                                    PART I
      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, MDT Diagnostic Company, which produces and sells
  Examining and Operatory Equipment, and 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
  Sterility Assurance Systems and Examining and Operatory Equipment. The Company
  also operates several 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 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 45% and 19% of its revenues
  from sales of Sterility Assurance Systems and Examining and Operatory
  Equipment, respectively, and approximately 36% 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 18.5% of the Company's revenues. Financial
  information can be found in Items 6, 7 and 8 of this Annual Report.

      MDT intends to maintain and, where and when possible, expand its
  healthcare products and service business through the internal development of
  new products and services complementary to its current activities. See
  "Business --Product Development." The Company anticipates that expansion may
  also take place, both domestically and internationally, through the
  development of new manufacturing, distribution, sales and other strategic
  relationships with third parties. See "Business -- Products" and "Business --
  Marketing."

      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; a perceived market need to
  switch from ethylene oxide sterilizers to newer technology plasma units; 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 (hospital-based, surgery center and
  medical offices) will approach 31 million in 1996. This is an increase of
  almost 41% from the 22 million performed in 1985. During this same period, the
  proportion of procedures performed in an outpatient setting has increased from
  just under 40% in 1985 to a predicted level of almost 70% in 1996. 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 hospital and
  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
  increasing industry efficiencies and strengthening 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 and services.

  Recent Company Events

      Getinge Transaction

      On May 12, 1996, the Company announced that it had entered into an
  Agreement and Plan of Merger (the "Merger Agreement") pursuant to which it is
  proposed to be acquired by Getinge Industrier AB, a Swedish manufacturer of
  hospital and scientific equipment. On May 17, 1996, Getinge commenced a tender
  offer for all outstanding shares of the Company's common stock for a cash
  price of $4.50 per share. On July 12, 1996, Getinge announced an extension of
  its tender offer until July 25, 1996 and an increase in the offer price to
  $5.50 per share. Consummation of the tender offer is subject to certain terms
  and conditions set forth in the Merger Agreement, including the approval of
  the holders of two-thirds of the shares to be acquired and certain regulatory
  approvals. If the tender offer is consummated, those shares not acquired in
  the tender offer will be converted into $5.50 in cash pursuant to a merger to
  be effected following completion of the tender offer.

                                       2

      Environmental Remediation

      In connection with Getinge's investigation of the Company, the conduct of
  environmental tests revealed previously undiscovered soil and groundwater
  contamination at the Company's manufacturing facilities in Henrietta, New York
  and North Charleston, South Carolina. The Company estimates that the cost of
  remediating such contamination will range from $1,350,000 to $2,700,000, and a
  reserve of $1,350,000 was established in the fourth quarter of fiscal year
  1996 to meet anticipated remediation obligations. See Item 2 -"Properties."

      Bank Matters

      The Company's operating results for the quarter and year ended March 31,
  1996 have caused the Company to be in default under certain financial
  covenants contained in its amended bank credit agreement with Wells Fargo
  Bank, National Association, and Chase Bank, National Association. The Company
  and the banks are negotiating a forbearance agreement pursuant to which the
  banks would agree to refrain for a limited time period from exercising their
  remedies under the amended bank credit agreement and related loan documents.
  If the Getinge transaction is consummated, Getinge has advised the Company
  that Getinge has obtained commitements from its lenders sufficient to retire
  the loans outstanding under the Company's amended bank credit agreement. If
  the Getinge transaction is not consummated, the Company has received a
  proposal and is pursuing a commitment from Congress Financial Corporation to
  refinance the Company's existing bank credit facility with a three-year,
  secured line of credit up to $37,500,000. No assurance can be given, however,
  that a forberance agreement or alternative financing will be obtained. See
  Item 7, "Management's Discussion and Analysis of Financial Condition and
  Results of Operations--Liquidity and Capital Resources."

      First Quarter Operating Results

      On July 10, 1996, the Company announced that bookings for the first 
  quarter ended June 30, 1996, were $28,844,000 compared to $32,844,000 in the 
  same quarter a year earlier, a decrease of 12.2%, reflecting ongoing weak 
  domestic demand for hospital capital equipment and a decline in service 
  bookings. The backlog of orders at June 30, 1996 was $24,649,000 compared to 
  $28,496,000 a year earlier, a decrease of 13.5%. Revenues were $28,035,000 
  during the first quarter, compared to $30,899,000 in the first quarter a year 
  earlier, representing a decrease of 9.3%. The Company expects to
  report a loss for the first quarter, before costs related to further
  organizational changes, the Getinge transaction and refinancings, of
  approximately $1,200,000, or $.18 a share. After such costs, the quarter is
  expected to result in a loss of approximately $1,800,000, or $.27 a share. 

      Should the pending transaction with Getinge not be consummated, the
  Company anticipates that it will consider selling or liquidating certain
  product lines and related assets and instituting further cost reduction
  measures. Significant charges may be incurred in connection with such
  actions, some of which might be recorded as of June 30, 1996. In that case,
  the loss experienced for the first quarter would be greater than that
  estimated above.
  
    Products

      The Company's products are organized into three product groups, Sterility
  Assurance Systems, Examining and Operatory Equipment, and parts, service and
  consumable products. The following table sets forth the sales attributable to
  each for the periods indicated:

      Sterility Assurance Systems. MDT is one of the 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 products are marketed under the Castle
  and

                                       3
<PAGE>
 
  Harvey 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 are available.
  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
  rapidly process while reducing the possibility of 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.

      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, McKesson and Wilson brand names. The major product lines
  are examination, treatment and surgical tables and lighting systems, dental x-
  ray machines and dental chairs, instrument delivery systems and stainless
  steel accessory products. In addition, the Company has an agreement with
  Kreuzer GmbH, located in Puchheim, Germany, under which the Company acts as an
  exclusive distributor of Kreuzer operating room systems in the United States
  and Canada. The Kreuzer systems, which deliver and control gases, oxygen and
  power for anesthesia, diagnostic and monitoring equipment, are complementary
  to and compatible with operating room tables, lights and related accessories
  presently manufactured and marketed by the Company. Such systems are also
  installed and serviced by MDT Technionic Company.

      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 both in the field and in two service centers within
  the United States 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.

                                       4
<PAGE>
 
      Should the pending Getinge transaction not be consummated, the Company has
  under consideration the disposition or discontinuance of certain product lines
  together with the consolidation of related channels of distribution. These
  measures are a continuation of the Company's efforts to improve profitability.
  The implementation of these measures could result in reserves being taken for
  inventory, severance and asset impairment, some of which might be recorded as 
  of June 30, 1996.

      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 carry 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 15 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.  With the exception of the hospital sales force in fiscal year
  1996, 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).  In
  fiscal year 1996, the Company, as part of its business unit reorganization,
  split the hospital sales force between MDT Biologic Company and MDT Diagnostic
  Company.  In fiscal 1997, the Company has re-combined the hospital sales force
  with the expectation of achieving broader coverage at lower cost.   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 (which range from one to three
  years in duration) with national and regional hospital accounts and group
  purchasing organizations.

      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.

      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 1996, 1995 or 1994, and no material part of the business is
  dependent upon a single customer or a few customers.

  Product Development

      MDT expended $4,519,000, $4,451,000 and $4,692,000 on product development
  in the fiscal years ended March 31, 1996, 1995 and 1994, respectively.  Since
  March 31, 1993, 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, systems 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 advanced versions of Shampaine surgical tables, 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.

      The Company's research and development program in the field of chemical
  sterilization of temperature, moisture and pressure sensitive instruments
  continued in fiscal 1996, as it will in fiscal

                                       6
<PAGE>
 
  1997.  The Company has acquired an option to purchase certain patents and
  related rights covering sterilization of 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 had initially expected to seek FDA approval and
  to market a product incorporating this technology during 1996.  However, this
  timetable has been delayed due in part to the Company's discovery during
  product testing of the incompatibility of certain materials proposed for use
  in the manufacture of the product.  The Company now expects to market a
  product based on these patents in 1997, although significant further
  investment as well as regulatory approval 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 may in the
  future seek appropriate opportunities to enter into manufacturing,
  distribution, sales and other strategic relationships with third parties, both
  domestically and internationally.

      The foregoing statements regarding the introduction and marketing of new
  products and product enhancements constitute forward-looking statements within
  the meaning of Section 21E of the Securities Exchange Act of 1934, as amended,
  and as such, are subject to certain risks and uncertainties.  The ability of
  the Company to develop and market new products and enhancements within the
  specified time periods depends upon a number of factors, including the
  investment of additional capital, successful completion of product testing in
  accordance with current protocols and the receipt of applicable regulatory
  approvals.

  Manufacturing

      MDT's production facilities utilize numerically controlled and robotic
  tools and contain sections for machining, metal fabricating, welding and
  brazing, painting and finishing, buffing, assembling, 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, 1996 and 1995, were approximately
  $23.8 million and $27.1 million, respectively, of which approximately $18.5
  million and $21.2 million, respectively, were for Sterility Assurance Systems
  and approximately $5.3 million and $5.9 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 1997, with the remainder to be
  filled in fiscal 1998.

  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 AMSCO International, Inc., a
  subsidiary of Steris Corporation; Getinge Industrier AB; and, in the tabletop
  sterilizer market, with several private companies. On May 12, 1996, the
  Company entered into an agreement pursuant to which it is proposed to be
  acquired by Getinge Industrier AB. See "Business -- Recent Company Events."
  Product features, reliability,

                                       7
<PAGE>
 
  operating costs, after-sales service, and price are the most prevalent
  competitive factors with respect to these products, with price becoming an
  increasingly important factor.

      The Company competes in Examining and Operatory Equipment primarily with
  AMSCO International, Inc., ALM, 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.

      The Company competes in the service business with AMSCO International,
  Inc., large bio-med groups such as Cohr, Inc. and National M.D., as well as
  large in-house hospital bio-med groups.  The size of the installed based of
  MDT equipment, price, and the desire to consolidate vendors are the most
  prevalent competitive factors.

  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, three of
  which were issued during the fiscal year ended March 31, 1996. 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, Unispore, Chemitest and Sani-Jet.
  Registered marks used in connection with Examining and Operatory Equipment
  include MDT, Castle, Shampaine, Radi-Op, McKesson, Steri-grip and Wilson.

  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
  advertising claims.  Some of the Company's sterilizers and sterilization
  products also may 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 toxicants 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 into the environment of substances which may be
  carcinogenic or reproductive toxicants.  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 into 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

                                       8
<PAGE>
 
  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").

      In February 1996, after internal quality control tests revealed that
  certain quantities of Vapo-Steril manufactured by the Company contained non-
  standard concentrations of that sterilant, the Company voluntarily commenced a
  recall of approximately 80,000 bottles of Vapo-Steril previously sold to
  dealers. The Company annually produces a total of approximately 930,000
  bottles of Vapo-Steril. The Company subsequently notified the FDA and the EPA
  of the defective Vapo-Steril and the voluntary recall. The FDA acknowledged
  the Company's notification and ordered the Company to proceed with its recall.
  To date, approximately 45% of the dealers notified of the recall have
  responded with their findings, encompassing about 65% of the bottles subject
  to the recall. The Company has provided replacement bottles at no charge to
  all customers returning or destroying the defective Vapo-Steril. If and when a
  sufficient number of dealers have responded to the recall, the Company intends
  to request that the FDA formally cancel its recall order.
  
      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 by 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 was banned effective January 1, 1996, 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
  modification kits with which its installed base of ethylene oxide sterilizers
  can be retrofitted for use with 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 for use in the
  prevention 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 known as "Good Manufacturing Practices" for
  manufacturers of medical devices. Each manufacturing facility of the Company
  must be registered annually and is subject to recurring 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 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 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 to
  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.

      During 1995, the United States District Court for the District of
  Massachusetts found that (i) the plasma sterilization testing and development
  work by MDT did not infringe the patent asserted by AbTox, (ii) the Exitron
  patents being asserted are not unenforceable due to inequitable conduct, and
  (iii) AbTox's plasma sterilizer does not infringe the Exitron patents asserted
  by MDT. MDT has appealed the court's finding that the AbTox plasma sterilizer
  does not infringe the Exitron patents, and AbTox has filed a cross-appeal with
  respect to the court's finding that the testing and development work performed
  by MDT did not infringe the patent asserted by AbTox. In addition, AbTox has
  filed motions with the court in Canada to seek findings that the Exitron
  patents are invalid and that its plasma sterilizer does not infringe on the
  Exitron patents. MDT intends vigorously to pursue its infringement claims and
  to oppose the AbTox claims.

  Employees

      At March 31, 1996, MDT employed 1,089 persons full-time in the following
  areas: manufacturing, engineering and quality assurance (538); marketing and
  sales (173); product support (270); administration (58); and research,
  development and compliance (50). 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 (which has, effective as of July 1, 1996, been renamed the
  Retirement Savings Plan for Hourly Employees) covering its nonunion hourly
  employees and the MDT Biologic Company Union Thrift Plan covering its union
  members. These plans are similar to the MDT Corporation Savings and Thrift
  Plan for Salaried Employees, except that the union plan does not provide
  retirement contributions similar to those previously set forth in the MDT
  Corporation Retirement Plan. Effective as of July 1, 1996, the MDT Corporation
  Retirement Plan was merged with two other Company employee benefit plans. See
  Item 7, "Executive Compensation -- Employee Benefit Plans -- Retirement Plan."

  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 several 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 Henrietta and Rancho Dominguez properties are part of
  the security for the Company's amended bank credit agreement having an
  aggregate outstanding principal balance of $33,300,000 as of March 31, 1996.
  The Company is currently in default under certain financial covenants
  contained in the amended bank credit agreement. See Item 7, "Management's
  Discussion and Analysis of Financial Condition and Results of Operations --
  Liquidity and Capital Resources" and Note 8 and Note 9 to Consolidated
  Financial Statements. The Company owns 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 $236,000 as of March
  31, 1996. See Note 9 of Notes to Consolidated Financial Statements.

      The Company occupies four leased facilities in North Charleston, South
  Carolina, under the terms of three coterminous leases. These facilities house
  the Company's third operating subsidiary, MDT Diagnostic Company, and a
  service center for MDT Technionic Company. The Company owns 15 acres of land
  in Summerville, South Carolina (adjacent to North Charleston), on which it
  intended to construct and occupy a new manufacturing and engineering facility.
  Due to the present business climate and financial results, the Company has
  listed the real property for sale.

      The Company occupies its corporate headquarters in Durham, North Carolina
  under the terms of a lease which expires August 11, 2001. The Company also
  leases a government sales office in Arnold, Maryland and sales and service
  offices in Athens, Greece and Hong Kong. Warehouse facilities as well as sales
  and service offices are leased in Mississauga, Ontario, and Montreal, Quebec,
  Canada. As part of its reorganization, the Company closed during fiscal 1996,
  extending to the first quarter of fiscal 1997, the Plano, Texas, warehouse
  facility and three domestic sales and service offices.

  (a) Consists of four leased facilities. The leases pertaining to three of the
      facilities (comprising approximately 121,000 square feet) expire in
      December 1996, but include up to four annual renewal options in favor of
      the Company. The lease pertaining to the fourth facility (comprising
      11,400 square feet) expires in December 1996.


      Under various federal, state and local laws, ordinances and regulations,
  an owner or operator of real estate is liable for the costs of removal or
  remediation of certain hazardous or toxic substances on or in such property.
  Such laws often impose such liability without regard to whether the owner knew
  of, or was responsible for, the presence of such hazardous or toxic
  substances. The costs of investigation, removal or remediation of such
  substances may be substantial, and the presence of such substances, or the
  failure to properly remediate such substances, may adversely affect the
  owner's ability to sell or rent such property or to borrow money using such
  property as collateral. Persons who arrange for the disposal or treatment of
  hazardous or toxic substances may also be liable for the costs of removal or
  remediation of a release of such substances at a disposal treatment facility,
  whether or not such facility is owned or operated by such person. In
  connection with the ownership, leasing or operation of real properties, and
  the conduct of manufacturing activities thereon, the Company may be considered
  an owner or operator of such properties or as having arranged for the disposal
  or treatment of hazardous or toxic substances and therefore, potentially
  liable for removal or remediation costs, as well as certain other related
  costs, including governmental fines and costs associated with injuries to
  persons and property.

      In connection with Getinge's investigation of the Company (see Item 1,
  "Business -- Recent Company Events"), the conduct of environmental tests
  revealed previously undiscovered soil and groundwater contamination by
  industrial solvents at the Company's manufacturing facility in Henrietta, New
  York and by industrial solvents and petroleum constituents at the Company's
  manufacturing facility in North Charleston, South Carolina. Some of the
  contaminants in the groundwater may have migrated to the facilities from an
  offsite source. The costs of remediating such contamination is currently
  estimated to range from $1,350,000 to $2,700,000, and a reserve of $1,350,000
  was established in the fourth quarter of fiscal year 1996 to meet anticipated
  remediation obligations. The ultimate cost, however, will depend on the
  extent of the contamination found as the remediation project progresses and
  the cleanup standards that the Company is required to meet.

  Item 3.  Legal Proceedings

      In addition to the legal proceedings described or referenced in this
  Annual Report under the caption "Business -- Product Liability and
  Litigation," the Company is a defendant in various other legal proceedings
  arising in the ordinary course of business. In the opinion of management, the
  outcome of such other legal proceedings will not have a material adverse
  impact on the consolidated financial position of the Company.

  were down 6.2% and sales of examining and operatory equipment by MDT
  Diagnostic were down 4.9% compared to the prior year.  Good overall
  performance in international markets was offset by lower domestic equipment
  sales resulting in part from continuing buyer uncertainty in domestic
  healthcare markets related to healthcare reform and industry consolidation and
  retrenchment.  Slightly higher sales by MDT Technionic reflect customer
  resolve to extend the utilization of existing equipment in the current
  environment.

      Incoming orders of $127,919,000 for the recent fiscal year were
  $6,615,000, or 4.9%, lower when compared to incoming orders of $134,534,000 in
  the prior fiscal year.  Stronger orders in the international and service
  markets were offset by weaker orders in the domestic healthcare markets.
  Backlog was $23,840,000 at March 31, 1996, compared to a backlog of
  $27,145,000 a year earlier.

      Gross profit of $36,739,000 was $6,159,000, or 14.4%, lower in fiscal 1996
  compared to fiscal 1995, while gross profit as a percentage of sales was 28.0%
  in the current fiscal year versus 31.7% in the prior fiscal year.  Current
  year gross profit and gross profit margin were reduced by fourth quarter
  adjustments which included inventory adjustments totaling $2,425,000,
  including a write-down of approximately $489,000 in connection with inventory
  purchased from a supplier who failed to maintain necessary compliance with FDA
  manufacturing standards; a write-off of approximately $1,082,000 relating to
  products whose sales are being discontinued by the Company; additional
  reserves for excess and obsolete inventory of approximately $855,000, relating
  primarily to the identification of slower-moving products and parts
  inventories; and higher LIFO reserves of approximately $133,000.  Gross
  margins were also decreased by $562,000 for increased warranty reserves of
  $260,000 and increased reserves for projected workers compensation expense of
  $302,000.  The decrease in gross profit and gross margin from the prior year
  (excluding the aforementioned) was also impacted by the additional combined
  effects of lower domestic sales, higher manufacturing costs resulting from
  reduced production levels, lower pricing and a relatively higher mix of
  international sales yielding generally lower margins.  These negative factors
  were partially offset by cost reductions implemented during the current and
  prior fiscal year.

      Operating expenses of $38,343,000 increased $988,000, or 2.6%, in fiscal
  1996 compared to fiscal 1995.  The increase in operating expenses reflects an
  increase of $424,000 for costs associated with patent litigation defense fees,
  approximately $179,000 to amortize assets relating to the Company's

                                       17
<PAGE>
 
  plasma sterilizer program and an increase of approximately $120,000 in
  expenditures to market to national accounts and group purchasing organizations
  combined with related higher administrative fees.  Overall, operating expenses
  as a percentage of sales increased to 29.2% in fiscal 1996 from 27.6% in
  fiscal 1995.

      Reorganization costs, reflecting employee severance payments and
  relocation costs related to the reorganization of the Company into three
  business units (including the relocation of the corporate office from
  Torrance, California, to Durham, North Carolina), totaling $2,035,000 were
  recorded in fiscal 1996. These costs are associated with the Company's efforts
  to lower its break-even point in the face of lower sales while at the same
  time improve the effectiveness of its operations, organization and structure.
  At March 31, 1996, the balance of reorganization costs accrued but not yet
  paid was $830,000. Further measures to reduce costs are being implemented by
  the Company. A reserve of approximately $315,000 to reflect costs incurred to
  effect such reductions, principally severance costs, is expected to be
  recorded in the first quarter of fiscal 1997. Further, the Company has under
  consideration the sale or discontinuance of certain product lines and related
  assets and the contraction or closure of certain distribution channels, which
  could result in further reserves and cost for inventory, severance and asset
  impairments. See Item 1 -- "Business -- Recent Company Events -- First Quarter
  Operating Results."

      The operating loss of $3,639,000 in fiscal 1996 was $7,947,000, or 184.5%,
  below the operating income of $4,308,000 in fiscal 1995, reflecting lower
  gross profit, higher operating expenses and higher reorganization costs.

      Interest expense decreased $71,000 in fiscal 1996 to $3,443,000.  The
  decrease was due primarily to lower average borrowings.

      Other expenses increased $1,596,000 to $1,709,000.  The increase includes
  a reserve for environmental remediation costs of $1,350,000 related to soil
  and ground water contamination at two of the Company's manufacturing
  facilities, approximately $410,000 for costs incurred in connection with the
  Getinge transaction and costs incurred in connection with the negotiation and
  amendment of the Company's bank credit agreement and a write-off of land
  improvement cost of $349,000 related to abandoned plans to construct a new
  manufacturing facility in South Carolina.  These costs were offset by a pre-
  tax gain of $518,000 from the sale of the Bovie product line of
  electrosurgical products.

      Income tax (benefit) is based upon an estimated rate of 31% for fiscal
  year 1996.  The tax rate used for the prior fiscal year was 59%.

      Net loss of $6,066,000, or $.90 per share, for fiscal 1996 compares to a
  net income of $276,000, or $.04 per share, for the same period in 1995,
  reflecting the above noted factors.

  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 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% 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 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 fiscal 1995 versus 32.1% in the prior year.  Fiscal 1995 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

                                       18
<PAGE>
 
  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, 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 fiscal 1995, the favorable gross profit
  impact of which was first realized during the fourth quarter of fiscal 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 year
  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 were associated with the Company's
  efforts to lower its break-even point in the face of market uncertainties
  while at the same time improve the effectiveness of its operations,
  organization and structure.  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 Durham, North Carolina,
  $287,000.

      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.

      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 was 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
  reflects primarily 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 year 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.

  Liquidity and Capital Resources

      During fiscal 1996, net cash provided by operating activities of $419,000
  was combined with proceeds from the sale of the Bovie product line of
  $2,631,000 to finance capital expenditures of $2,292,000 and net payments on
  borrowings of $730,000.

      At March 31, 1996, the Company's current ratio was 1.2 to 1 and working
  capital was $13,466,000. This compares to a current ratio of 1.5 to 1 and
  working capital of $23,427,000 at March 31, 1995. The decrease in working
  capital reflects the reclassification of bank term debt from long-term to
  current based on the Company's default under certain financial covenants
  contained in its amended bank credit agreement with Well Fargo Bank, National
  Association and Chase Bank, National Association, discussed below; adjustments
  to reduce the values of inventories; and increases in accrued liabilities
  discussed above in Results of Operations. At March 31, 1996, Stockholders'
  Equity per share was $5.82 compared to $6.72 at March 31, 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 relating to the Bovie line of electrosurgical products,
  which resulted in a pre-tax gain of $518,000.

      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.  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 $911,000 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 1996, MDT spent $893,000 on legal and professional
  fees related to this matter.  MDT expects to expend further amounts in fiscal
  1997 to commercialize the technology and to protect its patent position.

      Reorganization costs, reflecting employee severance payments and
  relocation costs related to the reorganization of the Company into three
  business units (including the relocation of the corporate office from
  Torrance, California, to Durham, North Carolina), totaling $2,035,000 were
  recorded in fiscal 1996.  These costs are associated with the Company's
  efforts to lower its break-even point in the face of lower sales while at the
  same time improve the effectiveness of its operations, organization and
  structure.  At March 31, 1996, the balance of reorganization costs accrued but
  not yet paid was $830,000.  Further measures to reduce costs are being
  implemented by the Company.  A reserve of approximately $315,000 to reflect
  costs incurred to effect such reductions, principally severance costs, is
  expected to be recorded in the first quarter of fiscal 1997.  Further, the
  Company has under consideration the sale or discontinuance of certain product
  lines and related assets and the contraction or closure of certain
  distribution channels, which could result in reserves for inventory and costs
  for severance and asset impairment.

      The Company made capital expenditures of $2,292,000 in fiscal 1996
  compared to $3,067,000 in fiscal 1995.  Capital expenditures are anticipated
  to total approximately $2,000,000 in fiscal 1997, for production machinery and
  equipment, tooling and molds.  Total committed capital expenditures were
  approximately $568,000 as of March 31, 1996.  The Company owns 15 acres of
  land in Summerville, South Carolina (adjacent to North Charleston), on which
  it intended to construct and occupy a new manufacturing and engineering
  facility.  Due to the present business climate and financial results, the
  Company has listed the real property for sale.

                                       20

      On May 12, 1996, the Company announced that it had entered into an
  Agreement and Plan of Merger (the "Merger Agreement") pursuant to which it is
  proposed to be acquired by Getinge Industrier AB, a Swedish manufacturer of
  hospital and scientific equipment . On May 17, 1996, Getinge commenced a
  tender offer for all outstanding shares of the Company's common stock for a
  cash price of $4.50 per share. On July 12, 1996, Getinge announced an
  extension of its tender offer until 5:00 p.m. EDT on July 25, 1996 and an
  increase in the offer price to $5.50 per share. Consummation of the tender
  offer is subject to certain terms and conditions set forth in the Merger
  Agreement, including the approval of the holders of two-thirds of the shares
  to be acquired and certain regulatory approvals. If the tender offer is
  consummated, those shares not acquired in the tender offer will be converted
  into $5.50 per share in cash pursuant to a merger to be effected following
  completion of the tender offer.

      The Company's operating results for the quarter and year ended March 31,
  1996 have caused the Company to be in default under certain financial
  covenants contained in its amended bank credit agreement with Wells Fargo
  Bank, National Association, and Chase Bank, National Association. The Company
  and the banks are negotiating a forbearance agreement pursuant to which the
  banks would agree to refrain for a limited period of time from exercising
  their remedies with respect to the covenant defaults. If entered into beween
  the Company and the banks, the forbearance agreement would also provide that,
  effective May 12, 1996, the interest rate charged to the Company on all loans
  outstanding under the amended credit agreement would be increased from the
  prime rate plus 0.5% on the line of credit and the prime rate plus 0.75% on
                                                                ----
  the term loan to the prime rate plus 2% on both loans. No assurance can be 
                                  ----
  given, however, that a forbearance agreement will be obtained.


      In connection with the Getinge transaction, the Company is advised that
  Getinge has received a commitment from its lenders sufficient to retire the
  loans outstanding under the amended bank credit agreement, although Getinge
  may also attempt to reach mutually agreeable terms with the Company's existing
  bank lenders. If the Getinge transaction is not consummated, the Company has
  received a proposal from Congress Financial Corporation to refinance the
  Company's existing bank credit facility. The proposal, which has been approved
  by Congress Financial's credit committee, is subject to legal documentation
  and other requirements and is for a three-year, secured line of credit up to
  $37,500,000. Availability under the proposed line would be determined from
  time to time on the basis of various lending formulae tied to the Company's
  accounts receivable and inventories. Loans under the proposed line would bear
  interest at one percent (1%) per annum above the prime rate charged by
  CoreStates Bank, N.A., or, at the Company's option, 3.25% above the adjusted
  Eurodollar rate. Proceeds from the proposed facility would be used to repay
  the Company's existing loans with Wells Fargo Bank and Chase Bank. No
  assurance can be given, however, that alternative financing will be obtained.

      In connection with Getinge's investigation of the Company, environmental
  tests revealed previously undiscovered soil and groundwater contamination at
  two of the Company's manufacturing facilities. See Item 2 - "Properties." The
  costs of remediating such contamination are currently estimated to range from
  $1,350,000 to $2,700,000 extended over three to five years. A reserve of
  $1,350,000 was established to meet anticipated remediation obligations.

      The Company expects to receive income tax refunds of approximately
  $1,300,000 as recovery of fiscal year 1996 estimated payments and as a
  carryback of net operating losses to prior years.  Appropriate filings have or
  are in the process of being made.

      The Company finances its working capital and capital expenditure needs
  from cash provided by operating activities and borrowings under the Company's
  bank credit agreement. The line of credit portion of the bank credit agreement
  totalling $22,700,000 at June 30, 1996, matures and is to be repaid in full
  with all accrued interest on August 1, 1996. Further, as discussed above, the
  Company is in default under certain financial covenants contained in its bank
  credit agreement. At June 30, 1996, the total outstanding balance of the bank
  credit agreement was $32,700,000. Going forward, the Company intends to
  finance its working capital and capital expenditure needs from cash provided
  by operating activities and from financing provided by Getinge (should the
  merger be consummated) or from new financing the Company is seeking from
  Congress Financial Corporation to replace its existing bank credit facility.
  No assurance can be given that the merger with Getinge will be consummated or
  that alternative financing will be obtained.

      Healthcare reform, both in the public and private sectors, has resulted in
  customer uncertainty, lower sales and pricing pressures. Independent of
  healthcare reform proposals, healthcare consolidations, alliances and buying
  groups 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 have had a negative impact on
  the Company. However, management anticipates that ultimately certain other
  longer-term trends in the healthcare industry will contribute to recovery 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 increased 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, 1996 and 1995 and the related consolidated
statements of income (loss), stockholders' equity and cash flows for each of the
years in the three-year period ended March 31, 1996.  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, 1996 and 1995 and the results of their operations
and their cash flows for each of the years in the three-year period ended March
31, 1996, in conformity with generally accepted accounting principles.

The accompanying consolidated financial statements have been prepared assuming
that the Company will continue as a going concern. The Company incurred a net
loss of $6,066,000 in fiscal 1996 and therefore was not in compliance with
certain covenants contained in its bank credit agreement. Accordingly,
borrowings under the Company's credit facilities are reflected as current
liabilities in the accompanying consolidated balance sheet. As more fully
described in note 17, the Company has agreed to be acquired by Getinge
Industrier AB ("Getinge") pursuant to a tender offer of $5.50 per share which
expires on July 25, 1996, and which indicates that Getinge is considering the
repayment of such borrowings for which a funding commitment has been obtained,
subject to certain terms and conditions. Additionally, as more fully
described in note 9, the Company has received a proposal from a new lender for
the repayment in full of such borrowings and for supplemental financing for the
Company. There can be no assurance that either of these transactions will be
consummated. The status of the existing credit facilities and the need for
borrowing capacity during fiscal 1997 raise substantial doubt about the
Company's ability to continue as a going concern. These matters and management's
plans are discussed further in notes 9 and 17. The consolidated financial
statements do not include any adjustments that might result from the outcome of
this uncertainty.

                  Notes to Consolidated Financial Statements

                            March 31, 1996 and 1995

(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). The
      cost of substantially all of the Company's inventories is determined using
      the last-in, first-out (LIFO) method.

      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
      agreements, consulting and licensing agreements and goodwill, are being
      amortized using the straight-line method over the shorter of their legal
      or estimated useful lives. Periodically, the Company assesses the
      recoverability of intangible assets and adjusts those assets based on the
      estimated future financial benefits.

      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.

             Notes to Consolidated Financial Statements, Continued


      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.

      The allowance for doubtful accounts is determined through analysis of
      various factors including the age of receivables and past write-offs.
 
      Earnings per Share

      Earnings per share are based upon weighted average common and common
      equivalent shares outstanding, amounting to 6,769,000, 6,775,000, and
      6,781,000 shares for each of the three years ended March 31, 1996, 1995
      and 1994, 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.

      Fair Value of Financial Instruments

      Statement of Financial Accounting Standards No. 107, "Disclosures about
      the Fair Value of Financial Instruments" (Statement 107) requires the
      disclosure of fair value information about financial instruments, whether
      or not recognized on the balance sheet, for which it is practicable to
      estimate the value. In cases where quoted market prices are not readily
      available, fair values are based on quoted market prices of comparable
      instruments. The carrying amount of cash and equivalents, accounts
      receivable and payable, accrued expenses and deferred income approximates
      fair value because of the short maturity of those instruments. The
      carrying amount of the long-term debt is considered to be representative
      of the fair value as the interest rates are based on market rates.

             Notes to Consolidated Financial Statements, Continued


      Use of Estimates

      The preparation of financial statements in conformity with generally
      accepted accounting principles requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities and
      disclosure of contingent assets and liabilities at the date of the
      financial statements and the reported amounts of revenues and expenses
      during the reporting period. Actual results could differ from those
      estimates.

(2)   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 with related 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).

(3)   Reorganization Costs

      During fiscal 1996 and 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 1996 restructuring program involves the reduction of 53 employees and
      consolidations of offices (including the relocation of the Corporate
      office from Torrance, California to Durham, North Carolina) and the
      reorganization of the Company into three business units. The March 31,
      1996 consolidated statement of income (loss) includes $2,035,000 of pre-
      tax charges related to the aforementioned employee terminations, office
      closures and relocations of which $854,000 had been accrued during fiscal
      year 1996. At March 31, 1996, $830,000, relating to severance and lease
      termination costs, remained in accrued liabilities for the 1996 and 1995
      restructuring programs. During 1996, $264,000 related to employee
      severance and facility closures for the 1996 and 1995 restructuring
      programs were paid and charged to accrued liabilities.

      The 1995 restructuring program involved the reduction of 70 employees and
      consolidations of offices and facilities. The March 31, 1995 consolidated
      statement of income includes $1,235,000 of pre-tax charges related to the
      aforementioned employee terminations and facility closures. At March 31,
      1995, $240,000 of this amount, relating to severance and lease termination
      costs, remained in accrued liabilities.

(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.

             Notes to Consolidated Financial Statements, Continued


      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.

(5)   Inventories

      Prior year inventory amounts have been reclassified to conform with 1996
      year end reporting. Certain inventories are valued using the LIFO method
      and comprise approximately 97% of consolidated inventories. Incremental
      LIFO reserves of $1,052,000 were recorded in fiscal 1996. Inventories
      valued using the LIFO method would be $3,847,000 and $2,795,000 greater at
      March 31, 1996 and 1995, 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, 1996 and 1995,
      LIFO inventories for book purposes exceeded those for tax purposes by
      $8,055,000 and $8,170,000, respectively.

      Because of the rapidly changing health care market, some portions of the
      Company's inventory of certain products may exceed near term demand.
      Management is continuing to refine the Company's methodology for assessing
      these circumstances. No estimate can be made of a range of amounts of loss
      that are reasonably possible should supply exceed near term demand for
      certain products.

(8)   Notes Payable

      The Company has a secured line of credit as part of a credit agreement
      with two commercial banks. The secured line of credit provides for
      advances up to 80% of eligible accounts receivable and 35% of eligible
      inventory not to exceed $25,800,000 at .5% above the banks' prime rate of
      interest (aggregate of 8.75% at March 31, 1996). In addition, the Company
      pays a quarterly commitment fee of .25% per annum on the average unused
      amount. The Company is not in compliance with certain financial covenants
      contained in the credit agreement (see note 9). The line is to be repaid
      in full, with all accrued interest, on August 1, 1996 unless renewed or
      extended. The line is secured by inventories, accounts receivable,
      equipment and intangible assets.

     Secured term-loan payable to two commercial banks in monthly principal
       installments of $200,000, due August 1, 2000, at the bank's prime rate
       plus 3/4% (9% at March 31, 1996). A separate interest agreement covering
       $4,833,000 capped the rate at 8.9% with a floor rate of 6%. The interest
       rate agreement was entered into at no cost to the Company and expires
       August 1, 1998.                                                                    $  10,600,000      $   6,833,000

      The secured term-loan and credit line (note 8) agreements contain certain
      restrictions on purchases of fixed assets and payment of dividends and
      various covenants regarding financial ratios. The Company is not in
      compliance with certain financial covenants contained in the credit
      agreement. The Company is negotiating a forbearance agreement with the
      banks related to this non-compliance that would be in effect until the
      proposed transaction with Getinge Industrier AB ("Getinge") is closed (see
      note 17). The Company is advised that

      Getinge has received a commitment from its lenders sufficient to retire
      the loans outstanding under the credit agreement, although Getinge may
      also attempt to reach mutually agreeable terms with the Company's existing
      bank lenders. Should the proposed transaction not be concluded, the
      Company would seek to negotiate a new credit agreement with Congress
      Financial Corporation from whom the Company has received a proposal to
      refinance the Company's existing bank credit agreement. The term-loan
      agreement is secured by inventories, accounts receivable, equipment and
      intangible assets.

      Given the debt covenant violations related to the secured term-loan
      payable and the fact that a waiver for the next fiscal year has not been
      obtained, the $10,600,000 due under this loan has been classified as due
      in fiscal 1997. Based on this classification, the aggregate maturities of
      long-term debt for fiscal years subsequent to March 31, 1996 are as
      follows:

(10)  Commitments and Contingent Liabilities
 
      Litigation
 
      The Company is involved in certain claims and legal actions arising in the
      ordinary course of business. In the opinion of management, based upon the
      advice of counsel, the ultimate disposition of these matters will not have
      a material adverse effect on the financial position or results of
      operations of the Company.

      Operating Leases

      The Company occupies manufacturing, warehousing and office facilities
      under terms of operating leases which expire at various dates through July
      2001. The annual minimum lease payments thereunder for the years
      subsequent to March 31, 1996 are as follows: 1997, $572,000; 1998,
      $155,000; 1999, $140,000; 2000, $117,000; 2001, $106,000 and thereafter,
      $51,000. Lease expense totaled $1,106,000, $1,076,000, and $942,000 for
      each of the three years ended March 31, 1996, 1995 and 1994, 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 $117,000, $144,000, and
      $185,000 in 1996, 1995 and 1994, respectively.

             Notes to Consolidated Financial Statements, Continued


     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
      policy 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.

      Environmental Liability

      The Company is subject to laws and regulations relating to the protection
      of the environment. Accruals for environmental matters are recorded when
      it is probable that a liability has been incurred and the amount of the
      liability can be reasonably estimated.

      During 1996, in connection with the proposed acquisition by Getinge (see
      note 17), Getinge engaged environmental consultants. The conduct of
      environmental tests revealed previously undiscovered soil and ground water
      contamination at two of the Company's facilities. Based on cost estimates
      provided by the consultants, the Company believes remediation costs will
      range from $1,350,000 to $2,700,000 and at March 31, 1996, the Company
      accrued $1,350,000. The ultimate cost, however, will depend on the extent
      of contamination found as the remediation project progresses. The Company
      expects remediation to be substantially complete within five years.

(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.
 
      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, 1996, 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, 1996, options for 768,266 shares were outstanding, of which

      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.

     A valuation allowance was deemed unnecessary at March 31, 1996, 1995 and
1994. It is more likely than not that the results of future operations will
generate sufficient taxable income to realize the deferred tax assets.

      The Company provides a defined benefit pension plan covering certain
      employees. The plan provides benefits of stated amounts for each year of
      service. The Company's funding policy for the plan is to make at least the
      minimum annual contributions required by applicable law.

      The components of the net periodic pension cost for each of the years 
      ended March 31, 1996, 1995 and 1994 are as follows:

      The weighted average discount rate used in determining the projected
      benefit obligation was 7.85% and 8.5% in 1996 and 1995, respectively.
 
      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 $967,000,
      $1,049,000, and $1,069,000 for the years ended March 31, 1996, 1995 and
      1994, 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 $732,000, $708,000, and
      $704,000 for the years ended March 31, 1996, 1995 and 1994, respectively.
 
      Supplemental Executive Retirement Plan

      The Company has a Supplemental Executive Retirement Plan (SERP) for
      officers of the Company. 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 $129,000, $106,000, and
      $87,000 for the years ended March 31, 1996, 1995 and 1994, 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.

</TABLE>

      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 1996; 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, 1996 by $47,000 and the aggregate net periodic
      postretirement benefit cost for the year ended March 31, 1996 would remain
      approximately equal. The weighted average discount rate used in
      determining the accumulated postretirement benefit obligation was 7.85%,
      8.5% and 8.0% in 1996, 1995 and 1994, respectively.

(17)  Pending Acquisition

      On May 12, 1996, MDT agreed to be acquired by Getinge Industrier AB
      ("Getinge"), a Swedish manufacturer of hospital and scientific equipment.
      A definitive merger agreement was signed pursuant to which Getinge will
      acquire all outstanding shares of MDT common stock by commencing a tender
      offer for such shares at a cash price of $4.50 per share. If certain
      conditions are met those shares not acquired in the tender offer will be
      converted into $4.50 in cash pursuant to a merger to be effected following
      completion of the tender offer. Consummation of the tender offer and the
      merger is subject to certain terms and conditions, including approval of
      the holders of two-thirds of the shares to be acquired and regulatory
      approvals.

      The tender offer was initially scheduled to expire on June 28, 1996, but
      has since been extended by Getinge until 5 p.m. EDT on July 12, 1996. On
      July 12, 1996, Getinge announced the extension of its tender offer at a
      price of $5.50 per share, a $1.00 increase over the previous tender offer
      price of $4.50 per share. The tender offer will now expire at 5 p.m. EDT
      on July 25, 1996. Other terms and conditions of the original tender offer
      remain intact, except that, if certain conditions are met those shares not
      acquired in the tender offer will be converted into $5.50 in cash 
      pursuant to a merger to be effected following completion of the tender 
      offer.

(A)  Amounts shown reflect cash and non-cash compensation earned by the Named
     Executive Officers.

(B)  Amounts shown represent expenses paid or reimbursed by the Company in
     connection with the relocation of the Named Executive Officer to Durham,
     North Carolina (in the case of Messrs. Branagan and Hein), Henrietta, New

     $6,114--Company payment to Retirement Plan; $10,440--Company payment to
     SERP; $428--Imputed Value-Life Insurance. Effective as of July 1, 1996, the
     Retirement Plan was merged with two other Company employee benefit plans,
     with the assets and administration of the Retirement Plan with respect to
     salaried employees transferred to the Retirement Savings Plan for Salaried
     Employees and that plan re-named the Retirement Savings Plan for Salaried
     Employees. See "Employee Benefits -- Retirement Plan".

(E)  Mr. Kinsey joined the Company in January, 1995 and became an executive
     officer effective April 1, 1995.

(F)  Mr. White joined the Company in January, 1995 and became an executive
     officer effective April 1, 1995. The amount of bonus compensation shown Mr.
     White during the 1996 fiscal year represents a signing bonus of $20,000 and
     a guaranteed bonus of $19,800 under the Company's Management Incentive
     Compensation Plan ("MICP"). The Board of Directors of the Company
     terminated the MICP effective April 1, 1996.


  Employment Agreements

      The Company has entered into separate employment agreements with Messrs.
  Branagan, Hein and White which respectively provide for annual salaries of not
  less than $270,599, $140,160 and $132,000 for such individuals or, in each
  case, such larger amount as the Board of Directors in its discretion
  determines. In addition, MDT Biologic has entered into an employment agreement
  with Mr. Nerby, MDT Diagnostic Company has entered into an employment
  agreement with Mr. Swenson, and MDT Technionic Company has entered into an
  employment agreement with Mr. Kinsey, which agreements respectively provide
  for annual salaries of not less than $144,000, $144,000 and $132,500 for such
  individuals or, in each case, such larger amount as the Board of Directors in
  its discretion determines. All such agreements require the Company to provide
  the executive officer with various health, disability and life insurance
  benefits and the opportunity for incentive compensation based on the criteria
  set forth in the Company's MICP. (The Board of Directors of the Company
  terminated the MICP effective April 1, 1996.) All such agreements are
  effective as of April 1, 1995 and in each case supersede and replace any and
  all earlier employment agreements with such individuals.

      The agreements with Messrs. Branagan, Kinsey and White respectively
  provide that each executive officer will serve in his respective position for
  a three-year period. Each of the agreements with Messrs. Hein, Nerby and
  Swenson respectively provides that each executive officer will serve in his
  respective position for a four-year period. Each of the agreements with
  Messrs. Hein, Kinsey, Nerby, Swenson and White provides that, on the second
  anniversary of such agreement, the term of such agreement automatically will
  be extended for an additional year (or, in the case of Mr. Kinsey and Mr.
  White, an additional two years), and, thereafter, when only two years of such
  term as extended remain, the term of such agreement will again be extended for
  an additional year, such extensions continuing from year to year in the same
  manner, subject to the discretion of the Board of Directors not to so extend
  the term of any such agreement by prior written notice to the executive
  officer to which any such non-extended agreement pertains.

      Upon the occurrence of a change in control of the Company, the term of the
  agreements with each of Messrs. Hein, Nerby and Swenson is automatically
  reinstated to the four-year period provided for in each such agreement (and in
  the case of Mr. Kinsey and Mr. White, an additional four-year period),
  commencing upon the date of the change in control. Except for the agreement
  with Mr. Branagan, each of the agreements also provides for lump-sum,
  undiscounted cash payments and the continuation of certain other benefits
  following termination of the executive officer covered thereby without cause
  in connection with a change in control, which payments and benefits are to be
  equal to the then current rate of compensation and benefits provided for in
  any such agreement so terminated for the remaining term of any such agreement.

      For purposes of the agreements, a "change in control" is defined to mean
  (i) without prior approval of the Board of Directors of the Company, a single
  entity or group of affiliated entities acquires more than 50% of the voting
  stock of the Company issued and outstanding immediately prior to such

                                      50 
<PAGE>
 
  acquisition; (ii) the Board of Directors of the Company approves an
  unsolicited bid by a single entity or group of affiliated entities to acquire
  more than 50% of the voting stock of the Company issued and outstanding
  immediately prior to the approval of such acquisition, and such acquisition is
  consummated; (iii) the stockholders of the Company approve the consummation of
  any merger of the Company or any sale or other disposition of all or
  substantially all of its assets, if the stockholders of the Company
  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 the Company during any 24-month period without the
  approval of a majority of directors in office at the beginning of such period.

      In connection with the Getinge transaction, the Board of Directors of the
  Company has determined that the consummation of the tender offer would
  constitute a change in control for purposes of the employment agreements with
  the Company's executive officers. The cash amounts and other benefits payable
  by the Company to such officers following any termination of employment in
  connection with the change in control may not be fully deductible to the
  Company to the extent such payments and benefits exceed the limitations
  contained in Section 280G of the Internal Revenue Code. Each of the employment
  agreements was recently amended to permit the executive officer to refuse all
  or any portion of such payments and benefits to the extent that receipt of
  such amounts may result in adverse tax consequences to the executive officer.
  Under such amendments, the Company is relieved of the obligation to pay any
  amount which the executive officer so refuses in writing.

  Employee Benefit Plans

      The material which follows in this section describes certain provisions
  made by the Company pursuant to certain stock option, employee savings and
  retirement plans, now in effect, that provide for severance, termination or
  change in control benefits to employees, including the Named Executive
  Officers, other than group life and accident insurance, group hospitalization
  and similar group payments and benefits.

      Stock Option Plan.  Members of the Board of Directors, officers and other
  key employees of the Company are eligible to receive options to purchase up to
  an aggregate of 1,200,000 shares of the Company's Common Stock under the MDT 
  Corporation Amended and Restated 1987 Stock Option Plan (the "Stock Option 
  Plan"), which is administered by the Compensation Committee of the Board
  of Directors. The exercise price of each option granted must be at least the
  fair market value of the Common Stock at the date of grant (except that, with
  respect to 10% stockholders, the exercise price must be at least 110% of the
  fair market value), and no option may be exercised earlier than one year from
  the date of grant. Under the Stock Option Plan, in the event that a change in
  control occurs or, with respect to options awarded to officers and employees
  of the Company (other than Mr. Shamy), the Board of Directors determines in
  good faith that a change in control is about to occur, all outstanding options
  will be immediately exercisable by the option holder for the total remaining
  number of shares covered by options.

      For purposes of the Stock Option Plan, a "change in control" is defined to
  mean (i) without prior approval of the Board of Directors of the Company, a
  single entity or group of affiliated entities acquires more than 50% of the
  stock of the Company issued and outstanding immediately prior to such
  acquisition; (ii) the stockholders of the Company approve the consummation of
  any merger of the Company or any sale or other disposition of all or
  substantially all of its assets, if the stockholders of the Company
  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 (iii) a change in the majority of the
  Board of Directors of the Company during any 24-month period without the
  approval of a majority of directors in office at the beginning of such period.

                                      51
<PAGE>
 
      In connection with the Getinge transaction, the Board of Directors
  determined that, for purposes of the Stock Option Plan, a change in control
  was about to occur and, consequently, all options outstanding under the Stock
  Option Plan thereupon became immediately exercisable by the option holder. Any
  options remaining unexercised at the expiration of the tender offer period
  (currently scheduled for 5:00 p.m. EDT on July 25, 1996) shall terminate
  unless the tender offer is not successfully consummated (in which case such
  unexercised options will be treated as if no change in control occurred and
  will be governed by their original terms). Pursuant to the Merger Agreement,
  the Stock Option Plan will terminate at the effective time of the merger with
  Getinge.

      Supplemental Executive Retirement Plan.  Certain officers of the Company
  (except Mr. Shamy) and its subsidiaries also participate in the Company's
  Supplemental Executive Retirement Plan (the "SERP"). Except as provided below,
  the SERP provides a lump sum benefit at age 65 equal to the present value of
  annual payments for life equal to a "replacement percentage" of the
  participant's final base salary. Participants may also elect installment
  payments. The replacement percentage equals 50% (reduced for individuals who
  became officers on or after age 50) plus one-half of 1% for each year of
  service as an officer in excess of ten. This amount is reduced by the present
  value of the participant's social security benefit and the benefits payable
  from the Retirement Plan and the Savings and Thrift Plan. This resulting
  amount is then multiplied by the participant's vested percentage; a
  participant vests at the rate of 20% for each year of service as an officer
  after his second year of service as an officer. The SERP benefits are also
  payable after age 55 if the participant is vested (with a 5% reduction for
  each year that retirement precedes age 65). The Company has established a
  trust as a source of benefits to participants. The SERP states that the
  Company shall contribute no more than 20% of the participant's annual base
  salary on behalf of the participant plus the additional amounts that would
  have been contributed to the Retirement Plan and/or the Savings and Thrift
  Plan (described below) if the $150,000 compensation limit were not applicable.
  The Company's contributions to the SERP are voluntary.  The participant's
  retirement benefit shall equal the amount contributed on behalf of the
  participant plus or minus any earnings or losses. Such contributions are shown
  in the Summary Compensation Table in this Annual Report.

      Subject to the foregoing trust provisions, unless the Board of Directors
  of the Company otherwise determines, SERP benefits are also paid if there is a
  change in control and, within two years, the participant is involuntarily
  terminated, suffers a significant diminution of duties and responsibilities,
  has a downward change of title or is forced to relocate thereby resulting in
  his resignation. In this case, the participant is 100% vested and there is no
  early retirement reduction. For this purpose, a "change in control" is defined
  to mean (i) without prior approval of the Board of Directors of the Company, a
  single entity or group of affiliated entities acquires more than 50% of the
  stock of the Company issued and outstanding immediately prior to such
  acquisition; (ii) the Board of Directors of the Company approves an
  unsolicited bid by a single entity or group of affiliated entities to acquire
  more than 50% of the stock of the Company issued and outstanding immediately
  prior to the approval of such acquisition, and such acquisition is
  consummated; (iii) the stockholders of the Company approve the consummation of
  any merger of the Company or any sale or other disposition of all or
  substantially all of its assets, of the stockholders of the Company
  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 the Company during any 24-month period without the
  approval of a majority of directors in office at the beginning of such period.
  The Board of Directors has determined, and the SERP has been amended to
  provide, that these additional SERP benefits shall not be paid as a result of
  any transactions involving Getinge (including any change in a majority of the
  Board of Directors of the Company). 

      Retirement Plan.  The MDT Corporation Retirement Plan (the "Retirement
  Plan") is a profit sharing plan that covers all United States nonunion
  employees of the Company and its domestic subsidiaries. The Company's
  contributions to the Retirement Plan amount to three percent of each
  participant's compensation plus three percent of each participant's
  compensation in excess of the Social Security wage base. Compensation for this
  purpose is limited to $150,000. Amounts allocated to a participant's

                                      52
<PAGE>
 
  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, with 100% vesting after five years. Bankers Trust Company acts as
  trustee for the Retirement Plan. Vested amounts allocated to their accounts
  will be payable at retirement or other termination of service. The Company has
  no mandatory retirement age.  Effective as of July 1, 1996, the Retirement
  Plan was terminated, with the assets and administration of such plan with
  respect to hourly employees transferred to the MDT Corporation Savings and
  Thrift Plan for Hourly Employees (and that plan re-named the Retirement
  Savings Plan for Hourly Employees) and the assets and administration with
  respect to salaried employees transferred to the MDT Corporation Savings and
  Thrift Plan for Salaried Employees (and that plan re-named the Retirement
  Savings Plan for Salaried Employees).  The contributions, terms and conditions
  applicable under the former Retirement Plan (as described in this paragraph)
  will continue to apply under the Retirement Savings Plan for Hourly Employees
  and the Retirement Savings Plan for Salaried Employees, except that plan
  participants will now be able to direct the investment of these retirement
  funds.

      Retirement Savings Plan.  Salaried employees of the Company, including
  officers, are eligible to participate in the MDT Corporation Savings and
  Thrift Plan for Salaried Employees (which has as of July 1, 1996, been renamed
  the Retirement Savings Plan for Salaried Employees). Participants may
  contribute up to 6% of their compensation on a before-tax and/or after-tax
  basis. Compensation for this purpose is limited to $150,000. A participant
  will receive matching contributions from the Company of up to 50% of these
  contributions. Subject to certain limitations, participants may make
  additional contributions, which are not matched by the Company, equal to 10%
  of compensation on an after-tax basis or 12% of compensation on a before-tax
  basis. Contributions may be invested, at the election of the participant, in a
  guaranteed income fund, a balanced asset fund, a diversified equity fund, a
  bond fund or the Company's Common Stock. Company contributions vest at the
  rate of 20% after the first year of service and 20% for each subsequent year
  of service with 100% vesting at the end of five years. Company contributions
  are automatically vested upon the participant's death, total and permanent
  disability or attainment of age 65. Benefits under the Retirement Savings Plan
  for Salaried Employees become distributable to a participant or his
  beneficiary (in the case of death) upon termination of employment by reason of
  resignation, discharge, retirement, disability or death.

  Stock Options

      The Company did not grant stock options or SARs to any of the Named
  Executive Officers during the fiscal year ended March 31, 1996, nor did any of
  the Named Executive Officers exercise any stock options during such fiscal
  year or hold any "in-the-money" options as of the end of such fiscal year.

      The following table sets forth information concerning the number of
  unexercised options held by each of the Named Executive Officers on March 31,
  1996.

      In connection with the Getinge transaction, all outstanding options became
  immediately exercisable and will remain so until the expiration of the tender
  offer period. See "Employee Benefit Plans -- Stock Option Plan".

  Compensation Committee Interlocks and Insider Participation

      During the last completed fiscal year, the Compensation Committee
  consisted of Messrs. Jones, Gilbertson and Shamy. Mr. Shamy is Secretary of
  the Company and its subsidiaries. Mr. Shamy is paid a fee of $1,000 per month
  for his services as Secretary.  He was not eligible to receive bonus
  compensation under the MICP (which was terminated by the Board of Directors
  effective on April 1, 1996).

  Directors Compensation

      Each of the directors, other than Mr. Branagan, receives a retainer fee of
  $1,500 per month and fees of $1,000 for each meeting of the Board of Directors
  and (except as set forth below with respect to meetings of, among other
  committees, the Negotiating Committee) $500 for each meeting of a committee of
  the Board of Directors that the director attends. Each director who chairs a
  committee of the Board of Directors receives an additional fee of $250 for
  each meeting of the committee which the director attends and chairs. Directors
  are reimbursed for travel and other expenses related to attendance at Board
  and committee meetings. In connection with the Getinge Transaction and the
  negotiation of the Merger Agreement, the Board of Directors appointed a
  special Negotiating Committee consisting of Messrs. Branagan, Johnson and
  French. Messrs. Johnson and French may receive additional compensation for
  their service on such committee in an amount to be determined by the Board of
  Directors. Such compensation is expected to be paid at a rate of $250 per hour
  ($1,000 per day maximum) for participation in any meeting which has as its
  subject the business of the Negotiating Committee.

      Non-employee directors of the Company (including, for these purposes, Mr.
  Shamy) are also automatically entitled to receive grants of nonqualified stock
  options under the Company's Stock Option Plan. Each non-employee who becomes a
  director after the 1993 Annual Meeting of Stockholders is automatically
  granted upon his or her initial election or appointment to the Board of
  Directors an option to purchase 5,000 shares of the Company's Common Stock.
  Following his election as a director in 1995, Dr. Mark received an option to
  purchase 5,000 shares of the Company's Common Stock at an exercise price of
  $6.625 per share. Annually, but subject to certain limitations described
  below, each non-employee director is also automatically granted an option to
  purchase the nearest number of whole shares of Common Stock (up to a maximum
  of 1,500 shares per director per year) determined by dividing the non-employee
  directors' average annual compensation (i.e., the average of the aggregate
  amount of fixed retainer and attendance fees that all nonemployee directors
  received for serving as directors of the Company in the immediately preceding
  year) by the fair market value per share of the Company's Common Stock on the
  grant date, which is the fifth business day following the date of the public
  release by the Company of its annual statement of sales and earnings.
  Notwithstanding the foregoing, (a) no annual grants of options shall be made
  to non-employee directors for any fiscal year unless the Company's earnings
  per share for such fiscal year are equal to or greater than the average of the
  Company's earnings per share for the immediately preceding three fiscal years,
  (b) the maximum number of shares which may be granted to any individual non-
  employee director under the Stock Option Plan shall not exceed 1% of the
  Company's total issued and outstanding Common Stock, and (c) the maximum
  number of shares which may be granted to all directors of the Company shall
  not exceed in the aggregate one-half of the total shares issuable under the
  Stock Option Plan. Annual option grants that would otherwise exceed the limits
  described in (b) and (c) above shall be prorated within such limitations. None
  of the directors received an option grant pursuant to this formula with
  respect to Fiscal Year 1994, Fiscal Year 1995 or Fiscal Year 1996.

                                      54
<PAGE>
 
      The purchase price per share of Common Stock covered by any option granted
  to a non-employee director pursuant to the Stock Option Plan is payable in
  cash and/or shares and equals the fair market value per share of the Common
  Stock on the grant date. The options become exercisable 12 months after the
  grant date and, unless earlier terminated, terminate on the date which is the
  earlier of (i) five years from the grant date, or (ii) the date of adoption by
  the Board of Directors of a plan of complete liquidation of the Company's
  assets. The Board of Directors, subject to plan limits, retains discretion to
  modify the terms of outstanding options and to reprice the options.

      In the event a non-employee director's services as a Board member are
  terminated for any reason other than fraud, dishonesty or death, then any
  options granted to the non-employee director pursuant to the Stock Option
  Plan, to the extent such options had become exercisable on the date of such
  termination, continue to be exercisable for a period of three months
  thereafter or the balance of the option term, whichever period is shorter. If
  the holder of the option dies while serving as a director of the Company, or
  within not more than three months after the termination of such status, then
  any such options, to the extent they had become exercisable on the date of
  death, continue to be exercisable by the director's descendants, heirs or
  personal representatives for a period of 12 months after the date of death or
  the balance of the option term, whichever period is shorter. In the event the
  option holder's directorship is terminated for fraud or dishonesty, all of the
  holder's unexercised options expire as of the date of termination.

      The Stock Option Plan contains provisions relating to adjustments for
  changes in the Company's Common Stock upon certain specified events, including
  mergers, reorganizations, recapitalizations, stock splits, stock dividends and
  similar events. In addition, the Stock Option Plan provides that each option
  granted to a non-employee director will become immediately exercisable for a
  period of 30 days following any "change in control" of the Company as defined
  in the Stock Option Plan (see "Employee Benefit Plans -- Stock Option Plan").
  In connection with the Getinge transaction and the proposed merger, the Board
  of Directors determined that, for purposes of the Stock Option Plan, a change
  in control was about to occur and, consequently, all options outstanding under
  the Stock Option Plan thereupon became immediately exercisable by the option
  holder. Each non-employee director has acknowledged to the Company that any
  options remaining unexercised at the expiration of the tender offer period
  (currently scheduled for 5:00 p.m. EDT on July 25, 1996) shall terminate
  unless the tender offer is not successfully consummated (in which case such
  unexercised options will be treated as if no change in control occurred and
  will be governed by their original terms). Pursuant to the Merger Agreement,
  the Stock Option Plan will terminate at the effective time of the merger with
  Getinge.

  Changes of Control

      On May 12, 1996, the Company announced that it had entered into an
  Agreement and Plan of Merger (the "Merger Agreement") pursuant to which it is
  proposed to be acquired by Getinge Industries AB, a Swedish manufacturer of
  hospital and scientific equipment. Getinge commenced a tender offer on May 17,
  1996, for all outstanding shares of the Company Common Stock for a cash price
  of $4.50 per share. On July 12, 1996, Getinge announced an extension of its
  tender offer until July 25, 1996 and an increase in the offer price to $5.50
  per share. Consummation of the tender offer and the merger is subject to
  certain terms and conditions set forth in the Merger Agreement, including
  approval of the holders of two-thirds of the shares to be acquired and
  regulatory approvals. If the tender offer is consummated, those shares not
  acquired in the tender offer will be converted into $5.50 in cash pursuant to
  a merger to be effected following completion of the tender offer.

                         INDEPENDENT AUDITORS' REPORT
                         ----------------------------


The Board of Directors and Stockholders
MDT Corporation:

Under date of May 17, 1996, except as to the third paragraph of Note 9 and the
second paragraph of Note 17, which are as of July 12, 1996, we reported on the
consolidated balance sheets of MDT Corporation and subsidiaries as of March 31,
1996 and 1995, and the related consolidated statements of income (loss),
stockholders' equity, and cash flows for each of the years in the three-year
period ended March 31, 1996. These consolidated financial statements and our
report thereon are incorporated by reference in the annual report on Form 10-K
for the year 1996. Our report contains an explanatory paragraph that states that
the status of the Company's existing credit facilities and the need for
borrowing capacity during fiscal 1997 raise substantial doubt about the
Company's ability to continue as a going concern. The consolidated financial
statements do not include any adjustments that might result from the outcome of
this uncertainty. In connection with our audits of the aforementioned
consolidated financial statements, we have also audited the related financial
statement schedule 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.

        WHEREAS, MDT Corporation ("MDT") maintains the MDT Corporation

<PAGE>
 
4.5 - Limitation of Retirement Benefits.
      ---------------------------------


        Notwithstanding anything contained herein to the contrary, including 
Section 4.1, each Participant's benefit under this Plan shall equal the amounts 
contributed, if any, on behalf of such Participant, if any, to the trust 
established by the Company with respect to the Plan, plus any earnings or minus 
any losses.  The Company shall contribute no more than the sum of the following 
amounts on behalf of each Participant:

        (a)  for each Plan Year, twenty percent (20%) of the Participant's 
    Annual Base Salary (excluding Annual Base Salary payable after attainment
    age 65).

        (b)  for each calendar year beginning on or after January 1, 1994,
    the excess of (i) the employer "retirement contributions" that would have
    been made to the MDT Corporation Retirement Plan (for the period prior to
    July 1, 1996) and the Savings Plan, as defined in (c) below (for the Period
    thereafter), if the limits on compensation under Section 401(a)(17) of the
    Internal Revenue Code of 1986, as amended (the "Code"), were not in effect,
    over (ii) the actual employer retirement contributions made by the Company
    to the Retirement Plan and Savings Plan on behalf of such Participant; and



                                        2

<PAGE>
 
        (c)     for each calendar year beginning on or after January 1, 1996, if
the Participant makes the maximum basic deposit permitted (subject to all tax
limitations) to the MDT Corporation Retirement Savings Plan for Salaried
Employees (formerly, the MDT Corporation Savings and Thrift Plan for Salaried
Employees) ("Savings Plan") while eligible to participate, the excess of (i) the
employer matching contributions that would have been made to the Savings Plan if
Code Section 401(a)(17) were not in effect and the Participant made the maximum
basic deposit permitted (subject to all tax limitations other than Code Section

made to the Savings Plan if the Participant made deposits equal to 6% of his
compensation, as defined in the Savings Plan, but not in excess of the maximum
permitted under Code Section 402(g). This Clause (c) shall be interpreted to
avoid making Participants whole if they are adversely affected by the various
nondiscrimination tests applicable to basic deposits or matching contributions."

                       AMENDMENT TO EMPLOYMENT AGREEMENT
                       ---------------------------------

    The Employment Agreement ("Agreement") dated and executed as of April 1, 
1995 by and between MDT CORPORATION ("Employer") and WILLIAM T. HILVERT is 
hereby amended and restated, in part, as follows:

     WHEREAS, the Employment Agreement provides for the Employee's participation
in the Management Incentive Compensation Plan ("MICP") subject to the terms of 
the MICP.

     WHEREAS, Employer has terminated the MICP effective at the close of Fiscal 
Year 1996;

     WHEREAS, Employer expects to adopt a new discretionary bonus program;

     WHEREAS, Employee would like to be eligible to participate in the new 
discretionary bonus program;

     WHEREAS, Employer and Employee hereby agree to amend and restate the 
Employment Agreement to reflect the elimination of the MICP.

     NOW THEREFORE, Employer and Employee hereby agree as follows:

     1.   Subparagraph 4(b) of the Agreement is hereby deleted in its entirety.

     2.   Subparagraphs 4(c), 4(d) and 4(e) of the Agreement shall be renumbered
as subparagraphs 4(b), 4(c) and 4(d), respectively.

     3.   Subparagraphs 10(c) of the Agreement is hereby amended and restated as
follows:
     
    
<PAGE>
 
         (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 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 the Agreement without
cause, Employer's sole obligation shall be to pay Employee the salary in effect
at that time of his termination, in semi-monthly installments and to provide
healthcare and life insurance benefits and to continue his participation in the
Retirement Plan, as amended or as merged into Employer's 401(k) Plan (provided
that if contributions cannot be made under applicable law, cash payments equal
to such contributions shall be made to Employee), 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
<PAGE>
 
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 and to provide healthcare and life insurance
benefits and to continue his participation in the Retirement Plan, as amended,
or as merged into Employer's 401(k) Plan (provided that if contributions cannot
be made under applicable law, cash payments equal to such contributions shall be
made to employee), 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.

          Notwithstanding the foregoing, Employee shall be entitled to refuse
all or any portion of any payment or other benefit (as selected by Employee in
his sole discretion) under this Agreement if he or she determines that receipt
of such payment may result in adverse tax consequences to him or her. The
Employer shall be totally and permanently relieved of any obligation to pay any
amount which Employee explicitly so refuses in writing. 

     4.   The Agreement, as amended and restated herein, shall remain in full
force and effect.
<PAGE>
 

IN WITNESS WHEREOF, Employer and Employee have executed this Amendment to 
Employment Agreement as of this 10th day of May, 1996.

     Lessor hereby releases Lessee from all liability arising out of loss of or 
damage to the 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 OF FAILURE TO ACT OF 
LESSEE, ITS OFFICERS, EMPLOYEES, AGENTS AND/OR REPRESENTATIVES). Lessor, with 
the consent of its insurance carriers, 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 Lessee on request. Lessee hereby releases Lessor from all 
liability arising out of loss or damage to property of Lessee located on the 
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

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

     If, during the term of this lease, the 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 the Premises to the
operable condition for which the 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, first causing the Premises to be restored to the
operable condition for which the Premises were being used at the time of the
destruction or damage; and, second substantially returning 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 Premises shall be destroyed or damaged, or partially
destroyed or damaged, to such an extent that the repair of such destruction or
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 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 the 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 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 and to the extent that the Lessor cannot make such repairs 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 the whole of the Premises or the whole of the building included in the 
Premises 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 included in the Premises shall be taken
or condemned by any competent authority for any public or quasi-public use or 
purpose and the part so taken cannot be replaced at some other location on the 
Premises, within ninety (90) days after such taking, by the exercise of 
reasonable diligence by the Lessor, so as to render the Premises, after 
replacing the part of the building so taken at the new location of the Premises,
suitable for use by the Lessee for the purpose for which the 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 Premises other than the 
building or any part of the Premises other than the building shall be taken or 
condemned by an competent authority for any public or quasi-public use or 
purpose so as to render the remaining portion of the Premises unsuitable for use
by the Lessee for the purpose for which the 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 Premises adjoining the street
or road upon which the 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 Premises unsuitable for use by the Lessee for the purpose for which the
Premises were or condemnation, if Lessor shall make suitable replacement parking
available to Lessee, within a reasonable distance, from the 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 Premises, shall likewise
not be construed as rendering the remaining portion of the Premises unsuitable
for the use of the Lessee for the purpose for which the 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 Premises unavailable for the use by the Lessee for the
purpose for which the 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 shall 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

nor Lessor shall have any rights in any award made to the other by any 
condemnation authority.

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

     In the event a voluntary or involuntary petition in bankruptcy is filed by
or 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 make an
assignment for the benefit of creditors, Lessor reserves the right to terminate
this Lease forthwith and without notice.

     Lessee shall have the right to assign this lease and to sublet the 
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 so long as the 
sub-Lessee used the Premises in a manner consistent with the within lease.

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 the 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 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.

shall not deface or injure the Premises, or do anything or permit anything to be
done upon the Premises which shall create a nuisance.

                                      14.

               RELEASE FROM LIABILITY AND WAIVER OF SUBROGATION
               ------------------------------------------------

     Lessor hereby releases Lessee from all liability arising out of loss of or 
damage to the 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 OF FAILURE TO ACT OF 
LESSEE, ITS OFFICERS, EMPLOYEES, AGENTS AND/OR REPRESENTATIVES). Lessor, with 
the consent of its insurance carriers, 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 Lessee on request. Lessee hereby releases Lessor from all 
liability arising out of loss or damage to property of Lessee located on the 
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, and agrees to obtain 
written evidence of such consent to waiver from its insurance carriers and to

     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.
                                      
                                      15.

                                     -----

     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 
personal and/or real property belonging to Lessor and located at or upon the 
Premises to the extent that such real property taxes and assessments exceed 
Twelve Thousand Four Hundred Ninety and 58/100 ($12,490.58) Dollars per 
year.

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

     If, during the term of this lease, the 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 the Premises to the
operable condition for which the 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, first causing the Premises to be restored to the
operable condition for which the Premises were being used at the time of the
destruction or damage; and, second substantially returning 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 Premises shall be destroyed or damaged, or partially
destroyed or damaged, to such an extent that the repair of such destruction or
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 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 the 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 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 and to the extent that the Lessor cannot make such repairs 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

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

     If the whole of the Premises or the whole of the building included in the 
Premises 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 included in the Premises shall be taken
or condemned by any competent authority for any public or quasi-public use or 
purpose and the part so taken cannot be replaced at some other location on the 
Premises, within ninety (90) days after such taking, by the exercise of 
reasonable diligence by the Lessor, so as to render the Premises, after 
replacing the part of the building so taken at the new location of the Premises,
suitable for use by the Lessee for the purpose for which the 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 Premises other than the 
building or any part of the Premises other than the building shall be taken or 
condemned by an competent authority for any public or quasi-public use or 
purpose so as to render the remaining portion of the Premises unsuitable for use
by the Lessee for the purpose for which the 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 Premises adjoining the street
or road upon which the 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 Premises unsuitable for use by the Lessee for the purpose for which the
Premises were or condemnation, if Lessor shall make suitable replacement parking
available to Lessee, within a reasonable distance, from the 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 Premises, shall likewise
not be construed as rendering the remaining portion of the Premises unsuitable
for the use of the Lessee for the purpose for which the 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 Premises unavailable for the use by the Lessee for the
purpose for which the 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 shall 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

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 by
or 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 make an
assignment for the benefit of creditors, Lessor reserves the right to terminate
this Lease forthwith and without notice.

                                      19.

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

     Lessee shall have the right to assign this lease and to sublet the 
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 so long as the 
sub-Lessee used the Premises in a manner consistent with the within 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 Premises for the term provided for in 
Article 2 hereof.

                                      22.

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

     In the event of default at any time by Lessee in the payment of the rent

of the Premises, or;

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

     (3) re-enter the 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 the 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 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.

                                      23.

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.

Premises caused by perils ordinarily covered under fire and extended coverage 
insurance policies (including, without limitation, any such loss or damage

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

     If, during the term of this lease, the 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 the Premises to the
operable condition for which the 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, first causing the Premises to be restored to the
operable condition for which the Premises were being used at the time of the
destruction or damage; and, second substantially returning 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 Premises shall be destroyed or damaged, or partially
destroyed or damaged, to such an extent that the repair of such destruction or
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 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 the 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 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 and to the extent that the Lessor cannot make such repairs 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 the whole of the Premises or the whole of the building included in the 
Premises 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 included in the Premises shall be taken
or condemned by any competent authority for any public or quasi-public use or 
purpose and the part so taken cannot be replaced at some other location on the 
Premises, within ninety (90) days after such taking, by the exercise of 
reasonable diligence by the Lessor, so as to render the Premises, after 
replacing the part of the building so taken at the new location of the Premises,
suitable for use by the Lessee for the purpose for which the 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 Premises other than the 
building or any part of the Premises other than the building shall be taken or 
condemned by an competent authority for any public or quasi-public use or 
purpose so as to render the remaining portion of the Premises unsuitable for use
by the Lessee for the purpose for which the 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 Premises adjoining the street
or road upon which the 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 Premises unsuitable for use by the Lessee for the purpose for which the
Premises were or condemnation, if Lessor shall make suitable replacement parking
available to Lessee, within a reasonable distance, from the 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 Premises, shall likewise
not be construed as rendering the remaining portion of the Premises unsuitable
for the use of the Lessee for the purpose for which the 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 Premises unavailable for the use by the Lessee for the
purpose for which the 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 shall 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

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 by
or 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 make an
assignment for the benefit of creditors, Lessor reserves the right to terminate
this Lease forthwith and without notice.

                                      19.

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

     Lessee shall have the right to assign this lease and to sublet the 
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 so long as the 
sub-Lessee used the Premises in a manner consistent with the within 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 Premises for the term provided for in 
Article 2 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 Premises, or;

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

     (3) re-enter the 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 the 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 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.

                                      23.

                     WAIVER OF BREACH AND TIME OF ESSENCE
                     ------------------------------------

     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.

be made for any tax exemption granted to LESSOR), and to pay, or cause to be 
paid, any and all taxes of whatever nature levied against the personal property,

and/or service on the mechanical, plumbing, electrical, and HVAC equipment

Premises (as the case may be) as Additional Rent.

                                       2
<PAGE>
 
     7.2.2. In the event that LESSOR shall perform and/or provide any repairs, 
maintenance, service and/or replacement for which LESSEE is responsible under 
subsection 7.2.1. of this Lease, LESSEE shall pay LESSOR the cost of any such 
repairs, maintenance, service and/or replacement as Additional Rent.

     7.2.3. Notwithstanding the provisions of subsections 7.2.1. and 7.2.2. and 
as an alternative thereto, LESSOR and LESSEE may agree that LESSOR may purchase,
at LESSEE'S expense, a service policy or policies providing for the repair, 
maintenance, service and/or replacement of the mechanical, plumbing, electrical
and HVAC equipment and/or systems located in and/or otherwise servicing the 
Premises during the term of this Lease or any renewal.  If LESSOR and LESSEE so 
agree, then LESSEE shall pay LESSOR as Additional Rent, the full cost of any 
policy or policies covering equipment and/or systems which service the Premises 
exclusively, and LESSEE'S Proportionate Share of the cost of any policies
covering equipment and/or systems which otherwise service the Premises. Upon the
purchase of such policy or policies, and so long as they remain in force, LESSEE
pays all of such Additional Rent charges, and LESSEE, its agents, servants
and/or employees do not engage in any conduct which would contravene, void and
otherwise affect such policies, LESSEE shall not be responsible for the cost of
any necessary repairs, maintenance, service and/or replacement of the equipment
and/or systems except for such repairs, maintenance, service and/or replacement
as may be necessitated by an intentional or negligent act or omission on the
part of the LESSEE, its agents, servants and/or employees and/or which are not
covered by such policy or policies.

     7.2.4. Notwithstanding the provisions of subsection 7.2.2. and/or any other
provisions of this Lease, nothing in this Lease shall be construed or 
interpreted as any agreement and/or undertaking by LESSOR to repair, service 
and/or maintain the Premises and/or its systems and/or appurtenances during the 
term of this Lease or any renewal.

     7.3. LESSEE agrees to replace any plate, window or door glass broken in the
Premises, with glass of like kind and quality, except when said plate, window or
door glass is broken by reason of defective construction of the Building, or due
to negligent repair of the Building by LESSOR.  LESSEE shall further obtain and 
maintain during the term of this Lease and any renewal, at LESSEE'S expense, 
plate glass insurance on the Premises in such amount and with such insurer as 
may be satisfactory to LESSOR.  If LESSOR so requires LESSOR shall be designated
as a named insured on any such policy of insurance upon LESSOR'S request.  In 
the alternative, and at LESSOR'S option, LESSOR may purchase such insurance and 
LESSEE shall pay LESSEE'S Proportionate Share of the cost of such insurance to 
LESSOR as Additional Rent hereunder.

     7.4. LESSEE shall pay LESSOR as Additional Rent LESSEE'S Proportionate 
Share of the cost of all common area services, maintenance and repairs 
including, without limitation, refuse and trash removal.

at such earlier time as LESSOR may agree, LESSEE may make such other 
improvements to the premises in preparation for and in the conduct of its 
business as LESSEE deems necessary and/or appropriate, at LESSEE'S expense, 
subject to LESSOR'S prior written consent.  LESSEE warrants that any and all 
such alterations, additions and/or improvements made pursuant to this subsection
shall be made in a good, workmanlike manner and in full and complete compliance 
with all laws, rules, regulations, and ordinances and in satisfaction of the 
requirements of such building, fire, safety, health and other codes as may now 
be or hereafter become applicable, without cost to LESSOR.  All alterations, 
additions and improvements shall become the property

                                       3
<PAGE>
 
of the LESSOR; however, upon written notice by LESSOR to LESSEE prior to the 
expiration of this Lease and/or renewal, LESSEE agrees to remove such 
alterations, additions and improvements and to restore the Premises to its 
original condition at LESSEE'S expense, normal wear and tear excepted.

     8.3. By executing this Lease, LESSEE acknowledges that, LESSEE has
inspected the Premises (except for the alterations, additions and improvements
provided for by Section 8.1.), that they are in good order and repair, and that
LESSEE accepts them "as is" and waives any defects therein.

     8.4. If any mechanic's lien, materialmen's lien or other lien is filed
against the Premises, the Building, the property upon which the Building is
located and/or any portions thereof, by reason of any work, labor, equipment,
materials and/or services, furnished and/or alleged to have been furnished to or
for LESSEE or for any changes, alterations, additions, improvements and/or
repairs made by LESSEE, LESSEE shall cause said lien to be released of record
within five (5) days after the filing of such lien. LESSEE shall further
indemnify and hold LESSOR harmless from any and all claims, demands, suits,
actions, losses, liability and damages arising out of and/or relating to any
such lien or claim of lien.

     9. TRADE AND OTHER FIXTURES. LESSEE may, at LESSEE'S expense, install or
        ------------------------
cause to be installed such equipment, machinery, trade and/or other fixtures as
are reasonably necessary for the operation and conduct of LESSEE'S business. Any
such trade fixtures shall remain LESSEE'S personal property and may be removed
by LESSEE, provided that LESSEE shall repair at LESSEE'S expense any damage to
the Premises resulting from the installation and/or removal of such trade
fixtures.

     10. CASUALTY DAMAGE. Upon the occurrence of any casualty, damage or
         ---------------
destruction affecting the Premises, LESSEE shall give immediate notice to
LESSOR. If, in the opinion of LESSOR, the Premises are rendered substantially
unfit for occupancy or use by any such casualty, damage or destruction, or
LESSOR should decide not to rebuild or remodel the Premises, this Lease shall
cease and Base Rent and Additional Rent shall abate from the occurrence of such
casualty or vacation of the Premises, whichever is later. If, in the opinion of
LESSOR, the Premises are not thereby rendered substantially unfit for occupancy
or use, LESSOR shall promptly and diligently restore so much of the Premises as
was damaged to its condition at the commencement of this Lease, exclusive of the
Tenant Improvement Items, with no abatement of rent.

    11. FIRE INSURANCE. LESSOR shall provide, and pay the premiums for, fire
        --------------
and extended coverage to protect the Building with coverage amounts and with an
insurer satisfactory to LESSOR. LESSEE will not do anything in or about the
Premises that will contravene or affect any insurance which LESSOR may place
thereon. LESSEE will pay as Additional Rent its Proportionate Share of such
insurance upon being billed therefor by LESSOR and shall pay the entire cost of
any increase in the insurance premium due to LESSEE'S use of the premises.

    12. INSURANCE AND LIABILITY.
        -----------------------

    12.1. LESSEE, at LESSEE'S sole expense, shall maintain in force continuously
throughout the term of this Lease and/or any renewal, a comprehensive general
liability policy with respect to the Premises and LESSEE'S occupancy, use and/or
operations of, on and/or about the Premises, in such amounts as LESSOR may
require from time to time but in no event less than $500,000.00 for any one
person and $1,000,000.00 for any one occurrence with respect to death, bodily
injury and/or personal injury and $100,000.00 for each occurrence with respect
to damage and/or destruction of property; such insurance shall be with an
insurer satisfactory to LESSOR and shall include coverage for and/or against
assumed and/or contractual liability under this Lease. Such insurance shall
include LESSSOR and LESSOR'S management agent as named insured and LESSEE shall
promptly furnish LESSOR with a Certificate from the insurer that such insurance
is in effect. In the event that the

                                       4
<PAGE>
 
insurer imposes any premium charge on LESSOR and/or LESSOR pays the premium for 
such insurance, LESSEE shall reimburse LESSOR for such charges; LESSEE shall pay
such charges as Additional Rent.  LESSEE shall be responsible for LESSEE'S 
Proportionate Share of the cost of any public liability insurance maintained by 
LESSOR with respect to the Building and property on which it is situated.

     12.2. LESSOR and its management agent shall not be liable and/or 
responsible for, and LESSEE shall indemnify and hold LESSOR and its management 
agent harmless against any and all damages and claims for damages, including 
but not limited to damages and/or claims for damages for the death, bodily 
injury and/or personal injury to any person and/or any injury, loss and/or 
damage to any property occurring on and/or relating to or arising out of 
LESSEE'S occupancy and/or use of the Premises, the Building and/or their 
appurtenances, unless such death, bodily injury, personal injury and/or injury, 
loss or damage to property and other damage was proximately caused by the 
negligent and/or intentionally tortious act or omission of the LESSOR, its 
management agent and/or some agent, servant, and/or employee for whose conduct 
they are legally responsible.  Notwithstanding the foregoing, LESSOR and its 
management agent shall not be liable and/or responsible for any such damages 
and/or claims for damages for any such injury, loss and/or damage occurring on 
or about the Premises, the Building and/or their appurtenances, regardless of 
whether such injury, loss and/or damage was proximately caused by the
negligent act or omission of LESSOR and its management agent and/or an agent,
servant, and/or employee for whose conduct they are legally responsible, where
such Premises, Building and/or appurtenances are within the exclusive control of
LESSEE.

     12.3. LESSEE further agrees that LESSOR shall not be liable and/or 
responsible for, and to hold LESSEE harmless against any and all intentionally 
tortious and/or negligent acts and/or omissions of any other persons leasing
from LESSOR and their agents, servants, employees, contractors, invitees, and/or
visitors.

     13.  COMPLIANCE WITH LAWS.  LESSEE agrees to promptly comply with all 
          --------------------
applicable and valid laws, ordinances and regulations of any and all Federal, 
State, County, Municipal or other lawful authorities pertaining to the use and 
occupancy of the Premises.

     14.  ASSIGNMENT AND SUBLETTING.  LESSEE shall not assign this Lease or 
          -------------------------
allow the same to be assigned by operation of law or otherwise, or sublet the 
Premises or any part thereof, or use of permit same to be used for any purpose 
other than as above specified, without LESSOR'S prior written consent, which 
consent may be withheld in LESSOR'S sole discretion.  Any such assignment or 
sublease which is made without LESSOR'S consent shall be void and of no force 
and effect.  Any such assignment or sublease which is made with LESSOR'S consent
shall be subject to all of the terms and conditions of this Lease.  If any 
partnership interest in, or any corporate share of stock of LESSEE are 
transferred by sale, assignment, bequest, inheritance, operation of law or 
otherwise, so as to result in a change of the voting control of LESSEE by those 
owning a majority of the interest in LESSEE as of the date hereof, such transfer
shall constitute an assignment for the purposes hereof and shall require 
LESSOR'S prior written consent thereto.  In any event, LESSEE shall notify 
LESSOR of such change of control and LESSOR may terminate this Lease at any time
thereafter upon sixty (60) days' prior written notice to LESSEE.

     15.  BANKRUPTCY.  Should LESSEE make an assignment for the benefit of 
          ----------
creditors, file for bankruptcy, or have any involuntary petition in bankruptcy 
filed against it, such action shall constitute a breach of the Lease, which 
shall automatically terminate all rights of LESSEE under this LEASE.  Upon the 
filing of a petition by or against LESSEE under the Federal Bankruptcy Code (or 
any successor federal bankruptcy statute), LESSEE, as debtor and/or as debtor in
possession, and any trustee who may be appointed, agree to perform each and 
every obligation of LESSEE under this Lease, including, but not limited to, the 
payment of all monetary obligation hereunder, until such time as this Lease is 
either rejected or assumed by order of a United States Bankruptcy Court, or 
other federal court having jurisdiction over bankruptcy matters.

     16.  EMINENT DOMAIN.  If all or any part of the Premises are taken under 
          --------------
power of eminent domain or conveyed under threat of condemnation proceedings and
LESSOR shall determine that the remainder of the Premises is inadequate or 
unsatisfactory for the purpose of this Lease, then this Lease shall terminate
effective as of the date LESSEE is required to give up the right to occupy or 
use the Premises.  LESSEE shall have no right to make any claim against LESSOR 
because of such termination, nor to participate in any awards.

     17.  ATTORNEYS' FEES.  LESSEE shall pay LESSOR all costs, expenses and 
          ---------------
charges incurred by LESSOR in collecting any sums due LESSOR under this Lease,
and/or enforcing any provisions of this Lease, and/or recovering any damages
and/or losses from LESSEE to which LESSOR is legally entitled, including, but
not limited to, reasonable attorneys' fees.

     18.  DEFAULT.
          -------

     18.1. In the case of any default of LESSEE in any of the terms and/or
conditions of this Lease (other than any default occasioned by the institution
of bankruptcy proceedings and/or an assignment for the benefit of creditors
which shall be governed by Section 15 of this Lease), LESSOR, at LESSOR'S
option, may recover the Premises if such default continues uncured for a period
of ten (10) days after LESSOR notifies LESSEE of such default and of LESSOR'S
intention to recover the Premises. Upon the giving of such notice and the
expiration of such ten (10) day period, unless LESSEE shall have cured the
default during that time, LESSOR shall be entitled to repossess and/or relet the
Premises as the agent of LESSEE for any balance of the then term and collect
rent therefor. And in any event, the LESSOR may distrain, by any legal means,
for any overdue installment of rent or rental payment and may enter the property
for such purpose by force if necessary without liability, which liability is
hereby expressly waived. In the event of reletting by the LESSOR as agent for
the LESSEE, the reletting shall be on such terms, conditions and rentals as the
LESSOR deems proper, and the proceeds that may be collected from same, less the
expense of reletting, including any broker's commission and costs for the
repair, restoration and/or preparation of the Premises for reletting, shall be
applied against the rental to be paid by LESSEE, and LESSEE shall be liable for
any balance that may be due under this Lease or any renewal, and such reletting
shall not operate as termination of this Lease or any renewal or as a waiver or
postponement of any right of LESSOR against the LESSEE. Any recovery of the
Premises, institution of proceedings to recover the Premises, re-entry,
repossession and/or reletting hereunder shall not operate as, nor shall it be
interpreted or construed as a termination of this Lease or any renewal, and
shall not relieve LESSEE of its liability and obligations under this Lease and
LESSEE shall in all events remain liable for the full amount of Base Rent and
Additional Rent provided for in this Lease and for any deficiency or loss of
such rent; LESSOR, at LESSOR'S option, may recover such rent and/or damages for
the loss of rent in separate actions from time to time as LESSEE'S liability
and/or obligation to pay rent accrue or would have accrued had LESSEE not
defaulted. Any such recovery, institution of legal proceedings, re-entry,
repossession, and/or reletting shall be in addition to and without prejudice to
any rights and/or remedies which LESSOR may otherwise have.

     18.2. Notwithstanding any provision of Section 18.1. to the contrary, 
LESSOR shall be entitled immediately upon a default by LESSEE to avail himself 
of all rights and remedies afforded LESSOR by this Lease and/or law, without any
notice to LESSEE and without giving LESSEE any grace period if such default 
arises under Section 15 of this Lease, or if LESSEE has defaulted in and/or 
breached the same and/or any other term and/or condition of this Lease during 
the twelve (12) months preceding such current default and for which notice was 
given (whether or not subsequently cured), or if such default is of such a 
nature as to give rise to an emergency situation which in LESSOR'S reasonable 
judgment requires LESSOR to take immediate action to cure such default.

     19.  HOLDING OVER.  Should LESSEE continue to occupy the Premises, or any 
          ------------
portion thereof, after the termination of this 

                                       6
<PAGE>
 
Lease (and/or any renewal) and unless otherwise agreed in writing, LESSEE shall 
pay LESSOR on demand an amount equal to two hundred percent (200%) of the rent 
due for the last full month of the term of this Lease (or renewal) for each 
month or portion thereof that LESSEE continues to occupy all or any part of the 
Premises.  Such payments shall not be deemed to be rent and acceptance of any 
such payments by LESSOR shall not be deemed or construed to convert LESSEE into 
a month to month tenant or otherwise grant LESSEE any right to remain in 
possession of the Premises or so as to otherwise impair LESSOR'S right to the 
immediate possession of the Premises.  Similarly, any such payments shall be in 
addition to and without prejudice to LESSOR'S right to recover any damage to 
which LESSOR otherwise would be entitled as a result to LESSEE'S holding over.

     20.  CPI CLAUSE.  The annual Base Rent, and the monthly installments 
          ----------
thereof, shall be increased on the first anniversary of this Lease and each and 
every anniversary thereafter by the greater of (i) six percent (6%) or (ii) the 
percentage increase in the Consumer Price Index (defined below) over the year 
which ends on or about said anniversary date.  The Consumer Price Index shall 
mean the "Consumer Price Index for All Urban Consumers (CPI-U), for Washington, 
D.C. SMSA, All Items 1982-84-100" as issued by the Bureau of Labor Statistics of
the United States Department of Labor.  In the event that the Consumer Price 
Index is replaced and/or discontinued, the term Consumer Price Index is replaced
and/or discontinued, the term Consumer Price Index as used herein shall also 
mean such other replacement or substitute index as may be issued and/or adopted 
by the Bureau of Labor Statistics of the United States Department of Labor.

     21.  RIGHT OF ENTRY.  Notwithstanding any other provisions of this Lease 
          --------------
to the contrary, LESSOR and its agents shall have the right to enter the
Premises at any reasonable times to inspect the Premises, to exhibit the
Premises to any existing or prospective purchasers, lessees and/or mortgagees,
to make any alterations, improvements and/or repairs, or for any other purpose
relating to the operation and/or maintenance of the Premises and/or Building.
Unless it would otherwise be impractical because of any emergency, LESSOR shall
give LESSEE at least twenty-four (24) hours notice of LESSOR'S intention to
enter the Premises and LESSOR shall use reasonable efforts to avoid interfering
with LESSEE.

     22.  SIGNS.
          -----

     22.1. Subject to LESSOR'S approval and consent, LESSEE may install, at 
LESSEE'S expense, interior and exterior signs on the Premises.  All signs shall 
conform to all rules, regulations and ordinances governing signs and shall be 
only as approved by LESSOR.  At the termination of this Lease, LESSEE shall 
remove all such signs and shall repair any damages resulting from the 
installation and/or removal of such signs, at LESSEE'S expense.

     22.2. Subject to space availability, LESSEE may place a sign advertising 
its business on any pole, marquee or other directory type sign which LESSOR may 
install and/or maintain for the Building.  LESSEE'S sign shall conform to all 
applicable rules, regulations, and ordinances and shall be at LESSEE's expense 
LESSEE shall also pay its Proportionate Share of the cost of installing and/or 
maintaining said directory sign.  Such costs shall be billed by LESSOR to LESSEE
from time to time and shall not exceed a sum determined by dividing the total 
cost of LESSOR by the number of occupants' signs included on the directory.  
LESSEE shall pay such costs as Additional Rent.

     23.  SUBORDINATION.  This Lease is subject and subordinate to all 
          -------------
mortgages, deeds of trust, or other debt instruments which may now or hereafter 
affect such lease, the Building, site or other improvements thereon.  The 
foregoing provisions shall be self operative and no further instrument of 
subordination shall be required by any mortgagee or other interested party, 
provided, however, that in confirmation of such subordination LESSEE shall, upon
request of LESSOR, executed and deliver, in recordable form, any instrument or 
subordination required by LESSOR, and LESSEE hereby does constitute and appoint 
LESSOR as LESSEE'S attorney-in-fact to execute any such subordination instrument
on behalf of LESSEE.

this Lease shall be deemed in default if LESSEE shall discontinue the business 
referred to in Paragraph 4 herein, the Premises shall become or appear vacant, 
or LESSEE abandons or appears to abandon the Premises.  Under any of the 
aforesaid conditions the LESSOR may exercise its rights as stated in Paragraph 
18 herein.

     25.  NO PARTNERSHIP.  By execution of this Lease, LESSOR does not in any 
          --------------
way become for any purpose a partner, principal, master, agent, servant, and/or

does LESSOR assume, nor become subject to any responsibility or liability 
therefore and LESSEE agrees to indemnify and hold LESSOR harmless against any
and all claims or demands, of whatever nature, arising out of the operation and
conduct of LESSEE'S business.

     26.  NOTICES.  Any notice required or permitted hereunder shall be in

flammable material.  No bird, fish or other animal shall be brought into or kept

     7.   If the LESSEE desires to install communication, data, security or

company vehicles shall not be parked in the parking spaces which are adjacent to
the front of the building.

               (a)     Revolving Loans.  (i)  Each Bank severally agrees, on the
                       ---------------                                          
     terms and conditions hereinafter set forth, to make revolving loans (each a
     "Revolving Loan" and, collectively, the "Revolving Loans") to the Companies
     jointly and severally, from time to time on any Business Day during the
     period from the date hereof until the Revolving Credit Maturity Date, in an
     aggregate principal amount up to but not exceeding at any time such Bank's
     Revolving Credit Commitment. The aggregate amount of the Revolving Credit
     Commitment is $25,800,000 as of the Second Amendment Date. Within the
     limits of each Bank's Revolving Credit Commitment, during the period up to
     the Revolving Credit Maturity Date, the Companies jointly and severally,
     may borrow, repay the Loans in whole or in part, and, subject to Section
                                                                      -------
     7.2, reborrow hereunder, all in accordance with the conditions hereof.

               (ii)    Aggregate outstanding borrowings under 
     Section 2.1(a)(i), up to the maximum principal amount equal to the
     ----------------- 
     Revolving Loan Commitment, shall not at any time exceed the Borrowing Base.
     For purposes of this Agreement, "Borrowing Base," as of any date of
     determination, shall mean the sum of:

                         (x)   eighty percent (80%) of Eligible Accounts; plus
                                                                          ----

                         (y)   the lesser of: (1) thirty-five percent (35%) of
     Eligible Inventory; and (2) Ten Million Dollars ($10,000,000); minus
                                                                    -----
                                                           
                         (z)   the aggregate amount of reserves, if any,
     established by the Agent under Section 2.1(a)(iii).
                                    -------------------
                

               (iii)  The individual components of the Borrowing Base and the
     advance rates in respect thereof shall be determined by the Agent upon
     receipt and review of the collateral reports required hereunder and such
 

                                      11
<PAGE>
 
     other documents and collateral information as the Agent may from time to
     time require. The Companies acknowledge that the Borrowing Base was
     established by the Agent with the understanding that, among other things,
     the aggregate of all returns, rebates, discounts, credits, and allowances
     for the immediately preceding three (3) months at all times shall be less
     than five percent (5%) of the Companies' gross sales for said period. If
     such dilution of the Accounts for the immediately preceding three (3)
     months at any time exceeds 5% of the Companies' gross sales for said
     period, or if there at any time exists any other matters, events,
     conditions, or contingencies that the Agent reasonably believes may affect
     the payment of any portion of the Accounts, the Agent, in its sole
     discretion, may reduce the advance rate in respect of Eligible Accounts to
     a percentage appropriate to reflect such additional dilution and/or
     establish additional reserves against the Eligible Accounts. Anything to
     the contrary herein notwithstanding, the Agent may create reserves against
     and/or reduce its advance rates based upon Eligible Accounts or Eligible
     Inventory without declaring an Event of Default if it determines, in its
     reasonable discretion, that there is a material impairment of the prospect
     of repayment of all or any portion of the Indebtedness or other obligations
     of the Companies owing to the Banks or a material impairment of the value
     or priority of the Agent's Liens on the Collateral.

in its entirety and the following hereby is substituted in lieu thereof:

     Each commercial Letter of Credit shall be issued for a term not to exceed

     outstanding that has a stated expiration date later than the Revolving
     Credit Maturity Date then in effect, the Companies shall provide to the
     Agent, on or before the Revolving Credit Maturity Date, for any such Letter
     of Credit either cash collateral or a letter of credit payment guarantee in
     form and substance and issued by a Person acceptable to the Agent, in each
     case in an amount acceptable to the Agent.

     Companies agree to assemble the Collateral consisting of personal property
     ("Personal Property Collateral") if the Agent so requires, and to make the
     Personal Property Collateral available to the Agent as the Agent may
     designate. The Companies authorize the Agent to enter the premises where
     the Personal Property Collateral is located, to take and maintain
     possession of the Personal Property Collateral, or any part of it, and to
     pay, purchase, contest, or compromise any encumbrance, charge, or lien that
     in the Agent's determination appears to conflict with its Lien and to pay
     all expenses incurred in connection therewith. With respect to any of the
     Companies' owned premises, the Companies hereby grant the Agent a license
     to enter into possession of such premises and to occupy the same, without
     charge, in order to exercise any of the Agent's rights or remedies provided
     in the Loan Documents, at law, in equity, or otherwise.

in the Loan Documents to the "Credit Agreement," "thereunder," "therein,"

in the Credit Agreement or the other Loan Documents to any of Schedule 9.14,
                                                              -------------

                e.      This Amendment may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument and any of the parties hereto may execute this Amendment by signing
any such counterpart.
                
          7.    Certain Waivers.  As used in this Section 7, the term "Bank
                ---------------                                            
Group" shall mean, individually and collectively, the Agent and the Banks.  To
the extent that any Company is a guarantor or accommodation party on behalf of
any one or more other Companies (it being understood and intended by the parties
that the Companies are joint and several obligors), the provisions of this
Section 7 shall apply:

                a.    To the maximum extent permitted by law, each Company
hereby waives: (i) notice of acceptance hereof; (ii) notice of any loans or
other financial accommodations made or extended under the Loan Documents, or the
creation or existence of any obligations thereunder (the "Obligations"); (iii)
notice of the amount of the Obligations, subject, however, to such Company's
right to make inquiry of the Agent or a Bank to ascertain the amount of the
Obligations at any reasonable time; (iv) notice of any adverse change in the
financial condition of any other Company or of any other fact that might
increase such Company's risk hereunder; and (v) notice of presentment for
payment, demand, protest, and notice thereof as to any instrument among the Loan
Documents.

                                       25
<PAGE>
 
                b.     To the fullest extent permitted by applicable law, each
Company waives the right by statute or otherwise to require the Bank Group to
institute suit against any other Company or to exhaust any rights and remedies
which the Bank Group has or may have against such other Company.  Each Company
further waives any defense arising by reason of any disability or other defense
(other than the defense that the Obligations shall have been fully and finally
indefeasibly paid) of the other Companies or by reason of the cessation from any
cause (other than that the Obligations shall have been fully and finally
indefeasibly paid) whatsoever of the liability of the other Companies in respect
thereof.

                c.      To the maximum extent permitted by law, each Company
hereby waives: (i) any rights to assert against the Bank Group any defense
(legal or equitable), set-off, counterclaim, or claim which such Company may now
or at any time hereafter have against the other Companies or any other party
liable to the Bank Group on account of or with respect to the Obligations; (ii)
any defense, set-off, counterclaim, or claim, of any kind or nature, arising
directly or indirectly from the present or future sufficiency, validity, or
enforceability of the Obligations; (iii) any defense arising by reason of any
claim or defense based upon an election of remedies by the Bank Group including,
to the extent applicable, the provisions of (S)(S) 580d and 726 of the
California Code of Civil Procedure, or any similar law of California or any
other jurisdiction; (iv) the benefit of any statute of limitations affecting
such Company's liability hereunder or the enforcement thereof.

                d.      To the maximum extent permitted by law, each Company
hereby waives and postpones until indefeasible payment in full of the
Obligations any right of subrogation such Company has or may have as against the
other Companies with respect to the Obligations. In addition, each Company
hereby waives and postpones until indefeasible payment in full of the
Obligations any right to proceed against the other Companies, now or hereafter,
for contribution, indemnity, reimbursement, or any other suretyship rights and
claims (irrespective of whether direct or indirect, liquidated or contingent),
with respect to the Obligations. Each Company also hereby waives and postpones
until indefeasible payment in full of the Obligations any right to proceed or to
seek recourse against or with respect to any property or asset of the other
Companies. Each Company hereby agrees that, in light of the waiver and
postponements of rights contained in this Section, such Company shall not be
deemed to be a "creditor" (as that term is defined in the Bankruptcy Code or
otherwise) of the other Companies, whether for purposes of the application of
Sections 547 or 550 of the Bankruptcy Code or otherwise.

                e.      If any of the Obligations at any time are secured by a
mortgage or deed of trust upon real property, the Bank Group may elect, in its
sole discretion, upon a default with respect to the Obligations, to foreclose
such mortgage or deed of trust judicially or nonjudicially in any manner
permitted by law, before or after enforcing this Agreement or any
other Loan Document, without diminishing or affecting the liability of 

                                       26
<PAGE>
 
any Company hereunder. Each Company understands that (a) by virtue of the
operation of California's antideficiency law applicable to nonjudicial
foreclosures, an election by the Bank Group nonjudicially to foreclose such a
mortgage or deed of trust probably would have the effect of impairing or
destroying rights of subrogation, reimbursement, contribution, or indemnity of
such Company against the other Companies or guarantors or sureties, and (b)
absent the waiver and postponement of rights given by each Company herein, such
an election might estop the Bank Group from enforcing this Agreement or the
other Loan Documents against such Company. Understanding the foregoing, and
understanding that each Company is hereby relinquishing a defense to the
enforceability of this Agreement and the other Loan Documents, each Company
hereby waives any right to assert against the Bank Group any defense to the
enforcement of this Agreement and the other Loan Documents, whether denominated
"estoppel" or otherwise, based on or arising from an election by the Bank Group
nonjudicially to foreclose any such mortgage or deed of trust. Each Company
understands that the effect of the foregoing waiver may be that such Company may
have liability hereunder for amounts with respect to which such Company may be
left without rights of subrogation, reimbursement, contribution, or indemnity
against the other Companies or guarantors or sureties. Each Company also agrees
that the "fair market value" provisions of Section 580a of the California Code
of Civil Procedure shall have no applicability with respect to the determination
of such Company's liability under this Agreement or the other Loan Documents.

                f.      WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR
OTHER PROVISION SET FORTH IN THIS AGREEMENT, EACH COMPANY HEREBY WAIVES, TO THE
MAXIMUM EXTENT SUCH WAIVER IS PERMITTED BY LAW, ANY AND ALL DEFENSES ARISING
DIRECTLY OR INDIRECTLY UNDER ANY ONE OR MORE OF CALIFORNIA CIVIL CODE (S)(S)
2808, 2809, 2810, 2815, 2819, 2820, 2821, 2838, 2839, 2845, 2848, 2849, AND
2850, TO THE EXTENT APPLICABLE, CALIFORNIA CODE OF CIVIL PROCEDURE (S)(S) 580a,
580b, 580c, 580d, AND 726, AND, TO THE EXTENT APPLICABLE, CHAPTER 2 OF TITLE 14
OF THE CALIFORNIA CIVIL CODE.

                g.      WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR
OTHER PROVISION SET FORTH IN THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, EACH
COMPANY HEREBY WAIVES ALL RIGHTS AND DEFENSES ARISING OUT OF AN ELECTION OF
REMEDIES BY THE BANK GROUP, EVEN THOUGH THAT ELECTION OF REMEDIES, SUCH AS A
NONJUDICIAL FORECLOSURE WITH RESPECT TO SECURITY FOR AN OBLIGATION, HAS
DESTROYED SUCH COMPANY'S RIGHTS OF SUBROGATION AND REIMBURSEMENT AGAINST THE
PRINCIPAL BY THE OPERATION OF SECTION 580d OF THE CODE OF CIVIL PROCEDURE OR
OTHERWISE.

                     Reaffirmation and Consent of Guarantor


          All capitalized terms used herein but not otherwise defined herein
shall have the meanings ascribed to them in that certain Amendment to Credit
Agreement, dated as of February 15, 1996 (the "Amendment").

          Each of the undersigned hereby agrees that each reference in the Loan
Documents to the "Credit Agreement," "thereunder," "therein," "thereof" or words
of like import referring to the Credit Agreement shall mean and refer to the
Credit Agreement as amended by the Amendment.

          Each of the undersigned hereby (a) represents and warrants to the
Agent and the Banks that the execution, delivery, and performance of this
Reaffirmation and Consent of Guarantor and the other Loan Documents required by
the Amendment to be executed and delivered by it are within its corporate
powers, have been duly authorized by all necessary corporate action, and, except
for such instances that could not reasonably be expected to have a Material
Adverse Effect, are not in contravention of any law, rule, or regulation, or any
order, judgment, decree, writ, injunction, or award of any arbitrator, court, or
governmental authority, or of the terms of its charter or bylaws, or of any
contract or undertaking to which it is a party or by which any of its properties
may be bound or affected; (b) consents to the amendment of the Credit Agreement
by the Amendment; (c) acknowledges and reaffirms its obligations owing to the

is a party; and (d) agrees that its guaranty and any such other Loan Documents
are and shall remain in full force and effect.  Although each of the undersigned
has been informed of the matters set forth herein and has acknowledged and
agreed to same, it understands that the Agent and the Banks have no obligation
to inform it of such matters in the future or to seek its acknowledgement or
agreement to future amendments, and nothing herein shall create such a duty.
Each of the undersigned also hereby agrees to execute and deliver all
agreements, documents, and instruments, in form and substance satisfactory to
the Agent, and take all

                                      S-4

          1.  Payment of Debt.  The Mortgagor will pay the Debt at the time and
              ---------------                                                  
in the manner provided for its payment in the Credit Agreement, the Notes and in
this Mortgage.

          2.  Warranty of Title; Other Representations and Warranties.
              -------------------------------------------- ---------- 

              (a) Except as disclosed on Schedule I(2)(a) hereto, the Mortgagor
warrants the title to the Premises, the Improvements, the Equipment and the
balance of the Mortgaged Property.

              (b) The Mortgagor also represents and warrants that:  (i) the
Mortgagor is now, and after giving effect to this Mortgage, will be in a solvent
condition, (ii) the execution and delivery of this Mortgage by the Mortgagor
does not constitute a fraudulent conveyance, within the meaning of Title 11 of
the United States Code as now constituted or under any other applicable statute,
(iii) no bankruptcy or insolvency proceedings are pending or contemplated by or
against the Mortgagor, and (iv) there are no existing, pending or, to the best
knowledge of Mortgagor, threatened actions or proceedings which are reasonably
expected to materially adversely affect the Mortgaged Property

                                       3
<PAGE>
 
except for possible negligence actions or proceedings which are fully covered by
insurance.

              (c) The Mortgagor additionally represents and warrants that: (i)
it has full corporate power and authority to execute this Mortgage, and to
mortgage, give, grant, bargain, sell, alien, enfeoff, convey, confirm and assign
the Mortgaged Property pursuant to the terms hereof and to keep and observe all
of the terms of this Mortgage on the Mortgagor's part to be performed, and (ii)
the Mortgagor is a duly organized and presently existing corporation and the
execution and delivery of this Mortgage has been duly authorized by all
necessary corporate action on behalf of the Mortgagor.

          3.  Insurance.
              --------- 

              (a) The Mortgagor, at its expense, (i) will keep the Improvements
and the Equipment insured with extended coverage against loss or damage by fire,
vandalism, malicious mischief and such other hazards as the Mortgagee shall from
time to time require, in amounts approved by the Mortgagee, which amounts shall
in no event be less than one hundred percent (100%) of the full insurable value
of the Improvements and the Equipment and shall be sufficient to meet all
applicable co-insurance requirements, and (ii) will maintain rental and business
interruption insurance and such other forms of insurance coverage with respect
to the Mortgaged Property as the Mortgagee shall from time to time require in
amounts approved by the Mortgagee. If any portion of the Premises is located in
a Federally designated special flood hazard area, in addition to the other
policies of insurance required under this paragraph (the "Policies"), a flood
insurance policy shall be delivered by the Mortgagor to the Mortgagee. If no
portion of the Premises is located in a Federally designated "special flood
hazard area", such fact shall be substantiated by a certificate in form
satisfactory to the Mortgagee from a licensed surveyor, appraiser or
professional engineer or other qualified person satisfactory to the Mortgagee in
accordance with applicable regulations.

              (b) The Mortgagor shall at all times comply with and shall cause
the Improvements and Equipment and the use, occupancy, operation, maintenance,
alteration, repair and restoration thereof to comply with the terms, conditions,
stipulations and requirements of the Policies. All Policies shall be issued by
insurers having a minimum policy holders rating of "A1" per the latest rating
publication of Property and Casualty Insurers by A.M. Best Company and who are
lawfully doing business in New York and are otherwise acceptable in all respects
to the Mortgagee. All Policies shall, with respect to the Premises and the
Improvements, contain the standard New York mortgagee non-contribution clause
endorsement or an equivalent endorsement and, with respect to the Equipment,
contain a lender's loss payable clause endorsement or an equivalent

                                       4
<PAGE>
 
endorsement, all naming the Mortgagee as the person to which all payments made
by the insurer thereunder shall be paid and otherwise in form and substance
satisfactory in all respects to the Mortgagee.  Blanket insurance policies shall
not be acceptable for the purposes of this paragraph unless otherwise approved
to the contrary by the Mortgagee.  The Mortgagor shall pay the premiums for the
Policies as the same become due and payable.  At the request of the Mortgagee,
the Mortgagor will deliver the Policies to the Mortgagee.  Not later than thirty
(30) days prior to the expiration date of each of the Policies, the Mortgagor
will deliver to the Mortgagee a renewal policy or policies marked "premium paid"
or accompanied by other evidence of payment of premium satisfactory to the
Mortgagee.  If at any time the Mortgagee is not in receipt of written evidence
that all insurance required hereunder is in full force and effect, the Mortgagee
shall have the right, but not the obligation, without notice to the Mortgagor,
to take such action as the Mortgagee deems necessary to protect its interest in
the Mortgaged Property, including, without limitation, the obtaining of such
insurance coverage as the Mortgagee in its sole discretion deems appropriate,
and all expenses incurred by the Mortgagee in connection with such action or in
obtaining such insurance and keeping it in effect shall be paid by the Mortgagor
to the Mortgagee upon demand and until paid shall be secured by this Mortgage in
accordance with Paragraph 7 of Article II hereof.

              (c) If the Mortgaged Property shall be damaged or destroyed, in
whole or in part, by fire or other property hazard or casualty, the Mortgagor
shall give prompt notice thereof to the Mortgagee. Proceeds paid to the
Mortgagee by any insurer may be retained and applied by the Mortgagee toward
payment of the Debt, whether or not then due and payable, in such order,
priority and proportions as the Mortgagee in its discretion shall deem proper
or, at the discretion of the Mortgagee, the same may be paid, either in whole or
in part, to the Mortgagor for such purposes as the Mortgagee shall reasonably
designate.

              (d) Notwithstanding the foregoing, in the event such proceeds with
respect to any particular insured loss are less than $1,500,000 and the
Mortgagee determines, reasonably and in good faith, that there has been no
material impairment of the prosect of repayment of any portion of the Debt or
any material impairment of the value of the Mortgagee's security interests in
the collateral securing the Debt, the Mortgagee shall deliver such proceeds to
the Mortgagor, for the purpose of repair or restoration of the damaged property
or, at the request of the Mortgagor, shall apply such proceeds to the repayment
of the Term Loan Notes. In the event such proceeds with respect to any
particular insured loss are equal to or greater than $1,500,000, the Mortgagee,
in its reasonable judgment, may elect to either apply such proceeds on account
of any portion of the Debt (initially with respect to the Term Loan Notes then
outstanding and, thereafter, to the Revolving Loans (as defined in the Credit

                                       5
<PAGE>
 
Agreement) then outstanding) or deliver all or a portion of such proceeds to the
Mortgagor for the purpose of repair or restoration of the damaged property.

              (e) If the Mortgagee shall receive and retain such insurance
proceeds, the lien of this Mortgage shall be reduced only by the amount thereof
received and retained by the Mortgagee and actually applied by the Mortgagee in
reduction of the debt. The Mortgagee shall not be obligated to see to the proper
application of insurance money paid over to the Mortgagor, and if the Mortgagee
receives and retains any insurance proceeds, the lien of this Mortgage shall be
affected only by a reduction of the amount of said lien by the amount of such
insurance money so received and retained by the Mortgagee. Nevertheless, if
prior to the receipt by the Mortgagee of any insurance proceeds, the Premises
shall have been sold on foreclosure of this Mortgage, as between the Mortgagor
and the Mortgagee, the Mortgagee shall have the right to receive said insurance
proceeds, and the Mortgagor shall pay over to the Mortgagee said insurance
proceeds as, if and when the Mortgagor receives same, to the extent of (i) any
deficiency found to be due upon such sale, with legal interest thereon, whether
or not a deficiency judgment on this Mortgage shall have been sought or
recovered, and (ii) of the attorney's fees, costs and disbursements incurred by
the Mortgagee in connection with the collection of such insurance proceeds. All
remaining right, title and interest of the Mortgagor in and to all policies of
insurance required by this Paragraph 3 shall inure to the benefit of and pass to
the successor in-interest to the Mortgagor or the purchaser or grantee of the
Mortgaged Property. The Mortgagor hereby appoints the Mortgagee its attorney-in-
fact to endorse any checks, drafts or other instruments representing any
proceeds of such insurance, whether payable by reason of loss thereunder or
otherwise. The provisions of subsection 4 of Section 254 of the Real Property
Law of New York covering the insurance of buildings against loss by fire shall
not apply to this Mortgage.

          4.  Payment of Taxes, etc.  The Mortgagor shall pay all taxes,
              ---------------------                                     
assessments, water rates, sewer rents and other charges, including vault charges
and license fees for the use of vaults, chutes and similar areas adjoining the
Premises, now or hereafter levied or assessed against the Mortgaged Property by
any public or quasi-public authority or utility company (collectively, the
"Taxes") prior to the date upon which any fine, penalty, interest or cost may be
added thereto or imposed by law for the nonpayment thereof, and, in default
thereof, the Mortgagee may, in its sole discretion, but shall not be obligated
to, pay same (all such payments to be secured hereby in accordance with
Paragraph 7 of Article II hereof), and the Mortgagor shall reimburse the
Mortgagee promptly following demand for such expenditures.

                                       6
<PAGE>
 
          5.  Escrow Fund. After an Event of Default has occurred, and during
              -----------                                                    
the continuation thereof, the Mortgagor will, at the option of and following
written notice by the Mortgagee, pay to the Mortgagee on the first day of each
calendar month one-twelfth of an amount (the "Escrow Fund") which would be
sufficient to pay, on the first day of the month preceding the month in which
they become due, the Taxes and the premiums on all Policies (the "Premiums")
payable, or estimated by the Mortgagee to be payable, during the ensuing twelve
(12) months.  The Mortgagee will apply the Escrow Fund to the payment of Taxes
and the Premiums which are required to be paid by the Mortgagor pursuant to the
provisions of this Mortgage.  If the amount of the Escrow Fund shall exceed the
amount of the Taxes and the Premiums payable by the Mortgagor pursuant to the
provisions of this Mortgage, the Mortgagee shall, in its discretion, (i) return
any excess to the Mortgagor, or (ii) credit such excess against future payments
to be made to the Escrow Fund.  In allocating such excess, the Mortgagee may
deal with the person shown on the records of the Mortgagee to be the owner of
the Mortgaged Property.  If the amount being deposited on a monthly basis into
the Escrow Fund is not sufficient to pay the Taxes and/or the Premiums, as the
same become payable, the Mortgagor shall pay to the Mortgagee, upon request, an
amount which the Mortgagee shall estimate as sufficient to make up the
deficiency.  Until expended or applied as above provided, any amounts in the
Escrow Fund shall be held in a security account and shall constitute additional
security for the Debt and shall not bear interest except to the extent and in
the amount required by law.

          6.  Condemnation.  Notwithstanding any taking by any public or quasi-
              ------------                                                    
public authority through eminent domain or otherwise, the Mortgagor shall
continue to pay the Debt at the time and in the manner provided for its payment
in the Notes and this Mortgage and the Debt shall not be reduced until any award
or payment therefore shall have been actually received and applied by the
Mortgagee to the discharge of the Debt.  If an Event of Default has occurred or
is then continuing, or if the Mortgagee otherwise has reasonably determined that
its security is or may be impaired, then the Mortgagee may apply the entire
amount of any such award or payment to the discharge of the Debt whether or not
then due and payable in such order, priority and proportions as the Mortgagee in
its discretion shall deem proper.  If an Event of Default is not then
continuing, or if the Mortgagee's security is not then impaired, then such award
or proceeds shall be released to Mortgagor upon such conditions as the Mortgagee
reasonably may impose.  The Mortgagee shall not be obligated to see to the
proper application of any award or payment paid over to the Mortgagor, and if
the Mortgagee receives such award or payment, the lien of this Mortgage shall be
affected only by a reduction of the amount of said lien by the amount of such
award or payment so received by the Mortgagee.  If the Mortgaged Property is
sold, through foreclosure or otherwise, prior to the receipt by the Mortgagee of
such award or payment,

                                       7
<PAGE>
 
the Mortgagee shall have the right, whether or not a deficiency judgment on the
Notes shall have been sought, recovered or denied, to receive such award or
payment, or a portion thereof sufficient to pay the Debt, whichever is less, and
the Mortgagor shall pay over to the Mortgagee said award or payment as, if and
when the Mortgagor receives same, to the extent of any deficiency judgment found
to be done upon such sale, with interest thereon, whether or not a deficiency
judgment on this Mortgage shall have been sought or recovered or denied, and of
the attorney's fees, costs and disbursements incurred by the Mortgagee in
connection with the collection of such award or payment.  It is the express
intent and agreement of the parties that in the event of any such taking, the
Mortgagee shall receive interest at the rate set forth in the Notes (the "Note
Rate") up to and including the date of actual payment in full of the Debt,
provided that the rate set forth in the Notes is higher than the statutory rate,
and the Mortgagor (or any assignee or successor in interest thereof) shall
therefore be responsible to pay to the Mortgagee an amount equal to the entire
difference between the amount of interest received by the Mortgagee from the
condemning authority (or to which the Mortgagee is entitled under the
condemnation interest statute) and the Note Rate from the date of vesting of
title in such condemnation to the date of actual payment, except where the
statutory rate on the condemnation award is higher than the Note Rate, in which
event, the Mortgagee shall be entitled to the statutory rate.  The Mortgagor
shall file and prosecute its claim or claims for any such award or payment in
good faith and with due diligence and cause the same to be collected and paid
over to the Mortgagee.  The Mortgagor hereby irrevocably authorizes and empowers
the Mortgagee, in the name of the Mortgagor or otherwise, to collect and receipt
for any such award or payment and to file and prosecute such claim or claims.
Although it is hereby expressly agreed that the same shall not be necessary in
any event, the Mortgagor shall, upon demand of the Mortgagee, make, execute and
deliver any and all assignments and other instruments sufficient for the purpose
of assigning any such award or payment to the Mortgagee, free and clear of any
encumbrances of any kind or nature whatsoever.

          7.  Leases and Rents.  Subject to the terms of this paragraph, the
              ----------------                                              
Mortgagee waives the right to enter the Mortgaged Property for the purpose of
collecting the Rents, and grants the Mortgagor the right to collect the Rents
and to let the Mortgaged Property or any part thereof.  The Mortgagor shall hold
the Rents in trust for use in payment of the Debt.  The right of the Mortgagor
to collect the Rents and to let the Mortgaged Property or any part thereof may
be revoked by the Mortgagee upon and during the continuance of any Event of
Default by the Mortgagor under the terms of the Notes or this Mortgage and for
the duration thereof, the Mortgagee may let the Mortgaged Property or any part
thereof and may retain and apply the Rents toward payment of the Debt in such
order, priority and proportions as the Mortgagee, in its reasonable discretion,
shall deem proper,

                                       8
<PAGE>
 
or toward the operation, maintenance and repair of the Mortgaged Property, and
irrespective of whether the Mortgagee shall have commenced a foreclosure of this
Mortgage or shall have applied or arranged for the appointment of a receiver.
The Mortgagee shall give to the Mortgagor notice of such revocation of the right
to let and collect the Rents within a reasonable time thereafter.  The Mortgagor
shall not, without the consent of the Mortgagee, make, or suffer to be made, any
Leases or modify any Leases or cancel any Leases or accept prepayments of
installments of the Rents for a period of more than one (1) month in advance or
further assign the whole or any part of the Rents.  The Mortgagee shall have all
of the rights against tenants of the Mortgaged Property as set forth in Section
291-f of the Real Property Law of New York.  The Mortgagor shall (i) fulfill or
perform each and every provision of the Leases on the part of the Mortgagor to
be fulfilled or performed, (ii) promptly send copies of all notices of default
which the Mortgagor shall send or receive under the Leases to the Mortgagee, and
(iii) enforce, short of termination of the Leases, the performance or observance
of the provisions thereof by the tenants thereunder.  Nothing contained in this
paragraph shall be construed as imposing on the mortgagee any of the obligations
of the lessor under the Leases.

          8.   Transfer or Encumbrance of the Mortgaged Property.  Except as may
               -------------------------------------------------                
be permitted in the Credit Agreement, no part of the Mortgaged Property nor any
interest of any nature whatsoever therein, nor any interest of any nature
whatsoever in the Mortgagor (whether partnership, stock, equity, beneficial,
membership, profit, loss or otherwise) shall in any manner be further
encumbered, sold, transferred, assigned or conveyed, or permitted to be further
encumbered, sold, transferred, assigned or conveyed without the prior written
consent of the Mortgagee, which consent in any and all circumstances may be
withheld in the sole and absolute discretion of the Mortgagee.  The provisions
of the foregoing sentence of this paragraph shall apply to each and every such
further encumbrance, sale, transfer, assignment or conveyance, regardless of
whether or not the Mortgagee has consented to, or waived by its action or
inaction its rights hereunder with respect to, any such previous further
encumbrance, sale, transfer, assignment or conveyance, and irrespective of
whether such further encumbrance, sale, transfer, assignment or conveyance is
voluntary, by reason of operation of law or is otherwise made.

          9.  Maintenance of the Mortgaged Property; Compliance with Laws,
              ------------------------------------------------- ----------
Regulations, Covenants and Easements.
- - ------------------------------------ 

          (a) The Mortgagor shall cause the Mortgaged Property to be maintained
in good condition and repair and, to the extent of any renovations that are made
by the Mortgagor, the same shall be made in compliance with the requirements of
all governmental authorities having jurisdiction over the Mortgaged Property.
The Mortgagor will not commit or suffer to be

                                       9
<PAGE>
 
committed any waste of the Mortgaged Property.  The Improvements and the
Equipment shall not be removed, demolished or materially altered (except for
normal replacement of the Equipment in the ordinary course of the Mortgagor's
business), without the consent of the Mortgagee, which consent shall not be
unreasonably withheld.  The Mortgagor shall promptly repair, replace or rebuild
any part of the Mortgaged Property which may be damaged or destroyed by fire or
other property hazard or casualty (including any fire or other property hazard
or casualty for which insurance was not obtained or obtainable) or which may be
affected by any taking by any public or quasi-public authority through eminent
domain or otherwise, and shall complete and pay for, within a reasonable time,
any structure at any time in the process of construction or repair on the
Premises.

              (b) The Mortgagor represents and warrants that, except to the
extent set forth on Schedule I(9)(b) hereto, the Mortgaged Property is currently
and in all material respects in compliance with, and the Mortgagor shall in the
future promptly comply in all material respects with, all existing and future
governmental laws, orders, ordinances, rules and regulations affecting the
Mortgaged Property, or any portion thereof or the use thereof, including
specifically, but not by way of limitation, all provisions of the Americans with
Disabilities Act. The Mortgagor shall comply in all material respects with the
requirements of all, and shall not materially modify, amend or terminate any,
easements and restrictive covenants which from time to time materially affect
the whole or any portion of the Mortgaged Property. The Mortgagor shall also
comply in all material respects with the requirements of, and to the extent
reasonably within the Mortgagor's control, maintain, preserve, enforce and
renew, all rights of way, easements, grants, privileges, licenses, franchises
and restrictive covenants which from time to time benefit or pertain in any
material respect to the whole or any portion of the Mortgaged Property, and the
Mortgagor shall not materially modify, amend or terminate, or surrender any of
its rights under, any of such rights of way, easements, grants, privileges,
licenses, franchises or restrictive covenants. The Mortgagor will not, without
obtaining the prior written consent of the Mortgagee, initiate, join in or
consent to any new private restrictive covenant, zoning ordinance, or other
public or private restrictions, limiting or affecting the uses which may be made
of the Mortgaged Property or any part thereof. Except as may be done in the
ordinary course of the Mortgagor's business, the Mortgagor will not materially
alter the use of the Mortgaged Property without the prior written consent of the
Mortgagee.

          10. Environmental Provisions.
              ------------------------ 

              (a) For the purposes of this paragraph, the term "Hazardous
Material" shall mean any material or substance that, whether by its nature or
use, is now or hereafter defined as a

                                       10
<PAGE>
 
hazardous waste, hazardous substance, pollutant or contaminant under any
Environmental Requirement (as defined in paragraph (b) below), or which is
toxic, explosive, corrosive, flammable, infectious, radioactive, carcinogenic,
mutagenic or otherwise hazardous or which is or contains petroleum, gasoline,
diesel fuel or another petroleum hydrocarbon product.

              (b) The Mortgagor hereby represents and warrants to the Mortgagee
that, except as disclosed to and acknowledged by the Mortgagee in writing prior
to the date hereof: (i) during the period of the Mortgagor's ownership or
possession of the Premises, there has been no use, generation, manufacture,
storage, treatment, disposal, release or threatened release of any hazardous
waste or hazardous substance (as said terms are defined in the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended, the
Superfund Amendments and Reauthorization Act of 1986, any other applicable state
or Federal environmental laws, and any rules or regulations, all as adopted or
as may be adopted pursuant to any of the foregoing) (collectively,
"Environmental Requirements") by any person from, on, under or about the
Premises; and (ii) the Mortgagor has no knowledge of, nor any reason to believe
that there has been (a) any use, generation, manufacture, storage, treatment,
disposal, release or threatened release of any hazardous waste or hazardous
substance by any prior owners or occupants of the Premises, or (b) any actual or
threatened litigation or claims of any kind by any person relating to such
matters.  The Mortgagor agrees to indemnify and hold the Mortgagee harmless from
and against any and all claims, losses, liabilities, damages, penalties and
expenses of any kind or character, including reasonable attorneys' fees, which
the Mortgagee may directly or indirectly sustain of suffer as a result of any
breach of this Section 10, or as a consequence of any use, generation,
manufacture, storage, treatment, disposal, release or threatened release
occurring prior to the Mortgagor's ownership of any interest in the Premises,
whether or not the same was or should have been known to the Mortgagor.

              (c) The Mortgagor shall comply, and shall cause all tenants or
other occupants of the Mortgaged Property to comply, in all respects with all
Environmental Requirements, and will not generate, store, handle, process,
dispose of or otherwise use, and will not permit any tenant or other occupant of
the Mortgaged Property to generate, store, handle, process, dispose of or
otherwise use, Hazardous Materials at, in, on, or about the Mortgaged Property
in a manner that could lead or potentially lead to the imposition on the
Mortgagor, the Mortgagee or the Mortgaged Property of any liability or lien of
any nature whatsoever under any Environmental Requirement. The Mortgagor shall
notify the Mortgagee promptly in the event of any spill or other release of any
Hazardous Material at, in, on, under or about the Mortgaged Property which is
required to be reported to any governmental authority under any Environmental

                                       11
<PAGE>
 
Requirement, will promptly forward to the Mortgagee copies of any notices
received by the Mortgagor relating to alleged violations of any Environmental
Requirement and will promptly pay when due any fine or assessment against the
Mortgagee, the Mortgagor or the Mortgaged Property relating to any Environmental
Requirement.  If at any time it is determined that the operation or use of the
Mortgaged Property violates any applicable Environmental Requirement or that
there are Hazardous Materials located at, in, on, under or about the Mortgaged
Property that violate any applicable Environmental Requirement or that there are
Hazardous Materials located at, in, on, under or about the Mortgaged Property
which, under any Environmental Requirement, require special handling in
collection, storage, treatment or disposal, or any other form of cleanup or
corrective action, the Mortgagor shall, within thirty (30) days after receipt of
notice thereof from any governmental authority or from the Mortgagee, take, at
the Mortgagor's sole cost and expense, such actions as may be necessary to fully
comply in all respects with all Environmental Requirements, provided, however,
that if such compliance cannot reasonably be completed within such thirty (30)
day period, the Mortgagor shall commence such necessary action within such
thirty (30) day period and shall thereafter diligently and expeditiously proceed
to fully comply in all respects and in a timely fashion with all Environmental
Requirements.

              (d) If the Mortgagor fails to timely take, or to diligently and
expeditiously proceed to complete in a timely fashion, any such action described
in clause (c) above, the Mortgagee may, in its sole and absolute discretion,
make advances or payments toward the performance or satisfaction the same, but
shall in no event be under any obligation to do so.  All sums so advanced or
paid by the Mortgagee (including, without limitation, counsel and consultant
fees and expenses, and fines or other penalty payments) and all sums advanced or
paid in connection with any judicial or administrative investigation or
proceeding relating thereto, will immediately, upon demand, become due and
payable from the Mortgagor and shall bear interest at the Default Rate from the
date any such sums are so advanced or paid by the Mortgagee until the date any
such sums are paid by the Mortgagor to the Mortgagee.  The Mortgagor will
execute and deliver, promptly upon request, such instruments as the Mortgagee
may deem useful or necessary to permit the Mortgagee to take any such action,
and such additional notes and mortgages, as the Mortgagee may require to secure
all sums so advanced or paid by the Mortgagee.  If a lien is filed against the
Mortgaged Property by any governmental authority resulting from the need to
expend or the actual expending of monies arising from an action or omission,
whether intentional or unintentional, of the Mortgagor or for which the
Mortgagor is responsible, resulting in the releasing, spilling, leaking,
leaching, pumping, emitting, pouring, emptying or dumping of any Hazardous
Material into the waters or onto land located within or without the State where
the Mortgaged Property is located, then the Mortgagor will, within

                                       12
<PAGE>
 
thirty (30) days from the date that the Mortgagor is first given notice that
such lien has been placed against the Mortgaged Property (or within such shorter
period of time as may be specified by the Mortgagee if such governmental
authority has commenced steps to cause the Mortgaged Property to be sold
pursuant to such lien), either (a) pay the claim and remove the lien, or (b)
furnish a cash deposit, bond, or such other security with respect thereto as is
satisfactory in all respects to the Mortgagee and is sufficient to effect a
complete discharge of such lien on the Mortgaged Property.

              (e) The Mortgagee may, at its option, at intervals of not less
than one year, or more frequently if the Mortgagee reasonably believes that a
Hazardous Material or other environmental condition violates or threatens to
violate any Environmental Requirement, cause an environmental audit of the
Mortgaged Property or portions thereof to be conducted to confirm the
Mortgagor's compliance with the provisions of this paragraph, and the Mortgagor
shall cooperate in all reasonable ways with the Mortgagee in connection with any
such audit. The Mortgagor shall bear all costs and expenses incurred in
connection with such audit.

              (f) If this Mortgage is foreclosed, or if the Mortgaged Property
is sold pursuant to the provisions of this Mortgage, or if the Mortgagor tenders
a deed or assignment in lieu of foreclosure or sale, the Mortgagor shall deliver
the Mortgaged Property to the purchaser at foreclosure or sale or to the
mortgagee, its nominee, or wholly-owned subsidiary, as the case may be, in a
condition that complies in all respects with all Environmental Requirements. The
Mortgagor will defend, indemnify, and hold harmless the Mortgagee, its
employees, agents, officers, and directors, from and against any and all claims,
demands, penalties, causes of action, fines, liabilities, settlements, damages,
costs, or expenses of whatever kind or nature, known or unknown, foreseen or
unforeseen, contingent or otherwise (including, without limitation, counsel and
consultant fees and expenses, investigation and laboratory fees and expenses,
court costs, and litigation expenses) arising out of, or in any way related to,
(i) any breach by the Mortgagor of any of the provisions of this paragraph, (ii)
the presence, disposal, spillage, discharge, emission, leakage, release, or
threatened release of any Hazardous Material which is at, in, on, under, about,
from or affecting the Mortgaged Property, including, without limitation, any
damage or injury resulting from any such Hazardous Material to or affecting the
Mortgaged Property or the soil, water, air, vegetation, buildings, personal
property, persons or animals located on the Mortgaged Property or on any other
property or otherwise, (iii) any personal injury (including wrongful death) or
property damage (real or personal) arising out of or related to any such
Hazardous Material, (iv) any lawsuit brought or threatened, settlement reached,
or order or directive of or by any governmental authority relating to such
Hazardous

                                       13
<PAGE>
 
Material, or (v) any violation of any Environmental Requirement or any policy or
requirement of the Mortgagee hereunder.  The aforesaid indemnification shall,
notwithstanding any exculpatory or other provision of any other document or
instrument now or hereafter executed and delivered in connection with the loan
evidenced by the Notes and secured by this Mortgage, constitute the personal
recourse undertakings, obligations and liabilities of the Mortgagor.

              (g) The obligations and liabilities of the Mortgagor under this
paragraph 10 shall survive and continue in full force and effect and shall not
be terminated, discharged or released, in whole or in part, irrespective of
whether the Debt has been paid in full and irrespective of any foreclosure of
this Mortgage, sale of the Mortgaged Property pursuant to the provisions of this
Mortgage or acceptance by the Mortgagee, its nominee or wholly-owned subsidiary
of a deed or assignment in lieu of foreclosure or sale and irrespective of any
other fact or circumstance of any nature whatsoever.

          11. Performance of Other Agreements.  The Mortgagor shall observe and
              -------------------------------                                  
perform each and every term to be observed or performed by the Mortgagor
pursuant to the terms of any agreement or recorded instrument affecting or
pertaining to the Mortgaged Property.

          12. Other Security for the Debt.  The Mortgagor shall observe and
              ---------------------------                                  
perform all of the terms, covenants and provisions contained in the Notes and in
all other mortgages and other instruments or documents evidencing, securing or
guaranteeing payment of the Debt, in whole or in part, or otherwise executed and
delivered in connection with the Notes, this Mortgage or the loans evidenced and
secured thereby or hereby.

          13. Right of Entry.  The Mortgagee and its agents shall have the
              --------------                                              
right to enter and inspect the Mortgaged Property at all reasonable times.

          14. New York Trust Fund.  Pursuant to Section 13 of the Lien Law of
              -------------------                                            
New York, the Mortgagor shall receive the advances secured hereby and shall hold
the right to receive the advances secured hereby as a trust fund to be applied
first for the purpose of paying the cost of any improvement and shall apply such
advances first to the payment of the cost of any such improvement on the
Mortgaged Property before using any part of the total of the same for any other
purpose.

          1. Events of Default.  The Debt shall become due at the option of the

          (d) below) or other person shall be in default under the Notes, under
          the Credit Agreement, or under any other mortgage, instrument or
          document evidencing, securing or guaranteeing payment of the Debt, in
          whole or in part, or otherwise executed and delivered in connection
          with the Notes, this Mortgage or the loans evidenced and secured
          thereby or hereby (in each case, however, after the expiration of any
          applicable cure period set forth herein or therein);

               (b) if any Federal tax lien is filed against the Mortgagor or the
          Mortgaged Property and the same is not discharged of record or
          contested in good faith (as determined by the Mortgagee in its sole
          discretion), within sixty (60) days after the same is filed;

               (c) if on application of the Mortgagee two or more fire insurance
          companies lawfully doing business in the State of New York refuse to
          issue Policies;

               (d) if any representation or warranty of the Mortgagor, or of any
          person (a "Guarantor") guaranteeing payment of the Debt or any portion
          thereof, or of operating expenses of the Mortgaged Property or
          performance by the Mortgagor of any of the terms of this Mortgage made
          herein or in any such guaranty (a "Guaranty"), or in any certificate,
          report, financial statement or other instrument furnished in
          connection with the making of the Notes, or this Mortgage or any such
          Guaranty shall prove false or misleading in any material respect;

               (e) if the Mortgagor or any Guarantor (each of whom is
          hereinafter in this subparagraph referred to as an "Obligor") shall
          commence any case, proceeding or other action relating to it in
          bankruptcy or seeking reorganization, liquidation, dissolution,
          winding-up, arrangement, composition or readjustment of its debts, or

          indicating its consent to, approval of, acquiescence in, or in
          furtherance of, any of the foregoing; or if any case, proceeding or
          other action

                                       15

          against an Obligor shall be commenced in bankruptcy or seeking
          reorganization, liquidation, dissolution, winding up, arrangement,

          arrangement, composition, readjustment of debt or other similar act or
          law of any jurisdiction, domestic or foreign, now or hereafter
          existing; or if a warrant of attachment, execution or distraint, or
          similar process, shall be issued against any substantial part of the
          property of an Obligor and such condition shall continue for a period
          of sixty (60) days undismissed, undischarged or unbonded;

               (f) if the Mortgagor or any Guarantor shall be in default (after
          the expiration of any applicable grace period) under any mortgage or
          deed of trust covering any part of the Mortgaged Property whether
          superior or inferior in lien to this Mortgage, and including, without
          limitation, any such mortgage or deed of trust now or hereafter held
          by the Mortgagee; or

               (g) if the Mortgagor shall continue to be in default under any of
          the other terms, covenants or conditions of this Mortgage for five (5)
          days after notice from the Mortgagee in the case of any default which
          can be cured by the payment of a sum of money or for thirty (30) days
          after notice from the Mortgagee in the case of any other default,
          recognizing that the cure periods set forth in this subparagraph shall
          not be in addition to those provided in the Credit Agreement, the
          Notes or elsewhere in this Mortgage.

          2.   Appointment of Receiver.  The holder of this Mortgage, in any
               -----------------------                                      
action to foreclose it, shall be entitled to the appointment of a receiver.  In
addition, upon the actual or threatened waste to any part of the Mortgaged
Property or upon the occurrence of any default hereunder, the holder of this
Mortgage shall be at liberty, without notice, to apply for the appointment of a
receiver of the Rents, and shall be entitled to the appointment of such receiver
as a matter of right, without regard to the value of the Mortgaged Property as
security for the Debt, or the solvency or insolvency of any person then liable
for the payment of the Debt.

          3.   Sale of Mortgaged Property.  If this Mortgage is foreclosed,
               --------------------------                                  
the Mortgaged Property, or any interest therein, may, at the discretion of the
Mortgagee, be sold in one or more parcels or in several interests or portions
and in any order or manner.

          4.   Security Agreement.  This Mortgage constitutes both a real
               ------------------                                        
property mortgage and a "security agreement," within

                                       16
<PAGE>
 
the meaning of the Uniform Commercial Code, and the Mortgaged Property includes
both real and personal property and all other rights and interests, whether
tangible or intangible in nature, of the Mortgagor in the Mortgaged Property.
The Mortgagor by executing and delivering this Mortgage has granted to the
Mortgagee, as security for the Debt, a security interest in the Equipment.  If
the Mortgagor shall default under the Notes or this Mortgage, the Mortgagee, in
addition to any other rights and remedies which it may have, shall have and may
exercise immediately and without demand, any and all rights and remedies granted
to a secured party upon default under the Uniform Commercial Code, including,
without limiting the generality of the foregoing, the right to take possession
of the Equipment or any part thereof, and to take such other measures as the
Mortgagee may deem necessary for the care, protection and preservation of the
Equipment.  Upon request or reasonable demand of the Mortgagee, the Mortgagor
shall at its expense assemble the Equipment and make it available to the
Mortgagee at the Premises or at such other mutually convenient place acceptable
to the Mortgagee.  The Mortgagor shall pay to the Mortgagee promptly following
written demand any and all expenses, including legal expenses and attorneys'
fees, incurred or paid by the Mortgagee in protecting its interest in the
Equipment and in enforcing its rights hereunder with respect to the Equipment.
Any notice of sale, disposition or other intended action by the Mortgagee with
respect to the Equipment sent to the Mortgagor in accordance with the provisions
of this Mortgage at least seven (7) days prior to the date of any such sale,
disposition or other action, shall constitute reasonable notice to the
Mortgagor, and the method of sale or disposition or other intended action set
forth or specified in such notice shall conclusively be deemed to be
commercially reasonable within the meaning of the Uniform Commercial Code unless
objected to in writing by the Mortgagor within five (5) days after receipt by
the Mortgagor of such notice.  The proceeds of any sale or disposition of the
Equipment, or any part thereof, may be applied by the Mortgagee to the payment
of the Debt in such order, priority and proportions as the Mortgagee in its
reasonable discretion shall deem proper.

          5.   Recovery of Sums Required To Be Paid.  The Mortgagee shall have
               ------------------------------------                           
the right from time to time to take action to recover any sum or sums which
constitute a part of the Debt as the same become due, without regard to whether
or not the balance of the Debt shall be due, and without prejudice to the right
of the Mortgagee thereafter to bring an action of foreclosure, or any other
action, for a default or defaults by the Mortgagor existing at the time such
earlier action was commenced.

          6.   Actions and Proceedings.  The Mortgagee shall have the right to
               -----------------------                                        
appear in and defend any action or proceeding brought with respect to the
Mortgaged Property and to bring any action or proceeding, in the name and on
behalf of the Mortgagor,

                                       17
<PAGE>
 
which the Mortgagee, in its discretion, feels should be brought to protect the
Mortgagee's interest in the Mortgaged Property.

          7.   Right to Cure Defaults.  Upon the occurrence or any default
               ----------------------                                     
hereunder, the Mortgagee may, at its discretion, remedy the same and for such
purpose shall have the right to enter upon the Mortgaged Property or any portion
thereof without thereby becoming liable to the Mortgagor or any person in
possession thereof holding under or claiming under or through the Mortgagor, it
being understood and agreed that nothing contained in this Mortgage shall in any
manner obligate the Mortgagee to remedy any default or appear in, defend, or
bring any action or proceeding to protect the Mortgagee's interest in the
Mortgaged Property or to foreclose this Mortgage or collect the Debt, the costs
and expenses thereof (including attorney's fees to the extent permitted by law),
with interest as provided in this paragraph, shall be paid by the Mortgagor to
the Mortgagee upon demand.  All such costs and expenses incurred by the
Mortgagee in remedying such default or in appearing in, defending, or bringing
any such action or proceeding shall be paid by the Mortgagor to the Mortgagee
promptly following written demand, with interest at a rate per annum (calculated
for the actual number of days elapsed on the basis of a 360-day year) equal to
the default rate of interest set forth in Section 3.2 of the Credit Agreement
(the "Default Rate"), provided, however, that the Default Rate shall in no event
exceed the maximum interest rate which the Mortgagor may by law pay, for the
period from the date of notice from the Mortgagee that such costs or expenses
were incurred to the date of payment thereof to the Mortgagee.  The term "Prime
Rate" shall mean such rate of interest as is publicly announced by the Mortgagee
at its principal office from time to time as its prime rate.  To the extent any
of the aforementioned costs or expenses paid by the Mortgagee after default by
the Mortgagor shall constitute payment of (i) taxes, charges or assessments
which may be imposed by law upon the Mortgaged Property, (ii) Premiums, (iii)
expenses incurred in upholding the lien of this Mortgage, including, but not
limited to, the costs and expenses of any litigation to collect the indebtedness
secured by this Mortgage or to prosecute, defend, protect or preserve the rights
and the lien created by this Mortgage, or (iv) any amount, cost or charge to
which the Mortgagee becomes subrogated, upon payment, whether under recognized
principles of law or equity, or under express statutory authority; then, and in
each such event, such costs, expenses and amounts, together with interest
thereon at the Default Rate, shall be added to the indebtedness secured by this
Mortgage and shall be secured by this Mortgage.

          8.   Late Payment Charge.  If any payment under the Notes or this
               -------------------                                         
Mortgage is not paid within ten (10) days after the date on which it is due, the
Mortgagor shall pay to the Mortgagee upon demand, in addition to any interest,
if any, payable pursuant to Paragraph 7 above, an amount equal to 5% of such
unpaid installment as a late payment charge.

                                       18
<PAGE>
 
          9.   Sole Discretion of Mortgagee.  Except as may otherwise be
               ----------------------------                             
expressly provided to the contrary, wherever pursuant to the Notes, this
Mortgage or any other document or instrument now or hereafter executed and
delivered in connection therewith or otherwise with respect to the loans secured
hereby, the Mortgagee exercises any right given to it to consent or not consent,
or to approve or disapprove, or any arrangement or term is to be satisfactory to
the Mortgagee, the decision of the Mortgagee to consent or not consent, or to
approve or disapprove, or to decide that arrangements or terms are satisfactory
or not satisfactory, shall be in the sole and absolute discretion of the
Mortgagee and shall be final and conclusive.

          10.  Non-Waiver.  The failure of the Mortgagee to insist upon strict
               ----------                                                     
performance of any term of this Mortgage shall not be deemed to be a waiver of
any term of this Mortgage.  No delay or omission by the Mortgagee to exercise
any right, power or remedy accruing under this Mortgage shall be construed to be
a waiver of any default or acquiescence therein.  A waiver in one or more
instances, and at the particular time or times only, and no such waiver shall be
deemed a continuing waiver, but every term, covenant, provision or condition
establishing such right, power or remedy shall survive and continue to remain in
full force and effect.  The Mortgagor shall not be relieved of the Mortgagor's
obligation to pay the Debt at the time and in the manner provided for its
payment in the Notes and this Mortgage by reason of: (i) failure of the
Mortgagee to comply with any request of the Mortgagor to take any action to
foreclose this Mortgage or otherwise enforce any of the provisions hereof or of
the Notes or any other mortgage, instrument or document evidencing, securing or
guaranteeing payment of the Debt or any portion thereof, (ii) the release,
regardless of consideration, of the whole or any part of the Mortgaged Property
or any other security for the Debt, or (iii) any agreement or stipulation
between the Mortgagee and any subsequent owner or owners of the Mortgaged
Property or other person extending the time of payment or otherwise modifying or
supplementing the terms of the Notes, this Mortgage or any other mortgage,
instrument or document evidencing, securing or guaranteeing payment of the Debt
or any portion thereof, without first having obtained the consent of the
Mortgagor, and in the latter event, the Mortgagor shall continue to be obligated
to pay the Debt at the time and in the manner provided in the Notes and this
Mortgage, as so extended, modified and supplemented, unless expressly released
and discharged from such obligation by the Mortgagee in writing.  Regardless of
consideration, and without the necessity for any notice to or consent by the
holder of any subordinate lien, encumbrance, right, title or interest in the
Mortgaged Property, the Mortgagee may release any person at any time liable for
the payment of the Debt or any portion thereof or any part of the security held
for the Debt and may extend the time of payment or otherwise modify the terms of
the Notes or this Mortgage, including, without limitation, a modification of the
interest rate payable on the

                                       19
<PAGE>
 
principal balance of the Notes, without in any manner impairing or affecting
this Mortgage or the lien hereof or the priority of this Mortgage, as so
extended and modified, as security for the Debt over any such subordinate lien,
encumbrance, right, title or interest.  The Mortgagee may resort for the payment
of the Debt to any other security held by the Mortgagee in such order and manner
as the Mortgagee, in its discretion, may elect.  The Mortgagee may take action
to recover the Debt, or any portion thereof, or to enforce any covenant hereof
without prejudice to the right of the Mortgagee thereafter to foreclose this
Mortgage.  The Mortgagee shall not be limited exclusively to the rights and
remedies herein stated but shall be entitled to every additional right and
remedy now or hereafter afforded by law or equity.  The rights of the Mortgagee
under this Mortgage shall be separate, distinct and cumulative and none shall be
given effect to the exclusion of the others.  No act of the Mortgagee shall be
construed as an election to proceed under any one provision herein to the
exclusion of any other provision.

          11.  Absolute and Unconditional Obligation.  The Mortgagor
               -------------------------------------                
acknowledges that the Mortgagor's obligation to pay the Debt in accordance with
the provisions of the Notes and this Mortgage is and shall at all times continue
to be absolute and unconditional in all respects, and shall at all times be
valid and enforceable irrespective of any other agreements or circumstances of
any nature whatsoever which might otherwise constitute a defense to the Notes or
this Mortgage or the obligation of the Mortgagor thereunder to pay the Debt or
the obligations of any other person relating to the Notes or this Mortgage or
the obligations of the Mortgagor under the Notes or this Mortgage or otherwise
with respect to the loans secured hereby, and the Mortgagor absolutely,
unconditionally and irrevocably waives any and all right to assert any setoff,
counterclaim or crossclaim of any nature whatsoever with respect to the
obligation of the Mortgagor to pay the Debt in accordance with the provisions of
the Notes and this Mortgage or the obligations of any other person relating to
the Notes or this Mortgage or obligations of the Mortgagor under the Notes or
this Mortgage or otherwise with respect to the loans secured hereby in any
action or proceeding brought by the Mortgagee to collect the Debt, or any
portion thereof, or to enforce, foreclose and realize upon the lien and security
interest created by this Mortgage or any other document or instrument securing
repayment of the Debt, in whole or in part (provided, however, that the
foregoing shall not be deemed a waiver of the Mortgagor's right to assert any
compulsory counterclaim maintained in a court of the United States, or of the
State of New York if such counterclaim is compelled under local law or rule of
procedure, nor shall the foregoing be deemed a waiver of the Mortgagor's right
to assert any claim which would constitute a defense, setoff, counterclaim or
crossclaim of any nature whatsoever against the Mortgagee in any separate action
or proceeding).

                                       20

          12.  Offsets, Counterclaims and Defenses.  Any assignee of this
               -----------------------------------                       
Mortgage and the Notes shall take the same free and clear of all offsets,
counterclaims or defenses of any nature whatsoever which the Mortgagor may have
against any assignor of this Mortgage and the Notes, and no such offset,
counterclaim or defense shall be interposed or asserted by the Mortgagor in any
action or proceeding brought by any such assignee upon this Mortgage or the
Notes and any such right to interpose or assert any such offset, counterclaim or
defense in any such action or proceeding is hereby expressly waived by the
Mortgagor.

          13./1/ Waiver of Statutory Rights.  The Mortgagor shall not and
                 --------------------------                              
will not apply for or avail itself of any appraisement, valuation, stay,
extension or exemption laws, or any so-called "Moratorium Laws," now existing or
hereafter enacted, in order to prevent or hinder the enforcement or foreclosure
of this Mortgage, but hereby waives the benefit of such laws to the full extent
that the Mortgagor may do so under applicable law.  The Mortgagor for itself and
all who may claim through or under it waives any and all right to have the
property and estates comprising the Mortgaged Property marshalled upon any
foreclosure of the lien of this Mortgage and agrees that any court having
jurisdiction to foreclose such lien may order the Mortgaged Property sold as an
entirety.  The Mortgagor hereby waives for itself and all who may claim through
or under it, and to the full extent Mortgagor may do so under applicable law,
any and all rights of redemption from sale under any order or decree of
foreclosure of this Mortgage or granted under any statute now existing or
hereafter enacted.

          14./1/ Waiver of Trial by Jury.  The Mortgagor hereby irrevocably
                 -----------------------                                   
and unconditionally waives, and the Mortgagee by its acceptance of the Notes and
this Mortgage irrevocably and unconditionally waives, any and all rights to
trial by jury in at any action, suit or counterclaim arising in connection with,
out of or otherwise relating to the Notes, this Mortgage or any other document
or instrument heretofore, now or hereafter executed and/or delivered in
connection therewith, the loans secured by this Mortgage or in any way related
to this transaction or otherwise with respect to the Mortgaged Property.

          2.   Waiver of Notice.  The Mortgagor shall not be entitled to any

after the date of this Mortgage of any law of the State of New York deducting
from the value of real property for the purpose of taxation any lien or
encumbrance thereon or changing in any way the laws for the taxation of
mortgages or debts secured by mortgages for state or local purposes or the
manner of the collection of any such taxes, and imposing a tax, either directly
or indirectly, on this Mortgage, the Notes or the Debt, the Mortgagor shall, if
permitted by law, pay any tax imposed as a result of any such law within the
statutory period or within fifteen (15) days after demand by the Mortgagee,
whichever is less, provided, however, that if, in the opinion of the attorneys
for the Mortgagee, the Mortgagor is not permitted by law to pay such taxes, the
Mortgagee shall have the right, at its option, to declare the Debt due and
payable on a date specified in a prior notice to the Mortgagor of not less than
thirty (30) days.

          5.   No Credits on Account of the Debt.  The Mortgagor will not claim

<PAGE>
 
will, upon demand, pay for the same, with interest and penalties thereon, if

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

Mortgage and any extension, modification, renewal or replacement hereof, and any
security instrument creating a lien or evidencing the lien hereof upon the
Mortgaged Property and each instrument of further assurance to be filed,
registered or recorded in such manner and in such places as may be required by
any present of future law in order to publish notice of and fully to protect,
preserve and perfect the lien hereof upon, and the interest of the Mortgagee in,
the Mortgaged Property.  The Mortgagor will pay all title insurance fees and
charges, all filing, registration and recording fees, and all expenses incident
to the preparation, execution and acknowledgment of this Mortgage, any mortgage
supplemental hereto, any security instrument with respect to the Mortgaged
Property, and any instrument of further assurance, and all Federal, State,
county and municipal taxes, duties, imposts, assessments and charges arising out
of or in connection with the execution and delivery of this Mortgage, any

Mortgaged Property or any instrument of further assurance.  The Mortgagor shall
hold harmless and indemnify the Mortgagee, its successors and assigns, against
any liability incurred by reason of the imposition of any tax on the making and
recording of this Mortgage.

          8.   Further Acts, etc.  The Mortgagor will, at the cost of the
               ------------------                                        
Mortgagor, and without expense to the Mortgagee, do, execute, acknowledge and
deliver all and every such further acts, deeds, conveyances, mortgages,
assignments, notices of assignments, transfers and assurances as the Mortgagee
shall, from time to time, require for the better assuring, conveying, assigning,
transferring and confirming unto the Mortgagee the property and rights hereby
mortgaged or intended now or hereafter so to be, or which the Mortgagor may be
or may hereafter become bound to convey or assign to the Mortgagee, or for
carrying out the intention or facilitating the performance of the terms of this
Mortgage or for filing, registering or recording this Mortgage and, on demand,
will execute and deliver and hereby authorizes the Mortgagee to execute in the
name of the Mortgagor to the extent the Mortgagee may lawfully do so, one or
more financing statements, chattel mortgages or comparable security instruments,
to evidence more effectively the lien hereof upon the Mortgaged Property.

          9.   Usury Laws.  This Mortgage and the Notes are subject to the
               ----------                                                 
express condition that at no time shall the Mortgagor be obligated or required
to pay interest on the principal balance due under the Notes at a rate which
could subject the holder of the Notes to either civil or criminal

                                       24
<PAGE>
 
liability as a result of being in excess of the maximum interest rate which the
Mortgagor is permitted by law to contract or agree to pay.  If, by the terms of
this Mortgage or the Notes, the Mortgagor is at any time required or obligated
to pay interest on the principal balance due under the Notes at a rate in excess
of such maximum rate, the rate of interest under the Notes shall be deemed to be
immediately reduced to such maximum rate and the interest payable shall be
computed at such maximum rate and all prior interest payments in excess of such
maximum rate shall be applied and shall be deemed to have been payments in
reduction of the principal balance of the Notes.

          10.  Brokerage.  The Mortgagor covenants and agrees that no brokerage
               ---------                                                       
commission or other fee, commission or compensation is to be paid by the
Mortgagee and the Mortgagor agrees to indemnify the Mortgagee against any claims
for any of the same.

          11.  Indemnity.  Anything in this Mortgage or the other Loan Documents
               ---------                                                        
to the contrary notwithstanding, the Mortgagor shall indemnify and hold the
Mortgagee harmless and defend the Mortgagee at the Mortgagor's sole cost and
expense against any loss or liability, cost or expense (including, without
limitation, reasonable attorneys' fees and disbursements of the Mortgagee's
counsel, whether in-house staff, retained firms or otherwise), and all claims,
actions, procedures and suits arising out of or in connection with (i) any
ongoing matters arising out of the transaction contemplated hereby, the Debt,
this Mortgage, the Notes or any other document or instrument now or hereafter
executed and/or delivered in connection with the Debt (the "Loan Documents")
including, but not limited to, all costs of reappraisal of the Mortgaged
Property or any part thereof, whether required by law, regulation, the Mortgagee
or any governmental or quasi-governmental authority, (ii) any amendment to, or
restructuring of, the Debt and this Mortgage, the Notes or any of the other Loan
Documents, and (iii) any and all lawful action that may be taken by the
Mortgagee in connection with the enforcement of the provisions of this Mortgage
or the Notes or any of the other Loan Documents, whether or not suit is filed in
connection with the same, or in connection with the Mortgagor, any Guarantor
and/or any partner, joint venturer or shareholder thereof becoming a party to a
voluntary or involuntary Federal or state bankruptcy, insolvency, or similar
proceeding.  All sums expended by the Mortgagee shall be deemed additional
principal of the Debt and secured hereby and shall bear interest at the Default
Rate.  The obligations of the Mortgagor under this paragraph shall,
notwithstanding any exculpatory or other provisions of any nature whatsoever set
forth in the Loan Documents, constitute the personal recourse undertakings,
obligations and liabilities of the Mortgagor.

          12.  No Oral Change.  This Mortgage may only be modified, amended or
               --------------                                                 
changed by an agreement in writing signed by

                                       25
<PAGE>
 
the Mortgagor and the Mortgagee, and may only be released, discharged or
satisfied of record by an agreement in writing signed by the Mortgagee.  No
waiver of any term, covenant or provision of this Mortgage shall be effective
unless given in writing by the Mortgagee and if so given by the Mortgagee shall
only be effective in the specific instance in which given.  The Mortgagor
acknowledges that the Notes, this Mortgage and the other documents and
instruments executed and delivered in connection therewith or otherwise in
connection with the loans secured hereby set forth the entire agreement and
understanding of the Mortgagor and the Mortgagee with respect to the loans
secured hereby and that no oral or other agreement, understanding,
representation or warranty exists with respect to the loans secured hereby other
than those set forth in the Notes, this Mortgage and such other executed and
delivered documents and instruments.

          13.  Enforceability.  This Mortgage was negotiated in the State of New
               --------------

laws of the State of New York applicable to contracts made and performed in such
State and any applicable laws of the United States of America, it being
understood that, to the fullest extent permitted by the law of such State, the
law of the State of New York shall govern the validity and enforceability of
this Mortgage, and the obligations arising hereunder, the parties hereto
recognizing that the Credit Agreement and the Notes are governed by, and
construed in accordance with, the laws of the State of California.  Whenever
possible, each provision of this Mortgage shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision of this
Mortgage shall be unenforceable or prohibited by or invalid under applicable
law, such provision shall be ineffective to the extent of such unenforceability,
prohibition or invalidity, without invalidating the remaining provisions of this
Mortgage.

          14.  Relationship.  The relationship of the Mortgagee to the Mortgagor
               ------------

mortgagee and nothing contained in the Notes, this Mortgage or any other
document or instrument now or hereafter executed and delivered in connection
therewith or otherwise in connection with the loans secured hereby is intended

creating, a partnership, joint venture, tenancy-in-common, joint tenancy or
other relationship of any nature whatsoever between the Mortgagee and the
Mortgagor other than as lender and borrower and mortgagor and mortgagee.

          20.  Reasonableness.  If at any time the Mortgagor believes that the
               --------------                                                 
Mortgagee has not acted reasonably in granting or withholding any approval or
consent under the Notes, this Mortgage or any other document or instrument now
or hereafter executed and delivered in connection therewith or otherwise with
respect to the loans secured hereby, as to which approval or consent either the
Mortgagee has expressly agreed to act reasonably, or absent such agreement, a
court of law having jurisdiction over the subject matter would require the
Mortgagee to act reasonably, then the Mortgagor's sole remedy shall be to seek
injunctive relief or specific performance and no action for monetary damages or

                       ARTICLE III.  ASSIGNMENT OF RENTS
                                     -------------------

     3.01  Assignment.  For the purposes and upon the terms and conditions set
           ----------                                                         
forth herein, Trustor irrevocably assigns to Beneficiary all of Trustor's right,
title and interest in, to and under all leases, licenses, rental agreements and
other agreements of any kind relating to the use or occupancy of any of the
Subject Property, whether existing as of the date hereof or at any time
hereafter entered into, together with all guarantees of and security for any
tenant's or lessee's performance thereunder, and all amendments, extensions,
renewals and modifications thereto (each, a "Lease" and collectively, the
"Leases"), together with any and all other rents, issues and profits of the
Subject Property (collectively, "Rents").  This Assignment shall not impose upon
Beneficiary any duty to produce Rents from the Subject Property, nor cause
Beneficiary to be (a) a "mortgagee in possession" for any purpose so long as
Beneficiary has not itself entered into actual possession of the Subject
Property, (b) responsible for performing any of the obligations of the lessor or
landlord under any Lease, or (c) responsible for any waste committed by any
person or entity at any time in possession of the Subject Property or any part
thereof, or for any dangerous or defective condition of the Subject Property, or
for any negligence in the management, upkeep, repair or control of the Subject
Property, but the foregoing shall not relieve Beneficiary of responsibility for
damages arising from its gross negligence or willful misconduct. This is an
absolute assignment, not an assignment for security only, and Beneficiary's
right to Rents is not contingent upon and may be exercised without possession of
the Subject Property. Trustor agrees to execute and deliver to Beneficiary,
within five (5) days of Beneficiary's written request, such additional documents
as Beneficiary or Trustee may reasonably request to further evidence the
assignment to Beneficiary of any and all Leases and Rents.

     3.02  Protection of Security.  To protect the security of this Assignment,
           ----------------------                                              
Trustor agrees:

     (a) At Trustor's sole cost and expense:  (i) to perform each obligation to
be performed by the lessor or landlord under each Lease and to enforce or secure
the performance of each obligation to be performed by the lessee or tenant under
each Lease; (ii) not to modify any Lease in any material respect, nor accept
surrender under or terminate the term of any Lease except in accordance with the
terms thereof; (iii) not to anticipate the Rents under any Lease; and (iv) not
to waive or release any lessee or tenant of or from any Lease 
obligations. Trustor assigns to Beneficiary all of Trustor's right and power to
modify the terms of any Lease, to accept a surrender under or terminate the term
of or anticipate the Rents under any Lease, and to waive or release any lessee
or tenant of or from any Lease 

                                      -3-
<PAGE>
 
obligations, and any attempt on the part of Trustor to exercise any such rights
or powers without Beneficiary's prior written consent shall be a breach of the
terms hereof.

     (b) At Trustor's sole cost and expense, to defend any action in any manner
connected with any Lease or the obligations thereunder, and to pay all costs of
Beneficiary or Trustee, including reasonable attorneys' fees, in any such action
relating to a Lease in which Beneficiary or Trustee may appear.

     (c) That, should Trustor fail to do any act required to be done by Trustor
under a Lease within the applicable time period (including any grace period) set
forth therein, then Beneficiary or Trustee, but without obligation to do so and
without notice to Trustor and without releasing Trustor from any obligation
hereunder, may make or do the same in such manner and to such extent as
Beneficiary or Trustee deems necessary to protect the security hereof, and, in
exercising such powers, Beneficiary or Trustee may employ attorneys and other
agents, and Trustor shall pay necessary costs and reasonable attorneys' fees
incurred by Beneficiary or Trustee, or their agents, in the exercise of the
powers granted herein.  Trustor shall give prompt notice to Beneficiary of any
default by any lessee or tenant under any Lease, and of any notice of default on
the part of Trustor under any Lease received from a lessee or tenant thereunder,
together with an accurate and complete copy thereof.

     (d) To pay to Beneficiary immediately upon demand all sums expended under
the authority hereof, including reasonable attorneys' fees, together with
interest thereon at the then-current rate per annum payable under any Secured
Obligation, and the same may, at Beneficiary's option, be added to any Secured
Obligation and shall be secured hereby.

     3.03  License.  Beneficiary confers upon Trustor a license ("License") to
           -------                                                            
collect and retain the Rents as, but not more than 30 days before, they come due
and payable, until the occurrence of any Default.  Upon the occurrence of any
Default, the License shall be automatically revoked, and Beneficiary or Trustee
may, at Beneficiary's option and without notice, either in person or by agent,
with or without bringing any action, or by a receiver to be appointed by a
court:  (a) enter, take possession of, manage and operate the Subject Property
or any part thereof; (b) make, cancel, enforce or modify any Lease; (c) obtain
and evict tenants, fix or modify Rents, and do any acts which Beneficiary or
Trustee deems proper to protect the security hereof; and (d) either with or
without taking possession of the Subject Property, in its own name, sue for or
otherwise collect and receive all Rents, including those past due and unpaid,
and apply the same in accordance with the provisions of Section 5.04 hereof.
The entering and taking possession of the Subject Property, the collection of
Rents and the application thereof as aforesaid, shall not cure or waive any
Default, nor waive, modify or affect any notice of default hereunder, nor
invalidate any act done pursuant to such notice.  The License shall not grant to
Beneficiary or Trustee the right to possession, except as provided in this Deed
of Trust.  Upon Trustor's complete cure of such Default, the License shall be
reinstated by Beneficiary and thereafter continue in accordance with (and
subject to the conditions of) this Section 3.03.


                 ARTICLE IV.  RIGHTS AND DUTIES OF THE PARTIES
                              --------------------------------

     4.01  Title.  Trustor warrants that, except as otherwise disclosed to
           -----                                                          
Beneficiary prior to the date hereof in a writing which refers to this warranty,
Trustor lawfully possesses and holds fee simple title to the Subject Property
without limitation on the right to encumber and assign its interest therein, as
herein provided, and that this Deed of Trust is a valid lien on the Subject
Property and all of Trustor's interest therein.

                                      -4-
<PAGE>
 
     4.02  Taxes and Assessments.  Trustor shall pay prior to delinquency all
           ---------------------                                             
taxes, assessments, levies and charges imposed (a) by any public or quasi-public
authority or utility company which are or which may become a lien upon or cause
a loss in value of the Subject Property or any interest therein, or (b) by any
public authority upon Beneficiary by reason of its interest in any Secured
Obligation or in the Subject Property, or by reason of any payment made to
Beneficiary pursuant to any Secured Obligation; but Trustor shall have no
obligation to pay any income taxes of Beneficiary.  Trustor shall have the right
to contest in good faith the amount or validity of any such taxes, assessments,
levies and charges by appropriate legal or administrative proceedings diligently
pursued, so long as the lien of this Deed of Trust shall not be adversely
affected by such contest.

     4.03  Performance of Secured Obligations.  Trustor shall promptly pay and
           ----------------------------------                                 
perform each Secured Obligation when due.

     4.04  Liens, Encumbrances and Charges.  Trustor shall immediately discharge
           -------------------------------                                      
any lien not approved by Beneficiary in writing that has or may attain priority
over this Deed of Trust. Except as otherwise provided in any Secured Obligation
or other agreement with Beneficiary, Trustor shall pay when due all obligations
secured by or reducible to liens and encumbrances which shall now or hereafter
encumber the Subject Property, whether senior or subordinate hereto, including
without limitation, any mechanics' liens.  Trustor shall have the right to
contest in good faith the amount or validity of any such lien or encumbrance by
appropriate legal or administrative proceedings diligently pursued, so long as
the lien of this Deed of Trust shall not be adversely affected by such contest.

     4.05  Insurance.  Trustor shall insure the Subject Property against loss or
           ---------                                                            
damage by fire and such other risks as Beneficiary shall from time to time
require.  Trustor shall carry public liability insurance, flood insurance as
required by applicable law and such other insurance as Beneficiary may
reasonably require, including without limitation, business interruption
insurance or loss of rental value insurance.  Trustor shall maintain all
required insurance at Trustor's expense, under policies issued by companies and
in form and substance satisfactory to Beneficiary.  Neither Beneficiary nor
Trustee, by reason of accepting, rejecting, approving or obtaining insurance
shall incur any liability for: (a) the existence, nonexistence, form or legal
sufficiency thereof; (b) the solvency of any insurer; or (c) the payment of
losses.  All policies and certificates of insurance shall name Beneficiary as
loss payee, and shall provide that the insurance cannot be terminated as to
Beneficiary except upon a minimum of ten (10) days' prior written notice to
Beneficiary.  Immediately upon any request by Beneficiary, Trustor shall deliver
to Beneficiary the original of all such policies or certificates, with receipts
evidencing annual prepayment of the premiums.

     4.06  Security Account.  Upon the occurrence and during the continuation of
           ----------------                                                     
a Default under this Deed of Trust, Beneficiary may require, at its option, but
subject to applicable law and to any specific limits on exercise of that option
contained herein, that Trustor pay to Beneficiary each month an additional sum
estimated by Beneficiary to be equal to the annual amount of (a) taxes, bonds,
assessments, levies and charges described in Section 4.02 hereof, and (b)
premiums for fire and other hazard and mortgage insurance next due, divided by,
in each instance, the number of months to lapse before one month before said
annual amount will become due.  Such payments of additional sums by Trustor to
Beneficiary shall be held in a security account, and Trustor hereby grants and
transfers to Beneficiary a security interest in all sums so held in said
security account, and all proceeds thereof, to secure the payment and
performance of each Secured Obligation.  All sums so paid shall not bear
interest, except to the extent and in the amount required by law.  Beneficiary
shall apply said sums to the payment of, or at the sole option of Beneficiary,
release said sums to Trustor for application to and payment of, such taxes,
bonds, assessments, levies, charges and insurance premiums.  If the amount so
deposited by Trustor 

                                      -5-
<PAGE>
 
is insufficient to pay the installment of the taxes, bonds, assessments, levies,
charges or insurance premiums then due, and Trustor fails to deposit the amount
of such deficiency promptly upon Beneficiary's notice to Trustor of the amount
of such deficiency, then Beneficiary at its sole option may apply all or any
part of said sums to any Secured Obligation. The relationship between
Beneficiary and Trustor with respect to said security account shall be one of
debtor-creditor, and not one where Beneficiary shall be deemed a trustee,
special depository or other fiduciary acting for the benefit of Trustor. The
existence of said security account shall not limit Beneficiary's rights under
any other provision of this Deed of Trust or any other agreement or statute or
rule of law. Beneficiary may refund any sums in the Security Account which
exceed the total amount to be paid therefrom for any year, or may continue to
hold the excess and reduce proportionately the required monthly deposits for the
next year.

     4.07  Damages; Insurance and Condemnation Proceeds.
           -------------------------------------------- 

     (a)  (i) All awards of damages and all other compensation payable directly
or indirectly by reason of a condemnation or proposed condemnation for public or
private use affecting the Subject Property; (ii) all other claims and awards for
damages to or decrease in value of the Subject Property; (iii) all proceeds of
any insurance policies payable by reason of loss sustained to the Subject
Property; and (iv) all interest which may accrue on any of the foregoing, are
all absolutely and irrevocably assigned to and shall be paid to Beneficiary.  If
a Default then has occurred and is continuing, or if Beneficiary otherwise
reasonably determines that its security is or may be impaired, then, at the
absolute discretion of Beneficiary, but subject to applicable law, if any, and
without regard to any requirement contained in Section 4.08(c) hereof,
Beneficiary may apply all or any of the proceeds it receives to its expenses in
settling, prosecuting or defending any such claim and apply the balance to the
Secured Obligations in any order, and release all or any part of the proceeds to
Trustor upon any conditions Beneficiary reasonably may impose.  If a Default is
not then continuing, or if Beneficiary's security is not impaired, then such
proceeds shall be released to Trustor upon such conditions Beneficiary
reasonably may impose. Beneficiary may commence, appear in, defend or prosecute
any assigned claim or action, and may adjust, compromise, settle and collect all
claims and awards assigned to Beneficiary, but shall not be responsible for any
failure to collect any claim or award, regardless of the cause of the failure.
Nothing in this Section 4.07(a) shall prevent Trustor from commencing, appearing
in, defending or prosecuting any claim or action, or adjusting, compromising,
settling and collecting any claims and awards, if Beneficiary fails to do so in
a timely manner.

     (b) At its sole option, Beneficiary may permit insurance or condemnation
proceeds held by Beneficiary to be used for repair or restoration but may impose
any conditions on such use as Beneficiary reasonably deems necessary.

     4.08  Maintenance and Preservation of Subject Property.  Subject to the
           ------------------------------------------------                 
provisions of any Secured Obligation, Trustor covenants:

     (a) to keep the Subject Property in good condition and repair ordinary wear
and tear excepted;

     (b) except with Beneficiary's prior written consent (except as necessary to
comply with applicable laws), not to remove or demolish the Subject Property,
not to alter, restore or add to the Subject Property, and not to initiate or
join in the application for any change in any zoning or other land
classification which affects the Subject Property;

     (c) to restore promptly and in good workmanlike manner any portion of the
Subject Property which may be damaged or destroyed, unless Beneficiary requires
that all of 

                                      -6-
<PAGE>
 
the insurance proceeds be used to reduce the Secured Obligations as provided in
Section 4.07 hereof;

     (d)   to comply with and not to suffer violation of any or all of the
following which govern acts or conditions on, or otherwise affect the Subject
Property:  (i) laws, ordinances, regulations, standards and judicial and
administrative rules and orders; (ii) covenants, conditions, restrictions and
equitable servitudes, whether public or private; and (iii) requirements of
insurance companies and any bureau or agency which establishes standards of
insurability;

     (e)   not to commit or permit waste of the Subject Property; and

     (f)   to do all other acts which from the character or use of the Subject
Property may be reasonably necessary to maintain and preserve its value.

     4.09  Hazardous Substances; Environmental Provisions.  Trustor represents
           ----------------------------------------------                     
and warrants to Beneficiary that, except as disclosed to, and acknowledged by,
Beneficiary in writing prior to the date hereof:  (a) to the best of Trustor's
knowledge, during the period of Trustor's ownership or possession of the Subject
Property, there has been no use, generation, manufacture, storage, treatment,
disposal, release or threatened release of any hazardous waste or hazardous
substance (as said terms are defined in the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended, the Superfund
Amendments and Reauthorization Act of 1986, any other applicable state or
Federal environmental laws, and any rules or regulations adopted pursuant to any
of the foregoing) by any person from, on, under or about the Subject Property;
and (b) to the best of Trustor's knowledge, there has not been (i) any use,
generation, manufacture, storage, treatment, disposal, release or threatened
release of any hazardous waste or hazardous substance by any prior owners or
occupants of the Subject Property, or (ii) any actual or threatened litigation
or claims of any kind by any person relating to such matters.  Trustor agrees to
indemnify and hold Beneficiary harmless from and against any and all claims,
losses, liabilities, damages, penalties and expenses of any kind or character,
including reasonable attorneys' fees, which Beneficiary may directly or
indirectly sustain or suffer as a result of (x) any breach of this Section 4.09,
or (y) as a consequence of any use, generation, manufacture, storage, treatment,
disposal, release or threatened release occurring prior to Trustor's ownership
of any interest in the Subject Property, whether or not the same was or should
have been known to Trustor.  This obligation to indemnify shall survive the
payment of the Secured Obligations and the satisfaction of this Deed of Trust,
and shall not be affected by Beneficiary's acquisition of any interest in the
Subject Property, whether by foreclosure or otherwise.

     Trustor and Beneficiary agree that this Section 4.09 is intended as
Beneficiary's written request for information (and Trustor's response)
concerning the environmental condition of the Subject Property as required by
California Code of Civil Procedure (S)726.5, and that each representation and
warranty contained in this Section 4.09 (together with any indemnity applicable
to a breach of any such representation and warranty) with respect to the
environmental condition of the Subject Property is intended by Trustor and
Beneficiary to be an "environmental provision" for purposes of California Code
of Civil Procedure (S)736.

     4.10  Protection of Security.  Trustor shall, at Trustor's sole expense:
           ----------------------                                             
(a) protect, preserve and defend the Subject Property and Trustor's title and
right to possession of the Subject Property against all adverse claims; (b) if
Trustor's interest in the Subject Property is a leasehold interest or estate,
pay and perform in a timely manner all obligations to be paid and/or performed
by the lessee or tenant under the lease or other agreement creating such
leasehold interest or estate; and (c) protect, preserve and defend the security
of this Deed of 

                                      -7-
<PAGE>
 
Trust and the rights and powers of Beneficiary and Trustee under this Deed of
Trust against all adverse claims. Trustor shall give Beneficiary and Trustee
prompt notice in writing of the assertion of any claim, the filing of any action
or proceeding, or the occurrence of any damage, condemnation offer or other
action relating to or affecting the Subject Property and, if Trustor's interest
in the Subject Property is a leasehold interest or estate, of any notice of
default or demand for performance under the lease or other agreement pursuant to
which such leasehold interest or estate was created or exists.

     4.11  Acceptance of Trust; Powers and Duties of Trustee.  Trustee accepts
           -------------------------------------------------                  
this trust when this Deed of Trust is executed. From time to time, upon written
request of Beneficiary and presentation of this Deed of Trust for endorsement,
and without affecting the personal liability of any person for payment of any
indebtedness or performance of any of the Secured Obligations, Trustee may,
without obligation to do so and without liability therefor and without notice:
(a) reconvey all or any part of the Subject Property; (b) consent to the making
of any map or plat of the Subject Property; and (c) join in any grant of
easement thereon, any declaration of covenants and restrictions, any extension
agreement or any agreement subordinating the lien or charge of this Deed of
Trust. Trustee or Beneficiary may from time to time apply to any court of
competent jurisdiction for aid and direction in the execution of the trusts and
the enforcement of the rights and remedies available under this Deed of Trust,
and may obtain orders or decrees directing or confirming or approving acts in
the execution of said trusts and the enforcement of said rights and remedies.
Trustee has no obligation to notify any party of any pending sale or any action
or proceeding (including, but not limited to, actions in which Trustor,
Beneficiary or Trustee shall be a party) unless held or commenced and maintained
by Trustee under this Deed of Trust. Trustee shall not be obligated to perform
any act required of it under this Deed of Trust unless the performance of the
act is requested in writing and Trustee is reasonably indemnified against all
losses, costs, liabilities and expenses in connection therewith.

     4.12  Compensation; Exculpation; Indemnification.
           ------------------------------------------ 

     (a) Trustor shall pay all Trustee's fees and reimburse Trustee for all
expenses in the administration of this trust, including reasonable attorneys'
fees.  Trustor shall pay Beneficiary reasonable compensation for services
rendered concerning this Deed of Trust, including without limitation, the
providing of any statement of amounts owing under any Secured Obligation.
Beneficiary shall not directly or indirectly be liable to Trustor or any other
person as a consequence of:  (i) the exercise of any of the rights, remedies or
powers granted to Beneficiary in this Deed of Trust (other than with respect to
Beneficiary's gross negligence or willful misconduct in connection with such
exercise); (ii) the failure or refusal of Beneficiary to perform or discharge
any obligation or liability of Trustor under any Lease or other agreement
related to the Subject Property or under this Deed of Trust; or (iii) any loss
sustained by Trustor or any third party as a result of Beneficiary's failure to
lease the Subject Property after any Default or from any other act or omission
of Beneficiary in managing the Subject Property after any Default unless such
loss is caused by the willful misconduct or gross negligence of Beneficiary; and
no such liability shall be asserted or enforced against Beneficiary, and to the
extent permitted by law all such liability is hereby expressly waived and
released by Trustor.

     (b) Trustor shall indemnify Trustee and Beneficiary against, and hold them
harmless from, any and all losses, damages, liabilities, claims, causes of
action, judgments, court costs, attorneys' fees and other legal expenses, costs
of evidence of title, costs of evidence of value, and other expenses which
either may suffer or incur:  (i) by reason of this Deed of Trust; (ii) by reason
of the execution of this trust or the performance of any act required or
permitted hereunder or by law; (iii) as a result of any failure of Trustor to
perform Trustor's obligations; or (iv) by reason of any alleged obligation or
undertaking of 

                                      -8-
<PAGE>
 
Beneficiary to perform or discharge any of the representations, warranties,
conditions, covenants or other obligations contained in any other document
related to the Subject Property, including without limitation, the payment of
any taxes, assessments, rents or other lease obligations, liens, encumbrances or
other obligations of Trustor under this Deed of Trust (other than with respect
to Beneficiary's or Trustee's gross negligence or willful misconduct). Trustor's
duty to indemnify Trustee and Beneficiary shall survive the payment, discharge
or cancellation of the Secured Obligations and the release or reconveyance, in
whole or in part, of this Deed of Trust.

     (c) Trustor shall pay all indebtedness arising under this Section 4.12
immediately upon demand by Trustee or Beneficiary, together with interest
thereon from the date such indebtedness arises at the then-current rate per
annum payable under any Secured Obligation. Beneficiary may, at its option, add
any such indebtedness to any Secured Obligation.

     4.13  Substitution of Trustees.  From time to time, by a writing signed and
           ------------------------                                             
acknowledged by Beneficiary and recorded in the Office of the Recorder of the
County in which the Subject Property is situated, Beneficiary may appoint
another trustee to act in the place and stead of Trustee or any successor. Such
writing shall set forth the date, book and page of its recordation and any other
information required by law. The recordation of such instrument of substitution
shall discharge Trustee herein named and shall appoint the new trustee as the
trustee hereunder with the same effect as if originally named Trustee herein. A
writing recorded pursuant to the provisions of this Section 4.13 shall be
conclusive proof of the proper substitution of such new Trustee.

     4.14  Due on Sale or Encumbrance.  Except as permitted by the provisions of
           --------------------------                                           
any Secured Obligation or applicable law, if the Subject Property or any
interest therein shall be sold, transferred, mortgaged, assigned, encumbered or
leased, whether voluntarily, involuntarily or by operation of law (each of which
actions and events is called a "Transfer"), without Beneficiary's prior written
consent (which, in the case of leases, will not be unreasonably withheld), then
Beneficiary may, at its sole option, declare all Secured Obligations immediately
due and payable in full.  Trustor shall notify Beneficiary in writing of each
Transfer within ten (10) business days of the date thereof.

     4.15  Releases, Extensions, Modifications and Additional Security.  Without
           -----------------------------------------------------------          
notice to or the consent, approval or agreement of any persons or entities
having any interest at any time in the Subject Property or in any manner
obligated under any Secured Obligation ("Interested Parties"), Beneficiary may,
from time to time, release any of the Interested Parties from liability for the
payment of any Secured Obligation, take any action or make any agreement
extending the maturity or otherwise altering the terms or increasing the amount
of any Secured Obligation, accept additional security, and enforce, waive,
subordinate or release all or a portion of the Subject Property or any other
security for any Secured Obligation.  None of the foregoing actions shall
release or reduce the personal liability of any of the Interested Parties, nor
release or impair the priority of the lien of this Deed of Trust upon the
Subject Property.

     4.16  Reconveyance.  Upon Beneficiary's written request, and upon surrender
           ------------                                                         
of this Deed of Trust and every note or other instrument setting forth any
Secured Obligations to Trustee for cancellation, Trustee shall reconvey, without
warranty, the Subject Property or that portion thereof then covered hereby.  The
recitals of any matters or facts in any reconveyance executed hereunder shall be
conclusive proof of the truthfulness thereof.  To the extent permitted by law,
the reconveyance may describe the grantee as "the person or persons legally
entitled thereto." Neither Beneficiary nor Trustee shall have any duty to
determine the rights of persons claiming to be rightful grantees of any
reconveyance.  When the Subject Property has been fully reconveyed, the last
such reconveyance shall operate as a 

                                      -9-
<PAGE>
 
reassignment of all future Rents to the person or persons legally entitled
thereto. Upon Beneficiary's demand, Trustor shall pay all reasonable costs and
expenses incurred by Beneficiary in connection with any reconveyance.

     4.17  Subrogation.  Beneficiary shall be subrogated to the lien of all
           -----------                                                     
encumbrances, whether released of record or not, paid in whole or in part by
Beneficiary pursuant to this Deed of Trust or by the proceeds of any Secured
Obligation.

     4.18  Trustor Different From Obligor ("Third Party Trustor").  As used in
           ------------------------------------------------------             
this Section 4.18, the term "Obligor" shall mean each person or entity which is
obligated in any manner under any of the Secured Obligations; and the term
"Third Party Trustor" shall mean (1) each person or entity which is included in
the definition of Trustor herein and which is not an Obligor under all of the
Secured Obligations, and (2) each person or entity which is included in the
definition of Trustor herein if there is any Obligor which is not included in
said definition of Trustor.

     (a) Representations and Warranties.  Each Third Party Trustor represents
         ------------------------------                                      
and warrants to Beneficiary that: (i) this Deed of Trust is executed at an
Obligor's request; (ii) this Deed of Trust complies with all agreements between
each Third Party Trustor and any Obligor regarding such Third Party Trustor's
execution hereof; (iii) Beneficiary has made no representation to any Third
Party Trustor as to the creditworthiness of any Obligor; and (iv) each Third
Party Trustor has established adequate means of obtaining from each Obligor on a
continuing basis financial and other information pertaining to such Obligor's
financial condition. Each Third Party Trustor agrees to keep adequately informed
from such means of any facts, events or circumstances which might in any way
affect such Third Party Trustor's risks hereunder. Each Third Party Trustor
further agrees that Beneficiary shall have no obligation to disclose to any
Third Party Trustor any information or material about any Obligor which is
acquired by Beneficiary in any manner. The liability of each Third Party Trustor
hereunder shall be reinstated and revived, and the rights of Beneficiary shall
continue if and to the extent that for any reason any amount at any time paid on
account of any Secured Obligation is rescinded or must otherwise be restored by
Beneficiary, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, all as though such amount had not been paid. The
determination as to whether any amount so paid must be rescinded or restored
shall be made by Beneficiary in its sole discretion; provided however, that if
Beneficiary chooses to contest any such matter at the request of any Third Party
Trustor, each Third Party Trustor agrees to indemnify and hold Beneficiary
harmless from and against all costs and expenses, including reasonable
attorneys' fees, expended or incurred by Beneficiary in connection therewith,
including without limitation, in any litigation with respect thereto.

     (b)  Waivers.
          ------- 

          (i) Each Third Party Trustor waives any right to require Beneficiary
to:  (A) proceed against any Obligor or any other person; (B) proceed against or
exhaust any security held from any Obligor or any other person; (C) give notice
of the terms, time and place of any public or private sale of personal property
security held from any Obligor or any other person, or otherwise comply with any
other provisions of Section 9504 of the California Uniform Commercial Code; (D)
pursue any other remedy in Beneficiary's power; or (E) make any presentments or
demands for performance, or give any notices of nonperformance, protests,
notices of protest or notices of dishonor in connection with any obligations or
evidences of indebtedness held by Beneficiary as security for or which
constitute in whole or in part the Secured Obligations, or in connection with
the creation of new or additional obligations.

                                      -10-
<PAGE>
 
         (ii) Each Third Party Trustor waives any defense to its obligations
hereunder based upon or arising by reason of: (A) any disability or other
defense of any Obligor or any other person; (B) the cessation or limitation from
any cause whatsoever, other than payment in full, of any Secured Obligation; (C)
any lack of authority of any officer, director, partner, agent or any other
person acting or purporting to act on behalf of any Obligor which is a
corporation, partnership or other type of entity, or any defect in the formation
of any such Obligor; (D) the application by any Obligor of the proceeds of any
Secured Obligation for purposes other than the purposes represented by any
Obligor to, or intended or understood by, Beneficiary or any Third Party
Trustor; (E) any act or omission by Beneficiary which directly or indirectly
results in or aids the discharge of any Obligor or any portion of any Secured
Obligation by operation of law or otherwise, or which in any way impairs or
suspends any rights or remedies of Beneficiary against any Obligor; (F) any
impairment of the value of any interest in any security for the Secured
Obligations or any portion thereof, including without limitation, the failure to
obtain or maintain perfection or recordation of any interest in any such
security, the release of any such security without substitution, and/or the
failure to preserve the value of, or to comply with applicable law in disposing
of, any such security; or (G) any modification of any Secured Obligation, in any
form whatsoever, including without limitation the renewal, extension,
acceleration or other change in time for payment of, or other change in the
terms of, any Secured Obligation or any portion thereof, including increase or
decrease of the rate of interest thereon. Until all Secured Obligations shall
have been paid in full, no Third Party Trustor shall have any right of
subrogation. Each Third Party Trustor waives all rights and defenses it may have
arising out of (1) any election of remedies by Beneficiary, even though that
election of remedies, such as a non-judicial foreclosure with respect to any
security for any portion of the Secured Obligations, destroys such Third Party
Trustor's rights of subrogation or such Third Party Trustor's rights to proceed
against any Obligor for reimbursement, or (2) any loss of rights any Third Party
Trustor may suffer by reason of any rights, powers or remedies of any Obligor in
connection with any anti-deficiency laws or any other laws limiting, qualifying
or discharging any Obligor's obligations, whether by operation of Sections 726
or 580d of the Code of Civil Procedure as from time to time amended, or
otherwise. Until all Secured Obligations shall have been paid in full, each
Third Party Trustor further waives any right to enforce any remedy which
Beneficiary now has or may hereafter have against any Obligor or any other
person, and waives any benefit of, or any right to participate in, any security
now or hereafter held by Beneficiary.

        (iii)  If any of said waivers in this Section 4.18(b) is determined to
be contrary to any applicable law or public policy, such waiver shall be
effective to the extent permitted by law.

            -------                                                       
failure to cure the same within any applicable grace or cure period set forth in
the Credit Agreement or the Notes (or, with respect to the matters set forth in
the following clauses (a) and (b), within the time set forth in the Credit
Agreement for the failure to perform obligations or agreements contained in the
Credit Agreement, or to rectify a misrepresentation) shall constitute a
"Default" under this Deed of Trust:  (a) Trustor shall fail to observe or
perform any obligation or agreement contained herein; (b) any representation or
warranty of Trustor herein shall prove to be incorrect, false or misleading in
any material respect when made; or (c) any default in the payment or performance
of any obligation, or any defined event of default, under any provisions of the
Credit Agreement, any Note, or any other document executed in connection with,
or with respect to, any Secured Obligation.

      5.02  Rights and Remedies.  Upon the occurrence of any Default, and at any
            -------------------                                                 
time thereafter, Beneficiary and Trustee shall have all the following rights and
remedies:

      (a)   With or without notice, to declare all Secured Obligations
immediately due and payable in full;

      (b)   With or without notice, and without releasing Trustor from any
Secured Obligation, and without becoming a mortgagee in possession, to cure any
Default of Trustor and, in connection therewith, to enter upon the Subject
Property and to do such acts and things as Beneficiary or Trustee deems
necessary or desirable to protect the security of this Deed of Trust, including
without limitation, to appear in and defend any action or proceeding purporting
to affect the security of this Deed of Trust or the rights or powers of
Beneficiary or Trustee hereunder; to pay, purchase, contest or compromise any
encumbrance, charge, lien or claim of lien which, in the judgment of either
Beneficiary or Trustee, is senior in priority to this Deed of Trust, the
judgment of Beneficiary or Trustee being conclusive as between the parties
hereto; to obtain, and to pay any premiums or charges with respect to, any
insurance required to be carried hereunder; and to employ counsel, accountants,
contractors and other appropriate persons to assist them;

      (c)   To commence and maintain an action or actions in any court of
competent jurisdiction to foreclose this Deed of Trust as a mortgage or to
obtain specific enforcement of the covenants of Trustor under this Deed of
Trust, and Trustor agrees that such covenants shall be specifically enforceable
by injunction or any other appropriate equitable remedy and that for the
purposes of any suit brought under this subsection, Trustor waives to the extent
permitted by law, the defenses of laches and any applicable statute of
limitations;

      (d)   To apply to a court of competent jurisdiction for and obtain
appointment of a receiver of the Subject Property as a matter of strict right
and without regard to: (i) the adequacy of the security for the repayment of the
Secured Obligations; (ii) the existence of a declaration that the Secured
Obligations are immediately due and payable; or (iii) the filing of a notice of
default; and Trustor consents to such appointment;

      (e) To take and possess all documents, books, records, papers and accounts
of Trustor or the then owner of the Subject Property; to make or modify Leases
of, and other agreements with respect to, the Subject Property upon such terms
and conditions as Beneficiary deems proper; and to make repairs, alterations and
improvements to the Subject Property deemed necessary, in Trustee's or
Beneficiary's judgment, to protect or enhance the security hereof;

      (f)   To execute a written notice of such Default and of its election to
cause the Subject Property to be sold to satisfy the Secured Obligations.
Trustee shall give and record such notice as the law then requires as a
condition precedent to a trustee's sale.  When the minimum period of time
required by law after such notice has elapsed, Trustee, without notice to or
demand upon Trustor, except as otherwise required by law, shall sell the Subject
Property at the time and place of sale fixed by it in the notice of sale, at one
or several sales, either as a whole or in separate parcels and in such manner
and order, all as Beneficiary in its sole discretion may determine, at public
auction to the highest bidder for cash, in lawful money of the United States,
payable at the time of sale (the Secured Obligations being the equivalent of
cash for purposes of said sale).  Neither Trustor nor any other person or entity
shall have the right to direct the order in which the Subject Property is sold.
Subject to requirements and limits imposed by law, Trustee may postpone any sale
of the Subject Property by public announcement at such time and place of sale,
and from time to time may postpone such sale by public announcement at the time
and place fixed by 

                                      -12-
<PAGE>
 
the preceding postponement. Trustee shall deliver to the purchaser at such sale
a deed conveying the Subject Property or portion thereof so sold, but without
any covenant or warranty, express or implied. The recitals in said deed of any
matters or facts shall be conclusive proof of the truthfulness thereof. Any
person, including Trustee, Trustor or Beneficiary, may purchase at such sale;

      (g) To resort to and realize upon the security hereunder and any other
security now or later held by Beneficiary concurrently or successively and in
one or several consolidated or independent judicial actions or lawfully taken
non-judicial proceedings, or both, and to apply the proceeds received to payment
of the Secured Obligations, all in such order and manner as Trustee and
Beneficiary, or either of them, shall determine in their sole discretion, with
the balance (if any) to be paid to the person or persons legally entitled
thereto.

      5.03  Application of Foreclosure Sale Proceeds.  After deducting all
            ----------------------------------------                      
costs, fees and expenses of Trustee, and of this trust, including costs of
evidence of title and reasonable attorneys' fees in connection with a sale,
Trustee shall apply all proceeds of any foreclosure sale first, to payment of
all Secured Obligations (including without limitation, all sums expended by
Beneficiary under the terms hereof and not then repaid, with accrued interest at
the then-current rate per annum payable under any Secured Obligation), in such
order and amounts as Beneficiary in its sole discretion shall determine; and the
remainder, if any, to the person or persons legally entitled thereto.

      5.04  Application of Other Sums.  All Rents or other sums received by
            -------------------------                                      
Beneficiary hereunder, less all costs and expenses incurred by Beneficiary or
any receiver, including reasonable attorneys' fees, shall be applied to payment
of the Secured Obligations in such order as Beneficiary shall determine in its
sole discretion (but Beneficiary shall have no liability for funds not actually
received by Beneficiary), with the balance (if any) to be paid to the person or
persons legally entitled thereto.

      5.05  No Cure or Waiver.  Neither Beneficiary's, Trustee's or any
            -----------------                                          
receiver's entry upon and taking possession of the Subject Property, nor any
collection of Rents, insurance proceeds, condemnation proceeds or damages, other
security or proceeds of other security, or other sums, nor the application of
any collected sum to any Secured Obligation, nor the exercise of any other right
or remedy by Beneficiary, Trustee or any receiver shall impair the status of the
security of this Deed of Trust, or cure or waive any breach, Default or notice
of default under this Deed of Trust, or nullify the effect of any notice of
default or sale (unless all Secured Obligations and any other sums then due
hereunder have been paid in full and Trustor has cured all other Defaults), or
prejudice Beneficiary or Trustee in the exercise of any right or remedy, or be
construed as an affirmation by Beneficiary of any tenancy, lease or option or a
subordination of the lien of this Deed of Trust.

      5.06  Payment of Costs, Expenses and Attorneys' Fees.  Trustor agrees to
            ----------------------------------------------                    
pay to Beneficiary immediately upon demand the full amount of all payments,
advances, charges, costs and expenses, including court costs and reasonable
attorneys' fees (to include outside counsel fees and all allocated costs of
Beneficiary's in-house counsel, whether or not incurred or expended in
litigation), expended or incurred by Trustee or Beneficiary pursuant to
subsections (a) through (g) inclusive of Section 5.02 hereof, with interest from
the date of expenditure until said sums have been paid at the then-current rate
per annum payable under any Secured Obligation.  Beneficiary shall be entitled
to bid, at any sale of the Subject Property held pursuant to Section 5.02(f)
hereof or pursuant to any judicial foreclosure of this Deed of Trust, the amount
of all of the foregoing, including interest thereon, in addition to the amount
of the other Secured Obligations, as a credit bid, the equivalent of cash.

      5.07  Power to File Notices and Cure Defaults.  Trustor hereby irrevocably
            ---------------------------------------                             
appoints Beneficiary and its successors and assigns as Trustor's true attorney-
in-fact to perform any of the following powers, which agency is coupled with an
interest, (a) to execute and/or record any notices of completion, cessation of
labor, or any other notices that Beneficiary reasonably deems appropriate to
protect Beneficiary's interest, and (b) upon the occurrence of any event, act or
omission which with the giving of notice or the passage of time, or both, would
constitute a Default, to perform any obligation of Trustor hereunder; provided
that:  (i) Beneficiary, as such attorney-in-fact, shall only be accountable for
such funds as are actually received by Beneficiary; and (ii) Beneficiary shall
not be liable to Trustor or any other person or entity for any failure to act
under this Section.

      5.08  Remedies Cumulative.  All rights and remedies of Beneficiary and
            -------------------                                             
Trustee hereunder are cumulative and are in addition to all rights and remedies
provided by law or in any other agreements between Trustor and Beneficiary.

undertakings owing by Borrower to Secured Party of any kind or description
arising out of or outstanding under, advanced or issued pursuant to, or
evidenced by the Credit Agreement, the other Loan Documents, or this Agreement,
irrespective of whether for the payment of money, whether direct or indirect,

     (b)  Construction.
          ------------ 

            (i) Unless the context of this Agreement clearly requires otherwise,
references to the plural include the singular and to the singular include the
plural, the part includes the whole, the term "including" is not limiting, and
the term "or" has, except where otherwise indicated, the inclusive meaning
represented by the 

                                       3
<PAGE>
 
phrase "and/or." The words "hereof," "herein," "hereby," "hereunder," and other
similar terms in this Agreement refer to this Agreement as a whole and not
exclusively to any particular provision of this Agreement. Article, section,
subsection, exhibit, and schedule references are to this Agreement unless
otherwise specified. All of the exhibits or schedules attached to this Agreement
shall be deemed incorporated herein by reference. Any reference to any of the
following documents includes any and all alterations, amendments, restatements,
extensions, modifications, renewals, or supplements thereto or thereof, as
applicable: this Agreement, the Credit Agreement, or any of the other Loan
Documents.

          (ii)  Neither this Agreement nor any uncertainty or ambiguity herein
shall be construed or resolved against Secured Party or Pledgor, whether under
any rule of construction or otherwise.  On the contrary, this Agreement has been
reviewed by both of the parties and their respective counsel and shall be
construed and interpreted according to the ordinary meaning of the words used so
as to fairly accomplish the purposes and intentions of the parties hereto.

          (iii) In the event of a direct conflict between the terms and
provisions of this Agreement, on the one hand, and the Credit Agreement or the
Security Agreement to which Pledgor is a party (the "Pledgor Security
Agreement"), on the other hand, it is the intention of the parties hereto that
both such documents shall be read together and construed, to the fullest extent
possible, to be in concert with each other. In the event of any actual,
irreconcilable conflict that cannot be resolved as aforesaid, the terms and
provisions of the Credit Agreement or the Pledgor Security Agreement, as the
case may be, shall control and govern; provided, however, that the inclusion
herein of additional obligations on the part of Pledgor and supplemental rights
and remedies in favor of Secured Party, in each case in respect of the
Collateral, shall not be deemed a conflict with the Credit Agreement or the
Pledgor Security Agreement, as the case may be.

     2.   Pledge.  As security for the prompt payment and performance of
          ------                                                        
the Secured Obligations in full by Borrower when due, whether at stated
maturity, by acceleration or otherwise (including amounts that would become due
but for the operation of the provisions of the Bankruptcy Code), Pledgor hereby
pledges, grants, transfers, and assigns to Secured Party a security interest in
all of Pledgor's right, title, and interest in and to the Collateral.

     3.  Delivery and Registration of Collateral.
         --------------------------------------- 

         (a) All certificates or instruments representing or evidencing the
Collateral shall be promptly delivered by Pledgor to Secured Party or Secured
Party's designee pursuant hereto at a location designated by Secured Party and
shall be held by or on behalf of Secured Party pursuant hereto, and shall be in
suitable form for transfer by delivery, or shall be accompanied by duly executed
instruments of transfer or assignment in blank, all in form and substance
satisfactory to Secured Party.

<PAGE>
 
          (b) After the occurrence and during the continuance of an Event of
Default, Secured Party shall have the right, at any time in its discretion and
without notice to Pledgor, to transfer to or to register on the books of the
Issuers (or of any other Person maintaining records with respect to the
Collateral) in the name of Secured Party or any of its nominees any or all of
the Collateral.  In addition, Secured Party shall have the right at any time to
exchange certificates or instruments representing or evidencing Collateral for
certificates or instruments of smaller or larger denominations.

          (c) If, at any time and from time to time, any Collateral (including
any certificate or instrument representing or evidencing any Collateral) is in
the possession of a Person other than Secured Party or Pledgor (a "Holder"),
then Pledgor shall immediately, at Secured Party's option, either cause such
Collateral to be delivered into Secured Party's possession, or execute and
deliver to such Holder a written notification/instruction, and take all other
steps necessary to perfect the security interest of Secured Party in such
Collateral, including obtaining from such Holder a written acknowledgement that
such Holder holds such Collateral for Secured Party, all pursuant to (S)(S)8-313
and 8-321 of the Code or other applicable law governing the perfection of
Secured Party's security interest in the Collateral in the possession of such
Holder.  Each such notification/instruction and acknowledgement shall be in form
and substance satisfactory to Secured Party.

          (d) Any and all Collateral (including dividends, interest, and other
cash distributions) at any time received or held by Pledgor shall be so received
or held in trust for Secured Party, shall be segregated from other funds and
property of Pledgor and shall be forthwith delivered to Secured Party in the
same form as so received or held, with any necessary endorsements; provided that
                                                                   --------     
cash dividends or distributions received by Pledgor, if and to the extent they
are not prohibited by the Credit Agreement, may be retained by Pledgor in
accordance with Section 4 and used in the ordinary course of Pledgor's business.
                ---------                                                       

          (e) If at any time and from time to time any Collateral consists of an
uncertificated security or a security in book entry form, then Pledgor shall
immediately cause such Collateral to be registered or entered, as the case may
be, in the name of Secured Party, or otherwise cause Secured Party's security
interest thereon to be perfected in accordance with applicable law.

     4.   Voting Rights and Dividends.
          --------------------------- 

          (a) So long as no Event of Default shall have occurred and be
continuing, Pledgor shall be entitled to exercise any and all voting and other
consensual rights pertaining to the Collateral or any part thereof for any
purpose not inconsistent with the terms of the Loan Documents and shall be
entitled to receive and retain any cash dividends or distributions paid in
respect of the Collateral.

                                       5
<PAGE>
 
          (b) Upon the occurrence and during the continuance of an Event of
Default (and, with respect to voting rights only, after the receipt of written
nottice from Secured Party), all rights of Pledgor to exercise the voting and
other consensual rights or receive and retain cash dividends or distributions
that it would otherwise be entitled to exercise or receive and retain, as
applicable pursuant to Section 4(a), shall cease, and all such rights shall
                       -----------                                         
thereupon become vested in Secured Party, who shall thereupon have the sole
right to exercise such voting or other consensual rights and to receive and
retain such cash dividends and distributions.  Pledgor shall execute and deliver
(or cause to be executed and delivered) to Secured Party all such proxies and
other instruments as Secured Party may reasonably request for the purpose of
enabling Secured Party to exercise the voting and other rights which it is
entitled to exercise and to receive the dividends and distributions that it is
entitled to receive and retain pursuant to the preceding sentence.

     5.   Representations and Warranties.  Pledgor represents, warrants,

          (a) Pledgor has taken all steps it deems necessary or appropriate to
be informed on a continuing basis of changes or potential changes affecting the
Collateral (including rights of conversion and exchange, rights to subscribe,
payment of dividends, reorganizations or recapitalization, tender offers and
voting rights), and Pledgor agrees that Secured Party shall have no
responsibility or liability for informing Pledgor of any such changes or
potential changes or for taking any action or omitting to take any action with
respect thereto;

          (b) All information herein or hereafter supplied to Secured Party by
or on behalf of Pledgor in writing with respect to the Collateral is, or in the
case of information hereafter supplied will be, accurate and complete in all

          (c) Pledgor is and will be the sole legal and beneficial owner of the
Collateral (including the Pledged Shares and all other Collateral acquired by
Pledgor after the date hereof) free and clear of any adverse claim, Lien, or
other right, title, or interest of any party;

          (d) To Pledgor's knowledge, this Agreement, and the delivery to
Secured Party of the Pledged Shares representing Collateral (or the delivery to
all Holders of the Pledged Shares representing Collateral of the
notification/instruction referred to in Section 3 of this Agreement), creates a
                                        ---------

all material respects; without limiting the generality of the foregoing: (i) all
the Pledged Shares are in certificated form, and, except to the extent
registered in the name of Secured 

                                       6
<PAGE>
 
Party or its nominee pursuant to the provisions of this Agreement, are
registered in the name of Pledgor; and (ii) the Pledged Shares as to each of the
Issuers constitute at least the percentage of all the fully diluted issued and
outstanding shares of stock of such Issuer as set forth in Schedule A to this 
                                                           ----------
Agreement;

          (f) There are no presently existing Future Rights or Proceeds owned by
Pledgor, except as set forth in Schedule C hereto;
                                ----------        

          (g) The Pledged Shares have been duly authorized and validly

     6.   Further Assurances.
          ------------------ 

          (a) Pledgor agrees that from time to time, at the expense of Pledgor,
Pledgor will promptly execute and deliver all further instruments and documents,
and take all further action that may be necessary or reasonably desirable, or
that Secured Party may request, in order to perfect and protect any security
interest granted or purported to be granted hereby or to enable Secured Party to
exercise and enforce its rights and remedies hereunder with respect to any
Collateral. Without limiting the generality of the foregoing, Pledgor will: (i)
at the request of Secured Party, mark conspicuously each of its records
pertaining to the Collateral with a legend, in form and substance reasonably
satisfactory to Secured Party, indicating that such Collateral is subject to the
security interest granted hereby; (ii) execute and file such financing or
continuation statements, or amendments thereto, and such other instruments or
notices, as may be necessary or reasonably desirable, or as Secured Party may
request, in order to perfect and preserve the security interests granted or
purported to be granted hereby; (iii) allow inspection of the Collateral by
Secured Party or Persons designated by Secured Party; and (iv) appear in and
defend any action or proceeding that may affect Pledgor's title to or Secured
Party's security interest in the Collateral.

          (b) Pledgor hereby authorizes Secured Party to file one or more
financing or continuation statements, and amendments thereto, relative to all or
any part of the Collateral without the signature of Pledgor where permitted by
law. A carbon, photographic, or other reproduction of this Agreement or any
financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.

          (c) Pledgor will furnish to Secured Party, upon the request of Secured
Party: (i) a certificate executed by an authorized officer of Pledgor, and dated
as of the date of delivery to Secured Party, itemizing in such detail as Secured

request, the Collateral which, as of the date of such certificate, has
been delivered to Secured Party by Pledgor pursuant to the provisions of this
Agreement; and (ii) such statements and schedules further identifying and
describing the Collateral and such other reports in connection with the
Collateral as Secured Party may request.

     7.   Covenants of Pledgor.  Pledgor shall:
          --------------------                 

          (a) Perform each and every covenant in the Loan Documents
applicable to Pledgor;

          (b) At all times keep at least one complete set of its records
concerning substantially all of the Collateral at its Chief Executive Office as
set forth in Schedule B hereto, and not change the location of its Chief
             ----------                                                 
Executive Office or such records without giving Secured Party at least thirty
(30) days prior written notice thereof;

          (c) To the extent it may lawfully do so, use its best efforts to
prevent the Issuers from issuing Future Rights or Proceeds, except for cash
dividends and other distributions, if any, that are not prohibited by the terms
of the Credit Agreement to be paid by any Issuer to Pledgor; and

          (d) Upon receipt by Pledgor of any material notice, report, or other
communication from any of the Issuers or any Holder relating to all or any part
of the Collateral, deliver such notice, report or other communication to Secured
Party as soon as possible, but in no event later than five (5) days following
the receipt thereof by Pledgor.

     8.   Secured Party as Pledgor's Attorney-in-Fact.
          ------------------------------------------- 

          (a) Pledgor hereby irrevocably appoints Secured Party as Pledgor's
attorney-in-fact, with full authority in the place and stead of Pledgor and in
the name of Pledgor, Secured Party or otherwise, from time to time at Secured
Party's discretion, to take any action and to execute any instrument that
Secured Party may reasonably deem necessary or advisable to accomplish the
purposes of this Agreement, including: (i) after the occurrence and during the
continuance of an Event of Default, to receive, endorse, and collect all
instruments made payable to Pledgor representing any dividend, interest payment
or other distribution in respect of the Collateral or any part thereof to the
extent permitted hereunder and to give full discharge for the same and to
execute and file governmental notifications and reporting forms; (ii) to issue
any notifications/instructions Secured Party deems necessary pursuant to Section
                                                                         -------
3 of this Agreement; or (iii) to arrange for the transfer of the Collateral on
- - -                                                                             
the books of any of the Issuers or any other Person to the name of Secured Party
or to the name of Secured Party's nominee.

          (b) In addition to the designation of Secured Party as Pledgor's
attorney-in-fact in subsection (a), Pledgor hereby irrevocably appoints Secured
                    --------------                                             
Party as Pledgor's agent and attorney-in-fact to make, execute and deliver any
and all documents 

                                       8
<PAGE>
 
and writings which may be necessary or appropriate for approval of, or be
required by, any regulatory authority located in any city, county, state or
country where Pledgor or any of the Issuers engage in business, in order to
transfer or to more effectively transfer any of the Pledged Shares or otherwise
enforce Secured Party's rights hereunder.

     9.   Remedies upon Default.  Upon the occurrence and during the
          ---------------------                                     
continuance of an Event of Default:

          (a) Secured Party may exercise in respect of the Collateral, in
addition to other rights and remedies provided for herein or otherwise available
to it, all the rights and remedies of a secured party on default under the Code
(irrespective of whether the Code applies to the affected items of Collateral),
and Secured Party may also without notice (except as specified below) sell the
Collateral or any part thereof in one or more parcels at public or private sale,
at any exchange, broker's board or at any of Secured Party's offices or
elsewhere, for cash, on credit or for future delivery, at such time or times and
at such price or prices and upon such other terms as Secured Party may deem
commercially reasonable, irrespective of the impact of any such sales on the
market price of the Collateral. To the maximum extent permitted by applicable
law, Secured Party may be the purchaser of any or all of the Collateral at any
such sale and shall be entitled, for the purpose of bidding and making
settlement or payment of the purchase price for all or any portion of the
Collateral sold at any such public sale, to use and apply all or any part of the
Secured Obligations as a credit on account of the purchase price of any
Collateral payable at such sale.  Each purchaser at any such sale shall hold the
property sold absolutely free from any claim or right on the part of Pledgor,
and Pledgor hereby waives (to the extent permitted by law) all rights of
redemption, stay, or appraisal that it now has or may at any time in the future
have under any rule of law or statute now existing or hereafter enacted.
Pledgor agrees that, to the extent notice of sale shall be required by law, at
least ten (10) calendar days notice to Pledgor of the time and place of any
public sale or the time after which a private sale is to be made shall
constitute reasonable notification.  Secured Party shall not be obligated to
make any sale of Collateral regardless of notice of sale having been given.
Secured Party may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned. To
the maximum extent permitted by law, Pledgor hereby waives any claims against
Secured Party arising because the price at which any Collateral may have been
sold at such a private sale was less than the price that might have been
obtained at a public sale, even if Secured Party accepts the first offer
received and does not offer such Collateral to more than one offeree.

          (b) Pledgor hereby agrees that any sale or other disposition of the
Collateral conducted in conformity with reasonable commercial practices of
banks, insurance companies, or other financial institutions in the City of Los
Angeles, California in disposing of property similar to the Collateral shall be
deemed to be commercially reasonable.

                                       9
<PAGE>
 
          (c) Pledgor hereby acknowledges that the sale by Secured Party of any
Collateral pursuant to the terms hereof in compliance with the Securities Act of
1933 as now in effect or as hereafter amended, or any similar statute hereafter
adopted with similar purpose or effect (the "Securities Act"), as well as
applicable "Blue Sky" or other state securities laws may require strict
limitations as to the manner in which Secured Party or any subsequent transferee
of the Collateral may dispose thereof.  Pledgor acknowledges and agrees that in
order to protect Secured Party's interest it may be necessary to sell the
Collateral at a price less than the maximum price attainable if a sale were
delayed or were made in another manner, such as a public offering under the
Securities Act.  Pledgor has no objection to sale in such a manner and agrees
that Secured Party shall have no obligation to obtain the maximum possible price
for the Collateral.  Anything herein to the contrary notwithstanding, Pledgor
agrees that (i) upon the occurrence and during the continuation of an Event of
Default, Secured Party may, subject to applicable law, from time to time elect
(but shall have no obligation) to conduct the offer and sale of all or any part
of the Collateral in such a manner as to avoid the need for registration or
qualification thereof under any federal or state securities laws, such as by a
private placement, (ii) such conduct may include restrictions and other
requirements that may result in prices or other terms less favorable than those
which might have been obtained through a public sale not subject to such
restrictions and requirements, including, without limitation, restricting the
bidders and prospective purchasers to those who will represent and agree that
they are purchasing for their own account, for investment only, and not with a
view towards distribution or resale, (iii) in so doing, Secured Party may
solicit offers to buy the Collateral or any part thereof for cash, from a
limited number of investors deemed by Secured Party, in its reasonable judgment,
to be institutional investors or other responsible parties who might be
interested in purchasing the Collateral, and (iv) any offer and sale so
conducted shall be deemed to be a commercially reasonable method of disposition
of the Collateral.

          (d) If Secured Party shall determine to exercise its right to sell all
or any portion of the Collateral pursuant to this Section, Pledgor agrees that,
upon request of Secured Party, Pledgor will, at its own expense:

               (i) use its best efforts to execute and deliver, and cause the
Issuers and the directors and officers thereof to execute and deliver, all such
instruments and documents, and to do or cause to be done all such other acts and
things, as may be necessary or, in the opinion of Secured Party, advisable to
register such Collateral under the provisions of the Securities Act, and to
cause the registration statement relating thereto to become effective and to
remain effective for such period as prospectuses are required by law to be
furnished, and to make all amendments and supplements thereto and to the related
prospectuses which, in the opinion of Secured Party, are necessary or advisable,
all in conformity with the requirements of the Securities Act and the rules and
regulations of the Securities and Exchange Commission applicable thereto;

                                       10

               (ii)   use its best efforts to qualify the Collateral under the
state securities laws or "Blue Sky" laws and to obtain all necessary
governmental approvals for the sale of the Collateral, as requested by Secured
Party;

               (iii)  cause the Issuers to make available to their respective
security holders, as soon as practicable, an earnings statement which will
satisfy the provisions of Section 11(a) of the Securities Act;

               (iv)   execute and deliver, or cause the officers and directors
of the Issuers to execute and deliver, to any person, entity or governmental
authority as Secured Party may choose, any and all documents and writings which,
in Secured Party's reasonable judgment, may be necessary or appropriate for
approval, or be required by, any regulatory authority located in any city,
county, state or country where Pledgor or the Issuers engage in business, in
order to transfer or to more effectively transfer the Pledged Shares or
otherwise enforce Secured Party's rights hereunder; and

               (v)    do or cause to be done all such other acts and things as
may be necessary to make such sale of the Collateral or any part thereof valid
and binding and in compliance with applicable law.

Pledgor acknowledges that there is no adequate remedy at law for failure by it
to comply with the provisions of this Section and that such failure would not be
adequately compensable in damages, and therefore agrees that its agreements
contained in this Section may be specifically enforced.

          (e) PLEDGOR EXPRESSLY WAIVES TO THE MAXIMUM EXTENT PERMITTED BY LAW:
(i) ANY CONSTITUTIONAL OR OTHER RIGHT TO A JUDICIAL HEARING PRIOR TO THE TIME
SECURED PARTY DISPOSES OF ALL OR ANY PART OF THE COLLATERAL AS PROVIDED IN THIS

continuance of an Event of Default, any cash held by Secured Party as Collateral
and all cash proceeds received by Secured Party in respect of any sale of,
collection from, or other realization upon all or any part of the Collateral
pursuant to the exercise by Secured Party of its remedies as a secured creditor
as provided in Section 9 shall be applied from time to time by Secured Party as
               ---------                                                       
provided in the Credit Agreement.

          -----------------------                                        
hereunder are solely to protect its interests in the Collateral and shall not
impose on it any 

                                       11

Persons with respect to any Collateral.

     12.  Choice of Law and Venue.  THE VALIDITY OF THIS AGREEMENT, ITS
          -----------------------                                      
CONSTRUCTION, INTERPRETATION, AND ENFORCEMENT, AND THE RIGHTS OF THE PARTIES
HERETO SHALL BE DETERMINED UNDER, GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF CALIFORNIA.  THE PARTIES AGREE THAT ALL ACTIONS OR

OTHER COURT IN WHICH SECURED PARTY SHALL INITIATE LEGAL OR EQUITABLE PROCEEDINGS
AND WHICH HAS SUBJECT MATTER JURISDICTION OVER THE MATTER IN CONTROVERSY.  EACH
OF PLEDGOR AND SECURED PARTY WAIVES, TO THE EXTENT PERMITTED UNDER APPLICABLE
LAW, ANY RIGHT EACH MAY HAVE TO ASSERT THE DOCTRINE OF FORUM NON CONVENIENS OR
TO OBJECT TO VENUE TO THE EXTENT ANY PROCEEDING IS BROUGHT IN ACCORDANCE WITH

     ---------- 

     13.  Amendments; Etc.  No amendment or waiver of any provision of this
          ---------------                                                  
Agreement nor consent to any departure by Pledgor herefrom shall in any event be
effective unless the same shall be in writing and signed by Secured Party, and
then such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given.  No failure on the part of Secured
Party to exercise, and no delay in exercising any right under this Agreement,
any other Loan Document, or otherwise with respect to any of the Secured
Obligations, shall operate as a waiver thereof; nor shall any single or partial
exercise of any right under this Agreement, any other Loan Document, or
otherwise with respect to any of the Secured Obligations preclude any other or
further exercise thereof or the exercise of any other right.  The remedies
provided for in this Agreement or otherwise with respect to any of the Secured
Obligations are cumulative and not exclusive of any remedies provided by law.

     14.  Notices.  Unless otherwise specifically provided herein, any
          -------                                                     
notice or other communication herein required or permitted to be given shall be
in writing and shall be delivered in the manner set forth in the Credit
Agreement.

     15.  Continuing Security Interest.  This Agreement shall create a
          ----------------------------                                
continuing security interest in the Collateral and shall: (i) remain in full
force and effect until the indefeasible payment in full of the Secured
Obligations, including the cash collateralization, expiration, or cancellation
of all Secured Obligations, if any, consisting of letters of credit, and the
full and final termination of any commitment to extend any financial

                                       12
<PAGE>
 
accommodations under the Credit Agreement; (ii) be binding upon Pledgor and its
successors and assigns; and (iii) inure to the benefit of Secured Party and its
successors, transferees, and assigns.  Upon the indefeasible payment in full of
the Secured Obligations, including the cash collateralization, expiration, or
cancellation of all Secured Obligations, if any, consisting of letters of
credit, and the full and final termination of any commitment to extend any
financial accommodations under the Credit Agreement, the security interests
granted herein shall automatically terminate and all rights to the Collateral
shall revert to Pledgor.  Upon any such termination, Secured Party will, at
Pledgor's expense, execute and deliver to Pledgor such documents as Pledgor
shall reasonably request to evidence such termination.  Such documents shall be
prepared by Pledgor and shall be in form and substance reasonably satisfactory
to Secured Party.

     16.  Security Interest Absolute.  To the maximum extent permitted by
          --------------------------                                     
law, all rights of Secured Party, all security interests hereunder, and all
obligations of Pledgor hereunder, shall be absolute and unconditional
irrespective of:

          (a) any lack of validity or enforceability of any of the Secured
Obligations or any other agreement or instrument relating thereto, including any
of the Loan Documents;

          (b) any change in the time, manner, or place of payment of, or in any
other term of, all or any of the Secured Obligations, or any other amendment or
waiver of or any consent to any departure from any of the Loan Documents, or any
other agreement or instrument relating thereto;

          (c) any exchange, release, or non-perfection of any other collateral,
or any release or amendment or waiver of or consent to departure from any
guaranty for all or any of the Secured Obligations; or

          (d) any other circumstances that might otherwise constitute a
defense available to, or a discharge of, Pledgor.

To the maximum extent permitted by law, Pledgor hereby waives any right to
require Secured Party to: (A) proceed against or exhaust any security held from
Pledgor; or (B) pursue any other remedy in Secured Party's power whatsoever.

     17.  Headings.  Section and subsection headings in this Agreement are
          --------                                                        
included herein for convenience of reference only and shall not constitute a
part of this Agreement or be given any substantive effect.

     18.  Severability.  In case any provision in or obligation under this
          ------------                                                    
Agreement shall be invalid, illegal or unenforceable in any jurisdiction, the
validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

                                       13
<PAGE>
 
     19.  Counterparts.  This Agreement may be executed in one or more
          ------------                                                
counterparts, each of which shall be deemed an original and all of which
together shall constitute one and the same Agreement.

     20.  Waiver of Marshaling.  Each of Pledgor and Secured Party
          --------------------                                    
acknowledges and agrees that in exercising any rights under or with respect to
the Collateral: (i) Secured Party is under no obligation to marshal any
Collateral; (ii) may, in its absolute discretion, realize upon the Collateral in
any order and in any manner it so elects; and (iii) may, in its absolute
discretion, apply the proceeds of any or all of the Collateral to the Secured
Obligations in any order and in any manner it so elects.  Pledgor and Secured
Party waive any right to require the marshaling of any of the Collateral.

     21.  Waiver of Jury Trial.  PLEDGOR AND SECURED PARTY HEREBY WAIVE
          --------------------                                         
THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED
UPON OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED
HEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL
OTHER COMMON LAW OR STATUTORY CLAIMS. PLEDGOR AND SECURED PARTY REPRESENT THAT
EACH HAS REVIEWED THIS WAIVER AND EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY
TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. IN THE EVENT OF
LITIGATION, A COPY OF THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A
TRIAL BY THE COURT.

     22.  Waivers.
          ------- 

          (a) To the maximum extent permitted by law, Pledgor hereby waives: (i)
notice of acceptance hereof; (ii) notice of any loans or other financial
accommodations made or extended under the Credit Agreement, or the creation or
existence of any Indebtedness; (iii) notice of the amount of the Indebtedness,
subject, however, to Section 6.2 of the Credit Agreement and Pledgor's right to
make inquiry of Secured Party to ascertain the amount of the Indebtedness at any
reasonable time; (iv) notice of any adverse change in the financial condition of
Borrower or of any other fact that might increase Pledgor's risk hereunder; (v)
notice of presentment for payment, demand, protest, and notice thereof as to any
instrument among the Loan Documents; (vi) notice of any unmatured Event of
Default or Event of Default under the Credit Agreement; and (vii) all other
notices (except if such notice is specifically required to be given to Pledgor
under this Agreement) and demands to which Pledgor might otherwise be entitled.

          (b) To the fullest extent permitted by applicable law, Pledgor waives
the right by statute or otherwise to require Secured Party to institute suit
against Borrower or to exhaust any rights and remedies which Secured Party has
or may have against Borrower. Pledgor further waives any defense arising by
reason of any disability or other defense (other than the defense that the
Indebtedness shall have been fully and finally indefeasibly 

                                       14
<PAGE>
 
paid) of Borrower or by reason of the cessation from any cause (other than that
the Indebtedness shall have been fully and finally indefeasibly paid) whatsoever
of the liability of Borrower in respect thereof.

          (c) To the maximum extent permitted by law, Pledgor hereby waives: (i)
any rights to assert against Secured Party any defense (legal or equitable),
set-off, counterclaim, or claim which Pledgor may now or at any time hereafter
have against Borrower or any other party liable to Secured Party on account of
or with respect to the Indebtedness; (ii) any defense, set-off, counterclaim, or
claim, of any kind or nature, arising directly or indirectly from the present or
future sufficiency, validity, or enforceability of the Indebtedness; (iii) any
defense arising by reason of any claim or defense based upon an election of
remedies by Secured Party including, to the extent applicable, the provisions of
(S)(S) 580d and 726 of the California Code of Civil Procedure, or any similar
law of California or any other jurisdiction; (iv) the benefit of any statute of
limitations affecting Pledgor's liability hereunder or the enforcement thereof.

          (d) To the maximum extent permitted by law, Pledgor hereby waives and
postpones until indefeasible payment in full of the Indebtedness any right of
subrogation Pledgor has or may have as against Borrower with respect to the
Indebtedness.  In addition, Pledgor hereby waives and postpones until
indefeasible payment in full of the Indebtedness any right to proceed against
Borrower, now or hereafter, for contribution, indemnity, reimbursement, or any
other suretyship rights and claims (irrespective of whether direct or indirect,
liquidated or contingent), with respect to the Indebtedness.  Pledgor also
hereby waives and postpones until indefeasible payment in full of the
Indebtedness any right to proceed or to seek recourse against or with respect to
any property or asset of Borrower. Pledgor hereby agrees that, in light of the
waivers and postponements of rights contained in this Section, Pledgor shall not
be deemed to be a "creditor" (as that term is defined in the Bankruptcy Code or
otherwise) of Borrower, whether for purposes of the application of Sections 547
or 550 of the United States Bankruptcy Code or otherwise.

          (e) If any of the Secured Obligations at any time are secured by a
mortgage or deed of trust upon real property, Secured Party may elect, in its
sole discretion, upon a default with respect to the Secured Obligations, to
foreclose such mortgage or deed of trust judicially or nonjudicially in any
manner permitted by law, before or after enforcing this Agreement, without
diminishing or affecting the liability of Pledgor hereunder.  Pledgor
understands that (a) by virtue of the operation of California's antideficiency
law applicable to nonjudicial foreclosures, an election by Secured Party
nonjudicially to foreclose such a mortgage or deed of trust probably would have
the effect of impairing or destroying rights of subrogation, reimbursement,
contribution, or indemnity of Pledgor against Borrower or guarantors or
sureties, and (b) absent the waiver and postponement of rights given by Pledgor
herein, such an election might estop Secured Party from enforcing this Agreement
against Pledgor.  Understanding the foregoing, and understanding that Pledgor is
hereby relinquishing a defense to the enforceability of this Agreement, Pledgor
hereby waives any right to assert against Secured Party any defense 

                                       15
<PAGE>
 
to the enforcement of this Agreement, whether denominated "estoppel" or
otherwise, based on or arising from an election by Secured Party nonjudicially
to foreclose any such mortgage or deed of trust. Pledgor understands that the
effect of the foregoing waiver may be that Pledgor may have liability hereunder
for amounts with respect to which Pledgor may be left without rights of
subrogation, reimbursement, contribution, or indemnity against Borrower or
guarantors or sureties. Pledgor also agrees that the "fair market value"
provisions of Section 580a of the California Code of Civil Procedure shall have
no applicability with respect to the determination of Pledgor's liability under
this Agreement.

          (f) WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER
PROVISION SET FORTH IN THIS AGREEMENT, PLEDGOR HEREBY WAIVES, TO THE MAXIMUM
EXTENT SUCH WAIVER IS PERMITTED BY LAW, ANY AND ALL DEFENSES ARISING DIRECTLY OR
INDIRECTLY UNDER ANY ONE OR MORE OF CALIFORNIA CIVIL CODE (S)(S) 2808, 2809,
2810, 2815, 2819, 2820, 2821, 2838, 2839, 2845, 2848, 2849, AND 2850, TO THE
EXTENT APPLICABLE, CALIFORNIA CODE OF CIVIL PROCEDURE (S)(S) 580a, 580b, 580c,
580d, AND 726, AND, TO THE EXTENT APPLICABLE, CHAPTER 2 OF TITLE 14 OF THE
CALIFORNIA CIVIL CODE.

          (g)  WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER
PROVISION SET FORTH IN THIS AGREEMENT, PLEDGOR HEREBY WAIVES ALL RIGHTS AND
DEFENSES ARISING OUT OF AN ELECTION OF REMEDIES BY SECURED PARTY, EVEN THOUGH
THAT ELECTION OF REMEDIES, SUCH AS A NONJUDICIAL FORECLOSURE WITH RESPECT TO
SECURITY FOR A SECURED OBLIGATION, HAS DESTROYED PLEDGOR'S RIGHTS OF SUBROGATION
AND REIMBURSEMENT AGAINST THE PRINCIPAL BY THE OPERATION OF SECTION 580d OF THE
CODE OF CIVIL PROCEDURE OR OTHERWISE.


          IN WITNESS WHEREOF, Pledgor and Secured Party have caused this
Agreement to be duly executed and delivered by their officers thereunto duly
authorized as of the date first written above.

                           PATENT SECURITY AGREEMENT
                           -------------------------

          THIS PATENT SECURITY AGREEMENT (this "Agreement"), dated as of
February 15, 1996 is made by each of MDT CORPORATION, a Delaware corporation
("MDT"), MDT BIOLOGIC COMPANY, a Delaware corporation ("Biologic"), MDT
DIAGNOSTIC COMPANY, a Delaware corporation ("Diagnostic"), MDT CANADA LIMITED, a
corporation incorporated under the laws of the Province of Ontario ("Canada"),
and MDT TECHNIONIC COMPANY, a Delaware corporation ("Technionic") (individually,
a "Debtor", and collectively, the "Debtors"), in favor of WELLS FARGO BANK,
NATIONAL ASSOCIATION, as agent under the below-referenced Credit Agreement
("Secured Party").

                                   RECITALS
                                   --------

          A.  The Debtors and Secured Party are parties to the Credit Agreement,
pursuant to which the Banks agreed to make certain financial accommodations to
the Debtors.  In addition, each Debtor is party to a Security Agreement,
pursuant to which, such Debtor has granted to Secured Party a security interest
in (among other things) all of the general intangibles of such Debtor.

          B.  Pursuant to the February 15, 1996 Amendment, and as one of the
conditions precedent to the obligations of the Banks thereunder, each Debtor has
agreed to execute and deliver this Agreement to Secured Party for filing with
the United States Patent and Trademark Office and with any other relevant
recording systems in any domestic or foreign jurisdiction, and as further
evidence of and to effectuate Secured Party's existing security interests in the
patents and other general intangibles described herein.

                                   AGREEMENT
                                   ---------

specific Section, subsection, paragraph or clause in which the respective word

infringement, misappropriation or violation thereof by others and for that

documents or agreements in exchange for or relative to any of the Loan Documents
or the Secured Obligations or any part thereof; (d) accept partial payments on
the Secured Obligations; (e) receive and hold additional security or guarantees
for the Secured Obligations or any part thereof; (f) release, reconvey,
terminate, waive, abandon, fail to perfect, subordinate, exchange, substitute,
transfer or enforce any security or guarantees, and apply any security and
direct the order or manner of sale thereof as Secured Party in its sole and
absolute discretion may determine; (g) release any Person from any personal
liability with respect to the Secured Obligations or any part thereof; (h)
settle, release on terms satisfactory to Secured Party or by operation of
applicable laws or otherwise liquidate or enforce any Secured Obligations and
any security therefor or guaranty thereof in any manner, consent to the transfer
of any security and bid and purchase at any sale; or (i) consent to the merger,
change or any other restructuring or termination of the corporate or partnership
existence of any Debtor or any other Person, and correspondingly restructure the
Secured Obligations, and any such merger, change, restructuring or termination
shall not affect the liability of any Debtor or the continuing effectiveness
hereof, or the enforceability hereof with respect to all or any part of the
Secured Obligations.

        Upon the occurrence and during the continuance of any Event of Default,
Secured Party may enforce this Agreement independently as to each Debtor and
independently of any other remedy or security Secured Party at any time may have
or hold in connection with the Secured Obligations, and it shall not be
necessary for Secured Party to marshal assets in favor of any Debtor or any
other Person or to proceed upon or against or exhaust any security or remedy
before proceeding to enforce this Agreement.  Each Debtor expressly waives any
right to require Secured Party to marshal assets in favor of any Debtor or any
other Person or to proceed against any other Debtor or any collateral provided
by any Person, and agrees that Secured Party may proceed against Debtors or any
collateral in such order as it shall determine in its sole and absolute
discretion.

        Secured Party may file a separate action or actions against any Debtor,
whether action is brought or prosecuted with respect to any security or against
any other Person, or whether any other Person is joined in any such action or
actions.  Each Debtor agrees that Secured Party and any Debtor and any Affiliate
of any Debtor may deal with each other in connection with the Secured
Obligations or otherwise, or alter any contracts or agreements now or hereafter
existing between any of them, in any manner whatsoever, all without in any way
altering or affecting the continuing efficacy of this Agreement.

         Secured Party's rights hereunder shall be reinstated and revived, and
the enforceability of this Agreement shall continue, with respect to any amount
at any time paid on account of the Secured Obligations which thereafter shall be
required to be restored or returned by Secured Party, all as though such amount
had not been paid. The rights of Secured Party created or granted herein and the
enforceability of this Agreement at all times shall remain effective to cover
the full amount of all the Secured Obligations even though the Secured
Obligations, including any part thereof or any other security or guaranty
therefor, may be or hereafter may become invalid or otherwise unenforceable as
against any Debtor and whether or not any other Debtor shall have any personal
liability with respect thereto.

          To the maximum extent permitted by applicable law, each Debtor
expressly waives any and all defenses now or hereafter arising or asserted by
reason of (a) any disability or other defense of any other Debtor with respect
to the Secured Obligations, (b) the unenforceability or invalidity of any
security or guaranty for the Secured Obligations or the lack of perfection or
continuing perfection or failure of priority of any security for the Secured
Obligations, (c) the cessation for any cause whatsoever of the liability of any
other Debtor (other than by reason of the full payment and performance of all
Secured Obligations), (d) any failure of Secured Party to marshal assets in
favor of any Debtor or any other Person, (e) any failure of Secured Party to
give notice of sale or other disposition of collateral to any Debtor or any
other Person or any defect in any notice that may be given in connection with
any sale or disposition of collateral, (f) any failure of Secured Party to
comply with applicable law in connection with the sale or other disposition of
any collateral or other security for any Secured Obligation, including any
failure of Secured Party to conduct a commercially reasonable sale or other
disposition of any collateral or other security for any Secured Obligation, (g)
any act or omission of Secured Party or others that directly or indirectly
results in or aids the discharge or release of any of any Debtor or the Secured
Obligations or any security or guaranty therefor by operation of law or
otherwise, (h) any law which provides that the obligation of a surety or
guarantor must neither be larger in amount nor in other respects more burdensome
than that of the principal or which reduces a surety's or guarantor's obligation
in proportion to the principal obligation, (i) any failure of Secured Party to
file or enforce a claim in any bankruptcy or other proceeding with respect to
any Person, (j) the election by Secured Party of the application or non-
application of Section 1111(b)(2) of the United States Bankruptcy Code, (k) any
extension of credit or the grant of any lien under Section 364 of the United
States Bankruptcy Code, (l) any use of cash collateral under Section 363 of the
United States Bankruptcy Code, (m) any agreement or stipulation with respect to
the provision of adequate protection in any bankruptcy proceeding of any Person,
(n) the avoidance of any lien in favor of Secured Party for any reason, or (o)
any action taken by Secured Party that is authorized by this section or any
other provision of any Loan Document. Until such time as all of the Secured
Obligations have been fully, finally, and indefeasibly paid in full in cash: (i)
each Debtor hereby waives and postpones any right of subrogation it has or may
have as against any other Debtor with respect to the Secured Obligations; and
(ii) in addition, each Debtor also hereby waives and postpones any right to
proceed or to seek recourse against or with respect to any property or asset of
any other Debtor. Each Debtor expressly waives all setoffs and counterclaims and
all presentments,

                                      -11-
<PAGE>
 
demands for payment or performance, notices of nonpayment or nonperformance,
protests, notices of protest, notices of dishonor and all other notices or
demands of any kind or nature whatsoever with respect to the Secured
Obligations, and all notices of acceptance of this Agreement or of the
existence, creation or incurring of new or additional Secured Obligations.

     In the event that all or any part of the Secured Obligations at any time
are secured by any one or more deeds of trust or mortgages or other instruments
creating or granting liens on any interests in real property, each Debtor
authorizes Secured Party on Secured Party's behalf), upon the occurrence of and
during the continuance of any Event of Default, at its sole option, without
notice or demand and without affecting the obligations of any Debtor, the
enforceability of this Agreement, or the validity or enforceability of any liens
of, or for the benefit of, Secured Party on any collateral, to foreclose any or
all of such deeds of trust or mortgages or other instruments by judicial or
nonjudicial sale.

          To the fullest extent permitted by applicable law, each Debtor
expressly waives any defenses to the enforcement of this Agreement or any rights
of Secured Party created or granted hereby or to the recovery by Secured Party
against any Debtor or any other Person liable therefor of any deficiency after a
judicial or nonjudicial foreclosure or sale, even though such a foreclosure or
sale may impair the subrogation rights of Debtors and may preclude Debtors from
obtaining reimbursement or contribution from other Debtors. Each Debtor
expressly waives any suretyship defenses or benefits that it otherwise might or
would have under applicable law. Each Debtor expressly waives any right to
receive notice of any judicial or nonjudicial foreclosure or sale of any real
property or interest therein of another Debtor that is subject to any such deeds
of trust or mortgages or other instruments and any Debtor's failure to receive
any such notice shall not impair or affect such Debtor's obligations or the
enforceability of this Agreement or any rights of Secured Party created or
granted hereby. WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER
PROVISION SET FORTH IN THIS SECTION, EACH DEBTOR WAIVES ALL RIGHTS AND DEFENSES
ARISING OUT OF AN ELECTION OF REMEDIES BY SECURED PARTY, EVEN THOUGH THAT
ELECTION OF REMEDIES, SUCH AS A NONJUDICIAL FORECLOSURE WITH RESPECT TO SECURITY
FOR THE OBLIGATIONS, HAS DESTROYED SUCH DEBTOR'S RIGHTS OF SUBROGATION AND
REIMBURSEMENT AGAINST THE PRINCIPAL DEBTOR BY THE OPERATION LAW OR OTHERWISE.

          Debtors and each of them warrant and agree that each of the waivers
and consents set forth herein are made after consultation with legal counsel and
with full knowledge of their significance and consequences, with the
understanding that events giving rise to any defense or right waived may
diminish, destroy or otherwise adversely affect rights which Debtors otherwise
may have against other Debtors, Secured Party or others, or against Collateral.
If any of the waivers or consents herein are determined to be contrary to any
applicable law or public policy, such waivers and consents shall be effective to
the maximum extent permitted by law.

          (c)  Interpretation.  In this Agreement, except to the extent the 
               --------------           
context otherwise requires:

               (i)    Any reference to a Section or a Schedule is a reference to
a section hereof, or a schedule hereto, respectively, and to a subsection or a
clause is, unless otherwise stated, a reference to a subsection or a clause of
the Section or subsection in which the reference appears.

               (ii)   The words "hereof," "herein," "hereto," "hereunder" and
the like mean and refer to this Agreement as a whole and not merely to the
specific Section, subsection, paragraph or clause in which the respective word

               (iii)  The meaning of defined terms shall be equally applicable
to both the singular and plural forms of the terms defined.

the respective meanings ascribed to them in the Credit Agreement.

               (ix)   In the event of a direct conflict between the terms and
provisions of this Agreement, on the one hand, and the Credit Agreement or the
applicable Security Agreement, on the other hand, it is the intention of the
parties hereto that both such documents shall be read together and construed, to
the fullest extent possible, to be in concert with each other. In the event of
any actual, irreconcilable conflict that cannot be resolved as aforesaid, the
terms and provisions of the Credit Agreement or the applicable Security
Agreement shall control and govern; provided, however, that the inclusion herein
of additional obligations on the part of the Debtors and supplemental rights and
remedies in favor of Secured Party (whether under California law or applicable
federal law), in each case in respect of the Trademark Collateral, shall not be
deemed a conflict with the Credit Agreement or the applicable Security
Agreement.

business with respect to the Trademark Collateral), and to assign, convey or
otherwise transfer title in or dispose of the Trademark Collateral.  The power
of attorney set forth in this Section 3, being coupled with an interest, is

     4.  Representations and Warranties.  Each Debtor represents and warrants to
         ------------------------------                                         
Secured Party as follows:

          (a)  No Other Trademarks.  Schedule A sets forth a true and correct 
               -------------------   ----------      
list of all of the existing Trademarks that are registered, or for which any
application for registration has been filed with the PTO or any corresponding or
similar trademark office of any other U.S. or foreign jurisdiction, and that are
owned or held (whether pursuant to a license or otherwise) or used by that
Debtor.

          (b)  Trademarks Subsisting.  Each of the Trademarks listed in 
               ---------------------

hereto as owned by it, that Debtor is the sole and exclusive owner
thereof, free and clear of any Liens and rights of others (other than the
security interest created hereunder), including licenses, registered user
agreements and covenants by that Debtor not to sue third persons and (iii) with
respect to any Trademarks for which that Debtor is either a licensor or a
licensee pursuant to a license or licensee agreement regarding such Trademark,
each such license or licensing agreement is in full force and effect, that
Debtor is not in default of any of its obligations thereunder and, other than
the parties to such licenses or licensing agreements, no other Person has any
rights in or to any of the Trademark Collateral. To the best of that Debtor's
knowledge, the past, present and contemplated future use of the Trademark
Collateral by that Debtor has not, does not and will not infringe upon or
violate any right, privilege or license agreement of or with any other Person.

          (d)  No Infringement.  To the best of that Debtor's knowledge, no 
               ---------------                                              
material infringement or unauthorized use presently is being made of any of the
Trademark Collateral by any Person.

          (e)  Powers.  That Debtor has the unqualified right, power and 
               ------                                                    
authority to pledge and to grant to Secured Party a security interest in all of
that Debtor's right, title, and interest in and to the Trademark Collateral
pursuant to this Agreement, and to execute, deliver and perform its obligations
in accordance with the terms of this Agreement, without the consent or approval
of any other Person except as already obtained.

     5.   Covenants.  So long as any of the Secured Obligations remain
          ---------                                                   
unsatisfied, each Debtor agrees that it will comply with all of the covenants,
terms and provisions of this Agreement, the Credit Agreement and the other Loan
Documents, and each Debtor will promptly give Secured Party written notice of
the occurrence of any event that could have a material adverse effect on any of
the Trademarks or the Trademark Collateral, including any petition under the
Bankruptcy Code filed by or against any licensor of any of the Trademarks for
which Debtor is a licensee.

     6.   Future Rights.  Except as otherwise expressly agreed to in writing by
          -------------                                                        
Secured Party, for so long as any of the Secured Obligations shall remain
outstanding, or, if earlier, until Secured Party shall have released or
terminated, in whole but not in part, its interest in the Trademark Collateral,
if and when any Debtor shall obtain rights to any new Trademarks, or any
reissue, renewal or extension of any Trademarks, the provisions of Section 2
shall automatically apply thereto and that Debtor shall give to Secured Party
prompt notice thereof.  Each Debtor shall do all things deemed necessary or
advisable by Secured Party to ensure the validity, perfection, priority and
enforceability of the security interests of Secured Party in such future
acquired Trademark Collateral.  Each Debtor hereby authorizes Secured Party to
modify, amend or supplement the Schedules hereto and to re-execute this
Agreement from time to time on that Debtor's behalf and as its attorney-in-fact
to include any future 

                                      -6-

Trademarks which are or become Trademark Collateral and to cause such re-

filed with the PTO.

     7.   Secured Party's Duties.  Notwithstanding any provision contained in 
          ----------------------                                           
this Agreement, Secured Party shall have no duty to exercise any of the rights,
privileges or powers afforded to it and shall not be responsible to any Debtor
or any other Person for any failure to do so or delay in doing so.  Except for
the accounting for moneys actually received by Secured Party hereunder or in
connection herewith, Secured Party shall have no duty or liability to exercise
or preserve any rights, privileges or powers pertaining to the Trademark
Collateral.

     8.   Remedies.  Secured Party shall have all rights and remedies 
          --------                                                    
available to it under the Credit Agreement, the Security Agreements, and
applicable law (which rights and remedies are cumulative) with respect to the
security interests in any of the Trademark Collateral or any other Collateral.
Each Debtor agrees that such rights and remedies include the right of Secured
Party as a secured party to sell or otherwise dispose of its Collateral after
default, pursuant to UCC Section 9504. Each Debtor agrees that Secured Party
shall at all times have such royalty free licenses, to the extent permitted by
law, for any Trademark Collateral that is reasonably necessary to permit the
exercise of any of Secured Party's rights or remedies upon or after the
occurrence of (and during the continuance of) an Event of Default with respect
to (among other things) any tangible asset of the Debtors in which Secured Party
has a security interest, including Secured Party's rights to sell inventory,
tooling or packaging which is acquired by the Debtors (or their respective
successors, permitted assignees or trustees in bankruptcy). In addition to and
without limiting any of the foregoing, upon the occurrence and during the
continuance of an Event of Default, Secured Party shall have the right but shall
in no way be obligated to bring suit, or to take such other action as Secured
Party deems necessary or advisable, in the name of any Debtor or Secured Party,
to enforce or protect any of the Trademark Collateral, in which event each
Debtor shall, at the request of Secured Party, do any and all lawful acts and
execute any and all documents required by Secured Party in aid of such
enforcement. To the extent that Secured Party shall elect not to bring suit to
enforce such Trademark Collateral, each Debtor agrees to use all reasonable
measures and its diligent efforts, whether by action, suit, proceeding or
otherwise, to prevent the infringement, misappropriation or violation thereof by
others and for that purpose agrees diligently to maintain any action, suit or
proceeding against any Person necessary to prevent such infringement,
misappropriation or violation.

     9.   Binding Effect.  This Agreement shall be binding upon, inure to the
          --------------                                                     
benefit of and be enforceable by each Debtor and Secured Party and their
respective successors and permitted assigns.

     10.  Notices.  All notices and other communications hereunder to or from
          -------                                                            
Secured Party or any Debtor shall be in writing and shall be mailed, sent or
delivered in accordance with the Credit Agreement.

     15.  Credit Agreement and Security Agreements.  Each Debtor acknowledges 
          ----------------------------------------

interest in the Trademark Collateral granted hereby are more fully set forth in
the Credit Agreement, the Security Agreements, and the other Loan Documents and
all such rights and remedies are cumulative.

     16.  No Inconsistent Requirements.  Each Debtor acknowledges that this
          ----------------------------                                     
Agreement and the other Loan Documents may contain covenants and other terms and
provisions variously stated regarding the same or similar matters, and each

all shall be performed and satisfied in accordance with their respective terms.

     17.  Termination.  Upon the indefeasible payment in full of the Secured
          -----------                                                       
Obligations, including the cash collateralization, expiration, or cancellation
of all Secured Obligations, if any, consisting of letters of credit, and the
full and final termination of any commitment to extend any financial

expense as shall be necessary to evidence termination of the security interest
granted by that Debtor to Secured Party hereunder.

     18.  Suretyship Waivers and Consents.  Each Debtor acknowledges that the
          -------------------------------                                    
obligations of such Debtor undertaken herein might be construed to consist, at
least in part, of the guaranty of obligations of Persons or entities other than
such Debtor (including the other Debtors party hereto) and, in full recognition
of that fact, each Debtor consents and agrees that Secured Party may, at any
time and from time to time, without notice or demand, whether before or after
any actual or purported termination, repudiation or revocation of this Agreement
by any one or more Debtors, and without affecting the enforceability or
continuing effectiveness hereof as to each Debtor: (a) if it has so agreed with
the applicable other Debtors, supplement,

otherwise change the time for payment or the terms of the Secured Obligations or
any part thereof, including any increase or decrease of the rate(s) of interest
thereon; (b) supplement, restate, modify, amend, (if it has so agreed with the
applicable other Debtors) increase, decrease or waive, or enter into or give any
agreement, approval or consent with respect to, the Secured Obligations or any
part thereof, or any of the Loan Documents or any additional security or
guarantees, or any condition, covenant, default, remedy, right, representation
or term thereof or thereunder; (c) accept new or additional instruments,
documents or agreements in exchange for or relative to any of the Loan Documents
or the Secured Obligations or any part thereof; (d) accept partial payments on
the Secured Obligations; (e) receive and hold additional security or guarantees
for the Secured Obligations or any part thereof; (f) release, reconvey,
terminate, waive, abandon, fail to perfect, subordinate, exchange, substitute,

absolute discretion may determine; (g) release any Person from any personal
liability with respect to the Secured Obligations or any part thereof; (h)
settle, release on terms satisfactory to Secured Party or by operation of
applicable laws or otherwise liquidate or enforce any Secured Obligations and
any security therefor or guaranty thereof in any manner, consent to the transfer
of any security and bid and purchase at any sale; or (i) consent to the merger,
change or any other restructuring or termination of the corporate or partnership
existence of any Debtor or any other Person, and correspondingly restructure the
Secured Obligations, and any such merger, change, restructuring or termination

hereof, or the enforceability hereof with respect to all or any part of the
Secured Obligations.

          Upon the occurrence and during the continuance of any Event of
Default, Secured Party may enforce this Agreement independently as to each
Debtor and independently of any other remedy or security Secured Party at any
time may have or hold in connection with the Secured Obligations, and it shall
not be necessary for Secured Party to marshal assets in favor of any Debtor or
any other Person or to proceed upon or against or exhaust any security or remedy
before proceeding to enforce this Agreement. Each Debtor expressly waives any
right to require Secured Party to marshal assets in favor of any Debtor or any
other Person or to proceed against any other Debtor or any collateral provided
by any Person, and agrees that Secured Party may proceed against Debtors or any
collateral in such order as it shall determine in its sole and absolute
discretion .

          Secured Party may file a separate action or actions against any
Debtor, whether action is brought or prosecuted with respect to any security or
against any other Person, or whether any other Person is joined in any such
action or actions. Each Debtor agrees that Secured Party and any Debtor and any
Affiliate of any Debtor may deal with each other in connection with the Secured
Obligations or otherwise, or alter any contracts or agreements now or hereafter
existing between any of them, in any manner whatsoever, all without in any way
altering or affecting the continuing efficacy of this Agreement.

<PAGE>
 
          Secured Party's rights hereunder shall be reinstated and revived, and
the enforceability of this Agreement shall continue, with respect to any amount
at any time paid on account of the Secured Obligations which thereafter shall be
required to be restored or returned by Secured Party, all as though such amount
had not been paid. The rights of Secured Party created or granted herein and the
enforceability of this Agreement at all times shall remain effective to cover
the full amount of all the Secured Obligations even though the Secured
Obligations, including any part thereof or any other security or guaranty
therefor, may be or hereafter may become invalid or otherwise unenforceable as
against any Debtor and whether or not any other Debtor shall have any personal
liability with respect thereto.

          To the maximum extent permitted by applicable law, each Debtor
expressly waives any and all defenses now or hereafter arising or asserted by
reason of (a) any disability or other defense of any other Debtor with respect
to the Secured Obligations, (b) the unenforceability or invalidity of any
security or guaranty for the Secured Obligations or the lack of perfection or
continuing perfection or failure of priority of any security for the Secured
Obligations, (c) the cessation for any cause whatsoever of the liability of any
other Debtor (other than by reason of the full payment and performance of all
Secured Obligations), (d) any failure of Secured Party to marshal assets in
favor of any Debtor or any other Person, (e) any failure of Secured Party to
give notice of sale or other disposition of collateral to any Debtor or any
other Person or any defect in any notice that may be given in connection with
any sale or disposition of collateral, (f) any failure of Secured Party to
comply with applicable law in connection with the sale or other disposition of
any collateral or other security for any Secured Obligation, including any
failure of Secured Party to conduct a commercially reasonable sale or other
disposition of any collateral or other security for any Secured Obligation, (g)
any act or omission of Secured Party or others that directly or indirectly
results in or aids the discharge or release of any of any Debtor or the Secured
Obligations or any security or guaranty therefor by operation of law or
otherwise, (h) any law which provides that the obligation of a surety or
guarantor must neither be larger in amount nor in other respects more burdensome
than that of the principal or which reduces a surety's or guarantor's obligation
in proportion to the principal obligation, (i) any failure of Secured Party to
file or enforce a claim in any bankruptcy or other proceeding with respect to
any Person, (j) the election by Secured Party of the application or non-
application of Section 1111(b)(2) of the United States Bankruptcy Code, (k) any
extension of credit or the grant of any lien under Section 364 of the United
States Bankruptcy Code, (l) any use of cash collateral under Section 363 of the
United States Bankruptcy Code, (m) any agreement or stipulation with respect to
the provision of adequate protection in any bankruptcy proceeding of any Person,
(n) the avoidance of any lien in favor of Secured Party for any reason, or (o)
any action taken by Secured Party that is authorized by this section or any
other provision of any Loan Document. Until such time as all of the Secured
Obligations have been fully, finally, and indefeasibly paid in full in cash: (i)
each Debtor hereby waives and postpones any right of subrogation it has or may
have as against any other Debtor with respect to the Secured Obligations; and
(ii) in addition, each Debtor also hereby waives and postpones any right to
proceed or to seek recourse against or with respect to any property or asset of
any other Debtor. Each Debtor expressly waives all setoffs and counterclaims and
all presentments,

                                      -11-
<PAGE>
 
demands for payment or performance, notices of nonpayment or nonperformance,
protests, notices of protest, notices of dishonor and all other notices or
demands of any kind or nature whatsoever with respect to the Secured
Obligations, and all notices of acceptance of this Agreement or of the
existence, creation or incurring of new or additional Secured Obligations.

     In the event that all or any part of the Secured Obligations at any time
are secured by any one or more deeds of trust or mortgages or other instruments
creating or granting liens on any interests in real property, each Debtor
authorizes Secured Party on Secured Party's behalf), upon the occurrence of and
during the continuance of any Event of Default, at its sole option, without
notice or demand and without affecting the obligations of any Debtor, the
enforceability of this Agreement, or the validity or enforceability of any liens
of, or for the benefit of, Secured Party on any collateral, to foreclose any or
all of such deeds of trust or mortgages or other instruments by judicial or
nonjudicial sale.

     To the fullest extent permitted by applicable law, each Debtor expressly
waives any defenses to the enforcement of this Agreement or any rights of
Secured Party created or granted hereby or to the recovery by Secured Party
against any Debtor or any other Person liable therefor of any deficiency after a
judicial or nonjudicial foreclosure or sale, even though such a foreclosure or
sale may impair the subrogation rights of Debtors and may preclude Debtors from
obtaining reimbursement or contribution from other Debtors.  Each Debtor
expressly waives any suretyship defenses or benefits that it otherwise might or
would have under applicable law.  Each Debtor expressly waives any right to
receive notice of any judicial or nonjudicial foreclosure or sale of any real
property or interest therein of another Debtor that is subject to any such deeds
of trust or mortgages or other instruments and any Debtor's failure to receive
any such notice shall not impair or affect such Debtor's obligations or the
enforceability of this Agreement or any rights of Secured Party created or
granted hereby.  WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER
PROVISION SET FORTH IN THIS SECTION, EACH DEBTOR WAIVES ALL RIGHTS AND DEFENSES
ARISING OUT OF AN ELECTION OF REMEDIES BY SECURED PARTY, EVEN THOUGH THAT
ELECTION OF REMEDIES, SUCH AS A NONJUDICIAL FORECLOSURE WITH RESPECT TO SECURITY
FOR THE OBLIGATIONS, HAS DESTROYED SUCH DEBTOR'S RIGHTS OF SUBROGATION AND
REIMBURSEMENT AGAINST THE PRINCIPAL DEBTOR BY THE OPERATION LAW OR OTHERWISE.

     Debtors and each of them warrant and agree that each of the waivers and
consents set forth herein are made after consultation with legal counsel and
with full knowledge of their significance and consequences, with the
understanding that events giving rise to any defense or right waived may
diminish, destroy or otherwise adversely affect rights which Debtors otherwise
may have against other Debtors, Secured Party or others, or against Collateral.
If any of the waivers or consents herein are determined to be contrary to any
applicable law or public policy, such waivers and consents shall be effective to
the maximum extent permitted by law.

The Board of Directors
MDT Corporation:


We consent to incorporation by reference in the registration statements, No. 33-
30613 on Form S-8; No. 33-18062 on Form S-8; No. 33-20326 on Form S-8; and No.
33-23906 on Form S-8, of MDT Corporation of our report dated May 17, 1996,
except as to the third paragraph of note 9 and the second paragraph of note 17,
which are as of July 12, 1996, relating to the consolidated balance sheets of
MDT Corporation and subsidiaries as of March 31, 1996 and 1995, and the related
consolidated statements of income (loss), stockholders' equity and cash flows
for each of the years in the three-year period ended March 31, 1996, and the
related schedule, which report appears in the March 31, 1996 Annual Report on
Form 10-K of MDT Corporation.

Our report contains an explanatory paragraph that states that the status of the
Company's existing credit facilities and the need for borrowing capacity during
fiscal 1997 raise substantial doubt about the Company's ability to continue as a
going concern. The consolidated financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

                          Independent Auditors' Report
                          ----------------------------


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, 1995 and 1994, 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 as of December 31, 1995
and 1994, and the changes in 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, 1995 and 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.

                         Notes to Financial Statements



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

     Use of Estimates
     ----------------

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires the plan administrator to make
     estimates and assumptions that affect the reported amounts of net assets
     available for plan benefits as of the date of the financial statements and
     the reported amounts of income during the reporting period. Actual results
     could differ from those estimates.

     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.

     Reclassification
     ----------------

     Certain 1994 financial statement amounts have been reclassified to conform
     to the current year presentation.

                         Notes to Financial Statements



(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, 1995 and 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 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 Other fund is a short-term investment fund utilized by the Plan and is
     not an investment option available to the participants. The purpose of this
     fund is to hold unallocated funds relating to forfeitures,
     contribution/loan repayment funding differences, and contribution/loan
     repayment funding prior to being allocated to the appropriate investment
     funds. Based on participant direction, the investment earnings are
     allocated to the appropriate investment funds. Based on participant
     direction, the investment earnings are allocated to the appropriate
     investment options coincident with the record keeping update.

     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, 1995 and 1994 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 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.


(7)  Subsequent Events
     -----------------

     Tender Offer of Sponsor Shares
     ------------------------------

     MDT Corporation, the Plan sponsor, is the subject of a pending public 
     tender offer for its outstanding shares.
     
     Effective May 17, 1996, the Plan was amended to require the trustee to
     notify participants and inquire as to whether the Company stock allocated
     to participants' accounts for purposes of a public offering should be
     tendered. Each participant may elect that all, but not less than all, of
     the Company stock allocated to his account be tendered by the trustee on
     his behalf.

     Any securities or other property received by the trustee as a result of
     having tendered Company stock shall be held, and any cash received be
     invested in short-term investments, pending further action the trustee may
     be required or directed to take, including elections by participants to
     transfer such amounts to another fund. Effective September 30, 1996, any
     such funds remaining tin the MDT Stock Fund shall be transferred to the
     Asset Management Fund II, andy any election by a participant that
     contributions be invested in the MDT Stock Fund shall be deemed an election
     to invest in the Asset Management Fund II.


     Effective July 1, 1996, the Plan was rewritten to provide that MDT
     Corporation Retirement Plan accounts be transferred to the Plan.
     Additionally, the Plan was renamed the MDT Corporation Retirement Savings
     Plan for Hourly Employees. Moreover, the Plan rewrite provided a health
     plan component such that amounts distributed on account of total and
     permanent disability, as defined, are excluded from income under the
     Internal Revenue Code.

                          ----------------------------
                                        
 
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, 1995 and 1994, 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 as of December 31,
1995 and 1994, and the changes in 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, 1995 and 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.

                         Notes to Financial Statements



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

     Use of Estimates
     ----------------

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires the plan administrator to make
     estimates and assumptions that affect the reported amounts of net assets
     available for plan benefits as of the date of the financial statements and
     the reported amounts of income during the reporting period. Actual results
     could differ from those estimates.

     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.

     Reclassification
     ----------------

     Certain 1994 financial statement amounts have been reclassified to conform
     to the current year presentation.

                         Notes to Financial Statements



(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, 1995 and 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 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 Other fund is a short-term investment fund utilized by the Plan and is
     not an investment option available to the participants. The purpose of this
     fund is to hold unallocated funds relating to forfeitures,
     contribution/loan repayment funding differences, and contribution/loan
     repayment funding prior to being allocated to the appropriate investment
     funds. Based on participant direction, the investment earnings are
     allocated to the appropriate investment options coincident with the record
     keeping update.

     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, 1995 and 1994 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 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.


(7)  Subsequent Events
     -----------------

     Tender Offer of Sponsor Shares
     ------------------------------

     MDT Corporation, the Plan sponsor, is the subject of a pending public 
     tender offer for its outstanding shares.

     Effective May 17, 1996, the Plan was amended to require the trustee to
     notify participants and inquire as to whether the Company stock allocated
     to participants' accounts for purposes of a public offering should be
     tendered. Each participant may elect that all, but not less than all, of
     the Company stock allocated to his account be tendered by the trustee on
     his behalf.

     Any securities or other property received by the trustee as a result of
     having tendered Company stock shall be held, and any cash received be
     invested in short-term investments, pending further action the trustee may
     be required or directed to take, including elections by participants to
     transfer such amounts to another fund. Effective September 30, 1996, any
     such funds remaining in the MDT Stock Fund shall be transferred to the
     Asset Management Fund II, and any election by a participant that
     contributions be invested in the MDT Stock Fund shall be deemed an election
     to invest in the Asset Management Fund II.

     Effective July 1, 1996, the Plan was rewritten to provide that MDT
     Corporation Retirement Plan accounts be transferred to the Plan.
     Additionally, the Plan was renamed the MDT Corporation Retirement Savings
     Plan for Salaried Employees. Moreover, the Plan rewrite provided a health
     plan component such that amounts distributed on account of total and
     permanent disability, as defined, are excluded from income under the
     Internal Revenue Code.

                          Independent Auditors' Report
                          ----------------------------


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, 1995 and 1994, 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 as of December 31, 1995
and 1994, and the changes in 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, 1995 and 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.

     Use of Estimates
     ----------------

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires the plan administrator to make
     estimates and assumptions that affect the

                              FOR UNION EMPLOYEES

                         Notes to Financial Statements



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

     reported amounts of net assets available for plan benefits as of the date
     of the financial statements and the reported amounts of income during the
     reporting period. Actual results could differ from those estimates.

     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.

     Reclassification
     ----------------

     Certain 1994 financial statement amounts have been reclassified to conform
     to the current year presentation.


(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, 1995 and 1994, market
     value of loans approximates fair value.

                         Notes to Financial Statements



(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 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, 1995 and 1994 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 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.
