                                     PART I

Item 1.    Description of Business
- - ----------------------------------
Overview

           Medical Sterilization, Inc. ("MSI" or the "Company") provides
off-site reprocessing and sterilization of the Company's standard containerized
reprocessable sterilized surgical instrument sets as well as certain other items
requiring sterilization for healthcare providers such as hospitals and
ambulatory surgi-centers. MSI also provides contract steam and radiation
sterilization services for manufacturers of disposable medical products such as
bandages, sponges, tracheotomy kits, surgical gloves and laboratory ware. In
addition, the Company utilizes its electron beam radiation accelerator to
process various industrial products and to perform certain modifications to
those products.

           The Company provides its off-site reprocessing and sterilization
services and pre-sterilized reprocessable instrument sets to hospitals and
ambulatory surgi-centers within a radius of 75 miles of its Syosset, New York
facility. As of December 31, 1995, MSI had 22 long-term and 6 short-term
contracts with healthcare providers in its area of operations and estimates that
there are approximately 250 hospitals within this area. The Company provides its
contract steam and radiation sterilization services to manufacturers of
disposable medical products within a 300 mile radius of its Syosset facility.
The Company currently provides sterilization services for approximately 30
medical products manufacturers such as Busse Hospital Disposables, Elkay
Products, Inc. and Hermitage Hospital Supply Corp., and estimates that there are
approximately 200 such manufacturers in its operating area. MSI processes
industrial products for several industrial companies principally in the
Northeastern United States and processes polytetrafluoroethylene ("PTFE"), also
known as "Teflon" (a registered trademark of E.I. Dupont de Nemours & Co.),
solely for Precision Micron Powders, Inc., a distributor of processed PTFE owned
by Shamrock Technologies, Inc., and for Shamrock Technologies, Inc.

           The Company was founded in May 1982 as a New York corporation. Its
principal executive offices are located at 225 Underhill Boulevard, Syosset, New
York 11791, and its telephone number is (516) 496-8822.

           Statements in this Form 10-KSB which are not historical facts,
so-called "forward-looking statements," are made pursuant to the safe harbor
provisions of the Private Securities Litigation Reform Act of 1995. Investors
are cautioned that all forward-looking statements involve risks and
uncertainties, including those detailed herein and in the Company's other
filings with the Securities and Exchange Commission. See "Item 6. Management's
Discussion and Analysis of Financial Condition and Results of Operations-Certain
Factors That May Affect Future Results."

Sterilization Services for Healthcare Providers

           MSI provides off-site cleaning, decontamination and sterilization
processing of the Company's standard containerized reprocessable sterilized
surgical instrument sets ("Instrument Sets") as well as certain other items
requiring sterilization ("Sterilizable Items") for healthcare providers such as
hospitals and ambulatory surgi-centers within a radius of 75 miles of its
Syosset, New York facility. As of December 31, 1995, the Company had 28
sterilization service contracts with hospitals and ambulatory surgi-centers. The
Company estimates that there are approximately 250 such healthcare providers in
its operating area.

           Sterilizable Items consist of surgical instruments, utensils,
surgical gowns and wraps and other items used in healthcare facilities which
require sterilization. Instrument Sets are pre-packaged, sterilized,
reprocessable instrument sets, each of which is a complete set of instruments
necessary for a given medical procedure. The Company has designed approximately
85 different Instrument Sets for operating room procedures and labor and
delivery, including gall bladder, tonsillectomy and adenoidectomy, open heart,
vascular, orthopedic, endoscopy, cesarean sections, newborn delivery,
hysterectomy and dilation and curettage. MSI packages its Instrument Sets in
rigid containers with filters and seals, thereby maintaining sterile integrity
without the risk of tearing and pinholes which occur in more traditional
wrappers. The Instrument Sets aid in the organization of the instruments for
ease of use and provide for better instrument accountability once the procedure
is completed. Once an Instrument Set has been utilized, it is returned to the
Company for cleaning, sterilization and repackaging.

           The Company's services are designed to replace or supplement the
existing in-house sterilization facilities of healthcare providers. Many
hospitals have older, less efficient sterilization facilities, staff their
facilities with nurses whose skills could be more effectively used elsewhere and
underutilize their sterilization facilities by operating their equipment only
once per day. Because of the relatively low volume of sterilization activities
undertaken at many of these facilities, worker productivity may not be as high
as in other areas of the healthcare organization, causing concern for
administrators. In addition, as hospitals continue to evaluate ways in which to
better utilize their available space, many hospitals are seeking to replace
their in-house sterilization facilities with profit generating centers such as
operating rooms. Many hospitals are also looking for ways in which to improve
operating room efficiency by eliminating the sterilization processing delays and
shortages sometimes experienced with their in-house sterilization facilities.

           By utilizing state of the art, industrial size equipment, modern
sterilization technology, less expensive labor, and handling larger volumes, the
Company believes that it offers a cost-effective, high quality alternative to
in-house sterilization facilities. The Company processes Instrument Sets and
Sterilizable Items for numerous customers and has installed modern, industrial
size sterilization equipment at its Syosset facility, including ultrasonic
cleaners, a tunnel washer and a 300 cubic foot steam sterilizer. The Company is
in the process of installing an additional tunnel washer and another 300 cubic
foot steam sterilizer.



                                       3
<PAGE>

           The Company believes that it offers better sterility assurance levels
than those maintained at many hospitals. In order to comply with the infection
control requirements of the Joint Commission on Accreditation of Healthcare
Organizations ("JCAHO"), the Center for Disease Control, the Association for
Advancement of Medical Instrumentation ("AAMI"), the Association of Operating
Room Nurses ("AORN"), the policies and procedures of each respective hospital as
well as the requirements of Federal, state and local government agencies, the
Company has established rigorous testing measures and procedures, such as
sterilization process monitors (including temperature and pressure recording),
chemical indicators and bacteriological spore and culture testing. The Company
is a registered contract sterilization facility with the U.S. Food and Drug
Administration ("FDA"), even though neither the Company's activities in this
area nor hospital sterilization facilities are required to be so registered. See
"-Government Regulation."

Contract Sterilization of Disposable Medical Products

           MSI provides contract steam and radiation sterilization services to
manufacturers of disposable medical products. The Company sterilizes disposable
medical products such as adhesive and gauze bandages, lap sponges, absorbent
cotton balls, tracheotomy kits, trauma dressings, operating room drapes,
surgical gloves, in vitro diagnostic kits and laboratory ware, such as pipettes,
petri dishes, flasks, roller bottles and tissue culture wells. As of December
31, 1995, the Company's customers in this area included 30 disposable medical
products manufacturers within a 300 mile radius of its Syosset, New York
facility. MSI estimates that there are approximately 200 disposable medical
products manufacturers operating in this geographic area.

           The Company's contract sterilization services are utilized by
manufacturers of disposable medical products which do not have in-house
sterilization capabilities or which have limited in-house capacity and utilize
the Company's services to handle overflow. The Company's services are also used
by manufacturers which require electron beam radiation sterilization either
because the nature of the product requires electron beam radiation treatment to
achieve acceptable levels of sterilization or because for certain products
electron beam radiation sterilization can be more cost-effective than other
methods. The Company believes that approximately 10% of all disposable medical
products and devices are sterilized using electron beam radiation. To meet this
need for contract sterilization services, MSI has established a radiation
facility featuring a 4.5 million electron volt, 150 kilowatt accelerator which
provides either electron or x-ray radiation.

           Although the Company provides sterilization services for
approximately 30 manufacturers of disposable medical products and is sterilizing
products on a daily basis, the Company has experienced reduced orders from
certain large customers over the preceding three years and has a significant
amount of available capacity in its contract sterilization business. The
Company's Board of Directors has determined that it is in the best interests of
the Company's shareholders that the Company focus on its core Instrument Set
sterilization processing business. The Company is evaluating opportunities to
maximize the value of its electron-beam related businesses, including its
contract sterilization of disposable medical products unit and its 



                                       4
<PAGE>

radiation processing of industrial products unit either through sale, joint 
venture or other commercial means. See "Management's Discussion and Analysis of
Results of Operations and Financial Condition."

Radiation Processing of Industrial Products

           MSI performs radiation processing services for a number of industrial
products manufacturers. The Company's electron beam accelerator can be used to
link chemically a long string of molecules of polyethylene and
polyvinylchloride, to treat crude rubber to achieve bonding and hardening and to
link undivided chemical compounds into a larger chemical entity. As of December
31, 1995, the Company was processing industrial products for several industrial
companies principally in the Northeastern United States, which products included
fabricated plastic objects, gaskets, tubing and plastic sheet and film. As part
of its radiation processing services, the Company can also cross-link the
insulation on small gauge wire.

           The Company's primary radiation processing activity is the
irradiation of polytetrafluoroethylene ("PTFE"), which is also known as "Teflon"
(a registered trademark of E.I. Dupont de Nemours & Co). Once processed, the
PTFE can be ground into very small particles for use primarily as an additive
for printing inks and as a lubricant. The Company processes PTFE for Precision
Micron Powders, Inc. ("Precision"), a PTFE distributor owned by Shamrock
Technologies, Inc. ("Shamrock"), and for Shamrock. The Company processes PTFE
for Precision and Shamrock pursuant to a Toll Processing Agreement, as amended,
entered into in connection with the settlement of a lawsuit brought against the
Company by Shamrock. See "Item 3. Legal Proceedings." Pursuant to the Toll
Processing Agreement, as amended, MSI will process PTFE only for Precision and
Shamrock, and Precision and Shamrock agree to use certain minimum levels of
processing services through June 30, 1997 at prices which will result in a gross
profit to the Company for providing these services. The Company anticipates that
the amended Toll Processing Agreement will result in the purchase by Precision
and Shamrock of approximately $4.2 million of PTFE processing services for the
period of January 1, 1996 through June 30, 1997 if the Toll Processing Agreement
is performed in accordance with its terms. The term of the Toll Processing
Agreement may be extended at Shamrock's option in three month increments until
December 31, 1997, after which time MSI must cease processing PTFE, unless
otherwise agreed by Shamrock.

           The Company's Board of Directors has determined that it is in the
best interests of the Company's shareholders that the Company focus on its core
Instrument Set sterilization processing business. The Company is evaluating
opportunities to maximize the value of its electron-beam related businesses,
including its contract sterilization of disposable medical products unit and its
radiation processing of industrial products unit either through sale, joint
venture or other commercial means. See "Management's Discussion and Analysis of
Results of Operations and Financial Condition."



                                       5

Competition

           The Company's principal competition with respect to its sterilization
services for healthcare providers comes from the in-house sterilization
facilities of hospitals and ambulatory surgi-centers. Most hospitals have an
in-house sterilization capability and many have invested significant capital in
their sterilization facilities. Also, the in-house sterilization facility staff
may be committed to maintaining the facility and its current staffing levels. As
a result, healthcare providers may be reluctant to shift their sterilization
activities from in-house to an off-site contractor. The Company also understands
that Baxter V. Mueller ("Baxter"), a division of Baxter Health Care Corporation,
a company with substantially greater financial and other resources than MSI, has
established Offsite Instrument and Gown Reprocessing and Sterilization Service
Centers in Chicago, Illinois; Houston, Texas; Detroit, Michigan; Tampa, Florida;
and Baltimore, Maryland. Although the Company does not directly compete with
Baxter, there can be no assurance that Baxter will not open an Offsite
Instrument and Gown Reprocessing and Sterilization Center in the Company's
service territory. If such a center were opened in the Company's service
territory, the Company's business, results of operations and financial condition
could be materially adversely affected. In addition, the Company is aware of an
emerging trend for some hospitals to outsource their endoscopy decontamination
processing to mobile endoscopy reprocessors who provide limited on-site
decontamination services to the hospital, which then will utilize its in-house
facility for sterilization. The Company has identified endoscopy decontamination
and sterilization as a target market for its services. To the extent the Company
enters into this field, it will face competition from these mobile endoscopy
reprocessing service providers. There can be no assurance that the Company will
be able to penetrate the market for endoscopy processing and sterilization
services, to achieve significant market share or to compete effectively with
mobile endoscopy reprocessing service providers.

           The market for contract sterilization of disposable medical products
services is highly competitive. There are a number of entities, most of which
have significantly greater financial and other resources than the Company, which
offer contract sterilization services. The Company's major competitors in this
area include Isomedix Inc., E-Beam Services, Inc. and Ethox Corp. The Company
also competes with in-house sterilization departments of disposable medical
products manufacturers. There are a number of companies, many of which have
significantly greater financial and other resources than the Company, with
sterilization capabilities, primarily Ethylene Oxide ("EtO"), radiation and
steam sterilization, as well as decontamination and packaging capabilities,
which could enter into the healthcare provider field or the disposable medical
products field in the future.

           In the industrial products radiation processing area, the Company
competes with a number of competitors, including Isomedix Inc. and E-Beam
Services, Inc.. Most of these companies have significantly greater financial and
other resources than the Company. In the year ended December 31, 1995,
substantially all of the Company's revenues from radiation processing of
industrial products services were derived from the provision of PTFE processing
services for Precision and Shamrock. Pursuant to the amended Toll Processing
Agreement with Shamrock, all of the Company's PTFE processing during 1995 was,
and in the future will be, performed for Precision and Shamrock at established
minimum production levels and the Company is not 




                                       6
<PAGE>

permitted to process PTFE for any other party. As a result, the Company does not
currently face competition with respect to its PTFE processing services.

           MSI believes that the principal bases of competition include price,
quality, reputation and rapid turnaround. The Company believes that it competes
favorably with respect to these factors, although there can be no assurance that
it will be able to continue to do so. The ability of the Company to compete
successfully in the future will depend on factors both within and outside its
control, including the Company's ability to modernize and upgrade its
technology, to improve and modernize its sterilization processes, to respond to
changing market conditions and the activities of its competitors, to control
costs, to grow its customer base both within its existing geographic area and
nationally in a manner which permits the allocation of fixed costs over a
broader revenue base, and general market and economic conditions. The Company's
ability to compete will also depend, in significant part, upon the Company's
ability to convince hospitals to shift their sterilization activities from
in-house to the Company's off-site facilities and to penetrate the marketplace
for endoscopy decontamination and processing services. There can be no assurance
that the Company will be able to compete successfully with respect to these
factors in the future or that present competitors or future entrants will not
successfully compete with the Company in the future, any of which could have a
material adverse effect on the Company's business, results of operations or
financial condition.

Customers

           The Company sells its sterilization services to healthcare providers
such as hospitals and ambulatory surgi-centers within a 75 mile radius of its
Syosset facility. As of December 31, 1995, the Company provided Instrument Sets
and sterilization services for Sterilizable Items pursuant to 28 sterilization
services contracts with hospitals and ambulatory surgi-centers. With respect to
contract sterilization services for disposable medical products manufacturers,
as of December 31, 1995, the Company provided contract sterilization services to
30 disposable medical products manufacturers within a 300 mile radius of its
facility in Syosset. The Company performs its PTFE processing services for
Precision and Shamrock and processes other industrial products for other
manufacturers. As of December 31, 1995, the Company was processing industrial
products for several industrial companies principally in the Northeastern United
States. For the fiscal year ended December 31, 1995, sales to Precision and
Shamrock accounted for substantially all of the Company's revenues from
industrial product radiation processing services and 30% of the Company's total
revenues. No other single customer accounted for 10% or more of the Company's
total revenues for the fiscal year ended December 31, 1995. The loss of any one
or more significant customers could have a material adverse effect on the
Company's business, results of operations and financial condition.

Suppliers

           The Company purchases from surgical instrument manufacturers the
surgical instruments included in Instrument Sets that are provided to hospitals
and ambulatory surgi-centers. Pursuant to a sales and marketing agreement
recently entered into with Pilling Weck, a national surgical instrument
manufacturer and a division of Teleflex Incorporated, the Company 



                                       7
<PAGE>

has agreed to purchase substantially all of its surgical instrument requirements
from Pilling Weck, and Pilling Weck has agreed to supply surgical instruments to
the Company as well as to be the exclusive sales and marketing agent for MSI in
the United States. See "-Sales and Marketing." Pursuant to this agreement, the
Company will receive certain volume pricing discounts and the Company will
utilize Pilling Weck supplied instruments in its Instrument Sets unless a
particular customer requires the use of another instrument vendor. The Company
believes that surgical instruments are readily available from other suppliers at
market prices should Pilling Weck for any reason be unable to satisfy the
Company's instrument needs in full.

Sales and Marketing

           MSI's sales and marketing strategy is to grow existing accounts by
service expansion: for example, if the Company is serving the labor and delivery
department of a hospital it will attempt to leverage its services into the
general operating room of the hospital after a period of successful product
performance in the labor and delivery area. The Company also intends to expand
its portfolio of reprocessing services to include new service offerings such as
endoscopy procedure specific Instrument Sets. The Company's sales and marketing
efforts are coordinated by two dedicated in-house sales professionals who are
supported by a third sales coordinator who works with the hospitals to determine
the proper configuration of the Instrument Sets to be provided to each hospital.
In addition, the Company has recently entered into a sales and marketing
agreement with Pilling Weck which provides, among other things, for Pilling Weck
to represent and sell MSI's decontamination, reprocessing and sterilization
services to customers in select highly populated urban centers in exchange for
specified commissions. Pursuant to the sales and marketing agreement, which has
a three-year term ending January 5, 1999 unless extended or earlier terminated
in accordance with its terms, Pilling Weck is providing to MSI the services of
its 10 Northeast sales representatives who are assisting the Company in
developing sales opportunities in the Northeast corridor.

Intellectual Property

           The Company does not rely on any patents for the conduct of its
business. The Company does rely upon the know-how of its employees and has
executed non-disclosure and non-competition agreements with its employees. The
Company relies in significant part upon its hospital tracking software which
allows the Company to monitor and control the levels of Sterilizable Items and
Instrument Sets on site with a given customer and to plan and control
sterilization activities. The Company's hospital tracking software was purchased
from its developer and the copyrights were assigned to the Company. Although the
Company believes that it has all necessary ownership and copyright rights in its
hospital tracking software and that this software does not infringe upon the
intellectual property rights of third parties, any determination to the contrary
could have a material adverse effect on the Company's business, results of
operations and financial condition.



                                       8
<PAGE>

Government Regulation

         The Company has obtained a license from the New York State Department
of Labor, Division of Safety and Health, Radiological Health Unit to operate its
radiation sterilization and processing facility. This license is currently in
force and the Company believes it is in material compliance with applicable laws
and regulations with respect to its radiation sterilization and processing
facility.

         The Company is registered with the Department of Health and Human
Services, Public Health Service of the FDA, and believes it is in material
compliance with the FDA compliance program with regard to the industrial
sterilization of medical devices. The Company complies with this program even
though, for these purposes, a hospital (and the Company, by extension) is not
considered to be a manufacturer of medical devices and is therefore not subject
to the FDA regulations.

         The Company believes that it is in material compliance with the
regulations of the Nassau County Department of Public Works with regard to the
disposition of effluents. The Company has a certificate to operate an ozone
emission source from the Nassau County Department of Health which enforces the
regulations of the New York State Department of Health. In July 1994, the New
York State Department of Environmental Conservation announced stringent
standards with regard to the emission of ozone . The Company is working with
State and County authorities on an established timeline to bring the Company
into compliance with these standards. MSI has hired consultants to measure the
emissions of ozone and, in conjunction with State and County authorities, to
design necessary pollution control equipment to meet these standards. The
Company estimates that the cost of equipment to bring the Company into
compliance with these standards will be approximately $300,000. If the Company
does not comply with these ozone emission standards it will not be able to
obtain a permit to operate its electron beam accelerator, resulting in a
significant reduction in revenues. With the exception of this potential
expenditure, the Company's cost of compliance with applicable environmental laws
and regulations has not been material. However, there can be no assurances that
changes in existing environmental laws or the enactment of new laws will not
require the Company to invest substantial amounts in pollution control
equipment. Any such changes, or any failure to comply with environmental laws
and regulations, could have a material adverse effect on the Company's business,
results of operation or financial condition. See "Item 3. Legal Proceedings."

         The Company is also subject to the requirements of the Occupational
Safety and Health Administration ("OSHA") and believes that it is in material
compliance with OSHA. The Company believes that it is in material compliance
with all other applicable federal, state and local rules and regulations
relating to the conduct of its business.

Employees

         As of December 31, 1995, the Company had 81 full-time and 20 part-time
employees. Management believes its relations with its employees are good. None
of its employees are covered by any collective bargaining agreement.

Item 2.     Description of Property
- - -----------------------------------

         The Company's headquarters, including its executive offices,
sterilization facility and radiation processing facility, occupy 103,000 square
feet of leased space in a building located at 225 Underhill Boulevard, Syosset,
New York. The Company originally entered into its headquarters lease on March 1,
1984. In February 1994, the Company and the Landlord amended the lease to extend
its term from March 1, 1994 to February 28, 1996, with an annual rent of
$432,000. On November 20, 1995, the Company executed a new lease for its
headquarters which provides for a term of March 1, 1996 through February 28,
2001 with an annual rent of $456,000 for the first three years and $504,000 for
the next two years.

         The Company believes that its facilities and equipment are in good
condition and are suitable for its operations as presently conducted and for its
foreseeable future operations. The Company currently believes that additional
facilities and equipment can be acquired if necessary, although there can be no
assurance that additional facilities and equipment will be available upon
reasonable or acceptable terms, if at all.

Item 3.    Legal Proceedings
- - ----------------------------

         The Company and Robert S. Luniewski, its former Senior Vice President,
were named as defendants in an action which was commenced on May 31, 1988 in the
United States District Court, Eastern District of New York, by Shamrock alleging
patent infringement, breach of an Employment Agreement, a Trade Secret Agreement
and fiduciary relationship as an officer of Shamrock. Shamrock was awarded
damages in the amount of $2,677,728.70 together with interest on the sum of
$2,057,294.30 at the rate of 1.5% above the prime rate from August 21, 1989.
Shamrock also obtained a permanent injunction as of September 3, 1989 against
the Company from processing PTFE by methods which allegedly infringed Shamrock's
patent and violated trade secrets. The Court of Appeals for the Federal Circuit
affirmed the award of damages. In November 1994, Shamrock and MSI entered into
agreements as a result of which the judgment, then in the amount of $3,751,600
including interest, was satisfied. In settlement, the Company paid $62,500 to
Shamrock; issued to Shamrock warrants to purchase 75,000 shares of the Company's
Common Stock at $2.00 per share; and issued to Shamrock 25,000 shares of the
Company's Common Stock. See Note 13 of Notes to Financial Statements.

         At the time of the settlement in November 1994, the Company and
Shamrock entered into the Toll Processing Agreement pursuant to which Shamrock
agreed to purchase from the Company $3.3 million of PTFE processing services
over a period of 18 months ending May, 1996 at prices which provided for a gross
profit to the Company. On November 1, 1995, the Toll Processing Agreement was
extended and modified. The extension covers a period of 18 months 



                                       10
<PAGE>

which commenced January 1, 1996 and ends on June 30, 1997, unless extended at
Shamrock's option for additional three month increments through December 31,
1997. Because the extension agreement was to commence on January 1, 1996, the
existing requirement for Shamrock to purchase $3.3 million of PTFE processing
services through May of 1996 was terminated as of December 31, 1995. For the
period from November 1994 through December 31, 1995, Shamrock had purchased
approximately $3,200,000 of PTFE processing services pursuant to the Toll
Processing Agreement. During the extension period the Company has agreed to
provide, and Shamrock has agreed to use, certain minimum levels of processing
services at prices which will result in a gross profit to the Company for
providing these services. If the extension agreement is performed in accordance
with its terms, the Company estimates that Shamrock and Precision will purchase
approximately $4.2 million of PTFE processing services from January 1, 1996
through June 30, 1997. The Company has agreed that it will not process PTFE for
any other entity during and after the termination of its agreement with
Shamrock.

         MSI gave to Shamrock as security a confession of judgment in the amount
of $1,250,000 to be entered only if any agreement listed in the Settlement
Agreement is rejected under the provisions of the Bankruptcy Code and only if a
proceeding is commenced in the future in which the Company is the bankrupt
party. The Confession of Judgment is limited to the earlier of the rejection of
an agreement by the Bankruptcy Court and 120 days after the termination of the
original Toll Processing Agreement on December 31, 1995.

         In addition, in July 1994 the New York State Department of
Environmental Conservation announced stringent standards with regard to the
emission of ozone. The Company is working with State and County authorities on
an established timeline to bring the Company into compliance with these
standards. The Company has hired consultants to measure the Company's ozone
emissions and, in conjunction with State and County authorities, to design
necessary pollution control equipment to meet these standards. The estimated
cost of such pollution control equipment is approximately $300,000. In the event
the Company does not install such pollution control equipment, it will not
obtain a permit to operate its electron beam accelerator, which would result in
a significant reduction in revenues and would have a material adverse effect on
the Company's business, results of operations and financial condition. See "Item
1. Description of Business-Government Regulation."

         No matters were submitted for a vote of security-holders during the

         The Company has never paid cash dividends with respect to its shares of
Common Stock. The Company currently intends to retain earnings, if any, for use
in its business and does not anticipate paying cash dividends on its shares of
Common Stock in the foreseeable future. The Company is required to pay dividends
in cash or in kind with respect to the outstanding shares of Series B
Convertible Preferred Stock. In addition, the Company's loan agreements, the
Financing Agreement with Rosenthal and Rosenthal, Inc. and the terms of the
Company's outstanding Series B Convertible Preferred Stock and the Series C
Convertible Preferred Stock prohibit the payment of dividends on the shares of
Common Stock. See Notes 6 and 8 of Notes to Financial Statements.

Item 6.    Management's Discussion and Analysis of Financial Condition and 
           Results of Operations
- - ---------------------------------------------------------------------------

Overview

         The Company had net income in the year ended December 31, 1995 of
approximately $192,000 as compared to approximately $52,000 for the year ended
December 31, 1994. The increase in net income of approximately $140,000 was due
primarily to a 17% increase in sales volume in the Company's sterilization
services for healthcare providers business in 1995 as compared to the Company's
sales volume in that business for 1994, partially offset by reduced sales volume
in the Company's radiation processing business and an increase in operating
expenses and selling, general and administrative expenses.

         The Company had net income in 1994 of approximately $52,000 as compared
to approximately $246,000 in 1993. The decrease was due primarily to reduced
sales volume in the Company's contract sterilization business as several
customers (Costar and American White Cross) reduced their business with the
Company. Even though sales in the Company's sterilization services for
healthcare providers and radiation processing businesses increased, they could
not offset the significant loss of volume in the contract sterilization
business. The profit in 1993 was primarily a result of the reversal of the
unapplied portion of the reserve for litigation loss the Company had accrued as
of December 31, 1992.

         For the fiscal year ended December 31, 1995, the Company's
sterilization services for healthcare providers, contract sterilization of
disposable medical products and radiation processing of industrial products
businesses accounted for approximately 53.7%, 15.3% and 31.0%, respectively, of
the Company's revenues, as compared with 49.2%, 15.4% and 35.4%, respectively,
for the fiscal year ended December 31, 1994. The Company's Board of Directors
has determined that it is in the best interests of the Company's shareholders
that the Company focus on its core Instrument Set sterilization processing
business. The Company is evaluating opportunities to maximize the value of its
electron-beam related businesses, including its contract sterilization of
disposable medical products unit and its radiation processing of industrial
products business unit either through sale, joint venture or other commercial
means.

         Price increases are governed by contract terms for sterilization
services to healthcare providers. These contracts have recognizable escalation
factors. The prices for sterilization of disposable medical products and the
processing of industrial products are determined by competition and market
conditions. Price increases normally will be reflected in increased revenues and
profits and a price decreases normally will result in decreased revenues and
profits.

         In November 1994, the Company satisfied an outstanding judgment against
it, entered into a two million dollar working capital line of credit with an
asset-based lender, restructured its bank financing and renegotiated the terms
of its existing preferred stock with its majority preferred shareholders See
Notes 6, 8, 9 and 13 of Notes to Financial Statements.


                                       13
<PAGE>

         In December 1995, the Company extended the term of its working capital
line of credit (which was due to expire in November 1996) to January 1997. All
other terms of the agreement were left the same. See Note 6 of Notes to
Financial Statements.

Results of Operations

1995 Compared with 1994
- - -----------------------

         Revenues. Revenues for the year ended December 31, 1995 increased
approximately 7% to approximately $8,772,000 from approximately $8,220,000 for
the year ended December 31, 1994. The increase in revenues was attributable to
an approximate $685,000 or 8% increase in total revenues related to the
Company's sterilization services to healthcare providers business and an
approximate $77,000 or 1% increase in total revenues related to the Company's
contract sterilization business, partially offset by an approximate $207,000 or
2% decrease in total revenues related to the Company's radiation processing of
industrial products business. The increase in total revenues related to the
Company's sterilization services to healthcare providers was attributable to
market penetration of new customers and expanded services to the Company's
existing customer base. The Company's sales strategy is to grow existing
accounts by service expansion: for example, if the Company is serving the labor
and delivery department of a hospital it will attempt to leverage its service
into the general operating room of the hospital after a period of successful
product performance in the original labor and delivery area. MSI also intends to
expand its portfolio of reprocessing services to include new service offerings
such as endoscopy procedure specific Instrument Sets. The decrease in radiation
processing revenues was primarily attributable to discounted prices given to its
largest customer. These price concessions, which are basically volume discounts,
were given to ensure a steady flow of production through its facility which
provides for a more consistent absorption of the Company's overhead.

         Gross Profit. Gross profit increased approximately $374,000 or 19% from
approximately $1,972,000 in the year ended December 31,1994 to approximately
$2,346,000 in the year ended December 31, 1995. Gross profit as a percentage of
revenues increased 2.8% from 23.9% in the year ended December 31, 1994 to 26.7%
in the year ended December 31, 1995. The increase in the Company's gross profit
was attributable to improved production efficiencies in the Company's plant. The
major components of these efficiencies were a reduction in labor as a percentage
of revenues, and a reduction of utilities as the Company made arrangements to
purchase the major portion of its electricity from the New York State Power
Authority at reduced rates.

         Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased by approximately $116,000 from approximately
$1,706,000 in the year ended December 31, 1994 to approximately $1,822,000 in
the year ended December 31, 1995. As a percentage of revenues, selling, general
and administrative expenses increased from 20.7% in the year ended December 31,
1994 to 20.8% in the year ended December 31, 1995. The major portion of the
increase resulted from the recruiting and eventual hiring of a new president of
the Company and the expenses related thereto, which was a non-recurring expense.
In most other 


                                       14
<PAGE>

areas of selling,  general and administrative  expenses, the Company experienced
virtually no increases.

         Interest Expense. Interest expense increased from approximately
$221,000 or 2.7% of revenues for the year ended December 31, 1994 to
approximately $335,000 or 3.8% of revenues for the year ended December 31, 1995.
This increase of $114,000 or 52% was the result of increased borrowing to
support the Company's growth and an increase in the Company's interest rate.

         Net Income. Net income increased from approximately $52,000 or 0.6% of
revenues in 1994 to approximately $192,000 or 2.2% of revenues in the year ended
December 31, 1995. This represented an increase of approximately $140,000 or
269% for the year ended December 31, 1995 compared to the year ended December
31, 1994. The increase in net income is basically attributable to the increased
sales volumes and gross margin increases partially offset by increases in
selling, general and administrative expenses and interest expense as the Company
continued to make investments in these areas.

         Net Income (Loss) Applicable to Common Shareholders. Net income (loss)
applicable to common shareholders for the year ended December 31, 1995 increased
to approximately $77,000 from a net loss of approximately ($126,000) for the
year ended December 31, 1994. This represented an increase of approximately
$203,000 for the year ended December 31, 1995 compared to the year ended
December 31, 1994. The increase was the result of the increase in net income
described above and the decrease in dividends on the Preferred Stock from
approximately $178,000 in the year ended December 31, 1994 to approximately
$114,000 in the year ended December 31, 1995. This decrease was the result of
the restructuring of the Company's Preferred Stock in the year ended December
31, 1994 which reduced the amount of Preferred Stock bearing dividends and also
reduced the dividend rate.

         Net Income (Loss) Per Share of Common Stock. Net income (loss) per
share of common stock for the year ended December 31, 1995 increased to $.02 per
share compared to a net loss per share of ($.04) for the year ended December 31,
1994. The increase was primarily attributable to the increased net income
applicable to common shareholders described above partially offset by an
increase in the weighted average number of common shares outstanding.

1994 Compared With 1993

         Net income for 1994 was approximately $52,000 compared to approximately
$246,000 in 1993. The net loss per share after adjustment for accrued dividends
on Preferred Stock was ($.04) for 1994 compared to net income per share of $.00
in 1993. The decrease in net income was primarily due to a significant decrease
in the Company's contract sterilization services which could not be totally
offset by modest growth in its sterilization services for healthcare
organizations and radiation processing of industrial products services.

         Revenues decreased to approximately $8,220,000 in 1994 from
approximately $8,476,000 in 1993. This decrease of approximately $256,000 or 3%
resulted principally from 


                                       15
<PAGE>

the loss of business  in the  Company's  contract  sterilization  of  disposable
medical products business.

         Operating expenses increased to approximately $6,248,000 in 1994 from
approximately $5,991,000 in 1993. This increase of approximately $257,000 or 4%
resulted primarily from increased costs for utilities, healthcare insurance and
raw materials.

         Selling, general and administrative expenses decreased in 1994 to
approximately $1,706,000 from approximately $2,003,000 in 1993. This decrease of
approximately $297,000 or 15% resulted primarily from reductions in litigation
expenses and from management's decision to limit expenses as much as possible in
this area in response to the ongoing negotiation of its patent infringement case
which was successfully completed in November 1994.

         Interest expense decreased to approximately $221,000 in 1994 from
approximately $236,000 in 1993. This decrease of approximately $15,000 or 6% was
due to a decrease in borrowing as the Company curtailed its instrument purchases
in response to the patent infringement lawsuit.

Liquidity and Capital Resources

         Current assets have increased approximately $205,000 to approximately
$2,837,000 at December 31, 1995 from approximately $2,632,000 at December 31,
1994. The increase was primarily attributable to an approximate $50,000 increase
in accounts receivable and an approximate $61,000 increase in inventory. The
Company had working capital of approximately $1,607,000 at December 31, 1995
compared to working capital of approximately $1,149,000 at December 31, 1994.
The Company's current ratio at December 31, 1995 was 2.31 to 1 compared to a
current ratio of 1.77 to 1 at December 31, 1994. The improvement in the
Company's working capital and current ratio at December 31, 1995 compared to
December 31, 1994 was primarily the result of the increases in accounts
receivable and inventory and the reduction of short-term debt through the use of
the Company's line of credit which is classified as long-term. In November 1995,
the Company extended its line of credit (which was to expire in November of
1996) to January 31, 1997. The Company currently plans to expand its business
both geographically and by increasing its portfolio of reprocessing services to
include new service offerings such as endoscopy procedures Instrument Sets. In
addition, the Company will be required to expend approximately $300,000 on
pollution control equipment in the future (see "Item 1. Business-Government
Regulation"). The Company believes that the anticipated future cash flow from
operations, along with its cash on hand and available funds under its working
capital line of credit will be sufficient to meet working capital requirements
during 1996. There can be no assurance, however, that the Company will not
require additional working capital and, if it does require such capital, that
such capital will be available to the Company on acceptable terms, if at all.

         As of December 31, 1994, the Company had working capital of
approximately $1,149,000 as compared to approximately $864,000 in 1993. This
change in the Company's working capital was due primarily to a complete
restructuring of the Company's financial 


                                       16
<PAGE>

structure including a new bank financing agreement and a new line of credit with
a commercial lender.

         In November 1994, the Company restructured its Series A Convertible
Preferred Stock (as of June 30, 1994 values) which was due to be redeemed on
December 31, 1994. Of the 800,000 shares of outstanding Series A Convertible
Preferred Stock, 50,000 outstanding shares of Series A Convertible Preferred
Stock and accrued dividends aggregating $225,000 were converted into a one (1)
year term loan with monthly principal and interest payments and bearing interest
at the rate of prime plus 3-1/2%. This note was paid off in 1995. The Company
also granted warrants to purchase 10,000 shares of its Common Stock at $2.00 per
share expiring in 1999. The remaining 750,000 shares plus accrued dividends of
approximately $1,071,000 were exchanged for 687,500 shares of Series B
Convertible Preferred Stock and 1,945,625 shares of Series C Convertible
Preferred Stock. The Series B Convertible Preferred Stock is convertible at the
option of the holder into Common Stock or cash, at $2.00 per share maturing
December 31, 1999. Dividends accrue on the Series B Convertible Preferred Stock
at the rate of 8% per year. These dividends may be paid in cash or accrued at
the option of the Company. If not paid they will be added to the face amount of
the Series B Convertible Preferred Stock at the price of $2.00 per share.

         In the event that during the next five (5) years the market price of
the Company's Common Stock as quoted on Nasdaq attains a price of $6.00 per
share and maintains such price for at least 90 days, the Series B Convertible
Preferred Stock will be automatically converted into Common Stock.

         The Series C Convertible Preferred Stock is automatically convertible
at $1.00 per share into 1,945,625 shares of Common Stock on December 30, 2004,
or earlier at the option of the holder. There are no dividends payable or
accrued on the Series C Convertible Preferred Stock.

         In the event that during the next (5) years the market price of the
Company's Common Stock as quoted on Nasdaq attains a price of $3.00 per share
and maintains such price for at least 90 days, the Series C Convertible
Preferred Stock will be automatically converted into Common Stock.

         In November of 1994, the Company renegotiated the terms of its bank
borrowing facilities. The existing bank loan of $1,514,000 was replaced with a
new loan agreement. In connection with this new loan, the Company made a
$600,000 payment against the existing principal balance. The remaining principal
balance of $914,000 was converted into a four (4) year term loan which bears
interest at a rate of prime plus 2-1/2%. The principal is amortized on a monthly
basis at the rate of $12,500 per month with a balloon payment of $326,836 due
October 1998. In addition, the bank exchanged its first lien on the Company's
assets for a second lien position. The Company also extended the term of the
warrants to purchase 100,000 shares of Common Stock being held by the bank for
an additional three (3) years and reduced the exercise price to $2.00 per share.


                                       17
<PAGE>


         In November of 1994, simultaneously with the restructuring of its bank
loan agreement described above, the Company entered into a line of credit
arrangement with a lending institution. The agreement provides for a revolving
collateralized line of credit of up to $2,000,000. The line of credit is secured
by basically all assets of the Company. The Company can borrow up to 70% of its
eligible accounts receivable. The interest rate on the facility is prime plus
3-1/2%. In December 1995, the Company extended the term of its working capital
line of credit which was due to expire in November 1996 to January 1997.

         On September 29, 1994, the Board of Directors approved the 1994 Stock
Option Plan and authorized the issuance of up to 1,000,000 shares of Common
Stock of the Company upon the exercise of Incentive and Non Statutory Stock
Options which may be granted pursuant to the Plan. On March 21, 1996, the Board
of Directors approved, subject to shareholder approval at the next shareholders
meeting, the 1996 Stock Plan which authorizes the issuance of up to an
additional 500,000 shares of Common Stock of the Company pursuant to Incentive
and Non-Statutory Stock Options as well as awards of Common Stock and rights to
purchase Common Stock.

         At the time of the settlement in November 1994 of Shamrock's patent
infringement suit against the Company, the Company and Shamrock entered into the
Toll Processing Agreement pursuant to which Shamrock agreed to purchase from the
Company $3.3 million of PTFE processing services over a period of 18 months
ending May, 1996 at prices which provided for a gross profit to the Company. On
November 1, 1995, the Toll Processing Agreement was extended and modified. The
extension covers a period of 18 months which commenced January 1, 1996 and ends
on June 30, 1997, unless extended at Shamrock's option for additional three
month increments through December 31, 1997. During the extension period the
Company has agreed to provide, and Shamrock has agreed to use, certain minimum
levels of processing services at prices which will result in a gross profit to
the Company for providing these services. If the extension agreement is
performed in accordance with its terms, the Company estimates that Shamrock and
Precision will purchase approximately $4.2 million of PTFE processing services
from January 1, 1996 through June 30, 1997. The Company has agreed that it will
not process PTFE for any other entity during and after the termination of its
agreement with Shamrock. MSI gave to Shamrock as security a confession of
judgment in the amount of $1,250,000 to be entered only if any agreement listed
in the Settlement Agreement is rejected under the provisions of the Bankruptcy
Code and only if a proceeding is commenced in the future in which the Company is
the bankrupt party. The Confession of Judgment is limited to the earlier of the
rejection of an agreement by the Bankruptcy Court and 120 days after the
termination of the original Toll Processing Agreement on December 31, 1995.

         As part of the settlement of the Shamrock litigation, the Company
issued warrants to purchase 75,000 shares of its Common Stock at $2.00 per share
to Shamrock which expire in 1999, and issued 25,000 shares of the Company's
Common Stock outright. Shamrock also received payment of $62,500 in cash. Also
in conjunction with the settlement, the Company issued warrants to purchase
40,000 shares of its common stock at $2.00 per share to each of two directors of
the Company for services rendered in connection with the settlement. The
warrants expire in 1999.


                                       18

         In April 1995, the Company entered into a $440,000 line of credit with
a finance company to finance the acquisition of surgical instruments and fixed
assets. The line of credit bears interest at the rate of prime plus 3-1/2%. Once
a draw-down on the line is taken, the interest rate for the specific lease is
set permanently for that lease. The Company expects to fully utilize this line
for fixed asset acquisitions during 1996.

Inflation

         The Company does not anticipate that inflation will have any
significant effect on its business particularly since the United States, the
only market in which the Company currently intends to operate, is presently
experiencing a relatively low rate of inflation.

Certain Factors That May Affect Future Results

         From time to time, information provided by the Company, statements made
by its employees or information included in its filings with the Securities and
Exchange Commission (including this Form 10-KSB) may contain statements which
are not historical facts, so-called "forward-looking statements," which involve
risks and uncertainties. Forward-looking statements are made pursuant to the
safe harbor provisions of the Private Securities Litigation Reform Act of 1995.
In particular, statements made above in "Item 2. Description of Property"
relating to the suitability of the Company's facilities and equipment for future
operations and the availability of additional facilities and equipment in the
future and in "Item 6. Management's Discussion and Analysis of Financial
Condition and Results of Operations" relating to the sufficiency of funds for
the Company's working capital requirements during 1996, the Company's
expectation that future cash flow will continue to be provided from operations
and the Company's not presently anticipating that inflation will have any
significant impact on its business may be forward-looking statements. The
Company's actual future results may differ significantly from those stated in
any forward-looking statements. Factors that may cause such differences include,
but are not limited to, the factors discussed below. Each of these factors, and
others, are discussed from time to time in the Company's filings with the
Securities and Exchange Commission.

         The Company's future results are subject to substantial risks and
uncertainties. The Company has operated at a loss or a very small profit for its
entire history and there can be no assurance of its ever achieving consistent
profitability. The Company had working capital of approximately $1,607,000 as at
December 31, 1995 and has a working capital line of credit which expires January
31, 1997. The Company may require additional working capital in the future and
there can be no assurance that such working capital will be available on
acceptable terms, if at all. The contract sterilization of disposable medical
products marketplace is highly competitive and many of the Company's competitors
have significantly greater financial and other resources than the Company. The
failure of the Company to continue to compete effectively with existing or new
competitors could result in price erosion, decreased margins and decreased
revenues, any or all of which could have a material adverse effect on the
Company's business, results of operations and financial condition. The Company
historically has relied on a 




                                       19
<PAGE>

relatively small number of customers, including Shamrock and Precision, for a
large percentage of its total revenues. Loss of, or a decrease in orders from,
any one or more of these customers could have a material adverse effect on the
Company's results of operations. In particular, the loss of business from
Shamrock or Precision in spite of the amended toll processing agreement would
have a material adverse effect on the Company's business and results of
operations. The Company's healthcare provider customers are all located in the
New York metropolitan area and Long Island, New York. Any factors affecting this
market generally could have a material adverse effect on the Company's business,
results of operations and financial condition. The Company is subject to
government regulation in certain aspects of its operations and is required to
install certain pollution control equipment. Any failure to comply with
applicable government regulations or to properly and timely install appropriate
pollution control equipment could have a material adverse effect on the
Company's business, results of operations and financial condition. The Company's
future success will depend in part on its ability to convince hospitals and
other healthcare providers to utilize the Company's off-site sterilization
services as opposed to their own on-site facilities. Hospitals may resist this
change for a number of reasons, including the preferences of hospital staffs
which may wish to preserve their existing staffing intact, labor unions which
may resist any staffing reductions and the ongoing consolidation of hospitals
which may impact the willingness of hospital administrators to make operational
decisions on a timely basis and which may affect a hospital's decision to
utilize an off-site processor as opposed to retaining one or more of the
consolidated hospital group's central sterilization facilities to provide
services for the entire group. The Company relies upon the know-how of its
employees and upon its hospital tracking software to efficiently conduct its
business. Any invalidation of these intellectual property rights or lengthy and
expensive defense of these rights could have a material adverse effect on the
Company.

         The Company's quarterly and annual operating results are affected by a
wide variety of factors that could materially adversely affect revenues and
profitability, including: competitive pressures on selling prices and margins;
the timing and cancellation of customer orders; the lengthy sales cycle of the
Company's sterilization services to healthcare organizations; the Company's
ability to maintain state-of-the-art sterilization facilities and the
corresponding timing and amount of capital expenditures, particularly if the
Company executes its plan for expansion; and the introduction of new services by
the Company's competitors. As a result of the foregoing and other factors, the
Company may experience material fluctuations in future operating results on a
quarterly or annual basis which could materially and adversely affect its
business, operating results and stock price. Although the Company achieved a
positive net income per share of Common Stock for the fiscal year ended December
31, 1995, the Company expects to incur a net loss per share of Common Stock for
the first fiscal quarter of 1996.

To the Board of Directors and
Shareholders of Medical Sterilization, Inc.:

         We have audited the financial statements of MEDICAL STERILIZATION, INC.
listed in Item 7 of this Form 10-KSB. 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 Medical
Sterilization, Inc. at December 31, 1995 and the results of its operations and
its cash flows for each of the two years in the period ended December 31, 1995
in conformity with generally accepted accounting principles.

                          NOTES TO FINANCIAL STATEMENTS

1.       Formation and Business:

         Medical Sterilization, Inc. (the "Company") was incorporated in New
York State on May 27, 1982. The Company completed construction of its expanded
facility in 1985 and initiated off-site sterilization services to health care
providers and to manufacturers of disposable medical products, principally in
the New York Metropolitan area. The Company also provides contract sterilization
services to other customers. In addition, the Company uses its radiation
facility at Syosset to irradiate polytetrafluoroethylene ("PTFE"), which can
then be ground into very small particles for use primarily as an additive to
printing inks and as a lubricant. The Company leases its facility in which it
has installed steam and radiation sterilization equipment.

         One customer accounted for approximately 30% and 35% of total revenue
for 1995 and 1994, respectively. One customer accounted for 40% of revenue from
contract sterilization services in 1995 and two customers accounted for 43% of
such revenues in 1994. One customer accounted for all of the revenue from PTFE
processing service in 1995 and 1994 (see Note 13).

2.       Summary of Significant Accounting Policies:

         Inventory:
         ----------
         Inventory is stated at the lower of first-in, first-out cost or market.

         Fixed Assets:
         -------------
         Depreciation and amortization are computed using the straight-line
method over the estimated useful lives of the related assets (ranging from 3 to
20 years) and, for leasehold improvements, over the shorter of the useful life
of the improvement or the term of the lease. Shrinkage-loss of surgical
instruments and containers is provided based upon incurred losses.

         Maintenance and repairs are charged to income in the year incurred.
Expenditures which significantly improve or extend the life of the assets are
capitalized.

         Upon disposal, the cost and related accumulated depreciation are
removed from the respective accounts and any resulting gain or loss is included
in income.

         Revenue Recognition:
         --------------------
         The Company records revenue for hospital services monthly, in
accordance with contractual terms. Revenues for other sterilization and
radiation services are recorded upon the completion of processing.

         Concentration of Credit Risk:
         -----------------------------

         Trade receivables arise from long-term and short-term contracts with
healthcare providers in its area of operations. The Company provides instrument
sterilization services pursuant to contracts with 28 hospitals and ambulatory
surgi-centers. In addition, the Company sterilizes disposable medical products
for 30 disposable medical products manufacturers. Receivables also arise from
the processing of polytetrafluorethylene "PTFE," also known as "Teflon." This
process is solely performed for Shamrock Technologies, Inc. To reduce credit
risk, the Company performs credit evaluations of its customers but does not
generally require collateral Credit risk is affected by conditions of
occurrences within the economy and the healthcare industry. The Company
establishes an allowance for doubtful accounts based upon factors surrounding
the credit risk of specific customers, historical trends and other information.

         At December 31, 1995, four customers represented 42% of the accounts
receivable balance. The loss of any one customer could have a significant impact
on the Company's financial position or results of operations.

         Income Taxes:
         -------------

         The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes",
which requires that deferred income taxes be recognized for the tax consequences
in future years of differences between the tax bases of assets and liabilities
and their financial reporting amounts at each year-end based on enacted tax laws
and statutory rates applicable to the periods in which the differences are
expected to effect taxable income. Valuation allowances are established when
necessary to reduce deferred tax assets to the amount expected to be realized.

         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.

         Prospective Accounting Change:
         ------------------------------

         In March 1995, the Financial Accounting Standard Board issued SFAS No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of." Adoption of the new standard is required for fiscal
years beginning after December 15, 1995. Management estimates that the new
accounting principle will not have a material impact on the Company's financial
position or results of operations.

         In October 1995, the Financial Accounting Standards Board issued SFAS
No. 123, "Accounting for Stock-Based Compensation," which establishes financial
accounting and 




                                      F-9
<PAGE>

reporting standards for stock based plans. The Statement, which becomes
effective in 1996, requires the Company to choose between accounting for
issuance of stock and other equity instruments to employees based on their fair
value or disclosing the pro forma effects such accounting would have had on the
Company's net income and earnings per share. The Company has begun to gather the
documentation necessary to address the impact of this Statement, although it has
not yet decided which method it will utilize relating to its stock based
employee plans.

         Net Income (Loss) Per Share of Common Stock:
         --------------------------------------------

         Net income (loss) per share of common stock is based on the weighted
average number of common shares outstanding during each period adjusted for
dividends on preferred stock. Common stock equivalents of 2,118,919 resulting
from Convertible Series C Preferred Stock and the effects of options and
warrants have been included in the calculation of weighted average shares
outstanding in 1995. Common stock equivalents have been excluded in 1994 from
the computation of net loss per share of common stock since the result would be
anti-dilutive.

         Reclassifications:
         ------------------

         Certain items in the 1994 financial statements have been reclassified
to conform to the 1995 presentation.

3.       Fixed Assets:

         At December 31, 1995, fixed assets consists of:

         Included in fixed assets at December 31, 1995 are assets recorded under
capital leases comprised of:


           Machinery and equipment                                 $463,917
           Less, accumulated amortization                           370,876
                                                                  ---------
                                                                  $  93,041
                                                                  =========

                                      F-10
<PAGE>

         Repairs and maintenance charged to operations for the years ended
December 31, 1995 and 1994 amounted to approximately $180,000 and $160,000,
respectively.

4.       Employee Benefit Plans:

         The Company adopted a 401(k) defined contribution plan commencing with
the 1995 fiscal year which allows participants to make contributions based on a
percentage of their earnings. The Company's contribution for the fiscal year
ended December 31, 1995 was approximately $22,000.

5.       Income Taxes:

         During 1995, the Company utilized approximately $320,000 of net
operating loss carryforwards for income tax purposes. Such utilization served to
eliminate the Company's current tax liability.

         Reconciliation of the federal statutory tax rate to the effective tax
rate is as follows:

                                                      1995           1994

         Deferred income taxes reflect the net tax effects of temporary
differences between the carrying amount of assets and liabilities for financial
reporting purposes and the amounts used for income tax purposes. Significant
components of the Company's deferred tax assets and liabilities at December 31,
1995 are as follows:


           Deferred tax liability:
                Depreciation                                      ($  991,831)
                                                                   ----------
                    Total deferred tax liability                     (991,831)

           Deferred tax assets:
                Net operating loss carryforwards                    3,903,511

           Less valuation allowance                                (2,942,304)
                                                                   ----------

         The Company has established a valuation allowance equal to the net
deferred tax asset amount as it is more likely than not that the deferred tax
asset will not be realized. The net change in the total valuation allowance for
the year ended December 31, 1995 was a decrease of $99,900 related primarily to
utilization of the net operating loss carryforwards.

         (a) During 1991, the Board of Directors approved a resolution to repay
the debt to the President and the director at a rate not to exceed 10% of the
profits in any quarter and to be limited further by the Company's cash
availability.

                  On September 29, 1994, the Board of Directors revised the
prior resolution with regard to payments of the debt to the President and
Director to authorize the payment of $50,000 per year to the President and a
pro-rata amount ($8,333) to the Director. The loans are subordinate to the bank
borrowings.

         (b) In November of 1994, the Company renegotiated the term of its bank
borrowing facilities. The existing bank loan of $1,514,000 was replaced with a
new loan agreement. In connection with this new loan, the Company made a
$600,000 payment against the existing principal balance. The remaining principal
balance of $914,000 was converted to a four (4) year term loan which bears
interest at a rate of prime plus 2-1/2%. The principal is amortized on a monthly
basis at the rate of $12,500 per month with a balloon payment of $326,836 due in



                                      F-12

October, 1998. In addition, the bank exchanged its first lien on the Company's
assets for a second lien position. The Company also extended the term of the
warrants being held by the bank for an additional three (3) years and reduced
the exercise price to $2 per share. (See Note 9).

         (c) In November of 1994, simultaneously with the restructuring of its
bank loan agreement described above, the Company entered into a line of credit
arrangement with a lending institution. The agreement provides for a revolving
collateralized line of credit of up to $2,000,000. The line of credit is
collateralized by substantially all assets of the Company. The Company can
borrow up to 70% of its eligible accounts receivable. The interest rate on the
facility is prime plus 3-1/2%. In December 1995, the expiration date was
extended to January 1997. The Company issued to its commercial lender warrants
to purchase 50,000 shares of its Common Stock at $2.00 per share, expiring in
1999.

         Average monthly borrowings under the revolving line of credit described
above for the year ended December 31, 1995 amounted to $1,087,600 and the
related weighted average interest rate was 12.25%. Maximum borrowings at any
month end were $1,235,600 in 1995.

         The approximate aggregate principal payment requirements for long-term
debt are as follows: 1996 - $209,000; 1997 - $1,376,000; 1998 - $510,000; 1999 -
$58,000; and thereafter - $0.

         Fair value of long-term debt approximates recorded amounts as similar
borrowings have been offered to the Company at comparable rates and maturities.

7.       Capital Leases:

         Future minimum payments as of December 31, 1995 under capital leases
for equipment are as follows:

8.       Preferred Stock (See Note 9):

         In November 1994, the Company restructured its Series A Convertible
Preferred Stock (as of June 30, 1994 values) which was due to be redeemed on
December 31, 1994. Of the 800,000 shares ($2,400,000 face value) of outstanding
Series A Convertible Preferred Stock, 50,000 outstanding shares ($150,000 face
value) and accrued dividends aggregating $225,000 




                                      F-13
<PAGE>

were converted into a one (1) year term loan with monthly principal and interest
payments. This loan bears interest at the rate of prime plus 3 1/2%. This note
was paid off in 1995. The Company also granted warrants to purchase 10,000
shares of its Common Stock at $2.00 per share expiring in 1999. The remaining
750,000 shares ($2,250,000 face value) plus accrued dividends of approximately
$1,071,000 were exchanged for $1,375,000 of Series B Convertible Preferred Stock
and $1,945,625 of Series C Convertible Preferred Stock. The Series B Convertible
Preferred Stock is convertible at $2.00 per share into 687,500 shares of Common
Stock. This Series B Convertible Preferred Stock is convertible at the option of
the holder into Common Stock or cash, at $2.00 per share maturing December 31,
1999. Dividends accrue on this Series B Convertible Preferred Stock at the rate
of 8% per year. These dividends may be paid in cash or accrued at the option of
the Company. If not paid, accrued dividends are added to the face amount of the
Series B Convertible Preferred Stock.

         In the event during the next five (5) years, the market price of the
Company's Common Stock as quoted on Nasdaq attains a price of $6.00 per share
and maintains such price for at least 90 days, the Series B Convertible
Preferred Stock will be automatically converted into Common Stock.

         The Series C Convertible Preferred Stock is automatically convertible
at $1.00 per share into 1,945,625 shares of Common Stock on December 30, 2004,
or earlier at the option of the holder. There are no dividends payable nor
accrued on the Series C Convertible Preferred Stock.

         In the event during the next five (5) years, the market price of the
Company's Common Stock as quoted on Nasdaq attains a price of $3.00 per share
and maintains such price for at least 90 days, the Series C Convertible
Preferred Stock will be automatically converted into Common Stock.

         In February 1993, for his guarantee for the issuance of a $100,000
bond, the Company issued warrants to purchase 2,500 shares of Common Stock at a

Company.

         In November 1994, as part of the settlement of the Shamrock litigation
(Note 13) the Company issued warrants to purchase 75,000 shares of its common

with the settlement, the Company issued warrants to purchase 40,000 shares of
its common stock at $2.00 per share to each of two directors of the Company in
consideration of their efforts in achieving the settlement. The warrants expire
in 1999.

         In March 1994 the Company issued warrants to purchase 25,000 shares of

         In connection with the financing described in Note 6(b), the Company
extended the term of a warrant to purchase an aggregate of 100,000 shares of
common stock for three years (to expire in 1998) and reduced the exercise price
to $2.00 per share.

         In November 1994, the Company issued to a financial institution
warrants to purchase 50,000 shares of its common stock at $2.00 per share,
expiring in 1999.

         In December 1994, in connection with the conversion of 50,000 shares of

1989 and 1991, authorized the issuance, not later than May 11, 1993, of options
to purchase up to 800,000 shares of common stock. Options granted under the Plan

         Incentive stock options may be granted only to key employees, including
officers or directors who are employees of the Company, and are exercisable
immediately or in installments following a period of two years after grant but

granted to holders of more than 10% of the Company's voting stock). The exercise
price must be at least equal to the fair market value of the Company's common
stock on the date granted (110% in the case of 10% shareholders). At December
31, 1995 incentive stock options for an aggregate of 282,250 shares of common
stock at an exercise price of $0.74 were outstanding.

         Non-qualified stock options may be granted under the Plan or otherwise

and may be below the fair market value of the Company's common stock on the date
of grant. At December 31, 1995, non-qualified options for an aggregate of
612,500 shares of common stock at exercise prices ranging from $.10 to $9.00,
were outstanding.

         In July 1994 the New York State Department of Environmental
Conservation announced stringent standards with regard to the emission of ozone.
The Company is working with State and County authorities on an established
timeline to bring the Company into compliance with these standards. The Company
has hired consultants to measure the Company's ozone emissions and, in
conjunction with State and County authorities, to design necessary pollution
control equipment to meet these standards. the estimated cost of such pollution
control equipment is approximately $300,000. In the event the Company does not
install such pollution control equipment, it will not obtain a permit to operate
its electron beam accelerator, which would result in a significant reduction in
revenues and would have a material adverse effect on the Company's business,
results of operations and financial condition.

         13.      Litigation:

         (a) In November 1994, the Company reached an agreement with the
plaintiff, Shamrock Technologies Inc. ("Shamrock"), in which the judgment that
had been awarded in the approximate amount of $3,500,000, including interest,
was satisfied. The Company had given to Shamrock, as security, a confession of
judgment in the amount of $1,250,000.


                                      F-17
<PAGE>


         As part of the settlement, Shamrock agreed to purchase $3.3 million of
tolling or processing services for 18 months beginning November 1994, at prices
which provide a gross margin to the Company on such services. At the end of the
tolling agreement the Company must refrain from participating in the PTFE
processing business.

         In November 1995, the Company and Shamrock entered into an agreement
modifying and extending the toll processing agreement. The agreement was
extended through June 30, 1997 with Shamrock having the right to extend it
further to December 31, 1997.

         As part of the settlement of the Shamrock litigation the Company issued
warrants to purchase 75,000 shares of its common stock at $2.00 per share to
Shamrock which expire in 1999, and issued 25,000 shares of the Company's common
stock to Shamrock. Shamrock also received payment of $62,500 in cash. Also in
conjunction with the settlement, the Company issued warrants to purchase 40,000
shares of its common stock at $2.00 per share to each of two directors of the
Company in consideration of their efforts in achieving the settlement. The
warrants expire in 1999.

         (b) The Company entered into a deferred payment plan agreement with the
New York State Department of Taxation and Finance to satisfy its obligation
under a final assessment related to a prior period sales tax audit. At December
31, 1995 the Company had completed all payments due under this agreement and a
satisfaction of judgment was issued by the New York State Department of Taxation
and Finance.

                                      -3-

<PAGE>

                  (iv) The rights to which the holders of the shares of stock of
such series shall be entitled upon any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation;
                  (v) The terms, if any, upon which the shares of stock of such
series shall be convertible into, or exchangeable for, shares of stock of any
other class or classes or of any other series of the same or any other class or

                  (vi) Any other designations, preferences and relative,
participating, optional or other special rights, and qualifications, limitations
or restrictions thereof so far as they are not inconsistent with the provisions
of the Certificate of Incorporation, as amended, and to the full extent now or
hereafter permitted by the laws of the State of New York.
                  All shares of the Preferred Stock of any one series shall be
identical to each other in all aspects, except that shares of any one series
issued at different times may differ as to the dates from which dividends
thereon, if cumulative, shall be cumulative.
            B.    Common Stock.
                  (i) Whenever dividends upon the Preferred Stock at the time
outstanding shall have been paid in full for all past dividend periods or
declared and set apart for payment, such dividends as may be determined by the
Board of Directors may be declared by the Board of Directors and paid from time

and expressed in any resolution or resolutions adopted by the Board of Directors
including any resolutions providing for the issuance of Preferred Stock.

<PAGE>

payment to the holders of the Preferred Stock at the time outstanding of the
full amounts to which they shall be entitled, shall be divided and distributed
among the holders of Common Stock according to their respective shares.
                  (iii) Each holder of the Common Stock shall have one vote in
respect of each share of such stock held by him.
            C. Pre-emptive Rights. No shareholder of this corporation shall have
a pre-emptive right because of his shareholdings to have first offered to him
any part of any of the presently authorized shares of this corporation hereafter
issued, optioned, or sold, or any part of any debenture, bonds, notes, or
securities of this corporation convertible into shares hereafter issued,
optioned, or sold by the corporation. This provision shall operate to defeat
rights in all shares and classes of shares now authorized and in all debentures,
bonds, notes, or securities of the corporation which may be convertible into
shares, and also to defeat pre-emptive rights in any and all shares and classes
of shares and securities convertible into shares which this corporation may be
hereafter authorized to issue by any amended certificate duly filed. Thus, any
and all of the shares of this corporation presently authorized, and any and all
debentures, bonds, notes, or securities of this corporation convertible into
shares and any and all of the shares of this corporation which may hereafter be
authorized, may at any time be issued, optioned, and contracted for sale, and/or
sold and disposed of by direction of the Board of Directors of this corporation
to such persons, and upon such terms and conditions as may to the Board of
Directors seem proper and advisable, without first offering the said shares or
securities or any part thereof to existing shareholders.
            D.    Stock Rights and Options.  The corporation shall have the
power to create and issue rights, warrants, or options entitling the
holders thereof to purchase from the

                                      -5-

<PAGE>

corporation any shares of its capital stock of any class or classes, upon such
terms and conditions and at such time and prices as the Board of Directors may
provide, which terms and conditions shall be incorporated in an instrument or
instruments evidencing such rights. In the absence of fraud, the judgment of the
Directors as to the adequacy of consideration for the issuance of such rights or
options and the sufficiency thereof shall be conclusive.

      FIFTH: The Secretary of State is designated as the agent of the
corporation upon whom process against it may be served, and the post office
address to which the Secretary of State shall mail a copy of such process served
upon him is c/o Murtagh, Cohen & Byrne, 1122 Franklin Avenue, Garden City, New
York 11530."
      5. The Restatement of the Certificate of Incorporation was authorized by
the vote of the Board, followed by the affirmative vote of the holders of a
majority of all outstanding shares entitled to vote thereon at a meeting of
shareholders.
      IN WITNESS WHEREOF, we have signed this Restated Certificate of
Incorporation on the 22nd day of May, 1989.

                          CERTIFICATE OF INCORPORATION
                                       OF
                           MEDICAL STERILIZATION, INC.

                Under Section 805 of the Business Corporation Law
         We, Kennard H. Morganstern and Harvey Cohen, being respectively the
President and Secretary of Medical Sterilization, Inc., hereby certify:
         (1)  The name of the Corporation is

                           MEDICAL STERILIZATION, INC.

         (2) The Certificate of Incorporation was filed on May 27, 1982 under
the name General Sterilization, Inc. Restated Certificates of Incorporation were
filed on May 12, 1983, August 5, 1983 and May 24, 1989.
         (3) The Certificate of Incorporation is amended by the addition of a
provision stating the number, designation, relative rights, preferences and
limitations of Preferred Shares of a series of the par value of $.01 per share,
as fixed by the Board of Directors before the issuance of such series, under
authority contained in the Certificate of Incorporation and as permitted by
Section 502 of the Business Corporation Law as follows:
         "1. Number of Shares. One Million (1,000,000) shares of authorized
Preferred Stock of the par value of $.01 each shall be issued in and as a series
to be designated "Series A Convertible Preferred Stock." The term Preferred
Stock, as used herein, shall include all of the shares of Preferred Stock
authorized by the Certificate of Incorporation, of which Series A Convertible
Preferred Stock is the first series.

         2.       Voting.

                  2A. General. Except as may be otherwise provided in these
terms of the Series A Convertible Preferred Stock or by law, the Series A
Convertible Preferred Stock shall vote together with all other classes and 
series of stock of the  Corporation  as a single class on all 



<PAGE>

actions to be taken by the  stockholders of the  Corporation.  Each share of
Series A Convertible  Preferred  Stock shall entitle the holder  thereof to such
number  of votes per share on each  such  action  as shall  equal the  number of
shares of Common Stock (including fractions of a share) into which each share of
a Series A Convertible Preferred Stock is then convertible.

                  2B. Board Size. The Corporation shall not, without the written
consent or affirmative vote of the holder of at least two-thirds of the then
outstanding shares of Series A Convertible Preferred Stock, given in writing or
by vote at a meeting, consenting or voting (as the case may be) separately as a
series, increase the maximum number of directors constituting the Board of
Directors to a number in excess of eleven (11).

                  2C. Board Seats. The holders of the Series A Convertible
Preferred Stock, voting as a separate series, shall be entitled to elect one (1)
director of the Corporation. The holders of the Common Stock, voting as a
separate class, shall be entitled to elect the remaining directors of the
Corporation. Notwithstanding the foregoing or anything else to the contrary
provided in the Restated Certificate of Incorporation, if the Corporation fails
or refuses, for any reason or for no reason, to redeem on the Redemption Date
(as defined in paragraph 7) all of the then outstanding shares of Series A
Convertible Preferred Stock in accordance with the terms and provisions of
paragraph 7, the holders of the Series A Convertible Preferred Stock, voting as
a separate series, shall be entitled to elect a majority of the directors of the
Corporation. At any meeting (or in a written consent in lieu thereof) held for
the purpose of electing directors, the presence in person or by proxy (or the
written consent) of the holders of a majority of the shares of Series A
Convertible Preferred Stock then outstanding shall constitute a quorum of the
Series A Convertible Preferred Stock for the election of directors to be elected
solely by the holders of the Series A Convertible Preferred Stock or jointly by
the holders of the Series A Convertible Preferred Stock and the Common Stock. A
vacancy in any directorship elected by the holders of the Series A Convertible
Preferred Stock shall be filled only by vote or written consent of the holders
of the Series A Convertible Preferred Stock.

         3. Dividends. The holders of the Series A Convertible Preferred Stock
shall be entitled to receive, out of funds legally available therefor, when and
if declared by the Board of Directors, quarterly dividends at the rate per annum
of $.30 per share (the "Accruing Dividends"). Accruing Dividends shall accrue
from day to day, whether or not earned or declared, and shall be cumulative from
the date of issuance of the Series A Convertible Preferred Stock.

         4. Liquidation. Upon any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, the holders of the shares of
Series A Convertible Preferred Stock shall first be entitled, before any
distribution or payment is made upon any stock ranking on liquidation junior to
the Series A Convertible Preferred Stock, to be paid an amount equal to $3.00
per share plus, in the case of each share, an amount equal to all Accruing
Dividends unpaid thereon (whether or not declared) and any other dividends
declared but unpaid thereon, computed to the date payment thereof is made
available, such amount payable with respect to one share of Series A Convertible
Preferred Stock being sometimes 


                                       2
<PAGE>

referred to as the "Liquidation Preference Payment" and with respect to all
shares of Series A Convertible Preferred Stock being sometimes referred to as
the "Liquidation Preference Payments." If upon such liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, the assets to
be distributed among the holders of Series A Convertible Preferred Stock shall
be insufficient to permit payment in full to the holders of Series A Convertible
Preferred Stock of the Liquidation Preference Payments, then the entire assets
of the Corporation to be so distributed shall be distributed ratably among the
holders of Series A Convertible Preferred Stock. Upon any such liquidation,
dissolution or winding up of the Corporation, immediately after the holders of
Series A Convertible Preferred Stock shall have been paid in full the
Liquidation Preference Payments, the remaining net assets of the Corporation
available for distribution shall be distributed ratably among the holders of
Series A Convertible Preferred Stock and Common Stock (with each share of Series
A Convertible Preferred Stock being deemed, for such purpose, to be equal to the
number of shares of Common Stock (including fractions of a share) into which
such share of Series A Convertible Preferred Stock is convertible immediately
prior to the close of business on the business day fixed for such distribution).
Written notice of such liquidation, dissolution or winding up, stating a payment
date and the place where said payments shall be made, shall be given by mail,
postage prepaid, or by telex to non-U.S. residents, not less than 20 days prior
to the payment date stated therein, to the holders of record of Series A
Convertible Preferred Stock, such notice to be addressed to each such holder at
its address as shown by the records of the Corporation. The consolidation or
merger of the Corporation into or with any other entity or entities which
results in the exchange of outstanding shares of the Corporation for securities
or other consideration issued or paid or caused to be issued or paid by any such
entity or affiliate thereof, and the sale or transfer by the Corporation of all
or substantially all its assets, shall be deemed to be a liquidation,
dissolution or winding up of the Corporation within the meaning of the provision
of this paragraph 4. For purposes hereof, the Common Stock shall rank on
liquidation junior to the Series A Convertible Preferred Stock.

         5. Restrictions. At any time when shares of Series A Convertible
Preferred Stock are outstanding, except where the vote or written consent of the
holders of a greater number of shares of the Corporation is required by law or
by the Restated Certificate of Incorporation, and in addition to any other vote
required by law or the Restated Certificate of Incorporation, without the
approval of the holders of at least two-thirds of the then outstanding shares of
Series A Convertible Preferred Stock, given in writing or by vote at a meeting,
consenting or voting (as the case may be) separately as a series, the
Corporation will not:


                  5A. Create or authorize the creation of any additional class
or series of shares of stock unless the same ranks junior to the Series A
Convertible Preferred Stock as to the distribution of assets on the liquidation,
dissolution or winding up of the Corporation, or increase the authorized amount
of the Series A Convertible Preferred Stock or increase the authorized amount of
any additional class or series of shares of stock unless the same ranks junior
to the Series A Convertible Preferred Stock as to the distribution of assets on
the liquidation, dissolution or winding up of the Corporation, or create or
authorize any obligation or security convertible into shares of Series A
Convertible Preferred Stock or into shares of any other class or series of stock
unless the same ranks junior of the Series A Convertible Preferred Stock as to
the distribution of assets on the liquidation, dissolution or winding up of the
Corporation, 



                                       3
<PAGE>

whether any such creation, authorization or increase shall be by means of
amendment to the Restated Certificate of Incorporation or by merger,
consolidation or otherwise;

                  5B.      Consent to any liquidation, dissolution or winding
up of the Corporation or consolidate or merge into or with any other entity or 
entities or sell or transfer all or substantially all its assets;

                  5C.      Amend, alter or repeal its Restated Certificate of 
Incorporation or By-laws in a manner which adversely affects the holders of 
Series A Convertible Preferred Stock;

                  5D. Purchase or set aside any sums for the purchase of, or pay
any dividend or make any distribution on, any shares of stock other than the
Series A Convertible Preferred Stock, except for dividends or other
distributions payable on the Common Stock solely in the form of additional
shares of Common Stock and except for the purchase of shares of Common Stock
from former employees of the Corporation who acquired such shares directly from
the Corporation, if each such purchase is made pursuant to contractual rights
held by the Corporation relating to the termination of employment of such former
employee and the purchase price does not exceed the original issue price paid by
such former employee to the Corporation for such shares; or

                  5E. Redeem or otherwise acquire any shares of Series A
Convertible Preferred Stock except as expressly authorized in paragraph 7 hereof
or pursuant to a purchase offer made pro rata to all holders of the shares of
Series A Convertible Preferred Stock on the basis of the aggregate number of
outstanding shares of Series A Convertible Preferred Stock then held by each
such holder.

         6.       Conversions.  The holders of shares of Series A Convertible 
Preferred Stock shall have the following conversion rights:

                  6A. Right to Convert. Subject to the terms and conditions of
this paragraph 6, the holder of any share or shares of Series A Convertible
Preferred Stock shall have the right, at its option at any time, to convert any
such shares of Series A Convertible Preferred Stock (except that upon any
liquidation of the Corporation the right of conversion shall terminate at the
close of business on the business day fixed for payment of the amount
distributable on the Series A Convertible Preferred Stock) into such number of
fully paid and nonassessable shares of Common Stock as is obtained by (i)
multiplying the number of shares of Series A Convertible Preferred Stock so to
be converted by $3.00 and (ii) dividing the result by the conversion price of
$3.00 per share or, in case an adjustment of such price has taken place pursuant
to the further provisions of this paragraph 6, then by the conversion price as
last adjusted and in effect at the date any share or shares of Series A
Convertible Preferred Stock are surrendered for conversion (such price, or such
price as last adjusted, being referred to as the "Conversion Price"). Such
rights of conversion shall be exercised by the holder thereof by giving written
notice that the holder elects to convert a stated number of shares of Series A
Convertible Preferred Stock into Common Stock and by surrender of a certificate
or certificates for the shares so to be converted to the Corporation at is
principal office (or such other office or agency of the Corporation as the


                                       4
<PAGE>

Corporation may designate by notice in writing to the holders of the Series A
Convertible Preferred Stock) at any time during its usual business hours on the
date set forth in such notice, together with a statement of the name or names
(with address) in which the certificate or certificates for shares of Common
Stock shall be issued.

                  6B. Issuance of Certificates; Time Conversion Effected.
Promptly after the receipt of the written notice referred to in subparagraph 6A
and surrender of the certificate or certificates for the share or shares of
Series A Convertible Preferred Stock to be converted, the Corporation shall
issue and deliver, or cause to be issued and delivered, to the holder,
registered in such name or names as such holder may direct, a certificate or
certificates for the number of whole shares of Common Stock issuable upon the
conversion of such share or shares of Series A Convertible Preferred Stock. To
the extent permitted by law, such conversion shall be deemed to have been
effected and the Conversion Price shall be determined as of the close of
business on the date on which such written notice shall have been received by
the Corporation and the certificate or certificates for such share or shares
shall have been surrendered as aforesaid, and at such time the rights of the
holder of such share or shares of Series A Convertible Preferred Stock shall
cease, and the person or persons in whose name or names any certificate or
certificates for shares of Common Stock shall be issuable upon such conversion
shall be deemed to have become the holder or holders of record of the shares
represented thereby.

                  6C. Fractional Shares; Dividends; Partial Conversion. No
fractional shares shall be issued upon conversion of Series A Convertible
Preferred Stock into Common Stock and no payment or adjustment shall be made
upon any conversion on account of any cash dividends on the Common Stock issued
upon such conversion. At the time of each conversion, the Corporation shall pay
in cash an amount equal to all dividends, excluding Accruing Dividends, accrued
and unpaid on the shares of Series A Convertible Preferred Stock surrendered for
conversion to the date upon which such conversion is deemed to take place as
provided in subparagraph 6B. In case the number of shares of Series A
Convertible Preferred Stock represented by the certificate or certificates
surrendered pursuant to subparagraph 6A exceeds the number of shares converted,
the Corporation shall, upon such conversion, execute and deliver to the holder,
at the expense of the Corporation, a new certificate or certificates for the
number of shares of Series A Convertible Preferred Stock represented by the
certificate or certificates surrendered which are not to be converted. If any
fractional share of Common Stock would, except for the provisions of the first
sentence of this subparagraph 6C, be delivered upon such conversion, the
Corporation, in lieu of delivering such fractional share, shall pay to the
holder surrendering the Series A Convertible Preferred Stock for conversion an
amount in cash equal to the current market price of such fractional share as
determined in good faith by the Board of Directors of the Corporation.

                  6D. Adjustment of Price Upon Issuance of Common Stock. Except
as provided in subparagraph 6E, if and whenever the Corporation shall issue or
sell, or is, in accordance with subparagraphs 6D(1) through 6D(7), deemed to
have issued or sold, any shares of Common Stock for a consideration per share
less than the Conversion Price in effect immediately prior to the time of such
issue or sale, then, forthwith upon such issue or sale, the 



                                       5
<PAGE>

Conversion Price shall be reduced to the price at which the Corporation issued 
or sold, or is deemed to have issued or sold, such shares of Common Stock.

         For purposes of this subparagraph 6D, the following subparagraphs 6D(1)
to 6D(7) shall also be applicable:

                    6D(1) Issuance of Rights or Options. In case at any time the
          Corporation shall in any manner grant (whether directly or by
          assumption a merger or otherwise) any warrants or other rights to
          subscribe for or to purchase, or any options for the purchase of,
          Common Stock or any stock or security convertible into or exchangeable
          for Common Stock (such warrants, rights or options begin called
          "Options" and such convertible or exchangeable stock or securities
          being called "Convertible Securities") whether or not such Options or
          the right to convert or exchange any such Convertible Securities are
          immediately exercisable, and the price per share for which Common
          Stock is issuable upon the exercise of such Options or upon the
          conversion or exchange of such Convertible Securities (determined by
          dividing (i) the total amount, if any, received or receivable by the
          Corporation as consideration for the granting of such Options, plus
          the minimum aggregate amount of additional consideration payable to
          the Corporation upon the exercise of all such Options, plus, in the
          case of such Options which relate to Convertible Securities, the
          minimum aggregate amount of additional consideration, if any, payable
          upon the issue or sale of such Convertible Securities and upon the
          conversion or exchange thereof, by (ii) the total maximum number of
          shares of Common Stock issuable upon the exercise of such Options or
          upon the conversion or exchange of all such Convertible Securities
          issuable upon the exercise of such Options) shall be less than the
          Conversion Price in effect immediately prior to the time of the
          granting of such Options, then the total maximum number of shares of
          Common Stock issuable upon the exercise of such Options or upon
          conversion or exchange of the total maximum amount of such Convertible
          Securities issuable upon the exercise of such Options shall be deemed
          to have been issued for such price per share as of the date of
          granting of such Options or the issuance of such Convertible
          Securities and thereafter shall be deemed to be outstanding. Except as
          otherwise provided in subparagraph 6D(3), no adjustment of the
          Conversion Price shall be made upon the actual issue of such Common
          Stock or of such Convertible Securities upon exercise of such Options
          or upon the actual issue of such Common Stock upon conversion or
          exchange of such Convertible Securities.

                    6D(2) Issuance of Convertible Securities. In case the
          Corporation shall in any manner issue (whether directly or by
          assumption a merger or otherwise) or sell any Convertible Securities,
          whether or not the rights to exchange or convert any such Convertible
          Securities are immediately exercisable, and the price per share for
          which Common Stock is issuable upon such conversion or exchange
          (determined by dividing (i) the total amount receive or receivable by
          the Corporation as consideration for the issue or sale of such
          Convertible Securities, plus the minimum aggregate amount of
          additional consideration, if any, payable to the Corporation upon the
          conversion or exchange thereof, by (ii) the total maximum number of
          shares of Common Stock issuable upon the conversion or exchange of all
          such Convertible Securities) shall be less than the 



                                       6
<PAGE>

          Conversion Price in effect immediately prior to the time of such issue
          or sale, then the total maximum number of shares of Common Stock
          issuable upon conversion or exchange of all such Convertible
          Securities shall be deemed to have been issued for such price per
          share as of the date of the issue of such Convertible Securities and
          thereafter shall be deemed to be outstanding, provided that (a) except
          as otherwise provided in subparagraph 6D(3), no adjustment of the
          conversion Price shall be made upon the actual issue of such Common
          Stock upon conversion or exchange of such Convertible Securities and
          (b) if any such issue or sale of such Convertible Securities is made
          upon exercise of any Options to purchase any such Convertible
          Securities for which adjustments of the Conversion Price have been or
          are to be made pursuant to other provisions of this subparagraph 6D,
          no further adjustment of the Conversion Price shall be made by reason
          of such issue or sale.

                    6D(3) Change in Option Price or Conversion Rate. Upon the
          happening of any of the following events, namely, if the purchase
          price, provided for in any Option referred to subparagraph 6D(1), the
          additional consideration, if any, payable upon the conversion or
          exchange of any Convertible Securities referred to in subparagraph
          6D(1) or 6D(2), or the rate at which Convertible Securities referred
          to in subparagraph 6D(1) or 6D(2)are convertible into or exchangeable
          for Common Stock shall change at any time (including, but not limited
          to, changes under or by reason or provisions designed to protect
          against dilution), the Conversion Price in effect at the time of such
          event shall forthwith be readjusted to the Conversion Price which
          would have been in effect at such time had such Options or Convertible
          Securities still outstanding provided for such changed purchase price,
          additional consideration or conversion rate, as the case may be, at
          the time initially granted, issued or sold, but only if as a result of
          such adjustment the Conversion Price then in effect hereunder is
          thereby reduced; and on the expiration of any such Option or the
          termination of any such right to convert or exchange such Convertible
          Securities, the Conversion Price then in effect hereunder shall
          forthwith be increased to the Conversion Price which would have been
          in effect at the time of such expiration or termination had such
          Option or Convertible Securities, to the extent outstanding
          immediately prior to such expiration or termination, never been
          issued.

                    6D(4) Stock Dividends. In case the Corporation shall declare
          a dividend or make any other distribution upon any stock of the
          Corporation payable in Common Stock (except for dividends or
          distributions upon the Common Stock), Options or Convertible
          Securities, any Common Stock, Options or Convertible Securities, as
          the case may be, issuable in payment of such dividend or distribution
          shall be deemed to have been issued or sold without consideration.

                    6D(5) Consideration for Stock. In case any shares of Common
          Stock, Options or Convertible Securities shall be issued or sold for
          cash, the consideration received therefor shall be deemed to be the
          amount received by the Corporation therefor, without deduction
          therefrom of any expenses incurred or any underwriting commissions or
          concessions paid or allowed by the Corporation in connection
          therewith. In case any shares of Common Stock, Options or Convertible


                                       7
<PAGE>

          Securities shall be issued or sold for a consideration other than
          cash, the amount of the consideration other than cash received by the
          Corporation shall be deemed to be the fair value of such consideration
          as determined in good faith by the Board of Directors of the
          Corporation, without deduction of any expenses incurred or any
          underwriting commissions or concessions paid or allowed, by the
          Corporation in connection therewith. In case any Options shall be
          issued in connection with the issue and sale of other securities of
          the Corporation, together comprising one integral transaction in which
          no specific consideration is allocated to such Options by the parties
          thereto, such Options shall be deemed to have been issued for such
          consideration as determined in good faith by the Board of Directors of
          the Corporation.

                    6D(6) Record Date. In case the Corporation shall take a
          record of the holders of its Common Stock for the purpose of entitling
          them (i) to receive a dividend or other distribution payable in Common
          Stock, Options or Convertible Securities or (ii) to subscribe for or
          purchase Common Stock, Option or Convertible Securities, then such
          record date shall be deemed to be the date of the issue or sale of the
          shares of Common Stock deemed to have been issued or sold upon the
          declaration of such dividend or the making of such other distribution
          or the date of the granting of such right of subscription or purchase,
          as the case may be.

                    6D(7) Treasury Shares. The disposition of any shares of
          Common Stock owned or held by or for the account of the Corporation
          shall be considered an issue or sale of Common Stock for the purpose
          of this subparagraph 6D.

          6E. Certain Issues of Common Stock Excepted. Anything herein to the
contrary notwithstanding, the Corporation shall not be required to make any
adjustment of the Conversion Price in the case of the issuance of up to an
aggregate of 500,000 shares (appropriately adjusted to reflect the occurrence of
any event described in subparagraph 6F) of Common Stock to directors, officers
or employees of the Corporation in connection with their service as directors of
the Corporation or their employment by the Corporation.

          6F. Subdivision or Combination of Common Stock. In case the
Corporation shall at any time subdivide (by any stock split, stock dividend or
otherwise) its outstanding shares of Common Stock into a greater number of
shares, the Conversion Price in effect immediately prior to such subdivision
shall be proportionately reduced, and, conversely, in case the outstanding
shares of Common Stock shall be combined into a smaller number of shares, the
Conversion Price in effect immediately prior to such combination shall be
proportionately increased.

          6G. Reorganization or Reclassification. If any capital reorganization
or reclassification of the capital stock of the Corporation shall be effected in
such a way that holders of Common Stock shall be entitled to receive stock,
securities or assets with respect to or in exchange for Common Stock, then, as a
condition of such reorganization or reclassification, lawful and adequate
provisions shall be made whereby each holder of a share or shares of Series A
Convertible Preferred Stock shall thereupon have the right to receive, upon the
basis and upon


                                       8
<PAGE>

the terms and conditions specified herein and in lieu of the shares of Common
Stock immediately theretofore receivable upon the conversion of such share or
shares of Series A Convertible Preferred Stock, such shares of stock, securities
or assets as may be issued or payable with respect to or in exchange for a
number of outstanding shares of such Common Stock equal to the number of shares
of such Common Stock immediately theretofore receivable upon such conversion had
such reorganization or reclassification not taken place, and in any such case
appropriate provisions shall be made with respect to the rights and interests of
such holder to the end that the provisions hereof (including without limitation
provisions for adjustments of the Conversion Price) shall thereafter be
applicable, as nearly as may be, in relation to any shares of stock, securities
or assets thereafter deliverable upon the exercise of such conversion rights.

          6H. Failure to Redeem. If the Corporation fails, for any reason or for
no reason, to redeem on the Redemption Date (as defined in paragraph 7) all of
the then outstanding shares of Series A Convertible Preferred Stock in
accordance with the terms and conditions of paragraph 7, the Conversion Price
then in effect shall be immediately reduced to an amount equal to 90% thereof.
Thereafter, until such redemption has been made in full in accordance with such
terms and conditions, the Conversion Price shall be further reduced on the 90th
day following the Redemption Date and at the end of each 90-day period
thereafter to an amount equal to 90% of the Conversion Price in effect
immediately prior to each such reduction.

          6I. Notice of Adjustment. Upon any adjustment of the Conversion Price,
then and in each such case the Corporation shall give written notice thereof, by
first class mail, postage prepaid, or by telex to non-U.S. residents, addressed
to each holder of shares of Series A Convertible Preferred Stock at the address
of such holder as shown on the books of the Corporation, which notice shall
state the Conversion Price resulting from such adjustment, setting forth in
reasonable detail the method upon which such calculation is based.

          6J. Other Notices. In case at any time:

                           (1) the Corporation shall declare any dividend upon
         its Common Stock payable in cash or stock or make any other
         distribution to the holders of its Common Stock;

                           (2) the Corporation shall offer for subscription pro
         rata to the holders of its Common Stock any additional shares of stock
         of any class or other rights;

                           (3) there shall be any capital reorganization or
         reclassification of the capital stock of the Corporation, or a
         consolidation or merger of the Corporation with or into, or a sale of
         all or substantially all of its assets to, another entity or entities;
         or

                  (4)  there shall be a voluntary or involuntary dissolution, 
         liquidation or winding up of the Corporation;

then, in any one or more of said cases, the Corporation shall give, by first
class mail, postage prepaid, or by telex to non-U.S. residents, addressed to
each holder of any shares of Series A


                                       9
<PAGE>

Convertible Preferred Stock at the address of such holder as shown on the books
of the Corporation, (a) at least 20 days' prior written notice of the date on
which the books of the Corporation shall close or a record shall be taken for
such dividend, distribution or subscription rights or for determining rights to
vote in respect of any such reorganization, reclassification, consolidation,
merger, sale, dissolution, liquidation or winding up and (b) in the case of any
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding up, at least 20 days' prior written notice of the date
when the same shall take place. Such notice in accordance with the foregoing
clause (a) shall also specify, in the case of any such dividend, distribution or
subscription rights, the date on which the holders of Common Stock shall be
entitled thereto and such notice in accordance with the foregoing clause (b)
shall also specify the date on which the holders of Common Stock shall be
entitled to exchange their Common Stock for securities or other property
deliverable upon such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding up, as the case may be.

          6K. Stock to be Reserved. The Corporation will at all times reserve
and keep available out of its authorized Common Stock, solely for the purpose of
issuance upon the conversion of Series A Convertible Preferred Stock as herein
provided, such number of shares of Common Stock as shall then be issuable upon
the conversion of all outstanding shares of Series A Convertible Preferred
Stock. The Corporation covenants that all shares of Common Stock which shall be
so issued shall be duly and validly issued and fully paid and nonassessable and
free from all taxes, liens and charges with respect to the issue thereof, and,
without limiting the generality of the foregoing, the Corporation covenants that
it will from time to time take all such action as may be requisite to assure
that the par value per share of the Common Stock is at all times equal to or
less than the Conversion Price in effect at the time. The Corporation will take
all such action as may be necessary to assure that all such shares of Common
Stock may be so issued without violation of any applicable law or regulation, or
of any requirement of any national securities exchange upon which the Common
Stock may be listed. The Corporation will not take any action which results in
any adjustment of the Conversion Price if the total number of shares of Common
Stock issued and issuable after such action upon conversion of the Series A
Convertible Preferred Stock would exceed the total number of shares of Common
Stock then authorized by the Restated Certificate of Incorporation.

          6L. No Reissuance of Series A Convertible Preferred Stock. Shares of
Series A Convertible Preferred Stock which are converted into shares of Common
Stock as provided herein shall not be reissued.

          6M. Issue Tax. The issuance of certificates for shares of Common Stock
upon conversion of Series A Convertible Preferred Stock shall be made without
charge to the holders thereof for any issuance tax in respect thereof, provided
that the Corporation shall not be required to pay any tax which may be payable
in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than that of the holder of the Series A Convertible
Preferred Stock which is being converted.

          6N. Closing of Books. The Corporation will at no time close its
transfer books against the transfer of any Series A Convertible Preferred Stock
or of any shares of Common



                                       10
<PAGE>

Stock issued or issuable upon the conversion of any shares of Series A
Convertible Preferred Stock in any manner which interferes with the timely
conversion of such Series A Convertible Preferred Stock, except as may otherwise
be required to comply with applicable securities laws.

          6O. Definition of Common Stock. As used in this paragraph 6, the term
"Common Stock" shall mean and include the Corporation's authorized Common Stock,
par value $.01 per share, as constituted on the date of filing of these terms of
the Series A Convertible Preferred Stock, and shall also include any capital
stock of any class of the Corporation thereafter authorized which shall not be
limited to a fixed sum or percentage of par value in respect of the rights of
the holders thereof to participate in dividends or in the distribution of assets
upon the voluntary or involuntary liquidation, dissolution or winding up of the
Corporation; provided that the shares of Common Stock receivable upon conversion
of shares of Series A Convertible Preferred Stock shall include only shares
designated as Common Stock of the Corporation on the date of filing of this
instrument, or in case of any reorganization or reclassification of the
outstanding shares thereof, the stock, securities or assets provided for in
subparagraph 6G.

          6P. Mandatory Conversion. If at any time the Corporation shall effect
a firm commitment underwritten public offering of shares of Common Stock in
which (i) the aggregate price paid for such shares by the public shall be at
least $5,000,000 and (ii) the price paid by the public for such shares shall be
at lest $10.50 per share (appropriately adjusted to reflect the occurrence of
any event described in subparagraph 6F), then effective upon the closing of the
sale of such shares by the Corporation pursuant to such public offering, all
outstanding shares of Series A Convertible Preferred Stock shall automatically
convert to shares of Common Stock.

           7.  Redemption.  The shares of Series A Convertible Preferred Stock 
shall be redeemed as follows:

                  7A. Mandatory Redemption. On December 31, 1995, the
Corporation shall redeem from each holder of shares of Series A Preferred Stock,
all of the shares of Series A Convertible Preferred Stock held by such holder on
the Redemption Date.

                  7B. Optional Redemption. At any time after December 31, 1992,
the Corporation shall have the right, at its sole option, to redeem from each
holder of shares of Series A Convertible Preferred stock, all of the shares of
Series A Convertible Preferred Stock held by such holder on the date of such
redemption. The date of a redemption pursuant to Section 7A or 7B is hereinafter
referred to as the "Redemption Date."

                  7C. Redemption Price and Payment. The Series A Convertible
Preferred Stock to be redeemed on the Redemption Date shall be redeemed by
paying for each share in cash an amount equal to $3.00 per share plus, in the
case of each share, an amount equal to all Accruing Dividends unpaid thereon
(whether or not declared) and any other dividends declared but unpaid thereon,
computed to the Redemption Date, such amount being referred to as the
"Redemption Price." Such payment shall be made in full on the Redemption Date to
the holders entitled thereto.



                                       11
<PAGE>

          7D. Redemption Mechanics. At least 20, but not more than 30 days prior
to the Redemption Date, written notice (the "Redemption Notice") shall be given
by the Corporation by mail, postage prepaid, or by telex to non-U.S. residents
to each holder of record (at the close of business on the business day next
preceding the day on which the Redemption Notice is given) of shares of Series A
Convertible Preferred Stock notifying such holder of the redemption and
specifying the Redemption Price, the Redemption Date and the place where said
Redemption Price shall be payable. The Redemption Notice shall be addressed to
each holder at his address as shown by the records of the Corporation. From and
after the close of business on the Redemption Date, unless there shall have been
a default in the payment of the Redemption Price, all rights of holders of
shares of Series A Convertible Preferred Stock (except the right to receive the
Redemption Price) shall cease with respect to such shares, and such shares shall
not thereafter be transferred on the books of the Corporation or be deemed to be
outstanding for any purpose whatsoever. If the funds of the Corporation legally
available for redemption of shares of Series A Convertible Preferred Stock on
the Redemption Date are insufficient to redeem the total number of outstanding
shares of Series A Convertible Preferred Stock, the holders of shares of Series
A Convertible Preferred Stock shall share ratably in any funds legally available
for redemption of such shares according to the respective amounts which would be
payable with respect to the full number of shares owned by them if all such
outstanding shares were redeemed in full. The shares of Series A Convertible
Preferred Stock not redeemed shall remain outstanding and entitled to all rights
and preferences provided herein. At any time thereafter, when additional funds
of the Corporation are legally available for the redemption of such shares of
Series A Convertible Preferred Stock, such funds will be used, at the end of the
next succeeding fiscal quarter, to redeem the balance of such shares, or such
portion thereof for which funds are then legally available, on the basis set
forth above.

          7E. Redeemed or Otherwise Acquired Shares to be Retired. Any shares of
Series A Convertible Preferred Stock redeemed pursuant to this paragraph 7 or
otherwise acquired by the Corporation in any manner whatsoever shall be
cancelled and shall not under any circumstances be reissued; and the Corporation
may from time to time take such appropriate corporation action as may be
necessary to reduce accordingly the number of authorized shares of Series A
Convertible Preferred Stock.

          8. Amendments. No provision of these terms of the Series A Convertible
Preferred Stock may be amended, modified or waived without the written consent
or affirmative vote of the holders of at least two-thirds of the then
outstanding shares of Series A Convertible Preferred Stock."

          (4) The foregoing amendment to the Certificate of Incorporation was
authorized by the Board of Directors at a meeting of the Board duly held on
December 12, 1989.

                  (ii) The rate per annum and the times at and conditions upon
which the holders of stock of such series shall be entitled to receive
dividends, and whether such dividends shall be cumulative or non-cumulative and
if cumulative the terms upon which such dividends shall be cumulative;

                  (iii) The price or prices and the time or times at and
the manner in which the stock of such series shall be redeemable;

                  (iv) The rights to which the holders of the shares of stock of
such series shall be entitled upon any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation;

                  (v) The terms, if any, upon which the shares of stock of such
series shall be convertible into, or exchangeable for, shares of stock of any
other class or classes or of any other series of the same or any other class or
classes, including the price or prices or the rate or rates of conversion or
exchange and the terms of adjustment, if any; and



                                       2
<PAGE>

                  (vi) Any other designations, preferences and relative,
participating, optional or other special rights, and qualifications, limitations
or restrictions thereof so far as they are not inconsistent with the provisions
of the Certificate of Incorporation, as amended, and to the full extent now or
hereafter permitted by the laws of the State of New York.

      All shares of the Preferred Stock of any one series shall be identical to
each other in all aspects, except that shares of any one series issued at
different times may differ as to the dates from which dividends thereof, if
cumulative, shall be cumulative.

            (b)   Number of Shares.

                  (i) The Series A Convertible Preferred Stock authorized
pursuant to the Certificate of Amendment filed January 4, 1990 consisting of
800,000 issued shares and 200,000 unissued shares is eliminated pursuant to the
written consent of 93.75% of the outstanding Series A Convertible Preferred
Stock.

                  (ii) One Million (1,000,000) shares of authorized Preferred
Stock of the par value of $.01 each shall be issued in and as a series to be
designated "Series B Convertible Preferred Stock."

                  (iii) 1,542,000 shares of authorized Preferred Stock of the
par value of $.01 each shall be issued in and as a series to be designated
"Series C Convertible Preferred Stock."

                  (iv) The term Preferred Stock, as used herein, shall include
all of the shares of Preferred Stock authorized by the Board of Directors
pursuant to the Certificate of Incorporation, including the Series B Convertible
Preferred Stock and Series C Convertible Preferred Stock.

            (c)   Voting.

                  (i) General. Except as may be otherwise provided in these
terms of the Series B and Series C Convertible Preferred Stock or by law, the
Series B and Series C Convertible Preferred Stock shall vote together with all
other classes and series of stock of the Corporation as a single class on all
actions to be taken by the shareholders of the Corporation. Each share of Series
B and Series C Convertible Preferred Stock shall entitle the holder thereof to
such number of votes per share on each such action as shall equal the number of
shares of Common Stock (including fractions of a share) into which each share of
Series B and Series C Convertible Preferred Stock is then convertible.

                  (ii)  Board Size.  The Corporation shall not, without the
written consent or affirmative vote of the holders of at least two-thirds
of the then outstanding shares of Series B and Series C Convertible
Preferred Stock, given in writing or by vote


                                       3
<PAGE>

at a meeting, consenting or voting (as the case may be) together as a single
series, increase the maximum number of directors constituting the Board of
Directors to a number in excess of six (6).

                  (iii) Board Seats. The holders of the Series B and Series C
Convertible Preferred Stock voting together as a single series, shall be
entitled to elect three (3) directors of the Corporation. The holders of the
Common Stock, voting as a separate class, shall be entitled to elect the
remaining directors of the Corporation. Notwithstanding the foregoing or
anything else to the contrary provided in the Restated Certificate of
Incorporation, if the Corporation fails or refuses, for any reason or for no
reason, to redeem on the Redemption Date (as defined in paragraph (h)) all of
the then outstanding shares of Series B Preferred Stock in accordance with the
terms and provisions of paragraph (h), the holders of the Series B Convertible
Preferred Stock, voting as a separate series, shall be entitled to elect a
majority of the directors of the Corporation. At any meeting (or in a written
consent in lieu thereof) held for the purpose of electing directors, the
presence in person or by proxy (or the written consent) of the holders of a
majority of the shares of Series B and Series C Convertible Preferred Stock then
outstanding shall constitute a quorum of the Series B and Series C Convertible
Preferred Stock for the election of directors to be elected solely by the
holders of the Series B and Series C Convertible Preferred Stock. A vacancy in
any directorship elected by the holders of the Series B and Series C Convertible
Preferred Stock shall be filled only by vote or written consent of the holders
of the Series B and Series C Convertible Preferred Stock.

            (d)   Dividends.

                  (i) The holders of the Series B Convertible Preferred Stock
shall be entitled to receive, out of funds legally available therefor, when and
if declared by the Board of Directors, quarterly dividends at the rate per annum
of Eight (8%) percent per share. The dividends may be paid in cash or accrued at
the option of the Corporation. If not paid in cash the dividends (the "Accruing
Dividends") shall accrue from day to day, whether or not earned or declared, and
shall be cumulative from the date of issuance of the Series B Convertible
Preferred Stock and shall be added to the face amount of the Series B
Convertible Preferred Stock at the rate of $2.00 per share or such price
adjusted pursuant to the provisions of paragraph (g)(iv) hereof at the time of
conversion.

                  (ii) There are no dividends payable or accrued on the Series C
Convertible Preferred Stock.

            (e) Liquidation. Upon any liquidation, dissolution or winding up of
the Corporation, whether voluntary or involuntary, the holders of the shares of
Series B Convertible Preferred Stock shall first be entitled, before any
distribution or payment is made upon any stock ranking on liquidation junior to
the Series B and Series C Convertible Preferred Stock, to be paid an amount
equal to $2.00 per share plus, in the 


                                       4
<PAGE>

case of each share, an amount equal to all Accruing Dividends unpaid thereon
(whether or not declared) and any other dividends declared but unpaid thereon,
computed to the date payment thereof is made available, such amount payable with
respect to one share of Series B Convertible Preferred Stock being sometimes
referred to as the "Series B Liquidation Preference Payment." Upon any
liquidation, dissolution or winding up of the Corporation, whether voluntary or
involuntary, the holders of the shares of Series C Convertible Preferred Stock
shall first be entitled, before any distribution or payment is made upon any
stock ranking on liquidation junior to the Series C Convertible Preferred Stock,
to be paid an amount equal to $1.00 per share, such amount payable with respect
to one share of Series C Preferred Stock being sometimes referred to as the
"Series C Liquidation Preference Payment." If upon such liquidation, dissolution
or winding up of the Corporation, whether voluntary or involuntary, the assets
to be distributed among the holders of Series B and Series C Convertible
Preferred Stock shall be insufficient to permit payment in full to the holders
of Series B and Series C Convertible Preferred Stock of the Liquidation
Preference Payments, then the entire assets of the Corporation to be so
distributed shall be distributed ratably among the holders of Series B and
Series C Convertible Preferred Stock. Upon any such liquidation, dissolution or
winding up of the Corporation, immediately after the holders of Series B and
Series C Convertible Preferred Stock shall have been paid in full the Series B
and Series C Convertible Liquidation Preference Payments, the remaining net
assets of the Corporation available for distribution shall be distributed
ratably among the holders of Series B and Series C Convertible Preferred Stock
and Common Stock (with each share of Series B and Series C Convertible Preferred
Stock being deemed, for such purpose, to be equal to the number of shares of
Common Stock (including fractions of a share) into which such share of Series B
and Series C Convertible Preferred Stock is convertible immediately prior to the
close of business on the business day fixed for such distribution). Written
notice of such liquidation, dissolution or winding up, stating a payment date
and the place where said payment shall be made, shall be given by mail, postage
prepaid, or by telex to non-U.S. residents, not less than 20 days prior to the
payment date stated therein, to the holders of record of Series B and Series C
Convertible Preferred Stock, such notice to be addressed to each such holder at
its address as shown by the records of the Corporation. The consolidation or
merger of the Corporation into or with any other entity or entities which
results in the exchange of outstanding shares of the Corporation for securities
or other consideration issued or paid or caused to be issued or paid by any such
entity or affiliate thereof, and the sale or transfer by the Corporation of all
or substantially all its assets, shall be deemed to be a liquidation,
dissolution or winding up of the Corporation within the meaning of the
provisions of this paragraph (e). For purposes hereof, the Common Stock shall
rank on liquidation junior to the Series B and Series C Convertible Preferred
Stock.

            (f) Restrictions. At any time when shares of Series B and Series C
Convertible Preferred Stock are outstanding, except where the vote or written
consent of the holders of a greater number of shares of the Corporation is
required by law or by the Restated Certificate of Incorporation, and in addition
to any other vote required by law or the Restated Certificate of Incorporation,
as amended, without the approval of the holders 


                                       5
<PAGE>
of at least two-thirds of the then outstanding shares of Series B and Series C
Convertible Preferred Stock, given in writing or by vote at a meeting,
consenting or voting (as the case may be) separately as a series, the
Corporation will not:

                  (i) Create or authorize the creation of any additional class
or series of shares of stock unless the same ranks junior to the Series B and
Series C Convertible Preferred Stock as to the distribution of assets on the
liquidation, dissolution or winding up of the Corporation, or increase the
authorized amount of the Series B and Series C Convertible Preferred Stock or
increase the authorized amount of any additional class or series of shares of
stock unless the same ranks junior to the Series B and Series C Convertible
Preferred Stock as to the distribution of assets on the liquidation, dissolution
or winding up of the Corporation, or create or authorize any obligation or
security convertible into shares of Series B and Series C Convertible Preferred
Stock or into shares of any other class or series of stock unless the same ranks
junior to the Series B and Series C Convertible Preferred Stock as to the
distribution of assets on the liquidation, dissolution or winding up of the
Corporation, whether any such creation, authorization or increase shall be by
means of amendment to the Restated Certificate of Incorporation or by merger,
consolidation or otherwise;

                  (ii) Consent to any liquidation, dissolution or winding up of
the Corporation or consolidate or merge into or with any other entity or
entities or sell or transfer all or substantially all its assets;

                  (iii) Amend, alter or repeal its Restated Certificate of
Incorporation or By-laws in a manner which adversely affects the holders of
Series B and Series C Convertible Preferred Stock;

                  (iv) Purchase or set aside any sums for the purchase of, or
pay any dividend or make any distribution on, any shares of stock other than the
Series B Convertible Preferred Stock, except for dividends or other
distributions payable on the Common Stock solely in the form of additional
shares of Common Stock and except for the purchase of shares of Common Stock
from former employees of the Corporation who acquired such shares directly from
the Corporation, if each such purchase is made pursuant to contractual rights
held by the Corporation relating to the termination of employment of such former
employee and the purchase price does not exceed the original issue price paid by
such former employee to the Corporation for such shares; or

                  (v) Redeem or otherwise acquire any shares of Series B
Convertible Preferred Stock except as expressly authorized in paragraph (h)
hereof or pursuant to a purchase offer made pro rata to all holders of the
shares of Series B Convertible Preferred Stock on the basis of the aggregate
number of outstanding shares of Series B Convertible Preferred Stock then held
by each such holder.

            (g) Conversions. The holders of shares of Series B and Series C
Convertible Preferred Stock shall have the following conversion rights:



                                       6
<PAGE>

                  (i)(1) Right to Convert Series B Convertible Preferred Stock.
Subject to the terms and conditions of this paragraph (g), the holder of any
share or shares of Series B Convertible Preferred Stock shall have the right, at
its option at any time prior to December 30, 1999 to convert any such shares of
Series B Convertible Preferred Stock (except that upon any liquidation of the
Corporation the right of conversion shall terminate at the close of business on
the business day fixed for payment of the amount distributable on the Series B
Convertible Preferred Stock) into such number of fully paid and nonassessable
shares of Common Stock as is obtained by (i) multiplying the number of shares of
Series B Convertible Preferred Stock so to be converted by $2.00 and adding an
amount equal to all Accruing Dividends unpaid thereon (whether or not declared)
and any other dividends declared but unpaid thereon, computed to the date of
conversion and (ii) dividing the result by the conversion price of $2.00 per
share or, in case an adjustment of such price has taken place pursuant to the
further provisions of this paragraph (g), then by the conversion price as last
adjusted and in effect at the date any share or shares of Series B Convertible
Preferred Stock are surrendered for conversion (such price, or such price as
last adjusted, being referred to as the "Conversion Price"). Such rights of
conversion shall be exercised by the holder thereof by giving written notice
that the holder elects to convert a stated number of shares of Series B
Convertible Preferred Stock into Common Stock and by surrender of a certificate
or certificates for the shares so to be converted to the Corporation at its
principal office (or such other office or agency of the Corporation as the
Corporation may designate by notice in writing to the holders of the Series B
Convertible Preferred Stock) at any time during its usual business hours on the
date set forth in such notice, together with a statement of the name or names
(with address) in which the certificate or certificates for shares of Common
Stock shall be issued.

                  (i)(2). Right to Convert Series C Convertible Preferred Stock.
Subject to the terms and conditions of this paragraph (g), the holder of any
share or shares of Series C Convertible Preferred Stock shall have the right, at
its option at any time prior to December 30, 2004 to convert any such shares of
Series C Convertible Preferred Stock (except that upon any liquidation of the
Corporation the right of conversion shall terminate at the close of business on
the business day fixed for payment of the amount distributable on the Series C
Convertible Preferred Stock) into such number of fully paid and nonassessable
shares of Common Stock as is obtained by (i) multiplying the number of shares of
Series C Convertible Preferred Stock so to be converted by $1.00 and (ii)
dividing the result by the conversion price of $1.00 per share or, in case an
adjustment of such price has taken place pursuant to the further provisions of
this paragraph (g), then by the conversion price as last adjusted and in effect
at the date any share or shares of Series C Convertible Preferred Stock are
surrendered for conversion (such price, or such price as last adjusted, being
referred to as the "Conversion Price"). Such rights of conversion shall be
exercised by the holder thereof by giving written notice that the holder elects
to convert a stated number of shares of Series C Convertible Preferred Stock
into Common Stock and by surrender of a certificate or certificates for the
shares so to be converted to the Corporation at its principal office (or such
other office or agency of the Corporation 


                                       7
<PAGE>

as the Corporation may designate by notice in writing to the holders of the
Series C Convertible Preferred Stock) at any time during its usual business
hours on the date set forth in such notice, together with a statement of the
name or names (with address) in which the certificate or certificates for shares
of Common Stock shall be issued.

                  (ii) Issuance of Certificates; Time Conversion Effected.
Promptly after the receipt of the written notice referred to in subparagraph
(g)(i)(1) and/or (g)(i)(2) and the surrender of the certificate or certificates
for the share or shares of Series B and/or Series C Convertible Preferred Stock
to be converted, the Corporation shall issue and deliver, or cause to be issued
and delivered, to the holder, registered in such name or names as such holder
may direct, a certificate or certificates for the number of whole shares of
Common Stock issuable upon the conversion of such share or shares of Series B
and/or Series C Convertible Preferred Stock. To the extent permitted by law,
such conversion shall be deemed to have been effected and the Conversion Price
shall be determined as of the close of business on the date on which such
written notice shall have been received by the Corporation and the certificate
or certificates for such share or shares shall have been surrendered as
aforesaid, and at such time the rights of the holder of such share or shares of
Series B and/or Series C Preferred Stock shall cease, and the person or persons
in whose name or names any certificate or certificates for shares of Common
Stock shall be issuable upon such conversion shall be deemed to have become the
holder or holders of record of the shares represented thereby.

                  (iii) Fractional Shares; Dividends; Partial Conversion. No
fractional shares shall be issued upon conversion of Series B and Series C
Convertible Preferred Stock into Common Stock and no payment or adjustment shall
be made upon any conversion on account of any cash dividends on the Common Stock
issued upon such conversion. In case the number of shares of Series B and Series
C Convertible Preferred Stock represented by the certificate or certificates
surrendered pursuant to subparagraph (g)(i) exceeds the number of shares
converted, the Corporation shall, upon such conversion, execute and deliver to
the holder, at the expense of the Corporation, a new certificate or certificates
for the number of shares of Series B or Series C Convertible Preferred Stock
represented by the certificate or certificates surrendered which are not to be
converted. If any fractional share of Common Stock would, except for the
provisions of the first sentence of this subparagraph (g)(ii), be delivered upon
such conversion, the Corporation, in lieu of delivering such fractional share,
shall pay to the holder surrendering the Series B and Series C Convertible
Preferred Stock for conversion an amount in cash equal to the current market
price of such fractional share as determined in good faith by the Board of
Directors of the Corporation.

                  (iv) Adjustment of Price Upon Issuance of Common Stock. Except
as provided in subparagraph (g)(vi), if and whenever the Corporation shall issue
or sell, or is, in accordance with subparagraphs (g)(v)(1) through (g)(v)(7),
deemed to have issued or sold, any share of Common Stock for a consideration per
share less than the Conversion Price in effect immediately prior to the time of
such issue or sale, then, forthwith upon such issue or sale, the Conversion
Price shall be reduced to the price at


                                       8
<PAGE>

which the Corporation issued or sold, or is deemed to have issued or sold, such
shares of Common Stock.

      For purposes of this subparagraph (g)(iv), the following subparagraphs
(g)(v)(1) to (g)(v)(7) shall also be applicable:

                  (v)(1). Issuance of Rights or Options. In case at any time the
Corporation shall in any manner grant (whether directly or by assumption in a
merger or otherwise) any warrants or other rights to subscribe for or to
purchase, or any options for the purchase of, Common Stock or any stock or
security convertible into or exchangeable for Common Stock (such warrants,
rights or options being called "Options" and such convertible or exchangeable
stock or securities being called "Convertible Securities") whether or not such
Options or the right to convert or exchange any such Convertible Securities are
immediately exercisable, and the price per share for which Common Stock is
issuable upon the exercise of such Options or upon the conversion or exchange of
such Convertible Securities (determined by dividing (i) the total amount, if
any, received or receivable by the Corporation as consideration for the granting
of such Options, plus the minimum aggregate amount of additional consideration
payable to the Corporation upon the exercise of all such Options, plus, in the
case of such Options which relate to Convertible Securities, the minimum
aggregate amount of additional consideration, if any, payable upon the issue or
sale of such Convertible Securities and upon the conversion or exchange thereof,
by (ii) the total maximum number of shares of Common Stock issuable upon the
exercise of such Options or upon the conversion or exchange of all such
Convertible Securities issuable upon the exercise of such Options) shall be less
than the Conversion Price in effect immediately prior to the time of the
granting of such Options, then the total maximum number of shares of Common
Stock issuable upon the exercise of such Options or upon conversion or exchange
of the total maximum amount of such Convertible Securities issuable upon the
exercise of such Options shall be deemed to have been issued for such price per
share as of the date of granting of such Options or the issuance of such
Convertible Securities and thereafter shall be deemed to be outstanding. Except
as otherwise provided in subparagraph (g)(v)(3), no adjustment of the Conversion
Price shall be made upon the actual issue of such Common Stock or of such
Convertible Securities upon exercise of such Options or upon the actual issue of
such Common Stock upon conversion or exchange of such Convertible Securities.

                  (v)(2). Issuance of Convertible Securities. In case the
Corporation shall in any manner issue (whether directly or by assumption in a
merger or otherwise) or sell any Convertible Securities, whether or not the
rights to exchange or convert any such Convertible Securities are immediately
exercisable, and the price per share for which Common Stock is issuable upon
such conversion or exchange (determined by dividing (i) the total amount
received or receivable by the Corporation as consideration for the issue or sale
of such Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Corporation upon the conversion or
exchange thereof, by (ii) the total/maximum number of shares of Common Stock
issuable upon the conversion or exchange of all such Convertible Securities)
shall be less than the



                                       9
<PAGE>

Conversion Price in effect immediately prior to the time of such issue or sale,
then the total maximum number of shares of Common Stock issuable upon conversion
or exchange of all such Convertible Securities shall be deemed to have been
issued for such price per share as of the date of the issue or sale of such
Convertible Securities and thereafter shall be deemed to be outstanding,
provided that (a) except as otherwise provided in subparagraph (g)(v)(3), no
adjustment of the Conversion Price shall be made upon the actual issue of such
Common Stock upon conversion or exchange of such Convertible Securities and (b)
if any such issue or sale of such Convertible Securities is made upon exercise
of any Options to purchase any such Convertible Securities for which adjustments
of the Conversion Price have been or are to be made pursuant to other provisions
of this subparagraph (g)(3), no further adjustment of the Conversion Price shall
be made by reason of such issue or sale.

                  (v)(3) Change in Option Price or Conversion Rate. Upon the
happening of any of the following events, namely, if the purchase price provided
for in any Option referred to in subparagraph (g)(v)(1), the additional
consideration, if any, payable upon the conversion or exchange of any
Convertible Securities referred to in subparagraph (g)(v)(1) or (g)(v)(2), or
the rate at which Convertible Securities referred to in subparagraph (g)(v)(1)
or (g)(v)(2) are convertible into or exchangeable for Common Stock shall change
at any time (including, but not limited to, changes under or by reason of
provisions designed to protect against dilution), the Conversion Price in effect
at the time of such event shall forthwith be readjusted to the Conversion Price
which would have been in effect at such time had such Options or Convertible
Securities still outstanding provided for such changed purchase price,
additional consideration or conversion rate, as the case may be, at the time
initially granted, issued or sold, but only if as a result of such adjustment
the Conversion Price then in effect hereunder is thereby reduced; and on the
expiration of any such Option for the termination of any such right to convert
or exchange such Convertible Securities, the Conversion Price then in effect
hereunder shall forthwith be increased to the Conversion Price which would have
been in effect at the time of such expiration or termination had such Option or
Convertible Securities, to the extent outstanding immediately prior to such
expiration or termination, never been issued.

                  (v)(4) Stock Dividends. In case the Corporation shall declare
a dividend or make any other distribution upon any stock of the Corporation
payable in Common Stock (except for dividends or distributions upon the Common
Stock), Options or Convertible Securities, any Common Stock, Options or
Convertible Securities, as the case may be, issuable in payment of such dividend
or distribution shall be deemed to have been issued or sold without
consideration.

                  (v)(5) Consideration for Stock. In case any shares of Common
Stock, Options or Convertible Securities shall be issued or sold for cash, the
consideration received therefor shall be deemed to be the amount received by the
Corporation therefor, without deduction therefrom of any expenses incurred or
any underwriting commissions or concessions paid or allowed by the Corporation
in


                                       10
<PAGE>

connection therewith. In case any shares of Common Stock, Options or Convertible
Securities shall be issued or sold for a consideration other than cash, the
amount of the consideration other than cash received by the Corporation shall be
deemed to be the fair value of such consideration as determined in good faith by
the Board of Directors of the Corporation, without deduction of any expenses
incurred or any underwriting commissions or concessions paid or allowed by the
Corporation in connection therewith. In case any Options shall be issued in
connection with the issue and sale of other securities of the Corporation,
together comprising one integral transaction in which no specific consideration
is allocated to such Options by the parties thereto, such Options shall be
deemed to have been issued for such consideration as determined in good faith by
the Board of Directors of the Corporation.

                  (v)(6) Record Date. In case the Corporation shall take a
record of the holders of its Common Stock for the purpose of entitling them (i)
to receive a dividend or other distribution payable in Common Stock, Options or
Convertible Securities, then such record date shall be deemed to be the date of
the issue or sale of the shares of Common Stock deemed to have been issued or
sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                  (v)(7)      Treasury Shares.  The disposition of any
shares of Common Stock owned or held by or for the account of the
Corporation shall be considered an issue or sale of Common Stock for the
purpose of this subparagraph (g)(iv).

                  (vi) Certain Issues of Common Stock Excepted. Anything herein
to the contrary notwithstanding, the Corporation shall not be required to make
any adjustment of the Conversion Price in the case of the issuance of up to an
aggregate of 1,000,000 shares (appropriately adjusted to reflect the occurrence
of any event described in subparagraph (g)(viii) of Common Stock to officers,
directors, consultants or employees of the Corporation in connection with their
employment by the Corporation, the issuance of 1,542,000 shares of Series C
Convertible Preferred Stock with a conversion price of $1.00 per share and the
issuance of warrants to purchase 80,000 shares of common stock of the
Corporation at a price of $1.00 per share.

                  (vii) Subdivision or Combination of Common Stock. In case the
Corporation shall at any time subdivide (by any stock split, stock dividend or
otherwise) its outstanding shares of Common Stock into a greater number of
shares, the conversion Price in effect immediately prior to such subdivision
shall be proportionately reduced, and, conversely, in case the outstanding
shares of Common Stock shall be combined into a smaller number of shares, the
Conversion Price in effect immediately prior to such combination shall be
proportionately increased.

                  (viii)      Reorganization or Reclassification.  If any
capital reorganization or reclassification of the capital stock of the
Corporation shall be effected in such a way that holders of Common Stock
shall be entitled to receive stock, securities


                                       11
<PAGE>

or assets with respect to or in exchange for Common Stock, then, as a condition
of such reorganization or reclassification, lawful and adequate provisions shall
be made whereby each holder of a share or shares of Series B and Series C
Convertible Preferred Stock shall thereupon have the right to receive, upon the
basis and upon the terms and conditions specified herein and in lieu of the
shares of Common Stock immediately theretofore receivable upon the conversion of
such share or shares of Series B and Series C Convertible Preferred Stock, such
shares of stock, securities or assets as may be issued or payable with respect
to or in exchange for a number of outstanding shares of such Common Stock equal
to the number of shares of such Common Stock immediately theretofore receivable
upon such conversion had such reorganization or reclassification not taken
place, and in any such case appropriate provisions shall be made with respect to
the rights and interests of such holder to the end that the provisions hereof
(including without limitation provisions for adjustments of the Conversion
Price) shall thereafter be applicable, as nearly as may be, in relation to any
shares of stock, securities or assets thereafter deliverable upon the exercise
of such conversion rights.

                  (ix) Failure to Redeem. If the Corporation fails, for any
reason or for no reason, to redeem on the Redemption Date (as defined in
paragraph (h) all of the then outstanding shares of Series B Convertible
Preferred Stock in accordance with the terms and conditions of paragraph (h),
the Conversion Price then in effect shall be immediately reduced to an amount
equal to 90% thereof. Thereafter, until such redemption has been made in full in
accordance with such terms and conditions, the Conversion Price shall be further
reduced on the 90th day following the Redemption Date and at the end of each
90-day period thereafter to an amount equal to 90% of the Conversion Price in
effect immediately prior to each such reduction.

                  (x) Notice of Adjustment. Upon any adjustment of the
Conversion Price, then and in each such case the Corporation shall give written
notice thereof, by first class mail, postage prepaid, or by telex to non-U.S.
residents, addressed to each holder of shares of Series B and Series C
Convertible Preferred Stock at the address of such holder as shown on the books
of the Corporation, which notice shall state the conversion Price resulting from
such adjustment, setting forth in reasonable detail the method upon which such
calculation is based.

                  (xi)  Other Notices.  In case at any time:

                        (xi)(1) the Corporation shall declare any dividend
upon its Common Stock payable in cash or stock or make any other
distribution to the holders of its Common Stock;

                        (xi)(2) the Corporation shall offer for subscription

                                       12
<PAGE>

                        (xi)(3) there shall be any capital reorganization or
reclassification of the capital stock of the Corporation, or a consolidation or
merger of the Corporation with or into, or a sale of all or substantially all
its assets to, another entity or entities; or

                  (4)   there shall be a voluntary or involuntary
dissolution, liquidation or winding up of the Corporation;

then, in any one or more of said cases, the Corporation shall give, by first
class mail, postage prepaid, or by telex to non-U.S. residents, addressed to
each holder of any shares of Series B and Series C Convertible Preferred Stock
at the address of such holder as shown on the books of the Corporation, (a) at
least 20 days' prior written notice of the date on which the books of the
Corporation shall close or a record shall be taken for such dividend,
distribution or subscription rights or for determining rights to vote in respect
of any such reorganization, reclassification, consolidation, merger, sale,
dissolution, liquidation or winding up and (b) in the case of any such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding up, at least 20 days' prior written notice of the date
when the same shall take place. Such notice in accordance with the foregoing
clause (a) shall also specify, in the case of any such dividend, distribution or
subscription rights, the date on which the holders of Common Stock shall be
entitled thereto and such notice in accordance with the foregoing clause (b)
shall also specify the date on which the holders of Common Stock shall be
entitled to exchange their Common Stock for securities or other property
deliverable upon such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding up, as the case may be.

                  (xii) Stock to be Reserved. The Corporation will at all times
reserve and keep available out of its authorized Common Stock, solely for the
purpose of issuance upon the conversion of Series B and/or Series C Convertible
Preferred Stock as herein provided, such number of shares of Common Stock as
shall then be issuable upon the conversion of all outstanding shares of Series B
and/or Series C Convertible Preferred Stock. The Corporation covenants that all
shares of Common Stock which shall be so issued shall be duly and validly issued
and fully paid and nonassessable and free from all taxes, liens and charges with
respect to the issue thereof, and, without limiting the generality of the
foregoing, the Corporation covenants that it will from time to time take all
such action as may be requisite to assure that the par value per share of the
Common Stock is at all times equal to or less than the Conversion Price in
effect at the time. The Corporation will take all such action as may be
necessary to assure that all such shares of Common Stock may be so issued
without violation of any applicable law or regulation, or of any requirement of
any national securities exchange upon which the Common Stock may be listed. The
Corporation will not take any action which results in any adjustment of the
Conversion Price if the total number of shares of Common Stock issued and
issuable after such action upon conversion of the Series B and/or Series C
Convertible Preferred Stock would exceed the total number of shares of Common
Stock then authorized by the Restated Certificate of Incorporation, as amended.



                                       13
<PAGE>

                  (xiii) No Reissuance of Series B or Series C Convertible
Preferred Stock. Shares of Series B and/or Series C Convertible Preferred Stock
which are converted into shares of Common Stock as provided herein shall not be
reissued.

                  (xiv) Issue Tax. The issuance of certificates for shares of
Common Stock upon conversion of Series B and/or Series C Convertible Preferred
Stock shall be made without charge to the holders thereof for any issuance tax
in respect thereof, provided that the Corporation shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issuance
and delivery of any certificate in a name other than that of the holder of the
Series B and/or Series C Convertible Preferred Stock which is being converted.

                  (xv) Closing of Books. The Corporation will at no time close
its transfer books against the transfer of any Series B and/or Series C
Convertible Preferred Stock or of any shares of Common Stock issued or issuable
upon the conversion of any shares of Series B and/or Series C Convertible
Preferred Stock in any manner which interferes with the timely conversion of
such Series B and Series C Convertible Preferred Stock, except as may otherwise
be required to comply with applicable securities laws.

                  (xvi) Definition of Common Stock. As used in this paragraph
(g), the term "Common Stock" shall mean and include the Corporation's authorized
Common Stock, par value $.01 per share, as constituted on the date of filing of
these terms of the Series B and Series C Convertible Preferred Stock, and shall
also include any capital stock of any class of the Corporation thereafter
authorized which shall not be limited to a fixed sum or percentage of par value
in respect of the rights of the holders thereof to participate in dividends or
in the distribution of assets upon the voluntary or involuntary liquidation,
dissolution or winding up of the Corporation; provided that the shares of Common
Stock receivable upon conversion of shares of Series B and Series C Convertible
Preferred Stock shall include only shares designated as Common Stock of the
Corporation on the date of filing of this instrument, or in case of any
reorganization or reclassification of the outstanding shares thereof, the stock,
securities or assets provided for in subparagraph (g)(viii).

                  (xvii)        Mandatory Conversion.

                        (xvii)(1)   In the event that any time during the
period ending October 31, 1999, the fair market price of the Corporation's
Common Stock as quoted on NASDAQ, attains a price of Three ($3.00) Dollars per
share and maintains such price for at least ninety (90) days, all outstanding
shares of Series C Convertible Preferred Stock shall be automatically converted
into shares of Common Stock of the Corporation on such ninetieth day.

                        (xvii)(2)   In the event that at any time during
the period ending October 31, 1999, the fair market price of the
Corporation's Common Stock as


                                       14
<PAGE>

quoted on NASDAQ, attains a price of Six ($6.00) Dollars per share and maintains
such price for at least ninety (90) days, all outstanding shares of Series B
Convertible Preferred Stock shall be automatically converted into shares of
Common Stock of the Corporation on such ninetieth day.

                        (xvii)(3)   In the event that the holder of any
share or shares of Series C Convertible Preferred Stock shall not have converted
such share or shares prior to December 30, 2004, such share or shares shall be
automatically converted into shares of Common Stock of the Corporation.

                  (h)   Redemption.  The shares of Series B Convertible
Preferred Stock shall be redeemed as follows:

                        (h)(i)  Mandatory Redemption.  On December 30, 1999,
the Corporation shall redeem from each holder of shares of Series B Convertible
Preferred Stock, all of the shares of Series B Convertible Preferred Stock held
by such holder on said date.

                        (h)(ii) Redemption Price and Payment.  The Series B
Convertible Preferred Stock to be redeemed on the Redemption Date shall be
redeemed by paying for each share in cash an amount equal to $2.00 per share
plus, in the case of each share, an amount equal to all Accruing Dividends
unpaid thereon (whether or not declared) and any other dividends declared but
unpaid thereon, computed to the Redemption Date, such amount being referred to
as the "Redemption Price". Such payment shall be made in full on the Redemption
Date to the holders entitled thereto.

                        (h)(iii)    Redemption Mechanics.  At least 20 but
not more than 30 days prior to the Redemption Date, written notice (the
"Redemption Notice") shall be given by the Corporation by mail, postage prepaid,
or by telex to non-U.S. residents, to each holder of record (at the close of
business on the business day next preceding the day on which the Redemption
Notice is given) of shares of Series B Convertible Preferred Stock notifying
such holder of the redemption and specifying the Redemption Price, the
Redemption Date and the place where said Redemption Price shall be payable. The
Redemption Notice shall be addressed to each holder at his address as shown by
the records of the Corporation. From and after the close of business on the
Redemption Date, unless there shall have been a default in the payment of the
Redemption Price, all rights of holders of shares of Series B Convertible
Preferred Stock (except the right to receive the Redemption Price) shall cease
with respect to such shares, and such shares shall not thereafter be transferred
on the books of the Corporation or be deemed to be outstanding for any purpose
whatsoever. If the funds of the Corporation legally available for redemption of
shares of Series B Convertible Preferred Stock on the Redemption Date are
insufficient to redeem the total number outstanding shares of Series B
Convertible Preferred Stock, the holders of shares of Series B Convertible
Preferred Stock shall share ratably in any funds legally available for
redemption of such shares according to the respective amounts which would be
payable with respect to the full



                                       15
<PAGE>

number of shares owned by them if all such outstanding shares were redeemed in
full. The shares of Series B Convertible Preferred Stock not redeemed shall
remain outstanding and entitled to all rights and preferences provided herein.
At any time thereafter when additional funds of the Corporation are legally
available for the redemption of such shares of Series B Convertible Preferred
Stock, such funds will be used, at the end of the next succeeding fiscal
quarter, to redeem the balance of such shares, or such portion thereof for which
funds are then legally available, on the basis set forth above.

                        (h)(iv) Redeemed or Otherwise Acquired Shares to be
Retired. Any shares of Series B Convertible Preferred Stock redeemed pursuant to
this paragraph (h) or otherwise acquired by the Corporation in any manner
whatsoever shall be cancelled and shall not under any circumstances be reissued;
and the Corporation may from time to time take such appropriate corporation
action as may be necessary to reduce accordingly the number of authorized shares
of Series B Convertible Preferred Stock.

                  (i) Amendments. No provision of these terms of the Series B
and/or Series C Convertible Preferred Stock may be amended, modified or waived
without the written consent or affirmative vote of the holders of at least
two-thirds of the then outstanding shares of Series B and/or Series C
Convertible Preferred Stock."

      5. The foregoing amendment to the Certificate of Incorporation was
authorized by the Board of Directors at a meeting of the Board duly held on
September 29, 1994.

       ARTICLE XII - INDEMNIFICATION OF OFFICERS, DIRECTORS AND OTHERS

1.    GENERAL.

      The corporation shall, to the fullest extent permitted by the New York
Business Corporation Law as the same exists or, subject to Section 4 of this
Article, may hereafter be amended, indemnify any person who is or was made or
threatened to be made a party to or is involved in any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, against judgments, fines, amounts paid or to be paid in
settlement, excise taxes or penalties, and costs, charges and expenses,
including attorneys' fees incurred in connection with such action or proceeding
or any appeal therein. The actions for which such indemnification shall be
available shall include an action by or in the right of any other corporation of
any type or kind, domestic or foreign, or any partnership, joint venture, trust,
employee benefit plan or other enterprise, which any director or officer of the
corporation is


                                       11
<PAGE>

serving, has served or has agreed to serve in any capacity at the request of the
corporation, by reason of the fact that he or she, his or her testator,
testatrix or intestate, is or was or has agreed to become a director or officer
of the corporation, or is or was serving or has agreed to serve such other
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise in any capacity. Notwithstanding the foregoing, no indemnification
shall be provided to any such person if a judgment or other final adjudication
adverse to the director or officer establishes that (i) his or her acts were
committed in bad faith or were the result of active and deliberate dishonesty
and, in either case, were material to the cause of action so adjudicated, or
(ii) he or she personally gained in fact a financial profit or other advantage
to which he or she was not legally entitled. Except as provided in Section 6 of
this Article or as otherwise provided by agreement, the corporation shall
indemnify and such person seeking indemnification in connection with a
proceeding, or part thereof, initiated by such person only if such proceeding,
or part thereof, was authorized by the Board. The corporation may, to the extent
authorized from time to time by its Board, provide indemnification to employees
or agents of the Corporation who are not officers or directors of the
corporation with such scope and effect as determined by the Board.

2.    NON-EXCLUSIVITY OF RIGHTS.

      The corporation may indemnify any person to whom the corporation is
permitted to provide indemnification or the advancement of expenses by
applicable law, whether pursuant to rights granted pursuant to, or provided by,
the New York Business Corporation Law or other rights created by (i) a
resolution of shareholder, (ii) resolution of directors or (iii) an agreement
providing for such indemnification, it being expressly intended that these
by-laws authorize the creation of other rights in any such manner. The right to
be indemnified and to the reimbursement or advancement of expenses incurred in
defending a proceeding in advance of its final disposition conferred in this
Section shall not be exclusive of any other right which any person may have or
hereafter acquire under any statute, provision of the by-laws, agreement, vote
of shareholders or disinterested directors or otherwise.

3.    EXPENSES.

      The corporation shall, from time to time, reimburse or advance to any
person referred to in Section 1 of this Article the funds necessary for payment
of expenses, including attorneys' fees, incurred in connection with any such
action or proceeding upon receipt of a written undertaking by or on behalf of
such person to repay such amount(s) if a judgment or other final adjudication
adverse to the director or officer establishes that (i) his or her acts were
committed in bad faith or were the result of active and deliberate dishonesty
and, in either case, were material to cause of action so adjudicated, or (ii) he
or she personally gained in fact a financial profit or other advantage to which
he or she was not legally entitled.

4.    INTERPRETATION OF RIGHTS TO INDEMNIFICATION.

      Any person entitled to be indemnified or to the reimbursement or
advancement of expenses as a matter of right pursuant to this Section may elect
to have the right to


                                       12
<PAGE>

indemnification, or advancement of expenses, interpreted on the basis of the
applicable law in effect at the time of the occurrence of the event or events
giving rise to the action or proceeding, to the extent permitted by law, or on
the basis of the applicable law in effect at the time indemnification is sought.

5.    OTHER RIGHTS.

      The right to be identified or to the reimbursement or advancement of
expenses pursuant to this Article is: (i) a contract right pursuant to which the
person entitled thereto may bring suit as if the provisions hereof were set
forth in a separate written contract between the corporation and the director or
officer, (ii) intended to be retroactive and shall be available with respect to
events occurring prior to the adoption hereof and (iii) shall continue to exist
after the rescission or restrictive modification hereof with respect to events
occurring prior thereto.

6.    RIGHT OF CLAIMANT TO BRING SUIT.

      If a request to be indemnified is made under this Article, the corporation
shall make a determination pursuant to Section 723(b) of the New York Business
Corporation Law within thirty (30) days after such request as to whether the
person so requesting indemnification is entitled to indemnification under this
Article and the New York Business Corporation Law. If a request to be
indemnified or for the reimbursement or advancement of expenses under this
Article is not paid in full by the corporation within thirty (30) days after a
written claim has been received by the corporation, the claimant may at any time
thereafter bring suit against the corporation to recover the unpaid amount of
the claim and, if successful in whole or in part, the claimant shall be entitled
to be paid also the expense of prosecuting such claim. It shall be a defense to
any such action (other than an action brought to enforce a claim for expenses
incurred in defending any proceeding in advance of its final disposition where
the required undertaking, if any is required, has been tendered to the
corporation) that the claimant has not met the standards of conduct which make
it permissible under the New York Business Corporation Law or hereunder for the
corporation to indemnify the claimant for the amount claimed, but the burden of
proving such defense shall be on the corporation. Neither the failure of the
corporation to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in the
New York Business Corporation Law or hereunder, nor an actual determination by
the corporation that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

7.    INSURANCE.

      The corporation may maintain insurance, at its expense, to protect itself
and any director, officer, employee or agent of the corporation or another
corporation, partnership, joint venture, trust or other enterprise against any
such expense, liability or loss, whether or not the corporation would have the
power to indemnify such person against such expense, liability or loss under the
New York Business Corporation Law.

8.    SEPARABILITY.

      If this Article or any portion hereof shall be invalidated on any ground
by any court of competent jurisdiction, then the corporation shall nevertheless
indemnify each director, officer, employee or agent of the corporation as to
costs, charges and expenses, including attorneys' fee, judgments, fines and
amounts paid in settlement with respect to any action, suit or proceeding,
whether civil, criminal, administrative or investigative, including an action by
or in the right of the corporation, to the fullest extent permitted by any
applicable portion of this Article that shall not have been invalidated and to
the fullest extent permitted by applicable law.

                                                                   Exhibit 10.2

                           MEDICAL STERILIZATION, INC.

                                 1996 STOCK PLAN



         1. Purpose. The purpose of the Medical Sterilization, Inc. 1996 Stock
Plan (the "Plan") is to encourage key employees of Medical Sterilization, Inc.
(the "Company") and of any present or future parent or subsidiary of the Company
(collectively, "Related Corporations") and other individuals who render services
to the Company or a Related Corporation, by providing opportunities to
participate in the ownership of the Company and its future growth through (a)
the grant of options which qualify as "incentive stock options" ("ISOs") under
Section 422(b) of the Internal Revenue Code of 1986, as amended (the "Code");
(b) the grant of options which do not qualify as ISOs ("Non-Qualified Options");
(c) awards of stock in the Company ("Awards"); and (d) opportunities to make
direct purchases of stock in the Company ("Purchases"). Both ISOs and
Non-Qualified Options are referred to hereafter individually as an "Option" and
collectively as "Options." Options, Awards and authorizations to make Purchases
are referred to hereafter collectively as "Stock Rights." As used herein, the
terms "parent" and "subsidiary" mean "parent corporation" and "subsidiary
corporation," respectively, as those terms are defined in Section 424 of the
Code.

         2.       Administration of the Plan.

                  A. Board or Committee Administration. The Plan shall be
administered by the Board of Directors of the Company (the "Board") or by a
committee appointed by the Board (the "Committee"); provided that the Plan shall
be administered: (i) to the extent required by applicable regulations under
Section 162(m) of the Code, by two or more "outside directors" (as defined in
applicable regulations thereunder) and (ii) to the extent required by Rule 16b-3
promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), or any successor provision ("Rule 16b-3"), by a disinterested
administrator or administrators within the meaning of Rule 16b-3. Hereinafter,
all references in this Plan to the "Committee" shall mean the Board if no
Committee has been appointed. Subject to ratification of the grant or
authorization of each Stock Right by the Board (if so required by applicable
state law), and subject to the terms of the Plan, the Committee shall have the
authority to (i) determine to whom (from among the class of employees eligible
under paragraph 3 to receive ISOs) ISOs shall be granted, and to whom (from
among the class of individuals and entities eligible under paragraph 3 to
receive Non-Qualified Options and Awards and to make Purchases) Non-Qualified
Options, Awards and authorizations to make Purchases may be granted; (ii)
determine the time or times at which Options or Awards shall be granted or
Purchases made; (iii) determine the purchase price of shares subject to each
Option or Purchase, which prices shall not be less than the minimum price
specified in paragraph 6; (iv) determine whether each Option granted shall be an
ISO or a Non-Qualified Option; (v) determine (subject to paragraphs 7 and 8) the
time or times when each Option shall become exercisable and the duration of the
exercise period; (vi) extend the period during which outstanding Options may be
exercised; (vii) determine 

<PAGE>

whether  restrictions such as repurchase options and rights of first refusal are
to be imposed on shares subject to Options,  Awards and Purchases and the nature
of such  restrictions,  if any, and (viii)  interpret the Plan and prescribe and
rescind rules and  regulations  relating to it. If the  Committee  determines to
issue a Non-Qualified Option, it shall take whatever actions it deems necessary,
under Section 422 of the Code and the  regulations  promulgated  thereunder,  to
ensure  that such  Option  is not  treated  as an ISO.  The  interpretation  and
construction  by the  Committee  of any  provisions  of the Plan or of any Stock
Right granted under it shall be final unless otherwise  determined by the Board.
The  Committee  may from  time to time  adopt  such  rules and  regulations  for
carrying  out the Plan as it may deem  advisable.  No member of the Board or the
Committee  shall be liable  for any action or  determination  made in good faith
with respect to the Plan or any Stock Right granted under it.

                  B. Committee Actions. The Committee may select one of its
members as its chairman, and shall hold meetings at such time and places as it
may determine. A majority of the Committee shall constitute a quorum and acts of
a majority of the members of the Committee at a meeting at which a quorum is
present, or acts reduced to or approved in writing by all the members of the
Committee (if consistent with applicable state law), shall be the valid acts of
the Committee. From time to time the Board may increase the size of the
Committee and appoint additional members thereof, remove members (with or
without cause) and appoint new members in substitution therefor, fill vacancies
however caused, or remove all members of the Committee and thereafter directly
administer the Plan.

                  C. Grant of Stock Rights to Board Members. Subject to the
provisions of the first sentence of paragraph 2(A) above, if applicable, Stock
Rights may be granted to members of the Board. All grants of Stock Rights to
members of the Board shall in all other respects be made in accordance with the
provisions of this Plan applicable to other eligible persons. Consistent with
the provisions of the first sentence of Paragraph 2(A) above, members of the
Board who either (i) are eligible to receive grants of Stock Rights pursuant to
the Plan or (ii) have been granted Stock Rights may vote on any matters
affecting the administration of the Plan or the grant of any Stock Rights
pursuant to the Plan, except that no such member shall act upon the granting to
himself or herself of Stock Rights, but any such member may be counted in
determining the existence of a quorum at any meeting of the Board during which
action is taken with respect to the granting to such member of Stock Rights.

         3. Eligible Employees and Others. ISOs may be granted only to employees
of the Company or any Related Corporation. Non-Qualified Options, Awards and
authorizations to make Purchases may be granted to any employee, officer or
director (whether or not also an employee) or consultant of the Company or any
Related Corporation. The Committee may take into consideration a recipient's
individual circumstances in determining whether to grant a Stock Right. The
granting of any Stock Right to any individual or entity shall neither entitle
that individual or entity to, nor disqualify such individual or entity from,
participation in any other grant of Stock Rights.

         4. Stock. The stock subject to Stock Rights shall be authorized but
unissued shares of Common Stock of the Company, $. 01 par value (the "Common
Stock"), or shares of  

                                       2
<PAGE>
Common Stock reacquired by the Company in any manner. The aggregate number of
shares which may be issued pursuant to the Plan is 500,000, subject to
adjustment as provided in paragraph 13. If any Stock Right granted under the
Plan shall expire or terminate for any reason without having been exercised in
full or shall cease for any reason to be exercisable in whole or in part or
shall be repurchased by the Company, the shares of Common Stock subject to such
Stock Right shall again be available for grants of Stock Rights under the Plan.

         No employee of the Company or any Related Corporation may be granted
Options to acquire, in the aggregate, more than 300,000 shares of Common Stock
under the Plan. If any Option granted under the Plan shall expire or terminate
for any reason without having been exercised in full or shall cease for any
reason to be exercisable in whole or in part or shall be repurchased by the
Company, the shares subject to such Option shall be included in the
determination of the aggregate number of shares of Common Stock deemed to have
been granted to such employee under the Plan.

         5. Granting of Stock Rights. Stock Rights may be granted under the Plan
at any time on or after March 21, 1996 and prior to March 21, 2006. The date of
grant of a Stock Right under the Plan will be the date specified by the
Committee at the time it grants the Stock Right; provided, however, that such
date shall not be prior to the date on which the Committee acts to approve the
grant. Options granted under the Plan are intended to qualify as
performance-based compensation to the extent required under Treasury Regulation
Section 1.162-27.

         6.       Minimum Option Price; ISO Limitations.

                  A. Price for Non-Qualified Options, Awards and Purchases. The
exercise price per share specified in the agreement relating to each
Non-Qualified Option granted, and the purchase price per share of stock granted
in any Award or authorized as a Purchase, under the Plan shall in no event be
less than the minimum legal consideration required therefor under the laws of
any jurisdiction in which the Company or its successors in interest may be
organized. The Committee may, in its discretion, subject any Non-Qualified
Option granted under the Plan or Award made or Purchase authorized under the
Plan to any terms or conditions necessary for such Stock Right to qualify as
performance-based compensation under Section 162(m) of the Code and any
applicable regulations thereunder.

                  B. Price for ISOs. The exercise price per share specified in
the agreement relating to each ISO granted under the Plan shall not be less than
the fair market value per share of Common Stock on the date of such grant. In
the case of an ISO to be granted to an employee owning stock possessing more
than ten percent (10%) of the total combined voting power of all classes of
stock of the Company or any Related Corporation, the price per share specified
in the agreement relating to such ISO shall not be less than one hundred ten
percent (110%) of the fair market value per share of Common Stock on the date of
grant. For purposes of determining stock ownership under this paragraph, the
rules of Section 424(d) of the Code shall apply.

                  C. $100,000 Annual Limitation on ISO Vesting. Each eligible
employee may be granted Options treated as ISOs only to the extent that, in the
aggregate under this Plan and all incentive stock option plans of the Company
and any Related Corporation, ISOs do not



                                       3
<PAGE>
become exercisable for the first time by such employee during any calendar year
with respect to stock having a fair market value (determined at the time the
ISOs were granted) in excess of $100,000. The Company intends to designate any
Options granted in excess of such limitation as Non-Qualified Options.

                  D. Determination of Fair Market Value. If, at the time an
Option is granted under the Plan, the Company's Common Stock is publicly traded,
"fair market value" shall be determined as of the date of grant or, if the
prices or quotes discussed in this sentence are unavailable for such date, the
last business day for which such prices or quotes are available prior to the
date of grant and shall mean (i) the average (on that date) of the high and low
prices of the Common Stock on the principal national securities exchange on
which the Common Stock is traded, if the Common Stock is then traded on a
national securities exchange; or (ii) the last reported sale price (on that
date) of the Common Stock on the Nasdaq National Market, if the Common Stock is
not then traded on a national securities exchange; or (iii) the closing bid
price (or average of bid prices) last quoted (on that date) by an established
quotation service for over-the-counter securities, if the Common Stock is not
reported on the Nasdaq National Market. If the Common Stock is not publicly
traded at the time an Option is granted under the Plan, "fair market value"
shall mean the fair value of the Common Stock as determined by the Committee
after taking into consideration all factors which it deems appropriate,
including, without limitation, recent sale and offer prices of the Common Stock
in private transactions negotiated at arm's length.

         7. Option Duration. Subject to earlier termination as provided in
paragraphs 9 and 10 or in the agreement relating to such Option, each Option
shall expire on the date specified by the Committee, but not more than (i) ten
years from the date of grant in the case of Options generally and (ii) five
years from the date of grant in the case of ISOs granted to an employee owning
stock possessing more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or any Related Corporation, as determined
under paragraph 6(B). Subject to earlier termination as provided in paragraphs 9
and 10, the term of each ISO shall be the term set forth in the original
instrument granting such ISO, except with respect to any part of such ISO that
is converted into a Non-Qualified Option pursuant to paragraph 16.

         8. Exercise of Option. Subject to the provisions of paragraphs 9
through 12, each Option granted under the Plan shall be exercisable as follows:

            A. Vesting. The Option shall either be fully exercisable on the date
of grant or shall become exercisable thereafter in such installments as the
Committee may specify.

            B. Full Vesting of Installments. Once an installment becomes
exercisable it shall remain exercisable until expiration or termination of the
Option, unless otherwise specified by the Committee.

            C. Partial Exercise. Each Option or installment may be exercised at
any time or from time to time, in whole or in part, for up to the total number
of shares with respect to which it is then exercisable.



                                       4
<PAGE>

            D. Acceleration of Vesting. The Committee shall have the right to
accelerate the date that any installment of any Option becomes exercisable;
provided that the Committee shall not, without the consent of an optionee,
accelerate the permitted exercise date of any installment of any Option granted
to any employee as an ISO (and not previously converted into a Non-Qualified
Option pursuant to paragraph 16) if such acceleration would violate the annual
vesting limitation contained in Section 422(d) of the Code, as described in
paragraph 6(C).

         9. Termination of Employment. Unless otherwise specified in the
agreement relating to such ISO, if an ISO optionee ceases to be employed by the
Company and all Related Corporations other than by reason of death or disability
as defined in paragraph 10, no further installments of his or her ISOs shall
become exercisable, and his or her ISOs shall terminate on the earlier of (a)
ninety (90) days after the date of termination of his or her employment, or (b)
their specified expiration dates, except to the extent that such ISOs (or
unexercised installments thereof) have been converted into Non-Qualified Options
pursuant to paragraph 16. For purposes of this paragraph 9, employment shall be
considered as continuing uninterrupted during any bona fide leave of absence
(such as those attributable to illness, military obligations or governmental
service) provided that the period of such leave does not exceed 90 days or, if
longer, any period during which such optionee's right to reemployment is
guaranteed by statute. A bona fide leave of absence with the written approval of
the Committee shall not be considered an interruption of employment under this
paragraph 9, provided that such written approval contractually obligates the
Company or any Related Corporation to continue the employment of the optionee
after the approved period of absence. ISOs granted under the Plan shall not be
affected by any change of employment within or among the Company and Related
Corporations, so long as the optionee continues to be an employee of the Company
or any Related Corporation. Nothing in the Plan shall be deemed to give any
grantee of any Stock Right the right to be retained in employment or other
service by the Company or any Related Corporation for any period of time.

         10.      Death; Disability.

          A. Death. If an ISO optionee ceases to be employed by the Company and
all Related Corporations by reason of his or her death, any ISO owned by such
optionee may be exercised, to the extent otherwise exercisable on the date of
death, by the estate, personal representative or beneficiary who has acquired
the ISO by will or by the laws of descent and distribution, until the earlier of
(i) the specified expiration date of the ISO or (ii) 180 days from the date of
the optionee's death.

          B. Disability. If an ISO optionee ceases to be employed by the Company
and all Related Corporations by reason of his or her disability, such optionee
shall have the right to exercise any ISO held by him or her on the date of
termination of employment, for the number of shares for which he or she could
have exercised it on that date, until the earlier of (i) the specified
expiration date of the ISO or (ii) 180 days from the date of the termination of
the optionee's employment. For the purposes of the Plan, the term "disability"
shall mean 



                                       5
<PAGE>

"permanent and total disability" as defined in Section 22(e)(3) of
the Code or any successor statute.

         11. Assignability. No Stock Right shall be assignable or transferable
by the grantee except by will, by the laws of descent and distribution or, in
the case of Non-Qualified Options only, pursuant to a valid domestic relations
order. Except as set forth in the previous sentence, during the lifetime of a
grantee each Stock Right shall be exercisable only by such grantee.

         12. Terms and Conditions of Options. Options shall be evidenced by
instruments (which need not be identical) in such forms as the Committee may
from time to time approve. Such instruments shall conform to the terms and
conditions set forth in paragraphs 6 through 11 hereof and may contain such
other provisions as the Committee deems advisable which are not inconsistent
with the Plan, including restrictions applicable to shares of Common Stock
issuable upon exercise of Options. The Committee may specify that any
Non-Qualified Option shall be subject to the restrictions set forth herein with
respect to ISOs, or to such other termination and cancellation provisions as the
Committee may determine. The Committee may from time to time confer authority
and responsibility on one or more of its own members and/or one or more officers
of the Company to execute and deliver such instruments. The proper officers of
the Company are authorized and directed to take any and all action necessary or
advisable from time to time to carry out the terms of such instruments.

         13. Adjustments. Upon the occurrence of any of the following events, an
optionee's rights with respect to Options granted to such optionee hereunder
shall be adjusted as hereinafter provided, unless otherwise specifically
provided in the written agreement between the optionee and the Company relating
to such Option:

                  A. Stock Dividends and Stock Splits. If the shares of Common
Stock shall be subdivided or combined into a greater or smaller number of shares
or if the Company shall issue any shares of Common Stock as a stock dividend on
its outstanding Common Stock, the number of shares of Common Stock deliverable
upon the exercise of Options shall be appropriately increased or decreased
proportionately, and appropriate adjustments shall be made in the purchase price
per share to reflect such subdivision, combination or stock dividend.

                  B. Consolidations or Mergers. If the Company is to be
consolidated with or acquired by another entity in a merger, sale of all or
substantially all of the Company's assets or otherwise (an "Acquisition"), the
Committee or the board of directors of any entity assuming the obligations of
the Company hereunder (the "Successor Board"), shall, as to outstanding Options,
either (i) make appropriate provision for the continuation of such Options by
substituting on an equitable basis for the shares then subject to such Options
either (a) the consideration payable with respect to the outstanding shares of
Common Stock in connection with the Acquisition, (b) shares of stock of the
surviving corporation or (c) such other securities as the Successor Board deems
appropriate, the fair market value of which shall not materially exceed the fair
market value of the shares of Common Stock subject to such Options immediately
preceding the Acquisition; or (ii) upon written notice to the optionees, provide
that all Options must be exercised, to the extent then exercisable, within a
specified number of days of the date of such 



                                       6
<PAGE>

notice, at the end of which period the Options shall terminate; or (iii)
terminate all Options in exchange for a cash payment equal to the excess of the
fair market value of the shares subject to such Options (to the extent then
exercisable) over the exercise price thereof.

                  C. Recapitalization or Reorganization. In the event of a
recapitalization or reorganization of the Company (other than a transaction
described in subparagraph B above) pursuant to which securities of the Company
or of another corporation are issued with respect to the outstanding shares of
Common Stock, an optionee upon exercising an Option shall be entitled to receive
for the purchase price paid upon such exercise the securities he or she would
have received if he or she had exercised such Option prior to such
recapitalization or reorganization.

                  D. Modification of ISOs. Notwithstanding the foregoing, any
adjustments made pursuant to subparagraphs A, B or C with respect to ISOs shall
be made only after the Committee, after consulting with counsel for the Company,
determines whether such adjustments would constitute a "modification" of such
ISOs (as that term is defined in Section 424 of the Code) or would cause any
adverse tax consequences for the holders of such ISOs. If the Committee
determines that such adjustments made with respect to ISOs would constitute a
modification of such ISOs or would cause adverse tax consequences to the
holders, it may in its discretion refrain from making such adjustments.

                  E. Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, each Option will terminate
immediately prior to the consummation of such proposed action or at such other
time and subject to such other conditions as shall be determined by the
Committee.

                  F. Issuances of Securities. Except as expressly provided
herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares subject to Options. No adjustments shall be made for dividends paid in
cash or in property other than securities of the Company.

                  G. Fractional Shares. No fractional shares shall be issued
under the Plan and the optionee shall receive from the Company cash in lieu of
such fractional shares.

                  H. Adjustments. Upon the happening of any of the events
described in subparagraphs A, B or C above, the class and aggregate number of
shares set forth in paragraph 4 hereof that are subject to Stock Rights which
previously have been or subsequently may be granted under the Plan shall also be
appropriately adjusted to reflect the events described in such subparagraphs.
The Committee or the Successor Board shall determine the specific adjustments to
be made under this paragraph 13 and, subject to paragraph 2, its determination
shall be conclusive.

         14. Means of Exercising Options. An Option (or any part or installment
thereof) shall be exercised by giving written notice to the Company at its
principal office address, or to such transfer agent as the Company shall
designate. Such notice shall identify the Option being exercised and specify the
number of shares as to which such Option is being exercised, 



                                       7
<PAGE>
accompanied by full payment of the purchase price therefor either (a) in United
States dollars in cash or by check, (b) at the discretion of the Committee,
through delivery of shares of Common Stock having a fair market value equal as
of the date of the exercise to the cash exercise price of the Option, (c) at the
discretion of the Committee, by delivery of the grantee's personal recourse note
bearing interest payable not less than annually at no less than 100% of the
lowest applicable Federal rate, as defined in Section 1274(d) of the Code, (d)
at the discretion of the Committee and consistent with applicable law, through
the delivery of an assignment to the Company of a sufficient amount of the
proceeds from the sale of the Common Stock acquired upon exercise of the Option
and an authorization to the broker or selling agent to pay that amount to the
Company, which sale shall be at the participant's direction at the time of
exercise, or (e) at the discretion of the Committee, by any combination of (a),
(b), (c) and (d) above. If the Committee exercises its discretion to permit
payment of the exercise price of an ISO by means of the methods set forth in
clauses (b), (c), (d) or (e) of the preceding sentence, such discretion shall be
exercised in writing at the time of the grant of the ISO in question. The holder
of an Option shall not have the rights of a shareholder with respect to the
shares covered by such Option until the date of issuance of a stock certificate
to such holder for such shares. Except as expressly provided above in paragraph
13 with respect to changes in capitalization and stock dividends, no adjustment
shall be made for dividends or similar rights for which the record date is
before the date such stock certificate is issued.

         15. Term and Amendment of Plan.  This Plan was adopted by the Board on
March 21, 1996 subject, with respect to the validation of ISOs granted under the
Plan, to approval of the Plan by the shareholders of the Company at the next
Shareholders Meeting or, in lieu thereof, by written consent. If the approval of
shareholders is not obtained prior to March 21,1997, any grants of ISOs under
the Plan made prior to that date will be rescinded. The Plan shall expire at the
end of the day on March 20, 2006 (except as to Options outstanding on that
date). Subject to the provisions of paragraph 5 above, Options may be granted
under the Plan prior to the date of shareholder approval of the Plan. The Board
may terminate or amend the Plan in any respect at any time, except that, without
the approval of the shareholders obtained within 12 months before or after the
Board adopts a resolution authorizing any of the following actions: (a) the
total number of shares that may be issued under the Plan may not be increased
(except by adjustment pursuant to paragraph 13); (b) the benefits accruing to
participants under the Plan may not be materially increased; (c) the
requirements as to eligibility for participation in the Plan may not be
materially modified; (d) the provisions of paragraph 3 regarding eligibility for
grants of ISOs may not be modified; (e) the provisions of paragraph 6(B)
regarding the exercise price at which shares may be offered pursuant to ISOs may
not be modified (except by adjustment pursuant to paragraph 13); (f) the
expiration date of the Plan may not be extended; and (g) the Board may not take
any action which would cause the Plan to fail to comply with Rule 16b-3. Except
as otherwise provided in this paragraph 15, in no event may action of the Board
or shareholders alter or impair the rights of a grantee, without such grantee's
consent, under any Option previously granted to such grantee.

         16. Conversion of ISOs into Non-Qualified Options. The Committee, at
the written request or with the written consent of any optionee, may in its
discretion take such actions as may be necessary to convert such optionee's ISOs
(or any installments or portions of



                                       8
<PAGE>

installments thereof) that have not been exercised on the date of conversion
into Non-Qualified Options at any time prior to the expiration of such ISOs,
regardless of whether the optionee is an employee of the Company or a Related
Corporation at the time of such conversion. Such actions may include, but shall
not be limited to, extending the exercise period or reducing the exercise price
of the appropriate installments of such ISOs. At the time of such conversion,
the Committee (with the consent of the optionee) may impose such conditions on
the exercise of the resulting Non-Qualified Options as the Committee in its
discretion may determine, provided that such conditions shall not be
inconsistent with this Plan. Nothing in the Plan shall be deemed to give any
optionee the right to have such optionee's ISOs converted into Non-Qualified
Options, and no such conversion shall occur until and unless the Committee takes
appropriate action.

                  17. Application Of Funds. The proceeds received by the Company
from the sale of shares pursuant to Options granted and Purchases authorized
under the Plan shall be used for general corporate purposes.

                  18. Notice to Company of Disqualifying Disposition. By
accepting an ISO granted under the Plan, each optionee agrees to notify the
Company in writing immediately after such optionee makes a Disqualifying
Disposition (as described in Sections 421, 422 and 424 of the Code and
regulations thereunder) of any stock acquired pursuant to the exercise of ISOs
granted under the Plan. A Disqualifying Disposition is generally any disposition
occurring on or before the later of (a) the date two years following the date
the ISO was granted or (b) the date one year following the date the ISO was
exercised.

                  19. Withholding of Additional Income Taxes. Upon the exercise
of a Non-Qualified Option, the grant of an Award, the making of a Purchase of
Common Stock for less than its fair market value, the making of a Disqualifying
Disposition (as defined in paragraph 18), the vesting or transfer of restricted
stock or securities acquired on the exercise of an Option hereunder, or the
making of a distribution or other payment with respect to such stock or
securities, the Company may withhold taxes in respect of amounts that constitute
compensation includable in gross income. The Committee in its discretion may
condition (i) the exercise of an Option, (ii) the grant of an Award, (iii) the
making of a Purchase of Common Stock for less than its fair market value, or
(iv) the vesting or transferability of restricted stock or securities acquired
by exercising an Option, on the grantee's making satisfactory arrangement for
such withholding. Such arrangement may include payment by the grantee in cash or
by check of the amount of the withholding taxes or, at the discretion of the
Committee, by the grantee's delivery of previously held shares of Common Stock
or the withholding from the shares of Common Stock otherwise deliverable upon
exercise of a Option shares having an aggregate fair market value equal to the
amount of such withholding taxes.

                  20. Governmental Regulation. The Company's obligation to sell
and deliver shares of the Common Stock under this Plan is subject to the
approval of any governmental authority required in connection with the
authorization, issuance or sale of such shares.

                  Government regulations may impose reporting or other
obligations on the Company with respect to the Plan. For example, the Company
may be required to send tax information



                                      9
<PAGE>

statements to employees and former employees that exercise ISOs under the Plan,
and the Company may be required to file tax information returns reporting the
income received by grantees of Options in connection with the Plan.

                  21. Governing Law. The validity and construction of the Plan
and the instruments evidencing Options shall be governed by the laws of the
State of New York, or the laws of any jurisdiction in which the Company or its
successors in interest may be organized.

               RIDER TO LEASE DATED ____________, 1995 BETWEEN
             MEDICAL STERILIZATION, INC. AND BARLICH REALTY, INC.


      1.    TENANT'S RESPONSIBILITIES:

            A. Nothing to the contrary herein prevailing, the Tenant shall be
responsible for the functional integrity of the bearing members. All matters of
maintenance and management shall be the sole and exclusive responsibility of
Tenant. Tenant hereby covenants that it will make all reasonably necessary
repairs in a timely and effective manner, and should a defect in maintenance or
management of the demised premises not be remedied in a timely and effective
manner, the Landlord is hereby authorized to, without notice to Tenant, enter
upon the demised premises and make, on behalf of Tenant, the necessary repairs.
Any cost attendant upon such repairs shall be deemed additional rent to be paid
on the first day of the month next succeeding completion of the repairs.
Landlord (and its representative) shall be entitled to unlimited access to the
premises for purpose of inspection of all repairs and maintenance by Tenant and
to determine the need for same.

            B.    Tenant's responsibility for maintenance and management
shall be for all matters including, but not be limited to:

                  a) heat

                  b) ventilation

                  c) air conditioning

                  d) plumbing

                  e) parking

                  f) landscaping

                  g) insurance

                  h) snow removal

<PAGE>
                                       -9-


                  j) parking lot and driveways

                  k) structural, including roof, repairs

                  1) all taxes applicable to the ownership and occupation of
                     the demised premises

      C. Tenant will maintain the sidewalks in front of the demised premises by
sweeping same and keeping the same clear of snow and provide whatever janitorial
services may be necessary to keep the exterior walks clean. Further, the Tenant
agrees that it is solely responsible for the removal of garbage and debris which
may accumulate and that all garbage shall be bound neatly and firmly in suitable
containers and thereafter shall be placed in a metal container of the type
supplied by carting companies for the purpose of accumulating garbage, (for
example, a "dumpster"). Further, it shall be Tenant's responsibility to pay for
and enforce prompt and regular removal of its garbage and debris and that the
area or areas surrounding the storage of garbage and debris subject to
collection shall be made clear of refuse upon the ground and shall be maintained
daily by the Tenant to insure against collection or accumulation thereof. In the
event of the failure of the Tenant to generally comply with this regulation or
any part thereof, in the sole discretion of the Landlord, the Landlord may
engage (at Tenant's expense) whatever services may be necessary to maintain the
premises in a suitable degree of cleanliness and freedom from debris.

      2. SECURITY: It is intended that security shall equal two months rent and
any increase in annual rent provided for herein shall require an increase in
security so that security shall at all times equal two months of rent. The
security shall be for the sole and exclusive use of the Landlord and no
accountability for principal or interest accumulated or earned thereon shall be
required of Landlord by Tenant.


<PAGE>
                                      -10-


      3.    NO SUBLEASE OR ASSIGNMENT ALLOWED: Tenant shall not be permitted
to sublease or assign any or all of the demised premises without the advance
written approval of Landlord, which approval Landlord shall not reasonably
withhold.

            Notwithstanding the above, Landlord's consent shall not be required
for Tenant's subleasing or assigning up to 50% of the improvements on the
demised premises, provided the proposed assignee(s)/sublessee(s) meets
Landlord's reasonable imposed standards of financial responsibility.
Notwithstanding any assignment or sublease Tenant hereunder shall remain
primarily liable to Landlord for all Tenant's obligations under this Lease,
including for the payment of rent.

      4. DELIVERY IN "AS IS" CONDITION: Landlord delivers to Tenant the demised
premises in "as is" condition and makes no warranties that any or all parts
thereof will be in good working order as of the day of the commencement of this
lease.

      5.    INSURANCE:

            A.    Tenant shall insure the demised premises and the
improvements thereon as follows:

                  a) against the risk of fire or other casualty in the amount
                     of $5,000,000;

                  b) against the risk of public liability in the amount of
                     $5,000,000 for any one claim and $10,000,000 for any
                     number of claims arising from a single event.

                  c) Landlord and its shareholders, officers and directors
                     and any mortgagee shall be named insureds in all
                     policies.

            B. Tenant shall provide at Tenant's sole cost and expense insurance
insuring Landlord against any loss of rental during the term of this lease by
reason of casualty loss.


<PAGE>
                                      -11-


            C. The policies shall name Landlord, any person, firms or
corporations designated by Landlord, and Tenant as insured, and shall contain
clauses that the insurer will not cancel or change the insurances without first
giving the Landlord ten (10) days prior written notice. The insurances shall be
with insurance companies approved by Landlord and a copy of the policies or
certificates of insurance shall be delivered to Landlord. Upon a failure, after
demand, of the Tenant to obtain the insurance policies described hereinabove,
the Landlord is hereby authorized to obtain same in the limits set forth
hereinabove on behalf of the Tenant and the premiums for such policies shall be
due and payable with the installment of rent next due.

      6. FIXTURES: For the purposes of paragraph FIFTH hereof "movable trade
fixtures" shall be defined as: trade or other fixtures or equipment of Tenant
detachable from the realty by removal of screws, bolts or nails or the severing
of any wires by which such fixtures have been affixed to the floors, walls or
ceiling. Tenant shall at its own cost and expense, however, repair all damage to
the demised premises caused by the installation or removal of its trade or other
fixtures in default of which such repairs may be made by the Landlord at
Tenant's expense.

      7. INCREASED LOAD CAPACITY: If any use granted by this lease to the Tenant
shall result in a floor load in excess of the load capacity presently in
existence, Tenant is hereby granted the authority to increase the load capacity
in any manner permitted by law and subject to the same conditions imposed upon
Tenant herein for renovation of the demised premises except that Tenant shall
not be required to restore the property to it's former load capacity.

      8.    OMITTED.

      9.    ASSIGNMENT TO PARENT CORPORATION PERMITTED:


<PAGE>
                                      -12-


            A.    Tenant shall have the right to assign this lease to a
corporation which owns 51% percent of the stock of Tenant or to corporation in
which Tenant owns 50% percent of the stock provided (a) no assignment shall be a
release of Tenant and Tenant shall remain liable and responsible in all cases,
(b) that the assignee delivers to Landlord a duly executed assumption agreement
assuming and agreeing to all the terms and obligations of the lease in form
satisfactory to Landlord, and (c) that Tenant is not then in default of its
lease agreement.

            B. A subsequent reduction in either (a) Assignee's stock ownership
of Tenant to less than 51% percent or (b) Tenant's stock ownership of Assignee
to less than 50% percent shall, at Landlord's sole option, be deemed a
reassignment to Tenant. In the event of reassignment Assignee shall nevertheless
remain liable and responsible to Landlord for all of Tenant's and Assignee's
obligations under this lease as if reassignment to Tenant had not occurred.

            C. Landlord may exercise its option under paragraph B above at
anytime; and no acceptance of rent or other action by Landlord shall constitute
a waiver of Landlord's rights to exercise its option, whether such acceptance of
rent or action occurs before or after Landlord acquires knowledge of its right
to exercise such option.

      10.   NO BROKER:  Tenant hereby states that Tenant has not dealt with
any broker in connection with this lease.

      11.   IMPOSITIONS:

            A. Tenant shall pay (except as hereinafter provided), before any
fine, penalty, interest or cost may be added thereto, or become due or be
imposed by operation of law for the nonpayment thereof, all taxes, assessments,
water and sewer rents, rates and charges, charges for public utilities, levies
and all other license and permit fees and other governmental charges, 


<PAGE>
                                      -13-


general and special, ordinary and extraordinary, unforeseen and foreseen, of any
kind and nature whatsoever, which at any time prior to or during the term of
this lease may be assessed, levied, confirmed, imposed upon, or become due and
payable out of or in respect of, or become a lien on, the leased premises or any
part thereof or any appurtenance thereto, the rent payable hereunder, any use or
occupation of the leased premises (all collectively hereinafter referred to as
"Impositions," and each of the above being hereinafter referred to as an
"Imposition").

            B. If by law any Imposition may at the option of the payor be paid
in installments (whether or not interest shall accrue on the unpaid balance of
such Imposition), Tenant may exercise the option to pay the same (and any
accrued interest on the unpaid balance of such Imposition) in installments and,
in such event, shall pay such installments as they become due and before any
fine, penalty, further interest or cost may be added thereto. Upon termination
of this lease, Tenant shall forthwith prepay any installments which fall due
after termination.

            C. Any Imposition (other than Impositions which have been converted
into installment payments by Tenant as referred to in subdivision B above)
relating to a fiscal period of the taxing authority, a part of which period is
included within the term of this lease and a part of which is included in a
period of time before or after the expiration of the term of this lease, shall
(whether or not such Imposition shall be assessed, levied, confirmed, imposed
upon or in respect of or become a lien upon the leased premises, or shall become
payable, during the term of this lease) be adjusted between Landlord and Tenant
as of the commencement or expiration of the term of this lease, so that Tenant
shall pay that portion of such Imposition which that part of such fiscal period
included in the period of time after the commencement and before the expiration
of the term of this lease bears to such fiscal period, and Landlord shall pay
the 



<PAGE>
                                      -14-


remainder thereof; the above provided, however, that the term of this lease
shall not have been shortened due to Tenant's default in the performance of any
of the Tenant's covenants, agreements and undertakings in this lease provided.
If Tenant is in default and as a result the term of this expires prior to its
expiration date absent such default, then there shall be no such apportionment,
in which case Tenant shall pay the Imposition for the entire remaining term of
this lease. However, if the premises be relet Tenant's obligations for
Impositions shall be apportioned only through the commencement date of the new
lease.

            D. Nothing to the contrary herein contained shall require Tenant to
pay any municipal, state or federal income taxes assessed against Landlord, or
any municipal, state or federal capital levy, estate, succession, inheritance or
transfer taxes of Landlord, or any corporation franchise taxes imposed upon any
corporate owner of the fee of the leased premises; provided, however, that if at
any time during the term of this lease the methods of taxation prevailing at the
commencement of the term hereof shall be altered so as to cause the whole or any
part of the taxes, assessments, levies, impositions or charges now or hereafter
levied, assessed or imposed on real estate and the improvements thereon, to be
levied, assessed or imposed, wholly or partially as a capital levy, or
otherwise, on the rents received therefrom, or if any tax, corporation franchise
tax, assessment, levy (including but not limited to any municipal, state or
federal levy), imposition or charge, or any part thereof, shall be measured by
or based in whole or in part, upon the value of the leased premises and shall be
imposed upon Landlord, then all such taxes, assessments, levies, impositions or
charges, or the part thereof so measured or based, shall be deemed to be
included within the term "Impositions" for the purposes hereof, to the extent
that such Impositions would be payable if the leased Premises were the only
property 



<PAGE>
                                      -15-


of Landlord subject to such Impositions, and Tenant shall pay and discharge the
same as herein provided in respect of the payment of Impositions.

            E. Landlord shall promptly forward to Tenant all tax bills received
relating to the leased premises. Tenant will furnish to Landlord, within ten
(10) days after the date when any Imposition would become delinquent, official
receipts of the appropriate taxing authority, or other evidence satisfactory to
Landlord, evidencing the payment thereof. However, failure to furnish same shall
not be deemed a default unless Tenant fails to comply with this requirement
within 15 days after written request by Landlord.

            F. Tenant shall have the right to contest the amount or validity, in
whole or in part, of any Imposition by appropriate proceedings diligently
conducted in good faith but only after payment of such Imposition, unless such
payment would operate as a bar to such contest or interfere materially with the
prosecution thereof, in which event Tenant may postpone or defer payment of such
Imposition if

                  (1) neither the leased premises nor any part thereof would by
reason of such postponement or deferment be in danger of being forfeited or
lost, and

                  (2) Tenant shall have deposited with Landlord the amount so
contested and unpaid, together with all interest and penalties in connection
therewith and all charges that might be assessed against or become a charge on
the leased premises or any part thereof in and/or during the course of such
proceedings, and

                  (3) Landlord shall not be in danger of being subjected to
criminal liability or penalty by reason of such postponement.

            G. Upon the termination of any such proceedings (which shall include
any appeals from and petitions for review of any orders, decrees or judgments
deemed by Tenant to 



<PAGE>
                                      -16-


be adverse or unfavorable, Tenant shall pay the amount of such Imposition or
part thereof as finally determined in such proceedings, the payment of which may
have been deferred during the prosecution of such proceedings, together with any
costs, fees, interest, penalties or other liabilities in connection therewith,
and, upon such payment, Landlord shall return, without interest, any amount
deposited with it with respect to such Imposition as aforesaid, or, at the
written request of Tenant, Landlord shall make available to Tenant, upon such
reasonable conditions as Landlord may prescribe, the amount of such deposit for
the making of such payment as aforesaid. If, at any time during the continuance
of such proceedings, Landlord shall reasonably deem the amount deposited as
aforesaid insufficient, Tenant shall, upon demand, make an additional deposit of
such sum as Landlord reasonably may request, and upon failure of Tenant so to
do, the amount previously deposited may be applied by Landlord (unless such
application would prejudice or otherwise adversely affect Tenant's rights in
such proceedings, including any rights to appeal or to seek petitions for the
review of any adverse order, decree or judgment issued in such proceedings) to
the payment, removal and discharge of such Imposition, and the interest and
penalties in connection therewith and any costs, fees or other liability
accruing in any such proceedings, and the balance, if any, shall be returned to
Tenant.

            H. Tenant, at Tenant's sole cost and expense, shall have a right to
seek a reduction in the valuation of the leased premises as assessed for tax
purposes and to prosecute any action or proceeding which may be appropriate for
seeking or obtaining such reduction. To the extent to which any tax refund
payable as a result of any proceeding which Tenant may institute, or payable by
reason of compromise or settlement of any such proceeding, may be based upon, a
payment made by Tenant and shall not relate to a period as to which
apportionment thereof has been made with Landlord, Tenant shall be authorized to
collect the 



<PAGE>
                                      -17-


same, subject to Tenant's obligation to reimburse Landlord forthwith for any
expenses and fees incurred by Landlord in connection therewith. Landlord may
(but shall not be obligated to) at its own expense, if it shall so desire,
endeavor at any time or times to obtain a reduction of the assessed valuation
upon the leased premises or any part thereof for the purpose of reducing taxes
thereon, and, in such event, Tenant will cooperate in effecting such a 
reduction.

            I. Landlord shall not be required to join in any proceedings
referred to in paragraphs F or H hereof unless the provisions of any law, rule
or regulation at the time in effect shall require that such proceedings be
brought by and/or in the name of Landlord or any owner of the leased premises,
in which event Landlord shall join in such proceedings or permit the same to be
brought in its name, in which event Tenant shall reimburse Landlord for its
costs (including attorney's fees) incurred in connection with any such
proceeding. Landlord shall not ultimately be subjected to any liability for the
payment of any costs or expenses in connection with any such proceedings, and
Tenant will indemnify and save harmless Landlord from any such costs and
expenses. Except as otherwise provided in this lease, Tenant shall be entitled
to any refund of any Imposition and penalties or interest thereon received by
Landlord which have been paid by Tenant, or which have been paid by Landlord but
previously reimbursed in full by Tenant.

            J. The certificate, advice, or bill of the appropriate official
designated by law to make or issue the same or to receive payment of any
Imposition, certifying nonpayment of such Imposition, shall be prima facie
evidence that such Imposition is due and unpaid at the time of the making or
issuance of such certificate, advice or bill.

            K. Landlord appoints Tenant the attorney-in-fact of Landlord for the
purpose of making all payments to be made by Tenant pursuant to any of the
provisions of this lease to 



<PAGE>
                                      -18-


persons or entities other than Landlord. In case any person or entity to whom
any sum is directly payable by Tenant under any of the provisions of this lease
shall refuse to accept payment of such sum from Tenant, Tenant shall thereupon
give written notice of such fact to Landlord and shall pay such sum directly to
Landlord who shall thereupon pay such sum to such person or entity.

      12. ADDITIONAL RENT: In addition to the base rent, the Tenant shall pay as
additional rent all other sums of money or charges required to be paid by Tenant
under this Lease whether or not the same be designated "additional rent." If
such amounts or charges are not paid at the time provided in this Lease, they
shall nevertheless, if not paid when due, be collectible as additional rent with
the next installment of rent thereafter falling due hereunder, but nothing
herein contained shall be deemed to suspend or delay the payment of any amount
or money or charge at the time the same becomes due and payable hereunder, or
limit any other remedy of the Landlord.

      13. INDEMNIFICATION AND WAIVER OF SUBROGATION: Tenant will indemnify
Landlord and save it harmless from and against any and all claims, actions,
damages, liability and expense in connection with loss of life, personal injury
and/or damage to property arising from or out of any occurrence in, upon or at
the leased premises or any part thereof. In case Landlord shall, without fault
on its part, be made a party to any litigation commenced by or against Tenant,
then Tenant shall protect and hold Landlord harmless and shall pay all costs,
expenses and reasonable attorneys' fees incurred or paid by Landlord in
connection with such litigation.


<PAGE>
                                      -19-


            Tenant hereby waives any and all claims of damage or loss against
the Landlord. Tenant shall obtain in all insurance policies insuring the Tenant
for any loss, injury or damages whatsoever, a waiver of subrogation against the
Landlord, its agents and employees.

      14. LEGAL EXPENSES: In the event that the Landlord shall have to bring any
action or proceeding against Tenant for the recovery of money damages or for
possession of the Premises by reason of nonpayment of rent, additional rent or
other sum by Tenant, or by reason of non-performance by Tenant of the terms and
conditions of the Lease herein or by reason of a breach of the Lease herein by
Tenant, and the Landlord shall incur costs and expenses by reason thereof, such
reasonable charges, including legal fees, shall be due and payable from the
Tenant as additional rent, and shall become immediately due and payable upon the
incurment of same.

      15. NONLIABILITY OF LANDLORD: Landlord or its agents shall not in any
event whatsoever be liable for any injury or damage to any person or property
happening on or about the demised premises, or for any injury or damage to the
demised premises, or to any property of Tenant or to any property of any other
person, firm, association, or corporation on or about the demised premises from
whatever cause whatsoever including, but not limited to, fire, theft, explosion,
falling plaster, steam, gas, electricity, water, rain or snow or leaks from any
part of said building or from the pipes, appliances or plumbing works or from
the roof. Tenant shall give immediate notice to Landlord in case of fire or
accidents in the demised premises or of defects therein or in any fixtures or
equipment. If the Tenant shall fail to keep in force and effect the insurance
hereinabove set forth, then the Tenant shall indemnify and save harmless the
Landlord from and against any and all suits, claims, demands of every kind and
nature, including reasonable counsel fees by or on behalf of any person, firm,
association or corporation arising out of or based upon any accident, injury or
damage, however occurring, which shall or may happen on 



<PAGE>
                                      -20-


or about the demised premises, or in or about the vaults, streets, sidewalks or
curbs in front of or adjacent thereto, and from and against any matter or thing
growing out of the condition, maintenance, repair, alteration, use, occupation,
or operation of the demised premises or of the vaults, streets, sidewalks or
curbs in front of or adjacent thereto.

      16. REPOSSESSION: On the last day of the term hereof or on the earlier
termination thereof, Tenant shall peaceably and quietly leave, surrender and
deliver up to Landlord the demised premises broom-clean, together with the
building or any new building and all alterations, changes, additions and
improvements which may have been made upon the premises (except movable
furniture or movable trade fixtures put in at the expense of Tenant) in good
repair and good order and safe condition except for reasonable wear and tear.
Tenant, on or before said date shall remove all of Tenant's personal property
from the demised premises and all property not so removed shall be deemed to
have been abandoned and may be appropriated, sold, stored, destroyed or
otherwise disposed of by Landlord without notice to Tenant and without
obligation to account therefor, but at Tenant's cost. Tenant's obligations under
this paragraph shall be deemed to survive the expiration or other termination of
this Lease.

      17. FIXTURES ATTACHED TO REALTY: Any and all improvements in the property
and any and all structures or fixtures, except movable trade fixtures, not
attached to the realty shall be deemed attached to the freehold and
automatically become the property of Landlord upon installation unless Landlord
shall elect otherwise, which election shall be made by giving a notice not more
than sixty (60) days after the expiration or other termination of this Lease.

      18. NO ABATEMENT OR RENT: No diminution or abatement of rent or other
compensation shall be claimed or allowed for inconvenience or discomfort arising
from the 



<PAGE>
                                      -21-


making of repairs or improvements to the building or to its appliances, nor for
any space taken to comply with any law, ordinance or order of a governmental
authority. The Landlord shall not be required to furnish, and the Tenant shall
not be entitled to receive any "services" from the Landlord. Neither shall there
be any abatement or diminution of rent because of making of repairs,
improvements, or decorations to the demised premises after the date above fixed
for the commencement of the term, it being understood and agreed that rent
shall, in any event, commence to run at such date so above fixed.

      19.   VALIDITY OF LEASE NOTWITHSTANDING UNENFORCEABILITY OF LEASE
PROVISION:  The invalidity or unenforceability of any portion of the within
Lease Agreement shall in no way affect the validity or enforceability of any
other provision hereof.

      20. NO ORAL AGREEMENTS: There are no oral agreements between the parties
hereto affecting this Lease and this Lease supersedes and cancels any and all
previous representations, negotiations, arrangements and understandings, if any,
between the parties hereto with respect to the subject matter hereof, and they
shall not be used to interpret or construe this Lease.

<PAGE>
                                      -22-


            Tenant will keep the demised premises heated during the heating
season of each year during the term hereof and will protect the pipes from
freezing. Throughout the term of this Lease, Tenant shall maintain at its sole
cost and expense and keep in full force and effect for the benefit of Landlord,
with a company doing business in Nassau County, deemed responsible by the
Landlord, a service, repair and maintenance contract with respect to the
heating, ventilating and air-conditioning systems of the Premises. A copy of
such contract shall be delivered to Landlord together with a copy of the paid
bill.

      22. RIDER SUPERSEDES PRINTED PORTION OF LEASE: If in this Lease there is
any conflict between the provisions of any of the printed portions of this Lease
and this Rider, the provisions of this Rider shall be deemed to supersede the
printed provisions.

      23. LOCAL LAW: Any reference in the printed portions of this Lease to the

      24. SUMS DUE LANDLORD: In any case in which the Rent, additional rent or
other sum due is not paid within 10 days of the day when same is due, Tenant

laws, regulations and statutes, and constitutes an agreement between Landlord
and Tenant as to the estimated compensation for costs and administrative
expenses incurred by Landlord due to the late payment of rent to Landlord by
Tenant. Tenant further agrees that the late charge assessed pursuant to this
Lease is not interest.

      25. UTILITY EASEMENTS: This Lease is subject and subordinate to any
utility, gas, water and electric, light or telephone line easements affecting
the demised premises (a) now 



<PAGE>
                                      -23-

utilities through Tenant's premises if required.

      26. SIGNS: Landlord consents to Tenant's present signage. In the future
Tenant shall erect only dignified signs from the exterior to the demised

prior written approval of Landlord as to size, content, place and manner of
erection, which consent shall not be unreasonably withheld.

      27. LIMIT OF LIABILITY: In the event any clause in this Lease is deemed
null and void, or in the event any clause in this Lease may impart a liability
or obligation on the part of Landlord, then it is understood between the parties
to this Lease Agreement that the dollar amount of Landlord's liability herein
shall be limited to the extent of Landlord's interest in the property being
rented herein reduced by the amount of any mortgage then an encumbrance on the
premises.

      28. EXCUSE OF LANDLORD'S PERFORMANCE: Anything in this agreement to the
contrary notwithstanding, providing such cause is not due to the willful act or
neglect of the Landlord, the Landlord shall not be deemed in default with
respect to the performances of any of the terms, covenants and conditions of
this Lease if same shall be due to any strike, lockout, civil commotion,
war-like operation, invasion, rebellion, hostilities, military or usurped power,
sabotage, governmental regulations or controls, inability to obtain any
material, service or financing through Act of God or other cause beyond the
control of the Landlord.

      29. PERMITS: Tenant at its own cost and expense shall procure all
necessary certificates, permits, orders or licenses which may be required for
the conduct of its business by 



<PAGE>
                                      -24-


any governmental statute, regulation, ordinance or agency and insure that all
requirements relating to the uses of the demised premises by the Tenant shall be
complied with by the Tenant at its own cost and expense.

      30. DEFINITION OF LANDLORD: As used in this Lease, the term "Landlord"
shall mean only the owner or the mortgagee in possession for the time being of
the building in which the demised premises are located so that in the event of
any sale of said building or an assignment of this lease or any underlying lease
or a demise of both said building and land, Landlord shall be and hereby is
entirely released and discharged from any and all further liability and
obligations of Landlord hereunder, except any that may have theretofore accrued.

            Notwithstanding anything to the contrary provided in this Lease, it
is specifically understood and agreed, such agreement being a primary
consideration of this Lease by Landlord, that there shall be absolutely no
personal liability on the part of Landlord, its successors, assigns or any
mortgagee in possession (for the purposes of this paragraph collectively
referred to as "Landlord"), with respect to any of the terms, covenants and
conditions of this Lease, and that Tenant shall look solely to the equity of
Landlord in the demised premises for the satisfaction of each and every remedy
of Tenant in the event of any breach by Landlord of any of the terms, covenants
and conditions of this Lease to be performed by Landlord, such exculpation or
liability to be absolute and without exceptions whatsoever.

            Any sale of the subject premises shall be subject to this Lease.

      31.   TENANT'S CERTIFICATE:  Tenant shall, without charge at any time
and from time to time, within ten (10) days after request by Landlord, certify
by written instrument, duly executed, acknowledge and delivered, to any
mortgagee, assignee of any mortgagee, purchaser, or any other person, firm or
corporation specified by Landlord:


<PAGE>
                                      -25-


            (a)   That this Lease is unmodified and in full force and effect
                  (or, if there has been modification, that the same is in full
                  force and effect as modified and stating the modifications);

            (b)   whether or not there are then existing any set-offs or
                  defenses against the enforcement of any of the agreements,
                  terms, covenants or conditions hereof upon the part of Tenant
                  to be performed or complied with (and, if so, specifying the
                  same); and

            (c)   the dates, if any, to which the rental and other charges
                  hereunder have been paid in advance and/or to which Landlord
                  may have consented, released or relieved Tenant from Tenant's
                  obligations fully to perform all of the terms, covenants and
                  conditions of the Lease on Tenant's part to be performed.

      32. HOLDING OVER: If the Tenant retains possession of the demised premises
or any part thereof after the termination of the term by lapse of time or
otherwise, without prior written approval of Landlord, the Tenant shall pay the
Landlord rent at double the monthly rental otherwise applicable as set forth on
the first page of this lease for the time the Tenant thus remains in possession,
and in addition thereto, shall pay the Landlord all damages, consequential as
well as direct, sustained by reason of the Tenant's retention of possession. If
the Tenant remains in possession of the demised premises, or any part thereof,
after the termination of the term by lapse of time or otherwise, such holding
over shall at the election of the Landlord expressed in a written notice to the
Tenant and not otherwise, constitute an extension of this Lease on a
month-to-month basis at double the monthly rental otherwise applicable as set
forth 


<PAGE>
                                      -26-


on the first page of this lease. The provisions of this section do not
exclude the Landlord's right of re-entry or any other right hereunder.

      33. MECHANICS' LIENS: If, because of any act or omission of Tenant or
anyone claiming through or under Tenant, any mechanics' or other lien or order
for the payment of money shall be filed against the demised premises or the
building, or against Landlord (whether or not such lien or order is valid or
enforceable as such), Tenant shall, at Tenant's own cost and expense, cause the
same to be canceled and discharged of record within thirty (30) days after the
date of entry or filing thereof, and shall also indemnify and save harmless
Landlord from and against any and all costs, expenses, claims, losses or
damages, including reasonable counsel fees, resulting therefrom or by reason
thereof.

      34.   RIGHTS RESERVED BY LANDLORD:

            A. Landlord reserves the right to enter the demised premises at all
reasonable times (1) for the making of inspections as Landlord may deem
necessary or desirable, (2) to exhibit the premises to prospective purchasers or
lessees of the building and/or land which same is situated, and (3) for any
purpose whatsoever relating thereto or to the safety, protection or preservation
of the demised premises or of the building or of Landlord's interest.

            B. If during the last six (6) months of the term or of a renewal
term, Tenant shall have removed all or substantially all of Tenant's property
therefrom, Landlord may immediately enter and alter, renovate, and redecorate
the premises without reduction or abatement of rent or incurring any liability
to Tenant for compensation.

            C. Landlord may exercise any or all of the foregoing rights hereby
reserved to Landlord without being deemed guilty of an eviction, actual or
constructive, or disturbance or interruption of Tenant's use or possession and
without being liable in any manner toward Tenant 


<PAGE>
                                      -27-


and without limitation or abatement of rent or other compensation, and such acts
shall have no effect on this Lease.

      35. SPRINKLERS: If there now is or shall be installed in the building a
"sprinkler system" and such system or any of its appliances shall be damaged,
injured or not in proper working order, Tenant shall forthwith restore the same
to good working condition at its own expense. If the Board of Fire Underwriters
or any bureau, department or official of the state or city government having
jurisdiction shall require or recommend that any changes, modifications,
alterations or additional sprinkler heads or other equipment be made or supplied
by reason of Tenant's business, or the location of partitions or trade fixtures
or other contents of the demised, premises, or for any other reason, then all
such changes, modifications, alterations, additional sprinkler heads or other
equipment as are required or recommended and/or are reasonably necessary to
prevent the imposition of a penalty or charge against the full allowance for a
sprinkler system in the fire insurance rate as fixed by said Board, or by any
Fire Insurance Company, shall be promptly made or installed at Tenant's expense.

      36. INTEREST: Any payment required to be made by Tenant pursuant to this
Lease including all payments of rent, additional rent or other charges, not made
by Tenant within 10 days of its due date shall thereupon be deemed to be due and
payable by Tenant to Landlord on demand with interest thereon from the date when
the particular amount becomes due to the date of payment thereof to Landlord at
the rate of ten (10%) percent per annum.

      37. VIOLATIONS OF COVENANTS: If (a) Tenant violates any of the covenants,
agreements and conditions of this lease or any of the rules and regulations now
or hereafter reasonably established by the Landlord and (b) Tenant fails within
10 days of the mailing of notice of such violation to the Tenant to either (1)
discontinue such violation or (2) if said 


<PAGE>
                                      -28-


violation is of a nature that cannot be completely cured or remedied within said
ten day period, and if Tenant shall not have diligently commenced during such
ten day period, and shall not thereafter with reasonable diligence and in good
faith proceed to remedy or cure such violation; then this lease shall
thenceforth, at the option of the Landlord, become null and void, and the
Landlord may re-enter without further notice or demand. The rent in such case
shall become due, be apportioned and paid on and up to the day of such reentry;
and the Tenant shall be liable for all loss or damage resulting from such
violation and breach of this Lease. No waiver by the Landlord of any violation
or breach of condition by the Tenant shall constitute or be construed as a
waiver of any other violation or breach of condition, nor shall lapse of time
after breach of condition by the Tenant before the Landlord shall exercise its
option under this paragraph operate to defeat the right of the Landlord to
declare this lease null and void and to re-enter upon the demised premises after
the said breach or violation.

      38. RECOVERY, IF ANY, UNDER LANDLORD'S INSURANCE: Landlord shall not be
required to maintain any insurance concerning the premises. However, (1) if for
its own reasons Landlord maintains insurance, (2) Tenant undertakes roof and/or
structural repairs covered by Landlord's insurance, and (3) if as a result of
the Landlord maintaining insurance monies are payable for roof and/or structural
repairs, then the amount of any such proceeds attributable to roof and/or
structural repairs shall be made available by the Landlord to the Tenant for
Tenant's use in effectuating such repairs.

Boston, Massachusetts, on January 30, 1989 at 10:00 a.m., or at such other
location date and time as may be agreed upon by the Purchasers and the Company
(such date and time being called the "Closing Date"). At the Closing the Company
shall issue and deliver to each Purchaser Notes, payable to the order of such
Purchase, in the principal amount set forth opposite the name of such Purchaser
under the heading "Principal Amount of Notes" on Schedule I and Warrants,
registered in the name of such Purchaser, to purchase (subject to adjustment as
provided therein) the number of shares of the Company's Common Stock set forth
opposite the name of such Purchaser under the heading "Warrant Shares" on
Schedule I. As payment in full for the Notes and Warrants being purchased by it
under this Agreement, and against delivery of the Notes and Warrants as
aforesaid, on the Closing Date each Purchaser shall deliver to the Company a
check payable to the Company, in the amount set forth opposite the name of such
Purchaser under the heading "Aggregate Purchase Price" on Schedule I, or shall
transfer such sum to the account of the Company by wire transfer.

         (b) Allocation of Purchase Price. The Company and the Purchasers,
having adverse interests and as a result of arm's length bargaining, agree that
(i) neither the Purchasers nor any of their respective partners have rendered or
have agreed to render any services to the Company in connection with this
Agreement or the issuance of the notes and Warrants; (ii) the Warrants are not
being issued as compensation; and (iii) for the purpose, and within the meaning,
of Proposed Treasury Regulation Section 1.1273-2(d)(2)(iv), the aggregate issue
price at which the Notes would be issued if they were issued apart from the
Warrants is $990,000.

         The Company and the Purchaser recognize that this Agreement determines
the original issue discount to be taken into account by the Company and the
Purchaser for Federal income tax purposes on the Notes, and they agree to adhere
to this Agreement for such purposes.

         SECTION 1.04 Payments and Endorsements. Payments of principal and
interest on the Notes shall be made directly by check duly mailed or delivered
to each Purchaser at its address set forth on Schedule I, without any
presentment or notation of payment, except that prior to any transfer of any
Note, the holder of record shall endorse on such Note a record of the date to
which interest has been paid and all payments made on account of principal of
such Note.

         SECTION 1.05 Demand for Payment. The principal of and interest on the
Notes shall be payable on demand made by a holder thereof. Any demand for
payment shall be made by written notice to the Company, which notice shall set
forth the date and time for such redemption, which shall not be less than five
(5) days after the date such notice was delivered to the Company. No demand for
payment may be made by any holder of the Notes prior to June 30, 1989 except in
the event that (i) at a duly held meeting of the stockholders of the Company
(the "Stockholders' Meeting") convened for the purposes of amending the
Company's Certificate of Incorporation, as amended through the date hereof (the
"Charter") as set forth in Exhibit C hereto, to provide for the creation of a

<PAGE>
                                       -8-


series of Preferred Stock (the "Preferred Stock") substantially on the terms set
forth in Exhibit D hereto (the "Charter Amendment"), such stockholders shall
fail to approve the Charter Amendment or (ii) Kenneth W. Rind, or such other
person as shall be nominated for election to the Board of Directors by the
holders of the Notes and the Warrants shall not have been so elected or shall
have been removed from the Board of Directors.

         SECTION 1.06 Payment on Non-Business Days. Whenever any payment to be
made shall be due on a Saturday, Sunday or a public holiday under the laws of
the State of New York, such payment may be made on the next succeeding business
day, and such extension of time shall in such case be included in the
computation of payment of interest due.

         SECTION 1.07 Registration, etc. The Company shall maintain at its
principal office a register of the Notes and shall record therein the names and
addresses of the registered holders of the Notes, the address to which notices
are to be sent and the address to which payments are to be made as designated by
the registered holder if other than the address of the holder, and the
particulars of all transfers, exchanges and replacements of Notes. No transfer
of a Note shall be valid unless made on such register for the registered holder
or his executors or administrators or his or their duly appointed attorney, upon
surrender therefor for exchange as hereinafter provided, accompanied by an
instrument in writing, in form and execution reasonably satisfactory to the
Company. Each Note issued hereunder, whether originally or upon transfer,
exchange or replacement of a Note or Notes, shall be registered on the date of
execution thereof by the Company or shall be dated the date to which interest
has been paid on such Notes or Note. The registered holder of a Note shall be
that Person in whose name the Note has been so registered by the Company. A
registered holder shall be deemed the owner of a Note for all purposes of this
Agreement and, subject to the provisions hereof, shall be entitled to the
principal and interest evidenced by such Note free from all equities or rights
of setoff or counterclaim between the Company and the transferor of such
registered holder or any previous registered holder of such Note.

         SECTION 1.08 Transfer and Exchange of Notes. The registered holder of
any Note or Notes may, prior to maturity thereof, surrender such Note or Notes
at the principal office of the Company for transfer or exchange. Within a
reasonable time after notice to the Company from a registered holder of its
intention to make such exchange and without expense (other than transfer taxes,
if any) to such registered holder, the Company shall issue in exchange therefor
another Note or Notes, in such denominations as requested by the registered
holder, for the same aggregate principal amount as the unpaid principal amount
of the Note or Notes so surrendered and having the same maturity and rate of
interest, containing the same provisions and subject to the same terms and
conditions as the Note or Notes so surrendered. Each new Note shall be made
payable to such Person or Persons, or registered assigns, as the registered
holder of such surrendered Note or Notes may designate, and such transfer or
exchange shall be made in such a manner that no gain or loss of principal or
interest shall result therefrom.

                                       -9-


         SECTION 1.09 Replacement of Notes. Upon receipt of evidence
satisfactory to the Company of the loss, theft, destruction or mutilation of any
Note and, if requested in the case of any such loss, theft or destruction, upon
delivery of an indemnity bond or other agreement or security reasonably
satisfactory to the Company, or, in the case of any such mutilation, upon
surrender and cancellation of such Note, the Company will issue a new Note, of
like tenor and amount and dated the date to which interest has been paid, in
lieu of such lost, stolen, destroyed or mutilated Note; provided, however, if
any Note of which any Purchaser, its nominee, or any of its partners is the
registered holder is lost, stolen or destroyed, the affidavit of an executive
officer or general partner of the registered holder setting forth the
circumstances with respect to such loss, theft or destruction shall be accepted
as satisfactory evidence thereof, and no indemnification bond or other security
shall be required as a condition to the execution and delivery by the Company of
a new Note in replacement of such lost, stolen or destroyed note other than the
registered holder's written agreement to indemnify the Company such certificates
evidencing shares of Preferred Stock.

         SECTION 1.10 Conversion of Notes.

         (a) Mandatory Conversion. All outstanding Notes shall automatically be
converted into the number of shares of Preferred Stock into which such Notes are
convertible upon application of the then effective Preferred Stock Conversion
Value immediately upon the filing by the Company of the Charter Amendment with
the Secretary of State of the State of New York and the creation of the
Preferred Stock. The date of such event shall referred to as the "Mandatory
Conversion Date".

         Upon the occurrence of an automatic conversion specified above, the
outstanding Notes shall cease to represent any obligation of the Company and
shall be converted automatically without any further action by the holders of
such Notes and whether or not the Notes are surrendered to the Company provided,
however, that the Company shall not be obligated to issue certificates
evidencing the shares of Preferred Stock issuable upon such conversion or to
make any interest payment unless the Notes being converted are either delivered
to the Company, or the holder notifies the Company that such Note has been lost,
stolen or destroyed and executes an agreement satisfactory to the Company to
indemnify the Company from any loss incurred by it in connection therewith;
provided, however, if any Note of which any Purchaser, its nominee, or any of
its partners is the registered holder is lost, stolen or destroyed, the
affidavit of an executive officer or general partner of the registered holder
setting forth the circumstances with respect to such loss, theft or destruction
shall be accepted as satisfactory evidence thereof, and no indemnification bond
or other security shall be required as a condition to the execution and delivery
by the Company of such certificates evidencing shares of Preferred Stock.

         Upon the occurrence of an automatic conversion specified above, the
holders of the Notes shall surrender the Notes at the office of the Company.
Thereupon, there shall be issued and delivered to such holder, a certificate or
certificates for the number of shares of Preferred Stock into which the Notes
surrendered were convertible on the date 



<PAGE>
                                      -10-


on which such automatic conversion occurred, cash in the amount of all accrued
and unpaid interest on such Note up to and including the Mandatory Conversion
Date, cash, as provided subsection 1.10(e), in respect of any fraction of a
share of Preferred Stock issuable upon such conversion and any other securities
or property to which the holder becomes entitled upon conversion pursuant to
this Section 1.10. Such conversion shall be deemed to have been effected
immediately after the filing of the Charter Amendment with the Secretary of
State of the State of New York and the creation of the Preferred Stock on the
Mandatory Conversion Date, and at such time the rights of the holder as holder
of a Note shall cease and the Person or Persons in whose name names any
certificate or certificates for shares of Preferred Stock shall be issuable upon
such conversion shall be deemed to have become the holder or holders of record
of the shares of Preferred Stock represented thereby.

         (b) Optional Conversion. In the event that the Charter Amendment has
not been filed with the Secretary of State of the State of New York and the
Preferred Stock has not been created on or prior to June 30, 1989, any holder of
the outstanding Notes after that date shall have the right, at its election, to
require the Company to convert any portion of the principal of and interest on
the Notes held by such holder into shares of Common Stock upon application of
the then effective Common Stock Conversion Value, by delivering written notice
to the Company, which notice shall set forth the date and time for such optional
conversion which shall be not less than five (5) days after the date such notice
was delivered to the Company (the "Optional Conversion Date"). Within five (5)
days of receipt of a notice of conversion, the Company shall send written notice
to all other holders of the Notes setting forth the identities of the converting
holders, the number of shares of Common Stock to be issued, and the Optional
Conversion Date.

         Upon the consummation of an optional conversion specified above, the
Notes so converted shall cease to represent any obligation of the Company and
shall be converted automatically without any further action by the holders of
such Notes and whether or not the Notes are surrendered to the Company;
provided, however, that the Company shall not be obligated to issue certificates
evidencing the shares of Common Stock issuable upon such conversion or to make
any interest payment unless the Notes being converted are either delivered to
the Company, or the holder notifies the Company that such Note has been lost,
stolen or destroyed and executes an agreement satisfactory to the Company to
indemnify the Company from any loss incurred by it in connection therewith;
provided, however, if any Note of which any Purchaser, its nominee, or any of
its partners is the registered holder is lost, stolen or destroyed, the
affidavit of an executive officer or general partner of the registered holder
setting forth the circumstances with respect to such loss, theft or destruction
shall be accepted as satisfactory evidence thereof, and no indemnification bond
or other security shall be required as a condition to the execution and delivery
by the Company of such certificates evidencing shares of Common Stock.

         Upon the consummation of an optional conversion specified above, the
holder of the Notes so converted shall surrender the Notes at the office of the
Company. 


<PAGE>
                                      -11-


Thereupon, there shall be issued and delivered to such holder, a certificate or
certificates for the number of shares of Common Stock into which the Notes
surrendered were convertible on the Optional Conversion Date, cash in the amount
of all accrued and unpaid interest on such Note up to and including the Optional
Conversion Date in the case that the holder of a Note does not elect to convert
such accrued and unpaid interest into shares of Common Stock, cash, as provided
in subsection 1.10(e), in respect of any fraction of a share of Common Stock
issuable upon such conversion and any other securities or property to which the
holder becomes entitled upon conversion pursuant to this Section 1.10. Such
conversion shall be deemed to have been effected immediately upon the Optional
Conversion Date, and at such time the rights of the holder as holder of a Note
shall cease and the Person or Persons in whose name or names any certificate or
certificates for shares of Common Stock shall be issuable upon such conversion
shall be deemed to have become the holder or holders of record of the shares of
Common Stock represented thereby.

         (c) Conversion Value. The price at which any Note may be converted into
Preferred Stock (the "Preferred Stock Conversion Value") pursuant to subsection
1.10(a) shall, subject to adjustment as hereinafter provided, be three dollars
and fifty cents ($3.50) in principal amount of the Note for each share of
Preferred Stock. The price at which any Note may be converted into Common Stock
(the "Common Stock Conversion Value") pursuant to subsection 1.10(b) shall,
subject to adjustment as hereinafter provided, be one dollar ($1.00) in
principal amount of the Note or in accrued and unpaid interest thereon for each
share of Common Stock.

         (d) No Dilution or Impairment. The Company will not, by amendment of
its Charter or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms of the
Notes, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the holders of shares of Preferred
Stock or Common Stock issuable upon conversion of the Notes against dilution or
other impairment. Without limiting the generality of the foregoing, the Company
(i) will not increase the par value of any shares of capital stock receivable on
the conversion of the Notes above the amount payable therefor on such
conversion, (ii) will take all action as may be necessary or appropriate in
order that the Company may validly and legally issue fully paid and
non-assessable shares of stock on the conversion of any Note from time to time
outstanding, and (iii) will not transfer all or substantially all of its
properties and assets to any other Person, or consolidate with or merge into any
other Person or permit any such Person to consolidate with or merge into the
Company (if the Company is not the surviving person), unless such other Person
shall expressly assume in writing and will be bound by all the terms of the
Notes.

         (e) Cash in Lieu of Fractional Shares. No fractional shares of
Preferred Stock or Common Stock or script representing fractional shares shall
be issued upon the conversion of a Note. Instead of any fractional shares of
Preferred Stock or Common 


<PAGE>
                                      -12-


Stock that would otherwise be issuable upon conversion of a Note, the Company
shall pay to the holder of the Note that was converted a cash adjustment in
respect of such fractional shares in an amount equal to the same fraction of the
market price per share of the Preferred Stock or Common Stock (as determined in
a reasonable manner prescribed by the Board of Directors) as the close of
business on the Mandatory Conversion Date or Optional Conversion Date, as the
case may be. The determination as to whether or not any fractional shares are
issuable shall be based upon the total Notes being converted at any one time by
and holder thereof, not upon each Note being converted.

         (f)      Notice of Record Date.  In the event of:

                  (i) any taking by the Company of a record of the holders of
any class of securities for the purpose of determining the holders thereof who
are entitled to receive any dividend or other distribution, or any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

                  (ii) any capital reorganization of the Company, and
reclassification or recapitalization of the capital stock of the Company, any
merger or consolidation of the company, or any transfer of all or substantially
all of the assets of the Company to any other corporation, or any other entity
or person, or

                  (iii) any voluntary or involuntary dissolution, liquidation or
winding up of the Company;

then and in each such event the Company shall mail or cause to be mailed to each
holder of a Note a notice specifying (i) the date on which any such record is to
be taken for the purpose of such dividend, distribution or right and a
description of such dividend, distribution or right, (ii) the date on which any
such reorganization, reclassification, recapitalization, transfer,
consolidation, merger, dissolution, liquidation or winding up is expected to
become effective and (iii) the time, if any, that is to be fixed, as to when the
holders of record of capital stock of the Company shall be entitled to exchange
their shares of capital stock of the Company for securities or other property
deliverable upon such reorganization, reclassification, recapitalization,
transfer, consolidation, merger, dissolution, liquidation or winding up. Such
notice shall be mailed at least seven (7) days prior to the date specified in
such notice on which such action is to be taken.

conducting its business in any jurisdiction in which it is now conducting
business or in which it proposes to conduct business.

         SECTION 2.08 Proprietary Information of Third Parties. To the best of
the Company's knowledge, no third party has claimed or has reason to claim that

violating any of the terms or conditions of his employment, non-competition or
non-disclosure agreement with such third party, (b) disclosed or may be
disclosing or utilized or may be utilizing any trade secret or proprietary
information or documentation of such third party or (c) interfered or may be
interfering in the employment relationship between such third party and any of
its present or former employees. No third party has requested information from
the Company which suggests that such a claim might be contemplated. To the best
of the Company's knowledge, no person employed by or affiliated with the Company
has employed or proposes to employ any trade secret or any information or
documentation proprietary to any former employer, and to the best of the
Company's knowledge, no person employed by or affiliated with the Company has
violated any confidential relationship which such person may have had with any
third party, in connection with the development, manufacture or sale of any
product or proposed product or the development or sale of any service or
proposed service of the Company, and the Company has no reason to believe there
will be any such employment or violation. To the best of the Company's
knowledge, none of the execution or delivery of this Agreement, or the carrying
on of the business of the Company as officers, employees or agents by any
officer, director or key employee of the Company, or the conduct or proposed
conduct of 


<PAGE>
                                      -18-


the business of the Company, will conflict with or result in a breach of the
terms, conditions or provisions of or constitute a default under any contract,
covenant or instrument under which any such person is obligated.

         SECTION 2.09 Title to Properties. The Company has good and marketable
title to its properties and assets reflected on the Balance Sheet or acquired by
it since the date of the Balance Sheet (other than properties and assets
disposed of in the ordinary course of business since the date of the Balance
Sheet), and all such properties and assets are free and clear of mortgages,
pledges, security interests, liens, charges, claims, restrictions and other
encumbrances, except for liens for or current taxes not yet due and payable and
minor imperfections of title, if any, not material in nature or amount and not
materially detracting from the value or impairing the use of the property
subject thereto or impairing the operations or proposed operations of the
Company.

         SECTION 2.10. Leasehold Interests. Each lease or agreement to which the
Company is a party under which it is a lessee of any property, real or personal,
is a valid and subsisting agreement without any default of the Company
thereunder and, to the best of the Company's knowledge, without any default
thereunder of any other party thereto. No event has occurred and is continuing
which, with due notice or lapse of time or both, would constitute a default or
event of default by the Company under any such lease or agreement or, to the
best of the Company's knowledge, by any other party thereto. The Company's
possession of such property has not been disturbed and, to the best of the
Company's knowledge, no claim has been asserted against the Company adverse to
its rights in such leasehold interests.

         SECTION 2.11. Insurance. The Company holds valid policies covering all
of the insurance required to be maintained by it under Section 5.05.

         SECTION 2.12 Taxes. The Company has filed all tax returns, Federal,
state, county and local, required to be filed by it, and the Company has paid
all taxes shown to be due by such returns as well as all other taxes,
assessments and governmental charges which have become due or payable, including
without limitation all taxes which the Company is obligated to withhold from
amounts owing to employees, creditors and third parties. All such taxes with
respect to which the Company has become obligated pursuant to elections made by
the Company in accordance with generally accepted practice have been paid and
adequate reserves have been established for all taxes accrued but not yet
payable. The Federal income tax returns of the Company have never been audited
by the Internal Revenue Service. No deficiency assessment with respect to or
proposed adjustment of the Company's Federal, state, county or local taxes is
pending or, to the best of the Company's knowledge, threatened. There is no tax
lien, whether imposed by any Federal, state, county or local taxing authority,
outstanding against the assets, properties or business of the Company. Neither
the Company nor any of its stockholders has ever filed (a) an election pursuant
to Section 1362 of the Internal Revenue Code of 1986, as amended (the "Code"),
that the Company be taxed as an S corporation or (b) consent pursuant to Section
341(f) of the Code, relating to collapsible


<PAGE>
                                      -19-


corporations. The Company's net operating losses for Federal income tax
purposes, as set forth in the financial statements referred to in Section 2.05,
are not subject to any limitations imposed by Section 382 of the Code and the
full amount of such net operating losses are available to offset the taxable
income of the Company for the current fiscal year and, to the extent not so
used, succeeding fiscal years. Consummation of the transactions contemplated by
this Agreement or by any other agreement, understanding or commitment
(contingent or otherwise) to which the Company is a party or by which it is
otherwise bound will not have the effect of limiting the Company's ability to
use such net operating losses in full to offset such taxable income.

         SECTION 2.13 Other Agreements. Except as set forth in the attached
Schedule V(A), the Company is not a party to or otherwise bound by any written
or oral contract or instrument or other restriction which individually or in the
aggregate could materially adversely affect the business, prospects, financial
condition, operations, property or affairs of the Company. Except as set forth

                  (e) contract for the future purchase of fixed assets or for

<PAGE>

                  (q) other contract, instrument, commitment, plan or

         a registration statement on From S-1 if the Company were registering
         securities under the Securities Act of 1933, as amended (the
         "Securities Act").

The Company, and to the best of the Company's knowledge, each other party
thereto have in all material respects performed all the obligations required to
be performed by them to date, have received no notice of default and are not in
default (with due notice or lapse of time or both) under any lease, agreement or
contract now in effect to which the Company is a party or by which it or its
property may be bound. The Company has no present expectation or intention of
not fully performing all its obligations under each such lease, contract or
other agreement, and the Company has no knowledge of any breach or anticipated
breach by the other party to any contract or commitment to which the Company is
a party. The Company is in full compliance with all of the terms and provisions
of its Charter and By-laws, as amended.

         SECTION 2.14 Patents, Trademarks, Etc. Set forth in Schedule II is a

right, and in each case a brief description of the nature of such right. The
Company owns or possesses adequate licenses or other rights to use all patents,
patent applications, trademarks, trademark applications, service marks, service
mark applications, trade names, copyrights, manufacturing processes, formulae,
trade secrets and know how (collectively, "Intellectual Property") necessary or

conducted, and no claim is pending or, to the best of the Company's knowledge,
threatened to the effect that the operations of the Company infringe upon or
conflict with the asserted rights of any other person under any Intellectual
Property, and there is no basis for any such claim (whether or not pending or
threatened). No claim is pending or threatened to the effect that any such
Intellectual Property owned or licensed by the Company, or which the Company
otherwise has the right to use, is invalid or unenforceable by the Company, and
there is no basis for any such claim (whether or not pending or threatened). To
the best of the Company's knowledge, all technical information developed by and
belonging to the Company which has not been patented has been kept confidential.
The Company has not granted or assigned to any other person or entity any right
to manufacture, have manufactured, assemble or sell the products or proposed

outstanding loans or advances to any person and is not obligated to make any

Persons. The Company has not assumed, guaranteed, endorsed or otherwise become
directly or contingently liable on any indebtedness of any other person

otherwise, to purchase, to provide funds for payment, to supply funds to or
otherwise invest in the debtor, or otherwise to assure the creditor against
loss), except for guaranties by endorsement of negotiable instruments for
deposit or collection in the ordinary course of business.

         SECTION 2.17 Significant Customers and Suppliers. No customer or
supplier which was significant to the Company during the period covered by the
financial statements referred to in Section 2.05 or which has been significant
to the Company thereafter, has terminated, materially reduced or threatened to
terminate or materially reduce its purchases from or provision of products or
services to the Company, as the case may be.

         SECTION 2.18 Governmental Approvals. Subject to the accuracy of the
representations and warranties of the Purchasers set forth in Article III, no
registration or filing with, or consent or approval of or other action by, any
Federal, state or other governmental agency or instrumentality is or will be

this Agreement, the Registration Rights Agreement or the Stock Restriction
Agreement, the issuance, sale and delivery of the Notes or the Warrants or, upon

have been made by the Company) in connection with the sale of the Notes and the
Warrants and (iii) with respect to the Registration Rights Agreement, the

         SECTION 2.19 Disclosure. Neither this Agreement, nor any Schedule or
Exhibit to this Agreement, nor the Business Plan of the Company for 1989 (the
"Business Plan"), contains an untrue statement of a material fact or omits a
material fact necessary to make the statements contained herein or therein not
misleading. None of the statements, documents, certificates or other items
prepared or supplied by the Company with respect to the transactions
contemplated hereby contains an untrue statement of a material fact or omits a
material fact necessary to make the statements contained therein not misleading.
There is no fact which the Company has not disclosed to the Purchasers and their
counsel in writing and of which the Company is aware which materially and
adversely affects or could materially and adversely affect the business,
prospects, financial condition, operations, property or affairs of the Company
or any of its subsidiaries. The financial projections and other estimates
contained in the Business Plan were prepared by the 


<PAGE>
                                      -23-


Company based on the Company's experience in the industry and on assumptions of
fact and opinion as to future events which the Company, at the date of the
issuance of the Business Plan, believed to be reasonable, but which the Company
cannot and does not assure or guarantee the attainment of in any manner. As of
the date hereof no facts have come to the attention of the Company which would,
in its opinion, require the Company to revise or amplify the assumptions
underlying such projections and other estimates or the conclusions derived
therefrom. The Company has previously furnished to the Purchasers true and
complete copies of its annual reports on Form 10-K for its fiscal years ended
December 31, 1985, 1986 and 1987 (the "10-Ks") and of its quarterly reports on
Form 10-Q for its fiscal quarters ended March 30, June 30 and September 30, in
each of such fiscal years and for the fiscal year ended December 31, 1988 (the
"10-Qs") as filed with the Securities and Exchange Commission (the "SEC").
Neither the 10-Ks, the 10-Qs, nor any other documents filed by the Company with
the SEC, as of the dates they were respectively filed, contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading. Each of the 10-Ks
and 10-Qs complied with all applicable rules of the SEC.

         SECTION 2.20 Offering of the Notes, the Warrants, the Common Conversion
Shares, the Preferred Conversion Shares and the Preferred Shares. Neither the
Company nor any person authorized or employed by the Company as agent, broker,
dealer or otherwise in connection with the offering or sale of the Notes, the

Preferred Shares or any security of the Company similar to the Notes, the
Warrants, the Common Conversion Shares, the Preferred Conversion Shares or the
Preferred Shares has offered the Notes, the Warrants, the Common Conversion
Shares, the Preferred Conversion Shares or the Preferred Shares or any such
similar security for sale to, or solicited any offer to buy the Notes, the
Warrants, the Common Conversion Shares, the Preferred Conversion Shares or the
Preferred Shares or any such similar security from, or otherwise approached or
negotiated with respect thereto with, any person or persons, and neither the
Company nor any person acting on its behalf has taken or will take any other
action (including, without limitation, any offer, issuance or sale of any
security of the Company under circumstances which might require the integration
of such security with the Notes, the Warrants, the Common Conversion Shares, the
Preferred Conversion Shares or the Preferred Shares under the Securities Act or
the rules and regulations of the Commission thereunder), in either case so as to
subject the offering, issuance or sale of the Notes, the Warrants, the Common
Conversion Shares, the Preferred Conversion Shares or the Preferred Shares to
the registration provisions of the Securities Act.

         SECTION 2.21 Brokers. The Company has no contract, arrangement or

and the total compensation anticipated to be paid to each such person by the
Company and its subsidiaries in 1989. None of such persons has an employment
agreement or understanding, whether oral or written, with the Company or any of
its subsidiaries, which is not terminable on notice by the Company or such
subsidiary without cost or other liability to the Company or such subsidiary.

         SECTION 2.23 Transactions With Affiliates. No director, officer,
employee or holder of five (5%) percent or more of the outstanding Common Stock
of the Company, or member of the family of any such person, or any corporation,
partnership, trust or other entity in which any such person, or any member of
the family of any such person, has a substantial interest or is an officer,
director, trustee, partner or holder of more than 5% of the outstanding capital
stock thereof, is a party to any transaction with the Company, including any
contract, agreement or other arrangement providing for the employment of,
furnishing of services by, rental of real or personal property from or otherwise
requiring payments to any such person or firm.

         SECTION 2.24 Employees. Each of the officers of the Company, each key
employee and each other employee now employed by the Company who has access to
confidential information of the Company has executed an Employment Agreement
substantially in the form of Exhibit G (collectively, the "Employment
Agreements"), and such agreements are in full force and effect. No officer or
key employee of the Company has advised the Company (orally or in writing) that
he intends to terminate employment with the Company. The Company has complied in
all material respects with all applicable laws relating to the employment of
labor, including provisions relating to wages, hours, equal opportunity,
collective bargaining and the payment of Social Security and other taxes, and
with the Employee Retirement Income Security Act of 1974, as amended.

         SECTION 2.25 U.S. Real Property Holding Corporation. The Company is not
now and has never been a "United States real property holding corporation", as
defined in Section 897(c)(2) of the Code and Section 1.897-2(b) of the
Regulations promulgated by the Internal Revenue Service.

         SECTION 2.26 Authorization of Stockholders' Meeting. The Board of
Directors of the Company has done all such things and taken all such action as
is necessary under the laws of the State of New York, the Charter, the By-laws
of the Company, and any agreement, indenture or instrument to which the Company
is a party or by which it is bound, to approve the Charter Amendment, to
recommend and submit the Charter Amendment to the stockholders for their
approval at the Stockholders' Meeting and to call the Stockholders' Meeting for
the purpose of approving the Charter Amendment.

for a period of thirty (30) days, to purchase all of such securities for cash at
an amount equal to the price or other consideration for which such securities
are to be issued; provided, however, that the first refusal rights of the
Purchasers pursuant to this Section 5.02 shall not apply to securities issued
(A) upon conversion of any of the notes or the Preferred Conversion Shares or
exercise of any of the Warrants, (B) as a stock dividend or upon any subdivision
of shares of Common Stock, provided that the securities issued pursuant to such
stock dividend or subdivision are limited to additional shares of Common Stock,
(C) pursuant to subscriptions, warrants, options, convertible securities, or
other rights which are listed in Schedule IV as being outstanding on the Closing
Date, (D) solely in consideration for the acquisition (whether by merger or
otherwise) by the Company or any of its subsidiaries of all or substantially all
of the stock or assets of any other entity, (E) pursuant to a firm commitment
underwritten public offering, (F) pursuant to the exercise of options to
purchase Common Stock granted to employees of the Company, not to exceed in the


<PAGE>
                                      -34-


aggregate 500,000 shares (appropriately adjusted to reflect stock splits, stock
dividends, combinations of shares and the like with respect to the Common Stock)
less the number of shares (as so adjusted) issued pursuant to options
outstanding on the date of this Agreement and listed in Schedule IV pursuant to
clause (C) above (the shares exempted by this clause (F) being hereinafter
referred to as the "Reserved Employee Shares"), and (G) upon the exercise of any
right which was not itself in violation of the terms of this Section 5.02. The
Company's written notice to the Purchasers shall describe the securities
proposed to be issued by the Company and specify the number, price and payment
terms. Each Purchaser may accept the Company's offer as to the full number of
securities offered to it or any lesser number, by written notice thereof given
by it to the Company prior to the expiration of the aforesaid thirty (30) day
period, in which event the Company shall promptly sell and such Purchaser shall
buy, upon the terms specified, the number of securities agreed to be purchased
by such Purchaser. Notwithstanding the foregoing, if the Purchasers agree, in
the aggregate, to purchaser more than the full number of securities offered by
the Company, then each Purchaser accepting the Company's offer shall first be
allocated the lesser of (i) the number of securities which such Purchaser agreed
to purchase and (ii) the number of securities as is equal to the full number of
securities offered by the Company multiplied by a fraction, the numerator of
which shall be the number of shares of Common Stock held by such Purchaser as of
the date of the Company's notice of offer (treating such Purchaser, for the
purpose of such calculation, as the holder of the number of shares of Common
Stock which would be issuable to such Purchaser upon conversion, exercise or
exchange of all securities (including but not limited to the Preferred Shares)
held by such Purchaser on the date such offer is made, that are convertible,
exercisable or exchangeable into or for (whether directly or indirectly) shares
of Common Stock) and the denominator of which shall be the aggregate number of
shares of Common Stock (calculated as aforesaid) held on such date by all
Purchasers who accepted the Company's offer, and the balance of the securities
(if any) offered by the Company shall be allocated among the Purchasers
accepting the Company's offer in proportion to their relative equity ownership
interests in the Company (calculated as aforesaid), provided that no Purchaser
shall be allocated more than the number of securities which such Purchaser
agreed to purchase and provided further that in cases covered by this sentence
all Purchasers shall be allocated among them the full number of securities
offered by the Company. The Company shall be free at any time prior to ninety
(90) days after the date of its notice of offer to the Purchasers, to offer and
sell to any third party or parties the number of such securities not agree by
the Purchasers to be purchased by them, at a price and on payment terms no less
favorable to the Company than those specified in such notice of offer to the
Purchasers. However, if such third party sale or sales are not consummated
within such ninety (90) day period, the Company shall not sell such securities
as shall not have been purchased within such period without again complying with
this Section 5.02.

         SECTION 5.03 Reserve for Preferred shares, Common Conversion Shares and
Preferred Conversion Shares. The Company shall at all time reserve and keep
available out of its authorized but unissued shares of Common Stock and, upon

Amendment with the Secretary of State of the State of New York, out of its
authorized but unissued shares of Preferred Stock, for the purpose of effecting
the exercise of the Warrants and the conversion of the Preferred Shares and the
Notes, and otherwise complying with the terms of this Agreement, such number of
its duly authorized shares of Common Stock and Preferred Stock as shall be
sufficient to effect the exercise of the Warrants and the Conversion of the
Preferred Shares and Notes, from time to time outstanding or otherwise to comply
with the terms of this Agreement. If at any time the number of authorized but
unissued shares of Common Stock and/or Preferred Stock shall not be sufficient
to effect the exercise of the Warrants and the conversion of the Preferred
Shares and the Notes, or otherwise to comply with the terms of this Agreement,
the Company will forthwith take such corporate action as may be necessary to
increase its authorize but unissued shares of Common Stock and/or Preferred
Stock to such number of shares as shall be sufficient for such purposes. The
Company will obtain any authorization, consent, approval or other action by or
make any filing with any court or administrative body that may be required under

also maintain in effect a "key person" life insurance policy, payable to the
Company, on the life of Kennard H. Morganstern (so long as he remains an
employee of the Company), in the amount of $1,000,000. The Company shall not
cause or permit any assignment or change in beneficiary and shall not borrow
against any such policy. If requested by Purchasers holding at least a majority
of the outstanding Notes and Warrants, the Company will add one designee of such
Purchasers as a notice party for each such policy and shall request that the
issuer of each policy provide such designee with ten (10) days' notice before
such policy is terminated (for failure to pay premiums or otherwise) or assigned
or before any change is made in the beneficiary thereof.

         SECTION 5.06 Inspection, Consultation and Advice. The Company shall
permit and cause any subsidiary which it may create to permit each Purchaser and
such persons as it may designate, at such Purchaser's expense, to visit and
inspect any of the properties of the Company and any such subsidiary, examine
their books and take copies and extracts therefrom, discuss the affairs,
finances and accounts of the Company and any such subsidiary with their
officers, employees and public accountants (and the Company hereby authorizes
said accountants to discuss with such Purchaser and such designees 


<PAGE>
                                      -36-

stock of the Company or any subsidiary which it may create, member of the family
of any such person, or any corporation, partnership, trust or other entity in

Preferred Shares or its designee to have one representative attend each meeting
of the Board of Directors of the Company and each meeting of any committee
thereof and to participate in all discussions during each such meeting. The
Company shall send to each such Purchaser and designee the notice of the

payable), without presentment, demand, protest or further notice of any kind,
all of which are hereby expressly waived by the Company.

         SECTION 6.02 Annulment of Defaults. Section 6.01 is subject to the
condition that, if at any time after the principal of any of the Notes shall

of the monies so due, or any thereof, shall have been entered, all arrears of
interest upon all the Notes and all other sums payable under the Notes and under
this Agreement (except the principal of the Notes which by such declaration
shall have become payable) shall have been duly paid, and every other default

                                   SCHEDULE II

                               Disclosure Schedule

         Section 2.05. The loss for the nine months ended September 30, 1988 was
$164,370. The estimated loss for the year will be approximately $400,000.

         Section 2.06. Since September 30, 1988, the Company has redeemed the
outstanding shares of Class A and Class B stock; has issued notes for $550,000
held by Bernard Livingston ($400,00), Constance K. Livingston ($100,000) and
Michael Morris ($50,000), maturing December 31, 1989 to replace notes which
matured December 31, 1988; has authorized the issuance of warrants to purchase
545,715 shares of common stock at $3.50 per share; has agreed to pay Weck
$260,000 on an account payable and to pay Medical Investment Associates $250,000
and Robert Liebowitz $50,000 in repayment of loans which were due December 31,
1988 and were extended by oral agreement to January 31, 1989; has negotiated
with Bank of New York for a new loan agreement, with Norstar Bank for a line of
credit and a term loan agreement, and with an investing client of Michael Morris
for a loan of $200,000. The Norstar Bank loans would require payment of Bank of
New York's loan and transfer of collateral from that bank to Norstar.

         Section 2.07. The only outstanding matters in litigation are:

                (1) McKenzie Associates, Inc. vs. General Sterilization
Services, Inc. (now the Company) and D.H. Blair, Inc. commenced in 1982 in The
Supreme Court of the State of New York, County of Nassau. The Company and D.H.
Blair Co., Inc. were named as defendants in an action which commenced August 17,
1983 by an investment advisor alleging failure to pay for services rendered,
breach of agreement and a conspiracy to deprive plaintiff of monies and Company
stock, and claiming damages in the amount of $112,500. The Company has agreed to
indemnify D.H. Blair & Co., Inc. for damages suffered by reason of this action.
Special counsel to the Company is of the opinion that the likelihood of an
unfavorable outcome in this litigation is remote.

                (2) Shamrock Technologies, Inc. vs. Medical Sterilization, Inc.
and Robert S. Luniewski, commenced in 1988 in the United States District Court,
Eastern District of New York, Civil Action No. 88-1681. The Company and Robert
S. Luniewski, its Vice-President, were named as defendants in an action which
commenced on June 3, 1988 by a Company alleging patent infringement and breach
of an Employment Agreement and a Trade Secret Agreement. The Complainant is
seeking damages and a permanent injunction from processing by methods which
allegedly infringed the patent and violated trade secrets. Special patent
counsel to the Company is of the opinion that the compliant is without merit.

         Section 2.08.  See Section 2.07 (2) above.


<PAGE>
                                      -49-


         Section 2.09. The loan owed to the Bank of New York is collateralized
by the Company's accounts receivable, surgical instruments and containers. The
loans owed to Weck are collateralized by steam and gas sterilizers and
ultrasonic and tunnel washers and second lien on the collateral given to the
Bank of New York.

         Section 2.14. The Company has no patents, patent rights, etc.

         Section 2.14. The Company has already disclosed the Shamrock

         Section 2.19. In the Company's Business Plan for 1989, there is a
reference to "A Business Opportunity." In the Profit & Loss for 1989 the Company
shows revenues and expenses relating to "Soft-Pack." There are no agreements
executed regarding this product and service, although the parties orally agreed
to proceed. The failure to proceed at this time would use the revenues and
expenses to be delayed.

         Section 2.20. The Company has discussed the issuance of notes to two
other parties including the client of Michael Morris. No agreement has been
rescheduled with either.

         Section 2.22. The officers of the Company and their salaries for 1989
are:

        Name                              Position                  Salary

dated as of December 30, 1989 between Medical Sterilization, Inc., a New York

Schedule I (individually a "Purchaser" and collectively the "Purchasers").
         WHEREAS, the Company wishes to issues and sell to the Purchasers its
Series A Convertible Preferred Stock ("Preferred Stock"), and its Common Stock
Purchase Warrants ("Warrants"); and
         WHEREAS, the Purchasers, severally, wish to purchase the Preferred
Stock and Warrants on the terms and subject to the conditions set forth in this
Agreement;
         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained in this Agreement, the parties agree as follows:

                                    ARTICLE I

         PURCHASE, SALE AND TERMS OF PREFERRED STOCK AND WARRANTS

         SECTION 1.01 The Preferred Stock. The Company has authorized the
issuance and sale to the Purchasers and others of the Company's Preferred Stock
in the original principal amount of no more than $2,000,000. The Preferred Stock
shall be substantially in the form set forth in Exhibit A hereto and is herein
referred to as Preferred Stock, which term shall also include any Preferred
Stock delivered in exchange or replacement therefor.

         SECTION 1.02 The Warrants. The Company has also authorized the issuance
and sale to the Purchasers and others of the Company's Common Stock Purchase
Warrants for the purchase (subject to adjustment as provided therein) of an
aggregate of 666,667 shares of the Company's Common Stock, $.01 par value (the
"Common Stock"). The Warrants shall be substantially in the form set forth in
Exhibit B hereto and are herein referred to individually as a "Warrant" and
collectively as the "Warrants," which terms shall also include any warrants
delivered in exchange or replacement therefor.

         SECTION 1.03 Purchase and Sale of the Preferred Stock and Warrants.

                  (a) The Closing. The Company agrees to issue and sell to each
Purchaser, and, subject to and in reliance upon the representations, warranties,
terms and conditions of this Agreement, each Purchaser agrees to purchase, the
principal amount of the Preferred Stock and Warrants for the purchase of the
number of shares of Common Stock set forth opposite the name of such Purchaser
under the headings "Shares of Preferred Stock" and "Warrant Shares,"
respectively, on Schedule I, at the aggregate purchase price set forth opposite
the name of such Purchaser under the heading "Aggregate Purchaser Price" on
Schedule I. Such purchase and sale shall take place at a closing (the "Closing")
to be held at the offices of Murtagh, Cohen & Byrne, 1122 Franklin Avenue,
Garden City, New York, on December 29, 1989 at 10:00 a.m., or at such other
location, date and time as may be agreed upon by the Purchasers and the Company
(such date and time being called the "Closing Date"). At the Closing the Company

Schedule I and Warrants, registered in the 



<PAGE>

of such Purchaser under the heading "Warrant Shares" on Schedule I. As payment
in full for the Preferred Stock and Warrants being purchased under this
Agreement, and against delivery of the Preferred Stock and Warrants as
aforesaid, on the Closing Date each Purchaser shall deliver to the Company a

Purchaser under the heading "Aggregate Purchase Price" on Schedule I, or shall
transfer such sum to the account of the Company by wire transfer, or shall
acknowledge as "Paid" money owed by the Company to such Purchaser in such
amount.

                  (b) Allocation of Purchase Price. The Company and the
Purchasers, having adverse interests and as a result of arm's length bargaining,
agree that (i) neither the Purchasers nor any of their respective partners, in
the case of a partnership, have rendered or have agreed to render any services
to the Company in connection with this Agreement or the issuance of the
Preferred Stock and Warrants; and (ii) the Warrants are not being issued as
compensation.

Preferred Stock and Warrants and the issuance and delivery of the Common
Conversion Shares upon exercise of the Warrants and the issuance and delivery of
the Preferred Conversion Shares upon conversion of the Preferred Shares have
been duly authorized by all requisite corporate action and will not violate any
provision of law, any order of any court or other agency of government, the
Certificate of Incorporation, or the By-laws of the Company, as amended, or any
provision of any indenture, agreement or other instrument to which the Company
or any of its properties or assets is bound, or conflict with, result in a
breach of or constitute (with due notice of lapse of time or both) a default
under any such indenture, agreement or other instrument, or result in the
creation or imposition of any lien, charge, restriction, claim or encumbrance of
any nature whatsoever upon any of the properties or assets of the Company. No
provision of the Stock Restriction Agreement violates, conflicts with, results
in a breach of or constitutes (with due notice of lapse of time or both) a
default under any indenture, agreement or other instrument to which the Company
is bound or, to the best of the Company's knowledge, any other indenture,
agreement or instrument (regardless, in each such case, of whether any such
violation, conflict, breach or default relates to the Company or to another
party to any such indenture, agreement or other instrument.)

                  (b) The Preferred Stock and the Warrants have been duly
authorized and, when issued in accordance with this Agreement, will be validly
issued, with no personal liability attaching to the ownership thereof and will

through the Company except as set forth in the Registration Rights Agreement.
Neither the issuance, sale or delivery of the Preferred Stock or the Warrants
nor the issuance or delivery of the Common Conversion Shares or the Preferred
Conversion Shares is subject to any preemptive right of shareholders of the
Company or to any right of first refusal or other right in favor of any person.

<PAGE>
                                       -4-


and the Stock Restriction Agreement, when executed and delivered in accordance
with this Agreement, will constitute the legal, valid and binding obligations of
the Company, enforceable in accordance with their respective terms.

         SECTION 2.04 Authorized Capital Stock. The authorized capital stock of
the Company consists of 10,000,000 shares of Common Stock, and 3,000,000 shares
of Preferred Stock, issuable in series, par value $.01 per share. Immediately

warrants, options, convertible securities, and other rights (contingent or
other) to purchase or otherwise acquire equity securities of the Company, and
the number of shares of Common Stock, and the number of such subscriptions,
warrants, options, convertible securities, and other such rights held by each,
are as set forth in the attached Schedule IV. The designations, powers,
preferences, rights, qualifications, limitations and restrictions in respect of
the Common Stock and the Preferred Stock are as set forth in the Restated
Certificate of Incorporation, a copy of which is attached as Exhibit C, and in
Exhibit D and in the Amendment to the Restated Certificate of Incorporation, a
copy of which is attached as Exhibit H, and all such designations, powers,
preferences, rights, qualifications, limitations and restrictions are valid,
binding and enforceable in accordance with all applicable laws. Except as set
forth in the attached Schedule IV, (i) no person owns of record or is known to
the Company to own beneficially five (5%) percent or more of the outstanding
Common Stock, (ii) no subscription, warrant, option, convertible security, or
other right (contingent or other) to purchase or otherwise acquire equity
securities of the Company is authorized or outstanding and (iii) there is no
commitment by the Company to issue shares, subscriptions, warrants, options,
convertible securities, or other such rights or to distribute to holders of any
of its equity securities, or other such rights or to distribute to holders of
any of its equity securities any evidence of indebtedness or asset. Except as
provided for in the Restated Certificate of Incorporation or as set forth in the
attached Schedule IV, the Company has no obligation (contingent or other) to
purchase, redeem or otherwise acquire any of its equity securities or any
interest therein or to pay any dividend or make any other distribution in
respect thereof. Except for the Stock Restriction Agreement, to the best of the
Company's knowledge there are no voting trusts or agreements, shareholders'
agreements, pledge agreements, buy sell agreements, rights of first refusal,
preemptive rights or proxies relating to any securities of the Company or any of
its subsidiaries (whether or not the Company or any of its subsidiaries is a
party thereto). All of the outstanding securities of the Company were issued in
compliance with all applicable Federal and state securities laws.

respectively. Since the date of the Balance Sheet, (i) there has been no change
in the assets, liabilities or financial condition of the Company from that
reflected in the Balance Sheet except for changes in the ordinary course of
business which in the aggregate have not been materially adverse except that the
Company anticipates a loss for the fourth quarter of approximately $117,000 and
for the year of approximately $400,000 and (ii) none of the business, prospects,
financial condition, operations, property or affairs of the Company has been

commitment (contingent or otherwise) to do any of the foregoing.

         SECTION 2.07 Litigation; Compliance with Law. There is no (i) action,
suit, claim, proceeding or investigation pending or, to the best of the
Company's knowledge, threatened against or affecting the Company, at law or in
equity, or before or by any Federal, state, municipal or other governmental
department, commission, board, bureau, agency or instrumentality, domestic or
foreign, (ii) arbitration proceeding relating to the Company pending under
collective bargaining agreements or otherwise or (iii) governmental inquiry
pending or, to the best of the Company's knowledge, threatened against or
affecting the Company (including without limitation any inquiry as to the
qualification of the Company to hold or receive any license or permit), and
there is no basis for any of the foregoing. The Company has not received 


<PAGE>
                                      -6-


any opinion or memorandum or legal advice from legal counsel to the effect that
it is exposed, from a legal standpoint, to any liability or disadvantage which
may be material to its business, prospects, financial condition, operations,
property or affairs. The Company is not in default with respect to any order,
writ, injunction or decree known to or served upon the Company of any court or
of any Federal, state, municipal or other governmental department, commission,
board, bureau, agency or instrumentality, domestic or foreign. There is no
action or suit by the Company pending or threatened against others. The Company
has complied with all laws, rules, regulations and orders applicable to its
business, operations, properties, assets, products and services, and the Company
has all necessary permits, licenses and other authorizations required to conduct
its business as conducted and as proposed to be conducted. There is no existing
law, rule, regulation or order, whether Federal or state, which would prohibit
or restrict the Company from, or otherwise materially adversely affect the
Company in, conducting its business in any jurisdiction in which it is now
conducting business or which it proposes to conduct business.

         SECTION 2.08 Proprietary Information of Third Parties. To the best of
the Company's knowledge, no third party has claimed or has reason to claim that
any person employed by or affiliated with the Company has (a) violated or may be
violating any of the terms or conditions of his employment, non-competition or
non-disclosure agreement with such third party, (b) disclosed or may be
disclosing or utilized or may be utilizing any trade secret or proprietary
information or documentation of such third party or (c) interfered or may be
interfering in the employment relationship between such third party and any of
its present or former employees. No third party has requested information from
the Company which suggests that such a claim might be contemplated. To the best
of the Company's knowledge, no person employed by or affiliated with the Company
has employed or proposes to employ any trade secret or any information or
documentation proprietary to any former employer, and to the best of the
Company's knowledge, no person employed by or affiliated with the Company has
violated any confidential relationship which such person may have had with any
third party, in connection with the development, manufacture or sale of any
product or proposed product or the development or sale of any service or
proposed service of the Company, and the Company has no reason to believe there
will be any such employment or violation. To the best of the Company's
knowledge, none of the execution or delivery of this Agreement, or the carrying
on of the business of the Company as officers, employees or agents by any
officer, director or key employee of the Company, or the conduct or proposed
conduct of the business of the Company, will conflict with or result in a breach
of the terms, conditions or provisions of or constitute a default under any
contract, covenant or instrument under which any such person is obligated.

         SECTION 2.09 Title to Properties. The Company has good and marketable
title to its properties and assets reflected on the Balance Sheet or acquired by
it since the date of the Balance Sheet (other than properties and assets
disposed of in the ordinary course of business since the date of the Balance
Sheet), and all such properties and assets are free and clear of mortgages,
pledges, security interests, liens, charges, claims, restrictions and other
encumbrances, except for liens for or current taxes not yet due and payable and
minor imperfections of title, if any, not material in nature or amount and not
materially detracting from the value or impairing the use of the property
subject thereto or impairing the operations or proposed operations of the
Company.

                                      -7-


         SECTION 2.10 Leasehold Interests. Each lease or agreement to which the
Company is a party under which it is a lessee of any property, real or personal,
is a valid and subsisting agreement without any default of the Company
thereunder and, to the best of the Company's knowledge, without any default
thereunder of any other party thereto. No event has occurred and is continuing
which, with due notice or lapse of time or both, would constitute a default or
event of default by the Company under any such lease or agreement or, to the
best of the Company's knowledge, by any other party thereto. The Company's
possession of such property has not been disturbed and, to the best of the
Company's knowledge, no claim has been asserted against the Company adverse to
its rights in such leasehold interests.

         SECTION 2.11 Insurance. The Company holds valid policies covering all
of the insurance required to be maintained by it under Section 5.05.

         SECTION 2.12 Taxes. The Company has filed all tax returns, Federal,
state, county and local, required to be filed by it, and the Company has paid
all taxes shown to be due by such returns as well as all other taxes,
assessments and governmental charges which have become due or payable, including
without limitation all taxes which the Company is obligated to withhold from
amounts owing to employees, creditors and third parties. All such taxes with
respect to which the Company has become obligated pursuant to elections made by
the Company in accordance with generally accepted practice have been paid and
adequate reserves have been established for all taxes accrued but not yet
payable. The Federal income tax returns of the Company have never been audited
by the Internal Revenue Service. No deficiency assessment with respect to or
proposed adjustment of the Company's Federal, state, county or local taxes is
pending or, to the best of the Company's knowledge, threatened. There is no tax
lien, whether imposed by any Federal, state, county or local taxing authority,
outstanding against the assets, properties or business of the Company. Neither
the Company nor any of its shareholders has ever filed (a) an election pursuant
to Section 1362 of the Internal Revenue Code of 1986, as amended (the "Code"),
that the Company be taxes as an S corporation or (b) consent pursuant to Section
341(f) of the Code, relating to collapsible corporations. The Company's net
operating losses for Federal income tax purposes, as set forth in the financial
statements referred to in Section 2.05, are not subject to any limitations
imposed by Section 382 of the Code and the full amount of such net operating
losses are available to offset the taxable income of the Company for the current
fiscal year and, to the extent not so used, succeeding fiscal years.
Consummation of the transactions contemplated by this Agreement or by any other
agreement, understanding or commitment (contingent or otherwise) to which the
Company is a party or by which it is otherwise bound will not have the effect of
limiting the Company's ability to use such net operating losses in full to
offset such taxable income.

         SECTION 2.13 Other Agreements. Except as set forth in the attached
Schedule V(A), the Company is not a party to or otherwise bound by any written
or oral contract or instrument or other restriction which individually or in the
aggregate could materially adversely affect the business, prospects, financial
condition, operations, property or affairs of the Company. Except as set forth
in the attached Schedule V(B), the Company is not a party to or otherwise bound
by any written or oral:


<PAGE>
                                      -8-


                  (a) distributor, dealer, manufacturer's representative or sale
agency contract or agreement which is not terminable on less than ninety (90)
days' notice without cost or other liability to the Company (except for
contracts which, in the aggregate, are not material to the business of the
Company);

                  (b) sales contract which entitles any customer to a rebate or
right of set-off, to return any product to the Company after acceptance thereof
or to delay the acceptance thereof, or which varies in any material respect from
the Company's standard form contracts;

                  (c) contract with any labor union (and, to the knowledge of
the Company, no organizational effort is being made with respect to any of its
employees);

                  (d) contract or other commitment with any supplier containing
any provision permitting any party other than the Company to renegotiate the
price or other terms, or containing any pay-back or other similar provision,
upon the occurrence of a failure by the Company to meet its obligations under
the contract when due or the occurrence of any other event;

                  (e) contract for the future purchase of fixed assets or for
the future purchase of materials, supplies or equipment in excess of its normal
operating requirements;

                  (f) contract for the employment of any officer, employee or
other person (whether of a legally binding nature or in the nature of informal
understandings) on a full-time or consulting basis which is not terminable on
notice without cost or other liability to the Company, except normal severance
arrangements and accrued vacation pay;

with no equity feature), offer to each Purchaser by written notice the right,
for a period of thirty (30) days, to purchase all of such securities for cash at

Purchasers pursuant to this Section 5.02 shall not apply to securities issued

to purchase and (ii) the number of securities as is equal to the full number of
securities offered by the Company multiplied by a fraction, the numerator of

the date of the Company's notice of offer (treating such Purchaser, for the
purpose of such calculation, as the holder of the number of shares of Common
Stock which would be issuable to such Purchaser upon conversion, exercise or
exchange of all securities (including but not limited to the Preferred Stock)
held by such Purchaser on the date such offer is made, that are convertible,
exercisable or exchangeable into or for (whether or directly or indirectly)
shares of Common Stock) and the denominator of which shall be the aggregate
number of shares of Common Stock (calculated as 


<PAGE>
                                      -21-

offer, and the balance of the securities (if any) offered by the Company shall
be allocated among the Purchasers accepting the Company's offer in proportion to
their relative equity ownership interests in the Company provided that no
Purchasers accepting the Company's offer in proportion to their relative equity
ownership interests in the Company (calculated as aforesaid), provided that no
Purchaser shall be allocated more than the number of securities which such
Purchaser agreed to purchase and provided further that in cases covered by this

offer and sell to any third party or parties the number of such securities not
agreed by the Purchasers to be purchased by them, at a price and on payment
terms no less favorable to the Company than those specified in such notice of

necessary to increase its authorized but unissued shares of Common Stock to such

                               Disclosure Schedule

         Section 2.05. The loss for the nine months ended September 30, 1989 was
$282,620. The estimated loss for the year ended December 31, 1989 will be
approximately $400,000.

         Section 2.06. Since September 30, 1989, the Company borrowed the sum of
$500,000 from Apple Bank for Savings pursuant to a Term Loan Note and Security
Agreement dated November 2, 1989 and used the proceeds to purchase from Elkcom
Leasing, Inc. the Radiation Dynamics 4500/34/1220 In Line Dynamitron and
accessory equipment which the Company had leased from Elkcom Leasing, Inc. As
security for said loan, the Company pledged and granted a security interest in
the Dynamitron to Apple Bank for Savings.

         Section 2.07. The only outstanding matters in litigation are:

         (1) McKenzie Associates, Inc. vs. General Sterilization Services, Inc.
(now the company) and D.H. Blair, Inc. in the Supreme Court of the State of New
York, County of Nassau. The Company and D.H. Blair & Co., Inc. were named as
defendants in an action which commenced August 17, 1983 by an investment advisor
alleging failure to pay for services rendered, breach of agreement and a
conspiracy to deprive plaintiff of monies and Company stock, and claiming
damages in the amount of $112,500. The Company has agreed to indemnify D.H.
Blair & Co., Inc. for damages suffered by reason of this action. The Plaintiff
has not proceeded with this action and special counsel to the Company is of the
opinion that the likelihood of an unfavorable outcome in this litigation is
remote.

         (2) The Company and Robert S. Luniewski, its Senior Vice President,
were named as defendants in an action which was commenced on June 3, 1988 in the
United States District Court, Eastern District of New York, by Shamrock
Technologies, Inc. alleging patent infringement and breach of an Employment
Agreement and a Trade Secret Agreement. The Complainant is seeking damages and a
permanent injunction from processing by methods which allegedly infringed the
plaintiff's patents and violated trade secrets. A motion for Summary Judgment
was granted in favor of the plaintiff on August 8, 1989 declaring that the
plaintiff's patents were valid and enforceable and that the Company's processes
infringed the patents. The Company was enjoined as of September 3, 1989 from
using processes and equipment which infringe the patents. On appeal of the order
has been filed with the Federal Circuit Court of Appeals in Washington, D.C.
Special counsel to the Company, Kane, Dalsimer, Sullivan, Kurucz, Levy, Eisele &
Richard, is of the opinion that the judgment will be reversed on appeal and
further that the Company is now processing teflon by methods which do not
infringe the patents.

         Section 2.08.  See Section 2.07(2) above.

         Section 2.09. The Revolving Credit loan owed to Apple Bank for Savings
is collaterilized by the Company's accounts receivable, surgical instruments and
containers. See

Section 2.06 above regarding other collateral held by Apple Bank. The loans owed
to Weck are collateralized by steam and gas sterilizers and ultrasonic and
tunnel washers and second lien on the collateral given to the Apple Bank.

         Section 2.12. The Sales Tax Department of the New York State Department
of Taxation and Finance has advised the Company that a sales tax audit and
assessment may be made relating to the purchases of medical equipment which are
in turn leased to hospitals. It is the opinion of the Company and its auditors
that the Company is exempt from payment of sales taxes on equipment which it
then leases.

         Section 2.13(b). The Company has agreements relating to outstanding
loans from Bernard S. Livingston ($400,000), Constance K. Livingston ($100,000),
Michael L. Morris ($50,000), Kabela, Inc. ($200,000), Dr. William C. Cartinhour,
Jr. ($500,000), Kennard H. Morganstern ($450,000), Harvey Cohen ($100,000), the
Apple Bank for Savings and Weck as previously set forth. Out of the proceeds of
this transaction, all loans will be paid off except Kennard H. Morganstern
($400,000), Harvey Cohen ($50,000), Apple Bank for Savings and Weck.

         Section 2.14. The Company has no patents, patent rights, etc. The
Company has already disclosed the Shamrock litigation. (See Section 2.07).

         Section 2.15. Employee loans may be granted for medical or other
emergency on approval of the President and Vice-president in an amount not
exceeding $500.

         Section 2.17. The Company is in default under its Loan Agreement with
Weck, a significant supplier, because it is not current in its interest
payments.

Preferred Stock shall vote together with all other classes and series of stock
of the corporation as a single class on all actions to be taken by the
stockholders of the Corporation. Each shares of Series A Convertible Preferred
Stock shall entitle the holder thereof to such number of votes per share on each
such action as shall equal the number of votes of Common Stock (including
fractions of a share) into which each share of Series A Convertible Preferred
Stock is then convertible.

            2B. Board Size. The Corporation shall not, without the written
consent or affirmative vote of the holders of at least two-thirds of the then
outstanding shares of Series A Convertible Preferred Stock, given in writing or
by vote at a meeting, consenting or voting (as the case may be) separately as a
series, increase the maximum number of directors constituting the Board of
Directors to a number in excess of election (11).

            2C. Board Seats. The holders of the Series A Convertible Preferred
Stock, voting as a separate series, shall be entitled to elect one (1) director
of the Corporation. The holders of the Common Stock, voting as a separate class,
shall be entitled to elect the remaining directors of the Corporation.
Notwithstanding the foregoing or anything else to the contrary provided in the
Restated Certificate of Incorporation, if the Corporation fails or refuses, for
any reason or for no reason, to redeem on the Redemption Date (as defined in
paragraph 7) all of the then outstanding shares of Series A Convertible
Preferred Stock in accordance with the terms and provisions of paragraph 7, the
holders of the Series A Convertible Preferred Stock, voting as a separate
series, shall be entitled to elect a majority of the directors of the
Corporation. At any meeting (or in a written consent in lieu thereof) held for
the purpose of electing directors, the presence in person or by proxy (or the
written consent) of the holders of a majority of the shares of Series A

<PAGE>
                                       -2-


declared, and shall be cumulative from the date of issuance of the Series A
Convertible Preferred Stock.


         4. Liquidation. Upon any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, the holders of the shares of
Series A Convertible Preferred Stock shall first be entitled, before any
distribution or payment is made upon any stock ranking on liquidation junior to

share plus, in the case of each shares, an amount equal to all Accruing

Preferred Stock being sometimes referred to as the "Liquidation Preference
Payment" and with respect to all shares of Series A Convertible Preferred Stock
being sometimes referred to as the "Liquidation Preference Payments". If upon
such liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, the assets to be distributed among the holders of
Series A Convertible Preferred Stock shall be insufficient to permit payment in
full to the holders of Series A Convertible Preferred Stock of the Liquidation
Preference Payments, then the entire assets of the Corporation to be so
distributed shall be distributed ratably among the holders of Series A
Convertible Preferred Stock. Upon any such liquidation, dissolution or winding
up of the Corporation, immediately after the holders of Series A Convertible
Preferred Stock shall have been paid in full the Liquidation Preference
Payments, the remaining net assets of the Corporation available for distribution
shall be distributed ratably among the holders of Series A Convertible Preferred
Stock being deemed, for such purpose, to be equal to the number of shares of

Convertible Preferred Stock is convertible immediately prior to the close of
business on the business day fixed for such distribution). Written notice of
such liquidation, dissolution or winding up, stating a payment date and the
place where said payments shall be made, shall be given by mail, postage
prepaid, or by telex to non-U.S. residents, not less than 20 days prior to the
payment date stated therein, to the holders of record of Series A Convertible
Preferred Stock, such note to be addressed to each such holder at its address as
shown by the records of the Corporation. The consolidation or merger of the
Corporation into or with any other entity or entitles which results in the
exchange of outstanding shares of the Corporation for securities or other
consideration issued or paid or caused to be issued or paid by any such entity
or affiliate thereof, and the sale or transfer by the Corporation of all or
substantially all its assets, shall be deemed to be a liquidation, dissolution
or winding up of the Corporation within the meaning of the provisions of this
paragraph 4. For purposes hereof, the Common Stock shall rank on liquidation
junior to the Series A Convertible Preferred Stock.


         5. Restrictions. At any time when shares of Series A Convertible
Preferred Stock are outstanding, except where the vote or written consent of the
holders of a greater number of shares of the Corporation is required by law or
by the Restated Certificate of Incorporation, and in addition to any other vote
required by law or the Restated Certificate of Incorporation, without the
approval of the holders of at least two-thirds of the then outstanding shares of
Series A Convertible Preferred Stock, given in writing or by vote at a meting,
consenting or voting (as the case may be) separately as a series, the
Corporation will not:

Convertible Preferred Stock or into shares of any other class or series of stock

Corporation, whether any such creation, authorization or increase shall be by
means of amendment to the Restated Certificate of Incorporation or by merger,
consolidation or otherwise;

            5B. Consent to any liquidation, dissolution or winding up of the
Corporation or consolidate or merger into or with any other entity or entities

or By-laws in a manner in which adversely affects the holders of Series A
Convertible Preferred Stock;

            5D. Purchase or set aside any sums for the purchase of, or pay any
dividend or make an distribution on, any shares of stock other than the Series A

Corporation who acquired such shares directly from the Corporation, if each such
purchase is made pursuant to contractual rights held by the Corporation relating

<PAGE>
                                       -4-


Convertible Preferred Stock) into such number of fully paid and nonassessable
shares of Common Stock as is obtained by (i) multiplying the number of shares of
Series A Convertible Preferred Stock so to be converted by $3.00 and (ii)
dividing the result by the conversion price of $3.00 per share or, in case an
adjustment of such price has taken place pursuant to the further provisions of
this paragraph 6, then by the conversion price as last adjusted and in effect at
the date any share or shares of Series A convertible Preferred Stock are
surrendered for conversion (such price, or such price as last adjusted, being
referred to as the "Conversion Price"). Such rights of conversion shall be
exercised by the holder thereof by giving written notice that the holder elects
to convert a stated number of shares of Series A Convertible Preferred Stock
into Common Stock and by surrender of a certificate or certificates for the
shares so to be converted to the corporation at its principal office (or such
other office or agency of the Corporation as the Corporation may designate by
notice in writing to the holders of the series A Convertible Preferred Stock) at

name or names as such holder may direct, a certificate or certificates for the
number of whole shares of Common Stock issuable upon the conversion of such
share or shares of Series A convertible Preferred Stock. To the extent permitted
by law, such conversion shall be deemed to have been effected and the Conversion
Price shall be determined as of the close of business on the date on which such
written notice shall have been received by the Corporation and the certificate
or certificates for such share or shares shall have been surrendered as
aforesaid, and at such time the rights of the holder of such share or shares of
Series A Convertible Preferred Stock shall cease, and the person or persons in
whose name or names any certificate or certificates for shares of Common Stock
shall be issuable upon such conversion shall be deemed to have become the holder
or holders of record of the shares represented thereby.


            6C. Fractional Shares; Dividends; Partial Conversion. No fractional
shares shall be issued upon conversion of Series a Convertible Preferred Stock
into Common Stock and no payment or adjustment shall be made upon any conversion
on account of any cash dividends on the Common Stock issued upon such
conversion. At the time of each conversion, the Corporation shall pay in cash an
amount equal to all dividends, excluding Accruing Dividends, accrued and unpaid
on the shares of Series A Convertible Preferred Stock surrendered for conversion
to the date upon which such conversion is deemed to take place as provide don
subparagraph 6B. In case the number of shares of Series A Convertible Preferred
Stock represented by the certificate or certificates surrendered pursuant to
subparagraph 6A exceeds the number of shares converted, the Corporation shall,
upon such conversion, execute and deliver to the holder, at the expense of the
corporation, a new certificate or certificates for the number of shares of
Series A Convertible Preferred Stock represented by the certificate or
certificates surrendered which are not to be converted. If any fractional share
of Common Stock would, except for the provisions of the first sentence of this

<PAGE>
                                       -5-


conversion, the Corporation, in lieu of delivering such fractional share, shall
pay to the holder surrendering the Series A Convertible Preferred Stock for
conversion an amount in cash equal to the current market price of such
fractional shares as determined in good faith by the Board of Directors of the
Corporation.

            6D. Adjustment of Price Upon Issuance of Common Stock. Except as
provided in subparagraph 6E, if and whenever the Corporation shall issue or
sell, or is, in accordance with subparagraph 6D(1) through 6D(7), deemed to have
issued or sold, any shares of Common Stock for a consideration per share less
than the Conversion Price in effect immediately prior to the time of such issue
or sale, then, forthwith upon such issue or sale, the Conversion Price shall be
reduced to the price at which the Corporation issued or sold, or is deemed to
have issued or sold, such shares of Common Stock.

        For purposes of this subparagraph 6D, the following subparagraphs 6D(1)
to 6D(7) shall also be applicable.

                  6D(1) Issuance of Rights or Options. In case at any time the
        Corporation shall in any manner grant (whether directly or by assumption
        in a merger or otherwise) any warrants or other rights to subscribe for
        or to purchase, or any options for the purchase of, Common Stock or any
        stock or security convertible into or exchangeable for common Stock
        (such warrants, rights or options being called "Options" and such
        convertible or exchangeable stock or securities being called
        "Convertible Securities") whether or not such Options or the right to
        convert or exchange any such Convertible Securities are immediately
        exercisable, and the price per share for which Common stock is issuable
        upon the exercise of such Options or upon the conversion or exchange of
        such Convertible Securities (determined by dividing (i) the total
        amount, if any, received or receivable by the Corporation as
        consideration for the granting of such Options, plus the minimum
        aggregate amount of additional consideration payable to the Corporation
        upon the exercise of all such Options, plus, in the case of such Options
        which relate to Convertible Securities, the minimum aggregate amount of
        additional consideration, if any, payable upon the issue or sale of such
        convertible Securities and upon the conversion or exchange thereof, by
        (ii) the total maximum number of shares of Common Stock issuable upon
        the exercise of such Options or upon the conversion or exchange of all
        such Convertible Securities issuable upon the exercise of such Options)
        shall be less than the Conversion Price in effect immediately prior to
        the time of the granting of such Options, then the total maximum number
        of shares of Common Stock issuable upon the exercise of such Options or
        upon conversion or exchange of the total maximum amount of such
        Convertible Securities issuable upon the exercise of such Options shall
        be deemed to have been issued for such price per share as of the date of
        gaining of such Options or the issuance of such Convertible Securities
        and thereafter shall be deemed to be outstanding. Except as otherwise
        provided in subparagraph 6D(3), no adjustment of the Conversion Price
        shall be made upon the actual issue of such Common Stock or of such
        Convertible Securities upon exercise of such Options or upon the actual
        issue of such Common Stock upon conversion or exchange of such
        Convertible Securities.

                  6D(2) Issuance of Convertible Securities. In case the
        Corporation shall in any manner issue (whether directly or by assumption
        in a merger or otherwise) or sell any Convertible Securities, whether or
        not the rights to exchange or convert any such Convertible Securities
        are immediately exercisable, and the price per share for which Common
        Stock is issuable upon such conversion or exchange (determined by
        dividing (i) the total amount received or receivable by the Corporation
        as consideration for the issue or sale of such Convertible Securities,
        plus the minimum aggregate amount of additional consideration, if any,
        payable to the Corporation upon the conversion or exchange thereof, by
        (ii) the total maximum number of shares of Common Stock issuable upon
        the conversion or exchange of all such Convertible Securities) shall be
        less than the Conversion Price in effect immediately prior to the time
        of such issue or sale, then the total maximum number of shares of Common
        Sock issuable upon conversion or exchange of all such Convertible
        Securities shall be deemed to have been issued for such price per share
        as of the date of the issue or sale of such Convertible Securities and
        thereafter shall be deemed to be outstanding, provided that (a) except 
        as otherwise provided in subparagraph 6D(3), no adjustment to the
        Conversion Price shall be made upon the actual issue of such Common
        Stock upon conversion or exchange of such Convertible Securities and (b)
        if any such issue or sale of such Convertible Securities is made upon
        exercise of any Options to purchase any such Convertible Securities for
        which adjustments of the Conversion price have been or are to be made
        pursuant to other provisions of this subparagraph 6D, not further
        adjustment of the conversion price shall be made by reason of such issue
        or sale.

                  6D(3) Change in Option Price or Conversion Rate. Upon the
        happening of any of the following events, namely, if the purchase price
        provided for in any Option referred to in subparagraph 6D(1), the
        additional consideration, if any, payable upon the conversion or
        exchange of any Convertible Securities referred to in subparagraph 6D(1)
        or 6D(2), or the rate at which Convertible Securities refereed to in
        subparagraph 6D(1) or 6D(2) are convertible into or exchangeable for
        Common Stock shall change at any time including, but not limited to,
        changes under or by reason of provisions designed to protect against
        dilution), the Conversion Price in effect at the time of such event
        shall forthwith be readjusted to the Conversion Price in effect at the
        time of such event shall forthwith be readjusted to the Conversion Price
        which would have been in effect such time had such Options or
        Convertible Securities still outstanding provided for such changed
        purchase price, additional consideration or conversion rate, as the case
        may be, the time initially granted, issued or sold, but only if as a
        result of such adjustment the Conversion Price then in effect hereunder
        is thereby reduce; and upon the expiration of any such Option or the
        termination of any such right to convert or exchange such Convertible
        Securities, the Conversion Price then in effect hereunder shall
        forthwith be increased to the Conversion Price which would have been in
        effect at the time of such expiration or termination of such Option or
        Convertible Securities, to the extent outstanding immediately prior to
        such expiration or termination, never been issued.


                  6D(4) Stock Dividends. In case the Corporation shall declare a
        dividend or make any other distribution upon any stock of the

<PAGE>
                                       -7-


        Stock (except for dividends or distributions upon the Common Stock),
        Options or Convertible Securities, any Common Stock, Options or
        Convertible Securities, as the case may be, issuable in payment of such
        dividend or distribution shall be deemed to have been issued or sold
        without consideration.


                  6D(5) Consideration for Stock. In case any shares of Common
        Stock, Options or Convertible Securities shall be issued or sold for
        cash, the consideration received therefor shall be deemed to be the
        amount received by the Corporation therefore, without deduction
        therefrom of any expenses incurred or any underwriting commissions or
        concessions paid or allowed by the Corporation in connection therewith.
        In case any shares of Common Stock, Options or Convertible Securities
        shall be issued or sold for a consideration other than cash, the amount
        of the consideration other than cash received by the Corporation shall
        be deemed to be the fair value of such consideration as determined in
        good faith by the Board of Directors of the Corporation, without
        deduction of any expenses incurred or any underwriting commissions for
        concessions paid or allowed by the Corporation in connection therewith.
        In case any Options shall be issued on connection with the issue and
        sale of other securities of the Corporation, together comprising one
        integral transaction in which no specific consideration is allocated to
        such Options by the parties thereof, such options shall be deemed to
        have been issued for such consideration as determined in good faith by
        the Board of Directors of the Corporation.


                  6D(6) Record Date. In case the Corporation shall take a record
        of the holders of its Common Stock for the purpose of entitling them (i)
        to receive a dividend or other distribution payable in Common Stock,
        Options or Convertible securities or (ii) to subscribe for or purchase
        Common Stock, Options or Convertible securities, then such record date
        shall be deemed to be the date of the issue or sale of the shares of
        Common stock deemed to have been issued or sold upon the declaration of
        such dividend or the making of such other distribution or the date of
        the granting of such right of subscription or purchase, as the case may
        be.

                  6D(7) Treasury Shares. The disposition of any shares of Common
        Stock owned or held by or for the account of the Corporation shall be
        considered an issue or sale of Common Stock for the purpose of this
        subparagraph 6D.

                  6E. Certain Issues of Common Stock Excepted. Anything herein
        to the contrary notwithstanding, the Corporation shall not be required
        to make any adjustment to the Conversion Price in the case of the
        issuance of up to an aggregate of 500,000 shares (appropriately adjusted
        to reflect the occurrence of any event described in subparagraph 6F) of
        Common Stock to directors, officers or employees of the Corporation in
        connection with their service as directors of the Corporation or their
        employment by the Corporation.

                  6F. Subdivision or Combination of Common Stock. In case the
        Corporation shall at any time subdivide (by any stock split, stock
        dividend or otherwise) its outstanding shares of Common Stock into a
        greater number of shares, the Conversion Price in effect 


<PAGE>
                                       -8-


        immediately prior to such subdivision shall be proportionately reduced,
        and, conversely, in case the outstanding shares of Common Stock shall be
        combined into a smaller number of shares, the Conversion Price in effect
        immediately prior to such combination shall be proportionality
        increased.

                  6G. Reorganization or Reclassification. If any capital
        reorganization or reclassification of the capital stock of the
        Corporation shall be effected in such a way that holders of Common Stock
        shall be entitled to receive stock, securities or assets with respect to
        or in exchange for Common Stock, then, as a condition of such
        reorganization or reclassification, lawful and adequate provisions shall
        be made whereby each holder of a share or shares of Series A Convertible
        Preferred Stock shall thereupon have the right to receive, upon the
        basis and upon the terms and conditions as provided herein and in lieu
        of the shares of Common Stock immediately theretofore receivable upon
        the conversion of such share or shares of Series A Convertible Preferred
        Stock, such shares of stock, securities or assets as may be issued or
        payable with respect to or in exchange for a number of outstanding
        shares of such Common Stock equal to the number of shares of such Common
        Stock immediately theretofore receivable upon such conversion had such
        reorganization or reclassification not taken place, and in any such case
        appropriate provisions shall be made with respect to the rights and
        interest of such holder to the end that the provisions hereof (including
        without limitation provisions for adjustments of the Conversion Price)
        shall thereafter be applicable, as nearly as may be, in relation to any
        shares of stock, securities or assets thereafter deliverable upon the
        exercise of such conversion rights.

                  6H. Failure to Redeem. If the Corporation fails, for any
        reason or for no reason, to redeem on the Redemption Date (as defined in
        paragraph 7) all of the then outstanding shares of Series A Convertible
        Preferred Stock in accordance with the terms and conditions of paragraph
        7, the Conversion Price then in effect shall be immediately reduced to
        an amount equal to 90% thereof. Thereafter until such redemption has
        been made in full in accordance with such terms and conditions, the
        Conversion Price shall be further reduced on the 90th day following the
        Redemption Ate and at the end of each 90-day period thereafter to an
        amount equal to 90% of the Conversion Price in effect immediately prior
        to each such reduction.

                  6I. Notice of Adjustment. Upon any adjustment of the
        Conversion Price, then and in each such case the Corporation shall given
        written notice thereof, by first class, mail, postage prepaid, or by
        telex to non-U.S. residents, addressed to each holder of shares of
        Series a Convertible Preferred Stock as the address of such holder as
        shown on the books of the corporation, which notice shall state the
        Conversion Price resulting from such adjustment, setting forth in
        reasonable detail the method upon which such calculation is based.

                  6J. Other Notices. In case at any time:

                                       -2-


dividends and distributions on any shares entitled to preference, and the
holders of which shall ordinarily, in the absence of contingencies, be entitled

lieu of or in addition to Common Stock, or which at any time shall be issuable
or shall have been issued in exchange for or in replacement of Common Stock or
Other Securities pursuant to Section 5 or otherwise.

        1. Exercise of Warrant.

           1.1 Full Exercise. This Warrant may be exercised in full by the
holder hereof by surrender of this Warrant, with the form of subscription at the
end hereof duly executed by such holder, to the Company at its principal office,
accompanied by payment in cash or by certified or official bank check payable to
the order of the Company, in the amount obtained by multiplying the number of
shares of Common Stock for which this Warrant is then exercisable by the
Purchase Price then in effect. The number of shares shall be obtained by (i)
multiplying the number of shares for which this Warrant is exercisable by $3.00
and (ii) dividing the result by the exercise price of $3.00 per share, or, in
case an adjustment of such price has taken place pursuant to the provisions of
Paragraph 5 hereof, then by the exercise price as last adjusted and in effect at
the date of exercise of this Warrant.

           1.2 Partial Exercise. This Warrant may be exercised in part by
surrender of this Warrant in the manner and at the place provided in subsection
1.1 except that the amount payable by the holder on such partial exercise shall
be the amount obtained by multiplying (a) the number of shares of Common Stock
designated by the holder in the subscription at the end hereof by (b) the
Purchase Price then in effect. On any such partial exercise the Company at its
expense will forthwith issue and deliver to or upon the order of the holder
hereof a new Warrant or Warrants of like tenor, in the name of the holder hereof
or as such holder (upon payment by such holder of any applicable transfer taxes)
may request, calling in the aggregate on the face or faces thereof for the
number of shares of Common Stock for which such Warrant or Warrants may still be
exercised.


           1.3 Company Acknowledgment. The Company will, at the time of the
exercise of the Warrant, upon the request of the holder hereof acknowledge in
writing its continuing obligation to afford to such holder any rights to which
such holder shall continue to be entitled after such exercise in accordance with
the provisions of this Warrant. If the holder shall fail to make any such
request, such failure shall not affect the continuing obligation of the Company
to afford to such holder any such rights.

                                       -3-


           1.4 Trustee for Warrant Holders. In the event that a bank or trust
company shall have been appointed as trustee for the holders of the Warrants
pursuant to subsection 4.2, such bank or trust company shall have all the powers
and duties of a warrant agent appointed pursuant to section 13 and shall accept,
in its own name for the account of the Company or such successor person as may
be entitled thereto, all amounts otherwise payable to the Company or such
successor, as the case may be, on exercise of this Warrant pursuant to this
section 1.

        2. Delivery of Stock Certificates, etc., on Exercise. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within 10 days thereafter, the Company at its expense (including the
payment by it of any applicable issue taxes) will cause to be issued in the name
of and delivered to the holder hereof, or as such holder (upon payment by such
holder of any applicable transfer taxes) may direct, a certificate or
certificates for the number of fully paid and nonassessable shares of Common
Stock (or Other Securities) to which such holder shall be entitled on such
exercise, plus, in lieu of any fractional share to which such holder would
otherwise be entitled, cash equal to such fraction multiplied by the then
current market value of one full share, together with any other stock or other
securities and property (including cash, where applicable) to which such holder
is entitled upon such exercise pursuant to section 1 or otherwise.

        3. Adjustment for Dividends in Other Stock, Property, etc.;
Reclassification, etc. In case at any time or from time to time, the holders of
Common Stock (or Other Securities) shall have received, or (on or after the
record date fixed for the determination of shareholders eligible to receive)
shall have become entitled to receive, without payment therefor,

                  (a) other or additional stock or other securities or property
(other than cash) by way of dividend, or

                  (b) any cash (excluding cash dividends payable solely out of
earnings or earned surplus of the Company), or

                  (c) other or additional stock or other securities or property
(including cash) by way of spin-off, split-up, reclassification,
recapitalization, combination of shares or similar corporate rearrangement,

other than additional shares of Common Stock (or Other Securities) issued as a
stock dividend or in a stock-split (adjustments in respect of which are provided
for in subsection 5.3), then and in each such case the holder of this Warrant,
on the exercise hereof as provided in section 1, shall be entitled to receive
the amount of stock and other securities and property (including cash in the
cases referred to in subdivisions (b) and (c) of this section 3) which such
holder would hold on the date of such exercise if on the date hereof he had been
the holder of record of the number of shares of Common Stock called for on the
face of this Warrant and had thereafter, during the period from the date hereof
to and including the date of such exercise, retained such shares and all such
other or additional stock and other securities and property (including cash in
the cases referred to in subdivisions (b) and (c) of this section 3) receivable
by him as aforesaid during such period, giving effect to all adjustments called
for during such period by sections 4, 5 or 6.


<PAGE>
                                       -4-


        4. Adjustment for Reorganization, Consolidation, Merger, etc.

           4.1 Reorganization, Consolidation, Merger, etc. In case at any time
or from time to time, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person, or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then, in each such
case, the holder of this Warrant, on the exercise hereof as provided in section
1 at any time after the consummation of such reorganization, consolidation or
merger o the effective date of such dissolution, as the case may be, shall
receive, in lieu of the Common Stock (or Other Securities) issuable on such
exercise prior to such consummation or such effective date, the stock and other
securities and property (including cash) to which such holder would have been
entitled upon such consummation or in connection with such dissolution, as the
case may be, if such holder had so exercised this Warrant, immediately prior
thereto, all subject to further adjustment as provided in section 3, 5 and 6.

           4.2 Dissolution. In the event of any dissolution of the Company
following the transfer of all or substantially all of its properties or assets,
the Company, prior to such dissolution, shall at its expense deliver or cause to
be delivered the stock and other securities and property (including cash, where
applicable) receivable by the holders of the Warrants after the effective date
of such dissolution pursuant to this section 4 to a bank or trust company having
its principal office in Boston, Massachusetts, as trustee for the holder or
holders of the Warrants.

           4.3 Continuation of Terms. Upon any reorganization, consolidation,
merger or transfer (any dissolution following any transfer) referred to in this
section 4, this Warrant shall continue in full force and effect and the terms
hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer, the person acquiring all or substantially all of the
properties or assets of the Company, whether or not such person shall have
expressly assumed the terms of this Warrant as provided in section 7.

        5. Adjustment for Issue or Sale of Common Stock at Less Than the
Purchase Price in Effect.

           5.1 General. Except as provided in subsection 5.2, if and whenever
the Company shall issue or sell, or is, in accordance with subparagraphs 5.1(a)
through 5.1(g), deemed to have issued or sold, any shares of Common Stock for a
consideration per share less than the Purchase Price in effect immediately prior
to the time of such issue or sale, then, forthwith upon such issue or sale, the
Purchase Price shall be reduced to the price at which the Company issued or
sold, or is deemed to have issued or sold, such shares of Common Stock.

        For purposes of this subsection 5.1, the following subsections 5.1(a)
through 5.1(g) shall also be applicable:


<PAGE>
                                       -5-


           (a) Issuance of Rights or Options. In case at any time the Company
shall in any manner grant (whether directly or by assumption in a merger or
otherwise) any warrants or other rights to subscribe for or to purchase, or any
options for the purchase of, Common Stock or any stock or security convertible
into or exchangeable for Common Stock (such warrants, rights or options being
called "Options" and such convertible or exchangeable stock or securities being
called "Convertible Securities") whether or not such Options or the right to
convert or exchange any such Convertible Securities are immediately exercisable,
and the price per share for which Common Stock is issuable upon the exercise of
such Options or upon the conversion or exchange of such Convertible Securities
(determined by dividing (i) the total amount, if any, received or receivable by
the Company as consideration for the granting of such Options, plus the minimum
aggregate amount of additional consideration payable to the Company upon the
exercise of all such Options, plus, in the case of such Options which relate to
Convertible Securities, the minimum aggregate amount of additional
consideration, if any, payable upon the issue or sale of such Convertible
Securities and upon the conversion or exchange thereof by, (ii) the total
maximum number of shares of Common Stock issuable upon the exercise of such
Options or upon the conversion or exchange of all such Convertible Securities
issuable upon the exercise of such Option) shall be less than the Purchase Price
in effect immediately prior to the time of the granting of such Options, then
the total maximum number of shares of Common Stock issuable upon the exercise of
such Options shall be deemed to have been issued for such price per share as of
the date of granting of such Options or the issuance of such Convertible
Securities and thereafter shall be deemed to be outstanding. Except as otherwise
provided in subsection 5.1(c), no adjustment of the Purchase Price shall be made
upon the actual issue of such Common Stock or of such Convertible Securities
upon exercise of such Options or upon the actual issue of such Common Stock upon
conversion or exchange of such Convertible Securities.

           (b) Issuance of Convertible Securities. In case the Company shall in
any manner issue (whether directly or by assumption in a merger or otherwise) or
sell any Convertible Securities, whether or not the rights to exchange or
convert any such Convertible Securities are immediately exercisable, and the
price per share for which Common Stock is issuable upon such conversion or
exchange (determined by dividing (i) the total amount received or receivable by
the Company as consideration for the issue or sale of such Convertible
Securities, plus the minimum aggregate amount of additional consideration, if
any, payable to the Company upon the conversion or exchange thereof, by (ii) the
total maximum number of shares of Common Stock issuable upon the conversion or
exchange of all such Convertible Securities) shall be less than the Purchase
Price in effect immediately prior to the time of such issue or sale, then the
total maximum number of shares of Common Stock issuable upon conversion or
exchange of all such Convertible Securities shall be deemed to have been issued
for such price per share as of the date of the issue or sale of such Convertible
Securities and thereafter shall be deemed to be outstanding, provided that (a)
except as otherwise provided in subsection 5.1(c), no adjustment of the Purchase
Price shall be made upon the actual issue of such Common Stock upon conversion
or exchange of such Convertible Securities and (b) if any such issue or sale of
such Convertible Securities is made upon exercise of any Options to purchase any
such Convertible Securities for which adjustments of the Purchase Price have
been or are to be made


<PAGE>
                                       -6-


pursuant to other provisions of this subsection 5.1, no further adjustment of
the Purchase Price shall be made by reason of such issue or sale.

           (c) Change in Option Price or Conversion Rate. Upon the happening of
any of the following events, namely, if the purchase price provided for in any
Option referred to in subsection 5.1(a), the additional consideration, if any,
payable upon the conversion or exchange of any Convertible Securities referred
to in subsection 5.1(a) or 5.1(b), or the rate at which Convertible Securities
referred to in subsection 5.1(a) or 5.1(b) are convertible into or exchangeable
for Common Stock shall change at any time (including, but not limited to,
changes under or by reason of provisions designed to protect against dilution),
the Purchase Price in effect at the time of such event shall forthwith be
readjusted to the Purchase Price which would have been in effect at such time
had such Options or Convertible Securities still outstanding provided for such
changed purchase price, additional consideration or conversion rate, as the case
may be, at the time initially granted, issued or sold, but only if as a result
of such adjustment the Purchase Price then in effect hereunder is thereby
reduced; and on the expiration of any such Option or the termination of any such
right to convert or exchange such Convertible Securities, the Purchase Price
then in effect hereunder shall forthwith be increased to the Purchase Price
which would have been in effect at the time of such expiration or termination
had such Option or Convertible Securities, to the extent outstanding immediately
prior to such expiration or termination, never been issued.

           (d) Stock Dividends. In case the Company shall declare a dividend or
make nay other distribution upon any stock of the Company payable in Common
Stock (except for dividends or distributions upon the Common Stock), Options or
Convertible Securities, any Common Stock, Options or Convertible Securities, as
the case may be, issuable in payment of such dividend or distribution shall be
deemed to have been issued or sold without consideration.

           (e) Consideration for Stock. In case any shares of Common Stock,
Options or Convertible Securities shall be issued or sold for cash, the
consideration received therefor shall be deeded to be the amount received by the
Company therefor, without deduction therefrom of any expenses incurred or any
underwriting commissions or concessions paid or allowed by the Company in
connection therewith. In case any shares of Common Stock, Options or Convertible
Securities shall be issued or sold for a consideration other than cash, the
amount of the consideration other than cash received by the Company shall be
deemed to be the fair value of such consideration as determined in good faith by
the Board of Directors of the Company, without deduction of any expenses
incurred or any underwriting commissions or concessions paid or allowed by the
Company in connection therewith. In case any Options shall be issued in
connection with the issue and sale of other securities of the Company, together
comprising one integral transaction in which no specific consideration is
allocated to such Options by the parties thereto, such Options shall be deemed
to have been issued for such consideration as determined in good faith by the
Board of Directors of the Company.

           (f) Record Date. In case the Company shall take a record of the
holders of its Common Stock for the purpose of entitling them (i) to receive a
dividend or other distribution payable in Common Stock, Options or Convertible
Securities or (ii) to subscribe for or purchase


<PAGE>
                                       -7-


Common Stock, Options or Convertible Securities, then such record date shall be
deemed to be the date of the issue or sale of the shares of Common Stock deemed
to have been issued or sold upon the declaration of such dividend or the making
of such other distribution or the date of the granting of such right of
subscription or purchase, as the case may be.

           (g) Treasury Shares. The disposition of any shares of Common Stock
owned or held by or for the account of the Company shall be considered an issue
or sale of Common Stock for the purpose of this subsection 5.1(g).

         5.2 Certain Issues of Common Stock Excepted. Anything herein to the
contrary notwithstanding, the Company shall not be required to make any
adjustment of the Purchase Price in the case of the issuance of up to an
aggregate of 500,000 shares (appropriately adjusted to reflect the occurrence of
any event described in subsection 5.3) of Common Stock to directors, officers or
employees of the Company in connection with their service as directors of the
Company or their employment by the Company.

         5.3 Extraordinary Events. In the event that the Company shall (i) issue
additional shares of the Common Stock as a dividend or other distribution on
outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock,
or (iii) combine its outstanding shares of the Common Stock into a smaller
number of shares of the Common Stock, then, in each such event, the Purchase
Price shall, simultaneously with the happening of such event, be adjusted by
multiplying the then Purchase Price by a fraction, the numerator of which shall
be the number of shares of Common Stock outstanding immediately prior to such
event and the denominator of which shall be the number of shares of Common Stock
outstanding immediately after such event, and the product so obtained shall
thereafter be the Purchase Price then in effect. The Purchase Price, as so
adjusted, shall be readjusted in the same manner upon the happening of any
successive event of events described herein in this subsection 5.3. The holder
of this Warrant shall thereafter, on the exercise hereof as provided in section
1, be entitled to receive that number of shares of Common Stock determined by
multiplying the number of shares of Common Stock which would otherwise (but for
the provisions of this subsection 5.3) be issuable on such exercise by a
fraction of which (i) the numerator is the Purchase Price which would otherwise
(but for the provisions of this subsection 5.3) be in effect, and (ii) the
denominator is the Purchase Price in effect on the date of such exercise.

         6. Adjustment for Net Income or Public Offering.

           6.1 Net Income. Upon the public release of the Company's audited
financial statements for its fiscal year ending December 31, 1991, the number of
shares of Common Stock for which this Warrant is then exercisable shall be
reduced by 8,000 shares of Common Stock for each $100,000 of annual net income
in excess of $1,500,000, based on reported earnings, as if fully taxed,
calculated on an unconsolidated basis which excludes only the financial results
of any majority-owned subsidiaries operating outside of the New York
metropolitan area.

           6.2 Public Offering. In case at any time prior to December 31, 1991
the Company shall effect a firm commitment underwritten public offering of
shares of Common 


<PAGE>
                                       -8-


Stock in which (i) the aggregate price paid for such shares by the public shall
be at least $5,000,000, (ii) the price paid by the public for such shares shall
be at least $10 per share (approximately adjusted to reflect the occurrence of
any event described in section 4) and (iii) the holders of the Warrants are
permitted by the managing underwriter for the offering to include all the shares
of Common Stock then held by them in the offering, then the number of shares of
Common Stock for which this Warrant is exercisable shall be reduced by fifty
(50%) percent.

         7. No Dilution or Impairment. The Company will not, by amendment of its
Restated Certificate of Incorporation or through any reorganization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms of the Warrants, but will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such action as may
be necessary or appropriate in order to protect the rights of the holders of the
Warrants against dilution or other impairment. Without limiting the generality
of the foregoing, the Company (a) will not increase the par value of any shares
of stock receivable on the exercise of the Warrants above the amount payable
therefor on such exercise, (b) will take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of stock on the exercise of all Warrants from time to
time outstanding, (c) will not issue any capital stock of any class which is
preferred as to dividends or as to the distribution of assets upon voluntary or
involuntary dissolution, liquidation or winding up, unless the rights of the
holders thereof shall be limited to a fixed sum or percentage of par value in
respect of participation in dividends and in any such distribution of assets,
and (d) will not transfer all or substantially all of its properties and assets
to any other person (corporate or otherwise), or consolidate with or merge into
any other person or permit any such person to consolidate with or merge into the
Company (if the Company is not the surviving person), unless such other person
shall expressly assume in writing and will be bound by all the terms of the
Warrants.

         8. Accountants' Certificate as to Adjustments. In each case of any
adjustment or readjustment in the shares of Common Stock (or Other Securities)
issuable on the exercise of the Warrants, the Company at its expense will
promptly cause independent certified public accountants of recognized standing
selected by the Company to compute such adjustment or readjustment in accordance
with the terms of the Warrants and prepare a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based, including a statement of (a) the
consideration received or receivable by the Company for any additional shares of
Common Stock (or Other Securities) issued or sold or deemed to have been issued
or sold, (b) the number of shares of Common Stock (or Other Securities)
outstanding or deemed to be outstanding, and (c) the Purchase Price and the
number of shares of Common Stock to be received upon exercise of this Warrant,
in effect immediately prior to such issue or sale and as adjusted and readjusted
and provided in this Warrant. The Company will forthwith mail a copy of each
such certificate to each holder of a Warrant, and will, on the written request
at any time of any holder of a Warrant, furnish to such holder a like
certificate setting forth the Purchase Price at the time in effect and showing
how it was calculated.


<PAGE>
                                       -9-


         9. Notices of Record Date, etc. In the event of

            (a) any taking by the Company of a record of the holders of any
class or securities for the purpose of determining the holders thereof who are
entitled to receive any dividend or other distribution, or any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, or

            (b) any capital reorganization of the Company, any reclassification
or recapitalization of the capital stock of the Company or any transfer of all
or substantially all the assets of the Company to or consolidation or merger of
the Company with or into any other person, or

            (c) any voluntary or involuntary dissolution, liquidation or
winding-up of the Company, or

            (d) any proposed issue or grant by the Company of any shares of
stock of any class or any other securities, or any right or option to subscribe
for, purchase or otherwise acquire any shares of stock of any class or any other
securities (other than the issue of Common Stock on the exercise of the
Warrants),

then and in each such event the Company will mail or cause to be mailed to each
holder of a Warrant a notice specifying (i) the date on which any such record is
to be taken for the purpose of such dividend, distribution or right, and stating
the amount and character of such dividend, distribution or right, (ii) the date
on which any such reorganization, reclassification, recapitalization, transfer,
consolidation, merger, dissolution, liquidation or winding-up is to take place,
and the time, if any is to be fixed, as of which the holders of record of Common
Stock (or Other Securities) shall be entitled to exchange their shares of Common
Stock (or Other Securities) for securities or other property deliverable on such
reorganization, reclassification, recapitalization, transfer, consolidation,
merger, dissolution, liquidation or winding-up, and (iii) the amount and
character of any stock or other securities, or rights or options with respect
thereto, proposed to be issued or granted, the date of such proposed issue or
grant is to be offered or made. Such notice shall be mailed at least 20 days
prior to the date specified in such notice on which any such action is to be
taken.

         10. Reservation of Stock, etc., Issuable on Exercise of Warrants. The
Company will at all times reserve and keep available, solely for issuance and
delivery on the exercise of the Warrants, all shares of Common Stock (or Other
Securities) from time to time issuable on the exercise of the Warrants.

         11. Exchange of Warrants. On surrender of any Warrant, properly
endorsed, to the Company, the Company at its expense will issue and deliver to
or on the order of the holder thereof a new Warrant or Warrants of like tenor,
in the name of such holder or as such holder (on payment by such holder of any
applicable transfer taxes) may direct, calling in the aggregate on the face or
faces thereof for the number of shares of Common Stock called for on the face or
faces of the Warrant or Warrants so surrendered.


<PAGE>
                                      -10-


         12. Replacement of Warrants. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of any
Warrant and, in the case of any such loss, theft or destruction of any Warrant,
on delivery of an indemnity agreement or security reasonably satisfactory in
form and amount to the Company or, in the case of any such mutilation, on
surrender and cancellation of such Warrant, the Company at its expense will
execute and deliver, in lieu thereof, a new Warrant of like tenor.

         13. Warrant Agent. The Company may, by written notice to each holder of
a Warrant, appoint an agent having an office in either Boston, Massachusetts or
New York, New York for the purpose of issuing Common Stock (or Other Securities)
on the exercise of the Warrants pursuant to section 1, exchanging Warrants
pursuant to section 11, and replacing Warrants pursuant to section 12, or any of
the foregoing, and thereafter any such issuance, exchange or replacement, as the
case may be, shall be made at such office by such agent.

         14. Remedies. The Company stipulates that the remedies at law of the
holder of this Warrant in the event of any default or threatened default by the
Company in the performance of or compliance with any of the terms of this
Warrant are not and will not be adequate, and that such terms may be
specifically enforced by a decree for the specific performance of any agreement
contained herein or by an injunction against a violation of any of the terms
hereof or otherwise.

         15. Negotiability, etc. This Warrant is issued upon the following
terms, to all of which each holder or owner hereof by the taking hereof consents
and agrees:

             (a) title to this Warrant may be transferred by endorsement (by the
holder hereof executing the form of assignment at the end hereof) and delivery
in the same manner as in the case of a negotiable instrument transferable by
endorsement and delivery;

             (b) any person in possession of this Warrant properly endorsed is

                A. Preferred Stock. The Preferred Stock may be issued from time
to time in one or more series and with such designation for each such series as
shall be stated and expressed in the resolution or resolutions providing for the
issue of each such series adopted by the Board of Directors. The Board of
Directors in any such resolution or resolutions is expressly authorized to state
and express for each such series:

                   (i) Voting rights, if any, including without limitation the
authority to confer multiple votes per share, voting rights as to specified
matters or issues such as mergers, consolidations or sales of assets, or voting
rights to be exercised either together with holders of Common Stock as a single
class, or independently as a separate class;

which the holders of stock of such series shall be entitled to receive
dividends, and whether such dividends shall be cumulative or non-cumulative and
if cumulative the terms upon which such dividends shall be cumulative;

                   (iii) The price or prices and the time or times at and the
manner in which the stock of such series shall be redeemable;

                   (iv) The rights to which the holders of the shares of stock

dissolution or winding up of the Corporation; 


<PAGE>
                                       -4-


                   (v) The terms, if any, upon which the shares of stock of such
series shall be convertible into, or exchangeable for, shares of stock of any
other class of classes or of any other series of the same or any other class or
classes, including the price or prices or the rate or rates of conversion or
exchange and the terms of adjustment, if any; and

                   (vi) Any other designations, preferences and relative,
participating, optional or other special rights, and qualifications, limitations
or restrictions thereof so far as they are not inconsistent with the provisions
of the Certificate of Incorporation, as amended, and to the full extent now or
hereafter permitted by the laws of the State of New York.

         All shares of the Preferred Stock of any one series shall be identical
to each other in all aspects, except that shares of any one series issued at
different times may differ as to the dates from which dividends thereon, if
cumulative, shall be cumulative.

                B. Common Stock.

                   (i) Whenever dividends upon the Preferred Stock at the time
outstanding shall have been paid in full for all past dividend periods or
declared and set apart for payment, such dividends as may be determined by the
Board of Directors may be declared by the Board of Directors and paid from time
to time to the holders of the Common Stock, subject to any restrictions stated
and expressed in any resolution or resolutions adopted by the Board of Directors
including any resolutions providing for the issuance of Preferred Stock.

                   (ii) In the event of any liquidation, dissolution or winding
up of the affairs of the Corporation, whether voluntary or involuntary, all

time outstanding of the full amounts to which they shall be entitled, shall be
divided and distributed among the holders of Common Stock according to their
respective shares.


<PAGE>
                                       -5-


                   (iii) Each holder of the Common Stock shall have one vote in
respect of each share of such stock held by him.

                C. Pre-emptive Rights. No shareholder of this corporation shall
have a pre-emptive right because of his shareholdings to have first offered to
him any part of any of the presently authorized shares of this corporation
hereafter issued, optioned, or sold, or any part of any debenture, bonds, notes,
or securities of this corporation convertible into shares hereafter issued,
optioned, or sold by the corporation. This provision shall operate to defeat
rights in all shares and classes of shares now authorized and in all debentures,
bonds, notes, or securities of the corporation which may be convertible into
shares, and also to defeat pre-emptive rights in any and all shares and classes
of shares and securities convertible into shares which this corporation may be
hereafter authorized to issue by any amended certificate duly filed. Thus, any
and all of the shares of this corporation presently authorized, and any and all
debentures, bonds, notes, or securities of this corporation convertible into
shares and any and all of the shares of this corporation which may hereafter be
authorized, may at any time be issued, optioned, and contracted for sale, and/or
sold and disposed of by direction of the Board of Directors of this corporation
to such persons, and upon such terms and conditions as may to the Board of
Directors seem proper and advisable, without first offering the said shares or
securities or any part thereof to existing shareholders.

                D. Stock Rights and Options. The corporation shall have the
power to create and issue rights, warrants, or options entitling the holders
thereof to purchase from the corporation any shares of its capital stock of any
class or classes, upon such terms and conditions and at such time and prices as
the Board of Directors may provide, which terms and conditions shall be
incorporated in an instrument or instruments evidencing such rights. In the
absence of 


<PAGE>
                                       -6-


fraud, the judgment of the Directors as to the adequacy of consideration for the
issuance of such rights or options and the sufficiency thereof shall be
conclusive.

         FIFTH: The Secretary of Sate is designated as the agent of the
corporation upon whom process against it may be served, and the post office
address to which the Secretary of State shall mail a copy of such process served
upon him is "c/o Murtagh, Cohen & Byrne, 1122 Franklin Avenue, Garden City, New
York 11530."

         5. The Restatement of the Certificate of Incorporation was authorized
by the vote of the Board, followed by the affirmative vote of the holders of a
majority of all outstanding shares entitled to vote thereon at a meeting of
shareholders.

         IN WITNESS WHEREOF, we have signed this Restated Certificate of
Incorporation on the 22nd day of May, 1989.

                                                                       EXHIBIT D

                      SERIES A CONVERTIBLE PREFERRED STOCK


         1. Number of Shares. The series of Preferred Stock designated and known
as "Series A Convertible Preferred Stock" shall consist of no more than
1,000,000 shares.

         2. Voting.

            2A. General. Except as may be otherwise provided in these terms of
the Series A Convertible Preferred Stock or by law, the Series A Convertible
Preferred Stock shall vote together with all other classes and series of stock
of the Corporation as a single class on all actions to be taken by the
stockholders of the Corporation. Each share of Series A Convertible Preferred
Stock shall entitle the holder thereof to such number of votes per share on each
such action as shall equal the number of shares of Common Stock (including
fractions of a share) into which each share of Series A Convertible Preferred
Stock is then convertible.

            2B. Board Size. The Corporation shall not, without the written
consent or affirmative vote of the holders of at least two-thirds of the then
outstanding shares of Series A Convertible Preferred Stock, given in writing or
by vote at a meeting, consenting or voting (as the case may be) separately as a
series, increase the maximum number of directors constituting the Board of
Directors to a number in excess of eleven (11).

            2C. Board Seats. The holders of the Series A Convertible Preferred
Stock, voting as a separate series, shall be entitled to elect one (1) director
of the Corporation. The holders of the Common Stock, voting as a separate class,
shall be entitled to elect the remaining directors of the Corporation.
Notwithstanding the foregoing or anything else to the contrary provided in the
Restated Certificate of Incorporation, if the Corporation fails or refuses, for
any reason or for no reason, to redeem on the Redemption Date (as defined in
paragraph 7) all of the then outstanding shares of Series A Convertible
Preferred Stock in accordance with the terms and provisions of paragraph 7, the
holders of the Series A Convertible Preferred Stock, voting as a separate
series, shall be entitled to elect a majority of the directors of the
Corporation. At any meeting (or in a written consent in lieu thereof) held for
the purpose of electing directors, the presence in person or by proxy (or the
written consent) of the holders of a majority of the shares of Series A
Convertible Preferred Stock then outstanding shall constitute a quorum of the
Series A Convertible Preferred Stock for the election of directors to be elected
solely by the holders of the Series A Convertible Preferred Stock or jointly by
the holders of the Series A Convertible Preferred Stock and the Common Stock. A
vacancy in any directorship elected by the holders of the Series A Convertible
Preferred Stock shall be filled only by vote or written consent of the holders
of the Series A Convertible Preferred Stock.

         3. Dividends. The holders of the Series A Convertible Preferred Stock
shall be entitled to receive, out of funds legally available therefor, when and
if declared by the Board of Directors, quarterly dividends at the rate per annum
of $.30 per share (the "Accruing 


<PAGE>
                                       -2-


Dividends"). Accruing Dividends shall accrue from day to day, whether or not
earned or declared, and shall be cumulative from the date of issuance of the
Series A Convertible Preferred Stock.

         4. Liquidation. Upon any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, the holders of the shares of
Series A Convertible Preferred Stock shall first be entitled, before any
distribution or payment is made upon any stock ranking on liquidation junior to
the Series A Convertible Preferred Stock, to be paid an amount equal to $3.00
per share plus, in the case of each share, an amount equal to all Accruing
Dividends unpaid thereon (whether or not declared) and any other dividends
declared but unpaid thereon, computed to the date payment thereof is made
available, such amount payable with respect to one share of Series A Convertible
Preferred Stock being sometimes referred to as the "Liquidation Preference
Payment" and with respect to all shares of Series A Convertible Preferred Stock
being sometimes referred to as the "Liquidation Preference Payment" and with
respect to all shares of Series A Convertible Preferred Stock being sometimes
referred to as the "Liquidation Preference Payments". If upon such liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
the assets to be distributed among the holders of Series A Convertible Preferred
Stock shall be insufficient to permit payment in full to the holders of Series A
Convertible Preferred Stock of the Liquidation Preference Payments, then the
entire assets of the Corporation to be so distributed shall be distributed
ratably among the holders of Series A Convertible Preferred Stock. Upon any such
liquidation, dissolution or winding up of the Corporation, immediately after the
holders of Series A Convertible Preferred Stock shall have been paid in full the
Liquidation Preference Payments, the remaining net assets of the Corporation
available for distribution shall be distributed ratably among the holders of
Series A Convertible Preferred Stock and Common Stock (with each share of Series
A Convertible Preferred Stock being deemed, for such purpose, to be equal to the
number of shares of Common Stock (including fractions of a share) into which
such share of Series A Convertible Preferred Stock is convertible immediately
prior to the close of business on the business day fixed for such distribution).
Written notice of such liquidation, dissolution or winding up, stating a payment
date and the place where said payments shall be made, shall be given by mail,
postage prepaid, or by telex to non-U.S. residents, not less than 20 days prior
to the payment date stated therein, to the holders of record of Series A
Convertible Preferred Stock, such notice to be addressed to each such holder at
its address as shown by the records of the Corporation. The consolidation or
merger of the Corporation into or with any other entity or entities which
results in the exchange of outstanding shares of the Corporation for securities
or other consideration issued or paid or caused to be issued or paid by any such
entity or affiliate thereof, and the sale or transfer by the Corporation of all
or substantially all its assets, shall be deemed to be a liquidation,
dissolution or winding up of the Corporation within the meaning of the
provisions of this paragraph 4. For purposes hereof, the Common Stock shall rank
on liquidation junior to the Series A Convertible Preferred Stock.

         5. Restrictions. At any time when shares of Series A Convertible
Preferred Stock are outstanding, except where the vote or written consent of the
holders of a greater number of shares of the Corporation is required by law or
by the Restated Certificate of Incorporation, and in addition to any other vote
required by law or the Restated Certificate of Incorporation, without 


<PAGE>
                                       -3-


the approval of the holders of at least two-thirds of the then outstanding
shares of Series A Convertible Preferred Stock, given in writing or by vote at a
meeting, consenting or voting (as the case may be) separately as a series, the
Corporation will not:

            5A. Create or authorize the creation of any additional class or
series of shares of stock unless the same ranks junior to the Series A
Convertible Preferred Stock as to the distribution of assets on the liquidation,
dissolution or winding up of the Corporation, or increase the authorized amount
of the Series A Convertible Preferred Stock or increase the authorized amount of
any additional class or series of shares of stock unless the same ranks junior
to the Series A Convertible Preferred Stock as to the distribution of assets on
the liquidation, dissolution or winding up of the Corporation, or create or
authorize any obligation or security convertible into shares of Series A
Convertible Preferred Stock or into shares of any other class or series of stock
unless the same ranks junior to the Series A Convertible Preferred Stock as to
the distribution of assets on the liquidation, dissolution or winding up of the
Corporation, whether any such reaction, authorization or increase shall be by
means of amendment to the Restated Certificate of Incorporation or by merger,
consolidation or otherwise;

            5B. Consent to any liquidation, dissolution or winding up of the
Corporation or consolidate or merge into or with any other entity or entities or
sell or transfer all or substantially all its assets;

            5C. Amend, alter or repeal its Restated Certificate of Incorporation
or By-laws in a manner which adversely affects the holders of Series A
Convertible Preferred Stock;

            5D. Purchase or set aside any sums for the purchase of, or pay any
dividend or make any distribution on, any shares of stock other than the Series
A Convertible Preferred Stock, except for dividends or other distributions
payable on the Common Stock solely in the form of additional shares of Common
Stock and except for the purchase of shares of Common Stock from former
employees of the Corporation who acquired such shares directly from the
Corporation, if each such purchase is made pursuant to contractual rights held
by the Corporation relating to the termination of employment of such former
employee and the purchase price does not exceed the original issue price paid by
such former employee to the Corporation for such shares; or

            5E. Redeem or otherwise acquire any shares of Series A Convertible
Preferred Stock except as expressly authorized in paragraph 7 hereof or pursuant
to a purchase offer made pro rata to all holders of the shares of Series A
Convertible Preferred Stock on the basis of the aggregate number of outstanding
shares of Series A Convertible Preferred Stock then held by each such holder.

         6. Conversions. The holders of shares of Series A Convertible Preferred
Stock shall have the following conversion rights:

            6A. Right to Convert. Subject to the terms and conditions of this
paragraph 6, the holder of any share or shares of Series A Convertible Preferred
Stock shall have the right, at 


<PAGE>
                                       -4-


its option at any time, to convert any such shares of Series A Convertible
Preferred Stock (except that upon any liquidation of the Corporation the right
of conversion shall terminate at the close of business on the business day fixed
for payment of the amount distributable on the Series A Convertible Preferred
Stock) into such number of fully paid and nonassessable shares of Common Stock
as is obtained by (i) multiplying the number of shares of Series A Convertible
Preferred Stock so to be converted by $3.00 and (ii) dividing the result by the
conversion price of $3.00 per share or, in case an adjustment of such price has
taken place pursuant to the further provisions of this paragraph 6, then by the
conversion price as last adjusted and in effect at the date any share or shares
of Series A Convertible Preferred Stock are surrendered for conversion (such
price, or such price as last adjusted, being referred to as the "Conversion
Price"). Such rights of conversion shall be exercised by the holder thereof by
giving written notice that the holder elects to convert a stated number of
shares of Series A Convertible Preferred Stock into Common Stock and by
surrender of a certificate or certificates for the shares so to be converted to
the Corporation at its principal office (or such other office or agency of the
Corporation as the Corporation may designate by notice in writing to the holders
of the Series A Convertible Preferred Stock) at any time during its usual
business hours on the date set forth in such notice, together with a statement
of the name or names (with address) in which the certificate or certificates for
shares of Common Stock shall be issued.

            6B. Issuance of Certificates: Time Conversion Effected. Promptly
after the receipt of the written notice referred to in subparagraph 6A and
surrender of the certificate or certificates for the share or shares of Series A
Convertible Preferred Stock to be converted, the Corporation shall issue and
deliver, or cause to be issued and delivered, to the holder, registered in such
name or names as such holder may direct, a certificate or certificates for the
number of whole shares of Common stock issuable upon the conversion of such
share or shares of Series A Convertible Preferred Stock. To the extent permitted
by law, such conversion shall be deemed to have been effected and the Conversion
Price shall be determined as of the close of business on the date on which such
written notice shall have been received by the Corporation and the certificate
or certificates for such share or shares shall have been surrendered as
aforesaid, and at such time the rights of the holder of such share or shares of
Series A Convertible Preferred Stock shall cease, and the person or persons in
whose name or names any certificate or certificates for shares of Common Stock
shall be issuable upon such conversion shall be deemed to have become the holder
or holders of record of the shares represented thereby.

            6C. Fractional Shares; Dividends; Partial Conversion. No fractional
shares shall be issued upon conversion of Series A Convertible Preferred Stock
into Common Stock and no payment of adjustment shall be made upon any conversion
on account of any cash dividends on the Common Stock issued upon such
conversion. At the time of each conversion, the Corporation shall pay in cash an
amount equal to all dividends, excluding Accruing Dividends, accrued and unpaid
on the shares of Series A Convertible Preferred Stock surrendered for conversion
to the date upon which such conversion is deemed to take place as provided in
subparagraph 6B. In case the number of 


<PAGE>
                                       -5-


shares of Series A Convertible Preferred Stock represented by the certificate or
certificates surrendered pursuant to subparagraph 6A exceeds the number of
shares converted, the Corporation shall, upon such conversion, execute and
deliver to the holder, at the expense of the Corporation, a new certificate of
certificates for the number of shares of Series A Convertible Preferred Stock
represented by the certificate or certificates surrendered which are not to be
converted. If any fractional share of Common Stock would, except for the
provisions of the first sentence of this subparagraph 6C, be delivered upon such
conversion, the Corporation, in lieu of delivering such fractional share, shall
pay to the holder surrendering the Series A Convertible Preferred Stock for
conversion an amount in cash equal to the current market price of such
fractional share as determined in good faith by the Board of Directors of the
Corporation.

            6D. Adjustment of Price Upon Issuance of Common Stock. Except as
provided in subparagraph 6E, if and whenever the Corporation shall issue or
sell, or is, in accordance with subparagraphs 6D(1) through 6D(7), deemed to
have issued or sold, any shares of Common Stock for a consideration per share
less than the Conversion Price in effect immediately prior to the time of such
issue or sale, then, forthwith upon such issue or sale, the Conversion Price
shall be reduced to the price at which the Corporation issued or sold, or is
deemed to have issued or sold, such shares of Common Stock.

         For purposes of this subparagraph 6D, the following subparagraphs 6D(1)
to 6D(7) shall also be applicable:

                6D(1) Issuance of Rights or Options. In case at any time the
         Corporation shall in any manner grant (whether directly or by
         assumption in a merger or otherwise) any warrants or other rights to
         subscribe for or to purchase, or any options for the purchase of,
         Common Stock or any stock or security convertible into or exchangeable
         for Common Stock (such warrants, rights or options being called
         "Options" and such convertible or exchangeable stock or securities
         being called "Convertible Securities") whether or not such Options or
         the right to convert or exchange any such Convertible Securities are
         immediately exercisable, and the price per share for which Common Stock
         is issuable upon the exercise of such Options or upon the conversion or
         exchange of such Convertible Securities (determined by dividing (1) the
         total amount, if any, received or receivable by the Corporation as
         consideration for the granting of such Options, plus the minimum
         aggregate amount of additional consideration payable to the Corporation
         upon the exercise of all such Options, plus, in the case of such
         Options which relate to Convertible Securities, the minimum aggregate
         amount of additional consideration, if any, payable upon the issue or
         sale of such Convertible Securities and upon the conversion or exchange
         thereof, by (ii) the total maximum number of shares of Common Stock
         issuable upon the exercise of such Options or upon the conversion or
         exchange of all such Convertible Securities issuable upon the exercise
         of such Options) shall be less than the Conversion Price in effect
         immediately prior to the time of the granting of such Options, then the
         total maximum number of shares of Common Stock issuable upon the
         exercise of such Options or upon conversion or exchange of the total
         maximum amount of such Convertible Securities issuable upon the
         exercise of such Options shall be deemed to have been issued for such
         price per share as of the date of granting of such Options or the
         issuance of such Convertible Securities and thereafter shall be deemed
         to be outstanding. Except as otherwise provided in subparagraph 6D(3),
         no adjustment of the Conversion Price shall be made upon the actual
         issue of such Common Stock or of

                                       -6-


         such Convertible Securities upon exercise of such Options or upon the
         actual issue of such Common Stock upon conversion or exchange of such
         Convertible Securities.

                6D(2) Issuance of Convertible Securities. In case the
         Corporation shall in any manner issue (whether directly or by
         assumption in a merger or otherwise) or sell any Convertible
         Securities, whether or not the rights to exchange or convert any such
         Convertible Securities are immediately exercisable, and the price per
         share for which Common Stock is issuable upon such conversion or
         exchange (determined by dividing (i) the total amount received or
         receivable by the Corporation as consideration for the issue or sale of
         such Convertible Securities, plus the minimum aggregate amount of
         additional consideration, if any, payable to the Corporation upon the
         conversion or exchange thereof, by (ii) the total maximum number of
         shares of Common Stock issuable upon the conversion or exchange of all
         such Convertible Securities) shall be less than the Conversion Price in
         effect immediately prior to the time of such issue or sale, then the
         total maximum number of shares of Common Stock issuable upon conversion
         or exchange of all such Convertible Securities shall be deemed to have
         been issued for such price per share as of the date of the issue or
         sale of such Convertible Securities and thereafter shall be deemed to
         be outstanding, provided that (a) except as otherwise provided in
         subparagraph 6D(3), no adjustment of the Conversion Price shall be made
         upon the actual issue of such Common Stock upon conversion or exchange
         of such Convertible Securities and (b) if any such issue or sale of
         such Convertible Securities is made upon exercise of any Options to
         purchase any such Convertible Securities for which adjustments of the
         Conversion Price have been or are to be made pursuant to other
         provisions of this subparagraph 6D, no further adjustment of the
         Conversion Price shall be made by reason of such issue or sale.

                6D(3) Change in Option Price or Conversion Rate. Upon the
         happening of any of the following events, namely, if the purchase price
         provided for in any Option referred to in subparagraph 6D(1), the
         additional consideration, if any, payable upon the conversion or
         exchange of any Convertible Securities referred to in subparagraph
         6D(1) or 6D(2), or the rate at which Convertible Securities referred to
         in subparagraph 6D(1) or 6D(2) are convertible into or exchangeable for
         Common Stock shall change at any time (including, but not limited to,
         changes under or by reason of provisions designed to protect against
         dilution), the Conversion Price in effect at the time of such event
         shall forthwith be readjusted to the Conversion Price which would have
         been in effect at such time had such Options or Convertible Securities
         still outstanding provided for such changed purchase price, additional
         consideration or conversion rate, as the case may be, at the time
         initially granted, issued or sold, but only if as a result of such
         adjustment the Conversion Price then in effect hereunder is thereby
         reduced; and on the expiration of any such Option or the termination of
         any such right to convert or exchange such Convertible Securities, the
         Conversion Price then in effect hereunder shall forthwith be increased
         to the Conversion Price which would have been in effect at the time of
         such expiration or termination had such Option or Convertible
         Securities, to the extent outstanding immediately prior to such
         expiration or termination, never been issued.

                6D(4) Stock Dividends. In case the Corporation shall declare a
         dividend or make any other distribution upon any stock of the
         Corporation payable in Common Stock (except for dividends or
         distributions upon the Common Stock), Options or Convertible
         Securities, any Common Stock, Options or Convertible Securities, as the
         case may be, issuable in payment of such dividend or distribution shall
         be deemed to have been issued or sold without consideration.

                6D(5) Consideration for Stock. In case any shares of Common
         Stock, Options or Convertible Securities shall be issued or sold for
         cash, the consideration received therefor shall be deemed to be the
         amount received by the Corporation therefor, without deduction
         therefrom of any expenses incurred or any underwriting commissions or
         concessions paid or allowed by the Corporation in connection therewith.
         In case any shares of Common Stock, Options or Convertible Securities
         shall be issued or sold for a consideration other than cash, the amount
         of the consideration other than cash received by the Corporation shall
         be deemed to be the fair value of such consideration as determined in
         good faith by the Board of Directors of the Corporation, without
         deduction of any expenses incurred or any underwriting commissions or
         concessions paid or allowed by the Corporation in connection therewith.
         In case any Options shall be issued in connection with the issue and
         sale of other securities of the Corporation, together comprising one
         integral transaction in which no specific consideration is allocated to
         such Options by the parties thereto, such Options shall be deemed to
         have been issued for such consideration as determined in good faith by
         the Board of Directors of the Corporation.

                6D(6) Record Date. In case the Corporation shall take a record
         of the holders of its Common Stock for the purpose of entitling them
         (i) to receive a dividend or other distribution payable in Common
         Stock, Options or Convertible Securities or (ii) to subscribe for or
         purchase Common Stock Options or Convertible Securities, then such
         record date shall be deemed to be the date of the issue or sale of the
         shares of Common Stock deemed to have been issued or sold upon the
         declaration of such dividend or the making of such other distribution
         or the date of the granting of such right of subscription or purchase,
         as the case may be.

                6D(7) Treasury Shares. The disposition of any shares of Common
         Stock owned or held by or for the account of the Corporation shall be
         considered an issue or sale of Common Stock for the purpose of this
         subparagraph 6D.

            6E. Certain Issues of Common Stock Excepted. Anything herein to the
contrary notwithstanding, the Corporation shall not be required to make any
adjustment of the Conversion Price in the case of the issuance of up to an
aggregate of 500,000 shares (appropriately adjusted to reflect the occurrence of
any event described in subparagraph 6F) of Common Stock to directors, officers
or employees of the Corporation in connection with their service as directors of
the Corporation or their employment by the Corporation.

            6F. Subdivision of Combination of Common Stock. In case the
Corporation shall at any time subdivide (by any stock split, stock dividend or
otherwise) its outstanding


<PAGE>
                                       -8-


shares of Common Stock into a greater number of shares, the Conversion Price in
effect immediately prior to such subdivision shall be proportionately reduced
and, conversely, in case the outstanding shares of Common Stock shall be
combined into a smaller number of shares, the Conversion Price in effect
immediately prior to such combination shall be proportionately increased.

            6G. Reorganization or Reclassification. If any capital
reorganization or reclassification of the capital stock of the Corporation shall
be effected in such a way that holders of Common Stock shall be entitled to
receive stock, securities or assets with respect to or in exchange for Common
Stock, then, as a condition of such reorganization or reclassification, lawful
and adequate provisions shall be made whereby each holder of a share or shares
of Series A Convertible Preferred Stock shall thereupon have the right to
receive, upon the basis and upon the terms and conditions specified herein and
in lieu of the shares of Common Stock immediately theretofore receivable upon
the conversion of such share or shares of Series A Convertible Preferred Stock,
such shares of stock, securities or assets as may be issued or payable with
respect to or in exchange for a number of outstanding shares of such Common
Stock equal to the number of shares of such Common Stock immediately theretofore
receivable upon such conversion had such reorganization or reclassification not
taken place, and in any such case appropriate provisions shall be made with
respect to the rights and interests of such holder to the end that the
provisions hereof (including without limitation provisions for adjustments of
the Conversion Price) shall thereafter be applicable, as nearly as may be, in
relation to any shares of stock, securities or assets thereafter deliverable
upon the exercise of such conversion rights.

            6H. Failure to Redeem. If the Corporation fails, for any reason or
for no reason, to redeem on the Redemption Date (as defined in paragraph 7) all
of the then outstanding shares of Series A Convertible Preferred Stock in
accordance with the terms and conditions of paragraph 7, the Conversion Price
then in effect shall be immediately reduced to an amount equal to 90% thereof.
Thereafter, until such redemption has been made in full in accordance with such
terms and conditions, the Conversion Price shall be further reduced on the 90th
day following the Redemption Date and at the end of each 90-day period
thereafter to an amount equal to 90% of the Conversion Price in effect
immediately prior to each such reduction.

            6I. Notice of Adjustment. Upon any adjustment of the Conversion
Price, then and in each such case the Corporation shall give written notice
thereof, by first class mail, postage prepaid, or by telex to non-U.S.
residents, addressed to each holder of shares of Series A Convertible Preferred
Stock at the address of such holder as shown on the books of the Corporation,
which notice shall state the Conversion Price resulting from such adjustment,
setting forth in reasonable detail the method upon which such calculation is
based.

            6J. Other Notices. In case at any time:

                (1) the Corporation shall declare any dividend upon its Common
      Stock payable in cash or stock or make any other distribution to the
      holders of its Common Stock;


<PAGE>
                                       -9-


                (2) the Corporation shall offer for subscription pro rata to the
      holders of its Common Stock any additional shares of stock of any class or
      other rights;

                (3) there shall be any capital reorganization or
      reclassification of the capital stock of the Corporation, or a
      consolidation or merger of the Corporation with or into, or a sale of all
      or substantially all its assets to, another entity or entities; or

                (4) there shall be a voluntary or involuntary dissolution,
      liquidation or winding up of the corporation;

then, in any one or more of said cases, the Corporation shall give, by first
class mail, postage prepaid, or by telex to non-U.S. residents, addressed to
each holder of any shares of Series A Convertible Preferred Stock at the address
of such holder as shown on the books of the Corporation, (a) at least 20 days'
prior written notice of the date on which the books of the Corporation shall
close or a record shall be taken for such dividend, distribution or subscription
rights or for determining rights to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding up, at least 20
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause (a) shall also specify, in the
case of any such dividend, distribution or subscription rights, the date on
which the holders of Common Stock shall be entitled thereto and such notice in
accordance with the foregoing clause (b) shall also specify the date on which
the holders of Common Stock shall be entitled to exchange their Common Stock for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up, as the case may be.

            6K. Stock to be Reserved. The Corporation will at all times reserve
and keep available out of its authorized Common Stock, solely for the purpose of
issuance upon the conversion of Series A Convertible Preferred Stock as herein
provided, such number of shares of Common Stock as shall then be issuable upon
the conversion of all outstanding shares of Series A Convertible Preferred
Stock. The Corporation covenants that all shares of Common Stock which shall be
so issued shall be duly and validly issued and fully paid and nonassessable and
free from all taxes, liens and charges with respect to the issue thereof, and,
without limiting the generality of the foregoing, the Corporation covenants that
it will from time to time take all such action as may be requisite to assure
that the par value per share of the Common Stock is at all times equal to or
less than the Conversion Price in effect at the time. The Corporation will take
all such action as may be necessary to assure that all such shares of Common
Stock may be so issued without violation of any applicable law or regulation, or
of any requirement of any national securities exchange upon which the Common
Stock may be listed. The Corporation will not take any action which results in
any adjustment of the Conversion Price if the total number of shares of Common
Stock issued and issuable after such action upon conversion of the Series A
Convertible Preferred Stock would exceed the total number of shares of Common
Stock then authorized by the Restated Certificate of Incorporation.

                                      -10-


            6L. No Reissuance of Series A Convertible Preferred Stock. Shares of
Series A Convertible Preferred Stock which are converted into shares of Common
Stock as provided herein shall not be reissued.

            6M. Issue Tax. The issuance of certificates for shares of Common
Stock upon conversion of Series A Convertible Preferred Stock shall be made
without charge to the holders thereof for any issuance tax in respect thereof,
provided that the Corporation shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than that of the holder of the Series A Convertible
Preferred Stock which is being converted.

            6N. Closing of Books. The Corporation will at no time close its
transfer books against the transfer of any Series A Convertible Preferred Stock
or of any shares of Common Stock issued or issuable upon the conversion of any
shares of Series A Convertible Preferred Stock in any manner which interferes
with the timely conversion of such Series A Convertible Preferred Stock, except
as may otherwise be required to comply with applicable securities laws.

            6O. Definition of Common Stock. As used in this paragraph 6, the
term "Common Stock" shall mean and include the Corporation's authorized Common
Stock, par value $.01 per share, as constituted on the date of filing of these
terms of the Series A Convertible Preferred Stock, and shall also include any
capital stock of any class of the Corporation thereafter authorized which shall
not be limited to a fixed sum or percentage of par value in respect of the
rights of the holders thereof to participate in dividends or in the distribution
of assets upon the voluntary or involuntary liquidation, dissolution or winding
up of the Corporation; provided that the shares of Common Stock receivable upon
conversion of shares of Series A Convertible Preferred Stock shall include only
shares designated as Common Stock of the Corporation on the date of filing of
this instrument, or in case of any reorganization or reclassification of the
outstanding shares thereof, the stock, securities or assets provided for in
subparagraph 6G.

            6P. Mandatory Conversion. If at any time the Corporation shall
effect a firm commitment underwritten public offering of shares of Common Stock
in which (i) the aggregate price paid for such shares by the public shall be at
least $5,000,000 and (ii) the price paid by the public for such shares shall be
at least $10.50 per share (appropriately adjusted to reflect the occurrence of
any event described in subparagraph 6F), then effective upon the closing of the
sale of such shares by the Corporation pursuant to such public offering, all
outstanding shares of Series A Convertible Preferred Stock shall automatically
convert to shares of Common Stock.

         7. Redemption. The shares of Series A Convertible Preferred Stock shall
be redeemed as follows:

            7A. Mandatory Redemption. On December 31, 1994, the Corporations

<PAGE>
                                      -11-


            7B. Optional Redemption. At any time after December 31, 1992, the
Corporation shall have the right, at its sole option, to redeem from each holder
of shares of Series A Convertible Preferred Stock, all of the shares of Series A
Convertible Preferred Stock held by such holder on the date of such redemption.
The date of a redemption pursuant to Section 7A or 7B is hereinafter referred to
as the "Redemption Date."

            7C. Redemption Price and Payment. The Series A Convertible Preferred
Stock to be redeemed on the Redemption Date shall be redeemed by paying for each
share in cash an amount equal to $3.00 per share plus, in the case of each
share, an amount equal to all Accruing Dividends unpaid thereon (whether or not
declared) and any other dividends declared but unpaid thereon, computed to the
Redemption Date, such amount being referred to as the "Redemption Price". Such
payment shall be made in full on the Redemption Date to the holders entitled
thereto.

            7D. Redemption Mechanics. At least 20 but not more than 30 days
prior to the Redemption Date, written notice (the "Redemption Notice") shall be
given by the Corporation by mail, postage prepaid, or by telex to non-U.S.
residents, to each holder of record (at the close of business on the business
day next preceding the day on which the Redemption Notice is given) of shares of
Series A Convertible Preferred Stock notifying such holder of the redemption and
specifying the Redemption Price, the Redemption Date and the place where said
Redemption Price shall be payable. The Redemption Notice shall be addressed to
each holder at his address as shown by the records of the Corporation. From and
after the close of business on the Redemption date, unless there shall have been
a default in the payment of the Redemption Price, all rights of holders of
shares of Series A Convertible Preferred Stock (except the right to receive the
Redemption Price) shall cease with respect to such shares, and such shares shall
not thereafter be transferred on the books of the Corporation or be deemed to be
outstanding for any purpose whatsoever. If the funds of the Corporation legally
available for redemption of shares of Series A Convertible Preferred Stock on
the Redemption Date are insufficient to redeem the total number of outstanding
shares of Series A Convertible Preferred Stock, the holders of shares of Series
A Convertible Preferred Stock shall share ratably in any funds legally available
for redemption of such shares according to the respective amounts which would be
payable with respect to the full number of shares owned by them if all such
outstanding shares were redeemed in full. The shares of Series A Convertible
Preferred Stock not redeemed shall remain outstanding and entitled to all rights
and preferences provided herein. At any time thereafter when additional funds of
the Corporation are legally available for the redemption of such shares of
Series A Convertible Preferred Stock, such funds will be used, at the end of the
next succeeding fiscal quarter, to redeem the balance of such shares, or such
portion thereof for which funds are then legally available, on the basis set
forth above.

            7E. Redeemed or Otherwise Acquired Shares to be Retired. Any shares
of Series A Convertible Preferred Stock redeemed pursuant to this paragraph 7 or
otherwise acquired by the Corporation in any manner whatsoever shall be canceled
and shall not under any circumstances be reissued; and the Corporation may from
time to time take such appropriate corporate action as may be necessary to
reduce accordingly the number of authorized shares of Series A Convertible
Preferred Stock.

         8. Amendments. No provision of these terms of the Series A Convertible
Preferred Stock may be amended, modified or waived without the written consent
or affirmative vote of the holders of at least two-thirds of the then
outstanding shares of Series A Convertible Preferred Stock.

                                       -3-


affiliated corporation (in the case of a transferor that is a corporation). Each

Sections 5, 6, 13(a) and 13(d), the term "Restricted Stock" shall be deemed to
include the number of shares of Restricted Stock which would be issuable to a
holder of Preferred Stock upon conversion of all shares of Preferred Stock held
by such holder at such time, provided, however, that the only securities which
the Company shall be required to register pursuant hereto shall be shares of
Common Stock, and provided, further, however, that in any underwritten public
offering contemplated by this Section 4 or Sections 5 and 6, the holders of
Preferred Stock shall be entitled to sell such Preferred Stock to the
underwriters for conversion and sale of the shares of Common Stock issued upon
conversion thereof. Notwithstanding anything to the contrary contained herein,
no request may be made under this Section 4 within 180 days after the effective
date of a registration statement filed by the Company covering a firm commitment
underwritten public offering in which the holders of Restricted Stock shall have
been entitled to join pursuant to Sections 5 or 6 and in which there shall have
been effectively registered all shares of restricted Stock as to which
registration shall have been requested.

            (b) Following receipt of any notice under this Section 4, the
Company shall immediately notify all holders of Restricted Stock from whom
notice has not been received and shall use its best efforts to register under
the Securities Act, for public sale in accordance with the method of disposition
specified in such notice from requesting holders, the number of shares of
Restricted Stock specified in such notice (and in all notices received by the
Company from other holders within 30 days after the giving of such notice by the
Company). If such method of disposition shall be an underwritten public
offering, the holders of a majority of the shares of Restricted Stock to be sold
in such offering may designate the managing underwriter of such offering,
subject to the approval of the Company, which approval shall not be unreasonably
withheld or delayed. The company shall be obligated to register Restricted Stock
pursuant to this Section 4 of two occasions only, provided, however, that such
obligation shall be deemed 


<PAGE>
                                       -4-


satisfied only when a registration statement covering all shares of Restricted
Stock specified in notices received as aforesaid, for sale in accordance with
the method of disposition specified by the requesting holders, shall have become
effective and, if such method of disposition is a firm commitment underwritten
public offering, all such shares shall have been sold pursuant thereto.

            (c) The Company shall be entitled to include in any registration
statement referred to in this Section 4, for sale in accordance with the method
of disposition specified by the requesting holders, shares of Common Stock to be
sold by the Company for its own account, except as and to the extent, that, in
the opinion of the managing underwriter (if such method of disposition shall be
an underwritten public offering), such inclusion would adversely affect the
marketing of the Restricted Stock to be sold. Except for registration statements
on Form S-4, S-8 or nay successor thereto, or except for a registration
statement of shares of Common Stock underlying warrants, options, preferred
stock and shares sold on private placement wherein the Company committed to
include such shares in a registration statement, the Company will not file with
the Commission any other registration statement with respect to its Common
Stock, whether for its own account or that of other shareholders, from the date
of receipt of a notice from requesting holders pursuant to this Section 4 until
the completion of the period of distribution of the registration contemplated
thereby.

         5. Incidental Registration. If the Company at any time (other than
pursuant to Section 4 or Section 6) proposes to register any of its securities
under the Securities Act for sale to the pubic, whether for its own account or
for the account of other security holders or both (except with respect to
registration statements on Forms S-4, S-8 or another form not available for
registering the Restricted Stock for sale to the public), each such time it will
give written notice to all holders of outstanding Restricted Stock of its
intention so to do. Upon the written request of any such holder, received by the
Company within 30 days after the giving of any such notice by the Company, to
register any of its Restricted Stock (which request shall state the intended
method of disposition thereof), the Company will use its best efforts to cause
the Restricted Stock as to which registration shall have been so requested t be
included in the securities to be covered by the registration statement proposed
to be filed by the Company, all to the extent requisite to permit the sale or
other disposition by the holder (in accordance with its written request) of such
Restricted Stock so registered. In the event that nay registration pursuant to
this Section 5 shall be, in whole or in part, an underwritten public offering of
Common Stock, the number of shares of Restricted Stock to be included in such an
underwriting may be reduced (pro rata among the requesting holders based upon
the number of shares of Restricted Stock owned by such holders) if and to the
extent that the managing underwriter shall be of the opinion that such inclusion
would adversely affect the marketing of the securities to be sold by the Company
therein provided, however, that such number of shares of Restricted Stock shall
not be reduced if any shares are to be included in such underwriting for the
account of any person other than the Company or requesting holders of Restricted
Stock, and provided, further, however, that in no event may less than one-third
of the total number of shares of Common Stock to be included in such
underwriting be made available for shares of Restricted Stock. Notwithstanding
the foregoing provisions, the Company may withdraw any registration statement
referred to in this Section 5 without thereby incurring any liability to the
holders of Restricted Stock.

                                       -5-


         6. Registration on Form S-3. If at any time (i) a holder or holders of
Preferred Stock (other than Preferred Stock covered under the Evergreen
Registration) or Restricted Stock request that the Company file a registration
statement on Form S-3 or any successor thereto for a public offering of all or
any portion of the shares of Restricted Stock held by such requesting holder or
holders, the reasonably anticipated aggregate price to the public of which would
exceed $500,000, and (ii) the Company is a registrant entitled to use Form S-3
or any successor thereto to register such shares, then the Company shall use its
best efforts to register under the Securities Act on Form S-3 or any successor
thereto, for public sale in accordance with the method of disposition specified
in such notice, the number of shares of Restricted Stock specified in such
notice. Whenever the Company is required by this Section 6 to use its best
efforts to effect the registration of Restricted Stock, each of the procedures
and requirements of Section 4 (including but not limited to the requirement that
the company notify all holders of Restricted Stock from whom notice has not been
received and provide them with the opportunity to participate in the offering)
shall apply to such registration, provided, however, that the requirements
contained in the first sentence of Section 4(a) shall not apply to any
registration on Form S-3 which may be requested and obtained under this Section
6. The Company shall be obligated to register Restricted Stock pursuant to this
Section 6 on ten occasions only, provided, however, that such obligation shall
be deemed satisfied only when a registration statement covering all shares of
Restricted Stock specified in notices received as aforesaid, for sale in
accordance with the method of disposition specified by the requesting holders,
shall have become effective and, if such method of disposition is a firm
commitment public offering, all such shares shall have been sold pursuant
thereto.

         7. Registration Procedures. If and whenever the Company is required by
the provisions of Sections 4, 5 or 6 to use its best efforts to effect the
registration of any shares of Restricted Stock under the Securities Act, the
Company will, as expeditiously as possible:

            (a) prepare and file with the Commission a registration statement
(which, in the case of an underwritten public offering pursuant to Section 4,
shall be on Form S-1 or other form of general applicability satisfactory to the
managing underwriter selected as therein provided) with respect to such
securities and use its best efforts to cause such registration statements to
become and remain effective for the period of the distribution contemplated
thereby (determined as hereinafter provided);

            (b) prepare and file with the commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
the period specified in paragraph (a) above and comply with the provisions of
the Securities Act with respect to the disposition of all Restricted Stock
covered by such registration statement in accordance with the sellers' intended
method of disposition set forth in such registration statement for such period;

            (c) furnish to each seller of Restricted Stock and to each
underwriter such number of copies of the registration statement and the
prospectus included therein (including each preliminary prospectus) as such
persons reasonably may request in order to facilitate the public sale or other
disposition of the Restricted Stock covered by such registration statement;


<PAGE>
                                       -6-


            (d) use its best efforts to register or qualify the Restricted Stock
covered by such registration statement under the securities or "blue sky" laws
of such jurisdictions as the sellers of Restricted Stock, or, in the case of an
underwritten public offering, the managing underwriter reasonably shall request,
provided, however, that the Company shall not for any such purpose be required
to qualify generally to transact business as a foreign corporation in any
jurisdiction where it is not so qualified or to consent to general service of
process in any such jurisdiction;

            (e) use its best efforts to list the Restricted Stock covered by
such registration statement with any securities exchange on which the Common
Stock of the Company is then listed;

            (f) immediately notify each seller of Restricted Stock and each
underwriter under such registration statement, at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of the
happening of any event of which the Company has knowledge as a result of which
the prospectus contained in such registration statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing;

            (g) if the offering is underwritten and at the request of any seller
of Restricted Stock, use its best efforts to furnish on the date that such
Restricted Stock is delivered to the underwriters for sale pursuant to such
registration: (i) an opinion dated such date of counsel representing the Company
for the purposes of such registration, addressed to the underwriters and to such
seller, stating that such registration statement has become effective under the
Securities Act and that (A) to the best knowledge of such counsel, no stop order
suspending the effectiveness thereof has been issued and no proceedings for that
purpose have been instituted or are pending or contemplated under the Securities
Act, (B) the registration statement, the related prospectus and each amendment
or supplement thereof comply as to conform in all material respects with the
requirements of the Securities Act (except that such counsel need not express
any opinion as to financial statements contained therein) and (C) to such other
effects as reasonably may be requested by counsel for the underwriters or by
such seller or its counsel and (ii) a letter dated such date from the
independent public accountants retained by the Company, addressed to the
underwriters and to such seller, stating that they are independent public
accountants within the meaning of the Securities Act and that, in the opinion of
such accountants, the financial statements of the Company included in the
registration statement or the prospectus, or any amendment or supplement
thereof, comply as to form in all material respects with the applicable
accounting requirements of the Securities Act, and such letter shall
additionally cover such other financial matters (including information as to the
period ending no more than five business days prior to the date of such letter)
with respect to such registration as such underwriters reasonably may request;
and

            (h) make available for inspection by each seller of Restricted
Stock, any underwriter participating in any distribution pursuant to such
registration statement, and any 


<PAGE>
                                       -7-


attorney, accountant or other agent retained by such seller or underwriter, all
financial and other records, pertinent corporate documents and properties of the
Company, and cause the Company's officers, directors and employees to supply all
information reasonably requested by any such seller, underwriter, attorney,
accountant or agent in connection with such registration statement.

         For purposes of Section 7(a) and 7(b) and of Section 4(c), the period
of distribution of Restricted Stock in a firm commitment underwritten public
offering shall be deemed to extend until each underwriter has completed the
distribution of all securities purchased by it, and the period of distribution
of Restricted Stock in any other registration shall be deemed to extend until
the earlier of the sale of all Restricted Stock covered thereby and 120 days
after the effective date thereof.

         In connection with each registration hereunder, the sellers of
Restricted Stock will furnish to the Company in writing such information with
respect to themselves and the proposed distribution by them as reasonably shall
be necessary in order to assure compliance with federal and applicable state
securities laws.

         In connection with each registration pursuant to Sections 4, 5 or 6
covering an underwritten public offering, the Company and each seller agree to
enter into a written agreement with the managing underwriter selected in the
manner herein provided in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
underwriter and companies of the Company's size and investment stature.

         8. Expenses. All expenses incurred by the Company in complying with
Sections 4, 5 and 6, including, without limitation, all registration and filing
fees, printing expenses, fees and disbursements of counsel and independent
public accountants for the Company, fees and expenses (including counsel fees)
incurred in connection with complying with state securities or "blue sky" laws,
fees of the National Association of Securities Dealers, Inc., transfer taxes,
fees of transfer agents and registrars, costs of insurance and fees and
disbursements of one counsel for the sellers of Restricted Stock, but excluding
any Selling Expenses, are called "Registration Expenses." All underwriting
discounts and selling commissions applicable to the sale of Restricted Stock are
called "Selling Expenses."

         The Company will pay all Registration Expenses in connection with each
registration statement under Section 4, 5 or 6; provided, however, that the
total amount of all such Registration Expenses borne by the Company shall not
exceed $100,000. All Selling Expenses in connection with each registration
statement under Section 4, 5 or 6 shall be borne by the participating sellers in
proportion to the number of shares sold by each, or by such participating
sellers other than the company (except to the extent the Company shall be a
seller) as they may agree.

         9. Indemnification and Contribution. (a) In the event of a registration
of any of the Restricted Stock under the Securities Act pursuant to Section 4, 5
or 6, the Company will indemnify and hold harmless each seller of such
Restricted Stock thereunder, each underwriter of such Restricted Stock
thereunder and each other person, if any, who controls such seller or



<PAGE>
                                       -8-


underwriter within the meaning of the Securities Act, against any losses,
claims, damages or liabilities, joint or several, to which such seller,
underwriter or controlling person may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such Restricted Stock was registered under the Securities Act
pursuant to Section 4, 5 or 6, any preliminary prospectus or final prospectus
contained therein, or any amendment or supplement 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, and will reimburse each such seller, each such underwriter and each
such controlling person for any legal or other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim, damage,
liability or action, provided, however, that the Company will not be liable in
any such case if and to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission so made in conformity with information
furnished by any such seller, any such underwriter or any such controlling
person in writing specifically for use in such registration statement or
prospectus.

            (b) In the event of a registration of any of the Restricted Stock
under the Securities Act pursuant to Sections 4, 5 or 6, each seller of such
Restricted Stock thereunder, severally and not jointly, will indemnify and hold
harmless the Company, each person, if any, who controls the Company within the
meaning of the Securities Act, each officer of the Company who signs the
registration statement, each director of the Company, each underwriter and each
person who controls any underwriter within the meaning of the Securities Act,
against all losses, claims, damages or liabilities, joint or several, to which
the Company or such officer, director, underwriter or controlling person may
become subject under Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of any material
fact contained in the registration statement under which such Restricted Stock
was registered under the Securities Act pursuant to Sections 4, 5 or 6, any
preliminary prospectus or final prospectus contained therein, or any amendment
or supplement 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, and will reimburse the
Company and each such officer, director, underwriter and controlling person for
any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action,
provided, however, that such seller will be liable hereunder in any such case if
and only to the extent that any such loss, claim, damage or liability arises out
of or is based upon an untrue statement or alleged untrue statement or omission
or alleged omission made in reliance upon and in conformity with information
pertaining to such seller, as such, furnished in writing to the Company by such
seller specifically for use in such registration statement or prospectus, and
provided, further, however, that the liability of each seller hereunder shall be
limited to the proportion of any such loss, claim, damage, liability or expense
which is equal to the proportion that the public offering price of the shares
sold by such seller under such registration statement bears to the total public
offering price of all securities 


<PAGE>
                                       -9-


sold thereunder, but not in any event to exceed the proceeds received by such
seller from the sale of Restricted Stock covered by such registration statement.

            (c) Promptly after receipt by an indemnified party hereunder 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 hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to such indemnified party other than under this Section 9 and shall only relieve
it from any liability which it may have to such indemnified party under this
Section 9 if and to the extent the indemnifying party is prejudiced by such
omission. In case any such action shall be brought against any indemnified party
and it shall notify the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate in and, to the extent it
shall wish, to assume and undertake the defense thereof with counsel
satisfactory to such indemnified party, and, after notice from the indemnifying
party to such indemnified party of its election so to assume and undertake the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under this Section 9 for any legal expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation and of liaison with counsel so selected, provided,
however, that, if the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be reasonable defenses available to it which are
different from or additional to those available to the indemnifying party or if
the interests of the indemnified party reasonably may be deemed to conflict with
the interests of the indemnifying party, the indemnified party shall have the
right to select a separate counsel and to assume such legal defenses and
otherwise to participate in the defense of such action, with the expenses and
fees of such separate counsel and other expenses related to such participation
to be reimbursed by the indemnifying party as incurred.

            (d) In order to provide for just and equitable contribution to joint
liability under the Securities Act in any case in which either (i) any holder of
Restricted Stock exercising rights under this Agreement or any controlling
person of any such holder, makes a claim for indemnification pursuant to this
Section 9 but it is judicially determined (by the entry of a final judgment or
decree by a court of competent jurisdiction and the expiration of time to appeal
or the denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that this Section 9 provides for
indemnification in such case, or (ii) contribution under the Securities Act may
be required on the part of any such selling holder or any such controlling
person in circumstances for which indemnification is provided under this Section
9; then, and in each such case, the Company and such holder will contribute to
the aggregate losses, claims, damages or liabilities to which they may be
subject (after contribution from others) in such proportion so that such holder
is responsible for the portion represented by the percentage that the public
offering price of its Restricted Stock offered by the registration statement
bears to the public offering price of all securities offered by such
registration statement, and the Company is responsible for the remaining
portion; provided, however, that, in any such case, (A) no such holder will be
required to contribute any amount in excess of the public offering price of all
such Restricted Stock offered by it pursuant to such registration statement; and
(B) no person or entity guilty of fraudulent misrepresentation (within the
meaning 


<PAGE>
                                      -10-


of Section 11(f) of the Securities Act) will be entitled to contribution from
any person or entity who was not guilty of such fraudulent misrepresentation.

         10. Changes in Common Stock or Preferred Stock. If, and as often as,
there is any change in the Common Stock or the Preferred Stock by way of a stock
split, stock dividend, combination or reclassification, or through a merger,
consolidation, reorganization or recapitalization, or by any other means,
appropriate adjustment shall be made in the provisions hereof so that the rights
and privileges granted hereby shall continue with respect to the Common Stock or
the Preferred Stock as so changed.

         11. Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Stock to the public without registration, at all times
after 90 days after any registration statement covering a public offering of
securities of the Company under the Securities Act shall have become effective,
the Company agrees to:

             (a) make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act;

             (b) use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and

             (c) furnish to each holder of Restricted Stock forthwith upon
request a written statement by the Company as to its compliance with the
reporting requirements of such Rule 144 and of the Securities Act and the
Exchange Act, a copy of the most recent annual or quarterly report of the
Company, and such other reports and documents so filed by the Company as such
holder may reasonably request in availing itself of any rule or regulation of
the Commission allowing such holder to sell any Restricted Stock without
registration.

         12. Representations and Warranties of the company. The Company
represents and warrants to you as follows:

             (a) The execution, delivery and performance of this Agreement by
the Company have been duly authorized by all requisite corporate action and will
not violate any provision of law, any order of any court or other agency of
government, the Restated Certificate of Incorporation or By-laws of the Company
or any provision of any indenture, agreement or other instrument to which it or
any of its properties or assets is bound, conflict with, result in a breach of
or constitute (with due notice or lapse of time or both) a default under any
such indenture, agreement or other instrument or result in the creation or
imposition of any lien, charge or encumbrance of any nature whatsoever upon any
of the properties or assets of the Company.


<PAGE>
                                      -11-


             (b) This Agreement has been duly executed and delivered by the
Company and constitutes the legal, valid and binding obligation of the Company,
enforceable in accordance with its terms.

         13. Miscellaneous.

             (a) All covenants and agreements contained in this Agreement by or
on behalf of any of the parties hereto shall bind and inure to the benefit of
the respective successors and assigns of the parties hereto (including without
limitation transferees of any Preferred Stock or Restricted Stock), whether so
expressed or not, provided, however, that registration rights conferred herein
on the holders of Preferred Stock or Restricted Stock shall only inure to the
benefit of a transferee of Preferred Stock or Restricted Stock if (i) there is
transferred to such transferee at least 20% of the total shares of Restricted
Stock originally issued pursuant to the Purchase Agreement to the direct or
indirect transferor of such transferee or (ii) such transferee is a partner,
shareholder or affiliate of a party hereto.

             (b) All notices, requests, consents and other communications
hereunder shall be in writing and shall be mailed by certified or registered
mail, return receipt requested, postage prepaid, or telexed, in the case of
non-U.S. residents, addressed as follows:

                 (i) if to the Company or any other party hereto, at the address
of such party set forth in the Purchase Agreement;

                 (ii) if to any subsequent holder of Preferred Stock or
Restricted Stock, to it at such address as may have been furnished to the
Company in writing by such holder;

or, in any case, at such other address or addresses as shall have been furnished
in writing to the Company (in the case of a holder of Preferred Stock or
Restricted Stock) or to the holders of Preferred Stock or Restricted Stock (in
the case of the Company in accordance with the provisions of this paragraph).

             (c) This Agreement shall be governed by and construed in accordance
with the laws of the State of New York.

             (d) This Agreement may not be amended or modified, and no provision
hereof may be waived, without the written consent of the Company and the holders
of at least two-thirds of the outstanding shares of Restricted Stock.

             (e) This Agreement may be executed in two or more counterparts,
each of which shall be deemed an original, but all of which together shall
constitute one and the same instrument.

             (f) The obligations of the Company to register the shares of
Restricted Stock under Sections 4, 5 or 6 shall terminate on the fifteenth
anniversary of the date of this Agreement.


<PAGE>
                                      -12-


             (g) If requested in writing by the underwriters for the initial
underwritten public offering of securities of the Company, each holder of
Restricted Stock who is a party to this Agreement shall agree not to sell
publicly any shares of Restricted Stock or any other shares of Common Stock
(other than shares of Restricted Stock or other shares of Common Stock being
registered in such offering), without the consent of such underwriters, for a
period of not more than 90 days following the effective date of the registration
statement relating to such offering; provided, however, that all persons
entitled to registration rights with respect to shares of Common Stock who are
not parties to this Agreement, all other persons selling shares of Common Stock
in such offering and all executive officers and directors of the Company shall
also have agreed not to sell publicly their Common Stock under the circumstances
and pursuant to the terms set forth in this Section 13(g).

             (h) Notwithstanding the provisions of Section 7(a), the Company's
obligation to file a registration statement, or cause such registration
statement to become and remain effective, shall be suspended for a period not to
exceed 90 days in any 24-month period if there exists at the time material
non-public information relating to the Company which, in the reasonable opinion
of the Company, should not be disclosed.

             (i) The Company shall not grant to any third party any registration
rights more favorable than any of those contained herein, so long as any of the
registration rights under this Agreement remains in effect.

             (j) If any provision of this Agreement shall be held to be illegal,
invalid or unenforceable, such illegality, invalidity or unenforceability shall
attach only to such provision and shall not in any manner affect or render
illegal, invalid or unenforceable any other provision of this Agreement, and
this Agreement shall be carried out as if any such illegal, invalid or
unenforceable provision were not contained herein.

         Please indicate your acceptance of the foregoing by signing and
returning the enclosed counterpart of this letter, whereupon this Agreement
shall be a binding agreement between the Company and you.

                                Very truly yours,

                                MEDICAL STERILIZATION, INC.

                           STOCK RESTRICTION AGREEMENT

         AGREEMENT, made as of the 30th day of December, 1989, by and among
Medical Sterilization, Inc., a New York corporation (the "Company"), Kennard H.
Morganstern (the "Shareholder"), and the persons listed as Investors in the
signature pages hereto (collectively, the "Investors" and individually, an
"Investor").

         WHEREAS, the shareholder is the holder of an aggregate of 257,900
shares of common stock, $.01 par value, of the Company (the "Common Stock");

         WHEREAS, the Investors are acquiring an aggregate of 1,500,00 shares of
Series A Convertible Preferred Stock (the "Preferred Stock") and Common Stock
Purchase Warrants (the "Warrants") for the purchase (subject to adjustment as
provided therein) of 1,500,000 shares of Common Stock, pursuant to the terms of
a Preferred Stock and Warrant Purchase Agreement dated the date hereof between
the Company and the Investors (the "Purchase Agreement"); and

         WHEREAS, it is a condition to the obligations of the Investors under
the Purchase Agreement that this Agreement be executed by the parties hereto,
and the parties are willing to execute this Agreement and to be bound by the
provisions hereof;

         NOW THEREFORE, in consideration of the foregoing, the agreements set
forth below, and the parties' desire to provide for continuity of ownership of
the Company to further the interests of the Company and its present and future
shareholders, the parties hereby agree with each other as follows:

         1. Certain Defined Terms. As used in this Agreement, the following
terms shall have the following respective meanings:

            (a) "Stock" shall mean and include all shares of Common Stock, and
all other securities of the Company which may be issued in exchange for or in
respect of shares of Common Stock (whether by way of stock split, stock
dividend, combination, reclassification, reorganization, or any other means).

            (b) "Shares" shall mean and include all shares of Stock now owned or
hereafter acquired by either (I) the Shareholder or (ii) any Investor.

         2. Prohibited Transfers. The Shareholder shall not sell, assign,
transfer, pledge, hypothecate, mortgage, encumber or dispose of an aggregate of
more than five (5%) percent of his Shares, in any twelve month period without
the prior written consent of Investors owning at least two-thirds of the Shares
owned by all Investors. Notwithstanding the foregoing, the Shareholder may (a)
transfer all or any of his shares (i) by way of gift to any member of his family
or to any trust for the benefit of any such family member of the Shareholder,
provided that any such transferee shall agree in writing with the Company and
the Investors, as a condition to 


<PAGE>
                                       -2-


such transfer, to be bound by all of the provisions of this Agreement to the
same extent as if such transferee were the Shareholder, or (ii) by will or the
laws of descent and distribution, in which event each such transferee shall be
bound by all of the provisions of this Agreement to the same extent as if such
transferee were the Shareholder or (b) pledge any or all of his Shares to a bank
or other institutional lender as security for the payment by the Company of any
amount owed by the Company to such Bank or institutional lender. As used herein,
the word "family" shall include any spouse, lineal ancestor or descendant,
brother or sister.

         3. Further Limitation as to Transfers by the Shareholder. In addition
to the other restrictions provided in this Agreement, the Shareholder agrees
that he shall not sell any Shares at a price per share of less than $7.00
(subject to equitable adjustment for any stock split, stock dividend,
combination of shares or the like and based upon Common Stock or Common Stock
equivalents).

         4. Term. This Agreement shall terminate ((a) immediately prior to the
consummation of a firm commitment underwritten public offering pursuant to an
effective registration statement on Form S-1 or Form S-3 (or their then
equivalents) under the Securities Act of 1933, as amended, pursuant to which the
aggregate price paid by the public for the purchase of Stock is at least
$5,000,000 and the price paid by the public for each share of Common Stock is
$10.50 (subject to equitable adjustment for any stock split, stock dividend,
combination of shares or the like and based on Common Stock and Common Stock
equivalents) or (b) the tenth anniversary of the date of this Agreement,
whichever occurs first.

         5. Specific Enforcement. The Shareholder expressly agrees that the
Investors and the Company will be irreparably damaged if this Agreement is not
specifically enforced. Upon a breach or threatened breach of the terms,
covenants and/or conditions of this Agreement by the Shareholder, the Investors
and the Company shall, in addition to all other remedies, each be entitled to a
temporary or permanent injunction, without showing any actual damage, and/or a
decree for specific performance, in accordance with the provisions hereof.

         6. Legend. Each certificate evidencing any of the Shares shall bear a
legend substantially as follows:

            "The shares represented by this certificate are subject to
restrictions on transfer and may not be sold, exchanged, transferred, pledged,
hypothecated or otherwise disposed of except in accordance with and subject to
all the terms and conditions of a certain Stock Restriction Agreement dated as
of        , 1989, a copy of which the Company will furnish to the holder of this
certificate upon request and without charge."

         7. Notices. Notices given hereunder shall be deemed to have been duly
given on the date of personal delivery or on the date of postmark if mailed by
certified or registered mail, return receipt requested, to the party being
notified at his or its address specified on the applicable signature page hereto
or such other address as the addressee may subsequently notify the other parties
of in writing.

                                       -3-


         8. Entire Agreement and Amendments. This Agreement constitutes the
entire agreement of the parties with respect to the subject matter hereof and
neither this Agreement nor any provision hereof may be waived, modified, amended
or terminated except by a written agreement signed by the parties hereto;
provided, however, that Investors owning at least two-thirds of the Shares owned
by all Investors may effect any such waiver, modification, amendment or
termination on behalf of all of the Investors. To the extent any term or other
provision of any other indenture, agreement, or instrument by which any party
hereto is bound conflicts with this Agreement, this Agreement shall have
precedence over such conflicting term or provision.

         9. Governing Law; Successors and Assigns. This Agreement shall be
governed by the laws of the State of New York and shall be binding upon the
heirs, personal representatives, executors, administrators, successors and
assigns of the parties.

         10. Waivers. No waiver of any breach or default hereunder shall be
considered valid unless in writing, and no such waiver shall be deemed a waiver
of any subsequent breach or default of the same or similar nature.

         11. Severability. If any provision of this Agreement shall be held to
be illegal, invalid or unenforceable, such illegality, invalidity or
unenforceability shall attach only to such provision and shall not in any manner
affect or render illegal, invalid or unenforceable any other provision of this
Agreement, and this Agreement shall be carried out as if any such illegal,
invalid or unenforceable provision were not contained herein.

         12. Captions. Captions are for convenience only and are not deemed to
be part of this Agreement.

         13. Continuation of Employment. Nothing in this Agreement shall create
an obligation on the Company or the Investors to continue the Shareholder's
employment with the Company.

         14. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         IN WITNESS WHEREOF, this Agreement has been executed as of the date and
year first above written.

                        MEDICAL STERILIZATION, INC. (MSI)

                                    AGREEMENT

         In consideration of the compensation and other benefits of my
employment by MSI, and of other valuable consideration, I agree with MSI as
follows:

                                EMPLOYMENT BY MSI

         During my MSI employment I shall devote my working time and best
efforts to the service of MSI and shall comply with the policies and procedures
of MSI, including those relating to security and employee conduct, and I shall
not engage in any planning or other business or technical activity, competitive
with or in conflict with the business interests of MSI.

                            CONFIDENTIAL INFORMATION

         As used herein, "Confidential Information" means all technical and
business information of MSI, whether patentable or not, which is of a
confidential, trade secret and/or proprietary character and which is either
developed by me (alone or with others) or to which I have had access during my
employment. "Confidential Information" shall also include confidential
evaluations of, and the confidential use of non-use by MSI, of technical or
business information in the public domain.

         I shall use my best efforts and diligence both during and after my MSI
employment to protect the confidential, trade secret and/or proprietary
character of all Confidential Information. I shall not, directly or indirectly,
use (for myself or another) or disclose any Confidential Information for so long
as it shall remain proprietary or protectible as confidential or trade secret
information, except as may be necessary for the performance of my MSI duties.

         I shall deliver promptly to MSI, at the termination of my employment,
or at any other time at MSI's request, without retaining any copies, all
documents and other material in my possession relating, directly or indirectly,
to any Confidential Information.

         Each of my obligations in this section shall also apply to the
confidential, trade secret and proprietary information learned or acquired by me
during my employment from others with whom MSI has a business relationship.

         I understand that I am not to disclose to MSI, or use for its benefit,
any of the confidential, trade secret or proprietary information of others
including any of my former employers.

<PAGE>
                                       -2-


                              COMPETITIVE ACTIVITY

         I shall not, directly or indirectly (whether as owner, partner,
consultant, employee or otherwise), at any time during the period of my
employment with MSI, engage in or contribute my knowledge to any work or
activity that involves a product, process, apparatus, service or development
which is then competitive with or similar to a product, process, apparatus,
service or development on which I worked or with respect to which I had access
to Confidential Information while at MSI at any time during the period of my
employment ("Competitive Work"). Following the expiration of my employment, I
shall continue to be obligated under the "Confidential Information" section of
this Agreement not to use or to disclose Confidential Information so long as it
shall remain proprietary or protectible as confidential or trade secret
information.

         During my employment by MSI, and for a period of two years there after,
I shall not, directly or indirectly, induce or attempt to induce a salaried
employee of MSI to accept employment or affiliation involving Competitive Work
with another firm or corporation of which I am an employee, owner, partner or
consultant.

                        IDEAS, INVENTIONS OR DISCOVERIES

         I shall promptly disclose to MSI all ideas, inventions or discoveries,
whether or not patentable, which I may conceive or make, alone or with others,
during my employment, whether or not during working hours, and which directly or
indirectly

           (a) relate to matters within the scope of my duties or field of
               responsibility during my employment by MSI; or

           (b) are based on my knowledge of the actual or anticipated business
               or interests of MSI; or

           (c) are aided by the use of time, materials, facilities or
               information of MSI.

         Without further compensation but at MSI's expense, I shall give all
testimony and execute all patent applications, rights of priority, assignments
and other documents and in general do all lawful things requested of me by MSI
to enable MSI to obtain, maintain and enforce protection of such ideas,
inventions and discoveries for and in the name of MSI , or its nominee, in all
countries of the world. However, should I render any of these services following
termination of my employment, I shall be compensated at a rate per hour equal to
the base salary I received from MSI at the time of termination and shall be
reimbursed for reasonable out-of-pocket expenses incurred in rendering the
services.

                                  MISCELLANEOUS

                                       -3-


         This Agreement shall be construed under the laws of the State of New
York and shall be binding upon and enforceable against my heirs and legal
representatives and the assignees of any idea, invention or discovery conceived
or made by me.

         To the extent this Agreement is legally enforceable, it shall supersede
all previous agreements covering this subject matter between me and MSI, but
shall not relieve me or such other party form any obligations incurred under any
such previous agreement while in force.

         If any provision of this Agreement is held invalid in any respect, it
shall not affect the validity of any other provision of this Agreement. If any
provision of this Agreement is held to be unreasonable as to time, scope or
otherwise, it shall be construed by limiting and reducing it so as to be
enforceable under then applicable law.

         This Agreement is signed in duplicate, as of the      day of     19  .

                          CERTIFICATE OF INCORPORATION
                                       OF
                           MEDICAL STERILIZATION, INC.

                Under Section 805 of the Business Corporation Law

         We, Kennard H. Morganstern and Harvey Cohen, being respectively the
President and Secretary of Medical Sterilization, Inc., hereby certify:

         (1)      The name of the Corporation is

                           MEDICAL STERILIZATION, INC.

         (2) The Certificate of Incorporation was filed on May 27, 1982 under
the name General Sterilization, Inc. Restated Certificates of Incorporation were
filed on May 12, 1983, August 5, 1983 and May 24, 1989.

         (3) The Certificate of Incorporation is amended by the addition of a
provision stating the number, designation, relative rights, preferences and
limitations of Preferred Shares of a series of the par value of $.01 per share,
as fixed by the Board of Directors before the issuance of such series, under
authority contained in the Certificate of Incorporation and as permitted by
Section 502 of the Business Corporation Law as follows:

         "1. Number of Shares. One Million (1,000,000) shares of authorized
Preferred Stock of the par value of $.01 each shall be issued in and as a series
to be designated "Series A Convertible Preferred Stock". The term Preferred
Stock, as used herein, shall include all of the shares of Preferred Stock
authorized by the Certificate of Incorporation, of which Series A Convertible
Preferred Stock is the first series.


<PAGE>
                                       -2-


         2. Voting.

            2A. General. Except as may be otherwise provided in these terms of
the Series A Convertible Preferred Stock or by law, the Series A Convertible
Preferred Stock shall vote together with all other classes and series of stock
of the Corporation as a single class on all actions to be taken by the
stockholders of the Corporation. Each share of Series A Convertible Preferred
Stock shall entitle the holder thereof to such number of votes per share on each
such action as shall equal the number of shares of Common Stock (including
fractions of a share) into which each share of a Series A Convertible Preferred
Stock is then convertible.

            2B. Board Size. The Corporation shall not, without the written
consent or affirmative vote of the holders of at least two-thirds of the then
outstanding shares of Series A Convertible Preferred Stock, given in writing or
by vote at a meeting, consenting or voting (as the case may be) separately as a
series, increase the maximum number of directors constituting the Board of
Directors to a number in excess of eleven (11).

            2C. Board Seats. The holders of the Series A Convertible Preferred
Stock, voting as a separate series, shall be entitled to elect one (1) director
of the Corporation. The holders of the Common Stock, voting as a separate class,
shall be entitled to elect the remaining directors of the Corporation.
Notwithstanding the foregoing or anything else to the contrary provided in the
Restated Certificate of Incorporation, if the Corporation fails or refuses, for
any reason or for no reason, to redeem on the Redemption Date (as defined in
paragraph 7) all of the then outstanding shares of Series A Convertible
Preferred Stock in accordance with the terms and provisions of paragraph 7, the
holders of the Series A Convertible Preferred Stock, voting as a separate
series, shall be entitled to elect a majority of the directors of the
Corporation. At any meeting (or in a written consent in lieu thereof) held for
the purpose of electing directors, the presence in person or by proxy (or the
written consent) of the holders of a majority of the shares of Series A
Convertible Preferred Stock then outstanding shall constituent a quorum of the
Series A Convertible Preferred Stock for the election of directors to be elected
solely by the holders of the Series A Convertible Preferred Stock or jointly by
the holders of the Series A Convertible Preferred Stock and the Common Stock. A
vacancy in any directorship elected by the holders of the Series A Convertible
Preferred Stock shall be filled only by vote or written consent of the holders
of the Series A Convertible Preferred Stock.

         3. Dividends. The holders of the Series A Convertible Preferred Stock
shall be entitled to receive, out of funds legally available therefor, when and
if declared by the Board of Directors, quarterly dividends at the rate per annum
of $.30 per share (the "Accruing Dividends"). Accruing dividends shall accrue
from day to day, whether or not earned or declared and shall be cumulative from
the date of issuance of the Series A Convertible Preferred Stock.

         4. Liquidation. Upon any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, the holders of the shares of
Series A Convertible Preferred Stock made upon any stock ranking on liquidation
junior to the Series A Convertible Preferred Stock, to be paid an amount 


<PAGE>
                                       -3-


equal to $3.00 per share plus, in the case of each share, an amount equal to all
Accruing Dividends unpaid thereof (whether or not declared) and any other
dividends declared but unpaid thereof, computed to the date payment thereof is
made available such amount payable with respect to one share of Series A
Convertible Preferred Stock being sometimes referred to as the "Liquidation
Preference Payment" and with respect to all shares of Series A Convertible
Preferred Stock being sometimes referred to as the "Liquidation Preferred Stock
being sometimes referred to as the "Liquidation Preference Payments". If upon
such liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, the assets to be distributed among the holders of
Series A Convertible Preferred Stock shall be insufficient to permit payment in
full to the holders of Series A Convertible Preferred Stock of the Liquidation
Preference Payments, then the entire assets of the corporation to be so
distributed shall be distributed ratably among the holders of Series A
Convertible Preferred Stock. Upon any such liquidation, dissolution or winding
up of the Corporation, immediately after the holders of Series A Convertible
Preferred Stock shall have been paid in full the Liquidation Preference
Payments, the remaining net assets of the Corporation available for distribution
shall be distributed ratably among the holders of Series A Convertible Preferred
Stock and Common Stock (with each share of Series A Convertible Preferred Stock
being deemed, for such purpose, to be equal to the number of shares of Common
Stock (including fractions of a share) into which such share of Series A
Convertible Preferred Stock is convertible immediately prior to the close of
business on the business day fixed for such distribution). Written notice of
such liquidation, dissolution or winding up, stating a payment date and the
place where said payments shall be made, shall be given by mail, postage
prepaid, or by telex to non-U.S. residents, not less than 20 days prior to the
payment date stated therein, to the holders of record of Series A Convertible
Preferred Stock, such notice to be addressed to each such holder at its address
as shown by the records of the Corporation. The consolidation or merger of the
Corporation into or with any other entity or entities which results in the
exchange of outstanding shares of the Corporation for securities or other
consideration issued or paid or caused to be issued or paid by any such entity
or affiliate thereof, and the sale or transfer by the Corporation of all or
substantially all its assets, shall be deemed to be a liquidation, dissolution
or winding up of the Corporation within the meaning of the provisions of this
paragraph 4. For purposes hereof, the Common Stock shall rank on liquidation
junior to the Series A Convertible Preferred Stock.

         5. Restrictions. At any time when shares of Series A Convertible
Preferred Stock are outstanding, except where the vote or written consent of the
holders of a greater number of shares of the Corporation is required by law or
by the Restated Certificate of Incorporation, and in addition to any other vote
required by law or the Restated Certificate of Incorporation, without the
approval of the holders of at least two-thirds of the then outstanding shares of
Series A Convertible Preferred Stock, given in writing or by vote at a meeting,
consenting or voting (as the case may be) separately as a series, the
Corporation will not:

the Restated Certificate of Incorporation or by merger, consolidation or
otherwise;

            5B. Consent to any liquidation, dissolution or winding up of the

employees of the Corporation who acquired such shares directly from the
corporation, if each such purchase is made pursuant to contractual rights held

employee and the purchase price does not exceed the original issue price paid by
such former employee to the Corporation for such shares; or

            5E. Redeem or otherwise acquire any shares of Series A Convertible
Preferred Stock except as expressly authorized in paragraph 7 hereof or pursuant
to a purchase offer made pro rata to all holders of the shares of Series A

         6. Conversions. The holders of shares of Series A Convertible Preferred
Stock shall have the following conversion rights:

            6A. Right to Convert. Subject to the terms and conditions of this
paragraph 6, the holder of any share or shares of Series A Convertible Preferred
Stock shall have the right, at its option at any time, to convert any such
shares of Series A Convertible Preferred Stock (except that upon any liquidation
of the Corporation the right of conversion shall terminate at the close of
business on the business day fixed for payment of the amount distributable on
the Series A Convertible Preferred Stock) into such number of fully paid and
nonassessable shares of Common Stock as is obtained by (I) multiplying the
number of shares of Series A Convertible Preferred Stock so to be converted by
$3.00 Series A Convertible Preferred Stock so to be converted by $3.00 and (ii)
dividing the result by the conversion price of $3.00 per share or, in case an
adjustment of such price has taken place pursuant to the further provisions of
this paragraph 6, thereby the conversion price as last adjusted and in effect at
the date any share or shares of Series A Convertible Preferred Stock are
surrendered for conversion (such price, or 


<PAGE>
                                       -5-


such price as last adjusted, being referred to as the "Conversion Price"). Such
rights of conversion shall be exercised by the holder thereof by giving written
notice that the holder elects to convert a stated number of shares of Series A
Convertible Preferred Stock into Common Stock and by surrender of a certificate
or certificates for the shares so to be converted to the Corporation at its
principal office (or such other office or agency of the Corporation as the
Corporation may designate by notice in writing to the holders of the Series A
Convertible Preferred Stock) at any time during its usual business hours on the
date set forth in such notice, together with a statement of the name or names
(with address) in which the certificate or certificates for shares of Common
Stock shall be issued.

         6B. Issuance of Certificates; Time Conversion Effected. Promptly after
the receipt of the written notice referred to in subparagraph 6A and surrender
of the certificate or certificates for the share or shares of Series A
Convertible Preferred Stock to be converted, the Corporation shall issue and
deliver, or cause to be issued and delivered, to the holder, registered in such
name or names as such holder may direct, a certificate or certificates for the
number of whole shares of Common Stock issuable upon the conversion of such
shares of Common Stock issuable upon the conversion of such share or shares of
Series A Convertible Preferred Stock. To the extent permitted by law, such
conversion shall be deemed to have been effected and the Conversion Price shall
be determined as of the close of business on the date on which such written
notice shall have been received by the Corporation and the certificate or
certificates for such share or shares shall have been surrendered as aforesaid,
and at such time the rights of the holder of such share or shares of Series A
Convertible Preferred Stock shall cease, and the person or persons in whose name
or names any certificate or certificates for shares of Common Stock shall be
issuable upon such conversion shall be deemed to have become the holder or
holders of record of the shares represented thereby.

         6C. Fractional Shares; Dividends; Partial Conversion. No fractional
shares shall be issued upon conversion of Series A Convertible Preferred Stock
into Common Stock and no payment or adjustment shall be made upon any conversion
on account of any cash dividends on the Common Stock issued upon such
conversion. At the time of each conversion, the Corporation shall pay in cash an
amount equal to all dividends, excluding Accruing Dividends, accrued and unpaid
on the shares of Series A Convertible Preferred Stock surrendered for conversion
to the date upon which such conversion is deemed to take place as provided in
subparagraph 6B. In case the number of shares of Series A Convertible Preferred
Stock represented by the certificate or certificates surrendered pursuant to
subparagraph 6A exceeds the number of shares converted, the Corporation shall,
upon such conversion, execute and deliver to the holder, at the expense of the
Corporation, a new certificate or certificates for the number of shares of
Series A Convertible Preferred Stock represented by the certificate or
certificates surrendered which are not to be converted. If any fractional share
of Common Stock would, except for the delivered upon such conversion, the
Corporation, in lieu of delivering such fractional share, shall pay to the
holder surrendering the Series A Convertible Preferred Stock for conversion an
amount in cash equal to the current market price of such fractional share as
determined in good faith by the Board of Directors of the Corporation.

         6D. Adjustment of Price Upon Issuance of Common Stock. Except as
provided in subparagraph 6E, if and whenever the Corporation shall issue or
sell, or is, in accordance with subparagraph 6D(1) through 6D(7), deemed to have
issued or sold, any shares of Common Stock for a consideration per share less
than the Conversion Price in effect immediately prior to the time of such issue
or sale, then, forthwith upon such issue or sale, the Conversion Price shall be
reduced to the price at which the Corporation issued or sold, or is deemed to
have issued or sold, such shares of Common Stock.

         For purposes of this subparagraph 6D, the following subparagraphs 6D(1)
to 6D(7) shall also be applicable:

                  6D(1) Issuance of Rights or Options. In case at any time the
         Corporation shall in any manner grant (whether directly or by
         assumption in a merger or otherwise) any warrants or other rights to
         subscribe for or to purchase, or any options for the purchase of,
         Common Stock or any stock or security convertible into or exchangeable
         for Common Stock (such warrants, rights or options being called
         "Options" and such convertible or exchangeable stock or securities
         being called "Convertible Securities") whether or not such Options or
         the right to convert or exchange any such Convertible Securities are
         immediately exercisable, and the price per share for which Common Stock
         is issuable upon the exercise of such Options or upon the conversion or
         exchange of such Convertible Securities (determined by dividing (i) the
         total amount, if any, received or receivable by the Corporation as
         consideration for the granting of such Options, plus the minimum
         aggregate amount of additional consideration payable to the Corporation
         upon the exercise of all such Options, plus, in the case of such
         Options which relate to Convertible Securities, the minimum aggregate
         amount of additional consideration, if any, payable upon the issue or
         sale or such convertible Securities and upon the conversion or exchange
         thereof, by (ii) the total maximum number of shares of Common Stock
         issuable upon the exercise of such Options or upon the conversion or
         exchange of all such Convertible Securities issuable upon the exercise
         of such Options) shall be less than the Conversion price in effect
         immediately prior to the time of the granting of such Options, then the
         total maximum number of shares of Common Stock issuable upon the
         exercise of such Options or upon conversion or exchange or the total
         maximum amount of such Convertible Securities issuable upon the
         exercise of such Options shall be deemed to have been issued for such
         price per share as of the date of granting of such Options or the
         issuance of such Convertible Securities and thereafter shall be deemed
         to be outstanding. Except as the Conversion Price shall be made upon
         the actual issue of such Common Stock or of such Convertible Securities
         upon exercise of such Options or upon the actual issue of such Common
         Stock upon conversion or exchange of such Convertible Securities.

                  6D(2) Issuance of Convertible Securities. In case the
         Corporation shall in any manner issue (whether directly or by
         assumption in a merger or otherwise) or sell any Convertible
         Securities, whether or not the rights to exchange or convert any such
         Convertible Securities are immediately exercisable, and the price per
         share for which Common Stock is issuable upon such conversion or
         exchange (determined by dividing 


<PAGE>
                                       -7-


         (i) the total amount received or receivable by the Corporation as
         consideration for the issue or sale of such Convertible Securities,
         plus the minimum aggregate amount of additional consideration, if any,
         payable to the Corporation upon the conversion or exchange thereof, by
         (ii) the total maximum number of shares of Common Stock issuable upon
         the conversion or exchange of all such Convertible Securities) shall be
         less than the Conversion Price in effect immediately prior to the time
         of such issue or sale, then the total maximum number of shares of
         Common Stock issuable upon conversion or exchange of all such
         Convertible Securities shall be deemed to have been issued for such
         price per share as of the date of the issue or sale of such Convertible
         Securities shall be deemed to have been issued for such price per share
         as of the date of the issue or sale of such Convertible Securities and
         thereafter shall be deemed to be outstanding, provided that (a) except
         as otherwise provided in subparagraph 6D(3), no adjustment of the
         Conversion Price shall be made upon the actual issue of such Common
         Stock upon conversion or exchange of such Convertible Securities and
         (b) if any such issue or sale of such Convertible Securities is made
         upon exercise of any options to purchase any such Convertible
         Securities for which adjustments of the Conversion Price have been or
         are to be made pursuant to other provisions of this subparagraph 6D, no
         further adjustment of the Conversion Price shall be made by reason of
         such issue or sale.

                  6D(3) Change in Option Price or Conversion Rate. Upon the
         happening of any of the following events, namely, if the purchase price
         provided for in any Option referred to in subparagraph 6D(1), the
         additional consideration, if any, payable upon the conversion or
         exchange of any Convertible Securities referred to in subparagraph
         6D(1) or 6D(2), or the rate at which Convertible Securities referred to
         in subparagraph 6D(1) or 6D(2) are convertible into or exchangeable of
         Common Stock shall change at any time (including, but not limited to,
         changes under or by reason of provisions designed to protect against
         dilution), the Conversion Price in effect at the time of such event
         shall forthwith be readjusted to the Conversion Price which would have
         been in effect at such time had such Options or Convertible Securities
         still outstanding provided for such changed purchase price, additional
         consideration or conversion rate, as the case may be, at the time
         initially granted, issued or sold, but only if as a result of such
         adjustment the Conversion Price then in effect hereunder is thereby
         reduced; and on the expiration of any such Option or the termination of
         any such right to convert or exchange such Convertible Securities, the
         Conversion Price then in effect hereunder shall forthwith be increased
         to the Conversion Price which would have been in effect at the time of
         such expiration or termination had such Option or Convertible
         Securities, to the extent outstanding immediately prior to such
         expiration or termination, never been issued.

                  6D(4) Stock Dividends. In case the Corporation shall declare a
         dividend or make any other distribution upon any stock of the
         Corporation payable in Common Stock (except for dividends or
         distributions upon the Common Stock), Options or Convertible
         Securities, any Common Stock, Options or Convertible Securities, as the
         case may be, issuable in payment of such dividend or distribution shall
         be deemed to have been issued or sold without consideration.


<PAGE>
                                       -8-


                  6D(5) Consideration for Stock. In case any shares of Common
         Stock, Options or Convertible Securities shall be issued or sold for
         cash, the consideration received therefor shall be deemed to be the
         amount received by the Corporation therefor, without deduction
         therefrom of any expenses incurred or any underwriting commissions or
         concessions paid or allowed by the Corporation in connection therewith.
         In case any shares of Common Stock, Options or Convertible Securities
         shall be issued or sold for a consideration other than cash, the amount
         of the consideration other than cash received by the Corporation shall
         be deemed to be the fair value of such consideration as determined in
         good faith by the Board of Directors of the Corporation, without
         deduction of any expenses incurred or any underwriting commissions or
         concessions paid or allowed by the Corporation in connection therewith.
         In case any Options shall be issued in connection with the issue and
         sale of other securities of the Corporation, together comprising one
         integral transaction in which no specific consideration is allocated to
         such Options by the parties thereto, such Options shall be deemed to
         have been issued for such consideration as determined in good faith by
         the Board of Directors of the Corporation.

                  6D(6) Record Date. In case the Corporation shall take record
         of the holders of its Common Stock for the purpose of entitling them
         (i) to receive a dividend or other distribution payable in Common
         Stock, Options or Convertible Securities or (ii) to subscribe for or
         purchase Common Stock, Options or Convertible Securities, then such
         record date shall be deemed to be the date of the issue or sale of the
         shares of Common Stock deemed to have been issued or sold upon the
         declaration of such dividend or the making of such other distribution
         or the date of the granting of such right of subscription or purchase,
         as the case may be.

                  6D(7) Treasury Shares. The disposition of any shares of Common
         Stock owned or held by or for the account of the Corporation shall be
         considered an issue or sale of Common Stock for the purpose of this
         subparagraph 6D.

         6E. Certain Issues of Common Stock Excepted. Anything herein to the
contrary notwithstanding, the Corporation shall not be required to make any
adjustment of the Conversion Price in the case of the issuance of up to an
aggregate of 500,000 shares (appropriately adjusted to reflect the occurrence of
any event described in subparagraph 6F) of Common Stock to directors, officers
or employees of the Corporation in connection with their service as directors of
the Corporation or their employment by the Corporation.

         6F. Subdivision or Combination of Common Stock. In case the Corporation
shall at any time subdivide (by any stock split, stock dividend or otherwise)
its outstanding shares of Common Stock into a greater number of shares, the
Conversion Price in effect immediately prior to such subdivision shall be
proportionately reduced, and, conversely, in case the outstanding shares of
Common Stock shall be combined into a smaller number of shares, the Conversion
Price in effect immediately prior to such combination shall be proportionately
increased.

         6G. Reorganization or Reclassification. If any capital reorganization
or reclassification of the capital stock of the Corporation shall be effected in
such a way that holders of Common 


<PAGE>
                                       -9-


Stock shall be entitled to receive stock, securities or assets with respect to
or in exchange for Common Stock, then, as a condition of such reorganization or
reclassification, lawful and adequate provisions shall be made whereby each
holder of a share or shares of Series A Convertible Preferred Stock shall
thereupon have the right to receive, upon the basis and upon the terms and
conditions specified herein and in lieu of the shares of Common Stock
immediately theretofore receivable upon the conversion of such share or shares
of Series A Convertible Preferred Stock, such shares of stock, securities or
assets as may be issued or payable with respect to or in exchange for a number
of outstanding shares of such Common Stock equal to the number of shares of such
Common Stock immediately theretofore receivable upon such conversion had such
reorganization or reclassification not taken place, and in any such case
appropriate provisions shall be made with respect to the rights and interests of
such holder to the end that the provisions hereof (including without limitation
provisions hereof (including without limitation provisions for adjustments of
the Conversion price) shall thereafter be applicable, as nearly as may be, in
relation to any shares of stock, securities or assets thereafter deliverable
upon the exercise of such conversion rights.

         6H. Failure to Redeem. If the Corporation fails, for any reason or for
no reason, to redeem on the Redemption Date (as defined in paragraph 7) all of
the then outstanding shares of Series A Convertible Preferred Stock in
accordance with the terms and conditions of paragraph 7, the Conversion Price
then in effect shall be immediately reduced to an amount equal to 90% thereof.
Thereafter, until such redemption has been made in full in accordance with such
terms and conditions, the Conversion Price shall be further reduced on the 90th
day following the Redemption Date and at the end of each 90-day period
thereafter to an amount equal to 90% of the Conversion Price in effect
immediately prior to each such reduction.

         6I. Notice of Adjustment. Upon any adjustment of the Conversion Price,
then and in each such case the Corporation shall give written notice thereof, by
first class mail, postage prepaid, or by telex to non-U.S. residents, addressed
to each holder of shares of Series a Convertible preferred Stock at the address
of such holder as shown on the books of the Corporation, which notice shall
state the Conversion Price resulting from such adjustment, setting forth in
reasonable detail the method upon which such calculation is based.

         6J.  Other Notices.  In case at any time:

                  (1) the Corporation shall declare any dividend upon its Common

any adjustment of the Conversion Price if the total number of shares of Common

the business day next preceding the day on which the Redemption Notice is given)
of shares of Series A convertible Preferred Stock notifying such holder of the
redemption and specifying the Redemption Price, the Redemption date and the
place where said Redemption Price shall be payable. The Redemption Notice shall
be addressed to each holder at his address as shown by the records of the
Corporation. From and after the close of business on the Redemption Date, unless
there shall have been a default in the payment of the Redemption Price, all
rights of holders of shares of Series A Convertible Preferred Stock (except the
right to receive the Redemption Price) shall cease with respect to such shares,
and such shares shall not thereafter be transferred on the books of the
Corporation or be deemed to be outstanding for any purpose whatsoever. If the
funds of the Corporation legally available for the redemption of shares of
Series A Convertible Preferred Stock on the Redemption Date are insufficient to
redeem the total number of outstanding shares of Series A convertible Preferred
Stock, the holders of shares of Series A convertible Preferred Stock shall share
ratably in any funds legally available for redemption of such shares according
to the respective amounts which would be payable with respect to the full number
of shares owned by them if all such outstanding shares were redeemed in full.
The shares of Series A Convertible Preferred Stock not redeemed shall remain
outstanding and entitled to all rights and preferences provided herein. At any
time thereafter when additional funds of the Corporation are legally available
for the redemption of such shares of Series A Convertible Preferred Stock, such
funds will be used, at the end of the next succeeding fiscal quarter, to redeem
the balance of such shares, or such portion thereof for which funds are then
legally available, on the basis set forth above.

            7E. Redeemed or Otherwise Acquired Shares to be Retired. Any shares
of Series A Convertible Preferred Stock redeemed pursuant to this paragraph 7 or
otherwise acquired by the Corporation in any manner whatsoever shall be canceled
and shall not under any circumstances be reissued; and the Corporation may from
time to time take such appropriate corporate action as may be necessary to
reduce accordingly the number of authorized shares of Series A Convertible
Preferred Stock.

         8. Amendments. No provision of these terms of the Series A Convertible
Preferred Stock may be amended, modified or waived without the written consent
or affirmative vote of the holders of at least two-thirds of the then
outstanding shares of Series A Convertible Preferred Stock."

         (4) The foregoing amendment to the Certificate of Incorporation was
authorized by the Board of Directors at a meeting of the Board duly held on
December 12, 1989.

authorization, or filing with any person (including without limitation, any
court, regulatory or administrative agency or governmental authority) is
required in connection with the execution, delivery, performance by, or the

been duly executed and delivered by MSI and constitutes a legal, valid and
binding obligation of MSI, enforceable against it in accordance with its terms,
except to the extent that its enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium and other laws relating to or
affecting creditors' rights generally and by general equity principles.

                3.2.5 The execution, delivery and performance of this Agreement
and the consummation of the transactions contemplated hereby do not and will not
(i) violate any provisions of MSI's Restated Certificate of Incorporation or
By-Laws, or (ii) contravene any law, rule or regulation of any state or the
United States or any political subdivision thereof or therein, or any order,
writ, judgment, injunction, decree, determination or award presently in effect,
or (iii) result in, or require, the creation or imposition of any lien, charge,
encumbrance or claim on any of its properties or revenues pursuant to any
contractual obligation to which MSI is a party or by which any of its assets may
be bound or affected.

                3.2.6 No action, suit, litigation, investigation or proceeding
of or before any arbitrator or governmental authority is pending or (to the best

properties or revenues (i) with respect to this Agreement or any of the

have a material adverse effect on the business, operations, property, prospects
or condition (financial or otherwise) of MSI.

                3.2.7 MSI is not in violation of or default under any provision
of its Restated Certificate of Incorporation or By-Laws or of any contract,
instrument, judgment, order, writ or decree to which it is a party or by which
it is bound or of any provision of any federal or state statute, rule or
regulation applicable to MSI which could be materially adverse to the 


<PAGE>
                                       -7-


business, operations, property, prospects or condition (financial or otherwise)

its obligations under this Agreement and the transactions contemplated hereby.

                3.2.8 At the Closing Date, MSI will be in compliance, in all
material respects, with all material laws, ordinances, governmental rules and
regulations to which it is subject, where the failure to so comply would have a
material adverse effect on the business of MSI or would have an effect on the
enforceability against MSI of this Agreement.

                3.2.9 The offer and sale of the Stock hereunder is exempt from
the registration and prospectus delivery requirements of the Securities Act, and
the rules and regulations thereunder and any other applicable securities laws.

                3.2.10 MSI has heretofore delivered to SHI a copy of its 1986
Annual Report to shareholders and its Annual Report on Form 10-K, both
containing (i) its audited balance sheet as of December 31, 1986, and the
related audited statement of loss, statement of shareholders' equity and
statement of changes in financial position for the fiscal year ended December
31, 1986, accompanied by the report of MSI's independent public accountants
thereon, and (ii) its quarterly report on Form 10-Q containing an unaudited
balance sheet at March 31, 1987, and the related unaudited statement of loss for
the three months ended March 31, 1987. Such financial statements fairly present
the financial position of MSI as of the respective dates thereof and the results
of its operations and (to the extent covered thereby) changes in its financial
position and shareholders' equity for the periods indicated, in accordance with
generally accepted accounting principles in U.S.A., which, except as disclosed
therein, have been consistently applied. Except as disclosed in the financial
statements, including the notes thereto, referred to above, since March 31,
1987, there has not been any material adverse change in the general business
affairs, financial position or results of operations of MSI. MSI has no material
liability or obligation, absolute or contingent.

                3.2.11 This Agreement, representations and warranties by MSI and
any exhibits, schedules, attachments, documents, certificates and other written
items and materials 


<PAGE>
                                       -8-


prepared and supplied to SHI by or on behalf of MSI, with respect to the
transactions contemplated hereby, do not and will not, as the case may be,
contain any untrue statement of a material fact or omit to state any material
fact necessary to make the statements contained therein not misleading in the
context made. There is no fact known to MSI which MSI has not disclosed to SHI
in writing and which is reasonably likely to have a material adverse effect on
the financial condition, operating results, assets or business prospects of MSI
or would have an effect on the enforceability against MSI of this Agreement or
any material contract, agreement or instrument to which MSI is a party.

                3.2.12 Copies of MSI's Restated Certificates of Incorporation
and By-Laws heretofore delivered to SHI are true and correct.

                3.2.13 MSI has all governmental licenses and permits necessary
to conduct its business.

         4. REGISTRATION UNDER THE SECURITIES ACT OF 1933.

            4.1 MSI agrees that prior to any filing by it of a registration
statement under the Securities Act, it will, at least 30 days prior to such
filing, notify SHI of its intention to file such registration statement and,
upon the request of SHI, will include in such registration the shares of Stock
issued to SHI, if, in the opinion of counsel for MSI such registration statement
is required to permit sale of such Stock in the manner contemplated by SHI.

            4.2 Whenever pursuant to Paragraph 4.1 a registration statement
relating to any Stock is filed under the Securities Act, amended or
supplemented, MSI shall indemnify and hold harmless SHI and SHI's officers and
directors (or SHI's assignees if SHI can assign registration rights) and
underwriter for SHI, within the meaning of the Securities Act, who may purchase
from or sell for SHI any shares of Stock from and against any and all losses,
claims, damages and liabilities joint or several caused by any untrue statement

misleading, and MSI will reimburse SHI, each officer, director, underwriter
(within the meaning of the Securities Act) or controlling person for any legal
or other expenses reasonably incurred by them in connection with investigating

as such losses, claims, damages or liabilities are caused by any such untrue
statement or alleged untrue statement or omission or alleged omission based upon
information furnished or required to be furnished in writing to MSI by SHI or
underwriter for SHI expressly for use therein, which indemnification shall
include each person, if any, who controls any such underwriter within the
meaning of such Securities Act; provided, however, that MSI shall not be obliged
so to indemnify SHI or underwriter or controlling person unless SHI or such
underwriter shall at the same time indemnify MSI, its directors, each officer
signing the related registration statement and each person, if any, who controls
MSI within the meaning of such Securities Act, from and against any and all
losses, claims, damages and liabilities caused by any untrue statement or
alleged untrue statement of a material fact contained in any registration
statement or any prospectus required to be filed or furnished by reason of this

to be stated therein or necessary to make the statement therein not misleading,
insofar as such losses, claims, damages or liabilities are caused by any untrue
statement or alleged untrue statement or omission based upon information
furnished in writing to MSI by SHI or underwriter expressly for use therein.

dispose of the Stock, in part or in whole. Any such filing will be at SHI's sole
cost and expense.

Dear Jack,

     As we discussed, I am pleased to inform you that Apple Bank for Savings
has approved a $1,100,000 revolving credit facility and a $1,600,000 term loan.
This approval is subject to the following terms and conditions:

     Loan A - A revolving line of credit in the amount of $1,100,000 secured by
accounts receivable and medical instruments. This line replaces the existing
$1,300,000 line. Advances under the line will be limited to 75% of eligible
accounts receivable. The interest rate on the line will be Apple Bank for 
Savings' Prime plus 2%. The line will expire on April 30, 1992.

     Loan B - A 5 year term loan in the amount of $1,600,000. Proceeds will be
used to refinance two existing term loans at Apple Bank having a total balance 
of approximately $1,000,000 and to repay existing debt under the company's 
revolving line of approximately $600,000. The term loan will be secured by 
medical instruments and the company's accelerator beam. The interest rate to be
charged will be Apple Bank's Prime plus 2%.

     In additional to the above, we expect bank council to prepare a loan 
agreement which will include loan covenants common to this type of transaction.

     I am looking forward to our continued relationship.

                                   Sincerely,

                                   Warran R. Mohr

                                    February 7, 1996



Dr. Kennard H. Morganstern
8 Hunter Lane
Roslyn, NY 11576

Dear Ken:

      The Board of Directors has approved an agreement with you covering the
"Termination Period", as hereinafter defined. The substance of the agreement is
as follows:

      1. You will furnish advice as needed to a Search Committee, consisting of
Kenneth W. Rind, John R. Hoover and Harvey Cohen, which will immediately conduct
a search for a new President. In the event that to acquire a suitable qualified
person as President it is necessary to offer him the position of Chief Executive
Officer as well, you will resign as Chief Executive Officer.

      2. Upon the selection of a new President, you will continue to be Chairman
of the Board and Chief Executive Officer except as hereinbefore stated and will
work with the Board and the new President to ensure a successful transition.

      3. After the new President has been in office for a period of at least one
year, the Board of Directors will determine if he should be continued, and if
so, will elect him Chief Executive Officer if he has not already been so
elected. The determination to retain the new President by the Board will be the
start of the Termination Period.

      4. During the Termination Period, you will continue to serve as Chairman
of the Board, and make yourself available at the option of the new Chief
Executive Officer and provide fifty (50%) percent of your time to perform
similar services to those presently being performed by you.

      5. You will be paid at a base salary equal to fifty (50%) percent of your
salary as of the commencement of the Termination Period for the first year with
a Cost of Living adjustment to said base salary for each of the next two years.
The Cost of Living Increase, if any, shall be computed using as a basis of such
computation the "Consumer Price Index - Urban Wage Earners (1995 = 100)
published by the Bureau of Labor Statistics of the United States Department of
Labor.


<PAGE>

Dr. Kennard H. Morganstern

      6. You will also be entitled to the same benefits provided to other
officers during the Termination Period and for an additional period of two
years, including but not limited to vacation and sick leave, medical and
hospitalization insurance and any 401K Plan or similar plan which might be in
effect during the Termination Period.

            6.1 The group life insurance policy insuring you will be maintained
by MSI during the Termination Period and for an additional period of two years
in the same face amount as may exist at the start of the Termination Period.

      7. As used herein, "Confidential Information" means all technical and
business information of MSI whether or not patentable, which is of a
confidential, trade secret and/or proprietary character and which is or was
either developed by you (alone or with others) or to which you had access during
your employment by MSI. Confidential Information shall include, but shall not be
limited to, names of customers and suppliers, information contained in bids
and/or proposals, contract progress reports and confidential evaluations of, and
the confidential use or non-use by MSI of, technical or business information in
the public domain.

            7.1 During your employment hereunder and thereafter, will not,
directly or indirectly (without MSI's prior written consent), use for yourself
or use for, or disclose to, any party other than MSI, any Confidential
Information for so long as it shall remain proprietary or protectible as
confidential or trade secret information, except as may be necessary for the
performance of your duties for MSI. Each of your obligations in this Paragraph 7
shall also apply to the confidential, trade secret and proprietary information
learned or acquired by you during your employment from others with whom MSI has
a business relationship.

            7.2 At the termination of your employment hereunder or at any other
time MSI may request, you shall promptly deliver to MSI all documents or other
material in your possession relating, directly or indirectly, to Confidential
Information without retaining any copies.

      8. You shall not, directly or indirectly (whether as owner, partner,
consultant, employee or otherwise), at any time during your employment, and the
period of two years following termination for any reason (except for that
termination which would constitute a breach of this Agreement) of your
employment with MSI, engage in or contribute your knowledge to any business
engaged in any work or activity in which MSI is then currently engaged
("Competitive Work") in the Eastern or Midwestern parts of the United States or
other areas where MSI has commenced operations. You agree that this covenant not
to compete is a reasonable covenant under the circumstances, and further agree
that if 


<PAGE>

Dr. Kennard H. Morganstern
February 7, 1995
Page -3-

in the opinion of any Court of competent jurisdiction, such restraint is
not reasonable in any respect, such Court shall have the right, power and
authority to excise such provision or provisions of this covenant as to the
Court shall appear not reasonable and to enforce the remainder of the covenant
as so amended.

            8.1 You shall be permitted to engage in such proposed work or
activity and MSI shall furnish you a written consent to that effect signed by an
officer, if you shall have furnished to MSI clear and convincing written
evidence, including assurances from you and your new employer, that the
fulfillment of your duties in such proposed work or activity would not likely
cause you to disclose, base judgments upon, or use any Confidential Information
(and such consent shall not be unreasonably withheld).

            8.2 Following the expiration of said two year period, you shall
continue to be obligated under the "Confidential Information" section of this
Agreement not to use or to disclose Confidential Information so long as it shall
remain proprietary or protectible as confidential or trade secret information.

            8.3 During your employment by MSI and for a period of two years
thereafter, you shall not, directly or indirectly, induce or attempt to induce a
salaried employee of MSI to accept employment or affiliation involving
Competitive Work with another firm or corporation of which you are or may become
an employee, owner, partner or consultant.

      9. This Agreement shall become effective as of the beginning of the
Termination Period and shall continue thereafter for a period of five (5) years,
unless sooner terminated by reason of your death or as herein otherwise
provided.

            9.1 MSI may terminate this Agreement by written notice delivered to
you at least five (5) days prior to the date of termination, which notice shall
specify the reasons for such termination, upon the commission by you of an act
or series of acts constituting "Cause". For this purpose, "Cause" means (a) an
act of dishonesty by you resulting or intended to result directly or indirectly
in your gain or your personal enrichment or that of your relatives or associates
at MSI's expense, (b) the deliberate and intentional refusal by you (except by
reason of incapacity due to illness or accident) substantially to perform your
duties hereunder, or (c) the willful violation by you of the provisions of
Paragraphs 7 and 8 of this Agreement. No act on your part shall be considered
"willful" unless done by you not in good faith and without reasonable belief
that such act was in the best interest of MSI.

            9.2 If you die, resign, are terminated for "Cause", the Base Salary
and benefits set forth in Paragraphs 5 and 6 above shall be paid through the
date of 

<PAGE>

Dr. Kennard H. Morganstern
February 7, 1995
Page -4-

termination, whereupon MSI shall have no further liability to you under
this Agreement for such payments.

            9.3 If your employment hereunder is terminated by MSI for any reason
other than those specified in subparagraph 9.2.1 above (it being understood that
a purported termination for disability or Cause which is contested by you and
finally determined not to have been proper, shall be treated as a termination
under this subparagraph 9.3), then the Base Salary and benefits set forth in
Paragraphs 5 and 6 above shall be paid throughout the remainder of the five (5)
year term of this Agreement.

      If the foregoing sets forth your understanding of the agreement approved
by the Board of Directors, please sign a copy of this letter under the words
"Agreed To" and return the copy to us.

                                    Very truly yours,

                                    MEDICAL STERILIZATION, INC.

                                AGREEMENT BETWEEN
             PILLING WECK (PW) and MEDICAL STERILIZATION, INC. (MSI)


         Pilling Weck agrees to represent and sell MSI's procedure specific
decontamination, reprocessing and/or sterilization services in selective high
population density urban centers and/or in cooperation with MSI to selective IHN
organizations according to the minimum guidelines in Exhibit A. MSI's current
market development efforts, as outlined in Exhibit B, will be excepted from the
terms of this agreement. MSI grants to Pilling Weck exclusive, except as to MSI,
sales and marketing rights in the United States for the next three years
effective 1/5/96.

[bullet] MSI will continue its current account development efforts in the L.I.
         business Unit Area, but agrees to exclusive third-party representation
         by PW in this area. MSI will train Pilling Weck Sales Representatives
         in the L.I. Business Unit Area (90 mile radius). Pilling Weck will
         receive a commission of new MSI net billings generated by its
         representatives, excepting MSI's current active customer list or
         accounts under active development, as indicated in Exhibit C, within 10
         days after payment receipt from the customer.

                   The commission schedule is as follows:

                  *        New Accounts              [   ]%

                  *        Endoscopy                 [   ]%

         PW agrees that during the first year, [ ]% of the MSI commission
         received and also, [   ]% commission of any MSI purchases of PW 
         instruments will be paid to its representation in the L.I. Business
         Unit Area.

[bullet] Pilling Weck and MSI (The parties are not partners or joint venturers,
         but are independent contractors.) agree to cooperate exclusively to
         commercialize MSI's procedure specific decontamination, reprocessing
         and/or sterilization services throughout North America according to the
         minimum guidelines outlined in Exhibit A. Pilling Weck will use its
         corporate and national account contacts to identify potential customers
         and MSI will support the sales process

                                      -2-

         by making joint presentations with Pilling Weck and coordinating  
         proposals to the clients in a timely basis.

[bullet] MSI agrees to purchase its surgical instrument needs for current and
         future sites from Pilling Weck, and Pilling Weck agrees to supply such
         instruments upon request for the duration of this agreement. Specific
         customer requests or preferences for other brands of instruments,
         however, will be accommodated and excepted from this exclusive
         arrangement. Pricing will be provided at Pilling Weck's possible
         discount level reflected as VP level pricing. MSI has the option to
         purchase such instruments on terms, 60 days from date of invoice or on
         operating lease terms, utilizing PW's third party financing facility,
         or through use of a MSI financing facility. In the event of termination
         of this agreement, PW will not cause termination of any leasing
         arrangement in effect.

[bullet] To start offering an endoscopic set to this trade, Pilling Weck agrees
         to supply MSI with endoscopic sets at this pricing level.

[bullet] Pilling Weck and MSI agree to review options for contribution of
         instruments to new centers, whereby Pilling Weck contributes
         instruments as equity, and receives equity as a percentage of total
         capitalization for that center.

[bullet] Pilling Weck also agrees to review options to supply instruments to
         MSI on a capitated basis, whereby Pilling Weck is paid on a per use
         basis for the instruments and ownership of the instruments remains with
         Pilling Weck.

[bullet] Pilling Weck will provide on-site instrument repair services for MSI,
         as requested by MSI, at VP level pricing at their Syosset, N.Y.
         facility. MSI will provide adequate space to Pilling Weck personnel on
         a rent free basis.

[bullet]   [


                                                                       ].



         The term of this agreement is three years. However, in the event of
change of ownership of the business, either party may cancel this agreement
provided one year's notice is given to the other party. After the first year,
either party, by giving thirty (30) days written notice prior to the end of the
year, may terminate the agreement if new MSI/PW generated contracts of at least
[ ] have not been signed or are pending, or MSI has not purchased or committed
to pending purchases of at least [ ] of PW instruments.

         If Pilling Weck terminates this agreement for reasons other than breach
on MSI's part, Pilling Weck would be bound by an 18 month non-compete in the
geographic areas (180 mile radius) where MSI and Pilling Weck have concluded
contracts.

         The non-compete would cover off-site decontamination, reprocessing, and
sterilization of surgical instruments for hospitals in the specific geographic
area covered.

         If MSI terminates this agreement for reasons other than breach on
Pilling Weck's part, Pilling Weck would be unrestricted in any business
practices and not be bound by the above mentioned non-compete.
