice
of termination of this Lease or termination of Tenant's possession shall have
been given under Section XX hereof, and is then outstanding and not cured;
(iii) the portion of the Premises which Tenant proposes to sublease, including
the means of ingress and egress thereto and the proposed use thereof, and the
remaining portion of the Premises will violate any city, state or federal law,
ordinance or regulation, including, without limitation, any applicable building
code or zoning ordinances; (iv) the proposed use of the Premises by the
subtenant or assignee does not conform with the permitted use set forth in
Section 6.1 hereof or other use reasonably permitted in the building; (v) in
the reasonable judgement of Landlord the proposed subtenant or assignee is of a
character or is engaged in a business which would be deleterious to the
reputation of the Building, or the subtenant or assignee is not sufficiently
financially responsible to perform its obligations under the proposed sublease
or assignment; (vi) the proposed subtenant or assignee is an occupant of the
Building; (vii) the proposed assignee or subtenant is a governmental or
quasi-governmental agency; (viii) the stature, reputation or financial
capability of the prospective assignee or subtenant is not at least equivalent

                                     -16-

<PAGE>   17
to the stature, reputation or financial capacity of Tenant as of the date
hereof; or (ix) the proposed assignee or subtenant's projected use of the
Premises involves the use, storage, generation or disposal of Hazardous
Material as defined in Article XII of this Lease.  Notwithstanding any
permitted assignment or subletting, Tenant will at all times remain liable for
the payment of all Base Rent, Additional Rent, and any other charges due
hereunder and for the compliance with all of Tenant's other obligations under
the terms, provisions and covenants of this Lease.  A transfer of fifty percent
(50%) or more of an interest in the Tenant to any person or entity who is not a
Stockholder at time of execution of this Lease (whether by stock, partnership
interest or otherwise) by any party in interest will be deemed an assignment of
this Lease.  Landlord's consent to any transfer, assignment or sublease will not
be deemed a consent to any subsequent transfer, assignment or sublease.  In the
event of a default under the terms of this Lease, if the Premises or any part
thereof are then assigned or sublet, Landlord, in addition to any other
remedies herein provided, or provided by law, may at its option collect
directly from assignee or subtenant all rents becoming due to Tenant under
such assignment or sublease and apply such rent against any sums due it by
Tenant hereunder, and no such collection shall be construed to constitute a
novation or a release of Tenant from the further performance of its obligations
hereunder.  Landlord will have the right to assign any of its rights and
obligations under this Lease.  If the rent and other sums and all
considerations received by Tenant on account of any such sublease or assignment
shall exceed the Base Rent, Additional Rent and other charges allocable to the
Premises or to the space subject to the sublease, as the case may be,  Tenant
shall pay to Landlord, as Additional Rent hereunder, all of such excess,
monthly as received by Tenant, less Tenant's reasonable expenses incurred in
respect of such sublease or assignment, including brokerage commissions to a
licensed third party real estate broker, advertising and reasonable attorney's
fees, but expressly excluding costs of repairs or fit-up or alterations to the
Premises for such subtenant or assignee.

                       ARTICLE XII: HAZARDOUS MATERIALS.

     12.1  Tenant shall not cause or permit any Hazardous Material to be
brought upon, kept, used, stored, generated or disposed of on, in or about the
Premises by Tenant, its agents, employees, contractors, or invitees, without
first obtaining Landlord's written consent, with the sole exceptions of those
items which are listed on Exhibit E attached hereto, for which items Landlord
hereby grants consent.

     12.2  Any Hazardous Material permitted on the Premises as provided in
Section 12.1, and all containers therefor, shall be used, kept, stored, and
disposed of in a manner that complies

                                      -17-
 
<PAGE>   18
with all federal, state, and local laws or regulations applicable to this
Hazardous Material.

        12.3  Tenant shall not discharge, leak, or emit, or permit to be
discharged, leaked, or emitted, any material into the atmosphere, ground, sewer
system, or any body of water, if that material (as is reasonably determined by
the Landlord, or any governmental authority) does or may pollute or contaminate
the same, or may adversely affect (a) the health, welfare, or safety of
persons, whether located on the Premises or elsewhere, or (b) the condition,
use, or enjoyment of the Building or any other real or personal property.

        12.4  In the event that Tenant's use of hazardous materials changes
from the uses identified on Exhibit E attached hereto, then at the commencement
of each year of the Term, Tenant shall disclose to Landlord the names and
approximate amounts of all Hazardous Material that Tenant intends to store,
use, or dispose of on the Premises in the coming year.  In addition, at the
commencement of each year of the Lease Term, beginning with the second year of
the Lease Term, Tenant shall disclose to Landlord the names and amounts of all
Hazardous Materials that were actually used, stored, or disposed of on the
Premises if those materials were not previously identified to Landlord at the
commencement of the previous year, in the event that same varied from Exhibit E
attached hereto.

        12.5  As used herein, the term "Hazardous Material" means (a) any
"hazardous waste" as defined by the Resource Conservation and Recovery Act of
1976, as amended from time to time, and regulations promulgated thereunder; (b)
any "hazardous substance" as defined by the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended from time to time,
and regulations promulgated thereunder; (c) any oil, petroleum products, and
their by-products; (d) any substance that is toxic, ignitable, reactive or
corrosive; and (e) any substance that is or becomes regulated by any federal,
state, or local governmental authority.

        12.6  Tenant hereby agrees that it shall be fully liable for all costs
and expenses related to the use, storage and disposal of Hazardous Material
kept on the Premises by the Tenant, and the Tenant shall give immediate notice
to the Landlord of any violation or potential violation of the provisions of
this Article XII.  Tenant shall defend, indemnify, and hold harmless Landlord
and its agents, from and against any and all claims, demands, penalties, fines,
liabilities, settlements, damages, costs, or expenses (including, without
limitation, attorneys' and consultants' fees, court costs, and
litigation expenses) of whatever kind or nature, known or unknown, contingent
or otherwise, allegedly or actually arising out of or in any way related to (a)
the presence, disposal, release, or threatened



                                      -18-
<PAGE>   19
release of any such Hazardous Material that is on, from, or affecting the soil,
water, vegetation, buildings, personal property, persons, animals, or otherwise;
(b) any personal injury (including wrongful death) or property damage (real or
personal) arising out of or related to that Hazardous Material; (c) any lawsuit
brought or threatened, settlement reached, or government order relating to that
Hazardous Material; or (d) any violation of any laws applicable thereto.  This
indemnification includes, without limitation, any and all costs incurred because
of any investigation of the site or any cleanup, removal, or restoration
mandated by a federal, state, or local agency or political subdivision.  Without
limitation of the foregoing, if Tenant causes or permits the presence of any
Hazardous Material on the Premises and that results in contamination, Tenant
shall promptly, at its sole expense, take any and all necessary actions to
return the Premises to the condition existing prior to the presence of any such
Hazardous Material on the Premises.  Tenant shall first obtain Landlord's
approval for any such remedial action.  The provisions of this Section 12.6
shall be in addition to any other obligations and liabilities Tenant may have to
Landlord at law or equity and shall survive the transactions contemplated herein
and shall survive the expiration or earlier termination of this Lease.

     12.7 Landlord represents as an essential term hereof that as of the date
hereof no Hazardous Material, including asbestos or urea formaldehyde insulation
(UFFI), is on or within the Premises.

                            ARTICLE XIII: INDEMNITY

     13.1 Tenant will defend, indemnify and save harmless Landlord from and     
against any and all liabilities, obligations, claims, damages, penalties,
causes of action, costs and expenses (including, without limitation, reasonable
attorneys' fees and expenses) imposed upon, incurred by or asserted against
Landlord arising from Tenant's use or occupancy of the Premises or any breach
or default by Tenant of its obligations hereunder or arising from the
negligence or willful omission of Tenant, its agents, contractors, employees or
invitees to the extent that Tenant is negligent or otherwise legally culpable. 
Tenant shall save Landlord harmless from (i) all loss and damage to personal
property, fixtures, equipment and inventory located within the Premises
occasioned by the escape of water or by the bursting of pipes, which burst is
caused by the negligence, breach or wrongful act or wrongful failure to act by
Tenant, and (ii) any nuisance made or suffered on the Premises.

     13.2 Tenant shall also save Landlord harmless and indemnified, to the
extent permitted by law, from and against any and all claims, actions, loss,
damage, liability and expense in
 
                                      -19-
<PAGE>   20
connection with loss of life, personal injury and/or damage to property arising
out of or resulting from any occurrence in, upon or at the Premises or the
occupancy or use of the Premises or any part thereof to the extent that Tenant
is negligent or otherwise legally culpable thereof, or anywhere if caused       
wholly or in part by any wrongful act, neglect or failure to perform the
obligations imposed by this Lease or any breach thereof, or wrongful omission
of Tenant, its officers, agents, employees, subtenants, licenses,
concessionaires, or others occupying space in the Premises.  If Landlord shall
be threatened with or made a party to any litigation commenced by or against
Tenant, or with respect to any matter described above, then Tenant shall
protect and hold Landlord harmless and indemnified and shall defend Landlord
with counsel reasonably acceptable to Landlord, or, at Landlord's option, shall
advance all costs, expenses and reasonable attorney's fees incurred or paid by
Landlord in connection with such litigation.

              ARTICLE XIV:  EXEMPTION OF LANDLORD FROM LIABILITY


        The term "Landlord" as used in this Lease, so far as the covenants or
obligations on the part of Landlord are concerned, shall be limited to mean and
include only the owner or owners at the time in question of the Premises, and
in the event of any transfer or transfers of title thereto, Landlord named
herein (and in case of any subsequent transfer or conveyance, the then grantor)
shall be automatically relieved from and after the date of such transfer or
conveyance of all liability as respects the performance of any covenants or
obligations on the part of Landlord contained in this Lease thereafter to be
performed.  It is expressly understood and agreed that in the case of default
hereunder by Landlord, Tenant shall look solely to the interest of Landlord in
the Premises for satisfaction of any obligation of Landlord to Tenant, and that
neither the Landlord nor anyone claiming under the Landlord shall ever be
personally liable for satisfaction of any such obligation.  Tenant hereby
agrees that Landlord shall not be liable for injury to Tenant's business or any
loss of income therefrom or for damage to the goods, wares, merchandise or
other property of Tenant, Tenant's employees, invitees, customers, or any other
person in or about the Premises, nor, unless through its negligence or other
legally culpable act or omission, shall Landlord be liable for injury to the
person of Tenant, Tenant's employees, agents or contractors and invitees,
whether such damage or injury is caused by or results from fire, steam,
electricity, gas, water or rain, or from the breakage, leakage, obstruction or
other defects of pipes, sprinklers, wires, appliances, plumbing, air
conditioning or lighting fixtures, or from any cause, whether the said damage
or injury results from conditions arising upon the Premises or upon other
portions of the Building, or from other sources or places, and regardless of
whether the cause of such damage or

                                     -20-
<PAGE>   21
injury or the means of repairing the same in inaccessible to Landlord or
Tenant.  Landlord shall not be liable for any damages arising from any act or
neglect of any other tenant, if any, of the Building.

     This paragraph shall be interpreted in such a manner that Landlord shall be
liable only for its own negligence or other legally culpable act or omission,
and for not other cause.

                       ARTICLE XV: LIENS AND ENCUMBRANCES

     15.1 Tenant will not do any act which will in any way encumber the title of
Landlord in and to the Premises nor will the interest or estate of Landlord in
the Premises be in any way subject to any claim by way of lien or encumbrance,
whether by operation of law or by virtue of any express or implied contract by
Tenant.  Any claim to, or lien upon, the Premises arising from any act or
omission of Tenant will accrue only against the leasehold estate of Tenant and
will be subject and subordinate to the paramount title and rights of Landlord in
and to the Premises.

     15.2 Tenant will not suffer or permit any liens to stand against the
Premises, the Building or any part thereof, by reason of any work, labor,
services, or materials done for, or supplied, or claimed to have been done for,
or supplied to Tenant, or anyone holding the Premises, or any part thereof,
through or under Tenant.  If any such lien is at any time filed against the
Premises, or the Building, Tenant will cause the same to be discharged of record
within thirty (30) days after the date of filing the same, by either payment,
deposit or bond.  If Tenant fails to discharge any such lien within such period,
then, in addition to any other right or remedy of Landlord, Landlord may, but
will not be obligated to, procure the discharge of the same by paying the amount
outstanding under said lien, and Tenant shall immediately reimburse Landlord for
the amount paid by Landlord for any of the aforesaid purposes, together with all
legal and other expenses incurred Landlord, including reasonable attorneys'
fees, in defending any such action or in procuring the discharge of such lien,
which reimbursement from Tenant will become due and payable, as Additional Rent
hereunder on the date of payment of any such sums by Landlord.

     15.3 Nothing in this Lease will be deemed to be, or construed in any way as
constituting the consent or request of Landlord, express or implied, by
inference or otherwise, to any person, firm or corporation for the performance
of any labor or the furnishing of any materials for any construction,
rebuilding, alteration or repair of or to the Premises or any part thereof, nor
as giving Tenant any right, power or authority to contract for or permit the
rendering of any services or the furnishing of

                                      -21-
<PAGE>   22
any materials which might in any way give rise to the right to file any lien
against Landlord's interest in the Premises.

             ARTICLE XVI: DAMAGE OR DESTRUCTION AND CONDEMNATION


16.1   Damage or Destruction of Premises

     A.   If all or a substantial part of the leased Premises is destroyed or
damaged by fire or other unavoidable casualty (a substantial part of the
Premises for the purposes of this Article shall be deemed to be twenty-five
(25) percent or more of its insurable value), then within thirty (30) days
after such casualty either landlord or Tenant may elect in writing to terminate
this Lease.

     B.   If Landlord elects to terminate this Lease as aforesaid, the
termination shall be effective as of the time of such election; if Landlord
elects to restore damaged areas, it shall commence the restoration of the
Premises within forty five (45) days after such casualty and use its best
efforts to coordinate the activities of contractors and material suppliers to
accomplish the restoration within a period of time commensurate with the degree
of damage sustained.  In no event, however, shall Landlord be obligated to use
any of its funds for such restoration other than from applicable fire insurance
proceeds.  Notwithstanding the foregoing, Landlord shall not be obliged to
repair or replace Tenant's furniture, furnishings, personal property or
equipment and shall not be obligated to bear the costs of repairing any damage
caused by any act, omission or negligence of Tenant or of Tenant's employees,
contractees, invitees, or licensees, and Landlord may make such repairs at the
expense of Tenant, and the cost thereof shall be collectable as additional rent
due hereunder.

     C.   If any such restoration is delayed for causes beyond the control of
Landlord, such as acts of God, war, civil insurrection or public disorder,
strikes, unavailability of construction materials, shortages within the labor
market, or acts of governmental authorities, then in such event, the completion
of such restoration shall be postponed for the period of time equal to the
period of delay caused by such events.

     D.   If this Lease is not terminated, a just portion of the rent,
according to the nature and extent of the damage, shall be abated until the
Premises shall have been put into proper condition for use and occupation by
Tenant; provided, however, that if such damage or casualty is caused because of
the negligence of Tenant, its employees, contractees, invitees or licensees,
there shall be no such abatement in rent.

     E.   Notwithstanding the foregoing, Landlord may, in Landlord's sole
discretion, repair and/or rebuild the Building in

                                     -22-
<PAGE>   23
the event of either total or partial destruction, subject to Tenant's right of
termination under Paragraph 16.1A. Landlord will not be obligated to rebuild
until the insurance proceeds have been received and in the event such insurance
proceeds are insufficient to completely rebuild or restore the Premises,
Landlord, at Landlord's option, may provide the funds required to completely
rebuild or restore.  If Landlord's mortgagee applies the insurance proceeds to
the mortgage debt, Landlord shall have no obligation to rebuild, and Tenant may
terminate this Lease by notice.

     F.  In the event that (a) Landlord fails to give written notice within
thirty (30) days of its intention to restore the Premises, or (b) Landlord
fails to restore the Premises to a condition substantially suitable for their
intended use within Ninety (90) days of said damage or destruction (or within
such other period of time as Landlord and Tenant may agree in writing), unless
such damage was due to the negligence or intentional acts of Tenant or Tenant's
employees, contractors, invitees, or licensees, Tenant may elect to terminate
this Lease by written notice to Landlord to be given no later than thirty (30)
days after the date last mentioned.  This right to terminate is in addition to
Tenant's rights to terminate under Paragraph 16.1.A and Paragraph 16.1.E.

16.2 Condemnation.

     A.  If the Premises shall be completely taken by exercise of eminent
domain, then this Lease shall terminate.  If any substantial part of the
Premises shall be taken by exercise of eminent domain or by action of any public
or other authority, then this Lease shall terminate at the election of Landlord
or Tenant, notice of which election shall be given to the other party within
sixty (60) days of such taking.  If Landlord shall not so elect, then in case of
such taking, and in case of any taking of less than a substantial part of the
Premises, a just proportion of said rent according to the nature and extent of
the taking shall be abated, unless the Landlord shall supply to Tenant
equivalent substitute space in the Building at no additional rent.  Landlord
reserves and accepts all rights to any awards of damages in connection with the
Premises and the Building and the leasehold hereby created, accrued or
subsequently accruing by reason of anything lawfully done in pursuance of any
public or other authority.  Tenant hereby releases and assigns to Landlord all
of Tenant's rights to such awards, and covenants to deliver such further
assignments and assurances thereof as Landlord may from time to time request,
hereby irrevocably designating and appointing Landlord as its attorney in fact
to execute and deliver in Tenant's name and behalf all such further assignments
thereof.  It is agreed and understood, however, that Landlord does not reserve
to itself, and Tenant does not assign to Landlord, any damages payable for

                                      -23-
<PAGE>   24
(i) moveable equipment installed by Tenant or anybody claiming under Tenant at
its own expense, or (ii) relocation expenses, but in each case only if and to
the extent that such damages are recoverable by Tenant from such authority in a
separate action and without reducing Landlord's award of damages.

     B.  Notwithstanding the above, Landlord may, in Landlord's sole    
discretion, repair and/or rebuild the Building in the event of either total
or partial taking.  Landlord will not be obligated to rebuild until the eminent
domain proceeds have been received and in the event such eminent domain
proceeds are insufficient to completely rebuild or restore the Premises,
Landlord, at Landlord's option, may provide the funds required to completely
rebuild or restore.  If Landlord's mortgagee applies the eminent domain proceeds
to the mortgage debt, Landlord shall have no obligation to rebuild, and Tenant
shall have the right to terminate by notice.

     C.  In the event that a taking of any portion of the Premises by the
exercise of eminent domain (a) materially adversely affects the ability of
Tenant to continue to conduct its business in the portion of the Premises not
taken; and (b) Landlord fails to give written notice within thirty (30) days of
its intention to restore the Premises; and (c) Landlord fails to restore the
Premises to a condition substantially suitable for their intended uses within
Ninety (90) days of such taking or fails to supply to Tenant equivalent
substitute space in the Building, Tenant may elect to terminate this Lease by
written notice to Landlord to be given no later than thirty (30) days after the
date last mentioned.  This right to terminate is an addition to Tenant's rights
to terminate under Paragraph 16.2.A. and Paragraph 16.2.B.

                            ARTICLE XVII: SURRENDER

     Upon the expiration or earlier termination of this Lease for any reason,
Tenant will at once surrender and deliver the Premises, together with all
improvements thereon, to Landlord in good condition and repair, reasonable wear
and tear excepted.  Reasonable wear and tear excludes:  tears and cuts in floor
coverings:  excessive wear of floor coverings because of Tenant's negligence or
failure to use desk and chair pads or otherwise; holes in walls and doors; and
damaged ceiling tiles because of installation of phone lines, computer lines, or
otherwise. All alterations, additions, improvements and partitions (except
Tenant's moveable trade fixtures, Clean Room equipment or furnishings, and clean
room HVAC system, and signs belonging to Tenant) erected or installed by Tenant
shall remain upon the Premises and will become the property of Landlord as of
the date of such expiration or earlier termination, unless

                                      -24-
<PAGE>   25
Landlord gives Tenant notice prior to expiration or earlier termination that
all such improvements must be removed, in which case Tenant, at its expense,
shall forthwith remove such improvements and restore the Premises to their
original condition by the date of expiration or earlier termination of this
Lease.  Tenant shall remove its moveable fixtures and signs and shall repair
all damage to the Premises caused by such removal.  Tenant's failure to remove
all or part of Tenant's trade fixtures and signs upon expiration or earlier
termination shall be deemed  an abandonment to Landlord of such trade fixtures
and signs and, if Landlord elects to remove all or any part of said fixtures
and signs, the cost of such removal, including repairing any damage to the
Premises caused by such removal, shall be paid by Tenant.  If installed by
Tenant (not Landlord), all telephone systems, fire alarm systems, burglar alarm
systems and any other security systems affixed to the Premises, upon the
termination of this Lease, may be removed by Tenant, provided that Tenant
repairs the Premises and replaces same to its condition prior to installation
of same, at Tenant's sole cost and expense.

                         ARTICLE XVIII:  HOLDING OVER


        18.1  Any holding over by Tenant of the Premises after the expiration
or earlier termination of this Lease will operate and be construed to be a
tenancy from month to month only at a monthly rental of One Hundred Fifty
Percent (150%) of the last monthly base rental plus all other Additional Rent
payable hereunder, and upon the terms hereof applicable to month-to-month
tenancy.

        18.2  Nothing contained in this section is to be construed to give
Tenant the right to hold over at any time and Landlord may exercise any and all
remedies at law or in equity to recover possession of the Premises and damages
resulting from any such holding over.

                            ARTICLE XIX:  DEFAULT


        The occurrence of any one or more of the following events ("Events of
Default") will constitute a default hereunder:

        A.  Tenant vacates or abandons the Premises.

        B.  Tenant defaults in any payment due hereunder and such default
continues for ten (10) days after the due date hereof.

        C.  Tenant fails to observe or perform any of the covenants,
conditions or provisions of this Lease to be observed or performed by Tenant
other than non-payment of sums due hereunder,

                                     -25-
<PAGE>   26
and Tenant fails to cure such default or diligently pursue such cure within
thirty (30) days after receipt of notice of said default.

     D.  Tenant petitions to be, or is declared bankrupt, or insolvent according
to law, or if a receiver be appointed for Tenant, or for all or a substantial
portion of its property, or if an assignment for the benefit of creditors is
made by Tenant and in the event of a non-voluntary action, Tenant fails to
obtain dismissal of said Assignment or petition within thirty (30) days of
receipt of notice of same.


                             ARTICLE XX:  REMEDIES

     20.1  Right to Terminate.

     If an Event of Default shall have occurred, Landlord shall have the right
at its election, then or at any time thereafter, to give Tenant written notice
of Landlord's election to terminate this Lease on a date specified in such
notice. Upon the giving of such notice, this Lease and the estate hereby granted
shall expire and terminate on such date as fully and completely and with the
same effect as if such date were the date hereinbefore fixed for the expiration
of the Term, and all rights of Tenant hereunder shall expire and terminate, but
Tenant shall remain liable as hereinafter provided.

     20.2  Right of Re-Entry.

If any Event of Default shall have occurred, Landlord shall have the    
immediate right, whether or not this Lease shall have been terminated pursuant
to Section 20.1, to peaceably re-enter and repossess the Premises or any part
thereof in the name of the whole and repossess the same as of its former estate
by peaceful summary proceedings, peaceful ejectment or otherwise and the right
to remove all persons and property therefrom.  Landlord shall be under no
liability for or by reason of any such entry, repossession or removal.  No such
re-entry or taking of possession of the Premises by Landlord shall be deemed to
waive or prejudice any remedies provided to Landlord hereunder, nor be
construed as an election on Landlord's part to terminate this Lease unless a
written notice of such election be given to Tenant pursuant to Section 20.1 or
unless the termination of this Lease be decreed by a court of competent
jurisdiction. Said right of re-entry shall be subject to Article XXVIII hereof.

     20.3  Right to Relet.

     At any time or from time to time after the repossession of the Premises or
any part thereof pursuant to Section 20.2, whether or not this Lease shall have
been terminated pursuant to

                                      -26-
<PAGE>   27
Section 20.2, Landlord shall use reasonable efforts to relet the Premises.
Landlord may let the Premises or any part thereof for the account of Tenant, in
the name of Tenant or Landlord or otherwise, without notice to Tenant, for such
term or terms (which may be greater or less than the period which would
otherwise have constituted the balance of the Term) and on such conditions
(which may include concessions or free rent) and for such uses as Landlord, in
its reasonable discretion, may determine, and Landlord may collect and receive
any rents payable by reason of such reletting.  Landlord shall use reasonable
efforts to let same as then fair market value, and Tenant shall indemnify
Landlord for the costs of said reasonable efforts as per Paragraph 20.5.

        20.4  Tenant to Remain Liable.

        No expiration or termination of this Lease pursuant to Section 20.1, by
operation of law or otherwise, and no repossession of the Premises or any part
thereof pursuant to Section 20.2 or otherwise, and no reletting of the Premises
or any part thereof pursuant to Section 20.3, shall relieve Tenant of its
liabilities and obligations hereunder, all of which shall survive such
expiration, termination, repossession or reletting.  Tenant shall be entitled
to credit for any and all amounts received by Landlord as a result of such
reletting.

        20.5  Current Damages.

        In the event of any expiration or termination of this Lease or
repossession of the Premises or any part thereof by reason of the occurrence of
an Event of Default, Tenant will pay to Landlord the Base Rent, Additional
Rent and other sums required to be paid by Tenant for the period to and 
including the date of such expiration, termination or repossession; and
thereafter, until the end of what would have been the Term in the absence of
such expiration, termination or repossession, and whether or not the Premises
or any part thereof shall have been relet, Tenant shall be liable to Landlord
to Landlord for, and shall pay to Landlord, as liquidated and agreed current
damages, the Base Rent, Additional Rent and other sums which would be payable
under this Lease by Tenant in the absence of such expiration, termination or
repossession, less the net proceeds, if any, of any reletting effected for the
account of Tenant pursuant to Section 20.3, after deducting from such proceeds
all of Landlord's expenses reasonably incurred in connection with such
reletting (including, without limitation, all repossession costs, brokerage and
management commissions, legal expenses, attorney's fees, repairs, alterations
or additions in or to the Premises that may be necessary.  Tenant will pay such
current damages on the days on which Base Rent would    have been payable under
this Lease in the absence of such expiration, termination or repossession, and

                                      -27-
<PAGE>   28
Landlord shall be entitled to recover the same from Tenant on each such day.

     20.6  Final Damages.

     At any time after any such expiration or termination of this Lease or
repossession of the Premises or any part thereof by reason of the occurrence of
an event of default, whether or not Landlord shall have collected any current
damages pursuant to Section 20.5.  Landlord shall be entitled to recover from   
Tenant, and Tenant will pay to Landlord on demand, as and for liquidated and
agreed final damages for Tenant's default and in lieu of all current damages
beyond the date of such demand (it being agreed that it would be impracticable
or extremely difficult to fix the actual damages), an amount equal to the
excess, if any, of (a) the Base Rent, Additional Rent and other sums which
would be payable under this Lease from the date of such demand (or, if it be
earlier, the date to which Tenant shall have satisfied in full its obligations
under Section 20.5 to pay current damages) for what would be the then unexpired
Term in the absence of such expiration, termination or repossession (assuming
for purposes hereof that Tenant's proportionate Share of Taxes and Insurance
are 120% of the payments required for the immediately preceding calendar year,
and the CPI shall increase by three percent (3%) each calendar year remaining
in the Term), over (b) the then net rental value of the Premises for the same
period.  Rental value shall be established by reference to the terms and
conditions upon which Landlord relets the Premises if such reletting is
accomplished within a reasonable period of time after such expiration,
termination or repossession, and otherwise established on the basis of
Landlord's reasonable estimates and assumptions of  fact regarding market and
other relevant circumstances.  If any statute or rule of law shall validly
limit the amount of such liquidated final damages to less than the amount above
agreed upon, Landlord shall be entitled to the maximum amount allowable under
such statue or rule of law.

     20.7  Damages and Proceedings.

     Nothing herein contained shall limit or prejudice the right of Landlord to
prove for and obtain in proceedings under any federal or state law relating to
bankruptcy, insolvency, reorganization, or arrangement, in an amount equal to
the maximum allowed by any statute or rule of law in effect at the time when,
and governing the proceedings in which, the damages are to be proved, whether or
not the amount be greater than the amount of loss or damage referred to above.

     20.8  Landlord's Right to Cure.

     Landlord may, but shall not be obligated to, cure any default by Tenant at
any time, and whenever Landlord so elects,

                                     -28-
                



<PAGE>   29
all costs and expenses paid or incurred by Landlord in curing such default,
including without limitation reasonable attorney's fees, shall be deemed
Additional Rent due within thirty (30) days of Tenant's receipt of the demand
with interest as provided in Section 3.6.  Any such cure shall not be deemed to
waive such default or otherwise affect any of the Landlord's rights due to such
default.

                          ARTICLE XXI: ATTORNEYS' FEES

If, on account of any breach or default by Tenant in Tenant's obligations
under the terms and conditions of this Lease, it becomes necessary or
appropriate for Landlord to employ or consult with an attorney or attorneys
concerning, or to enforce or defend, any of the Landlord's right or remedies
hereunder, Tenant agrees to pay all reasonable attorneys' fees so incurred.

                            ARTICLE XXII: NO WAIVER

     The waiver by Landlord of any breach of any term, covenant or condition
herein contained will not be deemed to be a waiver of such term, covenant or
condition for any subsequent breach of the same or any other term, covenant or
condition herein contained. The acceptance by Landlord of any payment of rent
or other charges hereunder, after the termination of this Lease by Landlord
shall not be deemed to restore this Lease or Tenant's right to possession
hereunder, but will be construed as a payment on account of damages due from
Tenant to Landlord. No remedy hereunder shall be deemed exclusive, but shall be
cumulative with all other remedies at law or equity.

                             ARTICLE XXIII: BROKER

     Tenant warrants that it has had no dealings with any broker or agent in
connection with this Lease other than Mark A. St. Jean of ACS Development

                           ARTICLE XXV:  MORTGAGES
25.1  Subordination.

        Tenant accepts this Lease subject and subordinate to any mortgage(s)
and/or deed(s) of trust now or at any time hereafter constituting a lien or
charge upon the Premises provided however that if the mortgagee, trustee or
holder of any such mortgage or deed of trust elects to have Tenant's interest
in this Lease be superior to any such instrument, then by notice to Tenant from
such mortgagee, trustee or holder, this Lease will be deemed superior to such
lien, whether this Lease is executed before or after such mortgage or deed of
trust.  Tenant will at any time hereafter on demand execute any instruments,
which may be required by any mortgagee for the purposes of subjecting and
subordinating this Lease to the lien of any such mortgage.  Tenant will give
notice to any mortgagee whenever notice is given to Landlord by Tenant
hereunder and no such notice to the Landlord will be effective unless also
given to any mortgagee.  In the event any proceedings are brought for
foreclosure or in the event of the exercise of the power of sale under any
mortgage or deed of trust made by Landlord covering the Premises, or in
the event any mortgagee obtains possession of the Premises by deed in lieu of
foreclosure, or in any other similar matter, the Tenant, at the request of any
such mortgagee or purchaser upon any such foreclosure or sale, will attorn to
the mortgagee or the purchaser of the Premises, and recognize said mortgagee or
purchaser as the Landlord under this Lease.  Tenant will, at the request of the
Landlord, execute a document, in form proper for recording such agreement to
attorn.  (See Exhibit D - "Example of Typical Subordination and Attornment
Agreement")

        Tenant may at Tenant's costs and expense record notice of the Lease in
the Registry of Deeds.  Landlord shall execute all documents reasonably
requested by Tenant in order to evidence this Lease and/or accomplish recording
of notice of same.

25.2  Notice to Mortgagee.

        In the event of any default on the part of Landlord, Tenant will give
notice by registered or certified mail to any beneficiary of a deed of trust or
mortgagee of a mortgage covering the Premises whose address shall have been
furnished it, and shall offer such beneficiary or mortgagee a reasonable
opportunity to cure the default, including time to obtain possession of the
Premises by power of sale or a judicial foreclosure, if such should prove
necessary to effect a cure.

25.3  Request by Mortgagee.

        In the event that the holder of any mortgage or prospective mortgage on
the Premises shall request any modification of any of
<PAGE>   31
the provisions of this Lease not having a material adverse effect on Tenant's
rights, Tenant agrees that Tenant will enter into a written agreement in
recordable form with such holder or prospective holder, which shall effect such
modification and shall provide that such modification shall become effective and
binding upon Tenant  and shall have the same force as an amendment to this Lease
in the event of a foreclosure or other similar action taken by such holder or
prospective holder.  A provision directly relating to the rents payable
hereunder, the duration of time hereof, the size, use, or location of the
Premises shall be deemed a provision having a material adverse effect on
Tenant's rights.

25.4 Assignment of Rights.

     With respect to any assignment by Landlord of Landlord's interest in this
Lease, or the rents payable hereunder, conditional in nature or otherwise, which
assignment is made to the holder of any mortgage on the Premises, the Building
or the Property, Tenant agrees that the execution thereof by Landlord, and the
acceptance thereof by the holder of such mortgage, shall never be deemed an
assumption by such holder of any of the obligations of Landlord hereunder,
unless such holder shall, by written notice sent to Tenant, specifically elect,
or unless such holder shall foreclose the mortgage, take possession of the
Premises, and agree in writing to so assume Landlord's obligations.

                             ARTICLE XXVI: NOTICES

     Any and all notices, demands, consents or approvals required hereunder
shall be given in writing in accordance with this Section.  Any notice from
Landlord to Tenant shall be deemed duly served, if left at the premises
addressed to Tenant or mailed to Tenant at the address listed herein by
reputable overnight courier, or by registered or certified mail, return receipt
requested, postage prepaid.  Any notice from tenant to Landlord shall be deemed
duly served, if mailed to Landlord by reputable overnight courier, or by
registered or certified mail, return receipt requested, postage prepaid,
addressed to Landlord at the address listed herein or at such address as
Landlord may from time to time designate.  All notices shall be deemed
sufficiently served or given for all purposes hereunder the earlier of (i)
receipt of such notice or (ii) two (2) business days after such notice shall be
deposited in any post office or branch post office regularly maintained by the
United States Government.

        6.  Landlord hereby authorizes Tenant to rely on any written notice or
demand received from Mortgagee to make rent and other payments, to which
Landlord may be entitled, to Mortgagee instead of Landlord whenever so demanded
by Mortgagee, whether or not the Mortgage shall have been foreclosed.

        7.  Tenant agrees that in the event Mortgagee shall succeed to the
rights of Landlord as landlord under the Lease, then Tenant shall look solely

of any successors and assigns of Mortgagee.

foreclosing the said Mortgage.  Mortgagee may assign and transfer its interest

It is understood and agreed by all parties hereto that upon making such
assignment, Mortgagee shall be automatically released of all obligations under
this Agreement and that by acceptance of such assignment, Assignee shall
thereby assume all obligations of Mortgagee hereunder.

     9.  This Agreement may be executed in three (3) or more counterparts by one
or more of the parties hereto and each such counterpart shall be deemed to be an
original and shall have the same force and effect as an original, and all
such counterparts in the aggregate shall constitute but one and the same
instrument.

        IN WITNESS WHEREOF, each of the parties hereto have hereunto set their
hands and seals, as of the day and year first above written.
