ITEM 1. BUSINESS
 
OVERVIEW
 
  MDT Corporation ("MDT" or the "Company") was organized in 1971 and is
incorporated in Delaware. The Company is a holding company whose principal
operating subsidiaries are MDT Biologic Company, which produces and sells
Sterility Assurance Systems, and MDT Diagnostic Company, which produces and
sells Examining and Operatory Equipment. Effective April 1, 1995, the Company
formed a new operating subsidiary, MDT Technionic Company, which provides
product support, maintenance, repair and other services to customers of MDT
Biologic Company, MDT Diagnostic Company and other manufacturers, and which
also sells to such customers parts and consumable products relating to the
Sterility Assurance Systems and Examining and Operatory Equipment. These
functions were previously performed by the Company's Product Support
Department. The Company also operates international sales and service
subsidiaries, including MDT Asia Limited, MDT Canada Limited and MDT
International Limited. Unless the context otherwise requires, references to
"MDT" and the "Company" include the Company and its subsidiaries.
 
  MDT Biologic Company develops, manufactures and markets Sterility Assurance
Systems, including sterilizers, ultrasonic cleaners, decontaminators, dryers,
scrub sinks and related equipment, accessories and consumables. This equipment
is necessary for cleaning, decontaminating, disinfecting, sterilizing, drying,
aerating, storing and retrieving instruments and other critical items for use
in invasive procedures. Sterility Assurance Systems are used by healthcare
professionals and scientific customers principally to prevent cross-infection
of communicable diseases caused by the use of contaminated instruments or
products.
 
  MDT Diagnostic Company develops, manufactures and markets Examining and
Operatory Equipment for use in diagnostic and therapeutic procedures performed
in hospitals and medical and dental offices, clinics and other non-hospital
treatment facilities. Products include examination, treatment and surgical
tables and lighting systems, dental x-ray machines, dental operatory equipment
(which includes dental chairs, lights and instrument delivery systems) and
other products, together with related accessories and consumables.
 
  MDT Technionic Company (formerly the Product Support Department) services and
otherwise supports the installed base of equipment from both product groups, as
well as the installed base of equipment of other manufacturers.
 
  The Company currently derives approximately 42% and 16% of its revenues from
sales of Sterility Assurance Systems and Examining and Operatory Equipment,
respectively, and approximately 42% of its revenues from the sale of parts,
service and consumables in support of both product groups and, to a much lesser
degree, competitors' products. International sales and service from all product
groups, including the sale of parts, service and consumables, currently account
for approximately 17.8% of the Company's revenues. Financial information can be
found in Items 6, 7 and 8 of this Annual Report.
 
  MDT intends to expand its healthcare products and service business through
the internal development of new products and services complementary to its
current activities. The Company anticipates that such expansion may also take
place, both domestically and internationally, through the acquisition of other
businesses, products and technologies and the development of new manufacturing,
distribution, sales and other strategic relationships with third parties.
 
  Several trends are influencing the need for and use of Sterility Assurance
Systems in the hospital market, including increased utilization of smaller
sterilizers for departmental use to facilitate more rapid turnaround of
expensive instruments and other critical items; aging of the patient
population, with a corresponding increased need for medical care and greater
susceptibility to infection; expanding use of organ replacements and treatment
modalities for patients with cancer, diabetes and other illnesses
 
                                       1
<PAGE>
 
requiring immunosuppressant drug therapies which, by necessity, require more
stringent aseptic practices; and greater use of reusable versus disposable
surgical articles to support healthcare cost containment and to address
concerns about infectious waste.
 
  Other factors are influencing demand for Sterility Assurance Systems in the
dental market. Principally as a result of the use of fluoride in drinking water
by most industrialized countries, the incidence of cavities in their young
adult populations has substantially declined. At the same time, those
populations are living longer and retaining more of their teeth throughout
their lives. Accordingly, while services for the restoration of cavities are
expected to decrease, treatment of periodontal disease, orthodontic procedures,
cosmetic care and other general and specific oral and facial procedures are
expected to increase.
 
  Demand for Sterility Assurance Systems in the hospital, dental and medical
markets is expected to grow over time, due in part to increased professional
awareness and public concern about the risk of cross-infection of virulent
diseases such as AIDS, herpes, hepatitis B and tuberculosis.
 
  According to various market sources, the total number of surgical procedures
performed in all settings (hospitals, surgery centers and medical and dental
offices) has increased from about 22 million in 1985 to just over 29 million in
1994, an increase of approximately 33%. During this period, the proportion of
procedures performed in an outpatient setting has increased from just under 40%
to about 65%. These trends are increasing the utilization of and ultimately the
demand for both Sterility Assurance Systems and Examining and Operatory
Equipment.
 
  A general cautionary note regarding the overall demand for medical equipment
is the growing national concern about the steep rise in the overall cost of
healthcare and its availability, resulting in increasing pressure by
governments, insurers, employers and providers to reduce the growth rates of
healthcare operating and capital costs. The continuing debate on healthcare
reform reflects these and other concerns. Independent of healthcare reform
proposals, healthcare consolidations and alliances are expected to increase
industry efficiencies and strengthen the bargaining position of large providers
of healthcare services. Activities intended to contain the rise in healthcare
costs could continue negatively to impact customer demand for the Company's
products.
 
RECENT COMPANY EVENTS
 
  During fiscal year 1995, the Company announced a series of measures intended
significantly to reduce the Company's costs and expenses and to improve the
effectiveness of its operations, organization and structure. Announced measures
included elimination of jobs and other costs and expenses, consolidation of
offices and facilities (including relocation of the corporate office from
Torrance, California, to Morrisville, North Carolina) and the reorganization of
the Company into three business units effective April 1, 1995.
 
  On June 9, 1995, the Company's wholly owned subsidiary, MDT Diagnostic
Company, sold to Maxxim Medical, Inc. certain inventories, fixed assets and
intangible assets (including the tradename "Bovie") relating to the Bovie line
of electrosurgical products for the sum of $2,600,000 (subject to certain
inventory and related adjustments). MDT Diagnostic Company received a payment
of $1,000,000 upon closing of the transaction. Maxxim Medical, Inc. also
deposited $1,600,000 (representing the balance of the purchase price) into
escrow pending final transfer of fixed assets and inventory in September 1995.
This transaction is expected to result in a pre-tax gain to the Company of
approximately $700,000 during the first quarter of fiscal 1996. The Company
believes that the transaction will enable MDT Diagnostic Company to concentrate
its resources on patient handling equipment, lighting systems and related
accessories.
 
  Also in June 1995, the Company announced that it would market in the U.S. and
Canada operating room systems manufactured by Kreuzer GmbH, of Puchheim,
Germany. The Kreuzer systems, which deliver and control gases, oxygen and power
for anesthesia, diagnostic and monitoring equipment, are
 
                                       2
<PAGE>
 
complementary to and compatible with operating room tables, lights and related
accessories presently manufactured and marketed by the Company. Such systems
will also be installed and serviced by MDT Technionic Company.
 
PRODUCTS
 
  The Company's products are organized into two product groups, Sterility
Assurance Systems and Examining and Operatory Equipment, and the related sale
of parts, service and consumable products. The following table sets forth the
percent of sales attributable to each for the periods indicated:

</TABLE>
 
  Sterility Assurance Systems. MDT is one of the two principal domestic
suppliers of Sterility Assurance Systems and related parts, service and
consumable products. This product group represents the Company's original
business. Sterility Assurance Systems are marketed under the Castle, Harvey and
Wilson brand names, and are comprehensive systems used by the healthcare
professions for cleaning, decontaminating, disinfecting, sterilizing, drying,
aerating, storing and retrieving instruments and other critical items for use
in invasive procedures, and by scientific customers for pharmaceutical,
laboratory, research and bio-tech applications. MDT Biologic Company develops,
manufactures and markets all of the equipment essential to these processes, of
which sterilizers are the primary component.
 
  Castle sterilizers are manufactured in both steam and gas configurations.
Steam sterilizers account for the majority of units sold. These devices utilize
saturated steam to sterilize instruments and other articles through a
combination of heat, moisture and pressure. Gas sterilizers employ ethylene
oxide to eradicate organisms on instruments and other items which cannot
withstand the high temperature, humidity and pressure generated by steam
sterilizers.
 
  Castle steam and gas sterilizers are equipped with microprocessor control
systems and a wide range of additional features and options. These systems
monitor each phase of the sterilization process and control variables to ensure
that conditions for sterilization are met. The systems also allow cycle
programming, provide power outage protection and produce a complete, printed
record of every cycle.
 
  Harvey Chemiclave sterilizers utilize a proprietary chemical formulation,
produced and sold by the Company under the registered name Vapo-Steril, to
produce water-unsaturated vapor when heated in the sterilizing chamber to
eliminate corroding, rusting and dulling of metal instruments. This proprietary
chemical vapor sterilization process is widely used in the dental environment
for sterilizing instruments and handpieces and supplementally used in medical
and hospital environments for processing delicate surgical instruments. Harvey
Hydroclave sterilizers are smaller, portable steam sterilizers used principally
in medical and dental offices and laboratories.
 
  Wilson stainless steel accessory products include utility and instrument
tables and specialty carts, stools, treatment stands and receptacles. The
product line includes an extensive array of products which are used to support
major and minor operating room procedures in an aseptic environment.
 
  Examining and Operatory Equipment. This product group includes devices,
accessories and consumables for use in various diagnostic and therapeutic
procedures performed in hospitals, medical and dental offices, clinics and
other non-hospital treatment facilities. These products are marketed under the
Castle, Shampaine and McKesson brand names. The major product lines are
examination, treatment and surgical tables and lighting systems, dental x-ray
machines and dental chairs, lights and
 
                                       3
<PAGE>
 
instrument delivery systems. In addition, the Company recently entered into an
agreement with Kreuzer GmbH, of Puchheim, Germany, under which the Company will
act as exclusive distributor of Kreuzer operating room systems in the United
States and Canada. See "Business--Recent Company Events."
 
  Parts, Service and Consumable Products. The Company, principally through its
wholly owned subsidiary, MDT Technionic Company, maintains, repairs and
provides replacement parts and consumables for use with both the Company's and
certain competitors' equipment. MDT employs service technicians throughout the
United States and Canada who service Sterility Assurance Systems and Examining
and Operatory Equipment, including electronic controls and electro-mechanical
and mechanical components.
 
  In addition to Vapo-Steril, the proprietary chemical solution used in the
Harvey Chemiclave sterilizer, the Company offers a number of consumable
products for use with Sterility Assurance Systems. Principal among these are
process indicators, including self-sealing indicator bags and biological
monitors which test the sterilizer function and operator technique, detergents
used in washer/sterilizers and decontaminators, cleaning agents used in
ultrasonic cleaners and disposable test packs which provide daily operational
proof of mechanical air removal from high vacuum sterilizers. The Company also
offers a range of accessories and consumables for use with Examining and
Operatory Equipment.
 
  Warranties. The Company generally provides a one-year limited warranty to
end-users on its products, except for power systems and x-ray tube heads, on
which the Company provides a two-year limited warranty, and examination and
treatment tables, which include a three-year limited warranty. The warranties
extend to materials and workmanship and provide for normal exclusions for
improper product use. In the United States and Canada, the warranty for certain
major components is extended for periods ranging from two to fifteen years
conditioned upon normal use, operation and maintenance. The Company maintains a
warranty expense reserve which it believes is adequate to absorb normal charges
at the Company's current level of business.
 
MARKETING
 
  The Company has organized its marketing and sales resources within six
healthcare markets: hospital; medical; dental; governmental; scientific; and
international. In each of these six markets, the Company has utilized common
sales organizations and channels of distribution for both of its product groups
(Sterility Assurance Systems and Examining and Operatory Equipment). MDT,
principally through MDT Technionic Company, also provides parts, service and
consumables for these markets.
 
  The following table sets forth for the periods indicated the approximate
percent of net sales represented by each of these markets:

  Hospital sales are made domestically through MDT sales representatives
directly to hospitals and teaching institutions. A growing portion of such
sales are made under the terms of agreements with hospital groups which are
from one to three years in duration.
 
                                       4
<PAGE>
 
  Medical sales are made domestically through MDT sales representatives to
authorized full-service dealers for physicians, group practices and clinics,
other non-hospital treatment facilities, veterinary care facilities and
laboratories. Medical dealers buy, stock, sell and service MDT products, as
well as competitive products, and receive discounts from the Company's
suggested retail prices.
 
  Dental sales are made domestically through MDT sales representatives to
authorized full-service dealers for dentists, group practices and clinics and
dental laboratories. Dental dealers buy, stock, sell and service MDT products,
as well as competitive products, and receive discounts from the Company's
suggested retail prices.
 
  Governmental sales are made to military facilities and hospitals. The
Company generally sells to these accounts directly, often under competitive
bid arrangements.
 
  Scientific sales are made to various laboratories, biotechnology and
research centers, pharmaceutical firms and other manufacturers. Specifically
designed products, in addition to certain of MDT's hospital, medical and
dental products, are available to this market segment and are generally sold
on a direct basis, often under competitive bid arrangements. In addition, MDT
contracts with several independent sales organizations to serve certain
geographic markets.
 
  International sales (exclusive of Canada) are generally made to contract
distributors who buy, stock, sell and service MDT products. The distributors
are generally exclusive as to such products, and their contracts generally
continue unless terminated by either party with appropriate (minimum 90 days)
notice. In Canada, the Company's sales representatives sell directly to
hospitals and to medical dealers and dental dealers. The Company's principal
export markets are Canada, the Pacific Basin, the Middle East, Mexico and
Latin America and Europe. All international sales are in U.S. dollars, except
in Canada, where sales are denominated in Canadian dollars.
 
  No customer of the Company accounted for more than 10% of consolidated net
sales in fiscal 1995, 1994 or 1993, and no material part of the business is
dependent upon a single customer or a few customers.
 
PRODUCT DEVELOPMENT
 
  MDT expended $4,451,000, $4,692,000 and $4,428,000 on product development in
the three fiscal years ended March 31, 1995, 1994 and 1993, respectively.
Since March 31, 1992, the Company has developed, produced and marketed a
number of new sterility assurance products, including new generations of
Harvey tabletop sterilizers, systems for reducing emissions from ethylene
oxide (EO) sterilizers, a system for using ethylene oxide with non-ozone layer
depleting carbon dioxide (EO/CO/2/) gas mixtures in Castle EO sterilizers, and
a system for reducing water consumption by Castle steam sterilizers.
Additionally, in March 1993, the Company introduced the first of several
specially designed scientific sterilizers. The Company has also introduced
during this same period several new examining and operatory products,
including a battery operated version of Shampaine surgical tables, a Shampaine
surgical table designed to support endoscopic surgical procedures, and a
Shampaine dental chair and Castle dental light.
 
  The Company is in varying stages of planning, developing and testing
additional products and product enhancements to be introduced within the next
18 months. The planned new products and product enhancements involve the
Company's two product groups and include additional models of Harvey tabletop
sterilizers and large Castle sterilizers for scientific use, data collection
enhancements for Castle microprocessor controlled sterilizers, and further
enhancements to Shampaine surgical tables and dental operatory equipment. The
Company also anticipates that additional accessory products and biological,
chemical and other consumable products will be introduced over the next 18
months. These introductions are expected to complement existing product lines.
Certain of these products will be used exclusively with the Company's devices,
while others may also be used with comparable devices of other manufacturers.
 
                                       5
<PAGE>
 
  The Company's research and development program in the field of chemical
sterilization of temperature, moisture and pressure sensitive medical and
dental instruments continued in fiscal 1995, as it will in fiscal 1996. The
Company has acquired an option to purchase certain patents and related rights
covering sterilization of medical and dental instruments and other items by
means of plasma-generated, electrically neutral biocidal species in a field-
free, glowless zone. Such patents are the subject of patent infringement
lawsuits pending in the United States and Canada. See "Business--Product
Liability and Litigation." The Company expects to market a product based on
these patents in 1996, although significant further investment will be required
prior to commercialization.
 
  MDT has, from time to time, expanded its product lines through the
acquisition of businesses, products and technologies. The Company intends to
continue to seek appropriate opportunities to acquire compatible businesses,
products and technologies and to enter into manufacturing, distribution, sales
and other strategic relationships with third parties, both domestically and
internationally.
 
MANUFACTURING
 
  MDT's production facilities utilize numerically controlled and robotic tools
and contain sections for machining, metal fabricating, welding and brazing,
painting and finishing, plating and buffing, assembling, mixing, and inspecting
and testing. Certain of the Company's production facilities also contain
microbiology laboratories.
 
  The Company has alternative sources for most of the materials, parts and
components which it purchases. Certain vendors hold tooling owned by the
Company which is necessary for the production of certain parts and components.
Should one or more of these vendors cease deliveries to the Company for any
reason, production schedules would be disrupted while the Company moved its
tooling to another vendor and deliveries were resumed.
 
BACKLOG
 
  The Company's backlogs at March 31, 1995 and 1994, were approximately $27.1
million and $28.1 million, respectively, of which approximately $21.2 million
and $22.7 million, respectively, were for Sterility Assurance Systems and
approximately $5.9 million and $5.4 million, respectively, were for Examining
and Operatory Equipment. All orders comprising the backlog are firm, written
orders from qualified customers. Approximately 95% of these orders are expected
to be filled in fiscal 1996, with the remainder to be filled in fiscal 1997.
 
COMPETITION
 
  Certain of the Company's competitors have greater financial and other
resources than the Company has. The Company competes in the Sterility Assurance
Systems business primarily with American Sterilizer Company, a subsidiary of
AMSCO International, Inc.; Getinge Inc.; and, in the tabletop sterilizer
market, with Pelton & Crane Company, a subsidiary of Siemens A.G., and several
smaller private companies. Product features, reliability, operating costs,
after-sales service, delivery times and price are the most prevalent
competitive factors with respect to these products.
 
  The Company competes in Examining and Operatory Equipment primarily with
AMSCO International, Inc., Siemens Medical Systems, Inc., a subsidiary of
Siemens A.G., Skytron, a division of Kawasaki Midwest, Inc., and Midmark, Inc.
(examination and surgical tables and lights); Dentsply International (dental x-
ray machines); and Adec Inc., Pelton & Crane Company and other subsidiaries of
Siemens A.G., and several independent companies represented in the United
States by Professional Sales Associates, Inc. (dental chairs, lights and
delivery systems). Product features, reliability, after-sale service, delivery
times and price are the most prevalent competitive factors with respect to
these products.

PATENTS AND TRADEMARKS
 
  The Company actively develops innovative technology and improvements with
respect to its product lines. The Company typically secures patent protection
for significant innovations, and currently holds in excess of 100 unexpired
patents granted by the United States and various foreign countries, ten of
which were issued during the fiscal year ended March 31, 1995. Additional
patent applications are both pending and in preparation. The Company considers
patent rights generally to be of value in terms of its competitive position,
particularly in connection with its sterilizers and related products and
surgical tables and lights.
 
  The Company sells its products under a variety of trademarks, some of which
are considered of sufficient importance to warrant registration in the United
States and various foreign countries in which the Company does business. Among
the Company's registered marks used in connection with Sterility Assurance
Systems are MDT, Castle, Harvey, Chemiclave, Hydroclave, Vibraclean, Vapo-
Steril, Spor-Test, Unispor, Tec-test, Chemitest, Sani-Jet and Wilson.
Registered marks used in connection with Examining and Operatory Equipment
include MDT, Castle, Shampaine, Radi-Op, McKesson, AsepTec, Steri-grip,
Steeltone, Medera, Image and E-Series.
 
GOVERNMENT REGULATION
 
  Most of the Company's current and planned products must be accepted,
registered or licensed prior to sale by the federal Food and Drug
Administration (the "FDA"), the federal Environmental Protection Agency (the
"EPA"), and/or other regulatory authorities, both domestic and foreign. These
authorities also regulate labeling, advertising and other forms of product
marketing claims. Some of the Company's sterilizers and sterilization products
may also be regulated under California's Proposition 65 (the Safe Drinking
Water and Toxic Enforcement Act of 1986). This act prohibits the discharge of
carcinogens and reproductive toxins into sources of drinking water and mandates
that businesses give "clear and reasonable" warnings prior to exposing
individuals to such chemicals. Other pertinent legislation includes the
California Clean Air Act and Birth Defect Prevention Act which are concerned
with the release of substances which may be carcinogenic or reproductive
toxicants into the environment. These acts require the generation of data in
the form of extensive laboratory and animal testing regarding the carcinogenic
and toxic nature of certain of the Company's products and the development of
means to control their release to the environment. Local districts within
California are further empowered to enact legislation which may be even more
stringent than that enacted on a statewide basis.
 
  The Company's Chemiclave sterilizers utilize Vapo-Steril solution as the
sterilizing agent. Vapo-Steril is a chemical formulation which contains a trace
of formaldehyde, a chemical regulated under California's Proposition 65.
Accordingly, Proposition 65 warnings are included in the materials shipped with
Vapo-Steril. Vapo-Steril solution, as a sterilant, is considered a pesticide
and, as such, is registered with the EPA under the Federal Insecticide,
Fungicide and Rodenticide Act ("FIFRA").
 
  Certain of the Company's sterilizers employ ethylene oxide as the sterilizing
agent for certain instruments and other items which cannot withstand the heat,
moisture or pressure common to other types of sterilizers. Use of ethylene
oxide has been the subject of regulatory inquiry on the part of the EPA and
certain state regulatory authorities. Regulatory authorities require control of
emissions of ethylene oxide from such equipment in the work area and may in the
future require reduction of current permissible levels. The Company's ethylene
oxide sterilizers are in compliance with Proposition 65.
 
  The Company's ethylene oxide sterilizers also employ a chlorofluorocarbon,
which is combined with ethylene oxide to form a stable, non-flammable mixture.
Under an international agreement and federal law, production of these
substances will be banned in 1997, in order to protect the stratospheric ozone
layer. Carbon dioxide is a suitable substitute for chlorofluorocarbons. In
addition, major chemical companies have developed other suitable substitutes
for chlorofluorocarbons. The Company provides
 
                                       7
<PAGE>
 
modification kits with which its installed base of ethylene oxide sterilizers
can be retrofitted for use with such alternative mixtures. New ethylene oxide
sterilizers are produced with this capability in order to meet specific
customer requirements.
 
  Under the federal Food, Drug and Cosmetics Act, as amended, the Company is
required to file with the FDA a new device list and to obtain FDA approval for
all new devices which the Company proposes to manufacture and market for use in
the treatment of disease and injury. The procedure for obtaining such approval
differs depending upon the uniqueness of the device, with those devices which
are substantially equivalent to existing devices being eligible for expedited
approval and those devices which represent significant departures from existing
devices requiring pre-marketing approval. In addition, certain claims for some
medical devices cannot be made until the FDA agrees not to object. The devices
are also subject to inspection by the FDA after they receive approval, with
devices which are potentially life-threatening being subject to more stringent
standards. The FDA has established manufacturing standards and record keeping
requirements for manufacturers of medical devices known as "Good Manufacturing
Practices." Each manufacturing facility of the Company must be registered
annually and is subject to recurring, unannounced inspections by the FDA.
 
  The Company must also comply with pressure vessel testing and record keeping
requirements of the American Society of Mechanical Engineers, as required by
applicable laws of various states, and must comply with various requirements
and standards of Underwriters Laboratories, Canadian Standards Association and
other domestic and foreign regulatory agencies.
 
  Although applicable government regulations vary in their provisions, they are
generally stringent and continuing. In addition, regulatory authorities may
exercise their substantial discretion in the application of statutory and
administrative standards in a manner burdensome to the Company. The cost of
compliance with these regulations is difficult to determine, but it is and will
continue to be a significant expense for the Company. The Company believes that
it has obtained, has applied for, or is in the process of applying for, all
material regulatory approvals applicable to its existing products, facilities
and processes.
 
PRODUCT LIABILITY AND LITIGATION
 
  The nature of the products of the Company, notably ethylene oxide sterilizers
and electrosurgery devices, has, from time to time, resulted in product
liability claims. To date, such claims have been covered by insurance policies,
except for self-insured retentions. MDT intends to continue to be covered by
product liability insurance. The Company's product liability insurance is
generally subject to self-insured retentions of $100,000 per occurrence and
$500,000 annually in the aggregate.
 
  The Company did not produce ethylene oxide sterilizers prior to the
acquisition of Castle Company ("Castle") from Sybron Corporation ("Sybron") on
July 2, 1987. As part of that transaction, Sybron agreed to retain
responsibility for Castle-related product liability claims pending or
threatened as of July 2, 1987, subject to the Company's assumption of liability
in the aggregate up to $1.1 million in connection with such specified claims (a
reserve for which was established by the Company in such amount). The Company
has satisfied its obligation under the agreement.
 
  The Company has been informed that certain of Sybron's excess liability
insurance carriers may not be financially able to pay judgments resulting from
product liability claims relating to incidents occurring prior to January 1,
1986. With respect to any judgments against the Company which exceed the amount
of Sybron's primary insurance coverage, the Company may be responsible for that
portion of a judgment which any excess liability insurance carrier is unable to
pay.
 
  Ethylene oxide product liability cases filed since July 2, 1987, against the
Company by an aggregate of 25 plaintiffs are currently pending in the Illinois
State Circuit Court of Cook County, Law Division, and the Texas State District
Court of Anderson County, Third Judicial District, respectively. The Company's
expenses and any potential judgments in these actions would be covered by the
Company's product
 
                                       8
<PAGE>
 
liability insurance (up to the limits of such coverage), except for self-
insured retentions and punitive damages, if any. The Company believes that the
allegations in all of these cases are without merit, and the Company and its
insurer intend vigorously to defend these actions.
 
  In February 1994, the Company filed a lawsuit against AbTox, Inc., a
privately held company, charging AbTox with infringing patents which MDT has an
option to purchase from the inventor and his controlled corporation (jointly
referred to as "Exitron"). The patents define a technology utilizing plasma-
generated neutral species in a sterilizer intended to replace ethylene oxide
gas sterilizers and other low temperature alternatives to autoclaves. MDT
initially filed suit in the U.S. District Court in the Central District of
California seeking to enforce the Exitron patents and to restrain AbTox from
the production and sale of a product which allegedly infringes the Exitron
patents. In March 1994, AbTox filed substantially identical suits against MDT
and Exitron in U.S. District Courts in Chicago, Illinois and Boston,
Massachusetts, respectively, seeking to invalidate the Exitron patents and
assert an AbTox patent against a plasma sterilization device initially
developed by Exitron and now undergoing additional testing and development by
MDT.
 
  MDT has withdrawn its original complaint and has filed a corresponding
complaint as an intervenor in the suit in Boston, Massachusetts. In November
1994, the suit in Illinois was transferred to Boston and all suits pending were
subsequently consolidated in a single suit in Boston with the parties being
AbTox, Exitron and MDT. In December, 1994, suit was filed by MDT in Canada
against AbTox for patent infringement. MDT intends vigorously to pursue its
claims and to oppose the AbTox claims.
 
EMPLOYEES
 
  At March 31, 1995, MDT employed 1,102 persons full-time in the following
areas: manufacturing, engineering and quality assurance (526); marketing and
sales (153); product support (304); administration (65); and research,
development and compliance (54). The Company believes that its overall
relations with its employees are good.
 
  Production employees at the Henrietta, New York, manufacturing and
engineering facility are represented by the International Association of
Machinists and Aerospace Workers (AFL-CIO) (the "IAM") and the Metal Polishers,
Buffers, Platers and Allied Workers International Union (AFL-CIO) (the
"Polishers, Buffers and Platers") under three-year contracts which expire April
1, 1997.
 
  The collective bargaining agreements with the unions cover wages, hours and
conditions of employment, as well as health, life and accident insurance and
retirement plans. The Company maintains a pension plan providing retirement and
certain disability benefits to union employees based on years of service.
Retirement age under this plan is 65, with reduced benefits available to
persons who retire between ages 55 and 65 and who meet certain other
conditions. Benefits under the plan are fully vested after seven years of
service. These benefits are comparable to those provided to nonunion employees.
 
  The Company maintains the MDT Corporation Savings and Thrift Plan for Hourly
Employees covering its nonunion hourly employees and the MDT Biologic Company
Union Thrift Plan covering its union employees. These plans are similar to the
MDT Corporation Savings and Thrift Plan for Salaried Employees.
 
ITEM 2. PROPERTIES
 
  The Company owns approximately 32.5 acres of land and related buildings and
improvements in Henrietta, New York, which house the headquarters and certain
operations for two of its operating subsidiaries, MDT Biologic Company and MDT
Technionic Company, as well as certain corporate activities. The Company owns
approximately three acres of land and a manufacturing and engineering facility
in Rancho Dominguez, California, which is utilized by MDT Biologic Company. The
Company
 
                                       9
<PAGE>
 
acquired on August 31, 1992, as part of its acquisition of Consolidated
Equipment Supply Corporation, approximately 2.5 acres of land and a
manufacturing and engineering facility in Mercersburg, Pennsylvania, which is
also utilized by MDT Biologic Company. The Mercersburg property secures two
loans with an aggregate outstanding principal balance of $278,000 as of March
31, 1995. See Note 9 of Notes to Consolidated Financial Statements. None of the
Company's other owned properties is held subject to any major encumbrance.
 
  The Company occupies four leased facilities in North Charleston, South
Carolina, three under co-terminus leases. These facilities house the Company's
third operating subsidiary, MDT Diagnostic Company, and a service center for
MDT Technionic Company. The Company has purchased 15 acres of land in
Summerville, South Carolina (adjacent to North Charleston), on which it intends
to construct a new facility within which it will consolidate the operations of
MDT Diagnostic Company and an MDT Technionic Company service center.
Construction of the new facility is anticipated to begin in the second half of
fiscal 1996 or the first half of fiscal 1997. The Company intends to finance
the new facility with industrial revenue bonds.
 
  The Company occupies its corporate headquarters in Torrance, California under
the terms of a lease which expires on June 30, 1995. The Company is presently
relocating its corporate headquarters to a new leased facility in Morrsville,
North Carolina. Such relocation is expected to be completed in July 1995. The
Company also leases sales and service offices in Anaheim, California; Norcross,
Georgia; Lombard, Illinois; Arnold, Maryland; Athens, Greece; and Hong Kong.
Warehouse facilities as well as sales and service offices are leased in Plano,
Texas, and Toronto, Ontario, and Montreal, Quebec, Canada. The Company also
maintains a liaison office in New Delhi, India. As part of its reorganization,
the Company will close in June 1995 the Plano, Texas, warehouse facilities and
sales and service offices, as well as downsize the other domestic sales and
service offices as their respective leases expire.
 
  The following table sets forth certain information concerning the principal
manufacturing and engineering facilities of the Company and its subsidiaries.
The table excludes the leased corporate facility in Morrisville, North
Carolina, and leased sales and service offices and warehouse facilities
throughout the United States and Canada and in Athens, Greece, and Hong Kong,
totaling approximately 36,000 square feet.

FISCAL YEAR ENDED MARCH 31, 1995, AS COMPARED TO FISCAL YEAR ENDED MARCH 31,
1994
 
  Sales for the fiscal year ended March 31, 1995, of $135,462,000 were
$1,013,000 below sales for fiscal year 1994, a decrease of 0.7%. Sales of
parts, service and consumables were up 10.8% for the recent year compared to
the prior year while sales of sterility equipment were down 5.9% and sales of
Examining and Operatory Equipment were down 6.9% for the recent year compared
to the prior year. Lower equipment sales resulted from continuing buyer
uncertainty in the domestic healthcare markets related to healthcare reform and
from continuing industry consolidation and retrenchment. Higher sales of parts,
service and consumables reflect customer resolve to extend the life of existing
equipment in the current environment.
 
  Incoming orders of $134,535,000 for the recent year were essentially the same
when compared to incoming orders of $134,403,000 in the prior year. Stronger
orders in the international, scientific and service markets were offset by
weaker orders in the domestic healthcare markets. Backlog was $27,145,000 at
March 31, 1995, compared to $28,072,000 a year earlier.
 
  Gross profit of $42,898,000 was $849,000, or 1.9%, lower in fiscal 1995
compared to fiscal 1994, while gross profit as a percentage of sales was 31.7%
in the current year versus 32.1% in the prior year. Current year gross profit
and gross profit margin were reduced by $371,000 as the result of a strike at
the Company's Henrietta, New York, plant in April 1994. The decrease from the
prior year (excluding the effect of the strike) was primarily due to the
combined effects of lower sales, higher manufacturing costs resulting from
reduced production levels, somewhat lower pricing overall, temporary
manufacturing inefficiencies associated with the consolidation in December 1994
of the former Elkhorn, Wisconsin, operation with the North Charleston, South
Carolina, operation and the comparative impact of implementing the LIFO method
for costing substantially all inventories in fiscal 1995. These negative
impacts were partially offset by cost reductions implemented during the fiscal
year, the favorable gross profit impact of which was first realized during the
fourth quarter of fiscal year 1995.
 
  Effective April 1, 1994, the Company implemented the LIFO method for costing
substantially all of its inventories. In fiscal 1994, approximately 44% of the
Company's consolidated inventories was valued using the LIFO method, with the
balance valued using the FIFO method. During fiscal 1995, the Company recorded
incremental LIFO reserves of $656,000 as a result of this change.
 
  Operating expenses of $37,355,000 decreased $1,276,000, or 3.3%, in fiscal
1995 compared to fiscal 1994. The reduction in operating expenses reflects the
implementation of cost reductions during the fiscal year, offset in part by
patent litigation costs and new product introduction costs. Overall, operating
expenses as a percentage of sales decreased to 27.6% in fiscal 1995 from 28.3%
in fiscal 1994.
 
  Reorganization costs, reflecting employee severance payments, lease
termination costs and recruitment and relocation costs, totaling $1,235,000
were recorded in fiscal 1995. These costs are associated with the Company's
efforts to lower its break-even point in the face of current market
uncertainties while at the same time improve the effectiveness of its
operations, organization and structure. Announced measures are intended to
reduce costs in excess of $4,000,000 on an annualized basis from what they
would otherwise have been. The fiscal 1995 cost associated with each of the
measures is: elimination of jobs and other costs and expenses, $733,000;
consolidation of sales and service offices including centralization of service
dispatch and parts and service order entry, $215,000; and reorganization of the
Company into three business units, including the relocation of the Corporate
Office from Torrance, California, to Morrisville, North Carolina, $287,000.
Reorganization costs remaining to be incurred and expensed in fiscal 1996 are
expected to approximate $700,000.
 
  Operating income of $4,308,000 was $808,000, or 15.8%, lower in fiscal 1995
than in fiscal 1994, reflecting lower gross profit and reorganization costs
partially offset by lower operating expenses.
 
                                       15
<PAGE>
 
  Interest expense increased $711,000 in fiscal 1995 to $3,514,000. The
increase was due primarily to increases in the prime rate, to which most of the
Company's debt is related.
 
  The effective income tax rate increased to approximately 59% in fiscal 1995
compared to 42% in fiscal 1994. The increase in the effective tax rate
primarily reflects the impact on the percentage rate calculation of permanent
book-to-tax differences stemming from the 50% limitation on the deductibility
of travel related expenses applied to reduced taxable income after
reorganization costs.
 
  Income before cumulative effect of change in accounting method of $276,000,
or $.04 per share, in the current year, compares to $1,243,000, or $.18 per
share, in the prior year, a decrease of $967,000, or 77.8%, reflecting the
factors previously discussed.
 
  During fiscal 1994, the Company recorded the effect of a change in accounting
method for applying overhead costs to inventory, which resulted in a cumulative
write-up of inventories of $699,000, net of tax, or $.11 per share. (See Note 2
to the Notes to Consolidated Financial Statements.)
 
  Net Income of $276,000, or $.04 per share, for fiscal 1995, compared to
$1,942,000, or $.29 per share, for fiscal 1994, a decrease of 85.8%.
Reorganization costs of $1,235,000, costs related to a strike in April 1994 of
$371,000 and incremental LIFO reserves of $656,000, taken together with the tax
effect discussed above, reduced net income by $1,312,000, or $.19 per share, in
fiscal 1995.
 
FISCAL YEAR ENDED MARCH 31, 1994, AS COMPARED TO FISCAL YEAR ENDED MARCH 31,
1993
 
  Sales for the fiscal year ended March 31, 1994, of $136,475,000 were
$2,528,000 above sales for fiscal year 1993, an increase of 1.9%. Higher sales
reflect increased demand for parts, service and consumables, higher shipments
of washing and decontamination equipment and incremental shipments of
"Hamilton" examination and treatment tables acquired in December 1993, which,
taken together, aggregate an increase of 6.3%, partially offset by lower
shipments of sterilization equipment, both domestically and in Canada, which
aggregated 4.4%. Shipments of Examining and Operatory Equipment were
essentially flat when compared to the prior fiscal year.
 
  Incoming orders of $134,403,000 for the fiscal year were essentially flat
when compared to incoming orders in the prior fiscal year of $135,252,000. For
fiscal year 1994, incoming orders reflected similar product and market
patterns, as did sales. The Company has noted that outstanding bid proposals
are at historically high levels, in part due to the Company's entry into the
scientific market. However, uncertainty surrounding pending healthcare reform
slowed the pace of conversion of bid proposals to purchase orders which
resulted in softer demand for hospital equipment. Pricing was more competitive
during the fiscal year, with greater competitiveness noted in the scientific
market where the Company was a recent market entrant. Backlog was $28,072,000
at March 31, 1994, compared to a backlog of $29,505,000 a year earlier.
 
  Gross profit of $43,747,000 was $527,000, or 1.2%, lower in fiscal 1994
compared to fiscal 1993, while gross profit as a percentage of sales was 32.1%
in fiscal 1994 versus 33.1% in fiscal 1993. The lower gross profit and gross
profit margin reflect the unfavorable impact on the Company of lower sales
volume of hospital sterilization equipment and greater price competitiveness,
combined with the write-off of partially remanufactured sterilizers. These
factors more than offset the favorable impact of higher sales of parts, service
and consumables and washing and decontamination equipment.
 
  Operating expenses of $38,631,000 were $1,382,000, or 3.7%, higher in fiscal
1994 than were operating expenses in the prior fiscal year. Sales and marketing
expense increased by $1,082,000, or 4.6%, reflecting higher expense for
advertising, trade shows and product promotion, including launch of APECS
scientific sterilizers. Administrative expense increased $36,000, or 0.4%,
reflecting higher professional fees offset by reduced provisions for incentive
compensation. Product development expense increased $264,000, or 6.0%,
reflecting a somewhat higher level of product development activity. Overall,
operating expenses as a percentage of sales increased to 28.3% in fiscal 1994,
from 27.8% in the prior fiscal year.
 
                                       16
<PAGE>
 
  Operating income of $5,116,000 was $1,909,000, or 27.2%, lower in fiscal 1994
than in the prior fiscal year, reflecting lower gross profit and higher
operating expense.
 
  Interest expense increased $47,000 in fiscal year 1994, to $2,803,000. The
increase reflects higher levels of borrowing offset in part by lower interest
rates. Additional borrowing was required to finance the purchase of the
Hamilton line of examination tables and to support higher levels of inventory.
 
  The effective income tax rate was essentially unchanged at 42.0% in fiscal
year 1994, as compared to 41.9% in fiscal year 1993.
 
  Effective April 1, 1993, the Company recorded a change in accounting method
which resulted in a cumulative write-up of inventories of $699,000 ($1,206,000
before taxes) to adopt the full-absorption method of accounting for
inventories, which method allocates manufacturing overhead to production
materials as well as to production labor. (See Note 2 of the Notes to
Consolidated Financial Statements.)
 
  Net income of $1,942,000, or $.29 per share, for fiscal 1994, compared to
$2,376,000, or $.38 per share in fiscal 1993, a decrease of 18.3%, reflecting
the aforementioned factors.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  At March 31, 1995, the Company's current ratio was 1.5 to 1 and working
capital was $23,427,000. This compares to a current ratio of 1.6 to 1 and
working capital of $26,636,000 at March 31, 1994. The changes in current ratio
and working capital reflect a $2,983,000 decrease in inventory. The decrease in
inventory was principally the result of the Company's inventory reduction
program, whereby lower production schedules were initiated in July 1994. Normal
production schedules were resumed at each of the Company's manufacturing
facilities during the fourth quarter of fiscal 1995. The Company expects to
continue efforts to reduce inventory in fiscal 1996. Additionally, the current
ratio and working capital reflect a $1,000,000 increase in notes payable and a
$680,000 increase in accounts payable. The aforementioned factors were
primarily offset by an increase in cash of $1,107,000 and an increase in
receivables of $1,510,000. The increase in receivables is primarily attributed
to higher fourth quarter sales. At March 31, 1995, Stockholders' Equity per
share was $6.72 compared to $6.68 at March 31, 1994.
 
  During fiscal 1995, net cash provided by operating activities of $6,440,000
reflected the aforementioned decrease in inventories and increase in accounts
payable and accrual liabilities partially offset by increases in receivables
and other assets. Net cash provided by operating activities was offset by
capital expenditures of $3,067,000, including $1,217,000 for new roofs for the
Company's Henrietta, New York, facilities, and payments on long-term debt of
$3,429,000, which, taken together, resulted in borrowings of $1,000,000 under
the Company's revolving line of credit and an increase in cash balances of
$1,107,000.
 
  The Company has announced a series of measures intended to lower its break-
even point in the face of current market uncertainties, primarily associated
with healthcare reform, while at the same time improve the effectiveness of its
operations, organization and structure. Announced measures include elimination
of jobs and other costs and expenses, consolidation of sales and service
offices, including centralization of service dispatch and parts and service
order entry, and reorganization of the Company into three business units,
including the relocation of the Corporate Office from Torrance, California, to
Morrisville, North Carolina. These measures are intended to reduce costs in
excess of $4,000,000 on an annualized basis from what they would otherwise have
been. Through March 31, 1995, the Company has incurred $1,235,000 in
reorganization costs related to these measures. Reorganization costs remaining
to be incurred and expensed in fiscal 1996 are expected to approximate
$700,000.
 
 
                                       17

  In December 1994, the Company consolidated its former Elkhorn, Wisconsin,
operation with its North Charleston, South Carolina, operation. The
consolidation is expected to lower overhead costs by approximately $550,000 on
an annualized basis once the operations are fully integrated.
 
  The Company is directing a significant portion of its research and
development efforts to the development of technology utilizing plasma generated
neutral species in a sterilizer intended to replace ethylene oxide gas
sterilizers and other low temperature alternatives to autoclaves. The Company
expects to introduce a commercial product utilizing the technology sometime in
1996. A significant portion of the technology is embedded in patents which MDT
has an option to purchase from the inventor and his controlled corporation
(jointly referred to as "Exitron"). Development costs are expensed as incurred.
The Company has capitalized $780,000 related to the purchase of the technology
from Exitron together with related patent and other asset costs. MDT has filed
lawsuits against AbTox, Inc., Mundelein, Illinois, in both the United States
and Canada seeking to prove infringement of the patents, obtain monetary
damages, and restrain AbTox from the sale of a product which MDT believes
infringes the patents. AbTox has filed counter claims against MDT and Exitron.
In fiscal 1995, MDT spent $469,000 on legal and professional fees related to
this matter. MDT expects to expend further amounts in fiscal 1996 to
commercialize the technology and to protect its patent position.
 
  The Company made capital expenditures of $3,067,000 in fiscal 1995 compared
to $2,989,000 in fiscal 1994. Capital expenditures are anticipated to total
approximately $2,500,000 in fiscal 1996, for production machinery and
equipment, tooling and molds. Total committed capital expenditures were
approximately $1,333,000 as of March 31, 1995. The Company owns fifteen acres
of land in Summerville, South Carolina (adjacent to North Charleston), on which
it intends to construct and occupy a new manufacturing and engineering facility
and within which operations currently located in four leased facilities in
North Charleston will be consolidated. Construction of the new facility has
been delayed but is expected to begin in the second half of fiscal 1996 or in
the first half of fiscal 1997. The Company estimates that the cost of
construction when complete will approximate $6,000,000 and intends to finance
the new facility with industrial revenue bonds.
 
  On June 9, 1995, the Company's wholly owned subsidiary, MDT Diagnostic
Company, sold to Maxxim Medical, Inc. certain inventories, fixed assets and
intangible assets (including the tradename "Bovie") relating to the Bovie line
of electrosurgical products for the sum of $2,600,000 (subject to certain
inventory and related adjustments). MDT Diagnostic Company received a payment
of $1,000,000 upon closing of the transaction. Maxxim Medical, Inc. also
deposited $1,600,000 (representing the balance of the purchase price) into
escrow pending final transfer of fixed assets and inventory in September 1995.
This transaction is expected to result in a pre-tax gain to the Company of
approximately $700,000 during the first quarter of fiscal 1996.
 
  The Company finances its working capital with a $30,000,000 revolving line of
credit with two commercial banks. The line is to be repaid in full with all
accrued interest on August 1, 1995, unless renewed. The Company expects to
renew and expand the line prior to August 1, 1995. At March 31, 1995, the
outstanding principal balance on the revolving line of credit was $25,600,000.
(See Note 8 of the Notes to Consolidated Financial Statements.) Management
believes that net cash provided by operating activities in conjunction with the
Company's credit resources will be sufficient to meet its cash needs for the
next 12 months.
 
  Healthcare reform, both in the public and private sector, has resulted in
customer uncertainty, flattened sales and pricing pressures. Independent of
healthcare reform proposals, healthcare consolidations and alliances are
expected to increase industry efficiencies and strengthen the bargaining
position of large providers of healthcare services. Activities intended to
contain the rise in healthcare costs could have a negative impact on the
Company. However, management anticipates that ultimately certain other longer-
term trends in the healthcare industry will contribute to further growth
 
                                       18
<PAGE>
 
in demand for the Company's products and services. These trends include
increasing awareness and concern regarding the transmission of infectious
diseases, an aging United States population requiring additional levels of
healthcare, expanded use of certain treatments requiring stricter aseptic
practices, an increasing number and variety of surgical procedures and greater
use of reusable, rather than disposable, surgical articles to support
healthcare cost containment.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
 
                          INDEPENDENT AUDITORS' REPORT
 
The Stockholders and Board of Directors
MDT Corporation:
 
  We have audited the accompanying consolidated balance sheets of MDT
Corporation and subsidiaries as of March 31, 1995 and 1994 and the related
consolidated statements of income, stockholders' equity and cash flows for each
of the years in the three-year period ended March 31, 1995. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of MDT
Corporation and subsidiaries as of March 31, 1995 and 1994 and the results of
their operations and their cash flows for each of the years in the three-year
period ended March 31, 1995, in conformity with generally accepted accounting
principles.
 
  As discussed in note 2 to the consolidated financial statements, in 1994 the
Company changed its method of accounting for inventories.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                            MARCH 31, 1995 AND 1994
 
(1) BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Business
 
  The Company develops, manufactures, markets and services sterility assurance
systems, examining and operatory equipment and associated accessories and
consumables. These products and services are marketed both domestically and
internationally to hospitals, medical and dental practitioners, and
governmental, institutional and scientific organizations. The Company has
organized its marketing and sales resources to serve these markets.
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of MDT Corporation
and its wholly owned subsidiaries (the Company). All significant intercompany
balances and transactions have been eliminated in consolidation.
 
 Cash and Cash Equivalents
 
  The Company considers all highly liquid debt instruments with a maturity of
three months or less to be cash equivalents.
 
 Inventories
 
  Inventories are valued at the lower of cost or market (see note 2). In fiscal
1995, the cost of substantially all of the Company's inventories is determined
using the last-in, first-out (LIFO) method. In fiscal 1994, the cost of
inventories was determined using both the LIFO and the first-in, first-out
(FIFO) methods.
 
 Property, Plant and Equipment
 
  Property, plant and equipment is carried at cost. Depreciation and
amortization is computed using the straight-line method over the estimated
useful lives of the assets. Expenditures for maintenance and repairs are
charged to expense and renewals and improvements are capitalized.
 
 Other Assets
 
  Other assets, consisting primarily of patents, trademarks, noncompete,
consulting and licensing agreements, are being amortized using the straight-
line method over the shorter of their legal or estimated useful lives.
 
 Product Warranties
 
  The Company sells its products generally with warranties ranging from one to
two years. The estimated cost of repairs under existing warranties has been
provided for in the consolidated financial statements.
 
 Revenue Recognition
 
  Product sales are recognized when title passes, generally at the time
products are shipped. Service sales are recognized ratably over the relevant
contractual period or as the service is performed, as appropriate. Service fees
received but unearned are included in the consolidated balance sheets as
deferred income.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                            MARCH 31, 1995 AND 1994
 
 Earnings per Share
 
  Earnings per share are based upon weighted average common and common
equivalent shares outstanding, amounting to 6,775,000, 6,781,000 and 6,293,000
shares for each of the three years ended March 31, 1995, 1994 and 1993,
respectively. Fully diluted earnings per share is not shown since the
calculation is antidilutive.
 
 Income Taxes
 
  In February 1992, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 109, "Accounting for Income Taxes"
(Statement 109). Statement 109 requires a change from the deferred method of
accounting for income taxes under APB Opinion 11 to the asset and liability
method of accounting for income taxes. Under the asset and liability method of
Statement 109, deferred tax assets and liabilities are recognized for the
estimated future tax consequences attributable to differences between the
financial statement carrying amounts of existing assets and liabilities and
their respective tax bases. Deferred tax assets and liabilities are measured
using enacted tax rates in effect for the year in which those temporary
differences are expected to be recovered or settled. Under Statement 109, the
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in the period which includes the enactment date.
 
  The Company adopted Statement 109 in the fiscal year ended March 31, 1994 and
as allowed in Statement 109 has applied the provisions of Statement 109
retroactively to April 1, 1988. Accordingly, all periods prior to March 31,
1994 have been restated.
 
(2) ACCOUNTING CHANGE
 
  Effective April 1, 1993, the Company changed its method of applying overhead
costs to inventory. Overhead costs attributable to the handling and storage of
inventory are based upon the material component of inventory while other
overhead costs are applied based upon direct labor dollars. Previously, all
overhead costs were allocated to inventory based upon labor dollars. The
Company believes that this change is preferable because it more accurately
matches costs related with revenues. The cumulative effect of this change on
prior years, reported as an increase in net earnings for the year ended March
31, 1994, was $699,000 (net of $507,000 of income taxes) or $.11 a share.
 
  The effect of the change on fiscal 1994 earnings was to decrease income
before cumulative effect of change in accounting principles by $81,000 ($.01
per share). Quarterly results for fiscal 1994 have been restated in note 16 to
these consolidated financial statements to reflect the retroactive application
of this change after a reduction for related income taxes.
 
(3) REORGANIZATION COSTS
 
  During fiscal 1995, plans were developed with the intention of significantly
reducing the Company's cost structure and improving the effectiveness of its
operations, organization and structure.
 
  The restructuring program involves the reduction of 70 employees,
consolidations of offices and facilities (including the relocation of the
Corporate office from Torrance, California to Morrisville, North Carolina) and
the reorganization of the Company into three business units.
 
  The March 31, 1995 consolidated statement of income includes $1,235,000 of
pre-tax charges related to the aforementioned employee terminations, facility
closures and relocation expenses. At March 31, 1995, $240,000 of this amount,
relating to severance and lease termination costs, remained in accrued
liabilities.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                            MARCH 31, 1995 AND 1994
 
  It is estimated that an additional $700,000 will be incurred and expensed in
fiscal 1996 to complete the plan.
 
(4) ACQUISITIONS
 
  In fiscal year 1992, the Company acquired certain assets (principally
inventories and specified fixed assets) from the equipment division of Smith &
Nephew, Inc., a manufacturer of operating room tables and other hospital
equipment, for certain consideration including a convertible note payable to
the seller of $3,000,000. The acquisition was accounted for as a purchase.
 
  During fiscal year 1994, Smith & Nephew, Inc. converted the $3,000,000 note
to 442,477 shares of common stock at $6.78 per share.
 
  In connection with the conversion, the tax basis of the Company's investment
in the underlying assets was increased, resulting in additional deductible
amounts for Federal and state tax purposes. In fiscal year 1994, approximately
$476,000 was deductible for Federal and state tax purposes. The tax effect of
this basis difference was reflected as an addition to additional paid-in
capital in the consolidated statements of stockholders' equity.
 
  On August 31, 1992, the Company acquired the Consolidated Equipment Supply
Corporation (CESCO), a manufacturer of cleaning and decontaminating equipment,
for $2,500,000 in cash and a note payable of $2,500,000 in exchange for all of
the outstanding shares of CESCO stock and related noncompetition and consulting
agreements. Approximately $703,000 of the purchased assets were immediately
converted to cash. The acquisition was accounted for as a purchase;
accordingly, the acquired assets and liabilities were recorded at estimated
fair values at the date of acquisition.
 
  On December 1, 1993, the Company acquired the Hamilton line (principally
inventories, fixed assets and intangibles) of examination tables from Mesa
Industries Inc. for $2,400,000 in cash and a $399,000 promissory note. The
acquisition was accounted for as a purchase; accordingly, the acquired assets
and liabilities were recorded at estimated fair market values at the date of
acquisition.
 
(5) INVENTORIES
 
  Inventories at March 31, 1995 and 1994 consist of the following:

                                                         =========== ===========
</TABLE>
 
  Certain inventories are valued using the LIFO method and comprise
approximately 97% and 44% of consolidated inventories at March 31, 1995 and
1994, respectively. As a result of this increase, incremental LIFO reserves of
$656,000 were recorded in fiscal 1995. Inventories valued using the LIFO method
would be $2,716,000 and $2,130,000 greater at March 31, 1995 and 1994,
respectively, using the FIFO method. The book value of LIFO inventories differs
from the underlying tax basis due to an acquisition made by the Company in July
1987. At March 31, 1995 and 1994, LIFO inventories for book purposes exceeded
those for tax purposes by $8,170,000 and $8,860,000, respectively.

(8) NOTES PAYABLE
 
  The Company has a secured line of credit with two commercial banks which
provides for advances up to $30,000,000 at .25% above the banks' prime rate of
interest (aggregate of 9.25% at March 31, 1995). In addition, the Company pays
a quarterly commitment fee of .25% per annum on the average unused amount. The

line is secured by inventories, accounts receivable, equipment and intangible
assets. The Company is currently negotiating a renewal of a similar line of
credit agreement with its lenders.

(10) COMMITMENTS AND CONTINGENT LIABILITIES
 
 Operating Leases
 
  The Company occupies manufacturing, warehousing and office facilities under
terms of operating leases which expire at various dates through August 2001.
The annual minimum lease payments thereunder for the years subsequent to March
31, 1995 are as follows: 1996, $605,000; 1997, $244,000; 1998, $160,000; 1999,
$129,000; 2000, $102,000 and thereafter, $136,000. Lease expense totaled
$1,076,000, $942,000 and $739,000 for each of the three years ended March 31,
1995, 1994 and 1993, respectively.
 
 Royalties
 
  The Company has purchased product rights, assembly blueprints and related
documentation for certain products under arrangements calling for licensing
royalties over periods up to 12 years. Royalty fees generally range from 4% to
10% of specified product sales. Total royalty payments made under these
arrangements approximated $144,000, $185,000 and $228,000 in 1995, 1994 and
1993, respectively.
 
 Product Liability
 
  The Company is a party to various claims and legal actions arising during the
ordinary course of business. With respect to product liability claims, the
Company's costs and any potential judgments resulting from such claims would be
covered by the Company's product liability insurance, except for deductible
limits and self-insured retentions. The Company intends to defend such claims
in cooperation with its insurers. It is management's opinion that any eventual
outcome will not have a material adverse effect on the Company's financial
position or results of operations.
 
(11) COMMON STOCK PURCHASE RIGHTS
 
  The Company has a common stock purchase rights plan under which it has issued
one common stock purchase right (Right) for each outstanding share of common
stock. Each Right entitles the holder to purchase one-fourth share of common
stock at a price of $8, subject to adjustment.
 
  The Rights become exercisable ten days after any public announcement that a
person or group has acquired beneficial ownership of 20% or more of the
Company's common stock, or announces a tender offer or exchange offer for 20%
of the stock, without the prior approval of the Board of Directors.
 
  If a person or group acquires beneficial ownership of 20% or more of the
Company, then each holder of a Right, other than the acquiring person or group,
may thereafter receive upon exercise of four times the exercise price, that
number of shares of the Company's common stock or equivalents having a market
value of eight times the exercise price.
 
  Subsequent to such stock acquisition, if the Company is acquired in a merger
or other business combination, or 50% of the Company's assets or earning power
is sold or transferred, each holder of a Right, other than the acquiring person
or group, may thereafter receive, upon the exercise and payment of four times
the exercise price, that number of shares of common stock of the acquiring
company having a market value of eight times the exercise price at the time of
such transaction.

                            MARCH 31, 1995 AND 1994
 
  With certain restrictions, the Board of Directors may redeem the Rights or
exchange them for shares of common stock. The Rights will expire on February
27, 2000, unless extended or unless earlier redeemed or exchanged by the
Company. At March 31, 1995, the Company has 1,692,358 shares of common stock
reserved for the Rights.
 
(12) STOCK OPTIONS
 
  The Company has a stock option plan which provides for the granting to
directors and employees of the Company options to purchase up to 1,200,000
shares of the Company's common stock. The options may be granted for terms up
to ten years, and the exercise price must be at least equal to the fair market
value of the common stock on the date of grant. Options are exercisable one
year after the date of grant. If an option is granted to any person owning more
than 10% of the voting power of all classes of the Company's capital stock, the
exercise price of the option must be at least 110% of the fair market value of
the common stock on the date of grant. At March 31, 1995, options for 724,766
shares were outstanding, of which 584,766 shares were exercisable. At that
date, 221,770 shares remained available for future grant under the plan. The
aggregate option price for outstanding options at March 31, 1995, 1994 and 1993
was $4,268,000, $4,882,000 and $4,609,000, respectively.
 
  Transactions and other information relating to stock options for each of the
three years ended March 31, 1995 are summarized as follows:

  The "other" component of income tax expense represents the tax effect of
deferred tax charges (principally reserves not yet deductible for Federal and
state income tax purposes), stock option benefits and purchase accounting
liability payments.
 
  As discussed in note 1, the Company adopted Statement 109 in its fiscal year
ended March 31, 1994, and as allowed in Statement 109, elected to apply the
provisions of Statement 109 retroactively to April 1, 1988. The cumulative
effect of the change in the method of accounting for income taxes as of April
1, 1988 was a charge to retained earnings and stockholders' equity of
approximately $3.1 million. This cumulative effect adjustment principally
reflects financial statement and tax basis differences in the value of
inventory and buildings resulting from the Castle Company acquisition as
reported in the fiscal year ended March 31, 1988. In addition to the cumulative
effect adjustment, a separate adjustment was required under Statement 109 to
restate any assets or liabilities previously recorded net-of-tax under Opinion
11 to their pretax (gross) amounts. The pretax (gross) amount is the

amount of asset or liability which would have been recorded if net-of-tax
accounting had not been used in the acquisition. The effect of this adjustment
on the Company was to eliminate the remaining balance in the deferred tax asset
account relating to the previously recorded net-of-tax adjustments and to
increase the building asset account by approximately $2.1 million. For all
periods ending subsequent to April 1, 1988, and throughout the life of the
building, the annual financial statement impact (i.e., depreciation expense
less deferred tax impact) associated with this step-up in the building asset
will be a reduction of net income of $51,000. The financial statements for the
years ending subsequent to April 1, 1988 have been restated to comply with the
provisions of Statement 109.
 
  The tax effects of temporary differences that give rise to significant
portions of deferred tax assets and liabilities at March 31, 1995 and 1994 are

 Retirement Plan
 
  The Company provides a defined contribution retirement plan covering certain
employees of the Company with at least one year of service. The plan provides
for contributions of 3% of salaries and wages, exclusive of bonuses, plus 3% of
each participant's compensation in excess of the Social Security earnings base.
Amounts allocated to a participant's account are subject to a vesting schedule
under which a participant would be 20% vested after one year of service and 20%
vested for each year of service thereafter. Contributions to the plan totaled
$1,049,000, $1,069,000 and $954,000 for the years ended March 31, 1995, 1994
and 1993, respectively.
 
 Savings and Thrift Plans
 
  The Company provides savings and thrift plans in which all employees are
eligible to participate. Participants may contribute up to 6% of their
compensation while receiving up to 50% matching contributions from the Company.
The Company's contributions become vested at a rate of 20% after the first year
of service and 20% for each year of service thereafter. The Company's
contributions under the plan totaled $708,000, $704,000 and $605,000 for the
years ended March 31, 1995, 1994 and 1993, respectively.
 
 Supplemental Executive Retirement Plan
 
  The Company has a Supplemental Executive Retirement Plan (SERP) for officers
of the Company and its subsidiaries. The SERP supplements retirement benefits
payable to officers under the Retirement Plan and the Savings and Thrift Plan.
Contributions to the SERP began in 1992 and were $106,000, $87,000 and $76,000
for 1995, 1994 and 1993, respectively. The contributions are actuarially
determined based on age, service time and salary levels of participants.
 
 Postretirement Medical Benefits
 
  The Company sponsors a defined medical benefit plan for retired employees.
Under the plan, benefits are payable to three separate employee groups. The
Company is committed to pay a fixed dollar contribution towards retiree medical
benefits for two of the component groups. The third group, consisting of
employees who retire between the ages of 62 and 65 (with a service requirement
of 25 years), is covered for medical benefits under the same plan as active
employees, with such benefits being discontinued when the participant turns 65.
The Company does not fund benefits in advance of payment thereof.
 
  The following table sets forth the plan's funded status reconciled with the
amount shown in the Company's consolidated balance sheets at March 31, 1995 and
1994:

  For measurement purposes, a 10.0% annual rate of increase in the per capita
cost of covered health care benefits (nonfixed portion) was assumed for 1995;
the rate was assumed to decrease gradually to 5.0% for 2005 and remain at that
level thereafter. The health care cost trend rate assumption only affects
retirees ages 62-65, as all other contributions are fixed. The effect of a 1.0%
increase in the assumed health care cost trend to each year would increase the
accumulated postretirement benefit obligation as of March 31, 1995 by $32,000
and the aggregate net periodic postretirement benefit cost for the year ended
March 31, 1995 would remain approximately equal. The weighted average discount
rate used in determining the accumulated postretirement benefit obligation was
8.5%, 8.0% and 8.0% in 1995, 1994 and 1993, respectively.

The Board of Directors and Stockholders
MDT Corporation:
 
  Under date of May 16, 1995, except as to Note 17 which is as of June 4, 1995,
we reported on the consolidated balance sheets of MDT Corporation and
subsidiaries as of March 31, 1995 and 1994, and the related consolidated
statements of income, retained earnings, and cash flows for each of the years
in the three-year period ended March 31, 1995, as contained in the 1995 annual
report to Stockholders. These consolidated financial statements and our report
thereon are incorporated by reference in the annual report on Form 10-K for the
year 1995. Our report refers to a change in the method of accounting for
inventories. In connection with our audits of the aforementioned consolidated
financial statements, we have also audited the related financial statement
schedule VIII included herein. This financial statement schedule is the
responsibility of the Company's management. Our responsibility is to express an
opinion on this financial statement schedule based on our audits.
 
  In our opinion, such financial statement schedule, when considered in
relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.

          A.   The Parties agree that the Seller shall through August 31, 1995
(or such other date as may be determined under the Transition Services
Agreement, such date, in either case, being referred to as the "Inventory
Delivery Date") maintain in its possession (and in a commercially reasonable
manner) the Equipment and the Inventory, exclusive of Inventory delivered from
time to time to the Buyer or at the direction of the Buyer pursuant to the
Transition Services Agreement and Inventory consigned to third parties or other
sales representatives by the Seller (the "Consignment Inventory").  The Seller
and Buyer shall jointly perform a physical inventory (the "Delivery Date
Inventory") of the Equipment and Inventory (collectively "Inventory Assets") on
hand as of the Inventory Delivery Date (including any Additional Consignment
Inventory, as defined in paragraph 2.06.E, below) in accordance with the
provisions of this Section, and such Inventory Assets shall then immediately be
delivered into the possession of the Buyer at Seller's facility in Charleston,
South Carolina.  Buyer shall have reasonable access to the facilities of Seller
and the Equipment and Inventory, and the use of Employees and computer records
to such extent as Buyer may reasonably request for the purpose of conducting the
Delivery Date Inventory.  In addition, Buyer and Seller shall commence such
Delivery Date Inventory on or about five business days before the Inventory
Delivery Date, for the purpose of enabling Seller to prepare and deliver  the
Preliminary Valuation (as defined below) on the Inventory Delivery Date.

          B.   The Delivery Date Inventory shall be used by the Seller to
produce a schedule of all Inventory Assets (including the Additional Consignment
Inventory) as of the Inventory Delivery Date (the "Schedule of Equipment and
Inventory"), including a preliminary good faith determination of the value of
the Inventory included in the Inventory Assets (the "Preliminary Valuation")
determined in accordance with the provisions of this Section and as specified on
                                                                                
Schedule 2.06.  The assets set forth in the Schedule of Equipment and
- -------------                                                        
Inventory(collectively "Tangible Assets") shall be acquired and paid for by the
Buyer pursuant to the provisions of Section 2.08 and Section 2.09.  The Tangible
Assets shall be valued as follows: (i) Inventory (including Additional
Consignment Inventory) shall be valued in accordance with Schedule 2.06 attached
                                                          -------------         
hereto, and (ii) the Equipment shall be valued at One Hundred Fifty Thousand
Dollars ($150,000).  The aggregate value of all of the Equipment and Inventory,
including the value of the Additional Consignment Inventory, as determined from
the Schedule

                                       7
<PAGE>
 
of Equipment and Inventory, is herein referred to as the "Tangible Asset Value".

          C.   The determination of the Tangible Asset Value shall become final
upon mutual agreement of the Parties or upon final determination of the
Independent Firm, as set forth below.  Buyer or Buyer's accountants shall review
the Schedule of Equipment and Inventory (including any corresponding work papers
of the Seller's auditors) and report to Seller and the Seller's auditors of any
discrepancy in writing within thirty (30) days of receipt thereof (the "Dispute
Period").  Buyer's failure to deliver a dispute notice pursuant to this Section
prior to termination of the Dispute Period shall be deemed for purposes of this
Section to be acceptance by Buyer of the valuation set forth in the Schedule of
Equipment and Inventory.  Any dispute notice delivered by Buyer shall set forth
in reasonable detail the elements of the Schedule of Equipment and Inventory
with which Buyer disagrees.  Seller and Buyer will have 15 days from the date of
delivery of Buyer's dispute notice to resolve the subject dispute and agree in
writing upon the Tangible Asset Value.  If Buyer and Seller do not reach a
resolution within such time period, the items remaining in dispute, at the
election of either Party, shall be submitted for resolution to the Atlanta,
Georgia office of KPMG Peat Marwick or such other "big six" accounting firm as
Buyer and Seller shall mutually agree upon (the "Independent Firm").  The
Independent Firm shall be instructed that its determination shall be based on
(i) the provisions of this Agreement, including Schedule 2.06, and (ii)
                                                -------------          
Generally Accepted Accounting Principles, consistently applied ("GAAP");
                                                                        
provided, however, that to the extent the provisions of Schedule 2.06 conflict
- --------  -------                                                             
with GAAP, Schedule 2.06 shall control.  The Independent Firm shall, within
thirty days after such submission, determine and report upon all such disputed
items, and its report shall be final, conclusive and binding on Buyer and Seller
for purposes of this Section.  The fees and disbursements of the Independent
Firm shall be shared equally by Buyer and Seller.

          D.   Notwithstanding anything herein to the contrary, the Tangible
Asset Value will be reduced by the value of any Equipment set forth on Schedule
                                                                       --------
2.01(c) that is not included on the Schedule of Equipment and Inventory (other
- -------                                                                       
than due to customary supply shrinkage), or is not in reasonably good condition
and repair (ordinary wear and tear accepted) on the Inventory Delivery Date,
unless the Seller or MDT replaces (with Equipment of the same or equivalent
make, model and year) or repairs such Equipment prior to the release of any
Escrowed Funds to the Seller.  For purposes of this paragraph, items of
Equipment that are not included on the Schedule of Equipment and Inventory, or
are not in the required operating condition on the Inventory Delivery Date, will
be deemed to have such value as agreed to by the Parties or as determined by the
Independent Firm.  Irrespective of the foregoing, Seller shall have an absolute
obligation to promptly repair or replace (in accordance with this paragraph) all
Equipment not delivered at the Inventory Delivery Date.

                                       8

          E.  On or prior to June 30, 1995, Seller and Buyer shall jointly
perform a physical inventory of all Consignment Inventory which as of such date
(i) has been returned to Seller's facilities in Charleston, South Carolina or
has otherwise been verified to Seller's and Buyer's reasonable satisfaction as
being consigned to and in the possession of third parties, and (ii) is
determined by both Seller and Buyer to be in reasonably good operating and
salable condition, ordinary wear and tear excepted (such items of Consignment
Inventory being collectively referred to as the "Initial Consignment
Inventory").  Such Initial Consignment Inventory shall be valued as of such date
in accordance with the provisions of Schedule 2.06 attached hereto (the
"Consignment Inventory Value").  For purposes of this Agreement, all items of
Consignment Inventory meeting the criteria set forth in clauses (i) and (ii)
above and appearing on the Schedule of Equipment and Inventory as of the
Inventory Delivery Date but which were not included in the Initial Consignment
Inventory shall constitute "Additional Consignment Inventory."

          2.07 ESCROW.  At the Closing, Buyer shall deliver the amount of
$1,600,000 (the "Escrowed Funds") to Fidelity National Title Insurance Company,
Irvine, California (the "Escrow Agent") which shall be deposited into a money
market interest bearing account in accordance with the terms of a certain Escrow
Agreement to be entered into by and between Buyer, Seller and Escrow Agent in a
form reasonably acceptable to Seller and Buyer and consistent with the terms of
this Agreement.  All fees with respect to establishment and normal maintenance
or administration of the Escrow Agreement shall be borne equally by  Buyer and
Seller. The Escrowed Funds shall be held in escrow by the Escrow Agent until
disbursed in accordance with the terms of Section 2.08 of this Agreement and the
Escrow Agreement.  Upon termination of the escrow, the Escrow Agent shall
deliver to Buyer any cash (plus allocable interest accumulated thereon) to which
Buyer may be entitled under Section 2.08 hereunder, with any balance of the
Escrowed Funds, plus allocable interest, if any, to be delivered to Seller.  If
a Net Asset Value Shortfall (as defined in Section 2.08) does not occur, then
all of the Escrowed Funds, together with allocable interest, shall be delivered
to the Seller.

          2.08 DISBURSEMENT OF ESCROWED FUNDS.

          A.   Buyer and Seller shall cause the Escrow Agent to disburse to
Seller on July 1, 1995 from the Escrowed Funds an amount equal to the

together with allocable interest accumulated on such amount from the Closing
Date.

          B.   Buyer and Seller shall cause the Escrow Agent to disburse to
Seller on the Inventory Delivery Date from the Escrowed Funds an amount equal to
the sum of the following (together with allocable interest on such amount from
the Closing Date):

<PAGE>
 
               1. Eighty percent (80%) of the amount of Seller's Preliminary
     Valuation:

               2.  $150,000 (as the pre-established value of the Equipment): and

               3.  The full amount of any outstanding and unpaid invoices issued
     by Seller to Buyer for Previously Delivered Inventory shipped by Seller
     prior to the Inventory Delivery Date in accordance with the terms of the
     Transition Services Agreement (the "Unpaid Invoice Amount").

          C.   On the first business day following the delivery by Buyer of any
dispute notice pursuant to Section 2.06.C hereof, Buyer and Seller shall cause
the Escrow Agent to disburse to Buyer or Seller, as the case may be, from any
Escrowed Funds remaining after the disbursements provided in paragraphs A and B
above, an amount equal to the undisputed amount, as determined on the basis of
Buyer's and Seller's dispute notices for the purposes of determining the
Tangible Asset Value (together with allocable interest on such amount from the
Closing Date).

          D.   On the first business day following the final determination of
the Tangible Asset Value in accordance with Section 2.06.C, Buyer and Seller
shall cause the Escrow Agent to make disbursements from any Escrowed Funds
remaining after the disbursements provided in paragraphs A, B and C above as
follows:

               1.  If the sum of (a) the Tangible Asset Value, (b) the Consigned
     Inventory Value, and (c) the Unpaid Invoice Amount is less than One Million
     and Six Hundred Sixty-Five Thousand Dollars ($1,665,000) (the "Minimum
     Value"), then such occurrence shall constitute a "Net Asset Value
     Shortfall."  Buyer and Seller shall cause the Escrow Agent to disburse to
     Buyer from the remaining Escrowed Funds an amount equal to the amount of
     any Net Asset Value Shortfall less the principal amount (if any) previously
                                   ----                                         
     distributed to Buyer pursuant to paragraph C above (together with allocable
     interest on such amount from the Closing Date).

               2.  Buyer and Seller shall cause the Escrow Agent to disburse to
     Seller any and all Escrowed Funds (and allocable interest) remaining after
     making any disbursements required under paragraphs A, B and C and
     subparagraph D.1 above.

          2.09 ADDITIONAL PAYMENT FROM SELLER.  To the extent that the sum of
(a) the Tangible Asset Value, (b) the Consigned Inventory Value, and (c) the
Unpaid Invoice Amount exceeds the Minimum Value, the Buyer shall pay such excess
to the Seller in cash within ten business days after the final determination of
the Tangible Asset Value pursuant to Section 2.06.C.

to own its properties and to carry on its business as now owned and operated by
it, and is qualified to do business in any every state where the nature of the
Seller's business is such that it is required to qualify to do business in such
state and the failure to so qualify is likely to have a material adverse affect
on Seller, the Assets or the Business.

          3.02 TITLE TO ASSETS.  The Seller has good and marketable title to all
Assets, as described on the Schedules hereto, free and clear of restrictions on
transfer or assignment, or mortgages, liens, pledges, charges, encumbrances,
equities or claims.  None of the Assets are leased by Seller from third parties.
All Equipment is in reasonably good operating condition and repair, ordinary
wear and tear excepted.

          3.03 TAX RETURNS.  Within the times and in the manner prescribed by
law, the Seller has filed all federal, state and local tax returns required by
law in respect of the Assets and the Business and has paid (or is contesting in
good faith) all taxes, assessments and penalties due and payable thereon.

          3.04 CONTRACTS.  Schedule 3.04 and Schedule 2.01(g) list all the
                           -------------     ----------------             
contracts (the "Material Contracts") to which the Seller is a party and which
relate in any material respect to the Business, exclusive of any such contracts
relating to MDT, Seller and their Affiliates generally or to all of Seller's
existing businesses generally.  Each of the Material Contracts is valid and in
full force and effect, and there has not been any default by the Seller or, to
Seller's knowledge, any of the third parties that are a party to any of said
Material Contracts.  The Seller has not received notice that any party to any of
the Material Contracts intends to cancel or terminate any of the Material

infringe on or otherwise violate any rights of others.  At the Closing, the
Seller shall have executed and delivered to Buyer assignments of all the
Licenses that are assignable.  With respect to any License in which the consent
of a governmental authority or third party is required, Seller shall cooperate

     respect of any liability or obligation of the Business or relating to the

<PAGE>
 
     exist if the Damages arise as a result of Buyer's breach of this Agreement
     or Buyer has agreed herein to be responsible for such Damages.

execution and delivery hereof and the Closing hereunder and shall expire when

therefor has expired and cannot thereafter be asserted.  No claim shall be made
for the breach of any representation or warranty contained in or made pursuant
to this Agreement or any of the Related Agreements after the date on which such
representation or warranty terminates as set forth in this Section; provided,
however, that in the event that it is asserted that any Party has violated any
of the representations and warranties made by it and a claim for indemnification
is made thereon, such representation or warranty shall survive until the final
adjudication of the issue in the form of a final, non-appealable judgment by a
court of law having or arbitrator jurisdiction of the matter or until the issue
is otherwise settled by the Buyer and Seller and MDT.

          9.03 INDEMNIFICATION.

          (A) BY THE SELLER OR MDT.  The Seller and MDT shall jointly and
     severally indemnify, save, defend and hold harmless Buyer and Buyer's
     directors, officers, agents, employees and Affiliates (collectively, the
     "Buyer Indemnified Parties'") from and against any and all costs, lawsuits,
     losses, liabilities, deficiencies, claims and expenses, including interest,
     penalties, attorneys' fees and all amounts paid in investigation, defense
     or settlement of any of the foregoing (collectively referred to herein as
     "Damages"), incurred in connection with or arising out of or resulting from
     or incident to any breach of any covenant or warranty, or

                                       27
<PAGE>
 
     the inaccuracy of any representation, made by Seller in or pursuant to this
     Agreement or any other agreement contemplated hereby or in any schedule,
     certificate, exhibit, or other instrument furnished or to be furnished by
     the Seller under this Agreement.

          (B) BY BUYER.  Buyer shall indemnify, save, defend and hold harmless
     the Seller, MDT and the Seller' directors, officers, agents, employees and
     Affiliates (collectively, the "the Seller' Indemnified Parties'") from and
     against any and all Damages incurred in connection with or arising out of
     or resulting from or incident to any breach of any covenant or warranty, or
     the inaccuracy of any representation, made by Buyer in or pursuant to this
     Agreement or any other agreement contemplated hereby or in any schedule,
     certificate, exhibit, or other instrument furnished or to be furnished by
     Buyer under this Agreement.

          (C) DEFENSE OF CLAIMS.  If any lawsuit or enforcement action is filed
     against any Party entitled to the benefit of indemnity hereunder, written
     notice thereof describing such lawsuit or enforcement action in reasonable
     detail and indicating the amount (estimated, if necessary) or good faith
     estimate of the reasonably foreseeable estimated amount of Damages (which
     estimate shall in no way limit the amount of indemnification the
     indemnified Party is entitled to receive hereunder), shall be given to the
     indemnifying Party as promptly as practicable (and in any event within
     twenty (20) days, after the service of the citation or summons); provided
     that the failure of any indemnified Party to give timely notice shall not
     affect its rights to indemnification hereunder to the extent that the
     indemnified Party demonstrates that the actual damages to the indemnifying
     Party caused by such failure to so notify within twenty (20) days are less
     than the amount the indemnified Party is entitled to recover.  After such
     notice, if the indemnifying Party elects to compromise or defend any such
     asserted liability and to assume all obligations contained in this Section
     9.03 to indemnify the indemnified Party, then the indemnifying Party shall
     be entitled, if it so elects, to take control of the defense and
     investigation of such lawsuit or action and to employ and engage attorneys
     of its own choice to handle and defend the same, at the indemnifying
     Party's cost, risk and expense, and such indemnified Party shall cooperate
     in all reasonable respects, at the indemnifying Party's cost, risk and
     expense, with the indemnifying Party and such attorneys in the
     investigation, trial, and defense of such lawsuit or action and any appeal
     arising therefrom; provided, however, that the indemnified Party

                                       28
<PAGE>
 
     may, at its own cost, risk and expense, participate in such investigation,
     trial and defense of such lawsuit or action and any appeal arising
     therefrom.  If the indemnifying Party promptly notifies the indemnified
     Party that it intends to defend the claim and to assume all obligations
     contained in this Section 9.03 to indemnify the indemnified Party, the
     indemnified Party shall not pay, settle or compromise such claim without
     the indemnifying Party's consent, which consent shall not be unreasonably
     withheld.  If the indemnifying Party elects not to defend the claim or the
     indemnified Party, the indemnified Party may, but shall not be obligated to
     defend, or the indemnified Party may compromise or settle (exercising
     reasonable business judgment) the claim or other matter on behalf, for the
     account, and at the risk, of the indemnifying Party.

          (D) THIRD PARTY CLAIMS.  The provisions of this Section 9.03 are not
     limited to matters asserted by the Parties', but cover costs, losses,
     liabilities, damages, lawsuits, claims and expenses incurred in connection
     with third party claims.

          9.04 LIMITATIONS ON INDEMNIFICATION.  (a) Notwithstanding any other
provision contained in this Agreement:

          (i) Seller shall not be obligated to indemnify Buyer or any Buyer
     Indemnified Parties under this Article IX unless the amount for which
     indemnity would be due for the specific claim exceed $2,500 and the
     aggregate of all amounts exceeding such $2,500 for which claims for
     indemnity would otherwise be payable by Seller exceeds $37,500, and, in
     such event, Seller shall be responsible only for the amount in excess of
     such $37,500; and

          (ii) The aggregate indemnity obligation of Seller pursuant to this
     Article IX shall not exceed the Purchase Price received by Seller pursuant
     to this Agreement, provided that, such limitation shall not apply with
     respect to products liability claims with respect to Products shipped by
     Seller prior to the Closing Date.
 
          (b) Any indemnifiable claim with respect to any breach or
nonperformance by either Party of a representation, warranty, covenant or
agreement shall be limited to the amount of actual damages sustained by the
indemnified Party by reason of such breach or nonperformance.  Notwithstanding
anything to the contrary elsewhere in this Agreement, no Party or its Affiliates

     damages in excess of compensatory damages and agrees not to seek punitive
     damages relating to any matter under, arising out of, in connection with or
     relating to this Agreement or any of the Related Agreement in any forum.

Taxes and before reorganization costs.

VIII. Planned Income Before Taxes results shall be realized after the inclusion
of Plan payouts are incorporated into the Income Statement for Plan payouts to
be realized by participants in the Plan.

                              EMPLOYMENT AGREEMENT


          THIS EMPLOYMENT AGREEMENT (this "Agreement") dated as of APRIL 1,
1995, is between MDT CORPORATION, a Delaware corporation ("Employer"), and J.
MILES BRANAGAN ("Employee").

          WHEREAS Employer and Employee desire to enter into an agreement
setting forth the terms and conditions upon which Employee shall be employed by
Employer;


                                  WITNESSETH:

          That in consideration of the mutual covenants and obligations
hereinafter set forth, the parties hereto agree as follows:

          1.  Employment and Term.

               (a) Employer hereby employs Employee and Employee hereby accepts

          (b)  Employee agrees that so long as this Agreement continues in

     described herein and such other executive duties as the Employer's Board Of
     Directors shall assign to him from time to time.

          3.  Covenant.  Employee covenants and agrees that during the term of

however,
<PAGE>
 
that this paragraph shall not limit or restrict Employee's rights to serve on
the boards of directors of noncompeting companies or to make and have personal
investments in such form or manner as will not require his active services in
the daily operations of the businesses in which such investments are made.

          4.  Compensation.

               (a)  Employer shall pay Employee, and Employee hereby agrees to
     accept, as partial compensation for all services rendered hereunder, an
     annual salary of not less than $270,599, payable in semi-monthly
     installments and subject to such deductions and withholdings as are
     required to be made pursuant to applicable governmental laws, rules and
     regulations.

               (b)  Employee shall be entitled to management incentive
     compensation in an amount equivalent to FORTY-FIVE PERCENT (45%) of his
     annual salary, subject to the criteria detailed in the provisions of
     Employer's Management Incentive Compensation Plan.

               (c)  Employer shall also provide Employee with such health care
     benefits, disability insurance and term life insurance as Employer provides
     for its executive employees generally in amounts determined by and
     appropriately adjusted for his compensation, length of service and other
     such relevant criteria, subject to Employee's satisfaction of any
     eligibility criteria for such insurance.

               (d)  Employee shall be entitled to annual vacation time of six
     (6) weeks duration, during which time his compensation shall be paid in

     relocation to California or to any other location within the continental
     limits of the United States in accordance with the terms of the Company's
     relocation policy in effect at that time, provided that the relocation is
     completed within two (2) years from the expiration of this Agreement.

          5.   Expenses.   Employer agrees to pay or reimburse Employee for all
reasonable travel and other expenses incurred by

                                       2
<PAGE>
 
Employee in connection with the performance of his services under this
Agreement, upon presentation of such reasonably detailed expense statements,
vouchers or other supporting information as Employer may from time to time
request.

          6.   Confidentiality.  Employee recognizes and acknowledges that
during his employment by Employer pursuant to this Agreement he may have access
to or may obtain information of a secret, special and unique value to Employer
concerning customers, customer lists, processes, technologies, products,
formulas, devices, designs, inventions, discoveries, plans, strategies and
methods of operation (collectively and individually "Confidential Information").
Employee further recognizes and acknowledges that all Confidential Information
which is now or may hereafter be in his possession is the property of Employer
and that protection of this Confidential Information against unauthorized
disclosure or use is of critical importance to Employer in order to protect
Employer from unfair competition.  Employee therefore agrees that he will not at
any time, either while employed by Employer or afterwards, without the prior
written consent of the Board of Directors of Employer, make any independent use
of such Confidential Information, or knowingly disclose the same, directly or
indirectly, to any other person, firm, corporation or other entity, for any
reason or purpose whatsoever, except to professional advisors of Employer or
others who have a business relationship with Employer and who, in Employee's
judgement, have a business need to know (e.g. advisory board members), and
except on advice of counsel during testimony under subpoena in any court or
before any administrative agency having jurisdiction or during any authorized
governmental inquiry or investigation, provided that Employee shall cooperate
with Employer in taking all reasonable and appropriate steps to assure the
protection of such Confidential Information from unauthorized use or disclosure
outside of such action, proceeding, inquiry or investigation, or except to the
extent that any such Confidential Information shall be in the public domain
other than by reason of Employee's breach of this Paragraph 6.

          7.   Ideas and Inventions.   Employee shall disclose promptly and
thereafter turn over to Employer any and all concepts and ideas for inventions,
improvements, programs, systems, novel techniques, copyrightable materials and
other valuable discoveries, whether patentable or not, which are conceived or
made by Employee solely or jointly with another during the period of employment,
on the time or property of Employer or otherwise, and which are related to the
business or activities of Employer or which Employee conceives as a result of
his employment by Employer.  Employee hereby assigns and agrees to assign to
Employer or its nominee all his interests in any of the foregoing.  Whenever
requested to do so by Employer, Employee shall execute any and all patent
applications, assignments or other transfer instruments which Employer shall
deem necessary to apply for and obtain Letters of Patent of the United States or
any foreign country or other

                                       3
<PAGE>
 
applicable trade secret protection or to otherwise confirm and protect
Employer's interest in and ownership of all such inventions, improvements,
programs, systems, novel techniques, copyrightable materials and other
discoveries.

              8.   Restrictive Covenant.   Employee acknowledges that he is a
key executive and that the services to be rendered hereunder are of a critical
nature to the continued success of Employer.  In view of the value to Employer
of the services of Employee for which Employer has contracted hereunder, and in
recognition of Employer's obligations hereunder, Employee covenants and agrees
as follows:

               (a)  During Employee's employment hereunder and for a period of
     two (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, solicit business for any person, firm or entity
     engaged primarily in developing, manufacturing and marketing medical or
     dental sterility assurance systems and examining and operatory equipment,
     or in any other business in which Employer, from time to time, shall be
     engaged in those cities or counties of the United States in which Employer
     shall then be transacting business, from any client, customer or account of
     Employer, or attempt to convert said persons or entities to other methods
     of using the same or similar products or services as provided by Employer.

               (b)  During Employee's employment hereunder and for a period of
     two (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, engage in developing, manufacturing and marketing
     medical or dental sterility assurance systems and examining and operatory
     equipment or in any other business in which Employer, from time to time,
     shall be engaged, in those cities or counties of the United States in which
     Employer shall then be transacting business.

               (c)  During Employee's employment hereunder, and for a period of
     two (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, solicit for employment or employ any employee of
     Employer.

               As used herein, the term transacting business within "those
cities and counties" includes the carrying on of a business which may be located
elsewhere but which involves sales or any activity within the stipulated city or
county. The covenants contained in this paragraph shall be deemed to be a series
of separate covenants, for each city and county of each state where

                                       4
<PAGE>
 
Employer is carrying on such business.  If in any judicial proceeding a court
shall refuse to enforce all of the separate covenants deemed included in such
action, then such unenforceable covenants shall be deemed eliminated from the
provisions hereof for the purposes of such proceedings to the extent necessary
to permit the remaining separate covenants to be enforced in such proceedings.

          9.   Relief.   It is recognized that in the event of Employee's breach
of Paragraphs 6, 7, or 8, the damages resulting from such breach would be
difficult, if not impossible to ascertain, and that Employer would be subject to
irreparable injury therefrom.  It is, therefore, agreed that Employer, in
addition to and without limiting any other remedy or right it may have, shall be
entitled to such equitable and injunctive relief as may be available to restrain
Employee from violation of any of said covenants, such right to injunctive and
equitable relief, however, to be cumulative and in addition to whatever other
remedies Employer may have in the premises, including the recovery of
consequential but not punitive damages from Employee.

          10.  Termination.

               (a)  This Agreement and the employment of Employee hereunder
     shall terminate upon the occurrence of the first to occur of the following
     events or conditions:

                         (i)  the expiration of the term specified in Paragraph
               1 hereof.

                        (ii)  the death of Employee.

                       (iii)  the incapacity of Employee for a period of six
               consecutive months to perform his duties hereunder.

                        (iv)  the election of the Board of Directors of Employer
               to terminate Employee's employment for "cause", which shall mean
               a determination by the Board of Directors of Employer, in the
               exercise of its sole discretion, that there has been fraud,
               misappropriation, embezzlement, gross and continuing inattention
               to duty, or a substantial breach of this Agreement by Employee.

                         (v)  the election of the Board of Directors of Employer
               to terminate Employee's employment upon the entry of any final
               non-appealable order for relief in respect of Employee under any
               bankruptcy, reorganization, arrangement, insolvency, readjustment
               of debt or similar law of any jurisdiction now or hereafter in
               effect if, in

                                       5
<PAGE>
 
               the good faith determination of the Board of Directors, such
               entry of a final, non-appealable order for relief resulted from
               the willful neglect, financial irresponsibility or moral
               turpitude of Employee.

                        (vi)  Employee's conviction of a crime involving moral
               turpitude.

               (b)  Any termination of this Agreement pursuant to clauses (i) or
     (ii) of Subparagraph (a) of this Paragraph 10 shall be effective on the
     expiration date of this Agreement or the date of death, as the case may be.
     Any termination pursuant to clauses (iii), (iv), (v) or (vi) of
     Subparagraph (a) of this Paragraph 10 shall be effective immediately upon
     delivery of notice of termination to Employee.

               (c)  Upon the expiration or earlier termination of this Agreement
     by Employee or by Employer pursuant to Subparagraph (a) of this Paragraph
     10, Employer's sole obligation shall be to pay Employee or his estate any
     compensation remaining unpaid through the effective date of termination.
     In the case of the death of Employee, however, Employer's obligation shall
     be to pay Employee's designated beneficiary or estate the Employee's salary
     in effect at the time of his death, in semi-monthly installments, and to
     provide Employee's designated beneficiary healthcare benefits on the same
     basis as an active employee for 180 days; to pay the management incentive
     compensation to which the Employee would otherwise have been entitled for
     the fiscal year in which death occurs; and to pay to his designated
     beneficiary or estate the life insurance, retirement and supplementary
     retirement benefits to which they are entitled within 180 days.  Upon the
     termination of this Agreement by Employer without cause, and as the sole
     and exclusive remedy against Employer for the exercise of its right under
     this Agreement to terminate this Agreement without cause,  Employer's sole
     obligation shall be to pay Employee the salary in effect at the time of his
     termination, in semi-monthly installments, to continue his participation in
     the Management Incentive Compensation Plan, to provide healthcare and life
     insurance benefits and to continue his participation in the Retirement
     Plan, as amended, and the Supplemental Executive Retirement Plan, as
     amended, on the same basis as an active employee for the remaining term of
     this Agreement, without any further extensions of such term; provided,
     however, that the amount of salary shall be reduced by the salary Employee
     earns from reasonably comparable employment with another employer; and
     provided further that Employer's obligation to continue healthcare and life
     insurance benefits shall end when Employee is covered under reasonably
     comparable benefit plans provided by another employer.   The resignation of
     Employee in response to a demand by Employer for the relocation of Employee
     outside of the United States shall be

                                       6
<PAGE>
 
     deemed a termination by Employer without cause for purposes of this
     Agreement.

               (d)  The respective rights and obligations of Employer and
     Employee pursuant to Paragraphs 6, 7, 8 and 9 hereof, shall survive the
     expiration or earlier termination of this Agreement.

          11.  Bonding.   Employer may apply for and maintain fidelity bonds or
similar insurance with respect to the acts and omissions of Employee.  Employee
agrees to take such steps and perform such acts as shall be necessary to assist
Employer in obtaining or maintaining in effect such bonds or insurance,
including the completion of the required applications and questionnaires, the
furnishing of any required references, and consenting, upon request, to any
required background, financial or other investigations.  Any such required
information will be treated as confidential and will be returned promptly after
the completion of such investigations.

          12.  Persons Bound.  This Agreement shall inure to the benefit of and
be binding upon Employee, his legal representatives and testate or intestate
distributees, and Employer, its successors and assigns.  This Agreement may not
be assigned by Employee.

          13.  Notices.    Any notice or request required or permitted under
this Agreement shall be in writing and given or made by hand delivery or
registered or certified mail, return receipt requested, addressed to Employer or
to Employee at Employer's then principal place of business, with a copy to
Employee at his home address, as set forth on the records of Employer, or to
either party hereto at such other address or addresses as such party may from
time to time specify for the purpose in a notice similarly given to the other
party.

          14.  No Waiver or Modification.  The waiver of the breach of any term
or condition of this Agreement shall not be deemed to constitute the waiver of
any other or subsequent breach of the same of any other term or condition.  No
amendment or modification of this Agreement shall be valid or binding unless
made in writing and signed by the other party against whom such waiver or
modification is to be enforced.

          15.  Governing Law.  This Agreement shall be construed and enforced in
accordance with the laws of the State of Delaware applicable to agreements made
and to be performed in said State.

          16.  Disputes.  In the event that any suit or other proceeding shall
be brought by Employer or Employee in respect of an alleged breach by or default
in the performance of the other party hereto, the successful party in such suit
or proceeding (on the merits or otherwise) shall be entitled to reimbursement of
all reasonable expenses and charges incurred by it or him in connection

                                       7
<PAGE>
 
with the defense or prosecution of such suit or proceeding, including but not
limited to the reasonable fees and expenses of counsel retained by such party.

          17.  Entire Agreement.   This Agreement represents the entire
agreement of the parties hereto with respect to the subject matter hereof, and
supersedes all prior agreements, including, without limitation, the agreement
dated April 1, 1991, between Employer and Employee. No representation,
condition, provision or term related to or connected with this Agreement exists
except as specifically set forth herein.

          18.  Employee's Warranty.    Employee represents and warrants to
Employer that he is not bound by any agreement or subject to any restriction
which would interfere with or prevent his entering into and carrying out this
Agreement.

          19.  Severability.    The invalidity of all or any part of any
paragraph or subparagraph of this Agreement shall not render invalid the
remainder of this Agreement or of any such paragraph or subparagraph.

                             EMPLOYMENT AGREEMENT


     THIS EMPLOYMENT AGREEMENT (this "Agreement") dated as of APRIL 1, 1995, is
between MDT CORPORATION, a Delaware corporation ("Employer") and THOMAS M. HEIN
("Employee").

     WHEREAS, Employer and Employee desire to enter into an agreement setting
forth the terms and conditions upon which Employee shall be employed by
Employer;


                                  WITNESSETH:


     That in consideration of the mutual covenants and obligations hereinafter
set forth, the parties hereto agree as follows:

     1.   Employment and Term.

          (a)  Employer hereby employs Employee and Employee hereby accepts
     employment with and agrees to serve Employer, in the capacities and subject
     to and upon the terms and conditions  hereinafter set forth.

          (b)  The term of Employee's employment hereunder shall be the four-
     year period commencing on APRIL 1, 1995 and ending on MARCH 31, 1999,
     subject to termination as provided in Paragraph 10 hereof. Notwithstanding
     the foregoing, (i) on the second anniversary of this Agreement, the term
     hereof shall automatically be extended for an additional year, and (ii)
     thereafter, when only two years of the term, as extended pursuant to clause
     (i) or (ii) hereof, shall remain, the term hereof shall again be extended
     for an additional year, such extensions continuing from year to year in the
     same manner; provided, however, in each case that the term shall not be
     extended, if prior to the date of such extension, Employer's Board of
     Directors gives notice to Employee or Employee gives notice to Employer's
     Board of Directors that the term shall not be so extended.

          (c)  Upon the occurrence of a change in control, as hereinafter
     defined, notwithstanding the portion of the term hereof otherwise remaining
     outstanding, the term hereof shall automatically be reinstated as a period
     of four years, commencing upon the date of such change in control. A
     "change in control" for purposes of the preceding sentence shall mean (i)
     without prior approval of the Board of Directors of Employer, a single
     entity or group of affiliated entities acquires more than 50% of the voting
     stock of Employer issued and outstanding immediately prior to such
     acquisition; (ii) the Board of Directors of Employer

                                       1
<PAGE>
 
     approves an unsolicited bid by a single entity or group of affiliated
     entities to acquire more than 50% of the voting stock of Employer issued
     and outstanding immediately prior to the approval of such acquisition, and
     such acquisition is consummated; (iii) the stockholders of Employer approve
     the consummation of any merger of Employer or any sale or other disposition
     of all or substantially all of its assets, if the stockholders of Employer
     immediately before such transaction own, immediately after consummation of
     such transaction, equity securities (other than options and other rights to
     acquire equity securities) possessing less than 50% of the voting power of
     the surviving or acquiring corporation; or (iv) a change in the majority of
     the Board of Directors of Employer during any 24-month period without the
     approval of a majority of directors in office at the beginning of such
     period.

     2.   Duties.

          (a)  Employer agrees to employ Employee as VICE PRESIDENT, FINANCE,
     TREASURER, AND ASSISTANT SECRETARY with responsibility for the duties
     normally associated with such executive position, and for such other
     executive duties as the Employer's Board of Directors shall assign to him
     from time to time, subject at all times to the direction of Employer's
     Board of Directors.

          (b)  Employee agrees that so long as this Agreement continues in
     effect, he shall devote his full business time and energies to the business
     and affairs of Employer; use his best efforts, skills and abilities to
     promote the interests of Employer; and faithfully perform the duties
     described herein and such other executive duties as the Employer's Board of
     Directors shall assign to him from time to time.

     3.   Covenant.  Employee covenants and agrees that during the term of this
     Agreement, he will not, directly or indirectly, either as owner, partner,
     stockholder, broker, dealer, agent, employee or otherwise, engage in any
     other business activity for gain or profit or other pecuniary advantage;
     provided, however, that this paragraph shall not limit or restrict
     Employee's rights to serve on the boards of directors of noncompeting
     companies or to make and have personal investments in such form or manner
     as will not require his active services in the daily operations of the
     businesses in which such investments are made.

     4.   Compensation.

          (a)  Employer shall pay Employee, and Employee hereby agrees to
     accept, as partial compensation for all services rendered hereunder, an
     annual salary of not less than

                                       2
<PAGE>
 
     $140,160, payable in semi-monthly installments and subject to such
     deductions and withholdings as are required to be made pursuant to
     applicable governmental laws, rules and regulations.

          (b)  Employee shall be entitled to management incentive compensation
     in an amount equivalent to THIRTY-FIVE PERCENT (35%) of his annual salary,
     subject to the criteria detailed in the provisions of Employer's Management
     Incentive Compensation Plan.

          (c)  Employer shall also provide Employee with such health care
     benefits, disability insurance and term life insurance as Employer provides
     for its executive employees generally in amounts determined by and
     appropriately adjusted for his compensation, length of service and other
     such relevant criteria, subject to Employee's satisfaction of any
     eligibility criteria for such insurance.

          (d)  Employee shall be entitled to annual vacation time of four (4)
     weeks duration (unless under Employer's vacation policy, he is entitled to
     additional vacation time because of his length of service with the
     Company), during which time his compensation shall be paid in full.

          (e)  Employee shall be entitled to benefits under Employer's
     Retirement Plan, as amended, Supplemental Executive Retirement Plan, as
     amended, and the Post-Retirement Medical Insurance Plan in amounts
     determined by and appropriately adjusted for compensation, length of
     service and other such relevant criteria.

     5.   Expenses.  Employer agrees to pay or reimburse Employee for all
     reasonable travel and other expenses incurred by Employee in connection
     with the performance of his services under this Agreement, upon
     presentation of such reasonably detailed expense statements, vouchers or
     other supporting information, as it may from time to time request.

     6.   Confidentiality.  Employee recognizes and acknowledges that during his
     employment by Employer pursuant to this Agreement he may have access to or
     may obtain information of a secret, special and unique value to Employer
     concerning customers, customer lists, processes, technologies, products,
     formulas, devices, designs, inventions, discoveries, plans, strategies and
     methods of operation (collectively and individually "Confidential
     Information").  Employee further recognizes and acknowledges that all
     Confidential Information which is now or may hereafter be in his possession
     is the property of Employer and that protection of this Confidential
     Information against unauthorized disclosure or use is of critical
     importance to Employer in order to protect Employer from unfair

                                       3
<PAGE>
 
     competition.  Employee therefore agrees that he will not at any time,
     either while employed by Employer or afterwards, without the prior written
     consent of the Board of Directors of Employer, make any independent use of
     such Confidential Information, or knowingly disclose the same, directly or
     indirectly, to any other person, firm, corporation or other entity, for any
     reason or purpose whatsoever, except to professional advisors of Employer
     or others who have a business relationship with Employer and who, in
     Employee's judgment, have a business need to know (e.g. advisory board
     members), and except on advice of counsel during testimony under subpoena
     in any court or before any administrative agency having jurisdiction or
     during any authorized governmental inquiry or investigation, provided that
     Employee shall cooperate with Employer in taking all reasonable and
     appropriate steps to assure the protection of such Confidential Information
     from unauthorized use or disclosure outside of such action, proceeding,
     inquiry or investigation, or except to the extent that any such
     Confidential Information shall be in the public domain other than by reason
     of Employee's breach of this Paragraph 6.

     7.  Ideas and Inventions.  Employee shall disclose promptly and thereafter
     turn over to Employer any and all concepts and ideas for inventions,
     improvements, programs, systems, novel techniques, copyrightable materials
     and other valuable discoveries, whether patentable or not, which are
     conceived or made by Employee solely or jointly with another during the
     period of employment, on the time or property of Employer or otherwise, and
     which are related to the business or activities of Employer or which
     Employee conceives as a result of his employment by Employer.  Employee
     hereby assigns and agrees to assign to Employer or its nominee all his
     interests in any of the foregoing.  Whenever requested to do so by
     Employer, Employee shall execute any and all patent applications,
     assignments or other transfer instruments which Employer shall deem
     necessary to apply for and obtain Letters of Patent of the United States or
     any foreign country or other applicable trade secret protection or to
     otherwise confirm and protect Employer's interest in and ownership of all
     such inventions, improvements, programs, systems, novel techniques,
     copyrightable materials and other discoveries.

     8.   Restrictive Covenant.  Employee acknowledges that he is a key
     executive and that the services to be rendered hereunder are of a critical
     nature to the continued success of Employer. In view of the value to
     Employer of the services of Employee for which Employer has contracted
     hereunder, and in recognition of Employer's obligations hereunder, Employee
     covenants and agrees as follows:

                                       4
<PAGE>
 
          (a)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, solicit business for any person, firm or entity
     engaged primarily in developing, manufacturing and marketing medical or
     dental sterility assurance systems and examining and operatory equipment,
     or in any other business in which Employer, from time to time, shall be
     engaged in those cities or counties of the United States in which Employer
     shall then be transacting business, from any client, customer or account of
     Employer, or attempt to convert said persons or entities to other methods
     of using the same or similar products or services as provided by Employer.
     Not-withstanding the foregoing, in the event of a "change in control", as
     defined in Paragraph 1 hereof, the foregoing restriction shall apply only
     with respect to the business in which MDT Corporation is engaged, the
     cities or counties of the United States in which MDT Corporation transacted
     business and the products or services provided by MDT Corporation
     immediately prior to such change in control.

          (b)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, engage in developing, manufacturing and marketing
     medical or dental sterility assurance systems and examining and operatory
     equipment or in any other business in which Employer, from time to time,
     shall be engaged, in those cities or counties of the United States in which
     Employer shall then be transacting business.   Notwithstanding the
     foregoing in the event of a "change in control", as defined in Paragraph 1
     hereof, the foregoing restriction shall apply only with respect to the
     business in which MDT Corporation is engaged and the cities or counties of
     the United States in which MDT Corporation transacted business and the
     products or services provided by MDT Corporation immediately prior to such
     change in control.

          (c)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, solicit for employment or employ any employee of
     Employer.

          (d)  Subparagraphs (a), (b) and (c) shall not apply in the event the
     Employee resigns within one year following a "change in control", as
     defined in Paragraph 1 hereof, that was not previously approved by the
     Board of Directors of Employer.

                                       5
<PAGE>
 
     As used herein, the term transacting business within "those cities and
     counties" includes the carrying on of a business which may be located
     elsewhere but which involves sales or any activity within the stipulated
     city or county.  The covenants contained in this paragraph shall be deemed
     to be a series of separate covenants, for each city and county of each
     state where Employer is carrying on such business.  If in any judicial
     proceeding a court shall refuse to enforce all of the separate covenants
     deemed included in such action, then such unenforceable covenants shall be
     deemed eliminated from the provisions hereof for the purposes of such
     proceedings to the extent necessary to permit the remaining separate
     covenants to be enforced in such proceedings.

     9.   Relief.  It is recognized that in the event of Employee's breach of
     Paragraphs 6, 7, or 8, the damages resulting from such breach would be
     difficult, if not impossible to ascertain, and that Employer would be
     subject to irreparable injury therefrom.  It is, therefore, agreed that
     Employer, in addition to and without limiting any other remedy or right it
     may have, shall be entitled to such equitable and injunctive relief as may
     be available to restrain Employee from violation of any of said covenants,
     such right to injunctive and equitable relief, however, to be cumulative
     and in addition to whatever other remedies Employer may have in the
     premises, including the recovery of consequential but not punitive damages
     from Employee.

     10.  Termination.

          (a)  This Agreement and the employment of Employee hereunder shall
     terminate upon the occurrence of the first to occur of the following events
     or conditions:

               (i)  the expiration of the term specified in Paragraph 1 hereof.

              (ii)  the death of Employee.

             (iii)  the incapacity of Employee for a period of six consecutive
     months to perform his duties hereunder.

              (iv)  the election of the Board of Directors of Employer to
     terminate Employee's employment for "cause", which shall mean a
     determination by the Board of Directors of Employer in the exercise of its
     sole discretion, that there has been fraud, misappropriation, embezzlement,
     gross and continuing inattention to duty, or a substantial breach of this
     Agreement by Employee.

               (v)  the election of the Board of Directors of Employer to
     terminate Employee's employment upon the entry

                                       6
<PAGE>
 
     of any final non appealable order for relief in respect of Employee under
     any bankruptcy, reorganization, arrangement, insolvency, readjustment of
     debt or similar law of any jurisdiction now or hereafter in effect if, in
     the good faith determination of the Board of Directors, such entry of a
     final, non appealable order for relief resulted from the willful neglect,
     financial irresponsibility or moral turpitude of Employee.

              (vi)  Employee's conviction of a crime involving moral turpitude.

          (b)  Any termination of this Agreement pursuant to clauses (i) or (ii)
     of Subparagraph (a) of this Paragraph 10 shall be effective on the
     expiration date of this Agreement or the date of death, as the case may be.
     Any termination pursuant to clauses (iii), (iv), (v) or (vi) of
     Subparagraph (a) of this Paragraph 10 shall be effective immediately upon
     delivery of notice of termination to Employee.

          (c)  Upon the expiration or earlier termination of this Agreement by
     Employee or by Employer pursuant to Subparagraph (a) of this Paragraph 10,
     other than in connection with a "change in control", as such term is
     defined in Paragraph 1 of this Agreement, Employer's sole obligation shall
     be to pay Employee or his estate any compensation remaining unpaid through
     the effective date of termination. In the case of the death of Employee,
     however, Employer's obligation shall be to pay Employee's designated
     beneficiary or estate the Employee's salary in effect at the time of his
     death, in semi-monthly installments, and to provide Employee's designated
     beneficiary healthcare benefits on the same basis as an active employee for
     180 days; to pay the management incentive compensation to which the
     Employee would otherwise have been entitled for the fiscal year in which
     death occurs; and to pay to his designated beneficiary or estate the life
     insurance, retirement and supplementary retirement benefits to which they
     are entitled within 180 days.  Upon the termination of this Agreement by
     Employer without cause, other than in connection with a "change in
     control," as such term is defined in Paragraph 1 of this Agreement, and as
     the sole and exclusive remedy against Employer for the exercise of its
     right under this Agreement to terminate this Agreement without cause,
     Employer's sole obligation shall be to pay Employee the salary in effect at
     the time of his termination, in semi-monthly installments, to continue his
     participation in the Management Incentive Compensation Plan, to provide
     healthcare and life insurance benefits and to continue his participation in
     the Retirement Plan, as amended, and the Supplemental Executive Retirement
     Plan, as amended, on the same basis as an active employee for the remaining
     term of this Agreement, without any further

                                       7
<PAGE>
 
     extensions of such term; provided, however, that the amount of salary shall
     be reduced by the salary Employee earns from reasonably comparable
     employment with another employer; and provided further that Employer's
     obligation to continue healthcare and life insurance benefits shall end
     when Employee is covered under reasonably comparable benefit plans provided
     by another employer. Upon the termination of this Agreement by Employer
     without cause in connection with a "change in control," as such term is
     defined in Paragraph 1 of this Agreement, and as the sole and exclusive
     remedy against Employer for the exercise of its right under this Agreement
     to terminate this Agreement without cause, Employer's sole obligation shall
     be to pay Employee a lump sum, undiscounted cash payment equal to the
     compensation payable through the remaining term of this Agreement, as such
     term was reinstated under Paragraph 1, to continue his participation in the
     Management Incentive Compensation Plan, to provide healthcare and life
     insurance benefits and to continue his participation in the Retirement
     Plan, as amended, and the Supplemental Executive Retirement Plan, as
     amended, on the same basis as an active employee for the remaining term of
     this Agreement, as such term was reinstated under Paragraph 1, without any
     further extensions of such term; provided, however, that Employer's
     obligation to continue healthcare and life insurance benefits shall end
     when Employee is covered under reasonably comparable benefit plans provided
     by another employer. The resignation of Employee in response to a demand by
     Employer for the relocation of Employee outside of the United States shall
     be deemed a termination by Employer without cause for purposes of this
     Agreement.

          (d)  The respective rights and obligations of Employer and Employee
     pursuant to Paragraphs 6, 7, 8 and 9 hereof, shall survive the expiration
     or earlier termination of this Agreement.

     11.  Bonding.  Employer may apply for and maintain fidelity bonds or
     similar insurance with respect to the acts and omissions of Employee.
     Employee agrees to take such steps and perform such acts as shall be
     necessary to assist Employer in obtaining or maintaining in effect such
     bonds or insurance, including the completion of the required applications
     and questionnaires, the furnishing of  any  required references, and
     consenting, upon request, to any required background, financial or other
     investigations.  Any such required information will be treated as
     confidential and will be returned promptly after the completion of such
     investigations.

     12.  Persons Bound.  This Agreement shall inure to the benefit of and be
     binding upon Employee, his legal representatives and testate or intestate
     distributees, and

                                       8
<PAGE>
 
     Employer, its successors and assigns.  This Agreement may not be assigned
     by Employee.

     13.  Notices.  Any notice or request required or permitted under this
     Agreement shall be in writing and given or made by hand delivery or
     registered or certified mail, return receipt requested, addressed to
     Employer or to Employee at Employer's then principal place of business,
     with a copy to Employee at his home address, as set forth on the records of
     Employer, or to either party hereto at such other address or addresses as
     such party may from time to time specify for the purpose in a notice
     similarly given to the other party.

     14.  No Waiver or Modification.  The waiver of the breach of any term or
     condition of this Agreement shall not be deemed to constitute the waiver of
     any other or subsequent breach of the same of any other term or condition.
     No amendment or modification of this Agreement shall be valid or binding
     unless made in writing and signed by the other party against whom such
     waiver or modification is to be enforced.

     15.  Governing Law.  This Agreement shall be construed and enforced in
     accordance with the laws of the State of Delaware applicable to agreements
     made and to be performed in said State.

     16.  Disputes.  In the event that any suit or other proceeding shall be
     brought by Employer or Employee in respect of an alleged breach by or
     default in the performance of the other party hereto, the successful party
     in such suit or proceeding (on the merits or otherwise) shall be entitled
     to reimbursement of all reasonable expenses and charges incurred by it or
     him in connection with the defense or prosecution of such suit or
     proceeding, including but not limited to the reasonable fees and expenses
     of counsel retained by such party.

     17.  Entire Agreement.  This Agreement represents the entire agreement of
     the parties hereto with respect to the subject matter hereof, and
     supersedes all prior agreements between Employer and Employee.  No
     representation, condition, provision or term related to or connected with
     this Agreement exists except as specifically set forth herein.

     18.  Employee's Warranty.  Employee represents and warrants to Employer
     that he is not bound by any agreement or subject to any restriction which
     would interfere with or prevent his entering into and carrying out this
     Agreement.

     19.  Severability.  The invalidity of all or any part of any paragraph or
     subparagraph of this Agreement shall not render invalid the remainder of
     this Agreement or of any such paragraph or subparagraph.

                             EMPLOYMENT AGREEMENT


     THIS EMPLOYMENT AGREEMENT (this "Agreement") dated as of APRIL 1, 1995, is
between MDT CORPORATION, a Delaware corporation ("Employer") and WILLIAM T.
HILVERT ("Employee").

     WHEREAS, Employer and Employee desire to enter into an agreement setting
forth the terms and conditions upon which Employee shall be employed by
Employer;


                                  WITNESSETH:


     That in consideration of the mutual covenants and obligations hereinafter
set forth, the parties hereto agree as follows:

     1.   Employment and Term.

          (a)  Employer hereby employs Employee and Employee hereby accepts
     employment with and agrees to serve Employer, in the capacities and subject
     to and upon the terms and conditions  hereinafter set forth.

          (b)  The term of Employee's employment hereunder shall be the four-
     year period commencing on APRIL 1, 1995 and ending on MARCH 31, 1999,
     subject to termination as provided in Paragraph 10 hereof. Notwithstanding
     the foregoing, (i) on the second anniversary of this Agreement, the term
     hereof shall automatically be extended for an additional year, and (ii)
     thereafter, when only two years of the term, as extended pursuant to clause
     (i) or (ii) hereof, shall remain, the term hereof shall again be extended
     for an additional year, such extensions continuing from year to year in the
     same manner; provided, however, in each case that the term shall not be
     extended, if prior to the date of such extension, Employer's Board of
     Directors gives notice to Employee or Employee gives notice to Employer's
     Board of Directors that the term shall not be so extended.

          (c)  Upon the occurrence of a change in control, as hereinafter
     defined, notwithstanding the portion of the term hereof otherwise remaining
     outstanding, the term hereof shall automatically be reinstated as a period
     of four years, commencing upon the date of such change in control. A
     "change in control" for purposes of the preceding sentence shall mean (i)
     without prior approval of the Board of Directors of Employer, a single
     entity or group of affiliated entities acquires more than 50% of the voting
     stock of Employer issued and outstanding immediately prior to such
     acquisition; (ii) the Board of Directors of Employer

                                       1
<PAGE>
 
     approves an unsolicited bid by a single entity or group of affiliated
     entities to acquire more than 50% of the voting stock of Employer issued
     and outstanding immediately prior to the approval of such acquisition, and
     such acquisition is consummated; (iii) the stockholders of Employer approve
     the consummation of any merger of Employer or any sale or other disposition
     of all or substantially all of its assets, if the stockholders of Employer
     immediately before such transaction own, immediately after consummation of
     such transaction, equity securities (other than options and other rights to
     acquire equity securities) possessing less than 50% of the voting power of
     the surviving or acquiring corporation; or (iv) a change in the majority of
     the Board of Directors of Employer during any 24-month period without the
     approval of a majority of directors in office at the beginning of such
     period.

     2.   Duties.

          (a)  Employer agrees to employ Employee as VICE PRESIDENT, HUMAN
     RESOURCES AND ASSISTANT SECRETARY with responsibility for the duties
     normally associated with such executive position, and for such other
     executive duties as the Employer's Board of Directors shall assign to him
     from time to time, subject at all times to the direction of Employer's
     Board of Directors.

          (b)  Employee agrees that so long as this Agreement continues in
     effect, he shall devote his full business time and energies to the business
     and affairs of Employer; use his best efforts, skills and abilities to
     promote the interests of Employer; and faithfully perform the duties
     described herein and such other executive duties as the Employer's Board of
     Directors shall assign to him from time to time.

     3.   Covenant.  Employee covenants and agrees that during the term of this
     Agreement, he will not, directly or indirectly, either as owner, partner,
     stockholder, broker, dealer, agent, employee or otherwise, engage in any
     other business activity for gain or profit or other pecuniary advantage;
     provided, however, that this paragraph shall not limit or restrict
     Employee's rights to serve on the boards of directors of noncompeting
     companies or to make and have personal investments in such form or manner
     as will not require his active services in the daily operations of the
     businesses in which such investments are made.

     4.   Compensation.

          (a)  Employer shall pay Employee, and Employee hereby agrees to
     accept, as partial compensation for all services rendered hereunder, an
     annual salary of not less than

                                       2
<PAGE>
 
     $124,000, payable in semi-monthly installments and subject to such
     deductions and withholdings as are required to be made pursuant to
     applicable governmental laws, rules and regulations.

          (b)  Employee shall be entitled to management incentive compensation
     in an amount equivalent to THIRTY PERCENT (30%) of his annual salary,
     subject to the criteria detailed in the provisions of Employer's Management
     Incentive Compensation Plan.

          (c)  Employer shall also provide Employee with such health care
     benefits, disability insurance and term life insurance as Employer provides
     for its executive employees generally in amounts determined by and
     appropriately adjusted for his compensation, length of service and other
     such relevant criteria, subject to Employee's satisfaction of any
     eligibility criteria for such insurance.

          (d)  Employee shall be entitled to annual vacation time of four (4)
     weeks duration (unless under Employer's vacation policy, he is entitled to
     additional vacation time because of his length of service with the
     Company), during which time his compensation shall be paid in full.

          (e)  Employee shall be entitled to benefits under Employer's
     Retirement Plan, as amended, Supplemental Executive Retirement Plan, as
     amended, and the Post-Retirement Medical Insurance Plan in amounts
     determined by and appropriately adjusted for compensation, length of
     service and other such relevant criteria.

     5.   Expenses.  Employer agrees to pay or reimburse Employee for all
     reasonable travel and other expenses incurred by Employee in connection
     with the performance of his services under this Agreement, upon
     presentation of such reasonably detailed expense statements, vouchers or
     other supporting information, as it may from time to time request.

     6.   Confidentiality.  Employee recognizes and acknowledges that during his
     employment by Employer pursuant to this Agreement he may have access to or
     may obtain information of a secret, special and unique value to Employer
     concerning customers, customer lists, processes, technologies, products,
     formulas, devices, designs, inventions, discoveries, plans, strategies and
     methods of operation (collectively and individually "Confidential
     Information").  Employee further recognizes and acknowledges that all
     Confidential Information which is now or may hereafter be in his possession
     is the property of Employer and that protection of this Confidential
     Information against unauthorized disclosure or use is of critical
     importance to Employer in order to protect Employer from unfair

                                       3
<PAGE>
 
     competition.  Employee therefore agrees that he will not at any time,
     either while employed by Employer or afterwards, without the prior written
     consent of the Board of Directors of Employer, make any independent use of
     such Confidential Information, or knowingly disclose the same, directly or
     indirectly, to any other person, firm, corporation or other entity, for any
     reason or purpose whatsoever, except to professional advisors of Employer
     or others who have a business relationship with Employer and who, in
     Employee's judgment, have a business need to know (e.g. advisory board
     members), and except on advice of counsel during testimony under subpoena
     in any court or before any administrative agency having jurisdiction or
     during any authorized governmental inquiry or investigation, provided that
     Employee shall cooperate with Employer in taking all reasonable and
     appropriate steps to assure the protection of such Confidential Information
     from unauthorized use or disclosure outside of such action, proceeding,
     inquiry or investigation, or except to the extent that any such
     Confidential Information shall be in the public domain other than by reason
     of Employee's breach of this Paragraph 6.

     7.  Ideas and Inventions.  Employee shall disclose promptly and thereafter
     turn over to Employer any and all concepts and ideas for inventions,
     improvements, programs, systems, novel techniques, copyrightable materials
     and other valuable discoveries, whether patentable or not, which are
     conceived or made by Employee solely or jointly with another during the
     period of employment, on the time or property of Employer or otherwise, and
     which are related to the business or activities of Employer or which
     Employee conceives as a result of his employment by Employer.  Employee
     hereby assigns and agrees to assign to Employer or its nominee all his
     interests in any of the foregoing.  Whenever requested to do so by
     Employer, Employee shall execute any and all patent applications,
     assignments or other transfer instruments which Employer shall deem
     necessary to apply for and obtain Letters of Patent of the United States or
     any foreign country or other applicable trade secret protection or to
     otherwise confirm and protect Employer's interest in and ownership of all
     such inventions, improvements, programs, systems, novel techniques,
     copyrightable materials and other discoveries.

     8.   Restrictive Covenant. Employee acknowledges that he is a key executive
     and that the services to be rendered hereunder are of a critical nature to
     the continued success of Employer. In view of the value to Employer of the
     services of Employee for which Employer has contracted hereunder, and in
     recognition of Employer's obligations hereunder, Employee covenants and
     agrees as follows:

                                       4
<PAGE>
 
          (a)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, solicit business for any person, firm or entity
     engaged primarily in developing, manufacturing and marketing medical or
     dental sterility assurance systems and examining and operatory equipment,
     or in any other business in which Employer, from time to time, shall be
     engaged in those cities or counties of the United States in which Employer
     shall then be transacting business, from any client, customer or account of
     Employer, or attempt to convert said persons or entities to other methods
     of using the same or similar products or services as provided by Employer.
     Not-withstanding the foregoing, in the event of a "change in control", as
     defined in Paragraph 1 hereof, the foregoing restriction shall apply only
     with respect to the business in which MDT Corporation is engaged, the
     cities or counties of the United States in which MDT Corporation transacted
     business and the products or services provided by MDT Corporation
     immediately prior to such change in control.

          (b)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, engage in developing, manufacturing and marketing
     medical or dental sterility assurance systems and examining and operatory
     equipment or in any other business in which Employer, from time to time,
     shall be engaged, in those cities or counties of the United States in which
     Employer shall then be transacting business.   Notwithstanding the
     foregoing in the event of a "change in control", as defined in Paragraph 1
     hereof, the foregoing restriction shall apply only with respect to the
     business in which MDT Corporation is engaged and the cities or counties of
     the United States in which MDT Corporation transacted business and the
     products or services provided by MDT Corporation immediately prior to such
     change in control.

          (c)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, solicit for employment or employ any employee of
     Employer.

          (d)  Subparagraphs (a), (b) and (c) shall not apply in the event the
     Employee resigns within one year following a "change in control", as
     defined in Paragraph 1 hereof, that was not previously approved by the
     Board of Directors of Employer.

                                       5
<PAGE>
 
     As used herein, the term transacting business within "those cities and
     counties" includes the carrying on of a business which may be located
     elsewhere but which involves sales or any activity within the stipulated
     city or county. The covenants contained in this paragraph shall be deemed
     to be a series of separate covenants, for each city and county of each
     state where Employer is carrying on such business. If in any judicial
     proceeding a court shall refuse to enforce all of the separate covenants
     deemed included in such action, then such unenforceable covenants shall be
     deemed eliminated from the provisions hereof for the purposes of such
     proceedings to the extent necessary to permit the remaining separate
     covenants to be enforced in such proceedings.

     9.   Relief.  It is recognized that in the event of Employee's breach of
     Paragraphs 6, 7, or 8, the damages resulting from such breach would be
     difficult, if not impossible to ascertain, and that Employer would be
     subject to irreparable injury therefrom.  It is, therefore, agreed that
     Employer, in addition to and without limiting any other remedy or right it
     may have, shall be entitled to such equitable and injunctive relief as may
     be available to restrain Employee from violation of any of said covenants,
     such right to injunctive and equitable relief, however, to be cumulative
     and in addition to whatever other remedies Employer may have in the
     premises, including the recovery of consequential but not punitive damages
     from Employee.

     10.  Termination.

          (a)  This Agreement and the employment of Employee hereunder shall
     terminate upon the occurrence of the first to occur of the following events
     or conditions:

               (i)  the expiration of the term specified in Paragraph 1 hereof.

              (ii)  the death of Employee.

             (iii)  the incapacity of Employee for a period of six consecutive
     months to perform his duties hereunder.

              (iv)  the election of the Board of Directors of Employer to
     terminate Employee's employment for "cause", which shall mean a
     determination by the Board of Directors of Employer in the exercise of its
     sole discretion, that there has been fraud, misappropriation, embezzlement,
     gross and continuing inattention to duty, or a substantial breach of this
     Agreement by Employee.

               (v)  the election of the Board of Directors of Employer to
     terminate Employee's employment upon the entry

                                       6
<PAGE>
 
     of any final non appealable order for relief in respect of Employee under
     any bankruptcy, reorganization, arrangement, insolvency, readjustment of
     debt or similar law of any jurisdiction now or hereafter in effect if, in
     the good faith determination of the Board of Directors, such entry of a
     final, non appealable order for relief resulted from the willful neglect,
     financial irresponsibility or moral turpitude of Employee.

              (vi)  Employee's conviction of a crime involving moral turpitude.

          (b)  Any termination of this Agreement pursuant to clauses (i) or (ii)
     of Subparagraph (a) of this Paragraph 10 shall be effective on the
     expiration date of this Agreement or the date of death, as the case may be.
     Any termination pursuant to clauses (iii), (iv), (v) or (vi) of
     Subparagraph (a) of this Paragraph 10 shall be effective immediately upon
     delivery of notice of termination to Employee.

          (c)  Upon the expiration or earlier termination of this Agreement by
     Employee or by Employer pursuant to Subparagraph (a) of this Paragraph 10,
     other than in connection with a "change in control", as such term is
     defined in Paragraph 1 of this Agreement, Employer's sole obligation shall
     be to pay Employee or his estate any compensation remaining unpaid through
     the effective date of termination. In the case of the death of Employee,
     however, Employer's obligation shall be to pay Employee's designated
     beneficiary or estate the Employee's salary in effect at the time of his
     death, in semi-monthly installments, and to provide Employee's designated
     beneficiary healthcare benefits on the same basis as an active employee for
     180 days; to pay the management incentive compensation to which the
     Employee would otherwise have been entitled for the fiscal year in which
     death occurs; and to pay to his designated beneficiary or estate the life
     insurance, retirement and supplementary retirement benefits to which they
     are entitled within 180 days.  Upon the termination of this Agreement by
     Employer without cause, other than in connection with a "change in
     control," as such term is defined in Paragraph 1 of this Agreement, and as
     the sole and exclusive remedy against Employer for the exercise of its
     right under this Agreement to terminate this Agreement without cause,
     Employer's sole obligation shall be to pay Employee the salary in effect at
     the time of his termination, in semi-monthly installments, to continue his
     participation in the Management Incentive Compensation Plan, to provide
     healthcare and life insurance benefits and to continue his participation in
     the Retirement Plan, as amended, and the Supplemental Executive Retirement
     Plan, as amended, on the same basis as an active employee for the remaining
     term of this Agreement, without any further

                                       7
<PAGE>
 
     extensions of such term; provided, however, that the amount  of salary
     shall be reduced by the salary Employee earns from reasonably comparable
     employment with another employer; and provided further that Employer's
     obligation to continue healthcare and life insurance benefits shall end
     when Employee is covered under reasonably comparable benefit plans provided
     by another employer.  Upon the termination of this Agreement by Employer
     without cause in connection with a "change in control," as such term is
     defined in Paragraph 1 of this Agreement, and as the sole and exclusive
     remedy against Employer for the exercise of its right under this Agreement
     to terminate this Agreement without cause, Employer's sole obligation shall
     be to pay Employee a lump sum, undiscounted cash payment equal to the
     compensation payable through the remaining term of this Agreement, as such
     term was reinstated under Paragraph 1,  to continue his participation in
     the Management Incentive Compensation Plan, to provide healthcare and life
     insurance benefits and to continue his participation in the Retirement
     Plan, as amended, and the Supplemental Executive Retirement Plan, as
     amended, on the same basis as an active employee for the remaining term of
     this Agreement, as such term was reinstated under Paragraph 1, without any
     further extensions of such term; provided, however, that Employer's
     obligation to continue healthcare and life insurance benefits shall end
     when Employee is covered under reasonably comparable benefit plans provided
     by another employer.  The resignation of Employee in response to a demand
     by Employer for the relocation of Employee outside of the United States
     shall be deemed a termination by Employer without cause for purposes of
     this Agreement.

          (d)  The respective rights and obligations of Employer and Employee
     pursuant to Paragraphs 6, 7, 8 and 9 hereof, shall survive the expiration
     or earlier termination of this Agreement.

     11.  Bonding.  Employer may apply for and maintain fidelity bonds or
     similar insurance with respect to the acts and omissions of Employee.
     Employee agrees to take such steps and perform such acts as shall be
     necessary to assist Employer in obtaining or maintaining in effect such
     bonds or insurance, including the completion of the required applications
     and questionnaires, the furnishing of  any  required references, and
     consenting, upon request, to any required background, financial or other
     investigations.  Any such required information will be treated as
     confidential and will be returned promptly after the completion of such
     investigations.

     12.  Persons Bound.  This Agreement shall inure to the benefit of and be
     binding upon Employee, his legal representatives and testate or intestate
     distributees, and

                                       8
<PAGE>
 
     Employer, its successors and assigns.  This Agreement may not be assigned
     by Employee.

     13.  Notices.  Any notice or request required or permitted under this
     Agreement shall be in writing and given or made by hand delivery or
     registered or certified mail, return receipt requested, addressed to
     Employer or to Employee at Employer's then principal place of business,
     with a copy to Employee at his home address, as set forth on the records of
     Employer, or to either party hereto at such other address or addresses as
     such party may from time to time specify for the purpose in a notice
     similarly given to the other party.

     14.  No Waiver or Modification.  The waiver of the breach of any term or
     condition of this Agreement shall not be deemed to constitute the waiver of
     any other or subsequent breach of the same of any other term or condition.
     No amendment or modification of this Agreement shall be valid or binding
     unless made in writing and signed by the other party against whom such
     waiver or modification is to be enforced.

     15.  Governing Law.  This Agreement shall be construed and enforced in
     accordance with the laws of the State of Delaware applicable to agreements
     made and to be performed in said State.

     16.  Disputes.  In the event that any suit or other proceeding shall be
     brought by Employer or Employee in respect of an alleged breach by or
     default in the performance of the other party hereto, the successful party
     in such suit or proceeding (on the merits or otherwise) shall be entitled
     to reimbursement of all reasonable expenses and charges incurred by it or
     him in connection with the defense or prosecution of such suit or
     proceeding, including but not limited to the reasonable fees and expenses
     of counsel retained by such party.

     17.  Entire Agreement.  This Agreement represents the entire agreement of
     the parties hereto with respect to the subject matter hereof, and
     supersedes all prior agreements between Employer and Employee.  No
     representation, condition, provision or term related to or connected with
     this Agreement exists except as specifically set forth herein.

     18.  Employee's Warranty.  Employee represents and warrants to Employer
     that he is not bound by any agreement or subject to any restriction which
     would interfere with or prevent his entering into and carrying out this
     Agreement.

     19.  Severability.  The invalidity of all or any part of any paragraph or
     subparagraph of this Agreement shall not render invalid the remainder of
     this Agreement or of any such paragraph or subparagraph.

                              EMPLOYMENT AGREEMENT


     THIS EMPLOYMENT AGREEMENT (this "Agreement") dated as of APRIL 1, 1995, is
between MDT BIOLOGIC COMPANY, a Delaware corporation ("Employer") and MELVIN K.
NERBY ("Employee").

     WHEREAS, Employer and Employee desire to enter into an agreement setting
forth the terms and conditions upon which Employee shall be employed by
Employer;


                                  WITNESSETH:


     That in consideration of the mutual covenants and obligations hereinafter
set forth, the parties hereto agree as follows:

     1.   Employment and Term.

          (a)  Employer hereby employs Employee and Employee hereby accepts
     employment with and agrees to serve Employer, in the capacities and subject
     to and upon the terms and conditions  hereinafter set forth.

          (b)  The term of Employee's employment hereunder shall be the four-
     year period commencing on APRIL 1, 1995 and ending on MARCH 31, 1999,
     subject to termination as provided in Paragraph 10 hereof. Notwithstanding
     the foregoing, (i) on the second anniversary of this Agreement, the term
     hereof shall automatically be extended for an additional year, and (ii)
     thereafter, when only two years of the term, as extended pursuant to clause
     (i) or (ii) hereof, shall remain, the term hereof shall again be extended
     for an additional year, such extensions continuing from year to year in the
     same manner; provided, however, in each case that the term shall not be
     extended, if prior to the date of such extension, Employer's Board of
     Directors gives notice to Employee or Employee gives notice to Employer's
     Board of Directors that the term shall not be so extended.

          (c)  Upon the occurrence of a change in control, as hereinafter
     defined, notwithstanding the portion of the term hereof otherwise remaining
     outstanding, the term hereof shall automatically be reinstated as a period
     of four years, commencing upon the date of such change in control. A
     "change in control" for purposes of the preceding sentence shall mean (i)
     without prior approval of the Board of Directors of Employer, a single
     entity or group of affiliated entities acquires more than 50% of the voting
     stock of Employer issued and outstanding immediately prior to such
     acquisition; (ii) the Board of Directors of Employer

                                       

                                       1
<PAGE>
 
     approves an unsolicited bid by a single entity or group of affiliated
     entities to acquire more than 50% of the voting stock of Employer issued
     and outstanding immediately prior to the approval of such acquisition, and
     such acquisition is consummated; (iii) the stockholders of Employer approve
     the consummation of any merger of Employer or any sale or other disposition
     of all or substantially all of its assets, if the stockholders of Employer
     immediately before such transaction own, immediately after consummation of
     such transaction, equity securities (other than options and other rights to
     acquire equity securities) possessing less than 50% of the voting power of
     the surviving or acquiring corporation; or (iv) a change in the majority of
     the Board of Directors of Employer during any 24-month period without the
     approval of a majority of directors in office at the beginning of such
     period.

          (d)  Upon the sale or divestiture of MDT Biologic Company,
     notwithstanding the portion of the term hereof otherwise remaining
     outstanding, the term hereof shall automatically be reinstated as a period
     of four years, commencing upon the date of such sale or divestiture.

     2.   Duties.

          (a)  Employer agrees to employ Employee as PRESIDENT with
     responsibility for the duties normally associated with such executive
     position, and for such other executive duties as the Employer's Board of
     Directors shall assign to him from time to time, subject at all times to
     the direction of Employer's Board of Directors.

          (b)  Employee agrees that so long as this Agreement continues in
     effect, he shall devote his full business time and energies to the business
     and affairs of Employer; use his best efforts, skills and abilities to
     promote the interests of Employer; and faithfully perform the duties
     described herein and such other executive duties as the Employer's Board of
     Directors shall assign to him from time to time.

     3.   Covenant.  Employee covenants and agrees that during the term of this
     Agreement, he will not, directly or indirectly, either as owner, partner,
     stockholder, broker, dealer, agent, employee or otherwise, engage in any
     other business activity for gain or profit or other pecuniary advantage;
     provided, however, that this paragraph shall not limit or restrict
     Employee's rights to serve on the boards of directors of noncompeting
     companies or to make and have personal investments in such form or manner
     as will not require his active services in the daily operations of the
     businesses in which such investments are made.

                                       2

     4.   Compensation.

          (a)  Employer shall pay Employee, and Employee hereby agrees to
     accept, as partial compensation for all services rendered hereunder, an
     annual salary of not less than $144,000, payable in semi-monthly
     installments and subject to such deductions and withholdings as are
     required to be made pursuant to applicable governmental laws, rules and
     regulations.

          (b)  Employee shall be entitled to management incentive compensation
     in an amount equivalent to THIRTY-FIVE PERCENT (35%) of his annual salary,
     subject to the criteria detailed in the provisions of Employer's Management
     Incentive Compensation Plan.

          (c)  Employer shall also provide Employee with such health care
     benefits, disability insurance and term life insurance as Employer provides
     for its executive employees generally in amounts determined by and
     appropriately adjusted for his compensation, length of service and other
     such relevant criteria, subject to Employee's satisfaction of any
     eligibility criteria for such insurance.

          (d)  Employee shall be entitled to annual vacation time of four (4)
     weeks duration (unless under Employer's vacation policy, he is entitled to
     additional vacation time because of his length of service with the
     Company), during which time his compensation shall be paid in full.

          (e)  Employee shall be entitled to benefits under Employer's
     Retirement Plan, as amended, Supplemental Executive Retirement Plan, as
     amended, and the Post-Retirement Medical Insurance Plan in amounts
     determined by and appropriately adjusted for compensation, length of
     service and other such relevant criteria.

     5.   Expenses.  Employer agrees to pay or reimburse Employee for all
     reasonable travel and other expenses incurred by Employee in connection
     with the performance of his services under this Agreement, upon
     presentation of such reasonably detailed expense statements, vouchers or
     other supporting information, as it may from time to time request.

     6.   Confidentiality.  Employee recognizes and acknowledges that during his
     employment by Employer pursuant to this Agreement he may have access to or
     may obtain information of a secret, special and unique value to Employer
     concerning customers, customer lists, processes, technologies, products,
     formulas, devices, designs, inventions, discoveries, plans, strategies and
     methods of operation (collectively and individually "Confidential
     Information").  Employee further recognizes and acknowledges that all

                                       3
<PAGE>
 
     Confidential Information which is now or may hereafter be in his possession
     is the property of Employer and that protection of this Confidential
     Information against unauthorized disclosure or use is of critical
     importance to Employer in order to protect Employer from unfair
     competition.  Employee therefore agrees that he will not at any time,
     either while employed by Employer or afterwards, without the prior written
     consent of the Board of Directors of Employer, make any independent use of
     such Confidential Information, or knowingly disclose the same, directly or
     indirectly, to any other person, firm, corporation or other entity, for any
     reason or purpose whatsoever, except to professional advisors of Employer
     or others who have a business relationship with Employer and who, in
     Employee's judgment, have a business need to know (e.g. advisory board
     members), and except on advice of counsel during testimony under subpoena
     in any court or before any administrative agency having jurisdiction or
     during any authorized governmental inquiry or investigation, provided that
     Employee shall cooperate with Employer in taking all reasonable and
     appropriate steps to assure the protection of such Confidential Information
     from unauthorized use or disclosure outside of such action, proceeding,
     inquiry or investigation, or except to the extent that any such
     Confidential Information shall be in the public domain other than by reason
     of Employee's breach of this Paragraph 6.

     7.   Ideas and Inventions.  Employee shall disclose promptly and thereafter
     turn over to Employer any and all concepts and ideas for inventions,
     improvements, programs, systems, novel techniques, copyrightable materials
     and other valuable discoveries, whether patentable or not, which are
     conceived or made by Employee solely or jointly with another during the
     period of employment, on the time or property of Employer or otherwise, and
     which are related to the business or activities of Employer or which
     Employee conceives as a result of his employment by Employer.  Employee
     hereby assigns and agrees to assign to Employer or its nominee all his
     interests in any of the foregoing.  Whenever requested to do so by
     Employer, Employee shall execute any and all patent applications,
     assignments or other transfer instruments which Employer shall deem
     necessary to apply for and obtain Letters of Patent of the United States or
     any foreign country or other applicable trade secret protection or to
     otherwise confirm and protect Employer's interest in and ownership of all
     such inventions, improvements, programs, systems, novel techniques,
     copyrightable materials and other discoveries.

     8.   Restrictive Covenant.  Employee acknowledges that he is a key
     executive and that the services to be rendered hereunder are of a critical
     nature to the continued success of Employer. In view of the value to
     Employer of the

                                       4
<PAGE>
 
     services of Employee for which Employer has contracted hereunder, and in
     recognition of Employer's obligations hereunder, Employee covenants and
     agrees as follows:

          (a)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, solicit business for any person, firm or entity
     engaged primarily in developing, manufacturing and marketing medical or
     dental sterility assurance systems and examining and operatory equipment,
     or in any other business in which Employer, from time to time, shall be
     engaged in those cities or counties of the United States in which Employer
     shall then be transacting business, from any client, customer or account of
     Employer, or attempt to convert said persons or entities to other methods
     of using the same or similar products or services as provided by Employer.
     Not-withstanding the foregoing, in the event of a "change in control", as
     defined in Paragraph 1 hereof, the foregoing restriction shall apply only
     with respect to the business in which MDT Corporation is engaged, the
     cities or counties of the United States in which MDT Corporation transacted
     business and the products or services provided by MDT Corporation
     immediately prior to such change in control.

          (b)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, engage in developing, manufacturing and marketing
     medical or dental sterility assurance systems and examining and operatory
     equipment or in any other business in which Employer, from time to time,
     shall be engaged, in those cities or counties of the United States in which
     Employer shall then be transacting business.   Notwithstanding the
     foregoing in the event of a "change in control", as defined in Paragraph 1
     hereof, the foregoing restriction shall apply only with respect to the
     business in which MDT Corporation is engaged and the cities or counties of
     the United States in which MDT Corporation transacted business and the
     products or services provided by MDT Corporation immediately prior to such
     change in control.

          (c)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, solicit for employment or employ any employee of
     Employer.

                                       5
<PAGE>
 
          (d)  Subparagraphs (a), (b) and (c) shall not apply in the event the
     Employee resigns within one year following a "change in control", as
     defined in Paragraph 1 hereof, that was not previously approved by the
     Board of Directors of Employer.

     As used herein, the term transacting business within "those cities and
     counties" includes the carrying on of a business which may be located
     elsewhere but which involves sales or any activity within the stipulated
     city or county.  The covenants contained in this paragraph shall be deemed
     to be a series of separate covenants, for each city and county of each
     state where Employer is carrying on such business.  If in any judicial
     proceeding a court shall refuse to enforce all of the separate covenants
     deemed included in such action, then such unenforceable covenants shall be
     deemed eliminated from the provisions hereof for the purposes of such
     proceedings to the extent necessary to permit the remaining separate
     covenants to be enforced in such proceedings.

     9.   Relief.  It is recognized that in the event of Employee's breach of
     Paragraphs 6, 7, or 8, the damages resulting from such breach would be
     difficult, if not impossible to ascertain, and that Employer would be
     subject to irreparable injury therefrom.  It is, therefore, agreed that
     Employer, in addition to and without limiting any other remedy or right it
     may have, shall be entitled to such equitable and injunctive relief as may
     be available to restrain Employee from violation of any of said covenants,
     such right to injunctive and equitable relief, however, to be cumulative
     and in addition to whatever other remedies Employer may have in the
     premises, including the recovery of consequential but not punitive damages
     from Employee.

     10.  Termination.

          (a)  This Agreement and the employment of Employee hereunder shall
     terminate upon the occurrence of the first to occur of the following events
     or conditions:

               (i)  the expiration of the term specified in Paragraph 1 hereof.

              (ii)  the death of Employee.

             (iii)  the incapacity of Employee for a period of six consecutive
     months to perform his duties hereunder.

              (iv)  the election of the Board of Directors of Employer to
     terminate Employee's employment for "cause", which shall mean a
     determination by the Board of Directors of Employer in the exercise of its
     sole discretion, that

                                       6
<PAGE>
 
     there has been fraud, misappropriation, embezzlement, gross and continuing
     inattention to duty, or a substantial breach of this Agreement by Employee.

               (v)  the election of the Board of Directors of Employer to
     terminate Employee's employment upon the entry of any final non appealable
     order for relief in respect of Employee under any bankruptcy,
     reorganization, arrangement, insolvency, readjustment of debt or similar
     law of any jurisdiction now or hereafter in effect if, in the good faith
     determination of the Board of Directors, such entry of a final, non
     appealable order for relief resulted from the willful neglect, financial
     irresponsibility or moral turpitude of Employee.

              (vi)  Employee's conviction of a crime involving moral turpitude.

          (b)  Any termination of this Agreement pursuant to clauses (i) or (ii)
     of Subparagraph (a) of this Paragraph 10 shall be effective on the
     expiration date of this Agreement or the date of death, as the case may be.
     Any termination pursuant to clauses (iii), (iv), (v) or (vi) of
     Subparagraph (a) of this Paragraph 10 shall be effective immediately upon
     delivery of notice of termination to Employee.

          (c)  Upon the expiration or earlier termination of this Agreement by
     Employee or by Employer pursuant to Subparagraph (a) of this Paragraph 10,
     other than in connection with a "change in control", as such term is
     defined in Paragraph 1 of this Agreement, Employer's sole obligation shall
     be to pay Employee or his estate any compensation remaining unpaid through
     the effective date of termination. In the case of the death of Employee,
     however, Employer's obligation shall be to pay Employee's designated
     beneficiary or estate the Employee's salary in effect at the time of his
     death, in semi-monthly installments, and to provide Employee's designated
     beneficiary healthcare benefits on the same basis as an active employee for
     180 days; to pay the management incentive compensation to which the
     Employee would otherwise have been entitled for the fiscal year in which
     death occurs; and to pay to his designated beneficiary or estate the life
     insurance, retirement and supplementary retirement benefits to which they
     are entitled within 180 days.  Upon the termination of this Agreement by
     Employer without cause, other than in connection with a "change in
     control," as such term is defined in Paragraph 1 of this Agreement, and as
     the sole and exclusive remedy against Employer for the exercise of its
     right under this Agreement to terminate this Agreement without cause,
     Employer's sole obligation shall be to pay Employee the salary in effect at
     the time of his termination, in semi-monthly installments, to continue his

                                       7
<PAGE>
 
     participation in the Management Incentive Compensation Plan, to provide
     healthcare and life insurance benefits and to continue his participation in
     the Retirement Plan, as amended, and the Supplemental Executive Retirement
     Plan, as amended, on the same basis as an active employee for the remaining
     term of this Agreement, without any further extensions of such term;
     provided, however, that the amount  of salary shall be reduced by the
     salary Employee earns from reasonably comparable employment with another
     employer; and provided further that Employer's obligation to continue
     healthcare and life insurance benefits shall end when Employee is covered
     under reasonably comparable benefit plans provided by another employer.
     Upon the termination of this Agreement by Employer without cause in
     connection with a "change in control," as such term is defined in Paragraph
     1 of this Agreement, and as the sole and exclusive remedy against Employer
     for the exercise of its right under this Agreement to terminate this
     Agreement without cause, Employer's sole obligation shall be to pay
     Employee a lump sum, undiscounted cash payment equal to the compensation
     payable through the remaining term of this Agreement, as such term was
     reinstated under Paragraph 1,  to continue his participation in the
     Management Incentive Compensation Plan, to provide healthcare and life
     insurance benefits and to continue his participation in the Retirement
     Plan, as amended, and the Supplemental Executive Retirement Plan, as
     amended, on the same basis as an active employee for the remaining term of
     this Agreement, as such term was reinstated under Paragraph 1, without any
     further extensions of such term; provided, however, that Employer's
     obligation to continue healthcare and life insurance benefits shall end
     when Employee is covered under reasonably comparable benefit plans provided
     by another employer.  The resignation of Employee in response to a demand
     by Employer for the relocation of Employee outside of the United States
     shall be deemed a termination by Employer without cause for purposes of
     this Agreement.

          (d)  The respective rights and obligations of Employer and Employee
     pursuant to Paragraphs 6, 7, 8 and 9 hereof, shall survive the expiration
     or earlier termination of this Agreement.

     11.  Bonding.  Employer may apply for and maintain fidelity bonds or
     similar insurance with respect to the acts and omissions of Employee.
     Employee agrees to take such steps and perform such acts as shall be
     necessary to assist Employer in obtaining or maintaining in effect such
     bonds or insurance, including the completion of the required applications
     and questionnaires, the furnishing of  any  required references, and
     consenting, upon request, to any required background, financial or other
     investigations.  Any such required information will be treated as
     confidential

                                       8

     and will be returned promptly after the completion of such investigations.

     12.  Persons Bound.  This Agreement shall inure to the benefit of and be
     binding upon Employee, his legal representatives and testate or intestate
     distributees, and Employer, its successors and assigns.  This Agreement may
     not be assigned by Employee.

     13.  Notices.  Any notice or request required or permitted under this
     Agreement shall be in writing and given or made by hand delivery or
     registered or certified mail, return receipt requested, addressed to
     Employer or to Employee at Employer's then principal place of business,
     with a copy to Employee at his home address, as set forth on the records of
     Employer, or to either party hereto at such other address or addresses as
     such party may from time to time specify for the purpose in a notice
     similarly given to the other party.

     14.  No Waiver or Modification.  The waiver of the breach of any term or
     condition of this Agreement shall not be deemed to constitute the waiver of
     any other or subsequent breach of the same of any other term or condition.
     No amendment or modification of this Agreement shall be valid or binding
     unless made in writing and signed by the other party against whom such
     waiver or modification is to be enforced.

     15.  Governing Law.  This Agreement shall be construed and enforced in
     accordance with the laws of the State of Delaware applicable to agreements
     made and to be performed in said State.

     16.  Disputes.  In the event that any suit or other proceeding shall be
     brought by Employer or Employee in respect of an alleged breach by or
     default in the performance of the other party hereto, the successful party
     in such suit or proceeding (on the merits or otherwise) shall be entitled
     to reimbursement of all reasonable expenses and charges incurred by it or
     him in connection with the defense or prosecution of such suit or
     proceeding, including but not limited to the reasonable fees and expenses
     of counsel retained by such party.

     17.  Entire Agreement.  This Agreement represents the entire agreement of
     the parties hereto with respect to the subject matter hereof, and
     supersedes all prior agreements between Employer and Employee.  No
     representation, condition, provision or term related to or connected with
     this Agreement exists except as specifically set forth herein.

     18.  Employee's Warranty.  Employee represents and warrants to Employer
     that he is not bound by any agreement or subject

                                       9
<PAGE>
 
     to any restriction which would interfere with or prevent his entering into
     and carrying out this Agreement.

     19.  Severability.  The invalidity of all or any part of any paragraph or
     subparagraph of this Agreement shall not render invalid the remainder of
     this Agreement or of any such paragraph or subparagraph.

IN WITNESS WHEREOF, Employer and Employee have executed this Agreement as of the
date first written above.

                             EMPLOYMENT AGREEMENT


     THIS EMPLOYMENT AGREEMENT (this "Agreement") dated as of APRIL 1, 1995, is
between MDT BIOLOGIC COMPANY, a Delaware corporation ("Employer") and MICHAEL L.
SCHNEIER ("Employee").

     WHEREAS, Employer and Employee desire to enter into an agreement setting
forth the terms and conditions upon which Employee shall be employed by
Employer;


                                  WITNESSETH:


     That in consideration of the mutual covenants and obligations hereinafter
set forth, the parties hereto agree as follows:

     1.   Employment and Term.

          (a)  Employer hereby employs Employee and Employee hereby accepts
     employment with and agrees to serve Employer, in the capacities and subject
     to and upon the terms and conditions  hereinafter set forth.

          (b)  The term of Employee's employment hereunder shall be the three-
     year period commencing on APRIL 1, 1995 and ending on MARCH 31, 1998,
     subject to termination as provided in Paragraph 10 hereof.  Notwithstanding
     the foregoing, (i) on the second anniversary of this Agreement, the term
     hereof shall automatically be extended for an additional year, and (ii)
     thereafter, when only one year of the term, as extended pursuant to clause
     (i) or (ii) hereof, shall remain, the term hereof shall again be extended
     for an additional year, such extensions continuing from year to year in the
     same manner; provided, however, in each case that the term shall not be
     extended, if prior to the date of such extension, Employer's Board of
     Directors gives notice to Employee or Employee gives notice to Employer's
     Board of Directors that the term shall not be so extended.

          (c)  Upon the occurrence of a change in control, as hereinafter
     defined, notwithstanding the portion of the term hereof otherwise remaining
     outstanding, the term hereof shall automatically be reinstated as a period
     of three years, commencing upon the date of such change in control. A
     "change in control" for purposes of the preceding sentence shall mean (i)
     without prior approval of the Board of Directors of Employer, a single
     entity or group of affiliated entities acquires more than 50% of the voting
     stock of Employer issued and outstanding immediately prior to such
     acquisition; (ii) the Board of Directors of Employer

                                       1
<PAGE>
 
     approves an unsolicited bid by a single entity or group of affiliated
     entities to acquire more than 50% of the voting stock of Employer issued
     and outstanding immediately prior to the approval of such acquisition, and
     such acquisition is consummated; (iii) the stockholders of Employer approve
     the consummation of any merger of Employer or any sale or other disposition
     of all or substantially all of its assets, if the stockholders of Employer
     immediately before such transaction own, immediately after consummation of
     such transaction, equity securities (other than options and other rights to
     acquire equity securities) possessing less than 50% of the voting power of
     the surviving or acquiring corporation; or (iv) a change in the majority of
     the Board of Directors of Employer during any 24-month period without the
     approval of a majority of directors in office at the beginning of such
     period.

     2.   Duties.

          (a)  Employer agrees to employ Employee as VICE PRESIDENT, RESEARCH,
     DEVELOPMENT AND COMPLIANCE with responsibility for the duties normally
     associated with such executive position, and for such other executive
     duties as the Employer's Board of Directors shall assign to him from time
     to time, subject at all times to the direction of Employer's Board of
     Directors.

          (b)  Employee agrees that so long as this Agreement continues in
     effect, he shall devote his full business time and energies to the business
     and affairs of Employer; use his best efforts, skills and abilities to
     promote the interests of Employer; and faithfully perform the duties
     described herein and such other executive duties as the Employer's Board of
     Directors shall assign to him from time to time.

     3.   Covenant.  Employee covenants and agrees that during the term of this
     Agreement, he will not, directly or indirectly, either as owner, partner,
     stockholder, broker, dealer, agent, employee or otherwise, engage in any
     other business activity for gain or profit or other pecuniary advantage;
     provided, however, that this paragraph shall not limit or restrict
     Employee's rights to serve on the boards of directors of noncompeting
     companies or to make and have personal investments in such form or manner
     as will not require his active services in the daily operations of the
     businesses in which such investments are made.

     4.   Compensation.

          (a)  Employer shall pay Employee, and Employee hereby agrees to
     accept, as partial compensation for all services rendered hereunder, an
     annual salary of not less than

                                       2
<PAGE>
 
     $112,294, payable in semi-monthly installments and subject to such
     deductions and withholdings as are required to be made pursuant to
     applicable governmental laws, rules and regulations.

          (b)  Employee shall be entitled to management incentive compensation
     in an amount equivalent to TWENTY-FIVE PERCENT (25%) of his annual salary,
     subject to the criteria detailed in the provisions of Employer's Management
     Incentive Compensation Plan.

          (c)  Employer shall also provide Employee with such health care
     benefits, disability insurance and term life insurance as Employer provides
     for its executive employees generally in amounts determined by and
     appropriately adjusted for his compensation, length of service and other
     such relevant criteria, subject to Employee's satisfaction of any
     eligibility criteria for such insurance.

          (d)  Employee shall be entitled to annual vacation time of four (4)
     weeks duration (unless under Employer's vacation policy, he is entitled to
     additional vacation time because of his length of service with the
     Company), during which time his compensation shall be paid in full.

          (e)  Employee shall be entitled to benefits under Employer's
     Retirement Plan, as amended, Supplemental Executive Retirement Plan, as
     amended, and the Post-Retirement Medical Insurance Plan in amounts
     determined by and appropriately adjusted for compensation, length of
     service and other such relevant criteria.

     5.   Expenses.  Employer agrees to pay or reimburse Employee for all
     reasonable travel and other expenses incurred by Employee in connection
     with the performance of his services under this Agreement, upon
     presentation of such reasonably detailed expense statements, vouchers or
     other supporting information, as it may from time to time request.

     6.   Confidentiality.  Employee recognizes and acknowledges that during his
     employment by Employer pursuant to this Agreement he may have access to or
     may obtain information of a secret, special and unique value to Employer
     concerning customers, customer lists, processes, technologies, products,
     formulas, devices, designs, inventions, discoveries, plans, strategies and
     methods of operation (collectively and individually "Confidential
     Information").  Employee further recognizes and acknowledges that all
     Confidential Information which is now or may hereafter be in his possession
     is the property of Employer and that protection of this Confidential
     Information against unauthorized disclosure or use is of critical
     importance to Employer in order to protect Employer from unfair

                                       3
<PAGE>
 
     competition.  Employee therefore agrees that he will not at any time,
     either while employed by Employer or afterwards, without the prior written
     consent of the Board of Directors of Employer, make any independent use of
     such Confidential Information, or knowingly disclose the same, directly or
     indirectly, to any other person, firm, corporation or other entity, for any
     reason or purpose whatsoever, except to professional advisors of Employer
     or others who have a business relationship with Employer and who, in
     Employee's judgment, have a business need to know (e.g. advisory board
     members), and except on advice of counsel during testimony under subpoena
     in any court or before any administrative agency having jurisdiction or
     during any authorized governmental inquiry or investigation, provided that
     Employee shall cooperate with Employer in taking all reasonable and
     appropriate steps to assure the protection of such Confidential Information
     from unauthorized use or disclosure outside of such action, proceeding,
     inquiry or investigation, or except to the extent that any such
     Confidential Information shall be in the public domain other than by reason
     of Employee's breach of this Paragraph 6.

     7.  Ideas and Inventions.  Employee shall disclose promptly and thereafter
     turn over to Employer any and all concepts and ideas for inventions,
     improvements, programs, systems, novel techniques, copyrightable materials
     and other valuable discoveries, whether patentable or not, which are
     conceived or made by Employee solely or jointly with another during the
     period of employment, on the time or property of Employer or otherwise, and
     which are related to the business or activities of Employer or which
     Employee conceives as a result of his employment by Employer.  Employee
     hereby assigns and agrees to assign to Employer or its nominee all his
     interests in any of the foregoing.  Whenever requested to do so by
     Employer, Employee shall execute any and all patent applications,
     assignments or other transfer instruments which Employer shall deem
     necessary to apply for and obtain Letters of Patent of the United States or
     any foreign country or other applicable trade secret protection or to
     otherwise confirm and protect Employer's interest in and ownership of all
     such inventions, improvements, programs, systems, novel techniques,
     copyrightable materials and other discoveries.

     8.   Restrictive Covenant.  Employee acknowledges that he is a key
     executive and that the services to be rendered hereunder are of a critical
     nature to the continued success of Employer. In view of the value to
     Employer of the services of Employee for which Employer has contracted
     hereunder, and in recognition of Employer's obligations hereunder, Employee
     covenants and agrees as follows:

                                       4
<PAGE>
 
          (a)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, solicit business for any person, firm or entity
     engaged primarily in developing, manufacturing and marketing medical or
     dental sterility assurance systems and examining and operatory equipment,
     or in any other business in which Employer, from time to time, shall be
     engaged in those cities or counties of the United States in which Employer
     shall then be transacting business, from any client, customer or account of
     Employer, or attempt to convert said persons or entities to other methods
     of using the same or similar products or services as provided by Employer.
     Not-withstanding the foregoing, in the event of a "change in control", as
     defined in Paragraph 1 hereof, the foregoing restriction shall apply only
     with respect to the business in which MDT Corporation is engaged, the
     cities or counties of the United States in which MDT Corporation transacted
     business and the products or services provided by MDT Corporation
     immediately prior to such change in control.

          (b)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, engage in developing, manufacturing and marketing
     medical or dental sterility assurance systems and examining and operatory
     equipment or in any other business in which Employer, from time to time,
     shall be engaged, in those cities or counties of the United States in which
     Employer shall then be transacting business.   Notwithstanding the
     foregoing in the event of a "change in control", as defined in Paragraph 1
     hereof, the foregoing restriction shall apply only with respect to the
     business in which MDT Corporation is engaged and the cities or counties of
     the United States in which MDT Corporation transacted business and the
     products or services provided by MDT Corporation immediately prior to such
     change in control.

          (c)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, solicit for employment or employ any employee of
     Employer.

          (d)  Subparagraphs (a), (b) and (c) shall not apply in the event the
     Employee resigns within one year following a "change in control", as
     defined in Paragraph 1 hereof, that was not previously approved by the
     Board of Directors of Employer.

                                       5
<PAGE>
 
     As used herein, the term transacting business within "those cities and
     counties" includes the carrying on of a business which may be located
     elsewhere but which involves sales or any activity within the stipulated
     city or county.  The covenants contained in this paragraph shall be deemed
     to be a series of separate covenants, for each city and county of each
     state where Employer is carrying on such business.  If in any judicial
     proceeding a court shall refuse to enforce all of the separate covenants
     deemed included in such action, then such unenforceable covenants shall be
     deemed eliminated from the provisions hereof for the purposes of such
     proceedings to the extent necessary to permit the remaining separate
     covenants to be enforced in such proceedings.

     9.   Relief.  It is recognized that in the event of Employee's breach of
     Paragraphs 6, 7, or 8, the damages resulting from such breach would be
     difficult, if not impossible to ascertain, and that Employer would be
     subject to irreparable injury therefrom.  It is, therefore, agreed that
     Employer, in addition to and without limiting any other remedy or right it
     may have, shall be entitled to such equitable and injunctive relief as may
     be available to restrain Employee from violation of any of said covenants,
     such right to injunctive and equitable relief, however, to be cumulative
     and in addition to whatever other remedies Employer may have in the
     premises, including the recovery of consequential but not punitive damages
     from Employee.

     10.  Termination.

          (a)  This Agreement and the employment of Employee hereunder shall
     terminate upon the occurrence of the first to occur of the following events
     or conditions:

               (i)  the expiration of the term specified in Paragraph 1
     hereof.

              (ii)  the death of Employee.

             (iii)  the incapacity of Employee for a period of six consecutive
     months to perform his duties hereunder.

              (iv)  the election of the Board of Directors of Employer to
     terminate Employee's employment for "cause", which shall mean a
     determination by the Board of Directors of Employer in the exercise of its
     sole discretion, that there has been fraud, misappropriation, embezzlement,
     gross and continuing inattention to duty, or a substantial breach of this
     Agreement by Employee.

               (v)  the election of the Board of Directors of Employer to
     terminate Employee's employment upon the entry

                                       6
<PAGE>
 
     of any final non appealable order for relief in respect of Employee under
     any bankruptcy, reorganization, arrangement, insolvency, readjustment of
     debt or similar law of any jurisdiction now or hereafter in effect if, in
     the good faith determination of the Board of Directors, such entry of a
     final, non appealable order for relief resulted from the willful neglect,
     financial irresponsibility or moral turpitude of Employee.

              (vi)  Employee's conviction of a crime involving moral turpitude.

          (b)  Any termination of this Agreement pursuant to clauses (i) or (ii)
     of Subparagraph (a) of this Paragraph 10 shall be effective on the
     expiration date of this Agreement or the date of death, as the case may be.
     Any termination pursuant to clauses (iii), (iv), (v) or (vi) of
     Subparagraph (a) of this Paragraph 10 shall be effective immediately upon
     delivery of notice of termination to Employee.

          (c)  Upon the expiration or earlier termination of this Agreement by
     Employee or by Employer pursuant to Subparagraph (a) of this Paragraph 10,
     other than in connection with a "change in control", as such term is
     defined in Paragraph 1 of this Agreement, Employer's sole obligation shall
     be to pay Employee or his estate any compensation remaining unpaid through
     the effective date of termination. In the case of the death of Employee,
     however, Employer's obligation shall be to pay Employee's designated
     beneficiary or estate the Employee's salary in effect at the time of his
     death, in semi-monthly installments, and to provide Employee's designated
     beneficiary healthcare benefits on the same basis as an active employee for
     180 days; to pay the management incentive compensation to which the
     Employee would otherwise have been entitled for the fiscal year in which
     death occurs; and to pay to his designated beneficiary or estate the life
     insurance, retirement and supplementary retirement benefits to which they
     are entitled within 180 days.  Upon the termination of this Agreement by
     Employer without cause, other than in connection with a "change in
     control," as such term is defined in Paragraph 1 of this Agreement, and as
     the sole and exclusive remedy against Employer for the exercise of its
     right under this Agreement to terminate this Agreement without cause,
     Employer's sole obligation shall be to pay Employee the salary in effect at
     the time of his termination, in semi-monthly installments, to continue his
     participation in the Management Incentive Compensation Plan, to provide
     healthcare and life insurance benefits and to continue his participation in
     the Retirement Plan, as amended, and the Supplemental Executive Retirement
     Plan, as amended, on the same basis as an active employee for the remaining
     term of this Agreement, without any further

                                       7
<PAGE>
 
     extensions of such term; provided, however, that the amount  of salary
     shall be reduced by the salary Employee earns from reasonably comparable
     employment with another employer; and provided further that Employer's
     obligation to continue healthcare and life insurance benefits shall end
     when Employee is covered under reasonably comparable benefit plans provided
     by another employer.  Upon the termination of this Agreement by Employer
     without cause in connection with a "change in control," as such term is
     defined in Paragraph 1 of this Agreement, and as the sole and exclusive
     remedy against Employer for the exercise of its right under this Agreement
     to terminate this Agreement without cause, Employer's sole obligation shall
     be to pay Employee a lump sum, undiscounted cash payment equal to the
     compensation payable through the remaining term of this Agreement, as such
     term was reinstated under Paragraph 1,  to continue his participation in
     the Management Incentive Compensation Plan, to provide healthcare and life
     insurance benefits and to continue his participation in the Retirement
     Plan, as amended, and the Supplemental Executive Retirement Plan, as
     amended, on the same basis as an active employee for the remaining term of
     this Agreement, as such term was reinstated under Paragraph 1, without any
     further extensions of such term; provided, however, that Employer's
     obligation to continue healthcare and life insurance benefits shall end
     when Employee is covered under reasonably comparable benefit plans provided
     by another employer.  The resignation of Employee in response to a demand
     by Employer for the relocation of Employee outside of the United States
     shall be deemed a termination by Employer without cause for purposes of
     this Agreement.

          (d)  The respective rights and obligations of Employer and Employee
     pursuant to Paragraphs 6, 7, 8 and 9 hereof, shall survive the expiration
     or earlier termination of this Agreement.

     11.  Bonding.  Employer may apply for and maintain fidelity bonds or
     similar insurance with respect to the acts and omissions of Employee.
     Employee agrees to take such steps and perform such acts as shall be
     necessary to assist Employer in obtaining or maintaining in effect such
     bonds or insurance, including the completion of the required applications
     and questionnaires, the furnishing of  any  required references, and

                              EMPLOYMENT AGREEMENT



          THIS EMPLOYMENT AGREEMENT (this "Agreement") dated as of APRIL 1,
1995, is between MDT DIAGNOSTIC COMPANY, a Delaware corporation ("Employer") and
CHARLES B. SWENSON ("Employee").

          WHEREAS, Employer and Employee desire to enter into an agreement
setting forth the terms and conditions upon which Employee shall be employed by
Employer;


                                  WITNESSETH:


          That in consideration of the mutual covenants and obliga tions
hereinafter set forth, the parties hereto agree as follows:

          1.   Employment and Term.

               (a)  Employer hereby employs Employee and Employee hereby accepts
     employment with and agrees to serve Employer, in the capacities and subject
     to and upon the terms and conditions hereinafter set forth.

               (b)  The term of Employee's employment hereunder shall be the
     four-year period commencing on APRIL 1, 1995 and ending on MARCH 31, 1999,
     subject to termination as provided in Paragraph 10 hereof.  Notwithstanding
     the foregoing, (i) on the second anniversary of this Agreement, the term
     hereof shall automatically be extended for an additional year, and (ii)
     thereafter, when only two years of the term, as extended pursuant to clause
     (i) or (ii) hereof, shall remain, the term hereof shall again be extended
     for an additional year, such extensions continuing from year to year in the
     same manner; provided, however, in each case that the term shall not be
     extended, if prior to the date of such extension, Employer's Board of
     Directors gives notice to Employee or Employee gives notice to Employer's
     Board of Directors that the term shall not be so extended.

               (c)  Upon the occurrence of a change in control, as hereinafter
     defined, notwithstanding the portion of the term hereof otherwise remaining
     outstanding, the term hereof shall automatically be reinstated as a period
     of four years, commencing upon the date of such change in control.  A
     "change in control" for purposes of the preceding sentence shall mean (i)
     without prior approval of the Board of Directors of Employer, a single
     entity or group of affiliated entities acquires more than 50% of the voting
     stock of Employer issued and outstanding immediately prior to such
     acquisition; (ii) the Board of Directors of Employer approves an
     unsolicited bid
<PAGE>
 
     by a single entity or group of affiliated entities to acquire more than 50%
     of the voting stock of Employer issued and outstanding immediately prior to
     the approval of such acquisition, and such acquisition is consummated;
     (iii) the stockholders of Employer approve the consummation of any merger
     of Employer or any sale or other disposition of all or substantially all of
     its assets, if the stockholders of Employer immediately before such
     transaction own, immediately after consummation of such transaction, equity
     securities (other than options and other rights to acquire equity
     securities) possessing less than 50% of the voting power of the surviving
     or acquiring corporation; or (iv) a change in the majority of the Board of
     Directors of Employer during any 24-month period without the approval of a
     majority of directors in office at the beginning of such period.

               (d)  Upon the sale or divestiture of MDT Diagnostic Company,
     notwithstanding the portion of the term hereof otherwise remaining
     outstanding, the term hereof shall automatically be reinstated as a period
     of four years, commencing upon the date of such sale or divestiture.

          2.   Duties.
 
               (a)  Employer agrees to employ Employee as PRESIDENT with
     responsibility for the duties normally associated with such executive
     position, and for such other executive duties as the Employer's Board of
     Directors shall assign to him from time to time, subject at all times to
     the direction of Employer's Board of Directors.

               (b)  Employee agrees that so long as this Agreement continues in
     effect, he shall devote his full business time and energies to the business
     and affairs of Employer; use his best efforts, skills and abilities to
     promote the interests of Employer; and faithfully perform the duties
     described herein and such other executive duties as the Employer's Board of
     Directors shall assign to him from time to time.

          3.   Covenant.  Employee covenants and agrees that during the term of
this Agreement, he will not, directly or indirectly, either as owner, partner,
stockholder, broker, dealer, agent, employee or otherwise, engage in any other
business activity for gain or profit or other pecuniary advantage; provided,
however, that this paragraph shall not limit or restrict Employee's rights to
serve on the boards of directors of noncompeting companies or to make and have
personal investments in such form or manner as will not require his active
services in the daily operations of the businesses in which such investments are
made.

                                       2

          4.   Compensation.

               (a)  Employer shall pay Employee, and Employee hereby agrees to
     accept, as partial compensation for all services rendered hereunder, an
     annual salary of not less than $144,000, payable in semi-monthly
     installments and subject to such deductions and withholdings as are
     required to be made pursuant to applicable governmental laws, rules and
     regulations.

               (b)  Employee shall be entitled to management incentive
     compensation in an amount equivalent to THIRTY-FIVE PERCENT (35%) of his
     annual salary, subject to the criteria detailed in the provisions of
     Employer's Management Incentive Compensation Plan.

               (c)  Employer shall also provide Employee with such health care
     benefits, disability insurance and term life insurance as Employer provides
     for its executive employees generally in amounts determined by and
     appropriately adjusted for his compensation, length of service and other
     such relevant criteria, subject to Employee's satisfaction of any
     eligibility criteria for such insurance.

               (d)  Employee shall be entitled to annual vacation time of four
     (4) weeks duration (unless under Employer's vacation policy, he is entitled
     to additional vacation time because of his length of service with the
     Company), during which time his compensation shall be paid in full.

               (e)  Employee shall be entitled to benefits under Employer's
     Retirement Plan, as amended, Supplemental Executive Retirement Plan, as
     amended, and the Post-Retirement Medical Insurance Plan in amounts
     determined by and appropriately adjusted for compensation, length of
     service and other such relevant criteria.

          5.   Expenses.  Employer agrees to pay or reimburse Employee for all
reasonable travel and other expenses incurred by Employee in connection with the
performance of his services under this Agreement, upon presentation of such
reasonably detailed expense statements, vouchers or other supporting
information, as it may from time to time request.

          6.   Confidentiality.  Employee recognizes and acknowledges that
during his employment by Employer pursuant to this Agreement he may have access
to or may obtain information of a secret, special and unique value to Employer
concerning customers, customer lists, processes, technologies, products,
formulas, devices, designs, inventions, discoveries, plans, strategies and
methods of operation (collectively and individually "Confidential Information").
Employee further recognizes and acknowledges that all Confidential Information
which is now or may

                                       3
<PAGE>
 
hereafter be in his possession is the property of Employer and that protection
of this Confidential Information against unauthorized disclosure or use is of
critical importance to Employer in order to protect Employer from unfair
competition.  Employee therefore agrees that he will not at any time, either
while employed by Employer or afterwards, without the prior written consent of
the Board of Directors of Employer, make any independent use of such
Confidential Information, or knowingly disclose the same, directly or
indirectly, to any other person, firm, corporation or other entity, for any
reason or purpose whatsoever, except to professional advisors of Employer or
others who have a business relationship with Employer and who, in Employee's
judgment, have a business need to know (e.g. advisory board members), and except
on advice of counsel during testimony under subpoena in any court or before any
administrative agency having jurisdiction or during any authorized governmental
inquiry or investigation, provided that Employee shall cooperate with Employer
in taking all reasonable and appropriate steps to assure the protection of such
Confidential Information from unauthorized use or disclosure outside of such
action, proceeding, inquiry or investigation, or except to the extent that any
such Confidential Information shall be in the public domain other than by reason
of Employee's breach of this Paragraph 6.

          7.   Ideas and Inventions.  Employee shall disclose promptly and
thereafter turn over to Employer any and all concepts and ideas for inventions,
improvements, programs, systems, novel techniques, copyrightable materials and
other valuable discoveries, whether patentable or not, which are conceived or
made by Employee solely or jointly with another during the period of employment,
on the time or property of Employer or otherwise, and which are related to the
business or activities of Employer or which Employee conceives as a result of
his employment by Employer.  Employee hereby assigns and agrees to assign to
Employer or its nominee all his interests in any of the foregoing.  Whenever
requested to do so by Employer, Employee shall execute any and all patent
applications, assignments or other transfer instruments which Employer shall
deem necessary to apply for and obtain Letters of Patent of the United States or
any foreign country or other applicable trade secret protection or to otherwise
confirm and protect Employer's interest in and ownership of all such inventions,
improvements, programs, systems, novel techniques, copyrightable materials and
other discoveries.

          8.   Restrictive Covenant.  Employee acknowledges that he is a key
executive and that the services to be rendered hereunder are of a critical
nature to the continued success of Employer.  In view of the value to Employer
of the services of Employee for which Employer has contracted hereunder, and in
recognition of Employer's obligations hereunder, Employee covenants and agrees
as follows:

               (a)  During Employee's employment hereunder, and for a period of
     two (2) years after he ceases to be employed by

                                       4
<PAGE>
 
     Employer by reason of Employee's resignation or termination for cause,
     Employee shall not, directly or indirectly, as employee, consultant,
     officer, director, partner, or stockholder, solicit business for any
     person, firm or entity engaged primarily in developing, manufacturing and
     marketing medical or dental sterility assurance systems and examining and
     operatory equipment, or in any other business in which Employer, from time
     to time, shall be engaged in those cities or counties of the United States
     in which Employer shall then be transacting business, from any client,
     customer or account of Employer, or attempt to convert said persons or
     entities to other methods of using the same or similar products or services
     as provided by Employer.  Notwithstanding the foregoing, in the event of a
     "change in control", as defined in Paragraph 1 hereof, the foregoing
     restriction shall apply only with respect to the business in which MDT
     Corporation is engaged, the cities or counties of the United States in
     which MDT Corporation transacted business and the products or services
     provided by MDT Corporation immediately prior to such change in control.

               (b)  During Employee's employment hereunder, and for a period of
     two (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stock holder, engage in developing, manufacturing and marketing
     medical or dental sterility assurance systems and examining and operatory
     equipment or in any other business in which Employer, from time to time,
     shall be engaged, in those cities or counties of the United States in which
     Employer shall then be transacting business.  Notwithstanding the foregoing
     in the event of a "change in control", as defined in Paragraph 1 hereof,
     the foregoing restriction shall apply only with respect to the business in
     which MDT Corporation is engaged and the cities or counties of the United
     States in which MDT Corporation transacted business and the products or
     services provided by MDT Corporation immediately prior to such change in
     control.

               (c)  During Employee's employment hereunder, and for a period of
     two (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, solicit for employment or employ any employee of
     Employer.

               (d)  Subparagraphs (a), (b) and (c) shall not apply in the event
     the Employee resigns within one year following a "change in control", as
     defined in Paragraph 1 hereof, that was not previously approved by the
     Board of Directors of Employer.

                                       5
<PAGE>
 
          As used herein, the term transacting business within "those cities and
counties" includes the carrying on of a business which may be located elsewhere
but which involves sales or any activity within the stipulated city or county.
The covenants contained in this paragraph shall be deemed to be a series of
separate covenants, for each city and county of each state where Employer is
carrying on such business.  If in any judicial proceeding a court shall refuse
to enforce all of the separate covenants deemed included in such action, then
such unenforceable covenants shall be deemed eliminated from the provisions
hereof for the purposes of such proceedings to the extent necessary to permit
the remaining separate covenants to be enforced in such proceedings.

          9.   Relief.  It is recognized that in the event of Employee's breach
of Paragraphs 6, 7, or 8, the damages resulting from such breach would be
difficult, if not impossible to ascertain, and that Employer would be subject to
irreparable injury therefrom.  It is, therefore, agreed that Employer, in
addition to and without limiting any other remedy or right it may have, shall be
entitled to such equitable and injunctive relief as may be available to restrain
Employee from violation of any of said covenants, such right to injunctive and
equitable relief, however, to be cumulative and in addition to whatever other
remedies Employer may have in the premises, including the recovery of
consequential but not punitive damages from Employee.

          10.  Termination.

               (a)  This Agreement and the employment of Employee hereunder
     shall terminate upon the occurrence of the first to occur of the following
     events or conditions:

                    (i)  the expiration of the term specified in Paragraph 1
          hereof.


                   (ii)  the death of Employee.

                  (iii)  the incapacity of Employee for a period of six
          consecutive months to perform his duties hereunder.

                   (iv)  the election of the Board of Directors of Employer to
          terminate Employee's employment for "cause", which shall mean a
          determination by the Board of Directors of Employer in the exercise of
          its sole discretion, that there has been fraud, misappropriation,
          embezzlement, gross and continuing inattention to duty, or a
          substantial breach of this Agreement by Employee.


                    (v)  the election of the Board of Directors of Employer to
          terminate Employee's employment upon the

                                       6
<PAGE>
 
          entry of any final non appealable order for relief in respect of
          Employee under any bankruptcy, reorganization, arrangement,
          insolvency, readjustment of debt or similar law of any jurisdiction
          now or hereafter in effect if, in the good faith determination of the
          Board of Directors, such entry of a final, non appealable order for
          relief resulted from the willful neglect, financial irresponsibility
          or moral turpitude of Employee.

                    (vi) Employee's conviction of a crime involving moral
          turpitude.

               (b)  Any termination of this Agreement pursuant to clauses (i) or
     (ii) of Subparagraph (a) of this Paragraph 10 shall be effective on the
     expiration date of this Agreement or the date of death, as the case may be.
     Any termination pursuant to clauses (iii), (iv), (v) or (vi) of
     Subparagraph (a) of this Paragraph 10 shall be effective immediately upon
     delivery of notice of termination to Employee.

               (c)  Upon the expiration or earlier termination of this Agreement
     by Employee or by Employer pursuant to Subparagraph (a) of this Paragraph
     10,  other than in connection with a "change in control", as such term is
     defined in Paragraph 1 of this Agreement, Employer's sole obligation shall
     be to pay Employee or his estate any compensation remaining unpaid through
     the effective date of termination.  In the case of the death of Employee,
     however, Employer's obligation shall be to pay Employee's designated
     beneficiary or estate the Employee's salary in effect at the time of his
     death, in semi-monthly installments, and to provide Employee's designated
     beneficiary healthcare benefits on the same basis as an active employee for
     180 days; to pay the management incentive compensation to which the
     Employee would otherwise have been entitled for the fiscal year in which
     death occurs; and to pay to his designated beneficiary or estate the life
     insurance, retirement and supplementary retirement benefits to which they
     are entitled within 180 days.  Upon the termination of this Agreement by
     Employer without cause, other than in connection with a "change in
     control," as such term is defined in Paragraph 1 of this Agreement, and as
     the sole and exclusive remedy against Employer for the exercise of its
     right under this Agreement to terminate this Agreement without cause,
     Employer's sole obligation shall be to pay Employee the salary in effect at
     the time of his termination, in semi-monthly installments, to continue his
     participation in the Management Incentive Compensation Plan, to provide
     healthcare and life insurance benefits and to continue his participation in
     the Retirement Plan, as amended, and the Supplemental Executive Retirement
     Plan, as amended, on the same basis as an active employee for the remaining
     term of this Agreement, without any further extensions of such term;
     provided, however, that the amount of salary shall be reduced by the

                                       7
<PAGE>
 
     salary Employee earns from reasonably comparable employment with another
     employer; and provided further that Employer's obligation to continue
     healthcare and life insurance benefits shall end when Employee is covered
     under reasonably comparable benefit plans provided by another employer.
     Upon the termination of this Agreement by Employer without cause in
     connection with a "change in control," as such term is defined in Paragraph
     1 of this Agreement, and as the sole and exclusive remedy against Employer
     for the exercise of its right under this Agreement to terminate this
     Agreement without cause, Employer's sole obligation shall be to pay
     Employee a lump sum, undiscounted cash payment equal to the compensation
     payable through the remaining term of this Agreement, as such term was
     reinstated under Paragraph 1,  to continue his participation in the
     Management Incentive Compensation Plan, to provide healthcare and life
     insurance benefits and to continue his participation in the Retirement
     Plan, as amended, and the Supplemental Executive Retirement Plan, as
     amended, on the same basis as an active employee for the remaining term of
     this Agreement, as such term was reinstated under Paragraph 1, without any
     further extensions of such term; provided, however, that Employer's
     obligation to continue healthcare and life insurance benefits shall end
     when Employee is covered under reasonably comparable benefit plans provided
     by another employer.  The resignation of Employee in response to a demand
     by Employer for the relocation of Employee outside of the United States
     shall be deemed a termination by Employer without cause for purposes of
     this Agreement.

               (d)  The respective rights and obligations of Employer and
     Employee pursuant to Paragraphs 6, 7, 8 and 9 hereof, shall survive the
     expiration or earlier termination of this Agreement.

          11.  Bonding.  Employer may apply for and maintain fidelity bonds or
similar insurance with respect to the acts and omissions of Employee.  Employee
agrees to take such steps and perform such acts as shall be necessary to assist
Employer in obtaining or maintaining in effect such bonds or insurance,
including the completion of the required applications and questionnaires, the
furnishing of any required references, and consenting, upon request, to any
required background, financial or other investigations.  Any such required
information will be treated as confidential and will be returned promptly after
the completion of such investigations.

          12.  Persons Bound.  This Agreement shall inure to the benefit of and
be binding upon Employee, his legal representatives and testate or intestate
distributees, and Employer, its successors and assigns.  This Agreement may not
be assigned by Employee.

          13.  Notices.  Any notice or request required or permitted under this
Agreement shall be in writing and given or

                                       8
<PAGE>
 
made by hand delivery or registered or certified mail, return receipt requested,
addressed to Employer or to Employee at Employer's then principal place of
business, with a copy to Employee at his home address, as set forth on the
records of Employer, or to either party hereto at such other address or
addresses as such party may from time to time specify for the purpose in a
notice similarly given to the other party.

          14.  No Waiver or Modification.  The waiver of the breach of any term
or condition of this Agreement shall not be deemed to constitute the waiver of
any other or subsequent breach of the same of any other term or condition.  No
amendment or modification of this Agreement shall be valid or binding unless
made in writing and signed by the other party against whom such waiver or

                             EMPLOYMENT AGREEMENT


          THIS EMPLOYMENT AGREEMENT (this "Agreement") dated as of APRIL 1,
1995, is between MDT TECHNIONIC COMPANY, a Delaware corporation ("Employer") and
RICHARD G. KINSEY ("Employee").

          WHEREAS, Employer and Employee desire to enter into an agreement
setting forth the terms and conditions upon which Employee shall be employed by
Employer;


                                  WITNESSETH:

     That in consideration of the mutual covenants and obligations hereinafter
set forth, the parties hereto agree as follows:

          1.   Employment and Term.

               (a)  Employer hereby employs Employee and Employee hereby accepts
     employment with and agrees to serve Employer, in the capacities and subject
     to and upon the terms and conditions hereinafter set forth.

               (b)  The term of Employee's employment hereunder shall be the
     three-year period commencing on APRIL 1, 1995 and ending on MARCH 31, 1998,
     subject to termination as provided in Paragraph 10 hereof.  Notwithstanding
     the foregoing, (i) on the second anniversary of this Agreement, the term
     hereof shall automatically be extended for an additional two years, and
     (ii) thereafter, when only two years of the term, as extended pursuant to
     clause (i) or (ii) hereof, shall remain, the term hereof shall again be
     extended for an additional year, such extensions continuing from year to
     year in the same manner; provided, however, in each case that the term
     shall not be extended, if prior to the date of such extension, Employer's
     Board of Directors gives notice to Employee or Employee gives notice to
     Employer's Board of Directors that the term shall not be so extended.

          (c)  Upon the occurrence of a change in control, as hereinafter
     defined, notwithstanding the portion of the term hereof otherwise remaining
     outstanding, the term hereof shall automatically be reinstated as a period
     of four years, commencing upon the date of such change in control.  A
     "change in control" for purposes of the preceding sentence shall mean (i)
     without prior approval of the Board of Directors of Employer, a single
     entity or group of affiliated entities acquires more than 50% of the voting
     stock of Employer issued and outstanding immediately prior to such
     acquisition; (ii) the Board of Directors of Employer approves an
     unsolicited bid by a single entity or group of affiliated entities to
     acquire more than 50% of the voting stock of Employer issued and
<PAGE>
 
     outstanding immediately prior to the approval of such acquisition, and such
     acquisition is consummated; (iii) the stockholders of Employer approve the
     consummation of any merger of Employer or any sale or other disposition of
     all or substantially all of its assets, if the stockholders of Employer
     immediately before such transaction own, immediately after consummation of
     such transaction, equity securities (other than options and other rights to
     acquire equity securities) possessing less than 50% of the voting power of
     the surviving or acquiring corporation; or (iv) a change in the majority of
     the Board of Directors of Employer during any 24-month period without the
     approval of a majority of directors in office at the beginning of such
     period.

               (d)  Upon the sale or divestiture of MDT Technionic Company,
     notwithstanding the portion of the term hereof otherwise remaining
     outstanding, the term hereof shall automatically be reinstated as a period
     of four years, commencing upon the date of such sale or divestiture.

          2.   Duties.

               (a)  Employer agrees to employ Employee as PRESIDENT with
     responsibility for the duties normally associated with such executive
     position, and for such other executive duties as the Employer's Board of
     Directors shall assign to him from time to time, subject at all times to
     the direction of Employer's Board of Directors.

               (b)  Employee agrees that so long as this Agreement continues in
     effect, he shall devote his full business time and energies to the business
     and affairs of Employer; use his best efforts, skills and abilities to
     promote the interests of Employer; and faithfully perform the duties
     described herein and such other executive duties as the Employer's Board of
     Directors shall assign to him from time to time.

          3.   Covenant.  Employee covenants and agrees that during the term of
this Agreement, he will not, directly or indirectly, either as owner, partner,
stockholder, broker, dealer, agent, employee or otherwise, engage in any other
business activity for gain or profit or other pecuniary advantage; provided,
however, that this paragraph shall not limit or restrict Employee's rights to
serve on the boards of directors of noncompeting companies or to make and have
personal investments in such form or manner as will not require his active
services in the daily operations of the businesses in which such investments are
made.

          4.   Compensation.

               (a)  Employer shall pay Employee, and Employee hereby agrees to
     accept, as partial compensation for all services rendered hereunder, an
     annual salary of not less than

                                       2
<PAGE>
 
     $132,500, payable in semi-monthly installments and subject to such
     deductions and withholdings as are required to be made pursuant to
     applicable governmental laws, rules and regulations.

               (b)  Employee shall be entitled to management incentive
     compensation in an amount equivalent to THIRTY-FIVE PERCENT (35%) of his
     annual salary, subject to the criteria detailed in the provisions of
     Employer's Management Incentive Compensation Plan.

               (c)  Employer shall also provide Employee with such health care
     benefits, disability insurance and term life insurance as Employer provides
     for its executive employees generally in amounts determined by and
     appropriately adjusted for his compensation, length of service and other
     such relevant criteria, subject to Employee's satisfaction of any
     eligibility criteria for such insurance.

               (d)  Employee shall be entitled to annual vacation time of four
     (4) weeks duration (unless under Employer's vacation policy, he is entitled
     to additional vacation time because of his length of service with the
     Company), during which time his compensation shall be paid in full.

               (e)  Employee shall be entitled to benefits under Employer's
     Retirement Plan, as amended, Supplemental Executive Retirement Plan, as
     amended, and the Post-Retirement Medical Insurance Plan in amounts
     determined by and appropriately adjusted for compensation, length of
     service and other such relevant criteria.

          5.   Expenses.  Employer agrees to pay or reimburse Employee for all
reasonable travel and other expenses incurred by Employee in connection with the
performance of his services under this Agreement, upon presentation of such
reasonably detailed expense statements, vouchers or other supporting
information, as it may from time to time request.

          6.   Confidentiality.  Employee recognizes and acknowledges that
during his employment by Employer pursuant to this Agreement he may have access
to or may obtain information of a secret, special and unique value to Employer
concerning customers, customer lists, processes, technologies, products,
formulas, devices, designs, inventions, discoveries, plans, strategies and
methods of operation (collectively and individually "Confidential Information").
Employee further recognizes and acknowledges that all Confidential Information
which is now or may hereafter be in his possession is the property of Employer
and that protection of this Confidential Information against unauthorized
disclosure or use is of critical importance to Employer in order to protect
Employer from unfair competition.  Employee therefore agrees that he will not at
any time, either while employed by

                                       3
<PAGE>
 
Employer or afterwards, without the prior written consent of the Board of
Directors of Employer, make any independent use of such Confidential
Information, or knowingly disclose the same, directly or indirectly, to any
other person, firm, corporation or other entity, for any reason or purpose
whatsoever, except to professional advisors of Employer or others who have a
business relationship with Employer and who, in Employee's judgment, have a
business need to know (e.g. advisory board members), and except on advice of
counsel during testimony under subpoena in any court or before any
administrative agency having jurisdiction or during any authorized governmental
inquiry or investigation, provided that Employee shall cooperate with Employer
in taking all reasonable and appropriate steps to assure the protection of such
Confidential Information from unauthorized use or disclosure outside of such
action, proceeding, inquiry or investigation, or except to the extent that any
such Confidential Information shall be in the public domain other than by reason
of Employee's breach of this Paragraph 6.


          7.   Ideas and Inventions.  Employee shall disclose promptly and
thereafter turn over to Employer any and all concepts and ideas for inventions,
improvements, programs, systems, novel techniques, copyrightable materials and
other valuable discoveries, whether patentable or not, which are conceived or
made by Employee solely or jointly with another during the period of employment,
on the time or property of Employer or otherwise, and which are related to the
business or activities of Employer or which Employee conceives as a result of
his employment by Employer.  Employee hereby assigns and agrees to assign to
Employer or its nominee all his interests in any of the foregoing.  Whenever
requested to do so by Employer, Employee shall execute any and all patent
applications, assignments or other transfer instruments which Employer shall
deem necessary to apply for and obtain Letters of Patent of the United States or
any foreign country or other applicable trade secret protection or to otherwise
confirm and protect Employer's interest in and ownership of all such inventions,
improvements, programs, systems, novel techniques, copyrightable materials and
other discoveries.

          8.   Restrictive Covenant.  Employee acknowledges that he is a key
executive and that the services to be rendered hereunder are of a critical
nature to the continued success of Employer.  In view of the value to Employer
of the services of Employee for which Employer has contracted hereunder, and in
recognition of Employer's obligations hereunder, Employee covenants and agrees
as follows:

               (a)  During Employee's employment hereunder, and for a period of
     two (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, solicit business for any person, firm or entity

                                       4
<PAGE>
 
     engaged primarily in developing, manufacturing and marketing medical or
     dental sterility assurance systems and examining and operatory equipment,
     or in any other business in which Employer, from time to time, shall be
     engaged in those cities or counties of the United States in which Employer
     shall then be transacting business, from any client, customer or account of
     Employer, or attempt to convert said persons or entities to other methods
     of using the same or similar products or services as provided by Employer.
     Notwithstanding the fore-going, in the event of a "change in control", as
     defined in Paragraph 1 hereof, the foregoing restriction shall apply only
     with respect to the business in which MDT Corporation is engaged, the
     cities or counties of the United States in which MDT Corporation transacted
     business and the products or services provided by MDT Corporation
     immediately prior to such change in control.

               (b)  During Employee's employment hereunder, and for a period of
     two (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, engage in developing, manufacturing and marketing
     medical or dental sterility assurance systems and examining and operatory
     equipment or in any other business in which Employer, from time to time,
     shall be engaged, in those cities or counties of the United States in which
     Employer shall then be transacting business.  Notwithstanding the foregoing
     in the event of a "change in control", as defined in Paragraph 1 hereof,
     the foregoing restriction shall apply only with respect to the business in
     which MDT Corporation is engaged and the cities or counties of the United
     States in which MDT Corporation transacted business and the products or
     services provided by MDT Corporation immediately prior to such change in
     control.

               (c)  During Employee's employment hereunder, and for a period of
     two (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, solicit for employment or employ any employee of
     Employer.

               (d)  Subparagraphs (a), (b) and (c) shall not apply in the event
     the Employee resigns within one year following a "change in control", as
     defined in Paragraph 1 hereof, that was not previously approved by the
     Board of Directors of Employer.

          As used herein, the term transacting business within "those cities and
counties" includes the carrying on of a business which may be located elsewhere
but which involves sales or any activity within the stipulated city or county.
The covenants contained in this paragraph shall be deemed to be a series of

                                       5
<PAGE>
 
separate covenants, for each city and county of each state where Employer is
carrying on such business.  If in any judicial proceeding a court shall refuse
to enforce all of the separate covenants deemed included in such action, then
such unenforceable covenants shall be deemed eliminated from the provisions
hereof for the purposes of such proceedings to the extent necessary to permit
the remaining separate covenants to be enforced in such proceed ings.

          9.   Relief.  It is recognized that in the event of Employee's breach
of Paragraphs 6, 7, or 8, the damages resulting from such breach would be
difficult, if not impossible to ascer-tain, and that Employer would be subject
to irreparable injury therefrom.  It is, therefore, agreed that Employer, in
addition to and without limiting any other remedy or right it may have, shall be
entitled to such equitable and injunctive relief as may be available to restrain
Employee from violation of any of said covenants, such right to injunctive and
equitable relief, however, to be cumulative and in addition to whatever other
remedies Employer may have in the premises, including the recovery of
consequential but not punitive damages from Employee.

          10.  Termination.

               (a)  This Agreement and the employment of Employee hereunder
     shall terminate upon the occurrence of the first to occur of the following
     events or conditions:

                    (i)  the expiration of the term specified in Paragraph 1
          hereof.

                   (ii)  the death of Employee.

                  (iii)  the incapacity of Employee for a period of six
          consecutive months to perform his duties hereunder.

                   (iv)  the election of the Board of Directors of Employer to
          terminate Employee's employment for "cause", which shall mean a
          determination by the Board of Directors of Employer in the exercise of
          its sole discretion, that there has been fraud, misappropriation,
          embezzlement, gross and continuing inattention to duty, or a
          substantial breach of this Agreement by Employee.

                    (v)  the election of the Board of Directors of Employer to
          terminate Employee's employment upon the entry of any final non
          appealable order for relief in respect of Employee under any
          bankruptcy, reorganization, arrangement, insolvency, readjustment of
          debt or similar law of any jurisdiction now or hereafter in effect if,
          in the good faith determination of the Board of Directors, such entry
          of a final, non appealable order for relief

                                       6
<PAGE>
 
          resulted from the willful neglect, financial irresponsibility or moral
          turpitude of Employee.

                   (vi)  Employee's conviction of a crime involving moral
          turpitude.

               (b)  Any termination of this Agreement pursuant to clauses (i) or
     (ii) of Subparagraph (a) of this Paragraph 10 shall be effective on the
     expiration date of this Agreement or the date of death, as the case may be.
     Any termination pursuant to clauses (iii), (iv), (v) or (vi) of
     Subparagraph (a) of this Paragraph 10 shall be effective immediately upon
     delivery of notice of termination to Employee.

               (c)  Upon the expiration or earlier termination of this Agreement
     by Employee or by Employer pursuant to Subparagraph (a) of this Paragraph
     10,  other than in connection with a "change in control", as such term is
     defined in Paragraph 1 of this Agreement, Employer's sole obligation shall
     be to pay Employee or his estate any compensation remaining unpaid through
     the effective date of termination.  In the case of the death of Employee,
     however, Employer's obligation shall be to pay Employee's designated
     beneficiary or estate the Employee's salary in effect at the time of his
     death, in semi-monthly installments, and to provide Employee's designated
     beneficiary healthcare benefits on the same basis as an active employee for
     180 days; to pay the management incentive compensation to which the
     Employee would otherwise have been entitled for the fiscal year in which
     death occurs; and to pay to his designated beneficiary or estate the life
     insurance, retirement and supplementary retirement benefits to which they
     are entitled within 180 days.  Upon the termination of this Agreement by
     Employer without cause, other than in connection with a "change in
     control," as such term is defined in Paragraph 1 of this Agreement, and as
     the sole and exclusive remedy against Employer for the exercise of its
     right under this Agreement to terminate this Agreement without cause,
     Employer's sole obligation shall be to pay Employee the salary in effect at
     the time of his termination, in semi-monthly installments, to continue his
     participation in the Management Incentive Compensation Plan, to provide
     healthcare and life insurance benefits and to continue his participation in
     the Retirement Plan, as amended, and the Supplemental Executive Retirement
     Plan, as amended, on the same basis as an active employee for the remaining
     term of this Agreement, without any further extensions of such term;
     provided, however, that the amount of salary shall be reduced by the salary
     Employee  earns from reasonably comparable employment with another
     employer; and provided further that Employer's obligation to continue
     healthcare and life insurance benefits shall end when Employee is covered
     under reasonably comparable benefit plans provided by another employer.
     Upon the termination of this Agreement by Employer without cause in

                                       7
<PAGE>
 
     connection with a "change in control," as such term is defined in Paragraph
     1 of this Agreement, and as the sole and exclusive remedy against Employer
     for the exercise of its right under this Agreement to terminate this
     Agreement without cause, Employer's sole obligation shall be to pay
     Employee a lump sum, undiscounted cash payment equal to the compensation
     payable through the remaining term of this Agreement, as such term was
     reinstated under Paragraph 1,  to continue his participation in the
     Management Incentive Compensation Plan, to provide healthcare and life
     insurance benefits and to continue his participation in the Retirement
     Plan, as amended, and the Supplemental Executive Retirement Plan, as
     amended, on the same basis as an active employee for the remaining term of
     this Agreement, as such term was reinstated under Paragraph 1, without any
     further extensions of such term; provided, however, that Employer's
     obligation to continue healthcare and life insurance benefits shall end
     when Employee is covered under reasonably comparable benefit plans provided
     by another employer.  The resignation of Employee in response to a demand
     by Employer for the relocation of Employee outside of the United States
     shall be deemed a termination by Employer without cause for purposes of
     this Agreement.

               (d)  The respective rights and obligations of Employer and
     Employee pursuant to Paragraphs 6, 7, 8 and 9 hereof, shall survive the
     expiration or earlier termination of this Agreement.

          11.  Bonding.  Employer may apply for and maintain fidelity bonds or
similar insurance with respect to the acts and omissions of Employee.  Employee
agrees to take such steps and perform such acts as shall be necessary to assist
Employer in obtaining or maintaining in effect such bonds or insurance,
including the completion of the required applications and questionnaires, the
furnishing of any required references, and consenting, upon request, to any
required background, financial or other investigations.  Any such required
information will be treated as confidential and will be returned promptly after
the completion of such investigations.

          12.  Persons Bound.  This Agreement shall inure to the benefit of and
be binding upon Employee, his legal representatives and testate or intestate
distributees, and Employer, its successors and assigns.  This Agreement may not
be assigned by Employee.

          13.  Notices.  Any notice or request required or permitted under this
Agreement shall be in writing and given or made by hand delivery or registered
or certified mail, return receipt requested, addressed to Employer or to
Employee at Employer's then principal place of business, with a copy to Employee
at his home address, as set forth on the records of Employer, or to either party
hereto at such other address or

                                       8
<PAGE>
 
addresses as such party may from time to time specify for the purpose in a
notice similarly given to the other party.

          14.  No Waiver or Modification.  The waiver of the breach of any term
or condition of this Agreement shall not be deemed to constitute the waiver of
any other or subsequent breach of the same of any other term or condition.  No
amendment or modification of this Agreement shall be valid or binding unless

                              EMPLOYMENT AGREEMENT


     THIS EMPLOYMENT AGREEMENT (this "Agreement") dated as of APRIL 1, 1995, is
between MDT CORPORATION, a Delaware corporation ("Employer") and CREIGHTON A.
WHITE ("Employee").

     WHEREAS, Employer and Employee desire to enter into an agreement setting
forth the terms and conditions upon which Employee shall be employed by
Employer;


                                  WITNESSETH:


     That in consideration of the mutual covenants and obligations hereinafter
set forth, the parties hereto agree as follows:

     1.   Employment and Term.

          (a)  Employer hereby employs Employee and Employee hereby accepts
     employment with and agrees to serve Employer, in the capacities and subject
     to and upon the terms and conditions  hereinafter set forth.

          (b)  The term of Employee's employment hereunder shall be the three-
     year period commencing on APRIL 1, 1995 and ending on MARCH 31, 1998,
     subject to termination as provided in Paragraph 10 hereof.  Notwithstanding
     the foregoing, (i) on the second anniversary of this Agreement, the term
     hereof shall automatically be extended for an additional two years, and
     (ii) thereafter, when only two years of the term, as extended pursuant to
     clause (i) or (ii) hereof, shall remain, the term hereof shall again be
     extended for an additional year, such extensions continuing from year to
     year in the same manner; provided, however, in each case that the term
     shall not be extended, if prior to the date of such extension, Employer's
     Board of Directors gives notice to Employee or Employee gives notice to
     Employer's Board of Directors that the term shall not be so extended.

          (c)  Upon the occurrence of a change in control, as hereinafter
     defined, notwithstanding the portion of the term hereof otherwise remaining
     outstanding, the term hereof shall automatically be reinstated as a period
     of four years, commencing upon the date of such change in control. A
     "change in control" for purposes of the preceding sentence shall mean (i)
     without prior approval of the Board of Directors of Employer, a single
     entity or group of affiliated entities acquires more than 50% of the voting
     stock of Employer issued and outstanding immediately prior to such
     acquisition; (ii) the Board of Directors of Employer

                                       1
<PAGE>
 
     approves an unsolicited bid by a single entity or group of affiliated
     entities to acquire more than 50% of the voting stock of Employer issued
     and outstanding immediately prior to the approval of such acquisition, and
     such acquisition is consummated; (iii) the stockholders of Employer approve
     the consummation of any merger of Employer or any sale or other disposition
     of all or substantially all of its assets, if the stockholders of Employer
     immediately before such transaction own, immediately after consummation of
     such transaction, equity securities (other than options and other rights to
     acquire equity securities) possessing less than 50% of the voting power of
     the surviving or acquiring corporation; or (iv) a change in the majority of
     the Board of Directors of Employer during any 24-month period without the
     approval of a majority of directors in office at the beginning of such
     period.

     2.   Duties.

          (a)  Employer agrees to employ Employee as VICE PRESIDENT, CORPORATE,
     GOVERNMENTAL AND INTERNATIONAL GROUP with responsibility for the duties
     normally associated with such executive position, and for such other
     executive duties as the Employer's Board of Directors shall assign to him
     from time to time, subject at all times to the direction of Employer's
     Board of Directors.

          (b)  Employee agrees that so long as this Agreement continues in
     effect, he shall devote his full business time and energies to the business
     and affairs of Employer; use his best efforts, skills and abilities to
     promote the interests of Employer; and faithfully perform the duties
     described herein and such other executive duties as the Employer's Board of
     Directors shall assign to him from time to time.

     3.   Covenant.  Employee covenants and agrees that during the term of this
     Agreement, he will not, directly or indirectly, either as owner, partner,
     stockholder, broker, dealer, agent, employee or otherwise, engage in any
     other business activity for gain or profit or other pecuniary advantage;
     provided, however, that this paragraph shall not limit or restrict
     Employee's rights to serve on the boards of directors of noncompeting
     companies or to make and have personal investments in such form or manner
     as will not require his active services in the daily operations of the
     businesses in which such investments are made.

     4.   Compensation.

          (a)  Employer shall pay Employee, and Employee hereby agrees to
     accept, as partial compensation for all services rendered hereunder, an
     annual salary of not less than

                                       2
<PAGE>
 
     $132,000, payable in semi-monthly installments and subject to such
     deductions and withholdings as are required to be made pursuant to
     applicable governmental laws, rules and regulations.

          (b)  Employee shall be entitled to management incentive compensation
     in an amount equivalent to THIRTY PERCENT (30%) of his annual salary,
     subject to the criteria detailed in the provisions of Employer's Management
     Incentive Compensation Plan.

          (c)  Employer shall also provide Employee with such health care
     benefits, disability insurance and term life insurance as Employer provides
     for its executive employees generally in amounts determined by and
     appropriately adjusted for his compensation, length of service and other
     such relevant criteria, subject to Employee's satisfaction of any
     eligibility criteria for such insurance.

          (d)  Employee shall be entitled to annual vacation time of four (4)
     weeks duration (unless under Employer's vacation policy, he is entitled to
     additional vacation time because of his length of service with the
     Company), during which time his compensation shall be paid in full.

          (e)  Employee shall be entitled to benefits under Employer's
     Retirement Plan, as amended, Supplemental Executive Retirement Plan, as
     amended, and the Post-Retirement Medical Insurance Plan in amounts
     determined by and appropriately adjusted for compensation, length of
     service and other such relevant criteria.

     5.   Expenses.  Employer agrees to pay or reimburse Employee for all
     reasonable travel and other expenses incurred by Employee in connection
     with the performance of his services under this Agreement, upon
     presentation of such reasonably detailed expense statements, vouchers or
     other supporting information, as it may from time to time request.

     6.   Confidentiality.  Employee recognizes and acknowledges that during his
     employment by Employer pursuant to this Agreement he may have access to or
     may obtain information of a secret, special and unique value to Employer
     concerning customers, customer lists, processes, technologies, products,
     formulas, devices, designs, inventions, discoveries, plans, strategies and
     methods of operation (collectively and individually "Confidential
     Information").  Employee further recognizes and acknowledges that all
     Confidential Information which is now or may hereafter be in his possession
     is the property of Employer and that protection of this Confidential
     Information against unauthorized disclosure or use is of critical
     importance to Employer in order to protect Employer from unfair

                                       3
<PAGE>
 
     competition.  Employee therefore agrees that he will not at any time,
     either while employed by Employer or afterwards, without the prior written
     consent of the Board of Directors of Employer, make any independent use of
     such Confidential Information, or knowingly disclose the same, directly or
     indirectly, to any other person, firm, corporation or other entity, for any
     reason or purpose whatsoever, except to professional advisors of Employer
     or others who have a business relationship with Employer and who, in
     Employee's judgment, have a business need to know (e.g. advisory board
     members), and except on advice of counsel during testimony under subpoena
     in any court or before any administrative agency having jurisdiction or
     during any authorized governmental inquiry or investigation, provided that
     Employee shall cooperate with Employer in taking all reasonable and
     appropriate steps to assure the protection of such Confidential Information
     from unauthorized use or disclosure outside of such action, proceeding,
     inquiry or investigation, or except to the extent that any such
     Confidential Information shall be in the public domain other than by reason
     of Employee's breach of this Paragraph 6.

     7.  Ideas and Inventions.  Employee shall disclose promptly and thereafter
     turn over to Employer any and all concepts and ideas for inventions,
     improvements, programs, systems, novel techniques, copyrightable materials
     and other valuable discoveries, whether patentable or not, which are
     conceived or made by Employee solely or jointly with another during the
     period of employment, on the time or property of Employer or otherwise, and
     which are related to the business or activities of Employer or which
     Employee conceives as a result of his employment by Employer.  Employee
     hereby assigns and agrees to assign to Employer or its nominee all his
     interests in any of the foregoing.  Whenever requested to do so by
     Employer, Employee shall execute any and all patent applications,
     assignments or other transfer instruments which Employer shall deem
     necessary to apply for and obtain Letters of Patent of the United States or
     any foreign country or other applicable trade secret protection or to
     otherwise confirm and protect Employer's interest in and ownership of all
     such inventions, improvements, programs, systems, novel techniques,
     copyrightable materials and other discoveries.

     8.   Restrictive Covenant.  Employee acknowledges that he is a key
     executive and that the services to be rendered hereunder are of a critical
     nature to the continued success of Employer. In view of the value to
     Employer of the services of Employee for which Employer has contracted
     hereunder, and in recognition of Employer's obligations hereunder, Employee
     covenants and agrees as follows:

                                       4
<PAGE>
 
          (a)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, solicit business for any person, firm or entity
     engaged primarily in developing, manufacturing and marketing medical or
     dental sterility assurance systems and examining and operatory equipment,
     or in any other business in which Employer, from time to time, shall be
     engaged in those cities or counties of the United States in which Employer
     shall then be transacting business, from any client, customer or account of
     Employer, or attempt to convert said persons or entities to other methods
     of using the same or similar products or services as provided by Employer.
     Not-withstanding the foregoing, in the event of a "change in control", as
     defined in Paragraph 1 hereof, the foregoing restriction shall apply only
     with respect to the business in which MDT Corporation is engaged, the
     cities or counties of the United States in which MDT Corporation transacted
     business and the products or services provided by MDT Corporation
     immediately prior to such change in control.

          (b)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, as employee, consultant, officer, director,
     partner, or stockholder, engage in developing, manufacturing and marketing
     medical or dental sterility assurance systems and examining and operatory
     equipment or in any other business in which Employer, from time to time,
     shall be engaged, in those cities or counties of the United States in which
     Employer shall then be transacting business.   Notwithstanding the
     foregoing in the event of a "change in control", as defined in Paragraph 1
     hereof, the foregoing restriction shall apply only with respect to the
     business in which MDT Corporation is engaged and the cities or counties of
     the United States in which MDT Corporation transacted business and the
     products or services provided by MDT Corporation immediately prior to such
     change in control.

          (c)  During Employee's employment hereunder, and for a period of two
     (2) years after he ceases to be employed by Employer by reason of
     Employee's resignation or termination for cause, Employee shall not,
     directly or indirectly, solicit for employment or employ any employee of
     Employer.

          (d)  Subparagraphs (a), (b) and (c) shall not apply in the event the
     Employee resigns within one year following a "change in control", as
     defined in Paragraph 1 hereof, that was not previously approved by the
     Board of Directors of Employer.

                                       5
<PAGE>
 
     As used herein, the term transacting business within "those cities and
     counties" includes the carrying on of a business which may be located
     elsewhere but which involves sales or any activity within the stipulated
     city or county.  The covenants contained in this paragraph shall be deemed
     to be a series of separate covenants, for each city and county of each
     state where Employer is carrying on such business.  If in any judicial
     proceeding a court shall refuse to enforce all of the separate covenants
     deemed included in such action, then such unenforceable covenants shall be
     deemed eliminated from the provisions hereof for the purposes of such
     proceedings to the extent necessary to permit the remaining separate
     covenants to be enforced in such proceedings.

     9.   Relief.  It is recognized that in the event of Employee's breach of
     Paragraphs 6, 7, or 8, the damages resulting from such breach would be
     difficult, if not impossible to ascertain, and that Employer would be
     subject to irreparable injury therefrom.  It is, therefore, agreed that
     Employer, in addition to and without limiting any other remedy or right it
     may have, shall be entitled to such equitable and injunctive relief as may
     be available to restrain Employee from violation of any of said covenants,
     such right to injunctive and equitable relief, however, to be cumulative
     and in addition to whatever other remedies Employer may have in the
     premises, including the recovery of consequential but not punitive damages
     from Employee.

     10.  Termination.

          (a)  This Agreement and the employment of Employee hereunder shall
     terminate upon the occurrence of the first to occur of the following events
     or conditions:

               (i)  the expiration of the term specified in Paragraph 1 hereof.

              (ii)  the death of Employee.

             (iii)  the incapacity of Employee for a period of six consecutive
     months to perform his duties hereunder.

              (iv)  the election of the Board of Directors of Employer to
     terminate Employee's employment for "cause", which shall mean a
     determination by the Board of Directors of Employer in the exercise of its
     sole discretion, that there has been fraud, misappropriation, embezzlement,
     gross and continuing inattention to duty, or a substantial breach of this
     Agreement by Employee.

               (v)  the election of the Board of Directors of Employer to
     terminate Employee's employment upon the entry

                                       6
<PAGE>
 
     of any final non appealable order for relief in respect of Employee under
     any bankruptcy, reorganization, arrangement, insolvency, readjustment of
     debt or similar law of any jurisdiction now or hereafter in effect if, in
     the good faith determination of the Board of Directors, such entry of a
     final, non appealable order for relief resulted from the willful neglect,
     financial irresponsibility or moral turpitude of Employee.

              (vi)  Employee's conviction of a crime involving moral turpitude.

          (b)  Any termination of this Agreement pursuant to clauses (i) or (ii)
     of Subparagraph (a) of this Paragraph 10 shall be effective on the
     expiration date of this Agreement or the date of death, as the case may be.
     Any termination pursuant to clauses (iii), (iv), (v) or (vi) of
     Subparagraph (a) of this Paragraph 10 shall be effective immediately upon
     delivery of notice of termination to Employee.

          (c)  Upon the expiration or earlier termination of this Agreement by
     Employee or by Employer pursuant to Subparagraph (a) of this Paragraph 10,
     other than in connection with a "change in control", as such term is
     defined in Paragraph 1 of this Agreement, Employer's sole obligation shall
     be to pay Employee or his estate any compensation remaining unpaid through
     the effective date of termination. In the case of the death of Employee,
     however, Employer's obligation shall be to pay Employee's designated
     beneficiary or estate the Employee's salary in effect at the time of his
     death, in semi-monthly installments, and to provide Employee's designated
     beneficiary healthcare benefits on the same basis as an active employee for
     180 days; to pay the management incentive compensation to which the
     Employee would otherwise have been entitled for the fiscal year in which
     death occurs; and to pay to his designated beneficiary or estate the life
     insurance, retirement and supplementary retirement benefits to which they
     are entitled within 180 days.  Upon the termination of this Agreement by
     Employer without cause, other than in connection with a "change in
     control," as such term is defined in Paragraph 1 of this Agreement, and as
     the sole and exclusive remedy against Employer for the exercise of its
     right under this Agreement to terminate this Agreement without cause,
     Employer's sole obligation shall be to pay Employee the salary in effect at
     the time of his termination, in semi-monthly installments, to continue his
     participation in the Management Incentive Compensation Plan, to provide
     healthcare and life insurance benefits and to continue his participation in
     the Retirement Plan, as amended, and the Supplemental Executive Retirement
     Plan, as amended, on the same basis as an active employee for the remaining
     term of this Agreement, without any further

                                       7
<PAGE>
 
     extensions of such term; provided, however, that the amount  of salary
     shall be reduced by the salary Employee earns from reasonably comparable
     employment with another employer; and provided further that Employer's
     obligation to continue healthcare and life insurance benefits shall end
     when Employee is covered under reasonably comparable benefit plans provided
     by another employer.  Upon the termination of this Agreement by Employer
     without cause in connection with a "change in control," as such term is
     defined in Paragraph 1 of this Agreement, and as the sole and exclusive
     remedy against Employer for the exercise of its right under this Agreement
     to terminate this Agreement without cause, Employer's sole obligation shall
     be to pay Employee a lump sum, undiscounted cash payment equal to the
     compensation payable through the remaining term of this Agreement, as such
     term was reinstated under Paragraph 1,  to continue his participation in
     the Management Incentive Compensation Plan, to provide healthcare and life
     insurance benefits and to continue his participation in the Retirement
     Plan, as amended, and the Supplemental Executive Retirement Plan, as
     amended, on the same basis as an active employee for the remaining term of
     this Agreement, as such term was reinstated under Paragraph 1, without any
     further extensions of such term; provided, however, that Employer's
     obligation to continue healthcare and life insurance benefits shall end
     when Employee is covered under reasonably comparable benefit plans provided
     by another employer.  The resignation of Employee in response to a demand
     by Employer for the relocation of Employee outside of the United States
     shall be deemed a termination by Employer without cause for purposes of
     this Agreement.

          (d)  The respective rights and obligations of Employer and Employee
     pursuant to Paragraphs 6, 7, 8 and 9 hereof, shall survive the expiration
     or earlier termination of this Agreement.

     11.  Bonding.  Employer may apply for and maintain fidelity bonds or
     similar insurance with respect to the acts and omissions of Employee.
     Employee agrees to take such steps and perform such acts as shall be
     necessary to assist Employer in obtaining or maintaining in effect such
     bonds or insurance, including the completion of the required applications
     and questionnaires, the furnishing of  any  required references, and
     consenting, upon request, to any required background, financial or other
     investigations.  Any such required information will be treated as
     confidential and will be returned promptly after the completion of such
     investigations.

     12.  Persons Bound.  This Agreement shall inure to the benefit of and be
     binding upon Employee, his legal representatives and testate or intestate
     distributees, and

                                       8
<PAGE>
 
     Employer, its successors and assigns.  This Agreement may not be assigned
     by Employee.

     13.  Notices.  Any notice or request required or permitted under this
     Agreement shall be in writing and given or made by hand delivery or
     registered or certified mail, return receipt requested, addressed to
     Employer or to Employee at Employer's then principal place of business,
     with a copy to Employee at his home address, as set forth on the records of
     Employer, or to either party hereto at such other address or addresses as
     such party may from time to time specify for the purpose in a notice
     similarly given to the other party.

     14.  No Waiver or Modification.  The waiver of the breach of any term or
     condition of this Agreement shall not be deemed to constitute the waiver of

                                                                        -----

COUNTY OF DURHAM:


     THIS LEASE, made as of this   [17th]   day of February, 1995, by and
                                 ----------                              
between PETULA ASSOCIATES, LTD., an Iowa corporation, hereinafter "Landlord",
and  MDT CORPORATION, a Delaware corporation hereinafter "Tenant".

                                  WITNESSETH:

     Upon the terms and conditions hereinafter set forth, the Landlord leases to
Tenant and Tenant leases from Landlord property hereinafter defined and referred
to as the Premises, all as follows;

    1.    PREMISES.  The property hereby leased to Tenant is:

          That area shown on Exhibit A-1 (Space Plan) which is known as Suite
          200, consisting of approximately 6,006 rentable square feet currently
          estimated and shall be located in the Stratford Hall Building (the
          "Building") to be constructed, the above-described leased property
          being herein referred to as the Premises, which is also indicated on
          Exhibits A-2 (Floor Plan) and A-3 (Site Plan).  The Building, to be
          located at the Imperial Center, Research Triangle Park, Durham County,
          North Carolina, shall be constructed on real property more
          particularly described in that legal description attached as Exhibit
          A-4.  The rentable square feet area of the space occupied by Tenant
          under this Lease shall be computed by multiplying the result of the
          Building Owners and Managers Association (BOMA) method of measuring
          space on a multi-tenant floor basis by 1.1416, the applicable core
          area factor.  Using this formula for calculating rentable square feet
          for the Premises, a result of 6,006 rentable square feet is initially
          estimated.

    2.    TERM; MEASUREMENT OF SPACE; FAILURE TO DELIVER PREMISES  The term of
this Lease shall be for a period of seventy four (74) months and shall commence
on that date Landlord delivers to Tenant possession of the Premises in a
condition "suitable for occupancy" (as defined below), which date is projected
as June 1, 1995, (the "projected commencement date"). Accordingly, assuming

                                       1
<PAGE>
 
a June 1, 1995 commencement date, this Lease shall expire and terminate (unless
extended as herein provided) at midnight on July 31, 2001.  If for any reason
whatsoever, Landlord cannot deliver possession of the Premises to Tenant in a
condition "suitable for occupancy" as of the foregoing projected commencement
date, this Lease shall not be void or voidable (except as provided below); no
obligation of Tenant shall be affected thereby (unless Tenant duly exercises its
right of cancellation as provided below); and neither Landlord nor Landlord's
agents shall be liable to Tenant for any loss or damages resulting therefrom;
provided, however, that if possession of the Premises is not then delivered as
of August 1, 1995 to Tenant in a condition "suitable for occupancy" (except if
such late delivery is the result of "Tenant delay", as defined below) Landlord
shall pay to Tenant the sum of Seven Thousand Five Hundred Dollars ($7,500.00)
per month for a term not to exceed six (6) months (such amount to be pro-rated
in the event Landlord delivers possession after August 1, 1995 but on a day
which is not the first day of a month) until possession is delivered, or,
alternately, Tenant may, at its option, accept similar space in another building
of which this Landlord is landlord (or has a controlling interest in landlord)
under and pursuant to the same terms and conditions of this Lease, unless
otherwise modified by the mutual written agreement of Landlord and Tenant.  In
the event that Landlord delivers possession of the Premises in a condition
"suitable for occupancy" after the projected commencement date, then the actual
commencement and expiration dates of this Lease and all other dates affected
thereby shall be revised to conform all affected dates under this Lease to the
date Landlord actually delivers possession of the Premises to Tenant.  If with
Landlord's prior written approval, Tenant occupies the Premises prior to the
projected commencement date specified above, such occupancy by Tenant shall be
subject to all terms and conditions of this Lease, shall not advance the
expiration date, and Tenant shall pay prorated rent for such period of occupancy
at the initial monthly rates set forth below.  Sums due Tenant pursuant to this
paragraph one of this Section 2 for late delivery shall, at Tenant's option, be
paid in cash when accrued or applied to rent next due under this Lease.

     If upon Tenant's occupancy of the Premises, the actual amount of rentable
square feet for the Premises is determined to be greater or less than the amount
of currently estimated rentable square feet for the Premises (as stated above)
for whatever reason, including, without limitation, modifications in the
construction of the Building, then and in that event, the amount of rentable
square feet, as adjusted, together with resulting modifications of rent to be
paid hereunder, shall be set forth in an Acceptance of Premises Memorandum, the
form of which is attached as Exhibit B hereto, and which will be promptly

                                       2
<PAGE>
 
(i.e., within ten business (10) days of Tenant's occupancy) executed by the
Landlord and Tenant, and upon such execution and delivery by the parties hereto,
made a part hereof.

     If Landlord cannot deliver possession of the Premises to Tenant in a
condition "suitable for occupancy" as of the projected commencement date
referenced above, then subject to a grace provision period not to exceed ninety
(90) days from the projected commencement date (except that an event of force
majeure [not exceeding ninety (90) consecutive days in length] or a delay caused
by a Tenant delay either before or after the projected commencement date shall
be excluded in calculating such period on a per diem basis), and provided Tenant
is not then in default thereunder, Tenant may then, and in such an event only,
terminate this Lease by written notice to Landlord, whereupon neither party
shall have any further obligation or liability to the other, and further
provided that such written notice shall have no effect if given after Tenant
takes possession of the Premises, or any part thereof.

     As used herein, the term "Landlord delivered to Tenant possession of the
Premises" and such similarly stated terms set forth above shall mean that the
Premises are "suitable for occupancy", but shall not include Tenant's entering
the Premises on a temporary basis for the purpose of measuring or inspecting the
Premises, or otherwise engaging in limited activity which does not constitute
occupancy (including, without limitation, the moving in of certain furnishings
or limited Tenant upfit subject to Landlord's consent which shall not be
unreasonably withheld or delayed, prior to the completion of Tenant
Improvements).

     As used herein, the term "suitable for occupancy" shall mean that the
following conditions have been met:  (a) a "Certificate of Occupancy," temporary
or final, has been issued by the appropriate governmental entity permitting
Tenant's use and occupancy of the Premises; (b) the Tenant Improvements have
been constructed and completed in all material respects for the Premises in
accordance with approved plans and specifications as certified by the architect
(subject only to an agreed to punch list); and (c) all means of access
(including, without limitation, corridors, elevators and stairways, heating and
ventilating, air-conditioning, sanitary sewer, water, parking, telephone access,
and electrical lighting and power facilities) have been installed, are in good
operating order, and are available to Tenant.

     As used herein, the term "Tenant delay" shall mean an event of delay due
directly as the result of the conduct or fault of the Tenant, including Tenant's
failure to deliver Final Tenant

                                       3
<PAGE>
 
Improvement Plans and Specifications on or before February 24, 1995, as required
pursuant to Section 9 hereof.

     3.   RENT.  All rent payable by Tenant shall be without previous demand
therefor by Landlord, and without setoff or deduction (except as provided in
Section 16 below).  Provided that Tenant is then not in default hereunder after
notice and the applicable cure period, if any, no rent shall be due from Tenant
for the first two (2) months.  Thereafter, commencing as of the third month of
the term of this Lease, i.e. projected as August, 1995, the Minimum Rent for the
initial term shall be the sum of  Six Hundred Three Thousand Six Hundred Three
and 00/100 ($603,603.00) Dollars, which rent shall be payable in advance in
equal monthly installments as follows:

</TABLE> 

Each monthly installment of rent shall be payable on or before the first day of
each calendar month during the term of this Lease, unless the term commences
other than on the first day of the month, in which event rent at the above rate
pro-rated until the end of that month shall be due and payable on the
commencement date.  In addition to such remedies as may be provided under the
default provisions of this Lease, Landlord shall be entitled to a late charge of
four percent (4%) of the amount of the monthly rent if not received within five
(5) business days after the date due, and a charge of Twenty Dollars ($20.00) or
the maximum amount allowed by law, whichever is less, for any check given by
Tenant not paid when first presented by Landlord.

     In the event of a default under the terms of this Lease after notice and
applicable cure period, if any, Landlord, in addition to any other right and
remedy available to Landlord, shall be entitled to recover from Tenant, and
Tenant shall immediately pay to Landlord upon Landlord's demand therefor, the
full amount of rent forgiven with respect to the first two (2) months of the
term of this Lease.

                                       4

     4.  INCREASES IN OPERATING EXPENSES.  The Tenant agrees to pay to Landlord
as additional rent for each year (or portion hereof) during the term of this
Lease Tenant's Proportionate Share (as defined below) of the total of any
increases (the "Operating Expense Differential") in operating expenses incurred
on account of the operation or maintenance of the Building and adjoining common
areas (being shown in yellow on Exhibit A-3) above $4.80 ("Base Operating
Expense") per rentable square foot.

     As used herein, the term "operating expense" shall include all direct costs
of operation and maintenance as determined by standard accounting practices and
shall include, by way of illustration, but is not limited to:  costs of property
management services, ad valorem real and personal property taxes (but exclusive
of personal property taxes of a tenant), reasonable legal fees and other costs
incurred in connection with protesting any tax assessment, hazard and liability
insurance premiums, utilities, heat, air conditioning, janitorial and
maintenance services, landscaping, snow removal, common area asphalt and
pavement repair, labor, materials, supplies, equipment and tools (used in
connection with the Building or the common area), permits, licenses and
inspection fees.  The term "operating expense" shall not include depreciation on
the Building in which the Premises is located or equipment therein (except for
the reasonable amortization of the costs for capital improvements or investment
items which are purchased or installed after the commencement date of the Lease
for the purpose of reducing "operating expenses"), interest, executive salaries,
real estate brokers commissions and other costs incurred to lease space in the
Building, costs to correct a Building defect, a violation of law or an
environmental condition relating to the Building not caused by the Tenant, costs
reimbursable to Landlord by third parties (including insurance proceeds), costs
(including utility costs) attributable to particular tenant(s) but not tenants
in general, costs to repair or reconstruct casualty damage or to restore the
Building in the event of condemnation, costs of defending litigation relating to
Landlord's ownership of the Building, and income taxes of Landlord.

     If in the twelve (12) month period preceding the computation of each
Operating Expense Differential, the occupancy of the net rentable area of the
Building averages less than ninety-five percent (95%), then it is agreed that
the Operating Expense Differential will be adjusted for such year so that all
such operating expenses shall be computed as though the rentable area of the
Building had been ninety-five percent (95%) occupied for such lease year.  All
such expense categories will be equitably accounted for, and reported for, and
in accordance with generally accepted accounting procedures.

                                       5
<PAGE>
 
     As used herein, the term "Tenant's Proportionate Share" of the Operating
Expense Differential shall mean that percentage found by dividing the rentable
square footage area of the Premises (i.e., approximately 6,006 rentable square
feet, subject to measurement pursuant to Section 2 above) by the rentable square
footage of the Building (i.e., approximately 75,983 rentable square feet,
subject to measurement).  (For example, assuming currently estimated footages,
the "Tenant's Proportionate Share" computation is as follows:  6,006 rentable
square divided by 75,983 rentable square feet equals 7.904%).  If at any time
during the term of this lease, the square footage of either the Premises or the
Building is materially adjusted, then and in that event, this definition of
"Tenant's Proportionate Share" shall be modified in accordance with its terms.

     Statements showing the actual operating expenses of the Building and common
areas and Tenant's Proportionate Share thereof (hereinafter referred to as the
"Statement of Actual Operating Expense Adjustments") shall be delivered by
Landlord to Tenant within ninety (90) days after the end of each lease year in
which such sums as additional rent were paid by, or due from, Tenant under the
terms hereof.  Within fifteen (15) days after Tenant's receipt of the Statement
of Actual Operating Expense Adjustments, Tenant shall pay to Landlord the amount
of any sums shown as being due and unpaid thereon, or alternately, Landlord
shall credit to Tenant the amount of any sums showed as overpaid by Tenant (or,
with respect to overpayments made by Tenant during the last year of the Lease
term, Landlord shall pay to Tenant in cash the amount of such overpayment,
provided that Tenant is not then in default hereunder after notice and the
applicable cure period, if any).  The Statement of Annual Operating Expense
Adjustment (the "Statement") shall be available for audit by Tenant who at its
own expense may request and cause an audit to be performed of the Statement by a
qualified accountant.  In the event that with respect to the Statement, Tenant's
audit establishes an error in excess of five percent (5%), then and in that
event, Landlord shall pay the reasonable costs of such audit upon Tenant's
request therefor.

     Commencing with the first month of the second lease year, and each lease
year thereafter, there shall be added to Tenant's monthly payments an amount
equal to 1/12 of Tenant's Proportionate Share of the Operating Expense
Differential for the year in progress as estimated by Landlord.  These monthly
payments (as estimated by Landlord) shall be paid as additional rent by Tenant
until such time as actual figures are available (after the end of the second and
successive lease years), when the monthly payments and future estimated monthly
payments shall be adjusted to reflect the prior year's experience.

                                       6
<PAGE>
 
     If the last year of this Lease should be less than a full twelve (12) month
period, the amount shown as due by Tenant on the Statement of Actual Operating
Expense Adjustments shall reflect a proration based on the proportion that the
number of days this Lease was in effect during such last year bears to the
number 360.  Landlord's right to recover Tenant's Proportionate Share of the
Operating Expense Differential due, or Tenant's right to recover any
overpayment, shall survive the termination or expiration of this Lease.

     Tenant also agrees to pay to Landlord as additional rent for each year
during the term of this Lease, Tenant's proportionate share of business park
(known as the "Imperial Center" as shown generally on Exhibit A-3) pass-through
costs, which means and includes the costs to Landlord arising from the operation
of business park amenities and common areas (for the nonexclusive benefit of
tenants at the business park) including, without limitation, property management
fees and other direct expense items as listed in the second full paragraph of
this Section 4, costs of maintenance for common area facilities (serving the
business park) and other business park amenities.  Tenant's proportionate share
of business park pass-through costs shall be determined from a percentage found
by dividing the agreed to rentable square footage of the Premises by the
rentable square footage of all benefiting buildings within the business park
(which includes buildings owned by third parties).  All provisions contained in
this Section 4, above, relating to the issuance of statements, reportings,
yearly reconciliations and the like, shall also apply to this obligation of
Tenant to business park pass-through costs.


     5.  OPTION TO EXTEND.  Provided that Tenant is not then in default
hereunder (i.e., after Landlord's notice and Tenant's failure to cure within the
applicable cure period, if any), and provided further that Tenant gives Landlord
at least one hundred eighty (180) days prior written notice of Tenant's exercise
of this option to extend (failure to give such notice being an absolute bar to
any right on the part of Tenant to so extend), Landlord hereby gives to Tenant
the right to extend this Lease for a term of three (3) years, this extension
term to expire (unless sooner terminated pursuant to this Lease) with the
expiration date of such extended term (if exercised) to be set forth by
endorsement to the Acceptance of Premises Memorandum.  All the terms and
conditions of this Lease shall remain and be in effect during the extension term
save and except that the rent to be paid by the Tenant during such extension
term shall be an amount equal to the then market rate equivalent for comparable
space in the Research Triangle Park, North Carolina area as calculated by
appraisal set forth below, or such other rate as

                                       7
<PAGE>
 
may be mutually agreed upon by Landlord and Tenant. Landlord and Tenant agree to
establish the rent due for the extension term within thirty (30) days of
Tenant's exercise of the option herein granted.  If the parties are unable to
agree as to rent to be paid for the extension term within the aforesaid thirty
(30) day period, then such rent shall be determined by process of directed
appraisal (as set forth below), provided nevertheless that in no event shall the
rent due for the extension term be less than the previously existing rate of
rent under this Lease. Subject to the aforesaid qualification and further
provided that upon appointment of the appraisers (as provided below) each of
Landlord and Tenant shall submit to the appraisers by sealed envelope their
numerical determination of the rent (i.e., term, annually and monthly) which in
the respective opinion of each party should be in effect for the extension term,
which numerical determinations by each of the parties shall set the absolute
range for rent during the extension term, otherwise the rent due for the
extension term shall be that amount which an unrelated party would be willing to
pay the Landlord for the Demised Premises pursuant to an arms-length
negotiation. In the event that rent for the extension term is not mutually
agreed upon within the aforesaid thirty (30) day period, then subject to the
aforesaid qualifications, each of Landlord and Tenant shall specify within five
(5) days after the expiration of such aforesaid thirty (30) day period, a
selection of a qualified appraiser by written notice to the other.  Within
twenty (20) days after the selection of the last appraiser, the two (2)
appraisers (one selected by Landlord and the other selected by Tenant) shall
render a joint written determination of the rent payable for the extension term
(stated for each of the term, annually and monthly, and subject nevertheless to
the numerical range established by the parties).  If the two (2) appraisers are
unable to agree upon a joint written determination within the aforesaid twenty
(20) day period and subject to the numerical range, each appraiser shall then
render his or her own determination and provided that each appraisal is within
twenty percent (20%) of the other, the two (2) appraisers shall select a third
appraiser within such twenty (20) day period.  (If the two (2) appraisals as
aforesaid are not within twenty percent (20%) of each other, then and in that
event, the appraisal process shall be re-initiated by the parties choosing
different appraisers).  Within ten (10) days after the appointment of a third
appraiser, the third appraiser shall select one of the determinations of the two
(2) appraisers originally selected, or if neither such appraisal represents that
value which a third party would be willing to pay the Landlord in a arms-length
negotiation, select a value which represents a number between the two (2)
appraisal values originally determined by the two (2) original appraisers but
still nevertheless subject to the numerical range initially established by the
parties.  All

                                       8
<PAGE>
 
appraisers selected pursuant to this Section 5 shall be unaffiliated and
disinterested appraisers having at least five (5) years prior experience in
making similar rent value appraisals in the Research Triangle Park area. If
either the Landlord or the Tenant fails or refuses to select an appraiser, the
other appraiser shall alone determine the rent for the extension term in
accordance with the terms hereof. Each party shall bear the fees and expenses of
their selected appraiser and, if necessary to select a third appraiser, the
parties hereto shall equally bear the fees and expenses of that third appraiser.
The appraised rent determined pursuant to this Section 5 shall be binding upon
the parties, except that Tenant may in good faith unilaterally reject the
appraised rent determined pursuant to this Section 5 by written notice to
Landlord given at least ninety (90) days prior to the expiration of the original
term of this Lease (failure to give such notice being an absolute bar to any
right on the part of Tenant to reject such appraised rent notwithstanding
whether or not the aforesaid appraisal process has been reinitiated) but,
nevertheless, provided always that in no event may Tenant reject the appraised
rent number in bad faith or if the appraised rent number is less than the number
initially determined by the appraiser appointed by Tenant. If Tenant timely
exercises its election to reject the appraised rent determined for the extension
term in accordance with the terms hereof, then and in that event, this Lease
shall expire absolutely as of its original expiration date as if Tenant had not
exercised the option herein granted.

     6.   USE.  Tenant may use the Premises for general office purposes, but for
none other without Landlord's written consent first had and obtained.  Tenant
shall not use or occupy nor permit the Premises to be used or occupied, nor do
or permit anything to be done in or on the Premises, in a manner which may (i)
make void or voidable any insurance in force with respect thereto; (ii) result
in any increase in the premiums charged for insurance, or cause Landlord to be
unable to obtain at regular rates fire or other insurance required to be
maintained; (iii) cause structural damage to the Premises, the Building, or any
part thereof; (iv) constitute a public or private nuisance; or (v) otherwise
violate any present or future law, ordinance, rule or regulation of any public
authority, including, without limitation, any law, ordinance, rule or
requirement concerning or relating to Tenant's use, occupancy, or alteration of
the Premises.  If as the result of any act or neglect of Tenant, its employees,
agents, representatives, clients or visitors, or the manner in which business is
conducted at the Premises, any insurance rate shall be increased over the
existing rate and assessed against Landlord, then and in that event, Tenant
shall pay to Landlord on demand the amount of such increase as additional rent.

                                       9
<PAGE>
 
     So long as Tenant is not then in default under any term or condition hereof
after notice and the applicable cure period, if any, and provided further that
no permitted assignment or subleasing of this Lease to a third party has then
occurred, Landlord shall not lease any space in the Building to any "direct
competitor" of Tenant during the term of this Lease, or any extension thereof,
identified as Exhibit E, and by this reference, made a part hereof.  As used
herein, the term "direct competitor" shall mean any company or firm listed in
Exhibit E hereto.

     7.   SERVICES BY LANDLORD. Provided that Tenant is not in default hereunder
(i.e., after Landlord's notice and Tenant's failure to cure within the
applicable cure period, if any), Landlord shall cause to be furnished to the
Premises in common with other tenants during "Standard Hours of Operation" (as
defined below), Monday through Saturday (excluding Holidays), the following
services: janitorial services (once per working day after normal weekday working
hours); water if available from city mains for drinking, lavatory and toilet
purposes; operatorless elevator service; electricity for general office space
use (including fluorescent lighting replacements); trash removal in accordance
with city schedules; and heating and air conditioning for reasonably comfortable
use and occupancy of the Premises, providing heating and cooling conforming to
any governmental regulation prescribing limitations thereon shall be deemed to
comply with this service. All additional costs resulting from Tenant's
extraordinary usage of heating, air conditioning or electricity which Landlord
shall document shall be paid by Tenant, and Tenant shall not install equipment
within the Premises with unusual demands for any of the foregoing without
Landlord's prior written consent which Landlord may withhold if it determines
that in its opinion such equipment may not be safely used in the Premises or
that electrical service is not adequate therefor. Landlord shall provide free
parking in the amount of four (4) parking spaces per 1,000 useable square feet
of Premises, in common with the other tenants, for Tenant's employees and
visitors. Tenant and its employees shall have access to the Premises twenty-four
(24) hours per day, seven (7) days per week and fifty-two (52) weeks per year.
So long as Landlord acts reasonably and in good faith, there shall be no
abatement or reduction of rent by reason of any of the foregoing services not
being continuously provided to Tenant.

     Landlord agrees to provide heating and air conditioning after-hours (i.e.,
hours before or after the Standard Hours of Operation) at Tenant's request after
reasonable notice and if the area to be served is zoned for this purpose.  The
cost of after-hours service of heating or air conditioning shall be additional

                                       10
<PAGE>
 
rent payable monthly by Tenant at Landlord's actual cost plus ten percent (10%)
or $25.00 per hour, whichever is greater.

     As used herein, "Standard Hours of Operation" shall mean and refer to those
hours of operation at the Building which are 7:30 a.m. to 6:30 p.m. Monday
through Friday and 8:00 a.m. through 1:00 p.m. on Saturday, except holidays.
Holidays shall mean and refer to each of the following days (on the day set
aside for observance): New Year's Day, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day, Christmas Day and any other holiday(s) generally
recognized as such by landlords of office space in the Research Triangle Park
area office market, as reasonably determined by Landlord.

     Landlord agrees to maintain and keep in good working order the Premises,
Building and common areas and any operating equipment contained therein,
including, without limitation the cooling and heating system, the electrical
system, roof, security system, the sprinkler system, exterior walls, and the
plumbing system, and agrees to pursue, to the extent actionable, any claim
against any and all contractors, subcontractors or other firms, or persons
providing services, equipment or materials for the construction of the Building,
Premises or the common areas, to the extent such services, equipment or
materials are defective, provided, however, that, under no circumstances, shall
Landlord be liable to Tenant for any damage caused to Tenant and its property
due to the Building or any part or appurtenance thereof being improperly
constructed or being or becoming out of repair, or arising from the leaking of a
pipe, facility or system for any utility (except that nothing contained in this
sentence shall be construed to be a waiver of Tenant's rights or remedies
available to it at law or in equity).  To the extent that Landlord is held
liable to Tenant for damage caused to Tenant and its property due to the
Building or any part or appurtenance thereof being improperly constructed or
being or becoming out of repair, or arising from the leaking of a pipe, facility
or system for any utility, it is expressly agreed by the parties hereto that
Landlord shall be obligated to Tenant only to the extent of Tenant's actual
damages but not Tenant's special or consequential damages, including, without
limitation, loss of profits. Tenant shall immediately report to Landlord any
defective condition in or about the Premises known to Tenant.

     The use and occupancy by the Tenant of the Premises shall include the use
in common with others entitled thereto of the common areas, including driveways,
parking areas, service roads, loading docks, sidewalks, corridors, exterior
facade, landscaped and planted areas, and all other improvements provided by
Landlord for the common use of the Building tenants as shown on the site plan
for the Building attached as Exhibit A-3, and any

                                       11
<PAGE>
 
other common facility as may be designated from time to time by the Landlord,
subject, however, to the terms and conditions of this Lease and to the
reasonable rules and regulations for use therefor as prescribed from time to
time by the Landlord.  Tenant, its employees, agents, customers and invitees
shall have the nonexclusive use (in common with other benefitting tenants) to
use the common areas for purposes intended.  Tenant shall not at any time
interfere with the use of the common areas by Landlord, another tenant or any
other person entitled to use the same.  Landlord reserves the right, from time
to time, to alter any of the common areas, to exercise control and management of
the same, and to establish, modify, change and enforce such reasonable rules and
regulations as Landlord in its discretion may deem desirable for the management
of the Building or the common areas, provided that such actions by Landlord do
not materially and adversely interfere with Tenant's operation of, or access to,
the Premises or result in a material alteration of the terms of this Lease
adverse to Tenant.

     8.   TENANTS ACCEPTANCE AND MAINTENANCE OF PREMISES; LIENS.  Upon its
occupancy of the Premises, Tenant represents to the Landlord that Tenant has
examined and inspected the same, finds the Premises to be as represented by the
Landlord and satisfactory for Tenant's intended use, and evidences Tenant's
acceptance of the Premises on the date of such occupancy "where is" and "as is",
except for latent defects.  Tenant shall maintain (and so deliver at the end of
the Lease) each and every part of the Premises (excluding portions of the
Premises which Landlord is obligated to maintain, exterior drives, walks and
parking areas and common areas in the Building to be maintained by Landlord) in
good repair and condition, excepting only ordinary wear and tear and damage to
the Building or the Premises not caused by Tenant.  In addition, Tenant will
repair any damage occurring to the Premises as the result of Tenant's fault or
its removal of its trade fixtures or furnishings, shall make at Tenant's sole
cost and expense such restorations and repairs, in quality equivalent or better
than the original work restored or repaired, as may be required to so maintain
the same, ordinary wear and tear only excepted.  Tenant, however, shall make no
structural or interior alterations of the Premises without Landlord's prior
written consent, and any work performed by Tenant shall be done in a good and
workmanlike manner, and so as not to disturb or inconvenience other Tenants in
the Building.  Tenant shall not at any time permit any work to be performed on
the Premises except by duly licensed contractors or artisans, each of whom must
carry general public liability insurance, certificates of which shall be
furnished Landlord.  At no time may Tenant do any work that results in a claim
of lien against Landlord, and if requested by Landlord on termination of the
Lease or vacation of the Premises by Tenant, Tenant shall restore

                                       12
<PAGE>
 
at Tenant's sole expense the Premises to the same condition as existed at the
commencement of the term, ordinary wear and tear only excepted.  Landlord,
however, may elect to require Tenant to leave alterations performed by it.
Tenant shall keep the Premises and the Building free from any liens arising out
of any work performed, materials ordered or obligations incurred by or on behalf
of Tenant, and Tenant hereby agrees to indemnify and hold Landlord, its agents,
employees, contractors, officers, directors, partners, and shareholders harmless
from any liability, cost or expense for such liens.  Tenant shall cause any such
lien imposed to be released of record by payment or bonding upon terms
reasonably acceptable to Landlord within twenty (20) days after the earlier of
the imposition of the lien or a written request by Landlord therefor.  If Tenant
fails to remove any lien within the prescribed twenty (20) day period, then
Landlord may do so at Tenant's expense, including costs and attorneys' fees,
which expense shall be due as additional rent hereunder.

     9.   TENANT IMPROVEMENTS. Final Tenant Improvement Plans and Specifications
showing tenant improvements to be constructed at the Premises (the "Tenant
Improvements") shall be delivered to Landlord for its review and approval on or
before February 24, 1995, and upon such Landlord approval, attached as Exhibit C
to this Lease and made a part hereof. Any and all Tenant Improvements and other
Tenant upfit of any kind whatsoever, and all plans and specifications relating
thereto, shall require the prior approval of the Landlord which approval shall
take into account the quality and first-class character of the Building, but
shall not be unreasonably withheld. At Tenant's cost and expense but
nevertheless subject to the Tenant Allowance as provided below, Landlord agrees
to cause the Tenant Improvements at the Premises to be substantially completed
on or before June 1, 1995, the projected commencement date (subject to the
aforementioned ninety (90) day grace period as set forth in Section 2, above,
and otherwise in accordance with the terms and conditions of that Section 2).
The parties hereto agree to cooperate fully in connection with the construction
of Tenant Improvements. Landlord agrees to procure at least two (2) competing
bids on a negotiated bid basis for the construction of the Tenant Improvements
at the Premises. Landlord will choose the lower cost estimate, unless Tenant
authorizes the Landlord to choose a higher bid. Landlord agrees to review all
bids received with Tenant. Landlord will then contract with a contractor
pursuant to a guaranteed maximum price contract, subject to adjustment in
contract price by change order only. As used herein, the term substantial
completion with respect to construction of the Tenant Improvements is that date
when the Premises is "suitable for occupancy," as defined in Section 2, above.
With respect to completed work of the Tenant Improvements

                                       13
<PAGE>
 
at the Premises, the Premises shall be clean and free or any debris or
obstruction.  Floors to receive carpeting are to be cleaned, leveled and sealed.
When Landlord determines the Tenant Improvements to be substantially complete,
the Landlord and Tenant will prepare a list of items to be corrected or
completed (i.e., the punch list), which punch list shall be completed within not
later then thirty (30) days of Tenant's occupancy of the Premises.  If for any
reason, but nevertheless in accordance with the terms of Section 2, the Premises
together with the Tenant Improvements is delivered by Landlord after June 1,
1995, no rent shall be due until such time as the possession to the Premises is
delivered in a condition "suitable for occupancy."  Upon such delivery of the
Premises by Landlord, Tenant shall be obligated to occupy the Premises within a
commercially reasonable period of its written notice from Landlord of the
availability of the Premises in a condition "suitable for occupancy," subject
only to Tenant's right of cancellation as set forth in Section 2.

     Provided Tenant is not in default hereunder (after Landlord's notice and
Tenant's failure to cure within the applicable cure period), Landlord agrees to
provide Tenant an allowance of Fifteen and 50/100 Dollars ($15.50) per useable
square foot at the Premises [which tenant allowance if determined with reference
to currently estimated useable footage at the Premises is Eighty One Thousand
Five Hundred Forty-Six and 0/100 Dollars ($81,546.00)] (the "Tenant Allowance").
The Tenant Allowance may be used to offset the cost of Tenant Improvements
and/or any other Tenant cost arising during the term of this Lease after the
actual commencement date, as Tenant shall reasonably determine.  The Tenant
Allowance shall be either credited by Landlord as against cost of the Tenant
Improvements or as invoices are presented by Tenant to Landlord for any other
permitted Tenant cost.  Disbursement of the Tenant Allowance shall be subject to
the reasonable requirements of Landlord which requirements shall reasonably
relate to and concern the Tenant Improvements or Tenant's occupancy of the
Premises.

     Landlord will charge Tenant fees not to exceed in total four percent (4%)
of the Tenant Improvement costs as a construction and overhead fee with respect
to the construction of Tenant Improvements.  These Landlord fees chargeable to
Tenant may be deducted by Landlord from the Tenant Allowance, and if not so
deducted, are payable within thirty (30) days of substantial completion of the
Tenant Improvements.

     No part of the Tenant Improvements shall be of such a nature that they will
require changes outside the Building.  The plans and specifications for the
Tenant Improvements as approved by the parties or the resulting Tenant
Improvements shall not adversely affect the legality of use or occupancy of the
Building or result

                                       14
<PAGE>
 
in increases cost of fire insurance for the Building, and shall comply with
applicable law as of the date of delivery.

     Tenant and any of its representatives or consultants shall have access to
the Premises and Building during the construction of the Tenant Improvements and
any other Tenant upfit, and the right to inspect the same.

     10.  CASUALTY DAMAGE.  If the Premises are destroyed by fire or other
casualty not resulting from the wrongful or negligent act of Tenant, either
Landlord or Tenant may by written notice given not later than thirty (30) days
after the date of such destruction, terminate this Lease, in which event rent
paid for the period beyond the date of destruction shall be refunded to Tenant.
If there is not total destruction and Tenant reasonably is required to close its
operations during repairs, rent shall abate while so closed, but if Tenant is
able to continue its operations during repairs, rent shall be adjusted and
prorated in the proportion which the area of unusable leased space bears to the
total Premises, provided that Landlord shall not in any event have any liability
for losses claimed by Tenant.  If there is not total destruction, but if the
damages are such that subject to confirmation (at Tenant's written request
within five (5) business days of the date of damages) by a qualified unrelated
third party architect (mutually selected by the parties, but at Tenant's sole
cost and expense), Landlord concludes that restoration cannot be completed
within one hundred and twenty (120) days of the date on which the damages
occurred, Landlord or Tenant may, at their respective options, by written notice
given to the other not later then thirty (30) days after the date of such
damage, terminate this Lease.  Subject to confirmation of the feasibility of
restoration of the Premises within one hundred twenty (120) days on the same
terms as aforesaid and subject nevertheless to the availability of adequate
insurance proceeds therefor, Landlord shall then undertake and complete the
restoration of damage to the Premises.  If restoration as aforesaid is
undertaken, Landlord shall proceed with reasonable diligence and without delay
to cause the Premises or the Building, as the case may be, to be repaired and
restored within one hundred twenty (120) days of the date on which the damage
occurred to substantially the same condition in which it was prior to a fire or
other casualty.  If such restoration or repair is not substantially completed
within such one hundred and twenty (120) day period, then provided that Landlord
has acted continuously and diligently to effect and complete such restoration
and repair, Landlord shall be entitled to a sixty (60) day grace period in which
time to complete the restoration or repair, and thereafter (or if Landlord has
not continuously and diligently acted to restore or repair within the aforesaid
one hundred twenty (120) day period), either party may elect

                                       15
<PAGE>
 
promptly, i.e. within ten (10) business days of the last day of the aforesaid
sixty (60) day grace period or the aforesaid one hundred twenty (120) day
period, (as the case may be) to cancel this Lease by written notice to other
(and Landlord's lender, as the case may be).  Notwithstanding any other
provision contained herein to the contrary, if the Premises are damaged by cause
due to fault or neglect of Tenant, its agents, employees, invitees, or
licensees, Landlord shall have no obligation to Tenant of any kind whatsoever
with respect to any duty to restore or repair the Premises, Landlord may proceed
to restore such damage without prejudice to its right to make claim against
Tenant, its agents, employees, invitees or licensees, to the extent that
Landlord's loss is not covered by insurance proceeds, and there shall be no
apportionment or abatement of rent.

     11.  ASSIGNMENT AND SUBLEASING.  Tenant may not assign, transfer, mortgage
or encumber this Lease, and may not sublet any part or all of the Premises
without the written consent of Landlord first had and obtained, which consent
shall not be unreasonably withheld or delayed.  Any assignment or sublease to
which Landlord may consent (one consent not being any basis to contend that
Landlord should consent to a further change) shall not relieve Tenant of any of
its obligations hereunder.  The sale of Tenant to a third party shall be deemed
a voluntary assignment of this Lease and subject to the provisions of this
paragraph.  Acceptance of rent by Landlord after any non-permitted transfer or
assignment shall not constitute approval thereof by Landlord.  In no event shall
this Lease be assignable by operation of any law, and Tenant's rights hereunder
may not become, and shall not be listed by Tenant as an asset under any
bankruptcy, insolvency or reorganization proceedings.  Tenant is not, may not
become, and shall never represent itself to be an agent of Landlord, and Tenant
expressly recognizes that Landlord's title is paramount, and that it can do
nothing to affect or impair Landlord's title.  If this Lease shall be assigned
or the Premises or any portion thereof sublet by Tenant at a rental that exceeds
the rentals to be paid to Landlord hereunder, attributable to the Premises or
that portion thereof so assigned or sublet, as the case may be, then and in such
an event, one half of such  excess rent shall be paid over to Landlord by Tenant
as additional rent hereunder.

     12.  TENANT'S COMPLIANCE; INSURANCE REQUIREMENTS; WAIVER OF SUBROGATION.
Tenant shall comply with all applicable laws, ordinances and regulations
affecting Tenant and Tenant's use of the Premises, including reasonable rules
for tenants as may be developed from time to time by Landlord and personally
delivered to Tenant at the Premises.  Tenant shall maintain and care for its
personal property located in the Premises, fully insure such personal property,
and shall neither have nor make any claim against Landlord for any loss or
damage to the same except for

                                       16
<PAGE>
 
any loss or damage suffered as a direct result of Landlord's gross negligence,
willful misconduct or Landlord's default under this Lease after written notice
from Tenant and the reasonable opportunity to cure, and then only to the extent
that such loss or damage is not covered by insurance proceeds.  Throughout the
term of this Lease, Tenant shall, at its sole cost and expense, keep or cause to
be kept for the mutual benefit of Landlord and Tenant the following insurance:
(a) commercial general liability insurance naming the Landlord as an additional
insured against any and all claims for bodily injury and property damage
occurring in, or about the Premises, arising out of Tenant's use and occupancy
of the Premises, such insurance to have a combined single limit of not less than
$1,000,000 per occurrence with a $2,000,000 aggregate limit and excess umbrella
liability insurance in the amount of $2,000,000, and such insurance to be
primary and non-contributing to any insurance available to Landlord and
Landlord's insurance shall be in excess thereto, and in no event shall the
limits of such insurance be considered as limiting the liability of Tenant under
this Lease; (b) personal property insurance insuring all equipment, trade
fixtures, inventory, fixtures and personal property located on or in the
Premises for perils covered by the causes of loss--special form (all risk),
together with coverage for flood, earthquake and boiler and machinery (if
applicable), such insurance to be written on a replacement cost basis in an
amount equal to one hundred percent of the full replacement value of the
aggregate of the foregoing property; (c) workers' compensation insurance in
accordance with statutory law and employers' liability insurance with a limit of
not less than $100,000 per employee and $500,000 per occurrence; and (d) such
other necessary insurance as required by law or by customary commercial practice
locally applied. The policies required to be maintained by Tenant shall be with
companies rated AX or better in the most current issue of Best's Insurance
Reports.  Insurers shall be licensed to do business in the State of North
Carolina and domiciled in the United States of America.  Any deductible amounts
under any insurance policies required hereunder shall not exceed $15,000.00
except for $50,000.00 for flood casualty and 5% of value for earthquake
casualty.  Certificates of Insurance (or certified copies of the policies if
required by Landlord) shall be delivered to Landlord prior to the commencement
date and thereafter at least thirty (30) days prior to the expiration date of
the old policy.  Tenant shall have the right to provide insurance coverage which
it is obligated to carry pursuant to the terms hereof in a blanket policy,
provided such blanket policy expressly affords coverage to the Premises and to
Landlord directly as required by this Lease.  Each policy of insurance shall
provide notification to Landlord at least thirty (30) days prior to any
cancellation or modification resulting in a reduction of insurance coverage.
Throughout the term of the

                                       17
<PAGE>
 
Lease, Landlord shall carry (i) all-risk ninety percent (90%) replacement cost
fire and extended coverage insurance (including earthquake and flood coverage
under such extended coverage) on the Building and the common area facilities
used in connection with the Building (except that a full replacement cost
standard shall apply to any successor of Landlord), (ii) comprehensive general
liability insurance with respect to all common areas of the Building in an
amount not less than that required of Tenant with respect to the Premises; and
(iii) workers' compensation and employer's liability insurance in accordance
with statutory requirements. With respect to the Landlord's insurance, the same
deductible amounts as aforesaid shall apply. Notwithstanding anything in this
Lease to the contrary, to the extent covered by insurance, Landlord releases and
waives unto Tenant, its successors and assigns, and Tenant releases and waives
unto Landlord, its successors and assigns, all right to claim damages for any
injury, loss, cost, or damage to persons or to the Premises which is occasioned
by fire, explosion, accident, occurrence or condition in, or about the Premises
or any other casualty, as long as the amount of which injury, loss, cost or
damage has been paid either to Landlord, Tenant, or any other person, firm or
corporation, under the terms of any fire, extended coverage, public liability or
other policy of insurance, to the extent such releases or waivers are permitted
under applicable law. All policies of insurance carried or maintained pursuant
to this Lease shall contain or be endorsed to contain a provision whereby the
insurer waives all rights of subrogation against both Tenant and Landlord, as
the case may be, provided such a provision shall be obtainable. If insurance
policies with such waiver of subrogation provisions shall not be obtainable then
the provisions relating to waiver of subrogation as contained in this Section 12
shall have no effect during such time as such insurance policies with waiver of
subrogation provisions shall not be obtainable. If any provision relating to a
waiver of subrogation, as set forth in this Section 12 shall contravene any
present or future law with respect to exculpatory agreements, the liability of
the party affected shall be deemed not released but shall be secondary to the
other's insurer.

    13.  SUBORDINATION; ATTORNMENT.  Tenant agrees that this Lease will either
be subordinate or superior to any mortgage heretofore or hereafter executed by
the Landlord covering the Premises, depending on the requirements of such
mortgagee.  On request, Tenant will execute such agreements making this Lease
superior or subordinate as Landlord's mortgagee may request, and will agree to
attorn to said mortgagee providing the mortgagee agrees not to disturb Tenant's
possession hereunder so long as Tenant is in compliance with this Lease.
Landlord consents to Tenant's execution of Landlord's mortgagee's subordination,
attornment and non-disturbance agreement, and to be bound by the

                                       18
<PAGE>
 
provisions thereof.  Further Tenant agrees to execute within fifteen (15) days
of request therefor, and as often as reasonably requested, estoppel certificates
setting forth the facts with respect to date of occupancy, termination date of
this Lease, the amount of rent due and date to which rent is paid, whether or
not it has any known defense or offsets to the enforcement of the Lease or
knowledge of any default or breach by Landlord, and that this Lease is in full
force and effect except as to any modifications or amendments, copies of which
Tenant shall attach to such estoppel certificate.  Tenant agrees to attorn to
any successor of Landlord.

    14.  SIGNS.  Tenant may not erect, install or display any sign or
advertising material upon the Premises, the walls thereof, or in any window
therein, without the prior written consent of Landlord.  Landlord shall furnish,
install and maintain a building directory at a convenient location in the lobby
listing the name of Tenant and the room number of Tenant's entrance office.

    15.  ACCESS TO PREMISES.  After reasonable notice to Tenant except in the
case of an emergency, Landlord shall have the right, either itself or through
its authorized agents, to enter the Premises at all reasonable times to inspect
the same; to show them to prospective tenants (for the Premises or other space
in the Building); to allow inspection by a mortgagee; and to make such repairs,
alterations or changes as Landlord deems necessary.  Tenant, its agents,
employees, invitees and guests shall have the right of ingress and egress to
common and public areas of the Building, provided Landlord by reasonable rules
may control such access for the comfort, convenience and protection of all
tenants in the Building.  Tenant further agrees that Landlord may enter the
Premises at all reasonable times to post "For Rent" signs within six (6) months
prior to the expiration of the Lease term, which signs may not be removed by
Tenant.

    16.  DEFAULT.  If Tenant: (a) fails to pay all rent as provided in this
Lease when due and such default shall continue for two (2) business days after
Tenant's receipt of written notice from Landlord to Tenant thereof; (b) breaches
any other agreement or obligation herein set forth and such breach shall
continue for thirty (30) days after the date of written notice from Landlord to
Tenant specifying the nature of the breach (or for such lesser period if
performance is required to be made within such lesser period due to a specific
provision of this Lease), provided nevertheless that Tenant shall not be in
default if Tenant shall in good faith have commenced the curing or remedying of
such breach within such thirty (30) days period (or shorter period with respect
to a breach requiring performance within a certain time under the terms of this
Lease) and

                                       19
<PAGE>
 
thereafter shall diligently and continuously proceed therewith to completion in
full satisfaction of the breach; (c) files (or has filed against it) any
petition or action for relief under any creditor's law (including bankruptcy,
reorganization, or similar actions), either in state or federal court; or (d)
becomes insolvent, makes any transfer in fraud of creditors, has a receiver
appointed for its assets, or makes an assignment for benefit of creditors, then
in addition to any other lawful right or remedy which it may have, Landlord may
do the following:  (A) declare the rent for the balance of the term immediately
due and payable, and collect the present value of the same (determined by
discounting the rent for the remainder of the term, using the discount rate of
the Federal Reserve Bank of Richmond, Virginia existing at such time and
nevertheless subject to Landlord's duty to mitigate Tenant's damages if required
under North Carolina law); (B) without obtaining any court authorization, lock
up the Premises and deny Tenant access thereto; (C) terminate this Lease; or (D)
repossess the Premises, and with or without terminating, relet the same at such
amount as Landlord deems reasonable but nevertheless subject to Landlord's duty
to mitigate its damages, and if the amount is less than Tenant's rent, Tenant
shall immediately pay the difference on demand to Landlord, but if in excess of
Tenant's rent, the entire amount shall belong to Landlord free of any claim of
Tenant thereto.  All expenses of Landlord in repairing, restoring or altering
the Premises for reletting, together with leasing fees,  all other expenses in
seeking and obtaining a new tenant, the unamortized portion of Landlord's paid
allowance for Tenant Improvements and other permitted Tenant costs, the
unamortized portion of any other upfit costs paid on account of this Lease by
Landlord, and other damages and costs, shall be charged to and a liability of
Tenant.  Landlord's reasonable attorneys fees in pursuing any of the foregoing
remedies, or in collecting any rents due by Tenant hereunder, shall be paid by
Tenant.  All rights and remedies of Landlord are cumulative, and the exercise of
any one shall not be an election excluding Landlord at any other time from
exercising a different or inconsistent remedy.  No waiver by Landlord of any
covenant or condition shall be deemed to imply or constitute a further waiver of
the same at a later time, and acceptance of rent by Landlord even with knowledge
of a default by Tenant shall not constitute a waiver of such default.

     If Landlord breaches any agreement or obligation in this Lease, and such
breach shall continue for a period of thirty (30) days after the later dates of
respective notice to each of Landlord and Landlord's lender (to the extent
Landlord has given Tenant written notice of any such lender and the address
thereof which as of the date hereof, includes ABN-AMRO Bank, N.V. and the
Principal Mutual Life Insurance Company, c/o Principal Financial

                                       20
<PAGE>
 
Group, 711 High Street, Des Moines, Iowa 50392 Attn: Mr. Frank Schmitz,
Commercial Real Estate (Loan No. 750506)), provided nevertheless, that Landlord
shall not be in default if Landlord or Landlord's lender, as the case may be
(each having rights of cure hereunder) shall severally (but not necessarily
jointly) in good faith have commenced the curing or remedying of such breach
within such thirty (30) day period and thereafter shall diligently and
continuously proceed therewith to completion in full satisfaction of the breach,
then in addition to any other lawful right or remedy which it may have, Tenant
shall have the option of curing the default and deducting the reasonable costs
of cure from current and future rent due.

     In the event that either Landlord or Tenant brings an action at law or in
equity for the enforcement of any provision of this Lease, the non-prevailing
party in such action shall pay to the prevailing party its reasonable attorney's
fees and costs.

     17.  INDEMNIFICATIONS.  Except for claims caused by the negligence or
willful misconduct of Landlord, Tenant shall indemnify and hold harmless
Landlord, its agents, representatives, successors or assigns, from and against
any and all losses, damages, liabilities, claims, penalties, costs or expenses
(including attorney's fees), whether caused by Tenant or by its agents,
servants, employees, independent contractors or licensees, occasioned by,
arising or resulting from or growing out of (a) Tenant's use or occupancy of the
Premises, or from the conduct of Tenant's business, or from any activity, work
or things done, permitted or suffered by Tenant in or about the Premises; (b)
the breach or default in the performance of any obligation on Tenant's part to
be performed under the terms of this Lease or arising from any act or omission
of the Tenant; or (c) any violation of any Environmental Law (as defined below),
any unsafe or improper use or storage of any Hazardous Substance (as defined
below) or any condition created by or arising therefrom including any pollution
or contamination at or about the Premises or the Building, arising from any act
or omission of Tenant, its agents, servants, employees, contractors or
licensees, whether or not due to negligence, an omission or a willful act.

       Tenant shall defend any suit, action or proceeding commenced or brought
against Landlord in connection with any indemnity or obligation of Tenant
contained in this Section regardless of any alleged fault or cause and Tenant
shall employ legal counsel reasonably satisfactory to Landlord to defend such
suits, actions or proceedings.  Tenant shall deliver to Landlord copies of the
documents served in any such suit, action or proceeding and, whenever requested
by Landlord, shall advise as to the status of such suit, action or proceeding.
If Tenant

                                       21
<PAGE>
 
fails to defend diligently any such suit, action or proceeding, or if Landlord
elects to defend by written notice to Tenant at any time, Landlord shall have
the right (but not the obligation) to defend the same at Tenant's expense.
Tenant shall not settle any such suit, action or proceeding without Landlord's
prior written consent.  Tenant shall give timely notice of such suit, action or
proceeding and the claims thereof to Landlord and each insurer issuing an
insurance policy required under this Lease.

     Except for claims caused by the negligence or willful misconduct of Tenant
or Tenant's agents, servants, employees, contractors, licensees or invitees,
Landlord shall indemnify and hold Tenant harmless from and against any claims
arising out of (i) any breach or default by Landlord in the performance of any
of its obligations under this Lease; or (ii) the negligence or willful
misconduct of Landlord or its agents; and in each case from and against any and
all damages, losses, liabilities, lawsuits, costs and expenses (including
reasonable attorneys' fees) arising or resulting therefrom.  If such action is
brought against Tenant, Landlord upon notice from Tenant shall defend the same
through counsel selected by Landlord's insurer or other counsel in each case
acceptable to Tenant.

     The indemnification provisions contained herein shall not be deemed to be
limited by the limits of any insurance policies required under this Lease and
shall survive the expiration or termination of this Lease.

   18.    CONDEMNATION.  If all of the Premises or such part thereof or part of
the common areas (including those common areas within the Building), as will
make the Premises unusable for the purposes contemplated by this Lease, be taken
under the power of eminent domain (or a conveyance in lieu thereof), then this
Lease shall terminate as of the date possession is taken by the condemnor, and
rent shall be adjusted between Landlord and Tenant as of such date.  If only a
portion of the Premises is taken and Tenant can continue use of the remainder,
then the Lease will not terminate, but rent shall abate in a just and
proportionate amount to the loss of use occasioned by the taking (and Landlord
shall repair any damage to the Premises and/or the Building caused by such
condemnation to the extent of the award received by Landlord).  Tenant shall
have no right or claim to any part of any award made to or received by the
Landlord for any taking and no right or claim for any alleged value of the
unexpired portion of this Lease; provided, however, that Tenant shall not be
prevented from making a claim against the condemning party (but not against
Landlord) for any moving expenses, loss of profits, or taking of Tenant's
personal property (other than its leasehold interest) or improvements installed
in the Premises by Tenant to which Tenant may be entitled.

                                       22
<PAGE>
 
   19.    QUIET ENJOYMENT.  If Tenant promptly and punctually complies with each
of its obligations hereunder, it shall peacefully have and enjoy the possession
of the Premises during the term hereof; provided that no action of Landlord in
repairing or restoring the Premises or concerning work in other space of the
Building shall be deemed a breach of this covenant, or give Tenant any right to
modify this Lease either as to term, rent or sums payable, or other obligations
to be performed except as may be expressly set forth in other Sections of this
Lease.

   20.    SECURITY DEPOSIT.  Landlord acknowledges receipt from Tenant of the
sum of Eight Thousand Two Hundred Fifty Eight and 25/100 Dollars ($8,258.25),
which sum Landlord shall retain as security for the performance by Tenant of
each of its obligations hereunder.  If Tenant fails at any time to perform its
obligations, Landlord may at its option apply said deposit, or so much thereof
as is required, to cure Tenant's default, but if prior to the expiration or
termination of this Lease Landlord depletes said deposit in whole or in part,
Tenant shall immediately restore the amount so used by the Landlord.  This
deposit shall not bear interest, and unless the Landlord uses the same to cure a
default of Tenant, or to restore the Premises to the condition that Tenant is
required to leave them at the conclusion of the term, Landlord shall within
thirty (30) days of the expiration of the Lease refund to Tenant so much of the
deposit as remains.

   21.    NOTICES.  Any notices which Landlord or Tenant is required or desires
to give the other shall be deemed sufficiently given or rendered if, in writing,
is delivered personally or sent by regular mail, or if an event of default is
claimed, then either delivered personally or sent by certified or registered
mail, postage prepaid, to the address listed after the signature of the party to
be given notice, at the end of this Lease document.  Any notice given herein
shall be deemed delivered when the return receipt therefore is signed, or
refusal to accept the mailing by the addressee is noted thereon by the postal
authorities.

   22.    [INTENTIONALLY OMITTED]

   23.    LANDLORD LIABILITY.  Tenant agrees that Landlord shall not be liable
for (i) injury to Tenant's business or any loss of income therefrom or for any
damage to any goods, wares, merchandise, or other property of Tenant, or
Tenant's contractors, agents, employees, invitees, customers or any other person
in or about the Premises, except to the extent that such injury or damage is
caused by the gross negligence or willful misconduct of Landlord, its agents or
employees but subject nevertheless to the limitation that Tenant's measure of
damages

                                       23
<PAGE>
 
shall be Tenant's actual damages, and not special or consequential damages,
including, without limitation, loss of profits,  or (ii) injury to the person of
the Tenant or to the Tenant's contractors, agents, employees, invitees or
customers whether such damage or injury is caused by or results from fire,
steam, electricity, gas, water or rain, or from the breakage, leakage,
obstruction or other defects of pipes, sprinklers, wires, appliances, plumbing,
air conditioning or lighting fixtures or from any other cause, whether said
damage or injury results from conditions arising upon the Premises or upon other
portions of the Building of which the Premises are a part or from other sources
or places, and regardless of whether the cause of such damage or injury or means
of repairing the same is inaccessible to Tenant except to the extent that such
injury or damage is caused by the gross negligence or willful misconduct of
Landlord, its agents or employees but subject nevertheless to the limitation
that Tenant's measure of damages shall be Tenant's actual damages, and not
special or consequential damages, including, without limitation, loss of
profits.  Landlord shall not be liable for any loss or damages arising from any
act or neglect of any other tenant.  The term "Landlord" as used in this Lease
so far as covenants or obligations on the part of Landlord are concerned shall
be limited to mean and include only the owner or owners of the Premises and
Building at the time in question, and in the event of any transfers or
conveyances the then grantor shall be automatically freed and released from all
liability as respects the performance of any covenant or obligation contained in
this Lease on the part of Landlord to be performed from and after the date of
such transfer or conveyance, and this Lease and its terms shall be binding on
the Landlord, its successors and assigns only during and in respect to their
respective successive periods of ownership.  Notwithstanding any other provision
contained herein to the contrary, in the event of a breach hereof by Landlord or
the failure of Landlord to perform any of its obligations hereunder, Landlord
shall have no personal liability therefor, but Tenant shall look solely to
Landlord's interest in the Premises for satisfaction of any claim or loss.

   24.    SURRENDER; HOLDING OVER. Tenant will vacate and deliver up the
Premises and all improvements, additions and alterations thereto (except Tenant
equipment, personal property and trade fixtures installed by Tenant at its
expense which may be removed by Tenant) at the expiration or sooner termination
of this Lease, in a good, clean and tenantable condition as the same were at the
beginning of Tenant's occupancy, excepting reasonable wear, damage by fire and
other casualty or appropriation by eminent domain. All Tenant equipment,
personal property and trade fixtures necessary or convenient for Tenant's
business which shall have been supplied or installed at the expense of Tenant,
shall remain Tenant's property. Tenant may remove its

                                       24
<PAGE>
 
equipment, personal property and trade fixtures installed by Tenant at its
expense which may be removed by Tenant) at the expiration or sooner termination
of this Lease, in a good, clean and tenantable condition as the same were at the
beginning of Tenant's occupancy, excepting reasonable wear, damage by fire and
other casualty or appropriation by eminent domain.  All Tenant equipment,
personal property and trade fixtures necessary or convenient for Tenant's
business which shall have been supplied or installed at the expense of Tenant,
shall remain Tenant's property.  Tenant may remove its equipment, personal
property and trade fixtures within five (5) days after the expiration or sooner
termination of this Lease, provided (a) Tenant is not then in default hereunder
after notice and the applicable cure period, if any; (b) removal of the Tenant
item can be accomplished without damage to the Premises, or such damage is
repaired in accordance with the terms of Section 8, above; and (c) Tenant
immediately repairs (or reimburses Landlord for the cost of repairing) any
resulting damage or defacement.  Tenant shall not acquire any right or interest
in the Premises by remaining in possession after the expiration of this Lease.
Any such holding over shall not be deemed to be a renewal of this Lease but
shall be deemed to create a tenancy-at-sufferance under which Tenant occupies
the Premises without the consent of Landlord.  By such holding over, however,
Tenant shall nevertheless be deemed to have agreed to be bound by all of the
terms and conditions of this Lease except those as to the term hereof and the
rent then due shall be payable at a rate equal to One Hundred and Fifty Percent
(150%) of the rate of rent existing at the end of this Lease, together with any
additional rent payable hereunder.

   25.    HAZARDOUS MATERIALS; ENVIRONMENTAL COMPLIANCE.

     A.  Tenant's Responsibility.  Tenant shall not (either with or without
         -----------------------                                           
negligence) cause or permit the escape, disposal or release of any hazardous
substances or materials in, under or around the Premises, the Building or the
office park identified in Exhibit A-3.  Tenant shall not allow the storage or
use of said substances or materials in any manner not sanctioned by law or by
the highest standards prevailing in the industry for the storage and use of such
substances or materials, nor allow to be brought into the Building or the park
identified in Exhibit A-3 any such materials or substances except to use in the
ordinary course of Tenant's business, and then only after written notice is
given to Landlord of the identity of such substances or materials (except that
no such notice shall be required with respect to commonly used office supplies
and cleaning products).  Tenant covenants and agrees that Tenant will for itself
and its agents, employees, servants, contractors or invitees (as used in this
Section 25, collectively the "Tenant") comply with all now existing or hereafter
enacted or issued statutes, laws, rules, ordinances, orders, permits, and
regulations of all state, federal, local, and other governmental and regulatory
authorities, agencies, and bodies applicable to the Premises, pertaining to
environmental matters, or regulating, prohibiting or otherwise having to do with
asbestos and all other toxic, radioactive, or hazardous wastes or materials
including, but not limited to, the Federal Clean Air Act, the Federal Water
Pollution Control Act, and the Comprehensive Environmental Response,
Compensation, and Liability Act of 1980, as from time 

                                       25
<PAGE>
 
to time amended (all hereinbefore and hereinafter collectively called the
"Environmental Laws" or "Laws").

     B.  Tenant's Liability.  In addition to the indemnifications contained in
         ------------------                                                   
Section 17 hereof, Tenant shall hold Landlord free, harmless, and indemnified
from any penalty, fine, claim, demand, liability, cost, or charge whatsoever
which Landlord shall incur, or which Landlord would otherwise incur, by reason
of Tenant's failure to comply with this Section 25, including, but not limited
to: (i) the cost of bringing the Premises into compliance with all Laws; (ii)
the reasonable cost of all appropriate tests and examinations of the Premises to
confirm that the Premises have been brought into compliance with all Laws; and
(iii) the reasonable fees and expenses of Landlord's attorneys, engineers, and
consultants incurred by Landlord in enforcing and confirming compliance with
Section 25.

     C.  Property.  For the purposes of this Section 25, the Premises shall
         --------                                                          
include the Premises identified in Section 1 above, together with the real
estate covered within the Site Plan, Exhibit A-3 and all structures and
improvements thereon; all personal property used in connection with the Premises
(including that owned by Tenant); and the soil, ground water, and surface water
of the Premises, as this term is defined in this Subsection 25(C).

     D.  Inspections by Landlord.  Landlord and its engineers, technicians, and
         -----------------------                                               
consultants (collectively the "Auditors") may, from time to time as Landlord
reasonably deems appropriate but after notice during reasonable hours, conduct
periodic tests and examinations ("Audits") of the Premises to confirm and
monitor Tenant's compliance with this Section 25.  Such Audits shall be
conducted in such manner as to minimize the interference with Tenant's permitted
activities on the Premises; however, in all cases, the Audits shall be of such
nature and scope as shall be reasonably required by then existing technology to
confirm Tenant's compliance with this Section 25.  Tenant shall fully cooperate
with Landlord and its Auditors in the conduct of such Audits.  The cost of such
Audits shall be paid by Landlord unless an Audit shall disclose a material
failure of Tenant to comply with this Section 25, in which case the cost of such
Audit, and the cost of all subsequent Audits made during the Lease term and
within thirty (30) days thereafter (not to exceed two (2) such Audits per
calendar year) shall be paid for on demand by Tenant.

     E.  Landlord's Liability.  Provided, however, the foregoing covenants and
         --------------------                                                 
undertakings of Tenant contained in this Section 25 shall not apply to any
condition or matter:  (i) which existed prior to the commencement of Tenant's
use or occupancy of the Premises and was not caused, in whole or in part, by
Tenant or 

                                       26
<PAGE>
 
Tenant's agents, employees, officers, partners, contractors, representatives or
invitees; or (ii) to the extent such condition or matter is caused by, or
results from, the acts or neglects of Landlord or Landlord's agents, employees,
officers, partners, contractors, representatives or invitees, other tenants in
the Building, or third parties.

     F.  Tenant's Liability After Termination of Lease.  The covenants contained
         ---------------------------------------------                          
in this Section 25 shall survive the expiration or termination of this Lease,
and shall continue for so long as Landlord and its successors and assigns may be
subject to any expense, liability, charge, penalty, or obligation against which
Tenant has agreed to indemnify Landlord under this Section 25.

   26.  BROKERS COMMISSIONS.  Tenant represents and warrants that it has not
had dealings with any real estate broker, finder or other person, with respect
to this Lease in any manner, except Tri-Properties, Inc. and J.M. Kane & Co.,
whose address is Post Office Box 13163, Raleigh, North Carolina.  Landlord shall
pay any commissions or fees that are payable to the above-named broker or finder
with respect to this Lease (and shall indemnify and hold Tenant harmless from
Landlord's failure to pay such fees).  Tenant shall indemnify and hold Landlord
harmless from any and all damages resulting from any claims that may be asserted
against Landlord by any other broker, finder or other person, with whom Tenant
has or purportedly has dealt.  The provisions of this Section 26 shall survive
the termination or expiration of this Lease.

   27.  MISCELLANEOUS.  Headings of sections are for convenience only and
shall not be considered in construing the meaning of the contents of such
sections.  The invalidity of any portion of this Lease shall not have any effect
on the balance hereof.  This Lease shall be binding upon the respective parties
hereto and upon their heirs, executors, successors and assigns.  This Lease
supersedes and cancels all prior negotiations between the parties, and changes
shall be in writing signed by the party affected by such change.  Landlord
reserves the right to make and change from time to time rules it deems
appropriate for the common use and benefit of all tenants, with which rules
Tenant shall comply, but nevertheless provided that such rules change does not
materially and adversely alter the terms of this Lease.  Landlord may sell the
Premises without affecting the obligations of Tenant hereunder.  This Lease may
not be recorded without Landlord's prior written consent.  The singular shall
include the plural, and the masculine, feminine or neuter includes the other.
Any agreed to measurement of space shall be done in accordance with Building
Owner and Managers Association ("BOMA") standards used to determine "rentable"
square feet for office building 

                                       27
<PAGE>
 
space (either on a single tenant or multi-tenant floor basis, as the case may
be). Each of the Landlord and Tenant respectively represent that each has the
lawful authority to enter into this Lease and by signing it in their name as set
forth below, to be legally bound in accordance with its terms and conditions. No
failure by Landlord to insist upon the strict performance or observance of any
term or condition of this Lease, or to seek redress or to exercise any right or
remedy after any such failure or breach hereof, shall constitute a waiver of any
such term, condition, obligation, right or remedy, or any such failure or breach
then or thereafter occurring. No term, condition or obligation of this Lease to
be performed or observed by Tenant shall be waived, altered or modified except
by a writing executed by Landlord. No waiver of any failure, breach or default
hereof shall affect or alter this Lease, but each and every term, condition and
obligation of this Lease shall continue in full force and effect with respect to
any other failure, breach or default. This Lease, and the rights and obligations
of each of the Landlord and Tenant hereunder shall be governed by and construed
in accordance with the laws of the State of North Carolina.

   28.  SPECIAL CONDITIONS, EXHIBITS AND ADDENDA.  The following special
conditions, if any, shall apply, and where in conflict with earlier provisions
in this Lease shall control.  If any Lease Exhibits or Addenda are noted below,
such exhibits and addenda are incorporated herein and made a part of this Lease.

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

   If, during the term of this lease, the leased premises shall be destroyed or
damaged, or partially destroyed or damaged, to such a limited extent that the
repair of such destruction or damage and restoration of said premises to the

such destruction or damage and first cause said premises to be restored to the
operable condition for which the said premises were being used at the time of

their condition prior to the event causing the destruction or damage, provided,
however, if such repair and restoration cannot be accomplished, with reasonable

upon completion of such repair and restoration, then the Lessor shall be
privileged to elect not to so repair and restore, or Lessee shall be privileged
to elect to terminate this lease as of the date of such damage.  If, during the
term of this lease, the leased premises shall be destroyed or damaged, or
partially destroyed or damaged, to such an extent that the repair of such
destruction or damage and the restoration of said premises to the operable
condition for which the said premises were being used at the time of the

ninety (90) days after such destruction or damage, then Lessor shall promptly
notify Lessee in writing of such fact, and Lessee shall have the sole right,
during a period of thirty (30) days following such notification, to terminate
this lease by written notice to Lessor declaring this lease to be terminated
upon receipt by Lessor of such notice.  For purposes of rental payments, such

day period as hereinabove provided or shall notify the Lessor in writing of its
election not to terminate this lease, then the Lessor shall promptly repair such
destruction or damage and cause said premises to be restored to substantially
their condition prior to the event causing the destruction or damage, provided,
however, if such repair and restoration cannot be accomplished in time for the
term of the lease to have at least one (1) year to run upon completion of such
repair and restoration, then the Lessor shall provide written notice to Lessee
and then Lessor shall be privileged to elect not to so repair and restore, or
Lessee shall be privileged to elect to terminate this lease as of the date of
such destruction or damage.  In the event that the extent of damages are such
that the Lessor cannot repair them within a period of ninety (90) days, either
party shall be privileged to cancel the within lease.  If this lease shall
terminate as provided in this Article, Lessor shall refund to Lessee all sums
received by Lessor as rent or deposit under this lease in excess of rent due

   During any period of time that repairs are being made as aforesaid, and
Lessee is unable to use the premises for the purposes intended, the rental
payments due during the period of such repairs shall be abated in proportion to
the loss of use of the premises by Lessee. Lessee's reasonable determination in
this respect shall be final. If this lease shall terminate as provided in this
Article, Lessor shall refund to Lessee all sums received by Lessor as rent or
deposit under this lease in excess of rent due through the date of such
termination, which rent due for any part of a month to be determined by

   If the whole of the leased premises or the whole of the building erected
thereon shall be taken or condemned by any competent authority for any public or
quasi-public use or purpose, then this lease shall terminate on the date when
the possession of the premises shall be required for such use or purpose.  If
any part of the building less than the whole erected on the premises shall be
taken or condemned by any competent authority for any public of quasi-public use
or purpose and the part so taken cannot be replaced at some other location on
the leased premises, within ninety (90) days after  such taking, by the exercise

after replacing the part of the building so taken at the new location of the
leased premises, suitable for use by the Lessee for the purpose for which the
said premises were being used at the time of the taking or condemnation, then
Lessee shall have the sole right to terminate this lease on the date when the
possession of the part so taken shall be required for such use or purpose.  If
the leased premises other than the building or any part of the leased premises

have the sole right to terminate this lease on the date when the possession of
the part so taken shall be required for such use or purpose.

   The taking or condemning of a portion of the leased premises adjoining the
street or road upon which the leased premises abut for the widening of said
street or road, the effect of which will be to diminish the size of the area
available for parking vehicles, shall not be construed as rendering the
remaining portion of the leased premises unsuitable for use by the Lessee for
the purpose for which the said premises were or condemnation, if Lessor shall
make suitable replacement parking available to Lessee, within a reasonable
distance, from the leased premises at no expense to Lessee.  The taking or
condemning of easements upon, in, over, and under the premises for the
installation, operation and maintenance of which will not adversely affect the
use of the buildings on the leased premises, shall likewise not be construed as
rendering the remaining portion of the leased premises unsuitable for the use of
the Lessee for the purpose for which the said premises were being used at the
time of the taking or condemnation and there shall be no reduction in rent
because of said taking.  The taking or condemnation of easements upon or over
the premises for aviation purposes, which do not affect the use of the buildings
on the leased premise shall not be construed as rendering the remaining portion
of the leased premises unavailable for the use by the Lessee for the purpose for
which the said premises were being used at the time of the taking or
condemnation and there shall be no reduction in rent because of said taking.

   If this lease shall terminate as provided in this Article, Lessor shall
refund to Lessee all sums received by Lessor as rent or deposit under this lease
in excess of rent due through the date of such termination, which rent due for

of either Lessor or Lessee to recover compensation and damage caused by
condemnation from the condemnor. It is further understood and agreed that
neither the Lessee nor Lessor shall have any rights in any award made to the
other by any condemnation authority.

against Lessee and said petition is approved in the court in which filed, or a
receiver is appointed upon adverse petition and the appointment of such receiver
is not vacated within thirty (30) days, or in the event Lessee makes an
assignment for the benefit of creditors, Lessor reserves the right to terminate
this lease forthwith and without notice if rental payments are not current.

contained, Lessor shall have the right, after thirty (30) days notice in writing

     Lessor hereby releases Lessee from all liability arising out of loss
of or damage to the leased premises caused by perils ordinarily covered under
fire and extended coverage insurance policies (including, without limitation,

or subrogation of its insurance carriers in connection with such loss or damage,
and agrees to obtain written evidence of such consent to waiver from its
insurance carriers and to supply same to Lessee on request.  Lessee hereby
releases Lessor from all liability arising out of loss or damage to property of
Lessee located on the leased premises caused by perils ordinarily covered under
fire and extended coverage insurance policies (including, without limitation,
any such loss or damage caused by the negligent or wrongful act or failure to
act of the Lessor, its employees, agents and/or representatives).  Lessee, with
the consent of its insurance carriers in connection with such loss or damage,
hereby waives all rights of subrogation of its insurance carriers in connection
with such loss or damage, and agrees to obtain written evidence of such consent
to waiver from its insurance carriers and to supply same to Lessor on request.

     Fire and extended coverage insurance is to be obtained by Lessor and the
cost in excess of One Thousand Eight Hundred Seventy-Eight and No/100
($1,878.00) Dollars for annual coverage shall be paid by Lessee in addition to
the rental provided for under Article 3 hereof.

     Lessee shall pay in addition to the rental provided for under Article 3
hereof all real property taxes and assessments levied against or assessed upon

leased premises, to the extent that such real property taxes and assessments
exceed Ten Thousand Seven Hundred Forty-Three and 26/100 ($10,743.26) Dollars
per year. Lessee shall pay all personal property taxes and assessments levied
against or assessed upon personal property belonging to Lessee and located at or
upon the leased premises. The real property taxes for the last year of occupancy
or partial occupancy by Lessee shall be paid by Lessee at 100% of total cost for
the actual period of occupancy, and Lessee also shall pay to Lessor an amount
equal to the difference between the 6% (the assessment rate, which would have
applied to the premises if this lease was not in effect on January 1st) and
10.5% (the assessment rate applicable to the premises as a result of this lease)
property tax assessment incurred by Lessor for the balance of the year.

                     DAMAGE TO OR DESTRUCTION OF PREMISES
                     ------------------------------------

     If, during the term of this lease, the leased premises shall be destroyed
or damaged,

or partially destroyed or damaged, to such a limited extent that the repair of
such destruction or damage and restoration of said premises to the operable
condition for which the said premises were being used at the time of the
destruction or damage can be accomplished with reasonable diligence, within
ninety (90) days after such destruction or damage, Lessor shall promptly repair
such destruction or damage and first cause said premises to be restored to the
operable condition for which the said premises were being used at the time of
the destruction or damage and second to substantially return the premises to
their condition prior to the event causing the destruction or damage, provided,
however, if such repair and restoration cannot be accomplished, with reasonable
diligence, in time for the term of the lease to have at least one year to run
upon completion of such repair and restoration, then the Lessor shall be
privileged to elect not to so repair and restore, or Lessee shall be privileged
to elect to terminate this lease as of the date of such damage.  If, during the
term of this lease, the leased premises shall be destroyed or damaged, or
partially destroyed or damaged, to such an extent that the repair of such
destruction or damage and the restoration of said premises to the operable
condition for which the said premises were being used at the time of the
destruction of damage cannot be accomplished, with reasonable diligence, within
ninety (90) days after such destruction or damage, then Lessor shall promptly
notify Lessee in writing of such fact, and Lessee shall have the sole right,
during a period of thirty (30) days following such notification, to terminate
this lease by written notice to Lessor declaring this lease to be terminated
upon receipt by Lessor of such notice.  For purposes of rental payments, such
termination shall be deemed to be retroactive to the date of such destruction or
damage, and any rental payments made thereafter shall be returned to Lessee.
Unless such notice of immediate termination shall be given by Lessee to Lessor
within such period, this lease shall continue in full force and effect.  In the
event the Lessee shall fail to give written notice to the Lessor of its election
to terminate this lease within the thirty (30) day period as hereinabove
provided or shall notify the Lessor in writing of its election not to terminate
this lease, then the Lessor shall promptly repair such destruction or damage and
cause said premises to be restored to substantially their condition prior to the
event causing the destruction or damage, provided, however, if such repair and
restoration cannot be accomplished in time for the term of the lease to have at
least one (1) year to run upon completion of such repair and restoration, then
the Lessor shall provide written notice to Lessee and then the Lessor shall be
privileged to elect not to so repair and restore, or Lessee shall be privileged
to elect to terminate this lease as of the date of such destruction or damage.
In the event that the extent of damages are such that the Lessor cannot repair
them within a period of ninety (90) days, either party shall be privileged to
cancel the within lease.

     During any period of time that repairs are being made as aforesaid, and
Lessee is unable to use the premises for the purposes intended, the rental
payments due during the period of such repairs shall be abated in proportion to
the loss of use of the premises by Lessee. Lessee's reasonable determination in
this respect shall be final. If this lease shall terminate as provided in this
article, Lessor shall refund to Lessee all sums received by

                                 CONDEMNATION
                                 ------------

     If the whole of the leased premises or the whole of the building erected
thereon shall be taken or condemned by any competent authority for any public or
quasi-public use or purpose, then this lease shall terminate on the date when
the possession of the premises shall be required for such use or purpose. If any
part of the building less than the whole erected on the premises shall be taken
or condemned by any competent authority for any public of quasi-public use or
purpose and the part so taken cannot be replaced at some other location on the
leased premises, within ninety (90) days after such taking, by the exercise of
reasonable diligence by the Lessor, so as to render the leased premises, after
replacing the part of the building so taken at the new location of the leased
premises, suitable for use by the Lessee for the purpose for which the said
premises were being used at the time of the taking or condemnation, then Lessee
shall have the sole right to terminate this lease on the date when the
possession of the part so taken shall be required for such use or purpose. If
the leased premises other than the building or any part of the leased premises
other than the building shall be taken or condemned by any competent authority
for any public or quasi-public use or purpose so as to render the remaining
portion of the leased premises unsuitable for use by the Lessee for the purpose
for which the said premises were being used at the time of the taking or
condemnation, then Lessee shall have the sole right to terminate this lease on
the date when the possession of the part so taken shall be required for such use
or purpose.

     The taking or condemning of a portion of the leased premises adjoining the
street or road upon which the leased premises abut for the widening of said
street or road, the effect of which will be to diminish the size of the area
available for parking vehicles, shall not be construed as rendering the
remaining portion of the leased premises unsuitable for use by the Lessee for
the purpose for which the said premises were or condemnation, if Lessor shall
make suitable replacement parking available to Lessee, within a reasonable
distance, from the leased premises at no expense to Lessee. The taking or
condemning of easements upon, in, over, and under the premises for the
installation, operation and maintenance of which will not adversely affect the
use of the buildings on the leased premises, shall likewise not be construed as
rendering the remaining portion of the leased premises unsuitable for the use of
the Lessee for the purpose for which the said premises were being used at the
time of the taking or condemnation and there shall be no reduction in rent
because of said taking. The taking or condemnation of easements upon or over the

premises for aviation purposes, which do not affect the use of the buildings on
the leased premise shall not be construed as rendering the remaining portion of
the leased premises unavailable for the use by the Lessee for the purpose for
which the said premises were being used at the time of the taking or
condemnation and there shall be no reduction in rent because of said taking.

     If this lease shall terminate as provided in this Article, Lessor shall
refund to Lessee all sums received by Lessor as rent or deposit under this lease
in excess of rent due through the date of such termination, which rent due for
any part of a month to be determined by prorating rent due for a full month on a
daily basis. Such termination, however, shall be without prejudice to the rights
of either Lessor or Lessee to recover compensation and damage caused by
condemnation from the condemnor. It is further understood and agreed that
neither the Lessee nor Lessor shall have any rights in any award made to the
other by any condemnation authority.

                             BANKRUPTCY OF LESSEE
                             --------------------

     In the event a voluntary or involuntary petition in bankruptcy is filed
against Lessee and said petition is approved in the court in which filed, or a
receiver is appointed upon adverse petition and the appointment of such receiver
is not vacated within thirty (30) days, or in the event Lessee makes an
assignment for the benefit of creditors, Lessor reserves the right to terminate
this lease forthwith and without notice if rental payments are not current.

                           ASSIGNMENT AND SUBLETTING
                           -------------------------

     Lessee shall have the right to assign this lease and to sublet the leased
premises, in whole or in part, but shall remain primarily liable to the Lessor
for Lessee's obligation to make rental payments under this lease.

     Lessor covenants that Lessee, upon paying the rent and complying with the
terms, covenants and conditions of this lease, shall and may peaceably and
quietly have, hold, and enjoy the leased premises for the term provided for in
Article 2 hereof, and including any periods of holding over pursuant to Article
2(b) hereof.

                    LESSOR'S REMEDIES UPON LESSEE'S DEFAULT
                    ---------------------------------------

     In the event of default at any time by Lessee in the payment of the rent
herein provided for or in the performance of any other of its agreements herein
contained, Lessor shall have the right, after thirty (30) days notice in
writing to Lessee, to either:

     (1)  declare the term of this lease ended and re-enter and take possession
of the leased premises, and Lessor will use its best efforts to release in a
manner to mitigate Lessee's damages, or;

     (2)  pursue any remedy whatsoever provided for by law, or;

     (3)  re-enter the leased premises and use its best efforts to relet the
same for and on account of Lessee for the then full remaining portion of the
term of this lease or for any shorter period, and to collect and receive payment
of rent therefor and apply any and all monies so received as rent to the credit
of Lessee for the rent accruing under the term of this lease, but no such
reletting shall be construed as a termination of this lease or as a release of
Lessee from Lessee's obligation to pay rent provided during the full term of
this lease, or from Lessee's obligation to perform any other covenant herein
contained, it being expressly understood and agreed that in the event of any re-
entry by Lessor, such re-entry shall not operate to terminate this lease in any
particular or alter the obligation of Lessee to perform its covenants to pay
rent pursuant to the terms hereof unless Lessor expressly so elects pursuant to
"(1)" or "(2)" above.

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

     No waiver of any breach of breaches of any provision, covenant or
condition of this lease shall be construed to be a waiver of any succeeding
breach of such provision, covenant or condition, or of any other provision,
covenant and condition, and time is of the essence for each and every provision,
covenant and condition herein contained and on the part of either Lessor or
Lessee to be done and performed.

                     DAMAGE TO OR DESTRUCTION OF PREMISES
                     ------------------------------------

   If, during the term of this lease, the leased premises shall be destroyed or
damaged, or partially destroyed or damaged, to such a limited extent that the
repair of such destruction or damage and restoration of said premises to the
operable condition for which the said premises were being used at the time of
the destruction or damage can be accomplished with reasonable diligence, within
ninety (90) days after such destruction or damage, Lessor shall promptly repair
such destruction or damage and first cause said premises to be restored to the
operable condition for which the said premises were being used at the time of
the destruction or damage and second to substantially return the premises to
their condition prior to the event causing the destruction or damage, provided,
however, if such repair and restoration cannot be accomplished, with reasonable
diligence, in time for the term of the lease to have at least one year to run
upon completion of such repair and restoration, then the Lessor shall be
privileged to elect not to so repair and restore, or Lessee shall be privileged
to elect to terminate this lease as of the date of such damage.  If, during the
term of this lease, the leased premises shall be destroyed or damaged, or
partially destroyed or damaged, to such an extent that the repair of such
destruction or damage and the restoration of said premises to the operable
condition for which the said premises were being used at the time of the
destruction of damage cannot be accomplished, with reasonable diligence, within
ninety (90) days after such destruction or damage, then Lessor shall promptly
notify Lessee in writing of such fact, and Lessee shall have the sole right,
during a period of thirty (30) days following such notification, to terminate
this lease by written notice to Lessor declaring this lease to be terminated
upon receipt by Lessor of such notice.  For

purposes of rental payments, such termination shall be deemed to be retroactive
to the date of such destruction or damage, and any rental payments made
thereafter shall be returned to Lessee.  Unless such notice of immediate
termination shall be given by Lessee to Lessor within such period, this lease
shall continue in full force and effect.  In the event the Lessee shall fail to
give written notice to the Lessor of its election to terminate this lease within
the thirty (30) day period as hereinabove provided or shall notify the Lessor in
writing of its election not to terminate this lease, then the Lessor shall
promptly repair such destruction or damage and cause said premises to be
restored to substantially their condition prior to the event causing the
destruction or damage, provided, however, if such repair and restoration cannot
be accomplished in time for the term of the lease to have at least one (1) year
to run upon completion of such repair and restoration, then the Lessor shall
provide  written notice to Lessee and then the Lessor shall be privileged to
elect not to so repair and restore, or Lessee shall be privileged to elect to
terminate this lease as of the date of such destruction or damage.  In the event
that the extent of damages are such that the Lessor cannot repair them within a
period of ninety (90) days, either party shall be privileged to cancel the
within lease.

   During any period of time that repairs are being made as aforesaid, and
Lessee is unable to use the premises for the purposes intended, the rental
payments due during the period of such repairs shall be abated in proportion to
the loss of use of the premises by Lessee. Lessee's reasonable determination in
this respect shall be final. If this lease shall terminate as provided in this
Article, Lessor shall refund to Lessee all sums received by Lessor as rent or
deposit under this lease in excess of rent due through the date of such
termination, which rent due for any part of a month to be determined by
prorating rent due for a full month on a daily basis.

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

   If the whole of the leased premises or the whole of the building erected
thereon shall be taken or condemned by any competent authority for any public or
quasi-public use or purpose, then this lease shall terminate on the date when
the possession of the premises shall be required for such use or purpose. If any
part of the building less than the whole erected on the premises shall be taken
or condemned by any competent authority for any public of quasi-public use or
purpose and the part so taken cannot be replaced at some other location on the
leased premises, within ninety (90) days after such taking, by the exercise of
reasonable diligence by the Lessor, so as to render the leased premises, after
replacing the part of the building so taken at the new location of the leased
premises, suitable for use by the Lessee for the purpose for which the said
premises were being used at the time of the taking or condemnation, then Lessee
shall have the sole right to terminate this lease on the date when the
possession of the part so taken shall be required for such use or purpose. If
the leased premises other than the building or any part of the leased premises
other than the building shall be taken or condemned by any competent authority
for any public or quasi-public use or purpose so as to render the remaining
portion of

the leased premises unsuitable for use by the Lessee for the purpose for which
the said premises were being used at the time of the taking or condemnation,
then Lessee shall have the sole right to terminate this lease on the date when
the possession of the part so taken shall be required for such use or purpose.

   The taking or condemning of a portion of the leased premises adjoining the
street or road upon which the leased premises abut for the widening of said
street or road, the effect of which will be to diminish the size of the area
available for parking vehicles, shall not be construed as rendering the
remaining portion of the leased premises unsuitable for use by the Lessee for
the purpose for which the said premises were or condemnation, if Lessor shall
make suitable replacement parking available to Lessee, within a reasonable
distance, from the leased premises at no expense to Lessee.  The taking or
condemning of easements upon, in, over, and under the premises for the
installation, operation and maintenance of which will not adversely affect the
use of the buildings on the leased premises, shall likewise not be construed as
rendering the remaining portion of the leased premises unsuitable for the use of
the Lessee for the purpose for which the said premises were being used at the
time of the taking or condemnation and there shall be no reduction in rent
because of said taking.  The taking or condemnation of easements upon or over
the premises for aviation purposes, which do not affect the use of the buildings
on the leased premise shall not be construed as rendering the remaining portion
of the leased premises unavailable for the use by the Lessee for the purpose for
which the said premises were being used at the time of the taking or
condemnation and there shall be no reduction in rent because of said taking.

   If this lease shall terminate as provided in this Article, Lessor shall
refund to Lessee all sums received by Lessor as rent or deposit under this lease
in excess of rent due through the date of such termination, which rent due for
any part of a month to be determined by prorating rent due for a full month on a
daily basis. Such termination, however, shall be without prejudice to the rights
of either Lessor or Lessee to recover compensation and damage caused by
condemnation from the condemnor. It is further understood and agreed that
neither the Lessee nor Lessor shall have any rights in any award made to the
other by any condemnation authority.

                             BANKRUPTCY OF LESSEE
                             --------------------

   In the event a voluntary or involuntary petition in bankruptcy is filed
against Lessee and said petition is approved in the court in which filed, or a
receiver is appointed upon adverse petition and the appointment of such receiver
is not vacated within thirty (30) days, or in the event Lessee makes an
assignment for the benefit of creditors, Lessor reserves the right to terminate
this lease forthwith and without notice if rental payments are not current.

The MDT Corporation Employee Benefits Committee
 and Participants in the MDT Corporation Savings
 and Thrift Plan for Hourly Employees:


We have audited the accompanying statements of net assets available for plan
benefits of the MDT Corporation Savings and Thrift Plan for Hourly Employees as
of December 31, 1994 and 1993, and the related statements of changes in net
assets available for plan benefits for the years then ended.  These financial
statements are the responsibility of the Plan'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 net assets available for plan benefits of the MDT
Corporation Savings and Thrift Plan for Hourly Employees at December 31, 1994
and 1993, and the changes in those net assets available for plan benefits for
the years then ended, in conformity with generally accepted accounting
principles.

Our audits were made for the purpose of expressing an opinion on the basic
financial statements taken as a whole.  The supplemental schedules of assets
held for investment purposes and reportable transactions are presented for the
purpose of additional analysis and are not a required part of the basic
financial statements but are supplementary information required by the
Department of Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974.  The fund information in
the statements of net assets available for plan benefits and the statements of
changes in net assets available for plan benefits is presented for purposes of
additional analysis rather than to present the net assets available for plan
benefits and changes in net assets available for plan benefits of each fund.
The supplemental schedules and fund information have been subjected to the
auditing procedures applied in the audits of the basic financial statements and,
in our opinion, are fairly stated in all material respects in relation to the
basic financial statements taken as a whole.

                    MDT CORPORATION SAVINGS AND THRIFT PLAN
                              FOR HOURLY EMPLOYEES

                         Notes to Financial Statements

                               December 31, 1994


(1)  Description of the Plan
     -----------------------

     The following description of the MDT Corporation Savings and Thrift Plan
     for Hourly Employees (the Plan) provides only general information.
     Participants should refer to the Plan document for a more complete
     description of the Plan's provisions.

     The Plan is a defined contribution plan covering substantially all MDT
     Corporation (Corporation) hourly employees who are not covered under a
     collective bargaining agreement. Hourly employees of the Corporation who
     are not covered under a collective bargaining agreement may elect to
     participate in the Plan commencing the first calendar quarter following
     completion of one hour of service.

     The Plan provides that participants may elect to make a basic contribution
     of up to 6% of their total annual compensation. The Corporation makes a
     matching contribution equal to 30% of the first 2%, 40% of the next 2%, and
     50% of the final 2% of a participant's basic contribution. In addition,
     participants who contribute the maximum basic contribution may make a
     supplemental contribution in tax-deferred dollars, taxed dollars, or a
     combination which, when added to the basic contribution, cannot exceed 18%,
     16%, and 25%, respectively, of their total annual compensation. The
     supplemental contribution is not matched by the Corporation.

     Separate employee and Corporation contribution accounts are maintained for
     each participant. Participants have a 100% nonforfeitable vested interest
     in their basic and supplemental contributions at all times. Employees vest
     in the Corporation contributions at a rate of 20% after one year of service
     and an additional 20% each year thereafter until five years of service are
     completed. Forfeitures arising under the Plan are used to reduce the
     Corporation's contribution to the Plan.

     Distributions made upon termination, death, or permanent disability may at
     the employee's election be in the form of a lump sum or in installments
     over a period not to exceed ten years.


(2)  Summary of Significant Accounting Policies
     ------------------------------------------

     The following are the significant accounting policies followed by the Plan:

     Basis of Presentation
     ---------------------

     The accompanying financial statements have been prepared on an accrual
     basis and present the net assets available for plan benefits and changes in
     those net assets.

                                                                     (Continued)

(2)  Summary of Significant Accounting Policies (continued)
     ------------------------------------------            

     Investments
     -----------

     The Plan's interest in the Master Trust is valued based on the fair value
     of the underlying assets of the Master Trust. The employer identification
     number under which the Master Trust has been filed is 161326160.

     The accounting policies of the Master Trust operated under the MDT
     Corporation Savings and Thrift Master Trust Agreement (Master Trust) are as
     follows:

     Marketable securities are valued at the last reported sales price on the
     last business day of the year. Quotations are obtained from national
     securities exchanges or, in instances where securities are not listed on
     any of the exchanges, quotations are obtained from brokerage firms.

     The Open End Guaranteed Income Fund II invests in benefit responsive fixed
     and variable payment guaranteed investment contracts (GICs) and bank
     investment contracts (BICs). The GIC and BIC investments are carried at
     contract value which approximates fair value.

     Purchases and sales of securities are recorded on the trade date. Dividend
     income is recorded on the ex-dividend date. Interest is recognized on the
     accrual basis.


(3)  Plan Amendments
     ---------------

     In 1994, the Plan was amended to include a loan fund for participants.
     Participants are permitted to borrow from their savings accounts subject to
     certain limitations. The loans are payable over terms up to nine years and
     bear interest at the commercial prime rate in effect at the time the loan
     is made plus 1%. Principal and interest payments on the loans are
     redeposited into the participants' accounts based on their current
     investment allocation elections. At December 31, 1994, market value of
     loans approximates fair value.


(4)  Investments
     -----------

     Participants may elect to invest their contributions in the Open End
     Guaranteed Income Fund II, the Equity Index Fund II, the MDT Corporation
     Stock Fund, the U.S. Government Fund (formerly the Intermediate and Long
     Term Bond Fund II), and the Asset Management Fund II

                                      -2-                            (Continued)

     in multiples of 10%. Income from investments is allocated to a
     participant's account monthly in the proportion that the individual account
     bears to the total of all accounts.

     The investments of the Plan are held by Bankers Trust as trustee under the
     Master Trust. Plans participating in the Master Trust are the Plan, the MDT
     Corporation Savings and Thrift Plan for Salaried Employees (Salaried Plan)
     and the MDT Corporation Savings and Thrift Plan for Union Employees (Union
     Plan).

     Except for the loan fund, which is participant specific, investments and
     certain related accounts in the statements of net assets available for plan
     benefits at December 31, 1994 and 1993 and statements of changes in net
     assets available for plan benefits for the years then ended represent
     allocations of the assets of the Master Trust based upon proportionate
     interest of the Plan in individual Master Trust investment funds.

     The following information is presented for the Master Trust and each of the
     Master Trust investment accounts:

(5)  Federal Income Taxes
     --------------------

     Participants are not taxed currently on employer contributions to the Plan
     or on income earned by the Plan. Distributions of benefits to employees,
     unless appropriately transferred to another qualified plan, generally are
     subject to federal income tax.

     The Internal Revenue Service issued its latest determination letter on
     August 24, 1993 which stated that the Plan and the related trust are
     designed in accordance with applicable sections of the Internal Revenue
     Code (IRC). The Plan has been amended since receiving the determination
     letter; however, the Plan administrator believes that the Plan is designed
     and is currently being operated in compliance with the applicable
     requirements of the IRC.


(6)  Plan Termination
     ----------------

     Although it has not expressed any intent to do so, MDT Corporation has the
     right under Article II of the Savings and Thrift Plan for Hourly Employees
     to discontinue its contributions at any time and to terminate the Plan
     subject to the provisions of ERISA. In the event of plan termination,
     participants will become 100% vested in their accounts.

The MDT Corporation Employee Benefits Committee
 and Participants in the MDT Corporation Savings
 and Thrift Plan for Salaried Employees:


We have audited the accompanying statements of net assets available for plan
benefits of the MDT Corporation Savings and Thrift Plan for Salaried Employees
as of December 31, 1994 and 1993, and the related statements of changes in net
assets available for plan benefits for the years then ended.  These financial
statements are the responsibility of the Plan'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 net assets available for plan benefits of the MDT
Corporation Savings and Thrift Plan for Salaried Employees at December 31, 1994
and 1993, and the changes in those net assets available for plan benefits for
the years then ended, in conformity with generally accepted accounting
principles.

Our audits were made for the purpose of expressing an opinion on the basic
financial statements taken as a whole.  The supplemental schedules of assets
held for investment purposes and reportable transactions are presented for the
purpose of additional analysis and are not a required part of the basic
financial statements but are supplementary information required by the
Department of Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974.  The fund information in
the statements of net assets available for plan benefits and the statements of
changes in net assets available for plan benefits is presented for purposes of
additional analysis rather than to present the net assets available for plan
benefits and changes in net assets available for plan benefits of each fund.
The supplemental schedules and fund information have been subjected to the
auditing procedures applied in the audits of the basic financial statements and,
in our opinion, are fairly stated in all material respects in relation to the
basic financial statements taken as a whole.

                    MDT CORPORATION SAVINGS AND THRIFT PLAN
                             FOR SALARIED EMPLOYEES

                         Notes to Financial Statements

                               December 31, 1994


(1)  Description of the Plan
     -----------------------

     The following description of the MDT Corporation Savings and Thrift Plan
     for Salaried Employees (the Plan) provides only general information.
     Participants should refer to the Plan document for a more complete
     description of the Plan's provisions.

     The Plan is a defined contribution plan covering substantially all MDT
     Corporation (Corporation) salaried employees. Salaried employees of the
     Corporation may elect to participate in the Plan commencing the first
     calendar quarter following completion of one hour of service.

     The Plan provides that participants may elect to make a basic contribution
     of up to 6% of their total annual compensation. The Corporation makes a
     matching contribution equal to 30% of the first 2%, 40% of the next 2%, and
     50% of the final 2% of a participant's basic contribution. In addition,
     participants who contribute the maximum basic contribution may make a
     supplemental contribution in tax-deferred dollars, taxed dollars, or a
     combination which, when added to the basic contribution, cannot exceed 18%,
     16%, and 25%, respectively, of their total annual compensation. The
     supplemental contribution is not matched by the Corporation.

     Separate employee and Corporation contribution accounts are maintained for
     each participant. Participants have a 100% nonforfeitable vested interest
     in their basic and supplemental contributions at all times. Employees vest
     in the Corporation contributions at a rate of 20% after one year of service
     and an additional 20% each year thereafter until five years of service are
     completed. Forfeitures arising under the Plan are used to reduce the
     Corporation's contribution to the Plan.

     Distributions made upon termination, death, or permanent disability may at
     the employee's election be in the form of a lump sum or in installments
     over a period not to exceed ten years.


(2)  Summary of Significant Accounting Policies
     ------------------------------------------

     The following are the significant accounting policies followed by the Plan:

     Basis of Presentation
     ---------------------

     The accompanying financial statements have been prepared on an accrual
     basis and present the net assets available for plan benefits and changes in
     those net assets.

                                                                     (Continued)

                         Notes to Financial Statements



(2)  Summary of Significant Accounting Policies (continued)
     ------------------------------------------            

     Investments
     -----------

     The Plan's interest in the Master Trust is valued based on the fair value
     of the underlying assets of the Master Trust. The employer identification
     number under which the Master Trust has been filed is 161326160.

     The accounting policies of the Master Trust operated under the MDT
     Corporation Savings and Thrift Master Trust Agreement (Master Trust) are as
     follows:

     Marketable securities are valued at the last reported sales price on the
     last business day of the year. Quotations are obtained from national
     securities exchanges or, in instances where securities are not listed on
     any of the exchanges, quotations are obtained from brokerage firms.

     The Open End Guaranteed Income Fund II invests in benefit responsive fixed
     and variable payment guaranteed investment contracts (GICs) and bank
     investment contracts (BICs). The GIC and BIC investments are carried at
     contract value which approximates fair value.

     Purchases and sales of securities are recorded on the trade date. Dividend
     income is recorded on the ex-dividend date. Interest is recognized on the
     accrual basis.


(3)  Plan Amendments
     ---------------

     In 1994, the Plan was amended to include a loan fund for participants.
     Participants are permitted to borrow from their savings accounts subject to
     certain limitations. The loans are payable over terms up to nine years and
     bear interest at the commercial prime rate in effect at the time the loan
     is made plus 1%. Principal and interest payments on the loans are
     redeposited into the participants' accounts based on their current
     investment allocation elections. At December 31, 1994, market value of
     loans approximates fair value.


(4)  Investments
     -----------

     Participants may elect to invest their contributions in the Open End
     Guaranteed Income Fund II, the Equity Index Fund II, the MDT Corporation
     Stock Fund, the U.S. Government Fund (formerly the Intermediate and Long
     Term Bond Fund II), and the Asset Management Fund II

                                      -2-                            (Continued)

     in multiples of 10%. Income from investments is allocated to a
     participant's account monthly in the proportion that the individual account
     bears to the total of all accounts.

     The investments of the Plan are held by Bankers Trust as trustee under the
     Master Trust. Plans participating in the Master Trust are the Plan, the MDT
     Corporation Savings and Thrift Plan for Hourly Employees (Hourly Plan) and
     the MDT Corporation Savings and Thrift Plan for Union Employees (Union
     Plan).

     Except for the loan fund, which is participant specific, investments and
     certain related accounts in the statements of net assets available for plan
     benefits at December 31, 1994 and 1993 and statements of changes in net
     assets available for plan benefits for the years then ended represent
     allocations of the assets of the Master Trust based upon proportionate
     interest of the Plan in individual Master Trust investment funds.

     The following information is presented for the Master Trust and each of the
     Master Trust investment accounts:

                         Notes to Financial Statements



(5)  Federal Income Taxes
     --------------------

     Participants are not taxed currently on employer contributions to the Plan
     or on income earned by the Plan. Distributions of benefits to employees,
     unless appropriately transferred to another qualified plan, generally are
     subject to federal income tax.

     The Internal Revenue Service issued its latest determination letter on
     August 24, 1993 which stated that the Plan and the related trust are
     designed in accordance with applicable sections of the Internal Revenue
     Code (IRC). The Plan has been amended since receiving the determination
     letter; however, the Plan administrator believes that the Plan is designed
     and is currently being operated in compliance with the applicable
     requirements of the IRC.


(6)  Plan Termination
     ----------------

     Although it has not expressed any intent to do so, MDT Corporation has the
     right under Article II of the Savings and Thrift Plan for Salaried
     Employees to discontinue its contributions at any time and to terminate the
     Plan subject to the provisions of ERISA. In the event of plan termination,
     participants will become 100% vested in their accounts.

The MDT Corporation Employee Benefits Committee
 and Participants in the MDT Corporation Savings
 and Thrift Plan for Union Employees:


We have audited the accompanying statements of net assets available for plan
benefits of the MDT Corporation Savings and Thrift Plan for Union Employees as
of December 31, 1994 and 1993, and the related statements of changes in net
assets available for plan benefits for the years then ended. These financial
statements are the responsibility of the Plan'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 net assets available for plan benefits of the MDT
Corporation Savings and Thrift Plan for Union Employees at December 31, 1994 and
1993, and the changes in those net assets available for plan benefits for the
years then ended, in conformity with generally accepted accounting principles.

Our audits were made for the purpose of expressing an opinion on the basic
financial statements taken as a whole.  The supplemental schedules of assets
held for investment purposes and reportable transactions are presented for the
purpose of additional analysis and are not a required part of the basic
financial statements but are supplementary information required by the
Department of Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974.  The fund information in
the statements of net assets available for plan benefits and the statements of
changes in net assets available for plan benefits is presented for purposes of
additional analysis rather than to present the net assets available for plan
benefits and changes in net assets available for plan benefits of each fund.
The supplemental schedules and fund information have been subjected to the
auditing procedures applied in the audits of the basic financial statements and,
in our opinion, are fairly stated in all material respects in relation to the
basic financial statements taken as a whole.

                    MDT CORPORATION SAVINGS AND THRIFT PLAN
                              FOR UNION EMPLOYEES

                         Notes to Financial Statements

                               December 31, 1994


(1)  Description of the Plan
     -----------------------

     The following description of the MDT Corporation Savings and Thrift Plan
     for Union Employees (the Plan) provides only general information.
     Participants should refer to the Plan document for a more complete
     description of the Plan's provisions.

     The Plan is a defined contribution plan covering substantially all MDT
     Corporation (Corporation) union employees. Union employees of the
     Corporation may elect to participate in the Plan commencing the first
     calendar quarter following completion of one hour of service.

     The Plan provides that participants may elect to make a basic contribution
     of up to 6% of their total annual compensation. The Corporation makes a
     matching contribution equal to 30% of the first 2%, 40% of the next 2%, and
     50% of the final 2% of a participant's basic contribution. In addition,
     participants who contribute the maximum basic contribution may make a
     supplemental contribution in tax-deferred dollars, taxed dollars, or a
     combination which, when added to the basic contribution, cannot exceed 18%,
     16%, and 25%, respectively, of their total annual compensation. The
     supplemental contribution is not matched by the Corporation.

     Separate employee and Corporation contribution accounts are maintained for
     each participant. Participants have a 100% nonforfeitable vested interest
     in their basic and supplemental contributions at all times. Employees vest
     in the Corporation contributions at a rate of 20% after one year of service
     and an additional 20% each year thereafter until five years of service are
     completed. Forfeitures arising under the Plan are used to reduce the
     Corporation's contribution to the Plan.

     Distributions made upon termination, death, or permanent disability may at
     the employee's election be in the form of a lump sum or in installments
     over a period not to exceed ten years.


(2)  Summary of Significant Accounting Policies
     ------------------------------------------

     The following are the significant accounting policies followed by the Plan:

     Basis of Presentation
     ---------------------

     The accompanying financial statements have been prepared on an accrual
     basis and present the net assets available for plan benefits and changes in
     those net assets.
                                                                     (Continued)

(2)  Summary of Significant Accounting Policies (continued)
     ------------------------------------------            

     Investments
     -----------

     The Plan's interest in the Master Trust is valued based on the fair value
     of the underlying assets of the Master Trust. The employer identification
     number under which the Master Trust has been filed is 161326160.

     The accounting policies of the Master Trust operated under the MDT
     Corporation Savings and Thrift Master Trust Agreement (Master Trust) are as
     follows:

     Marketable securities are valued at the last reported sales price on the
     last business day of the year. Quotations are obtained from national
     securities exchanges or, in instances where securities are not listed on
     any of the exchanges, quotations are obtained from brokerage firms.

     The Open End Guaranteed Income Fund II invests in benefit responsive fixed
     and variable payment guaranteed investment contracts (GICs) and bank
     investment contracts (BICs). The GIC and BIC investments are carried at
     contract value which approximates fair value.

     Purchases and sales of securities are recorded on the trade date. Dividend
     income is recorded on the ex-dividend date. Interest is recognized on the
     accrual basis.


(3)  Plan Amendments
     ---------------

     In 1994, the Plan was amended to include a loan fund for participants.
     Participants are permitted to borrow from their savings accounts subject to
     certain limitations. The loans are payable over terms up to nine years and
     bear interest at the commercial prime rate in effect at the time the loan
     is made plus 1%. Principal and interest payments on the loans are
     redeposited into the participants' accounts based on their current
     investment allocation elections. At December 31, 1994, market value of
     loans approximates fair value.


(4)  Investments
     -----------

     Participants may elect to invest their contributions in the Open End
     Guaranteed Income Fund II, the Equity Index Fund II, the MDT Corporation
     Stock Fund, the U.S. Government Fund (formerly the Intermediate and Long
     Term Bond Fund II), and the Asset Management Fund II
                                                                     (Continued)

     in multiples of 10%. Income from investments is allocated to a
     participant's account monthly in the proportion that the individual account
     bears to the total of all accounts.

     The investments of the Plan are held by Bankers Trust as trustee under the
     Master Trust. Plans participating in the Master Trust are the Plan, the MDT
     Corporation Savings and Thrift Plan for Hourly Employees (Hourly Plan) and
     the MDT Corporation Savings and Thrift Plan for Salaried Employees
     (Salaried Plan).

     Except for the loan fund, which is participant specific, investments and
     certain related accounts in the statements of net assets available for plan
     benefits at December 31, 1994 and 1993 and statements of changes in net
     assets available for plan benefits for the years then ended represent
     allocations of the assets of the Master Trust based upon proportionate
     interest of the Plan in individual Master Trust investment funds.

     The following information is presented for the Master Trust and each of the
     Master Trust investment accounts:

                                                                     (Continued)

(5)  Federal Income Taxes
     --------------------

     Participants are not taxed currently on employer contributions to the Plan
     or on income earned by the Plan. Distributions of benefits to employees,
     unless appropriately transferred to another qualified plan, generally are
     subject to federal income tax.

     The Internal Revenue Service issued its latest determination letter on
     August 24, 1993 which stated that the Plan and the related trust are
     designed in accordance with applicable sections of the Internal Revenue
     Code (IRC). The Plan has been amended since receiving the determination
     letter; however, the Plan administrator believes that the Plan is designed
     and is currently being operated in compliance with the applicable
     requirements of the IRC.


(6)  Plan Termination
     ----------------

     Although it has not expressed any intent to do so, MDT Corporation has the
     right under Article II of the Savings and Thrift Plan for Union Employees
     to discontinue its contributions at any time and to terminate the Plan
     subject to the provisions of ERISA. In the event of plan termination,
     participants will become 100% vested in their accounts.
